                   INVESTMENT GRADE MUNICIPAL INCOME FUND INC.
                      __ AUCTION PREFERRED SHARES SERIES C
                    LIQUIDATION PREFERENCE $50,000 PER SHARE

Investment Grade Municipal Income Fund Inc. (the "Fund") is offering __ Auction
Preferred Shares, Series C ("APS Series C"). APS Series C have a liquidation
preference of $50,000 per share, plus any accumulated, unpaid dividends. APS
Series C also have priority over the Fund's common stock as to distribution of
assets as described in this prospectus. It is a condition of closing this
offering that the APS Series C be offered with a rating of "Aaa" from Moody's
and "AAA" from S&P. The Fund currently has 800 shares of each of APS Series A
and APS Series B outstanding. APS Series A, B and C are collectively referred to
herein as "APS."

The Fund is a diversified, closed-end management investment company. The Fund's
investment objective is to achieve a high level of current income that is exempt
from federal income tax, consistent with the preservation of capital. To achieve
this objective, the Fund normally invests substantially all of its assets in a
diversified portfolio of Municipal Obligations. Under normal circumstances, the
Fund invests at least 80% of its net assets in investment grade Municipal
Obligations, the income from which is exempt from regular federal income tax.
Municipal Obligations rated investment grade are those that, at the time of
investment, are rated within the four highest grades by Moody's Investors
Service, Inc. (Baa or higher) or Standard & Poor's, a division of The
McGraw-Hill Companies, Inc., (BBB or higher) or have an equivalent rating from
another nationally recognized statistical rating organization ("NRSRO" or
"rating agency"). The Fund may invest up to 20% of its net assets in Municipal
Obligations that are unrated but that, at the time of investment, have been
determined by the Fund's investment advisor to be of comparable quality to
those that are rated investment grade. There is no assurance that the Fund
will achieve its investment objective. All or a portion of the Fund's
dividends may be attributable to interest income that is an item of tax
preference for purposes of the federal alternative minimum tax.

UBS Global Asset Management (US) Inc. ("UBS Global AM") serves as investment
advisor and administrator to the Fund. The address of the Fund is 51 West 52nd
Street, New York, New York 10019-6114, and its telephone number is 212-882 5000.

RISKS. Investing in APS involves certain risks. See "Investment Objectives and
Policies" and "Investment Risks." The minimum purchase amount of APS Series C is
$50,000.

As with all investment companies, neither the Securities and Exchange Commission
("SEC") nor any state securities commission has approved or disapproved the APS
or determined whether this prospectus is complete or accurate. To state
otherwise is a crime.

with respect to each series of the APS that is taxable for federal income tax
purposes in advance of the related auction, as described in more detail below.
The amount of taxable income allocable to the APS will depend on the amount of

commitment to purchase or sell APS based upon the results of an auction, (ii)

conditions may designate any dividend period of any APS series as a special
dividend period, which shall be such number of consecutive days, whole months or
whole years as the Fund's board of directors ("Board") shall specify, subject to
certain conditions. The shares of each series of APS are redeemable by the Fund
as described herein. See "Description of APS--Redemption."

                              trades on the New York Stock Exchange under the
                              symbol "PPM." See "Description of Common Stock."
                              As of September 19, 2003, the Fund had outstanding
                              10,356,667 shares of common stock, 800 shares of
                              Auction Preferred Shares Series A, and 800 shares
                              of Auction Preferred Shares Series B. As of
                              September 19, 2003, the Fund's total assets were
                              $246,893,611.

Investment Objective          The Fund's investment objective is to achieve a
and Policies                  high level of current income that is exempt from
                              federal income tax, consistent with the
                              preservation of capital. There is no assurance
                              that the Fund will achieve its investment
                              objective.

                              To achieve its investment objective, the Fund
                              normally invests substantially all of its assets
                              in a diversified portfolio of Municipal
                              Obligations. Under normal circumstances, the Fund
                              invests at least 80% of its net assets in
                              investment grade Municipal Obligations, the income
                              from which is exempt from regular federal income
                              tax. Municipal Obligations rated investment grade
                              are those that, at the time of investment, are
                              rated within the four highest grades by Moody's
                              Investors Service, Inc. ("Moody's") (Baa or
                              higher) or Standard & Poor's, a division of The
                              McGraw Hill Companies, Inc. ("S&P"), (BBB or
                              higher) or have an equivalent rating from another
                              nationally recognized statistical rating
                              organization. The Fund may invest up to 20% of its
                              net assets in Municipal Obligations that are
                              unrated but that, at the time of investment, have
                              been determined by UBS Global AM to be of
                              comparable quality to those that are rated
                              investment grade.

                              At least 80% of the Fund's net assets normally are
                              invested in Municipal Obligations the interest on
                              which is not an item of tax preference for
                              purposes of the federal alternative minimum tax
                              ("AMT") ("Tax Preference Item"). Under normal
                              circumstances, the Fund may invest in high
                              quality, short-term, tax-exempt investments, and
                              with respect to up to 20% of its net assets,
                              taxable investments, in order to invest cash
                              reserves, or it may make such investments on a
                              temporary basis during defensive periods or when,
                              in the opinion of UBS Global AM, no suitable
                              longer-term Municipal Obligations are available.
                              The Fund may engage in when-issued and delayed
                              delivery transactions, enter into stand-by
                              commitments, purchase illiquid securities, invest
                              in repurchase agreements, lend portfolio
                              securities and enter into certain hedging and
                              related income strategies. The Fund may enter into
                              options and futures that, at a maximum,
                              approximate (but do not exceed) the full value of
                              its portfolio assets. Certain of these investment
                              practices entail additional risks and may give
                              rise to taxable income; however, they may also be
                              used to manage risks. The Fund may use options
                              (both exchange-traded and OTC) to attempt to
                              enhance income (which would be taxable income) and
                              also may attempt to "hedge" or manage the overall
                              risk of its investments by using options, futures
                              contracts and interest rate protection
                              transactions. The Fund may use derivatives as a
                              substitute for taking a position in an underlying
                              security or other asset and/or as part of a
                              strategy designed to reduce exposure to other
                              risks, such as interest rate risk. The Fund also
                              may use derivatives to add leverage to the
                              portfolio and/or to hedge against increases in the
                              Fund's costs associated with the dividend payments
                              on the preferred stock, including the APS. See
                              "Investment Objective and Policies," "Investment
                              Risks," "Taxation" and Appendix A.

Investment Advisor            UBS Global AM, an indirect, wholly owned
and Administrator             subsidiary of UBS AG, is the Fund's investment
                              advisor and administrator. UBS Global AM provides
                              investment advisory and portfolio management
                              services to investment companies, pension funds

                              and other institutional, corporate and individual
                              clients. As investment advisor and administrator,
                              UBS Global AM is entitled to receive from the Fund
                              a fee, computed weekly and paid monthly, in an
                              amount equal to an annual rate of 0.90% of the
                              Fund's average weekly net assets. UBS Global AM
                              has agreed to waive a portion of its fee in the
                              amount of 0.20% of average weekly net assets,
                              effectively reducing the annual fee paid to UBS
                              Global AM by the Fund to 0.70% of average weekly
                              net assets. This waiver will continue indefinitely
                              unless the Fund's Board of Directors agrees to any
                              change. See "Management of the Fund."

The Offering                  The Fund is offering its preferred stock,
                              designated as Auction Preferred Shares ("APS"),
                              Series C, at a purchase price of $50,000 per
                              share. APS Series C shares are being offered by
                              UBS Securities LLC.

Auction Preferred             The Fund has outstanding 800 shares of APS Series
Shares                        A and 800 of APS Series B, having Shares an
                              aggregate liquidation value of $80,000,000. Shares
                              of APS Series C are very similar to APS Series A
                              and APS Series B. The issuance of APS Series C
                              will increase the total assets of the Fund. The
                              APS pay dividends at rates that are adjusted over
                              relatively short periods of time and that reflect
                              prevailing short-term, tax-exempt interest rates.
                              The proceeds of APS offerings are invested in
                              longer-term Municipal Obligations, which typically
                              bear interest at rates that are higher than
                              short-term, tax-exempt interest rates. The APS
                              offered hereby are expected to receive ratings of
                              Aaa from Moody's and AAA from S&P. See
                              "Description of APS."

Risk Factors                  Risk is inherent in all investing. Therefore,
Summary                       before investing in the APS, you should consider
                              certain risks carefully. The primary risks of
                              investing in the APS are:
                              -    if an auction fails, you may not be able to
                                   sell some or all of your shares;
                              -    because of the nature of the market for APS,
                                   you may receive less than the price you paid
                                   for your shares if you sell them outside of
                                   the auction, especially when market interest
                                   rates are rising;
                              -    a rating agency could suspend, withdraw or
                                   downgrade the rating assigned to the APS,
                                   which could affect liquidity;
                              -    the Fund may be forced to redeem your shares
                                   to meet regulatory or rating agency
                                   requirements, or may voluntarily redeem your
                                   shares in certain circumstances;
                              -    in extraordinary circumstances, the Fund may
                                   not earn sufficient income from its
                                   investments to pay dividends;
                              -    if interest rates rise, the value of the
                                   Fund's investment portfolio will decline,
                                   reducing the asset coverage for the APS;
                              -    if an issuer of a Municipal Obligation in
                                   which the Fund invests experiences financial
                                   difficulty or defaults, there may be a
                                   negative impact on the income and assets of
                                   the Fund's portfolio; and
                              -    the Fund may invest up to 20% of its net
                                   assets in Municipal Obligations that are
                                   unrated but that, at the time of investment,
                                   have been determined by UBS Global AM to be
                                   of comparable quality to those that are rated
                                   investment grade.

                              For additional risks of investing in the Fund, see
                              "Investment Objectives and Policies" and
                              "Investment Risks."

Trading Market                APS are not listed on an exchange. Instead, you
                              may buy or sell APS through an auction that
                              normally is held weekly, by submitting orders to
                              or through a Broker-Dealer or other person that
                              has delivered a signed Master Purchaser's Letter
                              to the auction agent.

                              The Broker-Dealers may maintain a secondary
                              trading market in the APS outside of Auctions.
                              They have no obligation to do so, however, and
                              there can be no assurance that a secondary market
                              for the APS will develop or, if it does develop,
                              that it will provide holders with liquidity. APS
                              Series C will not be registered on any stock
                              exchange or on the Nasdaq Stock Market.

                              The first auction date for APS Series C is
                              ___________, 2003, and each subsequent auction
                              will normally be held on each [day of week]
                              thereafter, provided that the


                                        5


                              Fund, subject to certain conditions, may designate
                              any Subsequent Dividend Period as a Special
                              Dividend Period, which shall be such number of
                              consecutive days, whole months or whole years as
                              the Board of Directors shall specify, subject to
                              certain conditions. The start date for subsequent
                              dividend periods will normally be the business day
                              following the auction dates, unless the
                              then-current dividend period is a special dividend
                              period.

Dividends and                 The table below shows the dividend rate for the
Dividend Periods              initial dividend period on APS Series C. For
                              subsequent dividend periods, APS will pay
                              dividends based on a rate set at auction, normally
                              held weekly. In most instances, dividends are paid
                              [weekly], on the day following the end of the
                              dividend period. The rate set at auction will not
                              exceed the Maximum Rate. See "Description of
                              APS--Dividends and Dividend Periods."

                              In addition, the table below also shows the date
                              from which dividends on the APS will accumulate at
                              the initial rate, the dividend payment date for
                              the initial dividend period, and the day on which
                              dividends will normally be paid. If the day on
                              which dividends otherwise would be paid is a
                              Sunday, Monday or Tuesday that is not a Business
                              Day, then your dividends will be paid on the first
                              Business Day that falls after that day. If the day
                              on which dividends would otherwise be paid is a
                              Wednesday, Thursday, Friday, or Saturday that is
                              not a Business Day, then your dividends will be
                              paid on the first Business Day that falls prior to
                              such day.

                              Finally, the table below shows the number of days
                              of the initial dividend period for the APS.
                              Subsequent dividend periods generally will be
                              [seven days]. The dividend payment date for
                              special dividend periods of more than [seven days]
                              will be set out in the notice designating a
                              special dividend period. See "Description of

Special Tax                   Because under normal circumstances the Fund will
Considerations                invest substantially all of its assets in
                              municipal bonds, the income you receive will
                              ordinarily be exempt from federal income tax.
                              Taxable income or gain earned by the Fund will be
                              allocated proportionately to holders of APS and
                              common stock, based on the percentage of total
                              dividends paid to each class for that year.
                              Accordingly, certain specified APS dividends may
                              be taxable to holders of APS. Under certain
                              circumstances, the Fund will be required to pay
                              additional amounts to holders of APS in order to
                              offset the federal income tax effect of the
                              taxable income so allocated. See "Taxation" and
                              "Description of APS--Dividends and Dividend
                              Periods."

Ratings                       APS Series C is expected to be issued with a
                              rating of "Aaa" from Moody's and "AAA" from S&P.
                              In order to maintain these ratings, the Fund must
                              own portfolio securities of a sufficient value and
                              with adequate credit quality to meet the rating
                              agencies' guidelines. See "Description of
                              APS--Rating Agency Guidelines and Asset
                              Maintenance."

Redemption                    The Fund may be required to redeem APS if, for
                              example, the Fund does not meet an asset coverage
                              ratio required by law or to correct a failure to
                              meet a rating agency guideline in a timely manner.
                              The Fund voluntarily may redeem APS under certain
                              conditions. See "Description of APS--Redemption"
                              and "Description of APS--Rating Agency Guidelines
                              and Asset Maintenance."

Liquidation                   The liquidation preference for shares of APS
Preference                    Series C will be $50,000 per share plus
                              accumulated but unpaid dividends. See "Description
                              of APS--Liquidation Preference."

Voting Rights                 The holders of all outstanding series of APS,
                              voting as a separate class, have the right to
                              elect at least two directors of the Fund at all
                              times. Such holders also have the right to elect a
                              majority of the directors in the event that two
                              years' dividends on the preferred shares are
                              unpaid. In each case, the remaining directors will
                              be elected by holders of common stock and all
                              outstanding series of APS, voting together as a
                              single class. The holders of all outstanding
                              series of APS will vote as a separate class or
                              classes on certain other matters as required under
                              the Fund's Articles of Incorporation, the
                              Investment Company Act of 1940, as amended, and

                              FINANCIAL HIGHLIGHTS

The following financial highlights tables are intended to help you understand
the Fund's financial performance for the past 5 years, with respect to its
common stock and with respect to its currently outstanding APS. Certain
information reflects financial results for a single share of common stock, or
single share of APS, respectively. In the first table, 'total investment
return' represents the rate that an investor would have earned on an
investment in the Fund's common stock (assuming reinvestment of all
dividends and distributions).

The information in the financial highlights (for the three most recently
completed fiscal years), except for the six-month period ended March 31, 2003,
has been audited by Ernst & Young LLP, independent auditors, whose report
appears in the Fund's Annual Report to Shareholders. The Fund's financial
statements are included in the Fund's Annual and Semi-Annual Reports to
Shareholders. You may obtain the Fund's Annual and Semi-Annual Reports to
Shareholders without charge by calling 1-800-762 1000. The information in the
financial highlights for periods prior to the three most recently completed
fiscal years was audited by the Fund's previous independent auditor.

Investment Grade Municipal Income Fund Inc. (the "Fund") is a diversified,
closed-end management investment company and has registered under the Investment
Company Act of 1940 ("1940 Act"). The Fund was incorporated in the State of
Maryland on August 6, 1992. The Fund commenced investment operations on November
5, 1992 after an initial public offering of its common stock. The Fund issued
APS Series A and APS Series B in 1993. As of September 19, 2003, the Fund had
10,356,667 shares of common stock issued and outstanding. As of September 19,
2003, the Fund's total assets were $246,893,611, of which $80,000,000 was due to
APS Series A and B ($40,000,000 per Series).

The Fund's common stock is traded on the New York Stock Exchange, Inc. ("NYSE")
under the symbol "PPM." The common stock and the Auction Preferred Shares

                                 USE OF PROCEEDS

The net proceeds of this offering are estimated to be approximately $39,461,400,
after payment of underwriting discounts and offering expenses. Expenses related
to the issuance of the APS will be borne by the Fund and will reduce the net
asset value of the common stock. The Fund expects to invest the proceeds in
accordance with its investment objective and policies as soon as practicable,
but in no event later than three months from the closing of this offering.
Pending such investment, the Fund may invest the proceeds in high quality,
short-term, tax-exempt or taxable (if necessary) money market securities, or in
high quality Municipal Obligations with relatively low volatility (such as
pre-refunded securities).

                        INVESTMENT OBJECTIVE AND POLICIES

GENERAL

The Fund's investment objective is to achieve a high level of current income
that is exempt from federal income tax, consistent with the preservation of
capital.

To achieve its objective, the Fund normally invests substantially all of its
assets in a diversified portfolio of Municipal Obligations. Under normal
circumstances, the Fund invests at least 80% of its net assets in investment
grade Municipal Obligations, the income from which is exempt from regular
federal income tax. Municipal Obligations rated investment grade are those that,
at the time of investment, are rated within the four highest grades by Moody's
(Baa or higher) or S&P (BBB or higher) or have an equivalent rating from another
nationally recognized statistical rating organization. Municipal Obligations
rated Baa by Moody's are investment grade, but Moody's considers them to have
speculative characteristics. Changes in economic conditions or other
circumstances are more likely to lead to a weakened capacity for Municipal
Obligations that are rated BBB or Baa (or that have equivalent ratings) to make
principal and interest payments than is the case for higher grade Municipal
Obligations. The Fund may invest up to 20% of its net assets in Municipal
Obligations that are unrated but that, at the time of investment, have been
determined by UBS Global AM to be of comparable quality to those that are rated
investment grade.

Municipal Obligations are obligations issued by or on behalf of states, the
District of Columbia, territories or possessions of the United States or their
respective political subdivisions, agencies or instrumentalities, or by
multistate agencies or authorities, the interest on which is, in the opinion of
bond counsel, exempt from federal income tax. Municipal Obligations are issued
for various public purposes, including construction of public facilities, such
as airports, bridges, hospitals, housing, mass transportation, schools, streets
and water and sewer works. Other public purposes for which Municipal Obligations
may be issued include refinancing outstanding obligations and obtaining funds
for general operating expenses and for loans to other public institutions and
facilities. The principal types of Municipal Obligations in which the Fund may
invest are further described in Appendix A to this Prospectus and in the SAI.

Municipal Obligations include "public purpose" obligations, which generate
interest that is exempt from federal income tax and is not a "Tax Preference
Item", and qualified "private activity" obligations, which generate interest
that is exempt from federal income tax but that, if the obligations were issued
after August 7, 1986, is a Tax Preference Item. Up to 20% of the Fund's net
assets may be invested in Municipal Obligations the interest on which is a Tax
Preference Item. Under normal circumstances, the Fund will invest at least 80%
of its net assets in municipal obligations the interest on which is exempt from
the AMT.

The Fund may invest 25% or more of its total assets in a particular segment of
the Municipal Obligations market, such as hospital, housing or airport revenue
bonds, or in securities the interest on which is paid from revenues on similar
types of projects, if UBS Global AM determines that the yields available from
obligations in that market segment justify the potential increase in risk
resulting from a large investment in that market segment. Although such
obligations might be supported by the credit of governmental entities or by
non-governmental entities from a number of different industries, an economic,
business, political or other change affecting one such obligation might also
affect other obligations in the same market.

Moody's, S&P and the other nationally recognized statistical rating
organizations are private services that provide ratings of the credit quality of
debt obligations, including Municipal Obligations. It should be emphasized that
ratings are general and are not absolute standards of quality. Consequently,
Municipal Obligations with the same maturity, interest rate and rating may have
different market prices. Also, rating agencies may fail to make timely changes
in credit ratings in response to subsequent events, so that an issuer's
financial condition may be better or worse than is indicated by its rating.
Subsequent to its purchase by the Fund, an issue of Municipal Obligations may
cease to be rated or its rating may be reduced below the minimum rating required
for purchase by the Fund. UBS Global AM will consider such an event in
determining whether the Fund should continue to hold the obligation. In making
such a determination, UBS Global AM will consider such factors as its assessment
of the credit quality of the issuer of the security and the price at which the
security could be sold. UBS Global AM will engage in an orderly disposition of
downgraded Municipal Obligations to the


                                      12


extent necessary to ensure that the Fund's holdings of Municipal Obligations
rated below investment grade will not exceed 5% of the Fund's total assets. The
Fund does not purchase junk bonds. A description of Moody's and S&P's ratings is
included as Appendix A to the SAI.

The Fund may use options (both exchange-traded and OTC) to attempt to enhance
income (which would be taxable income) and also may attempt to "hedge" or manage
the overall risk of its investments by using options, futures contracts and
interest rate protection transactions. The Fund is not required to use
derivatives or other portfolio strategies to seek to enhance return or to seek
to hedge its portfolio, and UBS Global AM may elect not to do so. The Fund may
use derivatives as a substitute for taking a position in an underlying security
or other asset and/or as part of a strategy designed to reduce exposure to other
risks, such as interest rate risk. The Fund also may use derivatives to add
leverage to the portfolio and/or to hedge against increases in the Fund's costs
associated with the dividend payments on the preferred stock, including the APS.
The Fund's use of derivative instruments involves risks different from, and
possibly greater than, the risks associated with investing directly in
securities and other traditional investments. Derivatives are subject to a
number of risks such as liquidity risk, interest rate risk, credit risk,
leverage risk, the risk of ambiguous documentation and management risk. They
also involve the risk of mispricing or improper valuation and the risk that
changes in the value of the derivative may not correlate perfectly with the
underlying asset, rate or index. If UBS Global AM incorrectly forecasts market
values, interest rates or other applicable factors, the Fund's performance could
suffer. If the Fund invests in a derivative instrument it could lose more than
the principal amount invested. There can be no assurance that the Fund's
portfolio strategies will be effective. Some of the derivative strategies that
the Fund may use to seek to enhance its return are riskier than its hedging
transactions and have speculative characteristics. Such strategies do not
attempt to limit the Fund's risk of loss. The use of derivatives also may
increase the amount of taxes payable by stockholders. Also, suitable derivative
transactions may not be available in all circumstances, and there can be no
assurance that the Fund will engage in these transactions to reduce exposure to
other risks when that would be beneficial.

The Fund's investment objective and certain investment limitations described in
the SAI are fundamental policies that may not be changed without shareholder
approval. In addition, the Fund's policy of normally investing at least 80% of
its net assets in investment grade Municipal Obligations, the income from which
is exempt from regular federal income tax, may not be deviated from without
shareholder approval. The Fund will interpret its 80% policy (and a related 20%
policy with respect to investments in taxable investments as described below) as
if the following phrase appeared immediately after the words "net assets":
"(plus the amount of any borrowing for investment purposes)." If subsequent to
an investment, the Fund's 80% policy is no longer met (E.G., bonds are called
resulting in a large influx of cash), then under normal circumstances, the
Fund's future investments would be made in a manner that would bring the Fund's
investments back in line with the 80% threshold. All other investment policies
may be changed by the Fund's Board without shareholder approval.

OTHER INVESTMENT PRACTICES

Certain of the other investment practices in which the Fund may engage and that
are described below may give rise to federal income tax. Under normal
circumstances, the Fund does not intend to engage in those practices to a
significant extent. The Fund's ability to engage in certain of these investment
practices is limited by the rating agency guidelines applicable to the APS,
which are described further below.

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES. The Fund may purchase Municipal
Obligations on a when-issued basis, or may purchase or sell Municipal
Obligations for delayed delivery. In when-issued or delayed delivery
transactions, delivery of the securities occurs beyond normal settlement
periods, but no payment or delivery will be made by the Fund prior to the actual
delivery or payment by the other party to the transaction. The Fund will not
accrue income with respect to a when-issued or delayed delivery security prior
to its stated delivery date. When the Fund purchases securities on a when-issued
or delayed delivery basis, however, it immediately assumes the risks of
ownership, including the risk of price fluctuation. Depending on market
conditions, the Fund's when-issued and delayed delivery purchase commitments
could cause its net asset value per share (and thus its market 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. Failure to deliver a
security purchased on a when-issued or delayed delivery basis may result in a
loss or missed opportunity to make an alternative investment.


                                      13


SHORT-TERM TAX-EXEMPT AND TAXABLE INVESTMENTS. The Fund normally invests
substantially all of its assets in intermediate to longer-term Municipal
Obligations. However, in order to invest cash reserves or when, in the opinion
of UBS Global AM, no suitable longer-term Municipal Obligations are available,
the Fund may invest in high quality short-term Municipal Obligations that are
rated, at the time of investment, no lower than MIG-2 by Moody's, SP-2 by S&P
or, if unrated, that are determined by UBS Global AM to be of comparable quality
to Municipal Obligations that are rated at least MIG-2 or SP-2. These Municipal
Obligations may include variable or floating rate demand notes and similar
instruments that trade as short-term obligations. The Fund also may invest in
such high quality short-term Municipal Obligations for temporary defensive
purposes.

In addition, if in the opinion of UBS Global AM no suitable short-term Municipal
Obligations are available, the Fund temporarily may hold cash and, with respect
to up to 20% of its net assets, invest in taxable money market instruments,
including: (1) U.S. government securities; (2) high quality commercial paper
that is rated, at the time of purchase, no lower than Prime-2 by Moody's or A-2
by S&P or, if unrated, that is determined by UBS Global AM to be of comparable
quality to commercial paper that is rated at least Prime-2 or A-2; (3) bank
obligations (including certificates of deposit, time deposits and bankers'
acceptances of domestic banks); and (4) repurchase agreements with respect to
any of the foregoing. Interest earned from such taxable investments will be
taxable to stockholders as ordinary income when distributed. If the Fund were to
hold cash, the cash would not earn interest, and the Fund's yield would be lower
than if the cash had been invested.

REPURCHASE AGREEMENTS. The Fund is authorized to enter into repurchase
agreements 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 the Fund would purchase
securities from a bank or recognized securities dealer (or its affiliate) and
simultaneously commit to resell those securities to the counterparty at an
agreed-upon date or upon demand and at a price reflecting a market rate of
interest unrelated to the coupon rate or maturity of the purchased securities.
The Fund would maintain custody of the underlying securities prior to their
repurchase, either through its regular custodian or through a special
"tri-party" custodian or sub-custodian that maintains separate accounts for both
the Fund and its counterparty; thus, the obligation of the counterparty to pay
the repurchase price on the date agreed to or upon demand would, in effect, be
secured by such securities. If the value of such securities were less than the
repurchase price, plus any agreed-upon additional amount, the other party to the
agreement would be required to 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 would be 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 the repurchase
agreement becomes insolvent. The Fund intends to enter into repurchase
agreements only with banks and dealers in transactions believed by UBS Global AM
to present minimal credit risks in accordance with guidelines established by the
Fund's board of directors. UBS Global AM will review and monitor the
creditworthiness of such institutions under the board's general supervision.

REVERSE REPURCHASE AGREEMENTS. The Fund may enter into reverse repurchase
agreements with the same parties with whom it may enter into repurchase
agreements. Under a reverse repurchase agreement, the Fund would sell securities
and agree to repurchase (and the buyer would be required to resell) them at a
mutually agreed date or upon demand and at a price reflecting a market rate of
interest. At the time the Fund enters into a reverse repurchase agreement, it
will establish and maintain a segregated account with an approved custodian
containing cash or liquid securities, marked to market daily, having a value not
less than the repurchase price (including accrued interest). The market value of
securities sold under reverse repurchase agreements typically is greater than
the proceeds of the sale, and accordingly, the market value of the securities
sold is likely to be greater than the value of the securities in which the Fund
invests those proceeds. Thus, reverse repurchase agreements involve the risk
that the Fund might be unable to reacquire the securities that it has sold. In
the event the buyer of securities under a reverse repurchase agreement files for
bankruptcy or becomes insolvent, such buyer or its trustee or receiver may
receive an extension of time to determine whether to enforce the Fund's
obligation to


                                      14


repurchase the securities, and the Fund's use of the proceeds of the reverse
repurchase agreement may effectively be restricted pending such decision.
Reverse repurchase agreements will be treated as borrowings for purposes of
calculating the Fund's borrowing limitation discussed below. See "Rating Agency
Guidelines and Asset Maintenance."

LENDING OF PORTFOLIO SECURITIES. To attempt to enhance income (which would be
taxable income) the Fund is authorized to lend up to 33 1/3% of the total value
of its portfolio securities to broker-dealers or institutional investors that
UBS Global AM deems qualified, but only if doing so would not adversely affect
the rating of the APS by S&P and only when the borrower maintains acceptable
collateral with the Fund's custodian in an amount, marked to market daily, at
least equal to the market value of the securities loaned, plus accrued interest
and dividends. Acceptable collateral is limited to cash, U.S. government
securities and irrevocable letters of credit that meet certain guidelines
established by UBS Global AM. In determining whether to lend securities to a
particular broker-dealer or institutional investor, UBS Global AM will consider,
and during the period of the loan will monitor, all relevant facts and
circumstances, including the creditworthiness of the borrower. The Fund will
retain authority to terminate any loans at any time. The Fund may pay reasonable
administrative and custodial fees in connection with a loan and may pay a
negotiated portion of the interest earned on the cash held as collateral to the
borrower or placing broker. The Fund will receive reasonable interest on the
loan or a flat fee from the borrower, and amounts equivalent to any dividends,
interest or other distributions on the securities loaned. The Fund will regain
ownership of loaned securities to exercise beneficial rights, such as voting and
subscription rights, when regaining such rights is considered to be in the
Fund's interest.

OTHER PRACTICES. The Fund may invest up to 20% of its total 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, securities subject to contractual restrictions on
resale, repurchase agreements maturing in more than seven days and municipal
lease obligations (including certificates of participation) other than those
that UBS Global AM has determined are liquid pursuant to guidelines established
by the board of directors. To the extent the Fund invests in illiquid
securities, the Fund may not be able to readily liquidate such investments, and
would have to sell other investments if necessary to raise cash to meet its
obligations. The lack of a liquid secondary market for illiquid securities may
make it more difficult for the Fund to assign a value to those securities for
purposes of valuing the Fund's portfolio and calculating its net asset value.

The Fund also may invest in stand-by commitments with respect to Municipal
Obligations it purchases or holds.

BORROWINGS. The Fund is permitted to borrow money to finance common stock
repurchases and tender offers or for investment purposes from banks and other
entities or through reverse repurchase agreements in an amount not in excess of
33 1/3% of total assets (including the amount of the borrowing and any other
senior securities).

                                INVESTMENT RISKS

         RISK IS INHERENT IN ALL INVESTING. INVESTING IN ANY INVESTMENT COMPANY
SECURITY INVOLVES RISK, INCLUDING THE RISK THAT YOU MAY RECEIVE LITTLE OR NO
RETURN ON YOUR INVESTMENT OR EVEN THAT YOU MAY LOSE PART OR ALL OF YOUR
INVESTMENT. THEREFORE, BEFORE PURCHASING THE FUND'S APS, YOU SHOULD CONSIDER
CAREFULLY THE FOLLOWING RISKS THAT YOU ASSUME WHEN YOU INVEST IN THE FUND. AN
INVESTMENT IN THE FUND'S APS SHOULD NOT CONSTITUTE A COMPLETE INVESTMENT
PROGRAM.

RISKS OF INVESTING IN APS

AUCTION RISK. An attempt to sell APS at an auction may fail if the auction
fails; that is, if there are more APS offered for sale than there are buyers for
those shares. If sufficient clearing bids do not exist in an auction, the
applicable rate will be the maximum applicable rate, and in such event, owners
of APS wishing to sell will not be able to sell all, and may not be able to sell
any, of such shares in the auction. As a result, an investment in APS may be
illiquid. Neither the broker-dealers nor the Fund are obligated to purchase APS
in an auction or otherwise, nor is the Fund required to redeem APS in the event
of a failed auction. Also, if an investor places bid orders (orders to retain
APS) at an auction only at a specified rate, and that bid rate exceeds the
applicable rate set at the auction, the investor will not retain his APS.
Finally, if an investor elects to retain APS without specifying a rate below
which it would not wish to continue to hold its APS, and the


                                      15


auction sets a below-market rate, it may receive a lower rate of return on its
APS than the market rate. See "The Auction."

RATINGS AND ASSET COVERAGE RISK. While Moody's is expected to assign a rating of
"Aaa" to the APS and S&P is expected to assign a rating of "AAA" to the APS, the
ratings will not eliminate or necessarily mitigate the risks of investing in the
APS. A rating agency could withdraw, suspend or downgrade the rating assigned to
the APS, which may make shares of APS less liquid at an auction or in the
secondary market. In addition, the Fund may be forced to redeem APS to meet
regulatory or rating agency requirements. The Fund may also voluntarily redeem
APS under certain circumstances. See "Description of APS--Redemption." The Fund
may not redeem APS if such a redemption would cause the Fund to fail to meet
regulatory or rating agency asset coverage requirements, and the Fund may not
declare, pay or set apart for payment any dividend or other distribution if
immediately thereafter the Fund would fail to meet regulatory asset coverage
requirements. A material decline in the Fund's net asset value may impair the
Fund's ability to maintain its required levels of asset coverage on the APS, or,
in an extreme case, to pay dividends on APS. In addition, as a condition to its
receipt of "Aaa" and "AAA" ratings on the APS, the Fund has agreed to certain
investment limitations, which may restrict the Fund from making investments that
UBS Global AM believes would benefit the Fund. See "Rating Agency Guidelines"
for descriptions of the significance and limitations of the ratings on the APS
and of the asset maintenance and other tests the Fund must meet.

SECONDARY MARKET RISK. The broker-dealers may maintain a secondary trading
market in the APS outside of auctions; however, they have no obligation to do
so, and there can be no assurance that a secondary market for the APS will
develop or, if it does develop, that it will provide holders with a liquid
trading market (i.e., trading will depend on the presence of willing buyers and
sellers, and the trading price is subject to variables to be determined at the
time of the trade by the broker-dealers). The APS will not be registered on any
stock exchange or on any automated quotation system. Investors may not be able
to sell any or all of their APS between auctions, or may receive a purchase
price of less than $50,000 per share, plus unpaid dividends. An increase in the
level of interest rates likely will have an adverse effect on the secondary
market price of the APS.

INTEREST RATE RISK AND APS. The Fund issues shares of APS, which generally pay
dividends based on short-term interest rates. The Fund generally will purchase
Municipal Obligations that pay interest at fixed or adjustable rates. If
short-term interest rates rise, dividend rates on the shares of APS may rise so
that the amount of dividends paid to the holders of shares of APS exceeds the
income from the Fund's portfolio securities. Because income from the Fund's
entire investment portfolio (not just the portion of the portfolio purchased
with the proceeds of the APS offering) is available to pay dividends on the
shares of APS, dividend rates on the shares of APS would need to greatly exceed
the Fund's net portfolio income before the Fund's ability to pay dividends on
the shares of APS would be jeopardized. If market interest rates rise, this
could negatively impact the value of the Fund's investment portfolio, reducing
the amount of assets serving as asset coverage for the APS.

LEVERAGE RISK. The Fund uses financial leverage for investment purposes by
issuing APS. It is currently anticipated that, taking into account the APS being
offered in this Prospectus and the outstanding Series A APS and Series B APS,
the amount of leverage will represent approximately [__%] of the Fund's Managed
Assets. The Fund's leveraged capital structure creates special risks not
associated with unleveraged funds having similar investment objectives and
policies. These include the possibility of higher volatility of the net asset
value of the Fund and the APS' asset coverage.

RESTRICTIONS ON DIVIDENDS AND OTHER DISTRIBUTIONS. Restrictions imposed on the
declaration and payment of dividends or other distributions to holders of the
Fund's common shares and APS, both by the 1940 Act and by requirements imposed
by rating agencies, might impair the Fund's ability to maintain its
qualification as a regulated investment company for federal income tax
purposes. While the Fund intends to redeem APS to enable the Fund to
distribute its income as required to maintain its qualification as a regulated
investment company under the Internal Revenue Code ("Code"), there can be no
assurance that such actions can be effected in time to meet the Code
requirements. See "Taxation."

GENERAL RISKS OF INVESTING IN THE FUND


                                      16


MARKET RISK AND SELECTION RISK. Market risk is the risk that the bond market
will go down in value, including the possibility that the market will go down
sharply and unpredictably. Selection risk is the risk that the securities that
UBS Global AM selects will underperform the bond market, the relevant market
indices, or other funds with similar investment objectives and investment
strategies.

MUNICIPAL OBLIGATION MARKET RISK. The amount of public information available
about the Municipal Obligations in the Fund's portfolio is generally less than
that for corporate equities or bonds, and the investment performance of the Fund
may therefore be more dependent on the analytical abilities of UBS Global AM
than that of an equity fund or a taxable bond fund. The secondary market for
Municipal Obligations also tends to be less well-developed or liquid than many
other securities markets, which may adversely affect the Fund's ability to sell
its bonds at attractive prices or at prices approximating those at which the
Fund currently values them. The Fund may invest up to 20% of its assets in
illiquid securities. See "Investment Objective and Policies - Other Investment
Practices." The ability of municipal issuers to make timely payments of interest
and principal may be diminished during general economic downturns and as
governmental cost burdens are reallocated among federal, state and local
governments. In addition, laws enacted in the future by Congress or state
legislatures or referenda could extend the time for payment of principal and/or
interest, or impose other constraints on enforcement of such obligations, or on
the ability of municipalities to levy taxes. Issuers of Municipal Obligations
might seek protection under the bankruptcy laws. In the event of bankruptcy of
such an issuer, the Fund could experience delays in collecting principal and
interest and the Fund may not, in all circumstances, be able to collect all
principal and interest to which it is entitled. To enforce its rights in the
event of a default in the payment of interest or repayment of principal, or
both, the Fund may take possession of and manage the assets securing the
issuer's obligations on such securities, which may increase the Fund's operating
expenses. Any income derived from the Fund's ownership or operation of such
assets may not be tax-exempt.

