Overview and Investment Objectives

         Each of the no-load ProFunds described in this prospectus  ("ProFunds")
         seeks a daily return equal to double of the performance of a particular
         stock market index.*

         .UltraSmall-Cap   ProFund  -  seeks  daily   investment   results  that
         correspond  to twice  (200%) the  performance  of the  Russell  2000(R)
         Index.

         .UltraMid-Cap  ProFund - seeks daily investment results that correspond
         to  twice  (200%)  the  performance  of the S&P  MidCap  400  Index(R).

         .UltraJapan ProFund - seeks daily investment results that correspond to
         twice (200%) the performance of the Nikkei 225 Stock Average.

         If a ProFund is successful is in meeting its objective,  it should gain
         approximately  twice as much as its benchmark  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.

         *  The securities indexes that the ProFunds use as their benchmark are
            described below under "Benchmark Index."

Strategy

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

         The ProFunds may invest in stocks that ProFund  Advisors believe should
         simulate the movement of the applicable  underlying index. In addition,
         the ProFunds may invest in the  following  instruments  as a substitute
         for  investing  directly in stocks,  achieving  leverage  and for other
         purposes:

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

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

         The  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
         ProFund's investments.

         The UltraJapan  ProFund  invests in financial  instruments  with values
         that  reflect  the   performance   of  certain  stocks  of  Japan-based
         companies.

Investment Risks

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

         In  addition,   the  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
ProFunds:

                                                                                        Small
                                                                                   Capitalization    Mid-Capitalization
                           Market Risk       Leverage Risk      Foreign Risk            Risk               Risk
UltraSmall-Cap                    X                  X                                    X
UltraMid-Cap                      X                  X                                                      X
UltraJapan                        X                  X                 X

         These and other risks are described below.

Certain Risks Associated with Particular ProFunds

 .Small  Company  Investment  Risk the  UltraSmall-Cap  ProFund could  experience
greater risks than a fund which invests primarily in large  capitalized,  widely
traded companies, such as:

         . Small company stocks tend to have greater  fluctuations in price than
         the stocks of large companies.

         . There can be a shortage  of  reliable  information  on certain  small
         companies, which at times can pose a risk.

         . Small companies tend to lack the financial and personnel resources to
         handle  industry wide setbacks and as a result such setbacks could have
         a greater effect on the companies share price.

         . Small  company  stocks are  typically  less liquid then large company
         stocks and liquidating  positions in turbulent market  conditions could
         become difficult.

 .Mid-Cap Company Investment Risk The UltraMid-Cap ProFund could experience risks
that  a fund  which  invests  in  primarily  large  capitalized,  widely  traded
companies would not. Such risks could include:

         . Mid-Cap  company  stocks tend to have greater  fluctuations  in price
         than the stocks of large companies, but not as drastic as the stocks of
         small companies.

         . Stocks of mid-sized  companies  could be more  difficult to liquidate
         during  market  downturns   compared  to  larger,   more  widely-traded
         companies.

 .Foreign  Investment  Risk The  UltraJapan  ProFund  entails the risk of foreign
investing,  which may involve risks not typically  associated  with investing in
U.S. securities alone:

         . Japan has accounting  and disclosure  standards that differ from U.S.
         standards. Accordingly, this ProFund may not have access to adequate or
         reliable company information.
<PAGE>

         . The  UltraJapan  ProFund will be subject to the market,  economic and
         political  risks  of the  countries  where  it  invests  or  where  the
         companies represented in the benchmark index are located.

         .  Securities  purchased  by this  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.

Risks in Common

Each ProFund faces certain risks in common:

         . Leverage Risk The 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 the  ProFunds  and makes them more
         volatile.  The leveraged investment techniques that the ProFunds employ
         should cause  investors in these ProFunds to lose more money in adverse
         environments.

         . Market Risk The 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  should  lose money when the index  underlying
         their  benchmark  declines.  These  indexes are  discussed  in the next
         section.

         . Liquidity Risk In certain circumstances,  such as a disruption of the
         orderly  markets for the  financial  instruments  in which the ProFunds
         invest,  the 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 the ProFunds from limiting losses
         or realizing gains.

         .  Correlation  Risk While  ProFund  Advisors  expects that each of the
         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  ProFund  from  achieving  its
         investment goal.

         .   Non-Diversification   Risk   The   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,  if
         ProFund  Advisors  determines that doing so is the most efficient means
         of tracking the relevant benchmark.  This would make the performance of
         a  ProFund  more  susceptible  to  a  single  economic,   political  or
         regulatory  event  than  a  more  diversified  mutual  fund  might  be.
         Nevertheless, the ProFunds intend to invest on a diversified basis.

         . Risks of Aggressive Investment Techniques The 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

         .The Russell  2000(R) Index is an unmanaged  index  consisting of 2,000
         small company common stocks.  The Index comprises 2,000 of the smallest
         U.S.  domiciled  publicly traded common stocks that are included in the
         Russell 3000(R) Index.  These common stocks represent  approximately 8%
         of the total market  capitalization of the Russell 3000(R) Index which,
         in turn,  represents  approximately  98% of the  publicly  traded  U.S.
         equity market.
<PAGE>

         .The S&P  MidCap  400  Index(R)  is a widely  used  measure  of  medium
         capitalized U.S. company stock  performance.  It consists of the common
         stocks  of 400  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 Nikkei 225 Stock Average is a  price-weighted  index of 225 large,
         actively traded Japanese stocks traded on the Tokyo Stock Exchange. The
         index is computed and distributed by the Nihon Keizai Shimbun (NKS).

         ProFunds' Board of Trustees may change a ProFund's investment objective
         without  shareholder  approval  if, for  example,  it believes  another
         benchmark might better suit shareholder needs.

Who May Want to Consider a ProFunds Investment

         The ProFunds may be appropriate for investors who:

         . 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 the  ProFunds  should  understand  that since each 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.

         . 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  Russell  2000(R)
         Index Fund.  Alternatively  that same  investor  could invest half that
         amount--$50,000--in  the  UltraSmall-Cap  ProFund  and  target the same
         daily return.
         -----------------------------------------------------------------------

         All of the ProFunds may be appropriate  for investors who 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.

ProFunds' Performance

         Because the  ProFunds  are newly  formed and have no  investment  track
         record,  they have no performance to compare against other mutual funds
         or broad measures of securities market performance, such as indexes.

Annual ProFund Operating Expenses

         The tables below  describe the estimated  fees and expenses you may pay
         if you buy and hold shares of the  ProFunds  during their first year of
         operations.  The ProFunds are "no-load"  mutual funds. You pay no sales
         charge when you buy or sell shares, or when you reinvest dividends.

Note:  The ProFunds  charge $15 for each wire transfer of  redemption  proceeds;
this charge may be waived at the discretion of the ProFunds.

Expense Examples

         The following examples  illustrate the expenses you would have incurred
         on a $10,000  investment in each ProFund,  and are intended to help you
         compare the cost of investing in the ProFunds  compared to other mutual
         funds.  The examples  assume that you invest for the time periods shown
         and  redeem  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.  Because these examples are hypothetical and
         for comparison only, your actual costs will be different.

ProFunds Strategy

What the ProFunds Do

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

What the ProFunds Do Not Do

         ProFund Advisors does not:
         o Conduct  conventional  stock  research or analysis or forecast  stock
         market  movement  in  managing  the  ProFunds'  assets.
         . Invest the ProFunds' assets in stocks or instruments based on ProFund
         Advisors' view of the fundamental prospects of particular companies.
         . Adopt defensive  positions by investing in cash or other  instruments
         in anticipation of an adverse climate for their benchmark indexes.
         . Seek to invest to realize dividend income from their investments.
         . Seek to provide  correlation  with the  ProFunds'  benchmarks  over a
         period of time other than  daily,  such as monthly or  annually,  since
         mathematical  compounding  prevents the ProFunds  from  achieving  such
         results.

Important Concepts

         . Leverage offers a means of magnifying small market  movements,  up or
         down, into large changes in an investment's value.
         . 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.
         . 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
         .  American   Depository   Receipts  represent  the  right  to  receive
         securities  of foreign  issuers  deposited in a bank or trust  company.
         ADRs are an  alternative  to purchasing  the  underlying  securities in
         their national  markets and currencies.  Investment in ADRs has certain
         advantages over direct investment in the underlying  foreign securities
         since: (i) ADRs are U.S. dollar-denominated investments that are easily
         transferable and for which market quotations are readily available, and
         (ii) issuers whose  securities  are  represented  by ADRs are generally
         subject to  auditing,  accounting  and  financial  reporting  standards
         similar to those applied to domestic issuers.

Portfolio Turnover

         ProFund Advisors expects a significant  portion of the 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 the  ProFunds  do 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.

Share Prices, Classes and Tax Information

Calculating the ProFunds' Share Prices

         Each  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.

         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  ProFunds:

         . 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.
         . securities  traded  over-the-counter--NASDAQ-supplied  information on
         the prevailing bid and asked prices.
         . futures  contracts  and options on indexes and  securities--the  last
         sale price prior to the close of regular trading on the NYSE.
         . options on futures  contracts--priced  at fair value  determined with
         reference to established future exchanges.
         . bonds and convertible  bonds generally are valued using a third-party
         pricing system.
         .  short-term  debt  securities  are valued at  amortized  cost,  which
         approximates market value.

         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.

         The New York Stock  Exchange  and the Chicago  Mercantile  Exchange,  a
         leading  market for futures and  options,  are open every week,  Monday
         through Friday, except when the following holidays are celebrated:  New
         Year's Day,  Martin Luther King, Jr. Day (the third Monday in January),
         Presidents' Day (the third Monday in February),  Good Friday,  Memorial
         Day (the last Monday in May),  July 4th, Labor Day (the first Monday in
         September),  Thanksgiving  Day (the fourth  Thursday in  November)  and
         Christmas Day. Either or both of these Exchanges may close early on the
         business  day before  each of these  holidays.  Either or both of these
         Exchanges  also may close early on the day after  Thanksgiving  Day and
         the day before Christmas holiday.

