PaineWebber   S&P 500 Index Fund

                        PAINEWEBBER S&P 500 INDEX FUND

                  INVESTMENT OBJECTIVE, STRATEGIES AND RISKS
                  ------------------------------------------




FUND OBJECTIVE

To replicate the total return of the S&P 500 Index, before fees and expenses.

PRINCIPAL INVESTMENT STRATEGIES

The fund invests primarily in common stocks issued by companies in the Standard
& Poor's 500 Composite Stock Price Index. The fund ordinarily invests in at
least 450 stocks that are represented in the Index in proportion to their
weighting in the Index. The fund also invests, to a lesser extent, in related
derivatives, such as options and futures contracts, that simulate investment in
the Index.

The S&P 500 Index is composed of 500 common stocks that are selected by Standard
& Poor's, a division of The McGraw-Hill Companies, Inc. ("S&P"). Most of these
500 stocks trade on the New York Stock Exchange. These stocks represent
approximately 75% of the market value of all U.S common stocks but do not
necessarily represent the largest companies. S&P selects the component stocks
included in the Index with the aim of achieving a distribution that is
representative of the various industry components of the U.S. market for common
stocks. S&P also considers aggregate market value and trading activity in the
selection process. Each stock in the Index is weighted by its total market value
relative to the total market value of all securities in the Index.

The fund's investment adviser, Mitchell Hutchins Asset Management Inc., uses a
"passive" investment approach in attending to replicate the investment
performance of the S&P 500 Index rather than actively buying and selling.
Mitchell Hutchins, however, may use options and futures and other derivatives in
strategies intended to simulate full investment in the S&P 500 Index stocks
while retaining a cash balance for fund management purposes. Mitchell Hutchins
also may use these instruments to reduce the risk of adverse price movements
while investing cash received when investors buy fund shares, to facilitate
trading and to reduce transaction costs.

The fund is not sponsored, endorsed, sold or promoted by S&P. S&P's only
relationship to the fund is the licensing of trademarks and trade names of S&P
and the S&P 500 Index, which is composed by S&P without regard to the fund. The
inclusion of a security in the S&P 500 Index in no way implies an opinion by S&P
as to the attractiveness of the security as an investment.

PRINCIPAL RISKS

An investment in the fund is not guaranteed; you may lose money by investing in
the fund.

Common stocks, which are the fund's main type of investment, generally fluctuate
in value more than other investments. The fund expects a close correlation
between its performance and that of the S&P 500 Index in both rising and falling
markets. The fund's performance, however, will generally will not be identical
to that of the Index because of the fees and expenses borne by the fund and
investor purchases and sales of fund shares, which can occur daily.

More information about these and other risks of an investment in the fund is
provided below in "More About Risks and Investment Strategies." In particular,
see the following headings:

o     Equity Risk

o     Index Investment Risk

o     Derivatives Risk

o     Foreign Securities Risk

INFORMATION ON THE FUND'S RECENT INVESTMENT STRATEGIES AND HOLDINGS CAN BE FOUND
IN ITS CURRENT ANNUAL/SEMI-ANNUAL REPORTS (SEE BACK COVER FOR INFORMATION ON
ORDERING SUCH REPORTS).

RISK/RETURN BAR CHART AND TABLE

The following bar chart and table provide information about the fund's
performance and thus give some indication of the risks of an investment in the
fund.

The bar chart shows how the fund's performance has varied from year to year. The
chart shows Class Y shares because they have the longest performance history of
any class of fund shares. Unlike the other classes of shares, Class Y shares
have no sales charges.

The table that follows the chart shows the average annual returns over several
time periods for each class of the fund's shares. That table does reflect fund
sales charges. The table compares fund returns to returns on the S&P 500 Index,
a broad-based market index that is unmanaged and that, therefore, does not
include any sales charges or expenses.

The fund's past performance does not necessarily indicate how the fund will
perform in the future.

* The fund and Mitchell Hutchins have entered into an expense reimbursement
agreement. Mitchell Hutchins has agreed to reimburse the fund to the extent that
the fund's expenses through the end of the current fiscal year otherwise would
exceed the "Net Expenses" rates for each class shown above. The fund has agreed
to repay Mitchell Hutchins for those reimbursed expenses if it can do so over
the following three years without causing the fund's expenses in any of those
three years to exceed those "Net Expenses" rates.


EXAMPLE

This example is intended to help you compare the cost of investing in the fund
with the cost of investing in other mutual funds.

This example assumes that you invest $10,000 in the fund for the time periods
indicated and then redeem all of your shares at the end of those periods unless
otherwise stated. The example also assumes that your investment has a 5% return
each year and that the fund's operating expenses remain the same, except for the
one year period when the fund's expenses are lower due to its reimbursement
agreement with Mitchell Hutchins. Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

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

                  MORE ABOUT RISKS AND INVESTMENT STRATEGIES
                  ------------------------------------------

PRINCIPAL RISKS

The main risks of investing in the fund are described below. Other risks of
investing in the fund, along with further detail about some of the risks
described below, are discussed in the fund's Statement of Additional Information
("SAI"). Information on how you can obtain the SAI is on the back cover of this
prospectus.

EQUITY RISK. The prices of common stocks and other equity securities generally
fluctuate more than those of other investments. They reflect changes in the
issuing company's financial condition and changes in the overall market. Common
stocks generally represent the riskiest investment in a company. The fund may
lose a substantial part, or even all, of its investment in a company's stock.

INDEX INVESTMENT RISK. The fund expects a close correlation between its
performance and that of the S&P 500 Index in both rising and falling markets.
While the fund attempts to replicate, before deduction of fees and operating
expenses, the investment results of theIndex, the fund's investment results
generally will not be identical to those of the Index. Deviations from the
performance of the Index may result from shareholder purchases and sales of
shares that can occur daily. In addition, the fund must pay fees and expenses
that are not borne by the Index.

DERIVATIVES RISK. The value of "derivatives" - so-called because their value
"derives" from the value of an underlying asset, reference rate or index may
rise or fall more rapidly than other investments. For some derivatives, it is
possible for the fund to lose more than the amount it invested in the
derivative. Derivatives include options and futures contracts that may be used
to simulate full investment in the S&P 500 Index.

FOREIGN SECURITIES RISK.   The S&P 500 Index includes some U.S.
dollar-denominated foreign securities.  Foreign securities involve risks that
normally are not associated with securities of U.S. issuers.  These include
risks relating to political, social and economic developments abroad and
differences between U.S. and foreign regulatory requirements and market
practices.


ADDITIONAL RISKS

YEAR 2000 RISK. The fund could be adversely affected by problems relating to the
inability of computer systems used by Mitchell Hutchins and the fund's other
service providers to recognize the year 2000. While year 2000-related computer
problems could have a negative effect on the fund, Mitchell Hutchins is working
to avoid these problems with respect to its own computer systems and to obtain
assurances from service providers that they are taking similar steps.

Similarly, the companies in which the fund invests and trading systems used by
the fund could be adversely affected by this issue. The ability of a company or
trading system to respond successfully to the issue requires both technological
sophistication and diligence, and there can be no assurance that any steps taken
will be sufficient to avoid an adverse impact on the fund.

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



FLEXIBLE PRICING
- ----------------

The fund offers three classes of shares - Class A, Class C and Class Y. Each
class has different sales charges and ongoing expenses. You can choose the class
that is best for you, based on how much you plan to invest in the fund and how
long you plan to hold your fund investment. Class Y shares are only available to
certain types of investors.


The fund has adopted a plan under rule 12b-1 for its Class A and Class C shares
that allows it to pay service and (for Class C shares) distribution fees for the
sale of its shares and services provided to shareholders. Because the 12b-1
distribution fees for Class C shares are paid out of the fund's assets on an
ongoing basis, over time they will increase the cost of your investment and may
cost you more than if you paid a front-end sale charge.


CLASS A SHARES

Class A shares have a front-end sales charge that is included in the offering
price of the Class A shares. This sales charge is not invested in the fund.
Class A shares pay an annual 12b-1 service fee of 0.25% of average net assets,
but they pay no 12b-1 distribution fees. The ongoing expenses for Class A shares
are lower than for Class C shares.

The Class A sales charges for the fund are described in the following table.

</TABLE>



(1)   A contingent deferred sales charge of 0.50% of the shares' offering price
      or the net asset value at the time of sale by the shareholder, whichever
      is less, is charged on sales of shares made within one year of the
      purchase date. Class A shares representing reinvestment of dividends are
      not subject to this 0.50% charge. Withdrawals in the first year after
      purchase of up to 12% of the value of the fund account under the funds'
      Systematic Withdrawal Plan are not subject to this charge.

(2)   Mitchell Hutchins pays 0.50% to PaineWebber.

SALES CHARGE REDUCTIONS AND WAIVERS. You may qualify for a lower sales charge if
you already own Class A shares of a PaineWebber mutual fund. You can combine the
value of Class A shares that you own in other PaineWebber funds and the purchase
amount of the Class A shares of the PaineWebber fund that you are buying.

You may also qualify for a lower sales charge if you combine your purchases with
those of:

o     your spouse, parents or children under age 21;

o     your Individual Retirement Accounts (IRAs);

o     certain employee benefit plans, including 401(k) plans;

o     a company that you control;

o     a trust that you created;

o     Uniform Gifts to Minors Act/Uniform Transfers to Minors Act accounts
      created by you or by a group of investors for your children; or

o     accounts with the same adviser.

You may qualify for a complete waiver of the sales charge if you:

o     Are an employee of PaineWebber or its affiliates or the spouse, parent
      or child under age 21 of a PaineWebber employee;

o     Buy these shares through a PaineWebber Financial Advisor who was formerly
      employed as an investment executive with a competing brokerage firm that
      was registered as a broker-dealer with the SEC, and

      -     you were the Financial Advisor's client at the competing brokerage
            firm;

      -     within 90 days of buying shares in the fund, you sell shares of one
            or more mutual funds that were principally underwritten by the
            competing brokerage firm or its affiliates, and you either paid a
            sales charge to buy those shares, pay a contingent deferred sales
            charge when selling them or held those shares until the contingent
            deferred sales charge was waived; and

      -     you purchase an amount that does not exceed the total amount of
            money you received from the sale of the other mutual fund;

o     Acquire these shares through the reinvestment of dividends of a
      PaineWebber unit investment trust;

o     Are a 401(k) or 403(b) qualified employee benefit plan with 50 or more
      eligible employees in the plan or at least $1 million in assets; or

o     Are a participant in the PaineWebber Members Onlysm Program. For
      investments made pursuant to this waiver, Mitchell Hutchins may make
      payments out of its own resources to PaineWebber and to participating
      membership organizations in a total amount not to exceed 1% of the amount
      invested.

NOTE: See the fund's SAI for some other sales charge waivers. If you think you
qualify for any sales charge reductions or waivers, you will need to provide
documentation to PaineWebber or the fund. For more information, you should
contact your PaineWebber Financial Advisor or correspondent firm or call
1-800-647-1568. If you want information on the fund's Systematic Withdrawal
Plan, see the SAI or contact your PaineWebber Financial Advisor or correspondent
firm.

CLASS C SHARES

Class C shares have a level load sales charge in the form of ongoing 12b-1
distribution fees. When you purchase Class C shares, we will invest 100% of your
purchase in fund shares.

Class C shares pay an annual 12b-1 distribution fee of 0.75% of average net
assets, as well as an annual 12b-1 service fee of 0.25% of average net assets.
Over time these fees will increase the cost of your investment and may cost you
more than if you paid a front-end sales charge. Class C shares do not convert to
another class of shares. This means that you will pay the 12b-1 fees for as long
as you own your shares.

                                       8
<PAGE>

Class C shares also have a contingent deferred sales charge. You may have to pay
the deferred sales charge if you sell your shares within one year of the date
you purchased them. We calculate the deferred sales charge on sales of Class C
shares by multiplying 1.00% by the lesser of the net asset value of the Class C
shares at the time of purchase or the net asset value at the time of sale. We
will not impose the deferred sales charge on Class C shares representing
reinvestment of dividends or on withdrawals in the first year after purchase, of
up to 12% of the value of your Class C shares under the Systematic Withdrawal
Plan.

NOTE:  If you want information on the fund's Systematic Withdrawal Plan, see
the SAI or contact your PaineWebber Financial Advisor or correspondent firm.

CLASS Y SHARES

Class Y shares have no sales charge. Only specific types of investors can
purchase Class Y shares. You may be eligible to purchase Class Y shares if you:

o     Buy shares through PaineWebber's PACE Multi-Advisor Program;

o     Buy $10 million or more of PaineWebber fund shares at any one time;

o     Are a qualified retirement plan with 5,000 or more eligible employees or
      $50 million in assets; or

o     Are an investment company advised by PaineWebber or an affiliate of
      PaineWebber.

Class Y shares do not pay ongoing distribution or service fees or sales charges.
The ongoing expenses for Class Y shares are the lowest for all the classes.

BUYING SHARES
- -------------

If you are a PaineWebber client, or a client of a PaineWebber correspondent
firm, you can purchase fund shares through your Financial Advisor. Otherwise,
you can invest in the funds through the fund's transfer agent, PFPC Inc. You can
obtain an application by calling 1-800-647-1568. You must complete and sign the
application and mail it, along with a check, to:

      PFPC Inc.
      Attn.: PaineWebber Mutual Funds
      P.O. Box 8950
      Wilmington, DE  19899.

If you wish to invest in other PaineWebber Funds, you can do so by:

o     Contacting your Financial Advisor (if you have an account at PaineWebber
      or at a PaineWebber correspondent firm);

o     Mailing an application with a check; or

o     Opening an account by exchanging shares from another PaineWebber fund.

You do not have to complete an application when you make additional investments
in the same fund.

The fund and Mitchell Hutchins reserve the right to reject a purchase order or
suspend the offering of shares.

MINIMUM INVESTMENTS

  To open an account .....................................$1,000
  To add to an account ...................................$  100

The fund may waive or reduce these amounts for:

o     Employees of PaineWebber or its affiliates; or

o     Participants in certain pension plans, retirement accounts, unaffiliated
      investment programs or the funds' automatic investment plans.

FREQUENT TRADING The interests of the fund's long-term shareholders and its
ability to manage its investments may be adversely affected when its shares are
repeatedly bought and sold in response to short-term market fluctuations -- also
known as "market timing." When large dollar amounts are involved, the fund may
have difficulty implementing long-term investment strategies, because it cannot
predict how much cash it will have to invest. Market timing also may force the
fund to sell portfolio securities at disadvantageous times to raise the cash
needed to buy a market timer's fund shares. These factors may hurt the fund's
performance and its shareholders. When Mitchell Hutchins believes frequent
trading would have a disruptive effect on the fund's ability to manage its
investments, Mitchell Hutchins and the fund may reject purchase orders and
exchanges into the fund by any person, group or account that Mitchell Hutchins
believes to be a market timer. The fund may notify the market timer that a
purchase order or an exchange has been rejected after the day the order is
placed.

SELLING SHARES
- --------------

You can sell your fund shares at any time. If you own more than one class of
shares, you should specify which class you want to sell. If you do not, the fund
will assume that you want to sell shares in the following order: Class A, then
Class C and last, Class Y.

If you want to sell shares that you purchased recently, the fund may delay
payment until it verifies that it has received good payment. If you purchased
shares by check, this can take up to 15 days.

If you have an account with PaineWebber or a PaineWebber correspondent firm, you
can sell shares by contacting your Financial Advisor.

PaineWebber   S&P 500 Index Fund
- --------------------------------------------------------------------------------


If you do not have an account at PaineWebber or a correspondent firm, and you
bought your shares through the transfer agent, you can sell your shares by
writing to the fund's transfer agent. Your letter must include:

o     Your name and address;

o     The fund's name;

o     The fund account number;

o     The dollar amount or number of shares you want to sell; and

o     A guarantee of each registered owner's signature. A signature guarantee
      may be obtained from a financial institution, broker, dealer or clearing
      agency that is a participant in one of the medallion programs recognized
      by the Securities Transfer Agents Association. These are: Securities
      Transfer Agents Medallion Program (STAMP), Stock Exchanges Medallion
      Program (SEMP) and the New York Stock Exchange Medallion Signature Program
      (MSP). The fund will not accept signature guarantees that are not a part
      of these programs.

