Flexible Pricing System:         Investors may select Class A, Class B or
                                 Class C shares, each with a public offering
                                 price that reflects different sales charges
                                 and expense levels. See 'Flexible Pricing
                                 System,' 'Purchases,' 'Redemptions' and

                                  (Continued)
- --------------------------------------------------------------------------------
 
     WHO SHOULD INVEST.  Each Fund has its own suitability considerations and
risk factors, as summarized below and described in detail under 'Investment
Objectives and Policies.' While no single Fund is intended to provide a complete
or balanced investment program, each can serve as one component of an investor's
long-term program to accumulate assets for retirement, college tuition or other
major goals. The Funds are not suitable for tax-exempt institutions or qualified
retirement plans, because those investors cannot take advantage of the
tax-exempt character of the Funds' dividends.
 
          CALIFORNIA TAX-FREE INCOME FUND.  The Fund invests primarily in
     investment grade debt obligations of varying maturities issued by the State
     of California, its municipalities and public authorities or by other
     issuers if such obligations pay interest that is exempt from federal income
     tax and California personal income tax ('California Obligations').
     Accordingly, the Fund is designed for investors seeking income that is
     exempt from those taxes.
 
          NATIONAL TAX-FREE INCOME FUND.  The Fund invests primarily in
     investment grade debt obligations of varying maturities issued by states,
     municipalities and public authorities and other issuers that pay interest
     that is exempt from federal income tax ('municipal securities' or
     'municipal obligations'). Accordingly, the Fund is designed for investors
     seeking income that is exempt from federal income tax.
 
          MUNICIPAL HIGH INCOME FUND.  The Fund invests primarily in high yield,
     high risk medium and lower grade municipal obligations that pay interest
     that is exempt from federal income tax. Accordingly, the Fund is designed
     for investors seeking high current income that is exempt from federal
     income tax and who can assume the risks associated with the types of
     securities in which the Fund invests.
 
          NEW YORK TAX-FREE INCOME FUND.  The Fund invests primarily in
     investment grade debt obligations of varying maturities issued by the State
     of New York, its municipalities and public authorities or by other issuers
     if such obligations pay interest that is exempt from federal income tax as
     well as New York State and New York City personal income taxes ('New York

     Obligations'). Accordingly, the Fund is designed for investors seeking
     income that is exempt from those taxes.
 
     RISK FACTORS.  There can be no assurance that any Fund will achieve its
investment objective, and each Fund's net asset value fluctuates inversely with
movements in interest rates. During periods of market uncertainty, the market
values of municipal obligations can become volatile. Certain investment grade
municipal securities in which the Funds may invest have speculative
characteristics, and the lower rated municipal securities in which Municipal
High Income Fund may invest are subject to greater risks of default and greater
volatility than higher rated securities. The market for lower rated municipal
securities may be thinner and less active than for higher rated securities.
Municipal High Income Fund may invest without limit in municipal securities that
pay interest that is an item of tax preference for purposes of the federal
alternative minimum tax. Each Fund's ability to invest more than 25% of its
total assets in municipal securities, the interest on which is paid from similar
types of projects, may increase the risk of a Fund investment. The concentration
of the investments of New York Tax-Free Income Fund and California Tax-Free
Income Fund in New York Obligations and California Obligations, respectively,
may subject those Funds to greater risks than an investment company that has a
broader range of investments. The States of New York and California and many of
their agencies and local governments have been experiencing, and continue to
experience, significant financial difficulties, and the credit standings of
those States and of certain local governments (including New York City) have
been, and could be further, reduced.

(1) Sales charge and exchange fee waivers are available for all shares and
    reduced sales charge purchase plans are available for Class A shares. The
    maximum 5% contingent deferred sales charge on Class B shares applies to
    redemptions during the first year after purchase; the charge generally
    declines by 1% annually thereafter, reaching zero after six years. See
    'Purchases.'
 
(2) Purchases of Class A shares of $1 million or more are not subject to an
    initial sales charge. A contingent deferred sales charge of 1% will be
    applied to most redemptions of such shares within one year of purchase. See
    'Purchases.'
 
(3) A contingent deferred sales charge of 0.75% will be applied to most
    redemptions of Class C shares within one year of purchase. See 'Purchases.'
 
(4) See 'Management' for additional information. In the case of New York

    Tax-Free Income Fund, all expenses are those that would have been
    experienced by that Fund for the fiscal year ended February 28, 1995 had
    Mitchell Hutchins and PaineWebber not waived a portion of their fees.

12b-1 distribution fees are asset-based sales charges. Long-term Class B and
Class C shareholders may pay more in direct and indirect sales charges
(including distribution fees) than the economic equivalent of the maximum
front-end sales charge permitted by the National Association of Securities
Dealers, Inc.

(1) Assumes deduction at the time of purchase of the maximum 4% initial sales
    charge.
 
(2) Assumes deduction at the time of redemption of the maximum applicable
    contingent deferred sales charge.
 
(3) Ten-year figures assume conversion of Class B shares to Class A shares at
    end of sixth year.
 
     This Example assumes that all dividends and other distributions are
reinvested and that the percentage amounts listed under Annual Fund Operating
Expenses remain the same in the years shown. The above tables and the assumption
in the Example of a 5% annual return are required by regulations of the
Securities and Exchange Commission ('SEC') applicable to all mutual funds; the
assumed 5% annual return is not a prediction of, and does not represent, the
projected or actual performance of any Class of the Funds' shares.
 
     THIS EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
EXPENSES, AND A FUND'S ACTUAL EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN. The
actual expenses attributable to each Class of a Fund's shares will depend upon,
among other things, the level of average net assets, the extent to which a Fund
incurs variable expenses, such as transfer agency costs and whether Mitchell
Hutchins and PaineWebber reimburse all or a portion of the Fund's expenses
and/or waive all or a portion of their advisory and other fees.

  * Annualized.

 ** During certain periods presented above, PaineWebber reimbursed the Fund for
    portions of its operating expenses. If such reimbursements had not been
    made, the annualized ratio of expenses to average net assets and the
    annualized ratio of net investment income to average net assets would have
    been 0.74% and 7.15%, respectively, for the year ended November 30, 1986 and
    1.26% and 6.56%, respectively, for the period from September 16, 1985 to
    November 30, 1985.

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

(2) Formerly Class D shares.

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

(2) Formerly Class D shares.

 ** During some of the periods presented above, PaineWebber/Mitchell Hutchins
    reimbursed the Fund for a portion of its operating expenses and/or waived
    all or a portion of its advisory and administration, distribution and
    transfer agency fees. If such reimbursements and waivers had not been made,
    for the Class A shares, the ratios of expenses to average net assets and the
    ratios of net investment income to average net assets would have been 1.16%
    and 5.39%, respectively, for the year ended February 28, 1994 and 1.29% and

    1991, 1990, 1989, and for the period from June 23, 1987 to February 29,
    1988. If such reimbursements and waivers had not been made for the Class B
    shares, the ratios of expenses to average net assets and the ratios of net
    investment income to average net assets would have been 1.90% and 4.61% for
    the year ended February 28, 1994 and 2.01% and 5.10%, and 1.98%* and 5.32%*,
    respectively, for the year ended February 28, 1993 and for the period from
    July 1, 1991 to February 29, 1992. If such reimbursements and waivers had
    not been made for the Class C shares, the ratios of expenses to average net
    assets and net investment income to average net assets would have been 1.64%
    and 4.85%, respectively, for the year ended February 28, 1994 and 1.69%* and
    4.97%*, respectively, for the period July 2, 1992 to February 28, 1993.

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

(2) Formerly Class D shares.

** During some of the periods presented above, PaineWebber/Mitchell Hutchins
    reimbursed the Fund for a portion of its operating expenses and/or waived
    all or a portion of its advisory and administration, distribution and
    transfer agency service fees. If such reimbursements and waivers had not
    been made, for the Class A shares the ratios of expenses to average net
    assets and the ratios of net investment income to average net assets would
    have been 1.26% and 5.13%, 1.25% and 4.63%, 1.47% and 4.94%, 1.53% and
    5.37%, 1.84% and 5.30%, 2.20% and 4.87%, and 3.04%* and 3.92%*,
    respectively, for the years ended February 28, 1995, 1994, 1993, for the
    year ended February 29, 1992, and for the years ended February 28, 1991 and
    1990, and for the period September 30, 1988 to February 28, 1989. If such
    reimbursements and waivers had not been made for the Class B shares, the
    ratios of expenses to average net assets and the ratios of net investment
    income to average net assets would have been 2.01% and 4.83%, 1.99% and
    3.86%, 2.19% and 4.13% and 2.20%* and 4.39%*, respectively, for the years
    ended February 28, 1995, 1994, 1993 and for the period from July 1, 1991 to
    February 29, 1992. If such reimbursements and waivers had not been made for
    the Class C shares, the ratios of expenses to average net assets and the
    ratios of net investment income to average net assets would have been 1.75%
    and 4.65%, 1.72% and 4.10%, and 1.83%* and 4.11%*, respectively, for the
    year ended February 28, 1995, 1994, for the period from July 2, 1992 to
    February 28, 1993.

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

(2) Formerly Class D shares.

                         DIFFERENCES AMONG THE CLASSES
 
The primary distinctions among the Classes of each Fund's shares lie in their
initial and contingent deferred sales charge structures and in their ongoing
expenses, including asset-based sales charges in the form of distribution fees.
These differences are summarized in the table below. Each Class has distinct
advantages and disadvantages for different investors, and investors may choose
the Class that best suits their circumstances and objectives.

</TABLE>
 
               FACTORS TO CONSIDER IN CHOOSING A CLASS OF SHARES
 
In deciding which Class of shares to purchase, investors should consider the
cost of sales charges together with the cost of the ongoing annual expenses
described below, as well as any other relevant facts and circumstances.

 
SALES CHARGES.  Class A shares are sold at net asset value plus an initial sales
charge of up to 4% of the public offering price. Because of this initial sales
charge, not all of a Class A shareholder's purchase price is invested in the
Fund. Class B shares are sold with no initial sales charge, but a contingent
deferred sales charge of up to 5% applies to most redemptions made within six
years of purchase. Class C shareholders pay no initial sales charges, although a
contingent deferred sales charge of 0.75% applies to most redemptions made
within the first year after purchase. Thus, the entire amount of a Class B or
Class C shareholder's purchase price is immediately invested in the Fund.

WAIVERS AND REDUCTIONS OF CLASS A SALES CHARGES.  Class A share purchases over
$100,000 and Class A share purchases made under a Fund's reduced sales charge
plan may be made at a reduced sales charge. In considering the combined cost of
sales charges and ongoing annual expenses, investors should take into account
any reduced sales charges on Class A shares for which they may be eligible.
 
The entire initial sales charge on Class A shares is waived for certain eligible
purchasers. Because Class A shares bear lower ongoing annual expenses than Class
B shares or Class C shares, investors eligible for complete waivers should
purchase Class A shares.
 
ONGOING ANNUAL EXPENSES.  Class A, B and C shares of each Fund pay an annual
12b-1 service fee of 0.25% of average daily net assets. Class B shares pay an
annual 12b-1 distribution fee of 0.75%, and Class C shares pay an annual 12b-1
distribution fee of 0.50%, of average daily net assets. Annual 12b-1
distribution fees are a form of asset-based sales charge. An investor should
consider both ongoing annual expenses and initial or contingent deferred sales
charges in estimating the costs of investing in the respective Classes of Fund
shares over various time periods.
 
For example, assuming a constant net asset value, the cumulative distribution
fees on a Fund's Class B and Class C shares would approximate the expense of the
4% maximum initial sales charge on the
 
                              --------------------
                               Prospectus Page 16
<PAGE>
             ------------------------------------------------------
 
                  PAINEWEBBER CALIFORNIA TAX-FREE INCOME FUND
                     PAINEWEBBER MUNICIPAL HIGH INCOME FUND
                   PAINEWEBBER NATIONAL TAX-FREE INCOME FUND
                   PAINEWEBBER NEW YORK TAX-FREE INCOME FUND
 
Class A shares if the shares were held for approximately 5 1/2 years in the case
of the Class B shares and approximately 8 years in the case of the Class C
shares. The cumulative distribution fees on the Class C shares would approximate
the cumulative distribution fees on the Class B shares if the shares were held
for 9 years. Thus, an investor who would be subject to the maximum initial sales
charge on Class A shares and who expects to hold a Fund's shares for less than 8
years generally should expect to pay the lowest cumulative expenses by
purchasing Class C shares.
 

The foregoing examples do not reflect, among other variables, the cost or
benefit of bearing sales charges or distribution fees at the time of purchase,
upon redemption or over time, nor can they reflect fluctuations in the net asset
value of Fund shares, which will affect the actual amount of expenses paid.
Expenses borne by Classes may differ slightly because of the allocation of other
Class-specific expenses. The 'Example of Effect of Fund Expenses' under
'Prospectus Summary' shows for each Fund the cumulative expenses an investor
would pay over time on a hypothetical investment in each Class of Fund shares,
assuming an annual return of 5%.
 
                               OTHER INFORMATION
 
PaineWebber investment executives may receive different levels of compensation
for selling one particular Class of shares rather than another. Investors should
understand that distribution fees and initial and contingent deferred sales
charges all are intended to compensate Mitchell Hutchins for distribution
services.

of the initial and contingent deferred sales charges, service fees and
distribution fees for Class A, B and C shares of each Fund. See also 'Conversion

                           INVESTMENT OBJECTIVES AND
                              PRIMARY INVESTMENTS
 
The investment objective of CALIFORNIA TAX-FREE INCOME FUND is to provide 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. The Fund seeks to invest 100% of its net assets in California
Obligations and, except under unusual market conditions, invests at least 80% of
its net assets in California Obligations that pay interest that is not an item
of tax preference for purposes of the federal alternative minimum tax ('AMT')
('AMT exempt interest'). See 'Other Investment Policies.'
 
The investment objective of NATIONAL TAX-FREE INCOME FUND is to provide high
current income exempt from federal income tax, consistent with the preservation
of capital and liquidity within the Fund's quality standards. The Fund seeks to
invest 100% of its net assets in municipal obligations with varying maturities.
Except under unusual market conditions, the Fund invests at least 80% of its net
assets in municipal obligations that pay AMT exempt interest. See 'Other
Investment Policies.'
 
The investment objective of MUNICIPAL HIGH INCOME FUND is to provide high
current income exempt from federal income tax. Except under unusual market
conditions, the Fund invests at least 80% of its net assets in municipal
obligations. The Fund may invest without limit in municipal obligations that pay
interest that is not AMT exempt interest. To date, the Fund has not purchased
such obligations.

 
The investment objective of NEW YORK TAX-FREE INCOME FUND is to provide high
current income exempt from federal income tax and from New York State and New
York City personal income taxes. The Fund seeks to invest 100% of its net assets
in New York Obligations and, except under unusual market conditions, invests at
least 80% of its net assets in New York Obligations that pay AMT exempt
interest. See 'Other Investment Policies.'

                     PAINEWEBBER MUNICIPAL HIGH INCOME FUND
                   PAINEWEBBER NATIONAL TAX-FREE INCOME FUND
                   PAINEWEBBER NEW YORK TAX-FREE INCOME FUND
 
National Tax-Free Income Fund and Municipal High Income Fund each may invest in
municipal obligations of issuers in any state that meet the particular Fund's
investment standards and pay interest that is exempt from federal income tax.
California Tax-Free Income Fund and New York Tax-Free Income Fund normally
invest only in municipal obligations that are California Obligations and New
York Obligations, respectively. Municipal obligations include, but are not
limited to, municipal bonds, floating rate and variable rate municipal
obligations, inverse floaters, participation interests in municipal bonds,
tax-exempt commercial paper, tender option bonds and short-term municipal notes.
Municipal bonds include industrial development bonds ('IDBs'), municipal lease
obligations and certificates of participation therein, put bonds and private
activity bonds ('PABs'). Each Fund also may invest in stand-by commitments, as
described in the Statement of Additional Information. No Fund may invest more
than 10% of its total assets in inverse floaters. Because most PABs do not pay
AMT exempt interest, none of California Tax-Free Income Fund, National Tax-Free
Income Fund and New York Tax-Free Income Fund will invest more than 20% of its
net assets in such PABs, except under unusual market conditions. The principal
municipal obligations in which the Funds invest are described in Appendix A to
this Prospectus.
 
There can be no assurance that any Fund will achieve its investment objective.
Each Fund's net asset value fluctuates based upon changes in the value of its
portfolio securities. Each Fund's investment objective and certain investment
limitations described in the Statement of Additional Information are fundamental
policies that may not be changed without shareholder approval. In addition,
California Tax-Free Income Fund's policy of investing at least 80% of its net
assets in California Obligations that pay AMT exempt interest, National Tax-Free
Income Fund's policy of investing at least 80% of its net assets in municipal
obligations that pay AMT exempt interest, Municipal High Income Fund's policy of
investing at least 80% of its net assets in municipal obligations and New York
Tax-Free Income Fund's policy of investing at least 80% of its net assets in New
York Obligations that pay AMT exempt interest, may not be changed without
shareholder approval. All other investment policies may be changed without
shareholder approval by the appropriate Trust's board of trustees.

                           OTHER INVESTMENT POLICIES

                                AND RISK FACTORS
 
CREDIT QUALITY.  Each Fund invests only in municipal securities that present
acceptable credit risks in the judgment of Mitchell Hutchins and, with the
exception of Municipal High Income Fund, that at the time of purchase are rated
at least Baa or MIG-2 by Moody's Investors Service, Inc. ('Moody's'), BBB or
SP-2 by Standard & Poor's, a division of The McGraw Hill Companies, Inc.,
('S&P'), have been assigned an equivalent rating by another nationally
recognized statistical rating organization ('NRSRO') or, if unrated, are
determined by Mitchell Hutchins to be of comparable quality. Except as described
below, Municipal High Income Fund invests at least 65% and seeks to invest 100%
of its net assets in medium and lower grade municipal obligations. Medium grade
municipal obligations are of investment grade quality and are rated A, Baa or
MIG-2 by Moody's, A, BBB or SP-2 by S&P, have been assigned an equivalent rating
from another NRSRO or, if unrated, are determined by Mitchell Hutchins to be of
comparable quality. Lower grade municipal obligations are those rated Ba, B,
MIG-3 or MIG-4 by Moody's, BB, B or SP-3 by S&P, have an equivalent rating from
another NRSRO or, if unrated, are determined by Mitchell Hutchins to be of
comparable quality. Mitchell Hutchins does not intend during the coming year to
invest Municipal High Income Fund's assets in securities rated lower than B by
Moody's or S&P at the time of purchase. Medium and lower grade municipal
securities generally offer a higher current yield than higher rated securities,
but also carry greater investment risk. See 'Yield and Risk Factors' and 'Risks
of Lower Rated Securities.'
 
Municipal High Income Fund also may invest up to 35%, and temporarily may invest
more than 35%, of its net assets in higher grade municipal securities if
Mitchell Hutchins considers such a strategy to be appropriate. For example,
Municipal High Income Fund might make such investments when the difference in
returns between different grades of municipal securities is very narrow,
Mitchell Hutchins expects interest rates to rise or the availability of medium
and lower grade securities is limited. Investments in higher grade securities
may result in lower yield than if the Fund were fully invested in medium and
lower grade issues.

During the 1995 fiscal year, Municipal High Income Fund had 100% of its average
annual net assets in municipal securities that received a rating from Moody's or
S&P. Municipal High Income Fund had the following percentages of its average
annual net assets invested in rated securities: AAA/Aaa (including cash items
and repurchase agreements)-- 9.9%, AA/Aa--9.2%, A/A--24.7%, BBB/Baa--43.8%,
BB/Ba--9.7%, B/B--2.7%, CCC/Caa--0%, CC/Ca-- 0%, C/C--0%, and D--0%. Municipal
securities that received different ratings from Moody's and S&P were assigned to
the lower rating category. It should be noted that this information reflects the
average composition of the Fund's assets during the fiscal year ended February

28, 1995, and is not necessarily representative of the Fund's assets at the end
of that fiscal year, the current fiscal year or any other time in the future.
 
Moody's and S&P may assign equivalent ratings to those described above for
specific categories of securities. See the Statement of Additional Information
and Appendix B to this Prospectus for further information about Moody's and S&P
ratings.
 
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. In when-issued or delayed delivery transactions, delivery of the
securities occurs beyond normal settlement periods, but a Fund would not pay for
such securities or start earning interest on them until they are delivered.
However, when a Fund purchases securities on a when-issued or delayed delivery
basis, it immediately assumes the risks of ownership, including the risk of
price fluctuation. Failure by a counter party to deliver a security purchased on
a when-issued or delayed delivery basis may result in the Fund's incurring a
loss or missing an opportunity to make an alternative investment. Depending on
market conditions, a Fund's when-issued and delayed delivery purchase
commitments could cause its net asset value per share to be more volatile,
because such securities may increase the amount by which the Fund's total
assets, including the value of when-issued and delayed delivery securities held
by the Fund, exceed its net assets.
 
YIELD AND RISK FACTORS.  The yield of a municipal security depends on a variety
of factors, including general municipal and fixed-income security market
conditions, the financial condition of the issuer, the size of the particular
offering, the maturity, credit quality and rating of the issue and expectations
regarding changes in tax rates. Generally, the longer the maturity of a
municipal security, the higher the rate of interest paid and the greater the
volatility. Further, if general market interest rates are increasing, the prices
of municipal obligations ordinarily will decrease and, if rates decrease, the
opposite generally will be true. During periods of market uncertainty, the
market values of fixed income securities can become volatile. Each Fund may
invest in municipal securities with a broad range of maturities, based on
Mitchell Hutchins' judgment of current and future market conditions as well as
other factors, such as the Fund's liquidity needs. Accordingly, the average
weighted maturity of each Fund's portfolio may vary.
 
Ratings of municipal securities represent the NRSROs' opinions regarding their
quality, are not a guarantee of quality and may be reduced after a Fund has
acquired the security. Mitchell Hutchins will consider such an event in deciding
whether a Fund should continue to hold the security but is not required to
dispose of it. However, in the event that, due to a downgrade of one or more
debt securities, an amount in excess of 5% of the net assets of California
Tax-Free Income Fund, National Tax-Free Income Fund or New York Tax-Free Income
Fund is held in securities rated below investment grade and comparable unrated
securities, Mitchell Hutchins will engage in an orderly disposition of these
securities to the extent necessary to ensure that the Fund's holdings of these
securities do not exceed 5% of its net assets. Credit ratings attempt to
evaluate the safety of principal and interest payments and do not reflect an
assessment of the volatility of the security's market value or the liquidity of
an investment in the security. Also, NRSROs may fail to make timely changes in
credit ratings in response to subsequent events, so that an issuer's current

financial condition may be better or worse than the rating indicates. Securities
rated BBB by S&P or Baa by Moody's are investment grade, but Moody's considers
securities rated Baa to have speculative characteristics. Changes in economic
conditions or other circumstances are more likely to lead to a weakened capacity
for such securities to make principal and interest payments than is the case for
higher grade municipal securities. In addition, future federal, state and local
laws may adversely affect the tax-exempt status of interest on a Fund's
portfolio securities or of the exempt-interest dividends paid

                  PAINEWEBBER CALIFORNIA TAX-FREE INCOME FUND
                     PAINEWEBBER MUNICIPAL HIGH INCOME FUND

by a Fund, extend the time for payment of principal or interest or otherwise
constrain enforcement of such obligations. Opinions relating to the validity of
municipal securities and the tax-exempt status of interest thereon are rendered
by the issuer's bond counsel at the time of issuance; Mitchell Hutchins will
rely on such opinions without independent investigation.
 
Municipal High Income Fund and New York Tax-Free Income Fund are each
'non-diversified,' as that term is defined in the Investment Company Act of 1940
('1940 Act'). Each intends to continue to qualify as a 'regulated investment
company' for federal income tax purposes. See 'Dividends and Taxes.' This means,
in general, that more than 5% of each Fund's total assets may be invested in
securities of one issuer, but only if, at the close of each quarter of the
Fund's taxable year, the aggregate amount of such holdings does not exceed 50%
of the value of its total assets and no more than 25% of the value of its total
assets is invested in the securities of a single issuer. Although Mitchell
Hutchins anticipates that normally each Fund's portfolio will include the
securities of a number of different issuers, each of these Funds may be subject
to greater risk with respect to its portfolio securities than a 'diversified'
investment company, because changes in the financial condition or market
assessment of a single issuer may cause greater fluctuation in the Fund's yield
and the net asset value of Fund shares.
 
Each Fund may invest more than 25% of its total assets in municipal securities
that are related in such a way that an economic, business or political
development or change affecting one such security also might affect the other
securities, such as securities the interest on which is paid from revenues of
similar types of projects. The Funds may be subject to greater risk than other
funds that do not follow this practice.
 
RISKS OF LOWER RATED SECURITIES.  Municipal High Income Fund's policy of
investing a portion of its assets in lower rated securities entails greater
risks than those associated with investment in higher rated securities.
Municipal securities rated below investment grade are deemed by Moody's and S&P
to be predominantly speculative with respect to the issuer's capacity to pay
interest and repay principal and may involve major risk exposure to adverse

conditions. Such securities are commonly referred to as municipal 'junk bonds.'
Lower rated municipal securities generally offer a higher current yield than
higher grade issues, but they involve higher risks, in that they are especially
subject to adverse changes in general economic conditions, in economic
conditions in the issuer's geographic area and in the industries or activities
in which the issuer is engaged, to changes in the financial condition of the
issuers and to price fluctuations in response to changes in interest rates.
During periods of economic downturn or rising interest rates, municipal issuers
may experience financial stress which could adversely affect their ability to
make payments of principal and interest and increase the possibility of default.
 
In addition, medium and lower grade municipal securities are frequently traded
only in markets where the number of potential purchasers and sellers, if any, is
limited. This factor may limit Municipal High Income Fund's ability to acquire
such securities and also may limit the Fund's ability to sell such securities at
their fair value in response to changes in the economy or the financial markets.
This may be especially true of unrated securities. Although unrated securities
are not necessarily of lower quality than rated securities, the market for rated
securities generally is broader than that for unrated issues. Adverse publicity
and investor perceptions, whether or not based on fundamental analysis, may also
decrease the values and liquidity of lower rated securities, especially in a
thinly traded market.
 
Although Mitchell Hutchins will attempt to minimize the speculative risks
associated with investments in lower rated securities through credit analysis
and monitoring and attention to current trends in interest rates and other
factors, investors should carefully review the investment objective and policies
of Municipal High Income Fund and consider their ability to assume the
investment risks involved before making an investment.
 
RISKS OF CALIFORNIA OBLIGATIONS.  California Tax-Free Income Fund's investment
concentration in California Obligations involves greater risks than if it
selected its investments from a broader geographic region. The Fund's yield and
net asset value per share can be affected by political and economic developments
within the State of California ('California'), and by the financial condition of
California, its public authorities and political subdivisions. California
suffered a severe recession between 1990-1993, resulting in significant revenue

shortfalls for both the State and local governments, and increased social
service expenses. During this period, the State of California's credit ratings
were downgraded. Since the start of 1994, the State economy has been in a steady
recovery, and the State's fiscal condition has improved. State assistance to
local governments has been reduced since 1992, and a number of local agencies,
especially counties, continue to face serious budgetary constraints.

 
In the past, California voters have passed amendments to the California
Constitution and other measures that limit the taxing and spending authority of
California governmental entities and future voter initiatives could result in
adverse consequences affecting California Obligations. These factors, among
others (including the outcome of related pending litigation), could reduce the
credit standing of certain issuers of California Obligations. A more detailed
discussion of the risks of investing in California Obligations is included in
the Statement of Additional Information.
 
RISKS OF NEW YORK OBLIGATIONS.  New York Tax-Free Income Fund's investment
concentration in New York Obligations involves greater risks than if it invested
in the securities of a broader range of issuers. The Fund's yield and the value
of its portfolio can be affected by political and economic developments within
the State of New York ('State'), and by the financial condition of the State,
its public authorities and political subdivisions, particularly the City of New
York ('City'). Although the State reduced its accumulated General Fund deficits
and experienced operating surpluses in fiscal year ('FY') 1991-92 through
FY1993-94, it continues to experience substantial financial difficulties related
to the recent recession resulting in, among other things, reductions in General
Fund receipts. An estimated budget gap of approximately $4.7 billion is
projected for FY1995-96, unless numerous and substantial corrective measures are
successfully implemented. The City (which is constrained in its fiscal
flexibility by an already heavy local tax burden, urgent social needs and its
extensive and deteriorating infrastructure) and most suburban county governments
are also experiencing serious fiscal problems related to the recessionary
performance of the regional economy, which has caused substantial, broad-based
and recurring revenue shortfalls. The credit standings of the State and the City
have been, and could be further, reduced; and their ability to provide
assistance to its public authorities and political subdivisions has been, and
could be further, impaired. A more detailed discussion of the risks of investing
in New York Obligations is included in the Statement of Additional Information.
 
OTHER INVESTMENT POLICIES.  During unusual market conditions, including when in
the opinion of Mitchell Hutchins there are insufficient suitable municipal
obligations available, each of California Tax-Free Income Fund, National
Tax-Free Income Fund and New York Tax-Free Income Fund, for defensive purposes,
temporarily may invest more than 20% of its net assets in other municipal
obligations. For this purpose, 'suitable municipal obligations' means, in the
case of California Tax-Free Income Fund, California Obligations that pay AMT
exempt interest, in the case of National Tax-Free, municipal obligations that
pay AMT exempt interest and, in the case of New York Tax-Free Income Fund, New
York Obligations that pay AMT exempt interest. 'Other municipal obligations'
means municipal obligations that pay interest that is exempt from federal income
tax but is subject to California personal income tax (in the case of California
Tax-Free Income Fund), New York personal income tax (in the case of New York
Tax-Free Income Fund) or is not AMT exempt interest.
 
