                               OVERVIEW OF FUNDS


MONEY MARKET FUND

INVESTMENT OBJECTIVE AND PRINCIPAL STRATEGY
The investment objective of the Money Market Fund is to maximize current income
to the extent consistent with the preservation of capital and maintenance of
liquidity. The Fund seeks to achieve its objective by investing in a portfolio
of high-quality, short-term money market instruments which include:
- -  U.S Government securities
- -  Certificates of deposit and time deposits issued by U.S. banks
- -  Repurchase agreements with banks or government securities dealers
- -  Commercial paper (unsecured promissory notes issued by corporations to
   finance short-term credit needs)

The Fund will invest only in U.S. dollar-denominated instruments maturing in 13
months or less. The average maturity of the Fund's portfolio securities based on
their dollar value will not exceed 90 days at the time of each investment. By
restricting the maturity of its investments, the Fund seeks to limit changes in
the value of its assets resulting from market factors in order to maintain a
constant net asset value of $1.00 per share. See "Net Asset Value."

PRINCIPAL RISKS
The Fund invests in securities that may not earn as high a level of current
income as long-term or lower quality securities. The rate of return to
shareholders will vary with the general levels of interest rates that apply to
short-term, high quality debt instruments. Changes in the Fund's operating
expenses will also affect the rate of return.

An investment in the Fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although the Fund seeks
to preserve the value of your investment at $1.00 per share, it is possible to
lose money by investing in the Fund.

THIS FUND MAY BE APPROPRIATE FOR:
- -  Conservative investors primarily concerned with stability of principal
- -  Investors needing liquidity to match shorter-term investment goals


7 DAY YIELD
- -----------

As of December 31, 1998, the 7 day effective yield was 5.15%.

perform in the future.

GOVERNMENT SECURITIES FUND

INVESTMENT OBJECTIVE AND PRINCIPAL STRATEGY
The investment objective of the Government Securities Fund is to seek high
current income with limited credit risk through investing in intermediate and
long-term debt instruments issued or guaranteed by the U.S. Government, its
agencies or instrumentalities. The Government Securities Fund will invest at
least 80% of its total assets in U.S. Government securities of various
maturities. The U.S. Government securities in which the Fund may invest include:
- -  U.S. Treasury bills, notes, and bonds

And obligations issued or guaranteed by U.S. Government agencies and
instrumentalities, including those of:

- -  Government National Mortgage Association ("GNMA")
- -  Federal Home Loan Banks
- -  Federal National Mortgage Association ("FNMA")
- -  Federal Land Banks
- -  Farmer's Home Administration
- -  Student Loan Marketing Association

The Fund seeks to enhance returns by varying the average maturity of the
portfolio. Generally, the average maturity is between three to twelve years. The
Fund has in the past invested pricipally in non-callable, non-prepayable
securities with an emphasis on obligations issued or guaranteed by U.S.
Government agencies. However, the fund has the flexibility to invest up to 50%
of its net assets in securities of the GNMA and FNMA and may invest in certain
other securities which may involve a risk of early repayment of principal.
Prevailing interest rates at the time of such prepayments may be lower than the
current yield of the Fund; therefore, such prepayment could adversely affect the
yield of the fund. If the Fund is attempting to adjust the average maturity or
take advantage of relatively attractive prices, it may sell securities within
the portfolio.

PRINCIPAL RISKS
The Government Securities Fund is subject to the risks associated with investing
in longer-term fixed income securities such as bonds. Bonds are issued to
evidence loans that investors make to corporations and governments. They are
vulnerable principally to interest rate risk, but are also exposed to market
risk. See "Types of Investment Risk."

The value of U.S. Government securities owned by the Government Securities Fund
will fluctuate in response to various market forces and will generally vary
inversely with prevailing interest rate levels. Therefore, the value of an
investment in the Fund also will fluctuate and you may lose money investing in
this Fund. In this regard, any U.S. Government or agency guarantee of securities
held in the Government Securities Fund does not guarantee the value of an
investment in

                                       2
<PAGE>

the Fund.

THIS FUND MAY BE APPROPRIATE FOR:
- -  Investors seeking an opportunity for higher income and capital appreciation
   unavailable with shorter-term debt investments
- -  Investors who desire the relative credit safety that U.S. Government
   securities offer

The bar chart and table below illustrate how performance can vary and give you
an indication of the risks of investing in the Fund. The bar chart shows the
Fund's performance for each full calendar year since inception. The table shows
how the Fund's average annual returns for one year and inception to date compare
with those of the Lehman Brothers U.S. Government Bond Index. The information
assumes the reinvestment of all dividends and distributions. Keep in mind that
the Fund's past performance does not indicate how it will perform in the future.

ASSET ALLOCATION FUND

INVESTMENT OBJECTIVE AND PRINCIPAL STRATEGY
The investment objective of the Asset Allocation Fund is to maximize total
return on invested capital, to be derived from capital appreciation, dividends
and interest. This Fund follows a flexible asset allocation strategy that shifts
among a wide range of investments and markets. Assets are invested in equity
securities, debt securities and money market instruments, the proportion of each
being continuously determined by the Adviser. The Fund generally seeks to
acquire equity securities of businesses that generate significant operating
margins, strong cash flow, or high returns on capital. The Adviser evaluates the
purchase price of the stock in relation to historical and projected earnings and
cash flow. The Fund seeks to buy those equities where the price is reasonable
relative to the projected growth in the earnings and cash flow of the business.
The Fund may invest in small, mid-capitalization and large companies. The Fund
buys primarily U.S. Treasury securities and investment grade bonds for the fixed
income portion of the portfolio. The Fund may sell

                                       3
<PAGE>

equity securities when, based on earnings, or valuation, they no longer are
attractive. The Fund may sell debt securities if their fundamental qualities
deteriorate or to take advantage of more attractive yield opportunities.

PRINCIPAL RISKS
The Asset Allocation Fund is subject to the risks associated with investing in
both equity securities and bonds. These risks include market risk, event risk,
interest rate risk, credit risk, and political/legal risk. The Asset Allocation
Fund is also vulnerable to small/mid-capitalization company risk. "See Types of
Investment Risk." The value of an investment in the Fund will fluctuate, and you
may lose money investing in the Fund.

THIS FUND MAY BE APPROPRIATE FOR:
- -  Investors wishing to invest in a mix of stocks, bonds and money market
   instruments within the same mutual fund
- -  Investors who want a professional investment advisor to make their
   investment allocation decisions

The bar chart and table below illustrate how performance can vary and give you
an indication of the risks of investing in the Fund. The bar chart shows the
Fund's performance for each full calendar year since inception. The table shows
how the Fund's average annual returns for one year and inception to date compare

S&P 500 INDEX FUND

INVESTMENT OBJECTIVE AND PRINCIPAL STRATEGY
The investment objective of the S&P 500 Index Fund is to provide capital
appreciation and accumulation of income that corresponds to the investment
return of the Standard & Poor's 500 Composite Stock Price Index (the "S&P 500
Index"), through investment in common stocks traded on the New York Stock
Exchange and the American Stock Exchange and in the over-the-counter markets.
The Fund generally invests in all 500 stocks of the S&P 500 Index, in
approximately the same weightings as the issues in the Index. Like the
securities in the S&P 500 Index, the Fund will hold both dividend paying and
non-dividend paying common stocks.

                                       4
<PAGE>

Active portfolio management strategies are not used in making investment
decisions for the S&P 500 Index Fund. Rather, the Fund utilizes a passive
investment management approach. The Fund may use statistical selection
techniques to determine which securities to purchase or sell to most efficiently
replicate the investment return of the S&P 500 Index.

PRINCIPAL RISKS
The S&P 500 Index Fund is subject to the risks associated with investing in U.S.
equity securities of relatively large capitalization. These risks including
market risk, event risk and political/legal risk. See "Types of Investment
Risk." The value of an investment in the Fund will fluctuate, and you may lose
money investing in the Fund.


THIS FUND MAY BE APPROPRIATE FOR:
- -  Investors looking for an investment that tends to approximate the performance
   of the general market for large-capitalization U.S. equity securities
- -  Investors who want a diverse holding of stocks within the same mutual fund
- -  Investors seeking a growth-oriented vehicle

The bar chart and table below illustrate how performance can vary and give you
an indication of the risks of investing in the Fund. The bar chart shows the
Fund's performance for each full calendar year since inception. The table shows
how the Fund's average annual returns for one year and inception to date compare
with those of the S&P 500 Index. The information assumes the reinvestment of all
dividends and distributions. Keep in mind that the Fund's past performance does
not indicate how it will perform in the future.

INTERNATIONAL EQUITY FUND

INVESTMENT OBJECTIVE AND PRINCIPAL STRATEGY
The investment objective of the International Equity Fund is to provide
long-term capital appreciation by investing primarily in equity and
equity-related securities of companies that are organized outside of the United
States or whose securities are principally traded outside of the United States.
The Fund's investments may include:


                                       5
<PAGE>

- -  Securities of companies organized in the United States but having their
   principal activities and interests outside the United States
- -  Securities denominated or quoted in foreign currency
- -  Securities issued by foreign governments or agencies or instrumentalities of
   foreign governments

The Adviser's investment strategy is to invest in the equity securities of
non-U.S. markets and companies which are believed to be undervalued based upon
decisions concerning the relative attractiveness of asset classes, the
individual international equity markets, industries across and within those
markets, other common risk factors within those markets and individual
international companies. The relative performance of foreign currencies is an
important factor in the International Equity Fund's performance. The Adviser may
manage the Fund's exposure to various currencies to take advantage of different
yield, risk and return characteristics.

The Fund generally invests in the equity markets that comprise the Morgan
Stanley Capital International Non-U.S. Equity (Free) Index (the "MSCI Index"),
and it invests primarily in the larger, more liquid securities available in
those equity markets. The Adviser will attempt to enhance the long-term return
and risk performance of the International Equity Fund relative to the MSCI Index
by deviating from the normal MSCI Index mix of country allocation and currencies
in reaction to perceived discrepancies between current market prices and
fundamental values. The Fund may sell securities when, based on their growth
potential or price, they no longer are attractive in the Adviser's opinion.

Under normal market conditions, the International Equity Fund will invest at
least 65% of its total assets in the securities of foreign issuers located (or,
in the case of the securities, traded) in countries other than the United
States.

PRINCIPAL RISKS
The International Equity Fund is subject to the general risks associated with
investing in equity securities. These risks include event risk, market risk and
political/legal risk. See "Types of Investment Risk." The International Equity
Fund is also subject to the risks that may be associated with foreign securities
and foreign currencies. These include:
- -  Currency exchange rate fluctuations
- -  Risks relating to political or economic conditions in foreign countries
- -  Potentially less stringent investor protection, disclosure standards and
   settlement procedures of foreign markets
- -  Less market liquidity

These factors could make foreign investments more volatile. The value of an
investment in the Fund will fluctuate, and you may lose money investing in the
Fund.

THIS FUND MAY BE APPROPRIATE FOR:
- -  Aggressive investors who wish to gain exposure to non-U.S. equity markets
- -  Investors who may want to diversify a balanced or equity portfolio with a
   modest allocation to non-U.S. equities

The bar chart and table below illustrate how performance can vary and give you
an indication of the risks of investing in the Fund. The bar chart shows the
Fund's performance for each full calendar year since inception. The table shows
how the Fund's average annual returns for one year and inception to date compare
with those of the MSCI Index. The information assumes the reinvestment of all
dividends and distributions. Keep in mind that the fund's past performance does
not indicate how it will perform in the future.

REIT INDEX FUND

INVESTMENT OBJECTIVE AND PRINCIPAL STRATEGY
The investment objective of the REIT Index Fund is to provide capital
appreciation and accumulation of income that corresponds to the investment
return of the Morgan Stanley REIT Index, a benchmark of U.S. real estate
investment trusts ("REITs"). The Fund seeks to achieve this objective by
investing primarily in securities of REITs comprising the Morgan Stanley REIT
Index, which are principally engaged in or related to the real estate industry,
including ownership of significant real estate assets. The Fund will invest only
in equity REITs and generally will hold dividend paying REIT securities. The
Fund will not invest directly in real estate.

Active portfolio management strategies are not used in making investment
decisions for the REIT Index Fund. Rather, the Fund utilizes a passive
investment management approach. The Fund may use statistical selection
techniques to determine which securities to purchase or sell to most efficiently
replicate the investment return of the Morgan Stanley REIT Index.

PRINCIPAL RISKS
The REIT Index Fund is subject to the general risks associated with investing in
equity securities. These risks include event risk, market risk, and
political/legal risk. See Types of Investment Risks. The REIT Index Fund also
involves real estate industry risk. In general, real estate values are affected
by a variety of factors, including:
- -  Supply and demand for properties
- -  The health of the U.S. economy and regional economies
- -  The strength of specific industries renting properties

Ultimately, a REIT's performance depends on the types and locations of the
properties it owns and how well the REIT manages its properties. REITs are also
subject to interest rate risk because of the significant amount of dividend
income they generally provide.

The value of an investment in the Fund will fluctuate, and you may lose money
investing in the Fund.


THIS FUND MAY BE APPROPRIATE FOR:
- -  Investors looking for exposure to a broad range of properties diversified
   geographically and by industry
- -  Investors primarily pursuing long-term growth and income
- -  Investors seeking to diversify their assets using an investment that may move
   independently of the overall market

The bar chart and table below illustrate how performance can vary and give you
an indication of the risks of investing in the Fund. The bar chart shows the
Fund's performance for each full calendar year since inception. The table shows
how the Fund's average annual returns for one year and

                            TYPES OF INVESTMENT RISK

CREDIT RISK
Credit risk, or default risk, refers to the risk that the issuer of a fixed
income security may default (i.e., the issuer will be unable to make timely
principal and interest payments on the security). When a security is purchased,
its anticipated yield is dependent on the timely payment by the borrower of each
interest and principal installment. Credit analysis and bond ratings take into
account the relative likelihood that such timely payment will result. Therefore,
lower-rated bonds tend to sell at higher yields than top-rated bonds of similar
maturity. Furthermore, as economic, political and business developments unfold,
lower quality bonds, which possess lower levels of protection with respect to
timely payment, usually exhibit more price fluctuation than do higher-quality
bonds of like maturity.

EVENT RISK
Event risk is the risk that the price of a security may fluctuate due to
industry or corporate developments.

INTEREST RATE RISK
Interest rate risk is the risk that changing interest rates will affect the
price of a security. This term is generally associated with bond prices, but
applies to all investments. Over time, the level of interest rates available in
the marketplace changes. As prevailing rates fall, the prices of bonds and other
securities that trade on a yield basis tend to rise. On the other hand, when
prevailing interest rates rise, bond prices generally will fall. Normally, the
longer the maturity of a fixed-income security, the greater is the price
volatility.

Conversely, the shorter the maturity, the greater is the price stability, but
generally the lower is the yield. These factors may have an effect on the
volatility of the share price of each Fund investing in debt securities. A
change in the level of interest rates will tend to cause the net asset value per
share of such Funds to change. If sustained over time, it would also have the
effect of raising or lowering the yield of these Funds.

                                       8
<PAGE>

MARKET RISK
Market risk describes the risk that the price of a security may fall due to
volatility in the marketplace. Although common stocks and other equity
securities have a history of long-term growth in value, their prices may
fluctuate dramatically in the short term in response to changes in market
conditions, interest rates and other company, industry, political and economic
developments.

POLITICAL/LEGAL RISK
Political/legal risk is the possibility of any political or legal actions
adversely affecting the value of a security.

SMALL/MID-CAPITALIZATION COMPANY RISK
Small and mid-capitalization companies often have narrower markets and more
limited managerial and financial resources than larger companies. As a result,
their performance can be more volatile and they face greater risk of business
failure.

                                 FUND EXPENSES

This section describes the fees and expenses you may pay if you buy and hold

                    ADDITIONAL INVESTMENT POLICIES AND RISKS

     Each Fund has an investment objective and related investment policies and
restrictions. Each Fund uses various investment practices to pursue its
objective. THERE IS NO GUARANTEE THAT ANY OF THE FUNDS WILL ACHIEVE ITS
INVESTMENT OBJECTIVE. You should not consider one Fund to be a complete
investment program. All of the Funds are subject to the risk of changing
economic conditions, as well as the risk in the ability of the Adviser to make
changes in the composition of the Funds in anticipation of changes in economic,
business and financial conditions. As with any security, you may suffer a loss
by investing in the Funds.

     Some investments and investment practices are described in greater detail
under "Money Market Fund Investments, Investment Practices and Restrictions" and
"Additional Investment Practices and Restrictions" in the Statement of
Additional Information.


MONEY MARKET FUND

     The Fund seeks to achieve its objective by investing in a portfolio
consisting of money market instruments, which include:

         (1) U.S. Government securities--obligations issued or guaranteed as to
         interest and principal by the U.S. Government, its agencies or
         instrumentalities. These obligations may include:
             -   instruments that are supported by the full faith and credit of
                 the United States (such as Treasury bills, notes and bonds, and
                 obligations issued by the Government National Mortgage
                 Association)
             -   instruments that are supported by the right of the issuer to
                 borrow from the Treasury (such as securities of the Federal
                 Home Loan Banks)
             -   instruments that are supported by the discretionary authority
                 of the U.S. Government to purchase the agency's obligations
                 (such as securities of the Federal National Mortgage
                 Association)
             -   instruments that are supported only by the credit of the
                 instrumentality (such as securities issued by the Federal Farm
                 Credit Banks, the Student Loan Marketing Association and the
                 Federal Home Loan Mortgage Corporation).

         (2) Certificates of deposit and time deposits issued by U.S. banks
         which are members of the Federal Deposit Insurance Corporation and have
         assets of at least $1 billion.

         (3) Repurchase agreements with (a) banks or (b) government securities
         dealers recognized as primary dealers by the Federal Reserve System,
         provided that:
             -   at the time the repurchase agreement is entered into, and
                 throughout the duration of the repurchase agreement, the
                 collateral has a market value at least equal to the value of
                 the repurchase agreements
             -   the collateral consists of U.S. Government securities or
                 instruments rated in the highest rating category by at least
                 two nationally recognized statistical rating organizations (and
                 "NRSRO") as defined under Rule 2a-7, under the Investment
                 Company Act of 1940, as amended (the "1940 Act"), or by only
                 one NRSRO if only one NRSRO has issued a rating with respect to
                 the instrument; and
             -   the maturity of the repurchase agreement does not exceed 30
                 days

         (4) Commercial paper, which consists of unsecured promissory notes
         issued by corporations to finance short-term credit needs.


     The Money Market Fund will only invest in instruments denominated in U.S.
dollars that the Adviser, under the general oversight of the Board of Trustees
of the Trust, determines present minimal credit risks and are, at the time of
acquisition, either:

         (1) rated in the highest rating category by at least two NRSROs, or by
         only one NRSRO if only one NRSRO has issued a rating with respect to
         the instrument; or

                                       17
<PAGE>

         (2) in the case of an unrated instrument, determined by the Adviser to
         be of comparable quality to the above; or

         (3) issued by an issuer that has received a rating of the type
         described in (1) above on other securities that are comparable in
         priority and security to the instrument.


     The Money Market Fund invests from time to time in U.S. dollar-denominated
foreign securities, provided that the standards outlined above are met. Foreign
money market instruments are subject to additional risks, such as the following:
- -  International economic and political developments
- -  Foreign governmental restrictions that may adversely affect the payment of
   principal or interest, foreign withholding or other taxes on interest income
- -  Difficulties in obtaining or enforcing a judgment against the issuer
- -  Expropriation or nationalization of foreign issuers
- -  The extent and quality of government regulation of financial markets and
   institutions
- -  The possible impact of interruptions in the flow of international currency
   transactions


     The Money Market Fund should be subject to less risk than any other Fund
because it invests in high-quality debt obligations that have a short time
period until maturity. The rate of return to shareholders will vary with the
general levels of interest rates applicable to the short-term debt instruments.
The rate will also be affected by changes in the Money Market Fund's operating
expenses.

     Although the Money Market Fund usually will hold securities purchased until
maturity, at which time they are redeemable at their full principal value plus
accrued interest, it may engage in short-term trading to attempt to take
advantage of yield variations in the short-term market. The Money Market Fund
also may sell portfolio securities prior to maturity based on a revised
evaluation of the issuer or to meet redemptions.

     Aon, along with its wholly-owned subsidiaries, is expected to own a
substantial percentage of the outstanding shares of the Money Market Fund. Aon
and its subsidiaries may withdraw all or any portion of their investment in the
Fund at any time. A redemption of a significant percentage of the Fund's shares,
either by Aon or its subsidiaries, may adversely affect the Fund by requiring
the Adviser to sell assets of the Fund prematurely or when it may be
disadvantageous to do so, or to hold assets in cash or cash items in
anticipation of a redemption request. However, management of the Money Market
Fund believes that the Fund and its shareholders will benefit from the
substantial investments of Aon and its subsidiaries in shares of the Fund as a
result of the economies of scale available to a larger fund.

GOVERNMENT SECURITIES FUND

     U.S. Government securities in which the Government Securities Fund may
invest include:
     (1) U.S. Treasury bills, notes and bonds; and
     (2) obligations issued or guaranteed by U.S. Government agencies and
         instrumentalities which are supported by any of the following:
         -   the full faith and credit of the U.S. Government (e.g., Government
             National Mortgage Association ("GNMA") Certificates)
         -   the right of the issuer to borrow an amount limited to a specific
             line of credit from the U.S. Treasury (e.g., debt of each of the
             Federal Home Loan Banks)
         -   the discretionary authority of the U.S. Government or GNMA to
             purchase certain financial obligations of the agency or
             instrumentality (e.g., Federal National Mortgage Association)
         -   the credit of the issuing agency or instrumentality (e.g., Federal
             Land Banks, Farmers Home Administration or Student Loan Marketing
             Association).

                                       18
<PAGE>

     No assurance can be given that the U.S. Government will provide support to
such U.S. Government sponsored agencies or instrumentalities in the future,
since it is not required to do so by law.

     The Government Securities Fund may also from time to time invest in U.S.
Government debt instruments having maturities of less than one year and in other
high quality money market instruments.


     The Government Securities Fund may invest up to 50% of its net assets in
GNMA securities. Such securities (along with certain Federal National Mortgage
Association and Federal Home Loan Corporation securities in which the Government
Securities Fund may invest) have scheduled monthly interest and principal
payments relating to mortgages in the pool that are "passed through" to
investors. GNMA and other similar pass-through securities differ from
conventional bonds in that principal is paid back to the certificate holders
over the life of the loan rather than at maturity. As a result, the Government
Securities Fund will receive scheduled monthly payments of principal and
interest on its GNMA and other similar securities. In addition, the Government
Securities Fund may receive unscheduled principal payments representing
prepayments on the underlying mortgages. All payments and unscheduled
prepayments of principal will be reinvested by the Government Securities Fund in
instruments consistent with the Fund's investment objective and investment
program. GNMA and other similar securities may not be an effective means of
"locking in" long-term interest rates due to the need for the Government
Securities Fund to reinvest scheduled and unscheduled principal payments. At the
time principal payments or prepayments are received by the Government Securities
Fund (or at the time the size of the Government Securities Fund's assets may
change materially as a result of significant net purchases or redemptions of
shares), prevailing interest rates may be higher or lower than the current yield
of GNMA and other similar pass-through securities held by the Fund.

     The portfolio turnover rate for the Government Securities Fund may be
higher than that of other mutual funds with similar investment objectives due to
the frequent transactions aimed at maximizing total return. This higher
portfolio turnover rate generates higher transaction expenses and could lead to
higher distributable net investment income or capital gains. The fund seeks to
generate gains in total return that more than offset the added transaction
expenses, but there can be no assurance that the Fund will be successful or that
total return will not be adversely affected.



