                   PAINEWEBBER NATIONAL TAX-FREE INCOME FUND
                   INVESTMENT OBJECTIVE, STRATEGIES AND RISKS

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

FUND OBJECTIVE

High current income exempt from federal income tax, consistent with the
preservation of capital and liquidity within the fund's quality standards.

PRINCIPAL INVESTMENT STRATEGIES

The fund normally invests substantially all its assets in municipal bonds. These
are bonds and similar securities that are exempt from federal income tax. The
fund may invest up to 20% of its total assets in municipal bonds that are
subject to the federal alternative minimum tax.

The fund invests primarily in municipal bonds that are investment grade, but it
also invests, to a lesser extent, in lower rated bonds. The fund may (but is not
required to) use interest rate futures contracts and other derivatives to help
manage its portfolio duration. "Duration" is a measure of the fund's exposure to
interest rate risk.

The fund's investment adviser, Mitchell Hutchins Asset Management Inc., uses a
"top down" investment process to select bonds for the fund. Mitchell Hutchins
determines the appropriate duration for the fund's portfolio based on its
assessment of whether market interest rates are likely to rise or fall and on
whether rates are most attractive for longer, medium or shorter term bonds.
Mitchell Hutchins allocates the fund's investments among market sectors, such as
general obligation or revenue bonds and higher or lower credit quality, by
analyzing the relative attractiveness of rates and market opportunities in each
sector. Within the limits set by these allocation decisions, Mitchell Hutchins
selects specific bonds based on an analysis of their credit quality and terms.

PRINCIPAL RISKS

An investment in the fund is not guaranteed; you may lose money by investing in
the fund. The principal risks presented by the fund are:

- INTEREST RATE RISK--The value of the fund's investments generally will fall
  when interest rates rise.

- CREDIT RISK--Municipal bond issuers may fail to make payments when due, or
  they may become less willing or less able to do so.

- POLITICAL RISK--The fund's investments are significantly affected by political
  changes, including legislation proposals which may make municipal bonds less
  attractive in comparison to taxable bonds.

- RELATED SECURITIES CONCENTRATION RISK--Because the fund may invest more than
  25% of its total assets in municipal bonds that are issued to finance similar
  projects, economic, business, or political developments or changes that affect
  one municipal bond also may affect other municipal bonds in the same sector.

- DERIVATIVES RISK--The fund's investments in derivatives may rise or fall more
  rapidly than other investments.

More information about these and other risks of an investment in the fund is
provided below in "More About Risks and Investment Strategies."

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

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

RISK/RETURN BAR CHART AND TABLE

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

The bar chart shows how the fund's performance has varied from year to year. The
bar chart shows Class A shares because they have the longest performance history
of any class of fund shares. The chart does not reflect the effect of sales
charges; if it did, the total returns shown would be lower.

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

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

EXAMPLE

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

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

                     PAINEWEBBER MUNICIPAL HIGH INCOME FUND
                   INVESTMENT OBJECTIVE, STRATEGIES AND RISKS

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

FUND OBJECTIVE

High current income exempt from federal income tax.

PRINCIPAL INVESTMENT STRATEGIES

The fund normally invests substantially all of its assets in municipal bonds.
These are bonds and similar securities that are exempt from federal income tax.
The fund may invest without limit in municipal bonds that are subject to the
federal alternative minimum tax (AMT). The fund invests in these bonds when its
investment adviser, Mitchell Hutchins Asset Management Inc., believes they offer
attractive yields relative to municipal bonds that have similar investment
characteristics but are not subject to AMT.

The fund invests primarily in municipal bonds that are of medium or lower credit
quality. These include high yield bonds, which are not investment grade and are
sometimes called "junk bonds." The fund may (but is not required to) use
interest rate futures contracts and other derivatives to help manage its
portfolio duration. "Duration" is a measure of the fund's exposure to interest
rate risk.

Mitchell Hutchins uses a "top down" investment process to select bonds for the
fund. Mitchell Hutchins determines the appropriate duration for the fund's
portfolio based on its assessment of whether market interest rates are likely to
rise or fall and on whether rates are most attractive for longer, medium or
shorter term bonds. Mitchell Hutchins allocates the fund's investments among
market sectors, such as general obligation or revenue bonds and higher or lower
credit quality, by analyzing the relative attractiveness of rates and market
opportunities in each sector. Within the limits set by these allocation
decisions, Mitchell Hutchins selects specific bonds based on an analysis of
their credit quality and terms.

