         This  prospectus  describes the UltraEuro  ProFund and UltraShort  Euro
ProFund (the "ProFunds").  UltraEuro ProFund seeks daily investment results that
corresponds  to twice  (200%)  the  performance  of the  ProFunds  Europe  Index
("PEI"). UltraShort Euro ProFund seeks daily investment results that corresponds
to twice (200%) the inverse  (opposite) of the  performance  of the PEI. The PEI
was  created by  ProFund  Advisors  LLC (the  "Advisor"),  ProFunds'  investment
advisor.  The PEI is equal to the average of the performance  (determined once a
day as of one-half hour after the opening of the  referenced  exchange) of three
large  capitalization   European  equity  indices:   Great  Britain's  FTSE-100,
Germany's  Deutsche  Aktienindex  ("DAX"),  and France's CAC-40.  Sales are made
without any sales charge at net asset value.

         The ProFunds involve special risks, some not  traditionally  associated
with mutual funds.  Unlike that of most equity mutual funds, the value of shares
of  UltraShort  Euro ProFund  should  normally fall when the prices of shares of
companies  within its market  segment  rise. In addition,  the  ProFunds'  risks
include  those  related  to  the  use of  aggressive  and  leveraged  investment
techniques,  high  portfolio  turnover and possible  tracking  error.  Investors
should carefully review and evaluate these risks in considering an investment in
the ProFunds to determine  whether an investment in the ProFunds is appropriate.
The  ProFunds  alone do not  constitute a balanced  investment  plan and are not
intended  for  investors  whose   principal   objective  is  current  income  or
preservation  of capital.  See  "Special  Risk  Considerations."  Because of the
inherent risks in any  investment,  there can be no assurance that the ProFunds'
investment objectives will be achieved.

         This prospectus  relates only to UltraEuro  ProFund and UltraShort Euro
ProFund.  Interested persons who wish to obtain a copy of the prospectus for the
Bull ProFund,  UltraBull  ProFund,  Bear ProFund,  UltraBear  ProFund,  UltraOTC
ProFund, UltraShort OTC ProFund and Money Market ProFund may contact ProFunds at
the address above or by  telephoning  ProFunds at the telephone  numbers  listed
above. Investors should read this Prospectus and retain it for future reference.
This  Prospectus is designed to set forth  concisely the information an investor
should know about the  ProFund  before  investing.  A  Statement  of  Additional
Information ("SAI"), dated February __, 1999, as supplemented from time to time,
containing  additional  information  about the  ProFunds has been filed with the
Securities and Exchange  Commission and is incorporated  herein by reference.  A
copy of this SAI is available,  without charge,  upon request to ProFunds at the
address above or by telephoning ProFunds at the telephone numbers above.

THESE  SECURITIES  HAVE NOT BEEN APPROVED OR  DISAPPROVED  BY THE SECURITIES AND
EXCHANGE  COMMISSION NOR ANY STATE SECURITIES  COMMISSION NOR HAS THE SECURITIES
AND  EXCHANGE  COMMISSION  OR ANY STATE  SECURITIES  COMMISSION  PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

     charge may be waived at the discretion of ProFunds.
(2)  Based on estimated  expenses to be incurred in the ProFunds'  first year of
     operations.  Other  expenses  include fees of .15% for  administration  and
     shareholder  services.  The fee  under  the  Shareholder  Services  Plan is
     calculated on the basis of the average net assets of each ProFund's Service
     Shares at an annual rate not to exceed 1.00%.

Examples

         Assuming  hypothetical  investments  of $1,000 in  Investor  Shares and
Service  Shares,  a 5% annual  return,  and  redemption  at the end of each time
period, an investor in the ProFunds would pay operating expenses as follows:

                                             1 Year            3 Years
                  Investor Shares             $[14]             $[42]
                  Service Shares              $[24]             $[73]

         The  preceding  table  of fees  and  expenses  is  provided  to  assist
investors in  understanding  the various  costs and expenses  which may be borne
directly or indirectly by an investor.  The percentages shown above are based on
estimates.  The 5% assumed annual return is for comparison  purposes only. For a
more  complete  discussion  of the  fees  connected  with an  investment  in the
ProFunds and the  services  provided to the  ProFunds,  see  "Management  of the
ProFunds" in this  Prospectus and in the SAI. THE PRECEDING  EXAMPLES SHOULD NOT
BE CONSIDERED A REPRESENTATION  OF PAST OR FUTURE EXPENSES;  ACTUAL EXPENSES MAY
BE GREATER OR LESS THAN THOSE SHOWN.

                             SPECIAL CONSIDERATIONS

         The ProFunds present certain risks, some not typically  associated with
mutual funds.  Shareholders  should consider the special factors discussed below
that are associated with the investment  policies of the ProFunds in determining
the appropriateness of investing in the ProFunds.

Tracking Error

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

Aggressive Investment Techniques

         The ProFunds  may engage in certain  aggressive  investment  techniques
which may include engaging in short sales and transactions in futures  contracts
and  options on  securities,  securities  indexes,  and futures  contracts.  The
ProFunds  expect that they will  primarily  use these  techniques  in seeking to
achieve their investment  objectives and that a significant portion (up to 100%)
of the assets of each ProFund will be held in liquid instruments in a segregated
account by the ProFund as "cover" for these investment techniques.

         Participation  in the  options  or  futures  markets  by  the  ProFunds
involves distinct  investment risks and transaction costs. Risks inherent in the
use of options, futures contracts, and options on futures contracts include: (1)
adverse  changes in the value of such  instruments;  (2)  imperfect  correlation
between  the price of options  and futures  contracts  and  options  thereon and
movements  in  the  price  of  the  underlying  securities,  index,  or  futures
contracts;  (3) the fact that the  skills  needed to use  these  strategies  are
different from those needed to select portfolio securities; and (4) the possible
absence of a liquid secondary market for any particular  instrument at any time.
For further information regarding these investment  techniques,  see "Investment
Objectives and Policies."

Leverage

         The ProFunds 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 a ProFund 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 a ProFund's  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 the ProFunds  achieve
their investment  objectives,  during market  conditions  adverse to a ProFund's
objective,  shareholders  should  experience a loss of  approximately  twice the
amount they would have incurred had the ProFund not been leveraged.