INTEREST RATE AND CREDIT RISK. The Fund invests in Municipal Obligations,
which are subject to interest rate and credit risk. Interest rate risk is the
risk that prices of Municipal Obligations generally increase when interest
rates decline and decrease when interest rates increase. Prices of longer
term securities generally change more in response to interest rate changes
than prices of shorter term securities. The common share net asset value and
market price per share of the bonds in which the Fund will invest will
fluctuate more in response to changes in market interest rates than if the
Fund invested primarily in shorter-term bonds. The Fund's use of leverage by
the issuance of APS and its investments in certain other obligations, as
described above, may increase interest rate risk. Market interest rates for
investment grade Municipal Obligations in which the Fund will primarily invest
have recently declined significantly below the recent historical average rates
for such bonds and market interest rates are now near historical lows. These
levels increase the risk that these rates will rise in the future (which would
cause the value of the Fund's net assets to decline). Credit risk is the risk
that the issuer will be unable to pay the interest or principal when due. The
degree of credit risk depends on both the financial condition of the issuer
and the terms of the obligation. The Fund intends to invest in Municipal
Obligations that are rated investment grade by Moody's, S&P or another NRSRO.
It may also invest up to 20% of its net assets in unrated Municipal
Obligations that UBS Global AM believes are of comparable quality. Obligations
rated in the lowest investment grade category may have certain speculative
characteristics.

CALL AND REDEMPTION RISK. A Municipal Bond's issuer may call the bond for
redemption before it matures. If this happens to a Municipal Bond the Fund
holds, the Fund may lose income and may have to invest the proceeds in Municipal
Obligations with lower yields.

PRIVATE ACTIVITY BONDS. The Fund may invest in certain tax exempt securities
classified as "private activity bonds." These bonds may subject certain
investors in the Fund to the AMT. The Fund is not restricted with respect to
investing in private activity bonds that are not subject to the AMT. See
"Taxation."

INFLATION RISK. Inflation risk is the risk that the value of assets or income
from an investment will be worth less in the future as inflation decreases the
value of money. As inflation increases, the real value of the APS can decline.

PORTFOLIO STRATEGIES. The Fund may engage in various portfolio strategies both
to seek to hedge its portfolio against adverse effects from movements in
interest rates and in the securities markets generally and to seek to increase
the return


                                      17


of the Fund. These strategies include the use of derivatives, such as
exchange-traded financial futures and option contracts, options on futures
contracts or over-the-counter dealer transactions in caps, swap agreements or
swaptions. Such strategies subject the Fund to the risk that, if UBS Global AM
incorrectly forecasts market values, interest rates or other applicable factors,
the Fund's performance could suffer. The Fund is not required to use derivatives
or other portfolio strategies and may not do so. Income earned by the Fund from
many hedging activities will be treated as capital gain and, if not offset by
net realized capital loss, will be distributed to shareholders in taxable
distributions. There can be no assurance that the Fund's portfolio strategies
will be effective.

DERIVATIVES RISK. The Fund may use options (both exchange-traded and OTC) to
attempt to enhance income (which would be taxable income) and also may attempt
to "hedge" or manage the overall risk of its investments by using options,
futures contracts and interest rate protection transactions. The Fund is not
required to use derivatives or other portfolio strategies to seek to enhance
return or to seek to hedge its portfolio, and UBS Global AM may elect not to do
so. The Fund may use derivatives as a substitute for taking a position in an
underlying security or other asset and/or as part of a strategy designed to
reduce exposure to other risks, such as interest rate risk. The Fund also may
use derivatives to add leverage to the portfolio and/or to hedge against
increases in the Fund's costs associated with the dividend payments on the
preferred stock, including the APS. The Fund's use of derivative instruments
involves risks different from, and possibly greater than, the risks associated
with investing directly in securities and other traditional investments.
Derivatives are subject to a number of risks such as liquidity risk, interest
rate risk, credit risk, leverage risk, the risk of ambiguous documentation and
management risk. They also involve the risk of mispricing or improper valuation
and the risk that changes in the value of the derivative may not correlate
perfectly with the underlying asset, rate or index. If UBS Global AM incorrectly
forecasts market values, interest rates or other applicable factors, the Fund's
performance could suffer. If the Fund invests in a derivative instrument it
could lose more than the principal amount invested. There can be no assurance
that the Fund's portfolio strategies will be effective. Some of the derivative
strategies that the Fund may use to seek to enhance its return are riskier than
its hedging transactions and have speculative characteristics. Such strategies
do not attempt to limit the Fund's risk of loss. The use of derivatives also may
increase the amount of taxes payable by stockholders. Also, suitable derivative
transactions may not be available in all circumstances, and there can be no
assurance that the Fund will engage in these transactions to reduce exposure to
other risks when that would be beneficial.

ANTI-TAKEOVER PROVISIONS. The Fund's Articles of Incorporation include
provisions that could limit the ability of other entities or persons to
acquire control of the Fund or to change the composition of its Board of
Directors. Such provisions could limit the ability of shareholders to sell
their shares at a premium over prevailing market prices by discouraging a
third party from seeking to obtain control of the Fund. See "Description of
Capital Stock --Anti-Takeover Provisions of the Articles of Incorporation"

MARKET DISRUPTION. The war with Iraq, its aftermath and the continuing
occupation of Iraq are likely to have a substantial impact on the U.S. and world
economies and securities markets. The nature, scope and duration of the war and
occupation cannot be predicted with any certainty. Terrorist attacks on the
World Trade Center and the Pentagon on September 11, 2001 closed some of the
U.S. securities markets for a four-day period, and similar events cannot be
ruled out. The war and occupation, terrorism and related geopolitical risks have
led, and may in the future lead, to increased short-term market volatility and
may have adverse long-term effects on U.S. and world economies and markets
generally. Those events could also have an acute effect on individual issuers or
related groups of issuers. These risks could also adversely affect individual
issuers and securities markets, interest rates, auctions, secondary trading,
ratings, credit risk and other factors relating to the APS.

PORTFOLIO MANAGEMENT AND OTHER CONSIDERATIONS. If short term or medium term
rates increase or other changes in market conditions occur to the point where
the Fund's leverage could adversely affect holders of common shares (or in
anticipation of such changes), the Fund may attempt to shorten the average
maturity or duration of its investment portfolio in order to offset the negative
impact of leverage. The Fund also may attempt to reduce the degree to which it
is leveraged by redeeming preferred shares or otherwise by purchasing preferred
shares, including the APS. Purchases and redemptions of preferred shares,
including the APS, whether on the open market or in negotiated transactions, are
subject to limitations under the 1940 Act. In determining whether or not it is
in the best interest of the Fund and its shareholders to redeem or repurchase
outstanding preferred shares, the Fund may take into account a
variety of factors, including the following:


                                      18


     - market conditions,

     - the ratio of preferred shares to common shares, and

     - the expenses associated with such redemption or repurchase.

If market conditions subsequently change, the Fund may sell previously unissued
preferred shares or preferred shares that the Fund had issued but later
repurchased or redeemed.

                               DESCRIPTION OF APS

GENERAL

The Articles of Incorporation authorize the issuance of 200,000,000 shares of

authorized to classify and reclassify any unissued shares of capital stock from
time to time by setting or changing the preferences, conversion or other rights,
voting powers, restrictions, limitations as to dividends, qualifications or

In connection with the issuance of APS contemplated in this prospectus, the
Board has reclassified and authorized the issuance of ___ shares of its capital
stock as APS Series C.

DIVIDENDS AND DIVIDEND PERIODS

Dividends on APS Series C will accumulate at the Applicable Rate PER ANNUM from
the Date of Original Issue and will be payable, when, as and if declared by the
Board of the Fund out of legally available funds on [date] and [weekly]
thereafter, subject to certain exceptions. If the day on which dividends
otherwise would be paid is a Sunday, Monday or Tuesday that is not a Business
Day, then your dividends will be paid on the first Business Day that falls after
that Sunday, Monday or Tuesday. If the day on which dividends would otherwise be
paid is a Wednesday, Thursday, Friday or Saturday that is not a Business Day,
then your dividends will be paid on the first Business Day that falls prior to
such Wednesday, Thursday, Friday or Saturday. The first Auction Date for the APS
Series C is scheduled for _________, 2003. Subsequent Dividend Periods will be
[seven days] provided that the Fund, subject to certain conditions, may


                                      19


designate any Subsequent Dividend Period as a Special Dividend Period, which
shall be such number of consecutive days, whole months or whole years as the
Board shall specify, subject to certain conditions.

Dividends on APS Series C will be paid through the Securities Depository
(Depository Trust Company or any successor) on each Dividend Payment Date. The
Securities Depository, in accordance with its normal procedures, is expected to
distribute dividends on APS Series C in next-day funds to Agent Members, who in
turn are expected to distribute such dividend payments to the persons for whom
they are acting as agents. Each of the initial broker-dealers, however, has
indicated to the Fund that such broker-dealer or one of its affiliates will make
such dividend payments available in same-day funds on each Dividend Payment Date
to customers that use such broker-dealer or such affiliate as Agent Member.

The dividend rate for the initial Dividend Period will be __% PER ANNUM. For
each Subsequent Dividend Period, the dividend rate for APS Series C will be the
Applicable Rate PER ANNUM that the Auction Agent (_________ or any successor)
advises the Fund results from an auction, except as provided below. The dividend
rate that results from an auction will not be greater than the Maximum Rate.

The Maximum Rate will generally be the applicable percentage (set forth in the
Applicable Percentage Table, below) of the Reference Rate set forth below.
However, where APS Series C has or had a Special Dividend period (other than a
Special Dividend Period of 28 days or less) and an auction at which sufficient
clearing bids existed has not yet occurred for a Minimum Dividend Period for
such series (28 days for each series of APS) after such Special Dividend Period,
the Maximum Rate shall be the Reference Rate multiplied by the greater of

(A)  the dividend rate on shares of such APS series for the then-ending Rate
Period, or

(B)  the product of (x) the Applicable Percentage on such Auction Date, and (y)
the higher of (1) the "AA" Composite Commercial Paper Rate on such Auction Date
for the then-ending Rate Period of such series, if such Rate Period is less than
one year, or the Treasury Rate on such Auction Date for such Rate Period, if
such Rate Period is one year or greater, or (2) the "AA" Composite Commercial
Paper Rate on such auction date for such Special Dividend Period of such series,
if the Special Dividend Period is less than one year, or the Treasury Rate on
such auction date for the Special Dividend Period, if the Special Dividend
Period is one year or greater.

Where an auction date immediately precedes the first day of any proposed Special
Dividend Period of more than 28 days, the Maximum Rate shall be the applicable
percentage (set forth in the Applicable Percentage Table, below) multiplied by
the highest of (1) the Reference Rate on such auction date for the then-ending
Rate Period of such series, if such Rate Period is less than one year, or the
Treasury Rate on such auction date for such Rate Period, if such Rate Period is
one year or greater; (2) the Reference Rate on such auction date for the Special
Dividend Period of such series for which the auction is being held, if such
Special Dividend Period is less than one year, or the Treasury Rate on such
Auction date for the Special Dividend Period for which the auction is being
held, if such Special Dividend Period is one year or greater; or (3) the
Reference Rate on such auction date for a Minimum Dividend Period.

REFERENCE RATES; TREASURY RATES. The applicable Reference Rates and Treasury
Rates will be the rates announced on such auction date for the Business Day
immediately prior to such auction date.

The Reference Rate is, with respect to any Rate Period of less than one year,
the higher of (i) the "AA" Composite Commercial Paper Rate and (ii) the Taxable
Equivalent of the Short-Term Municipal Bond Rate. The applicable "AA" Composite
Commercial Paper Rates and Treasury Rates will be the rates announced on such
Auction Date for the Business Day immediately prior to such Auction Date.

"AA Composite Commercial Paper Rate," on any date for any Rate Period, means:
(i) (A) in the case of any Minimum Dividend Period or any Rate Period of between
7 and 35 days, the interest equivalent of the 30-day rate; provided, however, in
the case of any Minimum Dividend Period of 7 days or any Rate Period with 7
days, and if the "AA" Composite Commercial Paper Rate is being used to determine
the Applicable Rate when all of the outstanding APS are subject to submitted
hold orders, then the interest equivalent of the 7-day rate, and (B) in the case
of any Rate Period with more than 35 days, the interest equivalent of the
180-day rate, on commercial paper placed on behalf of issuers whose corporate
bonds are rated "AA"' by S&P or the equivalent of such rating by S&P or another
rating agency, as made available on a discount basis or otherwise by the Federal
Reserve Bank of New York for the Business Day immediately preceding such date;
or (ii) in the event that the Federal Reserve Bank of New York does not make
available any such rate, then the arithmetic average of such rates, as quoted on
a discount basis or otherwise, by the Commercial Paper Dealers to the Auction
Agent for the close of business on the Business Day next preceding such date.


                                      20


"Taxable Equivalent of the Short-Term Municipal Bond Rate" on any date means 90%
of the quotient of (a) the PER ANNUM rate expressed on an Interest Equivalent
basis equal to the Kenny S&P 30-day High Grade Index or any successor index (the
"Kenny Index"), made available for the Business Day immediately preceding such
date but in any event not later than 8:30 A.M., Eastern time, on such date by
Kenny Information Systems Inc. or any successor thereto, (provided that the use
of such successor will not result in a reduction or withdrawal of the rating of
the APS by Moody's, if Moody's is then rating the APS, or by S&P, if S&P is then
rating the APS) based on 30-day yield evaluations at par of bonds, the interest
on which is excludable for regular federal income tax purposes, of "high grade"
component issuers selected by Kenny Information Systems Inc or any such
successor from time to time in its discretion, which component issuers shall
include, without limitation, issuers of general obligation bonds but shall
exclude any bonds the interest on which constitutes an item of tax preference
under section 57(a)(5) of the Internal Revenue Code or successor provisions, for
purposes of the AMT, divided by (b) 1.00 minus the Marginal Tax Rate (expressed
as a decimal); provided, however, that if the Kenny Index is not made so
available by 8:30 A.M., Eastern time, on such date by Kenny Information Systems
Inc. or any successor, the Taxable Equivalent of the Short-Term Municipal Bond
Rate shall mean the quotient of (i) the PER ANNUM rate expressed on an Interest
Equivalent basis equal to the most recent Kenny Index so made available for any
preceding Business Day, divided by (ii) 1.00 minus the Marginal Tax Rate
(expressed as a decimal).

For the purposes of the foregoing, "Treasury Rate," on any date for any Rate
Period, means: (i) the yield on the most recently auctioned non-callable direct
obligations of the US Government (excluding " flower" bonds) with a remaining
maturity within three months of the duration of such Rate Period, as quoted in
THE WALL STREET JOURNAL on such date for the Business Day next preceding such
date; or (ii) in the event that any such rate is not published by THE WALL
STREET JOURNAL, then the arithmetic average of the yields (expressed as an
interest equivalent in the case of a Rate Period which is one year or less and
expressed as a bond equivalent in the case of any longer Rate Period) on the
most recently auctioned non-callable direct obligations of the US Government
(excluding "flower" bonds) with a remaining maturity within three months of the
duration of such Rate Period as quoted on a discount basis or otherwise by the
US Government Securities Dealers to the Auction Agent for the close of business
on the Business Day immediately preceding such date.

The "Applicable Percentage" will be a percentage, determined as set forth below,
based on the prevailing rating of the APS in effect at the close of business on
the Business Day next preceding such Auction Date:



                                                       APPLICABLE
          PREVAILING RATING                            PERCENTAGE
          -----------------                            ----------
                                                           
          "aa3"/AA- or higher                                 __%

          "a3"/A-                                             __%

          "baa3"/BBB-                                         __%

          "ba3"/BB-                                           __%

          Below "ba3"/BB-                                     __%


However, if the Fund has notified the Auction Agent of its intent to allocate
income that is taxable for federal income tax purposes to the APS prior to any
Auction, for purposes of determining the Maximum Rate with respect to such
auction, the applicable percentage in the foregoing table shall be divided by
the quantity (1 minus the Marginal Tax Rate), only to the extent of the portion
of the dividend on the APS for such Rate period that represents the allocation
of taxable income to APS. If the APS are rated by only one rating agency, such
rating will be the prevailing rating. If the ratings for the APS are split
between two of the foregoing categories, the lower rating will determine the
prevailing rating.

If an auction for any series of APS is not held when scheduled for any reason,
or if the Fund fails to deposit in a timely manner with the Auction Agent the
full amount of any dividend on, or redemption price of, shares of any series of
APS, and such failure has not been cured as set forth below prior to any
succeeding Subsequent Dividend Period, the dividend rate on the shares of such
series for any such Subsequent Dividend Period will be the Maximum Rate on the
date on which the auction was scheduled to be held.

If the Fund fails to deposit in a timely manner with the Auction Agent the full
amount of any dividend on, or redemption price of, any shares of any APS series
during any Rate Period for that series, and does not cure its failure to do so
or pay a


                                      21


late charge, if applicable, prior to 12:00 Noon (Eastern time) on the third
Business Day next following the failure, auctions for such series will be
suspended until the failure is cured. The dividend rate for such shares of APS
for each dividend period commencing after that failure (including the dividend
period, if any, during which the failure is cured) shall be a rate PER ANNUM
equal to the Maximum Rate on the Auction Date for each such dividend period (but
with the prevailing rating for such shares, for purposes of determining such
Maximum Rate, being deemed to be "Below "ba3"/BB-").

ADDITIONAL DIVIDENDS. If the Fund allocates any net capital gain or other income
taxable for Federal income tax purposes to a dividend paid on APS without having
provided advance notice thereof to the Auction Agent (a "Taxable Allocation"),
whether or not such allocation is made retroactively as a result of the
redemption of all or a portion of the APS or the liquidation of the Fund, the
Fund shall pay an additional dividend.

Simultaneously with such allocation, if practicable, but in no event later than
270 days after the end of the Fund's taxable year for which a Taxable Allocation
is made, provide notice thereof to the Auction Agent and to each APS shareholder
during such taxable year at such shareholder's address as it last appears on the
stock books of the Fund. The Fund will, within 30 days of notifying the Auction
Agent, pay to the Auction Agent (who will then distribute to such holders of
shares of APS), out of legally available funds, an amount equal to the aggregate
Additional Dividends (as defined below) with respect to all Taxable Allocations
made to such holders for the taxable year in question. See "Taxation."

The additional dividend will be in an amount approximately equal to the amount
of taxes paid by APS shareholders on the Taxable Allocation and the additional
dividend, provided that the additional dividend will be calculated (i) without
consideration being given to the time value of money; (ii) assuming that no
holder of APS is subject to the AMT with respect to dividends received from the
Fund; and (iii) assuming that each Taxable Allocation would be taxable in the
hands of APS shareholder at the maximum marginal regular federal individual
income tax rate applicable to ordinary income or net capital gain, as
applicable, or the maximum marginal regular federal corporate income tax rate,
whichever is greater, in effect during the taxable year in question.

RATING AGENCY GUIDELINES AND ASSET MAINTENANCE

The Fund is required under Moody's and S&P guidelines to maintain assets having
in the aggregate a Discounted Value at least equal to the APS Basic Maintenance
Amount. Moody's and S&P have each established separate guidelines for
determining Discounted Value. To the extent any particular portfolio holding
does not satisfy the applicable rating agency's guidelines, all or a portion of
such holding's value will not be included in the calculation of Discounted Value
(as defined by such rating agency). The Moody's and S&P guidelines do not impose
any limitations on the percentage of the Fund's assets that may be invested in
holdings not eligible for inclusion in the calculation of the Discounted Value
of the Fund's portfolio. The amount of such assets included in the portfolio at
any time may vary depending upon the rating, diversification and other
characteristics of the eligible assets included in the portfolio, although it is
not anticipated that in the normal course of business the value of such assets
would exceed 20% of the Fund's total assets. The APS Basic Maintenance Amount
includes the sum of (a) the aggregate liquidation preference of shares of APS
then outstanding and (b) certain accrued and projected payment obligations of
the Fund.

The Fund is also required under the 1940 Act and rating agency guidelines to
maintain, with respect to shares of APS, as of the last Business Day of each
month in which any such shares are outstanding, asset coverage of at least 200%
with respect to all outstanding senior securities which represent the Fund's
equity securities, including APS (or such other asset coverage as may in the
future be specified in or under the 1940 Act as the minimum asset coverage for
senior securities which represent equity securities of a closed-end investment
company as a condition of declaring dividends on its common stock) ("1940 Act
APS Asset Coverage").


                                      22


Based on the composition of the Fund's portfolio [and market conditions] as of
September 30, 2003, the 1940 Act APS Asset Coverage with respect to the APS,
assuming the issuance of APS Series C and after giving effect to the deduction
of underwriting discounts and offering expenses relating to APS Series C,
estimated at $538,600, would be computed as follows:

     Value of total Fund assets less liabilities not         $____
             constituting senior securities
            --------------------------------          =  -------------- =   __%
       Senior securities representing indebtedness        $120,000,000
          plus liquidation value of the APS

In the event the Fund does not timely cure a failure to maintain (a) a
Discounted Value of its portfolio equal to the APS Basic Maintenance Amount or
(b) the 1940 Act APS Asset Coverage, in each case in accordance with the
requirements of the rating agency or agencies then rating the shares of APS, the
Fund will be required to redeem shares of APS as described under
"Redemption--Mandatory Redemption" below.

The Fund may, but is not required to, adopt any modifications to the guidelines
that may hereafter be established by Moody's or S&P. Failure to adopt any such
modifications, however, may result in a change in the ratings described above or
a withdrawal of ratings altogether. In addition, any rating agency providing a
rating for the shares of APS may, at any time, change or withdraw any such
rating. The Board may, without shareholder approval, amend, alter or repeal any
or all of the definitions and related provisions which have been adopted by the
Fund pursuant to the rating agency guidelines in the event the Fund receives
written confirmation from Moody's or S&P, or both, as appropriate, that any such
amendment, alteration or repeal would not impair the ratings then assigned by
Moody's and S&P to shares of APS.

As recently described by Moody's and S&P, a preferred stock rating is an
assessment of the capacity and willingness of an issuer to pay preferred stock
obligations. The ratings on the shares of APS are not recommendations to
purchase, hold or sell those shares, inasmuch as the ratings do not comment as
to market price or suitability for a particular investor. The rating agency
guidelines described above also do not address the likelihood that an owner of
shares of APS will be able to sell such shares in an auction or otherwise. The
ratings are based on current information furnished to Moody's and S&P by the
Fund and the Advisor and information obtained from other sources. The ratings
may be changed, suspended or withdrawn as a result of changes in, or the
unavailability of, such information. The common shares have not been rated by a
nationally recognized statistical rating organization.

A rating agency's guidelines will apply to shares of APS only so long as such
rating agency is rating such shares. The Fund pays certain fees to Moody's or
S&P, or both, for rating shares of APS.

REDEMPTION

MANDATORY REDEMPTION. The Fund will be required to redeem, at the Mandatory
Redemption Price ($50,000 per share of APS plus an amount equal to accumulated
but unpaid dividends thereon to the date fixed for redemption (whether or not
earned or declared)), certain of the APS to the extent permitted under the 1940
Act and Maryland law, if the Fund fails to maintain a Discounted Value of
Moody's Eligible Assets or S&P Eligible Assets in an amount greater than or
equal to the APS Basic Maintenance Amount or fails to maintain the 1940 Act APS
Asset Coverage and such failure is not cured on or before the APS Basic
Maintenance Cure Date or the 1940 Act Cure Date (herein respectively referred to
as a "Cure Date"), as the case may be. Any such redemption will be limited to
the number of APS necessary to restore the APS Basic Maintenance Amount or the
1940 Act APS Asset Coverage, as the case may be.

OPTIONAL REDEMPTION. The Fund, at its option, may redeem shares of any APS
series, in whole or in part, out of legally available funds. Any optional
redemption will occur on the second Business Day next preceding any Dividend
Payment Date applicable to shares of such APS series called for redemption, at
the optional redemption price of $50,000 per APS share plus, in the case of a
Special Dividend Period of 365 days or more, an amount equal to accumulated but
unpaid dividends thereon to the date fixed for redemption and a premium, if any,
determined by the Board (unless the Board has determined that no share of such
series of APS will be subject to optional redemption).

LIQUIDATION PREFERENCE

Upon a liquidation of the Fund, whether voluntary or involuntary, the holders of
any APS series then outstanding will be entitled to receive and to be paid out
of the Fund's assets available for distribution to its shareholders, before any
payment


                                      23


or distribution shall be made on Common Stock or any other class of stock of the
Fund ranking junior to the APS upon liquidation, an amount equal to the
liquidation preference with respect to that APS series. The liquidation
preference for the APS is $50,000 per share, plus an amount equal to all
dividends thereon (whether or not earned or declared) accumulated but unpaid to
the date of final distribution, in same-day funds, together with any applicable
Additional Dividends (as defined under "Description of the APS") in connection
with the liquidation of the Fund. After the payment to the holders of the APS of
the full preferential amounts provided for as described herein, the holders of
APS as such shall have no right or claim to any of the remaining assets of the
Fund.

Neither the sale of all or substantially all of the property or business of the
Fund, nor the merger or consolidation of the Fund into or with any other
corporation, nor the merger or consolidation of any other corporation into or
with the Fund shall be a liquidation, whether voluntary or involuntary, for the
purposes of this paragraph.

VOTING RIGHTS

Holders of the APS generally will have equal voting rights with holders of
Common Stock (one vote per share) and generally will vote together with holders
of Common Stock as a single class. However, in connection with the election of
the Fund's directors, holders of outstanding shares of preferred stock,
including any APS, voting as a separate class, are entitled to elect two of the
Fund's directors; the remaining directors are elected by Common Stockholders and
preferred stockholders, including any APS, voting as a single class. In
addition, if at any time dividends (whether or not earned or declared) on any
outstanding preferred stock, including the APS, shall be due and unpaid in an
amount equal to two full years' dividends thereon, then the holders of the
preferred stock, including any outstanding APS, voting as a separate class, will
be entitled to elect a majority of the total number of directors of the Fund so
long as such dividends remain unpaid.

So long as any of the APS are outstanding, the Fund will not, without the
affirmative vote of a majority of the outstanding APS, determined with reference
to a "majority of outstanding voting securities" as that term is defined in
Section 2(a)(42) of the 1940 Act (voting separately as one class): (a)
authorize, create or issue any class or series of stock ranking prior to or on a
parity with the APS with respect to the payment of dividends or the distribution
of assets upon liquidation or increase the authorized amount of APS (except that
the Fund may, without the vote of the holders of APS, authorize, create or issue
classes or series of preferred stock ranking on a parity with the APS with
respect to the payment of dividends and the distribution of assets upon
liquidation subject to continuing compliance by the Fund with the asset coverage
requirement of the 1940 Act and APS basic maintenance amount requirements
established by Moody's or S&P; provided that the Fund obtains written
confirmation from Moody's (if Moody's is then rating the APS) and S&P (if S&P is
then rating the APS) that the issuance of any such additional class or series of
preferred stock would not impair the rating then assigned by such rating agency
to the APS); (b) amend, alter or repeal the Fund's Articles of Incorporation
insofar as they relate to the APS ("APS Provisions"), whether by merger,
consolidation or otherwise, so as to affect any preference, right or power of
such APS or the holders thereof, provided that (i) none of the actions permitted
by the exception to (a) above will be deemed to affect such preferences, rights
or powers and (ii) the authorization, creation and issuance of classes or series
of stock ranking junior to the APS with respect to payment of dividends and the
distribution of assets upon liquidation will be deemed to affect such
preferences, rights or powers only if Moody's or S&P is then rating the Fund and
such issuance would, at the time thereof, cause the Fund not to satisfy the
assets coverage or APS basic maintenance amounts referred to above; or (c) file
a voluntary application for relief under federal bankruptcy law or any similar
application under state law for so long as the Fund is solvent and does not
foresee becoming insolvent.

The Fund's Board may, however, without approval of the holders of APS, amend,
alter or repeal any or all of the definitions required to be contained in the
APS Provisions by the rating agencies in the event the Fund receives written
confirmation from the appropriate rating agency that any such amendment,
alteration or repeal would not impair the ratings then assigned to the APS by
such rating agency. Unless a higher percentage is provided for under
"Description of Capital Stock--Certain Anti-Takeover Provisions of the Articles
of Incorporation," the affirmative vote of the holders of a majority of the
outstanding APS, voting as a separate class, will be required to approve any
plan of reorganization (as such term is defined under the 1940 Act) adversely
affecting such shares or any action requiring a vote of security holders under
Section 13(a) of the 1940 Act including, among other things, changes in the
Fund's investment objective or changes in the investment restrictions described
as fundamental policies under "Investment Limitations" in the SAI. The class
vote of holders of APS described above will in each case be in addition to a
separate vote of the requisite percentage of


                                      24


shares of Common Stock necessary to authorize the action in question. To the
extent permitted by the 1940 Act, each series of APS may vote as a separate
series in certain circumstances.

The foregoing voting provisions will not apply with respect to APS if, at or
prior to the time when a vote is required, such APS shall have been (i) redeemed
or (ii) called for redemption and sufficient funds shall have been deposited in
trust to effect such redemption. See "Description of APS-Voting Rights" in the
SAI.

                                   THE AUCTION

The APS Provisions provide that the Applicable Rate per annum for each dividend
period after the initial dividend period with respect to each APS series shall
be the rate PER ANNUM that the Auction Agent advises has resulted from an
auction conducted in accordance with the auction procedures ("Auction
Procedures") set forth in the APS Provisions and summarized below. In such an
auction, persons determine to hold or offer to sell or, based on dividend rates
bid by them, offer to purchase or sell shares of such series of APS.

AUCTION AGENCY AGREEMENT. The Fund will enter into an auction agency agreement
with the auction agent (currently, Deutsche Bank), which provides, among other
things, that the auction agent will follow the auction procedures to determine
the applicable rate for shares of each series of APS, so long as the applicable
rate for shares of such APS series is to be based on the results of an auction.

The auction agent may terminate the auction agency agreement upon ___ days'
notice to the Fund. If the auction agent should resign, the Fund will use its
best efforts to enter into an agreement with a successor auction agent
containing substantially the same terms and conditions as the auction agency
agreement. The Fund may remove the auction agent provided that, prior to
removal, the Fund has entered into a replacement agreement with a successor
auction agent.

BROKER-DEALER AGREEMENTS. Each auction requires the participation of one or more
broker-dealers. The auction agent will enter into agreements with several
broker-dealers selected by the Fund, which provide for the participation of
those broker-dealers in auctions for APS Shares.

The auction agent will pay to each Broker-dealer after each auction, from funds
provided by the Fund, a service charge at the annual rate of ____% in the case
of any auction before a dividend period of 364 days or less, or a percentage
agreed to by the Fund and the Broker-dealers, in the case of any auction before
a dividend period of 365 days or longer, of the purchase price of APS Shares
placed by a broker-dealer at the auction.

The Fund may request the auction agent to terminate one or more Broker-Dealer
Agreements at any time [upon ___days' notice], provided that at least one
Broker-Dealer Agreement is in effect after termination of the agreements.

AUCTION PROCEDURES

On each Auction Date (the Business Day prior to the beginning of each Rate
Period after the Initial Dividend Period), each existing shareholder may submit
orders through a broker-dealer to the Auction Agent as follows:

     HOLD ORDER     indicating its desire to hold without regard to the
                    Applicable Rate for the next Rate Period.

     BID            indicating its desire to sell if the Applicable Rate for the
                    next Rate Period is less than the rate specified in such
                    Bid.

     SELL ORDER     indicating its desire to sell without regard to the
                    Applicable Rate for the next Rate Period.

An "existing shareholder" of APS series shares is a person who has signed, or on
whose behalf a broker-dealer has signed, a Master Purchaser's Letter and is
listed as the beneficial owner of such APS shares in the records of the Auction
Agent. An existing shareholder may submit different types of orders in an
auction with respect to that shareholder's shares of APS then held. An existing
shareholder that offers to purchase additional shares of APS is, for purposes of
such offer, treated as a "potential shareholder" as described below. Bids of
existing shareholders with rates higher than the Maximum Rate on the auction
date will be treated as sell orders. With respect to an auction preceding a Rate
Period of less than 90 days, a hold order will be deemed to have been submitted
on behalf of an existing shareholder if an order is not submitted on behalf of
such existing shareholder for any reason, including the failure of a
broker-dealer to submit such existing shareholder's order to the auction agent.
With respect to an auction preceding a Rate Period of 90 days or greater, a sell
order will be deemed to have been submitted on behalf of an existing shareholder
if an order is not


                                      25


submitted on behalf of such existing shareholder for any reason, including the
failure of a broker-dealer to submit such existing shareholder's order to the
Auction Agent.

"Potential shareholders" of shares of any series of APS may submit bids in which
they will offer to purchase shares of such series of APS if the applicable rate
for the next Rate Period is not less than the rate specified in such bid. A bid
by a potential shareholder specifying a rate higher than the Maximum Rate will
not be accepted.

If sufficient clearing bids exist (that is, if the number of shares of a
particular series of APS subject to bids by potential shareholders with rates
equal to or lower than the Maximum Rate is at least equal to the number of
shares of such series of APS subject to sell orders by existing shareholders),
the applicable rate for such series will be the lowest rate specified in the
submitted bids which, taking into account such rate and all lower rates bid by
existing shareholders and potential shareholders, would result in existing
shareholders and potential shareholders owning all the shares of such series of
APS available for purchase in the auction. If sufficient clearing bids do not
exist, the applicable rate will be the Maximum Rate on the auction date, and, in
such event, existing shareholders that have submitted sell orders may not be
able to sell in such auction all shares of such series of APS subject to such
sell orders. If all existing shareholders of such series of APS submit or are
deemed to have submitted hold orders, the applicable rate will be the product of
(i) (a) the Reference Rate on such auction date for the Rate Period for which
the auction is held, if such Rate Period is less than one year, or (b) the
Treasury Rate on such auction date for such Rate Period, if such Rate Period is
one year or longer; and (ii) (1 minus the Marginal Tax Rate); provided, however,
that if the Fund has notified the Auction Agent of its intent to allocate to the
APS in such Rate Period any net capital gains or other income that is taxable
for federal income tax purposes, the Applicable Rate with respect to that
portion of the dividend on the APS for such Rate Period that represents the
allocation of net capital gains or other income taxable for Federal income tax
purposes will be the rate described in the preceding clause (i)(a) or (i)(b), as
applicable, without being multiplied by the factor set forth in clause (ii).

The Auction Procedures include a PRO RATA allocation of shares for purchase and
sale, which may result in an existing shareholder continuing to hold or selling,
or a potential holder purchasing, a number of shares of APS that is fewer than
the number of shares of APS specified in its order.

A bid placed by an existing shareholder specifying a rate greater than the
applicable rate determined in the auction or a sell order shall constitute an
irrevocable offer to sell the shares of such series of APS subject thereto, in
each case at a price per share equal to $50,000. A bid placed by a potential
shareholder shall constitute an irrevocable offer to purchase the shares of such
series of APS subject thereto at a price per share equal to $50,000 if the rate
specified in such bid is less than or equal to the applicable rate determined in
the auction. Settlement of purchases and sales will be made on the next Business
Day (also a Dividend Payment Date) after the auction date through the Securities
Depository. Purchasers will make payment through their Agent Members in same-day
funds to the Securities Depository against delivery to their respective Agent
Members. The Securities Depository will make payment to the sellers' Agent
Members in accordance with the Securities Depository's normal procedures, which
currently provide for payment against delivery by their Agent Members in
same-day funds.

MASTER PURCHASER'S LETTER

Each prospective purchaser of shares of any series of APS or its broker-dealer
will be required to sign and deliver a Master Purchaser's Letter to the Auction
Agent in which such prospective purchaser or its broker-dealer will agree, among
other things, that

          (i)     dispositions of shares of such series of APS may be made only
     pursuant to a bid or a sell order placed in an auction, or to or through a
     broker-dealer or to a person that has delivered a signed Master Purchaser's
     Letter to the Auction Agent; provided that in the case of all transfers
     other than those pursuant to auctions, the existing shareholders of the
     shares so transferred, its Agent Member or its broker-dealer advises the
     Auction Agent of such transfer; and

          (ii)    ownership of shares of a series of APS will be maintained in
     book entry form by the Securities Depository for the account of such
     prospective purchaser's Agent Member, which, in turn, will maintain records
     of the prospective purchaser's beneficial ownership.

EACH PROSPECTIVE PURCHASER SHOULD CONSULT ITS BROKER-DEALER TO DETERMINE WHETHER
TO SIGN A MASTER PURCHASER'S LETTER. IF THE BROKER-DEALER SUBMITS ORDERS FOR
PROSPECTIVE PURCHASERS LISTING THE BROKER-DEALER AS THE EXISTING


                                      26


SHAREHOLDER OR THE POTENTIAL SHAREHOLDER, A MASTER PURCHASER'S LETTER SIGNED BY
THE PROSPECTIVE PURCHASER MAY NOT BE REQUIRED.

An execution copy of the Master Purchaser's Letter is included inside the back
cover of this Prospectus. Execution by a prospective purchaser or its
broker-dealer of a Master Purchaser's Letter is not a commitment to purchase
shares of APS in the offering being made by this Prospectus or in any auction,
but is a condition precedent to a purchaser's purchasing shares of APS. In
addition, acceptance of a Master Purchaser's Letter is not a guarantee that
shares of APS will be available for purchase.

SECONDARY MARKET TRADING

A broker-dealer may maintain a secondary trading market in the APS outside of
Auctions. The broker-dealers have no obligation to do so, however, and there can
be no assurance that a secondary market for the APS will develop or, if it does
develop, that it will provide holders with liquidity of investment. The APS will
not be registered on any stock exchange or on The Nasdaq Stock Market.

                                    TAXATION

The following is a description of certain US Federal income tax consequences to
an investor of acquiring, holding and disposing of APS shares of the Fund. The
discussion reflects applicable tax laws of the US as of the date of this
prospectus, which tax laws may be changed or subject to new interpretations by
the courts or the Internal Revenue Service ("IRS") retroactively or
prospectively. Investors are urged to consult their own tax advisors to
determine the tax consequences to them of investing in the Fund.

