Small Cap Growth Fund

GOAL AND STRATEGY

[Clip art] The fund seeks long-term capital appreciation. To pursue this goal,
the fund normally invests at least 80% of assets in stocks of U.S. emerging
growth companies with market capitalizations of no more than $1 billion. The
managers look for companies that show rapid growth but are not yet widely
recognized. The fund also may invest in established companies that, because of
new management, products or opportunities, offer the possibility of accelerating
earnings.

In managing the portfolio, the managers emphasize diversification by sector and
company. The fund's investments by sector, or sector weightings, generally
reflect those of the Russell 2000 Growth Index. The fund normally invests in 150
to 220 companies.

In choosing individual securities, the managers use fundamental financial
analysis to identify rapidly growing companies. The managers favor companies
that dominate their market niches or are poised to become market leaders. They
look for strong senior management teams and coherent business strategies. They
generally maintain personal contact with the senior management of the companies
the fund invests in.

The fund may invest up to 20% of assets in other types of companies and certain
other types of equity and debt securities. The fund may make limited use of
certain derivatives (investments whose value is based on indices, securities or
currencies).

In abnormal market conditions, the fund may temporarily invest more than 20% 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] The graph shows how the fund's total return has varied from year to
year, while the table shows performance over time (along with broad-based market
indices for reference). This information may help provide an indication of the
fund's risks. Since the Class I shares have no operational history, the
year-by-year and average annual figures are for Class B shares which are offered
in a separate prospectus. The average annual figures reflect sales charges; the
year-by-year and index figures do not, and would be lower if they did. Class I
shares have no sales charges and lower expenses than the Class B shares. All
figures assume dividend reinvestment. Past performance does not indicate future
results.

MAIN RISKS

[Clip art] As with most growth funds, the value of your investment will go up
and down in response to stock market movements. Because the fund concentrates on
emerging growth companies, its performance may be more volatile than that of a
fund that invests primarily in larger companies.

Stocks of smaller emerging growth companies are more risky than stocks of larger
companies. Many of these companies are young and have a limited track record.
Because their businesses frequently rely on narrow product lines and niche
markets, they can suffer severely from isolated business setbacks.

The fund's management strategy will influence performance significantly.
Emerging growth stocks as a group could fall out of favor with the market,
causing the fund to underperform funds that focus on other types of stocks.
Similarly, if the managers' stock selection strategy does not perform as
expected, the fund could underperform its peers or lose money.

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

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

o Certain derivatives could produce disproportionate gains or losses.

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

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

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

YOUR EXPENSES

[Clip art] Operating expenses are paid from the fund's assets, and therefore are
paid by shareholders indirectly. Because Class I is new, its expenses are based
on Class B expenses, adjusted to reflect any changes.

- --------------------------------------------------------------------------------
Annual operating expenses
- --------------------------------------------------------------------------------
Management fee 0.75%
Other expenses 0.22%
Total fund operating expenses 0.97%

The hypothetical example below shows what your expenses would be if you invested
$10,000 over the time frames indicated, assuming you reinvested all
distributions and that the average 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.

TRANSACTION POLICIES
- --------------------------------------------------------------------------------

Valuation of shares The net asset value per share (NAV) for the fund 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 also value securities at fair value
if the value of these securities has been materially affected by events occuring
after the close of a foreign market. 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. When you sell shares,
you receive the NAV.

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

Telephone transactions For your protection, telephone requests may be recorded
in order to verify their accuracy. Also for your protection, telephone
transactions are not permitted on accounts whose names or addresses have changed
within the past 30 days. Proceeds from telephone transactions can only be mailed
to the address of record.

Exchanges You may exchange shares of one institutional fund for shares of any
other institutional fund or other Class I shares. The registration for both
accounts involved must be identical.

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

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

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

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

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

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

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

o in all other circumstances, every month

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

Dividends The funds declare and pay any income dividends annually. Capital
gains, if any, are distributed annually.

Dividend reinvestments Dividends will be reinvested automatically in additional
shares of the same fund 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.

10 YOUR ACCOUNT
<PAGE>

Taxability of dividends For investors who are not exempt from federal income
taxes, dividends you receive from a fund, whether reinvested or taken as cash,
are generally considered taxable. Dividends from a fund's short-term capital
gains are taxable as ordinary income. Dividends from a fund's long-term capital
gains are taxable at a lower rate. 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 if you are not exempt from federal income
taxes. 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.

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.

Special investment privilege If you sell your shares as a result of withdrawing
from your retirement plan, you will not be able to withdraw the proceeds and
reinvest them in fund shares. However, you can reinvest in Class A shares of any
John Hancock fund without paying a front-end sales charge. This privilege is
available whether you reinvest into a taxable account or roll the proceeds into
an IRA. If you reinvest in a taxable account, you may be subject to 20% tax
withholding on the amount of your distribution.

ORGANIZATION OF THE FUND

The Fund is a series of the Trust, an open-end investment management company
organized as a Massachusetts business trust under a Declaration of Trust dated
December 2, 1996. Prior to December 2, 1996, the Fund was a series of John
Hancock Technology Series, Inc., a Maryland corporation. On December 2, 1996,
the Trust assumed the Registration Statement of John Hancock Technology Series,
Inc. Prior to April 1, 1999, the Fund was called John Hancock Emerging Growth
Fund.

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

INVESTMENT OBJECTIVE AND POLICIES

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

The Fund seeks long-term capital appreciation. The Fund invests primarily in
emerging companies (market capitalization of less than $1 billion). In normal
circumstances, the Fund will invest at least 80% of its assets in these
companies. Current income is not a factor of consequence in the selection of
stocks for the Fund.

