Prospectus
   
July 1, 1996     
 
Nuveen Municipal Bond Fund (the "Fund") is designed to provide as high a level
of current interest income exempt from regular federal income tax as is
consistent, in the view of the Fund's management, with preservation of capital.
The Fund invests in investment grade quality, long-term Municipal Obligations
judged by the Fund's investment adviser to offer the best values among
Municipal Obligations of similar credit quality.
   
 Each Fund has adopted a Flexible Pricing Program designed to permit you and
your financial adviser to choose the method of purchasing shares that you
believe is most beneficial given the amount of your purchase and any current
holdings of Fund shares, the length of time you expect to hold your investment,
and other relevant circumstances. The Program features three alternative ways
to purchase Fund shares (Classes A, C and R), each with a different combination
of sales charges, ongoing fees, eligibility requirements, and other features.

Expenses."

and Service Plan." Long-term holders of Class C Shares may pay more in Rule
12b-1 distribution fees than the economic equivalent of the maximum front-end
sales charge permitted under the National Association of Securities Dealers
Rules of Fair Practice.     
                    
                 The purpose of the tables above is to help you understand all
                 expenses and fees that you would bear directly or indirectly
                 as a Fund shareholder. The expenses and fees shown are for
                 the fiscal year ended February 29, 1996.

                 EXAMPLE*     
 
                 You would pay the following expenses on a $1,000 investment
                 over various time periods, assuming (1) a 5% annual rate of
                 return and (2) redemption at the end of each time period:

                 *This example does not represent past or future expenses.
                 Actual expenses may be greater or less than those shown.
                 Moreover, the Fund's actual rate of return may be greater or
                 less than the hypothetical 5% return shown in this example.
                 This example assumes that the percentage amounts listed under
                 Annual Operating Expenses remain the same in each of the
                 periods. The ten-year figure for Class C Shares reflects the
                 automatic conversion of Class C Shares into Class A Shares
                 six years after purchase. Based on the foregoing assumptions,
                 the expenses incurred on an investment in Class C Shares will
                 exceed the expenses incurred on an investment in Class A
                 Shares sometime in the sixth year after purchase. You should
                 also note that Class R Shares are available for purchase only
                 under certain limited circumstances, or by specified
                 investors. For additional information about the Fund's fees
                 and expenses, see "Distribution and Service Plan" and
                 "Management of the Fund."
                    
                 **Assumes that shareholder redeemed on the first day of the
                 second year and the contingent deferred sales charge was not
                 applicable for any of the periods shown. If the shareholder
                 had redeemed on the last day of the first year, the expenses
                 in the first year would have been $26.

                                      NUVEEN MUNICIPAL BOND FUND PROSPECTUS     
HOW TO DETERMINE IF THE FUND IS RIGHT FOR YOU
                                                                  
                                                               JULY 1, 1996     
                 There are many reasons why you might invest in the Fund.
                 These can include:
                 . lowering the tax burden on your investment income
                 . earning regular monthly dividends
                 . seeking to preserve your investment capital
                 . systematically setting money aside for retirement, college
                   funding or estate planning purposes
 
                 While there can be no assurance that the Fund will enable you
                 to achieve your individual investment goals, it has been
                 designed for investors who have these kinds of investment
                 goals in mind.
 
                 In addition, the Fund incorporates the following features and
                 benefits. You should carefully review the more detailed de-
                 scription of these features and benefits elsewhere in the
                 Prospectus to make sure they serve your individual investment
                 goals.
 
                 MONTHLY, TAX-FREE INCOME
                 The Fund provides monthly dividends exempt from regular
                 federal income tax.
 
                 DIVERSIFIED, INVESTMENT GRADE QUALITY PORTFOLIO
                 The Fund purchases investment grade quality Municipal
                 Obligations issued within the 50 states and certain U.S.
                 possessions or territories. The Fund is diversified and
                 maintains diversity within its portfolio by selecting
                 Municipal Obligations of different issuers. The Fund further
                 enhances its portfolio mix by purchasing Municipal
                 Obligations of different types and purposes and from
                 different geographic regions across the country.
 
                 EXPERIENCED MANAGEMENT
                    
                 The Fund is managed by Nuveen Advisory Corp. ("Nuveen
                 Advisory"), a wholly-owned subsidiary of John Nuveen & Co.
                 Incorporated ("Nuveen"). Founded in 1898, Nuveen is the
                 oldest and largest investment banking firm in the country
                 devoted exclusively to tax-exempt securities. Nuveen Advisory
                 currently manages 74 different tax-free portfolios
                 representing approximately $30 billion in assets.     
 
                 VALUE INVESTING
                 As a guiding policy, Nuveen Advisory's portfolio managers
                 seek investment grade quality, undervalued or underrated
                 Municipal Obligations which offer the best values among
                 Municipal Obligations of similar credit quality. By selecting
                 these Municipal Obligations, Nuveen Advisory seeks to
                 position the Fund better to achieve its investment objective
                 of as high a level of current interest income exempt from
 
                                         5
<PAGE>
 
                regular federal income tax as is consistent, in the view of
                the Fund's management, with preservation of capital,
                regardless of which direction the market may move.
                   
                NUVEEN RESEARCH     
                   
                Nuveen Advisory's portfolio managers call upon the resources
                of Nuveen's Research Department, the largest in the investment
                banking industry devoted exclusively to tax-exempt securities.
                Nuveen research analysts reviewed in 1995 more than $100
                billion of tax-exempt securities sold in new issue and
                secondary markets.     
                   
                LOW MINIMUMS     
                You can start earning tax-free income with a low initial
                investment of $1,000 in a particular class. See "How to Buy
                Fund Shares."
                   
                FLEXIBILITY IN PURCHASING FUND SHARES     
                          
                Each Fund has adopted a Flexible Pricing Program which is
                designed to permit you and your financial adviser to choose
                the method of purchasing shares that you believe is most
                beneficial given the amount of your investment and any current
                holdings of Fund shares, the length of time you expect to hold
                your investment, and other relevant circumstances. The Program
                features three alternative ways to purchase Fund shares
                (Classes A, C and R), each with a different combination of
                sales charges, ongoing fees, eligibility requirements, and
                other features. Please refer to "Flexible Pricing Program,"
                "How to Buy Fund Shares" and "How to Redeem Fund Shares" for a
                discussion of the Program's features and additional
                information about these three classes of shares.     
                          
                AUTOMATIC DEPOSIT PLANS     
                The Fund offers a number of investment options, including
                automatic deposit, direct deposit and payroll deduction, to
                help you add to your account on a regular basis.
                   
                AUTOMATIC REINVESTMENT     
                   
                All monthly dividends or capital gains paid with respect to
                each class of shares will be reinvested automatically into
                additional shares of the same class without a sales charge,
                unless you elect to receive them in cash. Separately,
                distributions from any Nuveen unit trust ("Nuveen UIT") may be
                used to buy Class A Shares and, under certain circumstances,
                Class R Shares, in either case without a sales charge at net
                asset value.     
                   
                EXCHANGE PRIVILEGE     
                   
                Shares of a class may be quickly and easily exchanged by
                telephone, without a sales charge for shares of the same or
                equivalent class of another Nuveen Mutual Fund or

                 for shares of certain Nuveen money market funds. Class R
                 Shares of the Fund may be exchanged for Class A Shares of the
                 Fund at any time, provided that the current net asset value
                 of those Class R Shares is at least $1,000 or you already own
                 Class A Shares.
                    
                 LIQUIDITY     
                           
                 You may redeem all or a portion of your Fund shares on any
                 business day at net asset value for the class of shares you
                 are redeeming. Class C Shares, as well as Class A purchases
                 of $1 million or more at net asset value, may be subject to a
                 contingent deferred sales charge ("CDSC") of 1% upon
                 redemption. Remember that share prices will fluctuate with
                 market conditions and upon redemption may be worth more or
                 less than their original cost. See "How to Redeem Fund
                 Shares."     
                    
                 AUTOMATIC WITHDRAWAL     
                 If you own shares totalling $10,000 or more, you can arrange
                 to have $50 or more sent to you from your account either
                 monthly or quarterly.
                    
                 TELEPHONE REDEMPTIONS     
                 You may establish free telephone redemption privileges for
                 your account.
                    
                 NO REDEMPTION FEES     
                 There are no fees imposed by the Fund for selling shares when
                 redeeming all or part of your holdings. However, your
                 financial adviser may charge you for serving as agent in the
                 redemption of shares.
                    
                 RISKS AND SPECIAL CONSIDERATIONS     
                    
                 You should consider certain other factors about the Fund
                 before investing. As with other bond mutual funds or any
                 long-term fixed-income investment, the value of the Fund's
                 portfolio will tend to vary inversely with changes in
                 prevailing interest rates. Accordingly, the Fund should be
                 considered a long-term investment, designed to provide the
                 best results when held for a multi-year period. The Fund may
                 not be suitable if you have a short-term investment horizon.
                 The Fund also has the ability to engage in certain investment
                 practices, including the purchase of Municipal Obligations
                 that pay interest subject to the federal alternative minimum
                 tax, the purchase or sale of securities on a when-issued or
                 delayed delivery basis and the purchase or sale of municipal
                 lease and installment purchase obligations. The Fund to date
                 has not invested in Municipal Obligations that pay interest
                 subject to the federal alternative minimum tax and has no
                 present intention of doing so. As described elsewhere in this
                 Prospectus, the Fund may engage in the investment practices
                 listed above only under strict limits.

                 will be achieved. This investment objective is a fundamental
                 policy of the Fund and may not be changed without the
                 approval of the holders of a majority of the shares of the
                 Fund. Other investment restrictions that may be changed only
                 with shareholder approval are contained in the Statement of
                 Additional Information.     
                    
                 HOW THE FUND PURSUES ITS OBJECTIVE 
The Fund seeks       
Municipal        Nuveen Advisory believes that in any market environment there
Obligations      are quality Municipal Obligations whose current price, yield,
considered to    credit quality and future prospects make them seem
be undervalued   underpriced or exceptionally attractive when compared with
                 other Municipal Obligations in the market. In selecting
                 investments for the Fund, Nuveen Advisory will attempt to
                 identify and purchase those undervalued or underrated
                 Municipal Obligations of investment grade quality that offer
                 the best values among Municipal Obligations of similar credit
                 quality. By selecting these Municipal Obligations, the Fund
                 will seek to provide attractive current tax-free income and
                 to protect the Fund's net asset value in both rising and
                 declining markets. In this way, regardless of the direction
                 the market may move, value investing, if successful, will
                 better position the Fund to achieve its investment objective
                 of as high a level of current interest income exempt from
                 regular federal income tax as is consistent, in the view of
                 the Fund's management, with preservation of capital. Any net
                 capital appreciation realized by the Fund will generally
                 result in the distribution of taxable capital gains to Fund
                 shareholders. See "Distributions and Taxes."     
       
                 Successful value investing depends on identifying and

help identify    the municipal market provides these opportunities, in part
values           because of the relatively large number of issuers of tax-
                 exempt securities and the relatively small number of full-
                 time, professional municipal market analysts. For example,
                 there are currently about 7,500 common stocks that are
                 followed by about 23,000 analysts. By contrast, there are
                 about 60,000 entities that issue tax-exempt securities and
                 less than 1,000 professional municipal market analysts.
 
                 Nuveen and Nuveen Advisory believe that together they employ
                 the largest number of research analysts in the investment
                 banking industry devoted exclusively to the

                 review and surveillance of tax-exempt securities. Their team
                 of more than 40 individuals has over 350 years of combined
                 municipal market experience. Nuveen and Nuveen Advisory have
                 access to information on approximately 60,000 municipal
                 issuers, and review annually more than $100 billion of tax-
                 exempt securities sold in new issue and secondary markets.

                 . temporary investments within the limitations and for the
                   purposes described below.
 
                 Municipal Obligations rated Baa are considered by Moody's to
                 be medium grade obligations which lack outstanding investment
                 characteristics and in fact have speculative characteristics
                 as well, while Municipal Obligations rated BBB are regarded
                 by S&P as having an adequate capacity to pay principal and
                 interest. Although the Fund to date has not done so and has
                 no present intention of doing so, the Fund may invest up to
                 20% of its net assets in Municipal Obligations that pay
                 interest subject to the federal alternative minimum tax ("AMT
                 Bonds"). The Fund intends to emphasize investments in
                 Municipal Obligations with long-term maturities in order to
                 maintain an average portfolio maturity of 20-30 years, but
                 the average maturity may be shortened from time to time
                 depending on market conditions in order to help limit the
                 Fund's exposure to market risk. As a result, the Fund's
                 portfolio at any given time may include both long-term and
                 intermediate-term Municipal Obligations.
 
                 Under ordinary circumstances, the Fund will invest
                 substantially all (at least 80%) of its net assets in
                 Municipal Obligations, and not more than 20% of its net
                 assets in "temporary investments," described below, provided
                 that temporary investments subject to regular federal income
                 tax and AMT Bonds may not comprise more than 20% of the
                 Fund's net assets. For defensive purposes, however, in order

                 circumstances affecting the municipal market, the Fund may
                 invest without limit in temporary investments. The Fund will
                 not be in a position to achieve its investment objective of
                 tax-exempt income to the extent it invests in taxable
                 temporary investments.
 
                 The foregoing investment policies are fundamental policies of

                 holders of a majority of the shares of the Fund.
                    
                 DESCRIPTION OF THE FUND'S INVESTMENTS     
   
Municipal Obligations
are issued by
states, cities
and local
authorities to
support a
variety of
public
activities
                    
                 Municipal Obligations, as the term is used in this
                 Prospectus, are federally tax-exempt debt obligations issued
                 by states, cities and local authorities and by certain U.S.
                 possessions or territories to obtain funds for various public
                 purposes, such as the construction of public facilities, the
                 payment of general operating expenses and the refunding of
                 outstanding debts. They may also be issued to obtain funding
                 for various private activities, including loans to finance
                 the construction of housing, educational and medical
                 facilities or privately owned industrial development and
                 pollution control projects.     
 
                 The two principal classifications of Municipal Obligations
                 are general obligation and revenue bonds. GENERAL OBLIGATION
                 bonds are secured by the issuer's pledge of its full faith,
                 credit and taxing power for the payment of principal and
                 interest. REVENUE bonds are payable only from the revenues
                 derived from a particular facility or class of facilities or,
                 in some cases, from the proceeds of a special excise or other
                 specific revenue source. Industrial development and pollution
                 control bonds are in most cases revenue bonds and do not
                 generally constitute the pledge of the credit or taxing power
                 of the issuer of these bonds.
 