Dividends and Distributions

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

Tax Consequences

         A ProFund  does not  ordinarily  pay income  tax on its net  investment
         income (which includes  short-term capital gains) and net capital gains
         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  gains  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:
         . 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  gain  of the  ProFund,  not on how  long  an
         investor has owned shares of the ProFund.
         .  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.
         . 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:
         .  receiving  and  processing  shareholder  orders,  o  performing  the
         accounting for the shareholder's account,
         . maintaining retirement plan accounts,
         .  answering   questions,   giving  investment   advice,  and  handling
         correspondence for individual accounts,
         . acting as the sole shareholder of record for individual shareholders,
         . issuing shareholder reports and transaction confirmations,
         . executing daily investment "sweep" functions, and
         .  providing  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.

         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 the ProFunds directly by phone

           your ProFunds account number

           Confirmation  number:  The  confirmation  number  given to you by the
           ProFunds representative

         Instructions,  written or  telephonic,  given to the  ProFunds for wire
         transfer  requests do not  constitute  a purchase  order until the wire
         transfer has been received by the ProFunds. The ProFunds are not liable
         for any loss incurred due to a wire transfer not having been received.

         Please note that your bank may charge a fee to send or receive wires.

         Please keep in mind when purchasing shares:
         . The minimum subsequent purchase amount is $100.
         . The  ProFunds  price  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.
         . A wire order is  considered in good order only if (i) you have called
         the ProFunds under the procedures described above and (ii) the ProFunds
         receive and accept your wire. The ProFunds can only accept wires during
         the times they process wires:  between 8:00 a.m. and 3:30 p.m., Eastern
         time for all the ProFunds.  Wires  received  after the  ProFunds'  wire
         processing  times  will be  processed  the next  business  day and will
         receive  that day's share price.  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.
         . 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.  The ProFunds (or their  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.
         .   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 a ProFund shares.

Exchanges

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

         The ProFunds accept exchange orders either by phone or in writing.  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.  The ProFunds can only accept
         exchange  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.  The ProFunds may not receive or
         accept  orders at any other  time.  If the  primary  exchange or market
         (generally,  the  CME) 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.
<PAGE>

         Please keep in mind when exchanging shares:
         . An exchange is actually a redemption  (sale) of shares of one ProFund
         and purchase of shares of another ProFund.
         . The  minimum  exchange  for  self-directed  accounts is $1,000 or, if
         less, for the account's entire current value. o You may exchange,  on a
         regular basis, shares of the Money Market ProFund (described in another
         prospectus) for shares of other ProFunds through an Automatic  Exchange
         Plan. For more information on this option,  please call the ProFunds at
         888-776-3637.
         . 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.

Redeeming ProFund Shares

         You can redeem all or part of your shares at the price next  determined
         after we receive  your  request.  The ProFunds  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.  The  ProFunds  may not receive or accept
         orders at any other time. 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.

         Written Redemptions
         To redeem all or part of your shares in writing,  your request needs to
         include the following information:
         . the name of the ProFund(s),
         . the account number(s),
         . the amount of money or number of shares being redeemed,
         . the name(s) of the account owners,
         . the signature(s) of all registered account owners, and
         . 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 the 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:
         . Your account  registration  or address has changed within the last 30
         calendar days.
         . The check is being mailed to a different address than the one on your
         account.
         . The check or wire is being made  payable  to  someone  other than the
         account owner.
         . The  redemption  proceeds are being  transferred to an account with a
         different registration.
         . You wish to redeem more than $100,000.
         . You are adding or changing wire instructions on your account.
         . Other unusual  situations  as  determined  by the ProFunds'  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.
<PAGE>

         Please keep in mind when redeeming shares:
         . 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.
         . The ProFunds normally remit redemption  proceeds within seven days of
         completing your liquidation out of the relevant ProFund. For redemption
         of shares purchased by check or Automatic Investment,  the ProFunds may
         wait up to 15 days before  sending  redemption  proceeds to assure that
         the transfer agent has collected the purchase payment.
         . The 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.
         . 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.
         .  Involuntary  Redemptions:  The ProFunds  reserve the right to redeem
         involuntarily an investor's  account,  including a retirement  account,
         which falls below the applicable  minimum  investment in total value in
         the  ProFunds  due to  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.

         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,  as  appropriate,  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 the ProFunds' investors.

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

         . It may be difficult to reach the 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.
         . 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.

Investment Advisor

         ProFund Advisors LLC
         ProFund  Advisors LLC,  located at 7900  Wisconsin  Avenue,  Suite 300,
         Bethesda,  Maryland 20814,  serves as the investment  advisor to all of
         the ProFunds and provides  investment  advice and management  services.
         ProFund Advisors oversees the investment and reinvestment of the assets
         in each  ProFund.  It receives fees equal to 0.75% of the average daily
         net assets of each of the UltraSmall-Cap  ProFund and the Ultra Mid-Cap
         ProFund  and 0.90% of the  average  daily net assets of the  UltraJapan
         ProFund. ProFund Advisors bears the costs of advisory services.

         Michael  L.  Sapir,  Chairman  and Chief  Executive  Officer of ProFund
         Advisors LLC, served as senior vice president of Padco Advisors,  Inc.,
         which advised Rydex(R) Funds. In addition,  Mr. Sapir practiced law for
         over 13 years,  most  recently as a partner in a  Washington-based  law
         firm. As an attorney,  Mr. Sapir advised and  represented  mutual funds
         and other  financial  institutions.  He holds  degrees from  Georgetown
         University Law Center (J.D.) and University of Miami (M.B.A. and B.A.).

         Louis  M.  Mayberg,  President  of  ProFund  Advisors  LLC,  co-founded
         National  Capital  Companies,  L.L.C.,  an investment bank in 1986, and
         manages its hedge fund. He holds a Bachelor of Business  Administration
         degree with a major in Finance from George Washington University.

         William E. Seale,  Ph.D.,  Director of Portfolio  for ProFund  Advisors
         LLC,  has more than 29 years of  experience  in the  commodity  futures
         markets. His background includes a five-year  presidential  appointment

         earned his degrees at University  of Kentucky.  Dr. Seale also holds an
         appointment as Professor of Finance at George Washington University.

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

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.  Each  ProFund  pays a fee of 0.15% of its
         average daily net assets for these services.

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

         The  ProFunds  have been  assured  that their  service  providers  have
         developed and implemented clearly defined and documented plans intended
         to minimize  risks to services  critical  to the  ProFunds'  operations
         associated with Year 2000 issues.  The service providers  likewise have
         sought  assurances  from their  respective  vendors and suppliers  that
         these entities have addressed any Year 2000 issues.

         In the event that any systems  upon which the  ProFunds  depend are not
         Year 2000 ready, 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 have not been
         completed.  The ProFunds will continue to closely monitor  developments
         relating to this issue.

                        7900 WISCONSIN AVENUE, SUITE 300

     This  Statement of  Additional  Information  describes  the  UltraSmall-Cap
ProFund, the UltraMid-Cap ProFund, and the UltraJapan ProFund (collectively, the
"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.  Each 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.

     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 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 investment
objectives of the ProFunds will be achieved.

     This Statement of Additional Information is not a prospectus.  It should be
read  in  conjunction  with  the  ProFunds'  Prospectus,  dated  [ ],  2000,  as
supplemented from time to time, which  incorporates this Statement of Additional
Information  by reference.  Words or phrases used in the Statement of Additional
Information  without definition have the same meaning as ascribed to them in the
Prospectus. A copy of the Prospectus is available,  without charge, upon request
to the address above or by telephoning at the telephone numbers above.

        The date of this Statement of Additional Information is [ ], 2000.

                                    PROFUNDS

     ProFunds (the "Trust") is an open-end management  investment  company,  and
currently  comprises  twenty-three  separate  series.  Three of the  series  are
discussed  herein.  All of  the  ProFunds  are  classified  as  non-diversified,
although they currently intend to operate in a diversified manner.

                       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.

     Certain  investment  restrictions of a ProFund  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
Investment  Company  Act of  1940,  as  amended  (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 Trust without
the approval of shareholders.

     A ProFund may consider changing its benchmark if, for example,  the current
benchmark  becomes  unavailable,  the ProFund believes 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  ProFunds   investment   results  to  correspond
sufficiently to its current benchmark.  If believed  appropriate,  a ProFund may
specify a benchmark for itself 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 ProFund Advisors
LLC (the "Advisor"),  the ProFunds'  investment adviser, in seeking to correlate
with the respective  benchmarks.  Rather, the Advisor primarily uses statistical
and  quantitative  analysis to determine  the  investments  a 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 ProFunds and the  performance of its  benchmark),  certain  factors
will  tend to  cause a  ProFunds'  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 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 ProFunds.  The ProFunds are free to
reduce  or  eliminate  the  ProFunds'  activity  in any of those  areas  without
changing the ProFunds  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 its objective.



<PAGE>




ULTRASMALL-CAP PROFUND

     The investment objective of the UltraSmall-Cap  ProFund is to provide daily
investment  results  that  correspond  to twice  (200%) the  performance  of the
Russell 2000(R) Index.

     The  UltraSmall-Cap  ProFund  does not intend to hold the 2,000  securities
included in the Russell  2000(R)  Index.  Instead,  the  UltraSmall-Cap  ProFund
intends to engage in  transactions in equities,  stock index futures  contracts,
options on stock index futures  contracts,  and options on securities  and stock
indexes.  As a nonfundamental  policy, the  UltraSmall-Cap  ProFund will invest,
under  normal  conditions,  at least 65% of its total  assets in the  securities
comprising  the  Russell  2000(R)  Index and  instruments  with  values that are
representative of such securities,  such as futures and option contracts on such
securities or such index.

