MONEY MARKET PORTFOLIO

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 and seeks to maintain a stable price of $1.00
per share. The fund invests in a diversified portfolio of high quality money
market instruments of governmental and private issuers.

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 may invest in any of these money market instruments. It invests in
foreign money market instruments only if they are denominated in U.S. dollars.

PaineWebber Incorporated, the fund's investment adviser, has appointed Mitchell
Hutchins Asset Management Inc. to serve as the fund's sub-adviser. Mitchell
Hutchins 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:

o Credit Risk

o Interest Rate Risk

o 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).

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

PRINCIPAL RISKS

The main risks of investing in one or more of the funds are described below. Not
all of these risks apply to each fund. You can find a list of the main risks
that apply to a particular fund by looking under the "Investment Objective,
Strategies and Risks" heading for that fund.

Other risks of investing in a fund, along with further detail about some of the
risks described below, are discussed in the funds' 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.

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.

INTEREST RATE RISK. The value of money market instruments generally can be
expected to fall when short-term interest rates rise and to rise when short-term
interest rates fall. Interest rate risk is the risk that interest rates will
rise, so that the value of a fund's investments will fall. Also, a fund's yield
will tend to lag behind changes in prevailing short-term interest rates. This
means that a fund's income will tend to rise more slowly than increases in
short-term interest rates. Similarly, when short-term interest rates are
falling, a fund's income will tend to fall more slowly. The value of a fund's
municipal money market instruments also could fall due to adverse political or
regulatory developments concerning tax exemptions for municipal securities.

RELATED SECURITIES CONCENTRATION RISK. Each of the municipal money market funds
may invest more than 25% of its total assets in municipal money market
instruments that are issued to finance similar projects, such as those relating
to education , health care, transportation or utilities. Economic, business or
political developments or changes that affect one municipal security may affect
municipal securities in the same sector. As a result, these funds are subject to
greater risk than funds that do not follow this practice.

SINGLE STATE CONCENTRATION RISK. The performance of a fund that invests
primarily in the municipal money market instruments of a single state will be
more severely affected by unfavorable political or economic conditions within
that state than a more geographically diversified fund. As a result, an
investment in the fund could be more volatile and involve greater risk than an
investment in a more geographically diversified fund. The particular risks of
investments in California, New York and New Jersey municipal money market
instruments are discussed in the SAI.

In addition, a single state municipal money market fund is permitted to invest
more than 5% of its total assets in the securities of a single issuer with
respect to 25% of its total assets. When a fund holds a large position in the
securities of a single issuer, changes in the financial condition or in the
market's assessment of that issuer can cause larger changes in the value of the
funds' total investments and its income that if the fund held only a smaller
position.

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 funds are subject to maturity, quality and
diversification requirements designed to help then maintain a stable price of

21
<PAGE>

PaineWebber RMA Funds
- ---------------------------------------------

$1.00 per share. The funds' investment strategies are designed to comply with
these requirements. RMA California, RMA New Jersey and RMA New York Municipal
Money Market Funds are organized as "non-diversified" funds. Normally, this
would mean that they would not be subject to certain limitations on investments
of more than 5% of total assets in the securities of a single issuer. However,
because these funds are single state money market funds, they are subject to
special regulations that impose substantially the same limitations as normally
apply to "diversified" mutual funds. The other funds are subject to even more
stringent diversification requirements, which apply to money market funds that
are not single state funds.

YOUR INVESTMENT

MANAGING YOUR FUND ACCOUNT
- --------------------------

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

You must be a PaineWebber client or a client of a PaineWebber correspondent firm
to purchase fund shares. Shares of the funds are available primarily through the
PaineWebber Resource Management Account (RMA(R)) Program. Shares of the funds
also are available to participants in the PaineWebber Business Services Account
(BSA(R)) Program

Certain features available to RMA and BSA participants are summarized in the
Appendices to the SAI. The RMA and BSA programs are more fully described in
separate materials your Financial Advisor can provide you. Not all correspondent
firms have arrangements with PaineWebber to make fund shares available to their
customers.

PaineWebber asks participants in these programs to select one of the funds as
their primary sweep money fund. You may have only one primary sweep money fund
at any time, but you may change your primary sweep money fund or purchase shares
of another fund by contacting your Financial Advisor.

Your order to purchase a fund's shares will be effective on the business day on
which federal funds become available to the fund. Federal funds are funds
deposited by a commercial bank in an account at a Federal Reserve Bank that can
be transferred to a similar account of another bank in one day and thus can be
made immediately available to the fund. A business day is any day that the
Boston offices of the fund's custodian and the New York City offices of
PaineWebber and its bank, The Bank of New York, are open for business.

Each fund (other than Money Market Portfolio) has adopted a plan under rule
12b-1 under which the fund pays fees for services provided to its shareholders
at the annual rate of 0.125% of its average net assets (0.12% for New Jersey
Municipal Money Fund).

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

BUYING SHARES AUTOMATICALLY

All free cash credit balances (that is, immediately available funds) of $1 or
more in your PaineWebber RMA or BSA brokerage account (including proceeds from
securities you have sold) are automatically invested in your primary sweep money
fund on a daily basis for settlement the next business day, when federal funds
normally are available. For cash balances arising from the sale of securities in
your brokerage account, federal funds availability can sometimes take longer.

Fund shares will be purchased only after all debits and charges to your RMA or
BSA brokerage account are satisfied. See "Selling Shares Automatically" below.

BUYING SHARES BY CHECK OR ELECTRONIC FUNDS TRANSFER CREDIT

RMA and BSA participants may purchase shares of their primary sweep money fund
or another fund by placing an order with their PaineWebber Financial Advisor and
providing a check from a U.S. bank. You should include your PaineWebber account
number on the check.

Federal funds are deemed available to a fund two business days after the deposit
of a personal check or an Electronic Funds Transfer credit initiated by

ADDITIONAL INFORMATION

It costs the fund money to maintain shareholder accounts. Therefore, each fund
reserves the right to repurchase all shares in any account that has a net asset
value of less than $500. If a 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. This notice may appear on your account statement.

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

PaineWebber has the right to terminate your RMA or BSA brokerage account for any
reason. In that case, PaineWebber will sell all of the fund shares held in the
RMA or BSA brokerage account and will send you the proceeds within three
business days.

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

The price of fund shares is based on net asset value. The net asset value is the
total value of a fund divided by the total number of shares outstanding. In

24
<PAGE>

PaineWebber RMA Funds
- ---------------------------------------------

determining net asset value, each 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.
Each fund's net asset value per share is expected to be $1.00 per share,
although this value is not guaranteed.

Each fund calculates net asset value once each business day at 12:00 noon,
Eastern time. Your price for buying or selling shares will be the net asset
value that is next calculated after the fund accepts your order. Your Financial
Advisor is responsible for making sure that your order is promptly sent to the
fund.

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

DIVIDENDS

The funds declare dividends daily and pay them monthly. The funds distribute any
net short-term capital gain annually, but may make more frequent distributions
if necessary to maintain their share prices at $1.00 per share.

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

TAXES

The dividends that you receive from the Money Market Portfolio and U.S.
Government Portfolio generally are subject to federal income tax regardless of
whether you receive them in additional fund shares or in cash. The funds expect
that their dividends will be taxed primarily as ordinary income. 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 dividends that you receive from Tax-Free Fund, California Municipal Money
Fund, New York Municipal Money Fund and New Jersey Municipal Money Fund
generally are not subject to federal income tax.

In addition, California Municipal Money Fund seeks to pay dividends that are
exempt from California personal income tax, New Jersey Municipal Money Fund

New York Municipal Money Fund seeks to pay dividends that are exempt from New
York State and New York City personal income tax.

Each fund will tell you how you should treat its dividends for tax purposes. You

fund maintains a share price of $1.00.

THE FUNDS AND THEIR INVESTMENT POLICIES

Each fund's investment objective may not be changed without shareholder
approval. Except where noted, the other investment policies of a fund may be
changed by its board without shareholder approval. As with other mutual funds,
there is no assurance that a fund will achieve its investment objective. Each
fund is a money market fund that invests in high quality money market
instruments that have, or are deemed to have, remaining maturities of 13 months
or less and maintains a dollar-weighted average portfolio maturity of 90 days or
less. 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. Each fund may purchase only those obligations that Mitchell
Hutchins determines, pursuant to procedures adopted by the board, present
minimal credit risks and are "First Tier Securities" as defined in Rule 2a-7
under the Investment Company Act of 1940, as amended ("Investment Company Act").

MONEY MARKET PORTFOLIO

Money Market Portfolio's investment objective is to provide maximum
current income consistent with liquidity and conservation of capital. The fund's
investments 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)
repurchase agreements regarding any of the foregoing and (5) investment company
securities.

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 deposits have a maturity of seven days or less.

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.
The fund 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.

