1999 ANNUAL MEETING OF STOCKHOLDERS

December 15, 1999

INTRODUCTION

This Proxy Statement is furnished in connection with the solicitation of
proxies on behalf of the Boards of Directors of the above-listed Funds (each a
"Fund" and, collectively, the "Funds") to be voted at the 1999 Annual Meeting of
Stockholders of each Fund (each a "Meeting" and collectively, the "Meetings"),
to be held at the offices of Merrill Lynch Asset Management, L.P. ("MLAM"), 800
Scudders Mill Road, Plainsboro, New Jersey, on Wednesday, December 15, 1999 at
the time specified in Exhibit A hereto. The approximate mailing date of this
Proxy Statement is November 4, 1999.

All properly executed proxies received prior to the Meeting will be voted
at the Meeting in accordance with the instructions marked thereon or otherwise
as provided therein. Unless instructions to the contrary are marked, proxies
will be voted for the election of the Board of Directors of each Fund to serve
for the ensuing year and for the ratification of the selection of independent
auditors to serve for each Fund's current fiscal year. Any proxy may be revoked
at any time prior to the exercise thereof by giving written notice to the
Secretary of the applicable Fund at that Fund's address indicated above or by
voting in person at the Meeting.

The Board of Directors of each Fund has fixed the close of business on
October 20, 1999 as the record date (the "Record Date") for the determination of
stockholders entitled to notice of and to vote at the Meetings and at any
adjournment thereof. Stockholders on the Record Date will be entitled to one
vote for each share held, with no shares having cumulative voting rights. As of
the Record Date, each Fund had outstanding the number of shares of common stock
("Shares") and shares of auction market preferred stock ("AMPS") indicated in
Exhibit A. To the knowledge of each Fund, as of the Record Date, no person is
the beneficial owner of more than five percent of its outstanding Shares or AMPS
at such date.

The Board of Directors of each Fund knows of no business other than that
mentioned in Items 1 and 2 of the Notice of Meeting that will be presented for
consideration at the Meeting. If any other matter is properly presented, it is
the intention of the persons named in the enclosed proxy to vote in accordance
with their best judgment.

ITEM 1. ELECTION OF DIRECTORS

At the Meetings, the Board of Directors of each Fund will be elected to
serve until the next Annual Meeting of Stockholders for such Fund and until
their successors are elected and qualified. It is intended that all properly
executed proxies will be voted (unless such authority has been withheld in the
proxy) as follows:

(1) All such proxies of the holders of shares of AMPS, voting
separately as a class, in favor of the two (2) persons designated as
Directors to be elected by holders of AMPS; and

(2) All such proxies of the holders of shares of Common Stock and
AMPS, voting together as a single class, will be voted in favor of the five
(5) persons designated as Directors to be elected by holders of Common
Stock and AMPS.

The Board of Directors of each Fund knows of no reason why any of
these nominees will be unable to serve, but in the event of any such
unavailability, the proxies received will be voted for such substitute
nominee or nominees as the Board of Directors may recommend.

Certain information concerning the nominees, including their designated
classes, is set forth below. Additional information concerning the nominees is
set forth in Exhibit A.

- -----------
(1) Each of the nominees is a director, trustee or member of an advisory board
of certain other investment companies for which FAM or MLAM acts as
investment adviser. See "Information pertaining to Officers and
Directors" in Exhibit A.

(2) Member of the Audit Committee of each Board.

* Interested person, as defined in the Investment Company Act of 1940, as
amended (the "Investment Company Act"), of the Fund.

Committee and Board of Directors' Meetings. The Board of Directors of each
Fund has a standing Audit Committee, which consists of the Directors who are not
"interested persons" of that Fund within the meaning of the Investment Company
Act. The principal purpose of the Audit Committee is to review the scope of the
annual audit conducted by each Fund's independent auditors and the evaluation by
such auditors of the accounting procedures followed by the Fund. The
non-interested Directors have retained independent legal counsel to assist them
in connection with these duties. No Fund's Board of Directors has a nominating
committee.

During each Fund's last fiscal year, each of the Board of Directors then
in office attended at least 75% of the aggregate of the total number of meetings
of the Board of Directors and, if a member, of the total number of meetings of
the Audit Committee held during such period.