ASSET ALLOCATION FUND

     The Asset Allocation Fund will invest in equity securities, long-term debt
securities and money market instruments, the proportion of each being
continuously determined by the Adviser. Total return consists of current income,
including dividends, interest and discount accruals, and realized and unrealized
capital appreciation and/or realized and unrealized capital depreciation. The
Asset Allocation Fund may invest in equity securities of domestic and foreign
issuers, including common stocks, preferred stocks, convertible securities and
warrants; debt securities of domestic and foreign issuers, including bonds,
debentures and notes; and short-term money market securities.

     Depending upon prevailing economic and market conditions, the Asset
Allocation Fund may at any given time be primarily comprised of equity
securities (including debt securities convertible into equity securities),
corporate bonds and other debt securities, short-term money market securities,
or any combination thereof. For example, during periods when the Adviser
believes that the overall return on equity securities will exceed the return on
debt securities, the Asset Allocation Fund may be fully or substantially
invested in equity securities. In contrast, the Fund may be invested primarily
in debt securities during periods when the Adviser believes that the total
return from investing in debt securities will exceed the return on equity
securities. Also, the Fund may be primarily invested in short-term money market
securities.

     At least 60% of the value of any bonds held by the Asset Allocation Fund
will be rated within the four highest grades by a nationally recognized rating
service such as Moody's Investor Services, Inc. or Standard and Poor's
Corporation. Other bonds held in the Fund may be rated below those four highest
grades, and if these lower-rated bonds were held in the Fund in significant
amounts they would increase various risks, including credit risk, event risk,
political/legal risk and market risk. However, the Fund's investment in these
lower-rated fixed-income debt securities (i.e., rated lower than Baa or BBB)
will be limited to no more than 30% of the Fund's total assets measured at

                                       19
<PAGE>

the time of purchase. The lowest rating for debt securities in which the Fund
may invest is B. Such a rating indicates that a security generally lacks the
characteristics of a desirable investment and is predominantly speculative with
respect to the issuer's capacity to pay interest and repay principal. See the
Statement of Additional Information for a complete description of ratings.

     The Asset Allocation Fund will be subject to varying levels of market risk,
event risk, interest rate risk and current income volatility. The portfolio
turnover rate for the Asset Allocation Fund may be higher than for other mutual
funds with similar investment objectives due to the frequent transactions aimed
at maximizing total return. This higher portfolio turnover rate generates higher
transaction expenses and could lead to higher distributable net investment
income or capital gains. The fund seeks to generate gains in total return that
more than offset the added transaction expenses, but there can be no assurance
the the Fund will be successful or that the total return will not be adversely
affected.

     A shareholder of the Asset Allocation Fund confers substantially more
investment discretion on the Adviser than would be the case for a shareholder
investing in a mutual fund with a more narrowly defined investment objective,
thereby enabling the Adviser to invest in a wide variety of investment
securities.

S&P 500 INDEX FUND

     Standard and Poor's Corporation ("Standard & Poor's" or "S&P"(1)) chooses
the 500 common stocks comprising the Standard & Poor's 500 Composite Stock Price
Index on the basis of market values, industry diversification and other factors.
S&P may, from time to time, add common stocks to or delete common stocks from
the S&P 500 Index.

     The Fund will attempt to keep transaction costs low and minimize portfolio
turnover.

     From time to time adjustments may be made in the Fund's holdings due to
changes in the composition or weighting of issues comprising the S&P 500 Index.

     The S&P 500 Index Fund will attempt to achieve a correlation between its
total return and that of the S&P 500 Index of at least 0.95, without taking
expenses into account. A correlation of 1.00 would indicate perfect correlation,
which would be achieved when the Fund's net asset value, including the value of
its dividends and capital gains distributions, increases or decreases in exact
proportion to changes in the S&P 500 Index. Management will monitor the Fund's
correlation to the S&P 500 Index and will attempt to minimize any "tracking
error" (i.e., the statistical measure of the difference between the investment
results of the Fund and that of the S&P 500 Index) in its investment decisions
for the Fund. However, brokerage and other transaction costs, as well as other
Fund expenses, in addition to potential tracking error, will tend to cause the
Fund's return to be lower than the return of the S&P 500 Index. There can be no
assurance as to how closely the Fund's performance will correspond to the
performance of the S&P 500 Index.

     The S&P 500 Index Fund will invest at least 65% of its total assets in
stocks and other securities included in the S&P 500 Index. In this regard, the
Fund may temporarily invest cash balances, pending withdrawals or investments,
in high quality money market instruments. The Fund will not adopt a temporary
defensive investment posture in times of generally declining stock prices, and,
therefore, investors will bear the risk of general stock market declines.

     The S&P Fund may purchase and sell exchange-traded stock index futures
contracts and may utilize certain options on stock index futures contracts in
seeking to achieve its investment objective. The S&P 500 Index Fund will
primarily use futures contracts and options to rapidly adjust exposure to the
S&P 500 Index in anticipation of investing cash balances or expected cash flows
into the Fund in appropriate common stocks or in anticipation of liquidating
appropriate common stocks to meet expected redemption requests.

The use of futures contracts and options by the Fund entails certain risks,
including the following:
- -  Possible lack of liquidity due to daily limits on price fluctuations
- -  Imperfect correlation between the futures contract and the underlying
   securities in the S&P 500 Index
- -  Potential losses in excess of the amount initially invested in the futures
   contracts themselves

investment techniques which the S&P 500 Index Fund may employ and their
associated risks is contained in the Statement of Additional Information.

     S&P's only relationship to the S&P 500 Index Fund is the licensing of

of the shares of the Fund.

     S&P does not guarantee the accuracy and/or the completeness of the S&P 500
Index or any data included therein and S&P shall have no liability for any
errors, omissions or interruptions therein. S&P makes no warranty, express or

(including lost profits), even if notified of the possibility of such damages.

INTERNATIONAL EQUITY FUND

     The International Equity Fund may invest in securities of companies
organized in the United States but having their principal activities and
interests outside the United States, securities denominated or quoted in foreign
currency ("non-dollar securities"), and securities issued by foreign governments
or agencies or instrumentalities of foreign governments.

     The International Equity Fund is intended for investors who can accept the
risks involved in investments in equity and equity-related securities of foreign
issuers and in non-dollar securities.

     The equity and equity-related securities in which the International Equity
Fund may invest are common stock and preferred stock, as well as convertible
debt obligations, convertible preferred stock and warrants or other rights to
acquire stock. The Fund also may invest in securities of foreign issuers in the
form of sponsored or unsponsored American depository receipts ("ADRs"), European
depository receipts ("EDRs") and global depository receipts ("GDRs").

     Although it may invest anywhere in the world, the International Equity
Fund's assets will be primarily invested in the equity markets included in the
MSCI Index. The MSCI Index is a market-driven, broad-based index that includes
non-U.S. equity markets. The MSCI Index is designed to provide a representative
total return for major stock exchanges located outside the United States, which
currently are located in: Japan, the United Kingdom, Germany, France, Canada,
Italy, the Netherlands, Australia, Switzerland, Spain, Hong Kong, Belgium,
Singapore, Sweden, Denmark, Norway, New Zealand, Austria, Finland and Ireland.
The composition of the MSCI Index may change over time, according to criteria
established by Morgan Stanley Capital International. From time to time, the
Adviser may substitute securities in an equivalent index when it believes that
such securities in the such other index more accurately reflect the relevant
international market.

                                       21
<PAGE>

     The normal currency allocation of the International Equity Fund is
identical to the currency mix of the MSCI Index. The Fund expects to maintain
this normal currency exposure when global currency markets are fairly priced
relative to each other and relative to the associated risks. The Fund may
actively deviate from such normal currency allocation to take advantage of, or
to protect the Fund from, risk and return characteristics of the currencies when
there is a significant deviation from their perceived fundamental value. The
Adviser determines the deviation based upon its research.

     Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, The
Netherlands, Portugal and Spain are currently members of the European Economic
and Monetary Union, also known as the EMU. The EMU is an alliance designed to
create a new, integrated financial market among the participating countries.
This alliance is based on an independent central bank, a new funds payment
system and a new currency called the Euro. Each EMU country adopted the Euro as
its currency as of January 1, 1999. The old national currencies will remain
valid until July 1, 2002.

     There is still some uncertainty regarding the impact that the Euro will
have on European capital markets. The adoption of the Euro does not reduce the
currency risk presented by fluctuations in value of the U.S. dollar to other
currencies and, in fact, currency exchange risk may be magnified. Also increased
market volatility may result. Additional risks that may result include the
unpredictable effects of the Euro on the business or financial conditions of
European issuers in which the Fund invests and the fact that European issuers
may face substantial conversion costs, which may not be accurately anticipated
and may impact issuer profitability and creditworthiness.

     On occasion the International Equity Fund may, for temporary defensive
purposes to preserve capital, hold part or all of its assets in cash, other
money market instruments of the type in which the Money Market Fund may invest,
or, subject to certain tax restrictions, foreign currencies. The International
Equity Fund also may invest up to 35% of its total assets in dollar denominated
and non-dollar denominated debt securities of foreign issuers. The Fund may, for
temporary purposes to preserve capital, hold part or all of its assets in
foreign currencies or in non-dollar securities evidencing short-term debt. To
the extent that the Fund's portfolio is invested defensively or to preserve
capital, the Fund will likely forego the opportunity to realize its investment
objective of providing long-term capital appreciation by investing primarily in
equity and equity-related securities of companies organized outside the United
States.

     The International Equity Fund may make investments or engage in investment
practices that involve special risks. These include: futures contracts and
options thereon, restricted securities and repurchase agreements. These
investment practices and attendant risks are described under "Additional
Investment Practices and Restrictions" in the Statement of Additional
Information.

     As noted above, the International Equity Fund may employ certain currency
management techniques to hedge against currency exchange rate fluctuations and
to seek to increase total return. When used to attempt to increase total return,
these management techniques are speculative. Such currency management techniques
involve risks different from those associated with investing in
dollar-denominated securities of U.S. issuers. The principal currency management
instruments utilized by the Fund are forward foreign currency exchange
contracts. To the extent that the Fund is fully invested in securities of
foreign issuers or non-dollar securities while also maintaining currency
positions, it may be exposed to greater combined risk. The Fund's net currency
positions may expose it to risks independent of its securities positions.

     Portfolio turnover will not necessarily be a limiting factor in making
changes in the portfolio of the International Equity Fund to better achieve its
investment objective. The Fund may, if the Adviser believes conditions affecting
various markets or individual issues warrant such action, make periodic
adjustments to the portfolio of the Fund. In addition, brokerage commissions on
foreign equity securities transactions are often higher than those on U.S.
equity security transactions. Accordingly, the Fund will likely have a higher
portfolio turnover rate and pay greater brokerage commissions than other equity
funds, and the Fund's total return could be adversely affected. Finally, the
Fund may have higher distributable net income or capital gains than mutual funds
with lower portfolio turnover.

REIT INDEX FUND

     The REIT Index Fund is intended for investors who can accept the risks,
described below, entailed by indirect investments in real estate.

     REITs are pooled investment vehicles that invest primarily in income
producing real estate or real estate-related loans or interests therein. REITs
are generally classified as equity REITs, mortgage REITs or a combination of
equity and mortgage REITs. Equity REITs invest the majority of their assets
directly in real property and derive income primarily from the collection of
rents. Equity REITs can also realize capital gains by selling properties that
have appreciated in value. Mortgage REITs invest the majority of their assets in
real estate mortgages and derive income from the collection of interest
payments. REITs are not taxed on income distributed to shareholders, provided
that they comply with several requirements of the Internal Revenue Code of 1986,
as amended (the "Code").

     The Morgan Stanley REIT Index is made up of the stocks of all publicly
traded equity REITs (except health care REITs) that meet certain criteria. For
example, to be included in the Index, a REIT must have a total market
capitalization of at least $75 million and have enough shares and trading volume
to be considered liquid. The REIT Index Fund invests in equity REITs only.

     As of December 31, 1998, 130 equity REITs were included in the Index. The
Index is rebalanced every calendar quarter as well as each time that a REIT is
removed from the Index because of corporate activity such as a merger,
acquisition, leveraged buyout, bankruptcy, Internal Revenue Service ("IRS")
removal of REIT status, fundamental change in business or change in shares
outstanding.

     Stocks in the Morgan Stanley REIT Index represent a broadly diversified
range of property types and regions. Property types include retail stores;
residential; office; industrial and hotels.

     As of December 31, 1998, the Index's ten largest stocks made up about 30%
of its market value.

     From time to time adjustments may be made in the Fund's holdings due to
changes in the composition or weighting of issues comprising the Morgan Stanley
REIT Index.

     The REIT Index Fund will attempt to achieve a correlation between its total
return and that of the Morgan Stanley REIT Index of at least 0.95, without
taking expenses into account. A correlation of 1.00 would indicate perfect
correlation, which would be achieved when the Fund's net asset value, including
the value of its dividends and capital gains distributions, increases or
decreases in exact proportion to changes in the Morgan Stanley REIT Index.
Management will monitor the Fund's correlation to the Morgan Stanley REIT Index
and will attempt to minimize any "tracking error" (i.e., the statistical measure
of the difference between the investment results of the Fund and that of the
Morgan Stanley REIT Index) in its investment decisions for the Fund. However,
brokerage and other transaction costs, as well as other Fund expenses, in
addition to potential tracking error, will tend to cause the Fund's return to be
lower than the return of the Morgan Stanley REIT Index. There can be no
assurance as to how closely the Fund's performance will correspond to the
performance of the Morgan Stanley REIT Index.

     The REIT Index Fund will not invest more than 35% of its total assets in
stocks and other securities not included in the Morgan Stanley REIT Index. In
this regard, the Fund may temporarily invest cash balances, pending withdrawals
or investments, in high quality money market instruments. The Fund will not
adopt a temporary defensive investment posture in times of generally declining
stock prices or prices of REITs, and, therefore, investors will bear the risk of
such general stock market declines or declines in REIT stock prices.

     The REIT Index Fund is not sponsored, sold, promoted, or endorsed by Morgan
Stanley. The Morgan Stanley REIT Index is the exclusive property of Morgan
Stanley and is a service mark of Morgan Stanley Capital International. It has
been licensed for use by the Trust.

                                       23
<PAGE>

     Although the REIT Index Fund generally seeks to invest for the long term,
it retains the right to sell securities regardless of how long they have been
held. Generally, a passively managed portfolio sells securities only to respond
to redemption requests or to adjust the number of shares held to reflect a
change in the Fund's target index.

     There are significant risks inherent in the investment objective and
policies of the REIT Index Fund. REITs in the Morgan Stanley REIT Index tend to
be medium-size and small companies; their market capitalizations generally range
from $75 million to $3 billion. Like small-capitalization stocks in general,
REIT stocks can be more volatile than--and at times will perform differently
from--the large-capitalization stocks such as those found in the S&P 500 Index.
In addition, because small-capitalization stocks are typically less liquid than
large-capitalization stocks, REIT stocks may sometimes experience greater
share-price fluctuations than the stocks of larger companies. Historically,
however, the significant amount of dividend income provided by REITs has tended
to soften the impact of this volatility.

     Because of its objective of investing in equity REITs, the REIT Index Fund
is also subject to all of the risks associated with the ownership of real
estate. These risks include:
- -  Declines in the value of real estate
- -  Adverse changes in the climate for real estate
- -  Risks related to general and local economic conditions
- -  Over-building and increased competition
- -  Increases in property taxes and operating expenses
- -  Changes in zoning laws
- -  Casualty or condemnation losses
- -  Limitations on rents
- -  Changes in neighborhood values
- -  The appeal of properties to tenants
- -  Leveraging of interests in real estate
- -  Increases in prevailing interest rates
- -  Costs resulting from cleanup of environmental problems or liability to third
   parties for damages arising from environmental problems.

     In addition to the risks discussed above, equity REITs may be affected by
changes in the value of the underlying property owned by them, are dependent
upon management skill, may not be diversified and can be subject to the risk of
investing in a single or a limited number of projects. Such REITs are also
subject to heavy cash flow dependency, defaults by borrowers, self-liquidation
and the possibility of failing to qualify for special tax treatment under
Subchapter M of the Code and to maintain an exemption under the 1940 Act.
Finally, certain REITs may be self-liquidating in that a specific term of
existence is provided for in the trust document. Such REITs run the risk of
liquidating at an economically inopportune time.




                            MANAGEMENT OF THE TRUST

management were in excess of $7 billion.

     Aon Advisors has entered into investment advisory agreements with the Aon
Funds on behalf of each of the Funds. Aon Advisors provides day-to-day portfolio
management for the Money Market Fund, the Government Securities Fund, the Asset
Allocation Fund, the S&P 500 Index Fund and the REIT Index Fund. This means that

portfolio management of the International Equity Fund.

During the fiscal year ended October 31, 1998, the Funds incurred the following
total operating expenses (including the advisory fee paid to Aon Advisors),
stated as a percentage of average daily net assets:

                                  BEFORE FEE WAIVERS     NET OF FEE WAIVERS

REIT INDEX                               0.74%                  0.24%

     Aon Advisors has agreed to reimburse the Trust for any amount by which the
total annual operating expenses exceed the following amounts, stated as a
percentage of average daily net assets:



Money Market                           1.00%

Government Securities                  1.50% to $30 million; 1.25% thereafter

REIT Index                             1.50% to $30 million; 1.25% thereafter


     During the fiscal year ended October 31, 1998, Aon Advisors was not
required to reimburse the Trust for expenses incurred in excess of maximum total
operating expenses.

     The Trust pays Aon Advisors compensation in the form of investment advisory
fees. The fees are accrued daily and paid monthly. The investment advisory fee
for each Fund is based upon the average daily net assets of such Fund (See "Net
Asset Value"), at the following annual rates:



Money Market:                          .30%.

Government Securities:                 .45% of the first $100 million; .40% of
                                       the next $100 million; .35% of the next

                                       amounts in excess of $200 million.

     Through no earlier than February 29, 2000, Aon Advisors has agreed to waive
sufficient investment advisory fees to result in a net effective annual rate of
 .05% of the average daily net assets of the S&P 500 Index Fund (.10% prior to
August 1, 1998), .10% of the average daily net assets of the Money Market Fund,
the Government Securities Fund and the REIT Index Fund, .25% of the average
daily net assets of the Asset Allocation Fund, and between .55% and .60% of the
average daily net assets of the International Equity Fund.

     During the fiscal year ended October 31, 1998, the Aon Funds paid Aon
Advisors investment advisory fees (net of fee waivers) in an amount representing
 .10%, .10%, .25%, .09%, .60% and .10% of the average daily net assets of the
Money Market Fund, Government Securities Fund, Asset Allocation Fund, S&P 500
Index Fund, International Equity Fund and the REIT Index Fund, respectively.

     Aon Funds has entered into a separate administration agreement with Aon
Securities Corporation, a wholly owned subsidiary of Aon, pursuant to which the
Aon Funds pays Aon Securities Corporation an annual fee of .05% of each Fund's
average daily net assets for administrative services.

     Aon Securities Corporation also acts as the distributor for the Aon Funds.
The Aon Funds do not pay any distribution fee to Aon Securities Corporation for
these services.

                                NET ASSET VALUE

     The net asset value per share of each Fund is determined by subtracting the
liabilities of the Fund from the value of its assets and dividing the remainder
by the number of outstanding shares of the Fund. Net asset value is calculated
for each Fund once each day that the Trust is open for business, at the close of
regular trading on the New York Stock Exchange (currently 3:00 p.m., Central
Time) on each such day, except that, in the case of the Money Market Fund, net
asset value is calculated twice each such day, once at 12:30 p.m., Central Time,
and again at the close of regular trading on the New York Stock Exchange.


     The Trust is open for business on each day that the New York Stock Exchange
is open for trading, except that shares of the Money Market Fund and the
Government Securities Fund may not be purchased or redeemed on Columbus Day or
Veterans' Day.

     Because markets in other countries may be open on certain days or at times
during which markets are closed in the

                                       27
<PAGE>

United States, the value of the International Equity Fund shares may change on
days or at times during which shareholders are not able to purchase or redeem
their shares.

     With the exception of the Money Market Fund, securities of each Fund are
valued based upon market quotations or, if not readily available, at fair value
as determined in good faith under procedures established by the Aon Funds' Board
of Trustees. See "Net Asset Value" in the Statement of Additional Information.

     The Money Market Fund's net asset value is computed using the amortized
cost method to value its portfolio securities. This method involves valuing an
instrument at cost and thereafter assuming a constant amortization to maturity
of any discount or premium regardless of the impact of fluctuating interest
rates on the market value of the instrument. A more detailed description of net
asset value computation and amortized cost method is contained in the Statement
of Additional Information.

                               PURCHASE OF SHARES

     The Aon Funds offers and sells shares of the Funds at the net asset value
per share next calculated after a purchase order is accepted. To make an initial

shares of each Fund, other than the Money Market Fund, is $1,000. The initial
minimum investment for the Money Market Fund is $10,000.

1998. The officers of Aon Funds may waive the minimum investment amounts at
their discretion.

            [investor's account number and the title of the account]

     When making an initial wire purchase, please call the transfer agent at
(800) 266-3637 with the appropriate account information before sending the wire.
Be sure to specify the name of the Fund in which you want to invest. If you are
making an initial investment by wire, you must promptly complete an Account
Application and forward it to the transfer agent. Redemption requests will not
be processed until the completed Application has been received and accepted by
the Aon Funds.

     The transfer agent accepts subsequent purchase orders at its Milwaukee
office. The Aon Funds may allow certain securities dealers or financial
institutions with which we and the Distributor have entered into agreements to
purchase shares of the Funds for next day settlement. Otherwise, the transfer
agent will not accept an order from securities dealers or financial institutions
unless the dealer or institution pays for the order in immediately available
funds wired to the transfer agent by the close of business the same day. The
transfer agent will not accept an order from other investors unless they have a
creditworthy financial institution guarantee payment in immediately available
funds wired to the transfer agent by the close of business the same day.

     Purchase orders that are received and accepted before the close of trading
on the New York Stock Exchange (currently 3:00 p.m., Central Time) (12:30 p.m.
or 3:00 p.m., Central Time, in the case of the Money Market Fund) on a business
day will be executed at the price per share next calculated as of such time.
Purchase orders received and accepted after such time will be executed at the
price per share next calculated following receipt and acceptance of the purchase
order by the transfer agent.

     The Aon Funds will not accept payment in cash for the purchase of shares.
Federal regulations require that each investor provide a certified Taxpayer
Identification Number upon opening or reopening an account. Applications without
a Taxpayer Identification Number or an indication that a Taxpayer Identification
Number has been applied for will not be accepted. If a Taxpayer Identification
Number has been applied for, the number must be provided and certified within 60
days of the date of the Application. See the Account Application for further
information about this requirement.

     In the case of the Money Market Fund, if the transfer agent receives and
accepts a purchase order by 12:30 p.m. (Central Time) on a business day, the
investor will receive the portfolio dividend declared that day. If an order is
received and accepted by the transfer agent after 12:30 p.m. (Central Time), an
investor's shares will begin to accrue dividends on the following business day.

     The Aon Funds reserve the right to reject any purchase order for any
reason.

                              REDEMPTION OF SHARES

REGULAR REDEMPTION

     You may redeem shares in any amount at their next determined net asset
value after receipt of a written redemption request by Aon Funds, P.O. Box 701,
Milwaukee, WI 53201-0701.

     Aon Funds does not consider the U.S. Postal Service or other independent
delivery services to be its agents. Therefore, deposit in the mail or with such
services, or receipt at the transfer agent's post office box, of purchase
applications or redemption requests does not constitute receipt by the transfer
agent or the Aon Funds. You should not send letters by overnight courier to the
post office box address. Except as described below under "Telephone Redemption,"
redemption requests and correspondence sent to the Aon Funds by overnight
courier must be delivered to the offices of the transfer agent at 615 E.
Michigan Street, Third Floor, Milwaukee, WI 53202.

     Redemption requests must:
- -    Be signed by each owner of the shares to be redeemed in the exact manner as
     the share account is registered
- -    State the amount of redemption
- -    Identify the shareholder account number and Taxpayer Identification Number.