Mail the letter to:

      PFPC Inc.
      Attn.: PaineWebber Mutual Funds
      P.O. Box 8950
      Wilmington, DE  19899.

If you sell Class A shares and then repurchase Class A shares of the fund within
365 days of the sale, you can reinstate your account without paying a sales
charge.

It costs the fund money to maintain shareholder accounts. Therefore, the fund
reserves the right to repurchase all shares in any account that has a net asset
value of less than $500. If the fund elects to do this with your account, it
will notify you that you can increase the amount invested to $500 or more within
60 days. The fund will not repurchase shares in accounts that fall below $500
solely because of a decrease in the fund's net asset value.

EXCHANGING SHARES
- -----------------

You may exchange Class A or Class C shares of the fund for shares of the same
class of most other PaineWebber funds. You may not exchange Class Y shares.

You will not pay either a front-end sales charge or a deferred sales charge when
you exchange shares. However, you may have to pay a deferred sales charge if you
later sell the shares you acquired in the exchange. A fund will use the date
that you purchased the shares in the first fund to determine whether you must
pay a deferred sales charge when you sell the shares in the acquired fund.

Other PaineWebber funds may have different minimum investment amounts. You may
not be able to exchange your shares if your exchange is not as large as the
minimum investment amount in that other fund.

You may exchange shares of one fund for shares of another fund only after the
first purchase has settled and the first fund has received your payment.

PAINEWEBBER CLIENTS. If you bought your shares through PaineWebber or a
correspondent firm, you may exchange your shares by placing an order with your
PaineWebber Financial Advisor.

OTHER INVESTORS.  If you are not a PaineWebber client, you may exchange your
shares by writing to the fund's transfer agent.  You must include:

o     Your name and address;

o     The name of the fund whose shares you are selling and the name of the fund
      whose shares you want to buy;

o     Your account number;

o     How much you are exchanging (by dollar amount or by number of shares to be
      sold); and

o     A guarantee of your signature. (See "Buying Shares" for information on
      obtaining a signature guarantee.)

A fund may modify or terminate the exchange privilege at any time.


PRICING AND VALUATION
- ---------------------

The price at which you may buy, sell or exchange fund shares is based on net
asset value per share. The fund calculates net asset value on days that the New

PaineWebber   S&P 500 Index Fund
- --------------------------------------------------------------------------------


York Stock Exchange is open. The fund calculates net asset value separately for
each class as of the close of regular trading on the NYSE (generally, 4:00 p.m.,
Eastern time). The NYSE normally is not open, and the fund does not price its
shares, on national holidays and on Good Friday. If trading on the NYSE is
halted for the day before 4:00 p.m., Eastern time, the fund's net asset value
per share will be calculated as of the time trading was halted.

Your price for buying, selling or exchanging shares will be based on the net
asset value that is next calculated after the fund accepts your order. If you
place your order through PaineWebber, your PaineWebber Financial Advisor is
responsible for making sure that your order is promptly sent to the fund.

You should keep in mind that a front-end sales charge may be applied to your
purchase if you buy Class A shares. A deferred sales charge may be applied when
you sell Class C shares.

The fund calculates its net asset value based on the current market value for
its portfolio securities. The fund normally obtains market values for its
securities from independent pricing services that use reported last sales
prices, current market quotations or valuations from computerized "matrix"
systems that derive values based on comparable securities. If a market value is
not available from an independent pricing source for a particular security, that
security is valued at a fair value determined by or under the direction of the
fund's board. The fund normally uses the amortized cost method to value bonds
that will mature in 60 days or less.

OTHER INFORMATION

The fund has received an exemptive order from the SEC that permits the board to

board may implement it. As of the date of this prospectus, the fund has not
asked shareholders to do so.

                             DIVIDENDS AND TAXES
                             -------------------



DIVIDENDS

The fund normally declares and pays dividends and distributes any gains
annually.

Classes with higher expenses are expected to have lower dividends. For example,
Class C shares are expected to have the lowest dividends of any class of the
fund's shares, while Class Y shares are expected to have the highest.

You will receive dividends in additional shares of the same class unless you
elect to receive them in cash. Contact your Financial Advisor at PaineWebber or
one of its correspondent firms if you prefer to receive dividends in cash.

TAXES

The dividends that you receive from the fund generally are subject to federal
income tax regardless of whether you receive them in additional fund shares or
in cash. If you hold fund shares through a tax-exempt account or plan, such as
an IRA or 401(k) plan, dividends on your shares generally will not be subject to
tax.

When you sell fund shares, you generally will be subject to federal income tax
on any gain you realize. If you exchange the fund's shares for shares of another
PaineWebber mutual fund, the transaction will be treated as a sale of the first
fund's shares, and any gain will be subject to federal income tax.

The fund expects that its dividends will include capital gain distributions. The
distribution of capital gains may be taxed at a lower rate than ordinary income,
depending on whether the fund held the assets that generated the gains for more
than 12 months. The fund will tell you how you should treat its dividends for
tax purposes.

                      THE FUND AND ITS INVESTMENT POLICIES

      The fund's  investment  objective is to replicate  the total return of the
Standard & Poor's 500 Composite  Stock Index ("S&P 500 Index"),  before fees and
expenses. The fund seeks to achieve its objective by investing substantially all
of its assets in common  stocks  issued by companies in the S&P 500 Index and in
related  derivatives,  such as options  and  futures  contracts,  that  simulate
investment in the Index.  The fund invests at least 65% of its total assets in a
substantial majority of the common stocks issued by companies represented in the
S&P 500 Index.

      The fund invests in  substantially  all 500 stocks in the S&P 500 Index in
proportion to their weighting in the Index and, ordinarily,  invests in at least
450  stocks  that  are  represented  in  the  Index.  If  the  fund  experiences
exceptional  levels of  purchases  or  redemptions,  the fund may be  delayed in
rebalancing  its  portfolio  to reflect  the  weightings  of the  common  stocks
reflected  in the Index or may hold less than 450 stocks of the Index.  The fund
will be rebalanced as soon as practicable to reflect the common stock weightings
represented  in the Index and may use  derivative  instruments  to replicate the
weightings of the Index in the interim.  From time to time,  adjustments  may be
made in the fund's  investments  because of  changes in the  composition  of the
Index.  The fund will invest 25% or more of its total  assets in  securities  of
issuers in the same  industry if necessary to  replicate  the  weighting of that
particular industry in the S&P 500 Index.

      The fund  attempts  to  achieve a  correlation,  over  time,  between  the
performance of its  investments  and that of the S&P 500 Index of at least 0.95,
before  deduction of fees and expenses.  A correlation  of 1.00 would  represent
perfect  correlation  between the fund's  performance and that of the Index. The
performance of the fund versus that of the Index is compared at least weekly. If
an unexpected  tracking error develops,  the fund's portfolio will be rebalanced
to bring it into line with the Index.  There can be no  assurance  that the fund
will achieve its expected results.

      The fund is  authorized to invest up to 35% of its total assets in cash or
money market instruments, although it expects these investments will represent a
much smaller  portion of its total assets under normal  circumstances.  The fund
may invest up to 15% of its net assets in illiquid  securities.  It may purchase
securities  on a  when-issued  basis and may  purchase  or sell  securities  for
delayed  delivery.  The  fund may lend its  portfolio  securities  to  qualified
broker-dealers  or  institutional  investors  in an  amount up to 33 1/3% of its
assets.  The fund may borrow money for  temporary  or  emergency  purposes in an
amount  up to  33  1/3 % of  its  total  assets,  including  reverse  repurchase
agreements. The fund also may invest in securities of other investment companies
[and may sell securities short "against the box."]

            THE FUND'S INVESTMENTS, RELATED RISKS AND LIMITATIONS

      The following  supplements  the  information  contained in the  Prospectus
concerning the fund's investment  policies and limitations.  Except as indicated
in the  Prospectus or this SAI,  there are no policy  limitations  on the fund's
ability to use the investments or techniques discussed in these documents.

      EQUITY  SECURITIES.  Equity  securities  (referred  to as  "stocks" in the
Prospectus) include common stocks, most preferred stocks and securities that are
convertible  into them,  including  common stock  purchase  warrants and rights,
equity interests in trusts, partnerships,  joint ventures or similar enterprises
and depository  receipts.  Common stocks,  the most familiar type,  represent an
equity (ownership) interest in a corporation.

      Preferred  stock has certain fixed income  features,  like a bond,  but is
actually  equity in a company,  like common stock.  Convertible  securities  may
include debentures, notes and preferred equity securities, that may be converted
into or  exchanged  for a  prescribed  amount of  common  stock of the same or a
different  issuer  within a  particular  period of time at a specified  price or
formula.  Depository  receipts  typically are issued by banks or trust companies
and evidence ownership of underlying equity securities.

      While  past  performance   does  not  guarantee  future  results,   equity
securities historically have provided the greatest long-term growth potential in
a company.  However, their prices generally fluctuate more than other securities

                                       2
<PAGE>


and reflect changes in a company's financial condition and in overall market and
economic  conditions.  Common stocks generally represent the riskiest investment
in a company.  It is possible  that the fund may  experience  a  substantial  or
complete loss on an individual equity investment.

      MONEY MARKET INSTRUMENTS.  The fund may invest in money market instruments
for temporary  purposes or for cash management  purposes.  These instruments are
short-term debt obligations and similar  securities and include:  (1) securities
issued or guaranteed as to interest and principal by the U.S.  government or one
of its  agencies  or  instrumentalities;  (2) debt  obligations  of U.S.  banks,
savings  associations,  insurance companies and mortgage bankers, (3) commercial
paper and other short-term obligations of corporations, partnerships, trusts and
similar entities; (4) repurchase agreements regarding any of the foregoing;  and
(6) investment company securities.  Money market instruments include longer-term
bonds that have variable interest rates or other special features that give them
the financial characteristics of short-term debt. In addition, the fund may hold
cash and may invest in  participation  interests in the money market  securities
mentioned above without limitation.

      INVESTING  IN  FOREIGN  SECURITIES.  To the  extent  the fund  holds  U.S.
dollar-denominated  securities of foreign  issuers,  the  securities  may not be
registered with the Securities and Exchange Commission ("SEC"),  and the issuers
thereof may not be subject to its reporting requirements. Accordingly, there may
be less publicly available information  concerning foreign issuers of securities
held by the fund than is available concerning U.S. companies.  Foreign companies
are  not  generally  subject  to  uniform  accounting,  auditing  and  financial
reporting  standards or to other  regulatory  requirements  comparable  to those
applicable to U.S. companies.

      Investing in foreign securities  involves more risks than investing in the
United States.  The value of foreign  securities is subject to social,  economic
and political  developments in the countries where the companies  operate and to
changes  in  foreign  currency  values,  as well as  risks  resulting  from  the
differences  between  the  regulations  to which U.S.  and  foreign  issuers are
subject.   These  risks  may  include   expropriation,   confiscatory  taxation,
withholding  taxes on interest  and/or  dividends,  limitations on the use of or
transfer  of fund  assets and  political  or social  instability  or  diplomatic
developments.  Moreover,  individual  foreign  economies may differ favorably or
unfavorably  from the U.S.  economy in such respects as growth of gross national
product, rate of inflation, capital reinvestment,  resource self-sufficiency and
balance of payments position.  In those European countries that have begun using
the  Euro as a  common  currency  unit,  individual  national  economies  may be
adversely  affected by the  inability  of national  governments  to use monetary
policy to address their own economic or political concerns.

      The fund may  invest in  foreign  securities  only if the  securities  are
traded in the U.S. directly or through American  Depository  Receipts  ("ADRs").
ADRs are receipts  typically  issued by a U.S. bank or trust company  evidencing
ownership of the underlying  securities.  They generally are in registered form,
are denominated in U.S. dollars and are designed for use in the U.S.  securities
markets. For purposes of the fund's investment policies, ADRs are deemed to have
the same  classification as the underlying  securities they represent.  Thus, an
ADR representing ownership of common stock will be treated as common stock.

      ADRs are publicly  traded on exchanges or OTC in the United States and are
issued through  "sponsored" or  "unsponsored"  arrangements.  In a sponsored ADR
arrangement, the foreign issuer assumes the obligation to pay some or all of the
depository's  transaction fees,  whereas under an unsponsored  arrangement,  the
foreign issuer assumes no obligations and the depository's  transaction fees are
paid directly by the ADR holders. In addition,  less information is available in
the United States about an unsponsored ADR than about a sponsored ADR.

      Investment  income on  certain  foreign  securities  in which the fund may
invest may be subject to foreign  withholding  or other taxes that could  reduce
the return on these  securities.  Tax  treaties  between  the United  States and
foreign countries,  however, may reduce or eliminate the amount of foreign taxes
to which the fund would be subject.

      REPURCHASE AGREEMENTS. Repurchase agreements are transactions in which the
fund purchases  securities or other obligations from a bank or securities dealer
(or its affiliate) and simultaneously commits to resell them to the counterparty
at an agreed-upon date or upon demand and at a price reflecting a market rate of
interest unrelated to the coupon rate or maturity of the purchased  obligations.
The  fund  maintains  custody  of the  underlying  obligations  prior  to  their

                                       3
<PAGE>

repurchase,   either  through  its  regular   custodian  or  through  a  special
"tri-party" custodian or sub-custodian that maintains separate accounts for both
the fund and its  counterparty.  Thus, the obligation of the counterparty to pay
the repurchase price on the date agreed to or upon demand is, in effect, secured
by such  obligations.  Repurchase  agreements carry certain risks not associated
with direct  investments  in  securities,  including  a possible  decline in the
market value of the underlying obligations. If their value becomes less than the
repurchase price, plus any agreed-upon  additional amount, the counterparty must
provide  additional  collateral so that at all times the  collateral is at least
equal to the  repurchase  price  plus any  agreed-upon  additional  amount.  The
difference  between  the total  amount to be  received  upon  repurchase  of the
obligations and the price that was paid by the fund upon  acquisition is accrued
as interest and included in its net  investment  income.  Repurchase  agreements
involving  obligations other than U.S. government securities (such as commercial
paper and corporate  bonds) may be subject to special risks and may not have the
benefit of certain protections in the event of the counterparty's insolvency. If
the seller or guarantor becomes insolvent, the fund may suffer delays, costs and
possible  losses in connection  with the  disposition  of  collateral.  The fund
intends  to  enter  into  repurchase  agreements  only  with  counterparties  in
transactions believed by Mitchell Hutchins to present minimum credit risks.

      REVERSE REPURCHASE  AGREEMENTS.  Reverse repurchase agreements involve the
sale  of  securities  held  by the  fund  subject  to the  fund's  agreement  to
repurchase the  securities at an agreed-upon  date or upon demand and at a price
reflecting a market rate of interest.  Reverse repurchase agreements are subject
to the fund's  limitation on borrowings  and may be entered into only with banks
and securities dealers or their affiliates. While a reverse repurchase agreement
is  outstanding,  the fund  will  maintain,  in a  segregated  account  with its
custodian,  cash or liquid  securities,  marked to market daily, in an amount at
least equal to its obligations under the reverse repurchase agreement.

      Reverse  repurchase  agreements  involve  the risk  that the  buyer of the
securities  sold by the fund might be unable to deliver them when the fund seeks
to  repurchase.  In the  event  that the  buyer of  securities  under a  reverse
repurchase  agreement files for bankruptcy or becomes  insolvent,  such buyer or
trustee or receiver may receive an  extension  of time to  determine  whether to
enforce the fund's  obligation to repurchase the securities,  and the fund's use
of  the  proceeds  of  the  reverse  repurchase  agreement  may  effectively  be
restricted pending such decision.