The Fund intends to continue to qualify for treatment as a regulated investment
company ("RIC") under Subchapter M of the Code. For each taxable year that the
Fund so qualifies, it will be relieved of federal income tax on that part of its
investment company taxable income (consisting generally of taxable net
investment income, net short-term capital gain and net realized gains from
certain hedging transactions) and net capital gain that is distributed to its
stockholders.

In general, dividends on the APS will be exempt from regular federal income tax
in the hands of holders of such APS, subject to the possible application of the
AMT. However, the Fund is required to allocate net capital gains and other
income that is taxable for federal income tax purposes, if any, proportionately
between the common stock and the APS. The Fund may notify the Auction Agent of
the amount of any net capital gains or other income that is taxable for federal
income tax purposes that is to be included in any dividend on the APS prior to
the Auction establishing the Applicable Rate for such dividend. The Auction
Agent will in turn notify each broker-dealer whenever it receives any such
notice from the Fund, and each broker-dealer will notify its Existing Holders
and Potential Holders, as provided in its Broker-Dealer Agreement. The amount of
taxable income allocable to the APS will depend upon the amount of such income
realized by the Fund, but is not generally expected to be significant.

If the Fund retroactively allocates any net capital gains or other income
taxable for federal income tax purposes to the APS without having given advance
notice thereof, as described above, by reason of the fact that such allocation
is made as a result of (i) the realization of net capital gains or other income
taxable for federal income tax purposes, (ii) the redemption of all or a portion
of the outstanding APS or (iii) the liquidation of the Fund, the Fund will make
certain payments to holders of APS to which such allocation was made to
substantially offset the tax effect thereof. See "Description of APS-Dividends
and Dividend Periods." In no other instance, including any holder of APS being
subject to the AMT, will the Fund be required to make payments to holders of APS
to offset the tax effect of any reallocation of net capital gains or other
taxable income.

Because the Fund may from time to time invest up to 20% of its net assets in
Municipal Obligations bearing income that is taxable under the AMT, the APS may
not be an appropriate investment for investors who are subject to the AMT or who
would become subject to the AMT by reason of an investment in the Fund.

For a further discussion of tax considerations affecting the Fund and the
Shareholders, see "Taxation" in the SAI.

                             MANAGEMENT OF THE FUND

DIRECTORS AND OFFICERS. The overall management of the business and affairs of
the Fund is vested in its Board. The Board approves all significant agreements
between the Fund and persons or companies furnishing services to it, including

INVESTMENT ADVISOR. Subject to the supervision of the Fund's Board, investment
advisory and administration services are provided to the Fund by UBS Global AM
pursuant to an Investment Advisory and Administration Contract dated October 15,
1992 ("Advisory and Administration Contract"). UBS Global AM's principal
business address is 51 West 52nd Street, New York, New York 10019-6114. UBS

Pursuant to the Advisory and Administration Contract, UBS Global AM provides a

compensation for its services, UBS Global AM is entitled to receive a fee,
computed weekly and paid monthly, in an amount equal to the annual rate of 0.90%
of the Fund's average weekly net assets. UBS Global AM has agreed to waive 0.20%
of this management fee, so that the effective management fee for the Fund is
0.70%. This waiver will continue indefinitely unless the Board agrees to any
change.

Effective May 20, 2002, William Veronda assumed primary responsibility for the

                           DESCRIPTION OF COMMON STOCK

GENERAL

The Fund is authorized to issue 200,000,000 shares of capital stock, $.001 par
value, which, as of September 19, 2003, is classified as 800 shares of APS
series A, 800 shares of APS series B, and 199,998,400 shares of common stock. In
connection with this offering, __ shares of the Fund's capital stock will be
reclassified and will be issued as APS Series C. See "Description of
APS-General." The description of the common stock and the description under
"Description of Common Stock-Certain Anti-Takeover Provisions of the Articles of
Incorporation" are subject to the provisions contained in the Fund's Articles of
Incorporation and By-Laws.

Shares of common stock have no preemptive, conversion, exchange or redemption
rights. Each such share has equal voting, dividend, distribution and liquidation
rights. The outstanding shares of common stock are fully paid and nonassessable.
Holders of common stock are entitled to one vote per share. The rights of the
holders of the common stock to elect directors and to vote on other matters are
subject to the voting rights of any outstanding APS, as discussed above under
"Description of APS-Voting Rights."

The Fund has established a dividend reinvestment plan under which all holders of
common stock whose shares of common stock are registered in their own names, or
in the name of UBS Financial Services Inc. or its nominee, have all dividends
and other distributions on their shares of common stock automatically reinvested
in additional shares of common stock, unless such common shareholders
affirmatively elect to receive cash. Holders of common stock may make such an
election, may terminate their participation, and may obtain additional
information regarding the plan, by writing to the transfer agent for the common
stock. Holders of common stock who hold their shares of such stock in the name
of a broker or nominee other than UBS Financial Services Inc. or its nominee
must contact such broker or nominee to determine whether, or how, they may
participate in the plan. Under the plan, shares of common stock are purchased in


                                      28


the open market for participants' accounts; the Fund does not issue any new
shares of common stock in connection with the plan. The number of shares for
participants with each dividend is determined on the basis of the average price
per share (including applicable brokerage commissions) obtained in the open
market. Experience under the dividend reinvestment plan may indicate that
changes are desirable; therefore, the Fund reserves the right to amend or
terminate the plan upon notice to common stockholders.

Under the rules of the NYSE applicable to listed companies, the Fund is normally
required to hold an annual meeting of shareholders. If the Fund is converted to
an open-end investment company or if for any other reason the Fund's common
stock is no longer listed on the NYSE (or any other national securities
exchange, the rules of which require annual meetings of Shareholders), the Fund
may decide not to hold annual meetings of Shareholders. See "Common Stock
Repurchases and Tender Offers; Conversion to Open-End Fund" in the SAI.

CERTAIN ANTI-TAKEOVER PROVISIONS OF THE ARTICLES OF INCORPORATION

The Fund currently has provisions in its Articles of Incorporation that have the
effect of limiting: (1) the ability of other entities or persons to acquire
control of the Fund; (2) the Fund's freedom to engage in certain transactions;
or (3) the ability of the Fund's directors or Shareholders to amend the Articles
of Incorporation.

These provisions of the Articles of Incorporation may be regarded as
"anti-takeover" provisions. Under Maryland law and the Articles of
Incorporation, the affirmative vote of the holders of at least a majority of the
votes entitled to be cast is required for the consolidation of the Fund with
another corporation, a merger of the Fund with or into another corporation
(except for certain mergers in which the Fund is the successor), a statutory
share exchange in which the Fund is not the successor, a Sale or transfer of all
or substantially all of the Fund's assets, the dissolution of the Fund and any
amendment to the Articles of Incorporation. In addition, the affirmative vote of
the holders of at least 66 2/3% (which is a greater percentage than that
required under Maryland law or the 1940 Act) of the outstanding shares of the
Fund's capital stock is required generally to authorize any of the following
transactions or to amend the provisions of the Articles of Incorporation
relating to such transactions:

     (1)  merger, consolidation or statutory share exchange of the Fund with or
          into any other corporation;

     (2)  issuance of any securities of the Fund to any person or entity for
          cash;

     (3)  sale, lease or exchange of all or any substantial part of the assets
          of the Fund to any entity or person (except assets having an aggregate
          market value of less than $1,000,000); or

     (4)  sale, lease or exchange to the Fund, in exchange for securities of the
          Fund, of any assets of any entity or person (except assets having an
          aggregate fair market value of less than $1,000,000)

if such corporation, entity or person is directly, or indirectly through
affiliates, the beneficial owner of more than 5% of the outstanding shares of
the Fund (a "Principal Shareholder"). The affirmative vote of at least 66 2/3%
of Shareholders would also be required for any amendment of the Articles of
Incorporation that would convert the Fund to an open-end investment company (by
making any class of the Fund's capital stock a "redeemable security," as that
term is defined in the 1940 Act). Such vote would not be required with respect
to any of the foregoing transactions, however, when, under certain conditions,
the Board approves the transaction, although a majority vote of the outstanding
shares of the Fund's capital stock may nevertheless be required in some cases.
The full text of these provisions is contained in the Articles of Incorporation
of the Fund, which are on file with the SEC. These voting rights are in addition
to the rights of the holders of any outstanding Preferred Stock to vote as a
single class on certain matters. See "Description of APS--Voting Rights."

The provisions of the Articles of Incorporation described above and the Fund's
right to repurchase or make a tender offer for its shares could have the effect
of depriving the holders of common stock of opportunities to sell their shares
at a premium over prevailing market prices by discouraging a third party from
seeking to obtain control of the Fund in a tender offer or similar transaction.
See "Common Stock Repurchases and Tender Offers; Conversion to Open-End Fund" in
the SAI. These provisions effectively render the accomplishment of a merger or
the assumption of control by a Principal Shareholder more difficult. They
provide the advantages of potentially (i) requiring persons seeking control of
the Fund to negotiate with its management regarding the price to be paid and
(ii) facilitating the continuity of the Fund's management, investment objective
and policies. The Board has considered the foregoing anti-takeover provisions
and concluded that they are in the best interests of the Fund and its
Shareholders.

                         TYPES OF MUNICIPAL OBLIGATIONS

             [PORTFOLIO MANAGER--VERIFY; SHOULD OTHERS BE INCLUDED?]

The Fund may invest in the following types of Municipal Obligations and in such
other types of Municipal Obligations as are described in the SAI or as become
available on the market from time to time.

MUNICIPAL BONDS. Municipal bonds are debt obligations issued to obtain funds for
various public purposes. 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 from another specific
source, such as the user of the facility being financed. Certain municipal bonds
are "moral obligation" issues, which normally are issued by special purpose
public 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.

INDUSTRIAL DEVELOPMENT BONDS AND PRIVATE ACTIVITY BONDS. Industrial development
bonds ("IDBs") and PABs are municipal bonds issued by or on behalf of public
authorities to finance various privately operated facilities, such as airports
or pollution control facilities. IDBs and PABs are generally revenue bonds and
thus are not payable from the unrestricted revenue 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. The Fund may invest more than 25% of
its assets in IDBs and PABs. IDBs issued after August 15, 1986 generally are
considered PABs, and to the extent the Fund invests in such PABs, stockholders
generally will be required to include a portion of their exempt-interest
dividends in calculating their liability for the AMT. See "Taxes."

MUNICIPAL LEASE OBLIGATIONS. Municipal lease obligations are Municipal
Obligations that may take the form of leases, installment purchase contracts or
conditional sales contracts, or certificates of participation with respect to
such contracts or leases. Municipal lease obligations are issued by state and
local governments and authorities to purchase land or various types of equipment
and facilities. 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 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.

The liquidity of municipal lease obligations varies. See "Other Investment
Practices." 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. In the case of a "non-appropriation" lease, the
Fund's ability to recover under the lease in the event of non-appropriation or
default will be limited solely to the repossession of the leased property,
without recourse to the general credit of the lessee, and disposition of the
property in the event of foreclosure might prove difficult. The Fund does not
intend to invest a significant portion of its assets in such "non-appropriation"
municipal lease obligations. There is no limitation on the Fund's ability to
invest in other municipal lease obligations.

ZERO COUPON OBLIGATIONS. The Fund may invest up to 10% of its total assets in
zero coupon Municipal Obligations. Such obligations include "pure zero"
obligations, which pay no interest for their entire life (either because they
bear no stated rate of interest or because their stated rate of interest is not
payable until maturity), and "zero/fixed" obligations, which pay no interest for
an initial period and thereafter pay interest currently. Zero coupon obligations
also include securities representing the principal-only components of Municipal
Obligations from which the interest components have been stripped and sold
separately by the holders of the underlying Municipal Obligations. Zero coupon
securities usually trade

                                       A-1


at a deep discount from their face or par value and will be subject to greater
fluctuations in market value in response to changing interest rates than
obligations of comparable maturities that make current distributions of
interest. While zero coupon Municipal Obligations will not contribute to the
cash available to the Fund for purposes of paying dividends to stockholders, UBS
Global AM believes that limited investments in such securities may facilitate
the Fund's ability to preserve capital while generating income through the
accrual of original issue discount. Zero coupon Municipal Obligations generally
are liquid, although such liquidity may be reduced from time to time due to
interest rate volatility and other factors.

Federal tax law requires the Fund to distribute at least 90% of its tax- exempt
income, plus its investment company taxable income, including non-cash income,
each year in order to qualify for pass-through federal income tax treatment as a
regulated investment company. Accordingly, although the Fund will receive no
payments on its zero coupon Municipal Obligations prior to their maturity or
disposition, it will have income attributable to such securities, and it might
be required, in order to maintain its desired tax treatment, to include in its
dividends the income attributable to its zero coupon securities. The Fund might
be required to liquidate portfolio securities at a time that it otherwise would
not have done so in order to make such dividends. The Fund will not be able to
purchase additional income- producing securities with cash used to make such
distributions, and as a result, its current income ultimately may be reduced.
See "Taxes" and "Investment Objectives and Policies--Other Investment Practices"
in this Prospectus and "Taxes" in the SAI.

FLOATING AND VARIABLE RATE OBLIGATIONS. The Fund also may purchase floating and
variable rate municipal notes and bonds, which frequently permit the holder to
demand payment of principal at any time, or at specified intervals, and permit
the issuer to prepay principal, plus accrued interest, at its discretion after a
specified notice period. The issuer's obligations under the demand feature of
such notes and bonds generally are secured by bank letters of credit or other
credit support arrangements. There may be no secondary market for variable and
floating rate obligations held by the Fund, although the Fund may be able to
obtain payment of principal at face value by exercising the demand feature of
the obligation.

MUNICIPAL DERIVATIVES. The Fund may invest in derivative securities that are
Municipal Obligations, or components thereof, that have been specially
structured to reflect investment characteristics ordinarily associated with
other securities or to have other special rights desired by investors.
Generally, such securities are designed to allow investors to take advantage of
expected interest rate trends or to hedge interest rate or other risks.
Detachable call options are sold by issuers of Municipal Obligations separately
from the Municipal Obligations to which the call options relate and permit the
purchasers of the call options to acquire the Municipal Obligations at the call
price(s) and call date(s). In the event that interest rates drop, the purchaser
could exercise the call option to acquire Municipal Obligations that yield
above-market rates. Municipal Obligations with embedded caps provide for
additional tax-free payments for a stated period (generally a period that is
shorter than the bond's maturity) above the fixed rate of interest payable on
the Municipal Obligations to the extent that the average level of a particular
index exceeds a specified base level. The Fund would use Municipal Obligations
with embedded caps in order to attempt to offset the risk of increases in
short-term interest rates while continuing to earn tax-exempt income.
Investments in municipal derivatives may be subject to the same risks as
floating rate Municipal Obligations, risks of adverse tax determinations or, in
the case of municipal derivatives used for hedging purposes, risks similar to
those for other hedging strategies. See "Hedging and Related Income Strategies"
in the SAI. The Fund will only invest in those municipal derivatives that UBS
Global AM believes will facilitate the Fund's ability to achieve its investment
objective.

OTHER MUNICIPAL OBLIGATIONS. The Fund also may invest in participations that
are issued by banks or other financial institutions and that represent
ownership interests in municipal bonds, IDBs or PABs, custodial receipts
representing ownership interests in future interest or principal payments on
such obligations, inverse floaters, put bonds and tender option bonds. The
Fund may purchase securities representing interests in underlying assets, but
structured to provide certain advantages not inherent in those assets (E.G.,
enhanced liquidity and yields linked to short-term interest rates). If those
securities behaved in a way that UBS Global AM did not anticipate, or if the
security structures encountered unexpected difficulties, the Fund could
suffer a loss.

                                       A-2


Like other sophisticated strategies, the Fund's use of structured notes may
not work as intended; for example, the change in value of the structured
notes may not match very closely the change in the value of bonds that the
structured notes were purchased to hedge.

                            MASTER PURCHASER'S LETTER

                      Relating to Securities Involving Rate
                    Settings Through Auctions or Remarketings

THE COMPANY
A REMARKETING AGENT
THE TRUST COMPANY
  OR AUCTION AGENT
A BROKER-DEALER
AGENT MEMBER
OTHER PERSONS

Dear Sirs:

     1.   This letter is designed to apply to publicly or privately offered debt
or equity securities ("Securities") of any issuer ("Company"), which are
described in any final prospectus or other offering materials relating to such
Securities, as the same may be amended or supplemented (collectively, with
respect to the particular Securities concerned, the "Prospectus") and which
involve periodic rate settings through auctions ("Auctions") or remarketing
procedures ("Remarketings"). This letter shall be for the benefit of any Company
and of any trust company, auction agent, paying agent (collectively, "trust
company"), remarketing agent, broker-dealer, agent member, securities depository
or other interested person in connection with any Securities and related
Auctions or Remarketings (it being understood that such persons may be required
to execute specified agreements and nothing herein shall alter such
requirements). The terminology used herein is intended to be general in its
application and not to exclude any Securities in respect of which (in the
Prospectus or otherwise) alternative terminology is used.

     2.   We may from time to time offer to purchase, purchase, offer to sell
and/or sell Securities of any company as described in the Prospectus relating
thereto. We agree that this letter shall apply to all such purchases, sales and
offers and to Securities owned by us. We understand that the dividend/interest
rate on Securities may be based from time to time on the results of Auctions or
Remarketings as set forth in the Prospectus.

     3.   We agree that any bid or sell order placed by us in an Auction shall
constitute an irrevocable offer (except as otherwise described in the
Prospectus) by us to purchase or sell the Securities subject to such bid or sell
order, or such lesser amount of Securities as we shall be required to sell or
purchase as a result of such Auction or Remarketing, at the applicable price,
all as set forth in the Prospectus, and that if we fail to place a bid or sell
order with respect to Securities owned by us with a broker-dealer on any Auction
or Remarketing date, or a broker-dealer to which we communicate a bid or sell
order fails to submit such bid or sell order to the trust company or remarketing
agent concerned, we shall be deemed to have placed a hold order with respect to
such Securities as described in the Prospectus, except as may otherwise be
described therein. We authorize any broker-dealer that submits a bid or sell
order as our agent in Actions or Remarketings to execute contracts for the sale
of Securities covered by such bid or sell order. We recognize that the payment
by such broker-dealer for Securities purchased on our behalf shall not relieve
us of any liability to such broker-dealer for payment for such Securities.

     4.   We understand that in a Remarketing, the dividend or interest rate or
rates on the Securities and the allocation of Securities tendered for sale among
dividend or interest periods of different lengths will be based from time to
time on the determinations of one or more remarketing agents, and we agree to be
conclusively bound by such determinations. We further agree to the payment of
different dividend or interest rates to different holders of Securities
depending on the length of the dividend or interest period elected by such
holders. We agree that any notice given by us to a remarketing agent (or to a
broker-dealer for transmission to a marketing agent) of our desire to tender
Securities in a Remarketing shall constitute an irrevocable (except to the
limited extent set forth in the Prospectus) offer by us to sell the Securities
specified in such notice, or such lesser number of Securities as we shall be
required to sell as a result of such Remarketing, in accordance with the terms
set forth in the Prospectus, and we authorize the remarketing agent to sell,
transfer or otherwise dispose of such Securities as set forth in the Prospectus.

                                        1


     5.   We agree that, during the applicable period as described in the
Prospectus, dispositions of Securities can be made only in the denominations set
forth in the Prospectus, and we will sell, transfer or otherwise dispose of any
Securities held by us from time to time only pursuant to a bid or sell order
placed in an Auction, in a Remarketing, to or through a broker-dealer or, when
permitted in the Prospectus, to a person that has signed and delivered to the
applicable trust company, auction agent or remarketing agent a letter
substantially in the form of this letter (or other applicable purchaser's
letter), provided that in the case of all transfers other than pursuant to
Auctions or Remarketings we or our broker-dealer or our agent member shall
advise such trust company, auction agent or remarketing agent of such transfer.
We understand that a restrictive legend will be placed on certificates
representing the Securities and stop-transfer instructions will be issued to the
transfer agent and/or registrar, all as set forth in the Prospectus.

     6.   We agree that, during the applicable period as described in the
Prospectus, ownership of Securities shall be represented by one or more global
certificates registered in the name of the applicable securities depository or
its nominee, that we will not be entitled to receive any certificate
representing the Securities, and that our ownership of any Securities will be
maintained in book entry form by the securities depository for the account of
our agent member, which in turn will maintain records of our beneficial
ownership. We authorize and instruct our agent member to disclose to the
applicable trust company, auction agent or remarketing agent such information
concerning our beneficial ownership of Securities as such trust company or
remarketing agent shall request.

     7.   We acknowledge that partial deliveries of Securities purchased in
Auctions or Remarketings may be made to us and such deliveries shall constitute
good delivery as set forth in the Prospectus.

     8.   This letter is not a commitment by us to purchase any Securities.

     9.   This letter supersedes any prior-dated version of this master
purchaser's letter, and supplements any prior- or post-dated purchaser's letter
specific to particular Securities, and this letter may only be revoked by a
signed writing delivered to the original recipients thereof.

     10.  The descriptions of Auction or Remarketing procedures set forth in
each applicable Prospectus are incorporated by reference herein and in case of
any conflict between this letter, any purchaser's letter specific to particular
Securities and any such description, such description shall control.

     11.  Any xerographic or other copy of this letter shall be deemed of equal
effect as a signed original.

     12.  Our agent member of The Depository Trust Company currently is       .

     13.  Our personnel authorized to place orders with broker-dealers for the
purpose set forth in the Prospectus in Auctions and Remarketings currently
is/are      , telephone number (  ).

     14.  Our taxpayer identification number is       .

     15.  In the case of each purchase, offer to purchase, offer to sell or sale
by us of Securities not registered under the Securities Act of 1933, as amended
(the "Act"), we represent and agree as follows:

          A.   We understand and expressly acknowledge that the Securities have
     not been and will not be registered under the Act and, accordingly, that
     the Securities may not be reoffered, resold or otherwise pledged,
     hypothecated or transferred unless an applicable exemption from the
     registration requirements of the Act is available.

          B.   We hereby confirm that any purchase of Securities made by us will
     be for our own account or for the account of one or more parties for which
     we are acting as trustee or agent with complete investment discretion and
     with authority to bind such parties, and not with a view to any public
     resale or distribution thereof. We and each other party for which we are
     acting which will acquire Securities will be "accredited investors" within
     the meaning of Regulation D under the Act with respect to the Securities to
     be purchased by us or such party, as the

                                        2


     case may be, will have previously invested in similar types of instruments
     and will be able and prepared to bear the economic risk of investing in and
     holding such Securities.

          C.   We acknowledge that prior to purchasing any Securities we shall
     have received a Prospectus (or private placement memorandum) with respect
     thereto and acknowledge that we will have had access to such financial and
     other information, and have been afforded the opportunity to ask such
     questions of representatives of the Company and receive answers thereto, as
     we deem necessary in connection with our decision to purchase Securities.

          D.   We recognize that the Company and broker-dealers will rely upon
     the truth and accuracy of the foregoing investment representations and
     agreements and we agree that each of our purchases of Securities now or in
     the future shall be deemed to constitute our concurrence in all of the
     foregoing which shall be binding on us and each party for which we are
     acting as set forth in Subparagraph B above.

                      INVESTMENT POLICIES AND RESTRICTIONS

     The following supplements the information contained in the Prospectus
concerning the Fund's investment policies and limitations.

APS RATING AGENCY GUIDELINES

     The Fund intends that, so long as the APS are outstanding, the composition
of its portfolio will reflect guidelines established by Moody's Investors
Service, Inc. ("Moody's") and Standard & Poor's, a division of The McGraw-Hill
Companies, Inc. ("S&P"), in connection with their respective ratings of the APS.
See Appendix B.

RATINGS AS INVESTMENT CRITERIA

     Moody's and S&P and the other nationally recognized statistical rating
organizations ("NRSROs" or "rating agencies") are private services that provide
ratings of the credit quality of debt, preferred stock and various other
securities, including Municipal Obligations. It should be emphasized that
ratings are general and are not absolute standards of quality. Consequently,
Municipal Obligations with the same maturity, interest rate and rating may have
different market prices. Also, rating agencies may fail to make timely changes
in credit ratings in response to subsequent events, so that an issuer's
financial condition may be better or worse than is indicated by its rating. A
description of Moody's and S&P's ratings is included in Appendix A to this SAI.

MUNICIPAL OBLIGATIONS

     Municipal Obligations are issued for various public purposes, including
construction of public facilities, such as airports, bridges, hospitals,
housing, mass transportation, schools, streets, and water and sewer works. Other
public purposes for which Municipal Obligations may be issued include
refinancing outstanding obligations and obtaining funds for general operating
expenses and for loans to other public institutions and facilities.

     Municipal Obligations, like other debt obligations, are subject to the risk
of non-payment. The ability of issuers of Municipal Obligations to make timely
payments of interest and principal may be adversely affected in general economic
downturns and as relative governmental cost burdens are allocated and
reallocated among federal, state and local governmental units. Such non-payment
would result in a reduction of income to the Fund, and could result in a
reduction in the value of the Municipal Obligation experiencing non-payment and
a potential decrease in the net asset value of the Fund. Issuers of Municipal
Obligations might seek protection under the bankruptcy laws. In the event of
bankruptcy of such an issuer, the Fund could experience delays and limitations
with respect to the collection of principal and interest on such Municipal
Obligations, and the Fund may not, in all circumstances, be able to collect all
principal and interest to which it is entitled. To enforce its rights in the
event of a default in the payment of interest or repayment of principal, or
both, the Fund may take possession of and manage the assets securing the
issuer's obligations on such securities, which may increase the Fund's operating
expenses and adversely affect the net asset value of the Fund. However, any
decline in the value of the Fund's assets will initially be borne entirely by
the Fund's holders of common stock.

     Under normal circumstances, the Fund does not invest 25% or more of its
total assets in any one industry. Governmental issuers of Municipal Obligations
are not considered part of any industry and, therefore, are not subject to this
limitation. Municipal Obligations backed only by the assets and revenues of
non-governmental entities, however, are considered to be issued by such
non-governmental entities and would be subject to this limitation. The Fund
reserves the right to invest more than 25% of its assets in industrial
development bonds or in issuers located in the same state. If the Fund were to
invest more than 25% of its total assets in issuers located in the same state,
it would be more susceptible to adverse economic, business or regulatory
conditions in that state.

     In addition to the more common varieties of Municipal Obligations described
in Appendix A to the prospectus, the Fund also is authorized to invest in the
following types of Municipal Obligations:

                                        2


     ASSET-BACKED SECURITIES. The Fund may invest in securities that are
comprised of Municipal Obligations that have been securitized through the use of
trusts or special purpose corporations or other entities. Payments or
distributions of principal and interest may be guaranteed up to a certain amount
and for a certain time period by a financial institution unaffiliated with the
issuer, or other credit enhancements may be present.

     MUNICIPAL LEASE OBLIGATIONS. Municipal bonds include municipal lease
obligations, such as leases, installment purchase contracts and conditional
sales contracts, and certificates of participation therein. Municipal lease
obligations are issued by state and local governments and authorities to
purchase land or various types of equipment or facilities and may be subject to
annual budget appropriations. The Fund generally invests in municipal lease
obligations through certificates of participation. Although municipal lease
obligations do not constitute general obligations of the municipality for which
the municipality's taxing power is pledged, they ordinarily are backed by the
municipality's covenant to budget for, appropriate and make the payments due
under the lease obligation. The leases underlying certain municipal lease
obligations, however, provide that lease payments are subject to partial or full
abatement if, because of material damage or destruction of the leased property,
there is substantial interference with the lessee's use or occupancy of such
property. This "abatement risk" may be reduced by the existence of insurance
covering the leased property, the maintenance by the lessee of reserve funds or
the provision of credit enhancements such as letters of credit. Certain
municipal lease obligations contain "non-appropriation" clauses which provide
that the municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for 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, the 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.

     MORTGAGE SUBSIDY BONDS. The Fund also may purchase mortgage subsidy bonds
that are issued to subsidize mortgages on single family homes and "moral
obligation" bonds that are normally issued by special purpose public
authorities. In some cases the repayment of these 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).

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

     A participation interest gives the Fund an undivided interest in a
municipal bond owned by a financial institution. The Fund has the right to sell
the instruments back to the financial institution. To the extent that payment of
an obligation is backed by a letter of credit, guarantee or liquidity support
arrangement from a financial institution, that payment may be subject to the
financial institution's ability to satisfy that commitment. UBS Global AM will
monitor the pricing, quality and liquidity of the participation interests held
by the Fund, and the credit standing of financial institutions issuing letters
of credit or guarantees supporting those participation interests on the basis of
published financial information, reports of rating services and/or financial
institution analytical services.

     CUSTODIAL RECEIPTS. The Fund may acquire custodial receipts or certificates
underwritten by securities dealers or banks that evidence ownership of future
interest payments, principal payments or both on certain Municipal Obligations.
The underwriter of these certificates or receipts typically purchases Municipal
Obligations and deposits the obligations in an irrevocable trust or custodial
account with a custodial bank, which then issues receipts or certificates that
evidence ownership of the periodic unmatured coupon payments and the final
principal payment on the obligations. Custodial receipts evidencing specific
coupon or principal payments

                                        3


have the same economic attributes as zero coupon Municipal Obligations described
herein. Although under the terms of a custodial receipt the Fund would be
typically authorized to assert its rights directly against the issuer of the
underlying obligation, the Fund could be required to assert through the
custodian bank those rights that may exist against the underlying issuer. Thus,
in the event the underlying issuer fails to pay principal or interest when due,
the Fund may be subject to delays, expenses and risks that are greater than
those that would have been involved if the Fund had purchased a direct
obligation of the issuer. In addition, in the event that the trust or custodial
account in which the underlying security has been deposited is determined to be
an association taxable as a corporation, instead of a non-taxable entity, the
yield on the underlying security would be reduced in recognition of any taxes
paid.

     INVERSE FLOATERS. The 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 rate that is set periodically through an auction process or other
method, and a residual component, 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 residual components is
generally determined by subtracting the interest rate paid to the holders of
auction components from a fixed amount, the interest rate paid or residual
component holders will decrease as the auction component's rate increases and
increase as the auction component's rate decreases. Moreover, the extent of the
increases and decreases in market value of residual components 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.

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

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

     TENDER OPTION BONDS. Tender option bonds are long-term Municipal
Obligations 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 order to cause the
bonds to have a market value that approximates their par value. The tender
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.


WHEN-ISSUED AND DELAYED DELIVERY SECURITIES

     As stated in the Prospectus, the Fund may purchase securities on a
"when-issued' basis or may purchase or sell securities for delayed delivery,
I.E., for issuance or delivery to or by the Fund later than the normal
settlement date at a stated price and yield. The Fund generally would not pay
for such securities or start earning interest on them until they are received.
However, when the Fund undertakes a when-issued or delayed delivery obligation,
it immediately assumes the risks of ownership, including the risks of price
fluctuation. Failure of the issuer to deliver a security purchased by a fund on
a when-issued or delayed delivery basis may result in a fund's incurring a loss
or missing an opportunity to make an alternative investment.

                                        4


     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. A fund's when-issued and delayed delivery purchase
commitments could cause its net asset value per share to be more volatile. The
Fund may sell the right to acquire the security prior to delivery if UBS Global
AM deems it advantageous to do so, which may result in a gain or loss to the
fund. When the Fund commits to purchase securities on a when-issued or delayed
delivery basis, its custodian will set aside in a segregated account cash or
liquid securities, marked to market daily, with a market value equal to the
amount of the commitment. If necessary, additional assets will be placed in the
account daily so that the value of the account will equal or exceed the amount
of the Fund's purchase commitment.

STAND-BY COMMITMENTS

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

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

LENDING OF PORTFOLIO SECURITIES

                                        5


     The Fund is authorized to lend its portfolio securities to broker-dealers
or institutional investors that UBS Global AM deems qualified. Lending
securities enables the Fund to earn additional income, but could result in a
loss or delay in recovering these securities. The borrower of the Fund's
portfolio securities must maintain acceptable collateral with the Fund's
custodian in an amount, marked to market daily, at least equal to the market
value of the securities loaned, plus accrued interest and dividends. Acceptable
collateral is limited to cash, US government securities and irrevocable letters
of credit that meet certain guidelines established by UBS Global AM. The Fund
may reinvest any cash collateral in money market investments or other short-term
liquid investments, including other investment companies. The Fund also may
reinvest cash collateral in private investment vehicles similar to money market
funds, including one managed by UBS Global AM. In determining whether to lend
securities to a particular broker-dealer or institutional investor, UBS Global
AM will consider, and during the period of the loan will monitor, all relevant
facts and circumstances, including the creditworthiness of the borrower. The
Fund will retain authority to terminate any of its loans at any time. The Fund
may pay fees in connection with a loan and may pay the borrower or placing
broker a negotiated portion of the interest earned on the reinvestment of cash
held as collateral. The Fund will receive amounts equivalent to any interest,
dividends or other distributions on the securities loaned. The Fund will regain
record ownership of loaned securities to exercise beneficial rights, such as
voting and subscription rights, when regaining such rights is considered to be
in the Fund's interest. Pursuant to procedures adopted by the Board governing
the Fund's securities lending program, UBS Securities LLC ("UBS Securities"),
another wholly owned indirect subsidiary of UBS AG and the principal
underwriter of this offering, has been retained to serve as lending agent for
the Fund. The Board also has authorized the payment of fees (including fees
calculated as a percentage of invested cash collateral) to UBS Securities for
these services. The board periodically reviews all portfolio securities loan
transactions for which UBS Securities acted as lending agent. UBS Securities
and other affiliated broker-dealers have also been approved as borrowers under
the Fund's securities lending program.

ILLIQUID SECURITIES

     As noted in the Prospectus, the Fund may invest up to 20% of its total
assets in illiquid securities. The term "illiquid securities" means securities
that cannot be disposed of within seven days in the ordinary course of business
at approximately the amount at which the Fund has valued the securities and
includes, among other things, repurchase agreements maturing in more than seven
days and restricted securities other than those UBS Global AM has determined are
liquid pursuant to guidelines established by the Board. The Fund may not be able
to readily liquidate its investments in illiquid securities and may have to sell
other investments if necessary to raise cash to meet its obligations. The lack
of a liquid secondary market for illiquid securities may make it more difficult
for the Fund to assign a value to those securities for purposes of valuing its
portfolio and calculating its net asset value.

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

     Not all restricted securities are illiquid. A large institutional market
has developed for many US and foreign securities that are not registered under
the Securities Act. Institutional investors generally will not seek to sell
these instruments to the general public but instead will often depend either on
an efficient institutional market in which such unregistered securities can be
readily resold or on an issuer's ability to honor a demand for repayment.
Therefore, the fact that there are contractual or legal restrictions on resale
to the general public or certain institutions is not dispositive of the
liquidity of such investments.

     Institutional markets for restricted securities also have developed as a
result of Rule 144A under the Securities Act, which establishes a "safe harbor"
from the registration requirements of that Act for resales of certain securities
to qualified institutional buyers. These markets include automated systems for
the trading, clearance and settlement of unregistered securities of domestic and
foreign issuers, such as the PORTAL System sponsored by the National Association
of Securities Dealers, Inc. An insufficient number of qualified

                                        6


institutional buyers interested in purchasing Rule 144A-eligible restricted
securities held by the Fund, however, could affect adversely the marketability
of such portfolio securities, and the Fund might be unable to dispose of them
promptly or at favorable prices.

     The Board has delegated the function of making day-to-day determinations of
liquidity to UBS Global AM, pursuant to guidelines approved by the Board. UBS
Global AM takes into account a number of factors in reaching liquidity
decisions, which may include (1) the frequency of trades for the security, (2)
the number of dealers that make quotes for the security, (3) the nature of the
security and how trading is effected (E.G., the time needed to sell the
security, how bids are solicited and the mechanics of transfer) and (4) the
existence of demand features or similar liquidity enhancements. UBS Global AM
monitors the liquidity of restricted securities in the Fund's portfolio and
reports periodically on such decisions to the Board. UBS Global AM also monitors
the Fund's overall holdings of illiquid securities. If the Fund's holdings of
illiquid securities exceed its limitation on investments in illiquid securities
for any reason (such as a particular security becoming illiquid, or changes in
the relative market values of liquid and illiquid portfolio securities), UBS
Global AM will consider what action would be in the best interests of the Fund
and its shareholders. Such action may include engaging in an orderly disposition
of securities to reduce the Fund's holdings of illiquid securities. However, the
Fund is not required to dispose of illiquid securities under these
circumstances.

     In making determinations as to the liquidity of municipal lease
obligations, UBS Global AM 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, UBS Global
AM 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 the
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.

REPURCHASE AGREEMENTS

     Repurchase agreements are transactions in which the Fund purchases
securities or other obligations from a bank or securities dealer (or its
affiliate) and simultaneously commits to resell them to the counterparty at an
agreed-upon date or upon demand and at a price reflecting a market rate of
interest unrelated to the coupon rate or maturity of the purchased obligations.
Securities or other obligations subject to repurchase agreements may have
maturities in excess of 13 months. The Fund maintains custody of the underlying
obligations prior to their repurchase, either through its regular custodian or
through a special "tri-party" custodian or sub-custodian that maintains a
separate account for both the Fund and its counterparty. Thus, the obligation of
the counterparty to pay the repurchase price on the date agreed to or upon
demand is, in effect, secured by such obligations.

     Repurchase agreements carry certain risks not associated with direct
investments in securities, including a possible decline in the market value of
the underlying obligations. If their value becomes less than the repurchase
price, plus any agreed-upon additional amount, the counterparty must provide
additional collateral so that at all times the collateral is at least equal to
the repurchase price plus any agreed-upon additional amount. The difference
between the total amount to be received upon repurchase of the obligations and
the price that was paid by the Fund upon acquisition is accrued as interest and
included in its net investment income. Repurchase agreements involving
obligations other than US government securities (such as commercial paper,
corporate bonds and mortgage loans) may be subject to special risks and may not
have the benefit of certain protections in the event of the counterparty's
insolvency. If the seller or guarantor becomes insolvent, the Fund may suffer
delays, costs and possible losses in connection with the disposition of
collateral. The Fund intends to enter into repurchase agreements only in
transactions with counterparties believed by UBS Global AM to present minimum
credit risks.