                 Municipal Obligations may also include participations in
                 lease obligations or installment purchase contract
                 obligations (collectively, "lease obligations") of municipal
                 authorities or entities. Certain "non-appropriation" lease
                 obligations may present special risks because the
                 municipality's obligation to make future lease or installment
                 payments depends on money being appropriated each year for
                 this purpose. The Fund will seek to minimize these risks by
                 not investing more than 10% of its assets in non-
                 appropriation lease obligations, and by only investing in
                 those non-appropriation lease obligations that meet certain
                 criteria of the Fund. See the Statement of Additional
                 Information for further information about lease obligations.

                 The yields on Municipal Obligations depend on a variety of
                 factors, including the condition of financial markets in
                 general and the municipal market in particular, as well as
                 the size of a particular offering, the maturity of the
                 obligation and the rating of the issue. Certain Municipal
                 Obligations may pay variable or floating rates of interest
                 based upon certain market rates or indexes such as a bank
                 prime rate or a tax-exempt money market index. The ratings of
                 Moody's and S&P represent their opinions as to the quality of
                 the Municipal Obligations that they undertake to rate. It
                 should be emphasized, however, that ratings are general and
                 are not absolute standards of quality. Consequently,
                 Municipal Obligations with the same maturity, coupon and
                 rating may have different yields, while those having the same
                 maturity and coupon with different ratings may have the same
                 yield. The market value of Municipal Obligations will vary
                 with changes in prevailing interest rate levels and as a
                 result of changing evaluations of the ability of their
                 issuers to meet interest and principal payments. Similarly,
                 the market value and net asset value of shares of the Fund
                 will change in response to interest rate changes; they will
                 tend to decrease when interest rates rise and increase when
                 interest rates fall.

                 taxable securities. The Fund will invest only in those
                 taxable temporary investments that are either U.S. Government
                 securities or are rated within the highest grade by Moody's
                 or S&P, and mature within one year from the date of purchase
                 or carry a variable or floating rate of interest. See the
                 Statement of Additional Information for further information
                 about the temporary investments in which the Fund may invest.

                                      NUVEEN MUNICIPAL BOND FUND PROSPECTUS     
                                                                  
                                                               JULY 1, 1996     
           
When-issued or   The Fund may purchase and sell Municipal Obligations on a
delayed          when-issued or delayed delivery basis, which calls for the
delivery         Fund to make payment or take delivery at a future date,
transactions     normally 15-45 days after the trade date. 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. A Fund commonly engages 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. See the Statement of Additional Information for
                 further information about when-issued and delayed delivery
                 transactions.     
 
                 The Fund has adopted certain fundamental policies intended to

investment       with these policies, the Fund may not:

                   holdings would exceed 10% of the total assets of the Fund.
 
                 In applying these policies, the "issuer" of a security is
                 deemed to be the entity whose assets and revenues are
                 committed to the payment of principal and interest on that
                 security, provided that the guarantee of an instrument will
                 generally be considered a separate security.
                    
                 Except as specifically noted above or in the Statement of
                 Additional Information, the Fund's investment policies are
                 not fundamental and may be changed without shareholder
                 approval. For a more complete description of investment
                 restrictions that may be changed without a shareholder vote,

FLEXIBLE PRICING PROGRAM     
               
The Fund         The Fund has adopted a Flexible Pricing Program that offers
offers various   you three alternative ways to purchase Fund shares (Classes
methods of       A, C and R), each with a different combination of sales
purchasing       charges, ongoing fees, eligibility requirements, and other
shares which     features. The Program is designed to permit you and your

needs and        circumstances. A summary of the three alternatives is set
preferences      forth below:

                 purchases of $50,000 or more. The up-front sales charge may
                 be reduced or waived for certain purchases.     
                    
                 (2) Certain Class A purchases at net asset value of $1
                 million or more may be subject to a 1% CDSC if redeemed
                 within 18 months of purchase.     
                    
                 (3) The CDSC is applicable to Class C Shares redeemed within
                 12 months of purchase. Class C Shares convert to Class A
                 Shares after six years, which reduces the ongoing expenses
                 borne by an investor.     
                    
                 For more information regarding features of each class, see
                 "How to Buy Fund Shares," "How to Redeem Fund Shares" and
                 "Distribution and Service Plan" below.     
             
Which option     When you purchase Class A Shares, you will normally pay an
is right for     up-front sales charge. As a result, you will have less money
you?             invested initially and you will own fewer Class A Shares than
                 you would in the absence of an up-front sales charge.
                 Alternatively, when you purchase Class C Shares, you will not
                 pay an up-front sales charge and all of your monies will be
                 fully invested at the time of purchase. However, Class C
                 Shares are subject to an annual distribution fee which
                 constitutes an asset-based sales charge whose purpose is the
                 same as an up-front sales charge. Class C Shares
                 automatically convert to Class A Shares six years after
                 purchase, which reduces the annual expenses you would bear.
                 This automatic conversion is designed to ensure that holders
                 of Class C Shares would pay over the six-year period a
                 distribution fee that is approximately the economic
                 equivalent of the one-time, up-front sales charge paid by
                 holders of Class A Shares on purchases of up to $50,000.
                 Class C Shares are subject to a CDSC of 1% if redeemed within
                 12 months of purchase. Class A Shares and Class C Shares are
                 subject to annual service fees which are identical in amount
                 and are used to compensate Authorized Dealers for providing
                 you with ongoing account services. You may qualify for a
                 reduced sales charge or a sales charge waiver

                 on a purchase of Class A Shares, as described below under
                 "How the Sales Charge on Class A Shares May Be Reduced or
                 Waived." Class R Shares are available for purchase at a price
                 equal to their net asset value, but only under certain
                 circumstances or for certain categories of investors, as
                 described below under "How to Buy Fund Shares--Class R
                 Shares."     
                    
                 In deciding whether to purchase Class A Shares, Class C
                 Shares or Class R Shares, you should consider all relevant
                 factors, including the dollar amount of your purchase, the
                 length of time you expect to hold the shares and whether a
                 CDSC would apply, the amount of any applicable up-front sales
                 charge, the amount of any applicable distribution or service
                 fee that may be incurred while you own the shares, whether or
                 not you will be reinvesting income or capital gain
                 distributions in additional shares, whether or not you meet
                 applicable eligibility requirements or qualify for a sales
                 charge waiver or reduction, and the relative level of
                 services that your financial adviser may provide to different
                 classes. Authorized Dealers and other persons distributing
                 the Fund's shares may receive different compensation for
                 selling different classes of shares.     
     
Differences      Each class of shares represents an interest in the same
between the      portfolio of investments. Each class of shares is identical
classes of       in all respects except that each class has its own sales
shares           charge structure, each class bears its own class expenses,
                 including service and distribution fees, and each class has
                 exclusive voting rights with respect to any distribution or
                 service plan applicable to its shares. In addition, the Class
                 C Shares are subject to a conversion feature and a CDSC of 1%
                 if redeemed within 12 months of purchase, as described below.
                 As a result of the differences in the expenses borne by each
                 class of shares, and differences in the purchase and
                 redemption activity for each class, net income per share,
                 dividends per share and net asset value per share will vary
                 among the Fund's classes of shares.     
 
Dealer              
Incentives       Upon notice to all Authorized Dealers, Nuveen may reallow to
                 Authorized Dealers electing to participate up to the full
                 applicable Class A Share up-front sales charge during periods
                 and for transactions specified in the notice. The
                 reallowances made during these periods may be based upon
                 attainment of minimum sales levels. Further, 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 the Funds or other Nuveen Mutual Funds and
                 Nuveen UITs during specified time periods. The staff of the
                 Securities and Exchange Commission takes the position that
                 dealers who receive 90% or more of the applicable sales
                 charge may be deemed underwriters under the Securities Act of
                 1933, as amended.

                 Nuveen may also from time to time provide additional
                 promotional support to certain Authorized Dealers who sell or
                 are expected to sell certain minimum amounts of Nuveen Mutual
                 Funds and Nuveen UITs during specified time periods. Such
                 promotional support may include providing sales literature to
                 and holding informational or educational programs for the
                 benefit of such Authorized Dealers' representatives, seminars
                 for the public, and advertising and sales campaigns.
                 Specifically, Nuveen offers a program of advertising support
                 to Authorized Dealers under which Nuveen will pay or
                 reimburse the Authorized Dealer for up to one-half of

                 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 UIT,
                 or otherwise.
 
                 By establishing a Letter of Intent, you agree that your first
                 purchase of Class A Shares 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 SSI
                 whenever you make a purchase of Fund shares that you wish to
                 be covered under the Letter of Intent option.

                 CLASS C SHARES 
Class C Shares   
may be           You may purchase Class C Shares at a public offering price
purchased at     equal to the applicable net asset value per share without any
their net        up-front sales charge. Class C Shares are subject to an
asset value,     annual distribution fee to reimburse Nuveen for costs
and are          incurred in connection with the sale of Class C Shares. Class
subject to an    C Shares are also subject to an annual service fee to
annual           compensate Authorized Dealers for providing you with ongoing
distribution     financial advice and other services. See "Distribution and
fee              Service Plan."     
                    
                 An investor purchasing Class C Shares agrees to pay a CDSC of
                 1% if Class C Shares are redeemed within 12 months of
                 purchase. See "How to Redeem Fund Shares." The Class C Shares
                 of the Fund will effectively retain the CDSC; the Fund will
                 pay the amount of the CDSC to Nuveen, but will be reimbursed
                 by Nuveen in an equal amount by a reduction in the
                 distribution fees payable to Nuveen.     
                    
                 Class C Shares will automatically convert to Class A Shares
                 six years after purchase. All such conversions will be done
                 at net asset value without the imposition of any sales
                 charge, fee, or other charge, so that the value of each
                 shareholder's account immediately before conversion will be
                 the same as the value of the account immediately after
                 conversion. Class C Shares acquired through reinvestment of
                 distributions will convert into Class A Shares based on the
                 date of the initial purchase to which such shares relate. For
                 this purpose, Class C Shares acquired through reinvestment of
                 distributions will be attributed to particular purchases of
                 Class C Shares in accordance with such procedures as the
                 Board of Trustees may determine from time to time. The
                 automatic conversion of Class C Shares to Class A Shares six
                 years after purchase was designed to ensure that holders of
                 Class C Shares would pay over the six-year period a
                 distribution fee that is approximately the economic
                 equivalent of the one-time, up-front sales charge paid by
                 holders of Class A Shares on purchases of up to $50,000.
                 Class C Shares that are converted to Class A Shares will no
                 longer be subject to an annual distribution fee, but they
                 will remain subject to an annual service fee that is
                 identical in amount for both Class C Shares and Class A
                 Shares. Since net asset value per share of the Class C Shares
                 and the Class A Shares may differ at the time of conversion,
                 a shareholder may receive more or fewer Class A Shares than
                 the number of Class C Shares converted. Any conversion of
                 Class C Shares into Class A Shares will be subject to the
                 continuing availability of an opinion of counsel or a private
                 letter ruling from the Internal Revenue Service to the effect
                 that the conversion of shares would not constitute a taxable
                 event under federal income tax law. Conversion of Class C
                 Shares into Class A Shares might be suspended if such an
                 opinion or ruling were no longer available.

                 CLASS R SHARES     
Class R Shares  
are offered at   If you owned Fund shares as of June 13, 1995, those shares
their net        have been designated as Class R Shares. Purchases of
asset value      additional Class R Shares, which will not be subject to any
                 sales charge or any distribution or service fee, will be
                 limited to the following circumstances. You may purchase
                 Class R Shares with monies representing distributions from
                 Nuveen-sponsored UITs if, prior to June 13, 1995, you had
                 purchased such UITs and elected to reinvest distributions
                 from such UITs in shares of the Fund. You may also purchase
                 Class R Shares with monies representing dividends and capital
                 gain distributions on Class R Shares of the Fund. You may
                 purchase Class R Shares if you are making a purchase of $1
                 million or more of Fund shares in a single transaction.
                 Finally, you may purchase Class R Shares if you are within
                 the following specified categories of investors who are also
                 eligible to purchase Class A Shares at net asset value
                 without an up-front sales charge: officers, trustees and
                 retired directors and trustees of the Fund or its
                 predecessor; 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; bank or broker-affiliated
                 trust departments; investors who purchase through broker-
                 dealer sponsored mutual fund purchase programs offered on a
                 periodic fee, asset-based fee or no transaction fee basis;
                 and clients of investment advisers, financial planners or
                 other financial intermediaries that charge periodic or asset-
                 based fees for their services.     
                    
                 If you are eligible to purchase either Class R Shares or
                 Class A Shares without a sales charge at net asset value you
                 should be aware of the differences between these two classes
                 of shares. Class A Shares are subject to an annual service
                 fee to compensate Authorized Dealers for providing you with
                 ongoing account services. Class R Shares are not subject to a
                 service fee and consequently holders of Class R Shares may
                 not receive the same types or levels of services from
                 Authorized Dealers. In choosing between Class A Shares and
                 Class R Shares, you should weigh the benefits of the services
                 to be provided by Authorized Dealers against the annual
                 service fee imposed upon the Class A Shares.

                 must also furnish the information necessary to establish your
                 Fund account by completing and enclosing with your payment
                 the attached Application Form. After your initial investment,
                 you may make subsequent purchases at any time by forwarding

                 must be in U.S. dollars and should be sent directly to SSI at
                 its address listed on the back cover of this Prospectus. A

                 order of the Fund generally will not be acceptable. You may
                 also wire Federal Funds directly to SSI, but you may be
                 charged a fee for this. For instructions on how to make Fund
                 purchases by wire transfer, call Nuveen toll-free at
                 800.621.7227, between the hours of 8:30 a.m. and 8:00 p.m.

                 MINIMUM INVESTMENT REQUIREMENTS     
                 Generally, your first purchase of any class of the Fund's
                 shares must be for $1,000 or more. Additional purchases may
                 be in amounts of $100 or more. These minimums may be changed
                 at any time by the Fund. There are exceptions to these
                 minimums for shareholders who qualify under one or more of
                 the Fund's automatic deposit, group purchase or reinvestment
                 programs.
                    
