Dear Shareholder:
 
    Enclosed is a joint proxy statement ("proxy statement") asking you to vote
in favor of a proposal for the election of directors ("Board Members"), for your
Fund. Annual meetings are being held for the shareholders of Global High Income
Dollar Fund Inc., Investment Grade Municipal Income Fund Inc. and Strategic
Global Income Fund, Inc. Special meetings are being held for the shareholders of
Insured Municipal Income Fund Inc. and Managed High Yield Plus Fund Inc. In each
case, the meetings will be held on February 3, 2006 (the "Meetings") to consider
this proposal and to transact any other business that may properly come before
the Meetings. (The designation of a meeting as "annual" or "special" is linked
to when a Fund would normally hold a shareholder meeting during a year.
Shareholders are being asked to elect Board Members regardless of whether it is
being called an "annual" or a "special" meeting.)
 
    In the past, when we have solicited proxies for your Fund, we may have
enclosed a proxy statement directed solely to the shareholders of your Fund.
This time, however, shareholders of several Funds are being asked to approve the
same proposal with respect to the election of Board Members, and most of the
information that must be included in a proxy statement for your Fund needs to be
included in a proxy statement for the other Funds as well. Therefore, in order
to save your Fund money and to promote efficiency, one joint proxy statement has
been prepared for all of these Funds. This may also save time for investors
owning shares of more than one Fund.
 
    This proxy statement contains detailed information about the proposal, and
we recommend that you read it carefully. We have also attached a "Questions and
Answers" section that we hope will assist you in evaluating the proposal.

    Thank you for your attention to this matter.
 
                                 Sincerely,
 
                                 /s/ W. Douglas Beck
 
                                 W. Douglas Beck
                                 President of Each Fund
 

                                                           
Proxy cards for each of your Funds are enclosed along with
the proxy statement. Please vote your shares today by
signing and returning the enclosed proxy card(s) in the
postage prepaid envelope provided. The Board of each of your
Funds recommends that you vote "FOR" each proposal.


                             QUESTIONS AND ANSWERS
 

                                                 
Q:................................................  WHAT IS THE PURPOSE OF THIS PROXY SOLICITATION?
 
A:................................................  The purpose of this proxy solicitation is to ask
                                                    you to vote on the election of seven members of
                                                    the Board of Directors (the "Boards") of Global
                                                    High Income Dollar Fund Inc., Insured Municipal
                                                    Income Fund Inc., Investment Grade Municipal
                                                    Income Fund Inc., Managed High Yield Plus Fund
                                                    Inc. and Strategic Global Income Fund, Inc. (each,
                                                    a "Fund" and together the "Funds"), whose terms
                                                    will be effective beginning February 3, 2006 or,
                                                    in the event of postponement or an adjournment or
                                                    adjournments of the meetings of shareholders (the
                                                    "Meetings"), such later date as shareholder
                                                    approval is obtained.
 
I.................................................  BOARD PROPOSAL
 
Q:................................................  WHY AM I BEING ASKED TO VOTE FOR BOARD MEMBERS?
 
A:................................................  Over the course of the past several years, several
                                                    members of each Fund's Board (each, a "Board
                                                    Member") have ceased to serve as Board Members due
                                                    to retirement, resignation, or death. Each Board
                                                    currently has six Board Members, only four of whom
                                                    are standing for re-election. Each Board is
                                                    currently proposing for election seven nominees,
                                                    six of whom would be "Non-Interested Board
                                                    Members." ("Non-Interested Board Members" are
                                                    those Board Members who are not "interested
                                                    persons" of the Funds, as that term is defined in
                                                    the Investment Company Act of 1940, the primary
                                                    Federal statute regulating funds.)
 
                                                    Also, each Fund is listed on the New York Stock
                                                    Exchange, Inc. ("NYSE"). The NYSE requires each
                                                    Fund to hold an annual meeting each year for the
                                                    election of Board Members. For three of the Funds,
                                                    the Meeting will also serve as the "annual"
                                                    meeting, avoiding the expense of having two sets
                                                    of shareholder meetings in 2006. For the remaining
                                                    two Funds, the Meeting will be a "special"
                                                    meeting, and those Funds will need to hold
                                                    "annual" meetings at their usual time later this
                                                    year to vote on Board Members again because of the
                                                    timing of their fiscal year ends.

 


                                                 
Q:................................................  HOW WERE THE NOMINEES CHOSEN?
 
A:................................................  Each Fund's Nominating and Corporate Governance
                                                    Committee is responsible for reviewing and making
                                                    recommendations to the Board with respect to the
                                                    composition of the Board. Recognizing that two
                                                    current Board Members will retire from the Board
                                                    in 2006 pursuant to the Board's current mandatory
                                                    retirement age policy, the Nominating and
                                                    Corporate Governance Committee recommended the
                                                    election of three new Board Members. (Only one of
                                                    the current Board Members who will retire in 2006
                                                    is standing for re-election.) The Boards
                                                    considered the long-term welfare of the Funds and
                                                    determined that expanding the size of the Boards
                                                    would enhance the Boards' supervisory capabilities
                                                    over the Funds. Each Nominating and Corporate
                                                    Governance Committee then reviewed with the Board
                                                    the requisite skills and criteria for new Board
                                                    Members, and, in consultation with legal counsel
                                                    for the Non-Interested Board Members, conducted a
                                                    search for candidates for Board membership. Each
                                                    Nominating and Corporate Governance Committee
                                                    selected and recommended, and each Fund's Board
                                                    approved, the nominees to stand for election.
 
Q:................................................  IF THE BOARD PROPOSAL IS APPROVED BY SHAREHOLDERS,
                                                    HOW MANY BOARD MEMBERS WILL SIT ON THE BOARD?
 
A:................................................  If all nominees are elected, each Fund's Board
                                                    will consist initially of seven Board Members.
                                                    Four of these individuals currently serve as Board
                                                    Members; three will be new to each Fund's Board.
                                                    During 2006, one of the seven proposed Board
                                                    Members is expected to retire, reducing the number
                                                    of elected Board Members to six. (Two of the
                                                    current board members are not standing for
                                                    re-election.)
 
Q.................................................  WILL THE PROPOSALS BEING VOTED UPON INCREASE
                                                    ADVISORY FEES?
 
A.................................................  No. The advisory and administrative fees charged
                                                    to each Fund are not being voted upon.
                                                    Shareholders are being asked to elect Board
                                                    Members, not change advisory contracts or fees.

 

 

                                                 
Q.................................................  WILL THE PROPOSED CHANGES RESULT IN HIGHER FUND
                                                    EXPENSES?
A.................................................  Each Fund's expenses will increase by a relatively
                                                    immaterial amount. Each Non-Interested Board
                                                    Member receives compensation from the funds he or
                                                    she oversees in the form of an annual retainer and
                                                    a fee for each Board or Board Committee meeting
                                                    actually attended. The Chairman of the Board and
                                                    the Chairperson of each of the Audit Committee and
                                                    the Nominating and Corporate Governance Committee
                                                    each receive an additional annual retainer fee
                                                    associated with his or her position. These fees
                                                    are allocated among all UBS funds overseen by the
                                                    Board Member, including the Funds.
 
