                           Message From Your Chairman
 
Dear Shareholders:
 
  I am very pleased to present the Annual Report to the Shareholders of
ProFunds for the twelve months ended December 31, 1998. This, our first full
year in operation (ProFunds started in November of 1997), has been one of
tremendous success. Over the course of twelve months, net assets in ProFunds
increased from about $12 million at the beginning of 1998 to over $500 million
by year's end.
 
  UltraOTC ProFund was the best performing diversified U.S. stock fund in the
country according to Morningstar*, beating out all other funds in this
category, including those offered by the investment companies with household
names and large advertising budgets.
 
ProFunds Concept Succeeds . . .
 
  The success of the ProFunds concept has been very gratifying. ProFunds
started with the notion that conventional index funds were overly restrictive
to their shareholders--affording investors the limited ability to target a
return equal to the index and earn profit only in rising markets while
restricting their flexibility to adjust their portfolio based on current market
conditions. ProFunds set out to change this. 1998 helped prove this change was
needed.
 
  Throughout the year, our portfolios won high marks as they consistently
delivered excellent tracking with their benchmarks. Each ProFund had a
statistical correlation of at least .98. Thus, we believe our shareholders
received the performance they expected from ProFunds.
 
  Part of ProFunds concept is to extend the welcome mat for both long-term,
buy-and-hold investors and investors with shorter-term horizons--and give them
the flexibility to change their ProFund investment whenever their investment
outlook changes. ProFunds afforded both types of investors tremendous
investment opportunities in 1998.
 
  For example, #1 performing UltraOTC ProFund (Investor Class) produced a total
return of 185.34% for the twelve months ended December 31, 1998.** For short-
term investors and those who were hedging their portfolio, the July/August
correction when the S&P 500 fell 19% caused the UltraBear ProFund to soar 51%
in value.
 
  Not surprisingly, this type of performance and ProFunds' innovations
attracted an enormous amount of attention from the traditional print and
broadcast media as well as from the new electronic media. Just focusing on
November, December, and January, publications ranging from USA Today (11/27/98,
and 1/6/99) and the Wall Street Journal (12/2/98 and 1/7/99) to CBS
MarketWatch.com (12/3/98) and SmartMoney.com (12/30/98) covered the progress of
the ProFunds.
 
  On January 12, 1999, Dr. William Seale, our Director of Portfolio, was
interviewed on CNBC about the performance of the ProFunds in general, and that
of the UltraOTC Fund specifically. All of this press, we're delighted to
report, succeeded in greatly enhancing the visibility of the ProFunds and help
to contribute to the substantial growth in net assets under management.
 
A Focus On Service . . .
 
  With ProFunds' tremendous growth in assets in 1998, we recognize the need to
expand and upgrade our service capacity and options. We are hiring numerous
ProFund Service Representatives and adding many more phone lines to keep up
with the large volume of phone calls we are receiving each day. We also intend
to use technology to enhance our service to you. We expect to implement an
internet-based account information and transaction system and augment our
telephone response system to offer transactions. Our web site
 
                                       1
<PAGE>
 
(www.profunds.com) will be frequently enhanced to provide more current
information about ProFunds.
 
New ProFunds to track European Market . . .
 
  In the months ahead, we hope to build on our success and continue to develop
innovative investment vehicles that you our shareholders asked for so that they
can pursue their investment strategies. To this end, this Spring, we plan to
introduce two new funds to track equity activity in Europe: UltraEurope ProFund
will seek to double the return of a ProFunds-created European index and
UltraShort Europe ProFund will be designed to produce investment returns of
twice the inverse performance of the ProFunds Europe Index.
 
  As with the rest of our portfolios, these ProFunds will charge no transaction
fees. Nor will there be any restrictions on exchanges between these ProFunds.
Also, like the rest of the ProFunds family, we expect that these new funds will
be available through all major mutual fund platforms and discount brokers. Or
you may contact us directly by phone for a prospectus or visit us at
www.profunds.com.
 
In closing . . .
 