<PAGE>


Portfolio Turnover

         The  ProFunds   anticipate  that  their   investors,   as  part  of  an
asset-allocation or market-timing  investment strategy, will frequently exchange
shares of a ProFund for shares in other ProFunds pursuant to the exchange policy
(see  "Shareholders'  Guide - How to Exchange Shares of ProFunds"),  which would
cause the ProFunds to experience  high portfolio  turnover.  A higher  portfolio
turnover rate would likely involve correspondingly greater brokerage commissions
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.  Pursuant to the formula prescribed
by the  Securities and Exchange  Commission  (the  "Commission"),  the portfolio
turnover  rate for a  ProFund  is  calculated  without  regard  to  instruments,
including  options  and  futures  contracts,  having a maturity of less than one
year.  The  ProFunds  typically  hold most of their  investments  in  short-term
options and futures  contracts  and other  instruments  which are  excluded  for
purposes of computing portfolio turnover.  Therefore,  based on the Commission's
portfolio  turnover formula,  each ProFund expects a portfolio  turnover rate of
approximately 0%.

Non-Diversified Status

         The  ProFunds  are   "non-diversified."  The  ProFunds  are  considered
"non-diversified"  because a relatively high percentage of each ProFund's assets
may be  invested in the  securities  of a limited  number of issuers,  primarily
within the same economic sector. Each 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. The ProFunds' classification as "non-diversified"  investment companies
means that the  proportion of the  ProFunds'  assets that may be invested in the
securities  of a single issuer is not limited by the  Investment  Company Act of
1940 (the "1940 Act").  The  ProFunds,  however,  intend to seek to qualify as a
"regulated  investment company" for purposes of the Internal Revenue Code, which
imposes  diversification  requirements on the ProFunds that are less restrictive
than the requirements applicable to "diversified" investment companies under the
1940 Act.

                       INVESTMENT OBJECTIVES AND POLICIES

         The ProFunds may be used by  professional  money managers and investors
as part of an asset-allocation or market-timing  investment strategy,  to create
investment exposure to a particular segment of the securities market or to hedge
an existing investment portfolio.

         The  investment  objective  of  the  UltraEuro  ProFund  is to  provide
investment  returns  that  correspond  to 200% of the daily  performance  of the
ProFunds Europe Index ("PEI").  The PEI was created by ProFund Advisors LLC (the
"Advisor"), ProFunds' investment advisor. The PEI is equal to the average of the
performance of three large capitalization European equity indices: the FTSE-100,
the  Deutsche  Aktienindex  ("DAX"),  and the CAC-40.  For these  purposes,  the
performance  of an index is  measured  by  comparing  its  level  one-half  hour
following  the opening of the  referenced  exchange with the index's level as of
the same time on the prior business day. The UltraEuro  ProFund seeks to achieve
this  correlation  on each business day.  Under its  investment  objective,  the
UltraEuro  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  Euro 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  Euro ProFund's  investment
objective is to provide investment results that will inversely correlate to 200%
of the performance of the PEI. The UltraShort Euro ProFund seeks to achieve this
inverse correlation on each business day.

         If the UltraShort Euro 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  Euro
ProFund would  decrease for that day  proportional  to twice any increase in the
level of the PEI for that day.



<PAGE>


         For  example,  if the PEI were to decrease by 1% on a  particular  day,
investors in the UltraShort  Euro 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  Euro  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  futures  contracts,
options on stock index futures  contracts,  and options on securities  and stock
indexes.

         Fundamental securities analysis is not generally used by the Advisor in
seeking to correlate with a ProFund's  benchmark.  Rather, the Advisor primarily
uses  statistical  and  quantitative  analysis to determine the  investments the
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 the  ProFund's  investment  results  to vary from a
perfect  correlation to its benchmark.  Each ProFund,  however,  does not expect
that  its  total  returns  will  vary  adversely  from  its  respective  current
benchmarks  by more than ten percent over the course of a year,  although  there
can  be  no   guarantee   with  respect  to  such   correlation.   See  "Special
Considerations."

         It is the policy of the 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.

         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
or 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 the 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.

         On  January  1,  1999,  the  European  Monetary  Union  (EMU)  plans 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.

are France Telecom (9.8%), AXA-UAP (6.9%), and L'Oreal (5.9%).

Futures Contracts and Related Options

         The  ProFunds 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 regulatory 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 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 during the option period.

         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  Commodities  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.

         Although the ProFunds  intend to buy or 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 Transactions

         The ProFunds may purchase and write  options on stock  indexes that are
traded on U.S. and foreign  exchanges and options traded  over-the-counter  with
broker-dealers, financial institutions or other parties. The ProFunds will enter
into option  transactions to create  investment  exposure  consistent with their
investment objectives or hedge or limit the exposure of their positions.

         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.
<PAGE>

         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. Use of
such options  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.

         Over-the-counter  options are  purchased  or written by the ProFunds in
privately  negotiated  transactions.  Such options are subject to the  ProFunds'
illiquid investment limitations. It may not be possible for a ProFund to dispose
of an option it has  purchased or terminate its  obligations  under an option it
has written at a time when the Advisor  believes it would be  advantageous to do
so. In addition, over-the-counter options involve the risk that the counterparty
participating is such transactions will not fulfill their obligation.

Swap Agreements

         The  ProFunds  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.



<PAGE>


Short Sales

         The  UltraShort  Euro  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.

U.S. Government Securities

         The ProFunds  may invest in U.S.  government  securities  in pursuit of
their  investment  objectives,  as "cover"  for the  investment  techniques  the
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.

        Some obligations  issued or guaranteed by agencies or  instrumentalities
of the U.S.  government  are  backed by the full  faith  and  credit of the U.S.
Treasury.  Such  agencies and  instrumentalities  may borrow funds from the U.S.
Treasury.  However,  no assurances  can be given that the U.S.  government  will
provide such financial  support to the obligations of the other U.S.  government
agencies  or  instrumentalities  in  which a  ProFund  invests,  since  the U.S.
government is not obligated to do so. These other agencies and instrumentalities
are   supported  by  either  the  issuer's   right  to  borrow,   under  certain
circumstances,  an amount  limited  to a specific  line of credit  from the U.S.
Treasury, the discretionary authority of the U.S. government to purchase certain
obligations  of an agency or  instrumentality,  or the  credit of the  agency or
instrumentality itself.

