                       STATEMENT OF ADDITIONAL INFORMATION

                        7900 WISCONSIN AVENUE, SUITE 300
                            BETHESDA, MARYLAND 20814

     This statement of additional  information  describes  nine  ProFunds.  Each
ProFund offers two classes of shares:  Service Shares and Investor  Shares.  The
ProFunds may be used by professional  money managers and investors as part of an
asset-allocation  or  market-timing  investment  strategy or to create specified
investment exposure to a particular segment of the securities market or to hedge
an existing investment portfolio. Sales are made without any sales charge at net
asset  value.  Each  non-money-market  ProFund  seeks  investment  results  that
correspond  each  day  to a  specified  benchmark.  The  ProFunds  may  be  used
independently or in combination with each other as part of an overall investment
strategy. Additional ProFunds may be created from time to time.

     The ProFunds  include the Money Market  ProFund.  The Money Market  ProFund
seeks  a high  level  of  current  income  consistent  with  liquidity  and  the
preservation  of  capital  through  investment  in  high  quality  money  market
instruments.  Unlike  other mutual  funds,  the Money  Market  ProFund  seeks to
achieve its investment  objective by investing all of its  investable  assets in
the Cash Management  Portfolio (the "Portfolio"),  a separate investment company
with an identical  investment  objective.  The  performance  of the Money Market
ProFund will correspond directly to the investment performance of the Portfolio.

     The ProFunds involve special risks, some not traditionally  associated with
mutual funds.  Investors  should  carefully  review and evaluate  these risks in
considering an investment in the ProFunds to determine  whether an investment in
a particular  ProFund is appropriate.  None of the ProFunds alone  constitutes a
balanced  investment  plan.  Each  non-money  market Profund is not intended for
investors  whose  principal  objective  is  current  income or  preservation  of
capital.  Because  of the  inherent  risks in any  investment,  there  can be no
assurance that the ProFunds' investment objectives will be achieved.

     This Statement of Additional Information is not a prospectus.  It should be
read  in  conjunction  with  ProFunds'  Prospectus,  dated  May 1,  1999,  which
incorporates  this  Statement  of  Additional  Information  by  reference.   The
financial statements and related report of the independent  accountants included
in the Fund's  annual  report for the fiscal  year ended  December  31, 1998 are
incorporated by reference into this Statement of Additional Information.  A copy
of the Prospectus or Annual Report is available, without charge, upon request to
the address above or by telephoning at the telephone numbers above.


     The  date  of this  Statement  of  Additional  Information  is May 1,  1999
(revised October 19, 1999)

     ProFunds (the "Trust") is an open-end management  investment  company,  and
currently  comprises  nine  separate  series.  Other  series may be added in the
future. The ProFunds may be used independently or in combination with each other
as  part  of an  overall  investment  strategy.  Shares  of any  ProFund  may be
exchanged, without any charge, for shares of the same class of any other ProFund
on the  basis  of the  respective  net  asset  values  of the  shares  involved;
provided,  that, in connection with exchanges for shares of the ProFund, certain
minimum  investment  levels  are  maintained  (see  "Shareholders   Services  --
Exchanges " in the Prospectus).


                       INVESTMENT POLICIES AND TECHNIQUES

GENERAL

     Reference is made to the sections entitled "Specific ProFunds  Objectives",
"Strategy",  "Risks in Common" and  "Considering  a ProFunds  Investment" in the
ProFund's Prospectus for a discussion of the investment  objectives and policies
of the ProFunds. In addition, set forth below is further information relating to
the ProFunds. The discussion below supplements and should be read in conjunction
with the Prospectus.  Portfolio  management is provided to the non-money  market
ProFunds by its investment  adviser,  ProFund  Advisors LLC, a Maryland  limited
liability company with offices at 7900 Wisconsin Avenue, NW, Bethesda,  Maryland
(the  "Advisor").  The Money  Market  ProFund  seeks to achieve  its  investment
objective  by  investing  all of its  assets in the  Portfolio  which has as its
investment adviser, Bankers Trust Company ("Bankers Trust").

     The investment objectives (except the specific benchmarks which are tracked
by  the  ProFunds)  and  certain   investment   restrictions   of  the  ProFunds
specifically  identified as fundamental  policies may not be changed without the
affirmative  vote of at least the  majority  of the  outstanding  shares of that
ProFund,  as  defined  in the 1940 Act.  All other  investment  policies  of the
ProFunds not specified as fundamental (including the benchmarks of the ProFunds)
may be  changed  by the  trustees  of  the  ProFunds  without  the  approval  of
shareholders.

     The non-money market ProFunds may consider  changing a ProFund's  benchmark
if, for example, the current benchmark becomes unavailable; the ProFunds believe
the current  benchmark no longer  serves the  investment  needs of a majority of
shareholders or another benchmark better serves their needs; or the financial or
economic  environment makes it difficult for the ProFund's investment results to
correspond sufficiently to its current benchmark.  If believed appropriate,  the
ProFunds  may  specify  a  benchmark  for  a  ProFund  that  is  "leveraged"  or
proprietary.  Of course,  there can be no assurance  that a ProFund will achieve
its objective.

     Fundamental  securities  analysis is not  generally  used by the Advisor in
seeking  to  correlate  with the  respective  benchmarks.  Rather,  the  Advisor
primarily  uses   statistical  and   quantitative   analysis  to  determine  the
investments a non-money  market ProFund makes and  techniques it employs.  While
the Advisor attempts to minimize any "tracking error" (that statistical  measure
of  the  difference  between  the  investment  results  of  a  ProFund  and  the
performance of its  benchmark),  certain  factors will tend to cause a ProFund's
investment  results to vary from a perfect  correlation  to its  benchmark.  The
ProFunds,  however,  do not expect that their total returns will vary  adversely
from their  respective  current  benchmarks  by more than ten  percent  over the
course of a year. See "Special Considerations."

     It  is  the  policy  of  the  non-money-market  ProFunds  to  pursue  their
investment  objectives of correlating with their benchmarks regardless of market
conditions, to remain nearly fully invested and not to take defensive positions.

     The investment strategies of the ProFunds discussed below, and as discussed
in the  Prospectus,  may be used by a ProFund if, in the opinion of the Advisor,
these  strategies will be  advantageous  to the ProFund.  The ProFund is free to
reduce  or  eliminate  the  ProFund's  activity  in any of those  areas  without
changing the ProFund's  fundamental  investment policies.  There is no assurance
that any of these  strategies or any other  strategies and methods of investment
available  to a  ProFund  will  result  in  the  achievement  of  the  ProFund's
objectives.

THE BULL PROFUND AND ULTRABULL PROFUND

     The  investment  objective  of the Bull  ProFund is to  provide  investment
returns that correspond to the performance of the S&P 500 Index.  The investment
objective  of the  UltraBull  ProFund  is to  provide  investment  returns  that
correspond to 200% of the performance of the S&P 500 Index.  These ProFunds seek
to  achieve  this  correlation  on each  trading  day.  Under  their  investment
objectives, the UltraBull ProFund should produce greater gains to investors when
the S&P 500 Index rises and greater  losses when the S&P 500 Index declines over
the corresponding gain or loss of the Bull ProFund.

     In  attempting  to  achieve  their  objectives,  the Bull  ProFund  and the
UltraBull  ProFund expect that a substantial  portion of their respective assets
usually will be devoted to employing certain specialized  investment techniques.
These techniques include engaging in certain transactions in stock index futures
contracts,  options on stock index futures contracts,  and options on securities
and stock indexes. The amount of any gain or loss on an investment technique may
be affected by any premium or amounts in lieu of  dividends  or interest  income
the ProFund pays or receives as the result of the  transaction.  These  ProFunds
may also invest in shares of individual  securities  which are expected to track
the S&P 500 Index.

THE BEAR PROFUND AND ULTRABEAR PROFUND

     The Bear ProFund and the UltraBear  ProFund are designed to allow investors
to  speculate  on  anticipated  decreases  in the S&P 500  Index  or to hedge an
existing  portfolio  of  securities  or mutual fund shares.  The Bear  ProFund's
investment  objective  is to  provide  investment  results  that will  inversely
correlate  to the  performance  of the S&P 500 Index.  The  UltraBear  ProFund's
investment  objective  is to  provide  investment  results  that will  inversely
correlate to 200% of the  performance of the S&P 500 Index.  These ProFunds seek
to achieve this inverse correlation on each trading day.

     If the Bear ProFund  achieved a perfect inverse  correlation for any single
trading  day,  the net  asset  value of the  shares  of the Bear  ProFund  would
increase for that day in direct  proportion  to any decrease in the level of the
S&P 500 Index. Conversely, the net asset value of the shares of the Bear ProFund
would decrease for that day in direct proportion to any increase in the level of
the S&P 500 Index for that day. The net asset value of the UltraBear  ProFund on
the same days would  increase  or  decrease  approximately  twice as much as the
price change of the Bear ProFund.

     For  example,  if the S&P 500 Index were to decrease by 1% on a  particular
day,  investors in the Bear ProFund should  experience a gain in net asset value
of  approximately  1% for that day.  The  UltraBear  ProFund  should  realize an
increase of approximately 2% of its net asset value on the same day. Conversely,
if the S&P 500  Index  were to  increase  by 1% by the  close of  business  on a
particular  trading day, investors in the Bear ProFund and the UltraBear ProFund
would  experience  a  loss  in net  asset  value  of  approximately  1% and  2%,
respectively.

     Due to the nature of the Bear ProFund and the UltraBear ProFund,  investors
in these ProFunds could experience  substantial  losses during sustained periods
of rising  equity  prices,  with losses to  investors in the  UltraBear  ProFund
approximately  twice as large as the losses to  investors  in the Bear  ProFund.
This is the opposite likely result expected of investing in a traditional equity
mutual fund in a generally rising stock market.

     In pursuing its investment  objectives,  the Bear ProFund and the UltraBear
ProFund generally do not invest in traditional securities,  such as common stock
of  operating  companies.  Rather,  the Bear ProFund and the  UltraBear  ProFund
employ certain investment  techniques,  including engaging in short sales and in
certain  transactions in stock index futures  contracts,  options on stock index
futures contracts, and options on securities and stock indexes.

     Under these  techniques,  the Bear ProFund and the  UltraBear  ProFund will
generally  incur  a loss  if the  price  of the  underlying  security  or  index
increases  between the date of the  employment  of the technique and the date on
which the ProFund terminates the position. These ProFunds will generally realize
a gain if the  underlying  security  or index  declines in price  between  those
dates. The amount of any gain or loss on an investment technique may be affected
by any premium or amounts in lieu of dividends or interest that the ProFund pays
or receives as the result of the transaction.

THE ULTRAOTC PROFUND AND THE ULTRASHORT OTC PROFUND

     The investment  objective of the UltraOTC ProFund is to provide  investment
results that correspond to 200% of the performance of the NASDAQ 100 IndexTM.

     The UltraOTC ProFund does not intend to hold the 100 securities included in
the NASDAQ 100  IndexTM.  Instead,  the  UltraOTC  ProFund  intends to engage in
transactions  on stock index futures  contracts,  options on stock index futures
contracts,  and options on securities  and stock  indexes.  As a  nonfundamental
policy, the UltraOTC ProFund will invest, under normal conditions,  at least 65%
of its total assets in  securities  traded on the  over-the-counter  markets and
instruments  with  values that are  representative  of such  securities  such as
futures and option contracts in such securities or indices.

     The  investment  objective  of the  UltraShort  OTC  ProFund  is to provide
investment  results that correspond each day to twice of the inverse  (opposite)
of the performance of the NASDAQ 100 IndexTM. It is the policy of the UltraShort
OTC ProFund to pursue its investment objective of correlating with its benchmark
regardless of market conditions, to remain nearly fully invested and not to take
defensive positions.

     The UltraShort OTC ProFund is designed to allow investors to seek to profit
from  anticipated  decreases  in the NASDAQ 100  IndexTM or to hedge an existing
portfolio of  securities  or mutual fund shares.  The  UltraShort  OTC ProFund's
investment  objective  is to  provide  investment  results  that will  inversely
correlate to 200% of the  performance of the NASDAQ 100 IndexTM.  The UltraShort
OTC ProFund seeks to achieve this inverse correlation on each trading day.

     If the  ProFund  achieved  a perfect  inverse  correlation  for any  single
trading  day,  the net asset value of the shares of the  UltraShort  OTC ProFund
would increase for that day  proportional  to twice any decrease in the level of
the NASDAQ 100  IndexTM.  Conversely,  the net asset  value of the shares of the
UltraShort  OTC ProFund would  decrease for that day  proportional  to twice any
increase in the level of the NASDAQ 100 IndexTM for that day.

     For  example,  if the  NASDAQ  100  IndexTM  were  to  decrease  by 1% on a
particular day, investors in the UltraShort OTC ProFund should experience a gain
in net asset value of approximately 2% for that day.  Conversely,  if the NASDAQ
100 IndexTM  were to  increase  by 1% by the close of  business on a  particular
trading day,  investors in the UltraShort OTC ProFund would experience a loss in
net asset value of approximately 2%.

     In pursuing its investment objective,  the UltraShort OTC ProFund generally
does not invest in  traditional  securities,  such as common  stock of operating
companies.  Rather,  the  UltraShort  OTC  ProFund  employs  certain  investment
techniques,  including  engaging in short sales and in certain  transactions  in
stock index futures  contracts,  options on stock index futures  contracts,  and
options on securities and stock indexes.

     Under these  techniques,  the UltraShort OTC ProFund will generally incur a
loss if the price of the underlying security or index increases between the date
of the  employment  of the technique  and the date on which the  UltraShort  OTC
ProFund  terminates  the position.  The  UltraShort  OTC ProFund will  generally
realize a gain if the  underlying  security or index  declines in price  between
those dates.  The amount of any gain or loss on an  investment  technique may be
affected by any  premium or amounts in lieu of  dividends  or interest  that the
UltraShort OTC ProFund pays or receives as the result of the transaction. Due to
the nature of the UltraShort OTC ProFund, investors could experience substantial
losses during  sustained  periods of rising equity prices.  This is the opposite
likely  result  expected of investing in a  traditional  equity mutual fund in a
generally rising stock market.

     Companies  whose  securities  are  traded on the  over-the-counter  ("OTC")
markets generally have smaller market capitalization or are newer companies than
those  listed on the NYSE or the  American  Stock  Exchange  (the  "AMEX").  OTC
companies  often have  limited  product  lines,  or  relatively  new products or
services, and may lack established markets, depth of experienced management,  or
financial  resources and the ability to generate funds.  The securities of these
companies may have limited  marketability and may be more volatile in price than
securities of larger capitalized or more well-known companies. Among the reasons
for the greater price  volatility of securities of certain smaller OTC companies
are the less certain growth  prospects of comparably  smaller  firms,  the lower
degree of  liquidity  in the OTC  markets for such  securities,  and the greater
sensitivity of smaller capitalization  companies to changing economic conditions
than larger capitalization, exchange-traded securities. Conversely, because many
of these OTC  securities  may be overlooked by investors and  undervalued in the
marketplace, there is potential for significant capital appreciation.

THE ULTRAEUROPE AND ULTRASHORT EUROPE PROFUNDS

     The  investment   objective  of  the  UltraEurope  ProFund  is  to  provide
investment  returns that correspond to 200% of the daily performance of the PEI.
Under its investment  objective,  the UltraEurope ProFund should produce greater
gains to investors  when the PEI rises and greater  losses when the PEI declines
over the corresponding gain or loss of the PEI itself.

     The  UltraShort  Europe  ProFund is designed to allow  investors to seek to
profit from anticipated  decreases in the PEI or to hedge an existing  portfolio
of securities or mutual fund shares. The UltraShort Europe ProFund's  investment
objective is to provide investment results that will inversely correlate to 200%
of the  performance of the PEI. The  UltraShort  Europe ProFund seeks to achieve
this inverse correlation on each business day.

     If the UltraShort Europe ProFund achieved a perfect inverse correlation for
any single  trading day, the net asset value of the shares of the ProFund  would
increase  for that day  proportional  to twice any  decrease in the level of the
PEI.  Conversely,  the net asset  value of the shares of the  UltraShort  Europe
ProFund would  decrease for that day  proportional  to twice any increase in the
level of the PEI for that day.

     For  example,  if the  PEI  were to  decrease  by 1% on a  particular  day,
investors in the UltraShort Europe ProFund should experience a gain in net asset
value of approximately 2% for that day. Conversely,  if the PEI were to increase
by 1% by the close of business on a  particular  trading  day,  investors in the
UltraShort  Europe  ProFund  would  experience  a loss  in net  asset  value  of
approximately 2%.

     In pursuing  their  investment  objectives,  the ProFunds  generally do not
invest in traditional  securities,  such as common stock of operating companies.
Rather, the ProFunds employ certain investment techniques, including engaging in
short sales and in certain transactions in stock index future contracts, options
on stock index future contracts, and options on securities and stock indexes.

     Investing in foreign  companies or financial  instruments by these ProFunds
(directly  or  indirectly)  may  involve  risks not  typically  associated  with
investing in U.S.  companies.  The value of  securities  denominated  in foreign
currencies, and of dividends from such securities, can change significantly when
foreign  currencies  strengthen or weaken relative to the U.S.  Dollar.  Foreign
securities  markets  generally  have less trading volume and less liquidity than
U.S. markets, and prices in some foreign markets can be extremely volatile. Many
foreign  countries lack uniform  accounting and  disclosure  standards.  Because
these ProFunds will invest  indirectly in foreign markets,  they will be subject
to the market, economic and political risks prevalent in these foreign markets.

     Changes in foreign  exchange  rates will affect the value of  securities of
financial  instruments  denominated or quoted in currencies  other than the U.S.
Dollar, and the ProFunds will not engage in activities designed to hedge against
foreign currency exchange rate fluctuations. Foreign currency exchange rates may
fluctuate   significantly  over  short  periods  of  time.  They  generally  are
determined  by forces of supply and demand in the foreign  exchange  markets and
the relative merits of investments in different  countries,  actual or perceived
changes  in  interest  rates  and  other  complex  factors,   as  seen  from  an
international  perspective.   Currency  exchange  rates  also  can  be  affected
unpredictably  by  intervention  (or  failure to  intervene)  by U.S. or foreign
governments or central banks, by currency controls or by political  developments
in the U.S. or abroad.
<PAGE>


     On January 1, 1999, the European  Monetary Union (EMU) began to implement a
new currency unit,  the Euro,  which is expected to reshape  financial  markets,
banking systems and monetary  policies,  in Europe and other parts of the world.
Although it is not  possible  to predict  the impact of the Euro  implementation
plan on the  ProFunds,  the  transition  to the Euro  may  change  the  economic
environment and behavior of investors, particularly in European markets.