  We deeply appreciate your confidence and support. Going forward, we will
continue to strive to be worthy of it by providing you, and all our
shareholders, with ProFunds that provide you with the investment tools you need
and the services you require. As always, if you have any questions or require
any assistance, please don't hesitate to call us. Financial Professionals can
reach us at 1-888-PRO-5717 (1-888-776-5717). All other shareholders please call
1-888-PRO-FNDS (1-888-776-3637) or (614) 470-8122.
 
Sincerely,

                      Message From Your Investment Advisor
Dear Shareholders:
 
  The stock markets were more volatile over the twelve months ended December
31, 1998 than they were in any year during the last decade. If global economic,
political and financial turmoil, and profitless prosperity for certain sectors
of the economy were not enough to occupy investors' minds, they had two other
unusual events to ponder: the possible impeachment of President Clinton and the
financial situation in Asia. Throughout much of the first half of the year, an
amazingly resilient U.S. bull market seemed able to overlook both of these
situations. Many investors were anxious about the markets' increased volatility
but on the upside, in mid-July, both the S&P 500 and the Nasdaq 100 reached
record levels. Shortly thereafter, however, they began to ease down. In August,
the atmosphere continued to chill on news that the Russian economy was in far
worse shape than previously suspected and the fact that no viable solutions to
Japan's economic problems were at hand.
 
  The fate of Russia and its economy has had only minimal impact on the global
economy. However the psychological impact of the deterioration in world
economic conditions in mid-summer, Japan's continued economic woes and concerns
caused by the failure of the hedge fund, Long Term Capital Management, were a
potent combination and investors became more concerned. This caused the markets
to slide significantly. For example, from its high of 1,190 in July, the S&P
500 fell to a low of 923 in early October. The Nasdaq 100 fell from its high of
1,486 to a low of 1,063 during the same period.
 
Upward Momentum Wins Out
 
  In September, however, signs that many of the situations that had triggered
the markets' decline were beginning to ease. In Asia, structural economic
reforms were under consideration. Japanese regulators were proposing serious
banking reforms. In Latin America, the Brazilians were moving towards austerity
budgeting with the help of the IMF. Noting that financial conditions at home
had become less friendly to growth, the Federal Reserve made the first of three
cuts in short-term interest rates.
 
  With these indications that some of the global economic problems were being
addressed rather than ignored, investors grew more confident and investors
began to move back into the marketplace. The downward trend reversed in mid-
October. Over the next two months the stock markets recovered to their mid-
summer levels and then, moved higher. Technology stocks were the undisputed
leaders and the sheer momentum of this group of stocks moved the market higher
in the latter part of 1998. By the end of December, the Nasdaq 100 had gained
85% for the year and our UltraOTC fund was up 185% for the year.
 
European Union Creates Opportunity
 
  On January 1, 1999, the European Union introduced the Euro and the launch was
successful. As we go to press, the Europeans now have the first common currency
since the fall of the Roman Empire. It is anticipated that the elimination of
intra-European exchange rate uncertainty will make the region a far easier
place to do business and it should make Europe a much more efficient investment
venue.
 
  In short, while complete European monetary unification is years off, the
adoption of the Euro makes it possible for investors to more efficiently track
the progress of EC financial markets. However, while the integration of the
individual European currencies isn't without potential peril, today, taken as a
whole, Europe nearly equals the United States in sheer economic weight. The EC
has a population of nearly 290 million and a Gross Domestic Product that is 80%
of the U. S. The eleven member nations of the EC account for 19% of world trade
versus 17% for the United States. In this light, we look forward to introducing
our new "bull" and "bear" ProFunds focusing on the combination of the three
largest capitalization European stock markets: London, Paris, and Frankfurt.
 
Sincerely,
 
 
William E. Seale, Ph.D.
Director of Portfolio

                               The Bull ProFund
 
 
  The Bull ProFund seeks to provide daily investment returns that correspond
to the performance of the S&P 500 Index. Over the course of the year ended
December 31, 1998, this benchmark gained 258.78 points which the Fund's
performance tracked with a statistical correlation of .98. As a result, for
the twelve months, the Fund (Investor Shares) produced a total return of
26.57%* versus a return of 26.67% for the S&P 500.

  The performance of the Bull ProFund is measured against the S&P 500 Index,
an unmanaged index generally representative of the performance of the U.S.
stock market as a whole. The index does not reflect reinvestment of dividends
or the deduction of expenses associated with a mutual fund, such as investment
management and accounting fees. The Fund's performance reflects the deduction
of these value-added services.