                                        7


REVERSE REPURCHASE AGREEMENTS

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

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

     Reverse repurchase agreements will be treated as borrowings for purposes of
calculating the Fund's borrowing limitation. See "Investment Limitations."

COUNTERPARTIES

     The Fund may be exposed to the risk of financial failure or insolvency of
another party. To help lessen those risks, UBS Global AM, subject to the
supervision of the Board, monitors and evaluates the creditworthiness of the
parties with which the Fund does business.

                             INVESTMENT LIMITATIONS

     The following fundamental investment limitations cannot be changed without
the affirmative vote of the lesser of (a) more than 50% of the outstanding
shares of the Fund or (b) 67% or more of such shares present at a stockholders'
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 a change in values of portfolio securities or the amount of total
assets will not be considered a violation of any of the following limitations or
of any of the Fund's investment policies.

     The Fund will not:

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

     The following interpretation applies to, but is not a part of, this
fundamental limitation: Each state (including the District of Columbia and
Puerto Rico), territory and possession of the United States, 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
Industrial Development Bond or Private Activity Bond, if that bond is backed
only by the assets and revenues of the non-governmental user, then that
non-governmental user would be deemed to be the sole issuer. However, if the
creating government or another entity guarantees a security, then to the extent
that the value of all securities issued or guaranteed by that government or
entity and owned by the Fund exceeds 10% of the Fund's total assets, the
guarantee would be considered a separate security and would be treated as issued
by that government or entity.

     (2) purchase any security if, as a result of that purchase, 25% or more of
the Fund's total assets would be invested in securities of issuers having their
principal business activities in the same industry, except that this

                                        8


limitation does not apply to securities issued or guaranteed by the US
government, its agencies or instrumentalities or to municipal securities.

     (3) issue senior securities (including borrowing money from banks and other
entities and through reverse repurchase agreements), except (a) the Fund may
borrow in an amount not in excess of 33 1/3% of total assets (including the
amount of senior securities issued, but reduced by any liabilities and
indebtedness not constituting senior securities), (b) the Fund may issue
preferred stock having a liquidation preference in an amount which, combined
with the amount of any liabilities or indebtedness constituting senior
securities, is not in excess of 50% of its total assets (computed as provided in
clause (a) above) and (c) the Fund may borrow up to an additional 5% of its
total assets (not including the amount borrowed) for temporary or emergency
purposes.

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

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

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

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

     The following investment restrictions are not fundamental and may be
changed by the Fund's Board without shareholder approval.

     The Fund will not:

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

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

                      HEDGING AND RELATED INCOME STRATEGIES

     As discussed in the Prospectus, UBS Global AM may use a variety of
financial instruments ("Hedging Instruments"), including certain options,
futures contracts (sometimes referred to as "futures"), options on futures
contracts and interest rate protection transactions, to attempt to hedge the
Fund's portfolio and may use options to attempt to enhance the Fund's income.
Because the Fund intends to use these instruments for hedging purposes, the Fund
may enter into (1) options and futures transactions that approximate (but do not
exceed) the full value of its portfolio and (2) interest rate protection
transactions (i.e., interest rate swaps and interest rate caps, collars and
floors) with notional amounts that approximate (but do not exceed) the
liquidation preference amount of preferred shares outstanding. Any income
realized from the use of options and futures would be taxable to shareholders.
See Appendix E (Hedging and Related Income Strategies).

     For as long as the APS are rated by Moody's, the Fund may engage in
transactions in options on securities, futures contracts based on the Municipal
Index or Treasury Bonds and options on such futures contracts (collectively
"Moody's Hedging Transactions") only when consistent with the provisions set
forth in Appendix B, unless it receives written confirmation from Moody's that
engaging in such transactions will not

                                        9


impair the ratings then assigned to the APS by Moody's. For as long as the APS
are rated by S&P, the Fund will not buy or sell futures contracts or options
thereon or write put options or call options on portfolio securities or enter
into interest rate caps, collars or floors unless it receives written
confirmation from S&P that engaging in such transactions will not impair the
ratings then assigned to the APS by S&P, except that the Fund may buy and sell
futures contracts based on the Municipal Index or Treasury Bonds, may purchase
put and call options on such contracts and may write covered call options and
secured put options on portfolio securities (collectively "S&P Hedging
Transactions") subject to the limitations described in Appendix B.

     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 the Fund's portfolio. Thus, in a short hedge, the Fund takes
a position in a Hedging Instrument the price of which is expected to move in the
opposite direction of the price of the investment being hedged. For example, the
Fund might purchase a put option on a security to hedge against a potential
decline in the value of that security. If the price of the security declined
below the exercise price of the put, the Fund could exercise the put and thus
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 the Fund intends to acquire. Thus, in a
long hedge the Fund takes a position in a Hedging Instrument the price of which
is expected to move in the same direction as the price of the prospective
investment being hedged. For example, the Fund might purchase a call option on a
security it intends to purchase in order to hedge against an increase in the
cost of the security. If the price of the security increased above the exercise
price of the call, the Fund could exercise the call and thus limit its
acquisition cost to the exercise price plus the premium paid and transaction
costs. Alternatively, the Fund might be able to offset the price increase by
closing out an appreciated call option and realizing a gain.

     Hedging Instruments on securities generally are used to hedge against price
movements in one or more particular securities positions that the Fund owns or
intends to acquire. 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
SEC, the several options and futures exchanges upon which they are traded and
the Commodity Futures Trading Commission ("CFTC"). In addition, the Fund's
ability to use Hedging Instruments will be limited by tax considerations. See
"Taxation."

     In addition to the products, strategies and risks described below, UBS
Global AM expects additional opportunities to develop in connection with
options, futures contracts and other hedging techniques. These new opportunities
may become available as UBS Global AM develops new techniques, as regulatory
authorities broaden the range of permitted transactions and as new options,
futures contracts or other techniques are developed. UBS Global AM may utilize
these opportunities to the extent that they are consistent with the Fund's
investment objective and permitted by the Fund's investment limitations and
applicable regulatory authorities.

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 UBS Global AM's
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 UBS Global AM 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

                                       10


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 indexes 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 the Fund entered into a
short hedge because UBS Global AM 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, the 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 the 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 the Fund's ability
to sell a portfolio security or make an investment at a time when it would
otherwise be favorable to do so, or require that the Fund sell a portfolio
security at a disadvantageous time. The Fund's ability to close out a position
in a 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 the Fund to an obligation to another party. The Fund will not enter into
any such transactions unless it owns either (1) an offsetting ("covered")
position in securities or other options or futures contracts or (2) cash or
liquid securities, with a value sufficient at all times to cover its potential
obligations to the extent not covered as provided in (1) above. The Fund will
comply with SEC guidelines regarding cover for hedging transactions and will, if
the guidelines so require, set aside cash or liquid securities, marked to market
daily, 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
the Fund's assets to cover or segregated accounts could impede portfolio
management or the Fund's ability to meet redemptions of APS or other
obligations.

OPTIONS

     The Fund may purchase put and call options, and write (sell) covered call
options and covered put 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 the 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 on 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

                                       11


conditions. Options normally have expiration dates of up to nine months. Options
that expire unexercised have no value.

     The Fund may effectively terminate its right or obligation under an option
by entering into a closing transaction. For example, the Fund may terminate its
obligation under a call option that it had written by purchasing an identical
call option; this is known as a closing purchase transaction. Conversely, the
Fund may terminate a position in a put or call option it had purchased by
writing an identical put or call option; this is known as a closing sale
transaction. Closing transactions permit the Fund to realize profits or limit
losses on an option position prior to its exercise or expiration.

     The Fund may purchase or write both exchange-traded and OTC options.
However, exchange-traded or liquid OTC options on Municipal Obligations are not
currently available. 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 the loss of
any expected benefit of the transaction.

     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.

     The Fund's ability to establish and close out positions in exchange-listed
options depends on the existence of a liquid market. The Fund intends to
purchase or write only those exchange-traded options for which there appears to
be a liquid secondary market. However, there can be no assurance that such a
market will exist at any particular time. Closing transactions can be made for
OTC options only by negotiating directly with the contra party, or by a
transaction in the secondary market if any such market exists. Although the 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 the Fund were unable to effect a closing transaction for an option it
had purchased, it would have to exercise the option to realize any profit. The
inability to enter into a closing purchase transaction for a covered call option
written by the Fund could cause material losses because the Fund would be unable
to sell the investment used as cover for the written option until the option
expires or is exercised.

     In the event that options on indexes of municipal and non-municipal debt
securities become available, the Fund may purchase and write put and call
options on such indexes 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 market (or market sectors) rather than
anticipated increases or decreases in the value of a particular security.

FUTURES

     The Fund may purchase and sell municipal bond index futures, other interest
rate futures and options thereon. 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, using a strategy similar
to that used for writing covered call options on securities or indexes.
Similarly, writing covered put options on futures contracts can serve as a
limited long hedge.

     Futures strategies also can be used to manage the average duration of the
Fund's portfolio. If UBS Global AM wishes to shorten the average duration of the
Fund's portfolio, the Fund may sell a futures contract or a call option thereon,
or purchase a put option on that futures contract. If UBS Global AM wishes to
lengthen the average duration of the Fund's portfolio, the Fund may buy a
futures contract or a call option thereon, or sell a put option thereon.

                                       12


     No price is paid upon entering into a futures contract. Instead, at the
inception of a futures contract the Fund is required to deposit in a
segregated account with its custodian, in the name of the futures broker
through whom the transaction was effected, "initial margin" consisting of
cash, obligations of the United States or obligations that are fully
guaranteed as to principal and interest by the United States, in an amount
generally equal to 10% or less of the contract value. Margin must also be
deposited when writing a call option on a futures contract, in accordance
with applicable exchange rules. Unlike margin in securities transactions,
initial margin on futures contracts does not represent a borrowing, but
rather is in the nature of a performance bond or good-faith deposit that is
returned to the Fund at the termination of the transaction if all contractual
obligations have been satisfied. Under certain circumstances, such as periods
of high volatility, the Fund may be required by an exchange or counterparty
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 with respect to an open
futures position. When the Fund purchases an option on a future, the premium
paid plus transaction costs is all that is at risk. In contrast, when the Fund
purchases or sells a futures contract or writes a call option thereon, it is
subject to daily variation margin calls that could be substantial in the event
of adverse price movements. If the Fund has insufficient cash to meet daily
variation margin requirements, it might need to sell securities at a time when
such sales are disadvantageous.

     Holders and writers of futures positions and options on futures can enter
into offsetting closing transactions, similar to closing transactions on
options, by selling or purchasing, respectively, an instrument identical to the
instrument held or written. Positions in futures and options on futures may be
closed only on an exchange or board of trade that provides a secondary market.
The Fund intends to enter into futures transactions only on exchanges or boards
of trade where there appears to be a liquid secondary market. However, there can
be no assurance that such a market will exist for a particular contract at a
particular time. Secondary markets for options on futures are currently in the
development stage, and the Fund will not trade options on futures on any
exchange or board of trade unless, in UBS Global AM's opinion, the markets for
such options have developed sufficiently that the liquidity risks for such
options are not greater than the corresponding risks for futures.

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

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

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

                                       13


GUIDELINE FOR FUTURES AND RELATED OPTIONS

     To the extent that the Fund enters into futures contracts and options on
futures positions that are not for BONA FIDE hedging purposes (as defined by the
CFTC), the aggregate initial margin and premiums on these positions (excluding
the amount by which options are "in-the-money") may not exceed 5% of the Fund's
net assets. This guideline may be modified by the Fund's board of directors
without a stockholder vote. Adoption of this guideline cannot be guaranteed to
limit the percentage of the Fund's assets at risk to 5%.

     The Fund may use the following Hedging Instruments:

     OPTIONS ON DEBT SECURITIES. A call option is a 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,
or upon the expiration, of the option. The writer of the call option, who
receives the premium, has the obligation, upon exercise of the option, 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 or upon expiration. The writer of the put option, who receives the premium,
has the obligation, upon exercise, 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.

                                       14


     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.

     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.

     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 put.

     INTEREST RATE PROTECTION TRANSACTIONS. The Fund may enter into interest
rate protection transactions, including interest rate swaps and interest rate
caps, collars and floors. Interest rate swap transactions involve an agreement
between two parties to exchange payments that are based, for example, on
variable and fixed rates of interest and that are calculated on the basis of a
specified amount of principal (the "notional principal amount") for a specified
period of time. Interest rate cap and floor transactions involve an agreement
between two parties in which the first party agrees to make payments to the
counterparty when a designated market interest rate goes above (in the case of a
cap) or below (in the case of a floor) a designated level on predetermined dates
or during a specified time period. Interest rate collar transactions involve an
agreement between two parties in which payments are made when a designated
market interest rate either goes above a designated level or goes below a
designated floor level on predetermined dates or during a specified time period.

     The Fund would enter into interest rate protection transactions to preserve
a return or spread on a particular investment or portion of its portfolio, to
protect against any increase in the price of securities the Fund anticipates
purchasing at a later date or to effectively fix the rate of interest that it
pays on one or more borrowings or series of borrowings. The Fund would use these
transactions as a hedge and not as a speculative investment. Interest rate
protection transactions are subject to risks comparable to those described above
with respect to other hedging strategies.

     The Fund may enter into interest rate swaps, caps, collars and floors on
either an asset-based or liability-based basis, depending on whether it is
hedging its assets or its liabilities, and will usually enter into interest rate
swaps on a net basis, I.E., the two payment streams are netted out, with the
Fund receiving or paying, as the case may be, only the net amount of the two
payments. Inasmuch as these interest rate protection transactions are entered
into for good faith hedging purposes, and inasmuch as segregated accounts will
be established with respect to such transactions, UBS Global AM and the Fund
believe such obligations do not constitute senior securities and, accordingly,
will not treat them as being subject to its borrowing restrictions. The net
amount of the excess, if any, of the Fund's obligations over its entitlements
with respect to each interest rate swap will be accrued on a daily basis and an
amount of cash or liquid securities, marked to market daily, having an aggregate
net asset value at least equal to the accrued excess will be maintained in a
segregated account by a custodian that satisfies the requirements of the
Investment Company Act of 1940 ("1940 Act"). The Fund also will establish and
maintain such segregated accounts with respect to its total obligations under
any interest rate swaps that are

                                       15


not entered into on a net basis and with respect to any interest rate caps,
collars and floors that are written by the Fund.

     The Fund will enter into interest rate protection transactions only with
banks and recognized securities dealers or their affiliates believed by UBS
Global AM to present minimal credit risks in accordance with guidelines
established by the Fund's board of directors. If there is a default by the other
party to such a transaction, the Fund will have to rely on its contractual
remedies (which may be limited by bankruptcy, insolvency or similar laws)
pursuant to the agreements related to the transaction.

     The swap market has grown substantially in recent years with a large number
of banks and investment banking firms acting both as principals and as agents
utilizing standardized swap documentation. Caps, collars and floors are more
recent innovations for which documentation is less standardized, and
accordingly, they are less liquid than swaps.

     ORGANIZATION OF THE FUND; DIRECTORS AND OFFICERS; PRINCIPAL HOLDERS AND
                       MANAGEMENT OWNERSHIP OF SECURITIES

     The Fund was incorporated under the laws of the state of Maryland on August
6, 1992. The overall management of the business and affairs of the Fund is
vested in its Board. The Board approves all significant agreements between the
Fund and persons or companies furnishing services to it, including the Fund's
agreements with its investment advisor and administrator, custodian and transfer
and dividend disbursing agent and registrar. The day-to-day operations of the
Fund are delegated to the Fund's officers and to UBS Global AM, subject to the
investment objective and policies of the Fund and to general supervision by the
Fund's board of directors.

     Each of the Fund's directors serves an indefinite term of office. Each
director who has attained the age of seventy-two (72) years will be subject to
retirement on the last day of the month in which he or she attains such age. The
tables below show, for each director (sometimes referred to as a "board member")
and executive officer, his or her name, address and age, the position held with
the Fund, the length of time served as a director or officer of the Fund, the
director's or officer's principal occupations during the last five years, the
number of portfolios in the UBS fund complex overseen by the director or for
which such person served as an officer, and other directorships held by such
director.

planning or conducting the Fund's audit or determining whether the Fund's
financial statements are complete and accurate and are in accordance with
accounting principles generally accepted in the United States. Absent actual
knowledge to the contrary, Audit and Contract Review Committee members are
entitled to rely on the accuracy of the information they receive from persons
within and outside the Fund. The Audit and Contract Review Committee also
reviews the performance by certain service providers of their contracts and
arrangements with the Fund and recommends to the board concerning the initial
approval and/or continuation of each of the proposed contracts and arrangements
and the reasonableness and appropriateness of the compensation paid by the
Funds. The Audit and Contract Review Committee currently normally meets in
conjunction with regular board meetings, or more frequently as called by its
chairperson. During the Fund's fiscal year ended September 30, 2003, the Audit
and Contract Review Committee held 5 meetings.

     The Nominating Committee is responsible for, among other things: selecting,
evaluating and recommending to the board candidates to be nominated as
additional Independent Directors of the Fund and reviewing the compensation
arrangements for each of the directors. The Nominating Committee did not meet
during the fiscal year ended September 30, 2003. The Nominating Committee will
consider nominees recommended by shareholders if a vacancy occurs among the
Independent Directors. In order to recommend a nominee, a shareholder should
send a letter to the chairperson of the Nominating Committee, Mr. Meyer
Feldberg, care of the Secretary of the Fund at 51 West 52nd Street, New York,
New York 10019-6114 and indicate on the envelope "Nominating Committee." The
shareholder's letter should state the nominee's name and should include the
nominee's RESUME or CURRICULUM VITAE.

COMPENSATION

     Each Independent Director receives, in the aggregate from UBS Global AM
Funds, an annual retainer of $50,000, and a $10,000 fee for each regular board
meeting (and each in-person special board meeting) actually attended. Each such
board member is also entitled to a $2,000 fee for each special telephone meeting
attended. The chairperson of the Audit and Contract Review Committee receives
annually $12,500. The chairperson of the Nominating Committee receives annually
$5,000. The foregoing fees will be allocated among all such funds (or each
relevant fund in the case of a special meeting) pro rata based on the fund's
relative net assets at the end of the calendar quarter preceding the date of
payment. No officer, director or employee of UBS Global AM or one of its
affiliates currently receives any compensation from the funds for acting as a
board member or officer. All board members are reimbursed for expenses incurred
in attending meetings.

     The table below includes certain information relating to the compensation
of the current board members and the compensation of those board members from
all Funds for which UBS Global AM or an affiliate served as an investment
advisor, sub-advisor or manager during the periods indicated.

               INVESTMENT ADVISORY AND ADMINISTRATION ARRANGEMENTS

     UBS Global AM is the Fund's investment adviser and administrator pursuant
to a contract dated October 15, 1992 with the Fund ("Advisory and Administration
Contract"). Pursuant to the Advisory and Administration Contract, UBS Global AM
provides a continuous investment program for the Fund and makes investment
decisions and places orders to buy, sell or hold particular securities. As
administrator, UBS Global AM supervises all matters relating to the operation of
the Fund and obtains for it corporate, administrative and clerical personnel,
office space, equipment and services, including arranging for the periodic
preparation, updating, filing and dissemination of proxy materials, tax returns
and reports to the Fund's Board, shareholders and regulatory authorities. Under
the Advisory and Administration Contract, the Fund pays UBS Global AM a fee,
computed weekly and paid monthly, at the annual rate of 0.90% of the Fund's
average weekly net assets. UBS Global AM has agreed to waive 0.20%, of the
advisory fee, so that the Fund's effective advisory fee is 0.70% of average
weekly net assets. This waiver will continue indefinitely unless the Board
agrees to any change. During the fiscal years indicated, the Fund paid (or
accrued) the following investment advisory and administration fees:

     In addition to the payments to UBS Global AM under the Advisory and
Administration Contract described above, the Fund pays certain other costs
including: (1) the costs (including any brokerage commissions) of securities
purchased or sold by the Fund and any losses incurred in connection therewith;
(2) expenses incurred on behalf of the Fund by UBS Global AM; (3) organizational
expenses of the Fund, whether or not advanced by UBS Global AM; (4) filing fees
and expenses relating to the registration and qualification of the common stock
under federal and state securities laws; (5) fees and salaries payable to
directors who are not interested persons of the Fund or UBS Global AM; (6) all
expenses incurred in connection with the directors' 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 any other
insurance or fidelity bonds; (9) any costs, expenses or losses arising out of a
liability of or claims 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 directors; (11) charges of
custodians, transfer agents and other agents; (12) costs of preparing share
certificates; (13) expenses of printing and distributing reports to
shareholders; (14) any extraordinary expenses (including fees and disbursements
of counsel) incurred by the Fund; (15) fees, voluntary assessments and other
expenses

                                       24


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 costs of investment company
literature and other publications provided to directors and officers; (18) costs
of mailing, stationery and communications equipment; (19) interest charges on
borrowings; (20) fees and expenses of listing and maintaining any listing of the
Fund's shares on the New York Stock Exchange, Inc. ("NYSE") or any other
national securities exchange; and (21) costs and expenses (including rating
agency fees) associated with the issuance of any Preferred Stock.

     At the Fund's board meeting on July 23, 2003, the board members considered
and approved the continuance of the Fund's Advisory and Administration Contract
with UBS Global AM. Prior to that meeting, the Board's Audit and Contract Review
Committee (comprised of the independent board members) also had met to review
and discuss the investment advisory and administration services provided to the
Fund over the course of the year by UBS Global AM. In considering the
continuance of the Advisory and Administration Contract, the Audit and Contract
Review Committee analyzed the nature, quality and scope of such services, the
revenues received and expenses incurred (actual and projected) by UBS Global AM
in performing the services required under the Advisory and Administration
Contract, and the cost-allocation methods used in calculating such expenses. The
Audit and Contract Review Committee also reviewed UBS Global AM's profitability
in managing the Fund; the current fees paid by the Fund in light of fees paid to
other advisors by comparable funds; fees paid to UBS Global AM by other funds it
advises; and the ability of UBS Global AM to continue to perform the services
contemplated under the Advisory and Administration Contract.

     The Audit and Contract Review Committee also evaluated the performance of
the Fund in comparison to funds with similar objectives and policies, the
relevant investment advisory personnel, compliance with its investment
restrictions, tax and reporting requirements and procedures of UBS Global AM
with respect to possible conflicts of interest, including UBS Global AM's code
of ethics; UBS Global AM's trade allocation procedures for its various
investment advisory clients and UBS Global AM's best execution procedures. Based
on all of the above, as well as other factors and considerations, the Audit and
Contract Review Committee recommended to the full board that the board approve
the continuance of the Advisory and Administration Contract.

     The full Board reviewed the factors considered by the Audit and Contract
Review Committee and also gave substantial consideration to the fees payable
under the contract. In this regard, the Board evaluated UBS Global AM's planned
waiver of 0.20% of the advisory fee and UBS Global AM's profitability with
respect to the Fund, including consideration of both the actual dollar amount of
fees paid by the Fund directly to UBS Global AM and so-called "fallout benefits"
to UBS Global AM or its affiliates, such as, for example, benefits derived from
serving as investment advisor to the Fund and the research services available to
UBS Global AM by reason of portfolio transactions executed for the Fund.

     Based on these considerations and the overall high-quality of the
personnel, operations, financial condition, investment advisory capabilities,
methodologies, and performance of UBS Global AM, the Board concluded the fees to
be paid to UBS Global AM under the Advisory and Administration Contract were
fair and reasonable, and the scope and quality of UBS Global AM's services to
the Fund was consistent with the Fund's operational requirements and sufficient
to approve the continuance of the Fund's Advisory and Administration Contract
with UBS Global AM.

     Under the Advisory and Administration Contract, UBS Global AM will not be
liable for any error of judgment or mistake of law or for any loss suffered by
the Fund in connection with the Advisory and Administration Contract, except a
loss resulting from willful misfeasance, bad faith or gross negligence on the
part of UBS Global AM in the performance of its duties or from reckless
disregard of its duties and obligations under the Advisory and Administration
Contract. The Advisory and Administration Contract is terminable by vote of the
Board or by the holders of a majority of the outstanding voting securities of
the Fund, at any time without penalty, on 60 days' written notice to UBS Global
AM. The Advisory and Administration Contract may also be terminated by UBS
Global AM on 60 days' written notice to the Fund. The Advisory and
Administration Contract terminates automatically upon its assignment.

                                       25


                             PORTFOLIO TRANSACTIONS

     The Fund purchases portfolio securities from dealers and underwriters as
well as from issuers. Securities are usually traded on a net basis with dealers
acting as principal for their own accounts without a stated commission. Prices
paid to dealers in principal transactions generally include a 'spread,' which is
the difference between the prices at which the dealer is willing to purchase and
sell a specific security at the time. When securities are purchased directly
from an issuer, no commissions or discounts are paid. When securities are
purchased in underwritten offerings, they include a fixed amount of compensation
to the underwriter.

     For purchases or sales with broker-dealer firms that act as principal, UBS
Global AM seeks best execution. Although UBS Global AM may receive certain
research or execution services in connection with these transactions, it will
not purchase securities at a higher price or sell securities at a lower price
than would otherwise be paid if no weight was attributed to the services
provided by the executing dealer. UBS Global AM may consider the sale of shares
of the Fund and of other funds it advises as a factor in the selection of
brokers or dealers to effect transactions for the Fund, subject to UBS Global
AM's duty to seek best execution. UBS Global AM may engage in agency
transactions in over-the-counter securities in return for research and execution
services. These transactions are entered into only pursuant to procedures that
are designed to ensure 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.

     Research services and information received from brokers or dealers are
supplemental to UBS Global AM's own research efforts and, when utilized, are
subject to internal analysis before being incorporated into its investment
processes. Information and research services furnished by brokers or dealers
through which or with which the Fund effects securities transactions may be used
by UBS Global AM in advising other funds or accounts and, conversely, research
services furnished to UBS Global AM by brokers or dealers in connection with
other funds or accounts that it advises may be used in advising the Fund.

     During the fiscal years ended September 30, 2003, 2002 and 2001, the Fund
paid no brokerage commissions. Therefore, the Fund has not allocated any
brokerage transactions for research, analysis, advice and similar services.
Investment decisions for the Fund and for other investment accounts managed by
UBS Global AM are made independently of one another in light of differing
considerations for the various accounts. However, the same investment decision
may occasionally be made for the Fund and one or more accounts. In those cases,
simultaneous transactions are inevitable. Purchases or sales are then averaged
as to price and allocated between the Fund and the other account(s) as to amount
in a manner deemed equitable to the Fund and the other account(s). While in some
cases this practice could have a detrimental effect upon the price or value of
the security as far as the Fund is concerned, or upon its ability to complete
its entire order, in other cases it is believed that simultaneous transactions
and the ability to participate in volume transactions will benefit the Fund.

PORTFOLIO TURNOVER

     The Fund anticipates that its annual portfolio turnover rate will not
exceed 100%; however, portfolio turnover may vary from year to year and will not
be a limiting factor when UBS Global AM deems portfolio changes appropriate. The
portfolio turnover rate will be calculated by dividing the lesser of the Fund's
annual sales or purchases of portfolio securities (exclusive of purchases or
sales of securities whose maturities at the time of acquisition were one year or
less) by the monthly average value of the long-term securities in the portfolio
during the year.

                            VALUATION OF COMMON STOCK

     The net asset value of the common stock is determined weekly, as determined
by or under the direction of the Board, and also is determined monthly as of the
close of regular trading on the NYSE on the last day of the month on which the
NYSE is open for trading. The net asset value per share of common stock is
computed by dividing the value of the securities held by the Fund plus any cash
or other assets (including interest and dividends accrued but not yet received
and earned discount) minus all liabilities (including accrued expenses) and the
liquidation preference of any outstanding Preferred Stock by the total number of
shares of common stock

                                       26


outstanding at such time. When market quotations are readily available, the
Fund's debt securities are valued based upon those quotations. When market
quotations for options and futures positions held by the Fund are readily
available, those positions are valued based upon such quotations. Market
quotations generally are not available for options traded in the OTC market.

     The Fund calculates its net asset value based on the current market value,
where available, for its portfolio securities. The Fund normally obtains market
values for its securities from independent pricing sources and broker-dealers.
Independent pricing sources may use reported last sale prices, current market
quotations, or valuations from computerized "matrix" systems that derive values
based on comparable securities. If a market value is not available from an
independent pricing source for a particular security, that security is valued at
fair value as determined in good faith by or under the direction of the Fund's
Board. The amortized cost method of valuation, which approximates market value,
generally is used to value short-term debt instruments with sixty days or less
remaining to maturity, unless the Board determines that this does not represent
fair value.

                                    TAXATION

     The following is a summary of the material federal tax considerations
affecting the Fund and its shareholders. In addition to the considerations
described below, which are applicable to any investment in the Fund, there may
be other federal, state, local or foreign tax considerations applicable to
particular investors. Prospective Shareholders are therefore urged to consult
their tax advisers with respect to the tax consequences to them of an investment
in the Fund.

TAXATION OF THE FUND

     GENERAL. The Fund intends to continue to qualify each taxable year for
treatment as a regulated investment company ("RIC") under Subchapter M of the
Internal Revenue Code. In each taxable year that the Fund so qualifies, the Fund
will be relieved of federal income tax on that part of its investment company
taxable income (consisting generally of taxable net investment income, net
short-term capital gain and net realized gains from certain hedging
transactions) and net capital gain (the excess of net long-term capital gain
over net short-term capital loss) that is distributed to its shareholders.

     In order to qualify for treatment as a RIC, the Fund must distribute
annually to its shareholders at least 90% of the sum of its net interest income
excludable from gross income under section 103(a) of the Internal Revenue Code
("tax-exempt income") plus its investment company taxable income ("Distribution
Requirement") and must meet several additional requirements. Among these
requirements are the following: (1) the Fund must derive at least 90% of its
gross income each taxable year from dividends, interest, payments with respect
to securities loans and gains from the sale or other disposition of securities,
or other income (including gains from options or futures contracts) derived with
respect to its business of investing in securities ("Income Requirement"); (2)
at the close of each quarter of the Fund's taxable year, at least 50% of the
value of its total assets must be represented by cash and cash items, US
government securities, securities of other RICs and other securities, with those
other securities limited, in respect of any one issuer, to an amount that does
not exceed 5% of the value of the Fund's total assets; and (3) at the close of
each quarter of the Fund's taxable year, not more than 25% of the value of its
total assets may be invested in securities (other than government securities or
the securities of other RICs) of any one issuer. If the Fund fails to qualify
for treatment as a RIC for any taxable year, it would be taxed as an ordinary
corporation on its taxable income for that year (even if that income was
distributed to its shareholders) and all distributions out of its earnings and
profits would be taxable to its shareholders as dividends (that is, ordinary
income). Such distributors generally would be eligible for (i) the dividends
received deduction in the case of corporate shareholders, and (ii) treatment as
"qualified dividends" in the case of individual shareholders.

     The Fund will be subject to a nondeductible 4% excise tax ("Excise Tax") to
the extent that it fails to distribute by the end of any calendar year at least
98% of the sum of its ordinary income (not including tax-exempt income) for that
year and its capital gain net income for the one-year period ending on October
31 of that year, plus certain other amounts. For these purposes, any such
taxable income retained by the Fund, and on which it pays federal income tax,
will be treated as having been distributed.

     Dividends on the APS will be treated as distributions by the Fund for
purposes of determining whether the Fund has satisfied the Distribution
Requirement (and thus will qualify for the deduction for dividends paid)

                                       27


and for purposes of the Excise Tax. While shares of the APS are outstanding, the
Fund may not declare any cash dividend or other distribution on its common stock
unless, at the time of the declaration, the Fund satisfies certain dividend
payment and asset coverage requirements. See "Description of
APS--Dividends--Restrictions on Dividends and Other Payments." Any such
suspension of distributions on the common stock could prevent the Fund from
satisfying the Distribution Requirement and avoiding imposition of the Excise
Tax. Upon any failure by the Fund to meet any of such dividend payment or asset
coverage requirements, however, the Fund currently intends to redeem a
sufficient number of shares of the APS to maintain or restore compliance with
such requirements and thus allow the Fund to make distributions necessary to
satisfy the Distribution Requirement and avoid imposition of the Excise Tax.

     The Fund may acquire zero coupon Municipal Obligations issued with original
issue discount. As the holder of such a security, the Fund would have to include
in gross income the original issue discount that accrues on the security for the
taxable year, even if the Fund receives no payment on the security during the
year. Because the Fund annually must distribute at least 90% of its tax-exempt
income, including any accrued original issue discount, to satisfy the
Distribution Requirement, it may be required in a particular year to distribute
as a dividend an amount that is greater than the total amount of cash it
actually receives. Those distributions will be made from the Fund's cash assets,
or from the proceeds of sales of portfolio securities or from borrowings, if
necessary. The Fund may realize taxable capital gains or losses from those
sales, which would increase or decrease the Fund's investment company taxable
income or net capital gain.

     HEDGING STRATEGIES. The use of hedging strategies, such as writing and
purchasing options and futures, involves complex rules that will determine for
income tax purposes the character and timing of recognition of certain gains and
losses that the Fund realizes in connection therewith. These rules also may
require the Fund to "mark to market" (that is, treat as sold for their fair
market value) at the end of each taxable year certain positions in its
portfolio, which may cause the Fund to recognize income without receiving cash
with which to make distributions necessary to satisfy the Distribution
Requirement and to avoid imposition of the Excise Tax. In that event, the Fund
might have to liquidate securities to enable it to make the required
distributions, which would cause it to recognize gains or losses.

     Income from transactions in options and futures derived by the Fund with
respect to its business of investing in securities will qualify as permissible
income under the Income Requirement.

     The Fund will monitor its hedging transactions and may make certain tax
elections to mitigate the adverse effects of the foregoing rules.

TAXATION OF SHAREHOLDERS

     DIVIDENDS AND OTHER DISTRIBUTIONS. The APS will constitute stock of the
Fund, and thus distributions with respect to the APS (other than distributions
in redemption of APS treated as exchanges of stock under section 302 of the
Internal Revenue Code) will constitute dividends to the extent of the Fund's
current or accumulated earnings and profits, as calculated for federal income
tax purposes. It is possible that the Internal Revenue Service ("Service") might
take a contrary position, however, asserting, for example, that the APS
constitute debt of the Fund. If this position were upheld, the discussion of the
treatment of distributions below would not apply to holders of the APS. Instead,
distributions by the Fund to those holders would constitute interest, would be
included in full in the recipient's income and would be taxed as ordinary
interest income. Counsel to the Fund believes that such a position, if asserted
by the Service, would be unlikely to prevail, and none of the distributions
would be treated as capital gains dividends, qualified dividend income, or as
exempt interest dividends.

     Distributions that the Fund designates as "exempt-interest dividends"
generally may be excluded from gross income by shareholders for federal income
tax purposes; those distributions may, however, be taxable for state and local
tax purposes. In addition, exempt-interest dividends are included for purposes
of determining the portion, if any, of a person's social security and railroad
retirement benefits that are includable in gross income. In order to pay
exempt-interest dividends, the Fund must (and intends 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 obligations the interest on which
is tax-exempt.

                                       28


     Interest on indebtedness incurred by a shareholder to purchase or carry
Shares is not deductible to the extent that interest relates to exempt-interest
dividends received from the Fund. If the Fund invests in certain PABs, the
portion of the Fund's exempt-interest dividends that is attributable to the
interest it earns thereon and that is specified in an annual notice from the
Fund must be included by its shareholders as an item of tax preference in
calculating their liability for the AMT. Corporate shareholders, however, must
include all of their exempt-interest dividends in calculating their adjusted
current earnings for purposes of the AMT. Accordingly, an investment in the Fund
may cause shareholders to be subject to (or result in shareholders' increased
liability under) the AMT. Because the Fund may from time to time invest as much
as 20% of its net assets in Municipal Obligations bearing income that is taxable
under the AMT, the Fund may not be an appropriate investment for investors who
are subject to the AMT or who would become subject to the AMT by reason of an
investment in the Fund.

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

     If the Fund invests in instruments that generate taxable interest income,
the portion of any Fund dividend attributable to that interest will be taxable
to its shareholders as ordinary income to the extent of its earnings and
profits. Distributions of the Fund's net capital gain, if any, will be taxable
to its shareholders as long-term capital gains, regardless of the length of time
they have held their Shares. For taxable years beginning on or before
December 31, 2008, provided holding period and other requirements are met by
both the Fund and the shareholder, dividends qualifying as "qualified dividend
income" will be taxed in the hands of individuals at the rates applicable to
long-term capital gain. The Fund does not expect a significant portion of Fund
distributions to be derived from qualified dividend income. Distributions in
excess of the Fund's earnings and profits will first reduce the adjusted tax
basis of a holder's Shares and, after the basis is reduced to zero, will
constitute capital gains to the holder (assuming the Shares are held as capital
assets). If, and for so long as, the Fund has outstanding any APS, it will be
required to allocate each particular type of its income for the taxable year
(such as tax-exempt income, net realized capital gains, and other taxable
income) between the classes of shares, common stock and APS, in proportion to
the total distributions paid to each such class for that year. The Fund may
notify the Auction Agent of the amount of any net capital gain and other taxable
income to be included in any dividend on the APS prior to the auction
establishing the Applicable Rate for such dividend; except for any such amount
of which the Fund so notifies the Auction Agent, the Fund anticipates that the
dividends paid on the APS will constitute exempt-interest dividends. It is not
expected that any portion of the Fund's distributions will be eligible for the
dividends-received deduction available for corporations.

     Although the matter is not free from doubt due to the absence of direct
regulatory or judicial authority, in the opinion of counsel to the Fund the
designation of distributions on the common stock and on the APS, in the
proportionate manner described above, as consisting of exempt-interest
dividends, net capital gain and other taxable income will be respected for
federal income tax purposes. Counsel has advised the Fund that, in its opinion,
if the Service were to challenge in court the Fund's designations of income and
gain, and the issue were properly litigated, the Service should not prevail. The
Fund will consider any guidance provided by the Service or the courts as to the
manner in which distributions on the common stock and on the APS may be so
designated. In the event of a reallocation, some of the dividends identified by
the Fund as exempt-interest dividends to holders of the APS may be
recharacterized as capital gains or other taxable income. In the event of such
recharacterization, the Fund would not be required to make payments to such
holders to offset the tax effect of such reallocation.