Each Fund expects that under normal circumstances it will maintain needed
liquidity through the purchase of short-term municipal securities, including
tender option bonds. However, when Mitchell Hutchins believes unusual
circumstances warrant a defensive position, including when in the opinion of
Mitchell Hutchins no suitable municipal obligations are available, each Fund
temporarily and without percentage limit may hold cash and invest in taxable

money market instruments, including repurchase agreements. Interest earned from
such taxable investments will be taxable to investors as ordinary income when
distributed. If a Fund holds cash, the cash would not earn income and would
reduce the Fund's yield.
 
Each Fund is authorized to engage in certain option income strategies and to use
options and futures in hedging strategies, all of which may generate taxable
income. None of the Funds have engaged in these strategies in the past or have
any intention of so doing during the coming year. A discussion of these
strategies is included in the Statement of Additional Information. Each Fund may
borrow money for emergency or temporary purposes, but not in excess

of 10% of its total assets. No Fund will invest more than 10% of its net assets
in illiquid securities. The term 'illiquid securities' for this purpose means
securities that cannot be disposed of within seven days in the ordinary course
of business at approximately the amount at which the Fund has valued the
securities and includes, among other things, repurchase agreements maturing in
more than seven days and municipal lease obligations (including certificates of
participation) other than those Mitchell Hutchins has determined are liquid
pursuant to guidelines established by the appropriate Trust's board of trustees.

                                   PURCHASES
- --------------------------------------------------------------------------------
 
GENERAL.  Class A shares are sold to investors subject to an initial sales
charge. Class B shares are sold without an initial sales charge but are subject
to higher ongoing expenses than Class A shares and a contingent deferred sales
charge payable upon most redemptions. Class B shares automatically convert to
Class A shares approximately six years after issuance. Class C shares are sold
without an initial sales charge but are subject to higher ongoing expenses than
Class A shares and a contingent deferred sales charge of 0.75% payable on most
redemptions made within one year of purchase. Class C shares do not convert into
another Class. See 'Flexible Pricing System' and 'Conversion of Class B Shares.'
 
Shares of the Funds are available through PaineWebber and its correspondent
firms or, for shareholders who are not PaineWebber clients, through the Transfer
Agent. Investors may contact a local PaineWebber office to open an account. The
minimum initial investment for each Fund is $1,000 and the minimum for
additional purchases is $100. These minimums may be waived or reduced for
investments by employees of PaineWebber or its affiliates and participants in a
Fund's automatic investment plan. Purchase orders will be priced at the net
asset value per share next determined (see 'Valuation of Shares') after the
order is received by PaineWebber's New York City offices or by the Transfer

Agent, plus any applicable sales charge for Class A shares. Each Fund and
Mitchell Hutchins reserve the right to reject any purchase order and to suspend
the offering of Fund shares for a period of time.
 
When placing purchase orders, investors should specify whether the order is for
Class A, Class B or Class C shares. All share purchase orders that fail to
specify a Class will automatically be invested in Class A shares.
 
PURCHASES THROUGH PAINEWEBBER OR CORRESPONDENT FIRMS.  Purchases through
PaineWebber investment executives or correspondent firms may be made in person
or by mail, telephone or wire; the minimum wire purchase is $1 million.
Investment executives and correspondent firms are responsible for transmitting
purchase orders to PaineWebber's New York City offices promptly. Investors may
pay for purchases with checks drawn on U.S. banks or with funds held in
brokerage accounts at PaineWebber or its correspondent firms. Payment is due on
the third Business Day after the order is received at PaineWebber's New York
City offices. A 'Business Day' is any day, Monday through Friday, on which the
New York Stock Exchange, Inc. ('NYSE') is open for business.
 
PURCHASES THROUGH THE TRANSFER AGENT. Investors who are not PaineWebber clients
may purchase shares of the Funds through the Transfer Agent. Shares of a Fund
may be purchased, and an account with the Fund established, by completing and
signing the purchase application at the end of this Prospectus and mailing it,
together with a check to cover the purchase, to the Transfer Agent: PFPC Inc.,
Attn: PaineWebber Mutual Funds, P.O. Box 8950, Wilmington, Delaware 19899.
Subsequent investments need not be accompanied by an application.
 
INITIAL SALES CHARGE--CLASS A SHARES.  The public offering price of Class A

(1) Mitchell Hutchins pays compensation to PaineWebber out of its own resources.
    Most redemptions of these shares within one year of purchase will be subject
    to a contingent deferred sales charge of 1%. See 'Contingent Deferred Sales
    Charge--Class A Shares.'
 
Mitchell Hutchins may at times agree to reallow a higher discount to
PaineWebber, as primary dealer for each Fund's shares, than those shown above.
To the extent PaineWebber or any dealer receives 90% or more of the sales
charge, it may be deemed an 'underwriter' under the Securities Act of 1933.
 
REDUCED SALES CHARGE PLANS--CLASS A SHARES. If an investor or eligible group of
related Fund investors purchases Class A shares of a Fund concurrently with
Class A shares of other PaineWebber mutual funds, the purchases may be combined
to take advantage of the reduced sales charge applicable to larger purchases. In
addition, the right of accumulation permits a Fund investor or eligible group of
related Fund investors to pay the lower sales charge applicable to larger
purchases by basing the sales charge on the dollar amount of Class A shares
currently being purchased, plus the net asset value of the investor's or group's
total existing Class A shareholdings in other PaineWebber mutual funds.
 
An 'eligible group of related Fund investors' includes an individual, the
individual's spouse, parents and children, the individual's individual
retirement account ('IRA'), certain companies controlled by the individual and
employee benefit plans of those companies, and trusts or Uniform Gifts to Minors
Act/Uniform Transfers to Minors Act accounts created by the individual or

eligible group of individuals for the benefit of the individual and/or the
individual's spouse, parents or children. The term also includes a group of
related employers and one or more qualified retirement plans of such employers.
For more information, an investor should consult the Statement of Additional
Information or contact a PaineWebber investment executive or correspondent 
firm or the Transfer Agent.
 
SALES CHARGE WAIVERS--CLASS A SHARES.  Class A shares are available without a
sales charge through exchanges for Class A shares of most other PaineWebber
mutual funds. See 'Exchanges.' In addition, Class A shares may be purchased
without a sales charge, and exchanges of any Class of shares may be made without
the $5.00 exchange fee, by employees, directors and officers of PaineWebber or
its affiliates, directors or trustees and officers of any PaineWebber mutual
funds, their spouses, parents and children and advisory clients of Mitchell
Hutchins.
 
Class A shares also may be purchased without a sales charge if the purchase is
made through a PaineWebber investment executive who formerly was employed as a
broker with another firm registered as a broker-dealer with the SEC, provided
(1) the purchaser was the investment executive's client at the competing
brokerage firm, (2) within 90 days of the purchase of Class A shares the
purchaser redeemed shares of one or more mutual funds for which that competing
firm or its affiliates was principal underwriter, provided the purchaser either
paid a sales charge to invest in those funds, paid a contingent deferred sales
charge upon redemption or held shares of those funds for the period required not
to pay the otherwise applicable contingent deferred sales charge and (3) the
total amount of shares of all PaineWebber funds purchased under this sales
charge waiver does not exceed the amount of the purchaser's redemption proceeds
from the competing firm's funds. To take advantage of this waiver, an investor
must provide satisfactory evidence that all the above-noted conditions are met.
Qualifying investors should contact their PaineWebber investment executives for
more information.
 
Certificate holders of certain municipal bond trusts ('MBTs') sponsored by
PaineWebber may acquire Class A shares of the Funds without regard to the
minimum investment requirements and without sales charges by electing to have
distributions from their MBT investment automatically invested in Class A
shares. In addition, certificate holders who have had past MBT distributions
reinvested through the MBT reinvestment program may, upon redemption of those
reinvestment units, invest the full amount of all redemption proceeds in shares
of a Fund, also without sales charges and without regard to minimum investment
requirements.

CONTINGENT DEFERRED SALES CHARGE--CLASS A SHARES.  Class A shares purchased

without an initial sales charge due to the sales charge waiver for purchases of
$1 million or more and held less than one year are subject to a contingent
deferred sales charge upon redemption equal to 1% of the lower of (a) the net
asset value of the shares at the time of purchase or (b) the net asset value of
the shares at the time of redemption. The holding period of Class A shares
acquired through an exchange with another PaineWebber mutual fund is calculated
from the date the Class A shares of the other PaineWebber mutual fund were
initially purchased without a sales charge, and Class A shares acquired through
an exchange will be considered to represent, as applicable, dividend and capital
gain distribution reinvestments in such other funds. Redemption order will be
determined as described for Class B shares (see 'Contingent Deferred Sales
Charge-- Class B Shares'). Class A shares held one year or longer and Class A
shares acquired through reinvestment of dividends or capital gains distributions
are not subject to this contingent deferred sales charge. The contingent
deferred sales charge is waived for exchanges, as described below, and for most
redemptions in connection with the systematic withdrawal plan. THIS CONTINGENT
DEFERRED SALES CHARGE DOES NOT APPLY TO REDEMPTIONS OF CLASS A SHARES PURCHASED
PRIOR TO NOVEMBER 10, 1995. For federal income tax purposes, the amount of the
contingent deferred sales charge will reduce the gain or increase the loss, as
the case may be, realized on redemption. The amount of any contingent deferred
sales charge will be paid to Mitchell Hutchins.
 
CONTINGENT DEFERRED SALES CHARGE--CLASS B SHARES.  The public offering price of
the Class B shares is the next determined net asset value, and no initial sales
charge is imposed. A contingent deferred sales charge, however, is imposed upon
most redemptions of Class B shares.
 
The maximum contingent deferred sales charge for Class B shares equals 5% of
lower of (1) the net asset value of the shares at the time of purchase or (2)
the net asset value of the shares at the time of redemption. Class B shares held
six years or longer and Class B shares acquired through reinvestment of
dividends or capital gains distributions are not subject to the contingent
deferred sales charge. The following table shows the contingent deferred sales
charge percentages charged in each year following purchase:

In determining the applicability and rate of any contingent deferred sales
charge, it will be assumed that a redemption is made first of Class B shares

representing the reinvestment of dividends and capital gains distributions and
then of other shares held by the shareholder for the longest period of time. The
holding period of Class B shares acquired through an exchange with another
PaineWebber mutual fund will be calculated from the date that the Class B shares
were initially acquired in one of the other PaineWebber mutual funds, and Class
B shares acquired through an exchange will be considered to represent, as
applicable, dividend and capital gain distribution reinvestments in such other
funds. This will result in any contingent deferred sales charge being imposed at
the lowest possible rate. For federal income tax purposes, the amount of the
contingent deferred sales charge will reduce the gain or increase the loss, as
the case may be, realized on the redemption. The amount of any contingent
deferred sales charge will be paid to Mitchell Hutchins.
 
SALES CHARGE WAIVERS--CLASS B SHARES.  The contingent deferred sales charge will
be waived for exchanges, as described below, and for most redemptions in
connection with each Fund's systematic withdrawal plan. In addition, the
contingent deferred sales charge will be waived where a total or partial
redemption is made within one year of the death of the shareholder. The
contingent deferred sales charge waiver is available where the decedent is
either the sole shareholder or owns the shares with his or her spouse as a joint
tenant with right of survivorship. This waiver applies only to redemption of
shares held at the time of death.
 
Contingent deferred sales charge waivers will be granted subject to confirmation

the next determined net asset value. No initial sales charge is imposed.
 
CONTINGENT DEFERRED SALES CHARGE--CLASS C SHARES.  Class C shares held less than
one year will be subject to a contingent deferred sales charge on redemptions in
an amount equal to 1% of the lower of (a) the net asset value of the shares at
the time of purchase or (b) the net asset value of the shares at the time of
redemption. The holding period of Class C shares acquired through an exchange
with another PaineWebber mutual fund is calculated from the date the Class C
shares of the other PaineWebber mutual fund were initially purchased without a
sales charge, and Class C shares acquired through an exchange will be considered
to represent, as applicable, dividend and capital gain distribution
reinvestments in such other funds. Redemption order will be determined as
described for Class B shares (see 'Contingent Deferred Sales Charge--Class B

Shares'). Redemptions of Class C shares acquired through an exchange and held
less than one year will be subject to the same contingent deferred sales charge
that would have been imposed on Class C shares of the PaineWebber mutual fund
originally purchased that were subsequently exchanged into Class C shares of the
Fund. Class C shares held one year or longer and Class C shares acquired through
reinvestment of dividends or capital gains distributions are not subject to this
contingent deferred sales charge. The contingent deferred sales charge is waived
for exchanges, as described below, and for most redemptions in connection with
the systematic withdrawal plan. THIS CONTINGENT DEFERRED SALES CHARGE DOES NOT
APPLY TO REDEMPTIONS OF CLASS C SHARES PURCHASED PRIOR TO NOVEMBER 10, 1995. For
federal income tax purposes, the amount of the contingent deferred sales charge
will reduce the gain or increase the loss, as the case may be, realized on
redemption. The amount of any contingent deferred sales charge will be paid to
Mitchell Hutchins.

                                   EXCHANGES
- --------------------------------------------------------------------------------
 
Shares of each Fund may be exchanged for shares of the corresponding Class of
other PaineWebber mutual funds or may be acquired through an exchange of shares
of the corresponding Class of those funds. No initial sales charge is imposed on
the shares being acquired, and no contingent deferred sales charge is imposed on
the shares being disposed of, through an exchange. However, contingent deferred
sales charges may apply to redemptions of shares of PaineWebber mutual funds
acquired through an exchange. A $5.00 exchange fee is charged for each exchange,
and exchanges may be subject to minimum investment requirements of the fund into
which exchanges are made.

PaineWebber clients must place exchange orders through their PaineWebber
investment executives or correspondent firms unless the shares to be exchanged
are held in certificate form. Shareholders who are not PaineWebber clients or
who hold their shares in certificate form must place exchange orders in writing
with the Transfer Agent: PFPC Inc., Attn: PaineWebber Mutual Funds, P.O. Box
8950, Wilmington, Delaware 19899. All exchanges will be effected based on the
relative net asset values per share next determined after the exchange order is
received at PaineWebber's New York City offices or by the Transfer Agent. See
'Valuation of Shares.' Shares of the Funds purchased through PaineWebber or its
correspondent firms may be exchanged only after the settlement date has passed
and payment for such shares has been made.
 
OTHER EXCHANGE INFORMATION.  This exchange privilege may be modified or
terminated at any time, upon at least 60 days' notice when such notice is
required by SEC rules. This exchange privilege is available only in those
jurisdictions where the sale of the PaineWebber mutual fund shares to be
acquired through such exchange may be legally made. Before making any exchange,
shareholders should contact their PaineWebber investment executives or
correspondent firms or the Transfer Agent to obtain more information and
prospectuses of the PaineWebber mutual funds to be acquired through the
exchange.
 
- --------------------------------------------------------------------------------
                                  REDEMPTIONS
- --------------------------------------------------------------------------------
 
Fund shares may be redeemed at their net asset value (subject to any applicable
contingent deferred sales charge) and redemption proceeds will be paid after
receipt of a redemption request as described below. PaineWebber clients may
redeem non-certificated shares through PaineWebber or its correspondent firms;
all other shareholders must redeem through the Transfer Agent. If a redeeming
shareholder owns shares of more than one Class, the shares will be redeemed in
the following order unless the shareholder specifically requests otherwise:
Class A shares, then Class C shares, and finally Class B shares.
 
REDEMPTION THROUGH PAINEWEBBER OR CORRESPONDENT FIRMS.  PaineWebber clients may
submit redemption requests to their investment executives or correspondent firms
in person or by telephone, mail or wire. As each Fund's agent, PaineWebber may
honor a redemption request by repurchasing Fund shares from a redeeming
shareholder at the shares' net asset value next determined after receipt of the
request by PaineWebber's New York City offices. Within three Business Days after
receipt of the request, repurchase proceeds (less any applicable contingent
deferred sales charge) will be paid by check or credited to the shareholder's
brokerage account at the election of the shareholder. PaineWebber investment

executives and correspondent firms are responsible for promptly forwarding
redemption re quests to PaineWebber's New York City offices.
 
PaineWebber reserves the right not to honor any redemption request, in which
case PaineWebber promptly will forward the request to the Transfer Agent for
treatment as described below.
 
REDEMPTION THROUGH THE TRANSFER AGENT. Fund shareholders who are not PaineWebber
clients or who wish to redeem certificated shares must redeem their shares
through the Transfer Agent by mail; other shareholders also may redeem Fund
shares through the Transfer Agent. Shareholders should mail redemption requests
directly to the Transfer Agent: PFPC Inc., Attn: PaineWebber Mutual Funds, P.O.
Box 8950, Wilmington, Delaware 19899. A redemption request will be executed at
the net asset value next computed after it is received in 'good order' and
redemption proceeds will be paid within seven days of receipt of the request.
'Good order' means that the request must be accompanied by the following: (1) a
letter of instruction or a stock assignment specifying the number of shares or
amount of investment to be redeemed (or that all shares credited to a Fund
account be redeemed), signed by all registered owners of the shares in the exact
names in which they are registered, (2) a guarantee of the signature of each
registered owner by an eligible institution

acceptable to the Transfer Agent and in accordance with SEC rules, such as a
commercial bank, trust company or member of a recognized stock exchange, (3)
other supporting legal documents for estates, trusts, guardianships,
custodianships, partnerships and corporations and (4) duly endorsed share
certificates, if any. Shareholders are responsible for ensuring that a request
for redemption is received in 'good order.'
 
ADDITIONAL INFORMATION ON REDEMPTIONS.  A shareholder who holds non-certificated
Fund shares may have redemption proceeds of $1 million or more wired to the
shareholder's PaineWebber brokerage account or a commercial bank account
designated by the shareholder. Questions about this option, or redemption
requirements generally, should be referred to the shareholder's PaineWebber
investment executive or correspondent firm, or to the Transfer Agent if the
shares are not held in a PaineWebber brokerage account. If a shareholder
requests redemption of shares which were purchased recently, a Fund may delay
payment until it is assured that good payment has been received. In the case of
purchases by check, this can take up to 15 days.
 
Because the Funds incur certain fixed costs in maintaining shareholder accounts,
each Fund reserves the right to redeem all Fund shares in any shareholder
account of less than $500 net asset value. If a Fund elects to do so, it will
notify the shareholder and provide the shareholder the opportunity to increase

the amount invested to $500 or more within 60 days of the notice. A Fund will
not redeem accounts that fall below $500 solely as a result of a reduction in
net asset value per share.
 
Shareholders who have redeemed Class A shares may reinstate their Fund account
without a sales charge up to the dollar amount redeemed by purchasing Class A
shares of the same Fund within 365 days of the redemption. To take advantage of
this reinstatement privilege, shareholders must notify their PaineWebber
investment executive or correspondent firm at the time the privilege is
exercised.
 
- --------------------------------------------------------------------------------
                          CONVERSION OF CLASS B SHARES
- --------------------------------------------------------------------------------
 
A shareholder's Class B shares will automatically convert to Class A shares in
the same Fund approximately six years after the date of issuance, together with
a pro rata portion of all Class B shares representing dividends and other
distributions paid in additional Class B shares. The Class B shares so converted
will no longer be subject to the higher expenses borne by Class B shares. The
conversion will be effected at the relative net asset values per share of the
two Classes on the first Business Day of the month in which the sixth
anniversary of the issuance of the Class B shares occurs. See 'Valuation of
Shares.' If a shareholder effects one or more exchanges among Class B shares of
the PaineWebber mutual funds during the six-year period, the holding periods for
the shares so exchanged will be counted toward the six-year period.

                         OTHER SERVICES AND INFORMATION

Investors interested in the services described below should consult their
PaineWebber investment executives or correspondent firms or call the Transfer
Agent toll-free at 1-800-647-1568.
 
AUTOMATIC INVESTMENT PLAN.  Shareholders may purchase shares of the Funds
through an automatic investment plan, under which an amount specified by the
shareholder of $50 or more each month will be sent to the Transfer Agent from
the shareholder's bank for investment in a Fund. In addition to
 
                              --------------------
                               Prospectus Page 27

                  PAINEWEBBER CALIFORNIA TAX-FREE INCOME FUND
                     PAINEWEBBER MUNICIPAL HIGH INCOME FUND
                   PAINEWEBBER NATIONAL TAX-FREE INCOME FUND
                   PAINEWEBBER NEW YORK TAX-FREE INCOME FUND
 
providing a convenient and disciplined manner of investing, participation in the
automatic investment plan enables the investor to use the technique of 'dollar
cost averaging.' When under the plan a shareholder invests the same dollar
amount each month, the shareholder will purchase more shares when a Fund's net

asset value per share is low and fewer shares when the net asset value per share
is high. Using this technique, a shareholder's average purchase price per share
over any given period will be lower than if the shareholder purchased a fixed
number of shares on a monthly basis during the period. Of course, investing
through the automatic investment plan does not assure a profit or protect
against loss in declining markets. Additionally, since the automatic investment
plan involves continuous investing regardless of price levels, an investor
should consider his or her financial ability to continue purchases through
periods of low price levels.
 
SYSTEMATIC WITHDRAWAL PLAN.  Shareholders who own non-certificated Class A or
Class C shares with a value of $5,000 or more or Class B shares with a value of
$20,000 or more may have PaineWebber redeem a portion of their shares monthly,
quarterly or semi-annually under the systematic withdrawal plan. Shareholders
who participate in the systematic withdrawal plan must elect to have all
dividends reinvested in additional shares of the same Class. The minimum amount
for all withdrawals of Class A or Class C shares is $100, and minimum monthly,
quarterly and semi-annual withdrawal amounts for Class B shares are $200, $400
and $600, respectively. Quarterly withdrawals are made in March, June, September
and December, and semi-annual withdrawals are made in June and December.
Provided that the shareholder does not withdraw an amount exceeding 12% (in the
first year after purchase for Class A and Class C shares, annually for Class B
shares) of his or her 'Initial Account Balance,' a term that means the value of
the Fund account at the time the shareholder elects to participate in the
systematic withdrawal plan, no contingent deferred sales charge is imposed on
such withdrawals. A shareholder's participation in the systematic withdrawal
plan will terminate automatically if the Initial Account Balance (plus the net
asset value on the date of purchase of Fund shares acquired after the election
to participate in the systematic withdrawal plan), less aggregate redemptions
made other than pursuant to the systematic withdrawal plan, is less than $5,000
for Class A and Class C shareholders or $20,000 for Class B shareholders.
Purchases of additional shares of a Fund concurrent with withdrawals are
ordinarily disadvantageous to shareholders because of tax liabilities and, for
Class A shares, sales charges.
 
TRANSFER OF ACCOUNTS.  If a shareholder holding shares of a Fund in a
PaineWebber brokerage account transfers his or her brokerage account to another
firm, the Fund shares normally will be transferred to an account with the
Transfer Agent. However, if the other firm has entered into a selected dealer
agreement with Mitchell Hutchins relating to a Fund, the shareholder may be able
to hold Fund Shares in an account with the other firm.
 
- --------------------------------------------------------------------------------
                              DIVIDENDS AND TAXES
- --------------------------------------------------------------------------------
 
DIVIDENDS.  Dividends from each Fund's net investment income are declared daily
and paid monthly. California Tax-Free Income Fund pays dividends about the fifth
day of each month and National Tax-Free Income Fund pays dividends about the
fifteenth day of each month. Municipal High Income Fund and New York Tax-Free
Income Fund pay dividends on or about the first Wednesday of each month. Net
investment income includes accrued interest and discount, less amortization of
premium and accrued expenses, with respect to municipal securities. Each Fund
distributes substantially all of its net capital gain (the excess of net

long-term capital gain over net short-term capital loss), if any, together with
any other taxable income (including any net short-term capital gain) at least
annually. A Fund may make more frequent distributions of any net capital gain
and other taxable income if necessary to avoid a 4% excise tax on undistributed
income and capital gain.
 
Dividends and other distributions on all Classes of shares of a Fund are
calculated at the same time
 
                              --------------------
                               Prospectus Page 28

                  PAINEWEBBER CALIFORNIA TAX-FREE INCOME FUND
                     PAINEWEBBER MUNICIPAL HIGH INCOME FUND
                   PAINEWEBBER NATIONAL TAX-FREE INCOME FUND
                   PAINEWEBBER NEW YORK TAX-FREE INCOME FUND
 
and in the same manner. Dividends on Class B and Class C shares of a Fund are
expected to be lower than those on its Class A shares because of the higher
expenses resulting from distribution fees borne by the Class B and Class C
shares. For the same reason, dividends on Class B shares are expected to be
lower than those for Class C shares. Dividends on each Class also might be
affected differently by the allocation of other Class-specific expenses. See
'Valuation of Shares.'
 
Shares purchased through PaineWebber investment executives and correspondent
firms begin earning dividends on the Business Day following the date payment for
such shares is due; shares purchased through the Transfer Agent begin earning
dividends on the Business Day following the Transfer Agent's receipt of payment
for such shares. Shares acquired through an exchange begin earning dividends on
the Business Day following the day on which the exchange is effected.
 
Each Fund's dividends and other distributions are paid in additional Fund shares
of the same Class at net asset value unless the shareholder has requested cash
payments. Shareholders who wish to receive dividends and/or capital gain
distributions in cash, either mailed to the shareholder by check or credited to
the shareholder's PaineWebber account, should contact their PaineWebber
investment executives or correspondent firms or complete the appropriate section
of the application form.
 
FEDERAL INCOME TAX.  Each Fund intends to continue to qualify for treatment as a
regulated investment company ('RIC') under the Internal Revenue Code so that it
will be relieved of federal income tax on the part of its investment company
taxable income (consisting generally of taxable net investment income and net
short-term capital gain) and net capital gain that is distributed to its
shareholders.
 
Distributions by a Fund that it designates as 'exempt-interest dividends'
generally may be excluded from gross income by a shareholder. In order to pay
exempt-interest dividends to its shareholders, a Fund must (and intends to
continue to) satisfy the requirement that, at the close of each quarter of its
taxable year, at least 50% of the value of its total assets consists of

municipal securities.
 
Interest on indebtedness incurred or continued by a shareholder to purchase or
carry Fund shares is not deductible. If a Fund invests in certain PABs,
shareholders must include a portion of their exempt-interest dividends from that
Fund in calculating their liability for the AMT. Corporate shareholders must
include all of their exempt-interest dividends in calculating their liability
for that tax.
 
If a Fund realizes capital gains as a result of market transactions, any
distribution of those gains is taxable to its shareholders.
 
Each Fund notifies its shareholders following the end of each calendar year of
the amounts of exempt-interest dividends (and any portion thereof that is not
AMT exempt interest), taxable dividends and capital gain distributions paid (or
deemed paid) that year.
 
A redemption of shares of a Fund may result in taxable gain or loss to the
redeeming shareholder, depending upon whether the redemption proceeds are more
or less than the shareholder's adjusted basis for the redeemed shares (which
normally includes any initial sales charge paid on Class A shares). An exchange
of Fund shares for shares of another PaineWebber mutual fund generally will have
similar tax consequences.
 
No gain or loss will be recognized to a shareholder as a result of a conversion
of Class B shares into Class A shares.
 
CALIFORNIA TAXES.  If California Tax-Free Income Fund continues to qualify as a
RIC under the Internal Revenue Code and at the end of each quarter of such
Fund's taxable year at least 50% of the value of its total assets consists of
California Obligations, exempt-interest dividends paid by the California
Tax-Free Income Fund that are derived from interest on qualifying California
Obligations will be exempt from California personal income tax ('California
exempt-interest dividends'), but not California franchise tax. Dividends and
other distributions derived from interest on other municipal securities, taxable
income and capital gains are taxable under California law at ordinary income
rates. Interest on indebtedness incurred by a shareholder to purchase or carry
shares of the Fund is not deductible for California personal income tax
purposes. California exempt-interest dividends may affect the calculation of
certain adjustments to alternative minimum taxable income for shareholders that
are corporations. The Fund itself will not be subject to California franchise or
corporate income tax on interest income or net capital gain distributed to its
shareholders.

                   PAINEWEBBER NEW YORK TAX-FREE INCOME FUND
 

NEW YORK STATE AND NEW YORK CITY TAXES.  If New York Tax-Free Income Fund
continues to qualify as a RIC under the Internal Revenue Code and at the end of
each quarter of such Fund's taxable year at least 50% of the value of its total
assets consists of New York Obligations, exempt-interest dividends paid by New
York Tax-Free Income Fund that are derived from interest on qualifying New York
Obligations will be exempt from New York State and New York City personal income
taxes, but not corporate franchise taxes. Dividends and other distributions
derived from taxable income and capital gains are not exempt from New York State
and New York City taxes. Interest on indebtedness incurred or continued by a
shareholder to purchase or carry shares of the Fund is not deductible for New
York State or New York City personal income tax purposes. Shareholders receive
notification annually stating the portion of the Fund's tax-exempt income
attributable to issuers in New York State, New York City and other states.
Interest income of New York Tax-Free Income Fund which is distributed to
shareholders will generally not be taxable to the Fund for purposes of the New
York State corporation franchise tax or the New York City general corporation
tax.
 
ADDITIONAL INFORMATION.  The foregoing is only a summary of some of the
important federal income tax and California, New York State and New York City
personal income tax considerations generally affecting each Fund and its
shareholders; see the Statement of Additional Information for a further
discussion. There may be other federal, state or local tax considerations
applicable to a particular investor. Therefore prospective investors are urged
to consult their tax advisers.
 
