GENERAL INFORMATION
 
This Joint Proxy Statement is furnished in connection with the solicitation by
the Board of Directors of each of Nuveen Premium Income Municipal Fund, Inc.
("Premium Income"), Nuveen Municipal Market Opportunity Fund, Inc. ("Municipal
Market Opportunity"), Nuveen Premier Municipal Income Fund, Inc. ("Premier
Municipal"), Nuveen Premier Insured Municipal Income Fund, Inc. ("Premier
Insured"), Nuveen Premium Income Municipal Fund 2, Inc. ("Premium Income 2") and
Nuveen Premium Income Municipal Fund 4, Inc. ("Premium Income 4") (individually,
a "Fund" and, collectively, the "Funds"), of proxies to be voted at the Annual
Meeting of Shareholders of each Fund to be held on July 25, 1996 (for each Fund,
an "Annual Meeting" and, collectively, the "Annual Meetings"), and at any and
all adjournments thereof.
 
On the matters coming before each Fund's Annual Meeting as to which a choice has
been specified by the shareholders of that Fund on the proxy, the shares of that
Fund will be voted accordingly. If no choice is so specified, the shares of each
Fund will be voted FOR the election of the four nominees for director (or five
nominees in the case of Premium Income) to be elected by all shareholders and
the two nominees for director to be elected by holders of Remarketed Preferred
Stock, in the case of Premium Income, or Municipal Auction Rate Cumulative
Preferred Stock ("MuniPreferred(R)") in the case of the other Funds (for
convenience, shares of Premium Income's Remarketed Preferred Stock shall also be
referred to in this Joint Proxy Statement as shares of MuniPreferred), as listed
in this Joint Proxy Statement, and FOR ratification of the selection of Ernst &
Young LLP as each Fund's independent auditors. Shareholders of any Fund who
execute proxies may revoke them at any time before they are voted by filing with
that Fund a written notice of revocation, by delivering a duly executed proxy
bearing a later date, or by attending that Annual Meeting and voting in person.
 
The Board of Directors of each Fund has determined that the use of this Joint
Proxy Statement for the Fund's Annual Meeting is in the best interest of the
Fund and its shareholders in light of the similar matters being considered and
voted on by the shareholders. Shareholders of each Fund will vote separately on
each proposal relating to their Fund, and a vote on a proposal by the
shareholders of one Fund will not affect the vote on the proposal by the
shareholders of another Fund.

A quorum of shareholders is required to take action at each Fund's Annual
Meeting. A majority of the shares entitled to vote at each Annual Meeting,
represented in person or by proxy, will constitute a quorum of shareholders at
that Annual Meeting, except that for each Fund except Premium Income the
election of the two nominees to be elected by holders of MuniPreferred, 33 1/3%
of the MuniPreferred shares entitled to vote and represented in person or by
proxy will constitute a quorum. Votes cast by proxy or in person at each Annual
Meeting will be tabulated by the inspectors of election appointed for that
Annual Meeting. The inspectors of election will determine whether or not a
quorum is present at the Annual Meeting. The inspectors of election will treat
abstentions and "broker non-votes" (i.e., shares held by brokers or nominees,
typically in "street name," as to which (i) instructions have not been received
from the beneficial owners or persons entitled to vote and (ii) the broker or
nominee does not have discretionary voting power on a particular matter) as
present for purposes of determining a quorum.
 
For purposes of determining the approval of the matters submitted to the
shareholders for a vote, abstentions and broker non-votes will be treated as
shares voted against the election of directors and against ratification of the
selection of independent auditors. The details of each proposal to be voted on
by the shareholders of each Fund and the vote required for approval of each
proposal are set forth under the description of each proposal below.
 
As of May 28, 1996, there were issued and outstanding: 63,785,431 shares of
common stock and 700 shares of each series of MuniPreferred, Series A, B, C, D
and E, of Premium Income; 44,762,071 shares of common stock and 4,000 shares of
each series of MuniPreferred, Series M, T and F, of Municipal Market
Opportunity; 19,647,018 shares of common stock and 2,800 shares of each series
of MuniPreferred, Series T and TH of Premier Municipal; 19,123,476 shares of
common stock and 2,800 shares of each series of MuniPreferred, Series TH and F
of Premier Insured; 40,731,119 shares of common stock and 2,000 shares of each
series of MuniPreferred, Series M, W and F and 3,000 shares of each series of
MuniPreferred, Series T and TH of Premium Income 2; and 40,808,465 shares of
common stock and 1,328 shares of each series of MuniPreferred, Series T2 and F2,
1,680 shares of MuniPreferred, Series W, 1,800 shares of MuniPreferred, Series
F, 2,000 shares of each series of MuniPreferred, Series T and TH, and 2,200
shares of MuniPreferred, Series M Premium Income 4. Those persons who were
shareholders of record at the close of business on May 28, 1996 will be entitled
to one vote for each share held.
 
