                                    OVERVIEW


THE ULTRASECTOR PROFUNDS' INVESTMENT STRATEGY

            The  investment  objective  of each  UltraSector  ProFund is capital
appreciation.  Each  UltraSector  ProFund  seeks to  achieve  its  objective  by
creating investment exposure  approximating twice its net assets to the equities
of companies within a specified economic sector.

THE ADVISOR'S INVESTMENT METHODOLOGY

            In managing the UltraSector ProFunds, the investment team of ProFund
Advisors  LLC (the  "Advisor")  employs a  quantitative  model that  considers a
number of  factors  to  develop a liquid  portfolio  of stocks  that  adequately
represents a particular market sector.  Specifically,  the Advisor's  investment
process  screens the broad  universe of stocks of issuers that are  "principally
engaged" in business  activities  in each  industry  sector  primarily  based on
liquidity,  market  capitalization,  and  correlation  relative  to  the  entire
industry sector. The Advisor also may consider other factors.

            The Advisor  monitors the  UltraSector  ProFunds'  portfolios  on an
ongoing basis,  and adds or deletes stocks from the portfolios as needed.  After
constructing a portfolio for each  UltraSector  ProFund,  the Advisor intends to
utilize futures contracts,  options,  swaps, and other financial  instruments to
leverage an UltraSector  ProFund's exposure to the relevant business sector. The
use of leverage  will result in each  UltraSector  ProFund  being exposed to its
relevant business sector with approximately 200% of its total assets.

            Each business sector typically consists of numerous industries.  For
purposes of the  Advisor's  investment  methodology  and the  policies  for each
UltraSector  ProFund,  a company is considered to be "principally  engaged" in a
designated  business activity in a particular economic sector if at least 50% of
its assets, gross income, or net profits are committed to, or derived from, that
activity.  If a question  exists as to whether a company meets these  standards,
the Advisor will determine  whether the company's primary business is within the
business sector designated for investment by that UltraSector ProFund.

RISKS OF INVESTING IN THE ULTRASECTOR PROFUNDS

            Your  investment in the  UltraSector  ProFunds is subject to certain
risks.  Some of the risks  that are common to each of the  UltraSector  ProFunds
are:

          .    Market  Risk -- The  UltraSector  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.

          .    Equity Risk -- The equity markets are volatile,  and the value of
               an  UltaSector  ProFund's  securities  and  futures  and  options
               contracts  may  fluctuate   drastically  from  day-to-day.   This
               volatility  may  cause  the  value  of  your   investment  in  an
               UltraSector ProFund to decrease. The risk of equity investing may
               be particularly acute when an UltraSector  ProFund invests in the
               securities of issuers with small market capitalization.
<PAGE>

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

          .    Concentration  Risk -- Since the  UltraSector  ProFunds invest in
               the securities of a limited number of issuers conducting business
               in a specific  market  sector,  they are subject to the risk that
               those issuers (or that  industry)  will perform  poorly,  and the
               UltraSector  ProFund  will be  negatively  impacted  by that poor
               performance.

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

          .    Leverage  Risk  --  The  UltraSector  ProFunds  employ  leveraged
               investment techniques. Leverage is the ability to get a return on
               a  capital  base  that is larger  than an  UltraSector  ProFund's
               investment. Use of leverage can magnify the effects of changes in
               the value of these  ProFunds  and makes them more  volatile.  The
               leveraged  investment  techniques that the  UltraSector  ProFunds
               employ  should  cause  investors  in these  ProFunds to lose more
               money in adverse environments.

          .    Risks of  Aggressive  Investment  Techniques  -- The  UltraSector
               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 prices changes  (losses) in the value of the instruments
               and imperfect  correlations between the price of the contract and
               the underlying security or index.

          .    New Fund Risk.  There can be no  assurances  that an  UltraSector
               ProFund will grow to an  economically  viable size, in which case
               the ProFund management may determine to liquidate the UltraSector
               ProFund at a time that may not be opportune for shareholders.

            The   investment   objective   of  each   UltraSector   ProFund   is
non-fundamental and may be changed without shareholder approval. There can be no
assurance that an UltraSector ProFund will achieve its investment objective.

                       FUND INFORMATION -- BANKING PROFUND

FUND STRATEGY

ICON The investment  objective of the Banking  ProFund is capital  appreciation.
The Banking  ProFund  seeks to achieve  its  objective  by  creating  investment
exposure  approximating  twice its net assets to the  equities of the  companies
within the banking sector.

PORTFOLIO INVESTMENTS

ICON The  Banking  ProFund  invests  substantially  all of its  assets in equity
securities of Banking  Companies that are traded in the United  States.  Banking
Companies  are  engaged  in  accepting   deposits  and  making   commercial  and
principally  non-mortgage  consumer  loans and include  state  chartered  banks,
savings and loan institutions, and banks that are members of the Federal Reserve
System.  The  Banking  ProFund  may also  engage in  futures,  options and swaps
transactions  or other  financial  instruments,  which  would  allow the Banking
ProFund to  leverage  its  exposure  to  Banking  Companies,  purchase  American
Depositary  Receipts  ("ADRs") and U.S.  Government  securities,  and enter into
repurchase agreements.

RISK CONSIDERATIONS

ICON The  Banking  ProFund is subject to a number of risks that will  affect the
value of its shares, including:

 .    Banking Sector  Concentration  Risk -- The securities of Banking  Companies
     that the Banking ProFund  purchases may underperform the market as a whole.
     To the extent that the Banking  ProFund's  investments are  concentrated in
     Banking  Companies,  the  Banking  ProFund  is subject  to  legislative  or
     regulatory changes,  adverse market conditions and/or increased competition
     affecting  Banking  Companies.  The  prices of the  securities  of  Banking
     Companies  may  fluctuate  widely due to the  broadening  of  regional  and
     national  interstate  banking  powers,  the  reduction  in  the  number  of
     publicly-traded  Banking Companies,  and general economic  conditions which
     could create exposure to credit losses.

FUND PERFORMANCE AND FEE INFORMATION

            Because  the  UltraSector  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.

FEES AND EXPENSES OF THE FUND

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

redemptions  under  $5,000.  This charge may be waived at the  discretion of the
Banking ProFund.

EXAMPLES

           The  following  examples  illustrate  the  expenses  you  would  have
incurred on a $10,000  investment  in the Banking  ProFund,  and are intended to
help you compare the cost of investing in the Banking ProFund  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 the Banking  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.

                   FUND INFORMATION - BASIC MATERIALS PROFUND

FUND STRATEGY

ICON  The  investment  objective  of the  Basic  Materials  ProFund  is  capital
appreciation.  The Basic  Materials  ProFund  seeks to achieve its  objective by
creating investment exposure  approximating twice its net assets to the equities
of the companies within the basic materials sector.

