DEAR SHAREHOLDER,

We present you with the annual report for UBS RMA Money Market Portfolio; UBS

Municipal Money Fund; UBS RMA New York Municipal Money Fund; and UBS RMA New
Jersey Municipal Money Fund, for the fiscal year ended June 30, 2005.

PERFORMANCE

With short-term interest rates rising during the fiscal year, the yields
available on money market securities rose as well. As of June 30, 2005, the
funds' seven day current yields were: UBS RMA Money Market Portfolio: 2.63%; UBS
RMA U.S. Government Portfolio: 2.46%; UBS RMA Tax-Free Fund Inc.: 1.88%; UBS RMA
California Municipal Money Fund: 1.71%; UBS RMA New York Municipal Money Fund:

AN INTERVIEW WITH THE PORTFOLIO MANAGERS

Q. HOW WOULD YOU DESCRIBE THE ECONOMIC ENVIRONMENT DURING THE REPORTING PERIOD?

A. The US economy faced a number of challenges during the reporting period,
   including record high energy prices, rising interest rates, a mixed job
   market, uncertainty surrounding the US presidential election and challenging
   geopolitical events. Despite these issues, the economy proved to be
   surprisingly resilient. Following a 3.3% gain in the second quarter of 2004,
   gross domestic product (GDP) was a robust 4.0% in the third quarter, and 3.8%
   in both the fourth quarter of 2004 and the first quarter of 2005. Advance
   estimates for second quarter GDP growth were 3.4%, a slight decline.

Q. HOW DID THE FEDERAL RESERVE BOARD (THE "FED") REACT IN THIS ECONOMIC
   ENVIRONMENT?

A. Given the strength of the economy, it became increasingly clear that the
   Fed's accommodative monetary policy would change and it would begin to raise
   interest rates in an attempt to ward off a potential increase in inflation.
   As expected, the Fed raised the federal funds rate (or "fed funds" rate)--the
   rate that banks charge one another for funds they borrow on an overnight
   basis--from 1.00% to 1.25% at the end of June, 2004. This was the first rate
   hike in four years.

   The Fed again raised rates in 0.25% increments on eight more occasions over
   the fiscal year, bringing the fed funds rate to 3.25%. Coinciding with its
   last rate hike in June 2005, the Fed said; "Although energy prices have risen
   further, the expansion remains firm and labor market conditions continue to
   improve gradually. Pressures on inflation have stayed elevated, but
   longer-term inflation expectations remain well contained." The Fed also said
   it expected to raise rates at a "measured" pace, which it did by raising
   rates another 0.25% to 3.50% on August 9, after the period closed.

Q. HOW WERE THE PORTFOLIOS POSITIONED DURING THE FISCAL YEAR?

A. For the first half of the fiscal year, we employed a "barbell" strategy by
   purchasing securities at both ends of the maturity spectrum. Our longer-term
   securities, with maturities up to one year, were used to lock in higher
   rates, while our shorter-term securities, with maturities of one month or
   less, provided liquidity and gave us the ability to reinvest at higher yields
   as the Fed increased interest rates.

   However, as the period progressed, we let the weighted average maturity of
   most portfolios drift shorter, with the exception of UBS RMA California
   Municipal Money Fund. This was done in order to take advantage of the rising
   rate environment. In particular, we targeted securities maturing around the
   dates of the Fed meetings in order to maximize our ability to capture higher
   yields. We also moved from our barbell structure to a more "bulleted" yield
   curve position, in which we emphasized securities with three- to six-month
   maturities. Generally, a bullet strategy may perform better in a rising rate
   environment.

Q. WHAT TYPES OF SECURITIES DID YOU EMPHASIZE FOR THE PORTFOLIOS?

A. For both UBS RMA Money Market Portfolio and UBS RMA U.S. Government
   Portfolio, quality and liquidity remained paramount in our selection process.
   Within UBS RMA U.S. Government Portfolio, we continued to allocate a large
   portion of the portfolio's holdings in US Treasury securities. Within UBS RMA
   Money Market Portfolio, we emphasized commercial paper, which, in the
   environment that characterized much of the period, offered a yield advantage.