THE MONEY MARKET PROFUND

     The Money Market  ProFund seeks a high level of current  income  consistent
with  liquidity  and the  preservation  of capital  through  investment  in high
quality money market  instruments.  The Money Market ProFund offers  investors a
convenient means of diversifying  their holdings of short-term  securities while
relieving those investors of the  administrative  burdens  typically  associated
with purchasing and holding these instruments,  such as coordinating  maturities
and reinvestments,  providing for safekeeping and maintaining  detailed records.
High  quality,   short-term  instruments  may  result  in  a  lower  yield  than
instruments with a lower quality and/or a longer term.

     The Money  Market  ProFund  seeks to achieve its  investment  objective  by
investing its assets in the Portfolio,  which has the same investment  objective
as the Money  Market  ProFund and is managed by Bankers  Trust,  130 Liberty St.
(One Bankers Trust Plaza),  New York, New York 10006.  There can be no assurance
that the  investment  objective  of  either  the  Money  Market  ProFund  or the
Portfolio  will be  achieved.  The  investment  objectives  of the Money  Market
ProFund  and the  Portfolio  are  fundamental  policies  and may not be  changed
without  the  approval  of  the  Money  Market  ProFund's  shareholders  or  the
Portfolio's  investors,   respectively.   See  "Special  Information  Concerning
MasterFeeder Fund Structure" herein.

     The Portfolio invests in money market instruments, including corporate debt
obligations,   U.S.  government  securities,  bank  obligations  and  repurchase
agreements.   See  "Investment   Policies  and  Techniques  --  Cash  Management
Portfolio"  for  a  discussion  of  the  Portfolio's  investment  policies.  The
Portfolio  follows  practices  which are  designed  to enable  the Money  Market
ProFund to  maintain  a $1.00  share  price:  limiting  dollar-weighted  average
maturity of the  securities  held by the  Portfolio  to 90 days or less;  buying
securities which have remaining  maturities of 397 days or less; and buying only
high quality  securities with minimal credit risks. Of course,  the Money Market
ProFund  cannot  guarantee  a $1.00 share  price,  but these  practices  help to
minimize  any price  fluctuations  that might  result from  rising or  declining
interest  rates.  While the  Portfolio  invests  in high  quality  money  market
securities,  you should be aware that your  investment is not without risk.  All
money market  instruments can change in value when interest rates or an issuer's
creditworthiness changes.

FUTURES CONTRACTS AND RELATED OPTIONS

     The  ProFunds  (other than the Money  Market  ProFund) may purchase or sell
stock  index  futures  contracts  and  options  thereon  as a  substitute  for a
comparable market position in the underlying securities or to satisfy regulation
requirements.  A futures  contract  obligates  the  seller to  deliver  (and the
purchaser to take delivery of) the specified commodity on the expiration date of
the  contract.  A stock index futures  contract  obligates the seller to deliver
(and the purchaser to take) an amount of cash equal to a specific  dollar amount
multiplied by the difference  between the value of a specific stock 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 stocks in the index is
made.

     When a ProFund  purchases a put or call option on a futures  contract,  the
ProFund pays a premium for the right to sell or purchase the underlying  futures
contract  for a  specified  price upon  exercise  at any time  during the option
period.  By writing  (selling)  a put or call  option on a futures  contract,  a
ProFund receives a premium in return for granting to the purchaser of the option
the right to sell to or buy from the ProFund the underlying futures contract for
a specified price upon exercise at any time during the option period.
<PAGE>

     Whether a ProFund realizes a gain or loss from futures  activities  depends
generally  upon  movements  in  the  underlying  commodity.  The  extent  of the
ProFund's  loss from an unhedged  short  position in futures  contracts  or from
writing options on futures contracts is potentially unlimited.  The ProFunds may
engage in  related  closing  transactions  with  respect  to  options on futures
contracts.  The ProFunds will engage in  transactions  in futures  contracts and
related  options  that are traded on a U.S.  exchange  or board of trade or that
have  been  approved  for  sale in the U.S.  by the  Commodity  Futures  Trading
Commission.

     When a ProFund purchases or sells a stock index futures contract,  or sells
an option thereon,  the ProFund "covers" its position.  To cover its position, a
ProFund may enter into an  offsetting  position or maintain  with its  custodian
bank (and  mark-to-market on a daily basis) a segregated  account  consisting of
liquid  instruments  that,  when added to any amounts  deposited  with a futures
commission  merchant  as margin,  are equal to the market  value of the  futures
contract or otherwise "cover" its position.

     The non-money  market ProFunds may purchase and sell futures  contracts and
options thereon only to the extent that such activities would be consistent with
the requirements of Section 4.5 of the regulations under the Commodity  Exchange
Act  promulgated  by  the  Commodity  Futures  Trading   Commission  (the  "CFTC
Regulations"),  under which each of these  ProFunds  would be excluded  from the
definition  of a  "commodity  pool  operator."  Under  Section  4.5 of the  CFTC
Regulations, a ProFund may engage in futures transactions, either for "bona fide
hedging"  purposes,  as this term is  defined  in the CFTC  Regulations,  or for
non-hedging purposes to the extent that the aggregate initial margins and option
premiums  required to establish such  non-hedging  positions do not exceed 5% of
the liquidation  value of the ProFund's  portfolio.  In the case of an option on
futures  contracts that is  "in-the-money"  at the time of purchase  (i.e.,  the
amount by which the exercise  price of the put option exceeds the current market
value of the underlying security or the amount by which the current market value
of the underlying  security exceeds the exercise price of the call option),  the
in-the-money amount may be excluded in calculating this 5% limitation.

     The ProFunds will cover their positions when they write a futures  contract
or option on a futures  contract.  A ProFund may "cover" its long  position in a
futures  contract by purchasing a put option on the same futures contract with a
strike price (i.e.,  an exercise  price) as high or higher than the price of the
futures  contract,  or, if the strike price of the put is less than the price of
the futures contract,  the ProFund will maintain in a segregated account cash or
liquid  instruments equal in value to the difference between the strike price of
the put and the price of the future.  A ProFund may also cover its long position
in a futures  contract by taking a short position in the instruments  underlying
the futures contract,  or by taking positions in instruments the prices of which
are  expected  to move  relatively  consistently  with the futures  contract.  A
ProFund  may cover its short  position  in a futures  contract  by taking a long
position  in the  instruments  underlying  the  futures  contract,  or by taking
positions in  instruments  the prices of which are  expected to move  relatively
consistently with the futures contract.

     A  ProFund  may cover its sale of a call  option on a futures  contract  by
taking a long position in the underlying  futures  contract at a price less than
or equal to the strike price of the call option, or, if the long position in the
underlying  futures  contract is  established at a price greater than the strike
price of the written  (sold)  call,  the ProFund  will  maintain in a segregated
account liquid  instruments equal in value to the difference  between the strike
price of the call and the price of the future. A ProFund may also cover its sale
of a call  option by taking  positions  in  instruments  the prices of which are
expected to move  relatively  consistently  with the call option.  A ProFund may
cover its sale of a put option on a futures  contract by taking a short position
in the  underlying  futures  contract  at a price  greater  than or equal to the
strike  price of the put option,  or, if the short  position  in the  underlying
futures  contract is  established  at a price less than the strike  price of the
written  put,  the  ProFund  will  maintain  in a  segregated  account  cash  or
high-grade  liquid debt securities equal in value to the difference  between the
strike  price of the put and the price of the  future.  A ProFund may also cover
its sale of a put option by taking  positions in instruments the prices of which
are expected to move relatively consistently with the put option.

     Although the ProFunds intend to sell futures  contracts only if there is an
active market for such contracts, no assurance can be given that a liquid market
will exist for any  particular  contract at any  particular  time.  Many futures
exchanges  and boards of trade  limit the  amount of  fluctuation  permitted  in
futures  contract  prices during a single  trading day. Once the daily limit has
been reached in a particular contract, no trades may be made that day at a price
beyond that limit or trading may be suspended for specified  periods  during the
day.  Futures  contract  prices could move to the limit for several  consecutive
trading days with little or no trading, thereby preventing prompt liquidation of
futures positions and potentially subjecting a ProFund to substantial losses. If
trading  is not  possible,  or if a  ProFund  determines  not to close a futures
position  in  anticipation  of adverse  price  movements,  the  ProFund  will be
required to make daily cash  payments  of  variation  margin.  The risk that the
ProFund  will be unable to close out a futures  position  will be  minimized  by
entering into such transactions on a national exchange with an active and liquid
secondary market.

INDEX OPTIONS

     The ProFunds  (other than the Money Market  ProFund) may purchase and write
options on stock indexes to create  investment  exposure  consistent  with their
investment  objectives,  hedge or limit the exposure of their  positions  and to
create synthetic money market positions. See "Taxation" herein.

     A stock index  fluctuates  with changes in the market  values of the stocks
included  in the index.  Options on stock  indexes  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 stock index upon which the
option is based being  greater than (in the case of a call) or less than (in the
case of a put) the exercise price of the option. The amount of cash received, if
any,  will be the  difference  between  the  closing  price of the index and the
exercise price of the option,  multiplied by a specified  dollar  multiple.  The
writer (seller) of the option is obligated,  in return for the premiums received
from the  purchaser  of the  option,  to make  delivery  of this  amount  to the
purchaser. All settlements of index options transactions are in cash.

     Index  options  are subject to  substantial  risks,  including  the risk of
imperfect  correlation  between the option price and the value of the underlying
securities  composing the stock index selected and the risk that there might not
be a liquid  secondary  market  for the  option.  Because  the value of an index
option depends upon movements in the level of the index rather than the price of
a  particular  stock,  whether  a ProFund  will  realize a gain or loss from the
purchase or writing  (sale) of options on an index depends upon movements in the
level of stock prices in the stock market  generally  or, in the case of certain
indexes,  in an industry or market  segment,  rather than upon  movements in the
price of a particular stock.  Whether a ProFund will realize a profit or loss by
the use of options on stock indexes will depend on movements in the direction of
the stock market generally or of a particular  industry or market segment.  This
requires  different  skills and  techniques  than are  required  for  predicting
changes  in the price of  individual  stocks.  A ProFund  will not enter into an
option  position  that exposes the ProFund to an  obligation  to another  party,
unless the ProFund either (i) owns an offsetting position in securities or other
options  and/or  (ii)  maintains  with  the  ProFund's   custodian  bank  liquid
instruments  that,  when added to the  premiums  deposited  with  respect to the
option,  are  equal  to the  market  value of the  underlying  stock  index  not
otherwise covered.

     The non-money  market  ProFunds may engage in  transactions  in stock index
options   listed   on   national   securities   exchanges   or   traded  in  the
over-the-counter  market as an  investment  vehicle for the purpose of realizing
the ProFund's investment objective.  Options on indexes are settled in cash, not
by delivery of securities.  The exercising  holder of an index option  receives,
instead of a security, cash equal to the difference between the closing price of
the securities index and 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.
Options currently are traded on the Chicago Board Options Exchange (the "CBOE"),
the AMEX, and other exchanges ("Exchanges").  Purchased over-the-counter options
and the  cover for  written  over-the-counter  options  will be  subject  to the
respective  ProFund's 15% limitation on investment in illiquid  securities.  See
"Illiquid Securities."

     Each of the Exchanges  has  established  limitations  governing the maximum
number of call or put  options on the same index  which may be bought or written
(sold) by a single  investor,  whether  acting  alone or in concert  with others
(regardless  of  whether  such  options  are  written  on the same or  different
Exchanges or are held or written on one or more  accounts or through one or more
brokers). Under these limitations,  option positions of all investment companies
advised by the same  investment  adviser  are  combined  for  purposes  of these
limits. Pursuant to these limitations,  an Exchange may order the liquidation of
positions and may impose other sanctions or restrictions.  These position limits
may  restrict  the  number of listed  options  which a ProFund  may buy or sell;
however, the Advisor intends to comply with all limitations.

OPTIONS ON SECURITIES


     The  non-money  market  ProFunds  may  buy  and  write  (sell)  options  on
securities for the purpose of realizing their  respective  ProFund's  investment
objective.  By buying a call  option,  a ProFund has the right,  in return for a
premium paid during the term of the option, to buy the securities underlying the
option at the exercise price. By writing a call option on securities,  a ProFund
becomes  obligated  during  the  term  of the  option  to  sell  the  securities
underlying  the  option at the  exercise  price if the option is  exercised.  By
buying a put  option,  a ProFund  has the right,  in return  for a premium  paid
during the term of the option,  to sell the securities  underlying the option at
the exercise price. By writing a put option, a ProFund becomes  obligated during
the term of the option to purchase the  securities  underlying the option at the
exercise  price if the option is exercised.  During the term of the option,  the
writer may be assigned an exercise notice by the broker-dealer  through whom the
option was sold. The exercise notice would require the writer to deliver, in the
case of a call,  or take  delivery  of,  in the  case of a put,  the  underlying
security against payment of the exercise price. This obligation  terminates upon
expiration  of the option,  or at such  earlier  time that the writer  effects a
closing  purchase   transaction  by  purchasing  an  option  covering  the  same
underlying  security and having the same exercise price and  expiration  date as
the one previously  sold. Once an option has been exercised,  the writer may not
execute a closing purchase transaction.  To secure the obligation to deliver the
underlying security in the case of a call option, the writer of a call option is
required  to  deposit  in escrow  the  underlying  security  or other  assets in
accordance with the rules of the Options Clearing  Corporation  (the "OCC"),  an
institution  created to interpose  itself between buyers and sellers of options.
The OCC  assumes the other side of every  purchase  and sale  transaction  on an
exchange and, by doing so, gives its guarantee to the transaction.  When writing
call  options on  securities,  a ProFund  may cover its  position  by owning the
underlying security on which the option is written.  Alternatively,  the ProFund
may cover its position by owning a call option on the underlying security,  on a
share for share basis, which is deliverable under the option contract at a price
no higher than the exercise  price of the call option written by the ProFund or,
if higher,  by owning  such call  option and  depositing  and  maintaining  in a
segregated  account cash or liquid  instruments equal in value to the difference
between the two exercise prices.  In addition,  a ProFund may cover its position
by depositing and maintaining in a segregated account cash or liquid instruments
equal in value to the exercise  price of the call option written by the ProFund.
When a ProFund  writes a put  option,  the  ProFund  will have and  maintain  on
deposit with its custodian bank cash or liquid  instruments having a value equal
to the exercise value of the option. The principal reason for a ProFund to write
call options on stocks held by the ProFund is to attempt to realize, through the
receipt of premiums,  a greater  return than would be realized on the underlying
securities alone.

     If a ProFund  that  writes an option  wishes  to  terminate  the  ProFund's
obligation, the ProFund may effect a "closing purchase transaction." The ProFund
accomplishes  this  by  buying  an  option  of the  same  series  as the  option
previously  written  by the  ProFund.  The  effect of the  purchase  is that the
writer's position will be canceled by the OCC. However,  a writer may not effect
a  closing  purchase  transaction  after the  writer  has been  notified  of the
exercise of an option.  Likewise, a ProFund which is the holder of an option may
liquidate  its position by effecting a "closing sale  transaction."  The ProFund
accomplishes  this by  selling  an  option  of the  same  series  as the  option
previously purchased by the ProFund. There is no guarantee that either a closing
purchase  or a closing  sale  transaction  can be  effected.  If any call or put
option is not  exercised  or sold,  the  option  will  become  worthless  on its
expiration date. A ProFund will realize a gain (or a loss) on a closing purchase
transaction  with  respect to a call or a put option  previously  written by the
ProFund if the premium,  plus commission  costs, paid by the ProFund to purchase
the call or put option to close the  transaction  is less (or greater)  than the
premium,  less commission costs, received by the ProFund on the sale of the call
or the put option.  The ProFund also will realize a gain if a call or put option
which the ProFund  has written  lapses  unexercised,  because the ProFund  would
retain the premium.

     Although  certain  securities  exchanges  attempt to  provide  continuously
liquid  markets in which  holders  and  writers  of options  can close out their
positions at any time prior to the expiration of the option, no assurance can be
given  that a  market  will  exist  at all  times  for all  outstanding  options
purchased or sold by a ProFund. If an options market were to become unavailable,
the ProFund would be unable to realize its profits or limit its losses until the
ProFund could exercise  options it holds, and the ProFund would remain obligated
until options it wrote were exercised or expired.
<PAGE>

SHORT SALES

     The Bear ProFund, the UltraBear ProFund, the UltraShort OTC ProFund and the
UltraShort Europe ProFund may engage in short sales transactions under which the
ProFund  sells a security it does not own. To complete such a  transaction,  the
ProFund must borrow the security to make delivery to the buyer. The ProFund then
is obligated to replace the security  borrowed by purchasing the security at the
market price at the time of  replacement.  The price at such time may be more or
less than the price at which the  security  was sold by the  ProFund.  Until the
security is replaced, the ProFund is required to pay to the lender amounts equal
to any  dividends  or interest  which accrue  during the period of the loan.  To
borrow the  security,  the ProFund also may be required to pay a premium,  which
would  increase  the cost of the security  sold.  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 the  ProFund  closes its short  position  or  replaces  the  borrowed
security,  the ProFund will cover its position  with an  offsetting  position or
maintain a segregated  account  containing cash or liquid  instruments at such a
level that the amount  deposited in the account plus the amount  deposited  with
the broker as  collateral  will equal the  current  value of the  security  sold
short.

SWAP AGREEMENTS

     The ProFunds  (other than the Money  Market  ProFund) may enter into equity
index or  interest  rate swap  agreements  for  purposes of  attempting  to gain
exposure  to the stocks  making up an index of  securities  in a market  without
actually  purchasing those stocks,  or to hedge a position.  Swap agreements are
two-party  contracts  entered into  primarily  by  institutional  investors  for
periods  ranging  from a day  to  more  than  one  year.  In a  standard  "swap"
transaction,  two parties  agree to exchange  the returns (or  differentials  in
rates of return) earned or realized on particular  predetermined  investments or
instruments.  The gross returns to be exchanged or "swapped" between the parties
are  calculated  with  respect to a "notional  amount,"  i.e.,  the return on or
increase  in value of a  particular  dollar  amount  invested  in a "basket"  of
securities  representing a particular  index.  Forms of swap agreements  include
interest rate caps,  under which,  in return for a premium,  one party agrees to
make payments to the other to the extent that interest  rates exceed a specified
rate, or "cap";  interest rate floors, under which, in return for a premium, one
party  agrees to make  payments to the other to the extent that  interest  rates
fall below a specified level, or "floor"; and interest rate collars, under which
a party sells a cap and purchases a floor or vice versa in an attempt to protect
itself  against  interest  rate  movements  exceeding  given  minimum or maximum
levels.

