                              ProFund Advisors LLC

<PAGE>

                                                        The ProFund VP UltraBull

The UltraBull VP Objective

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

Investment Strategy

The  investments  made by the  UltraBull  VP and  the  results  achieved  by the
UltraBull  VP at any given time are not expected to be the same as those made by
other mutual funds for which  ProFund  Advisors LLC  ("ProFund  Advisors"),  the
investment  advisor of the UltraBull VP, acts as investment  advisor,  including
mutual  funds with names,  investment  objectives  and  policies  similar to the
UltraBull VP.  Investors  should  carefully  consider their investment goals and
willingness to tolerate  investment risk before  allocating  their investment to
the UltraBull VP.

ProFund Advisors uses a "passive" approach to investing,  employing quantitative
analysis.  On the basis of this analysis,  ProFund Advisors determines the type,
quantity and mix of  investment  positions  that the UltraBull VP should hold to
approximate  the  performance  of its  benchmark  (200%  of the S&P 500  Index).
ProFund  Advisors  does not  make  judgments  about  the  investment  merit of a
particular stock, nor does it attempt to apply any economic, financial or market
analysis. The UltraBull VP does not take temporary defensive positions.

The UltraBull VP principally invests in:

 .    A combination of equity securities that in ProFund Advisors' opinion should
     simulate the movement of the appropriate benchmark index;

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

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

The  UltraBull  VP invests in futures  contracts  on stock  indexes,  options on
futures  contracts,  and  the  other  financial  instruments  noted  above  as a
substitute  for  investing  directly in stocks in order to gain  exposure to the
appropriate  benchmark  index.  The UltraBull VP generally  invests in the above
instruments to produce economically "leveraged" investment results.  Leverage is
a way to change small market  movements  into larger changes in the value of the
UltraBull VP's investments.

Investment Risks

Like all  investments,  investing  in the  UltraBull  VP entails  risk.  ProFund
Advisors cannot  guarantee that the UltraBull VP will achieve its objective.  As
with any mutual  fund,  the  UltraBull VP could lose money,  or its  performance
could trail that of other investment alternatives.
<PAGE>

In addition,  the UltraBull VP presents some risks not traditionally  associated
with most mutual  funds.  It is  important  that  investors  closely  review and
understand  these  risks  before  making an  investment.  The  UltraBull  VP, as
described  in greater  detail  below,  is  subject to market  risk and the risks
associated with the use of leveraging, among others.

Market Risk - The  UltraBull  VP is subject to market risks that will affect the
value of its shares,  including general economic and market conditions,  as well
as  developments  that impact  specific  industries or  companies.  Shareholders
should  lose  money  when  the S&P 500  Index  declines.  The S&P 500  Index  is
discussed in the next section.

Leverage Risk - The UltraBull VP employs leveraged investment techniques and may
borrow money for investment purposes. Leverage is the ability to get a return on
a  capital  base that is  larger  than the  UltraBull  VP's  investment.  Use of
leverage can magnify the effects of changes in the value of a fund and makes the
fund more volatile.  The leveraged  investment  techniques that the UltraBull VP
employs should subject investors in the UltraBull VP to approximately double the
potential  risk of loss of a  conventional  index  fund that  seeks to track the
performance of the same underlying index.

Correlation Risk - ProFund Advisors expects that the UltraBull VP will track its
benchmark with a high level of correlation.  There can be, however, no guarantee
that the UltraBull VP will be able to achieve a high level of correlation, since
the  ability of the  UltraBull  VP to track its  benchmark  may be  affected  by
numerous  factors.  The UltraBull VP may invest in securities or other financial
instruments not included in its underlying  index. The UltraBull VP may not have
investment  exposure to all securities in its underlying  index or its weighting
of investment  exposure to such stocks may be different  from that of the index.
Actual  purchases  and sales of the  shares  of the  UltraBull  VP by  insurance
company separate accounts may differ from estimated transactions reported to the
UltraBull VP by the insurance companies prior to the time the UltraBull VP share
prices are  calculated.  These factors may adversely  affect the performance and
the  correlation of the UltraBull VP with its benchmark.  A failure to achieve a
high degree of  correlation  may prevent the  UltraBull  VP from  achieving  its
investment goal.

Risks of Aggressive  Investment  Techniques - The  UltraBull VP uses  investment
techniques that may be considered  aggressive.  Risks associated with the use of
options,   swaps,  futures  contracts  and  other  similar  instruments  include
potentially  dramatic price changes (losses) in the value of the instruments and
imperfect  correlations  between the price of the  contract  and the  underlying
security or index.
<PAGE>

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

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

The UltraBull VP Benchmark Index


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

Who May Want to Consider an Investment

The UltraBull VP may be appropriate for investors who:

 .        believe  that over the long  term,  the value of the S&P 500 Index will
         increase,  and that by  investing  with the  objective  of doubling the
         Index's daily  return,  they will achieve  superior  results over time.
         Investors  in  the  UltraBull  VP  should  understand  that  since  the
         UltraBull  VP seeks to  double  the  daily  performance  of the S&P 500
         Index, it should have twice the volatility of a conventional index fund
         and twice the potential risk of loss.

 .        are  seeking to match the S&P 500  Index's  daily  return with half the
         investment  required of  conventional  stock index  mutual  funds.  For
         example,  an investor might invest  $100,000 in a conventional  S&P 500
         Index  fund,  or that same  investor  could  invest half that amount --
         $50,000 -- in the UltraBull VP and target the same daily return.

 .        are  executing  a  strategy  that  relies on frequent buying or selling
         among stock mutual funds.

The UltraBull VP's Performance

Because the UltraBull VP is newly formed and has no investment track record,  it
has no  performance  to compare  against other mutual funds or broad measures of
securities  market  performance,  such as an index.  However,  ProFund Advisors'
track record in managing a similar mutual fund is discussed  under "Similar Fund
Performance."

Expense Example

The  following  example  illustrates  the  expenses you would incur on a $10,000
investment in the UltraBull VP, and are intended to help you compare the cost of
investing  in the  UltraBull  VP compared  to other  mutual  funds.  The example
assumes that you invest for the time periods shown and redeem all of your shares
at the end of each period,  that the  UltraBull VP earns an annual  return of 5%
over the periods shown, that you reinvest all dividends and  distributions,  and
that gross  operating  expenses  remain  constant.  The example does not reflect
separate account or insurance contract fees and charges.  Because the example is
hypothetical and for comparison only, your actual costs will be different.