This Joint Proxy Statement is first being mailed to shareholders of the Funds on
or about June 7, 1996.

1. ELECTION OF DIRECTORS OF EACH FUND
 
At each Fund's Annual Meeting, six (6) directors, except in the case of Premium
Income in which case seven (7) directors, are to be elected to serve until the
next Annual Meeting and until their successors shall have been duly elected and
qualified. Under the terms of each Fund's Articles of Incorporation, as amended,
under normal circumstances holders of MuniPreferred are entitled to elect two
(2) directors, and the remaining directors are to be elected by holders of
common stock and MuniPreferred, voting together as a single class. The members
of the Board of Directors and the nominees for election to the Board are the
same for each Fund, except that Royce A. Hoyle is a member of the Board of
Directors and a nominee for election to the Board of Premium Income only. Table
I below shows the nominees for director of each Fund to be elected by holders of
common stock and MuniPreferred, voting together as a single class. Table II
below shows the nominees for director of each Fund to be elected by holders of
MuniPreferred only. The affirmative vote of a majority of the shares present and
entitled to vote at each Fund's Annual Meeting will be required to elect the
directors of that Fund.
 
It is the intention of the persons named in the enclosed proxy to vote the
shares represented thereby for the election of the nominees listed below unless
the proxy is marked otherwise. Each of the nominees has agreed to serve as a
director of each Fund if elected; however, should any nominee become unable or
unwilling to accept nomination or election, the proxies for each Fund will be
voted for one or more substitute nominees designated by that Fund's present
Board of Directors.
 
Tables I and II below show each nominee's age, principal occupations and other
business affiliations, the year in which each nominee was first elected or
appointed a director of each Fund and the number of shares of common stock of
the Funds and of all funds managed by Nuveen Advisory Corp. (excluding money
market funds) which each nominee beneficially owned as of April 30, 1996. All of
the nominees, except Anthony T. Dean, were last elected to the Board of
Directors at the 1995 annual meeting of shareholders. Mr. Dean will be standing
for election by each Fund's shareholders for the first time at the Annual
Meeting to fill a vacancy that will occur upon the retirement of Richard J.
Franke from John Nuveen & Co. Incorporated and the Board of Directors of the
Fund on June 30, 1996. Mr. Franke's contributions to the Funds are greatly
appreciated. As of April 30, 1996, Mr. Franke owned 1,333 shares of Premium
Income, 1,000 shares of Municipal Market Opportunity, 500 shares of Premier
Municipal, 500 shares of Premier Insured, 25,500 shares of Premium Income 2 and
26,531 shares of Premium Income 4. In addition to the vacancy that will occur
upon the retirement of Mr. Franke, there is currently another vacancy on each
Fund's Board. Each Fund's nominating committee is considering candidates for
that vacancy.
 
EACH FUND'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT
SHAREHOLDERS VOTE FOR THE ELECTION OF THE NOMINEES NAMED BELOW.

Market Opportunity. These persons have sole voting power and sole investment
power, except Mr. Schwertfeger's shares of Municipal Market Opportunity are held
jointly with his wife. In addition to the shares shown in this column, Nuveen
Advisory Corp., of which Messrs. Dean, Franke and Schwertfeger are directors,
beneficially owned 26,230 full common shares of Premium Income 4. No director
nominee beneficially owned as much as 1% of any Fund's outstanding Common Stock
or beneficially owned any shares of MuniPreferred of any of the Funds, except
that Mr. Schwertfeger's wife holds six shares of MuniPreferred of Premier
Municipal.
 
(3) The number shown reflects the aggregate number of common shares beneficially
owned in all of the NAC Funds referred to in note (1) above (excluding money
market funds).
 