U.S. GOVERNMENT PORTFOLIO

U.S. Government Portfolio's investment objective is to provide maximum
current income consistent with liquidity and the conservation of capital. The
fund invests in U.S. government securities. Under investment guidelines adopted
by its board, the fund currently invests only in securities, such as U.S.
Treasury bills and notes and Government National Mortgage Association
certificates, that are backed by the full faith and credit of the United States,
in repurchase agreements secured by such securities and in the securities of
other investment companies that invest only in these instruments.

The fund may invest up to 10% of its net assets in illiquid securities.
The fund 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. The fund may invest in the securities of other
investment companies.

2
<PAGE>

TAX-FREE FUND

Tax Free Fund's investment objective is to provide maximum current income
exempt from federal income tax consistent with liquidity and conservation of
capital. The fund invests substantially all of its assets in money market
instruments issued by states, municipalities, public authorities and other
issuers, the interest from which is exempt from federal income tax ("municipal
securities"). The fund also may purchase participation interests in municipal
securities. Participation interests are pro rata interests in securities held by
others.

Under normal market conditions, the fund intends to invest in municipal
securities that pay interest that is not an item of tax preference for purposes
of the federal alternative minimum tax ("AMT exempt interest"), but may invest
up to 20% of its total assets in such securities if in Mitchell Hutchins'
judgment, market conditions warrant.

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 invest up to 10% of its net assets in illiquid securities. The fund 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.

CALIFORNIA MUNICIPAL MONEY FUND

California Municipal Money Fund's investment objective is to provide
maximum current income exempt from federal income tax and California's personal
income tax consistent with liquidity and conservation of capital. The fund
invests at least 80% and seeks to invest 100% of its net assets in municipal
securities issued by the State of California, its municipalities and public
authorities and other issuers if such obligations pay interest that is exempt
from federal income tax as well as California personal income tax ("California
municipal securities"). The fund also may purchase participation interests in
California municipal securities. Participation interests are pro rata interests
in securities held by others.

Under normal market conditions, the fund intends to invest in California
municipal securities that pay AMT exempt interest, but may invest without limit
in securities that pay interest that is subject to the AMT if, in Mitchell
Hutchins' judgment, market conditions warrant.

As a single state money market fund, the fund may invest more than 5% of
its total assets in the securities of a single issuer with respect to 25% of its
total assets. The fund may invest up to 10% of its net assets in illiquid
securities. The fund 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. The fund may invest in the
securities of other investment companies.

NEW JERSEY MUNICIPAL MONEY FUND

New Jersey Municipal Money Fund's investment objective is the maximization
of current income exempt from federal income tax and New Jersey personal income
tax consistent with the preservation of capital and the maintenance of
liquidity. The fund invests at least 65% and seeks to invest 100% of its net
assets in municipal securities issued by the State of New Jersey, its
municipalities and public authorities and other issuers if such obligations pay
interest that is exempt from federal income tax as well as New Jersey personal
income tax ("New Jersey municipal securities"). The fund also may purchase
participation interests in New Jersey municipal securities. Participation
interests are pro rata interests in securities held by others. Under normal
market conditions, the fund will not invest more than 25% of its total assets in
participation interests or other securities issued by or purchased from banks or
other financial institutions.

The fund may invest without limit in New Jersey securities that pay
interest that is subject to the AMT.

securities of other investment companies.

NEW YORK MUNICIPAL MONEY FUND

New York Municipal Money Fund's investment objective is to provide maximum
current income exempt from federal income tax and New York State and New York
City personal income taxes consistent with liquidity and conservation of
capital. The fund invests at least 80% and seeks to invest 100% of its net
assets in municipal securities issued by the State of New York, its
municipalities and public authorities and other issuers if such obligations pay
interest that is exempt from federal income tax as well as New York State and

also may purchase participation interests in New York municipal securities.
Participation interests are pro rata interests in securities held by others.

Under normal market conditions, the fund intends to invest in New York
municipal securities that pay AMT exempt interest, but may invest without limit
in securities that pay interest that is subject to the AMT if, in Mitchell
Hutchins' judgment, market conditions warrant.

THE FUNDS' INVESTMENTS, RELATED RISKS AND LIMITATIONS

The following supplements the information contained in the Prospectus and
above concerning each fund's investments, related risks and limitations. Except
as otherwise indicated in the Prospectus or the Statement of Additional
Information, each fund has established no policy limitations on its ability to
use the investments or techniques discussed in these documents. New forms of
money market instruments continue to be developed. The funds may invest in these
instruments to the extent consistent with their investment objectives.

YIELDS AND CREDIT RATINGS OF MONEY MARKET INSTRUMENTS; FIRST TIER
SECURITIES. The yields on the money market instruments in which each fund
invests (such as U.S. government securities, commercial paper, bank obligations
and municipal securities) 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
nationally recognized statistical rating organizations ("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 a fund, an issue may cease to be rated or
its rating may be reduced. If a security in a fund's portfolio ceases to be a
First Tier Security 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, a fund's board, will consider whether a 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 in priority and security, (4) subject to a guarantee
rated in the highest short-term rating category or issued by a guarantor that

4
<PAGE>

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.

Money Market Portfolio and U.S. Government Portfolio may invest in
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. Money Market Portfolio
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 non-convertible debt obligations
subject to maturity constraints imposed by Rule 2a-7 under the Investment
Company Act.

ASSET-BACKED SECURITIES. [Money Market Portfolio] may invest in securities
that are comprised of financial assets. Such assets may include a motor vehicle
and other types of 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 Funds'
Investments, Related Risks and Limitations -- Credit and Liquidity
Enhancements."

VARIABLE AND FLOATING RATE SECURITIES AND DEMAND INSTRUMENTS. Money Market
Portfolio and U.S. Government Portfolio 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, Money Market Portfolio may purchase variable and floating rate
securities of other issuers and the municipal funds may purchase such securities
of municipal issuers including tender option bonds. The funds will only purchase
these other types of variable and floating rate securities 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. Each 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 a fund the right to tender them back to a specified
party, usually the issuer or a remarketing agent, prior to maturity. See "The
Funds' Investments, Related Risks and Limitations -- Credit and Liquidity
Enhancements."

Generally, each 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 a 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

5
<PAGE>

value of floating rate and variable rate securities to fluctuate less than the
market value of fixed rate securities.

VARIABLE AMOUNT MASTER DEMAND NOTES. Money Market Portfolio 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. Money Market Portfolio'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 in the credit quality of these financial institutions could cause losses
to the fund and affect its share price. The credit and liquidity enhancements
may have conditions that limit the ability of the fund to use them when the fund
wished to do so.

TENDER OPTION BONDS. The Municipal Funds may invest in "tender option
bonds." Tender option bonds are long-term municipal securities sold by a bank or
other financial institution subject to a demand feature that gives the purchaser
the right to sell them to the bank or other financial institution at par plus
accrued interest at designated times (the "tender option"). The Municipal Funds
may invest in bonds with tender option that may be exercisable at intervals
ranging from daily to 397 days, and the interest rate on the bonds is typically
reset at the end of the applicable interval in an attempt to cause the bonds to
have a market value that approximates their par value. The tender option may not
be exercisable in the event of a default on, or significant downgrading of, the
underlying municipal securities, and may be subject to other conditions.
Therefore, a Fund's ability to exercise the tender option will be affected by
the credit standing of both the bank or other financial institution involved and
the issuer of the underlying securities.

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 a fund
has valued the securities and includes, among other things, repurchase
agreements maturing in more than seven days, restricted securities and municipal
lease obligations (including certificates of participation) other than those
Mitchell Hutchins has determined are liquid pursuant to guidelines established
by each fund's board. To the extent the funds invest in illiquid securities,
they 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, a 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 a fund
may be permitted to sell a security under an effective registration statement.
If, during such a period, adverse market conditions were to develop, a 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

6
<PAGE>

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
a 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.

Each 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, which may include (1) the frequency of trades for the security, (2)
the number of dealers that make quotes, or are expected to 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 each fund's portfolio and reports periodically on such decisions to the
applicable board.

REPURCHASE AGREEMENTS. Money Market Portfolio and U.S. Government
Portfolio each may enter into repurchase agreements with respect to any security
in which it is authorized to invest, except that securities subject to
repurchase agreements may have maturities in excess of 13 months. Each municipal
fund may enter into repurchase agreements with respect to U.S. government
securities, commercial paper, bank certificates of deposit and bankers'
acceptances. Repurchase agreements are transactions in which a 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.
Securities or other obligations subject to repurchase agreements may have
maturities in excess of 13 months. A 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 difference between the total amount to be received upon
repurchase of the obligations and the price that was paid by a 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,
a fund may suffer delays, costs and possible losses in connection with the
disposition of collateral. Each 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 a 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 a fund's
limitation on borrowings and may be entered into only with banks and securities
dealers. While a reverse repurchase agreement is outstanding, a 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 Funds' Investments and Related Risks--
Segregated Accounts."