     The Russell  2000(R) Index is a  capitalization-weighted  index of domestic
equities  traded on the NYSE, AMEX and NASDAQ.  The index  represents the bottom
2,000   companies   of  the  3,000  U.S.   stocks   with  the   largest   market
capitalizations.  As of June 30, 1999, the market  capitalization of these 2,000
companies  represented about 8% of the total market  capitalization of the 3,000
companies.  Companies whose stock comprises the Russell 2000(R) Index often have
limited  product  lines,  or relatively  new products or services,  and may lack
established markets, depth of experienced management, or financial resources and
the  ability to generate  funds.  The  securities  of these  companies  may have
limited  marketability  and may be more  volatile  in price than  securities  of
larger  capitalized  or more  well-known  companies.  Among the  reasons for the
greater  price  volatility  of  securities  of  smaller  companies  whose  stock
comprises  the Russell  2000(R) Index are the less certain  growth  prospects of
smaller firms, the lower degree of liquidity in the markets for such securities,
and the greater  sensitivity  of smaller  capitalization  companies  to changing
economic conditions than larger capitalization  companies.  Conversely,  because
many of these  securities may be overlooked by investors and  undervalued in the
marketplace, there is potential for significant capital appreciation.

ULTRAMID-CAP PROFUND

     The investment  objective of the  UltraMid-Cap  ProFund is to provide daily
investment  results that  correspond to twice (200%) the  performance of the S&P
MidCap 400 Index(R).

     The  UltraMid-Cap  ProFund  does  not  intend  to hold  the 400  securities
included in the S&P Mid-Cap 400  Index(R).  Instead,  the  UltraMid-Cap  ProFund
intends to engage in  transactions in equities,  stock index futures  contracts,
options on stock index futures  contracts,  and options on securities  and stock
indexes. As a nonfundamental policy, the UltraMid-Cap ProFund will invest, under
normal conditions, at least 65% of its total assets in the securities comprising
the S&P Mid-Cap 400 Index(R) and instruments with values that are representative
of such  securities,  such as futures and option contracts on such securities or
such index.

     The S&P MidCap 400 Index(R) is a widely used measure of medium  capitalized
U.S.  company stock  performance.  It consists of the common stocks of 400 major
corporations  selected  for their size and the  frequency  and ease 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 securities of medium
capitalization  companies,  while typically not as volatile as the securities of
small capitalization  companies,  may be more volatile than securities of larger
or more well-known companies.

ULTRAJAPAN PROFUND

     The  investment  objective of the  UltraJapan  ProFund is to provide  daily
investment results that correspond to twice (200%) the performance of the Nikkei
225 Stock Average.
<PAGE>

     The UltraJapan ProFund does not intend to hold the 225 securities  included
in the Nikkei 225 Stock  Average.  Instead,  the UltraJapan  ProFund  intends to
engage in transactions in equities,  stock index futures  contracts,  options on
stock index futures contracts, and options on securities and stock indexes. As a
nonfundamental   policy,  the  UltraJapan  ProFund  will  invest,  under  normal
conditions,  at least 65% of its total assets in the  securities  comprising the
Nikkei 225 Stock Average and instruments with values that are  representative of
such securities, such as futures and option contracts on such securities or such
index.

     The  Nikkei  225 Stock  Average  is a  price-weighted  index of 225  large,
actively traded Japanese stocks traded on the Tokyo Stock Exchange. The index is
computed and distributed by the Nihon Keizai Shimbun ("NKS")

     Investing in foreign companies or financial instruments by this ProFund 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 this ProFund will invest directly
or indirectly,  in foreign markets, it will be subject to certain of the market,
economic  and  political   risks  prevalent  in  these  foreign   markets,   and
particularly the Japanese 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 this 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.

     By investing in American Depository  Receipts  ("ADRs") under normal market
conditions,  the UltraJapan ProFund may reduce some of the risks of investing in
foreign securities.  ADRs are denominated in the U.S. Dollar,  which reduces the
risk of currency  fluctuations during the settlement period for either purchases
or sales.  Further, the information available for ADRs is subject to accounting,
auditing and financial reporting standards of the domestic market or exchange on
which they are traded,  which  standards are more uniform and more exacting than
those to  which  many  foreign  issuers  may be  subject.  However,  ADRs do not
eliminate  all the risk  inherent  in  investing  in the  securities  of foreign
issuers.

FUTURES CONTRACTS AND RELATED OPTIONS

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

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

     Whether a ProFund realizes a gain or loss from futures  activities  depends
generally  upon  movements  in  the  underlying  commodity.  The  extent  of the
ProFund's  loss from an unhedged  short  position in futures  contracts  or from
writing options on futures contracts is potentially unlimited.  The ProFunds may
engage in related closing purchase or sale  transactions with respect to options
on  futures  contracts  by  buying  an  option  of the same  series as an option
previously  written by a ProFund,  or selling an option of the same series as an
option  previously   purchased  by  a  ProFund.  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 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  promulgated  by the  Commodity
Futures Trading Commission (the "CFTC Regulations") under the Commodity Exchange
Act 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- bona fide
hedging  purposes to the extent that the  aggregate  initial  margins and option
premiums  required to  establish  such non- bona fide  hedging  positions do not
exceed 5% of the liquidation value of the ProFund's portfolio. In the case of an
option on  futures  contracts  that is  "in-the-money"  at the time of  purchase
(i.e.,  the amount by which the  exercise  price of the put option  exceeds  the
current  market  value of the  underlying  security  or the  amount by which the
current  market value of the underlying  security  exceeds the exercise price of
the call option), the in-the-money amount may be excluded in calculating this 5%
limitation.

     The ProFunds will cover their positions when they write a futures  contract
or option on a futures  contract.  A ProFund may "cover" its long  position in a
futures  contract by purchasing a put option on the same futures contract with a
strike price (i.e.,  an exercise  price) as high or higher than the price of the
futures  contract,  or, if the strike price of the put is less than the price of
the futures contract,  the ProFund will maintain in a segregated account cash or
liquid  instruments equal in value to the difference between the strike price of
the put and the price of the futures contract. 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  futures  contract.  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.
<PAGE>

     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 may  purchase  and write  options on stock  indexes to create
investment  exposure  consistent with their investment  objectives,  to 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 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  their  investment  objectives.
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 15%
limitation on investment in illiquid  securities by the ProFunds.  See "Illiquid
Securities."
<PAGE>

     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

     Each ProFund may buy and write (sell) options on securities for the purpose
of realizing its investment  objectives.  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.
<PAGE>

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

SWAP AGREEMENTS

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

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

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

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

     Swap agreements  typically are settled on a net basis, which means that the
two payment streams are netted out, with the ProFund receiving or paying, as the
case may be, only the net amount of the two  payments.  Payments  may be made at
the  conclusion  of a swap  agreement  or  periodically  during  its term.  Swap
agreements do not involve the delivery of securities or other underlying assets.
Accordingly,  the risk of loss with respect to swap agreements is limited to the
net amount of payments that a ProFund is contractually obligated to make. If the
other party to a swap agreement  defaults,  a ProFund's risk of loss consists of
the net amount of  payments  that such  ProFund  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
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 ProFund 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.

AMERICAN DEPOSITORY RECEIPTS

     For many foreign securities, U.S. Dollar denominated ADRs, which are traded
in the United  States on exchanges or  over-the-counter,  are issued by domestic
banks.  ADRs  represent  the right to  receive  securities  of  foreign  issuers
deposited in a domestic bank or a correspondent  bank. ADRs do not eliminate all
the risk inherent in investing in the securities of foreign issuers. However, by
investing in ADRs rather than directly in foreign issuers' stock, the UltraJapan
ProFund  can avoid  currency  risks  during  the  settlement  period  for either
purchase or sales.

     In general,  there is a large,  liquid market in the United States for many
ADRs. The information available for ADRs is subject to the accounting,  auditing
and financial  reporting  standards of the domestic  market or exchange on which
they are traded,  which  standards are more uniform and more exacting than those
to which many foreign  issuers may be subject.  Certain  ADRs,  typically  those
denominated  as  unsponsored,  require the  holders  thereof to bear most of the
costs of such  facilities,  while issuers of sponsored  facilities  normally pay
more of the costs thereof.  The depository of an unsponsored facility frequently
is under no obligation to distribute  shareholder  communications  received from
the issuer of the  deposited  securities or to pass through the voting rights to
facility  holders  with  respect  to  the  deposited  securities,   whereas  the
depository   of  a  sponsored   facility   typically   distributes   shareholder
communications and passes through the voting rights.

     The UltraJapan  ProFund may invest in both sponsored and unsponsored  ADRs.
Unsponsored   ADRs  programs  are  organized   independently   and  without  the
cooperation of the issuer of the  underlying  securities.  As result,  available
information concerning the issuers may not be as current for sponsored ADRs, and
the prices of unsponsored  depository receipts may be more volatile than if such
instruments were sponsored by the issuer.
<PAGE>

U.S. GOVERNMENT SECURITIES

     Each ProFund also may invest in U.S.  government  securities  in pursuit of
its  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  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. 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% of its  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,  liquidity,  investment,  regulatory, or other considerations so
warrant.
<PAGE>

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  ProFunds  may use  reverse  repurchase  agreements  as  part of  their
investment strategies.  Reverse repurchase agreements involve sales by a ProFund
of portfolio assets  concurrently with an agreement by the ProFund to repurchase
the same assets at a later date at a fixed price. Generally,  the effect of such
a  transaction  is that the ProFund 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 will be able to keep the interest income associated
with those portfolio securities.  Such transactions are advantageous only if the
interest cost to the ProFund 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  ProFunds  intend to use the
reverse repurchase  technique only when it will be to the ProFund's advantage to
do so. The ProFund will  establish a segregated  account with its custodian bank
in which the ProFund will maintain cash or liquid  instruments equal in value to
the ProFund's obligations in respect of reverse repurchase agreements.

BORROWING

     The ProFunds may borrow money for cash  management  purposes or  investment
purposes.   Each  of  the  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 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.
<PAGE>

LENDING OF PORTFOLIO SECURITIES

     Each of the ProFunds 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 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 any income accruing thereon,  and the ProFund may invest the
cash collateral in portfolio  securities,  thereby earning  additional income. A
ProFund  will not lend  more than 33 1/3% of the  value of the  ProFund's  total
assets.  Loans would be subject to  termination  by the lending  ProFund 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.  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  may  pay  reasonable   finders,   borrowers,
administrative, and custodial fees in connection with a loan.

WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES

     Each 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 ProFund
will not purchase securities on a when-issued or delayed-delivery basis if, as a
result,  more than 15% of the ProFund's net assets would be so invested.  At the
time of delivery of the  securities,  the value of the securities may be more or
less than the purchase price.

