DEAR SHAREHOLDER,

We are pleased to present you with the annual report for Managed High Yield Plus
Fund Inc. (the "Fund") for the fiscal year ended May 31, 2006.

PERFORMANCE

Over the fiscal year ended May 31, 2006, the Fund returned 11.16% on a net asset
value basis and 5.26% on a market price basis, outperforming its peer group
median and, on a net asset value basis, benchmark index. Over the same period,
the median returns for the Fund's peer group, the Lipper High Current Yield
Funds (Leveraged) were 9.20% and 4.71% on a net asset value and market price
basis, respectively. The Fund's benchmark, the Merrill Lynch US High Yield Cash
Pay Constrained Index (the "Index") returned 6.65% over the annual period. (For
more performance information, please refer to "Performance at a Glance" on page
5.)

The Fund continued to use leverage during the period, which helped performance
on an absolute basis. As of May 31, 2006 leverage accounted for 32.5% of the
Fund's total assets. While short-term rates rose over the period and increased
the Fund's borrowing costs, the leverage still had a positive effect on the
Fund's income during the fiscal year, as the yields on the Fund's longer-term
bonds more than offset the borrowing costs. Leverage magnifies returns on both
the upside and on the downside.

AN INTERVIEW WITH PORTFOLIO MANAGER MARIANNE ROSSI

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

A. The past 12 months were a rather turbulent time for the economy. During the
   summer months in 2005, a devastating and record-breaking hurricane season
   drove already high energy prices even higher. By Labor

MANAGED HIGH YIELD PLUS FUND INC.

   Day weekend, in the immediate wake of Hurricane Katrina, crude oil prices
   had topped $70 per barrel and gas prices averaged more than $3.00 a gallon
   nationwide. Consumer confidence plummeted in the months that followed, and
   during the fourth quarter of 2005, lackluster consumer spending drove gross
   domestic product (GDP) down to a 1.7% growth rate--a three-year low.

   By the end of the first quarter of 2006, however, a number of these
   indicators reversed direction. Consumer confidence rebounded sharply
   beginning in November 2005, and in April 2006 hit a four-year high. Final
   data put GDP growth in the first quarter this year at 5.6%--a three-year
   high. Unemployment trended steadily downward throughout the Fund's fiscal
   year, hitting 4.6% in May, the lowest it has been since 2001. Inflation,
   meanwhile, remained fairly benign for much of the period, but has raised
   some concern among economists recently.

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

A. The Fed continued its tightening campaign, raising short-term rates eight
   times during the period and once after the period ended, bringing the
   federal funds rate to 5.25%. (The federal funds rate is the interest rate
   banks charge each other for overnight loans). In fact, the Fed has hiked
   rates at 17 consecutive meetings dating back to June 2004. The market
   consensus seems to be that the Fed may be near the end of this current
   tightening policy. While we can't be certain exactly when the Fed will pause
   or end its current policy, we believe it is unlikely that the Fed will
   continue to hike rates for the remainder of 2006, as was the case in 2005.

Q. HOW DID HIGH YIELD BONDS PERFORM DURING THE REPORTING PERIOD?

A. The high yield market performed fairly well during the past year, despite
   a number of highly publicized downgrades and bankruptcies. Over the course of
   the year, Delta Airlines and Northwest Airlines both filed for bankruptcy,
   which put considerable pressure on the entire airline industry as the market
   braced for future filings. Delphi Automotive, an auto parts manufacturer,
   also filed for Chapter 11 protection. GM and Ford were downgraded to
   noninvestment-grade status, making them two of the largest issuers in the
   high-yield debt sector. The automaker and auto parts sector posted fairly
   solid returns during the past year, however, with both GM and Ford performing
   well after their downgrade in credit quality.

   By historical measures, default rates have been quite low, while new bond
   issuance has been relatively limited. Also, corporate earnings were quite
   strong during the reporting period. This combination created a

- --------------------------------------------------------------------------------
2


MANAGED HIGH YIELD PLUS FUND INC.

   fairly stable high-yield market over the period, with strong demand and
   limited supply. As a result, credit spreads (the difference in yield between
   noninvestment-grade bonds and similarly dated treasuries) have been tight
   compared to the historical average.

Q. HOW DID YOU POSITION THE FUND'S PORTFOLIO?

A. In terms of credit quality, for several months we have been repositioning the
   portfolio, de-emphasizing CCC-rated securities, which performed quite well
   for the Fund during the fiscal year, and adding to our positions in B-rated
   bonds. We believe that the economy will remain stable over the coming months,
   and that given the recent strong performance of the CCC sector, B-rated
   securities generally appear more attractive from a valuation standpoint.

Q. WHICH INDUSTRIES DID YOU FIND ATTRACTIVE DURING THE REPORTING PERIOD?

A. Three of our largest overweight positions were in the chemicals, restaurants
   and gaming industries. We found all three industries to offer some attractive
   investment opportunities from a valuation perspective relative to the overall
   high yield market. Within the chemicals industry, we found a number of
   companies that exhibited what we believed were indicators of solid management
   and well-run operations. We generally found the same to be true within the
   gaming industry. Issue selection within these industries was quite strong,
   making these sectors three of the Fund's top contributors to performance.