     Most swap agreements entered into by the ProFunds calculate the obligations
of the parties to the  agreement  on a "net  basis."  Consequently,  a ProFund's
current  obligations  (or rights) under a swap agreement will generally be equal
only to the net amount to be paid or received  under the agreement  based on the
relative  values of the positions  held by each party to the agreement (the "net
amount").

     A ProFund's  current  obligations  under a swap  agreement  will be accrued
daily  (offset  against any amounts  owing to the  ProFund)  and any accrued but
unpaid net amounts owed to a swap  counterparty  will be covered by  segregating
assets  determined to be liquid.  Obligations  under swap  agreements so covered
will not be  construed  to be "senior  securities"  for  purposes of a ProFund's
investment restriction concerning senior securities.  Because they are two party
contracts  and  because  they may have terms of greater  than seven  days,  swap
agreements  may  be  considered  to  be  illiquid  for  the  ProFunds'  illiquid
investment  limitations.  A  Portfolio  will not enter  into any swap  agreement
unless  the  Advisor  believes  that  the  other  party  to the  transaction  is
creditworthy.  A ProFund  bears the risk of loss of the  amount  expected  to be
received  under a swap  agreement in the event of the default or bankruptcy of a
swap agreement counterparty.

     Each non-money market ProFund may enter into swap agreements to invest in a
market without owning or taking physical  custody of securities in circumstances
in which  direct  investment  is  restricted  for legal  reasons or is otherwise
impracticable.  The counterparty to any swap agreement will typically be a bank,
investment banking firm or broker/dealer.  The counterparty will generally agree
to pay the ProFund the amount,  if any, by which the notional amount of the swap
agreement  would have  increased in value had it been invested in the particular
stocks,  plus the dividends  that would have been received on those stocks.  The
ProFund will agree to pay to the counterparty a floating rate of interest on the
notional  amount of the swap  agreement  plus the  amount,  if any, by which the
notional  amount  would have  decreased  in value had it been  invested  in such
stocks. Therefore, the return to the ProFund on any swap agreement should be the
gain or loss on the  notional  amount  plus  dividends  on the  stocks  less the
interest paid by the ProFund on the notional amount.
<PAGE>

     Swap agreements  typically are settled on a net basis, which means that the
two payment streams are netted out, with the ProFund receiving or paying, as the
case may be, only the net amount of the two  payments.  Payments  may be made at
the  conclusion  of a swap  agreement  or  periodically  during  its term.  Swap
agreements do not involve the delivery of securities or other underlying assets.
Accordingly,  the risk of loss with respect to swap agreements is limited to the
net amount of payments that a ProFund is contractually obligated to make. If the
other party to a swap agreement  defaults,  a ProFund's risk of loss consists of
the net amount of payments that such Fund is contractually  entitled to receive,
if any. The net amount of the excess,  if any, of a ProFund's  obligations  over
its  entitlements  with  respect to each  equity swap will be accrued on a daily
basis  and an amount of cash or liquid  assets,  having an  aggregate  net asset
value at least equal to such accrued  excess will be  maintained in a segregated
account by a ProFund's  custodian.  Inasmuch as these  transactions  are entered
into for hedging purposes or are offset by segregated cash of liquid assets,  as
permitted  by  applicable  law,  the  ProFunds  and their  Advisor  believe that
transactions do not constitute  senior  securities under the Investment  Company
Act of 1940, as amended (the "1940 Act") and,  accordingly,  will not treat them
as being subject to a ProFund's borrowing restrictions.

     The swap market has grown substantially in recent years with a large number
of banks and  investment  banking firms acting both as principals  and as agents
utilizing  standardized  swap  documentation.  As a result,  the swap market has
become  relatively  liquid in  comparison  with the  markets  for other  similar
instruments which are traded in the over-the-counter  market. The Advisor, under
the  supervision of the Board of Trustees,  are  responsible for determining and
monitoring the liquidity of the ProFunds' transactions in swap agreements.

     The use of equity swaps is a highly  specialized  activity  which  involves
investment  techniques and risks  different from those  associated with ordinary
portfolio securities  transactions.  Reasons for the absence of liquid secondary
market on an  exchange  include  the  following:  (i) there may be  insufficient
trading  interest in certain  options;  (ii)  restrictions  may be imposed by an
exchange  on opening or  closing  transactions  or both;  (iii)  trading  halts,
suspensions  or other  restrictions  may be imposed with  respect to  particular
classes or series of  options;  (iv)  unusual or  unforeseen  circumstances  may
interrupt normal operations on an exchange; (v) the facilities of an exchange or
the OCC may not at all times be adequate to handle current  trading  volume;  or
(vi) one or more exchanges  could,  for economic or other reasons,  decide or be
compelled  at some  future  date to  discontinue  the  trading of options  (or a
particular  class  or  series  of  options)  would  cease  to  exist,   although
outstanding options on that exchange that had been issued by the OCC as a result
of trades on that exchange would  continue to be exercisable in accordance  with
their terms.

U.S. GOVERNMENT SECURITIES

     Each  non-money  market  ProFund and the Portfolio  also may invest in U.S.
government securities in pursuit of their investment objectives,  as "cover" for
the investment techniques these ProFunds employ, or for liquidity purposes.

     Yields on 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 yields and are generally  subject to
potentially greater 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 market interest rates. An
increase in interest rates,  therefore,  would generally reduce the market value
of a ProFund's  portfolio  investments in U.S.  government  securities,  while a
decline in  interest  rates  would  generally  increase  the  market  value of a
ProFund's portfolio investments in these securities.
<PAGE>

     U.S.  government  securities  include U.S. Treasury  securities,  which are
backed by the full faith and credit of the U.S.  Treasury  and which differ only
in their interest rates, maturities,  and times of issuance. U.S. Treasury bills
have initial  maturities of one year or less;  U.S.  Treasury notes have initial
maturities of one to ten years;  and U.S.  Treasury bonds generally have initial
maturities of greater than ten years.  Certain U.S.  government  securities  are
issued or guaranteed  by agencies or  instrumentalities  of the U.S.  government
including,  but not  limited  to,  obligations  of U.S.  government  agencies or
instrumentalities,  such  as the  Federal  National  Mortgage  Association,  the
Government National Mortgage Association, the Small Business Administration, the
Federal  Farm  Credit  Administration,  the Federal  Home Loan Banks,  Banks for
Cooperatives  (including  the Central  Bank for  Cooperatives),the  Federal Land
Banks, the Federal  Intermediate  Credit Banks, the Tennessee Valley  Authority,
the Export-Import Bank of the United States,  the Commodity Credit  Corporation,
the Federal  Financing  Bank,  the Student Loan Marketing  Association,  and the
National Credit Union  Administration.  Some obligations issued or guaranteed by
U.S.  government  agencies  and  instrumentalities,   including,   for  example,
Government  National  Mortgage  Association   pass-through   certificates,   are
supported by the full faith and credit of the U.S.  Treasury.  Other obligations
issued by or guaranteed by Federal agencies,  such as those securities issued by
the Federal National  Mortgage  Association,  are supported by the discretionary
authority of the U.S.  government to purchase certain obligations of the federal
agency,  while other  obligations  issued by or guaranteed by federal  agencies,
such as those of the Federal Home Loan Banks,  are supported by the right of the
issuer to borrow  from the U.S.  Treasury.  While the U.S.  government  provides
financial  support  to  such  U.S.  government-sponsored  Federal  agencies,  no
assurance  can be given that the U.S.  government  will always do so,  since the
U.S.  Government  is not so  obligated  by law.  U.S.  Treasury  notes and bonds
typically pay coupon interest semi-annually and repay the principal at maturity.

REPURCHASE AGREEMENTS

         Each  of  the  ProFunds  may  enter  into  repurchase  agreements  with
financial institutions. Under a repurchase agreement, a ProFund purchases a debt
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 purchaser's  holding period.  While
the maturities of the underlying  securities in repurchase  transactions  may be
more than one year,  the term of each  repurchase  agreement will always be less
than one year. The ProFunds follow certain  procedures  designed to minimize the
risks inherent in such agreements. These procedures include effecting repurchase
transactions only with large,  well-capitalized and  well-established  financial
institutions  whose condition will be continually  monitored by the Advisor and,
in the case of the Money Market ProFund,  Bankers Trust. In addition,  the value
of the collateral  underlying  the repurchase  agreement will always be at least
equal to the  repurchase  price,  including any accrued  interest  earned on the
repurchase  agreement.  In the event of a  default  or  bankruptcy  by a selling
financial  institution,  a ProFund will seek to liquidate such collateral  which
could involve  certain costs or delays and, to the extent that proceeds from any
sale  upon a  default  of the  obligation  to  repurchase  were  less  than  the
repurchase price, the ProFund could suffer a loss. A ProFund also may experience
difficulties  and incur certain costs in exercising its rights to the collateral
and may lose the interest the ProFund  expected to receive under the  repurchase
agreement. Repurchase agreements usually are for short periods, such as one week
or less,  but may be longer.  It is the current  policy of the  ProFunds  not to
invest in repurchase agreements that do not mature within seven days if any such
investment,  together with any other liquid assets held by the ProFund,  amounts
to more than 15% (10% with respect to the Money Market ProFund) of the ProFund's
total  net  assets.  The  investments  of each  of the  ProFunds  in  repurchase
agreements at times may be substantial  when, in the view of the Advisor and, in
the case of the Money Market  ProFund,  Bankers  Trust,  liquidity,  investment,
regulatory, or other considerations so warrant.

CASH RESERVES

     To seek its investment objective as a cash reserve, for liquidity purposes,
or as "cover" for positions it has taken,  each ProFund may  temporarily  invest
all or part of the ProFund's assets in cash or cash equivalents,  which include,
but are not limited to,  short-term money market  instruments,  U.S.  government
securities,   certificates  of  deposit,  bankers  acceptances,   or  repurchase
agreements secured by U.S. government securities.
<PAGE>

REVERSE REPURCHASE AGREEMENTS

     The non-money market ProFunds and the Portfolio may use reverse  repurchase
agreements as part of that ProFund's  investment  strategy.  Reverse  repurchase
agreements involve sales by a ProFund/Portfolio of portfolio assets concurrently
with an agreement by the  ProFund/Portfolio  to repurchase  the same assets at a
later date at a fixed price. Generally, the effect of such a transaction is that
the  ProFund/Portfolio  can  recover  all or most of the  cash  invested  in the
portfolio  securities  involved  during  the  term  of  the  reverse  repurchase
agreement,  while the ProFund/Portfolio will be able to keep the interest income
associated with those portfolio  securities.  Such transactions are advantageous
only if the interest  cost to the  ProFund/Portfolio  of the reverse  repurchase
transaction is less than the cost of obtaining the cash otherwise. Opportunities
to   achieve   this   advantage   may  not   always   be   available,   and  the
ProFund/Portfolios  intend to use the reverse repurchase  technique only when it
will  be to the  ProFund/Portfolio's  advantage  to do so and the  Money  Market
ProFund will not invest more than 5% of its total  assets in reverse  repurchase
agreements.  The  ProFund/Portfolios  will  establish a segregated  account with
their custodian bank in which the ProFund/Portfolio will maintain cash or liquid
instruments equal in value to the ProFund/Portfolio's  obligations in respect of
reverse repurchase agreements.

BORROWING

     The ProFunds  (other than the Portfolio  except to the degree the Portfolio
may  borrow for  temporary  or  emergency  purposes)  may borrow  money for cash
management  purposes  or  investment  purposes.  Each  of the  non-money  market
ProFunds may also enter into reverse repurchase agreements,  which may be viewed
as a form of borrowing,  with financial  institutions.  However, to the extent a
ProFund  "covers" its  repurchase  obligations  as  described  above in "Reverse
Repurchase  Agreements,"  such  agreement will not be considered to be a "senior
security"  and,  therefore,  will  not be  subject  to the 300%  asset  coverage
requirement  otherwise  applicable to borrowings by the ProFunds.  Borrowing for
investment  is  known  as  leveraging.  Leveraging  investments,  by  purchasing
securities  with borrowed  money,  is a speculative  technique  which  increases
investment risk, but also increases investment opportunity.  Since substantially
all of a  ProFund's  assets  will  fluctuate  in  value,  whereas  the  interest
obligations  on  borrowings  may be fixed,  the net asset value per share of the
ProFund will increase more when the ProFund's portfolio assets increase in value
and decrease more when the  ProFund's  portfolio  assets  decrease in value than
would  otherwise  be the  case.  Moreover,  interest  costs  on  borrowings  may
fluctuate  with changing  market rates of interest and may  partially  offset or
exceed the returns on the borrowed funds.  Under adverse  conditions,  a ProFund
might have to sell portfolio  securities to meet interest or principal  payments
at a time when investment considerations would not favor such sales.

     As required by the  Investment  Company Act of 1940,  as amended (the "1940
Act"),  a  ProFund  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
ProFund's  assets  should fail to meet this 300%  coverage  test,  the  ProFund,
within three days (not including  Sundays and holidays),  will reduce the amount
of the ProFund's  borrowings to the extent necessary to meet this 300% coverage.
Maintenance  of this  percentage  limitation may result in the sale of portfolio
securities at a time when investment  considerations  otherwise indicate that it
would be  disadvantageous  to do so. In addition to the foregoing,  the ProFunds
are  authorized  to  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 the ProFund's  total assets.  This  borrowing is not subject to the foregoing
300% asset coverage requirement. The ProFunds are authorized to pledge portfolio
securities as the Advisor deems appropriate in connection with any borrowings.

LENDING OF PORTFOLIO SECURITIES

     Subject  to the  investment  restrictions  set  forth  below,  each  of the
ProFunds  and the  Portfolio  may  lend its  portfolio  securities  to  brokers,
dealers, and financial  institutions,  provided that cash equal to at least 100%
of the market value of the  securities  loaned is deposited by the borrower with
the  ProFund/Portfolio  and is  maintained  each  business  day in a  segregated
account pursuant to applicable  regulations.  While such securities are on loan,
the borrower will pay the lending ProFund/Portfolio any income accruing thereon,
and  the   ProFund/Portfolio   may  invest  the  cash  collateral  in  portfolio
securities, thereby earning additional income. A ProFund/Portfolio will not lend
more than 33 1/3 of the value of the  ProFund's  total  assets,  except that the
Portfolio  will not lend more than 20% of the value of its total  assets.  Loans
would  be  subject  to  termination  by the  lending  ProFund/Portfolio  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 which occurs during the term of the loan
inures  to  the  lending   ProFund/Portfolio   and  that   ProFund's/Portfolio's
shareholders.  There may be risks of delay in receiving additional collateral or
risks of delay in  recovery  of the  securities  or even  loss of  rights in the
securities  lent  should the  borrower of the  securities  fail  financially.  A
lending ProFund/Portfolio may pay reasonable finders, borrowers, administrative,
and custodial Trustees in connection with a loan. With respect to the Portfolio,
cash  collateral may be invested in a money market fund managed by Bankers Trust
(or its affiliate) and Bankers Trust may serve as the Portfolio's  lending agent
and may share in  revenue  received  from  securities  lending  transactions  as
compensation for this service.

WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES

     Each  non-money  market  ProFund  (and  to  the  extent  allowable  by  its
investment  policies,  the Money  Market  ProFund),  from  time to time,  in the
ordinary  course of  business,  may  purchase  securities  on a  when-issued  or
delayed-delivery  basis  (i.e.,  delivery  and payment can take place  between a
month and 120 days  after the date of the  transaction).  These  securities  are
subject to market  fluctuation and no interest  accrues to the purchaser  during
this period.  At the time a ProFund makes the commitment to purchase  securities
on a  when-issued  or  delayed-delivery  basis,  the  ProFund  will  record  the
transaction  and thereafter  reflect the value of the  securities,  each day, in
determining  the ProFund's net asset value.  Each non-money  market ProFund will
not purchase  securities on a  when-issued  or  delayed-delivery  basis if, as a
result,  more than 15% of the ProFund's net assets would be so invested.  At the
time of delivery of the  securities,  the value of the securities may be more or
less than the purchase price.

     The Portfolio will enter into when-issued or delayed-delivery  transactions
for the purpose of  acquiring  securities  and not for the purpose of  leverage.
When  issued  securities  purchased  by the  Portfolio  may  include  securities
purchased  on a "when,  as and if issued"  basis under which the issuance of the
securities  depends on the occurrence of a subsequent  event.  Upon purchasing a
security  on  a  when-issued  or  delayed-delivery  basis,  the  Portfolio  will
identify,  as part of a  segregated  account,  cash or liquid  securities  in an
amount at least equal to the when-issued or delayed-delivery commitment.

     The  Trust  will also  establish  a  segregated  account  with the  Trust's
custodian bank in which the ProFunds will maintain liquid  instruments  equal to
or greater in value than the ProFund's purchase commitments for such when-issued
or delayed-delivery  securities,  or the Trust does not believe that a ProFund's
net asset value or income will be adversely  affected by the ProFund's  purchase
of securities on a when-issued or delayed delivery basis.
<PAGE>

INVESTMENTS IN OTHER INVESTMENT COMPANIES

     The  ProFunds  and the  Portfolio  may  invest in the  securities  of other
investment  companies to the extent that such an investment  would be consistent
with the requirements of the 1940 Act. If a ProFund / Portfolio invests in, and,
thus, is a shareholder of, another investment company, the ProFund / Portfolio's
shareholders will indirectly bear the ProFund / Portfolio's  proportionate share
of the  fees and  expenses  paid by such  other  investment  company,  including
advisory fees, in addition to both the management  fees payable  directly by the
ProFund to the ProFund's own investment  adviser and the other expenses that the
ProFund / Portfolio  bears directly in connection with the ProFund's / Portfolio
own operations.  The Portfolio may invest its assets in other money market funds
with comparable  investment  objectives.  In general,  the Portfolio may not (1)
purchase more than 3% of any other money market fund's voting stock;  (2) invest
more than 5% of its assets in any single money market fund;  and (3) invest more
than 10% of its assets in other money market  funds  unless  permitted to exceed
these limitations by an exemptive order of the SEC.

