                         PaineWebber Money Market Fund
                   INVESTMENT OBJECTIVE, STRATEGIES AND RISKS
- --------------------------------------------------------------------------------

FUND OBJECTIVE

Maximum current income consistent with liquidity and conservation of capital.

PRINCIPAL INVESTMENT STRATEGIES


The fund is a money market fund. It seeks to maintain a stable price of $1.00
per share. To do this, the fund invests in a diversified portfolio of high
quality, short-term money market instruments. These investments include:


  commercial paper and other short-term obligations of corporations,
  partnerships, trusts and other entities


  U.S. government securities



  certificates of deposit and other bank obligations


  repurchase agreements


  investment company securities



Money market instruments are short-term debt obligations and similiar
securities. They also include longer term bonds that have variable interest
rates or other special features that give them the financial characteristics of
short-term debt.



The fund may invest in foreign money market instruments, but only if they are
denominated in U.S. dollars.



Mitchell Hutchins Asset Management Inc., the fund's investment adviser, selects
money market instruments for the fund based on its assessment of relative values
and changes in market and economic conditions.


PRINCIPAL RISKS

An investment in the fund is not a bank deposit and is neither insured nor
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. While the fund seeks to maintain the value of your investment at $1.00
per share, it is possible to lose money by investing in the fund.


Money market instruments generally have a low risk of loss, but they are not
risk free. The fund is subject to credit risk, which is that issuers may fail,
or become less able, to make payments when due. The fund also is subject to
interest rate risk. When short-term interest rates rise, the value of the fund's
investments generally will fall, and its yield will tend to lag behind
prevailing rates.



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:


  Credit Risk

  Interest Rate Risk

  Foreign Securities Risk

Information on the fund's recent holdings can be found in its current
annual/semi-annual reports (see back cover for information on ordering those
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
bar chart shows Class B shares because they have the longest performance history
of any class of fund shares. The bar chart does not reflect the effect of sales
charges; if it did, the total returns shown would be lower.

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

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. 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.


Credit Risk. Credit risk is the risk that the issuer of a money market
instrument will not make principal or interest payments when they are due. Even
if an issuer does not default on a payment, a money market instrument's value
may decline if the market believes that the issuer has become less able, or less
willing, to make payments on time. Even the highest quality money market
instruments are subject to some credit risk.



Interest Rate Risk. The value of money market instruments generally can be
expected to fall when interest rates rise and to rise when interest rates fall.
Interest rate risk is the risk that interest rates will rise, so that the value
of the fund's investments will fall. In addition, the fund's yield will tend to
lag behind changes in prevailing short-term interest rates. This means that the
fund's income will tend to rise more slowly than increases in short-term
interest rates. Similarly, when short-term interest rates are falling, the
fund's income will tend to fall more slowly.


Foreign Securities Risk. 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 other service providers that they are taking similar steps.

Similarly, the issuers whose money market instruments are bought by the fund and
the trading systems used by the fund could be adversely affected by this issue.
The ability of an issuer 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.

ADDITIONAL INVESTMENT STRATEGIES


Like all money market funds, the fund is subject to maturity, quality and
diversification requirements designed to help it maintain a stable price of
$1.00 per share. In addition, Mitchell Hutchins may employ a number of
professional money management techniques to respond to changing economic and
money market conditions and to shifts in fiscal and monetary policy. These
techniques include varying the composition and

money markets.

FLEXIBLE PRICING

The fund offers three classes of shares -- Class A, Class B and Class C --
solely through exchange for shares of the corresponding class of other
PaineWebber funds. No front-end sales charge is imposed when fund shares are
acquired through an exchange, and no contingent deferred sales charge is imposed
when shares of another PaineWebber fund are exchanged for the fund's shares.


The fund and the other PaineWebber funds that use the Flexible Pricing system
have adopted plans under rule 12b-1 for their Class A, Class B and Class C
shares that allow each fund to pay service fees for services provided to
shareholders and (for Class B and Class C shares) distribution fees for the sale
of its shares. Because the 12b-1 distribution fees for Class B and Class C
shares are paid out of a 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 sales charge.


CLASS A SHARES

Class A shares of the fund have no front-end sales charge because they are
acquired through an exchange for Class A shares of another PaineWebber fund.
Class A shares of other PaineWebber funds generally have a front-end sales
charge that is included in their offering price and is not invested in a fund.
Class A shares of the fund 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 B and Class C shares.

You may have to pay a 1% contingent deferred sales charge when you sell Class A
shares of the fund if:

  The front-end sales charge was waived for the Class A shares you exchanged for
  fund shares because your initial purchase was $1 million or more and

  You sell your Class A shares of the fund within one year of the initial
  purchase date for the Class A shares that you later exchanged for fund shares.

This deferred sales charge would be 1% of the lesser of the offering price of
the Class A shares initially purchased or the net asset value of the Class A
shares of the fund at the time of sale. We will not impose the deferred sales
charge on Class A shares representing reinvestment of dividends or on
withdrawals in the first year after purchase of up to 12% of the value of your
Class A 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 B SHARES


Class B shares have a contingent deferred sales charge. When you initially
purchase Class B shares of a PaineWebber fund, we invest 100% of your purchase
and no deferred sales charge is imposed when you exchange those shares for

Class B shares of the fund. However, you may have to pay the deferred sales
charge when you sell your fund shares, depending on how long you own the shares.


The fund's Class B shares pay an annual 12b-1 distribution fee of 0.50% of
average net assets, as well as an annual 12b-1 service fee of 0.25% of average
net assets. If you hold your Class B shares for six years after the initial
purchase date for the original Class B shares that you later exchanged for fund
shares, they will automatically convert to Class A shares of the fund. Class A
shares have lower ongoing expenses.


You will pay a deferred sales charge if you sell Class B shares before the end
of six years (four years for fund shares acquired in certain exchanges for
Class B shares of PaineWebber Low Duration U.S. Government Income Fund). We
calculate the deferred sales charge by multiplying the lesser of the net asset
value of the Class B shares initially purchased or the net asset value of the
Class B shares of the fund at the time of sale by the percentage shown below:

We will not impose the deferred sales charge on Class B shares representing
reinvestment of dividends or on withdrawals in any year of up to 12% of the
value of your Class B shares under the Systematic Withdrawal Plan.

To minimize your deferred sales charge, we will assume that you are selling:

  First, Class B shares representing reinvested dividends, and

  Second, Class B shares that you have owned the longest.

Sales Charge Waivers. You may qualify for a waiver of the deferred sales charge
on a sale of shares if:

  You participate in the Systematic Withdrawal Plan;

  You are older than 59 1/2 and are selling shares to take a distribution from
  certain types of retirement plans;

  You receive a tax-free return of an excess IRA contribution;

  You receive a tax-qualified retirement plan distribution following retirement;
  or

  The shares are sold within one year of your death and you owned the shares
  either (1) as the sole shareholder or (2) with your spouse as a joint tenant
  with the right of survivorship.