                                                    Each Fund's Board currently has four
                                                    Non-Interested Board Members. If all the nominees
                                                    are elected, each Fund's Board will initially
                                                    consist of seven Board Members, six of whom will
                                                    be Non-Interested Board Members. Accordingly, the
                                                    cost to each Fund of Non-Interested Board Member
                                                    compensation will increase if all nominees are
                                                    elected. The amount of this increase to an
                                                    individual Fund is expected to be relatively
                                                    immaterial.
II................................................  GENERAL QUESTIONS
Q:................................................  WHAT ARE THE BOARDS' RECOMMENDATIONS?
A:................................................  Each Fund's Board recommends that all shareholders
                                                    vote "FOR" the nominees for the Board.
Q:................................................  HOW CAN I VOTE?
A:................................................  You can vote:
                                                    -  By mail, with the enclosed proxy card; or
                                                    -  In person at the Meeting.
                                                    Whichever method you choose, please take the time
                                                    to read the proxy statement before you vote.
Q:................................................  I PLAN TO VOTE BY MAIL. HOW SHOULD I SIGN MY PROXY
                                                    CARD?
A:................................................  Please see the instructions at the end of the
                                                    Notice of the Annual and Special Meetings of
                                                    Shareholders, which is attached.
Q:................................................  WHY AM I RECEIVING PROXY INFORMATION FOR FUNDS
                                                    THAT I DO NOT OWN?
A:................................................  Since shareholders of each of these Funds are
                                                    being asked to approve a proposal for the election
                                                    of Board Members, most of the information that
                                                    must be included in a proxy statement for your
                                                    Fund needs to be included in a proxy statement for
                                                    the other Funds as well. Therefore, in order to
                                                    save money and to promote efficiency, one proxy
                                                    statement has been prepared for all of the Funds.
                                                    This may also save you time if you own shares of
                                                    more than one Fund.

 
     THE ATTACHED PROXY STATEMENT CONTAINS MORE DETAILED INFORMATION ABOUT
                    THE PROPOSAL. PLEASE READ IT CAREFULLY.

solicitation by their respective Board of Directors of proxies to be used at
annual (in the case of Investment Grade Municipal Income Fund Inc., Global High

    The principal business office and address of UBS Global AM is 51 West 52nd
Street, New York, New York 10019-6114. UBS Global AM is an indirect wholly-owned
subsidiary of UBS AG. UBS AG is an internationally diversified organization with
headquarters in Zurich and Basel, Switzerland. UBS AG operates in many areas of
the financial services industry. The principal business address of UBS AG is

                               VOTING INFORMATION
 
    Shareholders of record of a Fund at the close of business on November 23,
2005 (the "Record Date") are entitled to notice of, and to vote at, the Meeting
for that Fund. The number of Shares of each class of each Fund that were issued
and outstanding as of the Record Date is set forth in Exhibit B to this Proxy
Statement.
 
    QUORUM.  For each Fund, the presence, in person or by proxy, of a majority
of Shares of the Fund outstanding and entitled to vote on the Record Date will
constitute a quorum for the transaction of business at its Meeting.
 
    REQUIRED VOTE.  Board Members, including those who are not "interested
persons" of a Fund as that term is defined by the Investment Act of 1940, as
amended ("1940 Act") (each, an "Independent Board Member"), shall be elected by
the affirmative vote of the holders of a plurality of the shares of that Fund
cast in person or by proxy and entitled to vote thereon, provided a quorum is
present. Proxies cannot be voted for a greater number of persons than the number
of nominees named.
 
    In the event that a quorum is not present at the Meeting for a Fund
(including, with respect to Insured Municipal and Investment Grade Municipal, a
quorum of the Fund's auction preferred shares ("APS") with respect to the
election of the two Board Members to be elected solely by the APS), or if a
quorum is present at the Meeting but sufficient votes to approve a Proposal for
a Fund are not received, the persons named as proxies may propose one or more
adjournments of the Meeting for the affected Fund to permit further solicitation
of proxies. Any adjournment will require the affirmative vote of a majority of
those shares represented at the Meeting, whether in person or by proxy. The
persons named as proxies will vote those proxies which they are entitled to vote
"FOR" any proposal in favor of the adjournment, and will vote those proxies
marked "WITHHOLD" with respect to any 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.
 
    Brokers who hold shares in "street name" for customers have discretionary
authority to vote on "routine" proposals, such as the election of Board Members,
 
                                       3

when they have not received instructions from the beneficial owners of those
shares. 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 the broker does not have discretionary
voting authority. Abstentions and broker non-votes, if any, 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 will have no effect on a Proposal to elect
Board Members, for which the required vote is a plurality of the votes cast, but
effectively will be a vote against adjournment.
 
    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. With respect to each Fund other than Insured Municipal and Investment
Grade Municipal, if you give no voting instructions, your Shares will be voted
FOR the nominees named herein for the Board and, in the proxies' discretion,
either FOR or AGAINST any other business that may properly arise at the Meeting
(E.G., adjourning the Meeting). With respect to Insured Municipal and Investment
Grade Municipal: (1) with respect to the holders of the APS, if you give no
voting instructions, your shares will be voted FOR the seven nominees named
herein for the Board and, in the proxies' discretion, either FOR or AGAINST any
other business that may properly arise at the Meeting; and (2) with respect to
the holders of the Fund's common stock, if you give no voting instructions, your
shares will be voted FOR the five nominees named herein for the Board for which
the holders of the common stock are entitled to vote and, in the proxies'
discretion, either FOR or AGAINST any other business that may properly arise at
the Meeting. If any nominee for the Board should withdraw or otherwise become
unavailable for election, your Shares will be voted in favor of such other
nominee or nominees as the Board Members who are not Independent Board Members
may recommend.
 
    Any person giving a proxy has the power to revoke it at any time prior to
its exercise by executing a superseding proxy or by submitting a written notice
of revocation to the Fund's Secretary (the "Secretary") care of UBS Global AM at
51 West 52nd Street, New York, New York 10019-6114. To be effective, such
revocation must be received by the Secretary prior to the Meeting and must
indicate your name and account number. In addition, although mere attendance at
the Meeting will not revoke a proxy, a Shareholder present at the Meeting may
withdraw his or her proxy by voting in person.
 
    Management does not know of any person who owned 5% or more of the Shares of
any Fund as of November 23, 2005. To the knowledge of each Fund's Management,
the Executive Officers and the Board Members, as a group,
 
                                       4

owned less than 1% of the outstanding shares of each Fund as of November 23,
2005.
 
    COPIES OF EACH FUND'S MOST RECENT ANNUAL AND SEMIANNUAL REPORTS, INCLUDING
FINANCIAL STATEMENTS, HAVE PREVIOUSLY BEEN MAILED TO SHAREHOLDERS. SHAREHOLDERS
MAY REQUEST ADDITIONAL COPIES OF A FUND'S ANNUAL AND SEMIANNUAL REPORTS BY,
WITHOUT CHARGE, WRITING THE FUND C/O UBS GLOBAL AM AT 51 WEST 52ND STREET, NEW
YORK, NEW YORK 10019-6114, OR BY CALLING TOLL FREE 1-800-793-8637.
 