     If the Fund makes a Retroactive Taxable Allocation, it will pay Additional
Dividends to holders of the APS who are subject to the Retroactive Taxable
Allocation. See "Description of APS--Dividends--Additional Dividends." The
federal income tax consequences of Additional Dividends are uncertain. The Fund
intends to treat a holder as receiving a dividend distribution in the amount of
any Additional Dividend only as and when such Additional Dividend is paid. An
Additional Dividend generally will be designated by the Fund as an
exempt-interest dividend if such designation is allowable under applicable law.
However, the Service may assert that all or part of an Additional Dividend is a
taxable dividend.

                                       29


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

     The Fund will notify its shareholders following the end of each calendar
year of the amounts of exempt-interest dividends, taxable dividends, qualified
dividend income (if any), and capital gain distributions paid (or deemed paid)
that year and of any portion thereof that is an item of tax preference for
purposes of the AMT.

     SALES OF SHARES. Upon a sale, exchange, or other taxable disposition of
Shares, a shareholder will realize a taxable gain or loss equal to the
difference between his adjusted basis for the Shares and the amount realized.
Any such gain or loss will be treated as a capital gain or loss if the Shares
are capital assets in the shareholder's hands and will be a long-term capital
gain or loss if the Shares have been held for more than one year. Long-term
capital gain rates applicable to individuals have been temporarily reduced, in
general, to 15% (or 5% for individuals in the 10% or 15% rate brackets) for
taxable years beginning on or before December 31, 2008. Any loss realized on a
sale or exchange of Shares that were held for six months or less will be
disallowed to the extent of any exempt-interest dividends received on those
Shares and will be treated as a long-term, rather than as a short-term, capital
loss to the extent of any capital gain distributions received thereon. A loss
realized on a sale or exchange of shares of a series of APS also will be
disallowed to the extent that those shares are replaced by other shares of the
APS within a period of 61 days beginning 30 days before and ending 30 days after
the date of disposition of the shares. In that event, the basis of the
replacement shares will be adjusted to reflect the disallowed loss.

     BACKUP WITHHOLDING. The Fund is required to withhold at a current rate of
28% of all taxable dividends, capital gain distributions and repurchase proceeds
payable to any individuals and certain other noncorporate shareholders who do
not provide the Fund with a correct taxpayer identification number. Withholding
at that rate from taxable dividends and capital gain distributions also is
required for shareholders who otherwise are subject to backup withholding.

     RECENT TAX SHELTER REPORTING REGULATIONS. Under recently promulgated
Treasury regulations, if a shareholder recognizes a loss on disposition of the
Fund's shares of $2 million or more for an individual shareholder or $10 million
or more for a corporate shareholder, the shareholder must file with the IRS a
disclosure statement on Form 8886. Direct shareholders of portfolio securities
are in many cases excepted from this reporting requirement, but under current
guidance, shareholders of a RIC are not excepted. Future guidance may extend the
current exception from this reporting requirement to shareholders of most or all
regulated investment companies. The fact that a loss is reportable under these
regulations does not affect the legal determination of whether the taxpayer's
treatment of the loss is proper. Shareholders should consult their tax advisers
to determine the applicability of these regulations in light of their individual
circumstances.

                               DESCRIPTION OF APS

     The following is a brief description of the terms of the APS. This
description does not purport to be complete and is subject to and qualified in
its entirety by reference to the APS Provisions. Copies of the APS Provisions
are filed as exhibits to the Registration Statement of which this Prospectus is
a part and may be inspected, and copies thereof may be obtained, as described
under "Available Information" in the Prospectus. Terms used herein and not
otherwise defined shall have the meanings ascribed to them in the Glossary
immediately preceding the Appendices hereto.

GENERAL

     All shares of the APS will have a liquidation preference of $50,000 per
share plus an amount equal to accumulated but unpaid dividends (whether or not
earned or declared). The shares of APS will rank on a parity with shares of any
other series of Preferred Stock as to the payment of dividends and the
distribution of assets upon liquidation. So long as either Moody's or S&P is
rating the APS, the Fund may, without the vote of the holders of APS, issue
additional series of Preferred Stock, including APS, subject to applicable
provisions of the 1940 Act and to continuing compliance with the 1940 Act APS
Asset Coverage and the APS Basic Maintenance Amount, provided that (1) any such
additional series ranks on a parity with the then outstanding APS as to the

                                       30


payment of dividends and the distribution of assets upon liquidation and (2) the
Fund obtains written confirmation from Moody's or S&P, or both, as the case may
be, that the issuance of any such additional series would not impair the rating
then assigned by such rating agency to the APS.

     The Auction Agent will be the transfer agent, registrar, dividend
disbursing agent and redemption agent for the APS. The APS, when issued and sold
through this offering will be fully paid and nonassessable, will not be
convertible into common stock or other stock of the Fund and will have no
preemptive rights. The APS will not be subject to any sinking fund but will be
redeemable in the circumstances described under "Redemption."

DIVIDENDS

     GENERAL. The holders of APS will be entitled to receive, when, as and if
declared by the Board of the Fund, out of funds legally available therefor,
cumulative cash dividends at the Applicable Rate PER ANNUM there determined as
set forth below under "Determination of Dividend Rate," and no more (except as
otherwise provided below under "Additional Dividends"), payable on the
respective dates determined as set forth below.

     Dividends on the APS will accumulate at the Applicable Rate PER ANNUM from
the Date of Original Issue and, except as provided below, shall be payable as
described in the Prospectus. After the Initial Dividend Period, the Fund,
subject to certain conditions, may designate any Subsequent Dividend Period of
the APS as a Special Dividend Period which shall be such number of consecutive
days or whole years as the Board shall specify, subject to certain conditions.
Shares of the APS are redeemable by the Fund as described herein.

     If the Fund designates any Subsequent Dividend Period as a Special Dividend
Period, dividends will be payable: (i) with respect to a Special Dividend Period
of less than 35 days, the day after the last day thereof and (ii) with respect
to a Special Dividend period of 35 days or more, the first Business Day of each
calendar month thereafter, provided that in any calendar month in which an
Auction Date is scheduled to occur, dividends shall be payable on the first
Business Day next succeeding such Auction Date.

     After any Special Dividend Period, dividends on the APS shall be payable,
except as described below, as provided in the second preceding paragraph above,
subject to the option of the Fund to further designate from time to time any
Subsequent Dividend Period of a series as a Special Dividend Period.

     In the case of dividends that otherwise would be payable as set forth
above, if (i) the Sunday, Monday or Tuesday that would otherwise be the Dividend
Payment Date is not a Business Day, then dividends shall be payable on the first
Business Day that falls after such Sunday, Monday or Tuesday, or (ii) the
Wednesday, Thursday, Friday or Saturday that would otherwise be the Dividend
Payment Date is not a Business Day, then dividends shall be payable on the first
Business Day that falls prior to such Wednesday, Thursday, Friday or Saturday.

     Each dividend on the APS will be paid on the Dividend Payment Date therefor
to the Securities Depository to pay to the holders of record as their names
appear on the registry of Existing Holders of the Securities Depository on the
Business Day next preceding such Dividend Payment Date. Dividends in arrears for
any past Dividend Period may be declared and paid at any time, without reference
to any regular Dividend Payment Date, to the holders as their names appear on
the share books of the Fund on such date, not exceeding 15 days preceding the
payment date thereof, as may be fixed by the Board of the Fund.

     The Securities Depository, in accordance with its current procedures, is
expected to credit on each Dividend Payment Date dividends received from the
Fund to the accounts of the respective Agent Members in next-day funds. Each of
the initial Broker-Dealers, however, has represented to the Fund that such
Broker-Dealer (or if such Broker-Dealer does not act as Agent Member, one of its
affiliates) will make such dividend payments available in same-day funds on each
Dividend Payment Date to customers that use such Broker-Dealer or affiliate as
Agent Member. A holder of APS that does not use one of the initial
Broker-Dealers or an affiliate thereof as its Agent Member should contact the
Agent Member used by such holder to determine whether such Agent Member will
make dividend payments available to such holder in next-day or same-day funds.
If any Agent Member does not make such dividends available in same-day funds to
a holder, such holder who uses such Agent Member would not have same-day funds
available to it until the next Business Day, which, in the case of dividends
payable on a Friday, would be the following Monday if it is a Business Day.

                                       31


     DETERMINATION OF DIVIDEND RATE. The dividend rate on the APS during the
period from and after the Date of Original Issue thereof to and including the
last day of the Initial Dividend Period therefor will be equal to the rate PER
ANNUM set forth on the inside cover page of the Prospectus. For each Subsequent
Dividend Period thereafter, the dividend rate on the APS will be equal to the
rate PER ANNUM, except as provided below, that results from an auction on the
Auction Date next preceding such Subsequent Dividend Period.

     If an auction for any Subsequent Dividend Period of the APS is not held for
any reason or if the Fund fails to pay in a timely manner to the Auction Agent
the full amount of any dividend on, or Redemption Price of, shares of the APS
and such failure has not been cured as set forth below prior to any succeeding
Subsequent Dividend Period thereof then, subject to the next succeeding
paragraph, the dividend rate on the APS for any such Subsequent Dividend Period
will be the Maximum Rate for the APS on the Auction Date for such Subsequent
Dividend Period.

     If the Fund fails to pay in a timely manner to the Auction Agent the full
amount of any dividend on, or the Redemption Price of any of the APS during any
Rate Period thereof, and, prior to 12:00 Noon on the third Business Day next
succeeding the date on which such failure occurred, such failure shall not have
been cured in accordance with the next succeeding paragraph or the Fund shall
not have paid to the Auction Agent a late charge equal to the sum of: (1) if
such failure consisted of the failure timely to pay to the Auction Agent the
full amount of dividends with respect to any Dividend Period on the APS, an
amount computed by multiplying (x) 200% of the Reference Rate (or Treasury Rate,
if applicable) for the Rate Period during which such failure occurs on the
Dividend Payment Date for such Dividend Period by (y) a fraction, the numerator
of which shall be the number of days for which such failure has not been cured
in accordance with the next succeeding paragraph (including the day such failure
occurs and excluding the day such failure is cured) and the denominator of which
shall be 365, and applying the rate obtained against the aggregate liquidation
preference of the outstanding shares of the APS; and (2) if such failure
consisted of the failure timely to pay to the Auction Agent the Redemption Price
of the shares of the APS, if any, for which notice of redemption has been given
by the Fund, an amount computed by multiplying (x) 200% of the Reference Rate
(or Treasury Rate, if applicable) for the Rate Period during which such failure
occurs on the redemption date by (y) a fraction, the numerator of which shall be
the number of days for which such failure is not cured in accordance with the
next succeeding paragraph (including the day such failure occurs and excluding
the day such failure is cured) and the denominator of which shall be 365, and
applying the rate obtained against the aggregate liquidation preference of the
outstanding shares of the APS to be redeemed, then auctions for such series will
be suspended until such failure is so cured and the dividend rate for shares of
the APS for each Subsequent Dividend Period thereof commencing after such
failure to and including the Subsequent Dividend Period, if any, during which
such failure is so cured shall be a rate PER ANNUM equal to the Maximum Rate on
the Auction Date for each such Subsequent Dividend Period (but with the
prevailing rating for such shares, for purposes of determining such Maximum
Rate, being deemed to be "Below 'ba3'/BB-").

     Any such failure with respect to shares of the APS shall have been cured
(if such failure is not solely due to the willful failure of the Fund to make
the required payment to the Auction Agent) with respect to any Rate Period if,
not later than 12:00 Noon on the fourth Business Day preceding the Auction Date
for the Rate Period subsequent to such Rate Period, the Fund shall have paid to
the Auction Agent (i) all accumulated and unpaid dividends on the shares of the
APS and (ii) without duplication, the Redemption Price for the shares of the
APS, if any, for which notice of redemption has been given by the Fund.

     For the purposes of the foregoing, "AA Composite Commercial Paper Rate," on
any date for any Rate Period, means:

          (i)     (A) in the case of any Minimum Dividend Period or any Rate
     Period of between 7 and 35 days, the interest equivalent of the 30-day
     rate; provided, however, in the case of any Minimum Dividend Period of 7
     days or any Rate Period with 7 days, and if the "AA" Composite Commercial
     Paper Rate is being used to determine the Applicable Rate when all of the
     outstanding APS are subject to submitted hold orders, then the interest
     equivalent of the 7-day rate, and (B) in the case of any Rate Period with
     more than 35 days, the interest equivalent of the 180-day rate, on
     commercial paper placed on behalf of issuers whose corporate bonds are
     rated "AA"' by S&P or the equivalent of such rating by

                                       32


     S&P or another rating agency, as made available on a discount basis or
     otherwise by the Federal Reserve Bank of New York for the Business Day
     immediately preceding such date; or

          (ii)    in the event that the Federal Reserve Bank of New York does
     not make available any such rate, then the arithmetic average of such
     rates, as quoted on a discount basis or otherwise, by the Commercial Paper
     Dealers to the Auction Agent for the close of business on the Business Day
     next preceding such date.

     If any Commercial Paper Dealer does not quote a rate required to determine
the "AA" Composite Commercial Paper Rate, the "AA" Composite Commercial Paper
Rate shall be determined on the basis of the quotation or quotations furnished
by the remaining Commercial Paper Dealer or Commercial Paper Dealers and any
Substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers
selected by the Fund to provide such rate of rates not being supplied by any
Commercial Paper Dealer or Commercial Paper Dealers, as the case may be, or, if
the Fund does not select any such Substitute Commercial Paper Dealer or
Substitute Commercial Paper Dealers, by the remaining Commercial Paper Dealer or
Commercial Paper Dealers. For purposes of this definition, the "interest
equivalent" of a rate stated on a discount basis (a "discount rate") for
commercial paper of a given days' maturity shall be equal to the quotient
(rounded upwards to the next higher one-thousandth (.001) of 1%) of (A) the
discount rate divided by (B) the difference between (z) 1.00 and (y) a fraction
the numerator of which shall be the product of the discount rate times the
number of days in which such commercial paper matures and the denominator of
which shall be 360. As used herein, "Commercial Paper Dealers" means Goldman
Sachs Money Markets, L.P., Lehman Commercial Paper Incorporated, Merrill Lynch,
Pierce Fenner & Smith Incorporated and Smith Barney or, in lieu of any thereof,
their respective affiliates or successors, if such entity is a commercial paper
dealer. As used herein, "Substitute Commercial Paper Dealer" means Credit Suisse
First Boston LLC, Morgan Stanley & Co. Incorporated or their respective
affiliates or successors, if such entity is a commercial paper dealer, provided
that none of such entities shall be a Commercial Paper Dealer.

     "Taxable Equivalent of the Short-Term Municipal Bond Rate" on any date
means 90% of the quotient of (a) the PER ANNUM rate expressed on an Interest
Equivalent basis equal to the Kenny S&P 30-day High Grade Index or any successor
index (the "Kenny Index"), made available for the Business Day immediately
preceding such date but in any event not later than 8:30 A.M., Eastern time, on
such date by Kenny Information Systems Inc. or any successor thereto, (provided
that the use of such successor will not result in a reduction or withdrawal of
the rating of the APS by Moody's, if Moody's is then rating the APS, or by S&P,
if S&P is then rating the APS) based on 30-day yield evaluations at par of
bonds, the interest on which is excludable for regular federal income tax
purposes, of "high grade" component issuers selected by Kenny Information
Systems Inc or any such successor from time to time in its discretion, which
component issuers shall include, without limitation, issuers of general
obligation bonds but shall exclude any bonds the interest on which constitutes
an item of tax preference under section 57(a)(5) of the Internal Revenue Code or
successor provisions, for purposes of the AMT, divided by (b) 1.00 minus the
Marginal Tax Rate (expressed as a decimal); provided, however, that if the Kenny
Index is not made so available by 8:30 A.M., Eastern time, on such date by Kenny
Information Systems Inc. or any successor, the Taxable Equivalent of the
Short-Term Municipal Bond Rate shall mean the quotient of (i) the PER ANNUM rate
expressed on an Interest Equivalent basis equal to the most recent Kenny Index
so made available for any preceding Business Day, divided by (ii) 1.00 minus the
Marginal Tax Rate (expressed as a decimal).

     For the purposes of the foregoing, "Treasury Rate," on any date for any
Rate Period, means:

          (i)     the yield on the most recently auctioned non-callable direct
     obligations of the US Government (excluding " flower" bonds) with a
     remaining maturity within three months of the duration of such Rate Period,
     as quoted in THE WALL STREET JOURNAL on such date for the Business Day next
     preceding such date; or

          (ii)    in the event that any such rate is not published by THE WALL
     STREET JOURNAL, then the arithmetic average of the yields (expressed as an
     interest equivalent in the case of a Rate Period which is one year or less
     and expressed as a bond equivalent in the case of any longer Rate Period)
     on the most recently auctioned non-callable direct obligations of the US
     Government (excluding "flower" bonds) with a remaining maturity within
     three months of the duration of such Rate Period as quoted on a

                                       33


     discount basis or otherwise by the US Government Securities Dealers to the
     Auction Agent for the close of business on the Business Day immediately
     preceding such date.

     If any US Government Securities Dealer does not quote a rate required to
determine the Treasury Rate, the Treasury Rate shall be determined on the basis
of the quotation or quotations furnished by the remaining US Government
Securities Dealer or US Government Securities Dealers and any Substitute US
Government Securities Dealers selected by the Fund to provide such rate or rates
not being supplied by any US Government Securities Dealer or US Government
Securities Dealers, as the case may be, or, if the Fund does not select any such
Substitute US Government Securities Dealer or Substitute US. Government
Securities Dealers, by the remaining US Government Securities Dealer or US
Government Securities Dealers. As used herein, "US Government Securities Dealer"
means Goldman, Sachs & Co., Smith Barney and Morgan Guaranty Trust Company of
New York or their respective affiliates or successors, if such entity is a US
Government securities dealer. As used herein, "Substitute US Government
Securities Dealer" shall mean Credit Suisse First Boston and Merrill Lynch,
Pierce, Fenner & Smith Incorporated or their respective affiliates or
successors, if such entity is a US Government securities dealer, provided that
none of such entities shall be a US Government Securities Dealer.

     Except as set forth in the next sentence, no dividends shall be declared or
paid or set apart for payment on the shares of any class or series of shares of
the Fund's capital stock ranking, as to the payment of dividends, on a parity
with the APS for any period unless full cumulative dividends have been or
contemporaneously are declared and paid on the APS through its most recent
Dividend Payment Date. When dividends are not paid in full upon the APS through
the most recent Dividend Payment Date or upon the shares of any other class or
series of shares of the Fund's capital stock ranking on a parity as to the
payment of dividends with the APS through their most recent respective dividend
payment dates, all dividends declared upon the APS and any other such class or
series of stock ranking on a parity as to the payment of dividends with the APS
shall be declared pro rata so that the amount of dividends declared per share on
the APS and such other class or series of shares shall in all cases bear to each
other the same ratio that accumulated dividends per share on the APS and such
other class or series of stock bear to each other (for purposes of this
sentence, the amount of dividends declared per share shall be based on the
Applicable Rate for such shares for the Dividend Periods during which dividends
were not paid in full). Holders of the APS shall not be entitled to any
dividend, whether payable in cash, property or capital shares, in excess of full
cumulative dividends, as provided in the APS Provisions, on the APS. No
interest, or sum of money in lieu of interest, will be payable in respect of any
dividend payment or payments on the APS which may be in arrears, and, except as
otherwise provided herein, no additional sum of money will be payable in respect
of any such arrearage.

     The amount of dividends per share payable on the APS on any date on which
dividends shall be payable on such shares shall be computed by multiplying the
Applicable Rate in effect for such Dividend Period or Dividend Periods or parts
thereof for which dividends have not been paid by a fraction, the numerator of
which shall be the number of days in such Dividend Period or Dividend Periods or
parts thereof and the denominator of which shall be 365 if such Dividend Period
is a Rate Period of less than 1 year and 360 for all other Rate Periods, and
applying the rate obtained against $50,000. Any dividend payment made on the APS
shall first be credited against the earliest accumulated but unpaid dividends
due with respect to such APS.

     DESIGNATION OF SPECIAL DIVIDEND PERIODS. The Fund, at its option, may
designate any succeeding Subsequent Dividend Period of the APS as a Special
Dividend Period which shall consist of such number of days or whole years as the
Board shall specify; provided, however, that such designation shall be effective
only if (i) notice thereof shall have been given as provided herein, (ii) any
failure to pay in a timely manner to the Auction Agent the full amount of any
dividend on, or the Redemption Price of Series C shares of the APS shall have
been cured as set forth above under "Dividends--Determination of Dividend Rate,"
(iii) sufficient clearing bids for the APS shall have existed in an auction held
on the Auction Date immediately preceding the first day of such proposed Special
Dividend Period, (iv) if the Fund shall have mailed a notice of redemption with
respect to any shares of the APS, as described under "Redemption--Notice of
Redemption below, the Redemption Price with respect to such shares shall have
been deposited with the Auction Agent, and (v) in the event the Fund wishes to
designate any succeeding Subsequent Dividend Period for the APS as a Special
Dividend Period consisting of more than 28 days, the Fund has received written
confirmation from S&P (if S&P is then rating the

                                       34


APS) and Moody's (if Moody's is then rating the APS) that such designation would
not affect the rating then assigned by S&P and Moody's, respectively, to the
APS.

     If the Fund proposes to designate any succeeding Subsequent Dividend Period
as a Special Dividend Period of more than 28 days, not less than 20 nor more
than 30 days prior to the date the Fund proposes to designate as the first day
of such Special Dividend Period (which shall be such day that would otherwise be
the first day of a Minimum Dividend Period), notice shall be (i) published or
caused to be published by the Fund in a newspaper of general circulation to the
financial community in The City of New York, New York, which carries financial
news, and (ii) communicated by the Fund by telephonic or other means to the
Auction Agent and confirmed in writing promptly thereafter. Each such notice
shall state (A) that the Fund may exercise its option to designate a succeeding
Subsequent Dividend Period of the APS as a Special Dividend Period, specifying
the first day thereof and (B) that the Fund will by 11:00 A.M., Eastern time, on
the second Business Day next preceding such date notify the Auction Agent, who
will promptly notify the Broker-Dealers, of either (x) its determination,
subject to certain conditions, to exercise such option, in which case the Fund
shall specify the Special Dividend Period designated and the terms of the
Specific Redemption Provisions, if any, or (y) its determination not to exercise
such option.

     No later than 11:00 A.M., Eastern time, on the second Business Day next
preceding the first day of any proposed Special Dividend Period, the Fund shall
deliver to the Auction Agent, who will promptly deliver to the Broker-Dealers,
either:

          (i)     a notice stating (A) that the Fund has determined to designate
     the next succeeding Rate Period of the APS as a Special Dividend Period,
     specifying the same and the first day thereof (B) the Auction Date
     immediately prior to the first day of such Special Dividend Period, (C) the
     terms of the Specific Redemption Provisions, if any, (D) that such Special
     Dividend Period shall not commence if (1) on such Auction Date sufficient
     clearing bids shall not exist (in which case the succeeding Rate Period
     shall be a Minimum Dividend Period) or (2) the Fund shall have failed to
     pay in a timely manner to the Auction Agent the full amount of any dividend
     on, or the Redemption Price of, shares of the APS, as set forth above under
     "Dividends -- Determination of Dividend Rate," prior to the first day of
     such Special Dividend Period and (E) the scheduled Dividend Payment Dates
     during such Special Dividend Period; provided, that, if the proposed
     Special Dividend Period consists of more than 28 days, such notice will be
     accompanied by an APS Basic Maintenance Report showing, as of the third
     Business Day next preceding such proposed Special Dividend Period, (1) a
     Discounted Value of Moody's Eligible Assets, assuming for purposes of
     calculating such Discounted Value in connection with an APS Basic
     Maintenance Report required to be prepared pursuant to the APS Provisions,
     a Moody's Exposure Period of "eight weeks or less but greater than seven
     weeks" (if Moody's is then rating the APS) and (2) a Discounted Value of
     S&P Eligible Assets (if S&P is then rating the APS), each at least equal to
     APS Basic Maintenance Amount as of such Business Day (assuming for purposes
     of the foregoing calculation that the Maximum Rate is the Maximum Rate on
     such Business Day as if such Business Day were the Auction Date for the
     proposed Special Dividend Period); or

          (ii)    a notice stating that the Fund has determined not to exercise
     its option to designate a Special Dividend Period and that the next
     succeeding Rate Period shall be a Minimum Dividend Period.

     If the Fund fails to deliver either such notice with respect to any
designation of any proposed Special Dividend Period to the Auction Agent by
11:00 A.M., Eastern time, on the second Business Day next preceding the first
day of such proposed Special Dividend Period, the Fund shall be deemed to have
delivered a notice to the Auction Agent with respect to such Special Dividend
Period to the effect set forth in clause (ii) above.

     RESTRICTIONS ON DIVIDENDS AND OTHER PAYMENTS. Under the 1940 Act, the Fund
may not declare dividends (other than dividends payable in common stock) or
other distributions with respect to common stock, or purchase any such shares
if, at the time of the declaration or purchase, as applicable (and after giving
effect thereto), asset coverage (as defined in and determined pursuant to the
1940 Act) with respect to the outstanding Preferred Stock, including the APS,
would be less than 200% (or such other percentage as may in the future be
required by law).

                                       35


     In addition, for so long as any of the APS are outstanding, except as
otherwise set forth herein, (A) the Fund may not declare, pay or set apart for
payment any dividend or other distribution (other than a dividend or other
distribution paid in shares of or options, warrants or rights to subscribe for
or purchase, common stock or other capital stock of the Fund, if any, ranking
junior to the APS as to the payment of dividends and the distribution of assets
upon liquidation) in respect of common stock or any other stock of the Fund
ranking junior to or on a parity with the APS as to the payment of dividends or
the distribution of assets upon liquidation, or call for redemption, redeem,
purchase or otherwise acquire for consideration any common stock or any other
such junior stock (except by conversion into or exchange for stock of the Fund
ranking junior to the APS as to the payment of dividends and the distribution of
assets upon liquidation), or any such parity stock (except by conversion into or
exchange for capital shares of the Fund ranking junior to or on a parity with
the APS as to payment of dividends and the distribution of assets upon
liquidation), unless (1) full cumulative dividends on shares of the APS through
its most recently ended Dividend Period shall have been paid or shall have been
declared and sufficient funds for the payment thereof deposited with the Auction
Agent and (2) the Fund has redeemed the full number of shares of the APS
required to be redeemed by any provision for mandatory redemption contained in
the APS Provisions, and (B) if either Moody's a S&P is rating the APS, the Fund
may not declare, pay or set apart for payment any dividend or other distribution
(other than a dividend or distribution paid in shares of, or options, warrants
or rights to subscribe for or purchase, common stock or other shares, if any,
ranking junior to the APS as to the payment of dividends and the distribution of
assets upon liquidation) in respect of common stock or any other shares of the
Fund ranking junior to the APS as to the payment of dividends or the
distribution of assets upon liquidation, or call for redemption, redeem,
purchase or otherwise acquire for consideration any shares of common stock or
any other such junior stock (except by conversion into or exchange for stock of
the Fund ranking junior to the APS as to the payment of dividends or the
distribution of assets upon liquidation), unless immediately after such
transaction the Discounted Values of the Moody's Eligible Assets and of the S&P
Eligible Assets would each at least equal the APS Basic Maintenance Amount. See
"Investment Objective and Policies--Rating Agency Guidelines," "Asset
Maintenance" and "Redemption."

     Under the Internal Revenue Code, the Fund must, among other things,
distribute at least 90% of the sum of its investment company taxable income and
its net tax-exempt income each year in order to maintain its qualification for
tax treatment as a RIC. The foregoing limitations on dividends, other
distributions and purchases may in certain circumstances impair the Fund's
ability to maintain such qualification. The Fund currently intends, however, to
exercise its optional redemption rights to redeem a portion of the APS when
necessary to preserve such qualification. See "Taxation."

     ADDITIONAL DIVIDENDS. If the Fund retroactively allocates any net capital
gains or other income taxable for federal income tax purposes to the APS by
reason of the fact that such allocation is made as a result of (i) the
realization of net capital gains or other income taxable for federal income tax
purposes, (ii) the redemption of all or a portion of the outstanding APS or
(iii) the liquidation of the Fund (such allocation is referred to herein as a
"Retroactive Taxable Allocation"), the Fund will simultaneously, if practicable,
with such allocation but in no event later than 270 days after the end of the
Fund's taxable year for which a Retroactive Taxable Allocation is made, provide
notice thereof to the Auction Agent and to each holder of APS (initially ______,
as nominee of ________) during such taxable year at such holder's address as the
same appears or last appeared on the stock books of the Fund. The Fund will,
within 30 days after such notice is given to the Auction Agent, pay to the
Auction Agent (who will then distribute to such holders of shares of APS), out
of funds legally available therefor, an amount equal to the aggregate Additional
Dividends (as defined below) with respect to all Retroactive Taxable Allocations
made to such holders for the taxable year in question. See "Taxation."

     "Additional Dividends" means the payment to a holder of APS of an amount
which, when taken together with the aggregate amount of Retroactive Taxable
Allocations made to such holder with respect to the taxable year in question,
would cause such holder's dividends in dollars (after federal income tax
consequences as described below) from the aggregate of both the Retroactive
Taxable Allocations and the Additional Dividends to be equal to the dollar
amount of the dividends which would have been received by such holder if the
amount of the aggregate Retroactive Taxable Allocations would have been
excludable from the gross income of such holder. State taxes imposed on the
Additional Dividends, however; may reduce the amount of after tax cash a holder
would have had if there were no Retroactive Taxable Allocation. Such Additional
Dividends shall be calculated (i) without consideration being given to the time
value of money; (ii) assuming that no holder of

                                       36


APS is subject to the AMT with respect to dividends received from the Fund; and
(iii) assuming that each Retroactive Taxable Allocation would be taxable in the
hands of each holder of APS at the maximum marginal regular federal individual
income tax rate applicable to ordinary income or net capital gain, as
applicable, or the maximum marginal regular federal corporate income tax rate,
whichever is greater, in effect during the taxable year in question.

ASSET MAINTENANCE

     1940 ACT APS ASSET COVERAGE. The Fund will be required under the APS
Provisions to maintain, with respect to the APS, as of the last Business Day of
each month in which any APS are outstanding, asset coverage of at least 200%
with respect to senior securities which are stock, including APS (or such other
asset coverage as may in the future be specified in or under the 1940 Act as the
minimum asset coverage for senior securities which are stock of a closed-end
investment company as a condition of declaring dividends on its common stock).
If the Fund fails to maintain such asset coverage in accordance with the
requirements of the rating agency or agencies then rating the APS ("1940 Act APS
Asset Coverage") and such failure is not cured as of the last Business Day of
the following month ("1940 Act Cure Date"), the Fund will be required in certain
circumstances to redeem certain of the shares of APS. See "Redemption" below.

     APS BASIC MAINTENANCE AMOUNT. So long as any APS are outstanding, the Fund
will be required under the APS Provisions to maintain as of each Business Day (a
"Valuation Date") assets having in the aggregate a Discounted Value at least
equal to the APS Basic Maintenance Amount established by the rating agency or
agencies then rating the APS. If the Fund fails to meet such requirement on any
Valuation Date and such failure is not cured on or before the third Business Day
after such Valuation Date ("APS Basic Maintenance Cure Date"), the Fund will be
required in certain circumstances to redeem certain of the shares of APS. See
"Redemption" below.

     The "APS Basic Maintenance Amount" as of any Valuation Date is defined as
the dollar amount equal to the sum of:

          (A)     (i) the product of the number of APS outstanding on such date
     multiplied by $50,000;

                  (ii) the aggregate amount of dividends that will have
     accumulated at the Applicable Rate (whether or not earned or declared) to
     (but not including) the respective first scheduled Auction Dates for each
     of the APS outstanding that follow such Valuation Date (or to the 47th day
     after such Valuation Date, if such 47th day is earlier than such first
     following scheduled Auction Date);

                  (iii) the amount equal to the Projected Dividend Amount (based
     on the number of APS outstanding on such date);

                  (iv) the amount of anticipated Fund expenses for the 90 days
     subsequent to such Valuation Date;

                  (v) the amount of the Fund's Maximum Potential Additional
     Dividends Liability as of such Valuation Date;

                  (vi) the amount of any premium payable pursuant to a Premium
     Call Period; and

                  (vii) any current liabilities as of such Valuation Date to the
     extent not reflected in any of (A)(i) through (A)(vi) (including, without
     limitation, any amounts described below as required to be treated as
     liabilities in connection with the Fund's transactions in futures and
     options and including any payables for Municipal Obligations purchased as
     of such Valuation Date) less

          (B)     either (i) the fair value of any Fund assets irrevocably
     deposited by the Fund for the payment of any of (A)(i) through (A)(vii) if
     such assets mature prior to or on the date of payment of the liability for
     which such assets are deposited and are either securities issued or
     guaranteed by the United States Government or have a rating assigned by
     Moody's of P-1, VMIG-1 or MIG-1 (or, with respect to S&P, SP-1+ or A-1+) or
     (ii) the Discounted Value of such assets.

     For purposes of the foregoing, "Maximum Potential Additional Dividends
Liability," as of any Valuation Date, means the aggregate amount of Additional
Dividends that would be due if the Fund were to make Retroactive Taxable
Allocations, with respect to any taxable year, estimated based upon dividends
paid

                                       37


and the amount of undistributed realized net capital gains and other taxable
income earned by the Fund, as of the end of the calendar month immediately
preceding such Valuation Date, and assuming such Additional Dividends are fully
taxable.

     For purposes of the APS Basic Maintenance Amount in connection with S&P's
ratings of the APS, with respect to any transactions by the Fund in futures
contracts, the Fund shall include as liabilities (i) 30% of the aggregate
settlement value, as marked to market, of any outstanding futures contracts
based on the Municipal Index which are owned by the Fund plus (ii) 25% of the
aggregate settlement value, as marked to market, of any outstanding futures
contracts based on Treasury Bonds which contracts are owned by the Fund. For
purposes of the APS Basic Maintenance Amount in connection with Moody's rating
of the APS, with respect to any transactions by the Fund in securities
operations, the Fund shall include as liabilities (i)10% of the exercise price
of a call option written by the Fund and (ii) the exercise price of any written
put option.

     The Discount Factors and guidelines for determining the market value of the
Fund's portfolio holdings, described above under the heading "Investment
Objective and Policies--Rating Agency Guidelines," have been based on criteria
established in connection with rating the APS. These factors include, but are
not limited to, the sensitivity of the market value of the relevant asset to
changes in interest rates, the liquidity and depth of the market for the
relevant asset, the credit quality of the relevant asset (for example, the lower
the rating of a debt obligation, the higher the related discount factor) and the
frequency with which the relevant asset is marked to market. In no event shall
the Discounted Value of any asset of the Fund exceed its unpaid principal
balance or face amount as of the date of calculation. The Discount Factors
relating to any asset of the Fund and the APS Basic Maintenance Amount, the
assets eligible for inclusion in the calculation of the Discounted Value of the
Fund's portfolio and certain definitions and methods of calculation relating
thereto may be changed from time to time by the Fund without approval of the
holders of the APS, but only in the event the Fund receives written confirmation
from the appropriate rating agency that any such change would not impair the
rating then assigned to the APS by such rating agency. A rating agency's
Discount Factors and guidelines will apply to the APS so long as such rating
agency is rating the APS.

     On or before 5:00 PM., Eastern time, on the third Business Day after a
Valuation Date on which the Fund fails to maintain a Discounted Value of
Moody's Eligible Assets or S&P Eligible Assets in an amount greater than or
equal to the APS Basic Maintenance Amount, and on the third Business Day
after the APS Basic Maintenance Cure Date with respect to such Valuation
Date, the Fund is required to deliver to the Auction Agent (so long as either
Moody's or S&P is rating the APS) a report with respect to the calculation of
the APS Basic Maintenance Amount and the value of its portfolio holdings as
of the date of such failure or such cure date, as the case may be ("APS Basic
Maintenance Report"). The Fund will also deliver an APS Basic Maintenance
Report to S&P (if S&P is then rating the APS) and Moody's (if Moody's is then
rating the APS) on a monthly basis (check) and: (i) on any Valuation Date on
which the Discounted Value of Moody's Eligible Assets or S&P Eligible Assets,
as the case may be, is greater than the APS Basic Maintenance Amount by 5% or
less or (ii) on any date on which the Fund redeems common stock. Within ten
Business Days after delivery of such report relating to the last Business Day
of each month, the Fund will deliver a letter prepared by the Fund's
independent accountants regarding the accuracy of the calculations made by
the Fund in its most recent APS Basic Maintenance Report. If any such letter
prepared by the Fund's independent accountants shows that an error was made
in the most recent APS Basic Maintenance Report, the calculation or
determination made by the Fund's independent accountants will be conclusive
and binding on the Fund.

MINIMUM LIQUIDITY LEVEL

     Pursuant to S&P guidelines, so long as S&P is rating the APS, the Fund will
be required under the APS Provisions to have, as of each Valuation Date, Deposit
Securities with maturity or tender dates not later than the days preceding the
first respective Dividend Payment Dates (collectively "Dividend Coverage
Assets") for each share of the APS outstanding that follow such Valuation Date
and having a value not less than the Dividend Coverage Amount (the "Minimum
Liquidity Level"). So long as S&P is rating the APS, if, as of each Valuation
Date, the Fund does not have the required Dividend Coverage Assets, the Fund
will, as soon as practicable, adjust its portfolio in order to meet the Minimum
Liquidity Level. The "Dividend Coverage Amount," as of any Valuation Date, means
(A) the aggregate amount of dividends that will accumulate on each share of APS
to (but not including) the first Dividend Payment Date for each share of APS
outstanding that follows such Valuation

                                       38


Date plus any liabilities that will become payable prior to or on such payment
date; less (B) the combined value of Deposit Securities irrevocably deposited
for the payment of dividends on the APS and Receivables for Municipal
Obligations Sold which become due prior to the Dividend Payment Date and
interest with respect to Municipal Obligations which is payable to the Fund
prior to the Dividend Payment Date. "Deposit Securities" generally means cash
and Municipal Obligations rated at least A-1+ or SP-1+ by S&P. The definitions
of "Deposit Securities," "Dividend Coverage Assets" and "Dividend Coverage
Amount" may be changed from time to time by the Fund without approval of the
holders of the APS, but only in the event the Fund receives written confirmation
from S&P that any such change would not impair the rating then assigned by S&P
to the APS.

