                           IMPORTANT INFORMATION FOR
                NUVEEN FLAGSHIP ALABAMA MUNICIPAL BOND FUND AND
        NUVEEN FLAGSHIP SOUTH CAROLINA MUNICIPAL BOND FUND SHAREHOLDERS
 
Your Nuveen Flagship Fund will host a Joint Special Meeting of Shareholders on
Thursday, August 13, 1998, at our headquarters in Chicago, Illinois. The purpose
is to vote on an important proposal affecting your funds.
 
The first few pages of this booklet summarize Nuveen's proposal and explain the
proxy process -- including how to cast your votes. Before you vote, please read
the full text of the proxy statement for a complete understanding of the
proposal.
 
Q. WHAT ARE SHAREHOLDERS BEING ASKED TO VOTE ON AT THE UPCOMING SPECIAL
   SHAREHOLDER MEETING ON AUGUST 13?
 
A. The Board of Trustees for the Nuveen Flagship Alabama Municipal Bond Fund
   (the "Alabama Fund") and the Nuveen Flagship South Carolina Municipal Bond
   Fund (the "South Carolina Fund") has called a Joint Special Shareholder
   Meeting for August 13, 1998 at which you will be asked to vote on a
   reorganization (the "Reorganization") of your particular fund into the Nuveen
   Flagship All-American Municipal Bond Fund (the "All-American Fund").
 
Q. ARE THERE ANY DIFFERENCES BETWEEN THE FUNDS?
 
A. The All-American Fund is substantially the same as the Alabama Fund and the
   South Carolina Fund in its philosophy, investment objectives and policies and
   day-to-day portfolio management except that the All-American Fund invests in
   municipal bonds issued nationwide and so does not invest substantially all of
   its assets in municipal bonds exempt from both regular federal as well as
   Alabama or South Carolina state income tax, respectively. In evaluating the
   Reorganization, Alabama Fund and South Carolina Fund shareholders should
   consider the impact of losing the exemption from Alabama or South Carolina
   state income tax, respectively.
 
Q. WHAT ADVANTAGES WILL THIS PRODUCE FOR FUND SHAREHOLDERS?
 
A. We expect the proposed Reorganization to (i) lower gross operating expenses
   as a percentage of net assets due to the All-American Fund's larger net
   assets and greater economies of scale; (ii) improve portfolio
   diversification; and (iii) lower portfolio transaction costs. The Board
   believes that these potential benefits, together with the potentially higher
   distributions from the All-American Fund should offset the loss of the
   exemption of the Alabama Fund's and the South Carolina Fund's dividends from
   state income tax.
 
Q. HAS THE FUND'S BOARD OF TRUSTEES APPROVED THE PROPOSAL?
 
A. The Board of Trustees of both funds has agreed unanimously that this
   Reorganization is in your best interests and recommends that you vote in
   favor of it.
 
Q. WHAT IS THE TIMETABLE FOR THE REORGANIZATION?
 
A. Effective May 8, 1998, the Alabama Fund and the South Carolina Fund were
   closed to new investors; existing investors, however, may continue to make
   additional purchases and reinvest dividends. If approved by shareholders on
   August 13, 1998, the Reorganization is expected to take effect on August 21,
   1998.
 
Q. WILL I RECEIVE NEW SHARES IN EXCHANGE FOR MY CURRENT SHARES?
 
A. Yes. Upon approval and completion of the Reorganization, you will receive
   shares equal to the same value of your current shares. Shareholders of the
   Alabama Fund and South Carolina Fund will exchange their shares for shares of
   the All-American Fund based upon a specified exchange ratio determined by the
   ratio of the respective net asset values of the funds. You will receive
   All-American Fund shares whose aggregate value at the time of issuance will
   equal the aggregate value of your Alabama Fund shares or South Carolina Fund
   shares on that date.
<PAGE>   4
 
Q. IF I OWN SHARES IN CERTIFICATE FORM, WILL I NEED TO EXCHANGE THEM FOR
   CERTIFICATES OF MY NEW FUND?
 
A. No certificates for All-American Fund shares will be issued as part of the
   Reorganization, although we will send you certificates upon request. If you
   currently own Alabama Fund or South Carolina Fund shares in certificate form,
   you will need to return these certificates to Nuveen in order to receive new
   certificates for your All-American Fund shares.
 
   If you prefer, however, you may exchange your certificates for book entry
   shares. These shares are held in a convenient computerized system that
   enables shareholders to receive a complete and accurate record of their
   holdings without having to worry about the safekeeping of certificates or the
   expense involved with replacing a lost or stolen certificate. Just complete
   the appropriate section of the Letter of Transmittal requesting book entry
   shares. Regardless of the way you choose to hold your shares, certificates
   should be returned to the fund's transfer agent by certified mail as soon as
   possible.
 
Q. WILL I HAVE TO PAY ANY FEES OR EXPENSES IN CONNECTION WITH THE
   REORGANIZATION?
 
A. No. All of the funds' expenses associated with each Reorganization will be
   borne by the Alabama Fund and the South Carolina Fund, respectively. However,
   since Nuveen currently reimburses any additional operating expenses for these
   funds, Nuveen will effectively bear the full costs of each Reorganization.
 
Q. HOW DO MANAGEMENT FEES AND OTHER FUND OPERATING EXPENSES COMPARE BETWEEN THE
   TWO FUNDS?
 
A. Upon approval and completion of the proposed Reorganization, Alabama Fund and
   South Carolina Fund shareholders will pay lower management fees as a
   percentage of net assets and will also benefit from lower gross fund
   operating expenses (before expense waivers/reimbursements) as a percentage of
   net assets, reflecting the larger net assets and greater economies of scale
   of the All-American Fund. Currently, net fund operating expenses (after
   expense waivers/ reimbursements) of the Alabama Fund and the South Carolina
   Fund are lower than those of the All-American Fund as a percentage of net
   assets, but only because of voluntary expense waivers/reimbursements by
   Nuveen. There can be no assurance over time that Nuveen will continue these
   waivers/reimbursements for the Alabama Fund or the South Carolina Fund if the
   Reorganization is not approved.
 
Q. WILL THIS REORGANIZATION CREATE A TAXABLE EVENT FOR ME?
 
A. Each Reorganization is intended to qualify as a tax-free reorganization. As a
   result, you will recognize no gain or loss for federal income tax purposes as
   a result of the Reorganization. In addition, the tax basis and holding period
   of the All-American Fund shares you receive will be the same as the tax basis
   and holding period of your Alabama Fund/South Carolina Fund shares.
 
Q. CAN I EXCHANGE OR REDEEM MY ALABAMA FUND OR SOUTH CAROLINA FUND SHARES BEFORE
   THE REORGANIZATION TAKES PLACE?
 
A. You may exchange your Alabama Fund shares or South Carolina Fund shares for
   shares of any other Nuveen Mutual Fund, or redeem your shares, at any time.
   If you choose to do so, your request will be treated as a normal exchange or
   redemption of shares (subject to any applicable deferred sales charge) and
   will be a taxable transaction for federal income tax purposes.
 
Q. HOW DO I VOTE MY SHARES?
 
A. You can vote your shares by completing and signing the enclosed proxy
   card(s), and mailing them in the enclosed postage-paid envelope. If you need
   any assistance, or have any questions regarding the proposals or how to vote
   your shares, please call your financial adviser or Nuveen at (800) 257-8787
   weekdays from 7:00 a.m. to 7:00 p.m. Central time.
 
Q. WILL NUVEEN CONTACT ME?
 
A. You may receive a call to verify that you received your proxy materials and
   to answer any questions you may have about the Reorganization.

DEAR NUVEEN FUNDS SHAREHOLDER:
 
Enclosed is a proxy asking you to vote on the reorganization of your Fund into
the Nuveen Flagship All-American Municipal Bond Fund, a mutual fund that pursues
a similar investment objective. Subject to shareholder approval, you would
become a shareholder of the All-American Fund.
 
The enclosed Joint Prospectus/Proxy Statement contains information you will need
to make an informed decision. For your convenience, we also have provided a
brief question and answer section, which we hope you will find useful as you
review your materials before voting. For more detailed information about the
reorganization, please refer to the Joint Prospectus/ Proxy Statement.
 
The proposal has been approved by the Trustees for your Fund, who recommend you
vote "FOR" the proposal. Please give this matter your prompt attention. We will
need to receive your proxy card before the shareholder meeting scheduled for
August 13, 1998. YOUR IMMEDIATE RESPONSE WILL HELP SAVE ON THE COSTS OF
ADDITIONAL SOLICITATIONS. We look forward to your participation, and we thank
you for your continued confidence in Nuveen.

NUVEEN FLAGSHIP ALL-AMERICAN MUNICIPAL BOND FUND
RELATING TO THE ACQUISITION OF ASSETS AND LIABILITIES OF
NUVEEN FLAGSHIP ALABAMA MUNICIPAL BOND FUND AND
NUVEEN FLAGSHIP SOUTH CAROLINA MUNICIPAL BOND FUND
 
This Joint Prospectus/Proxy Statement is being furnished to shareholders of the
Nuveen Flagship Alabama Municipal Bond Fund (the "Alabama Fund") and the Nuveen
Flagship South Carolina Municipal Bond Fund (the "South Carolina Fund") (both
the Alabama Fund and the South Carolina Fund are sometimes referred to as a
"Fund" or collectively as the "Funds" or the "State Funds"), each a series of
the Nuveen Flagship Multistate Trust III (the "Multistate Trust" or a "Trust"),
a Massachusetts business trust, and relates to the special meeting of
shareholders of the State Funds to be held in the 31st floor conference room of
John Nuveen & Co., Incorporated, 333 West Wacker Drive, in Chicago on Thursday,
August 13, 1998 at 10:00 a.m., Central Time and at any and all adjournments
thereof (the "Special Meeting"). Shareholders of record as of the close of
business on June 16, 1998 are entitled to vote at the Special Meeting or any
adjournment thereof. For the Alabama Fund, the primary purpose of the Special
Meeting is to approve or disapprove the proposed reorganization of the Alabama
Fund into the Nuveen Flagship All-American Municipal Bond Fund (the
"All-American Fund," which may also sometimes be referred to as a "Fund") and
for the South Carolina Fund, the primary purpose of the Special Meeting is to
approve or disapprove the proposed reorganization of the South Carolina Fund
into the All-American Fund (each reorganization may be referred to as a
"Reorganization"). Each Reorganization would result in shareholders of the State
Funds in effect exchanging their Class A, B, C and R shares of such Funds for
corresponding Class A, B, C and R shares of the All-American Fund. The purpose
of the Reorganizations is to permit the shareholders of the State Funds to (i)
achieve certain economies of scale from the All-American Fund's larger net asset
size and the potentially lower operating expenses associated therewith, and (ii)
obtain greater portfolio diversity and potentially lower portfolio transaction
costs.
 
The All-American Fund is a series of the Nuveen Flagship Municipal Trust, an
open-end management investment company organized as a Massachusetts business
trust (the "Municipal Trust" or a "Trust"). The investment objective of the All-
American Fund is to provide as high a level of current interest income exempt
from regular federal income taxes as is consistent with preservation of capital.
There can be no assurance that the All-American Fund will achieve its investment
objective. The address, principal executive office and telephone number of the
Funds is 333 West Wacker Drive, Chicago, Illinois 60606, (312) 917-7700 or (800)
414-7447. The enclosed proxy and this Joint Prospectus/Proxy Statement are first
being sent to shareholders of the State Funds on or about June 29, 1998.
                            ------------------------
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE REGULATORS, NOR HAS THE SECURITIES AND EXCHANGE
COMMISSION OR ANY STATE REGULATORS PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
JOINT PROSPECTUS/PROXY STATEMENT. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.
 
This Joint Prospectus/Proxy Statement sets forth concisely the information
shareholders of the Alabama and South Carolina Funds should know before voting
on the respective Reorganizations (in effect, investing in Class A, B, C or R
shares of the All-American Fund) and constitutes an offering of Class A, B, C or
R shares of beneficial interest, par value $.01 per share, of the All-American
Fund only. Please read it carefully and retain it for future reference. A
Statement of Additional Information dated             , 1998, relating to this
Joint Prospectus/Proxy Statement (the "Reorganization SAI") has been filed with
the Securities and Exchange Commission (the "SEC") and is incorporated herein by

Additional Information containing additional information about the All-American
Fund, each dated August 27, 1997, have been filed with the SEC and are

A. SUMMARY
 
The following is a summary of, and is qualified by reference to, the more
complete information contained in this Joint Prospectus/Proxy Statement and the
information attached hereto or incorporated herein by reference (including the
Agreement and Plan of Reorganization). As discussed more fully below and
elsewhere in this Joint Prospectus/Proxy Statement, the Board of Trustees of the
Multistate Trust (the "Board") believes each proposed Reorganization (as defined
herein) is in the best interests of shareholders of the Alabama and South
Carolina Funds, respectively, and would not result in dilution of shareholders'
interest. As a result of the Reorganizations, shareholders of the Alabama and
South Carolina Funds would acquire an interest in the All-American Fund.
 
Shareholders should read the entire Joint Prospectus/Proxy Statement carefully
together with the All-American Fund Prospectus incorporated herein by reference
and accompanying this Joint Prospectus/Proxy Statement. This Joint
Prospectus/Proxy Statement constitutes an offering of Class A, B, C and R shares
of the All-American Fund only.
 
THE REORGANIZATIONS
 
This Joint Prospectus/Proxy Statement is being furnished to shareholders of the
Alabama and South Carolina Funds in connection with the proposed combination of
each Fund with and into the All-American Fund pursuant to the terms and
conditions of the Agreement and Plan of Reorganization dated April 25, 1998
between the State Funds and the All-American Fund (the "Agreement"). The
Agreement provides that each State Fund would (i) transfer all of its assets to
the All-American Fund in exchange solely for Class A, B, C and R shares of the
All-American Fund and the All-American Fund's assumption of the liabilities of
the Fund, (ii) distribute to each shareholder of the Fund shares of the
respective class of shares of the All-American Fund equal in value to their
existing shares of the Fund as a distribution in liquidation of the Fund, and
(iii) be liquidated, dissolved and terminated as a series of the Multistate
Trust in accordance with the Trust's Declaration of Trust promptly following the
Closing (as defined herein) (each a "Reorganization," collectively, the
"Reorganizations").
 
The Board of Trustees of the Multistate Trust has determined that the
Reorganizations are in the best interests of the Alabama and South Carolina
Funds and that the interests of existing shareholders of the Funds will not be
diluted as a result of the Reorganizations. The Board of the Multistate Trust
unanimously approved the Reorganizations and the Agreement on April 25, 1998.
 
Each State Fund will pay all of the Funds' costs associated with its respective
Reorganization. However, since the investment adviser currently waives and/or
reimburses certain operating expenses for the State Funds, the Adviser will
effectively bear the full cost of the Reorganizations.
 
The Board is asking shareholders of both the Alabama and South Carolina Funds to
approve the Reorganizations at the Special Meeting to be held on August 13,
1998. If shareholders of the Alabama and/or South Carolina Funds approve their
respective Reorganization, it is expected that the Closing of such
Reorganization will be after the close of business on August 21, 1998, but it
may be at a different time as described herein. The Reorganization for each of
the Alabama and South Carolina Funds is not contingent upon approval of the
other Fund's shareholders.
 
THE BOARD RECOMMENDS THAT YOU VOTE "FOR" THE REORGANIZATIONS. FOR EACH OF THE
ALABAMA AND SOUTH CAROLINA FUNDS, APPROVAL OF THE REORGANIZATION REQUIRES THE
FAVORABLE VOTE OF THE HOLDERS OF A MAJORITY OF THE OUTSTANDING SHARES ENTITLED
TO VOTE OF THAT PARTICULAR FUND. SEE "VOTING INFORMATION AND REQUIREMENTS"
BELOW.
 
REASONS FOR THE PROPOSED REORGANIZATIONS
 
The Board believes that the proposed Reorganizations would be in the best
interests of the Alabama and South Carolina Funds because it would permit the
shareholders of those Funds to (i) achieve certain economies of scale from the
All-American Fund's larger net asset size and the potentially lower operating
expenses associated therewith, and (ii) obtain greater portfolio diversity and
potentially lower portfolio transaction costs.
 
In determining whether to recommend approval of the Reorganizations to
shareholders of the Alabama and South Carolina Funds, the Board considered a
number of factors, including, but not limited to: (i) the capabilities and
resources of the Adviser and other service providers to the All-American Fund in
the areas of marketing, investment and shareholder services; (ii) the expenses
and advisory fees applicable to the State Funds and the All-American Fund before
the Reorganizations and the estimated expense ratios of the All-American Fund
after the Reorganizations; (iii) the investment performance of the Alabama and
South Carolina Funds compared to the All-American Fund; (iv) the terms and
conditions of the Agreement and whether the Reorganizations would result in
dilution of the Alabama or South Carolina Funds' shareholder interests; (v) the
economies of scale potentially realized through the combination of the Funds;
(vi) the compatibility of the Funds' investment objectives; (vii) the
compatibility of the Funds' service features available to shareholders,
including the retention of applicable holding periods and exchange privileges;
(viii) the costs estimated to be incurred by the respective Funds as a result of
the Reorganizations; (ix) the future growth prospects of the Alabama and South
Carolina Funds; and (x) the
 
 1
<PAGE>   11
 
anticipated tax consequences of the Reorganizations including differences in
state tax treatment of the Alabama and South Carolina Funds distributions
compared with the All-American Fund.
 
In this regard, the Board reviewed information provided by the Adviser relating
to the anticipated impact on the shareholders of the Alabama and South Carolina
Funds as a result of the Reorganizations. The Board considered the probability
that the increase in asset levels of the combined fund after the Reorganizations
would result in the following potential benefits for shareholders of the Alabama
and South Carolina Funds, although there can, of course, be no assurances in
this regard:
 
1. Achievement of Economies of Scale and Reduced Per Share Expenses. Combining
   the net assets of each of the Alabama and South Carolina Funds with the
   assets of the All-American Fund should lead to reduced total operating
   expenses for shareholders of the Alabama and South Carolina Funds,
   respectively, on a per share basis, by allowing fixed and relatively fixed
   costs, such as accounting, legal and printing expenses, to be spread over a
   larger asset base. The All-American Fund also pays lower investment advisory
   fees than either the Alabama or South Carolina Funds when no expense waivers
   or reimbursements are in effect. Any reductions in expenses on a per share
   basis should, in turn, increase portfolio net income available for
   distributions to shareholders of the Alabama and South Carolina Funds. The
   advisory fees and other operating expenses of either the Alabama or South
   Carolina Funds are currently less than those of the All-American Fund but
   only because of voluntary fee and expense waivers or reimbursements from the
   Adviser. There can be no assurance that such waivers or reimbursements will
   continue for either the Alabama or South Carolina Funds if the
   Reorganizations are not completed.
 
2. Benefits to the Portfolio Management Process. The larger net asset size of
   the All-American Fund generally permits it to purchase larger individual
   portfolio investments that may result in reduced transaction costs or more
   favorable pricing and provide the opportunity for greater portfolio
   diversity. A larger, more diverse fund may also be able to produce a more
   stable and consistent dividend rate than a smaller, less diverse fund.
 
Based upon these and other factors, the Board unanimously determined that the
Reorganizations are in the best interests of the Alabama and South Carolina
Funds.
 
COMPARISON OF THE ALL-AMERICAN FUND WITH THE STATE FUNDS
 
INVESTMENT OBJECTIVES. The All-American Fund and the State Funds have similar
investment objectives. The investment objective of the All-American Fund is to
provide as high a level of current interest income exempt from regular federal
income taxes as is consistent with preservation of capital. The investment
objective of the State Funds is to provide as high a level of current interest
income exempt from regular federal, state and, in some cases, local income taxes
as is consistent with preservation of capital. The primary difference between
the investment objectives of the State Funds and the All-American Fund is that
each State Fund seeks income exempt from Alabama and South Carolina personal or
corporate income tax, respectively, but the All-American Fund does not. The
Board, however, believes that the benefits to both the Alabama and South
Carolina Funds' shareholders from the Reorganizations, including the potentially
lower operating costs and potentially higher distributions from the All-American
Fund relative to both the Alabama and South Carolina Funds, should offset the
loss of the exemption from the state personal income tax. In evaluating the
Reorganizations, the Alabama and South Carolina Funds' shareholders should
consider the impact of losing the exemption from Alabama and South Carolina
personal income taxes on distributions made by the State Funds. Shareholders
should consult their own tax advisers to determine the specific tax consequences
of all transactions relating to the Reorganizations.
 
INVESTMENT POLICIES. The All-American Fund and the State Funds have similar
investment policies. The All-American Fund invests primarily in municipal bonds
that pay interest that is exempt from regular federal income taxes. The State
Funds invest substantially all of their assets (at least 80%) in municipal bonds
that pay interest that is exempt from regular federal, state, and in some cases,
local income taxes. The All-American Fund and the State Funds purchase only
quality municipal bonds that either are rated investment grade (AAA/Aaa to
BBB/Baa) by independent ratings agencies at the time of purchase or are
non-rated but judged to be investment grade by the Adviser, except that the
Funds may not invest more than 20% of their net assets in unrated bonds. Bond
ratings are furnished by Standard & Poor's Corporation ("S&P") and Moody's
Investor Services ("Moody's"). According to published guidelines, securities
rated BBB by S&P are regarded by S&P as having an adequate capacity to pay
interest and repay principal. Whereas such securities normally exhibit adequate
protection parameters, adverse economic conditions or changing circumstances are
more likely, in the opinion of S&P, to lead to a weakened capacity to pay
interest and repay principal for debt in this category than in higher rated
categories. According to published guidelines, securities rated Baa by Moody's
are considered by Moody's as medium grade obligations. Such securities are, in
the opinion of Moody's, neither highly protected nor poorly secured. Interest
payments and principal security appear to Moody's to be adequate for the present
but certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. In the opinion of Moody's they lack
outstanding investment characteristics and in fact have speculative
characteristics as well.
 
The State Funds and the All-American Fund have substantially the same investment
policies except that the Alabama and South Carolina Funds generally invest at
least 80% of their total assets in Alabama and South Carolina municipal
securities,
 
 2
<PAGE>   12
 
respectively, and the All-American Fund generally does not invest more than 25%
of its total assets in securities of issuers located in any one state.
 
Also, the State Funds and the All-American Fund have different policies with
respect to diversification. The State Funds are non-diversified funds. The
All-American Fund is a diversified fund and may not invest more than 5% of its
net assets in securities of any one issuer (except U.S. government securities or
for 25% of its net assets). A non-diversified fund such as the State Funds may
invest a higher percentage of their assets in relatively fewer issuers than a
diversified fund such as the All-American Fund.
 
Credit Quality. A comparison of the credit qualities of the respective
portfolios of the All-American Fund and the State Funds, as of April 30, 1998,
is set forth in the table below.

As of April 30, 1998, each State Fund was invested in more higher-rated
securities than the All-American Fund. Generally, on April 30, 1998, the average
portfolio credit quality was AA/Aa for the State Funds and A/A for the
All-American Fund. As discussed above, higher-rated securities generally have
less credit risk than lower rated securities.

</TABLE>
 
(1) Class A share returns are actual. Class B, C and R share returns are actual
for the period since inception; returns prior to class inception are Class A
share returns adjusted for differences in sales charges and expenses, which are
primarily differences in distribution and service fees. Class A Shares have a
4.2% maximum up-front sales charge which is reflected in the return figures.
Class B shares have a contingent deferred sales charge (CDSC) that begins at 5%
for redemptions during the first year after purchase and declines periodically
to 0% over the following five years, which is reflected in the return figures.
Class B shares convert automatically to Class A shares eight years after
purchase. Class C shares have a 1% CDSC for redemptions within one year which is
reflected in the year-to-date total return. Total returns assume reinvestment of
all dividends and distributions.
 
The following table is a comparison of the yields of the respective portfolios
of the All-American Fund and the State Funds as of April 30, 1998.

The total returns, yields and distribution rates are not necessarily indicative
of future results. The performance of an investment company is the result of
conditions in the securities markets, portfolio management and operating
expenses. Although information such as that shown above is useful in reviewing a
fund's performance and in providing some basis for comparison with other
investment alternatives, it should not be used for comparison with other
investments using different reinvestment assumptions or time periods. In the
absence of expense reimbursements for the State Funds, each State Fund's total
returns and yields would have been reduced.
 
Management's discussion of the All-American Fund's performance as of October 31
and April 30, 1997 is attached hereto as Exhibit A. Management's discussion of
the Alabama and South Carolina Funds' performance as of November 31 and May 31,
1997 are attached hereto as Exhibit B and Exhibit C, respectively.
 
Investment Adviser. The All-American Fund and the State Funds are managed by the
Adviser. The Adviser is a wholly owned subsidiary of John Nuveen & Co.
Incorporated ("Nuveen"), the Funds' principal underwriter. In 1961, Nuveen began
sponsoring the Nuveen Tax-Exempt Unit Trust and since that time has issued more
than $37 billion in taxable and tax-exempt unit trusts, including over $12
billion in tax-exempt insured unit trusts. In addition, Nuveen open-end and
closed-end funds held approximately $36 billion in securities under management
as of the date of the Joint Prospectus/Proxy Statement. Over 1,000,000
individuals have invested to date in Nuveen's funds and trusts. Founded in 1898,
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 in St. Paul, Minnesota and is principally engaged in providing
property liability insurance through subsidiaries. The Adviser's principal
office is located at 333 West Wacker Drive, Chicago, Illinois 60606.
 
Advisory and Other Fees. The contractual advisory fees and total operating
expenses of the All-American Fund are lower than those of either State Fund.
Pursuant to an investment management agreement between the Adviser and the
Municipal Trust, the All-American Fund pays the Adviser an annual management fee
at the rates set forth below:

For assets over $2 billion              .4250 of 1%
- ---------------------------------------------------
</TABLE>
 
For the fiscal year ended April 30, 1997, the All-American Fund paid the Adviser
$1,429,246. No expense reimbursements were in effect with respect to the
All-American Fund at such time. For a complete description of the All-American
Fund's advisory services, see the All-American Fund Summary in the All-American
Fund Prospectus and the sections of the All-American Fund Prospectus and
Statement of Additional Information entitled "Fund Service
Providers -- Investment Adviser" and "Investment Adviser and Investment
Management Agreement," respectively.
 
Pursuant to an investment management agreement between the Adviser and the
Multistate Trust, each State Fund pays the Adviser an annual management fee at
the rates set forth below:

For the fiscal year ended May 31, 1997, the Alabama Fund paid the Adviser $0
(after expense reimbursement) and would have paid $40,714 (assuming no expense
reimbursement) and the South Carolina Fund paid the Adviser $0 (after expense
reimbursement) and would have paid $69,232 (assuming no expense reimbursement).
For a complete description of the advisory services provided to each State Fund,
see the Alabama and South Carolina Funds' Summaries in the State Funds
Prospectus and the sections of the State Funds Prospectus and Statement of
Additional Information entitled "Fund Service Providers -- Investment Adviser"
and "Investment Adviser and Investment Management Agreement," respectively.
 
The advisory fees and other operating expenses of the Alabama and South Carolina
Funds are currently less than those of the All-American Fund but only because of
voluntary expense waivers or reimbursements from the Adviser. There can be no
assurance that such waivers or reimbursements will continue for either State
Fund if the Reorganizations are not completed.
 
The All-American Fund and the State Funds have adopted substantially the same
distribution and service plans (the "Distribution and Service Plans") pursuant
to Rule 12b-1 under the 1940 Act. The Distribution and Service Plans authorize
each Fund to pay Nuveen an annual 0.20% service fee on the average daily net
assets of Class A, B and C shares outstanding. The plans also authorize each
Fund to pay Nuveen an annual 0.75% distribution fee on the average daily net
 
 5
<PAGE>   15
 
assets of Class B shares outstanding. The plans also authorize each Fund to pay
Nuveen an annual 0.55% distribution fee on the average daily net assets of Class
C shares outstanding. In order to help compensate Nuveen for the sales
commissions paid to financial advisers at the time of sale on sales of Class B
and Class C shares, Nuveen retains the first year's service fee on sales of
Class B shares and all Class B distribution fees, and retains the first year's
service and distribution fees on sales of Class C shares. Otherwise, Nuveen pays
these fees to the broker of the record. The distributor of the State Funds'
shares and the All-American Fund's shares is Nuveen. For a complete description
of these arrangements with respect to the All-American Fund and the State Funds,
see the section of the All-American Fund and State Funds Prospectuses and
Statements of Additional Information entitled "Service Providers -- The
Distributor" and "The Distribution and Service Plans," respectively.
 
The tables below set forth (i) the fees and expenses paid by the All-American
Fund and the Alabama and South Carolina Funds for their last fiscal year, which
was April 30, 1998 for the All-American Fund and May 31, 1998 for the Alabama
and South Carolina Funds and (ii) pro forma expenses for the combined fund for
Class A, B, C and R shares. The pro forma expenses reflect the impact of both
the Alabama and South Carolina Funds.

(1) Nuveen pays authorized dealers a commission equal to the sum of 1% of the
    first $2.5 million, plus 0.50% of the next $2.5 million, plus 0.25% of any
    amount over $5 million. Unless the authorized dealer waived the commission,
    you may be assessed a contingent deferred sales charge (CDSC) of 1% if you
    redeem any of your shares within 18 months of purchase. The CDSC is
    calculated on the lower of your purchase price or redemption proceeds.
 
The initial sales charge applicable to Class A shares of the All-American Fund
will be waived for Class A shares acquired in the Reorganizations. Any
subsequent purchases of Class A shares of the All-American Fund after the
Reorganizations will be subject to the initial sales charge, excluding Class A
shares purchased through the dividend reinvestment plan.
 
The Class B shares of the All-American Fund and the State Funds do not incur a
sales charge when they are purchased, but generally are subject to a .20% annual
service fee and a .75% annual distribution fee. Class B Shares are also subject
to a
 
 8
<PAGE>   18
 
contingent deferred sales charge ("CDSC") if redeemed within six years after
purchase. The CDSC is calculated on the lower of the purchase price or
redemption proceeds.

Class B shares of both the All-American Fund and the State Funds convert
automatically to Class A shares eight years after purchase. Class B shares will
convert only if the Fund is assured that the conversion does not generate tax
consequences for investors, based upon the opinion of outside counsel or the
written assurance of the IRS.
 
The Class C shares of the All-American Fund and the State Funds do not incur a
sales charge when purchased, but are subject to a .20% annual service fee and a
 .55% annual distribution fee. Class C shares are also subject to a CDSC of 1.00%
if redeemed within the first year after purchase.
 
Class R shares of the All-American Fund and the State Funds have no sales
charges or ongoing fees. For a complete description of the Class A, B, C and R
shares, see the section of either the All-American Fund or the State Funds
Prospectus and Statement of Additional Information entitled "Investing in the
Funds -- How to Select a Purchase Option" and "Additional Information on the
Purchase and Redemption of Fund Shares," respectively.
 
No contingent deferred sales charge will be imposed on Class B shares or Class C
shares of the State Funds in connection with the Reorganizations. The holding
period and conversion period for Class B shares or Class C shares of the
All-American Fund received in connection with the Reorganizations will be
measured from the earlier of the time (i) the holder purchased such shares from
the Alabama or South Carolina Funds or (ii) the holder purchased such shares
from any other Nuveen national or state fund and subsequently exchanged them for
shares of the Alabama or South Carolina Funds.
 
Shares of the All-American Fund and the State Funds may be purchased through a
financial adviser, by check, by electronic transfer, and by exchange from
certain other open-end mutual funds distributed by Nuveen. For a complete
description regarding purchase of shares and exchange of shares of the
All-American Fund and the State Funds, see the sections of the All-American Fund
and the State Funds Prospectuses and Statements of Additional Information
entitled "Investing in the Funds" and "Additional Information on the Purchase
and Redemption of Fund Shares," respectively.
 
Shares of the All-American Fund and the State Funds properly presented for
redemption may be redeemed or exchanged at the next determined net asset value
per share (subject to any applicable deferred sales charge). Shares of either
the All-American Fund or the State Funds may be redeemed or exchanged through a
financial adviser by mail or by special redemption privileges (telephone
exchange, telephone redemption, by check or by electronic transfer). If any
shares of the All-American Fund or the State Funds were purchased less than 15
days prior to your request, the Funds do not mail the redemption proceeds until
the check for the purchase has cleared, which can take up to 15 days. In
addition, the All-American Fund and the State Funds may suspend redemptions or
delay payment on redemptions for more than seven days (three days for street
name accounts) in certain extraordinary circumstances as described in the
All-American Fund and the State Funds Statements of Additional Information. In
order to limit excessive exchange activity and in other circumstances where the
Adviser believes doing so would be in the best interests of a Fund, the
All-American Fund and the State Funds reserve the right to revise or terminate
the exchange privilege, limit the amount or number of exchanges, or reject any
exchange. Shareholders are notified in the event this happens to the extent
required by law.
 
No further purchases of the shares of either the Alabama or the South Carolina
Fund may be made after the date on which the shareholders of the Alabama and/or
South Carolina Funds approve the Reorganizations, and the stock transfer books
of the Alabama and South Carolina Funds will be permanently closed as of the
date of Closing. Only redemption requests and transfer instructions received in
proper form by the close of business on the day prior to the date of Closing
will be fulfilled by the Alabama and South Carolina Funds. Redemption requests
or transfer instructions received by the Alabama and South Carolina Funds after
that date will be treated by each such Fund as requests for the redemption or
instructions for transfer of the shares of the All-American Fund credited to the
accounts of the shareholders of the Alabama and South Carolina Funds,
respectively. Redemption requests or transfer instructions received by the
Alabama and South Carolina Funds after the close of business on the day prior to
the date of Closing will be forwarded to the All-American Fund. For a complete
description of the redemption arrangements for the Funds, see the section of the
All-American Fund and State Funds Prospectus entitled "Investing in the
Funds -- How to Sell Fund Shares."
 
Capitalization. The following table sets forth the capitalization of the
All-American Fund and the State Funds as of April 30, 1998, and the pro forma
capitalization of the combined fund as if the Reorganizations had occurred on
that date. The pro

forma figures assume that both State Funds are reorganized into the All-American
Fund. These numbers may differ at the time of Closing.

B.  RISK FACTORS
 
SIMILARITY OF RISKS
 
The investment objectives of the All-American Fund and the State Funds are
substantially the same. The investment policies of the All-American Fund and the
State Funds are substantially the same insofar as they may purchase only quality
municipal bonds that are either rated investment grade (AAA/Aaa to BBB/Baa) by
independent rating agencies at the time of purchase or are non-rated but judged
to be investment grade by the Adviser. If suitable municipal bonds from a
specific state are not available at attractive prices and yields, the Funds may
invest in municipal bonds of U.S. territories (such as Puerto Rico and Guam)
which are exempt from regular federal, state, and local income taxes. The Funds
may also purchase municipal bonds that represent lease obligations. These carry
special risks because the issuer of the bonds may not be obligated to
appropriate money annually to make payments under the lease. In order to reduce
this risk, the Funds may only purchase leases where the issuer has a strong
incentive to continue making appropriations until maturity. The All-American
Fund and the State Funds also engage in certain common investment practices such
as the purchase and sale of securities on a "when-issued" and "delayed delivery"
basis. In addition, the Funds may periodically engage in hedging transactions as
described in the sections of the All-American Fund and the State Funds'
Statements of Additional Information entitled "Investment Policies and
Investment Portfolio -- Hedging and Other Defensive Actions." To the extent that
the investment objectives and investment policies and practices of the
All-American Fund and the State Funds are substantially the same, the risks
associated with an investment in the funds are substantially the same.
 
Investment in either the All-American Fund or either State Fund may not be
appropriate for all investors. None of the funds are intended to be a complete
investment program, and investors should consider their long-term investment
goals and financial needs when making an investment decision with respect to the
Funds. An investment in any of the Funds is intended to be a long-term
investment and should not be used as a trading vehicle.
 
The All-American Fund and both State Funds may invest a substantial portion of
their assets in securities that are subject to the federal alternative minimum
tax. As with both State Funds, the All-American Fund may not be a suitable
investment for shareholders subject to the alternative minimum tax.
 
DIFFERENCES IN RISKS
 
The All-American Fund and the State Funds engage in certain investment practices
that differ. To the extent that the investment practices of the Funds differ,
the risks associated with an investment in the All-American Fund are different
from the risks associated with an investment in either State Fund. An investment
in the All-American Fund may not be appropriate for all Alabama or South
Carolina Funds' shareholders. For a complete description of the risks of an
investment in the All-American Fund or the State Funds, see the sections in the
All-American Fund Prospectus or the State Funds Prospectus entitled "Fund
Strategies."
 
Diversification. The State Funds are non-diversified funds. The All-American
Fund is a diversified fund. Non-diversified funds, such as the State Funds,
generally are more susceptible to economic, political or regulatory events that
adversely affect an issuer in which such fund invests than a diversified fund
such as the All-American Fund. A diversified fund such as the All-American Fund,
however, is less likely to benefit from economic, political or regulatory events
that beneficially affect issuers in which it invests because it generally
invests a smaller percentage of its assets in each issuer in which it invests.
 
Concentration. The Alabama and South Carolina Funds invest at least 80% of their
total assets in Alabama and South Carolina municipal securities, respectively.
The All-American Fund does not concentrate its investments in the securities of
issuers located in any one state. A fund, such as the State Funds, that
concentrates its investments in issuers located in any one state generally is
more susceptible to economic, political or regulatory events that adversely
affect the state in which such company has concentrated its investments than an
investment company that does not concentrate its investments in any one state.
The All-American Fund, however, is less likely to benefit from economic,
political or regulatory events that beneficially affect issuers located in
Alabama or South Carolina because it does not concentrate its investments in
issuers of Alabama or South Carolina municipal securities or issuers located in
any one state. In addition, the Alabama and South Carolina Funds concentrate
their assets in Alabama and South Carolina municipal securities, respectively,
because of their investment objectives of seeking income exempt from the Alabama
and South Carolina personal income taxes. In evaluating the Reorganization,
Alabama and South Carolina Funds' shareholders should consider the impact of
losing the exemption from the Alabama and South Carolina personal income taxes
on distributions made by the Alabama and South Carolina Funds, respectively.
 
Maturity and Duration. The State Funds and the All-American Fund are long-term
funds and normally maintain a weighted average portfolio maturity of 15 to 30
years. Each of the Fund's portfolios have different maturity and duration
characteristics. Both dollar-weighted average maturity and duration reflect the
sensitivity of a Fund to interest rate fluctuations, whereby a Fund with a
longer maturity and duration reacts more strongly to interest rate changes than
a Fund with a shorter maturity and duration. The average dollar-weighted
maturity of a Fund is the dollar-weighted average of the stated maturities of
all debt instruments held by the Fund. Duration is the weighted present value of
principal and interest payments expressed in years and may more accurately
measure a Fund's sensitivity to incremental changes in interest rates
 
 11
<PAGE>   21
 
than average maturity. For example, a Fund with a duration of 5.0 years should
have half the interest rate sensitivity of a Fund with a duration of 10.0 years,
because the Fund with the shorter duration will receive payments (and can
reinvest at prevailing interest rates) twice as quickly. For a comparison of the
Funds' average portfolio maturity and duration, including pro-forma figures, see
"Comparison of the All-American Fund with the State Funds -- Maturity and
Duration" above.
 
C.  THE PROPOSED REORGANIZATIONS
 
The material features of the Agreement are summarized below. This summary does
not purport to be complete and is subject in all respects to the provisions of,
and is qualified in its entirety by reference to, the Agreement attached as
Appendix A to the Reorganization SAI, a copy of which may be obtained without
charge by calling the Funds at (800) 414-7447 and asking for the "Reorganization
SAI."
 
TERMS OF THE AGREEMENT
 
Pursuant to the Agreement, the All-American Fund series of the Municipal Trust
would acquire all of the assets and the liabilities of each of the Alabama and
South Carolina Funds series of the Multistate Trust on the date of the Closing
in consideration for Class A, B, C and R shares of the All-American Fund.
 
Subject to the Alabama and South Carolina Funds' shareholders separate approval
of the Reorganizations, the closing (the "Closing") will occur within 15
business days after the later of the receipt of all necessary regulatory
approvals and the final adjournment of the Special Meeting or such later date as
soon as practicable thereafter as the All-American Fund and the State Funds may
mutually agree. Approval of the Reorganization for each of the Alabama Fund and
the South Carolina Fund is not contingent upon approval of the other Fund's
shareholders.
 
On the date of the Closing, the Alabama and South Carolina Funds will each
transfer to the All-American Fund all of its assets and liabilities. The
All-American Fund will in turn transfer to the Alabama and South Carolina Funds
a number of its Class A, B, C and R shares equal in value to the value of the
net assets of the Fund, transferred to the All-American Fund as of the date of
the Closing, as determined in accordance with the valuation method described in
the All-American Fund's then current prospectus. In order to minimize any
potential for undesirable federal income and excise tax consequences in
connection with the Reorganizations, the All-American Fund and the State Funds
may individually distribute on or before the Closing all or substantially all of
their respective undistributed net investment income (including net capital
gains) as of such date.
 
The Alabama and South Carolina Funds expect to distribute in complete
liquidation the Class A, B, C and R shares of the All-American Fund to the
shareholders of the respective class of the Funds promptly after the Closing and
then each State Fund will be liquidated, dissolved and terminated as a series of
the Multistate Trust in accordance with the Trust's Declaration of Trust.
 
Both State Funds have separately made certain standard representations and
warranties to the All-American Fund regarding their capitalization, status and
conduct of business.
 
Unless waived in accordance with the Agreement, the obligations of the parties
to the Agreement are conditioned upon, among other things (except that the
obligations of the Alabama and South Carolina Funds are separate and distinct
and are not contingent upon each other):
 
          1. the approval of the Reorganization by shareholders of the
             applicable State Fund;
 
          2. the absence of any rule, regulation, order, injunction or
             proceeding preventing or seeking to prevent the consummation of the
             transactions contemplated by the Agreement;
 
          3. the receipt of all necessary approvals, registrations and
             exemptions under federal and state laws;
 
          4. the truth in all material respects as of the Closing of the
             representations and warranties of the parties and performance and
             compliance in all material respects with the parties' agreements,
             obligations and covenants required by the Agreement;
 
          5. the effectiveness under applicable law of the registration
             statement of the All-American Fund of which this Joint
             Prospectus/Proxy Statement forms a part and the absence of any stop
             orders under the Securities Act of 1933, as amended, pertaining
             thereto; and
 
          6. the receipt of opinions of counsel relating to, among other things,
             the tax-free nature of the Reorganization for federal income tax
             purposes.
 
The Agreement may be terminated or amended with respect to a Reorganization by
the mutual consent of the parties either before or after approval thereof by the
shareholders of the Alabama Fund or the South Carolina Fund, as the case may be,
provided that no such amendment after such approval shall be made if it would
have a material adverse affect on the interests of Fund shareholders. The
Agreement also may be terminated by the non-breaching party if there has been a
 
 12
<PAGE>   22
 
material misrepresentation, material breach of any representation or warranty,
material breach of contract or failure of any condition to Closing.
 
The Board recommends that you vote to approve the Reorganizations, as it
believes the Reorganizations are in the best interests of the Alabama and South
Carolina Funds and that the interests of both Funds' existing shareholders will
not be diluted as a result of consummation of the proposed Reorganizations.
 
DESCRIPTION OF SECURITIES TO BE ISSUED
 
Shares of Beneficial Interest. Beneficial interests in the All-American Fund
being offered hereby are represented by transferable Class A, B, C and R shares,
par value $0.01 per share. The Declaration of Trust of the Municipal Trust
permits the trustees, as they deem necessary or desirable, to create one or more
separate investment portfolios and to issue a separate series of shares for each
portfolio and, subject to compliance with the 1940 Act, to further subdivide the
shares of a series into one or more classes of shares for such portfolio.
 
Voting Rights of Shareholders. Holders of shares of the All-American Fund are
entitled to one vote per share on matters as to which they are entitled to vote;
however, separate votes generally are taken by each series on matters affecting
an individual series.
 
The All-American Fund operates as a series of the Municipal Trust, an open-end
management investment company registered with the SEC under the 1940 Act. In
addition to the specific voting rights described above, shareholders of the All-
American Fund are entitled, under current law, to vote with respect to certain
other matters, including changes in fundamental investment policies and
restrictions and the ratification of the selection of independent auditors.
Moreover, under the 1940 Act, shareholders owning not less than 10% of the
outstanding shares of the Municipal Trust may request that the respective board
of trustees call a shareholders' meeting for the purpose of voting upon the
removal of trustee(s).
 
CONTINUATION OF SHAREHOLDER ACCOUNTS AND PLANS; SHARE CERTIFICATES
 
If the Reorganizations are approved, the All-American Fund will establish an
account for each Alabama and South Carolina Funds' shareholder containing the
appropriate number of shares of the All-American Fund. The shareholder services
and shareholder programs of the All-American Fund and the State Funds are
substantially identical. Shareholders of the State Funds who are accumulating
shares of the Alabama and South Carolina Funds under the dividend reinvestment
plan, or who are receiving payment under the systematic withdrawal plan with
respect to shares of the Alabama and South Carolina Funds, will retain the same
rights and privileges after the Reorganizations in connection with the
All-American Fund Class A, B, C or R shares received in the Reorganizations
through substantially identical plans maintained by the All-American Fund. Chase
Manhattan Bank, custodian for the State Funds, serves as the custodian for the
assets of the All-American Fund.
 
Shareholders of the State Funds who currently own shares in certificate form are
asked to surrender these shares to the State Funds' transfer agent, Chase Global
Fund Services, P.O. Box 5186 Bowling Green Station, NY, NY 10275. State Fund
shareholders must submit a written request to Chase in order to receive
certificates for their All-American Fund shares. No certificates for
All-American Fund shares will be issued as part of the Reorganization except
upon request.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
The following is a general discussion of the material federal income tax
consequences of the Reorganizations to shareholders of the State Funds and
shareholders of the All-American Fund. The discussion set forth below is for
general information only and may not apply to a holder subject to special
treatment under the Internal Revenue Code of 1986, as amended (the "Code"), such
as a holder that is a bank, an insurance company, a dealer in securities, a
tax-exempt organization, a foreign person or that acquired its Class A, B, C and
R shares of the State Funds pursuant to the exercise of employee stock options
or otherwise as compensation. It is based upon the Code, legislative history,
Treasury regulations, judicial authorities, published positions of the Internal
Revenue Service (the "Service") and other relevant authorities, all as in effect
on the date hereof and all of which are subject to change or different
interpretations (possibly on a retroactive basis). This summary is limited to
shareholders who hold their Alabama and South Carolina Funds shares as capital
assets. No advance rulings have been or will be sought from the Service
regarding any matter discussed in this Joint Prospectus/Proxy Statement.
Accordingly, no assurances can be given that the Service could not successfully
challenge the intended federal income tax treatment described below.
Shareholders should consult their own tax advisers to determine the specific
federal income tax consequences of all transactions relating to the
Reorganizations, as well as the effects of state, local and foreign tax laws and
possible changes to the tax laws.
 
Each Reorganization is intended to qualify as a "reorganization" within the
meaning of Section 368(a)(1) of the Code. It is a condition to the Closing of
each Reorganization that the Trusts and the Funds receive an opinion from
Vedder, Price, Kaufman & Kammholz ("Vedder Price") substantially to the effect
that for federal income tax purposes:
 
          1. The acquisitions by the All-American Fund of the assets of the
             applicable State Fund in exchange solely for Class A, B, C and R
             shares of the All-American Fund and the assumption by the
             All-American Fund of the
 
 13
<PAGE>   23
 
liabilities of the State Fund will qualify as tax-free reorganizations within
the meaning of Section 368(a)(1)(C) of the Code.
 
          2. No gain or loss will be recognized by the State Fund or the
             All-American Fund upon the transfer to the All-American Fund of the
             assets of the State Fund in exchange solely for the Class A, B, C
             and R shares of the All-American Fund and the assumption by the
             All-American Fund of the liabilities of the State Fund.
 
          3. The All-American Fund's basis in the State Fund's assets received
             in a Reorganization will, in each instance, equal the basis of such
             assets in the hands of the State Fund immediately prior to the
             transfer, and the All-American Fund's holding period for such
             assets will, in each instance, include the period during which the
             assets were held by the State Fund.
 
          4. No gain or loss will be recognized by the shareholders of a State
             Fund upon the exchange of their shares of the State Fund for the
             Class A, B, C and R shares of the All-American Fund.
 
          5. The aggregate tax basis in the Class A, B, C and R shares of the
             All-American Fund received by the shareholders of a State Fund will
             be the same as the aggregate tax basis of the shares of the State
             Fund surrendered in exchange therefor.
 
          6. The holding period of the Class A, B, C and R shares of the
             All-American Fund received by the shareholders of a State Fund will
             include the holding period of the shares of the State Fund
             surrendered in exchange therefor provided such surrendered shares
             of the State Fund are held as capital assets by such shareholder.
 
In rendering its opinions, Vedder Price will rely upon certain representations
of the management of the All-American Fund and the State Funds and assume that
the Reorganizations will be consummated as described in the Agreement and that
redemptions of shares of the State Funds occurring prior to the Closing and
post-Closing redemptions of shares of the All-American Fund that are received in
the Reorganizations will consist solely of redemptions in the ordinary course of
business.
 
The All-American Fund intends to be taxed under the rules applicable to
regulated investment companies as defined in Section 851 of the Code, which are
the same rules currently applicable to the State Funds and their shareholders.
 
EXPENSES
 
The State Funds will pay all of the Fund's costs associated with each
Reorganization. However, since the Adviser currently waives and/or reimburses
certain operating expenses for the State Funds (which the Adviser intends to do
at least through the date of the Closing), the Adviser will effectively bear the
full cost of the Reorganizations. Management of the State Funds estimates that
expenses for each Reorganization will equal approximately $50,000. In addition,
as part of the Reorganizations, the Alabama and South Carolina Funds will
write-off the remaining unamortized organizational expenses of approximately
$20,300 and $11,800, respectively, which will be reimbursed by the Adviser, in
its capacity as the investment adviser of the State Funds.
 
The Board of the Multistate Trust has determined that the foregoing arrangement
with respect to expenses is fair and reasonable.
 
As noted above, shareholders of the State Funds may redeem their shares or
exchange their shares for shares of certain other open-end mutual funds
distributed by Nuveen at any time prior to the closing of the Reorganizations.
See "Distribution, Purchase, Valuation, Redemption and Exchange of Shares"
above. Redemptions and exchanges of shares generally are taxable transactions,
for federal income tax purposes unless your account is not subject to taxation,
such as an individual retirement account or other tax-qualified retirement plan.
Shareholders should consult with their own tax advisers regarding the federal,
state and local tax consequences of potential transactions.
 
LEGAL MATTERS
 
Certain legal matters concerning the federal income tax consequences of the
Reorganizations and issuance of Class A, B, C and R shares of the All-American
Fund will be passed on by Vedder, Price, Kaufman & Kammholz, 222 North LaSalle
Street, Chicago, Illinois 60601.

D. RECOMMENDATION OF THE BOARD
 
The Board of the Multistate Trust has unanimously approved the Agreement and has
determined that participation in the Reorganizations are in the best interests
of the Alabama and South Carolina Funds. The Board recommends voting "FOR" the
proposed Reorganizations.
 
                 PROPOSAL 2: SELECTION OF INDEPENDENT AUDITORS
 
The members of the Board who are not "interested persons" of the Multistate
Trust have unanimously selected Arthur Andersen LLP, independent public
accountants, as independent auditors, to audit the books and records of the
State Funds for the fiscal year ending May 31, 1999. On June 26, 1997, the
members of the Board who are not "interested persons" determined that it would
be in the Trust's best interests to have the same independent auditors as the
other Nuveen open-end funds and unanimously appointed Arthur Andersen as
independent auditors for the Trust for the current fiscal year ended May 31,
1998 to replace the former independent auditors effective with such appointment.
During the two most recent fiscal years ended May 31, 1997, there have been no
disagreements with the former independent auditors on any matter of accounting
principles or practices, financial statement disclosure or auditing scope of
procedure or any reportable events. The former independent auditors' report on
the financial statements for the past two years contained no adverse opinion or
disclaimer of opinion and was not qualified or modified as to uncertainty, audit
scope or accounting principles. The selection of Arthur Andersen LLP as
independent auditors of the State Funds for the fiscal year ended May 31, 1999
is being submitted to the shareholders for ratification, which requires the
affirmative vote of a majority of the shares of the Funds present and entitled
to vote on the matter. A representative of Arthur Andersen LLP is expected to be
present at the Joint Special Meeting and will be available to respond to any
appropriate questions raised at the Joint Special Meeting and to make a
statement if he or she wishes.
 
THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE
RATIFICATION OF THE SELECTION OF INDEPENDENT AUDITORS.

B. SHAREHOLDER PROPOSALS
 
As a general matter, the All-American Fund does not intend to hold future
regular annual or special meetings of its shareholders unless required by the
1940 Act. In the event that a Reorganization is not consummated, neither State
Fund intends to hold future regular annual or special meetings of its
shareholders unless required by the 1940 Act. Any shareholder who wishes to
submit proposals for consideration at a meeting of shareholders of the
All-American Fund or either State Fund should send such proposal to the
respective Fund at 333 West Wacker Drive, Chicago, Illinois 60606. To be
considered for presentation at a shareholders' meeting, rules promulgated by the
SEC require that, among other things, a shareholder's proposal must be received
at the offices of the Fund a reasonable time before a solicitation is made.
Timely submission of a proposal does not necessarily mean that such proposal
will be included.
 
                      VOTING INFORMATION AND REQUIREMENTS
 
Holders of shares of the State Funds are entitled to one vote per share on
matters as to which they are entitled to vote. The State Funds do not utilize
cumulative voting.
 
Each valid proxy given by a shareholder of the State Funds will be voted on by
the persons named in the proxy in accordance with the instructions marked
thereon and as the persons named in the proxy may determine on such other
business as may come before the Special Meeting on which shareholders are
entitled to vote. If no designation is made, the proxy will be voted on by the
persons named in the proxy as recommended by the Board "FOR" approval of the
Reorganizations and "FOR" the selection of independent auditors. 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 beneficial
owners or persons entitled to vote and (ii) the broker or nominee does not have
discretionary voting power on a particular matter) do not count as votes "FOR"
the proposals and are treated as votes "AGAINST." Thirty percent of the
outstanding shares of each Fund entitled to vote on the proposals must be
present in person or by proxy to have a quorum to conduct business at the
Special Meeting. Abstentions and broker non-votes will be deemed present for
quorum purposes.
 
Shareholders who execute proxies may revoke them at any time before they are
voted by filing with the Alabama and South Carolina Funds a written notice of
revocation, by delivering a duly executed proxy bearing a later date, or by
attending the Special Meeting and voting in person. The giving of a proxy will
not affect your right to vote in person if you attend the Special Meeting and
wish to do so.
 
It is not anticipated that any action will be asked of the shareholders of the
State Funds other than as indicated above, but if other matters are properly
brought before the Special Meeting, it is intended that the persons named in the
proxy will vote in accordance with their judgment.
 
APPROVAL OF EACH REORGANIZATION WILL REQUIRE THE FAVORABLE VOTE OF THE HOLDERS
OF A MAJORITY OF THE OUTSTANDING SHARES OF THE ALABAMA AND SOUTH CAROLINA FUNDS,
RESPECTIVELY, ENTITLED TO VOTE.
 
In the event that sufficient votes in favor of a proposal are not received by
the scheduled time of the Joint Special Meeting, the persons named in the proxy
may propose and vote in favor of one or more adjournments of the Joint Special
Meeting to permit further solicitation of proxies. If sufficient shares were
present to constitute a quorum, but insufficient votes had been cast in favor of
a proposal to approve it, proxies would be voted in favor of adjournment only if
the Board determined that adjournment and additional solicitation was reasonable
and in the best interests of the shareholders of the Alabama and South Carolina
Funds, taking into account the nature of the proposal, the percentage of the
votes actually cast, the percentage of negative votes, the nature of any further
solicitation that might be made and the information provided to shareholders
about the reasons for additional solicitation. Any such adjournment will require
the affirmative vote of the holders of a majority of the outstanding shares
voted at the session of the Joint Special Meeting to be adjourned.
 
Proxies of shareholders of the State Funds are solicited by the Board. In order
to obtain the necessary quorum at the Joint Special Meeting, additional
solicitation may be made by mail, telephone, telegraph or personal interview by
representatives of the Adviser or Nuveen, or by dealers or their
representatives. In addition, such solicitation servicing may also be provided
by D.F. King, at a cost estimated to be approximately $4,000, plus reasonable
expenses.

            MANAGEMENT'S DISCUSSION OF ALL-AMERICAN FUND PERFORMANCE
 
                                   Dear Shareholder
 
                                   It's a pleasure to report to you on the
                                   performance of your Nuveen municipal bond
                                   fund. Over the past 12 months, the fund has
                                   performed exceptionally well, rewarding
                                   investors with dependable tax-free income and
                                   attractive returns.
 
                                   The fund generated superior total returns and
                                   its Class A shares were ranked in the top ten
                                   percent of funds among its peer categories
                                   for the period by Lipper Analytical Services.
                                   For the 12 months ended October 31, 1997,
                                   Class A shares of the All-American Fund
                                   generated a total return of 10.09%. Investors
                                   also continued to enjoy strong dividends
                                   generated by the fund's portfolio of quality
                                   bonds. You will find additional details on
                                   the individual performance of the fund on
                                   pages A6 and A7.
 
                                   As 1997 draws to a close, it seems
                                   appropriate to take a moment to look back
                                   over what has been an exceptional time for
                                   the American economy, the financial
                                   markets -- and the investors in those
                                   markets. The year has been distinguished by
                                   continued economic strength, the lowest
                                   unemployment rates in more than two decades,
                                   and progress on fiscal issues, including a
                                   reduction in the federal deficit. While much
                                   of investors' attention has remained focused
                                   on the stock market, the achievements of the
                                   bond market should not be overlooked.
 
                                   During 1997, the environment for bond
                                   performance was enhanced by a substantial
                                   decline in interest rates, reflecting
                                   investors' confidence that inflation can
                                   remain near its current annual rate of 2.2%,
                                   one of the lowest levels for the Consumer
                                   Price Index in 30 years.

                                   The events of 1997 have also focused renewed
                                   attention on the need for diversification and
                                   asset allocation. Stock market volatility,
                                   especially in late October, provided a vivid
                                   illustration of the steadying effect that
                                   fixed-income investments can provide in a
                                   well-constructed investment portfolio. Nuveen
                                   mutual funds provide an excellent balance to
                                   other stock and bond investments, and their
                                   current yields make them very attractive.
 
                                   You already know you can rely on Nuveen to
                                   provide the tax-advantaged investments you
                                   need to pursue your investment goals. Your
                                   financial adviser can introduce you to a
                                   variety of other Nuveen products and services
                                   to round out your investment portfolio,
                                   including the Nuveen Growth and Income Stock
                                   Fund and two new balanced stock and bond
                                   funds. We have also expanded our private
                                   asset management capabilities through the
                                   acquisition of Rittenhouse Financial
                                   Services, a well-respected growth investment
                                   manager. We encourage you to talk with your
                                   financial adviser about ways to complement
                                   your current Nuveen investment by taking
                                   advantage of these additional products and
                                   services.
 
                                   We at Nuveen remain committed to providing
                                   you with quality investment solutions that
                                   withstand the test of time. We thank you for
                                   your confidence in us and our family of
                                   investments, and we look forward to our next

TED NEILD, MANAGING DIRECTOR OF    WHAT ECONOMIC AND MARKET FACTORS INFLUENCED
NUVEEN'S PORTFOLIO MANAGEMENT      THE PERFORMANCE OF MUNICIPAL BONDS OVER THE 
TEAM, TALKS ABOUT THE MUNICIPAL    PAST YEAR?
BOND MARKET AND OFFERS INSIGHTS    Over the past 12 months, the performance of 
INTO FACTORS THAT AFFECTED THE     the municipal bond market was influenced by 
PERFORMANCE OF THE FUND OVER THE   three major factors: the continued strength  
PAST YEAR.                         of the U.S. economy, minimal inflation (both
                                   of which are reflected in the               
                                   steady-to-declining interest rates evident  
                                   during the year), and volatility in the     
                                   equity markets. During 1997, these factors  
                                   contributed to a positive environment for   
                                   fixed-income investments, including         
                                   municipal issues.                           
                                                                               
                                   Between November 1996 and October 1997, the
                                   yield on the 30-year Treasury bond dropped
                                   from 6.68% to 6.15%, and the municipal
                                   market followed suit, as the yield on the
                                   Bond Buyer 40 declined from 5.80% to 5.40%.
                                   The spread between tax-free municipal bonds
                                   and taxable Treasury bonds remained tight,
                                   making municipal bonds very attractive. The
                                   strong total returns produced in this
                                   environment  were somewhat muted by a heavy
                                   supply of newly issued bonds that
                                   temporarily impacted bond prices. The
                                   increased supply worked to our advantage,
                                   however, as it expanded opportunities to
                                   find value in the marketplace.
 
                                   HOW HAS THIS FUND PERFORMED DURING THIS
                                   PERIOD?
                                   As Tim mentioned in his letter to
                                   shareholders, the fund performed
                                   exceptionally well, achieving excellent total
                                   returns and superior performance in
                                   comparison with its peers. The All-American
                                   Fund produced a total return of 10.09% on
                                   Class A shares, surpassing its Lipper peer
                                   group average of 8.12% by almost 200 basis
                                   points. Once again, this fund was one of the
                                   top performers in its category, ranking
                                   eighth among the 231 national

                                   municipal bond funds in the grouping. The
                                   fund was also rated well on a risk-adjusted
                                   basis, as evidenced by the Class A share's
                                   four-star ratings by Morningstar.
 