    With respect to each Fund other than Insured Municipal and Investment Grade
Municipal, each full Share outstanding is entitled to one vote and each
fractional Share outstanding (for those Funds that issue fractional Shares) is
entitled to a proportionate share of one vote with respect to each matter to be
voted upon by the Shareholders. With respect to Insured Municipal and Investment
Grade Municipal, and except as otherwise indicated herein, all of the
outstanding shares of a Fund's common stock and APS will vote together as a
single class. Each full share of the common stock or APS of Insured Municipal
and Investment Grade Municipal is entitled to one vote, and each fractional
share of each Fund's common stock or APS is entitled to a proportionate share of
one vote. However, as described below, the holders of the APS, voting as a
separate class, are entitled to elect two of their Fund's Board Members.
 
                  PROPOSALS FOR THE ELECTION OF BOARD MEMBERS
 
    DISCUSSION.  The Proposals relate to the election of Board Members for each
Fund. Each Fund proposes the election of the seven nominees named in the table
below to comprise its Board. If elected, the terms of the seven nominees will
begin effective February 3, 2006 or, in the event of a postponement or an
adjournment or adjournments of the Meetings, such later date as Shareholder
approval for a particular Fund is obtained (the "Effective Date"); until that
time, the current Board will continue its term. Each nominee has indicated a
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, or until he or she retires, resigns or is otherwise removed.
Mrs. Margo Alexander and Mr. William D. White, current members of each Board,
are not standing for re-election and will cease to be Board Members on the
Effective Date if the Proposal is approved by the Shareholders of a Fund. NOTE
THAT ONE OF THE NOMINEES, MR. DAVID J. BEAUBIEN, WHO IS CURRENTLY A MEMBER OF
EACH FUND'S BOARD, WILL REACH RETIREMENT AGE LATER IN 2006. ACCORDINGLY, IF THE
NOMINEES ARE ELECTED, ONLY SIX OF THE SEVEN NOMINEES MAY BE ON A BOARD BY THE
END OF 2006.
 
    Over the course of the past several years, several members of each Fund's
Board (each, a "Board Member") have ceased to serve as Board Members due to
retirement, resignation, or death. Each Board currently has six Board Members,
 
                                       5

only four of whom are standing for re-election. Each Board is seeking to expand
in size and is currently proposing for election seven nominees, six of whom
would be Non-Interested Board Members.
 
    Each Fund's Nominating and Corporate Governance Committee, which is
responsible for reviewing and making recommendations to the Board with respect
to the composition of the Board, recommended the election of new Board Members.
The Boards considered the long-term welfare of the Funds and determined that the
election of new Board Members would enhance the Boards' supervisory capabilities
over the Funds. Each Nominating and Corporate Governance Committee, in
consultation with legal counsel for the Non-Interested Board Members and
Professor Feldberg, then reviewed with the Board the requisite skills and
background possessed by the proposed new Board Members. In particular, the
Nominating and Corporate Governance Committees noted that the new nominees have
extensive investment industry and government experience, including accounting
and auditing responsibilities at a high level and investment management
oversight roles. Each Nominating and Corporate Governance Committee also noted
that the addition of the new Board Members, in light of the impending retirement
of incumbent Board Members, will help assure continuity of oversight of
management operations and compliance by each Fund's Board. Each Nominating and
Corporate Governance Committee selected and recommended, and each Fund's Board
approved, the nominees to stand for election.
 
    Each Fund, other than Insured Municipal and Investment Grade Municipal,
proposes the election by all of its shareholders of the seven nominees named in
the table below to comprise its Board. Insured Municipal and Investment Grade
Municipal each also propose the election of the seven nominees named in the
table below to comprise its Board. In the case of each of Insured Municipal and
Investment Grade Municipal, holders of the outstanding APS, voting as a separate
class, are entitled to elect two of the Fund's Board Members. Meyer Feldberg and
Richard R. Burt have been nominated as the Board Members that are to be elected
solely by holders of the APS of Insured Municipal and Investment Grade
Municipal. The other five Board Members will be elected by holders of the
outstanding common stock and APS, voting together as a single class. Richard Q.
Armstrong, David J. Beaubien, Alan S. Bernikow, Bernard H. Garil and Heather
Richardson Higgins have been nominated as the Board Members that are to be
elected by all common stock and APS holders of Insured Municipal and Investment
Grade Municipal. (The election of two Board Members solely by the holders of APS
is required by those Funds' Charters.)
 
    Mr. Alan S. Bernikow, Mr. Bernard H. Garil and Ms. Heather Richardson
Higgins were each nominated by each Fund's Nominating and Corporate Governance
Committee and then by the Board, along with the nominees who
 
                                       6

are existing Board Members, at a meeting held on July 20, 2005.
Messrs. Armstrong, Beaubien, Burt and Feldberg were last elected Board Members
at a Fund's 2005 Annual Meeting of Shareholders.
 
    Each Board believes that a Fund will benefit from the diversity and
experience of the nominees that would comprise the expanded Board. The nominees
have had distinguished careers in government, finance and other areas and will
bring a wide range of expertise to the Board. Six of the seven nominees, if
elected, would be Non-Interested Board Members. Non-Interested Board Members are
charged with special responsibilities to provide an independent check on
Management and to review advisory and certain other agreements between each Fund
and management. They also constitute the members of each Board's Audit
Committee. (The seventh nominee, Professor Meyer Feldberg, is treated as an
interested person of the Funds as defined in the 1940 Act because he is a senior
advisor to Morgan Stanley, a financial services firm with which the Funds may
conduct transactions.)
 
    The nominees for election as Board Members, their ages, a description of
their principal occupations and, for the current Board Members, the year each
was first elected or appointed as a Board Member are listed in the table below.
As of November 23, 2005, none of the nominees own Shares of the Funds named in
the Proxy Statement. A table indicating each nominee's ownership of Shares of
other funds in the UBS fund complex overseen or to be overseen by the nominee is
set forth in Exhibit D to this Proxy Statement.

the independent registered public accounting firm required by Independence
Standards Board Standard No. 1 and discussed the independent registered public
accounting firm's independence with them; and (d) based upon its review of the
above, recommended to the Board that the Fund's audited financial statements be
included in each Fund's annual report to Shareholders for the fiscal year.
 
    While each Fund's Audit Committee has the duties and responsibilities set
forth in its Audit Committee Charter and described above, each Fund's Audit
Committee is not responsible for planning or conducting the Fund's audit or for
determining whether the Fund's financial statements are complete and accurate
and are in accordance with generally accepted accounting principles. In
fulfilling their responsibilities under each Fund's Audit Committee Charter, it
is recognized (i) that the members of that Fund's Audit Committee are not
full-time employees of the Fund; (ii) it is not the duty or the responsibility
of the Audit Committee or its members to conduct "field work" or other types of
auditing or accounting reviews or procedures or to set auditor independence
standards; and (iii) each member of the Audit Committee shall be entitled to
rely on (a) the integrity of
 
                                       12

those persons within and outside the Fund from which it receives information;
(b) the accuracy of the financial and other information provided to the
Committee absent actual knowledge to the contrary (which shall be promptly
reported to the Board); and (c) statements made by the officers and employees of
the Fund, UBS Global AM or other third parties as to any information technology,
internal audit and other non-audit services provided by the independent auditors
to the Fund. The review of a Fund's financial statements by the Fund's Audit
Committee is not of the same quality as the audit performed by the independent
auditors.
 