Note: If you think you qualify for any of these sales charge 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 Systematic Withdrawal Plan,

CLASS C SHARES

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

The fund's Class C shares pay an annual 12b-1 distribution fee of 0.50% of
average net assets, as well as an annual 12b-1 service fee of 0.25% of average
net assets. 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.

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 initially purchased the Class C shares that you later exchanged for fund
shares. The deferred sales charge will be either 0.75% or 1.00%, depending on
the deferred sales charge that would have applied to the initially purchased
Class C shares. We calculate the deferred sales charge on sales of Class C
shares by multiplying 0.75% or 1.00% (as applicable) by the lesser of the net
asset value of the Class C shares initially purchased or the net asset value of
the Class C shares of the fund 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.

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 B.

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

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:

  Your name and address;

  The fund's name;

  The fund account number;

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

Within three business days after receipt of the request, sales proceeds (less
any applicable contingent deferred sales charge) will be paid by check or
credited to the shareholder's brokerage account at the election of the
shareholder.


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, Class B or Class C shares of the fund for shares of
the same class of most other PaineWebber funds.

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. Each fund will use the date
that you initially purchased the exchanged shares 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.

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:

  Your name and address;

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

  Your account number;

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

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

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

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

PRICING AND VALUATION


The price of fund shares is based on net asset value. The net asset value is the
total value of the fund divided by the total number of shares outstanding. In
determining net asset value, the fund values its securities at their amortized
cost. This method uses a constant amortization to maturity of the difference
between the cost of the instrument to the fund and the amount due at maturity.
The fund's net asset value per share is expected to be $1.00, although this
value is not guaranteed.



The fund calculates net asset value on days that the New York Stock Exchange
(NYSE) 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 deferred sales charge may apply when you sell
Class B or Class C shares.

DIVIDENDS AND TAXES


Dividends. The fund declares dividends daily and pays them monthly. The fund
distributes any net short-term capital gain annually, but may make more frequent

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 corresponding 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.


The fund expects that its dividends will be taxed primarily as ordinary income.
The fund will tell you how you should treat its dividends for tax purposes. You
will not recognize any gain or loss on the sale or exchange of your fund shares
so long as the fund maintains a share price of $1.00.

(1) Total investment return is calculated assuming a $1,000 investment in Fund
    shares on the first day of each year reported, reinvestment of all dividends
    and other distributions at net asset value on the payable dates, and a sale
    at net asset value on the last day of each year reported. The figures do not
    include sales charges; results for each class would be lower if sales
    charges were included.

                      THE FUND AND ITS INVESTMENT POLICIES

        The fund's investment objective may not be changed without shareholder
approval. Except where noted, the other investment policies of the fund may be
changed by its board without shareholder approval. As with other mutual funds,
there is no assurance that the fund will achieve its investment objective.


        The fund's investment objective is to provide maximum current income
consistent with liquidity and conservation of capital. The fund invests in high
quality money market instruments that have, or are deemed to have, remaining
maturities of 13 months or less. These instruments include (1) U.S. and foreign
government securities, (2) obligations of U.S. and foreign banks, (3) commercial
paper and other short-term obligations of U.S. and foreign corporations,
partnerships, trusts and similar entities, (4) funding agreements and other
insurance company obligations, (5) repurchase agreements regarding any of the
foregoing and (6) investment company securities. Money market instruments are
short-term debt-obligations and similar securities. They also include longer
term bonds that have variable interest rate or other special features that give
them the financial characteristics of short-term debt. The fund maintains a
dollar-weighted average portfolio maturity of 90 days or less.



        The fund may invest in obligations (including certificates of deposit,
bankers' acceptances, time deposits and similar obligations) of U.S. and foreign
banks only if the institution has total assets at the time of purchase in excess
of $1.5 billion. The fund may invest in non-negotiable time deposits of U.S.
banks, savings associations and similar depository institutions only if the
institution has total assets at the time of purchase in excess of $1.5 billion
and the time deposit has a maturity of seven days or less.



        The fund may purchase only those obligations that Mitchell Hutchins
determines, pursuant to procedures adopted by the board, present minimal credit
risks and are "Eligible Securities" as defined in Rule 2a-7 under the Investment
Company Act, as amended ("Investment Company Act"). Eligible Securities include
securities rated in one of the two highest short-term ratings categories by at
least two nationally recognized statistical rating organizations ("rating
agencies") or rated in one of the two highest short-term ratings categories by a
single rating agency if only that rating agency has assigned the obligation a
short-term rating. The fund also may rely on the short-term rating and credit
quality of a guarantee of a security (including bond insurance, letters of
credit or an unconditional demand feature) or the issuer of the guarantee to
determine whether the security is an Eligible Security. Eligible Securities also
include unrated securities that Mitchell Hutchins determines to be of comparable
quality to rated securities that so qualify.



        "Second Tier Securities" are Eligible Securities that are not rated in
the highest short-term ratings category by the requisite rating agencies or
determined by Mitchell Hutchins to be of comparable quality and do not otherwise
qualify for treatment as "First Tier Securities" under Rule 2a-7. (A definition
of First Tier Securities is set forth below.) The fund may invest no more than
5% of its total assets in Second Tier Securities and may invest no more than the
greater of 1% of its total assets or $1 million in Second Tier Securities of a
single issuer. Although the fund may invest in Second Tier Securities of U.S.
companies, it does not purchase commercial paper of foreign companies,
governments and similar entities falling into this category. Further, the fund
generally may invest no more than 5% of its total assets in the securities of a
single issuer (other than U.S. government securities). The fund may purchase
only U.S. dollar-denominated obligations of foreign issuers.



        The fund may invest up to 10% of its net assets in illiquid securities.
It may purchase securities on a when-issued or delayed delivery basis. The fund
may lend its portfolio securities to qualified broker-dealers or institutional
investors in an amount up to 33-1/3% of its total assets. The fund may borrow up
to 10% of its total assets for temporary purposes, including reverse repurchase
agreements. It may invest in the securities of other investment companies.

              THE FUND'S INVESTMENTS, RELATED RISKS AND LIMITATIONS


        The following supplements the information contained in the Prospectus
and above concerning the fund's investments, related risks and limitations.
Except as otherwise indicated in the Prospectus or the SAI, the fund has
established no policy limitations on its ability to use the investments or
techniques discussed in these documents.



        YIELDS AND CREDIT RATINGS OF MONEY MARKET INSTRUMENTS. The yields on the
money market instruments in which the fund invests are dependent on a variety of
factors, including general money market conditions, conditions in the particular
market for the obligation, the financial condition of the issuer, the size of
the offering, the maturity of the obligation and the ratings of the issue. The
ratings assigned by rating agencies represent their opinions as to the quality
of the obligations they undertake to rate. Ratings, however, are general and are
not absolute standards of quality. Consequently, obligations with the same
rating, maturity and interest rate may have different market prices.