                 PURCHASE PRICE     
                    
                 The price at which the purchase of Fund shares is effected is
                 based on the next calculation of the Fund's net asset value
                 after the order is placed. The Fund's net asset value per
                 share is determined as of 4:00 p.m. Eastern Time on each day
                 the New York Stock Exchange is open for business. See "Net
                 Asset Value," below for a description of how net asset value
                 is calculated.     
                    
                 SYSTEMATIC INVESTMENT PROGRAMS     
                    
                 The Fund offers you several opportunities to capture the
                 benefits of "dollar cost averaging" through systematic
                 investment programs. In a regularly followed dollar cost
                 averaging program, you would purchase more shares when Fund
                 share prices are lower and fewer shares when Fund share
                 prices are higher, so that the average price paid for Fund
                 shares is less than the average price of the Fund shares over
                 the same time 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. The chart below shows the cumulative effect that
                 compound interest can have on a systematic investment
                 program.

                 In the above example, it is assumed that $100 is added to an
                 investment account every month for 20 years. From the same
                 $1,000 beginning, the chart shows the amount that would be in
                 the account after 20 years, assuming no interest and interest

                 differences between the Fund and the hypothetical investment
                 program shown. This example assumes no gain or loss in the
                 net asset value of the

                 investment over the entire 20-year period, whereas the net
                 asset value of the Fund will rise and fall due to market
                 conditions or other factors, which could have a significant
                 impact on the total value of your investment. Similarly, this
                 example shows four steady interest rates over the entire 20-
                 year period, whereas the dividend rate of the Fund can be
                 expected to fluctuate over time. The Fund may provide
                 additional information to investors and advisers illustrating
                 the benefits of systematic investment programs and dollar

                 regular investments in an amount of $25 or more each month by
                 authorizing SSI to draw preauthorized checks on your bank
                 account. There is no obligation to continue payments and you
                 may terminate your participation at any time at your
                 discretion. No charge in addition to the applicable sales
                 charge is made in connection with this Plan, and there is no
                 cost to the Fund. To obtain an application form for the

Payroll Direct   Once you have established a Fund account, you may, with your
Deposit Plan     employer's consent, make regular investments in Fund shares
                 of $25 or more per pay period by authorizing your employer to
                 deduct this amount automatically from your paycheck. There is
                 no obligation to continue payments and you may terminate your
                 participation at any time at your discretion. No charge in
                 addition to the applicable sales charge is made for this
                 Plan, and there is no cost to the Fund. To obtain an

                 the same or equivalent class of another Nuveen Mutual Fund
                 with reciprocal exchange privileges, at net asset value

                 for the same class of shares of the Fund at net asset value
                 without a sales charge. Exchanges of shares from any Nuveen

                 class of the Fund may be exchanged for shares of any Nuveen
                 money market fund.     
                    
                 No CDSC will be charged on the exchange of Class C Shares of
                 any Fund for Class C Shares of any other Nuveen Mutual Fund
                 or shares of any Nuveen money market fund. The 12 month
                 holding period for purposes of the CDSC applicable to Class C
                 Shares will continue to run during any period in which Class
                 C Shares of the Fund, Class C Shares of any other Nuveen
                 Mutual Fund or shares of a Nuveen money market fund are held.
                        
                 The shares to be purchased must be offered in your state of
                 residence and you must have held the shares you are
                 exchanging for at least 15 days. The total value of exchanged
                 shares must at least equal the minimum investment requirement
                 of the Nuveen Mutual Fund being purchased. For federal income
                 tax purposes, any exchange constitutes a sale and purchase of
                 shares and may result in capital gain or loss. Before making
                 any exchange, you should obtain the Prospectus for the Nuveen
                 Mutual Fund you are purchasing and read it carefully. If the
                 registration of the account for the Fund you are purchasing
                 is not exactly the same as that of the fund account from
                 which the exchange is made, written instructions from all
                 holders of the account from which the exchange is being made
                 must be received, with signatures guaranteed by a member of
                 an approved Medallion Guarantee Program or in such other
                 manner as may be acceptable to the Fund. You may also
                 exchange shares by telephone if you authorize telephone
                 exchanges by checking the applicable box on the enclosed
                 Application Form or by calling Nuveen toll-free
                 at800.621.7227 to obtain an authorization form. The exchange
                 privilege may be modified or discontinued by the Fund at any
                 time upon prior written notice to shareholders of the Fund.
                        
                 In addition, you may exchange Class R Shares of the 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
                 $1,000 or you already own Class A Shares of the Fund.     
                    
                 The exchange privilege is not intended to permit the Fund to
                 be used as a vehicle for short-term trading. Excessive
                 exchange activity may interfere with portfolio management,
                 raise expenses, and otherwise have an adverse effect on all
                 shareholders. In order to limit excessive exchange activity
                 and in other circumstances where Fund

                 management believes doing so would be in the best interest of
                 the Fund, the Fund reserves the right to revise or terminate
                 the exchange privilege, or limit the amount or number of
                 exchanges or reject any exchange. Shareholders would be
                 notified of any such action to the extent required by law.
                                      
    
   
Reinstatement    If you have redeemed Class A Shares of the Fund or Class A
Privilege        Shares of any other Nuveen Mutual Fund that were subject to a
                 sales charge or a CDSC, you have up to one year to reinvest
                 all or part of the full amount of the redemption in the same
                 class of shares of the Fund at net asset value. This
                 reinvestment privilege can be exercised only once for any
                 redemption, and reinvestment will be made at the net asset
                 value of the appropriate class of Fund shares next calculated
                 after reinstatement. If you reinstate shares that were
                 subject to a CDSC, your holding period as of the redemption
                 date will also be reinstated. The tax consequences of any
                 capital gain realized on a redemption will not be affected by
                 reinstatement, but a capital loss may be disallowed in whole
                 or in part depending on the timing and amount of the
                 reinvestment. [/R]

                 ADDITIONAL INFORMATION
                    
                 If you choose to invest in the Fund, an account will be
                 opened and maintained for you by SSI, the Fund's shareholder
                 services agent. Share certificates will be issued to you only
                 upon written request to SSI, and no certificates will be
                 issued for fractional shares. The Fund reserves the right to
                 reject any purchase order and to waive or increase minimum
                 investment requirements. A change in registration or transfer
                 of shares held in the name of your financial adviser's firm
                 can only be made by an order in good form from the financial
                 adviser acting on your behalf.     
 
                 Authorized Dealers are encouraged to open single master
                 accounts. However, some Authorized Dealers may wish to use
                 SSI's sub-accounting system to minimize their internal
                 recordkeeping requirements. An Authorized Dealer or other
                 investor requesting shareholder servicing or accounting other
                 than the master account or sub-accounting service offered by
                 SSI will be required to enter into a separate agreement with
                 another agent for these services for a fee that will depend
                 upon the level of services to be provided.
                    
                 Subject to the rules and regulations of the Securities and
                 Exchange Commission, the Fund reserves the right to suspend
                 the continuous offering of its shares at any time, but no
                 suspension shall affect your right of redemption as described
                 below.

DISTRIBUTION AND SERVICE PLAN     
                 The Fund has adopted a plan (the "Plan") pursuant to Rule
                 12b-1 under the Investment Company Act of 1940, which
                 provides that Class C Shares will be subject to an annual
                 distribution fee, and that both Class A 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 C Shares under the
                 Plan will be payable to reimburse Nuveen for services and
                 expenses incurred in connection with the distribution of
                 Class C Shares. The distribution fee primarily reimburses
                 Nuveen for providing compensation to Authorized Dealers,
                 including Nuveen, either at the time of sale or on an ongoing
                 basis. The other expenses for which Nuveen may be reimbursed
                 include, 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 C Shares, certain
                 other expenses associated with the distribution of Class C
                 Shares, and any other distribution-related expenses that may
                 be authorized from time to time by the Board of Trustees.
                        
                 The service fee applicable to Class A Shares and Class C
                 Shares under the Plan will be payable to Nuveen, to be used
                 to compensate Authorized Dealers, including Nuveen, 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.     
 
                 The Fund may spend up to .25 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. The Fund may spend up to
                 .75 of 1% per year of the average daily net assets of Class C
                 Shares less the amount of any CDSC received by Nuveen as to
                 which no reinstatement privilege has been exercised, as a
                 distribution fee and up to .25 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.

HOW TO REDEEM FUND SHARES             NUVEEN MUNICIPAL BOND FUND PROSPECTUS     
                                                                  
                                                               JULY 1, 1996     
                    
                 You may require the Fund at any time to redeem for cash your
                 shares of the Fund. All shares will be redeemed at the net
                 asset value next computed after instructions and required
                 documents and certificates, if any, are received in proper
                 form as described below. However, with respect to certain
                 Class A and Class C shares, as further described below, any
                 applicable contingent deferred sales charge will be deducted
                 from the proceeds of the redemption. There is no charge for
                 redemption of Class R Shares.     
                
Contingent       Class A Shares are normally redeemed at net asset value,
Deferred Sales   without any CDSC. However, in the case of Class A Shares
Charge           purchased at net asset value 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. See "How to Buy Fund
                 Shares--Class A Shares." Class C Shares are normally 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. See "How to Buy Fund
                 Shares--Class C Shares." The CDSC will be based on 1% of the
                 lower of (i) the net asset value of shares at the time of
                 purchase or (ii) the net asset value of shares at the time of
                 redemption.     
                    
                 In determining whether a CDSC is payable, a Fund will first
                 redeem shares not subject to any charge, and then in the
                 reverse order in which the shares were purchased, except if
                 another order of redemption would result in a lower charge or
                 you specify 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
                 money market fund. Your 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
                 you pay on Class A Shares. The CDSC may be waived under
                 certain special circumstances, as described in the Statement
                 of Additional Information.     
                    
                 THE FUND OFFERS A VARIETY OF REDEMPTION OPTIONS 
By Written      
Request          You may redeem shares by sending a written request for

                    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 75% 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.
 
                    For the services and facilities furnished by Nuveen Advi-
                    sory, the Fund has agreed to pay an annual management fee

                    All fees and expenses are accrued daily and deducted be-
                    fore payment of dividends to investors. In addition to the
                    management fee of Nuveen Advisory, the Fund pays all its
                    other costs and expenses of its operations. Nuveen Advi-
                    sory has agreed to waive all or a portion of its manage-
                    ment fee or reimburse certain expenses of the Fund in or-
                    der to prevent total operating expenses (excluding any
                    distribution or service fees) in any fiscal year from ex-

                    February 28, 1995, the management fee amounted to .45 of
                    1% of the average daily net assets, and the Fund's total
                    operating expenses amounted to .59 of 1% of the average
                    net assets.
 
                    Portfolio Management. Overall portfolio management strat-
                    egy and the day-to-day management of the Fund is the re-
                    sponsibility of Thomas C. Spalding, Jr., a Vice President
                    of Nuveen Advisory and of the Fund. Mr. Spalding has
                    served as the portfolio manager of the Fund since August,
                    1978. Mr. Spalding has been employed by Nuveen since 1976
                    and by Nuveen Advisory since 1978 and has responsibility
                    with respect to the portfolio management of all Nuveen
                    open-end and exchange-traded funds managed by Nuveen Advi-
                    sory. See the Statement of Additional Information for fur-
                    ther information about Mr. Spalding.
 
                    Consistent with the Fund's investment objectives, the day-
                    to-day management of the Fund is characterized by an em-
                    phasis on value investing, a process that involves the
                    search for Municipal Obligations with favorable
                    characteristics that, in Nuveen Advisory's judgment, have
                    not yet been recognized in the marketplace. The process of
                    searching for such undervalued or underrated securities is
                    an ongoing one that draws upon the re sources of the
                    portfolio managers of the various Nuveen funds and senior
                    management of Nuveen Advisory. All portfolio management

                 WIRE. Proceeds of redemptions through Fund Direct will
                 normally be wired to     
                    
                 your Fund Direct bank account on the second or third day
                 after the redemption.     
                    
                 Before you may redeem shares by TEL-A-CHECK, TEL-A-WIRE or
                 Fund Direct, you must complete the appropriate authorization
                 section of the enclosed Application Form or the Fund Direct
                 Application Form and return it to Nuveen or SSI. If you did
                 not authorize one or more of these redemption methods when
                 you opened your account, you may obtain a redemption
                 authorization form by writing the Fund or by calling Nuveen
                 toll-free at 800.621.7227. Proceeds of share redemptions made
                 by TEL-A-WIRE will be transferred by Federal Reserve wire
                 only to the commercial bank account specified by the
                 shareholder on the Application Form. You must send a written
                 request to Nuveen or SSI in order to establish multiple
                 accounts, or to change the account or accounts designated to
                 receive redemption proceeds. These requests must be signed by
                 each account owner with signatures guaranteed by a member of
                 an approved Medallion Guarantee Program or in such other
                 manner as may be acceptable to the Fund. Further
                 documentation may be required from corporations, executors,
                 trustees or personal representatives.     
                           
                 For the convenience of shareholders, the Fund has authorized
                 Nuveen as its agent to accept orders from financial advisers
                 by wire or telephone for the redemption of Fund shares. The
                 redemption price is the net asset value next determined
                 following receipt of an order placed by the financial
                 adviser. The Fund makes payment for the redeemed shares to
                 the securities representatives who placed the order promptly
                 upon presentation of required documents with signatures
                 guaranteed as described above. Neither the Fund nor Nuveen
                 charge any redemption fees other than the CDSC as described
                 above. However, your financial adviser may charge you for
                 serving as agent in the redemption of shares.     
                    
                 The Fund reserves the right to refuse telephone redemptions
                 and, at its option, may limit the timing, amount or frequency
                 of these redemptions. Telephone redemption procedures may be
                 modified or terminated at any time, on 30 days' notice, by
                 the Fund. The Fund, SSI and Nuveen will not be liable for
                 following telephone instructions reasonably believed to be
                 genuine. The Fund employs procedures reasonably designed to
                 confirm that telephone instructions are genuine. These
                 procedures include recording all telephone instructions and
                 requiring up to three forms of identification prior to acting
                 upon a caller's instructions. If the Fund does not follow
                 reasonable procedures for protecting shareholders against
                 loss on telephone transactions, it may be liable for any
                 losses due to unauthorized or fraudulent telephone
                 instructions.