                                                                        Strategy

What the UltraBull VP Does

The UltraBull VP:

 .    Seeks  to   provide   investors   with   predictable   investment   returns
     approximating  the S&P 500  Index 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 UltraBull VP Does Not Do

ProFund Advisors does not:

 .    Conduct  conventional  stock  research or analysis or forecast stock market
     movement in managing the assets of the UltraBull VP.

 .    Invest the assets of the  UltraBull  VP in stocks or  instruments  based on
     ProFund   Advisors'  view  of  the  fundamental   prospects  of  particular
     companies.

 .    Adopt  defensive  positions by investing  in cash or other  instruments  in
     anticipation of an adverse climate for the UltraBull VP's benchmark index.

 .    Seek to invest to realize dividend income from investments.

In addition,  the UltraBull VP does not seek to provide correlation with the S&P
500 Index over a period of time other than daily,  such as monthly or  annually,
since  mathematical  compounding  prevents the UltraBull VP from  achieving such
results.

Important Concepts

 .    Leverage offers a means of magnifying small market  movements,  up or down,
     into large changes in an investment's value.

 .    Futures,  or futures  contracts,  are contracts to pay a fixed price for an
     agreed-upon  amount of commodities or securities,  or the cash value of the
     commodity or securities, on an agreed-upon date.

 .    Option  contracts  grant one party a right,  for a price,  either to buy or
     sell a security  or  futures  contract  at a fixed sum  during a  specified
     period or on a specified day.

Non-Diversification

The UltraBull VP is classified as "non-diversified" under the federal securities
laws.  It has the ability to  concentrate  a relatively  high  percentage of its
investments  in the  securities  of a small  number  of  companies,  if  ProFund
Advisors  determines  that doing so is the most efficient  means of tracking the
S&P 500  Index.  This  would  make  the  performance  of the  UltraBull  VP more
susceptible  to a single  economic,  political or  regulatory  event than a more
diversified  mutual fund might be.  Nevertheless,  the  UltraBull  VP intends to
invest on a diversified basis.

Portfolio Turnover

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

                                                             General Information

Calculating the UltraBull VP's Share Price


The  UltraBull  VP  calculates  daily share prices on the basis of the net asset
value of its  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 the UltraBull VP are traded in markets on days when the UltraBull
VP's principal trading market is closed,  the UltraBull VP's net asset value may
vary on days when investors cannot purchase or redeem shares.

The UltraBull VP values shares by dividing the market value of the assets,  less
the liabilities,  by the number of outstanding shares. The UltraBull VP uses the
following  methods for arriving at the current market price of investments  held
by it:

 .    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; and

 .    short-term debt securities are valued at amortized cost, which approximates
     market value.

When price  quotes are not readily  available,  securities  and other assets are
valued at fair value in good faith under  procedures  established  by, and under
the general  supervision  and  responsibility  of, the 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 UltraBull VP 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 the Christmas holiday.

Purchasing and Redeeming Shares

Shares of the  UltraBull VP are  available  for  purchase by  insurance  company
separate  accounts  to serve as an  investment  medium  for  variable  insurance
contracts,  and by qualified  pension and retirement  plans,  certain  insurance
companies,  and ProFund  Advisors.  Shares of the  UltraBull VP are purchased or
redeemed  at the net asset  value per share next  determined  after  receipt and
acceptance of a purchase order or redemption request.  The UltraBull VP reserves
the right to reject or refuse, in its discretion,  any order for the purchase of
its shares, in whole or in part.

Payment  for shares  redeemed  normally  will be made  within  seven  days.  The
UltraBull  VP intends to pay cash for all shares  redeemed,  but under  abnormal
conditions  which make  payment in cash  unwise,  payment  may be made wholly or
partly  in  portfolio  securities  at  their  then  market  value  equal  to the
redemption  price. A shareholder  may incur  brokerage  costs in converting such
securities  to cash.  Payment  for  shares may be  delayed  under  extraordinary
circumstances or as permitted by the Securities and Exchange Commission in order
to protect remaining investors.

Investors  do not deal  directly  with the  UltraBull  VP to  purchase or redeem
shares.  Please refer to the prospectus for the separate account for information
on the  allocation  of premiums  and on  transfers  of  accumulated  value among
sub-accounts of the separate accounts that invest in the UltraBull VP.

The UltraBull VP currently  does not foresee any  disadvantages  to investors if
the UltraBull VP served as investment media for both variable annuity  contracts
and variable life insurance policies. However, it is theoretically possible that
the interest of owners of annuity contracts and insurance policies for which the
UltraBull  VP served as an  investment  medium might at some time be in conflict
due to  differences  in tax  treatment  or other  considerations.  The  Board of
Trustees and each  participating  insurance company would be required to monitor
events to identify any material  conflicts  between  variable  annuity  contract
owners and variable life insurance  policy  owners,  and would have to determine
what action, if any, should be taken in the event of such a conflict.  If such a
conflict occurred,  an insurance company participating in the UltraBull VP might
be required to redeem the  investment  of one or more of its  separate  accounts
from the UltraBull VP, which might force the UltraBull VP to sell  securities at
disadvantageous prices.

The UltraBull VP reserves the right to discontinue  offering shares at any time.
In the event that the UltraBull VP ceases  offering its shares,  any investments
allocated to it may, subject to any necessary regulatory approvals,  be invested
in another fund managed by ProFund  Advisors deemed  appropriate by the Board of
Trustees.

Distribution of Shares

Under a distribution plan adopted by the Board of Trustees, the UltraBull VP may
pay financial  intermediaries  an annual fee of up to 0.25% of its average daily
net assets as  reimbursement  or  compensation  for  providing  or  procurring a
variety of services  relating to the promotion,  sale and servicing of shares of
the UltraBull VP. Over time,  fees paid under the plan will increase the cost of
your investment and may cost you more than other types of sales charges.

Tax Information

To comply with regulations  under the Internal Revenue Code, the UltraBull VP is
required to  diversify  its  investments.  Generally,  the  UltraBull VP will be
required to diversify its investments so that on the last day of each quarter of
a calendar year no more than 55% of the value of its total assets is represented
by any one investment,  no more than 70% is represented by any two  investments,
no more than 80% is represented by any three  investments,  and no more than 90%
is represented by any four investments.  For this purpose, securities of a given
issuer generally are treated as one investment,  but each U.S. Government agency
and  instrumentality  is treated  as a separate  issuer.  Any  security  issued,
guaranteed,  or insured (to the extent so  guaranteed or insured) by the U.S. or
an agency or  instrumentality of the U.S. is treated as a security issued by the
U.S. Government or its agency or instrumentality, whichever is applicable.