        Subsequent to its purchase by the fund, an issue may cease to be rated
or its rating may be reduced. If a security in the fund's portfolio ceases to be
a First Tier Security (as defined below) or Mitchell Hutchins becomes aware that
a security has received a rating below the second highest rating by any rating
agency, Mitchell Hutchins and, in certain cases, the fund's board, will consider
whether the fund should continue to hold the obligation. A First Tier Security
is either (1) rated in the highest short-term rating category by at least two
rating agencies, (2) rated in the highest short-term rating category by a single
rating agency if only that rating agency has assigned the obligation a
short-term rating, (3) issued by an issuer that has received such a short-term
rating with respect to a security that is comparable is priority and security,
(4) subject to a guarantee rated in the highest short-term rating category or
issued by a guarantor that has received the highest short-term rating for a
comparable debt obligation or (5) unrated, but determined by Mitchell Hutchins
to be of comparable quality. A First Tier Security rated in the highest
short-term category at the time of purchase that subsequently receives a rating
below the highest rating category from a different rating agency may continue to
be considered a First Tier Security.

        U.S. GOVERNMENT SECURITIES include direct obligations of the U.S.
Treasury (such as Treasury bills, notes or bonds) and obligations issued or
guaranteed as to principal and interest (but not as to market value) by the U.S.
government, its agencies or its instrumentalities. U.S. government securities
include mortgage-backed securities issued or guaranteed by government agencies
or government-sponsored enterprises. Other U.S. government securities may be
backed by the full faith and credit of the U.S. government or supported
primarily or solely by the creditworthiness of the government-related issuer or,
in the case of mortgage-backed securities, by pools of assets.

        U.S. government securities also include separately traded principal and
interest components of securities issued or guaranteed by the U.S. Treasury,
which are traded independently under the Separate Trading of Registered Interest
and Principal of Securities ("STRIPS") program. Under the STRIPS programs, the
principal and interest components are individually numbered and separately
issued by the U.S. Treasury.


        COMMERCIAL PAPER AND OTHER SHORT-TERM OBLIGATIONS. The fund may purchase
commercial paper, which includes short-term obligations issued by corporations,
partnerships, trusts or other entities to finance short-term credit needs. The
fund also may purchase other types of non-convertible debt obligations subject
to maturity constraints imposed by Rule 2a-7 under the Investment Company Act of
1940, as amended ("Investment Company Act"). Descriptions of certain types of
short-term obligations are provided below.



        ASSET-BACKED SECURITIES. The fund may invest in securities that are
comprised of financial assets. Such assets may include motor vehicle and other
installment sales contracts, home equity loans, leases of various types of real
and personal property and receivables from revolving credit (credit card)
agreements or other types of financial assets. Such assets are securitized
through the use of trusts or special purpose corporations or other entities.
Payments or distributions of principal and interest may be guaranteed up to a
certain amount and for a certain time period by a letter of credit or pool
insurance policy issued by a financial institution unaffiliated with the issuer,
or other credit enhancements may be present. See "The Fund's Investments,
Related Risks and Limitations -- Credit and Liquidity Enhancements."



                                       3




<PAGE>




        VARIABLE AND FLOATING RATE SECURITIES AND DEMAND INSTRUMENTS. The fund
may purchase variable and floating rate securities with remaining maturities in
excess of 13 months issued by U.S. government agencies or instrumentalities or
guaranteed by the U.S. government. In addition, the fund may purchase variable
and floating rate securities of other issuers with remaining maturities in
excess of 13 months if the securities are subject to a demand feature
exercisable within 13 months or less. The yields on these securities are
adjusted in relation to changes in specific rates, such as the prime rate, and
different securities may have different adjustment rates. The fund's investment
in these securities must comply with conditions established by the Securities
and Exchange Commission ("SEC") under which they may be considered to have
remaining maturities of 13 months or less. Certain of these obligations carry a
demand feature that gives the fund the right to tender them back to a specified
party, usually the issuer or a remarketing agent, prior to maturity. See "The
Fund's Investments, Related Risks and Limitations -- Credit and Liquidity
Enhancements."



        Generally, the fund may exercise demand features (1) upon a default
under the terms of the underlying security, (2) to maintain its portfolio in
accordance with its investment objective and policies or applicable legal or
regulatory requirements or (3) as needed to provide liquidity to the fund in
order to meet redemption requests. The ability of a bank or other financial
institution to fulfill its obligations under a letter of credit, guarantee or
other liquidity arrangement might be affected by possible financial difficulties
of its borrowers, adverse interest rate or economic conditions, regulatory
limitations or other factors. The interest rate on floating rate or variable
rate securities ordinarily is readjusted on the basis of the prime rate of the
bank that originated the financing or some other index or published rate, such
as the 90-day U.S. Treasury bill rate, or is otherwise reset to reflect market
rates of interest. Generally, these interest rate adjustments cause the market
value of floating rate and variable rate securities to fluctuate less than the
market value of fixed rate securities.



        VARIABLE AMOUNT MASTER DEMAND NOTES. The fund may invest in variable
amount master demand notes, which are unsecured redeemable obligations that
permit investment of varying amounts at fluctuating interest rates under a
direct agreement between the fund and an issuer. The principal amount of these
notes may be increased from time to time by the parties (subject to specified
maximums) or decreased by the fund or the issuer. These notes are payable on
demand and may or may not be rated.


        INVESTING IN FOREIGN SECURITIES. The fund's investments in U.S.
dollar-denominated securities of foreign issuers may involve risks that are
different from investments in U.S. issuers. These risks may include future
unfavorable political and economic developments, possible withholding taxes,
seizure of foreign deposits, currency controls, interest limitations or other
governmental restrictions that might affect the payment of principal or interest
on the fund's investments. Additionally, there may be less publicly available
information about foreign issuers because they may not be subject to the same
regulatory requirements as domestic issuers.


        CREDIT AND LIQUIDITY ENHANCEMENTS. The fund may invest in securities
that have credit or liquidity enhancements or the fund may purchase these types
of enhancements in the secondary market. Such enhancements may be structured as
demand features that permit the fund to sell the instrument at designated times
and prices. These credit and liquidity enhancements may be backed by letters of
credit or other instruments provided by banks or other financial institutions
whose credit standing affects the credit quality of the underlying obligation.
Changes



                                       4

in the credit quality of these financial institutions could cause losses to the
fund. The credit and liquidity enhancements may have conditions that limit the
ability of the fund to use them when the fund wishes to do so.



