                                                                       Benchmark
                                                                        ProFunds


              Overview

                  The no-load Benchmark ProFunds each seek to achieve a daily
                  return equal to the performance of a particular stock market
                  benchmark.*
                  o For example, the Bull ProFund seeks to match the daily
                  performance of a stock market index--the S&P 500 Composite
                  Stock Price Index(R) ("S&P 500 Index")--like a conventional
                  index fund.
                  o Unlike conventional index funds, certain ProFunds seek to
                  double the daily return of a specified stock market index.
                  o Other ProFunds seek to produce a daily return of the inverse
                  (opposite) or double the inverse (opposite) of a particular
                  stock market index. The value of these ProFunds should go up
                  when the index underlying their benchmark goes down, and their
                  value should go down when the index goes up.

                 *A stock index reflects the price of a group of stocks of
                  specified companies. A benchmark can be any standard of
                  investment performance to which a mutual fund seeks to match
                  its return. For example, UltraBull ProFund has a benchmark of
                  twice the daily return of the S&P 500 Index.

2    Benchmark ProFunds

<PAGE>


           Benchmark ProFunds Objectives

                  The investment objective of each of the Benchmark ProFunds is
                  set forth below:

                  o Bull ProFund--seeks daily investment results that correspond
                  to the performance of the S&P 500 Index.

                  o UltraBull ProFund--seeks daily investment results that
                  correspond to twice (200%) the performance of the S&P 500
                  Index. If the UltraBull ProFund is successful in meeting its
                  objective, it should gain approximately twice as much as the
                  Bull ProFund when the prices of the securities in the S&P 500
                  Index rise on a given day and should lose approximately twice
                  as much when such prices decline on that day.

                  o UltraOTC ProFund--seeks daily investment results that
                  correspond to twice (200%) the performance of the NASDAQ 100
                  Index(TM). If the UltraOTC ProFund is successful in meeting
                  its objective, it should gain approximately twice as much as
                  the growth oriented NASDAQ 100 Index(TM) when the prices of
                  the securities in that index rise on a given day and should
                  lose approximately twice as much when such prices decline on
                  that day.

                  o UltraEurope ProFund--seeks daily investment results that
                  correspond to twice (200%) the performance of the ProFunds
                  Europe Index. If the UltraEurope ProFund is successful in
                  meeting its objective, it should gain approximately twice as
                  much as the ProFunds Europe Index when the prices of the
                  securities in that index rise on a given day and should lose
                  approximately twice as much when such prices decline on that
                  day.

                  o Bear ProFund--seeks daily investment results that correspond
                  to the inverse (opposite) of the performance of the S&P 500
                  Index. If the Bear ProFund is successful in meeting its
                  objective, the net asset value of Bear ProFund shares will
                  increase in direct proportion to any decrease in the level of
                  the S&P 500 Index. Conversely, the net asset value of Bear
                  ProFund shares will decrease in direct proportion to any
                  increase in the level of the S&P 500 Index.


                                                        Benchmark ProFunds     3

<PAGE>


                  o UltraBear ProFund--seeks daily investment results that
                  correspond to twice (200%) the inverse (opposite) of the
                  performance of the S&P 500 Index. The net asset value of
                  shares of the UltraBear ProFund should increase or decrease
                  approximately twice as much as does that of the Bear ProFund
                  on any given day.

[GRAPHIC APPEARS HERE]

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


                  o UltraShort OTC ProFund--seeks daily investment results that
                  correspond to twice (200%) the inverse (opposite) of the
                  performance of the NASDAQ 100 Index(TM). This ProFund operates
                  similar to the UltraBear ProFund, but UltraShort OTC ProFund
                  is benchmarked to the NASDAQ 100 Index(TM).


                  The securities indexes that these ProFunds use as their
                  benchmarks are described below under "Benchmark Indexes."



         Strategy
                  ProFund Advisors uses quantitative and statistical analysis it
                  developed in seeking to achieve each Benchmark ProFund's
                  investment objective. This analysis determines the type,
                  quantity and mix of investment positions that a Benchmark
                  ProFund should hold to approximate the performance of its
                  benchmark.




4 Benchmark ProFunds

<PAGE>



                  The Bull, UltraBull, UltraOTC and UltraEurope ProFunds
                  principally invest in:

                  o Futures contracts on stock indexes, and options on futures
                  contracts; and

                  o Financial instruments such as equity caps, collars, floors,
                  and options on securities and stock indexes.

                  These ProFunds invest in the above instruments generally as a
                  substitute for investing directly in stocks. In addition,
                  these ProFunds may invest in a combination of stocks that in
                  ProFund Advisors' opinion should simulate the movement of the
                  appropriate benchmark index.

                  The Ultra ProFunds generally invest in the above instruments
                  to produce economically "leveraged" investment results.
                  Leverage is a way to change small market movements into larger
                  changes in the value of a Benchmark ProFund's investments.

                  The Bear, UltraBear and UltraShort OTC ProFunds generally do
                  not invest in traditional securities, such as common stock of
                  operating companies. Rather, these ProFunds principally invest
                  in futures contracts, options contracts and other financial
                  instruments, and engage in short sales. Using these
                  techniques, these ProFunds will generally incur a loss if the
                  price of the underlying security or index increases between
                  the date of the employment of the technique and the date on
                  which the ProFund terminates the position. These ProFunds will
                  generally realize a gain if the underlying security or index
                  declines in price between those dates.

                  The UltraEurope ProFund invests in financial instruments with
                  values that reflect the performance of stocks of European
                  companies.

         Benchmark ProFunds' Risks

                  Like all investments, the ProFunds entail risk. ProFund
                  Advisors cannot guarantee that any of the Benchmark ProFunds
                  will achieve its objective. As with any mutual fund, the
                  Benchmark ProFunds could lose money, or their performance
                  could trail that of other investment alternatives.

                  In addition, the Benchmark ProFunds present some risks not
                  traditionally associated with most mutual funds. It is
                  important that investors closely review and understand these
                  risks before making an investment in the ProFunds.

                  The following chart summarizes certain risks associated with
                  the Benchmark ProFunds:


                         Market    Leverage     Inverse Correlation     Foreign

UltraShort OTC            X          X                 X



                  These and other risks are described below.


                  Certain Risks Associated with Particular ProFunds
                  o Leverage Risk The Ultra ProFunds employ leveraged investment
                  techniques. Leverage is the ability to get a return on a
                  capital base that is larger than a ProFund's investment. Use
                  of leverage can magnify the effects of changes in the value of
                  these ProFunds and makes them more volatile. The leveraged
                  investment

                  techniques that the Ultra ProFunds employ should cause
                  investors in these ProFunds to lose more money in adverse
                  environments.

                  o Inverse Correlation Risk Shareholders in the negatively
                  correlated ProFunds should lose money when the index
                  underlying their benchmark rises -- a result that is the
                  opposite from traditional equity mutual funds.
                  o Foreign Investment Risk UltraEurope ProFund entails the risk
                  of foreign investing, which may involve risks not typically
                  associated with investing in U.S. securities alone:
                    o Many foreign countries lack uniform accounting and
                    disclosure standards, or have standards that differ from
                    U.S. standards. Accordingly, the UltraEurope ProFund may not
                    have access to adequate or reliable company information.
                    o UltraEurope ProFund will be subject to the market,
                    economic and political risks of the countries where they
                    invest or where the companies represented in the benchmark
                    indexes are located.
                    o Securities purchased by the UltraEurope ProFund may be
                    priced in foreign currencies. Their value could change
                    significantly as the currencies strengthen or weaken
                    relative to the U.S. dollar. ProFund Advisors does not
                    engage in activities designed to hedge against foreign
                    currency fluctuations.
                    o On January 1, 1999, the eleven nations of the European
                    Monetary Union, including Germany and France, began the
                    process of introducing a uniform currency. The new currency,
                    the euro, is expected to reshape financial markets, banking
                    systems and monetary policy in Europe and throughout the
                    world. The continued transition to the euro may also have a
                    worldwide impact on the economic environment and behavior of
                    investors.

                  Risks in Common
                  Each Benchmark ProFund faces certain risks in common:

                  o Market Risk The Benchmark ProFunds are subject to market
                  risks that will affect the value of their shares, including
                  general economic and market conditions, as well as
                  developments that impact specific industries or companies.
                  Shareholders in the positively correlated ProFunds should lose
                  money when the index underlying their benchmark declines.
                  Shareholders in the negatively correlated ProFunds should lose
                  money when the index underlying their benchmark rises. These
                  indexes are discussed in the next section.

                  o Liquidity Risk In certain circumstances, such as a
                  disruption of the orderly markets for the financial
                  instruments in which ProFunds invest, ProFunds might not be
                  able to dispose of certain holdings quickly or at prices that
                  represent true market value in the judgment of ProFund
                  Advisors. This may prevent ProFunds from limiting losses or
                  realizing gains.

                  o Correlation Risk While ProFund Advisors expects that each of
                  the Benchmark ProFunds will track its benchmark with an
                  average correlation of .90 or better over a year, there can be
                  no guarantee that the ProFunds will be able to achieve this
                  level of correlation. A failure to achieve a high degree of
                  correlation may prevent a Benchmark ProFund from achieving its
                  investment goal.

                  o Non-Diversification Risk The Benchmark ProFunds are
                  classified as "non-diversified" under the federal securities
                  laws. They have the ability to concentrate a relatively high
                  percentage of their investments in the securities of a small
                  number of companies. This would make the performance of a
                  Benchmark ProFund more susceptible to a single economic,
                  political or regulatory event than a more diversified mutual
                  fund might be. Nevertheless, the Benchmark ProFunds intend to
                  invest on a diversified basis.

                  o Risks of Aggressive Investment Techniques The Benchmark
                  ProFunds use investment techniques that may be considered
                  aggressive. Risks associated with the use of options, futures
                  contracts, and options on futures contracts include
                  potentially dramatic price changes (losses) in the value of
                  the instruments and imperfect correlations between the price
                  of the contract and the underlying security or index.