PORTFOLIO INVESTMENTS

ICON The Basic  Materials  ProFund  invests  substantially  all of its assets in
equity  securities of Basic  Materials  Companies  that are traded in the United
States.  Basic  Materials  Companies  are  engaged in the  manufacture,  mining,
processing,  or distribution of raw materials and intermediate goods used in the
industrial  sector,  and may be involved in the production of metals,  textiles,
and wood  products,  including  equipment  suppliers  and  railroads.  The Basic
Materials ProFund may also engage in futures,  options and swaps transactions or
other financial instruments, which would allow the Fund to leverage its exposure
in the basic materials sector, purchase ADRs and U.S. Government securities, and
enter into repurchase agreements.

RISK CONSIDERATIONS

ICON The Basic  Materials  ProFund  is  subject  to a number of risks  that will
affect the value of its shares, including:

 .    BasicMaterials  Sector  Concentration  Risk -- The securities of issuers in
     the basic materials sector that the Basic Materials  ProFund  purchases may
     underperform  the market as a whole. To the extent that the Basic Materials
     ProFund's  investments are concentrated in issuers  conducting  business in
     the same  economic  sector,  the Basic  Materials  ProFund  is  subject  to
     legislative  or  regulatory  changes,   adverse  market  conditions  and/or
     increased  competition  affecting that economic  sector.  The prices of the
     securities of Basic  Materials  Companies  may fluctuate  widely due to the
     level and volatility of commodity prices, the exchange value of the dollar,
     import controls, worldwide competition, liability for environmental damage,
     depletion of resources,  and mandated expenditures for safety and pollution
     control devices.

FUND PERFORMANCE AND FEE INFORMATION

            Because  the  UltraSector  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

ICON The Biotechnology  ProFund is subject to a number of risks that will affect
the value of its shares, including:

 .    Biotechnology  Sector Concentration Risk -- The risk that the securities of
     issuers  in the  biotechnology  sector  that  the  ProFund  purchases  will
     underperform  the market as a whole.  To the extent that the  Biotechnology
     ProFund's  investments are concentrated in issuers  conducting  business in
     the  same  economic  sector,  the  Biotechnology   ProFund  is  subject  to
     legislative  or  regulatory  changes,   adverse  market  conditions  and/or
     increased  competition  affecting that economic  sector.  The prices of the
     securities of  Biotechnology  Companies may fluctuate  widely due to patent
     considerations,   intense  competition,   rapid  technological  change  and
     obsolescence,   and   regulatory   requirements   of  the   Food  and  Drug
     Administration,  the  Environmental  Protection  Agency,  state  and  local
     governments, and foreign regulatory authorities.

     .    Small  Company  Investment  Risk -- The  Biotechnology  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.
<PAGE>

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

                  FUND INFORMATION -- CONSUMER PRODUCTS PROFUND

FUND STRATEGY

ICON The  investment  objective  of the  Consumer  Products  ProFund  is capital
appreciation.  The Consumer  Products  ProFund seeks to achieve its objective by
creating investment exposure  approximating twice its net assets to the equities
of the companies within the consumer products sector.

PORTFOLIO INVESTMENTS

ICON The Consumer  Products ProFund invests  substantially  all of its assets in
equity securities of Consumer  Products  Companies that are traded in the United
States.   Consumer  Products   Companies  include  companies  that  manufacture,
wholesale  or  retail  durable  goods  such as  major  appliances  and  personal
computers,  or that retail non-durable goods such as beverages,  tobacco, health
care products,  household and personal care products, apparel, and entertainment
products (e.g., books, magazines,  TV, cable, movies, music, gaming, sports), as
well as companies that provide  consumer  products and services such as lodging,
child care,  convenience stores, and car rentals.  The Consumer Products ProFund
may also engage in futures,  options and swaps  transactions  or other financial
instruments,  which would allow the  Consumer  Products  ProFund to leverage its
exposure to the consumer  products  sector,  purchase  ADRs and U.S.  Government
securities, and enter into repurchase agreements.

RISK CONSIDERATIONS

ICON The  Consumer  Products  ProFund  is subject to a number of risks that will
affect the value of its shares, including:

 .    Consumer Products Sector Concentration Risk -- The securities of issuers in
     the consumer  products sector that the Consumer  Products ProFund purchases
     may  underperform  the market as a whole.  To the extent that the  Consumer
     Products  ProFund's  investments  are  concentrated  in issuers  conducting
     business in the same  economic  sector,  the Consumer  Products  ProFund is
     subject to legislative  or regulatory  changes,  adverse market  conditions
     and/or  increased   competition   affecting  that  economic   sector.   The
     performance of Consumer  Products  Companies has historically  been closely
     tied to the  performance  of the overall  economy,  and is also affected by
     interest  rates,  competition,  consumer  confidence and relative levels of
     disposable  household  income and seasonal  consumer  spending.  Changes in
     demographics  and  consumer  tastes can also  affect the  demand  for,  and
     success of, consumer products in the marketplace.

companies within the electronics sector.

PORTFOLIO INVESTMENTS

ICON The Electronics  ProFund invests  substantially all of its assets in equity
securities  of  Electronics  Companies  that are  traded in the  United  States.
Electronics   Companies  include  companies  involved  in  the  manufacture  and
development  of  semiconductors,  connectors,  printed  circuit boards and other
components; equipment vendors to electronic component manufacturers;  electronic
component  distributors;  electronic instruments and electronic systems vendors;
and also include companies  involved in all aspects of the electronics  business
and in new technologies or specialty areas such as defense electronics, advanced
design and manufacturing  technologies,  or lasers. The Electronics  ProFund may

     regulatory changes,  adverse market conditions and/or increased competition
     affecting that economic sector. The prices of the securities of Electronics
     Companies  may  fluctuate  widely  due to risks of  rapid  obsolescence  of
     products, intense competition, the economic performance of their customers,
     high  technology  and  research  costs  (especially  in light of  decreased
     defense  spending by the U.S.  Government),  and may face  competition from
     subsidized foreign competitors with lower production costs.

 .    Small Company  Investment Risk -- The Electronics  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.

FUND STRATEGY

ICON The investment objective of the Energy ProFund is capital appreciation. The
Energy  ProFund seeks to achieve its objective by creating  investment  exposure

energy sector.

PORTFOLIO INVESTMENTS

ICON The  Energy  ProFund  invests  substantially  all of its  assets  in equity
securities  of Energy  Companies  that are traded in the United  States.  Energy
Companies  are  involved in all aspects of the energy  industry,  including  the
conventional areas of oil, gas,  electricity,  and coal, and alternative sources
of energy such as nuclear,  geothermal,  oil shale, and solar power, and include
companies  that  produce,   transmit,  market,  distribute  or  measure  energy;
companies involved in providing products and services to companies in the energy
field;  and  companies  involved  in the  exploration  of new sources of energy,
conservation,  and energy-related pollution control. The Energy ProFund may also

     ProFund is subject to  legislative  or regulatory  changes,  adverse market
     conditions and/or increased competition affecting that economic sector. The
     prices of the  securities of Energy  Companies may fluctuate  widely due to
     changes in value and dividend yield,  which depend largely on the price and
     supply of energy  fuels,  international  political  events  relating to oil
     producing  countries,  energy  conservation,  the  success  of  exploration
     projects, and tax and other governmental regulatory policies.