Automatic        If you own Fund shares currently worth at least $10,000, you
Withdrawal       may establish an Automatic Withdrawal Plan by completing an
Plan             application form for the Plan. You may obtain an application
                 form by checking the applicable box on the enclosed
                 Application Form or by calling Nuveen toll-free at
                 800.621.7227. [/R]
 
                 The Plan permits you to request periodic withdrawals on a
                 monthly, quarterly, semi-annual or annual basis in an amount
                 of $50 or more. Depending upon the size of the withdrawals
                 requested under the Plan and fluctuations in the net asset
                 value of Fund shares, these withdrawals may reduce or even
                 exhaust your account.
                    
                 The purchase of Class A Shares, other than through
                 reinvestment, while you are participating in the Automatic
                 Withdrawal Plan with respect to Class A Shares will usually
                 be disadvantageous because you will be paying a sales charge
                 on any Class A Shares you purchase at the same time you are
                 redeeming shares. Similarly, use of the Automatic Withdrawal
                 Plan for Class C Shares held for less than 12 months or
                 certain Class A Shares held for less than 18 months may be
                 disadvantageous because the newly-purchased shares may be
                 subject to the 1% CDSC.     
 
                 The Fund may suspend the right of redemption of Fund shares
General          or delay payment more than seven days (a) during any period
                 when the New York Stock Exchange is closed (other than
                 customary weekend and holiday closings), (b) when trading in
                 the markets the Fund normally utilizes is restricted, or an
                 emergency exists as determined by the Securities and Exchange
                 Commission so that trading of the Fund's investments or
                 determination of its net asset value is not reasonably
                 practicable, or (c) for any other periods that the Securities
                 and Exchange Commission by order may permit for protection of
                 Fund shareholders.
 
                 The Fund may, from time to time, establish a minimum total
                 investment for Fund shareholders, and the Fund reserves the
                 right to redeem your shares if your investment is less than
                 the minimum after giving you at least 30 days' notice. If any
                 minimum total investment is established, and if your account
                 is below the minimum, you will be allowed 30 days following
                 the notice in which to purchase sufficient shares to meet the
                 minimum. So long as the Fund continues to offer shares at net
                 asset value to holders of Nuveen UITs who are investing their
                 Nuveen UIT distributions, no minimum total investment will be
                 established for the Fund.

                 (the "Nuveen Exchange-Traded Funds"). Each of these invests
                 substantially all of its assets in investment grade quality,
                 tax-free municipal securities, and except for money-market
                 funds, adheres to the value investing strategy described

                 management fee of Nuveen Advisory, the Fund pays all its
                 other costs and expenses of its operations. Nuveen Advisory
                 has agreed to waive all or a portion of its management fee or
                 reimburse certain expenses of the Fund in order to prevent
                 total operating expenses (excluding any distribution or
                 service fees) in any fiscal year from exceeding .75 of 1% of
                 the average daily net asset value of any class of shares of
                 the Fund. For information regarding the management fees and
                 total operating expenses of each class of shares for the year

                 Spalding, Jr., a Vice President of Nuveen Advisory and of the
                 Fund. Mr. Spalding has served as the portfolio manager of the
                 Fund since August, 1978. Mr. Spalding has been employed by
                 Nuveen since 1976 and by Nuveen Advisory since 1978 and has
                 responsibility with respect to the portfolio management of
                 all Nuveen open-end and exchange-traded funds managed by
                 Nuveen Advisory. See the Statement of Additional Information

                 Consistent with the Fund's investment objectives, the day-to-
                 day management of the Fund is characterized by an emphasis on
                 value investing, a process that involves the search for
                 Municipal Obligations with favorable characteristics that, in
                 Nuveen Advisory's judgment, have not yet been recognized in
                 the marketplace. The process of searching for such
                 undervalued or underrated securities is an ongoing one that
                 draws upon the resources of the portfolio managers of the
                 various Nuveen funds and senior management of Nuveen
                 Advisory. All portfolio management decisions are subject to
                 weekly review by Nuveen Advisory's management and to
                 quarterly review by the Fund's Board of Trustees.

HOW THE FUND SHOWS PERFORMANCE           
                                      NUVEEN MUNICIPAL BOND FUND PROSPECTUS     
                                                                  
                                                               JULY 1, 1996     
                 The Fund from time to time may quote various performance
                 measures in order to illustrate the historical returns
                 available from an investment in the Fund. These performance
                 measures, which are determined for each class of shares of
                 the Fund, include:
 
                 YIELD is a standardized measure of the net investment income
Yield            earned over a specified 30-day period, expressed as a
Information      percentage of the offering price per share at the end of the
                 period. Yield is an annualized figure, which means that it is
                 assumed that the same level of net investment income is
                 generated over a one-year period.
                    
                 TAXABLE EQUIVALENT YIELD is the yield that a taxable
                 investment would need to generate in order to equal the yield
                 on an after-tax basis for an investor in a stated tax
                 bracket. Taxable equivalent yield will consequently be higher
                 than its yield. See the chart below and "Taxable Equivalent
                 Yield Tables" for examples of taxable equivalent yields and
                 how you can use them to compare other investments with
                 investments in the Fund.

                 As this chart shows, interest rates on various long- and
                 short-term investments will fluctuate over time, and not
                 always in the same direction or to the same degree. For
                 convenience, the taxable equivalent yield of the Bond Buyer
                 20 Index shown here was calculated using a 36% federal income
                 tax rate. Other federal income tax rates, both higher and
                 lower, were in existence for all or part of the period shown
                 in the chart. This chart is not intended to predict the
                 future direction of interest rates. See the discussion below
                 under the subcaption "General" for a description of the
                 indices and investments shown in the chart.
 
                 DISTRIBUTION RATE is determined based upon the latest
                 dividend, annualized, expressed as a percentage of the
                 offering price per share at the end of the measurement
                 period. Distribution rate may sometimes be different than
                 yield because it may not reflect amortization of bond
                 premiums to the extent such premiums arise after the bonds
                 were purchased.
 
                 AVERAGE ANNUAL TOTAL RETURN and CUMULATIVE TOTAL RETURN
Total return     figures for a specified period measure both the net
information      investment income generated by, and the effect of any
                 realized and unrealized appreciation or depreciation of, an
                 investment in the Fund, assuming the reinvestment of all
                 dividends and capital gain distributions. Average annual
                 total return figures generally are quoted for at least one-,
                 five- and ten-year (or life-of-fund, if shorter) periods and
                 represent the average annual percentage change over those
                 periods. Cumulative total return figures are not annualized
                 and represent the cumulative percentage or dollar value
                 change over the period specified.
 
                 TAXABLE EQUIVALENT TOTAL RETURN represents the total return
                 that would be generated by a taxable income fund that
                 produced the same amount of net asset value appreciation or
                 depreciation and after-tax income as the Fund in each year,
                 assuming a specified tax rate. The taxable equivalent total
                 return of the Fund will therefore be higher than its total
                 return over the same period.
 
                 From time to time, the Fund may compare its risk-adjusted
                 performance with other investments that may provide different
                 levels of risk and return. For example, the Fund may compare
                 its risk level, as measured by the variability of its
                 periodic returns, or its RISK-ADJUSTED TOTAL RETURN, with
                 those of other funds or groups of funds. Risk-adjusted total
                 return would be calculated by adjusting each investment's
                 total return to account for the risk level of the investment.

                 The Fund may also compare its TAX-ADJUSTED TOTAL RETURN with
                 that of other funds or groups of funds. This measure would
                 take into account the tax-exempt nature of exempt-interest
                 dividends and the payment of income taxes on the Fund's
                 distributions of net realized capital gains and ordinary
                 income.
   
General          Any given performance quotation or performance comparison for
                 the Fund is based on historical earnings and should not be
                 considered as representative of the performance of the Fund
                 for any future period. See the Statement of Additional
                 Information for further information concerning the Fund's
                 performance. For information as to current yield and other

                 A comparison of the current yield or historic performance of
                 the Fund to those of other investments is one element to
                 consider in making an informed investment decision. The 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 Fund.
                 Additionally, the Fund may compare its current yield or total
                 return history with a widely-followed, unmanaged municipal
                 market index such as the Bond Buyer 20 Index, the Merrill
                 Lynch 500 Municipal Market Index or the Lehman Brothers
                 Municipal Bond Index. Comparative performance information may
                 also be used from time to time in advertising or marketing
                 the Fund's shares, including data from Lipper Analytical
                 Services, Inc., Morningstar, Inc. and other industry
                 publications.

DISTRIBUTIONS AND TAXES
                    

    
                 HOW THE FUND PAYS DIVIDENDS     
The Fund pays    The Fund will pay monthly dividends to shareholders at a
monthly          level rate that reflects the past and projected net income of
dividends [/R]   the Fund and that results, over time, in the distribution of
                 substantially all of the Fund's net income. Net income of the
                 Fund consists of all interest income accrued on its portfolio
                 less all expenses of the Fund accrued daily. To maintain a
                 more stable monthly distribution, the Fund may from time to
                 time distribute less than the entire amount of net income
                 earned in a particular period. This undistributed net income
                 would be available to supplement future distributions, which
                 might otherwise have been reduced by a decrease in the Fund's
                 monthly net income due to fluctuations in investment income
                 or expenses. As a result, the distributions paid by the Fund
                 for any particular monthly period may be more or less than
                 the amount of net income actually earned by the Fund during
                 such period. Undistributed net income is included in the
                 Fund's net asset value and, correspondingly, distributions
                 from previously undistributed net income are deducted from
                 the Fund's net asset value. It is not expected that this
                 dividend policy will impact the management of the Fund's
                 portfolio.
 
                 Dividends paid by the Fund with respect to each class of
                 shares will be calculated in the same manner and at the same
                 time, and will be paid in the same amount except that
                 different distribution and service fees and any other expense
                 relating to a specific class of shares will be borne
                 exclusively by that class. As a result, dividends per share
                 will vary among the Fund's classes.
 
                 The Fund will declare dividends on the 9th of each month (or
                 if the 9th is not a business day, on the immediately
                 preceding business day), payable to shareholders of record as
                 of the close of business on that day. This distribution
                 policy is subject to change, however, by the Board of
                 Trustees of the Fund without prior notice to or approval by
                 shareholders. Dividends will be paid on the first business
                 day of the following month and are reinvested in additional
                 shares of the Fund at net asset value unless you have elected
                 that your dividends be paid in cash. Net realized capital
                 gains, if any, will be paid not less frequently than annually
                 and will be reinvested at net asset value in additional
                 shares of the Fund unless you have elected to receive capital
                 gains distributions in cash.
                    
                 TAX MATTERS     
                 The following federal tax discussion is intended to provide
                 you with an overview of the impact of federal income tax
                 provisions on the Fund or its shareholders. These tax
                 provisions are subject to change by legislative or
                 administrative action, and any changes may be applied
                 retroactively. Because the Fund's taxes are a complex

                                      NUVEEN MUNICIPAL BOND FUND PROSPECTUS     
                                                                  
                                                               JULY 1, 1996     
                 matter, you should consult your tax adviser for more detailed
                 information concerning the taxation of the Fund and the
                 federal, state and local tax consequences to Fund
                 shareholders.
 
                 The Fund intends to qualify, as it has in prior years, under
Income           Subchapter M of the Internal Revenue Code of 1986, as amended
dividends are    (the "Code"), for tax treatment as a regulated investment
free from        company. In order to qualify for treatment as a regulated
regular          investment company, the Fund must satisfy certain
federal income   requirements relating to the sources of its income,
tax              diversification of its assets and distribution of its income
                 to shareholders. As a regulated investment company, the Fund
                 will not be subject to federal income tax on the portion of
                 its net investment income and net realized capital gains that
                 is currently distributed to shareholders. The Fund also
                 intends to satisfy conditions that will enable it to pay
                 "exempt-interest dividends" to its shareholders. This means
                 that you will not be subject to regular federal income tax on
                 Fund dividends you receive from income on Municipal
                 Obligations.
 
                 Your share of the Fund's taxable income, if any, from income
                 on taxable temporary investments and net short-term capital
                 gains, will be taxable to you as ordinary income. If the 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. Distributions, if
                 any, of net long-term capital gains are taxable as long-term
                 capital gains, regardless of the length of time you have
                 owned Fund shares. You are required to pay tax on all taxable
                 distributions even if these distributions are automatically
                 reinvested in additional Fund shares. Certain distributions
                 paid by a Fund in January of a given year may be taxable to
                 shareholders as if received the prior December 31. As long as
                 the Fund qualifies as a regulated investment company under
                 the Code, distributions will not qualify for the dividends
                 received deduction for corporate shareholders. Investors
                 should consider the tax implications of buying shares
                 immediately prior to a distribution. Investors who purchase
                 shares shortly before the record date for a distribution will
                 pay a per share price that includes the value of the
                 anticipated distribution and will be taxed on the
                 distribution (unless it is exempt from tax) even though the
                 distribution represents a return of a portion of the purchase
                 price.

                 If in any year the 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 taxable income for that year, and the
                 entire amount of your distributions would be taxable as
                 ordinary income.
 
                 The Code does not permit you to deduct the interest on
                 borrowed monies used to purchase or carry tax-free
                 investments, such as Fund shares. Under Internal Revenue
                 Service rules, the purchase of Fund shares may be considered
                 to have been made with borrowed monies even though those
                 monies are not directly traceable to the purchase of those
                 shares.
 
                 Because the net asset value of the Fund's shares includes net
                 tax-exempt interest earned by the Fund but not yet declared
                 as an exempt-interest dividend, each time an exempt-interest
                 dividend is declared, the net asset value of the Fund's
                 shares will decrease in an amount equal to the amount of the
                 dividend. Accordingly, if you redeem Fund shares immediately
                 prior to or on the record date of a monthly exempt-interest
                 dividend, you may realize a taxable gain even though a
                 portion of the redemption proceeds may represent your pro
                 rata share of undistributed tax-exempt interest earned by the
                 Fund.
 
                 The redemption or exchange of Fund shares normally will
                 result in capital gain or loss to shareholders. Any loss you
                 may realize on the redemption or exchange of Fund shares held
                 for six months or less will be disallowed to the extent of
                 any distribution of exempt-interest dividends received on
                 these shares and will be treated as a long-term capital loss
                 to the extent of any distribution of long-term capital gain
                 received on these shares.
 