PRINCIPAL RISKS

An investment in the fund is not guaranteed; you may lose money by investing in
the fund. The principal risks presented by the fund are:

- CREDIT RISK--Municipal bond issuers may fail to make payments when due, or
  they may become less willing or less able to do so.

- INTEREST RATE RISK--The value of the fund's investments generally will fall
  when interest rates rise.

- POLITICAL RISK--The fund's investments are significantly affected by political
  changes, including legislation proposals which may make municipal bonds less
  attractive in comparison to taxable bonds.

- SINGLE ISSUER CONCENTRATION RISK--Because the fund is non-diversified, it can
  invest more of its assets in a single issuer than a diversified fund. As a
  result, changes in the value of a single issuer's securities can have a
  greater impact on the fund's performance.

- RELATED SECURITIES CONCENTRATION RISK--Because the fund may invest more than
  25% of its total assets in municipal bonds that are issued to finance similar
  projects, economic, business, or political developments or changes that affect
  one municipal bond also may affect other municipal bonds in the same sector.

- DERIVATIVES RISK--The fund's investments in derivatives may rise or fall more
  rapidly than other investments.

More information about these and other risks of an investment in the fund is
provided below in "More About Risks and Investment Strategies."

EXAMPLE

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

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

                  PaineWebber California Tax-Free Income Fund
                   INVESTMENT OBJECTIVE, STRATEGIES AND RISKS

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

FUND OBJECTIVE

High current income exempt from federal income tax and California personal
income tax, consistent with the preservation of capital and liquidity within the
fund's quality standards.

PRINCIPAL INVESTMENT STRATEGIES

The fund normally invests substantially all its assets in California municipal
bonds. These are bonds and similar securities that are exempt from federal
income tax and from California personal income tax. The fund may invest up to
20% of its total assets in California municipal bonds that are subject to the
federal alternative minimum tax.

The fund invests primarily in California municipal bonds that are investment
grade, but it also invests, to a lesser extent, in lower rated bonds. The fund
may (but is not required to) use interest rate futures contracts and other
derivatives to help manage its portfolio duration. "Duration" is a measure of
the fund's exposure to interest rate risk.

The fund's investment adviser, Mitchell Hutchins Asset Management Inc., uses a
"top down" investment process to select bonds for the fund. Mitchell Hutchins
determines the appropriate duration for the fund's portfolio based on its
assessment of whether market interest rates are likely to rise or fall and on
whether rates are most attractive for longer, medium or shorter term bonds.
Mitchell Hutchins allocates the fund's investments among market sectors, such as
general obligation or revenue bonds and higher or lower credit quality, by
analyzing the relative attractiveness of rates and market opportunities in each
sector. Within the limits set by these allocation decisions, Mitchell Hutchins
selects specific bonds based on an analysis of their credit quality and terms.

PRINCIPAL RISKS

An investment in the fund is not guaranteed; you may lose money by investing in
the fund. The principal risks presented by the fund are:

- INTEREST RATE RISK--The value of the fund's investments generally will fall
  when interest rates rise.

- CREDIT RISK--Municipal bond issuers may fail to make payments when due, or
  they may become less willing or less able to do so.

- SINGLE STATE CONCENTRATION RISK--Because the fund invests substantially all
  its assets in California municipal bonds, its performance will be more
  severely affected by unfavorable political or economic conditions in
  California than a more geographically diverse fund.

- POLITICAL RISK--The fund's investments are significantly affected by political
  changes, including legislation proposals which may make municipal bonds less
  attractive in comparison to taxable bonds.

- RELATED SECURITIES CONCENTRATION RISK--Because the fund may invest more than
  25% of its total assets in municipal bonds that are issued to finance similar
  projects, economic, business, or political developments or changes that affect
  one municipal bond also may affect other municipal bonds in the same sector.

- DERIVATIVES RISK--The fund's investments in derivatives may rise or fall more
  rapidly than other investments.

More information about these and other risks of an investment in the fund is
provided below in "More About Risks and Investment Strategies."

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

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

RISK/RETURN BAR CHART AND TABLE

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

The bar chart shows how the fund's performance has varied from year to year. The
bar chart shows Class A shares because they have the longest performance history
of any class of fund shares. The chart does not reflect the effect of sales
charges; if it did, the total returns shown would be lower.

