The Potomac Funds (the "Trust") is a no-load management investment company, or
mutual fund, which consists of seven separate investment portfolios (the
"Funds"). The Funds are designed principally for experienced investors who
intend to follow a global asset allocation strategy. The Funds are not designed
for inexperienced or less sophisticated investors. An important feature of the
Trust is that it primarily consists of pairs of Funds, one of which attempts to
provide results correlating to a specific index, while the other attempts to
provide inverse performance that is similar to a short position in the specific
index. In particular, the following Funds seek investment results that
correspond over time to the following benchmarks:

                                 October 1, 1997
<PAGE>
        The Trust also offers the Potomac U.S. Government Money Market Fund,
which seeks security of principal, current income and liquidity by investing
primarily in money market instruments issued or guaranteed, as to principal and
interest, by the U.S. Government, its agencies or instrumentalities. THIS FUND
SEEKS TO MAINTAIN A CONSTANT $1.00 NET ASSET VALUE PER SHARE, ALTHOUGH THIS
CANNOT BE ASSURED.
        The Funds (other than the Potomac U.S. Government Money Market Fund) may
engage in certain aggressive investment techniques, which include engaging in
short sales and transactions in options and futures contracts. The Potomac U.S.
Plus Fund and the Potomac OTC Plus Fund may use the speculative technique known
as leverage to increase funds available for investment. See "Special Risk
Considerations." Investors in the Potomac Japan/Long Fund, Potomac U.S. Plus
Fund and Potomac OTC Plus Fund may experience substantial losses during
sustained periods of falling equity prices. Investors in the Potomac Japan/Short
Fund, Potomac U.S./Short Fund and Potomac OTC/Short Fund may experience
substantial losses during periods of sustained periods of rising equity prices.
None of the Funds alone constitutes a balanced investment plan, and investments
in certain of the Funds involve special risks not traditionally associated with
investment companies, including significant portfolio turnover. SHARES OF THE
POTOMAC U.S. GOVERNMENT MONEY MARKET FUND ARE NOT DEPOSITS OR OBLIGATIONS, OR
GUARANTEED OR ENDORSED BY, THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE
FEDERAL RESERVE BOARD OR ANY OTHER AGENCY. AN INVESTMENT IN THIS FUND IS NEITHER
INSURED NOR GUARANTEED BY THE UNITED STATES GOVERNMENT. See "Special Risk
Considerations." There can be no assurance that a Fund will achieve its
investment objective.

reference. This Prospectus is designed to set forth concisely the information an
investor should know about the Trust before investing. A Statement of Additional
Information ("SAI"), dated October 1, 1997, containing additional information

                               PROSPECTUS SUMMARY

THE POTOMAC FUNDS
        Each Fund has its own distinct investment objective. There is no
guarantee that any Fund will achieve its investment objective. The investment
objectives of the Funds are as follows.
        The POTOMAC JAPAN/LONG FUND ("Japan/Long Fund") seeks to provide
investment returns that correspond to the Nikkei 225 Stock Average ("Nikkei
Index"). The Nikkei Index is a price-weighted index of the 225 largest Japanese
companies listed on the Tokyo Stock Exchange. In attempting to achieve its
objective, the Fund may invest in securities included in that index and may
enter into long positions in Nikkei Index futures contracts, options on such
futures contracts and options on securities and on the Nikkei Index traded on
foreign and domestic exchanges. In addition, the Fund will use forward contracts
on Japanese Yen, futures contracts on Japanese Yen, options on such futures
contracts, and options on Japanese Yen to attempt to eliminate the effect that
fluctuations in the U.S. Dollar/Japanese Yen exchange rate may have on the
Fund's net asset value per share. The Fund also will invest in short-term 
debt securities.
        The POTOMAC JAPAN/SHORT FUND ("Japan/Short Fund") seeks to provide
investment returns that inversely correlate to the performance of the Nikkei
Index. If the Fund is successful in achieving its objective, the net asset value
of the Fund will increase in direct proportion to any decrease in the level of
the Nikkei Index and, conversely, the net asset value of the Fund will decrease
in direct proportion to any increase in the Nikkei Index. In attempting to
achieve its objective, the Fund may enter into short positions in Nikkei Index
futures contracts, options on such futures contracts and options on securities
and on the Nikkei Index traded on foreign and domestic exchanges. In addition,
the Fund will use forward contracts on Japanese Yen, futures contracts on
Japanese Yen, options on such futures contracts, and options on Japanese Yen to
attempt to eliminate the effect that fluctuations in the U.S. Dollar/Japanese
Yen exchange rate may have on the Fund's net asset value per share. The Fund
involves special risks not traditionally associated with investment companies.
Investors in this Fund may experience substantial losses during sustained
periods of rising Japanese equity prices. The Fund also will invest in
short-term debt securities.
<PAGE>
        The POTOMAC U.S. PLUS FUND ("U.S. Plus Fund") seeks to provide
investment returns that correspond to 150% of the performance of the Standard &
Poor's 500 Composite Stock Price IndexTM (the "S&P 500 Index"). In attempting to
achieve its objective, the Fund may invest in securities included in that index
and may enter into long positions in stock index futures contracts, options on
stock index futures contracts and options on securities and on stock indices. In
contrast to the returns of a mutual fund that seeks to approximate the return of
the S&P 500 Index, the Fund may produce gains greater than that return during
periods when the prices of securities included in the S&P 500 Index are rising
and below that return during periods when such prices are declining. Investors
in the Fund may experience substantial losses during sustained periods of
falling U.S. equity prices. The Fund also will invest in short-term debt
securities.
        The POTOMAC U.S./SHORT FUND ("U.S./Short Fund") seeks to provide
investment returns that inversely correlate to the performance of the S&P 500
Index. If the Fund is successful in meeting its objective, the Fund's net asset
value per share will increase in direct proportion to any decrease in the level
of the S&P 500 Index and, conversely, the net asset value of the Fund will
decrease in direct proportion to any increase in the level of the S&P 500 Index.
In seeking to achieve its objective, the Fund may enter into positions in stock
index futures contracts, options on stock index futures contracts and options on
securities and on stock indices. The Fund involves special risks not
traditionally associated with investment companies. Investors in the Fund may
experience substantial losses during sustained periods of rising U.S. equity
prices. The Fund also will invest in short-term debt securities.
        The POTOMAC OTC PLUS FUND ("OTC Plus Fund") seeks to provide investment
returns that correspond to 125% of the performance of the Nasdaq 100 IndexTM
("Nasdaq Index"). The Fund will invest in the securities included in that index,
as well as enter into long positions in stock index futures contracts, options
on such index futures contracts and options on securities and on stock indices.
In contrast to the returns of a mutual fund that seeks to approximate the return
of the Nasdaq Index, the Fund may produce gains greater than that return during
periods when prices of securities in the Nasdaq Index are rising and below that
return during periods when such prices are declining. Investors in the Fund may
experience substantial losses during sustained periods of falling U.S. equity
prices. The Fund also will invest in short-term debt securities.
        The POTOMAC OTC/SHORT FUND ("OTC/Short Fund") seeks to provide
investment results that will inversely correlate to the performance of the
Nasdaq Index. If the Fund is successful in meeting its objective, the Fund's net
asset value per share will increase in direct proportion to any decrease in the
level of the Nasdaq Index and, conversely, the net asset value of the Fund will
decrease in direct proportion to any increase in the level of the Nasdaq Index.
In seeking to achieve its objective, the Fund may enter into short positions in
stock index futures contracts, options on stock index futures contracts, and
options on securities and on stock indices. The Fund involves risks not
traditionally associated with investment companies. Investors in the Fund may
experience substantial losses during sustained periods of rising U.S. equity
prices. The Fund also will invest in short-term debt securities.
<PAGE>
        The POTOMAC U.S. GOVERNMENT MONEY MARKET FUND ("Money Market Fund")
seeks to provide security of principal, current income and liquidity. To achieve
its objective, the Money Market Fund invests primarily in money market
instruments that are issued or guaranteed as to principal and interest by the
U.S. Government, its agencies or instrumentalities, as well as in repurchase
agreements collateralized fully by U.S. Government securities.
        Further discussion of each Fund's investment objective and policies and
the risks associated with investing in the Funds may be found under "Investment
Objectives and Policies," "Special Risk Considerations" and "Investment
Techniques and Other Investment Policies" below.

SPECIAL RISK CONSIDERATIONS
        Each Fund (except the Money Market Fund) may engage in certain
aggressive investment techniques, which may include engaging in short sales and
transactions in futures contracts and options on securities, stock indices and
futures contracts. As discussed more fully under "Investment Objectives and
Policies," "Special Risk Considerations" and "Investment Techniques and Other
Investment Policies," these techniques are specialized and involve risks not
traditionally associated with investment companies.
        The Trust expects that a substantial number of the Funds' investors will
be experienced and will invest in the Funds as part of an asset allocation
investment strategy. These shareholders likely will redeem or exchange their
Fund shares frequently to take advantage of anticipated changes in market
conditions. The strategies employed by investors in the Funds may result in
considerable assets moving in and out of the Funds and, consequently, a high
portfolio turnover rate. A high portfolio turnover rate generally causes a Fund
to incur higher expenses and additional costs and may adversely affect the
ability of a Fund to meet its investment objective.
        Investors in the Japan/Long Fund and the Japan/Short Fund should be able
to assume the special risks of investing in foreign securities, which include
possible adverse political and economic developments abroad, fluctuations in
foreign currency values and differing character istics of foreign economies and
markets.
        The U.S. Plus Fund and the OTC Plus Fund may borrow money from banks for
investment purposes, which is a form of leveraging. This leverage may exaggerate
the gains and losses on a Fund's investments and the changes in a Fund's net
asset value per share. Each Fund may borrow money for temporary or emergency
purposes and to meet redemption requests without immediately selling portfolio
securities.
        While the Funds do not expect their returns over a twelve-month period
to deviate adversely from their respective current benchmarks by more than 10%,
certain factors may affect each Fund's ability to achieve this correlation.
        Under certain circumstances, trading on an exchange may be halted or
closed early, resulting in a Fund being unable to execute buy or sell orders
that day. If that occurs and a Fund needs to execute a high volume of trades on
that trading day, a Fund may incur substantial trading losses.
<PAGE>
PURCHASES, REDEMPTIONS, AND EXCHANGES OF TRUST SHARES
        The minimum initial investment is $10,000, which can be allocated in any
amounts among the Funds. The shares of each Fund may be purchased and redeemed
without any sales or redemption charges at the net asset value of the Fund next
determined. Exchanges must be for at least the lesser of $1,000 or the entire
account balance for the Fund from which the exchange is made. Shares of any Fund
may be exchanged at any time for shares of any other Fund, on the basis of the
relative net asset values next computed, without charge. Because of the
administrative expense of handling small accounts, the Trust reserves the right
to redeem involuntarily an investor's account, including a retirement account,
that falls below the minimum investment of $10,000 in total value in the Trust
due to redemptions. The Trust reserves the right to modify its minimum
investment requirements and the corresponding amounts below which an involuntary
redemption may be effected. See "How to Invest in the Funds," "Redeeming Shares
(Withdrawals)" and "Procedures for Redemptions and Exchanges."

INVESTMENT ADVISER
        Rafferty Asset Management, LLC ("Adviser") serves as the investment
adviser to each Fund. The Adviser is a newly created investment adviser and has
had no previous experience advising investment companies. Lawrence C. Rafferty
controls the Adviser.

                         FEES AND EXPENSES OF THE FUNDS

        Shown below are all expenses expected to be incurred by each Fund during
its initial fiscal year. Because each Fund's shares were not offered for sale

EXAMPLE
        Assuming a hypothetical investment of $1,000 in each Fund, a 5% annual 
return, and redemption at the end of each time period, an investor in each
Fund would pay transaction and operating expenses at the end of each period
as follows:

                           1 Year         3 Years
                          --------       --------
Japan/Long Fund              $15            $47
Japan/Short Fund             $17            $52
U.S. Plus Fund               $15            $47
U.S./Short Fund              $17            $52

Money Market Fund            $10            $32

        The preceding table of fees and expenses is provided to assist investors
in understanding the various costs and expenses that may be borne directly or
indirectly by an investor in each of the Funds. The assets of the Japan/Short
Fund, the U.S./Short Fund and the OTC/Short Fund may decline in a rising stock
market. During such periods, it is possible that the expense ratio of those
funds may increase. The 5% assumed annual return is for comparison purposes
only. THE FOREGOING EXAMPLES SHOULD NOT BE CONSIDERED A REPRESENTATION OF FUTURE
EXPENSES OR PERFORMANCE. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN
AND PERFORMANCE MAY BE BETTER OR WORSE THAN THE 5% ANNUAL RETURN ASSUMED IN THE
EXAMPLES. For additional information about the Funds' fees, see "Management and
Administration of the Trust" in this Prospectus and in the SAI.

================================================================================
                       INVESTMENT OBJECTIVES AND POLICIES

GENERAL
        The Funds are designed principally for experienced investors who intend
to follow an asset allocation investment strategy. The Funds are not designed
for inexperienced or less sophisticated investors. Except for the Money Market
Fund, each Fund is intended to provide investment exposure to a particular
segment of the domestic or international securities markets. These Funds seek
investment results that correspond over time to a specified benchmark. The terms
"long" and "short" in the Funds' names are not intended to refer to the duration
of the Funds' investment portfolios. The Funds may be used independently or in
combination with each other as part of an overall investment strategy.
Additional funds may be offered by the Trust from time to time.
        The Adviser uses a number of investment techniques in an effort to
correlate a Fund's return with the return of its respective benchmark. The
Adviser generally does not use fundamental securities analysis to accomplish
such correlation. Rather, the Adviser primarily uses statistical and
quantitative analysis to determine the investments a Fund makes and techniques
it employs. While the Adviser attempts to minimize any "tracking error" (the
statistical measure of the difference between the investment results of a Fund
and the performance of its benchmark), certain factors will tend to cause a
Fund's investment results to vary from a perfect correlation to its benchmark.
The Funds, however, do not expect that their total returns will vary from their
respective current benchmarks by more than 10% over a twelve-month period. See
"Special Risk Considerations - Tracking Error." It is the Funds' policy to
pursue their respective investment objectives regardless of market conditions,
to remain fully invested and not to take defensive positions.
<PAGE>
        Each Fund's investment objective and certain investment restrictions are
fundamental policies and may not be changed without the affirmative vote of at
least the majority of the outstanding shares of that Fund, as defined in the
Investment Company Act of 1940, as amended (the "1940 Act"). All other
investment policies of the Funds not specified as fundamental may be changed by
the Board of Trustees of the Trust ("Trustees" or the "Board") without
shareholder approval. There can be no assurance that a Fund will achieve its
objective. For a discussion of the instruments a Fund may use, see "Investment
Techniques and Other Investment Policies."

THE POTOMAC JAPAN/LONG FUND
        The investment objective of the Japan/Long Fund is to provide investment
returns that correspond to the performance of the Nikkei Index. In attempting to
achieve its objective, the Fund may enter into long positions in Nikkei Index
futures contracts, options on such futures contracts and options on securities
and on the Nikkei Index traded on domestic and foreign exchanges. Under the
investment techniques that the Fund employs, the Fund generally will incur a
loss if the price of the underlying security or index decreases between the date
of the employment of the technique and the date on which it terminates the
position. The amount of any gain or loss on these transactions may be affected
by any premium or interest income the Fund pays or receives as a result of the
transaction. The Fund may invest in the shares of individual securities that are
included in its benchmark. The Fund will use forward contracts on Japanese Yen,
futures contracts on Japanese Yen, options on such futures contracts and options
on Japanese Yen to attempt to eliminate the effect that fluctuations in the U.S.
Dollar/Japanese Yen exchange rate may have on the Fund's net asset value per
share. The Fund also may invest in U.S. Government securities in order to
deposit such securities as initial or variation margin, as "cover" for the
investment techniques it employs, as part of a cash reserve and for liquidity
purposes.

THE POTOMAC JAPAN/SHORT FUND
        The Japan/Short Fund is intended to allow investors to benefit from 
anticipated decreases in the Nikkei Index or to hedge an existing portfolio of
Japanese stocks. The Fund's investment objective is to provide investment
results that will inversely correlate to the performance of the Nikkei Index.
        If the Fund achieves a perfect inverse correlation for any single
trading day, the Fund's net asset value per share would increase for that day in
direct proportion to any decrease in the level of the Nikkei Index and,
conversely, the Fund's net asset value per share would decrease for that day in
direct proportion to any increase in the level of the Nikkei Index. For example,
if the Nikkei Index were to decrease by 1% by the close of business on a
particular trading day, investors in the Fund should experience a gain in net
asset value of approximately 1% for that day. Conversely, if the Nikkei Index
were to increase by 1% by the close of business on a particular trading day,
investors in the Fund should experience a loss in net asset value of
approximately 1% for that day.
        The Fund intends to pursue its investment objective regardless of market
conditions and does not intend to take defensive positions in anticipation of
rising Japanese equity prices. Consequently, investors in the Fund may
experience substantial losses during sustained periods of rising Japanese equity
prices.
<PAGE>
        In pursuing its investment objective, the Fund generally does not invest
in traditional equity securities, such as common stock. Rather, the Fund employs
certain investment techniques, including engaging in short sales and entering
into short positions in Nikkei Index futures contracts, options on such futures
contracts, and options on securities and on the Nikkei Index. See "Investment
Techniques and Other Investment Policies." Under these techniques, the Fund
generally will incur a loss if the price of the underlying security or index
increases between the date the Fund initially entered into the transaction and
the date on which the Fund terminates its position. The Fund generally will
realize a gain if the underlying security or index declines in price between
those dates. This result is the opposite of what one would expect from a cash
purchase of a long position in a security. In addition, the Fund will use
forward contracts on Japanese Yen, futures contracts on Japanese Yen, options on
such futures contracts and options on Japanese Yen to attempt to eliminate the
effect that fluctuations in the U.S. Dollar/Japanese Yen exchange rate may have
on the Fund's net asset value per share. The Fund also may invest in U.S.
Government securities in order to deposit such securities as initial or
variation margin, as "cover" for the investment techniques it employs, as part
of a cash reserve and for liquidity purposes.

THE POTOMAC U.S. PLUS FUND
        The investment objective of the U.S. Plus Fund is to provide investment
returns that correspond to 150% of the performance of the S&P 500 Index. In
attempting to achieve its objective, the Fund may enter into long positions in
stock index futures contracts, options on stock index futures contracts, and
options on securities and on stock indices. Under these techniques, the Fund
generally will incur a loss if the price of the underlying security or index
decreases between the date the Fund initially entered into the transaction and
the date on which the Fund terminates its position. The Fund also may invest in
shares of individual stocks that are included in its benchmark. The Fund also
may invest in U.S. Government securities in order to deposit such securities as
initial or variation margin, as "cover" for the investment techniques it
employs, as part of a cash reserve and for liquidity purposes.
        In contrast to a mutual fund that seeks to approximate the return of the
S&P 500 Index, the Fund may produce greater returns than such a fund during
periods when the prices of the securities in the S&P 500 Index are rising and
lower returns than such a fund during periods when the price of securities are
declining. Investors in the Fund may experience substantial losses during
sustained periods of falling U.S. equity prices.

THE POTOMAC U.S./SHORT FUND
        The U.S./Short Fund is intended to allow investors to benefit from
anticipated decreases in the S&P 500 Index or hedge an existing portfolio of
U.S. securities or mutual fund shares. The Fund's investment objective is to
provide investment results that will inversely correlate to the performance of
the S&P 500 Index.
        If the Fund achieves a perfect inverse correlation for any single
trading day, the net asset value of the Fund would increase for that day in
direct proportion to any decrease in the level of the S&P 500 Index and,
conversely, the net asset value of the Fund would decrease for that day in
direct proportion to any increase in the level of the S&P 500 Index. For
example, if the S&P 500 Index were to decrease by 1% by the close of business on
a particular trading day, investors in the Fund should experience a gain in net
asset value of approximately 1% for that day. Conversely, if the S&P 500 Index
were to increase by 1% by the close of business on a particular trading day,
investors in the Fund should experience a loss in net asset value of
approximately 1% for that day.

