                          OVERVIEW OF THE POTOMAC FUNDS

The Potomac Funds consist primarily of pairs of funds. Each pair consists of one
"plus"  fund and one  "short"  fund.  Each  "plus" fund is designed to provide a
return that is greater  than the return  provided  by its target  index when the
value of the target index rises.  Unlike  traditional  index funds,  each "plus"
fund (except for the Potomac  U.S.  Plus Fund) seeks to provide a return that is
equal to 125% of the return of a specific  stock market index.  The Potomac U.S.
Plus Fund  seeks to  provide a return  that is equal to 150% of the  return of a
specific stock market index. Each "short" fund is designed to provide investment
results that are opposite of the return of its target index.

As an example,  each of the Potomac OTC Plus Fund and the Potomac OTC/Short Fund
is targeted  to the Nasdaq 100  Index(TRADEMARK)  (Nasdaq 100 Index).  If, for a
given  period of time,  the  Nasdaq 100 Index  gains  20%,  the OTC Plus Fund is
designed to gain  approximately  25% (which is equal to 125% of 20%),  while the
OTC/Short  Fund is  designed  to lose 20%.  Conversely,  if the Nasdaq 100 Index
loses 10%, the OTC/Short  Fund is designed to gain 10%,  while the OTC Plus Fund
is designed to lose 12.5%.

To achieve these results, the Potomac Funds use aggressive investment techniques
such as engaging in futures and options  transactions.  As a result, the Potomac
Funds are designed principally for experienced investors who intend to follow an
asset  allocation  strategy.  There is no assurance  that the Potomac Funds will
achieve their objective.

The  Potomac  Funds also offer a money  market fund which is designed to provide
stability of principal, liquidity and current income.

- --------------------------------------------------------------------------------
POTOMAC OTC FUNDS
- --------------------------------------------------------------------------------


OBJECTIVES:

     The  POTOMAC  OTC  PLUS  FUND  seeks to  provide  investment  returns  that
     correspond to 125% of the  performance of the Nasdaq 100  Index(TRADEMARK).
     If it is  successful in meeting its  objective,  the net asset value of OTC
     Plus Fund shares should increase approximately one and a quarter as much as
     the Nasdaq 100 Index when the  aggregate  prices of the  securities in that
     index rise on a given day. Conversely, the net asset value of shares of the
     OTC Plus Fund should decrease  approximately one and a quarter as much when
     the aggregate prices of the securities in the Nasdaq 100 Index decline on a
     given day.

     The  POTOMAC  OTC/SHORT  FUND  seeks to  provide  investment  returns  that
     inversely correspond (opposite) to the performance of the Nasdaq 100 Index.
     If it is  successful  in  meeting  its  objective,  the net asset  value of
     OTC/Short Fund shares should increase in direct  proportion to any decrease
     in the level of the Nasdaq 100 Index.  Conversely,  the net asset  value of
     shares in the OTC/Short  Fund should  decrease in direct  proportion to any
     increase in the level of the Nasdaq 100 Index.

CORE INVESTMENTS:

     In attempting to achieve their objectives,  the Potomac OTC Funds primarily
     invest directly in the securities of the companies that comprise the Nasdaq
     100  Index.  In  addition,  the  POTOMAC  OTC PLUS  FUND  enters  into long
     positions in stock index futures contracts,  options on stock index futures
     contracts  and  options  on  securities  and on stock  indices  to  produce
     economically  leveraged investment results. The POTOMAC OTC/SHORT FUND also
     enters  into  short  positions  in the  securities  of the  companies  that
     comprise the Nasdaq 100 Index,  stock index futures  contracts,  options on
     stock  index  futures  contracts  and  options on  securities  and on stock
     indices. On a day-to-day basis, the Funds hold U.S.  Government  securities
     and  repurchase  agreements  to  collateralize  these  futures  and options
     contracts.

TARGET INDEX:

     The NASDAQ 100 INDEX(TRADEMARK) is a capitalization-weighted index composed
     of  100 of the  largest  non-financial  domestic  companies  listed  on the
     National  Market tier of The Nasdaq Stock Market.  All companies  listed on
     the index  have a minimum  market  capitalization  of $500  million  and an
     average daily trading  volume of at least  100,000  shares.  The Nasdaq 100
     Index was created in 1985.  The Nasdaq Stock Market is not a sponsor of, or
     in any way affiliated with, the Potomac Funds.


- --------------------------------------------------------------------------------
POTOMAC DOW 30(SERVICEMARK) FUNDS
- --------------------------------------------------------------------------------


OBJECTIVES:

     The POTOMAC DOW  30(SERVICEMARK)  PLUS FUND seeks daily investment  results
     that  correspond  to 125% of the  performance  of the Dow Jones  Industrial
     Average(SERVICEMARK)  (Dow).  If it is successful in meeting its objective,



                                                                               2
<PAGE>

     the  net  asset  value  of  Dow  30  Plus  Fund  shares   should   increase
     approximately  one and a  quarter  as much as the Dow  when  the  aggregate
     prices  of the  securities  that  comprise  the Dow  rise  on a given  day.
     Conversely,  the net asset  value of shares of the Dow 30 Plus Fund  should
     decrease  approximately one and a quarter as much when the aggregate prices
     of the securities comprising the Dow decline on that day.

     The  POTOMAC  DOW  30(SERVICEMARK)/SHORT  FUND seeks to provide  investment
     returns that inversely correspond (opposite) to the performance of the Dow.
     If it is  successful in meeting its  objective,  the net asset value of Dow
     30/Short Fund shares should  increase in direct  proportion to any decrease
     in the level of the Dow.  Conversely,  the net asset value of shares in the
     Dow 30/Short Fund should  decrease in direct  proportion to any increase in
     the level of the Dow.

     The  Potomac  Dow 30  Funds'  investment  objectives  are  not  fundamental
     policies and may be changed by the Potomac Funds' Board of Trustees without
     shareholder approval.

CORE INVESTMENTS:

     In  attempting  to  achieve  their  objectives,  the  Potomac  Dow 30 Funds
     primarily  invest directly in the securities of the companies that comprise
     the Dow. In addition, the POTOMAC DOW 30(SERVICEMARK) PLUS FUND enters into
     long  positions in stock index  futures  contracts,  options on stock index
     futures contracts and options on securities and on stock indices to produce
     economically  leveraged  investment  results.  The Fund also may  invest in
     DIAMONDS, which are publicly-traded index securities.  This allows the Fund
     to invest in a portfolio of  securities  consisting of all of the component
     common stocks of the Dow. The POTOMAC DOW  30(SERVICEMARK)/SHORT  FUND also
     enters  into  short  positions  in the  securities  of the  companies  that
     comprise the DOW,  stock index  futures  contracts,  options on stock index
     futures  contracts and options on  securities  and on stock  indices.  On a
     day-to-day basis, the Funds hold U.S. Government  securities and repurchase
     agreements to collateralize these futures and options contracts.

TARGET INDEX:

     The DOW JONES  INDUSTRIAL  AVERAGE(SERVICEMARK)  consists of 30 of the most
     widely held and actively  traded stocks listed on the U.S.  stock  markets.
     The stocks in the Dow represent companies that typically are dominant firms
     in  their   respective   industries.   Dow  Jones,   Dow  Jones  Industrial
     Average(SERVICEMARK),   DJIA(SERVICEMARK),   and  Dow  30(SERVICEMARK)  are

     correspond to 125% of the performance of the Russell 2000(REGISTERED) Index
     (Russell 2000 Index). If it is successful in meeting its objective, the net
     asset value of Small Cap Plus Fund shares should increase approximately one
     and a quarter as much as the Russell 2000 Index when the  aggregate  prices
     of the  securities in that index rise on a given day.  Conversely,  the net
     asset  value  of  shares  of  the  Small  Cap  Plus  Fund  should  decrease
     approximately  one and a quarter as much when the  aggregate  prices of the
     securities in the Russell 2000 Index decline on that day.


                                                                              3
<PAGE>

     The POTOMAC SMALL CAP/SHORT FUND seeks to provide  investment  returns that
     inversely  correspond  (opposite)  to the  performance  of the Russell 2000
     Index. If it is successful in meeting its objective, the net asset value of
     Small  Cap/Short  Fund shares should  increase in direct  proportion to any
     decrease in the level of the Russell 2000 Index. Conversely,  the net asset
     value of shares in the  Small  Cap/Short  Fund  should  decrease  in direct
     proportion to any increase in the level of the Russell 2000 Index.

     The Potomac  Small Cap Funds'  investment  objectives  are not  fundamental
     policies and may be changed by the Potomac Funds' Board of Trustees without

     Government  securities and  repurchase  agreements to  collateralize  these
     futures and options contracts.

TARGET INDEX:

     The  RUSSELL  2000(REGISTERED)  INDex is  comprised  of the  smallest  2000

     capitalization   of  the  companies   included  in  the  Russell  2000  was
     approximately $526.4 million. That compares to $4.4 billion for the Russell

     market capitalization of the Russell 3000. The Frank Russell Company is not

     approximately  one and a quarter  as much as the  Internet  Index  when the
     aggregate  prices of the  securities  in that  index  rise on a given  day.

     correspond  to  150%  of the  performance  of the  Standard  &  Poor's  500

     decrease  approximately one and a half as much when the aggregate prices of
     the securities in the S&P 500 Index decline on that day.

     The  POTOMAC  U.S./SHORT  FUND seeks to  provide  investment  returns  that
     inversely correspond (opposite) to the performance of the S&P 500 Index. If
     it is  successful  in  meeting  its  objective,  the  net  asset  value  of


                                                                              5

     U.S./Short Fund shares should increase in direct proportion to any decrease
     in the  level of the S&P 500  Index.  Conversely,  the net  asset  value of
     shares in the U.S./Short Fund should  decrease in direct  proportion to any
     increase in the level of the S&P 500 Index.


CORE INVESTMENTS:

     Unlike  traditional  index  funds,  the  Potomac  U.S.  Funds do not invest
     directly in the  securities  of the  companies  that  comprise  the S&P 500
     Index. Rather, the POTOMAC U.S. PLUS FUND invests significantly in Standard
     & Poor's  Depositary  Receipts  (SPDRs),  which are  publicly-traded  index
     securities based on the S&P 500 Index.  This allows the Fund to invest in a
     portfolio of securities consisting of all of the component common stocks of
     the S&P 500 Index.  The Fund also enters into long positions in stock index
     futures contracts,  options on stock index futures contracts and options on
     securities  and  on  stock  indices  to  produce   economically   leveraged
     investment results. The POTOMAC U.S./SHORT FUND enters into short positions
     in  SPDRs,  options  on  stock  index  futures  contracts  and  options  on
     securities and on stock indices. On a day-to-day basis, the Funds hold U.S.
     Government  securities and  repurchase  agreements to  collateralize  these
     futures and options contracts.

TARGET INDEX:

     The  STANDARD & POOR'S 500  COMPOSITE  STOCK  PRICE  INDEX(TRADEMARK)  is a
     capitalization-weighted  index  composed of 500 common  stocks.  Standard &
     Poor's selects the 500 stocks  comprising the S&P 500 Index on the basis of
     market values and industry  diversification.  Most of the stocks in the S&P
     500  Index  are  issued  by the 500  largest  companies,  in  terms  of the
     aggregate market value of their outstanding stock, and generally are listed
     on the New York Stock  Exchange.  Standard & Poor's is not a sponsor of, or
     in any way affiliated with, the Potomac Funds.

POTOMAC JAPAN FUNDS
- --------------------------------------------------------------------------------


OBJECTIVES:

     The  POTOMAC  JAPAN  PLUS FUND  seeks to provide  investment  returns  that
     correspond  to 125% of the  performance  of the  Nikkei  225 Stock  Average
     (Nikkei Index). If it is successful in meeting its objective, the net asset
     value of Japan Plus Fund shares  should  increase  approximately  one and a
     quarter  as much as the  Nikkei  Index  when the  aggregate  prices  of the
     securities  in that index rise on a given  day.  Conversely,  the net asset
     value of shares of the Japan Plus Fund should  decrease  approximately  one
     and a quarter as much when the  aggregate  prices of the  securities in the
     Nikkei Index decline on that day.

     The  POTOMAC  JAPAN/SHORT  FUND seeks to provide  investment  returns  that
     inversely correspond  (opposite) to the performance of the Nikkei Index. If
     it is  successful  in  meeting  its  objective,  the  net  asset  value  of
     Japan/Short  Fund  shares  should  increase  in  direct  proportion  to any
     decrease in the level of the Nikkei Index. Conversely,  the net asset value
     of shares in the Japan/Short  Fund should decrease in direct  proportion to
     any increase in the level of the Nikkei Index.



                                                                              6
<PAGE>

     The Potomac Japan Funds' investment objectives are not fundamental policies
     and  may be  changed  by the  Potomac  Funds'  Board  of  Trustees  without
     shareholder approval.

