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 
                              Index[TRADEMARK]
 Potomac OTC/Short Fund       Inverse (opposite) of the Nasdaq 100 
                              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.  THIS FUND SEEKS TO
MAINTAIN A CONSTANT  $1.00 NET ASSET  VALUE PER SHARE,  ALTHOUGH  THIS CANNOT BE
ASSURED.

<PAGE>


   
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.

                               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.
    

                                       4

<PAGE>



   
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.
    
   
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  Index[TRADEMARK]  (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.
    

                                       5

<PAGE>



   
The POTOMAC OTC PLUS FUND ("OTC Plus Fund") seeks to provide  investment returns
that  correspond to 125% of the  performance of the Nasdaq 100  Index[TRADEMARK]
("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.
    
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  characteristics  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.

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.

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

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.

                                       10

<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
variation margin, as "cover" for the investment  techniques it employs,  as part
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.
   
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 price 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

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,  involve  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.

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.

                                       14

<PAGE>


   
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.

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.
   
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
option 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).
   
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 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.

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.

                                       18

<PAGE>


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.
    
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.

                                       19

<PAGE>



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.
   
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.

                                       20

<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 cash
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.
    

                             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.

                         TAX-SHELTERED RETIREMENT PLANS
   
The  Trust  offers  the  following  retirement  plans  that may be  funded  with
purchases  of Fund  shares and may allow  investors  to shelter or defer some of
their income from taxes:
    
   
      Individual retirement accounts ("IRAs"),
      Self-employed  individual  retirement  plans  ("Keogh  Plans")  -  defined
      contribution plans, and Code section 403(b) plans.
    
   
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.
    
   
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 a 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.
    

                                       23

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.
    

                           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 701 Milwaukee,  Wisconsin
53201.  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  Funds 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

                                       24


<PAGE>



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 markets changes. If such conditions
occur, redemption or exchange orders can be made by mail.
    

                        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,
fifteen  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,  fifteen  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.

                                       25

<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.
    

                        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

                                       26

<PAGE>



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 RIC. 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.

                                       27

<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.
    
   
If Fund  shares are  redeemed at a loss after being held for six months or less,
the loss is treated as  long-term,  instead of  short-term,  capital loss to the
extent of any capital gain distributions on those shares.
    
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 backup
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.

distribution of Fund shares, and otherwise currently pays all distribution costs
for Fund shares. 
   
Under  an  investment  agreement  between  the  Trust  and  the  Adviser,  dated
September,  1997, 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 and U.S.  Government  Bond Funds.  The Rydex OTC Fund,
which seeks to match the performance of the Nasdaq Index, has similar investment
objective and policies as the OTC Plus Fund. At May 15, 1997, that fund had $___
million in assets.  As  portfolio  manager of the Rydex OTC Fund,  Mr. Apple had
full  discretionary  authority over the selection of investments  for that fund.
Average annual total returns for the one-year and  three-year  periods ended May
15, 1997 during which Mr. Apple managed that fund compared with the  performance
of the Nasdaq Index were:

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 net
assets,  and .03% of the Trust's  average net assets in excess of  $500,000,000.
Notwithstanding  the  foregoing,  the  Administrator's  minimum  annual  fee  is
$170,000.

                       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.

                                       30

<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  the
securities of a limited number of issuers, primarily within same the 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.

<PAGE>


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.

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 than 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:

Potomac OTC/Short Fund        Inverse (opposite) of the Nasdaq 100 Stock IndexTM

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.

                                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


                                       3
<PAGE>




Futures  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.



                                       5
<PAGE>




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  as 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  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
market),  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 by 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.


                                       8
<PAGE>




Secondary  markets generally do not exist for forward currency  contracts,  with
the result that closing transactions  generally can be made for forward currency
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.

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  in  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
with borrowed funds is not  sufficient to cover the cost of leveraging,  the net


                                       11
<PAGE>




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 instrument 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
the fees and expenses paid by shareholders of the other investment  company,  in


                                       12
<PAGE>




    
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 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


                                       13
<PAGE>




Funds. A Fund may have to dispose of certain  portfolio  investments to maintain
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

   liabilities and indebtedness not constituting senior securities),  except (1)
   that the Fund may issue senior  securities in connection with transactions in

   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 sale

   exceed 5% of the value of the Fund's total assets,  (3) to enter into reverse

FOLLOWING INVESTMENT LIMITATION:

A Fund shall not:

10.Invest more than 25% of the value of its total  assets in the  securities  of

                                       16

5. Issue  senior  securities,  except  as  permitted  by the  Fund's  investment

   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

   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
brokers-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


                                       17
<PAGE>




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;
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.
    
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,  dated September __, 1997, 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


                                       20
<PAGE>




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,  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 by (2) 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.

DISTRIBUTOR
   
First Data  Distributors,  Inc.,  4400 Computer Drive,  Westboro,  Massachusetts
01581, serves as the distributor ("Distributor") in connection with the offering
of each Fund's  shares on a no-load  basis.  The  Distributor  receives from the
Adviser a minimum  fee of  $10,000  plus  .01% of the  first $1  billion  of the
Trust's average daily net assets and out-of-pocket expenses for distributing the
shares of the Funds.
    
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 on 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


                                       22
<PAGE>




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
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  deigned 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.



                                       23
<PAGE>




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"),  Nasdaq 100 Stock
IndexTM ("Nasdaq Index"), and the Nasdaq Composite IndexTM ("Nasdaq Composite"),
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  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)n(SUPERSCRIPT)=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


                                       24
<PAGE>




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.

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 pre-existing 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  pre-existing  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,


                                       25
<PAGE>




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 on 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


                                       26
<PAGE>




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
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


                                       27
<PAGE>




- --- 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
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


                                       28
<PAGE>




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) also may also affect the taxation of
options  and  futures  contracts  in which the Funds may  invest.  Section  1092
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
         advisory services to the Funds. Under the terms of this agreement,  the

<PAGE>




         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
         U.S./Short  Fund,  0.75% for the OTC Plus Fund, 0.90% for the OTC/Short
         Fund and 0.50% for the U.S.
         Government Money Market Fund.

 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.

         Article XI,  Section 2 of the  Trust's  Declaration  of Trust  provides
that:

         (a) Subject to the  exceptions and  limitations  contained in paragraph
(b) below:

                  (i) every  person who is, or has been, a Trustee or officer of
the Trust  (hereinafter  referred to as a "Covered Person") shall be indemnified
by the Trust and/or by the appropriate Series to the fullest extent permitted by
law against  liability and against all expenses  reasonably  incurred or paid by
him or her in connection with any claim,  action, suit or proceeding in which he
or she becomes involved as a party or otherwise by virtue of his or her being or
having been a Covered Person and against  amounts paid or incurred by him or her
in the settlement thereof;

                  (ii) the words  "claim,"  "action,"  "suit,"  or  "proceeding"
shall apply to all claims,  actions,  suits or proceedings  (civil,  criminal or
other,  including  appeals),  actual or threatened  while a Covered Person is in
office or thereafter,  and the words  "liability" and "expenses"  shall include,
without  limitation,   attorneys'  fees,  costs,  judgments,   amounts  paid  in
settlement, fines, penalties and other liabilities.



                                      C-2
<PAGE>

        (b)  No indemnification shall be provided hereunder to a Covered Person:

                  (i) who shall have been  adjudicated by a court or body before
which  the  proceeding  was  brought  (A)  to be  liable  to  the  Trust  or its
Shareholders by reason of willful  misfeasance,  bad faith,  gross negligence or
reckless disregard of the duties involved in the conduct of his or her office or
(B) not to have acted in good  faith in the  reasonable  belief  that his or her
action was in the best interest of the Trust; or

                  (ii) in the  event of a  settlement,  unless  there has been a
determination  that such Covered  Person did not engage in willful  misfeasance,
bad faith,  gross negligence or reckless disregard of the duties involved in the
conduct  of his or her  office,  (A) by the court or other  body  approving  the
settlement;  (B) by at  least a  majority  of  those  Trustees  who are  neither
Interested Persons of the Trust nor parties to the matter based upon a review of
readily  available  facts  (as  opposed  to a full  trial-type  inquiry  or full
investigation);  or (C) by written  opinion of  independent  legal counsel based
upon a review of  readily  available  facts  (as  opposed  to a full  trial-type
inquiry);  provided,  however,  that any Shareholder  may, by appropriate  legal
proceedings, challenge any such determination by the Trustees, or by independent
legal counsel.

         (c) The  rights  of  indemnification  herein  provided  may be  insured
against by policies  maintained by the Trust,  shall be severable,  shall not be
exclusive of or affect any other  rights to which any Covered  Person may now or
hereafter be entitled,  shall  continue as to a person who has ceased to be such
Trustee or officer and shall inure to the  benefit of the heirs,  executors  and
administrators  of such a person.  Nothing  contained  herein  shall  affect any
rights to  indemnification  to which Trust  personnel,  other than  Trustees and
officers, and other persons may be entitled by contract or otherwise under law.

         (d) Expenses in connection with the  preparation and  presentation of a
defense to any claim,  action,  suit or proceeding of the character described in
paragraph (a) of this Section 2 may be paid by the Trust from time to time prior
to final  disposition  thereof upon receipt of an undertaking by or on behalf of
such  Covered  Person  that such  amount  will be paid over by him or her to the
Trust  if it is  ultimately  determined  that  he or  she  is  not  entitled  to
indemnification under this Section 2; provided, however, that:

                  (i)  such  Covered  Person  shall  have  provided  appropriate
security for such undertaking,

                  (ii) the Trust is insured  against  losses  arising out of any
such advance payments, or

                  (iii)  either  a  majority  of the  Trustees  who are  neither
interested  persons of the Trust nor parties to the matter, or independent legal
counsel  in a written  opinion,  shall have  determined,  based upon a review of
readily   available   facts  (as  opposed  to  a  trial-type   inquiry  or  full
investigation), that there is reason to believe that such Covered Person will be
found entitled to indemnification under this Section 2.

         According to Article XII,  Section 1 of the  Declaration of Trust,  the
Trust is a trust and not a  partnership.  Trustees are not liable  personally to
any person extending credit to, contracting with or having any claim against the
Trust a particular Series or the Trustees. A Trustee,  however, is not protected
from  liability  due to willful  misfeasance,  bad faith,  gross  negligence  or
reckless disregard of the duties involved in the conduct of his office.

                                      C-3

         Article XII,  Section 2 provides  that,  subject to the  provisions  of
Section 1 of Article  XII and to Article  XI,  the  Trustees  are not liable for
errors of  judgment  or  mistakes  of fact or law, or for any act or omission in
accordance with advice of counsel or other experts or for failing to follow such
advice.

Item 32.          Undertakings
- --------          ------------

         Registrant hereby undertakes to file a Post-effective  Amendment to the
Registration  Statement,  containing  financial  statements  that  need  not  be
certified,   within  four  to  six  months  from  the  effective  date  of  this
Registration Statement or from the date of its commencement of operations.

         Registrant   hereby  undertakes  to  furnish  each  person  to  whom  a
prospectus is delivered with a copy of its latest annual report to Shareholders,
upon request and without charge.

         Registrant   hereby   undertakes  to  carry  out  all   indemnification
provisions of its Declaration of Trust in accordance with Investment Company Act
Release  No.  11330  (September  4,  1980) and  successor  releases.  Insofar as
indemnification  for  liability  arising  under the  Securities  Act of 1933, as
amended  ("1933 Act"),  may be permitted to trustees,  officers and  controlling
persons of the Registrant pursuant to the provisions in under Item 27 herein, or
otherwise,  the  Registrant has been advised that in the opinion of the SEC such
indemnification  is against  public  policy as expressed in the 1933 Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such liabilities  (other than the payment by the Registrant of expenses incurred
or paid by a trustee,  officer or  controlling  person of the  Registrant in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
trustee,  officer or controlling  person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy  as  expressed  in the  1933  Act  and  will  be  governed  by the  final
adjudication.

                                  POTOMAC FUNDS
                          INVESTMENT ADVISORY AGREEMENT


      This  Investment  Advisory  Agreement  is made as of  September  __, 1997,
between the Potomac Funds (the "Trust"),  a business trust  organized  under the
laws of the Commonwealth of  Massachusetts  with its principal place of business
at  550  Mamaroneck  Avenue,  Harrison,  New  York  10528,  and  Rafferty  Asset
Management, LLC, a New York limited liability corporation (the "Adviser").