Benchmark Indexes
                  o The S&P 500 Index is a widely used measure of large U.S.
                  company stock performance. It consists of the common stocks of
                  500 major corporations selected for their size and the
                  frequency and ease with which their stocks trade. Standard &
                  Poor's also attempts to assure that the Index reflects the
                  full range and diversity of the American economy. The
                  companies in the S&P 500 account for nearly three-quarters of
                  the value of all U.S. stocks.

                  o The NASDAQ 100 Index contains 100 of the largest and most
                  active non-financial domestic and international issues listed
                  on the NASDAQ Stock Market based on market capitalization.
                  Eligibility criteria for the NASDAQ 100 Index includes a
                  minimum average daily trading volume of 100,000 shares. If the
                  security is a foreign security, the company must have a world
                  wide market value of at least $10 billion, a U.S. market
                  value of at least $4 billion, and average trading volume of at
                  least 200,000 shares per day.

                  o ProFunds Europe Index ("PEI") is a combined measure of
                  European stock performance created by ProFund Advisors from
                  the leading stock indexes of Europe's three largest economies
                  giving equal weight to each index each day. The PEI averages
                  the daily results of:
                    o The Financial Times Stock Exchange 100 ("FTSE-100") Share
                    Index, a capitalization-weighted index of the 100 most
                    highly capitalized companies traded on the London Stock
                    Exchange.

                    o The Deutsche Aktienindex ("DAX"), is a total rate of
                    return index of 30 selected German blue-chip stocks traded
                    on the Frankfurt Stock Exchange.

                    o The CAC-40, a capitalization-weighted index of 40
                    companies listed on the Paris Stock Exchange (the Bourse).


                  ProFunds' Board of Trustees may change benchmarks without
                  shareholder approval if, for example, it believes another
                  benchmark might better suit shareholder needs.


         Who May Want to Consider a ProFunds Investment

                  The Bull ProFund may be appropriate for investors who want to
                  receive investment results approximating the performance of
                  the S&P 500 Index.

                  The UltraBull, UltraOTC and UltraEurope ProFunds may be
                  appropriate for investors who:
                  o believe that over the long term, the value of a particular
                  index will increase, and that by investing with the objective
                  of doubling the index's daily return they will achieve
                  superior results over time. Investors in these ProFunds should
                  understand that since each Ultra ProFund seeks to double the
                  daily performance of its benchmark index, it should have twice
                  the volatility of a conventional index fund and twice the
                  potential risk of loss.
                  o are seeking to match an index's daily return with half the
                  investment required of conventional stock index mutual funds.

                    An investor might invest $100,000 in a conventional S&P 500
                    Index Fund. Alternatively that same investor could invest
                    half that amount--$50,000--in UltraBull ProFund and target
                    the same daily return.


                  The Bear, UltraBear and UltraShort OTC ProFunds may be
                  appropriate for investors who:
                  o expect the underlying index to go down and desire to earn a
                  profit as a result of the index declining.
                  o want to protect (or hedge) the value of a diversified
                  portfolio of stocks and/or stock mutual funds from a stock
                  market downturn that they anticipate.


10 Benchmark ProFunds

<PAGE>


                  An investor with a diversified portfolio of stocks or stock
                  mutual funds valued at $100,000 might be concerned that the
                  general stock market could decrease or be volatile for the
                  next six months. The investor could try to protect the
                  portfolio against downturns in the stock market by investing
                  $50,000 in Bear, UltraBear or UltraShort OTC ProFund-or in a
                  combination of these ProFunds. Of course, the investor likely
                  would also be giving up gains that the portfolio would
                  otherwise produce if the markets go up rather than down in
                  value. ProFunds cannot assure that doing so would protect
                  against market downturns.


                  All of the ProFunds may be appropriate for investors who:
                  o are executing a strategy that relies on frequent buying,
                  selling or exchanging among stock mutual funds, since the
                  ProFunds do not limit how often an investor may exchange among
                  the ProFunds and do not impose any transaction fee when
                  investors buy, sell or exchange a ProFund.
                  o want the impact of their investment to range from double the
                  index to double the inverse of the index based on their
                  current view, positive or negative, of the index.

         Benchmark ProFunds' Performance

                  The bar chart and tables in this section can help you evaluate
                  the potential risks of investing in the Benchmark ProFunds.
                  The bar chart shows the 1998 return for the Investor Class
                  shares of each Benchmark ProFund available to the public for a
                  year or more as of December 31, 1998 (which excludes the newly
                  formed UltraShort OTC and UltraEurope ProFunds). The first
                  table compares each such ProFund's return for Investor Class
                  shares in 1998 and since inception with its relevant benchmark
                  index. The second table compares each such ProFund's return
                  for Service Class shares in 1998 and since inception with its
                  relevant benchmark index. Of course, how a Benchmark ProFund
                  has performed in the past is not necessarily an indication of
                  how it will perform in the future.

Expense Examples
                  The following examples illustrate the expenses you would have
                  incurred on a $10,000 investment in each Benchmark ProFund,
                  and are intended to help you compare the cost of investing in
                  the Benchmark ProFunds compared to other mutual funds. The
                  examples assume that you invested for the time periods shown
                  and redeemed all of your shares at the end of each period,
                  that each ProFund earns an annual return of 5% over the
                  periods shown, that you reinvest all dividends and
                  distributions, and that gross operating expenses remain
                  constant (1 year examples for Bull and Bear ProFunds reflect
                  current fee waivers). Because these examples are hypothetical
                  and for comparison only, your actual costs will be different.

What the Benchmark ProFunds Do

                  Each Benchmark ProFund:
                  o Seeks to provide its shareholders with predictable
                  investment returns approximating its benchmarks by investing
                  in securities and other financial instruments, such as futures
                  and options on futures.
                  o Uses a mathematical and quantitative approach.
                  o Pursues their objectives regardless of market conditions,
                  trends or direction.
                  o Seeks to provide correlation with their benchmarks on a
                  daily basis.



What the Benchmark ProFunds Do Not Do

                  ProFund Advisors does not:
                  o Conduct conventional stock research or analysis or forecast
                  stock market movement in managing the Benchmark ProFunds'
                  assets.
                  o Invest the Benchmark ProFunds' assets in stocks or
                  instruments based on ProFund Advisors' view of the fundamental
                  prospects of particular companies.
                  o Adopt defensive positions by investing in cash or other
                  instruments in anticipation of an adverse climate for the
                  ProFunds' benchmark indexes.
                  o Seek to invest to realize dividend income from their
                  investments.


                                                Benchmark ProFunds Strategy   17
<PAGE>



                  In addition, the Ultra ProFunds do not seek to provide
                  correlation with their benchmark over a period of time other
                  than daily, such as monthly or annually, since mathematical
                  compounding prevents these ProFunds from achieving such
                  results.



         Important Concepts

                  o Leverage offers a means of magnifying small market
                  movements, up or down, into large changes in an investment's
                  value.
                  o Futures, or futures contracts, are contracts to pay a fixed
                  price for an agreed-upon amount of commodities or securities,
                  or the cash value of the commodity or securities, on an
                  agreed-upon date.
                  o Option contracts grant one party a right, for a price,
                  either to buy or sell a security or futures contract at a
                  fixed sum during a specified period or on a specified day.
                  o Selling short, or borrowing stock to sell to a third party,
                  is a technique that may be employed by the ProFunds to seek
                  gains when their benchmark index declines. If the ProFund
                  replaces the security to the lender at a price lower than the
                  price it borrowed it at plus interest incurred, the ProFund
                  makes a profit on the difference. If the current market price
                  is greater when the time comes to replace the stock, the
                  ProFund will incur a loss on the transaction.

         Portfolio Turnover
                  ProFund Advisors expects a significant portion of the
                  Benchmark ProFunds' assets to come from professional money
                  managers and investors who use ProFunds as part of "market
                  timing" investment strategies. These strategies often call for
                  frequent trading of ProFund shares to take advantage of
                  anticipated changes in market conditions. Although ProFund
                  Advisors believes its accounting methodology should minimize
                  the effect on ProFunds of such trading, market timing trading
                  could increase the rate of ProFunds' portfolio turnover,
                  forcing realization of substantial capital gains and losses
                  and increasing transaction expenses. In addition, while
                  ProFunds does not expect it, large movements of assets into
                  and out of the ProFunds may negatively impact their abilities
                  to achieve their investment objectives or their level of
                  operating expenses.

                                                                         ProFund



          Objective
                  The Money Market ProFund invests its assets in the Cash
                  Management Portfolio (the "Portfolio"), a separate investment
                  company managed by Bankers Trust Company. This structure is
                  sometimes referred to as "master-feeder." The objective of the
                  Money Market ProFund and the Portfolio are identical: both
                  seek a high level of current income consistent with liquidity
                  and preservation of capital. The Portfolio seeks this
                  objective by investing in high quality short-term money market
                  instruments.