                                   WHAT ARE YOUR KEY STRATEGIES FOR THE COMING
                                   YEAR?
                                   To sustain such outstanding performance, we
                                   take a holistic approach to portfolio
                                   management -- assessing all of the factors
                                   that determine a fund's performance and
                                   taking advantage of all of them to contribute
                                   to total return and dividend stability. One
                                   focus in the coming year will be to maintain
                                   good call protection, which helps sustain the
                                   dividend and reduce the volatility of the
                                   fund. The All-American Fund currently has
                                   about $50 million invested in non-callable
                                   bonds, which should help ensure the strength
                                   of the dividend if interest rates continue to
                                   decline. Non-callable bonds cannot be repaid
                                   early by their issuers, ensuring that if
                                   interest rates decline, the portfolio will
                                   continue to receive the same coupon rates on
                                   those bonds as it did when rates were higher.
 
                                   Although the fund has historically held
                                   lower-rated (but still investment-grade
                                   quality) bonds to increase yield to
                                   shareholders, we have seen the yield
                                   differentials between AAA and BBB bonds
                                   narrow significantly over the past year. As
                                   long as credit spreads are tight, we will
                                   plan to take advantage of opportunities to
                                   purchase bonds with high credit quality at
                                   yields that are similar to bonds with lower
                                   ratings.
 
                                   As part of our value investing approach, we
                                   will also continue to look for bonds that
                                   offer good long-term value with the potential
                                   for appreciating returns. At Nuveen, our
                                   Research Department provides the in-depth
                                   expertise and practical knowledge--backed by
                                   a century of experience--that make the
                                   difference in uncovering bonds that perform
                                   well throughout market cycles. Our thorough
                                   research helps us find investment-grade
                                   quality bonds that offer the best
                                   values--such as bonds from specific regions
                                   and sectors that have the best potential for
                                   performance and appreciation. Recently,
                                   research helped us uncover a number of bonds
                                   that were eventually pre-refunded by

                                   their issuers, which adds tremendous value to
                                   the portfolio. We plan to continue to search
                                   for bonds with advance refunding potential,
                                   as well as those with lower (but still
                                   investment-grade quality) credit ratings that
                                   we feel are undervalued by the market as a
                                   whole.
 
                                   WHAT IS YOUR OUTLOOK FOR THE MUNICIPAL
                                   MARKET?
                                   Looking at the year ahead, we believe the
                                   overall market will continue to strike a good
                                   balance between supply and demand. We expect
                                   supply to increase as new issuers continue to
                                   enter the market. A continued decline in
                                   yields could also cause new supply to come to
                                   market through refunding of current debt. On
                                   the demand side, volatility in the equity
                                   markets, plus the potential for a weakening
                                   of the economy, could spark increased
                                   interest in bonds of all types.
 
                                   Overall, we expect the fund to continue to
                                   benefit from tight credit spreads, as we take
                                   advantage of opportunities to enhance the
                                   credit quality and structure of the
                                   portfolio.

                                   Dear Shareholder
 
                                   It is my pleasure to report to you on the
                                   performance of the Nuveen Flagship
                                   All-American Municipal Bond Fund, and to
                                   welcome new investors to our family of
                                   investments. Shareholders were rewarded
                                   during the fiscal year with the attractive
                                   tax-free income and consistent performance
                                   that are hallmarks of Nuveen's disciplined
                                   investment approach -- qualities that make
                                   this fund a good choice for those seeking a
                                   stable addition to their core investment
                                   portfolio.
 
                                   The fund's outstanding performance came
                                   during a volatile year in the municipal bond
                                   market, including a mid-1996 decline and a
                                   post-election rally. Our focus on
                                   high-quality bonds helped to control price
                                   swings, while the market's volatility created
                                   opportunities for the portfolio manager to
                                   add value and enhance the fund's yield. By
                                   continuing to seek out undervalued bonds in
                                   sectors and regions we believe are
                                   fundamentally strong, Nuveen was able to
                                   generate very attractive current yields for
                                   shareholders while also preserving capital.
 
                                   As of April 30, 1997, Class A shareholders in
                                   the All-American Municipal Bond Fund were
                                   receiving tax-free yields on net asset value
                                   of 5.38%. To match this yield, All-American
                                   investors in the 31% federal income tax
                                   bracket would have had to earn 7.80% from
                                   taxable, long-term alternatives.
 
                                   During the same period, this fund turned in
                                   impressive total return performance when
                                   compared with its peers. The All-American
                                   fund's Class A Shares outperformed the
                                   benchmark Lehman Municipal Bond Index,
                                   generating a

                                   total return of 8.23% compared with a total
                                   return of 6.63% for the Lehman Index.
 
                                   Nuveen has recently made significant and
                                   exciting additions to the investment options
                                   available to our shareholders -- additions
                                   that make it easier to keep more of what you
                                   earn. We introduced three new equity and
                                   balanced funds for investors seeking both
                                   long-term growth and current income. We also
                                   introduced new fund pricing options to make
                                   purchasing our mutual funds even more
                                   convenient, and we revamped our prospectuses
                                   and annual shareholder reports to make them
                                   easier to read and provide expanded
                                   information about the funds.
 
                                   Further, Nuveen's array of municipal bond
                                   funds is now one of the largest in the
                                   industry since our merger with Flagship
                                   Resources Inc. This merger offers you even
                                   greater access to the municipal market plus
                                   additional expertise, resources and increased
                                   efficiencies for our shareholders.
 
                                   On behalf of everyone at Nuveen, I thank you
                                   for your confidence in us and our family of
                                   investments. You can continue to depend on us
                                   for high-quality investment products that
                                   withstand the test of time. We look forward
                                   to serving you in the future.
 
                                   Sincerely,

                                   Answering Your Questions
 
                                   WHAT ARE THE INVESTMENT OBJECTIVES OF THE
                                   FUND?
                                   The fund aims to provide investors with a
                                   high level of tax-free income while
                                   preserving the capital that investors have
                                   entrusted to us. Many investors rely on their
                                   portfolio as a principal source of their
                                   ongoing financial security. To that end, we
                                   focus our portfolio strategy on preserving
                                   what Nuveen investors have accumulated while
                                   generating income to support a comfortable
                                   lifestyle.
 
                                   WHAT IS YOUR STRATEGY FOR MEETING THOSE
                                   OBJECTIVES?
                                   Rigorous research analysis and a value
                                   investing approach are at the foundation of
                                   this fund's strategies. Each is a Nuveen
                                   hallmark, and they go hand in hand.
 
                                   A value strategy means that we look for
                                   high-quality securities that are undervalued
                                   and attractively priced relative to the rest
                                   of the market. Nuveen Research helps identify
                                   those market sectors, geographic regions and
                                   bond structures likely to produce bonds whose
                                   long-term value is higher than their current
                                   prices would indicate.
 
                                   One current example of a region we've
                                   identified as undervalued is the Sun Belt.
                                   The growth of the Southeast and Southwest has
                                   resulted in a huge volume of municipal bond
                                   issuance, most of which is to provide
                                   essential services: schools, correctional
                                   facilities, and water and sewer systems. The
                                   combination of volume and quality has created
                                   tremendous opportunities to find value.
 
                                   That's not to say it's easy. There is more
                                   municipal market information out there than
                                   ever before, and the markets are more
                                   efficient. As a result, there are fewer
                                   opportunities to find value. But by focusing
                                   on quality issues with

                                   expect.
 
                                   HOW DID THE FUND PERFORM DURING THE YEAR AND
                                   WHAT KEY ECONOMIC AND MARKET FACTORS AFFECTED
                                   THE FUND'S PERFORMANCE?
                                   The All-American fund was one of the top
                                   performing funds in its Lipper category (4th
                                   of 231 national municipal bond funds),
                                   providing Class A shareholders with a total
                                   return of 8.23%. During this period, the
                                   Lehman Brothers Municipal Bond Index, which
                                   does not incur operating expenses or
                                   transaction costs, reported a 6.63% total
                                   return. Additionally, in keeping with
                                   Nuveen's policy of providing stable monthly
                                   dividends, the All-American fund began paying
                                   a stabilized dividend, ensuring consistent
                                   and regular cash flows to shareholders.
 
                                   With over 70% of the fund invested in
                                   investment-grade quality bonds rated "A",
                                   "Baa" or non-rated, the All-American fund's
                                   performance was greatly enhanced by the
                                   continuing compression of yield spreads and
                                   improving underlying credit fundamentals. To
                                   ensure ongoing total return performance,
                                   portfolio structure was improved by
                                   maintaining and improving call protection
                                   when appropriate. This, combined with
                                   selected opportunities to enhance the fund's
                                   income returns, contributed to an impressive
                                   total return performance.
 
                                   WHAT IS YOUR MARKET OUTLOOK FOR THE COMING
                                   YEAR?
                                   We continue to see an economic expansion
                                   characterized by low unemployment and little
                                   wage and price inflation pressures. The
                                   Federal Reserve has demonstrated its
                                   continued vigilance against inflation by
                                   making a pre-emptive rate hike at the end of
                                   March. We anticipate continued municipal
                                   market demand as individual investors focus
                                   on strategically rebalancing their portfolios
                                   and reducing their exposure to the volatility
                                   recently demonstrated by the equity market.

                                   By following a disciplined value strategy,
                                   and depending on sound research, the
                                   long-term outlook for our municipal bond
                                   funds -- and for Nuveen shareholders -- is
                                   very good. We will continue to look for
                                   opportunities in sectors like healthcare and
                                   public power and in regions like the Midwest
                                   and the Sun Belt, and to identify bonds that
                                   are structured in ways that make them
                                   attractive through a complete interest rate
                                   cycle.

              MANAGEMENT'S DISCUSSION OF ALABAMA FUND PERFORMANCE
 
                                   Dear Shareholder
 
                                   It's a pleasure to share with you the Nuveen
                                   Flagship Alabama Municipal Bond Fund's
                                   outstanding performance record for the 12
                                   months ended November 30, 1997. Over the past
                                   year, investors continued to enjoy
                                   attractive, tax-free dividends generated by
                                   the fund's portfolio of municipal bonds. As
                                   of November 30, 1997, Class A shareholders
                                   were receiving a current yield on net asset
                                   value of 4.81%. To match this yield,
                                   investors in the 33.5% combined federal and
                                   state income tax bracket would have had to
                                   earn at least 7.23% on taxable alternatives.
 
                                   During this same period, the fund provided
                                   Class A shareholders with a highly
                                   competitive total return on net asset value
                                   of 8.01% with income reinvested, far
                                   outpacing the average return of 6.76% for its
                                   peer group, the Lipper Alabama municipal bond
                                   fund category. You will find additional

                                   THE YEAR IN REVIEW
                                   Over the past year, U.S. investors have
                                   benefited from robust economic growth with
                                   little evidence of inflationary pressures.
                                   With unemployment rates at 20-year lows and
                                   the current economic expansion entering its
                                   seventh year, the presence of benign
                                   inflation has sparked debate over whether the
                                   traditional link between growth and inflation
                                   has been broken. During 1997, expectations
                                   that excess growth would generate inflation
                                   disrupted the markets on several occasions,
                                   most notably following the Federal Reserve's
                                   interest rate tightening in March and
                                   speeches by Fed Chairman Alan Greenspan.
                                   Still, falling commodity prices kept producer
                                   prices in check, while low import prices--due
                                   in part to the weakness in Asian

                                   markets--limited U.S. companies' ability to
                                   raise consumer prices. This combination has
                                   kept inflation subdued and the Federal
                                   Reserve "on hold" since March. The reduction
                                   in the federal deficit and passage of the
                                   Taxpayer Relief Act of 1997 offer additional
                                   encouragement to long-term fixed-income
                                   investors.
 
                                   HELPING YOU BUILD A BETTER PORTFOLIO
                                   The events of 1997 have focused renewed
                                   attention on the need for diversification and
                                   appropriate asset allocation. Stock market
                                   volatility, especially late in the year,
                                   provided a vivid illustration of the
                                   steadying effect that fixed-income
                                   investments can provide in a well-constructed
                                   investment portfolio. Nuveen mutual funds
                                   provide an excellent balance to other stock
                                   and bond investments. Your financial adviser

TED NEILD, MANAGING DIRECTOR       WHAT ECONOMIC AND MARKET FACTORS INFLUENCED
OF NUVEEN'S PORTFOLIO              THE
MANAGEMENT TEAM, TALKS ABOUT       PERFORMANCE OF MUNICIPAL BONDS OVER THE PAST
THE MUNICIPAL BOND MARKET AND      YEAR?
OFFERS INSIGHTS INTO FACTORS       Over the past 12 months, the performance of
THAT AFFECTED THE PERFORMANCE      the municipal bond market was influenced by
OF THE FUND OVER THE PAST          three major factors: the continued strength
YEAR.                              of the U.S. economy, minimal inflation and
                                   volatility in the equity markets. During
                                   1997, these factors contributed to a positive
                                   environment for fixed-income investments, as
                                   reflected in the steady-to-declining interest
                                   rates evident during the year.
 
                                   Between December 1996 and November 1997, the
                                   yield on the 30-year Treasury bond dropped
                                   from 6.36% to 6.05%, and the municipal market
                                   followed suit, as the yield on the Bond Buyer
                                   40 declined from 5.63% to 5.36%. The spread
                                   between tax-free municipal bonds and taxable
                                   Treasury bonds remained tight, making
                                   municipal bonds very attractive.
 
                                   HOW HAS THE FUND PERFORMED DURING THIS
                                   PERIOD?
                                   As Tim mentioned in his letter to
                                   shareholders, the fund performed very well
                                   during the one-year period ended November 30,
                                   1997. The total return on net asset value for
                                   Class A shares of the fund was 8.01%, which
                                   compares favorably with the one-year average
                                   return of 6.76% for the peer group of Alabama
                                   municipal bond funds tracked by Lipper
                                   Analytical Services--a 125 basis point
                                   difference. Once again, this fund was the top
                                   performer in its category, ranking first
                                   among the eight municipal bond funds in the
                                   grouping.

                                   GIVEN THE CURRENT MUNICIPAL MARKET, WHERE
                                   WERE YOU ABLE TO FIND VALUE?
                                   We concentrated on identifying individual
                                   bonds that enhanced the structure of the
                                   portfolio, allowing the fund to rally as the
                                   market moved forward. Specifically, we
                                   purchased longer duration bonds with good
                                   call protection at the lower prices available
                                   earlier this year. These bonds are going to
                                   be increasingly difficult to find as other
                                   market participants struggle to maintain good
                                   structure in their portfolios. We also
                                   executed "swaps" earlier in the year, which
                                   allowed the fund to maintain its tax-free
                                   distribution yield even as interest rates
                                   declined.
 
                                   WHAT ARE YOUR KEY STRATEGIES FOR THE COMING
                                   YEAR?
                                   To sustain such outstanding performance, we
                                   take a holistic approach to portfolio
                                   management--assessing all of the factors that
                                   determine a fund's performance and taking
                                   advantage of all of them to contribute to
                                   total return and dividend stability. In the
                                   coming year, one focus will be maintaining
                                   good call protection, which helps sustain the
                                   fund's dividend, regardless of the direction
                                   that interest rates take.
 
                                   While credit spreads are tight, we will
                                   continue to take advantage of opportunities
                                   to purchase bonds with high credit quality at
                                   yields that are similar to bonds with lower
                                   ratings. We believe that if credit spreads
                                   widen, these high-quality issues will
                                   increase in value relative to lower-rated
                                   bonds.
 
                                   WHAT IS YOUR OUTLOOK FOR THE MUNICIPAL
                                   MARKET?
                                   Looking at the year ahead, we believe the
                                   overall market will continue to strike a good
                                   balance between supply and demand. We expect
                                   supply to increase as new issuers continue to
                                   enter the market. A continued decline in

                                   yields could also cause new supply to come to
                                   market through refunding of current debt. On

                                   markets, plus the potential for a weakening
                                   of the economy, could spark increased
                                   interest in bonds of all types.
 
                                   The financial crises in Asia, coupled with
                                   the continued strength of the dollar and low
                                   commodity prices, are all contributing to the
                                   excellent inflation picture. This backdrop
                                   should help offset stronger labor markets and
                                   limit the effects of any bond market
                                   corrections. In the meantime, positive
                                   underlying fundamentals provide good support
                                   for the municipal market.

                                     a contingent deferred sales charge (CDSC)
                                     that begins at 5% for redemptions during

                                     after purchase. Class C shares have a 1%
                                     CDSC for redemptions within one year which
                                     is not reflected in the one-year total

                                   Dear Shareholder
 
                                   It's a pleasure to report to you on the
                                   performance of the Nuveen Flagship Alabama
                                   Municipal Bond Fund. Over the past year, the
                                   fund posted sizable gains. For the fiscal
                                   year ended May 31, 1997, the value of your
                                   investment rose 9.22% for Class A shares, if
                                   you chose to reinvest your tax-free income
                                   dividends.
 
                                   Over this 12-month period, the total return
                                   performance for the fund (with income
                                   reinvested) outpaced the 8.28% increase
                                   produced by the Lehman Brothers Municipal
                                   Bond Index, which is used to represent the
                                   broad municipal bond market on an unmanaged
                                   basis.
 
                                   In addition to substantial total returns,
                                   shareholders continue to enjoy very
                                   attractive current yields generated by a
                                   portfolio of quality bonds, which provide
                                   excellent income for investors. As of May 31,
                                   1997, shareholders were receiving tax-free
                                   yields on net asset value of 5.07% for Class
                                   A shares. To match this yield, investors in
                                   the 33.5% combined federal and state income
                                   tax bracket would have had to earn at least
                                   7.62% on taxable alternatives.
 
                                   These results were produced against a
                                   backdrop of continued economic expansion and
                                   the lowest unemployment rates in almost two
                                   decades, a combination that in the past has
                                   foreshadowed an increase in inflation. In
                                   March, the Federal Reserve made a pre-emptive
                                   strike by raising short-term interest rates

                                   returns continue to be good, but fear of

                                   municipals and led to increased volatility in

                                   markets. During this time, bonds have often
                                   been the bellwether for the direction of
                                   stocks. Whenever inflation talk is at its
                                   most rampant, the stock market has kept an
                                   eye on the bond market for its response
                                   before reacting.
 
                                   In the first six months of the year, the
                                   markets also focused on fiscal issues,
                                   including the federal budget accord and
                                   discussion of plans to reduce taxes and
                                   eliminate the deficit. The economy appeared
                                   to be moderating, corporate earnings reports
                                   continued to exhibit strength, and interest
                                   rates fell in the second quarter. All of this
                                   was positive news. The net effect is that the
                                   markets are better off now than at the
                                   beginning of the year, but the volatility
                                   experienced in getting there has been
                                   significant.
 
                                   Recently, the need for diversification and a
                                   renewed emphasis on asset allocation - as
                                   well as attractive yields - have sparked
                                   increased interest in tax-free investments.
                                   The current level of the stock market reminds
                                   investors to re-allocate profits to other
                                   segments of the market in order to limit
                                   risk. Nuveen municipal bond funds provide an
                                   excellent lower-risk alternative, and their
                                   current yields make them very attractive.
 
                                   On behalf of everyone at Nuveen, I thank you
                                   for your confidence in us and our family of
                                   investments. You can continue to depend on us
                                   for high-quality investments that withstand
                                   the test of time. We look forward to
                                   reporting to you again in six months.
 
                                   Sincerely,

                                   Answering Your Questions
 
TED NEILD, HEAD OF NUVEEN'S        WHAT ARE THE INVESTMENT OBJECTIVES OF THE
DAYTON-BASED PORTFOLIO             FUND?
MANAGEMENT TEAM, TALKS ABOUT       The fund aims to provide investors with a
THE MUNICIPAL BOND MARKET AND      high level of tax-free income while
OFFERS INSIGHTS INTO FACTORS       preserving capital by investing in a
THAT AFFECTED THE FUND             diversified portfolio of high-quality
PERFORMANCE OVER THE PAST          municipal bonds. To that end, we attempt to
YEAR.                              maximize the fund's after-tax total return by
                                   generating high tax-free income and
                                   minimizing the distribution of taxable
                                   capital gains when possible.
 
                                   WHAT IS YOUR STRATEGY FOR MEETING THESE
                                   OBJECTIVES?
                                   To meet this fund's objectives of income and
                                   enhanced value, our portfolio management
                                   strategy relies on conservative value
                                   investing principles, sound research and
                                   credit surveillance activities, and senior
                                   management involvement. At Nuveen, value
                                   investing means taking a fundamental approach
                                   to finding bonds that offer the best balance
                                   of high potential return with low risk
                                   regardless of the direction of interest
                                   rates. This approach focuses on the
                                   characteristics of individual bonds, such as
                                   sector, geographic region, structure and
                                   intrinsic credit quality, rather than on the
                                   general economic environment. The idea behind
                                   this philosophy is that we, as investment
                                   managers, can control the selection process,
                                   but not the direction of the economy as a
                                   whole.
 
                                   WHAT KEY ECONOMIC FACTORS AFFECTED
                                   THE FUND'S PERFORMANCE DURING THE YEAR?
                                   The U.S. economy continued to grow,
                                   exhibiting low unemployment, increased
                                   manufacturing and construction activity, and
                                   lack of price pressure at the consumer and
                                   producer levels.

                                   GIVEN THIS MARKET ENVIRONMENT,
                                   HOW DID THE FUND PERFORM?
                                   The Alabama Municipal Bond Fund performed
                                   well over the past year, rewarding investors
                                   with a total return on net asset value for
                                   the year of 9.22% for Class A shares,
                                   including price changes and reinvested
                                   dividends. Additionally, the fund was ranked
                                   number one among eight Alabama municipal bond
                                   funds for the one-year period by Lipper
                                   Analytical Services, a nationally recognized
                                   performance measurement service. Steady
                                   demand, coupled with tight supply, caused
                                   munis to outperform Treasury securities over
                                   the 12 month period.
 
                                   WHAT STRATEGIES DID YOU EMPLOY TO ADD VALUE?
                                   The fund maintained its average call
                                   protection at just over eight years. Where
                                   possible, we strive to extend the call
                                   protection to increase the upward price
                                   potential of callable municipal bonds during
                                   market rallies--such as the rally of the last
                                   12 months. The duration, a measure of the
                                   fund's volatility, was reduced somewhat
                                   during the year from 9.6 years to 8.16 years
                                   to reduce slightly the interest rate risk of
                                   the fund after the market's strong
                                   performance.
 
                                   WHAT IS THE CURRENT STATUS OF ALABAMA
                                   MUNICIPAL MARKET?
                                   Alabama's municipal market performed well in
                                   1996. A limited amount of issuance added to
                                   previously tight supply levels caused heavy
                                   demand for Alabama bonds. An economy once
                                   heavily reliant on agriculture is now
                                   increasingly dependent on manufacturing and
                                   service-related industries. Increases in
                                   infrastructures issuance are expected for the
                                   upkeep of one of the nation's largest inland
                                   river systems and busiest ports. State
                                   municipal bond issuance was down 8.1% to
                                   $1.18 billion in the first six months of
                                   1997.
 
                                   WHAT IS THE CURRENT OUTLOOK FOR THE MUNICIPAL
                                   MARKET
                                   AS A WHOLE?
                                   As we make our way through the seventh year
                                   of the current economic expansion, some
                                   observers believe that a fundamental shift
                                   may have occurred in our economy. Based on
                                   past experience and months of reports of

                                                                    May 31, 1997
 
                                   economic growth, especially employment
                                   statistics, the markets have long been
                                   anticipating an increase in inflation.
                                   However, even with almost full employment, we
                                   have not seen the expected rise in hourly
                                   wages that would be considered inflationary.
                                   This change in the traditional economic
                                   cause-and-effect relationship has been
                                   variously attributed to the globalization of
                                   the economy and consequent competitive
                                   pressures, to increased use of technology,
                                   and to corporations' recent ability to
                                   downsize as necessary. Although structural
                                   changes in the economy appear to have
                                   suspended the relationship between faster
                                   growth and higher inflation, the risk remains
                                   that inflation may reassert itself if
                                   capacity constraints are reached and
                                   resources are stretched too thin.
 
                                   Talk of Fed tightening will continue. If the
                                   Fed does act to increase rates, it will be
                                   perceived as a move against inflation. If the
                                   Fed does not tighten, it will be seen as an

                                   Nonetheless, for the remainder of 1997, the
                                   municipal market will continue to offer the
                                   attractive yields and tax advantages that
                                   make it a good alternative if and when a
                                   correction in the stock market occurs. While
                                   money continues to flow into equity mutual
                                   funds, investors are also beginning to
                                   evaluate the effect of the huge run-up in
                                   stock prices on their asset allocation, and
                                   many are rebalancing their portfolios by
                                   shifting some assets into bonds.

           MANAGEMENT'S DISCUSSION OF SOUTH CAROLINA FUND PERFORMANCE
 
                                   Dear Shareholder
 
                                   It's a pleasure to share with you the Nuveen
                                   Flagship South Carolina Municipal Bond Fund's
                                   outstanding performance record for the 12
                                   months ended November 30, 1997. Over the past
                                   year, investors continued to enjoy
                                   attractive, tax-free dividends generated by
                                   the fund's portfolio of municipal bonds. As
                                   of November 30, 1997, Class A shareholders
                                   were receiving a current yield on net asset
                                   value of 4.73%. To match this yield,
                                   investors in the 36% combined federal and
                                   state income tax bracket would have had to
                                   earn at least 7.39% on taxable alternatives.
 
                                   During this same period, the fund provided
                                   Class A shareholders with a highly
                                   competitive total return on net asset value
                                   of 7.64% with income reinvested, outpacing
                                   the average return of 6.44% for its peer
                                   group, the Lipper South Carolina municipal
                                   bond fund category. You will find additional
                                   details on the fund's performance on pages C6

                                   THE YEAR IN REVIEW
                                   Over the past year, U.S. investors have
                                   benefited from robust economic growth with
                                   little evidence of inflationary pressures.
                                   With unemployment rates at 20-year lows and
                                   the current economic expansion entering its
                                   seventh year, the presence of benign
                                   inflation has sparked debate over whether the
                                   traditional link between growth and inflation
                                   has been broken. During 1997, expectations
                                   that excess growth would generate inflation
                                   disrupted the markets on several occasions,
                                   most notably following the Federal Reserve's
                                   interest rate tightening in March and

                                   in part to the weakness in Asian

                                   HELPING YOU BUILD A BETTER PORTFOLIO
                                   The events of 1997 have focused renewed
                                   attention on the need for diversification and
                                   appropriate asset allocation. Stock market
                                   volatility, especially late in the year,
                                   provided a vivid illustration of the
                                   steadying effect that fixed-income
                                   investments can provide in a well-
                                   constructed investment portfolio. Nuveen
                                   mutual funds provide an excellent balance to

                                   Answering Your Questions
 
TED NEILD, MANAGING DIRECTOR       WHAT ECONOMIC AND MARKET FACTORS INFLUENCED
OF NUVEEN'S PORTFOLIO              THE PERFORMANCE OF MUNICIPAL BONDS OVER THE
MANAGEMENT TEAM, TALKS ABOUT       PAST YEAR?
THE MUNICIPAL BOND MARKET AND      Over the past 12 months, the performance of
OFFERS INSIGHTS INTO FACTORS       the municipal bond market was influenced by
THAT AFFECTED THE PERFORMANCE      three major factors: the continued strength
OF THE FUND OVER THE PAST          of the U.S. economy, minimal inflation, and
YEAR.                              volatility in the equity markets. During
                                   1997, these factors contributed to a positive
                                   environment for fixed-income investments, as
                                   reflected in the steady-to-declining interest
                                   rates evident during the year.
 
                                   Between December 1996 and November 1997, the
                                   yield on the 30-year Treasury bond dropped
                                   from 6.36% to 6.05%, and the municipal market
                                   followed suit, as the yield on the Bond Buyer
                                   40 declined from 5.63% to 5.36%. The spread
                                   between tax-free municipal bonds and taxable
                                   Treasury bonds remained tight, making
                                   municipal bonds very attractive.
 
                                   HOW HAS THE FUND PERFORMED DURING THIS
                                   PERIOD?
                                   As Tim mentioned in his letter to
                                   shareholders, the fund performed very well
                                   during the one-year period ended November 30,
                                   1997. The total return on net asset value for
                                   Class A shares of the fund was 7.64%, which
                                   compares favorably with the one-year average
                                   return of 6.44% for the peer group of South
                                   Carolina municipal bond funds tracked by
                                   Lipper Analytical Services--a 120 basis point
                                   difference. Once again, this fund was the top
                                   performer in its category, ranking first
                                   among the 16 municipal bond funds in the
                                   grouping.

                                                               November 30, 1997
 
                                   GIVEN THE CURRENT MUNICIPAL MARKET, WHERE
                                   WERE YOU ABLE TO FIND VALUE?
                                   The fund has benefited from a high embedded
                                   yield and extremely high quality holdings.
                                   Because of severe quality compression during
                                   the period, it was possible to increase
                                   investments in high quality, essential
                                   service municipal bonds. We also continued to
                                   look for value for shareholders in individual
                                   bonds that enhanced the structure of the
                                   portfolio, allowing the fund to rally as the
                                   market moved forward. Specifically, we
                                   purchased longer duration bonds with good
                                   call protection at the lower prices available
                                   earlier this year.
 
                                   Because of the limited issuance in South
                                   Carolina, home state bonds continue to demand
                                   a premium over bonds available in the general
                                   market. Retail demand exceeds the limited
                                   supply of South Carolina paper, so the fund
                                   continues to enjoy good execution of trades
                                   given our strong relationships with the
                                   broker-dealer community.
 
                                   WHAT ARE YOUR KEY STRATEGIES FOR THE COMING
                                   YEAR?
                                   We take a holistic approach to portfolio
                                   management--assessing all of the factors that
                                   determine a fund's performance and taking
                                   advantage of all of them to contribute to
                                   total return and dividend stability. In the
                                   coming year, one focus will be maintaining
                                   good call protection, which helps sustain the
                                   fund's dividend, regardless of the direction
                                   that interest rates take.
 
                                   We will continue to focus on sustaining a
                                   high level of tax-free income while
                                   maintaining the fund's favorable duration. We
                                   will look for opportunities to purchase
                                   housing bonds and essential service bonds
                                   with the assistance of Nuveen Research.
 
                                   While credit spreads are tight, we will
                                   continue to take advantage of opportunities
                                   to purchase bonds with high credit quality at
                                   yields that are similar to bonds with

                                   lower ratings. During the past year, the
                                   yield differentials between AAA and BBB bonds
                                   narrowed significantly. We believe that if
                                   credit spreads widen, these high-quality
                                   issues will increase in value relative to
                                   lower-rated bonds.
 
                                   WHAT IS YOUR OUTLOOK FOR THE MUNICIPAL
                                   MARKET?
                                   Looking at the year ahead, we believe the
                                   overall market will continue to strike a good
                                   balance between supply and demand. We expect
                                   supply to increase as new issuers continue to
                                   enter the market. A continued decline in
                                   yields could also cause new supply to come to
                                   market through refunding of current debt. On
                                   the demand side, volatility in the equity
                                   markets, plus the potential for a weakening
                                   of the economy, could spark increased
                                   interest in bonds of all types.
 
                                   The financial crises in Asia, coupled with
                                   the continued strength of the dollar and low
                                   commodity prices, are all contributing to the
                                   excellent inflation picture. This backdrop
                                   should help offset stronger labor markets and
                                   limit the effects of any bond market
                                   corrections. In the meantime, positive
                                   underlying fundamentals provide good support
                                   for the municipal market.

                                     redemptions within one year which is not
                                     reflected in the one-year total return.

                                   Dear Shareholder
 
                                   It's a pleasure to report to you on the
                                   performance of the Nuveen Flagship South
                                   Carolina Municipal Bond Fund. Over the past
                                   year, the fund posted sizable gains. For the
                                   fiscal year ended May 31, 1997, the value of
                                   your investment rose 8.28% for Class A shares
                                   if you chose to reinvest your tax-free income
                                   dividends.
 
                                   Over this 12-month period, the total return
                                   performance for the fund (with income
                                   reinvested) matched the 8.28% increase
                                   produced by the Lehman Brothers Municipal
                                   Bond Index, which is used to represent the
                                   broad municipal bond market on an unmanaged
                                   basis.
 
                                   In addition to substantial total returns,
                                   shareholders continue to enjoy very
                                   attractive current yields generated by a
                                   portfolio of quality bonds, which provide
                                   excellent income for investors. As of May 31,
                                   1997, shareholders were receiving tax-free
                                   yields on net asset value of 5.37% for Class
                                   A shares. To match this yield, investors in
                                   the 36% combined federal and state income tax
                                   bracket would have had to earn at least 8.39%
                                   on taxable alternatives.
 
                                   These results were produced against a
                                   backdrop of continued economic expansion and
                                   the lowest unemployment rates in almost two
                                   decades, a combination that in the past has
                                   foreshadowed an increase in inflation. In
                                   March, the Federal Reserve made a pre-emptive
                                   strike by raising short-term interest rates
                                   by 0.25%, but then maintained the status quo
                                   at its May and July meetings. Overall market
                                   returns continue to be good, but fear of
                                   inflation has hampered the performance of
                                   municipals and led to increased volatility in
                                   both the equity and bond markets. During this
                                   time, bonds have often been the

                                   bellwether for the direction of stocks.
                                   Whenever inflation talk is at its most
                                   rampant, the stock market has kept an eye on
                                   the bond market for its response before
                                   reacting.
 
                                   In the first six months of the year, the
                                   markets also focused on fiscal issues,
                                   including the federal budget accord and
                                   discussion of plans to reduce taxes and
                                   eliminate the deficit. The economy appeared
                                   to be moderating, corporate earnings reports
                                   continued to exhibit strength, and interest
                                   rates fell in the second quarter. All of this
                                   was positive news. The net effect is that the
                                   markets are better off now than at the
                                   beginning of the year, but the volatility
                                   experienced in getting there has been
                                   significant.
 
                                   Recently, the need for diversification and a
                                   renewed emphasis on asset allocation -- as
                                   well as attractive yields -- have sparked
                                   increased interest in tax-free investments.
                                   The current level of the stock market reminds
                                   investors to re-allocate profits to other
                                   segments of the market in order to limit
                                   risk. Nuveen municipal bond funds provide an
                                   excellent lower-risk alternative, and their
                                   current yields make them very attractive.
 
                                   On behalf of everyone at Nuveen, I thank you
                                   for your confidence in us and our family of
                                   investments. You can continue to depend on us
                                   for high-quality investments that withstand
                                   the test of time. We look forward to
                                   reporting to you again in six months.
 
                                   Sincerely,

                                   Answering Your Questions
 
TED NEILD, HEAD OF NUVEEN'S        WHAT ARE THE INVESTMENT OBJECTIVES OF THE
DAYTON-BASED PORTFOLIO             FUND?
MANAGEMENT TEAM, TALKS ABOUT       The fund aims to provide investors with a
THE MUNICIPAL BOND MARKET AND      high level of tax-free income while
OFFERS INSIGHTS INTO FACTORS       preserving capital by investing in a
THAT AFFECTED THE FUND             diversified portfolio of high-quality
PERFORMANCE OVER THE PAST          municipal bonds. To that end, we attempt to
YEAR.                              maximize the fund's after-tax total return by
                                   generating high tax-free income and
                                   minimizing the distribution of taxable
                                   capital gains when possible.
 
                                   WHAT IS YOUR STRATEGY FOR MEETING THESE
                                   OBJECTIVES?
                                   To meet this fund's objectives of income and
                                   enhanced value, our portfolio management
                                   strategy relies on conservative value
                                   investing principles, sound research and
                                   credit surveillance activities, and senior
                                   management involvement. At Nuveen, value
                                   investing means taking a fundamental approach
                                   to finding bonds that offer the best balance
                                   of high potential return with low risk
                                   regardless of the direction of interest
                                   rates. This approach focuses on the
                                   characteristics of individual bonds, such as
                                   sector, geographic region, structure and
                                   intrinsic credit quality, rather than on the
                                   general economic environment. The idea behind
                                   this philosophy is that we, as investment
                                   managers, can control the selection process,
                                   but not the direction of the economy as a
                                   whole.
 
                                   WHAT KEY ECONOMIC FACTORS AFFECTED THE FUND'S
                                   PERFORMANCE DURING THE YEAR?
                                   The U.S. economy continued to grow,
                                   exhibiting low unemployment, increased
                                   manufacturing and construction activity, and
                                   lack of price pressure at the consumer and
                                   producer levels. The fund had the added
                                   advantage of operating in a healthy supply
                                   environment, where securities were available
                                   as needed.

                                   GIVEN THIS MARKET ENVIRONMENT,
                                   HOW DID THE FUND PERFORM?
                                   The South Carolina Municipal Bond Fund
                                   performed well over the past year, rewarding
                                   investors with a total return on net asset
                                   value for the year of 8.28% for Class A
                                   shares, including price changes and
                                   reinvested dividends. The fund was ranked
                                   third among 15 South Carolina municipal bond
                                   funds for the one-year period by Lipper
                                   Analytical Services, a nationally recognized
                                   performance measurement service.
 
                                   WHAT STRATEGIES DID YOU EMPLOY TO ADD VALUE?
                                   We focused on taking advantage of the strong
                                   municipal bond market in South Carolina to
                                   improve the already-high credit quality of
                                   the fund. Strong demand for bonds in the
                                   state has allowed us to purchase quality
                                   bonds without affecting the income of the
                                   fund. In addition, we sold some insured lease
                                   bonds in favor of higher-quality bonds in
                                   sectors such as utilities, water and sewer
                                   facilities, and schools.
 
                                   WHAT IS THE CURRENT STATUS OF SOUTH
                                   CAROLINA'S
                                   MUNICIPAL MARKET?
                                   Though still reliant on the textile industry,
                                   South Carolina's economy has diversified into
                                   other areas such as trade, services and
                                   durable goods manufacturing. Steady economic
                                   gains are expected to continue as local
                                   companies' expansion plans contribute to
                                   future growth. Strong retail demand, in
                                   combination with the state's high-quality
                                   municipal issuers and this year's low
                                   issuance volume (under $1 billion through the
                                   first half of 1997), have kept South Carolina
                                   bonds aggressively priced.
 
                                   WHAT IS THE CURRENT OUTLOOK FOR THE MUNICIPAL
                                   MARKET
                                   AS A WHOLE?
                                   As we make our way through the seventh year
                                   of the current economic expansion, some
                                   observers believe that a fundamental shift
                                   may have occurred in our economy. Based on
                                   past experience and months of reports of
                                   economic growth, especially employment
                                   statistics, the markets have long been
                                   anticipating an increase in inflation.
                                   However, even with almost full employment, we

                                                                    May 31, 1997
 
                                   have not seen the expected rise in hourly
                                   wages that would be considered inflationary.
                                   This change in the traditional economic
                                   cause-and-effect relationship has been
                                   variously attributed to the globalization of
                                   the economy and consequent competitive
                                   pressures, to increased use of technology,
                                   and to corporations' recent ability to
                                   downsize as necessary. Although structural
                                   changes in the economy appear to have
                                   suspended the relationship between faster
                                   growth and higher inflation, the risk remains
                                   that inflation may reassert itself if
                                   capacity constraints are reached and
                                   resources are stretched too thin.
 
                                   Talk of Fed tightening will continue. If the
                                   Fed does act to increase rates, it will be
                                   perceived as a move against inflation. If the
                                   Fed does not tighten, it will be seen as an
                                   indication that the economy is doing well.
 
                                   Nonetheless, for the remainder of 1997, the
                                   municipal market should continue to offer the
                                   attractive yields and tax advantages that
                                   make it a good alternative if and when a
                                   correction in the stock market occurs. While
                                   money continues to flow into equity mutual
                                   funds, investors are also beginning to
                                   evaluate the effect of the huge run-up in
                                   stock prices on their asset allocation, and
                                   many are rebalancing their portfolios by
                                   shifting some assets into bonds.

                                     have a CDSC that declines from 5% to 0%
                                     after 6 years. Class C shares have a 1%
                                     CDSC for redemptions within one year.

Class R total returns reflect actual performance for all periods; Class A, B and
C total returns reflect actual performance for periods since class inception,
and Class R performance for periods prior to class inception (see "Financial
Highlights" for dates), adjusted for the differences in sales charges and fees
between the classes. Class B total returns assume an ongoing investment and do
not reflect the imposition of the CDSC; your returns for the 1 year and 5 year
periods would be lower if you redeemed at the end of those periods. See Overview
of Fund Operating Expenses and Shareholder Transaction Expenses.
 
The fund assumes investment risk in pursuit of its investment objective, chiefly
in the form of interest rate risk and credit risk. The fund limits this risk by
purchasing only certain types and maturities of municipal bonds and by
diversifying its investment portfolio geographically and by industry. See Risk
Reduction Strategies for further information.

 +  Annualized.
 
(a) Total returns are calculated on net asset value without any sales charge.
 
(b) After waiver of certain management fees or reimbursement of expenses, if
applicable, by Nuveen Advisory.
 
(c) From commencement of class operations as noted through February 28/29.
 
(d) For the five months ending February 29.
 
(e) For the year ending September 30.
 
(f) For the year ending February 28/29.
 
(g) For the two months ending April 30.
 
Notes:
 
(1) The Class A sales charge may be reduced or waived based on the amount of
purchase or for certain eligible categories of investors. A CDSC of 1% is
imposed on redemptions of certain purchases of $1 million or more within 18
months of purchase. See "How to Select a Purchase Option."
 
(2) CDSC declines to 0% at the end of six years.
 
(3) Imposed only on redemptions within 12 months of purchase.
 
(4) Effective February 1, 1997, the fund reduced the service fee on Class A and
C shares from 0.25% to 0.20% and reduced the distribution fee on Class C shares
from 0.75% to 0.55%. Long-term holders of Class B and C shares may pay more in
distribution fees and CDSCs than the maximum initial sales charge permitted
under National Association of Securities Dealers (NASD) Rules of Fair Practice.
Nuveen Advisory has agreed to waive some or all of its fees or reimburse
expenses to prevent total operating expenses (not counting distribution and
service fees) from exceeding 0.75% of the fund's average daily net assets.
 
(5) The expenses shown assume that you redeem your shares at the end of each
holding period. Class B shares convert to Class A shares after eight years. If
instead you redeemed your shares prior to the end of each stated period, your
expenses might be higher. If you did not redeem Class B shares at the end of
each holding period, your expenses would have been $15 for the one year period,
$48 for the three year period, $83 for the five year period, and $161 for the
ten year period. This example does not represent past or future expenses; actual
expenses may be higher or lower.

between the classes. Class B total returns assume an ongoing investment and do
not reflect the imposition of the CDSC; your returns for the 1 year and 5 year
periods would be lower if you redeemed at the end of those periods. See Overview
of Fund Operating Expenses and Shareholder Transaction Expenses.
 
The fund assumes investment risk in pursuit of its investment objective, chiefly
in the form of interest rate risk and credit risk. The fund limits this risk by
purchasing only certain types and maturities of municipal bonds and by
diversifying its investment portfolio geographically and by industry. See Risk
Reduction Strategies for further information.

(d) For the year ending February 28/29.
 
(e) For the two months ending April 30.
 
Notes:
 
(1) The Class A sales charge may be reduced or waived based on the amount of
purchase or for certain eligible categories of investors. A CDSC of 1% is
imposed on redemptions of certain purchases of $1 million or more within 18
months of purchase. See "How to Select a Purchase Option."
 
(2) CDSC declines to 0% at the end of six years.
 
(3) Imposed only on redemptions within 12 months of purchase.
 
(4) Effective February 1, 1997, the fund reduced the service fee on Class A and
C shares from 0.25% to 0.20% and reduced the distribution fee on Class C shares
from 0.75% to 0.55%. Long-term holders of Class B and C shares may pay more in
distribution fees and CDSCs than the maximum initial sales charge permitted
under National Association of Securities Dealers (NASD) Rules of Fair Practice.
Nuveen Advisory has agreed to waive some or all of its fees or reimburse
expenses to prevent total operating expenses (not counting distribution and
service fees) from exceeding 0.975% of the fund's average daily net assets.
 
(5) The expenses shown assume that you redeem your shares at the end of each
holding period. Class B shares convert to Class A shares after eight years. If
instead you redeemed your shares prior to the end of each stated period, your
expenses might be higher. If you did not redeem Class B shares at the end of
each holding period, your expenses would have been $16 for the one year period,
$50 for the three year period, $87 for the five year period, and $169 for the
ten year period. This example does not represent past or future expenses; actual
expenses may be higher or lower.

Class A total returns reflect actual performance for all periods; Class B, C and
R total returns reflect actual performance for periods since class inception
(see "Financial Highlights" for dates), and Class A performance for periods
prior to class inception, adjusted for the differences in sales charges and (in
the case of Classes B and C) fees between the classes. Class B total returns
assume an ongoing investment and do not reflect the imposition of the CDSC; your
returns for the 1 year and 5 year periods would be lower if you redeemed at the
end of those periods. See Overview of Fund Operating Expenses and Shareholder
Transaction Expenses.
 
The fund assumes investment risk in pursuit of its investment objective, chiefly
in the form of interest rate risk and credit risk. The fund limits this risk by
purchasing only certain types and maturities of municipal bonds and by
diversifying its investment portfolio geographically and by industry. See Risk
Reduction Strategies for further information.

 + Annualized.
 
 ++ Information included prior to the period ending April 30, 1997, reflects the
financial highlights of Flagship All-American.
 
+++ The amounts shown include a distribution in excess of capital gains of $.10
per share.
 
(a) Total returns are calculated on net asset value without any sales charge.
 
(b) After waiver of certain management fees or reimbursement of expenses, if
applicable, by Nuveen Advisory or its predecessor Flagship Financial.
 
(c) From commencement of class operations as noted through May 31.
 
(d) From commencement of class operations as noted through April 30.
 
(e) For the 11 months ending April 30.
 
(f) For the year ending May 31.
 
Notes:
 
(1) The Class A sales charge may be reduced or waived based on the amount of
purchase or for certain eligible categories of investors. A CDSC of 1% is
imposed on redemptions of certain purchases of $1 million or more within 18
months of purchase. See "How to Select a Purchase Option."
 
(2) CDSC declines to 0% at the end of six years.
 
(3) Imposed only on redemptions within 12 months of purchase.
 
(4) Effective February 1, 1997 the fund eliminated the 0.20% distribution fee on
Class A shares and reduced the distribution fee on Class C shares from 0.75% to
0.55%. Long-term holders of Class B and C shares may pay more in distribution
fees and CDSCs than the maximum initial sales charge permitted under National
Association of Securities Dealers (NASD) Rules of Fair Practice. The
waiver/reimbursement levels shown reflect Nuveen's current undertaking, made in
connection with its acquisition of Flagship Resources as described in "Fund
Service Providers--Investment Adviser," to continue Flagship's general
dividend-setting practices.
 
(5) The expenses shown assume that you redeem your shares at the end of each
holding period. Class B shares convert to Class A shares after eight years. If
instead you redeemed your shares immediately prior to the end of each stated
period, your expenses might be higher. If you did not redeem Class B shares at
the end of each holding period, your expenses would have been $16 for the one
year period, $49 for the three year period, $85 for the five year period, and
$165 for the ten year period. This example does not represent past or future
expenses; actual expenses may be higher or lower.

Class A total returns reflect actual performance for all periods; Class C and R
total returns reflect actual performance for periods since class inception (see
"Financial Highlights" for dates), and Class A performance for periods prior to
class inception, adjusted for the differences in sales charges and (in the case
of Class C) fees between the classes. See Overview of Fund Operating Expenses
and Shareholder Transaction Expenses.
 
The fund assumes investment risk in pursuit of its investment objective, chiefly
in the form of interest rate risk and credit risk. The fund limits this risk by
purchasing only certain types and maturities of municipal bonds and by
diversifying its investment portfolio geographically and by industry. See Risk
Reduction Strategies for further information.

 + Annualized.
 
 ++ Information included prior to the period ending April 30, 1997, reflects the
financial highlights of Flagship Intermediate.
 
+++ The amounts shown include a distribution in excess of capital gains of $.10
per share.
 
(a) Total returns are calculated on net asset value without any sales charge.
 
(b) After waiver of certain management fees or reimbursement of expenses, if
applicable, by Nuveen Advisory or its predecessor Flagship Financial.
 
(c) From commencement of class operations as noted through May 31.

(e) For the 11 months ending April 30.
 
(f) For the year ending May 31.
 
Notes:
 
(1) The Class A sales charge may be reduced or waived based on the amount of
purchase or for certain eligible categories of investors. A CDSC of 1% is
imposed on redemptions of certain purchases of $1 million or more within 18
months of purchase. See "How to Select a Purchase Option."
 
(2) Imposed only on redemptions within 12 months of purchase.
 
(3) Effective February 1, 1997, the fund eliminated the 0.20% distribution fee
on Class A shares and reduced the distribution fee on Class C shares from 0.75%
to 0.55%. Long-term holders of Class C shares may pay more in distribution fees
and CDSCs than the maximum initial sales charge permitted under National
Association of Securities Dealers (NASD) Rules of Fair Practice. The
waiver/reimbursement levels shown reflect Nuveen's current undertaking, made in
connection with its acquisition of Flagship Resources as described in "Fund
Service Providers--Investment Adviser," to continue Flagship's general
dividend-setting practices.
 
(4) The expenses shown assume that you redeem your shares at the end of each
holding period. If instead you redeemed your shares immediately prior to the end
of each stated period, your expenses might be higher. This example does not
represent past or future expenses; actual expenses may be higher or lower.

Class A total returns reflect actual performance for all periods; Class C and R
total returns reflect actual performance for periods since class inception (see
"Financial Highlights" for dates), and Class A performance for periods prior to
class inception, adjusted for the differences in sales charges and (in the case
of Class C) fees between the classes. See Overview of Fund Operating Expenses
and Shareholder Transaction Expenses.
 
The fund assumes investment risk in pursuit of its investment objective, chiefly
in the form of interest rate risk and credit risk. The fund limits this risk by
purchasing only certain types and maturities of municipal bonds and by
diversifying its investment portfolio geographically and by industry. See Risk
Reduction Strategies for further information.

 + Annualized.
 
++ Information included prior to the period ending April 30, 1997, reflects the
   financial highlights of Flagship Intermediate.
 
(a) Total returns are calculated on net asset value without any sales charge.
 
(b) After waiver of certain management fees or reimbursement of expenses, if
    applicable, by Nuveen Advisory or its predecessor Flagship Financial.
 
(c) From commencement of class operations as noted through May 31.
 
(d) From commencement of class operations through April 30.
 
(e) For the 11 months ending April 30.
 
(f) For the year ending May 31.
 
Notes:
 
(1) The Class A sales charge may be reduced or waived based on the amount of
purchase or for certain eligible categories of investors. A CDSC of 1% is
imposed on redemptions of certain purchases of $1 million or more within 18
months of purchase. See "How to Select a Purchase Option."
 
(2) Imposed only on redemptions within 12 months of purchase.
 
(3) Effective February 1, 1997, the fund eliminated the 0.20% distribution fee
on Class A shares and reduced the distribution fee on Class C shares from 0.50%
to 0.35%. Long-term holders of Class C shares may pay more in distribution fees
and CDSCs than the maximum initial sales charge permitted under National
Association of Securities Dealers (NASD) Rules of Fair Practice. The
waiver/reimbursement levels shown reflect Nuveen's current undertaking, made in
connection with its acquisition of Flagship Resources as described in "Fund
Service Providers--Investment Adviser," to continue Flagship's general
dividend-setting practices.
 
(4) The expenses shown assume that you redeem your shares at the end of each
holding period. If instead you redeemed your shares immediately prior to the end
of each stated period, your expenses might be higher. This example does not
represent past or future expenses; actual expenses may be higher or lower.
 
FUND STRATEGIES
 
INVESTMENT OBJECTIVE
 
The investment objective of each fund is to provide you with as high a level of
current interest income exempt from regular federal income taxes as is
consistent with preservation of capital. There is no assurance that the funds
will achieve their investment objective.
 
 15
<PAGE>   91
 
INVESTOR SUITABILITY
 
The funds are a suitable investment for tax-conscious investors seeking to:
 
- - Earn regular monthly tax-free dividends;
 
- - Preserve investment capital over time;
 
- - Reduce taxes on investment income;
 
- - Set aside money systematically for retirement, estate planning or college
  funding.
 
The funds are not a suitable investment for individuals seeking to:
 
- - Pursue an aggressive, high-growth investment strategy;
 
- - Invest through an IRA or 401k plan;
 
- - Avoid fluctuations in share price.
 
HOW THE FUNDS SELECT INVESTMENTS
 
TAX-FREE MUNICIPAL BONDS
 
The funds invest primarily in municipal bonds that pay interest that is exempt
from regular federal income taxes. Income from these bonds may be subject to the
federal alternative minimum tax.
 
Municipal bonds are either general obligation or revenue bonds and typically are
issued to finance public projects (such as roads or public buildings), to pay
general operating expenses, or to refinance outstanding debt. Municipal bonds
may also be issued for private activities, such as housing, medical and
educational facility construction, or for privately owned industrial development
and pollution control projects. General obligation bonds are backed by the full
faith and credit, or taxing authority, of the issuer and may be repaid from any
revenue source; revenue bonds may be repaid only from the revenues of a specific
facility or source.
 
The Nuveen Insured Fund primarily purchases insured municipal bonds. See
"Insurance" below. Under normal market conditions, the Nuveen Insured Fund will
invest at least 65% of its assets in insured municipal bonds.
 
FOCUS ON QUALITY MUNICIPAL BONDS
 
The funds purchase only quality municipal bonds that are either rated investment
grade (AAA/Aaa to BBB/Baa) by independent ratings agencies at the time of
purchase or are non-rated but judged to be investment grade by the funds'
investment adviser. Each fund except the Insured Municipal Bond Fund will invest
at least 80% of its net assets in investment-grade quality bonds. The Insured
Municipal Bond Fund will invest at least 80% of its net assets in insured
municipal bonds or municipal bonds backed by an escrow or trust account that
contains sufficient U.S. government-backed securities to assure timely payment
of interest and principal.
 
The funds may purchase municipal bonds that represent lease obligations. These
carry special risks because the issuer of the bonds may not be obligated to
appropriate money annually to make payments under the lease. In order to reduce
this risk, the funds will only purchase leases where the issuer has a strong
incentive to continue making appropriations until maturity.
 
Bond ratings are furnished by Standard & Poor's Corporation, Fitch Investors
Services, and Moody's Investors Services. The ratings BBB and Baa are not
identical -- S&P and Fitch consider bonds rated BBB to have adequate capacity to
pay principal and interest; Moody's considers bonds rated Baa to have some
speculative characteristics. Bond ratings represent the opinions of the ratings
agencies; they are not absolute standards of quality.
 
VALUE INVESTING STRATEGY
 
The funds' investment adviser uses a value-oriented strategy and looks for
higher-yielding and undervalued municipal bonds that offer above-average total
return potential. The adviser emphasizes fundamental research and selects
municipal bonds on the basis of its evaluation of each bond's relative value in
terms of current yield, price, credit quality and future prospects. The adviser
then monitors each fund's portfolio to assure that municipal bonds purchased
continue to represent over time, in its opinion, the best values available.
 
PORTFOLIO MATURITY
 
Each fund purchases municipal bonds with different maturities in pursuit of its
investment objective, but maintains under normal market conditions an investment
portfolio with an overall weighted average maturity within a defined range. The
Limited-Term Fund maintains a weighted average portfolio maturity of 1 to 7
years. The Intermediate Fund maintains a
 
 16
<PAGE>   92
 
weighted average portfolio maturity of 5 to 10 years. All of the other three
funds described in this prospectus are long-term funds and normally maintain a
weighted average portfolio maturity of 15 to 30 years. See "Defensive Investment
Strategies" below for further information.
 
INSURANCE
 
The Insured Municipal Bond Fund primarily purchases insured municipal bonds.
Insured municipal bonds are either covered by individual, permanent insurance
policies (obtained either at the time of issuance or subsequently), or covered
"while in fund" under a master portfolio insurance policy purchased by a fund.
Insurance guarantees only the timely payment of interest and principal on the
bonds; it does not guarantee the value of either individual bonds or fund
shares.
 
Portfolio insurance policies are effective only so long as the fund continues to
own the covered bond, and the price the fund would receive upon sale of such a
bond would not benefit from the insurance. Insurers under master portfolio
insurance policies currently include MBIA Insurance Corp., AMBAC Indemnity
Corp., Financial Security Assurance, Inc., and Financial Guaranty Insurance Co.
The funds' investment adviser may obtain master policies from other insurers,
but only from insurers that specialize in insuring municipal bonds and whose
claims-paying ability is rated Aaa or AAA by Moody's or S&P. Insurers are
responsible for making their own assessment of the insurability of a municipal
bond.
 
The Insured Municipal Bond Fund can invest up to 20% of its net assets in
uninsured municipal bonds that are backed by an escrow containing sufficient
U.S. Government or U.S. Government agency securities to ensure timely payment of
principal and interest. Such bonds are normally regarded as having the credit
characteristics of the underlying U.S. Government-backed securities.
 
PORTFOLIO TURNOVER
 
A fund buys and sells portfolio securities in the normal course of its
investment activities. The proportion of the fund's investment portfolio that is
sold and replaced with new securities during a year is known as the fund's
portfolio turnover rate. The funds intend to keep portfolio turnover relatively
low in order to reduce trading costs and the realization of taxable capital
gains. Each fund, however, may make limited short-term trades to take advantage
of market opportunities or reduce market risk.
 
DELAYED DELIVERY TRANSACTIONS
 
Each fund may buy or sell bonds on a when-issued or delayed delivery basis,
making payment or taking delivery at a later date, normally within 15 to 45 days
of the trade date. This type of transaction may involve an element of risk
because no interest accrues on the bonds prior to settlement and, since
securities are subject to market fluctuation, the value of the bonds at time of
delivery may be less (or more) than cost.
 
RISK REDUCTION STRATEGIES
 
In pursuit of its investment objective, each fund assumes investment risk,
chiefly in the form of interest rate and credit risk. Interest rate risk is the
risk that changes in market interest rates will affect the value of a fund's
investment portfolio. In general, the value of a municipal bond falls when
interest rates rise, and increases when interest rates fall. Credit risk is the
risk that an issuer of a municipal bond is unable to meet its obligation to make
interest and principal payments. In general, lower rated municipal bonds are
perceived to carry a greater degree of risk in the issuer's ability to make
interest and principal payments. Municipal bonds with longer maturities
(durations) or lower ratings generally provide higher current income, but are
subject to greater price fluctuation due to changes in market conditions than
bonds with shorter maturities or higher ratings, respectively.
 
The funds limit your investment risk generally by restricting the types and
maturities of municipal bonds they purchase, and by diversifying their
investment portfolios geographically as well as across different industry
sectors. The funds should be considered long-term investments and may not be
suitable for investors with short-term investment horizons.
 
INVESTMENT LIMITATIONS
 
The funds have adopted certain investment limitations (based on total fund
assets) designed to limit your investment risk and maintain portfolio
diversification. Each fund may not have more than:
 
- - 5% in securities of any one issuer (except U.S. government securities or for
  25% of each fund's assets).
 
- - 25% in any one industry sector, such as electric utilities or health care;
 
- - 10% in borrowings (33% if used to meet redemptions).
 
 17
<PAGE>   93
 
DEFENSIVE INVESTMENT STRATEGIES
 
Each fund may invest in high quality short-term municipal securities in order to
reduce risk and preserve capital. Under normal market conditions, each fund may
invest only up to 20% of net assets in short-term municipal securities that are
exempt from regular federal income tax, although the funds may invest up to 100%
as a temporary defensive measure in response to adverse market conditions.
During temporary defensive periods, the weighted average maturity of a fund's
investment portfolio may fall below the defined range described above under
"Portfolio Maturity."
 
If suitable short-term municipal investments are not reasonably available, the
funds may invest in short-term taxable securities that are rated Aaa or AAA, by
Moody's or S&P, respectively, or issued by the U.S. government, and that have a
maturity of one year or less or have a variable interest rate.
 
Each fund may also use various investment strategies designed to limit the risk
of bond price fluctuations and to preserve capital. These hedging strategies
include using financial futures contracts, options on financial futures, or
options based on either an index of long-term tax-free securities or on debt
securities whose prices, in the opinion of the funds' investment adviser,
correlate with the prices of the funds' investments. The funds, however, have no
present intent to use these strategies.
 
FUNDAMENTAL INVESTMENT POLICIES
 
Each fund's investment objective as well as the policies described above in
"Focus on Quality Municipal Bonds," "Insurance," and "Risk Reduction Strategies"
are fundamental and may not be changed without the approval of a majority of the
shareholders of each fund.
 
INVESTING IN THE FUNDS
 
HOW TO BUY FUND SHARES
 
You may open an account with $3,000 per fund share class and make additional
investments at any time with as little as $50. Reinvestment of Nuveen unit trust
distributions have no purchase minimums. Purchases through sponsors of fee-based
programs meeting certain criteria, as described in the statement of additional
information, may be eligible for lower minimums. The share price you pay will
depend on when Nuveen receives your order: orders received before the close of
regular trading on the New York Stock Exchange (normally 4 p.m. Eastern time)
will receive that day's share price; otherwise you will receive the next
business day's share price.
 
BUYING SHARES THROUGH A FINANCIAL ADVISER
 
You may buy fund shares through your financial adviser, who can handle all the
details for you, including establishing an account with Nuveen. Financial
advisers can also help you review your financial needs and formulate long-term
investment goals and objectives. In addition, financial advisers generally can
help you develop a customized financial plan, select investments, and monitor
and review your portfolio on an ongoing basis to assure your investments
continue to meet your needs as circumstances change.
 
Financial advisers are usually paid either from fund sales charges and fees or
by charging you a separate fee in lieu of a sales charge for ongoing investment
advice and services.
 
If you do not have a financial adviser, call (800) 621-7227 and Nuveen can refer
you to one in your area.
 
BUYING SHARES BY MAIL
 
You may also open an account and purchase shares by mail by completing the
enclosed Nuveen application and mailing it along with your check (payable to the
appropriate fund) to the address listed under "How to Contact Nuveen." Sales
charges are not waived when you buy shares by mail.
 