Q. WHICH INVESTMENTS DID NOT MEET YOUR EXPECTATIONS?

A. We held a fairly large position in the containers industry, which detracted
   from total returns during the year. The containers industry as a whole
   suffered from higher raw materials prices during the period, which cut into
   companies' profitability. Within the paper industry, weak demand and a strong
   Canadian dollar hurt performance.

Q. WHAT IS YOUR OUTLOOK FOR THE ECONOMY AND THE HIGH YIELD MARKET?

A. We believe the economy will continue expanding while the Fed maintains its
   hawkish stance on inflation. Against that backdrop, fundamentals for the
   high-yield market appear firm. Although US mutual fund outflows have been
   high in the high-yield sector, investors outside the US have helped to buoy
   the market, and we feel that much of the positive factors at work in the
   market are already reflected in security prices. We believe tight credit
   spreads are likely to make active issue selection essential to performance,
   as finding attractive values may become more challenging as the year
   progresses.

* Since inception returns for the Fund are calculated from the date of the
  Fund's inception on June 26, 1998. Inception returns for the Lipper High
  Current Yield Funds (Leveraged) median and Merrill Lynch US High Yield Cash
  Pay Constrained Index are calculated from the month-end closest to the Fund's
  inception: June 30, 1998.

Past performance does not predict future performance. The return and value of an
investment will fluctuate so that an investor's shares, when sold, may be worth
more or less than their original cost. Fund net asset value ("NAV") return
assumes, for illustration only, that dividends were reinvested at the net asset
value on the payable dates. NAV and market price returns for periods of less
than one year have not been annualized. Returns do not reflect the deduction of
taxes that a shareholder would pay on Fund distribution or the sale of Fund
shares.

MANAGED HIGH YIELD PLUS FUND INC.

NOTES TO FINANCIAL STATEMENTS

ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Managed High Yield Plus Fund Inc. (the "Fund") was incorporated in Maryland on
April 24, 1998, and is registered with the Securities and Exchange Commission
under the Investment Company Act of 1940, as amended ("1940 Act"), as a
closed-end diversified management investment company. The Fund's primary
investment objective is to seek high income. Its secondary objective is to seek
capital appreciation.

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

The preparation of financial statements in accordance with US generally accepted
accounting principles requires the Fund's 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 OF INVESTMENTS--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 last reported
sale prices, current market quotations or valuations from computerized "matrix"
systems that derive values based on comparable securities. A matrix system
incorporates parameters such as security quality, maturity and coupon, and/or
research and evaluations by its staff, including review of broker-dealer market
price quotations, if available, in determining the valuation of the portfolio
securities. Securities traded in the over-the-counter ("OTC") market and listed
on The Nasdaq Stock Market, Inc. ("Nasdaq") normally are valued at the NASDAQ
Official Closing Price. Other OTC securities are valued at the last bid price
available on the valuation date prior to valuation. Securities which are listed
on US and foreign stock exchanges normally are valued at the last sale price on
the day the securities are valued or, lacking any sales on such day, at the last
available bid price. In cases where securities are traded on more than one
exchange, the securities are valued on the exchange designated as the primary
market by UBS Global Asset Management (Americas) Inc., the investment manager
and administrator of the Fund. If a market value is not available from an
independent pricing

NOTES TO FINANCIAL STATEMENTS

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 of
Directors (the "Board"). Various factors may be reviewed in order to make a good
faith determination of a security's fair value. These factors include, but are
not limited to, the type and cost of the security; contractual or legal
restrictions on resale of the security; relevant financial or business
developments of the issuer; actively traded similar or related securities;
conversion or exchange rights on the security; related corporate actions; and
changes in overall market conditions. If events occur that materially affect the
value of securities (particularly non-US securities) between the close of
trading in those securities and the close of regular trading on the New York
Stock Exchange ("NYSE"), the securities are fair valued. 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. All
investments quoted in foreign currencies will be valued daily in US dollars on
the basis of the foreign currency exchange rates prevailing at the time such
valuation is determined by the Fund's custodian.

REPURCHASE AGREEMENTS--The Fund 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 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. The underlying collateral is valued daily 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
Fund generally has the right to liquidate the collateral and apply the proceeds
in satisfaction of the obligation. 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 counterparty insolvency. If the seller
(or seller's guarantor, if any) becomes insolvent, the Fund 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 Fund may participate in
joint repurchase agreement transactions with other funds managed, advised or
sub-advised by UBS Global Asset Management (Americas) Inc.

                                                                              21


MANAGED HIGH YIELD PLUS FUND INC.

