PROXY STATEMENT
-------------------

ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON SEPTEMBER 21, 2000

This statement is furnished to the shareholders of Managed High Yield Plus
Fund Inc. ('Fund') in connection with the board of directors' solicitation of
proxies to be used at the annual meeting of the shareholders of the Fund to be
held on September 21, 2000, or any adjournment or adjournments thereof. This
proxy statement and the related proxy card will first be mailed to shareholders
on or about July 31, 2000.

A majority of the shares outstanding on September 21, 2000, represented in
person or by proxy, must be present for the transaction of business at the
meeting. In the event that a quorum is not present at the annual meeting, or if
a quorum is present at the annual meeting but sufficient votes to approve any of
the proposals are not received, the persons named as proxies may propose one or
more adjournments of the annual meeting to permit further solicitation of
proxies. Any such adjournment will require the affirmative vote of a majority of
those shares represented at the annual meeting in person or by proxy. The
persons named as proxies will vote those proxies which they are entitled to vote
FOR any such proposal in favor of such an adjournment, and will vote those
proxies required to be voted AGAINST any such proposal against such adjournment.
A shareholder vote may be taken on one or more of the proposals in this proxy
statement prior to any such adjournment if sufficient votes have been received
and it is otherwise appropriate.

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. Abstentions and broker non-votes will be counted
as shares present for purposes of determining whether a quorum is present but
will not be voted for or against any adjournment or proposal. Accordingly,
abstentions and broker non-votes effectively will be a vote against adjournment
but will have no effect on Proposals 1 and 2, for which the required vote is a
plurality and majority, respectively, of the votes cast.

The individuals named as proxies on the enclosed proxy card will vote in
accordance with your direction as indicated thereon if your proxy card is
received properly executed by you or by your duly appointed agent or
attorney-in-fact. If you give no voting instructions, your shares will be voted
FOR the ten nominees for directors named herein and FOR the remaining proposals
described in this proxy statement. You may revoke any proxy card by giving
another proxy or by letter or telegram revoking the initial proxy. To be
effective, your revocation must be received by the Fund prior to the meeting and
must indicate your name and account number. In addition, if you attend the
meeting in person you may, if you wish, vote by ballot at the meeting, thereby
cancelling any proxy previously given.

As of the record date, July 21, 2000, the Fund had 37,922,480 shares of
common stock outstanding. The solicitation of proxies, the cost of which will be
borne by the Fund, will be made primarily by mail but also may include telephone
or oral communications by regular employees of Mitchell Hutchins Asset
Management Inc. ('Mitchell Hutchins') or PaineWebber Incorporated
('PaineWebber'), who will not receive any compensation therefor from the Fund.
Management does not know of any person who owns

<PAGE>
beneficially 5% or more of the shares of the Fund. Each full share of the Fund
outstanding is entitled to one vote and each fractional share of the Fund
outstanding is entitled to a proportionate share of one vote.

THE FUND'S ANNUAL REPORT CONTAINING FINANCIAL STATEMENTS FOR THE FISCAL YEAR
ENDED MAY 31, 2000, IS BEING MAILED TO SHAREHOLDERS CONCURRENTLY WITH THIS PROXY
STATEMENT.

Mitchell Hutchins serves as the Fund's investment adviser and administrator.

agreement are obtained, PW Group and UBS expect to complete the transaction in
the fourth quarter of 2000. UBS, with headquarters in Zurich, Switzerland, is an
internationally diversified organization with operations in many areas of the
financial services industry.

PROPOSAL 1. ELECTION OF DIRECTORS

Proposal 1 relates to the election of directors of the Fund. Management
proposes the election of the ten nominees named in the table below. Each
nominee, including those who are not 'interested persons' of the Fund as that
term is defined by the Investment Company Act of 1940 ('1940 Act') ('Independent
Directors'), has indicated his or her willingness to serve if elected. If
elected, each nominee will hold office until the next annual meeting of
shareholders or until his or her successor is elected and qualified. Unless you
give contrary instructions on the enclosed proxy card, your shares will be voted
FOR the election of the ten nominees. If any of the nominees should withdraw or
otherwise become unavailable for election, your shares will be voted FOR such
other nominee or nominees as management may recommend.