ILLIQUID SECURITIES

     While none of the ProFunds  anticipates  doing so, each of the ProFunds and
the Portfolio may purchase illiquid  securities,  including  securities that are
not readily  marketable  and  securities  that are not  registered  ("restricted
securities")  under the Securities Act of 1933, as amended (the "1933 Act"), but
which can be sold to qualified  institutional buyers under Rule 144A of the 1933
Act. A ProFund will not invest more than 15% (10% with respect to the Portfolio)
of the  ProFund's/Portfolio's  net  assets  in  illiquid  securities.  The  term
"illiquid  securities" for this purpose means securities that cannot be disposed
of within seven days in the  ordinary  course of business at  approximately  the
amount at which  the  ProFund  has  valued  the  securities.  Under the  current
guidelines  of  the  staff  of  the  Securities  and  Exchange  Commission  (the
"Commission"),illiquid  securities  also are considered to include,  among other
securities,    purchased    over-the-counter    options,   certain   cover   for
over-the-counter  options,  repurchase  agreements  with maturities in excess of
seven days, and certain  securities  whose  disposition is restricted  under the
Federal securities laws. The  ProFund/Portfolio may not be able to sell illiquid
securities  when the Advisor or Bankers Trust considers it desirable to do so or
may have to sell such  securities  at a price  that is lower than the price that
could be obtained if the securities were more liquid.  In addition,  the sale of
illiquid  securities  also may require more time and may result in higher dealer
discounts and other selling  expenses than does the sale of securities  that are
not illiquid. Illiquid securities also may be more difficult to value due to the
unavailability   of  reliable  market   quotations  for  such  securities,   and
investments  in  illiquid  securities  may have an  adverse  impact on net asset
value.
<PAGE>

     At the time of investment, the Portfolio's aggregate holdings of repurchase
agreements  having  remaining  maturities  of more than seven  calendar days (or
which may not be  terminated  within  seven  calendar  days  upon  notice by the
Portfolio),  time  deposits  having  remaining  maturities  of more  than  seven
calendar days, illiquid securities, restricted securities and securities lacking
readily  available market  quotations will not exceed 10% of the Portfolio's net
assets. If changes in the liquidity of certain securities cause the Portfolio to
exceed  such 10% limit,  the  Portfolio  will take steps to bring the  aggregate
amount of its  illiquid  securities  back below 10% of its net assets as soon as
practicable,  unless  such  action  would  not be in the  best  interest  of the
Portfolio.

     Institutional  markets for restricted securities have developed as a result
of the  promulgation  of Rule 144A  under the 1933 Act,  which  provides  a safe
harbor  from  1933  Act  registration   requirements  for  qualifying  sales  to
institutional  investors.  When  Rule  144A  restricted  securities  present  an
attractive  investment  opportunity  and otherwise  meet selection  criteria,  a
ProFund may make such  investments.  Whether or not such securities are illiquid
depends on the market that exists for the  particular  security.  The Commission
staff  has  taken  the  position  that the  liquidity  of Rule  144A  restricted
securities  is a question  of fact for a board of trustees  to  determine,  such
determination  to be based on a consideration of the  readily-available  trading
markets  and the  review of any  contractual  restrictions.  The staff  also has
acknowledged  that, while a board of trustees  retains ultimate  responsibility,
trustees  may  delegate  this  function to an  investment  adviser.  Trustees of
ProFunds have delegated this  responsibility  for  determining  the liquidity of
Rule 144A  restricted  securities  which may be  invested in by a ProFund to the
Advisor or, in the case of the Portfolio,  to Bankers Trust.  It is not possible
to predict  with  assurance  exactly  how the  market  for Rule 144A  restricted
securities or any other  security will develop.  A security which when purchased
enjoyed a fair degree of  marketability  may  subsequently  become illiquid and,
accordingly, a security which was deemed to be liquid at the time of acquisition
may subsequently become illiquid.  In such event,  appropriate  remedies will be
considered to minimize the effect on the ProFund's liquidity.

PORTFOLIO QUALITY AND MATURITY (MONEY MARKET PROFUND AND THE PORTFOLIO)

     The Portfolio will maintain a  dollar-weighted  average maturity of 90 days
or less. All securities in which the Portfolio invests will have or be deemed to
have  remaining  maturities  of 397 days or less on the date of their  purchase,
will be  denominated  in U.S.  dollars and will have been  granted the  required
ratings  established  herein by two  nationally  recognized  statistical  rating
organizations  ("NRSRO") (or one such NRSRO if that NRSRO is the only such NRSRO
which rates the security),  or if unrated,  are believed by Bankers Trust, under
the  supervision  of the  Portfolio's  Board of  Trustees,  to be of  comparable
quality. Currently, there are five rating agencies which have been designated by
the  Securities  and  Exchange   Commission  (the  "SEC")  as  an  NRSRO.  These
organizations  and their highest  short-term  rating category (which may also be
modified by a "+") are : Duff and Phelps  Credit  Rating Co.,  D-1;  Fitch IBCA,
Inc.,  F1;  Moody's  Investors  Service Inc.  ("Moody's"),  Prime-1;  Standard &
Poor's, A-1; and Thomson BankWatch,  Inc., T-1. A description of such ratings is
provided in the Appendix.  Bankers  Trust,  acting under the  supervision of and
procedures  adopted  by the  Board of  Trustees  of each  Portfolio,  will  also
determine that all securities  purchased by the Portfolio present minimal credit
risks. Bankers Trust will cause the Portfolio to dispose of any security as soon
as  practicable  if the security is no longer of the requisite  quality,  unless
such action would not be in the best interest of the Portfolio.
<PAGE>

OBLIGATIONS OF BANKS AND OTHER FINANCIAL INSTITUTIONS (MONEY MARKET PROFUND AND
THE PORTFOLIO)

         The  Portfolio  may  invest in U.S.  dollar-denominated  fixed  rate or
variable rate obligations of U.S. or foreign institutions, including banks which
are rated in the highest  short-term  rating  category by any two NRSROs (or one
NRSRO if that NRSRO is the only such NRSRO which rates such  obligations) or, if
not so rated, are believed by Bankers Trust, acting under the supervision of the
Board  of  Trustees  of  the  Portfolio,  to  be  of  comparable  quality.  Bank
obligations  in which the Portfolio  invests  include  certificates  of deposit,
bankers'   acceptances,   time  deposits,   commercial  paper,  and  other  U.S.
dollar-denominated  instruments  issued or  supported  by the credit of U.S.  or
foreign institutions including banks. For purposes of the Portfolio's investment
policies with respect to bank  obligations,  the assets of a bank will be deemed
to include the assets of its  domestic  and  foreign  branches.  Obligations  of
foreign  branches of U.S. banks and foreign banks may be general  obligations of
the parent bank in  addition to the issuing  bank or may be limited by the terms
of a specific obligation and by government regulation.  If Bankers Trust, acting
under  the  supervision  of  the  Portfolio's  Board  of  Trustees,   deems  the
instruments  to  present  minimal  credit  risk,  the  Portfolio  may  invest in
obligations  of foreign  banks or foreign  branches of U.S.  banks which include
banks located in the United  Kingdom,  Grand Cayman  Island,  Nassau,  Japan and
Canada.  Investments  in these  obligations  may entail risks that are different
from those of  investments  in  obligations  of U.S.  domestic  banks because of
differences in political,  regulatory and economic systems and conditions. These
risks include,  without limitation,  future political and economic developments,
currency  blockage,  the possible  imposition of  withholding  taxes on interest
payments,   possible  seizure  or  nationalization  of  foreign  deposits,   and
difficulty or inability of pursuing  legal  remedies and  obtaining  judgment in
foreign courts,  possible  establishment of exchange controls or the adoption of
other foreign governmental  restrictions that might affect adversely the payment
of principal and interest on bank  obligations.  Foreign  branches of U.S. banks
and foreign banks may also be subject to less stringent reserve requirements and
to different accounting,  auditing,  reporting and recordkeeping  standards than
those applicable to branches of U.S. banks. Under normal market conditions,  the
Portfolio  will invest  more than 25% of its assets in the foreign and  domestic
bank  obligations   described  above.  The  Portfolio's   concentration  of  its
investments  in bank  obligations  will cause the Portfolio to be subject to the
risks  peculiar to the  domestic  and foreign  banking  industries  to a greater
extent than if its investments  were not so  concentrated.  A description of the
ratings set forth above is provided in the Appendix.

COMMERCIAL  PAPER,  OTHER DEBT  OBLIGATIONS AND CREDIT  ENHANCEMENT  (MONEY
MARKET PROFUND AND THE PORTFOLIO)

     COMMERCIAL  PAPER.  The Portfolio may invest in fixed rate or variable rate
commercial paper, including variable rate master demand notes, issued by U.S. or
foreign entities. Commercial paper when purchased by the Portfolio must be rated
the highest  short-term  rating category by any two NRSROs (or one NRSRO if that
NRSRO is the only such NRSRO which rates the  obligation) or if not rated,  must
be believed  by Bankers  Trust,  acting  under the  supervision  of the Board of
Trustees of the Portfolio,  to be of comparable  quality.  Any commercial  paper
issued  by a  foreign  entity  and  purchased  by the  Portfolio  must  be  U.S.
dollar-denominated  and must not be subject to  foreign  withholding  tax at the
time of purchase. Investing in foreign commercial paper generally involves risks
similar to those  described  above  relating to  obligations of foreign banks or
foreign branches of U.S. banks.

     Variable rate master demand notes are unsecured instruments that permit the
indebtedness  thereunder  to vary and provide for  periodic  adjustments  in the
interest  rate.  Because  variable rate master  demand notes are direct  lending
arrangements between the Portfolio and the issuer, they are not normally traded.
Although no active  secondary  market may exist for these notes,  the  Portfolio
will purchase only those notes under which it may demand and receive  payment on
principal  and accrued  interest  daily or may resell the note to a third party.
While the notes are not typically  rated by credit rating  agencies,  issuers of
variable rate master demand notes must satisfy  Bankers Trust,  acting under the
supervision of the Board of Trustees of the  Portfolio,  that the same criterion
set forth above for issuers of commercial  paper are met. In the event an issuer
of a variable rate master demand note defaulted on its payment  obligation,  the
Portfolio  might be unable to  dispose of the note  because of the  absence of a
secondary market and could, for this or other reasons, suffer a loss to the full
extent of the default.  The face  maturities of variable rate notes subject to a
demand feature may exceed 397 days in certain circumstances.

     OTHER DEBT OBLIGATIONS.  The Portfolio may invest in deposits, bonds, notes
and debentures and other debt  obligations that at the time of purchase have, or
are comparable in priority and security to other securities of such issuer which
have,  outstanding  short-term  obligations  meeting the above short-term rating
requirements,  or if there are no such  short-term  ratings,  are  determined by
Bankers Trust,  acting under the supervision of the Board of Trustees,  to be of
comparable  quality and are rated in the top three highest long-term  categories
by the NRSROs rating such security.
<PAGE>

     CREDIT ENHANCEMENT.  Certain of the Portfolio's  acceptable investments may
be  credit-enhanced  by  a  guaranty,   letter  of  credit,  or  insurance.  Any
bankruptcy,  receivership, default, or change in the credit quality of the party
providing  the  credit   enhancement  will  adversely  affect  the  quality  and
marketability of the underlying security and could cause losses to the Portfolio
and affect the Money Market  ProFund's share price.  The Portfolio may have more
than 25% of its total assets invested in securities credit-enhanced by banks.

     ASSET-BACKED  SECURITIES.  The  Portfolio  may also  invest  in  securities
generally referred to as asset-backed  securities,  which directly or indirectly
represent a  participation  interest  in, or are secured by and payable  from, a
stream of payments  generated by  particular  assets,  such as motor  vehicle or
credit card receivables.  Asset-backed  securities may provide periodic payments
that consist of interest and/or principal payments. Consequently, the life of an
asset-backed  security  varies with the  prepayment  and loss  experience of the
underlying assets.

PORTFOLIO TURNOVER

     As  discussed  in  the  Prospectus,  the  ProFunds  anticipate  that  their
investors as part of their  strategy,  will  frequently  exchange  shares of the
ProFunds for shares in other ProFunds  pursuant to the exchange policy,  as well
as frequently redeem shares of the ProFunds (see "Shareholders'  Guide -- How to
Exchange Shares of the ProFunds" in the Prospectus).  The nature of the ProFunds
will cause the ProFunds to experience  substantial  portfolio turnover. A higher
portfolio turnover rate would likely involve  correspondingly  greater brokerage
commissions  and  transaction  and other  expenses  which  would be borne by the
ProFunds. In addition, a ProFund's portfolio turnover level may adversely affect
the ability of the ProFund to achieve its  investment  objective.  Because  each
ProFund's portfolio turnover rate to a great extent will depend on the purchase,
redemption, and exchange activity of the ProFund's investors, it is difficult to
estimate  what  the  ProFund's  actual  turnover  rate  will  be in the  future.
"Portfolio  Turnover  Rate" is defined under the rules of the  Commission as the
value of the securities  purchased or securities sold,  excluding all securities
whose  maturities at time of acquisition  were one year or less,  divided by the
average  monthly value of such securities  owned during the year.  Based on this
definition,  instruments  with  remaining  maturities  of less than one year are
excluded from the calculation of portfolio turnover rate.  Instruments  excluded
from the calculation of portfolio  turnover  generally would include the futures
contracts and option  contracts in which the non-money  market  ProFunds  invest
since such contracts  generally have a remaining maturity of less than one year.
Pursuant to the formula  prescribed by the  Commission,  the portfolio  turnover
rate for each ProFund is calculated  without  regard to  instruments,  including
options and futures contracts, having a maturity of less than one year. The Bull
ProFund,  the  UltraBull  ProFund,  the Bear ProFund and the  UltraBear  ProFund
typically  hold most of their  investments  in  short-term  options  and futures
contracts,  which,  therefore,  are excluded for purposes of computing portfolio
turnover.  Therefore, based on the Commission's portfolio turnover formula, each
of these ProFunds expects a portfolio turnover rate of approximately 0%.
<PAGE>

SPECIAL CONSIDERATIONS

     To the extent  discussed above and in the prospectus,  the ProFunds present
certain risks, some of which are further described below.

     TRACKING  ERROR.  While the  non-money  market  ProFunds do not expect that
their  returns  over  a  year  will  deviate  adversely  from  their  respective
benchmarks by more than ten percent, several factors may affect their ability to
achieve  this  correlation.  Among these  factors  are:  (1)  ProFund  expenses,
including  brokerage (which may be increased by high portfolio turnover) and the
cost of the investment techniques employed by the ProFunds; (2) less than all of
the  securities  in the  benchmark  being held by a ProFund and  securities  not
included in the benchmark being held by a ProFund; (3) an imperfect  correlation
between  the  performance  of  instruments  held by a  ProFund,  such as futures
contracts and options,  and the performance of the underlying  securities in the
cash  market;  (4)  bid-ask  spreads  (the effect of which may be  increased  by
portfolio turnover);  (5) holding instruments traded in a market that has become
illiquid or  disrupted;  (6) ProFund  share prices being  rounded to the nearest
cent; (7) changes to the benchmark  index that are not  disseminated in advance;
(8) the need to conform a ProFund's portfolio holdings to comply with investment
restrictions  or policies or regulatory or tax law  requirements,  and (9) early
and  unanticipated  closings of the  markets on which the  holdings of a ProFund
trade,  resulting in the inability of the ProFund to execute intended  portfolio
transactions.  While a close  correlation of any ProFund to its benchmark may be
achieved on any single trading day, over time the cumulative percentage increase
or  decrease  in the net asset  value of the  shares of a  ProFund  may  diverge
significantly  from  the  cumulative  percentage  decrease  or  increase  in the
benchmark due to a compounding effect.

     LEVERAGE.  The UltraBull ProFund, the UltraBear ProFund,  UltraOTC ProFund,
UltraEurope ProFund, UltraShort OTC ProFund and UltraShort Europe ProFund intend
to regularly use leveraged  investment  techniques in pursuing their  investment
objectives.  Utilization  of  leveraging  involves  special  risks and should be
considered to be speculative.  Leverage exists when a ProFund achieves the right
to a return on a capital base that exceeds the amount the ProFund has  invested.
Leverage  creates the  potential  for  greater  gains to  shareholders  of these
ProFunds during  favorable  market  conditions and the risk of magnified  losses
during adverse market conditions. Leverage should cause higher volatility of the
net asset values of these ProFunds' shares. Leverage may involve the creation of
a  liability  that does not  entail  any  interest  costs or the  creation  of a
liability  that  requires the ProFund to pay interest  which would  decrease the
ProFund's  total  return  to  shareholders.  If  these  ProFunds  achieve  their
investment  objectives,  during adverse market conditions,  shareholders  should
experience a loss of approximately twice the amount they would have incurred had
these ProFunds not been leveraged.

     NON-DIVERSIFIED    STATUS.    Each   non-money    market   ProFund   is   a
"non-diversified"   series.   A   non-money   market   ProFund   is   considered
"non-diversified"  because a relatively high percentage of the ProFund's  assets
may be  invested in the  securities  of a limited  number of issuers,  primarily
within the same economic sector. That ProFund's portfolio securities, therefore,
may be  more  susceptible  to any  single  economic,  political,  or  regulatory
occurrence  than  the  portfolio  securities  of a more  diversified  investment
company. A ProFund's  classification as a  "non-diversified"  investment company
means that the  proportion of the  ProFund's  assets that may be invested in the
securities  of a single  issuer is not  limited by the 1940 Act.  Each  ProFund,
however,  intends to seek to qualify as a  "regulated  investment  company"  for
purposes  of  the  Internal   Revenue  Code,   which   imposes   diversification
requirements on these ProFunds that are less  restrictive  than the requirements
applicable to the "diversified" investment companies under the 1940 Act.

SPECIAL INFORMATION CONCERNING MASTER-FEEDER FUND STRUCTURE

         Unlike other open-end  management  investment  companies (mutual funds)
which  directly  acquire and manage their own  portfolio  securities,  the Money
Market ProFund seeks to achieve its investment objective by investing all of its
assets in the Portfolio,  a separate registered investment company with the same
investment  objective  as the Money Market  ProFund.  Therefore,  an  investor's
interest in the  Portfolio's  securities  is indirect.  In addition to selling a
beneficial  interest  to the  Money  Market  ProFund,  the  Portfolio  may  sell
beneficial  interests  to other mutual funds or  institutional  investors.  Such
investors will invest in the Portfolio on the same terms and conditions and will
pay a  proportionate  share of the  Portfolio's  expenses.  However,  the  other
investors  investing in the  Portfolio  are not required to sell their shares at
the same  public  offering  price as the Money  Market  ProFund  or  subject  to
comparable  variations in sales loads and other operating  expenses.  Therefore,
investors in the Money Market ProFund should be aware that these differences may
result in differences in returns experienced by investors in the different funds
that may invest in the Portfolio.  Such  differences in returns are also present
in other  mutual  fund  structures.  Information  concerning  other  holders  of
interests in the Portfolio is available from Bankers Trust at 1-800-368-4031.
<PAGE>

     The ProFunds' Board of Trustees believes that the Money Market ProFund will
achieve certain  efficiencies  and economies of scale through the  master-feeder
structure,  and that the aggregate  expenses of the Money Market ProFund will be
less than if the Money Market ProFund  invested  directly in the securities held
by the Portfolio.