CORE INVESTMENTS:

     In attempting to achieve their objectives, the Potomac Japan Funds will not
     invest directly in the securities of the companies that comprise the Nikkei
     Index.  Rather,  the  Potomac  Japan  Funds  intend to  invest in  American
     Depositary  Receipts  of such  companies  and  other  securities  that  the
     investment  advisor  believes would provide a return that  approximates the
     Nikkei  Index.  The Potomac Japan Funds also will enter into long and short
     positions, respectively, in stock index futures contracts, options on stock
     index futures contracts and options on securities and on stock indices.  On
     a day-to-day basis, the Funds intend to hold U.S. Government  securities to
     collateralize these futures and options contracts.  In addition,  the Funds
     will enter into repurchase agreements.

TARGET INDEX:

     The NIKKEI  Stock  Average  is a  price-weighted  index of the 225  largest
     Japanese companies listed on the Tokyo Stock Exchange. The Nikkei Index was
     first  published  in 1949 and is  generally  considered  as a proxy for the
     Japanese large-capitalization equity market.


- --------------------------------------------------------------------------------
INVESTMENT TECHNIQUES AND POLICIES
- --------------------------------------------------------------------------------

Rafferty  Asset  Management,  LLC  (Rafferty),  the  investment  advisor to each
Potomac Fund, uses a number of investment techniques in an effort to achieve the
stated goal for each Potomac Fund. For the Potomac Plus Funds, Rafferty attempts
to magnify  the returns of each  Fund's  target  index while the Short Funds are
managed to provide returns inverse (opposite) of each Short Fund's target index.
Rafferty  generally does not use fundamental  securities  analysis to accomplish
such correlation.  Rather,  Rafferty primarily uses statistical and quantitative
analysis to determine the investments  each Potomac Fund makes and techniques it
employs.  As a consequence,  if a Fund is performing as designed,  the return of
the target index will dictate the return for that Fund.

Each  Potomac  Plus Fund  invests  significantly  in futures  contracts on stock
indexes,  options on futures contracts and financial instruments such as options
on  securities  and  stock  indexes  options.   Rafferty  uses  these  types  of
investments to produce economically  "leveraged" investment results.  Leveraging
allows Rafferty to generate a return that is larger than what would be generated
on the invested capital without  leverage,  thus changing small market movements
into larger changes in the value of the investments of a Plus Fund.

While  Rafferty  attempts  to minimize  any  "tracking  error" (the  statistical
measure of the  difference  between the  investment  results of the Fund and the
performance  of its  benchmark),  certain  factors  will  tend to cause a Fund's
investment results to vary from the stated objective.  Rafferty,  however,  does
not expect that a Fund's total returns will vary from its objective by more than
10% over a twelve-month period.


                                                                              7
<PAGE>

It is the  policy  of each  Potomac  Fund to  pursue  its  investment  objective
regardless of market conditions,  to remain substantially fully invested and not
to take  defensive  positions.  A Fund will not  adopt  defensive  positions  by
investing in cash or other instruments in anticipation of an adverse climate for
its target  index.  However,  because it may be difficult  for a Fund to achieve
its  stated investment objective with a low level of assets, Rafferty may invest
the assets of the Potomac Dow 30 Funds,  the Potomac Small  Cap/Short  Fund, the
Potomac Internet Funds and the Potomac Japan Funds in short-term U.S. Government
securities  until the level of net assets is sufficient to permit  investment in
the  appropriate  investments.  As a result,  those Funds may not achieve  their
investment  objectives  during this period. To find out if a Fund has sufficient
assets to invest to attempt to meet its objective, you may call (888) 976-8662.


- --------------------------------------------------------------------------------
RISK FACTORS
- --------------------------------------------------------------------------------

An investment in the Funds entails risks.  The Funds could lose money,  or their
performance could trail that of other investment  alternatives.  Rafferty cannot
guarantee  that any of the Funds will achieve its  objective.  In addition,  the
Funds present some risks not traditionally associated with most mutual funds. It
is important  that investors  closely  review and understand  these risks before
making an investment in the Funds. These and other risks are described below.

RISKS OF INVESTING IN EQUITY SECURITIES AND DERIVATIVES:

     The Funds may invest in publicly issued equity securities, including common
     stocks,  as well as instruments that attempt to track the price movement of
     stock indices.  Investments in common stocks and derivatives in general are
     subject to market risks that may cause their prices to fluctuate over time.
     Fluctuations  in the value of common  stocks in which the Funds invest will
     cause the net asset value of the Funds to fluctuate.

RISKS OF AGGRESSIVE INVESTMENT TECHNIQUES:

     The Funds use  investment  techniques  that may be  considered  aggressive.
     Risks  associated  with  the  use of  futures  contracts,  and  options  on
     securities,   securities   indices,   and  on  futures   contracts  include
     potentially dramatic price changes (losses) in the value of the instruments
     and  imperfect  correlations  between  the  price of the  contract  and the
     underlying security or index. These instruments may increase the volatility
     of the Funds and may  involve a small  investment  of cash  relative to the
     magnitude of the risk assumed.  Investors  should be aware that while index
     futures and options contracts closely correlate with the applicable indices
     over long periods,  shorter-term  deviations  occur. As a result,  a Fund's
     short-term performance will reflect such deviation from its benchmark.

LEVERAGE RISK:

     Each Potomac  Plus Fund employs  leveraged  investment  techniques.  Use of
     leverage  can  magnify  the  effects  of changes in the value of these Plus
     Funds and makes them more  volatile.  The leveraged  investment  techniques
     that these Funds employ should cause  investors in these Funds to lose more
     money in adverse environments.

                                                                              8
<PAGE>

INVERSE CORRELATION RISK:

     Each Potomac  Short Fund is  negatively  correlated to its target index and
     should  lose  money  when its  target  index  rises - a result  that is the
     opposite from traditional equity mutual funds.

RISK OF POOR TRACKING:

     While  Rafferty  does not  expect  that the return of any of the Funds will
     deviate adversely from their respective  investment objectives by more than
     10%, several factors may affect a Fund's ability to achieve its target.  As
     a  consequence,  there can be no  guarantee  that the Funds will be able to
     achieve  this level of  correlation.  A failure to achieve a high degree of
     correlation may prevent a Fund from achieving its investment goal.

RISK OF TRADING HALTS:

     In certain  circumstances,  an exchange may halt trading in securities held
     by a Fund. If such trading  halts are  instituted 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 may be unable to accurately price its outstanding contracts. If a Fund
     is affected by such a halt, it may reject  investors' orders for purchases,
     redemptions, or exchanges received earlier during the business day.

RISK OF EARLY CLOSING:

     The normal close of trading of securities  listed on the Nasdaq and NYSE is
     4:00 p.m. Eastern time.  Unanticipated  early closings may result in a Fund
     being unable to sell or buy  securities on that day. If an exchange  closes
     early on a day when one or more of the Funds needs to execute a high volume
     of securities trades late in the trading day a Fund might incur substantial
     trading losses.

HIGH PORTFOLIO TURNOVER:

     Rafferty expects a significant portion of the Potomac Funds' assets to come
     from professional money managers and investors who use the Funds as part of
     "asset  allocation"  and  "market  timing"  investment  strategies.   These
     strategies often call for frequent trading to take advantage of anticipated
     changes in market  conditions.  Frequent trading could increase the rate of
     the Funds' portfolio  turnover,  forcing realization of substantial capital
     gains and losses and increasing  transaction expenses.  In addition,  while
     Rafferty does not expect it, large  movements of assets into and out of the
     Funds may  negatively  impact their  abilities to achieve their  investment
     objectives or their level of operating expenses.

RISK OF NON-DIVERSIFICATION:

     The Funds (except the Money Market Fund) are  non-diversified,  which means
     that they may invest a high  percentage of their assets in a limited number
     of securities. Since the Funds' are non-diversified, their net asset values
     and total  returns may  fluctuate  more or fall  greater in times of weaker
     markets than a diversified mutual fund.


                                                                              9
<PAGE>

RISKS OF INVESTING IN INTERNET COMPANIES:

     The  Potomac  Internet  Funds  concentrate  their  investments  in Internet
     companies.  In addition,  the OTC Funds may invest a substantial portion of
     their  assets in  Internet  companies  listed on the Nasdaq 100 Index.  The
     market prices of  Internet-related  stocks tend to exhibit a greater degree
     of  market  risk  and  sharp  price   fluctuations   than  other  types  of
     investments.  These  stocks may fall in- and  out-of-favor  with  investors
     rapidly,  which may cause  sudden  selling and  dramatically  lower  market
     prices.  Internet  stocks  also may be  affected  adversely  by  changes in
     technology,   consumer  and  business   purchasing   patterns,   government
     regulation  and/or  obsolete  products or services.  In addition,  a rising
     interest rate environment  tends to negatively  affect Internet  companies.
     Those  Internet  companies  having high market  valuations  may appear less
     attractive to investors,  which may cause sharp decreases in the companies'
     market prices.  Further,  those Internet companies seeking to finance their
     expansion would have increased borrowing costs, which may negatively impact
     their  earnings.  As a result,  these  factors  may  negatively  affect the
     performance of the Internet Index and the Nasdaq 100 Index.

RISKS OF INVESTING IN SMALL CAPITALIZATION COMPANIES:

     Investing in the  securities  of small  capitalization  companies  involves
     greater  risks  and  the  possibility  of  greater  price  volatility  than
     investing in larger capitalization and more established companies.  Smaller
     companies may have limited operating history,  product lines, and financial
     resources, and the securities of these companies may lack sufficient market
     liquidity.  Any of these factors may negatively  impact the  performance of
     the Russell 2000 Index.

RISKS OF INVESTING IN JAPANESE COMPANIES:

     The Potomac  Japan Funds may invest  without  limit  indirectly in Japanese
     securities through ADRs. Investments in Japanese securities involve greater
     risks than investing in domestic securities.  As result, the Funds' returns
     and net asset values may be affected to a large degree by  fluctuations  in
     currency exchange rates,  political,  diplomatic or economic conditions and
     regulatory  requirements in Japan. Japanese laws and accounting,  auditing,
     and financial  reporting  standards typically are not as strict as they are
     in the U.S.,  and  there may be less  public  information  available  about
     foreign companies.

POTOMAC U.S. GOVERNMENT MONEY MARKET FUND
- --------------------------------------------------------------------------------

OBJECTIVES:

     The POTOMAC U.S.  GOVERNMENT MONEY MARKET FUND seeks to provide security of
     principal, current income and liquidity.

CORE INVESTMENTS:

     The  POTOMAC  U.S.  GOVERNMENT  MONEY  MARKET  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 Rafferty to
     present minimal credit risk. The Fund invests exclusively in obligations

                                                                             10
<PAGE>

     issued  or   guaranteed   by  the  U.S.   Government,   its   agencies   or
     instrumentalities  and repurchase  agreements that are fully collateralized
     by such obligations.

INVESTMENT TECHNIQUES AND POLICIES:

     In order to maintain a stable  share price,  the Fund  maintains an average
     dollar-weighted  maturity of 90 days or less.  Securities  purchased by the
     Fund  generally  have  remaining  maturities of 397 days or less,  although
     instruments  subject  to  repurchase   agreements  may  bear  longer  final
     maturities.  The  average  dollar-weighted  maturity  of the Fund  will not
     exceed 90 days.

RISK FACTORS:

     o  The yield paid by the Fund is subject to changes in interest rates. As a
        result,  there is risk that a decline in short-term interest rates would
        lower its yield and the overall return on your investment.

     o  Although  the Fund seeks to  preserve  the value of your  investment  at
        $1.00 per share, it is possible to lose money by investing in the Fund.

     o  Your  investment in the Fund is not insured or guaranteed by the Federal
        Deposit Insurance Corporation or any other government institution.

*    Rafferty Asset Management,  Inc. has contractually  agreed to reimburse the
     Funds for Other  Expenses  through August 31, 2002 to the extent that Total
     Annual Fund Operating  Expenses exceed 2.50% for the Plus Funds,  2.65% for
     the Short Funds and 2.00% for the Money  Market Fund.  If overall  expenses
     fall  below  these  percentage  limitations,  then the Funds may  reimburse
     Rafferty within the following three years.

     of operations.