      ILLIQUID  SECURITIES.  The term "illiquid  securities" for purposes of the
Prospectus and SAI means securities that cannot be disposed of within seven days
in the ordinary course of business at approximately the amount at which the fund
has  valued  the  securities  and  includes,   among  other  things,   purchased
over-the-counter options, repurchase agreements maturing in more than seven days
and restricted  securities other than those Mitchell Hutchins has determined are
liquid pursuant to guidelines  established by the fund's board.  The assets used
as cover for  over-the-counter  options  written by the fund will be  considered
illiquid unless the  over-the-counter  options are sold to qualified dealers who
agree that the fund may repurchase any over-the-counter  options they write at a
maximum price to be calculated by a formula set forth in the option  agreements.
The cover for an over-the-counter option written subject to this procedure would
be  considered  illiquid  only to the extent that the maximum  repurchase  price
under the formula exceeds the intrinsic  value of the option.  To the extent the
fund  invests in illiquid  securities,  it may not be able to readily  liquidate
such  investments  and may have to sell other  investments if necessary to raise
cash to meet its obligations. The lack of a liquid secondary market for illiquid
securities  may make it more  difficult  for the fund to assign a value to those
securities for purposes of valuing its portfolio and  calculating  its net asset
value.

      Restricted  securities are not registered under the Securities Act of 1933
and may be sold only in privately  negotiated or other exempted  transactions or
after a 1933 Act registration statement has become effective. Where registration
is required,  the fund may be  obligated to pay all or part of the  registration
expenses and a  considerable  period may elapse between the time of the decision
to sell  and the time the fund  may be  permitted  to sell a  security  under an
effective  registration  statement.  If,  during such a period,  adverse  market
conditions  were to develop,  the fund might obtain a less favorable  price than
prevailed when it decided to sell.

      However, not all restricted securities are illiquid. A large institutional
market  has  developed  for  many  U.S.  and  foreign  securities  that  are not
registered under the 1933 Act.  Institutional  investors generally will not seek
to sell these  instruments to the general public,  but instead will often depend


                                       4
<PAGE>

either  on  an  efficient   institutional  market  in  which  such  unregistered
securities can be readily resold or on an issuer's ability to honor a demand for
repayment.  Therefore, the fact that there are contractual or legal restrictions
on resale to the general public or certain  institutions  is not  dispositive of
the liquidity of such investments.

      Institutional  markets for restricted  securities also have developed as a
result of Rule 144A,  which  establishes a "safe  harbor" from the  registration
requirements  of the 1933 Act for  resales of certain  securities  to  qualified
institutional  buyers.  Such markets include  automated systems for the trading,
clearance  and  settlement  of  unregistered  securities of domestic and foreign
issuers,  such as the PORTAL  System  sponsored by the National  Association  of
Securities  Dealers,  Inc. An  insufficient  number of  qualified  institutional
buyers interested in purchasing Rule 144A-eligible restricted securities held by
the fund,  however,  could affect adversely the  marketability of such portfolio
securities,  and the fund might be unable to dispose of such securities promptly
or at favorable prices.

      The board has delegated the function of making  day-to-day  determinations
of liquidity to Mitchell Hutchins pursuant to guidelines  approved by the board.
Mitchell  Hutchins takes into account a number of factors in reaching  liquidity
decisions,  including  (1) the  frequency  of trades for the  security,  (2) the
number of dealers that make quotes for the  security,  (3) the number of dealers
that have  undertaken to make a market in the security,  (4) the number of other
potential  purchasers  and (5) the  nature of the  security  and how  trading is
effected (e.g., the time needed to sell the security, how bids are solicited and
the  mechanics  of  transfer).  Mitchell  Hutchins  monitors  the  liquidity  of
restricted  securities in the fund's portfolio and reports  periodically on such
decisions to the board.

      LENDING  OF  PORTFOLIO  SECURITIES.  The  fund is  authorized  to lend its
portfolio securities to broker-dealers or institutional  investors that Mitchell
Hutchins deems qualified. Lending securities enables the fund to earn additional
income, but could result in a loss or delay in recovering these securities.  The
borrower of the fund's portfolio securities must maintain acceptable  collateral
with the fund's  custodian in an amount,  marked to market daily, at least equal
to the  market  value  of the  securities  loaned,  plus  accrued  interest  and
dividends.  Acceptable collateral is limited to cash, U.S. government securities
and irrevocable  letters of credit that meet certain  guidelines  established by
Mitchell  Hutchins.  The fund  may  reinvest  cash  collateral  in money  market
instruments or other short-term liquid  investments.  In determining  whether to
lend  securities  to  a  particular  broker-dealer  or  institutional  investor,
Mitchell Hutchins will consider, and during the period of the loan will monitor,
all relevant  facts and  circumstances,  including the  creditworthiness  of the
borrower.  The fund will retain  authority to terminate  any of its loans at any
time. The fund may pay reasonable fees in connection with a loan and may pay the
borrower or placing  broker a negotiated  portion of the interest  earned on the
reinvestment  of  cash  held  as  collateral.  The  fund  will  receive  amounts
equivalent to any dividends,  interest or other  distributions on the securities
loaned.  The fund will regain record ownership of loaned  securities to exercise
beneficial rights,  such as voting and subscription  rights, when regaining such
rights is considered to be in the fund's interest.

      Pursuant  to  procedures   adopted  by  the  board  governing  the  fund's
securities  lending  program,  PaineWebber has been retained to serve as lending
agent for the fund. The board also has authorized the payment of fees (including
fees calculated as a percentage of invested cash  collateral) to PaineWebber for
these services.  The board  periodically  reviews all portfolio  securities loan
transactions for which PaineWebber has acted as lending agent.  PaineWebber also
has been approved as a borrower under the fund's securities lending program.

      WARRANTS.  Warrants are securities permitting,  but not obligating,  their
holder to subscribe for other  securities or commodities.  Warrants do not carry
with them the right to dividends or voting rights with respect to the securities
that they entitle their holder to purchase, and they do not represent any rights
in the  assets of the  issuer.  As a result,  warrants  may be  considered  more
speculative than certain other types of investments. In addition, the value of a
warrant does not necessarily change with the value of the underlying securities,
and a  warrant  ceases  to  have  value  if it is  not  exercised  prior  to its
expiration date.

      WHEN-ISSUED  AND  DELAYED  DELIVERY  SECURITIES.  The fund may  purchase a
security on a when-issued  basis or may purchase or sell  securities for delayed
delivery, I.E., for issuance or delivery to or by the fund later than the normal
settlement  date for such  securities  at a stated  price  and  yield.  The fund
generally  would not pay for such  securities or start earning  interest on them
until they are received.  However,  when the fund  undertakes a  when-issued  or


                                       5
<PAGE>

delayed  delivery  obligation,  it  immediately  assumes the risks of ownership,
including  the risks of price  fluctuation.  Failure  of the issuer to deliver a
security  purchased by the fund on a when-issued  or delayed  delivery basis may
result in the fund's  incurring or missing an opportunity to make an alternative
investment.  Depending on market conditions,  the fund's when-issued and delayed
delivery  purchase  commitments  could cause its net asset value per share to be
more  volatile,  because  such  securities  may increase the amount by which the
fund's total assets,  including the value of  when-issued  and delayed  delivery
securities held by the fund, exceeds its net assets.

      A  security  purchased  on a  when-issued  or  delayed  delivery  basis is
recorded as an asset on the commitment  date and is subject to changes in market
value,  generally  based upon  changes  in the level of  interest  rates.  Thus,
fluctuation  in the value of the security from the time of the  commitment  date
will  affect  the  fund's  net asset  value.  When the fund  agrees to  purchase
securities on a when-issued or delayed delivery basis, its custodian  segregates
assets  to cover the  amount  of the  commitment  See "The  Fund's  Investments,
Related Risks and Limitations--Segregated Accounts." The fund may sell the right
to  acquire  the  security  prior to  delivery  if  Mitchell  Hutchins  deems it
advantageous to do so, which may result in a gain or loss to the fund.

      SEGREGATED  ACCOUNTS.  When the fund enters into certain  transactions  to
make future payments to third parties, including the purchase of securities on a
when-issued  or  delayed  delivery  basis,  it will  maintain  with an  approved
custodian in a segregated  account cash or liquid  securities,  marked to market
daily, in an amount at least equal to the fund's  obligation or commitment under
such  transactions.  As  described  below  under  "Strategies  Using  Derivative
Instruments,"  segregated  accounts  may also be  required  in  connection  with
certain transactions involving options and futures contracts.

      INVESTMENT LIMITATIONS OF THE FUND

      FUNDAMENTAL INVESTMENT  LIMITATIONS.  The following fundamental investment
limitations  cannot be changed for the fund without the affirmative  vote of the
lesser of (a) more than 50% of the outstanding  shares of the fund or (b) 67% or
more of the fund's shares present at a shareholders' meeting if more than 50% of
the  outstanding  fund  shares are  represented  at the  meeting in person or by
proxy. If a percentage restriction is adhered to at the time of an investment or
transaction,  a later increase or decrease in percentage resulting from a change
in  values  of  portfolio  securities  or  amount  of total  assets  will not be
considered a violation of any of the following limitations.

      The fund will not:

          (1) purchase  securities of any one issuer if, as a result,  more than
    5% of the fund's total assets would be invested in securities of that issuer
    or the  fund  would  own or hold  more  than 10% of the  outstanding  voting
    securities of that issuer,  except that up to 25% of the fund's total assets
    may be  invested  without  regard to this  limitation,  and except that this
    limitation  does not apply to  securities  issued or  guaranteed by the U.S.
    government,  its agencies and  instrumentalities  or to securities issued by
    other investment companies.

          The  following  interpretation  applies to, but is not a part of, this
    fundamental  restriction:  Mortgage- and asset-backed securities will not be
    considered  to  have  been  issued  by the  same  issuer  by  reason  of the
    securities   having  the  same  sponsor,   and  mortgage-  and  asset-backed
    securities issued by a finance or other special purpose  subsidiary that are
    not  guaranteed  by the parent  company will be considered to be issued by a
    separate issuer from the parent company.

          (2) purchase any  security  if, as a result of that  purchase,  25% or
    more of the fund's total assets would be invested in  securities  of issuers
    having their principal business activities in the same industry, except that
    this  limitation  does not  apply to  investments  in  securities  issued or
    guaranteed by the U.S.  government,  its agencies or instrumentalities or to
    municipal  securities  and provided that the fund will invest 25% or more of
    its total assets in  securities of issuers in the same industry if necessary
    to replicate the weighting of that particular industry in the S&P 500 Index.

          (3) issue senior securities or borrow money, except as permitted under
    the Investment  Company Act of 1940, as amended  ("Investment  Company Act")
    and then not in excess of 33-1/3% of the fund's total assets  (including the


                                       6
<PAGE>

    amount of the senior  securities  issued but reduced by any  liabilities not
    constituting  senior  securities)  at the time of the issuance or borrowing,
    except that the fund may borrow up to an  additional  5% of its total assets
    (not including the amount borrowed) for temporary or emergency purposes.

          (4) make  loans,  except  through  loans of  portfolio  securities  or
    through   repurchase   agreements,   provided  that  for  purposes  of  this
    restriction,  the acquisition of bonds, debentures, other debt securities or
    instruments, or participations or other interests therein and investments in
    government obligations,  commercial paper, certificates of deposit, bankers'
    acceptances  or similar  instruments  will not be considered the making of a
    loan.

          (5)  engage  in the  business  of  underwriting  securities  of  other
    issuers,  except  to the  extent  that  the  fund  might  be  considered  an
    underwriter  under  the  federal  securities  laws in  connection  with  its
    disposition of portfolio securities.

          (6)  purchase  or  sell  real  estate,   except  that  investments  in
    securities  of  issuers  that  invest  in real  estate  and  investments  in
    mortgage-backed  securities,  mortgage  participations  or other instruments
    supported by  interests  in real estate are not subject to this  limitation,
    and except that the fund may exercise  rights under  agreements  relating to
    such securities,  including the right to enforce  security  interests and to
    hold real  estate  acquired  by reason of such  enforcement  until that real
    estate can be liquidated in an orderly manner.

          (7) purchase or sell physical  commodities unless acquired as a result
    of owning securities or other instruments,  but the fund may purchase,  sell
    or enter into  financial  options and  futures,  forward  and spot  currency
    contracts,  swap  transactions  and other financial  contracts or derivative
    instruments.

      NON-FUNDAMENTAL   LIMITATIONS.  The  following  investment  restrictions
are  non-fundamental  and may be  changed  by the  vote of the  board  without
shareholder approval.

      The fund will not:

          (1) invest more than 15% of its net assets in illiquid securities.

          (2) purchase portfolio  securities while borrowings in excess of 5% of
    its total assets are outstanding.

          (3)  purchase  securities  on  margin,  except for  short-term  credit
    necessary for clearance of portfolio  transactions  and except that the fund
    may make margin deposits in connection with its use of financial options and
    futures,  forward and spot currency  contracts,  swap transactions and other
    financial contracts or derivative instruments.

          (4) engage in short sales of securities or maintain a short  position,
    except that the fund may (a) sell short  "against  the box" and (b) maintain
    short positions in connection with its use of financial options and futures,
    forward and spot currency  contracts,  swap transactions and other financial
    contracts or derivative instruments.

          (5) purchase securities of other investment  companies,  except to the
    extent  permitted  by the  Investment  Company  Act or under the terms of an
    exemptive  order granted by the SEC and except that this limitation does not
    apply to  securities  received or acquired as dividends,  through  offers of
    exchange, or as a result of reorganization, consolidation, or merger.

                     STRATEGIES USING DERIVATIVE INSTRUMENTS

      GENERAL DESCRIPTION OF DERIVATIVE INSTRUMENTS.  The fund may use a variety
of financial instruments ("Derivative Instruments"),  including certain options,
futures  contracts  (sometimes  referred to as "futures") and options on futures
contracts.  The fund may enter into transactions  involving one or more types of
Derivative  Instruments  under which the full value of its portfolio is at risk.


                                       7
<PAGE>

Under normal  circumstances,  however,  the fund's use of these instruments will
place at risk a much smaller  portion of its assets.  The particular  Derivative
Instruments that may be used by the fund are described below.

      The  fund  might  not  use  any   Derivative   Instruments  or  derivative
strategies,  and there can be no assurance that using any strategy will succeed.
If the fund is  incorrect in its judgment on market  values,  interest  rates or
other economic  factors in using a Derivative  Instrument or strategy,  the fund
may have lower net income and a net loss on the investment.

      OPTIONS ON SECURITIES.  A call option is a short-term contract pursuant to
which the purchaser of the option, in return for a premium, has the right to buy
the security  underlying the option at a specified  price at any time during the
term of the option or at  specified  times or at the  expiration  of the option,
depending on the type of option  involved.  The writer of the call  option,  who
receives the premium, has the obligation, upon exercise of the option during the
option term, to deliver the underlying  security against payment of the exercise
price. A put option is a similar  contract that gives its  purchaser,  in return
for a premium,  the right to sell the underlying  security at a specified  price
during the option term or at specified times or at the expiration of the option,
depending  on the type of option  involved.  The writer of the put  option,  who
receives the premium, has the obligation, upon exercise of the option during the
option term, to buy the underlying security at the exercise price.

      OPTIONS ON SECURITIES  INDICES. A securities index assigns relative values
to the  securities  included  in the index and  fluctuates  with  changes in the
market values of those  securities.  A securities  index option  operates in the
same way as a more  traditional  securities  option,  except that  exercise of a
securities  index  option is  effected  with cash  payment  and does not involve
delivery of securities.  Thus, upon exercise of a securities  index option,  the
purchaser  will  realize,  and the  writer  will  pay,  an  amount  based on the
difference  between the exercise  price and the closing price of the  securities
index.