Each director, other than Mr. Storms, has served as a director from the
Fund's inception. Mr. Storms has served as a director of the Fund since May 13,
1999. Directors will be elected by the affirmative vote of the holders of a
plurality of the shares of the Fund, present in person or by proxy and entitled
to vote thereon, provided a quorum is present. If each of the ten nominees is
elected, they will constitute the entire board of directors of the Fund. The
current directors and executive officers as a group (19 persons) beneficially
owned 12,300 shares of the Fund on June 30, 2000.

* Mrs. Alexander, Mr. Bewkes, Ms. Farrell and Mr. Storms are 'interested
persons' of the Fund, as defined in the 1940 Act, by virtue of their
positions with Mitchell Hutchins, PaineWebber and/or PW Group.

** Unless otherwise stated, as of the date indicated, each director had sole
voting and investment power of shares owned.

The board of directors of the Fund met six times during the fiscal year
ended May 31, 2000. Other than Ms. Farrell, each director attended 75% or more
of the board meetings during the last fiscal year. The board has established an
Audit Committee that acts pursuant to a written charter and is responsible for
overseeing the Fund's accounting and financial reporting policies, practices and
internal controls. Each member of the Fund's Audit Committee is also a member of
a similar committee established by the boards of other investment companies for
which Mitchell Hutchins or PaineWebber serves as investment adviser. The Audit
Committee currently consists of Messrs. Armstrong, Burt, Feldberg, Gowen, Malek
and Schafer, all of whom have no relationship to the Fund that would interfere
with the exercise of their independence from management or the Fund and who
are independent as defined under listing standards of the New York Stock
Exchange. The Audit Committee met once during the fiscal year ended May 31,
2000 and each member attended that meeting.

The board does not have a standing nominating or compensation committee. The
Fund pays the Independent Directors $1,000 annually and up to $150 for each
board meeting and for each separate meeting of a board committee. The chairmen
of the audit and contract review committees of individual funds within the
PaineWebber fund complex each receive additional compensation aggregating
$15,000 annually from the relevant funds. Directors of the Fund who are
'interested persons' as defined in the 1940 Act receive no compensation from the
Fund. Directors are reimbursed for any expenses incurred in attending meetings.
Each director will be subject to mandatory retirement at the end of the year in
which he or she becomes 72 years old. The board has waived this requirement with
respect to Mr. Bewkes for the next year. The table below includes certain
information relating to the compensation of the Fund's directors.

has a bonus, pension, profit sharing or retirement plan.

PROPOSAL 2. RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

The Fund's financial statements for the fiscal year ended May 31, 2000, were
audited by Ernst & Young LLP ('Ernst & Young'), independent auditors. In
addition, Ernst & Young prepares the Fund's federal and state annual income tax
returns.

The board of directors of the Fund has selected Ernst & Young as the
independent auditors of the Fund for the fiscal year ending May 31, 2001,
subject to ratification by shareholders of the Fund at the annual meeting.
Ernst & Young has been the Fund's independent auditors since its inception in
June 1998. The ratification of Ernst & Young as independent auditors is to be
voted upon at the annual meeting, and it is intended that the persons named in
the accompanying proxy will vote FOR such ratification unless contrary
instructions are given. Ernst & Young has informed the Fund that it has no
material direct or indirect financial interest in the Fund. The affirmative vote
of the holders of a majority of the shares of the Fund cast at the annual
meeting is required for ratification, provided a quorum is present.

Representatives of Ernst & Young are not expected to be present at the
meeting but have been given the opportunity to make a statement if they so
desire and will be available should any matter arise requiring their presence.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE 'FOR' PROPOSAL 2.