NOTES TO FINANCIAL STATEMENTS

INVESTMENT TRANSACTIONS AND INVESTMENT INCOME--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. Dividend income is recorded on the ex-dividend
date ("ex-date"). Discounts are accreted and premiums are amortized as
adjustments to interest income and the identified cost of investments.

DIVIDENDS AND DISTRIBUTIONS--Dividends and distributions to shareholders are
recorded on the ex-date. The amount of dividends and distributions is determined
in accordance with federal income tax regulations, which may differ from US
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 Fund to meet their
obligations may be affected by economic developments, including those particular
to a specific industry, country or region. In addition, the Fund's use of
leverage creates greater volatility in the Fund's net asset value and market
price of its shares.

INVESTMENT MANAGER AND ADMINISTRATOR

UBS Global Asset Management (US) Inc. ("UBS Global AM--US") served as the Fund's
investment manager and administrator from May 1, 2005, until April 1, 2006. On
April 1, 2006, the Fund's Investment Management Contract ("Management Contract")
was transferred from UBS Global AM--US to UBS Global Asset Management (Americas)
Inc. ("UBS Global AM--Americas").

The transfer of the Management Contract between sister companies occurred in
connection with an internal reorganization involving UBS Global AM--US and UBS
Global AM--Americas. The Fund's Board of Directors approved the transfer of the
Management Contract effective April 1, 2006. All of the personnel of UBS Global
AM--US who previously provided investment management services to the Fund
continue to provide investment management services to the Fund as employees of
UBS Global AM--Americas. UBS Global AM--Americas has the same contractual
rights and responsibilities under the Management Contract as those previously
held by UBS Global AM--US. UBS Global AM--US and UBS Global AM--Americas are
both indirect wholly owned subsidiaries of UBS AG.

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

MANAGED HIGH YIELD PLUS FUND INC.

NOTES TO FINANCIAL STATEMENTS

In accordance with the Management Contract, the Fund paid UBS Global
AM--Americas (or UBS Global AM--US for periods prior to April 1, 2006) an
investment management and administration fee, which was accrued weekly and paid
monthly, at the annual rate of 0.70% of the Fund's average weekly total assets
minus liabilities other than the aggregate indebtedness constituting leverage.

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
director of the Fund. The Fund has been informed that Professor Feldberg's role
at Morgan Stanley does not involve matters directly affecting any UBS funds.
Portfolio transactions are executed through Morgan Stanley based on that firm's
ability to provide best execution of the transactions. During the year ended May
31, 2006, the Fund purchased and sold certain securities (e.g., fixed income
securities) in principal trades with Morgan Stanley having an aggregate value of
$28,644,855. 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.

BORROWINGS

The Fund has a $175 million committed credit facility (the "Facility"). Under
the terms of the Facility, the Fund borrows at prevailing commercial paper rates
in effect at the time of borrowing plus facility and administrative fees. In
addition, the Fund pays a liquidity fee on the entire amount of the Facility.
The Fund may borrow up to 331/3% of its total assets up to the committed amount.
In accordance with the terms of the Facility, the Fund has pledged assets in the
amount of $406,838,697 on May 31, 2006 as collateral for the bank loan.

For the year ended May 31, 2006, the Fund borrowed a daily average balance of
$139,169,863 at a weighted average borrowing cost of approximately 4.55%.

PURCHASES AND SALES OF SECURITIES

For the year ended May 31, 2006, aggregate purchases and sales of portfolio
securities, excluding short-term securities, were $172,091,939 and $166,467,022,
respectively.

FEDERAL TAX STATUS

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

The tax character of distributions paid during the fiscal years ended May 31,
2006 and May 31, 2005, were as follows:



DISTRIBUTIONS PAID FROM:                        2006                       2005

===================================================================================


At May 31, 2006, the Fund had a net capital loss carryover of $373,150,238.
This loss carryforward is available as a reduction, to the extent provided in
the regulations, of future net realized capital gains, and will expire as
follows: $13,100,516 in 2007; $50,099,935 in 2008; $71,221,921 in 2009;
$71,854,329 in 2010; $95,911,016 in 2011; $27,212,620 in 2012; $13,297,624 in
2013; and $30,452,277 in 2014. To the extent that such losses are used to offset
future net realized capital gains, it is probable these gains will not be
distributed. Also, in accordance with US Treasury regulations, the Fund has
elected to defer $15,256,212 of net realized capital losses arising after
October 31, 2005. Such losses are treated for tax purposes as arising
on June 1, 2006.

RIGHTS OFFERING

During the year ended May 31, 2005, the Fund issued 16,499,670 shares in
connection with a rights offering of the Fund's common stock. Shareholders of
record on January 31, 2005, were issued one non-transferable right for each
share of common stock owned, entitling shareholders the opportunity to acquire
one newly issued share of common stock for every three rights held. The rights
offering commenced on January 31, 2005 and expired on February 28, 2005. The
subscription price per share was the greater of (i) the net asset value ("NAV")
per share on February 28, 2005 (the "expiration date") or (ii) 95% of the volume
weighted average share price of a share on the New York Stock Exchange on the
expiration date and the four preceding business days. The subscription price of
the offer was $5.41 per share, which was greater than the NAV per share of $5.37
on the expiration date. Offering costs attributed to the rights offering in the

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ERNST & YOUNG LLP

The Board of Directors and Shareholders
Managed High Yield Plus Fund Inc.