                 If you receive social security or railroad retirement
                 benefits you should note that tax-exempt income is taken into
                 account in calculating the amount of these benefits that may
                 be subject to federal income tax.
 
                 The Fund may invest in private activity bonds, the interest
                 on which is not exempt from federal income tax to
                 "substantial users" of the facilities financed by these bonds
                 or "related persons" of such substantial users. Therefore,
                 the Fund may not be an appropriate investment for you if you
                 are considered either a substantial user or a related person.

                 The Fund may invest up to 20% of its net assets in AMT Bonds,
                 the interest on which is a specific tax preference item for
                 purposes of computing the alternative minimum tax on
                 corporations and individuals. If your tax liability is
                 determined under the alternative minimum tax, you will be
                 taxed on your share of the Fund's exempt-interest dividends
                 that were paid from income earned on AMT Bonds. In addition,
                 the alternative minimum taxable income for corporations is
                 increased by 75% of the difference between an alternative
                 measure of income ("adjusted current earnings") and the
                 amount otherwise determined to be alternative minimum taxable
                 income. Interest on all Municipal Obligations, and therefore
                 all distributions by the Fund that would otherwise be tax
                 exempt, is included in calculating a corporation's adjusted
                 current earnings.
 
                 The Fund is 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
                 Fund their correct taxpayer identification number (in the
                 case of individuals, their social security number) and
                 certain certifications, or who are otherwise subject to back-
                 up withholding.
 
                 Each January, the Fund will notify you of the amount and tax
                 status of Fund distributions for the preceding year.

NET ASSET VALUE     
       
                 Net asset value of the shares of the Fund will be determined
Net asset        separately for each class of shares. The net asset value per
value is         share of a class of shares will be computed by dividing the
calculated       value of the Fund's assets attributable to the class, less
daily            the liabilities attributable to the class, by the total
                 number of shares of the class outstanding. The net asset
                 value per share is expected to vary among Class A Shares,
                 Class C Shares and Class R Shares, principally due to the
                 differences in sales charges, distribution and service fees
                 and other class expenses borne by each class.
                    
                 Net asset value will be determined by The Chase Manhattan
                 Bank, N.A., the Fund's custodian, as of 4:00 p.m. Eastern
                 Time on each day the New York Stock Exchange is normally open
                 for trading. In determining net asset value, the custodian
                 uses the valuations of portfolio securities furnished by a
                 pricing service approved by the Board of Trustees. The
                 pricing service values portfolio securities at the mean
                 between the quoted bid and asked prices or the yield
                 equivalent when quotations are readily available. Securities
                 for which quotations are not readily available (which are
                 expected to constitute a majority of the securities held by
                 the Fund) are valued at fair value as determined by the
                 pricing service using methods that 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 securities 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 Fund under the general supervision of its Board of
                 Trustees.

                 The Fund is an open-end diversified management investment
Organization     company under the Investment Company Act of 1940. The Fund
                 was originally incorporated in Maryland on October 8, 1976
                 and reorganized as a Massachusetts business trust on June 12,
                 1995. The Board of Trustees is authorized to issue an
                 unlimited number of shares, $.10 par value, divided into
                 three classes of shares designated as Class A Shares, Class C
                 Shares and Class R Shares. Each class of shares represents an
                 interest in the same portfolio of investments of the Fund.
                 Each class of shares has equal rights as to voting,
                 redemption, dividends and liquidation, except that each bears
                 different class expenses, including different distribution
                 and service fees, and each has exclusive voting rights with
                 respect to any distribution or service plan applicable to its
                 shares. There are no conversion, preemptive or other
                 subscription rights, except that Class C Shares automatically
                 convert into Class A Shares, as described above. The Board of
                 Trustees has the right to establish additional series of the
                 Fund and classes of shares in the future, to change those
                 series or classes and to determine the preferences, voting
                 powers, rights and privileges thereof.
 
                 The Fund is not required and does not intend to hold annual
                 meetings of shareholders. Shareholders owning more than 10%
                 of the outstanding shares of the Fund have the right to call
                 a special meeting to remove Trustees or for any other
                 purpose.

                 The Fund is an entity of the type commonly known as a
                 "Massachusetts business trust." Under Massachusetts law,
                 shareholders of such 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 Fund and requires that notice of this
                 disclaimer be given in each agreement, obligation or
                 instrument entered into or executed by the Fund or the
                 Trustees. The Declaration of Trust further provides for
                 indemnification out of the assets and property of the Fund
                 for all loss and expense of any shareholder held personally
                 liable for the obligations of the Fund. 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 Fund itself was
                 unable to meet its obligations. The Fund believes the
                 likelihood of these circumstances is remote.

YIELD TABLES                                                   JULY 1, 1996 [/R]
                    
                 TAXABLE EQUIVALENT YIELD TABLES AND THE EFFECT OF TAXES AND
                 INTEREST RATES ON INVESTMENTS     
                    
                 The following tables show the combined effects for
                 individuals of federal, state and local (if applicable)
                 income taxes on:     
                    
                 . what you would have to earn on a taxable investment to
                   equal a given tax-free yield; and     
                    
                 . the amount that those subject to a given combined tax rate
                   would have to put into a tax-free investment in order to
                   generate the same after-tax income as a taxable investment.
                          
                 These tables are for illustrative purposes only and are not
                 intended to predict the actual return you might earn on a
                 Fund investment. The Fund occasionally may advertise its
                 performance in similar tables using other current tax rates
                 than those shown here. The rates used in these tables have
                 been rounded to the nearest one-half of one percent. They are
                 based upon published 1996 marginal federal tax rates and do
                 not take into account changes in tax rates that are proposed
                 from time to time. A taxpayer's marginal tax rate is affected
                 by both his taxable income and his adjusted gross income. The
                 tables assume taxpayers are not subject to any alternative
                 minimum taxes and deduct any state income taxes paid on their
                 federal income tax returns. They also reflect the effect of
                 the current federal tax limitations on itemized deductions
                 and personal exemptions, which were designed to phase out
                 certain benefits of these deductions for higher income
                 taxpayers. These limitations are subject to certain maximums,
                 which depend on the number of exemptions claimed and the
                 total amount of the taxpayer's itemized deductions. For
                 example, the limitation on itemized deductions will not cause
                 a taxpayer to lose more than 80% of his allowable itemized
                 deductions, with certain exceptions. The tax rates shown here
                 may be higher or lower than your actual tax rate.

                 FUNDAMENTAL POLICIES AND INVESTMENT PORTFOLIO
 
FUNDAMENTAL POLICIES
The investment objective and certain fundamental investment policies of the
Fund are described in the Prospectus. The Fund, as a fundamental policy, may
not, without the approval of the holders of a majority of the shares of the
Fund:
 
(1) Invest in securities other than Municipal Obligations and temporary invest-
ments, as those terms are defined in the Prospectus;
   
(2) Invest more than 5% of its total assets in securities of any one issuer,
except that this limitation shall not apply to securities of the United States
Government, its agencies and instrumentalities;     
 
(3) Borrow money, except for temporary or emergency purposes and not for in-
vestment purposes and then only in an amount not exceeding 5% of the value of
the Fund's total assets at the time of borrowing;
   
(4) Pledge, mortgage or hypothecate its assets, except that, to secure
borrowings permitted by subparagraph (3) above, the Fund 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;
 
(6) Underwrite any issue of securities;
 
(7) Purchase or sell real estate, but this shall not prevent the Fund from in-
vesting in Municipal Obligations secured by real estate or interests therein;
 
(8) Purchase or sell commodities or commodities contracts or oil, gas or other
mineral exploration or development programs;
 
(9) Make loans, other than by entering into repurchase agreements and through
the purchase of Municipal Obligations or temporary investments in accordance
with the Fund's investment objective, policies and limitations;
 
(10) Make short sales of securities or purchase any securities on margin, ex-
cept for such short-term credits as are necessary for the clearance of transac-
tions;
 
(11) Write or purchase puts, calls, straddles, spreads or any combination
thereof;
 
(12) Invest more than 5% of its total assets in securities of unseasoned is-
suers which, together with their predecessors, have been in operation for less
than three years;
 
(13) Invest more than 10% of its total assets in securities that the Fund is
restricted from selling to the public without registration under the Securities
Act of 1933; or
 
(14) 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 Fund, or those
officers and directors of Nuveen Advisory Corp. ("Nuveen Advisory"), who indi-
vidually own beneficially more than 1/2 of 1% of the outstanding securities of
such issuer, together own beneficially more than 5% of such outstanding securi-
ties.

<PAGE>
 
For the purpose of applying the limitations set forth in paragraphs (2) and
(12) 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 secu-
rities 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 obli-
gation of a superior or unrelated governmental entity or other entity (other
than a bond insurer), it shall also be included in the computation of securi-
ties 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. It is a fundamental policy of the Fund, which cannot be
changed without the approval of the holders of a majority of shares, that the
Fund will not hold securities of a single bank, including securities backed by
a letter of credit of such bank, if such holdings would exceed 10% of the total
assets of the Fund.
   
With respect to temporary investments, in addition to the foregoing limita-
tions, the Fund will not purchase securities (other than securities of the U.S.
Government, its agencies and instrumentalities) if, as a result of such pur-
chase, more than 25% of the Fund's total assets would be invested in any one
industry nor enter into a repurchase agreement if, as a result thereof, more
than 10% of its assets would be subject to repurchase agreements maturing in
more than seven days.     
 
The foregoing restrictions and limitations, as well as the 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 un-
less 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 ob-
jective of the Fund, cannot be changed without approval by holders of a "major-
ity of the Fund's outstanding voting shares." As defined in the Investment Com-
pany 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.
 
PORTFOLIO SECURITIES
As described in the Prospectus, the 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 ob-
ligations issued by states, cities and local authorities to obtain funds for
various public purposes, including construction of a wide range of public fa-
cilities such as airports,
 
                                                                               3
<PAGE>
 
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 the 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") or Standard and
Poor's Corporation ("S&P"), (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 or S&P, except that the Fund
may not invest more than 10% of its net assets in unrated bonds and (3) tempo-
rary investments as described below, the income from which may be subject to
federal income tax.
 
As described in the Prospectus, the 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 prop-
erty in the event of foreclosure might prove difficult. The Fund will seek to
minimize the special risks associated with such securities by not investing
more than 10% of its assets in lease obligations that contain non-appropria-
tion clauses, and by only investing in those nonappropriation leases where (1)
the nature of the leased equipment or property is such that its ownership or
use is essential to a governmental function of the municipality, (2) the lease
payments will commence amortization of principal at an early date resulting in
an average life of seven years or less for the lease obligation, (3) appropri-
ate covenants will be obtained from the municipal obligor prohibiting the sub-
stitution or purchase of similar equipment if lease payments are not appropri-
ated, (4) the lease obligor has maintained good market acceptability in the
past, (5) the investment is of a size that will be attractive to institutional
investors, and (6) the underlying leased equipment has elements of portability
and/or use that enhance its marketability in the event foreclosure on the un-
derlying equipment were ever required. Lease obligations provide a premium in-
terest rate which along with regular amortization of the principal may make
them attractive for a portion of the assets of the Fund.
 
Obligations of issuers of Municipal Obligations are subject to the provisions
of bankruptcy, insolvency and other laws affecting the rights and remedies of
creditors, such as the Federal Bankruptcy Reform Act of 1978. In addition, the
obligations of such issuers may become subject to the laws enacted in the fu-
ture by Congress, state legislatures or referenda extending the time for pay-
ment of principal and/or interest, or imposing other constraints upon enforce-
ment 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 Fund will make changes in its 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 Fund may also engage to a limited extent in
short-term trading consistent with its investment objective. Securities may be
sold in anticipation of market decline or purchased in anticipation of market
rise and later sold, but the Fund will not engage in trading solely to recog-
nize a gain. 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 rela-
tionship between the two securities. The Fund may make changes in its invest-
ment portfolio in order to limit its exposure to changing market conditions.
Changes in the Fund's investments are known as "portfolio turnover." While it
is impossible to predict future portfolio turnover rates, the Fund's annual
portfolio turnover rate is generally not expected to exceed 35%. However, the
Fund reserves the right to make changes in its investments whenever it deems
such action advisable, and therefore, the Fund's annual portfolio turnover
rate may exceed 35% in particular years depending upon market conditions. The
Fund's portfolio turnover rate for each of the fiscal years ended February 29,
1996, and February 28, 1995 was 17%.     
 
WHEN-ISSUED SECURITIES
As described in the Prospectus, the Fund may purchase and sell Municipal Obli-
gations 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 obliga-
tion 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 securi-
ties 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 the Fund makes the commitment to pur-
chase 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 the Fund
makes the commitment to sell a Municipal Obligation on a delayed delivery ba-
sis, 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 Fund will maintain designated readily marketable assets at least
equal in value to commitments to purchase when-issued or delayed delivery se-
curities, such assets to be segregated by the Custodian specifically for the
settlement of such commitments. The Fund will only make commitments to pur-
chase Municipal Obligations on a when-issued or delayed delivery basis with
the intention of actually acquiring the securities, but the Fund reserves the
right to sell these securities before the settlement date if it is deemed ad-
visable. If a when-issued security is sold before delivery any gain or loss
would not be tax-exempt. A Fund commonly engages in when-issued transactions
in order to purchase or sell newly-issued Municipal Obligations, and may en-
gage in delayed delivery transactions in order to manage its operations more
effectively.

TEMPORARY INVESTMENTS
The Prospectus discusses briefly the ability of the Fund to invest a portion of
its assets in federally tax-exempt or taxable "temporary investments." Tempo-
rary investments will not exceed 20% of the Fund's assets except when made for
defensive purposes. The Fund will invest only in taxable temporary investments
that are either U.S. Government securities or are rated within the highest
grade by Moody's or S&P, and mature within one year from the date of purchase
or carry a variable or floating rate of interest.
 
The Fund may invest in the following federally tax-exempt temporary invest-
ments:
 
Bond Anticipation Notes (BANs) are usually general obligations of state and lo-
cal governmental issuers which are sold to obtain interim financing for pro-
jects that will eventually be funded through the sale of long-term debt obliga-
tions 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 mar-
ket 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 fi-
nance 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 delin-
quencies, 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 obliga-
tions 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 in-
terest on RANs.
 