                                The Bear ProFund
  The Bear ProFund's investment objective is to provide daily investment
results that inversely correlate to the performance of the S&P 500 Index. Over
the twelve months, the Fund's performance tracked this benchmark with a
statistical correlation of .99. Consequently, in the July/August correction,
the Fund (Investor Shares) produced a total return of 21.0% versus a return of
- -17.9% over the same period for the S&P 500. Over the course of the year,
however, the Index gained 258.78 points and generated a return of 26.67%. The
Fund (Investor Shares), as anticipated, posted a total return of -19.46% for
the same period.*

  The performance of the Bear ProFund is measured against the S&P 500 Index, an
unmanaged index generally representative of the performance of the U.S. stock
market as a whole. The index does not reflect reinvestment of dividends or the
deduction of expenses associated with a mutual fund, such as investment
management and accounting fees. The Fund's performance reflects the deduction
of these value-added services.

                             The UltraBear ProFund
  The UltraBear ProFund's investment objective is to provide daily investment
results that inversely correlate to 200% of the performance of the S&P 500
Index. Over the twelve months, the Fund's performance tracked this benchmark
with a statistical correlation of .98. Consequently, in the July/August
correction, the Fund (Investor Shares) produced a total return of 43.6% versus
a return of -17.9% over the same period for the S&P 500. Over the course of the
year, however, the index gained 2587.78 points and generated a return of
26.67%. The Fund (Investor Shares), as anticipated, posted a total return of -
38.34% for the same period.*

  The performance of the UltraBear ProFund is measured against the S&P 500
Index, an unmanaged index generally representative of the performance of the
U.S. stock market as a whole. The index does not reflect reinvestment of
dividends or the deduction of expenses associated with a mutual fund, such as
investment management and accounting fees. The Fund's performance reflects the
deduction of these value-added services.

                           The UltraShort OTC ProFund
  The investment objective of the UltraShort OTC ProFund is to provide daily
investment results that correspond to twice of the inverse (opposite) of the
performance of the NASDAQ 100 Index. The NASDAQ 100 includes 100 of the largest
non-financial domestic companies listed on the NASDAQ National Market tier of
the NASDAQ Stock Market. Over the twelve months, the Fund's performance tracked
this benchmark with a statistical correlation of .99. Consequently, in the
July/August correction, the Fund (Investor Shares) produced a total return of
38.4% versus a return of -17.0% over the same period for the NASDAQ 100. Over
the course of the year, however, the Index gained 845.16 points and generated a
return of 85.30%. The Fund (Investor Shares), as anticipated, posted a total
return of -67.48% since it began trading June 2, 1998.*

  The performance of the UltraShort OTC ProFund is measured against the NASDAQ
100 Index, an unmanaged index generally representative of the performance of
NASDAQ stock market as a whole. The index does not reflect reinvestment of
dividends or the deduction of expenses associated with a mutual fund, such as
investment management and accounting fees. The Fund's performance reflects the
deduction of these value-added services.

                            The Money Market ProFund
 
  The Money Market ProFund seeks, as its investment objective, a high level of
current income consistent with liquidity and preservation of capital. For the
year ended December 31, 1998 the Fund (Investor Class) returned 4.84%.
 
  The assets of this fund are part of a $4.5 billion portfolio managed by
Bankers Trust company. Its managers seek to maintain a stable net asset value
of $1.00, there is no assurance that they will be able to do so. An investment
in the Fund is neither guaranteed nor insured by the FDIC or any other
government agency. Although the Fund strives to maintain the value of your
investment at $1.00 per share, it is possible to lose money by investing in
this Fund.
 
* Past performance is not predictive of future results. The investment return
  and NAV will fluctuate so that the investor's shares, when redeemed, may be
  worth more or less than the original cost.