If the UltraBull VP fails to meet this diversification requirement,  income with
respect to variable insurance contracts invested in the UltraBull VP at any time
during the calendar quarter in which the failure occurred could become currently
taxable to the owners of the contracts. Similarly, income for prior periods with
respect to such contracts also could be taxable,  most likely in the year of the
failure to achieve the required diversification.  Other adverse tax consequences
also could ensue.

Because you do not own shares in the  UltraBull VP directly,  generally  you are
not taxed directly on distributions  from the UltraBull VP. However,  you may be
subject to taxation when you receive  distributions  from your variable  annuity
contract or variable life insurance  policy.  You should refer to the prospectus
for your  contract  or policy  for  information  on the taxes  relating  to your
investment and the tax  consequences of any withdrawal of your  investment.  You
may also  wish to  consult  with  your own tax  advisor  about  your  particular
situation,  and the tax  consequences of your  investment  under state and local
laws.

Reference  is made to the  prospectus  for the  separate  account  and  variable
insurance contract for information regarding the federal income tax treatment of
distributions  to  the  separate  account.   See  the  Statement  of  Additional
Information for more information on taxes.

                                                        Similar Fund Performance

The following table provides information  concerning the historical total return
performance of the Investor Class shares of the UltraBull  ProFund (the "Similar
Fund"),  another series of the Trust. The Similar Fund's investment  objectives,
policies and strategies are substantially  similar to those of the UltraBull VP,
and it is currently  managed by the same investment  team.  While the investment
objectives,  policies  and risks of the Similar  Fund and the  UltraBull  VP are
similar, the performance of the Similar Fund and the UltraBull VP will vary. The
data is provided  to  illustrate  the past  performance  of ProFund  Advisors in
managing a substantially similar investment portfolio and does not represent the
past performance of the UltraBull VP or the future  performance of the UltraBull
VP or its investment team. Consequently, potential investors should not consider
this  performance  data  as an  indication  of  the  future  performance  of the
UltraBull VP or of its investment team.

The  performance  data shown below  reflects the net  operating  expenses of the
Similar  Fund,  which are lower than the  estimated  operating  expenses  of the
UltraBull  VP.  Performance  would have been lower for the  Similar  Fund if the
expenses of the  UltraBull VP were used. In addition,  the Similar Fund,  unlike
the UltraBull  VP, is not sold to insurance  company  separate  accounts to fund
variable insurance  contracts.  As a result,  the performance  results presented
below do not take into account charges or deductions  against a separate account
or variable  insurance  contract for cost of insurance  charges,  premium loads,
administrative fees, maintenance fees, premium taxes, mortality and expense risk
charges,  or other  charges  that may be  incurred  under a  variable  insurance
contract for which the UltraBull VP serves as an underlying  investment vehicle.
By contrast, investors with contract value allocated to the UltraBull VP will be
subject to charges and expenses  relating to variable  insurance  contracts  and
separate accounts.

The Similar Fund's performance data shown below is calculated in accordance with
standards   prescribed  by  the  Securities  and  Exchange  Commission  for  the
calculation of average annual total return  information.  The investment results
of the  Similar  Fund  presented  below are  unaudited  and are not  intended to
predict or suggest  results that might be experienced by the Similar Fund or the
UltraBull  VP. Share prices and  investment  returns will  fluctuate  reflecting
market conditions. The performance data for the benchmark index identified below
does not reflect the fees or expenses of the Similar Fund or the UltraBull VP.

                       STATEMENT OF ADDITIONAL INFORMATION

                        7900 WISCONSIN AVENUE, SUITE 300

     This  Statement  of  Additional  Information  describes  one  series of the
ProFunds, the ProFund VP UltraBull (the "UltraBull VP"). The UltraBull VP 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 UltraBull VP seeks investment results that correspond
each day to a specified benchmark. The UltraBull VP may be used independently or
in  combination  with  other  ProFund  series as part of an  overall  investment
strategy. Additional series may be created from time-to-time.

     Shares of the UltraBull VP are available for purchase by insurance  company
separate  accounts  to serve as an  investment  medium  for  variable  insurance
contracts,  and by qualified  pension and retirement  plans,  certain  insurance
companies, and ProFund Advisors LLC (the "Advisor").

     The UltraBull VP involves special risks, some not traditionally  associated
with mutual funds. Investors should carefully review and evaluate these risks in
considering an investment in the UltraBull VP to determine whether an investment
in the UltraBull VP is appropriate. Investing in the UltraBull VP alone does not
constitute  a balanced  investment  plan.  The  UltraBull VP 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 objective of the UltraBull VP will be achieved.

     This Statement of Additional Information is not a prospectus.  It should be
read in conjunction with the Prospectus,  dated March [ ], 2001, as supplemented
from time-to-time,  which incorporates this Statement of Additional  Information
by reference.  Words or phrases used in the Statement of Additional  Information
without  definition have the same meaning as ascribed to them in the Prospectus.
A copy of the  Prospectus  is  available,  without  charge,  upon request to the
address above or by telephoning at the telephone numbers above.

    The date of this Statement of Additional Information is March [ ], 2001.

                                    PROFUNDS

     ProFunds (the "Trust") is an open-end management  investment  company,  and
currently  comprises [ ] separate series. One of these series, the UltraBull VP,
is discussed  herein.  The UltraBull VP is one among several series of the Trust
which is offered to insurance  company separate  accounts and qualified  pension
and  retirement  plans.  The  UltraBull  VP is  classified  as  non-diversified,
although it currently intends to operate in a diversified manner.  Other similar
series may be added in the future.

                       INVESTMENT POLICIES AND TECHNIQUES

GENERAL

     The investment objective of the UltraBull VP is to provide daily investment
results that correspond to twice (200%) the performance of the S&P 500 Composite
Stock Price Index(R)  ("S&P 500 Index").  The UltraBull VP seeks to achieve this
correlation on each trading day. Under its investment  objective,  the UltraBull
VP should  produce  greater gains to investors  when the S&P 500 Index rises and
greater  losses when the S&P 500 Index declines over the  corresponding  gain or
loss of a  conventional  S&P 500  Index  ProFund  VP.  Reference  is made to the
Prospectus  for a discussion  of the  investment  objective  and policies of the
UltraBull VP. In addition,  set forth below is further  information  relating to
the  UltraBull  VP.  The  discussion  below  supplements  and  should be read in
conjunction with the Prospectus.

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

     Certain investment restrictions of the UltraBull VP specifically identified
as fundamental  policies may not be changed without the  affirmative  vote of at
least the majority of the outstanding  shares of the UltraBull VP, as defined in
the  Investment  Company Act of 1940,  as amended  (the "1940  Act").  All other
investment policies of the UltraBull VP not specified as fundamental  (including
the  investment  objective  and benchmark of the UltraBull VP) may be changed by
the trustees of the UltraBull VP without the approval of shareholders.