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

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

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

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

                   PAINEWEBBER NEW YORK TAX-FREE INCOME FUND
                   INVESTMENT OBJECTIVE, STRATEGIES AND RISKS

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

FUND OBJECTIVE

High current income exempt from federal income tax and from New York State and
New York City personal income taxes.

PRINCIPAL INVESTMENT STRATEGIES

The fund normally invests substantially all its assets in New York municipal
bonds. These are bonds and similar securities that are exempt from federal
income tax and from New York State and New York City personal income taxes. The
fund may invest up to 20% of its total assets in New York municipal bonds that
are subject to the federal alternative minimum tax.

The fund invests primarily in New York municipal bonds that are investment
grade, but it also invests, to a lesser extent, in lower rated bonds. The fund
may (but is not required to) use interest rate futures contracts and other
derivatives to help manage its portfolio duration. "Duration" is a measure of
the fund's exposure to interest rate risk.

The fund's investment adviser, Mitchell Hutchins Asset Management Inc., uses a
"top down" investment process to select bonds for the fund. Mitchell Hutchins
determines the appropriate duration for the fund's portfolio based on its
assessment of whether market interest rates are likely to rise or fall and on
whether rates are most attractive for longer, medium or shorter term bonds.
Mitchell Hutchins allocates the fund's investments among market sectors, such as
general obligation or revenue bonds and higher or lower credit quality, by
analyzing the relative attractiveness of rates and market opportunities in each
sector. Within the limits set by these allocation decisions, Mitchell Hutchins
selects specific bonds based on an analysis of their credit quality and terms.

PRINCIPAL RISKS

An investment in the fund is not guaranteed; you may lose money by investing in
the fund. The principal risks presented by the fund are:

- INTEREST RATE RISK--The value of the fund's investments generally will fall
  when interest rates rise.

- CREDIT RISK--Bond issuers may fail to make payments when due, or they may
  become less willing or less able to do so.

- SINGLE STATE CONCENTRATION RISK--Because the fund invests substantially all
  its assets in New York municipal bonds, its performance will be more severely
  affected by unfavorable political or economic conditions in New York than a
  more geographically diverse fund.

- POLITICAL RISK--The fund's investments are significantly affected by political
  changes, including legislation proposals which may make municipal bonds less
  attractive in comparison to taxable bonds.

- SINGLE ISSUER CONCENTRATION RISK--Because the fund is non-diversified, it can
  invest more of its assets in a single issuer than a diversified fund. As a
  result, changes in the value of a single issuer's securities can have a
  greater impact on the fund's performance.

- RELATED SECURITIES CONCENTRATION RISK--Because the fund may invest more than
  25% of its total assets in municipal bonds that are issued to finance similar
  projects, economic, business, or political developments or changes that affect
  one municipal bond also may affect other municipal bonds in the same sector.

- DERIVATIVES RISK--The fund's investments in derivatives may rise or fall more
  rapidly than other investments.

More information about these and other risks of an investment in the fund is
provided below in "More About Risks and Investment Strategies."

RISK/RETURN BAR CHART AND TABLE

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

The bar chart shows how the fund's performance has varied from year to year. The
bar chart shows Class A shares because they have the longest performance history
of any class of fund shares. The chart does not reflect the effect of sales
charges; if it did, the total returns shown would be lower.

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

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

*The fund and Mitchell Hutchins have entered into a written expense
 reimbursement agreement. Mitchell Hutchins is contractually obligated to
 reimburse the fund to the extent that the fund's expenses through June 30, 2001
 otherwise would exceed the "Net Expenses" rate for each class as shown above.
 The fund has agreed to repay Mitchell Hutchins for those reimbursed expenses if
 it can do so over the following three years without causing the fund's expenses
 in any of those years to exceed those "Net Expenses" rates.

EXAMPLE

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

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

                        MORE ABOUT RISKS AND INVESTMENT
                                   STRATEGIES

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

PRINCIPAL RISKS

The main risks of investing in the 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 bond will not make
principal or interest payments when they are due. Even if an issuer does not
default on a payment, a municipal bond's value may decline if the market
believes that the issuer has become less able, or less willing, to make payments
on time. Even high quality municipal bonds are subject to some credit risk.
However, credit risk is greater for lower quality municipal bonds. Municipal
bonds that are not investment grade involve high credit risk and are considered
speculative. High yield, lower quality bonds may fluctuate in value more than
higher quality bonds and, during periods of market volatility, may be more
difficult to sell at the time and price a fund desires.

