GENERAL INFORMATION
 
This Joint Proxy Statement is furnished in connection with the solicitation of
proxies by the Board of Directors or Board of Trustees, as the case may be (each
a "Board" and each director or trustee a "Board Member") of each of Nuveen
Multistate Tax-Free Trust ("Multistate Trust," a "Trust" or a "Company"), a
Massachusetts business trust, on behalf of its series designated Nuveen Maryland
Tax-Free Value Fund ("Maryland" or a "Fund"); Nuveen Municipal Bond Fund
("Municipal Bond Trust," a "Trust" or a "Company"), a Massachusetts business
trust, on behalf of its series designated Nuveen Municipal Bond Fund ("Municipal
Bond Fund" or a "Fund"); Nuveen Tax-Free Bond Fund, Inc. ("Tax-Free Bond Fund,"
a "Corporation" or a "Company"), a Minnesota corporation, on behalf of its
series designated Nuveen Massachusetts Tax-Free Value Fund ("Massachusetts" or a
"Fund"); Nuveen Insured Tax-Free Bond Fund, Inc. ("Insured Tax-Free Bond Fund,"
a "Corporation" or a "Company"), a Minnesota corporation, on behalf of its
series Nuveen Insured Municipal Bond Fund ("Insured Municipal Bond Fund" or a
"Fund"), Nuveen Massachusetts Insured Tax-Free Value Fund ("Massachusetts
Insured" or a "Fund") and Nuveen New York Insured Tax-Free Value Fund ("Insured
New York" or a "Fund"); and Nuveen California Tax-Free Fund, Inc. ("California
Tax-Free Fund," a "Corporation" or a "Company"), a Maryland corporation, on
behalf of its series designated Nuveen California Tax-Free Value Fund
("California" or a "Fund"), Nuveen California Insured Tax-Free Value Fund
("California Insured" or a "Fund") and Nuveen California Tax-Free Money Market
Fund ("California Money Fund" or a "Fund") to be voted at special meetings of
shareholders of the Funds, to be held on Thursday, December 12, 1996, and at any
and all adjournments thereof. This proxy statement was first mailed to
shareholders on or about November   , 1996.
 
The meetings are being called to consider a restructuring of the Funds. The
restructuring is contemplated, in part, because of an Agreement and Plan of
Merger dated as of July 16, 1996, pursuant to which The John Nuveen Company will
acquire Flagship Resources, Inc. and its subsidiaries, Flagship Financial Inc.
("Flagship") and Flagship Funds Inc. (the "Acquisition" or the "Flagship
Acquisition"). In anticipation of the Acquisition, a number of proposals are
being submitted to shareholders of the Funds (and other mutual funds in the
Flagship and Nuveen families), the net effect of which is to assimilate the
Flagship and Nuveen mutual funds into the Nuveen family of mutual funds. These
proposals are sometimes collectively referred to herein as the "Fund
Restructuring." In order to effect the Fund Restructuring, the Board of each
Fund is seeking shareholder approval of the following:
 
1. To elect eight (8) Board Members to the Board of each Company.
 
2. To approve a change in the Fund's classification from "diversified" to
"non-diversified" [For Maryland, Massachusetts and Massachusetts Insured only].
 
3. To approve proposed changes to the Fund's fundamental investment policies.
 
4. To approve an Agreement and Plan of Reorganization and the transactions
contemplated thereby, the net effect of which would be to combine each Fund into
a new series of a newly created investment company [For each Fund except
California Money Fund].

The transactions contemplated by the Fund Restructuring were presented to the
Board of each Company for consideration. The Board of each Company concluded
unanimously that each of the items comprising the Fund Restructuring is in the
best interests of the Company, the respective Funds and the shareholders of the
respective Funds.
 
The Board of each Company has fixed the close of business on October 18, 1996 as
the record date (the "Record Date") for determining holders of the Funds' shares
entitled to notice of and to vote at the meetings. Each shareholder will be
entitled to one vote for each share held. At the close of business on the Record
Date, California Money Fund had        shares outstanding and, for the other
Funds, the following shares were outstanding:

Shares of each Fund entitled to vote at a meeting that are represented by
properly executed proxies will, unless such proxies have been revoked, be voted
in accordance with the shareholders' instructions indicated on such proxies. If
no contrary instructions are received, all such shares will be voted FOR the
election of the persons who have been nominated as Board Members and FOR Items
2, 3, 4 and 5. Proxies solicited and signed in accordance with voting
instructions given by telephone or electronically transmitted instruments may be
counted if obtained pursuant to procedures designed to verify that such
instructions have been authorized.
 
A quorum of shareholders of each Company is required to take action at its
meeting. A majority of the shares entitled to vote at the meeting, represented
in person or by proxy, will constitute a quorum of shareholders. Certain other
series of Tax-Free Bond Fund and Multistate Trust will participate at the
meeting; shareholders of those series are receiving separate proxy materials.
 
Votes cast by proxy or in person at each meeting will be tabulated by the
inspector of election appointed for the meeting. The inspector of election will
determine whether or not a quorum is present at that meeting. The inspector 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
shareholders for a vote, abstentions and broker non-votes will (i) in the case
of each Trust, have no effect on the election of board members, (ii) in the case
of each Corporation, have the same effect as a vote against the election of
board members and (iii) have the same effect as a vote against Items 2, 3, 4,
and 5.
 
The details of each item to be voted upon by shareholders and the vote required
for approval of each item are set forth under the description of each item
below. Shareholders of a Fund who execute proxies may revoke them at an time
before they are voted by filing with such Fund a written notice of revocation,
by delivering a duly executed proxy bearing a later date or by attending the
meeting and voting in person.

<PAGE>   6
 
If, by the time scheduled for a meeting, a quorum of shareholders of a Company
is not present or if a quorum is present but sufficient votes in favor of any of
the items are not received, the persons named as proxies may propose one or more
adjournments of the meeting to permit further soliciting of proxies from
shareholders of the Company. Any such adjournment will require the affirmative
vote of a majority of the shares of the Company (or Fund) present (in person or
by proxy) at the session of the meeting to be adjourned. The persons named as
proxies will vote in favor of any such adjournment if they determine that such
adjournment and additional solicitation are reasonable and in the interest of
the shareholders.
 
ITEM 1. ELECTION OF BOARD OF MEMBERS
 
In order to conform the board memberships of the Nuveen family of mutual funds
after the Acquisition, the eight (8) persons shown below have been nominated to
each Company's Board. The nominees include the Company's current four
disinterested Board Members, the Company's current two interested Board Members
and two additional disinterested nominees (both of whom serve as disinterested
members of the boards of mutual funds managed by Flagship).
 
The nominees, if elected, will take office upon the consummation of the Flagship
Acquisition and their election and qualification is contingent upon consummation
of the Acquisition. The term of each person elected as a Board Member will be
from the date of the consummation of the Acquisition until the next meeting held
for the purpose of electing Board Members and until his or her successor is
elected and qualified. If the Acquisition is not consummated, the current Board
Members of each Company will continue to serve as that Company's Board.
 