        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, 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 board. To the extent the fund invests in illiquid securities,
it may not be able readily to liquidate such investments and may have to sell
other investments if necessary to raise cash to meet its obligations.


        Restricted securities are not registered under the Securities Act of
1933, as amended ("Securities Act"), and may be sold only in privately
negotiated or other exempted transactions or after a registration statement
under the Securities Act 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 Securities Act. Institutional investors generally will
not seek to sell these instruments to the general public, but instead will often
depend 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 Securities 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 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 and (4) the
existence of demand features or similar liquidity enhancements. Mitchell
Hutchins monitors the liquidity of restricted securities in the fund's portfolio
and reports periodically on such decisions to the board.


        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 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


                                       5




<PAGE>




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 its 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. 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. See "The Fund's Investments, Related Risks and
Limitations -- Segregated Accounts."

        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. If 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 that 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.


        WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The fund may purchase
securities 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
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 a loss or missing an opportunity to make an
alternative investment.



        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 commits 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.



        INVESTMENTS IN OTHER INVESTMENT COMPANIES. The fund may invest in
securities of other money market funds, subject to Investment Company Act
limitations, which at present restrict these investments in the aggregate to no
more than 10% of the fund's total assets. The shares of other money market funds
are subject to the management fees and other expenses of those funds. At the
same time, the fund would continue to pay its own management fees and expenses
with respect to all its investments, including shares of other money market
funds. The fund may invest in the securities of other money market funds when
Mitchell Hutchins believes that (1) the amounts to be invested are too small or
are available too late in the day to be effectively invested in other money
market instruments, (2) shares of other money market funds otherwise would
provide a better return than direct investment in other money market instruments
or (3) such investments would enhance the fund's liquidity.


        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


                                       6




<PAGE>




limited to cash, U.S. government securities and irrevocable letters of credit
that meet certain guidelines established by Mitchell Hutchins. The fund may
reinvest any cash collateral in money market investments 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 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 acted as lending agent. PaineWebber also has
been approved as a borrower under the fund's securities lending program.

        SEGREGATED ACCOUNTS. When the fund enters into certain transactions that
involve obligations to make future payments to third parties, including the
purchase of securities on a when-issued or delayed delivery basis or reverse
repurchase agreements, 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.


INVESTMENT LIMITATIONS OF THE FUND

        FUNDAMENTAL 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 shares of the fund present at a shareholders' meeting if more than
50% of the outstanding 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, later changes 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 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 securities issued or guaranteed by the U.S.
government, its agencies or instrumentalities or to municipal securities or to
certificates of deposit and bankers' acceptances of domestic branches of U.S.
banks.


        The following interpretations apply to, but are not a part of, this
fundamental restriction: (a) domestic and foreign banking will be considered to
be different industries, and (b) asset-backed securities will be grouped in
industries based upon their underlying assets and not treated as constituting a
single, separate industry.

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

        (3) 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


                                       7




<PAGE>



paper, certificates of deposit, bankers' acceptances or similar instruments will
not be considered the making of a loan.

        The following interpretation applies to, but is not part of, this
fundamental restriction: the fund's investments in master notes, funding
agreements and similar instruments will not be considered to be the making of a
loan.

        (4) 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.

        (5) 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.

        (6) 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.

        (7) 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.

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


        (2) 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.

        (3) 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.


        (4) purchase securities of other investment companies, except to the
extent permitted by the Investment Company Act 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.

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

        The Corporation pays each board member who is not an "interested person"
of the Corporation $1,000 annually for the fund and $1,500 annually for the
Corporation's second series and an additional amount up to $150 per series for
each board meeting and each separate meeting of a board committee. Therefore,
the Corporation pays each such trustee $2,500 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 board members are reimbursed for any expenses incurred in
attending meetings. Board members and officers own in the aggregate less than 1%
of the outstanding shares of any class of the fund. Because PaineWebber and
Mitchell Hutchins perform substantially all the services necessary for the
operation of the Corporation and the fund, the Corporation requires no
employees. No officer, director or employee of Mitchell Hutchins or PaineWebber
presently receives any compensation from the Corporation for acting as a board
member or officer.

           INVESTMENT ADVISORY, ADMINISTRATION AND DISTRIBUTION ARRANGEMENTS




        INVESTMENT ADVISORY AND ADMINISTRATION ARRANGEMENTS. Mitchell Hutchins
acts as the investment adviser and administrator to the fund pursuant to a
contract dated August 4, 1988 ( "Advisory Contract") with the Corporation. Under
the Advisory Contract, the fund pays Mitchell Hutchins a fee, computed daily and
paid monthly, at the annual rate of 0.50% of its average daily net assets.



        During the fiscal years ended February 28, 1999, February 28, 1998 and
February 28, 1997, the fund paid (or accrued) investment advisory and
administrative fees of $314,378, $202,449 and $215,423, respectively.


        Prior to August 1, 1997, PaineWebber provided certain services to the
fund not otherwise provided by its transfer agent. Pursuant to a separate
agreement between PaineWebber and the Corporation relating to those services,
PaineWebber earned (or accrued) $5,548 for the period March 1, 1997 to July 31,
1997 and $13,300 for the fiscal year ended February 28, 1997. Subsequent to July
31, 1997, PFPC (not the fund) pays PaineWebber for certain transfer agency
related services that PFPC has delegated to PaineWebber.


        Under the terms of the Advisory Contract, the fund bears all expenses
incurred in its operation that are not specifically assumed by Mitchell
Hutchins. General expenses of the Corporation not readily identifiable as
belonging to the fund or to the Corporation's other series are allocated among
series by or under the direction of the board in such manner as the board deems
fair and equitable. Expenses borne by the fund include the following: (1) the
cost (including brokerage commissions) of securities purchased or sold by the
fund and any losses incurred in connection therewith; (2) fees payable to and
expenses incurred on behalf of the fund by Mitchell Hutchins; (3) organizational
expenses; (4) filing fees and expenses relating to the registration and
qualification of the fund's shares under federal and state securities laws and
maintenance of such registrations and qualifications; (5) fees and salaries
payable to board members and officers who are not interested persons (as defined
in the Investment Company Act) of the Corporation or Mitchell Hutchins; (6) all
expenses incurred in connection with the board members' services, including
travel expenses; (7) taxes (including any income or franchise taxes) and
governmental fees; (8) costs of any liability, uncollectible items of deposit
and other insurance or fidelity bonds; (9) any costs, expenses or losses arising
out of a liability of or claim for damages or other relief asserted against the
Corporation or fund for violation of any law; (10) legal, accounting and
auditing expenses, including legal fees of special counsel for the independent
board members; (11) charges of custodians, transfer agents and other agents;
(12) expenses of setting in type and printing prospectuses, statements of
additional information and supplements thereto, reports and proxy materials for
existing shareholders, and costs of mailing such materials to shareholders; (13)
any extraordinary expenses (including fees and disbursements of counsel)
incurred by the fund; (14) fees, voluntary assessments and other expenses
incurred in connection with membership in investment company organizations; (15)
Costs of mailing and tabulating proxies and costs of meetings of shareholders,
the board and any committees thereof; (16) the cost of investment company
literature and other publications provided to board members and officers; and
(17) costs of mailing, stationery and communications equipment.