EXPENSE EXAMPLE:

The tables  below are  intended to help you compare the cost of investing in the
different Classes of the Funds with the cost of investing in other mutual funds.
The tables show what you would have paid if you  invested  $10,000 in each Class
of each Fund over the periods shown and then redeemed all your shares at the end
of those periods. It also assumes that your investment has a 5% return each year
and the Classes'  operating expenses remain the same through the first year. The
expenses shown for the first year are calculated based on the Net Expenses shown
above, taking into account any fee waivers and expense  reimbursements.  For the
other years, the expenses are based on Total Annual Operating Expenses.  Because
the Potomac  Dow Funds,  Potomac  Internet  Funds,  Potomac  Japan Funds and the
Potomac Small Cap/Short Fund were not operational  during the prior fiscal year,
expenses  for 5 Years and 10 Years are not required to be shown.  Although  your
actual costs may be higher or lower, based on these assumptions your costs would
be:

- --------------------------------------------------------------------------------
SHARE PRICES OF THE POTOMAC FUNDS
- --------------------------------------------------------------------------------

A Fund's share price is known as its net asset value (NAV). For all of the Funds
except the U.S. Government Money Market Fund, the share prices are calculated at
4:15 pm  Eastern  time each day the New York Stock  Exchange  (NYSE) is open for
business.  The U.S.  Government Money Market Fund's share price is calculated at
1:00 pm Eastern  time each day the NYSE and  Federal  Bank of New York are open.
Share  price is  calculated  by  dividing  a Fund's  net  assets  by its  shares
outstanding.  The Funds use the following  methods to price  securities  held in
their portfolios:

      o equity  securities,  OTC  securities,  options and futures are valued at
        their last sales price, or if not available, the average of the last bid
        and ask

      o options on futures are valued at their closing  price


                                                                             18
<PAGE>

      o short-term debt securities and money market  securities are valued using
        the "amortized" cost method

      o securities for which a price is unavailable will be valued at fair value
        estimates by the investment  advisor under the  supervision of the Board
        of Trustees


- --------------------------------------------------------------------------------
CLASSES OF SHARES
- --------------------------------------------------------------------------------

The Potomac  Funds  offers three  classes of shares for  investors to purchase -
Investor  Class,  Advisor Class and Broker Class.  Each class charges  different
fees and expenses.

INVESTOR CLASS:

     The Investor  Class is best suited for those  sophisticated  investors  who
     make their own  investment  decisions  without the advice of an  investment
     professional. Investor Class shares are subject to ongoing distribution and
     service (Rule 12b-1) fees of up to 1.00% of their average daily net assets.
     However,  because  Rafferty  has agreed to limit each Fund's  total  annual
     operating expenses,  these fees may be significantly lower than the ongoing
     Rule 12b-1 fees for the Advisor Class and Broker Class shares.

ADVISOR CLASS:

     The Advisor Class is made available through your investment advisor,  bank,
     trust company or other authorized representative (Financial Advisor). As an
     investor in the Advisor Class, you pay no sales charges.  However,  Advisor
     Class shares have  ongoing Rule 12b-1 fees of up to 1.00% of their  average
     daily net assets. Under an agreement with the Funds, your Financial Advisor
     may receive these fees from the Funds. In exchange,  your Financial Advisor
     may provide a number of services, such as:

      o placing your orders and issuing  confirmations,

      o providing  investment advice,  research and other advisory  services,

      o handling  correspondence for individual  accounts,

      o acting as the sole shareholder of record for individual shareholders,

      o issuing  shareholder  statements  and  reports  and

      o executing daily investment "sweep" functions.

     For more specific information on these and other services, you should speak
     to your Financial  Advisor.  Your Financial  Advisor may charge  additional
     account fees for services beyond those specified above.

BROKER CLASS:

     The Broker Class is made available  through your broker or dealer (Broker).
     As an  investor  in the  Broker  Class,  your  investment  is  subject to a
     contingent deferred sales charge (CDSC). This means that if you sell shares
     of a Fund within 6 years of purchase, you may have to pay a sales charge of
     up to 5% on the value of the  shares to be sold.  However,  you will not be



                                                                             19
<PAGE>

     charged a CDSC when you  exchange  Broker  Class shares of one Potomac Fund
     for another.  In addition,  the Broker Class shares have ongoing Rule 12b-1
     fees of up to 1.00% of their average daily net assets.

     The table  below  lists the  different  CDSCs that apply if you sell Broker
     Class  shares  within  6 years  of  purchase.  The  CDSC is  calculated  by
     multiplying  your  original  purchase  cost or the  current  market  value,
     whichever is less by one of the percentages listed in the table. The longer
     you hold your shares, the less of a CDSC you would pay. You may sell shares
     after 6 years with no CDSC.

                          BROKER CLASS DEFERRED CHARGES

              Redemption During:              CDSC on Shares Being Sold:
              -----------------               -------------------------
                   1st year                               5%
                   2nd year                               4%
                   3rd year                               3%
                   4th year                               3%
                   5th year                               2%
                   6th year                               1%
                   After 6 years                          None

   WAIVER OF CDSC:
   --------------

   The CDSC for Broker Class shares currently is waived if the shares are sold:

      o  to make certain  distributions from retirement plans,

      o  due to shareholder death or disability (including shareholders  who own
         shares in joint tenancy with a spouse) or

      o  to close shareholder accounts that do not comply  with the low  balance
         account requirements.

CONVERSION OF BROKER CLASS SHARES:
- ---------------------------------

     If you hold your Broker Class  shares for 8 years,  we  automatically  will
     convert  them to Investor  Class shares at no cost.  In  addition,  we will
     convert any Broker  Class shares  purchased  with  reinvested  dividends or
     distributions.

     At the time of the conversion, you will receive Investor Class shares in an
     amount equal to the value of your Broker Class shares. Because both classes
     have different  prices,  you may receive more or less Investor Class shares
     after the conversion.  However, the dollar amount converted will not change
     so that you have not lost any money due to the conversion.

- --------------------------------------------------------------------------------
RULE 12B-1 FEES
- --------------------------------------------------------------------------------

The Funds have  adopted a  distribution  plan under Rule 12b-1 for each class of
shares.  The Plans  allow the Funds to pay  distribution  and sales fees for the
sale of the Funds' shares and for other shareholder services. Because these fees
are paid out of the Funds'  assets on an  on-going  basis,  over time these fees
will  increase  the cost of your  investment  and may cost you more than  paying
other types of sales charges.


                                                                             20
<PAGE>

Under each Plan, the fees may amount to up to 1.00% of that class' average daily
net assets. The Potomac Funds' Board of Trustees has authorized each Fund to pay
Rule 12b-1 fees equal to 1.00% of the  average  daily net assets of the  Advisor
Class and the Broker Class.  For the Investor Class,  the Board  authorized each

ACCOUNT AND TRANSACTION POLICIES
- --------------------------------------------------------------------------------

ORDER POLICIES:

     You may buy and sell shares of the Funds at their NAV  computed  after your
     order has been  received  in good order.  Purchase  and sell orders will be
     processed  the same day at that day's NAV if received by 3:40 p.m.  Eastern
     Time (or 4:00 p.m. for the Money Market  Fund).  Any order  received  after
     those times will be processed at the NAV next  determined  on the following
     business day.

     There are certain  times when you may be unable to sell shares of the Funds
     or proceeds  may be delayed.  This may occur  during  emergencies,  unusual
     market  conditions  or when the  Funds  cannot  determine  the value of its
     assets or sell its  holdings.  The Funds  reserve  the right to reject  any
     purchase order or suspend offering of their shares.

TELEPHONE TRANSACTIONS:

     For  your  protection,   the  Funds  may  require  some  form  of  personal
     identification prior to accepting your request such as verification of your
     social security number,  account number or other  information.  We also may
     record the conversation for accuracy. During times of unusually high market
     activity  or  extreme  market  changes,  you should be aware that it may be
     difficult to place your request in a timely manner.

SIGNATURE GUARANTEES:

     In certain  instances when you sell shares of the Funds,  we will need your
     signature guaranteed.  Signatures guarantees may be available at your bank,
     stockbroker or a national securities exchange.
     Your signature must be guaranteed under the following circumstances:

     o  if your account registration or address has changed in the last 30 days

     o  if the  proceeds of your sale are mailed to an address  other  than  the
        one listed with the Funds

     o  if the proceeds are payable to a third party

     o  if the sale is greater  than  $100,000

     o  if the wire instructions  on the account are being changed

     o  if there are other unusual situations as determined by the Funds'
        Transfer Agent


                                                                            24
<PAGE>

LOW BALANCE ACCOUNTS:

     If your total account  balance falls below  $10,000,  then we may sell your
     shares  of the  Funds.  We will  inform  you in  writing  30 days  prior to
     selliing  shares.  If you do not bring  your  total  account  balance up to
     $10,000  within 30 days, we may sell shares and send you the  proceeds.  We
     will  not  sell  shares  if  your   account   value  falls  due  to  market
     fluctuations.

MONEY MARKET FUND CHECKING POLICIES:

     You may write checks  against your Money Market Fund account if you request
     and complete a signature  card.  With these checks,  you may sell shares of
     the Fund simply by writing a check for at least  $500.  You may not write a
     check to close your account.  If you place a stop payment order on a check,
     we will charge you $25.

MANAGEMENT OF THE FUNDS

INVESTMENT ADVISOR:

     Rafferty Asset Management,  LLC (Rafferty)  provides investment services to
     the Funds. RAM manages the investment of the Funds' assets  consistent with
     their  investment  objectives,  policies  and  limitations.  RAM  has  been
     managing  mutual funds since June 1997 and has  approximately  $300 million
     assets  under  management  as of  October  1999.  RAM is  located  at  1311
     Mamaroneck Avenue, White Plains, New York 10605.

     Under an investment advisory agreement between the Potomac Funds  and  RAM,
     the Funds pay RAM the following  fees  at an  annualized  rate  based  on a
     percentage  of the  Funds'  daily  net  assets.  The fees  charged  and the
     contractual fees are the same.


                                                                              25

PORTFOLIO MANAGEMENT:

     An investment  committee of Rafferty employees headed by James T. Apple has
     the day-to-day  responsibility  for managing the Potomac  Funds.  Mr. Apple
     founded Rafferty in June 1997 and has been the Chief Investment  Officer of
     the Potomac  Funds since the Funds'  inception.  Previously,  Mr. Apple was
     portfolio  manager for the Rydex OTC Fund from  February  1994 to May 1997.
     From December 1992 to December 1993, he was Director of Investments for The
     Rushmore Funds, Inc.


- --------------------------------------------------------------------------------
DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------

DISTRIBUTIONS:

     Each Fund,  except the Money Market Fund,  distributes  dividends  from net
     investment  income  annually.  The Money  Market Fund  usually  distributes
     dividends from its net investment  income  monthly.  Net investment  income
     generally   consists  of  interest   income  and   dividends   received  on
     investments, less expenses.

     Each Fund,  except the Money Market Fund, also distributes any realized net
     capital  gains  annually.  A Fund  has  capital  gains  when it  sells  its
     portfolio assets for a profit.  The tax consequences will vary depending on
     how long a Fund has held the asset.  Distributions of net gains on the sale
     of an asset held for one year or less are taxed as ordinary  income.  Sales
     of assets held longer than one year (long-term  capital gains) are taxed at
     lower capital gains rates.

     Dividends  and net capital gains will be  reinvested  automatically  at NAV
     unless you  request  otherwise  in  writing.  Normally,  distributions  are
     taxable  events  for  shareholders  whether  or not the  distributions  are
     received in cash or reinvested.

TAXES:

     The following  table  illustrates the potential tax liabilities for taxable
accounts:


     ---------------------------------------------------------------------------
     Type of Transaction                           Tax Status*

     ---------------------------------------------------------------------------
     Dividends                                     Ordinary income rate
     Short-term capital gains                      Ordinary income rate



                                                                             26

     Sale or exchange of Fund shares owned         Long-term  capital gains or
     for more than one year                        losses (capital  gains  rate)
     Sale or exchange of Fund shares owned         Gains are taxed at the same
     for less than one year                        rate as ordinary income;
                                                   losses are subject to special
                                                   rules
- --------------------------------------------------------------------------------

     *   Tax consequences for  tax-deferred  retirement  accounts or non-taxable
         shareholders  may be different.  You should consult your tax specialist
         for more information about your personal situation.

     If you are a  non-retirement  account holder,  then each year, we will send
     you a Form  1099  that  tells  you the  amount  of Fund  distributions  you
     received for the prior calendar year, the tax status of these distributions
     and a list of reportable sale  transactions.  Normally,  distributions  are
     taxable in the year you receive them. However,  any distributions  declared
     in the last three months of the year  generally  are taxable as if received
     on  December  31 of the year they are  declared  and paid in January of the
     following year.

     If you are a  non-corporate  shareholder  and do not provide the Funds with
     your correct taxpayer  identification number (normally your social security
     number),  the Funds are  required to withhold 31% of all  dividends,  other
     distributions  and  sale  proceeds  payable  to you.  If you are  otherwise
     subject to backup withholding,  we also are required to withhold and pay to
     the IRS 31% of your distributions.  Any tax withheld may be applied against
     your tax liability  when you file your tax return.  You may be subject to a
     $50 fee for any penalties imposed on the Funds by the IRS.