REDEMPTION

     OPTIONAL REDEMPTION. After the Initial Dividend Period, and upon giving a
notice of redemption, as provided below, the Fund at its option may redeem
shares of the APS, in whole or in part, on the second Business Day not preceding
any Dividend Payment Date applicable to those shares of APS called for
redemption, out of funds legally available therefor, at the Optional Redemption
Price; provided that, during a Special Dividend Period of 365 days or more, none
of the APS will be subject to optional redemption during any Non-Call Period.
Also, shares of the APS may not be redeemed in part if after such partial
redemption fewer than 250 shares of APS remain outstanding.

     If fewer than all of the outstanding shares of APS are to be redeemed as
set forth above, the number of shares of APS to be redeemed shall be determined
by the Board, and such shares shall be redeemed pro rata from the holders of
record (initially ______________ with respect to APS Series C, as nominee of the
Securities Depository) in proportion to the number of such shares held by such
holders. Since the nominee of the Securities Depository is the only record
holder of shares of the APS, the Securities Depository will determine the number
of shares to be redeemed from the account of the Agent Member of each beneficial
owner. An Agent Member may determine to redeem shares from some beneficial
owners (which may include an Agent Member holding shares for its own account)
without redeeming shares from the accounts of other beneficial owners.

     The Fund may not give a notice of redemption relating to an optional
redemption as described above unless, on the date on which the Fund intends to
give such notice, (a) the Fund has available certain Deposit Securities with
maturity or tender dates not later than the day preceding the applicable
redemption date and having a value not less than the amount (including any
applicable premium) due to holders of APS by reason of the redemption of such
APS on such redemption date and (b) the Fund would have assets with an aggregate
Discounted Value at least equal to the APS Basic Maintenance Amount immediately
subsequent to such redemption, if such redemption were to occur on such date,
and on the date of redemption.

     MANDATORY REDEMPTION. The Fund will be required to redeem, at the Mandatory
Redemption Price, certain of the APS to the extent permitted under the 1940 Act
and Maryland law, if the Fund fails to maintain a Discounted Value of Moody's
Eligible Assets or S&P Eligible Assets in an amount greater than or equal to the
APS Basic Maintenance Amount or fails to maintain the 1940 Act APS Asset
Coverage and such failure is not cured on or before the APS Basic Maintenance
Cure Date or the 1940 Act Cure Date (herein respectively referred to as a "Cure
Date"), as the case may be. The number of APS to be redeemed will be equal to
the lesser of (a) the minimum number of APS the redemption of which, if deemed
to have occurred immediately prior to the opening of business on the Cure Date,
together with all other Preferred Stock subject to redemption or retirement,
would result in the satisfaction of the APS Basic Maintenance Amount or the 1940
Act APS Asset Coverage, as the case may be, on such Cure Date (provided that, if
there is no such minimum number of APS and other Preferred Stock the redemption
of which would have such result, all of the APS and Preferred Stock then
outstanding will be redeemed), and (b) the maximum number of APS, together with
all other Preferred Stock subject to redemption or retirement, that can be
redeemed out of funds expected to be legally available therefor. In determining
the APS required to be redeemed in accordance with the foregoing, the Fund will
allocate the number required to be redeemed to satisfy the APS Basic Maintenance
Amount or the 1940 Act APS Asset Coverage, as the case may be, pro rata among
the APS and other Preferred Stock subject to redemption provisions similar to
those contained in this paragraph.

     The Fund is required to effect such a mandatory redemption not earlier than
20 days and not later than 40 days after such Cure Date, except that if the Fund
does not have funds legally available for the redemption of

                                       39


all of the required number of APS AND other Preferred Stock which are subject to
mandatory redemption or the Fund otherwise is unable to effect such redemption
on or prior to 40 days after such Cure Date, the Fund will redeem those shares
of APS and other Preferred Stock which it was unable to redeem on the earliest
practicable date on which it is able to effect such redemption. If fewer than
all of the outstanding shares of APS are to be redeemed pursuant to a mandatory
redemption, the number of shares of the APS to be redeemed shall be redeemed pro
rata from the holders of such shares in proportion to the number of such shares
held by such holders, in the same manner as described above in respect of
optional redemptions of fewer than all outstanding shares of APS.

     NOTICE OF REDEMPTION. The Fund is required to give 30 days' Notice of
Redemption. In the event the Fund obtains appropriate exemptive or no-action
relief from the SEC, which is not assured, the number of days' notice required
for a mandatory redemption may be reduced by the Board of the Fund to as few as
two Business Days if Moody's and S&P each has agreed in writing that the revised
notice provision would not adversely affect its then-current ratings of the APS.
The Auction Agent will use its reasonable efforts to provide telephonic notice
to each holder of APS called for redemption not later than the close of business
on the Business Day on which the Auction Agent determines the shares to be
redeemed (as described above) (or, during the occurrence of a Failure to Deposit
with respect to such shares, not later than the close of business on the
Business Day immediately following the day on which the Auction Agent receives
Notice of Redemption from the Fund). Such telephonic notice will be confirmed
promptly in writing not later than the close of business on the third Business
Day preceding the redemption date by notice sent by the Auction Agent to each
holder of record of APS called for redemption, the Broker-Dealers and the
Securities Depository. Every Notice of Redemption and other redemption notice
with respect to APS will state: (1) the redemption date, (2) the number of
shares of the APS to be redeemed, (3) the redemption price, (4) that dividends
on the APS to be redeemed will cease to accumulate as of such redemption date
and (3) the provision of the APS Provisions pursuant to which such shares are
being redeemed. No defect in the Notice of Redemption or other redemption notice
or in the transmittal or the mailing thereof will affect the validity of the
redemption proceedings, except as required by applicable law. If fewer than all
shares of any series held by any holder are to be redeemed, the notice of
Redemption mailed to such holder shall also specify the number of shares of the
APS to be redeemed from such holder.

     OTHER REDEMPTION PROCEDURES. To the extent that any redemption for which
notice of redemption has been given is not made by reason of the absence of
legally available funds therefor, such redemption will be made as soon as
practicable to the extent such funds become available. Failure to redeem APS
will be deemed to exist at any time after the date specified for redemption in a
notice of redemption when the Fund shall have failed, for any reason whatsoever,
to deposit with the Auction Agent the Optional Redemption Price or Mandatory
Redemption Price, as the case may be, with respect to any shares for which such
notice of redemption has been given. Notwithstanding the fact that the Fund may
not have redeemed the APS for which a notice of redemption has been given,
dividends may be declared and paid on APS and will include those APS for which
notice of redemption has been given.

     Upon the deposit of funds sufficient to redeem APS with the Auction Agent
and the giving of notice of redemption, dividends on such APS shares will cease
to accumulate and such shares will no longer be deemed outstanding for any
purpose, and all rights of the holders of the APS so called for redemption will
cease and terminate, except the right of the holders thereof to receive the
Optional Redemption Price or Mandatory Redemption Price, as the case may be, but
without any interest or other additional amount, except as otherwise provided
above under "Dividends--Additional Dividends." Upon surrender in accordance with
the notice of redemption of the certificates for any APS so redeemed (properly
endorsed or assigned for transfer, if the Board shall so require and the notice
shall so state), the Optional Redemption Price or Mandatory Redemption Price, as
the case may be, shall be paid by the Auction Agent to the holders of APS
subject to redemption. In the case that fewer than all of the APS represented by
any such certificate are redeemed, a new certificate shall be issued,
representing the unredeemed shares, without cost to the holder thereof. The Fund
will be entitled to receive from the Auction Agent, promptly after the date
fixed for redemption, any cash deposited with the Auction Agent in excess of (i)
the aggregate Optional Redemption Price or Mandatory Redemption Price, as the
case may be, of the APS called for redemption on such date and (ii) all other
amounts to which holders of APS called for redemption may be entitled. Any funds
so deposited that are unclaimed at the end of 90 days from such

                                       40


redemption date will, to the extent permitted by law, be repaid to the Fund,
after which time the holders of APS so called for redemption may look only to
the Fund for payment of the Optional Redemption Price or Mandatory Redemption
Price, as the case may be, and all other amounts to which they may be entitled.
The Fund will be entitled to receive, from time to time after the date fixed for
redemption, any interest on the funds so deposited.

     Notwithstanding the foregoing, if any dividends on the APS are in arrears,
no shares of the APS shall be redeemed unless all outstanding shares of the APS
are simultaneously redeemed, and the Fund shall not purchase or otherwise
acquire any shares of the APS; provided, however that the foregoing shall not
prevent the purchase or acquisition of all outstanding shares of the APS
pursuant to the successful completion of an otherwise lawful purchase or
exchange offer made on the same terms to, and accepted by holders of all
outstanding shares of the APS.

     Except as described above with respect to redemptions and under "The
Auction--Orders by Existing Holders and Potential Holders," the APS Provisions
do not prohibit the Fund or any affiliate of the Fund from purchasing or
otherwise acquiring any APS.

     The Fund has the right to arrange for others to purchase from the holders
thereof APS which are to be redeemed as described above.

LIQUIDATION

     Upon a liquidation of the Fund, whether voluntary or involuntary, the
holders of APS then outstanding will be entitled to receive and to be paid out
of the assets of the Fund available for distribution to its shareholders, before
any payment or distribution shall be made on the common stock or on any other
class of stock of the Fund ranking junior to the APS upon liquidation, an amount
equal to the liquidation preference with respect to the APS. The liquidation
preference for the APS shall be $50,000 per share, plus an amount equal to all
dividends thereon (whether or not earned or declared) accumulated but unpaid to
the date of final distribution in same-day funds, together with any applicable
Additional Dividends in connection with the liquidation of the Fund. After the
payment to the holders of the APS of the full preferential amounts provided for
as described herein, the holders of APS as such shall have no right or claim to
any of the remaining assets of the Fund. In the event the assets of the Fund
available for distribution to the holders of the APS upon any liquidation of the
Fund, whether voluntary or involuntary, shall be insufficient to pay in full all
amounts to which such holders are entitled, no such distribution shall be made
on account of any shares of any other class or series of Preferred Stock ranking
on a parity with the APS upon such liquidation unless proportionate distributive
amounts shall be paid on account of the APS, ratably, in proportion to the full
distributable amounts for which holders of all such parity shares are
respectively entitled upon such liquidation. Subject to the rights of the
holders of shares of any series or class or classes of stock ranking on a parity
with the APS with respect to the distribution of assets upon liquidation of the
Fund, after payment shall have been made in full to the holders of the APS as
described herein, but not prior thereto, any other series or class or classes of
the Fund's capital stock ranking junior to the APS with respect to the
distribution of assets upon liquidation shall, subject to the respective terms
and provisions (if any) applying thereto, be entitled to receive any and all
assets remaining to be paid or distributed, and the holders of the APS shall not
be entitled to share therein.

     Neither the sale of all or substantially all the property or business of
the Fund, nor the merger or consolidation of the Fund into or with any other
corporation nor the merger or consolidation of any other corporation into or
with the Fund shall be a liquidation, whether voluntary or involuntary, for the
purposes of the foregoing paragraph.

VOTING RIGHTS

     Except as otherwise indicated in the Fund's Prospectus or as otherwise
required by applicable law, holders of the APS will have equal voting rights
with holders of common stock (one vote per share) and will vote together with
holders of common stock as a single class.

     In connection with the election of the Fund's directors, holders of
outstanding shares of Preferred Stock, including any APS, voting as a separate
class, shall be entitled to elect two of the Fund's directors, and the remaining
directors will be elected by holders of common stock and Preferred Stock,
including any APS, voting as a single class. In addition, if at any time
dividends (whether or not earned or declared) on Preferred Stock,

                                       41


including any outstanding APS, shall be due and unpaid in an amount equal to two
full years' dividends thereon, and sufficient cash or specified securities shall
not have been deposited with the Auction Agent for the payment of such
dividends, then, as the sole remedy of holders of Preferred Stock, including any
outstanding APS, the number of directors constituting the Board shall be
automatically increased by the smallest number that, when added to the two
directors elected exclusively by the holders of Preferred Stock, including any
APS, as described above, would constitute a majority of the Board as so
increased by such smallest number; and at a special meeting of shareholders
which will be called and held as soon as practicable, and at all subsequent
meetings at which directors are to be elected, the holders of Preferred Stock,
including any APS, voting as a separate class, will be entitled to elect the
smallest number of additional directors that, together with the two directors
which such holders will be in any event entitled to elect, constitutes a
majority of the total number of directors of the Fund as so increased. The terms
of office of the persons who are directors at the time of that election will
continue. If the Fund thereafter shall pay, or declare and set apart for payment
in full, all dividends payable on all outstanding shares of Preferred Stock,
including any APS for all past Dividend Periods, the voting rights stated in the
preceding sentence shall cease, and the terms of office of all of the additional
directors elected by the holders of shares of Preferred Stock, including any APS
(but not of the directors with respect to whose election the holders of common
stock were entitled to vote or the two directors the holders of shares of APS
have the right to elect in any event), will terminate automatically.

     So long as any of the APS are outstanding, the Fund will not, without the
affirmative vote of a majority of the outstanding APS, determined with reference
to a "majority of outstanding voting securities" as that term is defined in
Section 2(a)(42) of the 1940 Act (voting separately as one class): (a)
authorize, create or issue any class or series of stock ranking prior to or on a
parity with the APS with respect to the payment of dividends or the distribution
of assets upon liquidation or increase the authorized amount of APS (except that
the Fund may, without the vote of the holders of APS, authorize, create or issue
classes or series of Preferred Stock ranking on a parity with the APS with
respect to the payment of dividends and the distribution of assets upon
liquidation subject to continuing compliance by the Fund with 1940 Act APS Asset
Coverage and APS Basic Maintenance Amount requirements; provided that the Fund
obtains written confirmation from Moody's (if Moody's is then rating the APS)
and S&P (if S&P is then rating the APS) that the issuance of any such additional
class or series of Preferred Stock would not impair the rating then assigned by
such rating agency to the APS), (b) amend, alter or repeal the APS Provisions,
whether by merger, consolidation or otherwise, so as to affect any preference,
right or power of such APS or the holders thereof; provided that (i) none of the
actions permitted by the exception to (a) above will be deemed to affect such
preferences, rights or powers and (ii) the authorization, creation and issuance
of classes or series of stock ranking junior to the APS with respect to the
payment of dividends and the distribution of assets upon liquidation will be
deemed to affect such preferences, rights or powers only if Moody's or S&P is
then rating the Fund and such issuance would, at the time thereof, cause the
Fund not to satisfy the 1940 Act APS Asset Coverage or the APS Basic Maintenance
Amount, or (c) file a voluntary application for relief under federal bankruptcy
law or any similar application under state law for so long as the Fund is
solvent and does not foresee becoming insolvent.

     The Board may, however, without approval of the holders of APS, amend,
alter or repeal any or all of the definitions required to be contained in the
APS Provisions by the rating agencies in the event the Fund receives written
confirmation from the appropriate rating agency that any such amendment,
alteration or repeal would not impair the ratings then assigned to the APS by
such rating agency. Unless a higher percentage is provided for under
"Description of Common Stock-Certain Anti-Takeover Provisions of the Articles of
Incorporation" in the Prospectus, the affirmative vote of the holders of a
majority of the outstanding APS, voting as a separate class, will be required to
approve any plan of reorganization (as such term is defined under the 1940 Act)
adversely affecting such shares or any action requiring a vote of security
holders under Section 13(a) of the 1940 Act including, among other things,
changes in the Fund's investment objective or changes in the investment
restrictions described as fundamental policies under "Investment Limitations."
The class vote of holders of APS described above will in each case be in
addition to a separate vote of the requisite percentage of shares of common
stock necessary to authorize the action in question. To the extent permitted by
the 1940 Act, each series of APS may vote as a separate series in certain
circumstances.

                                       42


     The foregoing voting provisions will not apply with respect to APS if at or
prior to the time when a vote is required, such APS shall have been (i) redeemed
or (ii) called for redemption and sufficient funds shall have been deposited in
trust to effect such redemption as provided under "Description of
APS-Redemption."

                                   THE AUCTION

GENERAL

     The APS Provisions provide that the Applicable Rate PER ANNUM for each
Subsequent Dividend Period after the Initial Dividend Period shall be equal to
the rate PER ANNUM that the Auction Agent advises has resulted on the Business
Day preceding the first day of such Subsequent Dividend Period from
implementation of the auction procedures ("Auction Procedures") set forth in the
APS Provisions, in which persons determine to hold or offer to sell or, based on
dividend rates bid by them, offer to purchase or sell shares of the APS. Each
periodic implementation of the Auction Procedures, which are attached as
Appendix C to this Prospectus, is referred to herein as an "auction."

     This summary is qualified by reference to the Auction Procedures set forth
in Appendix C hereto. The settlement procedures to be used with respect to
auctions for shares of the APS are set forth in Appendix D hereto.

     AUCTION AGENCY AGREEMENT. The Fund will enter into an amendment to its
existing agreement (as so amended, the "Auction Agency Agreement") with respect
to its APS Series A shares and APS Series B shares to make it applicable to its
APS Series C shares. The Auction Agency Agreement is between the Fund and
Deutsche Bank Trust Company Americas (together with any successor bank or trust
company or other entity entering into a similar agreement with the Fund,
"Auction Agent") and provides, among other things, that the Auction Agent will
follow the Auction Procedures for purposes of determining the Applicable Rate
for the APS so long as the Applicable Rate is to be based on the results of an
auction.

     BROKER-DEALER AGREEMENTS. Each auction requires the participation of one or
more broker-dealers. The Auction Agent will enter into agreements (or amendments
to existing agreements) with UBS Financial Services Inc. and may enter into
similar agreements (or amendments) (collectively, the "Broker-Dealer
Agreements") with one or more additional broker-dealers (collectively the
"Broker-Dealers") selected by the Fund, which provide for the participation of
Broker-Dealers in auctions for APS Series C shares. See "Broker-Dealers" below.

     MASTER PURCHASER'S LETTER. Each prospective purchaser of shares of the APS
or its Broker-Dealer will be required to sign and deliver to the Auction Agent,
as a condition to such purchaser's purchasing shares of the APS in any auction
or otherwise, a letter, the form of which is attached to this Prospectus as
Appendix E (the "Master Purchaser's Letter"), in which such prospective
purchaser or its Broker-Dealer will agree, among other things:

          (a)     to participate in auctions for shares of the APS on the terms
     set forth in Appendix C hereto;

          (b)     to sell, transfer or otherwise dispose of shares of the APS
     only in whole shares and only pursuant to a bid or a sell order (as defined
     under "Orders by Existing Holders and Potential Holders" below) in an
     auction, or to or through a Broker-Dealer or to a person that has delivered
     a signed Master Purchaser's Letter to the Auction Agent, provided that in
     the case of any transfer other than those pursuant to auctions, the
     Existing Holder (as defined below) of the shares so transferred, its Agent
     Member (as defined below) or its Broker-Dealer advises the Auction Agent of
     such transfer; and

          (c)     to have the ownership of the shares of the APS as to which
     such purchaser or its Broker-Dealer is the Existing Holder maintained in
     book entry form by ______________ together with any successor securities
     depository selected by the Fund, the "Securities Depository") for the
     account of its agent member (the "Agent Member") of such Securities
     Depository, which in turn will maintain records of such purchaser's
     beneficial ownership, and to authorize such Agent Member to disclose to the
     Auction Agent such information with respect to such purchaser's beneficial
     ownership as the Auction Agent may request.

                                       43


     Each prospective purchaser should ask its Broker-Dealer whether such
prospective purchaser should sign a Master Purchaser's Letter. If the
Broker-Dealer submits orders for such prospective purchaser listing the
Broker-Dealer as the Existing Holder or the Potential Holder, a Master
Purchaser's Letter signed by such prospective purchaser may not be required.

     AN EXECUTION COPY OF THE MASTER PURCHASER'S LETTER IS INCLUDED INSIDE THE
BACK COVER OF THE PROSPECTUS. EXECUTION BY A PROSPECTIVE PURCHASER OR ITS
BROKER-DEALER OF A MASTER PURCHASER'S LETTER IS NOT A COMMITMENT TO PURCHASE
SHARES OF THE APS IN THE OFFERING BEING MADE BY THE PROSPECTUS OR IN ANY
AUCTION, BUT IS A CONDITION PRECEDENT TO SUCH PURCHASER'S PURCHASING SHARES OF
THE APS. IN ADDITION, ACCEPTANCE OF A MASTER PURCHASER'S LETTER IS NOT A
GUARANTEE THAT SHARES OF THE APS WILL BE AVAILABLE FOR PURCHASE.

     As used herein, "Existing Holder" means a person who has signed, or on
whose behalf a Broker-Dealer has signed, a Master Purchaser's Letter and is
listed as the beneficial owner of such shares of APS in the records of the
Auction Agent. The Auction Agent may rely upon, as evidence of the identities of
the Existing Holders, a list of the initial owners of the shares of the APS
provided by the Fund, the results of auctions and notices from any Existing
Holder, the Agent Member of such Existing Holder or the Broker-Dealer of such
Existing Holder with respect to transfers described in the next sentence. The
Auction Agent will be required to register a transfer of shares of the APS from
an Existing Holder to another person only if such transfer is made to a person
that has delivered a signed Master Purchaser's Letter to the Auction Agent and
if (i) such transfer is pursuant to an auction; or (ii) the Auction Agent has
been notified in writing (A) by such Existing Holder, the Agent Member of such
Existing Holder or the Broker-Dealer of such Existing Holder of such transfer or
(B) by the Broker-Dealer of any person that purchased or sold shares of the APS
in an auction of the failure of such APS to be transferred as a result of such
auction. The Auction Agent is not required to accept any such notice for an
auction unless it is received by the Auction Agent by 3:00 P.M., New York time,
on the Business Day preceding such auction.

     The Auction Agent is not required to accept the Master Purchaser's Letter
of any Potential Holder who wishes to submit a bid for the first time in an
auction or of any Potential Holder or Existing Holder who wishes to amend its
Master Purchaser's Letter unless such Letter or amendment is received by the
Auction Agent by 3:00 PM., Eastern time, on the Business Day preceding such
auction.

     SECURITIES DEPOSITORY. ________________________________ will act as the
Securities Depository for the Agent Members with respect to Shares of APS. One
certificate for all of the shares of the APS Series C offered hereby will be
registered in the name of _______, as nominee of the Securities Depository. Such
certificate will bear a legend to the effect that such certificate is issued
subject to the provisions restricting transfers of APS contained in the APS
Provisions and the Master Purchaser's Letters. The Fund will also issue
stop-transfer instructions to the transfer agent for the APS. [Nominee] will be
the holder of record of all shares of the APS and beneficial owners of shares of
the APS will not receive certificates representing their ownership interest in
such shares.

     _____ performs services for its participants (including the Agent Members),
some of whom (and/or their representatives) own _____. _____ maintains lists of
its participants and will maintain the positions (ownership interests) held by
each Agent Member in APS, whether for its own account or as a nominee for
another person.

AUCTION DATES; ADVANCE NOTICE OF ALLOCATION OF TAXABLE INCOME

     An auction to determine the Applicable Rate with respect to the APS for
each Rate Period after the Initial Dividend Period thereof will be held on the
first Business Day preceding the first day of such Rate Period (the date of each
auction being referred to herein as an "Auction Date"). The Auction Date and the
first day of the related Rate Period (also a Dividend Payment Date) must be
Business Days but need not be consecutive days. See "Description of
APS-Dividends" for information concerning the circumstances under which the
first day of a Rate Period or the Auction Date, or both, may be moved to a date
other than such specified days.

     In normal circumstances, whenever the Fund intends to include any net
capital gains or other income that is taxable for federal income tax purposes in
any dividend on the APS, the Fund may notify the Auction Agent of the amount to
be so included 15 days prior to the Auction Date on which the Applicable Rate
for such

                                       44


dividend is to be established. Whenever the Auction Agent receives such notice
from the Fund, it will in turn notify each Broker-Dealer, who, on or prior to
such Auction Date, in accordance with its Broker-Dealer Agreement, will notify
its Existing Holders and Potential Holders believed by it to be interested in
submitting an order in the auction to be held on such Auction Date.

ORDERS BY EXISTING HOLDERS AND POTENTIAL HOLDERS

     Prior to the Submission Deadline (as defined under "Submission of Orders by
Broker-Dealers to Auction Agent" below) on each Auction Date:

          (a)     each Existing Holder may submit to a Broker-Dealer by
     telephone or otherwise a:

                  (i)     "hold order"--indicating the number of outstanding
          shares, if any, of the APS that such Existing Holder desires to
          continue to hold without regard to the Applicable Rate for the next
          Rate Period;

                  (ii)    "bid"--indicating the number of outstanding shares, if
          any, of the APS that such Existing Holder desires to sell if the
          Applicable Rates for the next Rate Period shall be less than the rate
          PER ANNUM then specified by such Existing Holder; and/or

                  (iii)   "sell order"--indicating the number of outstanding
          shares, if any, of the APS that such Existing Holder offers to sell
          without regard to the Applicable Rate for the next Rate Period;

          and

          (b)     Broker-Dealers shall contact prospective purchasers of shares
     of the APS (each such prospective purchaser is herein referred to as a
     "Potential Holder," and the term Potential Holder includes an Existing
     Holder with respect to an offer by such Existing Holder to purchase
     additional shares of the APS) by telephone or otherwise to determine
     whether such Potential Holders desire to submit bids, in which Potential
     Holders will indicate the number of shares of the APS that they offer to
     purchase if the Applicable Rate for the next Rate Period is not less than
     the rate PER ANNUM specified in such bids.

     The communication to a Broker-Dealer of the foregoing information is herein
referred to as an "order." An Existing Holder or a Potential Holder placing an
order is herein referred to as a "bidder" and collectively as "bidders."

     An Existing Holder may submit different types of orders in an auction with
respect to shares of APS then held by such Existing Holder. An Existing Holder
that offers to purchase additional shares of the APS is, for purposes of such
offer, treated as a Potential Holder. For information concerning the priority
given to different types of orders placed by Existing Holders, see "Submission
of Orders by Broker-Dealers to Auction Agent" below.

     Any bid specifying a rate higher than the Maximum Rate (as defined below)
will (i) be treated as a sell order if submitted by an Existing Holder and (ii)
not be accepted if submitted by a Potential Holder. Accordingly, the auction
Procedures establish the Maximum Rate as a maximum rate PER ANNUM that can
result from an auction. See "Determination of sufficient clearing bids, Winning
Bid Rate and Applicable Rate" and "Acceptance and Rejection of Submitted Bids
and Submitted Sell Orders and Allocation of Shares" below.

     As used herein, "Maximum Rate," when used with respect to shares of the APS
on an Auction Date, means:

          (i)     in the case of any Auction Date which is not the Auction Date
     immediately prior to the first day of any proposed Special Dividend Period
     of more than 28 days, the product of (1) the Reference Rate on such Auction
     Date for the next Rate Period and (2) the Applicable Percentage on such
     Auction Date, unless the APS has or had a Special Dividend Period (other
     than a Special Dividend Period of 28 days or less) and an auction at which
     sufficient clearing bids existed has not yet occurred for a Minimum
     Dividend Period after such Special Dividend Period, in which case the
     higher of:

                  (A)     the dividend rate on the APS for the then-ending Rate
          Period, and

                                       45


                  (B)     the product of (x) the higher of (I) the 'AA'
          Composite Commercial Paper Rate on such Auction Date for the
          then-ending Rate Period, if such Rate Period is less than one year, or
          the Treasury Rate on such Auction Date for such Rate Period, if such
          Rate Period is one year or greater, and (II) the "AA" Composite
          Commercial Paper Rate on such Auction Date for such Special Dividend
          Period, if such Special Dividend Period is less than one year, or the
          Treasury Rate on such Auction Date for such Special Dividend Period,
          if such Special Dividend Period is one year or greater and (y) the
          Applicable Percentage on such Auction Date;

          or

          (ii)    in the case of any Auction Date which is the Auction Date
     immediately prior to the first day of any proposed Special Dividend Period
     of more than 28 days, the product of (1) the highest of (x) the Reference
     Rate on such Auction Date for the then-ending Rate Period, if such Rate
     Period is less than one year, or the Treasury Rate on such Auction Date for
     such Rate Period, if such Rate Period is one year or greater, (y) the
     Reference Rate on such Auction Date for the Special Dividend Period for
     which the auction is being held, if such Special Dividend Period is less
     than one year, or the Treasury Rate on such Auction Date for the Special
     Dividend Period for which the auction is being held, if such Special
     Dividend Period is one year or greater; and (z) the Reference Rate on such
     Auction Date for the Minimum Dividend Period and (2) the Applicable
     Percentage on such Auction Date.

     The Reference Rate is, with respect to any Rate Period of less than one
year, the higher of (i) the "AA" Composite Commercial Paper Rate and (ii) the
Taxable Equivalent of the Short-Term Municipal Bond Rate. The applicable "AA"
Composite Commercial Paper Rates and Treasury Rates will be the rates announced
on such Auction Date for the Business Day immediately prior to such Auction
Date.

     The "Applicable Percentage," for the APS on any Auction Date, will be a
percentage, determined as set forth below, based on the prevailing rating of
shares of the APS in effect at the close of business on the Business Day next
preceding such Auction Date;



                  PREVAILING RATING             APPLICABLE PERCENTAGE
                  -----------------             ---------------------
                                             
                  "aa3"/AA- or higher           110%
                  "a3"/A-                       125%
                  "baa3"/BBB                    150%
                  ba3"/BB-                      200%
                  Below "ba3"/BB-               250%


provided, however, that in the event the Fund has notified the Auction Agent of
its intent to allocate income taxable for federal income tax purposes to the APS
prior to the auction establishing the Applicable Rate for such shares, the
Applicable Percentage in the foregoing table shall be divided by the quantity 1
minus the Marginal Tax Rate; provided that the Applicable Percentage shall be
divided in the foregoing manner only to the extent of the portion of the
dividend on the APS for such Rate Period that represents the allocation of
taxable income to such APS. If the APS are rated by only one rating agency, such
rating will be the prevailing rating.

     For purposes of this determination, the "prevailing rating" of shares of
the APS shall be (i) "Aaa/AA- or higher if shares of the APS have a rating of
"Aaa" or better by Moody's and AA- or better by S&P or the equivalent of such
ratings by such agencies or a substitute rating agency or substitute rating
agencies selected as provided below, (ii) if not "Aaa/AA- or higher, then
"a3"/A- if the shares of the APS have a rating of "a3" or better by Moody's and
A- or better by S&P or the equivalent of such ratings by such agencies or a
substitute rating agency or substitute rating agencies selected as provided
below, (iii) if not "Aaa/AA- or higher or "a3"/ A-, then "baa/BBB- if the shares
of the APS have a rating of "baa" or better by Moody's and BBB- or better by S&P
or the equivalent of such ratings by such agencies or a substitute rating agency
or substitute rating agencies selected as provided below, (iv) if not "Aaa/AA-
or higher, "a3"/A- or "baa3"/BBB-, then "ba3"/ BB- if the shares of the APS have
a rating of "ba3" or better by Moody's and BB- or better by S&P or the
equivalent of such ratings by such agencies or substitute rating agency or
substitute rating agencies selected as provided below, and (v) if not "aa3"/AA-
or higher, "a3"/A- "baa3"/BBB-, or "ba3"/BB-, then below "ba3"/BB-; provided,
however, that if the APS are rated by only one rating agency, the prevailing
rating shall be determined without reference to the rating of any other rating
agency. The Fund will take all reasonable action necessary to enable either S&P
or Moody's to provide a rating for the APS. If neither S&P nor Moody's shall
make such a

                                       46


rating available, [UBS Financial Services Inc.] or __________ or their
successors as Broker-Dealers shall select at least one nationally recognized
statistical rating organization (as that term is used in the rules and
regulations of the SEC under the Securities Exchange Act of 1934 ("1934 Act") to
act as a substitute rating agency in respect of the APS, and the Fund shall take
all reasonable action to enable such rating agency to provide a rating for
shares of such series.

     The Master Purchaser's Letter to be signed by each Existing Holder and each
Potential Holder or its Broker-Dealer provides that (i) a sell order placed by
an Existing Holder shall constitute an irrevocable offer to sell the shares of
the APS subject thereto, (ii) a bid placed by an Existing Holder shall
constitute an irrevocable offer to sell the shares of the APS subject thereto if
the rate determined in the auction is less than the rate specified in such bid,
and (iii) a bid placed by a Potential Holder shall constitute an irrevocable
offer to purchase the number of shares of the APS specified in such bid if the
rate determined in the auction is equal to or greater than the rate specified in
the bid. The number of shares purchased or sold may be subject to proration
procedures. See "Acceptance and Rejection of Submitted Bids and Submitted Sell
Orders and Allocation of Shares" below. Each purchase or sale shall be made for
settlement on the Business Day next succeeding the Auction Date at a price per
share equal to $50,000. See "The Auction--Notification of Results; Settlement"
below. The Auction Agent is entitled to rely upon the terms of any sell order
submitted to it by a Broker-Dealer.

     With respect to an auction preceding a Rate Period of less than 90 days, if
a sell order or sell orders covering all of the outstanding shares of the APS
held by any Existing Holder are not submitted to the Auction Agent prior to the
Submission Deadline, either because a Broker-Dealer failed to contact such
Existing Holder or otherwise, the Auction Agent shall deem a hold or sell order
to have been submitted on behalf of such Existing Holder covering the number of
outstanding shares of the APS held by such Existing Holder and not subject to
sell orders submitted to the Auction Agent. With respect to an auction preceding
a Rate Period of 90 days or greater, a sell order will be deemed to have been
submitted on behalf of an Existing Holder with respect to any shares held by
such Existing Holder for which a sell order is not submitted on behalf of such
Existing Holder for any reason, including the failure of a Broker-Dealer to
submit such Existing Holder's sell order to the Auction Agent.

     Neither the Fund nor any affiliate thereof may submit an sell order in any
auction, except that any Broker-Dealer that is an affiliate of the Fund may
submit sell orders in an auction, but only if such sell orders are not for its
own account.

SUBMISSION OF ORDERS BY BROKER-DEALERS TO AUCTION AGENT

     Prior to 1:30 PM, Eastern time, on each Auction Date, or such other time on
the Auction Date specified by the Auction Agent (the "Submission Deadline"),
each Broker-Dealer will submit to the Auction Agent in writing all sell orders
obtained by it for the auction to be conducted on such Sell Order Date. Any sell
order submitted by a Broker-Dealer to the Auction Agent prior to the Submission
Deadline on any Auction Date shall be irrevocable.

     If any rate specified in any bid contains more than three figures to the
right of the decimal point, the Auction Agent will round such rate to the next
highest one-thousandth (.001) of 1%.

     If any Existing Holder submits through a Broker-Dealer to the Auction Agent
one or more sell orders covering in the aggregate more than the number of
outstanding shares of the APS subject to such auction held by such Existing
Holder, such sell orders will be considered valid in the following order of
priority:

          (a)     all hold orders will be considered valid, but only up to and
     including in the aggregate the number of shares of the APS held by such
     Existing Holder;

          (b)     (i) any bid will be considered valid up to and including the
     excess of the number of outstanding shares of the APS held by such Existing
     Holder over the number of shares of the APS subject to any hold orders
     referred to in clause (a) above;

                  (ii) subject to sub-clause (i), if more than one bid with the
     same rate is submitted on behalf of such Existing Holder and the number of
     shares of the APS subject to such bids is greater than such excess, such
     bids will be considered valid up to and including the amount of such
     excess, and the

                                       47


     number of shares of the APS subject to each bid with the same rate will be
     reduced pro rata to cover the number of shares of the APS equal to such
     excess;

                  (iii) subject to sub-clauses (i) and (ii), if more than one
     bid with different rates is submitted on behalf of such Existing Holder,
     such bids shall be considered valid in the ascending order of their
     respective rates up to and including the amount of such excess; and

                  (iv) in any such event, the number, if any, of such shares
     subject to bids not valid under this clause (b) will be treated as the
     subject of a bid by a Potential Holder at the rate specified therein; and

          (c)     all sell orders will be considered valid up to and including
     the excess of the number of outstanding shares of the APS held by such
     Existing Holder over the sum of shares of the APS subject to valid hold
     orders referred to in clause (a) above and valid bids by such Existing
     Holder referred to in clause (b) above.

     If more than one bid is submitted on behalf of any Potential Holder, each
bid submitted will be a separate bid with the rate and number of shares therein
specified.

DETERMINATION OF SUFFICIENT CLEARING BIDS, WINNING BID RATE AND APPLICABLE RATE

     Not earlier than the Submission Deadline on each Auction Date, the Auction
Agent will assemble all valid orders submitted or deemed submitted to it by the
Broker-Dealers (each such hold order, bid or sell order as submitted or deemed
submitted by a Broker-Dealer being herein referred to as a "submitted hold
order," a "submitted bid" or a "submitted sell order," as the case may be, or as
a "submitted order") and will determine the excess of the number of outstanding
shares of the APS over the number of outstanding shares of the APS subject to
submitted hold orders (such excess being herein referred to as the "Available
APS") and whether sufficient clearing bids have been made in the auction.
"Sufficient clearing bids" will have been made if the number of outstanding
shares of the APS that are the subject of submitted bids by Potential Holders
specifying rates not higher than the Maximum Rate equals or exceeds the number
of outstanding shares that are the subject of submitted sell orders (including
the number of shares of the APS subject to bids by Existing Holders specifying
rates higher than the Maximum Rate).