     Smaller funds investing in the Portfolio may be materially  affected by the
actions of larger funds investing in the Portfolio. For example, if a large fund
withdraws from the Portfolio, the remaining funds may experience higher pro rata
operating expenses,  thereby producing lower returns (however,  this possibility
exists as well for traditionally structured funds which have large institutional
investors).  Additionally,  the Portfolio may become less diverse,  resulting in
increased portfolio concentration and potential risk. Also, funds with a greater
pro rata ownership in the Portfolio  could have effective  voting control of the
operations of the Portfolio. Except as permitted by the Commission, whenever the
ProFunds  are  requested to vote on matters  pertaining  to the  Portfolio,  the
ProFunds  will hold a meeting of  shareholders  of the Money Market  ProFund and
will  cast all of its  votes in the same  proportion  as the  votes of the Money
Market ProFund's shareholders. Money Market ProFund shareholders who do not vote
will not affect the ProFunds votes at the Portfolio  meeting.  The percentage of
the Trust's votes representing Money Market ProFund shareholders not voting will
be voted by the Trustees or officers of the ProFunds in the same  proportion  as
the Money Market ProFund shareholders who do, in fact, vote.

     Certain  changes  in the  Portfolio's  investment  objective,  policies  or
restrictions  may require the Money  Market  ProFund to withdraw its interest in
the  Portfolio.  Such  withdrawal  could result in a  distribution  "in kind" of
portfolio securities (as opposed to a cash distribution from the Portfolio).  If
securities are distributed,  the Money Market ProFund could incur brokerage, tax
or other  charges  in  converting  the  securities  to cash.  In  addition,  the
distribution in kind may result in a less  diversified  portfolio of investments
or adversely  affect the liquidity of the Money Market ProFund.  Notwithstanding
the  above,  there are other  means for  meeting  redemption  requests,  such as
borrowing.

     The Money Market ProFund may withdraw its investment  from the Portfolio at
any time, if the Board of Trustees of the ProFunds  determines that it is in the
best  interests of the  shareholders  of the Money Market ProFund to do so. Upon
any such  withdrawal,  the Board of Trustees of the Trust  would  consider  what
action might be taken,  including the  investment of all the assets of the Money
Market ProFund in another pooled  investment  entity having the same  investment
objective as the Money Market ProFund or the retaining of an investment  adviser
to manage the Money Market  ProFund's  assets in accordance  with the investment
policies described above with respect to the Portfolio.

                             INVESTMENT RESTRICTIONS

     The ProFunds and the Portfolio have adopted certain investment restrictions
as  fundamental  policies  which  cannot be changed  without the approval of the
holders  of a  "majority"  of  the  outstanding  shares  of the  ProFund  or the
Portfolio,  as that term is  defined  in the 1940 Act.  The term  "majority"  is
defined  in the 1940 Act as the  lesser of: (i) 67% or more of the shares of the
series present at a meeting of shareholders,  if the holders of more than 50% of
the  outstanding  shares of the ProFund are present or represented by proxy;  or
(ii) more than 50% of the outstanding  shares of the series.  (All policies of a
ProFund not specifically  identified in this Statement of Additional Information
or  the  Prospectus  as  fundamental  may  be  changed  without  a  vote  of the
shareholders  of the ProFund.) For purposes of the  following  limitations,  all
percentage limitations apply immediately after a purchase or initial investment.

     A non-money market ProFund may not:

         1.       Invest  more  than 25% of its  total  assets,  taken at market
                  value at the time of each  investment,  in the  securities  of
                  issuers  in  any  particular   industry  (excluding  the  U.S.
                  government and its agencies and instrumentalities).

         2.       Make  investments  for the  purpose of  exercising  control or
                  management.

         3.       Purchase  or sell real  estate,  except  that,  to the  extent
                  permitted  by  applicable  law,  the  ProFund  may  invest  in
                  securities  directly or  indirectly  secured by real estate or
                  interests  therein or issued by companies  that invest in real
                  estate or interests therein.

         4.       Make loans to other  persons,  except that the  acquisition of
                  bonds,  debentures  or other  corporate  debt  securities  and
                  investment  in  government   obligations,   commercial  paper,
                  pass-through  instruments,  certificates of deposit,  bankers'
                  acceptances  and  repurchase  agreements and purchase and sale
                  contracts and any similar  instruments  shall not be deemed to
                  be the making of a loan,  and except  further that the ProFund
                  may lend its portfolio  securities,  provided that the lending
                  of portfolio  securities  may be made only in accordance  with
                  applicable  law and the guidelines set forth in the Prospectus
                  and this Statement of Additional  Information,  as they may be
                  amended from time to time.

         5.       Issue  senior  securities  to the extent such  issuance  would
                  violate applicable law.

         6.       Borrow  money,  except  that the  ProFund  (i) may borrow from
                  banks (as  defined in the  Investment  Company Act of 1940) in
                  amounts  up to 33  1/3% of its  total  assets  (including  the
                  amount  borrowed),  (ii)  may,  to  the  extent  permitted  by
                  applicable  law,  borrow up to an  additional  5% of its total
                  assets  for   temporary   purposes,   (iii)  may  obtain  such
                  short-term  credit as may be  necessary  for the  clearance of
                  purchases and sales of portfolio securities, (iv) may purchase
                  securities on margin to the extent permitted by applicable law
                  and (v) may enter  into  reverse  repurchase  agreements.  The
                  ProFund  may not pledge its assets  other than to secure  such
                  borrowings  or,  to the  extent  permitted  by  the  ProFund's
                  investment  policies as set forth in the  Prospectus  and this
                  Statement of Additional  Information,  as they may be amended
                  from time to time, in connection   with hedging  transactions,
                  short sales, when-issued and forward  commitment  transactions
                  and similar investment strategies.
<PAGE>

         7.       Underwrite securities of other issuers,  except insofar as the
                  ProFund  technically  may be deemed an  underwriter  under the
                  Securities Act of 1933, as amended (the "Securities  Act"), in
                  selling portfolio securities.

         8.       Purchase or sell  commodities  or  contracts  on  commodities,
                  except to the extent the ProFund may do so in accordance  with
                  applicable  law and the ProFund's  Prospectus and Statement of
                  Additional  Information,  as they may be amended  from time to
                  time.

     THE  FOLLOWING  FUNDAMENTAL  INVESTMENT  RESTRICTIONS  AND  NON-FUNDAMENTAL
INVESTMENT  OPERATING  POLICIES HAVE BEEN ADOPTED BY THE TRUST,  WITH RESPECT TO
THE MONEY MARKET PROFUND, AND BY THE PORTFOLIO.  UNLESS AN INVESTMENT INSTRUMENT
OR  TECHNIQUE  IS DESCRIBED IN THE  PROSPECTUS  OR ELSEWHERE  HEREIN,  THE MONEY
MARKET PROFUND AND THE PORTFOLIO MAY NOT INVEST IN THAT INVESTMENT INSTRUMENT OR
ENGAGE IN THAT INVESTMENT TECHNIQUE.

     The  investment  restrictions  below  have been  adopted  by the Trust with
respect to the Money Market ProFund and by the Portfolio as fundamental policies
(as defined above).  Whenever the Money Market ProFund is requested to vote on a
change in the investment  restrictions  of the Portfolio,  the Trust will hold a
meeting  of the Money  Market  ProFund  shareholders  and will cast its votes as
instructed by the shareholders. The Money Market ProFund shareholders who do not
vote will not affect the Trust's votes at the Portfolio meeting.  The percentage
of the Trust's votes representing  ProFund shareholders not voting will be voted
by the Trustees of the Trust in the same proportion as the Fund shareholders who
do, in fact, vote.

     Under  investment  policies  adopted by the Money Market ProFund and by the
Portfolio, each of the Money Market ProFund and Portfolio may not:

         1.       Borrow  money,   except  for   temporary  or  emergency   (not
                  leveraging)  purposes  in an amount  not  exceeding  5% of the
                  value  of  the  ProFund's  or  the  Portfolio's  total  assets
                  (including  the  amount   borrowed),   as  the  case  may  be,
                  calculated in each case at the lower of cost or market.

         2.       Pledge, hypothecate,  mortgage or otherwise encumber more than
                  5% of the total assets of the ProFund or the Portfolio, as the
                  case may be, and only to secure  borrowings  for  temporary or
                  emergency purposes.

         3.       Invest more than 5% of the total  assets of the ProFund or the
                  Portfolio,  as the case may be, in any one issuer  (other than
                  U.S. government  obligations) or purchase more than 10% of any
                  class of securities of any one issuer; provided, however, that
                  (i) up to 25% of the assets of the ProFund  and the  Portfolio
                  may be invested without regard to this restriction;  provided,
                  however,  that nothing in this  investment  restriction  shall
                  prevent  the Trust from  investing  all or part of a ProFund's
                  assets  in an  open-end  management  investment  company  with
                  substantially the same investment objectives as the ProFund.
<PAGE>


         4.       Invest more than 25% of the total assets of the ProFund or the
                  Portfolio, as the case may be, in the securities of issuers in
                  any single industry;  provided that: (i) this limitation shall
                  not apply to the purchase of U.S. government obligations; (ii)
                  under  normal  market  conditions  more  than 25% of the total
                  assets of the Money Market  ProFund and the Portfolio  will be
                  invested in  obligations  of U.S. and foreign  banks and other
                  financial  institutions Banks provided,  however, that nothing
                  in this  investment  restriction  shall  prevent a Trust  from
                  investing  all or part of a  ProFund's  assets in an  open-end
                  management  investment  company  with  substantially  the same
                  investment objectives as the ProFund.

         5.       Make short sales of  securities,  maintain a short position or
                  purchase any securities on margin,  except for such short-term
                  credits as are necessary for the clearance of transactions.

         6.       Underwrite  the  securities  issued by others  (except  to the
                  extent  the  ProFund  or  Portfolio  may  be  deemed  to be an
                  underwriter  under the Federal  securities  laws in connection
                  with the disposition of its portfolio securities) or knowingly
                  purchase  restricted  securities,   provided,   however,  that
                  nothing in this investment restriction shall prevent the Trust
                  from  investing  all of the  ProFund's  assets in an  open-end
                  management  investment  company  with  substantially  the same
                  investment objectives as the ProFund.

         7.       Purchase or sell real  estate,  real estate  investment  trust
                  securities, commodities or commodity contracts, or oil, gas or
                  mineral  interests,  but this shall not prevent the ProFund or
                  the Portfolio from  investing in  obligations  secured by real
                  estate or interests therein.

         8.       Make loans to others, except through the purchase of qualified
                  debt  obligations,  the entry into repurchase  agreements and,
                  with respect to the ProFund and the Portfolio,  the lending of
                  portfolio securities.

         9.       Invest more than an  aggregate of 10% of the net assets of the
                  ProFund  or the  Portfolio's,  respectively,  (taken,  in each
                  case,  at  current  value) in (i)  securities  that  cannot be
                  readily  resold to the public  because of legal or contractual
                  restrictions or because there are no market quotations readily
                  available or (ii) other "illiquid"  securities (including time
                  deposits and repurchase agreements maturing in more than seven
                  calendar  days);  provided,  however,  that  nothing  in  this
                  investment  restriction shall prevent the Trust from investing
                  all or part of the ProFund's assets in an open-end  management
                  investment  company  with  substantially  the same  investment
                  objective as the ProFund.

         10.      Purchase more than 10% of the voting  securities of any issuer
                  or invest in companies for the purpose of  exercising  control
                  or  management;   provided,  however,  that  nothing  in  this
                  investment  restriction shall prevent the Trust from investing
                  all or part of the ProFund's assets in an open-end  management
                  investment  company  with  substantially  the same  investment
                  objectives as the ProFund.
<PAGE>

         11.      Purchase securities of other investment  companies,  except to
                  the extent  permitted under the 1940 Act or in connection with
                  a merger, consolidation, reorganization, acquisition of assets
                  or an offer of exchange;  provided,  however,  that nothing in
                  this  investment  restriction  shall  prevent  the Trust  from
                  investing all or part of the  ProFunds'  assets in an open-end
                  management  investment  company  with  substantially  the same
                  investment objectives as the ProFund.

         12.      Issue  any  senior  securities,  except  insofar  as it may be
                  deemed  to have  issued a senior  security  by  reason  of (i)
                  entering into a reverse repurchase agreement or (ii) borrowing
                  in accordance  with terms described in the Prospectus and this
                  SAI.

         13.      Purchase or retain the  securities of any issuer if any of the
                  officers  or  trustees  of the  ProFund  or the  Portfolio  or
                  Bankers  Trust  owns  individually  more than 1/2 of 1% of the
                  securities  of such  issuer,  and together  such  officers and
                  directors own more than 5% of the securities of such issuer.

         14.      Invest in warrants,  except that the ProFund or the  Portfolio
                  may  invest  in  warrants  if, as a  result,  the  investments
                  (valued in each case at the lower of cost or market) would not
                  exceed 5% of the value of the net assets of the ProFund or the
                  Portfolio,  as the case may be,  of which  not more than 2% of
                  the net assets of the  ProFund or the  Portfolio,  as the case
                  may be, may be invested in warrants not listed on a recognized
                  domestic stock exchange.  Warrants  acquired by the ProFund or
                  the  Portfolio as part of a unit or attached to  securities at
                  the time of acquisition are not subject to this limitation.

     ADDITIONAL  RESTRICTIONS.  In order to comply  with  certain  statutes  and
policies,  the Portfolio (or, as applicable,  the Trust,  on behalf of the Money
Market  ProFund)  will not as a  matter  of  operating  policy  (except  that no
operating  policy shall prevent the ProFund from  investing all of its assets in
an  open-end   investment   company  with   substantially  the  same  investment
objective):


         (i)      borrow money (including  through dollar roll transactions) for
                  any  purpose in excess of 10% of the  Portfolio's  (ProFund's)
                  total  assets  (taken  at  cost),  except  that the  Portfolio
                  (ProFund) may borrow for temporary or emergency purposes up to
                  1/3 of its total assets;

         (ii)     pledge,  mortgage or hypothecate  for any purpose in excess of
                  10% of the  Portfolio's  (ProFund's)  total  assets  (taken at
                  market  value),  provided that  collateral  arrangements  with
                  respect to options and futures,  including deposits of initial
                  deposit and variation  margin,  are not considered a pledge of
                  assets for purposes of this restriction;
<PAGE>

         (iii)    purchase  any  security or  evidence  of  interest  therein on
                  margin, except that such short-term credit as may be necessary
                  for the clearance of purchases and sales of securities  may be
                  obtained  and except  that  deposits  of initial  deposit  and
                  variation  margin may be made in connection with the purchase,
                  ownership, holding or sale of futures;

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

         (v)      invest for the purpose of exercising control or management;

         (vi)     purchase securities issued by any investment company except by
                  purchase in the open market where no commission or profit to a
                  sponsor or dealer  results from such  purchase  other than the
                  customary broker's  commission,  or except when such purchase,
                  though  not  made  in the  open  market,  is part of a plan of
                  merger or consolidation; provided, however, that securities of
                  any investment company will not be purchased for the Portfolio
                  (ProFund) if such purchase at the time thereof would cause (a)
                  more  than 10% of the  Portfolio's  (ProFund's)  total  assets
                  (taken at the greater of cost or market  value) to be invested
                  in the  securities  of such  issuers;  (b) more than 5% of the
                  Portfolio's  (ProFund's) total assets (taken at the greater of
                  cost or market  value) to be  invested  in any one  investment
                  company;  or  (c)  more  than  3% of  the  outstanding  voting
                  securities  of any such  issuer  to be held for the  Portfolio
                  (ProFund); and, provided further, that the Portfolio shall not
                  invest in any other  open-end  investment  company  unless the
                  Portfolio  (ProFund)  (1) waives the  investment  advisory fee
                  with respect to assets  invested in other open-end  investment
                  companies  and (2) incurs no sales charge in  connection  with
                  the  investment (as an operating  policy,  each Portfolio will
                  not invest in another open-end registered investment company);

         (vii)    invest more than 15% of the Portfolio's  (ProFund's) total net
                  assets  (taken  at the  greater  of cost or  market  value) in
                  securities  that are  illiquid or not readily  marketable  not
                  including (a) Rule 144A  securities  that have been determined
                  to be  liquid  by the Board of  Trustees;  and (b)  commercial
                  paper that is sold under  section  4(2) of the 1933 Act which:
                  (i) is  not  traded  flat  or in  default  as to  interest  or
                  principal;  and  (ii)  is  rated  in one of  the  two  highest
                  categories by at least two nationally  recognized  statistical
                  rating  organizations;  (iii) is rated one of the two  highest
                  categories by one  nationally  recognized  statistical  rating
                  agency and the Portfolio's  (ProFund's) Board of Trustees have
                  determined that the commercial paper is equivalent quality and
                  is liquid;

          (viii)  with respect to 75% of the Portfolio's total assets,  purchase
                  securities  of any issuer if such purchase at the time thereof
                  would cause the  Portfolio  (ProFund) to hold more than 10% of
                  any class of securities of such issuer, for which purposes all
                  indebtedness  of an issuer  shall be deemed a single class and
                  all  preferred  stock of an  issuer  shall be  deemed a single
                  class,  except that futures or option  contracts  shall not be
                  subject to this restriction;
<PAGE>

          (ix)    if the  Portfolio is a  "diversified"  ProFund with respect to
                  75% of its assets,  invest more than 5% of its total assets in
                  the securities  (excluding U.S. government  securities) of any

                  unless at all times when a short  position  is open it owns an
                  equal amount of such securities or securities convertible into
                  or exchangeable, without payment of any further consideration,
                  for  securities  of the same issue and equal in amount to, the

                  into  or exchangeable  for such   securities,  at any one time
                  (the Portfolio  (ProFund) has  no current  intention to engage
                  in short selling).

         *With  respect to (ix) as an operating  policy,  the  Portfolio may not
invest  more than 5% of its total  assets in the  securities  of any one  issuer
except for U.S. government obligations and repurchase  agreements,  which may be
purchased without limitation.

     The Money  Market  ProFund will comply with the state  securities  laws and
regulations of all states in which it is  registered.  The Portfolio will comply
with the permitted investments and investment limitations in the securities laws
and  regulations of all states in which the Portfolio,  or any other  registered
investment company investing in the Portfolio, is registered.