All of the nominees have consented to serve as Board Members. However, if any
nominee is not available for election at the time of the meeting, the proxies
may be voted for such other person(s) as shall be determined by the persons
acting under the proxies in their discretion.
 
The following table shows each nominee who is standing for election and such
nominee's age, principal occupation or employment during the past five years and
other board memberships. The table also shows the year in which the nominee was
first elected or appointed to the Board of each company, in addition to
shareholdings in each Fund.

each Company were held for the sole purpose of declaring dividends.
 
Each Board has an audit committee composed of L. Brown, A. Impellizzeri, M.
Rosenheim and P. Sawers, disinterested Board Members of the Company. The audit
committee reviews the work and any recommendation of the Company's independent
public auditors. Based on such review, it is authorized to make recommendations

It is anticipated that, after completion of the Acquisition, each restructured
Board will elect new officers who are expected to include persons affiliated
with Nuveen and Flagship.
 
As of July 31, 1996, the Board Members and executive officers of each Company as
a group beneficially owned the following shares: 125,236 Class R shares (less
than 1%) of Municipal Bond Fund and 2,162 Class R shares (less than 1%) of
Insured Municipal Bond Fund. As of July 31, 1996, no person is known to the
Companies to have owned beneficially more than five percent of any class of any
shares of the Fund, except as set forth on Annex B.
 
VOTES REQUIRED
 
On Proposal 1, all the series of each Company will vote in the aggregate,
including, for Multistate Trust and Tax-Free Bond Fund, other series to which
this Joint Proxy Statement does not relate. In the case of each Trust, election
of Board Members requires an affirmative vote of a plurality of the shares of
the Trust present and entitled to vote at the meeting. In the case of each
Corporation, election of Board Members requires an affirmative vote of a
majority of the shares of the Corporation present and entitled to vote at the
meeting.
 
ITEM 2. CHANGE FROM "DIVERSIFIED" TO "NON-DIVERSIFIED" [FOR MARYLAND,
MASSACHUSETTS AND MASSACHUSETTS INSURED ONLY]
 
The 1940 Act divides management investment companies into two types:
"diversified" and "non-diversified." A "diversified company" is a management
company which meets the following requirements: At least 75% of the value of its
total assets is represented by cash and cash items (including receivables),
Government securities, securities of other investment companies, and other
securities for the purposes of this calculation limited in respect of any one
issuer to an amount not greater in value than 5% of the value of the total
assets of such management company and to not more than 10% of the outstanding
voting securities of such issuer. A "non-diversified company" is any management
company other than a diversified company. THE THREE APPLICABLE FUNDS ARE
CURRENTLY "DIVERSIFIED."
 
The Board of each of the applicable Companies believes that the requirements
under the 1940 Act for diversified funds may, at times, hinder these Funds'
ability to invest in attractive securities that are suitable for them,
particularly given their size and their investment focus in states that may have
a limited number of quality municipal issuers. Accordingly, each Board
recommends that shareholders of each affected Fund vote to change such Fund from
a "diversified" to a "non-diversified" fund. In connection with and as part of
this change, the Board also recommends that shareholders of each such Fund
eliminate the Fund's fundamental investment policy with respect to investing
more than a specified percentage of its assets in the securities of any one
issuer. That policy is as follows:
 
     "The Fund may not invest more than 5% of its total assets in
     securities of any one issuer, except that this limitation shall not
     apply to securities of the United States government, its agencies and
     instrumentalities or to the investment of 25% of the Fund's assets."
 
Being "non-diversified," each Fund would be able to invest its assets in the
securities of an issuer, subject only to the diversification requirements of
Subchapter M of the Internal Revenue Code. This would allow the Fund, as to 50%
of its total assets, to invest more than 5%, but not have more than 25%, in the
securities of an individual issuer. Since the Fund would be able to invest a
relatively higher percentage of its assets in the obligations of a limited
number of issuers, it may be more susceptible to any single economic, political
or regulatory occurrence than it currently is as a diversified fund.
 
VOTES REQUIRED
 
Approval of this change for a Fund requires the affirmative vote of a "majority
of the outstanding voting securities" of the Fund. The term "majority of the
outstanding voting securities" as defined in the 1940 Act means: the affirmative
vote of the lesser of (1) 67% of the voting securities of the Fund present at
the meeting if more than 50% of the outstanding shares of the Fund are present
in person or by proxy or (2) more than 50% of the outstanding shares of the
Fund.

ITEM 3. PROPOSED CHANGES IN FUNDAMENTAL INVESTMENT POLICIES [FOR EACH FUND
EXCEPT CALIFORNIA MONEY FUND]
 
The Board of each of the Companies has proposed that a number of fundamental
investment policies of each applicable Fund be amended. The primary purpose of
this proposal is to revise the Funds' fundamental investment policies to conform
them to those that are expected to become standard for all the municipal bond
funds managed or to be managed by Nuveen Advisory (including the Flagship Funds)
and to provide Nuveen Advisory with additional flexibility in managing the
Funds' assets. Nuveen Advisory believes that increased standardization will help
to promote operational efficiencies in part by making it easier for the
contemplated assimilation of the Flagship and Nuveen mutual funds into combined
prospectuses. In addition, standardization will facilitate the monitoring of
compliance with the fundamental investment policies of the Funds.
 
Because each of proposed changes are designed to standardize the Funds'
fundamental investment policies across the Nuveen complex, they are set forth as
a single proposal. Below is a summary of each of the proposed changes. The
actual policies for each Fund, as they are proposed to be changed, are set forth
in Annex C.
 
AMT BONDS.  Each Fund has a fundamental investment policy that it may invest up
to 20% of its net assets in Municipal Obligations that pay interest subject to
the federal alternative minimum tax ("AMT Bonds"). Under the proposal, the 20%
limitation on AMT Bonds would be eliminated. This would allow each Fund to
invest an unlimited amount in AMT Bonds, the interest on which is a specific tax
preference item for purposes of computing the alternative minimum tax on
corporations and individuals. If your tax liability is determined under the
alternative minimum tax, you will be taxed on your share of the Fund's
exempt-interest dividends that were paid from income earned on AMT Bonds. In
addition, the alternative minimum taxable income for corporations is increased
by 75% of the difference between an alternative measure of income ("adjusted
current earnings") and the amount otherwise determined to be alternative minimum
taxable income. Interest on all Municipal Obligations and therefore all
distributions by the Fund that would otherwise be tax exempt is included in
calculating a corporation's adjusted current earnings. Nuveen Advisory and the
Boards believe that there are possible attractive investment opportunities from
AMT Bonds and that the Funds should not be limited in quantity to their purchase
of such securities.
 
INVESTMENT GRADE QUALITY RATINGS.  Each of the Funds has differing fundamental
policies setting forth the quality parameters requirements for the Fund's
assets.
 
Maryland is limited to: Municipal Obligations rated investment grade or better
by Moody's or S&P; unrated Municipal Obligations of investment grade quality in
the opinion of Nuveen Advisory, limited to no more than 20% of the Fund's
assets; and "temporary investments".
 