    Each Fund's Audit Committee currently consists of Messrs. Armstrong,
Beaubien, Burt and White (a current Board Member who is not standing for re-
election), none of whom have any relationship to a Fund that may interfere with
the exercise of their independence from management or the Fund and each of whom
is independent as defined under listing standards of the New York Stock Exchange
("NYSE") applicable to closed-end Funds. Each member of a Fund's Audit Committee
is also a member of a similar committee established by the boards of certain
other investment companies for which UBS Global AM or an affiliate serves as
investment advisor, sub-advisor or manager. The Audit Committee met several
times during each Fund's last full fiscal year as set forth in Exhibit K, and
each member attended at least 75% of those meetings.
 
    Each Fund's Board has also established a Nominating and Corporate Governance
Committee that acts pursuant to a written charter ("Nominating and Corporate
Governance Committee Charter"). Each Fund's Nominating and Corporate Governance
Committee is responsible for, among other things: selecting, evaluating and
recommending to the Board candidates to be nominated as additional
Non-Interested Board Members; reviewing the composition of the Board and the
compensation arrangements for each of the Board Members; performing an annual
evaluation of the Board and its committees; reporting on such evaluation to the
Board; and performing such other corporate governance functions as the Board may
authorize. A copy of the Nominating and Corporate Governance Committee Charter
is attached as Exhibit F. Each Fund's Nominating and Corporate Governance
Committee currently consists of Messrs. Burt and White (a current Board Member
who is not standing for re-election), neither of whom is an "interested person"
for purposes of the 1940 Act, and both of whom are independent as defined under
listing standards of the NYSE applicable to closed-end funds. (The Nominating
and Corporate Governance Committee normally is comprised of at least three Board
Members; however, one member died in 2005, and Mr. White is not standing for
re-election. The Board anticipates that replacements will be appointed
subsequent to the elections of the nominees.) Each Nominating and Corporate
Governance Committee met several times during each Fund's last full fiscal year
 
                                       13

as set forth in Exhibit K, and each member attended at least 75% of those
meetings.
 
    In nominating candidates, each Nominating and Corporate Governance Committee
believes that no specific qualifications or disqualifications are controlling or
paramount, or that specific qualities or skills are necessary for each candidate
to possess. In identifying and evaluating nominees for Board membership, each
Nominating and Corporate Governance Committee takes into consideration such
factors as it deems appropriate. These factors may include: (i) whether or not
the person is an "interested person" as defined in the 1940 Act, meets the
applicable independence and experience requirements of the NYSE applicable to
closed-end funds and is otherwise qualified under applicable laws and
regulations to serve as a member of the Board; (ii) whether or not the person
has any relationships that might impair his or her independence, such as any
business, financial or family relationships with Fund management, the investment
advisor and/or sub-advisors of the Fund, other Fund service providers or their
affiliates; (iii) whether or not the person is willing to serve, and willing and
able to commit the time necessary for the performance of the duties of a Board
Member; (iv) the person's judgment, skill, diversity and experience with
investment companies and other organizations of comparable purpose, complexity
and size and subject to similar legal restrictions and oversight; (v) the
interplay of the candidate's experience with the experience of other Board
Members, and (vi) the extent to which the candidate would be a desirable
addition to the Board and any committees thereof.
 
    Each Nominating and Corporate Governance Committee will consider nominees
recommended by Shareholders if a vacancy occurs. In order to recommend a
nominee, a Shareholder should send a letter to the chairperson of each Fund's
Nominating and Corporate Governance Committee, Mr. Richard Burt, care of the
Secretary of the Fund at UBS Global Asset Management (US) Inc., 51 West 52nd
Street, New York, New York 10019-6114 and indicate on the envelope "Nominating
and Corporate Governance Committee." The Shareholder's letter should state the
nominee's name and should include the nominees RESUME or CURRICULUM VITAE, and
must be accompanied by a written consent of the individual to stand for election
if nominated by the Board and to serve if elected by Shareholders. No Fund's
Board has a standing compensation committee. Shareholders can send other
communications to a Board care of its chairman at the following address:
Mr. Richard Q. Armstrong--UBS Funds, c/o Wilkie Farr & Gallagher LLP, 787
Seventh Avenue, New York, NY 10019.
 
    Effective January 1, 2006, each Non-Interested Board Member will receive, in
the aggregate from the funds within the UBS fund complex he or she oversees
(including the Funds), an annual retainer of $95,000 and a $13,000 fee for each
regular joint Board meeting of the Boards of the funds (and each in-person
 
                                       14

special joint meeting of the Boards of the funds) actually attended. Non-
Interested Board Members who participate in previously scheduled in-person joint
meetings of the Boards of the funds by telephone to accommodate other business
obligations are paid $2,000 for such meetings. Non-Interested Board Members who
participate in previously scheduled in-person joint meetings of the Boards of
the funds by telephone because of illness or other unavoidable circumstances are
paid the full meeting fee. Effective January 1, 2006, each Non-Interested Board
Member will receive, from the relevant fund, $2,000 for each special in-person
meeting (not held as a joint meeting) of the Board of that fund actually
attended when a fund's Board must meet separately from the regulatory scheduled
joint Board meetings. Effective January 1, 2006, Non-Interested Board Members
who participate in scheduled telephone meetings of the Board(s) of one or more
funds are paid $1,000 for each such meeting actually attended.
 
    Effective January 1, 2006, the fund's Chairman will receive annually an
additional $50,000; the chairperson of the Audit Committee will receive annually
an additional $35,000; and the chairperson of the Nominating and Corporate
Governance Committee will receive annually an additional $25,000; provided that,
if a Board Member simultaneously holds more than one such position, he or she is
paid only the higher of the fees otherwise payable for these positions.
Effective January 1, 2006, Non-Interested Board Members who are also members of
the Audit Committee and/or Nominating and Corporate Governance Committee are
paid $2,000 for each meeting of such Committee actually attended, provided that
such meeting is not held in conjunction with a regularly scheduled Board
meeting. The foregoing fees will be allocated among all funds within the UBS
fund complex overseen by the Board Member (including the Funds) as follows:
(i) one-half of the expense will be allocated pro rata based on the funds'
relative net assets at the end of the calendar quarter preceding the date of
payment, and (ii) one-half of the expense will be allocated according to the
number of such funds (i.e., expenses divided by number of funds yields per-fund
allocation); provided, however, that where a special meeting is held with
respect to one or more funds (as opposed to joint meetings for all funds), then
only the relevant funds bear the related fees. All Board Members are reimbursed
for expenses incurred in attending meetings. Professor Feldberg, as an
interested Board Member, is compensated by management.
 
    Each Board Member who has attained the age of seventy-two (72) years will be
subject to retirement on the last day of the month on which he or she attains
such age.

     accordingly have not been compensated as Board Members for the Funds.
 