We have audited the accompanying statement of assets and liabilities of Managed
High Yield Plus Fund Inc. (the "Fund"), including the portfolio of investments,
as of May 31, 2006, and the related statements of operations and cash flows 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 Fund's 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 Fund's 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 Fund's 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 May 31, 2006, by correspondence with the custodian and
brokers. 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
Managed High Yield Plus Fund Inc. at May 31, 2006, the results of its operations
and its cash flows for the year then ended, the changes in its 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, in conformity with US generally
accepted accounting principles.

DIVIDEND REINVESTMENT PLAN

The Fund's Board has established a Dividend Reinvestment Plan (the "Plan")
under which all shareholders whose shares are registered in their own names, or
in the name of UBS Financial Services Inc., or its nominee, will have all
dividends and other distributions on their shares automatically reinvested in
additional shares, unless such shareholders elect to receive cash. Shareholders
who elect to hold their shares in the name of another broker or nominee should
contact such broker or nominee to determine whether, or how, they may
participate in the Plan. The ability of such shareholders to participate in the
Plan may change if their shares are transferred into the name of another broker
or nominee.

A shareholder may elect not to participate in the Plan or may terminate
participation in the Plan at any time without penalty, and shareholders who have
previously terminated participation in the Plan may rejoin it at any time.
Changes in elections must be made in writing to the Fund's transfer agent and
should include the shareholder's name and address as they appear on that share
certificate or in the transfer agent's records. An election to terminate
participation in the Plan, until such election is changed, will be

- --------------------------------------------------------------------------------
                                                                              29


MANAGED HIGH YIELD PLUS FUND INC.

GENERAL INFORMATION (UNAUDITED)

deemed an election by a shareholder to take all subsequent distributions in
cash. An election will be effective only for distributions declared and having a
record date at least ten days after the date on which the election is received.

The transfer agent will serve as agent for the shareholders in administering the
Plan. After the Fund declares a dividend or determines to make any other
distribution, the transfer agent, as agent for the participants, receives the
cash payment. Whenever the Fund declares an income dividend or a capital gain
distribution (collectively referred to in this section as "dividends") payable
either in shares or in cash, non-participants in the Plan will receive cash and
participants in the Plan will receive the equivalent in shares. The transfer
agent will acquire shares for the participants' accounts, depending upon the
circumstances described below, either (i) through receipt of unissued but
authorized shares from the Fund ("newly issued shares") or (ii) by purchase of
outstanding shares on the open market, on the NYSE or elsewhere ("open-market
purchases"). If, on the dividend payment date, the net asset value per share is
equal to or less than the market price per share, plus estimated brokerage
commissions (such condition being referred to herein as "market premium"), the
transfer agent will invest the dividend amount in newly issued shares on behalf
of the participants. The number of newly issued shares to be credited to each
participant's account will be determined by dividing the dollar amount of the
dividend by the net asset value per share (but in no event less than 95% of the
then current market price per share) on the date the shares were issued. If, on
the dividend payment date, the net asset value per share is greater than the
market value per share, plus estimated brokerage commissions (such condition
being referred to herein as "market discount"), the transfer agent will invest
the dividend amount in shares acquired on behalf of the participants in
open-market purchases. The number of outstanding shares purchased with each
distribution for a particular shareholder equals the result obtained by dividing
the amount of the distribution payable to that shareholder by the average price
per share (including applicable brokerage commissions) that the transfer agent
was able to obtain in the open market.

In the event of a market discount on the dividend payment date, the transfer
agent will have until the last business day before the next date on which the
shares trade on an "ex-dividend" basis, but in no event more than 30 days
after the dividend payment date (the "last purchase date"), to invest the
dividend amount in shares acquired in open-market purchases. It is contemplated
that the Fund will pay monthly income dividends. Therefore, the period during
which open-market purchases can be made will exist only from the payment date of
the dividend through the date before the next

- --------------------------------------------------------------------------------
30


MANAGED HIGH YIELD PLUS FUND INC.