                   FUND INFORMATION -- ENERGY SERVICES PROFUND

FUND STRATEGY

ICON  The  investment  objective  of the  Energy  Services  ProFund  is  capital
appreciation.  The Energy  Services  ProFund  seeks to achieve its  objective by
creating investment exposure  approximating twice its net assets to the equities
of the companies within the energy services sector.

PORTFOLIO INVESTMENTS

ICON The Energy  Services  ProFund  invests  substantially  all of its assets in
equity  securities of Energy  Services  Companies  that are traded in the United
States.  Energy Services  Companies are engaged in one or more businesses in the
energy service  field,  including  those that provide  services and equipment to
companies  engaged in the  production,  refinement or  distribution of oil, gas,
electricity, and coal; companies involved with the production and development of
newer sources of energy such as nuclear, geothermal, oil shale, and solar power;
companies  involved  with onshore or offshore  drilling;  companies  involved in
production and well maintenance;  companies involved in exploration engineering,
data and  technology;  companies  involved in energy  transport;  and  companies
involved in equipment  and plant  design or  construction.  The Energy  Services
ProFund  may also engage in futures,  options  and swaps  transactions  or other
financial instruments, which would allow the Energy Services ProFund to leverage
its exposure to the energy services  sector,  purchase ADRs and U.S.  Government
securities, and enter into repurchase agreements.

RISK CONSIDERATIONS

ICON The  Energy  Services  ProFund  is  subject  to a number of risks that will
affect the value of its shares, including:

 .    Energy Services Sector  Concentration  Risk -- The securities of issuers in
     the energy services sector that the Energy Services  ProFund  purchases may
     underperform  the market as a whole. To the extent that the Energy Services
     ProFund's  investments are concentrated in issuers  conducting  business in
     the same  economic  sector,  the  Energy  Services  ProFund  is  subject to
     legislative  or  regulatory  changes,   adverse  market  conditions  and/or
     increased  competition  affecting that economic  sector.  The prices of the
     securities of Energy  Services  Companies  may fluctuate  widely due to the
     supply and demand both for their  specific  products  or  services  and for
     energy  products  in  general,  the price of oil and gas,  exploration  and
     production spending,  governmental regulation and environmental issues, and
     world events and economic  conditions  generally  affecting  energy  supply
     companies.

FUND PERFORMANCE AND FEE INFORMATION

            Because  the  UltraSector  ProFunds  are  newly  formed  and have no

                 FUND INFORMATION -- FINANCIAL SERVICES PROFUND

FUND STRATEGY

ICON The  investment  objective  of the  Financial  Services  ProFund is capital
appreciation.  The Financial  Services ProFund seeks to achieve its objective by
creating investment exposure  approximating twice its net assets to the equities
of the companies within the financial services sector.

PORTFOLIO INVESTMENTS

ICON The Financial  Services ProFund invests  substantially all of its assets in
equity securities of Financial  Services Companies that are traded in the United
States.  Financial Service Companies include commercial banks,  savings and loan
associations,   insurance  companies  and  brokerage  companies.  The  Financial
Services ProFund may also engage in futures,  options and swaps  transactions or
other financial instruments, which would allow the Financial Services ProFund to
leverage its exposure to the financial  services sector,  purchase ADRs and U.S.
Government  securities,   and  enter  into  repurchase  agreements.   Under  SEC
regulations,  the Financial  Services ProFund may not invest more than 5% of its
total assets in the equity  securities of any company that derives more than 15%
of its revenues from brokerage or investment management activities.

RISK CONSIDERATIONS

ICON The  Financial  Services  ProFund is subject to a number of risks that will
affect the value of its shares, including:

 .    Financial  Services Sector  Concentration Risk -- The securities of issuers
     in the  financial  services  sector  that the  Financial  Services  ProFund
     purchases may  underperform  the market as a whole.  To the extent that the
     Financial  Services  ProFund's  investments  are  concentrated  in  issuers
     conducting  business in the same economic  sector,  the Financial  Services
     ProFund is subject to  legislative  or regulatory  changes,  adverse market
     conditions  and/or  increased  competition  affecting that economic sector.
     Financial  Services   Companies  are  subject  to  extensive   governmental
     regulation,  which may limit both the  amounts and types of loans and other
     financial  commitments  they can  make,  and the  rates  and fees  they can
     charge.  Profitability is largely dependent on the availability and cost of
     capital, and can fluctuate significantly when interest rates change. Credit
     losses  resulting  from  financial   difficulties  of  borrowers  also  can
     negatively impact the sector.

FUND PERFORMANCE AND FEE INFORMATION

            Because  the  UltraSector  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.

the Financial Services ProFund.

EXAMPLES

           The  following  examples  illustrate  the  expenses  you  would  have
incurred on a $10,000  investment in the  Financial  Services  ProFund,  and are
intended to help you compare the cost of  investing  in the  Financial  Services
ProFund  compared to other mutual funds. The examples assume that you invest for

that the  Financial  Services  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.

                     FUND INFORMATION -- HEALTH CARE PROFUND

FUND STRATEGY

ICON  The   investment   objective   of  the  Health  Care  ProFund  is  capital
appreciation. The Health Care ProFund seeks to achieve its objective by creating
investment  exposure  approximating  twice its net assets to the equities of the
companies within the health care sector.

PORTFOLIO INVESTMENTS

ICON The Health Care ProFund invests  substantially  all of its assets in equity
securities of Health Care Companies that are traded in the United States. Health
Care Companies include pharmaceutical companies,  companies involved in research
and development of pharmaceutical  products and services,  companies involved in
the operation of health care  facilities,  and other  companies  involved in the
design,  manufacture,  or sale of health care-related products or services.  The
Health Care ProFund may also engage in futures,  options and swaps  transactions
or other  financial  instruments  which would  allow the Health Care  ProFund to
leverage  its  exposure  to the  health  care  sector,  purchase  ADRs  and U.S.
Government securities, and enter into repurchase agreements.

RISK CONSIDERATIONS

ICON The Health  Care  ProFund is subject to a number of risks that will  affect
the value of its shares, including:

 .    Health Care Sector  Concentration  Risk -- The risk that the  securities of
     issuers in the health care sector  that the Health Care  ProFund  purchases
     may  underperform the market as a whole. To the extent that the Health Care
     ProFund's  investments are concentrated in issuers  conducting  business in
     the same economic sector, the Health Care ProFund is subject to legislative
     or  regulatory   changes,   adverse  market   conditions  and/or  increased
     competition affecting that economic sector. The prices of the securities of
     Health Care Companies may fluctuate widely due to government regulation and
     approval  of their  products  and  services,  which can have a  significant
     effect on their price and availability.  Furthermore, the types of products
     or services  produced or provided  by these  companies  may quickly  become
     obsolete.  Moreover,  liability  for products  that are later alleged to be
     harmful or unsafe may be substantial,  and may have a significant impact on
     a Health Care Company's market value and/or share price.