- --------------------------------------------------------------------------------
                              VALUATION OF SHARES
- --------------------------------------------------------------------------------
 
The net asset value of each Fund's shares fluctuates and is determined
separately for each Class as of the close of regular trading on the NYSE
(currently 4:00 p.m., Eastern time) each Business Day. Each Fund's net asset
value per share is determined by dividing the value of the securities held by
the Fund plus any cash or other assets minus all liabilities by the total number
of Fund shares outstanding.
 
Each Fund values its assets based on their current market value when market
quotations are readily available or, when such market quotations are not
available, based upon appraisals received from a pricing system using a
computerized matrix system or based upon appraisals derived from information
from recognized dealers. If such value cannot be established, assets are valued
at fair value as determined in good faith by or under the direction of that
Fund's board of trustees. The amortized cost method of valuation generally is
used to value debt obligations with 60 days or less remaining to maturity,
unless the board of trustees determines that this does not represent fair value.
It should be recognized that judgment plays a greater role in valuing lower
rated debt securities in which Municipal High Income Fund may invest, because
there is less reliable, objective data available.
 
- --------------------------------------------------------------------------------
                                   MANAGEMENT
- --------------------------------------------------------------------------------
 

The board of trustees for each Trust, as part of its overall management
responsibility, oversees various organizations responsible for the day-to-day
management of each Fund in that Trust. Mitchell Hutchins, investment adviser and
administrator of each Fund, makes and implements all investment decisions and
supervises all aspects of each Fund's operations. Mitchell Hutchins receives a
monthly fee from each of California Tax-Free Income Fund and National Tax-Free
Income Fund for these services at the annual rate of 0.50% of that Fund's
average daily net assets and from each of Municipal High Income Fund and New
York Tax-Free Income Fund at the annual rate of 0.60% of that Fund's average

daily net assets. Brokerage transactions for each Fund may be conducted through
PaineWebber in accordance with procedures adopted by the Trust's board of
trustees.
 
Each Fund also pays PaineWebber an annual fee of $4.00 per active shareholder
account held at PaineWebber for certain services not provided by the Transfer
Agent. Each Fund incurs other expenses and, for the fiscal year ended February
28, 1995, the Funds' total expenses for their Class A shares, Class B shares and
Class C shares, respectively, stated as a percentage of net assets were as
follows: 0.88%, 1.64% and 1.40% for California Tax-Free Income Fund, 0.88%,
1.64% and 1.40% for National Tax-Free Income Fund, 1.13%, 1.87% and 1.63% for
Municipal High Income Fund and 1.01%, 1.76% and 1.52% for New York Tax-Free
Income Fund. Mitchell Hutchins and PaineWebber waived a portion of their
advisory and administration, distribution and other fees and reimbursed New York
Tax-Free Income Fund for a portion of its expenses. If such waivers and
reimbursements had not been made, that Fund's ratio of expenses for its Class A,
Class B and Class C shares stated as a percentage of average net assets would
have been 1.26%, 2.01% and 1.75%, respectively.
 
Mitchell Hutchins is located at 1285 Avenue of the Americas, New York, New York
10019. It is a wholly owned subsidiary of PaineWebber, which is in turn wholly
owned by Paine Webber Group Inc., a publicly owned financial services holding
company. As of October 31, 1995, Mitchell Hutchins was adviser or subadviser of
38 investment companies with 75 separate portfolios and aggregate assets of over
$29.0 billion.
 
Gregory W. Serbe, a vice president of each Trust and a managing director of
Mitchell Hutchins, is the portfolio manager and has day-to-day responsibility
for New York Tax-Free Income Fund. Mr. Serbe is also a portfolio manager for the
other three Funds. In the case of California Tax-Free Income Fund, Cynthia N.
Bow, a vice president of Mitchell Hutchins, is a portfolio manager and has
day-to-day responsibility for the Fund. In the case of National Tax-Free Income
Fund, Richard S. Murphy, a senior vice president of Mitchell Hutchins, is a
portfolio manager and has day-to-day responsibility for the Fund. In the case of

Municipal High Income Fund, William W. Veronda, a senior vice president of
Mitchell Hutchins, is a portfolio manager and has day-to-day responsibility for
the Fund. Mr. Serbe has held his Fund responsibilities since the Funds'
inception. Ms. Bow, Mr. Murphy and Mr. Veronda, have held their Fund
responsibilities since April 1993, July 1994 and September 1995, respectively.
 
Mr. Serbe manages or oversees tax-exempt fixed income funds having aggregate
assets of more than $3.6 billion. Mr. Serbe has been with Mitchell Hutchins
since 1983. Ms. Bow has been with Mitchell Hutchins since 1982. Mr. Murphy has
been with Mitchell Hutchins since April 1994. From 1990 to March 1994, he was a
vice president at American International Group, where he managed the municipal
bond portfolio. Mr. Veronda has been with Mitchell Hutchins since September
1995. From 1984 to August 1995, he was a senior vice president and general
manager at Invesco Funds Group, where he managed municipal bond and high yield
corporate bond portfolios.
 
Other members of Mitchell Hutchins' tax-exempt investments group provide input
on market outlook, interest rate forecasts, and other considerations pertaining
to tax-exempt investments.
 
Mitchell Hutchins investment personnel may engage in securities transactions for
their own accounts pursuant to a code of ethics that establishes procedures for
personal investing and restricts certain transactions.
 
DISTRIBUTION ARRANGEMENTS. Mitchell Hutchins is the distributor of each Fund's
shares and has appointed PaineWebber as the exclusive dealer for the sale of
those shares. Under separate plans of distribution pertaining to each Fund's
Class A shares, Class B shares and Class C shares ('Class A Plan', 'Class B
Plan' and 'Class C Plan,' collectively, 'Plans'), each Fund pays Mitchell
Hutchins monthly service fees at the annual rate of 0.25% of the average daily
net assets of each Class of shares. Each Fund also pays Mitchell Hutchins
monthly distribution fees at the annual rate of 0.75% of the average daily net
assets of the Class B shares and 0.50% of the average daily net assets of the
Class C shares.
 
Under all three Plans, Mitchell Hutchins uses the service fees primarily to pay
PaineWebber for shareholder servicing, currently at the annual rate of 0.25% of
the aggregate investment amounts maintained in each Fund by PaineWebber clients.
PaineWebber passes on a portion of these fees to its investment executives to
compensate them for

shareholder servicing that they perform, and it retains the remainder to offset
its own expenses in servicing and maintaining shareholder accounts. These
expenses may include costs of the PaineWebber branch office in which the

investment executive is based, such as rent, communications equipment, employee
salaries and other overhead costs.
 
Mitchell Hutchins uses the distribution fees under the Class B and Class C Plans
to offset the commissions it pays to PaineWebber for selling the Fund's Class B
and Class C shares. PaineWebber passes on to its investment executives a portion
of these commissions and retains the remainder to offset its expenses in selling
Class B and Class C shares. These expenses may include the branch office costs
noted above. In addition, Mitchell Hutchins uses the distribution fees under the
Class B and Class C Plans to offset each Fund's marketing costs attributable to
such Classes, such as preparation of sales literature, advertising and printing
and distributing prospectuses and other shareholder materials to prospective
investors. Mitchell Hutchins also may use the distribution fees to pay
additional compensation to PaineWebber and other costs allocated to Mitchell
Hutchins' and PaineWebber's distribution activities, including employee
salaries, bonuses and other overhead expenses.
 
Mitchell Hutchins expects that, from time to time, PaineWebber will pay
shareholder servicing fees and sales commissions to its investment executives at
the time of sale of Class C shares of the Funds, and that PaineWebber may make
such payments from time to time in the future with respect to Class C shares of
one or more of the Funds. If PaineWebber makes such payments, it will retain the
service and distribution fees on Class C shares until it has been reimbursed and
thereafter will pass a portion of the service and distribution fees on Class C
shares on to its investment executives.
 
Mitchell Hutchins receives the proceeds of the initial sales charge paid upon
the purchase of Class A shares and the contingent deferred sales charge paid
upon certain redemptions of shares, and may use these proceeds for any of the
distribution expenses described above. See 'Purchases.'
 
During the period they are in effect, the Plans and related distribution
contracts pertaining to each Class of shares ('Distribution Contracts') obligate
the Funds to pay service and distribution fees to Mitchell Hutchins as
compensation for its service and distribution activities, not as reimbursement
for specific expenses incurred. Thus, even if Mitchell Hutchins' expenses exceed
its service or distribution fees for a Fund, the Fund will not be obligated to
pay more than those fees and, if Mitchell Hutchins' expenses are less than such
fees, it will retain its full fees and realize a profit. Each Fund will pay the
service and distribution fees to Mitchell Hutchins until either the applicable
Plan or Distribution Contract for that Fund is terminated or not renewed. In
that event, Mitchell Hutchins' expenses in excess of service and distribution
fees received or accrued through the termination date will be Mitchell Hutchins'
sole responsibility and not obligations of the Fund. In their annual
consideration of the continuation of each Fund's Plans, the trustees will review
the Plan and Mitchell Hutchins' corresponding expenses for each Class separately
from the Plan and corresponding expenses for the other two Classes.

                            PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
Each Fund performs a standarized computation of annualized total return and may
show this return in advertisements or promotional materials. Standardized return

shows the change in value of an investment in the Fund as a steady compound
annual rate of return. Actual year-by-year returns fluctuate and may be higher
or lower than standardized return. Standardized return for the Class A shares
reflects deduction of the Fund's maximum initial sales charge at the time of
purchase, and standardized return for the Class B shares and Class C shares
reflects deduction of the applicable contingent deferred sales charge imposed on
a redemption of shares held for the period. One-, five- and ten-year periods
will be shown, unless the Class has been in existence for a shorter period.
 
                              --------------------

                   PAINEWEBBER NEW YORK TAX-FREE INCOME FUND
 
Total return calculations assume reinvestment of dividends and other
distributions.
 
Each Fund may use other total return presentations in conjunction with
standardized return. These may cover the same or different periods as those used
for standardized return and may include cumulative returns, average annual
rates, actual year-by-year rates or any combination thereof. Non-standardized
return does not reflect initial or contingent deferred sales charges and would
be lower if such charges were included.
 
Each Fund also may advertise its yield or tax-equivalent yield. Yield reflects
investment income net of expenses over a 30-day (or one-month) period on a Fund
share, expressed as an annualized percentage of the maximum offering price per
share for Class A shares and net asset value per share for Class B shares and
Class C shares at the end of the period. Tax-equivalent yield shows the yield
that would produce the same income after a stated rate of taxes as the Fund's
tax-exempt yield (yield excluding taxable income). Yield computations differ
from other accounting methods and therefore may differ from dividends actually
paid or reported net income.
 
Total return and yield information reflects past performance and does not
necessarily indicate future results. Investment return and principal values will
fluctuate, and proceeds upon redemption may be more or less than a shareholder's
cost.

                              GENERAL INFORMATION
- --------------------------------------------------------------------------------
 
ORGANIZATION.  Both PaineWebber Municipal Series and PaineWebber Mutual Fund
Trust are Massachusetts business trusts which are registered with the SEC as
open-end management investment companies. PaineWebber Municipal Series was
organized under a Declaration of Trust dated January 28, 1987 and PaineWebber
Mutual Fund Trust was organized under a Declaration of Trust dated November 21,
1986. The trustees of each Trust have authority to issue an unlimited number of

shares of beneficial interest of separate series, par value $.001 per share.
Although each Trust is offering only the shares of its Funds, it is possible
that a Trust could become liable for misstatement in this Prospectus about a
Fund of the other Trust. The trustees of each Trust have considered this factor
in approving the use of a combined Prospectus.
 
The shares of beneficial interest of each Fund are divided into four Classes,
designated Class A shares, Class B shares, Class C shares and Class Y shares.
Each Class represents interests in the same assets of each Fund. Classes A, B
and C differ as follows: (1) each Class has exclusive voting rights on matters
pertaining to its plan of distribution, (2) Class A shares are subject to an
initial sales charge, (3) Class B shares bear ongoing distribution fees, are
subject to a contingent deferred sales charge upon most redemptions and will
automatically convert to Class A shares approximately six years after issuance,
(4) Class C shares are not subject to an initial sales charge, but are subject
to a contingent deferred sales charge if redeemed within one year of purchase,
bear ongoing distribution fees and do not convert into another Class and (5)
each Class may bear differing amounts of certain Class-specific expenses. Class
Y shares, which may be offered only to limited classes of investors, are subject
to neither an initial or contingent deferred sales charge nor ongoing service or
distribution fees. Neither Trust's board of trustees anticipates that there will
be any conflicts among the interests of the holders of each Class of Fund
shares. On an ongoing basis, each board of trustees will consider whether any
such conflict exists and, if so, take appropriate action.
 
The different sales charges and other expenses applicable to the different
Classes of Fund shares may affect the performance of those classes. More
information concerning Class Y shares of National Tax-Free Income Fund may be
obtained from a PaineWebber investment executive or correspondent firm or by
calling 1-800-647-1568. The other Funds do not currently offer Class Y shares.
 
The Trusts do not hold annual shareholder meetings. There normally will be no
meetings of shareholders to elect trustees unless fewer than a majority of the
trustees holding office have been elected by shareholders. Shareholders of
record holding at least two-thirds of the outstanding shares

of a Trust may remove a trustee by votes cast in person or by proxy at a meeting
called for that purpose. The trustees of a Trust are required to call a meeting
of shareholders for the purpose of voting upon the question of removal of any
trustee when so re-quested in writing by the shareholders of record holding at
least 10% of the Trust's outstanding shares. Each share of each Fund has equal
voting rights, except as noted above. Each share of each Fund is entitled to
participate equally in dividends and other distributions and the proceeds of any
liquidation, except that, due to the differing expenses borne by the four

Classes of shares, such dividends are likely to be lower on the Class B and
Class C shares than on the Class A shares and are likely to be lower on the
Class B shares than on the Class C shares. The shares of each series of a Trust
will be voted separately except when an aggregate vote of all series is required
by the 1940 Act.
 
To avoid additional operating costs and for investor convenience, the Funds do
not issue share certificates. Ownership of shares of each Fund is recorded on a
share register by the Transfer Agent and shareholders have the same rights of
ownership with respect to such shares as if certificates had been issued.
 
CUSTODIAN AND TRANSFER AGENT.  State Street Bank and Trust Company, One Heritage
Drive, North Quincy, Massachusetts 02171 is custodian of each Fund's assets.
PFPC Inc., a subsidiary of PNC Bank, National Association, whose principal
business address is 400 Bellevue Parkway, Wilmington, Delaware 19809, is the
Funds' transfer and dividend disbursing agent.
 
CONFIRMATIONS AND STATEMENTS.  Shareholders receive confirmations of purchases
and redemptions of shares of the Funds. PaineWebber clients receive statements
at least quarterly that report their Fund activity and consolidated year-end
statements that show all Fund transactions for that year. Shareholders who are
not PaineWebber clients receive quarterly statements from the Transfer Agent.
Shareholders also receive audited annual and unaudited semi-annual financial
statements of the Funds.

                                  APPENDIX A
 
- --------------------------------------------------------------------------------
 
     Each Fund may invest in a variety of municipal securities, as described
below:
 
     MUNICIPAL BONDS.  Municipal bonds are debt obligations issued to obtain
funds for various public purposes 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. The term 'municipal bonds' also includes 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. The Funds do not presently
intend to purchase municipal lease obligations that are not rated by Moody's or
S&P.
 
     INDUSTRIAL DEVELOPMENT BONDS AND PRIVATE ACTIVITY BONDS.  IDBs and PABs 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 included within the term '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
'Dividends and Taxes.' Each Fund is authorized to invest more than 25% of its
net assets in IDBs and PABs.
 
     FLOATING RATE AND VARIABLE RATE OBLIGATIONS.  Floating rate and variable

rate obligations bear interest at rates that are not fixed, but that vary with
changes in specified market rates or indices. Accordingly, as interest rates
decrease or increase, the potential for capital appreciation or capital
depreciation is less than for fixed rate obligations. Floating rate or variable
rate obligations typically permit the holder to demand payment of principal from
the issuer or remarketing agent at par value prior to maturity and may permit
the issuer to prepay principal, plus accrued interest, at its discretion after a
specified notice period. Frequently, floating rate or variable rate obligations
and/or the demand features thereon are secured by letters of credit or other
credit support arrangements provided by banks, the credit standing of which
affects the credit quality of the obligations.
 
     PARTICIPATION INTERESTS.  Participation interests are interests in
municipal bonds, including IDBs and 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.
 
     TENDER OPTION BONDS.  Tender option bonds are long-term municipal
securities sold by a bank subject to a 'tender option' that gives the purchaser
the right to tender them to the bank at par plus accrued interest at designated
times (the 'tender option'). The tender option may be exercisable at intervals
ranging from bi-weekly to semi-annually, 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

                   PAINEWEBBER NEW YORK TAX-FREE INCOME FUND
 
option generally would not be exercisable in the event of a default on, or
significant downgrading of, the underlying municipal securities. Therefore, a
Fund's ability to exercise the tender option will be affected by the credit
standing of both the bank involved and the issuer of the underlying securities.
 
     PUT BONDS.  A put bond is a municipal bond which 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.
 
     TAX-EXEMPT COMMERCIAL PAPER AND SHORT-TERM MUNICIPAL NOTES.  Tax-exempt
commercial paper and short-term municipal notes include 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.
 
     INVERSE FLOATERS.  Each Fund may invest in municipal obligations on which
the rate of interest varies inversely with interest rates on other municipal
obligations or an index. Such obligations include components of securities on
which interest is paid in two separate parts-an auction component, which pays
interest at a market rate that is set periodically through an auction process or
other method, and a residual component, or 'inverse floater,' which pays
interest at a rate equal to the difference between the rate that the issuer
would have paid on a fixed-rate obligation at the time of issuance and the rate
paid on the auction component. The market value of an inverse floater will be
more volatile than that of a fixed-rate obligation and, like most debt
obligations, will vary inversely with changes in interest rates.
 
     Because the interest rate paid to holders of inverse floaters is generally
determined by subtracting the interest rate paid to the holders of auction
components from a fixed amount, the interest rate paid to holders of inverse
floaters will decrease as market rates increase and increase as market rates
decrease. Moreover, the extent of the increases and decreases in the market
value of inverse floaters may be larger than comparable changes in the market
value of an equal principal amount of a fixed rate municipal obligation having
similar credit quality redemption provisions and maturity. In a declining
interest rate environment, inverse floaters can provide a Fund with a means of
increasing or maintaining the level of tax-exempt interest paid to shareholders.
However, because of the market volatility associated with inverse floaters, no
Fund will invest more than 10% of its total assets in inverse floaters.

                                  APPENDIX B
 
- --------------------------------------------------------------------------------
 
     Municipal bonds are rated by Moody's and S&P. Moody's and S&P also publish
separate ratings for municipal notes and tax-exempt commercial paper.
Descriptions of these ratings are set forth below.
 
DESCRIPTION OF MOODY'S MUNICIPAL BOND RATINGS:
 
     Aaa.  Bonds which are rated Aaa are judged to be of the best quality and
carry the smallest degree of investment risk. Interest payments are protected by
a large or by an exceptionally stable margin and principal is secure. While the
various protective elements are likely to change, such changes as can be
visualized are most unlikely to impair the fundamentally strong position of such
issues.
 
     Aa.  Bonds which are rated Aa are judged to be of high quality by all
standards. They are rated lower than the Aaa bonds because margins of protection
may not be as large as in Aaa securities, fluctuation of protective elements may
be of greater amplitude, or there may be other elements present which made the
long-term risks appear somewhat larger than in Aaa securities.
 
     A.  Bonds which are rated A are judged to be upper medium grade
obligations. Security for principal and interest are considered adequate, but
elements may be present which suggest susceptibility to impairment sometime in
the future.
 
     Baa.  Bonds which are rated Baa are considered as medium grade obligations,
i.e., they are neither highly protected nor poorly secured. Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.
 
     Ba.  Bonds which are rated Ba are judged to have speculative elements;
their future cannot be considered as well assured. Often the protection of
interest and principal payments may be very moderate and thereby not well
safeguarded during both good and bad times over the future. Uncertainty of
position characterizes bonds in this class.
 
     B.  Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
     Caa.  Bonds which are rated Caa are of poor standing. Such issues may be in

default or there may be present elements of danger with respect to principal or
interest.
 
     Ca.  Bonds which are rated Ca represent obligations which are speculative
in a high degree. Such issues are often in default or have other marked
shortcomings.
 
     C.  Bonds which are rated C are the lowest rated class of bonds and issues
so rated can be regarded as having extremely poor prospects of ever attaining
any real investment standing.
 
DESCRIPTION OF S&P'S MUNICIPAL BOND RATINGS:
 
     AAA.  Debt rated AAA has the highest rating assigned by S&P. Capacity to
pay interest and repay principal is extremely strong.
 
     AA.  Debt rated AA has a very strong capacity to pay interest and repay
principal and differs from the highest rated issues only in small degree.
 
                              --------------------

                  PAINEWEBBER CALIFORNIA TAX-FREE INCOME FUND
                     PAINEWEBBER MUNICIPAL HIGH INCOME FUND
                   PAINEWEBBER NATIONAL TAX-FREE INCOME FUND
                   PAINEWEBBER NEW YORK TAX-FREE INCOME FUND
 
     A.  Debt rated A has a strong capacity to pay interest and repay principal
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher rated categories.
 
     BBB.  Debt rated BBB is regarded as having adequate capacity to pay
principal and interest. Whereas it normally exhibits protection parameters,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity to pay interest and repay principal for debt in this
category than in higher rated categories.
 
     BB, B, CCC, CC AND C.  Debt rated BB, B, CCC, CC and C is regarded as
having predominantly speculative characteristics with respect to capacity to pay
interest and repay principal. BB indicates the least degree of speculation and C
the highest. While such debt will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major risk
exposures to adverse conditions.
 
     CI.  This rating is reserved for income bonds on which no interest is being
paid.
 
     D.  Debt rated D is in payment default. The D rating category is used when
interest payments or principal payments are not made on the date due even if the
applicable grace period has not expired, unless S&P believes that such payments
will be made during such grace period. The D rating also will be used upon the
filing of a bankruptcy petition if debt service payments are continued.

 
     Plus (+) or minus (-): The ratings from AA to CCC may be modified by the
addition of a plus or minus sign to show relative standing within the major
ratings categories.
 
DESCRIPTION OF MOODY'S RATINGS OF STATE AND MUNICIPAL NOTES AND OTHER SHORT-TERM
LOANS:
 
     Moody's ratings for state and municipal notes and other short-term loans
are designated 'Moody's Investment Grade' ('MIG' or, for variable or floating
rate obligations, 'VMIG'). Such ratings recognize the differences between
short-term credit risk and long-term risk. Factors affecting the liquidity of
the borrower and short-term cyclical elements are critical in short-term
ratings. Symbols used will be as follows:
 
          MIG-1/VMIG-1.  This designation denotes best quality. There is present
     strong protection by established cash flows, superior liquidity support or
     demonstrated broad-based access to the market for refinancing.
 
          MIG-2/VMIG-2.  This designation denotes high quality. Margins of
     protection are ample although not so large as in the preceding group.
 
          MIG-3/VMIG-3.  This designation denotes favorable quality. All
     security elements are accounted for but there is lacking the undeniable
     strength of the preceding grades. Liquidity and cash flow protection may be
     narrow and market access for refinancing is likely to be less well
     established.
 
          MIG-4/VMIG-4.  This designation denotes adequate quality. Protection
     commonly regarded as required of an investment security is present and
     although not distinctly or predominantly speculative, there is specific
     risk.
 
DESCRIPTION OF S&P'S RATINGS OF STATE AND MUNICIPAL NOTES AND OTHER SHORT-TERM
LOANS:
 
     S&P's tax-exempt note ratings are generally given to such notes that mature
in three years or less. The three rating categories are as follows:
 
          SP-1.  Strong capacity to pay principal and interest. Issues
     determined to possess very strong characteristics are given a plus (+)
     designation.
 
          SP-2.  Satisfactory capacity to pay principal and interest with some
     vulnerability to adverse financial and economic changes over the term of
     the notes.
 
          SP-3.  Speculative capacity to pay principal and interest.

                   PAINEWEBBER NEW YORK TAX-FREE INCOME FUND
 
DESCRIPTION OF COMMERCIAL PAPER RATINGS
 
     Commercial paper rated Prime-1 by Moody's are judged by Moody's to be of
the best quality. Their short-term debt obligations carry the smallest degree of
investment risk. Margins of support for current indebtedness are large or stable
with cash flow and asset protection well assured. Current liquidity provides
ample coverage of near-term liabilities and unused alternative financing
arrangements are generally available. While protective elements may change over
the intermediate or longer term, such changes are most unlikely to impair the
fundamentally strong position of short-term obligations.
 
     Commercial paper rated A by S&P have the following characteristics.
Liquidity ratios are better than industry average. Long-term debt rating is A or
better. The issuer has access to at least two additional channels of borrowing.
Basic earnings and cash flow are in an upward trend. Typically, the issuer is a
strong company in a well-established industry and has superior management.
Issuers rated A are further refined by use of numbers 1, 2, and 3 to denote
relative strength within this highest classification. Those issues rated A-1
that are determined by S&P to possess extremely strong safety characteristics

                      STATEMENT OF ADDITIONAL INFORMATION
 
     The four funds named above (each a 'Fund') are series of either PaineWebber
Mutual Fund Trust or PaineWebber Municipal Series (each a 'Trust'),
professionally managed mutual funds. PaineWebber California Tax-Free Income Fund
('California Tax-Free Income Fund') seeks 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.
PaineWebber National Tax-Free Income Fund ('National Tax-Free Income Fund')
seeks high current income exempt from federal income tax, consistent with the
preservation of capital and liquidity within the Fund's quality standards.
PaineWebber Municipal High Income Fund ('Municipal High Income Fund') seeks high
current income exempt from federal income tax. PaineWebber New York Tax-Free
Income Fund ('New York Tax-Free Income Fund') seeks high current income exempt
from federal income tax and from New York State and New York City personal
income taxes. The Funds' investment adviser, administrator and distributor is
Mitchell Hutchins Asset Management Inc. ('Mitchell Hutchins'), a wholly owned
subsidiary of PaineWebber Incorporated ('PaineWebber'). As distributor for the
Funds, Mitchell Hutchins has appointed PaineWebber to serve as the exclusive
dealer for the sale of Fund shares. This Statement of Additional Information is
not a prospectus and should be read only in conjunction with the Funds' current
Prospectus, dated November 10, 1995. A copy of the Prospectus may be obtained by
calling any PaineWebber investment executive or correspondent firm or by calling
toll-free 1-800-647-1568. This Statement of Additional Information is dated
November 10, 1995, as revised January 22, 1996.
 
                      INVESTMENT POLICIES AND RESTRICTIONS
 
     The following supplements the information contained in the Prospectus
concerning the Funds' investment policies and limitations.
 
     RATINGS AS INVESTMENT CRITERIA.  Moody's Investors Service, Inc.
('Moody's') and Standard & Poor's, a division of The McGraw Hill Companies, Inc.
('S&P') are private services that provide ratings of the credit quality of debt
obligations, including issues of municipal securities. A description of the
range of ratings assigned to municipal securities by Moody's and S&P is included
in Appendix B to the Prospectus. The Funds may use these ratings in determining
whether to purchase, sell or hold a security. It should be emphasized, however,
that ratings are general and are not absolute standards of quality.
Consequently, municipal securities with the same maturity, interest rate and
rating may have different market prices. Credit ratings attempt to evaluate the
safety of principal and interest payments and do not evaluate the risks of
fluctuations in market value. Also, rating agencies may fail to make timely
changes in credit ratings in response to subsequent events, so that an issuer's
current financial condition may be better or worse than the rating indicates.
Subsequent to its purchase by a Fund, an issue of municipal securities may cease

to be rated or its rating may be reduced below the minimum rating required for
purchase by the Fund.

<PAGE>
     Opinions relating to the validity of municipal securities and to the
exemption of interest thereon from federal income tax (and also, when available,
from the federal alternative minimum tax) and (where applicable) California
personal income tax and New York State and New York City personal income taxes
are rendered by bond counsel to the respective issuing authorities at the time
of issuance. Neither the Funds nor Mitchell Hutchins will review the proceedings
relating to the issuance of municipal securities or the basis for such opinions.
An issuer's obligations under its municipal securities are subject to the
provisions of bankruptcy, insolvency and other laws affecting the rights and
remedies of creditors (such as the federal bankruptcy laws) and federal, state
and local laws that may be enacted that adversely affect the tax-exempt status
of interest on the municipal securities held by a Fund or of the exempt-interest
dividends received by a Fund's shareholders, extend the time for payment of
principal or interest, or both, or impose other constraints upon enforcement of
such obligations. There is also the possibility that, as a result of litigation
or other conditions, the power or ability of issuers to meet their obligations
for the payment of principal of and interest on their municipal securities may
be materially and adversely affected.
 
     TYPES OF MUNICIPAL SECURITIES.  The types of municipal securities
identified in the Prospectus may include obligations of issuers whose revenues
are primarily derived from mortgage loans on housing projects for moderate to
low income families. The Funds also may purchase mortgage subsidy bonds 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 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).
 