Compliance with Section 16(a) of the Securities Exchange Act of 1934.
Section 16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), requires the officers and directors of each Fund and persons who own more
than ten percent of a registered class of each Fund's equity securities, to file
reports of ownership and changes in ownership on Forms 3, 4 and 5 with the
Securities and Exchange Commission ("SEC") and the New York Stock Exchange.
Officers, directors and greater than ten percent stockholders are required by
SEC regulations to furnish the Fund with copies of all Forms 3, 4 and 5 they
file.

Based solely on each Fund's review of the copies of such forms, and
amendments thereto, furnished to it during or with respect to its most recent
fiscal year, and written representations from certain reporting persons that
they were not required to file Form 5 with respect to the most recent fiscal
year, each Fund believes that, all of its officers, directors, greater than ten
percent beneficial owners and other persons subject to Section 16 of the
Exchange Act due to the requirements of Section 30 of the Investment Company
Act, (i.e., any advisory board member, investment adviser or affiliated person
of the Fund's investment adviser), have complied with all filing requirements
applicable to them with respect to transactions during the Fund's most recent
fiscal year except that Robert A. Didella inadvertently failed to make a timely
Form 4 filing disclosing his purchase of shares of MuniHoldings Fund, Inc. and
failed to file a timely Form 5 disclosing his annual total purchases and shares
of MuniHoldings Fund II, Inc. These oversights were corrected by subsequent
filings.

Interested Persons. Each Fund considers Mr. Zeikel and Mr. Glenn to be
"interested persons" of the Fund within the meaning of Section 2(a)(19) of the
Investment Company Act due to the positions each holds or has held with FAM and
its affiliates and/or due to their ownership of securities issued by ML & Co.
Mr. Glenn is the President of each Fund.

Compensation of Directors. FAM, the investment adviser of each Fund, pays
all compensation of all officers and all Directors of the Funds who are
affiliated with ML & Co. or its subsidiaries. Each Fund pays each Director not
affiliated with FAM (each a "non-interested Director") a fee of $1,000 per year
plus $200 per meeting attended, together with such Director's actual
out-of-pocket expenses relating to attendance at meetings. Each Fund also pays
each member of its Audit Committee, which consists of all the non-interested
Directors, an annual fee of 800 per year together with such Director's
out-of-pocket expenses relating to attendance at meetings. The Chairman of the
Audit Committee receives an additional fee of $1,000. Information with respect
to fees and expenses paid to the Directors for each Fund's most recently
completed fiscal year is set forth in Exhibit A.

Officers of the Fund. Information regarding the officers of each Fund is
set forth in Exhibit A. Officers of a Fund are elected and appointed by the
Board of Directors and hold office until they resign, are removed or are
otherwise disqualified to serve.

Stock Ownership. At the Record Date, the Directors and officers of each
Fund as a group (14 persons) owned an aggregate of less than 1% of the Common
Stock of each Fund outstanding at such date and owned none of the AMPS
outstanding at such date. At such date, Mr. Zeikel, a Director of each Fund, and
Mr. Glenn, a Director and Officer of each Fund, and the other officers of each
Fund owned an aggregate of less than 1% of the outstanding shares of common
stock of ML & Co.

ITEM 2. SELECTION OF INDEPENDENT AUDITORS

The Board of Directors of each Fund, including a majority of the Directors
who are not interested persons of the Fund, have selected independent auditors
to examine the financial statements of the Fund for the current

fiscal year. No Fund knows of any direct or indirect financial interest of such
firm in that Fund. Such appointment is subject to ratification or rejection by
the stockholders of each Fund. Unless a contrary specification is made, the
accompanying proxy will be voted in favor of ratifying the selection of such
auditors.

Ernst & Young, LLP has been selected by each Fund's Board to act as
independent auditors. E&Y also acts as independent auditors for other investment
companies for which FAM acts as investment adviser. The fees received by E&Y
from these other entities are substantially greater, in the aggregate, than the
fees received by it from the Fund. The Board of Directors of each of the Funds
considered the fact that E&Y has been retained as the independent auditors for
such other entities in its evaluation of the independence of E&Y with respect to
the applicable Fund.