Repurchase Agreements

         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. A
ProFund  will enter into  repurchase  agreements  only with member  banks of the
Federal Reserve System or primary  dealers of U.S.  government  securities.  The
Advisor will monitor the  creditworthiness of each of the firms which is a party
to a repurchase agreement with any of the ProFunds. In the event of a default or
bankruptcy by the seller,  the ProFund will liquidate  those  securities  (whose
market value, including accrued interest,  must be at least equal to 100% of the
dollar amount invested by the ProFund in each  repurchase  agreement) held under
the applicable repurchase agreement,  which securities constitute collateral for
the seller's  obligation  to pay.  However,  liquidation  could involve costs or
delays and, to the extent proceeds from the sales of these  securities were less
than the  agreed-upon  repurchase  price,  the ProFund  would  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 to treat repurchase  agreements that do not mature within
seven  days (or which may not be  terminated  within  seven  calendar  days upon
notice by the ProFund) as illiquid for purposes of their investment policies.
<PAGE>

Cash Reserves

         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.

Transaction Expenses

         The  ProFunds   anticipate  that  their   investors,   as  part  of  an
asset-allocation or market-timing  investment strategy, will frequently exchange
their shares of a particular  ProFund for shares in other  ProFunds  pursuant to
the exchange  policy (see  "Shareholders'  Guide - How to Exchange Shares of the
ProFunds"),  which  would  cause  the  ProFunds  to  experience  high  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.

Other Investment Policies

         The ProFunds  also may engage in certain  other  investment  practices.
However,  none of the ProFunds  presently  intends to invest more than 5% of the
ProFund's  net  assets  in any of  these  practices.  Each of the  ProFunds  may
purchase  securities on a when-issued or  delayed-delivery  basis,  and also may
lend portfolio securities to brokers, dealers, and financial institutions.  Each
ProFund  may  borrow  money  for  investment  purposes  or  invest  in  illiquid
securities.  Each of the  ProFunds  also 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.

How to Invest in the ProFunds

         General

         The shares of each ProFund are offered at the net asset value per share
next  computed  after  receipt of the  investor's  order.  No sales  charges are
imposed  on  initial  or  subsequent  investments  in a  ProFund.  See  "General
Information About the Trust -- Determination of Net Asset Value".

         Minimum Investment

         The minimum  initial  investment in the ProFunds for investors who have
engaged a registered  investment adviser with  discretionary  authority over the
shareholder's   account  is   $5,000.   For  all  other   shareholder   accounts
("Self-Directed  Accounts"),  the minimum initial  investment in the ProFunds is
$15,000.  These  minimums  also  apply  to  retirement  plan  accounts  and  are
determined  based upon the total  investment in all ProFunds.  ProFunds,  at its
discretion,  may accept  lesser  amounts in certain  circumstances.  There is no
minimum amount for subsequent investments, other than those made pursuant to the
automatic  investment plan, in a ProFund.  ProFunds reserves the right to reject
or refuse,  at ProFunds'  discretion,  any order for the purchase of a ProFund's
shares in whole or in part.

How to Exchange Shares of the ProFunds

       Shares of a ProFund may be exchanged,  without any charge,  for shares of
the other ProFund or for shares of the Money Market  ProFund on the basis of the
respective  net asset values of the shares  involved.  Exchanges  may be made by
letter or by telephone at the address or numbers  indicated on the cover of this
Prospectus. Telephone requests for share exchanges may only be made between 8:00
AM and 5:30 PM.  Telephone  requests  for share  exchanges  will receive the net
asset value per share next  determined.  The net asset  value of share  exchange
requests  made by mail will be  computed  based  upon the  price of shares  next
computed  after the receipt of the request.  Due to  differences  regarding when
exchange requests may be made with respect to the various ProFunds and the times
as of which the net asset values of their shares are determined,  a considerable
amount of time may elapse between  receipt of a request for a share exchange and
the  time at  which  the  exchange  is  completed.  Exchanges  with  respect  to
Self-Directed  Accounts must be for at least $1,000 or 100% of the account value
for the  ProFund,  whichever  is less,  from  which the  transfer  is made.  See
"Shareholders'  Guide -- Special  Information  Regarding  Telephone Requests for
Redemptions and Exchanges."

         To  implement  an exchange,  shareholders  must  provide the  following
information:

          . Name and telephone number;
          . Account name and number;
          . Taxpayer identification number;
          . Number of or percentage of shares or dollar value of shares to be
             exchanged; 
          . The name of the ProFunds from which the exchange is to be made; and 
          . The name of the ProFunds to which the exchange is to
             be made.

         The privilege to initiate  exchange  transactions  by telephone will be
made available to ProFund shareholders automatically. Exchanges may only be made
between  identically  registered  accounts.  The exchange privilege is available
only in states  where the  exchange  legally  may be made and may be modified or
discontinued  at any time.  In  addition,  see  "Shareholders'  Guide -- Special
Information  Regarding  Written  and  Telephone  Requests  for  Redemptions  and
Exchanges" regarding instructions received by telephone.

How to Withdraw Money (Redeem Shares)

         General

         An  investor  can  withdraw  all or any  portion of his  investment  by
redeeming  ProFund shares at the next determined net asset value per share after
receipt of the order.  Withdrawals  may be made by letter or by telephone at the
address or numbers indicated on the cover of this Prospectus. Telephone requests
for share  redemptions  may only be made between 8:00 AM and 5:30 PM.  Telephone
requests for share  redemptions  will receive the net asset value per share next
determined.  The net asset value of share redemption  requests made by mail will
be computed  based upon the price of shares next  computed  after the receipt of
the request.

         The privilege to initiate redemption  transactions by telephone will be
made  available  to  ProFund   shareholders   automatically.   Redemptions  from
Self-Directed  Accounts must be for at least $1,000 or 100% of the account value
for the ProFund,  whichever is less, from which the transfer is made. Payment of
the  redemption  proceeds  will be made  within  seven days after the  ProFunds'
receipt of the request for redemption.  For  investments  that have been made by
check,  payment  on  withdrawal  requests  will be delayed  until the  ProFunds'
transfer  agent is  reasonably  satisfied  that the  purchase  payment  has been
collected by the ProFunds (which may require up to 15 business days).

         Wire of Withdrawals

         Shareholders may request payment by wire of withdrawal  proceeds from a
ProFund.  The ProFunds charge $15 for each wire transfer of redemption proceeds;
this charge may be waived at the discretion of the ProFunds.



<PAGE>


         Redemptions to Third Party or Other Address

         Telephone  redemptions  are sent only to the  address  of record of the
redeeming  investor or to bank accounts  specified by the redeeming  investor in
the account application.  If the investor desires payment of redemption proceeds
to a third party or to a location other than the investor's address of record or
a bank account  specified in the investor's  account  application,  this request
must be in  writing,  and the  investor's  signature  must  be  guaranteed  by a
commercial  bank,  a broker,  dealer,  municipal  securities  dealer,  municipal
securities  broker,  government  securities  dealer,  or  government  securities
broker,  a national  securities  exchange,  registered  securities  association,
clearing agency, or a savings  association.  (A notarized signature cannot serve
as a guarantee for this purpose.)