The directors affiliated with John Nuveen & Co. Incorporated ("Nuveen") or
Nuveen Advisory Corp. (the "Adviser") serve without any compensation from the
Funds. Directors who are not affiliated with Nuveen or the Adviser receive a
$45,000 annual retainer for serving as a director or trustee, as the case may
be, of all funds sponsored by Nuveen and managed by the Adviser and a $1,000 fee
per day plus expenses for attendance at all meetings held on a day on which a
regularly scheduled Board meeting is held, a $1,000 fee per day plus expenses
for attendance in person or a $500 fee per day plus expenses for attendance by
telephone at a meeting held on a day on which no regular Board meeting is held,
and a $250 fee per day plus expenses for attendance in person or by telephone at
a meeting of the executive committee. The annual retainer, fees and expenses are
allocated among the funds managed by the Adviser on the basis of relative net
asset sizes, except for the annual retainer, fees and expenses paid to Mr.
Hoyle, which are allocated between Premium Income and Nuveen Municipal Value
Fund, Inc. Each Fund has adopted a Directors' Deferred Compensation Plan
pursuant to which a director of that Fund may elect to have all or a portion of
the director's fee deferred. Directors may defer fees for any calendar year by
the execution of a Participation Agreement prior to the beginning of the
calendar year during which the director wishes to begin deferral.
 
The table below shows, for each director who is not affiliated with Nuveen or
the Adviser, the aggregate compensation paid by each Fund for its fiscal year
ended October 31, 1995 and the total compensation that Nuveen funds accrued for
each director during the calendar year 1995, including any interest accrued for
directors on deferred compensation. The rate of
 
 6
   10
 
earnings on deferred compensation is equivalent to the average net earnings
rate, computed on a quarterly basis, on the shares of such Nuveen fund.

Richard J. Franke, Margaret K. Rosenheim and Timothy R. Schwertfeger currently
serve as members of the executive committee of the Board of Directors of each
Fund. The executive committee of each Fund, which meets between regular meetings
of the Board of Directors, is authorized to exercise all of the powers of the
Board of Directors. The executive committees of each Fund except Premium Income
held twelve meetings during the fiscal year ended October 31, 1995. The
executive committee of Premium Income held thirteen meetings during the fiscal
year ended October 31, 1995.
 
Each Fund's Board of Directors has an audit committee composed of Lawrence H.
Brown, Anne E. Impellizzeri, Margaret K. Rosenheim and Peter R. Sawers and, in
the case of Premium Income, Royce A. Hoyle, directors who are not "interested
persons." The audit committee reviews the work and any recommendations of the
Fund's independent auditors. Based on such review, it is authorized to make
recommendations to the Board of Directors. The respective audit committees of
the Funds held two meetings during the fiscal year ended October 31, 1995.
 
Nomination of those directors who are not "interested persons" of each Fund is
committed to a nominating committee composed of the directors who are not
"interested persons" of that Fund. It identifies and recommends individuals to
be nominated for election as non-interested directors. The nominating committees
of each Fund held one meetings during the fiscal year ended October 31, 1995. No
policy or procedure has been established as to the recommendation of director
nominees by shareholders.
 
In connection with certain legal actions described more fully on page 10 of this
Joint Proxy Statement, Premium Income has a special investigating committee
composed of Anne E. Impellizzeri and Royce A. Hoyle. The special investigating
committee, which independently
 
 7
   11
 
investigates the various claims made by plaintiffs in the litigation, held
eighteen meetings during the fiscal year ended October 31, 1995.
 
The Board of Directors of each Fund held five meetings during the fiscal year
ended October 31, 1995. During the last fiscal year, each director attended 75%
or more of each Fund's Board meetings and the committee meetings (if a member
thereof), except that Mr. Franke was unable to attend certain executive
committee meetings held solely to declare dividends. His attendance at executive
committee meetings which he was scheduled to attend was less than 75%.
 
Each Fund has the same executive officers. The following table sets forth
information as of April 30, 1996 with respect to each executive officer of the
Funds, other than executive officers who are directors and reflected above.
Officers of the Funds receive no compensation from the Funds. The term of office
of all officers will expire at the first meeting of the Board of Directors of
each Fund after the Annual Meeting, which Board of Directors' meeting is
presently scheduled to be held on July 25, 1996 for each Fund; however, as
previously mentioned, Mr. Franke will be retiring from the Board of Directors
effective June 30, 1996.