Some municipal bonds are "insured bonds," which means that a private insurer
guarantees payment even if the issuer of the bond defaults. Insured bonds are
subject to credit risks relating to both the issuer and the insurer, since if
the market believes that either of them has become less able to make payments,
the value of the municipal bond may decline. Bond insurance does not protect
against interest rate or other non-credit risks.

DERIVATIVES RISK.  The value of "derivatives" - so-called because their value
"derives" from the value of an underlying asset, reference rate or index - may
rise or fall more rapidly than other investments. For some derivatives, it is
possible for a fund to lose more than the amount it invested in the derivative.
Options and futures contracts are examples of derivatives. A fund's use of
derivatives may not succeed for various reasons, including unexpected changes in
the values of the derivatives or the assets underlying them. Also, if a fund
uses derivatives as a hedge, the hedge will not succeed if changes in the values
of the derivatives are not matched by opposite changes in the values of the
assets being hedged.

INTEREST RATE RISK.  The value of municipal bonds generally can be expected to
fall when interest rates rise and to rise when interest rates fall. Interest
rate risk is the risk that interest rates will rise, so that the value of a
fund's investments in municipal bonds will fall. In general, the value of
municipal bonds with longer durations fluctuates more in response to interest
rate changes than municipal bonds with shorter durations. Bonds that are subject
to "call" provisions may be prepaid at specified times prior to their scheduled
maturity dates, especially if prevailing interest rates are lower than they were
when the bond was issued. A fund may need to reinvest the proceeds of called
bonds in investments that pay lower rates, thus reducing the fund's income.

POLITICAL RISK.  The municipal bond market can be significantly affected by
political changes, including legislation or proposals at either the state or the
federal level to eliminate or limit the tax-exempt status of municipal bond
interest or the tax-exempt status of a municipal bond fund's dividends.
Similarly, reductions in tax rates may make municipal bonds less attractive in
comparison to taxable bonds. Legislatures also may fail to appropriate funds
needed to pay municipal bond obligations. These events could cause the value of
a fund's investments in municipal bonds to fall and might adversely affect the
tax-exempt status of the fund's investments or of the dividends that the fund
pays. During periods of uncertainty, the prices of municipal securities can
become volatile.

RELATED SECURITIES CONCENTRATION RISK.  Each fund may invest more than 25% of
its total assets in municipal bonds 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 bond also may affect other municipal bonds in the same sector. As a
result, the funds are subject to greater risk than funds that do not follow this
practice.

SINGLE ISSUER CONCENTRATION RISK.  Municipal High Income Fund and New York
Tax-Free Income Fund are non-diversified. A non-diversified fund may invest more
than 5% of its total assets in securities of a single issuer to a greater extent
than a diversified fund. When a fund holds a large position in the securities of
one issuer, changes in the financial condition or in the market's assessment of
that issuer may cause larger changes in the fund's total return and in the price
of its shares than if the fund held a smaller position.

SINGLE STATE CONCENTRATION RISK.  California Tax-Free Income Fund and New York
Tax-Free Income Fund invest primarily in the municipal bonds of a single state,
and their performance 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 these funds could be more volatile and
involve greater risk than an investment in a more geographically diversified
fund. Information on factors affecting investments in California and New York
municipal bonds is contained in the SAI.

ADDITIONAL INVESTMENT STRATEGIES

DEFENSIVE POSITIONS; CASH RESERVES.  To protect itself from adverse market
conditions, a fund may take a temporary defensive position that is different
from its normal investment strategy. This means that the fund may temporarily
invest a larger-than-normal part, or even all, of its assets in cash or money
market instruments that pay taxable interest. Since these investments provide
relatively low income that is taxable, a defensive position may not be
consistent with achieving a fund's investment objective. However, each fund also
may invest in money market instruments that pay tax-exempt interest on an
unlimited basis as part of its ordinary investment strategy.

PORTFOLIO TURNOVER.  Each fund may engage in frequent trading in order to
achieve its investment objective. Frequent trading may result in portfolio
turnover over 100% or more (high portfolio turnover).

Frequent trading may increase the portion of a fund's capital gains that are
realized for tax purposes in any given year. This may increase the fund's
taxable dividends in that year. Frequent trading also may increase the portion
of a fund's realized capital gains that are considered "short-term" for tax
purposes. Shareholders will pay higher taxes on dividends that represent
short-term capital gains than they would pay on dividends that represent
long-term capital gains. Frequent trading also may result in higher fund
expenses due to transaction costs.