      SECURITIES INDEX FUTURES CONTRACTS. A securities index futures contract is
a  bilateral  agreement  pursuant to which one party  agrees to accept,  and the
other party  agrees to make,  delivery of an amount of cash equal to a specified
dollar amount times the  difference  between the  securities  index value at the
close of trading of the contract and the price at which the futures  contract is
originally  struck. No physical delivery of the securities  comprising the index
is made. Generally, contracts are closed out prior to the expiration date of the
contract.

      OPTIONS ON FUTURES CONTRACTS.  Options on futures contracts are similar to
options on  securities,  except that an option on a futures  contract  gives the
purchaser  the right,  in return  for the  premium,  to assume a  position  in a
futures  contract (a long position if the option is a call and a short  position
if the  option is a put),  rather  than to  purchase  or sell a  security,  at a
specified price at any time during the option term. Upon exercise of the option,
the  delivery  of the  futures  position  to the  holder of the  option  will be
accompanied by delivery of the accumulated balance that represents the amount by
which the market price of the futures contract  exceeds,  in the case of a call,
or is less than,  in the case of a put, the exercise  price of the option on the
future. The writer of an option, upon exercise,  will assume a short position in
the case of a call and a long position in the case of a put.

      GENERAL DESCRIPTION OF STRATEGIES USING DERIVATIVE  INSTRUMENTS.  The fund
may use Derivative  Instruments to simulate full investment in the S&P 500 Index
while  retaining a cash  balance  for  management  purposes,  such as to provide
liquidity  to meet  anticipated  shareholder  sales of fund  shares and for fund
operating  expenses.  As part of its use of Derivative  Instruments for the cash
management  purposes,  the fund may attempt to reduce the risk of adverse  price
movements  ("hedge") in the securities of the S&P 500 Index while investing cash
received  from investor  purchases of fund shares or selling  securities to meet
shareholder redemptions.  The fund may also use Derivative Instruments to reduce
transaction costs and to facilitate trading.

      Hedging strategies can be broadly  categorized as "short hedges" and "long
hedges." A short hedge is a purchase or sale of a Derivative Instrument intended
partially  or fully to  offset  potential  declines  in the value of one or more
investments held in the fund's portfolio.  Thus, in a short hedge the fund takes
a position  in a  Derivative  Instrument  whose price is expected to move in the
opposite direction of the price of the investment being hedged. For example, the
fund might  purchase a put option on a  security  to hedge  against a  potential
decline in the value of that  security.  If the price of the  security  declined
below the exercise  price of the put,  the fund could  exercise the put and thus


                                       8
<PAGE>


limit its loss below the  exercise  price to the premium  paid plus  transaction
costs. In the  alternative,  because the value of the put option can be expected
to increase as the value of the underlying security declines,  the fund might be
able to close out the put option and realize a gain to offset the decline in the
value of the security.

      Conversely,  a long hedge is a purchase or sale of a Derivative Instrument
intended  partially or fully to offset  potential  increases in the  acquisition
cost of one or more  investments  that the fund intends to acquire.  Thus,  in a
long hedge, the fund takes a position in a Derivative  Instrument whose price is
expected  to  move  in the  same  direction  as  the  price  of the  prospective
investment being hedged. For example, the fund might purchase a call option on a
security  it intends to  purchase  in order to hedge  against an increase in the
cost of the security.  If the price of the security increased above the exercise
price of the  call,  the fund  could  exercise  the  call  and  thus  limit  its
acquisition  cost to the exercise  price plus the premium  paid and  transaction
costs.  Alternatively,  the fund might be able to offset the price  increase  by
closing out an appreciated call option and realizing a gain.

      Derivative  Instruments on securities  generally are used to hedge against
price  movements in one or more  particular  securities  positions that the fund
owns or  intends  to  acquire.  Derivative  Instruments  on  stock  indices,  in
contrast,  generally are used to hedge  against  price  movements in broad stock
market sectors.

      The use of Derivative  Instruments is subject to applicable regulations of
the SEC, the several  options and futures  exchanges  upon which they are traded
and the Commodity Futures Trading Commission ("CFTC").  In addition,  the fund's
ability to use Derivative Instruments may be limited by tax considerations.  See
"Taxes."

      In addition to the products,  strategies and risks  described below and in
the  Prospectus,  Mitchell  Hutchins may discover  additional  opportunities  in
connection with Derivative Instruments and with hedging, income, return and gain
strategies.   These  new   opportunities  may  become  available  as  regulatory
authorities  broaden the range of permitted  transactions  and as new Derivative
Instruments  and techniques are developed.  Mitchell  Hutchins may utilize these
opportunities  for the fund to the  extent  that  they are  consistent  with the
fund's  investment  objective and permitted by its  investment  limitations  and
applicable  regulatory  authorities.  The  fund's  Prospectus  or  SAI  will  be
supplemented  to the extent that new products or techniques  involve  materially
different risks than those described below or in the Prospectus.

      SPECIAL  RISKS OF  STRATEGIES  USING  DERIVATIVE  INSTRUMENTS.  The use of
Derivative  Instruments involves special  considerations and risks, as described
below.  Risks pertaining to particular  Derivative  Instruments are described in
the sections that follow.

            (1) There might be imperfect  correlation between price movements of
      a Derivative  Instrument and price movements of the  investments  that are
      being hedged. For example, if the value of a Derivative Instrument used in
      a short  hedge  increased  by less than the decline in value of the hedged
      investment,  the  hedge  would  not be  fully  successful.  Such a lack of
      correlation  might  occur  due to  factors  unrelated  to the value of the
      investments  being hedged,  such as speculative or other  pressures on the
      market sin which the Derivative  Instruments are traded. The effectiveness
      of hedges  using  Derivative  Instruments  on indices  will  depend on the
      degree  of  correlation  between  price  movements  in the index and price
      movements in the securities being hedged.

            (2) Hedging  strategies,  if successful,  can reduce risk of loss by
      wholly or partially  offsetting the negative  effect of unfavorable  price
      movements in the investments being hedged. However, hedging strategies can
      also reduce  opportunity  for gain by  offsetting  the positive  effect of
      favorable price movements in the hedged  investments.  For example, if the
      fund  entered into a short hedge  because  Mitchell  Hutchins  projected a
      decline in the price of a security in that fund's portfolio, and the price
      of that security increased  instead,  the gain from that increase might be
      wholly or  partially  offset by a decline  in the price of the  Derivative
      Instrument.  Moreover,  if the price of the Derivative Instrument declined
      by more than the  increase  in the price of the  security,  the fund could
      suffer a loss.  In either such case,  the fund would have been in a better
      position had it not hedged at all.

                                       9

            (3) As  described  below,  the fund might be  required  to  maintain
      assets as "cover,"  maintain  segregated  accounts or make margin payments
      when it takes positions in Derivative Instruments involving obligations to
      third parties (i.e., Derivative Instruments other than purchased options).
      If the fund was  unable  to close  out its  positions  in such  Derivative
      Instruments,  it might be required to continue to maintain  such assets or
      accounts or make such  payments  until the  positions  expired or matured.
      These  requirements  might  impair the fund's  ability to sell a portfolio
      security  or make an  investment  at a time  when it  would  otherwise  be
      favorable to do so, or require that the fund sell a portfolio  security at
      a  disadvantageous  time.  The fund's ability to close out a position in a
      Derivative  Instrument  prior to  expiration  or  maturity  depends on the
      existence  of a liquid  secondary  market  or,  in the  absence  of such a
      market,  the ability and  willingness  of a  counterparty  to enter into a
      transaction  closing out the  position.  Therefore,  there is no assurance
      that any  hedging  position  can be closed out at a time and price that is
      favorable to the fund.

      COVER FOR STRATEGIES  USING  DERIVATIVE  INSTRUMENTS.  Transactions  using
Derivative  Instruments,  other than  purchased  options,  expose the fund to an
obligation to another party. The fund will not enter into any such  transactions
unless it owns either (1) an  offsetting  ("covered")  position  in  securities,
currencies  or  other  options  or  futures  contracts  or (2)  cash  or  liquid
securities  with a  value  sufficient  at  all  times  to  cover  its  potential
obligations  to the extent not covered as  provided in (1) above.  The fund will
comply with SEC guidelines  regarding cover for such  transactions  and will, if
the guidelines so require,  set aside cash or liquid  securities in a segregated
account with its custodian in the prescribed amount.

      Assets used as cover or held in a segregated  account cannot be sold while
the position in the corresponding Derivative Instrument is open, unless they are
replaced  with similar  assets.  As a result,  committing a large portion of the
fund's  assets  to  cover  positions  or to  segregated  accounts  could  impede
portfolio  management or the fund's ability to meet redemption requests or other
current obligations.

      OPTIONS.  The fund may  purchase  put and call  options,  and write (sell)
covered  put or call  options on  securities  in which it invests and indices of
those  securities.  The purchase of call options may serve as a long hedge,  and
the  purchase of put options may serve as a short  hedge.  The fund may also use
options to attempt to enhance  return or realize gains by increasing or reducing
its  exposure  to the  securities  in the S&P 500 Index  without  purchasing  or
selling the  underlying  securities.  Writing  covered  put or call  options can
enable  the  fund to  enhance  income  by  reason  of the  premiums  paid by the
purchasers of such  options.  Writing  covered call options  serves as a limited
short hedge,  because  declines in the value of the hedged  investment  would be
offset to the extent of the premium received for writing the option. However, if
the security  appreciates  to a price higher than the exercise price of the call
option,  it can be expected  that the option will be exercised and the fund will
be obligated to sell the security at less than its market value. Writing covered
put options  serves as a limited long hedge,  because  increases in the value of
the hedged  investment would be offset to the extent of the premium received for
writing the option.  However, if the security  depreciates to a price lower than
the  exercise  price of the put option,  it can be expected  that the put option
will be  exercised  and the fund will be  obligated  to purchase the security at
more than its market  value.  The  securities  or other assets used as cover for
over-the-counter options written by the fund would be considered illiquid to the
extent   described   under   "The   Fund's   Investments,   Related   Risks  and
Limitations--Illiquid Securities."

      The value of an option  position  will reflect,  among other  things,  the
current market value of the  underlying  investment,  the time  remaining  until
expiration,  the  relationship  of the exercise price to the market price of the
underlying  investment,  the  historical  price  volatility  of  the  underlying
investment and general market conditions. Options normally have expiration dates
of  up  to  nine  months.  Generally,  over-the-counter  options  on  bonds  are
European-style  options.  This  means  that the  option  can  only be  exercised
immediately  prior to its  expiration.  This is in  contract  to  American-style
options that may be exercised at any time. There are also other types of options
that may be exercised on certain specified dates before expiration.
Options that expire unexercised have no value.

      The fund may effectively terminate its right or obligation under an option
by entering into a closing transaction.  For example, the fund may terminate its
obligation  under a call or put  option  that it had  written by  purchasing  an
identical call or put option;  this is known as a closing purchase  transaction.
Conversely,  the fund may  terminate  a position  in a put or call option it had
purchased by writing an identical put or call option; this is known as a closing


                                       10
<PAGE>

sale  transaction.  Closing  transactions  permit the fund to realize profits or
limit losses on an option position prior to its exercise or expiration.

      The fund may purchase and write both  exchange-traded and over-the-counter
options.   Currently,   many   options  on  equity   securities   (stocks)   are
exchange-traded.  Exchange markets for options on bonds exist but are relatively
new, and these instruments are primarily traded on the over-the-counter  market.
Exchange-traded   options  in  the  United  States  are  issued  by  a  clearing
organization  affiliated  with the exchange on which the option is listed which,
in effect, guarantees completion of every exchange-traded option transaction. In
contrast,  over-the-counter  options  are  contracts  between  the  fund and its
counterparty   (usually  a  securities  dealer  or  a  bank)  with  no  clearing
organization   guarantee.   Thus,   when  the  fund   purchases   or  writes  an
over-the-counter  option, it relies on the counterparty to make or take delivery
of the  underlying  investment  upon  exercise  of the  option.  Failure  by the
counterparty  to do so would  result in the loss of any premium paid by the fund
as well as the loss of any expected benefit of the transaction.

      The fund's ability to establish and close out positions in exchange-listed
options  depends  on the  existence  of a liquid  market.  The fund  intends  to
purchase or write only those exchange-traded  options for which there appears to
be a liquid  secondary  market.  However,  there can be no assurance that such a
market will exist at any particular time.  Closing  transactions can be made for
over-the-counter options only by negotiating directly with the counterparty,  or
by a transaction in the secondary market if any such market exists. Although the
fund will enter into over-the-counter  options only with counterparties that are
expected  to be capable of entering  into  closing  transactions  with the fund,
there  is no  assurance  that  the  fund  will in fact be able to  close  out an
over-the-counter  option position at a favorable  price prior to expiration.  In
the event of insolvency of the  counterparty,  the fund might be unable to close
out an over-the-counter option position at any time prior to its expiration.

      If the fund were unable to effect a closing  transaction  for an option it
had purchased,  it would have to exercise the option to realize any profit.  The
inability to enter into a closing purchase transaction for a covered put or call
option written by the fund could cause material losses because the fund would be
unable to sell the  investment  used as cover for the written  option  until the
option expires or is exercised.

      LIMITATIONS  ON THE USE OF OPTIONS.  The fund's use of options is governed
by  the  following  guidelines,  which  can be  changed  by  its  board  without
shareholder vote:

      (1) The fund may purchase a put or call option,  including any straddle or
spread,  only if the value of its premium,  when aggregated with the premiums on
all other options held by the fund, does not exceed 5% of its total assets.

      (2) The aggregate  value of securities  underlying put options  written by
the fund, determined as of the date the put options are written, will not exceed
50% of its net assets.

      (3) The  aggregate  premiums  paid on all  options  (including  options on
securities, securities indices and futures contracts) purchased by the fund that
are held at any time will not exceed 20% of its net assets.

      FUTURES. The fund may purchase and sell futures contracts that are related
to  securities  in which it is permitted  to invest,  such as  securities  index
futures contracts. The fund may purchase put and call options, and write covered
put and call options,  on futures in which it is allowed to invest. The purchase
of futures or call  options  thereon can serve as a long hedge,  and the sale of
futures or the  purchase  of put  options  thereon  can serve as a short  hedge.
Writing  covered call options on futures  contracts can serve as a limited short
hedge,  and  writing  covered put  options on futures  contracts  can serve as a
limited long hedge,  using a strategy  similar to that used for writing  covered
options on  securities  or indices.  In addition,  the fund may purchase or sell
futures contracts or purchase options thereon to increase or reduce its exposure
to an asset  class  without  purchasing  or selling the  underlying  securities,
either as a hedge or to enhance return or realize gains.

      No price is paid upon entering into a futures  contract.  Instead,  at the
inception of a futures  contract the fund is required to deposit in a segregated
account with its  custodian,  in the name of the futures broker through whom the


                                       11
<PAGE>


transaction was effected,  "initial margin"  consisting of cash,  obligations of
the United States or obligations  fully  guaranteed as to principal and interest
by the  United  States,  in an  amount  generally  equal  to 10% or  less of the
contract  value.  Margin must also be deposited  when writing a call option on a
futures contract, in accordance with applicable exchange rules. Unlike margin in
securities transactions,  initial margin on futures contracts does not represent
a borrowing,  but rather is in the nature of a  performance  bond or  good-faith
deposit that is returned to the fund at the  termination  of the  transaction if
all contractual  obligations have been satisfied.  Under certain  circumstances,
such as periods of high  volatility,  the fund may be required by an exchange to
increase  the  level  of  its  initial  margin   payment,   and  initial  margin
requirements might be increased generally in the future by regulatory action.

      Subsequent  "variation  margin"  payments are made to and from the futures
broker daily as the value of the futures  position  varies,  a process  known as
"marking to market."  Variation  margin does not involve  borrowing,  but rather
represents a daily  settlement of each fund's  obligations  to or from a futures
broker.  When the fund  purchases  an option on a future,  the premium paid plus
transaction  costs is all that is at risk. In contrast,  when the fund purchases
or sells a futures  contract or writes a call option  thereon,  it is subject to
daily  variation  margin calls that could be substantial in the event of adverse
price  movements.  If the fund has  insufficient  cash to meet  daily  variation
margin requirements,  it might need to sell securities at a time when such sales
are disadvantageous.