     WHEN-ISSUED AND DELAYED DELIVERY SECURITIES.  As stated in the Prospectus,
the Fund may purchase securities on a 'when-issued' or delayed delivery basis. A
security purchased on a when-issued or delayed delivery basis is recorded as an
asset on the commitment date and is subject to changes in market value,
generally based upon changes in the level of interest rates. Thus, fluctuation
in the value of the security from the time of the commitment date will affect
the Fund's net asset value. When 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 'Investment Policies and
Restrictions--Segregated Accounts.' The Funds purchase when-issued securities
only with the intention of taking delivery, but may sell the right to acquire
the security prior to delivery if Mitchell Hutchins deems it advantageous to do
so, which may result in capital gain or loss to a Fund.
 
     STAND-BY COMMITMENTS.  Each Fund may acquire stand-by commitments pursuant
to which a bank or other municipal bond dealer agrees to purchase securities
that are held in the Fund's portfolio or that are being purchased by the Fund,
at a price equal to (1) the acquisition cost (excluding any accrued interest
paid on acquisition), less any amortized market premium or 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 by the Fund, whichever is later. Although the Funds do not currently
intend to acquire stand-by commitments with respect to municipal securities held
in their portfolios, each Fund may acquire such commitments under unusual market
conditions to facilitate portfolio liquidity.
 
     A Fund would 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 would be unconditional and
unqualified. A stand-by commitment would not be transferable by a Fund, although
the Fund could 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
 
                                       2
<PAGE>
subject to such a commitment (thus reducing the yield to maturity otherwise
available for the same securities). The acquisition of a stand-by commitment
would not ordinarily affect the valuation or maturity of the underlying
municipal securities. Stand-by commitments acquired by a Fund would be valued at
zero in determining net asset value. Whether the Fund paid directly or
indirectly for a stand-by commitment, its cost would be treated as unrealized
depreciation and would be amortized over the period the commitment is held by
the Fund.
 
     PUT BONDS.  Each Fund may invest in put bonds that have a fixed rate of
interest and a final maturity beyond the date on which the put may be exercised.
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.
 
     MUNICIPAL LEASE OBLIGATIONS.  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
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.
No Fund intends to invest more than 5% of its total assets in such uninsured
'non-appropriation' municipal lease obligations. There is no limitation on the
Funds' ability to invest in other municipal lease obligations.
 
     PARTICIPATION INTERESTS.  Each Fund also may invest in participation
interests in municipal bonds, including industrial development bonds ('IDBs'),
private activity bonds ('PABs') and floating and variable rate securities. 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 instrument back to the bank.
Such right generally is backed by the bank's irrevocable letter of credit or
guarantee and permits the Fund to draw on the letter of credit on demand, after
specified notice, for all or any part of the principal amount of the Fund's
participation interest plus accrued interest. Generally, each Fund intends to
exercise the demand under the letters of credit or other guarantees only (1)
upon a default under the terms of the underlying bond, (2) to maintain the
Fund's portfolio in accordance with its investment objective and policies or (3)
as needed to provide liquidity to the Fund in order to meet redemption requests.
The ability of a bank to fulfill its obligations under a letter of credit or
guarantee might be affected by possible financial difficulties of its borrowers,
adverse interest rate or economic conditions, regulatory limitations or other
factors. Mitchell Hutchins will monitor the pricing,
 
                                       3
<PAGE>
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.
 
     REPURCHASE AGREEMENTS.  The Funds do not intend to enter into repurchase
agreements except as a temporary measure and under unusual circumstances,
because repurchase agreements are transactions that generate taxable income.
Each Fund is, however, authorized to enter into repurchase agreements with U.S.
banks and dealers with respect to any obligation issued or guaranteed by the
U.S. government, its agencies or instrumentalities and also with respect to
commercial paper, bank certificates of deposit and bankers' acceptances.
Repurchase agreements are transactions in which a Fund purchases securities from
a bank or recognized securities dealer and simultaneously commits to resell the
securities to the bank or dealer at an agreed-upon date and price reflecting a
market rate of interest unrelated to the coupon rate or maturity of the
purchased securities. The Fund maintains custody of the underlying securities
prior to their repurchase; thus, the obligation of the bank or dealer to pay the
repurchase price on the date agreed to is, in effect, secured by such
securities. If the value of these securities is less than the repurchase price,
plus any agreed upon additional amount, the other party to the agreement 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
securities and the price which was paid by the Fund upon acquisition is accrued
as interest and included in the Fund's net investment income.
 

     Repurchase agreements carry certain risks not associated with direct
investments in securities, including possible declines in the market value of
the underlying securities and delays and costs to the Fund if the other party to
a repurchase agreement becomes insolvent. Each Fund intends to enter into
repurchase agreements only with banks and dealers in transactions believed by
Mitchell Hutchins to present minimal credit risks in accordance with guidelines
established by the appropriate Trust's board of trustees. Mitchell Hutchins will
review and monitor the creditworthiness of those institutions under the board's
general supervision.
 
     FLOATING RATE AND VARIABLE RATE MUNICIPAL SECURITIES.  As noted in the
Prospectus, each Fund may invest in floating rate and variable rate municipal
securities with or without demand features. A demand feature gives the Fund the
right to sell the securities to a specified party, usually a remarketing agent,
on a specified date. A demand feature is often backed by a letter of credit or
guarantee from a bank. As discussed under 'Participation Interests,' to the
extent that payment of an obligation is backed by a bank's letter of credit or
guarantee, such payment may be subject to the bank's ability to satisfy that
commitment. 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. Generally, these interest rate adjustments cause
the market value of floating rate and variable rate municipal securities to
fluctuate less than the market value of fixed rate obligations. Accordingly, as
interest rates decrease or increase, the potential for capital appreciation or
capital depreciation is less than for fixed rate obligations.
 
     ILLIQUID SECURITIES.  Each Fund may invest up to 10% of its net assets in
illiquid securities. The term 'illiquid securities' for this purpose means
securities that cannot be disposed of within seven days in the ordinary course
of business at approximately the amount at which the Fund has valued the
securities and includes, among other things, repurchase agreements maturing in
more than seven days and municipal lease obligations (including certificates of
participation) other than those Mitchell Hutchins has determined are liquid
pursuant to guidelines established by the appropriate Trust's board of trustees.
 
                                       4
<PAGE>
     Each Trust's board of trustees has delegated the function of making
day-to-day determinations of liquidity to Mitchell Hutchins, pursuant to
guidelines approved by the board. Mitchell Hutchins takes into account a number
of factors in reaching liquidity decisions, including (1) the frequency of
trades for the security, (2) the number of dealers that make quotes for the
security, (3) the number of dealers that have undertaken to make a market in the
security, (4) the number of other potential purchasers and (5) the nature of the
security and how trading is effected (e.g., the time needed to sell the
security, how offers are solicited and the mechanics of transfer). Mitchell
Hutchins monitors the liquidity of securities in each Fund's portfolio and
reports periodically on liquidity decisions to each Trust's board of trustees.
 
     In making determinations as to the liquidity of municipal lease
obligations, Mitchell Hutchins will distinguish between direct investments in
municipal lease obligations (or participations therein) and investments in
securities that may be supported by municipal lease obligations or certificates

of participation therein. Since these municipal lease obligation-backed
securities are based on a well-established means of securitization, Mitchell
Hutchins does not believe that investing in such securities presents the same
liquidity issues as direct investments in municipal lease obligations. The
assets used as cover for any over-the-counter ('OTC') options written by a Fund
would be considered illiquid unless the OTC options are sold to qualified
dealers who agree that the Fund may repurchase any OTC option it writes at a
maximum price to be calculated by a formula set forth in the option agreement.
The cover for an OTC option written subject to this procedure will be considered
illiquid only to the extent that the maximum repurchase price under the formula
exceeds the intrinsic value of the option.
 
     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, the Fund will
maintain with an approved custodian in a segregated account cash, U.S.
government securities or other liquid high-grade debt securities, marked to
market daily, in an amount at least equal to the Fund's obligation or commitment
under such transactions. As described below under 'Hedging and Related Income
Strategies,' segregated accounts may also be required in connection with certain
transactions involving options or futures contracts.
 
SPECIAL CONSIDERATIONS RELATING TO CALIFORNIA MUNICIPAL SECURITIES
 
     The financial condition of the State of California, its public authorities
and local governments could affect the market values and marketability of, and
therefore the net asset value per share and the interest income of, the Fund, or
result in the default of existing obligations, including obligations which may
be held by the Fund. The following section provides only a brief summary of the
complex factors affecting the financial condition of California, and is based on
information obtained from the State of California, as publicly available on the
date of this Statement of Additional Information. The information contained in
such publicly available documents has not been independently verified. It should
be noted that the creditworthiness of obligations issued by local issuers may be
unrelated to the creditworthiness of California, and that there is no obligation
on the part of California to make payment on such local obligations in the event
of default in the absence of a specific guarantee or pledge provided by the
State of California.
 
     The State of California has experienced significant financial difficulties
because of the 1990-93 recession, which have reduced its credit standing. The
ratings of certain related debt of other issuers for which California has an
outstanding lease purchase, guarantee or other contractual obligation (such as
for State-insured hospital bonds) are generally linked directly to California's
rating. Should the financial condition of California
 
                                       5
<PAGE>
deteriorate further, its credit ratings could be further reduced, and the market
value and marketability of all outstanding notes and bonds issued by California,
its public authorities or local governments could be adversely affected.
 
     ECONOMIC FACTORS.  California's economy is the largest among the 50 states
and one of the largest in the world. The State's population of over 32 million

represents over 12% of the total United States population. While the State's
substantial population growth during the 1980s stimulated local economic growth
and diversification, it also increased demands on State services. Total personal
income in the State, at an estimated $703 billion in 1994, accounts for more
than 12% of all personal income in the nation.
 
     From mid-1990 to late 1993, the State suffered a recession with the worst
economic, fiscal and budget conditions since the 1930s. Construction,
manufacturing (especially aerospace), and financial services, among others, were
all severely affected, particularly in Southern California. Job losses were the
worst of any post-war recession. Employment levels stabilized by late 1993 and
steady growth occurred in 1994 and 1995, but pre-recession job levels are not
expected to be reached for another year. Unemployment, while remaining higher
than the national average, has come down significantly from the January 1994
peak of 10%. Economic indicators show a steady recovery underway in California
since the start of 1994, although the residential housing sector is weaker than
in past recoveries. However, any delay or reversal of the recovery will
exacerbate shortfalls in State revenue.
 
     STATE DEBT.  Under the California Constitution, debt service on outstanding
general obligation bonds is the second charge to the General Fund after support
of the public school system and public institutions of higher education. Total
outstanding general obligation bonds and lease purchase debt of the State
increased from $9.4 billion at June 30, 1988 to $24.6 billion at June 30, 1995.
State agencies and authorities had approximately $19.0 billion of revenue bonds
and notes outstanding at June 30, 1995 for which the State General Fund has no
liability.
 
     STATE FINANCES.  Throughout the 1980's, State spending increased rapidly as
the State population and economy also grew rapidly, including increased spending
for many assistance programs to local governments, which were constrained by
Article XIIIA of the California Constitution (commonly known as 'Proposition
13') and other laws. The largest State program is assistance to local public
school districts. In 1988, an initiative (commonly known as Proposition 98) was
enacted which (subject to suspension by a two-thirds vote of the Legislature and
the Governor) guarantees local school districts and community college districts
a minimum share of State General Fund revenues (currently about 35%).
 
     Since the start of the fiscal year ('FY') 1990-91, the State has faced
adverse economic, fiscal, and budget conditions. The economic recession
seriously affected State tax revenues. It also caused increased expenditures for
health and welfare programs. The State is also facing a structural imbalance in
its budget with the largest programs supported by the General Fund (education,
health, welfare and corrections) growing at rates significantly higher than the
growth rates for the principal revenue sources of the General Fund.
 
     These structural concerns will continue in future years with the expected
need to increase capital and operating costs of the correctional system in
response to a 'Three Strikes' law enacted in 1994 which mandates life
imprisonment for certain felony offenders.
 
     Recent Budgets. As a result of these factors, among others, from the late
1980's until 1992-93, the State had a period of nearly chronic budget imbalance,
with expenditures exceeding revenues in four out of six

 
                                       6
<PAGE>
years, and the State accumulated and sustained a budget deficit in the budget
reserve, the Special Fund for Economic Uncertainties ('SFEU') approaching $2.8
billion at its peak at June 30, 1993. Starting in the 1990-91 Fiscal Year and
for each year thereafter, each budget required multibillion dollar actions to
bring projected revenues and expenditures into balance and to close large
'budget gaps' which were identified. The Legislature and Governor eventually
agreed on a number of different steps to produce Budget Acts in the years
1991-92 to 1994-95, including:
 
     o significant cuts in health and welfare program expenditures;
 
     o transfers of program responsibilities and funding from the State to local
governments, coupled with some reduction in mandates on local government;
 
     o transfer of about $3.6 billion in annual local property tax revenues from
cities, counties, redevelopment agencies and some other districts to local
school districts, thereby reducing state funding for schools;
 
     o reduction in growth of support for higher education programs, coupled
with increases in student fees;
 
     o revenue increases (particularly in the 1991-92 Fiscal Year budget), most
of which were for a short duration;
 
     o increased reliance on aid from the federal government to offset the costs
of incarcerating, educating and providing health and welfare services to
undocumented aliens (although these efforts have produced much less federal aid
than the State Administration has requested); and
 
     o various one-time adjustments and accounting changes.
 
     Despite these budget actions, the effects of the recession led to large,
unanticipated deficits in the SFEU, as compared to projected positive balances.
By the start of the 1993-94 Fiscal Year, the accumulated deficit was so large
(almost $2.8 billion) that it was impractical to budget to retire it in one
year, so a two-year program was implemented, using the issuance of revenue
anticipation warrants to carry a portion of the deficit over the end of the
fiscal year. When the economy failed to recover sufficiently in 1993-94, a
second two-year plan was implemented in 1994-95, to carry the final retirement
of the deficit into 1995-96.
 
     The combination of stringent budget actions cutting State expenditures, and
the turnaround of the economy by late 1993, finally led to the restoration of
positive financial results. While General Fund revenues and expenditures were
essentially equal in FY 1992-93 (following two years of excess expenditures over
revenues), the General Fund had positive operating results in FY 1993-94 and
1994-95, which have reduced the accumulated budget deficit to around $600
million as of June 30, 1995.
 
     A consequence of the accumulated budget deficits in the early 1990's,
together with other factors such as disbursement of funds to local school

districts 'borrowed' from future fiscal years and hence not shown in the annual
budget, was to significantly reduce the State's cash resources available to pay
its ongoing obligations. When the Legislature and the Governor failed to adopt a
budget for the 1992-93 Fiscal Year by July 1, 1992, which would have allowed the
State to carry out its normal annual cash flow borrowing to replenish its cash
reserves, the State Controller was forced to issue registered warrants ('IOUs')
to pay a variety of obligations representing prior years' or continuing
appropriations, and mandates from court orders. Available funds were used to
make constitutionally-mandated payments, such as debt service on bonds and
warrants. Between July 1 and September 4, 1992 the State Controller issued a
total of approximately $3.8 billion of registered
 
                                       7
<PAGE>
warrants. After that date, all remaining outstanding registered warrants (about
$2.9 billion) were called for redemption from proceeds of the issuance of 1992
Interim Notes after the budget was adopted.
 
     The State's cash condition became so serious in late spring of 1992 that
the State Controller was required to issue revenue anticipation warrants
maturing in the following fiscal year in order to pay the State's continuing
obligations. The State was forced to rely increasingly on external debt markets
to meet its cash needs, as a succession of notes and warrants (both forms of
short-term cash flow financing) were issued in the period from June 1992 to July
1994, often needed to pay previously-maturing notes or warrants. These
borrowings were used also in part to spread out the repayment of the accumulated
budget deficit over the end of a fiscal year.
 
     The State issued $7.0 billion of short-term debt in July 1994 to meet its
cash flow needs and to finance the deferral of part of its accumulated deficit
to the 1995-96 fiscal year. In order to assure repayment of $4.0 billion of this
borrowing which matures on April 25, 1996, the State enacted legislation (the
'Trigger Law') which can lead to automatic, across-the-board budget cuts in
General Fund expenditures if cash flow projections made at certain times
deteriorate from estimates made in July 1994 when the borrowings were made. The
State's cash position remained favorable enough during the 1994-95 fiscal year
that the State Controller determined that no automatic budget cuts were needed
in that year.
 
     Current Budget. For the first time in four years, the State entered the
1995-96 fiscal year with strengthening revenues based on an improving economy.
The major feature of the Governor's proposed Budget, a 15% phased cut in
personal income and business taxes, was rejected by the Legislature.
 
     The 1995-96 Budget Act was signed by the Governor on August 3, 1995, 34
days after the start of the fiscal year. The Budget Act projected General Fund
revenues and transfers of $44.1 billion, a 3.5 percent increase from the prior
year. Expenditures are budgeted at $43.4 billion, a 4 percent increase. The
Department of Finance projected that, after repaying the last of the carryover
budget deficit, there would be a positive balance of less than $30 million in
the budget reserve, the Special Fund for Economic Uncertainties, at June 30,
1996, providing no margin for adverse results during the year.
 
     The Department of Finance projected cash flow borrowings in the 1995-96

Fiscal Year would be the smallest in many years, comprising about $2 billion of
notes to be issued in April, 1996, and maturing by June 30, 1996. With full
payment of $4 billion of revenue anticipation warrants on April 25, 1996, the
Department saw no further need for borrowing over the end of the fiscal year.
The Department projected that available internal cash resources to pay State
obligations would be about $1.9 billion at June 30, 1996. On October 15, 1995,
the State Controller, in the last step in the Trigger Law process, reported that
projected cash resources in the General Fund during fiscal year 1995-96 would be
large enough to again avoid the need for any automatic budget cuts. However, the
Controller estimated that the State's cash position on June 30, 1996 would be
about $500 million less than estimated by the Department of Finance. General
Fund revenues during the first five months of FY 1995-96 have been reported
about 4% higher than projected when the Budget Act was adopted, reflecting
improved economic conditions.
 
     The principal features of the 1995-96 Budget Act, in addition to those
noted above, were additional cuts in health and welfare expenditures (some of
which are subject to approvals or waivers by the federal government); assumed
further federal aid for illegal immigrant costs; and an increase in per-pupil
funding for public schools and community colleges, the first such significant
increase in four years.
 
                                       8
<PAGE>
     There can be no assurance that the State will not face budget gaps in
future years, resulting from a disparity between tax revenues projected from a
lower revenue base and the spending required to maintain State programs at
current levels. To achieve a balanced budget, the enactment of legislation may
be required to enlarge the State's revenue base or to curtail current program
expenditures. Certain major budgetary considerations affecting the State are
outlined below.
 
     REVENUE BASE.  The recession seriously affected the State's tax revenue,
which basically mirrors general economic conditions. The principal sources of
General Fund revenues are economically sensitive, and include the California
personal income tax (44% of total FY1993-94 revenues), the sales tax (35%), bank
and corporation taxes (12%), and the gross premium tax on insurance (3%).
Personal income tax receipts are generated disproportionately by relatively few
taxpayers (the top 4% of taxpayers paid 49% of the total tax in 1990), and
capital gains are a significant component of such collections. Auto sales and
building materials are significant components of retail sales tax collections.
Tax rates, increased in 1991, are relatively high, and may impose political and
economic constraints on the ability of the State to further increase its taxes.
By statute, certain recent increases in the rates of income taxes will expire on
December 31, 1995. In November 1993, the voters approved a constitutional
amendment to permanently extend 0.5 percent of the sales tax for local law
enforcement and thus not available as General Fund revenues.
 
     Orange County.  On December 6, 1994, Orange County, California (the
'County'), together with its pooled investment funds (the 'Pools'), filed for
protection under Chapter 9 of the federal Bankruptcy Code, after reports that
the Pools had suffered significant market losses in their investments causing a
liquidity crisis for the Pools and the County. More than 200 other public
entities, most but not all located in the County, were also depositors in the

Pools. The County has estimated the Pools' loss at about $1.7 billion, or 23% of
its initial deposits of around $7.5 billion. Some of the entities which kept
monies in the Pools, including the County, are facing financial difficulties
because of the bankruptcy filing and may be required to reduce programs or
capital projects. The County and some of these entities have, and others may in
the future, default in payment of their obligations. Moody's and S&P have
suspended, reduced to below investment grade levels, or placed on 'Credit Watch'
various securities of the County and the entities participating in the Pools. On
May 2, 1995, the Bankruptcy Court approved a settlement agreement by which the
non-County participants in the Pools received immediate cash payments equal to
77% of their investment. Certain County obligations, which have since been
converted to cash, were issued to most participants in the amount of 3% of their
investment (except that school districts received additional distributions equal
to 13% of their investment) in return for waiving any further claims against the
County. The remaining amounts will be payable by the County from future sources
of revenue or legal claims. A few agencies (representing less than 10% of the
participations) declined to receive the additional payments above the 77% cash
payout, and have retained their rights to pursue claims against the County.
County voters on June 27, 1995 rejected a proposition to impose an additional
0.5% sales tax to help pay the County's obligations. Subsequently, holders of
about $800 million of the County's short-term notes coming due during the summer
of 1995 agreed to a one-year extension of the maturity of these notes, avoiding
an immediate default. Moody's and S&P have, however, indicated they will
consider these notes in default since they were not paid when originally due.
The County has implemented a new financial plan based in part on new revenue
sources transferred to the County from other local governments, as a result of
special legislation adopted in September 1995.
 
     The State of California has no present obligation with respect to any
obligations or securities of the County or any of the other participating
entities. However, the State may be obligated to intervene to ensure that school
districts have sufficient funds to operate, or to maintain certain
county-administered State
 
                                       9
<PAGE>
programs. As of December 1995, no school districts became insolvent as a result
of the bankruptcy of the County, and no other State obligation has been
asserted.
 
     BUDGETARY FLEXIBILITY.  Article XIIIB of the California Constitution,
adopted by voter initiative, established an 'Appropriations Limit' for the State
and local governments; excess state revenues are to be divided equally between
transfers to K-14 districts and refunds to taxpayers. A taxpayer refund has not
been required since FY1986-87.
 
     Proposition 98 established a minimum expenditure base for State aid to K-14
districts, currently requiring allocation of over 34% of General Fund revenues
to such districts.
 
     For many years starting in the early 1980s, the State maintained the SFEU
as a budget reserve in case of unexpected changes in revenues or expenditures
during a fiscal year. Since the start of the recession in 1990, the SFEU has
been in a negative balance, as the State accumulated sizable budget deficits.

The Budget Act for FY1995-96 projects elimination of the accumulated budget
deficits with a small positive balance (about $28 million) in the SFEU on June
30, 1996.
 
     LABOR COSTS.  The State government workforce is mostly unionized, subject
to the law which authorizes collective bargaining and prohibits strikes and work
slowdowns. All of the State's collective bargaining agreements expired June 30,
1995. The State has a substantial unfunded liability for future pension
benefits, and has utilized changes in its pension fund policies to reduce
current contribution requirements. If the investment assumptions used in
determining required State contributions are not sustained by actual results,
additional State contributions would be required in future years.
 
     PUBLIC ASSISTANCE.  California has the largest number of persons receiving
public assistance (Aid to Families with Dependent Children ('AFDC') and General
Relief) of any state. AFDC costs are shared among the federal government, the
State and its counties by statutory formula. Caseloads tend to rise
significantly during economic downturns, but are also significantly affected by
changing demographic and social trends which may impede the reduction of
caseloads during an economic recovery. The State has reduced AFDC payments to
meet budget pressures in recent years.
 
     MEDI-CAL.  California participates in the federal Medicaid program under a
state plan approved by the Health Care Financing Administration. The federal
government provides certain of the eligible program costs, with the remainder
shared by the State and its counties. Basic program eligibility and benefits are
determined by federal guidelines, but the State currently provides a number of
optional benefits and expanded eligibility. Program costs have increased
substantially in recent years, and account for a large share of the State
budget. The State has cut optional Medi-Cal services in recent years to reduce
expenditures. Proposed changes in the federal Medicare/Medicaid program may lead
to major restructuring of these programs in California. Federal law requires the
State to adopt reimbursement rates for hospitals and nursing homes that are
reasonable and adequate to meet the costs that must be incurred by efficiently
and economically operated facilities in providing patient care.
 
     LITIGATION.  The State is involved in certain legal proceedings (described
in the State's recent financial statements) that, if decided against the State,
may require the State to make significant future expenditures or may
substantially impair revenues.
 
     STATE ASSISTANCE TO LOCALITIES.  Property tax revenues received by local
governments declined more than 50% following voter approval of Proposition 13 in
1978. Subsequently, the California Legislature enacted measures to provide for
the redistribution of the State's General Fund surplus to local agencies, the
reallocation of certain State revenues to local agencies and the assumption of
certain governmental functions
 
                                       10
<PAGE>
by the State to assist municipal issuers to raise revenues. In response to the
State's current fiscal difficulties, the State has reduced its financial
assistance to counties and cities, and adopted measures to transfer certain
governmental functions to its counties, accompanied by new funding sources. The

FY1993-94 Budget Act eliminated the remaining Proposition 13 assistance to all
local government entities other than K-14 education districts. Such actions have
compounded the serious fiscal constraints already experienced by many local
governments, several of which have been compelled to seek special assistance
from the State.
 
     CONSTITUTIONAL, LEGISLATIVE AND OTHER FACTORS.  Certain California
constitutional amendments, legislative measures, executive orders,
administrative regulations and voter initiatives are introduced and/or
implemented from time to time which may result in adverse fiscal or economic
effects.
 
     The fiscal condition of local governments in California (58 counties, 480
cities and thousands of education, utility and other special districts) has been
constrained since the enactment of 'Proposition 13' in 1978, which reduced and
limited the future growth of property taxes, and limited the ability of local
governments to impose other taxes. Counties, in particular, have had fewer
options to raise revenues than many other local government entities, and have
been required to maintain many basic public services. A 1986 initiative statute,
called 'Proposition 62,' imposed additional limits on local governments,
essentially requiring either majority or 2/3 voter approval for any tax increase
(other than property taxes). Later court decisions had struck down most of
Proposition 62, and many local governments, particularly cities, had enacted or
raised local taxes without voter approval. In September 1995, the California
Supreme Court overruled the prior cases, and upheld the constitutionality of
Proposition 62. Many aspects of this decision remain unclear (such as its impact
on charter cities, and whether it will have retroactive effect), but its future
effect will be to further limit the fiscal flexibility of many local
governments.
 
     In the aftermath of Proposition 13, the State provided aid from the General
Fund to make up some of the loss of property tax moneys, including taking over
the principal responsibility for funding local K-12 schools and community
colleges. Under the pressure of the recent recession, the Legislature has
eliminated the remnants of this post-Proposition 13 aid, although it has also
provided additional funding sources (such as sales taxes) and reduced mandates
for local services. Nonetheless, many counties, in particular, continue to be
under severe fiscal stress. While such stress has in recent years most often
been experienced by smaller, rural counties, larger urban counties have also
been affected.
 
     Los Angeles County, the largest in the State, has reported severe fiscal
problems, leading to a nominal $1.2 billion deficit in its $12 billion budget
for the 1995-96 Fiscal Year. To balance the budget, the county has imposed
severe cuts in services, particularly for health care. Both Moody's and S&P have
reduced Los Angeles County's debt ratings in August 1995 (to 'A' and 'A-'),
respectively, and it remains on S&P Credit Watch with negative implications.
Orange County, which is presently operating under protection of the federal
Bankruptcy Court (see above), has substantially reduced services and personnel
in order to live within much reduced means.
 
SPECIAL CONSIDERATIONS RELATING TO NEW YORK MUNICIPAL SECURITIES
 
     The financial condition of the State of New York ('New York State' or the

'State'), its public authorities and public benefit corporations (the
'Authorities') and its local governments, particularly The City of New York (the
'City'), could affect the market values and marketability of, and therefore the
net asset value per share and the interest income of the Fund, or result in the
default of existing obligations, including obligations which may be held by the
Fund. The following section provides only a brief summary of the complex factors
affecting the financial situation in New York and is based on information
obtained from New York State,
 
                                       11
<PAGE>
certain of its Authorities, the City and certain other localities, as publicly
available on the date of this Statement of Additional Information. The
information contained in such publicly available documents has not been
independently verified. It should be noted that the creditworthiness of
obligations issued by local issuers may be unrelated to the creditworthiness of
New York State, and that there is no obligation on the part of New York State to
make payment on such local obligations in the event of default in the absence of
a specific guarantee or pledge provided by New York State.
 
     New York State and the City are each facing serious financial difficulties
and have each experienced recent declines in their credit standings. S&P and
Moody's have each assigned ratings for New York State's general obligation bonds
that are among the three lowest of those states with rated general obligation
bonds. The ratings of certain related debt of other issuers for which New York
State has an outstanding moral obligation, lease purchase, guarantee or other
contractual obligation are generally linked directly to the State's rating. S&P
and Moody's have each assigned ratings for the City's obligations that are among
the four lowest of those cities with rated general obligation bonds. Should the
financial condition of New York State, its Authorities or its local governments
deteriorate, their respective credit ratings could be further reduced, and the
market value and marketability of their outstanding notes and bonds could be
adversely affected, and their respective access to the public credit markets
jeopardized.
 
     ECONOMIC FACTORS.  New York is the third most populous state, and has a
relatively high level of personal wealth; however, the State economy has grown
more slowly than that of the nation as a whole, resulting in the gradual erosion
of its relative economic affluence (due to such factors such as relative costs
for taxes, labor and energy). The State's economy is diverse, with a
comparatively large share of the nation's finance, insurance, transportation,
communications and services employment, and a very small share of the nation's
farming and mining activity. New York has a declining proportion of its
workforce engaged in manufacturing and increasing proportion engaged in service
industries. The State, therefore, is likely to be less affected than the nation
as a whole during an economic recession concentrated in construction and
manufacturing sectors of the economy, but likely to be more affected during a
recession concentrated in the service-producing sector. The State's
manufacturing and maritime base have been seriously eroded, as illustrated by
the decline of the steel industry in the Buffalo area and of the apparel and
textile industries in the City. In addition, the City experienced substantial
socio-economic changes, as a large segment of its population and a significant
share of corporate headquarters and other businesses relocated (many
out-of-state).