GENERAL INFORMATION (UNAUDITED)

"ex-dividend" date, which typically will be approximately ten business days.
If, before the transfer agent has completed its open-market purchases, the
market price of a share, plus estimated brokerage commissions, exceeds the net
asset value per share, the average per share purchase price paid by the transfer
agent may exceed the Fund's net asset value per share, resulting in the
acquisition of fewer shares than if the dividend had been paid in newly issued
shares on the dividend payment date. Because of the foregoing difficulty with
respect to open-market purchases, the Plan provides that, if the transfer agent
is unable to invest the full dividend amount in open-market purchases during the
purchase period or if the market discount shifts to a market premium during the
purchase period, the transfer agent will cease making open-market purchases and
will invest the uninvested portion of the dividend amount in newly issued shares
at the close of business on the earlier of the last purchase date or the first
day during the purchase period on which the net asset value per share equals or
is less than the market price per share, plus estimated brokerage commissions.
The transfer agent will maintain all shareholder accounts in the Plan and will
furnish written confirmations of all transactions in the accounts, including
information needed by shareholders for personal and tax records. Shares in the
account of each Plan participant will be held by the transfer agent in
non-certificated form in the name of the participant, and each shareholder's
proxy will include those shares purchased pursuant to the Plan. There will be no
charge to participants for reinvesting dividends. However, each participant will
pay a pro rata share of brokerage commissions incurred with respect to the
transfer agent's open market purchases of shares in connection with the
reinvestment of dividends. The automatic reinvestment of dividends in shares
does not relieve participants of any income tax that may be payable on such
dividends.

Shareholders who participate in the Plan may receive benefits not available to
shareholders who do not participate in the Plan. If the market price (plus
commissions) of the shares is above their net asset value, participants in the
Plan will receive shares at less than they could otherwise purchase them and
will have shares with a cash value greater than the value of any cash dividends
they would have received on their shares. If the market price plus commissions
is below the net asset value, participants will receive dividends in shares with
a net asset value greater than the value of any cash dividends they would have
received on their shares. However, there may be insufficient shares available in
the market to distribute dividends in shares at prices below the net asset
value. Also, since the Fund does not redeem its shares, the price on resale may
be more or less than the net asset value.

GENERAL INFORMATION (UNAUDITED)

Experience under the Plan may indicate that changes are desirable. Accordingly,
the Fund reserves the right to amend or terminate the Plan with respect to any
dividend or other distribution if notice of the change is sent to Plan
participants at least 30 days before the record date for such distribution. The
Plan also may be amended or terminated by the transfer agent by at least 30 days
written notice to all Plan participants. Additional information regarding the
Plan may be obtained from, and all correspondence concerning the Plan should be
directed to, the transfer agent at PFPC Inc., P.O. Box 8030, Boston,
Massachusetts 02266-8030. For further information regarding the Plan, you may

BOARD APPROVAL OF INVESTMENT MANAGEMENT AND
ADMINISTRATION AGREEMENT (UNAUDITED)

BACKGROUND--At a meeting of the board of Managed High Yield Plus Fund Inc. (the
"Fund") on February 8, 2006, the members of the board, including the board
members who are not "interested persons" of the Fund ("Independent Directors"),
as defined in the Investment Company Act of 1940, as amended, considered and
approved the transfer of the current Investment Management and Administration
Agreement between the Fund and UBS Global Asset Management (US) Inc. ("UBS
Global AM") to UBS Global Asset Management (Americas) Inc. ("UBS Global
Americas"), an affiliate of UBS Global AM. The board received information and
materials about the proposed transfer both at its November 2005 meeting and at
its February 2006 meeting. In considering the approval of the transfer of the
Investment Management and Administration Agreement (such transfer referred to as
the "New Investment Management and Administration Agreement"), the board
reviewed a memorandum from UBS Global AM explaining the reasons for the proposed
transfer, including that the transfer would result in management efficiencies
and eliminate the duplication of functions that had resulted from having two
registered investment advisors, UBS Global AM and UBS Global Americas, providing
investment advisory services to the UBS funds. The board also reviewed material
provided by UBS Global AM on UBS Global Americas, including that the current
portfolio manager for the Fund would not change as a result of the transfer from
UBS Global AM to UBS Global Americas. The board also noted management's
explanation that any expenses resulting from the transfer would be borne by UBS
Global AM, and not the Fund. The board also received and reviewed a draft of an
opinion to be provided by Dechert LLP, counsel to the Fund, that the proposed
transfer would not be considered an "assignment" of the existing investment
advisory contract under the Investment Company Act of 1940, as amended, because
(1) there would be no change of actual control of the investment advisor to the
Fund; (2) there would be no change of management of the investment advisor to
the Fund; (3) the nature, quality and extent of the investment advisory services
provided by UBS Global AM under the current Investment Management and
Administration Agreement would not change as a result of the transfer; (4) the
transfer would not result in any change in the fundamental investment processes,
investment strategies or investment techniques currently employed by UBS Global
AM portfolio managers or other investment professionals in providing services to
the Fund; and (5) there would be no change to any of the material terms of the
Investment Management and Administration Agreements as a result

MANAGED HIGH YIELD PLUS FUND INC.

BOARD APPROVAL OF INVESTMENT MANAGEMENT AND
ADMINISTRATION AGREEMENT (UNAUDITED)

of the transfer. The board took note of its knowledge of UBS Global AM and its
affiliates, including UBS Global Americas, and the current Investment Management
and Administration Agreement for the Fund, including the extensive materials it
had reviewed at its annual contract renewal meeting in the summer of 2005 for
the Fund, and noted that it had at that time received a memorandum from its
independent legal counsel discussing, among other things, the duties of board
members in considering approval of advisory and administration agreements.