     If the amount of the redemption request exceeds $25,000, or if the proceeds
are to be sent elsewhere than the address of record, each signature must be
guaranteed by an eligible signature guarantor institution. Eligible signature
guarantor institutions include commercial banks that are members of the FDIC,
trust companies, or member firms of a national securities exchange. The transfer
agent will not accept guarantees from notaries public. Guarantees must be signed
by an authorized signatory of the bank, trust company or member firm and
"Signature Guaranteed" must appear with the signature. The Aon Funds may require
additional supporting documents for redemptions made by corporations, executors,
administrators, trustees and guardians. A redemption request will not be
considered received until the transfer agent receives all required documents in
proper form.

     The Aon Funds reserves the right to make a redemption-in-kind (a payment of
portfolio securities rather than cash) if the amount you are redeeming is in
excess of the greater of (i) $250,000 or (ii) 1% of a fund's assets. Generally,
redemption-in kind is used when large redemption requests may cause harm to a
Fund and its shareholders.

TELEPHONE REDEMPTION

     You may redeem shares of the Aon Funds by telephone if you check the
appropriate box on the Account Application. Once this feature has been
requested, you may redeem by calling Investor Services at (800) 266-3637, and
providing the account name, account number, Fund name and amount of redemption.
Proceeds of shares redeemed by telephone will be mailed or wired only to your
address or bank of record as shown on the records of the transfer agent.

     If you redeem shares by telephone and request wire payment, payment of the
redemption proceeds will normally be made in federal funds on the next business
day (the same business day in the case of redemptions as of 12:30 p.m., Central
Time, from the Money Market Fund), provided the redemption order is received by
the transfer agent before the close of regular trading on the New York Stock
Exchange (currently 3:00 p.m., Central Time) (or before 12:30 p.m., Central
Time, in the case of same-day redemption from the Money Market Fund). If a
redemption order is received by the transfer agent after the close of regular
trading on the New York Stock Exchange (currently 3:00 p.m., Central Time)
(after 12:30 p.m., Central Time, in the case of the Money Market Fund), or on a
non-business day, payment for the redeemed shares will, at your request,
normally be wired in federal funds one business day later.

     As stated above, the transfer agent will wire redemption proceeds only to
the bank and account designated on the Account Application or in written
instructions subsequently received by the transfer agent, and only if your bank
is a commercial bank located within the United States. The transfer agent
currently charges a $12.00 fee for each payment of redemption proceeds made by
wire. The Aon Funds imposes the wire transfer fee directly upon redeeming
shareholders requesting wire transfers.

                                       30
<PAGE>

     In order to arrange for telephone redemptions after an account has been
opened or to change the bank account or address designated to receive redemption
proceeds, you must send a written request to Aon Funds at P.O. Box 701,
Milwaukee, WI 53201-0701. The request must be signed by each shareholder of the
account with the signatures guaranteed as described above. Further documentation
may be requested from corporations, executors, administrators, trustees and
guardians.

     The Aon Funds reserves the right to refuse a telephone redemption if Aon
Funds believes it is advisable to do so. Procedures for redeeming shares by
telephone may be changed or terminated by the Aon Funds at any time. In
addition, neither the Aon Funds nor its transfer agent will be responsible for
the authenticity of redemption instructions received by telephone. Nevertheless,
the transfer agent has established certain reasonable procedures to confirm that
instructions communicated by telephone are genuine (in the absence of such
procedures the Aon Funds or the transfer agent may be liable for any
unauthorized or fraudulent instructions). Such procedures may include requiring
forms of personal identification prior to acting upon instructions received by
telephone, providing written confirmation of such instructions or transactions
and/or tape recording telephone instructions. You would bear any losses
resulting from unauthorized telephone redemption instructions with respect to
your account.

     During periods of substantial economic or market change, telephone
redemptions may be difficult to execute. If you are unable to contact the
transfer agent by telephone, you may also redeem shares by delivering the
redemption request to the transfer agent in person or by mail as described above
under "Regular Redemption."

CHECK REDEMPTION FOR MONEY MARKET FUND

     You may request on the Account Application or by later written request that
the Money Market Fund provide to you Redemption Checks ("Checks") which may be
drawn on the Fund. Checks will be sent only to the registered owner(s) of shares
of the Money Market Fund and only to the address of record. Checks may be made
payable to the order of any person in the amount of $500 or more. Dividends are
earned on amounts drawn until the Check clears the transfer agent. When a Check
is presented to the transfer agent for payment, the transfer agent, as your
agent, will cause the Fund to redeem a sufficient number of your shares to cover
the amount of the Check. Checks will not be returned to you after clearance.
There is no charge for the use of the Checks; however, the transfer agent will
impose a $25 charge for stopping payment of a Check upon your request. You will
also be charged $25 if the transfer agent cannot honor a Check due to
insufficient funds or for any other valid reason. Because dividends on the Money
Market Fund accrue daily, Checks may not be used to close an account, as a small
balance is likely to result.

OTHER REDEMPTION INFORMATION

     Share redemption requests are effected at the net asset value next
determined after receipt of a request in proper form by the transfer agent.
Shares for which redemption requests are received by the Trust's transfer agent
in proper form before the close of regular trading on the New York Stock
Exchange (currently 3:00 p.m., Central Time) (before 12:30 p.m., Central Time,
in the case of the Money Market Fund) on a business day will not receive any
Fund dividend declared that day. If the request is received in proper form after
the close of regular trading on the New York Stock Exchange (currently 3:00
p.m., Central Time) (after 12:30 p.m., Central Time, in the case of the Money
Market Fund), the shares to be redeemed will be credited with that day's
dividend.

     Each Fund ordinarily will make payment for redeemed shares within seven
days after receipt by the transfer agent of a request in proper form, except as
may otherwise be permitted by the SEC. Payment may be delayed:
- -  For any period during which the New York Stock Exchange is closed (other than
   customary weekend or holiday closings) or trading on the New York Stock
   Exchange is restricted.
- -  For any period during which an emergency exists, as determined by the SEC,
   and it is not reasonably practicable for such Fund to dispose of its
   securities, or to determine the value of its net assets.
- -  For other periods as permitted by the SEC for the protection of the Fund's
   shareholders.

     Shares purchased by check will not be redeemed until the check has cleared,
which may take up to fifteen days. Prior to redemption, dividends on such shares
will accrue and be payable, and you will be entitled to exercise all other

                                       31
<PAGE>

rights of beneficial ownership. If you are purchasing shares by wire you must
file an Account Application before payment is made on any redemption requests
for shares purchased by wire.

     Each Fund reserves the right to redeem involuntarily, upon not less than 30
days' notice, any shareholder account which is reduced as a result of a
redemption by an investor to a value of less than $500.


                        ADDITIONAL SERVICES TO INVESTORS

AUTOMATIC INVESTMENT PROGRAM

     When opening an account, you may authorize deductions to be made from your
personal bank checking account for investment each month in shares of a Fund.
The minimum subsequent investment amounts ($100 for a Non-Money Market Fund and
$1,000 for the Money Market Fund) apply. There is no obligation to continue
automatic investment program purchases, and you, the Aon Funds or Firstar Mutual
Funds Service LLC may terminate the program at any time. To initiate this
program, please complete the Supplemental Application, which is attached to the
Application. For information on obtaining an Application, see "Purchase of
Shares."

EXCHANGE PRIVILEGE

     Shares of any of the Aon Funds which have been registered in your name for
at least 15 days may be exchanged for shares of any other Aon Funds, as long as
the shares acquired in the exchange are qualified for sale in the jurisdiction
of your residence. Before initiating an exchange, you should carefully read this
Prospectus as it relates to the new Fund in which you are considering investing.

     Under the exchange privilege, each Fund offers to exchange its shares for
shares of another Fund on the basis of relative net asset values per share. In
order to exercise an exchange without further approval of the Aon Funds, the
shares being exchanged must have a net asset value of at least $1,000 but not
more than $500,000 for each Fund except the Money Market Fund. Shares being
exchanged for shares in the Money Market Fund must have a net asset value of at
least $10,000 but not more than $500,000. (The same exceptions to the initial
minimum investment amounts apply to the minimum exchange amounts.)

     To elect the exchange privilege, you must check the appropriate box on the
Account Application. To exercise the exchange privilege, you must contact the
transfer agent in writing, or telephone the transfer agent at (800) 266-3637 and
request the exchange. You will be charged $5.00 for each telephone exchange
resulting in a redemption out of any Fund. This charge will be deducted from the
amount being exchanged.

     An exchange of shares is treated as a sale for federal income tax purposes
and, depending upon the circumstances, a short or long-term capital gain or
loss may be realized. If you have questions as to the tax consequences of an
exchange, you should consult your tax adviser.

     The exchange privilege may be modified or terminated at any time upon 60
days' prior written notice. Although you may make up to four exchanges in any
one calendar year, the Aon Funds reserves the right to limit the number of
exchanges in excess of four per year.

SYSTEMATIC WITHDRAWAL PLAN

     If you own shares having a value of $7,500 or more you may receive regular
monthly, quarterly or annual payments by arranging to redeem shares of a Fund on
a regular basis under a Systematic Withdrawal Plan (the "Withdrawal Plan").
Under the Withdrawal Plan, you can elect fixed dollar monthly, quarterly or
annual payments of at least $100 each. Under the Withdrawal Plan, you must elect
to reinvest dividends and other distributions in additional Fund shares. All
payments are made by redeeming shares, and when all the shares under the
Withdrawal Plan have been redeemed, no more payments are made. Either you or the
Aon Funds may terminate participation in the Withdrawal Plan at any time. To
initiate the Withdrawal Plan, please complete the Supplemental Application,
which is attached to the Application.

                       DIVIDENDS, DISTRIBUTIONS AND TAXES

DISTRIBUTION POLICY

     Dividends on your interest in the Money Market Fund will accrue daily and
usually be distributed to you monthly. The Government Securities Fund will
generally pay dividends from its net investment income monthly. The Asset
Allocation Fund will generally pay dividends from its net investment income
quarterly. The S&P 500 Index Fund, the International Equity Fund and the REIT
Index Fund generally pay dividends from their net investment income at least
annually. The Funds distribute any net capital gains at least annually, usually
in December.

REINVESTMENT OF DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

     Your dividends and net capital gain distributions will be automatically
reinvested in additional shares of your Fund, unless you choose otherwise. Your
other options are (1) to receive checks for these distributions, (2) to receive
checks for net investment dividends and to reinvest net capital gain
distributions in your Fund, or (3) to have the distributions automatically
invested in another of the Funds.

TAXABLE DISTRIBUTIONS

     Any distributions you receive from a Fund's net income and gains, exclusive
of net capital gains (also called "net investment income"), are taxable to you
as ordinary dividend income at your income tax rate (whether you reinvest your
distributions or take them in cash) and will be eligible for the corporate
dividends received deduction only to the extent paid out of the Fund's
qualifying dividend income. Distributions you receive from the Fund's net
long-term capital gain in excess of its net short-term capital losses (also
called "net capital gain") are generally treated as gain recognized by you from
the sale or exchange of a capital asset held for more than one year. This is
generally true no matter how long you have owned your shares and whether you
reinvest your distributions or take them in cash. You may also have to pay taxes
when you exchange, redeem or sell shares if the value of your shares has
increased above their cost basis since you bought them. However, any loss
recognized on the sale of a share held for six months or less is treated as
long-term capital loss to the extent of any net capital gain distributions made
with respect to such share.

     If you are considering buying shares of one of the Funds just prior to a
record date for a taxable distribution you should be aware that the amount of
the distribution will be taxable to you as either a dividend or net capital gain
distribution.

INFORMATION REPORTING AND BACK UP WITHHOLDING

     By law, the Aon Funds must withhold your distributions and proceeds at the
31% "backup withholding" rate if you have not provided us with complete and
correct taxpayer information such as your Social Security Number (SSN) or Tax
Identification Number (TIN) and you are not exempt from backup withholding.

YEAR-END STATEMENT

     To assist you in tax preparation, after the end of each calendar year, you
will receive a statement of the Fund's ordinary dividends and net capital gain
distributions (Form 1099). However, many of the REITs in which the REIT Index
Fund may invest do not provide complete tax information until after the calendar
year end. As a result, if you invest in the REIT Index Fund, the Aon Funds may
not be able to determine how much of the REIT Index Fund's annual distributions
are taxable to you until after the traditional January 31 deadline for issuing
the Form 1099. In this event, the Aon Funds may request permission from the IRS
for an extension and mail the Form 1099s to REIT Index Fund shareholders in
February.

                                       33
<PAGE>

     Because everyone's tax situation is unique, you should consult your tax
professional regarding potential federal, state, local, or foreign taxation of
your investment in any of the Funds.

REINVESTING OUTSTANDING CHECKS

     If you choose to have distribution checks mailed to you and either the U.S.
Postal Service is unable to deliver the check(s) to you or if the check(s)
remain outstanding for at least six months, the Funds reserve the right to
reinvest the check(s) at their then current net asset value until you notify the
Aon Funds with different instructions.


                             ADDITIONAL INFORMATION


     To date, the Aon Fund's Board of Trustees has authorized the creation of
six separate series of shares of the Trust. All consideration received by the
Trust for shares of one of the series and all assets in which such consideration
is invested belong to that series and are subject to the liabilities related
thereto. The income attributable to, and the expenses of, one series are treated
separately from those of the other series. The Trust has the ability to create,
from time to time, new series without shareholder approval which may be sold
pursuant to other offering documents.

     As of December 31, 1998, Aon, itself and through its subsidiaries and
affiliates, owned beneficially and of record 98.6%, 99.9%, 99.4%, 99.2%, 99.1%
and 99.4% of the outstanding shares of beneficial interest of the Money Market
Fund, Government Securities Fund, Asset Allocation Fund, S&P 500 Index Fund,
International Equity Fund and REIT Index Fund, respectively. Aon and its
subsidiaries may be able to cast a deciding vote on matters submitted to a vote
of shareholders, which may include proposed changes in any Fund's investment
objective and fundamental investment restrictions and in the terms of its
investment advisory agreement.

     It is possible that a Fund might become liable for any misstatement in this
Prospectus about another Fund. The Trust's Board of Trustees has considered this
factor in approving the use of this single combined Prospectus.

YEAR 2000 PREPAREDNESS

     The management services provided to the Aon Funds by the Adviser, and the
services provided by the custodian, accounting agent and transfer agent to
shareholders, in part, depend on the reasonably consistent operations of their
computer systems. Many software programs and, to a lesser extent, computer
hardware in use today cannot distinguish the year 2000 from the year 1900
because of the way dates are encoded and calculated. This design flaw may have a
negative impact on the handling of securities trades, pricing and accounting
services. The Adviser and Firstar Mutual Fund Services LLC have been actively
working on necessary changes to their computer systems to attempt to make them
year 2000 compliant in time for that event.

                              GENERAL INFORMATION

    Aon Funds (the "Trust") is an open-end management investment company formed
as a Delaware business trust on May 16, 1996 and registered under the Investment
Company Act of 1940, as amended (the "1940 Act"). The Trust currently issues six
separate series of shares (each, a "Fund" and collectively, the "Funds"), each
representing a separate portfolio of securities with its own investment
objective and policies (commonly known as a mutual fund). The Funds which are
currently offered are the Money Market Fund, the Government Securities Fund, the
Asset Allocation Fund, the S&P 500 Index Fund, the International Equity Fund and
the REIT Index Fund. The Trust issues a separate series of shares for each Fund
representing undivided beneficial interests in that Fund. An investor, by
investing in a Fund, becomes entitled to a pro rata share of all dividends and
distributions arising from the net income and capital gains on the investments
of that Fund. Likewise, an investor shares pro rata in any losses of that Fund.

    Each Fund is a separate series of the Trust and is treated as a separate
entity for certain purposes under the 1940 Act and for certain other purposes. A
shareholder of one Fund has an interest in the assets only of that Fund is not
deemed to be a shareholder of any other Fund. As described below, for certain
matters shareholders of the Trust vote together as a group; as to others they
vote separately by Fund. Each Fund bears its own expenses and other liabilities
and also a share of the Trust's general liabilities.

    All six of the Funds are diversified investment companies within the meaning
of the 1940 Act.

    The investment objective of each Fund is fundamental and may not be changed
without the approval of a majority of the outstanding shares of that Fund. In
addition, the Trust has adopted certain fundamental investment restrictions with
respect to each Fund that are enumerated in detail in this document and that may
not be changed without approval of a majority of the outstanding shares of that
Fund. A majority of the outstanding shares of a Fund means the lesser of (1) 67%
of the Fund's outstanding shares present at a meeting of shareholders if more
than 50% of the outstanding shares of the Fund are present in person or by
proxy, or (2) more than 50% of the Fund's outstanding shares. In contrast,
certain other investment policies and restrictions, also described in this
document, as well as the investment policies described in the Prospectus, are
not fundamental and may be changed by the Trust's Board of Trustees without
shareholder approval.

    Trust shares are distributed through Aon Securities Corporation ("ASC"), a
wholly-owned subsidiary of Aon Corporation, a publicly held insurance holding
company the common stock of which is listed on the New York Stock Exchange and
which, through subsidiaries, is a major provider of insurance, insurance
brokerage and related services. Aon Advisors, Inc. ("AAI"), also a wholly-owned
subsidiary of Aon Corporation, serves as investment adviser to each Fund. AAI
has engaged Brinson Partners, Inc. ("Brinson Partners") as the investment
sub-adviser to provide day-to-day portfolio management for the International
Equity Fund. (As used herein, "Adviser" shall refer to AAI and, where
applicable, Brinson Partners, or both, in their respective roles.) Aon
Corporation and its subsidiary companies may, by virtue of their shareholder
interests in any Fund at any particular date, be considered to be controlling
persons of the Trust and such Fund and may be able to cast a deciding vote on
all matters submitted to a vote of the Trust's or such Fund's shareholders.


PRIOR HISTORY

    Prior to September 3, 1996, the Trust conducted business as Aon Asset
Management Fund, Inc., a Virginia corporation. Any reference herein to the
Trust, including any financial information and performance data, relating to
such period reflects the Trust's portfolios as constituted prior to the
commencement of operations of the Trust.

    Between September 3, 1996 and February 28, 1997, each of the six Funds of
the Trust issued two classes of shares, Class C shares and Class Y shares. The
principal difference between the share classes was that Class C shares were
subject to distribution expenses of up to .25% per annum under a Rule 12b-1 Plan
applicable to such shares. The Class C shares of each of the Funds were
eliminated effective February 28, 1997 by converting such shares into Class Y
shares of the respective Funds. The conversion was effected on the basis of the
relative net asset values of the Class C shares

                                       4
<PAGE>

and the Class Y shares of the respective Funds as determined as of the date and
time of conversion. Thereafter, Class Y shares became available to any investor
who before then would have qualified to purchase either Class C or Class Y
shares, and Class Y shares became known simply as "shares". Unless otherwise
specified, all references to shares of any Fund herein relating to the period
between September 3, 1996 and February 28, 1997 refer to Class Y shares of such
Fund.


PORTFOLIO TURNOVER

The turnover rate for any Fund is calculated by dividing the lesser of purchases
or sales of Fund securities during the fiscal year by the monthly average of the
value of such Fund's securities (excluding from the computation all securities,
including options, with maturities at the time of acquisition of one year or
less). For example, a portfolio turnover rate of 100% would mean that all of a
Fund's securities (except those excluded from the calculation) were replaced
once in a period of one year. A high rate of portfolio turnover generally
involves correspondingly greater transaction expenses. Turnover rates may vary
greatly from year to year as well as within a particular year and may also be
affected by cash requirements for redemptions of a Fund's shares and by certain
requirements which the Trust must satisfy to receive certain favorable tax
treatment. Because the rate of portfolio turnover is not a limiting factor,
however, particular holdings may be sold at any time, if investment judgment or
Fund operations make a sale advisable. As a result, the annual portfolio
turnover rates in future years may exceed the percentages referred to below.

    The annual portfolio turnover rates for each of the Funds for recent fiscal
periods is set forth under "Financial Highlights" in the Prospectus. The
Government Securities Fund, Asset Allocation Fund, S&P 500 Index Fund, REIT
Index Fund and International Equity Fund generally do not trade in securities
with the goal of obtaining short-term profits, but when circumstances warrant,
securities will be sold without regard to the length of time the security has
been held.



                         MONEY MARKET FUND INVESTMENTS,
                     INVESTMENT PRACTICES AND RESTRICTIONS

    The investment objective of the Money Market Fund and the policies by which
it pursues that objective are set forth in the Prospectus. This section
describes in more detail certain securities in which the Fund may invest and
certain investment practices that it may use and augments the explanation found
in the Prospectus.


U.S. GOVERNMENT SECURITIES

    U.S. Government securities are obligations issued or guaranteed by the U.S.
Government, its agencies, or instrumentalities. Some U.S. Government securities,
such as Treasury bills, notes, and bonds (which differ only in their interest
rates, maturities and times of issuance), are supported by the full faith and
credit of the United States. Others, such as obligations issued or guaranteed by
U.S. Government agencies or instrumentalities, are supported either by (1) the
full faith and credit of the U.S. Government (such as securities of the
Government National Mortgage Association ("GNMA"), (2) the right of the issuer
to borrow from the Treasury (such as securities of the Federal Home Loan Banks),
(3) the discretionary authority of the U.S. Government to purchase the agency's
obligations (such as securities of the Federal National Mortgage Association),
or (4) only the credit of the issuer. No assurance can be given that the U.S.
Government will provide financial support to U.S. Government agencies or
instrumentalities in the future.

CERTIFICATES OF DEPOSIT AND TIME DEPOSITS

    Certificates of deposit include time deposits and negotiable certificates of
deposit. Time deposits are nonnegotiable deposits maintained in a banking
institution for a specified period of time (in no event longer than seven days)
at a stated interest rate. Certificates of deposit are certificates issued
against funds deposited in a bank for a specified period of

                                       5
<PAGE>

time. Bank obligations may be purchased only if (1) the issuing bank is a U.S.
bank with total assets of at least $1 billion, and (2) the bank is a member of
the Federal Deposit Insurance Corporation.

COMMERCIAL PAPER

    Commercial paper consists of unsecured promissory notes issued by
corporations to finance short-term credit needs. Commercial paper is issued in
bearer form with maturities generally not exceeding nine months.

    Commercial paper obligations may include variable amount master demand
notes. Variable amount master demand notes are obligations that permit the
investment of fluctuating amounts at varying interest rates pursuant to
arrangements between the issuer and a commercial bank acting as agent for the
payees of such notes. The Money Market Fund has the right to increase the amount
under the note at any time up to the full amount provided by the note agreement,
or to decrease the amount, and the borrower may prepay up to the full amount of
the note without penalty. Because variable amount master demand notes are direct
lending arrangements between the lender and borrower, it is not generally
contemplated that such instruments will be traded, and there is no secondary
market for these notes, although they are redeemable (and thus immediately
repayable by the borrower) at face value, plus accrued interest, at any time. In
connection with the master demand note arrangements, the Adviser will monitor on
an ongoing basis the earning power, cash flow and other liquidity ratios of the
issuer and the borrower's ability to pay principal and interest on demand. While
the master demand notes, as such, are not typically rated by credit rating
agencies, if not so rated the Money Market Fund may invest in them only if at
the time of an investment the issuer meets the criteria in the Prospectus for
all other issuers of instruments that the Money Market Fund may purchase.
Because master demand notes are immediately repayable by the borrower on demand,
they are considered by the Money Market Fund to have a maturity of one business
day.

REPURCHASE AGREEMENTS

    Repurchase agreements are arrangements involving the purchase of money
market instruments which the Money Market Fund is qualified to purchase, and the
Fund's simultaneous agreement to sell the same instruments back to their
original seller on demand or at a specified future date at an agreed upon price.
A repurchase agreement can be viewed as a loan made by the Fund to the seller of
the instrument, with such instrument serving as collateral for the seller's
agreement to repay the amount borrowed with interest. In effect, the repurchase
price reflects an agreed upon interest rate unrelated to the stated rate on the
purchased instrument. Such transactions afford an opportunity for the Fund to
earn a return on cash that is only temporarily available.

