                                PROXY STATEMENT
         ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON NOVEMBER 16, 1995
                             ---------------------
 
     This Proxy statement is furnished to the shareholders of PaineWebber 
Premier High Income Trust Inc. (doing business as Managed High Yield Fund)
('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
November 16, 1995, or any adjournment or adjournments thereof.
 
     A majority of the shares outstanding on September 27, 1995, 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. Accordingly, abstentions and
broker non-votes effectively will be a vote against adjournment or against any
proposal where the required vote is a percentage of the shares present.
Abstentions and broker non-votes will not be counted, however, as votes cast for
purposes of determining whether sufficient votes have been received to approve a
proposal.
 
     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
in favor of the five nominees for directors named herein and in favor of the
remaining proposals described in this proxy statement. The proxy card may be
revoked by giving another proxy or by letter or telegram revoking your proxy. To
be effective, such revocation must be received by the Fund prior to the annual 
meeting and must indicate your name and account number. In addition, if you 
attend the annual meeting in person you may, if you wish, vote by ballot at 
the annual meeting, thereby cancelling any proxy previously given.

 
     As of the record date, September 27, 1995, the Fund had 6,031,667 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 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 for such purposes. This proxy statement will
first be mailed to shareholders on or about September 29, 1995. The Fund's
annual


report containing financial statements for the fiscal year ended July 31, 1995
is being mailed to shareholders concurrently with this proxy statement.
 
     Mitchell Hutchins serves as the Fund's investment adviser and
administrator. Mitchell Hutchins is a wholly owned subsidiary of PaineWebber,
which is a wholly owned subsidiary of Paine  Webber Group Inc. ('PW Group'), a
publicly held financial services holding comp any. PaineWebber acts as a dealer
and secondary market-maker in connection with over-the-counter secondary market
sales of the Fund's shares. The principal business address of each of Mitchell
Hutchins, PaineWebber and PW Group is 1285 Avenue of the Americas, New York, New
York 10019.
 
                                 PROPOSAL NO. 1
                     AMENDMENT OF ARTICLES OF INCORPORATION
 
     Proposal 1 relates to the amendment of the Fund's Articles of 
Incorporation to change the name of the Fund from 'PaineWebber Premier High
Income Trust Inc.' to 'Managed High Yield Fund Inc.'
 
     On June 2, 1995, the Fund's board of directors, acting upon the
recommendation of Mitchell Hutchins, determined to recommend this name change to
the Fund's shareholders. At the same time, the board of directors approved the
Fund's use of 'Managed High Yield Fund' as a trade name pending a shareholders'
meeting at which a vote on a formal name change could be taken. The Fund has
been doing business as 'Managed High Yield Fund' since necessary approvals
relating to the Fund's listing under that name on the New York Stock Exchange,
Inc. were obtained in August 1995.
 
     The proposed name change, like the use of 'Managed High Yield Fund' as a
trade name, is intended to facilitate broadened secondary market trading of the
Fund's shares within the general brokerage community. Mitchell Hutchins has
advised the board of directors that recent discounts from net asset value in
secondary market trading of Fund shares may be due in part to a reluctance by
many brokerage firms to actively follow and trade closed-end investment
companies that are closely associated with a particular retail brokerage firm.
Mitchell Hutchins and the board of directors believe that the proposed name
change will remove that obstacle to more active trading, while accurately
describing the Fund's investment objective and policies and, therefore, should
benefit shareholders by helping to remove market discounts. Approval of this

proposal requires the affirmative vote of a majority of the votes entitled to be
cast thereon.
 
       THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE 'FOR' PROPOSAL 1.
 
                       PROPOSAL 2. ELECTION OF DIRECTORS
 
     Proposal 2 relates to the election of directors of the Fund. Management
proposes the election of the five nominees named in the table below as directors
of the Fund. At a meeting of the board held on June 2, 1995, the board
determined to expand the Fund's board of directors from three to five and
determined to recommend Messrs. Armstrong and Burt as nominees to serve as
directors, subject to shareholder approval. 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 willingness to serve if elected. If elected, each nominee will
hold office until the next annual meeting of shareholders or until his successor
is elected and qualified. Unless you give contrary instructions on the enclosed
proxy card, your shares will be voted in favor of the election of the five
nominees. If any of the nominees should withdraw or otherwise become unavailable
for election, your shares will be voted in favor of such other nominee or
nominees as management may recommend.
 
                                       2

     Messrs. Torell and White have served as directors of the Fund since its
inception in 1993. Mr. Bewkes served as a director from the Fund's inception
until his resignation from the board on December 10, 1993; he was reappointed to
the board on December 27, 1993. Messrs. Richard Q. Armstrong and Richard R. Burt
have not previously served as directors of the Fund. Directors shall be elected
by the vote of the holders of a majority of the shares of the Fund present in
person or by proxy and entitled to vote thereon. If each of the five nominees is
elected, they will constitute the entire board of directors of the Fund. All
directors and executive officers as a group (16 persons) beneficially owned 212
shares of the Fund, including shares shown in the table below, on August 31,
1995, representing less than 1% of shares of the Fund outstanding on that date.

and recommend approval or disapproval of audit and non-audit services and the
fees charged for such services; (c) to evaluate the independence of the
independent auditors and to recommend whether to retain such independent
auditors for the next fiscal year; and (d) to report to the board and make such
recommendations as it deems necessary. The Audit Committee met twice during the