                         Notes to Financial Statements
                               December 31, 1998
 
1.Organization
 
  ProFunds (the "Trust") is a registered open-end investment company under the
  Investment Company Act of 1940 (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. ProFunds Advisors LLC (the "Advisor")
  serves as the investment advisor for each of the ProFunds except the Money
  Market ProFund. BISYS Fund Services Limited Partnership ("BISYS"), a wholly
  owned subsidiary of The BISYS Group, Inc., acts as the Trust's
  administrator. Currently, the Trust consists of seven separately managed
  series: Bull ProFund, UltraBull ProFund, UltraOTC ProFund, Bear ProFund,
  UltraBear ProFund, UltraShort OTC ProFund, and Money Market ProFund
  (collectively the "ProFunds" and individually, a "ProFund"). The ProFunds,
  excluding the Money Market ProFund, are referred to as the "non-money market
  ProFunds". Each ProFund offers two classes of shares: the Service Shares and
  the Investor Shares.
 
  The investment objectives of the ProFunds are as follows:
 
  The Bull ProFund and the UltraBull ProFund. The Bull ProFund's investment
  objective is to provide investment returns that correspond to the
  performance of the S&P 500 Index. The UltraBull ProFund's investment
  objective is to provide investment returns that correspond to 200% of the
  performance of the S&P 500 Index. The UltraBull ProFund should gain more
  than the Bull ProFund when the prices of the securities in the S&P 500 Index
  rise and lose more when such prices decline.
 
  The Bear ProFund and the UltraBear ProFund. The Bear ProFund's investment
  objective is to provide investment results that will inversely correlate to
  the performance of the S&P 500 Index. The UltraBear ProFund's investment
  objective is to provide investment results that will inversely correlate to
  200% of the performance of the S&P 500 Index.
 
  If the Bear ProFund is successful in meeting its objective, the net asset
  value of Bear ProFund shares will increase in direct proportion to any
  decrease in the level of the S&P 500 Index. Conversely, the net asset value
  of Bear ProFund shares will decrease in direct proportion to any increases
  in the level of the S&P 500 Index. The percentage change of net asset value
  of shares of the UltraBear ProFund should increase or decrease approximately
  twice as much as does that of the Bear ProFund on any given day.
 
  The UltraOTC ProFund and the UltraShort OTC ProFund. The investment
  objective of the UltraOTC ProFund is to provide investment results that
  correspond to 200% of the performance of the NASDAQ 100 Index. The NASDAQ
  100 Index includes 100 of the largest non-financial domestic companies
  listed on the NASDAQ National Market tier of The NASDAQ Stock Market. The
  UltraShort Profund seeks investment results that correspond each day to
  twice of the inverse (opposite) of the performance of the NASDAQ 100 Index.
  It is the policy of the UltraShort OTC Profund to pursue its investment
  objective of correlating with its benchmark regardless of market conditions,
  to remain fully invested and to not take defensive positions.
 
  If the UltraShort OTC Profund achieved a perfect inverse correlation for any
  single trading day, the net asset value of the shares of this ProFund would
  increase for that day proportional to twice any decrease in the level of the
  NASDAQ 100 Index. Conversely, the net asset value of the shares of the
  ProFund would decrease for that day proportional to twice any increase in
  the level of the NASDAQ 100 Index for that day. The percentage change of net
  asset value of shares of the UltraOTC ProFund should increase or decrease
  approximately twice as much as does that of the UltraShort ProFund on any
  given day.
 
  The Money Market ProFund. The Money Market ProFund seeks, as its investment
  objective, a high level of current income consistent with liquidity and
  preservation of capital. To achieve its objective, the Money Market ProFund
  invests all of its investable assets in the Cash Management Portfolio
  ("Portfolio"), which has the same investment objective as the Money Market
  ProFund.
 
  The performance of the Money Market ProFund is directly affected by the
  performance of the Portfolio. The financial statements of the Portfolio,
  including its schedule of investments, are included elsewhere within this
  report and should be read in conjunction with the Money Market ProFund's
  financial statements.
 
2.Significant Accounting Policies
 
  The following is a summary of significant accounting policies consistently
  followed by each ProFund in preparation of its financial statements. These
  policies are in conformity with generally accepted accounting principles.
  The preparation of financial statements in accordance with generally
  accepted accounting principles requires management to make estimates and
  assumptions that effect the reported amount of assets and liabilities and
  disclosure of contingent assets and liabilities at the date of the financial
  statements and the reported amounts of income and expense during the
  reporting period. The actual results could differ from those estimates.