 **  Until March 1, 2005, Professor Feldberg was a Non-Interested Board Member
     and was compensated as such by the funds for which UBS Global AM or an
     affiliate served as investment advisor, sub-advisor or manager. Effective
     March 1, 2005, Professor Feldberg is an "interested person" of the funds by
     virtue of his position as senior advisor with Morgan Stanley. As such,
     Professor Feldberg is no longer compensated by the funds for which UBS
     Global AM serves as investment advisor, sub-advisor or manager. The
     compensation amounts listed in the Compensation Table for
     Professor Feldberg represent only those amounts paid by the funds.
 
  +  Only Non-Interested Board Members are compensated by the funds for which
     UBS Global AM or an affiliate serves as investment advisor, sub-advisor or
     manager; Board Members who are "interested persons," as defined in the 1940
     Act, do not receive compensation from the funds within the UBS fund
     complex.

INFORMATION CONCERNING THE FUNDS' INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
    Each Fund's financial statements for its last-completed fiscal year were
audited by Ernst & Young LLP ("Ernst & Young"), independent registered public
accounting firm. In addition, Ernst & Young prepares each Fund's federal and
state annual income tax returns and provides certain non-audit services. Each
Fund's Audit Committee has considered whether the provision of those non-audit
services is compatible with maintaining Ernst & Young's independence. Each Audit
Committee has selected Ernst & Young as the Fund's independent registered public
accounting firm and such selection has been ratified by each Fund's Board.
Ernst & Young's length of service as each Fund's independent registered public
accounting firm is set forth in Exhibit L. Ernst & Young has informed each Fund
that it has no material direct or indirect financial interest in the Fund.
 
    Representatives of Ernst & Young are not expected to be present at the
Meetings, 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.
 
AUDIT FEES.
 
    The aggregate fees billed by Ernst & Young for professional services
rendered to the Funds for the audit of each Fund's annual financial statements
for the last two fiscal years are set forth in Exhibit G. 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.
 
AUDIT-RELATED FEES.
 
    The aggregate audit-related fees billed by Ernst & Young for services
rendered to the Funds that are reasonably related to the performance of the
audits of the financial statements, but not reported as audit fees, during each
Fund's last two fiscal years are set forth in Exhibit H.
 
    Fees included in the audit-related category are those associated with
(1) the reading and providing of comments on each Fund's two most recent
semiannual financial statements, and (2) review of the consolidated reports to
certain UBS funds (including the Funds) on the profitability of management to
assist the Board Members in their advisory/administration contract reviews and
(3) with respect to Managed High Yield, performance of agreed-upon procedures
governing compliance with credit facility provisions for the Fund's two most
recent fiscal years. With respect to Insured Municipal and Investment Grade
Municipal, fees included in the audit-related fees categories also included
 
                                       17

(4) auction preferred shares testing for the Funds' two most recent fiscal year
ends.
 
    With respect to Rule 2-01(c)(7)(i)(c) of Regulation S-X, there were no
audit-related fees that were approved by the Audit Committee pursuant to the
DE MINIMIS exception for the Funds' two most recent fiscal years on behalf of
(i) the Funds' service providers that relate directly to the operations and
financial reporting of the Funds, or (ii) the Funds themselves. 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.
 
TAX FEES.
 
    The aggregate tax fees billed by Ernst & Young for services rendered to the
Funds for each of the last two fiscal years are set forth in Exhibit I. 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.
 
    With respect to Rule 2-01(c)(7)(i)(c) of Regulation S-X, there were no tax
fees that were approved by the Audit Committee pursuant to the DE MINIMIS
exception for the Funds' two most recent fiscal years on behalf of (i) the
Funds' service providers that relate directly to the operations and financial
reporting of the Funds, or (ii) the Funds themselves. 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.
 
ALL OTHER FEES.
 
    For the Funds' two most recent fiscal years, there were no fees billed by
Ernst & Young for other services provided to any Fund. 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 Funds.
 
    There were no fees billed by Ernst & Young for the most recent fiscal year
for professional services rendered for financial information systems design and
implementation services provided to the Funds, UBS Global AM and entities that
control, are controlled by or are under common control with UBS Global AM that
provide services to the Funds.
 
    With respect to Rule 2-01(c)(7)(i)(c) of Regulation S-X, there were no fees
within this category that were approved by the Audit Committee pursuant to the
DE MINIMIS exception for the Funds' two most recent fiscal years on behalf of
(i) the Funds' service providers that relate directly to the operations and
financial
 
                                       18

reporting of the Funds, or (ii) the Funds themselves. 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.
 
    Each Fund's Audit Committee Charter contains the Audit Committee's pre-
approval policies and procedures. Reproduced below is an excerpt from the Audit
Committee 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
 
------------------------
 
     (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 advisor 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 any permissible non-audit services
            are provided) by (a) the Fund, (b) its investment advisor and
            (c) any entity controlling, controlled by, or under common control
            with the investment advisor 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 are approved
            by the Committee (or its delegate(s)) prior to the completion of the
            audit.
 
                                       19

            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 its decision(s) to the
            Committee, at its next regularly scheduled meeting after the sub-
            committee's meeting. 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).
 
AGGREGATE NON-AUDIT FEES.
 
    The aggregate non-audit fees billed by Ernst & Young for services rendered
to the Funds for each of the last two fiscal years are set forth in Exhibit J.
No Fund's Audit Committee was required to consider whether the provision of non-
audit services that were rendered to the Fund's investment advisor (not
including any sub-advisor whose role is primarily portfolio management and is
subcontracted with or overseen by another investment advisor), and any entity
controlling, controlled by, or under common control with the investment advisor
that provides ongoing services to the Fund that were not pre-approved pursuant
to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X, was compatible with
maintaining Ernst & Young's independence.

                            AUDIT COMMITTEE CHARTER
                    AMENDED AND RESTATED AS OF MAY 12, 2004
 
ESTABLISHMENT AND PURPOSE
 
    This document serves as the Charter for the Audit Committee (the
"Committee") of the Board of each fund (the "Fund") advised by UBS Global Asset
Management (US) Inc. ("UBS Global") listed on Appendix A hereto (each such
Charter being a separate Charter). The primary purposes of the Committee are to
assist Board oversight of (1) the integrity of the Fund's financial statements,
(2) the Fund's compliance with legal and regulatory requirements, (3) the
independent auditors' qualifications and independence and (4) the performance of
the Fund's independent auditors.
 
    In performing its Board oversight assistance function, the Committee will,
among other things (a) oversee the scope of the Fund's audit, the quality and
objectivity of the Fund's financial statements, the Fund's accounting and
financial reporting policies and practices and its internal controls and, as
appropriate, the internal controls of certain service providers; (b) approve,
and recommend to the Board, for ratification, the selection, appointment,
retention or termination of the Fund's independent auditors, as well as
determining the compensation thereof; and (c) pre-approve all audit and
non-audit services provided to the Fund and certain other persons by such
independent auditors.
 
DUTIES AND RESPONSIBILITIES
 
    AUDIT OVERSIGHT
 
    The Fund's independent auditors are accountable to the Committee.
 
    The Committee shall:
 
    1.  Approve, and recommend to the Board for the Board's ratification, the
        selection, appointment, retention or termination of the Fund's
        independent auditors, or of any other public accounting firm engaged for
        the purpose of performing other audit, review or attest services for the
        Fund.
 