                                        2

   This positioning helped maintain the portfolio's overall level of
   diversification and allowed us to meet our liquidity requirements. We also
   diversified the portfolio in other sectors, such as US government agency
   obligations, certificates of deposit and other short-term corporate
   obligations.

   Credit quality and liquidity were also key factors in the portfolio
   positioning for UBS RMA Tax-Free Fund Inc., UBS RMA California Municipal
   Money Fund, UBS RMA New York Municipal Money Fund and UBS RMA New Jersey
   Municipal Money Fund.

EXPENSE EXAMPLE (UNAUDITED)

As a shareholder of the Funds, you incur ongoing costs, including management
fees; service fees (12b-1 or non-12b-1 fees); and other Fund expenses. These
examples are intended to help you understand your ongoing costs (in dollars) of
investing in each Fund and to compare these costs with the ongoing costs of
investing in other mutual funds.

The examples below are based on an investment of $1,000 invested at the
beginning of the period and held for the entire period, January 1, 2005 to June
30, 2005.

ACTUAL EXPENSES

The first line in the table below for each Fund provides information about its
actual account values and actual expenses. You may use the information in this
line, together with the amount you invested, to estimate the expenses that you
paid over a period. Simply divide your account value by $1,000 (for example, an
$8,600 account value divided by $1,000 = 8.6), then multiply the result by the
number in the first line for each respective Fund under the heading entitled
"Expenses Paid During Period" to estimate the expenses you paid on your account
during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line in the table below for each Fund provides information about
hypothetical account values and hypothetical expenses based on that Fund's
actual expense ratio and an assumed rate of return of 5% per year before
expenses, which is not the Fund's actual return. The hypothetical account values
and expenses may not be used to estimate the actual ending account balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in a Fund and other funds. To do so, compare these 5%
hypothetical examples with the 5% hypothetical examples that appear in the
shareholder reports of other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs. Therefore, the second line in the table for each Fund is useful
in comparing ongoing costs only and will not help you determine the relative
total costs of owning different funds if those funds impose transactional
costs--for example, sales charges (loads), redemption fees, or exchange fees. In
addition, if those transactional costs were included, your costs for those other
funds would have been higher.

The example does not reflect Resource Management Account(R) (RMA(R)) Program or
Business Services Account BSA(R) Program fees as these are external to the Funds
and relate to those programs.

Notes to Financial Statements


ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

UBS RMA Money Fund Inc. (the "Corporation") and UBS RMA Tax-Free Fund Inc. ("RMA
Tax-Free") were organized under the laws of Maryland on July 2, 1982 and are
registered with the Securities and Exchange Commission under the Investment
Company Act of 1940, as amended, as open-end management investment companies.
RMA Tax-Free is a diversified mutual fund and the Corporation is a series mutual
fund with three portfolios, each of which are diversified series: UBS RMA Money
Market Portfolio ("Money Market Portfolio"), UBS RMA U.S. Government Portfolio
("U.S. Government Portfolio") and UBS Retirement Money Fund. The financial
statements of UBS Retirement Money Fund are not included herein.

UBS Managed Municipal Trust ("Managed Municipal Trust") and UBS Municipal Money
Market Series ("Municipal Money Market Series") were organized under
Massachusetts law by Declarations of Trust dated November 21, 1986 and September
14, 1990, respectively, and are registered with the Securities and Exchange
Commission under the Investment Company Act of 1940, as amended, as open-end
management investment companies. Managed Municipal Trust currently offers two
non-diversified series: UBS RMA California Municipal Money Fund ("RMA
California") and UBS RMA New York Municipal Money Fund ("RMA New York").
Municipal Money Market Series currently offers one non-diversified series: UBS
RMA New Jersey Municipal Money Fund ("RMA New Jersey", and when referred
together with Money Market Portfolio, U.S. Government Portfolio, RMA Tax-Free,
RMA California and RMA New York, collectively, the "Funds").