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

INVESTMENTS IN OTHER INVESTMENT COMPANIES

     The ProFunds may invest in the securities of other investment  companies to
the extent that such an investment  would be consistent with the requirements of
the 1940 Act. If a ProFund  invests in, and, thus, is a shareholder  of, another
investment  company,  the  ProFund's   shareholders  will  indirectly  bear  the
ProFund's  proportionate  share  of the  fees and  expenses  paid by such  other
investment company,  including advisory fees, in addition to both the management
fees payable directly by the ProFund to the ProFund's own investment adviser and
the other  expenses  that the  ProFund  bears  directly in  connection  with the
ProFund's own operations.

ILLIQUID SECURITIES

     While none of the ProFunds  anticipates  doing so, each of the ProFunds 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% of the  ProFund'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 may not be able to sell illiquid
securities when the Advisor  considers it desirable to do so or may have to sell
such  securities  at a price that is lower than the price that could be obtained
if the securities were more liquid. In addition, the sale of illiquid securities
also may require more time and may result in higher  dealer  discounts and other
selling  expenses  than  does the  sale of  securities  that  are not  illiquid.
Illiquid   securities   also  may  be  more   difficult  to  value  due  to  the
unavailability   of  reliable  market   quotations  for  such  securities,   and
investments  in  illiquid  securities  may have an  adverse  impact on net asset
value.
<PAGE>

     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. 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 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  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.  Each ProFund  expects to typically hold most of
its 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,  the ProFunds expect 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.
<PAGE>

     TRACKING ERROR.  While the 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) a
ProFund  share  prices  being  rounded to the nearest  cent;  (7) changes to the
benchmark index that are not disseminated in advance;  (8) the need to conform a
ProFund's portfolio holdings to comply with investment  restrictions or policies
or regulatory or tax law requirements,  and (9) early and unanticipated closings
of the  markets  on which the  holdings  of a ProFund  trade,  resulting  in the
inability of the ProFund to execute  intended  portfolio  transactions.  While a
close  correlation of any ProFund to its benchmark may be achieved on any single
trading day, over time the cumulative percentage increase or decrease in the net
asset  value of the  shares  of a ProFund  may  diverge  significantly  from the
cumulative percentage decrease or increase in the benchmark due to a compounding
effect.

     LEVERAGE.  Each ProFund intends to 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 ProFund during favorable market conditions and the risk of
magnified losses during adverse market conditions.  Leverage should cause higher
volatility  of the net asset  values of these  ProFund's  shares.  Leverage  may
involve the creation of a liability  that does not entail any interest  costs or
the creation of a liability  that  requires  the ProFund to pay  interest  which
would  decrease the ProFund's  total return to  shareholders.  If 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 ProFund is a  "non-diversified"  series. Each
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 ProFund that are less restrictive
than the requirements applicable to the "diversified" investment companies under
the 1940 Act.

                             INVESTMENT RESTRICTIONS

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

     A 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  or
repurchase agreements with respect thereto).

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

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

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

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

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

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

                        DETERMINATION OF NET ASSET VALUE

     The net asset values of the shares of the ProFunds 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.

     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  shares  of a  ProFund  serves as the basis for the
purchase and redemption  price of each class of shares.  The net asset value per
share of a ProFund is  calculated  by dividing the market value of the ProFund's
assets,  less all  liabilities  attributed  to the  ProFund,  by the  number  of
outstanding  shares  of the  ProFund.  If  market  quotations  are  not  readily
available,  a security will be valued at fair value by the Trustees of the Trust
or by the Advisor using methods  established  or ratified by the Trustees of the
Trust.
<PAGE>

     The  securities in the portfolio of a ProFund,  except as otherwise  noted,
that are  listed or traded on a stock  exchange,  are valued on the basis of the
last sale on that day or, lacking any sales, at a price that is the mean between
the  closing  bid and asked  prices.  Other  securities  that are  traded on the
over-the-counter  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.

     Futures  contracts  maintained  by  ProFunds  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  established  futures
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
positions  traded on such  exchange  and held by a ProFund will be valued on the
basis of the day's settlement prices on the futures exchange or fair value.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

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

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

     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.
<PAGE>

     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.

securities  laws.  The  Administrator  also  maintains the  shareholder  account
records for the ProFunds, distributes dividends and distributions payable by the
ProFunds,  and  produces  statements  with  respect to account  activity for the
ProFunds and their  shareholders.  The Administrator  pays all fees and expenses
that are directly related to the services  provided by the  Administrator to the
ProFunds;  each ProFund  reimburses the  Administrator for all fees and expenses
incurred by the Administrator which are not directly related to the services the
Administrator provides to the ProFunds under the service agreement.

     For its  services as  Administrator,  each ProFund pays BISYS an annual fee
equal to .05% of average daily net assets. BISYS Funds Services,  Inc. ("BFSI"),
an affiliate of BISYS,  acts as transfer agent and fund accounting agent for the
ProFunds,  for which it receives  additional  fees.  Additionally,  ProFunds and
BISYS and BFSI have entered into an Omnibus Fee Agreement in which the amount of
compensation  due and payable to BISYS shall be the greater of (i) the aggregate
fee amount due and payable for  services  pursuant to the  Administration,  Fund
Accounting and Transfer Agency Agreements and (ii) the minimum  relationship fee
described  as specific  dollar  amounts  payable  over a period of ten  calendar
quarters.  The  address  for BISYS and BFSI is 3435  Stelzer  Road,  Suite 1000,
Columbus, Ohio 43219.
<PAGE>

     The Advisor, pursuant to a separate Management Services Agreement, performs
certain  client  support  and  other  administrative  services  on behalf of the
ProFunds. For these services,  each ProFund will pay to the Advisor a fee at the
annual rate of .15% of its average daily net assets for all ProFunds.

     UMB Bank, N.A. acts as custodian to the ProFunds.  UMB Bank, N.A.'s address
is 928 Grand Avenue, Kansas City, Missouri.

INDEPENDENT ACCOUNTANTS

     PricewaterhouseCoopers  LLP serves as independent auditors to the ProFunds.
PricewaterhouseCoopers  LLP provides audit services,  tax return preparation and
assistance   and   consultation   in   connection   with  certain  SEC  filings.
PricewaterhouseCoopers  LLP is located at 100 East Broad Street,  Columbus, Ohio
43215.

LEGAL COUNSEL

     Dechert  Price & Rhoads  serves as  counsel  to the  ProFunds.  The  firm's
address is 1775 Eye Street, N.W., Washington, DC 20006-2401.

DISTRIBUTOR

     Concord  Financial Group,  Inc., 3435 Stelzer Road,  Columbus,  Ohio 43219,
serves as the distributor and principal  underwriter of the ProFunds'  shares in
all fifty states and the District of Columbia.  Concord  Financial  Group,  Inc.
receives no compensation from the ProFunds for serving as distributor.

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  Service
Class shares  attributable to or held in the name of the investment advisers and
other  authorized  institutions  that sell  Service  Class  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  Class 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 Class 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,  have voted to adopt the Plan and Shareholder Services Agreements at
a meeting  called  for the  purposes  of  voting  on such  Plan and  Shareholder
Services Agreements. 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. The Plan may be terminated at any time by a majority
of the Trustees as described above or by a vote of a majority of the outstanding
Service  Class  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 Class 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 Class shares of such ProFunds.  In the Trustees' quarterly review of the
Plan and  Shareholder  Services  Agreements,  they will consider their continued
appropriateness and the level of compensation provided therein.
<PAGE>

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

                               COSTS AND EXPENSES

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

          ORGANIZATION AND DESCRIPTION OF SHARES OF BENEFICIAL INTEREST

     ProFunds 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 twenty-three separately managed series, three of which are described
herein. Other series may be added in the future. Each ProFund offers two classes
of share: the Service Class shares and the Investor Class shares.

     All shares of the ProFunds are freely transferable. The Trust shares do not
have preemptive rights or cumulative voting rights,  and none of the shares have
any preference to conversion,  exchange,  dividends,  retirements,  liquidation,
redemption,  or any other feature. Trust shares have equal voting rights, except
that, in a matter  affecting only 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 of such Trustees.  If requested by  shareholders of at least
10% of the  outstanding  shares of the  Trust,  the Trust will call a meeting of
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  Trust  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  shareholder  held  personally  liable for the obligations of the
Trust. The risk of a Trust  shareholder  incurring  financial loss on account of
shareholder  liability  is limited to  circumstances  in which the Trust  itself
would  not be able  to  meet  the  Trust's  obligations.  This  risk  should  be
considered remote.
<PAGE>

                                    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.

     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 the 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).
<PAGE>

     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 a 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."

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).
<PAGE>

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  straddles  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.

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.
<PAGE>

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,  the  ProFunds  will  change the  distribution
option so that all  distributions  are  automatically  reinvested  in additional
shares. The 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.
<PAGE>

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 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.

     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.

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  Deutsche
Aktienindex,  all of which are unmanaged market indicators. Such comparisons can
be useful  measures  of the quality of a ProFund's  investment  performance.  In
particular,  performance  information  for  the  UltraSmall-Cap  ProFund  may be
compared to various unmanaged indexes, including, but not limited to its current
benchmark,   the  Russell  2000(R)  Index;   performance   information  for  the
UltraMid-Cap  ProFund may be compared to various unmanaged  indexes,  including,
but not limited to, its current benchmark,  the S&P MidCap 400 Index(R); and the
performance  information  for the UltraJapan  ProFund may be compared to various
unmanaged indexes,  including,  but not limited to, its current  benchmark,  the
Nikkei 225 Stock Average.

     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 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.

     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.  However,  because
the  ProFunds  have no  history  of  investment  operations,  they  have not yet
prepared any shareholder reports.