Government securities in order to deposit such securities as initial or

of a cash reserve and for liquidity purposes.

THE POTOMAC OTC PLUS FUND
        The investment objective of the OTC Plus Fund is to provide investment
results that correspond to 125% of the performance of the Nasdaq Index. The Fund
may not necessarily hold all 100 stocks included in the Nasdaq Index. Instead,
the Fund may hold representative stocks included in that index or other
securities that the Adviser believes will provide returns that correspond to
those of the Nasdaq Index. The Fund may enter into long positions in stock index
futures contracts, options on stock index futures, and options on securities and
on stock indices. Under these techniques, the Fund generally will incur a loss
if the price of the underlying security or index decreases between the date the
Fund initially entered into the transaction and the date on which the Fund
terminates its position. The Fund also may invest in U.S. Government securities
in order to deposit such securities as initial or variation margin, as "cover"
for the investment techniques it employs, as part of a cash reserve and for
liquidity purposes.
        Companies whose securities are traded on the over-the-counter ("OTC")
markets, which include the Nasdaq Stock Market ("Nasdaq"), generally are newer
companies or have smaller market-capitalization than those listed on the New
York Stock Exchange ("NYSE") or the American Stock Exchange ("AMEX"). OTC
companies often have limited product lines or relatively new products or
services, and may lack established markets, experienced management, financial
resources or the ability to raise capital. In addition, the securities of these
companies may have limited marketability and may be more volatile in price than
securities of larger capitalized and widely recognized companies. Among the
reasons for the greater price volatility of securities of certain small OTC
companies are less certain growth prospects of comparably smaller firms, the
lower degree of liquidity in the OTC markets for such securities and the greater
sensitivity of smaller capitalized companies to changing economic conditions
than larger capitalized, exchange-traded stocks. Conversely, the Adviser
believes that, because many of these OTC securities may be overlooked by
investors and undervalued in the marketplace, there is potential for significant
capital appreciation.
<PAGE>
        In contrast to a mutual fund that seeks to approximate the return of the
Nasdaq Index, the Fund may produce greater returns than such a fund during
periods when the prices of the securities in the Nasdaq Index are rising and
lower returns than such a fund during periods when the prices of securities are
declining. Investors in the Fund may experience substantial losses during
sustained periods of falling U.S. equity prices.

THE POTOMAC OTC/SHORT FUND
        The OTC/Short Fund is intended to allow investors to benefit from
anticipated decreases in the Nasdaq Index or hedge an existing portfolio of U.S.
securities or mutual fund shares. The Fund's investment objective is to provide
investment results that will inversely correlate to the performance of the
Nasdaq Index.
        If the Fund achieves a perfect inverse correlation for any single
trading day, the net asset value of the Fund would increase for that day in
direct proportion to any decrease in the level of the Nasdaq Index and,
conversely, the net asset value of the shares of the Fund would decrease for
that day in direct proportion to any increase in the level of the Nasdaq Index.
For example, if the Nasdaq Index were to decrease by 1% by the close of business
on a particular trading day, investors in the Fund should experience a gain in
net asset value of approximately 1% for that day. Conversely, if the Nasdaq
Index were to increase by 1% by the close of business on a particular trading
day, investors in the Fund should experience a loss in net asset value of
approximately 1% for that day.
        The Fund intends to pursue its investment objective regardless of market
conditions and does not intend to take defensive positions in anticipation of

generally will incur a loss if the price of the underlying security or index
increases between the date the Fund initially entered into the transaction and
the date on which the Fund terminates its position. The Fund generally will
realize a gain if the underlying security or index declines in price between
those dates. This result is the opposite of what one would expect from a cash
purchase of a long position in a security. The Fund also may invest in U.S.
Government securities in order to deposit such securities as initial or
variation margin, as "cover" for the investment techniques it employs, as part
of a cash reserve and for liquidity purposes.

THE POTOMAC U.S. GOVERNMENT MONEY MARKET FUND
        The investment objectives of the Money Market Fund are to provide
security of principal, current income, and liquidity. The Fund seeks to achieve
these objectives by investing in high quality, U.S. dollar-denominated
short-term obligations that have been determined by the Trustees or by the
Adviser, subject to supervision by the Trustees, to present minimal credit risk.
The Fund will invest exclusively in obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities ("U.S. Government Securities") and
repurchase agreements that are fully collateralized by such obligations.

================================================================================
                           SPECIAL RISK CONSIDERATIONS

        Investors should consider the following special notes in determining the
appropriateness of investing in the Funds.
        AGGRESSIVE INVESTMENT TECHNIQUES. Each Fund (other than the Money Market
Fund) may engage in certain aggressive investment techniques that may include
engaging in short sales and transactions in futures contracts and options on
securities, securities indices, and futures contracts. The Japan/Long Fund, the
Japan/Short Fund, the U.S. Plus Fund, the U.S./Short Fund and the OTC/Short Fund
will use these techniques primarily in seeking to achieve their investment
objectives. The OTC Plus Fund also will use these techniques in seeking to
achieve its investment objective. In doing so, a significant portion of these
Funds' assets will be held in an account consisting of cash or liquid assets as
"cover" for these investment techniques.
        The use of options, futures contracts, options on futures contracts,
forward contracts, swaps, caps, floors and collars, and the investment in
indexed securities, involves special risks, including (1) imperfect or no
correlation between the price of options and futures contracts and the movements
in the price of the underlying securities, indices, or futures contracts, (2)
possible lack of a liquid secondary market for any particular instrument at a
particular time, (3) the fact that the skills needed to use these strategies are
different from those needed to select portfolio securities, (4) losses due to
unanticipated market price movements, (5) incorrect forecasts by the Adviser
concerning interest or currency exchange rates or direction of price
fluctuations of the investment involved in the transaction, which may result in
the strategy being ineffective, (6) loss of premiums paid by a Fund on options
it purchases, and (7) the possible inability of a Fund to purchase or sell a
portfolio security at a time when it would otherwise be favorable for it to do
so, or the possible need for a Fund to sell a portfolio security at a
disadvantageous time, due to the need for the Fund to maintain "cover" or to
segregate assets in connection with such transactions and the possible inability
of a Fund to close out or liquidate its position.
<PAGE>
        These instruments may increase the volatility of a Fund and may involve
a small investment of cash relative to the magnitude of the risk assumed. In
addition, these instruments could result in a loss if the counterparty to the
transaction does not perform as promised or if there is not a liquid secondary
market to close out a position that a Fund has entered into.
        The ordinary spreads between prices in the cash and futures markets, due
to the differences in the natures of those markets, are subject to distortion.
Due to the possibility of distortion, a correct forecast of general interest
rates, currency exchange rates or stock market trends by the Adviser may still
not result in a successful transaction. The Adviser may be incorrect in its
expectations as to the extent of various interest or currency exchange rates or
stock market movements or the time span within which the movements take place.
        Options and futures transactions may increase portfolio turnover rates,
which results in correspondingly greater commission expenses and transaction
costs and may result in certain tax consequences.
        New financial products and risk management techniques continue to be
developed. Each Fund may use these instruments and techniques to the extent
consistent with its investment objective and regulatory requirements applicable
to investment companies. For further information regarding these techniques, see
"Investment Techniques and Other Investment Policies" below.
        PORTFOLIO TURNOVER. The Trust anticipates that investors in the Funds
frequently will redeem Fund shares, as well as exchange their Fund shares for
shares of another Fund. A Fund may have to dispose of certain investments in
order to maintain sufficient liquid assets to meet such redemption and exchange
requests, thereby causing a high portfolio turnover rate. Because each Fund's
portfolio turnover rate will depend largely on the purchase, redemption, and
exchange activity of its investors, it is difficult to estimate what each Fund's
actual turnover rate will be. Based on the formula prescribed by the SEC, the
portfolio turnover rate of each Fund is calculated without regard to securities,
including options and futures contracts, having a maturity of less than one
year. The Japan/Long Fund, the Japan/Short Fund, the U.S. Plus Fund, the
U.S./Short Fund, and the OTC/Short Fund typically will hold most of their
investments in options and futures contracts, which are excluded from the
portfolio turnover rate calculations. If, however, options and futures contracts
were included in such calculation, it is expected that the portfolio turnover
rate of each Fund would be approximately 500%. The OTC Plus Fund, which will
invest primarily in common stocks, is expected to have a similar rate.
        A higher portfolio turnover ratio would likely involve correspondingly
higher brokerage commissions and other expenses borne by a Fund. Such higher
expenses can adversely affect the ability of a Fund to achieve its investment
objective.
        FOREIGN SECURITIES. Investing in foreign companies may involve risks not
typically associated with investing in U.S. companies. The value of securities
denominated in foreign currencies, and of dividends from such securities, can
change significantly when foreign currencies strengthen or weaken relative to
the U.S. Dollar. Foreign securities markets generally have less trading volume
and less liquidity than U.S. markets, and prices in some foreign markets can be
extremely volatile. Many foreign countries lack uniform accounting and
disclosure standards comparable to those that apply to U.S. companies, and it
may be more difficult to obtain reliable information regarding a foreign
issuer's financial condition and operations. In addition, the costs of foreign
investing, including withholding taxes, brokerage commissions and custodial
fees, generally are higher than for U.S. investments.
<PAGE>
        BORROWING. The U.S. Plus Fund and the OTC Plus Fund may borrow money
from banks for investment purposes, which is a form of leveraging. This leverage
may exaggerate the gains and losses on a Fund's investments and on changes in a
Fund's net asset value. Leverage also creates interest expenses -- if those
expenses exceed the return on the transactions that the borrowings facilitate,
the Fund will be in a worse position than if it had not borrowed. The use of the
derivatives in connection with leverage may create the potential for significant
losses.
        TRACKING ERROR. While the Funds do not expect that their returns over a
twelve-month period will deviate adversely from their respective benchmarks by
more than 10%, several factors may affect the Funds' ability to achieve this
correlation. Among these factors are: (1) Fund expenses, including brokerage
expenses and commissions (which may be increased by high portfolio turnover);
(2) less than all of the securities in the benchmark being held by a Fund and
securities not included in the benchmark being held by a Fund; (3) an imperfect
correlation between the performance of instruments held by a Fund, such as
futures contracts and options, and the performance of the underlying securities
in the cash market comprising an index; (4) bid-ask spreads (the effect of which
may be increased by portfolio turnover); (5) a Fund holding instruments that are
illiquid or the market for which becomes disrupted; (6) the need to conform a
Fund's portfolio holdings to comply with that Fund's investment restrictions or
policies, or regulatory or tax law requirements and (7) market movements that
run counter to a leveraged Fund's investments (which will cause divergence
between the Fund and its benchmark over time due to the mathematical effects of
leveraging).
        Investors should be aware that while index futures and options contracts
closely correlate with the applicable indices over long periods, shorter-term
deviation, such as on a daily basis, does occur with these instruments. As a
result, a Fund's short-term performance will reflect such deviation from its
benchmark.
        In the case of the Funds whose net asset values move inversely from
their benchmarks -- the Japan/Short Fund, the U.S./Short Fund and the OTC/Short
Fund -- the factor of compounding also may lead to tracking error. Even if there
is a perfect inverse correlation between a Fund and the return of its applicable
benchmark on a daily basis, the symmetry between the changes in the benchmark
and the changes in the Fund's net asset value can be altered significantly over
time by a compounding effect. For example, if the Japan/Short Fund achieved a
perfect inverse correlation with the Nikkei Index on every trading day over an
extended period and the level of returns of the Nikkei Index significantly
decreased during that period, a compounding effect for that period would result,
causing an increase on the Japan/Short Fund's net asset value by a percentage
that is somewhat greater than the percentage the Nikkei Index returns decreased.
Conversely, if the Japan/Short Fund maintained a perfect inverse correlation
with the Nikkei Index over an extended period and if the level of returns of the
Nikkei Index significantly increased over that period, a compounding effect
would result, causing a decrease of the Japan/Short Fund's net asset value by a
percentage that would be somewhat less than the percentage the Nikkei Index
returns increased.
<PAGE>
        TRADING HALTS. All of the Funds, with the exception of the OTC Plus Fund
and the Money Market Fund, typically will hold most of their investments in
short-term options and futures contracts. The major exchanges on which these
contracts are traded, such as the Chicago Mercantile Exchange ("CME"), the
Chicago Board of Options Exchange ("CBOE"), the Singapore International Monetary
Exchange ("SIMEX") and the Osaka Securities Exchange, have established limits on
how much an option or futures contract may decline over various time periods
within a day. If an option or futures contract's price declines more than the
established limits, trading is halted on that instrument. If such trading halts
are instituted by an options or futures exchange at the close of a trading day,
a Fund will not be able to execute purchase or sales transactions in the
specific options or futures contracts affected. In such an event, a Fund also
would be unable to accurately price its outstanding contracts. A trading halt at
the end of a business day would constitute an emergency situation under SEC
regulations. A Fund affected by such an emergency would not be able to accept
investors' orders for purchases, redemptions, or exchanges received earlier
during the business day.
        EARLY NASDAQ CLOSINGS. The normal close of trading of securities listed
on the Nasdaq is 4:00 p.m. While an infrequent occurrence, trading on the Nasdaq
has closed as much as 15 minutes prior to the normal close because of computer
systems failures. Early closing of the Nasdaq may result in a Fund, particularly
the OTC Plus Fund and the OTC/Short Fund, being unable to execute buy or sell
orders on the Nasdaq that day. If that occurs and a Fund needs to execute a high
volume of trades late in a trading day, a Fund may incur substantial trading
losses.

                         INVESTMENT TECHNIQUES AND OTHER
                               INVESTMENT POLICIES

FUTURES CONTRACTS AND OPTIONS ON
FUTURES CONTRACTS
        Each Fund, other than the Money Market Fund, may purchase and sell stock
index futures contracts and options on such futures contracts. The Japan/Long
Fund and the Japan/Short Fund may also purchase and sell futures contracts on
Japanese Yen and options on such futures contracts. Each Fund, other than the
Money Market Fund, may purchase and sell futures and options thereon as a
substitute for a comparable market position in the underlying securities or
currency, to attempt to hedge or limit the exposure of its position, to create a
synthetic money market position, for certain tax-related purposes and to effect
closing transactions.
        A futures contract obligates the seller to deliver (and the purchaser to
take delivery of) the specified security or currency on the expiration date of
the contract. An index futures contract obligates the seller to deliver (and the
purchaser to take) an amount of cash equal to a specific dollar amount times the
difference between the value of a specific index at the close of the last
trading day of the contract and the price at which the agreement is made. No
physical delivery of the underlying securities in the index is made.
        When a Fund writes an option on a futures contract, it becomes
obligated, in return for the premium paid, to assume a position in the futures
contract at a specified exercise price at any time during the term of the
option. If a Fund writes a call, it assumes a short futures position. If it
writes a put, it assumes a long futures position. When the Fund purchases an
option on a futures contract, it acquires the right in return for the premium it
pays to assume a position in a futures contract (a long position if the option
is a call and a short position if the option is a put).
<PAGE>
        Whether a Fund realizes a gain or loss from futures activities depends
upon movements in the underlying security, currency or index. The extent of the
Fund's loss from an unhedged short position in futures contracts or from writing
unhedged call options on futures contracts is potentially unlimited. The Funds
will only purchase and sell futures contracts and options on futures contracts
that are traded on a U.S. exchange or board of trade or, in the case of the
Japan/Long and Japan/Short Funds, also on the Osaka Securities Exchange or
SIMEX.
        To the extent that a Fund enters into futures contracts, options on
futures contracts or options on foreign currencies traded on an exchange
regulated by the Commodity Futures Trading Commission ("CFTC"), in each case
other than for bona fide hedging purposes (as defined by the CFTC), the
aggregate initial margin and the premiums required to establish those positions
(excluding the amount by which options are "in-the-money" at the time of
purchase) will not exceed 5% of the liquidation value of the Fund's portfolio,
after taking into account unrealized profits and unrealized losses on any
contracts the Fund has entered into. (In general, a call option on a futures
contract is "in-the-money" if the value of the underlying futures contract
exceeds the strike, i.e., exercise, price of the call. A put option on a futures
contract is "in-the-money" if the value of the underlying futures contract is
exceeded by the strike price of the put.) This policy does not limit to 5% the
percentage of a Fund's assets that are at risk in futures contracts, options on
futures contracts and currency options.

OPTIONS ON INDICES, SECURITIES AND CURRENCIES
        Each Fund, other than the Money Market Fund, may purchase and sell put
and call options on stock indices and on individual securities. The Japan/Long
Fund and the Japan/Short Fund may also purchase and sell put and call options on
Japanese Yen. Each Fund, other than the Money Market Fund, may purchase and sell
put and call options as a substitute for a comparable market position in the
underlying securities or currency, to attempt to hedge or limit the exposure of
its position, to create a synthetic money market position, for certain
tax-related purposes and to effect closing transactions.
        An index fluctuates with changes in the market values of the securities
included in the index. Options on indices give the holder the right to receive
an amount of cash upon exercise of the option. Receipt of this cash amount will
depend upon the closing level of the index upon which the option is based being
greater than (in the case of a call) or less than (in the case of a put) the
exercise price of the option. The amount of cash received, if any, will be the
difference between the closing price of the index and the exercise price of the
option, multiplied by a specified dollar multiple. The writer (seller) of the
option is obligated, in return, for the premium received from the purchaser of
the option, to make delivery of this amount to the purchaser. Unlike the option
on securities discussed below, all settlements of index options transactions are
in cash.
        Some stock index options are based on a broad market index such as the
S&P 500 Index, the NYSE Composite Index or the AMEX Major Market Index, or on a
narrower index such the Philadelphia Stock Exchange Over-the-Counter Index.
Options currently are traded on the CBOE, the AMEX and other exchanges. Options
also are traded in the OTC markets and each Fund may buy and sell both
exchange-traded and OTC options.
<PAGE>
        Each of the exchanges has established limitations governing the maximum
number of call or put options on the same index that may be bought or written by
a single investor, whether acting alone or in concert with others (regardless of
whether such options are written on the same or different exchanges or are held
or written on one or more accounts or through one or more brokers). Under these
limitations, option positions of all investment companies advised by the same
investment adviser are combined for purposes of these limits. Pursuant to these
limitations, an exchange may order the liquidation of positions and may impose
other sanctions or restrictions. These positions limits may restrict the number
of listed options that a Fund may buy or sell.
        By buying a call option on a security or currency, a Fund has the right,
in return for the premium paid, to buy the security or currency underlying the
option at the exercise price. By writing (selling) a call option and receiving a
premium, a Fund becomes obligated during the term of the option to deliver
securities or currency underlying the option at the exercise price if the option
is exercised. By buying a put option, a Fund has the right, in return for the
premium, to sell the security or currency underlying the option at the exercise
price. By writing a put option, a Fund becomes obligated during the term of the
option to purchase the securities or currency underlying the option at the
exercise price.
        Because options premiums paid or received by a Fund are small in
relation to the market value of the investments underlying the options, buying
and selling put and call options can be more speculative than investing directly
in securities.

FORWARD CONTRACTS AND FOREIGN CURRENCY
        Both the Japan/Long Fund and the Japan/Short Fund may enter into forward
currency contracts for the purchase or sale of Japanese Yen at a specified
future date to attempt to eliminate the effect that fluctuations in the U.S.
Dollar/Japanese Yen exchange rate may have on the Fund's net asset value per
share. Forward currency contracts are traded directly between currency traders
(usually large commercial banks) and their customers.
        These Funds also may purchase and sell foreign currency and invest in
foreign currency deposits. Currency conversion involves dealer spreads and other
costs, although commissions usually are not charged.

INDEXED SECURITIES
        Each Fund (other than the Money Market Fund) may purchase indexed
securities, which are securities the value of which varies positively or
negatively in relation to the value of other securities, securities indices,
currencies or other financial indicators, consistent with its investment
objective. Indexed securities typically, but not always, are debt securities or
deposits whose value at maturity or coupon rate is determined by reference to a
specific instrument or statistic. The performance of indexed securities depends
to a great extent on the performance of the security, currency or other
instrument to which they are indexed and also may be influenced by interest rate
changes in the United States and abroad. At the same time, indexed securities
are subject to the credit risks associated with the issuer of the security, and
their values may decline substantially if the issuer's creditworthiness
deteriorates. Indexed securities may be more volatile than the underlying
instruments.