FUND PERFORMANCE AND FEE INFORMATION

            Because  the  UltraSector  ProFunds  are  newly  formed  and have no

                      FUND INFORMATION -- INTERNET PROFUND

FUND STRATEGY

ICON The investment  objective of the Internet ProFund is capital  appreciation.
The  Internet  ProFund  seeks to achieve its  objective  by creating  investment
exposure  approximating  twice its net assets to the  equities of the  companies
within the Internet sector.

PORTFOLIO INVESTMENTS

ICON The  Internet  ProFund  invests  substantially  all of its assets in equity
securities  of  Internet  Companies  that are traded in the United  States.  The
Internet  is a global  network of  computers  that  allows  users to quickly and
easily share information and conduct business.  Internet Companies are companies
which the Advisor  believes  have,  or will  develop,  products,  processes,  or
services  that will provide  advances and  improvements  to the Internet and the
World Wide Web. These companies may include companies which develop hardware and
software for personal computers, semiconductors, and semiconductor equipment, or
companies engaged in the transmission of voice, video and data over the Internet
and the World Wide Web. The Internet ProFund may also engage in futures, options
and swaps  transactions  or other  financial  instruments  which would allow the
Internet ProFund to leverage its exposure to the Internet sector,  purchase ADRs
and U.S. Government securities, and enter into repurchase agreements.

RISK CONSIDERATIONS

ICON The  Internet  ProFund is subject to a number of risks that will affect the
value of its shares, including:

 .    Internet  Sector  Concentration  Risk -- The  securities  of issuers in the
     technology sector that the ProFund purchases may underperform the market as
     a whole.  Due to the  rapidly  changing  field of Internet  Companies,  the
     prices  of  their  securities  may  fluctuate  widely  due  to  competitive
     pressures,  increased  sensitivity  to short product  cycles and aggressive
     pricing,  problems relating to bringing their products to market, very high
     price/earnings  ratios,  and high  personnel  turnover  due to severe labor
     shortages for skilled technology professionals.

 .    Small Company  Investment  Risk -- The Internet  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.

                       FUND INFORMATION -- LEISURE PROFUND

FUND STRATEGY

ICON The investment  objective of the Leisure  ProFund is capital  appreciation.
The Leisure  ProFund  seeks to achieve  its  objective  by  creating  investment
exposure  approximating  twice its net assets to the  equities of the  companies
within the leisure sector.

PORTFOLIO INVESTMENTS

ICON The  Leisure  ProFund  invests  substantially  all of its  assets in equity
securities of Leisure  Companies that are traded in the United  States.  Leisure
Companies are engaged in the design,  production,  or  distribution  of goods or
services  in the  leisure  industries.  Leisure  Companies  include  hotels  and
resorts,  casinos,  radio and television  broadcasting and  advertising,  motion
picture production, toys and sporting goods manufacture,  musical recordings and
instruments,  alcohol and tobacco, and publishing.  The Leisure ProFund may also
engage in futures, options and swaps transactions or other financial instruments
which would allow the Leisure  ProFund to leverage  its  exposure to the leisure
sector, purchase ADRs and U.S. Government securities,  and enter into repurchase
agreements.

RISK CONSIDERATIONS

ICON The  Leisure  ProFund is subject to a number of risks that will  affect the
value of its shares, including:

 .    Leisure  Sector  Concentration  Risk -- The  securities  of  issuers in the
     leisure  sector that the Leisure  ProFund  purchases may  underperform  the
     market as a whole. To the extent that the Leisure ProFund's investments are
     concentrated in issuers  conducting  business in the same economic  sector,
     the  Leisure  ProFund is  subject to  legislative  or  regulatory  changes,
     adverse  market  conditions  and/or  increased  competition  affecting that
     economic  sector.   Securities  of  Leisure  Companies  may  be  considered
     speculative,  and generally  exhibit  greater  volatility  than the overall
     market.  The prices of the  securities  of Leisure  Companies may fluctuate
     widely due to  unpredictable  earnings,  due in part to  changing  consumer
     tastes  and  intense   competition,   strong   reaction  to   technological
     developments  and  to  the  threat  of  increased  government   regulation,
     particularly in the gaming arena.

FUND PERFORMANCE AND FEE INFORMATION

            Because  the  UltraSector  ProFunds  are  newly  formed  and have no

                   FUND INFORMATION -- PRECIOUS METALS PROFUND

FUND STRATEGY

ICON  The  investment  objective  of the  Precious  Metals  ProFund  is  capital
appreciation.  The Precious  Metals  ProFund  seeks to achieve its  objective by
creating investment exposure  approximating twice its net assets to the equities
of the companies within the precious metals sector.

PORTFOLIO INVESTMENTS

ICON The Precious  Metals  ProFund  invests  substantially  all of its assets in
equity  securities of Precious  Metals  Companies  that are traded in the United
States and foreign countries. Precious metals include gold, silver, platinum and
other  precious  metals.   Precious  Metals  Companies  include  precious  metal
manufacturers;  distributors of precious metal products,  such as jewelry, metal
foil or bullion;  mining and  geological  exploration  companies;  and companies
which provide services to Precious Metals Companies. The Precious Metals ProFund
may also engage in futures,  options and swaps  transactions  or other financial
instruments  which  would allow the  Precious  Metals  ProFund to  leverage  its
exposure to the precious metals sector, purchase ADRs and U.S.
Government securities, and enter into repurchase agreements.

RISK CONSIDERATIONS

ICON The  Precious  Metals  ProFund  is  subject  to a number of risks that will
affect the value of its shares, including:

 .    Precious  Metals  Concentration  Risk -- The  relatively  few securities of
     issuers in the mining industry that the Precious  Metals ProFund  purchases
     may  underperform  the market as a whole.  To the extent that the  Precious
     Metals  ProFund's   investments  are  concentrated  in  issuers  conducting
     business in the same  industry,  the ProFund is subject to  legislative  or
     regulatory changes,  adverse market conditions and/or increased competition
     affecting that industry,  as well as to the volatility of global prices for
     precious metals.  The prices of precious metals may fluctuate widely due to
     changes in  inflation  or inflation  expectations,  currency  fluctuations,
     speculation, worldwide demand and political developments in precious metals
     producing countries.

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

     .    Many  foreign   countries  lack  uniform   accounting  and  disclosure
          standards,  or have  accounting and  disclosure  standards that differ
          from U.S. standards.  Accordingly, the Precious Metals ProFund may not
          have access to adequate or reliable company information.

     .    The Precious  Metals  ProFund will be subject to the market,  economic
          and  political  risks of the  countries  where it invests or where the
          companies are located.