Municipal Bond Fund is limited to: Municipal Obligations rated investment grade
or better by Moody's or S&P; unrated Municipal Obligations of investment grade
quality in the opinion of Nuveen Advisory, limited to no more than 10% of the
Fund's assets; and "temporary investments".
 
Massachusetts and California are each limited to: Municipal Obligations rated
investment grade or better by Moody's or S&P; invested municipal obligations of
investment grade quality in the opinion of Nuveen Advisory, with no fixed
percentage limitations on these unrated Municipal Obligations; and temporary
investments.
 
In addition to the requirement that they invest substantially all (at least 80%)
of their assets in insured Municipal Obligations, each of Insured Municipal Bond
Fund, Insured Massachusetts and Insured New York are limited to: Municipal
Obligations rated investment grade or better by Moody's or S&P; and unrated
Municipal Obligations of investment grade quality in the opinion of Nuveen
Advisory, with no fixed percentage limitations on those unrated Municipal
Obligations.
 
Under the proposal, Fitch Investments Service, Inc. ("Fitch") would be added to
each Fund's policies for purposes of determining investment grade quality
Municipal Obligations, and for Maryland and Municipal Bond Fund, the percentage
limits on the amount of unrated investment grade quality Municipal Obligations
that could be purchased would be eliminated. This would allow each Fund to rely
on ratings from Fitch for purposes of determining whether a Municipal Obligation
is investment grade quality, and, in the case of Maryland and Municipal Bond
Fund, increase the permitted amount of unrated investment grade quality
Municipal Obligations. Fitch is a nationally recognized statistical rating
organization, with a particular emphasis on rating Municipal Obligations. As a
consequence of the proposal, the Funds could invest an unlimited amount in
Fitch-only investment grade securities and, in the case of Maryland and
Municipal Bond Fund, may invest an unlimited amount in unrated Municipal
Obligations that Nuveen Advisory believes are investment grade quality.
 
ILLIQUID SECURITIES.  Each Fund's (except for Municipal Bond Fund's) current
fundamental investment policy on purchasing "illiquid" securities is as follows:
 
     "The Fund may not invest more than 10% of its total assets in repurchase
     agreements maturing in more than seven days, "illiquid" securities (such as
     non-negotiable CDs) and securities without readily available market
     quotations."
 
Municipal Bond Fund's fundamental investment policy on purchasing "illiquid"
securities is as follows:
 
     "The Fund may not invest more than 10% of its total assets in securities
     that the Fund is restricted from selling to the public without registration
     under the Securities Act of 1933."
 
 7
<PAGE>   11
 
Under the proposal, the fundamental limitation on illiquid securities would be
eliminated, and it would be replaced with the following non-fundamental policy,
which could be changed without a vote of the shareholders:
 
     "The Fund may not invest more than 15% of its net assets in "illiquid"
     securities."
 
This would conform each Fund's policy on illiquid securities to the current
position of the Securities and Exchange Commission ("SEC"). In particular,
current SEC guidelines provide that the usual limit on aggregate holdings by an
open-end investment company of illiquid assets is 15% of its net assets. This
limit stems from the SEC's concern that if a mutual fund holds a material
percentage of its assets in securities or other assets for which there is no
established market, there may be a question concerning the ability of the fund
to make payment within seven days of the date its shares are rendered for
redemption. In addition, by making each Fund's policy non-fundamental, a result
of the proposal would be to allow the Fund to make future changes without
shareholder approval. The Boards believes that this would enable the Funds to
respond more quickly to legal, regulatory and market developments. Any changes
to a Fund's illiquid securities limitations would, however, remain subject to
applicable regulatory requirements.
 
UNSEASONED ISSUERS.  Each Fund has a fundamental investment policy that it will
not invest more than 5% of its total assets in securities of unseasoned issuers
which, together with their predecessors, have been in operation for less than
three years. Under the proposal, this restriction would be eliminated. The
original purpose of this policy was to comply with state laws intended to limit
the risks associated with investing in companies that have no proven long-term
track record in business and whose prospectus are uncertain.
 
The Funds believe that this restriction no longer, or soon will no longer be,
required by applicable state law. Moreover, Nuveen Advisory believes that this
restriction was not intended to apply to municipal issuers (or other
governmental issuers), but rather was intended to apply only to securities of
non-governmental issuers such as common stock of operating companies.
Accordingly, the restriction is proposed to be eliminated; however, to the
extent any applicable state law would still require this or any similar
restriction, the Funds intend to comply with such state law.
 
AVERAGE MATURITY.  Each Fund has a fundamental investment policy that it intends
to emphasize investments in Municipal Obligations with long-term maturities in
order to maintain an average portfolio maturity of 20-30 years, but that the
average portfolio maturity may be shortened from time to time in order to help
limit the Fund's exposure to market risk. Under the proposal, the target
maturity range would be changed from 20-30 years to 15-30 years, and the Fund's
policy regarding maturities would be designated as non-fundamental. Although the
Funds have no current intention to do so, the non-fundamental policy could be
changed in response to regulatory, market, legal or other developments without
further approval by shareholders.
 
TEMPORARY INVESTMENTS.  Each Fund has a fundamental investment policy that it
will not invest in securities other than "Municipal obligations" and "temporary
investments," as those terms are defined in the prospectus. The prospectus
defines temporary investments to include taxable temporary investments that are
rated within the "highest" grade by Moody's or S&P. Under the proposal, Fitch
would be added to each Fund's policies for purposes determining the quality
level of taxable temporary investments and the category of taxable temporary
investments would be expanded to include those that are rated within the two
highest grades (as opposed to the "highest" grade) by Moody's, S&P or Fitch.
 
DIVERSIFICATION LIMIT (MUNICIPAL BOND FUND ONLY).  Municipal Bond Fund has a
fundamental investment policy regarding diversification that prohibits the Fund
from investing more than 5% of its total assets in securities of any one issuer,
except that this limitation does not apply to securities of the United States
Government, its agencies and instrumentalities. Under the proposal, this policy
would be revised to add a 25% "basket" (i.e., this limitation would also not
apply to the investment of 25% of the investments).
 
Some states at one time prohibited a fund from registering shares for sale if
the fund intended to invest more than 5% of total assets in a single issuer. The
Fund's current fundamental policy was adopted to address these state
regulations. Because the state regulations regarding these limitations have been
eliminated, shareholder approval is sought to provide the Fund a limited ability
to invest a higher proportion of its assets in securities issued by a single
issuer.
 
Under the proposal, the Fund would be required to invest 75% of its total assets
so that no more than 5% of its total assets would be invested in any one issuer.
As to the remaining 25% of total assets, there would be no fundamental
investment limitation on the amount of assets the Fund could invest in a single
issuer's securities. This would permit the Fund for example, to invest 25% of
its total assets in securities of one issuer or to invest 10% of the total
assets in the securities of one issuer and 15% in securities of another issuer.
The other Nuveen funds and the "diversified" Flagship funds all have this
limited ability to concentrate their investments; the "non-diversified" funds
have a greater ability to concentrate their investments, as described in Item 2
above.
 