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

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

     It is the policy of the UltraBull VP to pursue its investment objectives of
correlating with its benchmark regardless of market conditions, to remain nearly
fully invested and not to take defensive positions.

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

FUTURES CONTRACTS AND RELATED OPTIONS

     The  UltraBull VP 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 the UltraBull VP purchases a put or call option on a futures contract,
the UltraBull VP 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,
the  UltraBull VP receives a premium in return for granting to the  purchaser of
the  option  the right to sell to or buy from the  UltraBull  VP the  underlying
futures  contract  for a  specified  price upon  exercise at any time during the
option period.

     Whether the  UltraBull VP realizes a gain or loss from  futures  activities
depends generally upon movements in the underlying commodity.  The extent of the
UltraBull VP's loss from an unhedged short position in futures contracts or from
writing options on futures contracts is potentially unlimited.  The UltraBull VP
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 the UltraBull VP, or selling an option of the same series
as an option  previously  purchased by the  UltraBull  VP. The UltraBull VP will
engage in transactions in futures  contracts and related options that are traded
on a U.S.  exchange or board of trade or that have been approved for sale in the
U.S. by the Commodity Futures Trading Commission.

     When the UltraBull VP purchases or sells a stock index futures contract, or
sells an option  thereon,  the UltraBull VP "covers" its position.  To cover its
position,  the  UltraBull VP 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  UltraBull  VP 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 the  UltraBull  VP would be excluded  from the  definition  of a
"commodity  pool  operator."  Under  Section  4.5 of the CFTC  Regulations,  the
UltraBull VP 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 UltraBull VP'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.
<PAGE>

     The UltraBull VP will cover its position when it writes a futures  contract
or option on a futures contract.  The UltraBull VP 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 UltraBull VP will maintain,  in a segregated
account, cash or liquid instruments equal in value to the difference between the
strike price of the put and the price of the future.  The  UltraBull VP 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.  The UltraBull VP 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.

     The UltraBull VP 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  UltraBull VP will  maintain in a
segregated  account liquid  instruments equal in value to the difference between
the strike price of the call and the price of the future.  The  UltraBull VP 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.  The  UltraBull  VP 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  UltraBull VP 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.
The UltraBull VP 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 UltraBull VP intends 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  the UltraBull VP to substantial
losses.  If trading is not possible,  or if the  UltraBull VP determines  not to
close a futures  position  in  anticipation  of  adverse  price  movements,  the
UltraBull VP will be required to make daily cash  payments of variation  margin.
The risk that the  UltraBull  VP will be unable to close out a futures  position
will be minimized by entering into such transactions on a national exchange with
an active and liquid secondary market.

INDEX OPTIONS

     The  UltraBull VP may purchase and write options on stock indexes to create
investment exposure consistent its investment objectives,  to hedge or limit the
exposure of its 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.
<PAGE>

     Index  options  are subject to  substantial  risks,  including  the risk of
imperfect  correlation  between the option price and the value of the underlying
securities  composing the stock index selected and the risk that there might not
be a liquid  secondary  market  for the  option.  Because  the value of an index
option depends upon movements in the level of the index rather than the price of
a particular  stock,  whether the  UltraBull VP 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 the UltraBull VP 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. The UltraBull VP will not
enter into an option  position that exposes the UltraBull VP to an obligation to
another party, unless the UltraBull VP either (i) owns an offsetting position in
securities or other options and/or (ii) maintains with its 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 UltraBull VP 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  its  investment  objectives.
Options on indexes are  settled in cash,  not by  delivery  of  securities.  The
exercising holder of an index option receives, instead of a security, cash equal
to the  difference  between the closing  price of the  securities  index and the
exercise price of the option.

     Some stock index  options are based on a broad market index such as the S&P
500 Index,  the NYSE Composite  Index,  or the AMEX Major Market Index,  or on a
narrower index such as the Philadelphia Stock Exchange  Over-the-Counter  Index.
Options currently are traded on the Chicago Board Options Exchange (the "CBOE"),
the AMEX, and other exchanges ("Exchanges").  Purchased over-the-counter options
and the cover for written  over-the-counter  options  will be subject to the 15%
limitation  on  investment  in  illiquid  securities  by the  UltraBull  VP. 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 the  UltraBull VP may buy or
sell; however, the Advisor intends to comply with all limitations.
<PAGE>

OPTIONS ON SECURITIES

     The  UltraBull VP may buy and write (sell)  options on  securities  for the
purpose of realizing its  investment  objectives.  By buying a call option,  the
UltraBull VP 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,  the UltraBull VP 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, the UltraBull
VP 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,  the UltraBull VP 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,  the  UltraBull VP may cover its  position by owning the  underlying
security on which the option is written.  Alternatively,  the  UltraBull  VP 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 UltraBull VP
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,  the  UltraBull VP 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 UltraBull  VP. When the  UltraBull VP writes a put option,  the UltraBull VP
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 the  UltraBull  VP to write call options on stocks held by
the  UltraBull VP is to attempt to realize,  through the receipt of premiums,  a
greater return than would be realized on the underlying securities alone.

     If the  UltraBull VP writes an option and wishes to terminate the UltraBull
VP's obligation,  the UltraBull VP may effect a "closing purchase  transaction."
The UltraBull VP accomplishes this by buying an option of the same series as the
option  previously  written by the  UltraBull  VP. 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, the UltraBull VP which is the holder of an
option may liquidate its position by effecting a "closing sale transaction." The
UltraBull  VP  accomplishes  this by selling an option of the same series as the
option  previously  purchased by the  UltraBull  VP. 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.  The  UltraBull  VP 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 UltraBull VP if the premium,  plus commission  costs, paid by the
UltraBull VP to purchase the call or put option to close the transaction is less
(or greater) than the premium,  less commission costs, received by the UltraBull
VP on the sale of the call or the put option. The UltraBull VP also will realize
a gain if a call  or put  option  which  the  UltraBull  VP has  written  lapses
unexercised, because the UltraBull VP 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 the  UltraBull  VP. If an  options  market  were to become
unavailable,  the  UltraBull  VP would be unable to realize its profits or limit
its losses  until the  UltraBull  VP could  exercise  options it holds,  and the
UltraBull VP 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  UltraBull  VP 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  UltraBull  VP  calculate  the
obligations of the parties to the agreement on a "net basis." Consequently,  the
UltraBull  VP'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").