Special Information Regarding Telephone Requests for Redemption and Exchanges

         When acting on  telephone  instructions  believed  to be  genuine,  the
ProFunds will not be liable for any loss resulting  from a fraudulent  telephone
transaction  request,  and the investor will bear the risk of any such loss. The
ProFunds  will  employ  reasonable  procedures  to  confirm  that the  telephone
instructions  are genuine;  and if the  ProFunds do not employ such  procedures,
then the ProFunds may be liable for any losses due to unauthorized or fraudulent
instructions. The ProFunds follow specific procedures for transactions initiated
by  telephone,   including,  among  others,  requiring  some  form  of  personal
identification  prior  to  acting  upon  instructions   received  by  telephone,
providing  written  confirmation  not later  than 5  business  days  after  such
transaction and/or tape recording of telephone instructions.

         Investors also should be aware that telephone  redemptions or exchanges
may be difficult to implement in a timely manner during  periods of  significant
economic or market  changes.  If such conditions  occur,  redemption or exchange
orders can be made by mail.  Telephone redemption and exchange privileges may be
terminated or modified by the ProFunds at any time.

How to Make Automatic Investments, Exchanges and Withdrawals

         Investors  may also  purchase  and redeem  ProFund  shares by arranging
systematic monthly, bimonthly, quarterly or annual investments into the ProFunds
(the  "Automatic  Investment  Plan"),  and  redemptions  from the ProFunds  (the
"Automatic  Withdrawal  Plan").  The minimum  investment  amounts are $1,000 per
transfer and minimum  withdrawal  amounts are $500 per transfer.  These minimums
are waived for IRA  shareholders  70 1/2 or older.  Additionally,  investors may
exchange,  on a regular basis,  shares of the Money Market ProFund for shares of
other ProFunds through ProFunds'  Automatic Exchange Plan. For more information,
including  terms  and  conditions,  about  automatic  investment,  exchange  and
withdrawal features, please call the ProFunds at 888-PRO-FNDS.

Dividends and Distributions

         All income  dividends and capital gains  distributions  of each ProFund
automatically  will be reinvested in additional shares of the ProFund at the net
asset value calculated on the ex-dividend date, unless an investor has requested
otherwise in writing.  Dividends and  distributions  of a ProFund are taxable to
the shareholders of the ProFund,  as discussed below under "Taxes," whether such
dividends and  distributions  are reinvested in additional shares of the ProFund
or received in cash.  Statements of account will be sent to ProFund shareholders
at least quarterly.

         The ProFunds  intend to distribute  annually any net investment  income
and net  realized  capital  gains to  shareholders.  The  ProFunds may declare a
special  distribution  if they believe that such a distribution  would be in the
best interests of its shareholders.
<PAGE>

Tax-Sheltered Retirement Plans

         ProFunds sponsors IRAs which enable  individuals to establish their own
retirement program  (including spousal IRAs,  Rollover IRAs, Roth IRAs, SEP IRAs
and Simple IRAs).  Fund-sponsored  retirement plans are charged an annual $15.00
maintenance fee and receive tax reporting  services.  In addition,  investors in
the following retirement plans are eligible to invest in ProFunds:

         . Keogh Accounts -- Defined Contribution Plans (Profit-Sharing Plans)
         . Profit Sharing Plans
         . Money Purchase Plans
         . Pension Plans
         . Internal Revenue Code Section 403(b)(7) Plans

         All distributions for  Fund-sponsored  retirement plans must be made by
completing the  appropriate  distribution  form. Any additional  deposits to the
ProFunds must distinguish the type and year of the contribution.

         For more  information on ProFunds IRAs, or any other  retirement  plan,
please call the ProFunds at 888-PRO-FNDS.  Shareholders are advised to consult a
tax  adviser on  ProFunds  IRA  contribution  and  withdrawal  requirements  and
restrictions.

Miscellaneous

         Involuntary Redemptions of Small Accounts

         Because of the administrative  expense of handling small accounts,  the
ProFunds  reserve  the  right to redeem  involuntarily  an  investor's  account,
including  a  retirement  account,  which  falls  below the  applicable  minimum
investment in total value in the ProFunds due to redemptions.  In addition, both
a request for a partial redemption by an investor whose account balance is below
the minimum  investment  and a request for a partial  redemption  by an investor
that would  bring the  account  balance  below the  minimum  investment  will be
treated as a request by the investor for a complete  redemption of that account.
Investors  holding  shares in a  retirement  account  should  be aware  that any
redemption from a retirement  account may result in tax consequences  including,
but not limited to, a 10% penalty on the amount  withdrawn if the shareholder is
under the age of 59 1/2.  Shareholders  should  consult their tax advisors about
such tax  consequences.  The ProFunds  reserve the right to modify their minimum
investment  requirements and the  corresponding  amounts below which involuntary
redemptions may be effected.

         Suspension of Redemptions

         The  right of  redemption  may be  suspended,  or the  date of  payment
postponed:  (i) for any period during which the New York Stock Exchange ("NYSE")
or the Federal Reserve Bank of New York, as  appropriate,  is closed (other than
customary  weekend or holiday  closings) or trading on the NYSE, as appropriate,
is  restricted;  (ii) for any period  during which an  emergency  exists so that
disposal of a ProFund's  investments or the determination of its net asset value
is  not  reasonably  practicable;  or  (iii)  for  such  other  periods  as  the
Commission, by order, may permit for protection of the ProFunds' investors.

         "Undeliverable" or "Uncashed" Dividend Checks

         If you  elect  to  receive  distributions  in cash and  checks  (1) are
returned and marked as  "undeliverable"  or (2) remain  uncashed for six months,
your cash election will be changed  automatically  and your future  dividend and
capital gains  distributions will be reinvested in the applicable  ProFund(s) at
the per  share net  asset  value  determined  as of the date of  payment  of the
distribution.  In  addition,  any  undeliverable  checks or checks  that  remain
uncashed  for six  months  will  be  canceled  and  will  be  reinvested  in the
applicable ProFund(s) at the per share net asset value determined as of the date
of cancellation.

         Transaction Charges

         In addition to charges  described  elsewhere  in this  Prospectus,  the
ProFunds also may make a charge of $25 for checks  returned for  insufficient or
uncollectible funds.