DETERMINATION OF NET ASSET VALUE

     The net asset values of the shares of the ProFunds  (except the UltraEurope
ProFund and the  UltraShort  Europe  ProFund) are  determined as of the close of
business of the NYSE  (ordinarily,  4:00 p.m. Eastern Time) on each day the NYSE
and the Chicago  Mercantile  Exchange ("CME") are open for business (in the case
of the Money Market  ProFund,  net asset value is  determined as of the close of
business on each day the NYSE is open for business.)

     The net asset  values  of the  shares of the  UltraEurope  ProFund  and the
UltraShort  Europe  ProFund are  determined as of the latest close of trading on
the three  exchanges  tracked by the PEI  (ordinarily  11:30 AM Eastern Time) on
each day the NYSE,  London Stock  Exchange,  Frankfurt  Stock Exchange and Paris
Stock  Exchange are open for business (see  prospectus  for  applicable  holiday
closings).  To the extent that  portfolio  securities of a ProFund are traded in
other markets on days when the ProFund's  principal trading market(s) is closed,
the ProFund's net asset value may be affected on days when investors do not have
access to the ProFund to purchase or redeem shares. Although the ProFunds expect
the same  holiday  schedules  to be observed in the future,  the  exchanges  may
modify their holiday schedules at any time.
<PAGE>

     The net asset  value of each  class of  shares  of a ProFund  serves as the
basis for the purchase  and  redemption  price of that class of shares.  The net
asset value per share of each class of a ProFund is  calculated  by dividing the
market value of the ProFund's assets attributed to a specific class (in the case
of the Money Market ProFund, the value of its investment in the Portfolio), less
all  liabilities  attributed to the specific class, by the number of outstanding
shares of the class. If market quotations are not readily available,  a security
will be valued at fair value by the Trustees of ProFunds or by the Advisor using
methods  established  or ratified by the Trustees of ProFunds.  The Money Market
ProFund's  net asset  value  per  share  will  normally  be  $1.00.  There is no
assurance that the $1.00 net asset value will be maintained.

     The  Portfolio  will  utilize  the  amortized  cost  method in valuing  its
portfolio  securities.  This method  involves  valuing each security held by the
Portfolio  at its cost at the time of its  purchase  and  thereafter  assuming a
constant  amortization  to  maturity of any  discount  or premium.  Accordingly,
immaterial  fluctuations  in the  market  value  of the  securities  held by the
Portfolio  will not be reflected in the Money Market  ProFund's net asset value.
The Board of Trustees of the  Portfolio  will monitor the valuation of assets of
this method and will make such changes as it deems  necessary to assure that the
assets of the Portfolio are valued fairly in good faith.

     The securities in the portfolio of a non-money  market  ProFund,  except as
otherwise  noted,  that are listed or traded on a stock exchange,  are valued on
the basis of the last sale on that day or, lacking any sales, at a price that is
the mean between the closing bid and asked  prices.  Other  securities  that are
traded on the OTC markets are priced using NASDAQ, which provides information on
bid and asked prices quoted by major dealers in such stocks.  Bonds,  other than
convertible  bonds, are valued using a third-party  pricing system.  Convertible
bonds are valued  using this  pricing  system only on days when there is no sale
reported.  Short-term  debt securities are valued using this pricing system only
on days when there is no sale reported. Short-term debt securities are valued at
amortized cost, which approximates  market value. When market quotations are not
readily  available,  securities  and other  assets  are  valued at fair value as
determined in good faith under  procedures  established by and under the general
supervision and responsibility of the ProFunds' Board of Trustees.

     Except for the  UltraEurope  ProFund  and the  UltraShort  Europe  ProFund,
futures  contracts  are valued at their last sale price  prior to the  valuation
time.  Options  on  futures  contracts  generally  are  valued at fair  value as
determined with reference to establish future  exchanges.  Options on securities
and indices  purchased by a ProFund are valued at their last sale price prior to
the valuation time or at fair value.  In the event of a trading halt that closes
the NYSE  early,  futures  contracts  will be valued on the basis of  settlement
prices on futures exchanges,  options on futures will be valued at fair value as
determined with reference to such settlement  prices,  and options on securities
and indices will be valued at their last sale price prior to the trading halt or
at fair value.

     In the event a trading  halt closes a futures  exchange for a given day and
that  closure  occurs  prior  to the  close  of the  NYSE on that  day,  futures
contracts  will be  valued  on the basis of  settlement  prices  on the  futures
exchange or fair value.

     For the  UltraEurope  ProFund and the UltraShort  Europe  ProFund,  futures
contracts are valued at their last transaction prices for the respective futures
contracts  that occur  immediately  prior to the close of the  underlying  stock
exchange.  Options on futures  contracts  generally  are valued at fair value as
determined  with  reference  to  established   futures  exchanges.   Options  on
securities and indices purchased by these ProFunds are valued at their last sale
price immediately prior to the close of the underlying stock exchange.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

NON-MONEY MARKET PROFUNDS

     Subject  to  the  general  supervision  by the  Trustees,  the  Advisor  is
responsible  for decisions to buy and sell  securities for each of the ProFunds,
the  selection  of  brokers  and  dealers to effect  the  transactions,  and the
negotiation  of  brokerage  commissions,  if any.  The Advisor  expects that the
ProFunds 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.  The  Advisor  may  serve as an  investment  manager  to a number of
clients, including other investment companies. It is the practice of the Advisor
to cause purchase and sale  transactions  to be allocated among the ProFunds and
others  whose  assets the Advisor  manages in such  manner as the Advisor  deems
equitable. The main factors considered by the Advisor in making such allocations
among the ProFunds and other client  accounts of the Advisor are the  respective
investment  objectives,  the relative size of portfolio  holdings of the same or
comparable  securities,  the  availability of cash for  investment,  the size of
investment  commitments  generally  held,  and  the  opinions  of the  person(s)
responsible,  if any, for managing the  portfolios of the ProFunds and the other
client accounts.
<PAGE>

     The policy of each ProFund regarding  purchases and sales of securities for
a ProFund's  portfolio is that primary  consideration will be given to obtaining
the most favorable prices and efficient  executions of transactions.  Consistent
with this policy, when securities transactions are effected on a stock exchange,
each  ProFund's  policy  is to pay  commissions  which are  considered  fair and
reasonable without necessarily  determining that the lowest possible commissions
are paid in all  circumstances.  Each ProFund believes that a requirement always
to seek the lowest  possible  commission cost could impede  effective  portfolio
management  and  preclude  the  ProFund and the  Advisor  from  obtaining a high
quality  of  brokerage  and  research  services.  In seeking  to  determine  the
reasonableness  of brokerage  commissions paid in any  transaction,  the Advisor
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. Such determinations
are necessarily subjective and imprecise, as in most cases an exact dollar value
for those services is not ascertainable.

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

     In  seeking  to  implement  a  ProFund's  policies,   the  Advisor  effects
transactions with those brokers and dealers who the Advisor believes provide the
most favorable prices and are capable of providing efficient executions.  If the
Advisor  believes such prices and executions  are obtainable  from more than one
broker or dealer,  the  Advisor  may give  consideration  to  placing  portfolio
transactions  with those brokers and dealers who also furnish research and other
services to the ProFund or the Advisor.  Such services may include,  but are not
limited to, any one or more of 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.  If  the  broker-dealer  providing  these  additional
services is acting as a principal for its own account,  no commissions  would be
payable.  If the  broker-dealer is not a principal,  a higher  commission may be
justified, at the determination of the Advisor, for the additional services.

     The  information  and  services  received by the Advisor  from  brokers and
dealers may be of benefit to the Advisor in the  management  of accounts of some
of the  Advisor's  other  clients  and may not in all  cases  benefit  a ProFund
directly.  While the  receipt  of such  information  and  services  is useful in
varying  degrees and would  generally  reduce the amount of research or services
otherwise  performed by the Advisor and thereby  reduce the Advisor's  expenses,
this  information  and  these  services  are of  indeterminable  value  and  the
management  fee paid to the  Advisor is not  reduced  by any amount  that may be
attributable to the value of such information and services.

MONEY MARKET PROFUND AND THE PORTFOLIO

     Decisions to buy and sell  securities and other  financial  instruments for
the Money Market ProFund and the Portfolio are made by Bankers Trust, which also
is responsible for placing these transactions,  subject to the overall review of
the Portfolio's  Board of Trustees.  Although  investment  requirements  for the
Portfolio are reviewed independently from those of +++the other accounts managed
by Bankers Trust (the "Other Portfolios"), investments of the type the Portfolio
may make may also be made by these Other Portfolios.  When the Portfolio and one
or more Other  Portfolios  or accounts  managed by Bankers Trust are prepared to
invest  in,  or desire to  dispose  of,  the same  security  or other  financial
instrument,  available  investments or opportunities for sales will be allocated
in a manner  believed by Bankers  Trust to be equitable to each.  In some cases,
this procedure may affect  adversely the price paid or received by the Portfolio
or the size of the position obtained or disposed of by the Portfolio.

     Purchases and sales of  securities  on behalf of the Portfolio  usually are
principal  transactions.  These securities are normally  purchased directly from
the issuer or from an underwriter or market maker for the  securities.  The cost
of securities purchased from underwriters includes an underwriting commission or
concession  and the prices at which  securities  are purchased  from and sold to
dealers include a dealer's mark-up or mark-down. U.S. government obligations are
generally purchased from underwriters or dealers,  although certain newly issued
U.S. government  obligations may be purchased directly from the U.S. Treasury or
from the issuing agency or instrumentality.
<PAGE>

     Over-the-counter purchases and sales are transacted directly with principal
market makers except in those cases in which better prices and executions may be
obtained elsewhere and principal  transactions are not entered into with persons
affiliated  with the  Portfolios  except  pursuant to exemptive  rules or orders
adopted by the Commission. Under rules adopted by the Commission, broker-dealers
may not execute  transactions on the floor of any national  securities  exchange
for  the  accounts  of  affiliated  persons,  but  may  effect  transactions  by
transmitting orders for execution.

     In selecting brokers or dealers to execute portfolio transactions on behalf
of the  Portfolio,  Bankers  Trust seeks the best overall  terms  available.  In
assessing the best overall terms  available for any  transaction,  Bankers Trust
will consider the factors it deems relevant, including the breadth of the market
in the  investment,  the price of the  investment,  the financial  condition and
execution  capability  of the  broker or dealer  and the  reasonableness  of the
commission,  if any, for the specific  transaction and on a continuing basis. In
addition,  Bankers  Trust is  authorized,  in  selecting  parties  to  execute a
particular  transaction  and in evaluating  the best overall terms  available to
consider the brokerage, but not research services (as those terms are defined in
Section 28(e) of the  Securities  Exchange Act of 1934, as amended)  provided to
the Portfolio  involved,  the other Portfolios  and/or other accounts over which
Bankers Trust or its affiliates exercise investment discretion.  Bankers Trust's
fees under its  agreements  with the Portfolios are not reduced by reason of its
receiving brokerage services.

     The valuation of the  Portfolio's  securities  is based on their  amortized
cost,  which  does not take into  account  unrealized  capital  gains or losses.
Amortized cost valuation  involves  initially  valuing an instrument at its cost
and thereafter  assuming a constant  amortization to maturity of any discount or
premium, generally without regard to the impact of fluctuating interest rates on
the market value of the instrument.  Although this method provides  certainty in
valuation,  it may  result in periods  during  which  value,  as  determined  by
amortized  cost, is higher or lower than the price a Portfolio  would receive if
it sold the instrument.

     The  Portfolio's use of the amortized cost method of valuing its securities
is permitted by a rule adopted by the Commission. Under this rule, the Portfolio
must maintain a dollar-weighted  average portfolio  maturity of 90 days or less,
purchase only instruments having remaining  maturities of 397 days or and invest
only in  securities  determined  by or under  the  supervision  of the  Board of
Trustees to be of high quality with minimal credit risks.

     Pursuant  to the rule,  the Board of  Trustees  of the  Portfolio  also has
established procedures designed to allow investors in the Portfolio, such as the
Money Market  ProFund,  to stabilize,  to the extent  reasonably  possible,  the
investors'  price per share as computed for the purpose of sales and redemptions
at $1.00.  These  procedures  include review of the Portfolio's  holdings by the
Portfolio's  Board of Trustees,  at such intervals as it deems  appropriate,  to
determine  whether  the  value of the  Portfolio's  assets  calculated  by using
available market quotations or market  equivalents  deviates from such valuation
based on amortized cost.

         The rule also  provides  that the extent of any  deviation  between the
value of the Portfolio's  assets based on available market  quotations or market
equivalents  and such valuation  based on amortized cost must be examined by the
Portfolio's  Board of Trustees.  In the event the Portfolio's  Board of Trustees
determines that a deviation exists that may result in material dilution or other
unfair results to investors or existing shareholders,  pursuant to the rule, the
Portfolio's  Board of Trustees must cause the Portfolio to take such  corrective
action  as  such  Board  of  Trustees  regards  as  necessary  and  appropriate,
including:  selling  portfolio  instruments prior to maturity to realize capital
gains or losses or to shorten average portfolio maturity;  withholding dividends
or paying distributions from capital or capital gains; redeeming shares in kind;
or valuing the Portfolio's assets by using available market quotations.
<PAGE>

     Each investor in the Portfolio, including the Money Market ProFund, may add
to or  reduce  its  investment  in the  Portfolio  on  each  day  the  Portfolio
determines its Net Asset Value ("NAV").  At the close of each such business day,
the  value of each  investor's  beneficial  interest  in the  Portfolio  will be
determined by multiplying the NAV of the Portfolio by the percentage,  effective
for that day, which represents that investor's share of the aggregate beneficial
interests  in the  Portfolio.  Any  additions  or  withdrawals,  which are to be
effected  as of the close of business on that day,  will then be  effected.  The
investor's  percentage  of the aggregate  beneficial  interests in the Portfolio
will  then  be  recomputed  as the  percentage  equal  to the  fraction  (i) the
numerator of which is the value of such  investor's  investment in the Portfolio
as of the close of business  on such day plus or minus,  as the case may be, the
amount of net additions to or withdrawals from the investor's  investment in the
Portfolio  effected  as of the  close  of  business  on such  day,  and (ii) the
denominator  of which is the  aggregate  NAV of the Portfolio as of the close of
business  on such day plus or  minus,  as the case  may be,  the  amount  of net
additions to or withdrawals  from the aggregate  investments in the Portfolio by
all  investors in the  Portfolio.  The  percentage  so  determined  will then be
applied to determine the value of the investor's interest in the Portfolio as of
the close of the following business day.

     For the fiscal year ended December 31, 1998,  each  non-money  ProFund paid
brokerage commissions in the following amount:

Authorized  Firms that purchase  Service Shares on behalf of their clients.  The
Shareholder  Services Agreements will provide for compensation to the Authorized
Firms in an amount up to 1.00% (on an  annual  basis) of the  average  daily net
assets of the Service shares of the applicable  ProFund  attributable to or held
in the  name of the  Authorized  Firm  for its  clients.  The  ProFunds  may pay
different service fee amounts to Authorized  Firms,  which may provide different
levels of services to their clients or customers.

     The Trustees of the Trust, including a majority of the Trustees who are not
interested  persons  of the Trust and who have no direct or  indirect  financial
interest  in the  operation  of the  Plan or the  related  Shareholder  Services
Agreements,  voted to adopt the Plan and  Shareholder  Services  Agreements at a
meeting called for the purpose of voting on such Plan and  Shareholder  Services
Agreements on October 28, 1997.  The Plan and  Shareholder  Services  Agreements
will  remain in  effect  for a period  of one year and will  continue  in effect
thereafter only if such continuance is specifically  approved annually by a vote
of the Trustees in the manner described  above.  All material  amendments of the
Plan must also be approved by the Trustees in the manner  described  above.  The
Plan may be  terminated  at any time by a majority of the  Trustees as described
above or by vote of a majority of the outstanding Service shares of the affected
ProFund.  The  Shareholder  Services  Agreements  may be terminated at any time,
without  payment  of any  penalty,  by vote of a  majority  of the  Trustees  as
described above or by a vote of a majority of the outstanding  Service Shares of
the affected ProFund on not more than 60 days' written notice to any other party
to the Shareholder  Services  Agreements.  The Shareholder  Services  Agreements
shall terminate automatically if assigned. The Trustees have determined that, in
their judgment,  there is a reasonable likelihood that the Plan will benefit the
ProFunds  and  holders  of Service  shares of such  ProFunds.  In the  Trustees'
quarterly  review of the Plan and  Shareholder  Services  Agreements,  they will
consider their continued  appropriateness and the level of compensation provided
therein.
<PAGE>

     The intent of the Plan and  Shareholder  Services  Agreements is to procure
quality shareholder services on behalf of ProFund shareholders;  in adopting the
Plan and Shareholder Services Agreements,  the Trustees considered the fact that
such  shareholder  services  may have the effect of  enhancing  distribution  of
ProFund  Service  shares  and  growth  of the  ProFunds.  In light of this,  the
ProFunds  intend to observe the procedural  requirements of Rule 12b-1 under the
1940  Act  on  considering  the  continued   appropriateness  of  the  Plan  and
Shareholder Services Agreements.

     For the fiscal years ended  December 31, 1997 and 1998,  each ProFund paid,
unless voluntarily waived,  shareholder services fees to authorized firms in the
following amounts:

                               COSTS AND EXPENSES

     Each ProFund bears all expenses of its operations  other than those assumed
by the Advisor or the  Administrator.  ProFund expenses include:  the management
fee;  the  servicing  fee  (including   administrative,   transfer  agent,   and
shareholder servicing fees);  custodian and accounting fees and expenses,  legal
and auditing  fees;  securities  valuation  expenses;  fidelity  bonds and other
insurance   premiums;   expenses  of  preparing   and   printing   prospectuses,
confirmations,   proxy   statements,   and  shareholder   reports  and  notices;
registration  Trustees and expenses;  proxy and annual meeting expenses, if any;
all Federal,  state,  and local taxes  (including,  without  limitation,  stamp,
excise,  income, and franchise taxes);  organizational costs; and non-interested
Trustees' fees and expenses.

          ORGANIZATION AND DESCRIPTION OF SHARES OF BENEFICIAL INTEREST

     ProFunds (the "Trust") is a registered  open-end  investment  company under
the 1940 Act. The Trust was organized as a Delaware  business trust on April 17,
1997, and has authorized  capital of unlimited shares of beneficial  interest of
no par value  which may be issued in more than one class or  series.  Currently,
the Trust consists of six separately  managed series.  Other separate series may
be added in the future.  Each ProFund offers two classes of shares:  the Service
Shares and the Investor Shares.
<PAGE>

     All shares of the ProFund are freely transferable.  The Trust shares do not
have preemptive rights or cumulative voting rights,  and none of the shares have
any preference to conversion,  exchange,  dividends,  retirements,  liquidation,
redemption,  or any other feature. Trust shares have equal voting rights, except
that, in a matter affecting a particular series or class of shares,  only shares
of that series or class may be entitled to vote on the matter.