                   Notes to Financial Statements, Continued
                               December 31, 1998
 
 
  a) Investment Valuation
 
  The securities, except as otherwise noted, in the portfolio of a non-money
  market ProFund that are listed or traded on a stock exchange, are valued on
  the basis of the closing price on that day or, lacking any sales, at a price
  that is the mean between the closing bid and asked prices. Other securities
  that are traded on the OTC markets are priced using NASDAQ, which provides
  information on bid and asked prices quoted by major dealers in such stocks.
  Bonds, other than convertible bonds, are valued using a third-party pricing
  system. Convertible bonds are valued using this pricing system only on days
  when there is no sale reported. Short-term debt securities are valued at
  amortized cost, which approximates market value.
 
  Futures contracts purchased and held by the ProFunds are valued at the last
  sale price immediately prior to the 4:00pm Eastern Time price on the futures
  exchanges on which they are traded. Conversely, the value of a futures
  contract sold by ProFunds will be either the last sale price or the asked
  price. Options on securities and indices purchased or sold by a ProFund are
  valued at their last sale price. In the event market quotations are not
  readily available, securities, futures contracts, options and other assets
  are valued at fair value as determined in good faith under procedures
  established by and under general supervision and responsibility of the
  ProFund's Board of Trustees.
 
  Valuation of securities held by the Portfolio is discussed in Note 1 of the
  notes to financial statements of the Portfolio, which are included elsewhere
  in this report.
 
  b) Repurchase Agreements
 
  Under a repurchase agreement, a ProFund purchases a debt security and
  simultaneously agrees to sell the security back to the seller at a mutually
  agreed-upon future price and date, normally one day or a few days later. The
  resale price is greater than the purchase price, reflecting an agreed-upon
  market interest rate during the purchaser's holding period. While the
  maturities of the underlying securities in repurchase transactions may be
  more than one year, the term of each repurchase agreement will always be
  less than one year. A ProFund will enter into repurchase agreements only
  with member banks of the Federal Reserve System or primary dealers of U.S.
  government securities. The Advisor and, with respect to the Portfolio,
  Bankers Trust, will monitor the creditworthiness of each of the firms which
  is a party to a repurchase agreement with any of the ProFunds.
 
  The ProFunds require that the securities purchased in a repurchase agreement
  transaction be transferred to the custodian in a manner sufficient to enable
  the ProFund to obtain those securities in the event of a counterparty
  default. The seller, under the repurchase agreement, is required to maintain
  the value of the securities held at not less than the repurchase price,
  including accrued interest. Repurchase agreements are considered to be loans
  under the 1940 Act.
 
  c) Federal Income Tax
 
  Each of the ProFunds intends to qualify each year as a regulated investment
  company (a "RIC") under Subchapter M of the Internal Revenue Code of 1986,
  as amended. A RIC generally is not subject to federal income tax on income
  and gains distributed in a timely manner to its shareholders; the ProFunds
  intend to make timely distributions in order to avoid tax liability.
 
  d) Securities Transactions and Related Income
 
  Securities transactions are accounted for on the date the security is
  purchased or sold (trade date). Interest income is recognized on the accrual
  basis and includes, where applicable, the pro rata amortization of premium
  or discount. Dividend income is recorded on the ex-dividend date. Gains or
  losses realized on sales of securities are determined by comparing the
  identified cost of the security lot sold with the net sales proceeds.
 
  e) Expenses
 
  Expenses directly attributable to a ProFund are charged to the ProFund,
  while expenses which are attributable to more than one ProFund are allocated
  among the respective Profunds based upon relative net assets or another
  appropriate basis. In addition, investors in Investor Shares will pay the
  expenses directly attributable to the Investor Shares as a class, and
  investors in Service Shares will pay the expenses directly attributable to
  the Service Shares as a class.
 