      Holders and writers of futures  positions and options on futures can enter
into  offsetting  closing  transactions,  similar  to  closing  transactions  on
options, by selling or purchasing,  respectively, an instrument identical to the
instrument  held or written.  Positions in futures and options on futures may be
closed only on an exchange or board of trade that  provides a secondary  market.
The fund intends to enter into futures  transactions only on exchanges or boards
of trade where there appears to be a liquid secondary market. However, there can
be no  assurance  that such a market will exist for a  particular  contract at a
particular time.

      Under certain circumstances,  futures exchanges may establish daily limits
on the  amount  that the price of a future or  related  option can vary from the
previous day's settlement  price;  once that limit is reached,  no trades may be
made that day at a price  beyond  the  limit.  Daily  price  limits do not limit
potential  losses  because  prices  could  move to the daily  limit for  several
consecutive days with little or no trading,  thereby  preventing  liquidation of
unfavorable positions.

      If the fund were unable to liquidate a futures or related options position
due to the  absence  of a liquid  secondary  market or the  imposition  of price
limits, it could incur substantial losses. The fund would continue to be subject
to market risk with respect to the position. In addition,  except in the case of
purchased  options,  the  fund  would  continue  to be  required  to make  daily
variation  margin  payments and might be required to maintain the position being
hedged by the future or option or to maintain cash or securities in a segregated
account.

      Certain characteristics of the futures market might increase the risk that
movements  in the  prices of futures  contracts  or  related  options  might not
correlate  perfectly  with  movements  in the  prices of the  investments  being
hedged. For example, all participants in the futures and related options markets
are subject to daily variation  margin calls and might be compelled to liquidate
futures or related  options  positions  whose prices are moving  unfavorably  to
avoid being subject to further calls.  These  liquidations  could increase price
volatility of the instruments and distort the normal price relationship  between
the futures or options and the investments being hedged.  Also,  because initial
margin deposit  requirements  in the futures market are less onerous than margin
requirements in the securities markets,  there might be increased  participation
by  speculators  in the futures  markets.  This  participation  also might cause
temporary price  distortions.  In addition,  activities of large traders in both
the futures and securities  markets involving  arbitrage,  "program trading" and
other investment strategies might result in temporary price distortions.

      LIMITATIONS ON THE USE OF FUTURES AND RELATED  OPTIONS.  The fund's use of
futures and related options is governed by the following  guidelines,  which can
be changed by its board without shareholder vote:

      (1) To the extent the fund enters into  futures  contracts  and options on
futures positions that are not for bona fide hedging purposes (as defined by the
CFTC), the aggregate  initial margin and premiums on those positions  (excluding
the amount by which  options  are  "in-the-money")  may not exceed 5% of its net
assets.


                                       12
<PAGE>

      (2) The  aggregate  premiums  paid on all  options  (including  options on
securities, securities indices and futures contracts) purchased by the fund that
are held at any time will not exceed 20% of its net assets.

      (3) The  aggregate  margin  deposits on all futures  contracts and options
thereon held at any time by the fund will not exceed 5% of its total assets.

** Mrs.  Alexander,  Mr. Bewkes,  Ms.  Farrell and  Mr. Storms  are  "interested
   persons"  of the fund as defined in the  Investment  Company Act by virtue of
   their positions with Mitchell Hutchins, PaineWebber, and/or PW Group.


      The Trust pays  trustees  who are not  "interested  persons"  of the Trust
$1,000 for each  series and $150 per  series  for each  board  meeting  and each
separate meeting of a board  committee.  The Trust has only one operating series
and thus pays each such trustee $1,000 annually, plus any additional amounts due
for board or committee meetings.  Each chairman of the audit and contract review
committees  of individual  funds within the  PaineWebber  fund complex  receives
additional  compensation  aggregating  $15,000 annually from the relevant funds.
All trustees are  reimbursed  for any expenses  incurred in attending  meetings.
Trustees and officers own no outstanding shares of the Fund. Because PaineWebber
and Mitchell Hutchins perform  substantially all the services  necessary for the
operation  of the Trust  and the  Fund,  the Trust  requires  no  employees.  No
officer,  director or employee of  Mitchell  Hutchins or  PaineWebber  presently
receives any compensation from the Trust for acting as a trustee or officer.

      INVESTMENT ADVISORY ARRANGEMENTS. Mitchell Hutchins acts as the investment
adviser and  administrator  to the fund  pursuant to a contract  (the  "Advisory

the fund pays Mitchell Hutchins a fee,  computed daily and paid monthly,  at the

August 31, 1999, sorted by category of investment  objective,  of the investment
companies as to which Mitchell  Hutchins  serves as adviser or  sub-adviser.  An
investment company may fall into more than one of the categories below.

      PERSONNEL  TRADING  POLICIES.  Mitchell  Hutchins  personnel may invest in
securities  for their own accounts  pursuant to a code of ethics that  describes
the fiduciary duty owed to shareholders of PaineWebber  funds and other Mitchell
Hutchins advisory  accounts by all Mitchell  Hutchins'  directors,  officers and
employees,  establishes  procedures for personal investing and restricts certain
transactions.  For example,  employee  accounts  generally must be maintained at
PaineWebber,  personal  trades  in most  securities  require  pre-clearance  and
short-term  trading and participation in initial public offerings  generally are
prohibited.  In addition,  the code of ethics puts restrictions on the timing of
personal investing in relation to trades by PaineWebber funds and other Mitchell
Hutchins advisory clients.

      DISTRIBUTION  ARRANGEMENTS.  Mitchell  Hutchins acts as the distributor of
each class of shares of the fund under separate distribution  contracts with the
Trust ("Distribution  Contracts") that require Mitchell Hutchins to use its best
efforts,  consistent  with its  other  businesses,  to sell  shares of the fund.
Shares of the fund are offered  continuously.  Under separate  exclusive  dealer
agreements  between Mitchell Hutchins and PaineWebber  relating to each class of
shares ("Exclusive Dealer Agreements"),  PaineWebber and its correspondent firms
sell the fund's shares.

      Under separate plans of distribution  pertaining to the Class A shares and
Class C shares  adopted by the Trust in the manner  prescribed  under Rule 12b-1
under  the  Investment   Company  Act  ("Class  A  Plan"  and  "Class  C  Plan,"
collectively,  "Plans"),  the fund pays Mitchell Hutchins a service fee, accrued
daily and payable monthly,  at the annual rate of 0.25% of the average daily net
assets of Class A and Class C shares  of the fund.  Under the Class C Plan,  the
fund pays  Mitchell  Hutchins a  distribution  fee,  accrued  daily and  payable
monthly at the annual rate of 0.75% of the average daily net assets of the Class
C shares.  The fund pays Mitchell  Hutchins no distribution fees with respect to
its Class A shares. There is no distribution plan with respect to Class Y shares
and the fund pays no service or  distribution  fees with  respect to its Class Y
shares.

      Mitchell  Hutchins uses the service fees under the Plans for Class A and C
shares primarily to pay PaineWebber for shareholder servicing,  currently at the
annual rate of 0.25% of the aggregate  investment amounts maintained in the fund
by PaineWebber clients.  PaineWebber then compensates its Financial Advisors for
shareholder  servicing  that  they  perform  and  offsets  its own  expenses  in
servicing and maintaining shareholder accounts.

      Mitchell Hutchins uses the distribution fees under the Class C Plan to:

      o     Offset the  commissions  it pays to  PaineWebber  for  selling  each
            fund's Class C shares.

      o     Offset the fund's marketing costs  attributable to such class,  such
            as  preparation,  printing  and  distribution  of sales  literature,
            advertising and  prospectuses  to prospective  investors and related
            overhead expenses, such as employee salaries and bonuses.


                                       21
<PAGE>

      PaineWebber  compensates Financial Advisors when Class C shares are bought
by investors,  as well as on an ongoing  basis.  Mitchell  Hutchins  receives no
special compensation from any of the funds or investors at the time C shares are
bought.

      Mitchell  Hutchins  receives the proceeds of the initial sales charge paid
when Class A shares are bought and of the contingent  deferred sales charge paid
upon sales of shares. These proceeds may be used to cover distribution expenses.

      The Plans and the related  Distribution  Contracts for Class A and Class C
shares specify that the fund must pay service and distribution  fees to Mitchell
Hutchins  for  its  activities,  not  as  reimbursement  for  specific  expenses
incurred.  Therefore,  even if Mitchell Hutchins' expenses exceed the service or
distribution  fees it receives,  the fund will not be obligated to pay more than
those fees. On the other hand, if Mitchell Hutchins' expenses are less than such
fees,  it will retain its full fees and realize a profit.  Expenses in excess of
service and  distribution  fees received or accrued through the termination date
of a Plan will be Mitchell  Hutchins'  sole  responsibility  and not that of the
fund. Annually, the board reviews the Plan and Mitchell Hutchins'  corresponding
expenses  for each  class  separately  from the Plan and  expenses  of the other
class.

      Among other things,  each Plan  provides  that (1) Mitchell  Hutchins will
submit to the board at least  quarterly,  and the trustees will review,  reports
regarding  all amounts  expended  under the Plan and the purposes for which such
expenditures  were made, (2) the Plan will continue in effect only so long as it
is approved at least annually,  and any material  amendment thereto is approved,
by the board,  including those trustees who are not "interested  persons" of the
Trust and who have no direct or indirect  financial interest in the operation of
the Plan or any  agreement  related  to the Plan,  acting in person at a meeting
called for that  purpose,  (3)  payments by the fund under the Plan shall not be
materially  increased  without the affirmative vote of the holders of a majority
of the  outstanding  shares of the relevant class and (4) while the Plan remains
in effect,  the  selection and  nomination  of trustees who are not  "interested
persons" of the Trust shall be committed to the  discretion  of the trustees who
are not "interested persons" of the Trust.

      In  reporting  amounts  expended  under  the Plan to the  board,  Mitchell
Hutchins allocates expenses attributable to the sale of each class of the fund's
shares to such class  based on the ratio of sales of shares of such class to the
sales of all classes of shares.  The fees paid by one class of the fund's shares
will not be used to subsidize the sale of another class of the fund's shares.

      For the fiscal  year ended May 31,  1999,  the fund paid (or  accrued)  to
Mitchell  Hutchins  service fees of  $______________  under the Class A Plan and
service and distribution fees of $_____________________ under the Class C Plan.

      Mitchell   Hutchins   estimates  that  it  and  its  parent   corporation,
PaineWebber,    incurred   the   following   shareholder   service-related   and
distribution-related  expenses  with  respect to the fund during the fiscal year
ended May 31, 1999:

      In approving the fund's overall Flexible PricingSM system of distribution,
the board considered several factors,  including that implementation of Flexible
Pricing would (1) enable  investors to choose the purchasing  option best suited
to their individual situation,  thereby encouraging current shareholders to make
additional  investments  in the fund and  attracting new investors and assets to
the  fund to the  benefit  of the  fund  and its  shareholders,  (2)  facilitate
distribution of the fund's shares and (3) maintain the  competitive  position of
the fund in  relation  to other  funds that have  implemented  or are seeking to
implement similar distribution arrangements.

      In approving the Class A Plan,  the board  considered  all the features of
the distribution system,  including (1) the conditions under which initial sales
charges would be imposed and the amount of such charges,  (2) Mitchell Hutchins'
belief  that the  initial  sales  charge  combined  with a service  fee would be
attractive to PaineWebber Financial Advisors and correspondent firms,  resulting
in  greater  growth  of the fund  than  might  otherwise  be the  case,  (3) the
advantages to the  shareholders  of economies of scale  resulting from growth in
the fund's assets and potential  continued growth,  (4) the services provided to
the fund and its shareholders by Mitchell Hutchins, (5) the services provided by
PaineWebber  pursuant to its Exclusive Dealer  Agreement with Mitchell  Hutchins
and (6) Mitchell Hutchins' shareholder service-related expenses and costs.

      In approving the Class C Plan,  the board  considered  all the features of
the distribution  system,  including (1) the advantage to investors in having no
initial  sales  charges  deducted  from the fund  purchase  payments and instead
having the entire amount of their purchase payments immediately invested in fund
shares,  (2) the advantage to investors in being free from  contingent  deferred
sales charges upon  redemption for shares held more than one year and paying for
distribution on an ongoing basis, (3) Mitchell Hutchins' belief that the ability
of  PaineWebber  Financial  Advisors and  correspondent  firms to receive  sales
compensation  for their sales of Class C shares on an ongoing basis,  along with
continuing  service fees,  while their  customers  invest their entire  purchase
payments  immediately  in Class C shares and  generally  do not face  contingent
deferred sales  charges,  would prove  attractive to the Financial  Advisors and
correspondent  firms,  resulting  in  greater  growth  to the  fund  than  might
otherwise be the case,  (4) the  advantage to the  shareholders  of economies of
scale resulting from growth in the fund's assets and potential continued growth,
(5) the services provided to the fund and its shareholders by Mitchell Hutchins,


                                       23
<PAGE>

(6) the  services  provided  by  PaineWebber  pursuant to its  Exclusive  Dealer
Agreement with Mitchell Hutchins and (7) Mitchell Hutchins' shareholder service-
and  distribution-related  expenses and costs. The board members also recognized
that Mitchell Hutchins' willingness to compensate  PaineWebber and its Financial
Advisors without the concomitant  receipt by Mitchell  Hutchins of initial sales
charges or contingent  deferred sales charges upon  redemption,  was conditioned
upon its expectation of being compensated under the Class C Plan.

      With respect to each Plan,  the board  considered  all  compensation  that
Mitchell  Hutchins would receive under the Plan and the  Distribution  Contract,
including  service and, as  applicable,  initial  sales charge and  distribution
fees.  The board also  considered  the  benefits  that would  accrue to Mitchell
Hutchins  under the Plan in that Mitchell  Hutchins  would  receive  service and
advisory  fees which are  calculated  based upon a percentage of the average net
assets of the fund,  which would  increase if the Plan were  successful  and the
fund attained and maintained significant asset levels.

      Under the Distribution Contract between the fund and Mitchell Hutchins for
the Class A shares for the periods set forth below, Mitchell Hutchins earned the
following  approximate  amounts of sales  charges  and  retained  the  following
approximate amounts, net of concessions to PaineWebber as exclusive dealer.

                             PORTFOLIO TRANSACTIONS

      Subject  to  policies  established  by the  board,  Mitchell  Hutchins  is
responsible  for the  execution  of the fund's  portfolio  transactions  and the
allocation  of  brokerage  transactions.  In executing  portfolio  transactions,
Mitchell  Hutchins  generally seeks to obtain the best net results for the fund,
taking  into  account  such  factors  as the  price  (including  the  applicable
brokerage commission or dealer spread),  size of order,  difficulty of execution
and  operational  facilities  of the  firm  involved.  While  Mitchell  Hutchins
generally seeks reasonably  competitive  commission rates, payment of the lowest
commission is not  necessarily  consistent  with obtaining the best net results.
Prices  paid to dealers in  principal  transactions,  through  which some equity
securities and most debt  securities are traded,  generally  include a "spread,"
which is the  difference  between  the  prices at which the dealer is willing to
purchase  and sell a  specific  security  at the  time.  The fund may  invest in
securities  traded in the  over-the-counter  market and will engage primarily in
transactions  directly  with the  dealers who make  markets in such  securities,
unless a better price or execution could be obtained by using a broker.  For the
fiscal year ended May 31, 1999 and the period December 31, 1997 (commencement of
operations)  to May 31,  1998,  the fund  paid  $________  and  $___________  in
brokerage commissions, respectively.