Each fund reserves the right to reject any purchase order and waive or increase
minimum investment requirements. The funds also reserve the right to suspend the
issuance of shares at any time; any suspension, however, will not affect your
ability to redeem shares.
 
HOW TO SELECT A PURCHASE OPTION
 
The funds offer you a variety of flexible options when buying shares. Whether
you typically work with a financial adviser on a commission or a fee basis or
prefer to work on a more self-directed basis, you can purchase shares in the way
that is most suited to your individual circumstances and investment needs. Each
of the four available ways to purchase fund shares is called a class of shares:
Class A, Class B, Class C and Class R. While each of these classes features
different sales charges, on-going fees and eligibility requirements, each
entitles you to a share of the same portfolio of municipal bonds.
 
 18
<PAGE>   94
 
Selecting the class of shares which is most appropriate for you will depend on a
variety of factors. You should weigh carefully whether you and your financial
adviser work on a commission or fee basis, the types of services that you will
receive, the amount you intend to buy, how long you plan to own your investment
and whether or not you will reinvest dividends. If you compensate your financial
adviser directly, you should consider the fees your financial adviser charges
for investment advice or handling your trades in addition to any sales charges
and fees imposed by the funds. Please refer to your financial adviser's sales
material for further information. Each class of shares is described in more
detail below and under "Fund Service Providers -- The Distributor." Your
financial adviser can explain each option and help you determine which is most
appropriate for you, or you can call (800) 621-7227.
 
BUYING CLASS A SHARES
 
You may buy Class A shares at their public offering price on the day of
purchase. The price you pay will equal the Class A NAV (net asset value) plus a
sales charge based upon the amount of your purchase. Class A shares also bear a
0.20% annual service fee which compensates your financial adviser for providing
you with ongoing service.
 
The following Class A sales charges and commissions apply to all funds described
in this prospectus except the Intermediate Fund and Limited Term Funds.

(1) Nuveen pays authorized dealers a commission equal to the sum of 1% of the
first $2.5 million, plus 0.50% of the next $2.5 million, plus 0.25% of any
amount over $5 million. Unless the authorized dealer waived the commission, you
may be assessed a contingent deferred sales charge (CDSC) of 1% if you redeem
any of your shares within 18 months of purchase. The CDSC is calculated on the
lower of your purchase price or redemption proceeds.

Nuveen periodically undertakes sales promotion programs with authorized dealers
and may pay them the full applicable sales charge as a commission. In addition,
Nuveen may provide support to authorized dealers in connection with sales
meetings, seminars, prospecting seminars and other events at which Nuveen
presents its products and services. Under certain circumstances, Nuveen may also
make ongoing payments to authorized dealers to facilitate the marketing and
administration of new and existing shareholder accounts, including payments for
advertising that features the products and services of both parties. The
statement of additional information contains further information about these
programs. Nuveen pays for these programs at its own expense and not out of fund
assets.
 
OTHER SALES CHARGE DISCOUNTS
 
Nuveen offers a number of programs that enable you to reduce or eliminate the
sales charge on Class A shares:
 
Sales Charge Reductions
 
- - Rights of Accumulation
 
- - Letter of Intent (LOI)
 
- - Group Purchase
 
Sales Charge Waivers
 
- - Nuveen Unit Trust Reinvestment
 
- - Purchases using Redemptions from Unrelated Funds
 
- - Fee-Based Programs
 
- - Bank Trust Departments
 
- - Certain Employees of Nuveen or Authorized Dealers
 
Please refer to the statement of additional information for detailed
descriptions of these programs. Further information on these programs is also
available through your financial adviser or by calling (800) 621-7227. Your
financial adviser can also provide and help you prepare the necessary
application forms. You or your financial adviser are responsible for notifying
Nuveen about your eligibility for any sales charge reduction or waiver at the
time of each purchase.
 
The funds may modify or discontinue these programs at any time upon written
notice to shareholders.
 
BUYING CLASS B SHARES
 
You may buy Class B shares at their public offering price on the day of
purchase. The price you pay will equal the Class B NAV. There is no initial
sales charge, but Class B shares bear a 0.20% annual service fee which
compensates your financial adviser for providing you with ongoing service, and a
0.75% annual distribution fee which compensates Nuveen for paying your financial
adviser a 4% commission at the time of purchase. The Intermediate Fund and
Limited Term Fund do not currently offer B Shares.
 
Class B shares convert automatically to Class A shares eight years after
purchase. Class B shares will convert only if the fund is assured that the
conversion does not generate tax consequences for investors, based upon the
opinion of outside counsel or the written assurance of the IRS.
 
CLASS B CONTINGENT DEFERRED SALES CHARGE
 
If you redeem Class B shares within six years of purchase, you will be assessed
a contingent deferred sales charge (CDSC) based upon the following schedule:
 
The CDSC is calculated on the lower of your purchase price or redemption
proceeds.

0.55% (0.35% for the Limited Term Fund) annual distribution fee which
compensates Nuveen for paying your financial adviser for the sale, including a
1% commission at the time of sale.
 
If you redeem your Class C shares within one year of purchase, you may be

You may purchase Class R shares at their public offering price on the day of
purchase. The price you pay will equal the Class R NAV. You may purchase Class R
shares only if you are investing at least $1 million or would otherwise qualify
to purchase Class A shares without a sales charge under certain of the programs
described under "Other Sales Charge Discounts" above. See the statement of
additional information for more details. There are no sales charges or ongoing
fees. Class R shares have lower ongoing expenses than Class A shares.
 
HOW TO SELL FUND SHARES
 
You may use one of the methods described below to redeem your shares on any day
the New York Stock Exchange is open. You will receive the share price next
determined after Nuveen has received your redemption request in good order. Your
redemption request must be received before the close of trading of the New York
Stock Exchange (normally 4 p.m. Eastern time) for you to receive that day's
price. The funds do not charge any redemption fees, although you will be
assessed a CDSC where applicable.
 
SELLING SHARES THROUGH YOUR FINANCIAL ADVISER
 
You may sell fund shares by contacting your financial adviser who can provide
and help you prepare all the necessary documentation. Your financial adviser may
charge you for this service.
 
SELLING SHARES BY TELEPHONE
 
Unless you have declined telephone redemption privileges, you may sell fund
shares by calling (800) 621-7227. Your redemption must not exceed $50,000 and
you may not redeem by telephone shares held in certificate form. Checks will be
issued only to the shareholder on record and mailed to the address on record. If
you have established electronic funds transfer privileges on your account, you
may have redemption proceeds transferred electronically to your bank account; if
you are redeeming $1,000 or more, you may expedite your request by having your
redemption proceeds wired directly into your bank account. See "Fund
Direct--Electronic Funds Transfer" below.
 
Nuveen, the transfer agent or the fund will be liable for losses resulting from
unauthorized telephone redemptions only if they do not follow reasonable
procedures designed to verify the identity of the caller. You should immediately
verify your trade confirmations when you receive them.
 
SELLING SHARES BY MAIL
 
You may sell fund shares by mail by sending a written request to Nuveen at the
address listed below under "How to Contact Nuveen." Your request must include
the following information:
 
- - The fund's name;
 
- - Your name and account number;
 
- - The dollar or share amount you wish to redeem;
 
- - The signature of each owner exactly as it appears on the account;
 
- - The name of the person you want your redemption proceeds paid to, if other
  than to the shareholder of record;
 
- - The address you want your redemption proceeds sent to, if other than the
  address of record;
 
- - Any certificates you have for the shares; and
 
- - Any required signature guarantees.
 
Signatures must be guaranteed if you are redeeming more than $50,000, you want
the check payable to someone other than the shareholder on record, or you want
the check sent to another address (or the address on record has been changed
within the last 60 days). Signature guarantees must be obtained from a bank,
brokerage firm or other financial intermediary that is a member of an approved
Medallion Guarantee Program or that is otherwise approved by the fund. A notary
public cannot provide a signature guarantee.
 
Unless other arrangements are made, checks will be sent to your address on
record. Checks will normally be mailed within one business day, but in no event
more than seven days from receipt of your redemption request. If any shares were
purchased less than 15 days prior to your request, the fund will not mail your
redemption proceeds until the check for your purchase has cleared, which may
take up to 15 days.
 
Each fund may suspend redemptions or delay payment on redemptions for more than
seven days (three days for street name accounts) in certain extraordinary
circumstances as described in the statement of additional information.

<PAGE>   97
 
OPERATION OF THE CDSC
 
When you redeem Class A, Class B, or Class C shares subject to a CDSC, the fund
will first redeem any shares that are not subject to a CDSC or that represent an
increase in the value of your fund account due to capital appreciation, and then
redeem the shares you have owned for the longest period of time, unless you ask
the fund to redeem your shares in a different order. No CDSC is imposed on
shares you buy through the reinvestment of dividends and capital gains. The
holding period is calculated on a monthly basis and begins on the first day of
the month in which you buy shares. When you redeem shares subject to a CDSC, the
CDSC is calculated on the lower of your purchase price or redemption proceeds,
deducted from your redemption proceeds, and paid to Nuveen. The CDSC may be
waived under certain special circumstances as described in the statement of
additional information.
 
ACCOUNT MINIMUMS
 
From time to time, the funds may establish minimum account size requirements.
The funds reserve the right to liquidate your account upon 30 days written
notice if the value of your account falls below an established minimum. The
funds presently have set a minimum balance of $100 unless you have an active
unit trust reinvestment account. You will not be assessed a CDSC on an
involuntary redemption.
 
EXCHANGING SHARES
 
You may exchange fund shares at any time for the same class of shares in another
Nuveen mutual fund registered for sale in your state. You may exchange fund
shares by calling (800) 621-7227 or by mailing your written request to Nuveen at
the address listed under "How to Contact Nuveen."
 
You must have owned your fund shares for at least 15 days and your exchange must
meet the minimum purchase requirements of the fund into which you are
exchanging. No CDSC will be assessed on an exchange, and the holding period of
your investment will be carried over to the new fund for purposes of determining
any future CDSC. You may not exchange Class B shares for shares of a Nuveen
money market fund.
 
Because an exchange is treated for tax purposes as the concurrent sale and
purchase of fund shares, you should consult your tax adviser about the tax
consequences of any contemplated exchange. Each fund reserves the right to limit
or terminate exchange privileges if it believes doing so is in the best
interests of fund shareholders.
 
RESTRICTIONS ON MARKET TIMING
 
The exchange privilege is not intended to permit you to use a fund for shortterm
trading. Excessive exchange activity may interfere with portfolio management,
raise fund operating expenses or otherwise have an adverse effect on fund
shareholders. In order to limit excessive exchange activity and in other
circumstances where the funds' investment adviser believes doing so would be in
the best interests of the fund, each fund reserves the right to revise or
terminate the exchange privilege, limit the amount or number of exchanges, or
reject any exchange. You will be notified in the event this happens to the
extent required by law.
 
OPTIONAL FEATURES AND SERVICES
 
SYSTEMATIC INVESTMENT
 
Once you have opened an account, you may make regular investments of $50 or more
a month through automatic deductions from your bank account (see "Fund
Direct--Electronic Funds Transfer" below), or directly from your paycheck. To
invest regularly from your bank account, simply complete the appropriate section
of the account application. To invest regularly from your paycheck, call Nuveen
for a Payroll Direct Deposit Enrollment form. If you need additional copies of
these forms, or would like assistance completing them, contact your financial
adviser or call Nuveen at (800) 621-7227.
 
One of the benefits of systematic investing is "dollar cost averaging." Because
you are making fixed payments, you buy fewer shares when the price is high, and
more when the price is low. As a result, the average price you pay will be less
than the average share price of fund shares over this period. Dollar cost
averaging does not assure profits or protect against losses in a steadily
declining market. Since dollar cost averaging involves continuous investment
regardless of fluctuating price levels, you should consider your financial
ability to continue investing in declining as well as rising markets before
deciding to invest in this way.
 
Systematic investing may also make you eligible for reduced sales charges on
shares of the fund as well as other Nuveen mutual funds (see "Other Sales Charge
Discounts").
 
 22
<PAGE>   98
 
THE POWER OF SYSTEMATIC INVESTING
 
The chart below illustrates the benefits of systematic investing based on a
$3,000 initial investment and subsequent monthly investments of $100 over 20
years. The example assumes you earn a return of 4%, 5% or 6% annually on your
investment and that you reinvest all dividends. These annual returns do not
reflect past or projected fund performance.

                             [PLOT POINTS TO COME]
 
SYSTEMATIC WITHDRAWALS
 
If the value of your fund account is at least $10,000, you may request to have
$50 or more withdrawn automatically from your account. You may elect to receive
payments monthly, quarterly, semi-annually or annually, and may choose to
receive a check, have the monies transferred directly into your bank account
(see "Fund Direct--Electronic Funds Transfer" below), paid to a third party or
sent payable to you at an address other than your address of record. You must
complete the appropriate section of the account application or Account Update
Form to participate in the fund's systematic withdrawal plan.
 
You should not establish systematic withdrawals if you intend to make concurrent
purchases of Class A, B or C shares because you may unnecessarily pay a sales
charge or CDSC on these purchases.
 
REINSTATEMENT PRIVILEGE
 
If you redeem fund shares, you may reinvest all or part of your redemption
proceeds in shares of the same class up to one year later without incurring any
applicable sales charges, and your prior holding period will be reinstated. You
may exercise this privilege only once per redemption request.
 
If you paid a CDSC, your CDSC will be refunded and your holding period
reinstated. You should consult your tax adviser about the tax consequences of
exercising your reinstatement privilege.
 
FUND DIRECT--ELECTRONIC FUNDS TRANSFER
 
You may arrange to transfer funds electronically between your bank account and
your fund account by completing the appropriate section of the account
application or the Account Update Form. If you need additional copies of these
forms, or would like assistance completing them, contact your financial adviser
or call Nuveen at (800) 621-7227. You may use Fund Direct to quickly and
conveniently purchase or sell shares by telephone, systematically invest or
withdraw funds, or send dividend payments directly to your bank account.
 
In addition, if you have established electronic funds transfer privileges on
your account, you may request that redemption proceeds of $1,000 or more be sent
by Federal Reserve wire directly into your bank account. While you will
generally receive your redemption proceeds more quickly than a regular telephone
redemption via Fund Direct, the fund may charge you a fee for this expedited
service.
 
DIVIDENDS AND TAXES
 
HOW THE FUNDS PAY DIVIDENDS
 
The funds pay tax-free dividends monthly and any taxable capital gains or other
distributions once a year in December. The funds declare dividends on or about
the ninth of each month and generally pay dividends on the first business day of
the following month.
 
 23
<PAGE>   99
 
PAYMENT AND REINVESTMENT OPTIONS
 
The funds automatically reinvest your dividends each month in additional fund
shares of the same share class unless you request otherwise. You may request to
have your dividends paid to you by check, deposited directly into your bank
account, paid to a third party, sent to an address other than your address of
record or reinvested in shares of the same share class of another Nuveen mutual
fund. If you wish to do so, complete the appropriate section of the account
application, contact your financial adviser or call Nuveen at (800) 621-7227.
 
CALCULATION OF FUND DIVIDENDS
 
Each fund pays dividends based upon its past and projected net income in order
to distribute substantially all of its net income each fiscal year.
 
In order to maintain a more stable monthly dividend, each fund may sometimes
distribute less or more than the amount of net income earned in a particular
period as a result of fluctuations in a fund's net income. Undistributed net
income is included in the fund's share price; similarly, distributions from
previously undistributed net income reduce the fund's share price. This dividend
policy is not expected to affect the management of a fund's portfolio.
 
Dividends for Class A, B, C and R shares are determined in the same manner and
at the same time. Dividends per share will vary based on which class of fund
shares you own, reflecting the different ongoing fees and other expenses of each
class.
 
TAXES AND TAX REPORTING
 
The discussion below and in the statement of additional information provides
general tax information related to an investment in fund shares. Because tax
laws are complex and often change, you should consult your tax adviser about the
tax consequences of a specific fund investment.
 
Because the funds invest in municipal bonds, the regular monthly dividends you
receive will be exempt from regular federal income tax. All or a portion of
these dividends, however, may be subject to state and local taxes or to the
federal alternative minimum tax (AMT).
 
Although the funds do not seek to realize taxable income or capital gains, the
funds may realize and distribute taxable income or capital gains from time to
time as a result of each fund's normal investment activities. Each fund will
distribute in December any taxable income or capital gains realized over the
preceding year. Net short-term gains are taxable as ordinary income. Net
longterm capital gains are taxable as long-term capital gains regardless of how
long you have owned your investment. Taxable dividends do not qualify for a
dividends received deduction if you are a corporate shareholder.
 
Each year, you will receive a year-end statement that describes the tax status
of dividends paid to you during the preceding year, including the source of its
investment income by state and the portion of its income that is subject to AMT.
You will receive this statement from the firm where you purchased your fund
shares if you hold your investment in street name; Nuveen will send you this
statement if you hold your shares in registered form.
 
The tax status of your dividends is not affected by whether you reinvest your
dividends or receive them in cash.
 
BUYING OR SELLING SHARES CLOSE TO A RECORD DATE
 
If you purchase fund shares shortly before the record date for a taxable
dividend, this is commonly known as "buying a dividend." The entire dividend you
receive may be taxable to you even though a portion of the dividend effectively
represents a return of your purchase price. Similarly, if you sell or exchange
fund shares shortly before the record date for a tax-exempt dividend, a portion
of the price you receive may be treated as a taxable capital gain even though it
reflects tax-free income earned but not yet distributed by the fund.
 
REDEEMING SHARES HELD LESS THAN SIX MONTHS
 
If you sell or exchange shares that you have owned for less than six months and
you recognized a short-term capital loss when you redeemed your shares, the loss
you can claim will be reduced by the amount of tax-free dividends paid to you on
those shares. Any remaining short-term capital loss will be treated as long-term
capital loss to the extent you also received capital gain dividends on those
shares. You should consult your tax adviser for complete information about these
rules. Please consider the tax consequences carefully when contemplating a
redemption.
 
OTHER IMPORTANT TAX INFORMATION
 
In order to avoid corporate taxation of its earnings and to pay tax-free
dividends, each fund must meet certain I.R.S. requirements that govern the
fund's sources of income, diversification of assets and distribution of earnings
to shareholders. Each fund has met these requirements in the past and intends to
do so in the future. If a fund failed to do so, the fund would be required to
pay corporate taxes on its earnings and all your distributions would be taxable
as ordinary income.
 
 24
<PAGE>   100
 
A fund may be required to withhold 31% of certain of your dividends if you have
not provided the fund with your correct taxpayer identification number (normally
your social security number), or if you are otherwise subject to back-up
withholding.
 
If you receive social security benefits, you should be aware that tax-free
income is taken into account in calculating the amount of these benefits that
may be subject to federal income tax.
 
If you borrow money to buy fund shares, you may not deduct the interest on that
loan. Under I.R.S. rules, fund shares may be treated as having been bought with
borrowed money even if the purchase cannot be traced directly to borrowed money.
 
If you are subject to the alternative minimum tax, a portion of your regular
monthly dividends may be taxable.
 
TAXABLE EQUIVALENT YIELDS
 
The taxable equivalent yield is the current yield you would need to earn on a
taxable investment in order to equal a stated tax-free yield on a municipal
investment. To assist you to more easily compare municipal investments like the
funds with taxable alternative investments, the table below presents the taxable
equivalent yields for a range of hypothetical tax-free yields and tax rates:

PORTFOLIO MANAGERS
 
Overall investment management strategy and operating policies for the funds are
set by the Investment Policy Committee of Nuveen Advisory. The Investment Policy
Committee is comprised of the principal executive officers and portfolio
managers of Nuveen Advisory and meets regularly to review economic conditions,
the outlook for the financial markets in general and the status of the municipal
markets in particular. Day-to-day operation of each fund and the execution of
its specific investment strategies is the responsibility of the designated
portfolio manager described below.
 
Thomas C. Spalding is the portfolio manager for the Municipal Bond Fund. Mr.
Spalding has managed the fund since 1976 and has been a Vice President of Nuveen
Advisory since 1978. Steven J. Krupa is the portfolio manager for the Insured
Fund. Mr. Krupa has managed the fund since 1994 and has been a Vice President of

THE DISTRIBUTOR
 
John Nuveen and Co. Incorporated serves as the selling agent and distributor of
the funds' shares. In this capacity, Nuveen manages the offering of the funds'
shares and is responsible for all sales and promotional activities. In order to
reimburse Nuveen for its costs in connection with these activities, including
compensation paid to authorized dealers, each fund has adopted a distribution
and service plan under Rule 12b-1 of the Investment Company Act of 1940.
 
The plan authorizes each fund to pay Nuveen an annual 0.20% service fee on the
average daily net assets of Class A, B and C shares outstanding. The plan also
authorizes each fund (excluding the Intermediate Municipal Bond Fund and Limited
Term Municipal Bond Fund which do not currently offer Class B shares) to pay
Nuveen an annual 0.75% distribution fee on the average daily net assets of Class
B shares outstanding. The plan also authorizes each fund to pay Nuveen an annual
0.55% (0.35% for the Limited Term Municipal Bond Fund) distribution fee on the
average daily net assets of Class C shares outstanding. In order to help
compensate Nuveen for the sales commission paid to financial advisers at the
time of sale on
 
 26
<PAGE>   102
 
sales of Class B and Class C shares, Nuveen retains the first year's service fee
on sales of Class B shares and all Class B distribution fees; and retains the
first year's service and distribution fees on sales of Class C shares.
Otherwise, Nuveen pays these fees to the broker of record. The statement of
additional information contains a detailed description of the plan and its
provisions.
 
TRANSFER AGENT
 
Each fund has appointed a transfer agent which is responsible for distributing
dividend payments and providing certain bookkeeping, data processing and other
administrative services in connection with the maintenance of shareholder
accounts. Shareholder Services, Inc., P.O. Box 5330, Denver, CO 80217-5330,
currently serves as transfer agent for the Municipal Bond Fund and the Insured
Municipal Bond Fund. Boston Financial, P.O. Box 8509, Boston, MA, 02266-8509,
currently serves as transfer agent for the All-American Fund, the Intermediate
Fund, and the Limited Term Fund. The funds intend to consolidate transfer agent
activities with a single firm in the future.
 
HOW THE FUNDS REPORT PERFORMANCE
 
Each fund may quote its yield and total return in reports to shareholders, sales
literature and advertisements. The funds may also compare their investment
results to various passive indices or other mutual funds with similar investment
objectives. Comparative performance information may include data from Lipper
Analytical Services, Inc., Morningstar, Inc. and other industry publications.
See the statement of additional information for a more detailed discussion. You
may find more information about each fund's performance in its annual report.
Call Nuveen at (800) 621-7227 for a free copy.
 
HOW FUND SHARES ARE PRICED
 
The share price for each class of fund shares, also called its net asset value
(NAV), is calculated every business day as of the close of regular trading on
the New York Stock Exchange (normally 4 p.m. Eastern time). The net asset value
for a class of fund shares is computed by calculating the total value of the
class' portion of the fund's portfolio investments and other assets, subtracting
any liabilities or other debts, and dividing by the total number of its shares
outstanding.
 
The prices of municipal bonds in each fund's investment portfolio are provided
by a pricing service approved and supervised by the fund's Board of Trustees.
When price quotes are not readily available (which is usually the case for
municipal securities), the pricing service establishes fair market value based
on yields or prices of municipal bonds of comparable quality, type of issue,
coupon, maturity and rating, indications of value from securities dealers and
general market conditions.
 
ORGANIZATION
 
The Trust is an open-end diversified investment company under the Investment
Company Act of 1940, consisting of multiple funds. The shares of each fund are
divided into classes. Each class of shares represents an interest in the same
portfolio of investments and the shares of each class have equal rights as to
voting, redemption, dividends and liquidation. However, each class bears
different sales charges and service fees. B shares convert to A shares after 8
years.
 
Class C shares of the Municipal Bond Fund and the Insured Municipal Bond Fund
purchased before February 1, 1997 convert to A shares six years after purchase,
but only if you request conversion. You must submit your request to SSI no later
than the last business day of the 71st month following the month in which you
purchased your shares.
 
The funds are not required to and do not intend to hold annual meetings.
Shareholders owning ten percent or more of a fund's outstanding shares may call
a special meeting for any purpose, including to elect or remove trustees or to
change fundamental policies.

                      PROPECTUS DATED SEPTEMBER 26, 1997


                         ----------------------------

                     NUVEEN FLAGSHIP MULTISTATE TRUST III
                 NUVEEN FLAGSHIP ALABAMA MUNICIPAL BOND FUND


              NUVEEN FLAGSHIP SOUTH CAROLINA MUNICIPAL BOND FUND


                         ----------------------------


The Trustees of the Nuveen Flagship Multistate Trust III have approved a
tax-free reorganization of each of the Nuveen Flagship Alabama Municipal Bond
Fund (the "Alabama Fund") and the Nuveen Flagship South Carolina Municipal Bond
Fund (the "South Carolina Find"), as described below.  The Alabama Fund and the
South Carolina Fund are closed to new investors effective May 8, 1998.  On and
after May 8, 1998 only shareholders with existing accounts may continue to make
additional purchases and to reinvest dividends into existing accounts.

Under the terms of the reorganizations, each fund will transfer all of its
assets and liabilities to the Nuveen Flagship All-American Municipal Bond Fund
(the "Acquiring Fund"), a series of Nuveen Flagship Municipal Trust, in a
tax-free exchange for an equal value of shares of the Acquiring Fund.  The
Acquiring Fund is a municipal bond fund whose investment objective is to
provide as high a level of current interest income exempt from regular federal
income taxes as is consistent with preservation of capital.  Unlike the Alabama
or the South Carolina Funds, the Acquiring Fund does not invest primarily in
Alabama or South Carolina municipal bonds, respectively.  As with any mutual
fund, there is no assurance that the Acquiring Fund will meet its investment
objective.  Each reorganization is subject to certain regulatory approvals
and the respective approval of the Alabama Fund's and the South Carolina Fund's
Shareholders. A meeting of shareholders for the Alabama and the South
Carolina Funds has been called for August 13, 1998. Further information
regarding the proposed reorganization and the shareholder meetings will be
contained in a proxy statement that is scheduled to be mailed in June, 1998.

Class A total returns reflect actual performance for all periods; Classes B, C
and R total returns reflect actual performance for periods since class inception
(see "Financial Highlights" for dates) and Class A performance for periods prior
to class inception, adjusted for the differences in sales charges (and for Class
B and C, fees) between the classes. Class B total returns assume an ongoing
investment and do not reflect the imposition of the CDSC; your returns for the 1
year and since inception periods would be lower if you redeemed at the end of
those periods. See Overview of Fund Operating Expenses and Shareholder
Transaction Expenses.
 
The fund assumes investment risk in pursuit of its investment objective, chiefly
in the form of interest rate risk and credit risk. The fund limits this risk by
purchasing only certain types and maturities of municipal bonds and by
diversifying its investment portfolio geographically and by industry. See Risk
Reduction Strategies for further information.

+ Annualized.
 
++ Information included prior to the year ending May 31, 1997, reflects the
financial highlights of Flagship Alabama.
 
(a) Total returns are calculated on net asset value without any sales charge.
 
(b) After waiver of certain management fees or reimbursement of expenses, if
applicable, by Nuveen Advisory or its predecessor, Flagship Financial.
 
(c) From commencement of class operations as noted.
 
NOTES:
 
(1) The Class A sales charge may be reduced or waived based on the amount of
purchase or for certain eligible categories of investors. A CDSC of 1% is
imposed on redemptions of certain purchases of $1 million or more within 18
months of purchase. See "How to Select a Purchase Option."
 
(2) CDSC declines to 0% at the end of six years.
 
(3) Imposed only on redemptions within 12 months of purchase.
 
(4) Effective February 1, 1997, the fund eliminated the 0.20% distribution fee
on Class A shares and reduced the distribution fee on Class C shares from 0.75%
to 0.55%. Long-term holders of Class B and C shares may pay more in distribution
fees and CDSCs than the maximum initial sales charge permitted under National
Association of Securities Dealers (NASD) Rules of Fair Practice. The
waiver/reimbursement levels shown reflect Nuveen's current undertaking, made in
connection with its acquisition of Flagship Resources as described in "Fund
Service Providers--Investment Adviser," to continue Flagship's general
dividend-setting practices.
 
(5) The expenses shown assume that you redeem your shares at the end of each
holding period. Class B shares convert to Class A shares after eight years. If
instead you redeemed your shares immediately prior to the end of each holding
period, your expenses would be higher. If you did not redeem Class B shares at
the end of each holding period, your expenses would have been $12 for the one
year period, $36 for the three year period, $63 for the five year period, and
$118 for the ten year period. This example does not represent past or future
expenses; actual expenses may be higher or lower.

Class A total returns reflect actual performance for all periods; Classes B, C
and R total returns reflect actual performance for periods since class inception
(see "Financial Highlights" for dates), and Class A performance for periods
prior to class inception, adjusted for the differences in sales charges (and for
Class B and C, fees) between the classes. Class B total returns assume an
ongoing investment and do not reflect the imposition of the CDSC; your returns
for the 1 year and 5 year periods would be lower if you redeemed at the end of
those periods. See Overview of Fund Operating Expenses and Shareholder
Transaction Expenses.
 
The fund assumes investment risk in pursuit of its investment objective, chiefly
in the form of interest rate risk and credit risk. The fund limits this risk by
purchasing only certain types and maturities of municipal bonds and by
diversifying its investment portfolio geographically and by industry. See Risk
Reduction Strategies for further information.

 + Annualized.
 
++ Information included prior to the year ending May 31, 1997, reflects the
financial highlights of Flagship Georgia.
 
(a) Total returns are calculated on net asset value without any sales charge.
 
(b) After waiver of certain management fees or reimbursement of expenses, if
applicable, by Nuveen Advisory or its predecessor, Flagship Financial.
 
(c) From commencement of class operations as noted.
 
NOTES:
 
(1) The Class A sales charge may be reduced or waived based on the amount of
purchase or for certain eligible categories of investors. A CDSC of 1% is
imposed on redemptions of certain purchases of $1 million or more within 18
months of purchase. See "How to Select a Purchase Option."
 
(2) CDSC declines to 0% at the end of six years.
 
(3) Imposed only on redemptions within 12 months of purchase.
 
(4) Effective February 1, 1997, the fund eliminated the 0.20% distribution fee
on Class A Shares and reduced the distribution fee on Class C shares from 0.75%
to 0.55%. Long-term holders of Class B and C shares may pay more in distribution
fees and CDSCs than the maximum initial sales charge permitted under National
Association of Securities Dealers (NASD) Rules of Fair Practice. The
waiver/reimbursement levels shown reflect Nuveen's current undertaking, made in
connection with its acquisition of Flagship Resources as described in "Fund
Service Providers--Investment Adviser," to continue Flagship's general
dividend-setting practices.
 
(5) The expenses shown assume that you redeem your shares at the end of each
holding period. Class B shares convert to Class A shares after eight years. If
instead you redeemed your shares immediately prior to the end of each holding
period, your expenses would be higher. If you did not redeem Class B shares at
the end of each holding period, your expenses would have been $15 for the one
year period, $46 for the three year period, $79 for the five year period, and
$152 for the ten year period. This example does not represent past or future
expenses; actual expenses may be higher or lower.

Class A total returns reflect actual performance for all periods; Classes B, C
and R total returns reflect actual performance for periods since class inception
(see "Financial Highlights" for dates), and Class A performance for periods
prior to class inception, adjusted for the differences in sales charges (and for
Class B and C, fees) between the classes. Class B total returns assume an
ongoing investment and do not reflect the imposition of the CDSC; your returns
for the 1 year and 5 year periods would be lower if you redeemed at the end of
those periods. See Overview of Fund Operating Expenses and Shareholder
Transaction Expenses.
 
The fund assumes investment risk in pursuit of its investment objective, chiefly
in the form of interest rate risk and credit risk. The fund limits this risk by
purchasing only certain types and maturities of municipal bonds and by
diversifying its investment portfolio geographically and by industry. See Risk
Reduction Strategies for further information.

+ Annualized.
 
++ Information included prior to the year ending May 31, 1997, reflects the
financial highlights of Flagship Louisiana.
 
+++ Amount shown includes a distribution in excess of capital gains of $.01 per
share.
 
(a) Total returns are calculated on net asset value without any sales charge.
 
(b) After waiver of certain management fees or reimbursement of expenses, if
applicable, by Nuveen Advisory or its predecessor, Flagship Financial.
 
(c) From commencement of class operations as noted.
 
NOTES:
 
(1) The Class A sales charge may be reduced or waived based on the amount of
purchase or for certain eligible categories of investors. A CDSC of 1% is
imposed on redemptions of certain purchases of $1 million or more within 18
months of purchase. See "How to Select a Purchase Option."
 
(2) CDSC declines to 0% at the end of six years.
 
(3) Imposed only on redemptions within 12 months of purchase.
 
(4) Effective February 1, 1997, the fund eliminated the 0.20% distribution fee
for Class A shares and reduced the distribution fee on Class C shares from 0.75%
to 0.55%. Long-term holders of Class B and C shares may pay more in distribution
fees and CDSCs than the maximum initial sales charge permitted under National
Association of Securities Dealers (NASD) Rules of Fair Practice. The
waiver/reimbursement levels shown reflect Nuveen's current undertaking, made in
connection with its acquisition of Flagship Resources as described in "Fund
Service Providers--Investment Adviser," to continue Flagship's general
dividend-setting practices.
 
(5) The expenses shown assume that you redeem your shares at the end of each
holding period. Class B shares convert to Class A shares after eight years. If
instead you redeemed your shares immediately prior to the end of each holding
period, your expenses would be higher. If you did not redeem Class B shares at
the end of each holding period, your expenses would have been $16 for the one
year period, $49 for the three year period, $84 for the five year period, and
$164 for the ten year period. This example does not represent past or future
expenses; actual expenses may be higher or lower.

Class A total returns reflect actual performance for all periods; Classes B, C
and R total returns reflect actual performance for periods since class inception
(see "Financial Highlights" for dates), and Class A performance for periods
prior to class inception, adjusted for the differences in sales charges (and for
Class B and C, fees) between the classes. Class B total returns assume an
ongoing investment and do not reflect the imposition of the CDSC; your returns
for the 1 year and 5 year periods would be lower if you redeemed at the end of
those periods. See Overview of Fund Operating Expenses and Shareholder
Transaction Expenses.
 
The fund assumes investment risk in pursuit of its investment objective, chiefly
in the form of interest rate risk and credit risk. The fund limits this risk by
purchasing only certain types and maturities of municipal bonds and by
diversifying its investment portfolio geographically and by industry. See Risk
Reduction Strategies for further information.

+ Annualized.
 
++ Information included prior to the year ending May 31, 1997, reflects the
   financial highlights of Flagship North Carolina.
 
(a) Total returns are calculated on net asset value without any sales charge.
 
(b) After waiver of certain management fees or reimbursement of expenses, if
    applicable, by Nuveen Advisory or its predecessor, Flagship Financial.
 
(c) From commencement of class operations as noted.
 
NOTES:
 
(1) The Class A sales charge may be reduced or waived based on the amount of
purchase or for certain eligible categories of investors. A CDSC of 1% is
imposed on redemptions of certain purchases of $1 million or more within 18
months of purchase. See "How to Select a Purchase Option."
 
(2) CDSC declines to 0% at the end of six years.
 
(3) Imposed only on redemptions within 12 months of purchase.
 
(4) Effective February 1, 1997, the fund eliminated the 0.20% distribution fee
for Class A shares and reduced the distribution fee on Class C shares from 0.75%
to 0.55%. Long-term holders of Class B and C shares may pay more in distribution
fees and CDSCs than the maximum initial sales charge permitted under National
Association of Securities Dealers (NASD) Rules of Fair Practice. The
waiver/reimbursement levels shown reflect Nuveen's current undertaking, made in
connection with its acquisition of Flagship Resources as described in "Fund
Service Providers--Investment Adviser," to continue Flagship's general
dividend-setting practices.
 
(5) The expenses shown assume that you redeem your shares at the end of each
holding period. Class B shares convert to Class A shares after eight years. If
instead you redeemed your shares immediately prior to the end of each holding
period, your expenses would be higher. If you did not redeem Class B shares at
the end of each holding period, your expenses would have been $16 for the one
year period, $51 for the three year period, $88 for the five year period, and
$171 for the ten year period. This example does not represent past or future
expenses; actual expenses may be higher or lower.

Class A total returns reflect actual performance for all periods; Classes B, C
and R total returns reflect actual performance for periods since class inception
(see "Financial Highlights" for dates), and Class A performance for periods
prior to class inception, adjusted for the differences in sales charges (and for
Class B and C, fees) between the classes. Class B total returns assume an
ongoing investment and do not reflect the imposition of the CDSC; your returns
for the 1 year and since inception periods would be lower if you redeemed at the
end of those periods. See Overview of Fund Operating Expenses and Shareholder
Transaction Expenses.
 
The fund assumes investment risk in pursuit of its investment objective, chiefly
in the form of interest rate risk and credit risk. The fund limits this risk by
purchasing only certain types and maturities of municipal bonds and by
diversifying its investment portfolio geographically and by industry. See Risk
Reduction Strategies for further information.

+ Annualized.
 
++ Information included prior to the year ending May 31, 1997, reflects the
   financial highlights of Flagship South Carolina.
 
(a) Total returns are calculated on net asset value without any sales charge.
 
(b) After waiver of certain management fees or reimbursement of expenses, if
    applicable, by Nuveen Advisory or its predecessor, Flagship Financial.
 
(c) From commencement of class operations as noted.
 
NOTES:
 
(1) The Class A sales charge may be reduced or waived based on the amount of
purchase or for certain eligible categories of investors. A CDSC of 1% is
imposed on redemptions of certain purchases of $1 million or more within 18
months of purchase. See "How to Select a Purchase Option."
 
(2) CDSC declines to 0% at the end of six years.
 
(3) Imposed only on redemptions within 12 months of purchase.
 
(4) Effective February 1, 1997, the fund eliminated the 0.20% distribution fee
on Class A shares and reduced the distribution fee on Class C shares from 0.75%
to 0.55%. Long-term holders of Class B and C shares may pay more in distribution
fees and CDSCs than the maximum initial sales charge permitted under National
Association of Securities Dealers (NASD) Rules of Fair Practice. The
waiver/reimbursement levels shown reflect Nuveen's current undertaking, made in
connection with its acquisition of Flagship Resources as described in "Fund
Service Providers--Investment Adviser," to continue Flagship's general
dividend-setting practices.
 
(5) The expenses shown assume that you redeem your shares at the end of each
holding period. Class B shares convert to Class A shares after eight years. If
instead you redeemed your shares immediately prior to the end of each holding
period, your expenses would be higher. If you did not redeem Class B shares at
the end of each holding period, your expenses would have been $14 for the one
year period, $42 for the three year period, $73 for the five year period, and
$141 for the ten year period. This example does not represent past or future
expenses; actual expenses may be higher or lower.

Class A total returns reflect actual performance for all periods; Classes B, C
and R total returns reflect actual performance for periods since class inception
(see "Financial Highlights" for dates), and Class A performance for periods
prior to class inception, adjusted for the differences in sales charges (and for
Class B and C, fees) between the classes. Class B total returns assume an
ongoing investment and do not reflect the imposition of the CDSC; your returns
for the 1 year and 5 year periods would be lower if you redeemed at the end of
those periods. See Overview of Fund Operating Expenses and Shareholder
Transaction Expenses.
 
The fund assumes investment risk in pursuit of its investment objective, chiefly
in the form of interest rate risk and credit risk. The fund limits this risk by
purchasing only certain types and maturities of municipal bonds and by
diversifying its investment portfolio geographically and by industry. See Risk
Reduction Strategies for further information.

+ Annualized.
 
++ Information included prior to the year ending May 31, 1997, reflects the
financial highlights of Flagship Tennessee.
 
(a) Total returns are calculated on net asset value without any sales charge.
 
(b) After waiver of certain management fees or reimbursement of expenses, if
applicable, by Nuveen Advisory or its predecessor, Flagship Financial.
 
(c) From commencement of class operations as noted.
 
NOTES:
 
(1) The Class A sales charge may be reduced or waived based on the amount of
purchase or for certain eligible categories of investors. A CDSC of 1% is
imposed on redemptions of certain purchases of $1 million or more within 18
months of purchase. See "How to Select a Purchase Option."
 
(2) CDSC declines to 0% at the end of six years.
 
(3) Imposed only on redemptions within 12 months of purchase.
 
(4) Effective February 1, 1997, the fund eliminated the 0.20% distribution fee
on Class A shares and reduced the distribution fee on Class C shares from 0.75%
to 0.55%. Long-term holders of Class B and C shares may pay more in distribution
fees and CDSCs than the maximum initial sales charge permitted under National
Association of Securities Dealers (NASD) Rules of Fair Practice. The
waiver/reimbursement levels shown reflect Nuveen's current undertaking, made in
connection with its acquisition of Flagship Resources as described in "Fund
Service Providers--Investment Adviser," to continue Flagship's general
dividend-setting practices.
 
(5) The expenses shown assume that you redeem your shares at the end of each
holding period. Class B shares convert to Class A shares after eight years. If
instead you redeemed your shares immediately prior to the end of each holding
period, your expenses would be higher. If you did not redeem Class B shares at
the end of each holding period, your expenses would have been $16 for the one
year period, $49 for the three year period, $84 for the five year period, and
$164 for the ten year period. This example does not represent past or future
expenses; actual expenses may be higher or lower.

FUND STRATEGIES
 
INVESTMENT OBJECTIVE
 
The investment objective of each fund is to provide you with as high a level of
current interest income exempt from regular federal, state and, in some cases,
local income taxes as is consistent with preservation of capital. There is no
assurance that the funds will achieve their investment objective.
 
INVESTOR SUITABILITY
 
The funds are a suitable investment for tax-conscious investors seeking to:
 
- - Earn regular monthly tax-free dividends;
 
- - Preserve investment capital over time;
 
- - Reduce taxes on investment income;
 
- - Set aside money systematically for retirement, estate planning or college
  funding.
 
The funds are not a suitable investment for individuals seeking to:
 
- - Pursue an aggressive, high-growth investment strategy;
 
- - Invest through an IRA or 401k plan;
 
- - Avoid fluctuations in share price.
 
HOW THE FUNDS SELECT INVESTMENTS
 
TAX-FREE MUNICIPAL BONDS
 
The funds invest substantially all of their assets (at least 80%) in municipal
bonds that pay interest that is exempt from regular federal, state and, in some
cases, local income taxes. Income from these bonds may be subject to the federal
alternative minimum tax.
 
Municipal bonds are either general obligation or revenue bonds and typically are
issued to finance public projects (such as roads or public buildings), to pay
general operating expenses, or to refinance outstanding debt. Municipal bonds
may also be issued for private activities, such as housing, medical and
educational facility construction, or for privately owned industrial development
and pollution control projects. General obligation bonds are backed by the full
faith and credit, or taxing authority, of the issuer and may be repaid from any
revenue source; revenue bonds may be repaid only from the revenues of a specific
facility or source.
 
FOCUS ON QUALITY MUNICIPAL BONDS
 
The funds purchase only quality municipal bonds that are either rated investment
grade (AAA/Aaa to BBB/Baa) by independent ratings agencies at the time of
purchase or are non-rated but judged to be investment grade by the funds'
investment adviser. If suitable municipal bonds from a specific state are not
available at attractive prices and yields, a fund may invest in municipal bonds
of U.S. territories (such as Puerto Rico and Guam) which are exempt from regular
federal, state, and local income taxes.
 
The funds may purchase municipal bonds that represent lease obligations. These
carry special risks because the issuer of the bonds may not be obligated to
appropriate money annually to make payments under the lease. In order to reduce
this risk, the funds will only purchase leases where the issuer has a strong
incentive to continue making appropriations until maturity.
 
Bond ratings are furnished by Standard & Poor's Corporation, Fitch Investors
Services, and Moody's Investors Services. The ratings BBB and Baa are not
identical -- S&P and Fitch consider bonds rated BBB to have adequate capacity to
pay principal and interest; Moody's considers bonds rated Baa to have some
speculative characteristics. Bond ratings represent the opinions of the ratings
agencies; they are not absolute standards of quality.
 
VALUE INVESTING STRATEGY
 
The funds' investment adviser uses a value-oriented strategy and looks for
higher-yielding and undervalued municipal bonds that offer above-average total
return potential. The adviser emphasizes fundamental research and selects
municipal bonds on the basis of its evaluation of each bond's relative value in
terms of current yield, price, credit quality and future prospects. The adviser
then monitors each fund's portfolio to assure that municipal bonds purchased
continue to represent over time, in its opinion, the best values available.
 
 19
<PAGE>   127
 
PORTFOLIO MATURITY
 
Each fund purchases municipal bonds with different maturities in pursuit of its
investment objective, but maintains under normal market conditions an investment
portfolio with an overall weighted average maturity within a defined range. All
of the funds described in this prospectus are long-term funds and normally
maintain a weighted average portfolio maturity of 15 to 30 years. See "Defensive
Investment Strategies" below for further information.
 
PORTFOLIO TURNOVER
 
A fund buys and sells portfolio securities in the normal course of its
investment activities. The proportion of the fund's investment portfolio that is
sold and replaced with new securities during a year is known as the fund's
portfolio turnover rate. The funds intend to keep portfolio turnover relatively
low in order to reduce trading costs and the realization of taxable capital
gains. Each fund, however, may make limited short-term trades to take advantage
of market opportunities or reduce market risk.
 
DELAYED DELIVERY TRANSACTIONS
 
Each fund may buy or sell bonds on a when-issued or delayed delivery basis,
making payment or taking delivery at a later date, normally within 15 to 45 days
of the trade date. This type of transaction may involve an element of risk
because no interest accrues on the bonds prior to settlement and, since
securities are subject to market fluctuation, the value of the bonds at time of
delivery may be less (or more) than cost.
 
RISK REDUCTION STRATEGIES
 
In pursuit of its investment objective, each fund assumes investment risk,
chiefly in the form of interest rate and credit risk. Interest rate risk is the
risk that changes in market interest rates will affect the value of a fund's
investment portfolio. In general, the value of a municipal bond falls when
interest rates rise, and increases when interest rates fall. Credit risk is the
risk that an issuer of a municipal bond is unable to meet its obligation to make
interest and principal payments. In general, lower rated municipal bonds are
perceived to carry a greater degree of risk in the issuer's ability to make
interest and principal payments. Municipal bonds with longer maturities
(durations) or lower ratings generally provide higher current income, but are
subject to greater price fluctuation due to changes in market conditions than
bonds with shorter maturities or higher ratings, respectively.
 
Because the funds primarily purchase municipal bonds from a specific state, each
fund also bears investment risk from the economic, political or regulatory
changes that could adversely affect municipal bond issuers in that state and
therefore the value of the fund's investment portfolio. These risks may be
greater for the Alabama, Georgia, Louisiana, North Carolina and South Carolina
Funds, which as "non-diversified" funds may concentrate their investments in
municipal bonds of certain issuers to a greater extent than the Tennessee Fund
described in this prospectus, which is a diversified fund.
 
The funds limit your investment risk generally by restricting the types and
maturities of municipal bonds they purchase, and by diversifying their
investment portfolios across different industry sectors. The funds should be
considered long-term investments and may not be suitable for investors with
shortterm investment horizons.
 
INVESTMENT LIMITATIONS
 
The funds have adopted certain investment limitations (based on total fund
assets) designed to limit your investment risk and maintain portfolio
diversification. Each fund may not have more than:
 
- - 25% in any one industry sector, such as electric utilities or health care; and
 
- - 10% in borrowings (33% if used to meet redemptions).
 
As a diversified fund, the Tennessee Fund also may not have more than:
 
- - 5% in securities of any one issuer (except U.S. government securities or for
  25% of each fund's assets).
 
DEFENSIVE INVESTMENT STRATEGIES
 
Each fund may invest in high quality short-term municipal securities in order to
reduce risk and preserve capital. Under normal market conditions, each fund may
invest only up to 20% of net assets in short-term municipal securities that are
exempt from regular federal income tax, although the funds may invest up to 100%
as a temporary defensive measure in response to adverse market conditions.
During temporary defensive periods, the weighted average maturity of a fund's
investment portfolio may fall below the defined range described above under
"Portfolio Maturity."
 
 20
<PAGE>   128
 
If suitable short-term municipal investments are not reasonably available, the
funds may invest in short-term taxable securities that are rated Aaa or AAA, by
Moody's or S&P, respectively, or issued by the U.S. government, and that have a
maturity of one year or less or have a variable interest rate.
 
Each fund may also use various investment strategies designed to limit the risk
of bond price fluctuations and to preserve capital. These hedging strategies
include using financial futures contracts, options on financial futures, or
options based on either an index of long-term tax-free securities or on debt
securities whose prices, in the opinion of the funds' investment adviser,
correlate with the prices of the funds' investments. The funds, however, have no
present intent to use these strategies.
 
FUNDAMENTAL INVESTMENT POLICIES
 
Each fund's investment objective as well as the policies described above in
"Focus on Quality Municipal Bonds" and "Risk Reduction Strategies" are
fundamental and may not be changed without the approval of a majority of the
shareholders of each fund.
 
INVESTING IN THE FUNDS
 
HOW TO BUY FUND SHARES
 
You may open an account with $3,000 per fund share class and make additional
investments at any time with as little as $50. Reinvestment of Nuveen unit trust
distributions have no purchase minimums. Purchases through sponsors of fee-based
programs meeting certain criteria, as described in the statement of additional
information, may be eligible for lower minimums. The share price you pay will
depend on when Nuveen receives your order: orders received before the close of
regular trading on the New York Stock Exchange (normally 4:00 p.m. Eastern time)
will receive that day's share price; otherwise you will receive the next
business day's share price.
 
BUYING SHARES THROUGH A FINANCIAL ADVISER
 
You may buy fund shares through your financial adviser, who can handle all the
details for you, including establishing an account with Nuveen. Financial
advisers can also help you review your financial needs and formulate long-term
investment goals and objectives. In addition, financial advisers generally can
help you develop a customized financial plan, select investments, and monitor
and review your portfolio on an ongoing basis to assure your investments
continue to meet your needs as circumstances change.
 
Financial advisers are usually paid either from fund sales charges and fees or
by charging you a separate fee in lieu of a sales charge for ongoing investment
advice and services.
 
If you do not have a financial adviser, call (800) 621-7227 and Nuveen can refer
you to one in your area.
 
BUYING SHARES BY MAIL
 
You may also open an account and purchase shares by mail by completing the
enclosed Nuveen application and mailing it along with your check (payable to the
appropriate fund) to the address listed under "How to Contact Nuveen." Sales
charges are not waived when you buy shares by mail.
 
Each fund reserves the right to reject any purchase order and waive or increase
minimum investment requirements. The funds also reserve the right to suspend the
issuance of shares at any time; any suspension, however, will not affect your
ability to redeem shares.
 
HOW TO SELECT A PURCHASE OPTION
 
The funds offer you a variety of flexible options when buying shares. Whether
you typically work with a financial adviser on a commission or a fee basis or
prefer to work on a more self-directed basis, you can purchase shares in the way
that is most suited to your individual circumstances and investment needs. Each
of the four available ways to purchase fund shares is called a class of shares:
Class A, Class B, Class C and Class R. While each of these classes features
different sales charges, on-going fees and eligibility requirements, each
entitles you to a share of the same portfolio of municipal bonds.
 
Selecting the class of shares which is most appropriate for you will depend on a
variety of factors. You should weigh carefully whether you and your financial
adviser work on a commission or fee basis, the types of services that you will
receive, the amount you intend to buy, how long you plan to own your investment
and whether or not you will reinvest dividends. If you compensate your financial
adviser directly, you should consider the fees your financial adviser charges
for investment advice or handling your trades in addition to any sales charges
and fees imposed by the funds. Please refer to your financial adviser's sales
material for further information. Each class of shares is described in more
detail below and under "Fund Service Providers -- The Distributor." Your
financial adviser can explain each option and help you determine which is most
appropriate for you, or you can call (800) 621-7227.
 
 21
<PAGE>   129
 
BUYING CLASS A SHARES
 
You may buy Class A shares at their public offering price on the day of
purchase. The price you pay will equal the Class A NAV (net asset value) plus a
sales charge based upon the amount of your purchase. Class A shares also bear a
0.20% annual service fee which compensates your financial adviser for providing
you with ongoing service.
 
The following Class A sales charges and commissions apply to all funds described
in this prospectus:

(1) Nuveen pays authorized dealers a commission equal to the sum of 1% of the
    first $2.5 million, plus 0.50% of the next $2.5 million, plus 0.25% of any
    amount over $5 million. Unless the authorized dealer waived the commission,
    you may be assessed a contingent deferred sales charge (CDSC) of 1% if you
    redeem any of your shares within 18 months of purchase. The CDSC is
    calculated on the lower of your purchase price or redemption proceeds.
 
Nuveen periodically undertakes sales promotion programs with authorized dealers
and may pay them the full applicable sales charge as a commission. In addition,
Nuveen may provide support to authorized dealers in connection with sales
meetings, seminars, prospecting seminars and other events at which Nuveen
presents its products and services. Under certain circumstances, Nuveen may also
make ongoing payments to authorized dealers to facilitate the marketing and
administration of new and existing shareholder accounts, including payments for
advertising. The statement of additional information contains further
information about these programs.
 
OTHER SALES CHARGE DISCOUNTS
 
Nuveen offers a number of programs that enable you to reduce or eliminate the
sales charge on Class A shares:
 
SALES CHARGE REDUCTIONS
 
- - Rights of Accumulation
 
- - Letter of Intent
 
- - Group Purchase
 
SALES CHARGE WAIVERS
 
- - Nuveen Unit Trust Reinvestment
 
- - Purchases using Redemptions from Unrelated Funds
 
- - Fee-Based Programs
 
- - Bank Trust Departments
 
- - Certain Employees of Nuveen or Authorized Dealers
 
Please refer to the statement of additional information for detailed
descriptions of these programs. Further information on these programs is also
available through your financial adviser or by calling (800) 621-7227. Your
financial adviser can also provide and help you prepare the necessary
application forms. You or your financial adviser are responsible for notifying
Nuveen about your eligibility for any sales charge reduction or waiver at the
time of each purchase.
 
The funds may modify or discontinue these programs at any time upon written
notice to shareholders.
 
BUYING CLASS B SHARES
 
You may buy Class B shares at their public offering price on the day of
purchase. The price you pay will equal the Class B NAV. There is no initial
sales charge, but Class B shares bear a 0.20% annual service fee which
compensates your financial
 
 22
<PAGE>   130
 
adviser for providing you with ongoing service, and a 0.75% annual distribution
fee which compensates Nuveen for paying your financial adviser a 4% commission
at the time of purchase.
 
Class B shares convert automatically to Class A shares eight years after
purchase. Class B shares will convert only if the fund is assured that the
conversion does not generate tax consequences for investors, based upon the
opinion of outside counsel or the written assurance of the IRS.
 
CLASS B CONTINGENT DEFERRED SALES CHARGE
 
If you redeem Class B shares within six years of purchase, you will be assessed
a contingent deferred sales charge (CDSC) based upon the following schedule:

The CDSC is calculated on the lower of your purchase price or redemption
proceeds.
 
BUYING CLASS C SHARES
 
You may buy Class C shares at their public offering price on the day of
purchase. The price you pay will equal the Class C NAV. There is no initial
sales charge, but Class C shares bear a 0.20% annual service fee which
compensates your financial adviser for providing you with ongoing service, and a
0.55% annual distribution fee which compensates Nuveen for paying your financial
adviser for the sale, including a 1% commission at the time of sale.
 
If you redeem your Class C shares within one year of purchase, you may be
assessed a CDSC of 1%. The CDSC is calculated on the lower of your purchase
price or redemption proceeds.
 
BUYING CLASS R SHARES
 
Under limited circumstances, you may purchase Class R shares at their net asset
value on the day of purchase. In order to qualify, you must be eligible under
one of the programs described under "Other Sales Charge Discounts" above to
purchase Class A shares without a sales charge (excluding Unit Trust
reinvestment) or meet certain other purchase size criteria. Please refer to the
statement of additional information for further information. There are no sales
charges or ongoing fees. Class R shares have lower ongoing expenses than Class A
shares.
 
HOW TO SELL FUND SHARES
 
You may use one of the methods described below to redeem your shares on any day
the New York Stock Exchange is open. You will receive the share price next
determined after Nuveen has received your redemption request in good order. Your
redemption request must be received before the close of trading of the New York
Stock Exchange (normally 4 p.m. Eastern time) for you to receive that day's
price. The funds do not charge any redemption fees, although you will be
assessed a CDSC were applicable.
 
SELLING SHARES THROUGH YOUR FINANCIAL ADVISER
 
You may sell fund shares by contacting your financial adviser who can provide
and help you prepare all the necessary documentation. Your financial adviser may
charge you for this service.
 
SELLING SHARES BY TELEPHONE
 
Unless you have declined telephone redemption privileges, you may sell fund
shares by calling (800) 621-7227. Your redemption must not exceed $50,000 and
you may not redeem by telephone shares held in certificate form. Checks will be
issued only to the shareholder on record and mailed to the address on record. If
you have established electronic funds transfer privileges on your account, you
may have redemption proceeds transferred electronically to your bank account; if
you are redeeming $1,000 or more, you may expedite your request by having your
redemption proceeds wired directly into your bank account. See "Fund Direct --
Electronic Funds Transfer" below.
 
Nuveen, the transfer agent, or the fund will be liable for losses resulting from
unauthorized telephone redemptions only if they do not follow reasonable
procedures designed to verify the identity of the caller. You should immediately
verify your trade confirmations when you receive them.
 
 23
<PAGE>   131
 
SELLING SHARES BY MAIL
 
You may sell fund shares by mail by sending a written request to Nuveen at the
address listed below under "How to Contact Nuveen." Your request must include
the following information:
 
- - The fund's name;
 
- - Your name and account number;
 
- - The dollar or share amount you wish to redeem;
 
- - The signature of each owner exactly as it appears on the account;
 
- - The name of the person you want your redemption proceeds paid to, if other
  than to the shareholder of record;
 
- - The address you want your redemption proceeds sent to, if other than the
  address of record;
 
- - Any certificates you have for the shares; and
 
- - Any required signature guarantees.
 
Signatures must be guaranteed if you are redeeming more than $50,000, you want
the check payable to someone other than the shareholder on record, or you want
the check sent to another address (or the address on record has been changed
within the last 60 days). Signature guarantees must be obtained from a bank,
brokerage firm or other financial intermediary that is a member of an approved
Medallion Guarantee Program or that is otherwise approved by the fund. A notary
public cannot provide a signature guarantee.
 
Unless other arrangements are made, checks will be sent to your address on
record. Checks will normally be mailed within one business day, but in no event
more than seven days from receipt of your redemption request. If any shares were
purchased less than 15 days prior to your request, the fund will not mail your
redemption proceeds until the check for your purchase has cleared, which may
take up to 15 days.
 
Each fund may suspend redemptions or delay payment on redemptions for more than
seven days (three days for street name accounts) in certain extraordinary
circumstances as described in the statement of additional information.
 
OPERATION OF THE CDSC
 
When you redeem Class A, Class B, or Class C shares subject to a CDSC, the fund
will first redeem any shares that are not subject to a CDSC or that represent an
increase in the value of your fund account due to capital appreciation, and then
redeem the shares you have owned for the longest period of time, unless you ask
the fund to redeem your shares in a different order. No CDSC is imposed on
shares you buy through the reinvestment of dividends and capital gains. The
holding period is calculated on a monthly basis and begins on the first day of
the month in which you buy shares. When you redeem shares subject to a CDSC, the
CDSC is calculated on the lower of your purchase price or redemption proceeds,
deducted from your redemption proceeds, and paid to Nuveen. The CDSC may be
waived under certain special circumstances as described in the statement of
additional information.
 
ACCOUNT MINIMUMS
 
From time to time, the funds may establish minimum account size requirements.
The funds reserve the right to liquidate your account upon 30 days written
notice if the value of your account falls below an established minimum. The
funds presently have set a minimum balance of $100 unless you have an active
unit trust reinvestment account. You will not be assessed a CDSC on an
involuntary redemption.
 
EXCHANGING SHARES
 
You may exchange fund shares at any time for the same class of shares in another
Nuveen national or state mutual fund. You may exchange fund shares by calling
(800) 621-7227 or by mailing your written request to Nuveen at the address
listed under "How to Contact Nuveen."
 
You must have owned your fund shares for at least 15 days and your exchange must
meet the minimum purchase requirements of the fund into which you are
exchanging. No CDSC will be assessed on an exchange, and the holding period of
your investment will be carried over to the new fund for purposes of determining
any future CDSC. You may not exchange Class B shares for shares of a Nuveen
money market fund.
 
Because an exchange is treated for tax purposes as the concurrent sale and
purchase of fund shares, you should consult your tax adviser about the tax
consequences of any contemplated exchange. Each fund reserves the right to limit
or terminate exchange privileges if it believes doing so is in the best
interests of fund shareholders.
 
 24
<PAGE>   132
 
RESTRICTIONS ON MARKET TIMING
 
The exchange privilege is not intended to permit you to use a fund for shortterm
trading. Excessive exchange activity may interfere with portfolio management,
raise fund operating expenses or otherwise have an adverse effect on fund
shareholders. In order to limit excessive exchange activity and in other
circumstances where the funds' investment adviser believes doing so would be in
the best interests of the fund, each fund reserves the right to revise or
terminate the exchange privilege, limit the amount or number of exchanges, or
reject any exchange. You will be notified in the event this happens to the
extent required by law.
 
OPTIONAL FEATURES AND SERVICES
 
SYSTEMATIC INVESTMENT
 
Once you have opened an account, you may make regular investments of $50 or more
a month through automatic deductions from your bank account (see "Fund Direct --
Electronic Funds Transfer" below), or directly from your paycheck. To invest
regularly from your bank account, simply complete the appropriate section of the
account application. To invest regularly from your paycheck, call Nuveen for a
Payroll Direct Deposit Enrollment form. If you need additional copies of these
forms, or would like assistance completing them, contact your financial adviser
or call Nuveen at (800) 621-7227.
 