  The investment income and expenses of a ProFund (other than class specific
  expenses) and realized and unrealized gains and losses on investments of a
  ProFund, are allocated to each class of shares based upon relative net
  assets on the date income is earned or expenses are realized and unrealized
  gains and losses are incurred.
 
  f) Distributions to Shareholders
 
  The non-money market ProFunds will distribute net investment income and net
  realized gains, if any, at least once a year. The Money Market ProFund
  ordinarily (i) declares dividends of net investment income (and net short-
  term capital gains, if any) for
                                   Continued

  shares of the Money Market ProFund on a daily basis and (ii) distributes
  such dividends to shareholders of the Money Market ProFund on a monthly
  basis. Net realized capital gains, if any, will be distributed annually.
 
  The amount of distributions from net investment income and net realized
  gains are determined in accordance with federal income tax regulations which
  may differ from generally accepted accounting principles. These "book/tax"
  differences are either considered temporary or permanent in nature. To the
  extent these differences are permanent in nature, such amounts are
  reclassified within the composition of net assets based on their federal
  tax-basis treatment; temporary differences do not require a
  reclassification. Distributions which exceed net investment income and net
  realized capital gains for financial reporting purposes but not for tax
  purposes are reported as distributions in excess of net investment income or
  net realized gains. To the extent they exceed net investment income and net
  realized capital gains for tax purposes, they are reported as distribution
  of capital. The non-money market ProFunds utilize equalization accounting
  for tax purposes and designate earnings and profits, including net realized
  gains distributed to shareholders on redemption of shares, as a part of the
  dividends paid deduction for income tax purposes.
 
  As of December 31, 1998, the following reclassifications have been made to
  increase (decrease) such accounts with offsetting adjustments made to paid-
  in-capital:

  g) Capital Accounts
 
  The trust follows provisions of the AICPA's Statement of Position 93-2
  "Determination, Disclosure and Financial Statement Presentation of Income,
  Capital Gain and Return of Capital Distributions by Investment Companies"
  ("SOP"). The purpose of this SOP is to report undistributed net investment
  income and accumulated net realized gain or loss in such a manner as to
  approximate amounts available for future distributions to shareholders, if
  any.
 
  h) Short Sales
 
  When a ProFund engages in a short sale, the ProFund records a liability for
  securities sold short, and records an asset equal to the proceeds received.
  The amount of the liability is subsequently marked to market to reflect the
  market value of the short sale. The ProFund maintains a segregated account
  of securities as collateral for outstanding short sales, when required. The
  ProFund is exposed to market risk based on the amount, if any, that the
  market value of the securities sold short exceeds the proceeds received.
 
  i) Options
 
  When a ProFund writes (sells) an option, an amount equal to the premium
  received is entered in the ProFund's accounting records as an asset and
  equivalent liability. The amount of the liability is subsequently marked to
  market to reflect the current value of the option written. When an option
  expires, or if the ProFund enters into a closing purchase transaction, the
  ProFund realizes a gain (or loss if the cost of a closing purchase
  transaction exceeds the premium received when the option was sold).
 
  The following is a summary of written option activity for the year ended
  December 31, 1998, for the UltraBear ProFund.

  j) Futures Contracts
 
  The ProFunds may purchase or sell stock index futures contracts and options
  on such futures contracts. Futures contracts are contracts for delayed
  delivery of securities at a specified future delivery date and at a specific
  price. Upon entering into a contract, the ProFund may be required to deposit
  and maintain as collateral such initial margin as required by the exchange
  on which the transaction is effected. Pursuant to the contract, the ProFund
  agrees to receive from or pay to the broker an amount of cash equal to the
  daily fluctuation in value of the contract. Such receipts or payments are
  known as variation margin and are recorded by the ProFund as unrealized
  gains or losses. When the contract is closed or offset, the ProFund records
  a realized gain or loss equal to the difference between the value of the
  contract at the time it was opened and the value at the time it was closed.
 
  k) Risks of Futures Contracts and Options
 
  Futures contracts and written options involve, to varying degrees, elements
  of market risk and exposure to loss in excess of the amount recognized in
  the Statements of Assets and Liabilities. The face or contract amounts
  reflect the extent of the total exposure each ProFund has in the particular
  classes of instruments. Risks may result from an imperfect correlation
  between movements in the price of the instruments and the price of the
  underlying securities.
 
  l) Organization Costs
 
  Costs incurred by the Trust in connection with its organization have been
  deferred and are being amortized on the straight-line method over a five-
  year period beginning on the date on which each ProFund commenced its
  investment activities.
 