Reverse repurchase agreements involve the risk that the buyer of the
securities sold by a fund might be unable to deliver them when the fund seeks to
repurchase. If the buyer of securities under a reverse repurchase agreement

7
<PAGE>

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 a fund's use of the proceeds of the
reverse repurchase agreement may effectively be restricted pending such
decision.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. Each 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. A
fund generally would not pay for such securities or start earning interest on
them until they are received. However, when a 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 a fund on a when-issued or delayed delivery basis may
result in a 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 a fund's net asset value. When a 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 Funds' Investments and Related
Risks--Segregated Accounts." Each 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. Each Municipal Fund expects that
commitments to purchase when-issued or delayed delivery securities will not
exceed 25% of its assets (20% in the case of New Jersey Municipal Money Fund).

INVESTMENTS IN OTHER INVESTMENT COMPANIES. Each 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, a fund would continue to pay its own management fees and expenses
with respect to all its investments, including shares of other money market
funds. Each 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. Each fund is authorized to lend its
portfolio securities to broker-dealers or institutional investors that Mitchell
Hutchins deems qualified. Lending securities enables a fund to earn additional
income, but could result in a loss or delay in recovering these securities. The
borrower of a fund's portfolio securities must maintain acceptable collateral
with the fund's custodian in an amount, marked to market daily, at least equal
to the market value of the securities loaned, plus accrued interest and
dividends. Acceptable collateral is limited to cash, U.S. government securities
and irrevocable letters of credit that meet certain guidelines established by
Mitchell Hutchins. Each 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. Each fund will retain authority to terminate any of its loans at any
time. Each 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. Each fund will receive amounts
equivalent to any interest, dividends or other distributions on the securities
loaned. Each 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 a fund's interest.

Pursuant to procedures adopted by the board of each fund governing a
fund's securities lending program, PaineWebber has been retained to serve as
lending agent for a fund. The board of each fund 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 a 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 a fund's obligation or commitment under such
transactions

CERTAIN POLICIES OF THE MUNICIPAL FUNDS

Tax-Free Fund, California Municipal Money Fund, New Jersey Municipal Money
Fund and New York Municipal Money Fund may be referred to collectively as the
"municipal funds."

NON-DIVERSIFIED STATUS OF SINGLE STATE MUNICIPAL FUNDS. California
Municipal Money Fund, New Jersey Municipal Money Fund and New York Municipal
Money Fund are "non-diversified funds," as that term is defined in the
Investment Company Act. In general, a non-diversified fund is not subject to
certain limitations on its ability to invest more than 5% of its total assets in
securities of a single issuer with respect to 50% of its assets. Rule 2a-7 under
the Investment Company Act, however, imposes more stringent diversification
requirements on money market funds. For single state municipal money market
funds, Rule 2a-7 generally requires that the securities of a single issuer may
not exceed 5% of the fund's total assets with respect to at least 75% of its
assets. Nonetheless, a single state municipal money fund may be subject to
greater risk than a money market fund that is more "diversified" because changes
in the financial condition of a single issuer may cause greater fluctuations in
its yield or on its ability to maintain a constant net asset value per share.

TYPES OF MUNICIPAL SECURITIES. Each municipal fund may invest in a variety
of municipal securities, as described below:

MUNICIPAL BONDS. Municipal bonds are debt obligations that are issued by
states, municipalities, public authorities or other issuers and that pay
interest that is exempt from federal income tax in the opinion of issuer's
counsel. The two principal classifications of municipal bonds are "general
obligation" and "revenue" bonds. General obligation bonds are secured by the
issuer's pledge of its full faith, credit and taxing power for the payment of
principal and interest. Revenue bonds are payable only from the revenues derived
from a particular facility or class of facilities or, in some cases, from the
proceeds of a special excise tax or other specific revenue source such as from
the user of the facility being financed. The term "municipal bonds" also
includes "moral obligation" issues, which are normally issued by special purpose
authorities. In the case of such issues, an express or implied "moral
obligation" of a related government unit is pledged to the payment of the debt
service, but is usually subject to annual budget appropriations. Custodial
receipts that represent an ownership interest in one or more municipal bonds
also are considered to be municipal bonds. Various types of municipal bonds are
described in the following sections.

MUNICIPAL LEASE OBLIGATIONS. Municipal bonds include municipal lease
obligations, such as leases, installment purchase contracts and conditional
sales contracts, and certificates of participation therein. Municipal lease
obligations are issued by state and local governments and authorities to
purchase land or various types of equipment or facilities and may be subject to
annual budget appropriations. The funds generally invest in municipal lease
obligations through certificates of participation.

Although municipal lease obligations do not constitute general obligations
of the municipality for which the municipality's taxing power is pledged, they
ordinarily are backed by the municipality's covenant to budget for, appropriate
and make the payments due under the lease obligation. The leases underlying
certain municipal lease obligations, however, provide that lease payments are
subject to partial or full abatement if, because of material damage or
destruction of the leased property, there is substantial interference with the
lessee's use or occupancy of such property. This "abatement risk" may be reduced
by the existence of insurance covering the leased property, the maintenance by
the lessee of reserve funds or the provision of credit enhancements such as
letters of credit.

Certain municipal lease obligations contain "non-appropriation" clauses
which provide that the municipality has no obligation to make lease or
installment purchase payments in future years unless money is appropriated for

9
<PAGE>

such purpose on a yearly basis. Some municipal lease obligations of this type
are insured as to timely payment of principal and interest, even in the event of
a failure by the municipality to appropriate sufficient funds to make payments
under the lease. However, in the case of an uninsured municipal lease
obligation, a fund's ability to recover under the lease in the event of a
non-appropriation or default will be limited solely to the repossession of
leased property without recourse to the general credit of the lessee, and
disposition of the property in the event of foreclosure might prove difficult.

INDUSTRIAL DEVELOPMENT BONDS ("IDBS") AND PRIVATE ACTIVITY BONDS ("PABS").
IDBs and PABs are are issued by or on behalf of public authorities to finance
various privately operated facilities, such as airport or pollution control
facilities. These obligations are considered municipal bonds if the interest
paid thereon is exempt from federal income tax in the opinion of the bond
issuer's counsel. IDBs and PABs are in most cases revenue bonds and thus are not
payable from the unrestricted revenues of the issuer. The credit quality of IDBs
and PABs is usually directly related to the credit standing of the user of the
facilities being financed. IDBs issued after August 15, 1986 generally are
considered PABs, and to the extent a fund invests in such PABs, shareholders
generally will be required to include a portion of their exempt-interest
dividends from that fund in calculating their liability for the AMT. See "Taxes"
below. Each municipal fund may invest more than 25% of its net assets in IDBs
and PABs.

PARTICIPATION INTERESTS. Participation interests are interests in
municipal bonds, including IDBs, PABs and floating and variable rate
obligations, that are owned by banks. These interests carry a demand feature
permitting the holder to tender them back to the bank, which demand feature
generally is backed by an irrevocable letter of credit or guarantee of the bank.
The credit standing of such bank affects the credit quality of the participation
interests.

A participation interest gives a fund an undivided interest in a municipal
bond owned by a bank. The fund has the right to sell the instruments back to the
bank. As discussed above under "The Funds' Investments, Related Risks and
Limitations -- Credit and Liquidity Enhancements," to the extent that payment of
an obligation is backed by a letter of credit, guarantee or liquidity support
arrangement from a bank or other financial institution, such payment may be
subject to the financial institution's ability to satisfy that commitment.
Mitchell Hutchins will monitor the pricing, quality and liquidity of the
participation interests held by a fund, and the credit standing of banks issuing
letters of credit or guarantees supporting such participation interests on the
basis of published financial information reports of rating services and bank
analytical services.

PUT BONDS. A put bond is a municipal bond that gives the holder the
unconditional right to sell the bond back to the issuer or a remarketing agent
at a specified price and exercise date, which is typically well in advance of
the bond's maturity date. The obligation to purchase the bond on the exercise
date may be supported by a letter of credit or other credit support arrangement
from a bank, insurance company or other financial institution, the credit
standing of which affects the credit quality of the obligation.

If the put is a "one time only" put, the fund ordinarily will either sell
the bond or put the bond, depending upon the more favorable price. If the bond
has a series of puts after the first put, the bond will be held as long as, in
the judgment of Mitchell Hutchins, it is in the best interest of the fund to do
so. There is no assurance that the issuer of a put bond acquired by a fund will
be able to repurchase the bond upon the exercise date, if the fund chooses to
exercise its right to put the bond back to the issuer.

TAX-EXEMPT COMMERCIAL PAPER AND SHORT-TERM MUNICIPAL NOTES. Municipal
bonds include tax-exempt commercial paper and short-term municipal notes, such
as tax anticipation notes, bond anticipation notes, revenue anticipation notes
and other forms of short-term loans. Such notes are issued with a short-term
maturity in anticipation of the receipt of tax funds, the proceeds of bond
placements and other revenues.