    In the event of the default or bankruptcy of the other party, the Fund could
experience delays in recovering its money, may realize only a partial recovery
or even no recovery, and may also incur disposition costs.

    Repurchase agreements with maturities of greater than seven days are
generally not negotiable, and therefore are not regarded as liquid investments.
Such repurchase agreements may also be subject to greater risks than repurchase
agreements of shorter maturities in that (1) the seller may experience a
decrease in credit quality during the term of the repurchase agreement and (2)
the value of the collateral may decline due to higher interest rates.

    The Money Market Fund will only enter into repurchase agreements when the
Adviser, under the general oversight of the Board of Trustees of the Trust,
determines that such agreements present minimal credit risks. For repurchase
agreements, minimal credit risk determination relates to both the quality of the
instrument serving as collateral as well as the creditworthiness of the original
seller during the time frame contemplated by the repurchase agreement.
Accordingly, as explained in the Prospectus, the Fund will only enter into
repurchase agreements with banks and primary government securities dealers which
the Adviser (under the general oversight of the Trust's Board of Trustees and
using the same criteria used to evaluate the credit risk of all instruments
considered for purchase by the Fund) determines do not present a serious risk of
becoming involved in bankruptcy proceedings within the time frame contemplated
by the agreement.

                                       6

FOREIGN SECURITIES

    The Money Market Fund may invest up to 10% of its total assets, taken at
market value at the time of acquisition, in U.S. dollar-denominated money market
instruments (including commercial paper) that are issued or guaranteed by
foreign issuers, including foreign corporations or other business organizations,
foreign governments and foreign government agencies or instrumentalities, and
foreign financial institutions. However, the Money Market Fund may invest up to
25% of its total assets in securities of foreign issues if they are either: (1)
issued, assumed or guaranteed by a foreign government or political subdivision
or instrumentality thereof, or a foreign issuer having a class of securities
listed for trading on the New York Stock Exchange, or (2) assumed or guaranteed
by domestic issuers. The Money Market Fund will only invest in foreign
securities that meet its general standards described above. Investments by the
Fund in foreign securities entail certain risks not shared by domestic
securities of the same type.

    Securities of foreign issuers, particularly nongovernmental issuers, involve
risks that are not ordinarily associated with investing in domestic issuers.
These risks include political or economic instability in the country involved,
the difficulty of predicting international trade patterns and the possibility of
imposition of exchange controls. Foreign securities may also be subject to
greater fluctuations in price than similar securities of domestic issuers. In
addition, there may be less publicly available information about a foreign
issuer than about a domestic issuer. Foreign issuers generally are not subject
to uniform accounting, auditing and financial reporting standards comparable to
those applicable to domestic issuers. In many countries, there is less
government regulation of stock exchanges, brokers and listed companies than in
the United States.

    With respect to certain foreign countries, there is a possibility of
expropriation or confiscatory taxation, or diplomatic developments which could
affect a Fund's investments in certain foreign issuers; in those situations, it
may be difficult for the Fund to obtain or to enforce a judgment against the
issuer.

LENDING PORTFOLIO SECURITIES

    In order to further the Money Market Fund's investment objective of seeking
a high level of current income, it may lend its portfolio securities to brokers,
dealers, and financial institutions. The amount of loaned securities will not
exceed 5% of the value of the Fund's assets. Securities lending activities, if
and when engaged in by the Money Market Fund, will be carried out in the manner
described and subject to the conditions described in the caption "Lending
Portfolio Securities" in the next section dealing with the Non-Money Market
Funds.

INVESTMENT RESTRICTIONS

    FUNDAMENTAL INVESTMENT RESTRICTIONS. The Money Market Fund has adopted a
number of fundamental policies restricting the investment of its assets, which
may not be changed without the affirmative vote of the holders of a majority of
the Fund's outstanding voting securities. Pursuant to the Money Market Fund's
fundamental investment restrictions, it may not:

        (a) issue senior securities (except to the extent that borrowings under
    paragraph (h) below exceeding 5% of the value of the Money Market Fund's
    total assets are deemed to constitute senior securities under the 1940 Act);

        (b) purchase real estate or any interest therein, except through the
    purchase of corporate or certain government securities (including securities
    secured by a mortgage or a leasehold interest or other interest in real
    estate); a security issued by a real estate or mortgage investment trust is
    not treated as an interest in real estate;

        (c) purchase any securities on margin (except that, subject to the
    borrowing limitation in paragraph (h) below, the Money Market Fund may
    obtain such short-term credit as may be necessary for the clearance of
    purchases and sales of portfolio securities), or make short sales of
    securities or maintain a short position;

        (d) underwrite securities of other issuers (except insofar as the Money
    Market Fund or the Trust might be

                                       7
<PAGE>

    deemed an underwriter under the Securities Act of 1933 in certain resales of
    portfolio securities held by the Fund);

        (e) invest more than 25% of the value of its total assets in the
    securities of issuers having their principal activity in any particular
    industry, other than U.S. Government Securities, as defined in Section
    2(a)(16) of the 1940 Act;

        (f) invest more than 5% of the value of the Money  Market  Fund's  total
    assets in, or invest in more than 10% of the outstanding  voting  securities
    of, any one issuer,  except that this  restriction does not apply to
    investments in U.S. Government Securities;

        (g) make loans, except that the Money Market Fund may enter into
    repurchase agreements as described above or in the Prospectus, and the Fund
    may lend its portfolio securities, but not in amounts in excess of the 5% of
    the value of its assets;

        (h) borrow money, except from banks for temporary or emergency purposes,
    including the meeting of redemption requests which might otherwise require
    the untimely disposition of securities. Borrowing in the aggregate may not
    exceed 10% of the value of the Money Market Fund's total assets at the time
    the borrowing is made, and the Fund will not make additional investments
    during any period that borrowings exceed 5% of the value of its total
    assets;

        (i) pledge, hypothecate, mortgage or transfer as security for
    indebtedness any securities held by the Money Market Fund, except in an
    amount of not more than 10% of the value of its total net assets, and then
    only to secure borrowings permitted by paragraphs (c) and (h);

        (j) enter into repurchase agreements maturing in more than seven days
    if, as a result thereof, more than 10% of the value of the Money Market
    Fund's total assets would be invested in such repurchase agreements and any
    other assets which are either illiquid or are not readily marketable;

        (k) invest in time deposits maturing in more than seven days; in
    addition, time deposits maturing in two business days to seven calendar days
    may not exceed 10% of the value of the Fund's total assets; and

        (1) purchase or sell interests in oil, gas, or other mineral exploration
    or development programs, commodities, or commodity contracts, except that
    the Money Market Fund may purchase securities of issuers which invest or
    deal in any of the above, provided such securities are money market
    instruments in which the Fund is otherwise permitted to invest.

    NON-FUNDAMENTAL RESTRICTIONS. In addition to the fundamental investment
restrictions set forth above, the Money Market Fund is subject to the following
restrictions in implementing its investment policy. These additional
restrictions are not fundamental and may be changed by the Trustees without
shareholder approval. The Fund may not:

        (1) write, purchase or sell puts, calls (other than covered call
    options) or combinations thereof;

        (2) invest in securities of foreign issuers if at the time of
    acquisition more than 10% of its total assets, taken at market value at the
    time of the investment, would be invested in such securities. However, up to
    25% of the total assets of the Money Market Fund may be invested in
    securities (a) issued, assumed or guaranteed by foreign governments, or
    political subdivisions or instrumentalities thereof, (b) assumed or
    guaranteed by domestic issuers, including Eurodollar securities, or (c)
    issued, assumed or guaranteed by foreign issuers having a class of
    securities listed for trading on the New York Stock Exchange ("NYSE");

        (3) participate on a joint (or a joint and several) basis in any trading
    account in securities (but this does not include the "bunching" of orders
    for the sale or purchase of portfolio securities with other Funds, with
    individually managed accounts, or with registered investment companies
    advised or sponsored by the Money Market Fund's investment adviser or any of
    its affiliates to reduce brokerage commissions or otherwise to achieve best
    overall execution);

                                       8
<PAGE>

        (4) alone, or together with any other Fund or Funds, make investments
    for the purpose of exercising control over, or management of, any issuer;
    and

        (5) purchase securities of other investment companies.

    COMPUTATION RULE. If a percentage restriction is adhered to at the time of
an investment, a later increase or decrease in the investment's percentage of
the value of the Money Market Fund's total assets will not constitute a
violation of the percentage restriction.


                ADDITIONAL INVESTMENT PRACTICES AND RESTRICTIONS

    The respective investment objectives of the Asset Allocation Fund, S&P 500
Index Fund, Government Securities Fund, International Equity Fund and REIT Index
Fund (the "Non-Money Market Funds"), how such Funds seek to achieve such
investment objectives and the principal investment strategies by which such
Funds will pursue their objectives are generally set forth in the Prospectus.
This section describes in more detail certain securities in which such Funds
(and in certain cases the Money Market Fund) may invest and certain investment
practices they may use and is intended to augment the description found in the
Prospectus.


WHEN-ISSUED AND DELAYED DELIVERY SECURITIES

    From time to time, in the ordinary course of business, each Fund may
purchase securities on a when-issued basis or delayed-delivery basis, i.e.,
delivery and payment can take place a month or more after the date of the
transaction. The securities so purchased are subject to market fluctuation, and
no interest accrues to the purchaser during this period. At the time a Fund
makes the commitment to purchase securities on a when-issued or delayed delivery
basis, it will record the transaction and thereafter reflect the value, each
day, of such security in determining its net asset value. At the time of
delivery of the securities, the value may be more or less than the purchase
price. Each Fund will also establish a segregated account with the Trust's
custodian bank in which it will maintain cash or cash equivalents or other
liquid Fund securities equal in value, marked to market on a daily basis, to
commitments for such when-issued or delayed-delivery securities. As a general
matter each Fund will hold less than 5% of its assets in commitments to purchase
securities on a delayed-delivery or when-issued basis and will not, under any
circumstances, purchase securities on a when-issued basis or delayed-delivery
basis if, as a result, more than 10% of its net assets would be so invested.

LOANS OF PORTFOLIO SECURITIES

    Each Non-Money Market Fund may from time to time lend securities it holds to
brokers, dealers and financial institutions, up to a maximum of 20% of its total
assets, and the Money Market Fund may so lend securities up to a maximum of 5%
of the value of its assets. This percentage may not be increased without
approval of a majority of the outstanding voting securities of the respective
Funds. Such loans will be secured by the collateral in the form of cash or U.S.
Treasury securities, which at all times during which the loan is outstanding
will be maintained in an amount at least equal to the current market value of
the loaned securities. Each Fund will continue to receive interest and dividends
on the loaned securities during the term of its loans and, in addition, will
receive either a fee from the borrower or interest earned from the securities in
which cash collateral is invested during the term of the loan. Each Fund will
also receive any gain or loss in the market value of its loaned securities.

    The right to terminate a loan of securities, subject to appropriate notice,
will be given to either party. When a loan is terminated, the borrower will
return the loaned securities to the appropriate Fund. A Fund will not have the
right to vote securities on loan, but would terminate the loan and regain the
right to vote if that were important with respect to the investment.

                                       9
<PAGE>

    Each Fund intends to limit the amount of securities lending so that the
aggregate amount of interest received attributed to securities loaned, if
considered "other income" for federal tax purposes, will not cause it to lose
its tax status as a regulated investment company.

    The primary risk involved in lending securities is that the borrower will
fail financially and not return the loaned securities at a time when collateral
is insufficient to replace the full amount of the loaned securities. The
borrower would be liable for the shortage, but a Fund would be an unsecured
creditor with respect to such shortage and might not be able to recover all or
any of it. In order to minimize this risk, the Funds will make loans of
securities only to firms that the Adviser (under the general oversight of the
Board of Trustees of the Trust) deems creditworthy.


CONVERTIBLE SECURITIES

    The Asset Allocation Fund and International Equity Fund may each invest in
convertible securities. Convertible securities may include corporate notes or
preferred stock but are ordinarily a long-term debt obligation of the issuer
convertible at a stated exchange rate into common stock of the issuer. As with
all debt securities, the market value of convertible securities tends to decline
as interest rates increase and, conversely, to increase as interest rates
decline. Convertible securities generally offer lower interest or dividend
yields than non-convertible securities of similar quality. However, when the
market price of the common stock underlying a convertible security exceeds the
conversion price, the price of the convertible security tends to reflect the
value of the underlying common stock. As the market price of the underlying
common stock declines, the convertible security tends to trade increasingly on a
yield basis, and thus may not depreciate to the same extent as the underlying
common stock. Convertible securities generally rank senior to common stock in an
issuer's capital structure and are consequently of higher quality and entail
less risk of declines in market value than the issuer's common stock. However,
the extent to which such risk is reduced depends in large measure upon the
degree to which the convertible security sells above its value as a fixed-income
security. In evaluating a convertible security, the Adviser usually gives
primary emphasis to the attractiveness of the underlying common stock. The
convertible debt securities in which these Funds may invest are subject to the
same rating criteria as each Fund's investment in non-convertible debt
securities.

WARRANTS

    The Asset Allocation Fund and the International Equity Fund may each invest
up to 5% of its total assets, calculated at the time of purchase, in warrants or
rights (other than those acquired in units or attached to other securities)
which entitle the holder to buy equity securities at a specific price for a
specific period of time. These Funds will not invest more than 2% of their total
assets, calculated at the time of purchase, in warrants or rights which are not
listed on the NYSE or American Stock Exchange. Warrants and rights have no
voting rights, receive no dividends and have no rights with respect to the
assets of the issuer.

FOREIGN INVESTMENTS AND CURRENCY

     Each of the Government Securities Fund, the Asset Allocation Fund, the S&P
500 Index Fund and the REIT Index Fund may invest up to 10% of its total assets,
taken at market value at the time of acquisition, in securities of foreign
companies that are organized outside the United States or whose securities are
principally traded outside the United States (a "foreign issuer") and in
securities denominated or quoted in foreign currency ("non-dollar securities").
In addition, each of these Funds may invest up to 25% of its total assets in
securities of foreign issuers and in non-dollar securities if certain guarantees
exist. Foreign investments will qualify as "guaranteed" if they are either: (1)
issued, assumed or guaranteed by a foreign government or political subdivision
or instrumentality thereof, or a foreign issuer having a class of securities
listed for trading on the New York Stock Exchange; or (2) assumed or guaranteed
by domestic issuers.

     The International Equity Fund may invest all of its assets in the
securities of foreign issuers and in non-dollar securities.

                                       10
<PAGE>

     FOREIGN INVESTMENTS GENERALLY AND RISKS. Investments in the securities of
foreign issuers or investments in non-dollar securities may offer potential
benefits not available from investments solely in securities of domestic issuers
or U.S. dollar-denominated securities. Such benefits may include the opportunity
to invest in foreign issuers that appear to offer better opportunity for
long-term capital appreciation or current earnings than investments in domestic
issuers, the opportunity to invest in foreign countries with economic policies
or business cycles different from those of the United States and the opportunity
to reduce fluctuations in portfolio value by taking advantage of foreign
securities markets that do not necessarily move in a manner parallel to U.S.
markets.

     Investing in non-dollar securities or in the securities of foreign issuers
involves significant risks that are not typically associated with investing in
U.S. dollar-denominated securities or in securities of domestic issuers. Such
investments may be affected by changes in currency exchange rates, changes in
foreign or U.S. laws or restrictions applicable to such investments and changes
in exchange control regulations. For example, a decline in the currency exchange
rates of foreign securities might reduce the value of certain portfolio
investments. In addition, if the exchange rate for the currency in which a Fund
receives interest payments declines against the U.S. dollar before such interest
is paid as dividends to shareholders, the Fund may have to sell portfolio
securities to obtain sufficient cash to pay such dividends

    A Non-Money Market Fund may be subject to currency exposure as a result of
or independent of its securities positions, the Fund may be affected favorably
or unfavorably by changes in currency exchange rates and in exchange control
regulations and may incur costs in connection with conversions between various
currencies.

    Since foreign issuers are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to U.S. issuers, there may be less publicly available information
about a foreign issuer than about a domestic issuer. Volume and liquidity in
most foreign securities markets are less than in the United States and
securities of many foreign issuers are less liquid and more volatile than
securities of comparable domestic issuers. Fixed commissions on foreign
securities exchanges are generally higher than negotiated commissions on U.S.
exchanges, although a Non-Money Market Fund may endeavor to achieve the most
favorable net results on its portfolio transactions. There is generally less
government supervision and regulation of securities exchanges, brokers, dealers
and listed and unlisted issuers than in the United States. Mail service between
the United States and foreign countries may be slower or less reliable than
within the United States, thus increasing the risk of delayed settlements of
portfolio transactions or loss of certificates for portfolio securities.

    Foreign investment markets also have different clearance and settlement
procedures, and in certain markets there have been times when settlements have
been unable to keep pace with the volume of transactions, making it difficult to
conduct such transactions. Such delays in settlement could result in temporary
periods when a portion of the assets of a Non-Money Market Fund is uninvested
and no return is earned on such assets. The inability of a Fund to make intended
securities purchases due to settlement problems could cause such Fund to miss
attractive investment opportunities. Inability to dispose of Fund investments
due to settlement problems could result either in losses to a Fund due to
subsequent declines in value of the portfolio securities or, if the Fund has
entered into a contract to sell the securities, could result in possible
liability to the purchaser. In addition, with respect to certain foreign
countries, there is the possibility of expropriation or confiscatory taxation,
political or social instability, or diplomatic developments which could affect a
Fund's investments in those countries. Moreover, individual foreign economies
may differ favorably or unfavorably from the U.S. economy in such respects as
growth of gross national product, rate of inflation, capital reinvestment,
resource self-sufficiency or balance of payments position.

INVESTMENTS IN ADRS, EDRS AND GDRS. Many securities of foreign issuers are
represented by ADRs, EDRs and GDRs. Each of the S&P 500 Index Fund, Government
Securities Fund, Asset Allocation Fund and International Equity Fund may invest
in ADRs, EDRs and GDRs. ADRs are certificates issued by a U.S. bank or trust
company and represent the right to receive securities of foreign issuers
deposited in a domestic bank or a foreign correspondent bank. Prices of ADRs are
quoted in U.S. dollars, and ADRs are traded in the United States on exchanges or
over-the-counter and are issued by domestic banks. ADRs do not eliminate all the
risk inherent in investing in the securities of foreign issuers. To the extent
that a Fund acquires ADRs through banks which do not have a contractual
relationship with the foreign issuer of the security underlying the ADR to issue
and service such ADR

                                       11
<PAGE>

(i.e., an unsponsored ADR), there may be an increased possibility that the Fund
would not become aware of and be able to respond to corporate actions such as
stock splits or rights offerings involving the foreign issuer in a timely
manner. In addition, the lack of information may result in inefficiencies in the
valuation of such instruments. However, by investing in ADRs rather than
directly in the stock of foreign issuers, a Fund will avoid currency risks
during the settlement period for either purchases or sales. In general, there is
a large, liquid market in the United States for ADRs quoted on a national
securities exchange or the NASD's national market system. The information
available for ADRs is subject to the accounting, auditing and financial
reporting standards of the domestic market or exchange on which they are traded,
which standards are more uniform and more exacting than those to which many
foreign issuers may be subject. The Trust generally considers ADRs to be
securities issued, assumed or guaranteed by a foreign issuer.

     EDRs and GDRs are receipts issued by Non-U.S. financial institutions
evidencing an arrangement with a non-U.S. bank similar to that for ADRs and are
designed for use in non-U.S. securities markets. EDRs are in bearer form and are
designed for trading in European securities markets. GDRs are issued in either
registered or bearer form and are designed for trading on a global basis. EDRs
and GDRs are not necessarily quoted in the same currency as the underlying
security.

INVESTMENTS IN EMERGING MARKETS. The International Equity Fund may invest in
securities of issuers located in countries with emerging economies and/or
securities markets. These countries are located in the Asia-Pacific region,
Eastern Europe, Central and South America and Africa. Political and economic
structures in many of these countries may be undergoing significant evolution
and rapid development, and such countries may lack the social, political and
economic stability characteristic of more developed countries. Certain of these
countries in the past may have failed to recognize private property rights and
have at times nationalized or expropriated the assets of private companies. As a
result, the risks of foreign investment, generally including the risks of
nationalization or expropriation of assets, may be heightened. In addition,
unanticipated political or social developments may affect the values of the
International Equity Fund's investments in those countries and the availability
to the Fund of additional investments in those countries.

     The small size and inexperience of the securities markets in certain of
these countries and the limited volume of trading in securities in these
countries may also make the International Equity Fund's investments in such
countries illiquid and more volatile than investments in Japan or most Western
European countries, and the Fund may be required to establish special custody or
other arrangements before making certain investments in these countries. There
may be little financial or accounting information available with respect to
issuers located in certain of such countries, and it may be difficult as a
result to assess the value or prospects of an investment in such issuers. The
laws of some foreign countries may limit the ability of the Fund to invest in
securities of certain issuers located in those countries.


FOREIGN CURRENCY TRANSACTIONS. Because investment in foreign issuers usually
will involve currencies of foreign countries, and because the Government
Securities Fund, the Asset Allocation Fund, the S&P 500 Index Fund, the
International Equity Fund and the REIT Index Fund may have currency exposure
independent of their securities positions, the value of the assets of these
Funds as measured in U.S. dollars may be affected by changes in foreign currency
exchange rates. To the extent that a Fund's assets consist of investments quoted
or denominated in a particular currency, the Fund's exposure to adverse
developments affecting the value of such currency will increase. The
International Equity Fund often will have substantial currency exposure both
from investments quoted or denominated in foreign currencies and from its
currency positions.

     Currency exchange rates may fluctuate significantly over short periods of
time causing, along with other factors, a Fund's net asset value to fluctuate as
well. Such exchange rates generally are determined by the forces of supply and
demand in the foreign exchange markets and the relative merits of investments in
different countries, actual or anticipated changes in interest rates and other
complex factors, as seen from an international perspective. Currency exchange
rates also can be affected unpredictably by intervention by U.S. or foreign
governments or central banks, or the failure to intervene, or by currency
controls or political developments in the U.S. or abroad. To the extent that a
substantial portion of a Fund's total assets, adjusted to reflect the Fund's net
position after giving effect to currency transactions, is denominated or quoted
in the currencies of foreign countries, the Fund will be more susceptible to the
risk of adverse economic and political developments within those countries.

                                       12
<PAGE>

     In addition to investing in securities denominated or quoted in a foreign
currency, the International Equity Fund may engage in a variety of foreign
currency management practices described below. The Fund may also use these
currency exchange techniques to manage exposure to currency risk relative to the
MSCI Index (as hereafter defined) and also in the normal course of business to
hedge against adverse changes in exchange rates in connection with purchases and
sales of securities. It also may hold foreign currency received in connection
with investments in foreign securities when, in the judgment of the Adviser, it
would be beneficial to convert such currency into U.S. dollars at a later date
based on anticipated changes in the relevant exchange rate. The Fund will incur
costs in connection with conversions between various currencies.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS. The International Equity Fund may
enter into forward foreign currency exchange contracts. A forward foreign
currency exchange contract involves an obligation to purchase or sell a specific
currency at a future date, which may be any fixed number of days from the date
of the contract agreed upon by the parties, at a price set at the time of the
contract. These contracts are traded in the interbank market conducted directly
between currency traders (usually large commercial banks) and their customers. A
forward contract generally has no deposit requirement, and no commissions are
generally charged at any stage for trades. At the maturity of a forward
contract, the Fund may either accept or make delivery of the currency specified
in the contract or, at or prior to maturity, enter into a closing purchase
transaction involving the purchase or sale of an offsetting contract. Closing
purchase transactions with respect to forward contracts are usually effected
with the currency trader who is a party to the original forward contract.