The primary purpose of the proposal is to give the Fund greater investment
flexibility by permitting it to acquire larger positions in the securities of
individual issuers, and to bring this Fund's policies in line with those of the
other "diversified" funds in the Nuveen Flagship fund family. Nuveen Advisory
believes that this increased flexibility may provide opportunities to enhance
the Fund's performance consistent with the Fund's stated investment objective.
At the same time, investing a larger percentage of the Fund's assets in a single
issuer's securities increases the Fund's exposure to credit and other risks
associated with that issuer's financial conditions and business operations
including risk of default on debt securities.

<PAGE>   12
 
Nuveen Advisory will only invest more than 5% of the Fund's total assets in an
issuer's securities when it believes the securities' potential return justifies
accepting the risks involved.
 
SINGLE BANK LIMITS.  Each Fund has a fundamental investment policy that it will
not hold securities of a single bank, including securities backed by a letter of
credit of such bank, if such holdings would exceed 10% of the total assets of
the Fund. Under the proposal, this fundamental investment policy would be
eliminated, and each Fund would be limited in its bank holdings solely by its
policies with respect to diversification.
 
BORROWING (MUNICIPAL BOND FUND ONLY).  Municipal Bond Fund has a fundamental
investment policy that it will not borrow money, except for temporary or
emergency purposes and not for investment purposes and then only in an amount
not exceeding 5% of the value of the Fund's assets at the time of borrowing.
Under the proposal, this borrowing limit would be increased to 10% generally and
to one-third (33 1/3%) in order to meet redemption requests which might
otherwise require the untimely disposition of securities.
 
While this proposal increases the ability of the Fund to borrow, it still limits
borrowings to temporary or emergency purposes. In addition, under the proposal,
while any such borrowings exceed 5% of the Fund's total assets, no additional
purchases of investment securities could be made by the Fund. If, due to market
fluctuations or other reasons, the value of the Fund's assets falls below 300%
of its borrowings, the Fund would reduce its borrowings within 3 business days.
To do this, the Fund may have to sell a portion of its investments at a time
when it may be disadvantageous to do so. Finally, as a matter of clarification,
the proposal excludes permitted borrowings from the definition of "senior
securities" under the Fund's fundamental investment policy that prohibits the
issuance of senior securities as defined in the 1940 Act.
 
FUTURES AND OPTIONS (MUNICIPAL BOND FUND ONLY).  Municipal Bond Fund has
fundamental investment policies that may prohibit the Fund from entering into
futures and options transactions for hedging purposes. Specifically, the
policies prohibit the Fund from (1) purchasing or selling commodities or
commodity contracts, (2) writing or purchasing puts, calls, straddles, spreads
or any combinations thereof, and (3) issuing senior securities as defined in the
1940 Act. Under the proposal, each of these policies would be amended to exclude
from the general prohibitions transactions involving futures and/or options as
they will be set forth in the Fund's Prospectus and Statement of Additional
Information (and as set forth in Annex D). The Fund would be permitted to engage
in certain futures and options transactions for hedging purposes only.
 
Although the Fund does not currently intend to enter into futures and options
transactions, the Board believes that the Fund's current policies prohibiting
these instruments unnecessarily restricts the Fund from taking advantage of
potential risk management techniques that may be desirable at a later time.
 
The Board has determined that the ability to invest in these instruments would
provide this Fund with additional means for seeking to hedge the value of its
portfolio, i.e., attempting to reduce the overall level of investment risk that
normally would be expected to be associated with the Fund's portfolio and to
attempt to protect itself against market movements that might adversely affect
the value of the Fund's securities or the price of securities that the Fund is
considering purchasing. The other funds in the Nuveen and the Flagship fund
families already have the ability to use futures and options for hedging
purposes. The Board believes that the Fund would benefit from having the
flexibility to purchase and sell futures and options, in addition to its other
investments, in the same manner as the other Nuveen Flagship funds, and that the
Fund's investments in these instruments would be consistent with the Fund's
investment objective and policies. There can be no assurance, however, that the
use of these instruments by the Fund will assist it in achieving its investment
objective. A summary of the potential uses and risks of futures and options, and
the strategies that may be employed by the Fund with respect to these
instruments if this proposal is approved by shareholders, is set forth in Annex
D attached hereto.
 
VOTES REQUIRED
 
Approval of the proposed changes in fundamental investment policies for a Fund
requires the affirmative vote of a "majority of the outstanding voting
securities" of the Fund. The term "majority of the outstanding voting
securities" as defined in the 1940 Act means: the affirmative vote of the lesser
of (1) 67% of the voting securities of the Fund present at the meeting if more
than 50% of the outstanding shares of the Fund are present in person or by proxy
or (2) more than 50% of the outstanding shares of the Fund.
 
ITEM 4. PROPOSED REORGANIZATION [FOR EACH FUND EXCEPT CALIFORNIA MONEY FUND]
 
The Board of each Company unanimously approved an Agreement and Plan of
Reorganization (the "Reorganization Agreement") for each Fund (except California
Money Fund) in the form attached hereto as Annex A. The Reorganization Agreement
provides for the reorganization (the "Reorganization") of each Fund into a new
series of a newly created Massachusetts business trust.
 
The purpose of the Reorganization is to assimilate the Fund into the Nuveen
family of mutual funds in a structure that provides for a uniform set of charter
documents, shareholder purchase options and shareholder account privileges.
Nuveen Advisory believes that increased standardization of documents and
operational policies will help to promote operational efficiencies, to allocate
work flows and to allow for future change, which should benefit the Funds. The
Board considered all

material issues associated with the Reorganization and determined that the
Reorganization is in the best interests of shareholders. The table below shows
the structure of the Funds before and after the Reorganizations.

 * Series to which this Joint Proxy Statement does not relate.
 
** The California Money Fund will not participate in the Reorganization, and
   will remain a series of the Nuveen California Tax-Free Fund, Inc.
 
Each Reorganization contemplates that the Fund will transfer all its assets to a
series ("New Fund") of a newly created Massachusetts business trust (the "New
Trust") and the liabilities of the Fund will be assumed by the New Fund and each
shareholder of the Fund will receive for such shareholder's shares an equal
number of shares (including any fractional share) of equal value of the New
Fund.
 
If shareholders of a Fund do not approve the Reorganization, the Fund will
continue in business as a series of its respective Company.
 
PROCEDURES FOR REORGANIZATION. In connection with the Reorganization, after the
close of business on the date of effectiveness of the Reorganization (the
"Effective Date") but prior to its completion, one share of each class of the
New Fund will be issued to the Fund. The Fund, as the sole shareholder of each
class of the New Fund, will then take the following actions:
 
     (1) approve a proposed new investment advisory agreement on behalf of the
         respective class of the New Fund on the same terms as the existing
         agreement;
 
     (2) approve a proposed new Rule 12b-1 Plan on behalf of the respective
         class of the New Fund, which is described in greater detail below; and
 
 10
<PAGE>   14
 
     (3) ratify the selection of Arthur Andersen LLP as auditors for the New
Fund; and
 
     (4) ratify the election as board members of the New Trust of the same
         persons who are nominated as Board Members in Item 1 (if such persons
         are approved by shareholders).
 