      WHEREAS, the Trust is registered under the Investment Company Act of 1940,
as amended (the "Act"), as an open-end management  investment company consisting
of one or more  investment  series of  shares,  each  having  its own assets and
investment policies;

      WHEREAS, the Adviser provides investment advice and is registered with the
Securities and Exchange  Commission  (the "SEC") as an investment  adviser under
the Investment Advisers Act of 1940, as amended (the "Advisers Act"); and

      WHEREAS,  the Trust  desires to retain the  Adviser to perform  investment
advisory  services for each series of the Trust listed in one or more  Schedules
attached hereto (collectively,  the "Portfolios"), and the Adviser is willing to
perform such services on the terms and conditions set forth in this Agreement;

      NOW,  THEREFORE,  in  consideration  of the premises and mutual  covenants
herein contained, it is agreed between the parties hereto as follows:

      1.  APPOINTMENT.  The Trust hereby  appoints  the Adviser,  subject to the
direction and control of the Trust's Board of Trustees (the "Board"),  to manage
the  investment  and  reinvestment  of the  assets of each  Portfolio  listed on
Schedule A of this Agreement (as such schedule may be amended from time to time)
for the period and on the terms set forth in this Agreement. The Adviser accepts
such  appointment  and  agrees to render the  services  herein set forth for the
compensation as set forth on Schedule A. In the  performance of its duties,  the
Adviser will act in the best  interests of the Trust and each Portfolio and will
comply with (a) applicable laws and regulations,  including, but not limited to,
the 1940 Act, (b) the terms of this  Agreement,  (c) the Trust's  Declaration of
Trust,  By-Laws  and  currently  effective   registration  statement  under  the
Securities  Act of 1933,  as  amended,  and the  1940  Act,  and any  amendments
thereto, (d) the stated investment objective,  policies and restrictions of each
applicable Portfolio,  and (e) such other guidelines as the Board reasonably may
establish.

<PAGE>



      2.  DUTIES AS INVESTMENT ADVISER.

          (a) Subject to the supervision of the Board,  the Adviser will provide
a  continuous  investment  program  for  each  Portfolio,  including  investment
research and management  with respect to all  securities,  investments  and cash
equivalents in each Portfolio. The Adviser will determine from time to time what
securities  and other  investments  will be purchased,  retained or sold by each
Portfolio.  To carry out such  decisions,  the Adviser hereby is authorized,  as
agent and attorney-in-fact for the Trust, for the account of, at the risk of and
in the name of the Trust, to place orders and issue instructions with respect to
those transactions of the Portfolios.  The Adviser will exercise full discretion
and act for each Portfolio in the same manner and with the same force and effect
as such Portfolio itself might or could do with respect to purchases,  sales, or
other  transactions,  as well as with respect to all other  things  necessary or
incidental  to the  furtherance  or  conduct of such  purchases,  sales or other
transactions.

      (b)  The  Adviser   will  place   orders   pursuant   to  its   investment
determinations  for each  Portfolio  either  directly with the issuer or through
other  brokers.  In the selection of brokers and the placement of orders for the
purchase and sale of portfolio investments for the Portfolios, the Adviser shall
use its best efforts to obtain for the Portfolios  the most favorable  price and
execution  available,  except to the  extent it may be  permitted  to pay higher
brokerage commissions for brokerage and research services as described below. In
using  its best  efforts  to  obtain  the most  favorable  price  and  execution
available, the Adviser, bearing in mind the Trust's best interests at all times,
shall consider all factors it deems relevant,  including by way of illustration,
price, the size of the  transaction,  the nature of the market for the security,
the amount of the commission,  the timing of the transaction taking into account
market prices and trends, the reputation,  experience and financial stability of
the broker  involved and the quality of service  rendered by the broker in other
transactions.  Subject to such policies as the Board may determine,  the Adviser
shall  not be deemed  to have  acted  unlawfully  or to have  breached  any duty
created by this  Agreement or otherwise  solely by reason of its having caused a
Portfolio to pay a broker that provides  brokerage and research  services to the
Adviser an amount of commission for effecting a portfolio investment transaction
in excess of the amount of  commission  another  broker  would have  charged for
effecting  that  transaction  if the Adviser  determines in good faith that such
amount of  commission  was  reasonable in relation to the value of the brokerage
and research  services  provided by such broker,  viewed in terms of either that
particular transaction or the Adviser's overall responsibilities with respect to
the Trust and to other clients of the Adviser as to which the Adviser  exercises
investment discretion. In no instance will portfolio securities of any Portfolio
be  purchased  from or sold  to the  Adviser  or any  affiliated  person  of the
Adviser.  The Trust agrees that any entity or person associated with the Adviser
that is a member of a national  securities  exchange is authorized to effect any
transaction  on such exchange for the account of the Trust which is permitted by
Section 11(a) of the Securities Exchange Act of 1934, as amended,  and the rules
thereunder,  and the Trust has  consented to the retention of  compensation  for
such transactions.

                                      -2-

<PAGE>



      (c) The  Adviser  will  report to the Board at each  meeting  thereof  all
changes in the Portfolios  since the prior report,  and also will keep the Board
informed of  important  developments  affecting  the Trust,  Portfolios  and the
Adviser,  and on its own  initiative,  will  provide the Board from time to time
such  information  as the  Adviser  may believe  appropriate  for this  purpose,
whether  concerning the individual  companies whose securities are included in a
Portfolio's  holdings,  the  industries  in which they engage,  or the economic,
social or political conditions prevailing in each country in which the Portfolio
maintains investments. The Adviser also make available to the Board upon request
any  economic,   statistical  and  investment  services  normally  available  to
institutional or other customers of the Adviser.

      (d) The  Adviser  will from time to time  employ  or  associate  with such

acknowledged as otherwise payable by the Adviser pursuant to this Agreement, the
Trust may reduce the fee payable to the Adviser  pursuant to  paragraph 7 hereof
by such amount. To the extent that such deductions exceed the fee payable to the

deducted in the same manner from the fee payable on succeeding  monthly  payment
dates.

Trust or any  Portfolio in connection  with the matters to which this  Agreement
relate except a loss resulting from the willful misfeasance,  bad faith or gross
negligence  on its  part in the  performance  of its  duties  or  from  reckless
disregard by it of its obligations and duties under this Agreement.  Any person,
even though also an officer, partner, employee, or agent of the Adviser, who may
be or become  an  officer,  trustee,  employee  or agent of the  Trust  shall be
deemed,  when  rendering  services to the Trust or acting in any business of the
Trust,  to be rendering  such services to or acting solely for the Trust and not

changes in annual  rates or the  addition or  deletion  of a Portfolio  from the

Portfolio before the end of any month, the fee for the period from the effective
date to the end of the month or from the  beginning of such month to the date of
termination,  as the case may be, shall be prorated  according to the proportion
that  such  period  bears to the  full  month in  which  such  effectiveness  or
termination occurs.

      8. DURATION AND  TERMINATION.  This Agreement shall become  effective upon
its  execution;  provided,  that with respect to any  Portfolio  now existing or

subadviser, by vote cast in person at a meeting called for the purpose of voting

annually  after  the  initial  two-year   period,   then  this  Agreement  shall
automatically  terminate at the close of business on the second  anniversary  of
its execution, or upon the expiration of one year from the effective date of the
last such  continuance,  whichever  is  later;  provided,  however,  that if the
continuance  of this Agreement is submitted to the  shareholders  of a Portfolio
for their  approval and such  shareholders  fail to approve such  continuance of
this Agreement as provided  herein,  the Adviser may continue to serve hereunder
in a  manner  consistent  with  the  1940  Act and  the  rules  and  regulations
thereunder with respect to that Portfolio; or

      (c) The Adviser may at any time  terminate  this Agreement with respect to
any or all  Portfolios  by not less than 60 days'  written  notice  delivered or
mailed by registered mail, postage prepaid to the Trust.

      (d)   This Agreement  automatically  and  immediately  will terminate in
the event of its assignment.

changed,  waived,  discharged or terminated  orally,  except by an instrument in
writing  signed by the party against which  enforcement  of the change,  waiver,
discharge or termination is sought. No material amendment of this Agreement with
respect to any Portfolio shall be effective  except, if required by law, by vote
of the holders of a majority of that Portfolio's outstanding voting securities.

conflict  with the  applicable  provisions  of the 1940 Act,  the  latter  shall
control.

invalid by a court decision,  statute, rule or otherwise,  the remainder of this
Agreement  shall not be affected  thereby.  This Agreement shall be binding upon

            In the event of a mechanical  breakdown or failure of  communication
      or power supplies beyond its control,  FTC shall take all reasonable steps
      to minimize service  interruptions  for any period that such  interruption
      continues beyond FTC's control.  FTC will make every reasonable  effort to
      restore any lost or damaged  data and correct  any errors  resulting  from
      such a breakdown at the expense of FTC.  FTC agrees that it shall,  at all
      times, have reasonable contingency plans with appropriate parties,  making
      reasonable  provision  for emergency  use of  electrical  data  processing

                                      -4-

      equipment   to   the   extent   appropriate    equipment   is   available.
      Representatives  of the Fund shall be entitled to inspect  FTC's  premises
      and operating  capabilities  at any time during regular  business hours of
      FTC, upon reasonable notice to FTC.

            Regardless  of the above,  FTC reserves  the right to reprocess  and
      correct administrative errors at its own expense.

            B. In order that the  indemnification  provisions  contained in this
      section shall apply,  it is understood  that in any case in which the Fund
      may be asked to  indemnify or hold FTC  harmless,  the Fund shall be fully
      and promptly  advised of all pertinent  facts  concerning the situation in
      question,  and it is further  understood  that FTC will use all reasonable
      care to notify the Fund promptly  concerning any situation  which presents
      or  appears  likely  to  present  the  probability  of  such a  claim  for
      indemnification against the Fund. The Fund shall have the option to defend
      FTC against any claim which may be the subject of this indemnification. In
      the event that the Fund so elects, it will so notify FTC and thereupon the
      Fund shall take over complete  defense of the claim, and FTC shall in such
      situation  initiate no further legal or other  expenses for which it shall
      seek indemnification  under this section. FTC shall in no case confess any
      claim or make any  compromise  in any case in which the Fund will be asked
      to indemnify FTC except with the Fund's prior written consent.

            C. FTC shall  indemnify  and hold the Fund harmless from and against
      any and all claims,  demands,  losses,  expenses, and liabilities (whether
      with or without  basis in fact or law) of any and every nature  (including
      reasonable  attorneys'  fees) which the Fund may sustain or incur or which
      may  be  asserted  against  the  Fund  by  any  person  arising  out of or
      attributed  to any action  taken or omitted to be taken by FTC as a result
      of FTC's refusal or failure to comply with the terms of this Agreement, or
      from its bad faith, negligence, or willful misconduct of FTC or any of its
      employees and agents.

VI.   Confidentiality

      FTC  agrees  on behalf of itself  and its  employees  and  agents to treat
      confidentially  all  information  relating to the Fund's business which is
      received by FTC during the course of rendering any service hereunder.  FTC
      agrees  on  behalf  of  itself  and its  employees  and  agents  to  treat
      confidentially all records and other information  relative to the Fund and
      its shareholders  and shall not disclose to any other party,  except after
      prior  notification to and approval in writing by the Fund, which approval
      shall not be  unreasonably  withheld and may not be withheld where FTC may
      be exposed to civil or criminal contempt proceedings for failure to comply
      after being  requested to divulge  such  information  by duly  constituted
      authorities.

VII.  Data Necessary to Perform Service

      The Fund or its  agent,  which may be FTC,  shall  furnish to FTC the data
      necessary  to perform the services  described  herein at times and in such
      form as mutually agreed upon.

VIII. Terms of Agreement

      This  Agreement  shall become  effective  upon its execution  and,  unless
      sooner  terminated  as  provided  herein,   shall  remain  in  effect  for
      successive annual periods. The Agreement may be terminated by either party
      upon giving ninety (90) days' prior  written  notice to the other party or
      such shorter period as is mutually  agreed upon in writing by the parties.
      This Agreement will  automatically and immediately  terminate in the event
      of its assignment.  Termination of this Agreement pursuant to this Section
      VIII shall be without the payment of any penalty.