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,
the Advisor also makes its own evaluation of these securities, subject to review
by the Board of Trustees.  A  description  of the ratings used herein and in the

                                   APPENDIX B

                        DESCRIPTION OF SECURITIES RATINGS

DESCRIPTION OF S&P'S CORPORATE RATINGS:

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

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

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

DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS:

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

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

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

DESCRIPTION OF FITCH INVESTORS SERVICE'S CORPORATE BOND RATINGS:

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

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


DESCRIPTION OF DUFF & PHELPS' CORPORATE BOND RATINGS:

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

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

DESCRIPTION OF S&P'S MUNICIPAL BOND RATINGS:

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

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

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

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

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

DESCRIPTION OF MOODY'S MUNICIPAL BOND RATINGS:

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

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

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

DESCRIPTION OF S&P'S MUNICIPAL NOTE RATINGS:

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

DESCRIPTION OF MOODY'S MUNICIPAL NOTE RATINGS:

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

DESCRIPTION OF S&P COMMERCIAL PAPER RATINGS:

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

DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS:

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

DESCRIPTION OF FITCH INVESTORS SERVICE'S COMMERCIAL PAPER RATINGS:

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

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

DESCRIPTION OF DUFF & PHELPS' COMMERCIAL PAPER RATINGS:

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

     Duff 1-Very high certainty of timely +.

DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS:

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

DESCRIPTION OF FITCH INVESTORS SERVICE'S COMMERCIAL PAPER RATINGS:

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

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

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

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

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

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

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

     C-Obligations which are currently in default.

     Notes: "+" or "-".

DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS:

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

DESCRIPTION OF FITCH INVESTORS SERVICE'S COMMERCIAL PAPER RATINGS:

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

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

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

     C-Obligations  for which there is an  inadequate  capacity to ensure timely
     repayment.  D-Obligations  which  have a high risk of  default or which are
     currently in default

DESCRIPTION OF THOMSON BANK WATCH SHORT-TERM RATINGS:

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

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

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

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

DESCRIPTION OF THOMSON BANKWATCH LONG-TERM RATINGS:

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

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

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

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

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

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

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

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

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

     D-Default

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

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

ITEM 24. Persons Controlled By or Under Common Control With Registrant.
         None.

ITEM 25. Indemnification

         The  Registrant  is  organized  as a  Delaware  business  trust  and is
         operated pursuant to a Declaration of Trust, dated as of April 17, 1997
         (the "Declaration of Trust"),  that permits the Registrant to indemnify
         its  trustees   and  officers   under   certain   circumstances.   Such
         indemnification,  however, is subject to the limitations imposed by the
         Securities Act of 1933, as amended,  and the Investment  Company Act of
         1940, as amended.  The Declaration of Trust of the Registrant  provides
         that  officers  and trustees of the Trust shall be  indemnified  by the
         Trust  against  liabilities  and  expenses  of defense  in  proceedings
         against  them by reason of the fact that they each  serve as an officer
         or trustee  of the Trust or as an officer or trustee of another  entity
         at the request of the entity.  This  indemnification  is subject to the
         following conditions:

         (a)      no trustee or officer of the Trust is indemnified  against any
                  liability to the Trust or its security  holders  which was the
                  result of any willful misconduct, bad faith, gross negligence,
                  or reckless disregard of his duties;

         (b)      officers  and trustees of the Trust are  indemnified  only for
                  actions  taken in good faith which the  officers  and trustees
                  believed  were in or not opposed to the best  interests of the
                  Trust; and

         (c)      expenses  of any suit or  proceeding  will be paid in  advance
                  only if the persons who will benefit by such advance undertake
                  to repay the expenses  unless it  subsequently  is  determined
                  that such persons are entitled to indemnification.


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

ITEM 26. Business and Other Connections  of Investment  Advisor

         ProFund  Advisors  LLC (the  "Advisor"),  a limited  liability  company

         Trust  which  serves  as  investment  adviser  to the  Cash  Management
         Portfolio  and each  director,  officer or partner of Bankers Trust are

            Establishment and Designation of Three Additional Series

The undersigned, being all of the Trustees of ProFunds (the "Trust"), a Delaware
business  trust,  acting  pursuant to Section  4.9.2 of the Amended and Restated
Declaration of Trust dated October 28, 1997 (the "Declaration of Trust"), hereby
divide the shares of beneficial interest ("Shares") of the Trust into additional
separate  series  (the  "Fund"),  of two  classes  known as the  "Investor"  and
"Service"  class  (each of  which  bears  the  expenses  attributable  to it and
otherwise has the relative  rights and  preferences set forth in the Declaration
of Trust),  the Funds hereby created  having the following  special and relative
rights:

         1.       The Funds shall be designated as follows:

                  UltraSmall-Cap ProFund
                  UltraMid-Cap ProFund
                  UltraJapan ProFund

         2.  Each  Fund  shall be  authorized  to  invest  in cash,  securities,
instruments  and  other  property  as from  time to time  described  in the then
current prospectus and registration  statement  materials for the Fund under the
Securities  Act of  1933.  Each  Share  of a Fund  shall  be  redeemable,  shall
represent a pro rata beneficial interest in the assets of the Fund, and shall be
entitled to receive its pro rata share of net assets allocable to such Shares of
the Fund upon  liquidation of the Fund, as provided in the Declaration of Trust.
The  proceeds  of sales of Shares of a Fund,  together  with any income and gain
thereon,  less any diminution or expenses thereof,  shall irrevocably  belong to
the Fund, unless otherwise required by law.

         3. Each Share of a Fund shall be  entitled  to one vote for each dollar
of value  invested  (or fraction  thereof in respect of a  fractional  Share) on
matters on which such Shares  shall be  entitled  to vote,  except to the extent
otherwise  required by the  Investment  Company Act of 1940 or when the Trustees
have  determined  that the matter affects only the interest of  Shareholders  of
certain series or classes, in which case only the Shareholders of such series or
classes  shall be entitled to vote  thereon.  Any matter shall be deemed to have
been effectively  acted upon with respect to a Fund if acted upon as provided in

Trust.

                  with the  organization and registration and public offering of
                  Shares of the Fund  shall be  amortized  for the Fund over the
                  lesser  of the  life  of the  Fund  or such  other  period  as
                  required by  applicable  law;  costs  incurred by the Trust on
                  behalf  of   pre-existing   Funds  in   connection   with  the
                  organization  and initial  registration and public offering of
                  Shares of those  Funds shall be  amortized  for the Funds over

         (b)      Liabilities,  expenses, costs, charges or reserves relating to
                  the distribution of, and other identified expenses that should
                  properly be allocated to, the Shares of a particular class may
                  be charged to and borne  solely by such class and the  bearing
                  of expenses  solely by a class of Shares may be  appropriately
                  reflected  and  cause  differences  in  the  net  asset  value
                  attributable  to and the dividend,  redemption and liquidation
                  rights of, the Shares of different classes.

         (c)      The  Trustees may from time to time in  particular  cases make
                  specific  allocations of assets or liabilities among the Funds
                  or classes,  and each  allocation  of  liabilities,  expenses,
                  costs,   charges  and  reserves  by  the  Trustees   shall  be
                  conclusive and binding upon the  Shareholders of all Funds and
                  classes for all purposes.

         5.  Shares of each class of a Fund may vary  between  themselves  as to
rights of redemption and conversion  rights,  as may be approved by the Trustees
and set out in the Fund's then-current prospectus.

         6. The Trustees  (including any successor Trustee) shall have the right
at any time and from time to time to reallocate assets and expenses or to change
the designation of any Fund now or hereafter  created or to otherwise change the
special and relative  rights of any such Fund,  provided  that such change shall
not adversely affect the rights of the Shareholders of such Fund.

                          INVESTMENT ADVISORY AGREEMENT

         AGREEMENT  made as of  June 4,  1999  by and  between  CASH  MANAGEMENT
PORTFOLIO,  a New York trust  (herein  called the  "Trust")  and  BANKERS  TRUST
COMPANY (herein called the "Investment Adviser").

         WHEREAS,  the Trust is registered as an open-end management  investment
company under the Investment Company Act of 1940;

         WHEREAS,  the Trust desires to retain the Investment  Adviser to render
investment  advisory and other  services to the Trust with respect to certain of
its  series of shares  of  beneficial  interests  as may  currently  exist or be
created in the future  (each,  a "Fund") as listed on Exhibit A hereto,  and the
Investment  Adviser  is  willing  to  so  render  such  services  on  the  terms
hereinafter set forth;

         NOW, THEREFORE, this Agreement

                              W I T N E S S E T H:

         In consideration of the promises and mutual covenants herein contained,
it is agreed between the parties hereto as follows:

         1. Appointment. The Trust hereby appoints the Investment Adviser to act
as investment  adviser to each Fund for the period and on the terms set forth in
this Agreement.  The Investment  Adviser accepts such  appointment and agrees to
render the services herein set forth for the compensation herein provided.

         2.  Management.  Subject to the supervision of the Board of Trustees of
the Trust, the Investment  Adviser will provide a continuous  investment program
for the Fund,  including  investment research and management with respect to all
securities,  investments,  cash and cash equivalents in the Fund. The Investment
Adviser will determine from time to time what  securities and other  investments
will be purchased,  retained or sold by each Fund. The  Investment  Adviser will
provide the services  rendered by it hereunder in accordance with the investment
objective(s)  and  policies  of each Fund as stated in the  Fund's  then-current
prospectus and statement of additional  information  (or the Fund's then current
registration  statement on Form N-1A as filed with the  Securities  and Exchange
Commission (the "SEC") and the then-current  offering  memorandum if the Fund is
not registered  under the  Securities Act of 1933, as amended ("1933 Act").  The
Investment Adviser further agrees that it:

                  (a) will conform with all applicable  rules and regulations of
the SEC (herein  called the "Rules") and with all  applicable  provisions of the
1933 Act; as amended, the Securities Exchange Act of 1934, as amended (the "1934
Act"), the Investment  Company Act of 1940, as amended (the "1940 Act"); and the
Investment  Advisers Act of 1940, as amended (the "Advisers  Act"), and will, in
addition,  conduct  its  activities  under this  Agreement  in  accordance  with
regulations of the Board of Governors of the Federal  Reserve System  pertaining
to the  investment  advisory  activities  of bank  holding  companies  and their
subsidiaries;
<PAGE>

                  (b)   will   place   orders   pursuant   to   its   investment
determinations  for each Fund either directly with the issuer or with any broker
or dealer  selected by it. In placing  orders  with  brokers  and  dealers,  the
Investment  Adviser will use its reasonable  best efforts to obtain the best net
price and the most favorable execution of its orders,  after taking into account
all  factors  it deems  relevant,  including  the  breadth  of the market in the
security,  the price of the  security,  the  financial  condition  and execution
capability of the broker or dealer, and the reasonableness of the commission, if
any, both for the specific  transaction  and on a continuing  basis.  Consistent
with this  obligation,  the Investment  Adviser may, to the extent  permitted by
law, purchase and sell portfolio  securities to and from brokers and dealers who
provide  brokerage and research services (within the meaning of Section 28(e) of
the 1934 Act) to or for the benefit of any fund and/or other accounts over which
the Investment Adviser or any of its affiliates exercises investment discretion.
Subject to the review of the Trust's  Board of  Trustees  from time to time with
respect to the extent and continuation of the policy,  the Investment Adviser is
authorized to pay to a broker or dealer who provides such brokerage and research
services a commission for effecting a securities  transaction which is in excess
of the amount of  commission  another  broker or dealer  would have  charged for
effecting that  transaction if the Investment  Adviser  determines in good faith
that such  commission  was  reasonable in relation to the value of the brokerage
and  research  services  provided by such  broker or dealer,  viewed in terms of
either  that  particular  transaction  or the  overall  responsibilities  of the
Investment  Adviser  with  respect  to the  accounts  as to which  it  exercises
investment discretion; and

                  (c) will  maintain  books  and  records  with  respect  to the
securities  transactions  of each Fund and will render to the  Trust's  Board of
Trustees such periodic and special reports as the Board may request.