     The  UltraBull  VP's current  obligations  under a swap  agreement  will be
accrued  daily  (offset  against any amounts  owing to the UltraBull VP) 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 the
UltraBull VP'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 UltraBull VP
illiquid investment  limitations.  The UltraBull VP will not enter into any swap
agreement unless the Advisor believes that the other party to the transaction is
creditworthy.  The UltraBull VP bears the risk of loss of the amount expected to
be received  under a swap agreement in the event of the default or bankruptcy of
a swap agreement counterparty.
<PAGE>

     The  UltraBull  VP 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 UltraBull VP 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 UltraBull VP 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 UltraBull VP 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 UltraBull VP on the notional amount.

     Swap agreements  typically are settled on a net basis, which means that the
two payment  streams are netted out,  with the UltraBull VP 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 the UltraBull VP is contractually obligated to make.
If the other party to a swap agreement defaults, the UltraBull VP's risk of loss
consists of the net amount of payments  that the  UltraBull VP is  contractually
entitled  to  receive,  if any.  The net amount of the  excess,  if any,  of the
UltraBull VP'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 the UltraBull VP'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 UltraBull
VP and its Advisor believe that transactions do not constitute senior securities
under the 1940 Act and, accordingly, will not treat them as being subject to the
UltraBull VP'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,  is responsible  for  determining and
monitoring the liquidity of the UltraBull VP's 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.
<PAGE>

AMERICAN DEPOSITORY RECEIPTS

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

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

     The  UltraBull  VP 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

     The UltraBull VP also may invest in U.S.  government  securities in pursuit
of its  investment  objectives,  as "cover" for the  investment  techniques  the
UltraBull VP employs, 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 the UltraBull VP's portfolio investments in U.S. government securities, while
a decline in interest  rates would  generally  increase  the market value of the
UltraBull VP'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

     The  UltraBull  VP may enter  into  repurchase  agreements  with  financial
institutions.  Under a repurchase  agreement,  the UltraBull VP 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 UltraBull VP follows 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,  the UltraBull VP 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 UltraBull VP could suffer a
loss. The UltraBull VP also may experience  difficulties and incur certain costs
in  exercising  its  rights  to the  collateral  and may lose the  interest  the
UltraBull  VP 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 UltraBull VP 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 UltraBull VP,  amounts to more than 15%
of its total net assets.  The  investments  of the  UltraBull  VP 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,  the  UltraBull  VP may  temporarily
invest all or part of the  UltraBull  VP'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  UltraBull VP may use reverse  repurchase  agreements  as part of their
investment  strategies.  Reverse  repurchase  agreements  involve  sales  by the
UltraBull VP of portfolio assets concurrently with an agreement by the UltraBull
VP to  repurchase  the same assets at a later date at a fixed price.  Generally,
the effect of such a  transaction  is that the  UltraBull  VP can recover all or
most of the cash invested in the portfolio  securities  involved during the term
of the reverse repurchase agreement, while the UltraBull VP will be able to keep
the  interest  income   associated  with  those   portfolio   securities.   Such
transactions are  advantageous  only if the interest cost to the UltraBull VP 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 UltraBull VP intends to use the reverse  repurchase  technique only when
it will be to the  UltraBull  VP's  advantage  to do so. The  UltraBull  VP will
establish a segregated account with its custodian bank in which the UltraBull VP
will maintain cash or liquid  instruments  equal in value to the UltraBull  VP's
obligations in respect of reverse repurchase agreements.

BORROWING

     The  UltraBull  VP  may  borrow  money  for  cash  management  purposes  or
investment  purposes.  The  UltraBull VP may also enter into reverse  repurchase
agreements,  which  may  be  viewed  as a  form  of  borrowing,  with  financial
institutions.  However,  to the extent the UltraBull VP "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 UltraBull VP. 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 the UltraBull VP's assets
will fluctuate in value,  whereas the interest  obligations on borrowings may be
fixed, the net asset value per share of the UltraBull VP will increase more when
the UltraBull VP's portfolio assets increase in value and decrease more when the
UltraBull VP'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,  the UltraBull VP 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,  the  UltraBull  VP 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  UltraBull  VP's assets  should fail to meet this 300%
coverage test,  the UltraBull VP, within three days (not  including  Sundays and
holidays), will reduce the amount of the UltraBull VP'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 UltraBull VP is 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  UltraBull  VP's  total  assets.  This
borrowing is not subject to the foregoing 300% asset coverage  requirement.  The
UltraBull VP is authorized to pledge  portfolio  securities as the Advisor deems
appropriate in connection with any borrowings.

LENDING OF PORTFOLIO SECURITIES

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

WHEN-ISSUED AND DELAYED-DELIVERY SECURITIES

     The UltraBull  VP, 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 the UltraBull
VP  makes  the   commitment  to  purchase   securities   on  a  when-issued   or
delayed-delivery  basis,  the  UltraBull  VP will  record  the  transaction  and
thereafter  reflect the value of the  securities,  each day, in determining  the
UltraBull VP's net asset value. The UltraBull VP will not purchase securities on
a when-issued or  delayed-delivery  basis if, as a result,  more than 15% of the
UltraBull  VP'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 UltraBull VP will maintain liquid  instruments equal
to or greater in value than the  UltraBull  VP's purchase  commitments  for such
when-issued or delayed-delivery  securities,  or the Trust does not believe that
the UltraBull  VP's net asset value or income will be adversely  affected by the
UltraBull  VP's  purchase of securities  on a  when-issued  or delayed  delivery
basis.

INVESTMENTS IN OTHER INVESTMENT COMPANIES

     The UltraBull VP 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 the UltraBull VP invests in, and, thus, is a shareholder of,
another investment company, the UltraBull VP's shareholders will indirectly bear
the  UltraBull  VP'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 UltraBull VP to the UltraBull VP's own
investment  adviser and the other  expenses that the UltraBull VP bears directly
in connection with the UltraBull VP's own operations.

ILLIQUID SECURITIES

     While the UltraBull VP anticipates  doing so, the UltraBull VP 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. The UltraBull VP
will not  invest  more than 15% of the  UltraBull  VP'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 UltraBull VP 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  UltraBull  VP 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,  the
UltraBull  VP 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  the  UltraBull  VP  have   delegated  this
responsibility for determining the liquidity of Rule 144A restricted  securities
which may be invested in by the UltraBull VP 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 UltraBull VP's liquidity.

PORTFOLIO TURNOVER

     The nature of the  UltraBull VP will cause the  UltraBull VP 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 UltraBull  VP. In addition,  the UltraBull
VP's portfolio  turnover level may adversely affect the ability of the UltraBull
VP to achieve its  investment  objective.  Because the UltraBull  VP's portfolio
turnover  rate to a great extent will depend on the  purchase,  redemption,  and
exchange  activity of the UltraBull VP's investors,  it is difficult to estimate
what the UltraBull VP'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  UltraBull  VP invests  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 the
UltraBull VP is calculated without regard to instruments,  including options and
futures contracts, having a maturity of less than one year.