         Strategy
                  Money Market ProFund invests for current income. In order to
                  maintain a stable share price, the Portfolio maintains a
                  dollar-weighted average maturity of 90 days or less.
                  Generally, securities in the Portfolio are valued in U.S.
                  dollars and have remaining maturities of 397 days (about 13
                  months) or less on their purchase date. The Portfolio may also
                  invest in securities that have features that reduce their
                  maturities to 397 days or less on their purchase date. The
                  Portfolio buys U.S. government debt obligations, money market
                  instruments and other debt obligations that at the time of
                  purchase:
                  o have received the highest short-term rating from two
                  nationally recognized statistical rating organizations; or
                  o have received the highest short-term rating from one rating
                  organization (if only one organization rates the security);


                                                       Money Market ProFund   21
<PAGE>


                  o if unrated, are determined to be of similar quality by the
                  Portfolio's investment advisor; or
                  o have no short-term rating, but are rated in the top three
                  highest long-term rating categories, or are determined to be
                  of similar quality by the Portfolio's investment advisor.



         Risks
                  All money market instruments, including U.S. government debt
                  obligations, are subject to interest rate risk, which is the
                  risk that an investment will change in value when interest
                  rates change. Generally, investments subject to interest rate
                  risk will decrease in value when interest rates rise and
                  increase when interest rates decline.

                  Money market instruments are subject to credit risk, which is
                  the risk that the issuer of the instrument will default, or
                  fail to meet its payment obligations. In addition, they may
                  change in value if an issuer's creditworthiness changes,
                  although such a circumstance would be extremely unlikely in
                  the case of U.S. government debt obligations.

                  The Money Market ProFund also will be subject to the effects
                  of business, economic and regulatory developments that affect
                  the Portfolio or the financial services industry generally.

                  An investment in the Money Market ProFund is not a deposit of
                  a bank, nor is it insured or guaranteed by the Federal Deposit
                  Insurance Corporation or any other government agency. While
                  the Money Market ProFund tries to maintain a stable net asset
                  value of $1.00 per share, there is no guarantee that the Money
                  Market ProFund will do so, and you could lose money by
                  investing in this ProFund.

         Considering a Money Market ProFund Investment

                  Investors can take advantage of the Money Market ProFund in
                  two ways:
                  o during periods when investors want to maintain a neutral
                  exposure to the stock market, the income earned from an
                  investment in the Money Market ProFund can keep their capital
                  at work.
                  o the Money Market ProFund can be invested in conjunction with
                  other ProFunds to adjust an investor's target exposure to an
                  index.

                    For instance, an investor who desires to target a daily
                    return of 1.5 times the daily performance of the S&P 500
                    Index could allocate 75% of his or her investment to the
                    UltraBull ProFund and 25% of the investment to the Money
                    Market ProFund.



         Money Market ProFund's Total Returns and Expenses

                  The bar chart and tables in this section can help you evaluate
                  the potential risk of investing in Money Market ProFund. The
                  bar chart shows the 1998 return for the Investor Class shares
                  of the Money Market ProFund. The first table shows the Money
                  Market ProFund's return for Investor Class shares in 1998 and
                  since inception. The second table shows the return for Service
                  Class shares in 1998 and since inception. Of course, how the
                  Money Market ProFund has performed in the past is not
                  necessarily an indication of how it will perform in the
                  future.

                  Investor Class shares was Q4 1998 (1.22%), and its lowest
                  quarterly return was Q3 1998 (1.14%).

                  Expense Examples
                  The examples below illustrate the expenses you would have
                  incurred on a $10,000 investment in each class of shares of
                  the Money Market ProFund, and are intended to help you compare
                  the cost of investing in the ProFund compared to other mutual
                  funds. The examples assume that you invested for the time
                  periods shown and redeemed all of your shares at the end of
                  each period, that the Money Market ProFund earns an annual
                  return of 5% over the periods shown, that you reinvest all
                  dividends and distributions, and that gross operating expenses

                  comparison only, your actual costs will be different.

                                                                        strategy


                  The Money Market ProFund invests all of its investable assets
                  in the Portfolio. The Portfolio may invest in high-quality,
                  short-term, dollar-denominated money market securities paying
                  a fixed, variable or floating interest rate. These include:
                  o Debt securities issued by U.S. and foreign banks, financial
                  institutions, and corporations, including certificates of
                  deposit, euro-time deposits, commercial paper (including
                  asset-backed commercial paper), notes, funding agreements and
                  U.S. government securities. Securities that do not satisfy the
                  maturity restrictions for a money market fund may be
                  specifically structured so that they are eligible investments
                  for money market funds. For example, some securities have
                  features which have the effect of shortening the security's
                  maturity.
                  o U.S. government securities that are issued or guaranteed by
                  the U.S. Treasury, or by agencies or instrumentalities of the
                  U.S. Government.
                  o Repurchase agreements, which are agreements to buy
                  securities at one price, with a simultaneous agreement to sell
                  back the securities at a future date at an agreed-upon price.
                  o Asset-backed securities, which are generally participations
                  in a pool of assets whose payment is derived from the payments
                  generated by the underlying assets. Payments on the
                  asset-backed security generally consist of interest and/or
                  principal.

                  Because many of the Portfolio's principal investments are
                  issued or credit-enhanced by banks, the Portfolio may invest
                  more than 25% of its total assets in obligations of domestic
                  banks.

                  The Portfolio may invest in other types of instruments, as
                  described in the Statement of Additional Information.


        Specific Risks and Measures Taken to Limit Them

                  Credit Risk

                  A money market instrument's credit quality depends on the
                  issuer's ability to pay interest on the security and repay the
                  debt: the lower the credit rating, the greater the risk that
                  the security's issuer will default, or fail to meet its
                  payment obligations. The credit risk of a security may also
                  depend on the credit quality of any bank or financial
                  institution that provides credit enhancement for it. The
                  Portfolio only buys high quality securities with minimal
                  credit risk. If a security no longer meets the Portfolio's
                  credit rating requirements, Bankers Trust Company will attempt
                  to sell that security within a reasonable time, unless selling
                  the security would not be in the Portfolio's best interest.

                  Repurchase Agreement Risk

                  A repurchase agreement exposes the Portfolio to the risk that
                  the party that sells the securities defaults on its obligation
                  to repurchase them. In this circumstance, the Portfolio can
                  lose money because:
                  o it may not be able to sell the securities at the agreed-upon
                  time and price.
                  o the securities lose value before they can be sold.

                  Bankers Trust Company seeks to reduce the Portfolio's risk by
                  monitoring, under the supervision of the Portfolio's Board of
                  Trustees, the creditworthiness of the sellers with whom it
                  enters into repurchase agreements. The Portfolio also monitors
                  the value of the securities to ensure that they are at least
                  equal to the total amount of the repurchase obligations,
                  including interest.

                  Interest Rate Risk

                  Money market instruments, like all debt securities, face the
                  risk that the securities will decline in value because of
                  changes in interest rates. Generally, investments subject to
                  interest rate risk will decrease in value when interest rates
                  rise and increase when interest rates decline. To minimize
                  such price fluctuations, the Portfolio adheres to the
                  following practices:
                  o Bankers Trust Company limits the dollar-weighted average
                  maturity of the securities held by the Portfolio to 90 days or
                  less. Generally, rates of short-term investments fluctuate
                  less than longer-term bonds.
                  o Bankers Trust Company primarily buys securities with
                  remaining maturities of 13 months or less. This reduces the
                  risk that the issuer's creditworthiness will change, or that
                  the issuer will default on the principal and interest payments
                  of the obligations.


                  Market Risk

                  Although individual securities may outperform their market,
                  the entire market may decline as a result of rising interest
                  rates, regulatory developments or deteriorating economic
                  conditions.


                  Security Selection Risk

                  While the Portfolio invests in short-term securities, which by
                  nature are relatively stable investments, the risk remains
                  that the securities selected will not perform as expected.
                  This could cause the Portfolio's returns to lag behind those
                  of similar money market funds. Bankers Trust Company attempts
                  to limit this risk by diversifying the Portfolio's investments
                  so that a single setback need not undermine the pursuit of its
                  objective and by investing in money market instruments that
                  receive the highest short-term debt ratings as described
                  above.


                  Concentration Risk

                  Because the Portfolio may invest more than 25% of its total
                  assets in the financial services industry, it may be
                  vulnerable to setbacks in that industry. Banks and other
                  financial service

                                             Money Market ProFund Strategy    29
<PAGE>


                  companies are highly dependent on short-term interest rates
                  and can be adversely affected by downturns in the U.S. and
                  foreign economies or changes in banking regulations.


                  Prepayment Risk

                  When a bond issuer, such as an issuer of asset-backed
                  securities, retains the right to pay off a high-yielding bond
                  before it comes due, the Portfolio may have no choice but to
                  reinvest the proceeds at lower interest rates. Thus,
                  prepayment may reduce the Portfolio's income. It may also
                  create a capital gains tax liability, because bond issuers
                  usually pay a premium for the right to pay off bonds early.



         Organizational Structure

                  The Money Market ProFund is a feeder fund that invests all of
                  its assets in a master fund, the Portfolio. The ProFund and
                  the Portfolio have the same investment objective.

                  The Portfolio may accept investments from other feeder funds.
                  The feeders bear the Portfolio's expenses in proportion to
                  their assets. Each feeder can set its own transaction
                  minimums, fund-specific expenses and other conditions. The
                  Money Market ProFund's Trustees may withdraw its assets from
                  the Portfolio if they believe doing so is in the shareholders'
                  best interests. If the Trustees withdraw the Fund's assets,
                  they would then consider whether the Fund should hire its own
                  investment advisor and invest its assets directly in
                  appropriate instruments, invest in a different fund, or take
                  other action.

             Calculating the ProFunds' Share Prices

                  Except for the UltraEurope ProFund, each Benchmark ProFund
                  calculates daily share prices on the basis of the net asset
                  value of each class of shares at the close of regular trading
                  on the New York Stock Exchange ("NYSE") (normally, 4:00 p.m.,
                  Eastern time) every day the NYSE and the Chicago Mercantile
                  Exchange are open for business.