- --------------------------------------------------------------------------------
YEAR 2000
- --------------------------------------------------------------------------------

The Funds could be affected  adversely if the computer systems used by Rafferty,
the Funds' other  service  providers,  or companies in which the Funds invest do
not properly  process and calculate  information that relates to dates beginning
on January 1, 2000 and  beyond.  The Funds have  received  representations  from
Rafferty  and  its  other  service  providers   regarding  their  readiness  and
initiatives for the Year 2000 issue. However, due to the uncertainty of the Year
2000  issue and the Funds'  reliance  on various  service  providers  to perform
essential  functions,  a Fund could have  difficulty  calculating  its net asset
value,  processing orders for share sales and delivering  account statements and
other  information to  shareholders.  There can be no assurance that these steps
taken by the Funds'  service  providers  will be sufficient to avoid and adverse
impact.

- --------------------------------------------------------------------------------
MASTER/FEEDER STRUCTURE OPTION
- --------------------------------------------------------------------------------

The Funds may in the future operate under a master/feeder structure.  This means
that each Fund would be a "feeder" fund  that attempts to meet its  objective by
investing all its investable  assets in a "master" fund with the same investment
objective.  The "master" fund would purchase  securities for  investment.  It is
expected  that any such  investment  company  would be  managed by  Rafferty  in
substantially  the same manner as the Funds.  If  permitted by law at that time,
the Board of Trustees may approve the implementation of such a structure for the
Funds without seeking shareholder approval. However,  the   Trustee's   decision

                                                                             27
<PAGE>

will  be  made  only if  theinvestments  in the  master  funds  are 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.  You also
will receive 30 days notice  prior to the  implementation  of the  master/feeder
structure.

- --------------------------------------------------------------------------------
FINANCIAL HIGHLIGHTS
- --------------------------------------------------------------------------------

The financial  highlights tables are intended to help you understand each Fund's
financial  performance since the Funds' commenced operation.  The information in
the  tables  has  been  audited  by   PricewaterhouseCoopers   LLP,  the  Funds'
independent  accountants.  Certain information  reflects financial results for a
single Fund share.  The total  returns in the table  represent  the rate that an
investor  would have  earned (or lost) on an  investment  in the Fund  (assuming
reinvestment of all dividends and distributions).  Financial  highlights are not
available for the Potomac Small  Cap/Short  Fund, the Potomac Dow 30 Funds,  the
Potomac  Internet  Funds  and the  Potomac  Japan  Funds  because  they have not
commenced active operations.  More information about the Funds is found in their
Annual and Semi-Annual Reports, which you may obtain upon request.

The Potomac Funds (the "Trust") is a management  investment  company,  or mutual
fund, which offers to the public thirteen  separate  investment  portfolios (the
"Funds").  The Funds are designed  principally  for  experienced  investors  who
intend to follow an 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,  each of which  attempts  to
provide  results  correlating to a specific  index.  The "plus" fund attempts to
provide investment results that correlate to its target index, while the "short"
fund attempts to provide  investment  results that are opposite of the return of
its target index. In particular,  the following  Funds seek  investment  results
that correspond over time to the following target indices:

                                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 thirteen  separate series
to the  public:  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"),  the  Potomac  Dow
30(SERVICEMARK)   Plus   Fund   ("Dow   30  Plus   Fund"),   the   Potomac   Dow
30(SERVICEMARK)/Short Fund ("Dow 30/Short Fund"), the Potomac Internet Plus Fund
("Internet Plus Fund"), the Potomac Internet/Short Fund ("Internet Short Fund"),
the Potomac Japan Plus Fund ("Japan Plus Fund"),  the Potomac  Japan/Short  Fund
("Japan  Short Fund"),  the Potomac Small Cap Plus Fund ("Small Cap Plus"),  the
Potomac Small Cap/Short Fund ("Small Cap Short") and the Potomac U.S. Government
Money Market Fund ("Money Market Fund") (collectively,  the "Funds").  The Trust
may offer additional series in the future.

Each Fund offers three classes of shares:  the Investor Class, the Advisor Class
and the Broker Class.  The Investor  Class shares are designed for sale directly
for  investors  without  a sales  charge.  The  Advisor  Class  shares  are made
available through investment  advisers,  bank, trust company or other authorized
representative  without a sales  charge but are subject to a 1.00%  distribution
and service fee.  The Broker  Class shares are sold through  brokers and dealers
and are  subject to a 5%  maximum  contingent  deferred  sales  charge  ("CDSC")
declining over a six-year period.

The Funds are designed  principally for experienced  investors  seeking an 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 target index.  The terms "plus"
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.

                           CLASSIFICATION OF THE FUNDS

Each Fund (other than the Money  Market Fund) is a  "non-diversified"  series of
the Trust  pursuant  to the 1940  Act.  A Fund is  considered  "non-diversified"
because a  relatively  high  percentage  of its  assets may be  invested  in the
securities  of a limited  number of issuers.  To the extent that a Fund  assumes
large  positions in the securities of a small number of issuers,  the fund's net
asset value may fluctuate to a greater extent than that of a diversified company
as a result of changes in the financial  condition or in the market's assessment
of the issuers,  and the Fund may be more  susceptible  to any single  economic,
political or regulatory occurrence than a diversified 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 meet
certain diversification standards at the end of each quarter of its tax year.

<PAGE>

                       INVESTMENT POLICIES AND TECHNIQUES

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
objective.

AMERICAN DEPOSITORY RECEIPTS ("ADRS")

The OTC Plus Fund,  OTC/Short Fund,  Small Cap Plus Fund,  Small Cap/Short Fund,
Internet Plus Fund,  Internet/Short  Fund,  Japan Plus Fund and Japan/Short Fund
may invest in ADRs. The OTC/Short Fund,  Small  Cap/Short  Fund,  Internet/Short
Fund and Japan/Short Fund may sell ADRs 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.
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.

FOREIGN SECURITIES

The  Japan  Plus  Fund  and the  Japan/Short  Fund  (each,  a "Japan  Fund"  and
collectively,  the "Japan  Funds") may invest in ADRs of companies that comprise
the Nikkei 225 Index. The Japan Funds also may have indirect exposure to foreign
securities  through  investments  in stock index futures  contracts,  options on
stock index futures contracts and options on securities and on stock indices.

Investing in foreign  securities  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.

                                       4

ILLIQUID INVESTMENTS AND RESTRICTED SECURITIES

Each Fund may purchase and hold illiquid  investments,  No Fund will 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 of Trustees
("Board" or "Trustees")  or Rafferty  Asset  Management,  LLC  ("Rafferty")  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)  over-the-counter  ("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 and (5) restricted
securities not determined to be liquid pursuant to guidelines established by the
Board.  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 Rafferty  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 establishes a "safe harbor" from the registration  requirements of the
1933 Act for resales of certain  securities to qualified  institutional  buyers.
Institutional  markets for restricted securities that have developed as a result
of Rule 144A provide both readily  ascertainable  values for certain  restricted
securities  and  the  ability  to  liquidate  an  investment  to  satisfy  share
redemption  orders.  An insufficient  number of qualified  institutional  buyers
interested in purchasing Rule 144A-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.

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 or other financial
indicators, consistent with its investment objective.  Indexed securities may be
debt securities or deposits whose value at maturity or coupon rate is determined

                                       5
<PAGE>

by reference to a specific  instrument or statistic.  Recent  issuers of indexed
securities  have  included  banks,  corporations  and  certain  U.S.  Government
agencies.

The  performance  of  indexed  securities  depends  to a  great  extent  on  the
performance  of the security 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.  Certain indexed  securities that are
not  traded on an  established  market  may be deemed  illiquid.  See  "Illiquid
Investments and Restricted Securities" above.

The  U.S.  Plus  Fund may  invest  in  Standard  &  Poor's  Depositary  Receipts
("SPDRs").  SPDRs represent ownership in the SPDR Trust, a unit investment trust
that holds a portfolio of common stocks designed to track the price  performance
and  dividend  yield of the  Standard & Poor's 500  Composite  Stock Price Index
("S&P 500 Index"),  and whose shares trade on the American Stock  Exchange.  The
value of SPDRs  fluctuates in relation to changes in the value of the underlying
portfolio  of common  stocks.  The market  price of SPDRs,  however,  may not be
equivalent to the pro rata value of the S&P 500 Index.  SPDRs are subject to the
risks of an investment in a broadly based portfolio of common stocks.

The Dow 30 Plus Fund may invest in DIAMONDS(SERVICEMARK).  DIAMONDS represent an
investment in a unit investment trust ("DIAMONDS  Trust"),  which owns shares in
proportion to the weightings of the stocks  comprising the Dow Jones  Industrial
Average  ("DJIA").  The DIAMONDS Trust is structured so that its shares trade at
approximately  1/100 (one  one-hundredth) of the value of the DJIA. The DIAMONDS
Trust's shares trade on the American Stock Exchange  ("AMEX").  An investment in
DIAMONDS  is  subject  to risks  similar  to those  of other  diversified  stock
portfolios,  including  market  volatility  and that the general  level of stock
prices may decline. Although DIAMONDS are designed to provide investment results
that  generally  correspond to the price and yield  performance of the DJIA, the
DIAMONDS Trust may not be able to exactly  replicate the performance of the DJIA
because of trust expenses and other factors.

An  investment  in  SPDRs  and  DIAMONDS  are  considered  investments  in other
investment companies discussed below.

The Japan  Funds may invest in  currency-indexed  securities.  These  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.

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

                                       6
<PAGE>

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
addition to the fees and expenses Fund shareholders  directly bear in connection
with the Fund's own operations.

OPTIONS, FUTURES AND OTHER STRATEGIES

GENERAL.  Each Fund (other than the Money Market  Fund) may use certain  options
(both traded on an exchange and OTC), futures contracts  (sometimes  referred to
as  "futures")  and  options  on  futures  contracts  (collectively,  "Financial
Instruments") as a substitute for a comparable market position in the underlying
security,  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.

The use of Financial  Instruments  is subject to applicable  regulations  of the
SEC, the several  exchanges upon which they are traded and the Commodity Futures
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,  Rafferty may discover  additional  opportunities in connection with
Financial  Instruments  and  other  similar  or  related  techniques.  These new
opportunities  may become  available  as Rafferty  develops new  techniques,  as
regulatory  authorities  broaden the range of permitted  transactions and as new
Financial  Instruments or other  techniques are developed.  Rafferty 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 Rafferty's ability
to predict movements of the overall securities markets, which requires different
skills  than  predicting  changes in the prices of  individual  securities.  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 stock market trends by
Rafferty  may still not  result in a  successful  transaction.  Rafferty  may be
incorrect in its  expectations as to the extent of market  movements or the time
span  within  which the  movements  take place  which,  thus,  may result in the
strategy being unsuccessful.

(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 or no correlation

                                       7

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.

(4) Losses may arise due to  unanticipated  market  price  movements,  lack of a
liquid  secondary  market for any particular  instrument at a particular time or
due to losses from premiums paid by a Fund on options transactions.

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  or other  options  or futures  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 Bank Milwaukee,  N.A.  ("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.  Options  currently  are traded on the Chicago Board
Options  Exchange  ("CBOE"),  the AMEX and other  exchanges,  as well as the OTC
markets.

By buying a call option on a security,  a Fund has the right,  in return for the
premium paid, to buy the security  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  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 underlying

                                       8
<PAGE>

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  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.

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,  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  able  to  close  out an OTC  option
position at a favorable price prior to expiration. In the event of insolvency of
the counterparty,  a Fund might be unable to close out an OTC option position at
any time prior to its expiration.

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

OPTIONS ON INDICES. 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.  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 as the  Philadelphia  Stock
Exchange Over-the-Counter Index.



                                        9

<PAGE>

Each of the exchanges has established  limitations  governing the maximum number
of call or put  options  on the same  index  that may be bought or  written by a
single investor,  whether acting alone or in concert with others  (regardless of
whether such options are written on the same or different  exchanges or are held
or written on one or more accounts or through one or more brokers).  Under these
limitations,  option positions of all investment  companies  advised by Rafferty
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.

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

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

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

OTC Foreign Currency  Options.  OTC foreign currency options that may be used by
the Japan Plus 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. A futures contract obligates
the seller to deliver  (and the  purchaser to take  delivery  of) the  specified
security on the  expiration  date of the  contract.  An index  futures  contract

                                       10
<PAGE>

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 or index. The extent of a 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 only purchase
and sell futures contracts and options on futures contracts that are traded on a
U.S. exchange or board of trade.

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 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.


                                       11
<PAGE>

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.

To the extent that a Fund enters into  futures  contracts  or options on futures
contracts, in each case other than for BONA FIDE hedging purposes (as defined by
the Commodity Futures Trading Commission ("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 and options on futures contracts.

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

FOREIGN CURRENCY STRATEGIES - RISK FACTORS.  Each Japan Fund may use options and
futures  contracts on Japanese Yen, as described above, and forward contracts 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,
each Japan Fund could be  disadvantaged  by having to deal in the odd-lot market

                                       12
<PAGE>

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

The cost to each Japan 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 Japan Fund enters into a forward currency contract,  it relies
on the  counterparty to make or take delivery of the underlying  currency at the
maturity of the contract.  Failure by the  counterparty to do so would result in
the loss of any expected benefit of the transaction.