IX.   Duties in the Event of Termination

      In the event that, in connection with  termination,  a successor to any of
      FTC's duties or  responsibilities  hereunder is  designated by the Fund by
      written notice to FTC, FTC will promptly, upon such termination and at the
      expense  of the Fund,  transfer  to such  successor  all  relevant  books,
      records,  correspondence,  and other data established or maintained by FTC
      under this Agreement in a form reasonably  acceptable to the Fund (if such
      form differs from the form in which FTC has maintained  such records,  the
      Fund shall pay any expenses  associated with transferring the data to such
      form),   and  will   cooperate   in  the   transfer  of  such  duties  and
      responsibilities,  including provision for assistance from FTC's personnel
      in the establishment of books, records, and other data by such successor.

X.    Choice of Law

      This Agreement shall be construed in accordance with the laws of the State
      of  Wisconsin.  Trustees  and  shareholders  of  the  Fund  shall  not  be
      personally  liable for the  obligations of the Fund in connection with any
      matter arising from or in connection with this Agreement.

XI.   Notices

      Notices of any kind to be given by either  party to the other  party shall
      be in writing and shall be duly given if mailed or  delivered  as follows:
      notice to FTC shall be sent to Mutual  Fund  Services  located at 615 East
      Michigan Street,  Milwaukee,  Wisconsin 53202 and notice to the Fund shall
      be sent to the Potomac Funds located at 550 Mamaroneck  Avenue,  Harrison,
      NY 10528.

XII.  Records

      FTC shall keep records relating to the services to be performed hereunder,
      in the form and manner,  and for such period as it may deem  advisable and
      is  acceptable  to the  Fund  but not  inconsistent  with  the  rules  and
      regulations of appropriate government authorities, in particular,  Section
      31 of the 1940 Act,  and the rules  thereunder.  FTC agrees  that all such
      records  prepared or  maintained  by FTC  relating  to the  services to be
      performed  by FTC  hereunder  are the  property  of the  Fund  and will be
      preserved,  maintained,  and made available with such section and rules of
      the  1940  Act and  will be  promptly  surrendered  to the  Fund on and in
      accordance with its request.

                             DISTRIBUTION AGREEMENT


      THIS  AGREEMENT  is made as of this _____ day of  ____________,  1997 (the
"Agreement")  by and between The Potomac Funds, a  ______________business  trust
(the  "Company")  and First  Data  Distributors,  Inc.  (the  "Distributor"),  a
Massachusetts corporation.

      WHEREAS,  the Company is registered as a diversified,  open-end management
investment  company  under the  Investment  Company Act of 1940, as amended (the
"1940 Act"); and is currently offering units of beneficial  interest (such units
of all series are hereinafter  called the "Shares"),  representing  interests in
investment  portfolios  of the  Company  identified  on  Schedule A hereto  (the
"Funds") which are registered  with the Securities and Exchange  Commission (the
"SEC")  pursuant  to the  Company's  Registration  Statement  on Form  N-1A (the
"Registration Statement"); and

      WHEREAS,  the Company desires to retain the Distributor as distributor for
the Funds to provide  for the sale and  distribution  of the Shares of the Funds
identified  on  Schedule  A and for such  additional  classes  or  series as the
Company may issue,  and the  Distributor  is prepared to provide  such  services
commencing on the date first written above.

      NOW THEREFORE,  in  consideration of the premises and mutual covenants set
forth herein and intending to be legally  bound hereby the parties  hereto agree
as follows:

1.    SERVICE AS DISTRIBUTOR

1.1.    The Distributor  will act on behalf of the Company for the  distribution
        of the Shares covered by the Registration Statement under the Securities
        Act of 1933, as amended (the "1933 Act").  The Distributor  will have no
        liability  for payment for the purchase of Shares sold  pursuant to this
        Agreement or with respect to redemptions or repurchases of Shares.

1.2.    The  Distributor  agrees  to  use  efforts  deemed  appropriate  by  the
        Distributor  to  solicit  orders  for the  sale of the  Shares  and will
        undertake such  advertising  and promotion as it believes  reasonable in
        connection with such  solicitation;  provided,  however,  that each Fund
        will bear the expenses  incurred and other  payments  made in accordance
        with the  provisions  of the  Agreement  and any  plan now or  hereafter
        adopted with  respect to any Fund  pursuant to Rule 12b-1 under the 1940
        Act  (the  "Plans").   To  the  extent  that  the  Distributor  receives
        shareholder services fees under any shareholder services plan adopted by
        the  Company,  the  Distributor  agrees to  furnish,  and/or  enter into
        arrangements  with others for the furnishing of, personal and/or account
        maintenance  services with respect to the relevant  shareholders  of the
        Company as may be  required  pursuant to such plan.  It is  contemplated
        that the Distributor will enter into sales or servicing  agreements with
        securities   dealers,   financial   institutions   and  other   industry
        professionals,  such as  investment  advisers,  accountants  and  estate
        planning firms.

1.3.    The Company  understands  that the  Distributor  is now,  and may in the
        future be, the distributor of the shares of several investment companies
        or  series   (collectively,   the  "Investment   Entities"),   including
        Investment Entities having investment objectives similar to those of the
        Company.  The Company further  understands  that investors and potential
        investors  in the Company may invest in shares of such other  Investment
        Entities.  The  Company  agrees  that the  Distributor's  duties to such
        Investment  Entities  shall not be deemed in conflict with its duties to
        the Company under this Section 1.3.

1.4.    The  Distributor  shall not utilize any materials in connection with the
        sale or offering of Shares except the Company's prospectus and statement
        of additional  information and such other materials as the Company shall
        provide or approve.

1.5.    All activities by the Distributor  and its employees,  as distributor of
        the  Shares,   shall  comply  with  all  applicable   laws,   rules  and
        regulations,  including,  without limitation,  all rules and regulations
        made or adopted by the SEC or the  National  Association  of  Securities
        Dealers.

1.6.    The Distributor  will transmit any orders received by it for purchase or
        redemption of the shares to the transfer agent for the Company

1.7.    Whenever in its judgment  such action is  warranted  by unusual  market,
        economic or political conditions or abnormal  circumstances of any kind,
        the  Company may decline to accept any orders for, or make any sales of,
        the Shares  until such time as the Company  deems it advisable to accept
        such  orders  and to make  such  sales,  and  the  Company  advises  the
        Distributor promptly of such determination.

1.8.    The Distributor may enter into selling  agreements with selected dealers
        or other  institutions  with  respect to the  offering  of Shares to the
        public.  Each such selling  agreement will provide (a) that all payments
        for  purchases of Shares will be sent  directly  from the dealer or such
        other  institution to the Funds' transfer agent and (b) that, if payment
        is not made with  respect to  purchases  of Shares at the  customary  or
        required time for settlement of the  transaction,  the Distributor  will
        have the right to cancel the sale of the Shares ordered by the dealer or
        such  other  institution,  in  which  case  the  dealer  or  such  other
        institution will be responsible for any loss suffered by any Fund or the
        Distributor  resulting from such cancellation.  The Distributor may also
        act as  disclosed  agent  for a Fund and  sell  Shares  of that  Fund to
        individual  investors,  such transactions to be specifically approved by
        an officer of that Fund.

                                       2

1.9.    The Company agrees to pay all costs and expenses in connection  with the
        registration of Shares under the Securities Act of 1933, as amended, and
        all expenses in connection with maintaining facilities for the issue and
        transfer of Shares and for supplying information,  prices and other data
        to be furnished by the Fund  hereunder,  and all expenses in  connection
        with  the  preparation  and  printing  of the  Fund's  prospectuses  and
        statements of additional  information  for  regulatory  purposes and for
        distribution to shareholders.

1.10.   The Company  agrees at its own expense to execute any and all  documents
        and to furnish any and all information and otherwise to take all actions
        that may be reasonably necessary in connection with the qualification of
        the Shares for sale in such states as the Distributor may designate. The
        Company shall notify the  Distributor  in writing of the states in which
        the Shares may be sold and shall  notify the  Distributor  in writing of
        any changes to the information contained in the previous notification.

1.11.   The Company shall furnish from time to time, for use in connection  with
        the sale of the Shares, such information with respect to the Company and
        the Shares as the  Distributor may reasonably  request;  and the Company
        warrants that the  statements  contained in any such  information  shall
        fairly show or  represent  what they purport to show or  represent.  The
        Company  shall also  furnish the  Distributor  upon  request  with:  (a)
        audited  annual  statements  and unaudited  semi-annual  statements of a
        Fund's  books  and  accounts  prepared  by the  Company,  (b)  quarterly
        earnings statements prepared by the Company, (c) a monthly itemized list
        of the  securities in the Funds,  (d) monthly  balance sheets as soon as
        practicable  after the end of each month, and (e) from time to time such
        additional  information regarding the financial condition of the Company
        as the Distributor may reasonably request.

1.12.   The  Company   represents  to  the  Distributor  that  all  Registration
        Statements and prospectuses  filed by the Company with the SEC under the
        1933 Act with  respect to the Shares have been  prepared  in  conformity
        with the  requirements  of the 1933 Act and the rules and regulations of
        the SEC thereunder.  As used in this Agreement,  the term  "Registration
        Statement" shall mean any Registration  Statement and any prospectus and
        any  statement of additional  information  relating to the Company filed
        with the SEC and any amendments or supplements thereto at any time filed
        with the SEC.  Except as to  information  included  in the  Registration
        Statement in reliance  upon  information  provided to the Company by the
        Distributor or any affiliate of the Distributor expressly for use in the
        Registration  Statement,  the  Company  represents  and  warrants to the
        Distributor  that any  Registration  Statement,  when such  Registration
        Statement  becomes  effective,  will contain  statements  required to be
        stated  therein  in  conformity  with  the 1933  Act and the  rules  and
        regulations  of the SEC; that all  statements  of fact  contained in any
        such  Registration   Statement  will  be  true  and  correct  when  such
        Registration  Statement  becomes  effective;  and  that no  Registration
        Statement  when  such  Registration  Statement  becomes  effective  will


                                       3

        include  an  untrue  statement  of a  material  fact or omit to  state a
        material  fact  required to be stated  therein or  necessary to make the
        statements  therein not  misleading  to a purchaser  of the Shares.  The
        Company may but shall not be obligated to propose from time to time such
        amendment  or  amendments  to  any   Registration   Statement  and  such
        supplement or  supplements  to any prospectus as, in the light of future
        developments, may, in the opinion of the Company's counsel, be necessary
        or advisable.  The Company shall promptly  notify the Distributor of any
        advice  given  to  it  by  its  counsel   regarding   the  necessity  or
        advisability of amending or supplementing  such Registration  Statement.
        If the Company  shall not propose such  amendment or  amendments  and/or
        supplement  or  supplements  within  fifteen  days after  receipt by the
        Company  of a  written  request  from  the  Distributor  to do  so,  the
        Distributor  may, at its option,  terminate this Agreement.  The Company
        shall not file any amendment to any Registration Statement or supplement
        to any  prospectus  without  giving the  Distributor  reasonable  notice
        thereof in advance;  provided,  however,  that nothing contained in this
        Agreement shall in any way limit the Company's right to file at any time
        such amendments to any Registration Statements and/or supplements to any
        prospectus,  of whatever  character,  as the Company may deem advisable,
        such right being in all respects absolute and unconditional.