3.Shares of Beneficial Interest
 
  Transactions in shares of beneficial interest were as follows for the
  periods ended December 31, 1998 and December 31, 1997. (Non-money market
  ProFund shares have been adjusted to reflect the 5 for 1 reverse stock split
  that occurred on January 15, 1999.)

4.Investment Advisory Fees, Administration Fees and Other Related Party
Transactions
 
  The non-money market ProFunds have entered into an Investment Advisory
  Agreement with the Advisor. Under this agreement, dated October 28, 1997,
  the non-money market ProFunds each pay the Advisor a fee at an annualized
  rate, based on the average daily net assets of each respective ProFund, of
  0.75%.
 
  For its services as Administrator, each ProFund pays BISYS an annual fee
  ranging from 0.15% of average daily nets assets of $0 to $300 million to
  0.05% of average daily net assets of $1 billion and over. Concord Financial
  Group, Inc. an affiliate of BISYS, serves as the Trust's distributor and
  principal underwriter and receives no compensation from the ProFunds for
  such services. BISYS Fund Services, Inc. ("BFSI"), also an affiliate of
  BISYS, acts as transfer agent and fund accounting agent for the ProFunds,
  for which it receives additional fees. Additionally, ProFunds, 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. BISYS began charging for their services as
  of June 1, 1998.
 
  ProFunds Advisors LLC, pursuant to a separate Management Services Agreement,
  performs certain client support services and other administrative services
  on behalf of the ProFunds. For these services, each non-money market ProFund
  will pay to ProFunds Advisors LLC a fee at the annual rate of 0.15% of its
  average daily net assets. Under this agreement, ProFunds Advisors LLC may
  receive up to 0.35% of the Money Market ProFund's average daily net assets
  for providing feeder fund management and administrative services to the
  Money Market ProFund.
 
  Each ProFund has adopted a Shareholder Services Plan (the "Plan") and
  related agreement ("Shareholder Services Agreement"). The Plan provides that
  each ProFund will make payments to Authorized Firms in amount up to 1.00%
  (on an annual basis) of the average net assets of such ProFund's Service
  class of shares attributable to or held in the name of an Authorized Firm
  for its clients. The Plan provides that the fee will be paid to registered
  investment advisors, banks, trust companies and other financial
  organizations for providing account administration and other services to
  their clients who are beneficial owners of such shares.
 
  Certain Trustees of the Trust are Officers of ProFunds Advisors LLC and are
  compensated for such services.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Trustees and Shareholders of
ProFunds Trust
 
In our opinion, the accompanying statements of assets and liabilities,
including the schedules of portfolio investments, and the related statements
of operations and changes in net assets and the financial highlights present
fairly, in all material respects, the financial position of the ProFunds Trust
(comprising, respectively, the Bull ProFund, UltraBull ProFund, UltraOTC
ProFund, Bear ProFund, UltraBear ProFund, UltraShort OTC ProFund and Money
Market ProFund, hereafter referred to as the "Trust") at December 31, 1998,
the results of each of their operations, the changes in their net assets, and
the financial highlights for each of the periods presented, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Trust's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits, which included confirmation of securities at December 31, 1998 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

- --------------------------------------------------------------------------------

Note 1--Organization and Significant Accounting Policies.
A.  Organization
The Cash Management Portfolio (the "Portfolio") is registered under the
Investment Company Act of 1940 (the "Act"), as amended, as an open-end
management investment company. The Portfolio was organized on March 26, 1990, as
an unincorporated trust under the laws of New York, and commenced operations on
July 23, 1990. The Declaration of Trust permits the Board of Trustees (the
"Trustees") to issue beneficial interests in the Portfolio.

B.  Security Valuation
Investments are valued at amortized cost, which is in accordance with Rule 2a-7
of the Investment Company Act of 1940 and represents the fair value of the
Portfolio's investments.

C.  Security Transactions and Interest Income
Security transactions are accounted for on a trade date basis. Interest income
is recorded on the accrual basis and includes amortization of premium and
accretion of discount on investments. Realized gains and losses from securities
transactions are recorded on the identified cost basis.