SPECIAL CONSIDERATIONS

     To the extent  discussed  above and in the  prospectus,  the  UltraBull  VP
presents certain risks, some of which are further described below.

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

     LEVERAGE.  The UltraBull VP intends to regularly  use leveraged  investment
techniques  in pursuing its  investment  objectives.  Utilization  of leveraging
involves  special  risks and should be considered  to be  speculative.  Leverage
exists when the  UltraBull  VP achieves  the right to a return on a capital base
that exceeds the amount the  UltraBull  VP has  invested.  Leverage  creates the
potential for greater gains to shareholders of the UltraBull VP 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
the UltraBull VP'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 UltraBull VP to pay interest  which would  decrease the UltraBull VP's total
return to shareholders.  If the UltraBull VP achieves its investment objectives,
during  adverse  market  conditions,  shareholders  should  experience a loss of
approximately twice the amount they would have incurred had the UltraBull VP not
been leveraged.
<PAGE>

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

                             INVESTMENT RESTRICTIONS

     The UltraBull VP has adopted certain investment restrictions as fundamental
policies  which  cannot be changed  without  the  approval  of the  holders of a
"majority"  of the  outstanding  shares  of the  UltraBull  VP,  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
UltraBull VP are present or represented  by proxy;  or (ii) more than 50% of the
outstanding  shares  of  the  series.  (All  policies  of the  UltraBull  VP 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 UltraBull  VP.) For purposes of the following  limitations,  all  percentage
limitations apply immediately after a purchase or initial investment.

     The UltraBull VP 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  UltraBull  VP 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.
<PAGE>

     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  UltraBull  VP 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  UltraBull  VP (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 UltraBull VP may not pledge its assets
              other than to secure such  borrowings or, to the extent  permitted
              by the  UltraBull  VP's  investment  policies  as set forth in the
              Prospectus and this Statement of Additional  Information,  as they
              may be  amended  from time to time,  in  connection  with  hedging
              transactions,  short  sales,  when-issued  and forward  commitment
              transactions and similar investment strategies.

     7.       Underwrite  securities  of other  issuers,  except  insofar as the
              UltraBull VP 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  UltraBull  VP may  do so in  accordance  with
              applicable law and the UltraBull VP'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 UltraBull VP 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 the UltraBull VP are traded in
other markets on days when the UltraBull  VP's  principal  trading  market(s) is
closed,  the  UltraBull  VP's net  asset  value  may be  affected  on days  when
investors do not have access to the  UltraBull VP to purchase or redeem  shares.
Although the  UltraBull  VP expect the same holiday  schedules to be observed in
the future, the exchanges may modify their holiday schedules at any time.

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

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

     The futures  contracts  maintained  by the UltraBull VP 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 the UltraBull
VP 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 the UltraBull VP 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 the UltraBull VP, the
selection of brokers and dealers to effect the transactions, and the negotiation
of brokerage commissions,  if any. The Advisor expects that the UltraBull VP 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 to the UltraBull VP 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
to the UltraBull VP 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  portfolio of the  UltraBull VP and the
other client accounts.

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

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

     In seeking to implement the UltraBull  VP'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 UltraBull VP 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 the UltraBull VP
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.

                             MANAGEMENT OF PROFUNDS

     The Board of Trustees is  responsible  for the general  supervision  of the
Trust's   business.   The   day-to-day   operations  of  the  ProFunds  are  the
responsibilities  of ProFunds'  officers.  The names and addresses (and ages) of

PROFUND ADVISORS LLC

     Under an  investment  advisory  agreement  between the UltraBull VP and the
Advisor,  dated  [__________],  the  UltraBull  VP 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 the UltraBull VP,
in accordance with the investment  objectives,  policies, and limitations of the
UltraBull VP, subject to the general supervision and control of the Trustees and
the officers of the UltraBull VP. 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 UltraBull VP,  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 UltraBull VP 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")
acts as  Administrator  to the  UltraBull  VP. The  Administrator  provides  the
UltraBull  VP with all  required  general  administrative  services,  including,
without limitation, office space, equipment, and personnel; clerical and general
back  office  services;   bookkeeping,   internal  accounting,  and  secretarial
services;  the determination of net asset values; and the preparation and filing
of all  reports,  registration  statements,  proxy  statements,  and  all  other
materials  required to be filed or furnished by the  UltraBull VP under  Federal
and state  securities  laws. The  Administrator  also maintains the  shareholder
account records for the UltraBull VP,  distributes  dividends and  distributions

the  ProFund  family of funds up to $300  million,  the fee is 0.15% of  average
daily net assets,  and it  declines to 0.05% for average  daily net assets of $1
billion or more on an anuual basis.  BISYS Funds  Services,  Inc.  ("BFSI"),  an
affiliate of BISYS,  acts as transfer  agent and fund  accounting  agent for the
UltraBull VP, for which it receives additional fees. Additionally, the UltraBull
VP 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

ADMINISTRATIVE SERVICES

     The  Trust,   on  behalf  of  the   UltraBull   VP,  has  entered  into  an
administrative   services   agreement  with  American   Skandia  Life  Assurance
Corporation ("American Skandia") pursuant to which American Skandia will provide
administrative  services with respect to the  UltraBull  VP. These  services may
include,  but are not limited to: coordinating matters relating to the operation
of  American  Skandia's  separate  account  with  the  UltraBull  VP,  including
necessary   coordination   with  other  service   providers;   coordinating  the
preparation  of necessary  documents to be submitted to regulatory  authorities;
providing  assistance to variable  contract  owners who use or intend to use the
UltraBull VP as a funding  vehicle for their  variable  contracts;  coordinating
with the Advisor  regarding  investment  limitations and parameters to which the
UltraBull VP is subject; and generally assisting with compliance with applicable
regulatory  requirements.  For these services, the Trust pays American Skandia a
quarterly fee equal on an annual basis to [.35%] of the average daily net assets
of the  UltraBull  VP that are  invested in the  UltraBull  VP through  American
Skandia's separate account.