MORTGAGE SUBSIDY BONDS. The funds also may purchase mortgage subsidy bonds
with a remaining maturity of less than 13 months that are issued to subsidize
mortgages on single family homes and "moral obligation" bonds with a remaining
maturity of less than 13 months that are normally issued by special purpose
public authorities. In some cases the repayment of such bonds depends upon
annual legislative appropriations; in other cases repayment is a legal

10
<PAGE>

obligation of the issuer, and if the issuer is unable to meet its obligations,
repayment becomes a moral commitment of a related government unit (subject,
however, to such appropriations).

STAND-BY COMMITMENTS. A municipal fund may acquire stand-by commitments
under unusual market conditions to facilitate portfolio liquidity. Pursuant to a
stand-by commitment, a municipal bond dealer agrees to purchase the securities
that are the subject of the commitment at an amount equal to (1) the acquisition
cost (excluding any accrued interest paid on acquisition), less any amortized
market premium and plus any accrued market or original issue discount, plus (2)
all interest accrued on the securities since the last interest payment date or
the date the securities were purchased, whichever is later.

A fund will enter into stand-by commitments only with those banks or other
dealers that, in the opinion of Mitchell Hutchins, present minimal credit risk.
A fund's right to exercise stand-by commitments will be unconditional and
unqualified. Stand-by commitments will not be transferable by a fund, although a
fund may sell the underlying securities to a third party at any time. A fund may
pay for stand-by commitments either separately in cash or by paying a higher
price for the securities that are acquired subject to such a commitment (thus
reducing the yield to maturity otherwise available for the same securities). The
acquisition of a stand-by commitment will not ordinarily affect the valuation or
maturity of the underlying municipal securities. Stand-by commitments acquired
by a fund will be valued at zero in determining net asset value. Whether a fund
paid directly or indirectly for a stand-by commitment, its cost will be treated
as unrealized depreciation and will be amortized over the period the commitment
is held by the fund.

INVESTMENT LIMITATIONS

FUNDAMENTAL LIMITATIONS. The following investment limitations cannot be
changed with respect to a fund without the affirmative vote of the lesser of (1)
more than 50% of the outstanding shares of the fund or (2) 67% or more of the
shares 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, a later
increase or decrease in percentage resulting from changing values of portfolio
securities or amount of total assets will not be considered a violation of any
of the following limitations.

Each 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 limitation (a): With respect to this limitation, domestic and
foreign banking will be considered to be different industries: and (b)

11
<PAGE>

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 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 a part of, this
fundamental restriction: The fund's investments in master notes 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.

Money Market Portfolio, U.S. Government Portfolio and Tax-Free Fund will
not:

(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.

With respect to Money Market Portfolio and U.S. Government Portfolio, the
following interpretation applies to, but is not a part of, fundamental
limitation (7): 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.

With respect to Tax-Free Fund, the following interpretation applies to,
but is not a part of, fundamental limitation (7): Each state, territory and
possession of the United States (including the District of Columbia and Puerto
Rico), each political subdivision, agency, instrumentality and authority
thereof, and each multi-state agency of which a state is a member is a separate
"issuer." When the assets and revenues of an agency, authority, instrumentality
or other political subdivision are separate from the government creating the
subdivision and the security is backed only by the assets and revenues of the
subdivision, such subdivision would be deemed to be the sole issuer. Similarly,
in the case of an IDB or PAB, if that bond is backed only by the assets and
revenues of the non-governmental user, then that non-governmental user would be
deemed to be the sole issuer. However, if the creating government or another

12
<PAGE>

entity guarantees a security, then to the extent that the value of all
securities issued or guaranteed by that government or entity and owned by the
fund exceeds 10% of the fund's total assets, the guarantee would be considered a
separate security and would be treated as issued by that government or entity.

NON-FUNDAMENTAL LIMITATIONS. The following investment restrictions are not
fundamental and may be changed by each board without shareholder approval.

Each fund will not:

(1) 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.

(2) 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.

(3) 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.

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

(5) invest more than 10% of its net assets in illiquid securities.

ORGANIZATION OF THE FUNDS; DIRECTORS/TRUSTEES AND OFFICERS
AND PRINCIPAL HOLDERS OF SECURITIES

PaineWebber RMA Money Fund, Inc. and PaineWebber RMA Tax-Free Fund, Inc.
(each may be referred to as the "Corporation") were organized on July 2, 1982 as
Maryland corporations. Money Fund has three operating series and has authority

billion shares are designated as shares of Money Market Portfolio and $10
billion are designated as shares of U.S. Government Portfolio). Tax-Free Fund
has authority to issue 20 billion shares of common stock, par value $0.001 per
share. PaineWebber Managed Municipal Trust and PaineWebber Municipal Money
Market Series (each may be referred to as the "Trust") were formed on November
21, 1986 and September 14, 1990, respectively, as business trusts under the laws

and costs of shareholders meetings, the board and any committees thereof, (17)

Under the PaineWebber and Mitchell Hutchins Contracts (collectively,
"Contracts"), PaineWebber or Mitchell Hutchins will not be liable for any error
of judgment or mistake of law or for any loss suffered by a fund in connection
with the performance of the Contracts, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of PaineWebber or
Mitchell Hutchins in the performance of its duties or from reckless disregard of
its duties and obligations thereunder.

The Contracts are terminable with respect to each fund at any time without
penalty by vote of the applicable board or by vote of the holders of a majority
of the outstanding voting securities of that fund on 60 days' written notice to
PaineWebber or Mitchell Hutchins, as the case may be. The PaineWebber Contracts
are also terminable without penalty by PaineWebber on 60 days' written notice to
the appropriate Corporation or Trust, and the Mitchell Hutchins Contracts are
terminable without penalty by PaineWebber or Mitchell Hutchins on 60 days'
written notice to the other party. The Contracts terminate automatically upon
their assignment, and each Mitchell Hutchins Contract also terminates
automatically upon the assignment of the applicable PaineWebber Contract.

The following table shows the approximate net assets as of July 31, 1999,
sorted by category of investment objective, of the investment companies as to
which Mitchell Hutchins serves as adviser or sub-adviser. An investment company

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 the PaineWebber mutual 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 the PaineWebber mutual funds and
other Mitchell Hutchins advisory clients.

DISTRIBUTION ARRANGEMENTS. PaineWebber acts as distributor of shares of
the funds under separate distribution contracts with each Corporation or Trust
("Distribution Contracts") which require PaineWebber to use its best efforts,
consistent with its other business, to sell shares of the funds. Shares of the
funds are offered continuously. Payments by each fund (other than Money Market
Portfolio) to compensate PaineWebber for certain expenses incurred in connection
with its activities in providing certain shareholder and account maintenance
services are authorized under the Distribution Contracts and made in accordance
with related plans of distribution ("Plans") adopted by each Corporation or
Trust with respect to those funds in the manner prescribed by Rule 12b-1 under
the 1940 Act. No such payments have been authorized for Money Market Portfolio.

Under plans of distribution adopted for each of these funds in the manner
prescribed by Rule 12b-1 under the Investment Company Act ("Plan"), the fund
pays PaineWebber a service fee, accrued daily and payable monthly, for providing
certain shareholder and account maintenance services. Each fund's Plan (other
than the Plan for New Jersey Municipal Money Fund) authorizes it to pay
PaineWebber a service fee, computed daily and paid monthly, at an annual rate of
up to 0.15% of its average daily net assets. Each of these funds currently pays
service fees to PaineWebber at the annual rate of 0.125% of average net assets.
Any increase from 0.125% annual rate would require prior approval of the board.
Under its Plan, New Jersey Municipal Money Fund pays service fees to PaineWebber
at the annual rate of 0.12% of average net assets.

PaineWebber uses the 12b-1 service fees to pay PaineWebber Financial
Advisors and correspondent firms for shareholder servicing. The fee is also used
to offset PaineWebber's other 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.

Among other things, each Plan provides that (1) PaineWebber 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 or Trust and who have no direct or indirect financial interest
in the operation of the Plan or any agreement related to the Plan, acting in
person at a meeting called for that purpose, (3) payments by a Fund under the
Plan shall not be materially increased without the affirmative vote of the
holders of a majority of the affected Fund's outstanding shares and (4) while
the Plan remains in effect, the selection and nomination of board members who
are not "interested persons" of the Corporation or Trust shall be committed to
the discretion of the board members who are not "interested persons" of the
Corporation or Trust.

Under the applicable Plan, U.S. Government Portfolio, Tax-Free Fund,
California Municipal Money Fund and New York Municipal Money Fund each is
authorized to pay PaineWebber a service fee, computed daily and paid monthly, at
the annual rate of up to 0.15% of its average daily net assets. Each of these
funds currently pays service fees to PaineWebber at the annual rate of 0.125% of
average daily net assets. Any increase from the current annual rate would
require prior approval of the board. Under the applicable Plan, New Jersey
Municipal Money fund pays service fees to PaineWebber at an annual rate of 0.12%
of its average daily net assets.