      The fund has no  obligation to deal with any broker or group of brokers in
the execution of portfolio transactions.  The fund contemplates that, consistent
with the policy of obtaining the best net results, brokerage transactions may be
conducted through  PaineWebber.  The board has adopted  procedures in conformity
with Rule 17e-1 under the  Investment  Company Act to ensure that all  brokerage


                                       24
<PAGE>

commissions paid to PaineWebber are reasonable and fair.  Specific provisions in
the Advisory Contract authorize PaineWebber to effect portfolio transactions for
the fund on a national securities exchange of which it is a member and to retain
compensation in connection with such transactions. Any such transactions will be
effected and related  compensation  paid only in accordance  with applicable SEC
regulations.  For the fiscal year ended May 31, 1999 and the period December 31,
1997  (commencement of operations) to May 31, 1998, the fund [paid no] brokerage
commissions to PaineWebber or any other affiliate of Mitchell Hutchins.

      Transactions in futures contracts are executed through futures  commission
merchants ("FCMs"),  who receive brokerage  commissions for their services.  The
fund's  procedures  in  selecting  FCMs to execute its  transactions  in futures
contracts,  including procedures permitting the use of PaineWebber,  are similar
to those in effect with respect to brokerage transactions in securities.

      Consistent with the interests of the fund and subject to the review of the
board,  Mitchell  Hutchins  may cause the fund to  purchase  and sell  portfolio
securities from and to dealers or through brokers who provide Mitchell  Hutchins
with research,  analysis, advice and similar services. The fund may pay to those
brokers a higher commission than may be charged by other brokers,  provided that
Mitchell Hutchins determines in good faith that such commission is reasonable in
terms either of that particular  transaction or of the overall responsibility of
Mitchell  Hutchins  to the  fund  and its  other  clients  and  that  the  total
commissions  paid by the fund will be  reasonable in relation to the benefits to
the fund over the long term.  [During  the fiscal year ended May 31,  1999,  the
fund directed no brokerage  transactions to brokers chosen because they provided
research services. ]

      For  purchases or sales with  broker-dealer  firms which act as principal,
Mitchell  Hutchins seeks best execution.  Although Mitchell Hutchins may receive
certain research or execution services in connection with these transactions, it
will not purchase  securities  at a higher price or sell  securities  at a lower
price than would  otherwise be paid if no weight was  attributed to the services
provided  by the  executing  dealer.  Mitchell  Hutchins  may  engage  in agency
transactions in  over-the-counter  equity  securities in return for research and
execution services.  These transactions are entered into only in compliance with
procedures ensuring that the transaction (including  commissions) is at least as
favorable as it would have been if effected  directly with a  market-maker  that
did not  provide  research  or  execution  services.  These  procedures  include
Mitchell  Hutchins  receiving  multiple quotes from dealers before executing the
transactions on an agency basis.

      Information and research services  furnished by brokers or dealers through
which or with  which the fund  effects  securities  transactions  may be used by
Mitchell Hutchins in advising other funds or accounts and, conversely,  research
services furnished to Mitchell Hutchins by brokers or dealers in connection with
other  funds or  accounts  that it  advises  may be used in  advising  the fund.
Information  and research  received  from brokers or dealers will be in addition
to,  and not in lieu of, the  services  required  to be  performed  by  Mitchell
Hutchins under the Advisory Contract.

      Investment  decisions  for the  fund  and for  other  investment  accounts
managed by Mitchell  Hutchins are made  independently  of each other in light of
differing considerations for the various accounts.  However, the same investment
decision may occasionally be made for the fund and one or more of such accounts.
In such cases, simultaneous transactions are inevitable.  Purchases or sales are
then  averaged  as to price  and  allocated  between  the  fund  and such  other
account(s) as to amount  according to a formula deemed equitable to the fund and
such  account(s).  While in some cases this  practice  could have a  detrimental
effect upon the price or value of the security as far as the fund is  concerned,
or upon its ability to complete its entire order,  in other cases it is believed
that coordination and the ability to participate in volume  transactions will be
beneficial to the fund.

      The fund will not purchase securities that are offered in underwritings in
which  PaineWebber  is a member of the  underwriting  or selling  group,  except
pursuant  to  procedures  adopted by the board  pursuant to Rule 10f-3 under the
Investment  Company Act. Among other things,  these procedures  require that the
spread or commission  paid in connection  with such a purchase be reasonable and
fair,  the purchase be at not more than the public  offering  price prior to the
end of the first  business  day after the date of the public  offering  and that
PaineWebber or any affiliate thereof not participate in or benefit from the sale
to the fund.

      PORTFOLIO  TURNOVER.  The fund's annual  portfolio  turnover rate may vary
greatly  from year to year,  but will not be a limiting  factor when  management
deems portfolio changes  appropriate.  The portfolio turnover rate is calculated
by dividing  the lesser of the fund's  annual  sales or  purchases  of portfolio
securities  (exclusive of purchases or sales of securities  whose  maturities at
the time of acquisition  were one year or less) by the monthly  average value of
securities in the portfolio  during the year.  For the fiscal year ended May 31,
1999 and the period  December 31, 1997  (commencement  of operations) to May 31,
1998, the fund's portfolio turnover rate was ____ % and 1%, respectively.

          REDUCED SALES CHARGES, ADDITIONAL EXCHANGE AND REDEMPTION
                         INFORMATION AND OTHER SERVICES

      WAIVERS  OF SALES  CHARGES/CONTINGENT  DEFERRED  SALES  CHARGES -- CLASS A
SHARES. The following  additional sales charge waivers are available for Class A
shares if you:

      o     Purchase shares through a variable annuity offered only to qualified
            plans.  For  investments  made  pursuant  to this  waiver,  Mitchell
            Hutchins may make payments out of its own  resources to  PaineWebber
            and to the variable annuity's  sponsor,  adviser or distributor in a
            total amount not to exceed l% of the amount invested;

      o     Acquire shares  through an investment  program that is not sponsored
            by PaineWebber or its affiliates and that charges participants a fee
            for program services,  provided that the program sponsor has entered
            into a written  agreement  with  PaineWebber  permitting the sale of
            shares at net asset  value to that  program.  For  investments  made
            pursuant to this  waiver,  Mitchell  Hutchins  may make a payment to
            PaineWebber  out of its own  resources in an amount not to exceed 1%
            of the amount invested. For subsequent investments or exchanges made
            to implement a rebalancing  feature of such an  investment  program,
            the minimum subsequent investment requirement is also waived;

      o     Acquire shares in connection with a reorganization pursuant to which
            the fund acquires substantially all of the assets and liabilities of
            another fund in exchange solely for shares of the acquiring fund; or

      o     Acquire shares in connection  with the  disposition of proceeds from
            the sale of shares of Managed  High  Yield Plus Fund Inc.  that were
            acquired  during the fund's  initial  public  offering of shares and
            that meet certain other conditions described in its prospectus

      In addition, reduced sales charges on Class A shares are available through
the combined  purchase plan or through rights of accumulation  described  below.
Class A share  purchases  of $1  million  or more are not  subject to an initial
sales charge; however, if a shareholder sells these shares within one year after
purchase,  a contingent deferred sales charge of 1% of the offering price or the
net asset value of the shares at the time of sale by the shareholder,  whichever
is less, is imposed.

      COMBINED PURCHASE  PRIVILEGE-CLASS A SHARES. Investors and eligible groups
of related fund  investors  may combine  purchases of Class A shares of the fund
with concurrent purchases of Class A shares of any other PaineWebber mutual fund
and thus take  advantage of the reduced sales charges  indicated in the table of
sales charges for Class A shares in the Prospectus.  The sales charge payable on
the  purchase  of Class A shares of the fund and  Class A shares  of such  other
funds  will be at the  rates  applicable  to the total  amount  of the  combined
concurrent purchases.

      An  "eligible  group  of  related  fund  investors"  can  consist  of  any
combination of the following:

      (a)  an individual, that individual's spouse, parents and children;

      (b)  an  individual  and   his  or   her  Individual   Retirement  Account
("IRA");


                                       26
<PAGE>

      (c) an  individual  (or  eligible  group of  individuals)  and any company
controlled  by the  individual(s)  (a person,  entity or group that holds 25% or
more of the  outstanding  voting  securities of a corporation  will be deemed to
control the  corporation,  and a partnership  will be deemed to be controlled by
each of its general partners);

      (d) an  individual  (or  eligible  group of  individuals)  and one or more
employee benefit plans of a company controlled by individual(s);

      (e) an individual (or eligible group of  individuals)  and a trust created
by the  individual(s),  the beneficiaries of which are the individual and/or the
individual's spouse, parents or children;

      (f) an individual and a Uniform Gifts to Minors  Act/Uniform  Transfers to
Minors Act account created by the individual or the individual's spouse;

      (g) an employer (or group of related  employers) and one or more qualified
retirement  plans  of such  employer  or  employers  (an  employer  controlling,
controlled by or under common control with another employer is deemed related to
that other employer); or

      (h) individual  accounts related together under one registered  investment
adviser  having full  discretion  and control over the accounts.  The registered
investment  adviser must communicate at least quarterly  through a newsletter or
investment update establishing a relationship with all of the accounts.

      RIGHTS OF ACCUMULATION-CLASS A SHARES. Reduced sales charges are available
through a right of  accumulation,  under which  investors and eligible groups of
related fund  investors  (as defined  above) are  permitted to purchase  Class A
shares of the fund among related  accounts at the offering  price  applicable to
the total of (1) the dollar amount then being purchased plus (2) an amount equal
to the  then-current  net asset value of the  purchaser's  combined  holdings of
Class A fund shares and Class A shares of any other PaineWebber mutual fund. The
purchaser must provide sufficient  information to permit  confirmation of his or
her  holdings,  and the  acceptance  of the  purchase  order is  subject to such
confirmation.  The right of  accumulation  may be amended or  terminated  at any
time.

      REINSTATEMENT PRIVILEGE -- CLASS A SHARES.  Shareholders who have redeemed
Class A shares of the fund may reinstate their account without a sales charge by
notifying  the  transfer  agent of such  desire and  forwarding  a check for the
amount  to be  purchased  within  365 days  after  the date of  redemption.  The
reinstatement  will be made at the net asset value per share next computed after
the notice of  reinstatement  and check are  received.  The amount of a purchase
under this  reinstatement  privilege  cannot exceed the amount of the redemption
proceeds.   Gain  on  a  redemption   is  taxable   regardless  of  whether  the
reinstatement  privilege  is  exercised,  although  a  loss  arising  out  of  a
redemption  might not be  deductible  under certain  circumstances.  See "Taxes"
below.

      PURCHASES OF CLASS Y SHARES  THROUGH THE PACE MULTI  ADVISOR  PROGRAM.  An
investor  who  participates  in the PACE Multi  Advisor  Program is  eligible to
purchase Class Y shares.  The PACE Multi Advisor Program is an advisory  program
sponsored  by  PaineWebber  that  provides  comprehensive  investment  services,
including investor profiling,  a personalized asset allocation strategy using an
appropriate combination of funds, and a quarterly investment performance review.
Participation  in the PACE  Multi  Advisor  Program  is subject to payment of an
advisory fee at the effective  maximum annual rate of 1.5% of assets.  Employees
of PaineWebber  and its affiliates are entitled to a waiver of this fee.  Please
contact your PaineWebber Financial Advisor or PaineWebber's  correspondent firms
for more information concerning mutual funds that are available through the PACE
Multi Advisor Program.

      ADDITIONAL  EXCHANGE  AND  REDEMPTION  INFORMATION.  As  discussed  in the
Prospectus,  eligible  shares  of the fund may be  exchanged  for  shares of the
corresponding  class of most other PaineWebber  mutual funds. Class Y shares are
not eligible for exchange. Shareholders will receive at least 60 days' notice of
any termination or material modification of the exchange offer, except no notice
need be given if, under  extraordinary  circumstances,  either  redemptions  are
suspended under the circumstances described below or the fund temporarily delays


                                       27
<PAGE>

or  ceases  the sales of its  shares  because  it is  unable  to invest  amounts
effectively in accordance  with the fund's  investment  objective,  policies and
restrictions.

      If conditions exist that make cash payments undesirable, the fund reserves
the right to honor any request for  redemption by making  payment in whole or in
part in  securities  chosen by the fund and valued in the same way as they would
be valued  for  purposes  of  computing  the fund's  net asset  value.  Any such
redemption  in kind  will be made with  readily  marketable  securities,  to the
extent  available.  If payment is made in  securities,  a shareholder  may incur
brokerage expenses in converting these securities into cash.

      The fund may suspend redemption privileges or postpone the date of payment
during any period (1) when the New York Stock  Exchange  is closed or trading on
the New York Stock  Exchange is restricted as determined by the SEC, (2) when an
emergency  exists,  as  defined  by  the  SEC,  that  makes  it  not  reasonably
practicable  for the fund to  dispose  of  securities  owned by it or  fairly to
determine  the value of its assets or (3) as the SEC may otherwise  permit.  The
redemption price may be more or less than the shareholder's  cost,  depending on
the market value of the fund's portfolio at the time.

      SERVICE ORGANIZATIONS.  The fund may authorize service organizations,  and
their agents, to accept on its behalf purchase and redemption orders that are in
"good  form."  The fund will be  deemed  to have  received  these  purchase  and
redemption  orders when a service  organization  or its agent accepts them. Like
all customer  orders,  these orders will be priced based on the fund's net asset
value next computed after receipt of the order by the service  organizations  or
their  agents.   Service  organizations  may  include  retirement  plan  service
providers  who  aggregate  purchase and  redemption  instructions  received from
numerous retirement plans or plan participants.

      AUTOMATIC INVESTMENT PLAN.  Participation in the Automatic Investment Plan
enables an investor to use the  technique  of "dollar cost  averaging."  When an
investor  invests the same dollar amount each month under the Plan, the investor
will  purchase  more shares when the fund's net asset value per share is low and
fewer shares when the net asset value per share is high.  Using this  technique,
an  investor's  average  purchase  price per share over any given period will be
lower than if the investor purchased a fixed number of shares on a monthly basis
during the period. Of course,  investing  through the automatic  investment plan
does  not  assure  a  profit  or  protect  against  loss in  declining  markets.
Additionally,   because  the  automatic   investment  plan  involves  continuous
investing  regardless of price levels,  an investor  should  consider his or her
financial ability to continue purchases through periods of low price levels.

      SYSTEMATIC   WITHDRAWAL  PLAN.  The  systematic   withdrawal  plan  allows
investors to set up monthly,  quarterly (March,  June,  September and December),
semi-annual  (June and  December) or annual  (December)  withdrawals  from their
PaineWebber  Mutual  Fund  accounts.   Minimum  balances  and  withdrawals  vary
according to the class of shares:

      o     Class A and Class C shares.  Minimum value of fund shares is $5,000;
            minimum withdrawals of $100.

      Withdrawals under the systematic  withdrawal plan will not be subject to a
contingent  deferred sales charge if the investor  withdraws no more than 12% of
the value of the fund account  when the  investor  signed up for the Plan during
the first year under the Plan.  Shareholders  who elect to receive  dividends or
other distributions in cash may not participate in this plan.

      An  investor's  participation  in  the  systematic  withdrawal  plan  will
terminate  automatically if the "Initial Account Balance" (a term that means the
value of the fund account at the time the investor  elects to participate in the
systematic  withdrawal plan) less aggregate redemptions made other than pursuant
to the  systematic  withdrawal  plan is less than $5,000 for Class A and Class C
shareholders.  Purchases  of  additional  shares  of the  fund  concurrent  with
withdrawals  are  ordinarily  disadvantageous  to  shareholders  because  of tax
liabilities.  On or  about  the  20th  of each  month  for  monthly,  quarterly,
semiannual or annual plans,  PaineWebber will arrange for redemption by the fund
of  sufficient  fund  shares to provide the  withdrawal  payments  specified  by
participants in the fund's  systematic  withdrawal plan. The payments  generally
are mailed  approximately  five  Business  Days  (defined  under  "Valuation  of


                                       28
<PAGE>

Shares") after the redemption date. Withdrawal payments should not be considered
dividends,  but redemption proceeds,  with the tax consequences  described under
"Dividends  & Taxes" in the  Prospectus.  If  periodic  withdrawals  continually
exceed reinvested dividends and other distributions,  a shareholder's investment
may be  correspondingly  reduced.  A  shareholder  may  change the amount of the
systematic  withdrawal or terminate  participation in the systematic  withdrawal
plan at any  time  without  charge  or  penalty  by  written  instructions  with
signatures  guaranteed to PaineWebber or PFPC Inc..  Instructions to participate
in the plan, change the withdrawal amount or terminate participation in the plan
will not be effective until five days after written instructions with signatures
guaranteed  are received by PFPC.  Shareholders  may request the forms needed to
establish  a  systematic   withdrawal  plan  from  their  PaineWebber  Financial
Advisors, correspondent firms or PFPC at 1-800-647-1568.