1.13.   The  Company  authorizes  the  Distributor  to  use  any  prospectus  or
        statement of additional  information  in the form furnished from time to
        time in connection  with the sale of the Shares.  The Company  agrees to
        indemnify and hold harmless the  Distributor,  its officers,  directors,
        and employees,  and any person who controls the  Distributor  within the
        meaning of Section 15 of the 1933 Act,  free and  harmless  (a) from and
        against  any and  all  claims,  costs,  expenses  (including  reasonable
        attorneys' fees) losses, damages,  charges,  payments and liabilities of
        any  sort  or kind  which  the  Distributor,  its  officers,  directors,
        employees or any such  controlling  person may incur under the 1933 Act,
        under any other statute,  at common law or otherwise,  arising out of or
        based upon: (i) any untrue statement,  or alleged untrue statement, of a
        material  fact  contained  in  the  Company's  Registration   Statement,
        prospectus,  statement of additional  information,  or sales  literature
        (including amendments and supplements thereto), or (ii) any omission, or
        alleged omission,  to state a material fact required to be stated in the
        Company's Registration  Statement,  prospectus,  statement of additional
        information  or sales  literature  (including  amendments or supplements
        thereto),  necessary  to make the  statements  therein  not  misleading,
        provided, however, that insofar as losses, claims, damages,  liabilities
        or expenses arise out of or are based upon any such untrue  statement or
        omission or alleged untrue statement or omission made in reliance on and
        in  conformity  with  information   furnished  to  the  Company  by  the


                                       4

<PAGE>


        Distributor  or  its  affiliated   persons  for  use  in  the  Company's
        Registration   Statement,   prospectus,   or  statement  of   additional
        information  or sales  literature  (including  amendments or supplements
        thereto),  such  indemnification  is not  applicable;  and (b)  from and
        against  any and all such  claims,  demands,  liabilities  and  expenses
        (including  such costs and counsel  fees) which you,  your  officers and
        directors, or such controlling person, may incur in connection with this
        Agreement or the Distributor's performance hereunder (but excluding such
        claims,  demands,  liabilities  and expenses  (including  such costs and
        counsel  fees)  arising  out of or based upon any untrue  statement,  or
        alleged  untrue   statement,   of  a  material  fact  contained  in  any
        registration statement or any prospectus or arising out of or based upon
        any omission,  or alleged omission, to state a material fact required to
        be stated in either any  registration  statement  or any  prospectus  or
        necessary  to make the  statements  in either  thereof not  misleading),
        unless such claims,  demands,  liabilities and expenses  (including such
        costs and  counsel  fees) arise by reason of the  Distributor's  willful
        misfeasance,   bad  faith  or  negligence  in  the  performance  of  the
        Distributor's duties hereunder. The Company acknowledges and agrees that
        in the event that the  Distributor,  at the request of the Company,  are
        required to give indemnification  comparable to that set forth in clause
        (a) of this Section 1.13 to any entity  selling Shares of the Company or
        providing  shareholder  services to shareholders of the Company and such
        entity shall make a claim for  indemnification  against the Distributor,
        the Distributor shall make a similar claim for  indemnification  against
        the Company.

1.14.   The Distributor  agrees to indemnify and hold harmless the Company,  its
        several  officers and  Trustees and each person,  if any, who controls a
        Fund  within the  meaning of Section 15 of the 1933 Act  against any and
        all claims,  costs,  expenses  (including  reasonable  attorneys' fees),
        losses, damages,  charges,  payments and liabilities of any sort or kind
        which the Company, its officers, Trustees or any such controlling person
        may incur under the 1933 Act, under any other statute,  at common law or
        otherwise,  but  only to the  extent  that  such  liability  or  expense
        incurred by the Company,  its officers or Trustees,  or any  controlling
        person   resulting  from  such  claims  or  demands  arose  out  of  the
        acquisition  of any  Shares by any  person  which may be based  upon any
        untrue  statement,  or alleged  untrue  statement,  of a  material  fact
        contained  in  the  Company's  Registration  Statement,   prospectus  or
        statement  of   additional   information   (including   amendments   and
        supplements  thereto),  or any omission, or alleged omission, to state a
        material  fact  required to be stated  therein or  necessary to make the
        statements  therein not  misleading,  if such  statement or omission was
        made in reliance upon  information  furnished or confirmed in writing to
        the Company by the Distributor or its affiliated  persons (as defined in
        the 1940 Act).

1.15.   In any case in which one party hereto (the "Indemnifying  Party") may be
        asked to  indemnify  or hold the other party  hereto  (the  "Indemnified
        Party")  harmless,  the Indemnified  Party will notify the  Indemnifying
        Party  promptly  after  identifying  any  situation  which  it  believes
        presents or appears  likely to present a claim for  indemnification  (an
        "Indemnification  Claim") against the Indemnifying  Party,  although the
        failure to do so shall not prevent  recovery by the  Indemnified  Party,
        and shall  keep the  Indemnifying  Party  advised  with  respect  to all
        developments  concerning such situation.  The  Indemnifying  Party shall
        have  the  option  to  defend  the   Indemnified   Party   against   any
        Indemnification  Claim which may be the subject of this indemnification,
        and, in the event that the  Indemnifying  Party so elects,  such defense
        shall be  conducted  by  counsel  chosen by the  Indemnifying  Party and
        satisfactory to the Indemnified  Party,  and thereupon the  Indemnifying
        Party shall take over complete defense of the Indemnification  Claim and
        the  Indemnified  Party shall sustain no further legal or other expenses
        in respect of such Indemnification Claim. The Indemnified Party will not
        confess any Indemnification  Claim or make any compromise in any case in
        which the Indemnifying  Party will be asked to provide  indemnification,
        except  with  the  Indemnifying   Party's  prior  written  consent.  The
        obligations  of the parties  hereto  under this Section 1.15 and Section
        3.1 shall survive the termination of this Agreement.

        In the  event  that  the  Company  is the  Indemnifying  Party  and  the
        Indemnifying  Party  does not elect to assume  the  defense  of any such
        suit, or in case the Distributor  reasonably does not approve of counsel
        chosen  by the  Company,  or in case  there is a  conflict  of  interest
        between the Company or the  Distributor,  the Company will reimburse the
        Distributor,  its officers,  directors and employees, or the controlling
        person or persons named as defendant or defendants in such suit, for the
        fees and expenses of any counsel  retained by the  Distributor  or them.
        The Company's  indemnification  agreement contained in this Section 1.15
        and Section 3.1 and the Company's representations and warranties in this
        Agreement shall remain operative and in full force and effect regardless
        of any  investigation  made  by or on  behalf  of the  Distributor,  its
        officers,  directors and employees, or any controlling person, and shall
        survive the delivery of any Shares.  This  agreement  of indemnity  will
        inure  exclusively to the Distributor's  benefit,  to the benefit of its
        several officers,  directors and employees, and their respective estates
        and to the benefit of the controlling persons and their successors.  The
        Company agrees promptly to notify the Distributor of the commencement of
        any litigation or proceedings against the Company or any of its officers
        or directors in connection with the issue and sale of any Shares.

1.16.   No Shares  shall be  offered by either the  Distributor  or the  Company
        under any of the  provisions  of this  Agreement  and no orders  for the
        purchase or sale of Shares hereunder shall be accepted by the Company if
        and so long  as  effectiveness  of the  Registration  Statement  then in
        effect or any necessary  amendments thereto shall be suspended under any
        of the  provisions  of the  1933  Act,  or if and so long  as a  current
        prospectus as required by Section 5(b)(2) of the 1933 Act is not on file
        with the SEC; provided,  however, that nothing contained in this Section
        1.16 shall in any way  restrict  or have any  application  to or bearing
        upon the Company's  obligation to redeem Shares  tendered for redemption
        by any  shareholder  in accordance  with the provisions of the Company's
        Registration Statement, Declaration of Company, or bylaws.

1.17.   The  Company  agrees to advise  the  Distributor  as soon as  reasonably
        practical by a notice in writing delivered to the Distributor:

        (a)  of any  request  by the  SEC  for  amendments  to the  Registration
        Statement,  prospectus  or statement of additional  information  then in
        effect or for additional information;

        (b)  in  the  event  of the  issuance  by the  SEC  of  any  stop  order
        suspending the effectiveness of the Registration  Statement,  prospectus
        or statement of additional  information then in effect or the initiation
        by service of process on the Company of any proceeding for that purpose;

        (c)  of the  happening of any event that makes untrue any statement of a
        material  fact  made  in  the  Registration  Statement,   prospectus  or
        statement of additional  information then in effect or that requires the
        making  of a  change  in  such  Registration  Statement,  prospectus  or
        statement  of  additional  information  in order to make the  statements
        therein not misleading; and

        (d)  of all  actions of the SEC with  respect to any  amendments  to any
        Registration   Statement,   prospectus   or  statement   of   additional
        information which may from time to time be filed with the SEC.

        For purposes of this section,  informal requests by or acts of the Staff
        of the SEC shall not be deemed actions of or requests by the SEC.

2.      TERM
        ----

2.1.    This  Agreement  shall become  effective on the date first written above
        and, unless sooner terminated as provided herein,  shall continue for an
        initial  two-year term and  thereafter  shall be renewed for  successive


                                       7


 
<PAGE>



        one-year terms,  provided such  continuance is specifically  approved at
        least annually by (i) the Company's  Board of Trustees or (ii) by a vote
        of a majority (as defined in the 1940 Act and Rule 18f-2  thereunder) of
        the  outstanding  voting  securities  of the Company,  provided  that in
        either  event the  continuance  is also  approved  by a majority  of the
        Trustees  who  are  not  parties  to  this  Agreement  and  who  are not
        interested  persons  (as  defined  in the 1940 Act) of any party to this
        Agreement, by vote cast in person at a meeting called for the purpose of
        voting on such approval.  This Agreement is terminable  without penalty,
        on at least  sixty  days'  written  notice,  by the  Company's  Board of
        Trustees,  by vote of a  majority  (as  defined in the 1940 Act and Rule
        18f-2  thereunder) of the outstanding  voting securities of the Company,
        or by the Distributor.  This Agreement will also terminate automatically
        in the event of its assignment (as defined in the 1940 Act and the rules
        thereunder).

2.2.    In the event a termination notice is given by the Company,  all expenses
        associated with movement of records and materials and conversion thereof
        will be borne by the Company.

3.    LIMITATION OF LIABILITY
      -----------------------

3.1.    The  Distributor  shall not be liable  to the  Company  for any error of
        judgment  or mistake of law or for any loss  suffered  by the Company in
        connection with the performance of its obligations and duties under this
        Agreement,  except  a loss  resulting  from  the  Distributor's  willful
        misfeasance,  bad  faith  or  negligence  in  the  performance  of  such
        obligations and duties, or by reason of its reckless  disregard thereof.
        The Company will indemnify the Distributor  against and hold it harmless
        from  any  and  all  claims,   costs,   expenses  (including  reasonable
        attorneys' fees), losses, damages,  charges, payments and liabilities of
        any sort or kind which may be asserted against the Distributor for which
        the  Distributor  may be held  to be  liable  in  connection  with  this
        Agreement  or the  Distributor's  performance  hereunder (a "Section 3.1
        Claim"),  unless such Section 3.1 Claim resulted from a negligent act or
        omission to act or bad faith by the  Distributor  in the  performance of
        its duties  hereunder.  The  provisions  of  paragraph 1 of Section 1.12
        shall apply to any  indemnification  provided by the Company pursuant to
        this  Section  3.1.  The  obligations  of the parties  hereto under this
        Section 3.1 shall survive termination of this Agreement.

3.2.    Notwithstanding  any provision in this  Agreement to the  contrary,  the
        Distributor's  cumulative  liability  (to the  Company)  for all losses,
        claims, suits, controversies,  breaches, or damages ("Liability Claims")
        for any cause  whatsoever  and regardless of the form of action or legal
        theory,   shall  not  exceed  $500,000.   The  Company  understands  the
        limitation on the Distributor's damages to be a reasonable allocation of
        risk and the Company expressly  consents with respect to such allocation
        of risk.

                                       8

3.3.    Neither  party may assert any cause of action  against  the other  party
        under this  Agreement  that accrued more than two (2) years prior to the
        filing of the suit (or commencement of arbitration proceedings) alleging
        such cause of action.

3.4.    Each party shall have the duty to  mitigate  damages for which the other
        party may become responsible.

3.5.    NOTWITHSTANDING  ANYTHING IN THIS AGREEMENT TO THE CONTRARY, IN NO EVENT
        SHALL THE DISTRIBUTOR,  ITS AFFILIATES OR ANY OF ITS OR THEIR DIRECTORS,
        OFFICERS, EMPLOYEES, AGENTS OR SUBCONTRACTORS BE LIABLE UNDER ANY THEORY
        OF TORT,  CONTACT,  STRICT  LIABILITY OF OTHER LEGAL OR EQUITABLE THEORY
        FOR LOST PROFITS, EXEMPLARY,  PUNITIVE, SPECIAL INCIDENTAL,  INDIRECT OR
        CONSEQUENTIAL  DAMAGES, EACH OF WHICH IS HEREBY EXCLUDED BY AGREEMENT OF
        THE PARTIES  REGARDLESS  OF WHETHER  SUCH DAMAGES  WERE  FORESEEABLE  OR
        WHETHER  EITHER PARTY OR ANY ENTITY HAS BEEN ADVISED OF THE  POSSIBILITY
        OF SUCH DAMAGES.