In the normal course of business the Funds may enter into contracts that contain
a variety of representations or that provide indemnification for certain
liabilities. The Funds' maximum exposure under these arrangements is unknown, as
this would involve future claims that may be made against the Funds that have
not yet occurred. However, the Funds have not had prior claims or losses
pursuant to these contracts and expect the risk of loss to be remote.

The preparation of financial statements in accordance with U.S. generally
accepted accounting principles requires the Funds' management to make estimates
and assumptions that affect the reported amounts and disclosures in the
financial statements. Actual results could differ from those estimates. The
following is a summary of significant accounting policies:

VALUATION AND ACCOUNTING FOR INVESTMENTS AND INVESTMENT INCOME--Investments are
valued at amortized cost, unless a Fund's Board of Directors/Trustees (the
"Board") determines that this does not represent fair value. Periodic review and
monitoring of the valuation of securities held by the Funds is performed in an
effort to ensure that amortized cost approximates market value. Investment
transactions are recorded on the trade date. Realized gains and losses from
investment transactions are calculated using the identified cost method.
Interest income is recorded on an accrual basis. Premiums are amortized and
discounts are accreted as adjustments to interest income and the identified cost
of investments.

                                       57

REPURCHASE AGREEMENTS--The Money Market Portfolio and the U.S. Government
Portfolio may purchase securities or other obligations from a bank or securities
dealer (or its affiliate), subject to the seller's agreement to repurchase them
at an agreed upon date (or upon demand) and price. The Money Market Portfolio
and the U.S. Government Portfolio maintain custody of the underlying obligations
prior to their repurchase, either through their regular custodian or through a
special "tri-party" custodian or sub-custodian that maintains a separate account
for both the Money Market Portfolio and/or the U.S. Government Portfolio and
their counterparty. The underlying collateral is valued daily on a
mark-to-market basis to ensure that the value, including accrued interest, is at
least equal to the repurchase price. In the event of default of the obligation
to repurchase, the Money Market Portfolio and the U.S. Government Portfolio
generally have the right to liquidate the collateral and apply the proceeds in
satisfaction of the obligation. Repurchase agreements involving obligations
other than U.S. 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 counterparty insolvency. If the seller
(or seller's guarantor, if any) becomes insolvent, the Money Market Portfolio
and the U.S. Government Portfolio may suffer delays, costs and possible losses
in connection with the disposition or retention of the collateral. Under certain
circumstances, in the event of default or bankruptcy by the other party to the
agreement, realization and/or retention of the collateral may be subject to
legal proceedings. The Money Market Portfolio and the U.S. Government Portfolio
may participate in joint repurchase agreement transactions with other funds
managed, advised or sub-advised by UBS Global Asset Management (US) Inc. ("UBS
Global AM"). UBS Global AM is an indirect wholly owned asset management
subsidiary of UBS AG, an internationally diversified organization with
headquarters in Zurich, Switzerland and operations in many areas of the
financial services industry.

DIVIDENDS AND DISTRIBUTIONS--Dividends and distributions to shareholders are
recorded on the ex-dividend date. The amount of dividends and distributions is
determined in accordance with federal income tax regulations, which may differ
from U.S. generally accepted accounting principles. These "book/tax" differences
are either considered temporary or permanent in nature. To the extent these
differences are permanent in nature, such amounts are reclassified within the
capital accounts based on their federal tax-basis treatment; temporary
differences do not require reclassification.

CONCENTRATION OF RISK

The ability of the issuers of the debt securities held by the Funds to meet
their obligations may be affected by economic developments, including those
particular to a specific industry, country or region.

Additionally, RMA California, RMA New York and RMA New Jersey follow an
investment policy of investing primarily in municipal obligations of one state.

                                       58
<Page>

Economic changes affecting each state and certain of its public bodies and
municipalities may affect the ability of issuers within each state to pay
interest on, or repay principal of, municipal obligations held by each of those
Funds.