                                      E-1

    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 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
        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 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,
 
------------------------
 
(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 and any service
       providers controlling, controlled by or under common control with UBS
       Global 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

       including the delegation of some or all of the Committee's pre-approval
       responsibilities to other persons (other than UBS Global or the Fund's
       officers).
 
    3.  Discuss with the independent auditors any disclosed relationships or
        services that may diminish the objectivity and independence of the
        independent auditors; receive periodic reports from the independent
        auditors regarding the independent auditors' independence (including
        receiving the independent auditors' specific representations as to
        independence consistent with current statements of the Independence
        Standards Board); and discuss such reports with the independent
        auditors, and, if so determined by the Committee, recommend that the
        Board take appropriate action to ensure the independence of the
        independent auditors.
 
    4.  Review, in consultation with the independent auditors, the scope of the
        Fund's proposed audit each year, including the audit procedures to be
        utilized, and certain other matters in connection with the Fund's
        financial statements.
 
    5.  Inquire of UBS Global and the independent auditors as to the Fund's
        qualification under Subchapter M of the Internal Revenue Code and
        amounts distributed and reported to shareholders for Federal tax
        purposes.
 
    6.  [Closed-end Funds only] Review and discuss the Fund's audited annual
        financial statements and unaudited semiannual reports with UBS Global
        and, in the case of the audited financials, the independent auditors,
        including the Fund's disclosure of management's discussion of Fund
        performance.
 
    7.  Review with the independent auditors any problems or difficulties the
        auditors may have encountered during the conduct of the audit, relating
        to the conduct of the audit, including any matters required to be
        discussed pursuant to Statement of Auditing Standards No. 61, or any
        subsequent Statement, and management's response.
 
    8.  Ensure that the independent auditors submit on a periodic basis to the
        Committee a formal written statement delineating all relationships of
        the auditors consistent with Independence Standards Board Standard
        No. 1, or any subsequent Statement.
 
    9.  Review, in consultation, as appropriate, with the independent auditors
        and Fund service providers, matters relating to internal controls and
        disclosure controls and procedures at the Fund and at the Fund's service
        providers.
 
                                      E-3

10.  Request, receive and/or review from the independent auditors such other
     materials as deemed necessary or advisable by the Committee in the exercise
     of its duties under this charter; such materials may include, without
     limitation, any other material written communications bearing on the Fund's
     financial statements, or internal or disclosure controls, between the
     independent auditors and the Fund, UBS Global, the Fund's sub-adviser(s),
     if any, or other Fund service providers, such as any management letter or
     schedule of unadjusted differences, and any comment or "deficiency" letter
     received from a regulatory or self-regulatory organization addressed to the
     Fund, UBS Global or the Fund's sub-adviser(s), if any, that relates to
     services rendered to the Fund.
 
11.  Establish procedures for the receipt, retention and treatment of complaints
     that the Fund may receive regarding Fund accounting, internal accounting
     controls or auditing matters, including procedures (set forth on
     Appendix C hereto) for the confidential, anonymous submission by Fund
     officers or employees and the Fund's investment adviser (including
     sub-advisers, if any), administrator(s), principal underwriter or any other
     provider of accounting-related services for the Fund of concerns regarding
     questionable accounting or auditing matters related to the Fund.
 
12.  Request that the independent auditors report to the Committee on any
     unusual items or matters discovered during the course of any semi-annual or
     other reviews.
 
13.  [Closed-end Funds only] Consider and, if appropriate, recommend the
     publication of the Fund's annual audited financial statements in the Fund's
     annual report in advance of the printing and publication of the annual
     report, based on its review and discussions of such annual report with the
     independent auditors, the Fund's officers and UBS Global; and prepare the
     audit committee report required to be included in the Fund's proxy
     statement for its annual meeting of shareholders.
 
14.  [Closed-end Funds only] At least annually, obtain and review a report by
     the Fund's independent auditors describing (i) the independent auditors'
     internal quality-control procedures; (ii) any material issues raised by the
     most recent internal quality-control review, or peer review, of the
     independent auditors, or by any inquiry or investigation by governmental or
     professional authorities, within the preceding five years, respecting one
     or more independent audits carried out by the independent auditors, and any
     steps taken to deal with such issues; and (iii) (to assess the independent
     auditors' independence) all relationships between the independent auditor
     and the Fund.
 
                                      E-4

15.  [Closed-end Funds only] Discuss in general the Fund's periodic earnings
     releases, as well as any financial information and earnings guidance
     provided to analysts and rating agencies.
 
16.  [Closed-end Funds only] Discuss policies with respect to risk assessment
     and risk management.
 
17.  [Closed-end Funds only] Review hiring policies of UBS Global and the Fund,
     if any, for employees and former employees of the Fund's independent
     auditors.
 
18.  [Closed-end Funds only] Prepare an annual performance evaluation of the
     Committee for the Board's review.
 
19.  Review and reassess the adequacy of this Charter annually and recommend any
     proposed changes to the Board for approval.
 
    In performing its duties, the Committee shall be provided by UBS Global, the
Fund's sub-advisor(s), if any, or the Fund, as applicable, with such
information, data and services as the Committee shall request to discharge its
duties and responsibilities, shall consult as it deems appropriate with the
members of the Board, officers and employees of the Fund, UBS Global, the Fund's
sub-advisor(s), if any, the Fund's counsel and the Fund's other service
providers and, as it determines necessary to carry out its duties and at the
Fund's expense, may engage outside advisors and consultants. In carrying out its
functions, the Committee shall meet separately, periodically, with management
and with the Fund's independent auditors. The Fund shall provide appropriate
funding for the Committee to carry out its duties and responsibilities.
 
COMPOSITION
 
    The Committee shall have a minimum of three members and shall be composed of
a number of Board members, each of whom has been determined not to be an
"interested person," as that term is defined in Section 2(a)(19) of the
Investment Company Act of 1940, as amended ("1940 Act"), of the Fund (the
"Independent Board Members"), as the Board shall determine from time to time.
Each member of the Committee must also meet the independence and experience
requirements as set forth in Sections 303A.07(a) and 303.01(b)(2)(a) of the New
York Stock Exchange's Listed Company Manual, in each case as applicable to
closed-end Funds. The Committee shall elect a chairperson, who shall preside
over Committee meetings (the "Chairperson"). The Chairperson shall serve for a
term of three years, which term may be renewed from time to time.(2)
 
------------------------
 
2   In the case of a newly-organized UBS fund, the Chairperson(1)s term will be
    coterminous with those of the other UBS funds listed on Schedule A, even if
    such term is shorter than three years.
 
                                      E-5

    In addition, the Board shall use its best efforts to ensure that at least
one member of the Committee is an "audit committee financial expert," as
determined under the rules of the Securities and Exchange Commission.
Appendix B sets forth the audit committee financial expert requirements as of
the date of this amended and restated Charter. In the event that the Committee
does not have at least one such audit committee financial expert, the nominating
committee of the Board shall endeavor to identify and recommend to the Board a
candidate that meets such requirements or, in the event the Board does not, at
such time, have a nominating committee, the Board shall designate the
Independent Board Members as a committee to identify and recommend to the Board
a candidate that meets such requirements.
 