 
     Both the State and the City experienced substantial revenue increases in
the mid-1980s attributable directly (corporate income and financial corporations
taxes) and indirectly (personal income and a variety of other taxes) to growth
in new jobs, rising profits and capital appreciation derived from the finance
sector of the City's economy. From 1977 to its 1988 peak, the finance, insurance
and real estate sectors rose 55%, to account in 1988 for 23% of total earnings
in the City and 14% statewide (compared to 7% nationwide). The finance sector's
growth was a catalyst for the New York metropolitan region's related business
and professional services, retail trade and residential and commercial real
estate markets. The then rising real estate market contributed to City revenues,
as higher property values and new construction added to collections from
property taxes, mortgage recording and transfer taxes and sales taxes on
building materials. The boom on Wall Street more than compensated for the
continued erosion of the State's (and the City's) manufacturing and maritime
base, since average wages in the finance, insurance and real estate sector and
related business and professional services were substantially higher (thereby
providing a net increase of higher incomes, taxed at even higher marginal
rates).
 
     During the calendar years 1984 through 1991, the State's rate of economic
expansion was somewhat slower than that of the nation as a whole. In the
1990-1991 national recession, the economy of the Northeast
 
                                       12
<PAGE>
region in general and the State in particular was more heavily damaged than that
of the rest of the nation and has been slower to recover.
 
     Although the national economy began to expand in 1991, the State economy
remained in recession until 1993, when employment growth resumed. Employment
growth has been hindered during recent years by significant cutbacks in the
computer and instrument manufacturing, utility and defense industries. Personal
income increased substantially in 1992 and 1993. The State's economy entered
into the third year of a slow recovery in 1995. Most of the growth occurred in
the trade, construction and service industries, with buisiness, social services
and health sectors accounting for most of the service industry growth. According
to assumptions contained in the State financial plan for FY1995-96 issued on
June 20, 1995 (the '1995-96 State Financial Plan'), employment is currently
projected to grow slightly during 1995, although the rate of increase is
expected to be below the rate experienced in 1994, due to cutbacks in
governmental spending and employment at all levels, as well as continued
corporate downsizing. The Mid-Year Update to the 1995-96 State Financial Plan
issued on October 26, 1995 (the 'Mid-Year Update') contains a marginally weaker
economic forecast than that contained in the initial 1995-96 State Financial
Plan, and predicts a significant slowing of state employment growth during
calendar year 1996, due to the forecasted, slackening pace of national economic
growth, industry consolidation and shrinking governmental employment.
 
     Notwithstanding the State budget for FY1995-96 which enacts significant tax
and program reductions, the State can expect to confront structural deficits in
future years. The 1995-96 State Financial Plan includes actions that will have
an effect on the budget outlook for FY1996-97 and beyond. In part, the 1995-96
State Financial Plan reflects actions which provide nonrecurring measures

(sometimes referred to as 'one-shots') variously estimated to provide $900
million to $1.0 billion of savings. Additionally, the three-year plan to reduce
State personal income taxes, as discussed below briefly, will decrease State tax
receipts by an estimated $1.7 billion in FY1996-97. Similarly, other actions
taken to reduce disbursements in the State's FY1995-96, such as reductions in
the State workforce and Medicaid and welfare expenditures, are expected to
provide greater reductions in future fiscal years. The net impact of these and
other factors is expected to produce a potential imbalance in receipts and
disbursements for State's FY1996-97 and future fiscal years.
 
     Further, there can be no assurance that the State economy will not
experience worse-than-predicted results in FY1995-96 with corresponding material
and adverse effects on the State's projections of receipts and disbursements.
Although the Mid-Year Update projects a continued balance in the 1995-96 State
Financial Plan, downward revisions have been made to estimates of both receipts
and disbursements. As the 1995-96 State Financial Plan and the Mid-Year Update
are each based upon forecasts of national and State economic activity it should
be noted that many uncertainties exist in such forecasts, including federal
financial and monetary policies, the availability of credit and the condition of
the world economy. In addition, the economic and financial condition of the
State may be affected by various financial, social, economic and political
factors. These factors can be complex, may vary from year to year and are
frequently the results of actions taken not only by the State and its agencies
and instrumentalities, but also by other entities, such as the federal
government, that are not under the control of the State.
 
     The fiscal health of the State may also be impacted by the fiscal health of
the City. Although the City has had a balanced budget since 1981, estimates of
the City's future revenues and expenditures are subject to various
uncertainties. For example, the effects of the October 1987 stock market crash
and the 1990-92 national recession have had a disproportionately adverse impact
on the New York City metropolitan region, as private sector job losses since
1989 have offset all the prior employment gains of the 1980s. Declines in both
employment and earnings in the finance sector contributed to declines in retail
sales and real estate values. In addition, a number of widely publicized
bankruptcies among highly leveraged retailing and brokerage
 
                                       13
<PAGE>
companies occurred. The effects of the recession have extended to banking,
insurance, business services (such as law, accounting and advertising),
publishing and communications. Factors which may inhibit the City's economic
recovery include (i) credit restraints imposed by the weak financial condition
of several major money center banks located in the City; (ii) increases in
combined State and local tax burdens, if uncompetitive tax rates are imposed;
(iii) perceived declines in the quality of life attributable to service
reductions and the deterioration of the City's infrastructure; (iv) additional
employment losses in the City's banking sector or corporate headquarters complex
due to further corporate relocations or restructurings; or (v) increased
expenditures for public assistance and health care. The City's future economic
condition will also likely be affected by its competitive position as a world
financial center (compared to London, Tokyo, Frankfurt and competing regional
U.S. centers). Investors should note that the budget for the City FY1995-96
addresses a projected $2.7 billion budget gap. Most of the budget-gap closing

initiatives may be implemented only with the cooperation of the City's municipal
unions, or the State or Federal governments. No assurance can be given that such
initiatives will be successfully undertaken.
 
     While the State's economy is broader-based than that of the City,
particular industries are concentrated in and have a disproportionate impact on
certain areas, such as heavy industry in Buffalo, photographic and optical
equipment in Rochester, machinery and transportation equipment in Syracuse and
Utica-Rome, computers in Binghamton and in the Mid-Hudson Valley and electrical
equipment in the Albany-Troy-Schenectady area. Constraints on economic growth,
taxpayer resistance to proposed substantial increases in local tax rates, and
reductions in State aid in regions apart from the City have contributed to
financial difficulties for several county and other local governments.
 
     THE STATE.  As noted above, the financial condition of the State is
affected by several factors, including the strength of the State and its
regional economies, actions of the federal government, and State actions
affecting the level of receipts and disbursements. Owing to these and other
factors, the State may, in future years, face substantial potential budget gaps
resulting from a significant disparity between tax revenues projected from a
lower recurring receipts base and the future costs of maintaining State programs
at current levels.
 
     The State has been experiencing and continues to experience substantial
financial difficulties with General Fund (the principal operating account)
deficits incurred during FY1989-90 through FY1991-92. The State's accumulated
General Fund deficit (on a GAAP basis) grew 91% from FY1986-87 to FY1990-91, and
reached a then-record $6.265 billion (audited) by March 31, 1991. An accumulated
General Fund deficit at March 31, 1992 was restated to be $4.616 billion and at
March 31, 1993 was $2.551 billion. The State ended FY1993-94 with a negative
General Fund balance of $1.637 billion. This represented an improvement over
prior fiscal years, primarily due to an improving national and State economy
resulting in higher-than-expected receipts from personal income tax and various
business taxes and the relative success of the New York Local Government
Assistance Corporation ('LGAC'). The General Fund showed an operating surplus of
$914 million (on a GAAP basis). The State's budget for FY1994-95 was adopted on
June 8, 1994, more than two months after the beginning of the State's fiscal
year and has made all of the required quarterly revisions thereto as of the date
hereof. The State ended its FY1994-95 reporting a General Fund operating deficit
of $1.426 billion, primarily due to change in accounting methodologies used by
the State Comptroller and the use of $1.026 billion of the FY1993-94
cash-surplus to fund operating expenses in FY1994-95. These factors were offset
by net proceeds of $315 million of bonds issued by LGAC. Actual receipts
reported fell short of original projections, primarily in the categories of
business taxes. These shortfalls were offset by better than expected performance
in the remaining taxes, principally the user taxes and fees. Total expenditures
for FY1994-95 increased $2.083 billion, or 6.7% over the prior fiscal year.
 
                                       14
<PAGE>
     On June 7, 1995, the New York State legislature passed the final
legislation regarding the State's FY1995-96 budget. Both the enacted budget
bills and the State Financial Plan for FY1995-96 include the reductions in the
actual level of spending from that which occurred in FY1994-95 and project

reductions in Medicaid and State Authority operating costs. The FY1995-96 budget
also projects an approximate increase of 3% in all governmental funds over the
amounts received in FY1994-95 and includes the phase-in of a three-year
reduction in the State's personal income tax. The Governor released his proposed
budget for FY1996-97 on December 15, 1995 (the '1996-97 Executive Budget') 30
days in advance of the constitutionally-mandated release date. The 1996-97
Executive Budget projects a $3.9 billion budget gap, which it proposes to close
largely by Medicaid cost containment measures (approximately $1.0 billion),
welfare reform (approximately $240 million) and restructuring of the state
healthcare delivery system (approximately $470 million). The phased reduction of
the State's personal income tax is continued in the 1996-97 Executive Budget.
There are risks and uncertainties concerning whether or not certain tax and
spending cuts included in the FY1995-96 budget as adopted will be upheld if
challenged in the courts. For example, the State Comptroller is challenging the
proposed use of certain pension reserves. If such suit is successful,
approximately $110 million would become unavailable as a source of contribution
to the balanced State budget. Finally an additional $110 million in reductions
or from other sources may prove difficult. Additionally, even if all such tax
and spending cuts are successfully implemented, resulting in a balanced budget
for FY1995-96, there can be no assurance that the State will not face budget
gaps in future years, resulting from a disparity between tax revenues projected
from a lower recurring-receipts base and the spending required to maintain State
programs at current levels. Furthermore, the State is a party to numerous
lawsuits in which an adverse decision could require extraordinary expenditures.
Certain major budgetary considerations affecting the State are outlined below.
 
     REVENUE BASE.  The State's principal revenue sources are economically
sensitive, and include the personal income tax (53% of FY1994-95 and
approximately 54% of estimated FY1995-96 General Fund tax receipts,
respectively), user taxes and fees (20% of FY1994-95 and nearly 21% of estimated
FY1995-96 General Fund tax receipts) and business taxes (15% of both FY1994-95
and estimated FY1995-96 General Fund tax receipts, respectively). Uncertainties
in taxpayer behavior as a result of actual and proposed changes in Federal tax
law also may have an adverse impact on State tax receipts. One-fourth of the 4%
State sales tax has been dedicated to pay debt service of LGAC, and has
correspondingly reduced General Fund receipts. To the extent those moneys are
not necessary for payment to LGAC, they are transferred from the LGAC Tax Fund
to the General Fund and reported as a transfer from other funds rather than as a
sales and use tax receipts. During FY1991-1992, 1992-93, 1993-94 and 1994-95,
moneys were so transferred. Capital gains are a significant component of income
tax collections. Auto sales and building materials are significant components of
retail sales tax collections. Tax rates are relatively high and may impose
political and economic constraints on the ability of the State to further
increase its taxes. In 1995, the State enacted a tax-reduction program designed
to reduce, by 20 percent over three years, receipts from the personal income
tax. The tax had remained unchanged since 1989 as a result of annual deferrals
of tax reductions originally enacted in 1987. The tax-reduction program is
estimated to reduce receipts by $515 million in FY1995-96, $2.2 billion in
FY1996-97 and to produce further significant reductions in FY1997-98. In
addition to such reductions in overall tax rates, the tax-reduction program also
includes other modifications to the tax laws which will have the effect of
lowering the amount of tax revenues to be received by the State. In the absence
of countervailing economic growth or expenditure cuts the tax cuts could make
the achievement of a balanced State budget more difficult in future years. A

significant risk to the 1995-96 State Financial Plan arises from tax legislation
pending in the U.S. Congress. Changes to the federal tax treatment of capital
gains, if made, are likely to flow automatically to the State personal income
tax. Such changes, depending upon their precise character and
 
                                       15
<PAGE>
timing, as well as taxpayer response, could produce either revenue gain or loss
during the remainder of the State's 1995-96 fiscal year.
 
     STATE DEBT.  New York has the heaviest debt burden of any state (with
approximately $5.2 billion of general obligation, $4.7 billion of LGAC debt and
$18 billion of lease-purchase or other contractual debt outstanding as of March
31, 1995), and debt service costs absorb a large share of the State's budget. As
of March 31, 1995, the State is also obligated with respect to approximately
$7.0 billion for statutory moral obligations for nine of its Authorities and for
guarantees of $358 million of other Authority debt. Historically, the State has
had one of the largest seasonal financing requirements of any municipal issuer,
and was required each spring to borrow substantial sums in the credit markets to
finance its accumulated general fund deficit and its scheduled payments of aid
to local governments and school districts. In an effort to reduce such seasonal
borrowings, the State created LGAC as a financing vehicle to finance the State's
local assistance payments by issuing long-term debt, payable over 30 years from
a portion of the State sales tax (as discussed above). The State budget for
FY1995-96 and the 1995-96 State Financial Plan each proposed to utilize the
remainder of authorized but yet unissued LGAC bonds. As of June 1995, LGAC had
issued bonds and notes to provide net proceeds of $4.7 billion, thus completing
the LGAC program. The impact of LGAC's borrowing is that the State was able to
meet its cash flow needs in the first quarter of FY1995-96 without relying on
short-term seasonal borrowings. Neither the 1995-96 State Financial plan nor the
1994-95 State Financial Plan included a spring borrowing, the first time in 35
years that there was no short-term borrowing. Investors should note that the
enabling legislation for LGAC contains a covenant restricting the amount of the
State's spring borrowing, which may reduce the State's fiscal flexibility in
future years.
 
     BUDGETARY FLEXIBILITY.  A significant portion of the State's General Fund
budget is accounted for by contractually required expenses (such as pension and
debt service costs) and by federally mandated programs (such as AFDC and
Medicaid). In addition, State aid for school districts comprises a major share
of the budget, and total appropriations and distribution of such aid is
especially contentious politically. Furthermore, the State's ability to respond
to unanticipated developments in the future may have been impaired since the
State has utilized a substantial range of actions of a non-recurring nature in
recent years to finance its General Fund operations, including tapping excess
monies in special funds, refinancing outstanding debt to reduce reserve fund
requirements and current (but not long-term) debt service costs, recalculating
pension fund contributions, selling State assets, reimbursing past General Fund
expenditures by the issuance of authority debt and deferring payment for
expenditures to future fiscal years. The 1995-96 State Financial Plan contains
actions of a non-recurring nature including mergers of certain authorities,
payments from the sale of certain State assets and payments associated with the
resolution of certain court cases, totalling approximately $900 million to $1
billion. The 1996-97 Executive Budget, however, contains actions of a

non-recurring nature only to the extent of approximately $123 million.
 
     LABOR COSTS.  The State government workforce is mostly unionized, subject
to the Taylor Law which authorizes collective bargaining and prohibits (but has
not, historically, prevented) strikes and work slowdowns. Costs for employee
health benefits have increased substantially, and can be expected to further
increase. The State has a substantial unfunded liability for future pension
benefits, and has utilized changes in its pension fund investment return
assumptions to reduce current contribution requirements. If such investment
earnings assumptions are not sustained by actual results, additional State
contributions will be required in future years to meet the State's contractual
obligations. The State's change in actuarial method from the aggregate cost
method to a modified projected unit credit in FY1990-91 created a substantial
surplus that was amortized and applied to offset the State's contribution
through FY1993-94. This change in actuarial method was ruled unconstitutional by
the State's highest court and the State has returned to the aggregate
 
                                       16
<PAGE>
cost method in FY1994-95 using a four-year phase-in. Employer contributions,
including the State's, are expected to increase over the next five to ten years.
 
     PUBLIC ASSISTANCE.  New York has the second largest number of persons
receiving public assistance (AFDC and Home Relief) of any state. AFDC costs are
shared among the federal government, the State and its counties (including the
City) by statutory formula. Caseloads tend to rise significantly during economic
downturns, but have fallen only in the later stages of past economic recoveries.
 
     MEDICAID.  New York participates in the federal Medicaid program under a
state plan approved by the Health Care Financing Administration. The federal
government provides a substantial portion of eligible program costs, with the
remainder shared by the State and its counties (including the City). Basic
program eligibility and benefits are determined by federal guidelines, but the
State provides a number of optional benefits and expanded eligibility. Program
costs have increased substantially in recent years, and account for a rising
share of the State budget. Federal law requires that the State adopt
reimbursement rates for hospitals and nursing homes that are reasonable and
adequate to meet the costs that must be incurred by efficiently and economically
operated facilities in providing patient care, a standard that has led to past
litigation by hospitals and nursing homes seeking higher reimbursement from the
State. The budget adopted for FY1995-96 and, in particular, the 1996-97
Executive Budget includes reductions in spending for Medicaid. Cutbacks in State
spending for Medicaid may adversely affect the financial condition of hospitals
and health care institutions that are the obligors of bonds that may be held by
the Fund.
 
     THE STATE AUTHORITIES.  The State's Authorities are not subject to the
constitutional restrictions on the incurrence of debt which apply to the State
itself, and may issue bonds and notes within the amounts of, and as otherwise
restricted by, their legislative authorization. The New York State Public
Authorities Control Board approves the issuance of debt and major contracts by
10 of the Authorities. As of September 30, 1994 (the date of the latest data
available), there were 18 Authorities that had outstanding debt of $100 million
or more, the aggregate debt of which (including refunding bonds and moral

obligation, lease-purchase, contractual obligation or State-guaranteed debt)
then totaled approximately $70.3 billion. As of March 31, 1995, aggregate public
authority debt outstanding as State-supported debt was $27.9 billion and
State-related debt was $36.1 billion. In recent years, the State has provided
financial assistance through appropriations, in some cases of a recurring
nature, to certain Authorities for operating and other expenses and (from 1976
to 1987) in fulfillment of its commitments on moral obligation indebtedness or
otherwise, for debt service. The State budgeted operating assistance of
approximately $1.3 billion for the Metropolitan Transportation Authority ('MTA')
during FY1994-95 and estimates total State assistance in FY1995-96 to be
approximately $1.1 billion. This assistance is expected to continue to be
required (and may increase) in future years. Failure by the State to appropriate
necessary amounts or to take other action to permit the Authorities to meet
their obligations could adversely affect the ability of the State and the
Authorities to obtain financing in the public credit markets and the market
price of the State's outstanding bonds and notes.
 
     The MTA, whose credit rating was recently reduced, oversees the operation
of the City's subway and bus lines by its affiliates, the New York City Transit
Authority and the Manhattan and Bronx Surface Transit Operating Authority
(collectively, the 'TA'). MTA subsidiaries operate certain commuter rail and bus
lines in the New York metropolitan area. An affiliated agency, the Triborough
Bridge and Tunnel Authority ('TBTA'), operates certain intrastate toll bridges
and tunnels. To maintain its facilities and equipment, which deteriorated
significantly in the late 1970s due to deferred maintenance, the MTA prepares a
five year capital program subject to approval by the MTA Capital Program Review
Board. In April 1993, the State Legislature authorized the funding of a portion
of a five year $9.56 billion capital plan for the MTA for 1992 through 1996.
MTA's five year capital program for 1992-96 was approved by the State Capital
Program Review Board in
 
                                       17
<PAGE>
December 1993. There can be no assurance that all governmental actions for the
1992-96 Capital Program will be taken, that funding sources currently identified
will not be decreased or eliminated, or that the Capital Program will not be
delayed or reduced. If the Capital Program is delayed or reduced, ridership and
fare revenues may decline, which could impair the MTA's ability to meet its
operating expenses without additional State assistance. In addition, because
fares are not sufficient to finance its mass transit operations, the MTA has
depended and will continue to depend for operating support upon a system of
State, local government and TBTA support, and, to the extent available, Federal
assistance (including loans, grants and operating subsidies). There can be no
assurance that any such assistance will continue at any particular level or in
any fixed relationship to the operating costs and capital needs of the MTA.
 
     THE CITY.  The City has required, and continues to require significant
financial assistance from the State. The City depends on the State to enable the
City to balance its budget and meet its cash requirements. In the early 1970s,
the City incurred substantial operating deficits, and its financial controls,
accounting practices and disclosure policies were widely criticized. In 1975,
the City encountered severe financial difficulties and lost access to the public
credit markets. The State Legislature responded in 1975 by creating the
Municipal Assistance Corporation For The City of New York ('MAC') to provide

financing assistance for the City and the Financial Control Board to exercise
certain oversight and review functions with respect to the City's finances. The
Financial Control Board's powers over the City were suspended in June 1986, but
would be reinstated (under current law) if the City experiences certain adverse
financial circumstances. At the time of the fiscal crisis the State provided
substantial financial assistance to the City, the Federal government provided
the City with direct seasonal loans and guarantees on the City's long-term debt
and the City's labor unions accepted deferrals of wage increases and approved
purchases of City bonds by the pension funds. No assurance can be given that
similar assistance would again be made available if needed, particularly given
the current budgetary constraints faced by both the Federal and State
governments.
 
     The City provides services usually undertaken by counties, school districts
or special districts in other large urban areas, including the provision of
social services such as day care, foster care, health care, family planning,
services for the elderly and special employment services for needy individuals
and families who qualify for such assistance. State law requires the City to
allocate a large portion of its total budget to Board of Education operations,
and mandates that the City assume the local share of public assistance and
Medicaid costs. While the City has had GAAP operating surpluses in recent fiscal
years, the City has experienced growing financial difficulties, primarily
related to the impact of the recession on the local economy (reducing revenues
from most major taxes and increasing public assistance and Medicaid caseloads),
rising health care costs for City employees and for Medicaid and rising
inflation and interest rates. In response, the City implemented gap-closing
programs, which initially relied primarily on actions of a non-recurring nature,
but included substantial property tax rate increases and a personal income tax
surcharge imposed in FY1991 and selected service cutbacks. Reductions in State
aid, larger than budgeted labor settlements and increased police expenditures
added to the adverse budgetary impact of the local recession, confronting the
City with a potential $3.5 billion imbalance during FY1992 budget negotiations.
This initial budget gap was closed by adoption of a budget providing for various
tax increases and significant service reductions. Aid to nonprofit cultural
institutions in the City was significantly reduced (as was State aid to such
institutions), including certain institutions that are obligors of bonds that
may be held by the Fund.
 
     The City's budget for FY1993-94 identified measures to close a $300 million
budget gap, which was the result of shortfalls in federal and State aid from
previously projected levels. The City achieved balanced operating results as
reported in accordance with GAAP for FY1993-94. For FY1994-95, the City adopted
a budget which halted the trend in recent years of substantial increases in
City-funded spending from one year
 
                                       18
<PAGE>
to the next. The City budget adopted for FY1995-96 reduces City-funded spending
for the second consecutive year. Pursuant to State law, the City prepares a
four-year annual financial plan, which is reviewed and revised on a quarterly
basis and includes the City's capital, revenue and expense projections and
outlines proposed budget gap-closing programs for those years with projected
budget gaps. The mayor is responsible for preparing the City's four-year
financial plan including the City's current financial plan for the 1996 through

1999 fiscal years (the '1996-1999 Financial Plan'). The City's projections set
forth in the 1996-1999 Financial Plan are based on various assumptions and
contingencies which are uncertain and which may not materialize. Changes in
major assumptions could significantly effect the City's ability to balance its
budget and to meet its annual cash flow and financing requirements. Such
assumptions and contingencies include the timing and pace of a regional and
local economic recovery, increases in interest rates, the impact on real estate
tax revenues of the real estate market, wage increases for city employees
consistent with those assumed in the 1996-99 Financial Plan, employment growth,
the ability to implement proposed reductions in City personnel and other cost
reduction initiatives which may require in certain cases the cooperation of the
City's municipal unions, the ability of New York City Health and Hospitals
Corporation and the Board of Education to take actions to offset reduced
revenues, the ability to complete revenue generating transactions, provision of
State and federal aid and mandate relief, and the impact on City revenues of
proposals for federal and State welfare reform. No assurance can be given that
the assumptions used by the City in the 1996-1999 Financial Plan will be
realized. Furthermore, actions taken in recent fiscal years to avert deficits
may have reduced the City's flexibility in responding to future budgetary
imbalances, and have deferred certain expenditures to later fiscal years.
 
     The City's original budget for FY1994-95 reflected proposed actions to
eliminate a $2.3 billion budget gap. The City submitted on July 21, 1995 a
fourth quarter modification to the City's financial plan for FY1994-95 which
projects a balanced budget in accordance with GAAP for the City's FY1994-95. On
July 11, 1995, the City submitted the 1996-1999 Financial Plan, which is based
on the City's expense and capital budgets for the City's FY1995-96 adopted on
June 14, 1995 (the '1996 City Budget'). The 1996 City Budget sets forth proposed
actions by the City for FY1995-96 to close a substantial projected budget gap
(approximately $3.1 billion) resulting from lower than projected tax receipts
and other revenues and greater then projected expenditures. Proposed actions in
the 1996-1999 Financial Plan for the City's FY1995-96 include a reduction of
approximately $400 million primarily affecting public assistance and Medicaid
payments by the City, expenditure reductions in agencies totalling approximately
$1.2 billion and transitional labor savings of approximately $600 million. These
and other proposed actions were contained in the 1996-1999 Financial Plan as
well as the 1996 City Budget. The Budget is subject to the ability of the City
to implement the reductions in expenditures, personal services and personnel,
which are substantial and may be difficult to implement. For example, one of the
key items contained in the 1996 City Budget is the sale of the City's water
system for approximately $2.3 billion. This plan has been hotly contested since
it was announced, and is currently the focus of several lawsuits. In November,
the Mayor sued the City Comptroller to compel his signature on bonds needed to
accomplish the sale of the water system. The Comptroller had blocked the bond
sale, stating that the sale of City water assets would be illegal and 'an
improvident fiscal gimmick.' In December, a coalition of civic, housing and
environmental groups from New York City and Westchester County filed suit to
block the Mayor's plan to sell the Water System and announced an intention to
join in the Comptroller's battle to block the bond sale. In addition, certain
proposals may be offset by various State and federal legislation which could
mandate levels of City funding inconsistent with the 1996 City Budget and the
1996-1999 Financial Plan. In addition, the 1996-1999 Financial Plan anticipates
the receipt of substantial amounts of Federal aid. Certain proposed State and
federal actions are subject to legislative, the governor's and the president's

approvals, as applicable. Both federal and State actions are uncertain, certain
legislative
 
                                       19
<PAGE>
proposals contemplate significant reductions in federal spending, including
proposed federal welfare reform which could result in caps on, or block grants
of, federal programs. Further, no assurance can be given that either such
actions will in fact be taken or that the projected savings will result even if
such actions are taken.
 
     The City derives its revenues from a variety of local taxes, user charges,
miscellaneous revenues and federal and State unrestricted and categorical
grants. The City projects that local revenues will provide approximately 68.0%
of total revenues in FY1995-96 while federal aid, including categorical grants,
will provide 11.7% in FY1995-96 and State aid, including unrestricted aid and
categorical grants, will provide 20.3% in FY1995-96. As a proportion of total
revenues, State aid has remained relatively constant over the period from 1980
to 1990, while federal aid was sharply reduced (having provided nearly 20% of
total fiscal year 1980 revenues). The largest source of the City's revenues is
the real estate tax (approximately 22% of total revenues projected for
FY1995-96, at rates levied by the City council (subject to certain State
constitutional limits). the City derives the remainder of its tax revenues from
a variety of other economically sensitive local taxes (subject to authorization
by the legislature), including: a local sales and compensating use tax
(primarily dedicated to MAC debt service) imposed in addition to the State's
retail sales tax; the personal income tax on City residents and the earnings tax
on non-residents; a general corporation tax; and a financial corporation tax.
High tax burdens in the City impose political and economic constraints on the
ability of the City to increase local tax rates. The City's four-year financial
plans have been the subject of extensive public comment and criticism,
principally questioning the reasonableness of assumptions that the City will
have the capacity to generate sufficient revenues in the future to provide the
level of services contained in such City financial plans. On July 10, 1995, S&P
lowered the City's credit rating from A- to BBB+, among the lowest ratings of
any major city in the country. The rating agency cited specifically the City
budget's reliance on 'one-shot' measures to balance the budget for FY1995-96
without rectifying the underlying structural problems, its continued optimistic
projections of State and federal aid, and continued high debt levels.
 