Representatives of E&Y are expected to be present at the meeting and will
have the opportunity to make a statement if they so desire and to respond to
questions from stockholders.

ADDITIONAL INFORMATION

The expenses of preparation, printing and mailing of the enclosed forms of
proxy and accompanying Notice and Proxy Statement will be borne by the Funds in
proportion to their relative net assets. The Funds will reimburse banks, brokers
and others for their reasonable expenses in forwarding proxy solicitation
material to the beneficial owners of the shares of the Funds.

In order to obtain the necessary quorum at each Meeting (i.e., a majority
of the shares of each class of each Fund's securities entitled to vote at each
Meeting, present in person or by proxy), supplementary solicitation may be made
by mail, telephone, telegraph or personal interview by officers of the Fund.

All shares represented by properly executed proxies, unless such proxies
have previously been revoked, will be voted at the Meetings in accordance with
the directions on the proxies; if no direction is indicated, the shares will be
voted "FOR" the Director nominees and "FOR" the ratification of E&Y as
independent auditors.

With respect to Item 1, "Election of Directors," holders of AMPS, voting
separately as a class, are entitled to elect the two Directors designated above
and holders of Common Stock and AMPS, voting together as a single class, are
entitled to elect the remaining Directors. Assuming a quorum is present, (i)
election of the two Directors to be elected by the holders of AMPS, voting
separately as a class, will require a plurality of the votes cast by the holders
of AMPS, represented at each Meeting and entitled to vote: (ii) election of the
remaining Directors will require a plurality of the votes cast by the holders of
Common Stock and the AMPS represented at each Meeting and entitled to vote,
voting together as a single class.

With respect to Item 2. "Ratification of the Selection of Independent
Auditors," assuming a quorum is present, approval will require the affirmative
vote of a majority of the votes cast by the holders of shares of Common Stock
and the AMPS represented present in person or by proxy at each Meeting and
entitled to vote, voting together as a single class.

Broker-dealer firms, including Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("MLPF&S'"), holding shares of each Fund in "street name" for the
benefit of their customers and clients, will request the instructions of such
customers and clients on how to vote their shares on each Item before the
Meeting. The Funds understand that, under the rules of the New York Stock
Exchange, such broker-dealer firms may, without instructions from their
customers and clients, grant authority to the proxies designated to vote on the
election

of Directors (Item 1) and ratification of the selection of independent auditors
(Item 2) if no instructions have been received prior to the date specified in
the broker-dealer firm's request for voting instructions. The Fund will include
shares held of record by broker-dealers as to which such authority has been
granted in its tabulation of the total number of votes present for purposes of
determining whether the necessary quorum of stockholders exists. Proxies that
are returned but that are marked "abstain" or on which a broker-dealer has
declined to vote on any proposal ("broker non-votes") will be counted as present
for the purposes of a quorum. MLPF&S has advised the Fund that it intends to
vote shares held in its name for which no instructions have been received except
as limited by agreement or applicable law, on Items 1 and 2 in the same
proportion as the votes received from beneficial owners of those shares for
which instructions have been received, whether or not held in nominee name.
Abstentions and broker non-votes will not be counted as votes cast. Abstentions
and broker non-votes, therefore, will not have an effect on the vote on Item 1
or Item 2.

Address of Investment Adviser

The principal office of FAM is located at 800 Scudders Mill Road,
Plainsboro, New Jersey 08536.

Annual Report Delivery

Each Fund will furnish, without charge, a copy of its annual report for
the Fund's last fiscal year and a copy of its most recent Semi-Annual report to
any stockholder upon request. Such requests should be directed to the applicable
Fund, P.O. Box 9011, Princeton, New Jersey 08543-9011, Attention: William E.
Zitelli, Jr., Secretary, or to 1-800-456-4587 ext. 123.

Stockholder Proposals

It is currently intended that the 2000 Annual Meeting of Stockholders of
the Fund will be held in December 2000. If a stockholder intends to present a
proposal at the 2000 Annual Meeting of Stockholders of the Fund and desires to
have the proposal included in the Fund's proxy statement and form of proxy for
that meeting, the stockholder must deliver the proposal to the offices of the
Fund by July 6, 2000.