    The International Equity Fund may enter into forward foreign currency
exchange contracts in several circumstances. First, when it purchases or enters
into a fixed price contract for the purchase or sale of a security denominated
or quoted in a foreign currency, or when it anticipates the receipt in a foreign
currency of dividend or interest payments on such a security which it holds, the
Fund may desire to "lock in" the U.S. dollar price or value of the security or
the U.S. dollar equivalent of such dividend or interest payment, as the case may
be. By entering into a forward contract for the purchase or sale, for a fixed
amount of dollars, of the amount of foreign currency involved in the underlying
transactions, the Fund will attempt to protect itself against an adverse change
in the relationship between the U.S. dollar and the subject foreign currency
during the period between the date on which the security is proposed to be
purchased and the date on which the security is actually purchased, or the
period during which the security is held (including the period after sale but
prior to the conversion of the proceeds into dollars), or the period between the
declaration of the dividend or interest payment and the date on which such
payments are made or received (and converted into dollars).

    When the Adviser believes that the currency of a particular foreign country
may suffer a substantial decline against the U.S. dollar, it may enter into a
forward contract to sell, for a fixed amount of dollars, the amount of foreign
currency approximating the value of some or all of the International Equity
Fund's portfolio securities denominated in such foreign currency. The precise
matching of the forward contract amounts and the value of the securities
involved will not generally be possible because the future value of such
securities in foreign currencies will change as a consequence of market
movements in the value of those securities between the date on which the
contract is entered into and the date it matures. Using forward contracts to
protect the value of the Fund's portfolio securities against a decline in the
value of a currency does not eliminate fluctuations in the underlying prices of
the securities. It simply establishes a rate of exchange which the Fund can
achieve at some future point in time. The precise projection of short-term
currency market movements is not possible, and short-term hedging provides a
means of fixing the dollar value of only a portion of the Fund's foreign assets.

    The International Equity Fund may engage in proxy-hedging by using forward
contracts in one currency to hedge against fluctuations in the value of
securities quoted or denominated in a different currency if the Adviser
determines that there is a pattern of correlation between the two currencies.
The Fund also may purchase and sell forward contracts in cross-hedging when the
Adviser anticipates that a foreign currency contained in the Morgan Stanley
Capital International Non-U.S. Equity (Free) ("MSCI") Index will appreciate or
depreciate in value, but securities denominated or quoted in that currency do
not present attractive investment opportunities and are not held by the Fund.
The Fund may also purchase and sell forward contracts to seek to increase total
return.

                                       13
<PAGE>

    The Trust's custodian will segregate cash or liquid securities of the
International Equity Fund in an amount equal to the value of the Fund's total
assets committed to the consummation of speculative forward foreign currency
exchange contracts. If the value of the securities segregated declines,
additional cash or liquid securities will be segregated on a daily basis so that
the value of the account will equal the amount of the Fund's commitments with
respect to such contracts. The segregated assets will be marked-to-market on a
daily basis. Although the contracts are not presently regulated by the Commodity
Futures Trading Commission ("CFTC"), the CFTC may in the future assert authority
to regulate these contracts. In such event, the Fund's ability to utilize
forward foreign currency exchange contracts may be restricted.

    While the International Equity Fund will enter into forward contracts to
reduce currency exchange rate risks, transactions in such contracts involve
certain other risks. Therefore, while the Fund may benefit from such
transactions, unanticipated changes in currency prices may result in a poorer
overall performance for the Fund than if it had not engaged in any such
transactions. Moreover, there may be imperfect correlation between the Fund's
portfolio holdings of securities quoted or denominated in a particular currency
and forward contracts entered into by the Fund. Such imperfect correlation may
cause the Fund to sustain losses that will prevent the Fund from achieving a
complete hedge or expose the Fund to risk of foreign exchange loss.

    Forward contracts are subject to the risk that the counterparty to such
contract will default on its obligations. Since a forward foreign exchange
currency contract is not guaranteed by an exchange or clearinghouse, a default
on the contract would deprive the Fund of unrealized profits, the benefits of a
currency hedge and may force the Fund to cover its purchase or sale commitments,
if any, at the current market price causing the Fund to incur additional
transaction costs.

WRITING AND PURCHASING CURRENCY CALL AND PUT OPTIONS. The International Equity
Fund may write (i.e., sell) covered put and call options and purchase put and
call options on foreign currencies for the purpose of protecting against
declines in the U.S. dollar value of portfolio securities and against increases
in the dollar cost of securities to be acquired. The Fund also may use options
on currency to proxy-hedge, which involves writing or purchasing options on one
currency to hedge against changes in exchange rates for a different currency, if
the Adviser determines that there is a pattern of correlation between the values
of the currencies. In addition, the Fund may purchase call or put options on a
currency to seek to increase total return when the Adviser anticipates that the
foreign currency will appreciate or depreciate in value, but securities
denominated or quoted in that currency do not present attractive opportunities
and are not held by the Fund. When purchased or sold to increase total return,
options on currencies are considered speculative.

    A call option written by the International Equity Fund obligates the Fund to
sell specified currency to the holder of the option at a specified price at any
time before the expiration date. A put option written by the Fund would obligate
the Fund to purchase specified currency from the option holder at a specified
price at any time before the expiration date. The writing of currency options
involves a risk that the Fund will, upon exercise of the option, be required to
sell currency subject to a call at a price that is less than the currency's
market value or be required to purchase currency subject to a put at a price
that exceeds the currency's market value.

    The International Equity Fund may terminate its obligations under a call or
put option by purchasing an option identical to the one it has written. Such
purchases are referred to as "closing purchase transactions." The Fund is also
able to enter into closing sale transactions in order to realize gains or
minimize losses on options purchased by it.

    The International Equity Fund would normally purchase call options in
anticipation of an increase in the U.S. dollar value of currency in which
securities to be acquired by the Fund are quoted or denominated. The purchase of
a call option would entitle the Fund, in return for the premium paid, to
purchase a specified currency at a specified price during the option period. The
Fund would ordinarily realize a gain if, during the option period, the value of
such 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 International Equity Fund would normally purchase put options in
anticipation of a decline in the dollar value of the currency in which
securities in its portfolio are quoted or denominated ("protective puts"). The
purchase of a put option would entitle the Fund, in exchange for the premium
paid, to sell a specified currency at a specified price during

                                       14
<PAGE>

the option period. The purchase of protective puts is designed merely to offset
or hedge against a decline in the dollar value of the Fund's portfolio
securities due to currency exchange rate fluctuations. The Fund would ordinarily
realize a gain if, during the option period, the value of the underlying
currency decreased below the exercise price sufficiently to more than 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
protective put options would tend to be offset by countervailing changes in the
value of the underlying currency.

    In addition to using options for the hedging purposes described above, the
International Equity Fund may use options on the currencies to seek to increase
total return. It may write covered put and call options on any currency in order
to realize greater income than would be realized on portfolio securities
transactions alone. However, in writing covered call options for additional
income, the Fund may forgo the opportunity to profit from an increase in the
market value of the underlying currency. Also, when writing put options, the
Fund accepts, in return for the option premium, the risk that it may be required
to purchase the underlying currency at a price in excess of the currency's
market value at the time of purchase.

    The International Equity Fund would normally purchase call options to seek
to increase total return in anticipation of an increase in the market value of a
currency. It would ordinarily realize a gain if, during the option period, the
value of such 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. Put options may be purchased by the
Fund for the purpose of benefiting from a decline in the value of currencies
which it does not own. It would ordinarily realize a gain if, during the option
period, the value of the underlying currency decreased below the exercise price
sufficiently to more than cover the premium and transaction costs. Otherwise, it
would realize either no gain or a loss on the purchase of the put option.

SPECIAL RISKS ASSOCIATED WITH OPTIONS ON CURRENCY. Options on foreign currencies
to be written or purchased by the Fund will be traded on U.S. or foreign
exchanges or over-the-counter. An exchange traded options position may be closed
out only on an options exchange which provides a market for an option of the
same series. Although the International Equity Fund will generally purchase or
write only those options for which there appears to be an active secondary
market, there is no assurance that a liquid market on an exchange will exist for
any particular option, or at any particular time. For some options no market on
an exchange may exist. In such event, it might not be possible to effect closing
transactions in particular options, with the result that a Fund would have to
exercise its options in order to realize any profit and would incur transaction
costs upon the sale of underlying securities pursuant to the exercise of put
options. If the Fund as a covered call option writer is unable to effect a
closing purchase transaction in a market, it may not be able to sell the
underlying currency (or security quoted or denominated in that currency) until
the option expires or it delivers the underlying currency upon exercise.

    There is no assurance that higher than anticipated trading activity or other
unforeseen events might not, at times, render certain of the facilities of the
Options Clearing Corporation or other clearing agency inadequate, and thereby
result in the institution by an exchange of special procedures which may
interfere with the timely execution of customers' orders.

    The International Equity Fund may purchase and write over-the-counter
options to the extent consistent with its limitation on investments in illiquid
investments. Trading in over-the-counter options is subject to the risk that the
other party will be unable or unwilling to perform under or close out options
purchased or written by the Fund.

CURRENCY SWAPS. The International Equity Fund may enter into currency swaps for
both hedging purposes and to seek to increase total return. Currency swaps
involve the exchange by the Fund with another party of their respective rights
to make or receive payments in specified currencies. Since currency swaps are
individually negotiated, the Fund is expected to achieve an acceptable degree of
correlation between its portfolio investments and its currency swap positions
entered into for hedging purposes. Currency swaps usually involve the delivery
of the entire principal value of one designated currency in exchange for the
other designated currency. Therefore, the entire principal value of a currency
swap is subject to the risk that the other party to the swap will default on its
contractual delivery obligations. To the extent that swaps are entered into for
good faith hedging purposes (or are offset by a segregated account as

                                       15
<PAGE>

described below), the Trust and the Adviser believe that swaps do not constitute
senior securities as defined in the 1940 Act and, accordingly, will not treat
them as being subject to the Fund's borrowing restrictions. The net amount of
the excess, if any, of the Fund's obligations over its entitlement with respect
to each currency swap will be accrued on a daily basis and an amount of cash or
liquid securities having an aggregate net asset value at least equal to such
accrued excess will be maintained in a segregated account by the Trust's
custodian. The Fund will not enter into any currency swap unless the credit
quality of the unsecured senior debt or the claims-paying ability of the other
party thereto is considered to be investment grade by the Adviser. If there is a
default by the other party to such a transaction, the Trust will have
contractual remedies pursuant to the agreement applicable to the transaction.
The swap market has grown substantially in recent years with a large number of
banks and investment banking firms acting both as principals and as agents
utilizing standardized swap documentation. As a result, the swap market has
become relatively liquid in comparison with the markets for other similar
instruments which are traded in the interbank market. Nevertheless, the staff of
the Securities and Exchange Commission ("SEC") takes the position that currency
swaps are illiquid investments subject to the Fund's limitation on such
investments.

         The use of currency swaps is a highly specialized activity which
involves investment techniques and risks different from those associated with
ordinary portfolio securities transactions. If the Adviser is incorrect in its
forecasts of market values and currency exchange rates, the investment
performance of the International Equity Fund would be less favorable than it
would have been if swaps were not used.


OPTIONS ON SECURITIES AND SECURITIES INDICES

    The Government Securities, S&P 500 Index, International Equity and REIT
Index Funds may write exchange-traded covered call and put options on or
relating to specific securities in order to earn additional income. The Asset
Allocation Fund may write covered call options on its portfolio securities in
amounts up to 10% of its total assets in order to earn additional income or to
minimize or hedge against anticipated declines in the value of those securities.
All call options written by these Funds are covered, which means that the Fund
will own the securities subject to the option as long as the option is
outstanding. All put options written by these Funds are covered, which means
that the Fund has deposited with the Trust's custodian cash or liquid securities
with a value at least equal to the exercise price of the option. Call and put
options written by a Fund may also be covered to the extent that the Fund's
liabilities under such options are offset by its rights under call or put
options purchased by the Fund (e.g. closing purchase transactions) and call
options written by a Fund may also be covered by depositing cash or liquid
securities with the Trust's custodian in the same manner as written puts are
covered.

    Through the writing of a covered call option, a Fund receives premium income
but obligates itself to sell to the purchaser of such an option the particular
security underlying the option at a specified price at any time prior to the
expiration of the option period, regardless of the market value of the security
during this period. Through the writing of a covered put option, a Fund receives
premium income but obligates itself to purchase a particular security underlying
the option at a specified price at any time prior to the expiration of the
option period, regardless of market value during the option period.

    The Government Securities, S&P 500 Index, International Equity and REIT
Index Funds may each also purchase exchange-traded call and put options with
respect to securities. These Funds may each purchase put options for defensive
purposes in order to protect against an anticipated decline in the value of
their portfolio securities. As the holder of a put option with respect to
individual securities, each has the right to sell the securities underlying the
option and to receive a cash payment at the exercise price at any time during
the option period. These Funds may each purchase call options on individual
securities and in order to take advantage of anticipated increases in the price
of those securities by purchasing the right to acquire the securities underlying
the option. As the holder of a call option with respect to individual
securities, the Funds obtain the right to purchase the underlying securities at
the exercise price at any time during the option period.

    The S&P 500 Index, International Equity and REIT Index Funds may each, in
accordance with its investment objective and investment program, also write
exchange-traded covered call and put options on stock indices. These

                                       16
<PAGE>

Funds may write such options for the same purposes as each may engage in such
transactions with respect to individual portfolio securities, that is, to
generate additional income or as a hedging technique to minimize anticipated
declines in the value of the Fund's securities. In economic effect, a stock
index call or put option is similar to an option on a particular security,
except that the value of the option depends on the weighted value of the group
of securities comprising the index, rather than a particular security, and
settlements are made in cash rather than by delivery of a particular security.

    If a Fund writes an option which expires unexercised or is closed out by
such Fund at a profit, it will retain the premium received for the option, which
will represent a capital gain to the Fund. If the price of the underlying
security moves adversely to the Fund's position, the option may be exercised and
the Fund, as the writer of the option, will be required to sell or purchase the
underlying security at a disadvantageous price, which may only be partially
offset by the amount of premium received.

    When a Fund writes an option on an index, and the underlying index moves
adversely to its position, the option may be exercised. Upon such exercise, the
Fund, as the writer of the option, will be required to pay in cash an amount
equal to the difference between the exercise settlement value of the underlying
index and the exercise price of the option, multiplied by a specified index
"multiplier."

    Call or put options on a stock index may be written at an exercise or
"strike" price which is either below or above the current value of the index. If
the exercise price at the time of writing the option is below the current value
of the index for a call option or above the current value of the index for a put
option, the option is considered to be "in the money." In such a case, a Fund
will cover such options written by segregating with its custodian as collateral
cash or liquid securities equal in value to the amount by which the option
written is in the money, times the multiplier, times the number of contracts.

    Stock indices for which options are currently traded include the S&P 500
Index, Value Line Index, National OTC Index, Major Market Index, and NYSE Beta
Index. The Funds may also use options on such other indices as may now or in the
future be available.

    The S&P 500 Index, International Equity and REIT Index Funds may also
purchase put or call options on securities indices in order to (1) hedge against
anticipated changes in stock prices generally that may adversely affect the
prices of securities that they intend to purchase at a later date, (2) hedge
their investments against an anticipated decline in value, or (3) attempt to
reduce the risk of missing a general market advance. In the event that the
anticipated changes in stock prices occur, these Funds may be able to offset the
resulting adverse effect, in whole or in part, through the options purchased.

     The effectiveness of hedging activities of the S&P 500 Index Fund, the
International Equity Fund and the REIT Index Fund through the writing or
purchase of stock index options will depend upon the extent to which price
movements in the Fund's holdings being hedged correlate with price movements in
the selected stock index. Perfect correlation may not be possible because the
securities held or to be acquired by the Fund may not exactly match the
composition of the stock index on which options are purchased or written.

    The premium paid for a put or call option plus any transaction costs will
reduce the benefit, if any, realized by a Fund upon exercise or liquidation of
the option, and, unless the price of the underlying securities index changes
sufficiently, the option may expire without value to the Fund. To close option
positions purchased by it, the S&P 500 Index, International Equity and REIT
Index Funds may sell put or call options identical to options previously
purchased, which could result in a net gain or loss depending on whether the
amount received on the sale, less all transaction costs, is more or less than
the premium paid on the put or call option purchased.

    All the Non-Money Market Funds may use options traded on a national
securities exchange. Only the Government Securities Fund, the International
Equity Fund and the REIT Index Fund, however, may write and purchase
over-the-counter (i.e., unlisted) options. Options traded in the
over-the-counter market may not be as actively traded as those on an exchange.
Accordingly, it may be more difficult to value such options. In addition, it may
be more difficult to enter

                                       17
<PAGE>

into closing transactions with respect to options traded over-the-counter. In
this regard, each of the Government Securities Fund, the International Equity
Fund and the REIT Index Fund may enter into contracts with the primary dealers
with which it writes over-the-counter options. Such contracts, if entered into,
will provide that each such Fund has the absolute right to repurchase an option
it writes at any time at a repurchase price which represents the fair market
value of such option, as determined in good faith through negotiations between
the parties, but which in no event will exceed a price determined pursuant to a
formula contained in the contract. Although the specific details of the formula
may vary between contracts with different primary dealers, the formula will
generally be based on a multiple of the premium received by the Fund, plus the
amount, if any, of the option's intrinsic value (i.e., the amount the option is
"in-the-money"). The formula will also include a factor to account for the
difference between the price of the security and the strike price of the option
if the option is written "out-of-the-money." Although the specific details of
the formula may vary with different primary dealers, each contract will provide
a formula to determine the maximum price at which the Fund can repurchase the
option at any time. Except for the amount of this formula price less the amount
by which an over-the-counter option is "in-the-money," this option will
generally be considered illiquid securities. The Adviser has established
standards of creditworthiness for these primary dealers.

     As to all options, if the Adviser's forecasts regarding movements in
securities prices or interest rates are incorrect, a Fund's investment results
might have been more favorable had a transaction not been effected. Because of
these risks, the use of "options" related investment practices requires special
skills in addition to those needed to select portfolio securities and there can
be no assurances that the Adviser will be able to employ these practices
successfully.

FINANCIAL FUTURES CONTRACTS

    The Government Securities, S&P 500 Index, International Equity and REIT
Index Funds, each in accordance with its investment objective, investment
program, policies, and restrictions, may purchase and sell exchange-traded
financial futures contracts as a hedge to protect against anticipated changes in
prevailing interest rates or overall stock prices, or to efficiently and in a
less costly manner implement either increases or decreases in exposure to the
equity or government bond markets. Likewise, the International Equity Fund may
purchase and sell exchange-traded currency futures contracts as a hedge to
protect against anticipated adverse changes in currency exchange rates. All of
these Funds also may purchase and sell exchange-traded financial futures
contracts to earn additional income or otherwise seek to increase total return.

         If expectations regarding movements in securities prices or interest
rates are incorrect, a Fund might have experienced better investment results
without hedging. The use of futures contracts, as well as options on futures
contracts discussed below, requires special skills in addition to those needed
to select portfolio securities.

     A financial futures contract is an agreement to buy or sell a security or
currency (or deliver a final cash settlement price, in the case of a contract
relating to an index or otherwise not calling for physical delivery of a
specified security) for a set price in the future. Exchange-traded futures
contracts, to the extent that they are traded on an exchange or board of trade
located in the U.S. are traded on or subject to the rules of the boards of trade
which have been designated "contracts markets" by the CFTC. Financial futures
contracts consist of interest rate futures contracts, stock index futures
contracts and currency futures contracts.

    An interest rate futures contract binds the seller either to deliver to the
purchaser on a specified future date a specified quantity of one of several
listed financial instruments, against payment of a settlement price specified in
the contract, or the parties to settle in cash based upon the interest rate or
rate index at the expiration of the contract. A public market currently exists
for futures contracts the prices of which are related to interest rates on,
among other instruments, long-term U.S. Treasury Bonds, three-month U.S.
Treasury Bills, U.S. Treasury Notes and three month Eurodollars.

    Stock index futures contracts bind purchaser and seller to deliver, at a
future date specified in the contract, a cash amount equal to a multiple of the
difference between the value of a specified stock index on that date and the
settlement price specified by the contract. That is, the seller of the futures
contract must pay and the purchaser would receive a multiple of any excess of
the value of the index over the settlement price, and conversely, the purchaser
must pay and the

                                       18
<PAGE>

seller would receive a multiple of any excess of the settlement price over the
value of the index. A public market currently exists for stock index futures
contracts based on, among other indices, the S&P 500 Index, the New York Stock
Exchange Composite Index, the Value Line Stock Index and the Dow Jones
Industrial Index. It is expected that financial instruments related to
broad-based indices, in addition to those for which futures contracts are
currently traded, will in the future be the subject of publicly-traded futures
contracts. Each Non-Money Market Fund (except the Asset Allocation Fund) may use
those indices which are appropriate to its hedging strategies.

    A currency futures contract is a contract to purchase or sell a specific
amount of foreign currency at a future time at a fixed price.

     To hedge against the possibility that increases in interest rates or other
factors may result in a general decline in prices of securities owned by it, the
Government Securities Fund and the REIT Index Fund may sell interest rate
futures contracts. To hedge against the possibility of a general decline in the
prices of securities owned by it, the S&P 500 Index Fund, the International
Equity Fund and the REIT Index Fund may sell stock index futures contracts. To
hedge against the possibility of an adverse change in currency exchange rates,
the International Equity Fund may sell currency futures contracts. Assuming that
any decline in the securities or currency being hedged is accompanied by a
decline in the debt instrument, interest rate, stock index or currency chosen as
a hedge, the sale of a futures contract on that debt instrument, interest rate,
stock index or currency may generate gains that can wholly or partially offset
any decline in the value of the Fund's securities or currency exposure which
have been hedged.

     To hedge against the possibility of lower long-term interest rates and
likely concomitant increase in prices of securities to be purchased by it, the
Government Securities Fund and the REIT Index Fund may purchase interest rate
futures contracts. Likewise, to hedge against increases in equity prices, the
S&P 500 Index Fund, the International Equity Fund and the REIT Index Fund may
purchase stock index futures contracts. To hedge against the possibility of an
adverse change in currency exchange rates, the International Equity Fund may
purchase currency futures contracts. For these Funds, such a strategy is
intended to secure a position in the futures market intended to approximate the
economic equivalent of a position in the securities market. When used as hedges,
the Funds will purchase appropriate financial futures contracts only when each
intends to purchase the underlying securities that may be affected by such
decreases in interest rates or increases in equity prices or decline in value of
the dollar versus the currency in which the security to be purchased is
denominated (as the case may be) and will purchase such financial futures
contracts in approximately the amount being hedged. When used as hedges, the
Adviser expects that purchases of the underlying securities will, in fact, be
made a substantial majority of the time.

     Each of the Government Securities Fund, the S&P 500 Index Fund, the
International Equity Fund and the REIT Index Fund may purchase and sell
exchange-traded financial futures contracts for non-hedging purposes such as
seeking additional income or otherwise seeking to increase total return.

    Positions taken in the futures markets are not normally held until delivery
or cash settlement is required, but instead are liquidated through offsetting
transactions which may result in a gain or a loss. While futures positions taken
by a Non-Money Market Fund (except the Asset Allocation Fund) are usually
liquidated in this manner, a Fund may instead make or take delivery of
underlying securities whenever it appears economically advantageous to do so. A
clearing organization associated with the relevant exchange assumes
responsibility for closing out transactions and guarantees that, as between the
clearing members of the exchange, the sale and purchase obligations will be
performed with regard to all positions that remain open at the termination of
the contract.