As is the case  with  futures  contracts,  purchasers  and  sellers  of  forward
currency  contracts can enter into offsetting closing  transactions,  similar to
closing   transactions   on  futures   contracts,   by  selling  or  purchasing,
respectively,  an  instrument  identical  to the  instrument  purchased or sold.
Secondary  markets generally do not exist for forward currency  contracts,  with
the result that closing transactions  generally can be made for forward currency
contracts only by negotiating directly with the counterparty. Thus, there can be
no  assurance  that a Japan  Fund  would 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 Japan Fund may be unable to close out
a forward  currency  contract at any time prior to maturity.  In either event, a
Japan 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.


                                       13
<PAGE>

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 Japan  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.  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.

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. 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. 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" above.

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. 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.  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.

SHORT SALES

The  U.S./Short   Fund,   the  OTC/Short   Fund,  the  Dow  30/Short  Fund,  the
Internet/Short  Fund,  the Small  Cap/Short  Fund and the  Japan/Short  Fund may
engage in short sale 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

                                       14
<PAGE>

borrowed  by  purchasing  the  security  at the  market  price  at the  time  of
replacement.  The price at such time may be more or less than the price at which
the security was sold by the Fund.  Until the security is replaced,  the Fund is
required to pay to the lender  amounts equal to any dividends that accrue during
the period of the loan.  The  proceeds of the short sale will be retained by the
broker, to the extent necessary to meet the margin requirements, until the short
position is closed out.

Until a Fund closes its short position or replaces the borrowed stock,  the Fund
will: (1) maintain an account  containing  cash or liquid assets at such a level
that (a) the amount deposited in the account plus that amount deposited with the
broker as  collateral  will equal the current  value of the stock sold short and
(b) the amount  deposited  in the  account  plus the amount  deposited  with the
broker as collateral  will not be less than the market value of the stock at the
time the stock was sold short; or (2) otherwise cover the Fund's short position.

The U.S. Plus Fund,  the OTC Plus Fund,  the Dow 30 Plus Fund, the Internet Plus
Fund,  the Small Cap Plus Fund and the Japan  Plus Fund each also 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").

U.S. GOVERNMENT SECURITIES

The Money Market Fund invests in  Securities  issued or  guaranteed  by the U.S.
Government or its agencies or instrumentalities  ("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 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.

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,
the Federal  National  Mortgage  Association  ("Fannie  Mae"),  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 Rafferty is satisfied that the credit risk involved is
acceptable.

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.

OTHER INVESTMENT RISKS AND PRACTICES

BORROWING. The U.S. Plus Fund, OTC Plus Fund, the Internet Plus Fund, the Dow 30
Plus Fund,  the Japan Plus Fund and the Small Cap Plus Fund may borrow money for
investment purposes, which is a form of leveraging.  Leveraging investments,  by
purchasing  securities  with borrowed  money,  is a speculative  technique  that
increases investment risk while increasing investment opportunity. Leverage will
magnify  changes  in a Fund's  net  asset  value  and on a  Fund's  investments.
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 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. The use
of derivatives in connection with leverage creates the potential for significant
loss.

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

As  required by the 1940 Act, a Fund must  maintain  continuous  asset  coverage
(total assets,  including assets acquired with borrowed funds,  less liabilities
exclusive of  borrowings)  of 300% of all amounts  borrowed.  If at any time the
value of the required asset coverage declines as a result of market fluctuations

                                       16
<PAGE>

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 Rafferty deems appropriate in connection with any borrowings.

LENDING  PORTFOLIO  SECURITIES.  Each Fund may lend portfolio  securities with a
value not  exceeding  33 1/3% (15% 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.

PORTFOLIO  TURNOVER.  The Trust anticipates that investors in the Funds, as part
of an asset allocation investment strategy,  frequently will redeem Fund shares,
as well as exchange their Fund shares for shares of other Funds. A Fund may have
to dispose of certain portfolio investments to maintain sufficient liquid assets
to meet such redemption and exchange requests,  thereby causing a high portfolio
turnover.  Because each Fund's  portfolio  turnover rate depends  largely on the
purchase,  redemption and exchange activity of its investors, it is difficult to
estimate each Fund's actual turnover rate.

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. If, for
example, options and futures were included in the calculation,  then each Fund's
portfolio   turnover  rate,   except  for  the  Money  Market  Fund,   would  be
approximately 500%.

TRACKING ERROR

While  the Funds do not  expect  their  returns  over a  twelve-month  period to
deviate from their  respective  target  indices by a significant  percentage due
solely to  tracking  error,  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 target index being held by
a Fund and securities not included in the target index 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 target index over time due to the
mathematical effects of leveraging).

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 target index.

In the case of the Funds whose net asset values move inversely from their target
indices (the U.S./Short Fund, OTC/Short Fund, Dow 30/Short Fund,  Internet/Short
Fund, Japan/Short Fund, the Small Cap/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  target index 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 a Fund achieved a perfect inverse  correlation  with its target
index on every  trading day over an extended  period and the level of returns of
that index significantly  decreased during that period, a compounding effect for
that period would result, causing an increase in the Fund's net asset value by a
percentage that is somewhat greater than the percentage that the index's returns
decreased.  Conversely,  if a Fund maintained a perfect inverse correlation with
its  target  index over an  extended  period and if the level of returns of that
index  significantly  increased  over that period,  a  compounding  effect would
result,  causing a decrease of the Fund's net asset value by a  percentage  that
would be somewhat less than the percentage that the index returns increased.


                             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.

                                       18
<PAGE>

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:

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

     (1)  that  the  Fund  may  issue  senior   securities  in  connection  with
     transactions in options, futures, options on futures and forward contracts,

     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,  Rafferty is responsible for
decisions  to  buy  and  sell   securities  for  each  Fund,  the  selection  of
broker-dealers  to effect the  transactions,  and the  negotiation  of brokerage
commissions,  if any.  Rafferty 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.

When selecting a broker or dealer to execute  portfolio  transactions,  Rafferty
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
Rafferty.

In effecting portfolio transactions for the Funds, Rafferty seeks best execution
of trades  either (1) at the most  favorable  price and  efficient  execution of
transactions  or (2) with  respect to agency  transactions,  at a higher rate of
commission if reasonable in relation to brokerage and research services provided
to the Funds or Rafferty.  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 Rafferty from obtaining
a high quality of brokerage and research  services.  In seeking to determine the
reasonableness of brokerage commissions paid in any transaction, Rafferty 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.

Rafferty may use  research  and services  provided to it by brokers in servicing
all the  Funds;  however,  not all  such  services  may be used by  Rafferty  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 Rafferty,  this information and these services
are of indeterminable value and would not reduce Rafferty'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

                                       22
<PAGE>

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.

Aggregate  brokerage  commissions  paid by U.S. Plus Fund for the period October
20,  1997 to August 31,  1998 and the fiscal  year  ended  August 31,  1999 were
$8,938 and  $42,360,  respectively.  Those  commissions  were paid on  brokerage
transactions worth $174,191,426 and $1,099,600,547, respectively.

Aggregate brokerage  commissions paid by U.S./Short Fund for the period November
7, 1997 to August 31, 1998 and the fiscal year ended August 31, 1999 were $3,618
and $13,861, respectively. Those commissions were paid on brokerage transactions
worth $78,849,094 and $459,448,390, respectively.

Aggregate brokerage commissions paid by OTC Plus Fund for the period October 20,
1997 to August 31,  1998 and the fiscal  year ended  August 31, 1999 were $7,628
and $34,558, respectively. Those commissions were paid on brokerage transactions
worth $9,942,393 and $72,067,551, respectively.

Aggregate  brokerage  commissions  paid by OTC/Short Fund for the period October
16, 1997 to August 31, 1998 and for the fiscal  year ended  August 31, 1999 were
$858  and  $1,521,  respectively.  Those  commissions  were  paid  on  brokerage
transactions worth $698,439 and $50,906,648, respectively.

Aggregate  brokerage  commissions paid by Small Cap Plus for the period February
16,  1999 to August  31,  1999 were  $151,137.  Those  commissions  were paid on
brokerage transactions worth $1,009,836,250.

period,  Rafferty  waived its fees  and/or  absorbed  expenses in the amounts of
$92,798 and $50,746, respectively.

The Advisory  Agreement was approved by the Trustees  (including all Independent
Trustees) and Rafferty, 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
Rafferty or the Trust,  and (2) by the majority vote of either the full Board or
the  vote of a  majority  of the  outstanding  shares  of a Fund.  The  Advisory
Agreement  automatically  terminates on assignment and is terminable on 60 days'
written notice either by the Trust or Rafferty.

the Custodian holds and administers the assets in the Funds' portfolios.

DISTRIBUTOR

Rafferty Capital Markets,  Inc., 1311 Mamaroneck Avenue,  White Plains, New York
10605, serves as the distributor ("Distributor") in connection with the offering
of each Fund's shares on a no-load  basis.  The  Distributor  and  participating
dealers  with whom it has entered  into dealer  agreements  offer  shares of the
Funds as  agents  on a best  efforts  basis  and are not  obligated  to sell any
specific  amount of shares.  For the  fiscal  year ended  August 31,  1999,  the
Distributor  received  $33,385 as  compensation  from Rafferty for  distribution
services.

DISTRIBUTION PLANS

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  separate  plans for the
Investor Class ("Investor Class Plan"), the Advisor Class ("Advisor Class Plan")
and the Broker Class  ("Broker  Class Plan") of each Fund pursuant to which each
Fund may pay certain expenses incurred in the distribution of that Class' shares
and the  servicing  and  maintenance  of existing  Class  shareholder  accounts.
Pursuant  to each Plan,  a Fund may pay 1.00% of its  average  daily net assets.
However,  for the Investor Class Plan, the Board has authorized each Fund to pay
distribution and services fees only in an amount equal to the difference between
a Fund's total annual  operating  expenses  and the  contractual  limit on total
annual  operating  expenses  of 1.50% for the Plus Funds and 1.65% for the Short
Funds.

Each Plan was  approved  by the  Trustees  and the  Independent  Trustees of the
Funds.  In  approving  each  Plan,  the  Trustees  determined  that  there  is a

                                       30
<PAGE>

reasonable likelihood that the Plan will benefit each Fund and its shareholders.
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 OTC Plus  Fund and the  Small  Cap  Plus  Fund  paid  $45,604  and  $39,748,
respectively, in Investor Class 12b-1 fees for the fiscal year ending August 31,
1999. All of these fees were paid to the Advisor as compensation.

INDEPENDENT ACCOUNTANTS

PricewaterhouseCoopers  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

The net  asset  value per share of each  class of the  Funds  (except  the Money
Market Fund) is determined  separately  daily,  Monday through Friday, as of the
close of regular trading on the New York Stock Exchange  ("NYSE"),  each day the
NYSE is open for business.  The NYSE is not open on 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 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 designed to
stabilize the net asset value per share as computed for purposes of distribution
and  redemption.  The Board's  procedures  include  monitoring the  relationship
between the amortized cost value per share and a net asset value per share based
upon available  indications of market value. The Board will decide what, if any,
steps should be taken if there is a difference  of more than .5% between the two
methods.  The Board  will  take any steps  they  consider  appropriate  (such as
redemption in kind or shortening the average portfolio maturity) to minimize any
material  dilution or other unfair results arising from differences  between the
two methods of determining net asset value.

A security listed or traded on an exchange,  domestic or foreign,  or the Nasdaq
Stock  Market,  is valued at its last sales price on the  principal  exchange on

                                       31
<PAGE>

which it is  traded  prior to the time when  assets  are  valued.  If no sale is
reported  at that time, the mean of the last bid and asked prices 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.

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.

OTC  securities  held by a Fund will 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 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.  Dividend  income  and  other
distributions are recorded on 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.

                            PURCHASES AND REDEMPTIONS

RETIREMENT PLANS

Individuals who earn compensation and who have not reached age 70 1/2 before the
close of the year  generally  may  establish an  Individual  Retirement  Account
("IRA").  An  individual  may make  limited  contributions  to a IRA through the
purchase of shares of the Funds.  The Internal  Revenue Code of 1986, as amended
(the "Code"), limits the deductibility of IRA contributions to taxpayers who are
not active participants (and, under certain circumstances, whose spouses are not
active participants, unless their combined adjusted gross income does not exceed
$150,000)  in  employer-provided  retirement  plans or who have  adjusted  gross
income below certain levels. Nevertheless, the Code permits other individuals to
make  nondeductible  IRA contributions up to $2,000 per year (or $4,000, if such

                                       32
<PAGE>

contributions  also are made  for a  nonworking  spouse  and a joint  return  is
filed). In addition,  individuals  whose earnings  (together with their spouse's
earnings) do not exceed a certain level may establish an "education  IRA" and/or
a "Roth IRA"; although  contributions to these new types of IRAs (established by
the Taxpayer Relief Act of 1997) ("Tax Act") are nondeductible, withdrawals from
them will not be taxable under certain circumstances. A Heritage IRA also may be
used for certain  "rollovers"  from  qualified  benefit  plans and from  Section
403(b) annuity plans.