Thereafter, on the Effective Date, the Fund will transfer all its assets to the
New Fund and the New Fund will assume all the liabilities of the Fund and issue
to each shareholder of the Fund shares of the same class of the New Fund in a
number equal to the number of shares (including any fractional share) of the
Fund then owned by such shareholder and having the same NAV per share as the NAV
of the close on the Effective Date, in exchange for all the shares of that class
of the Fund owned by the shareholder, and the Fund will then terminate. A
shareholder of the Fund will therefore acquire the same pro rata interest in the
New Fund as of the effective time of the Reorganization as the shareholder had
in the Fund immediately prior to the Reorganization. The New Fund will then
operate in the same manner and with the same investment objectives and policies
of the Fund, giving effect to the results of the shareholder votes on the other
items, including the change of fundamental investment policies.
 
Confirmations of the shares of the New Fund received in the Reorganization in
exchange for shares of the Fund will not be issued to shareholders because the
number and value of shares held by a shareholder will not be changed by the
Reorganization.
 
It will not be necessary for a shareholder holding certificates of a Fund to
exchange those certificates for new certificate representing shares of the New
Fund following consummation of the Reorganization. Certificates for shares of a
Fund issued prior to the Reorganization will represent shares of the New Fund
after the Reorganization.
 
If approved by shareholders of the Fund, it is expected that the Reorganization
will be made effective on January 31, 1997, but it may be effective at a
different time.
 
PROPOSED NEW RULE 12B-1 PLAN. Rule 12b-1 under the 1940 Act (the "Rule")
provides among other things, that an open-end investment company (mutual fund)
may bear expenses of distributing its shares only pursuant to a plan (a "Rule
12b-1 Plan") adopted in accordance with the Rule. John Nuveen & Co.
Incorporated, acting as principal underwriter and distributor for each Company,
distributes the Funds' Class A Shares, Class C Shares and Class R Shares. The
Class A Shares and the Class C Shares are currently subject to a Rule 12b-1
Plan. The Class R Shares are not currently subject to a Rule 12b-1 Plan.
 
As part of the Fund Restructuring, each Board approved the issuance of Class B
Shares and a proposed new Rule 12b-1 Plan for Class A and Class C Shares. The
proposed Rule 12b-1 Plan for the New Fund will be substantively the same for
Class A and Class C shares as the existing plan with the exception that for both
the Class A Shares and the Class C Shares the fees will be reduced and for the
current Class C Shares the operation of the conversion feature will be modified.
Specifically, under the current Rule 12b-1 Plan, the service fee is .25% for
both Class A and Class C Shares; under the new Rule 12b-1 plan, the service fee
will be .20%. In addition, Class C Shares currently have a .75% distribution
fee; under the new Rule 12b-1 plan the distribution fee will be .55% for Class C
Shares.

The table below shows the fees paid by each Fund to John Nuveen & Co.
Incorporated for its Class C Shares, in the case of each Fund except Maryland,
for the fiscal year ended February 29, 1996, and in the case of Maryland, for
the fiscal year ended January 31, 1996 and the fees that would have been paid
(pro forma) had the new Rule 12b-1 plan had been in effect during the same
periods.

Class C Shares currently convert automatically to Class A Shares six years after
purchase. All such conversions are done at net asset value without the
imposition of any sales load, fee, or other charge, so that the value of each
shareholder's account immediately before conversion will be the same as the
value of the account immediately after conversion. Class C Shares acquired
through reinvestment of distributions convert into Class A Shares based on the
date of the initial purchase to which such shares relate. The automatic
conversion of Class C Shares to Class A Shares six years after purchase was
designed to ensure that holders of Class C Shares would pay over the six-year
period a distribution fee that is approximately the economic equivalent of the
one-time, up-front sales charge paid by holders of Class A Shares on purchases
of up to $50,000. Class C Shares that are converted to Class A Shares are no
longer subject to an annual distribution fee, but remain subject to an annual
service fee which is identical in amount for both Class C Shares and Class A
Shares.
 
Under the proposed Rule 12b-1 Plan, Class C shareholders who purchased their
shares prior to the Effective Date of the Reorganization will still retain the
option to convert their shares to Class A Shares at the end of their six-year
holding period on the same basis as described above, ALTHOUGH THE CONVERSION
WILL NO LONGER OCCUR AUTOMATICALLY. SHAREHOLDERS WILL NEED TO EXERCISE THIS
CONVERSION FEATURE BY SUBMITTING A REQUEST FOR CONVERSION TO THE FUND OR ITS
TRANSFER AGENT AFTER THE SIX YEARS HAVE ELAPSED. Under the proposed Rule 12b-1
Plan, Class C shareholders who purchase their shares after the Reorganization
will not have a conversion feature.
 
CERTAIN PROVISIONS IN THE NEW TRUST'S DECLARATION OF TRUST. Under Massachusetts
law, shareholders of a New Fund could, under certain circumstances, be held
personally liable for the obligations of that Fund. However, the New Trust's
Declaration contains an express disclaimer of shareholder liability for acts or
obligations of a New Fund and requires that notice of such disclaimer be given
in each agreement, obligation or instrument entered into or executed by the New
Trust or the trustees. The New Trust's Declaration further provides for
indemnification out of the assets and property of the New Trust for all loss and
expense of any shareholder held personally liable for the obligations of the New
Trust. Thus, the risk of a shareholder incurring a loss due to shareholder
liability is limited to circumstances in which the New Trust would be unable to
meet its obligations. The New Trust believes that the likelihood of such
circumstances is extremely remote.
 
 12
<PAGE>   16
 
The New Trust's Declaration provides that the obligations of the New Trust are
not binding upon the trustees individually, but only upon the assets and
property of the New Trust, and that the trustees shall not be liable for errors
of judgment or mistakes of fact or law. Nothing in the New Trust's Declaration,
however, protects a trustee against any liability to which he or she would
otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of his or
her office.
 