One of the benefits of systematic investing is "dollar cost averaging." Because
you are making fixed payments, you buy fewer shares when the price is high, and
more when the price is low. As a result, the average price you pay will be less
than the average share price of fund shares over this period. Dollar cost
averaging does not assure profits or protect against losses in a steadily
declining market. Since dollar cost averaging involves continuous investment
regardless of fluctuating price levels, you should consider your financial
ability to continue investing in declining as well as rising markets before
deciding to invest in this way.
 
Systematic investing may also make you eligible for reduced sales charges on
shares of the fund as well as other Nuveen mutual funds (see "Other Sales Charge
Discounts").
 
THE POWER OF SYSTEMATIC INVESTING
 
The chart below illustrates the benefits of systematic investing based on a
$3,000 initial investment and subsequent monthly investments of $100 over 20
years. The example assumes you earn a return of 4%, 5% or 6% annually on your
investment and that you reinvest all dividends. These annual returns do not
reflect past or projected fund performance.
 
THE POWER OF SYSTEMATIC INVESTING
 
[LOGO]
 
SYSTEMATIC WITHDRAWALS
 
If the value of your fund account is at least $10,000, you may request to have
$50 or more withdrawn automatically from your account. You may elect to receive
payments monthly, quarterly, semi-annually or annually and may choose to receive
a check, have the monies transferred directly into your bank account (see "Fund
Direct -- Electronic Funds Transfer" below), paid to a third party or sent
payable to you at an address other than your address of record. You must
complete the appropriate section of the account application or Account Update
Form to participate in the fund's systematic withdrawal plan.
 
You should not establish systematic withdrawals if you intend to make concurrent
purchases of Class A, B or C shares because you may unnecessarily pay a sales
charge or CDSC on these purchases.
 
REINSTATEMENT PRIVILEGE
 
If you redeem fund shares, you may reinvest all or part of your redemption
proceeds in shares of the same class up to one year later without incurring any
applicable sales charges, and your prior holding period will be reinstated for
the purpose of determining applicable sales charges. You may exercise this
privilege only once per redemption request.
 
If you paid a CDSC, your CDSC will be refunded and your holding period
reinstated. You should consult your tax adviser about the tax consequences of
exercising your reinstatement privilege.
 
FUND DIRECT-ELECTRONIC FUNDS TRANSFER
 
You may arrange to transfer funds electronically between your bank account and
your fund account by completing the appropriate section of the account
application or the Account Update Form. If you need additional copies of these
forms, or would like assistance completing them, contact your financial adviser
or call Nuveen at (800) 621-7227. You may use Fund
 
 25
<PAGE>   133
 
Direct to quickly and conveniently purchase or sell shares by telephone,
systematically invest or withdraw funds, or send dividend payments directly to
your bank account.
 
In addition, if you have established electronic funds transfer privileges on
your account, you may request that redemption proceeds of $1,000 or more be sent
by Federal Reserve wire directly into your bank account. While you will
generally receive your redemption proceeds more quickly than a regular telephone
redemption via Fund Direct, the fund may charge you a fee for this expedited
service.
 
DIVIDENDS AND TAXES
 
HOW THE FUNDS PAY DIVIDENDS
 
The funds pay tax-free dividends monthly and any taxable capital gains or other
distributions once a year in December. The funds declare dividends on or about
the ninth of each month and generally pay dividends on the first business day of
the following month.
 
PAYMENT AND REINVESTMENT OPTIONS
 
The funds automatically reinvest your dividends each month in additional fund
shares of the same share class unless you request otherwise. You may request to
have your dividends paid to you by check, deposited directly into your bank
account, paid to a third party, sent to an address other than your address of
record or reinvested in shares of the same share class of another Nuveen mutual
fund. If you wish to do so, complete the appropriate section of the account
application, contact your financial adviser or call Nuveen at (800) 621-7227.
 
CALCULATION OF FUND DIVIDENDS
 
Each fund pays dividends based upon its past and projected net income in order
to distribute substantially all of its net income each fiscal year.
 
In order to maintain a more stable monthly dividend, each fund may sometimes
distribute less or more than the amount of net income earned in a particular
period as a result of fluctuations in a fund's net income. Undistributed net
income is included in the fund's share price; similarly, distributions from
previously undistributed net income reduce the fund's share price. This dividend
policy is not expected to affect the management of a fund's portfolio.
 
Dividends for Class A, B, C and R shares are determined in the same manner and
at the same time. Dividends per share will vary based on which class of fund
shares you own, reflecting the different ongoing fees and other expenses of each
class.
 
TAXES AND TAX REPORTING
 
The discussion below and in the statement of additional information provides
general tax information related to an investment in fund shares. Because tax
laws are complex and often change, you should consult your tax adviser about the
tax consequences of a specific fund investment.
 
Each fund primarily invests in municipal bonds from a specific state or in
municipal bonds whose income is otherwise exempt from regular federal, state and
local income taxes. Consequently, the regular monthly dividends you receive will
be exempt from regular federal, state and, in some cases, local income taxes.
All or a portion of these dividends, however, may be subject to the federal
alternative minimum tax (AMT).
 
Although the funds do not seek to realize taxable income or capital gains, the
funds may realize and distribute taxable income or capital gains from time to
time as a result of each fund's normal investment activities. Each fund will
distribute in December any taxable income or capital gains realized over the
preceding year. Net short-term gains are taxable as ordinary income. Net
longterm capital gains are taxable as long-term capital gains regardless of how
long you have owned your investment. Taxable dividends do not qualify for a
dividends received deduction if you are a corporate shareholder.
 
Each year, you will receive a year-end statement that describes the tax status
of dividends paid to you during the preceding year, including the source of its
investment income by state and the portion of its income that is subject to AMT.
You will receive this statement from the firm where you purchased your fund
shares if you hold your investment in street name; Nuveen will send you this
statement if you hold your shares in registered form.
 
The tax status of your dividends is not affected by whether you reinvest your
dividends or receive them in cash.
 
BUYING OR SELLING SHARES CLOSE TO A RECORD DATE
 
If you purchase fund shares shortly before the record date for a taxable
dividend, the entire dividend you receive may be taxable to you even though a
portion of the dividend effectively represents a return of your purchase price.
This is commonly known as "buying a dividend." Similarly, if you sell or
exchange fund shares shortly before the record date for a tax-exempt
 
 26
<PAGE>   134
 
dividend, a portion of the price you receive may be treated as a taxable capital
gain even though it reflects tax-free income earned but not yet distributed by
the fund.
 
REDEEMING SHARES HELD LESS THAN SIX MONTHS
 
If you sell or exchange shares that you have owned for less than six months and
you recognized a short-term capital loss when you redeemed your shares, the loss
you can claim will be reduced by the amount of tax-free dividends paid to you on
those shares. Any remaining short-term capital loss will be treated as long-term
capital loss to the extent you also received capital gain dividends on those
shares. You should consult your tax adviser for complete information about these
rules. Please consider the tax consequences carefully when contemplating a
redemption.
 
OTHER IMPORTANT TAX INFORMATION
 
In order to avoid corporate taxation of its earnings and to pay tax-free
dividends, each fund must meet certain I.R.S. requirements that govern the
fund's sources of income, diversification of assets and distribution of earnings
to shareholders. Each fund has met these requirements in the past and intends to
do so in the future. If a fund failed to do so, the fund would be required to
pay corporate taxes on its earnings and all your distributions would be taxable
as ordinary income.
 
A fund may be required to withhold 31% of certain of your dividends if you have
not provided the fund with your correct taxpayer identification number (normally
your social security number), or if you are otherwise subject to back-up
withholding.
 
If you receive social security benefits, you should be aware that tax-free
income is taken into account in calculating the amount of these benefits that
may be subject to federal income tax.
 
If you borrow money to buy fund shares, you may not deduct the interest on that
loan. Under I.R.S. rules, fund shares may be treated as having been bought with
borrowed money even if the purchase cannot be traced directly to borrowed money.
 
If you are subject to the alternative minimum tax, a portion of your regular
monthly dividends may be taxable.
 
TAXABLE EQUIVALENT YIELDS
 
The taxable equivalent yield is the current yield you would need to earn on a
taxable investment in order to equal a stated tax-free yield on a municipal
investment. To assist you to more easily compare municipal investments like the
funds with taxable alternative investments, the table below presents the taxable
equivalent yields for a range of hypothetical tax-free yields and tax rates:

PORTFOLIO MANAGERS
 
Overall investment management strategy and operating policies for the funds are
set by the Investment Policy Committee of Nuveen Advisory. The Investment Policy
Committee is comprised of the principal executive officers and portfolio
managers of Nuveen Advisory and meets regularly to review economic conditions,
the outlook for the financial markets in general and the status of the municipal
markets in particular. Day-to-day operation of each fund and the execution of
its specific investment strategies is the responsibility of the designated
portfolio manager described below.
 
Michael Davern is the portfolio manager for the Alabama and Georgia Funds. Mr.
Davern has managed these funds since 1994, first as a Vice President of Flagship
Financial Inc., the funds' prior investment adviser, and then as a Vice
President of Nuveen Advisory after the acquisition of Flagship Resources Inc. by
The John Nuveen Company in January 1997. Walter Parker is the portfolio manager
for the North Carolina, South Carolina, and Tennessee Funds. Mr. Parker has
managed these funds since 1995, and since 1994 had been a Vice President of
Flagship Financial Inc., the funds' prior investment adviser, until becoming a
Vice President of Nuveen Advisory upon the acquisition of Flagship Resources
Inc. by The John Nuveen Company in January 1997. Jan Terbreuggen is the
portfolio manager for the Louisiana Fund. Mr. Terbrueggen has managed the fund
as a Vice President of Flagship Financial Inc., the funds' prior investment
adviser, since 1992, until becoming a Vice President of Nuveen Advisory upon the
acquisition of Flagship Resources Inc. by The John Nuveen Company in January
1997.
 
THE DISTRIBUTOR
 
John Nuveen and Co. Incorporated serves as the selling agent and distributor of
the funds' shares. In this capacity, Nuveen manages the offering of the funds'
shares and is responsible for all sales and promotional activities. In order to
reimburse Nuveen for its costs in connection with these activities, including
compensation paid to authorized dealers, each fund has adopted a distribution
and service plan under Rule 12b-1 of the Investment Company Act of 1940.
 
The plan authorizes each fund to pay Nuveen an annual 0.20% service fee on the
average daily net assets of each class of shares outstanding. The plan also
authorizes each fund to pay Nuveen an annual 0.75% distribution fee on the
average daily net assets of Class B shares outstanding. The plan also authorizes
each fund to pay Nuveen an annual 0.55% distribution fee on the average daily
net assets of Class C shares outstanding. In order to help compensate Nuveen for
the sales commission paid to financial advisers at the time of sale on sales of
Class B and Class C shares, Nuveen retains the first
 
 28
<PAGE>   136
 
year's service fee on sales of Class B shares and all Class B distribution fees,
and retains the first year's service and distribution fees on sales of Class C
shares. Otherwise, Nuveen pays these fees to the broker of the record. The
statement of additional information contains a detailed description of the plan
and its provisions.
 
TRANSFER AGENT
 
The funds have appointed Boston Financial, P.O. Box 8509, Boston, MA,
02266-8509, as the transfer agent responsible for distributing dividend payments
and providing certain bookkeeping, data processing and other administrative
services in connection with the maintenance of shareholder accounts.
 
HOW THE FUNDS REPORT PERFORMANCE
 
Each fund may quote its yield and total return in reports to shareholders, sales
literature and advertisements. The funds may also compare their investment
results to various passive indices or other mutual funds with similar investment
objectives. Comparative performance information may include data from Lipper
Analytical Services, Inc., Morningstar, Inc. and other industry publications.
See the statement of additional information for a more detailed discussion.
 
You may find more information about each fund's performance in its annual
report. Call Nuveen at (800) 621-7227 for a free copy.
 
HOW FUND SHARES ARE PRICED
 
The share price for each class of fund shares, also called its net asset value
(NAV), is calculated every business day as of the close of regular trading on
the New York Stock Exchange (normally 4 p.m. Eastern time). The net asset value
for a class of fund shares is computed by calculating the total value of the
class' portion of the fund's portfolio investments and other assets, subtracting
any liabilities or other debts, and dividing by the total number of its shares
outstanding.
 
The prices of municipal bonds in each fund's investment portfolio are provided
by a pricing service approved and supervised by the fund's Board of Trustees.
When price quotes are not readily available (which is usually the case for
municipal securities), the pricing service establishes fair market value based
on yields or prices of municipal bonds of comparable quality, type of issue,
coupon, maturity and rating, indications of value from securities dealers and
general market conditions.
 
ORGANIZATION
 
The Trust is an open-end investment company under the Investment Company Act of
1940, consisting of multiple funds. The shares of each fund are divided into
classes. Each class of shares represents an interest in the same portfolio of
investments and the shares of each class have equal rights as to voting,
redemption, dividends and liquidation. However, each class bears different sales
charges and service fees.
 
The funds are not required to and do not intend to hold annual meetings.
Shareholders owning ten percent or more of a fund's outstanding shares may call
a special meeting for any purpose, including to elect or remove trustees or to
change fundamental policies.

APPENDIX
 
SPECIAL STATE CONSIDERATIONS
 
Because the funds primarily purchase municipal bonds from a specific state, each
fund also bears investment risk from economic, political or regulatory changes
that could adversely affect municipal bond issuers in that state and therefore
the value of the fund's investment portfolio. The following discussion of
special state considerations was obtained from official offering statements of
these issuers and has not been independently verified by the funds. The
discussion includes general state tax information related to an investment in
fund shares. Because tax laws are complex and often change, you should consult
your tax adviser about the state tax consequences of a specific fund investment.
See the statement of additional information for further information.
 
ALABAMA
 
The industrialization of Alabama's economy over the past two decades has
resulted in a manufacturing sector that represents just over a quarter of the
state's gross product and 21.7% of employment. In recent years, the importance
of the service sector has grown as regional concentrations such as the medical
complex in Birmingham and the high technology research center at Huntsville
stimulate growth. The trade and service sectors have provided 75% of job growth
in recent years.
 
The state's unemployment rate was 4.5% in June 1997. Per capita income growth
significantly outpaced the national average during the period from 1980 to 1990.
However, personal income in the state remains below the national median at
$20,055, about 82% of the U.S. per capita average.
 
Moody's gives Alabama general obligation bonds an Aa rating while Standard &
Poor's gives them an AA rating.
 
TAX TREATMENT.
 
The Alabama Fund's regular monthly dividends will not be subject to Alabama
personal income taxes to the extent they are paid out of income earned on
Alabama municipal bonds or U.S. government securities. You will be subject to
Alabama personal income taxes, however, to the extent the Alabama Fund realizes
any taxable income or capital gains even if such income or gains are not
distributed to you as dividends, or if you sell or exchange Alabama Fund shares
and realize a capital gain on the transaction.
 
The treatment of corporate shareholders of the Alabama Fund is similar to that
described above.
 
GEORGIA
 
One of the nation's fastest growing states in terms of population, Georgia has
benefited from steady economic and employment growth as a result of the State's
stable and broad-based trade and service economy, low average cost of living,
and extensive transportation infrastructure. This economic growth as well as the
State's healthy financial position were recognized in the State's recent rating
upgrade from AA+ to AAA by Standard & Poor's.
 
The State's unemployment level is low at 4.4% in June, 1997, down from 5.1% in
June of 1996. Per capita income is $22,709, which is about 94% of the national
average and 104% of the region.
 
Georgia's tight financial policies and conservative management have resulted in
a substantial operating surplus of $476 million and an unreserved general fund
balance of $621 million in fiscal 1996. The large surplus enabled the State to
increase reserves for debt service and expand the fiscal 1997 budget. As of July
31, 1997, Georgia's general obligation debt carries triple-A ratings from
Standard & Poor's, Moody's, and Fitch.
 
TAX TREATMENT.
 
The Georgia Fund's regular monthly dividends will not be subject to Georgia
personal income taxes to the extent they are paid out of income earned on
Georgia municipal bonds or U.S. government securities. You will be subject to
Georgia personal income taxes, however, to the extent the Georgia Fund
distributes any taxable income or realized capital gains, or if you sell or
exchange Georgia Fund shares and realize a capital gain on the transaction.
 
The treatment of corporate shareholders of the Georgia Fund is similar to that
described above.
 
LOUISIANA
 
Louisiana's economic base has experienced some improvement after the recession
of the 1980's. Per capita personal income has improved and was $19,824 in 1996,
but remains flat at about 80% of the national average. The annual average
unemployment rate for the State in 1996 was 6.7%, well above the national
average of 5.4%. Employment projections show increases of approximately 2%
annually, with 66,000 additional jobs expected in the next two years.
 
 30
<PAGE>   138
 
The State possesses natural resources which have played a significant role in
driving the economy. Chemicals provide the largest employment in the
manufacturing industry. Tourism is the second largest industry in the state,
adding $6.6 billion to the economy and generating $450 million in state and
local taxes by the end of 1995. Louisiana will continue to rely on the gaming
industry, despite a sector employment drop of about 4% in 1996 due to the
consolidation and downsizing of hotels and casinos.
 
Financial operations have stabilized somewhat in recent years. The General Fund
ending balance increased 36% from fiscal year 1995 to fiscal year 1996. Debt
service comprises approximately 4% of State expenditures. Debt levels have
moderated, declining approximately 42% since extremely high levels in 1987. This
decline is partly due to the recent retirement and defeasement of bonds once
issued by the Louisiana Recovery District to recover deficits experienced in the
1980's.
 
The State of Louisiana general obligation bond ratings by Standard & Poor's and
Fitch are A- and A, respectively. Moody's revised Louisiana's general obligation
rating from Baa1 to A3 in March of 1997.
 
TAX TREATMENT.
 
The Louisiana Fund's regular monthly dividends will not be subject to Louisiana
personal income tax to the extent they are paid out of income earned on
Louisiana municipal obligations or U.S. government securities. You will be
subject to Louisiana personal income tax, however, to the extent the Louisiana
Fund distributes any taxable income or realized capital gains, or if you sell or
exchange Louisiana Fund shares and realize capital gain on the transaction.
 
The treatment of corporate shareholders of the Louisiana Fund is similar to that
described above.
 
NORTH CAROLINA
 
North Carolina's economy continues to grow and diversify. The State ranks among
the top ten states in economic growth, as measured by employment, population,
and personal income growth. While manufacturing remains the State's major
employment sector, the services and retail trade sectors also supply a
significant percentage of employment. Growth in the high-technology sector has
helped diversify the State's economy and also has helped offset recent
employment losses in the textile, apparel, and tobacco industries.
 
The State's unemployment rate was 3.6% in June 1997, below the national average
of 5.0% in June 1997 and down from the State's 4.3% rate in June 1996. Per
capita income grew to $22,010 in 1996 but remains below the national average of
$24,731.
 
The State has implemented sound financial policies and maintains low debt
levels. Its Constitution mandates that total expenditures not exceed receipts
for the same period plus any surplus available at the start of the fiscal year.
These conservative policies, combined with the State's economic recovery,
resulted in budget surpluses in each fiscal year 1992-1996. In February 1997,
Moody's, Standard & Poor's, and Fitch confirmed their respective triple-A
ratings for the State.
 
TAX TREATMENT.
 
The North Carolina Fund's regular monthly dividends will not be subject to North
Carolina personal income taxes to the extent they are paid out of income earned
on North Carolina municipal bonds or obligations of the U.S. government. You
will be subject to North Carolina personal income taxes, however, to the extent
the North Carolina fund distributes any taxable income or realized capital
gains, or if you sell or exchange North Carolina Fund shares and realize a
capital gain on the transaction.
 
The treatment of corporate shareholders of the North Carolina Fund is similar to
that described above.
 
SOUTH CAROLINA
 
Though still reliant on the textile industry, South Carolina's economy has
diversified into other areas such as trade, services, and durable goods
manufacturing. While not a wealthy state, employment growth has outpaced the
national growth rate. Steady economic gains are expected to continue. The
strength of the job market, combined with low housing costs and the State's
attractive climate, are expected to continue to attract new residents.
 
The State's June 1997 unemployment rate of 5.1% stands slightly above the 5.0%
national level. Per capita income was $19,755 in 1996, equal to about 81% of the
national average with personal income growth exceeding the national growth rate.
 
South Carolina's Constitution mandates a balanced budget and employs several
means to ensure its achievement. The Constitution also requires the government
to set aside 3% of general fund revenues in a General Reserve Fund and 2% in a
Capital Reserve Fund as a hedge against any year end deficit. This sound fiscal
policy allowed South Carolina to end fiscal 1996 with a general fund balance of
$285 million, $26 million over fiscal 1995. As of July 31, 1997, South
Carolina's general obligation debt carries triple-A ratings from Standard &
Poor's, Moody's and Fitch.
 
 31
<PAGE>   139
 
TAX TREATMENT.
 
The South Carolina Fund's regular monthly dividends will not be subject to South
Carolina personal income taxes to the extent they are paid out of income earned
on South Carolina municipal bonds or U.S. government securities. You will be
subject to South Carolina personal income taxes, however, to the extent the
South Carolina Fund distributes any taxable income or realized capital gains, or
if you sell or exchange South Carolina Fund shares and realize a capital gain on
the transaction.
 
The treatment of corporate shareholders of the South Carolina Fund is similar to
that described above.
 
TENNESSEE
 
Tennessee's economy has diversified over the past several years. Traditionally a
manufacturing state, Tennessee has shifted toward services and trade industries.
Tennessee's average annual unemployment rate in 1996 was 5.2%, compared to the
national average rate of 5.4%. The state's population has grown steadily by
approximately 1% annually. Personal income grew over 87% from 1983 to 1993 to
reach $18,434 per capita. The per capita average increased again to $21,764 in
1996.
 
Tennessee's Constitution requires that a fiscal year's expenditures not exceed
that year's revenues and available reserves. Taxes represent the largest source
of governmental revenues, comprising 50.3% of revenues in 1996. At 1996 fiscal
year end, general obligation debt in Tennessee totaled $634.7 million.
Tennessee's solid fiscal budget management is reflected in its general
obligation ratings of Aaa/AA+/AAA by Moody's, Standard & Poor's and Fitch,
respectively.
 
TAX TREATMENT.
 
The Tennessee Fund's regular monthly dividends will not be subject to Tennessee
personal income taxes to the extent they are paid out of income earned on or
capital gains realized from the sale of Tennessee municipal bonds or U.S.
government securities. You will be subject to Tennessee personal income taxes,
however, to the extent the Tennessee Fund distributes any taxable income or
realized capital gains on other securities. You will not be subject to Tennessee
personal income taxes if you sell or exchange Tennessee Fund shares.
 
The treatment of corporate shareholders of the Tennessee fund differs from that
described above.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
     This Agreement and Plan of Reorganization (the "Agreement") is made as of
            , 1998, by and between the             (the "Acquiring Fund") series
of the                   Trust, a Massachusetts business trust formed under the
laws of the State of Massachusetts (the "Acquiring Fund Trust"), and the
                  (the "Acquired Fund") series of the                   Trust
(the "Acquired Fund Trust").
 
                                  WITNESSETH:
 
     WHEREAS, the Board of Trustees of the Acquiring Fund Trust and the Acquired
Fund Trust, on behalf of the Acquiring Fund and Acquired Fund respectively, have
determined that entering into this Agreement for the Acquiring Fund to acquire
the assets and liabilities of the Acquired Fund is in the best interests of the
shareholders of each respective fund; and
 
     WHEREAS, the parties intend that this transaction qualify as a
reorganization within the meaning of Section 368(a)(1) of the Internal Revenue
Code of 1986, as amended (the "Code");
 
     NOW, THEREFORE, in consideration of the mutual promises contained herein,
and intending to be legally bound hereby, the parties hereto agree as follows:
 
1. PLAN OF TRANSACTION.
 
     A. Transfer of Assets. Upon satisfaction of the conditions precedent set
forth in Sections 7 and 8 hereof, the Acquired Fund will convey, transfer and
deliver to the Acquiring Fund at the closing, provided for in Section 2 hereof,

the Closing Date) as more fully set forth on Schedule 1 hereto, and as amended
from time to time prior to the Closing Date (as defined below), free and clear
of all liens, encumbrances and claims whatsoever (the assets so transferred
collectively being referred to as the "Assets").
 
     B. Consideration. In consideration thereof, the Acquiring Fund agrees that
on the Closing Date, defined in Section 2 hereof, the Acquiring Fund will (i)
deliver to the Acquired Fund, full and fractional Class A, Class B, Class C and

Fund's Liabilities. The calculation of full and fractional Class A, Class B,
Class C and Class R shares of beneficial interest of the Acquiring Fund to be
exchanged shall be carried out to no less than two (2) decimal places. On the

complete and updated list of such holders (including addresses and taxpayer
identification numbers), and the Acquiring Fund agrees promptly to comply with

the validity, propriety or correctness of such instruction, but shall assume

     G. Opinion of Counsel. The Acquired Fund shall have received the opinion of
Vedder, Price, Kaufman & Kammholz, counsel for the Acquiring Fund Trust and
Acquiring Fund, dated as of the Closing Date, addressed to the Acquired Fund
substantially in the form and to the effect that: (i) the Acquiring Fund Trust
is duly formed and in good standing as a business trust under the laws of the
State of Massachusetts; (ii) the Board of Trustees of the Acquiring Fund Trust
has duly designated the Acquiring Fund as a series of the Acquiring Fund Trust
pursuant to the terms of the Declaration of Trust of the Acquiring Fund Trust;
(iii) the Acquiring Fund Trust is registered as an open-end management company
under the 1940 Act; (iv) this Agreement and the reorganization provided for
herein and the execution of this Agreement have been duly authorized and
approved by all requisite action of the Acquiring Fund Trust and this Agreement
has been duly executed and delivered by the Acquiring Fund Trust on behalf of
the Acquiring Fund and (assuming the Agreement is a valid and binding obligation
of the other parties thereto) is a valid and binding obligation of the Acquiring
Fund; except as such enforceability may be limited by bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium or similar law affecting
creditors' rights generally, or by general principals of equity (regardless of
whether enforcement is sought in a proceeding at equity at law); (v) neither the
execution or delivery by the Acquiring Fund Trust on behalf of the Acquiring
Fund of this Agreement nor the consummation by the Acquiring Fund Trust or
Acquiring Fund of the transactions contemplated thereby contravene the Acquiring
Fund Trust's Declaration of Trust, or, to the best of their knowledge, violate
any provision of any statute or any published regulation or any judgment or
order disclosed to it by the Acquiring Fund Trust as being applicable to the
Acquiring Fund Trust or the Acquiring Fund; (vi) to the best of their knowledge
based solely on the certificate of an appropriate officer of the Acquiring Fund
attached hereto, there is no pending or threatened litigation which would have
the effect of prohibiting any material business practice or the acquisition of
any material property or the conduct of any material business of the Acquiring
Fund or might have a material adverse effect on the value of any assets of the
Acquiring Fund; (vii) the Acquiring Fund's Shares have been duly authorized and
upon issuance thereof in accordance with this Agreement will, subject to certain
matters regarding the liability of a shareholder of a Massachusetts business
trust, be validly issued, fully paid and nonassessable; (viii) except as to
financial statements and schedules and other financial and statistical data
included or incorporated by reference therein and subject to usual and customary
qualifications with respect to Rule 10b-5 type opinions, as of the effective
date of the Registration Statement filed pursuant to the Agreement, the portions
thereof pertaining to the Acquiring Fund comply as to form in all material
respects with the requirements of the Securities Act, the Securities Exchange
Act and the 1940 Act and the rules and regulations of the SEC thereunder and no
facts have come to counsel's attention which would cause them to believe that as
of the effectiveness of the portions of the Registration Statement applicable to
the Acquiring Fund, the Registration Statement contained any untrue statement of
a material fact or omitted to state any material fact required to be stated
therein or necessary to make the statements therein not misleading, and (ix) to
the best of their knowledge and information and subject to the qualifications
set forth below, the execution and delivery by the Acquiring Fund Trust on
behalf of the Acquiring Fund of the Agreement and the consummation of the
transactions therein contemplated do not require, under the laws of the States
of Massachusetts and Illinois or the federal laws of the United States, the
consent, approval,
 
                                       A-8
<PAGE>   150
 
authorization, registration, qualification or order of, or filing with, any
court or governmental agency or body (except such as have been obtained).
Counsel need express no opinion, however, as to any such consent, approval,
authorization, registration, qualification, order or filing (a) which may be
required as a result of the involvement of other parties to the Agreement in the
transactions contemplated by the Agreement because of their legal or regulatory
status or because of any other facts specifically pertaining to them; (b) the
absence of which does not deprive the Acquired Fund of any material benefit
under the Agreement; or (c) which can be readily obtained without significant
delay or expense to the Acquired Fund, without loss to the Acquired Fund of any
material benefit under the Agreement and without any material adverse effect on
the Acquired Fund during the period such consent, approval, authorization,
registration, qualification or order was obtained. The foregoing opinion relates
only to consents, approvals, authorizations, registrations, qualifications,
orders or filings under (a) laws which are specifically referred to in this
opinion, (b) laws of the States of Massachusetts and Illinois and the federal
laws of the United States which, in counsel's experience, are normally
applicable to transactions of the type provided for in the Agreement and (c)
court orders and judgments disclosed to counsel by the Acquiring Fund Trust on
behalf of the Acquiring Fund in connection with the opinion. In addition,
although counsel need not specifically have considered the possible
applicability to the Acquiring Fund Trust or the Acquiring Fund of any other
laws, orders or judgments, nothing has come to their attention in connection
with their representation of the Acquiring Fund Trust and the Acquiring Fund in
this transaction that has caused them to conclude that any other consent,
approval, authorization, registration, qualification, order or filing is
required. In giving the opinions set forth above, counsel may state that it is
relying on certificates of officers of the Acquiring Fund with regard to matters
of fact and certain certificates and written statements of government officers
with respect to the good standing of the Acquiring Fund and on the opinion of
Bingham Dana LLP as to matters of Massachusetts law.
 
     H. Officer Certificates. The Acquired Fund shall have received a
certificate of an authorized officer of the Acquiring Fund, dated as of the
Closing Date, certifying that (i) the representations and warranties set forth
in Section 5 are true and correct on the Closing Date, together with certified
copies of the resolutions adopted by the Board of Trustees shall be furnished to
the Acquired Fund and that (ii) from the date hereof through the Closing Date,
there shall not have been any change in the business, results of operations,
assets or financial condition or the manner of conducting the business of the
Acquiring Fund, other than changes in the ordinary course of its business, which
has had a material adverse effect on such business, results of operations,
assets or financial condition.
 
8. CONDITIONS TO OBLIGATIONS OF ACQUIRING FUND.
 
     The obligations of the Acquiring Fund hereunder with respect to the
consummation of the Reorganization are subject to the satisfaction, or written
waiver by the Acquiring Fund of the following conditions:

and warranties of the Acquired Fund contained herein shall be true in all

Acquiring Fund shall have received a certificate of an authorized officer of the
Acquired Fund satisfactory in form and substance to the Acquiring Fund so
stating. The Acquired Fund shall have performed and complied in all material
respects with all agreements, obligations and covenants required by this
Agreement to be so performed or complied with by them on or prior to the Closing

agency or entity seeking any of the foregoing be pending. There shall not be any
action taken, or any statute, rule, regulation or order enacted, entered,
enforced or deemed applicable to the transactions contemplated by this
Agreement, which makes the consummation of the transactions contemplated by this
Agreement illegal.
 
     F. Tax Opinion. The Acquiring Fund shall have obtained an opinion from
Vedder, Price, Kaufman & Kammholz, counsel for the Acquired Fund, dated as of
the Closing Date, addressed to the Acquiring Fund Trust, Acquired Fund Trust,

<PAGE>   151
 
this Agreement comply with the requirements of a reorganization as described in
Section 368(a) of the Code substantially in the form attached as Annex A.
 
     G. Opinion of Counsel. The Acquiring Fund shall have received the opinion
of Vedder, Price, Kaufman & Kammholz, counsel for the Acquired Fund Trust and
the Acquired Fund, dated as of the Closing Date, addressed to the Acquiring
Fund, substantially in the form and to the effect that: (i) the Acquired Fund
Trust is duly formed and existing as a trust under the laws of the State of
Massachusetts; (ii) the Board of Trustees of the Acquired Fund Trust has duly
designated the Acquired Fund as a series of the Acquired Fund Trust pursuant to
the terms of the Declaration of Trust of the Acquired Fund Trust; (iii) the
Acquired Fund Trust is registered as an open-end management company under the
1940 Act; (iv) this Agreement and the reorganization provided for herein and the
execution of this Agreement have been duly authorized by all requisite action of
the Acquired Fund Trust and this Agreement has been duly executed and delivered
by the Acquired Fund Trust on behalf of the Acquired Fund and (assuming the
Agreement is a valid and binding obligation of the other parties thereto) is a
valid and binding obligation of the Acquired Fund, except as such enforceability
may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization,
moratorium or similar law affecting creditors' rights generally, or by general
principals of equity (regardless of whether enforcement is sought in a
proceeding at equity or law); (v) neither the execution or delivery by the
Acquired Fund Trust on behalf of the Acquired Fund of this Agreement nor the
consummation by the Acquired Fund Trust or Acquired Fund of the transactions
contemplated thereby contravene the Acquired Fund Trust's Declaration of Trust
or, to their knowledge, violate any provision of any statute, or any published
regulation or any judgment or order disclosed to them by the Acquired Fund Trust
as being applicable to the Acquired Fund Trust or Acquired Fund; (vi) to their
knowledge based solely on the certificate of an appropriate officer of the
Acquired Fund attached thereto, there is no pending, or threatened litigation
involving the Acquired Fund except as disclosed therein; (vii) except as to
financial statements and schedules and other financial and statistical data
included or incorporated by reference therein and subject to usual and customary
qualifications with respect to Rule 10b-5 type opinions, as of the effective
date of the Registration Statement filed pursuant to the Agreement, the portions
thereof pertaining to the Acquired Fund comply as to form in all material
respects with their requirements of the Securities Act, the Securities Exchange
Act and the 1940 Act and the rules and regulations of the SEC thereunder and no
facts have come to counsel's attention which cause them to believe that as of
the effectiveness of the portions of the Registration Statement applicable to
the Acquired Fund, the Registration Statement contained any untrue statement of
a material fact or omitted to state any material fact required to be stated
therein or necessary to make the statements therein not misleading; and (viii)
to their knowledge and subject to the qualifications set forth below, the
execution and delivery by the Acquired Fund Trust on behalf of the Acquired Fund
of the Agreement and the consummation of the transactions therein contemplated
do not require, under the laws of the States of Massachusetts or Illinois, or
the federal laws of the United States, the consent, approval, authorization,
registration, qualification or order of, or filing with, any court or
governmental agency or body (except such as have been obtained under the
Securities Act, the 1940 Act or the rules and regulations thereunder.) Counsel
need express no opinion, however, as to any such consent, approval,
authorization, registration, qualification, order or filing (a) which may be
required as a result of the involvement of other parties to the Agreement in the
transactions contemplated by the Agreement because of their legal or regulatory
status or because of any other facts specifically pertaining to them; (b) the
absence of which does not deprive the Acquiring Fund of any material benefit
under such agreements; or (c) which can be readily obtained without significant
delay or expense to the Acquiring Fund, without loss to the Acquiring Fund of
any material benefit under the Agreement and without any material adverse effect
on them during the period such consent, approval authorization, registration,
qualification or order was obtained. The foregoing opinion relates only to
consents, approvals, authorizations, registrations, qualifications, orders or
filings under (a) laws which are specifically referred to in the opinion, (b)
laws of the States of Massachusetts or Illinois and the federal laws of the
United States which, in our experience, are normally applicable to transactions
of the type provided for in the Agreement and (c) court orders and judgments
disclosed to counsel by the Acquired Fund in connection with the opinion. In
addition, although counsel need not specifically considered the possible
applicability to the Acquired Fund of any other laws, orders or judgments,
nothing has come to their attention in connection with their representation of
the Acquired Fund in this transaction that has caused them to conclude that any
other consent, approval, authorization, registration, qualification, order or
filing is required. In giving the opinion set forth above, counsel may state
that it is relying on certificates of officers of the Acquired Fund with regard
to matters of fact and certain certificates and written statutes of government
officers with respect to the good standing of the Acquired Fund and on the
opinion of Bingham Dana LLP as to matters of Massachusetts law.
 
     H. Shareholder List. The Acquired Fund shall have delivered to the
Acquiring Fund an updated list of all shareholders of the Acquired Fund, as
reported by the Acquired Fund's transfer agent, as of [one (1)] business day

Closing Date, certifying that (i) the representations and warranties set forth
in Section 4 are true and correct on the Closing Date, together with certified
copies of the resolutions adopted by the Board of Trustees and shareholders and
that (ii) from the date of this Agreement through the Closing Date, there shall
not have been:
 
          (1) any change in the business, results of operations, assets, or
     financial condition or the manner of conducting the business of the
     Acquired Fund, other than changes in the ordinary course of its business,
     or any pending or threatened litigation, which has had or may have a
     material adverse effect on such business, results of operations, assets or
     financial condition;
 
          (2) issued any option to purchase or other right to acquire shares of

     terms in the Prospectus for the Acquired Fund;
 
          (3) any entering into, amendment or termination of any contract or
     agreement by Acquired Fund, except as otherwise contemplated by this
     Agreement;

without obtaining Acquired Fund's shareholder approval thereof.
 
     B. At any time prior to the Closing Date, either of the parties may by
written instrument signed by it (i) waive any inaccuracies in the
representations and warranties made to it contained herein and (ii) waive
compliance with any of the covenants or conditions made for its benefit
contained herein. No delay on the part of either party in exercising any right,
power or privilege hereunder shall operate as a waiver thereof, nor shall any
waiver on the part of any party of any such right, power or privilege, or any
single or partial exercise of any such right, power or privilege, preclude any
further exercise thereof or the exercise of any other such right, power or
privilege.

herein may be abandoned at any time prior to the Closing Date:

          (4) by either the Acquired Fund or Acquiring Fund, if the Closing has
     not occurred on or prior to [December 31, 1998] (provided that the rights
     to terminate this Agreement pursuant to this subsection (C)(iv) shall not
     be available to any party whose failure to fulfill any of its obligations
     under this Agreement has been the cause of or resulted in the failure of
     the Closing to occur on or before such date);

                  INVESTMENT POLICIES AND INVESTMENT PORTFOLIO
 
INVESTMENT POLICIES
 
     The investment objective and certain fundamental investment policies of
each Fund are described in the Prospectus. Each of the Funds, as a fundamental
policy, may not, without the approval of the holders of a majority of the shares
of that Fund:
 
          (1) Invest in securities other than Municipal Obligations and
     short-term securities, as described in the Prospectus. Municipal
     Obligations are municipal bonds that pay interest that is exempt from
     regular federal income taxes.
 
          (2) Invest more than 5% of its total assets in securities of any one
     issuer, except this limitation shall not apply to securities of the United
     States Government or to the investment of 25% of such Fund's assets.
 
          (3) Borrow money, except from banks for temporary or emergency
     purposes and not for investment purposes and then only in an amount not
     exceeding (a) 10% of the value of its total assets at the time of borrowing
     or (b) one-third of the value of the Fund's total assets including the
     amount borrowed, in order to meet redemption requests which might otherwise
     require the untimely disposition of securities. While any such borrowings
     exceed 5% of such Fund's total assets, no additional purchases of
     investment securities will be made by such Fund. If due to market
     fluctuations or other reasons, the value of the Fund's assets falls below
     300% of its borrowings, the Fund will 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.
 
          (4) Pledge, mortgage or hypothecate its assets, except that, to secure
     borrowings permitted by subparagraph (2) above, it may pledge securities
     having a market value at the time of pledge not exceeding 10% of the value
     of the Fund's total assets.
 
          (5) Issue senior securities as defined in the Investment Company Act
     of 1940, except to the extent such issuance might be involved with respect
     to borrowings described under item (3) above or with respect to
     transactions involving futures contracts or the writing of options within
     the limits described in the Prospectus and this Statement of Additional
     Information.
 
          (6) Underwrite any issue of securities, except to the extent that the
     purchase or sale of Municipal Obligations in accordance with its investment
     objective, policies and limitations, may be deemed to be an underwriting.
 
          (7) Purchase or sell real estate, but this shall not prevent any Fund
     from investing in Municipal Obligations secured by real estate or interests
     therein or foreclosing upon and selling such security.
 
          (8) Purchase or sell commodities or commodities contracts or oil, gas
     or other mineral exploration or development programs, except for
     transactions involving futures contracts within the limits described in the
     Prospectus and this Statement of Additional Information.
 
          (9) Make loans, other than by entering into repurchase agreements and
     through the purchase of Municipal Obligations or temporary investments in
     accordance with its investment objective, policies and limitations.
 
          (10) Make short sales of securities or purchase any securities on
     margin, except for such short-term credits as are necessary for the
     clearance of transactions.
 
          (11) Write or purchase put or call options, except to the extent that
     the purchase of a stand-by commitment may be considered the purchase of a
     put, and except for transactions involving options within the limits
     described in the Prospectus and this Statement of Additional Information.
 
          (12) Invest more than 25% of its total assets in securities of issuers
     in any one industry; provided, however, that such limitations shall not be
     applicable to Municipal Obligations issued by governments or political
     subdivisions of governments, and obligations issued or guaranteed by the
     U.S. Government, its agencies or instrumentalities.
 
          (13) Purchase or retain the securities of any issuer other than the
     securities of the Fund if, to the Fund's knowledge, those trustees of the
     Trust, or those officers and directors of Nuveen Advisory Corp. ("Nuveen
     Advisory"), who individually own beneficially more than 1/2 of 1% of the
     outstanding securities of such issuer, together own beneficially more than
     5% of such outstanding securities.
 
                                       B-2
<PAGE>   157
 
     In addition, each Fund, as a non-fundamental policy, may not invest more
than 15% of its net assets in "illiquid" securities, including repurchase
agreements maturing in more than seven days.
 
     For the purpose of applying the limitations set forth in paragraph (2)
above, an issuer shall be deemed the sole issuer of a security when its assets
and revenues are separate from other governmental entities and its securities
are backed only by its assets and revenues. Similarly, in the case of a
non-governmental user, such as an industrial corporation or a privately owned or
operated hospital, if the security is backed only by the assets and revenues of
the non-governmental user, then such non-governmental user would be deemed to be
the sole issuer. Where a security is also backed by the enforceable obligation
of a superior or unrelated governmental entity or other entity (other than a
bond insurer), it shall also be included in the computation of securities owned
that are issued by such governmental or other entity.
 
     Where a security is guaranteed by a governmental entity or some other
facility, such as a bank guarantee or letter of credit, such a guarantee or
letter of credit would be considered a separate security and would be treated as
an issue of such government, other entity or bank. Where a security is insured
by bond insurance, it shall not be considered a security issued or guaranteed by
the insurer; instead the issuer of such security will be determined in
accordance with the principles set forth above. The foregoing restrictions do
not limit the percentage of the Fund's assets that may be invested in securities
insured by any single insurer.
 
     The foregoing restrictions and limitations, as well as a Fund's policies as
to ratings of portfolio investments, will apply only at the time of purchase of
securities, and the percentage limitations will not be considered violated
unless an excess or deficiency occurs or exists immediately after and as a
result of an acquisition of securities, unless otherwise indicated.
 
     The foregoing fundamental investment policies, together with the investment
objective of each Fund, cannot be changed without approval by holders of a
"majority of the Fund's outstanding voting shares." As defined in the Investment
Company Act of 1940, this means the vote of (i) 67% or more of the Fund's shares
present at a meeting, if the holders of more than 50% of the Fund's shares are
present or represented by proxy, or (ii) more than 50% of the Fund's shares,
whichever is less.
 
     The Nuveen Flagship Municipal Trust (the "Trust") is an open-end
diversified management series investment company organized as a Massachusetts
business trust on July 1, 1996. Each of the Funds is an open-end management
investment company organized as a series of the Nuveen Flagship Municipal Trust.
The Trust is an open-end management series company under SEC Rule 18f-2. Each
Fund is a separate series issuing its own shares. The Trust currently has five
series: the Nuveen Municipal Bond Fund (originally incorporated in Maryland on
October 8, 1976 and reorganized as a Massachusetts business trust on June 12,
1995); the Nuveen Insured Municipal Bond Fund (formerly a series of the Nuveen
Insured Tax-Free Bond Fund, Inc., a Minnesota corporation incorporated on July
14, 1986); the Nuveen Flagship All-American Municipal Bond Fund (formerly the
Flagship All-American Tax Exempt Fund, a series of the Flagship Tax Exempt Funds
Trust); the Nuveen Flagship Intermediate Municipal Bond Fund (formerly the
Flagship Intermediate Tax Exempt Fund, a series of the Flagship Tax Exempt Funds
Trust); and the Nuveen Flagship Limited Term Municipal Bond Fund (formerly the
Flagship Limited Term Tax Exempt Fund, a series of the Flagship Tax Exempt Funds
Trust). Certain matters under the Investment Company Act of 1940 which must be
submitted to a vote of the holders of the outstanding voting securities of a
series company shall not be deemed to have been effectively acted upon unless
approved by the holders of a majority of the outstanding voting securities of
each Fund affected by such matter.
 
     The Trust is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders of a trust may, under
certain circumstances, be held personally liable as partners for its
obligations. However, the Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Trust and requires that
notice of this disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Trust or the Trustees. The Declaration of Trust
further provides for indemnification out of the assets and property of the Trust
for all loss and expense of any shareholder personally liable for the
obligations of the Trust. Thus, the risk of a shareholder incurring financial
loss on account of shareholder liability is limited to circumstances in which
both inadequate insurance existed and the Trust itself were unable to meet its
obligations. The Trust believes the likelihood of these circumstances is remote.
 
PORTFOLIO SECURITIES
 
     As described in the Prospectus, each Fund invests primarily in a
diversified portfolio of Municipal Obligations issued within the 50 states and
certain U.S. possessions and territories. In general, Municipal Obligations
include debt obligations issued by states, cities and local authorities to
obtain funds for various public purposes, including
 
                                       B-3
<PAGE>   158
 
construction of a wide range of public facilities such as airports, bridges,
highways, hospitals, housing, mass transportation, schools, streets and water
and sewer works. Industrial development bonds and pollution control bonds that
are issued by or on behalf of public authorities to finance various
privately-rated facilities are included within the term Municipal Obligations if
the interest paid thereon is exempt from federal income tax.
 
     The investment assets of each Fund will consist of (1) Municipal
Obligations which are rated at the time of purchase within the four highest
grades (Baa or BBB or better) by Moody's Investors Service, Inc. ("Moody's"), by
Standard and Poor's Corporation ("S&P") or by Fitch Investors Service, Inc.
("Fitch"), (2) unrated Municipal Obligations which, in the opinion of Nuveen
Advisory, have credit characteristics equivalent to bonds rated within the four
highest grades by Moody's, S&P or Fitch, except that the Fund may not invest
more than 20% of its net assets in unrated bonds and (3) temporary investments
as described below, the income from which may be subject to state income tax or
to both federal and state income taxes. See Appendix A for more information
about ratings by Moody's, S&P, and Fitch.
 
     As described in the Prospectus, each Fund may invest in Municipal
Obligations that constitute participations in a lease obligation or installment
purchase contract obligation (hereafter collectively called "lease obligations")
of a municipal authority or entity. Although lease obligations do not constitute
general obligations of the municipality for which the municipality's taxing
power is pledged, a lease obligation is ordinarily backed by the municipality's
covenant to budget for, appropriate and make the payments due under the lease
obligation. However, certain lease obligations contain "non-appropriation"
clauses which provide that the municipality has no obligation to make lease or
installment purchase payments in future years unless money is appropriated for
such purpose on a yearly basis. Although nonappropriation lease obligations are
secured by the leased property, disposition of the property in the event of
foreclosure might prove difficult. A Fund will seek to minimize the special
risks associated with such securities by only investing in those
nonappropriation leases where Nuveen Advisory has determined that the issuer has
a strong incentive to continue making appropriations and timely payment until
the security's maturity. Some lease obligations may be illiquid under certain
circumstances. Lease obligations normally provide a premium interest rate which
along with regular amortization of the principal may make them attractive for a
portion of the assets of the Funds.
 
     Obligations of issuers of Municipal Obligations are subject to the
provisions of bankruptcy, insolvency and other laws affecting the rights and
remedies of creditors. In addition, the obligations of such issuers may become
subject to the laws enacted in the future by Congress, state legislatures or
referenda extending the time for payment of principal and/or interest, or
imposing other constraints upon enforcement of such obligations or upon
municipalities to levy taxes. There is also the possibility that, as a result of
legislation or other conditions, the power or ability of any issuer to pay, when
due, the principal of and interest on its Municipal Obligations may be
materially affected.
 
INSURANCE
 
     Each insured Municipal Obligation held by the Nuveen Insured Municipal Bond
Fund will either be (1) covered by an insurance policy applicable to a specific
security and obtained by the issuer of the security or a third party at the time
of original issuance ("Original Issue Insurance"), (2) covered by an insurance
policy applicable to a specific security and obtained by the Fund or a third
party subsequent to the time of original issuance ("Secondary Market
Insurance"), or (3) covered by a master municipal insurance policy purchased by
the Fund ("Portfolio Insurance"). The Fund currently maintains a policy of
Portfolio Insurance with MBIA Insurance Corporation, AMBAC Indemnity
Corporation, Financial Security Assurance, Inc., and Financial Guaranty
Insurance Company, and may in the future obtain other policies of Portfolio
Insurance, depending on the availability of such policies on terms favorable to
the Fund. However, the Fund may determine not to obtain such policies and to
emphasize investments in Municipal Obligations insured under Original Issue
Insurance or Secondary Market Insurance. In any event, the Fund will only obtain
policies of Portfolio Insurance issued by insurers whose claims-paying ability
is rated Aaa by Moody's Investors Service, Inc. ("Moody's") or AAA by Standard &
Poor's Corporation ("S&P"). The Fund currently intends to obtain insurance
polices only from mono-line insurers specializing in insuring municipal debt.
Municipal Obligations covered by Original Issue Insurance or Secondary Market
Insurance are themselves typically assigned a rating of Aaa or AAA, as the case
may be, by virtue of the Aaa or AAA claims-paying ability of the insurer and
would generally be assigned a lower rating if the ratings were based primarily
upon the credit characteristics of the issuer without regard to the insurance
feature. By way or contrast, the ratings, if any, assigned to Municipal
Obligations insured under Portfolio Insurance will be based primarily upon the
credit characteristics of the issuers without regard to the insurance feature,
and will generally carry a rating that is below Aaa or AAA. While in the
portfolio of the Fund, however, a Municipal Obligation backed by Portfolio
Insurance will effectively be of the same quality as a Municipal Obligation
issued by
                                       B-4
<PAGE>   159
 
an issuer of comparable credit characteristics that is backed by Original Issue
Insurance or Secondary Market Insurance.
 
     The Fund's policy of investing in Municipal Obligations insured by insurers
whose claims-paying ability is rated Aaa or AAA will apply only at the time of
the purchase of a security, and a Fund will not be required to dispose of
securities in the event Moody's or S&P, as the case may be, downgrades its
assessment of the claims-paying ability of a particular insurer or the credit
characteristics of a particular issuer. In this connection, it should be noted
that in the event Moody's or S&P or both should down-grade its assessment of the
claims-paying ability of a particular insurer, it could also be expected to
downgrade the ratings assigned to Municipal Obligations insured under Original
Issue Insurance or Secondary Market Insurance issued by such insurer, and
Municipal Obligations insured under Portfolio Insurance issued by such insurer
would also be of reduced quality in the portfolio of the Fund. Moody's and S&P
continually assess the claims-paying ability of insurers and the credit
characteristics of issuers, and there can be no assurance that they will not
downgrade their assessments subsequent to the time the Fund purchases
securities.
 
     In addition to insured Municipal Obligations, the Fund may invest in
Municipal Obligations that are entitled to the benefit of an escrow or trust
account which contains securities issued or guaranteed by the U.S. Government or
U.S. Government agencies, backed by the full faith and credit of the United
States, and sufficient in amount to ensure the payment of interest and principal
on the original interest payment and maturity dates ("collateralized
obligations"). These collateralized obligations generally will not be insured
and will include, but are not limited to, Municipal Obligations that have been
(1) advance refunded where the proceeds of the refunding have been used to
purchase U.S. Government or U.S. Government agency securities that are placed in
escrow and whose interest or maturing principal payments, or both, are
sufficient to cover the remaining scheduled debt service on the Municipal
Obligations, and (2) issued under state or local housing finance programs which
use the issuance proceeds to fund mortgages that are then exchanged for U.S.
Government or U.S. Government agency securities and deposited with a trustee as
security for the Municipal Obligations. These collateralized obligations are
normally regarded as having the credit characteristics of the underlying U.S.
Government or U.S. Government agency securities. Collateralized obligations will
not constitute more than 20% of the Fund's assets.
 
     Each insured Municipal Obligation in which the Fund invests will be covered
by Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance.
There is no limitation on the percentage of the Fund's assets that may be
invested in Municipal Obligations insured by any given insurer.
 
     Original Issue Insurance. Original Issue Insurance is purchased with
respect to a particular issue of Municipal Obligations by the issuer thereof or
a third party in conjunction with the original issuance of such Municipal
Obligations. Under such insurance, the insurer unconditionally guarantees to the
holder of the Municipal Obligation the timely payment of principal and interest
on such obligation when and as such payments shall become due but shall not be
paid by the issuer, except that in the event of any acceleration of the due date
of the principal by reason of mandatory or optional redemption (other than
acceleration by reason of a mandatory sinking fund payment), default or
otherwise, the payments guaranteed may be made in such amounts and at such times
as payments of principal would have been due had there not been such
acceleration. The insurer is responsible for such payments less any amounts
received by the holder from any trustee for the Municipal Obligation issuers or
from any other source. Original Issue Insurance does not guarantee payment on an
accelerated basis, the payment of any redemption premium (except with respect to
certain premium payments in the case of certain small issue industrial
development and pollution control Municipal Obligations), the value of the
shares of the Fund, the market value of Municipal Obligations, or payments of
any tender purchase price upon the tender of the Municipal Obligations. Original
Issue Insurance also does not insure against nonpayment of principal of or
interest on Municipal Obligations resulting from the insolvency, negligence or
any other act or omission of the trustee or other paying agent for such
obligations.
 
     In the event that interest on or principal of a Municipal Obligation
covered by insurance is due for payment but is unpaid by the issuer thereof, the
applicable insurer will make payments to its fiscal agent (the "Fiscal Agent")
equal to such unpaid amounts of principal and interest not later than one
business day after the insurer has been notified that such nonpayment has
occurred (but not earlier than the date such payment is due). The Fiscal Agent
will disburse to the Fund the amount of principal and interest which is then due
for payment but is unpaid upon receipt by the Fiscal Agent of (i) evidence of
the Fund's right to receive payment of such principal and interest and (ii)
evidence, including any appropriate instruments of assignment, that all of the
rights to payment of such principal or interest then due for payment shall
thereupon vest in the insurer. Upon payment by the insurer of any principal or
interest payments with respect to any Municipal Obligations, the insurer shall
succeed to the rights of the Fund with respect to such payment.
 
                                       B-5
<PAGE>   160
 
     Original Issue Insurance remains in effect as long as the Municipal
Obligations covered thereby remain outstanding and the insurer remains in
business, regardless of whether the Fund ultimately disposes of such Municipal
Obligations. Consequently, Original Issue Insurance may be considered to
represent an element of market value with respect to the Municipal Obligations
so insured, but the exact effect, if any, of this insurance on such market value
cannot be estimated.
 
     Secondary Market Insurance. Subsequent to the time of original issuance of
a Municipal Obligation, the Fund or a third party may, upon the payment of a
single premium, purchase insurance on such Municipal Obligation. Secondary
Market Insurance generally provides the same type of coverage as is provided by
Original Issue Insurance and remains in effect as long as the Municipal
Obligation covered thereby remain outstanding, the holder of such Municipal
Obligation does not voluntarily relinquish the Secondary Market Insurance and
the insurer remains in business, regardless of whether the Fund ultimately
disposes of such Municipal Obligation.
 
     One of the purposes of acquiring Secondary Market Insurance with respect to
a particular Municipal Obligation would be to enable the Fund to enhance the
value of such Municipal Obligation. The Fund, for example, might seek to
purchase a particular Municipal Obligation and obtain Secondary Market Insurance
with respect thereto if, in the opinion of Nuveen Advisory, the market value of
such Municipal Obligation, as insured, would exceed the current value of the
Municipal Obligation without insurance plus the cost of the Secondary Market
Insurance. Similarly, if the Fund owns but wishes to sell a Municipal Obligation
that is then covered by Portfolio Insurance, the Fund might seek to obtain
Secondary Market Insurance with respect thereto if, in the opinion of Nuveen
Advisory, the net proceeds of a sale by the Fund of such obligation, as insured,
would exceed the current value of such obligation plus the cost of the Secondary
Market Insurance.
 
     Portfolio Insurance. Portfolio Insurance guarantees the payment of
principal and interest on specified eligible Municipal Obligations purchased by
the Fund. Except as described below, Portfolio Insurance generally provides the
same type of coverage as is provided by Original Issue Insurance or Secondary
Market Insurance. Municipal Obligations insured under one Portfolio Insurance
policy would generally not be insured under any other policy purchased by the
Fund. A Municipal Obligation is eligible for coverage under a policy if it meets
certain requirements of the insurer. Portfolio Insurance is intended to reduce
financial risk, but the cost thereof and compliance with investment restrictions
imposed under the policy will reduce the yield to shareholders of the Fund.
 
     If a Municipal Obligation is already covered by Original Issue Insurance or
Secondary Market Insurance, then such Municipal Obligation is not required to be
additionally insured under any policy of Portfolio Insurance that the Fund may
purchase. All premiums respecting Municipal Obligations covered by Original
Issue Insurance or Secondary Market Insurance are paid in advance by the issuer
or other party obtaining the insurance.
 
     Portfolio Insurance policies are effective only as to Municipal Obligations
owned by and held by the Fund, and do not cover Municipal Obligations for which
the contract for purchase fails. A "when-issued" Municipal Obligation will be
covered under a Portfolio Insurance policy upon the settlement date of the issue
of such "when-issued" Municipal Obligation. In determining whether to insure
Municipal Obligations held by the Fund, an insurer will apply its own standards,
which correspond generally to the standards it has established for determining
the insurability of new issues of Municipal Obligations. See "Original Issue
Insurance" above.
 
     Each Portfolio Insurance policy will be noncancellable and will remain in
effect so long as the Fund is in existence, the Municipal Obligations covered by
the policy continue to be held by the Fund, and the Fund pays the premiums for
the policy. Each insurer will generally reserve the right at any time upon 90
days' written notice to the Fund to refuse to insure any additional securities
purchased by the Fund after the effective date of such notice. The Board of
Trustees will generally reserve the right to terminate each policy upon seven
days' written notice to an insurer if it determines that the cost of such policy
is not reasonable in relation to the value of the insurance to the Fund.
 
     Each Portfolio Insurance policy will terminate as to any Municipal
Obligation that has been redeemed from or sold by the Fund on the date of such
redemption or the settlement date of such sale, and an insurer shall not have
any liability thereafter under a policy as to any such Municipal Obligation,
except that if the date of such redemption or the settlement date of such sale
occurs after a record date and before the related payment date with respect to
any such Municipal Obligation, the policy will terminate as to such Municipal
Obligation on the business day immediately following such payment date. Each
policy will terminate as to all Municipal Obligations covered thereby on the
date on which the last of the covered Municipal Obligations mature, are redeemed
or are sold by the Fund.
 
     One or more policies of Portfolio Insurance may provide a Fund, pursuant to
an irrevocable commitment of the insurer, with the option to exercise the right
to obtain permanent insurance ("Permanent Insurance") with respect
                                       B-6
<PAGE>   161
 
to a Municipal Obligation that is to be sold by the Fund. The Fund would
exercise the right to obtain Permanent Insurance upon payment of a single,
predetermined insurance premium payable from the proceeds of the sale of such
Municipal Obligation. It is expected that the Fund will exercise the right to
obtain Permanent Insurance for a Municipal Obligation only if, in the opinion of
Nuveen Advisory, upon such exercise the net proceeds from the sale by the Fund
of such obligation, as insured, would exceed the proceeds from the sale of such
obligation without insurance.
 
     The Permanent Insurance premium with respect to each such obligation is
determined based upon the insurability of each such obligation as of the date of
purchase by the Fund and will not be increased or decreased for any change in
the creditworthiness of such obligation unless such obligation is in default as
to payment or principal or interest, or both. In such event, the Permanent
Insurance premium shall be subject to an increase predetermined at the date of
purchase by the Fund.
 
     The Fund generally intends to retain any insured securities covered by
Portfolio Insurance that are in default or in significant risk of default and to
place a value on the insurance, which ordinarily will be the difference between
the market value of the defaulted security and the market value of similar
securities of minimum investment grade (i.e., rated BBB) that are not in
default. In certain circumstances, however, Nuveen Advisory may determine that
an alternative value for the insurance, such as the difference between the
market value of the defaulted security and either its par value or the market
value of securities of a similar nature that are not in default or in
significant risk of default, is more appropriate. To the extent that the Fund
holds such defaulted securities, it may be limited in its ability to manage its
investment portfolio and to purchase other Municipal Obligations. Except as
described above with respect to securities covered by Portfolio Insurance that
are in default or subject to significant risk of default, the Funds will not
place any value on the insurance in valuing the Municipal Obligations that it
holds.
 