        Under the Advisory Contract, Mitchell Hutchins will not be liable for
any error of judgment or mistake of law or for any loss suffered by the
Corporation or the fund in connection with the performance of the Advisory
Contract, except a loss resulting from willful misfeasance, bad faith or gross
negligence on the part of Mitchell Hutchins in the performance of its duties or
from reckless disregard of its duties and obligations thereunder. The Advisory
Contract terminates automatically upon assignment and is terminable at any time
without penalty by the board or by vote of the holders of a majority of the
fund's outstanding voting securities on 60 days' written notice to Mitchell
Hutchins, or by Mitchell Hutchins on 60 days' written notice to the Corporation.


        During the fiscal years ended February 28, 1999 and February 28, 1998,
the fund paid (or accrued) no fees to PaineWebber for its services as securities
lending agent.

        PERSONAL 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
Corporation (collectively, "Distribution Contracts"). Each Distribution Contract
requires 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 of the fund
(collectively, "Exclusive Dealer Agreements"), PaineWebber and its correspondent
firms sell the fund's shares.


        Under separate plans of distribution pertaining to the Class A, Class B
and Class C shares of the fund adopted by the Corporation in the manner
prescribed under Rule 12b-1 under the Investment Company Act (each,
respectively, the "Class A Plan," "Class B Plan" and "Class C Plan," and
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 each class of shares. Under the Class B Plan, the fund pays Mitchell
Hutchins a distribution fee, accrued daily and payable monthly, at the annual
rate of 0.50% of the average daily net assets of the Class B shares. Under the
Class C Plan, the fund pays Mitchell Hutchins a distribution fee, accrued daily
and payable monthly, at the annual rate of 0.50% of the average daily net assets
of the Class C shares.



        Mitchell Hutchins uses the service fees under the Plans for Class A, B
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. These expenses may
include the costs of the PaineWebber branch office in which the Financial
Advisor is based, such as rent, communications equipment, employee salaries and
other overhead costs.



                                       18




<PAGE>




        Mitchell Hutchins uses the distribution fees under the Class B and Class
C Plans to offset the fund's marketing costs attributable to those classes, such
as the preparation, printing and distribution of sales literature and
advertising and printing and distributing prospectuses and other shareholder
materials to prospective investors. PaineWebber also may use distribution fees
to pay additional compensation to PaineWebber and other costs allocated to
Mitchell Hutchins' and PaineWebber's distribution activities, including employee
salaries and bonuses and othr overhead expenses. These expenses may include the
branch office costs noted above. Because fund shares may be acquired only
through an exchange of shares of other PaineWebber funds, Mitchell Hutchins does
not pay commissions to PaineWebber for selling fund shares.


        Mitchell Hutchins receives the proceeds 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, Class B
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 any Plan will be Mitchell Hutchins' sole responsibility and
not that of the fund. Annually, the board reviews the Plans and Mitchell
Hutchins' corresponding expenses for each class of fund shares separately from
the Plans and expenses of the other classes.

        Among other things, each Plan provides that (1) Mitchell Hutchins will
submit to the board at least quarterly, and the board members 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 board members who are not "interested
persons" of the Corporation 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 board
members who are not "interested persons" of the Corporation shall be committed
to the discretion of the board members who are not "interested persons" of that
Corporation.

        In reporting amounts expended under the Plans to the board members,
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 three classes of shares. The fees paid by one class of
the fund's shares will not be used to subsidize the sale of any other class of
fund shares.


        During the fiscal year ended February 28, 1999, the fund paid (or
accrued) service and/or distribution fees to Mitchell Hutchins under the Plans
as follows: Class A -- $88,231, Class B -- $134,452 and Class C -- $72,413.


        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 February 28, 1999:

        "Marketing and advertising" includes various internal costs allocated by
Mitchell Hutchins to its efforts at distributing the fund's shares. These
internal costs encompass office rent, salaries and other overhead expenses of
various departments and areas of operations of Mitchell Hutchins. "Branch
network costs allocated and interest expense" consist of an allocated portion of
the expenses of various PaineWebber departments involved in the distribution of
the fund's shares, including the PaineWebber retail branch system.

        In approving the Class A Plan, the board considered all the features of
the distribution system, including (1) the benefit to the fund and its
shareholders of the fund being available as an exchange vehicle for the Class A
shares of other PaineWebber funds such that Class A fund shares could be
exchanged with Class A shares of other PaineWebber funds without an initial
sales charge being incurred, (2) the advantages to the shareholders of economies
of scale resulting from growth in the fund's assets and potential continued
growth, (3) the services provided to the fund and its shareholders by Mitchell
Hutchins, (4) the services provided by PaineWebber pursuant to its Exclusive
Dealer Agreement with Mitchell Hutchins and (5) Mitchell Hutchins' shareholder
service-related expenses and costs.

        In approving the Class B Plan, the board of the fund considered all the
features of the distribution system, including (1) the conditions under which
contingent deferred sales charges would be imposed and the amount of such
charges, (2) the benefit to the fund and its shareholders of the fund being
available as an exchange vehicle for shares of the corresponding class of other
PaineWebber funds such that Class B fund shares could be exchanged with shares
of the corresponding class of other PaineWebber funds without a contingent
deferred sales charge being incurred, (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- and distribution-related expenses and costs.


        In approving the Class C Plan, the board considered all the features of
the distribution system, including (1) the benefit to the fund and its
shareholders of the fund being available as an exchange vehicle for shares of
the corresponding class of other PaineWebber funds, (2) the advantage to
investors in 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 do not face
contingent deferred sales charges if the shares are held for more than one year,
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 advantages 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, (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 after one year following purchase 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 fees and, as applicable, distribution fees and contingent
deferred sales charges. The board also considered the benefits that would accrue
to Mitchell Hutchins under each Plan in that Mitchell Hutchins would receive
service, distribution and advisory fees that are calculated based upon a
percentage of the average net assets of the fund, which fees would increase if
the Plan were successful and the fund attained and maintained significant asset
levels.

        Mitchell Hutchins earned and retained the following contingent deferred
sales charges paid upon certain redemptions of shares for the fiscal year ended
February 28, 1999:

</TABLE>



                                PORTFOLIO TRANSACTIONS


         ** 1 The fund purchases portfolio securities from dealers and
underwriters as well as from issuers. Securities are usually traded on a net
basis with dealers acting as principal for their own accounts without a stated
commission. Prices paid to dealers in principal transactions 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. When securities
are purchased directly from an issuer, no commissions or discounts are paid.
When securities are purchased in underwritten offerings, they include a fixed
amount of compensation to the underwriter.