SWAPS, CAPS, FLOORS AND COLLARS
        A Fund (other than the Money Market Fund) may enter into equity swaps,
caps, floors and collars. For example, the Japan/Long Fund, the U.S. Plus Fund
and the OTC Plus Fund may enter into equity swaps where the Fund receives a
return based on the increase in value of a specified index, and pays the
counterparty an amount based on a floating rate of interest, on the notional
amount of the swap. The Japan/Short Fund, the U.S./Short Fund and the OTC/Short
Fund may enter into reverse equity swaps where the Fund receives a floating rate
of interest, and pays an amount equal to the increase in value of a specified
index, on the notional amount of the swap. The Japan/Long Fund and the
Japan/Short Fund also may use swaps, caps, floors and collars where a payment
stream is payable in Japanese Yen or is based on the U.S. Dollar/Japanese Yen
exchange rate. Each Fund (other than the Money Market Fund) may use equity
swaps, caps, floors and collars consistent with its investment objective and
also may enter into offsetting positions.
<PAGE>
        Swaps involve the exchange by a Fund with another party of their
respective commitments to pay or receive cash flows, e.g., an exchange of
payments based on the increase in value of an equity index for floating interest
rate payments. The purchase of a cap entitles the purchaser, to the extent that
a specified index exceeds a predetermined value, to receive payments on a
notional principal amount from the party selling such cap. The purchase of a
floor entitles the purchaser, to the extent that a specified index falls below a
predetermined value, to receive payments on a notional principal amount from the
party selling such floor. A collar combines elements of buying a cap and selling
a floor.
        A Fund usually will enter into swaps on a net basis, i.e., the two
payment streams are netted out, with the Fund receiving or paying, as the case
may be, only the net amount of the two payments. If, however, an agreement calls
for payments by a Fund, the Fund must be prepared to make such payments when
due. The creditworthiness of firms with which a Fund enters into swaps, caps,
floors or collars will be monitored by the Adviser in accordance with procedures
adopted by the Trustees. If a firm's creditworthiness declines, the value of an
agreement would be likely to decline, potentially resulting in losses. If a
default occurs by the other party to such transaction, a Fund will have
contractual remedies pursuant to the agreements related to the transaction.

SHORT SALES
        The Japan/Short Fund, the U.S./Short Fund and the OTC/Short Fund may
engage in short sales transactions under which the Fund sells a security it does
not own. To complete such a transaction, the Fund must borrow the security to
make delivery to the buyer. The Fund then is obligated to replace the security
borrowed by purchasing the security at the market price at the time of
replacement. The price at such time may be more or less than the price at which
the security was sold by the Fund. Until the security is replaced, the Fund is
required to pay to the lender amounts equal to any dividends that accrue during
the period of the loan. The proceeds of the short sale will be retained by the
broker, to the extent necessary to meet the margin requirements, until the short
position is closed out.
        Until a Fund closes its short position or replaces the borrowed stock,
the Fund will: (1) maintain an account containing cash or liquid assets at such
a level that (a) the amount deposited in the account plus that amount deposited
with the broker as collateral will equal the current value of the stock sold
short and (b) the amount deposited in the account plus the amount deposited with
the broker as collateral will not be less than the market value of the stock at
the time the stock was sold short; or (2) otherwise cover the Fund's short
position.
<PAGE>
        The Japan/Long Fund, the U.S. Plus Fund and the OTC Plus Fund each may
engage in short sales if, at the time of the short sale, the Fund owns or has
the right to acquire an equal amount of the stock being sold at no additional
cost ("selling short against the box").

FOREIGN SECURITIES
        The Japan/Long Fund and the Japan/Short Fund may invest in issuers
located outside the United States. These investments may be made by purchasing
American Depository Receipts ("ADRs"), "ordinary shares" or "New York" shares in
the United States. The Japan/Short Fund also may sell these securities short.
        ADRs are dollar denominated receipts representing interests in the
securities of a foreign issuer, which securities may not necessarily be
denominated in the same currency as the securities into which they may be
converted. ADRs are receipts typically issued by United States banks and trust
companies that evidence ownership of underlying securities issued by a foreign
corporation. Generally, ADRs in registered form are designed for use in domestic
securities markets and are traded on exchanges or OTC in the United States.
Ordinary shares are shares of foreign issuers that are traded abroad and on a
U.S. exchange. New York shares are shares that a foreign issuer has allocated
for trading in the United States. ADRs, ordinary shares and New York shares all
may be purchased with and sold for U.S. Dollars.
        Investing in companies located abroad carries political and economic
risks distinct from those associated with investing in the United States.
Foreign investments may be affected by actions of foreign governments adverse to
the interests of U.S. investors, including the possibility of expropriation or
nationalization of assets, confiscatory taxation, restrictions on U.S.
investment, or on the ability to repatriate assets or to convert currency into
U.S. dollars. There may be a greater possibility of default by foreign
governments or foreign-government sponsored enterprises. Investments in foreign
countries also involve a risk of local political, economic, or social
instability, military action or unrest, or adverse diplomatic developments.

U.S. GOVERNMENT SECURITIES
        The Money Market Fund will invest in U.S. Government Securities in
pursuit of its investment objectives. The other Funds may invest in U.S.
Government Securities in order to deposit such securities as initial or
variation margin, as "cover" for the investment techniques they employ, as part
of a cash reserve and for liquidity purposes. U.S. Government Securities include
direct obligations of the U.S. Treasury (such as Treasury bills, Treasury notes
and Treasury bonds).
        U.S. Government Securities are high-quality instruments issued or
guaranteed as to principal or interest by the U.S. Treasury or by an agency or
instrumentality of the U.S. Government. Not all U.S. Government Securities are
backed by the full faith and credit of the United States. Some are backed by the
right of the issuer to borrow from the U.S. Treasury; others are backed by
discretionary authority of the U.S. Government to purchase the agencies'
obligations; while others are supported only by the credit of the
instrumentality. In the case of securities not backed by the full faith and
credit of the United States, the investor must look principally to the agency
issuing or guaranteeing the obligation for ultimate repayment.
        Yields on short-, intermediate- and long-term U.S. Government Securities
are dependent on a variety of factors, including the general conditions of the
money and bond markets, the size of a particular offering and the maturity of
the obligation. Debt securities with longer maturities tend to produce higher
capital appreciation and depreciation than obligations with shorter maturities
and lower yields. The market value of U.S. Government Securities generally
varies inversely with changes in the market interest rates. An increase in
interest rates, therefore, generally would reduce the market value of a Fund's
portfolio investments in U.S. Government Securities; while a decline in interest
rates generally would increase the market value of a Fund's portfolio
investments in these securities.
<PAGE>
REPURCHASE AGREEMENTS
        Under a repurchase agreement, a Fund purchases a U.S. Government
Security and simultaneously agrees to sell the security back to the seller at a
mutually agreed-upon future price and date, normally one day or a few days
later. The resale price is greater than the purchase price, reflecting an
agreed-upon market interest rate during the Fund's holding period. While the
maturities of the underlying securities in repurchase agreement transactions may
be more than one year, the term of each repurchase agreement always will be less
than one year. Each Fund may enter into repurchase agreements with banks that
are members of the Federal Reserve System or securities dealers who are members
of a national securities exchange or are primary dealers in U.S. Government
Securities. The Adviser will monitor the creditworthiness of each firm that is a
party to a repurchase agreement with any Fund. In the event of default or
bankruptcy by the seller, the Fund will liquidate those securities (whose market
value, including accrued interest, must be at least 100% of the amount invested
by the Fund) held under the applicable repurchase agreement, which securities
constitute collateral for the seller's obligation to repurchase the security.
ILLIQUID INVESTMENTS
        Each Fund may purchase and hold illiquid investments, including
securities that are not readily marketable and securities that are not
registered ("restricted securities") under the Securities Act of 1933, as
amended ("1933 Act"), but which can be offered and sold to "qualified
institutional buyers" pursuant to Rule 144A under the 1933 Act. A Fund will not
invest more than 15% (10% with respect to the Money Market Fund) of its net
assets in illiquid investments. The term "illiquid investments" for this purpose
means investments that cannot be disposed of within seven days in the ordinary
course of business at approximately the amount at which a Fund has valued the
investments. Under the current SEC staff guidelines, illiquid investments also
include purchased OTC options, certain cover for OTC options, securities
involved in swap, cap, floor and collar transactions, repurchase agreements not
terminable in seven days and restricted securities not determined to be liquid
pursuant to guidelines established by the Trustees.

OTHER INVESTMENT PRACTICES

        The U.S. Plus Fund and the OTC Plus Fund may borrow for investment
purposes. Each Fund may borrow money as a temporary measure for extraordinary or
emergency purposes and to meet redemption requests without immediately selling
portfolio securities. In addition, each Fund may lend securities to
broker-dealers and financial institutions, provided that the borrower at all
times maintains collateral in an amount equal to at least 100% of the market
value of the securities loaned. Such loans will not be made if, as a result, the
aggregate amount of all outstanding loans by any Fund would exceed 33 1/3% (10%
in the case of the Money Market Fund) of its total assets. For a more detailed
discussion of these practices, see the SAI.
<PAGE>
================================================================================
                      PORTFOLIO TRANSACTIONS AND BROKERAGE

        The Adviser will place orders to execute securities transactions that
are designed to implement each Fund's investment objective and policies. In
placing such orders, the Adviser will seek the most favorable price and
efficient execution available. In order to obtain brokerage and research
services, however, a higher commission sometimes may be paid. Brokerage
commissions normally are paid on exchange-traded securities transactions and on
options and futures transactions.
        When selecting a broker or dealer to execute portfolio transactions, the
Adviser considers many factors, including the rate of commission or the size of
the broker-dealer's "spread," the size and difficulty of the order, the nature
of the market for the security, operational capabilities of the broker-dealer
and the research, statistical and economic data furnished by the broker-dealer
to the Adviser. The Adviser may select one broker-dealer over another based on
whether the broker-dealer provides research services to the Adviser.


================================================================================
                           HOW TO INVEST IN THE FUNDS

GENERAL
        The minimum initial investment is $10,000, which can be allocated in any
amounts among the Funds. The shares of each Fund are offered at the daily public
offering price, which is the net asset value per share next computed after
receipt of the investor's order. See "Determination of Net Asset Value." No
sales charges are imposed on initial or subsequent investments in a Fund. The
Trust reserves the right to reject or refuse, at the Trust's discretion, any
order for the purchase of a Fund's shares in part or whole.
The minimum amount for subsequent investments in a Fund is $1,000.
        Investments in the Funds may be made
(1) through securities dealers who have the responsibility to transmit orders
promptly and who may charge a processing fee or (2) directly with the Trust
either by mail or bank wire transfer to the Trust's transfer agent, Firstar
Trust Company ("Transfer Agent") as described below.

BY MAIL
        You may purchase shares of a Fund directly by completing and signing the
Account Application included with the Prospectus and making out a check payable
to "Potomac Funds." Your investment will be allocated among the Funds as you
specify on the Account Application. Mail the check, along with the completed
Account Application, to Potomac Funds, c/o Firstar Trust Company, P.O. Box 1993,
Milwaukee, Wisconsin 53201-1993.
        Completed Account Applications and checks also may be sent by overnight
or express mail. To ensure proper delivery, please use the following address:
Potomac Funds, c/o Firstar Trust Company, Mutual Fund Services, 3rd Floor, 615
East Michigan Street, Milwaukee, Wisconsin 53202.
        Third-party checks will not be accepted by the Funds. All purchases 
must be in U.S. Dollars. A $20.00 fee will be imposed by the Transfer Agent if
any check used for investment in an account does not clear due to 
insufficient funds.
<PAGE>
BY BANK WIRE TRANSFER
        To establish a new account by wire transfer, please call the Transfer
Agent at (800) 851-0511 to obtain a Potomac Funds account number. You must send
a completed Account Application to
the Trust at the above address immediately following the investment. Payment for
Fund shares should be wired through the Federal Reserve System as follows:

        Firstar Bank Milwaukee, N.A.
        777 East Wisconsin Avenue
        Milwaukee, Wisconsin 53202
        ABA number 0750-00022
        For credit to Firstar Trust Company
        Account Number 112-952-137
        For further credit to the Potomac Funds
        Shareholder name: ___________________
        Shareholder account number: ___________

        Your bank may charge a fee for such services. If the purchase is
        canceled because your wire transfer is not received, you may be liable
        for any loss the Trust may incur. Physical certificates representing a
        Fund's shares are not issued. Shares of each Fund are recorded on a
        register by the Transfer Agent.


================================================================================
                         TAX-SHELTERED RETIREMENT PLANS

        The Trust offers individual retirement accounts ("IRAs") that may be
funded with purchases of Fund shares and may allow investors to shelter or defer
some of their income from taxes. A description of applicable service fees and
certain limitations on contributions and withdrawals, as well as Application
Forms, are available from the Trust upon request.

================================================================================
                         REDEEMING SHARES (WITHDRAWALS)

GENERAL
        You may withdraw all or any part of your investment by redeeming Fund
shares at the next determined net asset value per share after receipt of the
order. The amount received will depend on the market value of the investments in
a Fund's portfolio at the time of determination of net asset value. Shares of
the Funds may be redeemed by written request or by telephone to the Transfer
Agent subject to the procedures described below. When you redeem shares over the
telephone, those redemption proceeds will be sent only to your address of record
or to a bank account specified in your Account Application. In addition,
redemption proceeds may be sent by wire transfer to a bank account specified in
your Account Application. The minimum amount of a wire transfer redemption is
$5,000. You will be charged $12.00 for wire redemptions to cover transaction
costs.
        If you request payment of redemption proceeds to a third party or to a
location other than your address of record or a bank account specified in the
Account Application, your request must be in writing and your signature
guaranteed. In addition, if you request in writing redemption of $100,000 or
more, your signature must be guaranteed. A signature guarantee will be accepted
from a commercial bank, savings association, securities broker or dealer, or
credit union. A notary public cannot provide a signature guarantee.
        Payment of redemption proceeds will be made within seven days following
a Fund's receipt of your request for redemption. For investments that have been
made by check, payment on redemption requests may be delayed until the Transfer
Agent is reasonably satisfied that the purchase payment has been collected by
the Trust (which may require up to 10 business days). To avoid redemption
delays, purchases may be made by cashiers or certified check or by direct wire
transfers.
<PAGE>
        With respect to the U.S. Plus Fund, the U.S./Short Fund, the OTC Plus
Fund, the OTC/Short Fund and the Money Market Fund, the right of redemption may
be suspended or the date of payment postponed for any period during which the
NYSE, the Nasdaq, the CME, or the CBOE, or the Federal Reserve Bank of New York,
as appropriate, is closed (other than customary weekend or holiday closings) or
trading on the NYSE, the Nasdaq, the CME, or the CBOE, as appropriate, is
restricted. With respect to the Japan/Long Fund and the Japan/Short Fund, the
right of redemption may be suspended or the date of payment postponed for any
period during which the SIMEX or the Osaka Securities Exchange is closed (other
than customary weekend or holiday closings) or trading on that exchange is
restricted. In addition, the rights of redemption may be suspended or the date
of payment postponed for any Fund for a period during which an emergency exists
so that disposal of the Fund's investments or the determination of its net asset
value is not reasonably practicable or for such periods as the SEC, by order,
may permit for protection of a Fund's investors.

DRAFT CHECKS
        Checkwriting privileges are available to investors in the Money Market
Fund. With a Money Market Fund checking account, shares may be redeemed simply
by writing a check for $500 or more. The redemption will be made at the net
asset value next determined after the Transfer Agent presents the check to the
Money Market Fund. A check should not be written to close an account. There is a
$20 charge for each stop payment request on Money Market Fund checks. You are
subject to the same rules and regulations that banks apply to checking accounts.

LOW BALANCE ACCOUNTS
        Because of the high cost of maintaining accounts with low balances, it
is the Trust's policy to redeem involuntarily Fund shares in any account,
including a retirement account, if the account balance falls below $10,000 in
total value in the Trust. This policy does not apply to accounts that fall below
the minimum balance due to market fluctuations. The Trust will provide 30 days'
written notice to all such shareholders to bring the account balance up to the
minimum investment required or the Trust may redeem shares in the account and
pay the proceeds to the shareholder. A redemption from a tax-qualified
retirement plan may have adverse tax consequences and a shareholder
contemplating such a redemption should consult his or her tax adviser.


================================================================================
                                    EXCHANGES

        Shares of a Fund may be exchanged, without any charge, for shares of any
other Fund on the basis of the respective net asset values of the shares
involved. Exchanges may be effected by written request or by telephone to the
Transfer Agent subject to the procedures described below. Exchanges must be for
at least the lesser of $1,000 or the entire account balance for the Fund from
which the exchange is made.
        When you exchange shares from one Fund to another, your investment may
be uninvested in shares of a Fund until that Fund's next determined net asset
value. For example, if you exchange shares from the Japan/Short Fund to the U.S.
Plus Fund, your investment will be uninvested from 1:15 a.m., the time the
Japan/Short Fund determines net asset value, until 4:15 p.m., the time the U.S.
Plus Fund next determines its net asset value. See "Determination of Net Asset
Value" below.
<PAGE>
================================================================================
                    PROCEDURES FOR REDEMPTIONS AND EXCHANGES

GENERAL
        In requesting a redemption or exchange, you should provide your account
name, account number, the number of or percentage of shares or the dollar value
of shares to be exchanged or redeemed, as applicable, and the names of the Funds
involved. Exchanges may only be made between identically registered accounts. In
addition, any written request must be signed by a shareholder and all co-owners
of the account with exactly the same name or names used in establishing the
account.

BY MAIL
        Requests for redemptions and exchanges may be made in writing and
directed to the Potomac Funds, c/o Firstar Trust Company, P.O. Box 1993
Milwaukee, Wisconsin 53201-1993. Any such requests sent overnight or express
mail should be directed to the Potomac Funds, c/o Firstar Trust Company, Mutual
Fund Services, 3rd Floor, 615 East Michigan Street, Milwaukee, Wisconsin 53202.

BY TELEPHONE
        You may redeem or exchange Fund shares by calling the Transfer Agent at
(800) 851-0511. Shares may be redeemed by telephone only if your Account
Application reflects that option. Telephone requests may be made only between
9:00 a.m., Eastern time, and the times listed below. For telephone exchanges,
the closing time is the earlier closing time below of the two Funds involved in
the exchange:

        Japan/Long Fund           4:00 p.m.
        Japan/Short Fund          4:00 p.m.
        U.S. Plus Fund            3:40 p.m.
        U.S./Short Fund           3:40 p.m.
        OTC Plus Fund             3:40 p.m.
        OTC/Short Fund            3:40 p.m.
        Money Market Fund         4:00 p.m.