                  The UltraEurope ProFund calculates daily share prices on the
                  basis of the net asset value of each class of shares at the
                  latest close of trading on the three exchanges tracked by the
                  PEI: the London Stock Exchange, the Frankfurt Stock Exchange
                  or the Paris Bourse (normally, 11:30 a.m., Eastern time), on
                  each day that all three of these exchanges and the NYSE are
                  open.

                  Purchases and redemptions of shares are effected at the net
                  asset value per share next determined after receipt and
                  acceptance of an order. If portfolio investments of a ProFund
                  are traded in markets on days when the ProFund's principal
                  trading market(s) is closed, the ProFund's net asset value may
                  vary on days when investors cannot purchase or redeem shares.

                  The ProFunds value shares of each class of shares by dividing
                  the market value of the assets attributable to each class,
                  less the liabilities attributable to the class, by the number
                  of the class's

                  outstanding shares. The ProFunds use the following methods for
                  arriving at the current market price of investments held by
                  the Benchmark ProFunds:
                  o securities listed and traded on exchanges--the last price
                  the stock traded at on a given day, or if there were no sales,
                  the mean between the closing bid and asked prices.
                  o securities traded over-the-counter--NASDAQ-supplied
                  information on the prevailing bid and asked prices.
                  o futures contracts and options on indexes and securities--the
                  last sale price prior to the close of regular trading on the
                  NYSE (for all Benchmark ProFunds except UltraEurope ProFund).
                  o futures prices used to calculate net asset values for the
                  UltraEurope ProFund will be the last transaction prices for
                  the respective futures contracts that occur immediately prior
                  to the close of the underlying stock exchange.
                  o options on futures contracts--priced at fair value
                  determined with reference to established future exchanges.
                  o bonds and convertible bonds generally are valued using a
                  third-party pricing system.
                  o short-term debt securities are valued at amortized cost,
                  which approximates market value.
                  o the foreign exchange rates used to calculate the net asset
                  values for the UltraEurope ProFund will be the mean of the bid
                  price and the asked price for the respective foreign currency
                  occurring immediately before the last underlying stock
                  exchange closes.

                  When price quotes are not readily available, securities and
                  other assets are valued at fair value in good faith under
                  procedures established by, and under the general supervision
                  and responsibility of, the ProFunds' Board of Trustees. This
                  procedure incurs the unavoidable risk that the valuation may
                  be higher or lower than the securities might actually command
                  if the ProFunds sold them. In the event that a trading halt
                  closes the NYSE or a futures exchange early, portfolio
                  investments may be valued at fair value, or in a manner that
                  is different from the discussion above. See the Statement of
                  Additional Information for more details.

         Calculating the Money Market ProFund's Share Price

                  The Money Market ProFund calculates daily share prices on the
                  basis of the net asset value of each class of shares at the
                  close of regular trading on the NYSE (normally, 4:00 p.m.,
                  Eastern time) every day the NYSE is open for business except
                  for two additional bank holidays, Columbus Day and Veterans'
                  Day. Purchases and redemptions of shares are effected at the
                  net asset value per share next determined after receipt and
                  acceptance of an order. If the market for the primary
                  investments in the Portfolio closes early,

<PAGE>


                  the Portfolio may close early. The Money Market ProFund will
                  cease taking purchase orders at that time. The Money Market
                  ProFund's net asset value per share for each class of shares
                  will normally be $1.00, although neither ProFund Advisors nor
                  Bankers Trust Company can guarantee that this will always be
                  the case. The Portfolio uses the amortized cost method to
                  account for any premiums or discounts above or below the face
                  value of any securities it buys. This method does not reflect
                  daily fluctuations in market value.



         Dividends and Distributions

                  Each of the Benchmark ProFunds intends to distribute to its
                  shareholders every year all of the year's net investment
                  income and net capital gains. Each Benchmark ProFund will
                  reinvest these distributions in additional shares unless a
                  shareholder has written to request a direct cash distribution.

                  The Money Market ProFund declares dividends from its net
                  income daily and pays the dividends on a monthly basis. The
                  Money Market ProFund will pay annually any long-term capital
                  gains as well as any short-term capital gains that it did not
                  distribute during the year, but it reserves the right to
                  include in the daily dividend any short-term capital gains on
                  securities that it sells.

                  The Money Market ProFund may revise these policies, postpone
                  the payment of dividends and interest or take other actions in
                  order to maintain a constant net asset value of $1.00 per
                  share.



         Tax Consequences

                  A ProFund does not ordinarily pay income tax on its net
                  investment income (which includes short-term capital gains)
                  and net capital gain that it distributes to shareholders, but
                  individual shareholders pay tax on the dividends and
                  distributions they receive. Shareholders will generally be
                  taxed regardless of how long they have held ProFund shares and
                  regardless of whether

                  they receive cash or choose to have distributions and
                  dividends reinvested. Distributions and dividends generally
                  will be taxable as either ordinary income or long-term capital
                  gains. For example, if a ProFund designates a particular
                  distribution as a long-term capital gain distribution, it will
                  be taxable to shareholders at their long-term capital gain
                  rate. Dividends and distributions may also be subject to state
                  and local taxes.

                  Every year the ProFunds will send shareholders tax information
                  on the dividends and distributions for the previous year.

                  If shareholders sell or redeem their ProFund shares, they may
                  have a capital gain or loss, which will be long-term or
                  short-term, generally depending upon how long they have held
                  the shares. An exchange of ProFund shares may be treated as a
                  sale.

                  The tax consequences for tax deferred retirement accounts or
                  non-taxable shareholders will be different.


                  Please keep in mind:
                  o Whether a distribution by a ProFund is taxable to
                  shareholders as ordinary income or at the lower capital gains
                  rate depends on whether it is long-term capital gains of the
                  ProFund, not on how long an investor has owned shares of the
                  ProFund.
                  o Dividends and distributions declared by a ProFund in
                  October, November or December of one year and paid in January
                  of the next year may be taxable in the year the ProFund
                  declared them.
                  o As with all mutual funds, a ProFund may be required to
                  withhold U.S. federal income tax at the rate of 31% of all
                  taxable distributions and redemption proceeds, payable to
                  shareholders who fail to provide the ProFund with correct
                  taxpayer identification numbers or to make required
                  certifications, or who have been notified by the IRS that they
                  are subject to backup withholding. Backup withholding is not
                  an additional tax; rather, it is a way in which the IRS
                  ensures it will collect taxes otherwise due. Any amounts
                  withheld may be credited against the shareholder's U.S.
                  federal income tax liability. You also may be subject to a $50
                  fee to reimburse the ProFunds for any penalty that the IRS may
                  impose.

                  Please see the Statement of Additional Information for more
                  information. Because each investor's tax circumstances are
                  unique and because the tax laws are subject to change, ProFund
                  Advisors recommends that shareholders consult their tax
                  advisors about federal, state, local and foreign tax
                  consequences of investment in the ProFunds.



         Classes of Shares

                  Investors in any of the ProFunds can purchase either Investor
                  Class shares directly, or Service Class shares through an
                  authorized firm, such as a registered investment advisor, a
                  bank or a trust company. Under a shareholder services plan for
                  Service Class shares, each ProFund may pay an authorized firm
                  up to 1.00% on an annualized basis of average daily net assets
                  attributable to its customers who are Service Class
                  shareholders. For this fee, the authorized firms may provide a
                  variety of services, such as:
                  o receiving and processing shareholder orders,
                  o performing the accounting for the shareholder's account,
                  o maintaining retirement plan accounts,
                  o answering questions and handling correspondence for
                    individual accounts,
                  o acting as the sole shareholder of record for individual
                    shareholders,
                  o issuing shareholder reports and transaction confirmations,
                  o executing daily investment "sweep" functions, and
                  o investment advisory services.

                  Holders of a ProFund's Service Class shares pay all fees and
                  expenses applicable to these shares. The authorized firms may
                  charge extra for services beyond those specified above, but
                  they must furnish clients who own Service Class shares with a
                  schedule explaining those fees.

                  Establishing Accounts For Tax-Sheltered Retirement Plans
                  The ProFunds sponsor Individual Retirement Accounts ("IRAs")
                  that enable individual investors to set up their own
                  retirement savings programs. ProFund Advisors charges an
                  annual fee of $15 per social security number for all types of
                  IRAs to pay for the extra maintenance and tax reporting that
                  these plans require. Investors in other types of retirement
                  plans also may invest in the ProFunds. For additional
                  information and an application, contact ProFunds directly by

                  Please keep in mind when purchasing shares:
                  o The minimum subsequent purchase amount is $100.
                  o ProFunds prices shares you purchase at the price per share
                  next computed after we receive and accept your purchase order
                  in good order. In order to be in good order, a purchase order
                  must include a properly completed application and wire, check
                  or other form of payment.
                  o A wire order is considered in good order only if (i) you
                  have called ProFunds under the procedures described above and
                  (ii) ProFunds receives and accepts your wire. ProFunds only
                  accepts wires during the times it processes wires: between
                  8:00 a.m. and 3:30 p.m., Eastern time for all ProFunds except
                  that UltraEurope ProFund does not receive and process wires
                  from 10:30 a.m. through 11:30 a.m., Eastern time. Wires
                  received after ProFunds' wire processing times will be
                  processed as of the next time that orders are processed. If
                  the primary exchange or market, on which a ProFund transacts
                  business closes early, the above cut-off time will be 25
                  minutes prior to the close of such exchange or market.
                  o If your purchase is cancelled, you will be responsible for
                  any losses that may result from any decline in the value of
                  the cancelled purchase. ProFunds (or its agents) have the
                  authority to redeem shares in your account(s) to cover any
                  losses due to fluctuations in share price. Any profit on a
                  cancelled transaction will accrue to the ProFunds.
                  o Securities brokers and dealers have the responsibility of
                  transmitting your orders promptly. Brokers and dealers may
                  charge transaction fees on the purchase and/or sale of
                  ProFunds shares.