     From  time to time the  UltraBull  VP and/or  the  Advisor  may enter  into
arrangements  under which  certain  administrative  services may be performed by
other  insurance  companies  that  purchase  shares of the  UltraBull  VP. These
administrative  services may include, among other things, the services set forth
above, as well as responding to ministerial  inquiries  concerning the UltraBull
VP  investment  objectives,   investment  programs,  policies  and  performance,
transmitting,  on behalf of the UltraBull VP, proxy statements,  annual reports,
updated prospectuses,  and other communications  regarding the UltraBull VP, and
providing  any  related  services  as  the  UltraBull  VP or its  investors  may
reasonably request.  Depending on the arrangements,  the UltraBull VP and/or the
Advisor may  compensate  such  insurance  companies or their agents  directly or
indirectly  for the  administrative  services.  To the extent the  UltraBull  VP
compensates the insurance company for these services,  the UltraBull VP will pay
the insurance  company an annual fee that may vary  depending upon the number of
investors  that  utilize  the  UltraBull  VP as the  funding  medium  for  their
contracts.  The insurance  company may impose other account or service  charges.
See the  prospectus  for the  separate  account  of the  insurance  company  for
additional information regarding such charges.

INDEPENDENT ACCOUNTANTS

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

LEGAL COUNSEL

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

DISTRIBUTION PLAN

     Pursuant  to a  Distribution  Plan,  the  UltraBull  VP  may  reimburse  or
compensate financial  intermediaries from their assets for services rendered and
expenses borne in connection with activities primarily intended to result in the
sale of the  UltraBull  VP's  shares.  It is  anticipated  that a portion of the
amounts paid by the UltraBull VP will be used to defray  various costs  incurred
in  connection  with the  printing  and mailing of a  prospectus,  statement  of
additional information and any supplements thereto, and shareholder reports, and
holding  seminars and sales meetings with  wholesale and retail sales  personnel
designed to promote the distribution of the Fund's shares. The UltraBull VP also
may   reimburse  or  compensate   financial   intermediaries   and   third-party
broker-dealers  for their services in connection  with the  distribution  of the
shares of the UltraBull VP.
<PAGE>

     The  Distribution  Plan provides that the Trust, on behalf of the UltraBull
VP,  will pay  annually  up to 0.25% of the  average  daily  net  assets  of the
UltraBull VP in respect of activities  primarily  intended to result in the sale
of its shares.  Under the terms of the Distribution Plan and related agreements,
the UltraBull VP is authorized  to make  quarterly  payments that may be used to
reimburse  or  compensate   entities  providing   distribution  and  shareholder
servicing with respect to the shares of the UltraBull VP for such entities' fees
or expenses incurred or paid in that regard.

     The Distribution  Plan is of a type known as a "compensation"  plan because
payments may be made for services rendered to the UltraBull VP regardless of the
level of  expenditures  by the  financial  intermediaries.  The  Trustees  will,
however,   take  into  account  such  expenditures  for  purposes  of  reviewing
operations  under  the  Distribution   Plan  in  connection  with  their  annual
consideration  of  the  Distribution  Plan's  renewal.  Expenditures  under  the
Distribution Plan may include, without limitation:  (a) the printing and mailing
of a UltraBull  VP  prospectus,  statement  of  additional  information  and any
supplements  thereto,  and shareholder  reports for prospective  investors;  (b)
those  relating  to  the  development,  preparation,  printing  and  mailing  of
advertisements,  sales  literature and other  promotional  materials  describing
and/or  relating to the  UltraBull VP; (c) holding  seminars and sales  meetings
designed to promote the distribution of the UltraBull VP's shares; (d) obtaining
information and providing  explanations to wholesale and retail  distributors of
contracts regarding the investment objectives and policies and other information
about the  UltraBull  VP,  including  the  performance  of the UltraBull VP; (e)
training sales personnel regarding the UltraBull VP; and (f) financing any other
activity  that is  primarily  intended  to  result  in the sale of shares of the
UltraBull VP. In addition, a financial  intermediary may enter into an agreement
with the Trust under which it would be  entitled  to receive  compensation  for,
among other things,  making the UltraBull VP available to its contract owners as
a funding vehicle for variable insurance contracts.

     The Distribution Plan and any related agreement that is entered into by the
Trust in  connection  with the  Distribution  Plan will continue in effect for a
period  of more  than  one  year  only so long as  continuance  is  specifically
approved  at least  annually  by a vote of a majority  of the  Trust's  Board of
Trustees,  and of a majority of the Trustees who are not "interested persons" of
the  Trust  and  who  have  no  financial  interest  in  the  operation  of  the
Distribution  Plan  (the  "Independent  Trustees"),  cast in person at a meeting
called  for the  purpose  of  voting  on the  Distribution  Plan or any  related
agreement,  as applicable.  In addition,  the Distribution  Plan and any related
agreement may be terminated as to a UltraBull VP at any time,  without  penalty,
by vote of a majority of the  outstanding  shares of the UltraBull VP or by vote
of a majority of the Independent  Trustees.  The Distribution Plan also provides
that it may not be amended  to  increase  materially  the amount (up to 0.25% of
average daily net assets  annually) that may be spent for distribution of shares
of the UltraBull VP without the approval of shareholders of the UltraBull VP.

                               COSTS AND EXPENSES

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

          ORGANIZATION AND DESCRIPTION OF SHARES OF BENEFICIAL INTEREST

     ProFunds is a registered  open-end  investment  company under the 1940 Act.
The Trust was organized as a Delaware  business trust on April 17, 1997, and has
authorized  capital of unlimited  shares of beneficial  interest of no par value
which  may be issued in more  than one  class or  series.  Currently,  the Trust
consists of [ ] separately  managed  series,  one of which is described  herein.
Other separate series may be added in the future.

     All shares of the UltraBull VP 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 UltraBull VP and the purchase,  ownership, and disposition of its
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 UltraBull VP shares,
as well as the tax  consequences  arising  under the laws of any state,  foreign
country, or other taxing jurisdiction.

     The  UltraBull VP 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, the UltraBull VP 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  UltraBull  VP'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  UltraBull  VP's
total assets and 10% of the outstanding  voting  securities of such issuer,  and
(ii) not more  than 25% of the  value of its total  assets  is  invested  in the
securities  of any one issuer  (other than U.S.  government  securities  and the
securities of other regulated investment companies).
<PAGE>

     As a RIC, the  UltraBull VP 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 UltraBull VP'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.  The UltraBull VP 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  UltraBull  VP level.  To avoid the tax, the  UltraBull  VP 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  UltraBull  VP  intends  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 UltraBull VP in October,  November or December of that year with
a record date in such a month and paid by the UltraBull VP during January of the
following  year.  Such  distributions  will be  taxable to  shareholders  in the
calendar year in which the distributions are declared,  rather than the calendar
year in which the distributions are received.