     .    Securities  purchased by the Precious  Metals ProFund may be priced in
          foreign  currencies.  Their value could  change  significantly  as the
          currencies  strengthen  or weaken  relative  to the U.S.  dollar.  The
          Advisor  does not  engage  in  activities  designed  to hedge  against
          foreign currency fluctuations.

                      FUND INFORMATION -- RETAILING PROFUND

FUND STRATEGY

ICON The investment objective of the Retailing ProFund is capital  appreciation.
The  Retailing  ProFund  seeks to achieve its  objective by creating  investment
exposure  approximating  twice its net assets to the  equities of the  companies
within the retailing sector.

PORTFOLIO INVESTMENTS

ICON The Retailing  ProFund  invests  substantially  all of its assets in equity
securities  of  Retailing  Companies  that  are  traded  in the  United  States.
Retailing  Companies include drug and department stores;  suppliers of goods and
services for homes, home improvements and yards; clothing, jewelry,  electronics
and computer retailers; franchise restaurants; motor vehicle and marine dealers;
warehouse  membership clubs; mail order  operations;  and companies  involved in
alternative  selling methods.  The Retailing ProFund may also engage in futures,
options and swaps transactions or other financial  instruments which would allow
the Retailing ProFund to leverage its exposure to the retailing sector, purchase
ADRs and U.S. Government securities, and enter into repurchase agreements.

RISK CONSIDERATIONS

ICON The Retailing  ProFund is subject to a number of risks that will affect the
value of its shares, including:

 .    Retailing  Sector  Concentration  Risk -- The  securities of issuers in the
     retailing sector that the Retailing  ProFund purchases may underperform the
     market as a whole. To the extent that the Retailing  ProFund's  investments
     are  concentrated  in  issuers  conducting  business  in the same  economic
     sector,  the  Retailing  ProFund is subject to  legislative  or  regulatory
     changes,  adverse market conditions and/or increased  competition affecting
     that economic sector.  The prices of the securities of Retailing  Companies
     may fluctuate widely due to consumer spending, which is affected by general
     economic  conditions and consumer confidence levels. The retailing industry
     is highly  competitive,  and a Retailing Company's success is often tied to
     its ability to  anticipate  and react to  changing  consumer  tastes.  Many
     Retailing  Companies  are  thinly  capitalized,  and are  dependent  upon a
     relatively few number of business days to achieve their overall results.

FUND PERFORMANCE AND FEE INFORMATION

            Because  the  UltraSector  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.

                     FUND INFORMATION -- TECHNOLOGY PROFUND

FUND STRATEGY

ICON The investment objective of the Technology ProFund is capital appreciation.
The  Technology  ProFund seeks to achieve its  objective by creating  investment
exposure  approximating  twice its net assets to the  equities of the  companies
within the technology sector.

PORTFOLIO INVESTMENTS

ICON The Technology  ProFund invests  substantially  all of its assets in equity
securities  of  Technology  Companies  that are  traded  in the  United  States.
Technology  Companies are  companies  which the Advisor  believes  have, or will
develop,  products,  processes,  or  services  that will  provide  technological
advances and improvements.  These companies may include, for example,  companies
that  develop,  produce or  distribute  products or  services  in the  computer,
semiconductor,  electronics,  communications,  health  care,  and  biotechnology
sectors.  The Technology  ProFund may also engage in futures,  options and swaps
transactions  or other financial  instruments,  which would allow the Technology
ProFund to leverage its exposure to the  technology  sector,  purchase  ADRs and
U.S. Government securities, and enter into repurchase agreements.

RISK CONSIDERATIONS

ICON The Technology ProFund is subject to a number of risks that will affect the
value of its shares, including:

 .    Technology  Sector  Concentration  Risk -- The securities of issuers in the
     technology  sector that the Technology  ProFund  purchases may underperform
     the  market  as a  whole.  To the  extent  that  the  Technology  ProFund's
     investments  are  concentrated in issuers  conducting  business in the same
     economic  sector,  the  Technology  ProFund is subject  to  legislative  or
     regulatory changes,  adverse market conditions and/or increased competition
     affecting that economic sector.  The prices of the securities of Technology
     Companies  may fluctuate  widely due to  competitive  pressures,  increased
     sensitivity  to short  product  cycles  and  aggressive  pricing,  problems
     relating to bringing  their  products to market,  very high  price/earnings
     ratios,  and high  personnel  turnover  due to severe labor  shortages  for
     skilled technology professionals.

 .    Small Company  Investment Risk -- The Technology  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.

                 FUND INFORMATION -- TELECOMMUNICATIONS PROFUND

FUND STRATEGY

ICON The  investment  objective  of the  Telecommunications  ProFund  is capital
appreciation.  The Telecommunications  ProFund seeks to achieve its objective by
creating investment exposure  approximating twice its net assets to the equities
of the companies within the telecommunications sector.

PORTFOLIO INVESTMENTS

ICON The  Telecommunications  ProFund invests substantially all of its assets in
equity securities of Telecommunications  Companies that are traded in the United
States.   Telecommunications   Companies  range  from   traditional   local  and
long-distance  telephone services or equipment providers,  to companies involved
in  developing  technologies  such as  cellular  telephone  or paging  services,
Internet    equipment   and   service   providers,    and   fiber-optics.    The
Telecommunications  ProFund  may also  engage  in  futures,  options  and  swaps
transactions   or  other   financial   instruments,   which   would   allow  the
Telecommunications  ProFund to leverage its  exposure to the  telecommunications
sector, purchase ADRs and U.S. Government securities,  and enter into repurchase
agreements.  Although  many  established  Telecommunications  Companies  pay  an
above-average  dividend, the  Telecommunications  ProFund's investment decisions
are primarily based on growth potential and not on income.

RISK CONSIDERATIONS

ICON The  Telecommunications  ProFund  is subject to a number of risks that will
affect the value of its shares, including:

 .    Telecommunications  Sector  Concentration Risk -- The securities of issuers
     in  the   telecommunications   sector  that  the  ProFund   purchases   may
     underperform   the   market   as  a   whole.   To  the   extent   that  the
     Telecommunications   ProFund's  investments  are  concentrated  in  issuers
     conducting  business in the same economic  sector,  the  Telecommunications
     ProFund is subject to  legislative  or regulatory  changes,  adverse market
     conditions and/or increased competition affecting that economic sector. The
     prices of the  securities  of  Telecommunications  Companies  may fluctuate
     widely due to both federal and state regulations  governing rates of return
     and services that may be offered,  fierce competition for market share, and
     competitive  challenges  in the U.S.  from foreign  competitors  engaged in
     strategic joint ventures with U.S.  companies,  and in foreign markets from
     both  U.S.  and  foreign   competitors.   In  addition,   recent   industry
     consolidation trends may lead to increased regulation of Telecommunications
     Companies in their primary markets.