         The Advisory Contract authorizes Mitchell Hutchins (with the approval
of the board) to select brokers and dealers to execute purchases and sales of
the fund's portfolio securities. The Advisory Contract directs Mitchell Hutchins
to use its best efforts to obtain the best available price and most favorable
execution with respect to all transactions for the fund. To the extent that the
execution and price offered by more than one dealer are comparable, Mitchell
Hutchins may, in its discretion, effect transactions in portfolio securities
with dealers who provide the fund with research, analysis, advice and similar
services. Although Mitchell Hutchins may receive certain research or execution
services in connection with these transactions, Mitchell Hutchins will not
purchase securities at a higher price or sell securities at a lower price than
would otherwise be paid had no services been provided by the executing dealer.
Moreover, Mitchell Hutchins will not enter into any explicit soft dollar
arrangements relating to principal transactions and will not receive in
principal transactions the types of services that could be purchased for hard
dollars. Research services furnished by the dealers through which or with which
the fund effects securities transactions may be used by Mitchell Hutchins in
advising other funds or accounts it advises and, conversely, research services
furnished to Mitchell Hutchins in connection with other funds or accounts that
Mitchell Hutchins advises may be used in advising the fund. Information and
research received from dealers will be in addition to, and not in lieu of, the
services required to be performed by Mitchell Hutchins under the Advisory
Contract.



        During the last three fiscal years, the fund paid no brokerage
commissions. Therefore, the fund has not allocated any brokerage transactions
for research, analysis, advice and similar services.



         Mitchell Hutchins may engage in agency transactions in over-the-counter
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 a requirement that Mitchell Hutchins obtain
multiple quotes from dealers before executing the transactions on an agency
basis.


* 1 moved from here; text not shown

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.

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

        WAIVERS OF CONTINGENT DEFERRED SALES CHARGES -- CLASS B SHARES. Among
other circumstances, the contingent deferred sales charge on Class B shares is
waived where a total or partial redemption is made within one year following the
death of the shareholder. The contingent deferred sales charge waiver is
available where the decedent is either the sole shareholder or owns the shares
with his or her spouse as a joint tenant with right of survivorship. This waiver
applies only to redemption of shares held at the time of death.

        ADDITIONAL EXCHANGE AND REDEMPTION INFORMATION. As discussed in the
Prospectus, shares of the fund may be exchanged for shares of the corresponding
class of most other PaineWebber funds.


        Shareholders will receive at least 60 days' notice of any termination or
material modification of the exchange privilege, except no notice need be given
if, under extraordinary circumstances, either redemptions are suspended under
the circumstances described below or the fund temporarily delays or ceases the
sales of its shares because it is unable to invest amounts effectively in
accordance with its 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 it 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 has
elected, however, to be governed by Rule 18f-1 under the Investment Company Act,
under which it is obligated to redeem shares solely in cash up to the lesser of
$250,000 or 1% of its net asset value during any 90-day period for one
shareholder. This election is irrevocable unless the SEC permits its withdrawal.



        The fund may suspend redemption privileges or postpone the date of
payment during any period (1) when the New York Stock Exchange ("NYSE") is
closed or trading on the NYSE 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 a 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.


                                       22




<PAGE>



        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:

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

               Class B shares. Minimum value of fund shares is $20,000; minimum
               monthly, quarterly, and semi-annual and annual withdrawals of
               $200, $400, $600 and $800, respectively.


        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 (for
Class B shares, annually; for Class A and Class C shares, during the first year
under the plan). Shareholders who elect to receive dividends in cash may not
participate in the 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), less
aggregate redemptions made other than pursuant to the plan, is less than the
minimum values specified above. Purchases of additional shares of a fund
concurrent with withdrawals are ordinarily disadvantageous to shareholders
because of tax liabilities and, for Class A shares, initial sales charges. On or
about the 20th of a month for monthly, quarterly, semi-annual and annual plans,
PaineWebber will arrange for redemption by the fund of sufficient fund shares to
provide the withdrawal payments specified by participants in the systematic
withdrawal plan. The payments generally are mailed approximately five Business
Days (defined under "Valuation of Shares") after the redemption date. Withdrawal
payments should not be considered dividends, but redemption proceeds. If
periodic withdrawals continually exceed reinvested dividends, 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 in which purchases of
PaineWebber mutual funds and other investments may be made are available through
PaineWebber. 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 PLAN'sm';
PAINEWEBBER RESOURCE MANAGEMENT ACCOUNT'r' (RMA)'r'

        Shares of PaineWebber mutual funds (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 to continually 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


                                       23




<PAGE>



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, de-emphasizing 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 both low
and high share 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:


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


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

               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.


               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.


               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;


                                       24




<PAGE>




               free and unlimited electronic funds transfers and bill payment
               service for $6 a month -- unlimited fixed and variable payments.


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


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


               automatic direct deposit of checks into your RMA account and
               automatic withdrawals from the account.

        The annual account fee for an RMA account is $85, which includes the
Gold MasterCard, with an additional fee of $40 if the investor selects an
optional line of credit with the Gold MasterCard.


                          CONVERSION OF CLASS B SHARES


        Class B shares will automatically convert to Class A shares, based on
the relative net asset values per share of the two classes, as of the close of
business on the first Business Day (as defined under "Valuation of Shares") of
the month in which the sixth anniversary of the initial issuance of such Class B
shares occurs. For the purpose of calculating the holding period required for
conversion of Class B shares, the date of initial issuance shall mean the date
of issuance of the original Class B shares of the PaineWebber mutual fund that
were exchanged (directly or through a series of exchanges) for the fund's Class
B shares. For purposes of conversion to Class A shares, Class B shares purchased
through the reinvestment of dividends and other distributions paid in respect of
Class B shares of the fund or of those other PaineWebber mutual funds are held
in a separate sub-account. Each time any Class B shares in the shareholder's
regular account (other than those in the sub-account) convert to Class A shares,
a pro rata portion of the Class B shares in the sub-account will also convert to
Class A shares. The portion will be determined by the ratio that the
shareholder's Class B shares converting to Class A shares bears to the
shareholder's total Class B shares not acquired through dividends and other
distributions.


        The conversion feature is subject to the continuing availability of an
opinion of counsel to the effect that the dividends and other distributions paid
on Class A and Class B shares will not result in "preferential dividends" under
the Internal Revenue Code and that the conversion of shares does not constitute
a taxable event. If the conversion feature ceased to be available, the Class B
shares would not be converted and would continue to be subject to the higher
ongoing expenses of the Class B shares beyond six years from the date of
purchase. Mitchell Hutchins has no reason to believe that this condition will
not continue to be met.