INVESTMENT ADVISOR AND ADMINISTRATOR

Each Fund's Board has approved an investment advisory and administration
contract ("Advisory Contract") for each Fund with UBS Financial Services Inc.,
an indirect wholly owned subsidiary of UBS AG, under which UBS Financial
Services Inc. serves as investment advisor and administrator of the Funds. In
accordance with the Advisory Contract, each Fund pays UBS Financial Services
Inc. an investment advisory and administration fee, which is accrued daily and
paid monthly, in accordance with the following schedule:

</Table>

For the period August 1, 2004 through June 30, 2005, UBS Financial Services Inc.
voluntarily waived $43,414 of its investment advisory and administration fees
for the Money Market Portfolio.

UBS Global AM serves as sub-advisor and sub-administrator to the Funds pursuant
to sub-advisory and sub-administration contracts between UBS Financial Services
Inc. and UBS Global AM (each a "Sub-Advisory Contract"). In accordance with each
Sub-Advisory Contract, UBS Financial Services Inc. (not the

                                       59
<Page>

Funds) pays UBS Global AM a fee, accrued daily and paid monthly, at an annual
rate of 0.08% of the respective Fund's average daily net assets.

ADDITIONAL INFORMATION REGARDING COMPENSATION TO AFFILIATE OF A BOARD MEMBER

Effective March 1, 2005, Professor Meyer Feldberg accepted the position of
senior advisor to Morgan Stanley, resulting in him becoming an interested board
member of the Funds. The Funds have been informed that Professor Feldberg's role
at Morgan Stanley does not involve matters directly affecting any UBS funds. UBS
Global AM executes Fund portfolio transactions through Morgan Stanley based on
the firm's ability to provide best execution of the transactions. During the
year ended June 30, 2005, the Funds purchased and sold certain securities (e.g.,
fixed income securities) in principal trades with Morgan Stanley having
aggregate values as follows:

<Table>

RMA California                                                       762,994,838
RMA New York                                                         277,543,000
RMA New Jersey                                                       118,010,000
</Table>

Morgan Stanley received compensation in connection with these trades, which may
have been in the form of a "mark-up" or "mark-down" of the price of the
securities, a fee from the issuer for maintaining a commercial paper program, or
some other form of compensation. Although the precise amount of this
compensation is not generally known by UBS Global AM, UBS Global AM believes
that under normal circumstances it represents a small portion of the total value
of the transactions.

DISTRIBUTION PLAN

UBS Global AM is the principal underwriter of each Fund's shares and has
appointed UBS Financial Services Inc. as a dealer for the sale of the Funds'
shares. Under the plans of distribution, U.S. Government Portfolio, RMA
Tax-Free, RMA California and RMA New York pay UBS Global AM a monthly service
fee at the annual rate of up to 0.15% of average daily net assets and RMA
New Jersey is authorized to pay at the annual rate of up to 0.12% of average
daily net assets, for providing certain shareholder services. Currently, UBS
Global AM is compensated for providing such services at the annual rate of
0.125% for each of those Funds except for RMA New Jersey, which pays at the
annual rate of 0.12%. No such fees were charged by UBS Global AM for the similar
services provided to the Money Market Portfolio during the fiscal year ended
June 30, 2005; however, subsequent to the fiscal year end, a shareholder service
plan became

                                       60

SECURITIES LENDING

Each Fund may lend securities up to 33 1/3% of its total assets to qualified
broker-dealers or institutional investors. The loans are secured at all times by
cash, U.S. government securities or irrevocable letters of credit in an amount
at least equal to the market value of the securities loaned, plus accrued
interest and dividends, determined on a daily basis and adjusted accordingly.
Each Fund will regain ownership of loaned securities to exercise certain
beneficial rights; however, each Fund may bear the risk of delay in recovery of,
or even loss of rights in, the securities loaned should the borrower fail
financially. Each Fund receives compensation for lending its securities from
interest or dividends earned on the cash, U.S. government securities or
irrevocable letters of credit held as collateral, net of fee rebates paid to the
borrower plus reasonable administrative and custody fees. UBS Financial Services
Inc. and other affiliated broker-dealers have been approved as borrowers under
the Funds' securities lending program. UBS Securities LLC is the lending agent
for each Fund. For the year ended June 30, 2005, UBS Securities LLC earned $654
and $82,693 in compensation from the Money Market Portfolio and the U.S.
Government Portfolio, respectively, as the Funds' lending agent. At June 30,
2005, the U.S. Government Portfolio owed UBS Securities LLC $8,245 in
compensation as the Fund's lending agent. At June 30, 2005, the U.S. Government
Portfolio had securities on loan having a