TELEPHONE REDEMPTION AND EXCHANGE ORDERS WILL BE ACCEPTED ONLY DURING THE
PERIODS INDICATED ABOVE.
        By establishing such telephone services, you authorize the Funds or
their agents to act upon verbal instructions to redeem or exchange Fund shares
for any account for which such service has been authorized. In an effort to
prevent unauthorized or fraudulent telephone transaction requests, the transfer
agent will employ reasonable procedures specified by the Funds to confirm that
such instructions are genuine. For instance, the Transfer Agent will require
some form of personal identification prior to acting upon telephone
instructions, provide written confirmation after such transactions, and record
telephone instructions. When acting on instructions believed to be genuine, the
Trust, Adviser, Transfer Agent and their trustees, directors, officers and
employees are not liable for any loss resulting from a fraudulent telephone
transaction request and the investor will bear the risk of loss. To the extent
that the Trust, Adviser, Transfer Agent and their trustees, directors, officers
and employees do not employ such procedures, some or all of them may be liable
for losses due to unauthorized or fraudulent transactions. You also should be
aware that telephone redemption or exchanges may be difficult to implement in a
timely manner during periods of drastic economic or market changes. If such
conditions occur, redemption or exchange orders can be made by mail.
<PAGE>
================================================================================
                        DETERMINATION OF NET ASSET VALUE

        The net asset value per share of the U.S. Plus Fund, the U.S./Short
Fund, the OTC Plus Fund and the OTC/Short Fund is determined as of 4:15 p.m.
Eastern time, 15 minutes after the close of normal trading on the NYSE
(currently 4:00 p.m., Eastern time) each day the NYSE is open for business. The
net asset value per share of the Japan/Long Fund and the Japan/Short Fund is
determined as of 1:15 a.m., Eastern time, 15 minutes after the close of normal
trading on the SIMEX (currently 1:00 a.m., Eastern time) each day that exchange
is open for business. The Money Market Fund's net asset value per share is
determined as of 1:00 p.m., Eastern time, each day that both the NYSE and the
Federal Bank of New York are open for business.
        Purchase, redemption and exchange requests for the Japan/Long Fund and
the Japan/Short Fund properly received by the Transfer Agent by 4:00 p.m.,
Eastern time, on Monday through Thursday are priced based on the net asset value
determined at 1:15 a.m., Eastern time, 15 minutes after the close of regular
trading on the SIMEX on the following day. Requests received by the Transfer
Agent prior to 4:00 p.m., Eastern time, on a Friday will be effected at the net
asset value determined as of the close of regular trading on the SIMEX on the
following Monday.
        A Fund's net asset value serves as the basis for the purchase and
redemption price of its shares. The net asset value per share of a Fund is
calculated by dividing the market value of the Fund's securities plus the value
of its other assets, less all liabilities, by the number of outstanding shares
of the Fund. If market quotations are not readily available, a security will be
valued at fair value by the Trustees or by the Adviser using methods established
or ratified by the Trustees.
        The Money Market Fund will utilize the amortized cost method in valuing
its portfolio securities. This method involves valuing a security at its cost
adjusted by 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. The purpose of this method of calculation is to facilitate the
maintenance of a constant net asset value per share for the Money Market Fund of
$1.00. However, there is no assurance that the $1.00 net asset value per share
will be maintained. For further information on valuing the Money Market Fund's
portfolio securities, see "Determination of Net Asset Value" in the SAI.
        For purposes of determining net asset value per share of a Fund, options
and futures contracts are valued at the closing prices of the exchanges on which
they trade. The value of a futures contract equals the unrealized gain or loss
on the contract that is determined by marking the contract to the current
settlement price for a like contract acquired on the day on which the futures
contract is being valued. The value of options on futures contracts is
determined based upon the current settlement price for a like option acquired on
the day on which the option is being valued. A settlement price may not be used
for the foregoing purposes if the market makes a limited move with respect to a
particular commodity.
<PAGE>
        OTC securities held by a Fund shall be valued at the last sales price
or, if no sales price is reported, the mean of the last bid and asked price is
used. The portfolio securities of a Fund that are listed on national exchanges
or foreign stock exchanges are valued at the last sales price of such
securities; if no sales price is reported, the mean of the last bid and asked
price is used. For valuation purposes, all assets and liabilities initially
expressed in foreign currency values will be converted into U.S. Dollars at the
mean between the bid and offered quotations of such currencies against U.S.
Dollars as last quoted by a recognized dealer. Dividend income and other
distributions are recorded on the ex-distribution date, except for certain
dividends from foreign securities that are recorded as soon as the Trust is
informed after the ex-distribution date.
        Illiquid securities, securities for which reliable quotations or pricing
services are not readily available, and all other assets not valued in
accordance with the foregoing principles will be valued at their respective fair
value as determined in good faith by, or under procedures established by, the
Trustees, which procedures may include the delegation of certain
responsibilities regarding valuation to the Adviser or the officers of the
Trust. The officers of the Trust report, as necessary, to the Trustees regarding
portfolio valuation determinations. The Trustees, from time to time, will review
these methods of valuation and will recommend changes that may be necessary to
assure that the investments of the Funds are valued at fair value.

================================================================================
                             PERFORMANCE INFORMATION

TOTAL RETURN
        From time to time each Fund may advertise its average annual total
return and compare its performance to that of other mutual funds with similar
investment objectives and to relevant indices. Performance information is
computed separately for those Funds in accordance with the methods discussed
below.
        Each Fund may include the total return of its shares in advertisements
or other written material. When a Fund advertises the total return of its
shares, it will be calculated for the one-, five-, and ten-year periods or, if
such periods have not yet elapsed, the period since the establishment of that
Fund. Total return is measured by comparing the value of an investment in a Fund
at the beginning of the relevant period to the redemption value of the
investment in that Fund at the end of the period (assuming reinvestment of any
dividends capital gain distributions at net asset value). For more information
on Fund performance, see "Performance Information" in the SAI.

YIELD
        From time to time the Money Market Fund may advertise "yield" and
"effective yield." The Money Market Fund's yield figure is based on historical
earnings and is not intended to indicate future performance. The yield of the
Money Market Fund refers to the income generated by an investment in the Fund
over a seven-day period. This income is then "annualized." 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 average yield because of the compounding effect of this assumed
reinvestment. See "Performance Information - Yield Computations" in the SAI.
<PAGE>
================================================================================
                        DIVIDENDS AND OTHER DISTRIBUTIONS

        Each Fund, except the Money Market Fund, intends to distribute to its
shareholders annually any net investment income, net realized capital gains, and
net realized gains from foreign currency transactions. The Money Market Fund
ordinarily will declare dividends from net investment income on a daily basis
and distribute those dividends monthly. All income dividends and distributions
of net capital gains and net gains from foreign currency transactions, if any,
of each Fund will be automatically reinvested in additional shares of the Fund
at the net asset value calculated on the ex-distribution date, unless you
request otherwise in writing. Dividends and other distributions of a Fund are
taxable to its shareholders, as discussed below under "Taxes," whether the
dividends or other distributions are reinvested in additional shares or are
received in cash. You will receive a statement of your account at least
quarterly.


================================================================================
                                      TAXES

        Each Fund is treated as a separate corporation for Federal income tax
purposes and will seek to qualify as a regulated investment company ("RIC")
under Subchapter M of the Internal Revenue Code of 1986, as amended ("Code").
Because of the investment strategies of each Fund other than the Money Market
Fund, there can be no assurance that any such Fund will qualify as a RIC. If a
Fund so qualifies and satisfies the distribution requirement under the Code for
a taxable year, the Fund will not be subject to Federal income tax on the part
of its investment company taxable income (generally consisting of net investment
income, net short-term capital gains, and net gains from certain foreign
currency transactions) and net capital gain (the excess of net long-term capital
gain over net short-term capital loss) it distributes to its shareholders for
that year. If a Fund fails to qualify as a RIC for any taxable year, its taxable
income, including net capital gain, will be taxed at corporate income tax rates
(up to 35%) and it will not receive a deduction for distributions to its
shareholders.
        To qualify as a RIC, a Fund must satisfy certain requirements, including
certain diversification requirements. The investment by a Fund, other than the
Money Market Fund, primarily in options and futures positions entails some risk
that such a Fund might fail to satisfy those diversification requirements
because of some uncertainty regarding the valuation of such positions. For
additional information concerning these requirements, see "Dividends, Other
Distributions and Taxes" in the SAI.
        If the Trust determines that a Fund will not qualify as a RIC and that
Federal income tax likely will be payable by the Fund for its current taxable
year, the Trust will make a good-faith estimate of the Fund's anticipated tax
liability, which will be accrued as tax expenses, and will establish procedures
for the Fund to reflect that liability in its net asset value per share.
Thereafter, the Trust will determine daily whether it is appropriate to continue
to accrue that tax expense and, if so, will make a good-faith estimate of the
amount thereof. Any amount by which any such accrual is reduced, or the entire
amount of the accrual if the Trust determines that accrual is no longer
appropriate, will be reclassified as a reduction of tax expenses.
<PAGE>
        Dividends from a Fund's investment company taxable income, if any, are
taxable to its shareholders as ordinary income (at rates up to 39.6% for
individuals), regardless of whether the dividends are reinvested in Fund shares
or received in cash. Distributions of a Fund's net capital gain, if any, when
designated as such, are taxable to its shareholders as long-term capital gains
(at rates of up to 28% for individuals), regardless of how long they have held
their Fund shares and whether the distributions are reinvested in Fund shares or
received in cash. The Taxpayer Relief Act of 1997 ("Act"), enacted in August
1997, dramatically changes the taxation of net capital gain, by applying
different rates (including reduced maximum rates of 20%, 18%, 10%, and 8%)
thereto depending on the taxpayer's holding period and marginal rate of Federal
income tax. The Act, however, does not address the application of these rules to
distributions by RICs and instead authorizes the issuance of regulations to do
so. Accordingly, shareholders should consult their tax advisers as to the effect
of the Act on distributions by a Fund to them of net capital gain. Shareholders
that are not subject to tax on their income generally will not be required to
pay tax on distributions. Statements as to the Federal tax status of each Fund's
distributions will be mailed to its shareholders annually. Shareholders should
consult their tax advisers concerning the tax status of a Fund's distributions
in their own states and localities.
        Shareholders are required by law to certify that their taxpayer
identification number ("TIN") is correct and that they are not subject to
back-up withholding. Each Fund is required to withhold 31% of all dividends,
capital gain distributions, and redemption proceeds payable to individuals and
certain other non-corporate shareholders who do not provide the Fund with a
correct TIN. Withholding at that rate also is required from dividends and
capital gain distributions payable to such shareholders who otherwise are
subject to back-up withholding.
        Because the foregoing only summarizes some of the important tax
considerations affecting the Funds and their shareholders, please see the
further discussion in the SAI. Prospective investors are urged to consult their
tax advisers.

                   MANAGEMENT AND ADMINISTRATION OF THE TRUST

BOARD OF TRUSTEES
        The business and affairs of each Fund are managed under the direction of
the Trustees. The Trustees are responsible for the general supervision of the
Funds' business affairs and for exercising all the Funds' powers except those
reserved to the shareholders. The day-to-day operations of the Funds are the
responsibility of the Trust's officers.

INVESTMENT ADVISER
        Rafferty Asset Management, LLC, 550 Mamaroneck Avenue, Harrison, New
York 10528, provides investment advice to the Funds. The Adviser is a newly
created investment adviser and has had no previous experience advising
investment companies. The Adviser was organized as a New York limited liability
corporation in May 1997. Lawrence C. Rafferty owns a controlling interest in the
Adviser.
        The Adviser manages the investment of the assets of each Fund, in
accordance with its investment objective, policies and limitations, subject to
the general supervision and control of the Trustees and the officers of the
Trust. The Adviser bears all costs associated with providing these advisory
services and the expenses of the Trustees who are affiliated persons of the
Adviser. The Adviser, from its own resources, also may make payments to
broker-dealers and other financial institutions for their expenses in connection
with the distribution of Fund shares, and otherwise currently pays all
distribution costs for Fund shares.
<PAGE>
        Under an investment agreement between the Trust and the Adviser, each
Fund pays the Adviser a fee at an annualized rate, based on a percentage of its
daily net assets: 0.75% for the Japan/Long Fund, the U.S. Plus Fund, and the OTC
Plus Fund; 0.90% for the Japan/Short Fund, the U.S./Short Fund, and the
OTC/Short Fund; and 0.50% for the Money Market Fund.

PORTFOLIO MANAGEMENT
        Each Fund, except for the OTC Plus Fund and the OTC/Short Fund, is 
managed by an investment committee, which is responsible for the investment
activities of the Funds. 
        James T. Apple is the portfolio manager for the OTC Plus Fund and the 
OTC/Short Fund. From 1992 to December 1993, he was Director of Investments
for The Rushmore Funds, Inc. From February 1994 to May 1997, Mr. Apple was
portfolio manager for the Rydex OTC, which seeks to match the performance of the
Nasdaq Index, and the U.S. Government Bond Funds.

ADMINISTRATOR
        The Trust has entered into an Administrative Services Agreement with
Firstar Trust Company ("Administrator") that obligates the Administrator to
provide the Funds with administrative and management services, other than
investment advisory services. As compensation for these services, the Trust pays
the Administrator a fee of .06% of the first $200,000,000 of the Trust's average
daily net assets, .05% of the next $300,000,000 of the Trust's average daily net
assets, and .03% of the Trust's average daily net assets in excess of
$500,000,000. Notwithstanding the foregoing, the Administrator's minimum annual
fee is $170,000.

DISTRIBUTOR
        First Data Distributors, Inc. ("Distributor"), 4400 Computer Drive,
Westboro, Massachusetts 01581, serves as the distributor of the Funds' shares.
The Distributor has entered into dealer agreements with participating dealers
who will distribute shares of the Funds.

TRANSFER AGENT AND CUSTODIAN
        Firstar Trust Company, 615 East Michigan Street, Milwaukee, Wisconsin
53202, serves as the transfer agent and custodian of the portfolio securities of
the Trust.

INDEPENDENT AUDITORS
        Price Waterhouse LLP, 100 East Wisconsin Avenue, Suite 1500, Milwaukee,
Wisconsin 53202, are the auditors of and the independent accountants for the
Trust.

================================================================================
                       GENERAL INFORMATION ABOUT THE TRUST

ORGANIZATION OF THE TRUST AND VOTING RIGHTS
        The Trust was organized as a Massachusetts business trust on June 6,
1997 and registered with the SEC as an open-end management investment company
under the 1940 Act. The Trust may issue unlimited shares of beneficial interest,
no par value, in such separate and distinct series and classes of shares as the
Trustees shall from time to time establish. The shares of beneficial interest of
the Trust presently are divided into seven separate series.
<PAGE>
        Fund shares have equal voting rights. Only shares of a particular Fund
may vote on matters affecting that Fund. All shares of the Trust vote on matters
affecting the Trust as a whole and to elect Trustees. Share voting rights are
not cumulative, and shares have no preemptive or conversion rights. Shares of
the Trust are nontransferable.
        As a Massachusetts business trust, the Trust is not obligated to conduct
annual shareholder meetings. However, the Trust will hold special shareholder
meetings whenever required to do so under the Federal securities laws or the
Trust's Declaration of Trust or its By-Laws. Shareholders may remove Trustees
from office by votes cast at a special meeting of shareholders. If requested by
the shareholders of at least 10% of the outstanding shares of the Trust, the
Trustees will call a special meeting of shareholders to vote on the removal of a
Trustee and will assist in communications with other shareholders.

FUND EXPENSES
        Expenses of the Trust that are not directly attributable to a Fund are
typically allocated among the Funds in proportion to their respective net
assets, number of shareholder accounts, or net sales, where applicable. Each
Fund pays all of its own expenses. These expenses include organizational costs,
expenses for legal accounting and auditing services, preparing (including
typesetting and printing) reports, prospectuses, supplements thereto and notices
to its existing shareholders, advisory and management fees, fees and expenses of
the custodian and transfer and dividend disbursing agents, the distribution fee,
the expense of issuing and redeeming shares, the cost of registering shares
under the Federal and state laws, shareholder meeting and related proxy
solicitation expenses, the fees and out-of-pocket expenses of Trustees who are
not affiliated with the Adviser, insurance, brokerage costs, litigation, and
other expenses properly payable by the Funds.

CLASSIFICATION OF THE FUNDS
        Each Fund (other than the Money Market Fund) is a "non-diversified"
series of the Trust pursuant to the 1940 Act. A Fund is considered
"non-diversified" because a relatively high percentage of its assets may be
invested in the securities of a limited number of issuers, primarily within the
same industry or economic sector. A non-diversified Fund's portfolio securities,
therefore, may be more susceptible to any single economic, political, or
regulatory occurrence than the portfolio securities of a diversified investment
company.
        A Fund's classification as a "non-diversified" investment company means
that the proportion of its assets that may be invested in the securities of a
single issuer is not limited by the 1940 Act. Each Fund, however, intends to
qualify as a RIC. This requires, among other things, that each Fund, at the end
of each quarter of its tax year, meet certain diversification standards.

CONCENTRATION OF INVESTMENTS
        The OTC Plus Fund and the OTC/Short Fund generally do not intend to
concentrate more than 25% of their respective investments in a particular
industry. However, because these Funds seek investment results that correspond
to 125% and the inverse, respectively, of the performance of the Nasdaq Index,
the Funds may invest more than 25% of their assets in securities of issuers in
one industry. When a Fund concentrates its investments in an industry,
financial, economic, business and other developments affecting issuers in that
industry will have a greater effect on the Fund than if the Fund had not
concentrated its assets in that industry. Accordingly, the performance of these
Funds may be subject to a greater risk of market fluctuation than that of a fund
invested in a wider spectrum of industries.
<PAGE>
DISTRIBUTION OF FUND SHARES
        The Funds have adopted a distribution plan (the "Plan") pursuant to Rule
12b-1 under the 1940 Act. The Plan provides that each Fund will compensate the
Distributor for certain expenses incurred in the distribution of that Fund's
shares and the servicing and maintenance of existing Fund shareholder accounts.
However, the Trustees have not authorized payment of any fees pursuant to
the Plan.

MASTER/FEEDER OPTION
        The Trust may in the future seek to achieve a Fund's investment
objective by investing all net assets of that Fund ("Feeder Fund") in another
investment company ("Master Fund") having the same investment objective and
substantially the same investment policies and restrictions as those applicable
to the Feeder Fund. It is expected that any such investment company would be
managed by the Adviser in substantially the same manner as the Feeder Fund. If
permitted by applicable laws and policies then in effect, any such investment
may be made in the sole discretion of the Trustees without further approval of
shareholders of the Funds. However, the Funds' shareholders will be given 30
days' prior notice of any such investment. Such investment would be made only if
the Trustees determine it to be in the best interests of the Funds and their
shareholders. In making that determination, the Trustees will consider, among
other things, the benefits to shareholders and/or the opportunity to reduce
costs and achieve operational efficiencies. No assurance can be given that costs
will be materially reduced if this option is implemented.

SHAREHOLDER INQUIRIES
        Shareholder inquiries can be made by telephone to the Trust at (800)
851-0511.

The Potomac Funds (the "Trust") is a no-load management  investment  company, or
mutual  fund,  which  consists  of seven  separate  investment  portfolios  (the
"Funds").  The Funds are designed  principally  for  experienced  investors  who
intend to follow a global asset allocation strategy.  The Funds are not designed
for inexperienced or less sophisticated  investors.  An important feature of the
Trust is that it primarily  consists of pairs of Funds, one of which attempts to
provide  results  correlating to a specific  index,  while the other attempts to
provide  inverse  performance,  that  is,  similar  to a short  position  in the
specific index. In particular,  the following Funds seek investment results that
correspond over time to the following benchmarks:

FUND                          BENCHMARK
Potomac Japan/Long Fund       Nikkei 225 Stock Average
Potomac Japan/Short Fund      Inverse (opposite) of the Nikkei 225 Stock Average
Potomac U.S. Plus  Fund       150% of the performance of the Standard & Poor's 
                              500 Composite Stock Price Index[TRADEMARK]
Potomac U.S./Short  Fund      Inverse  (opposite)  of the 
                              Standard & Poor's 500 Composite Stock Price 
                              Index[TRADEMARK]
Potomac OTC Plus Fund         125% of the  performance  of the Nasdaq 100 Stock
                              Index[TRADEMARK]
Potomac OTC/Short Fund        Inverse (opposite) of the Nasdaq 100 Stock 
                              Index[TRADEMARK]

The Trust also offers the Potomac U.S. Government Money Market Fund, which seeks
security of principal,  current  income and liquidity by investing  primarily in
money market instruments issued or guaranteed,  as to principal and interest, by
the U.S.  Government,  its  agencies  or  instrumentalities.  THE FUND  SEEKS TO
MAINTAIN A CONSTANT  $1.00 NET ASSET  VALUE PER SHARE,  ALTHOUGH  THIS CANNOT BE
ASSURED.  SHARES OF THIS FUND ARE NOT DEPOSITS OR OBLIGATIONS,  OR GUARANTEED OR
ENDORSED BY, THE FEDERAL  DEPOSIT  INSURANCE  CORPORATION,  THE FEDERAL  RESERVE
BOARD OR ANY OTHER AGENCY.  AN  INVESTMENT  IN THIS FUND IS NEITHER  INSURED NOR
GUARANTEED BY THE UNITED STATES GOVERNMENT.