On April 30, 1996, directors and executive officers of the Funds as a group
beneficially owned the following Fund shares: Premium Income, 8,555 shares of
common stock (less than 1%) and no shares of MuniPreferred; Municipal Market
Opportunity, 6,000 shares of common stock (less than 1%) and no shares of
MuniPreferred; Premier Municipal, 500 shares of common stock and six shares of
MuniPreferred; Premier Insured, 500 shares of common stock (less than 1%) and no
shares of MuniPreferred; Premium Income 2, 25,500 shares of common stock (less
than 1%) and no shares of MuniPreferred; and Premium Income 4, 26,531 shares of
common stock (less than 1%) and no shares of MuniPreferred. On April 30, 1996,
directors, director nominees and executive officers of the Funds as a group
beneficially owned 319,589 common shares of all
 
 9
   13
 
funds managed by the Adviser (excluding money market funds). As of April 30,
1996, no person is known to the Funds to have owned beneficially more than five
percent of the shares of common stock or MuniPreferred of any Fund.
 
Certain legal actions originally filed in January 1994 by Premium Income
shareholders are pending in federal district court in Chicago against John
Nuveen & Co. Incorporated, Nuveen Advisory Corp., and the directors of the Fund
at the time of the Fund's January 1994 rights offering, alleging that the
defendants violated federal and state laws and the Fund's articles of
incorporation in connection with the rights offering and seeking unspecified
damages. A lawsuit making similar allegations was filed in 1995 against the same
defendants in state court in Minneapolis, Minnesota. The suit was dismissed in
December, 1995 and is on appeal. Fund shareholders have also filed actions in
Chicago against the Fund's former outside legal counsel and in-house counsel to
John Nuveen & Co. Incorporated and Nuveen Advisory Corp. seeking unspecified
damages and alleging, among other things, negligence and professional
malpractice. The defendants have denied the allegations and are defending the
suits. The Court in the Chicago case recently denied in large part various
motions to dismiss. The Fund's Board of Directors has created a committee,
comprised of outside directors who are not defendants in the suits, to
investigate the claims being pursued in the Fund's name and to explore all
options. The committee has completed its investigation. Based on the Committee's
investigation, the Fund, in May, 1996, filed a motion to be substituted as the
actual plaintiff and to terminate the litigation, except as to certain claims
against the Fund's adviser and outside counsel. The motion is currently pending
before the Court. While there can be no assurance as to the outcome of these
suits, based on their current status, Fund management believes that they will
not have a material adverse effect on the Fund.
 
Section 30(f) of the Investment Company Act of 1940, as amended (the "1940
Act"), and Section 16(a) of the Securities Exchange Act of 1934, as amended,
require each Fund's officers and directors, investment adviser, affiliated
persons of the investment adviser and persons who own more than ten percent of a
registered class of the Funds' equity securities to file forms reporting their
affiliation with that Fund and reports of ownership and changes in ownership of
that Fund's shares with the Securities and Exchange Commission (the "SEC") and
the New York Stock Exchange. These persons and entities are required by SEC
regulation to furnish the Funds with copies of all Section 16(a) forms they
file. Based on a review of these forms furnished to each Fund, each Fund
believes that during the fiscal year ended October 31, 1995, all Section 16(a)
filing requirements applicable to that Fund's officers and directors, investment
adviser and affiliated persons of the investment adviser were complied with.
 
2. SELECTION OF INDEPENDENT AUDITORS
 
The members of each Fund's Board of Directors who are not "interested persons"
of that Fund have unanimously selected Ernst & Young LLP, independent public
accountants, as independent auditors, to audit the books and records of that
Fund for the fiscal year ending October 31, 1996. Ernst & Young LLP has served
each Fund in this capacity since that Fund was organized and has no direct or
indirect financial interest in that Fund except as independent auditors. The
selection of Ernst & Young LLP as independent auditors of each Fund is being
submitted to the shareholders for ratification, which requires the affirmative
vote of a majority of the shares of each Fund present and entitled to vote on
the matter. A representative of Ernst & Young LLP is expected to be present at
the Annual Meetings and
 
 10
   14
 
will be available to respond to any appropriate questions raised at the Annual
Meetings and to make a statement if he or she wishes.
 