                                  VALUATION OF SHARES


               The fund determines its net asset value 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 ("NYSE") on each Business Day,
which is defined as each Monday through Friday when the NYSE is open. Net asset
value will be calculated earlier when the NYSE closes early because trading has
been halted for the day. Currently the NYSE is closed on the observance of the
following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day
and Christmas Day.



        The fund values its portfolio securities in accordance with the
amortized cost method of valuation under Rule 2a-7 ("Rule") under the Investment
Company Act. To use amortized cost to value its portfolio securities, the fund
must adhere to certain conditions under the Rule relating to its investments,
some of which are discussed in this SAI. Amortized cost is an approximation of
market value of an instrument, whereby the difference between its acquisition
cost and value at maturity is amortized on a straight-line basis over the
remaining life of the instrument. The effect of changes in the market value of a
security as a result of fluctuating interest rates is not taken into account,
and thus the amortized cost method of valuation may result in the value of a
security being higher or lower than its actual market value. If a large number
of redemptions take place at a time when interest



                                       25




<PAGE>



rates have increased, the fund might have to sell portfolio securities prior to
maturity and at a price that might not be desirable.

        The board has established procedures ("Procedures") for the purpose of
maintaining a constant net asset value of $1.00 per share, which include a
review of the extent of any deviation of net asset value per share, based on
available market quotations, from the $1.00 amortized cost per share. If that
deviation exceeds 1/2 of 1% for the fund, the board will promptly consider
whether any action should be initiated to eliminate or reduce material dilution
or other unfair results to shareholders. Such action may include redeeming
shares in kind, selling portfolio securities prior to maturity, reducing or
withholding dividends and utilizing a net asset value per share as determined by
using available market quotations. The fund will maintain a dollar-weighted
average portfolio maturity of 90 days or less and will not purchase any
instrument having, or deemed to have, a remaining maturity of more than 397
days, will limit portfolio investments, including repurchase agreements, to
those U.S. dollar-denominated instruments that are of high quality under the
Rule and that Mitchell Hutchins, acting pursuant to the Procedures, determines
present minimal credit risks, and will comply with certain reporting and
recordkeeping procedures. There is no assurance that constant net asset value
per share will be maintained. If amortized cost ceases to represent fair value
per share, the board will take appropriate action.


        In determining the approximate market value of portfolio investments,
the fund may employ outside organizations, which may use a matrix or formula
method that takes into consideration market indices, matrices, yield curves and
other specific adjustments. This may result in the securities being valued at a
price different from the price that would have been determined had the matrix or
formula method not been used. Other assets, if any, are valued at fair value as
determined in good faith by or under the direction of the board.



                                PERFORMANCE INFORMATION

        The fund's performance data quoted in advertising and other promotional
materials ("Performance Advertisements") represent past performance and are not
intended to indicate future performance. The investment return will fluctuate.

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


<TABLE>
<S>                  <C> <C>
     P(1 + T)'pp'n   =   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.
</TABLE>


        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 B and Class C
shares, the applicable contingent deferred sales charge imposed on a redemption
of Class B or Class C shares held for the period is deducted. All dividends 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. 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. Contingent deferred sales charges
are not taken into account in calculating Non-Standardized Return; the inclusion
of those charges would reduce the return.

        CALCULATION OF YIELD. The fund computes its yield and effective yield
quotations for each class of shares using standardized methods required by the
SEC. The fund from time to time advertises for each class of shares (1) its
current yield based on a recently ended seven-day period, computed by
determining the net change, exclusive of capital changes, in the value of a
hypothetical pre-existing account having a balance of one share at the beginning
of the period, subtracting a hypothetical charge reflecting deductions from that
shareholder account, dividing the difference by the value of the account at the
beginning of the base period to obtain the base period return, and then
multiplying the base period return by (365/7), with the resulting yield figure
carried to at least the nearest hundredth of one percent, and (2) its effective
yield based on the same seven-day period by compounding the base period return
by adding 1, raising the sum to a power equal to (365/7), and subtracting 1 from
the result, according to the following formula:


              EFFECTIVE YIELD = [(BASE PERIOD RETURN + 1)'pp'365/7] - 1

        For the seven days ended February 28, 1999, the yield and effective
yield of the fund's shares was as follows:

        Yield may fluctuate daily and does not provide a basis for determining
future yields. Because the yield of each class of shares of the fund fluctuates,
it cannot be compared with yields on savings accounts or other investment
alternatives that provide an agreed-to or guaranteed fixed yield for a stated
period of time. However, yield information may be useful to an investor
considering temporary investments in money market instruments. In comparing the
yield of one money market fund to another, consideration should be given to each
fund's investment policies, including the types of investments made, the average
maturity of the portfolio securities and whether there are any special account
charges that may reduce the yield.



        OTHER INFORMATION. The fund's performance data quoted in advertising and
other promotional materials ("Performance Advertisements") represent past
performance and are not intended to predict or indicate future results. The
return on an investment in the fund will fluctuate. In Performance
Advertisements, the fund may compare its yield with data published by Lipper
Analytical Services, Inc. for money funds ("Lipper"), CDA Investment
Technologies, Inc. ("CDA"), IBC Financial Data, Inc. ("IBC"), Wiesenberger
Investment Companies Service ("Wiesenberger") or Investment Company Data Inc.
("ICD"), or Morningstar Mutual Funds ("Morningstar") or with the performance of
recognized stock and other indexes, including the Standard & Poor's 500
Composite Stock Price Index, the Dow Jones Industrial Average, the Morgan
Stanley Capital International World Index, the Lehman Brothers Treasury Bond
Index, the Lehman Brothers Government/Corporate Bond Index, the Salomon Brothers
Government Bond Index 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, IBC, Wiesenberger or ICD.
Performance Advertisements also may refer to discussions of the Fund and
comparative mutual fund data and ratings reported in independent periodicals,
including 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 also compare its performance with the performance of bank
certificates of deposit ("CDs") as measured by the CDA Certificate of Deposit
Index and the Bank Rate Monitor National Index and the average of yields of CDs
of major banks published by Banxquotes'r' 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
vary depending on the financial institution offering the CD and prevailing
interest rates. Bank accounts are insured in whole or in part by an agency of
the U.S. government and may offer a fixed rate of return. Fund shares are not
insured or guaranteed by the U.S. government and returns thereon will fluctuate.
While the fund seeks to maintain a stable net asset value of $1.00 per share,
there can be no assurance that it will be able to do so.



        The fund may include discussions or illustrations of the effects of
compounding in Performance Advertisements. "Compounding" refers to the fact
that, if dividends on the fund investment are reinvested by being paid in
additional fund shares, any future income 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 had been paid in cash. The fund
may also make available to shareholders a daily accrual factor or "mil rate"
representing dividends accrued to shareholder accounts on a given day or days.
Certain shareholders may find that this information facilitates accounting or
recordkeeping.