     If sufficient clearing bids have been made, the Auction Agent will
determine the lowest rate specified in the submitted bids (the "Winning Bid
Rate") which, taking into account the rates in the submitted bids of Existing
Holders, would result in Existing Holders continuing to hold an aggregate number
of outstanding shares of the APS which, when added to the number of outstanding
shares of the APS to be purchased by Potential Holders, based on the rates in
their submitted bids, would equal not less than the Available APS. In such
event, the Winning Bid Rate will be the Applicable Rate for the next Rate Period
for all shares of the APS.

     If sufficient clearing bids have not been made (other than because all of
the outstanding shares of the APS are subject to submitted hold orders), the
Applicable Rate for the next Rate Period, which shall be a Minimum Dividend
Period, for all shares of the APS will be equal to the Maximum Rate. If
sufficient clearing bids have not been made, Existing Holders that have
submitted sell orders may not be able to sell in the auction all shares of the
APS subject to such submitted sell orders but will continue to own shares of the
APS for the next Rate Period, dividends for which may include taxable income.
See "The Auction--Auction Dates; Advance Notice of Allocation of Taxable Income"
above and "The Auction--Acceptance and Rejection of Submitted Bids and Submitted
Sell Orders and Allocation of Shares" below.

     If all of the outstanding shares of the APS are subject to submitted hold
orders, the Applicable Rate for the next Rate Period for all shares of such
series of APS will be the product of (i) (1) the Reference Rate on such Auction
Date for such Rate Period, if such Rate Period is less than one year or (2) the
Treasury Rate on such Auction Date for such Rate Period, if such Rate Period is
one year or greater and (ii) 1 minus the Marginal Tax Rate; provided, however,
that if the Fund has notified the auction Agent of its intent to allocate to
shares of the APS in such Rate Period any net capital gains or other income that
is taxable for federal income tax purposes, the Applicable Rate in respect of
that portion of the dividend on the APS for such Rate Period that represents the
allocation of net capital gains or other income that is taxable for federal
income tax purposes will be the rate described in the preceding clause (i) (1)
or (2), as applicable, without being multiplied by the factor set forth in

                                       48


the preceding clause (ii). In calculating the Reference Rate and the Treasury
Rate for such purpose, the rates used will be the rates or yields specified in
the applicable definitions of "Reference Rate" and "Treasury Rate" set forth
under "Description of APS--Dividends--Determination of Dividend Rate."

ACCEPTANCE AND REJECTION OF SUBMITTED BIDS AND SUBMITTED SELL ORDERS AND
ALLOCATION OF SHARES

     Based on the determinations made under "Determination of sufficient
clearing bids, Winning Bid Rate and Applicable Rate" above and, subject to the
discretion of the Auction Agent to round and allocate certain shares as
described below, submitted bids and submitted sell orders will be accepted or
rejected in the order of priority set forth in the Auction Procedures, with the
result that Existing Holders and Potential Holders of the APS will sell,
continue to hold and/or purchase shares of the APS as set forth below. Existing
Holders that submitted or were deemed to have submitted hold orders will
continue to hold the APS subject to such hold orders.

          If sufficient clearing bids have been made:

          (a)     each Existing Holder that placed a submitted sell order or
     submitted bid specifying any rate higher than the Winning Bid Rate will
     sell the outstanding shares of the APS subject to such submitted sell order
     or submitted bid;

          (b)     each Existing Holder that placed a submitted bid specifying a
     rate lower than the Winning Bid Rate will continue to hold the outstanding
     shares of the APS subject to such submitted bid;

          (c)     each Potential Holder that placed a submitted bid specifying a
     rate lower than the Winning Bid Rate will purchase the number of
     outstanding shares of the APS subject to such submitted bid;

          (d)     each Existing Holder that placed a submitted bid specifying a
     rate equal to the Winning Bid Rate will continue to hold the shares the APS
     subject to such submitted bid, unless the number of outstanding shares of
     the APS subject to all such submitted bids is greater than the number of
     shares of the APS in excess of the Available APS over the number of shares
     of the APS accounted for in clauses (b) and (c) above, in which event each
     Existing Holder with such a submitted bid will continue to hold a number of
     outstanding shares of the APS subject to such submitted bid determined on a
     pro rata basis based on the number of outstanding shares of the APS subject
     to all such submitted bids by such Existing Holders; and

          (e)     each Potential Holder that placed a submitted bid specifying a
     rate equal to the Winning Bid Rate will purchase any shares of the
     Available APS not accounted for in clauses (b) through (d) above on a pro
     rata basis based on the outstanding shares of the APS subject to all such
     submitted bids.

     If sufficient clearing bids have not been made (unless this results because
all outstanding shares of the APS are subject to submitted hold orders):

          (a)     each Existing Holder that placed a submitted bid specifying a
     rate equal to or lower than the Maximum Rate will continue to hold the
     outstanding shares of the APS subject to such submitted bid;

          (b)     each Potential Holder that placed a submitted bid specifying a
     rate equal to or lower than the Maximum Rate will purchase the number of
     outstanding shares of the APS subject to such submitted bid; and

          (c)     each Existing Holder that placed a submitted bid specifying a
     rate higher than the Maximum Rate or a submitted sell order will sell a
     number of shares of the APS determined on a pro rata basis based on the
     number of outstanding shares of APS subject to all such submitted bids and
     submitted sell orders.

     If, as a result of the pro rata allocation described in clause (d) or (e)
of the second preceding paragraph or clause (c) of the next preceding paragraph,
any Existing Holder would be entitled or required to sell, or any Potential
Holder would be entitled or required to purchase, a fraction of a share of APS,
the Auction Agent will, in such manner as, in its sole discretion, it will
determine, round up or down to the nearest whole share the number of APS being
sold or purchased on such Auction Date so that the number of shares sold or
purchased by

                                       49


each Existing Holder or Potential Holder will be whole shares of APS. If as a
result of the pro rata allocation described in clause (e) of the second
preceding paragraph, any Potential Holder would be entitled or required to
purchase less than a whole share of APS, the Auction Agent will, in such manner
as, in its sole discretion, it will determine, allocate APS for purchase among
Potential Holders so that only whole shares of APS are purchased by any such
Potential Holder, even if such allocation results in one or more of such
Potential Holders not purchasing APS.

NOTIFICATION OF RESULTS; SETTLEMENT

     The Auction Agent will advise each Broker-Dealer that submitted an order of
the Applicable Rate for the next Rate Period and, if the order was a bid or sell
order, whether such bid or sell order was accepted or rejected, in whole or in
part, by telephone by approximately 3:00 PM., Eastern time, on each Auction
Date. Each Broker-Dealer that submitted an order on behalf of a bidder will then
advise such bidder of the Applicable Rate for the next Rate Period and, if such
order was a bid or a sell order, whether such bid or sell order was accepted or
rejected, in whole or in part, will confirm purchases and sales with each bidder
purchasing or selling APS as a result of the auction and will advise each bidder
purchasing or selling APS as a result of the auction to give instructions to its
Agent Member of the Securities Depository to pay the purchase price against
delivery of such shares or to deliver such shares against payment therefor, as
appropriate. The Auction Agent will record each transfer of APS on the registry
of Existing Holders to be maintained by the Auction Agent. See "The
Auction--General" above.

     In accordance with the Securities Depository's normal procedures, on the
Business Day after the Auction Date, the transactions described above will be
executed through the Securities Depository and the accounts of the respective
Agent Members at the Securities Depository will be debited and credited and
shares delivered as necessary to effect the purchases and sales of APS as
determined in the auction. Purchasers will make payment through their Agent
Members in same-day funds to the Securities Depository against delivery through
their Agent Members; the Securities Depository will make payment in accordance
with its normal procedures, which now provide for payment against delivery by
their Agent Members in same-day funds.

     If any Existing Holder selling APS in an auction fails to deliver such
shares, the Broker-Dealer of any person that was to have purchased APS in such
auction may deliver to such person a number of whole shares of APS that is less
than the number of shares that otherwise was to be purchased by such person. In
such event, the number of APS to be so delivered shall be determined by such
Broker-Dealer. Delivery of such lesser number of shares shall constitute good
delivery.

CONCERNING THE AUCTION AGENT

     The Auction Agent is acting as agent for the Fund in connection with
auctions. In the absence of bad faith or negligence on its part, the Auction
Agent will not be liable for any action taken, suffered, or omitted or for any
error of judgment made by it in the performance of its duties under the Auction
Agency Agreement and will not be liable for any error of judgment made in good
faith unless the Auction Agent will have been negligent in ascertaining the
pertinent facts.

     The Auction Agent may terminate the Auction Agency Agreement upon notice to
the Fund on a date no earlier than 100 days after such notice. If the Auction
Agent should resign, the Fund will use its best efforts to enter into an
agreement with a successor Auction Agent containing substantially the same terms
and conditions as the Auction Agency Agreement. The Fund may remove the Auction
Agent provided that prior to such removal the Fund shall have entered into such
an agreement with a successor Auction Agent.

BROKER-DEALERS

     The Auction Agent after each auction for APS will pay to each
Broker-Dealer, from funds provided by the Fund, a service charge at the annual
rate of 0.25 of 1% in the case of any auction immediately preceding a Rate
Period of less than one year , or a percentage agreed to by the Fund and the
Broker-Dealers in the case of any auction immediately preceding a Rate Period of
one year or longer, of the purchase price of APS placed by such Broker-Dealer at
such auction. For the purposes of the preceding sentence, APS will be placed by
a Broker-Dealer if such shares were (i) the subject of hold orders deemed to
have been made by Existing Holders and were acquired by such Existing Holders
through such Broker-Dealer or (ii) the subject of an order submitted

                                       50


by such Broker-Dealer that is (A) a submitted bid of an Existing Holder that
resulted in such Existing Holder continuing to hold such shares as a result of
the auction or (B) a submitted bid of a Potential Holder that resulted in such
Potential Holder purchasing such shares as a result of the auction or (C) a
valid hold order.

     The Fund may request the Auction Agent to terminate one or more
Broker-Dealer Agreements at any time, provided that at least one Broker-Dealer
Agreement is in effect after such termination.

     The Broker-Dealer Agreements provide that a Broker-Dealer (other than an
affiliate of the Fund) may submit orders in auctions for its own account, unless
the Fund notifies all Broker-Dealers that they may no longer do so, in which
case Broker-Dealers may continue to submit hold orders and sell orders for their
own accounts. Any Broker-Dealer that is an affiliate of the Fund may submit
orders in auctions, but only if such orders are not for its own account. If a
Broker-Dealer submits an order for its own account in any auction, it might have
an advantage over other bidders because it would have knowledge of orders placed
through it in that auction; such Broker-Dealer, however, would not have
knowledge of orders submitted by other Broker-Dealers in that auction.

     The Broker-Dealers may maintain a secondary trading market in the APS
outside of auctions. They have no obligation to do so, however, and there can be
no assurance that a secondary market for the APS will develop or, if it does
develop, that it will provide holders with liquidity of investment. The APS will
not be registered on any stock exchange or on the National Association of
Securities Dealers Automated Quotations system.

                             ADDITIONAL INFORMATION

COMMON STOCK REPURCHASES AND TENDER OFFERS

     In recognition of the possibility that the common stock might trade at a
discount to net asset value and that any such discount may not be in the
interest of common shareholders, the Board has determined that it will consider
taking action to attempt to reduce or eliminate any discount. To that end, the
Board may, in consultation with UBS Global AM, from time to time consider action
either to repurchase shares of the common stock in the open market or to make a
tender offer for shares of the common stock at their net asset value. The Board
currently intends at least annually to consider making such open market
repurchases or tender offers and at such time may consider such factors as the
market price of the common stock, the net asset value of the common stock, the
liquidity of the assets of the Fund, whether such transactions would impair the
Fund's status as a regulated investment company or result in a failure to comply
with applicable asset coverage requirements, general economic conditions and
such other events or conditions that may have a material effect on the Fund's
ability to consummate such transactions. The Board may at any time, however,
decide that the Fund should not repurchase shares or make a tender offer. Common
stock will not be repurchased unless after such repurchase the Fund would
continue to satisfy the 1940 Act APS Asset Coverage and the APS Basic
Maintenance Amount.

     Subject to the Fund's investment restrictions with respect to borrowings
and subject to the Fund's compliance with the 1940 Act, the Fund may incur debt
to finance common stock repurchases or tender offers or for investment purposes.
See "Investment Limitations." Should the Fund borrow for these or any other
purposes, it would be required to pay when due the interest obligation on any
debt incurred by it before it would be able to pay dividends on the APS, and it
is likely that the Fund would be required to pay the principal amount of any
such debt prior to meeting the liquidation preference of the APS. Because the
interest expense on borrowings by the Fund will reduce the Fund's net investment
income available to pay dividends on the APS, borrowing may impair the Fund's
ability to pay such dividends. This risk is heightened in the event the Fund
incurs variable rate debt, the interest rate on which may increase with
increases in prevailing market rates.

     There is no assurance that repurchases or tender offers will result in the
common stock trading at a price that is equal or close to its net asset value
per share. The market price of shares of the common stock will be determined by,
among other things, the relative demand for and supply of such shares in the
market, the Fund's investment performance, the Fund's dividends and yield and
investor perception of the Fund's overall attractiveness as an investment as
compared with other investment alternatives. Nevertheless, the fact that the
common stock may be the subject of tender offers at net asset value from time to
time may reduce the spread that might otherwise exist between the market price
of the common stock and net asset value per share. In the

                                       51


opinion of UBS Global AM, sellers may be less inclined to accept a significant
discount if they have a reasonable expectation of being able to recover net
asset value in conjunction with a possible tender offer.

     Although the Board believes that common stock repurchases and tender offers
generally would have a favorable effect on the market price of the common stock,
it should be recognized that the Fund's acquisition of shares of the common
stock would decrease the Fund's total assets and therefore have the effect of
increasing the Fund's expense ratio and decreasing the asset coverage with
respect to any outstanding Preferred Stock. Because of the nature of the Fund's
investment objective, policies and portfolio, under current market conditions
UBS Global AM anticipates that repurchases and tender offers generally should
not have a material, adverse effect on the Fund's investment performance and
that UBS Global AM generally should not have any material difficulty in
disposing of portfolio securities in order to consummate common stock
repurchases and tender offers; however, this may not always be the case.

     Even if such a tender offer has been made, it will be the Board's announced
policy, which may be changed by the Board, not to accept tenders or effect
repurchases (or, if a tender offer has not been made, not to initiate a tender
offer) if: (1) such transactions, if consummated, would (a) result in the
delisting of the common stock from the NYSE (the NYSE having advised the Fund
that it would consider delisting if the aggregate market value of the
outstanding shares is less than $5,000,000, the number of publicly held shares
falls below 600,000 or the number of round-lot holders falls below 1,200), (b)
impair the Fund's status as a regulated investment company under the Internal
Revenue Code (which would eliminate the Fund's eligibility to deduct dividends
paid to shareholders, thus causing the Fund's taxable income to be fully taxed
at the corporate level in addition to the taxation of shareholders upon
dividends received from the Fund), or (c) result in a failure to comply with the
1940 Act APS Asset Coverage or the APS Basic Maintenance Amount or both (so long
as the same are applicable); (2) the Fund would not be able to liquidate
portfolio securities in an orderly manner and consistent with the Fund's
investment objective and policies in order to repurchase its shares or (3) there
is, in the Board's judgment, any (a) material legal action or proceeding
instituted or threatened challenging such transactions or otherwise materially
adversely affecting the Fund, (b) suspension of trading or limitation on prices
of securities generally on the NYSE or any other exchange on which portfolio
securities of the Fund are traded, (c) declaration of a trading moratorium by
federal or state authorities or any suspension of payment by banks in the United
States, New York State or any state in which the Fund invests, (d) limitation
affecting the Fund or the issuers of its portfolio securities imposed by federal
or state authorities on the extension of credit by lending institutions, (e)
commencement of war, armed hostilities or other international or national
calamity directly or indirectly involving the United States or (f) other event
or condition that would have a material adverse effect on the Fund or its
shareholders if shares were repurchased. The Board may modify these conditions
in light of experience.

     Any tender offer made by the Fund for shares of the common stock generally
would be at a price equal to the net asset value of the shares of common stock
on a date subsequent to the Fund's receipt of all tenders. Each offer would be
made, and the common shareholders would be notified, in accordance with the
requirements of the 1934 Act and the 1940 Act, either by publication or mailing
or both. Each offering document would contain such information as is prescribed
by such laws and the rules and regulations promulgated thereunder. Each person
tendering shares of common stock would pay to the Fund's transfer agent a
service charge to help defray certain costs, including the processing of tender
forms, effecting payment, postage and handling. Any such service charge would be
paid directly by the tendering shareholder and would not be deducted from the
proceeds of the purchase. The Fund's transfer agent would receive the fee as an
offset to these costs. The Fund expects that the costs of effecting a tender
offer would exceed the aggregate of all service charges received from those who
tender their shares of common stock. Costs associated with the tender offer
would be charged against capital.

     Tendered shares of common stock that have been accepted and purchased by
the Fund will be held in the Fund's treasury until retired by the Board. If
treasury shares are retired, common stock issued and outstanding and capital in
excess of par will be reduced. If tendered shares are not retired, the Fund may
hold, sell or otherwise dispose of the shares for any lawful corporate purpose
as determined by the Board.

                                       52


CONVERSION TO OPEN-END INVESTMENT COMPANY

     The Board will consider from time to time whether it would be in the best
interests of the Fund and its common shareholders to convert the Fund to an
open-end investment company. If the Board determines that such a conversion
would be in the best interests of the Fund and its common shareholders and is
consistent with the 1940 Act, the Board will submit to the Fund's shareholders,
at the next succeeding annual or special meeting, a proposal to amend the Fund's
Articles of Incorporation to so convert the Fund. Such amendment would provide
that, upon its adoption by the holders of at least a majority of the Fund's
outstanding Shares entitled to vote thereon, the Fund will convert from a
closed-end to an open-end investment company. If the Fund converted to an
open-end investment company, it would be able to continuously issue and offer
for sale shares of the common stock, and each such share could be presented to
the Fund at the option of the holder thereof for redemption at a price based on
the then current net asset value per share. In such event, the Fund could be
required to liquidate portfolio securities to meet requests for redemption, the
common stock would no longer be listed on the NYSE and certain investment
policies of the Fund would require amendment. In addition, conversion to an
open-end investment company would require that the Fund redeem any outstanding
shares of Preferred Stock, including the APS. The Fund might have to liquidate
portfolio securities to finance such redemptions.

     In the absence of approval by a majority of the Fund's Board, including a
majority of the directors who are not "interested persons" of the Fund within
the meaning of the 1940 Act, any amendment to the Fund's Articles of
Incorporation to convert the Fund to an open-end investment company would
require the vote of the holders of 66 2/3% of the outstanding shares of the
Fund's capital stock. See "Description of Common Stock--Certain Anti-Takeover
Provisions of the Articles of Incorporation" in the Prospectus.

                                     RATINGS

     Municipal bonds are rated by Moody's and S&P. Moody's also publishes
separate ratings for municipal notes. Descriptions of these ratings, together
with the ratings assigned by Moody's and S&P to commercial paper, are set forth
below.

DESCRIPTION OF MOODY'S FOUR HIGHEST 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, or fluctuation of protective elements
may be of greater amplitude, or there may be other elements present which make
the long-term risks appear somewhat larger than in Aaa securities.

     A. Bonds which are rated A possess many favorable investment attributes and
are considered to be upper medium grade obligations. Factors giving security to
principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment sometime in the future.

     Baa. Bonds which are rated Baa are considered to be 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.

     NOTE: Those bonds in the Aa, A and Baa groups which Moody's believes
possess the strongest investment attributes are designated by the symbols Aa1,
A1 and Baa1.

DESCRIPTION OF S&P'S FOUR HIGHEST 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.

     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 interest
and repay principal. Whereas it normally exhibits adequate 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.

     NOTE: Plus (+) or Minus (-): The ratings from "AA" to "BBB" may be modified
by the addition of a plus or minus sign to show relative standing within the
major categories.



     DESCRIPTION OF MOODY'S HIGHEST 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 or both.

     MIG-2/VMIG-2. This designation denotes high quality. Margins of protection
are ample although not so large as in the preceding group.

     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 two higher rating categories are as follows:

     SP-1. Very strong or strong capacity to pay principal and interest. Those
issues determined to possess overwhelming safety characteristics will be given a
plus (+) designation.

     SP-2. Satisfactory capacity to pay principal and interest.

DESCRIPTION OF COMMERCIAL PAPER RATINGS

     Issuers assigned Prime-1 by Moody's have a superior capacity for repayment
of short-term promissory obligations. Prime-1 repayment capacity will often be
evidenced by the following characteristics: leading market positions in well-
established industries; high rates of return on funds employed; conservative
capitalization structures with moderate reliance on debt and ample asset
protection; broad margins in earning coverage of fixed financial charges and
high internal cash generation; well established access to a range of financial
markets and assured sources of alternate liquidity. Issuers assigned Prime-2
have a strong capacity for repayment of senior short-term promissory
obligations. This will normally be evidenced by many of the characteristics
cited above but to a lesser degree. Earnings trends and coverage ratios, while
sound, will be more subject to variation. Capitalization characteristics, while
still appropriate, may be more affected by external conditions. Ample alternate
liquidity is maintained.

     Issues assigned A by S&P, the highest rating category, are regarded as
having the greatest capacity for timely repayment. Issues in this category are
delineated with the numbers 1, 2 and 3 to indicate the relative degree of
safety. The A-1 designation indicates that the degree of safety regarding timely
payment is strong. Those issues determined to possess extremely strong safety
characteristics are denoted with a plus sign (+) designation. The A-2
designation indicates that the capacity for timely payment is satisfactory.
However, the relative degree of safety is not as high as for issues designated
A-1.

                                       A-2


                                                                      APPENDIX B

                            RATING AGENCY GUIDELINES

     GENERAL

     The guidelines described below have been developed by Moody's and S&P in
connection with other issuances of asset-backed and similar securities,
including debt obligations and adjustable rate preferred stock, generally on a
case-by-case basis through discussions with the issuers of these securities. The
guidelines are designed to ensure that assets underlying outstanding debt or
preferred stock will be sufficiently varied and will be of sufficient quality
and amount to justify investment grade ratings. The guidelines do not have the
force of law, but they have been adopted by the Fund in order to satisfy current
requirements necessary for Moody's and S&P to issue the above- described ratings
for shares of each series of APS, which ratings are generally relied upon by
institutional investors in purchasing such securities. In the context of a
closed-end investment company such as the Fund, therefore, the guidelines
provide a set of tests for portfolio composition and asset coverage that
supplement (and in some cases are more restrictive than) the applicable
requirements under the 1940 Act. A rating agency's guidelines will apply to
shares of any series of APS only so long as such rating agency is rating such
shares.

     The Fund intends to maintain a Discounted Value for its portfolio at least
equal to the APS Basic Maintenance Amount and, in addition, so long as S&P is
rating the shares of any series of APS, the Fund intends to maintain a Minimum
Liquidity Level. Moody's and S&P have each established separate guidelines for
determining Discounted Value. To the extent any particular portfolio holding
does not satisfy the applicable rating agency's guidelines, all or a portion of
such holding's value will not be included in the calculation of Discounted Value
(as defined by such rating agency). The Moody's and S&P guidelines do not impose
any limitations on the percentage of Fund assets that may be invested in
holdings not eligible for inclusion in the calculation of the Discounted Value
of the Fund's portfolio. The amount of such assets included in the portfolio at
any time may vary depending upon the rating, diversification and other
characteristics of the Eligible Assets included in the portfolio, although it is
not anticipated that in the normal course of business the value of such assets
would exceed 20% of the Fund's total assets.

     In managing the Fund's portfolio, UBS Global AM will not alter the
composition of the Fund's portfolio if, in the reasonable belief of UBS Global
AM, the effect of any such alteration would be to cause the Fund to have
Eligible Assets with an aggregate Discounted Value, as of the immediately
preceding Valuation Date, less than the APS Basic Maintenance Amount of such
Valuation Date; provided, however, that in the event that, as of the immediately
preceding Valuation Date, the aggregate Discounted Value of the Fund's Eligible
Assets exceeded the APS Basic Maintenance Amount by five percent or less, UBS
Global AM will not alter the composition of the Fund's portfolio in a manner
reasonably expected to reduce the aggregate Discounted Value of the Fund's
Eligible Assets unless the Fund shall have confirmed that, after giving effect
to such alteration, the aggregate Discounted Value of the Fund's Eligible Assets
would exceed the APS Basic Maintenance Amount.

     Upon any failure to maintain the required Discounted Value, the Fund will
seek to alter the composition of its portfolio to reattain the APS Basic
Maintenance Amount on or prior to the APS Basic Maintenance Cure Date, thereby
incurring additional transaction costs and possible losses and/or gains on
dispositions of portfolio securities. To the extent any such failure is not
cured in a timely manner, shares of each series of APS will be subject to
redemption if either Moody's or S&P is rating such shares. The APS Basic
Maintenance Amount includes the sum of (i) the aggregate liquidation value of
each series of APS then Outstanding and (ii) certain accrued and projected
payment obligations of the Fund. See "Asset Maintenance."



     The Fund may, but is not required to, adopt any modifications to these
guidelines that may hereafter be established by Moody's and S&P. Failure to
adopt any such modifications, however, may result in a change in the ratings
described above or a withdrawal of ratings altogether. In addition, any rating
agency providing a rating for the shares of any series of APS may, at any time,
change or withdraw any such rating. As set forth in the APS Provisions, the
Board of Directors may, without Stockholder approval, modify certain definitions
or policies which have been adopted by the Fund pursuant to the rating agency
guidelines, provided the Board of Directors has obtained written confirmation
from Moody's and S&P, as appropriate, that any such change would not impair the
ratings then assigned by Moody's and S&P to any series of APS.

     As described by Moody's and S&P, a preferred stock rating is an assessment
of the capacity and willingness of an issuer to pay preferred stock obligations.
The ratings on any series of the APS are not recommendations to purchase, hold
or sell shares of such series of APS, inasmuch as the ratings do not comment as
to market price or suitability for a particular investor nor do the rating
agency guidelines described above address the likelihood that a holder of shares
of any series of APS will be able to sell such shares in an Auction. The ratings
are based on current information furnished to Moody's and S&P by the Fund and
UBS Global AM , and information obtained from other sources. The ratings may be
changed, suspended or withdrawn as a result of changes in, or the unavailability
of, such information. The Fund's Common Stock has not been rated by a nationally
recognized statistical rating organization.

     S&P AAA RATING GUIDELINES. For purposes of calculating the Discounted Value
of the Fund's portfolio under current S&P guidelines, the fair market value of
Municipal Obligations eligible for consideration under such guidelines ("S&P
Eligible Assets") must be discounted by certain discount factors set forth in
the table below ("S&P Discount Factors"). The Discounted Value of a Municipal
Obligation under S&P guidelines is the fair market value thereof divided by the
S&P Discount Factor. The S&P Discount Factor used to discount a particular
Municipal Obligation will be determined by reference to the "S&P Exposure
Period" as determined by S&P (currently, 3 Business Days) and the S&P rating on
such Municipal Obligation. S&P Discount Factors for a range of exposure periods
are set forth below:

     Since the S&P Exposure Period currently applicable to the Fund is 3
Business Days, the S&P Discount Factors currently applicable to S&P Eligible
Assets will be determined by reference to the factors set forth opposite the
line entitled "3 Business Days." Notwithstanding the foregoing:

     (i) the S&P Discount Factor for short-term Municipal Obligations will be
115%, so long as such Municipal Obligations are rated A-1+ or SP-1+ by S&P and
mature or have a demand feature exercisable within 30 days or less, or 125%, if
such Municipal Obligations are not rated by S&P but are rated VMIG-1, MIG-1 or
Prime-1 by Moody's; provided, however, that any such Moody's-rated short-term
Municipal Obligations which have demand features exercisable within 30 days or
less must be backed by a letter of credit, liquidity facility or guarantee from
a bank or other financial institution with a short-term rating of at least A-1+
from S&P; and further provided that such Moody's-rated short-term Municipal

                                       B-2


Obligations may comprise no more than 50% of short-term Municipal Obligations
that qualify as S&P Eligible Assets; and

     (ii) no S&P Discount Factor will be applied to cash or to Receivables for
Municipal Obligations Sold.

     For purposes of the foregoing, Anticipation Notes rated SP-1+ or, if not
rated by S&P, rated MIG-1 or VMIG-1 by Moody's, which do not mature or have a
demand feature at par exercisable in 30 days and which do not have a long-term
rating, will be considered to be short-term Municipal Obligations. "Receivables
for Municipal Obligations Sold," for purposes of calculating S&P Eligible Assets
as of any Valuation Date, means the book value of receivables for Municipal
Obligations sold as of or prior to such Valuation Date if such receivables are
due within five business days of such Valuation Date.

     The S&P guidelines impose certain minimum issue size, issuer, geographical
diversification and other requirements for purposes of determining S&P Eligible
Assets:

     (1)  In order to be considered S&P Eligible Assets, Municipal Obligations
owned by the Fund must:

          (a)  be interest bearing and pay interest at least semi-annually;

          (b)  be payable with respect to principal and interest in US dollars;

          (c)  be publicly rated BBB or higher by S&P or if not rated by S&P but
          rated by Moody's, be rated at least A by Moody's; provided that such
          Moody's-rated Municipal Obligations will be included in S&P Eligible
          Assets only to the extent that the fair market value of such Municipal
          Obligations does not exceed 50% of the aggregate fair market value of
          S&P Eligible Assets. For purposes of determining the S&P Discount
          Factors applicable to such Moody's-rated Municipal Obligations, any
          such municipal obligation will be deemed to have an S&P rating which
          is one full rating category lower than its Moody's rating;

          (d)  not be private placements; and

          (e)  be part of an issue with an original issue size of at least $20
          million or, if of an issue with an original issue size below $20
          million (but in no event lower than $10 million), be issued by an
          issuer with a total of at least $50 million of securities outstanding.

     (2)  Municipal Obligations of any one issuer or guarantor (excluding bond
insurers) will be considered S&P Eligible Assets only to the extent that the
fair market value of such Municipal Obligations does not exceed 10% of the
aggregate fair market value of S&P Eligible Assets, provided that 2% is added to
the applicable S&P Discount Factor for every 1% by which the fair market value
of such Municipal Obligations exceeds 5% of the aggregate fair market value of
S&P Eligible Assets.

     (3)  Municipal Obligations guaranteed or insured by any one bond insurer
will be considered S&P Eligible Assets only to the extent that the fair market
value of such Municipal Obligations does not exceed 25% of the aggregate fair
market value of S&P Eligible Assets.

     (4)  Municipal Obligations issued by issuers in any one state (including
the District of Columbia), territory or possession of the United States will be
considered S&P Eligible Assets only to the extent that the fair market value of
such Municipal Obligations does not exceed 20% of the aggregate fair market
value of S&P Eligible Assets.

                                       B-3


     For so long as shares of the APS are outstanding and S&P is rating such
APS, the Fund will not, unless the Fund has received written confirmation from
S&P that any such action would not impair the rating then assigned by S&P to the
APS, engage in any one or more of the following transactions: engage in reverse
repurchase agreement transactions; borrow money, except that the Fund may,
without obtaining the written confirmation described above, borrow money for the
purposes of clearing securities transactions if the APS Basic Maintenance Amount
would continue to be satisfied after giving effect to such borrowing; issue any
class or series of shares ranking prior to or on a parity with the APS with
respect to the payment of dividends or the distribution of assets upon
dissolution, liquidation or winding up of the Fund, or reissue any APS
previously purchased or redeemed by the Fund; lend portfolio securities; merge
or consolidate with any corporation; engage in repurchase agreement transactions
in which the term of such repurchase obligation is longer than 90 days, in which
the underlying security is a security other than United States Treasury
securities (not inclusive of zero-coupon securities), demand deposits,
certificates of deposit, or bankers acceptances in which the counter-party or
its affiliates have securities rated A-1+ by S&P with respect to such underlying
security; or engage in short sale transactions. In addition, as long as shares
of APS are so rated or unless such confirmation has been received, the Fund will
not enter into interest rate caps, collars or floors, purchase or sell futures
contracts or options thereon or write uncovered put or uncovered call options on
portfolio securities except that (i) the Fund may engage in any S&P Hedging
Transactions based on the Municipal Index, provided that the Fund shall not
engage in any S&P Hedging Transaction based on the Municipal Index (other than
Closing Transactions) which would cause the Fund at the time of such transaction
to own or have sold the least of (1) more than 1,000 outstanding futures
contracts based on the Municipal index, (2) outstanding futures contracts based
on the Municipal Index and on the Treasury Bonds exceeding in number 25% of the
quotient of the fair market value of the Fund's total assets divided by 100,000
or (3) outstanding futures contracts based on the Municipal Index exceeding in
number 10% of the average number of daily traded futures contacts based on the
Municipal Index in the month prior to the time of effecting such transaction as
reported by THE WALL STREET JOURNAL, and (ii) the Fund may engage in S&P Hedging
Transactions based on Treasury Bonds, provided that the Fund shall not engage in
any S&P Hedging Transaction based on Treasury Bonds (other then Closing
Transactions) which would cause the Fund at the time of such transaction to own
or have sold the lesser of (1) outstanding futures contracts based on Treasury
Bonds and on the Municipal Index exceeding in number 25% of the quotient of the
fair market value of the Fiend's total assets divided by 100,000 or (2)
outstanding futures contracts based on Treasury Bonds exceeding in number 10% of
the average number of daily traded futures contacts based on Treasury Bonds in
the month prior to the time of effecting such transaction as reported by THE
WALL STREET JOURNAL.

     For so long as shares of the APS are rated by S&P, the Fund will engage in
Closing Transactions to close out any outstanding futures contract which the
Fund owns or has sold or any outstanding option thereon owned by the Fund in the
event (i) the Fund does not have S&P Eligible Assets with an aggregate
Discounted Value equal to or greater than the APS Basic Maintenance Amount on
two consecutive Valuation Dates and (ii) the Fund is required to pay Variation
Margin on the second such Valuation Date. For so long as shares of the APS are
rated by S&P, the Fund will engage in a Closing Transaction to close out any
outstanding futures contract or option thereon in the month prior to the
delivery month under the terms of such futures contract or option thereon unless
the Fund holds securities deliverable under such terms. For purposes of
determining S&P Eligible Assets to determine compliance with the APS Basic
Maintenance Amount, no amounts on deposit with the Fund's custodian or broker
representing Initial Margin or Variation Margin shall constitute S&P Eligible
Assets. For so long as shares of the APS are rated by S&P, when the Fund writes
a futures contract or option thereon, it will maintain an amount of cash, cash
equivalents or short-term, money market securities in a segregated account with
the Fund's custodian, so that the amount so segregated plus the amount of
Initial Margin and Variation Margin held

                                       B-4


in the account of the Fund's broker equals the fair market value of the futures
contract, except that in the event the Fund writes a futures contract or option
thereon which requires delivery of an underlying security, the Fund shall hold
such underlying security.

     MOODY'S "Aaa" RATING GUIDELINES. For purposes of calculating the Discounted
Value of the Fund's portfolio under current Moody's guidelines, the fair market
value of Municipal Obligations eligible for consideration under such guidelines
("Moody's Eligible Assets") must be discounted by certain discount factors set
forth in the table below ("Moody's Discount Factors"). The Discounted Value of a
municipal obligation under Moody's guidelines is the fair market value thereof
divided by the Moody's Discount Factor. The Moody's Discount Factor used to
discount a particular municipal obligation will be determined by reference to
the "Moody's Exposure Period" currently, the 47-day period commencing on a given
Valuation Date). Moody's Discount Factors for a range of exposure periods are
set forth below:



                                                                MOODY'S DISCOUNT FACTORS

 (1) Moody's rating.
 (2) Municipal Obligations not rated by Moody's but rated BBB-, BBB or BBB+
     by S&P
 (3) Municipal Obligations rated MIG-1, VMIG-1 or Prime-1 or, if not rated by
     Moody's, rated SP-1+ by S&P which do not mature or have a demand feature
     at par exercisable within the Moody's Exposure Period and which do not
     have a long-term rating.
 (4) For the purposes of the definition of Moody's Eligible Assets, these
     securities will have an assumed rating of "A" by Moody's.

     Since the Moody's Exposure Period currently applicable to the Fund is 47
days, the Moody's Discount Factors currently applicable to Moody's Eligible
Assets will be determined by reference to the factors set forth opposite the
line entitled "7 weeks or less."

     Notwithstanding the foregoing, (i) no Moody's Discount Factor will be
applied to short-term Municipal Obligations so long as such Municipal
Obligations are rated at least MIG-1, VMIG-1 or Prime-1 by Moody's and mature or
have a demand feature at par exercisable within the Moody's Exposure Period, and
the Moody's Discount Factor far such Municipal Obligations will be 125% as long
as such Municipal Obligations are rated A-1-/AA or SP-1+/AA by S&P and mature or
have a demand feature at par exercisable within the Moody's Exposure Period and
(ii) no Moody's Discount Factor will be applied to cash or to Receivables for
Municipal Obligations Sold. "Receivables for Municipal Obligations Sold," for
purposes of calculating Moody's Eligible Assets as of any Valuation Date, means
no more than the aggregate of the following: (i) the book value of receivables
for Municipal Obligations sold as of or prior to such Valuation Date if such
receivables are due within five business days of such Valuation Date, and if the
trades which generated such receivables are (x) settled through clearinghouse
firms with respect to which the Fund has received prior written authorization
from Moody's or (y) with counterparties having a Moody's long-term debt rating
of at least Baa3; and (ii) the Moody's Discounted Value of Municipal Obligations
sold as of or prior to such Valuation Date which generated receivables, if such
receivables are due within the Moody's Exposure Period but do not comply with
either of conditions (x) or (y).

                                       B-5


     The Moody's guidelines impose certain minimum issue size, issuer,
geographical diversification and other requirements for purposes of determining
Moody's Eligible Assets, as set forth in the table below:

----------
  *  Municipal Obligations not rated by Moody's but rated at least BBB- by S&P
  ** The referenced percentages represent maximum cumulative totals for the
     related rating category and each lower rating category.