     Because each Portfolio Insurance policy will terminate as to Municipal
Obligations sold by the Fund on the date of sale, in which event the insurer
will be liable only for those payments of principal and interest that are then
due and owing (unless Permanent Insurance is obtained by the Fund), the
provision for this insurance will not enhance the marketability of securities
held by the Fund, whether or not the securities are in default or in significant
risk of default. On the other hand, since Original Issue Insurance and Secondary
Market Insurance generally will remain in effect as long as Municipal
Obligations covered thereby are outstanding, such insurance may enhance the
marketability of such securities, even when such securities are in default or in
significant risk of default, but the exact effect, if any, on marketability
cannot be estimated. Accordingly, the Funds may determine to retain or,
alternatively, to sell Municipal Obligations covered by Original Issue Insurance
or Secondary Market Insurance that are in default or in significant risk of
default.
 
     Premiums for a Portfolio Insurance policy are paid monthly, and are
adjusted for purchases and sales of Municipal Obligations covered by the policy
during the month. The yield on the Fund is reduced to the extent of the
insurance premiums it pays. Depending upon the characteristics of the Municipal
Obligations held by the Fund, the annual premium rate for policies of Portfolio
Insurance is estimated to range from .15% to .30% of the value of the Municipal
Obligations covered under the policy. Because the majority of the Municipal
Obligations in the Fund were not covered by policies of Portfolio Insurance
during the year ended February 29, 1996, premium expenses as a percentage of the
value of Municipal Obligations held by the Fund for such period were .00%.
 
     Set forth below is information about the various municipal bond insurers
with whom the Nuveen Insured Municipal Bond Fund currently maintains policies of
Portfolio Insurance.
 
  AMBAC Indemnity Corporation ("AMBAC Indemnity")
 
     AMBAC Indemnity is a Wisconsin-domiciled stock insurance corporation
regulated by the Office of the Commissioner of Insurance of the State of
Wisconsin and licensed to do business in 50 states, the District of Columbia,
the Territory of Guam and the Commonwealth of Puerto Rico, with admitted assets
of approximately $2,642,000,000 (unaudited) and statutory capital of
approximately $1,509,000,000 (unaudited) as of March 31, 1997. Statutory capital
consists of AMBAC Indemnity's policyholders' surplus and statutory contingency
reserve. AMBAC Indemnity is a wholly-owned subsidiary of AMBAC, Inc., a 100%
publicly-held company. Moody's, S&P and Fitch Investors Service, L.P., each have
assigned a triple-A claims-paying ability rating to AMBAC Indemnity.
 
     AMBAC Indemnity has obtained a ruling from the Internal Revenue Service to
the effect that the insuring of an obligation by AMBAC Indemnity will not affect
the treatment for federal income tax purposes of interest on such obligation and
that insurance proceeds representing maturing interest paid by AMBAC Indemnity
under policy provisions substantially identical to those contained in its
municipal bond insurance policy shall be treated for federal income tax purposes
in the same manner as if such payments were made by the issuer of the bonds.

  MBIA Insurance Corporation ("MBIA")
 
     The Insurer is the principal operating subsidiary of MBIA Inc., a New York
Stock Exchange listed company. MBIA Inc. is not obligated to pay the debts of or
claims against the Insurer. The Insurer is domiciled in the State of New York
and licensed to do business in and subject to regulation under the laws of all
50 states, the District of Columbia, the Commonwealth of Puerto Rico, the
Commonwealth of the Northern Mariana Islands, the Virgin Islands of the United
States and the Territory of Guam. The Insurer has two European branches, one in
the Republic of France and the other in the Kingdom of Spain. New York has laws
prescribing minimum capital requirements, limiting classes and concentrations of
investments and requiring the approval of policy rates and forms. State laws
also regulate the amount of both the aggregate and individual risks that may be
insured, the payment of dividends by the Insurer, changes in control and
transactions among affiliates. Additionally, the Insurer is required to maintain
contingency reserves on its liabilities in certain amounts and for certain
periods of time.
 
     As of December 31, 1996 the Insurer had admitted assets of $4.4 billion
(audited), total liabilities of $3.0 billion (audited), and total capital and
surplus of $1.4 billion (audited) determined in accordance with statutory
accounting practices prescribed or permitted by insurance regulatory
authorities. As of March 31, 1997, the Insurer had admitted assets of $4.5
billion (unaudited), total liabilities of $3.0 billion (unaudited), and total
capital and surplus of $1.5 billion (unaudited) determined in accordance with
statutory accounting practices prescribed or permitted by insurance regulatory
authorities.
 
     Furthermore, copies of the Insurer's year end financial statements prepared
in accordance with statutory accounting practices are available without charge
from the Insurer. A copy of the Annual Report on Form 10-K of MBIA Inc. is
available from the Insurer or the Securities and Exchange Commission. The
address of the Insurer is 113 King Street, Armonk, New York 10504. The telephone
number of the Insurer is (914) 273-4545.
 
     The Insurer's policy unconditionally and irrevocably guarantees to the
Nuveen Insured Municipal Bond Fund the full and complete payment required to be
made by or on behalf of the issuer to the applicable paying agent or its
successor of an amount equal to (i) the principal of (either at the stated
maturity or by advancement of maturity pursuant to a mandatory sinking fund
payment) and interest on, the Municipal Obligations as such payments shall
become due but shall not be so paid (except that in the event of any
acceleration of the due date of such principal by reason of mandatory or
optional redemption or acceleration resulting from default or otherwise, other
than any advancement of maturity pursuant to a mandatory sinking fund payment,
the payments guaranteed by the Insurer's policy shall be made in such amounts
and at such times as such payments of principal would have been due had there
not been any such acceleration) and (ii) the reimbursement of any such payment
which is subsequently recovered from the Fund pursuant to a final judgment by a
court of competent jurisdiction that such payment constitutes an avoidable
preference to the Fund within the meaning of any applicable bankruptcy law (a
"Preference").
                                       B-8
<PAGE>   163
 
     The Insurer's policy does not insure against loss of any prepayment premium
which may at any time be payable with respect to any Municipal Obligation. The
Insurer's policy does not, under any circumstance, insure against loss relating
to: (i) optional or mandatory redemptions (other than mandatory sinking fund
redemptions); (ii) any payments to be made on an accelerated basis; (iii)
payments of the purchase price of Municipal Obligations upon tender thereof; or
(iv) any Preference relating to (i) through (iii) above. The Insurer's policy
also does not insure against nonpayment of principal of or interest on the
Municipal Obligations resulting from the insolvency, negligence or any other act
or omission of any paying agent for the Municipal Obligations.
 
     With respect to small issue industrial development bonds and pollution
control revenue bonds covered by the policy, the Insurer guarantees the full and
complete payments required to be made by or on behalf of an issuer of such bonds
if there occurs pursuant to the terms of the bonds an event which results in the
loss of the tax-exempt status of interest on such bonds, including principal,
interest or premium payments payable thereon, if any, as and when required to be
made by or on behalf of the issuer pursuant to the terms of such bonds.
 
     When the Insurer receives from the paying agent or the Fund, (1) telephonic
or telegraphic notice (subsequently confirmed in writing by registered or
certified mail), or (2) written notice by registered or certified mail, that a
required payment of any insured amount which is then due has not been made, the
Insurer on the due date of such payment or within one business day after receipt
of notice of such nonpayment, whichever is later, will make a deposit of funds,
in an account with State Street Bank and Trust Company, N.A., in New York, New
York, or its successor, sufficient for the payment of any such insured amounts
which are then due. Upon presentment and surrender of such Municipal Obligations
or presentment of such other proof of ownership of the Municipal Obligations,
together with any appropriate instruments of assignment to evidence the
assignment of the insured amounts due on the Municipal Obligations as are paid
by the Insurer, and appropriate instruments to effect the appointment of the
Insurer as agent for the Fund in any legal proceeding related to payment of
insured amounts on Municipal Obligations, such instruments being in a form
satisfactory to State Street Bank and Trust Company, N.A., State Street Bank and
Trust Company, N.A. shall disburse to the Fund or the paying agent payment of
the insured amounts due on such Municipal Obligations, less any amount held by
the paying agent for the payment of such insured amounts and legally available
therefor.
 
  Financial Guaranty Insurance Company ("Financial Guaranty")
 
     The Portfolio Insurance Policy is non-cancellable except for failure to pay
the premium. The premium rate for each purchase of a security covered by the
Portfolio Insurance Policy is fixed for the life of the Insured Bond. The
insurance premiums are payable monthly by the Fund and are adjusted for
purchases, sales and payments prior to maturity of Insured Bonds during the
month. In the event of a sale of any Insured Bond by the Fund or payment thereof
prior to maturity, the Portfolio Insurance policy terminates as to such Insured
Bond.
 
     Under the provisions of the Portfolio Insurance Policy, Financial Guaranty
unconditionally and irrevocably agrees to pay to State Street Bank and Trust
Company, or its successor, as its agent (the "Fiscal Agent"), that portion of
the principal of and interest on the Insured Bonds which shall become due for
payment but shall be unpaid by reason of nonpayment by the issuer of the Insured
Bonds. The term "due for payment" means, when referring to the principal of an
Insured Bond, its stated maturity date or the date on which it shall have been
called for mandatory sinking fund redemption and does not refer to any earlier
date on which payment is due by reason of call for redemption (other than by
mandatory sinking fund redemption), acceleration or other advancement of
maturity and means, when referring to interest on an Insured Bond, the stated
date for payment of interest. In addition, the Portfolio Insurance Policy covers
nonpayment by the issuer that results from any payment of principal or interest
made by such issuer on the Insured Bond to the Fund which has been recovered
from the Fund or its shareholders pursuant to the United States Bankruptcy Code
by a trustee in bankruptcy in accordance with a final, nonappealable order of a
court having competent jurisdiction.
 
     Financial Guaranty will make such payments to the Fiscal Agent on the date
such principal or interest becomes due for payment or on the business day next
following the day on which Financial Guaranty shall have received notice of
nonpayment, whichever is later. The Fiscal Agent will disburse the Trustee the
face amount of principal and interest which is then due for payment but is
unpaid by reason of nonpayment by the issuer, but only upon receipt by the
Fiscal Agent of (i) evidence of the Trustee's right to receive payment of the
principal or interest due for payment and (ii) evidence, including any
appropriate instruments of assignment, that all of the rights to payment of such
principal or interest due for payment thereupon shall vest in Financial
Guaranty. Upon such disbursement, Financial Guaranty shall become the owner of
the Insured Bond, appurtenant coupon or right to payment of principal or
interest on such Insured Bond and shall be fully subrogated to all of the
Trustee's rights thereunder, including the right to payment, thereof.
 
                                       B-9
<PAGE>   164
 
     In determining whether to insure municipal securities held in the Fund,
Financial Guaranty will apply its own standards which are not necessarily the
same as the criteria used in regard to the selection of securities by the Fund.
 
     Certain of the municipal securities insured under the Portfolio Insurance
Policy may also be insured under an insurance policy obtained by the issuer of
such municipal securities. The premium for any insurance policy or policies
obtained by an issuer or Insured Bonds has been paid in advance by such issuer
and any such policy or policies are non-cancellable and will continue in force
so long as the Insured Bonds so insured are outstanding. Financial Guaranty has
also agreed, if requested by the Funds on or before the fifth day preceding the
1st day of any month, to insure to maturity Insured Bonds sold by the Trustee
during the month immediately following such request of the Funds. The premium
for any such insurance to maturity provided by Financial Guaranty is paid by the
Fund and any such insurance is non-cancellable and will continue in force so
long as the Bonds so insured are outstanding.
 
     Financial Guaranty is a wholly-owned subsidiary of FGIC Corporation (the
"Corporation"), a Delaware holding company. The Corporation is a subsidiary of
General Electric Capital Corporation. Financial Guaranty is a monoline financial
guaranty insurer domiciled in the State of New York and subject to regulation by
the State of New York Insurance Department. As of March 31, 1997, the total
capital and surplus of Financial Guaranty was approximately $1,123,724,061.
Financial Guaranty prepares financial statements on the basis of both statutory
accounting principles and generally accepted accounting principles. Copies of
such financial statements may be obtained by writing to Financial Guaranty at
115 Broadway, New York, New York 10006, Attention: Communications Department
(telephone number: (212) 312-3000) or to the New York State Insurance Department
at 160 West Broadway, 18th Floor, New York, New York 10013, Attention: Property
Companies Bureau (telephone number: (212) 602-0389).
 
     The policies of insurance obtained by the Fund from Financial Guaranty and
the negotiations in respect thereof represent the only relationship between
Financial Guaranty and the Fund. Otherwise neither Financial Guaranty nor its
parent, FGIC Corporation, or any affiliate thereof has any significant
relationship, direct or indirect, with the Fund or the Board of Trustees of the
Fund.
 
     The above municipal bond insurers have insurance claims-paying ability
ratings of AAA from S&P and Aaa from Moody's. Financial Guaranty also has an
insurance claims-paying ability rating of AAA from Fitch.
 
     An S&P insurance claims-paying ability rating is an assessment of an
operating insurance company's financial capacity to meet obligations under an
insurance policy in accordance with its terms. An insurer with an insurance
claims-paying ability rating of AAA has the highest rating assigned by S&P.
Capacity to honor insurance contracts is adjudged by S&P to be extremely strong
and highly likely to remain so over a long period of time. A Moody's insurance
claims-paying ability rating is an opinion of the ability of an insurance
company to repay punctually senior policyholder obligations and claims. An
insurer with an insurance claims-paying ability rating of Aaa is adjudged by
Moody's to be of the best quality. In the opinion of Moody's, the policy
obligations of an insurance company with an insurance claims-paying ability
rating of Aaa carry the smallest degree of credit risk and, while the financial
strength of these companies is likely to change, such changes as can be
visualized are most unlikely to impair the company's fundamentally strong
position.
 
     An insurance claims-paying ability rating by S&P or Moody's does not
constitute an opinion on any specific contract in that such an opinion can only
be rendered upon the review of the specific insurance contract. Furthermore, an
insurance claims-paying ability rating does not take into account deductibles,
surrender or cancellation penalties or the timeliness of payment, nor does it
address the ability of a company to meet nonpolicy obligations (i.e., debt
contracts).
 
     The assignment of ratings by S&P or Moody's to debt issues that are fully
or partially supported by insurance policies, contracts or guarantees is a
separate process form the determination of claims-paying ability ratings. The
likelihood of a timely flow of funds from the insurer to the trustee for the
bondholders is a key element in the rating determination for such debt issues.
 
     S&P's and Moody's ratings are not recommendations to buy, sell or hold the
Municipal Obligations insured by policies issued by AMBAC Indemnity, Financial
Security, MBIA or Financial Guaranty and such ratings may be subject to revision
or withdrawal at any time by the rating agencies. Any downward revision or
withdrawal of either or both ratings may have an adverse effect on the market
price of the Municipal Obligations insured by policies issued by AMBAC
Indemnity, Financial Security, MBIA or Financial Guaranty.

<PAGE>   165
 
     S&P's ratings of AMBAC Indemnity, Financial Security, MBIA and Financial
Guaranty should be evaluated independent of Moody's ratings. Any further
explanation as to the significance of the ratings may be obtained only from the
applicable rating agency. See Appendix A for more information about ratings by
Moody's, S&P, and Fitch.
 
PORTFOLIO TRADING AND TURNOVER
 
     The Funds will make changes in their investment portfolio from time to time
in order to take advantage of opportunities in the municipal market and to limit
exposure to market risk. The Funds may also engage to a limited extent in
short-term trading consistent with their investment objective. Securities may be
sold in anticipation of market decline or purchased in anticipation of market
rise and later sold. In addition, a security may be sold and another of
comparable quality purchased at approximately the same time to take advantage of
what Nuveen Advisory believes to be a temporary disparity in the normal yield
relationship between the two securities. Each Fund may make changes in its
investment portfolio in order to limit its exposure to changing market
conditions. Changes in a Fund's investments are known as "portfolio turnover."
While it is impossible to predict future portfolio turnover rates, the annual
portfolio turnover rate for each of the Funds is generally not expected to
exceed 75%. However, each Fund reserves the right to make changes in its
investments whenever it deems such action advisable and, therefore, a Fund's
annual portfolio turnover rate may exceed 75% in particular years depending upon
market conditions.
 
     The portfolio turnover rates for the Funds, for the 1996 fiscal year-end of
each Fund as a series of its predecessor entity (described above), and for the
1997 fiscal year-end, as indicated, were

** For the eleven months ended April 30, 1997.
 
WHEN-ISSUED SECURITIES
 
     Each Fund may purchase and sell Municipal Obligations on a when-issued or
delayed delivery basis. When-issued and delayed delivery transactions arise when
securities are purchased or sold with payment and delivery beyond the regular
settlement date. (When-issued transactions normally settle within 15-45 days.)
On such transactions the payment obligation and the interest rate are fixed at
the time the buyer enters into the commitment. The commitment to purchase
securities on a when-issued or delayed delivery basis may involve an element of
risk because the value of the securities is subject to market fluctuation, no
interest accrues to the purchaser prior to settlement of the transaction, and at
the time of delivery the market value may be less than cost. At the time a Fund
makes the commitment to purchase a Municipal Obligation on a when-issued or
delayed delivery basis, it will record the transaction and reflect the amount
due and the value of the security in determining its net asset value. Likewise,
at the time a Fund makes the commitment to sell a Municipal Obligation on a
delayed delivery basis, it will record the transaction and include the proceeds
to be received in determining its net asset value; accordingly, any fluctuations
in the value of the Municipal Obligation sold pursuant to a delayed delivery
commitment are ignored in calculating net asset value so long as the commitment
remains in effect. The Funds will maintain designated readily marketable assets
at least equal in value to commitments to purchase when-issued or delayed
delivery securities, such assets to be segregated by the Custodian specifically
for the settlement of such commitments. The Funds will only make commitments to
purchase Municipal Obligations on a when-issued or delayed delivery basis with
the intention of actually acquiring the securities, but the Funds reserve the
right to sell these securities before the settlement date if it is deemed
advisable. If a when-issued security is sold before delivery any gain or loss
would not be tax-exempt. The Funds commonly engage in when-issued transactions
in order to purchase or sell newly-issued Municipal Obligations, and may engage
in delayed delivery transactions in order to manage its operations more
effectively.

<PAGE>   166
 
HEDGING AND OTHER DEFENSIVE ACTIONS
 
     Each Fund may periodically engage in hedging transactions. Hedging is a
term used for various methods of seeking to preserve portfolio capital value by
offsetting price changes in one investment through making another investment
whose price should tend to move in the opposite direction. It may be desirable
and possible in various market environments to partially hedge the portfolio
against fluctuations in market value due to interest rate fluctuations by
investment in financial futures and index futures as well as related put and
call options on such instruments. Both parties entering into an index or
financial futures contract are required to post an initial deposit of 1% to 5%
of the total contract price. Typically, option holders enter into offsetting
closing transactions to enable settlement in cash rather than take delivery of
the position in the future of the underlying security. Each Fund will only sell
covered futures contracts, which means that the Fund segregates assets equal to
the amount of the obligations.
 
     These transactions present certain risks. In particular, the imperfect
correlation between price movements in the futures contract and price movements
in the securities being hedged creates the possibility that losses on the hedge
by a Fund may be greater than gains in the value of the securities in such
series' portfolio. In addition, futures and options markets may not be liquid in
all circumstances. As a result, in volatile markets, a Fund may not be able to
close out the transaction without incurring losses substantially greater than
the initial deposit. Finally, the potential daily deposit requirements in
futures contracts create an ongoing greater potential financial risk than do
options transactions, where the exposure is limited to the cost of the initial
premium. Losses due to hedging transactions will reduce yield. Net gains, if
any, from hedging and other portfolio transactions will be distributed as
taxable distributions to shareholders.
 
     No Fund will make any investment (whether an initial premium or deposit or
a subsequent deposit) other than as necessary to close a prior investment if,
immediately after such investment, the sum of the amount of its premiums and
deposits would exceed 5% of such series' net assets. Each series will invest in
these instruments only in markets believed by the investment adviser to be
active and sufficiently liquid. For further information regarding these
investment strategies and risks presented thereby, see Appendix B to this
Statement of Additional Information.
 
     Each Fund reserves the right for liquidity or defensive purposes (such as
thinness in the market for municipal securities or an expected substantial
decline in value of long-term obligations), to temporarily invest up to 20% of
its assets in obligations issued or guaranteed by the U.S. Government and its
agencies or instrumentalities, including up to 5% in adequately collateralized
repurchase agreements relating thereto. Interest on each instrument is taxable
for Federal income tax purposes and would reduce the amount of tax-free interest
payable to shareholders.
 
TEMPORARY INVESTMENTS
 
     The Prospectus discusses briefly the ability of the Funds to invest a
portion of their assets in federally tax-exempt or taxable "temporary
investments." Temporary investments will not exceed 20% of a Fund's assets
except when made for defensive purposes. The Funds will invest only in taxable
temporary investments that are either U.S. Government securities or are rated
within the highest grade by Moody's, S&P, or Fitch and mature within one year
from the date of purchase or carry a variable or floating rate of interest. See
Appendix A for more information about ratings by Moody's, S&P, and Fitch.
 
     The Funds may invest in the following federally tax-exempt temporary
investments:
 
     Bond Anticipation Notes (BANs) are usually general obligations of state and
local governmental issuers which are sold to obtain interim financing for
projects that will eventually be funded through the sale of long-term debt
obligations or bonds. The ability of an issuer to meet its obligations on its
BANs is primarily dependent on the issuer's access to the long-term municipal
bond market and the likelihood that the proceeds of such bond sales will be used
to pay the principal and interest on the BANs.
 
     Tax Anticipation Notes (TANs) are issued by state and local governments to
finance the current operations of such governments. Repayment is generally to be
derived from specific future tax revenues. Tax anticipation notes are usually
general obligations of the issuer. A weakness in an issuer's capacity to raise
taxes due to, among other things, a decline in its tax base or a rise in
delinquencies, could adversely affect the issuer's ability to meet its
obligations on outstanding TANs.
 
     Revenue Anticipation Notes (RANs) are issued by governments or governmental
bodies with the expectation that future revenues from a designated source will
be used to repay the notes. In general, they also constitute general obligations
of the issuer. A decline in the receipt of projected revenues, such as
anticipated revenues from another
 
                                      B-12
<PAGE>   167
 
level of government, could adversely affect an issuer's ability to meet its
obligations on outstanding RANs. In addition, the possibility that the revenues
would, when received, be used to meet other obligations could affect the ability
of the issuer to pay the principal and interest on RANs.
 
     Construction Loan Notes are issued to provide construction financing for
specific projects. Frequently, these notes are redeemed with funds obtained from
the Federal Housing Administration.
 
     Bank Notes are notes issued by local government bodies and agencies as
those described above to commercial banks as evidence of borrowings. The
purposes for which the notes are issued are varied but they are frequently
issued to meet short-term working capital or capital-project needs. These notes
may have risks similar to the risks associated with TANs and RANs.
 
     Tax-Exempt Commercial Paper (Municipal Paper) represents very short-term
unsecured, negotiable promissory notes, issued by states, municipalities and
their agencies. Payment of principal and interest on issues of municipal paper
may be made from various sources, to the extent the funds are available
therefrom. Maturities of municipal paper generally will be shorter than the
maturities of TANs, BANs or RANs. There is a limited secondary market for issues
of municipal paper.
 
     Certain Municipal Obligations may carry variable or floating rates of
interest whereby the rate of interest is not fixed, but varies with changes in
specified market rates or indices, such as a bank prime rate or a tax-exempt
money market index.
 
     While these various types of notes as a group represent the major portion
of the tax-exempt note market, other types of notes are occasionally available
in the marketplace and the Fund may invest in such other types of notes to the
extent permitted under its investment objective, policies and limitations. Such
notes may be issued for different purposes and may be secured differently from
those mentioned above.
 
     The Funds may also invest in the following taxable temporary investments:
 
     U.S. Government Direct Obligations are issued by the United States Treasury
and include bills, notes and bonds.
 
     -- Treasury bills are issued with maturities of up to one year. They are
        issued in bearer form, are sold on a discount basis and are payable at
        par value at maturity.
 
     -- Treasury notes are longer-term interest bearing obligations with
        original maturities of one to seven years.
 
     -- Treasury bonds are longer-term interest-bearing obligations with
        original maturities from five to thirty years.
 
     U.S. Government Agencies Securities--Certain federal agencies have been
established as instrumentalities of the United States Government to supervise
and finance certain types of activities. These agencies include, but are not
limited to, the Bank for Cooperatives, Federal Land Banks, Federal Intermediate
Credit Banks, Federal Home Loan Banks, Federal National Mortgage Association,
Government National Mortgage Association, Export-Import Bank of the United
States, and Tennessee Valley Authority. Issues of these agencies, while not
direct obligations of the United States Government, are either backed by the
full faith and credit of the United States or are guaranteed by the Treasury or
supported by the issuing agencies' right to borrow from the Treasury. There can
be no assurance that the United States Government itself will pay interest and
principal on securities as to which it is not legally so obligated.
 
     Certificates of Deposit (CDs)--A certificate of deposit is a negotiable
interest bearing instrument with a specific maturity. CDs are issued by banks in
exchange for the deposit of funds and normally can be traded in the secondary
market, prior to maturity. The Fund will only invest in U.S. dollar denominated
CDs issued by U.S. banks with assets of $1 billion or more.
 
     Commercial Paper--Commercial paper is the term used to designate unsecured
short-term promissory notes issued by corporations. Maturities on these issues
vary from a few days to nine months. Commercial paper may be purchased from U.S.
corporations.
 
     Other Corporate Obligations--The Funds may purchase notes, bonds and
debentures issued by corporations if at the time of purchase there is less than
one year remaining until maturity or if they carry a variable or floating rate
of interest.
 
     Repurchase Agreements -- A repurchase agreement is a contractual agreement
whereby the seller of securities (U.S. Government or Municipal Obligations)
agrees to repurchase the same security at a specified price on a future
 
                                      B-13
<PAGE>   168
 
date agreed upon by the parties. The agreed upon repurchase price determines the
yield during a Fund's holding period. Repurchase agreements are considered to be
loans collateralized by the underlying security that is the subject of the
repurchase contract. The Funds will only enter into repurchase agreements with
dealers, domestic banks or recognized financial institutions that in the opinion
of Nuveen Advisory present minimal credit risk. The risk to the Funds is limited
to the ability of the issuer to pay the agreed-upon repurchase price on the
delivery date; however, although the value of the underlying collateral at the
time the transaction is entered into always equals or exceeds the agreed-upon
repurchase price, if the value of the collateral declines there is a risk of
loss of both principal and interest. In the event of default, the collateral may
be sold but a Fund might incur a loss if the value of the collateral declines,
and might incur disposition costs or experience delays in connection with
liquidating the collateral. In addition, if bankruptcy proceedings are commenced
with respect to the seller of the security, realization upon the collateral by a
Fund may be delayed or limited. Nuveen Advisory will monitor the value of
collateral at the time the transaction is entered into and at all times
subsequent during the term of the repurchase agreement in an effort to determine
that the value always equals or exceeds the agreed upon price. In the event the
value of the collateral declined below the repurchase price, Nuveen Advisory
will demand additional collateral from the issuer to increase the value of the
collateral to at least that of the repurchase price. Each of the Funds will not
invest more than 10% of its assets in repurchase agreements maturing in more
than seven days.

     In addition to the management fee of Nuveen Advisory, each Fund pays all
other costs and expenses of its operations and a portion of the Trust's general
administrative expenses allocated in proportion to the net assets of each Fund.
 
     Nuveen Advisory is a wholly owned subsidiary of John Nuveen & Co.
Incorporated ("Nuveen"), the Funds' principal underwriter. In 1961, Nuveen began
sponsoring the Nuveen Tax-Exempt Unit Trust and since that time has issued more
than $36 billion in tax-exempt unit trusts, including over $12 billion in
tax-exempt insured unit trusts. In addition, Nuveen open-end and closed-end
funds held approximately $36 billion in tax-exempt securities under management
as of the date of this Statement. Over 1,000,000 individuals have invested to
date in Nuveen's tax-exempt funds and trusts. Founded in 1898, 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 in St. Paul,
Minnesota and is principally engaged in providing property-liability insurance
through subsidiaries. Effective January 1, 1997, The John Nuveen Company
acquired Flagship Resources Inc., and as part of that acquisition, Flagship
Financial, the adviser to the Flagship Funds, was merged with Nuveen Advisory.
 
     Nuveen Advisory's portfolio managers call upon the resources of Nuveen's
Research Department. The Nuveen Research Department reviews more than $100
billion in municipal bonds every year.
 
     The Funds, the other Nuveen funds, Nuveen Advisory, and other related
entities have adopted a code of ethics which essentially prohibits all Nuveen
fund management personnel, including Nuveen fund portfolio managers, from
engaging in personal investments which compete or interfere with, or attempt to
take advantage of, a Fund's anticipated or actual portfolio transactions, and is
designed to assure that the interests of Fund shareholders are placed before the
interests of Nuveen personnel in connection with personal investment
transactions.
 
                             PORTFOLIO TRANSACTIONS
 
     Nuveen Advisory, in effecting purchases and sales of portfolio securities
for the account of each Fund, will place orders in such manner as, in the
opinion of management, will offer the best price and market for the execution of
each transaction. Portfolio securities will normally be purchased directly from
an underwriter or in the over-the-counter market from the principal dealers in
such securities, unless it appears that a better price or execution may be
obtained elsewhere. Portfolio securities will not be purchased from Nuveen or
its affiliates except in compliance with the Investment Company Act of 1940.
 
                                      B-21
<PAGE>   176
 
     The Funds expect that all portfolio transactions will be effected on a
principal (as opposed to an agency) basis and, accordingly, do not expect to pay
any brokerage commissions. Purchases from underwriters will include a commission
or concession paid by the issuer to the underwriter, and purchases from dealers
will include the spread between the bid and asked price. Given the best price
and execution obtainable, it will be the practice of the Funds to select dealers
which, in addition, furnish research information (primarily credit analyses of
issuers and general economic reports) and statistical and other services to
Nuveen Advisory. It is not possible to place a dollar value on information and
statistical and other services received from dealers. Since it is only
supplementary to Nuveen Advisory's own research efforts, the receipt of research
information is not expected to reduce significantly Nuveen Advisory's expenses.
While Nuveen Advisory will be primarily responsible for the placement of the
business of the Funds, the policies and practices of Nuveen Advisory in this
regard must be consistent with the foregoing and will, at all times, be subject
to review by the Board of Trustees.
 
     Nuveen Advisory reserves the right to, and does, manage other investment
accounts and investment companies for other clients, which may have investment
objectives similar to the Funds. Subject to applicable laws and regulations,
Nuveen Advisory will attempt to allocate equitably portfolio transactions among
the Funds and the portfolios of its other clients purchasing or selling
securities whenever decisions are made to purchase or sell securities by a Fund
and one or more of such other clients simultaneously. In making such allocations
the main factors to be considered will be the respective investment objectives
of the Fund and such other clients, the relative size of portfolio holdings of
the same or comparable securities, the availability of cash for investment by
the Fund and such other clients, the size of investment commitments generally
held by the Fund and such other clients and opinions of the persons responsible
for recommending investments to the Fund and such other clients. While this
procedure could have a detrimental effect on the price or amount of the
securities available to a Fund from time to time, it is the opinion of the Board
of Trustees that the benefits available from Nuveen Advisory's organization will
outweigh any disadvantage that may arise from exposure to simultaneous
transactions.
 
     Under the Investment Company Act of 1940, the Funds may not purchase
portfolio securities from any underwriting syndicate of which Nuveen is a member
except under certain limited conditions set forth in Rule 10f-3. The Rule sets
forth requirements relating to, among other things, the terms of an issue of
Municipal Obligations purchased by a Fund, the amount of Municipal Obligations
which may be purchased in any one issue and the assets of a Fund which may be
invested in a particular issue. In addition, purchases of securities made
pursuant to the terms of the Rule must be approved at least quarterly by the
Board of Trustees, including a majority of the trustees who are not interested
persons of the Trust.
 
                                NET ASSET VALUE
 
     As stated in the Prospectus, the net asset value of the shares of the Funds
will be determined separately for each class of the Funds' shares by The Chase
Manhattan Bank, the Funds' custodian, as of the close of trading (normally 4:00
p.m. Eastern Time) on each day on which the New York Stock Exchange (the
"Exchange") is normally open for trading. The Exchange is not open for trading
on New Year's Day, Washington's Birthday, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The net asset
value per share of a class of shares of a Fund will be computed by dividing the
value of the Fund's assets attributable to the class, less the liabilities
attributable to the class, by the number of shares of the class outstanding.
 
     In determining net asset value for the Funds, each Fund's custodian
utilizes the valuations of portfolio securities furnished by a pricing service
approved by the trustees. Securities for which quotations are not readily
available (which constitute a majority of the securities held by the Funds) are
valued at fair value as determined by the pricing service using methods which
include consideration of the following: yields or prices of municipal bonds of
comparable quality, type of issue, coupon, maturity and rating; indications as
to value from dealers; and general market conditions. The pricing service may
employ electronic data processing techniques and/or a matrix system to determine
valuations. The procedures of the pricing service and its valuations are
reviewed by the officers of the Trust under the general supervision of the Board
of Trustees.
 
                                  TAX MATTERS
 
FEDERAL INCOME TAX MATTERS
 
     The following discussion of federal income tax matters is based upon the
advice of Fried, Frank, Harris, Shriver & Jacobson, counsel to the Trust.
 
                                      B-22
<PAGE>   177
 
     Each Fund intends to qualify under Subchapter M of the Internal Revenue
Code of 1986, as amended (the "Code") for tax treatment as a regulated
investment company. In order to qualify as a regulated investment company, a
Fund must satisfy certain requirements relating to the source of its income,
diversification of its assets, and distributions of its income to shareholders.
First, a Fund must derive at least 90% of its annual gross income (including
tax-exempt interest) from dividends, interest, payments with respect to
securities loans, gains from the sale or other disposition of stock or
securities, foreign currencies or other income (including but not limited to
gains from options and futures) derived with respect to its business of
investing in such stock or securities (the "90% gross income test"). Second, a
Fund must derive less than 30% of its annual gross income from the sale or other
disposition of any of the following which was held for less than three months:
(i) stock or securities and (ii) certain options, futures, or forward contracts
(the "short-short test"). Third, a Fund must diversify its holdings so that, at
the close of each quarter of its taxable year, (i) at least 50% of the value of
its total assets is comprised of cash, cash items, United States Government
securities, securities of other regulated investment companies and other
securities limited in respect of any one issuer to an amount not greater in
value than 5% of the value of a Fund's total assets and to not more than 10% of
the outstanding voting securities of such issuer, and (ii) not more than 25% of
the value of the total assets is invested in the securities of any one issuer
(other than United States Government securities and securities of other
regulated investment companies) or two or more issuers controlled by a Fund and
engaged in the same, similar or related trades or businesses.
 
     As a regulated investment company, a Fund will not be subject to federal
income tax in any taxable year for which it distributes at least 90% of the sum
of (i) its "investment company taxable income" (which includes dividends,
taxable interest, taxable original issue discount and market discount income,
income from securities lending, net short-term capital gain in excess of
longterm capital loss, and any other taxable income other than "net capital
gain" (as defined below) and is reduced by deductible expenses) and (ii) its net
taxexempt interest (the excess of its gross tax-exempt interest income over
certain disallowed deductions). A Fund may retain for investment its net capital
gain (which consists of the excess of its net long-term capital gain over its
short-term capital loss). However, if a Fund retains any net capital gain or any
investment company taxable income, it will be subject to tax at regular
corporate rates on the amount retained. If a Fund retains any capital gain, such
Fund may designate the retained amount as undistributed capital gains in a
notice to its shareholders who, if subject to federal income tax on long-term
capital gains, (i) will be required to include in income for federal income tax
purposes, as long-term capital gain, their shares of such undistributed amount,
and (ii) will be entitled to credit their proportionate shares of the tax paid
by such Fund against their federal income tax liabilities if any, and to claim
refunds to the extent the credit exceeds such liabilities. For federal income
tax purposes, the tax basis of shares owned by a shareholder of the Fund will be
increased by an amount equal under current law to 65% of the amount of
undistributed capital gains included in the shareholder's gross income. Each
Fund intends to distribute at least annually to its shareholders all or
substantially all of its net tax-exempt interest and any investment company
taxable income and net capital gain.
 
     Treasury regulations permit a regulated investment company, in determining
its investment company taxable income and net capital gain, i.e., the excess of
net long-term capital gain over net short-term capital loss for any taxable
year, to elect (unless it has made a taxable year election for excise tax
purposes as discussed below) to treat all or part of any net capital loss, any
net long-term capital loss or any net foreign currency loss incurred after
October 31 as if they had been incurred in the succeeding year.
 
     Each Fund also intends to satisfy conditions (including requirements as to
the proportion of its assets invested in Municipal Obligations) that will enable
it to designate distributions from the interest income generated by investments
in Municipal Obligations, which is exempt from regular federal income tax when
received by such Fund, as exempt-interest dividends. Shareholders receiving
exempt-interest dividends will not be subject to regular federal income tax on
the amount of such dividends. Insurance proceeds received by a Fund under any
insurance policies in respect of scheduled interest payments on defaulted
Municipal Obligations will be excludable from federal gross income under Section
103(a) of the Code. In the case of non-appropriation by a political subdivision,
however, there can be no assurance that payments made by the insurer
representing interest on "non-appropriation" lease obligations will be
excludable from gross income for federal income tax purposes. See "Investment
Policies and Investment Portfolio; Portfolio Securities."
 
     Distributions by a Fund of net interest received from certain taxable
temporary investments (such as certificates of deposit, commercial paper and
obligations of the U.S. Government, its agencies and instrumentalities) and net
short-term capital gains realized by a Fund, if any, will be taxable to
shareholders as ordinary income whether received in cash or additional shares.
If a Fund purchases a Municipal Obligation at a market discount, any gain
realized by the Fund upon sale or redemption of the Municipal Obligation will be
treated as taxable interest income to the extent such gain does not exceed the
market discount, and any gain realized in excess of the market
                                      B-23
<PAGE>   178
 
discount will be treated as capital gains. Any net long-term capital gains
realized by a Fund and distributed to shareholders in cash or additional shares,
will be taxable to shareholders as long-term capital gains regardless of the
length of time investors have owned shares of a Fund. Distributions by a Fund
that do not constitute ordinary income dividends, exempt-interest dividends, or
capital gain dividends will be treated as a return of capital to the extent of
(and in reduction of) the shareholder's tax basis in his or her shares. Any
excess will be treated as gain from the sale of his or her shares, as discussed
below.
 
     If a Fund has both tax-exempt and taxable income, it will use the "average
annual" method for determining the designated percentage that is taxable income
and designate the use of such method within 60 days after the end of the Fund's
taxable year. Under this method, one designated percentage is applied uniformly
to all distributions made during the Fund's taxable year. The percentage of
income designated as tax-exempt for any particular distribution may be
substantially different from the percentage of the Fund's income that was
taxexempt during the period covered by the distribution.
 
     If a Fund engages in hedging transactions involving financial futures and
options, these transactions will be subject to special tax rules, the effect of
which may be to accelerate income to a Fund, defer a Fund's losses, cause
adjustments in the holding periods of a Fund's securities, convert long-term
capital gains into short-term capital gains and convert short-term capital
losses into long-term capital losses. These rules could therefore affect the
amount, timing and character of distributions to shareholders.
 
     Because the taxable portion of a Fund's investment income consists
primarily of interest, none of its dividends, whether or not treated as
exempt-interest dividends, is expected to qualify under the Internal Revenue
Code for the dividends received deductions for corporations.
 
     Prior to purchasing shares in a Fund, the impact of dividends or
distributions which are expected to be or have been declared, but not paid,
should be carefully considered. Any dividend or distribution declared shortly
after a purchase of such shares prior to the record date will have the effect of
reducing the per share net asset value by the per share amount of the dividend
or distribution.
 
     Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in one of those months and paid during the following
January, will be treated as having been distributed by a Fund (and received by
the shareholders) on December 31.
 
     The redemption or exchange of the shares of a Fund normally will result in
capital gain or loss to the shareholders. Generally, a shareholder's gain or
loss will be long-term gain or loss if the shares have been held for more than
one year. Present law taxes both long- and short-term capital gains of
corporations at the rates applicable to ordinary income. For non-corporate
taxpayers, however, net capital gains (i.e., the excess of net long-term capital
gain over net short-term capital loss) will be taxed at a maximum marginal rate
of 28%, while short-term capital gains and other ordinary income will be taxed
at a maximum marginal rate of 39.6%. Because of the limitations on itemized
deductions and the deduction for personal exemptions applicable to higher income
taxpayers, the effective tax rate may be higher in certain circumstances.
 
     All or a portion of a sales charge paid in purchasing shares of a Fund
cannot be taken into account for purposes of determining gain or loss on the
redemption or exchange of such shares within 90 days after their purchase to the
extent shares of a Fund or another fund are subsequently acquired without
payment of a sales charge pursuant to the reinvestment or exchange privilege.
Any disregarded portion of such charge will result in an increase in the
shareholder's tax basis in the shares subsequently acquired. Moreover, losses
recognized by a shareholder on the redemption or exchange of shares of a Fund
held for six months or less are disallowed to the extent of any distribution of
exempt-interest dividends received with respect to such shares and, if not
disallowed, such losses are treated as long-term capital losses to the extent of
any distributions of long-term capital gains made with respect to such shares.
In addition, no loss will be allowed on the redemption or exchange of shares of
a Fund if the shareholder purchases other shares of such Fund (whether through
reinvestment of distributions or otherwise) or the shareholder acquires or
enters into a contract or option to acquire securities that are substantially
identical to shares of a Fund within a period of 61 days beginning 30 days
before and ending 30 days after such redemption or exchange. If disallowed, the
loss will be reflected in an adjustment to the basis of the shares acquired.
 
     It may not be advantageous from a tax perspective for shareholders to
redeem or exchange shares after tax-exempt income has accrued but before the
record date for the exempt-interest dividend representing the distribution of
such income. Because such accrued tax-exempt income is included in the net asset
value per share (which equals the redemption or exchange value), such a
redemption could result in treatment of the portion of the sales or
 
                                      B-24
<PAGE>   179
 
redemption proceeds equal to the accrued tax-exempt interest as taxable gain (to
the extent the redemption or exchange price exceeds the shareholder's tax basis
in the shares disposed of) rather than tax-exempt interest.
 
     In order to avoid a 4% federal excise tax, a Fund must distribute or be
deemed to have distributed by December 31 of each calendar year at least 98% of
its taxable ordinary income for such year, at least 98% of the excess of its
realized capital gains over its realized capital losses (generally computed on
the basis of the one-year period ending on October 31 of such year) and 100% of
any taxable ordinary income and the excess of realized capital gains over
realized capital losses for the prior year that was not distributed during such
year and on which such Fund paid no federal income tax. For purposes of the
excise tax, a regulated investment company may reduce its capital gain net
income (but not below its net capital gain) by the amount of any net ordinary
loss for the calendar year. The Funds intend to make timely distributions in
compliance with these requirements and consequently it is anticipated that they
generally will not be required to pay the excise tax.
 
     If in any year a Fund should fail to qualify under Subchapter M for tax
treatment as a regulated investment company, the Fund would incur a regular
corporate federal income tax upon its income for that year (other than interest
income from Municipal Obligations), and distributions to its shareholders would
be taxable to shareholders as ordinary dividend income for federal income tax
purposes to the extent of the Fund's available earnings and profits.
 
     Among the requirements that a Fund must meet in order to qualify under
Subchapter M in any year is that less than 30% of its gross income must be
derived from the sale or other disposition of securities and certain other
assets held for less than three months.
 
     Because the Funds may invest in private activity bonds, the interest on
which is not federally tax-exempt to persons who are "substantial users" of the
facilities financed by such bonds or "related persons" of such "substantial
users," the Funds may not be an appropriate investment for shareholders who are
considered either a "substantial user" or a "related person" within the meaning
of the Code. For additional information, investors should consult their tax
advisers before investing in a Fund.
 
     Federal tax law imposes an alternative minimum tax with respect to both
corporations and individuals. Interest on certain Municipal Obligations, such as
bonds issued to make loans for housing purposes or to private entities (but not
for certain tax-exempt organizations such as universities and non-profit
hospitals), is included as an item of tax preference in determining the amount
of a taxpayer's alternative minimum taxable income. To the extent that a Fund
receives income from Municipal Obligations subject to the alternative minimum
tax, a portion of the dividends paid by it, although otherwise exempt from
federal income tax, will be taxable to shareholders to the extent that their tax
liability is determined under the alternative minimum tax regime. The Funds will
annually supply shareholders with a report indicating the percentage of Fund
income attributable to Municipal Obligations subject to the federal alternative
minimum tax.
 
     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 the
alternative minimum taxable income. Interest on all Municipal Obligations, and
therefore all distributions by the Funds that would otherwise be tax-exempt, is
included in calculating a corporation's adjusted current earnings.
 
     Tax-exempt income, including exempt-interest dividends paid by a Fund, will
be added to the taxable income of individuals receiving social security or
railroad retirement benefits in determining whether a portion of that benefit
will be subject to federal income tax.
 
     The Code provides that interest on indebtedness incurred or continued to
purchase or carry shares of any Fund is not deductible. Under rules used by the
IRS for determining when borrowed funds are considered used for the purpose of
purchasing or carrying particular assets, the purchase of shares of a Fund may
be considered to have been made with borrowed funds even though such funds are
not directly traceable to the purchase of shares.
 
     The Funds are required in certain circumstances to withhold 31% of taxable
dividends and certain other payments paid to non-corporate holders of shares who
have not furnished to the Funds their correct taxpayer identification number (in
the case of individuals, their social security number) and certain
certifications, or who are otherwise subject to backup withholding.
 
     The foregoing is a general and abbreviated summary of the provisions of the
Code and Treasury Regulations presently in effect as they directly govern the
taxation of the Fund and its shareholders. For complete provisions, reference
should be made to the pertinent Code sections and Treasury Regulations. The Code
and Treasury Regulations are subject to change by legislative or administrative
action, and any such change may be retroactive
 
                                      B-25
<PAGE>   180
 
with respect to Fund transactions. Shareholders are advised to consult their own
tax advisers for more detailed information concerning the federal taxation of
the Funds and the income tax consequences to their shareholders.
 
                            PERFORMANCE INFORMATION
 
     The historical investment performance of the Funds may be shown in the form
of "yield," "taxable equivalent yield," "average annual total return,"
"cumulative total return" and "taxable equivalent total return" figures, each of
which will be calculated separately for each class of shares.
 
     In accordance with a standardized method prescribed by rules of the
Securities and Exchange Commission ("SEC"), yield is computed by dividing the
net investment income per share earned during the specified one month or 30-day
period by the maximum offering price per share on the last day of the period,
according to the following formula:
 
                                       a-b    6
                          Yield = 2 [( --- +1)  - 1]
                                       cd
 
     In the above formula, a = dividends and interest earned during the period;
b = expenses accrued for the period (net of reimbursements); c = the average
daily number of shares outstanding during the period that were entitled to
receive dividends; and d = the maximum offering price per share on the last day
of the period. In the case of Class A shares, the maximum offering price
includes the current maximum front-end sales charge of 4.2% (3.0% for the
Intermediate Municipal Bond Fund and 2.5% for the Limited Term Municipal Bond
Fund).
 
     In computing yield, the Funds follow certain standardized accounting
practices specified by SEC rules. These practices are not necessarily consistent
with those that the Funds use to prepare their annual and interim financial
statements in conformity with generally accepted accounting principles. Thus,
yield may not equal the income paid to shareholders or the income reported in a
Fund's financial statements.
 
     Taxable equivalent yield is computed by dividing that portion of the yield
which is tax-exempt by the remainder of (1 minus the stated federal income tax
rate, taking into account the deductibility of state taxes for federal income
tax purposes) and adding the product to that portion, if any, of the yield that
is not tax exempt.
 
     The taxable equivalent yields quoted below are based upon (1) the stated
federal income tax rate and (2) the yields for the 30-day period quoted in the
right hand column.

*  These rates do not reflect the current federal tax limitations on itemized
   deductions and personal exemptions, which may raise the effective tax rate
   and taxable equivalent yield for taxpayers above certain income levels.

Taxable Equivalent Yields table in the Prospectus.
 
     The Funds may from time to time in their advertising and sales materials
report a quotation of their current distribution rate. The distribution rate
represents a measure of dividends distributed for a specified period.
                                      B-26
<PAGE>   181
 
Distribution rate is computed by taking the most recent monthly tax-free income
dividend per share, multiplying it by 12 to annualize it, and dividing by the
appropriate price per share (e.g., net asset value for purchases to be made
without a load such as reinvestments from Nuveen UITs, or the maximum public
offering price). The distribution rate differs from yield and total return and
therefore is not intended to be a complete measure of performance. Distribution
rate may sometimes differ from yield because a Fund may be paying out more than
it is earning and because it may not include the effect of amortization of bond
premiums to the extent such premiums arise after the bonds were purchased.
 
     The distribution rates as of the period quoted, based on the maximum public
offering price then in effect for the Funds, and assuming the imposition of the
maximum sales charge for Class A Shares of 4.2% for the Municipal Bond Fund, the
Insured Municipal Bond Fund, and the All-American Fund; the maximum sales charge

     Average annual total return quotation is computed in accordance with a
standardized method prescribed by SEC rules. The average annual total return for
a specific period is found by taking a hypothetical, $1,000 investment ("initial
investment") in Fund shares on the first day of the period, reducing the amount
to reflect the maximum sales charge, and computing the "redeemable value" of
that investment at the end of the period. The redeemable value is then divided
by the initial investment, and this quotient is taken to the Nth root (N
representing the number of years in the period) and 1 is subtracted from the
result, which is then expressed as a percentage. The calculation assumes that
all income and capital gains distributions have been reinvested in Fund shares
at net asset value on the reinvestment dates during the period.
 
     Total returns for the oldest class of each fund reflect actual performance
for all periods. For other classes, total returns reflect actual performance for
periods since class inception, and the oldest class's performance for periods
prior to inception, adjusted for the differences in sales charges and fees
between the classes.
 
     The inception dates for each class of the Funds' shares are as follows:

     Calculation of cumulative total return is not subject to a prescribed
formula. Cumulative total return for a specific period is calculated by first
taking a hypothetical initial investment in Fund shares on the first day of the
period, deducting (in some cases) the maximum sales charge, and computing the
"redeemable value" of that investment at the end of the period. The cumulative
total return percentage is then determined by subtracting the initial investment
from the redeemable value and dividing the remainder by the initial investment
and expressing the result as a percentage. The calculation assumes that all
income and capital gains distributions by the Fund have been reinvested at net
asset value on the reinvestment dates during the period. Cumulative total return
may also be shown as the increased dollar value of the hypothetical investment
over the period. Cumulative total return calculations that do not include the
effect of the sales charge would be reduced if such charge were included.

the effect of the maximum sales charge for the Class A Shares, and applicable

     Calculation of taxable equivalent total return is also not subject to a
prescribed formula. Taxable equivalent total return for a specific period is
calculated by first taking a hypothetical initial investment in Fund shares on
the first day of the period, computing the total return for each calendar year
in the period in the manner described above, and increasing the total return for
each such calendar year by the amount of additional income that a taxable fund
would need to have generated to equal the income on an after-tax basis, at a
specified income tax rate (usually the highest marginal federal tax rate),
calculated as described above under the discussion of "taxable equivalent
yield." The resulting amount for the calendar year is then divided by the
initial investment amount to arrive at a "taxable equivalent total return
factor" for the calendar year. The taxable equivalent total return factors for
all the calendar years are then multiplied together and the result is then
annualized by taking its Nth root (N representing the number of years in the
period) and subtracting 1, which provides a taxable equivalent total return
expressed as a percentage.
 
     Using the 39.6% maximum marginal federal tax rate for 1997, the annual
taxable equivalent total return for the Nuveen Municipal Bond Fund's Class R
Shares for the ten year period ended April 30, 1997, was 12.02%.
 
     Class A Shares of the Funds are sold at net asset value plus a current
maximum sales charge of 4.20% of the offering price (3.0% for the Intermediate
Municipal Bond Fund and 2.5% for the Limited Term Municipal Bond Fund). This
current maximum sales charge will typically be used for purposes of calculating
performance figures. Yield, returns and net asset value of each class of shares
of the Funds will fluctuate. Factors affecting the performance of the Funds
include general market conditions, operating expenses and investment management.

additional fees charged by a securities representative or other financial
services firm would reduce returns described in this section. Shares of the
Funds are redeemable at net asset value, which may be more or less than original
cost.
 
     In reports or other communications to shareholders or in advertising and
sales literature, the Funds may also compare their performance with that of: (1)
the Consumer Price Index or various unmanaged bond indexes such as the Lehman
Brothers Municipal Bond Index and the Salomon Brothers High Grade Corporate Bond
Index and (2) other fixed income or municipal bond mutual funds or mutual fund
indexes as reported by Lipper Analytical Services, Inc. ("Lipper"), Morningstar,
Inc. ("Morningstar"), Wiesenberger Investment Companies Service ("Wiesenberger")
and CDA Investment Technologies, Inc. ("CDA") or similar independent services
which monitor the performance of mutual funds, or other industry or financial
publications such as Barron's, Changing Times, Forbes and Money Magazine.
Performance comparisons by these indexes, services or publications may rank
mutual funds over different periods of time by means of aggregate, average,
year-by-year, or other types of total return and performance figures. Any given
performance quotation or performance comparison should not be considered as
representative of the performance of the Funds for any future period.
 
     Each Fund may from time to time in its advertising and sales materials
compare its current yield or total return with the yield or total return on
taxable investments such as corporate or U.S. Government bonds, bank
certificates of deposit (CDs) or money market funds. These taxable investments
have investment characteristics that differ from those of the Funds. U.S.
Government bonds, for example, are long-term investments backed by the full
faith and credit of the U.S. Government, and bank CDs are generally short-term,
FDIC-insured investments, which pay fixed principal and interest but are subject
to fluctuating rollover rates. Money market funds are short-term investments
with stable net asset values, fluctuating yields and special features enhancing
liquidity.
 
     There are differences and similarities between the investments which the
Funds may purchase and the investments measured by the indexes and reporting
services which are described herein. The Consumer Price Index is generally
considered to be a measure of inflation. The CDA Mutual Fund-Municipal Bond
Index is a weighted performance average of other mutual funds with a federally
tax-exempt income objective. The Salomon Brothers High Grade Corporate Bond
Index is an unmanaged index that generally represents the performance of high
grade long-term taxable bonds during various market conditions. The Lehman
Brothers Municipal Bond Index is an unmanaged index that generally represents
the performance of high grade intermediate and long-term municipal bonds during
various market conditions. Lipper calculates municipal bond fund averages based
on average maturity and credit quality. Morningstar rates mutual funds by
overall risk-adjusted performance, investment objectives, and assets. Lipper,
Morningstar, Wiesenberger and CDA are widely recognized mutual fund reporting
services whose performance calculations are based upon changes in net asset
value with all dividends reinvested and which do not include the effect of any
sales charges. The market prices and yields of taxable and tax-exempt bonds will
fluctuate. The Funds primarily invest in investment grade Municipal Obligations
in pursuing their objective of as high a level of current interest income which
is exempt from federal and state income tax as is consistent, in the view of the
Funds' management, with preservation of capital.
 
     The Funds may also compare their taxable equivalent total return
performance to the total return performance of taxable income funds such as
treasury securities funds, corporate bond funds (either investment grade or high
yield), or Ginnie Mae funds. These types of funds, because of the character of
their underlying securities, differ from municipal bond funds in several
respects. The susceptibility of the price of treasury bonds to credit risk is
far less than that of municipal bonds, but the price of treasury bonds tends to
be slightly more susceptible to change resulting from changes in market interest
rates. The susceptibility of the price of investment grade corporate bonds and
municipal bonds to market interest rate changes and general credit changes is
similar. High yield bonds are subject to a greater degree of price volatility
than municipal bonds resulting from changes in market interest rates and are
particularly susceptible to volatility from credit changes. Ginnie Mae bonds are
generally subject to less price volatility than municipal bonds from credit
concerns, due primarily to the fact that the timely payment of monthly
installments of principal and interest are backed by the full faith and credit
of the U.S. Government, but Ginnie Mae bonds of equivalent coupon and maturity
are generally more susceptible to price volatility resulting from market
interest rate changes. In addition, the volatility of Ginnie Mae bonds due to
changes in market interest rates may differ from municipal bonds of comparable
coupon and maturity because bonds of the sensitivity of Ginnie Mae prepayment
experience to change in interest rates.
 
                   ADDITIONAL INFORMATION ON THE PURCHASE AND
                           REDEMPTION OF FUND SHARES
 
     As described in the Prospectus, the Funds provide you with alternative ways
of purchasing Fund shares based upon your individual investment needs and
preferences.

     Each class of shares of a Fund represents an interest in the same portfolio
of investments. Each class of shares is identical in all respects except that
each class bears its own class expenses, including distribution and
administration expenses, and each class has exclusive voting rights with respect
to any distribution or service plan applicable to its shares. As a result of the
differences in the expenses borne by each class of shares, net income per share,
dividends per share and net asset value per share will vary among a Fund's
classes of shares.
 
     Shareholders of each class will share expenses proportionately for services
that are received equally by all shareholders. A particular class of shares will
bear only those expenses that are directly attributable to that class, where the
type or amount of services received by a class varies from one class to another.
For example, class-specific expenses generally will include distribution and
service fees.
 
     The minimum initial investment is $3,000 per fund share class, and may be
lower for accounts opened through fee-based programs for which the program
sponsor has established a single master account with the fund's transfer agent
and performs all sub-accounting services related to that account.
 
REDUCTION OR ELIMINATION OF UP-FRONT SALES CHARGE ON CLASS A SHARES
 
     Rights of Accumulation. You may qualify for a reduced sales charge on a
purchase of Class A Shares of any Fund if the amount of your purchase, when
added to the value that day of all of your prior purchases of shares of any Fund
or of another Nuveen Mutual Fund, or units of a Nuveen unit trust, on which an
up-front sales charge or ongoing distribution fee is imposed, or is normally
imposed, falls within the amounts stated in the Class A Sales Charges and
Commissions table in "How to Select a Purchase Option" in the Prospectus. You or
your financial adviser must notify Nuveen or the Fund's transfer agent of any
cumulative discount whenever you plan to purchase Class A Shares of a Fund that
you wish to qualify for a reduced sales charge.
 
     Letter of Intent. You may qualify for a reduced sales charge on a purchase
of Class A Shares of any Fund if you plan to purchase Class A Shares of Nuveen
Mutual Funds over the next 13 months and the total amount of your purchases
would, if purchased at one time, qualify you for one of the reduced sales
charges shown in the Class A Sales Charges and Commissions table in "How to
Select a Purchase Option" in the Prospectus. In order to take advantage of this
option, you must complete the applicable section of the Application Form or sign
and deliver either to an Authorized Dealer or to the Fund's transfer agent a
written Letter of Intent in a form acceptable to Nuveen. A Letter of Intent
states that you intend, but are not obligated, to purchase over the next 13
months a stated total amount of Class A shares that would qualify you for a
reduced sales charge shown above. You may count shares of a Nuveen Mutual Fund
that you already own on which you paid an up-front sales charge or an ongoing
distribution fee and any Class C Shares of a Nuveen Mutual Fund that you
purchase over the next 13 months towards completion of your investment program,
but you will receive a reduced sales charge only on new Class A Shares you
purchase with a sales charge over the 13 months. You cannot count towards
completion of your investment program Class A Shares that you purchase without a
sales charge through investment of distributions from a Nuveen Mutual Fund or a
Nuveen unit trust, or otherwise.
 
     By establishing a Letter of Intent, you agree that your first purchase of
Class A Shares of a Fund following execution of the Letter of Intent will be at
least 5% of the total amount of your intended purchases. You further agree that
shares representing 5% of the total amount of your intended purchases will be
held in escrow pending completion of these purchases. All dividends and capital
gains distributions on Class A Shares held in escrow will be credited to your
account. If total purchases, less redemptions, prior to the expiration of the 13
month period equal or exceed the amount specified in your Letter of Intent, the
Class A Shares held in escrow will be transferred to your account. If the total
purchases, less redemptions, exceed the amount specified in your Letter of
Intent and thereby qualify for a lower sales charge than the sales charge
specified in your Letter of Intent, you will receive this lower sales charge
retroactively, and the difference between it and the higher sales charge paid
will be used to purchase additional Class A Shares on your behalf. If the total
purchases, less redemptions, are less than the amount specified, you must pay
Nuveen an amount equal to the difference between the amounts paid for these
purchases and the amounts which would have been paid if the higher sales charge
had been applied. If you do not pay the additional amount within 20 days after
written request by Nuveen or your financial adviser, Nuveen will redeem an
appropriate number of your escrowed Class A Shares to meet the required payment.
By establishing a Letter of Intent, you irrevocably appoint Nuveen as attorney
to give instructions to redeem any or all of your escrowed shares, with full
power of substitution in the premises.
 
     You or your financial adviser must notify Nuveen or the Fund's transfer
agent whenever you make a purchase of Fund shares that you wish to be covered
under the Letter of Intent option.

any of the various unit trusts sponsored by Nuveen. There is no initial or
subsequent minimum investment requirement for such reinvestment purchases.
 
     Group Purchase Programs. If you are a member of a qualified group, you may
purchase Class A Shares of any Fund or of another Nuveen Mutual Fund at the
reduced sales charge applicable to the group's purchases taken as a whole. A
"qualified group" is one which has previously been in existence, has a purpose
other than investment, has ten or more participating members, has agreed to
include Fund sales publications in mailings to members and has agreed to comply
with certain administrative requirements relating to its group purchases.
 
     Under any group purchase program, the minimum monthly investment in Class A
Shares of any particular Fund or portfolio by each participant is $50, and the
minimum initial investment in Class A Shares of any particular Fund or portfolio
for each participant in the program combined is $3,000. No certificate will be
issued for any participant's account. All dividends and other distributions by a
Fund will be reinvested in additional Class A Shares of the same Fund. No
participant may utilize a systematic withdrawal program.
 