MARKET DISCOUNT

     If the  UltraBull  VP  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 UltraBull
VP in each taxable year in which the  UltraBull VP owns an interest in such debt
security and receives a principal payment on it. In particular, the UltraBull VP
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 the  UltraBull  VP at a
constant rate over the time remaining to the debt security's maturity or, at the
election of the UltraBull VP, 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 UltraBull VP 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 the UltraBull VP,  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  UltraBull VP at a discount
that exceeds the original issue discount on such debt  securities,  if any. This
additional  discount  represents market discount for federal income tax purposes
(see above).
<PAGE>

OPTIONS, FUTURES AND FOREIGN CURRENCY FORWARD CONTRACTS

     Any regulated  futures  contracts and certain  options  (namely,  nonequity
options and dealer  equity  options) in which the UltraBull VP 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 the
UltraBull  VP 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
UltraBull VP may result in  "straddles"  for federal  income tax  purposes.  The
straddle  rules may affect the  character  of gains (or losses)  realized by the
UltraBull VP, and losses realized by the UltraBull VP 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 the UltraBull
VP 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 UltraBull VP are not
entirely clear. The straddle rules may increase the amount of short-term capital
gain  realized  by the  UltraBull  VP,  which is taxed as  ordinary  income when
distributed to  shareholders.  Because  application  of the straddles  rules may
affect the  character of gains or losses,  defer losses  and/or  accelerate  the
recognition of gains or losses from the affected straddle positions,  the amount
which must be  distributed  to  shareholders  as  ordinary  income or  long-term
capital gain may be increased or decreased  substantially  as compared to a fund
that did not engage in such transactions.

CONSTRUCTIVE SALES

     Recently  enacted  rules may affect the timing and character of gain if the
UltraBull VP engages in  transactions  that reduce or eliminate its risk of loss
with respect to appreciated financial positions. If the UltraBull VP enters into
certain transactions in property while holding substantially identical property,
the UltraBull VP 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
UltraBull  VP'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 UltraBull VP's holding period and the application
of various loss deferral provisions of the Code.

PASSIVE FOREIGN INVESTMENT COMPANIES

     The UltraBull VP 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 the  UltraBull VP receives a so-called  "excess
distribution" with respect to PFIC stock, the UltraBull VP itself may be subject
to a  tax  on  a  portion  of  the  excess  distribution,  whether  or  not  the
corresponding  income is  distributed  by the UltraBull VP to  shareholders.  In
general,  under the PFIC rules, an excess distribution is treated as having been
realized  ratably over the period  during  which the  UltraBull VP held the PFIC
shares.  The UltraBull VP will itself be subject to tax on the portion,  if any,
of an excess  distribution  that is so allocated  to prior  UltraBull VP 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 UltraBull VP may be eligible to elect  alternative  tax treatment  with
respect to PFIC shares.  Under an election  that  currently is available in some
circumstances,  the  UltraBull VP 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  UltraBull  VP'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  UltraBull  VP  shares  would be
deductible  as  ordinary  losses to the extent of any net  mark-to-market  gains
included in income in prior years.
<PAGE>

BACKUP WITHHOLDING

     The UltraBull VP 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  UltraBull  VP with the  shareholder's  correct  taxpayer
identification  number or  social  security  number,  (2) the IRS  notifies  the
shareholder  or the  UltraBull  VP 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

     The UltraBull VP 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, the UltraBull VP 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  UltraBull   VP'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  UltraBull  VP is
required to distribute as dividends to  shareholders  in order for the UltraBull
VP 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
UltraBull VP's shares;  the total return on a shareholder's  investment will not
be reduced as a result of the UltraBull VP'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,  the UltraBull VP may advertise the total return of the
UltraBull VP 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  UltraBull VP. Other total return  quotations,  aggregate or
average, over other time periods for the UltraBull VP also may be included.

     The total return of the UltraBull VP for a particular period represents the
increase  (or  decrease)  in  the  value  of a  hypothetical  investment  in the
UltraBull  VP 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  UltraBull VP 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
UltraBull VP.

     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 the  UltraBull  VP,  comparisons  of the
performance  information  of  the  UltraBull  VP  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,  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
Deutche  Aktienindex,  all  of  which  are  unmanaged  market  indicators.  Such
comparisons  can be a  useful  measure  of the  quality  of the  UltraBull  VP's
investment performance. In particular, performance information for the UltraBull
VP may be compared to various unmanaged indexes,  including, but not limited to,
the S&P 500 Index or the Dow Jones Industrial Average.

     In addition,  rankings,  ratings, and comparisons of investment performance
and/or   assessments  of  the  quality  of  shareholder   service  appearing  in
publications such as Money,  Forbes,  Kiplinger's  Magazine,  Personal Investor,
Morningstar,  Inc., and similar sources which utilize  information  compiled (i)
internally,  (ii) by Lipper Analytical Services,  Inc.  ("Lipper"),  or (iii) by
other recognized analytical services, may be used in sales literature. The total
return of the  UltraBull  VP also may be compared to the  performances  of broad
groups of  comparable  mutual  funds  with  similar  investment  goals,  as such
performance is tracked and published by such independent organizations as Lipper
and CDA  Investment  Technologies,  Inc.,  among others.  The Lipper ranking and
comparison,  which may be used by the UltraBull VP in performance reports,  will
be drawn from the  "Capital  Appreciation  Funds"  grouping.  In  addition,  the
broad-based  Lipper  groupings  may  be  used.  Further  information  about  the
performance  of the UltraBull VP will be contained in the UltraBull  VP's annual
reports to shareholders,  which may be obtained without charge by writing to the
UltraBull VP at the address or  telephoning  the  UltraBull VP at the  telephone
number set forth on the cover page of this SAI.  However,  because the UltraBull
VP has 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

                        DESCRIPTION OF SECURITIES RATINGS

DESCRIPTION OF S&P'S CORPORATE RATINGS:

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

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

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

DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS:

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

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

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

DESCRIPTION OF FITCH INVESTORS SERVICE'S CORPORATE BOND RATINGS:

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

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

DESCRIPTION OF DUFF & PHELPS' CORPORATE BOND RATINGS:

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

     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.
<PAGE>

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.

DESCRIPTION OF FITCH INVESTORS SERVICE'S COMMERCIAL PAPER RATINGS:

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

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

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

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

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

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

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

     C-Obligations which are currently in default.

     Notes: "+" or "-".

DESCRIPTION OF MOODY'S COMMERCIAL PAPER RATINGS:

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

DESCRIPTION OF FITCH INVESTORS SERVICE'S COMMERCIAL PAPER RATINGS:

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

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

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

     C-Obligations  for which there is an  inadequate  capacity to ensure timely
repayment.

     D-Obligations  which have a high risk of default or which are  currently in
default.
<PAGE>

DESCRIPTION OF THOMSON BANK WATCH SHORT-TERM RATINGS:

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

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

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

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

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.