FUND PERFORMANCE AND FEE INFORMATION

            Because  the  UltraSector  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

                   FUND INFORMATION -- TRANSPORTATION PROFUND

FUND STRATEGY

ICON  The  investment  objective  of  the  Transportation   ProFund  is  capital
appreciation.  The  Transportation  ProFund  seeks to achieve its  objective  by
creating investment exposure  approximating twice its net assets to the equities
of the companies within the transportation sector.

PORTFOLIO INVESTMENTS

ICON The  Transportation  ProFund  invests  substantially  all of its  assets in
equity  securities  of  Transportation  Companies  that are traded in the United
States. Transportation Companies may include, for example, companies involved in
the movement of freight or people,  such as airline,  railroad,  ship, truck and
bus companies; equipment manufacturers (including makers of trucks, automobiles,
planes,  containers,  railcars  or other  modes of  transportation  and  related
products); parts suppliers; and companies involved in leasing,  maintenance, and
transportation-related  services.  The Transportation ProFund may also engage in
futures,  options and swaps transactions or other financial  instruments,  which
would  allow  the  Transportations  ProFund  to  leverage  its  exposure  to the
transportation sector,  purchase ADRs and U.S. Government securities,  and enter
into repurchase agreements.

RISK CONSIDERATIONS

ICON The Transportation ProFund is subject to a number of risks that will affect
the value of its shares, including:

 .    Transportation  Sector  Concentration  Risk -- The securities of issuers in
     the  transportation  sector that the  Transportation  ProFund purchases may
     underperform  the market as a whole. To the extent that the  Transportation
     ProFund's  investments are concentrated in issuers  conducting  business in
     the  same  economic  sector,  the  Transportation  ProFund  is  subject  to
     legislative  or  regulatory  changes,   adverse  market  conditions  and/or
     increased  competition  affecting that economic  sector.  The prices of the
     securities of  Transportation  Companies may fluctuate  widely due to their
     cyclical  nature,  occasional  sharp price  movements which may result from
     changes in the economy, fuel prices, labor agreements, and insurance costs,
     the recent trend of government deregulation, and increased competition from
     foreign   companies,   many  of  which  are  partially  funded  by  foreign
     governments  and  which  may  be  less  sensitive  to  short-term  economic
     pressures.

FUND PERFORMANCE AND FEE INFORMATION

            Because  the  UltraSector  ProFunds  are  newly  formed  and have no
investment  track  record,  they have no  performance  to compare  against other

                      FUND INFORMATION -- UTILITIES PROFUND

FUND STRATEGY

ICON The investment objective of the Utilities ProFund is capital  appreciation.
The  Utilities  ProFund  seeks to achieve its  objective by creating  investment
exposure  approximating  twice its net assets to the  equities of the  companies
within the utilities sector.

PORTFOLIO INVESTMENTS

ICON The Utilities  ProFund  invests  substantially  all of its assets in equity
securities of Utility  Companies that are traded in the United  States.  Utility
Companies may include,  for example,  companies  involved in the  manufacturing,
production, generation,  transmission,  distribution or sales of gas or electric
energy;  water supply,  waste and sewage disposal;  and companies that receive a
majority of their  revenues from their public  utility  operations.  The Utility
ProFund  may also engage in futures,  options  and swaps  transactions  or other
financial  instruments,  which would allow the Utilities ProFund to leverage its
exposure to the utility sector,  purchase ADRs and U.S.  Government  securities,
and enter into repurchase agreements.

RISK CONSIDERATIONS

ICON The Utilities  ProFund is subject to a number of risks that will affect the
value of its shares, including:

 .    Utilities  Sector  Concentration  Risk -- The  securities of issuers in the
     utilities sector that the Utilities  ProFund purchases may underperform the
     market  as a whole.  To the  extent  that  the  ProFund's  investments  are
     concentrated in issuers  conducting  business in the same economic  sector,
     the Utilities  ProFund is subject to  legislative  or  regulatory  changes,
     adverse  market  conditions  and/or  increased  competition  affecting that
     economic  sector.  The prices of the securities of Utilities  Companies may
     fluctuate widely due to government regulation; the effect of interest rates
     on capital  financing;  competitive  pressures due to  deregulation  in the
     utilities industry;  supply and demand for services;  increased sensitivity
     to the cost of  natural  resources  required  for  energy  production;  and
     environmental factors such as conservation of natural resources.

redemptions  under  $5,000.  This charge may be waived at the  discretion of the
Utilities ProFund.

EXAMPLES

           The  following  examples  illustrate  the  expenses  you  would  have
incurred on a $10,000 investment in the Utilities  ProFund,  and are intended to
help you compare the cost of  investing  in the  Utilities  ProFund  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  the
Utilities  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.

                          ULTRASECTOR PROFUNDS STRATEGY

The Advisor uses  quantitative  analysis in seeking to achieve each  UltraSector
ProFund's investment objective.  This analysis determines the type, quantity and
mix  of  investment  positions  that  an  UltraSector  ProFund  should  hold  to
approximate the performance of its benchmark.

The UltraSector  ProFunds may invest in stocks that the Advisor  believes should
stimulate  the movement of the  applicable  economic  sector.  In addition,  the
UltraSector 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 option 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 value of an UltraSector ProFund's investments.

What the UltraSector ProFunds Do

Each UltraSector 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 UltraSector ProFunds Do Not Do

The Advisor does not:

 .    Conduct  conventional  stock  research or analysis or forecast stock market
     movement in managing the UltraSector ProFunds' assets.
 .    Invest the UltraSector  ProFunds' assets in stocks or instruments  based on
     the Advisor's 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 UltraSectors ProFunds' benchmarks over
     a period of time other than  daily,  such as  monthly  or  annually,  since
     mathematical  compounding  prevents the UltraSector ProFunds from achieving
     such results.



<PAGE>

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

The Advisor expects a significant portion of the UltraSector ProFunds' assets to
come from  professional  money  managers and investors  who use the  UltraSector
ProFunds as part of "market  timing"  investment  strategies.  These  strategies
often call for frequent trading of UltraSector  ProFund shares to take advantage
of anticipated  changes in market conditions.  Although the UltraSector  ProFund
Advisor  believes its accounting  methodology  should minimize the effect on the
UltraSector  ProFunds of such trading,  market timing trading could increase the
rate  of  UltraSector  ProFunds'  portfolio  turnover,  forcing  realization  of
substantial  capital gains and losses and increasing  transaction  expenses.  In
addition,  while the  UltraSector  ProFunds do not expect it, large movements of
assets into and out of the  UltraSector  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 UltraSector ProFunds' Share Prices

Each UltraSector  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 an  UltraSector  ProFund  are traded in markets on days when the
UltraSector  ProFund's  principal trading  market(s) is closed,  the UltraSector
ProFund's  net asset value may vary on days when  investors  cannot  purchase or
redeem shares.