EACH FUND'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR
THE RATIFICATION OF THE SELECTION OF INDEPENDENT AUDITORS.
 
INFORMATION ABOUT THE FUNDS' INVESTMENT ADVISER
 
The Adviser, located at 333 West Wacker Drive, Chicago, Illinois, serves as
investment adviser and manager for each Fund. The Adviser is a wholly-owned
subsidiary of Nuveen, 333 West Wacker Drive, Chicago, Illinois 60606. Nuveen is
a subsidiary of The John Nuveen Company which in turn is approximately 78% owned
by The St. Paul Companies, Inc. ("St. Paul"). St. Paul is located at 385
Washington Street, St. Paul, Minnesota 55102, and is principally engaged in
providing property-liability insurance through subsidiaries. Nuveen acted as
co-managing underwriter for Premium Income, in its initial public offering of
common stock in July 1988 and its public offering of MuniPreferred in October
1988; for Municipal Market Opportunity, in its initial public offering of common
stock in March 1990 and its public offering of MuniPreferred in May 1990; for
Premier Municipal, in its initial public offering of common stock in December
1991 and its public offering of MuniPreferred in May 1992; for Premier Insured,
in its initial public offering of common stock in December 1991 and its public
offering of MuniPreferred in May 1992; for Premium Income 2, in its initial
public offering of common stock in July 1992 and its public offering of
MuniPreferred in October 1992; and for Premium Income 4, in its initial public
offering of common stock in February 1993 and its public offering of
MuniPreferred in June 1993.
 
SHAREHOLDER PROPOSALS
 
To be considered for presentation at the Annual Meeting of Shareholders of any
of the Funds to be held in 1997, a shareholder proposal must be received at the
offices of that Fund, 333 West Wacker Drive, Chicago, Illinois 60606, not later
than February 7, 1997.
 
EXPENSES OF PROXY SOLICITATION
 
The cost of preparing, printing and mailing the enclosed proxy, accompanying
notice and proxy statement, and all other costs in connection with the
solicitation of proxies, will be paid by the Funds pro rata based on the number
of shareholder accounts. Additional solicitation may be made by letter,
telephone or telegraph by officers of each Fund, by officers or employees of
John Nuveen & Co. Incorporated or Nuveen Advisory Corp., or by dealers and their
representatives. The Funds have engaged Tritech Services to assist in the
solicitation of proxies at a total estimated cost of $15,000.
 
ANNUAL REPORT DELIVERY
 
Annual reports were sent to shareholders of record of each Fund following each
Fund's fiscal year end. EACH FUND WILL FURNISH, WITHOUT CHARGE, A COPY OF ITS
ANNUAL REPORT AND SEMI-ANNUAL REPORT (WHICH WILL SOON BE AVAILABLE) UPON
REQUEST. SUCH WRITTEN OR ORAL REQUESTS SHOULD BE DIRECTED TO SUCH FUND AT 333
WEST WACKER DRIVE, CHICAGO, ILLINOIS 60606 OR BY CALLING 1-800-257-8787.
 
 11
   15
 
GENERAL
 
Management does not intend to present and does not have reason to believe that
others will present any other items of business at any Fund's Annual Meeting.
However, if other matters are properly presented to the Annual Meeting for a
vote, the proxies will be voted upon such matters in accordance with the
judgment of the persons acting under the proxies.
 
A list of shareholders entitled to be present and to vote at each Fund's Annual
Meeting will be available at the offices of the Funds, 333 West Wacker Drive,
Chicago, Illinois, for inspection by any shareholder during regular business
hours for ten days prior to the date of that Annual Meeting.
 
Failure of a quorum to be present at any Annual Meeting will necessitate
adjournment and will subject that Fund to additional expense. The persons named
in the enclosed proxy may also move for an adjournment of any Annual Meeting to
permit further solicitation of proxies with respect to any of the proposals if
they determine that adjournment and further solicitation is reasonable and in
the best interests of the shareholders. Under each Fund's By-Laws, an
adjournment of a meeting requires the affirmative vote of a majority of the
shares present in person or represented by proxy at the meeting.
 
IF YOU CANNOT BE PRESENT IN PERSON, YOU ARE REQUESTED TO FILL IN, SIGN AND
RETURN THE ENCLOSED PROXY PROMPTLY. NO POSTAGE IS REQUIRED IF MAILED IN THE
UNITED STATES.