The funds do not restrict the frequency of trading in order to limit expenses or
the tax effect that the fund's dividends may have on shareholders.

FLEXIBLE PRICING

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

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

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

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

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

(2) Mitchell Hutchins pays 1% to PaineWebber.

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

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

- your spouse, parents or children under age 21;

- your Individual Retirement Accounts (IRAs);
- certain employee benefit plans, including 401(k) plans;

- a company that you control;

- a trust that you created;

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

- accounts with the same adviser.

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

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

- Buy these shares through a PaineWebber Financial Advisor who was formerly
  employed as an investment executive with a competing brokerage firm that was
  registered as a broker-dealer with the SEC, and
  -- you were the Financial Advisor's client at the competing brokerage firm;

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

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

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

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

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

- Acquire these shares through a PaineWebber InsightOne-SM- Program brokerage
  account.

CLASS B SHARES
Class B shares have a contingent deferred sales charge. When you purchase Class
B shares, we invest 100% of your purchase in fund shares. However, you may have
to pay the deferred sales charge when you sell your fund shares, depending on
how long you own the shares.

Class B shares pay an annual 12b-1 distribution fee of 0.75% of average net
assets, as well as an annual 12b-1 service fee of 0.25% of average net assets.
If you hold your Class B shares for six years, they will automatically convert
to Class A shares, which have lower ongoing expenses.

If you sell Class B shares before the end of six years, you will pay a deferred
sales charge. We calculate the deferred sales charge by multiplying the lesser
of the net asset value of the Class B shares at the time of purchase or the net
asset value at the time of sale by the percentage shown below:

<TABLE>
<CAPTION>
                                PERCENTAGE BY WHICH

SHARES WITHIN:                 VALUE IS MULTIPLIED:
--------------                 ---------------------
<S>                            <C>

6th year since purchase......              1
7th year since purchase......           None
</TABLE>

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

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

- First, Class B shares representing reinvested dividends, and

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

SALES CHARGE WAIVERS.  You may qualify for a waiver of the deferred sales charge
on a sale of shares if:

- You participate in the Systematic Withdrawal Plan;

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

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

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

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

CLASS C SHARES

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

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

shares do not convert to another class of shares. This means that you will pay
the 12b-1 fees for as long as you own your shares.

Class C shares also have a contingent deferred sales charge. You may have to pay
the deferred sales charge if you sell your shares within one year of the date
you purchased them. We calculate the deferred sales charge on sales of Class C
shares by multiplying 0.75% by the lesser of the net asset value of the Class C
shares at the time of purchase or the net asset value at the time of sale. We
will not impose the deferred sales charge on Class C shares representing
reinvestment of dividends or on withdrawals in the first year after purchase of
up to 12% of the value of your Class C shares under the Systematic Withdrawal
Plan.

You may be eligible to sell your shares without paying a contingent deferred
sales charge if you are a 401(k) or 403(b) qualified employee benefit plan with
fewer than 100 employees or less than $1 million in assets.

NOTE ON SALES CHARGE WAIVERS REGARDING CLASS A, CLASS B AND CLASS C SHARES

If you think you qualify for any of the sales charge waivers described above,
you will need to provide documentation to PaineWebber or the funds. For more
information, you should contact your PaineWebber Financial Advisor or
correspondent firm or call 1-800-647-1568. If you want information on the funds'
Systematic Withdrawal Plan, see the SAI or contact your PaineWebber Financial
Advisor or correspondent firm.

CLASS Y SHARES

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

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

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

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

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

Class Y shares do not pay ongoing 12b-1 distribution or service fees or sales
charges. The ongoing expenses for Class Y shares are the lowest of all the
classes.

BUYING SHARES

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

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

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

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

- Mailing an application with a check; or

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

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

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

<TABLE>
<CAPTION>
MINIMUM INVESTMENTS:
<S>                          <C>
To open an account.........       $1,000
To add to an account.......       $  100
</TABLE>

Each fund may waive or reduce these amounts for:

- Employees of PaineWebber or its affiliates; or

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

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

timer. A fund may notify the market timer that a purchase order or an exchange
has been rejected after the day the order is placed.

SELLING SHARES

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

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

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

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

- Your name and address;

- The fund's name;

- The fund account number;

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

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

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

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

It costs each fund money to maintain shareholder accounts. Therefore, the funds
reserve 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. A fund will not repurchase shares in accounts that fall below $500 solely
because of a decrease in the fund's net asset value.