4.      EXCLUSION OF WARRANTIES
        -----------------------

        THIS IS A  SERVICE  AGREEMENT.  EXCEPT  AS  EXPRESSLY  PROVIDED  IN THIS
        AGREEMENT,  THE  DISTRIBUTOR  DISCLAIMS  ALL  OTHER  REPRESENTATIONS  OR
        WARRANTIES, EXPRESS OR IMPLIED, MADE TO THE COMPANY, A FUND OR ANY OTHER
        PERSON, INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES REGARDING QUALITY,
        SUITABILITY,  MERCHANTABILITY,  FITNESS  FOR  A  PARTICULAR  PURPOSE  OR
        OTHERWISE  (IRRESPECTIVE  OF ANY COURSE OF  DEALING,  CUSTOM OR USAGE OF
        TRADE) OF ANY  SERVICES  OR ANY GOODS  PROVIDED  INCIDENTAL  TO SERVICES
        PROVIDED UNDER THIS AGREEMENT. THE DISTRIBUTOR DISCLAIMS ANY WARRANTY OF
        TITLE  OR  NON-INFRINGEMENT  EXCEPT  AS  OTHERWISE  SET  FORTH  IN  THIS
        AGREEMENT.

5.      MODIFICATION AND WAIVERS
        ------------------------

        No change, termination, modification, or waiver of any term or condition
        of the Agreement  shall be valid unless in writing signed by each party.
        No such writing  shall be effective  as against the  Distributor  unless
        said  writing is  executed by a Senior Vice  President,  Executive  Vice
        President or President of the Distributor.  A party's waiver of a breach
        of any term or condition in the  Agreement  shall not be deemed a waiver
        of any subsequent breach of the same or another term or condition.

 6.    NO PRESUMPTION AGAINST DRAFTER
       ------------------------------

        The  Distributor  and  the  Company  have  jointly  participated  in the
        negotiation  and  drafting of this  Agreement.  The  Agreement  shall be
        construed as if drafted jointly by the Company and the Distributor,  and
        no presumptions  arise favoring any party by virtue of the authorship of
        any provision of this Agreement.

 7.    PUBLICITY
       ---------

        Neither the  Distributor  nor the Company  shall release or publish news
        releases, public announcements,  advertising or other publicity relating
        to this  Agreement  or to the  transactions  contemplated  by it without
        prior review and written approval of the other party; provided, however,
        that either  party may make such  disclosures  as are required by legal,
        accounting or regulatory requirements after making reasonable efforts in
        the circumstances to consult in advance with the other party.

 8.    SEVERABILITY
       ------------

        The parties intend every provision of this Agreement to be severable. If
        a court of competent jurisdiction  determines that any term or provision
        is illegal or invalid for any reason, the illegality or invalidity shall
        not affect the  validity of the  remainder  of this  Agreement.  In such
        case,  the  parties  shall  in good  faith  modify  or  substitute  such
        provision  consistent with the original  intent of the parties.  Without
        limiting the generality of this  paragraph,  if a court  determines that
        any remedy stated in this Agreement has failed of its essential purpose,
        then all other  provisions of this Agreement,  including the limitations
        on liability and exclusion of damages, shall remain fully effective.

 9.    FORCE MAJEURE
       -------------

        No party shall be liable for any default or delay in the  performance of
        its  obligations  under this Agreement if and to the extent such default
        or delay is caused, directly or indirectly, by (i) fire, flood, elements
        of nature or other  acts of God;  (ii) any  outbreak  or  escalation  of
        hostilities, war, riots or civil disorders in any country; (iii) any act
        or omission of the other party or any governmental  authority;  (iv) any
        labor disputes (whether or not the employees'  demands are reasonable or
        within the party's power to satisfy);  or (v)  nonperformance by a third
        party or any similar cause beyond the reasonable  control of such party,
        including    without    limitation,    failures   or   fluctuations   in
        telecommunications   or  other   equipment.   In  any  such  event,  the
        non-performing  party shall be excused from any further  performance and
        observance  of the  obligations  so  affected  only  for so long as such
        circumstances  prevail  and such  party  continues  to use  commercially
        reasonable  efforts to recommence  performance  or observance as soon as
        practicable.

 10.   MISCELLANEOUS
       -------------

10.1.   Any notice or other instrument  authorized or required by this Agreement
        to be  given in  writing  to the  Company  or the  Distributor  shall be
        sufficiently  given if  addressed to the party and received by it at its
        office  set forth  below or at such  other  place as it may from time to
        time designate in writing.

                            with a copy to the Distributor's Chief Legal Officer

10.2.   The laws of the  Commonwealth  of  Massachusetts,  excluding the laws on
        conflicts of laws, and the  applicable  provisions of the 1940 Act shall
        govern the interpretation,  validity, and enforcement of this Agreement.
        To the extent the  provisions  of  Massachusetts  law or the  provisions
        hereof  conflict  with the 1940  Act,  the 1940 Act shall  control.  All
        actions  arising from or related to this  Agreement  shall be brought in
        the state and  federal  courts  sitting in the City of  Boston,  and the
        Distributor  and the Company  hereby submit  themselves to the exclusive
        jurisdiction of those courts.

10.3.   This  Agreement may be executed in any number of  counterparts,  each of
        which shall be deemed to be an original and which  collectively shall be
        deemed to constitute only one instrument.

10.4.   The captions of this Agreement are included for convenience of reference
        only and in no way define or  delimit  any of the  provisions  hereof or
        otherwise affect their construction or effect.

10.5.   This  Agreement  shall be binding upon and shall inure to the benefit of
        the parties hereto and their  respective  successors and is not intended
        to confer upon any other person any rights or remedies hereunder.

11.   CONFIDENTIALITY
      ---------------

11.1.   The parties agree that the Proprietary  Information  (defined below) and
        the contents of this Agreement (collectively "Confidential Information")
        are  confidential  information  of  the  parties  and  their  respective
        licensers.  The Company and the  Distributor  shall exercise  reasonable
        care to safeguard the confidentiality of the Confidential Information of
        the other. The Company and the Distributor may each use the Confidential


                                     11

<PAGE>



        Information only to exercise its rights or perform its duties under this
        Agreement. The Company and the Distributor shall not duplicate,  sell or
        disclose to others the  Confidential  Information of the other, in whole
        or in part, without the prior written permission of the other party. The
        Company  and  the  Distributor  may,  however,   disclose   Confidential
        Information  to its employees  who have a need to know the  Confidential
        Information to perform work for the other,  provided that each shall use
        reasonable  efforts to ensure that the  Confidential  Information is not
        duplicated  or disclosed by its  employees in breach of this  Agreement.
        The Company  and the  Distributor  may also  disclose  the  Confidential
        Information  to  independent  contractors,   auditors  and  professional
        advisors,  provided  they  first  agree  in  writing  to be bound by the
        confidentiality  obligations  substantially  similar to this Section 11.
        Notwithstanding  the  previous  sentence,  in no event shall  either the
        Company or the Distributor disclose the Confidential  Information to any
        competitor of the other without specific, prior written consent.

11.2.   Proprietary Information means:

        (a)   any data or information that is completely sensitive material, and
        not  generally  known to the  public,  including,  but not  limited  to,
        information  about  product  plans,   marketing   strategies,   finance,
        operations, customer relationships,  customer profiles, sales estimates,
        business plans, and internal  performance  results relating to the past,
        present or future business activities of the Company or the Distributor,
        their  respective   subsidiaries   and  affiliated   companies  and  the
        customers, clients and suppliers of any of them;

        (b)   any  scientific  or  technical   information,   design,   process,
        procedure,  formula,  or improvement  that is commercially  valuable and
        secret in the sense that its confidentiality  affords the Company or the
        Distributor a competitive advantage over its competitors; and

        (c)   all confidential or proprietary concepts, documentation,  reports,
        data, specifications,  computer software, source code, object code, flow
        charts,  databases,  inventions,  know-how,  show-how and trade secrets,
        whether or not patentable or copyrightable.

11.3.   Confidential  Information includes,  without limitation,  all documents,
        inventions,  substances, engineering and laboratory notebooks, drawings,
        diagrams,  specifications,  bills of material, equipment, prototypes and
        models, and any other tangible  manifestation of the foregoing of either
        party  which now exist or come into the  control  or  possession  of the
        other.

  
                                     12

<PAGE>




11.4.   The  Company  acknowledges  that  breach  of the  restrictions  on  use,
        dissemination or disclosure of any Confidential Information would result
        in immediate and irreparable harm, and money damages would be inadequate
        to compensate the Distributor  for that harm. The  Distributor  shall be
        entitled  to  equitable  relief,  in  addition  to all  other  available
        remedies, to redress any such breach.

12.     The  Company  and the  Distributor  agree  that the  obligations  of the
        Company  under  the  Agreement  shall  not be  binding  upon  any of the
        Trustees, shareholders, nominees, officers, employees or agents, whether
        past,  present or future, of the Company  individually,  but are binding
        only upon the assets and  property  of the  Company,  as provided in the
        Declaration of Trust.  The execution and delivery of this Agreement have
        been  authorized  by the  Directors  of the  Company,  and  signed by an
        authorized  officer of the  Company,  acting as such,  and neither  such
        authorization  by such Trustees nor such  execution and delivery by such
        officer  shall  be  deemed  to  have  been  made  by any of  them or any
        shareholder  of the Company  individually  or to impose any liability on
        any of them or any shareholder of the Company personally, but shall bind
        only  the  assets  and  property  of  the  Company  as  provided  in the
        Declaration of Trust.

13.     ENTIRE AGREEMENT
        ----------------

        This Agreement,  including all Schedules hereto,  constitutes the entire
        agreement  between the parties with respect to the subject matter hereof
        and  supersedes  all prior and  contemporaneous  proposals,  agreements,
        contracts, representations, and understandings, whether written or oral,
        between the parties with respect to the subject matter hereof.

        IN WITNESS WHEREOF,  the parties hereto have caused this Agreement to be
duly executed all as of the day and year first above written.

      THIS AGREEMENT made on this ________ day of September,  1997,  between the
Potomac Funds, a Massachusetts  business trust (hereinafter  called the "Fund"),
and Firstar Trust Company,  a corporation  organized under the laws of the State
of Wisconsin (hereinafter called "Custodian").

      WHEREAS,  the Fund desires that its securities and cash shall be hereafter
held and administered by Custodian pursuant to the terms of this Agreement,

      NOW, THEREFORE, in consideration of the mutual agreements herein made, the
Fund and Custodian agree as follows:

1.    DEFINITIONS

      "Securities" as used herein includes stocks,  shares,  bonds,  debentures,
notes, mortgages or other obligations, and any certificates,  receipts, warrants
or other instruments  representing rights to receive,  purchase or subscribe for
the same, or evidencing or representing  any other rights or interests  therein,
or in any property or assets.

      "Officers' certificate" shall mean a request or direction or certification
in writing  signed in the name of the Fund by any two of the  President,  a Vice
President,  the  Secretary  and the  Treasurer of the Fund, or any other persons
duly authorized to sign by the Board of Trustees.

      The word "Board" shall mean Board of Trustees of the Fund.

2.    NAMES, TITLES, AND SIGNATURES OF THE FUND'S OFFICERS

      An officer of the Fund will certify to Custodian the names and  signatures

Agreement.

3.    RECEIPT AND DISBURSEMENT OF MONEY

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


       (a)  for the purchase of securities  for the  portfolios of the Fund upon
            the delivery of such securities to Custodian, registered in the name
            of the Fund or of the nominee of Custodian  referred to in Section 7
            or in proper form for transfer;

       (b)  for the purchase or redemption  of shares of beneficial  interest of
            the  Fund  upon  delivery  thereof  to  Custodian,  or  upon  proper
            instructions from the Fund;

       (c)  for the payment of interest,  dividends, taxes, investment adviser's
            fees or operating expenses  (including,  without limitation thereto,
            fees for legal,  accounting,  auditing  and  custodian  services and
            expenses for printing and postage);

       (d)  for  payments  in  connection  with  the  conversion,   exchange  or
            surrender of  securities  owned or subscribed to by the Fund held by
            or to be delivered to Custodian; or

       (e)  for other proper corporate  purposes  certified by resolution of the
            Board.