              Exchanges

                  Shareholders can exchange shares of either class of any
                  ProFund for shares of either class of another ProFund,
                  including the ProFunds not described in this prospectus, free
                  of charge. ProFunds can only honor exchanges between accounts
                  registered in the same name, and having the same address and
                  taxpayer identification number.

                  ProFunds accepts exchange orders by phone, in writing or
                  through the Internet, except that the ProFunds does not accept
                  exchange orders through the Internet for the UltraEurope
                  ProFund. You will need to specify the number of shares, or the
                  percentage or dollar value of the shares you wish to exchange,
                  and the ProFunds (and classes of shares) involved in the
                  transaction.

                  By telephone: Exchange orders between ProFunds can be accepted
                  by phone between 8:00 a.m. and 3:50 p.m. and between 4:30 p.m.
                  and 9:00 p.m., Eastern time, with the exception that ProFunds
                  does not accept exchange orders involving the UltraEurope
                  ProFund between 10:30 a.m. and 11:30 a.m., Eastern time. If
                  the primary exchange or market (generally, the CME) on which a
                  ProFund (other than the UltraEurope ProFund) transacts
                  business closes early, the above cut-off time will be 25
                  minutes prior to the close of such exchange or market.

                  By Internet: Shareholders may transact on-line exchanges of
                  shares of the ProFunds, except exchanges of shares of the
                  UltraEurope ProFund, at ProFunds' website (www.profunds.com).
                  To access this service through the website, click on the
                  "Trade/Access Account" Icon and you will be prompted to enter
                  your Social Security Number. Follow the instructions to
                  establish your Personal Identification Number (PIN) which will
                  allow you to execute exchanges between ProFunds and access
                  ProFunds account information. Internet exchange orders between
                  the ProFunds can be accepted between 8:00 a.m. and 3:55 p.m.
                  and between 4:30 p.m. and 9:00 p.m., Eastern time. If the

                  to the close of such exchange or market.

                  Internet exchange transactions are extremely convenient, but
                  are not free from risk. To ensure that all Internet
                  transactions are safe, secure and as risk-free as possible,
                  ProFunds has instituted certain safeguards and procedures for
                  determining the identity of website users. As a result,
                  neither ProFunds nor its transfer agent will be responsible
                  for any loss, liability, cost or expense for following
                  Internet instructions they reasonably believe to be genuine.
                  If you or your intermediary make exchange requests by the
                  Internet, you will generally bear the risk of loss.

                  The ProFunds may terminate the ability to exchange ProFund
                  shares on its website at any time, in which case you may
                  continue to exchange shares by phone or in writing.


                  Please keep in mind when exchanging shares:

                  o An exchange actually is a redemption (sale) of shares of one
                  ProFund and a purchase of shares of another ProFund.
                  o If both ProFunds involved in the exchange have their
                  respective net asset values calculated at the same time then
                  both the sale and the buy will occur simultaneously.

                    For example, assume you were to exchange Money Market
                    ProFund for UltraOTC ProFund and the order was placed before
                    3:50 p.m., Eastern time, on any business day. The net asset
                    values for both ProFunds involved in the transaction are
                    computed at the same time. Therefore, both the price of the
                    shares sold out of Money Market ProFund and the shares
                    purchased into UltraOTC ProFund would be determined
                    simultaneously when the net asset values are next computed,
                    normally 4:00 p.m., Eastern time.


                  o If the exchange involves ProFunds that calculate their net
                  asset values at different times, you will receive the net
                  asset value next computed for the redemption transaction. The
                  purchase transaction will receive the price next determined
                  after the redemption transaction is completed, with one
                  exception as described below. The proceeds from the redemption
                  transaction

                                                                     Shareholder
                                                                  Services Guide


                  will not be invested during the intervening period and will
                  not earn interest during that time.

                    For example, assume you were to exchange UltraBull ProFund
                    for UltraEurope ProFund and the order was placed before 3:50
                    p.m., Eastern time, on a business day of the UltraBull
                    ProFund. The net asset values of UltraEurope and UltraBull
                    ProFunds are not determined at the same time. As a result,
                    the components of the exchange would be valued at two
                    different times. First, the sale from UltraBull ProFund
                    would be priced using the next computed net asset value,
                    which would be determined normally at 4:00 p.m., Eastern
                    time, on such day. Second, the buy into UltraEurope ProFund
                    would receive the net asset value of UltraEurope ProFund
                    next determined after the redemption from UltraBull ProFund.
                    That determination of the net asset value of UltraEurope
                    ProFund would normally take place at 11:30 a.m., Eastern
                    time, on the next business day of UltraEurope ProFund.

                  An exception to the above exchange transaction policies covers
                  exchange requests from the Money Market ProFund to the
                  UltraEurope ProFund, from after 4:00 p.m. on one business day
                  until 10:30 a.m. the next business day. In such an exchange,
                  you will receive the price next computed after the exchange
                  request is made for both the redemption and the purchase
                  transactions involved in the exchange. You will be responsible
                  for any losses if sufficient redemption proceeds are not
                  available to pay the purchase price of shares purchased.
                  o Please note that during certain periods, it may take several
                  days for exchanges to be completed due to holidays.
                  o The minimum exchange for self-directed accounts is $1,000
                  or, if less, for the account's current value.
                  o You may exchange, on a regular basis, shares of the Money
                  Market ProFund for shares of other ProFunds through an
                  Automatic Exchange Plan. For more information on this option,
                  please call ProFunds at 888-776-3637.

                  o Before executing an exchange between the Profunds described
                  in this prospectus for shares of another ProFund, a
                  shareholder must first review the prospectus related to the
                  other ProFund. Such prospectus may be obtained by contacting
                  the ProFunds by letter or telephone at the address or phone
                  number noted on the back cover of this prospectus, or by
                  visiting the ProFunds' website (www.profunds.com).

         Redeeming ProFund Shares

                  You can redeem all or part of your shares at the price next
                  determined after we receive your request. ProFunds other than
                  UltraEurope ProFund only accept redemption orders by phone
                  between 8:00 a.m. and 3:50 p.m. and between 4:30 p.m. and 9:00
                  p.m., Eastern time. UltraEurope ProFund accepts telephone
                  redemption orders only between 8:00 a.m. and 10:30 a.m. and
                  11:30 a.m. and 9:00 p.m., Eastern time. ProFunds may not
                  receive or accept phone redemption orders at any other time.
                  If the primary exchange or market on which a ProFund (other
                  than the UltraEurope ProFund) transacts business closes early,
                  the above cut-off time will be 25 minutes prior to the close
                  of such exchange or market.


                  Written Redemptions
                  To redeem all or part of your shares in writing, your request
                  needs to include the following information:
                  o the name of the ProFund(s),
                  o the account number(s),
                  o the amount of money or number of shares being redeemed,
                  o the name(s) of the account owners,
                  o the signature(s) of all registered account owners, and
                  o your daytime telephone number.

                  Wire Redemptions
                  If your account is authorized for wire redemption, your
                  proceeds will be wired directly into the bank account you have
                  designated. The ProFunds charge a $15 service fee for a wire
                  transfer of redemption proceeds, and your bank may charge an
                  additional fee to receive the wire. If you would like to
                  establish this option on an existing account, please call
                  ProFunds to request the appropriate form. Wire redemptions are
                  not available for retirement accounts.

                  Signature Guarantee
                  Certain redemption requests must include a signature
                  guarantee. Your request needs to be in writing and include a
                  signature guarantee if any of the following situations apply:
                  o Your account registration or address has changed within the
                  last 30 calendar days.
                  o The check is being mailed to a different address than the
                  one on your account.
                  o The check or wire is being made payable to someone other
                  than the account owner.
                  o The redemption proceeds are being transferred to an account
                  with a different registration.
                  o You wish to redeem more than $100,000.
                  o You are adding or changing wire instructions on your
                  account.
                  o Other unusual situations as determined by ProFund's transfer
                  agent.

                  Signature guarantees may be provided by an eligible guarantor
                  institution such as a commercial bank, an NASD member firm
                  such as a stock broker, a savings association or a national
                  securities exchange.

                  Please keep in mind when redeeming shares:
                  o Redemptions from self-directed accounts must be for at least
                  $1,000 or, if less, for the account's entire current value.
                  The remaining balance needs to be above the applicable minimum
                  investment.
                  o The ProFunds normally remit redemption proceeds within seven
                  days of redemption. For redemption of shares purchased by
                  check or Automatic Investment, ProFunds may wait up to 15 days
                  before sending redemption proceeds to assure that its transfer
                  agent has collected the purchase payment.
                  o ProFunds will remit payment of telephone redemptions only to
                  the address or bank of record on the account application. You
                  must submit, in writing, a request for payment to any other
                  address, along with a signature guarantee from a financial
                  service organization.

                  o To redeem shares in a retirement account, your request needs
                  to be in writing, except for exchanges to other ProFunds,
                  which can be requested by phone or in writing. Call the
                  ProFunds to request a retirement distribution form.
                  o Involuntary Redemptions: ProFunds reserves 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 redemption.
                  In addition, both a request for a partial redemption by an
                  investor whose account balance is below the minimum investment
                  and a request for partial redemption by an investor that would
                  bring the account below the minimum investment will be treated
                  as a request by the investor for a complete redemption of the
                  account.
                  o Redemption proceeds from the UltraEurope ProFund are made
                  within seven business days after the business date of the
                  redemption. The business date of these redemptions may be the
                  business day following the day your redemption request reaches
                  ProFunds.
                  o Money Market ProFund shares begin accruing dividends on the
                  day ProFund's transfer agent, BISYS Fund Services, receives a
                  purchase order and payment in the form of a Federal funds
                  wire. Purchases by check begin earning dividends the business
                  day following the business day the check is received. They
                  continue to earn dividends until the business day that BISYS
                  Fund Services has processed the redemption order.