EXCHANGING SHARES

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

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

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

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

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

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

- Your name and address;

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

- Your account number;

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

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

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

PRICING AND VALUATION

The price at which you may buy, sell or exchange fund shares is based on net
asset value per share. Each fund calculates net asset value on days that the New
York Stock Exchange is open. Each fund calculates net asset value separately for
each class as of the close of regular trading on the NYSE (generally,
4:00 p.m., Eastern time). The NYSE normally is not open, and the funds do not
price their shares, on most national holidays and on Good Friday. If trading on
the NYSE is halted for the day before 4:00 p.m., Eastern time, the fund's net
asset value per share will be calculated as of the time trading was halted.

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

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

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

Judgment plays a greater role in valuing thinly traded securities, including
many lower-rated municipal bonds, because there is less reliable, objective data
available.

ADVISORY FEES

The funds paid fees to Mitchell Hutchins for advisory and administration

expressed as a percentage of a fund's average daily net assets:

<TABLE>
<S>                                      <C>
National Tax-Free Income Fund..........    0.50%
Municipal High Income Fund.............    0.60%
California Tax-Free Income Fund........    0.30%*
New York Tax-Free Income Fund..........    0.60%
</TABLE>

---------
*This is the effective rate resulting from Mitchell Hutchins' waiver of 0.20% of
 its 0.50% advisory fee.

OTHER INFORMATION

The funds have received an exemptive order from the SEC that permits their
boards to appoint and replace sub-advisers and to amend sub-advisory contracts
without shareholder approval. A fund's shareholders must approve this policy
before its board may implement it. As of the date of this prospectus, the
shareholders of the funds have not been asked to do so.

                              DIVIDENDS AND TAXES

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

DIVIDENDS

Each fund normally declares dividends daily and pays them monthly. Each fund
distributes substantially all of its gains, if any, annually.

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

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

TAXES

Each fund seeks to pay dividends that are exempt from federal income tax.
California Tax-Free Income Fund also seeks to pay dividends that are exempt from
California personal income tax, and New York Tax-Free Income Fund to pay
dividends that are exempt from New York State and New York City personal income
taxes.

A portion of each fund's dividends may be subject to federal and state income
taxes. Each fund also may pay dividends that are subject to the federal
alternative minimum tax.

Each fund's distributions of capital gains are taxable to you for federal income
tax purposes. Distributions of capital gains may be taxed at a lower rate than
ordinary (taxable) income, depending on whether the fund held the assets that
generated the gains for more than 12 months.

Your fund will tell you annually how you should treat its dividends for federal
and state income tax purposes.

Any taxable dividends you receive from a fund will be taxable to you regardless
of whether you receive them in additional fund shares or in cash.

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

The following financial highlights tables are intended to help you understand
the funds' financial performance for the past 5 years. Shorter periods are shown
for classes of fund shares that have existed for less than 5 years. Certain
information reflects financial results for a single fund share. In the tables,
"total investment return" represents the rate that an investor would have earned
(or lost) on an investment in a fund (assuming reinvestment of all dividends).

This information in the financial highlights has been audited by Ernst & Young
LLP, independent auditors, whose reports, along with the funds' financial
statements, are included in the funds' Annual Report to Shareholders. The Annual

(1)  Total investment return is calculated assuming a $1,000 investment on the
     first day of each period reported, reinvestment of all dividends and
     distributions at net asset value on the payable dates and a sale at net
     asset value on the last day of each period reported. The figures do not
     include any applicable sales charges or program fees; results would be
     lower if they were included. Total investment return for periods of less
     than one year has not been annualized.
(2)  These ratios include non-recurring acquisition expenses of 0.03%.

(1)  Total investment return is calculated assuming a $1,000 investment on the
     first day of each period reported, reinvestment of all dividends and
     distributions at net asset value on the payable dates and a sale at net
     asset value on the last day of each period reported. The figures do not
     include any applicable sales charges or program fees; results would be
     lower if they were included. Total investment return for periods of less
     than one year has not been annualized.

(1)  Total investment return is calculated assuming a $1,000 investment on the
     first day of each period reported, reinvestment of all dividends and
     distributions at net asset value on the payable dates and a sale at net
     asset value on the last day of each period reported. The figures do not
     include any applicable sales charges or program fees; results would be
     lower if they were included. Total investment return for periods of less
     than one year has not been annualized.