      Before  making any such  payment,  Custodian  shall  receive (and may rely
upon) an officers'  certificate  requesting  such payment and stating that it is
for a purpose  permitted  under the terms of items (a), (b), (c), or (d) of this
Subsection  A, and also,  in respect of item (e),  upon  receipt of an officers'
certificate  and a certified  copy of a resolution of the Board  specifying  the
amount of such  payment,  setting forth the purpose for which such payment is to
be made, declaring such purpose to be a proper corporate purpose, and naming the
person or persons to whom such payment is to be made, provided, however, that an
officers' certificate and a certified copy of a resolution of the Board need not
precede the  disbursement  of cash for the purpose of  purchasing a money market
instrument,  or any other  security  with same or  next-day  settlement,  if the
President, a Vice President,  the Secretary or the Treasurer of the Funds issues
appropriate  oral or  facsimile  instructions  to Custodian  and an  appropriate
officers'  certificate  and a  certified  copy of a  resolution  of the Board is
received by Custodian within two business days thereafter.

                                        2

<PAGE>



      B.    Custodian is hereby  authorized to endorse and collect all checks,
drafts or other orders for the payment of money  received by Custodian for the
account of the Fund.

      C.  Custodian  shall,  upon receipt of proper  instructions,  make federal
funds  available to the Fund as of specified times agreed upon from time to time
by the Fund and the  Custodian  in the amount of checks  received in payment for
shares of the Fund which are deposited into the Fund's accounts.

      D.  Custodian  shall  collect on a timely basis all income  dividends  and
other payments with respect to registered securities held hereunder to which the
Fund shall be entitled  either by law or  pursuant  to custom in the  securities
business,  and shall  collect on a timely basis all income  dividends  and other
payments  with  respect to bearer  securities  if, on the date of payment by the
issuer,  such securities are held by Custodian or agent thereof and shall credit
such income dividends and other payments, as collected,  to the Fund's custodian
account.  Without  limiting the  generality of the  foregoing,  Custodian  shall
detach and present for payment  all  coupons and other  income  items  requiring
presentation as and when they become due and shall collect  interest when due on
securities  held  hereunder.  Custodian will have no duty or  responsibility  in
connection  therewith,  other than to provide the Fund with such  information or
data as may be necessary to assist the Fund in arranging for the timely delivery
to Custodian of the income to which the Fund is properly entitled.

4.    SEGREGATED ACCOUNTS

      Custodian shall hold in a separate  account,  and physically  segregate at
all times from those of any other persons,  firms or  corporations,  pursuant to
the provisions  hereof, all securities and other investments other than cash and
cash  equivalents  received by it for, or for the account of, the Fund. All such
securities and other investments are to be held or disposed of by Custodian for,
and subject at all times to the  instructions of, the Fund pursuant to the terms
of this  Agreement.  Custodian  shall  have no power  or  authority  to  assign,
hypothecate,  pledge  or  otherwise  dispose  of any  such  securities  or other
investments,  except  pursuant  to the  directive  of the  Fund and only for the
account of the Fund as set forth in Section 5 of this Agreement.

5.    TRANSFER, EXCHANGE, REDELIVERY, ETC. OF SECURITIES

      Custodian  shall have sole power to release or deliver any  securities  of
the Fund held by it pursuant to this  Agreement.  Custodian  agrees to transfer,
exchange or deliver securities held by it hereunder only:

       (a)  for  sales of such  securities  for the  account  of the  Fund  upon
            receipt by Custodian of payment therefor;

       (b)  when such  securities  are called,  redeemed or retired or otherwise
            become payable;

                                       3

<PAGE>


       (c)  for  examination  by any  broker  selling  any  such  securities  in
            accordance with "street delivery" custom;

       (d)  in exchange for, or upon conversion  into, other securities alone or
            other  securities  and cash whether  pursuant to any plan of merger,
            consolidation, reorganization,  recapitalization or readjustment, or
            otherwise;

       (e)  upon  conversion  of such  securities  pursuant  to their terms into
            other securities;

       (f)  upon  exercise of  subscription,  purchase or other  similar  rights
            represented by such securities;

       (g)  for  the  purpose  of  exchanging   interim  receipts  or  temporary
            securities for definitive securities;

       (h)  for the purpose of redeeming in kind shares of  beneficial  interest
            of the Fund upon delivery thereof to Custodian;

       (i)  upon receipt of payment in connection with any repurchase  agreement
            related to such securities entered into by the Fund;

       (j)  for delivery in connection  with any loans of securities made by the
            Fund, but only against receipt of adequate collateral as agreed upon
            from time to time by Custodian and Fund, which may be in the form of
            cash;

       (k)  for delivery as security in  connection  with any  borrowings by the
            Fund  requiring  a pledge of assets  by the Fund,  but only  against
            receipt of amounts borrowed;

       (l)  for delivery in  accordance  with the  provisions  of any  agreement
            among the Fund,  Custodian and a broker-dealer  registered under the
            Securities  Exchange  Act of  1934  and a  member  of  The  National
            Association of Securities Dealers, Inc., relating to compliance with
            the rules of The Options Clearing  Corporation and of any registered
            national  securities  exchange,  or of any similar  organization  or
            organizations,  regarding escrow or other arrangements in connection
            with transactions by the Fund;

       (m)  for release of securities  to designated  brokers under covered call
            options;  provided,  however, that such securities shall be released
            only upon  payment to  Custodian of monies for the premium due and a
            receipt  for the  securities  which are to be held in  escrow.  Upon
            exercise of the option,  or at  expiration,  Custodian  will receive
            from brokers the securities previously deposited. Custodian will act
            strictly in accordance  with proper  instructions in the delivery of
            securities to be held in escrow and will have no  responsibility  or
            liability for any such  securities  which are not returned  promptly
            when due other than to make proper request for such return; or

                                       4

<PAGE>




       (n)  for other proper corporate purposes.

      As to any  deliveries  made by Custodian  pursuant to items (a), (b), (d),
(e), (f), and (g),  securities or cash receivable in exchange therefore shall be
deliverable to Custodian.

      Before making any such  transfer,  exchange or delivery,  Custodian  shall
receive (and may rely upon) an officers'  certificate  requesting such transfer,
exchange or delivery,  and stating that it is for a purpose  permitted under the
terms of each item of this Section 5 above, except item (n) and also, in respect
of item (n), upon receipt of an officers'  certificate and a certified copy of a
resolution of the Board specifying the securities to be delivered, setting forth
the purpose for which such delivery is to be made,  declaring such purpose to be
a proper corporate purpose, and naming the person or persons to whom delivery of
such securities shall be made, provided,  however, that an officers' certificate
and a  certified  copy of a  resolution  of the Board need not  precede any such
transfer,  exchange  or  delivery  of a money  market  instrument,  or any other
security with same or next-day settlement,  if the President,  a Vice President,
the Secretary or the Treasurer of the Funds issues appropriate oral or facsimile
instructions  to  Custodian  and  an  appropriate  officers'  certificate  and a
certified copy of a resolution of the Board is received by Custodian  within two
business days thereafter.

6.    CUSTODIAN'S ACTS WITHOUT INSTRUCTIONS

      Unless  and until  Custodian  receives  an  officers'  certificate  to the
contrary,  Custodian shall: (a) present for payment all coupons and other income
items  held by it for the  account  of the Fund,  which  call for  payment  upon
presentation  and hold the cash received by it upon such payment for the account
of the Fund; (b) collect  interest and cash dividends  received,  with notice to
the Fund,  for the  account  of the Fund;  (c) hold for the  account of the Fund
hereunder all stock dividends, rights and similar securities issued with respect
to any securities held by it thereunder;  and (d) execute, as agent on behalf of
the Fund, all necessary ownership  certificates required by the Internal Revenue
Code or the Income Tax Regulations of the United States  Treasury  Department or
under the laws of any state now or  hereafter  in effect,  inserting  the Fund's
name on such certificates as the owner of the securities covered thereby, to the
extent it may lawfully do so.

7.    REGISTRATION OF SECURITIES

      Except as otherwise directed by an officers' certificate,  Custodian shall
register all  securities,  except such as are in bearer form, in the name of the
Fund or of a registered  nominee of the Fund  assigned by the Fund as defined in
the Internal Revenue Code and any Regulations of the Treasury  Department issued
hereunder or in any provision of any  subsequent  federal tax law exempting such
transaction  from  liability  for stock  transfer  taxes,  and shall execute and
deliver all such certificates in connection therewith as may be required by such
laws or regulations or under the laws of any state. Custodian shall use its best
efforts to the end that the specific securities held by it hereunder shall be at
all times identifiable in its records.

                                       5

<PAGE>



      The  Fund  shall  from  time  to time  furnish  to  Custodian  appropriate
instruments to enable  Custodian to hold or deliver in proper form for transfer,
or to register in the name of its registered  nominee,  any securities  which it
may  hold  for the  account  of the Fund  and  which  may  from  time to time be
registered in the name of the Fund.

8.    VOTING AND OTHER ACTION

      Neither  Custodian  nor any  nominee  of  Custodian  shall vote any of the
securities  held  hereunder  by or for  the  account  of  the  Fund,  except  in
accordance  with  the  instructions   contained  in  an  officers'  certificate.
Custodian shall promptly deliver, or cause to be executed and delivered,  to the
Fund all notices,  proxies and proxy soliciting  materials with relation to such
securities,  such  proxies  to be  executed  by the  registered  holder  of such
securities (if registered  otherwise than in the name of the Fund),  but without
indicating the manner in which such proxies are to be voted.

      Custodian  shall  transmit  promptly to the Fund all  written  information
(including,  without limitation,  pendency of calls and maturities of securities
and  expirations  of rights in  connection  therewith and notices of exercise of
call and put options  written by the Fund) received by Custodian from issuers of
the  securities  being held for the Fund.  With  respect  to tender or  exchange
offers,  Custodian shall transmit  promptly to the Fund all written  information
received by Custodian from issuers of the securities whose tender or exchange is
sought and from the party (or its agent) making the tender or exchange offer.

9.    TRANSFER TAX AND OTHER DISBURSEMENTS

      The  Fund  shall  pay or  reimburse  Custodian  from  time to time for any
transfer taxes payable upon transfers of securities made hereunder,  and for all
other  necessary  and proper  disbursements  and  expenses  made or  incurred by
Custodian in the performance of this Agreement, provided that all such payments,
disbursements and expenses shall be accounted for to the Fund.

      Custodian  shall execute and deliver such  certificates in connection with
securities  delivered  to it or by it under this  Agreement  as may be  required
under the  provisions of the Internal  Revenue Code and any  Regulations  of the
Treasury Department issued thereunder, or under the laws of any state, to exempt
from taxation any exemptable transfers and/or deliveries of any such securities.

10.   CONCERNING CUSTODIAN

      Custodian shall be paid as compensation for its services  pursuant to this
Agreement such  compensation as set forth in Appendix A, which from time to time
may be modified upon written agreement between the two parties.

      Custodian  shall  not be  liable  for any  action  taken in good  faith in
reliance on any officers'  certificate herein described or certified copy of any
resolution of the Board,  and may rely on the  genuineness  of any such document
which it may in good faith believe to have been properly executed.

      Custodian  shall use  reasonable  care in  providing  services to the Fund
pursuant to this  Agreement.  If the Fund requires the Custodian to advance cash
or securities  for any purpose or in the event that the Custodian or its nominee
shall incur or be assessed any taxes, charges, expenses, assessments, claims and
liabilities  (including counsel fees) in connection with the performance of this
Agreement,  except  such as may arise from its or its  nominee's  own  negligent
action,  negligent failure to act or willful misconduct,  it shall be reimbursed
by the Fund for such advances or other costs within a reasonable  time after the
receipt of written notice requesting reimbursement, and any property at any time
held for the account of the Fund shall be security  therefor and should the Fund
fail to repay  Custodian  within a  reasonable  time  after  receipt  of written
notice,  Custodian shall be entitled to utilize available cash and to dispose of
Fund assets to the extent necessary to obtain reimbursement.