Construction Loan Notes are issued to provide construction financing for spe-
cific 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 there-
from. Maturities of municipal paper generally will be shorter than the maturi-
ties of TANs, BANs or RANs. There is a limited secondary market for issues of
municipal paper.
 
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
 
6
<PAGE>
 
such other types of notes to the extent permitted under its investment objec-
tive, policies and limitations. Such notes may be issued for different purposes
and may be secured differently from those mentioned above.
 
The Fund 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 estab-
lished as instrumentalities of the United States Government to supervise and
finance certain types of activities. These agencies include, but are not lim-
ited 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 di-
rect 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 sup-
ported 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 inter-
est bearing instrument with a specific maturity. CDs are issued by banks in ex-
change 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 Fund 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 inter-
est.
 
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 the 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 Fund will only enter into
 
                                                                               7
<PAGE>
 
repurchase agreements with dealers, domestic banks or recognized financial in-
stitutions that in the opinion of Nuveen Advisory present minimal credit risk.
The risk to the Fund 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 de-
clines there is a risk of loss of both principal and interest. In the event of
default, the collateral may be sold but the Fund might incur a loss if the
value of the collateral declines, and might incur disposition costs or experi-
ence delays in connection with liquidating the collateral. In addition, if
bankruptcy proceedings are commenced with respect to the seller of the securi-
ty, realization upon the collateral by the Fund may be delayed or limited.
Nuveen Advisory will monitor the value of collateral at the time the transac-
tion is entered into and at all times subsequent during the term of the repur-
chase agreement in an effort to determine that the value always equals or ex-
ceeds 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. The Fund will not invest more than 10% of its assets in re-
purchase agreements maturing in more than seven days.
 
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 quali-
ty." 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 ele-
ments make long-term risks appear somewhat larger than in Aaa rated Municipal
Obligations. The Aaa and Aa rated Municipal Obligations comprise what are gen-
erally 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 obliga-
tions (i.e., they are neither highly protected nor poorly secured). Such bonds
lack outstanding investment characteristics and in fact have speculative char-
acteristics as well. Moody's bond rating symbols may contain numerical modifi-
ers 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 an extremely strong capacity to pay
principal and interest. The rating of AA indicates that capacity to pay princi-
pal 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 prin-
cipal and interest. Whereas such bonds normally exhibit adequate protection pa-
rameters, adverse economic conditions are more likely to lead to a weakened ca-
pacity to pay principal and interest for bonds in this category than for bonds
in the A category.

<PAGE>
 
The "Other Corporate Obligations" category of temporary investments are corpo-
rate (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 the Fund, an issue may cease to be rated or its
rating may be reduced below the minimum required for purchase. Neither event
requires the elimination of such obligation from the Fund's portfolio, but
Nuveen Advisory will consider such an event in its determination of whether the
Fund should continue to hold such obligation.
 
                                   MANAGEMENT
   
The management of the Fund, including general supervision of the duties per-
formed for the Fund under the Investment Management Agreement, is the responsi-
bility of its Board of Trustees. The Trust currently has six trustees, two of
whom are "interested persons" (as the term "interested person" is defined in
the Investment Company Act of 1940) and four of whom are "disinterested per-
sons." The names and business addresses of the trustees and officers of the
Fund and their principal occupations and other affiliations during the past
five years are set forth below, with those trustees who are "interested per-
sons" of the Fund indicated by an asterisk.

Each trustee who is not affiliated with Nuveen or Nuveen Advisory receives a
$45,000 annual retainer for serving as a director or trustee of all funds for
which Nuveen Advisory serves as investment adviser and a $1,000 fee per day
plus expenses for attendance at all meetings held on a day on which a regularly
scheduled Board meeting is held, a $1,000 fee per day plus expenses for atten-
dance in person or a $500 fee per day plus expenses for attendance by telephone

             INVESTMENT ADVISER AND INVESTMENT MANAGEMENT AGREEMENT
 
Nuveen Advisory Corp. acts as investment adviser for and manages the investment
and reinvestment of the assets of the Fund. Nuveen Advisory also administers
the Fund's business affairs, provides office facilities and equipment and cer-
tain clerical, bookkeeping and administrative services, and permits any of its
officers or employees to serve without compensation as directors or officers of
the Fund if elected to such positions. See "Management of the Fund" in the Pro-
spectus.
 
Pursuant to an investment management agreement between Nuveen Advisory and the
Fund, the Fund has agreed to pay an annual management fee at the rates set
forth below:

For the next $1 billion      .4500 of 1%
For assets over $2 billion   .4250 of 1%
</TABLE>
   
Nuveen Advisory will waive all or a portion of its management fee or reimburse
certain expenses of the Fund in order to prevent total operating expenses (in-
cluding Nuveen Advisory's fee, but excluding interest, taxes, fees incurred in
acquiring and disposing of portfolio securities, any asset-based distribution
or service fees and, to the extent permitted, extraordinary expenses) in any
fiscal year from exceeding .75 of 1% of the average daily net asset value of
any class of shares of the Fund. The net management fee for the fiscal year
ended February 29, 1996 amounted to $12,797,372, after giving effect to fee
waivers and expense reimbursements of $4,313. The net management fees for the
fiscal years ended February 28, 1995 and 1994, amounted to $11,932,164 and
$11,645,399, respectively. As discussed in the Prospectus, subject to the ex-
pense limitations of the Investment Management Agreement, the Fund is responsi-
ble for payment of certain of the costs and expenses of its operations.     
   
Nuveen Advisory is a wholly owned subsidiary of John Nuveen & Co. Incorporated
("Nuveen"), the Fund's principal underwriter. Founded in 1898, Nuveen is the
oldest and largest investment banking firm specializing in the underwriting and
distribution of tax-exempt securities and maintains the largest research de-
partment in the investment banking community devoted exclusively to the analy-
sis of municipal securities. 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
$31 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-ex-
empt funds and trusts. Nuveen is a subsidiary of The John Nuveen Company which,
in turn, is approximately 80% 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.     
 
Nuveen Advisory's portfolio managers call upon the resources of Nuveen's Re-
search Department, the largest in the investment banking industry devoted ex-
clusively to tax-exempt securities. Nuveen's Research Department was selected
in 1994 by Research & Ratings Review, a municipal industry publication,
 
                                                                              13
<PAGE>
 
   
as one of the leading research teams in the municipal industry, based on an ex-
tensive industry-wide poll of portfolio managers, department heads and bond
buyers. The Nuveen Research Department reviews more than $100 billion in tax-
exempt bonds every year.     
   
The Fund, the other Nuveen Funds, the Adviser, 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 the 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 ob-
tained elsewhere. Portfolio securities will not be purchased from Nuveen or its
affiliates except in compliance with the Investment Company Act of 1940.
 
The Fund since its inception has effected all portfolio transactions on a prin-
cipal (as opposed to an agency) basis and, accordingly, has not paid any bro-
kerage 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 Fund 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 supple-
mentary to Nuveen Advisory's own research efforts, the receipt of research in-
formation 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 Fund, the policies and practices of Nuveen Advisory in this re-
gard 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 ac-
counts and investment companies for other clients, which may have investment
objectives similar to the Fund. Subject to applicable laws and regulations,
Nuveen Advisory will attempt to allocate equitably portfolio transactions among
the Fund and the portfolios of its other clients purchasing or selling securi-
ties whenever decisions are made to purchase or sell securities by the 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
 
14
<PAGE>
 
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 the 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 ex-
posure to simultaneous transactions.
 
Under the Investment Company Act of 1940, the Fund 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 Munici-
pal Obligations purchased by the Fund, the amount of Municipal Obligations
which may be purchased in any one issue and the assets of the Fund which may be
invested in a particular issue. In addition, purchases of securities made pur-
suant 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 per-
sons of the Fund.
 
                                NET ASSET VALUE
   
As stated in the Prospectus, the net asset value of the shares of the Fund will
be determined separately for each class of the Fund's shares by The Chase Man-
hattan Bank, N.A., the Fund's custodian, as of 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 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 Fund, the Fund's custodian utilizes the
valuations of portfolio securities furnished by a pricing service approved by
the directors. The pricing service values portfolio securities at the mean be-
tween the quoted bid and asked price or the yield equivalent when quotations
are readily available. Securities for which quotations are not readily avail-
able (which constitute a majority of the securities held by the Fund) are val-
ued at fair value as determined by the pricing service using methods which in-
clude 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 securities representatives; and general market conditions. The
pricing service may employ electronic data processing techniques and/or a ma-
trix system to determine valuations. The procedures of the pricing service and
its valuations are reviewed by the officers of the Fund under the general su-
pervision of the Board of Trustees.
 
                                                                              15

                                  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, Washington, D.C., counsel to the
Fund.
 
As described in the Prospectus, the 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 invest-
ment company, the Fund must satisfy certain requirements relating to the source
of its income, diversification of its assets, and distributions of its income
to shareholders. First, the 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 invest-
ing in such stock or securities (the "90% gross income test"). Second, the 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, the 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 secu-
rities 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 regu-
lated investment companies) or two or more issuers controlled by the Fund and
engaged in the same, similar or related trades or businesses.
   
As a regulated investment company, the Fund will not be subject to federal in-
come 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, tax-
able interest, taxable original issue discount and market discount income, in-
come 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) . The 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 the 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 the 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 undistrib-
uted amount, and (ii) will be entitled to credit their proportionate shares of
the tax paid by the 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 in-
come. The 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.     
 
16
<PAGE>
 
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.
 
The 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 re-
ceived by the Fund, as exempt-interest dividends. Shareholders receiving ex-
empt-interest dividends will not be subject to regular federal income tax on
the amount of such dividends. Insurance proceeds received by the Fund under any
insurance policies in respect of scheduled interest payments on defaulted Mu-
nicipal Obligations will be excludable from federal gross income under Section
103(a) of the Code. In the case of non-appropriation by a political subdivi-
sion, however, there can be no assurance that payments made by the insurer rep-
resenting interest on "non-appropriation" lease obligations will be excludable
from gross income for federal income tax purposes. See "Fundamental Policies
and Investment Portfolio; Portfolio Securities."
 
Distributions by the Fund of net interest received from certain taxable tempo-
rary investments (such as certificates of deposit, commercial paper and obliga-
tions of the U.S. Government, its agencies and instrumentalities) and net
short-term capital gains realized by the Fund, if any, will be taxable to
shareholders as ordinary income whether received in cash or additional
shares./1/ If the Fund purchases a Municipal
       
Obligation at a market discount, any gain realized by the Fund upon sale or re-
demption 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 real-
ized in excess of the market discount will be treated as capital gains. Any net
long-term capital gains realized by the 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 the Fund.
Distributions by the Fund that do not constitute ordinary income dividends, ex-
empt-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 the Fund engages in hedging transactions involving financial futures and op-
tions, these transactions will be subject to special tax rules, the effect of
which may be to accelerate income to the Fund, defer the Fund's losses, cause
adjustments in the holding periods of the 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.     
- --------
/1/If the Fund has both tax-exempt and taxable income, it will use the "average
   annual" method for determining the designated percentage that is taxable in-
   come 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 ap-
   plied uniformly to all distributions made during the Fund's taxable year.
   The percentage of income designated as tax-exempt for any particular distri-
   bution may be substantially different from the percentage of the Fund's in-
   come that was tax-exempt during the period covered by the distribution.
 
                                                                              17
<PAGE>
 
Because the taxable portion of the 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 divi-
dends received deductions for corporations.
 
Prior to purchasing shares in the Fund, the impact of dividends or distribu-
tions 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 reduc-
ing 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, divi-
dends 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 the Fund (and received
by the shareholders) on December 31.
 
The redemption or exchange of the shares of the 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 corpora-
tions 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 deduc-
tions 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 redemp-
tion or exchange of such shares within 90 days after their purchase to the ex-
tent shares of a Fund or another fund are subsequently acquired without payment
of a sales load pursuant to the reinvestment or exchange privilege. Any disre-
garded portion of such load 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 the Fund held for six
months or less are disallowed to the extent of any distribution of exempt-in-
terest 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 dis-
tributions of long-term capital gains made with respect to such shares. In ad-
dition, no loss will be allowed on the redemption or exchange of shares of the
Fund if the shareholder purchases other shares of the Fund (whether through re-
investment of distributions or otherwise) or the Shareholder acquires or enters
into a contract or option to acquire securities that are substantially identi-
cal to shares of the 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
 
18
<PAGE>
 
treatment of the portion of the sales or redemption proceeds equal to the ac-
crued tax-exempt interest as taxable gain (to the extent the redemption or ex-
change 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, the 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 real-
ized capital losses for the prior year that was not distributed during such
year and on which the Fund paid no federal income tax. For purposes of the ex-
cise 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 Fund intends 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 the 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 the Fund must meet in order to qualify under
Subchapter M in any year is that less than 30% of its gross income must be de-
rived from the sale or other disposition of securities and certain other assets
held for less than three months.
 
Because the Fund may invest in private activity bonds, the interest on which is
not federally tax-exempt to persons who are "substantial users" of the facili-
ties financed by such bonds or "related persons" of such "substantial users,"
the Fund may not be an appropriate investment for shareholders who are consid-
ered either a "substantial user" or a "related person" within the meaning of
the Code. For additional information, investors should consult their tax advis-
ers before investing in the Fund.
 
Federal tax law imposes an alternative minimum tax with respect to both corpo-
rations 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 hos-
pitals) is included as an item of tax preference in determining the amount of a
taxpayer's alternative minimum taxable income. To the extent that the Fund re-
ceives income from Municipal Obligations subject to the alternative minimum
tax, a portion of the dividends paid by it, although otherwise exempt from fed-
eral income tax, will be taxable to shareholders to the extent that their tax
liability is determined under the alternative minimum tax regime. The Fund 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 in-
creased by 75% of the difference between an alternative measure of income ("ad-
justed current earnings") and the amount otherwise
 
                                                                              19
<PAGE>
      
determined to be the alternative minimum taxable income. Interest on all Mu-
nicipal Obligations, and therefore all distributions by the Fund 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 the 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 pur-
chase or carry shares of the 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 the 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 Fund is required in certain circumstances to withhold 31% of taxable divi-
dends and certain other payments paid to non-corporate holders of shares who
have not furnished to the Fund their correct taxpayer identification number
(in the case of individuals, their social security number) and certain certi-
fications, or who are otherwise subject to back-up 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 adminis-
trative 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 Fund and the
income tax consequences to its shareholders.
 