     To establish a group purchase program, both the group itself and each
participant must fill out special application materials, which the group
administrator may obtain from the group's financial adviser, by calling Nuveen
toll-free at (800) 621-7227.
 
     Reinvestment of Redemption Proceeds from Unaffiliated Funds. You may also
purchase Class A Shares at net asset value without a sales charge if the
purchase takes place through a broker-dealer and represents the reinvestment of
the proceeds of the redemption of shares of one or more registered investment
companies not affiliated with Nuveen. You must provide appropriate documentation
that the redemption occurred not more than one year prior to the reinvestment of
the proceeds in Class A Shares, and that you either paid an upfront sales charge
or were subject to a contingent deferred sales charge in respect of the
redemption of such shares of such other investment company.
 
     Class A Shares of a Fund may be purchased at net asset value without a
sales charge, and Class R Shares may be purchased, by the following categories
of investors:
 
     - officers, trustees and former trustees of the Nuveen and Flagship Funds;
 
     - bona fide, full-time and retired employees of Nuveen, any parent company
       of Nuveen, and subsidiaries thereof, or their immediate family members;
 
     - any person who, for at least 90 days, has been an officer, director or
       bona fide employee of any Authorized Dealer, or their immediate family
       members;
 
     - officers and directors of bank holding companies that make Fund shares
       available directly or through subsidiaries or bank affiliates or their
       immediate family members;
 
     - bank or broker-affiliated trust departments investing funds over which
       they exercise exclusive discretionary investment authority and that are
       held in a fiduciary, agency, advisory, custodial or similar capacity;
 
     - investors purchasing on a periodic fee, asset-based fee or no transaction
       fee basis through a broker-dealer sponsored mutual fund purchase program;
       and
 
     - clients of investment advisers, financial planners or other financial
       intermediaries that charge periodic or asset-based fees for their
       services.
 
     Holders of Class C Shares acquired on or before January 31, 1997 can
convert those shares to Class A Shares of the same fund at the shareholder's
affirmative request six years after date of purchase. Holders of Class C Shares
must submit their request to the transfer agent no later than the last business
day of the 71st month following the month in which they purchased their shares.
Holders of Class C Shares purchased after that date will not have the option to
convert those shares to Class A Shares.
 
     Any Class A Shares purchased pursuant to a special sales charge waiver must
be acquired for investment purposes and on the condition that they will not be
transferred or resold except through redemption by the Funds. You or your
financial adviser must notify Nuveen or the Fund's transfer agent whenever you
make a purchase of Class A Shares of any Fund that you wish to be covered under
these special sales charge waivers.
 
     Class A Shares of any Fund may be issued at net asset value without a sales
charge in connection with the acquisition by a Fund of another investment
company. All purchases under the special sales charge waivers will be subject to
minimum purchase requirements as established by the Funds.
 
                                      B-33
<PAGE>   188
 
     In determining the amount of your purchases of Class A Shares of any Fund
that may qualify for a reduced sales charge, the following purchases may be
combined: (1) all purchases by a trustee or other fiduciary for a single trust,
estate or fiduciary account; (2) all purchases by individuals and their
immediate family members (i.e., their spouses, parents, children, grandparents,
grandchildren parents-in-law, sons-and daughters-in-law, siblings, a sibling's
spouse, and a spouse's siblings); or (3) all purchases made through a group
purchase program as described above.
 
     Class R Share Purchase Eligibility. Class R Shares are available for
purchases of $1 million or more and for purchases using dividends and capital
gains distributions on Class R Shares. Class R Shares also are available for the
following categories of investors:
 
     - officers, trustees and former trustees of the Nuveen and Flagship Funds;
 
     - bona fide, full-time and retired employees of Nuveen, any parent company
       of Nuveen, and subsidiaries thereof, or their immediate family members;
 
     - any person who, for at least 90 days, has been an officer, director or
       bona fide employee of any Authorized Dealer, or their immediate family
       members;
 
     - officers and directors of bank holding companies that make Fund shares
       available directly or through subsidiaries or bank affiliates, or their
       immediate family members;
 
     - bank or broker-affiliated trust departments investing funds over which
       they exercise exclusive discretionary investment authority and that are
       held in a fiduciary, agency, advisory, custodial or similar capacity;
 
     - investors purchasing on a periodic fee, asset-based fee or no transaction
       fee basis through a broker-dealer sponsored mutual fund purchase program;
 
     - clients of investment advisers, financial planners or other financial
       intermediaries that charge periodic or asset-based fees for their
       services.
 
     In addition, purchasers of Nuveen unit investment trusts may reinvest their
distributions from such unit investment trusts in Class R Shares, if, before
September 6, 1994, such purchasers had elected to reinvest distributions in
Nuveen Fund shares (before June 13, 1995 for Nuveen Municipal Bond Fund shares).
Shareholders may exchange their Class R Shares of any Nuveen Fund into Class R
Shares of any other Nuveen Fund.
 
     The reduced sales charge programs may be modified or discontinued by the
Funds at any time upon prior written notice to shareholders of the Funds.
 
     For more information about the purchase of Class A Shares or reduced sales
charge programs, or to obtain the required application forms, call Nuveen
toll-free at (800) 621-7227.
 
REDUCTION OR ELIMINATION OF CONTINGENT DEFERRED SALES CHARGE
 
     Class A Shares are normally redeemed at net asset value, without any
Contingent Deferred Sales Charge ("CDSC"). However, in the case of Class A
Shares purchased at net asset value on or after July 1, 1996 because the
purchase amount exceeded $1 million, where the Authorized Dealer did not waive
the sales commission, a CDSC of 1% is imposed on any redemption within 18 months
of purchase. In the case of Class B Shares redeemed within six years of
purchase, a CDSC is imposed, beginning at 5% for redemptions within the first
year, declining to 4% for redemptions within years two and three, and declining
by 1% each year thereafter until disappearing after the sixth year. Class C
Shares are redeemed at net asset value, without any CDSC, except that a CDSC of
1% is imposed upon redemption of Class C Shares that are redeemed within 12
months of purchase.
 
     In determining whether a CDSC is payable, a Fund will first redeem shares
not subject to any charge, or that represent an increase in the value of a Fund
account due to capital appreciation, and then will redeem shares held for the
longest period, unless the shareholder specifies another order. No CDSC is
charged on shares purchased as a result of automatic reinvestment of dividends
or capital gains paid. In addition, no CDSC will be charged on exchanges of
shares into another Nuveen Mutual Fund or Nuveen money market fund. You may not
exchange Class B Shares for shares of a Nuveen money market fund. The holding
period is calculated on a monthly basis and begins the first day of the month in
which the order for investment is received. The CDSC is calculated based on the
lower of the redeemed shares' cost or net asset value at the time of the
redemption and is deducted from the redemption proceeds. Nuveen receives the
amount of any CDSC shareholders pay. If Class A or Class C shares subject to a
CDSC are exchanged for shares of a Nuveen money market fund, the CDSC would be
imposed on the subsequent redemption of those money market fund shares, and the
period during which the shareholder holds the
 
                                      B-34
<PAGE>   189
 
money market fund shares would be counted in determining the remaining duration
of the CDSC. The Fund may elect not to so count the period during which the
shareholder held the money market fund shares, in which event the amount of any
applicable CDSC would be reduced in accordance with applicable SEC rules by the
amount of any 12b-1 plan payments to which those money market funds shares may
be subject.
 
     The CDSC may be waived or reduced under the following six special
circumstances: 1) redemptions within one year following the death or disability,
as defined in Section 72(m)(7) of the Internal Revenue Code of 1986, as amended,
of a shareholder; 2) in whole or in part for redemptions of shares by
shareholders with accounts in excess of specified breakpoints that correspond to
the breakpoints under which the up-front sales charge on Class A Shares is
reduced pursuant to Rule 22d-1 under the Act; 3) redemptions of shares purchased
under circumstances or by a category of investors for which Class A Shares could
be purchased at net asset value without a sales charge; 4) in connection with
the exercise of a reinstatement privilege whereby the proceeds of a redemption
of a Fund's shares subject to a sales charge are reinvested in shares of certain
Funds within a specified number of days; 5) in connection with the exercise of a
Fund's right to redeem all shares in an account that does not maintain a certain
minimum balance or that the applicable board has determined may have material
adverse consequences to the shareholders of such Fund; and 6) redemptions made
pursuant to a Fund's automatic withdrawal plan, up to 12% annually of the
original investment amount. If a Fund waives or reduces the CDSC, such waiver or
reduction would be uniformly applied to all Fund shares in the particular
category. In waiving or reducing a CDSC, the Funds will comply with the
requirements of Rule 22d-1 of the Investment Company Act of 1940, as amended.
 
GENERAL MATTERS
 
     The Funds may encourage registered representatives and their firms to help
apportion their assets among bonds, stocks and cash, and may seek to participate
in programs that recommend a portion of their assets be invested in tax-free,
fixed income securities.
 
     In addition to the types of compensation to dealers to promote sales of
fund shares that are described in the prospectus, Nuveen may from time to time
make additional reallowances only to certain authorized dealers who sell or are
expected to sell certain minimum amounts of shares of the Nuveen mutual funds
during specified time periods.
 
     To help advisers and investors better understand and most efficiently use
the Fund to reach their investment goals, the Funds may advertise and create
specific investment programs and systems. For example, this may include
information on how to use the Funds to accumulate assets for future education
needs or periodic payments such as insurance premiums. The Funds may produce
software or additional sales literature to promote the advantages of using the
Funds to meet these and other specific investor needs.
 
     Exchanges of shares of a Fund for shares of a Nuveen money market fund may
be made on days when both funds calculate a net asset value and make shares
available for public purchase. Shares of the Nuveen money market funds may be
purchased on days on which the Federal Reserve Bank of Boston is normally open
for business. In addition to the holidays observed by the Fund, the Nuveen money
market funds observe and will not make fund shares available for purchase on the
following holidays: Martin Luther King's Birthday, Columbus Day and Veterans
Day.
 
     In addition, you may exchange Class R Shares of any Fund for Class A Shares
of the same Fund without a sales charge if the current net asset value of those
Class R Shares is at least $3,000 or you already own Class A Shares of that
Fund.
 
     Each Fund may suspend the right of redemption, or delay payment to
redeeming shareholders for more than seven days, when the New York Stock
Exchange is closed (not including customary weekend and holiday closings); when
trading in the markets a Fund normally uses is restricted, or the SEC determines
that an emergency exists so that trading of a Fund's portfolio securities or
determination of a Fund's net assets value is not reasonably practical; or the
SEC by order permits the suspension of the right of redemption or the delay in
payment to redeeming shareholders for more than seven days.
 
     Shares will be registered in the name of the investor or the investor's
financial adviser. A change in registration or transfer of shares held in the
name of a financial adviser may only be made by an order in good form from the
financial adviser acting on the investor's behalf. Share certificates will only
be issued upon written request to the Funds' transfer agent. No share
certificates will be issued for fractional shares.
 
     For more information on the procedure for purchasing shares of a Fund and
on the special purchase programs available thereunder, see "How to Buy Fund
Shares" in the Prospectus.

     Nuveen serves as the principal underwriter of the shares of the Funds
pursuant to a "best efforts" arrangement as provided by a distribution agreement
with the Nuveen Flagship Municipal Trust, dated February 1, 1997 ("Distribution
Agreement"). Pursuant to the Distribution Agreement, the Trust appointed Nuveen
to be its agent for the distribution of the Funds' shares on a continuous
offering basis. Nuveen sells shares to or through brokers, dealers, banks or
other qualified financial intermediaries (collectively referred to as
"Dealers"), or others, in a manner consistent with the then effective
registration statement of the Trust. Pursuant to the Distribution Agreement,
Nuveen, at its own expense, finances certain activities incident to the sale and
distribution of the Funds' shares, including printing and distributing of
prospectuses and statements of additional information to other than existing
shareholders, the printing and distributing of sales literature, advertising and
payment of compensation and giving of concessions to Dealers. Nuveen receives
for its services the excess, if any, of the sales price of the Funds' shares
less the net asset value of those shares, and reallows a majority or all of such
amounts to the Dealers who sold the shares; Nuveen may act as such a Dealer.
Nuveen also receives compensation pursuant to a distribution plan adopted by the
Trust pursuant to Rule 12b-1 and described herein under "Distribution and
Service Plan." Nuveen receives any CDSCs imposed on redemptions of Shares.
 
     The aggregate amounts of underwriting commissions with respect to the sale
of Fund shares and the amount thereof retained by Nuveen (or by Flagship
Financial, Inc., which Nuveen acquired on January 1, 1997), were as follows (all
figures are to the nearest thousand):

                         DISTRIBUTION AND SERVICE PLAN
 
     The Funds have adopted a plan (the "Plan") pursuant to Rule 12b-1 under the
Investment Company Act of 1940, which provides that Class B Shares and Class C
Shares will be subject to an annual distribution fee, and that Class A Shares,
Class B Shares and Class C Shares will be subject to an annual service fee.
Class R Shares will not be subject to either distribution or service fees.
 
     The distribution fee applicable to Class B and Class C Shares under each
Fund's Plan will be payable to reimburse Nuveen for services and expenses
incurred in connection with the distribution of Class B and Class C Shares,
respectively. These expenses include payments to Authorized Dealers, including
Nuveen, who are brokers of record with respect to the Class B and Class C
Shares, as well as, without limitation, expenses of printing and distributing
prospectuses to persons other than shareholders of the Fund, expenses of
preparing, printing and distributing advertising and sales literature and
reports to shareholders used in connection with the sale of Class B and Class C
Shares, certain other expenses associated with the distribution of Class B and
Class C Shares, and any distribution-related expenses that may be authorized
from time to time by the Board of Trustees.
 
     The service fee applicable to Class A Shares, Class B Shares and Class C
Shares under each Fund's Plan will be payable to Authorized Dealers in
connection with the provision of ongoing account services to shareholders. These
services may include establishing and maintaining shareholder accounts,
answering shareholder inquiries and providing other personal services to
shareholders.

     Each Fund may spend up to .20 of 1% per year of the average daily net
assets of Class A Shares as a service fee under the Plan applicable to Class A
Shares. Each Fund may spend up to .75 of 1% per year of the average daily net
assets of Class B Shares as a distribution fee and up to .20 of 1% per year of
the average daily net assets of Class B Shares as a service fee under the Plan
applicable to Class B Shares. Each Fund may spend up to .55 of 1% per year of
the average daily net assets of Class C Shares as a distribution fee and up to
 .20 of 1% per year of the average daily net assets of Class C Shares as a
service fee under the Plan applicable to Class C Shares.
 
     For the fiscal years ended April 30, 1997, 100% of service fees and
distribution fees were paid out as compensation to authorized dealers. Prior to
February 1, 1997, the service fee for the Nuveen Municipal Bond Fund and the
Nuveen Insured Municipal Bond Fund was .25% for both Class A and C Shares and
the distribution fee was .75% for Class C Shares. For the Nuveen Flagship
AllAmerican Municipal Bond Fund, the Nuveen Flagship Intermediate Municipal Bond
Fund and the Nuveen Flagship Limited Term Municipal Bond Fund, the service fee
was .20% for all Class C Shares and the distribution fee was .40% for Class A
Shares and .75% for Class C Shares (.50% for the Limited Term Fund). Thereafter,
the service fee for Class A, Class B, and Class C Shares was .20% and the
distribution fee was .75% for Class B Shares and .55% for Class C Shares (.35%
for the Limited Term Fund).

     Under each Fund's Plan, the Fund will report quarterly to the Board of
Trustees for its review all amounts expended per class of shares under the Plan.
The Plan may be terminated at any time with respect to any class of shares,
without the payment of any penalty, by a vote of a majority of the trustees who
are not "interested persons" and who have no direct or indirect financial
interest in the Plan or by vote of a majority of the outstanding voting
securities of such class. The Plan may be renewed from year to year if approved
by a vote of the Board of Trustees and a vote of the non-interested trustees who
have no direct or indirect financial interest in the Plan cast in person at a
meeting called for the purpose of voting on the Plan. The Plan may be continued
only if the trustees who vote to approve such continuance conclude, in the
exercise of reasonable business judgment and in light of their fiduciary duties
under applicable law, that there is a reasonable likelihood that the Plan will
benefit the Fund and its shareholders. The Plan may not be amended to increase
materially the cost which a class of shares may bear under the Plan without the
approval of the shareholders of the affected class, and any other material
amendments of the Plan must be approved by the non-interested trustees by a vote
cast in person at a meeting called for the purpose of considering such

the noninterested trustees of the Trust will be committed to the discretion of
the non-interested trustees then in office.

                                                                      APPENDIX A
 
                             RATINGS OF INVESTMENTS
 
     The four highest ratings of Moody's for Municipal Obligations are Aaa, Aa,
A and Baa. Municipal Obligations rated Aaa are judged to be of the "best
quality." The rating of Aa is assigned to Municipal Obligations which are of
"high quality by all standards," but as to which margins of protection or other
elements make long-term risks appear somewhat greater than in Aaa rated
Municipal Obligations. The Aaa and Aa rated Municipal Obligations comprise what
are generally known as "high grade bonds." Municipal Obligations that are rated
A by Moody's possess many favorable investment attributes and are considered
upper medium grade obligations. Factors giving security to principal and
interest of A rated Municipal Obligations are considered adequate, but elements
may be present, which suggest a susceptibility to impairment sometime in the
future. Municipal Obligations rated Baa by Moody's are considered medium grade
obligations (i.e., they are neither highly protected nor poorly secured). Such
bonds lack outstanding investment characteristics and in fact have speculative
characteristics as well. Moody's bond rating symbols may contain numerical
modifiers of a generic rating classification. The modifier 1 indicates that the
bond ranks at the high end of its category; the modifier 2 indicates a mid-range
ranking; and the modifier 3 indicates that the issue ranks in the lower end of
its general rating category.
 
     The four highest ratings of S&P for Municipal Obligations are AAA, AA, A
and BBB. Municipal Obligations rated AAA have a strong capacity to pay principal
and interest. The rating of AA indicates that capacity to pay principal and
interest is very strong and such bonds differ from AAA issues only in small
degree. The category of A describes bonds which have a strong capacity to pay
principal and interest, although such bonds are somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions. The BBB
rating is the lowest "investment grade" security rating by S&P. Municipal
Obligations rated BBB are regarded as having an adequate capacity to pay
principal and interest. Whereas such bonds normally exhibit adequate protection
parameters, adverse economic conditions are more likely to lead to a weakened
capacity to pay principal and interest for bonds in this category than for bonds
in the A category.
 
     The four highest ratings of Fitch for Municipal Obligations are AAA, AA, A
and BBB. Municipal Obligations rated AAA are considered to be investment grade
and of the highest credit quality. The obligor has an exceptionally strong
ability to pay interest and repay principal, which is unlikely to be affected by
reasonably foreseeable events. Municipal Obligations rated AA are considered to
be investment grade and of very high quality. The obligor's ability to pay
interest and repay principal is very strong, although not quite as strong as
bonds rated "AAA." Because Municipal Obligations rated in the "AAA" and "AA"
categories are not significantly vulnerable to foreseeable future developments,
short-term debt of these issuers is generally rated "F-1+." Municipal
Obligations rated A are considered to be investment grade and of high credit
quality. The obligor's ability to pay interest and repay principal is considered
to be strong, but may be more vulnerable to adverse changes in economic
conditions and circumstances than bonds with higher ratings. Municipal
Obligations rated BBB are considered to be investment grade and of satisfactory
credit quality. The obligor's ability to pay interest and repay principal is
considered to be adequate. Adverse changes in economic conditions and
circumstances, however, are more likely to have adverse impact on these bonds,
and therefore impair timely payment. The likelihood that the ratings of these
bonds will fall below investment grade is higher than for bonds with higher
ratings.
 
     The "Other Corporate Obligations" category of temporary investments are
corporate (as opposed to municipal) debt obligations rated AAA by S&P or Aaa by
Moody's. Corporate debt obligations rated AAA by S&P have an extremely strong
capacity to pay principal and interest. The Moody's corporate debt rating of Aaa
is comparable to that set forth above for Municipal Obligations.
 
     Subsequent to its purchase by a Fund, an issue may cease to be rated or its
rating may be reduced below the minimum required for purchase by such Fund.
Neither event requires the elimination of such obligation from a Fund's
portfolio, but Nuveen Advisory will consider such an event in its determination
of whether the Fund should continue to hold such obligation.

                       DESCRIPTION OF HEDGING TECHNIQUES
 
     Set forth below is additional information regarding the various Funds'
defensive hedging techniques and use of repurchase agreements.
 
FUTURES AND INDEX TRANSACTIONS
 
     Financial Futures. A financial future is an agreement between two parties
to buy and sell a security for a set price on a future date. They have been
designed by boards of trade which have been designated "contracts markets" by
the Commodity Futures Trading Commission ("CFTC").
 
     The purchase of financial futures is for the purpose of hedging a Fund's
existing or anticipated holdings of long-term debt securities. When a Fund
purchases a financial future, it deposits in cash or securities an "initial
margin" of between 1% and 5% of the contract amount. Thereafter, the Fund's
account is either credited or debited on a daily basis in correlation with the
fluctuation in price of the underlying future or other requirements imposed by
the exchange in order to maintain an orderly market. The Fund must make
additional payments to cover debits to its account and has the right to withdraw
credits in excess of the liquidity, the Fund may close out its position at any
time prior to expiration of the financial future by taking an opposite position.
At closing a final determination of debits and credits is made, additional cash
is paid by or to the Fund to settle the final determination and the Fund
realizes a loss or gain depending on whether on a net basis it made or received
such payments.
 
     The sale of financial futures is for the purpose of hedging a Fund's
existing or anticipated holdings of long-term debt securities. For example, if a
Fund owns long-term bonds and interest rates were expected to increase, it might
sell financial futures. If interest rates did increase, the value of long-term
bonds in the Fund's portfolio would decline, but the value of the Fund's
financial futures would be expected to increase at approximately the same rate
thereby keeping the net asset value of the Fund from declining as much as it
otherwise would have.
 
     Among the risks associated with the use of financial futures by the Funds
as a hedging device, perhaps the most significant is the imperfect correlation
between movements in the price of the financial futures and movements in the
price of the debt securities which are the subject of the hedge.
 
     Thus, if the price of the financial future moves less or more than the
price of the securities which are the subject of the hedge, the hedge will not
be fully effective. To compensate for this imperfect correlation, the Fund may
enter into financial futures in a greater dollar amount than the dollar amount
of the securities being hedged if the historical volatility of the prices of
such securities has been greater than the historical volatility of the financial
futures. Conversely, the Fund may enter into fewer financial futures if the
historical volatility of the price of the securities being hedged is less than
the historical volatility of the financial futures.
 
     The market prices of financial futures may also be affected by factors
other than interest rates. One of these factors is the possibility that rapid
changes in the volume of closing transactions, whether due to volatile markets
or movements by speculators, would temporarily distort the normal relationship
between the markets in the financial future and the chosen debt securities. In
these circumstances as well as in periods of rapid and large price movements.
The Fund might find it difficult or impossible to close out a particular
transaction.
 
     Options on Financial Futures. The Funds may also purchase put or call
options on financial futures which are traded on a U.S. Exchange or board of
trade and enter into closing transactions with respect to such options to
terminate an existing position. Currently, options can be purchased with respect
to financial futures on U.S. Treasury Bonds on The Chicago Board of Trade. The
purchase of put options on financial futures is analogous to the purchase of put
options by a Fund on its portfolio securities to hedge against the risk of
rising interest rates. As with options on debt securities, the holder of an
option may terminate his position by selling an option of the same Fund. There
is no guarantee that such closing transactions can be effected.
 
INDEX CONTRACTS
 
     Index Futures. A tax-exempt bond index which assigns relative values to the
tax-exempt bonds included in the index is traded on the Chicago Board of Trade.
The index fluctuates with changes in the market values of all tax-exempt bonds
included rather than a single bond. An index future is a bilateral agreement
pursuant to which two parties agree to take or make delivery of an amount of
cash -- rather than any security -- equal to specified dollar amount times the
difference between the index value at the close of the last trading day of the
contract and the price at which the index future was originally written. Thus,
an index future is similar to traditional financial futures except that
settlement is made in cash.
                                      BB-1
<PAGE>   195
 
     Index Options. The Funds may also purchase put or call options on U.S.
Government or tax-exempt bond index futures and enter into closing transactions
with respect to such options to terminate an existing position. Options on index
futures are similar to options on debt instruments except that an option on an
index future gives the purchaser the right, in return for the premium paid, to
assume a position in an index contract rather than an underlying security at a
specified exercise price at any time during the period of the option. Upon
exercise of the option, the delivery of the futures position by the writer of
the option to the holder of the option will be accompanied by delivery of the
accumulated balance of the writer's futures margin account which represents the
amount by which the market price of the index futures contract, at exercise, is
less than the exercise price of the option on the index future.
 
     Bond index futures and options transactions would be subject to risks
similar to transactions in financial futures and options thereon as described
above. No series will enter into transactions in index or financial futures or
related options unless and until, in the Adviser's opinion, the market for such
instruments has developed sufficiently.
 
REPURCHASE AGREEMENTS
 
     A Fund may invest temporarily up to 5% of its assets in repurchase
agreements, which are agreements pursuant to which securities are acquired by
the Fund from a third party with the understanding that they will be repurchased
by the seller at a fixed price on an agreed date. These agreements may be made
with respect to any of the portfolio securities in which the Fund is authorized
to invest. Repurchase agreements may be characterized as loans secured by the
underlying securities. The Fund may enter into repurchase agreements with (i)
member banks of the Federal Reserve System having total assets in excess of $500
million and (ii) securities dealers, provided that such banks or dealers meet
the creditworthiness standards established by the Fund's Board of Trustees
("Qualified Institutions"). The Adviser will monitor the continued
creditworthiness of Qualified Institutions, subject to the oversight of the
Fund's board of trustees.
 
     The use of repurchase agreements involves certain risks. For example, if
the seller of securities under a repurchase agreement defaults on its obligation
to repurchase the underlying securities, as a result of its bankruptcy or
otherwise, the Fund will seek to dispose of such securities, which action could
involve costs or delays. If the seller becomes insolvent and subject to
liquidation or reorganization under applicable bankruptcy or other laws, the
Fund's ability to dispose of the underlying securities may be restricted.
Finally, it is possible that the Fund may not be able to substantiate its
interest in the underlying securities. To minimize this risk, the securities
underlying the repurchase agreement will be held by the custodian at all times
in an amount at least equal to the repurchase price, including accrued interest.
If the seller fails to repurchase the securities, the Fund may suffer a loss to
the extent proceeds from the sale of the underlying securities are less than the
repurchase price.
 
     The resale price reflects the purchase price plus an agreed upon market
rate of interest which is unrelated to the coupon rate or date of maturity of
the purchased security. The collateral is marked to market daily. Such
agreements permit the Fund to keep all its assets earning interest while
retaining "overnight" flexibility in pursuit of investments of a longer-term
nature.

                  INVESTMENT POLICIES AND INVESTMENT PORTFOLIO
 
INVESTMENT POLICIES
 
     The investment objective and certain fundamental investment policies of
each Fund are described in the Prospectus. Each of the Funds, as a fundamental
policy, may not, without the approval of the holders of a majority of the shares
of that Fund:
 
          (1) Invest in securities other than Municipal Obligations and
     short-term securities, as described in the Prospectus. Municipal
     Obligations are municipal bonds that pay interest that is exempt from
     regular federal, state and, in some cases, local income taxes.
 
          (2) Invest more than 5% of its total assets in securities of any one
     issuer, except this limitation shall not apply to securities of the United
     States Government, and to the investment of 25% of such Fund's assets. This
     limitation shall apply only to the Georgia Municipal Bond Fund, the
     Louisiana Municipal Bond Fund, the North Carolina Municipal Bond Fund, and
     the Tennessee Municipal Bond Fund.
 
          (3) Borrow money, except from banks for temporary or emergency
     purposes and not for investment purposes and then only in an amount not
     exceeding (a) 10% of the value of its total assets at the time of borrowing
     or (b) one-third of the value of the Fund's total assets including the
     amount borrowed, in order to meet redemption requests which might otherwise
     require the untimely disposition of securities. While any such borrowings
     exceed 5% of such Fund's total assets, no additional purchases of
     investment securities will be made by such Fund. If due to market
     fluctuations or other reasons, the value of the Fund's assets falls below
     300% of its borrowings, the Fund will 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.
 
          (4) Pledge, mortgage or hypothecate its assets, except that, to secure
     borrowings permitted by subparagraph (2) above, it may pledge securities
     having a market value at the time of pledge not exceeding 10% of the value
     of the Fund's total assets.
 
          (5) Issue senior securities as defined in the Investment Company Act
     of 1940, except to the extent such issuance might be involved with respect
     to borrowings described under item (3) above or with respect to
     transactions involving futures contracts or the writing of options within
     the limits described in the Prospectus and this Statement of Additional
     Information.
 
          (6) Underwrite any issue of securities, except to the extent that the
     purchase or sale of Municipal Obligations in accordance with its investment
     objective, policies and limitations, may be deemed to be an underwriting.
 
          (7) Purchase or sell real estate, but this shall not prevent any Fund
     from investing in Municipal Obligations secured by real estate or interests
     therein or foreclosing upon and selling such security.
 
          (8) Purchase or sell commodities or commodities contracts or oil, gas
     or other mineral exploration or development programs, except for
     transactions involving futures contracts within the limits described in the
     Prospectus and this Statement of Additional Information.
 
          (9) Make loans, other than by entering into repurchase agreements and
     through the purchase of Municipal Obligations or temporary investments in
     accordance with its investment objective, policies and limitations.
 
          (10) Make short sales of securities or purchase any securities on
     margin, except for such short-term credits as are necessary for the
     clearance of transactions.
 
          (11) Write or purchase put or call options, except to the extent that
     the purchase of a stand-by commitment may be considered the purchase of a
     put, and except for transactions involving options within the limits
     described in the Prospectus and this Statement of Additional Information.
 
          (12) Invest more than 25% of its total assets in securities of issuers
     in any one industry; provided, however, that such limitations shall not be
     applicable to Municipal Obligations issued by governments or political
     subdivisions of governments, and obligations issued or guaranteed by the
     U.S. Government, its agencies or instrumentalities.
 
          (13) Purchase or retain the securities of any issuer other than the
     securities of the Fund if, to the Fund's knowledge, those trustees of the
     Trust, or those officers and directors of Nuveen Advisory Corp. ("Nuveen
 
                                       C-2
<PAGE>   198
 
     Advisory"), who individually own beneficially more than 1/2 of 1% of the
     outstanding securities of such issuer, together own beneficially more than
     5% of such outstanding securities.
 
     In addition, each Fund, as a non-fundamental policy, may not invest more
than 15% of its net assets in "illiquid" securities, including repurchase
agreements maturing in more than seven days.
 
     For the purpose of applying the limitations set forth in paragraph (2)
above, an issuer shall be deemed the sole issuer of a security when its assets
and revenues are separate from other governmental entities and its securities
are backed only by its assets and revenues. Similarly, in the case of a
non-governmental user, such as an industrial corporation or a privately owned or
operated hospital, if the security is backed only by the assets and revenues of
the non-governmental user, then such non-governmental user would be deemed to be
the sole issuer. Where a security is also backed by the enforceable obligation
of a superior or unrelated governmental entity or other entity (other than a
bond insurer), it shall also be included in the computation of securities owned
that are issued by such governmental or other entity.
 
     Where a security is guaranteed by a governmental entity or some other
facility, such as a bank guarantee or letter of credit, such a guarantee or
letter of credit would be considered a separate security and would be treated as
an issue of such government, other entity or bank. Where a security is insured
by bond insurance, it shall not be considered a security issued or guaranteed by
the insurer; instead the issuer of such security will be determined in
accordance with the principles set forth above. The foregoing restrictions do
not limit the percentage of the Fund's assets that may be invested in securities
insured by any single insurer.
 
     The foregoing restrictions and limitations, as well as a Fund's policies as
to ratings of portfolio investments, will apply only at the time of purchase of
securities, and the percentage limitations will not be considered violated
unless an excess or deficiency occurs or exists immediately after and as a
result of an acquisition of securities, unless otherwise indicated.
 
     The foregoing fundamental investment policies, together with the investment
objective of each Fund, cannot be changed without approval by holders of a
"majority of the Fund's outstanding voting shares." As defined in the Investment
Company Act of 1940, this means the vote of (i) 67% or more of the Fund's shares
present at a meeting, if the holders of more than 50% of the Fund's shares are
present or represented by proxy, or (ii) more than 50% of the Fund's shares,
whichever is less.
 
     The Nuveen Flagship Multistate Trust III (the "Trust") is an open-end
management series investment company organized as a Massachusetts business trust
on July 1, 1996. Each of the Funds is an open-end management investment company
organized as a series of the Nuveen Flagship Multistate Trust III. The Trust is
an open-end management series company under SEC Rule 18f-2. Each Fund is a
separate series issuing its own shares. The Trust currently has six series: the
Nuveen Flagship Alabama Municipal Bond Fund (formerly the Flagship Alabama
Double Tax Exempt Fund, a series of the Flagship Tax Exempt Funds Trust); the
Nuveen Flagship Georgia Municipal Bond Fund (formerly the Flagship Georgia
Double Tax Exempt Fund, a series of the Flagship Tax Exempt Funds Trust); the
Nuveen Flagship Louisiana Municipal Bond Fund (formerly the Flagship Louisiana
Double Tax Exempt Fund, a series of the Flagship Tax Exempt Funds Trust); the
Nuveen Flagship North Carolina Municipal Bond Fund (formerly the Flagship North
Carolina Tax Exempt Fund, a series of the Flagship Tax Exempt Funds Trust); the
Nuveen Flagship South Carolina Municipal Bond Fund (formerly the Flagship South
Carolina Double Tax Exempt Fund, a series of the Flagship Tax Exempt Funds
Trust); and the Nuveen Flagship Tennessee Municipal Bond Fund (formerly the
Flagship Tennessee Double Tax Exempt Fund, a series of the Flagship Tax Exempt
Funds Trust). Certain matters under the Investment Company Act of 1940 which
must be submitted to a vote of the holders of the outstanding voting securities
of a series company shall not be deemed to have been effectively acted upon
unless approved by the holders of a majority of the outstanding voting
securities of each Fund affected by such matter.
 
     The Trust is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders of a trust may, under
certain circumstances, be held personally liable as partners for its
obligations. However, the Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Trust and requires that
notice of this disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Trust or the Trustees. The Declaration of Trust
further provides for indemnification out of the assets and property of the Trust
for all loss and expense of any shareholder personally liable for the
obligations of the Trust. Thus, the risk of a shareholder incurring financial
loss on account of shareholder liability is limited to circumstances in which
both inadequate insurance existed and the Trust itself were unable to meet its
obligations. The Trust believes the likelihood of these circumstances is remote.

PORTFOLIO SECURITIES
 
     As described in the Prospectus, each of the Funds invests substantially all
of its assets (at least 80%) in a portfolio of Municipal Obligations free from
regular federal, state and, in some cases, local income tax in each Fund's
respective state, which generally will be Municipal Obligations issued within
the Fund's respective state. In general, Municipal Obligations include debt
obligations issued by states, cities and local authorities to obtain funds for
various public purposes, including construction of a wide range of public
facilities such as airports, bridges, highways, hospitals, housing, mass
transportation, schools, streets and water and sewer works. Industrial
development bonds and pollution control bonds that are issued by or on behalf of
public authorities to finance various privately-rated facilities are included
within the term Municipal Obligations if the interest paid thereon is exempt
from federal income tax.
 
     The investment assets of each Fund will consist of (1) Municipal
Obligations which are rated at the time of purchase within the four highest
grades (Baa or BBB or better) by Moody's Investors Service, Inc. ("Moody's"), by
Standard and Poor's Corporation ("S&P") or by Fitch Investors Service, Inc.
("Fitch"), (2) unrated Municipal Obligations which, in the opinion of Nuveen
Advisory, have credit characteristics equivalent to bonds rated within the four
highest grades by Moody's, S&P or Fitch, except that the Fund may not invest
more than 20% of its net assets in unrated bonds and (3) temporary investments
as described below, the income from which may be subject to state income tax or
to both federal and state income taxes. See Appendix A for more information
about ratings by Moody's, S&P, and Fitch.
 
     As described in the Prospectus, each Fund may invest in Municipal
Obligations that constitute participations in a lease obligation or installment
purchase contract obligation (hereafter collectively called "lease obligations")
of a municipal authority or entity. Although lease obligations do not constitute
general obligations of the municipality for which the municipality's taxing
power is pledged, a lease obligation is ordinarily backed by the municipality's
covenant to budget for, appropriate and make the payments due under the lease
obligation.
 
     However, certain lease obligations contain "non-appropriation" clauses
which provide that the municipality has no obligation to make lease or
installment purchase payments in future years unless money is appropriated for
such purpose on a yearly basis. Although nonappropriation lease obligations are
secured by the leased property, disposition of the property in the event of
foreclosure might prove difficult. A Fund will seek to minimize the special
risks associated with such securities by only investing in those
nonappropriation leases where Nuveen Advisory has determined that the issuer has
a strong incentive to continue making appropriations and timely payment until
the security's maturity. Some lease obligations may be illiquid under certain
circumstances. Lease obligations normally provide a premium interest rate which
along with regular amortization of the principal may make them attractive for a
portion of the assets of the Funds.
 
     Obligations of issuers of Municipal Obligations are subject to the
provisions of bankruptcy, insolvency and other laws affecting the rights and
remedies of creditors. In addition, the obligations of such issuers may become
subject to the laws enacted in the future by Congress, state legislatures or
referenda extending the time for payment of principal and/or interest, or
imposing other constraints upon enforcement of such obligations or upon
municipalities to levy taxes. There is also the possibility that, as a result of
legislation or other conditions, the power or ability of any issuer to pay, when
due, the principal of and interest on its Municipal Obligations may be
materially affected.
 
PORTFOLIO TRADING AND TURNOVER
 
     The Funds will make changes in their investment portfolio from time to time
in order to take advantage of opportunities in the municipal market and to limit
exposure to market risk. The Funds may also engage to a limited extent in
short-term trading consistent with their investment objective. Securities may be
sold in anticipation of market decline or purchased in anticipation of market
rise and later sold. In addition, a security may be sold and another of
comparable quality purchased at approximately the same time to take advantage of
what Nuveen Advisory believes to be a temporary disparity in the normal yield
relationship between the two securities. Each Fund may make changes in its
investment portfolio in order to limit its exposure to changing market
conditions. Changes in a Fund's investments are known as "portfolio turnover."
While it is impossible to predict future portfolio turnover rates, the annual
portfolio turnover rate for each of the Funds is generally not expected to
exceed 75%. However, each Fund reserves the right to make changes in its
investments whenever it deems such action advisable and, therefore, a Fund's
annual portfolio turnover rate may exceed 75% in particular years depending upon
market conditions.

WHEN-ISSUED SECURITIES
 
     Each Fund may purchase and sell Municipal Obligations on a when-issued or
delayed delivery basis. When-issued and delayed delivery transactions arise when
securities are purchased or sold with payment and delivery beyond the regular
settlement date. (When-issued transactions normally settle within 15-45 days.)
On such transactions the payment obligation and the interest rate are fixed at
the time the buyer enters into the commitment. The commitment to purchase
securities on a when-issued or delayed delivery basis may involve an element of
risk because the value of the securities is subject to market fluctuation, no
interest accrues to the purchaser prior to settlement of the transaction, and at
the time of delivery the market value may be less than cost. At the time a Fund
makes the commitment to purchase a Municipal Obligation on a when-issued or
delayed delivery basis, it will record the transaction and reflect the amount
due and the value of the security in determining its net asset value. Likewise,
at the time a Fund makes the commitment to sell a Municipal Obligation on a
delayed delivery basis, it will record the transaction and include the proceeds
to be received in determining its net asset value; accordingly, any fluctuations
in the value of the Municipal Obligation sold pursuant to a delayed delivery
commitment are ignored in calculating net asset value so long as the commitment
remains in effect. The Funds will maintain designated readily marketable assets
at least equal in value to commitments to purchase when-issued or delayed
delivery securities, such assets to be segregated by the Custodian specifically
for the settlement of such commitments. The Funds will only make commitments to
purchase Municipal Obligations on a when-issued or delayed delivery basis with
the intention of actually acquiring the securities, but the Funds reserve the
right to sell these securities before the settlement date if it is deemed
advisable. If a when-issued security is sold before delivery any gain or loss
would not be tax-exempt. The Funds commonly engage in when-issued transactions
in order to purchase or sell newly-issued Municipal Obligations, and may engage
in delayed delivery transactions in order to manage its operations more
effectively.
 
SPECIAL CONSIDERATIONS RELATING TO MUNICIPAL OBLIGATIONS OF DESIGNATED STATES
 
     As described in the Prospectus, except for investments in temporary
investments, each of the Funds will invest substantially all of its assets (at
least 80%) in municipal bonds that are exempt from federal and state tax in that
state ("Municipal Obligations"), generally Municipal Obligations issued in its
respective state. Each Fund is therefore more susceptible to political, economic
or regulatory factors adversely affecting issuers of Municipal Obligations in
its state. Brief summaries of these factors are contained in the Prospectus. Set
forth below is additional information that bears upon the risk of investing in
Municipal Obligations issued by public authorities in the states of currently
offered Funds. This information was obtained from official statements of issuers
located in the respective states as well as from other publicly available
official documents and statements. The Funds have not independently verified any
of the information contained in such statements and documents. The information
below is intended only as a general summary, and is not intended as a discussion
of any specific factor that may affect any particular obligation or issuer.
 
FACTORS PERTAINING TO ALABAMA
 
     The industrialization of Alabama's economy over the past two decades has
resulted in a manufacturing sector that represents just over a quarter of the
State's gross product and 21.7% of employment. Nine consecutive years of private
sector capital investment exceeding $2 billion annually has also left the
State's manufacturing facilities modernized and more competitive in the domestic
and world markets. In recent years, the importance of the service sector has
grown as regional concentrations such as the medical complex in Birmingham and
the high technology research center at Huntsville stimulate growth. The trade
and service sectors have provided 75% of job growth in recent years.
 
                                       C-5
<PAGE>   201
 
     The State's unemployment rate fell from 8.0% in 1994 to 4.5% in June 1997.
Alabama enjoyed a 25.9% increase in per capita income from 1990-94 outstripping
the 15.4% national growth during the same period. Per capita income growth also
significantly outpaced the national average during the period from 1980 to 1990.
However, personal income in the State remains below the national median at about
82% of the U.S. per capita average.
 
     Moody's gives Alabama general obligation bonds an Aa rating while S&P's
given them an AA rating.
 
FACTORS PERTAINING TO GEORGIA
 
     One of the nation's fastest growing states in terms of population, Georgia
has benefited from steady economic and employment growth as a result of the
State's stable and broad-based trade/service economy, low average cost of
living, and extensive transportation infrastructure. According to S&P, the 1996
Olympic games represented a sizable bubble on the State's economic trend line,
however, to date no significant drop-off from the State's pre-Olympic trend line
has occurred. This economic growth as well as the State's healthy financial
position were recognized in the State's recent rating upgrade from AA+ to AAA by
S&P.
 
     The State's unemployment level is low at 4.4% in June, 1997, down from 5.1%
in June of 1996. On a per capita basis, personal income is $22,709, equal to
about 94% of the national average and 104% of the region.
 
     Georgia's tight financial policies and conservative management have
resulted in a substantial operating surplus of $476 million and an unreserved
general fund balance of $621 million in fiscal 1996. The large surplus enabled
the State to increase reserves for debt service and expand the fiscal 1997
budget. As of July 31, 1997, Georgia's general obligation debt carries triple-A
ratings from S&P, Moody's, and Fitch.
 
FACTORS PERTAINING TO LOUISIANA
 
     Louisiana's economic base has experienced some improvement after the
recession of the 1980's. Population has increased approximately 3% since 1990
after ten years of zero growth. Per capita personal income has improved and was
$19,824 in 1996, but remains flat at about 80% of the national average. The
annual average unemployment rate for the State in 1996 was 6.7%, well above the
national average of 5.4%. Employment projections show increases of approximately
2% annually, with 66,000 additional jobs expected in the next two years. Single
family housing construction grew approximately 1.5% in 1996.
 
     The State possesses natural resources which have played a significant role
in driving the economy. Louisiana is the second largest petroleum refining
producer and the third largest producer of chemical products in the nation. In
the next year $700 million will be invested in three Direct Reduction Iron
facilities. Chemicals provide the largest employment in the manufacturing
industry. Tourism is the second largest industry in the State, adding $6.6
billion to the economy and generating $450 million in state and local taxes by
the end of 1995. Louisiana will continue to rely on the gaming industry, despite
a sector employment drop of about 4% in 1996 due to the consolidation and
downsizing of hotels and casinos.
 
     Financial operations have stabilized somewhat in recent years. The General
Fund ending balance increased 36% from fiscal year 1995 to fiscal year 1996. The
State's primary revenue sources are federal grants 27%, other taxes and revenues
16%, pension trust revenues 15%, and state sales and use taxes 13%. Federal
grants declined 9.3% due to Medicaid funding reductions. The State's primary
expenditures are for health and hospitals 32%, education 18%, colleges and
universities 14%. Debt service comprises approximately 4% of State expenditures.
Debt levels have moderated, declining approximately 42% since extremely high
levels in 1987. This decline is partly due to the recent retirement and
defeasement of bonds once issued by the Louisiana Recovery District to recover
deficits experienced in the 1980's.
 
     The State of Louisiana general obligation bond rating by S&P and Fitch are
A- and A, respectively. Moody's revised Louisiana's general obligation rating
from Baa1 to A3 in March of 1997.
 
FACTORS PERTAINING TO NORTH CAROLINA
 
     North Carolina's economy continues to grow and diversify. The State ranks
among the top ten states in terms of economic growth, as measured by employment,
population, and personal income growth. While manufacturing remains the State's
major employment sector, the services and retail trade sectors also supply a
significant percentage of employment. Growth in the high-technology sector has
helped diversify the State's economy and has also helped offset recent
employment losses in the textile, apparel, and tobacco industries.
 
                                       C-6
<PAGE>   202
 
     The State's unemployment rate was 3.6% in June 1997, below the national
average of 5.0% in June 1997 and down from the 4.3% rate for the State in June
1996. Per capita income grew from $13,716 in 1987 to $22,010 in 1996 but remains
below the national average of $24,231.
 
     The State has implemented sound financial policies and maintains low debt
levels. Its Constitution mandates that total expenditures not exceed receipts
for the same period plus any surplus available at the start of the fiscal year.
These conservative policies, combined with the State's economic recovery,
resulted in budget surpluses in each fiscal year 1992-1996. In February 1997,
Moody's, S&P, and Fitch confirmed their respective triple-A ratings for the
State.
 
FACTORS PERTAINING TO SOUTH CAROLINA
 
     Though still reliant on the textile industry, South Carolina's economy has
diversified into other areas such as trade, services, and durable goods
manufacturing. While not a wealthy state, employment growth has outpaced the
national growth rate. Steady economic gains are expected to continue as local
companies' expansion plans should contribute to future growth. The strength of
the job market, combined with low housing costs and the State's attractive
climate are expected to continue to attract new residents.
 
     The State's June 1997 unemployment rate (5.1%) stands slightly above the
5.0% national level. On a per capita basis, personal income was $19,755 in 1996,
equal to about 81% of the national average with personal income growth exceeding
the national rate.
 
     South Carolina's Constitution mandates a balanced budget and employs
several means to ensure its achievement. Each quarter the State Budget and
Control Board must monitor revenues and lower appropriations in the event the
State projects a deficit after the first or second quarters. The Constitution
also requires the government to set aside 3% of general fund revenues in a
General Reserve Fund and 2% in a Capital Reserve Fund as a hedge against any
year end deficit. During the fiscal year, the State must fund its operating
expenses with the Capital Reserve Fund moneys before resorting to any cuts in an
effort to meet projected deficits. At the end of the year, the legislature may
apply both funds to any deficit but any moneys taken from the General Reserve
must be replaced within 3 years. This sound fiscal policy allowed South Carolina
to end fiscal 1996 with a general fund balance of $285 million, $26 million over
fiscal 1995. As of July 31, 1997, South Carolina's general obligation debt
carries triple-A ratings from S&P, Moody's, and Fitch.
 
     The State recently revised its school bond intercept program. Under the new
legislation, the State may divert state aid funds directly to the paying agent
to pay debt service upon notification from a school district of an imminent
default. Previously, the State could divert funds only after a default had
occurred.
 
FACTORS PERTAINING TO TENNESSEE
 
     Tennessee's economy has diversified over the past several years.
Traditionally a manufacturing state, Tennessee has shifted toward services and
trade industries. Tennessee's average annual unemployment rate in 1996 was 5.2%,
compared to the nation's average rate of 5.4%. Tennessee's unemployment rate has
remained below the national average since 1989. The State's population has grown
steadily by approximately 1% annually. Personal income grew over 87% from 1983
to 1993 to reach $18,434 per capita. The per capita average increased again to
$21,764 in 1996.
 
     Tennessee's Constitution requires that a fiscal year's expenditures not
exceed that year's revenues and available reserves. Taxes represent the largest
source of governmental revenues, comprising 50.3% of revenues in 1996. Tax
collections increased 4.6% from 1995 due primarily to sales tax revenue growth.
Total governmental expenditures increased 2.2% from 1995, as education funding
was enhanced by 3.7%. Tennessee's Rainy Day Fund is stable at approximately $101
million. Debt levels are manageable. At 1996 fiscal year end, general obligation
debt in Tennessee totaled $634.7 million. Tennessee's solid fiscal budget
management is reflected in its general obligation ratings of Aaa/AA+/AAA by
Moody's, S&P and Fitch, respectively.
 
HEDGING AND OTHER DEFENSIVE ACTIONS
 
     Each Fund may periodically engage in hedging transactions. Hedging is a
term used for various methods of seeking to preserve portfolio capital value of
offsetting price changes in one investment through making another investment
whose price should tend to move in the opposite direction. It may be desirable
and possible in various market environments to partially hedge the portfolio
against fluctuations in market value due to interest rate fluctuations by
investment in financial futures and index futures as well as related put and
call options on such instruments. Both parties entering into an index or
financial futures contract are required to post an initial deposit of 1% to 5%
of the total contract price. Typically, option holders enter into offsetting
closing transactions to enable
                                       C-7
<PAGE>   203
 
settlement in cash rather than take delivery of the position in the future of
the underlying security. Each Fund will only sell covered futures contracts,
which means that the Fund segregates assets equal to the amount of the
obligations.
 
     These transactions present certain risks. In particular, the imperfect
correlation between price movements in the futures contract and price movements
in the securities being hedged creates the possibility that losses on the hedge
by a Fund may be greater than gains in the value of the securities in such
series, portfolio. In addition, futures and options markets may not be liquid in
all circumstances. As a result, in volatile markets, a Fund may not be able to
close out the transaction without incurring losses substantially greater than
the initial deposit. Finally, the potential daily deposit requirements in
futures contracts create an ongoing greater potential financial risk than do
options transactions, where the exposure is limited to the cost of the initial
premium. Losses due to hedging transactions will reduce yield. Net gains, if
any, from hedging and other portfolio transactions will be distributed as
taxable distributions to shareholders.
 
     No Fund will make any investment (whether an initial premium or deposit or
a subsequent deposit) other than as necessary to close a prior investment if,
immediately after such investment, the sum of the amount of its premiums and
deposits would exceed 5% of such series' net assets. Each series will invest in
these instruments only in markets believed by the investment adviser to be
active and sufficiently liquid. For further information regarding these
investment strategies and risks presented thereby, see Appendix B to this
Statement of Additional Information.
 
     Each Fund reserves the right for liquidity or defensive purposes (such as
thinness in the market for municipal securities or an expected substantial
decline in value of long-term obligations), to temporarily invest up to 20% of
its assets in obligations issued or guaranteed by the U.S. Government and its
agencies or instrumentalities, including up to 5% in adequately collateralized
repurchase agreements relating thereto. Interest on each instrument is taxable
for Federal income tax purposes and would reduce the amount of tax-free interest
payable to shareholders.
 
SHORT-TERM SECURITIES
 
     The Prospectus discusses briefly the ability of the Funds to invest a
portion of their assets in federally tax-exempt or taxable short-term securities
("temporary investments"). Temporary investments will not exceed 20% of a Fund's
assets except when made for defensive purposes. The Funds will invest only in
taxable temporary investments that are either U.S. Government securities or are
rated within the highest grade by Moody's, S&P, or Fitch and mature within one
year from the date of purchase or carry a variable or floating rate of interest.
See Appendix A for more information about ratings by Moody's, S&P, and Fitch.
 
     The Funds may invest in the following federally tax-exempt temporary
investments:
 
     Bond Anticipation Notes (BANs) are usually general obligations of state and
local governmental issuers which are sold to obtain interim financing for
projects that will eventually be funded through the sale of long-term debt
obligations or bonds. The ability of an issuer to meet its obligations on its
BANs is primarily dependent on the issuer's access to the long-term municipal
bond market and the likelihood that the proceeds of such bond sales will be used
to pay the principal and interest on the BANs.
 
     Tax Anticipation Notes (TANs) are issued by state and local governments to
finance the current operations of such governments. Repayment is generally to be
derived from specific future tax revenues. Tax anticipation notes are usually
general obligations of the issuer. A weakness in an issuer's capacity to raise
taxes due to, among other things, a decline in its tax base or a rise in
delinquencies, could adversely affect the issuer's ability to meet its
obligations on outstanding TANs.
 
     Revenue Anticipation Notes (RANs) are issued by governments or governmental
bodies with the expectation that future revenues from a designated source will
be used to repay the notes. In general, they also constitute general obligations
of the issuer. A decline in the receipt of projected revenues, such as
anticipated revenues from another level of government, could adversely affect an
issuer's ability to meet its obligations on outstanding RANs. In addition, the
possibility that the revenues would, when received, be used to meet other
obligations could affect the ability of the issuer to pay the principal and
interest on RANs.
 
     Construction Loan Notes are issued to provide construction financing for
specific projects. Frequently, these notes are redeemed with funds obtained from
the Federal Housing Administration.
 
     Bank Notes are notes issued by local government bodies and agencies as
those described above to commercial banks as evidence of borrowings. The
purposes for which the notes are issued are varied but they are frequently
 
                                       C-8
<PAGE>   204
 
issued to meet short-term working capital or capital-project needs. These notes
may have risks similar to the risks associated with TANs and RANs.
 
     Tax-Exempt Commercial Paper (Municipal Paper) represents very short-term
unsecured, negotiable promissory notes, issued by states, municipalities and
their agencies. Payment of principal and interest on issues of municipal paper
may be made from various sources, to the extent the funds are available
therefrom. Maturities of municipal paper generally will be shorter than the
maturities of TANs, BANs or RANs. There is a limited secondary market for issues
of municipal paper.
 
     Certain Municipal Obligations may carry variable or floating rates of
interest whereby the rate of interest is not fixed, but varies with changes in
specified market rates or indices, such as a bank prime rate or a tax-exempt
money market index.
 
     While these various types of notes as a group represent the major portion
of the tax-exempt note market, other types of notes are occasionally available
in the marketplace and the Fund may invest in such other types of notes to the
extent permitted under its investment objective, policies and limitations. Such
notes may be issued for different purposes and may be secured differently from
those mentioned above.
 
     The Funds may also invest in the following taxable temporary investments:
 
     U.S. Government Direct Obligations are issued by the United States Treasury
and include bills, notes and bonds.
 
     --  Treasury bills are issued with maturities of up to one year. They are
         issued in bearer form, are sold on a discount basis and are payable at
         par value at maturity.
 
     --  Treasury notes are longer-term interest bearing obligations with
         original maturities of one to seven years.
 
     --  Treasury bonds are longer-term interest-bearing obligations with
         original maturities from five to thirty years.
 
     U.S. Government Agencies Securities--Certain federal agencies have been
established as instrumentalities of the United States Government to supervise
and finance certain types of activities. These agencies include, but are not
limited to, the Bank for Cooperatives, Federal Land Banks, Federal Intermediate
Credit Banks, Federal Home Loan Banks, Federal National Mortgage Association,
Government National Mortgage Association, Export-Import Bank of the United
States, and Tennessee Valley Authority. Issues of these agencies, while not
direct obligations of the United States Government, are either backed by the
full faith and credit of the United States or are guaranteed by the Treasury or
supported by the issuing agencies' right to borrow from the Treasury. There can
be no assurance that the United States Government itself will pay interest and
principal on securities as to which it is not legally so obligated.
 
     Certificates of Deposit (CDs)--A certificate of deposit is a negotiable
interest bearing instrument with a specific maturity. CDs are issued by banks in
exchange for the deposit of funds and normally can be traded in the secondary
market, prior to maturity. The Fund will only invest in U.S. dollar denominated
CDs issued by U.S. banks with assets of $1 billion or more.
 
     Commercial Paper--Commercial paper is the term used to designate unsecured
short-term promissory notes issued by corporations. Maturities on these issues
vary from a few days to nine months. Commercial paper may be purchased from U.S.
corporations.
 
     Other Corporate Obligations--The Funds may purchase notes, bonds and
debentures issued by corporations if at the time of purchase there is less than
one year remaining until maturity or if they carry a variable or floating rate
of interest.
 
     Repurchase Agreements--A repurchase agreement is a contractual agreement
whereby the seller of securities (U.S. Government or Municipal Obligations)
agrees to repurchase the same security at a specified price on a future date
agreed upon by the parties. The agreed upon repurchase price determines the
yield during a Fund's holding period. Repurchase agreements are considered to be
loans collateralized by the underlying security that is the subject of the
repurchase contract. The Funds will only enter into repurchase agreements with
dealers, domestic banks or recognized financial institutions that in the opinion
of Nuveen Advisory present minimal credit risk. The risk to the Funds is limited
to the ability of the issuer to pay the agreed-upon repurchase price on the
delivery date; however, although the value of the underlying collateral at the
time the transaction is entered into always equals or exceeds the agreed-upon
repurchase price, if the value of the collateral declines there is a risk of
loss of both principal and interest. In the event of default, the collateral may
be sold but a Fund might incur a loss if the value of
 
                                       C-9
<PAGE>   205
 
the collateral declines, and might incur disposition costs or experience delays
in connection with liquidating the collateral. In addition, if bankruptcy
proceedings are commenced with respect to the seller of the security,
realization upon the collateral by a Fund may be delayed or limited. Nuveen
Advisory will monitor the value of collateral at the time the transaction is
entered into and at all times subsequent during the term of the repurchase
agreement in an effort to determine that the value always equals or exceeds the
agreed upon price. In the event the value of the collateral declined below the
repurchase price, Nuveen Advisory will demand additional collateral from the
issuer to increase the value of the collateral to at least that of the
repurchase price. Each of the Funds will not invest more than 10% of its assets
in repurchase agreements maturing in more than seven days.

                                   MANAGEMENT
 
     The management of the Trust, including general supervision of the duties
performed for the Funds under the Investment Management Agreement, is the
responsibility of its Board of Trustees. The Trust currently has eight trustees,
two of whom are "interested persons" (as the term "interested persons" is
defined in the Investment Company Act of 1940) and six of whom are
"disinterested persons." The names and business addresses of the trustees and
officers of the Trust and their principal occupations and other affiliations
during the past five years are set forth below, with those trustees who are
"interested persons" of the Trust indicated by an asterisk.

</TABLE>
 
     In addition to the management fee of Nuveen Advisory, each Fund pays all
other costs and expenses of its operations and a portion of the Trust's general
administrative expenses allocated in proportion to the net assets of each Fund.
 
     Nuveen Advisory is a wholly owned subsidiary of John Nuveen & Co.
Incorporated ("Nuveen"), the Funds' principal underwriter. In 1961, Nuveen began
sponsoring the Nuveen Tax-Exempt Unit Trust and since that time has issued more
than $36 billion in tax-exempt unit trusts, including over $12 billion in
tax-exempt insured unit trusts. In addition, Nuveen open-end and closed-end
funds held approximately $36 billion in tax-exempt securities under management
as of the date of this Statement. Over 1,000,000 individuals have invested to
date in Nuveen's tax-exempt funds and trusts. Founded in 1898, 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 in St. Paul,
Minnesota and is principally engaged in providing property-liability insurance
through subsidiaries. Effective January 1, 1997, The John Nuveen Company
acquired Flagship Resources Inc., and as part of that acquisition, Flagship
Financial, the adviser to the Flagship Funds, was merged with Nuveen Advisory.
 
     Nuveen Advisory's portfolio managers call upon the resources of Nuveen's
Research Department. The Nuveen Research Department reviews more than $100
billion in municipal bonds every year.
 
     The Funds, the other Nuveen funds, Nuveen Advisory, and other related
entities have adopted a code of ethics which essentially prohibits all Nuveen
fund management personnel, including Nuveen fund portfolio managers, from
engaging in personal investments which compete or interfere with, or attempt to
take advantage of, a Fund's anticipated or actual portfolio transactions, and is
designed to assure that the interests of Fund shareholders are placed before the
interests of Nuveen personnel in connection with personal investment
transactions.
 
                             PORTFOLIO TRANSACTIONS
 
     Nuveen Advisory, in effecting purchases and sales of portfolio securities
for the account of each Fund, will place orders in such manner as, in the
opinion of management, will offer the best price and market for the execution
                                      C-18
<PAGE>   214
 
of each transaction. Portfolio securities will normally be purchased directly
from an underwriter or in the over-the-counter market from the principal dealers
in such securities, unless it appears that a better price or execution may be
obtained elsewhere. Portfolio securities will not be purchased from Nuveen or
its affiliates except in compliance with the Investment Company Act of 1940.
 