    When financial futures contracts are entered into by a Non-Money Market Fund
(except the Asset Allocation Fund), either as the purchaser or the seller of
such contracts, the Fund is required to deposit with its custodian in a
segregated account in the name of its future commission merchant ("FCM") an
initial margin of cash or U.S. Treasury bills equal to as much as 5% to 10% or
more of the contract settlement price. The nature of initial margin requirements
in futures transactions differs from traditional margin payments made in
securities transactions in that initial margins for financial futures contracts
do not involve the borrowing of funds by the customer to finance the
transaction. Instead, a customer's initial margin on a financial futures
contract represents a good faith deposit securing the customer's contractual
obligations under the financial futures contract. The initial margin deposit is
returned, assuming these obligations have

                                       19
<PAGE>

been met, when the financial futures contract is terminated. In addition,
subsequent payments to and from the FCM, called "variation margin," are made on
a daily basis as the price of the underlying security or stock index or currency
fluctuates reflecting the change in value in the long (purchase) or short (sale)
positions in the financial futures contract, a process known as "marking to
market."

     None of the Funds will enter into any speculative financial futures
contract (or purchase any option thereon) if, immediately thereafter, the total
amount of its assets required to be on deposit as initial margin to secure its
obligations under such open futures contracts, plus the amount of premiums paid
by the Fund for outstanding options to purchase such futures contracts (less any
in-the-money amount at the time of purchase) would exceed 5% of the market value
of the Fund's total assets (after taking into account unrealized profits and
losses on any such futures contracts or options it has entered into).

    Financial future contracts generally are not entered into to acquire the
underlying asset and generally are not held to term. Prior to the contract
settlement date, a Non-Money Market Fund will normally close all futures
positions by entering into an off-setting transaction which operates to cancel
the position held, and which usually results in a profit or loss.

OPTIONS ON FINANCIAL FUTURES CONTRACTS

    The Government Securities, S&P 500 Index, International Equity and REIT
Index Funds may also purchase call and put options on financial futures
contracts and write covered call options on financial futures contracts of the
types which the particular Fund is authorized to enter into. The S&P 500 Index
and REIT Index Funds also may write covered put options on stock index futures
contracts. Covered put and call options on futures contracts will be covered in
the same manner as covered options on securities and securities indices.

    Options on financial futures contracts, to the extent traded on an exchange
or board of trade located in the U.S., are traded on contract markets that are
licensed and regulated by the CFTC. A call option on a financial futures
contract gives the purchaser the right, in return for the premium paid, to
purchase a financial futures contract (similar to a "long" position) at a
specified exercise price at any time before the option expires. A put option
gives the purchaser the right, in return for the premium paid, to sell a
financial futures contract (similar to a "short" position on a financial futures
contract), for a specified exercise price, at any time before the option
expires. The Funds, as described above, may invest in such options for the same
hedging purposes as they may each purchase or sell financial futures contracts
or in order to earn additional income or otherwise seek to increase total
return.

     The S&P 500 Index Fund and the REIT Index Fund may seek to close out (at
its market price on the relevant market) such put option before the option has
expired. If the market is not liquid for that option, however, the Fund must
continue to be prepared to pay the strike price while the option remains
outstanding, regardless of price changes, and must continue to set aside liquid
assets to cover this position.

    Unlike entering into a financial futures contract itself, purchasing options
on financial futures contracts allows a buyer to decline to exercise the option,
thereby avoiding any loss beyond foregoing the purchase price (or "premium")
paid for the options and transaction costs. Whether, in order to achieve a
particular objective, a Fund enters into a financial futures contract, on the
one hand, or an option contract on a financial futures contract, on the other,
will depend on all the circumstances, including the relative costs, liquidity,
availability and capital requirements of such financial futures and options
contracts. Each Fund will consider the relative risks involved, which may be
quite different. These factors, among others, will be considered in light of
market conditions and the particular objective to be achieved.



CERTAIN ADDITIONAL RISKS OF OPTIONS AND FINANCIAL FUTURES CONTRACTS

    In addition to the risks described in the Prospectus, the use of options and
financial futures contracts may entail the following risks. First, although such
instruments when used by a Fund are intended to correlate with the Fund's
portfolio

                                       20
<PAGE>

securities, in many cases the options or financial futures contracts used may be
based on securities or currencies which, or stock indices the components of
which, are not identical to the portfolio securities owned or intended to be
acquired by the Fund. Second, due to supply and demand imbalances and other
market factors, the price movements of financial futures contracts, options
thereon, and stock index options may not necessarily correspond exactly to the
price movements of the securities, currencies or stock indices on which such
instruments are based. Accordingly, there is a risk that a Fund's transactions
in those instruments will not in fact offset the impact on the Fund of adverse
market developments in the manner or to the extent contemplated or that such
transactions will result in losses to the Fund which are not offset by gains
with respect to corresponding portfolio securities owned or to be purchased by
that Fund.

    To some extent, careful management of hedging activities can minimize these
risks. For example, where price movements in a financial futures or option
contract are expected to be less volatile than price movements in the related
portfolio securities owned or intended to be acquired by a Fund, it may, in
order to compensate for this difference, use an amount of financial futures or
option contracts which is greater than the amount of such portfolio securities.
Similarly, where the price movement of a financial futures or option contract is
anticipated to be more volatile, a Fund may use an amount of such contract which
is smaller than the amount of portfolio securities to which such contracts
relate.

    The risk that the hedging technique used will not actually or entirely
offset an adverse change in the value of a Fund's securities is particularly
relevant to financial futures contracts and options written on stock indices. A
Fund entering into a futures purchase contract potentially could lose any or all
of an amount equal to the contract's settlement price multiplied by the
contract's multiplier. In entering into a futures sale contract, a Fund could
potentially lose an amount equal to the excess of the contract's value (marked
to market daily) over the contract's settlement price multiplied by the
contract's multiplier. In writing options on stock indices, a Fund could
potentially lose a sum equal to the excess of the value of the index (marked to
market daily) over the exercise price or the excess of the exercise price over
the value of the index. In addition, because financial futures contracts require
delivery at a future date of either a specified security or an amount of cash
equal to a multiple of the difference between the value of a specified stock
index on that date and the settlement price, an algebraic relationship exists
between any price movement in the underlying security or index and the potential
cost of settlement to a Fund. A small increase or decrease in the value of the
underlying security or stock index can, therefore, result in a much greater loss
to the Fund.

    Stock index call options written also pose another risk as hedging tools.
Because exercises of stock index options are settled in cash, there is an
inherent timing risk that the value of a Fund's securities "covering" a stock
index call option written by it may decline during the time between exercise of
the option by the option holder and notice to the Fund of such exercise (usually
one day or more), thereby requiring the Fund to use additional assets to settle
the transaction. This risk is not present in the case of covered call options on
individual securities, which are settled by delivery of the actual securities.

    Although the Funds intend to establish positions in these instruments only
when there appears to be an active market, there is no assurance that a liquid
market for such instruments will exist when they seek to "close out" (i.e.
terminate) a particular financial futures contract or option position. This is
particularly relevant for over-the-counter options. Trading in such instruments
could be interrupted, for example, because of a lack of either buyers or
sellers. In addition, the futures and options exchanges may suspend trading
after the price of such instruments has risen or fallen more than the maximum
amount specified by the exchange. Exercise of options could also be restricted
or delayed because of regulatory restrictions or other factors. A Fund may be
able, by adjusting investment strategy in the cash or other contract markets, to
offset to some extent any adverse effects of being unable to liquidate a hedge
position. Nevertheless, in some cases, a Fund may experience losses as a result
of such inability. Therefore it may have to liquidate other more advantageous
investments to meet its cash needs.

    In addition, FCMs or brokers in certain circumstances will have access to
each Fund's assets posted as margin in connection with these transactions as
permitted under the 1940 Act. The Funds will use only FCMs or brokers in whose
reliability and financial soundness they have confidence and have adopted
certain other procedures and limitations to reduce the risk of loss with respect
to any assets which brokers hold or to which they may have access. Nevertheless,
in the event of a broker's insolvency or bankruptcy, it is possible that a Fund
could experience a delay or incur costs in recovering such assets or might
recover less than the full amount due. Also, the value of such assets could
decline by the

                                       21
<PAGE>

time the Fund could effect such recovery.

    The success of any Fund in using hedging techniques depends, among other
things, on the Adviser's ability to predict the direction and volatility of
price movements in both the futures and options markets as well as the
securities markets and on its ability to select the proper type, time and
duration of hedges. There can be no assurance that the Adviser will employ these
techniques or that, if employed, these techniques will produce their intended
results. In any event, the Adviser will use financial futures contracts, options
thereon and stock index options only when it believes the overall effect is to
reduce, rather than increase, the risks to which a Fund is exposed. Hedging
transactions also, of course, may be more, rather than less, favorable to a Fund
than originally anticipated.

RESTRICTED SECURITIES AND OTHER ILLIQUID INVESTMENTS

     The Adviser is responsible for determining the value and liquidity of
investments held by each Fund. Investments may be illiquid because of the
absence of a trading market, making it difficult to value them or dispose of
them promptly at an acceptable price. Each of the Money Market Fund, the
Government Securities Fund and the S&P 500 Index Fund will not purchase or
otherwise acquire any investment if, as a result, more than 10% of its net
assets (taken at current value) would be invested in instruments that are
illiquid by virtue of the absence of a readily available market. Each of the
Asset Allocation Fund, the International Equity Fund and the REIT Index Fund
will not purchase or otherwise acquire any investment if, as a result, more than
15% of its net assets (taken at current value) would be invested in instruments
that are illiquid by virtue of the absence of a readily available market.

     Illiquid investments include most repurchase agreements maturing in more
than seven days, currency swaps, time deposits with a notice or demand period of
more than seven days, certain over-the-counter option contracts (and segregated
assets used to cover such options), participation interests in loans, and
restricted securities. A restricted security is one that has a contractual
restriction on resale or cannot be resold publicly until it is registered under
the Securities Act of 1933.

     The foregoing illiquid investment restrictions do not apply to purchases of
restricted securities eligible for sale to qualified institutional purchasers in
reliance upon Rule 144A under the Securities Act of 1933 that are determined to
be liquid by the Trust's Board of Trustees or by the Adviser under the general
oversight of the Trustees. Such determination would take into account trading
activity for such securities and the availability of reliable pricing
information, among other factors. To the extent that qualified institutional
buyers become for a time uninterested in purchasing these restricted securities,
a Fund's holdings of those securities may become illiquid. The foregoing
investment restrictions also do not apply to purchases of securities of foreign
issuers offered and sold outside the United States in reliance upon the
exemption from registration provided by Regulation S under the Securities Act of
1933.

BORROWING

    From time to time, the International Equity Fund may increase its ownership
of investments by borrowing from banks on an unsecured basis and investing the
borrowed funds (on which the Fund pays interest). The Fund may borrow only up to
10% of the value of its total assets for this purpose and may not borrow unless
the value of its assets, less its liabilities other than borrowing, is equal to
at least 300% of all borrowings, including any additional proposed borrowings.
If the value of the Fund's assets so computed should fail to meet the 300% asset
coverage requirement, the Fund must, within three days, reduce its borrowing to
the extent necessary to meet the coverage requirement and may have to sell a
portion of its investments at an inopportune time. Borrowing for investment, or
"leverage," increases investment opportunity but also risk and costs (which may
include commitment fees and/or the cost of maintaining minimum average balances
with the lender). Interest on borrowed money is an expense that the Fund would
not otherwise incur, so that it may have little or no net investment income
during periods of borrowing. Since substantially all of the Fund's assets
fluctuate in value whereas borrowing obligations are fixed, when the Fund has
outstanding borrowings, its net asset value tends to increase and decrease more
when portfolio investments increase and decrease, respectively, than would
otherwise be the case.

LOWER-RATED, LOWER QUALITY DEBT INSTRUMENTS

                                       22
<PAGE>

    Up to 30% of the total assets of the Asset Allocation Fund may be invested
in debt instruments that are unrated or are rated lower than the four highest
rating categories assigned by Moody's or S&P. Furthermore, debt instruments that
are rated in the four highest categories assigned by Moody's or S&P (i.e.,
investment grade debt instruments), and especially those which are investment
grade but are not high quality (i.e., rated Baa by Moody's or BBB by S&P) may,
after purchase by the Fund, have their ratings lowered due to the deterioration
of the issuer's financial position.

RISKS OF LOWER-RATED, LOWER QUALITY DEBT INSTRUMENTS

    Lower-rated fixed income securities (i.e., those rated Ba or lower by
Moody's or BB or lower by S&P) are considered, on balance, as predominantly
speculative with respect to capacity to pay interest and repay principal in
accordance with the terms of the obligation and will generally involve more
credit risk than securities in the higher rated categories. Reliance on credit
ratings entails greater risks with regard to lower-rated securities than it does
with regard to higher-rated securities and the Adviser's success is more
dependent upon its own credit analysis with regard to lower-rated securities
than is the case with regard to higher-rated securities. The market values of
such securities tend to reflect individual corporate developments to a greater
extent than do higher-rated securities, which react primarily to fluctuations in
the general level of interest rates. Such lower-rated securities also tend to be
more sensitive to economic conditions than are higher-rated securities. Adverse
publicity and investor perceptions, whether or not based on fundamental
analysis, regarding lower-rated bonds may depress prices and liquidity for such
securities. To the extent the Asset Allocation Fund invests in these securities,
factors adversely affecting the market value of high-yielding securities will
adversely affect the Fund's net asset value. In addition, the Asset Allocation
Fund may incur additional expenses to the extent it is required to seek recovery
upon a default in the payment of principal or interest on its portfolio
holdings. Although some risk is inherent in all securities ownership, holders of
fixed-income securities have a claim on the assets of the issuer prior to the
holders of common stock. Therefore, an investment in fixed-income securities
generally entails less risk than an investment in common stock of the same
issuer.

    High yielding securities may be issued by corporations in the growth stage
of their development. They may also be issued in connection with corporate
reorganization or as a part of a corporate takeover. Companies that issue such
high-yielding securities are often highly leveraged and may not have available
to them more traditional methods of financing. Therefore, the risk associated
with acquiring the securities of such issuers generally is greater than is the
case with higher rated securities. For example, during an economic downturn or a
sustained period of rising interest rates, highly leveraged issuers of
high-yielding securities may experience financial stress. During such periods,
such issuers may not have sufficient revenues to meet their interest payment
obligations. The issuer's ability to service its debt obligations may also be
adversely affected by specific corporate developments or the issuers inability
to meet specific projected business forecasts, or the unavailability of
additional financing. The risk of loss due to default by the issuer is
significantly greater for the holders of high-yielding securities because such
securities are generally unsecured and are often subordinated to other creditors
of the issuer.

    High yielding securities frequently have call or buy-back features that
would permit an issuer to call or repurchase the security from the Fund. If a
call were exercised by the issuer during a period of declining interest rates,
the Fund would likely have to replace such called security with a lower yielding
security, thus decreasing the net investment income to the Fund.

    The Asset Allocation Fund may have difficulty disposing of certain
high-yielding securities for which there is a thin trading market. Because not
all dealers maintain markets in all high-yielding securities, there is no
established retail secondary market for many of these securities, and the Trust
anticipates that they could be sold only to a limited number of dealers or
institutional investors. To the extent there is a secondary trading market for
high-yielding securities, it is generally not as liquid as that for higher-rated
securities. The lack of a liquid secondary market for certain securities may
make it more difficult for the Trust to obtain accurate market quotations for
purposes of valuing the Fund's assets. Market quotations are generally available
on many high-yield issues only from a limited number of dealers and may not
necessarily represent firm bids of such dealers or prices for actual sales. When
market quotations are not readily available, lower-rated securities must be
valued by (or under the direction of) the Board of Trustees of the Trust. This
valuation is more difficult and judgment plays a greater role in such valuation
when there is less reliable objective data

                                       23
<PAGE>

available.

    The Asset Allocation Fund may acquire high-yielding securities that are sold
without registration under the federal securities laws and therefore carry
restrictions on resale. This Fund may incur special costs in disposing of such
securities, but will generally incur no costs when the issuer is responsible for
registering the securities. The Fund also may acquire high-yielding securities
during an initial underwriting. Such securities involve special risks because
they are new issues. The Trust has no arrangement with any person concerning the
acquisition of such securities, and the Adviser will carefully review the credit
and other characteristics pertinent to such new issues.

    From time to time, there have been proposals for legislation designed to
limit the use of certain high-yielding securities in connection with leveraged
buy-outs, mergers and acquisitions, or to limit the deductibility of interest
payments on such securities. Such proposals if enacted into law could reduce the
market for such securities generally, could negatively affect the financial
condition of issuers of high-yield securities by removing or reducing a source
of future financing, and could negatively affect the value of specific
high-yield issues. However, the likelihood of any such legislation or the effect
thereof is uncertain.

COVERED CALL OPTIONS

    The Asset Allocation Fund may write covered call options that are traded on
a national securities exchange with respect to securities in the Fund (ensuring
that at all times the Fund will have the securities which it may be obligated to
deliver if the option is exercised). The Fund may write call options on its
securities in an attempt to realize a greater current return than would be
realized on the securities alone or to provide greater flexibility in disposing
of such securities. As the writer of a call option, the Fund receives a premium
for undertaking the obligation to sell the underlying security at a fixed price
during the option period if the option is exercised. So long as the Fund remains
obligated as a writer of a call, it forgoes the opportunity to profit from
increases in the market price of the underlying security above the call price of
the option, except insofar as the premium represents such a profit.

    The Asset Allocation Fund may also enter into "closing purchase
transactions" in order to terminate its obligation as a writer of a call option
prior to the expiration of the option. Although writing only those call options
that are traded on a national securities exchange increases the likelihood of
being able to make closing purchase transactions, there is no assurance that the
Fund will be able to effect such transactions at any particular time or at any
acceptable price. The writing of call options could result in increases in the
turnover rate of the Fund, especially during periods when market prices of the
underlying securities appreciate, which could affect brokerage costs.

GNMA CERTIFICATES

    The Asset Allocation and Government Securities Funds may each invest up to
50% of its net assets in GNMA Certificates. GNMA Certificates are securities
representing part ownership of a pool of mortgage loans. These loans, issued by
lenders such as mortgage bankers, commercial banks and savings and loan
associations, are insured either by the Federal Housing Administration or by the
Veterans Administration. Each pool of mortgage loans is assembled and, after
being approved by GNMA, is sold to investors through broker-dealers in a form of
certificates representing participation in the pool. GNMA guarantees the timely
payment of principal and interest of each mortgage in the pool and its guarantee
is backed by the full faith and credit of the U.S. Government. GNMA Certificates
differ from bonds in that a borrower pays the principal over the term of the
loan rather than in a lump sum at maturity. GNMA Certificates are called
"pass-through" certificates because both principal and interest payments on the
mortgages (including prepayments) are passed through to the holder of the
certificate.

    The average life of GNMA Certificates varies with the maturities of the
underlying mortgages. The Asset Allocation and the Government Securities Funds
may each use principal payments it receives to purchase additional GNMA
Certificates or other permitted investments. Prepayments of any mortgages in the
pool will usually result in the return of the greatest part of principal
invested well before the maturity of the mortgages in the pool. The volume of
such prepayments of principal in a given pool of mortgages will influence the
actual yield of the GNMA Certificate. Also, the Asset Allocation and the
Government Securities Funds may each reinvest principal repaid to it in
instruments whose

                                       24
<PAGE>

yield may be higher or lower than that of the GNMA Certificate had such
prepayments not been made.


OTHER INVESTMENT PRACTICES

The S&P 500 Index Fund may choose not to invest in all the stocks that comprise
the S&P 500 Index, and its holdings may be invested differently by industry
segment than the S&P 500 Index. The Fund may compensate for the omission by
investing in stocks with characteristics similar to omitted stocks (such as
stocks from the same or similar industry groups having similar market
capitalizations and other investment characteristics).

     Although the REIT Index Fund may at times hold each stock in the Morgan
Stanley REIT Index in roughly the same proportions as in the Index itself, it
may choose not to invest in all the stocks that comprise the Morgan Stanley REIT
Index. The Fund may compensate by investing in stocks with characteristics
similar to omitted stocks (such as stocks representing the same or similar
property types or regions or having similar market capitalizations and other
investment characteristics).


INVESTMENT RESTRICTIONS

    FUNDAMENTAL INVESTMENT RESTRICTIONS. Each Non-Money Market Fund has adopted
a number of fundamental policies restricting the investment of its assets, which
may not be changed without the affirmative vote of the holders of a majority of
such Fund's outstanding voting securities. The "affirmative vote of the holders
of a majority of such Fund's outstanding securities" has the meaning set forth
under "General Information" above. Pursuant to the fundamental investment
restrictions of each Non-Money Market Fund other than the Asset Allocation Fund,
except where otherwise noted, each such Fund may not:

        (1) issue senior securities except: (a) to the extent that borrowing
    under paragraph (8) below exceeding 5% may be deemed to be senior securities
    under the 1940 Act, or (b) in connection with investments of certain Funds
    in options, futures and swap contracts;

        (2) as to 75% of its total assets, invest more than 5% of its total
    assets in the securities of any one issuer (other than U.S. Government
    securities, as defined in Section 2(a)(16) of the 1940 Act) or invest in
    more than 10% of the outstanding voting securities of any one issuer;

        (3) invest more than 25% of its total assets in the securities of
    issuers primarily engaged in the same industry, other than U.S. Government
    securities; utilities will be divided according to their services; for
    example, gas, gas transmission, electric and telephone each will be
    considered a separate industry for purposes of this restriction. This
    restriction does not apply to the REIT Index Fund;

        (4) purchase real estate or any interest therein, except through the
    purchase of corporate or certain government securities (including securities
    secured by a mortgage or a leasehold interest or other interest in real
    estate). A security issued by a real estate or mortgage investment trust is
    not treated as an interest in real estate;

        (5) purchase any securities on margin except: (a) that a Fund may obtain
    such short-term credit as may be necessary for the clearance of purchases
    and sales of portfolio securities, and (b) in connection with investments in
    options, futures and swap contracts;

        (6) make loans, except as provided in (7) below and except through the
    purchase of obligations in private placements (the purchase of
    publicly-traded obligations not being considered the making of a loan);

        (7) lend its portfolio securities in excess of 20% of its total assets,
    taken at market value at the time of the loan;

        (8) borrow amounts in excess of 10% (20% in the case of the S&P 500
    Index Fund and the REIT Index Fund) of its total assets, taken at market
    value at the time of the borrowing, and then only from banks as a temporary
    measure

                                       25
<PAGE>

    for extraordinary or emergency purposes or to meet redemption requests that
    might otherwise require the untimely disposition of securities, and not for
    investment or leveraging. The International Equity Fund, however, may borrow
    amounts up to an additional 10% of its net asset value from banks to
    increase its holdings of portfolio investments;

        (9) mortgage, pledge, hypothecate or in any manner transfer, as security
    for indebtedness, any securities owned or held by such Fund except: (a) as
    may be necessary in connection with borrowing mentioned in (8) above, and
    then such mortgaging, pledging or hypothecating may not exceed 10% of the
    Fund's total assets, taken at market value at the time thereof, or (b) in
    connection with investment of certain Funds in options, futures and swap
    contracts;

        (10) underwrite securities of other issuers except insofar as the Trust
    may be deemed an underwriter under the Securities Act of 1933 in selling
    portfolio securities;

        (11) invest more than 10% of its net assets (15% for the International
    Equity Fund and REIT Index Fund) in repurchase agreements maturing in more
    than seven days and other illiquid investments; and

        (12) purchase or sell interests in oil, gas or other mineral exploration
    or development programs, commodities, or commodity contracts, except that
    such Funds may invest in financial futures contracts and related options;

    Pursuant to the fundamental investment restrictions of the Asset Allocation
Fund, such Fund may not:

        (1) issue senior securities (except to the extent that borrowings under
    paragraph (8) below exceeding 5% of the value of the Fund's total assets may
    be deemed to constitute senior securities under the 1940 Act); however, this
    prohibition shall not limit the Fund's ability to write covered call
    options;

        (2) purchase real estate or any interest therein, except through the
    purchase of corporate or certain government securities (including securities
    secured by a mortgage or a leasehold interest or other interest in real
    estate). A security issued by a real estate or mortgage investment trust is
    not treated as an interest in real estate;

        (3) purchase any securities on margin (except that, subject to the
    borrowing limitation in (8), the Fund may obtain such short-term credit as
    may be necessary for the clearance of purchases and sales of portfolio
    securities), or make short sales of securities or maintain a short position.
    However, this prohibition shall not limit the Fund's ability to write
    covered call options;

        (4) underwrite securities of other issuers (except insofar as the Fund
    or the Trust might be deemed an underwriter under the Securities Act of 1933
    in certain resales of portfolio securities held by the Fund);

        (5) invest more than 25% of the value of its total assets in the
    securities of issuers having their principal activity in any particular
    industry, other than U.S. Government securities, as defined in Section 2(a)
    (16) of the 1940 Act. For the purpose of defining the term "particular
    industry," utilities will be divided according to their services. For
    example, gas, gas transmission, electric and telephone each will be
    considered a separate industry;

        (6) as to 75% of its total assets, invest more than 5% of its total
    assets in the securities of any one issuer (except that this restriction
    shall not apply to U.S. Government securities) or invest in more than 10% of
    the outstanding voting securities of any one issuer;

        (7) make loans, except that the Fund may enter into repurchase
    agreements as described above or in the Prospectus, and the Fund may lend
    its portfolio securities in amounts up to 20% of the value of its total
    assets;

        (8) borrow money, except from banks for temporary or emergency purposes,
    including the meeting of redemption requests which might otherwise require
    the untimely disposition of securities. Borrowing in the aggregate may not
    exceed 10% of the value of the Fund's total assets at the time the borrowing
    is made, and the Fund will not make additional investments during any period
    that borrowings exceed 5% of the value of its total assets. This limitation
    on borrowing money shall not limit the Fund's ability to write covered call
    options;

                                       26
<PAGE>

        (9) pledge, hypothecate, mortgage or transfer as security for
    indebtedness any securities held by the Fund, except in an amount of not
    more than 10% of the value of its total net assets, and then only to secure
    borrowings permitted by (3) and (8);

        (10) invest in illiquid securities, including repurchase agreements
    maturing in more than seven days, if, as a result thereof, more than 15% of
    the value of the Fund's total assets would be invested in such illiquid
    securities;

        (11) invest in time deposits maturing in more than seven days. In
    addition, time deposits maturing in two business days to seven calendar days
    may not exceed 10% of the value of the Fund's total assets; and

        (12) purchase or sell interests in oil, gas, or other mineral
    exploration or development programs, commodities, or commodity contracts,
    except that the Fund may purchase securities of issuers which invest or deal
    in any of the above, provided that such securities meet the Fund's other
    investment criteria.