The funds paid (or accrued) the following service fees to PaineWebber
under the Plans during the fiscal year ended June 30, 1999:

U.S. Government Portfolio
Tax-Free Fund
California Municipal Money Fund
New Jersey Municipal Money Fund
New York Municipal Money Fund

PaineWebber estimates that it incurred the following shareholder
service-related expenses with respect to each fund during the fiscal year ended
June 30 1999:

SERVICE FEES PAID TO
PAINEWEBBER
FINANCIAL ADVISORS ALLOCATED COSTS
U.S. Government Portfolio
Tax-Free Fund
California Municipal Money Fund
New Jersey Municipal Money Fund
New York Municipal Money Fund

"Allocated costs" include various internal costs allocated by PaineWebber
to its efforts at providing certain shareholder and account maintenance
services. These internal costs encompass office rent, salaries and other
overhead expenses of various PaineWebber departments and areas of operations.

25
<PAGE>

In approving the continuance of the Plan for a fund, the applicable board
considered all features of the distribution system for the fund, including (a)
PaineWebber's view that the payment of service fees at the annual rate of 0.02%
of the average daily net assets of the fund held in shareholder accounts
serviced by PaineWebber Financial advisors and correspondent firms was
attractive to such Financial Advisors and correspondent firms and would result
in greater growth of the fund than might otherwise be the case, (b) the extent
to which fund shareholders might benefit from economies of scale resulting from
growth in the fund's assets and shareholder account size and the potential for
continued growth, (c) the services provided to the fund and its shareholders by
PaineWebber pursuant to the applicable Distribution Contract, (d) PaineWebber's
expenses and costs under the Plan as described above and (e) the fact that the
expense of the Plan to funds with breakpoints in their advisory and
administration fees could be offset if the Plan is successful by the lower fee
rates that may be triggered as assets reach higher levels.

With respect to each Plan, the applicable board considered the benefits
that would accrue to PaineWebber under the Plan in that PaineWebber would
receive service 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 is
successful and the fund attains and maintains increased asset levels.

PORTFOLIO TRANSACTIONS

The funds purchase 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 Mitchell Hutchins Contracts authorize Mitchell Hutchins (with the
approval of the applicable board) to select brokers and dealers to execute
purchases and sales of each fund's portfolio securities. The Mitchell Hutchins
Contracts direct Mitchell Hutchins to use its best efforts to obtain the best
available price and most favorable execution with respect to all transactions
for the funds. [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 funds 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 if no weight
was attributed to the services 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 a fund
effects securities transactions may be used by Mitchell Hutchins in advising
other funds or accounts 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 Mitchell Hutchins Contracts. During its
past three fiscal years, no fund has paid any brokerage commissions; therefore,
none has allocated any brokerage transactions for research, analysis, advice and
similar services.

[Mitchell Hutchins may engage in agency transactions in over-the-counter
equity and debt 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

Investment decisions for each 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 a 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.

HOLDINGS OF REGULAR BROKER-DEALERS

As of June 30, 1999, Money Market Portfolio owned commercial paper and
other short-term obligations issued by the following persons who are regular
broker-dealers for the fund:

[information to be supplied]

ADDITIONAL INFORMATION REGARDING REDEMPTIONS

Each 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 a fund to dispose of securities owned by it or to determine
fairly the market value of its assets or (3) as the SEC may otherwise permit.
The redemption price may be more or less than the shareholder's cost, depending
on the market value of the fund's portfolio at the time, although each fund
attempts to maintain a constant net asset value of $1.00 per share.

If conditions exist that make cash payments undesirable, California
Municipal Money Fund and New York Municipal Money Fund each reserve the right to
honor any request for redemption by making payment in whole or in part in
securities chosen by the fund and valued in the same way as they would be valued
for purposes of computing the fund's net asset value. If payment is made in
securities, a shareholder may incur brokerage expenses in converting these
securities into cash. Managed Municipal Trust has elected, however, to be
governed by Rule 18f-1 under the 1940 Act, under which it is obligated to redeem
shares solely in cash up to the lesser of $250,000 or 1% of the net asset value
of a fund during any 90-day period for one shareholder. This election is
irrevocable unless the SEC permits its withdrawal.

Under normal circumstances, a fund will redeem shares when so requested by
a shareholder's broker-dealer other than PaineWebber by telegram or telephone to
PaineWebber. Such a redemption order will be executed at the net asset value
next determined after the order is received by PaineWebber. Redemptions of fund
shares effected through a broker-dealer other than PaineWebber may be subject to
a service charge by that broker-dealer.

VALUATION OF SHARES

Each fund uses its best efforts to maintain its net asset value at $1.00
per share. Each fund's net asset value per share is determined by State Street
Bank and Trust Company ("State Street") as of 12:00 noon, Eastern time, on each
Business Day. As defined in the Prospectus, "Business Day" means any day on
which State Street's Boston offices and the New York City offices of PaineWebber
and PaineWebber's bank, The Bank of New York, are all open for business. One or
more of these institutions will be closed on the observance of the following
holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good
Friday, Patriot's Day, Memorial Day, Independence Day, Labor Day, Columbus Day,
Veterans' Day, Thanksgiving Day and Christmas Day.

Each fund values its portfolio securities in accordance with the amortized
cost method of valuation under Rule 2a-7 ("Rule") under 1940 Act. To use
amortized cost to value its portfolio securities, a fund must adhere to certain

27
<PAGE>

conditions under the Rule relating to the fund's investments, some of which are
discussed in the Prospectus and this SAI. Amortized cost is an approximation of
market value, whereby the difference between acquisition cost and value at
maturity of the instrument 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 rates have increased, a fund
might have to sell portfolio securities prior to maturity and at a price that
might not be desirable.

Each board has established 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 any fund, its 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. Each fund will maintain a dollar-weighted average
portfolio maturity of 90 days or less and except as otherwise indicated herein
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 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, the relevant board will take appropriate action.

In determining the approximate market value of portfolio investments, each
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 applicable board.

PERFORMANCE INFORMATION

The funds' 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 each fund's Performance Advertisements are
calculated according to the following formula:

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

Under the foregoing formula, the time periods used in Performance
Advertisements will be based on rolling calendar quarters, updated to the last
day of the most recent quarter prior to submission of the advertisement for
publication. Total return, or "T" in the formula above, is computed by finding
the average annual change in the value of an initial $1,000 investment over the
period. All dividends are assumed to have been reinvested at net asset value.

The funds 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 funds calculate Non-Standardized Return
for specified periods of time by assuming an investment of $1,000 in fund shares

28
<PAGE>

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.

The following tables show performance information for the funds' shares
outstanding for the periods indicated. All returns for periods of more than one
year are expressed as an average annual return.

YIELD. Each fund computes its yield and effective yield quotations using
standardized methods required by the SEC. Each fund from time to time advertises
(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)365/7] - 1

29
<PAGE>

Each municipal fund from time to time also advertises its tax-equivalent
yield and tax-equivalent effective yield, also based on a recently ended
seven-day period. These quotations are calculated by dividing that portion of
the fund's yield (or effective yield, as the case may be) that is tax-exempt by
1 minus a stated income tax rate and adding the product to that portion, if any,
of the fund's yield that is not tax-exempt, according to the following formula:

E
-------
TAX-EQUIVALENT YIELD = (1-p ) + 1
E = Tax exempt yield
p = stated income tax rate
t = taxable yield

Yield may fluctuate daily and does not provide a basis for determining
future yields. Because the yield of each 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 funds' 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 each fund will fluctuate. In Performance
Advertisements, the funds may compare their standardized or non-standardized
return and taxable or tax-free yields with data published by Lipper Analytical

30
<PAGE>

Services, Inc. for money funds ("Lipper"), CDA Investment Technologies, Inc.
("CDA"), IBC/ Donoghue's Money Market Fund Report ("Donoghue"), Wiesenberger
Investment Companies Service ("Wiesenberger"), 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 Merrill Lynch
Municipal Bond Indices, the Morgan Stanley Capital World Index, the Lehman
Brothers Treasury Bond Index, the Lehman Brothers Government-Corporate Bond
Index, the Salomon Brothers Government Bond Index and the Consumer Price Index
as published by the U.S. Department of Commerce. The Funds 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, Donoghue,
Wiesenberger, ICD or Morningstar. Performance Advertisements also may refer to
discussions of the Funds 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.

Each fund may include discussions or illustrations of the effects of
compounding in Performance Advertisements. "Compounding" refers to the fact
that, if dividends on a 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 a fund investment would
increase more quickly than if dividends had been paid in cash.

Each fund may also compare its performance with the performances of bank
certificates of deposit ("CDs") as measured by the CDA Certificate of Deposit
Index and the Bank Rate Monitor National Index and the averages of yields of CDs
of major banks published by Banxquotes-Registered Trademark- Money Markets. In
comparing a 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. Advertisements and other promotional materials
for the funds or for the PaineWebber Resource Management Account(R) ("RMA") and
Business Services Accountsm ("BSA") programs may compare features of the RMA and
BSA programs to those offered by bank checking accounts and other bank accounts.
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
each 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.