Fund  shares  also may be used as the  investment  medium  for  qualified  plans
(defined  benefit or defined  contribution  plans  established by  corporations,
partnerships or sole  proprietorships).  Contributions to qualified plans may be
made   (within   certain   limits)  on  behalf  of  the   employees,   including
owner-employees, of the sponsoring entity.


REDEMPTIONS BY TELEPHONE

Shareholders may redeem shares of the Funds by telephone.  When acting on verbal
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. In acting upon telephone instructions,  these parties use
procedures  that are reasonably  designed to ensure that such  instructions  are
genuine, such as (1) obtaining some or all of the following information: account
number,  name(s) and social security  number(s)  registered to the account,  and
personal  identification;  (2)  recording all  telephone  transactions;  and (3)
sending written confirmation of each transaction to the registered owner. 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.

REDEMPTION IN KIND

A Fund is obligated  to redeem  shares for any  shareholder  for cash during any
90-day period up to $250,000 or 1% of that Fund's net asset value,  whichever is
less. Any redemption beyond this amount also will be in cash unless the Trustees
determine  that further cash  payments  will have a material  adverse  effect on
remaining shareholders.  In such a case, a Fund will pay all or a portion of the
remainder of the redemption in portfolio instruments,  valued in the same way as
each fund determines net asset value. The portfolio instruments will be selected
in a manner that the Trustees deem fair and  equitable.  A redemption in kind is
not as  liquid  as a cash  redemption.  If a  redemption  is  made  in  kind,  a
shareholder   receiving  portfolio  instruments  could  receive  less  than  the
redemption value thereof and could incur certain transaction costs.

RECEIVING PAYMENT

Payment of redemption proceeds will be made within seven days following a Fund's
receipt of your  request  (if  received  in good order as  described  below) 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.


                                       33
<PAGE>

     A redemption request will be considered  to be received in "good order" if:

o    the number or amount of shares and the class of shares to be  redeemed  and
     shareholder account number have been indicated;
o    any written  request is signed by a shareholder and by all co-owners of the
     account  with  exactly  the same  name or names  used in  establishing  the
     account;
o    any written request is accompanied by certificates  representing the shares
     that have been issued,  if any, and the certificates have been endorsed for
     transfer  exactly  as the name or names  appear on the  certificates  or an
     accompanying stock power has been attached; and
o    the signatures on any written redemption request of $100,000 or more and on
     any  certificates  for shares (or an  accompanying  stock  power) have been
     guaranteed by a national  bank, a state bank that is insured by the Federal
     Deposit Insurance Corporation, a trust company or by any member firm of the
     New  York,  American,   Boston,  Chicago,  Pacific  or  Philadelphia  Stock
     Exchanges.  Signature  guarantees  also will be accepted from savings banks
     and certain  other  financial  institutions  that are deemed  acceptable by
     Firstar Mutual Funds Services,  LLC, as transfer  agent,  under its current
     signature guarantee program.

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,  the CBOE,  as  appropriate,  is  restricted.  In  addition,  the rights of
redemption may be suspended or the date of payment  postponed for any Fund for a
period  during  which  an  emergency  exists  so  that  disposal  of the  Fund's
investments  or the  determination  of its net  asset  value  is not  reasonably
practicable or for such periods as the SEC, by order,  may permit for protection
of a Fund's investors.


                               EXCHANGE PRIVILEGE

An exchange  is  effected  through the  redemption  of the shares  tendered  for
exchange and the purchase of shares being acquired at their respective net asset
values as next determined  following  receipt by the Fund whose shares are being
exchanged of (1) proper instructions and all necessary  supporting  documents or
(2) a telephone  request for such exchange in accordance with the procedures set
forth in the Prospectus and below.  Telephone  requests for an exchange received
by a Fund before the close of regular  trading on the Exchange  will be effected
at the close of regular trading on that day.  Requests for an exchange  received
after the close of regular  trading  will be  effected  on the  Exchange's  next
trading  day.  Due to the  volume  of  calls  or  other  unusual  circumstances,
telephone  exchanges may be difficult to implement  during certain time periods.

The Trust  reserves the right to reject any order to acquire its shares  through
exchange or  otherwise to restrict or  terminate  the exchange  privilege at any
time. In addition, the Trust may terminate this exchange privilege upon 60 days'
notice.


                        CONVERSION OF BROKER CLASS SHARES

Broker Class shares of the Funds  automatically  will convert to Investor  Class
shares,  based on the  relative  net asset  values per share of the two classes,

                                       34
<PAGE>

eight years after the end of the calendar month in which the shareholder's order
to purchase was  accepted.  For the purpose of  calculating  the holding  period
required for  conversion  of Broker Class shares,  the date of initial  issuance
shall mean (i) the date on which the Broker Class shares were issued or (ii) for
Broker Class shares obtained through an exchange, or a series of exchanges,  the
date on which the original  Broker  Class  shares were  issued.  For purposes of
conversion to Investor Class shares,  Broker Class shares purchased  through the
reinvestment  of  dividends  and other  distributions  paid in respect of Broker
Class shares will be held in a separate sub-account.  Each time any Broker Class
shares  in  the   shareholder's   regular  account  (other  than  those  in  the
sub-account)  convert to Investor Class shares, a pro rata portion of the Broker
Class shares in the sub-account will also convert to Investor Class shares.  The
portion  will be  determined  by the ratio that the  shareholder's  Broker Class
shares  converting  to Investor  Class shares bears to the  shareholder's  total
Broker Class shares not acquired through dividends and other distributions.

The  availability  of the  conversion  feature  is  subject  to  the  continuing
availability of an opinion of counsel to the effect that the dividends and other
distributions  paid on Investor  Class  shares and Broker  Class shares will not
result in  "preferential  dividends" under the Code and the conversion of shares
does not  constitute a taxable  event.  If the  conversion  feature ceased to be
available,  the Broker Class shares would not be converted and would continue to
be subject to the higher  ongoing  expenses of the Broker  Class  shares  beyond
eight years from the date of purchase. The Adviser has no reason to believe that
this condition for the availability of the conversion feature will not be met.


                             PERFORMANCE INFORMATION

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

COMPARATIVE INFORMATION

From time to time, each Fund's performance may be compared with recognized stock
and  other  indices,  such  as the  Standard  &  Poor's  Composite  Stock  Price
Index(TRADEMARK)    ("S&P    500    Index"),    the   Dow    Jones    Industrial
Average(SERVICEMARK)  ("DJIA"), the Nasdaq 100 Stock  Index(TRADEMARK)  ("Nasdaq
Index"), the Nasdaq Composite Index(TRADEMARK) ("Nasdaq Composite"),  the Nikkei
225 Stock Average ("Nikkei Index"), the Russell 2000 Index ("Russell 2000"), Dow
Jones Composite Internet Index(SERVICEMARK) ("Internet Index") and various other
domestic, international or 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

                                       35
<PAGE>

regard  to  tax  consequences  or  operating  expenses.   The  Nasdaq  Composite
comparison  may be provided to show how the  OTC/Plus 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/Plus 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/Plus 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.
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:

                                         n
                                   P(1+T) =ERV

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

Under the foregoing formula,  the time periods used in advertising will be based
on rolling calendar quarters, updated to the last day of the most recent quarter
prior to submission of the advertising for publication,  and will cover 1, 5 and
10 year periods or a shorter  period  dating from the  commencement  of a Fund's
operations.  In  calculating  the ending  redeemable  value,  all  dividends and
distributions  by a Fund are assumed to have been  reinvested at net asset value
on the reinvestment  dates during the period.  Additionally,  in calculating the
ending redeemable value for the Broker Class shares, the applicable CDSC will be
deducted.  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

                                       36
<PAGE>

data  published  by Lipper or with  market  indices,  each 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.

The performance provided represents historical  performance for the Funds listed

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,

                                       37
<PAGE>

exclusive  of capital  changes  and  including  the value of  additional  shares
purchased with  dividends and any dividends  declared  therefrom  (which reflect
deductions of all expenses of the Fund such as advisory fees), in the value of a
hypothetical  preexisting account having a balance of one share at the beginning
of the period,  subtracting a hypothetical  charge  reflecting  deductions  from
shareholder accounts, and dividing the difference by the value of the account at
the  beginning  of the base  period to obtain the base period  return,  and then
multiplying the base period return by (365/7).

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

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

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

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

The 7-day current yield for the Money Market Fund's  Investor Class as of August
31, 1999 is 4.18%.

                        SHAREHOLDER AND OTHER INFORMATION

SHAREHOLDER INFORMATION

Each share of a Fund gives the  shareholder  one vote in  matters  submitted  to
shareholders  for a vote.  Each  class of each Fund have  equal  voting  rights,
except that, in matters affecting only a particular class or series, only shares
of that  class or series  are  entitled  to vote.  Share  voting  rights are not
cumulative,  and shares have no preemptive or conversion  rights.  Share are not
transferable.  As a Massachusetts  business trust,  the Trust is not required to
hold annual shareholder  meetings.  Shareholder approval will be sought only for
certain  changes  in a Trust's or a Fund's  operation  and for the  election  of
Trustees under certain circumstances. Trustees may be removed by the Trustees or
by shareholders at a special meeting. A special meeting of shareholders shall be
called by the Trustees upon the written request of shareholders  owning at least
10% of a Trust's outstanding shares.

                    DIVIDENDS, OTHER DISTRIBUTIONS AND TAXES

DIVIDENDS AND OTHER DISTRIBUTIONS

Dividends  from net  investment  income and any  distributions  of realized  net
capital  gains are as  described  in the  Prospectus  under  "Distributions  and
Taxes." All  distributions  from a Fund  normally are  automatically  reinvested
without charge in additional shares of that Fund.

The Money Market Fund  ordinarily  declares  dividends daily from net investment
income and distributes such dividends monthly.  Net investment income, for these
purposes,  includes  accrued interest and accretion of original issue and market
discounts,  less amortization of market premium and estimated  expenses,  and is
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.  Each  Fund  is  treated  as a  separate
corporation  for  Federal  income tax  purposes  and will seek to or continue to
qualify as a regulated  investment  company  ("RIC")  under  Subchapter M of the
Internal  Revenue Code of 1986, as amended  ("Code").  Because of the investment
strategies  of each Fund  other  than the  Money  Market  Fund,  there can be no
assurance  that any such Fund will qualify as a RIC. If a Fund so qualifies  and
satisfies the  distribution  requirement  under the Code for a taxable year, the
Fund will not be  subject to  Federal  income tax on the part of its  investment

                                       39
<PAGE>

company taxable income  (generally  consisting of net investment  income and net
short-term  capital  gains) 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 for treatment as a RIC under the 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 and net short-term
capital  gain)  ("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 other income  (including gains
from  options or futures)  derived  with respect to its business of investing in
securities ("Income  Requirement");  and (2) at the close of each quarter of the
Fund's  taxable year,  (i) at least 50% of the value of its total assets must be
represented by cash and cash items, U.S.  Government  Securities,  securities of
other RICs,  and other  securities,  with those  other  securities  limited,  in
respect of any one issuer,  to an amount that does not exceed 5% of the value of
the  Fund's  total  assets  and that  does not  represent  more  than 10% of the
issuer's outstanding voting securities,  and (ii) not more than 25% of the value
of its total assets may be invested in  securities  (other than U.S.  Government
Securities  or the  securities  of other RICs) of any one issuer  (collectively,
"Diversification Requirements").

Although  each Fund intends to satisfy or continue 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 those  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 might
apply a different method resulting in  disqualification  of one or more of those
Funds.

By qualifying for treatment as a RIC, a Fund (but not its shareholders)  will be
relieved of Federal  income tax on the part of its  investment  company  taxable
income and net capital gain that it distributes to its  shareholders.  If a Fund
failed to qualify as a RIC for any taxable  year,  it would be taxed on the full
amount of its  taxable  income  for that year  without  being able to deduct the
distributions it makes to its shareholders and the shareholders  would treat all
those distributions,  including  distributions of net capital gain, as dividends
(that is, ordinary income) to the extent of the Fund's earnings and profits.

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.


                                       40
<PAGE>

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.

Dividends  distributed by the Fund  (including  distributions  of net short-term
capital gain),  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 (i.e., the excess of net long-term gain over net short-term capital
loss),  if any,  are taxable to its  shareholders  as long-term  capital  gains,
regardless  of how long  they  have held  their  Fund  shares  and  whether  the
distributions are reinvested in Fund shares or received in cash. A shareholder's
sale  (redemption)  of Fund shares may result in a taxable  gain,  depending  on
whether the redemption proceeds are more or less than the adjusted basis for the
shares.  An exchange of Fund shares for shares of another portfolio of the Trust
generally will have similar consequences.

INCOME FROM FOREIGN  SECURITIES.  Dividends and interest  received by a Fund and
gains  realized by 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.