     In any and every case where  payment for  purchase of  securities  for the
account of the Fund is made by Custodian in advance of receipt of the securities
purchased,  in the absence of specific written  instructions from the Fund to so
pay in  advance,  Custodian  shall  be  absolutely  liable  to the Fund for such
securities  to the  same  extent  as if the  securities  had  been  received  by
Custodian,  except that in the case of repurchase agreements entered into by the
Fund with a bank which is a member of the Federal Reserve System,  Custodian may
transfer  funds to the  account  of such bank  prior to the  receipt  of written
evidence that the  securities  subject to such  repurchase  agreement  have been
transferred to book-entry into a segregated non-proprietary account of Custodian
or of the safe-keeping receipt,  provided that such securities have in fact been
so transferred by book-entry.

      Custodian  agrees to indemnify  and hold harmless the Fund or its nominees
from all  charges,  expenses,  assessments,  claims and  liabilities  (including
counsel  fees)  incurred  or  assessed  against  the  Fund  or its  nominees  in
connection with the performance of this Agreement, except such as may arise from
the Fund's or its nominees own negligent  action,  negligent  failure to act, or
willful misconduct.

11.   FOREIGN SUBCUSTODIANS

      Custodian is hereby  authorized to assign as subcustodians  for the Fund's
securities  and other assets  maintained  outside the United  States the foreign
banking institutions and foreign securities  depositories designated on Schedule
B hereto ("Foreign Subcustodians"), provided that, if the Custodian utilizes the


                                       7

<PAGE>



services of a Foreign Subcustodian,  the Custodian shall remain fully liable and
responsible  for any losses  caused to the Fund by the Foreign  Subcustodian  as
fully as if the Custodian was directly responsible for any such losses under the
terms of this  Agreement.  Upon receipt of proper  instructions  from the Funds,
together with a certified  resolution  of the Board,  Custodian and the Fund may
agree to amend  Schedule  B hereto  from  time to time to  designate  additional
foreign  banking  institutions  and foreign  securities  depositories  to act as
Foreign Subcustodians.  Upon receipt of proper instructions from Custodian,  the
Fund may instruct  Custodian to cease the  employment of any one or more Foreign
Subcustodians for maintaining custody of the Fund's assets.

      Custodian  shall limit the securities  and other assets  maintained in the
custody of Foreign Subcustodians to the following:  (a) "foreign securities," as
defined in paragraph  (c)(1) of Rule 17f-5 under the  Investment  Company Act of
1940,  as amended (the "1940 Act");  and (b) cash and cash  equivalents  in such
amounts as Custodian or the Fund may  determine  to be  reasonably  necessary to
effect the Fund's foreign securities  transactions.  Custodian shall identify on
its books and records as belonging to the Fund,  the foreign  securities  of the
Fund held by each Foreign Subcustodian.

12.   REPORTS BY CUSTODIAN

      Custodian  shall furnish the Fund daily with a statement  summarizing  all
transactions and entries for the account of Fund. Custodian shall furnish to the
Fund, at the end of every month, a list of the portfolio  securities showing the
adjusted  average  cost of each  issue and the  market  value at the end of such
month.  Custodian  shall  furnish the Fund,  at the close of each quarter of the
Fund's fiscal year, with a list showing cost and market values of the securities
held by it for the Fund hereunder, adjusted for all commitments confirmed by the
Fund as of such close, certified by a duly authorized officer of Custodian.

13.   TERMINATION

      This Agreement may be terminated by the Fund or by Custodian on sixty (60)
days' notice,  given in writing and sent by registered mail to Custodian at P.O.
Box 2054, Milwaukee,  Wisconsin 53201, or to the Potomac Funds at 550 Mamaroneck
Avenue,  Harrison,  NY  10528,  as the case  may be.  Upon  termination  of this
Agreement,  the Fund  shall pay to  Custodian  such  compensation  as may be due
hereunder as of the date of such termination and also shall reimburse  Custodian
for its costs, expenses and disbursements as contemplated by this Agreement.

      If a successor custodian shall be appointed by the Board, Custodian shall,
upon  termination,  deliver  to  such  successor  custodian  at  the  office  of
Custodian,  all securities  duly endorsed and in the form for transfer,  and all
other property of the Fund then held by it hereunder.


                                       8

<PAGE>



      If this Agreement is terminated and no such successor  custodian  shall be
appointed,  Custodian shall, in like manner,  as directed by vote of the holders
of a  majority  of the  outstanding  shares  of the  Fund or upon  receipt  of a
certified  copy of a vote or resolution  of the Board,  deliver at the office of
Custodian and transfer such  securities,  funds and other properties of the Fund
then held by it  hereunder  as  specified  and in  accordance  with such vote or
resolution.

      In the event that no written order  designating  a successor  custodian or
certified copy of a vote or resolution of the Board shall have been delivered to
Custodian on or before the date when the  termination  of this  Agreement  shall
become  effective,  then Custodian  shall have the right to deliver to a bank or
trust  company,  which is a  "bank"  as  defined  in the  1940  Act,  of its own
selection,  having an aggregate capital surplus, and undivided profits, as shown
by its last published report, of not less than $2,000,000, all securities, funds
and other  properties then held by Custodian  hereunder and all instruments held
by it under this Agreement.  Thereafter, such bank or trust company shall be the
successor of Custodian under this Agreement.

      In the event  that  securities,  funds and  other  properties  of the Fund
remain in the possession of Custodian after the date of termination hereof owing
to failure of the Fund to delivery to Custodian  the written  order or certified
copy  referred  to above,  or of the Board to  appoint  a  successor  custodian,
Custodian  shall be entitled to fair  compensation  for its services during such
period as  Custodian  retains  possession  of such  securities,  funds and other
properties  and the  provisions  of this  Agreement  relating  to the duties and
obligations of Custodian shall remain in full force and effect.

      This Agreement may not be assigned by Custodian without the consent of the
Fund, authorized or approved by a resolution of the Board.

14.   DEPOSITS OF SECURITIES IN SECURITIES DEPOSITORIES

      No  provision  of this  Agreement  shall be deemed to  prevent  the use by
Custodian of a central  securities  clearing  agency or  securities  depository,
provided,  however, that Custodian and the central securities clearing agency or
securities   depository   meet  all  applicable   federal  and  state  laws  and
regulations,  and the  Board  approves  by  resolution  the use of such  central
securities clearing agency or securities depository.

15.   RECORDS

      Custodian shall create and maintain all records relating to its activities
and  obligations  under  this  Agreement  in  such a  manner  as will  meet  the
obligations of the Investment Company Act of 1940, as amended,  or the rules and
regulations  promulgated  thereunder.  All such records shall be the property of
the Fund.  Custodian agrees to make any such records available to the Funds upon
request and to preserve  such records for the periods  prescribed in Rule 3 laA2

                                       9

Custodian  pertaining  to its  actions  under  this  Agreement  shall be open to
inspection  and  audit at  reasonable  times by  officers  of,  and of  auditors
employed by, the Fund.

16.   REPORTS TO FUND BY INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

      Custodian shall provide the Fund, at such times as the Fund may reasonably
require,  with  reports  by  independent  certified  public  accountants  on the
accounting system,  internal  accounting control and procedures for safeguarding
securities,  relating  to  the  securities  provided  by  Custodian  under  this
Agreement;  such reports, shall be of sufficient scope and in sufficient detail,
as may  reasonably  be  required  by the  Fund,  and  shall  provide  reasonable
assurance that any material inadequacies would be disclosed by such examination,
and, if there are no such inadequacies, shall so state.

and all losses, claims,  damages,  liabilities or expenses (including reasonable
counsel fees and expenses) resulting from any claim, demand,  action, or suit as
a result of the  negligence  of the Fund (unless  contributed  to by the Agent's
breach of this Agreement or other agreements  between the Fund and the Agent, or
the Agent's own  negligence  or bad faith);  or as a result of the Agent  acting
upon  telephone  instructions  relating to the exchange or  redemption of shares
received by the Agent and  reasonably  believed by the Agent under a standard of
care customarily used in the investment company industry to have originated from
the record  owner of the  subject  shares;  or as a result of acting in reliance

shall apply, it is understood that in any case in which the Fund may be asked to
indemnify  or hold the Agent  harmless,  the Fund  shall be fully  and  promptly
advised of all pertinent facts  concerning the situation in question,  and it is
further  understood  that the Agent will use all  reasonable  care to notify the
Fund promptly  concerning  any  situation  which  presents or appears  likely to
present the  probability of such a claim for  indemnification  against the Fund.
The Fund shall have the option to defend the Agent  against  any claim which may
be the subject of this indemnification. In the event that the Fund so elect, the
Fund will so notify the Agent and  thereupon  the Fund shall take over  complete
defense of the claim, and the Agent shall in such situation  initiate no further
legal or other  expenses  for which it shall  seek  indemnification  under  this
section.  The Agent shall in no case confess any claim or make any compromise in
any case in which the Fund may be asked to  indemnify  the Agent except with the
Fund prior written consent.

            registration statement.

                  (3) Identify interest and dividend accrual balances as of each

      6.    COMPENSATION.  FTC shall be compensated for providing the services
set forth in this  Agreement  in  accordance  with the Fee  Schedule  attached
hereto as Exhibit A and as mutually agreed upon and amended from time to time.

      7.    PERFORMANCE OF SERVICE.

                  A. FTC shall exercise reasonable care and act in good faith in
            the performance of its duties under this Agreement. FTC shall not be
            liable for any error of  judgment  or mistake of law or for any loss
            suffered  by the Fund in  connection  with  matters  to  which  this
            Agreement  relates,   including  losses  resulting  from  mechanical
            breakdowns or the failure of  communication or power supplies beyond
            FTC's control, except a loss resulting from FTC's refusal or failure
            to  comply  with the  terms  of this  Agreement  or from bad  faith,
            negligence,  or willful misconduct on its part in the performance of
            its duties under this Agreement. Notwithstanding any other provision
            of this  Agreement,  the Fund shall  indemnify and hold harmless FTC
            from and against any and all claims, demands,  losses, expenses, and
            liabilities  (whether  with or without  basis in fact or law) of any
            and every nature  (including  reasonable  attorneys' fees) which FTC
            may  sustain or incur or which may be  asserted  against  FTC by any
            person  arising out of or  attributed to any action taken or omitted
            to be  taken  by it in  performing  the  services  hereunder  (i) in
            accordance  with the foregoing  standards,  or (ii) in reliance upon
            any  written  or oral  instruction  for a proper  corporate  purpose
            provided  to FTC by any duly  authorized  officer of the Fund,  such
            duly  authorized  officer  to be  included  in a list of  authorized
            officers  furnished  to FTC  and as  amended  from  time  to time in
            writing by resolution of the Board.

                  In  the  event  of  a  mechanical   breakdown  or  failure  of
            communication  or power supplies beyond its control,  FTC shall take
            all  reasonable  steps to  minimize  service  interruptions  for any
            period that such  interruption  continues beyond FTC's control.  FTC
            will make every  reasonable  effort to  restore  any lost or damaged
            data and correct any errors  resulting  from such a breakdown at the
            expense  of FTC.  FTC  agrees  that it  shall,  at all  times,  have
            reasonable  contingency  plans  with  appropriate  parties,   making
            reasonable provision for emergency use of electrical data processing
            equipment  to  the  extent   appropriate   equipment  is  available.
            Representatives  of the Fund  shall be  entitled  to  inspect  FTC's
            premises  and  operating  capabilities  at any time  during  regular
            business hours of FTC, upon reasonable notice to FTC.

                  Regardless  of the above,  FTC reserves the right to reprocess
            and correct administrative errors at its own expense.

                  B. In order that the indemnification  provisions  contained in
            this section shall apply, it is understood that in any case in which
            the Fund may be asked to  indemnify or hold FTC  harmless,  the Fund
            shall  be  fully  and  promptly   advised  of  all  pertinent  facts
            concerning the situation in question,  and it is further  understood
            that FTC will use all  reasonable  care to notify the Fund  promptly
            concerning any situation which presents or appears likely to present
            the  probability  of such a claim for  indemnification  against  the
            Fund. The Fund shall have the option to defend FTC against any claim
            which may be the subject of this indemnification.  In the event that
            the Fund so  elects,  it will so notify FTC and  thereupon  the Fund
            shall take over complete defense of the claim, and FTC shall in such
            situation  initiate no further legal or other  expenses for which it
            shall seek indemnification  under this section. FTC shall in no case
            confess  any claim or make any  compromise  in any case in which the
            Fund will be asked to  indemnify  FTC except  with the Fund's  prior
            written consent.