     Under   Delaware  law,  the  Trust  is  not  required  to  hold  an  annual
shareholders meeting if the 1940 Act does not require such a meeting. Generally,
there will not be annual meetings of Trust shareholders.  Trust shareholders may
remove Trustees from office by votes cast at a meeting of Trust  shareholders or
by  written  consent.  If  requested  by  shareholders  of at  least  10% of the
outstanding  shares of the Trust,  the Trust  will call a meeting  of  ProFunds'
shareholders for the purpose of voting upon the question of removal of a Trustee
of the Trust and will assist in communications with other Trust shareholders.

     The  Declaration  of  Trust  of the  ProFunds  disclaims  liability  of the
shareholders  or the officers of the Trust for acts or  obligations of the Trust
which are binding only on the assets and property of the Trust.  The Declaration
of Trust provides for  indemnification  of the Trust's property for all loss and
expense of any ProFunds  shareholder held personally  liable for the obligations
of the  Trust.  The  risk of a Trust  shareholder  incurring  financial  loss on
account of shareholder  liability is limited to  circumstances  in which loss of
account  of  shareholder  liability  is limited  to  circumstances  in which the
ProFunds itself would not be able to meet the Trust's obligations and this risk,
thus, should be considered remote.

                                 CAPITALIZATION

     As of February 16, 1999, no person owned of record,  or to the knowledge of
management  beneficially owned five percent or more of the outstanding shares of
the ProFunds or classes except as set forth below:

                                    TAXATION

     Set forth below is a discussion of certain U.S.  federal  income tax issues
concerning the ProFunds and the purchase,  ownership, and disposition of ProFund
shares.  This  discussion  does not  purport to be  complete or to deal with all
aspects of federal income taxation that may be relevant to shareholders in light
of their particular circumstances,  nor to certain types of shareholders subject
to special  treatment under the federal income tax laws (for example,  banks and
life insurance  companies).  This discussion is based upon present provisions of
the Internal  Revenue Code of 1986,  as amended (the  "Code"),  the  regulations
promulgated thereunder, and judicial and administrative ruling authorities,  all
of which are subject to change,  which  change may be  retroactive.  Prospective
investors  should  consult their own tax advisors with regard to the federal tax
consequences of the purchase,  ownership,  or disposition of ProFund shares,  as
well as the tax  consequences  arising  under  the  laws of any  state,  foreign
country, or other taxing jurisdiction.

     Dividends out of net ordinary  income and  distribution  of net  short-term
capital gains are taxable to the recipient U.S. shareholders as ordinary income,
whether  received in cash or reinvested in ProFund  shares.  Dividends  from net
ordinary income may be eligible for the corporate dividends-received deduction.

     The excess of net long-term  capital gains over the net short-term  capital
losses realized and distributed by a ProFund to its U.S. shareholders as capital
gains  distributions  is taxable to the  shareholders as gain from the sale of a
capital  asset held for more than one year,  regardless  of the length of time a
shareholder has held the ProFund shares.  If a shareholder  holds ProFund shares
for six months or less and during that period receives a distribution taxable to
the shareholder as long-term  capital gain, any loss realized on the sale of the
ProFund shares will be long-term loss to the extent of such distribution.

     The amount of an income dividend or capital gains distribution  declared by
a ProFund  during  October,  November or December  of a year to  shareholder  of
record as of a specified date in such a month that is paid during January of the
following year will be deemed to be received by  shareholders  on December 31 of
the prior year.

     Any dividend or  distribution  paid by a ProFund has the effect of reducing
the ProFund's net asset value per share. Investors should be careful to consider
the tax effect of buying shares shortly before a distribution by a ProFund.  The
price  of  shares  purchased  at  that  time  will  include  the  amount  of the
forthcoming   distribution,   but  the  distribution  will  be  taxable  to  the
shareholder.
<PAGE>

     A  dividend  or  capital  gains  distribution  with  respect to shares of a
ProFund held by a tax-deferred  or qualified  plan,  such as an IRA,  retirement
plan or corporate  pension or profit  sharing  plan,  will not be taxable to the
plan.  Distribution  from such plans will be taxable to individual  participants
under  applicable tax rules without regard to the character of the income earned
by the qualified plan.

     Shareholders  will be  advised  annually  as to the  federal  tax status of
dividends and capital gains  distribution made by the ProFunds for the preceding
year.  Distributions  by ProFunds  generally  will be subject to state and local
taxes.

     Each of the  ProFunds  intends to qualify and elect to be treated each year
as a regulated  investment  company (a "RIC") under  Subchapter M of the Code. A
RIC  generally  is not  subject  to  federal  income  tax on  income  and  gains
distributed in a timely manner to its  shareholders.  Accordingly,  each ProFund
generally must, among other things, (a) derive in each taxable year at least 90%
of its gross income from dividends,  interest,  payments with respect to certain
securities  loans,  and  gains  from  the sale or other  disposition  of  stock,
securities or foreign  currencies,  or other income  derived with respect to its
business of investing in such stock, securities or currencies; and (b) diversify
its holdings so that, at the end of each fiscal quarter, (i) at least 50% of the
market value of the ProFund's  assets is  represented by cash,  U.S.  government
securities,  the securities of other  regulated  investment  companies and other
securities, with such other securities limited, in respect of any one issuer, to
an amount not greater than 5% of the value of the ProFund's total assets and 10%
of the outstanding  voting securities of such issuer, and (ii) not more than 25%
of the value of its total assets is invested in the securities of any one issuer
(other than U.S.  government  securities and the  securities of other  regulated
investment companies).

     As a regulated  investment company, a ProFund generally will not be subject
to  U.S.  federal  income  tax on  income  and  gains  that  it  distributes  to
shareholders, if at least 90% of the ProFund's investment company taxable income
(which includes,  among other items,  dividends,  interest and the excess of any
net short-term  capital gains over net long-term capital losses) for the taxable
year is  distributed.  Each ProFund intends to distribute  substantially  all of
such income.

     Amounts not  distributed  on a timely basis in  accordance  with a calendar
year  distribution  requirement are subject to a nondeductible  4% excise tax at
the ProFund level.  To avoid the tax, each ProFund must  distribute  during each
calendar  year an amount  equal to the sum of (1) at least  98% of its  ordinary
income (not taking into  account any capital  gains or losses) for the  calendar
year,  (2) at least 98% of its  capital  gains in excess of its  capital  losses
(adjusted for certain ordinary losses) for a one-year period generally ending on
October 31 of the calendar year,  and (3) all ordinary  income and capital gains
for  previous  years  that were not  distributed  during  such  years.  To avoid
application  of the excise tax, the  ProFunds  intend to make  distributions  in
accordance with the calendar year distribution requirement.  A distribution will
be treated as paid on  December  31 of a calendar  year if it is declared by the
ProFund in October, November or December of that year with a record date in such
a month and paid by the  ProFund  during  January of the  following  year.  Such
distributions  will be taxable to shareholders in the calendar year in which the
distributions  are  declared,  rather  than  the  calendar  year  in  which  the
distributions are received.

MARKET DISCOUNT

     If  ProFund  purchases  a debt  security  at a price  lower than the stated
redemption  price of such debt  security,  the excess of the  stated  redemption
price  over the  purchase  price is "market  discount".  If the amount of market
discount is more than a de minimis  amount,  a portion of such  market  discount
must be included as ordinary  income (not  capital  gain) by the ProFund in each
taxable  year in which the ProFund  owns an interest in such debt  security  and
receives a principal payment on it. In particular,  the ProFund will be required
to allocate that principal  payment first to the portion of the market  discount
on the debt security that has accrued but has not previously  been includable in
income. In general, the amount of market discount that must be included for each
period is equal to the  lesser of (i) the  amount  of market  discount  accruing
during  such period  (plus any accrued  market  discount  for prior  periods not
previously taken into account) or (ii) the amount of the principal  payment with
respect to such period. Generally,  market discount accrues on a daily basis for
each day the debt security is held by a ProFund at a constant rate over the time
remaining to the debt security's maturity or, at the election of the ProFund, at
a  constant  yield  to  maturity  which  takes  into  account  the   semi-annual
compounding of interest.  Gain realized on the  disposition of a market discount
obligation must be recognized as ordinary  interest income (not capital gain) to
the extent of the "accrued market discount."
<PAGE>

ORIGINAL ISSUE DISCOUNT

     Certain  debt  securities  acquired by the  ProFunds may be treated as debt
securities  that were originally  issued at a discount.  Original issue discount
can generally be defined as the difference between the price at which a security
was issued and its stated redemption price at maturity.  Although no cash income
is actually  received by a ProFund,  original  issue  discount that accrues on a
debt  security  in a given year  generally  is treated  for  federal  income tax
purposes  as  interest  and,  therefore,  such  income  would be  subject to the
distribution requirements applicable to regulated investment companies.

     Some debt  securities  may be purchased by the ProFunds at a discount  that
exceeds the  original  issue  discount  on such debt  securities,  if any.  This
additional  discount  represents market discount for federal income tax purposes
(see above).

OPTIONS, FUTURES AND FOREIGN CURRENCY FORWARD CONTRACTS

     Any Regulated  futures  contracts and certain  options  (namely,  nonequity
options and dealer equity options) in which a ProFund may invest may be "section
1256 contracts."  Gains (or losses) on these contracts  generally are considered
to be 60% long-term and 40% short-term capital gains or losses;  however foreign
currency  gains or losses  arising  from  certain  section  1256  contracts  are
ordinary in character. Also, section 1256 contracts held by a ProFund at the end
of each taxable  year (and on certain  other dates  prescribed  in the Code) are
"marked to market" with the result that  unrealized  gains or losses are treated
as though they were realized.

     Transactions in options,  futures and forward  contracts  undertaken by the
ProFunds may result in "straddles" for federal income tax purposes. The straddle
rules may affect the character of gains (or losses)  realized by a ProFund,  and
losses  realized by the ProFund on positions  that are part of a straddle may be
deferred  under the  straddle  rules,  rather than being  taken into  account in
calculating  the  taxable  income for the  taxable  year in which the losses are
realized.  In addition,  certain carrying charges  (including  interest expense)
associated with positions in a straddle may be required to be capitalized rather
than deducted currently.  Certain elections that a ProFund may make with respect
to its straddle  positions  may also affect the amount,  character and timing of
the recognition of gains or losses from the affected positions.

     Because only a few  regulations  implementing  the straddle rules have been
promulgated,  the  consequences  of such  transactions  to the  ProFunds are not
entirely clear. The straddle rules may increase the amount of short-term capital
gain realized by a ProFund,  which is taxed as ordinary income when  distributed
to  shareholders.  Because  application  of the  straddle  rules may  affect the
character of gains or losses,  defer losses and/or accelerate the recognition of
gains or losses from the affected straddle  positions,  the amount which must be
distributed to shareholders as ordinary income or long-term  capital gain may be
increased or decreased  substantially  as compared to a fund that did not engage
in such transactions.

CONSTRUCTIVE SALES

     Recently  enacted  rules may affect the timing and  character  of gain if a
ProFund engages in  transactions  that reduce or eliminate its risk of loss with
respect to appreciated  financial positions.  If the ProFund enters into certain
transactions in property while holding  substantially  identical  property,  the
ProFund  would be  treated  as if it had sold and  immediately  repurchased  the
property  and would be taxed on any gain (but not  loss)  from the  constructive
sale.  The  character  of gain from a  constructive  sale would  depend upon the
ProFund's holding period in the property. Loss from a constructive sale would be
recognized  when the property was  subsequently  disposed of, and its  character
would depend on the ProFund's holding period and the application of various loss
deferral provisions of the Code.
<PAGE>

PASSIVE FOREIGN INVESTMENT COMPANIES

     The  ProFund  may  invest  in shares of  foreign  corporations  that may be
classified under the Code as passive foreign investment companies ("PFICs").  In
general,  a foreign  corporation is classified as a PFIC if at least one-half of
its assets constitute investment-type assets, or 75% or more of its gross income
is   investment-type   income.   If  a  ProFund  receives  a  so-called  "excess
distribution" with respect to PFIC stock, the ProFund itself may be subject to a
tax on a portion of the excess  distribution,  whether or not the  corresponding
income is distributed by the ProFund to shareholders. In general, under the PFIC
rules, an excess  distribution  is treated as having been realized  ratably over
the period  during  which the ProFund  held the PFIC  shares.  Each ProFund will
itself be subject to tax on the portion,  if any, of an excess distribution that
is so allocated to prior ProFund  taxable  years and an interest  factor will be
added to the tax, as if the tax had been  payable in such prior  taxable  years.
Certain  distributions  from a PFIC as well as gain from the sale of PFIC shares
are treated as excess  distributions.  Excess distributions are characterized as
ordinary  income even  though,  absent  application  of the PFIC rules,  certain
excess distributions might have been classified as capital gains.

     The ProFund may be eligible to elect alternative tax treatment with respect
to  PFIC  shares.  Under  an  election  that  currently  is  available  in  some
circumstances,  a ProFund  generally  would be  required to include in its gross
income its share of the  earnings of a PFIC on a current  basis,  regardless  of
whether  distributions  were  received  from the PFIC in a given  year.  If this
election were made, the special rules, discussed above, relating to the taxation
of excess  distributions,  would not apply. In addition,  another election would
involve  marking to market the ProFund's  PFIC shares at the end of each taxable
year, with the result that unrealized gains would be treated as though they were
realized and reported as ordinary income. Any mark-to-market losses and any loss
from an actual  disposition  of ProFund  shares would be  deductible as ordinary
losses to the extent of any net mark-to-market gains included in income in prior
years.

DISTRIBUTIONS

     Distributions  of investment  company  taxable income are taxable to a U.S.
shareholder as ordinary income,  whether paid in cash or shares.  Dividends paid
by a ProFund to a  corporate  shareholder,  to the  extent  such  dividends  are
attributable to dividends  received from U.S.  corporations by the ProFund,  may
qualify for the dividends received deduction.  However,  the revised alternative
minimum tax  applicable  to  corporations  may deduct the value of the dividends
received  deduction.  Distributions  of net  capital  gains  (the  excess of net
long-term capital gains over net short-term capital losses),  if any, designated
by the ProFund as capital gain dividends, whether paid in cash or in shares, are
taxable  as gain from the sale or  exchange  of an asset  held for more than one
year,  regardless of how long the  shareholder  has held the  ProFund's  shares.
Capital gains dividends are not eligible for the dividends received deduction.

     Shareholders will be notified annually as to the U.S. federal tax status of
distributions,  and  shareholders  receiving  distributions in the form of newly
issued  shares  will  receive a report as to the net asset  value of the  shares
received.

     If the net asset value of shares is reduced below a shareholder's cost as a
result of a  distribution  by a ProFund,  such  distribution  generally  will be
taxable even though it represents a return of invested capital. Investors should
be careful to consider the tax  implications  of buying shares of a ProFund just
prior to a distribution. The price of shares purchased at this time will include
the amount of the forthcoming distribution,  but the distribution will generally
be taxable.

     If a  shareholder  has chosen to  receive  distributions  in cash,  and the
postal ( or other  delivery  )  service  is  unable  to  deliver  checks  to the
shareholder's address of record, ProFunds will change the distribution option so
that all  distributions  are  automatically  reinvested  in  additional  shares.
ProFunds will not pay interest on uncashed distribution checks.
<PAGE>


DISPOSITION OF SHARES

     Upon a redemption,  sale or exchange of shares of a ProFund,  a shareholder
will  realize  a  taxable  gain or loss  depending  upon his or her basis in the
shares. A gain or loss will be treated as capital gain or loss if the shares are
capital  assets in the  shareholder's  hands and  generally  will be  long-term,
mid-term or short-term,  depending upon the shareholder's holding period for the
shares.  Any loss realized on a redemption,  sale or exchange will be disallowed
to  the  extent  the  shares  disposed  of  are  replaced   (including   through
reinvestment of dividends) within a period of 61 days,  beginning 30 days before
and ending 30 days after the shares are disposed of. In such a case the basis of
the shares  acquired will be adjusted to reflect the  disallowed  loss. Any loss
realized by a shareholder on the  disposition of a ProFund's  shares held by the
shareholder  for six  months  or less  will be  treated  for tax  purposes  as a
long-term  capital  loss to the  extent of any  distributions  of  capital  gain
dividends  received or treated as having been received by the  shareholder  with
respect to such shares.

BACKUP WITHHOLDING

     Each ProFund generally will be required to withhold federal income tax at a
rate  of  31%  ("backup   withholding")   from  dividends  paid,   capital  gain
distributions,  and redemption  proceeds to  shareholders if (1) the shareholder
fails  to  furnish  the  ProFund  with  the   shareholder's   correct   taxpayer
identification  number or  social  security  number,  (2) the IRS  notifies  the
shareholder or the ProFund that the  shareholder  has failed to report  properly
certain  interest  and  dividend  income to the IRS and to respond to notices to
that effect,  or (3) when  required to do so, the  shareholder  fails to certify
that he or she is not subject to backup withholding. Any amounts withheld may be
credited against the shareholder's federal income tax liability.

OTHER TAXATION

     Distributions may be subject to additional state,  local and foreign taxes,
depending on each shareholder's particular situation.  Non-U.S. shareholders and
certain types of U.S.  shareholders  subject to special treatment under the U.S.
federal income tax laws (e.g. banks and life insurance companies) may be subject
to U.S. tax rules that differ significantly from those summarized above.

EQUALIZATION ACCOUNTING

     Each ProFund  distributes  its net  investment  income and capital gains to
shareholders  as  dividends  annually  to the  extent  required  to qualify as a
regulated  investment  company  under the Code and  generally  to avoid  federal
income or excise tax.  Under  current  law,  each  ProFund may on its tax return
treat as a  distribution  of investment  company  taxable income and net capital
gain the portion of  redemption  proceeds  paid to redeeming  shareholders  that
represents the redeeming  shareholders'  portion of the ProFund's  undistributed
investment  company  taxable income and net capital gain.  This practice,  which
involves the use of  equalization  accounting,  will have the effect of reducing
the amount of income and gains that the  ProFund is required  to  distribute  as
dividends to  shareholders  in order for the ProFund to avoid federal income tax
and excise  tax.  This  practice  may also  reduce  the amount of  distributions
required  to be  made  to  nonredeeming  shareholders  and  the  amount  of  any
undistributed income will be reflected in the value of the ProFund's shares; the
total return on a  shareholder's  investment  will not be reduced as a result of
the ProFund's distribution policy.  Investors who purchase shares shortly before
the  record  date of a  distribution  will pay the full price for the shares and
then receive some portion of the price back as a taxable distribution.