A Fund  may  invest  in the  stock of  "passive  foreign  investment  companies"
("PFICs").  A PFIC is any foreign corporation (with certain exceptions) 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,  a
Fund  will  be  subject  to  Federal  income  tax on a  portion  of any  "excess
distribution"  received on the stock of a PFIC or of any gain on  disposition of
the stock (collectively, "PFIC income"), plus interest thereon, even if the Fund
distributes  the PFIC  income as a taxable  dividend  to its  shareholders.  The
balance of the PFIC income will be  included  in the Fund's  investment  company
taxable  income and,  accordingly,  will not be taxable to it to the extent that
income is  distributed  to its  shareholders.  If the Fund invests in a PFIC and
elects to treat the PFIC as a "qualified  electing fund" ("QEF"),  then, in lieu
of the  foregoing  tax and  interest  obligation,  the Fund would be required to
include  in income  each year its PRO RATA  share of the QEF's  annual  ordinary
earnings and net capital gain -- which  probably would have to be distributed by
the Fund to satisfy the  Distribution  Requirement  and avoid  imposition of the
Excise Tax -- even if those earnings and gain were not received by the Fund from
the QEF. In most instances it will be very difficult, if not impossible, to make
this election because of certain requirements thereof.

A 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 under the election (and under  regulations  proposed in 1992 that
provided a similar  election  with respect to the stock of certain  PFICs).  The
Fund's adjusted basis in each PFIC's stock with respect to which it makes

                                       41
<PAGE>

this  election  would be adjusted to reflect the amounts of income  included and
deductions taken under the election.

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

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

                                       42
<PAGE>

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.

If a Fund has an  "appreciated  financial  position" --  generally,  an interest
(including an interest through an option,  futures contract, or short sale) with
respect  to  any  stock,  debt  instrument  (other  than  "straight  debt"),  or
partnership  interest the fair market value of which exceeds its adjusted  basis
- -- and  enters  into a  "constructive  sale" of the  position,  the Fund will be
treated as having  made an actual  sale  thereof,  with the result  that it will
recognize gain at that time. A constructive  sale generally  consists of a short
sale, an offsetting notional principal  contract,  or a futures contract entered
into by a Fund or a related  person  with  respect to the same or  substantially
identical property. In addition, if the appreciated financial position is itself
a short sale or such a  contract,  acquisition  of the  underlying  property  or
substantially  identical  property  will be  deemed  a  constructive  sale.  The
foregoing will not apply,  however,  to any transaction  during any taxable year
that  otherwise  would be treated as a constructive  sale if the  transaction is
closed  within  30 days  after  the end of that  year  and the  Fund  holds  the
appreciated financial position unhedged for 60 days after that closing (I.E., at
no time  during that 60-day  period is the Fund's  risk of loss  regarding  that
position  reduced by reason of certain  specified  transactions  with respect to
substantially  identical or related property,  such as having an option to sell,
being  contractually  obligated  to sell,  making a short  sale,  or granting an
option to buy substantially identical stock or securities).

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.

Item 25. Indemnification
         ---------------

         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

                                      C-2
<PAGE>

thereafter,  and the words  "liability"  and "expenses"  shall include,  without
limitation,  attorneys'  fees,  costs,  judgments,  amounts paid in  settlement,
fines, penalties and other liabilities.

         (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.



                                      C-3
<PAGE>

         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.

         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.

                                DEALER AGREEMENT



         This Agreement made as of  ___________________,  1999, between Rafferty
Capital Markets,  Inc. ("RCM"),  a corporation  organized and existing under the
laws  of  the  State  of  New  York,  and  _____________________  ("Dealer"),  a
corporation organized and existing under the laws of ________________.

         WHEREAS,  each fund listed on Schedule A (each a "Fund") is  registered
under the  Investment  Company  Act of 1940,  as  amended  ("1940  Act"),  as an
open-end management  investment company or a series thereof and currently offers
for public sale shares of common stock or beneficial interest ("Shares"),

         WHEREAS,  RCM serves as principal  underwriter  in connection  with the
offering  and  sale  of the  Shares  of each  Fund  pursuant  to a  Distribution
Agreement; and

         WHEREAS,  Dealer desires to serve as a selected  dealer for the Shares;
and

         NOW  THEREFORE,  in  consideration  of  the  promises  and  the  mutual
covenants contained herein, RCM and Dealer agree as follows:

         1.  OFFERS AND SALES OF SHARES.  The Dealer is to offer and sell Shares
only at the public  offering price  currently in effect,  in accordance with the
terms  of  the  then-current   prospectus(es),   including  any  supplements  or
amendments thereto, of each Fund  ("Prospectus").  The Dealer agrees to act only
as principal in such  transactions  and shall not have authority to act as agent
for the Funds, for RCM, or for any other dealer in any respect. Dealer agrees to
purchase Shares of the Funds only in transactions contemplating the simultaneous
resale of such Shares to investors and in no event shall Dealer place orders for
Shares unless it has already received customers orders to purchase Shares at the
applicable public offering price.  Unless otherwise  mutually agreed in writing,
each transaction shall be confirmed in writing.  All purchase orders are subject
to acceptance by RCM and the Fund and become effective only upon confirmation by
RCM.  In its sole  discretion,  either the Fund or RCM may  reject any  purchase
order and may, without notice,  suspend sales or withdraw the offering of Shares
entirely.

         2. PROCEDURES FOR PURCHASES.  The procedures relating to all orders and
the handling of them shall be made in accordance  with the  procedures set forth
in each Fund's  Prospectus,  and to the extent  consistent  with the Prospectus,
written instructions forwarded to Dealer by RCM from time to time.

         3. SETTLEMENT AND DELIVERY FOR PURCHASES. Transactions shall be settled
by the  Dealer by payment of the full  purchase  price to RCM in Federal  Funds.
Payment for Shares ordered from RCM shall be received by RCM by the later of (a)


<PAGE>

the  end of the  third  business  day  following  the  Dealer's  receipt  of the
customer's  order to  purchase  such Shares or (b) the end of one  business  day
following the Dealer's receipt of the customer's payment for such Shares, but in
no event later than the end of the sixth  business  day  following  the Dealer's
receipt of the customer's order. If such payment is not received within the time
specified,  the sale may be canceled  forthwith  without any  responsibility  or
liability  on RCM's  part or on the part of the Funds (in which  case the Dealer
will be  responsible  for any loss,  including  loss of profit,  suffered by the
Funds resulting from the Dealer's failure to make payment as aforesaid),  or, at
RCM's option,  RCM may sell the Shares  ordered back to the Funds (in which case
RCM may hold the  Dealer  responsible  for any loss of  profit  suffered  by RCM
resulting from the Dealer's failure to make payment as aforesaid).

         RCM will not accept from the Dealer any conditional  orders for Shares.
Delivery of certificates for Shares purchased shall be made by the Funds only if
requested (provided that the Fund issues  certificates) and only against receipt
of the purchase  price,  subject to deduction for any discount  reallowed to the
Dealer and RCM's portion of the sales charge on such sale.

         RCM shall pay to the Dealer,  not less  frequently  than  monthly,  the
aggregate  fees  due it on  orders  received  and  settled.

         4. PROCEDURES FOR REDEMPTIONS, REPURCHASES AND EXCHANGES. Redemption or
repurchases  of Shares as well as exchange  requests shall be made in accordance
with the procedures set forth in the each Fund's  Prospectus,  and to the extent
consistent with the Prospectus,  written instructions forwarded to Dealer by RCM
from time to time.

         5. COMPENSATION. On each purchase of Shares by the Dealer from RCM, the
total sales charges and discount to selected dealer,  if any, shall be as stated
in each  Fund's  Prospectus.  Such sales  charges and  discounts  to dealers are
subject to  reductions  under a variety of  circumstances  as  described in each
Fund's Prospectus. To obtain these reductions,  RCM must be notified when a sale
takes place that would qualify for the reduced charge. If any Shares sold to the
Dealer under the terms of this  Agreement are redeemed by a Fund or  repurchased
within seven  business days after the date of the Dealer  purchased such Shares,
the Dealer agrees to forfeit its right to any discount or commission received by
or allowed to the Dealer from the original sale.

         From  time to time  during  the  term of this  Agreement,  RCM may make
payments to Dealer pursuant to one or more distribution plans adopted by certain
of the Funds  pursuant to Rule 12b-1 under the 1940 Act ("Plan of  Distribution)
in   consideration,   with  respect  to  each  such  Fund,  of  your  furnishing
distribution  services  hereunder and providing  administrative,  accounting and
other services, including personal service and/or the maintenance of shareholder
accounts.  The  provisions  and  terms  of a  Fund's  Plan of  Distribution  are
described in its Prospectus and statement of additional information ("SAI"), and
the  Dealer  agrees  that RCM has made no  representations  to the  Dealer  with
respect to the Plan of  Distribution  in  addition  to or  conflicting  with the
description set forth therein. The Dealer agrees that (1) Dealer has no right to
receive  payment of any  amounts  otherwise  payable to it by RCM under a Fund's
Plan of  Distribution  until such time as RCM is in receipt of such fee from the
Fund and (2) RCM's  liability  to the Dealer for the payment of any such fees is


                                       2
<PAGE>

limited  solely to the amount of the  applicable  Fund's fee received by RCM.

         6. EXPENSES.  The Dealer agrees that it will bear all expenses incurred
in connection with its performance of this  Agreement.

         7. DEALER  REGISTRATION.  The Dealer represents and warrants that it is
registered as a  broker-dealer  under the  Securities  Exchange Act of 1934 (the
"1934  Act"),  is  qualified  as  a   broker-dealer   in  all  states  or  other
jurisdictions  in  which it sells  Fund  Shares,  and,  if it  sells  shares  in
additional  states or jurisdictions in the future,  will become qualified to act
as a dealer in each such state or jurisdiction prior to selling any Fund shares.
The Dealer shall maintain any filings and licenses required by federal and state
laws to conduct  the  business  contemplated  under this  Agreement.  The Dealer
further  represents  and  warrants  that it is a member in good  standing of the
National Association of Securities Dealers,  Inc. ("NASD") and that it agrees to
abide by the  Conduct  Rules of the  NASD.  The  Dealer  agrees  to  notify  RCM
immediately  in the event of (1) its expulsion or  suspension  from the NASD, or
(2) its being found to have violated any  applicable  federal or state law, rule
or regulation  arising out of its activities as a broker-dealer or in connection
with this  Agreement,  or which may  otherwise  affect in any  material  way its
ability  to act in  accordance  with the  terms of this  Agreement.  The  Dealer
further  represents and warrants that it is a member of the Securities  Investor
Protection Corporation ("SIPC") in good standing and agrees to notify RCM of any
changes in the Dealer's  status with the SIPC.

         8. COMPLIANCE WITH FEDERAL AND STATE LAWS. The Dealer will not offer or
sell any of the Shares  except in  compliance  with all  applicable  federal and
state securities  laws. In connection with sales and offers to sell Shares,  the
Dealer  will  furnish or cause to be  furnished  to each person to whom any such
sale or offer is made,  at or prior to the time of offering  or sale,  a copy of
the  Prospectus  and,  if  requested,  the  related  SAI.  RCM shall be under no
liability  to the  Dealer  except  for lack of good  faith  and for  obligations
expressly  assumed by RCM herein.  Nothing herein contained,  however,  shall be
deemed to be a condition, stipulation or provision binding any persons acquiring
any security to waive compliance with, or to relieve the parties hereto from any
liability arising under, the federal securities laws.

         RCM  shall,  from time to time,  inform the Dealer as to the states and
jurisdictions  in which RCM  believes  the Shares have been  qualified  for sale
under, or are exempt from the requirements of, the respective securities laws of
such states and jurisdictions.  The Dealer agrees that it will not offer or sell
Shares in any state or  jurisdiction  in which such  Shares  are not  qualified,
unless any such offer or sale is made in a  transaction  that  qualifies  for an
exemption from registration.

         RCM assumes no  responsibility  in connection with the  registration of
the Dealer  under the laws of the  various  states or under  federal  law or the
Dealer's qualification under any such law to offer or sell Shares.

         9.  UNAUTHORIZED  REPRESENTATIONS.  No person is authorized to make any
representations  concerning  Shares of the Funds except  those  contained in the
Prospectus,  SAI  and  printed  information  issued  by  each  Fund or by RCM as
information supplemental to each Prospectus. RCM shall, upon request, supply the

                                       3
<PAGE>

Dealer with reasonable  quantities of  Prospectuses  and SAIs. The Dealer agrees
not to use other  advertising  or sales  material  relating to the Funds  unless
approved in writing by RCM in advance of such use.

         Neither  party  shall  use the name of the  other  party in any  manner
without the other party's written consent,  except as required by any applicable
federal or state law, rule or  regulation,  and except  pursuant to any mutually
agreed upon promotional programs.

         10. CONFIRMATIONS. The Dealer agrees to send confirmations of orders to
its  customers  as required by Rule 10b-10 of the 1934 Act and agrees to pay any
costs in connection therewith.