<PAGE>


         No Certificates

         In the  interest  of economy  and  convenience,  physical  certificates
representing  a  ProFund's  shares are not  issued.  Shares of each  ProFund are
recorded on a register by _____.

                                      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
Internal  Revenue Code of 1986,  as amended.  A RIC  generally is not subject to
federal  income tax on income and gains  distributed  in a timely  manner to its
shareholders. The ProFunds intend to make timely distributions in order to avoid
tax liability.

         Dividends  out  of  net  ordinary  income  and   distributions  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 shareholders as long-term capital gain
regardless of the length of time a shareholder has held the ProFund shares,  and
the rate of tax will depend  upon the  ProFund's  holding  period for the assets
whose sale  produces the gain. 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.  Any
gains  or  losses  recognized  by  the  ProFunds  from  over-the-counter  option
transactions generally constitute short-term capital gains or losses.

         The amount of an income dividend or capital gains distribution declared
by a ProFund during  October,  November or December of a year to shareholders 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.

         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 distributions made by the ProFunds for the preceding
year.  Distributions  by ProFunds  generally  will be subject to state and local
taxes.

         Certain  shareholders  are  required  by law to certify  that their tax
identification  number is  correct  and that  they are not  subject  to  back-up
withholding. In the absence of this certification,  the ProFunds are required to
withhold taxes at the rate of 31% on dividends, capital gains distributions, and
redemption  proceeds.  Amounts  withheld may be credited against a shareholder's
federal income tax.

         The foregoing is a brief summary of federal income tax  consequences of
owning ProFund  shares.  For more  information  about  federal,  state and local
taxes, please see your tax adviser and the SAI.

                                   MANAGEMENT
                                 OF THE PROFUNDS

Investment Advisor

         ProFund Advisors LLC

         The ProFunds are provided  investment advice and management services by
ProFund  Advisors LLC, a Maryland  limited  liability  company  formed on May 8,
1997,  with offices at 7900  Wisconsin  Avenue,  Suite 300,  Bethesda,  Maryland
20814.  Louis M. Mayberg and Michael L. Sapir own a controlling  interest in the
Advisor.

         Under an  investment  advisory  agreement  between the ProFunds and the
Advisor,  dated October 28, 1997, as amended  ________,  1999, the ProFunds each
pay the Advisor a fee at an  annualized  rate,  based on the  average  daily net
assets for each respective ProFund, of 0.90%. The Advisor manages the investment
and the  reinvestment of the assets of each of the ProFunds,  in accordance with
the investment objectives, policies, and limitations of the ProFunds, subject to
the general  supervision  and  control of the  ProFunds'  Board of Trustees  and
officers.  The Advisor bears all costs  associated with providing these advisory
services  and the  expenses of the  ProFunds'  Trustees  and  officers,  who are
affiliated  persons  of the  Advisor.  The  Advisor,  from  its  own  resources,
including  profits from advisory fees received from the ProFunds,  also may make
payments to broker-dealers  and other financial  institutions for their expenses
in connection with the distribution of ProFund shares,  and otherwise  currently
pays all distribution costs for ProFund shares.

         As recently created  entities,  the ProFunds will be subject to all the
risks  incident to the creation of a new  business,  including  the absence of a
history of  operations.  Michael L.  Sapir,  the  Advisor's  chairman  and chief
executive officer, is the former senior vice president of Padco Advisors,  Inc.,
the  investment  adviser to the  Rydex(R)  Funds and was an  attorney in private
practice for over thirteen years  specializing in advising issuers of investment
products,  including mutual funds.  Louis M. Mayberg,  the Advisor's  president,
co-founded  an  investment  banking firm in 1986 and has been  responsible  for,
among other things, managing the investment "hedge" fund sponsored by that firm.
William E. Seale, Ph.D., the Advisor's and the ProFunds' portfolio director, has
over  twenty-six  years of  experience  with  respect to the  commodity  futures
markets, including serving for five years pursuant to a presidential appointment
as commissioner on the United States Commodities Futures Trading Commission. The
ProFunds'   Administrator,   ________,   provides  operations,   compliance  and
administrative services for investment companies.

Service Providers

         Administrator, Transfer Agent, Fund Accounting Agent and Custodian

         ________  acts  as  Administrator  to  the  ProFunds.   _____  provides
administrative services necessary for the operation of the ProFunds,  including,
among other things, (i) preparation of shareholder  reports and  communications,
(ii) regulatory  compliance,  such as reports to and filings with the Commission
and state securities commissions, and (iii) general supervision of the operation
of the  ProFunds,  including  coordination  of  the  services  performed  by the
ProFunds'  Advisor,  custodians,  independent  accountants,  legal  counsel  and
others.  In addition,  _____ furnishes office space and facilities  required for
conducting  the  business  of the  ProFunds  and  pays the  compensation  of the
ProFunds' officers and employees affiliated with _____.

         For its  services as  Administrator,  each ProFund pays _____ an annual
fee  ranging  from  0.15% of average  daily net assets of $0 to $300  million to
0.05% of  average  daily net assets of $1 billion  and over.  _________  acts as
transfer agent and fund accounting agent for the ProFunds, for which it receives
additional   fees.   The   address  of   ___________   and   ______________   is
____________________________.

         ProFunds  Advisors  LLC,  pursuant  to a separate  Management  Services
Agreement,  performs  certain client support  services and other  administrative
services on behalf of the ProFunds. For these services, each ProFund will pay to
ProFund  Advisors LLC a fee at the annual rate of 0.15% of its average daily net
assets.

         UMB Bank,  N.A. acts as custodian to the  ProFunds;  its address is 928
Grand Avenue, Kansas City, Missouri.
<PAGE>

         Distributor

         ___________________________ will serve as the distributor and principal
underwriter    in   all   fifty   states   and   the   District   of   Columbia.
_____________________________  receives no  compensation  from the  ProFunds for
serving   as   distributor.    _______________________________'s    address   is
____________________________.

         Shareholder Services Plan -- Service Shares

         Each ProFund has adopted a  Shareholder  Services Plan (the "Plan") and
related agreement  ("Shareholder  Services  Agreement").  The Plan provides that
each ProFund will make payments to Authorized Firms (defined below) in an amount
up to 1.00% (on an annual basis) of the average daily value of the net assets of
such ProFund's Service class of shares attributable to or held in the name of an
Authorized Firm for its clients.  The Plan provides that the fee will be paid to
registered  investment  advisers,  banks,  trust  companies and other  financial
organizations  ("Authorized  Firms"),  for providing account  administration and
other services to their clients who are beneficial owners of such shares.