                  Suspension of Redemptions
                  Your right of redemption may be suspended, or the date of
                  payment postponed: (i) for any period during which the NYSE or
                  the Federal Reserve Bank of New York is closed (other than
                  customary weekend or holiday closings) or trading on the NYSE,
                  as appropriate, is restricted, as determined by the Securities
                  and Exchange Commission; (ii) for any period during which an
                  emergency exists, as

                  determined by the Securities and Exchange Commission, 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 Securities and Exchange
                  Commission, by order, may permit for protection of ProFunds'
                  investors.


                  Draft Checks
                  You may elect to redeem shares of the Money Market ProFund by
                  draft check ($500 minimum) made payable to the order of any
                  person or institution. If you are interested in this option,
                  you must submit a completed signature card to ProFunds. You
                  will then be supplied with draft checks that are drawn on the
                  Money Market ProFund's account. There is a $25 fee for stop
                  payment requests on draft checks. This option is not available
                  to Individual Retirement Account shareholders.



         Automatic Investment and Redemption Plans

                  Shareholders may buy and redeem shares automatically on a
                  monthly, bimonthly, quarterly or annual basis. The minimum
                  automatic purchase is $100 and the minimum automatic
                  redemption is $500. These minimums are waived for IRA
                  shareholders 70 1/2 years of age or older.


         About Telephone Transactions

                  o It may be difficult to reach ProFunds by telephone during
                  periods of heavy market activity or other times. If you are
                  unable to reach us by telephone, consider sending written
                  instructions.
                  o You may initiate numerous transactions by telephone. Please
                  note, however, that the ProFunds and their agents will not be
                  responsible for losses resulting from unauthorized
                  transactions when procedures designed to verify the identity
                  of the caller are followed.

                  Advisors LLC, has more than 29 years of experience in the
                  commodity futures markets. His background includes a five-year
                  presidential appointment as a commissioner of the U.S.
                  Commodity Futures Trading Commission. He earned his degrees at
                  University of Kentucky. Dr. Seale also holds an appointment as
                  Professor of Finance at George Washington University.

                  Each Benchmark ProFund is managed by an investment team
                  chaired by Dr. Seale.


                  Bankers Trust Company
                  The Money Market ProFund seeks to achieve its investment
                  objective by investing all of its assets in a portfolio
                  managed by Bankers Trust Company, with headquarters at 130
                  Liberty Street, New York, NY 10006. Bankers Trust makes the
                  Portfolio's investment decisions and assumes responsibility
                  for the securities the Portfolio owns. It receives a fee equal
                  to 0.05% of the average daily net assets of the Portfolio.

                  As of December 31, 1998, Bankers Trust was the eighth largest
                  bank holding company in the United States, with total assets
                  of approximately $156 billion. Bankers Trust Company is a
                  worldwide merchant bank dedicated to servicing the needs of
                  corporations, governments, financial institutions and private
                  clients through a global network of over 96 offices in more
                  than 43 countries.

                  Bankers Trust Company is a wholly owned subsidiary of Bankers
                  Trust Corporation. On June 4, 1999, Bankers Trust Corporation
                  merged with a subsidiary of Deutsche Bank AG ("Deutsche
                  Bank"). Shareholders of the Money Market ProFund, which
                  invests its assets in Cash Management Portfolio (the
                  "Portfolio"),

                  voted at a Special Meeting of Shareholders to approve a new
                  investment advisory agreement (the "Advisory Agreement")
                  between the Portfolio and Bankers Trust Company ("Bankers
                  Trust"). Approval of the Advisory Agreement was sought because
                  Deutsche Bank became Bankers Trust's parent company, and
                  therefore, controls its operations as investment adviser.
                  Under the new investment advisory agreement, the compensation
                  paid and the services provided would be the same as those
                  under the Advisory Agreement with Bankers Trust. Deutsche Bank
                  AG is a major global banking institution that is engaged in a
                  wide range of financial services, including investment
                  management, mutual funds, retail and commercial banking,
                  investment banking and insurance.


         Other Service Providers

                  BISYS Fund Services, located at 3435 Stelzer Road, Suite 1000,
                  Columbus, Ohio 43219, acts as the administrator to the
                  ProFunds, providing operations, compliance and administrative
                  services. Each ProFund pays BISYS a fee, on a sliding scale,
                  for its administrative services. For average daily net assets
                  up to $300 million, the fee is 0.15% of the assets, and it
                  declines to 0.05% for average daily net assets of $1 billion
                  or more.

                  ProFund Advisors also performs client support and
                  administrative services for the ProFunds. The Benchmark
                  ProFunds each paid a fee of 0.15% of average daily net assets
                  for these services last year. ProFund Advisors may receive a
                  fee of 0.35% of average daily net assets from the Money Market
                  ProFund for these services and for feeder fund management,
                  administration and reporting in its relationship to the
                  Portfolio.


         Year 2000

                  Like other funds and business organizations around the world,
                  the ProFunds could be adversely affected if the computer
                  systems used by their investment advisors and other service
                  providers do not properly process and calculate date-related
                  information for the Year 2000 and beyond. In addition, Year
                  2000 issues may

<PAGE>



                  adversely affect companies in which the ProFunds invest, which
                  could impact the prices of the ProFunds' shares.

                  The ProFunds have been assured that their 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. The service providers are likewise seeking assurances
                  from their respective vendors and suppliers that these
                  entities are addressing any Year 2000 issues.

                  In the event that any systems upon which the ProFunds depend
                  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 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 investment advisors and other service
                  providers will not be completed by December 31, 1999. The
                  ProFunds will continue to closely monitor developments
                  relating to this issue.

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

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

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

     This Statement of Additional Information is not a prospectus. It should be
read in conjunction with ProFunds' Prospectus, dated May 1, 1999, which
incorporates this Statement of Additional Information by reference. The
financial statements and related report of the independent accountants included
in the Fund's annual report for the fiscal year ended December 31, 1998 are
incorporated by reference into this Statement of Additional Information. A copy

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


                       INVESTMENT POLICIES AND TECHNIQUES

GENERAL

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

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

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

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

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

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

                                       3

THE BULL PROFUND AND ULTRABULL PROFUND

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

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

THE BEAR PROFUND AND ULTRABEAR PROFUND

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

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

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

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

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

     Under these techniques, the Bear ProFund and the UltraBear ProFund will
generally incur a loss if the price of the underlying security or index
increases between the date of the employment of the technique and the date on
which the ProFund terminates the position. These ProFunds will generally realize
a gain if the underlying security or index declines in price between those
dates. The amount of any gain or loss on an investment

                                       4
<PAGE>

technique may be affected by any premium or amounts in lieu of dividends or
interest that the ProFund pays or receives as the result of the transaction.

THE ULTRAOTC PROFUND AND THE ULTRASHORT OTC PROFUND

     The investment objective of the UltraOTC ProFund is to provide investment
results that correspond to 200% of the performance of the NASDAQ 100 Index(TM).

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

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

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

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

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

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

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

     Companies whose securities are traded on the over-the-counter ("OTC")
markets generally have smaller market capitalization or are newer companies than
those listed on the NYSE or the American Stock Exchange (the "AMEX"). OTC
companies often have limited product lines, or relatively new products or
services, and may lack established markets, depth of experienced management, or
financial resources and the ability to generate

                                       5
<PAGE>

funds. The securities of these companies may have limited marketability and may
be more volatile in price than securities of larger capitalized or more
well-known companies. Among the reasons for the greater price volatility of
securities of certain smaller OTC companies are the less certain growth
prospects of comparably smaller firms, the lower degree of liquidity in the OTC
markets for such securities, and the greater sensitivity of smaller
capitalization companies to changing economic conditions than larger
capitalization, exchange-traded securities. Conversely, because many of these
OTC securities may be overlooked by investors and undervalued in the
marketplace, there is potential for significant capital appreciation.

THE ULTRAEUROPE PROFUND

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

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

     Investing in foreign companies or financial instruments by the UltraEurope
ProFund (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 the
UltraEurope ProFund will invest indirectly in foreign markets, it will be
subject to the market, economic and political risks prevalent in these foreign
markets.

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

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

THE MONEY MARKET PROFUND

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

     The Money Market ProFund seeks to achieve its investment objective by
investing its assets in the Portfolio, which has the same investment objective
as the Money Market ProFund and is managed by Bankers

                                       6
<PAGE>
Trust, 130 Liberty St. (One Bankers Trust Plaza), New York, New York 10006.
There can be no assurance that the investment objective of either the Money
Market ProFund or the Portfolio will be achieved. The investment objectives of
the Money Market ProFund and the Portfolio are fundamental policies and may not
be changed without the approval of the Money Market ProFund's shareholders or
the Portfolio's investors, respectively. See "Special Information Concerning
MasterFeeder Fund Structure" herein.

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

FUTURES CONTRACTS AND RELATED OPTIONS

     The ProFunds (other than the Money Market ProFund) may purchase or sell
stock index futures contracts and options thereon as a substitute for a
comparable market position in the underlying securities or to satisfy regulation
requirements. A futures contract obligates the seller to deliver (and the
purchaser to take delivery of) the specified commodity on the expiration date of
the contract. A stock index futures contract obligates the seller to deliver
(and the purchaser to take) an amount of cash equal to a specific dollar amount
multiplied by the difference between the value of a specific stock index at the
close of the last trading day of the contract and the price at which the
agreement is made. No physical delivery of the underlying stocks in the index is
made.