In its consideration of the approval of the New Investment Management and
Administration Agreement, the board considered the following factors:

NATURE, EXTENT AND QUALITY OF THE SERVICES UNDER THE NEW INVESTMENT MANAGEMENT
AND ADMINISTRATION AGREEMENT--The board took note that at its last annual
contract renewal meeting for the Fund, in connection with its review of the
Fund's advisory and distribution agreements, it had received and considered
extensive information regarding the nature, extent and quality of management
services generally provided to the Fund by UBS Global AM under the Investment
Management and Administration Agreement, and a description of the administrative
and other services rendered to the Fund and its shareholders by UBS Global AM
and UBS Global AM's role in coordinating providers of other services to the
Fund, including custody, accounting and transfer agency services. The board
considered management's explanation that UBS Global Americas would provide
identical services under the New Investment Management and Administration
Agreement as were provided by UBS Global AM under the current Investment
Management and Administration Agreement. The board's evaluation of the services
to be provided by UBS Global Americas to the Fund took into account the board's
knowledge and familiarity gained as board members of funds in the UBS New York
fund complex, including the scope and quality of investment management and other
capabilities and the quality of administrative and other services, and
considered that based on the materials presented to them these services would
remain the same. The board also considered, based on its knowledge of UBS Global
AM and UBS Global Americas, the financial resources available to UBS Global
Americas and its parent organization, UBS AG, one of the leading financial
services companies in the world.

The board concluded that, overall, it was satisfied with the nature, extent and
quality of services expected to be provided to the Fund under the New Investment
Management and Administration Agreement.

MANAGEMENT FEES--The board noted that the current contractual management fee for
the Fund under the current Investment Management and Administration Agreement
was not proposed to be changed under the New Investment Management and
Administration Agreement. The board also considered that at its most recent
annual contract renewal meeting during the summer of 2005 it had received and
reviewed information on the contractual management fee payable by the Fund to
UBS Global AM, including information of management fees paid by comparable
funds. The board recognized that the current fee arrangements would not change
as a result of the transfer.

Taking all of the above into consideration, the board determined that the
proposed contractual management fee was reasonable in light of the nature,
extent and quality of the services proposed to be provided to the Fund under the
New Investment Management and Administration Agreement.

FUND PERFORMANCE--The board took into consideration the reports on Fund
performance received by the board at each meeting and the more extensive review
and discussion of Fund performance at its most recent annual contract renewal
meeting. The board also noted that the transfer would not result in any change
in the fundamental investment processes, investment strategies or investment
techniques of the Fund and that no changes in the current Fund personnel
overseeing Fund management were proposed or anticipated as a result of the
transfer.

Based on its prior review and the more updated performance information provided,
the board concluded that the Fund's investment performance was satisfactory.

ADVISOR PROFITABILITY--As UBS Global Americas would be a new advisor to the
Fund, profitability of UBS Global Americas in providing services to the Fund was
not a primary factor considered by the board. The board did note that at its
most recent annual contract renewal meeting it received and considered a
profitability analysis of UBS Global AM and its affiliates in providing services
to the Fund and had determined at that time that UBS Global AM's profitability
was considered not excessive in light of the nature, extent and quality of the
services provided to the Fund. The board also recognized that the management fee
would not change as a result of the transfer and the services provided to the
Fund by UBS Global Americas would be identical to those currently provided by
UBS Global AM, making the profitability data received at its last contract
renewal meeting still of

some relevance. UBS Global AM also noted management's explanation that a
significant benefit of the transfer of the Investment Management and
Administration Agreement to UBS Global Americas was to reduce a regulatory
capital requirement imposed on UBS Global AM, which was expected to permit the
eventual transfer of certain financial assets owned by UBS Global AM to satisfy
regulatory requirements to other parts of UBS AG for other corporate purposes.

ECONOMIES OF SCALE--The board noted that it had previously considered whether
economies of scale in the provision of services to the Fund would be passed
along to the shareholders during its most recent consideration of the annual
renewal of the Investment Management and Administration Agreement and did not
see the need to reconsider this factor again in the context of the transfer of
the agreement to a sister investment advisor.

OTHER BENEFITS TO UBS GLOBAL AMERICAS--The board considered other benefits
received by UBS Global Americas and its affiliates as a result of its proposed
relationship with the Fund, including the potential opportunity to offer
additional products and services to Fund shareholders. The board also considered
the benefits to be realized when certain assets of UBS Global AM were freed from
certain regulatory requirements and were available to be paid as a dividend from
one part of UBS AG to another part of UBS AG for such purposes as UBS AG deemed
appropriate.