This Statement of Additional Information is not a prospectus.  It should be read
in conjunction with the Trust's  Prospectus dated October 1, 1997. A copy of the
Prospectus  is  available,  without  charge,  upon  request  to the Trust at the

                                THE POTOMAC FUNDS

The Trust is a  Massachusetts  business  trust  organized on June 6, 1997 and is
registered  with the Securities and Exchange  Commission  ("SEC") as an open-end
management  investment  company  under the  Investment  Company Act of 1940,  as
amended ("1940 Act"). The Trust currently consists of seven separate series: the
Potomac  Japan/Long  Fund  ("Japan/Long  Fund"),  the Potomac  Japan/Short  Fund
("Japan/Short Fund"), the Potomac U.S. Plus Fund ("U.S. Plus Fund"), the Potomac
U.S./Short  Fund  ("U.S.  Short  Fund"),  the  Potomac  OTC Plus Fund ("OTC Plus
Fund"),  the Potomac  OTC/Short  Fund  ("OTC/Short  Fund") and the Potomac  U.S.
Government Money Market Fund ("Money Market Fund") (collectively,  the "Funds").
The Trust may offer additional series in the future.

The Funds are designed  principally for experienced  investors  seeking a global
asset  allocation  vehicle.  Except for the Money Market Fund, the Funds provide
investment  exposure to various securities  markets.  Each Fund seeks investment
results that correspond over time to a specific benchmark.  The terms "long" and
"short" in the Funds'  names are not  intended  to refer to the  duration of the
Funds'  investment  portfolios.  The  Funds  may  be  used  independently  or in
combination with each other as part of an overall strategy.


                       INVESTMENT POLICIES AND TECHNIQUES

GENERAL
- -------
The following  information  supplements  the discussion in the Prospectus of the
investment objective, policies and limitations of each Fund. Please refer to the
sections   entitled   "Investment   Objectives  and  Policies"  and  "Investment
Techniques and Other Investment  Policies" in the Prospectus for a discussion of
the investment  objectives and policies of the Funds. Rafferty Asset Management,
LLC (the "Adviser") serves as each Fund's investment adviser.  Capitalized terms
not  otherwise  defined  herein  shall have the same  meaning as assigned in the
Prospectus.

The Funds may engage in the investment  strategies  discussed below. There is no
assurance  that any of these  strategies or any other  strategies and methods of
investment  available  to a Fund will  result in the  achievement  of the Fund's
objectives.

OPTIONS, FUTURES AND OTHER STRATEGIES
- -------------------------------------
GENERAL. As discussed in the Prospectus,  each Fund (other than the Money Market
Fund) may use  certain  options,  futures  contracts  (sometimes  referred to as
"futures"),  options on futures contracts,  forward currency  contracts,  swaps,
caps, floors and collars (collectively, "Financial Instruments") as a substitute
for a comparable  market  position in the  underlying  security or currency,  to
attempt  to hedge or limit  the  exposure  of a  Fund's  position,  to  create a
synthetic money market position,  for certain tax-related purposes and to effect
closing transactions.  Each of the Japan/Long Fund and the Japan/Short Fund also
may  purchase  and sell  Financial  Instruments  on  Japanese  Yen to attempt to
eliminate the effect that fluctuations in the U.S.  Dollar/Japanese Yen exchange
rate may have on each Fund's net asset value per share.

The use of Financial  Instruments  is subject to applicable  regulations  of the
SEC, the several  exchanges upon which they are traded and the Commodity Futures


                                       3
<PAGE>



Trading Commission (the "CFTC"). In addition,  a Fund's ability to use Financial
Instruments  will  be  limited  by tax  considerations.  See  "Dividends,  Other
Distributions and Taxes."

In addition to the instruments,  strategies and risks described below and in the
Prospectus, the Adviser may discover additional opportunities in connection with
Financial  Instruments  and  other  similar  or  related  techniques.  These new
opportunities  may become available as the Adviser  develops new techniques,  as
regulatory  authorities  broaden the range of permitted  transactions and as new
Financial Instruments or other techniques are developed. The Adviser may utilize
these  opportunities  to the  extent  that  they  are  consistent  with a Fund's
investment  objective  and  permitted  by a Fund's  investment  limitations  and
applicable  regulatory  authorities.  The  Funds'  Prospectus  or  SAI  will  be
supplemented  to the extent that new products or techniques  involve  materially
different risks than those described below or in the Prospectus.

SPECIAL RISKS. The use of Financial Instruments involves special  considerations
and risks,  certain of which are described below. Risks pertaining to particular
Financial Instruments are described in the sections that follow.

(1)   Successful  use of most Financial  Instruments  depends upon the Adviser's
ability to predict  movements of the overall  securities  and currency  markets,
which  requires  different  skills  than  predicting  changes  in the  prices of
individual  securities.  There can be no assurance that any particular  strategy
will succeed.

(2)   Options and futures prices can diverge from the prices of their underlying
instruments.  Options and futures prices are affected by such factors as current
and  anticipated  short-term  interest  rates,  changes  in  volatility  of  the
underlying  instrument and the time remaining until  expiration of the contract,
which may not affect security prices the same way.  Imperfect  correlation  also
may result from  differing  levels of demand in the options and futures  markets
and the  securities  markets,  from  structural  differences  in how options and
futures  and  securities  are  traded,   and  from  imposition  of  daily  price
fluctuation limits or trading halts.

(3)   As  described  below,  a Fund  might be  required  to  maintain  assets as
"cover,"  maintain  segregated  accounts or make margin  payments  when it takes
positions in Financial Instruments involving obligations to third parties (E.G.,
Financial  Instruments other than purchased  options).  If a Fund were unable to
close out its positions in such Financial  Instruments,  it might be required to
continue to maintain  such  assets or accounts or make such  payments  until the
position expired or matured. These requirements might impair a Fund's ability to
sell a  portfolio  security  or  make an  investment  at a time  when  it  would
otherwise  be  favorable  to do so,  or  require  that a Fund  sell a  portfolio
security at a disadvantageous  time. A Fund's ability to close out a position in
a Financial  Instrument prior to expiration or maturity depends on the existence
of a liquid  secondary  market or, in the absence of such a market,  the ability
and willingness of the other party to the transaction  (the  "counterparty")  to
enter  into a  transaction  closing  out the  position.  Therefore,  there is no
assurance  that any  position  can be  closed  out at a time and  price  that is
favorable to a Fund.

COVER.  Transactions using Financial Instruments,  other than purchased options,
expose a Fund to an obligation to another  party. A Fund will not enter into any
such transactions unless it owns either (1) an offsetting  ("covered")  position
in  securities,  currencies  or other  options,  futures  contracts  or  forward


                                       4
<PAGE>



currency contracts, or (2) cash and liquid assets with a value, marked-to-market
daily,  sufficient to cover its potential  obligations to the extent not covered
as provided in (1) above.  Each Fund will comply with SEC  guidelines  regarding
cover for these  instruments  and will, if the guidelines so require,  set aside
cash or liquid  assets in an account with its  custodian,  Firstar Trust Company
("Custodian"), in the prescribed amount as determined daily.

Assets used as cover or held in an account  cannot be sold while the position in
the  corresponding  Financial  Instrument is open, unless they are replaced with
other appropriate  assets.  As a result,  the commitment of a large portion of a
Fund's  assets to cover or accounts  could impede  portfolio  management  or the
Fund's ability to meet redemption requests or other current obligations.

OPTIONS.  The value of an option position will reflect,  among other things, the
current market value of the  underlying  investment,  the time  remaining  until
expiration,  the  relationship  of the exercise price to the market price of the
underlying  investment  and  general  market  conditions.  Options  that  expire
unexercised have no value.

A Fund may  effectively  terminate  its right or  obligation  under an option by
entering  into a closing  transaction.  For example,  a Fund may  terminate  its
obligation  under a call or put  option  that it had  written by  purchasing  an
identical call or put option;  this is known as a closing purchase  transaction.
Conversely,  a Fund may  terminate  a  position  in a put or call  option it had
purchased by writing an identical put or call option; this is known as a closing
sale transaction. Closing transactions permit a Fund to realize profits or limit
losses on an option position prior to its exercise or expiration.

RISKS OF OPTIONS ON SECURITIES. Exchange-traded options in the United States are
issued by a clearing  organization  affiliated  with the  exchange  on which the
option is listed that, in effect, guarantees completion of every exchange-traded
option transaction. In contrast,  over-the-counter ("OTC") options are contracts
between a Fund and its counterparty (usually a securities dealer or a bank) with
no clearing organization  guarantee.  Thus, when a Fund purchases an OTC option,
it relies on the counterparty  from whom it purchased the option to make or take
delivery of the underlying  investment  upon exercise of the option.  Failure by
the  counterparty  to do so would  result in the loss of any premium paid by the
Fund as well as the loss of any expected benefit of the transaction.

A Fund's ability to establish and close out positions in exchange-traded options
depends on the existence of a liquid market.  However, there can be no assurance
that such a market will exist at any particular time.  Closing  transactions can
be made for OTC options only by negotiating  directly with the counterparty,  or
by a transaction in the secondary market if any such market exists. There can be
no  assurance  that a Fund will in fact be  liable  to close  out an OTC  option
position at a favorable price prior to expiration. In the event of insolvency of
the counterparty,  a Fund might be unable to close out an OTC option position at
any time prior to its expiration.

If a Fund  were  unable to  effect a  closing  transaction  for an option it had
purchased,  it would have to  exercise  the option to realize  any  profit.  The
inability to enter into a closing purchase transaction for a covered call option
written by a Fund could cause  material  losses because the Fund would be unable
to sell the  investment  used as cover for the written  option  until the option
expires or is exercised.

OPTIONS ON  INDICES.  Puts and calls on indices are similar to puts and calls on
securities or futures contracts except that all settlements are in cash and gain
or loss  depends  on  changes  in the  index in  question  rather  than on price
movements in individual  securities or futures  contracts.  When a Fund writes a
call on an index, it receives a premium and agrees that, prior to the expiration
date,  the purchaser of the call,  upon exercise of the call,  will receive from
the Fund an amount of cash if the closing level of the index upon which the call
is based is greater than the exercise  price of the call.  The amount of cash is
equal to the difference  between the closing price of the index and the exercise
price of the call times a specified  multiple  ("multiplier"),  which determines
the total value for each point of such difference. When a Fund buys a call on an
index,  it pays a premium and has the same rights to such call as are  indicated
above.  When a Fund buys a put on an index, it pays a premium and has the right,
prior to the expiration  date, to require the seller of the put, upon the Fund's
exercise  of the put,  to deliver  to the Fund an amount of cash if the  closing
level of the index upon which the put is based is less than the  exercise  price
of the put, which amount of cash is determined by the  multiplier,  as described
above for calls. When a Fund writes a put on an index, it receives a premium and
the purchaser of the put has the right, prior to the expiration date, to require
the Fund to deliver to it an amount of cash equal to the difference  between the
closing  level of the index and the exercise  price times the  multiplier if the
closing level is less than the exercise price.

RISKS OF  OPTIONS  ON  INDICES.  If a Fund has  purchased  an index  option  and
exercises it before the closing index value for that day is  available,  it runs
the risk that the level of the underlying index may subsequently change. If such
a change causes the exercised option to fall out-of-the-money,  the Fund will be
required to pay the difference  between the closing index value and the exercise
price of the option (times the applicable multiplier) to the assigned writer.

OTC OPTIONS. Unlike exchange-traded options, which are standardized with respect
to the underlying  instrument,  expiration date, contract size and strike price,
the terms of OTC  options  (options  not  traded  on  exchanges)  generally  are
established  through  negotiation  with the other party to the option  contract.
While this type of  arrangement  allows a Fund great  flexibility  to tailor the
option  to  its  needs,  OTC  options   generally   involve  greater  risk  than
exchange-traded  options,  which are guaranteed by the clearing  organization of
the exchanges where they are traded.

Generally,  OTC foreign  currency  options used by the  Japan/Long  Fund and the
Japan/Short  Fund are  European-style  options.  This  means  that the option is
exercisable  only  immediately  prior to its expiration.  This is in contrast to
American-style  options,  which  are  exercisable  at  any  time  prior  to  the
expiration date of the option.

FUTURES  CONTRACTS  AND  OPTIONS  ON  FUTURES  CONTRACTS.  No price is paid upon
entering  into a  futures  contract.  Instead,  at the  inception  of a  futures
contract a Fund is required to deposit  "initial  margin" in an amount generally
equal to 10% or less of the contract  value.  Margin also must be deposited when
writing  a call  or  put  option  on a  futures  contract,  in  accordance  with
applicable  exchange rules.  Unlike margin in securities  transactions,  initial
margin  does not  represent  a  borrowing,  but  rather  is in the  nature  of a
performance  bond or  good-faith  deposit  that is  returned  to the Fund at the
termination  of  the  transaction  if  all  contractual  obligations  have  been
satisfied. Under certain circumstances,  such as periods of high volatility, the


                                       6
<PAGE>


Fund may be required by an exchange to increase the level of its initial  margin
payment,  and initial margin  requirements  might be increased  generally in the
future by regulatory action.

Subsequent  "variation  margin"  payments  are  made  to and  from  the  futures
commission merchant daily as the value of the futures position varies, a process
known as "marking-to-market."  Variation margin does not involve borrowing,  but
rather  represents a daily  settlement  of the Fund's  obligations  to or from a
futures  commission  merchant.  When a Fund  purchases  an  option  on a futures
contract,  the premium paid plus  transaction  costs is all that is at risk.  In
contrast,  when a Fund purchases or sells a futures contract or writes a call or
put option thereon,  it is subject to daily variation margin calls that could be
substantial  in  the  event  of  adverse  price  movements.   If  the  Fund  has
insufficient cash to meet daily variation margin requirements,  it might need to
sell securities at a time when such sales are disadvantageous.

Purchasers  and  sellers of futures  contracts  and options on futures can enter
into  offsetting  closing  transactions,  similar  to  closing  transactions  in
options, by selling or purchasing,  respectively, an instrument identical to the
instrument  purchased  or sold.  Positions  in  futures  and  options on futures
contracts  may be closed only on an  exchange or board of trade that  provides a
secondary  market.  However,  there can be no assurance that a liquid  secondary
market will exist for a particular contract at a particular time. In such event,
it may not be possible to close a futures contract or options position.

Under certain circumstances, futures exchanges may establish daily limits on the
amount that the price of a futures  contract or an option on a futures  contract
can vary from the previous day's settlement  price;  once that limit is reached,
no trades may be made that day at a price  beyond the limit.  Daily price limits
do not limit  potential  losses because prices could move to the daily limit for
several  consecutive  days  with  little  or  no  trading,   thereby  preventing
liquidation of unfavorable positions.

If a Fund were unable to liquidate a futures  contract or an option on a futures
position due to the absence of a liquid  secondary  market or the  imposition of
price limits, it could incur substantial  losses.  The Fund would continue to be
subject to market risk with respect to the position. In addition,  except in the
case of purchased options,  the Fund would continue to be required to make daily
variation  margin  payments  and might be required  to  maintain  cash or liquid
assets in an account.

RISKS OF FUTURES  CONTRACTS AND OPTIONS  THEREON.  The ordinary  spreads between
prices  in the cash and  futures  markets  (including  the  options  on  futures
markets), due to differences in the natures of those markets, are subject to the
following factors, which may create distortions.  First, all participants in the
futures  market are  subject to margin  deposit  and  maintenance  requirements.
Rather than meeting additional margin deposit requirements,  investors may close
futures  contracts  through  offsetting  transactions,  which could  distort the
normal relationships between the cash and futures markets. Second, the liquidity
of  the  futures  market  depends  on  participants   entering  into  offsetting
transactions  rather than making or taking delivery.  To the extent participants
decide  to make or take  delivery,  liquidity  in the  futures  market  could be
reduced,  thus  producing   distortion.   Third,  from  the  point  of  view  of
speculators,  the deposit  requirements  in the futures  market are less onerous
than  margin  requirements  in  the  securities  market.  Therefore,   increased
participation  by speculators in the futures  market may cause  temporary  price
distortions.

FOREIGN CURRENCY  STRATEGIES - SPECIAL  CONSIDERATIONS.  The Japan/Long Fund and
the Japan/Short  Fund may use options and futures  contracts on Japanese Yen, as
described  above,  and forward  contracts,  swaps,  caps,  floors and collars on
Japanese Yen, as described below.

The value of Financial Instruments on foreign currencies depends on the value of
the underlying  currency  relative to the U.S. Dollar.  Because foreign currency
transactions  occurring  in the  interbank  market might  involve  substantially
larger amounts than those involved in the use of such Financial  Instruments,  a
Fund could be disadvantaged  by having to deal in the odd-lot market  (generally
consisting of transactions  of less than $1 million) for the underlying  foreign
currencies at prices that are less favorable than for round lots.

There is no systematic reporting of last sale information for foreign currencies
or any regulatory requirement that quotations available through dealers or other
market  sources  be firm or  revised on a timely  basis.  Quotation  information
generally is representative  of very large  transactions in the interbank market
and thus  might not  reflect  odd-lot  transactions  where  rates  might be less
favorable.   The   interbank   market  in  foreign   currencies   is  a  global,
round-the-clock  market.  To the extent the U.S.  options or futures markets are
closed while the markets for the underlying currencies remain open,  significant
price and rate movements might take place in the underlying  markets that cannot
be reflected in the markets for the Financial Instruments until they reopen.

Settlement of transactions  involving  foreign  currencies  might be required to
take place  within the country  issuing the  underlying  currency.  Thus, a Fund
might be required to accept or make delivery of the underlying  foreign currency
in accordance with any U.S. or foreign regulations  regarding the maintenance of
foreign banking  arrangements by U.S. residents and might be required to pay any
fees,  taxes and charges  associated with such delivery  assessed in the issuing
country.

FORWARD  CURRENCY  CONTRACTS.  The Japan/Long Fund and the Japan/Short  Fund may
enter into forward  currency  contracts  to purchase or sell  Japanese Yen for a
fixed amount of U.S. Dollars. A forward currency contract involves an obligation
to purchase or sell a specific currency at a future date, which may be any fixed
number of days (term) from the date of the forward currency contract agreed upon
by the  parties,  at a price set at the time of the forward  currency  contract.
These forward  currency  contracts are traded directly  between currency traders
(usually large commercial banks) and their customers.

The cost to a Fund of engaging in forward currency contracts varies with factors
such as the currency involved,  the length of the contract period and the market
conditions  then  prevailing.  Because  forward  currency  contracts are usually
entered into on a principal  basis, no fees or commissions are involved.  When a
Fund enters into a forward currency  contract,  it relies on the counterparty to
make  or  take  delivery  of the  underlying  currency  at the  maturity  of the
contract.  Failure by the  counterparty to do so would result in the loss of any
expected benefit of the transaction.

As is the case  with  futures  contracts,  purchasers  and  sellers  of  forward
currency  contracts can enter into offsetting closing  transactions,  similar to
closing   transactions   on  futures   contracts,   by  selling  or  purchasing,
respectively,  an  instrument  identical  to the  instrument  purchased or sold.
Secondary  markets generally do not exist for forward currency  contracts,  with
the result that closing transactions  generally can be made for forward currency


                                       8
<PAGE>



contracts only by negotiating directly with the counterparty. Thus, there can be
no  assurance  that a Fund will in fact be able to close out a forward  currency
contract at a favorable  price prior to maturity.  In addition,  in the event of
insolvency  of the  counterparty,  a Fund might be unable to close out a forward
currency contract at any time prior to maturity. In either event, the Fund would
continue to be subject to market risk with  respect to the  position,  and would
continue to be required to maintain a position in securities  denominated in the
foreign currency or to maintain cash or liquid assets in a segregated account.

The precise matching of forward  currency  contract amounts and the value of the
securities  involved  generally  will not be possible  because the value of such
securities,  measured in the  foreign  currency,  will change  after the forward
currency contract has been  established.  Thus, a Fund might need to purchase or
sell  foreign  currencies  in the spot (cash)  market to the extent such foreign
currencies are not covered by forward currency contracts.