<PAGE>

The  UltraSector  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
UltraSector  ProFunds  use the  following  methods  for  arriving at the current
market  price of  investments  held by the  UltraSector  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.
 .    foreign exchange values used to calculate net asset values will be the mean
     of the bid price and the asked price for the  respective  foreign  currency
     occurring immediately before the NYSE closes.

When price  quotes are not readily  available,  securities  and other assets are
valued at fair value in good faith under  procedures  established  by, and under
the general  supervision  and  responsibility  of, the 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  UltraSector  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 UltraSector ProFunds intends to distribute to its shareholders every
year all of the  year's  net  investment  income  and net  capital  gains.  Each
UltraSector  ProFund will reinvest  these  distributions  in  additional  shares
unless a shareholder has written to request a direct cash distribution.

Tax Consequences

An UltraSector  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 UltraSector  ProFund shares and regardless
of whether  distributions and dividends are reinvested or they choose to receive
cash.  Distributions and dividends  generally will be taxable as either ordinary
income or long-term  capital  gains.  For  example,  if an  UltraSector  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.
<PAGE>

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

If shareholders sell or redeem their UltraSector 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  UltraSector  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 an UltraSector 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 UltraSector ProFund.
 .    Dividends and distributions  declared by an UltraSector ProFund in October,
     November  or  December of one year and paid in January of the next year may
     be taxable in the year the UltraSector ProFund declared them.
 .    As with all  mutual  funds,  an  UltraSector  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  UltraSector  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 UltraSector  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,  the  Advisor  recommends
          that  shareholders  consult their tax advisors about  federal,  state,
          local and foreign tax  consequences  of investment in the  UltraSector
          ProFunds.

Classes of Shares

Each of the UltraSector ProFunds offer two classes of shares,  Investor Class of
shares,  and Service  Class of shares.  Investors 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 UltraSector 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,
 .    performing the accounting for the shareholder's account,
 .    maintaining  retirement  plan  accounts,  o  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 an UltraSector 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.

 .    The  UltraSector  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
     ProFunds under the procedures described above and (ii) the ProFunds receive
     and accept your wire. The UltraSector ProFunds can only accept wires during
     the times they process wires: between 8:00 a.m. and 3:30 p.m., Eastern time

     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 an UltraSector  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

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

The ProFunds' Prospectus is readily available for viewing on the website.

The ProFunds may terminate the ability to exchange ProFund shares on its website
at any time,  in which case you may  continue  to exchange  shares as  otherwise
provided in this Prospectus.

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.
 .    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 UltraSector  ProFunds described in

     review the prospectus related to the other ProFund.  Such prospectus may be
     obtained by  contacting  the ProFunds by letter or telephone at the address

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  UltraSector  ProFunds'

     guarantor  institution  such as a commercial bank, an NASD member firm such
     as a stock broker, a savings association or a national securities exchange.

Please keep in mind when redeeming shares:
 .    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  UltraSector  ProFund.  For
     redemption  of  shares  purchased  by check or  Automatic  Investment,  the
     UltraSector  ProFunds  may  wait up to 15 days  before  sending  redemption
     proceeds to assure  that the  transfer  agent has  collected  the  purchase
     payment.
 .    The UltraSector  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 UltraSector ProFunds to request a retirement
     distribution form.
 .    Involuntary  Redemptions:  The  UltraSector  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
     UltraSector 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.
<PAGE>

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
UltraSector 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.

Other Service Providers

BISYS Fund Services,  located at 3435 Stelzer Road, Suite 1000,  Columbus,  Ohio
43219,  acts  as  the  administrator  to  the  UltraSector  ProFunds,  providing
operations,  compliance and administrative  services.  Each UltraSector  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 UltraSector  ProFunds.  Each UltraSector  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 UltraSector
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  UltraSector
ProFunds  invest,  which could  impact the prices of the  UltraSector  ProFunds'
shares.

The  UltraSector  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  UltraSector  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 UltraSector 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 UltraSector  ProFunds'  service  providers
cannot be accurately  assessed at this time, the UltraSector  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 UltraSector  ProFunds
will continue to closely monitor developments relating to this issue.

     This  Statement of  Additional  Information  describes  the 17  UltraSector
ProFunds,  which are the  Banking  ProFund,  the Basic  Materials  ProFund,  the
Biotechnology  ProFund,  the Consumer Products ProFund, the Electronics ProFund,
the Energy ProFund, the Energy Services ProFund, the Financial Services ProFund,
the Health Care ProFund, the Internet ProFund, the Leisure ProFund, the Precious
Metals   ProFund,   the  Retailing   ProFund,   the  Technology   ProFund,   the
Telecommunications  ProFund,  the  Transportation  ProFund,  and  the  Utilities
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.  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

                                    PROFUNDS

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

                       INVESTMENT POLICIES AND TECHNIQUES

GENERAL

     Reference  is made to the  Prospectus  for a discussion  of the  investment
objectives and policies of the ProFunds. In addition, set forth below is further
information  relating to the ProFunds.  The  discussion  below  supplements  and
should be read in  conjunction  with the  Prospectus.  Portfolio  management  is
provided to the ProFunds by its  investment  adviser,  ProFund  Advisors  LLC, a
Maryland limited liability  company with offices at 7900 Wisconsin  Avenue,  NW,
Bethesda, Maryland (the "Advisor").

     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.

     It is the policy of the ProFunds to pursue their investment  objectives and
investment  stategies  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.

                       INVESTMENT OBJECTIVES AND POLICIES

     The investment  objectives and general  investment  polices of each ProFund
are  described  in  the  Prospectus.   Additional   information  concerning  the
characteristics of the ProFunds' investments is set forth below.

     Each  ProFund  seeks  to  achieve  its  investment  objective  by  creating
investment  exposure  within a specific  economic  sector equal to  aproximately
twice its net assets.  This is accomplished by leveraging the portfolio  through
the  utilization  of futures  contracts,  options,  swaps,  and other  financial
instruments. The combination of sector specific funds, combined with leveraging,
increases the volatility of the ProFunds.
<PAGE>

EQUITY SECURITIES

     Each ProFund may invest in equity  securities of companies that the Advisor
believes will experience  relatively rapid earnings growth.  The market price of
securities  owned  by a  ProFund  may  go  up  or  down,  sometimes  rapidly  or
unpredictably.  Securities  may  decline  in  value  due  to  factors  affecting
securities  markets  generally  or  particular  industries  represented  in  the
securities  markets.  The value of a security may decline due to general  market
conditions whch are not specifically  related to a particular  company,  such as
real or perceived  adverse economic  conditions,  changes in the general outlook
for  corporate  earnings,  changes in  interest or  currency  rates,  or adverse
investor sentiment generally.  They may also decline due to factors which affect
a  particular  industry or  industries,  such as labor  shortages  or  increased
production costs and competitive  conditions within an industry.  The value of a
security may also decline for a number of reasons which  directly  relate to the
issuer,  such as management  performance,  financial leverage and reduced demand
for the issuer's  goods or services.  Equity  securities  generally have greater
price volatility than fixed income securities, and the ProFunds are particularly
sensitive to these market risks.