         3. Services Not Exclusive. The investment advisory services rendered by
the  Investment  Adviser  hereunder  are  not to be  deemed  exclusive,  and the
Investment Adviser shall be free to render similar services to others so long as
its services under this Agreement are not impaired thereby.

         4. Books and Records. In compliance with the requirements of Rule 31a-3
of the Rules under the 1940 Act, the  Investment  Adviser hereby agrees that all
records  which it  maintains  for the  Trust are the  property  of the Trust and
further  agrees to  surrender  promptly  to the Trust any of such  records  upon
request of the Trust. The Investment  Adviser further agrees to preserve for the
periods  prescribed by Rule 31 a-2 under the 1940 Act the records required to be
maintained  by Rule 31 a-1  under  the 1940 Act and to  comply  in full with the
requirements  of Rule 204-2 under the Advisers Act pertaining to the maintenance
of books and records.

         5. Expenses.  During the term of this Agreement, the Investment Adviser
will pay all expenses  incurred by it in connection  with its  activities  under
this Agreement other than the cost of purchasing securities (including brokerage
commissions, if any) for the Fund.
<PAGE>

         6.  Compensation.  For the services  provided and the expenses  assumed
pursuant to this Agreement,  the Trust will pay the Investment Adviser,  and the
Investment  Adviser will accept as full  compensation  therefor a fee,  computed
daily and payable  monthly,  an amount  equal to the annual rate of 0.15% of the
Portfolio's average daily net assets.

         7.  Limitation of Liability of the Investment Adviser: Indemnification.

                  (a) The  Investment  Adviser shall not be liable for any error
of judgment or mistake of law or for any loss  suffered by a Fund in  connection
with the matters to which this Agreement relates, except a loss resulting from a
breach of  fiduciary  duty with  respect  to the  receipt  of  compensation  for
services  or a loss  resulting  from  willful  misfeasance,  bad  faith or gross
negligence  on the part of the  Investment  Adviser  in the  performance  of its
duties or from reckless disregard by it of its obligations and duties under this
Agreement;

                  (b) Subject to the  exceptions  and  limitations  contained in
Section 7(c) below:

                         (i) the Investment Adviser (hereinafter  referred to as
a "Covered  Person") shall be indemnified by the respective  Fund to the fullest
extent permitted by law, against  liability and against all expenses  reasonably
incurred or paid by him in connection with any claim, action, suit or proceeding
in which he becomes involved, as a party or otherwise, by virtue of his being or
having been the  Investment  Adviser of the Fund,  and against  amounts  paid or
incurred by him in the settlement thereof;

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

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

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

                         (ii) in the  event of a  settlement,  unless  there has
been a  determination  that  such  Covered  Person  did not  engage  in  willful
misfeasance,  bad faith,  gross  negligence or reckless  disregard of the duties
involved in the conduct of his office;
<PAGE>

                              (A) by the  court  or  other  body  approving  the
settlement; or

                              (B) by at least a majority of those  Trustees  who
are neither  Interested Persons of the Trust nor are parties to the matter based
upon a review of  readily  available  facts  (as  opposed  to a full  trial-type
inquiry); or

                              (C)  by  written  opinion  of  independent   legal
counsel  based upon a review of readily  available  facts (as  opposed to a full
trial-type  inquiry);  provided,  however,  that any  investor in a Fund may, by
appropriate legal proceedings,  challenge any such determination by the Trustees
or by independent counsel.

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

                  (e)  Expenses  in   connection   with  the   preparation   and
presentation  of a defense to any claim,  suit or  proceeding  of the  character
described in subsection (b) of this Section 7 may be paid by the Trust on behalf
of the respective Fund from time to time prior to final disposition thereto upon
receipt  of an  undertaking  by or on behalf of such  Covered  Person  that such
amount will be paid over by him to the Trust on behalf of the respective Fund if
it is ultimately  determined  that he is not entitled to  indemnification  under
this Section 7;  provided,  however,  that either (i) such Covered  Person shall
have provided  appropriate security for such undertaking or (ii) the Trust shall
be insured  against  losses arising out of any such advance  payments,  or (iii)
either a majority  of the  Trustees  who are neither  Interested  Persons of the
Trust nor  parties to the  matter,  or  independent  legal  counsel in a written
opinion,  shall have determined,  based upon a review of readily available facts
as opposed to a trial-type inquiry or full  investigation,  that there is reason
to believe that such Covered  Person will be entitled to  indemnification  under
this Section 7.

         8. Duration and Termination.  This Agreement shall be effective as to a
Fund  as of the  date  the  Fund  commences  investment  operations  after  this
Agreement  shall have been  approved  by the Board of Trustees of the Trust with
respect to that Fund and the Investor(s) in the Fund in the manner  contemplated
by Section 15 of the 1940 Act and, unless sooner  terminated as provided herein,
shall continue until the second  anniversary  of such date.  Thereafter,  if not
terminated,  this  Agreement  shall  continue  in  effect  as to such  Fund  for
successive periods of 12 months each,  provided such continuance is specifically
approved at least annually (a) by the vote of a majority of those members of the
Board  of  Trustees  of the  Trust  who are not  parties  to this  Agreement  or
Interested Persons of any such party, cast in person at a meeting called for the
purpose  of  voting  on  such  approval,  or (b) by Vote  of a  Majority  of the
Outstanding  Voting  Securities  of the  Trust;  provided,  however,  that  this
Agreement may be terminated by the Trust at any time, without the payment of any
penalty,  by the Board of  Trustees  of the Trust,  by Vote of a Majority of the
Outstanding  Voting  Securities of the Trust on 60 days'  written  notice to the
Investment  Adviser,  or by the Investment  Adviser as to the Trust at any time,
without  payment of any penalty,  on 90 days' written notice to the Trust.  This
Agreement will immediately  terminate in the event of its assignment (as used in
this  Agreement,  the  terms  "Vote  of a  Majority  of the  Outstanding  Voting
Securities,"  "Interested  Person" and "Assignment' shall have the same meanings
as such  terms have in the 1940 Act and the rules and  regulatory  constructions
thereunder.)
<PAGE>

         9. Amendment of this Agreement.  No material term of this Agreement may
be changed,  waived,  discharged or terminated orally, but only by an instrument
in writing signed by the party against which enforcement of the change,  waiver,
discharge or termination is sought,  and no amendment of a material term of this
Agreement shall be effective with respect to a Fund, until approved by Vote of a
Majority of the Outstanding Voting Securities of that Fund.

         transaction  was effected,  the trade date,  the  settlement  date, the
         identity  of  the   effecting   broker  or  dealer  and/or  such  other
         information, and in such manner, as may from time to time be reasonably
         requested by the Trust;

                  (b) maintain all applicable  books and records with respect to
         the securities transactions of the Portfolio. Specifically, but without
         limitation,  Advisor  agrees to maintain with respect to each Portfolio
         those records required to be maintained under Rule 31a-1(b)(1),  (b)(5)
         and  (b)(6)  under the 1940 Act with  respect to  transactions  in each
         Portfolio   including,   without  limitation,   records  which  reflect
         securities  purchased or sold in the  Portfolio,  showing for each such
         transaction,  the market on which the  transaction  was  effected,  the
         trade date,  the  settlement  date,  and the identity of the  executing
         broker or dealer.  Advisor will preserve such records in the manner and
         for the periods  prescribed  by Rule 31a-2 under the 1940 Act.  Advisor
         acknowledges  and agrees  that all such  records it  maintains  for the
         Trust are the property of the Trust and Advisor will surrender promptly
         to the Trust any such records upon the Trust's request;

                  (c) provide,  in a timely manner,  such  information as may be
         reasonably   requested  by  the  Trust  or  its  designated  agents  in
         connection  with,  among other things,  the daily  computation  of each
         Portfolio's  net  asset  value  and net  income,  preparation  of proxy
         statements  or  amendments  to the Trust's  registration  statement and
         monitoring  investments made in the Portfolio to ensure compliance with
         the various limitations on investments applicable to the Portfolio,  to
         ensure  that  the  Portfolio  will  continue  to  qualify  for  the tax
         treatment accorded to regulated investment companies under Subchapter M
         of the Internal  Revenue Code of 1986, as amended (the "Code"),  and to
         ensure  that the  Portfolios  that serve as the  investment  medium for
         variable  insurance  contracts  are  managed  in  conformity  with  the
         requirements  of  Section  817  of the  Code  and  Treasury  Regulatory
         subsection 1.817-5 thereunder (or any successor or amended provision);

                  (d)  render  regular  reports  to  the  Trust  concerning  the
         performance by Advisor of its responsibilities under this Agreement. In
         particular,  Advisor agrees that it will, at the reasonable  request of
         the Board of  Trustees,  attend  meetings  of the Board or its  validly
         constituted  committees  and will,  in addition,  make its officers and
         employees  available  to meet with the  officers  and  employees of the
         Trust at least quarterly and at other times upon reasonable  notice, to
         review the investments and investment programs of the Portfolio;

<PAGE>

                  (e)  maintain  its  policy  and  practice  of  conducting  its
         fiduciary functions independently. In making investment recommendations
         for the  Portfolios,  the Advisor's  personnel will not inquire or take
         into  consideration  whether the  issuers of  securities  proposed  for
         purchase or sale for the Trust's  account are  customers of the Advisor
         or of its affiliates.  In dealing with such customers,  the Advisor and
         its  affiliates  will not  inquire or take into  consideration  whether
         securities of those customers are held by the Trust; and

                  (f)  review  periodically  and  take  responsibility  for  the
         material accuracy and completeness of the information supplied by or at
         the  request of the  Advisor  for  inclusion  in  Trust's  registration
         statement under the 1940 Act and the Securities Act of 1933.