CERTAIN COMPARATIVE INFORMATION ABOUT THE NEW TRUSTS AND THE COMPANIES. Each New
Trust and each Trust are organized as business trusts under the laws of the
Commonwealth of Massachusetts. Tax-Free Bond Fund and Insured Tax-Free Bond Fund
are organized as corporations under the laws of the State of Minnesota.
California Tax-Free Fund is organized as a corporation under the laws of
Maryland. The provisions of the Declaration of Trust of each New Trust are
substantially similar to the provisions of the Declaration of Trust of each
Trust; except that the Declarations provide, for the New Trust, that 30% of the
outstanding shares constitutes a quorum at shareholders meetings, whereas for
each Trust, that a majority of the outstanding shares is necessary for a quorum
at shareholders meetings. The provisions of the Declaration of Trust of each New
Trust are substantially similar to the provisions of the Articles of
Incorporation of each Company; except the Declaration of the New Trust provides
for removal of trustees for cause only by vote of 66 2/3% of the remaining
trustees or shareholders, whereas a majority of shareholders of the Corporation
can remove a director with or without cause; under the New Trust, 30% of the
outstanding shares constitutes a quorum at shareholders meetings, whereas a
majority of the outstanding shares of the Corporation is necessary for a quorum
at shareholders meetings; under the New Trust, the Trust (or a series) can be
terminated (i) by the trustees, upon notice to the shareholders, (ii) by a
majority vote of shareholders when recommended by the trustees, or (iii) by
66 2/3% of the shareholders, whereas the Corporation (or a series thereof) may
be terminated by action of a majority of the affected shareholders; under the
Declaration of the New Trust, trustees may be elected by a plurality of votes
cast when a quorum is present, whereas directors of the Corporation may only be
elected by the vote of a majority of a quorum; the Declaration of the New Trust
(other than the Article regarding Trustees which can only be amended by a
66 2/3% vote of shareholders) can be amended by vote of a majority of trustees
and a majority of the shareholders, whereas an amendment to the Articles of the
Corporation would require a 66 2/3% vote of the shareholders if the amendment
would change material rights (such as preferences) with respect to shares,
distributions or liquidation rights.
 
FEDERAL INCOME TAX CONSEQUENCES. It is anticipated that the transactions
contemplated by the Reorganization will be tax-free for federal income tax
purposes. Each Fund has received an opinion of Vedder, Price, Kaufman &
Kammholz, that under the Internal Revenue Code of 1986 the reorganization of the
Fund into the New Fund pursuant to the Reorganization will not give rise to the
recognition of income, deductions, gain or loss for federal income tax purposes
to the Fund, the Company, or the shareholders of the Fund. A shareholder's
adjusted basis for tax purposes in shares of the New Fund after the
Reorganization will be the same as his adjusted basis for tax purposes in the
shares of the Fund immediately before the Reorganization. The holding period of
the shares of the New Fund received by the shareholders of the Fund will include
the holding period of shares of the Fund exchanged therefor, provided that at
the time of the exchange the shares of the Fund were held as capital assets.
 
VOTES REQUIRED
 
Approval of the Reorganization for a Fund (other than Maryland and Municipal
Bond Fund) requires the affirmative vote of [a majority of the shares
outstanding] of the Fund. Approval of the Reorganization for each of Maryland
and Municipal Bond Fund requires the affirmative vote of a "majority of the
outstanding voting securities" of the Fund. The term "majority of the
outstanding voting securities" as defined in the 1940 Act means: the affirmative
vote of the lesser of (1) 67% of the voting securities of the Fund present at
the meeting if more than 50% of the outstanding shares of the Fund are present
in person or by proxy or (2) more than 50% of the outstanding shares of the
Fund. Each Reorganization is contingent upon the shareholders of the applicable
Company electing those persons who are nominated as Board Members in Item 1.

ANNEX A
 
FORM OF AGREEMENT AND PLAN OF REORGANIZATION
 
[Name of Company] (the "Company"), a [Massachusetts business trust, Minnesota
corporation, Maryland corporation], on behalf of its series of shares designated
               (the "Fund") and [Name of New Trust] (the "New Trust"), a
Massachusetts business trust, on behalf of its series of shares designated
               (the "New Fund"), agree upon the following plan of
reorganization:
 
1. The Fund shall transfer to the New Fund all of the assets of the Fund
(including the share(s) of the New Fund owned by the Fund, which shall be
cancelled), in exchange for which the New Fund shall simultaneously assume all
of the liabilities of the Fund, and shall issue directly to the shareholders of
the Fund shares of the New Fund in a number and net asset value of each class
equal to the aggregate number and net asset value of shares of such class
(including fractional shares) of the Fund then outstanding, in a distribution in
which each registered shareholder of the Fund shall receive shares of the New
Fund in a number and net asset value of each class equal to the number and net
asset value of shares (including any fractional share) of the Fund of such class
then owned by the shareholder, in exchange for and cancellation of the
shareholder's shares of the Fund.
 
2. The distribution to the shareholders of the Fund shall be accomplished by
establishing an account on the share records of the New Fund in the name of each
registered shareholder of the Fund, and crediting that account with a number of
shares of each class the New Fund equal to the number of shares (including any
fractional share) of the Fund of such class owned of record by the shareholder
at the time of the distribution. Outstanding certificates representing shares of
the fund shall thereafter represent an equal number of shares of the Series.
 
3. Promptly thereafter, the Fund shall be terminated.
 
4. The transaction in section 1 above shall occur on January 31, 1997 at
p.m., Chicago time, at the offices of the New Trust, or at such other date, time
or place as may be agreed upon by the parties.
 
5. This agreement may be amended at any time, and may be terminated at any time
before the completion of the transaction in section 1, regardless of whether or
not this agreement and plan of reorganization has been approved by the
shareholders of the Fund, by agreement of the Company and the New Trust,
provided that no amendment shall have a material adverse effect upon the
interests of shareholders of the Fund. In any case, this agreement and plan of
reorganization may be terminated by either the Company or the New Trust, if the
transaction in section 1 has not occurred by the close of business on June 30,
1997.
 
6. [For Companies organized as Massachusetts business trusts only: A copy of the
Company's Declaration of the Trust is on file with the Secretary of the
Commonwealth of Massachusetts, and notice is hereby give that this instrument is
executed on behalf of the trustees of the Company as the trustees of the Company

PROPOSED CHANGES IN FUNDAMENTAL POLICIES
(ADDITIONS UNDERLINED; DELETIONS STRICKEN; * * * INDICATES SKIPS IN TEXT OF
POLICY)
 
                      NUVEEN MARYLAND TAX-FREE VALUE FUND
 
The Fund's investment assets will consist of:
 
     -  Municipal Obligations rated investment grade at the time of purchase
        (Baa or BBB or better by Moody's Investors Service, Inc. ("Moody's") or,
        Standard and Poor's Corporation ("S&P") ) or Fitch Investments Service,
        Inc. ("Fitch"));
 
     -  unrated Municipal Obligations of investment grade quality in the opinion
        of Nuveen Advisory, limited to no more than 20% of the Fund's net assets
        with no fixed percentage limitations on these unrated Municipal
        Obligations; and
 
     -  temporary investments within the limitations and for the purposes
        described below.
 
Municipal Obligations rated Baa are considered by Moody's to be medium grade
obligations which lack outstanding investment characteristics and in fact have
speculative characteristics as well, while Municipal Obligations rated BBB are
regarded by S&P as having an adequate capacity to pay principal and interest and
Municipal Obligations rated BBB are regarded by Fitch to be investment grade and
of satisfactory credit quality with an adequate capacity to pay principal and
interest. The Fund may invest up to 20% of its net assets in Municipal
Obligations that pay interest subject to the federal alternative minimum tax
("AMT Bonds"). The Fund intends to emphasize investments in Municipal
Obligations with long-term maturities in order to maintain an average portfolio
maturity of 20-30 years, but the average maturity may be shortened from time to
time depending on market conditions in order to help limit the Fund's exposure
to market risk. As a result, the Fund's portfolio at any given time may include
both long-term and intermediate-term Municipal Obligations.
 