    For those Funds listed on the NYSE, no member of the Committee may serve on
the audit committees of more than three public companies, including all Funds
managed by UBS Global (deemed for these purposes to be a single public company),
unless the Board determines that such simultaneous service would not impair the
ability of such member to serve on the Committee effectively.
 
MEETINGS
 
    The Committee shall meet on a regular basis, but not less frequently than
twice a year. Special meetings may also be held upon reasonable notice to the
members of the Committee. An agenda shall be established for each meeting.
Additional meetings shall be called as circumstances require. The Committee may
request any officer or employee of the Fund, the Fund's counsel, UBS Global, the
Fund's sub-adviser(s), if any, the Fund's independent auditors or other
interested persons to attend a meeting of the Committee or to meet with any
members of, or consultants to, the Committee. The Committee will meet with the
Fund's independent auditors at least once a year outside the presence of the
Fund's officers and other parties. The Committee may, in its discretion, also
meet outside the presence of the Fund's officers and other parties at other
times. Meetings of the Committee may be held in person, by telephone or by other
appropriate means.
 
    One-third of the Committee's members shall constitute a quorum. At any
meeting of the Committee, the decision of a majority of the members present and
voting shall be determinative as to any matter submitted to a vote.
 
REPORTING
 
    The Chairperson shall report to the Board on the result of its deliberations
and make such recommendations as deemed appropriate.
 
                                      E-6

LIMITS ON ROLE OF COMMITTEE
 
    While the Committee has the duties and responsibilities set forth in this
Charter, the Committee is not responsible for planning or conducting the Fund's
audit or for determining whether the Fund's financial statements are complete
and accurate and are in accordance with generally accepted accounting
principles. In fulfilling their responsibilities hereunder, it is recognized
that the members of the Committee are not full-time employees of the Fund, it is
not the duty or the responsibility of the Committee or its members to conduct
"field work" or other types of auditing or accounting reviews or procedures or
to set auditor independence standards, and each member of the Committee shall be
entitled to rely on (a) the integrity of those persons within and outside the
Fund from which it receives information; (b) the accuracy of the financial and
other information provided to the Committee absent actual knowledge to the
contrary (which shall be promptly reported to the Board); and (c) statements
made by the officers and employees of the Fund, UBS Global or other third
parties as to any information technology, internal audit and other non-audit
services provided by the independent auditors to the Fund. The review of the
Fund's financial statements by the Committee is not of the same quality as the
audit performed by the independent auditors.
 
    In carrying out its responsibilities, the Committee's policies and
procedures shall be adapted, as appropriate, in order to best react to a
changing environment.
 
AMENDMENTS
 
    This Charter may be amended by a vote of a majority of the Board members.

        experience preparing, auditing, analyzing or evaluating financial
        statements that present a breadth and level of complexity of accounting

Appendix C
 
                        POLICIES OF THE AUDIT COMMITTEE
                  REGARDING CONCERNS OR COMPLAINTS RELATING TO
                  ACCOUNTING, INTERNAL ACCOUNTING CONTROLS OR
                   AUDITING MATTERS OR OTHER MATTERS RELATING
                         TO THE OPERATIONS OF THE FUND
 
INTRODUCTION
 
    The following policies are adopted by the Board of each fund ("Fund")
advised by UBS Global Asset Management (US) Inc. ("UBS Global AM") listed on
Appendix A to the Fund's Audit Committee Charter ("Charter").
 
    These policies shall constitute an amendment to, and a part of, the Charter
and shall be designated as Appendix C to the Charter. These policies constitute
the procedures to be established pursuant to Item 10 of "Duties and
Responsibilities--Audit Oversight" in the Charter; however, the Board has
decided to extend the benefit of these policies to all Funds, not just those
exchange-listed Funds that are required to establish such procedures pursuant to
Section 301 of the Sarbanes-Oxley Act and Rule 303A of the New York Stock
Exchange Inc. Listed Company Manual.
 
    These policies establish (1) procedures for the receipt, retention and
treatment of complaints received by the Fund (including Fund officers) regarding
accounting, internal accounting controls or auditing matters or other matters
relating to the operations of the Fund, (2) procedures for the confidential,
anonymous submission of concerns regarding questionable accounting or auditing
matters by employees of the investment adviser (and sub-advisor, if applicable),
administrator (and sub-administrator, if applicable), principal underwriter (if
any), or any other provider of accounting related services for the Fund (each a
"Service Provider") and (3) protections for such persons bringing complaints or
concerns to the attention of the Board's Audit Committee (the "Committee").
 
REPORTING
 
    It is expected that all board members and officers, as well as employees of
each Service Provider, will report promptly any concerns or complaints regarding
accounting, internal accounting controls or auditing matters or other matters
relating to the operations of the Fund. Employees of Service Providers
(including Fund officers) should first consider exhausting any internal
reporting mechanisms at their firm before directly contacting the Chairperson of
the Committee (or in the event of a potential conflict involving such person,
any
 
                                      E-10

other member of the Committee). If such a person does not receive a satisfactory
response within a reasonable period of time, or if he or she believes that
utilizing internal reporting mechanisms would be futile or otherwise
undesirable, he or she should (1) in the case of Service Providers under the
supervision of UBS Global AM (e.g., State Street Bank and Trust or PFPC, Inc.),
contact UBS Global AM via the "ethics hotline" and/or mailbox referenced below
(unless such person believes that using such "ethics hotline" and/or mailbox
would be futile or otherwise undesirable, in which case he or she should report
concerns as directed in the remainder of this sentence); or (2) in the case of
all other persons, contact the Chairperson of the Committee directly (or in the
event of a potential conflict involving such person, any other member of the
Committee).
 
    The Committee requests that each Service Provider promptly inform it of
complaints or concerns received from its employees pursuant to these or any
similar policies it may have if such complaints or concerns are reasonably
believed to relate to accounting, internal accounting controls or auditing
matters or other matters relating to the operations of the Fund.
 
    The Committee directs UBS Global AM to communicate these policies to its
primary contact(s) at each other Service Provider. Each Service Provider,
including UBS Global AM, shall be directed to make these methods by which
complaints or concerns can be communicated known to its employees who are
primarily involved in accounting, internal accounting controls or auditing
matters or other matters relating to the operations of the Fund that could
reasonably be expected to impact the Fund. If any Service Provider refuses such
request, UBS Global AM shall notify the Committee of the Service Provider's
reasons for non-cooperation, and the Committee shall recommend to the Board such
actions as it believes appropriate.
 
NON RETALIATION
 
    The Fund prohibits any form of retaliation being taken against any board
member or officer, and shall request that each Service Provider not take any
form of retaliation against its employees, as a result of such person lawfully
engaging in any of the following "Covered Activities":
 
    1.  reporting concerns or complaints regarding accounting, internal
        accounting controls or auditing matters or other matters relating to the
        operations of the Fund; or
 
    2.  assisting in an internal or external investigation conducted by the Fund
        or a Service Provider regarding such concerns or complaints; or
 
    3.  filing, testifying, participating or otherwise assisting in a criminal
        or regulatory proceeding relating to the Fund or a Service Provider.
 