3.  PORTFOLIO TRANSACTIONS

         Advisor  shall be  responsible  for  selecting  members  of  securities
exchanges,  brokers and dealers  (herein after referred to as "brokers") for the
execution of purchase and sale  transactions  for the  Portfolios.  In executing
portfolio  transactions  and selecting  brokers or dealers,  if any, the Advisor
will use its best  efforts  to seek on behalf of a  Portfolio  the best  overall
terms  available.  In  assessing  the  best  overall  terms  available  for  any
transaction, the Advisor shall consider all factors it deems relevant, including
brokerage and research  services (as those terms are defined in Section 28(e) of
the  Securities  Exchange  Act of 1934)  provided to any  Portfolio of the Trust
and/or  other  accounts  over which the Advisor or an  affiliate  of the Advisor
exercises investment  discretion.  The Advisor may pay to a broker or dealer who
provides  such  brokerage  and research  services a commission  for  executing a
portfolio  transaction  which is in excess of the amount of  commission  another
broker or dealer would have charged for effecting that  transaction if, but only
if, the Advisor  determines in good faith that such commission was reasonable in
relation to the value of the  brokerage  and  research  services  provided.  The
Advisor will report to the Trustees  from time to time  regarding  its portfolio
execution and brokerage practices.

4.  EXPENSES AND COMPENSATION

         a)       Allocation of Expenses

                  The Advisor  shall,  at its expense,  employ or associate with
         itself such persons as it believes  appropriate to assist in performing
         its obligations under this Agreement and provide all advisory services,
         equipment,   facilities   and   personnel   necessary  to  perform  its
         obligations under this Agreement.


<PAGE>

                  The  Trust  shall  be  responsible  for all its  expenses  and
         liabilities,   including,  without  limitation,   compensation  of  its
         Trustees who are not affiliated with the Portfolios'  Administrator  or
         the Advisor or any of their  affiliates;  taxes and governmental  fees;
         interest  charges;   fees  and  expenses  of  the  Trust's  independent
         accountants and legal counsel;  trade association membership dues; fees
         and expenses of any custodian (including for keeping books and accounts
         and  calculating  the net  asset  value of  shares  of each  Portfolio,
         transfer agent,  registrar and dividend  disbursing agent of the Trust;
         expenses of issuing, selling, redeeming, registering and qualifying for
         sale the Trust's shares of beneficial  interest;  expenses of preparing
         and printing share certificates (if any),  prospectuses,  shareholders'
         reports,  notices, proxy statements and reports to regulatory agencies;
         the cost of office supplies; travel expenses of all officers,  trustees
         and  employees;  insurance  premiums;  brokerage and other  expenses of
         executing portfolio  transactions;  expenses of shareholders' meetings;
         organizational expenses; and extraordinary expenses.

         b)       Compensation

                  For its  services  under  this  Agreement,  Advisor  shall  be
         entitled to receive a fee calculated at the applicable  annual rate set
         forth on Schedule A hereto with respect to the average  daily net asset
         value of each Portfolio, which will be paid monthly. For the purpose of
         accruing  compensation,  the net asset value of the Portfolios  will be
         determined in the manner provided in the then-current Prospectus of the
         Trust.

         c)       Expense Limitations

                  Advisor  may waive all or a portion of its fees  provided  for
         hereunder  and  such  waiver  will be  treated  as a  reduction  in the
         purchase price of its services.  Advisor shall be  contractually  bound
         hereunder by the terms of any publicity announced waiver of its fee, or
         any  limitation  of the  Portfolio's  expenses,  as if such waiver were
         fully set forth herein.

5.  LIABILITY OF ADVISOR

         Neither the Advisor nor its officers,  directors,  employees, agents or
controlling person ("Associated  Person") of the Advisor shall be liable for any
error of  judgement  or mistake of law or for any loss  suffered by the Trust in
connection with the matters to which this Agreement relates  including,  without
limitation,  losses  that may be  sustained  in  connection  with the  purchase,
holding,  redemption  or sale of any security or other  investment  by the Trust
except a loss resulting from willful misfeasance,  bad faith or gross negligence
on the part of Advisor or such  Associated  Persons in the  performance of their
duties or from reckless disregard by them of their duties under this Agreement.

6. LIABILITY OF THE TRUST AND PORTFOLIOS

         It is  expressly  agreed that the  obligations  of the Trust  hereunder
shall not be binding upon any of the Trustees, shareholders, nominees, officers,
agents or  employees  of the  Trust  personally,  but shall  bind only the trust
property of the Trust as provided in the Declaration of Trust. The execution and
delivery of this Agreement have been authorized by the Trustees, and it has been
signed  by  an  officer  of  the  Trust,   acting  as  such,  and  neither  such
authorization  by such Trustees nor such  execution and delivery by such officer
shall be deemed to have been made by any of them  individually  or to impose any
liability on any of them  personally,  but shall bind only the trust property of
the Trust as provided in its Declaration of Trust.


<PAGE>

         With respect to any  obligation of the Trust on behalf of any Portfolio
arising  hereunder,  the Advisor shall look for payment or  satisfaction of such
obligations  solely to the assets and  property of the  Portfolio  to which such
obligation  relates  as  though  the Trust had  separately  contracted  with the
Advisor by separate written instrument with respect to each Portfolio.

7.  DURATION AND TERMINATION OF THIS AGREEMENT

                  (a) Duration.  This  Agreement  shall become  effective on the
         date hereof. Unless terminated as herein provided, this Agreement shall
         remain in full force and  effect  for two years  from the date  hereof.
         Subsequent  to such initial  period of  effectiveness,  this  Agreement
         shall continue in full force and effect for  successive  periods of one
         year  thereafter  with  respect  to  each  Portfolio  so  long  as such
         continuance  with  respect  to such  Portfolio  is  approved  at  least
         annually  (a) by  either  the  Trustees  of the  Trust  or by vote of a
         majority of the outstanding  voting  securities (as defined in the 1940
         Act) of such  Portfolio,  and (b),  in either  event,  by the vote of a
         majority  of the  Trustees  of the  Trust who are not  parties  to this
         Agreement or  "interested  persons" (as defined in the 1940 Act) of any
         such  party,  cast in person at a meeting  called  for the  purpose  of
         voting on such approval.

                  (b) Amendment.  Any amendment to this  Agreement  shall become
         effective  with respect to a Portfolio upon approval by the Advisor and
         the Trustees,  and to the extent required by applicable law, a majority
         of the  outstanding  voting  securities (as defined in the 1940 Act) of
         that Portfolio.

                  (c) Termination. This Agreement may be terminated with respect
         to any Portfolio at any time,  without payment of any penalty,  by vote
         of the  Trustees  or by vote of a majority  of the  outstanding  voting
         securities  (as defined in the 1940 Act) of that  Portfolio,  or by the
         Advisor, in each case upon sixty (60) days' prior written notice to the
         other  party.  Any  termination  of  this  Agreement  will  be  without
         prejudice to the completion of  transactions  already  initiated by the
         Advisor  on behalf of the  Trust at the time of such  termination.  The
         Advisor  shall  take  all  steps   reasonably   necessary   after  such
         termination   to  complete   any  such   transactions   and  is  hereby
         authorization  to take such steps.  In addition,  this Agreement may be
         terminated with respect to one or more Portfolios without affecting the
         rights, duties or obligations of any of the other Portfolios.

                  (d) Automatic Termination.  This Agreement shall automatically
         and immediately terminate in the event of its assignment (as defined in
         the 1940 Act).

                  (e)   Approval,   Amendment  or   Termination   by  Individual
         Portfolio. Any approval,  amendment or termination of this Agreement by
         the  holders of a majority of the  outstanding  voting  securities  (as
         defined  in the  1940  Act) of any  Portfolio  shall  be  effective  to
         continue,  amend or terminate  this  Agreement with respect to any such
         Portfolio notwithstanding (i) that such action has not been approved by
         the holders of a majority of the outstanding  voting  securities of any
         other  Portfolio  affected  thereby,  and (ii) that such action has not
         been  approved  by the vote of a  majority  of the  outstanding  voting
         securities  of the Trust,  unless such action  shall be required by any
         applicable law or otherwise.


<PAGE>

                  (f) Use of Name.  The parties  acknowledge  and agree that the
         names "ProFunds", "VP ProFunds" (collectively, the "ProFund Names") and
         any  derivatives  thereof,  as well as any logos  that are now or shall
         hereafter  be  associated  with  the  ProFund  Names  are the  valuable
         property of the Advisor. In the event that this Agreement is terminated
         and the Advisor no longer acts as Investment  Advisor to the Trust, the
         Advisor  reserves  the  right  to  withdraw  from  the  Trust  and  the
         Portfolios  the uses of the ProFund Names and logos or any name or logo
         misleadingly  implying a continuing  relationship  between the Trust of
         the Portfolios and the Advisor or any of its affiliates.

8.  SERVICES NOT EXCLUSIVE.

         The services of the Advisor to the Trust hereunder are not to be deemed
exclusive, and the Advisor shall be free to render similar services to others so
long as its services hereunder are not impaired thereby.