    With respect to fundamental investment restriction (10) of the Asset
Allocation Fund set forth above, the Trust has been advised by the SEC that,
under the SEC's guidelines, the Asset Allocation Fund may not invest more than
15% of the value of such Fund's net assets in illiquid securities. Accordingly,
in order to comply with the SEC's guidelines, as a matter of non-fundamental
policy such Fund will not invest in illiquid securities, including repurchase
agreements maturing in more than seven days, if, as a result thereof, more than
15% of the value of such Fund's net assets would be invested in such illiquid
securities. The Trust has undertaken to the SEC that it will comply with this
non-fundamental policy until such time as the shareholders of the Asset
Allocation Fund approve an amendment to the fundamental policies of such Fund
incorporating into such fundamental policies this non-fundamental policy.

    NON-FUNDAMENTAL RESTRICTIONS. In addition to the fundamental investment
restrictions set forth above, each Non-Money Market Fund is subject to the
following additional restrictions in implementing its investment policy. These
additional restrictions are not fundamental and may be changed by the Trustees
without shareholder approval. These Funds are subject to the same
non-fundamental investment restrictions as apply to the Money Market Fund
(described above) except as modified below.

        (1) each Non-Money Market Fund will not purchase securities of other
    investment companies if, as a result thereof, the Fund would own more than
    3% of the total outstanding voting stock of any one investment company, or
    more than 5% of the Fund's assets would be invested in any one investment
    company, or more than 10% of the Fund's total assets would be invested in
    securities of investment companies. These limitations do not apply to
    securities acquired in connection with a merger, consolidation, acquisition
    or reorganization, or by purchase in the open market of securities of
    closed-end investment companies where no underwriter or dealer's commission
    or profit, other than customary broker's commission, is involved, and so
    long as immediately thereafter not more than 10% of such Fund's total
    assets, taken at market value, would be invested in such securities;

        (2) each Non-Money Market Fund will not invest more than 30% of its
    total assets, measured at the time of investment, in debt securities (other
    than U.S. Government securities) that are rated lower than the four highest
    rating categories by Moody's or S&P or are unrated. This restriction shall
    apply to such unrated securities as the Adviser may determine, pursuant to
    procedures adopted by the Trustees to be of comparable quality to those
    securities assigned a rating in one of the four highest categories;

        (3) each Non-Money Market Fund (other than the S&P 500 Index Fund and
    the REIT Index Fund) will not purchase or retain the securities of any
    issuer if any officer or Trustee of the Trust, the Adviser or any affiliated
    person of the Trust or the Adviser beneficially own more than 0.5% of the
    securities of such issuer or together in the aggregate own more than 5% of
    the securities of such issuer;

        (4) the S&P 500 Index Fund, Government Securities Fund, International
    Equity Fund and REIT Index Fund will not enter into a speculative financial
    futures contract (by exercise of any option or otherwise) or acquire any
    options thereon, if, immediately thereafter, the total of the initial margin
    deposits required with respect to all open

                                       27
<PAGE>

    speculative futures positions, plus the sum of the premiums paid for all
    unexpired options on futures contracts (less any in-the-money amount at the
    time of purchase) would exceed 5% of the market value of its total assets
    (after taking into account unrealized profits and losses on any such futures
    contracts or options it has entered into);

        (5) Non-fundamental investment restriction (a) of the Money Market Fund
    is not applicable to the Government Securities, S&P 500 Index, REIT Index or
    International Equity Fund; and

        (6) Non-fundamental investment restriction (b) of the Money Market Fund
    is not applicable to the International Equity Fund.

INVESTMENT ADVISER

     Aon Advisors, Inc., 123 North Wacker Drive, Chicago, Illinois, a wholly
owned subsidiary of Aon Corporation, serves as an investment adviser to the
Trust pursuant to separate investment advisory agreements relating to each Fund
("Advisory Agreements") each dated September 3, 1996. Information concerning AAI
and the basic provisions of the Advisory Agreements are described in the
Prospectus under the caption "Management of the Trust--Investment Adviser."

    The duties and responsibilities of AAI are specified in the Advisory
Agreements. Each of the Advisory Agreements

                                       29
<PAGE>

was approved by the Trustees of the Trust (including a majority of Trustees who
are not parties to the Advisory Agreement or interested persons, as defined by
the 1940 Act, of any such party) at a meeting held on May 22, 1996, and the
continuation of the Advisory Agreements was last approved by such Trustees at a
meeting held July 29, 1998. The Advisory Agreements were also approved by the
respective shareholders of the Money Market Fund and the Asset Allocation Fund
on July 10, 1996 and by the respective initial shareholders of each of the other
Funds on September 3, 1996. The Advisory Agreements are not assignable and may
be terminated without penalty upon 60 days written notice at the option of
either the Trust or AAI or by a vote of shareholders of each respective Fund.
Each Advisory Agreement provides that it shall continue in effect for two years
and can thereafter be continued from year to year so long as such continuation
is specifically approved annually (a) by the Trustees of the Trust or by a
majority of the outstanding shares of the Fund and (b) by a majority vote of the
Trustees who are not parties to the Advisory Agreements or interested persons of
any such party to cast in person at a meeting.

    AAI (under the general oversight of the Trustees) continuously furnishes an
investment program for each Fund, is responsible for the actual managing of the
investments of each Fund and has responsibility for making decisions governing
whether to buy, sell or hold any particular security. In carrying out its
obligations to manage the investment and reinvestment of the assets of each
Fund, AAI performs research and obtains and evaluates pertinent economic,
statistical and financial data relevant to the investment policies of each Fund.

    The Advisory Agreements provide that AAI shall not be liable to the Trust or
to any shareholder for any error of judgment or mistake of law or for any loss
suffered by the Trust or by any shareholder in connection with matters to which
the Advisory Agreements relate, except for a breach of fiduciary duty or a loss
resulting from willful misfeasance, bad faith, gross negligence, or reckless
disregard on the part of AAI in the performance of its duties thereunder.


    As described below, AAI has engaged Brinson Partners as the investment
sub-adviser to provide day-to-day portfolio management for the International
Equity Fund.

    Pursuant to a separate administration agreement between the Trust and Aon
Securities Corporation ("ASC"), a wholly owned subsidiary of Aon (the
"Administration Agreement"), ASC has agreed, at its own expense, to:

         stationery and office supplies; (3) prepare reports to shareholders and
         the Board of Trustees; (4) prepare tax returns; (5) prepare reports to

         upon from time to time, and all necessary office facilities; (7) supply
         clerical, accounting, bookkeeping, administrative and other similar
         services (exclusive of those services relating to and to be performed
         under any contract for custodial, transfer, dividend and accounting
         services entered into by the Trust with a third party); and (8) furnish
         persons satisfactory to the Trust to respond during normal business
         hours to in-person, written and telephone requests for assistance and
         information from shareholders of the Trust, and provide such facilities
         and equipment as may be necessary for such persons to carry out their
         duties, including, without limitation, office space and facilities,
         telephones and CRT terminals and equipment (including telephone lines)
         necessary for access to the Trust shareholder records.

    The Trust is responsible for all other expenses, including:

         (1) taxes and fees payable by the Trust to federal, state, or other
         government agencies; (2) brokerage fees and commissions, and issue and
         transfer taxes; (3) interest; (4) Board of Trustees meeting attendance
         and annual retainer fees and expenses of trustees of the Trust who are
         not directors, officers or employees of AAI, or of any affiliated
         person (other than a registered investment company) of AAI; (5)
         registration, qualification, filing and other fees in connection with
         securities registration requirements of federal and state regulatory
         authorities; (6) the charges and expenses for custodial, paying agent,

INVESTMENT SUB-ADVISER

    Pursuant to a separate sub-advisory agreement described below, AAI has
engaged Brinson Partners, Inc. as the investment subadviser to provide
day-to-day portfolio management for the International Equity Fund. Brinson
Partners is located at 209 South LaSalle Street, Chicago, Illinois 60604.
Brinson Partners is an indirect wholly owned subsidiary of UBS AG. UBS AG, with
headquarters in Zurich, Switzerland, is an internationally diversified
organization with operations in many aspects of the financial services industry.
Brinson Partners is a part of the UBS Brinson Division of UBS AG. Gary Brinson,
President and Managing Director of Brinson Partners, is the Chief Executive
Officer and Chief Investment Officer of the UBS Brinson Division. Brinson
Partners, a registered investment adviser under the Investment Advisers Act of
1940, manages approximately $173 billion of global stocks and bonds as of
December 31, 1998, and it and its predecessor entities have been managing non-US
securities since 1974.

INVESTMENT SUB-ADVISORY AGREEMENT

    AAI has entered into a separate sub-advisory agreement (the "Sub-Advisory
Agreement") with Brinson Partners for the day-to-day portfolio management of the
International Equity Fund. The Sub-Advisory Agreement was approved by a vote of
the majority of the Trustees of the Trust (including a majority of trustees who
are not parties to such Agreement or interested persons, as defined by the 1940
Act, or any such party) at a meeting held for that purpose on August 28, 1996,
and the continuation of the Sub-Advisory Agreement was last approved by such
Trustees as the meeting held July 29, 1998. The Sub-Advisory Agreement was also
approved by the initial shareholder of the International Equity Fund on
September 3, 1996. The Sub-Advisory Agreement is not assignable and may be
terminated without penalty upon 60 days' written notice at the option of AAI or
Brinson Partners, by a vote of the majority of the Trustees of the Trust or by a
vote of a majority of the outstanding shares of the International Equity Fund.
The Sub-Advisory Agreement provides that it shall continue in effect for two
years and can thereafter be continued from year to year so long as such
continuance is specifically approved annually (1) by the Trustees of the Trust
or by a majority of the outstanding shares of the International Equity Fund and
(2) by a majority vote of the Trustees who are not parties to the Agreement, or
interested persons of any such party, cast in person at a meeting held for that
purpose.

INVESTMENT SUB-ADVISORY FEES

                                       32
<PAGE>

    Brinson Partners manages the investments of the International Equity Fund,
determining which securities or other investments to buy and sell, selecting the
brokers and dealers to effect the transactions, and negotiating commissions. In
placing orders for securities transactions, Brinson Partners follows AAI's
policy of seeking to obtain the most favorable price and efficient execution
available.

    For its services, AAI pays Brinson Partners monthly compensation in the form
of an investment sub-advisory fee. The fee is paid by AAI monthly and is based
upon the average daily net assets of the Fund that Brinson Partners manages, at
the following annual rates:

    International Equity Fund: .50% of the first $100,000,000; .475% of the next
$100,000,000; and .45% of amounts in excess of $200,000,000.

REIMBURSEMENT OF EXCESS OPERATING EXPENSES

     With respect to each Fund, AAI has undertaken that if, in any fiscal year,
certain expenses of the Fund, including the investment advisory fees,
administration and accounting (but excluding interest, taxes, brokerage
commissions and extraordinary expenses), exceed the maximum total annual
operating expenses noted in the table below for such Fund, AAI shall reimburse
the Fund to the extent of such excess. AAI's undertaking with respect to
reimbursement of excess expenses cannot be changed without shareholder approval.
The maximum total annual operating expenses, as a percentage of average daily
net assets, that a Fund may incur pursuant to AAI's undertaking are as set forth
in the prospectus.

     During the fiscal year ended October 31, 1998, AAI was not required to
reimburse the Trust for expenses incurred in excess of maximum total operating
expenses.


SECURITIES ACTIVITIES OF THE ADVISER

    Securities held by the Trust may also be held by Aon Corporation, or by
accounts or mutual funds for which AAI acts as an adviser. Because of different
investment objectives or other factors, a particular security may be bought by
Aon Corporation or by AAI or for one or more of its clients, when one or more
other clients are selling the same security. If purchases or sales of securities
for a Fund or other client of AAI or Aon Corporation arise for consideration at
or about the same time, transactions in such securities will be made, insofar as
feasible, for the Trust, Aon Corporation, and other clients in a manner deemed
equitable to all. To the extent that transactions on behalf of more than one
client of AAI during the same period may increase the demand for securities
being purchased or the supply of securities being sold, there may be an adverse
effect on price.

    On occasions when AAI (under the general oversight of the Trustees of the
Trust) deems the purchase or sale of a security to be in the best interests of
the Trust as well as other accounts or companies, it may, to the extent
permitted by applicable laws and regulations, but will not be obligated to,
aggregate the securities to be sold or purchased for the Trust with those to be
sold or purchased for other accounts or companies in order to obtain favorable
execution and low brokerage commissions. In that event, allocation of the
securities purchased or sold, as well as the expenses incurred in the
transaction, will be made by AAI in the manner it considers to be most equitable
and consistent with its fiduciary obligations to the Trust and to such other
accounts or companies. In some cases this procedure may adversely affect the
size of the position obtainable for a Fund. Likewise, Brinson Partners may, to
the extent permitted by applicable laws and regulations, but will not be
obligated to, aggregate the securities to be sold or purchased for the Trust
with those to be sold or purchased for other accounts or companies in order to
obtain favorable execution and low brokerage commissions. Like AAI, Brinson
Partners allocates the securities purchased or sold, as well as the expenses
incurred in the transaction, in the manner that it considers to be most
equitable and consistent with its fiduciary obligations to the Trust and to such
other accounts or companies.

    In performing their functions, AAI and Brinson Partners will execute sales
of securities among the Funds or between a Fund and other investment accounts it
manages.

DISTRIBUTION OF SHARES

     The Trust has entered into a Distribution Agreement with Aon Securities
Corporation (the "Distributor"), 123 North Wacker Drive, Chicago, Illinois
60606, a wholly-owned subsidiary of Aon Corporation, under which the Distributor
acts as principal underwriter and distributor of the shares of each Fund. The
Trust does not pay the Distributor any fees for these services.

    Aon Corporation, a Delaware corporation, and its subsidiaries and affiliates
may, by virtue of their interests as shareholders of the Trust at any particular
time, be considered controlling persons of the Trust and may be able to cast a
deciding vote on all matters submitted to a vote of the shareholders of the
Trust or one or more of the Funds. As of December 31, 1998, Aon Corporation and
its subsidiaries and affiliates owned in excess of 98% of the outstanding shares
of the Trust. On that date, the Trustees and officers of the Trust owned less
than 1% of the outstanding shares of each of the Funds other than holdings
attributable to Michael A. Conway as co-trustee of the Aon Savings Plan and Aon
Pension Trust.

    As of February 24, 1999, Mr. Patrick G. Ryan, Chairman, President and Chief
Executive Officer of Aon, owned directly and beneficially 20,571,946 shares
(12.0%) of the outstanding common stock of Aon.


                         SHAREHOLDER MEETINGS AND VOTING

     The Trust will not hold annual shareholder meetings. Shareholders under
certain circumstances have the right to call a meeting of shareholders for the
purpose of voting to remove Board members. In addition, shareholders of the
respective Funds will have the power to vote at special meetings with respect
to, among other things, changes in fundamental investment policies and
restrictions of such Funds, approval of changes to investment advisory
agreements and such additional matters relating to the Trust or such Funds (or
classes of shares thereof) as might be required by the 1940 Act. As to any
matter on which shareholders of the Trust are entitled to vote, they shall be
entitled to one noncumulative vote for each full share and to a proportionate
fractional vote for each fractional share, irrespective of class, standing in
the shareholder's name on the books of the Trust. In no event shall holders of
shares of a series or

                                       35
<PAGE>

class be entitled to vote such shares with respect to any matter that does not
affect any interest of such series or class, as the case may be, unless
otherwise required by the 1940 Act. All shares then issued and outstanding and
entitled to be voted shall be voted on a series by series basis, except that (1)
shares shall be voted in the aggregate without differentiation among the
separate series and classes in the case of the election or removal of Trustees
and where otherwise required by the 1940 Act or the Trust's Agreement and
Declaration of Trust, (2) shares shall be voted by class where required by the
1940 Act, and (3) the Trustees in their sole discretion may determine that, in
situations where the shares of more than one series or class are entitled to be
voted with respect to a matter, such shares shall be voted as a single class
with respect to such matter if and to the extent permitted under the 1940 Act.
Shares do not have preemptive or subscription rights.


                      PORTFOLIO TRANSACTIONS AND BROKERAGE

    The Adviser determines which securities to buy and sell for each Fund,
selects brokers and dealers to effect the transactions, and negotiates
commissions. Transactions in equity securities will usually be executed through
brokers who will receive a commission paid by such Fund. Fixed income securities
are generally traded with dealers acting as principal for their own accounts
without a stated commission. The dealer's margin is reflected in the price of
the security. Money market instruments may be traded directly with the issuer.
Underwritten offerings of stock or fixed-income securities may be purchased at a
price that includes compensation to the underwriter.

    Decisions with respect to the purchase and sale of the Fund's portfolio,
including allocation of portfolio business and the negotiation of the price of
the securities and commissions, if any, are made by the Adviser. Neither the
Adviser nor any company affiliated with it will act as a broker or dealer for
the purposes of executing portfolio transactions for the Funds.

    The primary consideration in allocating transactions to brokers or dealers
is prompt and effective execution of orders at the most favorable security
prices obtainable ("best execution"). When this primary consideration of best
execution has been met, consideration may be given to additional factors, such
as furnishing of supplemental research and other services deemed to be of value
to the Trust or to the Adviser; the Adviser is authorized to execute orders with
dealers or brokers that provide research and security and economic analysis that
supplements the research and analysis of the Adviser, even through the spread or
commission at which an order is executed may be higher than that which another
dealer or broker might charge, provided the Adviser determines in good faith
that the amount of the spread or commission is reasonable in relation to the
value of the services provided. Such research and services include advice as to
the value of securities, and advisability of securities or purchasers or sellers
of securities; furnishing analyses and reports concerning issuers, industries,
securities, economic factors and trends, portfolio strategy and performance of
accounts; and effecting securities transactions and performing functions
incidental thereto (such as clearance and settlement). The research may be
useful to the Adviser in serving all the Funds and other accounts managed by the
Adviser and, conversely, supplemental research obtained by the placement of
business of such other accounts may be useful to the Adviser in carrying out its
obligations to the Funds.

The Funds paid the following amounts in brokerage commissions during the last
three fiscal years:

    Arrangements exist with broker-dealers whereby the adviser obtains
computerized stock quotation services and other research services in exchange
for the direction of portfolio transactions which have generated certain amounts
of dealer concessions or brokerage commissions for such broker-dealer. From time
to time, the adviser may make other similar arrangements with brokers or dealers
who agree to provide research services in consideration for certain amounts of
dealer concessions or brokerage commissions. Brokerage will be directed to such
brokers or dealers pursuant to any such arrangement only when the adviser
believes that the commissions charged are reasonable in relation to the value
and overall quality of the brokerage and research services provided.

For the year ended October 31, 1998, the amount of transactions and related
brokerage commissions allocated to brokers because of research services provided
to the Funds were as follows:

                        DETERMINATION OF NET ASSET VALUE

GENERAL

    The Trust is open for business on each day that the New York Stock Exchange
is open for trading (the NYSE is closed on: New Year's Day, Martin Luther King,
Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day and Christmas Day), except that shares of the Money Market
Fund and Government Securities Fund may not be purchased or redeemed on Columbus
Day or Veterans' Day.

    The net asset value of the Money Market Fund's shares for purposes of
pricing orders for purchase and redemption of shares is determined twice daily,
once as of 12:30 p.m. (Central Time) and again as of the close of regular
trading (currently 3:00 p.m. Central Time) on the NYSE, on each day the Trust is
open for business. The net asset value of the Non-Money Market Funds' shares for
the purposes of pricing orders for purchase and redemption of shares is
determined as of the close of regular trading (currently 3:00 p.m. Central Time)
on the NYSE, on each day that the Trust is open for business.

    The net asset value per share of each Fund is determined by subtracting the
liabilities of such Fund from the value of its assets and dividing the remainder
by the number of outstanding shares of such Fund.

MONEY MARKET FUND

    The Trust intends to use its best efforts to maintain the Money Market
Fund's net asset value at $1.00 per share, although there is no assurance that
it will be able to do so on a continuous basis. Net asset value is computed
using the amortized cost method. The Trustees of the Trust will take such action
as they deem appropriate to eliminate or reduce, to the extent reasonably
practicable, any material dilution or other unfair results that might arise from
differences between net asset value per share based on market value and net
asset value per share based on amortized cost. Such action may include
redemption in kind, selling portfolio instruments prior to maturity to realize
capital gains or losses or to shorten the average portfolio maturity,
withholding dividends or utilizing a net asset value per share as determined by
using available market quotations, if available, or, if not available, at a fair
value as determined in good faith by the Trustees. The Trust may also reduce the
number of the Money Market Fund's outstanding shares by redeeming
proportionately from shareholders, without the payment of any monetary
consideration, such number in full and fractional shares as is necessary to
maintain the net asset value per share at $1.00. By investment in the Money
Market

                                       38
<PAGE>

Fund, shareholders are deemed to have agreed to such redemption.

NON-MONEY MARKET FUNDS

    Equity securities (including common stocks, preferred stocks, convertible
securities and warrants) and call options written on all portfolio securities,
listed or traded on a national exchange are valued at their last sale price on
the exchange prior to the time when assets are valued. In the absence of any
exchange sales on that day and for unlisted equity securities, such securities
are valued at the last sale price on the Nasdaq Stock Market's National Market.
In the absence of any Nasdaq National Market sales on that day, equity
securities are valued at the last reported bid price.

    Debt securities are valued by an independent pricing service that utilizes
electronic data processing techniques, including a "matrix system," to derive
evaluated bid prices.