In light of the costs of providing investment management, administrative and
other services to the Fund and UBS Global America's expected ongoing commitment
to the Fund, the profits and other ancillary benefits that UBS Global Americas
and its affiliates received or would receive were considered reasonable.

In light of all of the foregoing, the board approved the New Investment
Management and Administration Agreement for the Fund.

No single factor reviewed by the board was identified by the board as the
principal factor in determining whether to approve the New Investment Management
and Administration Agreement. The Independent Directors were advised by separate
independent legal counsel throughout the process. The board discussed the
proposed approval of the New Investment Management and Administration Agreement
in a private session with their independent legal counsel at which no
representatives of UBS Global AM or UBS Global Americas were present.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.
- -----------------------------------------------

  (a)  Audit Fees:
       ----------
       For the fiscal years ended May 31, 2006 and May 31, 2005, the aggregate
       Ernst & Young LLP (E&Y) audit fees for professional services rendered to
       the registrant were approximately $51,400 and $67,300, respectively.

       Fees included in the audit fees category are those associated with the
       annual audits of financial statements and services that are normally
       provided in connection with statutory and regulatory filings.

  (b)  Audit-Related Fees:
       ------------------
       In each of the fiscal years ended May 31, 2006 and May 31, 2005, the
       aggregate audit-related fees billed by E&Y for services rendered to the
       registrant that are reasonably related to the performance of the audits
       of the financial statements, but not reported as audit fees, were
       approximately $22,212 and $20,500, respectively.

       Fees included in the audit-related category are those associated with
       (1) the reading and providing of comments on the 2005 and 2004
       semiannual financial statements, (2) review of the consolidated 2004 and
       2003 reports on the profitability of the UBS Funds to UBS Global Asset
       Management (US) Inc. ("UBS Global AM") and its affiliates to assist the
       board members in their annual advisory/administration contract reviews
       and (3) agreed upon procedures for a revolving line of credit for the
       Fund's fiscal years ended 2005 and 2004.

       There were no audit-related fees required to be approved pursuant to
       paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X during the fiscal
       years indicated above.

  (c)  Tax Fees:
       --------


       In each of the fiscal years ended May 31, 2006 and May 31, 2005, the
       aggregate tax fees billed by E&Y for professional services rendered to
       the registrant were approximately $14,950 and $14,800, respectively.

       Fees included in the tax fees category comprise all services performed
       by professional staff in the independent accountant's tax division
       except those services related to the audits. This category comprises
       fees for review of tax compliance, tax return preparation and excise tax
       calculations.

       There were no tax fees required to be approved pursuant to paragraph
       (c)(7)(ii) of Rule 2-01 of Regulation S-X during the fiscal years
       indicated above.

  (d)  All Other Fees:
       --------------
       In each of the fiscal years ended May 31, 2006 and May 31, 2005, there
       were no fees billed by E&Y for products and services, other than the
       services reported in Item 4(a)-(c) above, rendered to the registrant.

       Fees included in the all other fees category would consist of services
       related to internal control reviews, strategy and other consulting,
       financial information systems design and implementation, consulting on
       other information systems, and other tax services unrelated to the
       registrant.

       There were no "all other fees" required to be approved pursuant to
       paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X during the fiscal
       years indicated above.

   (e) (1) Audit Committee Pre-Approval Policies and Procedures:
           ----------------------------------------------------
           The registrant's Audit Committee ("audit committee") has adopted an
           "Audit Committee Charter (Amended and Restated as of May 12, 2004 -
           Revised as of February 3, 2006)" (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 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, provided to the Fund by the
                       independent auditors, 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 adviser or investment banking
                       services; (viii) legal services and expert services
                       unrelated to the 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 Fund ("Covered Service
                       Providers") constitutes not more than 5% of the total
                       amount of revenues paid 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 by, or under common control with the
                       investment adviser that provides ongoing services to
                       the Fund 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.

   (e) (2) Services approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of
           Regulation S-X:

ITEM 6. SCHEDULE OF INVESTMENTS.

Included as part of the report to shareholders filed under Item 1 of this form.

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
- -------------------------------------------------------------------------
MANAGEMENT INVESTMENT COMPANIES.
- --------------------------------

The registrant's Board of Directors believes that the voting of proxies on
securities held by the registrant is an important element of the overall
investment process. As such, the Board has delegated the responsibility to vote
such proxies to the registrant's advisor. Following is a summary of the proxy
voting policy of the advisor.

CORPORATE GOVERNANCE PHILOSOPHY, VOTING GUIDELINES AND POLICY SUMMARY

The proxy voting policy of UBS Global AM is based on its belief that voting
rights have economic value and must be treated accordingly. Generally, UBS
Global AM expects the boards of directors of companies issuing securities held
by its clients to act as stewards of the financial assets of the company, to
exercise good judgment and practice diligent oversight with the management of
the company. While there is no absolute set of rules that determines appropriate
corporate governance under all circumstances and no set of rules will guarantee
ethical behavior, there are certain benchmarks, which, if substantial progress
is made toward, give evidence of good corporate governance. UBS Global AM may
delegate to an independent proxy voting and research service the authority to
exercise the voting rights associated with certain client holdings. Any such
delegation shall be made with the direction that the votes be exercised in
accordance with UBS Global AM's proxy voting policy.