     The City is the largest municipal debt issuer in the nation, and has more
than doubled its debt load since the end of FY1987-88, in large measure to
rehabilitate its extensive, aging physical plant. The City's seasonal borrowing
needs increased significantly during FY1989-90 and FY1990-91, largely due to
delayed State aid payments, and totalled $2.25 billion in FY1991-92, $1.40
billion in FY1992-93, $1.75 billion in FY1993-94 and $2.2 billion in FY1994-95.
Current projections forecast a need of $2.4 billion of seasonal financing for
FY1995-96. The City's current capital financing program reflects major
reductions (approximately $2.13 billion) in the size of the capital program to
be implemented cumulatively through FY1998-99 which is intended to reduce future
debt service requirements. Such reductions may adversely affect the condition of
the City's aging and deteriorating infrastructure and physical assets, such as
sewers, streets, bridges and tunnels, and mass transit facilities. Further, the
City's capital financing program currently contemplates receipt of proceeds of

approximately $1 billion resulting from the sale of the City's water system to
the Water Board, and proposes to utilize a substantial portion of such proceeds
for capital project improvements. It is not certain that such proceeds will
become available for capital improvements, because, as discussed above, the City
Comptroller has stated his opposition to such proposed transfer of the water
system.
 
     In November 1993, the voters approved a proposed charter whereby Staten
Island would secede from the City. Staten Island is one of five
counties/boroughs, comprising 4% of the City's population and 19% of its land
area. State law provides a complex mechanism for such secession.
 
     OTHER LOCALITIES.  Certain localities in addition to the City could have
financial problems which, if significant, could lead to requests for additional
State assistance during the State's FY1995-96 and thereafter. Fiscal
difficulties experienced by the City of Yonkers, for example, could result in
State actions to allocate State resources in amounts that cannot yet be
determined. In the recent past, the State provided substantial
 
                                       20
<PAGE>
financial assistance to its political subdivisions, totaling approximately 68%
of General Fund disbursements in the State's FY1992-93, 69% for FY1993-94, 70%
for FY1994-95 and estimated to account for 69% of General Fund disbursements in
FY1995-96, primarily for aid to elementary, secondary and higher education and
Medicaid and income maintenance and local transportation programs. The
Legislature enacted substantial reductions from previously budgeted levels of
State aid since December 1990. To the extent the State is constrained by its
financial condition, State assistance to localities may be further reduced,
compounding the serious fiscal constraints already experienced by many local
governments. Localities also face anticipated and potential problems resulting
from pending litigation (including challenges to local property tax
assessments), judicial decisions and socioeconomic trends.
 
     The total indebtedness of all localities in the State, other than New York
City, was approximately $17.7 billion as of the localities' fiscal years ending
during 1993 (the date of the latest data available). A small portion
(approximately $105 million) of this indebtedness represented borrowing to
finance budgetary deficits issued pursuant to enabling State legislation
(requiring budgetary review by the State Comptroller). Subsequently, certain
counties and other local governments have encountered significant financial
difficulties including the counties of Nassau, Suffolk, Monroe and Westchester
and the City of Buffalo. The State has imposed financial control on the City
from 1977 to 1986 and on the City of Yonkers since 1984 under an appointed
control board in response to fiscal crises encountered by such municipalities.
The Legislature imposed certain limited fiscal restraints on Nassau and Suffold
counties, and authorized their issuance of deficit bonds to finance over several
years their respective 1992 operating deficits.
 
INVESTMENT LIMITATIONS OF THE FUNDS
 
     CALIFORNIA TAX-FREE INCOME FUND AND NATIONAL TAX-FREE INCOME FUND. Neither
Fund may (1) issue senior securities or borrow money, except from banks for
emergency or temporary purposes, and then in an aggregate amount not in excess

of 10% of the value of the Fund's total assets at the time of such borrowing;
provided that the Fund will not purchase securities while borrowings in excess
of 5% of the value of the Fund's total assets are outstanding; (2) underwrite
securities of other issuers, except to the extent that, in connection with the
disposition of portfolio securities, the Fund may be deemed an underwriter under
federal securities laws; (3) purchase or sell real estate, provided that the
Fund may invest in municipal bonds secured by real estate or interests therein;
(4) purchase securities on margin, make short sales of securities or maintain a
short position, except that the Fund may make margin deposits, make short sales
and maintain short positions in connection with its use of options, futures
contracts and options on futures contracts; (5) purchase or sell commodities or
commodity contracts, except that the Fund may purchase or sell futures contracts
on municipal securities and on indexes of municipal securities and options
thereon; (6) invest in oil, gas or mineral exploration or development programs;
(7) purchase voting securities of any issuer or acquire securities of other
investment companies, except in connection with a merger, consolidation or
acquisition; (8) make loans, except through repurchase agreements, provided that
for purposes of this restriction the acquisition of municipal bonds or other
municipal debt obligations shall not be deemed to be the making of a loan; (9)
purchase any security if, as a result, 25% or more of the value of the Fund's
total assets would be invested in the securities of issuers having their
principal business activities in the same industry, except that this limitation
does not apply to municipal bonds; or (10) purchase the securities of any issuer
if as a result more than 5% of its total assets would be invested in the
securities of that issuer, provided that any securities issued or guaranteed by
the U.S. government, its agencies and instrumentalities are not subject to this
limitation and further provided that up to 25% of the value of the Fund's assets
may be invested without regard to this 5% limitation.
 
                                       21
<PAGE>
     For purposes of limitations (9) and (10) above, the District of Columbia,
Puerto Rico, each state or territory, 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 nongovernmental user, then such
nongovernmental user would be deemed to be the sole issuer. However, if in
either case the creating government or some other agency guarantees a security,
then to the extent that the value of all securities issued or guaranteed by such
government or entity exceeds 10% of a Fund's total assets, such a guarantee
would be considered a separate security and would be treated as an issue of such
government or other agency.
 
     It is possible that either California Tax-Free Income Fund or National
Tax-Free Income Fund from time to time will invest more than 25% of its assets
in a particular segment of the municipal securities market, such as hospital
revenue bonds, housing agency bonds, IDBs, PABs or airport bonds or in
securities the interest upon which is paid from revenues of a similar type of
project. In such circumstances, economic, business, political or other changes
affecting one bond might also affect other bonds in the same segment, thereby

potentially increasing market risk.
 
     The foregoing investment limitations cannot be changed for California
Tax-Free Income Fund or National Tax-Free Income Fund without the affirmative
vote of the lesser of (1) more than 50% of the outstanding shares of the
applicable 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, later changes in percentage resulting from
a change in values of portfolio securities or the amount of total assets will
not be considered a violation of any of the foregoing limitations.
 
     The following investment restrictions may be changed by PaineWebber Mutual
Fund Trust's board of trustees without shareholder approval: Each of California
Tax-Free Income Fund and National Tax-Free Income Fund will not (1) purchase any
security if as a result of such purchase more than 5% of its assets would be
invested in securities with respect to which payment of interest and principal
are the responsibility of a company, including its predecessors, with less than
three years operating history; (2) invest more than 10% of its net assets in
illiquid securities, a term which means securities that cannot be disposed of
within seven days in the ordinary course of business at approximately the amount
at which the Fund has valued the securities and includes, among other things,
repurchase agreements maturing in more than seven days; (3) make investments in
warrants if such investments, valued at the lower of cost or market, exceed 5%
of the value of its net assets, which amount may include warrants that are not
listed on the New York Stock Exchange, Inc. ('NYSE') or the American Stock
Exchange, Inc. ('AMEX'), provided that such unlisted warrants, valued at the
lower of cost or market, do not exceed 2% of the Fund's net assets and further
provided that restriction does not apply to warrants attached to, or sold as a
unit with, other securities; (4) purchase or retain the securities of any issuer
if the officers and trustees of the Fund and the officers and directors of
Mitchell Hutchins (each owning beneficially more than 0.5% of the outstanding
securities of an issuer) own in the aggregate more than 5% of the securities of
an issuer; or (5) invest more than 35% of its total assets in debt securities
rated Ba or lower by Moody's or BB or lower by S&P (or determined by Mitchell
Hutchins to be of comparable quality). This non-fundamental policy (5) can be
changed only upon 30 days' advance notice to shareholders. Each Fund will
continue to interpret fundamental investment limitation (3) to prohibit
investment in real estate limited partnerships.

<PAGE>
     MUNICIPAL HIGH INCOME FUND AND NEW YORK TAX-FREE INCOME FUND.  Neither Fund
may (1) issue senior securities or borrow money, except from banks for temporary
purposes, provided that the aggregate amount borrowed does not exceed 10% of the
total asset value of the Fund at the time of such borrowing and further provided
that the Fund will not purchase securities while borrowings in excess of 5% of
its total assets are outstanding; (2) underwrite securities of other issuers,
except to the extent that, in connection with the purchase of municipal
securities directly from an issuer thereof in accordance with the Fund's
investment objective, policies and limitations or the disposition of portfolio
securities, the Fund may be deemed to be an underwriter; (3) purchase or sell
real estate, except that the Fund may invest in municipal securities secured by
real estate or interests therein; (4) purchase securities on margin, make short

sales of securities or maintain a short position, except that the Fund may (a)
make margin deposits, make short sales and maintain short positions in
connection with its use of options, futures contracts and options on futures
contracts and (b) sell short 'against the box'; (5) purchase or sell commodities
or commodity contracts, except that the Fund may purchase or sell futures
contracts on municipal securities and on indexes of municipal securities and
options thereon; (6) invest in oil, gas or mineral exploration or development
programs; (7) purchase voting securities of any issuer or acquire securities of
other investment companies, except in connection with a merger, consolidation or
acquisition and except to the extent permitted by Section 12 of the Investment
Company Act of 1940 ('1940 Act') (currently, up to 10% of the total assets of
the Fund and no more than 5% of total assets in any single investment company
and no more than 3% of the total outstanding voting stock of any one investment
company); (8) make loans, except through repurchase agreements; provided that
for purposes of this restriction the acquisition of publicly distributed
municipal securities and other publicly distributed debt obligations shall not
be deemed to be the making of a loan; and (9) purchase any security if, as a
result, 25% or more of the value of the Fund's total assets would be invested in
the securities of issuers having their principal business activities in the same
industry, except that this limitation does not apply to municipal securities or
securities issued or guaranteed by the U.S. government, its agencies and
instrumentalities.
 
     For purposes of limitation (9), the District of Columbia, Puerto Rico, each
state or territory, each public 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 nongovernmental user, then such nongovernmental
user would be deemed to be the sole issuer. However, if in either case the
creating government or some other agency guarantees a security, such a guarantee
would be considered a separate security and would be treated as an issuer of
such government or other agency. While limitation (4) permits each Fund to sell
short 'against the box' and limitation (7) permits each Fund to invest up to 10%
of its total assets in the securities of other investment companies, neither
Fund has any present intention of engaging in these practices.
 
     It is possible that either Municipal High Income Fund or New York Tax-Free
Income Fund from time to time will invest more than 25% of its total assets in a
particular segment of the municipal securities market, such as hospital revenue
bonds, housing agency bonds, IDBs, PABs or airport bonds or in securities the
interest upon which is paid from revenues of a similar type of project. In such
circumstances, economic, business, political or other changes affecting one bond
might also affect other bonds in the same segment, thereby potentially
increasing market risk.

     The foregoing fundamental investment limitations cannot be changed for
Municipal High Income Fund or New York Tax-Free Income Fund without the
affirmative vote of the lesser of (a) more than 50% of the outstanding shares of

the applicable Fund or (b) 67% or more of such 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 foregoing limitations.
 
     The following investment restrictions may be changed by PaineWebber
Municipal Series' board of trustees with respect to a Fund without shareholder
approval: Each of Municipal High Income Fund and New York Tax-Free Income Fund
may not (1) purchase any security if as a result of such purchase more than 5%
of its assets would be invested in securities with respect to which payment of
interest and principal are the responsibility of a company, including its
predecessors, with less than three years operating history; (2) invest more than

trustees of the Trust and the officers and directors of Mitchell Hutchins (each
owning beneficially more than 0.5% of the outstanding securities of an issuer)
own in the aggregate more than 5% of the securities of the issuer; and (4) make
investments in warrants if such investments, valued at the lower of cost or
market, exceed 5% of the value of its net assets, which amount may include
warrants that are not listed on the NYSE or the AMEX, provided that such
unlisted warrants, valued at the lower of cost or market, do not exceed 2% of
the Fund's net assets and further provided that this restriction does not apply
to warrants attached to, or sold as a unit with, other securities. In addition,
New York Tax-Free Income Fund may not invest more than 35% of its total assets
in debt securities rated Ba or lower by Moody's or BB or lower by S&P (or
determined by Mitchell Hutchins to be of comparable quality). This
non-fundamental policy can be changed only upon 30 days' advance notice to

     Each Fund will continue to interpret fundamental investment limitation (3)
to prohibit investment in real estate limited partnerships.

                     HEDGING AND RELATED INCOME STRATEGIES
 
     As discussed in the Prospectus, Mitchell Hutchins may use a variety of
financial instruments ('Hedging Instruments'), including certain options,
futures contracts (sometimes referred to as 'futures') and options on futures
contracts, to attempt to hedge the Funds' portfolios and may use options to
attempt to enhance the Fund's income. The particular Hedging Instruments are
described in the Appendix to this Statement of Additional Information. Because
each Fund intends to use options and futures for hedging purposes, each Fund may
enter into options and futures transactions that approximate (but do not exceed)
the full value of its portfolio. However, no Fund currently intends to engage in
hedging or related income strategies. Any income realized from the use of
options and futures would be taxable to shareholders; therefore, a Fund would
engage in hedging or related income strategies only under unusual market

conditions. The use of options and futures solely to enhance income may be
considered a form of speculation.
 
     Hedging strategies can be broadly categorized as 'short hedges' and 'long
hedges.' A short hedge is a purchase or sale of a Hedging Instrument intended to
partially or fully offset potential declines in the value of one or more
investments held in a Fund's portfolio. Thus, in a short hedge a Fund takes a
position in a Hedging Instrument whose price is expected to move in the opposite
direction of the price of the investment being hedged. For example, a Fund might
purchase a put option on a security to hedge against a potential decline in the
value of that security. If the price of the security declined below the exercise
price of the put, the Fund could exercise the put and thus limit its loss below
the exercise price to the premium paid plus transaction costs. In the
alternative, because the value of the put option can be expected to increase as
the value of the underlying security declines, the Fund might be able to close
out the put option and realize a gain to offset the decline in the value of the
security.
 
     Conversely, a long hedge is a purchase or sale of a Hedging Instrument
intended partially or fully to offset potential increases in the acquisition
cost of one or more investments that a Fund intends to acquire. Thus, in a long
hedge a Fund takes a position in a Hedging Instrument whose price is expected to
move in the same direction as the price of the prospective investment being
hedged. For example, a Fund might purchase a call option on a security it
intends to purchase in order to hedge against an increase in the cost of the
security. If the price of the security increased above the exercise price of the
call, the Fund could exercise the call and thus limit its acquisition cost to
the exercise price plus the premium paid and transaction costs. Alternatively,
the Fund might be able to offset the price increase by closing out an
appreciated call option and realizing a gain.
 
     Hedging Instruments on securities generally are used to hedge against price
movements in one or more particular securities positions that a Fund owns or
intends to acquire. Hedging Instruments on debt securities may be used to hedge
either individual securities or broad fixed income market sectors.
 
     The use of Hedging Instruments is subject to applicable regulations of the
Securities and Exchange Commission ('SEC'), the several options and futures
exchanges upon which they are traded, the Commodity Futures Trading Commission
('CFTC') and various state regulatory authorities. In addition, a Fund's ability
to use Hedging Instruments will be limited by tax considerations. See 'Taxes.'
 
     In addition to the products, strategies and risks described below, Mitchell
Hutchins expects to discover additional opportunities in connection with
options, futures contracts and other hedging techniques. These new opportunities
may become available as Mitchell Hutchins develops new techniques, as regulatory
authorities broaden the range of permitted transactions and as new options,
futures contracts or other techniques are developed. Mitchell Hutchins may
utilize these opportunities to the extent that they are
 
                                       25
<PAGE>
consistent with the Funds' investment objectives and permitted by the Funds'
investment limitations and applicable regulatory authorities. The Funds'

Prospectus or Statement of Additional Information will be supplemented to the
extent that new products or techniques involve materially different risks than
those described below or in the Prospectus.
 
     SPECIAL RISKS OF HEDGING STRATEGIES.  The use of Hedging Instruments
involves special considerations and risks, as described below. Risks pertaining
to particular Hedging Instruments are described in the sections that follow.
 
     (1) Successful use of most Hedging Instruments depends upon Mitchell
Hutchins' ability to predict movements of the overall securities and interest
rate markets, which requires different skills than predicting changes in the
prices of individual securities. While Mitchell Hutchins is experienced in the
use of Hedging Instruments, there can be no assurance that any particular
hedging strategy adopted will succeed.
 
     (2) There might be imperfect correlation, or even no correlation, between
price movements of a Hedging Instrument and price movements of the investments
being hedged. For example, if the value of a Hedging Instrument used in a short
hedge increased by less than the decline in value of the hedged investment, the
hedge would not be fully successful. Such a lack of correlation might occur due
to factors unrelated to the value of the investments being hedged, such as
speculative or other pressures on the markets in which Hedging Instruments are
traded. The effectiveness of hedges using Hedging Instruments on indices will
depend on the degree of correlation between price movements in the index and
price movements in the securities being hedged.
 
     (3) Hedging strategies, if successful, can reduce risk of loss by wholly or
partially offsetting the negative effect of unfavorable price movements in the
investments being hedged. However, hedging strategies can also reduce
opportunity for gain by offsetting the positive effect of favorable price
movements in the hedged investments. For example, if a Fund entered into a short
hedge because Mitchell Hutchins projected a decline in the price of a security
in the Fund's portfolio, and the price of that security increased instead, the
gain from that increase might be wholly or partially offset by a decline in the
price of the Hedging Instrument. Moreover, if the price of the Hedging
Instrument declined by more than the increase in the price of the security, the
Fund could suffer a loss. In either such case, the Fund would have been in a
better position had it not hedged at all.
 
     (4) As described below, a Fund might be required to maintain assets as
'cover,' maintain segregated accounts or make margin payments when it takes
positions in Hedging Instruments involving obligations to third parties (i.e.,
Hedging Instruments other than purchased options). If a Fund were unable to
close out its positions in such Hedging Instruments, it might be required to
continue to maintain such assets or accounts or make such payments until the
position expired or matured. These requirements might impair a Fund's ability to
sell a portfolio security or make an investment at a time when it would
otherwise be favorable to do so, or require that a Fund sell a portfolio
security at a disadvantageous time. A Fund's ability to close out a position in
a Hedging Instrument prior to expiration or maturity depends on the existence of
a liquid secondary market or, in the absence of such a market, the ability and
willingness of a contra party to enter into a transaction closing out the
position. Therefore, there is no assurance that any hedging position can be
closed out at a time and price that is favorable to the Fund.

 
     COVER FOR HEDGING STRATEGIES.  Transactions using Hedging Instruments,
other than purchased options, expose a Fund to an obligation to another party. A
Fund will not enter into any such transactions unless it owns either (1) an
offsetting ('covered') position in securities or other options or futures
contracts or
 
                                       26
<PAGE>
(2) cash and short-term liquid debt securities, with a value sufficient at all
times to cover its potential obligations to the extent not covered as provided
in (1) above. Each Fund will comply with SEC guidelines regarding cover for
hedging transactions and will, if the guidelines so require, set aside cash,
U.S. government securities or other liquid, high-grade debt securities in a
segregated account with its custodian in the prescribed amount.
 
     Assets used as cover or held in a segregated account cannot be sold while
the position in the corresponding Hedging Instrument is open, unless they are
replaced with similar assets. As a result, the commitment of a large portion of
a Fund's assets to cover or segregated accounts could impede portfolio
management or the Fund's ability to meet redemption requests or other current
obligations.
 
     OPTIONS.  The Funds may purchase put and call options, and write (sell)
covered put and call options, on debt securities. The purchase of call options
serves as a long hedge, and the purchase of put options serves as a short hedge.
Writing covered put or call options can enable a Fund to enhance income by
reason of the premiums paid by the purchasers of such options. However, if the
market price of the security underlying a covered put option declines to less
than the exercise price of the option, minus the premium received, the Fund
would expect to suffer a loss. Writing covered call options serves as a limited
short hedge, because declines in the value of the hedged investment would be
offset to the extent of the premium received for writing the option. However, if
the security appreciates to a price higher than the exercise price of the call
option, it can be expected that the option will be exercised and the Fund will
be obligated to sell the security at less than its market value. If the covered
call option is an OTC option, the securities or other assets used as cover would
be considered illiquid to the extent described under 'Investment Policies and
Restrictions--Illiquid Securities.'
 
     The value of an option position will reflect, among other things, the
current market value of the underlying investment, the time remaining until
expiration, the relationship of the exercise price to the market price of the
underlying investment, the historical price volatility of the underlying
investment and general market conditions. Options normally have expiration dates
of up to nine months. Generally, OTC options on debt securities are European
style options. This means that the option is only exercisable immediately prior
to its expiration. This is in contrast to American-style options, which are
exercisable at any time prior to the expiration date of the option. Options that
expire unexercised have no value.
 
     A Fund may effectively terminate its right or obligation under an option by
entering into a closing transaction. For example, a Fund may terminate its
obligation under a call or put option that it had written by purchasing an

identical call or put option; this is known as a closing purchase transaction.
Conversely, a Fund may terminate a position in a put or call option it had
purchased by writing an identical put or call option; this is known as a closing
sale transaction. Closing transactions permit a Fund to realize profits or limit
losses on an option position prior to its exercise or expiration.
 
     The Funds may purchase or write both exchange-traded and OTC options.
However, exchange-traded or liquid OTC options on municipal debt securities are
not currently available. Exchange markets for options on debt securities exist
but are relatively new, and these instruments are primarily traded on the OTC
market. Exchange-traded options in the United States are issued by a clearing
organization affiliated with the exchange on which the option is listed which,
in effect, guarantees completion of every exchange-traded option transaction. In
contrast, OTC options are contracts between the Fund and its contra party
(usually a securities dealer or a bank) with no clearing organization guarantee.
Thus, when the Fund purchases or writes an OTC option, it relies on the contra
party to make or take delivery of the underlying investment upon exercise of the
option. Failure by the contra party to do so would result in the loss of any
premium paid by the Fund as well as
 
                                       27
<PAGE>
the loss of any expected benefit of the transaction. The Funds will enter into
OTC option transactions only with contra parties that have a net worth of at
least $20 million.
 
     A Fund's ability to establish and close out positions in exchange-listed
options depends on the existence of a liquid market. Each Fund intends to
purchase or write only those exchange-traded options for which there appears to
be a liquid secondary market. However, there can be no assurance that such a
market will exist at any particular time. Closing transactions can be made for
OTC options only by negotiating directly with the contra party, or by a
transaction in the secondary market if any such market exists. Although a Fund
will enter into OTC options only with contra parties that are expected to be
capable of entering into closing transactions with the Fund, there is no
assurance that the Fund will in fact be able to close out an OTC option position
at a favorable price prior to expiration. In the event of insolvency of the
contra party, the Fund might be unable to close out an OTC option position at
any time prior to its expiration.
 
     If a Fund were unable to effect a closing transaction for an option it had
purchased, it would have to exercise the option to realize any profit. The
inability to enter into a closing purchase transaction for a covered call option
written by a Fund could cause material losses because the Fund would be unable
to sell the investment used as cover for the written option until the option
expires or is exercised.
 
     In the event that options on indices of municipal and non-municipal debt
securities become available, a Fund may purchase and write put and call options
on such indices in much the same manner as the more traditional options
discussed above, except that index options may serve as a hedge against overall
fluctuations in the debt securities markets (or market sectors) rather than
anticipated increases or decreases in the value of a particular security.
 

     GUIDELINES FOR OPTIONS.  A Fund's use of options is governed by the
following guidelines, which can be changed by each Trust's board of trustees
without shareholder vote:
 
          1. A Fund may purchase a put or call option, including any straddles
     or spreads, only if the value of its premium, when aggregated with the
     premiums on all other options held by the Fund, does not exceed 5% of the
     Fund's total assets.
 
          2. The aggregate value of securities underlying put options written by
     any Fund determined as of the date the put options are written, will not
     exceed 50% of the Fund's net assets.
 
          3. The aggregate premiums paid on all options (including options on
     securities and indices of debt securities and options on futures contracts)
     purchased by the Fund that are held at any time will not exceed 20% of the
     Fund's net assets.
 
     FUTURES.  The Funds may purchase and sell municipal bond index futures
contracts, municipal debt futures contracts and purchase put and call options,
and write covered put and call options, on such futures contracts. The purchase
of futures or call options thereon can serve as a long hedge, and the sale of
futures or the purchase of put options thereon can serve as a short hedge.
Writing covered call options on futures contracts can serve as a limited short
hedge, and writing covered put options on futures contracts can serve as a
limited long hedge, using a strategy similar to that used for writing covered
call options on securities or indices.
 
     Futures strategies also can be used to manage the average duration of a
Fund's portfolio. If Mitchell Hutchins wishes to shorten the average duration of
a Fund, the Fund may sell a futures contract or a call option thereon, or
purchase a put option on that futures contract. If Mitchell Hutchins wishes to
lengthen the
 
                                       28
<PAGE>
average duration of a Fund, the Fund may buy a futures contract or a call option
thereon, or sell a put option thereon.
 
     No price is paid upon entering into a futures contract. Instead, at the
inception of a futures contract a Fund is required to deposit in a segregated
account with its custodian, in the name of the futures broker through whom the
transaction was effected, 'initial margin' consisting of cash, U.S. government
securities or other liquid, high-grade debt securities, in an amount generally
equal to 10% or less of the contract value. Margin must also be deposited when
writing a call option on a futures contract, in accordance with applicable
exchange rules. Unlike margin in securities transactions, initial margin on
futures contracts does not represent a borrowing, but rather is in the nature of
a performance bond or good-faith deposit that is returned to the Fund at the
termination of the transaction if all contractual obligations have been
satisfied. Under certain circumstances, such as periods of high volatility, the
Fund may be required by an exchange to increase the level of its initial margin
payment, and initial margin requirements might be increased generally in the
future by regulatory action.

 
     Subsequent 'variation margin' payments are made to and from the futures
broker daily as the value of the futures position varies, a process known as
'marking to market.' Variation margin does not involve borrowing, but rather
represents a daily settlement of the Fund's obligations to or from a futures
broker. When a Fund purchases an option on a future, the premium paid plus
transaction costs is all that is at risk. In contrast, when a Fund purchases or
sells a futures contract or writes a call or put option thereon, it is subject
to daily variation margin calls that could be substantial in the event of
adverse price movements. If the Fund has insufficient cash to meet daily
variation margin requirements, it might need to sell securities at a time when
such sales are disadvantageous.
 
     Holders and writers of futures positions and options on futures can enter
into offsetting closing transactions, similar to closing transactions on
options, by selling or purchasing, respectively, an instrument identical to the
instrument held or written. Positions in futures and options on futures may be
closed only on an exchange or board of trade that provides a secondary market.
Each Fund intends to enter into futures transactions only on exchanges or boards
of trade where there appears to be a liquid secondary market. However, there can
be no assurance that such a market will exist for a particular contract at a
particular time.
 
     Under certain circumstances, futures exchanges may establish daily limits
on the amount that the price of a future or related option can vary from the
previous day's settlement price; once that limit is reached, no trades may be
made that day at a price beyond the limit. Daily price limits do not limit
potential losses because prices could move to the daily limit for several
consecutive days with little or no trading, thereby preventing liquidation of
unfavorable positions.
 
     If a Fund were unable to liquidate a futures or related options position
due to the absence of a liquid secondary market or the imposition of price
limits, it could incur substantial losses. The Fund would continue to be subject
to market risk with respect to the position. In addition, except in the case of
purchased options, the Fund would continue to be required to make daily
variation margin payments and might be required to maintain the position being
hedged by the future or option or to maintain cash or securities in a segregated
account.
 
     Certain characteristics of the futures market might increase the risk that
movements in the prices of futures contracts or related options might not
correlate perfectly with movements in the prices of the investments being
hedged. For example, all participants in the futures and related options markets
are subject to daily variation margin calls and might be compelled to liquidate
futures or related options positions whose prices are moving unfavorably to
avoid being subject to further calls. These liquidations could increase price
 
                                       29
<PAGE>
volatility of the instruments and distort the normal price relationship between
the futures or options and the investments being hedged. Also, because initial
margin deposit requirements in the futures market are less onerous than margin
requirements in the securities markets, there might be increased participation

by speculators in the futures markets. This participation also might cause
temporary price distortions. In addition, activities of large traders in both
the futures and securities markets involving arbitrage, 'program trading' and
other investment strategies might result in temporary price distortions.
 
     GUIDELINES FOR FUTURES AND RELATED OPTIONS.  A Fund's use of futures and
related options is governed by the following guidelines, which can be changed by
each Trust's board of trustees without shareholder vote:
 
          1. To the extent a Fund enters into futures contracts and options on
     futures positions that are not for bona fide hedging purposes (as defined
     by the CFTC), the aggregate initial margin and premiums on those positions
     (excluding the amount by which options are 'in-the-money') may not exceed
     5% of the Fund's net assets.
 
          2. The aggregate premiums paid on all options (including options on
     securities and indices of debt securities and options on futures contracts)
     purchased by any Fund that are held at any time will not exceed 20% of the
     Fund's net assets.
 
          3. The aggregate margin deposits on all futures contracts and options
     thereon held at any time by the Fund will not exceed 5% of the Fund's total
     assets.

     PaineWebber Mutual Fund Trust pays trustees who are not 'interested
persons' of the Trust ('disinterested trustees') $2,000 annually and PaineWebber
Municipal Series pays its disinterested trustees $3,000 annually. Each Trust
also pays its disinterested trustees $250 per meeting of the board or any
committee thereof. Trustees are reimbursed for any expenses incurred in
attending meetings. Trustees of each Trust who are 'interested persons' of the
Trust receive no compensation from the Trust. Trustees and officers of the
Trusts own in the aggregate less than 1% of the shares of each Fund. Because
Mitchell Hutchins and PaineWebber perform substantially all of the services
necessary for the operation of the Trusts and the Funds, neither Trust requires
any employees. No officer, director or employee of Mitchell Hutchins or
PaineWebber presently receives any compensation from the Trusts for acting as a
trustee or officer. The table below includes certain information relating to the

compensation of each Trust's current trustees who held office during the fiscal
year ended February 28, 1995.