                                      TAXES


        BACKUP WITHHOLDING. The fund is required to withhold 31% of all
dividends payable to individuals and certain other non-corporate shareholders
who do not provide the fund or PaineWebber with a correct taxpayer
identification number or who otherwise are subject to backup withholding.


        CONVERSION OF CLASS B SHARES. A shareholder will recognize no gain or
loss as a result of a conversion from Class B shares to Class A shares.


                                       28

        QUALIFICATION AS A REGULATED INVESTMENT COMPANY. 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 its investment company taxable income (consisting generally of net
investment income and net short-term capital gains, if any) and must meet
several additional requirements. Among these requirements are 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 and certain other income; (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 the
full amount of its taxable income for that year without being able to deduct the
distributions it makes to its shareholders and (b) the shareholders would treat
all those distributions 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


        CLASSES OF SHARES. A share of each class of the fund represents an
interest in the fund's investment portfolio and has similar rights, privileges
and preferences. Each class may differ with respect to distribution and/or
service fees, 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 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, B and C 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 Corporation may elect all its board members. The shares of the
fund will be voted together, 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 shares of each series
of the Corporation will be voted separately, except when an aggregate vote of
all the series is required by law.



        The fund does not hold annual meetings. Shareholders of record of no
less than two-thirds of the outstanding shares of the Corporation may remove a
board member 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 a board member at
the written request of holders of record of at least 10% of the outstanding
shares of the Corporation.


        CLASS-SPECIFIC EXPENSES. The fund may determine to allocate certain of
its expenses (in addition to service and distribution fees) to the specific
classes of its shares to which those expenses are attributable. For example,
Class B and Class C shares bear higher transfer agency fees per shareholder
account than those borne by Class A 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 in order 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.

        PRIOR NAMES.  Prior to November  10, 1995,  the Class C shares of the
fund were called "Class D" shares.

        CUSTODIAN AND RECORDKEEPING AGENT; TRANSFER AND DIVIDEND AGENT. State

Item 24.    PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT

      None.

Item 25.  INDEMNIFICATION

      Article Eleventh of the Articles of Incorporation provides that the
directors and officers of the Registrant shall not be liable to the Registrant
or to any of its stockholders for monetary damages to the maximum extent
permitted by applicable law. Article Eleventh also provides that any repeal or
modification of Article Eleventh or adoption, or modification of any other
provision of the Articles or By-Laws inconsistent with Article Eleventh shall
not adversely affect any limitation of liability of any director or officer of
the Registrant with respect to any act or failure to act which occurred prior to
such repeal, modification or adoption.

      Article Eleventh of the Articles of Incorporation and Section 10.01 of
Article X of the By-Laws provide that the Registrant shall indemnify and advance
expenses to its present and past directors, officers, employees and agents, and
any persons who are serving or have served at the request of the Registrant as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust, or enterprise, to the fullest extent permitted by law.

      Section 10.02 of Article X of the By-Laws further provides that the
Registrant may purchase and maintain insurance on behalf of any person who is or
was a director, officer or employee of the Registrant, or is or was serving at
the request of the Registrant as a director, officer or employee of a
corporation, partnership, joint venture, trust or other enterprise against any
liability asserted against him or out of his or her status as such whether or
not the Registrant would have the power to indemnify him or her against such
liability.

      Section 9 of the Investment Advisory and Administration Contract provides
that Mitchell Hutchins Asset Management Inc. ("Mitchell Hutchins") shall not be
liable for any error of judgment or mistake of law or for any loss suffered by
Registrant in connection with the matters to which the Contract relates except
for a loss resulting from 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 9 further
provides that any person, even though also an officer, partner, employee or
agent of Mitchell Hutchins, who may be or become an officer, director, employee
or agent of Registrant shall be deemed, when rendering services to the
Registrant or acting with respect to any business of the Registrant, to be
rendering such service to or acting solely for the Registrant and not as an
officer, partner, employee, or agent or one under the control or direction of
Mitchell Hutchins even though paid by it.

      Section 9 of each Distribution Contract provides that the Registrant will
indemnify Mitchell Hutchins and its officers, directors or controlling persons
against all liabilities arising from any alleged untrue statement of material
fact in the Registration Statement or from 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 Registrant 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 Registrant, its
officers and directors free and harmless of any claims arising out of any


                                      C-2



<PAGE>



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 each Distribution Contract.

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

      Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended, may be provided to directors, 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 director, 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 director, 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.

PaineWebber Master Series, Inc.
1285 Avenue of the Americas
New York, New York 10019

Ladies and Gentlemen:

      You have requested our opinion, as counsel to PaineWebber Master Series,
Inc. ("Fund"), as to certain matters regarding the issuance of certain Shares of
the Fund. As used in this letter, the term "Shares" means the Class A, Class B
and Class C shares of common stock of the series of the Fund listed below during
the time that Post-Effective Amendment No. 37 to the Fund's Registration
Statement on Form N-1A ("PEA") is effective and has not been superseded by
another post-effective amendment. This series of the Fund is PaineWebber Money
Market Fund.

      As such counsel, we have examined certified or other copies, believed by
us to be genuine, of the Fund's Articles of Incorporation and by-laws and such
resolutions and minutes of meetings of the Fund's Board of Directors as we have
deemed relevant to our opinion, as set forth herein. Our opinion is limited to
the laws and facts in existence on the date hereof, and it is further limited to
the laws (other than the conflict of law rules) in the State of Maryland that in
our experience are normally applicable to the issuance of shares by registered
investment companies organized as corporations under the laws of that State and
to the Securities Act of 1933 ("1933 Act"), the Investment Company Act of 1940
("1940 Act") and the regulations of the Securities and Exchange Commission
("SEC") thereunder.


      Based on the foregoing, we are of the opinion that the issuance of the
Shares has been duly authorized by the Fund and that, when sold in accordance
with the terms contemplated by the PEA, including receipt by the Fund of full
payment for the Shares and compliance with the 1933 Act and the 1940 Act, the
Shares will have been validly issued, fully paid and non-assessable.


      We hereby consent to this opinion accompanying the PEA when it is filed
with the SEC and to the reference to our firm in the statement of additional
information that is being filed as part of the PEA.


                                Very truly yours,

                                /s/ Kirkpatrick & Lockhart

                                KIRKPATRICK & LOCKHART LLP

CONSENT OF INDEPENDENT ACCOUNTANTS

We hereby consent to the incorporation by reference in the Prospectus and
Statement of Additional Information constituting parts of this Post-Effective
Amendment No. 37 to the registration statement on Form N-1A (the "Registration
Statement") of our report dated April 16, 1999, relating to the financial