TAXES

BACKUP WITHHOLDING. Each fund is required to withhold 31% of all
taxable dividends payable to individuals and certain other non-corporate
shareholders who (1) do not provide the fund or PaineWebber with a correct
taxpayer identification number on Form W-9 (for U.S. citizens and resident
aliens) or a properly completed claim for exemption on form W-8 (for nonresident
aliens and other foreigners) or (2) otherwise are subject to backup withholding.

QUALIFICATION AS A REGULATED INVESTMENT COMPANY. To continue to qualify
for treatment as a regulated investment company ("RIC") under the Internal
Revenue Code, each fund must distribute to its shareholders for each taxable
year at least 90% of its investment company taxable income (consisting generally
of taxable net investment income and net short-term capital gain, if any) plus,
in the case of each municipal fund, its net interest income excludable from
gross income under section 103(a) of the Internal Revenue Code, and must meet
several additional requirements. With respect to each fund, these requirements
include the following: (1) the fund must derive at least 90% of its gross income
each taxable year from dividends, interest, payments with respect to securities
loans, 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 and other securities, with these other securities
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) of any one
issuer.

31
<PAGE>

Dividends paid by a municipal fund will qualify as "exempt-interest
dividends," and thus will be excludable from gross income by its shareholders,
if it satisfies the additional requirement that, at the close of each quarter of
its taxable year, at least 50% of the value of its total assets consists of
securities the interest on which is excludable from gross income under section
103(a). Each municipal fund intends to continue to satisfy this requirement. The
aggregate amount annually designated by a municipal fund as exempt-interest
dividends may not exceed its interest for the year that is excludable under
section 103(a) over certain amounts disallowed as deductions. The shareholders'
treatment of dividends from the municipal funds under state and local income tax
laws may differ from the treatment thereof under the Internal Revenue Code.

Tax-exempt interest attributable to certain PABs (including, in the case
of a municipal fund receiving interest on such bonds, a proportionate part of
the exempt-interest dividends paid by that fund) is subject to the federal
alternative minimum tax. Exempt-interest dividends received by a corporate
shareholder also may be indirectly subject to that tax without regard to whether
a municipal fund's tax-exempt interest was attributable to those bonds. PABs are
issued by or on behalf of public authorities to finance various privately
operated facilities and are described in the Prospectus.

Entities or persons who are "substantial users" (or persons related to
"substantial users") of facilities financed by IDBs or PABs should consult their
tax advisers before purchasing shares of a municipal fund because, for users of
certain of these facilities, the interest on those bonds is not exempt from
federal income tax. For these purposes, the term "substantial user" is defined
generally to include a "non-exempt person" who regularly uses in trade or
business a part of a facility financed from the proceeds of IDBs or PABs.

Up to 85% of social security and railroad retirement benefits may be
included in taxable income for recipients whose adjusted gross income (including
income from tax-exempt sources such as a municipal Fund) plus 50% of their
benefits exceeds certain base amounts. Exempt-interest dividends from the
Municipal funds still are tax-exempt to the extent described above and in the
Prospectus; they are only included in the calculation of whether a recipient's
income exceeds the established amounts.

If a municipal fund invests in any instruments that generate taxable
income, under the circumstances described in the Prospectus and in the
discussion of municipal market discount bonds below, the portion of any fund
dividend attributable to the interest earned thereon will be taxable to that
fund's shareholders as ordinary income to the extent of its earnings and profits
and only the remaining portion will qualify as an exempt-interest dividend. The
respective portions will be determined by the "actual earned" method, under
which the portion of any dividend that qualifies as an exempt-interest dividend
may vary, depending on the relative proportions of tax-exempt and taxable
interest earned during the dividend period. Moreover, if a municipal fund
realizes capital gain as a result of market transactions, any distribution of
that gain will be taxable to its shareholders.

Each municipal fund may invest in municipal bonds that are purchased,
generally not on their original issue, with market discount (that is, at a price
less than the principal amount of the bond or, in the case of a bond that was
issued with original issue discount, a price less than the amount of the issue
price plus accrued original issue discount) ("municipal market discount bonds").
If a bond's market discount is less than the product of (1) 0.25% of the
redemption price at maturity times (2) the number of complete years to maturity
after the taxpayer acquired the bond, then no market discount is considered to
exist. Gain on the disposition of a municipal market discount bond (other than a
bond with a fixed maturity date within one year from its issuance) generally is
treated as ordinary (taxable) income, rather than capital gain, to the extent of
the bond's accrued market discount at the time of disposition. Market discount
on such a bond generally is accrued ratably, on a daily basis, over the period
from the acquisition date to the date of maturity. In lieu of treating the
disposition gain as above, a municipal fund may elect to include market discount
in its gross income currently, for each taxable year to which it is
attributable.

Dividends from investment company taxable income paid to a shareholder
who, as to the United States, is a nonresident alien individual, nonresident
alien fiduciary of a trust or estate, foreign corporation or foreign partnership
("foreign shareholder") generally are subject to a 30% withholding tax, unless
the applicable tax rate is reduced by a treaty between the United States and the
shareholder's country of residence. Withholding does not apply to a dividend
paid to a foreign shareholder that is "effectively connected with the
[shareholder's] conduct of a trade or business within the United States," in

32
<PAGE>

which case the withholding requirements applicable to domestic taxpayers apply.
Exempt-interest dividends paid by the municipal funds are not subject to
withholding.

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

CALIFORNIA TAXES. In any year in which California Municipal Money Fund
qualifies as a RIC under the Internal Revenue Code and 50% or more of its assets
at the close of each quarter of its taxable year are invested in obligations the
interest on which is exempt from personal income taxation by the State of
California, the fund will be qualified under California law to pay
"exempt-interest" dividends which will be exempt from the California personal
income tax.

Individual shareholders of California Municipal Money Fund who reside in
California will not be subject to California personal income tax on
distributions received from the Fund to the extent such distributions are
attributable to interest on tax-exempt obligations issued by the State of
California or a California local government (or interest earned on tax-exempt
obligations of U.S. possessions or territories), provided that the fund
satisfies the requirement of California law that at least 50% of its assets at
the close of each quarter of its taxable year be invested in obligations the
interest on which is exempt from personal income taxation by the State of
California. Income distributions from the fund that are attributable to sources
other than those described in the preceding sentence will generally be taxable
to such shareholders as ordinary income. However, distributions from the fund,
if any, that are derived from interest on obligations of the U.S. government may
also be designated by the fund and treated by its shareholders as exempt from
California personal income tax, provided that the foregoing 50% requirement is
satisfied. In addition, distributions to such shareholders other than
exempt-interest dividends will be includable in income subject to the California
alternative minimum tax.

Shareholders of California Municipal Money Fund who are subject to the
California corporate franchise tax will be required to include distributions of
investment income and capital gains in their taxable income for purposes of that
tax. In addition, such distributions may be includable in income subject to the
alternative minimum tax.

Shares of California Municipal Money Fund will not be subject to the
California property tax.

The foregoing is a general, abbreviated summary of certain of the
provisions of the tax laws of the State of California presently in effect as
they directly govern the taxation of shareholders of California Municipal Money
Fund. These provisions are subject to change by legislative or administrative
action, and any such change may be retroactive with respect to fund
transactions. Shareholders are advised to consult with their own tax advisers
for more detailed information concerning California tax matters.

NEW JERSEY TAXES. New Jersey Municipal Money Fund anticipates that
substantially all dividends aid by it will not be subject to the New Jersey
gross income tax. In accordance with the provisions of New Jersey law as
currently in effect, distributions paid by a "qualified investment fund" will
not be subject to the New Jersey gross income tax to the extent the
distributions are attributable to income received as interest or gain from New
Jersey Municipal Securities or direct U.S. government obligations or certain
other specified obligations. To be classified as a qualified investment fund, at
least 80% of the fund's investments must consist of such obligations.
Distributions by a qualified investment fund that are attributable to most other
sources will be subject to the New Jersey gross income tax. If the fund
continues to qualify as a qualified investment fund, any gain on the redemption
of its shares will not be subject to the New Jersey gross income tax. To the
extent a shareholder of the fund is obligated to pay state or local taxes
outside of New Jersey, dividends earned by such shareholder may represent
taxable income.

The shares of New Jersey Municipal Money Fund are not subject to property
taxation by New Jersey or its political subdivisions.

33
<PAGE>

The foregoing is a general, abbreviated summary of certain of the
applicable provisions of New Jersey tax law presently in effect. These
provisions are subject to change by legislative, judicial or administrative
action and any such change may be either prospective or retroactive with respect
to Fund transactions. Shareholders are urged to consult with their own tax
advisers for more detailed information concerning New Jersey State tax matters.