COMBINED  POSITIONS.  A Fund may purchase and write options in combination  with
each other, or in combination  with futures or forward currency  contracts.  For
example,  a Fund may  purchase a put option and write a call  option on the same
underlying instrument,  in order to construct a combined position whose risk and
return  characteristics  are  similar  to  selling a futures  contract.  Another
possible  combined  position  would involve  writing a call option at one strike
price and buying a call option at a lower price,  in order to reduce the risk of
the written call option in the event of a substantial  price  increase.  Because
combined  options  positions  involve  multiple  trades,  they  result in higher
transaction costs and may be more difficult to open and close out.

SWAPS,  CAPS,  FLOORS AND COLLARS.  Swap agreements,  including caps, floors and
collars,  can be individually  negotiated and  structured.  Swap agreements will
tend to shift a Fund's  investment  exposure  from  one  type of  investment  to
another.  For example, if a Fund agrees to exchange payments based on a floating
rate of  interest  for  payments  based on a  specified  stock  index,  the swap
agreement would tend to decrease the Fund's exposure to U.S.  interest rates and
increase its exposure to changes in the value of the index. Caps and floors have
an effect similar to buying or writing options.

The  creditworthiness of firms with which a Fund enters into swaps, caps, floors
or collars  will be  monitored  by the  Adviser in  accordance  with  procedures
adopted by the  Trust's  Board of Trustees  ("Trustees"  or the  "Board").  If a
default  occurs  by the  other  party  to such  transaction,  a Fund  will  have
contractual remedies pursuant to the agreements related to the transaction.

The net  amount  of the  excess,  if  any,  of a  Fund's  obligations  over  its
entitlements  with  respect  to each swap  entered  into on a net basis  will be
accrued  on a daily  basis  and an amount  of cash or  liquid  assets  having an
aggregate  net  asset  value  at  least  equal  to the  accrued  excess  will be
maintained in an account with the Custodian that satisfies the  requirements  of
the 1940 Act.  Each Fund also will  establish  and  maintain  such  account with
respect to its total  obligations under any swaps that are not entered into on a
net basis and with  respect to any caps or floors  that are written by the Fund.
The Adviser and the Funds believe that such obligations do not constitute senior
securities  under the 1940 Act and,  accordingly,  will not treat  them as being
subject to a Fund's borrowing restrictions.

U.S. GOVERNMENT SECURITIES
- --------------------------
Securities  issued or  guaranteed  by the U.S.  Government  or its  agencies  or
instrumentalities  ("U.S.  Government Securities") include Treasury Bills (which
mature within one year of the date they are issued),  Treasury Notes (which have
maturities  of one to ten  years)  and  Treasury  Bonds  (which  generally  have
maturities of more than 10 years).  All such Treasury  securities  are backed by
the full faith and credit of the United States.

U.S.  Government  agencies  and   instrumentalities   that  issue  or  guarantee
securities include, but are not limited to, the Federal Housing  Administration,
Fannie Mae (formerly,  the Federal National Mortgage  Association),  the Farmers
Home  Administration,  the  Export-Import  Bank of the United States,  the Small
Business  Administration,  the Government National Mortgage Association ("Ginnie
Mae"), the General Services  Administration,  the Central Bank for Cooperatives,
the  Federal  Home  Loan  Banks,  the  Federal  Home Loan  Mortgage  Corporation
("Freddie  Mac"),  the Farm  Credit  Banks,  the  Maritime  Administration,  the
Tennessee Valley Authority,  the Resolution Funding  Corporation and the Student
Loan Marketing Association.

Securities   issued   or   guaranteed   by   U.S.    Government   agencies   and
instrumentalities  are not always  supported by the full faith and credit of the
United States.  Some, such as securities  issued by the Federal Home Loan Banks,
are  backed by the right of the  agency or  instrumentality  to borrow  from the
Treasury. Others, such as securities issued by Fannie Mae, are supported only by
the  credit of the  instrumentality  and by a pool of  mortgage  assets.  If the
securities are not backed by the full faith and credit of the United States, the
owner  of the  securities  must  look  principally  to the  agency  issuing  the
obligation  for  repayment  and may not be able to  assert a claim  against  the
United States in the event that the agency or instrumentality  does not meet its
commitment.  The Money  Market Fund will invest in  securities  of agencies  and
instrumentalities only if the Adviser is satisfied that the credit risk involved
is acceptable.

INDEXED SECURITIES
- ------------------
Each Fund (other than the Money Market Fund) may purchase  securities  the value
of which  varies  in  relation  to the  value of  other  securities,  securities
indices,   currencies  or  other  financial  indicators,   consistent  with  its
investment  objective.  Indexed securities  typically,  but not always, are debt
securities  or deposits  whose value at maturity or coupon rate is determined by
reference to a specific  instrument  or statistic.  Currency-indexed  securities
typically are short-term to  intermediate-term  debt  securities  whose maturity
values or interest  rates are  determined by reference to the values of one more
specified   foreign   currencies,   and  may  offer  higher   yields  than  U.S.
Dollar-denominated securities of equivalent issuers. Currency-indexed securities
may be positively  or  negatively  indexed;  that is, their  maturity  value may
increase when the value of a specified foreign currency increases,  resulting in
a security that performs similarly to a foreign-denominated instrument, or their
maturity  value may  decline  when the  value of a  specified  foreign  currency
increases,  resulting in a security whose price characteristics are similar to a
put on the underlying currency.

Recent  issuers of indexed  securities  have included  banks,  corporations  and
certain U.S. Government agencies. Certain indexed securities that are not traded
on an established market may be deemed illiquid.  See "Illiquid  Investments and
Restricted Securities" below.


                                       10
<PAGE>



AMERICAN DEPOSITORY RECEIPTS ("ADRS")
- ------------------------------------
ADRs include ordinary shares and New York shares.  ADRs may be purchased through
"sponsored" or  "unsponsored"  facilities.  A sponsored  facility is established
jointly by the issuer of the  underlying  security and a  depository,  whereas a
depository may establish an unsponsored  facility  without  participation by the
issuer of the depository  security.  Holders of unsponsored  depository receipts
generally  bear  all the  costs  of such  facilities  and the  depository  of an
unsponsored facility frequently is under no obligation to distribute shareholder
communications  received  from the issuer of the  deposited  security or to pass
through  voting  rights  to the  holders  of  such  receipts  of  the  deposited
securities.  ADRs are not  necessarily  denominated  in the same currency as the
underlying  securities  to  which  they  may be  connected.  Generally,  ADRs in
registered form are designed for use in the U.S.  securities  market and ADRs in
bearer form are designed for used outside the United States.

REPURCHASE AGREEMENTS
- ---------------------
Each Fund may enter into  repurchase  agreements  with banks that are members of
the Federal  Reserve System or securities  dealers who are members of a national
securities  exchange  or are  primary  dealers  in U.S.  Government  Securities.
Repurchase  agreements  generally  are for a short period of time,  usually less
than a week.  Repurchase  agreements with a maturity of more than seven days are
considered to be illiquid investments.  No Fund may enter into such a repurchase
agreement  if, as a result,  more than 15% (10% in the case of the Money  Market
Fund) of the value of its net assets  would then be invested in such  repurchase
agreements  and  other  illiquid  investments.  See  "Illiquid  Investments  and
Restricted Securities" below.

Each Fund follows  certain  procedures  and  guidelines  adopted by the Trustees
designed to minimize the risks inherent in such  transactions.  These procedures
include effecting repurchase transactions only with large,  well-capitalized and
well-established institutions whose financial condition will be monitored by the
Adviser. In addition,  each Fund will always receive, as collateral,  securities
whose market value,  including accrued  interest,  at all times will be at least
equal to 100% of the  dollar  amount  invested  by the  Fund in each  repurchase
agreement. If the seller defaults, a Fund might incur a loss if the value of the
collateral   securing  the  repurchase   agreement   declines  and  might  incur
disposition costs in connection with liquidating the collateral. In addition, if
bankruptcy or similar  proceedings  are commenced  with respect to the seller of
the  security,  realization  upon the  collateral  by a Fund may be  delayed  or
limited.

BORROWING
- ---------
The U.S.  Plus  Fund  and the OTC Plus  Fund may  borrow  money  for  investment
purposes. Each Fund may borrow money as a temporary measure for extraordinary or
emergency purposes and to meet redemption  requests without  immediately selling
portfolio securities.

U.S.  PLUS  FUND  AND OTC  PLUS  FUND.  Borrowing  for  investment  is  known as
leveraging.  Leveraging  investments,  by  purchasing  securities  with borrowed
money,  is  a  speculative   technique  that  increases  investment  risk  while
increasing investment  opportunity.  Leverage may exaggerate changes in a Fund's
net asset value.  Although the  principal of such  borrowings  will be fixed,  a
Fund's assets may change in value during the time the borrowing is  outstanding.
Leverage  also creates  interest  expenses for a Fund.  To the extent the income
derived from  securities  purchased  with borrowed  funds exceeds the interest a
Fund will have to pay,  that Fund's net income will be greater  than it would be
if leverage were not used.  Conversely,  if the income from the assets  obtained

                                       11
<PAGE>



with borrowed funds is not  sufficient to cover the cost of leveraging,  the net
income of a Fund will be less than it would be if  leverage  were not used,  and
therefore the amount  available for  distribution  to  shareholders as dividends
will be reduced.

ALL FUNDS.  Each Fund may borrow money to  facilitate  management  of the Fund's
portfolio by enabling the Fund to meet redemption  requests when the liquidation
of  portfolio  instruments  would  be  inconvenient  or  disadvantageous.   Such
borrowing is not for  investment  purposes  and will be repaid by the  borrowing
Fund promptly.

As  required by the 1940 Act, a Fund must  maintain  continuous  asset  coverage
(total assets,  including assets acquired with borrowed funds,  less liabilities
exclusive of  borrowings)  of 300% of all amounts  borrowed.  If at any time the
value of the required asset coverage declines as a result of market fluctuations
or  other  reasons,  a Fund  may be  required  to  sell  some  of its  portfolio
investments within three days to reduce the amount of its borrowings and restore
the  300%  asset  coverage,  even  though  it may  be  disadvantageous  from  an
investment standpoint to sell portfolio instruments at that time.

In  addition  to the  foregoing,  each Fund may  borrow  money  from a bank as a
temporary  measure for  extraordinary  or  emergency  purposes in amounts not in
excess of 5% of the value of its total assets.  This borrowing is not subject to
the foregoing 300% asset coverage  requirement.  Each Fund may pledge  portfolio
securities as the Adviser deems appropriate in connection with any borrowings.

LENDING PORTFOLIO SECURITIES
- ----------------------------
Each Fund may lend portfolio  securities with a value not exceeding 33 1/3% (10%
in the case of the Money Market  Fund) of its total assets to brokers,  dealers,
and financial institutions.  Borrowers are required continuously to secure their
obligations  to  return  securities  on  loan  from a  Fund  by  depositing  any
combination of short-term  government securities and cash as collateral with the
Fund. The  collateral  must be equal to at least 100% of the market value of the
loaned  securities,  which  will be  marked  to  market  daily.  While a  Fund's
portfolio  securities are on loan, the Fund continues to receive interest on the
securities loaned and simultaneously  earns either interest on the investment of
the collateral or fee income if the loan is otherwise  collateralized.  The Fund
may invest the interest received and the collateral,  thereby earning additional
income.  Loans  would be  subject to  termination  by the  lending  Fund on four
business  days'  notice  or by  the  borrower  on  one  day's  notice.  Borrowed
securities must be returned when the loan is terminated. Any gain or loss in the
market price of the borrowed  securities that occurs during the term of the loan
inures to the lending Fund and that Fund's shareholders.  A lending Fund may pay
reasonable finders,  borrowers,  administrative and custodial fees in connection
with a loan.  Each Fund  currently  has no  intention  of lending its  portfolio
securities.

INVESTMENTS IN OTHER INVESTMENT COMPANIES
- -----------------------------------------
Each Fund may invest in the  securities  of other  investment  companies  to the
extent that such an investment  would be consistent with the requirements of the
1940 Act. The Money Market Fund will invest only in those  investment  companies
that  invest  in the same  quality  of  investments  as the Money  Market  Fund.
Investments  in  the  securities  of  other  investment  companies  may  involve
duplication of advisory fees and certain other expenses. By investing in another
investment  company, a Fund becomes a shareholder of that investment company. As
a result, Fund shareholders indirectly will bear a Fund's proportionate share of


                                       12
<PAGE>


the fees and expenses paid by shareholders of the other investment  company,  in
addition to the fees and expenses Fund shareholders  directly bear in connection
with the Fund's own operations.

ILLIQUID INVESTMENTS AND RESTRICTED SECURITIES
- ----------------------------------------------
Each Fund will not purchase or  otherwise  acquire any security if, as a result,
more  than 15% (10% for the  Money  Market  Fund) of its net  assets  (taken  at
current value) would be invested in  investments  that are illiquid by virtue of
the absence of a readily  available market or legal or contractual  restrictions
on resale.  This policy  does not include  restricted  securities  eligible  for
resale pursuant to Rule 144A under the Securities Act of 1933, as amended ("1933
Act"),  which the  Board or the  Adviser  has  determined  under  Board-approved
guidelines  are  liquid.  None  of the  Funds,  however,  currently  anticipates
investing in such restricted securities.

The term "illiquid  investments" for this purpose means  investments that cannot
be  disposed  of  within  seven  days in the  ordinary  course  of  business  at
approximately the amount at which a Fund has valued the investments. Investments
currently  considered to be illiquid  include:  (1)  repurchase  agreements  not
terminable within seven days, (2) securities for which market quotations are not
readily  available,  (3) OTC options and their underlying  collateral,  (4) bank
deposits,  unless they are payable at principal  amount plus accrued interest on
demand  or within  seven  days  after  demand,  (5)  restricted  securities  not
determined to be liquid pursuant to guidelines established by the Board, and (6)
securities involved in swap, cap, floor and collar transactions. The assets used
as cover for OTC options  written by a Fund will be considered  illiquid  unless
the OTC  options  are sold to  qualified  dealers  who  agree  that the Fund may
repurchase  any OTC option it writes at a maximum  price to be  calculated  by a
formula set forth in the option  agreement.  The cover for an OTC option written
subject to this procedure  would be considered  illiquid only to the extent that
the maximum  repurchase  price under the formula  exceeds the intrinsic value of
the option.

A Fund may not be able to sell illiquid  investments when the Adviser  considers
it  desirable to do so or may have to sell such  investments  at a price that is
lower than the price that could be obtained if the investments  were liquid.  In
addition,  the sale of illiquid  investments may require more time and result in
higher  dealer  discounts  and  other  selling  expenses  than  does the sale of
investments  that  are  not  illiquid.  Illiquid  investments  also  may be more
difficult to value due to the  unavailability  of reliable market quotations for
such  investments,  and investment in illiquid  investments  may have an adverse
impact on net asset value.

Rule 144A under the 1933 Act  establishes a "safe harbor" from the  registration
requirements  of the 1933 Act for  resales of certain  securities  to  qualified
institutional buyers.  Institutional markets for restricted securities that have
developed as a result of Rule 144A provide both readily ascertainable values for
certain  restricted  securities  and the ability to liquidate an  investment  to
satisfy  share   redemption   orders.   An  insufficient   number  of  qualified
institutional buyers interested in purchasing Rule 144-eligible  securities held
by a Fund,  however,  could affect adversely the marketability of such portfolio
securities and a Fund may be unable to dispose of such securities promptly or at
reasonable prices.

PORTFOLIO TURNOVER
- ------------------
As discussed in the  Prospectus,  the Trust  anticipates  that  investors in the
Funds,  as part of an asset  allocation  investment  strategy,  frequently  will
redeem Fund  shares,  as well as exchange  their Fund shares for shares of other
Funds. A Fund may have to dispose of certain  portfolio  investments to maintain


                                       13
<PAGE>



sufficient liquid assets to meet such redemption and exchange requests,  thereby
causing a high portfolio turnover.

A Fund's  portfolio  turnover rate is calculated by the value of the  securities
purchased or securities  sold,  excluding all securities whose maturities at the
time of acquisition were one year or less,  divided by the average monthly value
of such securities owned during the year. Based on this calculation, instruments
with remaining  maturities of less than one year are excluded from the portfolio
turnover rate. Such  instruments  generally would include futures  contracts and
options,  since such contracts  generally have a remaining maturity of less than
one year. In any given period,  all of a Fund's investments may have a remaining
maturity of less than one year; in which case,  the portfolio  turnover rate for
that period  would be equal to zero.  However,  each Fund's  portfolio  turnover
rate,  except for the Money Market Fund,  calculated  with all securities  whose
maturities were one year or less is anticipated to be unusually high.


                             INVESTMENT RESTRICTIONS

In addition to the  investment  policies  and  limitations  described  above and
described  in the  Prospectus,  each Fund has adopted the  following  investment
limitations,  which are fundamental  policies and may not be changed without the
vote of a majority of the outstanding  voting securities of that Fund. Under the
1940 Act, a "vote of the majority of the  outstanding  voting  securities"  of a
Fund  means the  affirmative  vote of the  lesser  of:  (1) more than 50% of the
outstanding  shares of a Fund or (2) 67% or more of the shares of a Fund present
at a  shareholders  meeting  if more  than  50% of the  outstanding  shares  are
represented at the meeting in person or by proxy.

For purposes of the following  limitations,  all  percentage  limitations  apply
immediately  after a purchase  or initial  investment.  Except  with  respect to
borrowing  money,  if a percentage  limitation  is adhered to at the time of the
investment,  a later increase or decrease in the  percentage  resulting from any
change  in  value  or  net  assets  will  not  result  in a  violation  of  such
restrictions. If at any time a Fund's borrowings exceed its limitations due to a
decline in net assets,  such borrowings  will be reduced  promptly to the extent
necessary to comply with the limitation.

EACH FUND HAS ADOPTED THE FOLLOWING  FUNDAMENTAL  INVESTMENT POLICY that enables
it  to  invest  in  another  investment  company  or  series  thereof  that  has
substantially similar investment objectives and policies:

      Notwithstanding  any  other  limitation,  the Fund may  invest  all of its
      investable  assets  in an  open-end  management  investment  company  with
      substantially the same investment objectives,  policies and limitations as
      the Fund. For this purpose,  "all of the Fund's  investable  assets" means
      that the only investment  securities that will be held by the Fund will be
      the Fund's interest in the investment company.

EACH FUND,  EXCEPT THE MONEY MARKET FUND,  HAS ADOPTED THE FOLLOWING  INVESTMENT
LIMITATIONS:

A Fund shall not:


                                       14

1.   Lend any security or make any other loan if, as a result, more than 33 1/3%
     of the value of the Fund's  total  assets  would be lent to other  parties,
     except (1) through the purchase of a portion of an issue of debt securities
     in  accordance  with  the  Fund's   investment   objective,   policies  and
     limitations,  or (2) by engaging in repurchase  agreements  with respect to
     portfolio securities.

     (1)  that  the  Fund  may  issue  senior   securities  in  connection  with
     transactions in options,  futures,  options on futures,  forward contracts,
     swaps,  caps,  floors,  collars  and  other  similar  investments,  (2)  as
     otherwise permitted herein and in Investment  Limitations Nos. 5, 7, and 8,

EACH FUND,  EXCEPT THE U.S.  PLUS FUND AND THE OTC PLUS FUND,  HAS  ADOPTED  THE
FOLLOWING INVESTMENT LIMITATION:

     the Fund's total assets,  including the amount  borrowed,  in order to meet
     redemption requests without immediately selling portfolio  securities,  (3)
     to enter into  reverse  repurchase  agreements,  and (4) to lend  portfolio
     securities.  For purposes of this  investment  limitation,  the purchase or

     contracts,  swaps,  caps, floors,  collars and other financial  instruments
     shall not constitute borrowing.

     currently  limits  borrowing  to no more  than 33 1/3% of the  value of the
     Fund's total assets),  (2) as a temporary  measure and then only in amounts
     not to exceed 5% of the value of the Fund's total assets, (3) to enter into
     reverse repurchase  agreements,  and (4) to lend portfolio securities.  For
     purposes of this  investment  limitation,  the purchase or sale of options,
     futures contracts,  options on futures contracts, forward contracts, swaps,
     caps, floors,  collars and other financial instruments shall not constitute
     borrowing.