    Securities that are primarily traded on foreign securities exchanges are
generally valued at the last sale price on the exchange where they are primarily
traded. All foreign securities traded on the over-the-counter market are valued
at the last sale quotation, if market quotations are available, or the last
reported bid price if there is no active trading in a particular security on a
given day. Quotations of foreign securities in foreign currencies are converted,
at current exchange rates, to their U.S. dollar equivalents in order to
determine their current value. In addition, because of the need to value foreign
securities (other than ADRs) as of the close of trading on various exchanges and
over-the-counter markets throughout the world, the calculation of the net asset
value of Funds investing in foreign securities may not take place
contemporaneously with the valuation of such foreign securities in such Fund.

    Securities for which market quotations are not readily available are valued
at fair value as determined in good faith by or under the direction of the
Trustees of the Trust, including valuations provided by a pricing service
retained for this purpose.

    Exchange listed put options written and options purchased are valued on the
primary exchange on which they are traded. Over-the-counter options written or
purchased by a Fund are valued based upon prices provided by market-makers in
such securities. Exchange-traded financial futures contracts are valued at their
settlement price established each day by the board of trade or exchange on which
they are traded.

    Short-term debt securities are generally valued on an amortized cost basis.
Under the amortized cost basis method of valuation, the security is initially
valued at its purchase price and thereafter by amortizing any premium or
discount uniformly to maturity. If for any reason the Trustees of the Trust
believe the amortized cost method of valuation does not fairly reflect the fair
value of any security, fair value will be determined in good faith by or under
the direction of the Trustees of the Trust.


                               RETIREMENT PROGRAMS

    The Trust makes available a Retirement Plan for Self-Employed Individuals
("Keogh Plan") with both money purchase pension plan and profit sharing plan
options, Simplified Employee Pension Plans ("SEPs") and Individual Retirement
Accounts ("IRAs"). Contributions to each are invested, and dividends and
distributions are automatically reinvested, in shares of the appropriate Fund.
Generally, the maximum contribution allowable each year to an IRA is the lesser
of $2,000 or 100% of compensation includible in gross income for the year, and
the maximum annual contribution allowable to a Keogh Plan is the lesser of (i)
$30,000 or (ii) 25% of an employee's compensation or a self-employed
individuals' earned income (net earnings reduced by Keogh Plan contributions)
for the year. Additionally, the maximum deduction allowable each year for
contributions to the profit sharing option of a Keogh Plan is, generally, 15% of
an employee's compensation or a self-employed individual's earned income (net
earnings reduced by Keogh Plan contributions) for the year. Under a SEP, an
employer, or self-employed individual, is permitted to contribute a
discretionary amount each year up to the lesser of $30,000 or 15% of an
employee's compensation for the year, or a self-employed individual's earned
income (net earnings reduced by SEP contributions) for the year, into an
individual IRA for each employee or self-employed individual. The annual
compensation of each employee and the earned income of

                                       39
<PAGE>

each self-employed individual which can be taken into account under a Keogh Plan
and a SEP for any year cannot exceed $150,000 ($160,000 for 1997) as increased
by the cost-of-living adjustments for the calendar year after 1994 as determined
by the Internal Revenue Service. A self-employed individual may contribute to
either a Keogh Plan or a SEP and, in either case, may also contribute to an IRA.
The custodial agreements for the IRAs provide that Firstar Mutual Fund Services
LLC, Milwaukee, Wisconsin, will provide the custodial service unless a different
custodian is specified.

    Firstar Mutual Fund Services LLC would receive as compensation from the
participant under the Keogh Plan an annual maintenance fee of $12.50 per
participant. Special services not contemplated in the annual maintenance fee
will be rendered by Firstar Mutual Fund Services LLC for such additional charges
as will reasonably compensate it for the services provided. Fees may be changed
with at least 30 days' prior written notice. The annual maintenance fee payable
to Firstar Mutual Fund Services LLC with respect to an IRA, including each
individual IRA established under a SEP, is presently $12.50 per account and may
be changed at any time. Fees under any of these types of accounts remaining
unpaid may be charged against the accounts. If a custodian other than Firstar
Mutual Fund Services LLC is specified, fees will be determined by such
custodian.

     The Trust intends to request the Internal Revenue Service (the "IRS") to
issue an opinion letter that its Keogh Plan is qualified under section 401(a) of
the Internal Revenue Code of 1986, as amended (the "Code"), and it intends to
make any amendment to its Keogh Plan requested by the IRS as a condition of
issuing such opinion letter. Furthermore, the Trust intends to obtain approval
from the IRS with respect to money purchase pension plan and profit sharing plan
options for its Keogh Plan with the result that self-employed persons may adopt
either or both of such plans. The IRA Custodial Agreement has not been submitted
to the IRS for approval because it incorporates IRS form 5305-A which makes such
submission unnecessary.

    The employer or individual, as the case may be, should consult his or her
tax adviser or attorney as to the applicability of any Keogh Plan, SEP or IRA to
his or her particular situation. Additionally, since these retirement programs
involve commitments covering future years, the investment objectives of each
Fund, as described in the Prospectus and in this Statement of Additional
Information, should be carefully considered.

    For further details, including the right to appoint a successor custodian,
see the IRA Application Form, IRA Custodial Agreement and IRA Disclosure
Statement and other materials which are available from the Trust, telephone
(800) 266-3637.

qualified retirement plans or tax-sheltered annuity plans, see "Taxes" below.


                        YIELD AND PERFORMANCE INFORMATION

    The yield of the Money Market Fund for the seven-day period ended October
31, 1998 was 5.15%. This yield quotation is computed by determining the net
change (exclusive of realized gains and losses from the sale of securities and
unrealized appreciation and depreciation) in the value of a hypothetical account
having a balance of one share at the beginning of the period, subtracting a
hypothetical charge reflecting deductions from shareholder accounts, dividing
the net change in account value by the value of the account at the beginning of
the period to obtain the base period return, and analyzing this quotient on a
365-day basis (i.e., multiplying the base period return by 365/7). The net
change in account value reflects the value of additional shares purchased with
dividends from the original share and dividends declared on both the original
share and any such additional shares during this period. The effective yield of
the Money Market Fund for the seven-day period, ended October 31, 1998 was
5.28%. The effective yield is computed by adding 1 to the base period return
(calculated as described above), raising that sum to a power equal to 365
divided by 7, and subtracting 1 from the result. (The current annualized
effective yield is computed by expressing the annualized return on a compounded,
annualized basis).

    Current yields will fluctuate from time to time and are not necessarily
representative of future results. The yield is a function of the type and
quality of the instruments in the Fund, portfolio maturity and operating
expenses.

                                       40

    Current yield information may not provide a basis for comparison with bank
deposits or other investments which pay a fixed yield for a stated period of
time. From time to time, advertisements for the Money Market Fund may include
comparison of the Fund's performance to that of various market indices.

    The compound annual rates of return for the fiscal year ended October 31,
1998 and for the period from inception to October 31, 1998 for the Funds were as
follows:

                                   INCEPTION      YEAR ENDED       INCEPTION
                                      DATE         10/31/98       TO 10/31/98
                                   ---------      ----------      -----------
Government Securities Fund           9/3/96          11.72%          10.89%
Asset Allocation Fund                3/1/94            .21%          14.83%
S&P 500 Index Fund                   9/3/96          22.16%          29.03%
International Equity Fund            9/3/96           5.27%           8.78%
REIT Index Fund                      9/3/96         -13.27%           8.91%

    The preceding returns were computed in accordance with the rules for
standardized computation of performance as established by the SEC. Such rules
for standardized computation of performance provide for determining compound
annual rates of return by taking the total return of the Fund over the period in
question calculated as described in the Prospectus and "annualizing" such total
return, i.e., computing the annual rate of return which, if earned in each year
of such period, would produce the total return actually earned over such period.

    Inasmuch as the Funds have no sales load on purchases or reinvested
dividends, no deferred sales load or redemption fee, no adjustments are made for
such items in calculating performance.


MONEY MARKET FUND

     From time to time, the Money Market Fund may advertise its yield and
effective yield. Both yield figures are based on historical earnings and are not
intended to indicate future performance. It can be expected that these yields
will fluctuate substantially. The yield of the Fund refers to the income
generated by an investment in the Fund over a seven-day period (which period
will be stated in the advertisement). This income is then annualized. That is,
the amount of income generated by the investment during that week is assumed to
be generated each week over a 52-week period and is shown as a percentage of the
investment. The effective yield is calculated similarly but, when annualized,
the income earned by an investment in the Fund is assumed to be reinvested. The
effective yield will be slightly higher than the yield because of the
compounding effect of this assumed reinvestment.

GOVERNMENT SECURITIES FUND AND ASSET ALLOCATION FUND

     For purposes of advertising, performance of the Government Securities Fund
and Asset Allocation Fund may be calculated on several bases, including current
yield, average annual total return and/or total return. Current yield refers to
the Fund's annualized net investment income per share over a 30-day period,
expressed as a percentage of the net asset value per share at the end of the
period. For purposes of calculating current yield, the amount of net investment
income per share during that 30-day period, computed in accordance with
regulatory requirements, is compounded by assuming that it is reinvested at a
constant rate over a six-month period. An identical result is then assumed to
have occurred during a second six-month period which, when added to the result
for the first six months, provides an "annualized" yield for an entire one-year
period.

S&P 500 INDEX FUND, INTERNATIONAL EQUITY FUND AND REIT INDEX FUND

     For purposes of advertising, performance of the S&P 500 Index Fund, the
International Equity Fund and the REIT

                                       41
<PAGE>

Index Fund may be calculated on the basis of average annual total return and/or
total return. Average annual total return is calculated pursuant to a
standardized formula which assumes that an investment was purchased with an
initial payment of $1,000 and that the investment was redeemed at the end of a
stated period of time, after giving effect to the reinvestment of dividends and
distributions during the period. The return is expressed as a percentage rate
which, if applied on a compounded annual basis, would result in the redeemable
value of the investment at the end of the period. Advertisements of the
performance of these Funds will include the average annual total return for one,
five and ten year periods, or for shorter time periods, depending upon the
length of time during which the Fund has operated. Computations of average
annual total return for periods of less than one year represent an annualization
of actual total return for the applicable period.

     Total return is computed on a per share basis and assumes the reinvestment
of dividends and distributions. Total return generally is expressed as a
percentage rate which is calculated by combining the income and principal
changes for a specified period and dividing by the maximum offering price per
share at the beginning of the period. Advertisements may include the percentage
rate of total return or may include the value of a hypothetical investment at
the end of the period which assumes the application of the percentage rate of
total return.

     Average annual total return and total return will be calculated as
described above.



                                      TAXES

         Each Fund has qualified, and intends to remain qualified, as a
"regulated investment company" under Subchapter M of Code. In order to remain
qualified, the Fund must, among other things, (i) derive in each taxable year at
least 90% of its gross income from dividends, interest, gains from the sale or
other disposition of stock or securities or foreign currencies or other income
derived with respect to its business of investing in such stock, securities or
currencies, and (ii) diversify its holdings so that, at the end of each quarter
of its taxable year, (a) at least 50% of the value of its assets is represented
by cash, cash items, U.S. Government securities, and other securities limited,
in respect of any one issuer, to a value not greater than 5% of the value of the
Fund's total assets and 10% of the outstanding voting securities of such issuer
and (b) not more than 25% of the value of its assets is invested in the
securities of any one issuer (other than the U.S. Government).

         As a regulated investment company, a Fund is generally not subject to
U.S. federal income tax on its income and gains distributed to shareholders,
provided the Fund distributes to its shareholders at least 90% of its net
investment income (i.e., net income and gains, exclusive of net capital gains)
each year.

         If a Fund engages in certain hedged transactions, the transaction may
be treated as a deemed sale of the appreciated property which may accelerate the
gain on the hedged transaction.

         The Non-Money Market Funds, each in accordance with its investment
restrictions contained herein, may generate capital gain or loss. In addition,
if a Fund trades in certain options, futures, and forward contracts, the Fund
may be required to recognize its unrealized gains and losses on those contracts
at the end of its fiscal year. In such event, 60% of any net gain or loss will
generally be treated as long-term capital gain or loss and the remaining 40% of
such net gain or loss will be treated as short-term capital gain or loss.

         In general, distributions of net capital gain (i.e. a Fund's net
long-term capital gains in excess of its net short-term capital losses), when
designated as such by a Fund, are treated as gain recognized by you from the
sale or exchange of a capital asset held for more than one year, regardless of
how long you have held your Fund shares. In general, among other circumstances,
a Fund will generate capital gain or loss upon liquidating an investment in
order to change the composition of its investment portfolio or, due to the small
size of the Fund, in order to satisfy an unexpected level of redemption
requests.

         A non-deductible 4% excise tax will be imposed on the Fund to the
extent a Fund does not distribute during each calendar year (i) 98% of its
ordinary income for such calendar year, (ii) 98% of its capital gain net income
for the one-year period ending on October 31 of such calendar year and (iii)
certain other amounts not distributed in previous years. Each Fund intends to
distribute its income and gains in a manner so as to avoid the imposition of
this 4% excise tax.

         Distributions declared by a Fund in October, November or December of a
year, payable to you as of a record date in such a month, and paid during the
following January, will be treated for U.S. federal income tax purposes as paid
by the Fund and received by you on December 31 of the calendar year declared.

         If the net asset value of shares is reduced below your cost by a
distribution, such distribution would be taxable as described in the Prospectus,
even though the distribution might be viewed in economic terms as a return of
capital. For U.S. federal income tax purposes, your original cost continues as
your tax basis and, on redemption, your gain or loss is the difference between
such basis and the redemption price.

         Income tax withholding at a rate of 20% is applicable to any
distribution from a qualified retirement plan, such as the Defined Contribution
Plan or 403(b)(7) Plan, where the distribution is eligible for tax-free rollover
treatment but is not transferred directly to a specified retirement vehicle such
as another qualified plan or an IRA. All qualified retirement plans and plans
subject to Section 403(b) of the Internal Revenue Code must provide participants
and certain other distributees with an election to have an eligible rollover
distribution transferred directly to certain specified retirement vehicles. If a
shareholder receives a distribution which is subject to the 20% withholding
requirement and wishes to roll the distribution into another retirement vehicle
such as an IRA within 60 days without subjecting any part of the distribution to
income tax (and a possible additional 10% penalty tax if the shareholder has not
attained age 59 1/2), the shareholder will have to contribute to the IRA or
other retirement vehicle the amount of the distribution (after withholding) plus
an amount equal to the amount withheld. If the full amount of the distribution
(including the amount withheld) is not contributed to another qualified
retirement vehicle within 60 days, the portion of the distribution which is not
contributed will be subject to income tax, plus a possible additional 10%
penalty if the shareholder has not attained age 59 1/2. The amount withheld will
be applied to reduce the shareholder's federal income tax liability and may be
refunded by the Internal Revenue Service to the shareholder upon filing a
federal income tax return if the total amount withheld from the shareholder
exceeds such tax liability.

         The rules broadly define distributions which qualify for rollover
treatment. Shareholders who expect to receive distributions which may qualify
for rollover treatment and therefore may be subject to 20% withholding should
consult their own tax advisers for a complete discussion of the impact of these
rules on such distributions.


FOREIGN INVESTMENTS

         If a Fund purchases shares in a foreign corporation treated as a
"passive foreign investment company" ("PFIC") for U.S. federal income tax
purposes, the Fund may be subject to U.S. federal income tax, and an additional
charge in the nature of interest, on a portion of distributions from such
foreign corporation and on gain from the disposition of such shares
(collectively referred to as "excess distributions"), even if such excess
distributions are paid by the Fund as a dividend to its shareholders. In certain
limited circumstances, the Fund may be eligible to make a qualified electing
fund election with respect to certain PFICs in which it owns shares. Such an
election would enable the Fund to avoid the taxes on excess distributions by
including in income each year the Fund's pro rata share of the PFIC's income and
gains for that year (whether or not the Fund's share of such income and gains
are distributed to the Fund). Alternatively the Fund may be eligible to elect
under certain circumstances to treat its stock in certain PFICs as having been
sold on the last business day of each taxable year of the Fund for the stock's
fair market value, in which case the Fund would (subject to certain exceptions)
generally avoid the taxes on excess distributions. These elections, therefore,
may cause the Fund to recognize income in a particular year in excess of the
distributions it receives in that year from the PFIC.

         Each Fund investing in foreign securities, currencies or other
investments may be required to pay withholding or other taxes to foreign
governments. Foreign tax withholding from dividends and interest, if any, is
generally at a rate between 10% and 35%. The investment yield of any Fund that
invests in foreign securities, currencies or other foreign

                                       43
<PAGE>

investments will be reduced by these foreign taxes and, in general, shareholders
of such a Fund will bear the cost of any such foreign taxes.

         If, however, more than 50% of the value of a Fund's total assets as of
the close of its taxable year consists of stocks or securities of foreign
corporations, such Fund will be eligible to make an election to "pass through"
to such Fund's shareholders the amount of foreign taxes paid by such Fund. It is
not expected that any of the Funds other than the International Equity Fund will
be eligible to make such an election. However, if a Fund makes such an election,
shareholders, in general, will be required to: (1) include in gross income (in
addition to taxable dividends actually received) their pro rata share of the
foreign taxes paid by the electing Fund; (2) treat their pro rata share of such
foreign taxes as having been paid by him or her; and (3) either deduct their pro
rata share of foreign taxes in computing their taxable income or, subject to
numerous limitations, use it as a foreign tax credit against U.S. income taxes.
The foregoing is only a general description of the foreign tax credit under
current law. Because application of the credit depends on the particular
circumstances of each shareholder, shareholders are advised to consult their own
tax advisers.

         THE FOREGOING IS ONLY A GENERAL SUMMARY OF CERTAIN PROVISIONS OF THE
CODE AND CURRENT TREASURY REGULATIONS APPLICABLE TO EACH FUND AND ITS
SHAREHOLDERS. THE CODE AND SUCH REGULATIONS ARE SUBJECT TO CHANGE BY LEGISLATIVE
OR ADMINISTRATIVE ACTION.

         THE TAX CONSEQUENCES TO A FOREIGN SHAREHOLDER OF A FUND MAYBE DIFFERENT
FROM THOSE DESCRIBED HEREIN. FOREIGN SHAREHOLDERS ARE ADVISED TO CONSULT THEIR
OWN TAX ADVISORS WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF AN
INVESTMENT IN A FUND.

         DISTRIBUTIONS TO YOU MAY ALSO BE SUBJECT TO STATE, LOCAL, AND FOREIGN
TAXES. WE URGE YOU TO CONSULT YOUR TAX ADVISORS REGARDING THE APPLICATION OF
FEDERAL, STATE, LOCAL, AND FOREIGN TAX LAWS.

                                   APPENDIX A

                      DESCRIPTION OF CORPORATE BOND RATINGS

MOODY'S INVESTORS SERVICES, INC. ("MOODY'S")

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

    AA - Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or 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.

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

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

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

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

    D - Debt rated D is in default, and payment of interest and/or repayment of
principal is in arrears.

    The ratings from "Aa" to "B" may be modified by the addition of a plus or
minus sign to indicate relative standing within the major rating categories.

STANDARD & POOR'S CORPORATION ("S&P")

    AAA:  Bonds rated AAA have the highest rating assigned by S&P. Capacity to
pay interest and repay principal is extremely strong.

    AA: Bonds rated AA have a very strong capacity to pay interest and repay
principal and differ from the higher rated issues only in small degree.

    A: Bonds rated A have a very strong capacity to pay interest and repay
principal although they are somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than bonds in higher rated
categories.

                                       46
<PAGE>

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

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

    Plus (+) or Minus (C): The ratings from "AA" to "BBB" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.

    Unrated: Indicates that no public rating has been requested, that there is
insufficient information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.

    Notes: Bonds which are unrated expose the investor to risks with respect to
capacity to pay interest or repay principal which are similar to the risks of
lower-rated speculative obligations. The Trust is dependent on the Adviser's
judgment, analysis and experience in the evaluation of such bonds.

                     DESCRIPTION OF COMMERCIAL PAPER RATINGS

    MOODY'S INVESTORS SERVICE, INC.: The following rating designations for
commercial paper (defined by Moody's as promissory obligations not having
original maturity in excess of nine months), are judged by Moody's to be
investment grade, and indicate the relative repayment capacity of rated issuers:

        PRIME-1: Superior capacity for repayment. Capacity will normally be
    evidenced by the following characteristics: (a) leveling market positions in
    well-established industries; (b) high rates of return on funds employed; (c)
    conservative capitalization structures with moderate reliance on debt and
    ample asset protection; (d) broad margins in earning coverage of fixed
    financial charges and high internal cash generation; and (e) well
    established access to a range of financial markets and assured sources of
    alternate liquidity.

        PRIME-2: Strong capacity for repayment. This will normally be evidenced
    by many of the characteristics cited above but to a lesser degree. Earnings
    trends and coverage ratios, while sound, will be more subject to variation.
    Capitalization characteristics, while still appropriate, may be more
    affected by external conditions Ample alternate liquidity is maintained.

    STANDARD & POOR'S CORPORATION: The following ratings by S&P for commercial
paper (defined by S&P as debt having an original maturity of no more than 365
days) assess the likelihood of payment:

       A-1: Strong capacity for timely payment. Those issues determined to
    possess extremely strong safety characteristics are denoted with a plus sign
    (+) designation.

       A-2:  Satisfactory capacity for timely payment. However, the relative
    degree of safety is not as high as for issues designated "A-1."

    FITCH INVESTORS SERVICE, INC. ("FITCH"): Fitch assigns the following
short-term ratings to debt obligations that are payable on demand or have
original maturities of generally up to three years, including commercial paper,
certificates of deposit, medium-term notes, and municipal and investment notes:

       F-1+: Exceptionally strong credit quality; the strongest degree of
    assurance for timely payment.

                                       47
<PAGE>

       F-1: Very strong credit quality, assurance of timely payment is only
    slightly less in degree than issues rated "F-1+".

       F-2: Good credit quality; satisfactory degree of assurance for timely
    payment, but the margin of safety is not as great as for issues assigned
    "F-l+" or "F-1" ratings.

    DUFF & PHELPS, INC. ("DUFF & PHELPS"): The following ratings are for
commercial paper (defined by Duff & Phelps as obligations with maturities, when
issued, of under one year), asset-backed commercial paper, and certificates of
deposit (the ratings cover all obligations of the institution with maturities,
when issued, of under one year, including bankers' acceptances and letters of
credit):
       DUFF 1+: Highest certainty of timely payment. Short-term liquidity,
    including internal operating factors and/or access to alternative sources of
    funds, is outstanding, and safety is just below risk-free U.S. Treasury
    short-term obligations.

       DUFF 1: Very high certainty of timely payment. Liquidity factors are
    excellent and supported by good fundamental protection factors. Risk factors
    are minor.

       DUFF 1C: High certainty of timely payment. Liquidity factors are strong
    and supported by good fundamental protection factors. Risk factors are very
    small.

       DUFF 2: Good certainty of timely payment. Liquidity factors and company
    fundamentals are sound. Although ongoing funding needs may enlarge total
    financing requirements, access to capital markets is good. Risk factors are
    small.

    IBCA LIMITED OR ITS AFFILIATE IBCA INC. ("IBCA"): Short-term ratings,
including commercial paper (with maturities up to 12 months), are as follows:

       AL+:  Obligations supported by the highest capacity for timely repayment.

       AL:  Obligations supported by a very strong capacity for timely
    repayment.

       A2: Obligations supported by a strong capacity for timely repayment,
    although such capacity may be susceptible to adverse changes in business,
    economic, or financial conditions.

    THOMSON BANKWATCH, INC. ("TBW"): The following short-term ratings apply to
commercial paper, certificates of deposit, unsecured notes, and other securities
having a maturity of one year or less:

       TBW-1: The highest category; indicates the degree of safety regarding
    timely repayment of principal and interest is very strong.

       TBW-2: The second highest rating category; while the degree of safety
    regarding timely repayment of principal and interest is strong, the relative
    degree of safety is not as high as for issues rated "TBW-1."