         The services provided by the Authorized Firms may include,  among other
things,  receiving,  aggregating and processing  shareholder or beneficial owner
(collectively   "shareholder")  orders;  furnishing  shareholder  subaccounting;
providing and maintaining  retirement plan records;  communicating  periodically
with  shareholders;  acting as the sole  shareholder  of record and  nominee for
shareholders;  maintaining account records for shareholders; answering questions
and handling  correspondence  from  shareholders  about their accounts;  issuing
various  shareholder reports and confirmations for transactions by shareholders;
performing daily investment  ("sweep")  functions for shareholders;  and account
administration  services.  ProFunds expects that the level of services  provided
with respect to these  accounts will be more  extensive  than  typically  occurs
under shareholder servicing plans.

         Holders  of Service  Shares of a ProFund  will bear all fees paid under
the Plan with  respect to such  shares as well as any other  expenses  which are
directly attributable to such shares.

         Authorized  Firms may charge  other fees to their  clients  who are the
beneficial  owners of Service Shares in connection  with their client  accounts.
These fees would be in addition to any amounts  received by the Authorized Firms
and would be for  services  other  than  those  provided  under the  Shareholder
Service  Agreement.  Under  the  terms  of the  Shareholder  Service  Agreement,
Authorized  Firms are required to provide  their clients with a schedule of fees
charged to such clients which relate to the  investment of customers'  assets in
Service Shares.

         Each ProFund will accrue payments made pursuant to the Plan daily.  The
payments  under the Plan  which are  required  to be  accrued  to the  ProFunds'
Service Shares on any day will not exceed the distributable income to be accrued
to such  shares on that day.  All  inquiries  by a  beneficial  owner of Service
Shares must be directed to such owner's Authorized Firm.

Year 2000

         Like other  funds and  business  organizations  around  the world,  the
ProFunds could be adversely affected if the computer systems used by the Advisor
and the ProFunds' other service  providers do not properly process and calculate
date-related  information for the Year 2000 and beyond.  In addition,  Year 2000
issues may adversely  affect  companies in which the ProFunds invest where,  for
example,  such companies incur  substantial costs to address Year 2000 issues or
suffer losses caused by the failure to adequately or timely do so.

         The ProFunds have been assured that the Advisor and the ProFunds' other
service  providers  have  developed  and are  implementing  clearly  defined and
documented  plans  intended  to  minimize  risks  to  services  critical  to the
ProFunds' operations associated with Year 2000 issues.  Internal efforts include
a commitment to dedicate  adequate staff and funding to identify and remedy Year
2000  issues,  and  specific  actions  such as  inventorying  software  systems,
determining  inventory  items that may not function  properly after December 31,
1999,  reprogramming  or replacing  such  systems,  and  retesting for Year 2000
readiness.  The Advisor and service  providers are likewise  seeking  assurances
from their  respective  vendors and suppliers  that such entities are addressing
any Year 2000 issues, and each provider intends to engage, where appropriate, in
private and industry or "streetwide"  interface testing of systems for Year 2000
readiness.
<PAGE>

         In the event that any systems upon which the ProFunds are dependent are
not Year 2000 ready by  December  31,  1999,  administrative  errors and account
maintenance   failures   would  likely  occur.   While  the  ultimate  costs  or
consequences  of  incomplete  or untimely  resolution of Year 2000 issues by the
Advisor or the ProFunds' service providers cannot be accurately assessed at this
time, the ProFunds  currently have no reason to believe that the Year 2000 plans
of the Advisor and the  ProFunds'  service  providers  will not be  completed by
December  31,  1999,  or  that  the  anticipated   costs  associated  with  full
implementation  of their  plans  will have a material  adverse  impact on either
their business operations or financial conditions of those of the ProFunds.  The
ProFunds and the Advisor will continue to closely monitor developments  relating
to this issue,  including  development by the Advisor and the ProFunds'  service
providers of contingency  plans for providing  back-up computer  services in the
event of a systems failure or the inability of any provider to achieve Year 2000
readiness.  Separately,  the Advisor  will  monitor  potential  investment  risk
related to Year 2000 issues.

Costs and Expenses

         The  ProFunds  bear all expenses of their  operations  other than those
assumed by the Advisor or _____.  Expenses of the ProFunds include,  but are not
limited to: the advisory fee;  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 fees 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 independent  Trustee's fees and expenses. In order to
increase  the return to  investors,  the  Advisor may from time to time agree to
voluntarily  waive or  reduce  its  fees,  while  retaining  its  ability  to be
reimbursed for such fees prior to the end of each fiscal year.

Portfolio Trading Practices

         The Advisor  determines  which securities to purchase and sell for each
non-money   market   ProFund,   selects   brokers  and  dealers  to  effect  the
transactions, and negotiates commissions. The Advisor expects that the non-money
market  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.  In placing orders for portfolio transactions,  the Advisor's policy
is to obtain the most  favorable  combination  of price and efficient  execution
available. Brokerage commissions are normally paid on exchange-traded securities
transactions and on options and futures transactions, as well as on common stock
transactions.  In order to obtain the brokerage and research services  described
below,  a  commission  may  sometimes  be paid  that is higher  than the  lowest
commission  available.  The ability to receive research services may be a factor
in the selection of one dealer acting as a principal over another.

         When selecting  broker-dealers to execute portfolio  transactions,  the
Advisor considers many factors,  including the rate of commission or size of the
broker-dealer's  "spread," the size and  difficulty of the order,  the nature of
the market for the security,  the willingness of the  broker-dealer to position,
the  reliability,   financial  condition,   general  execution  and  operational
capabilities of the  broker-dealer,  and the research,  statistical and economic
data furnished by the  broker-dealer  to the Advisor.  The Advisor may use these
services  in  connection  with  all  of  the  Advisor's  investment  activities,
including other investment accounts the Advisor advises. Conversely,  brokers or
dealers which supply research may be selected for execution of transactions  for
such other  accounts,  while the data may be used by the  Advisor  in  providing
investment advisory services to the ProFunds.


                               GENERAL INFORMATION
                                 ABOUT THE TRUST

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 nine 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 ProFunds 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  writ-ten  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  out 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
the ProFunds  itself would not be able to meet the Trust's  obligations and this
risk, thus, should be considered remote.