When UBS Global AM's view of a company's management is favorable, UBS Global AM
generally supports current management initiatives. When UBS Global AM's view is
that changes to the management structure would probably increase shareholder
value, UBS Global AM may not support existing management proposals. In general,
UBS Global AM (1) opposes proposals which act to entrench management; (2)
believes that boards should be independent of company management and composed of
persons with requisite skills, knowledge and experience; (3) opposes structures
which impose financial constraints on changes in control; (4) believes
remuneration should be commensurate with responsibilities and performance; and
(5) believes that appropriate steps should be taken to ensure the independence
of auditors.

UBS Global AM has implemented procedures designed to identify whether it has a
conflict of interest in voting a particular proxy proposal, which may arise as a
result of its or its affiliates' client relationships,


marketing efforts or banking and broker/dealer activities. To address such
conflicts, UBS Global AM has imposed information barriers between it and its
affiliates who conduct banking, investment banking and broker/dealer activities
and has implemented procedures to prevent business, sales and marketing issues
from influencing our proxy votes. Whenever UBS Global AM is aware of a conflict
with respect to a particular proxy, its appropriate local corporate governance
committee is required to review and agree to the manner in which such proxy is
voted.

       management of other accounts. Further information is provided below.

   (a) (2) (ii) (A) Registered Investment Companies

                The portfolio manager is responsible for 3 additional Registered
       Investment Companies having $341,814,846 in total aggregate assets.

   (a) (2) (ii) (B) Other Pooled Investment Vehicles

                The portfolio manager is responsible for 23 Other Pooled
       Investment Vehicles having $1,307,254,464 in total aggregate assets.

   (a) (2) (ii) (C) Other Accounts

                The portfolio manager is responsible for 9 Other Accounts having
       $83,524,074 in total aggregate assets.

   (a) (2) (iii) None of these accounts is subject to an advisory fee based on
       the performance of the account.


   (a) (2) (iv) Conflicts.

                The management of the registrant and other accounts by a
       portfolio manager could result in potential conflicts of interest if the
       registrant and other accounts have different objectives, benchmarks and
       fees because the portfolio manager and his team must allocate time and
       investment expertise across multiple accounts, including the registrant.
       The portfolio manager and his team manage the registrant and other
       accounts utilizing an approach that groups similar accounts within a
       model portfolio. The Advisor manages accounts according to their
       respective objectives, including where possible, those accounts that
       have specific investment restrictions.  Accordingly, portfolio holdings,
       position sizes, and industry and sector exposures tend to be similar
       across accounts, which may minimize the potential for conflicts of
       interest.

                If a portfolio manager identifies a limited investment
       opportunity that may be suitable for more than one account, the
       registrant may not be able to take full advantage of that opportunity
       due to an allocation of filled purchase or sale orders across all
       eligible model portfolios and accounts. To deal with these situations,
       the Advisor has adopted procedures for allocating portfolio trades
       across multiple accounts to provide fair treatment to all accounts.

                The management of personal accounts by a portfolio manager may
       also give rise to potential conflicts of interest. The Advisor and the
       registrant have adopted a Code of Ethics that governs such personal
       trading, but there is no assurance that the Code will adequately address
       all such conflicts.

       (Information for Mr. Shu Yang Tan in Item 8 (a) (2) is provided as of
       July 21, 2006, as he is the new portfolio manager for the registrant.)

   (a) (3) Compensation.

                The compensation received by portfolio managers at UBS Global
       AM, including Mr. Shu Yang Tan, includes a base salary and incentive
       compensation as detailed below. Overall compensation can be grouped into
       three categories: base salary, annual bonuses and UBS AG equity. Base
       salary is fixed compensation used to recognize the experience, skills
       and knowledge that the investment professionals bring to their roles.
       Annual bonuses are correlated with performance and are based on three
       components: 1) the firm's overall business success; 2) the performance
       of the respective asset class and/or investment mandate; and 3) an
       individual's specific contribution to the firm's results. Senior
       investment professionals may receive a portion of their annual
       performance-based incentive in the form of deferred or restricted UBS AG
       shares or employee stock options. Broader equity share ownership is
       encouraged for all employees through "Equity Plus." This long-term
       incentive program gives employees the opportunity to purchase UBS stock
       with after-tax funds from their bonus or salary. Two UBS stock options
       are given for each share acquired and held for two years.


       (This information for Mr. Shu Yang Tan is provided as of July 21, 2006,
       as he is the new portfolio manager for the registrant.)

   (a) (4) Dollar Range of Securities of Registrant Beneficially Owned by
       Portfolio Manager: None.

       (This information for Mr. Shu Yang Tan is provided as of July 21, 2006,