                            PERFORMANCE INFORMATION
   
As explained in the Prospectus, the historical investment performance of the
Fund 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 invest-
ment 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, accord-
ing to the following formula:
 
 
<TABLE>
 <C>   <C> <C>             <C> <S>
 Yield =   2[(a-b+1)/6/-1]
           cd
</TABLE>
 
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
 
20
<PAGE>
 
   
the period. In the case of Class A shares, the maximum offering price includes
the current maximum sales charge of 4.50%.     
   
In computing yield, the Fund follows certain standardized accounting practices
specified by SEC rules. These practices are not necessarily consistent with
those that the Fund uses to prepare its 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 the Fund's
financial statements. Yields for Class A Shares, Class C Shares and Class R
Shares for the 30-day period ended February 29, 1996 were 4.48%, 3.94% and
4.93%, respectively.     
   
Taxable equivalent yield is computed by dividing that portion of the yield
which is tax-exempt by 1 minus the stated federal income tax rate and adding
the result to that portion, if any, of the yield that is not tax exempt. Based
upon (1) the 1995 maximum marginal federal income tax rate of 39.6% and (2) the
previously quoted yield for the 30-day period ended February 29, 1996, the tax-
able equivalent yields for Class A Shares, Class C Shares and Class R Shares
for that period were 7.42%, 6.52% and 8.16%, respectively.     
 
For additional information concerning taxable equivalent yields, see the Tax-
able Equivalent Yield Tables in the Prospectus.
   
The Fund may from time to time in its advertising and sales materials report a
quotation of the 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 dis-
tribution rate differs from yield and total return and therefore is not in-
tended to be a complete measure of performance. Distribution rate may sometimes
be higher than yield 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 February 29, 1996, for Class A Shares, Class C
Shares and Class R Shares were 4.88%, 4.41% and 5.37%, respectively, assuming
the imposition of the maximum sales charge for Class A Shares of 4.50%.     
   
Average annual total return quotation is computed in accordance with a stan-
dardized 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 repre-
senting 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 in-
come and capital gains distributions have been reinvested in Fund shares at net
asset value on the reinvestment dates during the period. The Fund's average an-
nual return figures, including the effect of the current maximum sales charge
for Class A Shares, for the one-year, five-year and ten-year periods ended Feb-
ruary 29, 1996, and for the period from inception (on November 29, 1976 with
respect to the Class R Shares

*Not annualized because it relates to a period of less than one year.     
   
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 "redeem-
able 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 cumula-
tive total returns, including the effect of the maximum sales charge for Class
A Shares, for the one-year, five-year and ten-year periods ended February 29,
1996, and for the period from inception (on November 29, 1976 with respect to
the Class R Shares and on June 13, 1995 with respect to the Class A Shares and
Class C Shares) through February 29, 1996, respectively, were as follows:

Calculation of taxable equivalent total return is also not subject to a pre-
scribed formula. Taxable equivalent total return for a specific period is cal-
culated 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), cal-
culated as described above under the discussion of "taxable equivalent yield."
The resulting amount for the calendar year is then divided by the initial in-
vestment 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 1996, the annual taxable equivalent total returns for the one-year, five-

From time to time, the Fund may compare its risk-adjusted performance with
other investments that may provide different levels of risk and return. For ex-
ample, the Fund may compare its risk level, as measured by the variability of
its periodic returns, or its RISK-ADJUSTED TOTAL RETURN, with those of other
funds or groups of funds. Risk-adjusted total return would be calculated by ad-
justing each investment's total return to account for the risk level of the in-
vestment.
 
The Fund may also compare its TAX-ADJUSTED TOTAL RETURN with that of other
funds or groups of funds. This measure would take into account the tax-exempt
nature of exempt-interest dividends and the payment of income taxes on a fund's
distributions of net realized capital gains and ordinary income.
   
The risk level for a class of shares of the Fund, and any of the other invest-
ments used for comparison, would be evaluated by measuring the variability of
the investment's return, as indicated by the annualized standard deviation of
the investment's monthly returns over a specified measurement period (e.g.,
three years). An investment with a higher annualized standard deviation of
monthly returns would indicate that a fund had greater price variability, and
therefore greater risk, than an investment with a lower annualized standard de-
viation. The annualized standard deviation of monthly returns for the three
years ended February 29, 1996, for the Class R Shares of the Fund, was 4.07%.
       
THE RISK-ADJUSTED TOTAL RETURN for a class of shares of the Fund and for other
investments over a specified period would be evaluated by dividing (a) the re-
mainder of the investment's annualized three-year total return minus the
annualized total return of an investment in short-term tax-exempt securities
(essentially a risk-free return) over that period, by (b) the standard devia-
tion of the investment's monthly returns for the period. This ratio is some-
times referred to as the "Sharpe measure" of return. An investment with a
higher Sharpe measure would be regarded as producing a higher return for the
amount of risk assumed during the measurement period than an investment with a
lower Sharpe measure. The Sharpe measure, for the three-year period ended Feb-
ruary 29, 1996, for the Class R Shares of the Fund, was 0.646.     
 
Class A Shares of the Fund are sold at net asset value plus a current maximum
sales charge of 4.50% of the offering price. This current maximum sales charge
will typically be used for purposes of calculating performance figures even
though the maximum sales charge may have been different for portion of the mea-
surement period. Yield, returns and net asset value of each class of shares of
the Fund will fluctuate.
 
                                                                              23

Factors affecting performance include general market conditions, operating ex-
penses 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 Fund 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 Fund may also compare its 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"), Morn-
ingstar, Inc. ("Morningstar"), Wiesenberger Investment Companies Service ("Wie-
senberger") and CDA Investment Technologies, Inc. ("CDA") or similar indepen-
dent 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, av-
erage, year-by-year, or other types of total return and performance figures.
Any given performance quotation or performance comparison should not be consid-
ered as representative of the performance of the Fund for any future period.
 
There are differences and similarities between the investments which the Fund
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 Munic-
ipal 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, Morningstar, Wiesenberger and CDA are widely recognized mu-
tual fund reporting services whose performance calculations are based upon
changes in net asset value with all dividends reinvested and which do not in-
clude the effect of any sales charges. The market prices and yields of taxable
and tax-exempt bonds will fluctuate. The Fund primarily invests in investment
grade Municipal Obligations in pursuing its objective of as high a level of
current interest income which is exempt from federal income tax as is consis-
tent, in the view of the Fund's management, with preservation of capital.
 
The Fund may also compare its taxable equivalent total return performance to
the total return performance of taxable income funds such as treasury securi-
ties funds, corporate bond funds (either investment grade or high yield), or
Ginnie Mae funds. These types of funds, because of the character of their un-
derlying 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 mu-
nicipal bonds resulting from changes in market interest rates and are particu-
larly susceptible to volatility from credit changes. Ginnie Mae bonds are gen-
erally subject to less price volatility than municipal bonds from credit con-
cerns, 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
 
24
<PAGE>
 
U.S. Government, but Ginnie Maes of equivalent coupon and maturity are gener-
ally 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 REDEMPTIONOF FUND SHARES
   
As described in the Prospectus, the Fund has adopted a Flexible Pricing Pro-
gram which provides you with alternative ways of purchasing Fund shares based
upon your individual investment needs and preferences. You may purchase Class
A Shares at a price equal to their net asset value plus an up-front sales
charge.     
   
For information regarding the up-front sales charge on Class A shares, see the
table under "How to Buy Fund Shares" of the Prospectus. Set forth is an exam-
ple of the method of computing the offering price of the Class A shares of the
Fund. The example assumes a purchase on February 29, 1996 of Class A shares
from the Fund aggregating less than $50,000 subject to the schedule of sales
charges set forth in the Prospectus at a price based upon the net asset value
of the Class A shares.

You may purchase Class C Shares without any up-front sales charge at a price
equal to their net asset value, but subject to an annual distribution fee de-
signed to compensate Authorized Dealers over time for the sale of Fund shares.
Class C Shares are subject to a 1% contingent deferred sales charge for re-
demptions within 12 months of purchase. Class C Shares automatically convert
to Class A Shares six years after purchase. Both Class A Shares and Class C
Shares are subject to annual service fees, which are used to compensate Autho-
rized Dealers for providing you with ongoing account services. Under the Flex-
ible Sales Charge Program, all Fund shares outstanding as of June 13 1995,
have been designated as Class R Shares. Class R Shares are available for pur-
chase at a price equal to their net asset value only under certain limited
circumstances, or by specified investors, as described herein.     
   
Each class of shares represents an interest in the same portfolio of invest-
ments. 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 dis-
tribution or service plan applicable to its shares. In addition, the Class C
Shares are subject to a conversion feature, as described below. 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 the
Fund's classes of shares.     
   
Shareholders of each class will shares 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 dis-
tribution and service fees.     
 
                                                                             25

The Fund has special purchase programs under which certain persons may purchase
Class A Shares at reduced sales charges. One such program is available to mem-
bers of a "qualified group." An individual who is a member of a "qualified
group" may purchase Class A Shares of the Fund (or any other Nuveen Fund with
respect to which a sales charge is imposed), at the reduced sales charge appli-
cable to the group taken as whole. A "qualified group" is one which (i) has
been in existence for more than six months; (ii) has a purpose other than in-
vestment; (iii) has five or more participating members; (iv) has agreed to in-
clude sales literature and other materials related to the Fund in publications
and mailings to members; (v) has agreed to have its group administrator submit
a single bulk order and make payment with a single remittance for all invest-
ments in the Fund during each investment period by all participants who choose
to invest in the Fund; and (vi) has agreed to provide the Fund's transfer agent
with appropriate backup data for each participant of the group in a format
fully compatible with the transfer agent's processing system.
 
The "amount" of a share purchase by a participant in a group purchase program
for purposes of determining the applicable sales charge is (i) the aggregate
value of all shares of the Fund (and all other Nuveen Funds with respect to
which a sales charge is imposed) currently held by participants of the group,
plus (ii) the amount of shares currently being purchased.
   
Special Sales Charge Waivers. Class A Shares of the Funds 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 retired trustees of the Trust;     
   
 .  bona fide, full-time and retired employees of Nuveen and its affiliates, any
   parent company of Nuveen, and subsidiaries thereof, or their immediate fam-
   ily members (as defined below);     
   
 .  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;     
   
 .  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 through a mutual fund purchase program sponsored by a
   broker-dealer that offers a selected group of mutual funds either without a
   transaction fee or with an asset-based fee or a fixed fee that does not vary
   with the amount of the purchase. In order to qualify, such purchase program
   must offer a full range of mutual fund related services and shareholder ac-
   count servicing capabilities, including establishment and maintenance of
   shareholder accounts, addressing investor inquiries regarding account activ-
   ity and investment performances, processing of trading and dividend activity
   and generation of monthly account statements and year-end tax reporting; and
          
 .  registered investment advisers, certified financial planners and registered
   broker-dealers who in each case either charge periodic fees to their custom-
   ers for financial planning, investment advisory or asset management servic-
   es, or provide such services in connection with the establishment of an in-
   vestment account for which a comprehensive "wrap fee" charge is imposed.

The Fund may encourage registered representatives and their firms to help ap-
portion 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.
 
To help advisers and investors better understand and most efficiently use the
Fund to reach their investment goals, the Fund may advertise and create spe-
cific investment programs and systems. For example, this may include informa-
tion on how to use the Fund to accumulate assets for future education needs or
periodic payments such as insurance premiums. The Fund may produce software or
additional sales literature to promote the advantages of using the Fund to
meet these and other specific investor needs.
   
Exchanges of shares of the 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 pur-
chase on the following holidays: Martin Luther King's Birthday, Columbus Day
and Veterans Day.     
 
For more information on the procedure for purchasing shares of the 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 Fund pursuant
to a "best efforts" arrangement as provided by a distribution agreement with
the Nuveen Municipal Bond Fund, Inc., dated January 2, 1990, and assigned to
the Fund effective June 13, 1995 ("Distribution Agreement"). Pursuant to the
Distribution Agreement, the Fund appointed Nuveen to be its agent for the dis-
tribution of the Fund's shares on a continuous offering basis. Nuveen sells
shares to or through brokers, dealers, banks or other qualified financial in-
termediaries (collectively referred to as "Dealers"), or others, in a manner
consistent with the then effective registration statement of the Fund. Pursu-
ant to the Distribution Agreement, Nuveen, at its own expense, finances cer-
tain activities incident to the sale and distribution of the Fund's shares,
including printing and distributing of prospectuses and statements of addi-
tional information to other than existing shareholders, the printing and dis-
tributing 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 Fund's shares sold with an up-front sales
charge 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 Fund pursuant to Rule 12b-1 and described herein under "Distri-
bution and Service Plan." Nuveen receives any CDSCs imposed on redemptions of
Class C Shares redeemed within 12 months of purchase, but any such amounts as
to which a reinstatement privilege is not exercised are set off against and
reduce amounts otherwise payable to Nuveen pursuant to the distribution plan.
Nuveen also receives any CDSCs imposed on redemptions of certain Class A
Shares redeemed within 18 months of purchase.     
   
The aggregate amount of underwriting commissions with respect to the sale of
Fund shares and the amount thereof retained by Nuveen for the Fund's fiscal
years ended February 29, 1996, February 28, 1995 and February 28, 1994 were
$1,575, $316; $2,248, $467; and $5,703, $1,093, respectively. All figures are
to the nearest thousand.     
 
 
                                                                             27
<PAGE>
 
                    DISTRIBUTION AND SERVICE PLAN
 
The Fund has adopted a plan (the "Plan") pursuant to Rule 12b-1 under the In-
vestment Company Act of 1940, which provides that Class C Shares will be sub-
ject to an annual distribution fee, and that both Class A 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 C Shares under the Plan will be pay-
able to reimburse Nuveen for services and expenses incurred in connection with
the distribution of Class C Shares. These expenses include payments to Autho-
rized Dealers, including Nuveen, who are brokers of record with respect to the
Class C Shares, as well as, without limitation, expenses of printing and dis-
tributing 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 C Shares,
certain other expenses associated with the distribution of Class C Shares, and
any distribution-related expenses that may be authorized from time to time by
the Board of Directors.
 