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

The Fund currently favors companies that have demonstrated 20% annual growth
over three years and are projected to continue growing at a similar pace. This
strategy can be changed at any time.

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

2
<PAGE>

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

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

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

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

Investment In Foreign Securities. The Fund may invest in securities of foreign
issuers including securities in the form of sponsored and unsponsored American
Depository Receipts ("ADRs") European Depository Receipts (EDRs) or other
securities convertible into securities of foreign issuers. These securities may
not necessarily be denominated in the same currency as the securities into which
they may be converted but rather in the currency of the market in which they are
traded. ADRs are receipts typically issued by an American bank or trust company
which evidence ownership of underlying securities issued by a foreign
corporation. Generally, ADRs, in registered form, are designed for use in United
States securities markets and EDRs are designed for use in foreign securities
markets. Issuers of unsponsored ADRs are not contractually obligated to disclose
material information including financial information, in the United States.

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

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

3
<PAGE>

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

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

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

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

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

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

These risks may be intensified in the case of investments in emerging markets or
countries with limited or developing capital markets. These countries are
located in the Asia-Pacific region, Eastern Europe, Latin and South America and
Africa. Security prices in these markets can be significantly more volatile than
in more developed countries, reflecting the greater uncertainties of investing
in less established markets and economies. Political, legal and economic
structures in many of these emerging market countries may be undergoing
significant evolution and rapid development, and they may lack the social,
political, legal and economic stability characteristic of more developed
countries. Emerging market countries may have failed in the past to recognize
private property rights. They may have relatively unstable governments, present
the risk of nationalization of businesses, restrictions on foreign ownership, or
prohibitions

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

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

If the Fund enters into a forward contract to purchase foreign currency, the
fund will segregate cash or liquid securities, of any type or maturity, in a
separate account in an amount necessary to complete forward contract. These
assets will be marked to market daily and if the value of the assets in the
separate account declines, additional cash or liquid assets will be added so
that the value of the account will equal the amount of the Fund's commitments in
purchased forward contracts.

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

5
<PAGE>

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

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

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

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

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

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

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

6
<PAGE>

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

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

The Fund has established a procedure providing that the securities serving as
collateral for each repurchase agreement must be delivered to the Fund's
custodian either physically or in book-entry form and that the collateral must
be marked to market daily to ensure that each repurchase agreement is fully
collateralized at all times. In the event of bankruptcy or other default by a
seller of a repurchase agreement, the Fund could experience delays in
liquidating the underlying securities and could experience losses, including the
possible decline in the value of the underlying securities during the period in
which the Fund seeks to enforce its rights thereto, possible subnormal levels of
income, a decline in value of the underlying securities or lack of access to
income during this period, as well as the expense of enforcing its rights. The
Fund will not invest in a repurchase agreement maturing in more than seven days,
if such investment, together with other illiquid securities held by the Fund
(including restricted securities) would exceed 10% of the Fund's net assets.

Reverse Repurchase Agreements. The Fund may also enter into reverse repurchase
agreements which involve the sale of 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. To minimize various risks
associated with reverse repurchase agreements, the Fund will establish and
maintain a separate account consisting of liquid securities, of any type or
maturity, in an amount at least equal to the repurchase prices of the securities
(plus any accrued interest thereon) under such agreements. The Fund will also
continue to be subject to the risk of a decline in the market value of the
securities sold under the agreements because it will reacquire those securities
upon effecting their repurchase. The Fund will not enter into reverse repurchase
agreements exceeding in the aggregate 33 1/3% of the market value of its total
assets. The Fund will enter into reverse repurchase agreements only with
federally insured banks or savings and loan associations which are approved in
advance as being creditworthy by the Trustees. Under procedures established by
the Trustees, the Adviser will monitor the creditworthiness of the banks
involved.

7
<PAGE>

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

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

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

All call and put options written by the Fund are covered. A written call option
or put option may be covered by (i) maintaining cash or liquid securities,
either of which may be quoted or denominated in any currency, in a segregated
account 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.

8
<PAGE>

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

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

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

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

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

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

9
<PAGE>

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

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

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

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

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

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

Hedging and Other Strategies. Hedging is an attempt to establish with more
certainty than would otherwise be possible the effective price or rate of return
on portfolio securities or securities that the Fund proposes to acquire or the
exchange rate of currencies in which portfolio securities are quoted or
denominated. 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 seek to offset anticipated changes in the value of a currency in
which its portfolio securities, or securities that it intends to purchase, are
quoted or denominated by purchasing and selling futures contracts on such
currencies.

10
<PAGE>

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

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

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

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

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

11
<PAGE>

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

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

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

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

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

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

12
<PAGE>

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

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

Lending of Securities. The Fund may lend portfolio securities to brokers,
dealers, and financial institutions if the loan is collateralized by cash or
U.S. government securities according to applicable regulatory requirements. The
Fund may reinvest any cash collateral in short-term securities and money market
funds. When the Fund lends portfolio securities, there is a risk that the
borrower may fail to return the securities involved in the transaction. As a
result, the Fund may incur a loss or, in the event of the borrower's bankruptcy,
the Fund may be delayed in or prevented from liquidating the collateral. The
Fund may not lend portfolio securities having a total value exceeding 30% of its
total assets.

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

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

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

<PAGE>

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

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

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

INVESTMENT RESTRICTIONS

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

The Fund may not:

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

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

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

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

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

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

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

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

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

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

<PAGE>

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

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

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

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

Other Operating Policies

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

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