Determination of Net Asset Value

       The net asset values of the shares of the ProFunds are  determined  as of
one-half hour  following the opening of the last of the three  exchanges to open
(ordinarily,  4:30 AM Eastern Time) on each day the NYSE, London Stock Exchange,
Frankfurt  Stock  Exchange  and  Paris  Stock  Exchange  are open for  business.
Currently,  the NYSE is closed on weekends,  and the following  holiday closings
have been scheduled for 1999:  (i) New Year's Day,  Martin Luther King, Jr. Day,
Presidents'  Day,  Good  Friday,  Memorial  Day,  Independence  Day,  Labor Day,
Thanksgiving  Day and Christmas  Day; and (ii) the preceding  Friday when any of
those holidays  falls on a Saturday or the  subsequent  Monday when any of these
holidays falls on a Sunday. The London Stock Exchange,  Frankfurt Stock Exchange
or Paris Stock  Exchange is closed on the following  days:  New Year's Day, Good
Friday,  Easter Monday,  Labor Day (May 1), Early May Bank Holiday,  VE Day (May
8), Ascension,  Pentecost, August Bank Holiday, German Unity Day, Armistice Day,
Christmas Day, and the next business day after Christmas Day. 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 NYSE may modify its holiday schedule
at any time.

         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,  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  securities  in the  portfolio  of a 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 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 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.

         Futures  contracts  are valued at their last sale price as of  one-half
hour after the opening of the exchange on which the  underlying  securities  are
traded.  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 a ProFund  are valued at their last sale
price as of  one-half  hour  after  the  opening  of the  exchange  on which the
underlying securities are traded.

Fundamental Policies

         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  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
share-holders  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.

Trustees and Officers

         The  ProFunds  has a Board of  Trustees  which is  responsible  for the
general  supervision of ProFunds'  business.  The  day-to-day  operations of the
ProFunds are the responsibility of the ProFunds' officers.

Auditors

         PricewaterhouseCoopers  LLP are  the  auditors  of and the  independent
accountants for ProFunds.

         NO PERSON HAS BEEN  AUTHORIZED TO GIVE ANY  INFORMATION  OR TO MAKE ANY
REPRESENTATIONS  NOT  CONTAINED  IN  THIS  PROSPECTUS,  OR IN THE  STATEMENT  OF
ADDITIONAL INFORMATION  INCORPORATED HEREIN BY REFERENCE, IN CONNECTION WITH THE

                       STATEMENT OF ADDITIONAL INFORMATION

                        7900 Wisconsin Avenue, Suite 300
                            Bethesda, Maryland 20814
              (888) 776-5717 (Registered Investment Advisers Only)
                         (888) PRO-FNDS (For All Others)

   
     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 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 and are 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  April  24,  1998,  as
supplemented  and, with respect to the UltraEuro ProFund and the UltraShort Euro
ProFund,  February ___, 1999,  which  incorporates  this Statement of Additional
Information  by  reference.  A copy of each  Prospectus  is  available,  without
charge,  upon request at the address  above or by  telephoning  at the telephone
numbers above.

                                    PROFUNDS
   
     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 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'  Guide -- "How to Exchange Shares of
the ProFunds" in the Prospectuses).

                       INVESTMENT POLICIES AND TECHNIQUES

GENERAL

     Reference  is made to the sections  entitled  "Investment  Objectives"  and
"Investment  Policies  and  Techniques"  in  the  ProFunds'  Prospectuses  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
Prospectuses.  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 strategies of the ProFunds discussed below, and as discussed
in the Prospectuses, 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.
    
FUTURES CONTRACTS

     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.
<PAGE>

     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.

INDEX OPTIONS
   
     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 or to hedge or limit the exposure of their
positions.  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,  except for the UltraEuro  ProFund and the
UltraShort Euro ProFund,  may buy and write (sell) options on securities for the
purpose of realizing their respective ProFund's investment objective. 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 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
    
<PAGE>

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.
   
SWAP AGREEMENTS

     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 or 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),  in which event the secondary market on
that  exchange  (or in the  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.   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.  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. 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.

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.
<PAGE>

     As  required  by 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% 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. A lending ProFund/Portfolio may pay reasonable finders, borrowers,
administrative, and custodial Trustees in connection with a loan.

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.  A  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  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 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  invests in, and, thus, is a shareholder  of, another
investment  company,  the  ProFund's   shareholders  will  indirectly  bear  the
ProFund'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  bears  directly in  connection  with the
ProFund's own operations.

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.

     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.
<PAGE>

BANK OBLIGATIONS (MONEY MARKET PROFUND AND THE PORTFOLIO)

     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  concerning the types of securities and other instruments in
which the Portfolio may invest.

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

     The commercial  paper and other debt obligations in which the Portfolio may
invest are short-term,  unsecured negotiable promissory notes of U.S. or foreign
corporations that at the time of purchase meet the rating criteria  described in
the Prospectus.  Investments in foreign commercial paper generally involve risks
similar to those  described  above  relating to  obligations of foreign banks or
foreign branches of U.S. banks.

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.  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, the UltraBear
ProFund,  the UltraEuro  ProFund and the UltraShort Euro 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%.

                             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.
<PAGE>

     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.

     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.
<PAGE>

     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.

     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 foreign
         and U.S.  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.
<PAGE>

     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.

     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 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;

     (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;


<PAGE>



     (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)invest more than 5% of the Portfolio's  (ProFund's)  total assets in
          securities issued by issuers which (including  predecessors) have been
          in operation less than three years;

     (ix) invest  more  than 10% of the  Portfolio's  (ProFund's)  total  assets
          (taken at the greater of cost or market value) in securities  that are
          restricted  as to  resale  under  the 1933 Act  (other  than Rule 144A
          securities  deemed  liquid  by the  Portfolio's  (ProFund's)  Board of
          Trustees);

     (x)  with  respect  to 75% of the  Portfolio's  (ProFund'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;

     (xi) if the Portfolio (ProFund) 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 one issuer;

     (xii)purchase  or  retain  in the  Portfolio's  (ProFund's)  portfolio  any
          securities  issued  by an  issuer  any of whose  officers,  directors,
          trustees or security holders is an officer or Trustee of the Portfolio
          (Trust),  or is an officer or  partner  of the  Adviser,  if after the
          purchase of the securities of such issuer for the Portfolio  (ProFund)
          one or more of such persons owns  beneficially  more than 1/2 of 1% of
          the shares or securities,  or both, all taken at market value, of such
          issuer,  and such persons owning more than 1/2 of 1% of such shares or
          securities  together own  beneficially  more than 5% of such shares or
          securities, or both, all taken at market value;

     (xiii) invest  more than 5% of the  Portfolio's  (ProFund's)  net assets in
          warrants  (valued at the lower of cost or market) (other than warrants
          acquired by the  Portfolio  (ProFund) as part of a unit or attached to
          securities  at the  time of  purchase),  but not  more  than 2% of the
          Portfolio's  (ProFund's)  net assets may be invested  in warrants  not
          listed on the American Stock Exchange or the New York Stock  Exchange,
          Inc. ("NYSE");

     (xiv)make short sales of  securities or maintain a short  position,  unless

          without  payment of any further  consideration,  for securities of the
          same issue and equal in amount  to, the  securities  sold  short,  and
          unless  not more than 10% of the  Portfolio's  (ProFund's)  net assets
          (taken  at  market  value)  is  represented  by  such  securities,  or
          securities  convertible into or exchangeable  for such securities,  at
          any one time (the  Portfolio  (ProFund)  has no current  intention  to
          engage in short selling).