                                      E-11

    To the extent possible, the Board shall seek assurances from Service
Providers that they shall not discharge, demote, suspend, threaten, harass, or
in any other manner discriminate against an employee in the terms and conditions
of his or her employment because such employee has made a report of a concern or
complaint or engaged in any other Covered Activities under these policies. In
addition, the Board shall seek assurances from Service Providers that they shall
not knowingly, with the intent to retaliate, take any action harmful to any
employee, including interference with the lawful employment or livelihood of any
person, for providing to a law enforcement officer any truthful information
relating to the commission or possible commission of any crime.
 
CONFIDENTIALITY
 
    Reasonable efforts will be made to keep a reporting person's identity
confidential. In certain circumstances, however, it may be possible that in the
course of the investigation, facts must be disclosed that would require the
identity of the reporting person to be disclosed. Accordingly, in such
circumstances, it is not possible to give a blanket guarantee of
confidentiality. However, the Committee shall take all reasonable steps (and ask
its Service Providers to make reasonable efforts) to attempt to safeguard the
submission of information on a confidential basis.
 
    A Fund Person or Service Provider employee may submit information
anonymously to the Committee through a letter addressed directly to the Chairman
of the Committee (or in the event of a potential conflict involving such person,
to any other member of the Committee at the Chairman's (or other Committee
member's) address as specified in the Fund's Annual Report to Shareholders. The
Committee recognizes that certain Service Providers have established their own
procedures for the confidential, anonymous receipt of concerns or complaints and
requests that Service Providers promptly report to the Committee any concerns or
complaints relating to the matters discussed herein.
 
ETHICS HOTLINE & MAILBOX
 
    Where circumstances preclude the use of conventional channels, UBS Global AM
has established an ethics hotline and a physical mailbox to facilitate the
confidential, anonymous submission of concerns regarding potential legal/
regulatory violations and questionable accounting or auditing matters or other
matters relating to the operations of a Fund or other ethical dilemmas. The
hotline is available for leaving a voicemail message 24-hours a day, seven days
a week. In order to protect confidentiality, only the UBS Global AM General
Counsel and Chief Compliance Officer will be authorized to retrieve messages.
Please utilize the hotline and the mailbox only for this stated purpose. The
ethics hotline number is 866-237 1851. Written submissions should be addressed
 
                                      E-12

to: UBS Global Asset Management (US) Inc., Attn: ETHICS, 51 West 52nd Street,
New York, NY 10019-6114.
 
BREACH OF THIS POLICY
 
    Retaliatory conduct which amounts to a breach of this policy could result in
criminal or regulatory sanctions or civil liability or have an adverse effect on
the Fund's or a Service Provider's reputation. As a result, a breach of this
policy may constitute gross misconduct and may result in disciplinary action up
to and including dismissal from service as a board member or officer, or with
respect to a Service Provider, the Board's decision to terminate any Fund
contracts or other relationships with the Service Provider.
 
RETENTION AND TREATMENT OF INFORMATION REGARDING CONCERNS AND COMPLAINTS
 
    The Committee minutes shall reflect the receipt, retention and treatment of
information received pursuant to this policy. The Committee shall have the power
to obtain the resources it deems necessary and appropriate to investigate any
information regarding such concerns or complaints, including obtaining the
assistance of special counsel, auditors or other advisors or consultants to
assist it in carrying out its responsibilities.
 
                                                                      (May 2004)

             NOMINATING AND CORPORATE GOVERNANCE COMMITTEE CHARTER
 
                  AMENDED AND RESTATED AS OF NOVEMBER 10, 2004
 
ESTABLISHMENT AND PURPOSE
 
This document serves as the Charter for the Nominating and Corporate Governance
Committee (the "Committee") of the Board of each fund (the "Fund") advised by
UBS Global Asset Management (US) Inc. ("UBS Global") listed on Appendix A hereto
(each such Charter being a separate Charter). The primary purposes of the
Committee are to (a) identify individuals qualified to serve as members of the
Board of Directors/Trustees (the "Board") of each Fund; (b) make recommendations
to the Board on the composition of the Board; (c) recommend committee
assignments and responsibilities to the Board; (d) make recommendations to the
Board regarding corporate governance matters and responsibilities; and
(e) periodically assess the functioning of the Board and its committees
(including the Committee).
 
COMPOSITION
 
    1.  The Committee shall consist of three or more Board members who are not
        "interested persons" of the Fund, as that term is defined in
        Section 2(a)(19) of the Investment Company Act of 1940, as amended
        ("1940 Act"), of the Fund (the "Independent Board Members"). Each member
        of the Committee must also meet the independence and experience
        requirements applicable to closed-end funds as they may be adopted and
        modified from time to time by the New York Stock Exchange (the "NYSE").
        Each Committee member shall serve until a successor to such member is
        duly elected or qualified or until such member's resignation or removal
        from the Board or the Committee.
 
    2.  The Committee shall elect a chairperson (the "Chairperson") of the
        Committee, who shall preside over Committee meetings.
 
    3.  The compensation of the Chairperson and the Committee members shall be
        as determined by the Board.
 
NOMINATION AND APPOINTMENT POLICY
 
    1.  The Committee believes that it is in the best interests of the Fund and
        its shareholders to obtain highly-qualified candidates to serve as
        members of the Board.
 
    2.  In nominating candidates, the Committee believes that no specific
        qualifications or disqualifications are controlling or paramount, or
        that
 
                                      F-1

        specific qualities or skills are necessary for each candidate to
        possess. The Committee shall take into consideration such factors as it
        deems appropriate. These factors may include:
 
        -   whether or not the person is an "interested person" as defined in
            the 1940 Act, meets the independence and experience requirements of
            the NYSE cited above and is otherwise qualified under applicable
            laws and regulations to serve as a member of the Board;
 
        -   whether or not the person has any relationships that might impair
            his or her independence, such as any business, financial or family
            relationships with Fund management, the investment advisor and/or
            sub-advisors of the Fund, Fund service providers or their
            affiliates;
 
        -   whether or not the person is willing to serve, and willing and able
            to commit the time necessary for the performance of the duties of a
            Board member;
 
        -   the person's judgment, skill, diversity and experience with
            investment companies and other organizations of comparable purpose,
            complexity and size and subject to similar legal restrictions and
            oversight,
 
        -   the interplay of the candidate's experience with the experience of
            other Board members; and
 
        -   the extent to which the candidate would be a desirable addition to
            the Board and any committees thereof.
 
    3.  While the Committee is solely responsible for the selection and
        recommendation to the Board of Board candidates, the Committee will
        consider nominees recommended by Fund shareholders if a vacancy occurs
        among those Board members who are Independent Board Members. Such
        recommendations shall be directed to the Secretary of the Fund at such
        address as is set forth in the Fund's disclosure documents. The
        shareholder's letter should state the nominee's name and should include
        the nominee's resume or curriculum vitae, and must be accompanied by a
        written consent of the individual to stand for election if nominated for
        the Board and to serve if elected by shareholders. The Committee may
        also seek such additional information about the nominee as it considers
        appropriate, including information relating to such nominee that is
        required to be disclosed in solicitations or proxies for the election of
        Board members.
 
                                      F-2

    4.  The Committee may from time to time establish specific requirements
        and/or additional factors to be considered for Board candidates as it
        deems necessary or appropriate.