                             PERFORMANCE INFORMATION

TOTAL RETURN CALCULATIONS

     From time to time, each of the non-money  market ProFunds may advertise the
total  return of the ProFund for prior  periods.  Any such  advertisement  would
include at least  average  annual total return  quotations  for one,  five,  and
ten-year periods, or for the life of the ProFund. Other total return quotations,
aggregate  or  average,  over other time  periods  for the  ProFund  also may be
included.
<PAGE>

     The total  return of a  ProFund  for a  particular  period  represents  the
increase (or decrease) in the value of a hypothetical  investment in the ProFund
from the  beginning  to the end of the period.  Total  return is  calculated  by
subtracting  the  value of the  initial  investment  from the  ending  value and
showing  the  difference  as  a  percentage  of  the  initial  investment;  this
calculation assumes that the initial investment is made at the current net asset
value and that all income  dividends or capital gains  distributions  during the
period are reinvested in shares of the ProFund at net asset value.  Total return
is based on historical earnings and asset value fluctuations and is not intended
to indicate  future  performance.  No adjustments are made to reflect any income
taxes  payable  by  shareholders  on  dividends  and  distributions  paid by the
ProFund.

     Average annual total return quotations for periods of two or more years are
computed by finding the average annual compounded rate of return over the period
that would equal the initial amount invested to the ending redeemable value.

     The aggregate  return for each ProFund for the one year and since inception
periods ended December 31, 1998, were as follows:

     This  performance data represents past performance and is not an indication
of future results. The UltraEurope ProFund and UltraShort Europe ProFund had not
commenced operations as of December 31, 1998.

YIELD CALCULATIONS

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

     Since yield fluctuates, yield data cannot necessarily be used to compare an
investment  in the Money Market  ProFund's  shares with bank  deposits,  savings
accounts,  and similar investment  alternatives which often provide an agreed or
guaranteed  fixed yield for a stated period of time.  Shareholders  of the Money
Market  ProFund should  remember that yield  generally is a function of the kind
and quality of the instrument held in portfolio,  portfolio maturity,  operating

     For the seven-day  period ended December 31, 1998, the seven-day  effective
yield for the Investor Shares and Service Shares of the Money Market ProFund was
4.86% and 3.84%, respectively.

COMPARISONS OF INVESTMENT PERFORMANCE

     In conjunction with performance  reports,  promotional  literature,  and/or
analyses of shareholder  service for a ProFund,  comparisons of the  performance
information of the ProFund for a given period to the  performance of recognized,
unmanaged indexes for the same period may be made. Such indexes include, but are
not  limited  to,  ones  provided  by Dow  Jones &  Company,  Standard  & Poor's
Corporation,  Lipper Analytical  Services,  Inc., Shearson Lehman Brothers,  the
National  Association of Securities  Dealers,  Inc., The Frank Russell  Company,
Value Line  Investment  Survey,  the American Stock Exchange,  the  Philadelphia
Stock Exchange, Morgan Stanley Capital International,  Wilshire Associates,  the
Financial  Times-Stock  Exchange,  and the Nikkei  Stock  Average  and  Deutcher
Aktienindex,  all of which are unmanaged market indicators. Such comparisons can
be a useful  measure of the quality of a ProFund's  investment  performance.  In
particular, performance information for the Bull ProFund, the UltraBull ProFund,
the Bear ProFund and the UltraBear  ProFund may be compared to various unmanaged
indexes,  including,  but not  limited  to,  the S&P 500  Index or the Dow Jones
Industrial  Average;  performance  information  for the UltraOTC  ProFund may be
compared to various unmanaged indexes, including, but not limited to its current
benchmark, the NASDAQ 100 Index.

     In addition,  rankings,  ratings, and comparisons of investment performance
and/or   assessments  of  the  quality  of  shareholder   service  appearing  in
publications such as Money,  Forbes,  Kiplinger's  Magazine,  Personal Investor,
Morningstar,  Inc., and similar sources which utilize  information  compiled (i)
internally,  (ii) by Lipper Analytical Services,  Inc.  ("Lipper"),  or (iii) by
other recognized analytical services, may be used in sales literature. The total
return  of each  ProFund  (other  than the  Money  Market  ProFund)  also may be
compared to the  performances  of broad groups of  comparable  mutual funds with
similar  investment  goals, as such performance is tracked and published by such
independent organizations as Lipper and CDA Investment Technologies, Inc., among
others. The Lipper ranking and comparison,  which may be used by the ProFunds in
performance  reports,  will be drawn from the  "Capital  Appreciation  ProFunds"
grouping for the Bull ProFund,  the UltraBull ProFund,  the Bear ProFund and the
UltraBear ProFund and from the "Small Company Growth ProFunds"  grouping for the
UltraOTC ProFund. In addition,  the broad-based Lipper groupings may be used for
comparison to any of the ProFunds.

     Further information about the performance of the ProFunds will be contained
in the ProFunds' annual reports to  shareholders,  which may be obtained without
charge by writing to the ProFunds at the address or telephoning  the ProFunds at
the telephone number set forth on the cover page of this SAI.

RATING SERVICES

     The  ratings of  Moody's  Investors  Service,  Inc.  and  Standard & Poor's
Ratings Group  represent their opinions as to the quality of the securities that
they  undertake  to rate.  It should be  emphasized,  however,  that ratings are
relative  and  subjective  and are not absolute  standards of quality.  Although
these ratings are an initial  criterion for selection of portfolio  investments,
Bankers  Trust also makes its own  evaluation  of these  securities,  subject to
review by the Board of Trustees.  After purchase by the Portfolio, an obligation
may cease to be rated or its rating may be reduced  below the  minimum  required
for purchase by the  Portfolio.  Neither  event would  require the  Portfolio to
eliminate the  obligation  from its  portfolio,  but Bankers Trust will consider
such an event in its  determination  of whether the Portfolio should continue to
hold the  obligation.  A  description  of the  ratings  used  herein  and in the
Prospectus is set forth in the Appendix to this SAI.

                                    APPENDIX

                        DESCRIPTION OF SECURITIES RATINGS

DESCRIPTION OF S&P'S CORPORATE RATINGS:

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

     AA-Bonds  rated AA have a very strong  capacity to pay  interest  and repay
principal and differ from the highest rated issuers only in small degree.

     S&P's  letter  ratings may be modified by the addition of a plus or a minus
sign,  which is used to show  relative  standing  within  the major  categories,
except in the AAA rating category.

DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS:

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

     Aa-Bonds  which  are  rated  Aa are  judged  to be of high  quality  by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds.  They are rated lower than the best bonds  because  margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements  may be of greater  amplitude  or there may be other  elements  present
which make the long-term risks appear somewhat larger than in Aaa securities.

     Moody's  applies the numerical  modifiers 1, 2 and 3 to each generic rating
classification  from Aa through B. The  modifier 1 indicates  that the  security
ranks in the higher end of its  generic  category;  the  modifier 2  indicates a
mid-range  ranking;  and the  modifier 3  indicates  that the issue ranks in the
lower end of its generic rating category.

DESCRIPTION OF FITCH INVESTORS SERVICE'S CORPORATE BOND RATINGS:

     AAA-Securities of this rating are regarded as strictly high-grade,  broadly
marketable,  suitable for investment by trustees and fiduciary institutions, and
liable to slight  market  fluctuation  other than  through  changes in the money
rate.  The  factor  last  named is of  importance  varying  with the  length  of
maturity. Such securities are mainly senior issues of strong companies,  and are
most numerous in the railway and public utility  fields,  though some industrial
obligations  have this rating.  The prime feature of an AAA rating is showing of
earnings several times or many times interest  requirements  with such stability
of  applicable  earnings  that  safety is beyond  reasonable  question  whatever
changes occur in conditions.  Other features may enter in, such as a wide margin
of protection through collateral security or direct lien on specific property as
in the  case of high  class  equipment  certificates  or bonds  that  are  first
mortgages on valuable real estate.  Sinking funds or voluntary  reduction of the
debt by call or purchase are often  factors,  while  guarantee or  assumption by
parties other than the original debtor may also influence the rating.

     AA-Securities in this group are of safety virtually beyond question, and as
a class are readily  salable while many are highly active.  Their merits are not
greatly unlike those of the AAA class,  but a security so rated may be of junior
though  strong  lien in many cases  directly  following  an AAA  security or the
margin of safety is less strikingly  broad. The issue may be the obligation of a
small  company,  strongly  secure but  influenced  as the  ratings by the lesser
financial power of the enterprise and more local type of market.




<PAGE>


DESCRIPTION OF DUFF & PHELPS' CORPORATE BOND RATINGS:

     AAA-Highest  credit quality.  The risk factors are  negligible,  being only
slightly more than for risk-free U.S. Treasury Funds.

     AA+, AA-High credit quality.  Protection factors are strong. Risk is modest
but may vary slightly from time to time because of economic conditions.

DESCRIPTION OF S&P'S MUNICIPAL BOND RATINGS:

     AAA-Prime-These  are  obligations  of the  highest  quality.  They have the
strongest capacity for timely payment of debt service.

     General  Obligation  Bonds-In a period of economic stress, the issuers will
suffer  the  smallest  declines  in  income  and  will be least  susceptible  to
autonomous decline.  Debt burden is moderate. A strong revenue structure appears
more  than  adequate  to  meet  future  expenditure  requirements.   Quality  of
management appears superior.

     Revenue  Bonds-Debt  service  coverage has been, and is expected to remain,
substantial;  stability of the pledged revenues is also exceptionally strong due
to the competitive  position of the municipal enterprise or to the nature of the
revenues. Basic security provisions (including rate covenant,  earnings test for
issuance  of  additional  bonds  and  debt  service  reserve  requirements)  are
rigorous. There is evidence of superior management.

     AA-High  Grade-The  investment  characteristics  of bonds in this group are
only slightly less marked than those of the prime quality issues. Bonds rated AA
have the second strongest capacity for payment of debt service.

     S&P's  letter  ratings may be modified by the addition of a plus or a minus
sign,  which  is  used  to  show  relative  standing  within  the  major  rating
categories, except in the AAA rating category.

DESCRIPTION OF MOODY'S MUNICIPAL BOND RATINGS:

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

     Aa-Bonds  which are rated Aa judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high grade
bonds.  They are rated lower than the best bonds  because  margins of protection
may not be as large as in Aaa securities,  or fluctuation of protective elements
may be of greater  amplitude,  or there may be other elements present which make
the long-term risks appear somewhat larger than in Aaa securities.

     Moody's  may  apply  the   numerical   modifier  in  each  generic   rating
classification  from Aa through B. The  modifier 1 indicates  that the  security
within its generic  rating  classification  possesses the  strongest  investment
attributes.

DESCRIPTION OF S&P'S MUNICIPAL NOTE RATINGS:

     Municipal  notes with  maturities  of three years or less are usually given
note ratings  (designated  SP-1 or SP-2) to distinguish  more clearly the credit
quality of notes as  compared  to bonds.  Notes rated SP-1 have a very strong or
strong  capacity to pay  principal  and  interest.  Those issues  determined  to
possess overwhelming safety  characteristics are given the designation of SP-1+.
Notes rated SP-2 have a satisfactory capacity to pay principal and interest.



<PAGE>


DESCRIPTION OF MOODY'S MUNICIPAL NOTE RATINGS:

     Moody's  ratings for state and municipal notes and other  short-term  loans
are  designated  Moody's  Investment  Grade (MIG) and for  variable  rate demand
obligations  are  designated  Variable  Moody's  Investment  Grade (VMIG).  This
distinction  recognizes  the  differences  between  short-term  credit  risk and
long-term  risk.  Loans  bearing the  designation  MIG-1/VMIG-1  are of the best
quality,  enjoying strong  protection from  established  cash flows of funds for
their servicing or from  established  and  broad-based  access to the market for
refinancing,  or both.  Loans the designation  MIG-2/VMIG-2 are of high quality,
with ample margins of protection, although not as large as the preceding group.

DESCRIPTION OF S&P COMMERCIAL PAPER RATINGS:

     Commercial  paper  rated  A-1 by S&P  indicates  that the  degree of safety
regarding  timely payment is either  overwhelming  or very strong.  Those issues
determined to posses overwhelming safety characteristics are denoted A-1+.

DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS:

     The rating  Prime-1 is the  highest  commercial  paper  rating  assigned by
Moody's.   Issuers  rated  Prime-1  (or  related  supporting  institutions)  are
considered to have a superior  capacity for  repayment of short-term  promissory
obligations.

DESCRIPTION OF FITCH INVESTORS SERVICE'S COMMERCIAL PAPER RATINGS:

     F-1+-Exceptionally  Strong Credit Quality.  Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.

     F-1-Very  Strong Credit  Quality.  Issues  assigned this rating  reflect an
assurance of timely  payment  only  slightly  less in degree than the  strongest
issue.

DESCRIPTION OF DUFF & PHELPS' COMMERCIAL PAPER RATINGS:

     Duff  1+-Highest  certainly  of  timely  payment.   Short  term  liquidity,
including  internal  operating  factors and/or access to alternative  sources of
funds,  is outstanding,  and safety is just below risk free U.S.  Treasury short
term obligations.

     Duff 1-Very high certainty of timely +.

DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS:

     The rating  Prime-1 is the  highest  commercial  paper  rating  assigned by
Moody's.  Issuers  rated  Prime-1  (or  relating  supporting  institutions)  are
considered to have a superior  capacity for  repayment of short-term  promissory
obligations.

DESCRIPTION OF FITCH INVESTORS SERVICE'S COMMERCIAL PAPER RATINGS:

     F-1+-Exceptionally  Strong Credit Quality.  Issues assigned this rating are
regarded as having the strongest  degree of assurance  for timely  payment risk.
Capacity for timely repayment of principal and interest is substantial.  Adverse
changes in business  economic or financial  conditions  may increase  investment
risk albeit not very significantly.

     A-Obligations  for which there is a low  expectation  of  investment  risk.
Capacity  for timely  repayment of  principal  and interest is strong,  although
adverse  changes in  business,  economic  or  financial  conditions  may lead to
increased investment risk.
<PAGE>

     BBB-Capacity  for timely  repayment of principal  and interest is adequate,
although adverse changes in business,  economic or financial conditions are more
likely  to lead to  increased  investment  risk than for  obligations  in higher
categories.

     BB-Obligations  for  which  there  is  a  possibility  of  investment  risk
developing.  Capacity for timely repayment of principal and interest exists, but
is susceptible  over time to adverse changes in business,  economic or financial
conditions.

     B-Obligations  for  which  investment  risk  exists.  Timely  repayment  of
principal and interest is not sufficiently  protected against adverse changes in
business, economic or financial conditions.

     CCC-Obligations  for which  there is a  current  perceived  possibility  of
default.  Timely  repayment of principal  and interest is dependent on favorable
business, economic or financial conditions.

     CC-Obligations  which are highly  speculative  or which have a high risk of
default.

     C-Obligations which are currently in default.

     Notes: "+" or "-".

DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS:

     The rating  Prime-1 is the  highest  commercial  paper  rating  assigned by
Moody's.   Issuers  rated  Prime-1  (or  related  supporting  institutions)  are
considered to have a superior  capacity for  repayment of short-term  promissory
obligations.

DESCRIPTION OF FITCH INVESTORS SERVICE'S COMMERCIAL PAPER RATINGS:

     F-1+-Exceptionally  Strong Credit Quality.  Issues assigned this rating are
regarded  as having the  strongest  degree of  assurance  for  timely  business,
economic or financial conditions.

     A3-Obligations supported by an adequate capacity for timely repayment. Such
capacity  is more  susceptible  to adverse  changes  in  business,  economic  or
financial conditions than for obligations in higher categories.

     B-Obligations for which the capacity for timely repayment is susceptible to
adverse changes in business, economic or financial conditions.

     C-Obligations  for which there is an  inadequate  capacity to ensure timely
repayment.

     D-Obligations  which have a high risk of default or which are  currently in
default.

DESCRIPTION OF THOMSON BANK WATCH SHORT-TERM RATINGS:

     TBW-1-The highest category; indicates a very high likelihood that principal
and interest will be paid on a timely basis.

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

     TWB-3-The  lowest  investment-grade  category;  indicates  that  while  the
obligation  is more  susceptible  to adverse  developments  (both  internal  and
external) than those with higher ratings,  the capacity to service principal and
interest in a timely fashion is considered adequate.

     TWB-4-The lowest rating category; this rating is regarded as non-investment
grade and therefore speculative.



<PAGE>


DESCRIPTION OF THOMSON BANKWATCH LONG-TERM RATINGS:

     AAA-The highest category; indicates that the ability to repay principal and
interest on a timely basis is extremely high.

     AA-The second -highest  category;  indicates a very strong ability to repay
principal and interest on a timely basis, with limited incremental risk compared
to issues rated in the highs category.

     A-The third-highest category;  indicates the ability to repay principal and
interest  is  strong.  Issues  rated "A"  could be more  vulnerable  to  adverse
developments (both internal and external) than obligations with higher ratings.

     BBB-The lowest investment-grade category;  indicates an acceptable capacity
to  repay  principal  and  interest.  Issues  rated  "BBB"  are,  however,  more
vulnerable to adverse developments (both internal and external) than obligations
with higher ratings.

NON-INVESTMENT  GRADE (ISSUES REGARDED AS HAVING SPECULATIVE  CHARACTERISTICS IN
THE LIKELIHOOD OF TIMELY REPAYMENT OF PRINCIPAL AND INTEREST.)

     BB-While not investment grade, the "BB" rating suggests that the likelihood
of default is considerably less than for lower-rated issues.  However, there are
significant  uncertainties  that could affect the ability to adequately  service
debt obligations.

     B-Issues  rated  "B" show a higher  degree  of  uncertainty  and  therefore
greater  likelihood of default than  higher-rated  issues.  Adverse  development
could well  negatively  affect the payment of interest and principal on a timely
basis.

     CCC-Issues  rate "CCC"  clearly  have a high  likelihood  of default,  with
little capacity to address further adverse changes in financial circumstances.

     CC-"CC" is  applied to issues  that are  subordinate  to other  obligations
rated "CCC" and are  afforded  less  protection  in the event of  bankruptcy  or
reorganization.

     D-Default

     These long-term debt ratings can also be applied to local currency debt. In
such cases the ratings defined above will be preceded by the designation  "local
currency".


A RATING IN THE LONG-TERM  DEBT  CATEGORIES  MAY INCLUDE A PLUS (+) OR MINUS (-)
DESIGNATION,  WHICH INDICATES WHERE WITHIN THE RESPECTIVE  CATEGORY THE ISSUE IS
PLACED.