EACH FUND,  EXCEPT THE OTC PLUS FUND AND THE  OTC/SHORT  FUND,  HAS  ADOPTED THE
FOLLOWING INVESTMENT LIMITATION:

     its agencies or instrumentalities.

2.   Lend the Fund's portfolio  securities in excess of 15% of its total assets.
     Any loans of the Fund's  portfolio  securities  will be made  according  to

<PAGE>



     guidelines  established by the Trustees,  including the maintenance of cash

     investment limitation does not prevent the Fund from purchasing and selling
     options,   futures  contracts,   options  on  futures  contracts,   forward
     contracts, swaps, caps, floors, collars and other financial instruments.

7.   Invest in securities of other  investment  companies,  except to the extent

     floors, collars and other financial instruments.  In those cases, the Money
     Market Fund may mortgage,  pledge,  or  hypothecate  assets having a market
     value not exceeding the lesser of the dollar amount  borrowed or 15% of the
     value  of  total  assets  of the  Money  Market  Fund  at the  time  of the
     borrowing.

9.   Make  short  sales  of  portfolio  securities  or  purchase  any  portfolio
     securities  on  margin,  except to obtain  such  short-term  credits as are
     necessary for the clearance of purchases and sales of securities; provided,
     HOWEVER,  that this  investment  limitation  does not prevent the Fund from
     purchasing  and  selling  options,  futures  contracts,  options on futures
     contracts,  forward  contracts,  swaps,  caps,  floors,  collars  and other
     financial instruments.

In  addition,  the Money Market Fund does not  presently  intend to purchase and
sell foreign currency, options, futures contracts, options on futures contracts,
forward contracts, swaps, caps, floors and collars.


                      PORTFOLIO TRANSACTIONS AND BROKERAGE

Subject to the general  supervision by the Trustees,  the Adviser is responsible
for  decisions  to buy and sell  securities  for each  Fund,  the  selection  of
broker-dealers  to effect the  transactions,  and the  negotiation  of brokerage
commissions, if any. The Adviser expects that the Funds may execute brokerage or
other agency transactions through registered  broker-dealers,  for a commission,
in  conformity  with the 1940  Act,  the  Securities  Exchange  Act of 1934,  as
amended, and the rules and regulations thereunder.

In  effecting  portfolio  transactions  for the Funds,  the  Adviser  seeks best
execution  of  trades  either  (1) at the most  favorable  price  and  efficient
execution  of  transactions,  or (2) with respect to agency  transactions,  at a
higher rate of  commission  if  reasonable in relation to brokerage and research
services  provided to the Funds or the  Adviser.  Such  services may include the
following:  information  as to the  availability  of securities  for purchase or
sale;  statistical or factual  information or opinions pertaining to investment;


                                       17
<PAGE>



wire services; and appraisals or evaluations of portfolio securities.  Each Fund
believes that the requirement always to seek the lowest possible commission cost
could  impede  effective  portfolio  management  and  preclude  the Fund and the
Adviser from  obtaining a high quality of brokerage  and research  services.  In
seeking to determine the  reasonableness  of brokerage  commissions  paid in any
transaction,  the Adviser  relies upon its  experience  and knowledge  regarding
commissions  generally  charged  by  various  brokers  and  on its  judgment  in
evaluating  the  brokerage  and  research  services  received  from  the  broker
effecting the transaction.

The Adviser may use research and services provided to it by brokers in servicing
all the Funds;  however,  not all such  services  may be used by the  Adviser in
connection  with a Fund.  While the receipt of such  information and services is
useful in varying  degrees and generally  would reduce the amount of research or
services otherwise performed by the Adviser, this information and these services
are of  indeterminable  value and  would not  reduce  the  Adviser's  investment
advisory fee to be paid by the Funds.

Purchases  and  sales of U.S.  Government  Securities  normally  are  transacted
through  issuers,  underwriters or major dealers in U.S.  Government  Securities
acting  as  principals.  Such  transactions  are made on a net  basis and do not
involve payment of brokerage commissions.  The cost of securities purchased from
an  underwriter  usually  includes  a  commission  paid  by  the  issuer  to the
underwriters;  transactions with dealers normally reflect the spread between bid
and asked prices.

*  Messrs.  Rafferty and Higgins are deemed to be "interested  persons" of the
   Trust, as defined by the 1940 Act.

The  Trustees and  officers of the Trust,  as a group,  own less than 1% of each
Fund's shares  outstanding.  The Trust's  Declaration of Trust provides that the
Trustees  will not be liable for errors of  judgment or mistakes of fact or law.
However,  they are not  protected  against  any  liability  to which  they would
otherwise  be  subject  by reason  of  willful  misfeasance,  bad  faith,  gross
negligence or reckless  disregard of the duties involved in the conduct of their
office.

The Trust will pay the Trustees who are not "interested persons" of the Trust as
defined by the 1940 Act ("Independent  Trustees") $500 per meeting of the Board.
The Adviser will pay Mr. Higgins similar  compensation per meeting of the Board.
Trustees  also are  reimbursed  for any  expenses  incurred in  attending  Board
meetings.  None of the Trustees have  previously or currently serve as a Trustee
or in a comparable  capacity for any other  registered  investment  company and,
thus, have not received any prior compensation for such service.

INVESTMENT ADVISER
- ------------------
The Funds' investment adviser, Rafferty Asset Management,  LLC, was organized as
a New York  limited  liability  corporation  in  1997.  The  Adviser  is a newly
registered  investment adviser and has no prior experience  advising  investment
companies. The Adviser is controlled by Lawrence C. Rafferty.

Under an  Investment  Advisory  Agreement  between  the Trust,  on behalf of the
Funds, and the Adviser ("Advisory Agreement"), the Adviser provides a continuous
investment  program for each Fund's  assets in  accordance  with its  investment
objectives,  policies and limitations, and oversees the day-to-day operations of
the Funds,  subject to the  supervision  of the Trustees.  The Adviser bears all
costs associated with providing these advisory  services and the expenses of the
Trustees who are affiliated with or interested persons of the Adviser. The Trust
bears all other expenses that are not assumed by the Adviser as described in the
Prospectus.  The Trust also is liable for  nonrecurring  expenses  as may arise,


                                       20
<PAGE>


including  litigation to which a Fund may be a party. The Trust also may have an
obligation  to indemnify  its  Trustees  and  officers  with respect to any such
litigation.

Pursuant to the Advisory Agreement, each Fund pays the Adviser the following fee
at an annual  rate  based on its  average  daily  net  assets  of:  0.75% of the
Japan/Long  Fund,  U.S.  Plus Fund and OTC Plus Fund;  0.90% of the  Japan/Short
Fund, U.S./Short Fund and OTC/Short Fund; and 0.50% of the Money Market Fund.

The Advisory  Agreement was approved by the Trustees  (including all Independent
Trustees) and the Adviser,  as sole shareholder of each Fund, in compliance with
the 1940 Act. The Advisory  Agreement will continue in force for a period of two
years after the date of its approval. The Agreement is renewable thereafter from
year to year with respect to each Fund, so long as its  continuance  is approved
at least  annually (1) by the vote,  cast in person at a meeting called for that
purpose, of a majority of those Trustees who are not "interested persons" of the
Adviser or the Trust,  or (2) by the  majority  vote of either the full Board or
the  vote of a  majority  of the  outstanding  shares  of a Fund.  The  Advisory
Agreement  automatically  terminates on assignment and is terminable on 60 days'
written notice either by the Trust or the Adviser.

FUND ADMINISTRATOR,  FUND ACCOUNTANT, TRANSFER AGENT AND CUSTODIAN 
- ------------------------------------------------------------------
Firstar Trust Company, 615 East Michigan Street, Milwaukee, Wisconsin 53202,
provides administrative, fund accounting, transfer agent and custodian services
to the Funds.

Pursuant to an Administration  Servicing Agreement ("Service Agreement") between
the  Trust  and  Firstar  Trust  Company  ("Administrator"),  the  Administrator
provides  the Trust with  administrative  and  management  services  (other than
investment  advisory  services).  As compensation for these services,  the Trust
pays the  Administrator  a fee of .06% of the first  $200,000,000 of the Trust's
average daily net assets,  .05% of the next  $300,000,000 of the Trust's average
daily net assets,  and .03% of the Trust's average daily net assets in excess of
$500,000,000.  Notwithstanding the foregoing, the Administrator's minimum annual
fee is $170,000.

Pursuant to a Fund Accounting  Servicing Agreement between the Trust and Firstar
Trust Company ("Fund  Accountant"),  the Fund Accountant provides the Trust with
accounting services,  including portfolio  accounting  services,  tax accounting
services and furnishing  financial reports.  For these services,  the Trust pays
the Fund  Accountant  a flat fee of $25,000 for the first $40 million of average
daily net  assets  for each the  Japan/Long,  Japan/Short,  OTC/Short  and Money
Market Funds;  and $22,000 for the first $40 million of average daily net assets
for each the U.S. Plus,  U.S./Short and OTC Plus Funds. The Fund Accountant also
is entitled to certain out-of-pocket expenses, including pricing expenses.

Pursuant to a Custodian  Agreement,  Firstar  Trust Company  ("Custodian")  also
serves as the Custodian of the Funds'  assets.  Under the terms of the Custodian
Agreement,  the  Custodian  holds  and  administers  the  assets  in the  Funds'
portfolios.

DISTRIBUTOR
- -----------
First   Data   Distributors,   Inc.,   4400   Computer   Drive,   Westborough,
Massachusetts  01581, serves as the distributor  ("Distributor") in connection
with the offering of each Fund's shares on a no-load  basis.  The  Distributor
currently receives from the Adviser a fee of $10,000.


                                       21

DISTRIBUTION PLAN
- -----------------
Rule 12b-1  under the 1940 Act  provides  that an  investment  company  may bear
expenses  of  distributing  its  shares  only  pursuant  to a  plan  adopted  in
accordance with the Rule. The Trustees have adopted such a plan (the "Plan") for
each Fund  pursuant  to which the Funds would  compensate  the  Distributor  for
certain  expenses  incurred in the  distribution  of that Fund's  shares and the
servicing and maintenance of existing Fund shareholder accounts. Pursuant to the
Plan,  a Fund  may  pay the  Distributor  a  service  fee of up to  0.25%  and a
distribution fee of up to 0.75% of the Fund's average daily net assets. However,
the Trustees have not  authorized  payment of any fees pursuant to the Plan. The
Trustees  will  authorize  such  payments only when they believe that there is a
reasonable likelihood that the Plan will benefit each Fund and its shareholders.
If the Trustees do authorize  payment of fees pursuant to the Plan, the Trustees
will review quarterly and annually a written report provided by the Treasurer of
the amounts expended under the Plan and the purposes for which such expenditures
were made.

The Plan will continue in effect,  with respect to a Fund,  from year to year as
long as its continuance is approved annually by either the Trustees or by a vote
of a majority of the outstanding voting securities of that Fund. In either case,
to continue,  the Plan must be approved by the vote of a majority of Independent
Trustees.  The Plan can be terminated,  with respect to a Fund, at any time by a
vote of a majority of the Independent Trustees or by a vote of a majority of the
outstanding voting securities of that Fund.

INDEPENDENT ACCOUNTANTS
- -----------------------
Price  Waterhouse  LLP,  100  East  Wisconsin  Avenue,  Suite  1500,  Milwaukee,
Wisconsin 53202, are the auditors and the independent accountants for the Trust.


                        DETERMINATION OF NET ASSET VALUE

As described in the  Prospectus,  the net asset value per share of the U.S. Plus
Fund,  the  U.S./Short  Fund,  the  OTC  Plus  Fund  and the  OTC/Short  Fund is
determined  daily,  Monday through Friday,  each day the New York Stock Exchange
("NYSE") is open for business,  which excludes New Year's Day,  Presidents' Day,
Martin Luther King's  Birthday,  Good Friday,  Memorial Day,  Independence  Day,
Labor Day, Thanksgiving Day, and Christmas Day. The net asset value per share of
the  Japan  Plus  Fund  and the  Japan/Short  Fund is  determined  each  day the
Singapore  International  Monetary  Exchange  ("SIMEX")  is open  for  business.
Trading  on the SIMEX may not take  place on all days on which the NYSE is open.
The SIMEX is closed on the  following  Japanese  holidays:  New Year's Day,  New
Year's Holiday, Bank Holiday, Coming-of-Age Day, National Foundation Day, Vernal
Equinox Day,  Greenery Day,  Constitution  Memorial Day,  Children's Day, Marine
Day,  Respect-for-the-Aged Day, Autumnal Equinox Day, Health-Sports Day, Culture
Day, Labor Thanksgiving Day and the Emperor's Birthday.  The net asset value per
share of the Money Market Fund is determined each day that both the NYSE and the
Federal Reserve Bank of New York are open for business.

It is the policy of the Money  Market  Fund to  attempt  to  maintain a constant
price per share of $1.00. There can be no assurance that a $1.00 net asset value
per share will be maintained. The portfolio instruments held by the Money Market
Fund are valued based on the amortized  cost valuation  method  pursuant to Rule
2a-7 under the 1940 Act.  This  involves  valuing an  instrument at its cost and


                                       22
<PAGE>



thereafter  assuming a constant  amortization  to  maturity  of any  discount or
premium,  even though the portfolio  security may increase or decrease in market
value. Such fluctuations generally are in response to changes in interest rates.
Use of the amortized  cost  valuation  method  requires the Money Market Fund to
purchase  instruments  having  remaining  maturities  of 397  days or  less,  to
maintain a dollar-weighted average portfolio maturity of 90 days or less, and to
invest only in securities  determined by the Trustees to be of high quality with
minimal credit risks. The Money Market Fund may invest in issuers or instruments
that at the time of purchase have received the highest  short-term rating by any
two nationally recognized statistical rating organizations ("NRSROs").

Rule 2a-7 requires the Trustees to establish  procedures  reasonably designed to
stabilize the net asset value per share as computed for purposes of distribution
and  redemption.  The Board's  procedures  include  monitoring the  relationship
between the amortized cost value per share and a net asset value per share based
upon available  indications of market value. The Board will decide what, if any,
steps should be taken if there is a difference  of more than .5% between the two
methods.  The Board  will  take any steps  they  consider  appropriate  (such as
redemption in kind or shortening the average portfolio maturity) to minimize any
material  dilution or other unfair results arising from differences  between the
two methods of determining net asset value.

A security  listed or traded on an exchange,  domestic or foreign,  is valued at
its last sales price on the  principal  exchange on which it is traded  prior to
the time when assets are valued.  If no sale is reported at that time,  the most
recent  bid price is used.  When  market  quotations  for  options  and  futures
positions held by a Fund are readily  available,  those positions will be valued
based  upon such  quotations.  Securities  and  other  assets  for which  market
quotations  are not  readily  available,  or for which the Adviser has reason to
question  the  validity  of  quotations  received,  are  valued at fair value as
determined  in good faith by the Board.  For valuation  purposes,  quotations of
foreign  securities  or other  assets  denominated  in  foreign  currencies  are
translated to U.S.  Dollar  equivalents  using the net foreign  exchange rate in
effect at the close of the stock  exchange in the country  where the security is
issued.  Short-term  investments having a maturity of 60 days or less are valued
at amortized cost, which approximates market value.


                             PERFORMANCE INFORMATION

Each  Fund's   performance  data  quoted  in  reports,   advertising  and  other
promotional  materials  represents  past  performance  and  is not  intended  to
indicate future performance.  The investment return and principal value for each
Fund,  except for the Money Market Fund,  will  fluctuate so that an  investor's
shares, when redeemed, may be worth more or less than their original costs.

COMPARATIVE INFORMATION
- -----------------------
From time to time, each Fund's performance may be compared with recognized stock
and other  indices,  such as the Standard & Poor's  Composite  Stock Price Index
("S&P 500 Index"),  the Dow Jones Industrial  Average  ("DJIA"),  the Nasdaq 100
Stock  IndexTM  ("Nasdaq  Index"),  and the Nasdaq  Composite  IndexTM  ("Nasdaq
Composite"),  the Nikkei 225 Stock  Average  ("Nikkei  Index") and various other
domestic,  international and global indices.  The S&P 500 Index is a broad index
of common  stock  prices,  while  the DJIA  represents  a  narrower  segment  of


                                       23
<PAGE>


industrial  companies.   Each  assumes  reinvestment  of  distributions  and  is
calculated without regard to tax consequences or operating expenses.  The Nasdaq
Composite  comparison may be provided to show how the OTC/Long and the OTC/Short
Funds'  total  returns  compare  to the  record of a broad  average of OTC stock
prices over the same  period.  The  OTC/Long  and the  OTC/Short  Funds have the
ability to invest in  securities  not included in the Nasdaq Index or the Nasdaq
Composite, and the OTC/Long and the OTC/Short Funds' investment portfolio may or
may not be similar in composition to the Nasdaq Index or the Nasdaq Composite.

In addition,  a Fund's total return may be compared to the  performance of broad
groups of comparable mutual funds with similar  investment  objectives,  as such
performance is tracked and published by such independent organizations as Lipper
Analytical Services, Inc. ("Lipper"), and CDA Investment Technologies, Inc. When
Lipper's  tracking  results  are used,  the Fund will be  compared  to  Lipper's
appropriate  fund category,  that is, by fund objective and portfolio  holdings.
Accordingly,  the Lipper ranking and comparison,  which may be used by the Trust
in  performance  reports,  will be drawn from the "Capital  Appreciation  Funds"
grouping for the U.S. Plus Fund and the U.S./Short Fund, from the "Small Company
Growth Funds"  grouping for the OTC/Long and the OTC/Short  Funds,  and from the
"International  Funds"  grouping for the Japan/Long and the  Japan/Short  Funds.
Since the assets in all mutual funds are always  changing,  a Fund may be ranked
within one Lipper  asset-size class at one time and in another Lipper asset-size
class at some  other  time.  Footnotes  in  advertisements  and other  marketing
literature  will  include  the time  period  and  Lipper  asset-size  class,  as
applicable,  for the  ranking  in  question.  Performance  figures  are based on
historical results and are not intended to indicate future performance.

TOTAL RETURN COMPUTATIONS
- -------------------------
For purposes of quoting and comparing the performance of a Fund to that of other
mutual  funds and to other  relevant  market  indices  in  advertisements  or in
reports  to  shareholders,  performance  for the Fund may be  stated in terms of
total  return.  Such  average  annual  total  return  quotes  for the  Funds are
calculated according to the following formula:

                                 P(1+T)[SUPERSCRIPT]n=ERV

      Where:    P =  a hypothetical initial payment of $1,000
                T =  average annual total return
                n =  number of years (either 1, 5 or 10)
              ERV =  ending redeemable value of a hypothetical  $1,000 payment
                     made at the  beginning of the 1, 5 or 10 year  periods,  as
                     applicable, at the end of that period

Under the foregoing formula,  the time periods used in advertising will be based
on rolling calendar quarters, updated to the last day of the most recent quarter
prior to submission of the advertising for publication,  and will cover 1, 5 and
10 year periods or a shorter  period  dating from the  commencement  of a Fund's
operations.  In  calculating  the ending  redeemable  value,  all  dividends and
distributions  by a Fund are assumed to have been  reinvested at net asset value
on the reinvestment dates during the period. Total return, or "T" in the formula
above, is computed by finding the average annual compounded rates of return over
the 1, 5 and 10 year periods (or fractional  portion  thereof) that would equate
the initial amount invested to the ending redeemable value.