Under ordinary circumstances, the Fund will invest substantially all (at least
80%) of its net assets in its respective state's Municipal Obligations, and not
more than 20% of its net assets in "temporary investments," described below,
provided that temporary investments subject to regular federal income tax and
AMT Bonds may not comprise more than 20% of the Fund's net assets. For defensive
purposes, however, in order to limit the exposure of its portfolio to market
risk from temporary imbalances of supply and demand or other temporary
circumstances affecting the municipal market, the Fund may invest without limit
in temporary investments. The Fund will not be in a position to achieve its
investments objective of tax-exempt income to the extent it invests in taxable
temporary investments.
 
The foregoing investment policies are fundamental policies of the Fund and may
not be changed without the approval of the holders of a majority of the shares
of the Fund.
 
The Fund intends to emphasize investments in Municipal Obligations with
long-term maturities in order to maintain an average portfolio maturity of 15-30
years, but the average maturity may be shortened from time to time depending on
market conditions in order to help limit the Fund's exposure to market risk. As
a result, the Fund's portfolio at any given time may include both long-term and
intermediate-term Municipal Obligations.
 
                             * * * * * * * * * * *
 
As described above, the Fund under ordinary circumstances may invest up to 20%
of its net assets in "temporary investments," but may invest without limit in
temporary investments during temporary defensive periods. The Fund will seek to
make temporary investments in short-term securities the interest on which is
exempt from regular federal income tax, but may be subject to state income tax
in the Fund's respective state. If suitable federally tax-exempt temporary
investments are not available at reasonable prices and yields, the Fund may make
temporary investments in taxable securities whose interest is subject to both
state and federal income tax. The Fund will invest only in those taxable
temporary investments that are either U.S. Government securities or are rated
within the two highest grade grades by Moody's or, S&P or Fitch, and mature
within one year from the date of purchase or carry a variable or floating rate
of interest. See the Statement of Additional Information for further information
about the temporary investments in which the Fund may invest.
 
                             * * * * * * * * * * *
 
The Fund, as a fundamental policy, may not, without the approval of the holders
of a majority of the shares of the Fund:
 
                             * * * * * * * * * * *
 
     (12) Invest more than 5% of its total assets in securities of unseasoned
          issuers which, together with their predecessors, have been in
          operation for less than three years;
 
 C-1
<PAGE>   21
 
                             * * * * * * * * * * *
 
     (14) Invest more than 10% of its total assets in repurchase agreements
          maturing in more than seven days, "illiquid" securities (such as
          non-negotiable CDs) and securities without readily available market
          quotations;
 
                             * * * * * * * * * * *
 
It is a fundamental policy of the Fund, which cannot be changed without the
approval of the holders of a majority of shares of such Fund, that the Fund will
not hold securities of a single bank, including securities backed by a letter of
credit of such bank, if such holdings would exceed 10% of the total assets of
such Fund.

                           NUVEEN MUNICIPAL BOND FUND
 
The Fund's investment assets will consist of:
 
     -  Municipal Obligations rated investment grade at the time of purchase
        (Baa or BBB or better by Moody's Investors Service, Inc. ("Moody's") or,
        Standard and Poor's Corporation ("S&P")) or Fitch Investments Service,
        Inc. ("Fitch"));
 
     -  unrated Municipal Obligations of investment grade quality in the opinion
        of Nuveen Advisory, limited to no more than 10% of the Fund's net assets
        with no fixed percentage limitations on these unrated Municipal
        Obligations; and
 
     -  temporary investments within the limitations and for the purposes
        described below.
 
Municipal Obligations rated Baa are considered by Moody's to be medium grade
obligations which lack outstanding investment characteristics and in fact have
speculative characteristics as well, while Municipal Obligations rated BBB are
regarded by S&P as having an adequate capacity to pay principal and interest and
Municipal Obligations rated BBB are regarded by Fitch to be investment grade and
of satisfactory credit quality with an adequate capacity to pay principal and
interest. Although the Fund to date has not done so and has no present intention
of doing so, the Fund may invest up to 20% of its net assets in Municipal
Obligations that pay interest subject to the federal alternative minimum tax
("AMT Bonds"). The Fund intends to emphasize investments in Municipal
Obligations with long-term maturities in order to maintain an average portfolio
maturity of 20-30 years, but the average maturity may be shortened from time to
time depending on market conditions in order to help limit the Fund's exposure
to market risk. As a result, the Fund's portfolio at any given time may include
both long-term and intermediate-term Municipal Obligations.
 
Under ordinary circumstances, the Fund will invest substantially all (at least
80%) of its net assets in Municipal Obligations, and not more than 20% of its
net assets in "temporary investments," described below, provided that temporary
investments subject to regular federal income tax and AMT Bonds may not comprise
more than 20% of the Fund's net assets. For defensive purposes, however, in
order to limit the exposure of its portfolio to market risk from temporary
imbalances of supply and demand or other temporary circumstances affecting the
municipal market, the Fund may invest without limit in temporary investments.
The Fund will not be in a position to achieve its investment objective of
tax-exempt income to the extent it invests in taxable temporary investments.
 
The foregoing investment policies are fundamental policies of the Fund and may
not be changed without the approval of the holders of a majority of the shares
of the Fund.
 
The Fund intends to emphasize investments in Municipal Obligations with
long-term maturities in order to maintain an average portfolio maturity of 15-30
years, but the average maturity may be shortened from time to time depending on
market conditions in order to help limit the Fund's exposure to market risk. As
a result, the Fund's portfolio at any given time may include both long-term and
intermediate-term Municipal Obligations.

of its net assets in "temporary investments," but may invest without limit in

If suitable tax-exempt temporary investments are not available at reasonable
prices and yields, the Fund may make temporary investments in taxable
securities. The Fund will invest only in those taxable temporary investments
that are either U.S. Government securities or are rated within the two highest
grade grades by Moody's or, S&P or Fitch, and mature within one year from the
date of purchase or carry a variable or floating rate of interest. See the
Statement of Additional Information for further information about the temporary
investments in which the Fund may invest.

time depending on market conditions in order to help limit the Fund's exposure
to market risk. As a result, the Fund's portfolio at any given time may include
both long-term and intermediate-term Municipal Obligations.]
 
Under ordinary circumstances, the Fund will invest substantially all (at least
80%) of its net assets in its respective state's Municipal Obligations, and not
more than 20% of its net assets in "temporary investments," described below,
provided that temporary investments subject to regular federal income tax [and
AMT Bonds] may not comprise more than 20% of the Fund's net assets. For
defensive purposes, however, in order to limit the exposure of its portfolio to
market risk from temporary imbalances of supply and demand or other temporary
circumstances affecting the municipal market, the Fund may invest without limit
in temporary investments. The Fund will not be in a position to achieve its
investment objective of tax-exempt income to the extent it invests in taxable
temporary investments.