                  C. FTC shall  indemnify  and hold the Fund  harmless  from and
            against  any  and  all  claims,  demands,   losses,   expenses,  and
            liabilities  (whether  with or without  basis in fact or law) of any
            and every nature  (including  reasonable  attorneys' fees) which the
            Fund may sustain or incur or which may be asserted  against the Fund
            by any person  arising out of or  attributed  to any action taken or
            omitted  to be taken by FTC as a result of FTC's  refusal or failure
            to comply with the terms of this  Agreement,  or from its bad faith,
            negligence,  or willful misconduct of FTC or any of its employees or
            agents.

      8.  RECORDS.  FTC  shall  keep  records  relating  to the  services  to be
performed hereunder,  in the form and manner, and for such period as it may deem
advisable and is acceptable to the Fund but not inconsistent  with the rules and
regulations of appropriate government authorities, in particular,  Section 31 of
the 1940 Act and the rules thereunder. FTC agrees that all such records prepared
or  maintained  by FTC relating to the services to be performed by FTC hereunder
are the  property  of the  Fund  and  will be  preserved,  maintained,  and made
available  with  such  section  and  rules of the 1940 Act and will be  promptly
surrendered to the Fund on and in accordance with its request.

      9.  CONFIDENTIALITY.  FTC agrees on behalf of itself and its employees and
agents to treat confidentially all records and other information relative to the
Fund and its  shareholders  and shall not  disclose to any other  party,  except
after prior  notification to and approval in writing by the Fund, which approval
shall not be  unreasonably  withheld  and may not be  withheld  where FTC may be
exposed to civil or criminal  contempt  proceedings  for failure to comply after
being requested to divulge such information by duly constituted authorities.

      10. DATA NECESSARY TO PERFORM SERVICES.  The Fund or its agent,  which may
be FTC,  shall  furnish  to FTC the  data  necessary  to  perform  the  services
described  herein at times and in such form as mutually  agreed upon by the Fund
and FTC.

      11.  NOTIFICATION  OF ERROR.  The Fund will notify FTC of any balancing or
control  error caused by FTC within three (3) business days after receipt of any

discovery  of any error or  omission  not  covered in the  balancing  or control
procedure,  or within  three (3)  business  days of  receiving  notice  from any
shareholder.

      12. ADDITIONAL  SERIES. In the event that the Fund establishes one or more
additional  Portfolios  with  respect  to which it  desires  to have FTC  render
accounting services,  under the terms hereof, it shall so notify FTC in writing,

mutually agreed upon in writing by the parties.  However,  this Agreement may be
replaced or modified by a  subsequent  written  instrument  between the parties.
This  Agreement or any rights or  obligations  hereunder  may not be assigned by
either party without the written consent of the other party.

      14.  DUTIES IN THE EVENT OF  TERMINATION.  In the event that in connection
with  termination  a  successor  to  any of  FTC's  duties  or  responsibilities
hereunder is designated by the Fund by written notice to FTC, FTC will promptly,
upon such termination and at the expense of the Fund, transfer to such successor
all  relevant  books,  records,  correspondence  and other data  established  or
maintained by FTC under this  Agreement in a form  reasonably  acceptable to the
Fund (if such form differs from the form in which FTC has  maintained  the same,
the Fund shall pay any expenses  associated with  transferring  the same to such
form),  and will cooperate in the transfer of such duties and  responsibilities,
including  provision for assistance from FTC's personnel in the establishment of
books, records and other data by such successor.

      15. NOTICES.  Notices of any kind to be given by either party to the other

The Potomac Funds
550 Mamaroneck Avenue
Harrison, NY  10528

Ladies and Gentlemen:

      You have  requested  our  opinion  as to  certain  matters  regarding  the
issuance by the Potomac  Funds (the  "Trust") of shares of  beneficial  interest
(the  "Shares") of the Potomac U.S.  Government  Money Market Fund,  the Potomac
Japan/Long Fund, the Potomac  Japan/Short  Fund, the Potomac U.S. Plus Fund, the
Potomac  U.S./Short  Fund,  the Potomac OTC Plus Fund and the Potomac  OTC/Short
Fund,  each a  series  of the  Trust  ("Series").  The  Trust is about to file a
Registration  Statement  on Form N-1A  (the  "Form  N-1A")  for the  purpose  of
registering the Shares to be issued under the Securities Act of 1933, as amended
("1933 Act").

      We have examined  originals or copies  believed by us to be genuine of the
Trust's  Declaration of Trust and By-Laws and such other  documents  relating to
the authorization  and issuance of the Shares as we have deemed relevant.  Based
upon that examination, we are of the opinion that the Shares being registered by
the Form N-1A may be issued in accordance with the Trust's  Declaration of Trust
and By-Laws, subject to compliance with the 1933 Act, the Investment Company Act
of 1940, as amended,  and applicable  state laws regulating the  distribution of
securities,  and when so issued, those Shares will be legally issued, fully paid
and non-assessable.

      The  Trust is an  entity of the type  commonly  known as a  "Massachusetts
business  trust." Under  Massachusetts  law,  Trust  shareholders  could,  under
certain  circumstances,  be held  personally  liable for the  obligations of the
Trust or a Series.  The  Declaration  of Trust  states  that the  creditors  of,
contractors with, and claimants  against,  the Trust or a Series shall look only
to the assets of the Trust or such Series for  payment.  It also  requires  that
notice  of such  disclaimer  be  given in each  note,  bond,  contract  or other
undertaking  issued by or on behalf of the Trust or the Trustees relating to the
Trust. The Declaration of Trust further provides:  (i) for indemnification  from
the  assets  of the  applicable  Series  for  all  losses  and  expenses  of any
shareholder  held personally  liable for the obligations of the Series solely by
virtue of ownership  of Shares of a Series;  and (ii) for a Series to assume the
defense of any claim  against the  shareholder  for any act or obligation of the
Series.  Thus, the risk of a shareholder  incurring financial loss on account of
shareholder liability is limited to circumstances in which the Trust or a Series
would be unable to meet its obligations.


                                             Sincerely yours,

                                             KIRKPATRICK & LOCKHART LLP

                                 POTOMAC FUNDS
                                DISTRIBUTION PLAN



      WHEREAS,  the  Potomac  Funds (the  "Trust")  is engaged in business as an
open-end  management  investment  company  and is  registered  as such under the
Investment Company Act of 1940, as amended (the "1940 Act"); and

      WHEREAS,  the  Trust,  on  behalf  of its  one or more  designated  series
presently  existing  or  hereafter  established   (hereinafter  referred  to  as
"Portfolios"), desires to adopt a Distribution Plan pursuant to Rule l2b-1 under
the 1940 Act and the Board of Trustees of the Trust has determined that there is
a reasonable likelihood that adoption of this Distribution Plan will benefit the
Trust and the shareholders; and

      WHEREAS,  the Trust  intends  to employ a  registered  broker-dealer  as
Distributor of the securities of which it is the issuer;

      NOW,  THEREFORE,  the Trust  hereby  adopts  this  Distribution  Plan (the
"Plan") in accordance  with Rule l2b-1 under the 1940 Act on the following terms
and conditions:

      1.  PAYMENT  OF FEES.  The  Trust  is  authorized  to pay the  Distributor
distribution  and service fees for each  Portfolio  listed on Schedule A of this
Plan, as such schedule may be amended from time to time, on an annualized basis,
at such rates as shall be determined  from time to time by the Board of Trustees
in the manner  provided  for  approval  of this Plan in  Paragraph  4, up to the
maximum rates set forth in Schedule A, as such schedule may be amended from time
to time.  Such fees shall be calculated and accrued daily and paid monthly or at
such other  intervals as shall be determined by the Board in the manner provided
for  approval of this Plan in  Paragraph  4. The  distribution  and service fees
shall be payable  by the Trust on behalf of a  Portfolio  regardless  of whether
those fees exceed or are less than the actual expenses, described in Paragraph 2
below,  incurred  by  the  Distributor  with  respect  to  such  Portfolio  in a
particular year.

      2. DISTRIBUTION AND SERVICE EXPENSES. The fee authorized by Paragraph 1 of
this Plan shall be paid  pursuant to an  appropriate  Distribution  Agreement in
payment  for any  activities  or  expenses  intended  to  result in the sale and
retention  of  Trust   shares,   including   compensation   paid  to  registered
representatives  of the  Distributor  and to  participating  dealers  that  have
entered into sales  agreements with the Distributor,  advertising,  salaries and
other  expenses of the  Distributor  relating to selling or  servicing  efforts,
expenses of organizing and conducting sales seminars,  printing of prospectuses,
statements  of  additional  information  and  reports  for other  than  existing
shareholders,  preparation and  distribution  of advertising  material and sales
literature and other sales promotion expenses, or for providing ongoing services
to shareholders.

<PAGE>



      3.    ADDITIONAL  COMPENSATION.  This  Plan  shall not be  construed  to
prohibit or limit additional  compensation derived from sales charges or other
sources  that may be paid to the  Distributor  pursuant to the  aforementioned
Distribution Agreement.

      4.  THIRD  PARTY  EXPENSES.  Nothing  in this  Plan  shall  operate  or be
construed  to limit the extent to which the  Trust's  investment  adviser or any
other person, other than the Trust, may incur costs and bear expenses associated
with the  distribution  of Shares of  beneficial  interest in a  Portfolio.  The
Trust's  investment adviser may from time to time make payments to third parties
out of its  advisory  fee,  not to exceed  the  amount  of that  fee,  including
payments for fees for shareholder  servicing and transfer agency  functions.  If
such  payments  are deemed to be indirect  financing  of an  activity  primarily
intended  to result  in the sale of shares  issued  by a  Portfolio  within  the
context of Rule 12b-1 under the 1940 Act, such  payments  shall be authorized by
this Plan.

      5. BOARD  APPROVAL.  This Plan shall not take effect  with  respect to any
Portfolio until it has been approved,  together with any related agreements,  by
vote of a majority  of both (a) the Board of Trustees  and (b) those  members of
the Board who are not "interested  persons" of the Trust, as defined in the 1940
Act, and have no direct or indirect  financial interest in the operation of this
Plan or any  agreements  related  to it (the  "Independent  Trustees"),  cast in
person at a meeting or  meetings  called for the  purpose of voting on this Plan
and such related agreements.

      6. RENEWAL OF PLAN. This Plan shall continue in full force and effect with
respect to a Portfolio for  successive  periods of one year from its approval as
set  forth  in  Paragraphs  4 for so long as such  continuance  is  specifically
approved at least  annually in the manner  provided for approval of this Plan in
Paragraph 4.

      7. REPORTS. Any Distribution  Agreement entered into pursuant to this Plan
shall  provide that the  Distributor  shall provide to the Board of Trustees and
the Board  shall  review,  at least  quarterly,  or at such other  intervals  as
reasonably  requested by the Board,  a written report of the amounts so expended
and the purposes for which such expenditures were made.

      8.    TERMINATION.  This  Plan  may  be  terminated  with  respect  to a
Portfolio at any time by vote of a majority of the Independent  Trustees or by
a vote of a majority of the outstanding  voting  securities of such Portfolio,
voting separately from any other Portfolio of the Trust.

                                       2

      9. AMENDMENTS.  Any change to the Plan that would materially  increase the
distribution costs to a Portfolio may not be instituted unless such amendment is
approved in the manner  provided  for board  approval in  Paragraph 4 hereof and
approved by a vote of at least a majority of such Portfolio's outstanding voting
securities,  as  defined  in the 1940  Act,  voting  separately  from any  other
Portfolio  of the  Trust.  Any  other  material  change  to the  Plan may not be
instituted  unless such change is  approved in the manner  provided  for initial
approval in Paragraph 4 hereof.

      10.   NOMINATION  OF  TRUSTEES.  While  this  Plan  is  in  effect,  the
selection  and  nomination  of  Independent  Trustees  of the  Trust  shall be
committed to the discretion of the Independent Trustees then in office.

      11. RECORDS.  The Trust shall preserve copies of this Plan and any related
agreements  and all reports made  pursuant to Paragraph 6 hereof for a period of
not less than six  years  from the date of  execution  of this  Plan,  or of the
agreements  or of such  reports,  as the case may be,  the first two years in an
easily accessible place.