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

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

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

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

                                       7
<PAGE>

of the underlying security exceeds the exercise price of the call option), the
in-the-money amount may be excluded in calculating this 5% limitation.

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

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

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

INDEX OPTIONS

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

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

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

     The non-money market ProFunds may engage in transactions in stock index
options listed on national securities exchanges or traded in the
over-the-counter market as an investment vehicle for the purpose of realizing
the ProFund's investment objective. Options on indexes are settled in cash, not
by delivery of securities. The exercising holder of an index option receives,
instead of a security, cash equal to the difference between the closing price of
the securities index and the exercise price of the option.

     Some stock index options are based on a broad market index such as the S&P
500 Index, the NYSE Composite Index, or the AMEX Major Market Index, or on a
narrower index such as the Philadelphia Stock Exchange Over-the-Counter Index.
Options currently are traded on the Chicago Board Options Exchange (the "CBOE"),
the AMEX, and other exchanges ("Exchanges"). Purchased over-the-counter options
and the cover for written over-the-counter options will be subject to the
respective ProFund's 15% limitation on investment in illiquid securities. See
"Illiquid Securities."

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

OPTIONS ON SECURITIES

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

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

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

                                       10
<PAGE>

be imposed with respect to particular classes or series of options; (iv) unusual
or unforeseen circumstances may interrupt normal operations on an exchange; (v)
the facilities of an exchange or the OCC may not at all times be adequate to
handle current trading volume; or (vi) one or more exchanges could, for economic
or other reasons, decide or be compelled at some future date to discontinue the
trading of options (or a particular class or series of options) would cease to
exist, although outstanding options on that exchange that had been issued by the
OCC as a result of trades on that exchange would continue to be exercisable in
accordance with their terms.

SHORT SALES

     The Bear ProFund, the UltraBear ProFund and the UltraShort OTC ProFund may
engage in short sales transactions under which the ProFund sells a security it
does not own. To complete such a transaction, the ProFund must borrow the
security to make delivery to the buyer. The ProFund then is obligated to replace
the security borrowed by purchasing the security at the market price at the time
of replacement. The price at such time may be more or less than the price at
which the security was sold by the ProFund. Until the security is replaced, the
ProFund is required to pay to the lender amounts equal to any dividends or
interest which accrue during the period of the loan. To borrow the security, the
ProFund also may be required to pay a premium, which would increase the cost of
the security sold. The proceeds of the short sale will be retained by the
broker, to the extent necessary to meet the margin requirements, until the short
position is closed out.

     Until the ProFund closes its short position or replaces the borrowed
security, the ProFund will cover its position with an offsetting position or
maintain a segregated account containing cash or liquid instruments at such a
level that the amount deposited in the account plus the amount deposited with
the broker as collateral will equal the current value of the security sold
short.

SWAP AGREEMENTS

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

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

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

                                       11
<PAGE>

     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.

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

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

     The use of equity swaps is a highly specialized activity which involves
investment techniques and risks different from those associated with ordinary
portfolio securities transactions.

U.S. GOVERNMENT SECURITIES

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

     Yields on U.S. government securities are dependent on a variety of factors,
including the general conditions of the money and bond markets, the size of a
particular offering, and the maturity of the obligation. Debt securities with
longer maturities tend to produce higher yields and are generally subject to
potentially greater capital appreciation and depreciation than obligations with
shorter maturities and lower yields. The market value of U.S. government
securities generally varies inversely with changes in market interest rates. An
increase in interest rates, therefore, would generally reduce the market value
of a ProFund's portfolio investments in U.S. government securities, while a
decline in interest rates would generally increase the market value of a
ProFund's portfolio investments in these securities.

     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

                                       12
<PAGE>
Association, the Government National Mortgage Association, the Small Business
Administration, the Federal Farm Credit Administration, the Federal Home Loan
Banks, Banks for Cooperatives (including the Central Bank for Cooperatives),the
Federal Land Banks, the Federal Intermediate Credit Banks, the Tennessee Valley
Authority, the Export-Import Bank of the United States, the Commodity Credit
Corporation, the Federal Financing Bank, the Student Loan Marketing Association,
and the National Credit Union Administration. Some obligations issued or
guaranteed by U.S. government agencies and instrumentalities, including, for
example, Government National Mortgage Association pass-through certificates, are
supported by the full faith and credit of the U.S. Treasury. Other obligations
issued by or guaranteed by Federal agencies, such as those securities issued by
the Federal National Mortgage Association, are supported by the discretionary
authority of the U.S. government to purchase certain obligations of the federal
agency, while other obligations issued by or guaranteed by federal agencies,
such as those of the Federal Home Loan Banks, are supported by the right of the
issuer to borrow from the U.S. Treasury. While the U.S. government provides
financial support to such U.S. government-sponsored Federal agencies, no
assurance can be given that the U.S. government will always do so, since the
U.S. Government is not so obligated by law. U.S. Treasury notes and bonds
typically pay coupon interest semi-annually and repay the principal at maturity.

REPURCHASE AGREEMENTS

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

CASH RESERVES

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

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

                                       13
<PAGE>

transactions are advantageous only if the interest cost to the ProFund/Portfolio
of the reverse repurchase transaction is less than the cost of obtaining the
cash otherwise. Opportunities to achieve this advantage may not always be
available, and the ProFund/Portfolios intend to use the reverse repurchase
technique only when it will be to the ProFund/Portfolio's advantage to do so and
the Money Market ProFund will not invest more than 5% of its total assets in
reverse repurchase agreements. The ProFund/Portfolios will establish a
segregated account with their custodian bank in which the ProFund/Portfolio will
maintain cash or liquid instruments equal in value to the ProFund/Portfolio's
obligations in respect of reverse repurchase agreements.

BORROWING

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

     As required by the Investment Company Act of 1940, as amended (the "1940
Act"), a ProFund must maintain continuous asset coverage (total assets,
including assets acquired with borrowed funds, less liabilities exclusive of
borrowings) of 300% of all amounts borrowed. If at any time the value of the
ProFund's assets should fail to meet this 300% coverage test, the ProFund,
within three days (not including Sundays and holidays), will reduce the amount
of the ProFund's borrowings to the extent necessary to meet this 300% coverage.
Maintenance of this percentage limitation may result in the sale of portfolio
securities at a time when investment considerations otherwise indicate that it
would be disadvantageous to do so. In addition to the foregoing, the ProFunds
are authorized to borrow money from a bank as a temporary measure for
extraordinary or emergency purposes in amounts not in excess of 5% of the value
of the ProFund's total assets. This borrowing is not subject to the foregoing
300% asset coverage requirement. The ProFunds are authorized to pledge portfolio
securities as the Advisor deems appropriate in connection with any borrowings.

LENDING OF PORTFOLIO SECURITIES

     Subject to the investment restrictions set forth below, each of the
ProFunds and the Portfolio may lend its portfolio securities to brokers,
dealers, and financial institutions, provided that cash equal to at least 100%
of the market value of the securities loaned is deposited by the borrower with
the ProFund/Portfolio and is maintained each business day in a segregated
account pursuant to applicable regulations. While such securities are on loan,
the borrower will pay the lending ProFund/Portfolio any income accruing thereon,
and the ProFund/Portfolio may invest the cash collateral in portfolio
securities, thereby earning additional income. A ProFund/Portfolio will not lend
more than 33 1/3 of the value of the ProFund's total assets, except that the
Portfolio will not lend more than 20% of the value of its total assets. Loans
would be subject to termination by the lending ProFund/Portfolio on four
business days' notice, or by the borrower on one day's notice. Borrowed
securities must be returned when the loan is terminated. Any gain or loss in the
market price of the borrowed securities which occurs during the term of the loan
inures to the lending ProFund/Portfolio and that ProFund's/Portfolio's
shareholders. There may be risks of delay in receiving additional collateral or
risks of delay in recovery of the securities or even loss of rights in the
securities lent should the borrower of the securities fail financially. A
lending ProFund/Portfolio may pay reasonable finders, borrowers, administrative,
and custodial Trustees in connection with a loan. With respect to the Portfolio,
cash collateral may be invested in a money market

                                       14
<PAGE>
fund managed by Bankers Trust (or its affiliate) and Bankers Trust may serve as
the Portfolio's lending agent and may share in revenue received from securities
lending transactions as compensation for this service.

WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES

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

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

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

INVESTMENTS IN OTHER INVESTMENT COMPANIES

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

ILLIQUID SECURITIES

     While none of the ProFunds anticipates doing so, each of the ProFunds and
the Portfolio may purchase illiquid securities, including securities that are
not readily marketable and securities that are not registered ("restricted
securities") under the Securities Act of 1933, as amended (the "1933 Act"), but
which can be sold to qualified institutional buyers under Rule 144A of the 1933
Act. A ProFund will not invest more than 15% (10% with respect to the Portfolio)
of the ProFund's/Portfolio's net assets in illiquid securities. The term
"illiquid securities" for this purpose means securities that cannot be disposed
of within seven days in the ordinary course of business at approximately the
amount at which the ProFund has valued the securities. Under the current
guidelines of the staff of the Securities and Exchange Commission (the
"Commission"),illiquid securities also are considered to include, among other
securities, purchased over-the-counter options, certain cover for
over-the-counter options, repurchase agreements with maturities in excess of
seven days, and certain securities whose disposition is restricted under the
Federal securities laws. The ProFund/Portfolio may not be able to sell illiquid
securities when the Advisor or Bankers Trust considers it desirable to do so or
may have to sell such

                                       15
<PAGE>

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.