               INVESTMENT ADVISORY AND DISTRIBUTION ARRANGEMENTS
 
     INVESTMENT ADVISORY ARRANGEMENTS.  Mitchell Hutchins acts as the investment

PaineWebber Mutual Fund Trust, as supplemented by a Fee Agreement dated June 30,
1992 with respect to National Tax-Free Income Fund, and of Municipal High Income
Fund and New York Tax-Free Income Fund pursuant to a contract with PaineWebber
Municipal Series dated July 1, 1989 (each an 'Advisory Contract' and,
collectively, the 'Advisory Contracts'). Under the Advisory Contracts, each Fund
pays Mitchell Hutchins a fee, computed daily and paid monthly, at the annual
rate of 0.50% of the Fund's average daily net assets (0.60% of average daily net
assets in the case of Municipal High Income Fund and New York Tax-Free Income
Fund).
 
     Pursuant to their Advisory Contract and a substantially identical prior
contract, for the fiscal years ended February 28, 1995, February 28, 1994, the

fiscal period ended February 28, 1993 and the fiscal year ended November 30,
1992, California Tax-Free Income Fund paid (or accrued) to Mitchell Hutchins the
amounts of $1,340,491, $1,662,653, $376,199 and $1,330,101, respectively, and
National Tax-Free Income Fund paid (or accrued) to Mitchell Hutchins the amounts
of $2,891,059, $3,374,932, $695,966 and $2,136,708, respectively. Pursuant to
their Advisory Contract, for the fiscal years ended February 28, 1995, February
28, 1994 and February 28, 1993, Municipal High Income Fund paid (or accrued) to
Mitchell Hutchins the amounts of $768,555, $861,664 and $578,684 (of which
$138,010 was waived), respectively, and New York Tax-Free Income Fund paid (or
accrued) to Mitchell Hutchins the amounts of $481,509 (of which $10,398 was
waived), $557,864 (of which $202,282 was waived) and $338,232 (of which $334,763
was waived), respectively.
 
     Under a Service Agreement with each Trust that is reviewed by each Trust's
board of trustees annually, PaineWebber provides certain services to the Funds
not otherwise provided by the Fund's transfer agent. Pursuant to the Service
Agreement with PaineWebber Mutual Fund Trust, during the fiscal years ended
February 28, 1995, February 28, 1994, the fiscal period ended February 28, 1993
and the fiscal year ended November 30, 1992, California Tax-Free Income Fund
paid (or accrued) the amounts of $24,838, $26,755, $6,292 and $22,313,
respectively, and National Tax-Free Income Fund paid (or accrued) the amounts of
$64,620, $67,293, $14,710 and $47,399, respectively. Pursuant to the Service
Agreement with PaineWebber Municipal Series, during the fiscal years ended
February 25, 1995, February 28, 1994 and February 28, 1993, Municipal High
Income Fund paid (or accrued) the amounts of $19,534, $19,512 and $14,818 (of
which $12,855 was waived), respectively, and New York Tax-Free Income Fund paid
(or accrued) the amounts of $10,747 (of which $3,734 was waived), $9,492 (all of
which was waived) and $8,914 (all of which was waived), respectively.
 
     Under the terms of the applicable Advisory Contract, each Fund bears all
expenses incurred in its operation that are not specifically assumed by Mitchell
Hutchins. General expenses of the Trust not readily identifiable as belonging to
a particular Fund are allocated between the appropriate Funds by or under the
direction of the board of trustees in such manner as the board deems fair and
equitable. Expenses borne by each Fund include the following: (1) the cost
(including brokerage commissions, if any) of securities purchased or sold by the
Fund and any losses incurred in connection therewith; (2) fees payable to and
expenses incurred on behalf of the Fund by Mitchell Hutchins; (3) organizational
expenses; (4) filing fees and expenses relating to the registration and
qualification of the Fund's shares under federal and state securities laws and
maintenance of such registrations and qualifications; (5) fees and salaries
payable to trustees who are not interested persons of the Fund or Mitchell
Hutchins; (6) all expenses incurred in connection with the trustees' services,
including travel expenses; (7) taxes (including any income or franchise taxes)
and governmental fees; (8) costs of any liability, uncollectible items of
deposit and other insurance or fidelity bonds; (9) any costs,
 
                                       36
<PAGE>
expenses or losses arising out of a liability of or claim for damages or other
relief asserted against the Fund for violation of any law; (10) legal,
accounting and auditing expenses, including legal fees of special counsel for
the independent trustees; (11) charges of custodians, transfer agents and other
agents; (12) costs of preparing share certificates; (13) expenses of setting in

type and printing prospectuses and supplements thereto, statements of additional
information and supplements thereto, reports and proxy materials for existing
shareholders and costs of mailing such materials to existing shareholders; (14)
any extraordinary expenses (including fees and disbursements of counsel)
incurred by the Fund; (15) fees, voluntary assessments and other expenses
incurred in connection with membership in investment company organizations; (16)
costs of mailing and tabulating proxies and costs of meetings of shareholders,
the board and any committees thereof; (17) the cost of investment company
literature and other publications provided to trustees and officers; and (18)
costs of mailing, stationery and communications equipment.
 
     As required by state regulation, Mitchell Hutchins will reimburse a Fund if
and to the extent that the aggregate operating expenses of the Fund in any
fiscal year exceed applicable limits. Currently the most restrictive such limit
applicable to a Fund is 2.5% of the first $30 million of the Fund's average
daily net assets, 2.0% of the next $70 million of its average daily net assets
and 1.5% of its average daily net assets in excess of $100 million. Certain
expenses, such as brokerage commissions, taxes, interest, distribution fees and
extraordinary items, are excluded from this limitation. For the fiscal years
ended February 28, 1995, February 28, 1994, for the fiscal period ended February
28, 1993 and for the fiscal year ended November 30, 1992, PaineWebber and
Mitchell Hutchins were not required to reimburse either California Tax-Free
Income Fund or National Tax-Free Income Fund pursuant to state limitations. With
respect to Municipal High Income Fund and New York Tax-Free Income Fund,
substantially all the fee waivers referred to above were voluntary and not
required by state expense limitations. Mitchell Hutchins and/or PaineWebber
voluntarily reimbursed New York Tax-Free Income Fund the following amounts
during the fiscal years ended February 28, 1995, February 28, 1994 and February
28, 1993: none, none, and $104,834, respectively.
 
     Under each Advisory Contract, 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 Advisory Contract, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
Mitchell Hutchins in the performance of its duties or from reckless disregard of
its duties and obligations thereunder. Each Advisory Contract terminates
automatically upon its assignment and is terminable at any time without penalty
by the board of trustees or by vote of the holders of a majority of a Fund's
outstanding voting securities, on 60 days' written notice to Mitchell Hutchins
or by Mitchell Hutchins on 60 days' written notice to a Fund.
 
     The following table shows the approximate net assets as of December 31,
1995, sorted by category of investment objective, of the investment companies as
to which Mitchell Hutchins serves as adviser or sub-adviser. An investment
company may fall into more than one of the categories below.

     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 PaineWebber mutual funds and other
Mitchell Hutchins advisory clients.
 
     DISTRIBUTION ARRANGEMENTS. Mitchell Hutchins acts as the distributor of the
Class A, Class B and Class C shares of the Funds under separate distribution
contracts with each Trust dated July 7, 1993 and November 10, 1995
(collectively, 'Distribution Contracts'). Each Distribution Contract requires
Mitchell Hutchins to use its best efforts, consistent with its other businesses,
to sell shares of the applicable Funds. Shares of the Funds are offered
continuously. Under separate exclusive dealer agreements between Mitchell
Hutchins and PaineWebber dated July 7, 1993 and November 10, 1995, relating to
the Class A, Class B and Class C shares of each Fund (collectively, 'Exclusive
Dealer Agreements'), PaineWebber and its correspondent firms sell each Fund's
shares.
 
     Under separate plans of distribution pertaining to the Class A, Class B and
Class C shares of the Funds adopted by the Trusts in the manner prescribed under
Rule 12b-1 under the 1940 Act ('Class A Plan,' 'Class B Plan' and 'Class C
Plan,' collectively, 'Plans'), each Fund pays Mitchell Hutchins a service fee,
accrued daily and payable monthly, at the annual rate of 0.25% of the average
daily net assets of each Class of shares. Under the Class B Plan, each Fund also
pays Mitchell Hutchins a distribution fee, accrued daily and payable monthly, at
the annual rate of 0.75% of the average daily net assets of the Class B shares.
Under the Class C Plan, each Fund pays Mitchell Hutchins a distribution fee,
accrued daily and payable monthly, at the annual rate of 0.50% of the average
daily net assets of the Class C shares.
 
     Among other things, each Plan provides that (1) Mitchell Hutchins will
submit to the Trust's board of trustees at least quarterly, and the trustees
will review, reports regarding all amounts expended under the Plan and the
purposes for which such expenditures were made, (2) the Plan will continue in
effect only so long as it is approved at least annually, and any material
amendment thereto is approved, by the Trust's board of trustees, including those
trustees who are not 'interested persons' of the Trust and who have no direct or
indirect financial interest in the operation of the Plan or any agreement
related to the Plan, acting in person at a meeting called for that purpose, (3)

payments by a Fund under the Plan shall not be materially increased without the
affirmative vote of the holders of a majority of the outstanding shares of the
relevant Class of that Fund and (4) while the Plan remains in effect, the
selection and nomination of trustees who are not 'interested persons' of the
Trust shall be committed to the discretion of the trustees who are not
interested persons of the Trust.
 
     In reporting amounts expended under the Plans to the trustees, Mitchell
Hutchins will allocate expenses attributable to the sale of each Class of Fund
shares to such Class based on the ratio of sales of the shares of such Class to
the sales of all three Classes of shares. The fees paid by one Class of Fund
shares will not be used to subsidize the sale of any other Class of Fund shares.
 
     Under prior plans of distribution substantially similar to the Class A
Plan, each Fund paid Mitchell Hutchins a monthly distribution fee computed at
the same rate and in the same manner as the service fees under the Class A Plan.

  of its distribution fees. If such waivers had not been made, for the Class A,
  Class B and Class C shares the actual fees which would have been paid by the
  Fund would have been $90,781, $165,807 and $205,191, respectively, for New
  York Tax-Free Income Fund.
 
     Mitchell Hutchins estimates that it and its parent corporation,

     'Marketing and advertising' includes various internal costs allocated by
Mitchell Hutchins to its efforts at distributing Fund shares. These internal
costs encompass office rent, salaries and other overhead expenses of various
departments and areas of operations of Mitchell Hutchins. 'Branch network costs
allocated and interest expense' consist of an allocated portion of the expenses
of various PaineWebber departments involved in the distribution of each Fund's
shares, including the PaineWebber retail branch system.
 
     In approving each Fund's overall Flexible Pricing(Service Mark) system of
distribution, the Trust's board of trustees considered several factors,
including that implementation of Flexible Pricing would (1) enable investors to
choose the purchasing option best suited to their individual situation, thereby
encouraging current shareholders to make additional investments in the Fund and
attracting new investors and assets to the Fund to the benefit of the Fund and
its shareholders; (2) facilitate distribution of the Fund's shares; and (3)
maintain the competitive position of the Fund in relation to other funds that
have implemented or are seeking to implement similar distribution arrangements.
 
     In approving the Class A Plan for each Fund, the trustees considered all
the features of the distribution system, including (1) the conditions under
which initial sales charges would be imposed and the amount of such charges, (2)
Mitchell Hutchins' belief that the initial sales charge combined with a service
fee would be attractive to PaineWebber investment executives and correspondent
firms, resulting in greater growth of the Fund than might otherwise be the case,
(3) the advantages to the shareholders of economies of scale resulting from
growth in the Fund's assets and potential continued growth, (4) the services
provided to the Fund and its shareholders by Mitchell Hutchins, (5) the services
provided by PaineWebber pursuant to its Exclusive Dealer Agreement with Mitchell
Hutchins and (6) Mitchell Hutchins' shareholder service-related expenses and
costs.
 
     In approving the Class B Plan for each Fund, the trustees considered all
the features of the distribution system, including (1) the conditions under
which contingent deferred sales charges would be imposed and the amount of such
charges, (2) the advantage to investors in having no initial sales charges
deducted from Fund purchase payments and instead having the entire amount of
their purchase payments immediately invested in Fund shares, (3) Mitchell
Hutchins' belief that the ability of PaineWebber investment executives and

correspondent firms to receive sales commissions when Class B shares are sold
and continuing service fees thereafter while their customers invest their entire
purchase payments immediately in Class B shares would prove attractive to the
investment executives and correspondent firms, resulting in greater growth of
the Fund than might otherwise be the case, (4) the advantages to the
shareholders of economies of scale resulting from growth in the Fund's assets
and potential continued growth, (5) the services provided to the Fund and its
shareholders by Mitchell Hutchins, (6) the services provided by PaineWebber
pursuant to its Exclusive Dealer
 
                                       40
<PAGE>
Agreement with Mitchell Hutchins and (7) Mitchell Hutchins' shareholder service-
and distribution-related expenses and costs. The trustees also recognized that
Mitchell Hutchins' willingness to compensate PaineWebber and its investment
executives, without the concomitant receipt by Mitchell Hutchins of initial
sales charges, was conditioned upon its expectation of being compensated under
the Class B Plan.
 
     In approving the Class C Plan for each Fund, the trustees considered all
the features of the distribution system, including (1) the advantage to
investors in having no initial sales charges deducted from the Fund's purchase
payments and instead having the entire amount of their purchase payments
immediately invested in Fund shares, (2) the advantage to investors in being
free from contingent deferred sales charges upon redemption for shares held more
than one year and paying for distribution on an ongoing basis, (3) Mitchell
Hutchins' belief that the ability of PaineWebber investment executives and
correspondent firms to receive sales compensation for their sales of Class C
shares on an ongoing basis, along with continuing service fees, while their
customers invest their entire purchase payments immediately in Class C shares
and do not face contingent deferred sales charges, would prove attractive to the
investment executives and correspondent firms, resulting in greater growth to
the Fund than might otherwise be the case, (4) the advantages to the
shareholders of economies of scale resulting from growth in the Fund's assets
and potential continued growth, (5) the services provided to the Fund and its
shareholders by Mitchell Hutchins, (6) the services provided by PaineWebber
pursuant to its Exclusive Dealer Agreement with Mitchell Hutchins and (7)
Mitchell Hutchins' shareholder service- and distribution-related expenses and
costs. The trustees also recognized that Mitchell Hutchins' willingness to
compensate PaineWebber and its investment executives without the concomitant
receipt by Mitchell Hutchins of initial sales charges or contingent deferred
sales charges upon redemption, was conditioned upon its expectation of being
compensated under the Class C Plan.
 
     With respect to each Plan, the trustees considered all compensation that
Mitchell Hutchins would receive under the Plan and the Distribution Contract,
including service fees and, as applicable, initial sales charges, distribution
fees and contingent deferred sales charges. The trustees also considered the
benefits that would accrue to Mitchell Hutchins under each Plan in that Mitchell
Hutchins would receive service, distribution and advisory fees that are
calculated based upon a percentage of the average net assets of a Fund, which
fees would increase if the Plan were successful and the Fund attained and
maintained significant asset levels.
 

     Under the Distribution Contract between each Trust and Mitchell Hutchins
for the Class A shares and similar prior distribution contracts, for the fiscal
years and the fiscal period set forth below, Mitchell Hutchins earned the
following approximate amounts of sales charges and retained the following
approximate amounts, net of concessions to PaineWebber as exclusive dealer:

                             PORTFOLIO TRANSACTIONS
 
     Subject to policies established by each Trust's board of trustees, Mitchell
Hutchins is responsible for the execution of each Fund's portfolio transactions
and the allocation of brokerage transactions. In executing portfolio
transactions, Mitchell Hutchins seeks to obtain the best net results for a Fund,
taking into account such factors as the price (including the applicable dealer
spread or brokerage commission), size of order, difficulty of execution and
operational facilities of the firm involved. Each Fund effects its portfolio
transactions with municipal bond dealers. Municipal securities are traded on the
OTC market on a 'net' basis without a stated commission through dealers acting
for their own account and not as brokers. 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 that time. Since inception, the Funds have not paid any brokerage
commissions.
 
     For purchases or sales with broker-dealer firms which act as principal,
Mitchell Hutchins seeks best execution. Although Mitchell Hutchins may receive
certain research or execution services in connection with those 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 which could be
 
                                       42
<PAGE>
purchased for hard dollars. Mitchell Hutchins may engage in agency transactions
in OTC 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
have been if effected directly with a market-maker that did not provide research
or execution services. These procedures include Mitchell Hutchins receiving
multiple quotes from dealers before executing the transactions on an agency
basis.
 
     Information and research services furnished by dealers or brokers with or
through which the Funds effect securities transactions may be used by Mitchell
Hutchins in advising other funds or accounts and, conversely, research services
furnished to Mitchell Hutchins by dealers or brokers in connection with other
funds or accounts Mitchell Hutchins advises may be used by Mitchell Hutchins in
advising the Funds. Information and research received from such brokers or
dealers will be in addition to, and not in lieu of, the services required to be
performed by Mitchell Hutchins under the Advisory Contracts.
 
     Investment decisions for the Funds 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 such accounts. In
such cases, simultaneous transactions are inevitable. Purchases or sales are
then averaged as to price and allocated between the Fund involved 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 a 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.
 
     No Fund will purchase securities that are offered in underwritings in which
Mitchell Hutchins or any of its affiliates is a member of the underwriting or
selling group, except pursuant to procedures adopted by each Trust's board of
trustees pursuant to Rule 10f-3 under the 1940 Act. Among other things, these
procedures require that the commission or spread paid in connection with such a
purchase be reasonable and fair, that the purchase be at not more than the
public offering price prior to the end of the first business day after the date
of the public offering and that Mitchell Hutchins or any affiliate thereof not
participate in or benefit from the sale to a Fund.
 
     PORTFOLIO TURNOVER. Each Fund's annual portfolio turnover rate may vary
greatly from year to year, but it will not be a limiting factor when management
deems portfolio changes appropriate. The portfolio turnover rate is calculated
by dividing the lesser of a Fund's annual sales or purchases of portfolio
securities (exclusive of purchases or sales of securities whose maturities at
the time of acquisition were one year or less) by the monthly average value of
the securities in the portfolio during the year. For the fiscal years ended
February 28, 1995 and February 28, 1994, respectively, the portfolio turnover
rates for the Funds were: California Tax-Free Income Fund--10.61% and 36.73%;
National Tax-Free Income Fund--59.85% and 15.87%; Municipal High Income
Fund--28.44% and 23.19%; and New York Tax-Free Income Fund--6.30% and 8.14%.
 
           REDUCED SALES CHARGES, ADDITIONAL EXCHANGE AND REDEMPTION
                         INFORMATION AND OTHER SERVICES
 

     COMBINED PURCHASE PRIVILEGE-CLASS A SHARES. Investors and eligible groups
of related Fund investors may combine purchases of Class A shares of the Funds
with concurrent purchases of Class A shares of any other PaineWebber mutual fund
and thus take advantage of the reduced sales charges for Class A shares
indicated in the table of sales charges in the Prospectus. The sales charge
payable on the purchase of shares of
 
                                       43
<PAGE>
Class A shares of the Funds and Class A shares of such other funds will be at
the rates applicable to the total amount of the combined concurrent purchases.
 
     An 'eligible group of related Fund investors' can consist of any
combination of the following:
 
          (a) an individual, that individual's spouse, parents and children;
 
          (b) an individual and his or her Individual Retirement Account
     ('IRA');
 
          (c) an individual (or eligible group of individuals) and any company
     controlled by the individual(s) (a person, entity or group that holds 25%
     or more of the outstanding voting securities of a corporation will be
     deemed to control the corporation, and a partnership will be deemed to be
     controlled by each of its general partners);
 
          (d) an individual (or eligible group of individuals) and one or more
     employee benefit plans of a company controlled by the individual(s);
 
          (e) an individual (or eligible group of individuals) and a trust
     created by the individual(s), the beneficiaries of which are the individual
     and/or the individual's spouse, parents or children;
 
          (f) an individual and a Uniform Gifts to Minors Act/Uniform Transfers
     to Minors Act account created by the individual or the individual's spouse;
     or
 
          (g) an employer (or group of related employers) and one or more
     qualified retirement plans of such employer or employers (an employer
     controlling, controlled by or under common control with another employer is
     deemed related to that other employer).
 
          (h) individual accounts related together under one registered
     investment adviser having full discretion and control over the accounts.
     The registered investment adviser must communicate at least quarterly
     through a newsletter or investment update establishing a relationship with
     all of the accounts.
 
     RIGHTS OF ACCUMULATION-CLASS A SHARES. Reduced sales charges are available
through a right of accumulation, under which investors and eligible groups of
related Fund investors (as defined above) are permitted to purchase Class A
shares of the Funds among related accounts at the offering price applicable to
the total of (1) the dollar amount then being purchased plus (2) an amount equal
to the then-current net asset value of the purchaser's combined holdings of

Class A Fund shares and Class A shares of any other PaineWebber mutual fund. The
purchaser must provide sufficient information to permit confirmation of his or
her holdings, and the acceptance of the purchase order is subject to such
confirmation. The right of accumulation may be amended or terminated at any
time.
 
     WAIVERS OF SALES CHARGES-CLASS B SHARES. Among other circumstances, the
contingent deferred sales charge on Class B shares is waived where a total or
partial redemption is made within one year following the death of the
shareholder. The contingent deferred sales charge waiver is available where the
decedent is either the sole shareholder or owns the shares with his or her
spouse as a joint tenant with right of survivorship. This waiver applies only to
redemption of shares held at the time of death.
 
     Certain PaineWebber mutual funds offered shares subject to contingent
deferred sales charges before the implementation of the Flexible Pricing System
on July 1, 1991 ('CDSC Funds'). The contingent deferred sales charge is waived
with respect to redemptions of Class B shares of CDSC Funds purchased prior to
July 1, 1991 by officers, directors (trustees) or employees of the CDSC Funds,
Mitchell Hutchins or their affiliates (or their spouses and children under age
21). In addition, the contingent deferred sales charge will be reduced by 50%
with respect to redemptions of Class B shares of CDSC Funds purchased prior to
July 1, 1991 with a net asset value at the time of purchase of at least $1
million. If Class B shares of a CDSC Fund purchased prior to July 1, 1991 are
exchanged for Class B shares of a Fund, any waiver or reduction of the
contingent
 
                                       44
<PAGE>
deferred sales charge that applied to the Class B shares of the CDSC Fund will
apply to the Class B shares of the Fund acquired through the exchange.
 
     ADDITIONAL EXCHANGE AND REDEMPTION INFORMATION. As discussed in the
Prospectus, eligible shares of each Fund may be exchanged for shares of the
corresponding class of most other PaineWebber mutual funds. Shareholders will
receive at least 60 days' notice of any termination or material modification of
the exchange offer, except no notice need be given of an amendment whose only
material effect is to reduce the exchange fee, and no notice need be given if,
under extraordinary circumstances, either redemptions are suspended under the
circumstances described below or a Fund temporarily delays or ceases the sales
of its shares because it is unable to invest amounts effectively in accordance
with the Fund's investment objectives, policies and restrictions.
 
     If conditions exist that make cash payments undesirable, each Fund reserves
the right to honor any request for redemption by making payment in whole or in
part in securities chosen by the Fund and valued in the same way as they would
be valued for purposes of computing the Fund's net asset value. If payment is
made in securities, a shareholder may incur brokerage expenses in converting
these securities into cash. Each Trust has elected, however, to be governed by
Rule 18f-1 under the 1940 Act, under which a Fund is obligated to redeem shares
solely in cash up to the lesser of $250,000 or 1% of the net asset value of the
Fund during any 90-day period for one shareholder. This election is irrevocable
unless the SEC permits its withdrawal. A Fund may suspend redemption privileges
or postpone the date of payment during any period (1) when the NYSE is closed or

trading on the NYSE is restricted as determined by the SEC, (2) when an
emergency exists, as defined by the SEC, that makes it not reasonably
practicable for the Fund to dispose of securities owned by it or fairly to
determine the value of its assets or (3) as the SEC may otherwise permit. The
redemption price may be more or less than the shareholder's cost, depending on
the market value of a Fund's portfolio at the time.
 
     SYSTEMATIC WITHDRAWAL PLAN. On or about the 15th of each month for monthly
plans and on or about the 15th of the months selected for quarterly or
semi-annual plans, PaineWebber will arrange for redemption by a Fund of
sufficient shares to provide the withdrawal payment specified by participants in
the Fund's systematic withdrawal plan. The payment generally is mailed
approximately five business days after the redemption date. Withdrawal payments
should not be considered dividends, but redemption proceeds, with the tax
consequences described under 'Dividends and Taxes' in the Prospectus. If
periodic withdrawals continually exceed reinvested dividends, a shareholder's
investment may be correspondingly reduced. A shareholder may change the amount
of the systematic withdrawal or terminate participation in the plan at any time
without charge or penalty by written instructions with signatures guaranteed to
PaineWebber or the Transfer Agent. Instructions to participate in the plan,
change the withdrawal amount or terminate participation in the plan will not be
effective until five business days after written instructions with signatures
guaranteed are received by the Transfer Agent. Shareholders may request the
forms needed to establish a systematic withdrawal plan from their PaineWebber
investment executives, correspondent firms or the Transfer Agent at
1-800-647-1568.
 
     REINSTATEMENT PRIVILEGE-CLASS A SHARES. As described in the Prospectus,
shareholders who have redeemed their Class A shares may reinstate their account
in a Fund without a sales charge. Shareholders may exercise the reinstatement
privilege by notifying the Transfer Agent of such desire and forwarding a check
for the amount to be purchased within 365 days after the date of redemption. The
reinstatement will be made at the net asset value per share next computed after
the notice of reinstatement and check are received. The amount of a purchase
under this reinstatement privilege cannot exceed the amount of the redemption
proceeds. Gain on a redemption is taxable regardless of whether the
reinstatement privilege is exercised; however, a loss arising out of a
redemption will not be deductible to the extent the redemption proceeds are
 
                                       45
<PAGE>
reinvested, if the reinstatement privilege is exercised within 30 days after
redemption, and an adjustment will be made to the shareholder's tax basis for
the shares acquired pursuant to the reinstatement privilege. Gain or loss on a
redemption also will be adjusted for federal income tax purposes by the amount
of any sales charge paid on Class A shares, under the circumstances and to the
extent described below under 'Taxes'.
 
PAINEWEBBER RMA RESOURCE ACCUMULATION PLAN(SERVICE MARK);
 
PAINEWEBBER RESOURCE MANAGEMENT ACCOUNT(REGISTERED) (RMA(REGISTERED))
 
     Shares of the PaineWebber mutual funds (each a 'PW Fund' and, collectively,
the 'PW Funds') are available for purchase through the RMA Resource Accumulation

Plan ('Plan') by customers of PaineWebber and its correspondent firms who
maintain Resource Management Accounts ('RMA accountholders'). The Plan allows an
RMA accountholder to continually invest in one or more of the PW Funds at
regular intervals, with payment for shares purchased automatically deducted from
the client's RMA account. The client may elect to invest at monthly or quarterly
intervals and may elect either to invest a fixed dollar amount (minimum $100 per
period) or to purchase a fixed number of shares. A client can elect to have Plan
purchases executed on the first or fifteenth day of the month. Settlement occurs
three Business Days (defined under 'Valuation of Shares') after the trade date,
and the purchase price of the shares is withdrawn from the investor's RMA
account on the settlement date from the following sources and in the following
order: uninvested cash balances, balances in RMA money market funds, or margin
borrowing power, if applicable to the account.
 
     To participate in the Plan, an investor must be an RMA accountholder, must
have made an initial purchase of the shares of each PW Fund selected for
investment under the Plan (meeting applicable minimum investment requirements)
and must complete and submit the RMA Resource Accumulation Plan Client Agreement
and Instruction Form available from PaineWebber. The investor must have received
a current prospectus for each PW Fund selected prior to enrolling in the Plan.
Information about mutual fund positions and outstanding instructions under the
Plan are noted on the RMA accountholder's account statement. Instructions under
the Plan may be changed at anytime, but may take up to two weeks to become
effective.
 
     The terms of the Plan or an RMA accountholder's participation in the Plan,
may be modified or terminated at any time. It is anticipated that, in the
future, shares of other PW Funds and/or mutual funds other than the PW Funds may
be offered through the Plan.
 
     PERIODIC INVESTING AND DOLLAR COST AVERAGING. Periodic investing in the PW
Funds or other mutual funds, whether through the Plan or otherwise, helps
investors establish and maintain a disciplined approach to accumulating assets
over time, de-emphasizing the importance of timing the market's highs and lows.
Periodic investing also permits an investor to take advantage of 'dollar cost
averaging.' By investing a fixed amount in mutual fund shares at established
intervals, an investor purchases more shares when the price is lower and fewer
shares when the price is higher, thereby increasing his or her earning
potential. Of course, dollar cost averaging does not guarantee a profit or
protect against a loss in a declining market, and an investor should consider
his or her financial ability to continue investing through periods of low share
prices. However, over time, dollar cost averaging generally results in a lower
average original investment cost than if an investor invested a larger dollar
amount in a mutual fund at one time.
 