                                       61

market value of $395,436,298. The U.S. Government Portfolio's custodian held
cash equivalents as collateral for securities loaned of $40,606,976. In
addition, the U.S. Government Portfolio's custodian held U.S. Government agency
securities having an aggregate value of $363,271,940 as collateral for portfolio
securities loaned as follows:

RMA Tax-Free, RMA California, RMA New York and RMA New Jersey did not have any
securities lending activity during the year ended June 30, 2005. The Money
Market Portfolio did not have any securities on loan at June 30, 2005 and did
not owe UBS Securities LLC any compensation as the Fund's lending agent.

BANK LINE OF CREDIT

RMA Tax-Free participates with certain other funds managed, advised or
sub-advised by UBS Global AM in a $100 million committed credit facility with
State Street Bank and Trust Company ("Committed Credit Facility"), to be
utilized for temporary financing until the settlement of sales or purchases of
portfolio securities, the repurchase or redemption of shares of RMA Tax-Free at
the request of

                                       62
<Page>

shareholders and other temporary or emergency purposes. Under the Committed
Credit Facility arrangement, RMA Tax-Free has agreed to pay commitment fees, pro
rata, based on the relative asset size of the funds in the Committed Credit
Facility. Interest will be charged to RMA Tax-Free at the overnight federal
funds rate in effect at the time of borrowings, plus 0.50%. For the year ended
June 30, 2005, RMA Tax-Free had an average daily amount of borrowing outstanding
under the Committed Credit Facility of $41,789,862 for 6 days with a related
weighted average annualized interest rate of 2.81%, which resulted in $19,572 of
interest expense.

FEDERAL TAX STATUS

Each Fund intends to distribute all or substantially all of its income and to
comply with the other requirements of the Internal Revenue Code applicable to
regulated investment companies. Accordingly, no provision for federal income
taxes is

                                       63
<Page>

required. In addition, by distributing during each calendar year substantially
all of their net investment income, net realized capital gains and certain other
amounts, if any, the Funds intend not to be subject to a federal excise tax.

The tax character of all distributions paid to shareholders by the Money Market
Portfolio and U.S. Government Portfolio during the fiscal years ended June 30,
2005 and June 30, 2004 was ordinary income. The tax character of all
distributions paid to shareholders by RMA Tax-Free, RMA California, RMA New York
and RMA New Jersey during the fiscal years ended June 30, 2005 and June 30, 2004
was tax-exempt income.

At June 30, 2005, the components of accumulated earnings on a tax basis for each
of the Funds were as follows:

SUBSEQUENT EVENT

In June 2005, the shareholders of UBS RMA Money Market Portfolio (the
"Portfolio") approved the adoption of a Shareholder Services Plan (the "Plan").
Under the Plan, the Portfolio will pay a separate fee for shareholder services.
Fees under the Plan will be paid to UBS Global Asset Management (US) Inc. ("UBS
Global AM") as principal underwriter of the Portfolio. UBS Global AM then, in
turn, pays those fees to UBS Financial Services Inc. in its capacity as a dealer
selling the Portfolio's shares to its clients.

In order to offset the additional fees UBS Financial Services Inc. will receive
under the Plan, UBS Financial Services Inc., also the Portfolio's investment
advisor and administrator, has agreed to waive its investment advisory and
administration fee in an amount designed to offset the service fee payable under
the Plan. Effective July 1, 2005, the Portfolio pays a 0.125% service fee to UBS
Global AM, which in turn is paying this service fee to UBS Financial Services
Inc. The Plan permits a service fee at an annual rate of up to 0.15% of the
Portfolio's average daily net assets. However, as allowable, a lower service fee
has been agreed upon by the Portfolio's Board and UBS Global AM. UBS Financial
Services Inc. has agreed to waive a portion of its management fee for as long as
the Plan remains in effect. Upon implementation of the Plan on July 1, 2005, the
investment advisory and administration fee payable to UBS Financial Services
Inc. was reduced in accordance with the breakpoint schedule provided below.