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

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

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

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

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

     The Portfolio may invest in U.S. dollar-denominated fixed rate or variable
rate obligations of U.S. or foreign institutions, including banks which are
rated in the highest short-term rating category by any two NRSROs (or one NRSRO
if that NRSRO is the only such NRSRO which rates such obligations) or, if not so
rated, are believed by Bankers Trust, acting under the supervision of the Board
of Trustees of the Portfolio, to be of comparable quality. Bank obligations in
which the Portfolio invests include certificates of deposit, bankers'
acceptances, time

                                       16
<PAGE>
deposits, commercial paper, and other U.S. dollar-denominated instruments issued
or supported by the credit of U.S. or foreign institutions including banks. For
purposes of the Portfolio's investment policies with respect to bank
obligations, the assets of a bank will be deemed to include the assets of its
domestic and foreign branches. Obligations of foreign branches of U.S. banks and
foreign banks may be general obligations of the parent bank in addition to the
issuing bank or may be limited by the terms of a specific obligation and by
government regulation. If Bankers Trust, acting under the supervision of the
Portfolio's Board of Trustees, deems the instruments to present minimal credit
risk, the Portfolio may invest in obligations of foreign banks or foreign
branches of U.S. banks which include banks located in the United Kingdom, Grand
Cayman Island, Nassau, Japan and Canada. Investments in these obligations may
entail risks that are different from those of investments in obligations of U.S.
domestic banks because of differences in political, regulatory and economic
systems and conditions. These risks include, without limitation, future
political and economic developments, currency blockage, the possible imposition
of withholding taxes on interest payments, possible seizure or nationalization
of foreign deposits, and difficulty or inability of pursuing legal remedies and
obtaining judgment in foreign courts, possible establishment of exchange
controls or the adoption of other foreign governmental restrictions that might
affect adversely the payment of principal and interest on bank obligations.
Foreign branches of U.S. banks and foreign banks may also be subject to less
stringent reserve requirements and to different accounting, auditing, reporting
and recordkeeping standards than those applicable to branches of U.S. banks.
Under normal market conditions, the Portfolio will invest more than 25% of its
assets in the foreign and domestic bank obligations described above. The
Portfolio's concentration of its investments in bank obligations will cause the
Portfolio to be subject to the risks peculiar to the domestic and foreign
banking industries to a greater extent than if its investments were not so
concentrated. A description of the ratings set forth above is provided in the
Appendix.

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


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

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

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

                                       17
<PAGE>

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

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

PORTFOLIO TURNOVER

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

SPECIAL CONSIDERATIONS

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

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

                                       18
<PAGE>

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

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

SPECIAL INFORMATION CONCERNING MASTER-FEEDER FUND STRUCTURE

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

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

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

                                       19
<PAGE>

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

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

                             INVESTMENT RESTRICTIONS

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

     A non-money market ProFund may not:

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

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

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

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

                                       20

         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.

     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.

                                       21
<PAGE>

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

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

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

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

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

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

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

         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.

                                       22
<PAGE>

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

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

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

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

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

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

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

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

                                       23
<PAGE>

                  (ProFund's) Board of Trustees have determined that the
                  commercial paper is equivalent quality and is liquid;

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

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

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

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

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

DETERMINATION OF NET ASSET VALUE

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

     The net asset values of the shares of the UltraEurope ProFund are
determined as of the latest close of trading on three exchanges tracked by the
PEI (ordinarily 11:30 a.m. Eastern Time) on each day the NYSE, London Stock
Exchange, Frankfurt Stock Exchange and Paris Stock Exchange are open for
business (see prospectus for applicable holiday closings).

     To the extent that portfolio securities of a ProFund are traded in other
markets on days when the ProFund's principal trading market(s) is closed, the
ProFund's net asset value may be affected on days when investors do not have
access to the ProFund to purchase or redeem shares.

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

     The Portfolio will utilize the amortized cost method in valuing its
portfolio securities. This method involves valuing each security held by the
Portfolio at its cost at the time of its purchase and thereafter assuming

                                       24
<PAGE>

a constant amortization to maturity of any discount or premium. Accordingly,
immaterial fluctuations in the market value of the securities held by the
Portfolio will not be reflected in the Money Market ProFund's net asset value.
The Board of Trustees of the Portfolio will monitor the valuation of assets of
this method and will make such changes as it deems necessary to assure that the
assets of the Portfolio are valued fairly in good faith.

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

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

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

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

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

NON-MONEY MARKET PROFUNDS

     Subject to the general supervision by the Trustees, the Advisor is
responsible for decisions to buy and sell securities for each of the ProFunds,
the selection of brokers and dealers to effect the transactions, and the
negotiation of brokerage commissions, if any. The Advisor expects that the
ProFunds may execute brokerage or other agency transactions through registered
broker-dealers, for a commission, in conformity with the 1940 Act, the
Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder. The Advisor may serve as an investment manager to a number of
clients, including other investment companies. It is the practice of the Advisor
to cause purchase and sale transactions to be allocated among the ProFunds and
others whose assets the Advisor manages in such manner as the Advisor deems
equitable. The main factors considered by the Advisor in making such allocations
among the ProFunds and other client accounts of the Advisor are the respective
investment objectives, the relative size of portfolio holdings of the same or
comparable securities, the availability of cash for investment, the size of
investment commitments generally held, and the opinions of the person(s)
responsible, if any, for managing the portfolios of the ProFunds and the other
client accounts.

     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

                                       25
<PAGE>
lowest possible commission cost could impede effective portfolio management and
preclude the ProFund and the Advisor from obtaining a high quality of brokerage
and research services. In seeking to determine the reasonableness of brokerage
commissions paid in any transaction, the Advisor relies upon its experience and
knowledge regarding commissions generally charged by various brokers and on its
judgment in evaluating the brokerage and research services received from the
broker effecting the transaction. Such determinations are necessarily subjective
and imprecise, as in most cases an exact dollar value for those services is not
ascertainable.

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

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

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

MONEY MARKET PROFUND AND THE PORTFOLIO

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

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

     OTC 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

                                       26
<PAGE>

rules adopted by the Commission, broker-dealers may not execute transactions on
the floor of any national securities exchange for the accounts of affiliated
persons, but may effect transactions by transmitting orders for execution.

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

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

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

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

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

     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.

                                       27
<PAGE>

The percentage so determined will then be applied to determine the value of the
investor's interest in the Portfolio as of the close of the following business
day.

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

SHAREHOLDER SERVICES PLAN

     Each ProFund has adopted a Shareholder Services Plan (the "Plan") which
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. The ProFunds may pay
different service fee amounts to Authorized Firms, which may provide different
levels of services to their clients or customers.

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

     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.

          ORGANIZATION AND DESCRIPTION OF SHARES OF BENEFICIAL INTEREST

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

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

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

The Declaration of Trust of the ProFunds disclaims liability of the shareholders
or the officers of the Trust for acts or obligations of the Trust which are
binding only on the assets and property of the Trust. The Declaration of Trust
provides for indemnification of the Trust's property for all loss and expense of
any ProFunds shareholder held personally liable for the obligations of the
Trust. The risk of a Trust shareholder incurring financial loss on account of
shareholder liability is limited to circumstances in which loss of account of
shareholder liability is limited to

circumstances in which the ProFunds itself would not be able to meet the Trust's
obligations and this risk, thus, should be considered remote.

                                    TAXATION

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

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

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

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

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

                                       41
<PAGE>
     A dividend or capital gains distribution with respect to shares of a
ProFund held by a tax-deferred or qualified plan, such as an IRA, retirement
plan or corporate pension or profit sharing plan, will not be taxable to the
plan. Distribution from such plans will be taxable to individual participants
under applicable tax rules without regard to the character of the income earned
by the qualified plan.

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

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

     As a RIC, 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."

                                       42
<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.

                                       43
<PAGE>

PASSIVE FOREIGN INVESTMENT COMPANIES

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

DISTRIBUTIONS

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

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

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

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

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.

                                       45
<PAGE>

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

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

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

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

YIELD CALCULATIONS

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

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

                                       46
<PAGE>

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

COMPARISONS OF INVESTMENT PERFORMANCE

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

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

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

RATING SERVICES

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

                                    APPENDIX

                        DESCRIPTION OF SECURITIES RATINGS

DESCRIPTION OF S&P'S CORPORATE RATINGS:

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

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

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

DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS:

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

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

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

DESCRIPTION OF FITCH INVESTORS SERVICE'S CORPORATE BOND RATINGS:

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

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

                                       49
<PAGE>

DESCRIPTION OF DUFF & PHELPS' CORPORATE BOND RATINGS:

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

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

DESCRIPTION OF S&P'S MUNICIPAL BOND RATINGS:

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

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

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

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

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

DESCRIPTION OF MOODY'S MUNICIPAL BOND RATINGS:

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

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

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

DESCRIPTION OF S&P'S MUNICIPAL NOTE RATINGS:

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

                                       50
<PAGE>

DESCRIPTION OF MOODY'S MUNICIPAL NOTE RATINGS:

     Moody's ratings for state and municipal notes and other short-term loans
are designated Moody's Investment Grade (MIG) and for variable rate demand
obligations are designated Variable Moody's Investment Grade (VMIG). This
distinction recognizes the differences between short-term credit risk and
long-term risk. Loans bearing the designation MIG-1/VMIG-1 are of the best

and interest will be paid on a timely basis.

grade and therefore speculative. DESCRIPTION OF THOMSON BANKWATCH LONG-TERM

     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.

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".