FOREIGN INVESTMENT RISK

     The  ProFunds may invest in  securities  of foreign  issuers,  the Precious
Metals ProFund may invest in securities traded principally in securities markets
outside the United States and/or  securities  denominated in foreign  currencies
(together,   "foreign  securities").   Investments  in  foreign  securities  may
experience  more  rapid  and  extreme  changes  in  value  than  investments  in
securities of U.S. issuers or securities that trade exclusively in U.S. markets.
The  securities  markets of many foreign  countries are  relatively  small,  and
foreign  securities  often trade with less  frequency  and volume than  domestic
securities  and are usually not subject to the same degree of regulation as U.S.
issuers.  Special U.S. tax considerations may apply to a ProFund's investment in
foreign securities.

CURRENCY RISK

     The  ProFunds,  and in  particular  the  Precious  Metals  ProFund,  may in
securities  that trade in, or receive  revenues in, foreign  currencies.  To the
extent  that a ProFund  does so, that  ProFund  will be subject to the risk that
those  currencies  will decline in value relative to the U.S.  dollar.  Currency
rates in foreign  countries  may fluctuate  significantly  over short periods of
time. ProFund assets which are denominated in foreign currencies may be devalued
against the U.S. dollar, resulting in a loss.

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.

     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.
<PAGE>



     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.

     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.
<PAGE>

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 of 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."

     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, a 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.

     A ProFund may invest in both sponsored and  unsponsored  ADRs.  Unsponsored
ADR programs are  organized  independently  and without the  cooperation  of the
issuer  of  the  underlying  securities.  As  a  result,  available  information
concerning  the issuers  may not be as current as 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.

     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 many of
its investments in short-term options and futures contracts,  which,  therefore,
are excluded for purposes of computing portfolio turnover.

SPECIAL CONSIDERATIONS

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

     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.
<PAGE>

     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.

     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.
<PAGE>

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

     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.

     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.

PROFUND ADVISORS LLC

     Under an investment  advisory  agreement  between the Trust and the Advisor
with respect to the ProFunds,  dated [ ], 2000,  each ProFund pays the Advisor a
fee at an annualized rate, based on its average daily net assets,  of 0.75%. The
Advisor manages the investment and the reinvestment of the assets of each of the
ProFunds,  in  accordance  with  the  investment   objectives,   policies,   and
limitations of each ProFund,  subject to the general  supervision and control of
Trustees and the officers of the Trust.  The Advisor bears all costs  associated
with providing  these advisory  services.  The Advisor,  from its own resources,
including  profits from advisory fees received from the ProFunds,  provided such
fees are legitimate and not excessive,  also may make payments to broker-dealers
and other  financial  institutions  for their  expenses in  connection  with the
distribution of ProFund shares.  The Advisor's address is 7900 Wisconsin Avenue,
Suite 300, Bethesda, Maryland 20814.

ADMINISTRATION, TRANSFER AGENT, FUND ACCOUNTING AGENT AND CUSTODIAN

     BISYS Fund Services Limited Partnership d/b/a BISYS Fund Services ("BISYS")

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.

     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.

     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 the ProFunds.  In the Trustees'  quarterly review of the
Plan and  Shareholder  Services  Agreements,  they will consider their continued
appropriateness and the level of compensation provided therein.

     The intent of the Plan and  Shareholder  Services  Agreements is to procure
quality shareholder services on behalf of ProFund shareholders;  in adopting the
Plan and Shareholder Services Agreements,  the Trustees considered the fact that
such  shareholder  services  may have the effect of  enhancing  distribution  of
ProFund  Service 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,

          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 forty  separately  managed series,  seventeen 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.

                                    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.
<PAGE>

     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).

     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.
<PAGE>

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).

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.
<PAGE>

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.

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.
<PAGE>

     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.

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 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
Prospectus is set forth in the Appendix to this SAI.

                              FINANCIAL STATEMENTS

                                   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.

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.

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.
<PAGE>

DESCRIPTION OF FITCH INVESTORS SERVICE'S COMMERCIAL PAPER RATINGS:

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

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

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

     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.

                                    PROFUNDS
           Establishment and Designation of Seventeen 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 create  having the  following  special and relative
rights:

         1.       The Funds shall be designated as follows:

                 Banking ProFund                  Basic Materials ProFund
                 Biotechnology ProFund            Consumer Products ProFund
                 Electronics ProFund              Energy ProFund
                 Energy Services ProFund          Financial Services ProFund
                 Health Care ProFund              Internet ProFund
                 Leisure ProFund                  Precious Metals ProFund
                 Retailing ProFund                Technology ProFund
                 Telecommunications ProFund       Transportation ProFund
                                                  Utilities 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
Rule 18f-2 under such Act, or any  successor  rule,  and in the  Declaration  of
Trust.
<PAGE>

         4. The assets and  liabilities of the Trust shall be allocated  among a
Fund and all other series of the Trust (collectively,  the "Funds") as set forth
in the Declaration of Trust, except as described below.

         (a)      Costs  incurred by the Trust on behalf of a Fund in connection
                  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
                  the lesser of the life of each such Fund or such other  period
                  as required by applicable law.

         (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.

         IN WITNESS WHEREOF, the undersigned have executed this instrument as of
the date set forth below.

Registration  Statement of the Trust,  applicable provisions of the 1940 Act and
the rules and regulations  promulgated  thereunder and other applicable  federal
securities laws and regulations.
<PAGE>

2.  DUTIES OF ADVISOR

         Advisor shall provide a continuous program of investment management for
each  Portfolio.  Subject to the general  supervision  of the  Trust's  Board of
Trustees,  Advisor  shall have sole  investment  discretion  with respect to the
Portfolios,  including  investment  research,  selection of the securities to be
purchased and sold and the portion of the assets of each Portfolio, if any, that
shall be held  uninvested,  and the  selection of  broker-dealers  through which
securities transactions in the Portfolios will be executed. Advisor shall manage
the Portfolios in accordance with the  objectives,  policies and limitations set
forth in the Trust's current Prospectus and Statement of Additional Information.
Specifically,  and without  limiting the  generality of the  foregoing,  Advisor
agrees that it will:

                  (a) promptly advise each Portfolio's designated custodian bank
         and administrator or accounting agent of each purchase and sale, as the
         case may be, made on behalf of the  Portfolio,  specifying the name and
         quantity of the  security  purchased  or sold,  the unit and  aggregate
         purchase  or sale  price,  commission  paid,  the  market  on which the
         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.

                  The  Trust  shall  be  responsible  for all its  expenses  and

         Trustees who are not affiliated with the Portfolios'  Administrator  or

         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.

         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.

                              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

Retailing   ProFund,    Technology    ProFund,    Telecommunications    ProFund,
Transportation  ProFund, and the Utilities 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.