In excess of $1.0 billion up to $1.5 billion                            0.44
Over $1.5 billion                                                       0.36
</Table>

UBS Financial Services Inc. has further agreed to cap the Portfolio's aggregate
management and service fees so that the total of these does not exceed 0.50% of
the Portfolio's average daily net assets. This cap results in an effective
investment advisory and administration fee rate not to exceed 0.375% of the
Portfolio's average daily net assets.

    first day of each year reported, reinvestment of all dividends and other
    distributions, if any, at net asset value on the payable dates, and a sale
    at net asset value on the last day of each year reported. Returns do not
    reflect the deduction of taxes that a shareholder would pay on Portfolio
    distributions.
(2) During the period August 1, 2004 through June 30, 2005, UBS Financial

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
ERNST & YOUNG LLP

The Board of Directors/Trustees and Shareholders of UBS RMA:
Money Market Portfolio
U.S. Government Portfolio
Tax-Free Fund Inc.
California Municipal Money Fund
New York Municipal Money Fund
New Jersey Municipal Money Fund

We have audited the accompanying statements of net assets of the UBS RMA Money
Market Portfolio and UBS RMA U.S. Government Portfolio (two of the Funds
comprising UBS RMA Money Fund Inc.), UBS RMA Tax-Free Fund Inc., UBS RMA
California Municipal Money Fund and UBS RMA New York Municipal Money Fund (two
of the Funds comprising UBS Managed Municipal Trust) and UBS RMA New Jersey
Municipal Money Fund (the sole Fund comprising UBS Municipal Money Market
Series) (collectively, the "Funds") as of June 30, 2005, and the related
statements of operations for the year then ended, the statements of changes in
net assets for each of the two years in the period then ended and the financial
highlights for each of the five years in the period then ended. These financial
statements and financial highlights are the responsibility of the Funds'
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Funds' internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Funds' internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of June 30, 2005, by correspondence with the custodian and
others. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of UBS
RMA Money Market Portfolio, UBS RMA U.S. Government Portfolio, UBS RMA Tax-Free
Fund Inc., UBS RMA California Municipal Money Fund, UBS RMA New York Municipal

RESULTS OF SPECIAL SHAREHOLDERS MEETING--RMA MONEY MARKET PORTFOLIO

A Special Meeting of Shareholders of UBS RMA Money Market Portfolio (the "Fund")
of UBS RMA Money Fund Inc. (the "Company") was held on June 17, 2005 (reconvened
from the original meeting date of May 18, 2005). At the meeting, the
shareholders approved the adoption of a shareholder services plan with respect
to the Fund. (More information about the plan is contained above in the
"Subsequent Event" section at the end of the "Notes to Financial Statements.")
The shareholders also voted on a proposal to adopt an amendment to the Company's
Articles of Incorportion to permit its Board of Directors to reorganize the Fund
into a "master/feeder" structure. This would have allowed the Fund to invest all
or substantially all of its assets in another fund (a master fund) that has
substantially the same investment objectives, policies and restrictions, instead
of investing directly in portfolio securities. Although the overwhelming
majority of those shareholders who had cast a vote on the second proposal voted
in favor of the proposal, an insufficient number of votes were cast on the
proposal, and it was not approved. Votes were cast as indicated below:

1) To approve the adoption of a shareholder services plan with respect to the
   Fund:

<Table>
                     
            For:        4,771,684,779.117
            Against:      221,652,370.145
            Abstain:      643,125,532.948
</Table>

2) To approve an amendment to the Company's Articles of Incorporation to permit
   the Board of Directors to reorganize the Fund into a "master/feeder"
   structure:

<Table>
                     
            For:        4,663,609,228.914
            Against:      298,949,082.681
            Abstain:      673,904,370.615
</Table>

To the best of the Fund's knowledge, there were no "broker non-votes." (Broker
non-votes are shares held in street name for which the broker indicates that
instructions have not been received from the beneficial owners or other persons
entitled to vote and for which the broker does not have discretionary voting
authority.)