     PAINEWEBBER'S RESOURCE MANAGEMENT ACCOUNT. In order to enroll in the Plan,
an investor must have opened an RMA account with PaineWebber or one of its
correspondent firms. The RMA account is PaineWebber's comprehensive asset
management account and offers investors a number of features, including the
following:
 
                                       46
<PAGE>
     o monthly Premier account statements that itemize all account activity,

       including investment transactions, checking activity and Gold
       MasterCard(Registered) transactions during the period, and provide
       unrealized and realized gain and loss estimates for most securities held
       in the account;
 
     o comprehensive preliminary 9-month and year-end summary statements that
       provide information on account activity for use in tax planning and tax
       return preparation;
 
     o automatic 'sweep' of uninvested cash into the RMA accountholder's choice
       of one of the seven RMA money market funds-RMA Money Market Portfolio,
       RMA U.S. Government Portfolio, RMA Tax-Free Fund, RMA California
       Municipal Money Fund, RMA Connecticut Municipal Money Fund, RMA New
       Jersey Municipal Money Fund and RMA New York Municipal Money Fund. Each
       money market fund attempts to maintain a stable price per share of $1.00,
       although there can be no assurance that it will be able to do so.
       Investments in the money market funds are not insured or guaranteed by
       the U.S. government;
 
     o check writing, with no per-check usage charge, no minimum amount on
       checks and no maximum number of checks that can be written. RMA
       accountholders can code their checks to classify expenditures. All
       canceled checks are returned each month;
 
     o Gold MasterCard, with or without a line of credit, which provides RMA
       accountholders with direct access to their accounts and can be used with
       automatic teller machines worldwide. Purchases on the Gold MasterCard are
       debited to the RMA account once monthly, permitting accountholders to
       remain invested for a longer period of time;
 
     o 24-hour access to account information through toll-free numbers, and more
       detailed personal assistance during business hours from the RMA Service
       Center;
 
     o expanded account protection to $25 million in the event of the
       liquidation of PaineWebber. This protection does not apply to shares of
       the RMA money market funds or the PW Funds because those shares are held
       at the transfer agent and not through PaineWebber; and
 
     o automatic direct deposit of checks into your RMA account and automatic
       withdrawals from the account.
 
     The annual account fee for an RMA account is $85, which includes the Gold
MasterCard, with an additional fee of $40 if the investor selects an optional
line of credit with the Gold MasterCard.
 
                          CONVERSION OF CLASS B SHARES
 
     Class B shares of each Fund will automatically convert to Class A shares,
based on the relative net asset values of each of the Classes, as of the close
of business on the first Business Day (as defined under 'Valuation of Shares')
of the month in which the sixth anniversary of the initial issuance of such
Class B shares of the Fund occurs. For the purpose of calculating the holding
period required for conversion of Class B shares, the date of initial issuance

shall mean (1) the date on which such Class B shares were issued, or (2) for
Class B shares obtained through an exchange, or a series of exchanges, the date
on which the original Class B shares were issued. If a shareholder acquired
Class B shares of a Fund through an exchange of Class B shares of a CDSC Fund
that were acquired prior to July 1, 1991, the shareholder's holding period for
purposes of conversion is determined based on the date the CDSC Fund shares were
initially issued. For purposes of conversion to Class A, Class B shares
purchased through the reinvestment of dividends and other distributions paid in
respect of Class B shares will be held in a separate sub-account. Each time any
Class B shares in the shareholder's regular account (other than those in the
sub-account) convert to Class A, a pro rata portion of
 
                                       47
<PAGE>
the Class B shares in the sub-account will also convert to Class A. The portion
will be determined by the ratio that the shareholder's Class B shares converting
to Class A bears to the shareholder's total Class B shares not acquired through
dividends and other distributions.
 
     Under normal circumstances, the net asset values per share of the two
Classes of each Fund will be the same. However, if a Fund's accrued expenses on
any Business Day were to exceed the Fund's accrued income for that Business Day,
the net asset value per share of the Class B shares could be lower than that of
the Class A shares because of the higher ongoing expenses borne by the Class B
shares. If such a divergence existed on a conversion date, a shareholder would
receive fewer Class A shares than the number of Class B shares converted,
although the dollar value would be the same. Mitchell Hutchins considers the
possibility of such an occurrence to be remote.
 
     The availability of the conversion feature is subject to (1) the continuing
applicability of a ruling of the Internal Revenue Service that the dividends and
other distributions paid on Class A and Class B shares will not result in
'preferential dividends' under the Internal Revenue Code and (2) the continuing
availability of an opinion of counsel to the effect that the conversion of
shares does not constitute a taxable event. If the conversion feature ceased to
be available, the Class B shares of each Fund would not be converted and would
continue to be subject to the higher ongoing expenses of the Class B shares
beyond six years from the date of purchase. Mitchell Hutchins has no reason to
believe that these conditions for the availability of the conversion feature
will not continue to be met.
 
                              VALUATION OF SHARES
 
     Each Fund determines the net asset value per share separately for each
Class of shares as of the close of regular trading (currently 4:00 p.m., Eastern
time) on the NYSE on each Business Day, which is defined as each Monday through
Friday when the NYSE is open. Currently, the NYSE is closed on the observance of
the following holidays: New Year's Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.
 
     Where market quotations are readily available, portfolio securities are
valued based upon market quotations, provided such quotations adequately
reflect, in the judgment of Mitchell Hutchins, the fair value of the security.
Where such market quotations are not readily available, securities are valued

based upon appraisals received from a pricing service using a computerized
matrix system or based upon appraisals derived from information concerning the
security or similar securities received from recognized dealers in those
securities. The amortized cost method of valuation generally is used with
respect to debt obligations with 60 days or less remaining to maturity unless
the Trust's board of trustees determines that this does not represent fair
value. All other assets will be valued at fair value as determined in good faith
by or under the direction of each Trust's boards of trustees.

                            PERFORMANCE INFORMATION
 
     Each Fund's performance data quoted in advertising and other promotional
materials ('Performance Advertisements') represent past performance and are not
intended to indicate future performance. The investment return and principal
value of an investment will fluctuate so that an investor's shares, when
redeemed, may be worth more or less than their original cost.
 
     TOTAL RETURN CALCULATIONS.  Average annual total return quotes
('Standardized Return') used in a Fund's Performance Advertisements are
calculated according to the following formula:
 
<TABLE>
<S>           <C>   <C>
  P(1 + T)n    =    ERV
 
where:    P    =    a hypothetical initial payment of $1,000 to purchase shares
                    of a specified Class
 
          T    =    average annual total return of shares of that Class
 
          n    =    number of years
 
        ERV    =    ending redeemable value of a hypothetical $1,000 payment
                    made at the beginning of that period.
</TABLE>
 
     Under the foregoing formula, the time periods used in Performance
Advertisements will be based on rolling calendar quarters, updated to the last
day of the most recent quarter prior to submission of the advertisement for
publication. Total return, or 'T' in the formula above, is computed by finding
the average annual change in the value of an initial $1,000 investment over the
period. In calculating the ending redeemable value for Class A shares, the
maximum 4% initial sales charge is deducted from the initial $1,000 payment and,
for Class B and Class C shares, the applicable contingent deferred sales charge
imposed on a redemption of Class B or Class C shares held for the period is
deducted. All dividends and other distributions are assumed to have been
reinvested at net asset value. Each Fund also may refer in Performance
Advertisements to total return performance data that are not calculated
according to the formula set forth above ('Non-Standardized Return'). A Fund
calculates Non-Standardized Return for specified periods of time by assuming an
investment of $1,000 in Fund shares and assuming the reinvestment of all
dividends and other distributions. The rate of return is determined by
subtracting the initial value of the investment from the ending value and by
dividing the remainder by the initial value. Neither initial nor contingent
deferred sales charges are taken into account in calculating Non-Standardized
Return; the inclusion of those charges would reduce the return.
 
     Both Standardized Return and Non-Standardized Return for Class B shares for
periods of over six years will reflect conversion of the Class B shares to Class
A shares at the end of the sixth year.
 
     The following table shows performance information for the Class A, Class B

and Class C (formerly Class D) shares of the Funds for the periods indicated.
All returns for periods of more than one year are expressed as an average annual
return.

** The inception dates for the Class A shares of the Funds are as follows:
   California Tax-Free Income Fund--September 16, 1985; National Tax-Free
   Income Fund--December 3, 1984; Municipal High Income Fund--June 23, 1987;
   and New York Tax-Free Income Fund--September 23, 1988. The inception dates
   for the Class B shares and Class C shares (formerly Class D shares) of each
   Fund are July 1, 1991 and July 2, 1992, respectively.
 
     YIELD.  Yields used in each Fund's Performance Advertisements are
calculated by dividing the Fund's interest income attributable to a Class of
shares for a 30-day period ('Period'), net of expenses attributable to such
Class, by the average number of shares of such Class entitled to receive
dividends during the Period and expressing the result as an annualized
percentage (assuming semi-annual compounding) of the maximum offering price per
share (in the case of Class A shares) or the net asset value per share (in the
case of Class B and Class C shares (formerly Class D shares)) at the end of the
Period. Yield quotations are calculated according to the following formula:
 

                    (  a-b     )6
     YIELD   =   2 [( ----- + 1)  -1]
                    (  cd      )
 
     where: a    =    interest earned during the Period attributable to a 
                      Class of shares
            b    =    expenses accrued for the Period attributable to a 
                      Class of shares (net of reimbursements)
            c    =    the average daily number of shares of the Class 
                      outstanding during the Period that were 
                      entitled to receive dividends
            d    =    the maximum offering price per share (in the case 
                      of Class A shares) or the net asset value per share 
                      (in the case of Class B and Class C shares) on 
                      the last day of the Period.
 
     Except as noted below, in determining net investment income earned during
the Period (variable 'a' in the above formula), a Fund calculates interest
earned on each debt obligation held by it during the Period by (1) computing the
obligation's yield to maturity, based on the market value of the obligation
(including actual accrued interest) on the last business day of the Period or,
if the obligation was purchased during the Period, the purchase price plus
accrued interest and (2) dividing the yield to maturity by 360 and multiplying
the resulting quotient by the market value of the obligation (including actual
accrued interest) to determine the interest income on the obligation for each
day of the period that the obligation is in the portfolio. Once interest earned
is calculated in this fashion for each debt obligation held by a Fund, interest

earned during the
 
                                       50
<PAGE>
Period is then determined by totalling the interest earned on all debt
obligations. For purposes of these calculations, the maturity of an obligation
with one or more call provisions is assumed to be the next date on which the
obligation reasonably can be expected to be called or, if none, the maturity
date. With respect to Class A shares, in calculating the maximum offering price
per share at the end of the Period (variable 'd' in the above formula), a Fund's
current maximum 4% initial sales charge on Class A shares is included. The Funds
had the following yields for the 30-day period ended February 28, 1995:

     Tax-exempt yield is calculated according to the same formula except that
variable 'a' equals interest exempt from federal income tax earned during the
Period. This tax-exempt yield is then translated into tax-equivalent yield
according to the following formula:
 
TAX EQUIVALENT YIELD = (  E    )
                       ( ----- ) + t
                       (  1 - p)
 
       E =    tax-exempt yield of a Class of shares
       p =    stated income tax rate
       t  =   taxable yield of a Class of shares
 
     The tax-equivalent yield of California Tax-Free Income Fund assumes a
46.24% combined effective California and federal tax rate. The tax-equivalent
yield of New York Tax-Free Income Fund assumes a 46.88% effective New York
State, New York City and federal tax rate. The tax-equivalent yield of each of
National Tax-Free Income Fund and Municipal High Income Fund assumes a 39.6%
effective federal tax rate.
 
     The Funds had the following tax-equivalent yields for the 30-day period
ended February 28, 1995:

such materials to mutual fund performance rankings and other data, such as

LETTERS. Comparisons in performance advertisements may be in graphic form.
 
     Each Fund may include discussions or illustrations of the effects of
compounding in Performance Advertisements. 'Compounding' refers to the fact
that, if dividends or other distributions on an investment in a Fund are
reinvested by being paid in additional Fund shares, any future income or capital
appreciation of a Fund would increase the value, not only of the original Fund
investment, but also of the additional Fund shares received through
reinvestment. As a result, the value of the Fund investment would increase more
quickly than if dividends or other distributions had been paid in cash.
 
     Each Fund may also compare its performance with the performance of bank
certificates of deposit (CDs) as measured by the CDA Investment Technologies,
Inc. Certificate of Deposit Index and the Bank Rate Monitor National Index and
the averages of yields of CDs of major banks published by Banxquote(Registered)
Money Markets. In comparing the Fund's performance to CD performance, investors
should keep in mind that bank CDs are insured in whole or in part by an agency
of the U.S. government and offer fixed principal and fixed or variable rates of
interest, and that bank CD yields may vary depending on the financial
institution offering the CD and prevailing interest rates. Fund shares are not
insured or guaranteed by the U.S. government and returns and net asset value

will fluctuate. The securities held by the Fund generally have longer maturities
than most CDs and may reflect interest rate fluctuations for longer term
securities. An investment in a Fund involves greater risks than an investment in
either a money market fund or a CD.

                                     TAXES
 
     FEDERAL TAXES.  In order 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 the
sum of its net interest income excludable from gross income under section 103(a)
of the Internal Revenue Code plus its investment company taxable income
(consisting generally of taxable net investment income plus net short-term
capital gain) and must meet several additional requirements. For 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 and gains from the sale or other disposition of securities,
or other income (including gains from options or futures) derived with respect
to its business of investing in securities ('Income Requirement'); (2) the Fund
must derive less than 30% of its gross income each taxable year from the sale or
other disposition of securities, options or futures held for less than three
months ('Short-Short Limitation'); (3) at the close of each quarter of the
Fund's taxable year, at least 50% of the value of its total assets must be
represented by cash and cash items, U.S. government securities, securities of
other RICs and other securities that are limited, in respect of any one issuer,
to an amount that does not exceed 5% of the value of the Fund's total assets;
and (4) at the close of each quarter of the Fund's taxable year, not more than
25% of the value of its total assets may be invested in securities (other than
U.S. government securities or the securities of other RICs) of any one issuer.
 
     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 Fund shares because, for users of certain of
these facilities, the interest on those bonds is not exempt from federal income
tax. For these purposes, 'substantial user' is defined to include a 'non-exempt
person' who regularly uses in a 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 Fund) plus 50% of their benefits
exceeds certain base amounts. Exempt-interest dividends from a Fund still are
tax-exempt to the extent described in the Prospectus; they are only included in
the calculation of whether a recipient's income exceeds the established amounts.
 
     If Fund shares are sold at a loss after being held for six months or less,
the loss will be disallowed to the extent of any exempt-interest dividends
received on those shares and any loss not disallowed will be treated as
long-term, instead of short-term, capital loss to the extent of any capital gain
distributions received thereon. Investors also should be aware that if shares
are purchased shortly before the record date for a capital gain distribution,

the shareholder will pay full price for the shares and receive some portion of
the price back as a taxable distribution.
 
     Special tax rules apply when a shareholder (1) disposes of Class A shares
through a redemption or exchange within 90 days of purchase and subsequently
acquires Class A shares of a PaineWebber or MH/KP fund without paying a sales
charge due to the 365-day reinstatement privilege or exchange privilege. See
'Reduced Sales Charges--Reinstatement Privilege--Class A shares' above and
'Exchanges' in the Prospectus. In these cases, any gain on the disposition of
the Class A shares would be increased, or loss decreased, by the amount of the
sales charge paid when the shares were acquired, and that amount will increase
the basis of the PaineWebber fund shares subsequently acquired. In addition, if
shares of a Fund are purchased within 30 days before or after redeeming that
Fund's shares (regardless of Class) at a loss, that loss will not be deductible
to the extent the redemption proceeds are reinvested and will increase the basis
of the newly purchased shares.
 
                                       53

     Although no Fund currently expects to invest in instruments that generate
taxable interest income, if a Fund does so, 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 the Fund's shareholders as ordinary income to the extent of
the Fund's earnings and profits, and only the remaining portion will qualify as
an 'exempt-interest dividend' (as described in the Prospectus). The respective
portions will be determined by the 'actual earned' method, under which the
portion of any dividend that qualifies as exempt-interest may vary, depending on
the relative proportions of tax-exempt and taxable interest earned during the
dividend period. Moreover, if a Fund realizes capital gain as a result of market
transactions, any distributions of the gain will be taxable to its shareholders.
Each Fund is required to withhold 31% of all taxable dividends, capital gain
distributions and redemption proceeds payable to any individuals and certain
other noncorporate shareholders who do not provide the Fund with a correct
taxpayer identification number. Each Fund also is required to withhold 31% of
all taxable dividends and capital gain distributions payable to those
shareholders who otherwise are subject to backup withholding.
 
     Dividends and other distributions declared by a Fund in October, November
or December of any year and payable to shareholders of record on a date in any
of those months will be deemed to have been paid by the Fund and received by the
shareholders on December 31 of that year if the distributions are paid by the
Fund during the following January. Each Fund invests exclusively in debt
securities and receives no dividend income; accordingly, no portion of the
dividends or other distributions paid by any Fund is eligible for the
dividends-received deduction allowed to corporations.
 
     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 of its
ordinary (taxable) income for the calendar year and capital gain net income for
the one-year period ending on October 31 of that year, plus certain other
amounts.
 
     The use of hedging and option income strategies, such as writing (selling)

and purchasing options and futures, involves complex rules that will determine
for income tax purposes the character and timing of recognition of the gains and
losses a Fund realizes in connection therewith. Income from transactions in
options and futures derived by a Fund with respect to its business of investing
in securities will qualify as permissible income under the Income Requirement.
However, income from the disposition of options and futures will be subject to
the Short-Short Limitation if they are held for less than three months.
 
     If a Fund satisfies certain requirements, any increase in value of a
position that is part of a 'designated hedge' will be offset by any decrease in
value (whether realized or not) of the offsetting hedging position during the
period of the hedge for purposes of determining whether the Fund satisfies the
Short-Short Limitation. Thus, only the net gain (if any) from the designated
hedge will be included in gross income for purposes of that limitation. Each
Fund will consider whether it should seek to qualify for this treatment for its
hedging transactions. To the extent a Fund does not qualify for this treatment,
it may be forced to defer the closing out of certain options and futures beyond
the time when it otherwise would be advantageous to do so, in order for the Fund
to continue to qualify as a RIC.
 
     Each 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 purchased by a Fund after
April 30, 1993 (other than a bond with a fixed
 
                                       54
<PAGE>
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 Fund may elect to include market discount in its gross income
currently, for each taxable year to which it is attributable.
 
     CALIFORNIA TAXES.  Individual shareholders of California Tax-Free Income
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 obligations
of U.S. possessions or territories) ('exempt-interest dividends'), provided that
the Fund qualifies as a RIC under the Internal Revenue Code and 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 under the laws or Constitution of
California or the laws of the United States. Distributions from the Fund which
are attributable to sources other than those described in the preceding sentence
will generally be taxable to such shareholders as ordinary income. However,

distributions by California Tax-Free Income 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. Moreover, under
California legislation incorporating certain portions of the provisions of the
Internal Revenue Code applicable to RICs, amounts treated as capital gain
distributions for federal income tax purposes generally will be treated as
long-term capital gains for California personal income tax purposes. In
addition, distributions to shareholders other than exempt-interest dividends are
includable in income subject to the California alternative minimum tax.
 
     Distributions of investment income and long-term and short-term capital
gains will not be excluded from taxable income in determining the California
corporate franchise tax for corporate shareholders. In addition, such
distributions may be includable in income subject to the California alternative
minimum tax.
 
     Interest on indebtedness incurred by shareholders to purchase or carry
shares of California Tax-Free Income Fund will not be deductible for California
personal income tax purposes.
 
     Shares of California Tax-Free Income Fund will not be subject to the
California property tax.
 
     NEW YORK TAXES.  Individual shareholders of New York Tax-Free Income Fund
will not be required to include in their gross income for New York State
purposes any portion of distributions received from the 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 the 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 the Fund qualifies as a RIC under
the Internal Revenue Code and satisfies the requirements 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 the 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. However, distributions by the Fund, if any,
that are derived from interest earned on obligations of the U.S. government may
also be designated by the Fund and treated by its shareholders as exempt from
personal income taxation for New York State and City purposes, provided that at
least 50% of the value of its total assets at the close of each quarter of its
taxable year is invested in such federal obligations. Distributions to
individual
 
                                       55
<PAGE>
shareholders by the Fund which represent 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.
 
     Shareholders of New York Tax-Free Income Fund that are subject to the New
York State corporation franchise tax or the City general corporation tax will be

required to include exempt-interest dividends paid by the Fund in their 'entire
net income' for purposes of such taxes and will be required to include their
shares of the Fund in their investment capital for purposes of such taxes.
 
     Shareholders of New York Tax-Free Income Fund will not be subject to the
unincorporated business taxation imposed by the City solely by reason of their
ownership of shares in the Fund. If a shareholder is subject to the
unincorporated business tax, income and gains distributed by the Fund will be
subject to such tax except 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 the City).
 
     Shares of New York Tax-Free Income Fund will not be subject to property
taxes imposed by New York State or the City.
 
     Interest on indebtedness incurred by shareholders to purchase or carry
shares of the New York Tax-Free Income Fund generally will not be deductible for
New York State personal income tax purposes.
 
     Interest income of the Fund which is distributed to the shareholders will
generally not be taxable to the Fund for purposes of the New York State
corporation franchise tax or the New York City general corporation tax.
 
     The foregoing is a general summary of certain provisions of federal,
California and New York State and City tax laws currently in effect as they
directly govern the taxation of shareholders of the Funds. 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
tax matters.

   Assumes that all income is ordinary income.
 
2. The income ranges shown for 1996 reflect federal and California income
   brackets for 1995. Inflation adjusted income brackets for 1996 are not yet
   available.
 
3. The rates shown reflect federal and California rates for 1996 in effect as of
   the date hereof. Those rates are still subject to change with retroactive
   effect for 1996.
 
4. Excludes the impact of the phase out of personal exemptions, limitations on

   increase a taxpayer's marginal tax rate as well as the effect of certain
   levels of income (including tax exempt income) on the taxability of social
   security payments.

* See note following Table III.
 
     TAX-FREE INCOME VS. TAXABLE INCOME--NEW YORK TAX-FREE INCOME FUND.  Table
III below illustrates approximate equivalent taxable and tax-free yields at the
1995 federal individual, and New York State and New York City personal, income
tax rates. For example, a New York City couple with taxable income of $90,000 in
1995, whose investments earn a 4% tax-free yield, would have to earn a 6.59%
taxable yield to receive the same benefit. A couple who lives in New York State
outside of New York City with taxable income of $90,000 in 1995 would have to
earn a 6.27% taxable yield to realize a 4% tax-free yield.
 
     Single taxpayers may also take advantage of high tax-free income. For
example, a single individual with taxable income of $55,000 in 1995 who lives in
New York City and whose investments earn a 4% tax-free yield, would have to earn
a 6.59% taxable yield to receive the same benefit. A single individual with
taxable income of $55,000 in 1995, who lives in New York State outside of New
York City would have to earn a 6.27% taxable yield to realize a 4% tax-free
yield.

*Single rate assumes no dependents; joint rate assumes two dependents. The
 yields listed are for illustration only and are not necessarily representative
 of a Fund's yield. Each Fund invests primarily in obligations the interest on
 which is exempt from federal income tax and, in the case of California Tax-Free
 Income Fund, from California personal income tax and, in the case of New York
 Tax-Free Income Fund, from New York State and New York City personal income
 taxes; however, some of a Fund's investments may generate taxable income.
 Effective tax rates shown are those in effect on the date of this Statement of
 Additional Information; such rates might change after that date. The effective
 rates reflect the highest tax bracket within each range of income listed.
 However, a California or New York taxpayer within the lowest income ranges
 shown may fall within a lower effective tax bracket. The figures set forth
 above do not reflect the federal alternative minimum tax, limitations on
 federal or state itemized deductions and personal exemptions or any state or
 local taxes payable on Fund distributions (other than California, New York
 State and New York City personal income taxes in the case of Tables II and
 III).

                               OTHER INFORMATION
 
     The names of the Trusts are PaineWebber Mutual Fund Trust and PaineWebber
Municipal Series. Prior to April 6, 1992, the name of PaineWebber Mutual Fund
Trust was PaineWebber California Tax-Free Income Fund and its sole operating
series was designated as 'Initial Series.' Prior to July 1, 1991, the name of
this Trust was PaineWebber California Tax-Exempt Income Fund. Prior to June 30,
1992, National Tax-Free Income Fund was a series of a different Massachusetts
business trust, PaineWebber Managed Municipal Trust. Prior to July 1, 1991, the
name of Municipal High Income Fund was 'PaineWebber Classic High Yield Municipal
Fund' and prior to July 1, 1989, its name was 'PaineWebber High Yield Municipal
Bond Fund.' Prior to July 1, 1991, the name of New York Tax-Free Income Fund was
'PaineWebber Classic New York Tax-Free Fund.' Prior to November 10, 1995, the
Funds' Class C shares were known as 'Class D' shares.
 
     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 the Trust or a
Fund. However, the Declaration of Trust disclaims shareholder liability for the
obligations of the Trust or a Fund and requires that notice of such disclaimer
be given in each note, bond, contract, instrument, certificate or undertaking
made or issued by the Trust's trustees or by any officers or officer by or on
behalf of a Fund, the trustees or any of them in connection with the Fund. The
Declaration of Trust provides for indemnification from a Fund's property for all
losses and expenses of any Fund shareholder held personally liable for the
obligations of the Fund. Thus, the risk of a shareholder's incurring financial

loss on account of shareholder liability is limited to circumstances in which
the Fund itself would be unable to meet its obligations, a possibility that
Mitchell Hutchins believes is remote and not material. Upon payment of any
liability incurred by a shareholder solely by reason of being or having been a
shareholder, the shareholder paying such liability will be entitled to
reimbursement from the general assets of a 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.
 
     CLASS-SPECIFIC EXPENSES.  Each Fund may determine to allocate certain of
its expenses (in addition to distribution fees) to the specific Classes of the
Fund's shares to which those expenses are attributable. For example, Class B
shares bear higher transfer agency fees per shareholder account than those borne
by Class A or Class C shares. The higher fee is imposed due to the higher costs
incurred by the transfer agent in tracking shares subject to a contingent
deferred sales charge because, upon redemption, the duration of the
shareholder's investment must be determined in order to determine the applicable
charge. Moreover, the tracking and calculations required by the automatic
conversion feature of the Class B shares will cause the transfer agent to incur
additional costs. Although the transfer agency fee will differ on a per account
basis as stated above, the specific extent to which the transfer agency fees
will differ between the Classes as a percentage of net assets is not certain,
because the fee as a percentage of net assets will be affected by the number of
shareholder accounts in each Class and the relative amounts of net assets in
each Class.

THE FUNDS MAY USE THE FOLLOWING HEDGING AND OPTION INCOME INSTRUMENTS:
 
     OPTIONS ON DEBT SECURITIES--A call option is a short-term contract pursuant
to which the purchaser of the option, in return for a premium, has the right to
buy the security underlying the option at a specified price at any time during
the term of the option. The writer of the call option, who receives the premium,
has the obligation, upon exercise of the option during the option term, to
deliver the underlying security against payment of the exercise price. A put
option is a similar contract which gives its purchaser, in return for a premium,
the right to sell the underlying security at a specified price during the option
term. The writer of the put option, who receives the premium, has the
obligation, upon exercise during the option term, to buy the underlying security
at the exercise price. Options on debt securities are traded primarily in the
OTC market rather than on any of the several options exchanges. At present, only
options on U.S. Treasury securities are listed for trading on any recognized
exchange.
 
     OPTIONS ON INDEXES OF DEBT SECURITIES--An index assigns relative values to
the securities included in the index and fluctuates with changes in the market
values of such securities. Index options operate in the same way as more
traditional options except that exercises of index options are effected with
cash payments and do not involve delivery of securities. Thus, upon exercise of
an index option, the purchaser will realize and the writer will pay, an amount
based on the difference between the exercise price and the closing price of the
index. Currently, options on indexes of debt securities do not exist.
 
     MUNICIPAL BOND INDEX FUTURES CONTRACTS--A municipal bond index futures
contract is a bilateral agreement pursuant to which one party agrees to accept
and the other party agrees to make delivery of an amount of cash equal to a
specified dollar amount times the difference between the index value at the
close of trading of the contract and the price at which the futures contract is
originally struck. No physical delivery of the bonds comprising the index is
made; generally contracts are closed out prior to the expiration date of the
contract.
 
     MUNICIPAL DEBT FUTURES CONTRACTS--A municipal debt futures contract is a
bilateral agreement pursuant to which one party agrees to accept and the other
party agrees to make delivery of the specific type of municipal debt security
called for in the contract at a specified future time and at a specified price.
Currently there is no public market for municipal debt futures contracts.
 
     OPTIONS ON FUTURES CONTRACTS--Options on futures contracts are similar to
options on securities except that an option on a futures contract gives the
purchaser the right, in return for the premium, to assume a position in a
futures contract (a long position if the option is a call and a short position
if the option is a put), rather than to purchase or sell a security, at a
specified price at any time during the option term. Upon exercise of the option,
the delivery of the futures position to the holder of the option will be
accompanied by delivery of the accumulated balance, which represents the amount
by which the market price of the futures contract exceeds, in the case of a
call, or is less than, in the case of a put, the exercise price of the option on

the future. The writer of an option, upon exercise, will assume a short position
in the case of a call, and a long position in the case of a put.