ANNEX D
 
CONSIDERATIONS RELATING TO FINANCIAL FUTURES AND OPTION CONTRACTS
 
The Fund may purchase and sell financial futures contracts, options on financial
futures or related options for the purpose of hedging its portfolio securities
against declines in the value of such securities, and to hedge against increases
in the cost of securities the Fund intends to purchase. To accomplish such
hedging, the Fund may take an investment position in a futures contract or in an
option which is expected to move in the opposite direction from the position
being hedged. Futures or options utilized for hedging purposes would either be
based on an index of long-term Municipal Obligations (i.e., those with remaining
maturities averaging 15-30 years) or relate to debt securities whose prices are
anticipated by Nuveen Advisory to correlate with the prices of the Municipal
Obligations owned by the Fund. The sale of financial futures or the purchase of
put options on financial futures or on debt securities or indexes is a means of
hedging against the risk that the value of securities owned by the Fund may
decline on account of an increase in interest rates, and the purchase of
financial futures or of call options on financial futures or on debt securities
or indexes is a means of hedging against increases in the cost of the securities
the Fund intends to purchase as a result of a decline in interest rates. Writing
a call option on a futures contract or on debt securities or indexes may serve
as a hedge against a modest decline in prices of Municipal Obligations held in
the Fund's portfolio, and writing a put option on a futures contract or on debt
securities or indexes may serve as a partial hedge against an increase in the
value of Municipal Obligations the Fund intends to acquire. The writing of such
options provides a hedge to the extent of the premium received in the writing
transaction. Regulations of the Commodity Futures Trading Commission ("CFTC")
applicable to the Fund require that transactions in futures and options on
futures be engaged in only for bona-fide hedging purposes, or if the aggregate
initial margin deposits and premiums paid by that Fund do not exceed 5% of the
market value of the Fund's assets. The Fund will not purchase futures unless it
has segregated cash, government securities or high grade liquid debt equal to
the contract price of the futures less any margin on deposit, or unless the long
futures position is covered by the sale of a put option. The Fund will not sell
futures unless the Fund owns the instruments underlying the futures or owns
options on such instruments or owns a portfolio whose market price may be
expected to move in tandem with the market price of the instruments or index
underlying the futures. In addition, the Fund is subject to the tax requirement
that less than 30% of its gross income may be derived from the sale or
disposition of securities held for less than three months. With respect to its
engaging in transactions involving the purchase or writing of put and call
options on debt securities or indexes, the Fund will not purchase such options
if more than 5% of its assets would be invested in the premiums for such
options, and it will only write "covered" or "secured" options, wherein the
securities or cash required to be delivered upon exercise are held by the Fund,
with such cash being maintained in a segregated account. These requirements and
limitations may limit the Fund's ability to engage in hedging transactions.
 
Description of Financial Futures and Options. A futures contract is a contract
between a seller and a buyer for the sale and purchase of specified property at
a specified future date for a specified price. An option is a contract that
gives the holder of the option the right, but not the obligation, to buy (in the
case of a call option) specified property from, or to sell (in the case of a put
option) specified property to, the writer of the option for a specified price
during a specified period prior to the option's expiration. Financial futures
contracts and options cover specified debt securities (such as U.S. Treasury
securities) or indexes designed to correlate with price movements in certain
categories of debt securities. At least one exchange trades futures contracts on
an index designed to correlate with the long-term municipal bond market.
Financial futures contracts and options on financial futures contracts are
traded on exchanges regulated by the CFTC. Options on certain financial
instruments and financial indexes are traded in securities markets regulated by
the Securities and Exchange Commission. Although futures contracts and options
on specified financial instruments call for settlement by delivery of the
financial instruments covered by the contracts, in most cases positions in these
contracts are closed out in cash by entering into offsetting, liquidating or
closing transactions. Index futures and options are designed for cash settlement
only.
 
Risks of Futures and Options Transactions. There are risks associated with the
use of futures contracts and options for hedging purposes. Investment in futures
contracts and options involves the risk of imperfect correlation between
movements in the price of the futures contract and options and the price of the
security being hedged. The hedge will not be fully effective where there is
imperfect correlation between the movements in the two financial instruments.
For example, if the price of the futures contract moves more than the price of
the hedged security, a Fund will experience either a loss or gain on the future
which is not completely offset by movements in the price of the hedged
securities. Further, even where perfect correlation between the price movements
does occur, a Fund will sustain a loss at least equal to the commissions on the
financial futures transaction. To compensate for imperfect corrections, the Fund
may purchase or sell futures contracts in a greater dollar amount than the
hedged securities if the volatility of the hedged securities is historically
greater than the volatility of the futures contracts. Conversely, the Fund may
purchase or sell fewer futures contracts if the volatility of the price of the
hedged securities is historically less than that of the futures contracts.
 
Because of low initial margin deposits made upon the opening of a futures
position, futures transactions involve substantial leverage. As a result,
relatively small movements in the price of the futures contract can result in
substantial unrealized gains or losses. Because the Fund will engage in the
purchase and sale of financial futures contracts solely for hedging purposes,
however, any losses incurred in connection therewith should, if the hedging
strategy is successful, be offset in

whole or in part by increases in the value of securities held by the Fund or
decreases in the price of securities the Fund intends to acquire.
 
The Fund expects to liquidate a majority of the financial futures contracts they
enter into through offsetting transactions on the applicable contract market.
There can be no assurance, however, that a liquid secondary market will exist
for any particular futures contract at any specific time. Thus, it may not be
possible to close a futures position. In the event of adverse price movements,
the Fund would continue to be required to make daily cash payments of variation
margin. In such situations, if a Fund has insufficient cash, it may be required
to sell portfolio securities to meet daily variation margin requirements at a
time when it may be disadvantageous to do so. The inability to close out futures
positions also could have an adverse impact on the Fund's ability to hedge its
portfolio effectively and may expose the Fund to risk of loss. The Fund will
enter into a futures position only if, in the judgment of Nuveen Advisory, there
appears to be an actively traded secondary market for such futures contracts.
 
The liquidity of a secondary market in a futures contract may be adversely
affected by "daily price fluctuation limits" established by commodity exchanges
which limit the amount of fluctuation in a futures contract price during a
single trading day. Once the daily limit has been reached in the contract, no
trades may be entered into at a price beyond the limit, thus preventing the
liquidation of open futures positions. Prices have in the past moved the daily
limit on a number of consecutive trading days.
 
The successful use of transactions in futures also depends on the ability of
Nuveen Advisory to forecast the direction and extent of interest rate movements
within a given time frame. To the extent these prices remain stable during the
period in which a futures contract is held by the Fund or moves in a direction
opposite to that anticipated, the Fund may realize a loss on the hedging
transaction which is not fully or partially offset by an increase in the value
of portfolio securities. As a result, the Fund's total return for such period
may be less than if it had not engaged in the hedging transaction.
 
The ability of the Fund to engage in transactions in futures contracts may be
limited by the tax requirement that it have less than 30% of its gross income
derived from the sale or other disposition of stock or securities held for less
than three months. Gain from transactions in futures contracts will be taxable
to a Fund's shareholders partially as short-term and partially as long-term
capital gain.