NEW YORK TAXES. Individual shareholders of New York Municipal Money Fund
will not be required to include in their gross income for New York State and
City purposes any portion of distributions received from New York Municipal
Money Fund to the extent such distributions are directly attributable to
interest earned on tax-exempt obligations issued by New York State or any
political subdivisions thereof (including New York City) or interest earned on
obligations of U.S. possessions or territories to the extent interest on such
obligations is exempt from state taxation pursuant to federal law, provided that
New York Municipal Money Fund qualifies as a RIC under the Internal Revenue Code
and satisfies certain requirements, among others, that at least 50% of its
assets at the close of each quarter of its taxable year constitute obligations
which are tax-exempt for federal income tax purposes. Distributions from New
York Municipal Money Fund which are attributable to sources other than those
described in the preceding sentence (including interest on obligations of other
states and their political subdivisions) will generally be taxable to such
individual shareholders as ordinary income. Distributions to individual
shareholders by New York Municipal Money Fund which represents long-term capital
gains for federal income tax purposes will be treated as long-term capital gains
for New York State and City personal income tax purposes. (Certain undistributed
capital gains of New York Municipal Money Fund that are treated as (taxable)
long-term capital gains in the hands of shareholders will be treated as
long-term capital gains for New York State and City personal income taxes
purposes.)

Shareholders of New York Municipal Money Fund that are subject to the New
York State corporate franchise tax or the New York City general corporation tax
will be required to include exempt-interest dividends paid by New York Municipal
Money Fund in their "entire net income" for purposes of such taxes and will be
required to include their shares of New York Municipal Money Fund in their
investment capital for purposes of such taxes.

Shareholders of New York Municipal Money Fund will not be subject to the
unincorporated business taxation imposed by New York City solely by reason of
their ownership of shares in New York Municipal Money Fund. If a shareholder is
subject to the unincorporated business tax, income and gains distributed by New
York Municipal Money Fund will be subject to such tax except, in general, to the
extent such distributions are directly attributable to interest earned on
tax-exempt obligations issued by New York State or any political subdivision
thereof (including New York City).

Shares of New York Municipal Money Fund will not be subject to property
taxes imposed by New York State or City.

Interest on indebtedness incurred by shareholders to purchase or carry
shares of New York Municipal Money Fund (and certain other expenses relating
thereto) generally will not be deductible for New York State or City personal
income tax purposes.

Interest income of New York Municipal Money Fund which is distributed to
shareholders will generally not be taxable to New York Municipal Money Fund for
purposes of the New York State corporate franchise tax or City general
corporation tax.

New York Municipal Money Fund is subject to the corporate franchise
(income) tax measured by the entire net income base, the minimum taxable income
base or the fixed dollar minimum, whichever is greater. "Entire net income" of
New York Municipal Money Fund is federal "investment company taxable income"
with certain modifications. In addition, New York Municipal Money Fund is
permitted to deduct dividends paid to its shareholders in determining its
federal taxable income.

The foregoing is a general summary of certain provisions of federal, New
York State and City tax laws currently in effect as they directly govern the
taxation of shareholders of New York Municipal Money Fund. Further, these

34

provisions are subject to change by legislative or administrative action, and
any such change may be retroactive with respect to New York Municipal Money
Fund's transactions. Shareholders are advised to consult with their own tax
advisers for more detailed information concerning tax matters.

TAX-FREE INCOME VS. TAXABLE INCOME--TAX-FREE FUND. Table I below

OTHER INFORMATION

MASSACHUSETTS BUSINESS TRUSTS. Each Trust is an entity of the type
commonly known as a "Massachusetts business trust." Under Massachusetts law,
shareholders could, under certain circumstances, be held personally liable for
the obligations of a Trust. However, each Declaration of Trust disclaims
shareholder liability for acts or obligations of the Trust and requires that
notice of such disclaimer be given in each note, bond, contract, instrument,

37
<PAGE>

certificate or undertaking made or issued by the trustees or by any officers or
officer by or on behalf of that Trust, a Fund, the trustees or any of them in
connection with the Trust. Each Declaration of Trust provides for
indemnification from a fund's property for all losses and expenses of any
shareholder held personally liable for the obligations of the fund. Thus, the
risk of a shareholder's incurring financial loss on account of shareholder
liability is limited to circumstances in which a fund itself would be unable to
meet its obligations, a possibility which PaineWebber believes is remote and not
material. Upon payment of any liability incurred by a shareholder, the
shareholder paying such liability will be entitled to reimbursement from the
general assets of the fund. The trustees intend to conduct the operations of
each fund in such a way as to avoid, as far as possible, ultimate liability of
the shareholders for liabilities of the fund.

VOTING RIGHTS. Shareholders of each 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 each
series of the Corporation will be voted separately, except when an aggregate
vote of all the series is required by law.

The Corporations and Trusts do not hold annual meetings. There normally
will be no meetings of shareholders to elect board members unless fewer than a
majority of the board members holding office have been elected by shareholders.
The directors of a Corporation are required to call a meeting of shareholders
when requested in writing to do so by the shareholders of record holding at
least 25% of the Corporation's outstanding shares. Shareholders of record of no
less than two-thirds of the outstanding shares of a Trust may remove a board
member through a declaration in writing 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 10% of the outstanding shares of a Trust or 25% of the
outstanding shares of a Corporation.

CUSTODIAN AND RECORDKEEPING AGENT; TRANSFER AND DIVIDEND AGENT. State
Street Bank and Trust Company, located at One Heritage Drive, North Quincy,
Massachusetts 02171, serves as custodian and recordkeeping agent for each fund.
PFPC Inc., a subsidiary of PNC Bank, N.A., serves as each fund's transfer and
dividend disbursing agent. It is located at 400 Bellevue Parkway, Wilmington, DE
19809.

PRIOR NAMES. Prior to February 28, 1996, Municipal Money Market Series was
known as PaineWebber/Kidder, Peabody Municipal Money Market Series. Prior to
January 30, 1995, PaineWebber/Kidder, Peabody Municipal Money Market Series was
known as Kidder, Peabody Municipal Money Market Series. Prior to December 15,
1995, New Jersey Municipal Money Fund was known as New Jersey Series.

COMBINED PROSPECTUS. Although each fund is offering only its own shares,
it is possible that a fund might become liable for a misstatement in the
Prospectus about another fund. The board of each fund has considered this factor
in approving the use of a single, combined Prospectus.

COUNSEL. The law firm of Kirkpatrick & Lockhart LLP, 1800 Massachusetts
Avenue, N.W., Washington, D.C. 20036, serves as counsel to the Funds.
Kirkpatrick & Lockhart LLP also acts as counsel to PaineWebber and Mitchell
Hutchins in connection with other matters. The law firm of Orrick, Herrington &
Sutcliffe LLP, 400 Sansome Street, San Francisco, CA 94111, serves as counsel to
California Municipal Money Fund with respect to California law. The law firm of
Orrick, Herrington & Sutcliffe LLP, 666 Fifth Avenue, New York, New York
10103-0001, serves as counsel to New York Municipal Money Fund with respect to
New York law and New Jersey Municipal Money Fund with respect to New Jersey law.

AUDITORS. Ernst & Young LLP, 787 Seventh Avenue, New York, New York 10019,
serves as independent auditors for the funds.

APPENDIX A

SERVICES AVAILABLE THROUGH THE RMA PROGRAM TO RMA ACCOUNTHOLDERS

Shares of the Funds are available primarily to investors who are
Participants in the Resource Management Account (RMA) program offered by
PaineWebber and its correspondent firms. The following is a summary of some of
the services available to RMA Participants. For more complete information,
investors should refer to separate materials their Investment Executive can
provide them.

THE PAINEWEBBER RMA PREMIER STATEMENT. RMA Participants receive a monthly
Premier account statement, which provides consolidated information to assist
with portfolio management decisions and personal financial planning. The Premier
account statement summarizes securities transactions, card transactions and
checks (if applicable) and provides cost basis information and calculations of
unrealized and realized gains and losses on most investments. A "Summary of
Accounts" statement and a menu of customized statement options is available to
make the monthly reporting even more comprehensive.

PRELIMINARY AND YEAR-END SUMMARIES. RMA Participants receive preliminary
and year-end summary account statements that provide a comprehensive overview of
tax-related activity in the account during the year to help investors with tax
planning.

CHOICE OF MONEY MARKET FUNDS AND AUTOMATIC SWEEP OF UNINVESTED CASH. As
described more fully in the Prospectus under the heading Purchases--The RMA and
BSA Programs," RMA Participants select a money market fund as a primary fund
from a variety of taxable and tax-free money funds into which uninvested cash is
automatically swept on a daily basis. By automatically investing cash balances
into a money market fund, this sweep feature minimizes the extent to which an
investor's assets remain idle while held in the account pending investment.

CHECK WRITING. RMA Participants have ready access to the assets held in
their RMA through the check writing feature. There are no minimum check amounts
or per check charges. The RMA checks include an expense coding system that
enables the investor to track types of expenses for tax and financial planning.