     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.

                      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.

     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.
<PAGE>

     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.

     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.
<PAGE>

     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 bases. 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.

                             MANAGEMENT OF PROFUNDS

     The Board of Trustees is  responsible  for the general  supervision  of the

Portfolio  subject to the  supervision and direction of the Board of Trustees of
the  Portfolio.  Bankers  Trust  will:  (i) act in  strict  conformity  with the

sale orders for  securities  and other  financial  instruments  on behalf of the
Portfolio.

     Bankers  Trust bears all expenses in  connection  with the  performance  of

Portfolio bear certain other expenses  incurred in their  operation,  including:
taxes, interest, brokerage fees and commissions, if any; fees of Trustees of the

relationships  with the issuers of obligations  which may be purchased on behalf
of the  Portfolio,  including  outstanding  loans to such issuers which could be
repaid in whole or in part with the proceeds of securities  so  purchased.  Such
affiliates deal, trade and invest for their own accounts in such obligations and
are among the  leading  dealers of various  types of such  obligations.  Bankers
Trust has informed the Portfolio  that, in making its investment  decisions,  it
does not obtain or use material  inside  information in its possession or in the
possession of any of its affiliates.  In making investment  recommendations  for
the Portfolio, Bankers Trust will not inquire or take into consideration whether
an issuer of  securities  proposed  for  purchase or sale by the  Portfolio is a
customer of Bankers Trust,  its parent or its subsidiaries or affiliates and, in
dealing  with its  customers,  Bankers  Trust,  its  parent,  subsidiaries,  and

provides  that  each  ProFund  will make  payments  equal to 1.00% (on an annual
basis) of the average  daily value of the net assets of such  ProFund's  Adviser
shares  attributable  to or held in the name of  investment  advisers  and other
authorized  institutions  that sell  Service  Shares  ("Authorized  Firms")  for
providing  account  administration  services to their clients who are beneficial
owners of such shares.  The  Administrator  may act as an Authorized  Firm.  The
Trust  will enter  into  agreements  ("Shareholder  Services  Agreements")  with
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.

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.

     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 year ended December 31, 1997,  each ProFund was entitled to,
and voluntarily waived, shareholder services fees in the following amounts:

                                    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
share.  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.

                                      
<PAGE>

     Each ProFund  intends to be taxed as a regulated  investment  company under
Subchapter M of the Code. 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;  (b) in each taxable year beginning before
August 6, 1997,  derive less than 30% of its gross income from the sale or other
disposition of certain assets held less than three months,  namely: (i) stock or
securities;  (ii) options,  futures,  or forward  contracts (other than those on
foreign  currencies)  that are not directly  related to the ProFund's  principal
business of  investing  in stock or  securities  (or  options  and futures  with
respect to stock or securities);  and (c) 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. The
ProFunds  expect  that such  distributions  will be taxable to  shareholders  as
long-term  capital  gain,  although  the matter is not free from doubt.  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.

                                  
<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 period  ended  December 31,
1997, since inception was as follows:

     This  performance data represents past performance and is not an indication
of future results. The UltraShort OTC ProFund, UltraEuro ProFund, and UltraShort
Euro ProFund had not commenced operations as of December 31, 1997.
    
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
expenses, and market conditions.

                                     
<PAGE>

         For the  seven-day  period  ended  December  31,  1997,  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,  the  UltraBear  ProFund,  the  UltraEuro  ProFund  and  the
UltraShort Euro 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 and the UltraShort OTC 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,  the
UltraBear  ProFund,  the UltraEuro  ProFund and the UltraShort  Euro ProFund and
from the "Small Company Growth  ProFunds"  grouping for the UltraOTC ProFund and
the UltraShort OTC 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
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 but 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.  Description of
Duff & Phelps' corporate bond ratings:

                                     
<PAGE>

     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.

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/VIMG-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.

     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.

                                    
<PAGE>

     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".

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

ITEM 27. Indemnification

                  The Registrant is organized as a Delaware business trust and
                  is operated pursuant to a Declaration of Trust, dated as of
                  April 17, 1997 (the "Declaration of Trust"), that permits the
                  Registrant to indemnify its trustees and officers under
                  certain circumstances. Such indemnification, however, is
                  subject to the limitations imposed by the Securities Act of
                  1933, as amended, and the Investment Company Act of 1940, as
                  amended. The Declaration of Trust of the Registrant provides
                  that officers and trustees of the Trust shall be indemnified
                  by the Trust against liabilities and expenses of defense in
                  proceedings against them by reason of the fact that they each
                  serve as an officer or trustee of the Trust or as an officer 
                  or trustee of another entity at the request of the entity. 
                  This indemnification is subject to the following conditions:
                  (a)      no trustee or officer of the Trust is indemnified
                           against any liability to the Trust or its security
                           holders which was the result of any willful
                           misconduct, bad faith, gross negligence, or reckless
                           disregard of his duties;

                  (b)      officers and trustees of the Trust are indemnified
                           only for actions taken in good faith which the
                           officers and trustees believed were in or not opposed
                           to the best interests of the Trust; and
                  (c)      expenses of any suit or proceeding will paid in
                           advance only if the persons who will benefit by such
                           advance undertake to repay the expenses unless it
                           subsequently is determined that such persons are
                           entitled to indemnification.

                  The Declaration of Trust of the Registrant provides that if
                  indemnification is not ordered by a court, indemnification may
                  be authorized upon determination by shareholders, or by a
                  majority vote of a quorum of the trustees who were not parties
                  to the proceedings or, if this quorum is not obtainable, if
                  directed by a quorum of disinterested trustees, or by
                  independent legal counsel in a written opinion, that the
                  persons to be indemnified have met the applicable standard.