     The Funds expect that all portfolio transactions will be effected on a
principal (as opposed to an agency) basis and, accordingly, do not expect to pay
any brokerage commissions. Purchases from underwriters will include a commission
or concession paid by the issuer to the underwriter, and purchases from dealers
will include the spread between the bid and asked price. Given the best price
and execution obtainable, it will be the practice of the Funds to select dealers
which, in addition, furnish research information (primarily credit analyses of
issuers and general economic reports) and statistical and other services to
Nuveen Advisory. It is not possible to place a dollar value on information and
statistical and other services received from dealers. Since it is only
supplementary to Nuveen Advisory's own research efforts, the receipt of research
information is not expected to reduce significantly Nuveen Advisory's expenses.
While Nuveen Advisory will be primarily responsible for the placement of the
business of the Funds, the policies and practices of Nuveen Advisory in this
regard must be consistent with the foregoing and will, at all times, be subject
to review by the Board of Trustees.
 
     Nuveen Advisory reserves the right to, and does, manage other investment
accounts and investment companies for other clients, which may have investment
objectives similar to the Funds. Subject to applicable laws and regulations,
Nuveen Advisory will attempt to allocate equitably portfolio transactions among
the Funds and the portfolios of its other clients purchasing or selling
securities whenever decisions are made to purchase or sell securities by a Fund
and one or more of such other clients simultaneously. In making such allocations
the main factors to be considered will be the respective investment objectives
of the Fund and such other clients, the relative size of portfolio holdings of
the same or comparable securities, the availability of cash for investment by
the Fund and such other clients, the size of investment commitments generally
held by the Fund and such other clients and opinions of the persons responsible
for recommending investments to the Fund and such other clients. While this
procedure could have a detrimental effect on the price or amount of the
securities available to a Fund from time to time, it is the opinion of the Board
of Trustees that the benefits available from Nuveen Advisory's organization will
outweigh any disadvantage that may arise from exposure to simultaneous
transactions.
 
     Under the Investment Company Act of 1940, the Funds may not purchase
portfolio securities from any underwriting syndicate of which Nuveen is a member
except under certain limited conditions set forth in Rule 10f-3. The Rule sets
forth requirements relating to, among other things, the terms of an issue of
Municipal Obligations purchased by a Fund, the amount of Municipal Obligations
which may be purchased in any one issue and the assets of a Fund which may be
invested in a particular issue. In addition, purchases of securities made
pursuant to the terms of the Rule must be approved at least quarterly by the
Board of Trustees, including a majority of the trustees who are not interested
persons of the Trust.
 
                                NET ASSET VALUE
 
     As stated in the Prospectus, the net asset value of the shares of the Funds
will be determined separately for each class of the Funds' shares by The Chase
Manhattan Bank, the Funds' custodian, as of the close of trading (normally 4:00
p.m. Eastern Time) on each day on which the Exchange is normally open for
trading. The Exchange is not open for trading on New Year's Day, Washington's
Birthday, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving
Day and Christmas Day. The net asset value per share of a class of shares of a
Fund will be computed by dividing the value of the Fund's assets attributable to
the class, less the liabilities attributable to the class, by the number of
shares of the class outstanding.
 
     In determining net asset value for the Funds, each Fund's custodian
utilizes the valuations of portfolio securities furnished by a pricing service
approved by the trustees. Securities for which quotations are not readily
available (which constitute a majority of the securities held by the Funds) are
valued at fair value as determined by the pricing service using methods which
include consideration of the following: yields or prices of municipal bonds of
comparable quality, type of issue, coupon, maturity and rating; indications as
to value from dealers; and general market conditions. The pricing service may
employ electronic data processing techniques and/or a matrix system to determine
valuations. The procedures of the pricing service and its valuations are
reviewed by the officers of the Trust under the general supervision of the Board
of Trustees.

                                  TAX MATTERS
 
FEDERAL INCOME TAX MATTERS
 
     The following discussion of federal income tax matters is based upon the
advice of Fried, Frank, Harris, Shriver & Jacobson, counsel to the Trust.
 
     Each Fund intends to qualify under Subchapter M of the Internal Revenue
Code of 1986, as amended (the "Code") for tax treatment as a regulated
investment company. In order to qualify as a regulated investment company, a
Fund must satisfy certain requirements relating to the source of its income,
diversification of its assets, and distributions of its income to shareholders.
First, a Fund must derive at least 90% of its annual gross income (including
tax-exempt interest) from dividends, interest, payments with respect to
securities loans, gains from the sale or other disposition of stock or
securities, foreign currencies or other income (including but not limited to
gains from options and futures) derived with respect to its business of
investing in such stock or securities (the "90% gross income test"). Second, for
taxable years beginning on or before August 5, 1997, a Fund must derive less
than 30% of its annual gross income from the sale or other disposition of any of
the following which was held for less than three months: (i) stock or securities
and (ii) certain options, futures, or forward contracts (the "short-short
test"). The short-short test will not be a requirement for qualification as a
regulated investment company for taxable years beginning after August 5, 1997.
Third, a Fund must diversify its holdings so that, at the close of each quarter
of its taxable year, (i) at least 50% of the value of its total assets is
comprised of cash, cash items, United States Government securities, securities
of other regulated investment companies and other securities limited in respect
of any one issuer to an amount not greater in value than 5% of the value of a
Fund's total assets and to not more than 10% of the outstanding voting
securities of such issuer, and (ii) not more than 25% of the value of the total
assets is invested in the securities of any one issuer (other than United States
Government securities and securities of other regulated investment companies) or
two or more issuers controlled by a Fund and engaged in the same, similar or
related trades or businesses.
 
     As a regulated investment company, a Fund will not be subject to federal
income tax in any taxable year for which it distributes at least 90% of the sum
of (i) its "investment company taxable income" (which includes dividends,
taxable interest, taxable original issue discount and market discount income,
income from securities lending, net short-term capital gain in excess of
long-term capital loss, and any other taxable income other than "net capital
gain" (as defined below) and is reduced by deductible expenses) and (ii) its net
tax-exempt interest (the excess of its gross tax-exempt interest income over
certain disallowed deductions). A Fund may retain for investment its net capital
gain (which consists of the excess of its net long-term capital gain over its
short-term capital loss). However, if a Fund retains any net capital gain or any
investment company taxable income, it will be subject to tax at regular
corporate rates on the amount retained. If a Fund retains any capital gain, such
Fund may designate the retained amount as undistributed capital gains in a
notice to its shareholders who, if subject to federal income tax on long-term
capital gains, (i) will be required to include in income for federal income tax
purposes, as long-term capital gain, their shares of such undistributed amount,
and (ii) will be entitled to credit their proportionate shares of the tax paid
by such Fund against their federal income tax liabilities if any, and to claim
refunds to the extent the credit exceeds such liabilities. For federal income
tax purposes, the tax basis of shares owned by a shareholder of the Fund will be
increased by an amount equal under current law to 65% of the amount of
undistributed capital gains included in the shareholder's gross income. Each
Fund intends to distribute at least annually to its shareholders all or
substantially all of its net tax-exempt interest and any investment company
taxable income and net capital gain.
 
     Treasury regulations permit a regulated investment company, in determining
its investment company taxable income and net capital gain, i.e., the excess of
net long-term capital gain over net short-term capital loss for any taxable
year, to elect (unless it has made a taxable year election for excise tax
purposes as discussed below) to treat all or part of any net capital loss, any
net long-term capital loss or any net foreign currency loss incurred after
October 31 as if they had been incurred in the succeeding year.
 
     Each Fund also intends to satisfy conditions (including requirements as to
the proportion of its assets invested in Municipal Obligations) that will enable
it to designate distributions from the interest income generated by investments
in Municipal Obligations, which is exempt from regular federal income tax when
received by such Fund, as exempt-interest dividends. Shareholders receiving
exempt-interest dividends will not be subject to regular federal income tax on
the amount of such dividends. Insurance proceeds received by a Fund under any
insurance policies in respect of scheduled interest payments on defaulted
Municipal Obligations will be excludable from federal gross income under Section
103(a) of the Code. In the case of non-appropriation by a political subdivision,
however, there can be no assurance that payments made by the insurer
representing interest on "non-appropriation"
 
                                      C-20
<PAGE>   216
 
lease obligations will be excludable from gross income for federal income tax
purposes. See "Investment Policies and Investment Portfolio; Portfolio
Securities."
 
     Distributions by a Fund of net interest received from certain taxable
temporary investments (such as certificates of deposit, commercial paper and
obligations of the U.S. Government, its agencies and instrumentalities) and net
short-term capital gains realized by a Fund, if any, will be taxable to
shareholders as ordinary income whether received in cash or additional shares.
If a Fund purchases a Municipal Obligation at a market discount, any gain
realized by the Fund upon sale or redemption of the Municipal Obligation will be
treated as taxable interest income to the extent such gain does not exceed the
market discount, and any gain realized in excess of the market discount will be
treated as capital gains. Any net long-term capital gains realized by a Fund and
distributed to shareholders in cash or additional shares, will be taxable to
shareholders as long-term capital gains regardless of the length of time
investors have owned shares of a Fund. Distributions by a Fund that do not
constitute ordinary income dividends, exempt-interest dividends, or capital gain
dividends will be treated as a return of capital to the extent of (and in
reduction of) the shareholder's tax basis in his or her shares. Any excess will
be treated as gain from the sale of his or her shares, as discussed below.
 
     If a Fund has both tax-exempt and taxable income, it will use the "average
annual" method for determining the designated percentage that is taxable income
and designate the use of such method within 60 days after the end of the Fund's
taxable year. Under this method, one designated percentage is applied uniformly
to all distributions made during the Fund's taxable year. The percentage of
income designated as tax-exempt for any particular distribution may be
substantially different from the percentage of the Fund's income that was
tax-exempt during the period covered by the distribution.
 
     If a Fund engages in hedging transactions involving financial futures and
options, these transactions will be subject to special tax rules, the effect of
which may be to accelerate income to a Fund, defer a Fund's losses, cause
adjustments in the holding periods of a Fund's securities, convert long-term
capital gains into short-term capital gains and convert short-term capital
losses into long-term capital losses. These rules could therefore affect the
amount, timing and character of distributions to shareholders.
 
     Because the taxable portion of a Fund's investment income consists
primarily of interest, none of its dividends, whether or not treated as
exempt-interest dividends, is expected to qualify under the Internal Revenue
Code for the dividends received deductions for corporations.
 
     Prior to purchasing shares in a Fund, the impact of dividends or
distributions which are expected to be or have been declared, but not paid,
should be carefully considered. Any dividend or distribution declared shortly
after a purchase of such shares prior to the record date will have the effect of
reducing the per share net asset value by the per share amount of the dividend
or distribution.
 
     Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in one of those months and paid during the following
January, will be treated as having been distributed by a Fund (and received by
the shareholders) on December 31.
 
     The redemption or exchange of the shares of a Fund normally will result in
capital gain or loss to the shareholders. Present law taxes both long- and
short-term capital gains of corporations at the rates applicable to ordinary
income. For non-corporate taxpayers, however, (i) gain on the sale of shares
held for more than 18 months will generally be taxed at a maximum marginal rate
of 20%, (ii) gain on the sale of shares held for more than one year but not more
than 18 months will generally be taxed at a maximum marginal rate of 28%, and
(iii) gain on the sale of shares held for not more than one year and other
ordinary income will generally be taxed at a maximum marginal rate of 39.6%.
Because of the limitations on itemized deductions and the deduction for personal
exemptions applicable to higher income taxpayers, the effective tax rate on net
income may be higher in certain circumstances.
 
     All or a portion of a sales charge paid in purchasing shares of a Fund
cannot be taken into account for purposes of determining gain or loss on the
redemption or exchange of such shares within 90 days after their purchase to the
extent shares of a Fund or another fund are subsequently acquired without
payment of a sales charge pursuant to the reinvestment or exchange privilege.
Any disregarded portion of such charge will result in an increase in the
shareholder's tax basis in the shares subsequently acquired. Moreover, losses
recognized by a shareholder on the redemption or exchange of shares of a Fund
held for six months or less are disallowed to the extent of any distribution of
exempt-interest dividends received with respect to such shares and, if not
disallowed, such losses are treated as long-term capital losses to the extent of
any distributions of long-term capital gains made with respect to such shares.
In addition, no loss will be allowed on the redemption or exchange of shares of
a Fund if the
                                      C-21
<PAGE>   217
 
shareholder purchases other shares of such Fund (whether through reinvestment of
distributions or otherwise) or the shareholder acquires or enters into a
contract or option to acquire securities that are substantially identical to
shares of a Fund within a period of 61 days beginning 30 days before and ending
30 days after such redemption or exchange. If disallowed, the loss will be
reflected in an adjustment to the basis of the shares acquired.
 
     It may not be advantageous from a tax perspective for shareholders to
redeem or exchange shares after tax-exempt income has accrued but before the
record date for the exempt-interest dividend representing the distribution of
such income. Because such accrued tax-exempt income is included in the net asset
value per share (which equals the redemption or exchange value), such a
redemption could result in treatment of the portion of the sales or redemption
proceeds equal to the accrued tax-exempt interest as taxable gain (to the extent
the redemption or exchange price exceeds the shareholder's tax basis in the
shares disposed of) rather than tax-exempt interest.
 
     In order to avoid a 4% federal excise tax, a Fund must distribute or be
deemed to have distributed by December 31 of each calendar year at least 98% of
its taxable ordinary income for such year, at least 98% of the excess of its
realized capital gains over its realized capital losses (generally computed on
the basis of the one-year period ending on October 31 of such year) and 100% of
any taxable ordinary income and the excess of realized capital gains over
realized capital losses for the prior year that was not distributed during such
year and on which such Fund paid no federal income tax. For purposes of the
excise tax, a regulated investment company may reduce its capital gain net
income (but not below its net capital gain) by the amount of any net ordinary
loss for the calendar year. The Funds intend to make timely distributions in
compliance with these requirements and consequently it is anticipated that they
generally will not be required to pay the excise tax.
 
     If in any year a Fund should fail to qualify under Subchapter M for tax
treatment as a regulated investment company, the Fund would incur a regular
corporate federal income tax upon its income for that year (other than interest
income from Municipal Obligations), and distributions to its shareholders would
be taxable to shareholders as ordinary dividend income for federal income tax
purposes to the extent of the Fund's available earnings and profits.
 
     Because the Funds may invest in private activity bonds, the interest on
which is not federally tax-exempt to persons who are "substantial users" of the
facilities financed by such bonds or "related persons" of such "substantial
users," the Funds may not be an appropriate investment for shareholders who are
considered either a "substantial user" or a "related person" within the meaning
of the Code. For additional information, investors should consult their tax
advisers before investing in a Fund.
 
     Federal tax law imposes an alternative minimum tax with respect to both
corporations and individuals. Interest on certain Municipal Obligations, such as
bonds issued to make loans for housing purposes or to private entities (but not
for certain tax-exempt organizations such as universities and non-profit
hospitals), is included as an item of tax preference in determining the amount
of a taxpayer's alternative minimum taxable income. To the extent that a Fund
receives income from Municipal Obligations subject to the alternative minimum
tax, a portion of the dividends paid by it, although otherwise exempt from
federal income tax, will be taxable to shareholders to the extent that their tax
liability is determined under the alternative minimum tax regime. The Funds will
annually supply shareholders with a report indicating the percentage of Fund
income attributable to Municipal Obligations subject to the federal alternative
minimum tax.
 
     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 the
alternative minimum taxable income. Interest on all Municipal Obligations, and
therefore all distributions by the Funds that would otherwise be tax-exempt, is
included in calculating a corporation's adjusted current earnings.
 
     Tax-exempt income, including exempt-interest dividends paid by a Fund, will
be added to the taxable income of individuals receiving social security or
railroad retirement benefits in determining whether a portion of that benefit
will be subject to federal income tax.
 
     The Code provides that interest on indebtedness incurred or continued to
purchase or carry shares of any Fund is not deductible. Under rules used by the
IRS for determining when borrowed funds are considered used for the purpose of
purchasing or carrying particular assets, the purchase of shares of a Fund may
be considered to have been made with borrowed funds even though such funds are
not directly traceable to the purchase of shares.
 
     The Funds are required in certain circumstances to withhold 31% of taxable
dividends and certain other payments paid to non-corporate holders of shares who
have not furnished to the Funds their correct taxpayer identification number (in
the case of individuals, their social security number) and certain
certifications, or who are otherwise subject to backup withholding.

     The foregoing is a general and abbreviated summary of the provisions of the
Code and Treasury Regulations presently in effect as they directly govern the
taxation of the Fund and its shareholders. For complete provisions, reference
should be made to the pertinent Code sections and Treasury Regulations. The Code
and Treasury Regulations are subject to change by legislative or administrative
action, and any such change may be retroactive with respect to Fund
transactions. Shareholders are advised to consult their own tax advisers for
more detailed information concerning the federal taxation of the Funds and the
income tax consequences to their shareholders.
 
STATE TAX MATTERS
 
     The discussion of tax treatment is based on the assumptions that the Funds
will qualify under Subchapter M of the Code as regulated investment companies
and as qualified investment funds under applicable state law, that they will
satisfy the conditions which will cause distributions to qualify as
exempt-interest dividends to shareholders when distributed as intended, and that
each Fund will distribute all interest and dividends it receives to its
shareholders. Unless otherwise noted, shareholders in each Fund will not be
subject to state income taxation on distributions that are attributable to
interest earned on the municipal obligations issued by that state or its
subdivisions, or on obligations of the United States. Shareholders generally
will be required to include capital gain distributions in their income for state
tax purposes. The tax discussion summarizes general state tax laws which are
currently in effect and are subject to change by legislative or administrative
action; any such changes may be retroactive with respect to the applicable
Fund's transactions. Investors should consult a tax adviser for more detailed
information about state taxes to which they may be subject.

TENNESSEE
 
     The following is a general, abbreviated summary of certain provisions of

the taxation of resident individual and corporate shareholders of the Tennessee
Fund. This summary does not address the taxation of other shareholders nor does
it discuss any local
 
                                      C-25
<PAGE>   221
 
taxes that may be applicable. These provisions are subject to change by
legislative or administrative action, and any such change may be retroactive
with respect to Tennessee Fund transactions.
 
     The following is based on the assumptions that the Tennessee Fund will
qualify under Subchapter M of the Code as a regulated investment company, that
it will invest at least 75% of its assets in obligations of Tennessee and its
political subdivisions ("Tennessee Obligations") or obligations of the United
States, its territories, possessions, or instrumentalities that are exempt from
state taxation under federal law ("Federal Obligations"), that it will satisfy
the conditions which will cause Tennessee Fund distributions to qualify as
exempt-interest dividends to shareholders, and that it will distribute all
interest and dividends it receives to the Tennessee Fund's shareholders.
 
     The Tennessee Fund is not subject to Tennessee taxes.
 
     Distributions from the Tennessee Fund that are attributable to interest on
Tennessee Obligations or to interest on Federal Obligations will not be subject
to the Tennessee individual income tax (also known as the "Hall income tax"). In
addition, under current administrative practice of the Tennessee Department of
Revenue, dividends attributable to gains realized from the sale or exchange of
Tennessee Obligations or Federal Obligations will not be subject to the
Tennessee individual income tax. All other distributions will be subject to such
tax.
 
     All distributions from the Tennessee Fund, regardless of source, will be
subject to the Tennessee corporate excise tax.
 
     Gain on the sale, exchange, or other disposition of shares of the Tennessee
Fund will not be subject to the Tennessee individual income tax but will be
subject to the Tennessee corporate excise tax.
 
     Shares of the Tennessee Fund may be subject to the Tennessee inheritance
tax and the Tennessee estate tax if owned by a Tennessee decedent at the time of
death.
 
     Shareholders are advised to consult with their own tax advisers for more
detailed information concerning Tennessee and local tax matters.
 
                            PERFORMANCE INFORMATION
 
     The historical investment performance of the Funds may be shown in the form
of "yield," "taxable equivalent yield," "average annual total return,"
"cumulative total return" and "taxable equivalent total return" figures, each of
which will be calculated separately for each class of shares.
 
     In accordance with a standardized method prescribed by rules of the
Securities and Exchange Commission ("SEC"), yield is computed by dividing the
net investment income per share earned during the specified one month or 30-day
period by the maximum offering price per share on the last day of the period,
according to the following formula:
 
                                      a-b
                          Yield = 2 [       +1  6 - 1]
                                     (        )
                                       cd
 
     In the above formula, a = dividends and interest earned during the period;
b = expenses accrued for the period (net of reimbursements); c = the average
daily number of shares outstanding during the period that were entitled to
receive dividends; and d = the maximum offering price per share on the last day
of the period. In the case of Class A shares, the maximum offering price
includes the current maximum front-end sales charge of 4.20%.
 
     In computing yield, the Funds follow certain standardized accounting
practices specified by SEC rules. These practices are not necessarily consistent
with those that the Funds use to prepare their annual and interim financial
statements in conformity with generally accepted accounting principles. Thus,
yield may not equal the income paid to shareholders or the income reported in a
Fund's financial statements.
 
     Taxable equivalent yield is computed by dividing that portion of the yield
which is tax-exempt by the remainder of (1 minus the stated combined federal and
state income tax rate, taking into account the deductibility of state taxes for
federal income tax purposes) and adding the product to that portion, if any, of
the yield that is not tax exempt.

combined federal and state income tax rates and (2) the yields for the 30-day
period quoted in the left-hand column.

* The combined tax rates used in these tables represent the highest or one of
  the highest combined tax rates applicable to state taxpayers, rounded to the
  nearest .5%; these rates do not reflect the current federal tax limitations on
  itemized deductions and personal exemptions, which may raise the effective tax
  rate and taxable equivalent yield for taxpayers above certain income levels.
 
     For additional information concerning taxable equivalent yields, see the
Taxable Equivalent Yields table in the Prospectus.
 
     The Funds may from time to time in their advertising and sales materials
report a quotation of their current distribution rate. The distribution rate
represents a measure of dividends distributed for a specified period.
Distribution rate is computed by taking the most recent monthly tax-free income
dividend per share, multiplying it by 12 to annualize it, and dividing by the
appropriate price per share (e.g., net asset value for purchases to be made
without a load such as reinvestments from Nuveen UITs, or the maximum public
offering price). The distribution rate differs from yield and total return and
therefore is not intended to be a complete measure of performance. Distribution
rate may sometimes differ from yield because a Fund may be paying out more than
it is earning and because it may not include the effect of amortization of bond
premiums to the extent such premiums arise after the bonds were purchased.

     Average annual total return quotation is computed in accordance with a
standardized method prescribed by SEC rules. The average annual total return for
a specific period is found by taking a hypothetical, $1,000 investment ("initial
investment") in Fund shares on the first day of the period, reducing the amount
to reflect the maximum sales charge, and computing the "redeemable value" of
that investment at the end of the period. The redeemable value is then divided
by the initial investment, and this quotient is taken to the Nth root (N
representing the number of years in the period) and 1 is subtracted from the
result, which is then expressed as a percentage. The calculation assumes that
all income and capital gains distributions have been reinvested in Fund shares
at net asset value on the reinvestment dates during the period.
 
     Total returns for the Class A Shares of each fund reflect actual
performance for all periods. For the Alabama, Georgia, Louisiana, North
Carolina, South Carolina, and Tennessee Funds, the Class B, C and R Shares,
total returns reflect actual performance for periods since class inception, and
the Class A Shares' performance for periods prior to inception, adjusted for the
differences in sales charges (and for Class B and C, fees) between the classes.
 
     The inception dates for each class of the Funds' shares are as follows:

     Calculation of cumulative total return is not subject to a prescribed
formula. Cumulative total return for a specific period is calculated by first
taking a hypothetical initial investment in Fund shares on the first day of the
period, deducting (in some cases) the maximum sales charge, and computing the
"redeemable value" of that investment at the end of the period. The cumulative
total return percentage is then determined by subtracting the initial investment
from the redeemable value and dividing the remainder by the initial investment
and expressing the result as a percentage. The calculation assumes that all
income and capital gains distributions by the Fund have been reinvested at net
asset value on the reinvestment dates during the period. Cumulative total return
may also be shown as the increased dollar value of the hypothetical investment
over the period. Cumulative total return calculations that do not include the
effect of the sales charge would be reduced if such charge were included.

prescribed formula. Taxable equivalent total return for a specific period is
calculated by first taking a hypothetical initial investment in Fund shares on
the first day of the period, computing the total return for each calendar year
in the period in the manner described above, and increasing the total return for
each such calendar year by the amount of additional income that a taxable fund
would need to have generated to equal the income on an after-tax basis, at a
specified income tax rate (usually the highest marginal federal tax rate),
calculated as described above under the discussion of "taxable equivalent
yield." The resulting amount for the calendar year is then divided by the
initial investment amount to arrive at a "taxable equivalent total return
factor" for the calendar year. The taxable equivalent total return factors for
all the calendar years are then multiplied together and the result is then
annualized by taking its Nth root (N representing the number of years in the
period) and subtracting 1, which provides a taxable equivalent total return
expressed as a percentage.
 
     Using the 41.5% maximum combined marginal federal and State tax rate for
1997, the annual taxable equivalent total return for the Alabama Municipal
Fund's Class A shares for the one-year period ended May 31, 1997 was 13.17%.
 
     Class A Shares of the Funds are sold at net asset value plus a current
maximum sales charge of 4.20% of the offering price. This current maximum sales
charge will typically be used for purposes of calculating performance figures.
Yield, returns and net asset value of each class of shares of the Funds will
fluctuate. Factors affecting the performance of the Funds include general market
conditions, operating expenses and investment management. Any

additional fees charged by a securities representative or other financial
services firm would reduce returns described in this section. Shares of the
Funds are redeemable at net asset value, which may be more or less than original
cost.
 
     In reports or other communications to shareholders or in advertising and
sales literature, the Funds may also compare their performance with that of: (1)
the Consumer Price Index or various unmanaged bond indexes such as the Lehman
Brothers Municipal Bond Index and the Salomon Brothers High Grade Corporate Bond
Index and (2) other fixed income or municipal bond mutual funds or mutual fund
indexes as reported by Lipper Analytical Services, Inc. ("Lipper"), Morningstar,
Inc. ("Morningstar"), Wiesenberger Investment Companies Service ("Wiesenberger")
and CDA Investment Technologies, Inc. ("CDA") or similar independent services
which monitor the performance of mutual funds, or other industry or financial
publications such as Barron's, Changing Times, Forbes and Money Magazine.
Performance comparisons by these indexes, services or publications may rank
mutual funds over different periods of time by means of aggregate, average,
year-by-year, or other types of total return and performance figures. Any given
performance quotation or performance comparison should not be considered as
representative of the performance of the Funds for any future period.
 
     Each fund may from time to time in its advertising and sales materials
compare its current yield or total return with the yield or total return on
taxable investments such as corporate or U.S. Government bonds, bank
certificates of deposit (CDs) or money market funds. These taxable investments
have investment characteristics that differ from those of the Funds. U.S.
Government bonds, for example, are long-term investments backed by the full
faith and credit of the U.S. Government, and bank CDs are generally short-term,
FDIC-insured investments, which pay fixed principal and interest but are subject
to fluctuating rollover rates. Money market funds are short-term investments
with stable net asset values, fluctuating yields and special features enhancing
liquidity.
 
     There are differences and similarities between the investments which the
Funds may purchase and the investments measured by the indexes and reporting
services which are described herein. The Consumer Price Index is generally
considered to be a measure of inflation. The CDA Mutual Fund-Municipal Bond
Index is a weighted performance average of other mutual funds with a federally
tax-exempt income objective. The Salomon Brothers High Grade Corporate Bond
Index is an unmanaged index that generally represents the performance of high
grade long-term taxable bonds during various market conditions. The Lehman
Brothers Municipal Bond Index is an unmanaged index that generally represents
the performance of high grade intermediate and long-term municipal bonds during
various market conditions. Lipper calculates municipal bond fund averages based
on average maturity and credit quality. Morningstar rates mutual funds by
overall risk-adjusted performance, investment objectives, and assets. Lipper,
Morningstar, Wiesenberger and CDA are widely recognized mutual fund reporting
services whose performance calculations are based upon changes in net asset
value with all dividends reinvested and which do not include the effect of any
sales charges. The market prices and yields of taxable and tax-exempt bonds will
fluctuate. The Funds primarily invest in investment grade Municipal Obligations
in pursuing their objective of as high a level of current interest income which
is exempt from federal and state income tax as is consistent, in the view of the
Funds' management, with preservation of capital.
 
     The Funds may also compare their taxable equivalent total return
performance to the total return performance of taxable income funds such as
treasury securities funds, corporate bond funds (either investment grade or high
yield), or Ginnie Mae funds. These types of funds, because of the character of
their underlying securities, differ from municipal bond funds in several
respects. The susceptibility of the price of treasury bonds to credit risk is
far less than that of municipal bonds, but the price of treasury bonds tends to
be slightly more susceptible to change resulting from changes in market interest
rates. The susceptibility of the price of investment grade corporate bonds and
municipal bonds to market interest rate changes and general credit changes is
similar. High yield bonds are subject to a greater degree of price volatility
than municipal bonds resulting from changes in market interest rates and are
particularly susceptible to volatility from credit changes. Ginnie Mae bonds are
generally subject to less price volatility than municipal bonds from credit
concerns, due primarily to the fact that the timely payment of monthly
installments of principal and interest are backed by the full faith and credit
of the U.S. Government, but Ginnie Mae bonds of equivalent coupon and maturity
are generally more susceptible to price volatility resulting from market
interest rate changes. In addition, the volatility of Ginnie Mae bonds due to
changes in market interest rates may differ from municipal bonds of comparable
coupon and maturity because bonds of the sensitivity of Ginnie Mae prepayment
experience to change in interest rates.
 
                   ADDITIONAL INFORMATION ON THE PURCHASE AND
                           REDEMPTION OF FUND SHARES
 
     As described in the Prospectus, the Funds provide you with alternative ways
of purchasing Fund shares based upon your individual investment needs and
preferences.
                                      C-31
<PAGE>   227
 
     Each class of shares of a Fund represents an interest in the same portfolio
of investments. Each class of shares is identical in all respects except that
each class bears its own class expenses, including distribution and
administration expenses, and each class has exclusive voting rights with respect
to any distribution or service plan applicable to its shares. As a result of the
differences in the expenses borne by each class of shares, net income per share,
dividends per share and net asset value per share will vary among a Fund's
classes of shares.
 
     Shareholders of each class will share expenses proportionately for services
that are received equally by all shareholders. A particular class of shares will
bear only those expenses that are directly attributable to that class, where the
type or amount of services received by a class varies from one class to another.
For example, class-specific expenses generally will include distribution and
service fees.
 
     The minimum initial investment is $3,000 per fund share class, and may be
lower for accounts opened through fee-based programs for which the program
sponsor has established a single master account with the fund's transfer agent
and performs all sub-accounting services related to that account.
 
REDUCTION OR ELIMINATION OF UP-FRONT SALES CHARGE ON CLASS A SHARES AND CLASS R
SHARE PURCHASE ELIGIBILITY
 
     Rights of Accumulation. You may qualify for a reduced sales charge on a
purchase of Class A Shares of any Fund if the amount of your purchase, when
added to the value that day of all of your prior purchases of shares of any Fund
or of another Nuveen Mutual Fund, or units of a Nuveen unit trust, on which an
up-front sales charge or ongoing distribution fee is imposed, or is normally
imposed, falls within the amounts stated in the Class A Sales Charges and
Commissions table in "How to Select a Purchase Option" in the Prospectus. You or
your financial adviser must notify Nuveen or the Fund's transfer agent of any
cumulative discount whenever you plan to purchase Class A Shares of a Fund that
you wish to qualify for a reduced sales charge.
 
     Letter of Intent. You may qualify for a reduced sales charge on a purchase
of Class A Shares of any Fund if you plan to purchase Class A Shares of Nuveen
Mutual Funds over the next 13 months and the total amount of your purchases
would, if purchased at one time, qualify you for one of the reduced sales
charges shown in the Class A Sales Charges and Commissions table in "How to
Select a Purchase Option" in the Prospectus. In order to take advantage of this
option, you must complete the applicable section of the Application Form or sign
and deliver either to an Authorized Dealer or to the Fund's transfer agent a
written Letter of Intent in a form acceptable to Nuveen. A Letter of Intent
states that you intend, but are not obligated, to purchase over the next 13
months a stated total amount of Class A Shares that would qualify you for a
reduced sales charge shown above. You may count shares of a Nuveen Mutual Fund
that you already own on which you paid an up-front sales charge or an ongoing
distribution fee and any Class B or C Shares of a Nuveen Mutual Fund that you
purchase over the next 13 months towards completion of your investment program,
but you will receive a reduced sales charge only on new Class A Shares you
purchase with a sales charge over the 13 months. You cannot count towards
completion of your investment program Class A Shares that you purchase without a
sales charge through investment of distributions from a Nuveen Mutual Fund or a
Nuveen Unit Trust or otherwise.
 
     By establishing a Letter of Intent, you agree that your first purchase of
Class A Shares of a Fund following execution of the Letter of Intent will be at
least 5% of the total amount of your intended purchases. You further agree that
shares representing 5% of the total amount of your intended purchases will be
held in escrow pending completion of these purchases. All dividends and capital
gains distributions on Class A Shares held in escrow will be credited to your
account. If total purchases, less redemptions, prior to the expiration of the 13
month period equal or exceed the amount specified in your Letter of Intent, the
Class A Shares held in escrow will be transferred to your account. If the total
purchases, less redemptions, exceed the amount specified in your Letter of
Intent and thereby qualify for a lower sales charge than the sales charge
specified in your Letter of Intent, you will receive this lower sales charge
retroactively, and the difference between it and the higher sales charge paid
will be used to purchase additional Class A Shares on your behalf. If the total
purchases, less redemptions, are less than the amount specified, you must pay
Nuveen an amount equal to the difference between the amounts paid for these
purchases and the amounts which would have been paid if the higher sales charge
had been applied. If you do not pay the additional amount within 20 days after
written request by Nuveen or your financial adviser, Nuveen will redeem an
appropriate number of your escrowed Class A Shares to meet the required payment.
By establishing a Letter of Intent, you irrevocably appoint Nuveen as attorney
to give instructions to redeem any or all of your escrowed shares, with full
power of substitution in the premises.
 
     You or your financial adviser must notify Nuveen or the Fund's transfer
agent whenever you make a purchase of Fund shares that you wish to be covered
under the Letter of Intent option.

     Reinvestment of Nuveen Unit Trust Distributions. You may purchase Class A
Shares without an up-front sales charge by reinvestment of distributions from
any of the various unit trusts sponsored by Nuveen. There is no initial or
subsequent minimum investment requirement for such reinvestment purchases.
 
     Group Purchase Programs. If you are a member of a qualified group, you may
purchase Class A Shares of any Fund or of another Nuveen Mutual Fund at the
reduced sales charge applicable to the group's purchases taken as a whole. A
"qualified group" is one which has previously been in existence, has a purpose
other than investment, has ten or more participating members, has agreed to
include Fund sales publications in mailings to members and has agreed to comply
with certain administrative requirements relating to its group purchases.
 
     Under any group purchase program, the minimum initial investment in Class A
Shares of any particular Fund or portfolio for each participant in the program
is $3,000 and the minimum monthly investment in Class A Shares of any particular
Fund or portfolio by each participant is $50. No certificates will be issued for
any participant's account. All dividends and other distributions by a Fund will
be reinvested in additional Class A Shares of the same Fund. No participant may
utilize a systematic withdrawal program.
 
     To establish a group purchase program, both the group itself and each
participant must fill out special application materials, which the group
administrator may obtain from the group's financial adviser, by calling Nuveen
toll-free (800) 621-7227.
 
     Reinvestment of Redemption Proceeds from Unaffiliated Funds. You may also
purchase Class A Shares at net asset value without a sales charge if the
purchase takes place through a broker-dealer and represents the reinvestment of
the proceeds of the redemption of shares of one or more registered investment
companies not affiliated with Nuveen. You must provide appropriate documentation
that the redemption occurred not more than one year prior to the reinvestment of
the proceeds in Class A Shares, and that you either paid an up-front sales
charge or were subject to a contingent deferred sales charge in respect of the
redemption of such shares of such other investment company.
 
     Special Sales Charge Waivers. Class A Shares of a Fund may be purchased at
net asset value without a sales charge, and Class R Shares may be purchased, by
the following categories of investors:
 
     - officers, trustees and former trustees of the Nuveen and Flagship Funds;
 
     - bona fide, full-time and retired employees of Nuveen, any parent company
       of Nuveen, and subsidiaries thereof, or their immediate family members;
 
     - any person who, for at least 90 days, has been an officer, director or
       bona fide employee of any Authorized Dealer, or their immediate family
       members;
 
     - officers and directors of bank holding companies that make Fund shares
       available directly or through subsidiaries or bank affiliates or their
       immediate family members;
 
     - bank or broker-affiliated trust departments investing funds over which
       they exercise exclusive discretionary investment authority and that are
       held in a fiduciary, agency, advisory, custodial or similar capacity;
 
     - investors purchasing on a periodic fee, asset-based fee or no transaction
       fee basis through a broker-dealer sponsored mutual fund purchase program;
 
     - clients of investment advisers, financial planners or other financial
       intermediaries that charge periodic or asset-based fees for their
       services.
 
     Holders of Class C Shares acquired on or before January 31, 1997 can
convert those shares to Class A Shares of the same fund at the shareholder's
affirmative request six years after the date of purchase. Holders of Class C
Shares must submit their request to the transfer agent no later than the last
business day of the 71st month following the month in which they purchased their
shares. Holders of Class C Shares purchased after that date will not have the
option to convert those shares to Class A Shares.
 
     Any Class A Shares purchased pursuant to a special sales charge waiver must
be acquired for investment purposes and on the condition that they will not be
transferred or resold except through redemption by the Funds. You or your
financial adviser must notify Nuveen or the Fund's transfer agent whenever you
make a purchase of Class A Shares of any Fund that you wish to be covered under
these special sales charge waivers.
 
     Class A Shares of any Fund may be issued at net asset value without a sales
charge in connection with the acquisition by a Fund of another investment
company. All purchases under the special sales charge waivers will be subject to
minimum purchase requirements as established by the Funds.
 
                                      C-33
<PAGE>   229
 
     In determining the amount of your purchases of Class A Shares of any Fund
that may qualify for a reduced sales charge, the following purchases may be
combined: (1) all purchases by a trustee or other fiduciary for a single trust,
estate or fiduciary account; (2) all purchases by individuals and their
immediate family members (i.e., their spouses, parents, children, grandparents,
grandchildren, parents-in-law, sons- and daughters-in-law, siblings, a sibling's
spouse, and a spouse's siblings); or (3) all purchases made through a group
purchase program as described above.
 
     Class R Share Purchase Eligibility. Class R Shares are available for
purchases of $1 million or more and for purchases using dividends and capital
gains distributions on Class R Shares. Class R Shares also are available for the
following categories of investors:
 
     - officers, trustees and former trustees of the Nuveen and Flagship Funds;
 
     - bona fide, full-time and retired employees of Nuveen, any parent company
       of Nuveen, and subsidiaries thereof, or their immediate family members;
 
     - any person who, for at least 90 days, has been an officer, director or
       bona fide employee of any Authorized Dealer, or their immediate family
       members;
 
     - officers and directors of bank holding companies that make Fund shares
       available directly or through subsidiaries or bank affiliates, or their
       immediate family members;
 
     - bank or broker-affiliated trust departments investing funds over which
       they exercise exclusive discretionary investment authority and that are
       held in a fiduciary, agency, advisory, custodial or similar capacity;
 
     - investors purchasing on a periodic fee, asset-based fee or no transaction
       fee basis through a broker-dealer sponsored mutual fund purchase program;
 
     - clients of investment advisers, financial planners or other financial
       intermediaries that charge periodic or asset-based fees for their
       services.
 
     In addition, purchasers of Nuveen unit trusts may reinvest their
distributions from such unit trusts in Class R Shares, if, before September 6,
1994, such purchasers had elected to reinvest distributions in Nuveen Fund
shares (before June 13, 1995 for Nuveen Municipal Bond Fund shares).
Shareholders may exchange their Class R Shares of any Nuveen Fund into Class R
Shares of any other Nuveen Fund.
 
     The reduced sales charge programs may be modified or discontinued by the
Funds at any time upon prior written notice to shareholders of the Funds.
 
     For more information about the purchase of Class A Shares or reduced sales
charge programs, or to obtain the required application forms, call Nuveen
toll-free at (800) 621-7227.
 
REDUCTION OR ELIMINATION OF CONTINGENT DEFERRED SALES CHARGE
 
     Class A Shares are normally redeemed at net asset value, without any
Contingent Deferred Sales Charge ("CDSC"). However, in the case of Class A
Shares purchased at net asset value on or after July 1, 1996 because the
purchase amount exceeded $1 million, where the Authorized Dealer did not waive
the sales commission, a CDSC of 1% is imposed on any redemption within 18 months
of purchase. In the case of Class B Shares redeemed within six years of
purchase, a CDSC is imposed, beginning at 5% for redemptions within the first
year, declining to 4% for redemptions within years two and three, and declining
by 1% each year thereafter until disappearing after the sixth year. Class C
Shares are redeemed at net asset value, without any CDSC, except that a CDSC of
1% is imposed upon redemption of Class C Shares that are redeemed within 12
months of purchase.
 
     In determining whether a CDSC is payable, a Fund will first redeem shares
not subject to any charge, or that represent an increase in the value of a Fund
account due to capital appreciation, and then will redeem shares held for the
longest period, unless the shareholder specifies another order. No CDSC is
charged upon shares purchased as a result of automatic reinvestment of dividends
or capital gains paid. In addition, no CDSC will be charged on exchanges of
shares into another Nuveen Mutual Fund or Nuveen money market fund. You may not
exchange Class B Shares for shares of a Nuveen money market fund. The holding
period is calculated on a monthly basis and begins the first day of the month in
which the order for investment is received. The CDSC is calculated based on the
lower of the redeemed shares' cost or net asset value at the time of the
redemption and is deducted from the redemption proceeds. Nuveen receives the
amount of any CDSC shareholders pay. If Class A or Class C Shares subject to a
CDSC are exchanged for shares of a Nuveen money market fund, the CDSC would be
imposed on the subsequent redemption of those money market shares, and the
period during which the shareholder holds the money
 
                                      C-34
<PAGE>   230
 
market fund shares would be counted in determining the remaining duration of the
CDSC. The Fund may elect not to so count the period during which the shareholder
held the money market fund shares, in which event the amount of any applicable
CDSC would be reduced in accordance with applicable SEC rules by the amount of
any 12b-1 plan payments to which those money market funds shares may be subject.
 
     The CDSC may be waived or reduced under the following six special
circumstances: 1) redemptions within one year following the death or disability,
as defined in Section 72(m)(7) of the Internal Revenue Code of 1986, as amended,
of a shareholder; 2) in whole or in part for redemptions of shares by
shareholders with accounts in excess of specified breakpoints that correspond to
the breakpoints under which the up-front sales charge on Class A Shares is
reduced pursuant to Rule 22d-1 under the Act; 3) redemptions of shares purchased
under circumstances or by a category of investors for which Class A Shares could
be purchased at net asset value without a sales charge; 4) in connection with
the exercise of a reinstatement privilege whereby the proceeds of a redemption
of a Fund's shares subject to a sales charge are reinvested in shares of certain
Funds within a specified number of days; 5) in connection with the exercise of a
Fund's right to redeem all shares in an account that does not maintain a certain
minimum balance or that the applicable board has determined may have material
adverse consequences to the shareholders of such Fund; and 6) redemptions made
pursuant to a Fund's systematic withdrawal plan, up to 12% of the original
investment amount. If a Fund waives or reduces the CDSC, such waiver or
reduction would be uniformly applied to all Fund shares in the particular
category. In waiving or reducing a CDSC, the Funds will comply with the
requirements of Rule 22d-1 of the Investment Company Act of 1940, as amended.
 
GENERAL MATTERS
 
     The Funds may encourage registered representatives and their firms to help
apportion their assets among bonds, stocks and cash, and may seek to participate
in programs that recommend a portion of their assets be invested in tax-free,
fixed income securities.
 
     In addition to the types of compensation to dealers to promote sales of
fund shares that are described in the prospectus, Nuveen may from time to time
make additional reallowances only to certain authorized dealers who sell or are
expected to sell certain minimum amounts of shares of the Nuveen mutual funds
during specified time periods.
 
     To help advisers and investors better understand and most efficiently use
the Funds to reach their investment goals, the Funds may advertise and create
specific investment programs and systems. For example, this may include
information on how to use the Funds to accumulate assets for future education
needs or periodic payments such as insurance premiums. The Funds may produce
software, electronic information sites, or additional sales literature to
promote the advantages of using the Funds to meet these and other specific
investor needs.
 
     Exchanges of shares of a Fund for shares of a Nuveen money market fund may
be made on days when both funds calculate a net asset value and make shares
available for public purchase. Shares of the Nuveen money market funds may be
purchased on days on which the Federal Reserve Bank of Boston is normally open
for business. In addition to the holidays observed by the Fund, the Nuveen money
market funds observe and will not make fund shares available for purchase on the
following holidays: Martin Luther King's Birthday, Columbus Day and Veterans
Day.
 
     In addition, you may exchange Class R Shares of any Fund for Class A Shares
of the same Fund without a sales charge if the current net asset value of those
Class R Shares is at least $3,000 or you already own Class A Shares of that
Fund.
 
     Each Fund may suspend the right of redemption, or delay payment to
redeeming shareholders for more than seven days, when the New York Stock
Exchange is closed (not including customary weekend and holiday closings); when
trading in the markets a Fund normally uses is restricted, or the SEC determines
that an emergency exists so that trading of a Fund's portfolio securities or
determination of a Fund's net asset value is not reasonably practical; or the
SEC by order permits the suspension of the right of redemption or the delay in
payment to redeeming shareholders for more than seven days.
 
     Shares will be registered in the name of the investor or the investor's
financial adviser. A change in registration or transfer of shares held in the
name of a financial adviser may only be made by an order in good form from the
financial adviser acting on the investor's behalf. Share certificates will only
be issued upon written request to the Funds' transfer agent. No share
certificates will be issued for fractional shares.
 
     For more information on the procedure for purchasing shares of a Fund and
on the special purchase programs available thereunder, see "How to Buy Fund
Shares" in the Prospectus.

     Nuveen serves as the principal underwriter of the shares of the Funds
pursuant to a "best efforts" arrangement as provided by a distribution agreement
with the Nuveen Flagship Multistate Trust III, dated February 1, 1997
("Distribution Agreement"). Pursuant to the Distribution Agreement, the Trust
appointed Nuveen to be its agent for the distribution of the Funds' shares on a
continuous offering basis. Nuveen sells shares to or through brokers, dealers,
banks or other qualified financial intermediaries (collectively referred to as
"Dealers"), or others, in a manner consistent with the then effective
registration statement of the Trust. Pursuant to the Distribution Agreement,
Nuveen, at its own expense, finances certain activities incident to the sale and
distribution of the Funds' shares, including printing and distributing of
prospectuses and statements of additional information to other than existing
shareholders, the printing and distributing of sales literature, advertising and
payment of compensation and giving of concessions to Dealers. Nuveen receives
for its services the excess, if any, of the sales price of the Funds' shares
less the net asset value of those shares, and reallows a majority or all of such
amounts to the Dealers who sold the shares; Nuveen may act as such a Dealer.
Nuveen also receives compensation pursuant to a distribution plan adopted by the
Trust pursuant to Rule 12b-1 and described herein under "Distribution and
Service Plan." Nuveen receives any CDSCs imposed on redemptions of Shares.
 
     The following table sets forth the aggregate amount of underwriting
commissions with respect to the sale of Fund shares and the amount thereof
retained by Nuveen (or Flagship Financial, Inc., which Nuveen acquired on
January 1, 1997) for each of the Funds for the last three fiscal years. All
figures are to the nearest thousand.

                         DISTRIBUTION AND SERVICE PLAN
 
     The Funds have adopted a plan (the "Plan") pursuant to Rule 12b-1 under the
Investment Company Act of 1940, which provides that Class B Shares and Class C
Shares will be subject to an annual distribution fee, and that Class A Shares,
Class B Shares and Class C Shares will be subject to an annual service fee.
Class R Shares will not be subject to either distribution or service fees.
 
     The distribution fee applicable to Class B and Class C Shares under each
Fund's Plan will be payable to reimburse Nuveen for services and expenses
incurred in connection with the distribution of Class B and Class C Shares,
respectively. These expenses include payments to Authorized Dealers, including
Nuveen, who are brokers of record with respect to the Class B and Class C
Shares, as well as, without limitation, expenses of printing and distributing
prospectuses to persons other than shareholders of the Fund, expenses of
preparing, printing and distributing advertising and sales literature and
reports to shareholders used in connection with the sale of Class B and Class C
Shares, certain other expenses associated with the distribution of Class B and
Class C Shares, and any distribution-related expenses that may be authorized
from time to time by the Board of Trustees.
 
     The service fee applicable to Class A Shares, Class B Shares and Class C
Shares under each Fund's Plan will be payable to Authorized Dealers in
connection with the provision of ongoing account services to shareholders. These
services may include establishing and maintaining shareholder accounts,
answering shareholder inquiries and providing other personal services to
shareholders.
 
     Each Fund may spend up to .20 of 1% per year of the average daily net
assets of Class A Shares as a service fee under the Plan applicable to Class A
Shares. Each Fund may spend up to .75 of 1% per year of the average daily net
assets of Class B Shares as a distribution fee and up to .20 of 1% per year of
the average daily net assets of Class B Shares as a service fee under the Plan
applicable to Class B Shares. Each Fund may spend up to .55 of 1% per year of
the average daily net assets of Class C Shares as a distribution fee and up to
 .20 of 1% per year of the average daily net assets of Class C Shares as a
service fee under the Plan applicable to Class C Shares.
 
     For the fiscal year ended May 31, 1997, 100% of service fees and
distribution fees were paid out as compensation to Authorized Dealers. For the
period from June 1, 1996 to January 31, 1997, the service fee for all Class C
Shares was .20% and the distribution fee was .40% for the Class A Shares and
 .75% for the Class C Shares.

Thereafter, the service fee for the Class A and Class C Shares was .20% and the
distribution fee for the Class B Shares was .75% and for the Class C Shares was
 .55%.

     Under each Fund's Plan, the Fund will report quarterly to the Board of
Trustees for its review all amounts expended per class of shares under the Plan.
The Plan may be terminated at any time with respect to any class of shares,
without the payment of any penalty, by a vote of a majority of the trustees who
are not "interested persons" and who have no direct or indirect financial
interest in the Plan or by vote of a majority of the outstanding voting
securities of such class. The Plan may be renewed from year to year if approved
by a vote of the Board of Trustees and a vote of the non-interested trustees who
have no direct or indirect financial interest in the Plan cast in person at a
meeting called for the purpose of voting on the Plan. The Plan may be continued
only if the trustees who vote to approve such continuance conclude, in the
exercise of reasonable business judgment and in light of their fiduciary duties
under applicable law, that there is a reasonable likelihood that the Plan will
benefit the Fund and its shareholders. The Plan may not be amended to increase
materially the cost which a class of shares may bear under the Plan without the
approval of the shareholders of the affected class, and any other material
amendments of the Plan must be approved by the noninterested trustees by a vote
cast in person at a meeting called for the purpose of considering such
amendments. During the continuance of the Plan, the selection and nomination of
the non-interested trustees of the Trust will be committed to the discretion of
the non-interested trustees then in office.

                                                                      APPENDIX A
 
                             RATINGS OF INVESTMENTS
 
     The four highest ratings of Moody's for Municipal Obligations are Aaa, Aa,
A and Baa. Municipal Obligations rated Aaa are judged to be of the "best
quality." The rating of Aa is assigned to Municipal Obligations which are of
"high quality by all standards," but as to which margins of protection or other
elements make long-term risks appear somewhat greater than in Aaa rated
Municipal Obligations. The Aaa and Aa rated Municipal Obligations comprise what
are generally known as "high grade bonds." Municipal Obligations that are rated
A by Moody's possess many favorable investment attributes and are considered
upper medium grade obligations. Factors giving security to principal and
interest of A rated Municipal Obligations are considered adequate, but elements
may be present, which suggest a susceptibility to impairment sometime in the
future. Municipal Obligations rated Baa by Moody's are considered medium grade
obligations (i.e., they are neither highly protected nor poorly secured). Such
bonds lack outstanding investment characteristics and in fact have speculative
characteristics as well. Moody's bond rating symbols may contain numerical
modifiers of a generic rating classification. The modifier 1 indicates that the
bond ranks at the high end of its category; the modifier 2 indicates a midrange
ranking; and the modifier 3 indicates that the issue ranks in the lower end of
its general rating category.
 
     The four highest ratings of S&P for Municipal Obligations are AAA, AA, A
and BBB. Municipal Obligations rated AAA have a strong capacity to pay principal
and interest. The rating of AA indicates that capacity to pay principal and
interest is very strong and such bonds differ from AAA issues only in small
degree. The category of A describes bonds which have a strong capacity to pay
principal and interest, although such bonds are somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions. The BBB
rating is the lowest "investment grade" security rating by S&P. Municipal
Obligations rated BBB are regarded as having an adequate capacity to pay
principal and interest. Whereas such bonds normally exhibit adequate protection
parameters, adverse economic conditions are more likely to lead to a weakened
capacity to pay principal and interest for bonds in this category than for bonds
in the A category.
 
     The four highest ratings of Fitch for Municipal Obligations are AAA, AA, A
and BBB. Municipal Obligations rated AAA are considered to be investment grade
and of the highest credit quality. The obligor has an exceptionally strong
ability to pay interest and repay principal, which is unlikely to be affected by
reasonably foreseeable events. Municipal Obligations rated AA are considered to
be investment grade and of very high quality. The obligor's ability to pay
interest and repay principal is very strong, although not quite as strong as
bonds rated "AAA." Because Municipal Obligations rated in the "AAA" and "AA"
categories are not significantly vulnerable to foreseeable future developments,
short-term debt of these issuers is generally rated "F-1+." Municipal
Obligations rated A are considered to be investment grade and of high credit
quality. The obligor's ability to pay interest and repay principal is considered
to be strong, but may be more vulnerable to adverse changes in economic
conditions and circumstances than bonds with higher ratings. Municipal
Obligations rated BBB are considered to be investment grade and of satisfactory
credit quality. The obligor's ability to pay interest and repay principal is
considered to be adequate. Adverse changes in economic conditions and
circumstances, however, are more likely to have adverse impact on these bonds,
and therefore impair timely payment. The likelihood that the ratings of these
bonds will fall below investment grade is higher than for bonds with higher
ratings.
 
     The "Other Corporate Obligations" category of temporary investments are
corporate (as opposed to municipal) debt obligations rated AAA by S&P or Aaa by
Moody's. Corporate debt obligations rated AAA by S&P have an extremely strong
capacity to pay principal and interest. The Moody's corporate debt rating of Aaa
is comparable to that set forth above for Municipal Obligations.
 
     Subsequent to its purchase by a Fund, an issue may cease to be rated or its
rating may be reduced below the minimum required for purchase by such Fund.
Neither event requires the elimination of such obligation from a Fund's
portfolio, but Nuveen Advisory will consider such an event in its determination
of whether the Fund should continue to hold such obligation.

                                                                      APPENDIX B
 
                       DESCRIPTION OF HEDGING TECHNIQUES
 
     Set forth below is additional information regarding the various Fund's
defensive hedging techniques and use of repurchase agreements.
 
FUTURES AND INDEX TRANSACTIONS
 
     Financial Futures. A financial future is an agreement between two parties
to buy and sell a security for a set price on a future date. They have been
designed by boards of trade which have been designated "contracts markets" by
the Commodity Futures Trading Commission ("CFTC").
 
     The purchase of financial futures is for the purpose of hedging a Fund's
existing or anticipated holdings of long-term debt securities. When a Fund
purchases a financial future, it deposits in cash or securities an "initial
margin" of between 1% and 5% of the contract amount. Thereafter, the Fund's
account is either credited or debited on a daily basis in correlation with the
fluctuation in price of the underlying future or other requirements imposed by
the exchange in order to maintain an orderly market. The Fund must make
additional payments to cover debits to its account and has the right to withdraw
credits in excess of the liquidity, the Fund may close out its position at any
time prior to expiration of the financial future by taking an opposite position.
At closing a final determination of debits and credits is made, additional cash
is paid by or to the Fund to settle the final determination and the Fund
realizes a loss or gain depending on whether on a net basis it made or received
such payments.
 
     The sale of financial futures is for the purpose of hedging a Fund's
existing or anticipated holdings of long-term debt securities. For example, if a
Fund owns long-term bonds and interest rates were expected to increase, it might
sell financial futures. If interest rates did increase, the value of long-term
bonds in the Fund's portfolio would decline, but the value of the Fund's
financial futures would be expected to increase at approximately the same rate
thereby keeping the net asset value of the Fund from declining as much as it
otherwise would have.
 
     Among the risks associated with the use of financial futures by the Funds
as a hedging device, perhaps the most significant is the imperfect correlation
between movements in the price of the financial futures and movements in the
price of the debt securities which are the subject of the hedge.
 
     Thus, if the price of the financial future moves less or more than the
price of the securities which are the subject of the hedge, the hedge will not
be fully effective. To compensate for this imperfect correlation, the Fund may
enter into financial futures in a greater dollar amount than the dollar amount
of the securities being hedged if the historical volatility of the prices of
such securities has been greater than the historical volatility of the financial
futures. Conversely, the Fund may enter into fewer financial futures if the
historical volatility of the price of the securities being hedged is less than
the historical volatility of the financial futures.
 
     The market prices of financial futures may also be affected by factors
other than interest rates. One of these factors is the possibility that rapid
changes in the volume of closing transactions, whether due to volatile markets
or movements by speculators, would temporarily distort the normal relationship
between the markets in the financial future and the chosen debt securities. In
these circumstances as well as in periods of rapid and large price movements.
The Fund might find it difficult or impossible to close out a particular
transaction.
 
     Options on Financial Futures. The Funds may also purchase put or call
options on financial futures which are traded on a U.S. Exchange or board of
trade and enter into closing transactions with respect to such options to
terminate an existing position. Currently, options can be purchased with respect
to financial futures on U.S. Treasury Bonds on The Chicago Board of Trade. The
purchase of put options on financial futures is analogous to the purchase of put
options by a Fund on its portfolio securities to hedge against the risk of
rising interest rates. As with options on debt securities, the holder of an
option may terminate his position by selling an option of the same Fund. There
is no guarantee that such closing transactions can be effected.
 
INDEX CONTRACTS
 
     Index Futures. A tax-exempt bond index which assigns relative values to the
tax-exempt bonds included in the index is traded on the Chicago Board of Trade.
The index fluctuates with changes in the market values of all tax-exempt bonds
included rather than a single bond. An index future is a bilateral agreement
pursuant to which two parties agree to take or make delivery of an amount of
cash -- rather than any security -- equal to specified dollar amount times the
difference between the index value at the close of the last trading day of the
contract and the price at which the index future was originally written. Thus,
an index future is similar to traditional financial futures except that
settlement is made in cash.
                                      BB-1
<PAGE>   235
 
     Index Options. The Funds may also purchase put or call options on U.S.
Government or tax-exempt bond index futures and enter into closing transactions
with respect to such options to terminate an existing position. Options on index
futures are similar to options on debt instruments except that an option on an
index future gives the purchaser the right, in return for the premium paid, to
assume a position in an index contract rather than an underlying security at a
specified exercise price at any time during the period of the option. Upon
exercise of the option, the delivery of the futures position by the writer of
the option to the holder of the option will be accompanied by delivery of the
accumulated balance of the writer's futures margin account which represents the
amount by which the market price of the index futures contract, at exercise, is
less than the exercise price of the option on the index future.
 
     Bond index futures and options transactions would be subject to risks
similar to transactions in financial futures and options thereon as described
above. No series will enter into transactions in index or financial futures or
related options unless and until, in the Adviser's opinion, the market for such
instruments has developed sufficiently.
 
REPURCHASE AGREEMENTS
 
     A Fund may invest temporarily up to 5% of its assets in repurchase
agreements, which are agreements pursuant to which securities are acquired by
the Fund from a third party with the understanding that they will be repurchased
by the seller at a fixed price on an agreed date. These agreements may be made
with respect to any of the portfolio securities in which the Fund is authorized
to invest. Repurchase agreements may be characterized as loans secured by the
underlying securities. The Fund may enter into repurchase agreements with (i)
member banks of the Federal Reserve System having total assets in excess of $500
million and (ii) securities dealers, provided that such banks or dealers meet
the creditworthiness standards established by the Fund's board of trustees
("Qualified Institutions"). The Adviser will monitor the continued
creditworthiness of Qualified Institutions, subject to the oversight of the
Fund's board of trustees.
 
     The use of repurchase agreements involves certain risks. For example, if
the seller of securities under a repurchase agreement defaults on its obligation
to repurchase the underlying securities, as a result of its bankruptcy or
otherwise, the Fund will seek to dispose of such securities, which action could
involve costs or delays. If the seller becomes insolvent and subject to
liquidation or reorganization under applicable bankruptcy or other laws, the
Fund's ability to dispose of the underlying securities may be restricted.
Finally, it is possible that the Fund may not be able to substantiate its
interest in the underlying securities. To minimize this risk, the securities
underlying the repurchase agreement will be held by the custodian at all times
in an amount at least equal to the repurchase price, including accrued interest.
If the seller fails to repurchase the securities, the Fund may suffer a loss to
the extent proceeds from the sale of the underlying securities are less than the
repurchase price.
 
     The resale price reflects the purchase price plus an agreed upon market
rate of interest which is unrelated to the coupon rate or date of maturity of
the purchased security. The collateral is marked to market daily. Such
agreements permit the Fund to keep all its assets earning interest while
retaining "overnight" flexibility in pursuit of investments of a longer-term
nature.

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
                                OCTOBER 31, 1997
 
1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES
 
     The Nuveen Flagship Municipal Trust (the "Trust") is an open-end
diversified investment company registered under the Investment Company Act of
1940, as amended. The Trust comprises the Nuveen Flagship All-American Municipal
Bond Fund ("Nuveen Flagship All-American") (the "Fund"), among others. The Trust
was organized as a Massachusetts business trust on July 1, 1996.
 