DIRECT DEPOSIT. Regular payroll, pension, social security or other
payments may be eligible for electronic deposit into RMA Participants' accounts.

ELECTRONIC FUNDS TRANSFER/BILL PAYMENT SERVICE. RMA Participants can
electronically transfer money between their RMA and other financial
institutions, transfer funds to and from other PaineWebber accounts and pay
bills. A Bill Payment Service is available for an additional charge.

GOLD MASTERCARD(R). RMA Participants can elect to receive with a
complementary Gold MasterCard debit card that makes account assets easily
accessible. The Gold MasterCard is accepted by merchants both in the U.S. and
abroad, and can be used to obtain cash advances at thousands of automated teller
machines. Through MasterCard's enhanced MasterAssist-Registered Trademark- and
MasterPurchase-Registered Trademark-programs, investors can obtain other
benefits, including rental car insurance, emergency medical and travel
assistance, legal services and purchase protection.

EXTENDED ACCOUNT PROTECTION. Securities held in an RMA Account by
PaineWebber or one of its correspondent firms are protected for up to the net
equity through private insurance in the event of the liquidation or failure of
the firm. This protection is in addition to the $500,000 in protection provided
to accountholders by the Securities Investor Protection Corporation ("SIPC").
Neither the SIPC protection nor the additional account protection insurance
applies to shares of the Funds because such shares are registered directly in
the name of the shareholder, and not in the name of PaineWebber or one of its
correspondent firms.

<PAGE>

RESOURCE ACCUMULATION PLAN-SM-. The Resource Accumulation Plan is an
automatic mutual fund investment program that provides participants the ability
to purchase shares of select mutual funds on a regular, periodic basis. The
minimum purchase in the program is $100 per investment; however, initial minimum
purchase requirements of the designated mutual fund(s) must be met before an
investor can participate in this program. The participant must receive a
prospectus, which contains more complete information (including charges and
expenses), for each fund before the application form to participate in the
Resource Accumulation Plan is submitted.

FINANCIAL SERVICES CENTER AND RESOURCELINE-REGISTERED TRADEMARK-. RMA
Participants have around the clock access to information concerning their RMA.
This service is available by calling (800) RMA-1000. RMA representatives are
available at the Financial Services Center from 7:30 a.m. to 8:00 p.m. (Eastern
time) weekdays, and from 8:00 a.m. to 4:00 p.m. (Eastern time) weekends, to
answer inquiries from Participants regarding their accounts, and ResourceLine,
an automated voice response system, provides 24 hour account information.

MARGIN. RMA Participants may choose to have a margin feature as part of
their RMA.

APPENDIX B

SERVICES AVAILABLE THROUGH THE BSA PROGRAM FOR BSA ACCOUNTHOLDERS

Shares of the Funds are available to investors who are Participants in the
Business Services Account ("BSA")-Registered Trademark- program. The following
is a summary of some of the services that are available to BSA Participants. For
more complete information, investors should refer to separate materials their
Investment Executives can provide them.

PREMIER BUSINESS SERVICES ACCOUNT STATEMENT--BSA Participants receive a
monthly Premier statement, which provides consolidated information to assist
with portfolio management decisions and business finances. The Premier statement
summarizes securities transactions, card transactions, and checks in
chronological order with running cash and money fund balances. The "Portfolio
Management" feature provides cost basis information where available as well as
calculations of gains and losses on most investments. A menu of customized
statement options is now available to make the monthly reporting more
comprehensive.

PRELIMINARY AND YEAR-END SUMMARIES STATEMENT--BSA Participants receive
preliminary and year-end summary information statements that provide a
comprehensive overview of tax-related activity in the account during the year to
help investors plan.

CHOICE OF MONEY MARKET FUNDS AND AUTOMATIC SWEEP OF UNINVESTED CASH--As
described more fully in the Prospectus under the heading "Purchases--The RMA and
BSA Programs," BSA Participants select a money market fund as a primary fund
from a variety of taxable and tax-free money funds into which uninvested cash is
automatically swept on a daily basis. By automatically investing cash balances
into a money market fund, this sweep feature minimizes the extent to which an
investor's assets remain idle while held in the account pending investment.
CHECK WRITING--BSA Participants have ready access to the assets held in their
BSA through the check writing feature. There are no minimum check amounts.
Participants can order from a number of business check styles to suit their
check writing needs. The BSA checks also include an expense code system that
enables investors to track business expense types for tax and financial
planning. MASTERCARD BUSINESSCARD-REGISTERED TRADEMARK---BSA Participants can
elect to receive a complementary MasterCard BusinessCard debit card for easy
access to account assets. The MasterCard BusinessCard is accepted worldwide, and
can be used to obtain cash at thousands of automated teller machines. Through

MasterPurchase-Registered Trademark- programs, investors can obtain other
benefits including full value primary rental car insurance, emergency medical
and travel assistance, legal services and purchase protection.

MARGIN--BSA Participants may choose to have a margin feature as part of
their BSA.

EXTENDED ACCOUNT PROTECTION--Securities held in a BSA by PaineWebber or
one of its correspondent firms are protected for up to the net equity through
private insurance in the event of the liquidation or failure of the firm. This
protection is in addition to the $500,000 in protection provided to
accountholders by the Securities Investor Protection Corporation ("SIPC").
Neither the SIPC protection nor the additional account protection insurance
applies to shares of the Funds because such shares are registered directly in
the name of the shareholder, and not in the name of PaineWebber or one of its
correspondent firms.

FINANCIAL SERVICES CENTER AND RESOURCELINE-REGISTERED TRADEMARK---BSA
Participants can call the Financial Services Center at (800) BSA-0140 from 7:30

24 hours a day by calling (800) 762-1000.

ELECTRONIC FUNDS TRANSFER/PAYMENT SERVICE--BSA Participants have the
option to initiate transfers of funds to and from their accounts, pay bills and
vendors through an electronic fund transfer service. Unlimited transfers to the
BSA from other financial institutions and 20 free transfers/payments out of the
BSA are permitted monthly with nominal fees thereafter. Participants send
regular or variable payments simply by calling an 800 number.

CARD RECEIVABLES PROCESSING--BSA account holders that transact business
with their clients using credit cards and debit cards, can have these receipts
automatically deposited into their BSA where their funds will be swept into
their primary sweep Fund thereby continuously earning dividends. Working through
your current merchant processor, or a PaineWebber referral, this service is a
simple way to enhance earnings on your business's cash flow.

Item 25. INDEMNIFICATION
---------------

Section 2 of "Indemnification" in Article X of the Declaration of
Trust

<PAGE>

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

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

Section 2 of Article XI of the Declaration of Trust additionally provides
that, subject to the provisions of Section 1 of Article XI and to Article X,
trustees shall not be liable for errors of judgment or mistakes of fact or law,
or for any act or omission in accordance with advice of counsel or other
experts, or failing to follow such advice, with respect to the meaning and
operation of the Declaration of Trust.

Article IX of the By-Laws provides that the Registrant may purchase and
maintain insurance on behalf of any person who is or was a trustee, officer or
employee of the Trust, or is or was serving at the request of the Trust as a
trustee, officer or employee of a corporation, partnership, joint venture, trust
or other enterprise against any liability asserted against him or her and
incurred by him or her in any such capacity or arising 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, provided that the Registrant may not acquire
insurance protecting any trustee or officer against liability to the Registrant
or its shareholders to which he or she would otherwise be subject by reason of
willful misfeasance, bad faith, gross negligence, or reckless disregard of the
duties involved in the conduct of his or her office.

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

Section 9 of the Sub-Advisory and Sub-Administration Contract between
PaineWebber and Mitchell Hutchins contains provisions similar to Section 9 of
the Investment Advisory and Administration Contract between the Registrant and
PaineWebber, with respect to PaineWebber.

Section 9 of the Distribution Contract between the Registrant and
PaineWebber provides that the Registrant will indemnify PaineWebber, its
officers, directors and controlling persons against all liabilities arising from
any alleged untrue statement of material fact in the Registration Statement or
from any alleged omission to state in the Registration Statement a material fact
required to be stated in it or necessary to make the statements in it, in light
of the circumstances under which they were made, not misleading, except insofar
as liability arises from untrue statements or omissions made in reliance upon
and in conformity with information furnished by PaineWebber 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

<PAGE>

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 also
provides that PaineWebber agrees to indemnify, defend and hold the Registrant,
its officers and trustees free and harmless of any claims arising out of any
alleged untrue statement or any alleged omission of material fact contained in
information furnished by PaineWebber for use in the Registration Statement or
arising out of an agreement between PaineWebber and any retail dealer, or
arising out of supplementary literature or advertising used by PaineWebber in
connection with the Contract.

Section 10 of the Distribution Contract contains provisions similar to
that of Section 10 of the Investment Advisory and Administration Contract, with
respect to PaineWebber, as appropriate.

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