All of the net investment income and realized and unrealized gains and losses
from the security transactions of the Portfolio are allocated pro rata among the
investors in the Portfolio at the time of such determination.

D.  Repurchase Agreements
The Portfolio may enter into repurchase agreements with financial institutions
deemed to be creditworthy by the Portfolio's' Investment Advisor, subject to the
seller's agreement to repurchase such securities at a mutually agreed upon
price. Securities purchased subject to repurchase agreements are deposited with
the Portfolio's custodian, and pursuant to the terms of the repurchase must have
an aggregate market value greater than or equal to the repurchase price plus
accrued interest at all times. If the value of the underlying securities falls
below the value of the repurchase price plus accrued interest, the Portfolio
will require the seller to deposit additional collateral by the next business
day. If the request for additional collateral is not met, or the seller defaults
on its repurchase obligation, the Portfolio maintains the right to sell the
underlying securities at market value and may claim any resulting loss against
the seller. However, in the event of a default or bankruptcy by the seller,
realization and/or retention of the collateral may be subject to legal
proceedings.

E.  Federal Income Taxes
The Portfolio is considered a partnership under the Internal Revenue Code.
Therefore, no federal income tax provision is required.

F.  Other
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts in the financial statements. Actual results could
differ from those estimates.

Note 2--Fees and Transactions with Affiliates
The Portfolio has entered into an Administration and Services Agreement with
Bankers Trust Company ("Bankers Trust"). Under this Administration and Services
Agreement, Bankers Trust provides administrative, custody, transfer agency and
shareholder services to the Portfolio in return for a fee computed daily and
paid monthly at an annual rate of .05% of the Portfolio's average daily net
assets. For the year ended December 31, 1998, administrative and service fees
amounted to $2,673,031, of which $249,048 was payable at the end of the period.

The Portfolio has entered into an Advisory Agreement with Bankers Trust. Under
this Advisory Agreement, the Portfolio pays Bankers Trust an advisory fee
computed daily and paid monthly at an annual rate of .15% of the Portfolio's
average daily net assets. For the year ended December 31, 1998, advisory fees
amounted to $8,019,093, of which $747,145 was payable at the end of the period.

Bankers Trust has voluntarily undertaken to waive its fees and reimburse
expenses of the Portfolio, to the extent necessary, to limit all expenses to
 .18% of the average daily net assets of the Portfolio.

In 1994, the Portfolio sold certain structured notes carried at par to an
unrelated third party financial institution at par plus accrued interest
pursuant to a put agreement and that third party financial institution
immediately resold such security to Bankers Trust New York Corporation, the
parent of the Advisor, at the same price, also pursuant to a put agreement. As a
result of these transactions the Portfolio's Financial Highlights for the year
ended December 31, 1994, reflects the Portfolio's realized loss on the sale of
these securities and a capital contribution in the amount of $18,718,663. In
1996, Bankers Trust contributed capital in the amount of $1,113,488 to reimburse
the Cash Management Portfolio for capital losses incurred in prior years.

The Cash Management Portfolio is a participant with other affiliated entities in
a revolving credit facility and a discretionary demand line of credit facility
(collectively the "credit facilities") in the amounts of $50,000,000 and
$100,000,000, respectively, which expire March 15, 1999. A commitment fee of
 .07% per annum on the average daily amount of the available commitment is
payable on a quarterly basis and apportioned equally among all participants.
Amounts borrowed under the credit facilities will bear interest at a rate per
annum equal to the Federal Funds Rate plus .45%. No amounts were drawn down or
outstanding under the credit facilities as of and for the year ended December
31, 1998.

Note 3--Net Assets
At December 31, 1998 net assets consisted of:

Paid-in-Capital                     $5,464,252,989
                                     =============

Report of Independent Accountants

To the Trustees and Holders of Beneficial Interest of
Cash Management Portfolio:

In our opinion, the accompanying statement of net assets and the related
statements of operations and of changes in net assets and the financial
highlights present fairly, in all material respects, the financial position of
Cash Management Portfolio (the "Portfolio") at December 31, 1998, and the
results of its operations, the changes in its net assets and the financial
highlights for each of the fiscal periods presented, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Portfolio's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 1998 by
correspondence with the custodian, provide a reasonable basis for the opinion
expressed above.