9.  MISCELLANEOUS

                  (a)  Notice.  Any  notice  under  this  Agreement  shall be in
         writing,  addressed and delivered or mailed,  postage  prepaid,  to the
         other  party at such  address  as such  other  party may  designate  in
         writing for the receipt of such notices.

                  (b) Severability.  If any provision of this Agreement shall be
         held or made invalid by a court  decision,  statue,  rule or otherwise,
         the remainder shall not be thereby affected.

                  (c)  Applicable  Law.  This  Agreement  shall be  construed in

                              AMENDED AND RESTATED
                   MULTIPLE CLASS PLAN PURSUANT TO RULE 18f-3
                                       FOR
                                    PROFUNDS


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

         WHEREAS,  shares of  beneficial  interest  of the  Trust are  currently
divided  into a number of  separate  series,  including  the Bull  ProFund,  the
UltraBull  ProFund,  the Bear  ProFund,  the  UltraBear  ProFund,  the  UltraOTC
ProFund,  the UltraShort OTC ProFund,  the UltraEurope  ProFund,  the UltraShort
Europe ProFund,  the  UltraSmall-Cap  ProFund,  the  UltraMid-Cap  ProFund,  the
UltraJapan ProFund,  and the Money Market ProFund  (collectively,  the "Funds");
and

         WHEREAS, the Trust desires to adopt, on behalf of each of the Funds, an
Amended and Restated  Multiple  Class Plan  pursuant to Rule 18f-3 under the Act
(the "Plan") with respect to each of the Funds.

         NOW,  THEREFORE,  the Trust hereby adopts,  on behalf of the Funds, the
Plan,  in accordance  with Rule 18f-3 under the Act on the  following  terms and
conditions:

         1.  Features  of the  Classes.  Each of the Funds  issues its shares of
beneficial  interest in two classes:  "Investor  Shares" and  "Service  Shares."
Shares of each class of a Fund shall  represent  an equal pro rata  interest  in
such Fund and, generally,  shall have identical voting,  dividend,  liquidation,
and other rights, preferences, powers, restrictions, limitations, qualifications
and terms and  conditions,  except  that:  (a) each class shall have a different
designation;  (b) each class of shares shall bear any Class Expenses, as defined
in Section 4 below;  and (c) each class shall have separate voting rights on any
matter submitted to shareholders in which the interests of one class differ from
the  interests of any other  class.  In  addition,  Investor  Shares and Service
Shares shall have the features described in Sections 3, 4 and 5 below.

         2. Sales Charge Structure. Shares of each class shall be offered at the
then-current net asset value without the imposition of a front-end or contingent
deferred sales charge.

         3.       Service Plan.

                  (a) Service  Shares have adopted a shareholder  servicing plan
pursuant  to which  it may pay  registered  investment  advisers,  banks,  trust
companies  and other  financial  organizations  a fee at an annual rate of up to
1.00% of the average daily net assets of a Fund's Service Shares attributable to
or held in the name of an Authorized Firm for providing  service  activities for
its clients who are beneficial owners of Service Shares.
<PAGE>

                  (b) As used herein,  the term "service  activities" shall mean
activities in connection with the provision of personal,  continuing services to
investors  in each Fund;  receiving,  aggregating  and  processing  purchase and
redemption   orders;   providing  and   maintaining   retirement  plan  records;
communicating   periodically  with  shareholders  and  answering  questions  and
handling  correspondence  from shareholders about their accounts;  acting as the
sole  shareholder of record and nominee for  shareholders;  maintaining  account
records and  providing  beneficial  owners with account  statements;  processing
dividend payments;  issuing shareholder  reports and transaction  confirmations;
providing  subaccounting services for Fund shares held beneficially;  forwarding
shareholder  communications  to beneficial  owners;  receiving,  tabulating  and
transmitting proxies executed by beneficial owners;  performing daily investment
("sweep")  functions for shareholders;  providing  investment advisory services;
and general account administration activities. Overhead and other expenses of an
Authorized  Firm related to its "service  activities,"  including  telephone and
other  communications  expenses,  may be included in the  information  regarding
amounts expended for such activities.

         4. Allocation of Income and Expenses. (a) The gross income of each Fund
generally  shall be allocated  to each class on the basis of net assets.  To the
extent  practicable,  certain  expenses  (other  than Class  Expenses as defined
below, which shall be allocated more specifically)  shall be subtracted from the
gross  income on the basis of the net  assets of each  class of the Fund.  These
expenses include:

                  (1) Expenses incurred by the Trust (including, but not limited
to,  fees of  Trustees,  insurance  and legal  counsel)  not  attributable  to a
particular Fund or to a particular class of shares of a Fund  ("Corporate  Level
Expenses"); and

                  (2)  Expenses  incurred  by a  Fund  not  attributable  to any
particular  class of the Fund's shares (for example,  advisory  fees,  custodial
fees, or other expenses  relating to the management of the Fund's assets) ("Fund
Expenses").

         (b) Expenses  attributable  to a particular  class  ("Class  Expenses")
shall be limited to: (i) payments made pursuant to a shareholder  services plan;
(ii) transfer agent fees  attributable to a specific  class;  (iii) printing and
postage  expenses  related  to  preparing  and  distributing  materials  such as
shareholder  reports,  prospectuses  and  proxies to current  shareholders  of a
specific  class;  (iv)  Blue Sky  registration  fees  incurred  by a class;  (v)
Securities and Exchange  Commission  registration fees incurred by a class; (vi)
the expense of administrative personnel and services to support the shareholders
of a specific class; (vii) litigation or other legal expenses relating solely to
one class;  and (viii) Trustees' fees incurred as a result of issues relating to
one class.  Expenses in category  (i) above must be  allocated  to the class for
which  such  expenses  are  incurred.  All  other  "Class  Expenses"  listed  in
categories  (ii)-(viii)  above  may be  allocated  to a  class,  but only if the
President and Chief Financial Officer have determined, subject to Board approval
or  ratification,  which of such categories of expenses will be treated as Class
Expenses,  consistent with  applicable  legal  principles  under the Act and the
Internal Revenue Code of 1986, as amended (the "Code").
<PAGE>

         Therefore,  expenses  of a Fund shall be  apportioned  to each class of
shares depending on the nature of the expense item. Corporate Level Expenses and
Fund  Expenses  will be  allocated  among the  classes of shares  based on their
relative  net asset  values in  relation  to the net asset  value of the  Trust.
Approved Class Expenses shall be allocated to the particular class to which they
are attributable.  In addition, certain expenses may be allocated differently if
their method of  imposition  changes.  Thus, if a Class Expense can no longer be
attributed  to a class,  it  shall be  charged  to a Fund for  allocation  among
classes,  as determined by the Board of Trustees.  Any additional Class Expenses
not  specifically   identified  above  which  are  subsequently  identified  and
determined  to be  properly  allocated  to one class of  shares  shall not be so
allocated  until  approved by the Board of Trustees of the Trust in light of the
requirements of the Act and the Code.

         5. Exchange  Privileges.  Shareholders may exchange shares of one class
of a Fund at net asset value  without  any sales  charge for shares of any other
class of the Fund or for shares of any class offered by another  Fund,  provided
that  the  amount  to be  exchanged  meets  the  applicable  minimum  investment
requirements and the exchange is made in states where it is legally authorized.

         6. Conversion  Features.  The Funds currently do not offer a conversion
feature.

         7. Quarterly and Annual Reports.  The Trustees shall receive  quarterly
and annual  statements  concerning  all allocated  Class  Expenses and servicing
expenditures.  In the statements, only expenditures properly attributable to the
servicing of a particular  class of shares will be used to justify any servicing
fee or other  expenses  charged to that class.  Expenditures  not related to the
servicing  of a  particular  class  shall not be  presented  to the  Trustees to
justify any fee attributable to that class.

         8.  Accounting   Methodology.   The  following   procedures   shall  be
implemented  in order to meet the  objective of properly  allocating  income and
expenses among the Funds:

                  (1) On a daily basis, a fund  accountant  shall  calculate the
shareholder  services fee to be charged to the Service Shares by calculating the
average  daily net asset  value of such  shares  outstanding  and  applying  the
applicable fee rate of the class to the result of that calculation.

                  (2) The fund  accountant  will  allocate all other  designated
Class Expenses, if any, to the respective classes.

                  (3) The fund  accountant  shall allocate  income and Corporate
Level and Fund Expenses among the respective  classes of shares based on the net
asset  value of each class in  relation  to the net asset  value of the Fund for
Fund Expenses, and in relation to the net asset value of the Trust for Corporate
Level Expenses.  These  calculations  shall be based on net asset values for all
Funds  except  the  Money  Market  ProFund,  for  which  it will be based on the
relative value of settled shares.
<PAGE>

                  (4) The  fund  accountant  shall  then  complete  a  worksheet
developed  for  purposes of  complying  with  Section 8 of this Plan,  using the
allocated  income and expense  calculations  from  paragraph (3) above,  and the
additional fees calculated from paragraphs (1) and (2) above.

                  (5) The fund  accountant  shall  develop  and use  appropriate
internal  control  procedures  to assure the  accuracy of its  calculations  and
appropriate allocation of income and expenses in accordance with this Plan.

         9.  Waiver or  Reimbursement  of  Expenses.  Expenses  may be waived or
reimbursed by the adviser to the Trust or any other  provider of services to the
Trust without the prior approval of the Trust's Board of Trustees.

         10. Effectiveness of Plan. This Plan shall not take effect until it has
been  approved by votes of a majority of both (a) the  Trustees of the Trust and
(b) the independent Trustees.

         11.  Material  Modifications.  This Plan may not be  amended  to modify
materially  its terms unless such  amendment is approved in the manner  provided
for initial approval in paragraph 10 hereof.

         12.  Limitation  of  Liability.  The  Trustees  of the  Trust  and  the
shareholders  of each Fund shall not be liable for any  obligations of the Trust
or any Fund under this Plan,  and any person,  in asserting any rights or claims
under this Plan, shall look only to the assets and property of the Trust or such
Funds  in  settlement  of such  right  or  claim,  and not to such  Trustees  or
shareholders.

         IN WITNESS WHEREOF, the Trust, on behalf of the Funds, has adopted this
Amended and Restated Multiple Class Plan as of [______], 2000.