            $31,300, respectively.

            Fees included in the audit fees category are those associated with
            the annual audits of financial statements and services that are

            the audits of the financial statements, but not reported as audit
            fees, were approximately $2,712 and $2,593, respectively.

            paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X during the
            fiscal years indicated above.

                The registrant's Audit Committee ("audit committee") has adopted
                an "Audit Committee Charter (Amended and Restated as of May 12,
                2004)" (the "charter"). The charter contains the audit
                committee's pre-approval policies and procedures. Reproduced
                below is an excerpt from the charter regarding pre-approval
                policies and procedures:

                     The [audit ]Committee shall:

                     ...

                     2.  Pre-approve (a) all audit and permissible non-audit
                         services(1) to be provided to the Fund and (b) all
                         permissible non-audit services to be provided by the
                         Fund's independent auditors to UBS Global [AM] and any
                         Covered Service Providers, if the engagement relates
                         directly to the operations and financial reporting of
                         the Fund. In carrying out this responsibility, the
                         Committee shall seek periodically from UBS Global [AM]
                         and from the independent auditors a list of such audit
                         and permissible non-audit services that can be expected
                         to be rendered to the Fund, UBS Global [AM] or any
                         Covered Service Providers by the Fund's independent
                         auditors, and an estimate of the fees sought to be paid
                         in connection with such services. The Committee may
                         delegate its responsibility to pre-approve any such
                         audit and permissible non-audit services to a
                         sub-committee consisting of the Chairperson of the
                         Committee and two other members of the Committee as the
                         Chairperson, from time to time, may determine and
                         appoint, and such sub-committee shall

<Page>

                         report to the Committee, at its next regularly
                         scheduled meeting after the sub-committee's meeting,
                         its decision(s). From year to year, the Committee shall
                         report to the Board whether this system of pre-approval
                         has been effective and efficient or whether this
                         Charter should be amended to allow for pre-approval
                         pursuant to such policies and procedures as the
                         Committee shall approve, including the delegation of
                         some or all of the Committee's pre-approval
                         responsibilities to other persons (other than UBS
                         Global [AM] or the Fund's officers).

- ----------
                             (1) The Committee will not approve non-audit
                             services that the Committee believes may taint the
                             independence of the auditors. Currently,
                             permissible non-audit services include any
                             professional services (including tax services) that
                             are not prohibited services as described below,

                             other than those provided to the Fund in connection
                             with an audit or a review of the financial
                             statements of the Fund. Permissible non-audit
                             services may NOT include: (i) bookkeeping or other
                             services related to the accounting records or
                             financial statements of the Fund; (ii) financial
                             information systems design and implementation;
                             (iii) appraisal or valuation services, fairness
                             opinions or contribution-in-kind reports; (iv)
                             actuarial services; (v) internal audit outsourcing
                             services; (vi) management functions or human
                             resources; (vii) broker or dealer, investment

                             audit; and (ix) any other service the Public
                             Company Accounting Oversight Board determines, by
                             regulation, is impermissible.

                             Pre-approval by the Committee of any permissible
                             non-audit services is not required so long as: (i)
                             the aggregate amount of all such permissible
                             non-audit services provided to the Fund, UBS Global
                             [AM] and any service providers controlling,
                             controlled by or under common control with UBS
                             Global [AM] that provide ongoing services to the

                             to the independent auditors (during the fiscal year
                             in which the permissible non-audit services are
                             provided) by (a) the Fund, (b) its investment
                             adviser and (c) any entity controlling, controlled

                             during the fiscal year in which the services are
                             provided that would have to be approved by the
                             Committee; (ii) the permissible non-audit services
                             were not recognized by the Fund at the time of the
                             engagement to be non-audit services; and (iii) such
                             services are promptly brought to the attention of
                             the Committee and approved by the Committee (or its
                             delegate(s)) prior to the completion of the audit.