         11.  RECORDS.  The Dealer  agrees to maintain  all records  required by
applicable state and federal laws and regulations relating to the offer and sale
of Shares,  and upon the  request of RCM, or of the Funds,  promptly  make these
records available to RCM or the Funds' Administrator as requested.  In addition,
the Dealer hereby agrees to establish appropriate procedures and reporting forms
and/or  mechanisms  and  schedules  in  conjunction  with  RCM  and  the  Funds'
Administrator,  to enable the Funds to identify the location, type of, and sales
to all accounts opened and maintained by the Dealer's customers or by the Dealer
on behalf of the Dealer's customers.

         12. TAXPAYER  IDENTIFICATION  NUMBERS.  The Dealer agrees to obtain any
taxpayer  identification  number certification from its customers required under
the  Internal  Revenue  Code and any  applicable  Treasury  regulations,  and to
provide RCM or its designee with timely  written notice of any failure to obtain
such  taxpayer  identification  number  certification  in  order to  enable  the
implementation of any required backup withholding.

         13.  INDEMNIFICATION.  (a) The Dealer shall indemnify and hold harmless
RCM,  each  Fund,  the  transfer  agents  of the  Funds,  and  their  respective
affiliates,  officers, directors, agents, employees and controlling persons from
all direct or indirect  liabilities,  losses or costs (including attorneys fees)
arising from, related to or otherwise connected with:

         (1) any breach by the Dealer of any provision of this Agreement; or

         (2) any actions or omissions of RCM, any Fund,  the transfer  agents of
     the Funds, and the subsidiaries,  affiliates,  officers, directors, agents,
     employees and controlling persons of any of them, in reliance upon any oral
     or written instructions believed to be genuine and to have been given by or
     on behalf of the Dealer.

         (b)  RCM  shall   indemnify  and  hold  harmless  the  Dealer  and  its
affiliates,  officers, directors, agents, employees and controlling persons from
and  against  any and all  direct  or  indirect  liabilities,  losses  or  costs
(including attorneys fees) arising from, related to or otherwise connected with:

         (1) any breach by RCM of any provision of this Agreement; or

         (2) any alleged  untrue  statement of a material fact  contained in any
     Fund's  Registration   Statement  or  prospectus  or  in  any  supplemental

                                       4
<PAGE>

     materials  prepared  by RCM and  supplied  to the  Dealer,  or any  alleged
     omission  to state in any such  document a  material  fact  required  to be
     stated, or necessary to make the statements made not misleading,  but only,
     in the case of a Registration Statement or Prospectus, if such statement or
     omission was made by the Fund in reliance on information provided by RCM.

         (c) The  Agreement of the parties in this  Paragraph to indemnify  each
other is  conditioned  upon the party entitled to  indemnification  (Indemnified
Party)  giving  notice to the party  required  to  provide  the  indemnification
(Indemnifying Party) promptly after the summons or other first legal process for
any claim as to which  indemnity  may be  sought  is  served on the  Indemnified
Party. The Indemnified  Party shall permit the Indemnifying  Party to assume the
defense of any such claim or any  litigation  resulting  from it,  provided that
counsel for the  Indemnifying  Party who shall conduct the defense of such claim
or litigation  shall be approved by the Indemnified  Party (which approval shall
not unreasonably be withheld), and that the Indemnified Party may participate in
such defense at its expense. The failure of the Indemnified Party to give notice
as provided in this  sub-paragraph (c) shall not relieve the Indemnifying  Party
from any liability other than its indemnity obligation under this Paragraph.  No
Indemnifying  Party,  in the  defense  of any such claim or  litigation,  shall,
without the consent of the Indemnified  Party,  consent to entry of any judgment
or enter into any settlement that does not include as an unconditional  term the
giving by the claimant or plaintiff to the  Indemnified  Party of a release from
all liability in respect to such claim or litigation.

         14. NO AGENCY  CREATED.  Nothing in this  Agreement  shall be deemed or
construed to make the Dealer an employee,  agent,  representative  or partner of
any of the Funds or of RCM, and the Dealer is not  authorized  to act for RCM or
for any Fund or to make any  representations  on RCM's or the Funds' behalf. The
Dealer  acknowledges that this Agreement is not exclusive and that RCM may enter
into similar arrangements with other broker-dealers.

         15.  TERMINATION,  ASSIGNMENT  AND  AMENDMENT.  Either  party  to  this
Agreement may cancel this  Agreement by giving ten days'  written  notice to the
other.  Such  notice  shall be deemed to have been given on the date on which it
was either  delivered  personally  to the other  party or any  officer or member
thereof or was mailed to the other  party at its  address as shown  below.  This
Agreement will terminate  automatically  without notice with respect to any Fund
if (a) the Dealer filed a petition in  bankruptcy,  (b) a trustee or the like is
appointed for the Dealer or its assets under federal  bankruptcy  laws,  (c) the
Dealer's  registration  as a  broker-dealer  with the  Securities  and  Exchange
Commission  is  suspended  or  revoked,  (d) the  Dealer's  NASD  membership  is
suspended or revoked,  (e) if an application  for a protective  decree under the
provisions of the  Securities  Investor  Protection  Act of 1970 shall have been
filed against the Dealer,  or (f) the Distribution  Agreement  between RCM and a
Fund is  terminated.  Termination of this Agreement by operation of this Section
15 shall not affect  any unpaid  obligations  under  Sections  2, 3 or 5 of this
Agreement or the  liability,  legal and  indemnity  obligations  set forth under
Sections 7, 8, 9, or 13 of this Agreement.  This Agreement may be amended by RCM
at any time upon  notice  thereof to the Dealer and the  Dealer's  placing of an
order  after the  effective  date of any such  amendment  shall  constitute  the
Dealer's  acceptance  thereof.

Potomac Funds
1311 Mamaroneck Avenue
White Plains, New York 10605

Ladies and Gentlemen:

         You have  requested  our  opinion,  as counsel  to  Potomac  Funds (the
"Trust"),  as to certain matters  regarding the issuance of Shares of the Trust.
As used in this letter,  the term  "Shares"  means the Investor  Class,  Advisor
Class and Broker Class shares of beneficial  interest of the following series of
the Trust:  Potomac U.S. Plus Fund;  Potomac  U.S./Short Fund;  Potomac OTC Plus
Fund;  Potomac  OTC/Short Fund;  Potomac Dow 30 Plus Fund;  Potomac Dow 30/Short
Fund;  Potomac  Small Cap Plus  Fund;  Potomac  Small  Cap/Short  Fund;  Potomac
Internet  Plus  Fund;  Potomac  Internet/Short  Fund;  Potomac  Japan Plus Fund;
Potomac Japan/Short Fund and Potomac U.S. Government Money Market Fund.

         As such counsel,  we have examined certified or other copies,  believed
by us to be genuine,  of the Trust's  Declaration  of Trust and by-laws and such
resolutions  and minutes of meetings of the Trust's Board of Trustees as we have
deemed relevant to our opinion,  as set forth herein.  Our opinion is limited to
the laws and facts in existence on the date hereof, and it is further limited to
the  laws  (other  than  the  conflict  of law  rules)  in the  Commonwealth  of
Massachusetts that in our experience are normally  applicable to the issuance of
shares by  unincorporated  voluntary  associations  and to the Securities Act of
1933 ("1933  Act"),  the  Investment  Company  Act of 1940 ("1940  Act") and the
regulations of the Securities and Exchange Commission ("SEC") thereunder.

         Based  on  present  laws  and  facts,  we are of the  opinion  that the
issuance of the Shares has been duly authorized by the Trust and that, when sold
in accordance with the terms contemplated by the Post-Effective  Amendment No. 5
to the Trust's Registration Statement on Form N-1A ("PEA"), including receipt by
the Trust of full  payment for the Shares and  compliance  with the 1933 Act and
the 1940  Act,  the  Shares  will  have  been  validly  issued,  fully  paid and
non-assessable.

         We note,  however,  that the Trust is an  entity  of the type  commonly
known as a "Massachusetts business trust." Under Massachusetts law, shareholders
could,  under  certain   circumstances,   be  held  personally  liable  for  the
obligations  of the Trust.  The  Declaration  of Trust  states  that all persons
extending  credit to,  contracting with or having any claim against the Trust or
the Trustees  shall look only to the assets of the Trust for payment  under such
credit,  contract or claim; and neither the  Shareholders nor the Trustees,  nor
any of their agents, whether past, present or future, shall be personally liable
therefor.  It also requires that every note, bond, contract or other undertaking
issued by or on behalf of the Trust or the Trustees  relating to the Trust shall

<PAGE>

Page 2


include a recitation  limiting the obligation  represented  thereby to the Trust
and  its  assets.   The   Declaration  of  Trust  further   provides:   (1)  for
indemnification  from the  assets of the Trust for all loss and  expense  of any
shareholder held personally liable for the obligations of the Trust by virtue of
ownership of shares of the Trust; and (2) for the Trust to assume the defense of
any claim against the shareholder for any act or obligation of the Trust.  Thus,
the risk of a shareholder  incurring  financial  loss on account of  shareholder
liability  is limited  to  circumstances  in which the Trust or series  would be
unable to meet its obligations.

         We hereby consent to this opinion accompanying the PEA when it is filed
with the SEC and to the reference to our firm in the PEA.

                                         Very truly yours,

                                         KIRKPATRICK & LOCKHART LLP

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 an Investor Class 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 Investor  Class  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, with respect to its Portfolios' Investor Class
shares,  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.

      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.


<PAGE>

      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.

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

                                  POTOMAC FUNDS

                   MULTIPLE CLASS PLAN PURSUANT TO RULE 18F-3

         The Potomac Funds (the "Trust")  hereby adopt this Multiple  Class Plan
pursuant to Rule 18f-3 under the Investment Company Act of 1940, as amended (the
"1940 Act").

A.       CLASSES OFFERED

         Each  series of the Trust  (each,  a "Fund")  offers  three  classes of
shares pursuant to this Multiple Class Plan. The classes are described below and
require an initial investment of $10,000, except for certain retirement accounts
and investment plans for which lower limits may apply.

         1. INVESTOR  CLASS.  Investor  Class shares are offered for purchase to
investors  directly  from each series of the Trust  (each,  a "Fund").  Investor
Class  shares will be sold without any sales  charges,  but will be subject to a
Rule 12b-1 fee at an annual rate of up to 1.00% of its average  daily net assets
attributable to Investor Class shares,  0.75% of which represents an asset-based
sales charge and 0.25% of which  represents  a service  fee.  These are the same
fees  as are  provided  for in the  existing  Distribution  Plan.  The  existing
Distribution Plan will become the Investor Class Distribution Plan.

         2.  ADVISOR  CLASS.  Advisor  Class  shares  will be sold only  through
investment advisers, banks, trust companies or other authorized  representatives
who have  entered  into an  agreement  with the Trust.  There will be no initial
sales  charge or  contingent  deferred  sales charge  ("CDSC") on Advisor  Class
purchases. Advisor Class shares generally will pay Rule 12b-1 fees at the annual
rate of up to 1.00% of a Fund's average daily net assets attributable to Advisor
Class shares, 0.75% of which represents an asset-based sales charge and 0.25% of
which represents a service fee.

         3. BROKER CLASS.  Broker Class shares will be sold through  brokers and
dealers.  Broker Class shares are subject to a CDSC that  declines in steps from
5.0% to zero during a six-year  period.  The CDSC applied to redemptions  within
the first six years  will be the lower of (1) the net asset  value of the shares
at the time of  purchase or (2) the net asset value of the shares at the time of
redemption.  While  there  will be no  front-end  sales  charge on Broker  Class
purchases,  Broker  Class  shares  will likely bear a higher Rule 12b-1 fee than
Investor Class shares.  Broker Class shares  generally will pay a Rule 12b-1 fee
at the annual rate of up to 1.00% of its average  daily net assets  attributable
to Broker Class shares,  0.75% of which  represents an asset-based  sales charge
and 0.25% of which represents a service fee. Eight years after purchase,  Broker
Class shares will convert  automatically to Advisor Class shares at relative net
asset value.

B.       EXPENSE ALLOCATIONS OF EACH CLASS

         Certain expenses may be attributable to a particular class of shares of
a Fund ("Class Expenses"). Class Expenses are charged directly to the net assets
of the  particular  class  and,  thus  are  borne  on a pro  rata  basis  by the
outstanding shares of that class.


<PAGE>

         Each class may pay a different  amount of the following other expenses:
(1)  distribution  and service fees, (2) transfer agent fees identified as being
attributable  to a  specific  class,  (3)  stationery,  printing,  postage,  and
delivery  expenses  related to  preparing  and  distributing  materials  such as
shareholder reports,  prospectuses, and proxy statements to current shareholders
of a class,  (4) Blue Sky  registration  fees  incurred  by a specific  class of
shares, (5) Securities and Exchange  Commission  registration fees incurred by a