      INDIVIDUAL  RETIREMENT ACCOUNTS.  Self-directed IRAs are available through
PaineWebber in which purchases of PaineWebber mutual funds and other investments
may be made. Investors considering  establishing an IRA should review applicable
tax laws and should consult their tax advisers.

      TRANSFER  OF  ACCOUNTS.  If  investors  holding  shares  of the  fund in a
PaineWebber brokerage account transfer their brokerage accounts to another firm,
the fund shares  will be moved to an account  with PFPC.  However,  if the other
firm has  entered  into a  selected  dealer  agreement  with  Mitchell  Hutchins
relating  to the fund,  the  shareholder  may be able to hold fund  shares in an
account with the other firm.

PAINEWEBBER RMA RESOURCE ACCUMULATION PLANSM
PAINEWEBBER RESOURCE MANAGEMENT ACCOUNT(REGISTERE) (RMA)(REGISTERED)

      Shares of PaineWebber  mutual funds,  including the fund (each a "PW Fund"
and,  collectively,  the "PW funds") are available for purchase  through the RMA
Resource  Accumulation  Plan  ("Plan")  by  customers  of  PaineWebber  and  its
correspondent   firms  who   maintain   Resource   Management   Accounts   ("RMA
accountholders").  The Plan allows an RMA accountholder continually to invest in
one or more of the PW  Funds at  regular  intervals,  with  payment  for  shares
purchased  automatically  deducted from the client's RMA account. The client may
elect to invest at monthly or quarterly intervals and may elect either to invest
a fixed dollar amount (minimum $100 per period) or to purchase a fixed number of
shares.  A client  can elect to have  Plan  purchases  executed  on the first or
fifteenth day of the month. Settlement occurs three Business Days (defined under
"Valuation  of Shares")  after the trade  date,  and the  purchase  price of the
shares is withdrawn from the investor's RMA account on the settlement  date from
the following  sources and in the following  order:  uninvested  cash  balances,
balances in RMA money market funds, or margin  borrowing power, if applicable to
the account.

      To participate in the Plan, an investor must be an RMA accountholder, must
have  made an  initial  purchase  of the  shares  of each PW Fund  selected  for
investment under the Plan (meeting  applicable minimum investment  requirements)
and must complete and submit the RMA Resource Accumulation Plan Client Agreement
and Instruction Form available from PaineWebber. The investor must have received
a current  prospectus  for each PW Fund selected prior to enrolling in the Plan.
Information about mutual fund positions and outstanding  instructions  under the
Plan are noted on the RMA accountholder's account statement.  Instructions under
the Plan may be  changed  at any  time,  but may take up to two  weeks to become
effective.

      The  terms of the Plan,  or an RMA  accountholder's  participation  in the
Plan, may be modified or terminated at any time. It is anticipated  that, in the
future, shares of other PW Funds and/or mutual funds other than the PW Funds may
be offered through the Plan.

      PERIODIC INVESTING AND DOLLAR COST AVERAGING. Periodic investing in the PW
Funds or other  mutual  funds,  whether  through  the Plan or  otherwise,  helps
investors  establish and maintain a disciplined  approach to accumulating assets
over time,  deemphasizing  the importance of timing the market's highs and lows.
Periodic  investing  also permits an investor to take  advantage of "dollar cost
averaging."  By  investing a fixed  amount in mutual fund shares at  established
intervals,  an investor  purchases more shares when the price is lower and fewer
shares  when  the  price  is  higher,  thereby  increasing  his or  her  earning
potential.  Of course,  dollar  cost  averaging  does not  guarantee a profit or
protect  against a loss in a declining  market,  and an investor should consider
his or her financial ability to continue  investing through periods of low share


                                       29
<PAGE>

prices.  However,  over time, dollar cost averaging generally results in a lower
average  original  investment cost than if an investor  invested a larger dollar
amount in a mutual fund at one time.

      PAINEWEBBER'S RESOURCE MANAGEMENT ACCOUNT. In order to enroll in the Plan,
an  investor  must have  opened an RMA account  with  PaineWebber  or one of its
correspondent  firms.  The RMA  account  is  PaineWebber's  comprehensive  asset
management  account and offers  investors a number of  features,  including  the
following:

      o     monthly  Premier   account   statements  that  itemize  all  account
            activity,  including investment transactions,  checking activity and
            Gold  MasterCard(REGISTERED)  transactions  during the  period,  and
            provide  unrealized  and realized  gain and loss  estimates for most
            securities held in the account;

      o     comprehensive  year-end summary statements that provide  information
            on  account  activity  for  use  in  tax  planning  and  tax  return
            preparation;

      o     automatic  "sweep" of uninvested  cash into the RMA  accountholder's
            choice of one of the six RMA money  market  funds-- RMA Money Market
            Portfolio,  RMA U.S.  Government  Portfolio,  RMA Tax-Free Fund, RMA
            California Municipal Money Fund, RMA New Jersey Municipal Money Fund
            and RMA New York  Municipal  Money Fund.  AN  INVESTMENT  IN A MONEY
            MARKET FUND IS NOT  INSURED OR  GUARANTEED  BY THE  FEDERAL  DEPOSIT
            INSURANCE  CORPORATION OR ANY OTHER  GOVERNMENT  AGENCY.  ALTHOUGH A
            MONEY MARKET FUND SEEKS TO PRESERVE THE VALUE OF YOUR  INVESTMENT AT
            $1.00 PER SHARE,  IT IS  POSSIBLE  TO LOSE MONEY BY  INVESTING  IN A
            MONEY MARKET FUND.

      o     check writing,  with no per-check usage charge, no minimum amount on
            checks  and no maximum  number of checks  that can be  written.  RMA
            accountholders can code their checks to classify  expenditures.  All
            canceled checks are returned each month;

      o     Gold  MasterCard,  with or without a line of credit,  which provides
            RMA  accountholders  with direct access to their accounts and can be
            used with automatic teller machines worldwide. Purchases on the Gold
            MasterCard  are debited to the RMA account once monthly,  permitting
            accountholders to remain invested for a longer period of time;

      o     unlimited electronic funds transfers and bill payment service for an
            additional fee;

      o     24-hour access to account information through toll-free numbers, and
            more detailed personal assistance during business hours from the RMA
            Service Center;

      o     expanded account  protection to the net equity securities balance in
            the event of the  liquidation of  PaineWebber.  This protection does
            not apply to shares of the PW Funds that are held  directly  at PFPC
            and not through PaineWebber; and

      o     automatic  direct  deposit  of  checks  into  your RMA  account  and

      The annual  account fee for an RMA account is $85, which includes the Gold

                               VALUATION OF SHARES

      The fund  determines  its net asset  value per share  separately  for each
class of shares normally as of the close of regular trading  (usually 4:00 p.m.,
Eastern  time) on the New York Stock  Exchange on each  Business  Day,  which is
defined as each Monday  through Friday when the New York Stock Exchange is open.
Prices will be calculated earlier when the NYSE closes early because trading has
been halted for the day.  Currently the New York Stock Exchange is closed on the
observance of the following  holidays:  New Year's Day,  Martin Luther King, Jr.


                                       30
<PAGE>

Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence Day, Labor Day,
Thanksgiving Day and Christmas Day.

      Securities  that are listed on  exchanges  normally are valued at the last
sale price on the day the  securities  are valued or,  lacking any sales on such
day, at the last  available bid price.  In cases where  securities are traded on
more than one exchange,  the  securities  are  generally  valued on the exchange
considered by Mitchell Hutchins as the primary market.  Securities traded in the
over-the-counter  market  and  listed  on the  Nasdaq  Stock  Market  ("Nasdaq")
normally  are  valued  at the  last  available  sale  price on  Nasdaq  prior to
valuation;  other  over-the-counter  securities are valued at the last bid price
available  prior to valuation.  Where market  quotations are readily  available,
portfolio  securities  are valued based upon market  quotations,  provided those
quotations  adequately reflect,  in the judgment of Mitchell Hutchins,  the fair
value of the security.  Where those market quotations are not readily available,
securities  are valued based upon  appraisals  received  from a pricing  service
using a  computerized  matrix  system  or based  upon  appraisals  derived  from
information   concerning  the  security  or  similar  securities  received  from
recognized  dealers in those  securities.  All other securities and other assets
are valued at fair value as  determined  in good faith by or under the direction
of the board. The amortized cost method of valuation  generally is used to value
debt obligations with 60 days or less remaining until maturity, unless the board
determines that this does not represent fair value.

                             PERFORMANCE INFORMATION

      The fund's  performance  data quoted in advertising and other  promotional
materials ("Performance  Advertisements") represents past performance and is not
intended to indicate  future  performance.  The investment  return and principal
value  of an  investment  will  fluctuate  so that an  investor's  shares,  when
redeemed, may be worth more or less than their original cost.

      TOTAL  RETURN   CALCULATIONS.   Average   annual  total  return   quotes
("Standardized  Return") used in the fund's  Performance  Advertisements are
calculated according to the following formula:

               n
       P(1 + T)   =  ERV
     where:  P    =  a hypothetical initial payment of $1,000 to purchase shares
                     of a specified class
             T    =  average  annual total return of shares of that class
             n    =  number of years
           ERV    =  ending redeemable value of a hypothetical $1,000 payment at
                     the beginning of that period.

      Under  the  foregoing  formula,  the  time  periods  used  in  Performance
Advertisements  will be based on rolling calendar quarters,  updated to the last
day of the most recent  quarter  prior to submission  of the  advertisement  for
publication.  Total return,  or "T" in the formula above, is computed by finding
the average annual change in the value of an initial $1,000  investment over the
period.  In calculating the ending  redeemable  value,  for Class A shares,  the
maximum 2.5% sales charge is deducted from the initial  $1,000  payment and, for
Class C shares,  the  applicable  contingent  deferred sales charge imposed on a
redemption of Class C shares held for the period is deducted.  All dividends and
other distributions are assumed to have been reinvested at net asset value.

      The fund  also may refer in  Performance  Advertisements  to total  return
performance  data that are not  calculated  according  to the  formula set forth
above ("Non-Standardized  Return"). The fund calculates  Non-Standardized Return
for specified periods of time by assuming an investment of $1,000 in fund shares
and assuming the reinvestment of all dividends and other distributions. The rate
of return is determined by subtracting  the initial value of the investment from
the ending value and by dividing the  remainder  by the initial  value.  Neither
initial  nor  contingent  deferred  sales  charges  are taken  into  account  in
calculating Non-Standardized Return; the inclusion of those charges would reduce
the return.

      OTHER INFORMATION. In Performance Advertisements, the fund may compare its
Standardized  Return with data  published by Lipper  Analytical  Services,  Inc.
("Lipper"), CDA Investment Technologies,  Inc. ("CDA"),  Wiesenberger Investment
Companies  Service  ("Wiesenberger"),  Investment  Company Data, Inc. ("ICD") or
Morningstar  Mutual funds  ("Morningstar"),  with the  performance of recognized
stock and other indices,  including (but not limited to) the S&P 500 Index,  the
Dow Jones Industrial Average, the International Finance Corporation Global Total
Return Index,  the Nasdaq  Composite Index, the Russell 2000 Index, the Wilshire

Bond Index, the Salomon Brothers World Government  Index,  other similar Salomon
Brothers  indices or components  thereof and changes in the Consumer Price Index
as published by the U.S. Department of Commerce. The fund also may refer in such
materials  to  mutual  fund  performance   rankings  and  other  data,  such  as
comparative  asset,   expense  and  fee  levels,   published  by  Lipper,   CDA,
Wiesenberger,  ICD or Morningstar.  Performance Advertisements also may refer to
discussions of the fund and comparative mutual fund data and ratings reported in
independent periodicals, including (but not limited to) THE WALL STREET JOURNAL,
MONEY MAGAZINE,  FORBES, BUSINESS WEEK, FINANCIAL WORLD, BARRON'S,  FORTUNE, THE
NEW YORK TIMES,  THE CHICAGO  TRIBUNE,  THE  WASHINGTON  POST AND THE  KIPLINGER
LETTERS. Comparisons in Performance Advertisements may be in graphic form.

      The fund may  include  discussions  or  illustrations  of the  effects  of
compounding  in  Performance  Advertisements.  "Compounding"  refers to the fact
that, if dividends or other  distributions on the fund investment are reinvested
in additional fund shares, any future income or capital appreciation of the fund
would increase the value, not only of the original fund investment,  but also of
the additional fund shares received through reinvestment. As a result, the value
of the fund  investment  would  increase more quickly than if dividends or other
distributions  had been paid in cash.  The fund may also  generally  discuss  or
illustrate the increasingly popular benefits of investing through an index fund,
such as  immediate  diversification;  convenience;  relatively  lower  portfolio
turnover and expected transaction costs; and the likelihood that lower portfolio
turnover will result in otherwise higher after-tax returns.

      The fund may also compare its  performance  with the  performance  of bank
certificates  of deposit  (CDs) as  measured by the CDA  Certificate  of Deposit
Index, the Bank Rate Monitor National Index and the averages of yields of CDs of
major banks published by  Banxquote(REGISTERED)  Money Markets. In comparing the
fund's  performance to CD performance,  investors  should keep in mind that bank
CDs are  insured  in whole or in part by an  agency of the U.S.  government  and
offer fixed principal and fixed or variable rates of interest,  and that bank CD
yields may


                                       32
<PAGE>

vary  depending on the  financial  institution  offering  the CD and  prevailing
interest  rates.  Shares of the fund are not insured or  guaranteed  by the U.S.
government and returns and net asset values will fluctuate.  The debt securities
held by the  fund may  have  longer  maturities  than  most CDs and may  reflect
interest rate fluctuations for longer term debt securities. An investment in the
fund involves  greater risks than an investment in either a money market fund or
a CD.

      The fund may also compare its  performance  to general trends in the stock
and bond markets,  as  illustrated  by the following  graph prepared by Ibbotson
Associates, Chicago.*

                                     [CHART]

                                [TO BE INSERTED]

      * Source:  Stocks,  Bonds,  Bills and Inflation 1998  YearbookTM  Ibbotson
Assoc., Chi., (annual updates work by Roger G. Ibbotson & Rex A. Sinquefield).

      The chart is shown for  illustrative  purposes only and does not represent
the fund's performance. These returns consist of income and capital appreciation
(or  depreciation)  and should not be  considered  an indication or guarantee of
future  investment  results.  Year-to-year  fluctuations in certain markets have
been significant,  and negative returns have been experienced in certain markets
from time to time.  Stocks  are  measured  by the S&P 500  Index,  an  unmanaged
weighted  index  comprising  500  widely  held  common  stocks  and  varying  in
composition.  Unlike  investors in bonds and U.S.  Treasury bills,  common stock
investors do not receive fixed income payments and are not entitled to repayment
of principal. These differences contribute to investment risk. Returns shown for
long-term  government  bonds  are  based on U.S.  Treasury  bonds  with  20-year
maturities.  Inflation is measured by the Consumer Price Index.  The indexes are
unmanaged and are not available for investment.

      Over time, although subject to greater risks and higher volatility, stocks
have outperformed all other investments by a wide margin, offering a solid hedge
against  inflation.  From 1925 to 1998,  stocks beat all other traditional asset
classes. A $10,000  investment in the S&P 500 grew to $_________,  significantly
more than any other investment.