     The John Nuveen Company ("Nuveen"), parent of John Nuveen & Co.
Incorporated and Nuveen Advisory Corp., respectively, the distributor
("Distributor") and investment advisor ("Adviser") of the Fund, entered into an
agreement under which Nuveen acquired Flagship Resources Inc. and after the
close of business on January 31, 1997, consolidated their respective mutual fund
businesses. This agreement was approved at a meeting by the shareholders of the
Flagship Funds in December 1996.
 
     After the close of business on January 31, 1997, Flagship All-American Tax
Exempt Fund ("Flagship All-American") reorganized into the Trust. At this time
the Fund was renamed Nuveen Flagship All-American Municipal Bond Fund. The Fund
had a May 31 fiscal year end prior to being reorganized into the Trust and now
has an April 30 fiscal year end.
 
     The Fund seeks to provide high tax-free income and preservation of capital
through investments in a diversified portfolio of quality municipal bonds.
 
     The following is a summary of significant accounting policies followed by
the Fund in the preparation of its financial statements in accordance with
generally accepted accounting principles.
 
  Securities Valuation
 
     The prices of municipal bonds in the Fund's investment portfolio are
provided by a pricing service approved by the Fund's Board of Trustees. When
price quotes are not readily available (which is usually the case for municipal
securities), the pricing service establishes fair market value based on yields
or prices of municipal bonds of comparable quality, type of issue, coupon,
maturity and rating, indications of value from securities dealers and general
market conditions. Temporary investments in securities that have variable rate
and demand features qualifying them as short-term securities are valued at
amortized cost, which approximates market value.
 
  Securities Transactions
 
     Securities transactions are recorded on a trade date basis. Realized gains
and losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Fund has instructed the custodian to
segregate assets in a separate account with a current value at least equal to
the amount of their when-issued and delayed delivery purchase commitments. At
October 31, 1997, the Fund had outstanding when-issued purchase commitments of
$3,964,563.
 
  Interest Income
 
     Interest income is determined on the basis of interest accrued, adjusted
for amortization of premiums and accretion of discounts on long-term debt
securities when required for federal income tax purposes.
 
  Dividends and Distributions to Shareholders
 
     Tax-exempt net investment income is declared as a dividend monthly and
payment is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryforwards.
 
     Distributions to shareholders of tax-exempt net investment income, net
realized capital gains and/or market discount are recorded on the ex-dividend
date. The amount and timing of distributions are determined in accordance with
federal income tax regulations, which may differ from generally accepted
accounting principles. Accordingly, temporary over-distributions as a result of
these differences may occur and will be classified as either distributions in

excess of net investment income, distributions in excess of net realized gains
and/or distributions in excess of net ordinary taxable income from investment
transactions, where applicable.
 
  Income Taxes
 
     The Fund is a separate taxpayer for federal income tax purposes. The Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Fund
currently considers significant net realized capital gains and/or market
discount as amounts in excess of $.001 per share. Furthermore, the Fund intends
to satisfy conditions which will enable interest from municipal securities,
which is exempt from regular federal income tax, to retain such tax-exempt
status when distributed to the shareholders of the Fund. Net realized capital
gain and market discount distributions are subject to federal taxation.
 
  Flexible Sales Charge Program
 
     The Fund offers Class A, B, C and R Shares. Class A Shares are sold with a
sales charge and incur an annual 12b-1 service fee. Class A Share purchases of
$1 million or more are sold at net asset value without an up-front sales charge
but may be subject to a 1% contingent deferred sales charge ("CDSC") if redeemed
within 18 months of purchase. Class B Shares are sold without a sales charge but
incur annual 12b-1 distribution and service fees. An investor purchasing Class B
Shares agrees to pay a CDSC of up to 5% depending upon the length of time the
shares are held by the investor (CDSC is reduced to 0% at the end of six years).
Class B Shares convert to Class A Shares eight years after purchase. Class C
Shares are sold without a sales charge but incur annual 12b-1 distribution and
service fees. An investor purchasing Class C Shares agrees to pay a CDSC of 1%
if Class C Shares are redeemed within one year of purchase. Class R Shares are
not subject to any sales charge or 12b-1 distribution or service fees. Class R
Shares are available for purchases of over $1 million and in other limited
circumstances.
 
  Derivative Financial Instruments
 
     The Fund may invest in certain derivative financial instruments including
futures, forward, swap, option contracts, and other financial instruments with
similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the six months ended October 31, 1997.
 
  Expense Allocation
 
     Expenses of the Fund that are not directly attributable to a specific class
of shares are prorated among the classes based on the relative net assets of
each class. Expenses directly attributable to a class of shares, which presently
only includes 12b-1 distribution and service fees, are recorded to the specific
class.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period.

be terminated at any time at its discretion.

     19% of the long-term and intermediate-term investments owned by the Fund
are either covered by insurance issued by several private insurers or are backed
by an escrow or trust containing U.S. Government or U.S. Government agency
securities, both of which ensure the timely payment of principal and interest in
the event of default. Such insurance or escrow, however, does not guarantee the
market value of the municipal securities or the value of any of the Fund's
shares.
 
     For additional information regarding each investment security, refer to the
Portfolio of Investments of the Fund.

                         NOTES TO FINANCIAL STATEMENTS
 
                                 APRIL 30, 1997
 
1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES
 
     The Nuveen Flagship Municipal Trust (the "Trust") is an open-end
diversified management investment company registered under the Investment
Company Act of 1940, as amended. The Trust comprises the Nuveen Flagship
All-American Municipal Bond Fund ("Nuveen Flagship All-American") (the "Fund"),
among others. The Trust was organized as a Massachusetts business trust on July
1, 1996.
 
     The John Nuveen Company, parent of John Nuveen & Co. Incorporated and
Nuveen Advisory Corp., respectively, the distributor ("Distributor") and
investment advisor ("Adviser") of the Fund, entered into an agreement under
which Nuveen acquired Flagship Resources Inc. and after the close of business on
January 31, 1997, consolidated their respective mutual fund businesses. This
agreement was approved at a meeting by the shareholders of the Flagship Funds in
December 1996.
 
     After the close of business on January 31, 1997, the Flagship All-American
Tax Exempt Fund ("Flagship All-American") reorganized into the Trust. At this
time the Fund was renamed Flagship All-American Municipal Bond Fund. The Fund
had a May 31 fiscal year end prior to being reorganized into the Trust and now
has an April 30 fiscal year end.
 
     The Fund seeks to provide high tax-free income and preservation of capital
through investments in a diversified portfolio of quality municipal bonds.
 
     The following is a summary of significant accounting policies followed by
the Fund in the preparation of its financial statements in accordance with
generally accepted accounting principles.
 
  Securities Valuation
 
     The prices of municipal bonds in the Fund's investment portfolio are
provided by a pricing service approved by the Fund's Board of Trustees. When
price quotes are not readily available (which is usually the case for municipal
securities), the pricing service establishes fair market value based on yields
or prices of municipal bonds of comparable quality, type of issue, coupon,
maturity and rating, indications of value from securities dealers and general
market conditions. Temporary investments in securities that have variable rate
and demand features qualifying them as short-term securities are valued at
amortized cost, which approximates market value.
 
  Securities Transactions
 
     Securities transactions are recorded on a trade date basis. Realized gains
and losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Fund has instructed the custodian to
segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
April 30, 1997, the Fund had such outstanding purchase commitments of
$4,841,206.
 
  Interest Income
 
     Interest income is determined on the basis of interest accrued, adjusted
for amortization of premiums and accretion of discounts on long-term debt
securities as required for federal income tax purposes.
 
  Dividends and Distributions to Shareholders
 
     Tax-exempt net investment income is declared as a dividend monthly and
payment is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions are distributed to shareholders not less frequently
than annually. Furthermore, capital gains are distributed only to the extent
they exceed available capital loss carryovers. Prior to the reorganization,
tax-exempt net investment income for the Fund was declared as a dividend daily
and payment was made on the last business day of each month.
 
     Distributions to shareholders of tax-exempt net investment income, net
realized capital gains and/or market discount are recorded on the ex-dividend
date. The amount and timing of distributions are determined in accordance with
federal income tax regulations, which may differ from generally accepted
accounting principles. Accordingly,
 
                                      D-23
<PAGE>   259
                   NOTES TO FINANCIAL STATEMENTS -- CONTINUED
 
                                 APRIL 30, 1997
 
temporary over-distributions as a result of these differences may occur and will
be classified as either distributions in excess of net investment income,
distributions in excess of net realized gains and/or distributions in excess of
ordinary taxable income from investment transactions, where applicable.
 
  Federal Income Taxes
 
     The Fund is a separate taxpayer for federal income tax purposes. The Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Fund
currently consider significant net realized capital gains and/or market discount
as amounts in excess of $.001 per share. Furthermore, the Fund intends to
satisfy conditions which will enable interest from municipal securities, which
is exempt from regular federal income tax, to retain such tax-exempt status when
distributed to the shareholders of the respective Fund. All income dividends
paid during the 11 months ended April 30, 1997, have been designated Exempt
Interest Dividends. Net realized capital gain and market discount distributions
are subject to federal taxation.
 
  Flexible Sales Charge Program
 
     The Fund offers Class A, Class B, Class C and Class R Shares. Class A
Shares incur a sales charge on purchases and an annual 12b-1 service fee. Class
B Shares, which were first offered for sale on February 1, 1997, are sold
without a sales charge on purchases but incur annual 12b-1 distribution and
service fees. An investor purchasing Class B Shares agrees to pay a contingent
deferred sales charge ("CDSC") of up to 5% depending upon the length of time the
shares are held (CDSC declines to 0% at the end of six years). Class C Shares
are sold without a sales charge on purchases but incur annual 12b-1 distribution
and service fees. An investor purchasing Class C Shares agrees to pay a CDSC of
1% if Class C Shares are redeemed within 12 months of purchase. Class R Shares,
which were first offered for sale on February 1, 1997, are not subject to any
sales charge on purchases or 12b-1 distribution or service fees. Class R Shares
are available for purchases of over $1 million and in other limited
circumstances.
 
  Derivative Financial Instruments
 
     The Fund may invest in certain derivative financial instruments including
futures, forward, swap, and option contracts, and other financial instruments
with similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the 11 months ended April 30, 1997.
 
  Expense Allocation
 
     Expenses of the Fund that are not directly attributable to a specific class
of shares are prorated among the classes based on the relative net assets of
each class. Expenses directly attributable to a class of shares, which presently
only includes 12b-1 distribution and service fees, are recorded to the specific
class.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period.

compensation directly to its Trustees who are affiliated with the Adviser or to
its officers, all of whom receive remuneration for their services to the Trust
from the Adviser.
 
     The Adviser may voluntarily reimburse expenses from time to time, which may
be terminated at any time at its discretion.

     19% of the long-term and intermediate-term investments owned by the Fund
are either covered by insurance issued by several private insurers or are backed
by an escrow or trust containing U.S. Government or U.S. Government agency
securities, both of which ensure the timely payment of principal and interest in
the event of default. Such insurance or escrow, however, does not guarantee the
market value of the municipal securities or the value of any of the Fund's
shares.
 
     For additional information regarding each investment security, refer to the
Portfolio of Investments of the Fund.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Trustees and Shareholders of
Nuveen Flagship All-American Municipal Bond Fund:
 
     We have audited the accompanying statement of net assets of Nuveen Flagship
All-American Municipal Bond Fund including the portfolio of investments, as of
April 30, 1997, the related statement of operations for the period then ended
and the statement of changes in net assets and the financial highlights for each
of the periods presented. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of April
30, 1997, by correspondence with the Fund's custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
     In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Nuveen Flagship
All-American Municipal Bond Fund at April 30, 1997, the results of its
operations, the changes in its net assets and the financial highlights for the
respective stated periods, in conformity with generally accepted accounting
principles.

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
                               NOVEMBER 30, 1997
 
1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES
 
     The Nuveen Flagship Multistate Trust III (the "Trust") is an open-end
investment company registered under the Investment Company Act of 1940, as
amended. The Trust comprises the Nuveen Flagship Alabama Municipal Bond Fund
(the "Fund"), among others. The Trust was organized as a Massachusetts business
trust on July 1, 1996.
 
     The John Nuveen Company ("Nuveen"), parent of John Nuveen & Co.
Incorporated and Nuveen Advisory Corp., respectively, the distributor
("Distributor") and investment advisor ("Adviser") of the Fund, entered into an
agreement under which Nuveen acquired Flagship Resources Inc. and after the
close of business on January 31, 1997, consolidated their respective mutual fund
businesses. This agreement was approved at a meeting by the shareholders of the
Flagship Funds in December 1996.
 
     After the close of business on January 31, 1997, Flagship Alabama Double
Tax Exempt Fund ("Flagship Alabama") was reorganized into the Trust and renamed
Nuveen Flagship Alabama Municipal Bond Fund ("Nuveen Flagship Alabama"). Prior
to the reorganization, Flagship Alabama was a sub-trust of the Flagship Tax
Exempt Funds Trust.
 
     The Fund seeks to provide high tax-free income and preservation of capital
through investments in a diversified portfolio of quality municipal bonds.
 
     The following is a summary of significant accounting policies followed by
the Fund in the preparation of its financial statements in accordance with
generally accepted accounting principles.
 
  Securities Valuation
 
     The prices of municipal bonds in the Fund's investment portfolio are
provided by a pricing service approved by the Fund's Board of Trustees. When
price quotes are not readily available (which is usually the case for municipal
securities), the pricing service establishes fair market value based on yields
or prices of municipal bonds of comparable quality, type of issue, coupon,
maturity and rating, indications of value from securities dealers and general
market conditions. Temporary investments in securities that have variable rate
and demand features qualifying them as short-term securities are valued at
amortized cost, which approximates market value.
 
  Securities Transactions
 
     Securities transactions are recorded on a trade date basis. Realized gains
and losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Fund has instructed the custodian to
segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
November 30, 1997, the Fund had an outstanding when-issued purchase commitment
of $288,418.
 
  Interest Income
 
     Interest income is determined on the basis of interest accrued, adjusted
for amortization of premiums and accretion of discounts on long-term debt
securities when required for federal income tax purposes.
 
  Dividends and Distributions to Shareholders
 
     Tax-exempt net investment income is declared as a dividend monthly and
payment is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryforwards.
 
     Distributions to shareholders of tax-exempt net investment income, net
realized capital gains and/or market discount are recorded on the ex-dividend
date. The amount and timing of distributions are determined in accordance with
federal income tax regulations, which may differ from generally accepted
accounting principles. Accordingly, temporary over-distributions as a result of
these differences may occur and will be classified as either distributions in

excess of net investment income, distributions in excess of net realized gains
and/or distributions in excess of net ordinary taxable income from investment
transactions, where applicable.
 
  Income Taxes
 
     The Fund is a separate taxpayer for federal income tax purposes. The Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Fund
currently considers significant net realized capital gains and/or market
discount as amounts in excess of $.001 per share. Furthermore, the Fund intends
to satisfy conditions which will enable interest from municipal securities,
which is exempt from regular federal and Alabama state income taxes, to retain
such tax-exempt status when distributed to the shareholders of the Fund. Net
realized capital gain and market discount distributions are subject to federal
taxation.
 
  Flexible Sales Charge Program
 
     The Fund offers Class A, B, C and R Shares. Class A Shares are sold with a
sales charge and incur an annual 12b-1 service fee. Class A Share purchases of
$1 million or more are sold at net asset value without an up-front sales charge
but may be subject to a 1% contingent deferred sales charge ("CDSC") if redeemed
within 18 months of purchase. Class B Shares are sold without a sales charge but
incur annual 12b-1 distribution and service fees. An investor purchasing Class B
Shares agrees to pay a CDSC of up to 5% depending upon the length of time the
shares are held by the investor (CDSC is reduced to 0% at the end of six years).
Class B Shares convert to Class A Shares eight years after purchase. Class C
Shares are sold without a sales charge but incur annual 12b-1 distribution and
service fees. An investor purchasing Class C Shares agrees to pay a CDSC of 1%
if Class C Shares are redeemed within one year of purchase. Class R Shares are
not subject to any sales charge or 12b-1 distribution or service fees. Class R
Shares are available for purchases of over $1 million and in other limited
circumstances.
 
  Derivative Financial Instruments
 
     The Fund may invest in certain derivative financial instruments including
futures, forward, swap, option contracts, and other financial instruments with
similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the six months ended November 30, 1997.
 
  Expense Allocation
 
     Expenses of the Fund that are not directly attributable to a specific class
of shares are prorated among the classes based on the relative net assets of
each class. Expenses directly attributable to a class of shares, which presently
only includes 12b-1 distribution and service fees, are recorded to the specific
class.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period.
 
  Organizational Expenses
 
     The organizational expenses incurred on behalf of the Fund (approximately
$60,800) will be reimbursed to the Adviser on a straight-line basis over a
period of three years. As of November 30, 1997, $30,430 has been reimbursed.

6. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES
 
     Under the Trust's investment management agreement with the Adviser, the
Fund pays an annual management fee, payable monthly, at the rates set forth
below which are based upon the average daily net asset value of the Fund:
 
<TABLE>
<CAPTION>
               AVERAGE DAILY NET ASSET VALUE                  MANAGEMENT FEE

For the first $125 million..................................    .5500 of 1%
For the next $125 million...................................    .5375 of 1
For the next $250 million...................................    .5250 of 1
For the next $500 million...................................    .5125 of 1
For the next $1 billion.....................................    .5000 of 1
For net assets over $2 billion..............................    .4750 of 1
</TABLE>
 
     The management fee compensates the Adviser for overall investment advisory
and administrative services, and general office facilities. The Trust pays no
compensation directly to its Trustees who are affiliated with the Adviser or to
its officers, all of whom receive remuneration for their services to the Trust
from the Adviser.
 
     The Adviser may voluntarily reimburse expenses from time to time, which may
be terminated at any time at its discretion.
 
     During the six months ended November 30, 1997, the Distributor collected
sales charges on purchases of Class A Shares of approximately $18,200 of which
approximately $15,900 were paid out as concessions to authorized dealers. The
Distributor also received 12b-1 service fees on Class A Shares, substantially
all of which were paid to compensate authorized dealers for providing services
to shareholders relating to their investments.
 
     During the six months ended November 30, 1997, the Distributor compensated
authorized dealers directly with approximately $15,500 in commission advances at
the time of purchase. To compensate for commissions advanced to authorized
dealers, all 12b-1 service fees collected on Class B Shares during the first
year following a purchase, all 12b-1 distribution fees on Class B Shares, and
all 12b-1 service and distribution fees on Class C Shares during the first year
following a purchase are retained by the Distributor. During the six months
ended November 30, 1997, the Distributor retained approximately $6,700 in such
12b-1 fees. The remaining 12b-1 fees charged to the Fund were paid to compensate
authorized dealers for providing services to shareholders relating to their
investments.

                         NOTES TO FINANCIAL STATEMENTS
 
                                  MAY 31, 1997
 
1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES
 
     The Nuveen Flagship Multistate Trust III (the "Trust") is an open-end
investment company registered under the Investment Company Act of 1940, as
amended. The Trust comprises Nuveen Flagship Alabama Municipal Bond Fund (the
"Fund"), among others. The Trust was organized as a Massachusetts business trust
on July 1, 1996.
 
     The John Nuveen Company, parent of John Nuveen & Co. Incorporated and
Nuveen Advisory Corp., respectively, the distributor ("Distributor") and
investment advisor ("Adviser") of the Fund, entered into an agreement under
which Nuveen acquired Flagship Resources Inc. and after the close of business on
January 31, 1997, consolidated their respective mutual fund businesses. This
agreement was approved at a meeting by the shareholders of the Flagship Funds in
December 1996.
 
     After the close of business on January 31, 1997, Flagship Alabama Double
Tax Exempt Fund ("Flagship Alabama") was reorganized into the Trust and renamed
Nuveen Flagship Alabama Municipal Bond Fund ("Nuveen Flagship Alabama").
 
     The Fund seeks to provide high tax-free income and preservation of capital
through investments in a diversified portfolio of quality municipal bonds.
 
     The following is a summary of significant accounting policies followed by
the Fund in the preparation of its financial statements in accordance with
generally accepted accounting principles.
 
  Securities Valuation
 
     The prices of municipal bonds in the Fund's investment portfolio are
provided by a pricing service approved by the Fund's Board of Trustees. When
price quotes are not readily available (which is usually the case for municipal
securities), the pricing service establishes fair market value based on yields
or prices of municipal bonds of comparable quality, type of issue, coupon,
maturity and rating, indications of value from securities dealers and general
market conditions. Temporary investments in securities that have variable rate
and demand features qualifying them as short-term securities are valued at
amortized cost, which approximates market value.
 
  Securities Transactions
 
     Securities transactions are recorded on a trade date basis. Realized gains
and losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Fund has instructed the custodian to
segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At May
31, 1997, the Fund had a when-issued purchase commitment of $197,219.
 
  Interest Income
 
     Interest income is determined on the basis of interest accrued, adjusted
for amortization of premiums and accretion of discounts on long-term debt
securities as required for federal income tax purposes.
 
  Dividends and Distributions to Shareholders
 
     Tax-exempt net investment income is declared as a dividend monthly and
payment is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryovers. Prior to the
reorganization, tax-exempt net investment income for Flagship Alabama was
declared as a dividend daily and payment was made on the last business day of
each month.
 
     Distributions to shareholders of tax-exempt net investment income, net
realized capital gains and/or market discount are recorded on the ex-dividend
date. The amount and timing of distributions are determined in accordance with
federal income tax regulations, which may differ from generally accepted
accounting principles. Accordingly, temporary over-distributions as a result of
these differences may occur and will be classified as either distributions in
 
                                      E-16

excess of net investment income, distributions in excess of net realized gains
and/or distributions in excess of net ordinary taxable income from investment
transactions, where applicable.
 
  Income Taxes
 
     The Fund is a separate taxpayer for federal income tax purposes. The Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Fund
currently considers significant net realized capital gains and/or market
discount as amounts in excess of $.001 per share. Furthermore, the Fund intends
to satisfy conditions which will enable interest from municipal securities,
which is exempt from regular federal and Alabama state income taxes, to retain
such tax-exempt status when distributed to the shareholders of the Fund. All
income dividends paid during the fiscal year ended May 31, 1997, have been
designated Exempt Interest Dividends. Net realized capital gain and market
discount distributions are subject to federal taxation.
 
  Flexible Sales Charge Program
 
     The Fund offers Class A, B, C and R Shares. Class B, C and R Shares were
first offered for sale on February 1, 1997. Class A Shares are sold with a sales
charge and incur an annual 12b-1 service fee. Class B Shares are sold without a
sales charge but incur annual 12b-1 distribution and service fees. An investor
purchasing Class B Shares agrees to pay a contingent deferred sales charge
("CDSC") of up to 5% depending upon the length of time the shares are held by
the investor (CDSC is reduced to 0% at the end of six years). Class C Shares are
sold without a sales charge but incur annual 12-1 distribution and service fees.
An investor purchasing Class C Shares agrees to pay a CDSC of 1% if Class C
Shares are redeemed within 12 months of purchase. Class R Shares are not subject
to any sales charge or 12b-1 distribution or service fees. Class R Shares are
available for purchases of over $1 million and in other limited circumstances.
 
  Derivative Financial Instruments
 
     The Fund may invest in certain derivative financial instruments including
futures, forward, swap, and option contracts, and other financial instruments
with similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the fiscal year ended May 31, 1997.
 
  Expense Allocation
 
     Expenses of the Fund that are not directly attributable to a specific class
of shares are prorated among the classes based on the relative net assets of
each class. Expenses directly attributable to a class of shares, which presently
only includes 12b-1 distribution and service fees, are recorded to the specific
class.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period.
 
  Organizational Expenses
 
     The organizational expenses incurred on behalf of the Fund (approximately
$60,800) will be reimbursed to the Adviser on a straight-line basis over a
period of three years. As of May 31, 1997, $20,264 has been reimbursed. In the
event that the Adviser's current investment in the Trust falls below $100,000
prior to the full reimbursement of the organizational expenses, then it will
forego any further reimbursement.

6. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES

below which are based upon the average daily net asset value of the Fund as
follows:
 
<TABLE>

For the first $125 million..................................  .5500 of 1%
For the next $125 million...................................  .5375 of 1
For the next $250 million...................................  .5250 of 1
For the next $500 million...................................  .5125 of 1
For the next $1 billion.....................................  .5000 of 1
For net assets over $2 billion..............................  .4750 of 1
</TABLE>
 
     Prior to the reorganization (see note 1) Flagship Alabama paid a management
fee of .5 of 1%. The management fee compensates the Adviser for overall
investment advisory and administrative services, and general office facilities.
The Trust pays no compensation directly to its Trustees who are affiliated with
the Adviser or to its officers, all of whom receive remuneration for their
services to the Trust from the Adviser.
 
     The Adviser may voluntarily reimburse expenses from time to time, which may
be terminated at any time at its discretion.
 
     During the fiscal year ended May 31, 1997, the Distributor and its
predecessor (Flagship Funds Inc., a wholly-owned subsidiary of Flagship
Resources Inc.) collected gross sales charges on purchases of Class A Shares of
approximately $51,400 of which approximately $44,500 were paid out as
concessions to authorized dealers. The distributor and its predecessor also
received 12b-1 service fees on Class A Shares, approximately one-half of which
was paid to compensate authorized dealers for providing services to shareholders
relating to their investments.
 
     During the fiscal year ended May 31, 1997, the Distributor and its
predecessor compensated authorized dealers directly with approximately $25,600
in commission advances at the time of purchase. To compensate for commissions
advanced to authorized dealers, all 12b-1 service fees collected on Class B
Shares during the first year following a purchase, all 12b-1 distribution fees
collected on Class B Shares, and all 12b-1 service and distribution fees on
Class C Shares during the first year following a purchase are retained by the
Distributor. The remaining 12b-1 fees charged to the Fund were paid to
compensate authorized dealers for providing services to shareholders relating to
their investments.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Trustees and Shareholders of
Nuveen Flagship Alabama Municipal Bond Fund:
 
     We have audited the accompanying statement of net assets of Nuveen Flagship
Alabama Municipal Bond Fund, including the portfolio of investments, as of May
31, 1997, the related statement of operations for the period then ended and the
statement of changes in net assets, and the financial highlights for each of the
periods presented. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of May
31, 1997, by correspondence with the Fund's custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by management as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
     In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of the Nuveen Flagship
Alabama Municipal Bond Fund at May 31, 1997, the results of its operations, the
changes in its net assets and the financial highlights for the respective stated
periods, in conformity with generally accepted accounting principles.

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
                               NOVEMBER 30, 1997
 
1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES
 
     The Nuveen Flagship Multistate Trust III (the "Trust") is an open-end
investment company registered under the Investment Company Act of 1940, as
amended. The Trust comprises the Nuveen Flagship South Carolina Municipal Bond
Fund (the "Fund"), among others. The Trust was organized as a Massachusetts
business trust on July 1, 1996.
 
     The John Nuveen Company ("Nuveen"), parent of John Nuveen & Co.
Incorporated and Nuveen Advisory Corp., respectively, the distributor
("Distributor") and investment advisor ("Adviser") of the Fund, entered into an
agreement under which Nuveen acquired Flagship Resources Inc. and after the
close of business on January 31, 1997, consolidated their respective mutual fund
businesses. This agreement was approved at a meeting by the shareholders of the
Flagship Funds in December 1996.
 
     After the close of business on January 31, 1997, Flagship South Carolina
Double Tax Exempt Fund ("Flagship South Carolina") was reorganized into the
Trust and renamed Nuveen Flagship South Carolina Municipal Bond Fund ("Nuveen
Flagship South Carolina"). Prior to the reorganization, Flagship South Carolina
was a sub-trust of the Flagship Tax Exempt Funds Trust.
 
     The Fund seeks to provide high tax-free income and preservation of capital
through investments in a diversified portfolio of quality municipal bonds.
 
     The following is a summary of significant accounting policies followed by
the Fund in the preparation of its financial statements in accordance with
generally accepted accounting principles.
 
  Securities Valuation
 
     The prices of municipal bonds in the Fund's investment portfolio are
provided by a pricing service approved by the Fund's Board of Trustees. When
price quotes are not readily available (which is usually the case for municipal
securities), the pricing service establishes fair market value based on yields
or prices of municipal bonds of comparable quality, type of issue, coupon,
maturity and rating, indications of value from securities dealers and general
market conditions. Temporary investments in securities that have variable rate
and demand features qualifying them as short-term securities are valued at
amortized cost, which approximates market value.
 
  Securities Transactions
 
     Securities transactions are recorded on a trade date basis. Realized gains
and losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Fund has instructed the custodian to
segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
November 30, 1997, the Fund had no such outstanding purchase commitments.
 
  Interest Income
 
     Interest income is determined on the basis of interest accrued, adjusted
for amortization of premiums and accretion of discounts on long-term debt
securities when required for federal income tax purposes.
 
  Dividends and Distributions to Shareholders
 
     Tax-exempt net investment income is declared as a dividend monthly and
payment is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryforwards.
 
     Distributions to shareholders of tax-exempt net investment income, net
realized capital gains and/or market discount are recorded on the ex-dividend
date. The amount and timing of distributions are determined in accordance with
federal income tax regulations, which may differ from generally accepted
accounting principles. Accordingly, temporary over-distributions as a result of
these differences may occur and will be classified as either distributions in

excess of net investment income, distributions in excess of net realized gains
and/or distributions in excess of net ordinary taxable income from investment
transactions, where applicable.
 
  Income Taxes
 
     The Fund is a separate taxpayer for federal income tax purposes. The Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Fund
currently considers significant net realized capital gains and/or market
discount as amounts in excess of $.001 per share. Furthermore, the Fund intends
to satisfy conditions which will enable interest from municipal securities,
which is exempt from regular federal and South Carolina state income taxes, to
retain such tax-exempt status when distributed to the shareholders of the Fund.
Net realized capital gain and market discount distributions are subject to
federal taxation.
 
  Flexible Sales Charge Program
 
     The Fund offers Class A, B, C and R Shares. Class A Shares are sold with a
sales charge and incur an annual 12b-1 service fee. Class A Share purchases of
$1 million or more are sold at net asset value without an up-front sales charge
but may be subject to a 1% contingent deferred sales charge ("CDSC") if redeemed
within 18 months of purchase. Class B Shares are sold without a sales charge but
incur annual 12b-1 distribution and service fees. An investor purchasing Class B
Shares agrees to pay a CDSC of up to 5% depending upon the length of time the
shares are held by the investor (CDSC is reduced to 0% at the end of six years).
Class B Shares convert to Class A Shares eight years after purchase. Class C
Shares are sold without a sales charge but incur annual 12b-1 distribution and
service fees. An investor purchasing Class C Shares agrees to pay a CDSC of 1%
if Class C Shares are redeemed within one year of purchase. Class R Shares are
not subject to any sales charge or 12b-1 distribution or service fees. Class R
Shares are available for purchases of over $1 million and in other limited
circumstances.
 
  Derivative Financial Instruments
 
     The Fund may invest in certain derivative financial instruments including
futures, forward, swap, option contracts, and other financial instruments with
similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the six months ended November 30, 1997.
 
  Expense Allocation
 
     Expenses of the Fund that are not directly attributable to a specific class
of shares are prorated among the classes based on the relative net assets of
each class. Expenses directly attributable to a class of shares, which presently
only includes 12b-1 distribution and service fees, are recorded to the specific
class.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period.
 
  Organizational Expenses
 
     The organizational expenses incurred on behalf of the Fund (approximately
$35,400) will be reimbursed to the Adviser on a straight-line basis over a
period of three years. As of November 30, 1997, $17,747 has been reimbursed.

be terminated at any time at its discretion.

sales charges on purchases of Class A Shares of approximately $33,400 of which

all of which were paid to compensate authorized dealers for providing services
to shareholders relating to their investments.
 
     During the six months ended November 30, 1997, the Distributor compensated

                         NOTES TO FINANCIAL STATEMENTS
 
                                  MAY 31, 1997
 
1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES
 
     The Nuveen Flagship Multistate Trust III (the "Trust") is an open-end
investment company registered under the Investment Company Act of 1940, as
amended. The Trust comprises Nuveen Flagship South Carolina Municipal Bond Fund
(the "Fund"), among others. The Trust was organized as a Massachusetts business
trust on July 1, 1996.
 
     The John Nuveen Company, parent of John Nuveen & Co. Incorporated and
Nuveen Advisory Corp., respectively, the distributor ("Distributor") and
investment advisor ("Adviser") of the Fund, entered into an agreement under
which Nuveen acquired Flagship Resources Inc. and after the close of business on
January 31, 1997, consolidated their respective mutual fund businesses. This
agreement was approved at a meeting by the shareholders of the Flagship Funds in
December 1996.
 
     After the close of business on January 31, 1997, Flagship South Carolina
Double Tax Exempt Fund ("Flagship South Carolina") was reorganized into the
Trust and renamed Nuveen Flagship South Carolina Municipal Bond Fund ("Nuveen
Flagship South Carolina").
 
     The Fund seeks to provide high tax-free income and preservation of capital
through investments in a diversified portfolio of quality municipal bonds.
 
     The following is a summary of significant accounting policies followed by
the Fund in the preparation of its financial statements in accordance with
generally accepted accounting principles.
 
  Securities Valuation
 
     The prices of municipal bonds in the Fund's investment portfolio are
provided by a pricing service approved by the Fund's Board of Trustees. When
price quotes are not readily available (which is usually the case for municipal
securities), the pricing service establishes fair market value based on yields
or prices of municipal bonds of comparable quality, type of issue, coupon,
maturity and rating, indications of value from securities dealers and general
market conditions. Temporary investments in securities that have variable rate
and demand features qualifying them as short-term securities are valued at
amortized cost, which approximates market value.
 
  Securities Transactions
 
     Securities transactions are recorded on a trade date basis. Realized gains
and losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. Any securities so purchased are subject to
market fluctuation during this period. The Fund has instructed the custodian to
segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At May
31, 1997, the Fund had no such purchase commitments.
 
  Interest Income
 
     Interest income is determined on the basis of interest accrued, adjusted
for amortization of premiums and accretion of discounts on long-term debt
securities when required for federal income tax purposes.
 
  Dividends and Distributions to Shareholders
 
     Tax-exempt net investment income is declared as a dividend monthly and
payment is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryovers. Prior to the
reorganization, tax-exempt net investment income for Flagship South Carolina was
declared as a dividend daily and payment was made on the last business day of
each month.
 
     Distributions to shareholders of tax-exempt net investment income, net
realized capital gains and/or market discount are recorded on the ex-dividend
date. The amount and timing of distributions are determined in accordance with
federal income tax regulations, which may differ from generally accepted
accounting principles. Accordingly, temporary over-distributions as a result of
these differences may occur and will be classified as either distributions in
 
                                      F-16

excess of net investment income, distributions in excess of net realized gains
and/or distributions in excess of net ordinary taxable income from investment
transactions, where applicable.
 
  Income Taxes
 
     The Fund is a separate taxpayer for federal income tax purposes. The Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount from investment transactions. The Fund
currently considers significant net realized capital gains and/or market
discount as amounts in excess of $.001 per share. Furthermore, the Fund intends
to satisfy conditions which will enable interest from municipal securities,
which is exempt from regular federal and South Carolina state income taxes, to
retain such tax-exempt status when distributed to the shareholders of the Fund.
All income dividends paid during the fiscal year ended May 31, 1997, have been
designated Exempt Interest Dividends. Net realized capital gains and market
discount distributions are subject to federal taxation.
 
  Flexible Sales Charge Program
 
     The Fund offers Class A, B, C and R Shares. Class B, C and R Shares were
first offered for sale on February 1, 1997. Class A Shares are sold with a sales
charge and incur an annual 12b-1 service fee. Class B Shares are sold without a
sales charge but incur annual 12b-1 distribution and service fees. An investor
purchasing Class B Shares agrees to pay a contingent deferred sales charge
("CDSC") of up to 5% depending upon the length of time the shares are held by
the investor (CDSC is reduced to 0% at the end of six years). Class C Shares are
sold without a sales charge but incur annual 12b-1 distribution and service
fees. An investor purchasing Class C Shares agrees to pay a CDSC of 1% if Class
C Shares are redeemed within 12 months of purchase. Class R Shares, are not
subject to any sales charge or 12b-1 distribution or service fees. Class R
Shares are available for purchases of over $1 million and in other limited
circumstances.
 
  Derivative Financial Instruments
 
     The Fund may invest in certain derivative financial instruments including
futures, forward, swap, and option contracts, and other financial instruments
with similar characteristics. Although the Fund is authorized to invest in such
financial instruments, and may do so in the future, it did not make any such
investments during the fiscal year ended May 31, 1997.
 
  Expense Allocation
 
     Expenses of the Fund that are not directly attributable to a specific class
of shares are prorated among the classes based on the relative net assets of
each class. Expenses directly attributable to a class of shares, which presently
only includes 12b-1 distribution and service fees, are recorded to the specific
class.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of increases and
decreases in net assets from operations during the reporting period.
 
  Organizational Expenses
 
     The organizational expenses incurred on behalf of the Fund (approximately
$35,400) will be reimbursed to the Adviser on a straight-line basis over a
period of three years beginning June 1, 1996. As of May 31, 1997, $11,818 has
been reimbursed. In the event that the Adviser's current investment in the Trust
falls below $100,000 prior to the full reimbursement of the organizational
expenses, then it will forego any further reimbursement.

follows:

For the next $125 million...................................  .5375 of 1
For the next $250 million...................................  .5250 of 1
For the next $500 million...................................  .5125 of 1
For the next $1 billion.....................................  .5000 of 1
For net assets over $2 billion..............................  .4750 of 1
</TABLE>
 
     Prior to the reorganization (see note 1) Flagship South Carolina paid a
management fee of .5 of 1%. The management fee compensates the Adviser for
overall investment advisory and administrative services, and general office
facilities. The Trust pays no compensation directly to its Trustees who are
affiliated with the Adviser or to its officers, all of whom receive remuneration
for their services to the Trust from the Adviser.
 
     The Adviser may voluntarily reimburse expenses from time to time, which may
be terminated at any time at its discretion.
 
     During the fiscal year ended May 31, 1997, the Distributor and its
predecessor (Flagship Funds Inc., a wholly-owned subsidiary of Flagship
Resources Inc.) collected gross sales charges on purchases of Class A Shares of
approximately $49,200 of which approximately $42,900 were paid out as
concessions to authorized dealers. The Distributor and its predecessor also
received 12b-1 service fees on Class A Shares approximately one-half of which
was paid to compensate authorized dealers for providing services to shareholders
relating to their investments.
 
     During the fiscal year ended May 31, 1997, the Distributor and its
predecessor compensated authorized dealers directly with approximately $11,000
in commission advances at the time of purchase. To compensate for commissions
advanced to authorized dealers, all 12b-1 service fees collected on Class B
Shares during the first year following a purchase, all 12b-1 distribution fees
collected on Class B Shares, and all 12b-1 service and distribution fees on
Class C Shares during the first year following a purchase are retained by the
Distributor. The remaining 12b-1 fees charged to the Fund were paid to
compensate authorized dealers for providing services to shareholders relating to
their investments. The Distributor and its predecessor also collected and
retained approximately $200 of CDSC on share redemptions during the fiscal year
ended May 31, 1997.
 
7. COMPOSITION OF NET ASSETS

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Trustees and Shareholders of
Nuveen Flagship South Carolina Municipal Bond Fund:
 
     We have audited the accompanying statement of net assets of Nuveen Flagship
South Carolina Municipal Bond Fund, including the portfolio of investments, as
of May 31, 1997, the related statement of operations for the period then ended
and the statement of changes in net assets, and the financial highlights for
each of the periods presented. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of May
31, 1997, by correspondence with the Fund's custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of the Nuveen Flagship
South Carolina Municipal Bond Fund at May 31, 1997, the results of its
operations, the changes in its net assets and the financial highlights for the
respective stated periods, in conformity with generally accepted accounting
principles.

                          PART C -- OTHER INFORMATION
 
ITEM 15.  INDEMNIFICATION
 
     Section 4 of Article XII of Registrant's Declaration of Trust provides as
follows:
 
     Subject to the exceptions and limitations contained in this Section 4,
every person who is, or has been, a Trustee, officer, employee or agent of the
Trust, including persons who serve at the request of the Trust as directors,
trustees, officers, employees or agents of another organization in which the
Trust has an interest as a shareholder, creditor or otherwise (hereinafter
referred to as a "Covered Person"), shall be indemnified by the Trust to the
fullest extent permitted by law against liability and against all expenses
reasonably incurred or paid by him in connection with any claim, action, suit,
or proceeding in which he becomes involved as a party or otherwise by virtue of
his being or having been such a Trustee, director, officer, employee or agent
and against amounts paid or incurred by him in settlement thereof.
 
     No indemnification shall be provided hereunder to a Covered Person:
 
          (a) against any liability to the Trust or its Shareholders by reason
     of a final adjudication by the court or other body before which the
     proceeding was brought that he engaged in willful misfeasance, bad faith,
     gross negligence or reckless disregard of the duties involved in the
     conduct of his office;
 
          (b) with respect to any matter as to which he shall have been finally
     adjudicated not to have acted in good faith in the reasonable belief that
     his action was in the best interests of the Trust; or
 
          (c) in the event of a settlement or other disposition not involving a
     final adjudication (as provided in paragraph (a) or (b)) and resulting in a
     payment by a Covered Person, unless there has been either a determination
     that such Covered Person did not engage in willful misfeasance, bad faith,
     gross negligence or reckless disregard of the duties involved in the
     conduct of his office by the court or other body approving the settlement
     or other disposition or a reasonable determination, based on a review of
     readily available facts (as opposed to a full trial-type inquiry), that he
     did not engage in such conduct:
 
             (i) by a vote of a majority of the Disinterested Trustees acting on
        the matter (provided that a majority of the Disinterested Trustees then
        in office act on the matter); or
 
             (ii) by written opinion of independent legal counsel.
 
     The rights of indemnification herein provided may be insured against by
policies maintained by the Trust, shall be severable, shall not affect any other
rights to which any Covered Person may now or hereafter be entitled, shall
continue as to a person who has ceased to be such a Covered Person and shall
inure to the benefit of the heirs, executors and administrators of such a
person. Nothing contained herein shall affect any rights to indemnification to
which Trust personnel other than Covered Persons may be entitled by contract or
otherwise under law.
 
     Expenses of preparation and presentation of a defense to any claim, action,
suit or proceeding subject to a claim for indemnification under this Section 4
shall be advanced by the Trust prior to final disposition thereof upon receipt
of an undertaking by or on behalf of the recipient to repay such amount if it is
ultimately determined that he is not entitled to indemnification under this
Section 4, provided that either:
 
          (a) such undertaking is secured by a surety bond or some other
     appropriate security or the Trust shall be insured against losses arising
     out of any such advances; or
 
          (b) a majority of the Disinterested Trustees acting on the matter
     (provided that a majority of the Disinterested Trustees then in office act
     on the matter) or independent legal counsel in a written opinion shall
     determine, based upon a review of the readily available facts (as opposed
     to a full trial-type inquiry), that there is reason to believe that the
     recipient ultimately will be found entitled to indemnification.
 
     As used in this Section 4, a "Disinterested Trustee" is one (x) who is not
an Interested Person of the Trust (including, as such Disinterested Trustee,
anyone who has been exempted from being an Interested Person by any rule,
regulation or order of the Commission), and (y) against whom none of such
actions, suits or other proceedings or another action, suit or other proceeding
on the same or similar grounds is then or has been pending.
 
     As used in this Section 4, the words "claim," "action," "suit" or
"proceeding" shall apply to all claims, actions, suits, proceedings (civil,
criminal, administrative or other, including appeals), actual or threatened; and
the word "liability" and "expenses" shall include without limitation, attorneys'
fees, costs, judgments, amounts paid in settlement, fines, penalties and other
liabilities.
 
                                       C-1
<PAGE>   308
 
     The trustees and officers of the Registrant are covered by an Investment
Trust Errors and Omission policy in the aggregate amount of $20,000,000 (with a
maximum deductible of $500,000) against liability and expenses of claims of
wrongful acts arising out of their position with the Registrant, except for
matters which involved willful acts, bad faith, gross negligence and willful
disregard of duty (i.e., where the insured did not act in good faith for a
purpose he or she reasonably believed to be in the best interest of Registrant
or where he or she shall have had reasonable cause to believe this conduct was
unlawful).
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to the officers, trustees or controlling persons of the
Registrant pursuant to the Declaration of Trust of the Registrant or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by an officer or trustee or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such officer, trustee or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question of whether such
indemnification by it is against policy as expressed in the Act and will be
governed by the final adjudication of such issue.

         Re:      NUVEEN FLAGSHIP MUNICIPAL TRUST
                  REGISTRATION STATEMENT ON FORM N-14
                  NUVEEN FLAGSHIP ALL-AMERICAN MUNICIPAL BOND FUND


Ladies and Gentlemen:

         We are acting as counsel for Nuveen Flagship Municipal Trust, a
Massachusetts business trust (the "Trust"), in connection with the Trust's
filing of a registration statement on Form N-14 (the "Registration Statement")
with the Securities and Exchange Commission covering the registration of shares
of beneficial interest, $.01 par value per share, (the "Shares") of the Trust
designated Nuveen Flagship All-American Municipal Bond Fund, pursuant to the
proposed reorganization by and between the Nuveen Flagship Multistate Trust III
(an "Acquired Fund Trust"), a Massachusetts business trust, on behalf of its
series of shares designated Nuveen Flagship Alabama Municipal Bond Fund and
Nuveen South Carolina Municipal Bond Fund, as described in the Registration
Statement and pursuant to that certain Agreement and Plan of Reorganization
entered into between the Trust and the Acquired Trust as of April 25, 1998 (the
"Agreement").

         In that capacity, we have examined such business trust records,
certificates and other documents, and have made such other factual and legal
investigations as we have deemed necessary and appropriate for the purposes of
this opinion. In such examination, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, the
conformity to originals of all documents submitted to us as certified copies or
photocopies and the authenticity of the originals of such latter documents.
Insofar as this opinion pertains to matters governed by the laws of the
Commonwealth of Massachusetts, we are relying, with your consent, upon the
opinion of Bingham Dana LLP dated May 22, 1998, which opinion is satisfactory 
in substance and form to us.

         Based upon the foregoing, it is our opinion that:

         (1)      The Trust is a Massachusetts business trust duly organized and
                  existing under the laws of the Commonwealth of Massachusetts.

         (2)      The Shares, when issued and sold in accordance with the
                  Trust's Declaration of Trust, all amendments thereto, and
                  By-Laws and for the consideration described in the Agreement,
                  will be legally issued, fully paid and non-assessable, except
                  that, as set forth in the Registration Statement, shareholders
                  of the Trust may under certain circumstances be held
                  personally liable for its obligations.

         We hereby consent to the filing of this opinion as Exhibit 11(a) to the
Registration Statement and to the references to us under the caption "Legal
Opinions" in the Joint Proxy Statement Prospectus contained in the Registration
Statement.

         Re:      Nuveen Flagship Municipal Trust/Nuveen Flagship All-American
                           Municipal Bond Fund

Ladies and Gentlemen:

         We have acted as special Massachusetts counsel to Nuveen Flagship
Municipal Trust, a Massachusetts business trust (the "Trust"), in connection
with the Trust's Registration Statement on Form N-14 to be filed with the
Securities and Exchange Commission on or about May 22, 1998 (the "Registration
Statement"), with respect to the shares of beneficial interest, par value $.01
per share (the "Shares") of its series Nuveen Flagship All-American Municipal
Bond Fund (the "Acquiring Fund") to be issued in exchange for substantially all
of the assets of Nuveen Flagship Alabama Municipal Bond Fund and Nuveen Flagship
South Carolina Municipal Bond Fund, each a series of Nuveen Flagship Multistate
Trust III, a Massachusetts business trust (each, an "Acquired Fund"), as
described in the Registration Statement. You have requested that we deliver this
opinion to you, as special counsel to the Trust, for use by you in connection
with your opinion to the Trust with respect to the Shares.

         In connection with the furnishing of this opinion, we have examined the
following documents:

                  (a) a certificate of the Secretary of State of the 
         Commonwealth of Massachusetts as to the existence of the Trust;

                  (b) a copy, as filed with the Secretary of State of the
         Commonwealth of Massachusetts on July 1, 1996, of the Trust's
         Declaration of Trust (the "Declaration");

                  (c) a copy of the Trust's Amended and Restated Establishment
         and Designation of Series dated October 9, 1996 (the "Designation of
         Series");

                  (d) a copy of the Trust's Establishment and Designation of
         Classes dated July 10, 1996 (the "Designation of Classes");

                  (e) a certificate executed by an appropriate officer of the
         Trust, certifying as to, and attaching copies of, the Trust's
         Declaration, Designation of Series, Designation of Classes, By-Laws,
         and certain resolutions adopted by the Trustees of the Trust;

                  (f) a printer's proof dated May 21, 1998 of the 
         Registration Statement; and

                  (g) a copy of the Agreement and Plan of Reorganization entered
         into by the Trust as of April 25, 1998, on behalf of the Acquiring
         Fund, providing for (a) the acquisition by the Acquiring Fund of
         substantially all of the assets of each of the Acquired Funds in
         exchange for the Shares and the Acquiring Fund's assumption of
         substantially all of the liabilities of each of the Acquired Funds and
         (b) the pro rata distribution of the Shares to the holders of the
         shares of the Acquired Funds in liquidation of the Acquired Funds, in
         the form included in the printer's proof referred to in paragraph (f)
         above (the "Agreement and Plan of Reorganization").

         In such examination, we have assumed the genuineness of all signatures,
the conformity to the originals of all of the documents reviewed by us as
copies, including conformed copies, the authenticity and completeness of all
original documents reviewed by us in original or copy form and the legal
competence of each individual executing any document. We have assumed that the
Registration Statement as filed with the Securities and Exchange Commission will
be in substantially the form of the printer's proof referred to in paragraph (f)
above, and that the Agreement and Plan of Reorganization has been duly
completed, executed and delivered by the parties thereto in substantially the
form of the copy referred to in paragraph (g) above.

         This opinion is based entirely on our review of the documents listed
above and such investigation of law as we have deemed necessary or appropriate.
We have made no other review or investigation of any kind whatsoever, and we
have assumed, without independent inquiry, the accuracy of the information set
forth in such documents.

         This opinion is limited solely to the internal substantive laws of the
Commonwealth of Massachusetts as applied by courts located in such Commonwealth,
to the extent the same may apply to or govern the transactions covered by this
opinion, except that we express no opinion as to any Massachusetts securities
law.

         We understand that all of the foregoing assumptions and limitations are
acceptable to you.

         Based upon and subject to the foregoing, please be advised that it is
our opinion that:

         1. The Trust is duly organized and existing under the Trust's
Declaration of Trust and the laws of the Commonwealth of Massachusetts as a
voluntary association with transferable shares of beneficial interest commonly
referred to as a "Massachusetts business trust."

         2. The Shares, when issued and sold in accordance with the Trust's

Acquiring Fund may under certain circumstances be held personally liable for its
obligations.

         We hereby consent to your reliance on this opinion in connection with
your opinion to the Trust with respect to the Shares, to the reference to our
name in the Registration Statement under the heading "Legal Opinions" and to the
filing of this opinion as an exhibit to the Registration Statement.

Gentlemen:

         You have requested our opinion regarding certain federal income tax
consequences of the proposed reorganizations (each a "Reorganization") of Nuveen
Flagship Alabama Municipal Bond Fund ("Acquired Fund I"), a separate portfolio
of Nuveen Flagship Multistate Trust III, a Massachusetts business trust
("Acquired Trust"), and Nuveen Flagship South Carolina Municipal Bond Fund
("Acquired Fund II"), also a separate portfolio of Acquired Trust, (Acquired
Fund I and Acquired Fund II are also each referred to as an "Acquired Fund" and
collectively as the "Acquired Funds") into Nuveen Flagship All-American
Municipal Bond Fund ("Acquiring Fund"), a separate portfolio of Nuveen Flagship
Municipal Trust, a Massachusetts business trust ("Acquiring Trust"). The
Reorganizations contemplate the acquisition by the Acquiring Fund of
substantially all the assets of the Acquired Funds in exchange for voting shares
of beneficial interest ("shares") of the Acquiring Fund and the assumption of
the Acquired Funds' liabilities. Thereafter, the shares of the Acquiring Fund
will be distributed to the shareholders of the Acquired Funds and each Acquired
Fund will be completely liquidated and terminated. The foregoing will be
accomplished pursuant to an Agreement and Plan of Reorganization, dated as of
April 25,

1998 (the "Plan"), entered into by the Acquired Trust, on behalf of the
Acquired Funds, and the Acquiring Trust, on behalf of the Acquiring Fund.

         In rendering this opinion, we have reviewed and relied upon statements
made to us by certain of your officers. We have also examined certificates of
such officers and such other agreements, documents, and corporate records that
have been made available to us and such other matters as we have deemed relevant
for purposes of this opinion. In such examination, we have assumed the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals, the conformity to originals of all documents submitted to us as
copies and the authenticity of the originals of such latter documents.

         Our opinion is based, in part, on the assumption that the proposed
Reorganizations described herein will occur in accordance with the agreements
and the facts and representations set forth or referred to in this opinion
letter, and that such facts and representations are accurate as of the date
hereof and will be accurate on the effective date of such Reorganizations (the
"Effective Time"). As more fully discussed below, we have also assumed in
issuing our opinion that the shareholders of the Acquired Funds do not have any
plan or intention to dispose of a certain number of the Acquiring Fund shares
received by them in the Reorganizations. We have undertaken no independent
investigation of the accuracy of the facts, representations and assumptions set
forth or referred to herein.

         For the purposes indicated above, and based upon the facts, assumptions
and conditions as set forth herein, and the representations made to us by duly
authorized officers on behalf of the Acquired Funds and the Acquiring Fund in a
letter dated May 22, 1998, it is our opinion that:

                  1. The acquisitions by the Acquiring Fund of substantially all
         the assets of the Acquired Funds in exchange solely for Acquiring Fund
         voting shares and the assumption by the Acquiring Fund of the Acquired
         Funds' liabilities, if any, followed by the distribution by the
         Acquired Funds of the Acquiring Fund shares to the shareholders of the
         Acquired Funds in exchange for their Acquired Funds shares in complete
         liquidation of the Acquired Funds, will each constitute a
         "reorganization" within the meaning of Section 368(a)(1)(C) of the
         Internal Revenue Code of 1986, as

         amended (the "Code"), and the Acquiring Fund and, with respect to its
         respective Reorganization, each Acquired Fund will be "a party to a
         reorganization" within the meaning of Section 368(b) of the Code;

                  2. The Acquired Funds' shareholders will recognize no gain or
         loss upon the exchange of all of their Acquired Fund shares for
         Acquiring Fund shares in complete liquidation of an Acquired Fund (Code
         Section 354(a)(1));

                  3. No gain or loss will be recognized by an Acquired Fund upon
         the transfer of substantially all its assets to the Acquiring Fund in
         exchange solely for Acquiring Fund shares and the assumption by the
         Acquiring Fund of such Acquired Fund's liabilities, if any, and with
         respect to the subsequent distribution of those Acquiring Fund shares
         to the Acquired Fund's shareholders in complete liquidation of such
         Acquired Fund (Code Section 361);

                  4. No gain or loss will be recognized by the Acquiring Fund
         upon the acquisition of substantially all the Acquired Funds' assets in
         exchange solely for Acquiring Fund shares and the assumption of the
         Acquired Funds' liabilities, if any (Code Section 1032(a));

                  5. The basis of the assets acquired by the Acquiring Fund will
         be, in each instance, the same as the basis of those assets immediately
         before the transfer when such assets were held by an Acquired Fund, and
         the holding period of such assets acquired by the Acquiring Fund will
         include the holding period thereof when such assets were held by an
         Acquired Fund (Code Sections 362(b) and 1223(2));

                  6. The basis of the Acquiring Fund shares to be received by
         the Acquired Funds' shareholders upon liquidation of the Acquired Funds
         will be, in each instance, the same as the basis of the Acquired Fund
         shares surrendered in exchange therefor (Code Section 358(a)(1)); and

                  7. The holding period of the Acquiring Fund shares to be
         received by the Acquired Funds' shareholders will include the period
         during which the Acquired Fund

         shares to be surrendered in exchange therefor were held, provided such
         Acquired Fund shares were held as capital assets by those shareholders
         on the date of the exchange (Code Section 1223(1)).

                                      FACTS

         Our opinion is based upon the above referenced representations and the
following facts and assumptions, any alteration of which could adversely affect
our conclusions.

         The Acquired Funds have been registered and operated since they
commenced operations as series of open-end, management investment companies
under the Investment Company Act of 1940, 15 U.S.C. Section .80a, et seq. (the 
"1940 Act"). Each Acquired Fund has qualified and will qualify as a regulated
investment company under Section 851 of the Code for each of its taxable years,
and has distributed and will distribute all or substantially all its income so
that it and its shareholders have been and will be taxed in accordance with
Section 852 of the Code.

         The Acquiring Fund is registered, has operated, and will continue to 
operate as a series of an open-end, management investment company under the
1940 Act. It has qualified as a regulated investment company under Section 851
of the Code for each of its taxable years and anticipates so qualifying for all
future years, and has distributed and will distribute all or substantially all
its income so that it and its shareholders will be taxed in accordance with
Section 852 of the Code.

         Upon satisfaction of certain terms and conditions set forth in the Plan
on or before the Effective Time, the following will occur: (a) the Acquiring
Fund will acquire substantially all the assets of the Acquired Funds in exchange
for the Acquiring Fund's assumption of substantially all the liabilities of the
Acquired Funds and the issuance of Acquiring Fund shares to such Acquired Funds;
(b) the Acquiring Fund shares will be distributed to the shareholders of the
Acquired Funds in exchange for their Acquired Fund shares; and (c) the Acquired
Funds will be dissolved and liquidated. The assets of the Acquired Funds to be
acquired by the Acquiring Fund consist primarily of bonds whose interest is
exempt from federal income taxation, cash and other securities held in the
Acquired Funds' portfolios.

         As soon as practicable after the Effective Time, each Acquired Fund
will be liquidated and will distribute the newly issued Acquiring Fund shares it
receives pro rata to its shareholders of record in exchange for such
shareholders' interests in such Acquired Fund. Such liquidation and distribution
will be accomplished by opening accounts on the books of the Acquiring Fund in
the names of the shareholders of each Acquired Fund (on a class by class basis)
and transferring to those shareholder accounts the pro rata number of Acquiring
Fund shares of each respective class as was previously credited to the Acquired
Fund on such books.

         As a result of the Reorganization, every shareholder of each Acquired
Fund will own Acquiring Fund shares that would have an aggregate per share net
asset value immediately after the Effective Time equal to the aggregate per
share net asset value of that shareholder's Acquired Fund shares immediately
prior to the Effective Time. Since the Acquiring Fund shares issued to the
shareholders of the Acquired Funds will be issued at net asset value in exchange
for the net assets of such Acquired Funds having a value equal to the aggregate
per share net asset value of those Acquiring Fund shares so issued, the net
asset value of the Acquiring Fund shares should remain virtually unchanged by
the Reorganization.

         The investment objectives of the Acquiring Fund will be substantially
similar to those of the Acquired Funds and the Acquiring Fund will continue the
historic business of each Acquired Fund or use a significant portion of each
Acquired Fund's historic assets in its business.

         The management of each Acquired Fund has represented to us that, to the
best of their knowledge, there is no current plan or intention on the part of 
any Acquired Fund shareholders to sell, exchange, or otherwise dispose of a
number of Acquiring Fund shares received in the Reorganization that would
reduce the ownership by shareholders of such Acquired Fund to a number of
shares of Acquiring Fund having a value, as of the Effective Time, of less than
50 percent of all the formerly outstanding shares of such Acquired Fund as of
the same time. In issuing our opinion, we have assumed that there is, in fact,
no such plan or intention. If such assumption were inaccurate, it could
adversely affect the opinions contained herein.

         In approving the Reorganizations, the Board of Trustees of the Acquired
Trust identified certain benefits that are likely to result from combining the
funds, including administrative and operating efficiencies, potential for asset
growth, investment performance and greater portfolio diversity. The Board also
considered the possible risks and costs of combining the funds and determined
that the Reorganizations are likely to provide benefits to the shareholders of
each fund that outweigh the costs incurred.


                                   CONCLUSION

         Based on the foregoing, it is our opinion that each acquisition by the
Acquiring Fund, pursuant to the Plan, of substantially all the assets and
liabilities of the Acquired Funds in exchange for voting shares of the Acquiring
Fund will qualify as a reorganization under Code Section 368(a)(1)(C).

         Our opinions set forth above with respect to (1) the nonrecognition of
gain or loss to the Acquired Funds and the Acquiring Fund, (2) the basis and
holding period of the assets received by the Acquiring Fund, (3) the
nonrecognition of gain or loss to the Acquired Funds' shareholders upon the
receipt of the Acquiring Fund shares, and (4) the basis and holding period of
the Acquiring Fund shares received by the Acquired Funds' shareholders, follow
as a matter of law from the opinion that the acquisitions under the Plan will
qualify as reorganizations under Code Section 368(a)(1)(C).

         The opinions expressed in this letter are based on the Code, the Income
Tax Regulations promulgated by the Treasury Department thereunder and judicial
authority reported as of the date hereof. We have also considered the position
of the Internal Revenue Service (the "Service") reflected in published and
private rulings. Although we are not aware of any pending changes to these
authorities that would alter our opinions, there can be no assurances that
future legislative or administrative changes, court decisions or Service
interpretations will not significantly modify the statements or opinions
expressed herein.

         Our opinions are limited to those federal income tax issues
specifically considered herein and are addressed to and are only for the benefit
of the Acquired Funds, the Acquired

opinion as to any other federal income tax issues, or any state or local law