     Current Moody's guidelines also require that Municipal Obligations
constituting Moody's Eligible Assets pay interest in cash, be publicly rated Baa
or higher by Moody's or, if not rated by Moody's but rated by S&P, that they be
rated at least BBB by S&P, and that they not have suspended ratings. For
purposes of determining the Moody's Discount Factors applicable to such
S&P-rated Municipal Obligations, any such Municipal Obligations (excluding
short-term Municipal Obligations) will be deemed to have a Moody's rating which
is one full rating category lower than its S&P rating. For purposes of
calculation of Minimum Issue Size, Maximum Underlying Obligor and Maximum State
or Territory Concentration, Moody's Eligible Assets shall be calculated without
including cash and Municipal Obligations rated MIG-1, VMIG-1 or Prime-1 or, if
not rated by Moody's, rated SP-1+ by S&P, which either mature or have a demand
feature at par exercisable within the Moody's Exposure Period. Where the Fund
sells an asset and agrees to repurchase such asset in the future, the Discounted
Value of such asset will constitute a Moody's Eligible Asset and the amount the
Fund is required to pay upon repurchase of such asset will count as a liability
for the purposes of the APS Basic Maintenance Amount. Where the Fund purchases
an asset and agrees to sell it to a third party in the future, cash receivable
by the Fund thereby will constitute a Moody's Eligible Asset if the long-term
debt of such other party is rated at least A2 by Moody's and such agreement has
a term of 30 days or less; otherwise the Discounted Value of such asset will
constitute a Moody's Eligible Asset.

     Notwithstanding the foregoing, an asset will not be considered a Moody's
Eligible Asset to the extent that it has been irrevocably deposited for the
payment of (A)(i) through (A)(vii) under the definition of APS Basic Maintenance
Amount or it is subject to any material lien, mortgage, pledge, security
interest or security agreement of any kind (collectively, "Liens"), except for
(a) Liens which are being contested in good faith by appropriate proceedings and
which Moody's has indicated to the Fund will not affect the status of such asset
as a Moody's Eligible Asset, (b) Liens for taxes that are not then due and
payable or that can be paid thereafter without penalty, (c) Liens to secure
payment for services rendered or cash advanced to the Fund by UBS Global AM,
State Street Bank and Must Company or the Auction Agent and (d) Liens by virtue
of any repurchase agreement.

     For so long as shares of the APS are outstanding and the APS are rated by
Moody's, the Fund will not, unless it has received written confirmation from
Moody's that any such action would not impair the ratings then assigned by
Moody's to the APS engage in any one or more of the following transactions: (1)
incur any indebtedness, except that the Fund may, without obtaining the prior
written approval described above, incur indebtedness for the purpose of clearing
securities transactions if the Discounted Value of Moody's Eligible Assets would
equal or exceed the APS Basic Maintenance Amount after giving effect to such
indebtedness; (2) issue any class or series of shares ranking prior to or on a
parity with the APS with respect to the payment of dividends or the distribution
of assets upon dissolution,

                                       B-6


liquidation or winding up of the Fund, or reissue any APS previously purchased
or redeemed by the Fund; (3) engage in short sale transactions; or (4) except as
necessary to effect Closing Transactions, engage in transactions in options on
securities, futures contracts or options on futures contracts, except that in
connection with Moody's Hedging Transactions: (A) the Fund may buy call or put
options on securities; (B) the Fund may write covered call options on
securities; (C) the Fund may write put options on securities (D) the Fund may
enter into positions in futures contracts based on the Municipal Index provided
that the Fund shall not engage in any such transaction which would cause the
Fund at the time of such transaction to own or have sold (1) outstanding futures
contracts based on the Municipal Index exceeding in number 10% of the rolling
average number of daily traded futures contracts based on the Municipal Index in
the 30 calendar days prior to the time of effecting such transaction as reported
by THE WALL STREET JOURNAL or (2) outstanding futures contracts based on the
Municipal Index and options on such futures contracts having an aggregate fair
market value (taking into account the fair market value of futures contracts
based on Treasury Bonds) exceeding the fair market value of Moody's Eligible
Assets owned by the Fund; (E) the Fund may enter into futures contracts on
Treasury Bonds provided that the Fund shall not engage in any such transaction
which would cause the Fund at the time of such transaction to own or have sold
(1) outstanding futures contracts based on Treasury Bonds and options on such
futures contracts having an aggregate fair market value (taking into account the
fair market value of futures contracts based on the Municipal Index) exceeding
40% of the aggregate fair market value of Moody's Eligible Assets owned by the
Fund and rated Aa by Moody's (or, if not rated by Moody's but rated by S&P,
rated AAA by S&P), or (2) outstanding futures contracts based on Treasury Bonds
and options on such futures contracts having an aggregate fair market value
(taking into account the fair market value of futures contracts based on the
Municipal Index) exceeding 80% of the aggregate fair market value of Moody's
Eligible Assets owned by the Fund and rated Baa or A by Moody's (or, if not
rated by Moody's but rated by S&P, rated A or AA by S&P); and (F) the Fund may
buy call or put options on futures contracts on the Municipal Index or Treasury
Bonds, may write put options on such futures contracts (provided, that if the
contract would require delivery of a security, that security must be held by the
Fund) and may write call options on such futures if it owns the futures contract
subject to the option. For purposes of the foregoing clauses (D) and (E), the
Fund shall be deemed to own the number of futures contracts that underlie any
outstanding option written by the Fund.

     For so long as shares of the APS are rated by Moody's, the Fund will engage
in Closing Transactions to close out any outstanding futures contract based on
the Municipal Index if the open interest with respect to such futures contracts
based on the Municipal Index as reported by THE WALL STREET JOURNAL is less than
5,000. For so long as shares of APS are rated by Moody's, the Fund will engage
in a Closing Transaction to close out any outstanding futures contract by no
later than the fifth Business Day of the month in which such contract expires
and will engage in a Closing Transaction to close out any outstanding option on
a futures contract by no later than the first Business Day of the month in which
such option expires. For so long as shares of APS are rated by Moody's, the Fund
will engage in transactions with respect to futures contracts or options thereon
having only the next settlement date or the settlement date immediately
thereafter.

     For purposes of valuation of Moody's Eligible Assets (i) if the Fund writes
a call option, the underlying asset will be valued as follows: (A) if the option
is exchange-traded and may be offset readily or if the option expires before the
earliest possible redemption of the APS, at the lower of the Discounted Value of
the underlying security of the option and the exercise price of the option or
(B) otherwise, it has no value; (ii) if the Fund writes a put option, the
underlying asset will be valued as follows: the lesser of (A) exercise price and
(B) the Discounted Value of the underlying security; (iii) if the Fund is a
seller under a futures contract, the underlying security will be valued at the
lower of (A) settlement price and (B) Discounted Value of the underlying
security; provided that, if a contract matures within the Moody's

                                       B-7


Exposure Period, the security may be valued at the settlement price; (iv) if the
Fund is the buyer under a futures contract, the underlying security will be
valued at the lower of (A) the settlement price and (B) the Discounted Value of
the underlying security; provided that, if the contract matures within the
Moody's Exposure Period, the security may be valued at Discounted Value of the
underlying security; and (v) call or put option contracts which the Fund buys
have no value. For so long as shares of the APS are rated by Moody's: (1) the
Fund will not engage in options and futures transactions for leveraging or
speculative purposes; (2) the Fund will not write any anticipatory call options
or sell any anticipatory contracts pursuant to which the Fund hedges the
anticipated purchase of an asset prior to completion of such purchase; (3) the
Fund will not enter into an option or futures transaction unless, after giving
effect thereto, the Fund would continue to have Moody's Eligible Assets with an
aggregate Discounted Value equal to or greater than the APS Basic Maintenance
Amount; (4) for purposes of the APS Basic Maintenance Amount (i) assets in
margin accounts are not Moody's Eligible Assets, (ii) 10% of the settlement
price of assets sold under a futures contract, the settlement price of assets
purchased under a futures contract and the settlement price of an underlying
futures contract if the Fund writes put options on futures contracts will
constitute liabilities of the Fund and (iii) if the Fund writes call options on
futures contracts and does not own the underlying futures contract, 105% of the
fair market value of the underlying futures contract will constitute a liability
of the Fund; (5) the Fund shall enter into only exchange-traded futures and
shall write only exchange-traded options on exchanges approved by Moody's; (6)
where delivery may be made to the Fund with any of a class of securities, the
Fund shall assume for purposes of the APS Basic Maintenance Amount that it takes
delivery of that security which yields it the least value; (7) the Fund will not
engage in forward contracts; (8) the Fund will enter into futures contracts as
seller only if it owns the underlying security; and (9) there shall be a
quarterly audit made of the Fund's futures and options transactions by the
Fund's independent accountants to confirm that the Fund is in compliance with
these standards.

          (ii)      the aggregate number of shares of the APS that are the
     subject of such order;

                                       C-2


          (iii)     to the extent that such Bidder is an Existing Holder:

                    (A)  the number of shares, if any, of the APS subject to any

          and

                    (C)  the number of shares, if any, of the APS subject to any
          Sell Order placed by such Existing Holder; and

          (iv)      to the extent such Bidder is a Potential Holder, the rate
     and number of shares of the APS specified in such Potential Holder's Bid.

     (b)  If any rate specified in any Bid contains more than three figures to
the right of the decimal point, the Auction Agent shall round such rate up to
the next highest one thousandth (.001) of 1%.

     (c)  With respect to an Auction preceding a Rate Period of less than 90
days, if an Order or Orders covering all of the Outstanding shares of the APS
held by any Existing Holder is/are not submitted to the Auction Agent prior to
the Submission Deadline, the Auction Agent shall deem a Hold Order to have been
submitted on behalf of such Existing Holder covering the number of Outstanding
shares of the APS held by such Existing Holder and not subject to Orders
submitted to the Auction Agent. With respect to an Auction preceding a Rate
Period of 90 days or greater, if an Order or Orders covering all of the
Outstanding shares of the APS held by any Existing Holder is/are not submitted
to the Auction Agent prior to the Submission Deadline, the Auction Agent shall
deem a Sell Order to have been submitted on behalf of such Existing Holder
covering the number of Outstanding shares of the APS held by such Existing
Holder and not subject to Orders submitted to the Auction Agent.

     (d)  If any Existing Holder submits through a Broker-Dealer to the Auction
Agent one or more Orders covering in the aggregate more than the number of
Outstanding shares of the APS subject to an Auction held by such Existing
Holder, such Orders shall be considered valid in the following order of
priority:

          (i)       all Hold Orders for shares of the APS shall be considered
     valid, but only up to and including in the aggregate the number of
     Outstanding shares of the APS held by such Existing Holder, and if the
     number of shares of the APS subject to such Hold Orders exceeds the number
     of Outstanding shares of the APS held by such Existing Holder, the number
     of shares subject to each such Hold Order shall be reduced PRO RATA to
     cover the number of Outstanding shares of the APS held by such Existing
     Holder;

          (ii)      (A) any Bid for shares of the APS shall be considered valid
     up to and including the excess of the number of Outstanding shares of the
     APS held by such Existing Holder over the number of shares of the APS
     subject to any Hold Orders referred to in clause (i) above;

                    (B)  subject to subclause (A), if more than one Bid for
          shares of the APS with the same rate is submitted on behalf of such
          Existing Holder and the number of

                                       C-3


          Outstanding shares of the APS subject to such Bids is greater than
          such excess, such Bids shall be considered valid up to and including
          the amount of such excess, and the number of shares of the APS subject
          to each Bid with the same rate shall be reduced PRO RATA to cover the
          number of shares of the APS equal to such excess;

                    (C)  subject to subclauses (A) and (B), if more than one Bid
          for shares of the APS with different rates is submitted on behalf of
          such Existing Holder, such Bids shall be considered valid in the
          ascending order of their respective rates up to and including the
          amount of such excess; and

                    (D)  in any such event, the number, if any, of such
          Outstanding shares of the APS subject to any portion of Bids
          considered not valid in whole or in part under this clause (ii) shall
          be treated as the subject of a Bid for shares of the APS by a
          Potential Holder at the rate therein specified; and

          (iii)     all Sell Orders for shares of the APS shall be considered
     valid up to and including the excess of the number of Outstanding shares of
     the APS held by such Existing Holder over the sum of the APS subject to
     valid Hold Orders referred to in clause (i) above and valid Bids by such
     Existing Holder referred to in clause (ii) above.

     (e)  If more than one Bid for one or more shares of the APS is submitted on
behalf of any Potential Holder, each such Bid submitted shall be a separate Bid
with the rate and number of shares therein specified.

     (f)  Any Order submitted by a Broker-Dealer to the Auction Agent prior to
the Submission Deadline on any Auction Date shall be irrevocable.

     4.   DETERMINATION OF SUFFICIENT CLEARING BIDS, WINNING BID RATE AND
APPLICABLE RATE. (a) Not earlier than the Submission Deadline on each Auction
Date, the Auction Agent shall assemble all valid Orders submitted or deemed
submitted to it by the Broker-Dealers (each such Order as submitted or deemed
submitted by a Broker-Dealer being hereinafter referred to individually as a
"Submitted Hold Order," a "Submitted Bid" or a "Submitted Sell Order," as the
case may be, or as a "Submitted Order" and collectively as "Submitted Hold
Orders," "Submitted Bids" or "Submitted Sell Orders," as the case may be, or as
"Submitted Orders") and shall determine:

          (i)       the excess of the number of Outstanding shares of the APS
     over the number of Outstanding shares of the APS subject to Submitted Hold
     Orders (such excess being hereinafter referred to as the "Available APS");

          (ii)      from the Submitted Orders whether:

                    (A)  the number of Outstanding shares of the APS subject to
          Submitted Bids by Potential Holders specifying one or more rates equal
          to or lower than the Maximum Rate for the APS exceeds or is equal to
          the sum of

                    (B)  the number of Outstanding shares of the APS subject to
          Submitted Bids by Existing Holders specifying one or more rates higher
          than the Maximum Rate and

                                       C-4


                    (C)  the number of Outstanding shares of the APS subject to
          Submitted Sell Orders (in the event such excess or such equality
          exists (other than because the number of shares of the APS in
          subclauses (B) and (C) above is zero because all of the Outstanding
          shares of the APS are subject to Submitted Hold Orders) (such
          Submitted Bids in subclause (A) above being hereinafter referred to
          collectively as "Sufficient Clearing Bids"); and

          (iii)     if Sufficient Clearing Bids, the lowest rate specified in
     such Submitted Bids (the "Winning Bid Rate") which if:

                    (A)(I) each such Submitted Bid from Existing Holders
          specifying such lowest rate and (II) all other such Submitted Bids
          from Existing Holders specifying lower rates were rejected, thus
          entitling such Existing Holders to continue to hold the shares of the
          APS that are subject to such Submitted Bids; and

                    (B)(I) each such Submitted Bid from Potential Holders
          specifying such lowest rate and (II) all other such Submitted Bids
          from Potential Holders specifying lower rates were accepted;

          would result in such Existing Holders described in subclause (A) above
          continuing to hold an aggregate number of Outstanding shares of the
          APS which, when added to the number of Outstanding shares of the APS
          to be purchased by such Potential Holders described in subclause (B)
          above, would equal not less than the Available APS.

     (b)  Promptly after the Auction Agent has made the determinations pursuant
to paragraph (a) of this Section 4, the Auction Agent shall advise the Fund of
the Maximum Rate and, based on such determination, the Applicable Rate for the
next succeeding Rate Period as follows:

          (i)       if Sufficient Clearing Bids exist, that the Applicable Rate
     for the next succeeding Rate Period thereof shall be equal to the Winning
     Bid Rate so determined;

          (ii)      if Sufficient Clearing Bids do not exist (other than because
     all of the Outstanding shares of the APS are subject to Submitted Hold
     Orders), that the Applicable Rate for the next succeeding Rate Period,
     which shall be a Minimum Dividend Period, shall be equal to the Maximum
     Rate; or

          (iii)     if all of the Outstanding shares of the APS are subject to
     Submitted Hold Orders, that the Applicable Rate for the next succeeding
     Rate Period thereof shall be equal to the product of (A)(I) the Reference
     Rate on such Auction Date for such Rate Period, if such Rate Period is less
     than one year or (II) the Treasury Rate on such Auction Date for such Rate
     Period, if such Rate Period is one year or greater, and (B)1 minus the
     maximum marginal regular federal individual income tax rate applicable to
     ordinary income or the maximum marginal regular federal corporate income
     tax rate, whichever is greater; provided, however, that if the Fund has
     notified the Auction Agent of its intent to allocate to the APS in such
     Rate Period any net capital gains or other income taxable for Federal
     income tax purposes, the Applicable Rate in respect of that portion of the
     dividend on the APS for such Rate Period that represents the allocation of
     net capital gains or other income taxable for federal income tax purposes
     will be the rate described in

                                       C-5


     the preceding clause (A)(I) or (II), as applicable, without being
     multiplied by the factor set forth in the preceding clause (B).

     5.   ACCEPTANCE AND REJECTION OF SUBMITTED BIDS AND SUBMITTED SELL ORDERS
AND ALLOCATION OF SHARES. Existing Holders shall continue to hold the APS that
are subject to Submitted Hold Orders, and, based on the determinations made
pursuant to paragraph (a) of Section 4 of this Part II, the Submitted Bids and
Submitted Sell Orders shall be accepted or rejected and the Auction Agent shall
take such other action as set forth below:

     (a)  If Sufficient Clearing Bids have been made, all Submitted Sell Orders
shall be accepted and, subject to the provisions of paragraphs (d) and (e) of
this Section 5, Submitted Bids shall be accepted or rejected as follows in the
following order of priority, and all other Submitted Bids for the APS shall be
rejected:

          (i)       Existing Holders' Submitted Bids specifying any rate that is
     higher than the Winning Bid Rate shall be accepted, thus requiring each
     such Existing Holder to sell the APS subject to such Submitted Bids;

          (ii)      Existing Holders' Submitted Bids specifying any rate that is
     lower than the Winning Bid Rate shall be rejected, thus entitling each such
     Existing Holder to continue to hold the APS subject to such Submitted Bids;

          (iii)     Potential Holders' Submitted Bids specifying any rate that
     is lower than the Winning Bid Rate shall be accepted;

          (iv)      each Existing Holder's Submitted Bid for shares of the APS
     specifying a rate that is equal to the Winning Bid Rate shall be rejected,
     thus entitling such Existing Holder to continue to hold shares of the APS
     subject to such Submitted Bid, unless the number of Outstanding shares of
     the APS subject to all such Submitted Bids shall be greater than the number
     of shares of the APS ("remaining shares") in the excess of the Available
     APS over the number of APS subject to Submitted Bids described in clauses
     (ii) and (iii) of this paragraph (a), in which event such Submitted Bid of
     such Existing Holder shall be rejected in part, and such Existing Holder
     shall be entitled to continue to hold the APS subject to such Submitted
     Bid, but only in an amount equal to the number of shares of the APS
     obtained by multiplying the number of remaining shares by a fraction, the
     numerator of which shall be the number of Outstanding shares of the APS
     held by such Existing Holder subject to such Submitted Bid and the
     denominator of which shall be the aggregate number of Outstanding shares of
     the APS subject to such Submitted Bids made by all such Existing Holders
     that specified a rate equal to the Winning Bid Rate; and

          (v)       each Potential Holder's Submitted Bid for shares of the APS
     specifying a rate that is equal to the Winning Bid Rate shall be accepted
     but only in an amount equal to the number of shares of the APS obtained by
     multiplying the number of shares in the excess of the Available APS over
     the number of APS subject to Submitted Bids described in clauses (ii)
     through (iv) of this paragraph (a) by a fraction, the numerator of which
     shall be the number of Outstanding shares of the APS subject to such
     Submitted Bids and the denominator of which shall be the aggregate number
     of Outstanding shares of the APS subject to such Submitted Bids made by all
     such Potential Holders that specified a rate equal to the Winning Bid Rate;
     and

                                       C-6


     (b)  If Sufficient Clearing Bids have not been made (other than because
all of the Outstanding shares of the APS are subject to Submitted Hold Orders),
subject to the provisions of paragraph (d) of this Section 5, Submitted Orders
for the APS shall be accepted or rejected as follows in the following order of
priority and all other Submitted Bids for the APS shall be rejected:

          (i)       Existing Holders' Submitted Bids for shares of the APS
     specifying any rate that is equal to or lower than the Maximum Rate shall
     be rejected, thus entitling such Existing Holders to continue to hold the
     APS subject to such Submitted Bids;

          (ii)      Potential Holders' Submitted Bids for shares of the APS
     specifying any rate that is equal to or lower than the Maximum Rate for the
     APS shall be accepted; and

          (iii)     Each Existing Holder's Submitted Bid for shares of the APS
     specifying any rate that is higher than the Maximum Rate and the Submitted
     Sell Orders of each Existing Holder shall be accepted, thus entitling each
     Existing Holder that submitted any such Submitted Bid or Submitted Sell
     Order to sell the shares of the APS subject to such Submitted Bid or
     Submitted Sell Order, but in both cases only in an amount equal to the
     number of shares of the APS obtained by multiplying the number of shares of
     the APS subject to Submitted Bids described in clause (ii) of this
     paragraph (b) by a fraction, the numerator of which shall be the number of
     Outstanding shares of the APS held by such Existing Holder subject to such
     Submitted Bid or Submitted Sell Order and the denominator of which shall be
     the aggregate number of Outstanding shares of the APS subject to all such
     Submitted Bids and Submitted Sell Orders.

     (c)  If all of the Outstanding shares of the APS are subject to Submitted
Hold Orders, all Submitted Bids for the APS shall be rejected.

     (d)  If, as a result of the procedures described in clause (iv) or (v) of
paragraph (a) or clause (iii) of paragraph (b) of this Section 5, any Existing
Holder would be entitled or required to sell, or any Potential Holder would be
entitled or required to purchase, a fraction of a share of the APS on any
Auction Date, the Auction Agent shall, in such manner as it shall determine in
its sole discretion, round up or down the number of shares of the APS to be
purchased or sold by any Existing Holder or Potential Holder on such Auction
Date as a result of such procedures so that the number of shares of the APS so
purchased or sold by each Existing Holder or Potential Holder on such Auction
Date shall be a whole number of shares of APS.

     (e)  If as a result of the procedures described in clause (v) of paragraph
(a) of this Section 5, any Potential Holder would be entitled or required to
purchase less than a whole share of the APS on any Auction Date, the Auction
Agent shall, in such manner as it shall determine in its sole discretion,
allocate shares of the APS for purchase among Potential Holders so that only
whole shares of the APS are purchased on such Auction Date as a result of such
procedures by any Potential Holder, even if such allocation results in one or
more Potential Holders not purchasing APS on such Auction Date.

     (f)  Based on the results of each Auction for shares of the APS, the
Auction Agent shall determine the aggregate number of shares of the APS to be
purchased and the aggregate number of shares of the APS to be sold by Potential
Holders and Existing Holders on whose behalf each Broker-Dealer submitted Bids
or Sell Orders and, with respect to each Broker-Dealer, to the extent that such
aggregate number of shares to be purchased and such aggregate number of shares
to be sold differ, determine to which other Broker-Dealer or Broker-Dealers
acting for one or more purchasers of shares of the APS such

                                       C-7


Broker-Dealer shall deliver, or from which other Broker-Dealer or Broker-Dealers
acting for one or more sellers of shares of the APS such Broker-Dealer shall
receive, as the case may be, shares of the APS.

     6.   NOTIFICATION OF ALLOCATIONS. In normal circumstances, whenever the
Fund intends to include any net capital gains or other income taxable for
Federal income tax purposes in any dividend on the APS, the Fund may notify the
Auction Agent of the amount to be so included 15 days prior to the Auction Date
on which the Applicable Rate for such dividend is to be established. Whenever
the Auction Agent receives such notice from the Fund, it will in turn notify
each Broker-Dealer, who, on or prior to such Auction Date, in accordance with
its Broker-Dealer Agreement, will notify its Existing Holders and Potential
Holders believed by it to be interested in submitting an Order in the Auction to
be held on such Auction Date.

     7.   MISCELLANEOUS. (a) To the extent permitted by applicable law, the
Board of Directors may interpret or adjust the provisions of the Articles
Supplementary to resolve any inconsistency or ambiguity or to remedy any formal
defect, and may amend the Articles Supplementary with respect to the APS prior
to the issuance thereof.

     (b)  An Existing Holder may sell, transfer or otherwise dispose of APS only
in whole shares and only pursuant to a Bid or Sell Order in accordance with the
procedures described in this Part II or to or through a Broker-Dealer or to a
Person that has delivered a signed copy of a Master Purchaser's Letter to the
Auction Agent; provided that in the case of all transfers other than pursuant to
Auctions, such Existing Holder, its Broker-Dealer or its Agent Member advises
the Auction Agent of such transfer.

     (c)  All of the shares of APS Outstanding from time to time shall be
represented by one global certificate registered in the name of the Securities
Depository or its nominee.

     (d)  either the Fund nor any affiliate thereof may submit an Order in any
Auction, except that any Broker-Dealer that is an affiliate of the Fund may
submit Orders in an Auction, but only if such Orders are not for its own
account.

                                       C-8


                                                                      APPENDIX D

     Period;

          (ii)      whether Sufficient Clearing Bids existed for the
     determination of the Applicable Rate;

     Sell Orders is different than the aggregate number of shares of the APS to
     be purchased by all Potential Holders on whose behalf such Broker-Dealer
     submitted a Bid, the name or names of one or more other Broker-Dealers (and
     the Agent Member, if any, of each such other Broker-Dealer) and the number
     of shares of the APS to be (x) purchased from one or more Existing Holders
     on whose behalf such other Broker-Dealers submitted Bids or Sell Orders, or
     (y) sold to one or more Potential Holders on whose behalf such other
     Broker-Dealers submitted Bids; and

          (v)       the scheduled Auction Date of the next succeeding Auction

(b)  On each Auction Date, each Broker-Dealer that submitted an Order on behalf
of any Existing Holder or Potential Holder shall:

          (i)       advise each Existing Holder and Potential Holder on whose
     behalf such Broker-Dealer submitted a Bid or Sell Order whether such Bid or
     Sell Order was accepted or rejected, in whole or in part;

          (ii)      instruct each Potential Holder on whose behalf such
     Broker-Dealer submitted a Bid that was accepted, in whole or in part, to
     instruct such Bidder's Agent Member to pay to such Broker-Dealer (or its
     Agent Member) through the Securities Depository the amount necessary to
     purchase the number of shares of the APS to be purchased pursuant to such
     Bid against receipt of such shares;

          (iii)     instruct each Existing Holder on whose behalf such
     Broker-Dealer submitted a Bid that was accepted, in whole or in part, or a
     Sell Order that was accepted, in whole or in part, to instruct such
     Bidder's Agent Member to deliver to such Broker-Dealer (or its Agent
     Member) through the Securities Depository the number of shares of the APS
     to be sold pursuant to such Bid or Sell Order against payment therefor;



          (iv)      advise each Existing Holder on whose behalf such
     Broker-Dealer submitted an Order and each Potential Holder on whose behalf
     such Broker-Dealer submitted a Bid of the Applicable Rate for the next
     succeeding Rate Period;

          (v)       advise each Existing Holder on whose behalf such
     Broker-Dealer submitted an Order of the Auction Date of the next succeeding
     Auction; and

          (vi)      advise each Potential Holder on whose behalf such
     Broker-Dealer submitted a Bid that was accepted, in whole or in part, of
     the Auction Date of the next succeeding Auction.

(c)  On the basis of the information provided to it pursuant to paragraph (a)
above, each Broker-Dealer that submitted a Bid or Sell Order shall allocate any
funds received by it in respect of such series pursuant to paragraph (b)(ii)
above, and any shares of the APS received by it pursuant to paragraph (b)(iii)
above, among the Potential Holders, if any, on whose behalf such Broker-Dealer
submitted Bids, the Existing Holders, if any, on whose behalf such Broker-Dealer
submitted Bids or Sell Orders, and any Broker-Dealers identified to it by the
Auction Agent pursuant to paragraph (a)(v) above.

(d)  On the Business Day after the Auction Date, the Securities Depository shall
execute the transactions described above, debiting and crediting the accounts of

                                       D-2


                                                                      APPENDIX E

                      HEDGING AND RELATED INCOME STRATEGIES

     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 the Fund's portfolio. Thus, in a short hedge the Fund takes
a position in a Hedging Instrument the price of which is expected to move in the
opposite direction of the price of the investment being hedged. For example, the
Fund might purchase a put option on a security to hedge against a potential
decline in the value of that security. If the price of the security declined
below the exercise price of the put, the Fund could exercise the put and thus
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 the Fund intends to acquire. Thus, in a
long hedge the Fund takes a position in a Hedging Instrument the price of which
is expected to move in the same direction as the price of the prospective
investment being hedged. For example, the Fund might purchase a call option on a
security it intends to purchase in order to hedge against an increase in the
cost of the security. If the price of the security increased above the exercise
price of the call, the Fund could exercise the call and thus limit its
acquisition cost to the exercise price plus the premium paid and transaction
costs. Alternatively, the Fund might be able to offset the price increase by
closing out an appreciated call option and realizing a gain.

     Hedging Instruments on securities generally are used to hedge against price
movements in one or more particular securities positions that the Fund owns or
intends to acquire. 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
SEC, the several options and futures exchanges upon which they are traded and
the Commodity Futures Trading Commission ("CFTC"), and may become subject to
regulation by various state regulatory authorities. In addition, the Fund's
ability to use Hedging Instruments will be limited by tax considerations. See
"Taxation."

     In addition to the products, strategies and risks described below, UBS
Global AM expects additional opportunities to develop in connection with
options, futures contracts and other hedging techniques. These new opportunities
may become available as UBS Global AM develops new techniques, as regulatory
authorities broaden the range of permitted transactions, and as new options,
futures contracts or other techniques are developed. UBS Global AM may utilize
these opportunities to the extent that they are consistent with the Fund's
investment objective and permitted by the Fund's investment limitations and
applicable regulatory authorities.

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 UBS Global
AM's 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 UBS Global AM 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 indexes 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 the Fund entered into a
short hedge because UBS Global AM 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, the 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 the 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 the Fund's ability
to sell a portfolio security or make an investment at a time when it would
otherwise be favorable to do so, or require that the Fund sell a portfolio
security at a disadvantageous time. The Fund's ability to close out a position
in a 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 counterparty to enter into a transaction closing out the
position. Therefore, there is no assurance that any hedging position can be
closed out at a time and price that is favorable to the Fund.

COVER FOR HEDGING STRATEGIES

     Transactions using Hedging Instruments, other than purchased options,
expose the Fund to an obligation to another party. The Fund will not enter into
any such transactions unless it owns either (1) an offsetting ("covered")
position in securities or other options or futures contracts or (2) cash and
short-term debt securities, with a value sufficient at all times to cover its
potential obligations to the extent not covered as provided in (1) above. The
Fund will comply with SEC guidelines regarding cover for hedging transactions
and will, if the guidelines so require, set aside cash, US 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
the 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 Fund may purchase put and call options, and write (sell) covered call
options and covered put 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 the 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 on the option, minus the premium
received, the Fund would expect to suffer a loss. Writing covered call options
serves as a limited

                                       E-2


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. Options that expire unexercised have no value.

     The Fund may effectively terminate its right or obligation under an option
by entering into a closing transaction. For example, the Fund may terminate its
obligation under a call option that it had written by purchasing an identical
call option; this is known as a closing purchase transaction. Conversely, the
Fund may terminate a position in a put or call option it had purchased by
writing an identical put or call option; this is known as a closing sale
transaction. Closing transactions permit the Fund to realize profits or limit
losses on an option position prior to its exercise or expiration.

     The Fund may purchase or write both exchange-traded and OTC options.
However, exchange-traded or liquid OTC options on Municipal Obligations are not
currently available. 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
counterparty (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 party from whom it purchased the option or to whom it has
written the option (the "counterparty") to make or take delivery of the
underlying investment upon exercise of the option. Failure by the counterparty
to do so would result in the loss of any premium paid by the Fund as well as the
loss of any expected benefit of the transaction.

     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.

     The Fund's ability to establish and close out positions in exchange-listed
options depends on the existence of a liquid market. The Fund intends to
purchase or write only those exchange-traded options for which there appears to
be a liquid secondary market. However, there can be no assurance that such a
market will exist at any particular time. Closing transactions can be made for
OTC options only by negotiating directly with the counterparty, or by a
transaction in the secondary market if any such market exists. Although the Fund
will enter into 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
counterparty, the Fund might be unable to close out an OTC option position at
any time prior to its expiration.

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

     In the event that options on indexes of municipal and non-municipal debt
securities become available, the Fund may purchase and write put and call
options on such indexes in much the same manner as the more traditional options
discussed above, except that index options may serve as a hedge against overall

                                       E-3


fluctuations in the debt securities market (or market sectors) rather than
anticipated increases or decreases in the value of a particular security.

FUTURES

     The Fund may purchase and sell municipal bond index futures, other interest
rate futures and options thereon. 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, using a strategy similar
to that used for writing covered call options on securities or indexes.
Similarly, writing covered put options on futures contracts can serve as a
limited long hedge.

     Futures strategies also can be used to manage the average duration of the
Fund's portfolio. If UBS Global AM wishes to shorten the average duration of the
Fund, the Fund may sell a futures contract or a call option thereon, or purchase
a put option on that futures contract. If UBS Global AM wishes to lengthen the
average duration of the 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 the 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, US 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 with respect to an open
futures position. When the Fund purchases an option on a future, the premium
paid plus transaction costs is all that is at risk. In contrast, when the Fund
purchases or sells a futures contract or writes a call option thereon, it is
subject to daily variation margin calls that could be substantial in the event
of adverse price movements. If the Fund has insufficient cash to meet daily
variation margin requirements, it might need to sell securities at a time when
such sales are disadvantageous.

     Holders and writers of futures positions and options on futures can enter
into offsetting closing transactions, similar to closing transactions on
options, by selling or purchasing, respectively, an instrument identical to the
instrument held or written. Positions in futures and options on futures may be
closed only on an exchange or board of trade that provides a secondary market.
The Fund intends to enter into futures transactions only on exchanges or boards
of trade where there appears to be a liquid secondary market. However, there can
be no assurance that such a market will exist for a particular contract at a
particular time. Secondary markets for options on futures are currently in the
development stage, and the Fund will not trade options on futures on any
exchange or board of trade unless, in UBS Global AM's opinion, the markets for
such options have developed sufficiently that the liquidity risks for such
options are not greater than the corresponding risks for futures.

     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

                                       E-4


losses because prices could move to the daily limit for several consecutive days
with little or no trading, thereby preventing liquidation of unfavorable
positions.

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

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

GUIDELINE FOR FUTURES AND RELATED OPTIONS

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

     The Fund may use the following hedging instruments:

     OPTIONS ON DEBT SECURITIES - A call option is a 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,
or upon the expiration, of the option. The writer of the call option, who
receives the premium, has the obligation, upon exercise of the option, 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 or upon expiration. The writer of the put option, who receives the premium,
has the obligation, upon exercise, 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 US 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

                                       E-5


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, municipal debt futures contracts do not exist.

     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 put.

     INTEREST RATE PROTECTION TRANSACTIONS - The Fund may enter into interest
rate protection transactions, including interest rate swaps and interest rate
caps, collars and floors. Interest rate swap transactions involve an agreement
between two parties to exchange payments that are based, for example, on
variable and fixed rates of interest and that are calculated on the basis of a
specified amount of principal (the "notional principal amount") for a specified
period of time. Interest rate cap and floor transactions involve an agreement
between two parties in which the first party agrees to make payments to the
counterparty when a designated market interest rate goes above (in the case of a
cap) or below (in the case of a floor) a designated level on predetermined dates
or during a specified time period. Interest rate collar transactions involve an
agreement between two parties in which payments are made when a designated
market interest rate either goes above a designated level or goes below a
designated floor level on predetermined dates or during a specified time period.

     The Fund would enter into interest rate protection transactions to preserve
a return or spread on a particular investment or portion of its portfolio, to
protect against any increase in the price of securities the Fund anticipates
purchasing at a later date or to effectively fix the rate of interest that it
pays on one or more borrowings or series of borrowings. The Fund would use these
transactions as a hedge and not as a speculative investment. Interest rate
protection transactions are subject to risks comparable to those described above
with respect to other hedging strategies.

     The Fund may enter into interest rate swaps, caps, collars and floors on
either an asset-based or liability-based basis, depending on whether it is
hedging its assets or its liabilities, and will usually enter into interest rate
swaps on a net basis (I.E., the two payment streams are netted out, with the
Fund receiving or paying, as the case may be, only the net amount of the two
payments). Inasmuch as these interest rate protection transactions are entered
into for good faith hedging purposes, and inasmuch as segregated accounts will
be established with respect to such transactions, UBS Global AM and the Fund
believe such obligations do not constitute senior securities and, accordingly,
will not treat them as being subject to its borrowing restrictions. The net
amount of the excess, if any, of the Fund's obligations over its entitlements
with respect to each interest rate swap will be accrued on a daily basis and an
amount of cash, US government securities or other liquid high grade debt
obligations having an aggregate net asset value at least equal to the accrued
excess will be maintained in a segregated account by a custodian that satisfies
the requirements of the 1940 Act. The Fund also will establish and maintain such
segregated accounts with respect to its total obligations under any interest
rate swaps that are not entered into on a net basis and with respect to any
interest rate caps, collars and floors that are written by the Fund.

     The Fund will enter into interest rate protection transactions only with
banks and recognized securities dealers determined by UBS Global AM to present
minimal credit risks in accordance with

                                       E-6


guidelines established by the Fund's board of directors. If there is a default
by the other party to such a transaction, the Fund will have to rely on its
contractual remedies (which may be limited by bankruptcy, insolvency or similar
laws) pursuant to the agreements related to the transaction.

     The swap market has grown substantially in recent years with a large number
of banks and investment banking firms acting both as principals and as agents
utilizing standardized swap documentation. Caps, collars and floors are more
recent innovations for which documentation is less standardized, and
accordingly, they are less liquid than swaps.