                                      TAXES

      BACKUP  WITHHOLDING.  The fund is required to withhold  31% of all taxable
dividends,  capital  gain  distributions  and  redemption  proceeds  payable  to
individuals and certain other non-corporate  shareholders who do not provide the
fund or PaineWebber with a correct taxpayer  identification number.  Withholding
at that rate also is required  from  dividends  and capital  gain  distributions
payable to those shareholders who otherwise are subject to backup withholding.

      SALE OR EXCHANGE OF FUND SHARES.  A  shareholder's  sale  (redemption)  of
shares  may  result  in a  taxable  gain  or  loss,  depending  on  whether  the
shareholder  receives more or less than his or her adjusted basis for the shares
(which  normally  includes any initial sales charge paid on Class A shares).  An
exchange  of the fund's  shares for shares of another  PaineWebber  mutual  fund
generally will have similar tax consequences.  In addition, if the fund's shares
are  bought  within 30 days  before or after  selling  other  shares of the fund
(regardless  of  class)  at a loss,  all or a  portion  of that loss will not be
deductible and will increase the basis of the newly purchased shares.

      SPECIAL RULE FOR CLASS A  SHAREHOLDERS.  A special tax rule applies when a
shareholder  sells or  exchanges  Class A shares  within 90 days of purchase and
subsequently  acquires Class A shares of the same or another  PaineWebber mutual
fund without paying a sales charge due to the 365-day reinstatement privilege or
the exchange privilege.  In these cases, any gain on the sale or exchange of the
original Class A shares would be increased,  or any loss would be decreased,  by
the amount of the sales  charge  paid when those  shares were  bought,  and that
amount  would  increase  the  basis  of  the  PaineWebber   mutual  fund  shares
subsequently acquired.

      QUALIFICATION AS A REGULATED  INVESTMENT  COMPANY.  To continue to qualify
for  treatment  as a regulated  investment  company  ("RIC")  under the Internal
Revenue Code, the fund must distribute to its shareholders for each taxable year
at least 90% of the sum of its investment  company  taxable  income  (consisting
generally of net  investment  income and net  short-term  capital gain) and must
meet several additional requirements.  These requirements include the following:
(1) the fund must derive at least 90% of its gross income each taxable year from
dividends,  interest,  payments with respect to securities  loans and gains from
the sale or other  disposition of securities,  or other income  (including gains
from  options or futures)  derived  with respect to its business of investing in
securities  ("Income  Requirement");  (2) at the  close of each  quarter  of the
fund's  taxable  year,  at least 50% of the value of its  total  assets  must be
represented by cash and cash items, U.S.  government  securities,  securities of
other RICs and other securities that are limited,  in respect of any one issuer,
to an amount  that does not exceed 5% of the value of the fund's  total  assets;
and (3) at the close of each quarter of the fund's  taxable year,  not more than
25% of the value of its total assets may be invested in  securities  (other than
U.S.  government  securities or the securities of other RICs) of any one issuer.
If the fund failed to qualify for treatment as a RIC for any taxable  year,  (a)
it would be taxed as an ordinary corporation on its taxable income for that year
(even  if  that  income  was  distributed  to  its  shareholders)  and  (b)  the
shareholders would treat all those distributions, including distributions of net
capital  gain (the  excess of net  long-term  capital  gain over net  short-term
capital  loss) as  dividends  (that is,  ordinary  income)  to the extent of the
fund's  earnings  and  profits.  In  addition,  the fund  could be  required  to
recognize  unrealized  gains,  pay  substantial  taxes  and  interest  and  make
substantial distributions before requalifying for RIC treatment.

      OTHER INFORMATION.  Dividends and other distributions declared by the fund
in October,  November or  December  of any year and payable to  shareholders  of
record on a date in any of those  months will be deemed to have been paid by the
fund  and  received  by the  shareholders  on  December  31 of that  year if the
distributions  are paid by the fund during the following  January.  Accordingly,
those  distributions  will be taxed to  shareholders  for the year in which that
December 31 falls.

      A portion of the  dividends  from the fund's  investment  company  taxable
income  (whether  paid in cash or  additional  shares) may be  eligible  for the
dividends-received  deduction allowed to corporations.  The eligible portion may
not exceed the aggregate dividends received by the fund from U.S.  corporations.
However,  dividends  received  by a  corporate  shareholder  and  deducted by it
pursuant  to the  dividends-received  deduction  are subject  indirectly  to the
alternative minimum tax.


                                       34
<PAGE>

      If fund shares are sold at a loss after being held for six months or less,
the loss will be treated as long-term,  instead of  short-term,  capital loss to
the extent of any capital gain distributions received on those shares. Investors
also should be aware that if shares are purchased shortly before the record date
for any dividend or capital gain  distribution,  the  shareholder  will pay full
price for the shares  and  receive  some  portion of the price back as a taxable
distribution.

      The fund will be subject to a  nondeductible  4% excise tax ("Excise Tax")
to the  extent  it  fails  to  distribute  by  the  end  of  any  calendar  year
substantially  all of its  ordinary  income for that year and  capital  gain net
income for the one-year  period ending on October 31 of that year,  plus certain
other amounts.

      The use of hedging strategies  involving Derivative  Instruments,  such as
writing (selling) and purchasing options and futures contracts, involves complex
rules that will  determine  for income tax  purposes the amount,  character  and
timing of  recognition  of the gains and losses the fund  realizes in connection
therewith.  Gains from  options and futures  contracts  derived by the fund with
respect to its business of investing in securities  will qualify as  permissible
income under the Income Requirement.

      The foregoing is only a general  summary of some of the important  federal
income tax considerations generally affecting the fund and its shareholders.  No
attempt is made to present a complete  explanation  of the federal tax treatment
of the fund's  activities,  and this  discussion is not intended as a substitute
for careful tax planning. Accordingly,  potential investors are urged to consult
their  own tax  advisers  for  more  detailed  information  and for  information
regarding  any  state,  local or  foreign  taxes  applicable  to the fund and to
dividends and distributions therefrom.

                                OTHER INFORMATION

      DELAWARE BUSINESS TRUST. The Trust is an entity of the type commonly known
as a Delaware  business  trust.  Although  Delaware law  statutorily  limits the
potential  liabilities of a Delaware  business trust's  shareholders to the same
extent  as it  limits  the  potential  liabilities  of a  Delaware  corporation,
shareholders of the fund could, under certain conflicts of laws jurisprudence in
various states,  be held  personally  liable for the obligations of the Trust or
the fund. However, the Trust's trust instrument disclaims  shareholder liability
for acts or  obligations of the Trust or its series (the fund) and requires that
notice of such disclaimer be given in each written  obligation made or issued by
the  trustees  or by any  officers  or officer  by or on behalf of the Trust,  a
series,  the  trustees or any of them in  connection  with the Trust.  The trust
instrument provides for indemnification  from the fund's property for all losses
and  expenses  of  any  series   shareholder  held  personally  liable  for  the
obligations of the fund. Thus, the risk of a shareholder's  incurring  financial
loss on account of shareholder  liability is limited to  circumstances  in which
the fund itself would be unable to meet its  obligations,  a  possibility  which
Mitchell  Hutchins  believes  is remote and not  material.  Upon  payment of any
liability  incurred by a shareholder  solely by reason of being or having been a
shareholder of the fund, the shareholder  paying such liability will be entitled
to  reimbursement  from the general assets of the fund.  The trustees  intend to
conduct  the  operations  of the  fund  in  such a way  as to  avoid,  as far as
possible, ultimate liability of the shareholders for liabilities of the fund.

      CLASSES OF SHARES.  A share of a class of the fund represents an identical
interest in its  investment  portfolio and has the same rights,  privileges  and
preferences.  However,  each class may differ with respect to sales charges,  if
any,  distribution  and/or  service  fees,  if  any,  other  expenses  allocable
exclusively to each class, voting rights on matters  exclusively  affecting that
class, and its exchange privilege, if any. The different sales charges and other
expenses  applicable to the different  classes of shares of the fund will affect
the  performance  of  those  classes.  Each  share of the  fund is  entitled  to
participate  equally in dividends,  other  distributions and the proceeds of any
liquidation of the fund. However,  due to the differing expenses of the classes,
dividends and liquidation proceeds on Class A, C and Y shares will differ.

      VOTING RIGHTS.  Shareholders of the fund are entitled to one vote for each
full share held and fractional votes for fractional  shares held.  Voting rights
are not  cumulative  and,  as a result,  the holders of more than 50% of all the
shares of the fund (so long as it is the sole series of the Trust) may elect all
of the  trustees  of the Trust.  The shares of the fund will be voted  together,


                                       35
<PAGE>

except that only the  shareholders of a particular class of the fund may vote on
matters  affecting only that class, such as the terms of a Rule 12b-1 Plan as it
relates to the class.

      The fund does not hold annual meetings.  Shareholders of record of no less
than  two-thirds  of the  outstanding  shares of the Trust may  remove a trustee
through  a  declaration  in  writing  or by vote cast in person or by proxy at a
meeting called for that purpose. A meeting will be called to vote on the removal
of the  trustee at the  written  request  of  holders of 10% of the  outstanding
shares of the Trust.

      CLASS-SPECIFIC EXPENSES. The fund may determine to allocate certain of its
expenses to the specific  classes of the fund's  shares to which those  expenses
are  attributable.  For example,  the fund's Class C shares bear higher transfer
agency  fees per  shareholder  account  than  those  borne by Class A or Class Y
shares.  The higher  fee is imposed  due to the  higher  costs  incurred  by the
transfer agent in tracking shares subject to a contingent  deferred sales charge
because, upon redemption,  the duration of the shareholder's  investment must be
determined to determine the applicable charge.  Although the transfer agency fee
will differ on a per account basis as stated above, the specific extent to which
the transfer  agency fees will differ between the classes as a percentage of net
assets is not  certain,  because the fee as a  percentage  of net assets will be
affected by the number of  shareholder  accounts in each class and the  relative
amounts of net assets in each class.

      CUSTODIAN AND  RECORDKEEPING  AGENT;  TRANSFER AND DIVIDEND  AGENT.  State
Street Bank and Trust  Company,  located at One Heritage  Drive,  North  Quincy,
Massachusetts  02171,  serves as custodian and recordkeeping agent for the fund.
PFPC Inc., a subsidiary  of PNC Bank,  N.A.,  serves as the fund's  transfer and
dividend disbursing agent. It is located at 400 Bellevue Parkway, Wilmington, DE

Item 24.  Persons Controlled by or Under Common Control with Registrant

          PaineWebber  Incorporated  ("PaineWebber"),  a  Delaware  corporation,
owned 69.7% of the  outstanding  securities of PaineWebber S&P 500 Index Fund as
of August 31, 1997.  PaineWebber  is a wholly owned  subsidiary  of Paine Webber
Group Inc.,  a publicly  owned  financial  services  holding  company.  Mitchell
Hutchins Asset Management Inc.  ("Mitchell  Hutchins"),  the investment adviser,
administrator  and  distributor  of the Trust,  is a wholly owned  subsidiary of
PaineWebber.  Paine Webber Group Inc.  and Mitchell  Hutchins  also are Delaware
corporations.

Item 25.  Indemnification

          Section 2 of  Article IX of the Trust  Instrument,  "Indemnification,"
provides  that the  appropriate  series of the  Registrant  will  indemnify  the
trustees and officers of the Registrant to the fullest  extent  permitted by law
against  claims and expenses  asserted  against or incurred by them by virtue of
being or having been a trustee or officer; provided that no such person shall be
indemnified  where there has been an  adjudication  or other  determination,  as
described  in Article IX, that such  person is liable to the  Registrant  or its
shareholders by reason of willful  misfeasance,  bad faith,  gross negligence or
reckless disregard of the duties involved in the conduct of his or her office or
did not act in good faith in the  reasonable  belief  that his action was in the
best interest of the Registrant.  Section 2 of Article IX also provides that the
Registrant   may   maintain   insurance   policies   covering   such  rights  of
indemnification.

          Additionally,  "Limitation of Liability" in Section 1 of Article IX of
the Trust  Instrument  provides that the trustees or officers of the  Registrant
shall not be personally  liable to any person extending  credit to,  contracting
with or having a claim against the Registrant or a particular  series; and that,
provided they have exercised reasonable care and have acted under the reasonable
belief  that their  actions  are in the best  interest  of the  Registrant,  the
trustees and officers  shall not be liable for neglect or  wrongdoing by them or
any officer,  agent,  employee,  investment adviser or independent contractor of
the Registrant.

          Section 9 of the Investment Advisory and Administration  Contract with
Mitchell  Hutchins Asset  Management Inc.  ("Mitchell  Hutchins")  provides that
Mitchell  Hutchins  shall not be liable for any error of  judgment or mistake of
law or for any loss suffered by any series of the Registrant in connection  with
the matters to which the Contract relates,  except for a loss resulting from the
willful misfeasance,  bad faith, or gross negligence of Mitchell Hutchins in the
performance of its duties or from its reckless  disregard of its obligations and
duties under the Contract. Section 10 of the Contract provides that the Trustees
shall not be liable for any  obligations  of the Trust or any  series  under the
Contract and that Mitchell  Hutchins  shall look only to the assets and property
of the Registrant in settlement of such right or claim and not to the assets and
property of the Trustees.

          Section 9 of each  Distribution  Contract provides that the Trust will
indemnify Mitchell Hutchins and its officers,  directors and controlling persons
against all  liabilities  arising from any alleged untrue  statement of material
fact in the Registration  Statement or from any alleged omission to state in the
Registration  Statement a material fact required to be stated in it or necessary
to make the  statements  in it, in light of the  circumstances  under which they
were made,  not  misleading,  except  insofar as  liability  arises  from untrue
statements or omissions made in reliance upon and in conformity with information
furnished  by  Mitchell  Hutchins  to the  Trust  for  use  in the  Registration
Statement; and provided that this indemnity agreement shall not protect any such
persons  against  liabilities  arising  by  reason  of their  bad  faith,  gross
negligence  or willful  misfeasance;  and shall not inure to the  benefit of any
such persons unless a court of competent  jurisdiction or controlling  precedent
determines  that such result is not against  public  policy as  expressed in the
Securities Act of 1933.  Section 9 of each  Distribution  Contract also provides
that  Mitchell  Hutchins  agrees to  indemnify,  defend and hold the Trust,  its
officers and Trustees free and harmless of any claims arising out of any alleged
untrue  statement  or  any  alleged  omission  of  material  fact  contained  in
information furnished by Mitchell Hutchins for use in the Registration Statement
or arising out of an agreement  between Mitchell Hutchins and any retail dealer,
or arising  out of  supplementary  literature  or  advertising  used by Mitchell
Hutchins  in  connection  with the  Contract.  Section  10 of each  Distribution
Contract contains  provisions  similar to Section 10 of the Investment  Advisory
and Administration  Contract, with respect to Mitchell Hutchins and PaineWebber,
as appropriate.

          Section  9 of each  Exclusive  Dealer  Agreement  contains  provisions
similar to Section 9 of each Distribution Contract,  with respect to PaineWebber
Incorporated ("PaineWebber").


                                      C-2
<PAGE>


          Insofar  as   indemnification   for  liabilities   arising  under  the
Securities  Act of 1933, as amended,  may be provided to trustees,  officers and
controlling persons of the Registrant,  pursuant to the foregoing  provisions or
otherwise, the Registrant has been advised that in the opinion of the Securities
and  Exchange  Commission  such  indemnification  is  against  public  policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for  indemnification  against  such  liabilities  (other than the payment by the
Registrant  of expenses  incurred or paid by a trustee,  officer or  controlling
person of the  Registrant  in  connection  with the  successful  defense  of any
action,  suit or  proceeding  or payment  pursuant to any  insurance  policy) is
asserted against the Registrant by such trustee,  officer or controlling  person
in connection with the securities being registered,  the Registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