                                       24
<PAGE>



From time to time, each Fund also may include in such advertising a total return
figure that is not calculated  according to the formula set forth above in order
to compare more  accurately  the  performance  of a Fund with other  measures of
investment  return.  For example,  in comparing  the total return of a Fund with
data published by Lipper or with such market  indices as the  performance of (1)
the S&P 500 Index or the DJIA for the U.S. Plus and the  U.S./Short  Funds,  (2)
the Nasdaq Index for the OTC/Long and the  OTC/Short  Funds;  and (3) the Nikkei
Index  for the  Japan/Long  and the  Japan/Short  Funds,  each  respective  Fund
calculates  its  aggregate  total  return for the  specified  periods of time by
assuming an investment  of $10,000 in Fund shares and assuming the  reinvestment
of each dividend or other  distribution  at net asset value on the  reinvestment
date.  Percentage  increases are determined by subtracting  the initial value of
the  investment  from the ending  value and by  dividing  the  remainder  by the
beginning value.

YIELD COMPUTATIONS
- ------------------
The Money Market Fund's annualized  current yield, as may be quoted from time to
time in  advertisements  and other  communications to shareholders and potential
investors,  is computed for a seven-day  period by  determining  the net change,
exclusive  of capital  changes  and  including  the value of  additional  shares
purchased with  dividends and any dividends  declared  therefrom  (which reflect
deductions of all expenses of the Fund such as advisory fees), in the value of a
hypothetical  preexisting account having a balance of one share at the beginning
of the period,  subtracting a hypothetical  charge  reflecting  deductions  from
shareholder accounts, and dividing the difference by the value of the account at
the  beginning  of the base  period to obtain the base period  return,  and then
multiplying the base period return by (365/7).

The Money Market Fund's  annualized  effective yield, as may be quoted from time
to time in advertisements and other communications to shareholders and potential
investors,  is computed by determining  (for the same stated seven-day period as
the current  yield) the net change,  exclusive of capital  changes and including
the value of  additional  shares  purchased  with  dividends  and any  dividends
declared therefrom (which reflect deductions of all expenses of the Fund such as
advisory  fees),  in the value of a  hypothetical  preexisting  account having a
balance of one share at the beginning of the period, and dividing the difference
by the value of the  account at the  beginning  of the base period to obtain the
base period  return,  and then  compounding  the base period return by adding 1,
raising the sum to a power equal to 365 divided by 7, and subtracting 1 from the
result, according to the following formula:

            Effective Yield = [(Base Period Return + 1) 365/7] - 1

The yields  quoted in any  advertisement  or other  communication  should not be
considered a representation of the yields of the Money Market Fund in the future
since the yield is not fixed.  Actual  yields  will depend not only on the type,
quality,  and  maturities of the  investments  held by the Money Market Fund and
changes in interest rates on such investments,  but also on changes in the Money
Market Fund's expenses during the period.

Yield information may be useful in reviewing the performance of the Money Market
Fund  and  for  providing  a  basis  for   comparison   with  other   investment
alternatives.   However,  unlike  bank  deposits  or  other  investments,  which
typically pay a fixed yield for a stated period of time, the Money Market Fund's
yield will fluctuate.

                   DIVIDENDS, OTHER DISTRIBUTIONS AND TAXES

DIVIDENDS AND OTHER DISTRIBUTIONS
- ---------------------------------
Dividends  from net  investment  income and any  distributions  of realized  net
capital  gains  and  net  gains  from  foreign  currency  transactions  will  be
distributed  as  described  in  the  Prospectus   under   "Dividends  and  Other
Distributions."  All  distributions  from a Fund normally will be  automatically
reinvested without charge in additional shares of that Fund.

As discussed in the  Prospectus,  the Money Market Fund  ordinarily will declare
dividends  daily  from net  investment  income  and  distribute  such  dividends
monthly. Net income, for these purposes, includes accrued interest and accretion
of original issue and market discounts,  less amortization of market premium and
estimated   expenses,   and  will  be  calculated   immediately   prior  to  the
determination  of the Fund's net asset value per share. The Fund distributes its
net  short-term  capital  gain,  if any,  annually  but may make  more  frequent
distributions  thereof if necessary to maintain its net asset value per share at
$1.00 or to avoid  income or excise  taxes.  The Fund does not expect to realize
net  long-term  capital  gain  and  thus  does  not  anticipate  payment  of any
distributions of net capital gain (the excess of net long-term capital gain over
net short-term  capital loss). The Trustees may revise this dividend policy,  or
postpone  the payment of  dividends,  if the Fund has or  anticipates  any large
unexpected  expense,  loss, or  fluctuation in net assets that, in the Trustees'
opinion, might have a significant adverse effect on its shareholders.

TAXES
- -----
REGULATED  INVESTMENT  COMPANY  STATUS.  To qualify for treatment as a regulated
investment  company ("RIC") under the Internal  Revenue Code of 1986, as amended
("Code"),  each Fund -- which is  treated as a  separate  corporation  for these
purposes -- must distribute to its  shareholders  for each taxable year at least
90% of its  investment  company  taxable  income  (consisting  generally  of net
investment  income,  net  short-term  capital  gain,  and net gains from certain
foreign  currency  transactions)  ("Distribution  Requirement")  and  must  meet
several additional  requirements.  For each Fund, these requirements include the
following:  (1) the Fund  must  derive at least  90% of its  gross  income  each
taxable year from  dividends,  interest,  payments  with  respect to  securities
loans,  and gains from the sale or other  disposition  of  securities or foreign
currencies,  or other income (including gains from options,  futures, or forward
contracts)  derived with respect to its business of investing in  securities  or
those currencies ("Income Requirement"); and (2) at the close of each quarter of
the Fund's  taxable year, (i) at least 50% of the value of its total assets must
be represented by cash and cash items, U.S. Government Securities, securities of
other RICs,  and other  securities,  with those  other  securities  limited,  in
respect of any one issuer,  to an amount that does not exceed 5% of the value of
the  Fund's  total  assets  and that  does not  represent  more  than 10% of the
issuer's outstanding voting securities,  and (ii) not more than 25% of the value
of its total assets may be invested in  securities  (other than U.S.  Government
Securities  or the  securities  of other RICs) of any one issuer  (collectively,
"Diversification Requirements").

Although the Funds intend to satisfy all the foregoing requirements, there is no
assurance  that each Fund will be able to do so. The  investment by a Fund other
than the Money Market Fund  primarily in options and futures  positions  entails
some  risk  that  such  a  Fund  might  fail  to  satisfy  the   Diversification
Requirements.  There  is  some  uncertainty  regarding  the  valuation  of  such
positions for purposes of those requirements;  accordingly,  it is possible that
the method of valuation used by the Funds,  pursuant to which each of them would
be treated as satisfying the Diversification Requirements, would not be accepted


                                       26
<PAGE>



in an audit by the  Internal  Revenue  Service,  which  would  apply a different
method resulting in disqualification of one or more of those Funds.

GENERAL.  If Fund  shares are sold at a loss after  being held for six months or
less, the loss will be treated as long-term, instead of short-term, capital loss
to the  extent of any  capital  gain  distributions  received  on those  shares.
Investors  also should be aware that if shares are purchased  shortly before the
record date for any dividend or capital gain distribution,  the shareholder will
pay full price for the shares and receive  some  portion of the  purchase  price
back as a taxable distribution.

Each Fund will be subject to a nondeductible 4% excise tax ("Excise Tax") to the
extent it fails to distribute by the end of any calendar year  substantially all
of its  ordinary  income  for that  year and  capital  gain net  income  for the
one-year period ending on October 31 of that year, plus certain other amounts.

INCOME  FROM  FOREIGN  SECURITIES.   Dividends  and  interest  received  by  the
Japan/Long  Fund and  dividends  received  by the  Japan/Short  Fund,  and gains
realized  by each such Fund,  may be subject  to income,  withholding,  or other
taxes imposed by foreign  countries and U.S.  possessions  that would reduce the
yield and/or total return on their securities.  Tax conventions  between certain
countries  and the United States may reduce or eliminate  these  foreign  taxes,
however,  and many foreign  countries  do not impose  taxes on capital  gains in
respect of investments by foreign investors.

The  Japan/Long  Fund may  invest in the stock of  "passive  foreign  investment
companies"  ("PFICs").  A  PFIC  is  a  foreign  corporation  --  other  than  a
"controlled  foreign  corporation" (I.E., a foreign corporation in which, on any
day during its  taxable  year,  more than 50% of the total  voting  power of all
voting stock therein or the total value of all stock therein is owned, directly,
indirectly,  or constructively,  by "U.S. shareholders," defined in the singular
as a U.S. person that owns, directly,  indirectly,  or constructively,  at least
10% of that voting power) as to which the Fund is a U.S. shareholder  (effective
for the Fund's taxable years  beginning  after 1997) -- that, in general,  meets
either of the following  tests:  (1) at least 75% of its gross income is passive
or (2) an  average of at least 50% of its  assets  produce,  or are held for the
production of, passive  income.  Under certain  circumstances,  the Fund will be
subject to Federal income tax on a portion of any "excess distribution" received
on the stock of a PFIC or of any gain on disposition of the stock (collectively,
"PFIC income"),  plus interest  thereon,  even if the Fund  distributes the PFIC
income as a taxable dividend to its shareholders. The balance of the PFIC income
will  be  included  in  the  Fund's  investment   company  taxable  income  and,
accordingly,  will not be taxable to it to the extent that income is distributed
to its shareholders.  If the Fund invests in a PFIC and elects to treat the PFIC
as a "qualified  electing fund" ("QEF"),  then, in lieu of the foregoing tax and
interest  obligation,  the Fund would be required to include in income each year
its PRO RATA share of the QEF's annual ordinary earnings and net capital gain --
which  probably  would  have  to be  distributed  by the  Fund  to  satisfy  the
Distribution Requirement and avoid imposition of the Excise Tax -- even if those
earnings and gain were not received by the Fund from the QEF. In most  instances
it will be very difficult,  if not impossible,  to make this election because of
certain requirements thereof.

Effective for its taxable years  beginning  after 1997, the Japan/Long  Fund may
elect to "mark to market"  its stock in any PFIC.  "Marking-to-market,"  in this
context,  means  including in ordinary  income each taxable year the excess,  if
any, of the fair market value of the PFIC's stock over the Fund's adjusted basis
therein  as of the end of that year.  Pursuant  to the  election,  the Fund also
would be allowed to deduct (as an ordinary,  not capital,  loss) the excess,  if
any, of its adjusted  basis in PFIC stock over the fair market value  thereof as


                                       27
<PAGE>



of the taxable year-end,  but only to the extent of any net mark-to-market gains
with respect to that stock  included by the Fund for prior  taxable  years.  The
Fund's  adjusted  basis in each PFIC's stock with respect to which it makes this
election  would be  adjusted  to  reflect  the  amounts of income  included  and
deductions taken under the election.  Regulations proposed in 1992 would provide
a similar election with respect to the stock of certain PFICs.

Gains or losses (1) from the  disposition  of foreign  currencies,  (2) from the
disposition of debt  securities  denominated  in foreign  currency that, in each
instance,  are attributable to fluctuations in the value of the foreign currency
between the date of  acquisition  of the  security  and the date of  disposition
thereof,  and (3) that are  attributable  to fluctuations in exchange rates that
occur between the time a Fund accrues dividends,  interest, or other receivables
or expenses or other liabilities  denominated in a foreign currency and the time
the Fund actually  collects the receivables or pays the  liabilities,  generally
will be treated as ordinary income or loss.  These gains or losses,  referred to
under the Code as "section  988" gains or losses,  may  increase or decrease the
amount of a Fund's  investment  company  taxable income to be distributed to its
shareholders.

DISTRIBUTIONS TO FOREIGN SHAREHOLDERS. Dividends paid by a Fund to a shareholder
who, as to the United States,  is a nonresident  alien individual or nonresident
alien  fiduciary  of  a  trust  or  estate,  foreign  corporation,   or  foreign
partnership   ("foreign   shareholder")   generally  will  be  subject  to  U.S.
withholding  tax (at a rate of 30% or, if the  United  States  has an income tax
treaty with the foreign country where the foreign shareholder resides, any lower
treaty rate). An investor claiming to be a foreign  shareholder will be required
to provide a Fund with supporting documentation in order for the Fund to apply a
reduced  withholding  rate or exemption from  withholding.  Withholding will not
apply if a  dividend  paid by a Fund to a foreign  shareholder  is  "effectively
connected  with the  conduct  of a U.S.  trade or  business,"  in which case the
reporting and withholding  requirements applicable to domestic shareholders will
apply.

DERIVATIVES  STRATEGIES.  The use of  derivatives  strategies,  such as  writing
(selling) and purchasing options and futures contracts and entering into forward
contracts,  involves  complex rules that will  determine for income tax purposes
the amount,  character, and timing of recognition of the gains and losses a Fund
realizes  in  connection  therewith.  Gains  from  the  disposition  of  foreign
currencies  (except  certain gains that may be excluded by future  regulations),
and gains from options,  futures,  and forward  contracts derived by a Fund with
respect to its business of investing in securities or foreign  currencies,  will
qualify as permissible income under the Income Requirement.

Certain options (including  options on "broad-based"  stock indices) and futures
in which the Funds may invest will be "section  1256  contracts."  Section  1256
contracts  held by a Fund at the end of each  taxable  year,  other than section
1256  contracts  that are part of a "mixed  straddle"  with respect to which the
Fund has  made an  election  not to have  the  following  rules  apply,  must be
"marked-to-market"  (that is,  treated as sold for their fair market  value) for
Federal  income tax purposes,  with the result that  unrealized  gains or losses
will be treated as though they were  realized.  Sixty percent of any net gain or
loss recognized on these deemed sales,  and 60% of any net realized gain or loss
from any actual  sales of section 1256  contracts,  will be treated as long-term
capital gain or loss, and the balance will be treated as short-term capital gain
or loss. Section 1256 contracts also may be marked-to-market for purposes of the
Excise Tax.

Code  section  1092  (dealing  with  straddles)  may also affect the taxation of
options  and  futures  contracts  in which the Funds may  invest.  Section  1092


                                       28
<PAGE>



defines a "straddle" as offsetting  positions with respect to personal property;
for these purposes, options and futures contracts are personal property. Section
1092  generally  provides that any loss from the  disposition of a position in a
straddle may be deducted only to the extent the loss exceeds the unrealized gain
on the  offsetting  position(s)  of the  straddle.  Section  1092 also  provides
certain "wash sale" rules,  which apply to transactions where a position is sold
at a loss and a new offsetting  position is acquired within a prescribed period,
and  "short  sale"  rules  applicable  to  straddles.  If a Fund  makes  certain
elections, the amount,  character, and timing of recognition of gains and losses
from the affected  straddle  positions would be determined under rules that vary
according  to  the  elections  made.  Because  only  a few  of  the  regulations
implementing the straddle rules have been  promulgated,  the tax consequences to
the Funds of straddle transactions are not entirely clear.

If a call  option  written by a Fund  lapses  (I.E.,  terminates  without  being
exercised),  the  amount of the  premium  it  received  for the  option  will be
short-term  capital gain. If a Fund enters into a closing  purchase  transaction
with respect to a written call option, it will have a short-term capital gain or
loss based on the  difference  between the premium it received for the option it
wrote  and the  premium  it pays for the  option  it buys.  If such an option is
exercised and a Fund thus sells the  securities or futures  contract  subject to
the option, the premium the Fund received will be added to the exercise price to
determine  the gain or loss on the sale.  If a call option  purchased  by a Fund
lapses, it will realize  short-term or long-term capital loss,  depending on its
holding period for the security or futures contract  subject thereto.  If a Fund
exercises a purchased  call  option,  the premium it paid for the option will be
added to the basis of the subject securities or futures contract.

The foregoing is only a general summary of some of the important  Federal income
tax considerations  generally affecting the Funds. No attempt is made to present
a complete  explanation  of the Federal tax treatment of their  activities,  and
this  discussion  is not  intended as a  substitute  for  careful tax  planning.
Accordingly, potential investors are urged to consult their own tax advisers for
more detailed  information  and for  information  regarding any state,  local or
foreign taxes  applicable to the Funds and to dividends and other  distributions
therefrom.

                                         Notes to the Financial Statement
                                                 September 2, 1997



 1.      Organization
         ------------
 
         Potomac Funds (the "Trust") was organized as a  Massachusetts  Business
         Trust on June 6, 1997 and is registered  under the  Investment  Company
         Act of 1940,  as amended  (the "1940 Act"),  as an open-end  management
         investment   company   issuing  its  shares  in  series,   each  series
         representing a distinct  portfolio  with its own investment  objectives
         and policies.  The series presently authorized are the Japan/Long Fund,
         Japan/Short  Fund,  U.S.  Plus Fund,  U.S./Short  Fund,  OTC Plus Fund,
         OTC/Short Fund and the U.S. Government Money Market Fund (collectively,
         the "Funds").  Each Fund (other than the U.S.  Government  Money Market
         Fund) is a  "non-diversified"  series of the Trust pursuant to the 1940
         Act.  The Funds have had no  operations  other than those  relating  to
         organizational matters, including the sale of one share for cash in the
         amount of $10 of each of the Japan/Long  Fund,  Japan/Short  Fund, U.S.
         Plus Fund,  U.S./Short  Fund, OTC Plus Fund,  OTC/Short Fund and 99,940
         shares for cash in the amount of $99,940 of the U.S.  Government  Money
         Market Fund to capitalize the Funds,  which were sold to Rafferty Asset
         Management LLC (the "Adviser") on September 2, 1997.

2.      Significant Accounting Policies
        -------------------------------

        (a)    Organization Costs
               ------------------

               Costs incurred by the Trust in connection with the  organization,
               registration and the initial public offering of shares, are being
               deferred  and  amortized  over the period of benefit,  but not to
               exceed sixty months from the Trust's  commencement of operations.
               These costs were  advanced by the Adviser and will be  reimbursed
               by the Trust.  The  proceeds  of any  redemption  of the  initial
               shares by the original  shareholder will be reduced by a pro-rata
               portion of any then  unamortized  organizational  expenses in the
               same  proportion as the number of initial  shares being  redeemed
               bears to the number of initial shares  outstanding at the time of
               such redemption.

        (b)    Federal Income Taxes
               --------------------

               Each Fund intends to comply with the requirements of the Internal
               Revenue  Code  necessary  to  qualify as a  regulated  investment
               company  and to make the  requisite  distributions  of income and
               capital gains to their shareholders sufficient to relieve it from
               all or substantially all Federal income taxes.

 3.      Investment Adviser
         ------------------

         The Trust has an agreement with the Adviser, with whom certain officers
         and  Trustees  of the  Trust  are  affiliated,  to  furnish  investment

<PAGE>

         advisory services to the Funds. Under the terms of this agreement,  the
         Adviser  will receive the  following  percentage  of average  daily net
         assets  for each Fund:  0.75% for the  Japan/Long  Fund,  0.90% for the
         Japan/Short  Fund,  0.75%  for  the  U.S.  Plus  Fund,  0.90%  for  the

 4.      Service and Distribution Plan
         -----------------------------

         Pursuant  to Rule 12b-1  under the 1940 Act,  the Funds have  adopted a
         Service and Distribution Plan (the "Plan"). The Plan provides that each
         Fund will compensate the distributor for certain  expenses  incurred in
         the   distribution   of  that  Fund's  shares  and  the  servicing  and
         maintenance  of existing  Fund  shareholder  accounts.  Pursuant to the
         Plan, a Fund may pay the distributor a service fee of up to 0.25% and a
         distribution fee of up to 0.75% of the Fund's average daily net assets.
         However,  the Plan will not be  activated  until such time as the Trust
         obtains Trustee approval.

To the Shareholder and Board of Trustees of
  Potomac Funds

In our opinion,  the accompanying  statement of assets and liabilities  presents
fairly,  in all  material  respects,  the  financial  position  of  each  of the
portfolios  of Potomac  funds (the "Fund") at September 2, 1997,  in  conformity
with generally accepted accounting  principles.  This financial statement is the
responsibility  of the Fund's  management;  our  responsibility is to express an
opinion on this financial statement based on our audits. We conducted our audits
of this  financial  statement in accordance  with  generally  accepted  auditing
standards which require that we plan and perform the audit to obtain  reasonable
assurance   about   whether  the   financial   statement  is  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement  presentation.  We believe that our audits provide a
reasonable basis for the opinion expressed above.