The service fee applicable to Class A Shares and Class C Shares under the Plan
will be payable to Authorized Dealers in connection with the provision of ongo-
ing account services to shareholders. These services may include establishing
and maintaining shareholder accounts, answering shareholder inquiries and pro-
viding other personal services to shareholders.
 
The Fund may spend up to .25 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.
The Fund may spend up to .75 of 1% per year of the average daily net assets of
Class C Shares as a distribution fee and up to .25 of 1% per year of the aver-
age daily net assets of Class C Shares as a service fee under the Plan applica-
ble to Class C Shares. The .75 of 1% distribution fee will be reduced by the
amount of any CDSC imposed on the redemption of Class C Shares within 12 months
of purchase as to which a reinstatement privilege has not been exercised.
   
For the fiscal year ended February 29, 1996, 100% of service fees and distribu-
tion fees were paid out as compensation to Authorized Dealers. The amount of
compensation paid to Authorized Dealers for the fiscal year ended February 29,
1996 was $43,166.     
 
Under the Plan, the Fund will report quarterly to the Board of Trustees for its
review of 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 pay-
ment of any penalty, by a vote of a majority of the trustees who are not "in-
terested 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 directors 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 rea-
sonable business judgment and in light of their fiduciary duties under applica-
ble 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
 
28
<PAGE>
 
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 directors 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 Fund will be
committed to the discretion of the non-interested trustees then in office.

Dear
shareholder

[PHOTO OF RICHARD J. FRANKE APPEARS HERE]

"Over time, municipal bonds have proven to be a valuable and dependable
component of successful investment programs."

Since the beginning of the recovery in early 1995, we've enjoyed a welcome
rebound in the bond markets-a sharp contrast to 1994, which was one of the most
volatile periods in bond market history. In fact, 1995 unfolded as one of the
best years for bonds in a decade, as the bond market responded to a climate of
slowing economic growth and diminished inflationary pressure.

  The changing profile of the bond markets over the past two years reminds us
that weathering the ups and downs of the markets is a normal part of the
investment process. By maintaining a long-term perspective on your investments,
you can minimize the impact of short-term fluctuations and keep the focus on
achieving your goals. Municipal bond funds continue to play an integral role in
helping investors reach those goals, offering the attractive tax-free income and
solid total returns that they seek.

  Over the past year, we have kept our sights focused on successfully meeting
your fund's objectives. As of February 29, 1996, the current annual SEC yields
on offering price for R Shares were 4.93% for the Municipal Bond Fund and 5.00%
for the Insured Municipal Bond Fund. To match these yields, an investor in the
36% federal income tax bracket would have had to earn at least 7.70% and 7.81%,
respectively, on taxable alternatives.


                                       3
<PAGE>
 
  Reflecting the rebound in the bond markets, both of these funds reported gains
in portfolio value since February 28, 1995. The 12-month total returns on net
asset value for R Shares, reflecting portfolio gains plus reinvested dividend
income and capital gains distributions, if any, were 9.31% for the Municipal
Bond Fund and 10.94% for the Insured Municipal Bond Fund. These returns
translate to 12.59% and 14.10%, respectively, on a taxable-equivalent basis.
This strong performance rewarded investors who weathered the volatility of 1994,
and reminds us again of the importance of municipal bonds to a well-rounded,
long-term investment plan.

  As some of you may know, on June 30, 1996, I will be retiring as the Chairman
and Chief Executive Officer of John Nuveen & Co. Incorporated, and as Chairman
of the Board of the Nuveen Funds. As I look back over the 41 years I have spent
at Nuveen, I'm proud to have been associated with a firm that holds integrity,
honesty, and value as the cornerstones of its business. I'm confident that these
traditions will continue to be the hallmarks of Nuveen.

  Over the past few years, I have been working closely with other Nuveen
managers to ensure that the company and the funds continue to be guided by
strong and talented management following my retirement. Timothy Schwertfeger,
who has been with Nuveen since 1977, will succeed me as Chief Executive Officer
and Chairman of Nuveen. He currently serves as Executive Vice President of
Nuveen and President of the Nuveen Funds. I am very confident in his abilities
and the abilities of the entire Nuveen management team.

  The management transition has been well planned, and it will have no effect on
portfolio management or the way dividends are set. Our management team is
committed to continuing Nuveen's successful tradition of value investing and
prudent management, helping our shareholders meet their need for tax-free
investment income with a full range of investment choices.

  Our focus will continue to be on building shareholder value, providing
research-oriented management, and maintaining our leadership role in the
municipal bond market. With this focus, we anticipate many more years of
accomplishment for our shareholders and our firm.

 I'd like to take this occasion to thank you for selecting Nuveen mutual fund
investments.

Sincerely,

Answering your
questions



Tom Spalding, head of Nuveen's portfolio management team, discusses factors
affecting the municipal market and efforts made to provide value for
shareholders.

How did the investment climate over the past year affect municipal bonds?

  In 1995, the combination of slow economic growth and low inflation created the
ideal environment for the bond markets, which responded with a sustained rally.
Citing the lack of significant inflation, the Federal Reserve Board moved to cut
interest rates in July and December 1995, and again at the end of January 1996.
This succession of rate cuts helped to bring down long-term municipal bond
yields by almost 130 basis points over the year and to increase net asset
values. The rebound of the municipal bond market was not as great as that of the
taxable market due to the much-publicized discussion of major tax reform
legislation and concern about its potential impact on tax-free investments. Yet,
in 1995, most Nuveen mutual funds enjoyed taxable-equivalent total returns of
14% or better.

Tom Spalding, head of Nuveen's portfolio management team, answers investors'
questions on developments in the municipal market.

What was Nuveen's approach to investing during this period?

During 1995, we continued to pursue our philosophy of value investing, a
disciplined approach designed to deliver above-market performance by emphasizing
securities that offer good intrinsic value and that are underpriced or
undervalued by the market. This approach has been rewarded over the past year,
as we saw many of our portfolio holdings upgraded by the rating agencies,
confirming our Research Department's judgments about credit quality. We also
moved to protect current income by investing more of our portfolio in non-
callable bonds when possible. These bonds are less likely to be redeemed before
maturity so that their yield is assured for the long term in the event of
falling interest rates. As is our policy, we continue to invest only in
investment-grade quality securities.


Has Nuveen made any major investment changes over the past year?

No. In the search for income and total return, our value investing approach
continues to concentrate on individual bonds with current yields, prices, credit
quality, and future prospects that are exceptionally attractive relative to
other bonds in the market. Because attractive issues may appear any time over
the course of the year, we are constantly vigilant for new opportunities, with
the goal of ensuring that the funds are always positioned to meet their
objectives: as high a level of current tax-free income as is consistent with
preservation of capital. This means that our analysts continuously assess
investment

                                       6
<PAGE>
 
possibilities across the entire spectrum of geographical and sector
opportunities nationwide. Currently, we favor revenue bonds for essential
services, such as those issued by water and sewer facilities and utilities,
especially public power authorities providing electricity at competitive rates.
We have reduced our positions in general obligation bonds issued by counties and
cities, which have suffered financial strains as the result of spending cuts at
the state and federal levels.

What does Nuveen see as the impact of the flat tax proposals on the municipal
market?

Because of the implications for tax-free investments such as municipal bonds and
bond funds, we have been closely monitoring the various flat tax proposals
currently being debated in Congress. While the presidential primaries
spotlighted the debate, it is important to note that none of the proposals
currently under discussion has gained a strong consensus. In addition,
implementation of any measure that manages to pass both houses is at least two
years away. As the election year progresses, focus seems to be shifting from tax
reform to other economic matters. However, the high-profile discussion-and the
attendant concern about the potential impact of tax reform on tax-free
investments-did affect the market for municipal bonds in 1995, causing these
bonds to underperform their taxable counterparts for the year.



                                       7
<PAGE>
 
  Given the low likelihood that the tax preference on municipal bonds will be
eliminated or dramatically reduced in the near future, Nuveen believes that it
is inadvisable to manage our funds toward one specific outcome. Instead, we will
continue to follow our value investing philosophy as the optimal way to pursue
our investors' objectives. In our view, this approach offers investors greater
price stability in the event of volatile markets. Once the tax issue is
resolved, we're confident that municipal bonds-because of their high credit
quality and attractive yields-will continue to hold a strategic place in the
prudent investor's portfolio. We will continue to monitor developments in the
tax debate as well as changes in other economic and political conditions while
keeping our focus on achieving the objectives of your fund.


What is Nuveen's market outlook for 1996?

Although inflation currently remains low and economic growth remains moderate,
we continue to watch these factors for potential changes and impact on the bond
market. During this election year, we are also closely monitoring any changes in
economic and tax policy that may affect the municipal market. The fundamentals
in the long term are sound, with the supply of municipal bonds down from past
years, and with a growing number of individual investors seeking to diversify
their portfolios and to increase their tax-free income.

</TABLE>

The fund's current dividend of 4.15 cents per share for Class R Shares
translated into a distribution yield of 5.37% as of February 29, 1996. The
annual distribution yield is calculated by multiplying the dividend by 12, and
dividing this number by the current offering price. Investors in the 36% federal
income tax bracket would have to earn 8.39% on a taxable investment to match
this tax-free yield.

  During the fiscal year, your fund's net asset value (for Class R Shares)
increased by 3.11% from a year ago. The average annual total return on NAV for
this class was 9.31%, which translated into a taxable-equivalent total return of
12.59%.

  The fund's Class R Share SEC yield of 4.93% on February 29, 1996, translated
into 7.70% on a taxable-equivalent basis.


* One-year, 5-year and 10-year total return figures for Class R Shares are not

The fund's current dividend of 4.65 cents per share for Class R Shares
translated into a distribution yield of 5.11% as of February 29, 1996. The
annual distribution yield is calculated by multiplying the dividend by 12, and
dividing this number by the current offering price. Investors in the 36% federal
income tax bracket would have to earn 7.98% on a taxable investment to match
this tax-free yield.

  During the fiscal year, your fund's net asset value (for Class R Shares)
increased by 5.20% from a year ago. The average annual total return on NAV for
this class was 10.94%, which translated into a taxable-equivalent total return
of 14.10%.

  The fund's Class R Share SEC yield of 5.00% on February 29, 1996, translated
into 7.81% on a taxable-equivalent basis.

                                                               FEBRUARY 29, 1996


1. GENERAL INFORMATION AND SIGNIFICANT
ACCOUNTING POLICIES

At February 29, 1996, the nationally diversified Funds covered in this report
(the "Funds") are Nuveen Municipal Bond Fund and Nuveen Insured Tax-Free Bond
Fund, Inc. (comprising the Nuveen Insured Municipal Bond Fund). Each Fund
invests primarily in a diversified portfolio of municipal obligations issued by
state and local government authorities.

Municipal Bond was originally incorporated in Maryland on October 8, 1976 and
reorganized as a Massachusetts Business Trust at the close of business on June
12, 1995. Insured Municipal Bond was incorporated in Minnesota on July 11, 1986.

The Funds are registered under the Investment Company Act of 1940 as open-end,
diversified management investment companies.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
generally accepted accounting principles.

Securities valuation

Portfolio securities for which market quotations are readily available are
valued at the mean between the quoted bid and asked prices or the yield
equivalent. Portfolio securities for which market quotations are not readily
available are valued at fair value by consistent application of methods
determined in good faith by the Board of Directors/Trustees. Temporary
investments in securities that have variable rate and demand features qualifying
them as short-term securities are traded and valued at amortized cost.

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 be settled a month or more after the transaction date. Any securities so
purchased are subject to market fluctuation during this period. The Funds have
instructed the custodian to segregate assets in a separate account with a
current value at least equal to the amount of their purchase commitments. At
February 29, 1996, Insured Municipal Bond had purchase commitments of
$6,032,048. Municipal Bond had no such purchase commitments.

NOTES TO FINANCIAL STATEMENTS
 
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

Net investment income is declared as a dividend monthly and payment is made or
reinvestment is credited to shareholder accounts after month-end. Net realized
gains from securities transactions are distributed to shareholders not less
frequently than annually only to the extent they exceed available capital loss
carryovers. Distributions to shareholders of net investment income and net
realized gains from investment transactions are recorded on the ex-dividend
date. The amount and timing of such 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 result and will be classified as either distributions in
excess of net investment income or distributions in excess of net realized gains
from investment transactions, if applicable.

Federal income taxes

Each Fund is a separate taxpayer for federal income tax purposes and intends to
comply with the requirements of the Internal Revenue Code applicable to
regulated investment companies by distributing all of its net investment income,
in addition to any significant amounts of net realized gains from investments,
to shareholders. The Funds currently consider significant net realized gains as
amounts in excess of $.001 per share. Furthermore, each 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 Funds. All income dividends paid during
the year ended February 29, 1996, have been designated Exempt Interest
Dividends.

Insurance

Insured Municipal Bond invests in municipal securities which are either covered
by insurance or backed by an escrow or trust account containing sufficient U.S.
Government or U.S. Government agency securities, both of which ensure the timely
payment of principal and interest. Each insured municipal security is covered by
Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance.
Such insurance does not guarantee the market value of the municipal securities
or the value of the Fund's shares. Original Issued Insurance and Secondary
Market Insurance remain in effect as long as the municipal securities covered
thereby remain outstanding and the insurer remains in business, regardless of
whether the Fund ultimately disposes of such municipal securities. Consequently,
the market value of the municipal securities covered by Original Issue Insurance
or Secondary Market Insurance may reflect value attributable to the insurance.
Portfolio Insurance is effective only

                                      NUVEEN TAX-FREE MUTUAL FUNDS ANNUAL REPORT
                                                               FEBRUARY 29, 1996


while the municipal securities are held by the Fund. Accordingly, neither the
prices used in determining the market value of the underlying municipal
securities nor the net asset value of the Fund's shares include value, if any,
attributable to the Portfolio Insurance. Each policy of the Portfolio Insurance
does, however, give the Fund the right to obtain permanent insurance with
respect to the municipal security covered by the Portfolio Insurance policy at
the time of its sale.

Flexible sales charge program

Effective September 6, 1994, for Insured Municipal Bond and June 13, 1995, for
Municipal Bond, both Funds commenced offering Class "A" Shares and Class "C"
Shares. Class "A" Shares incur a front-end sales charge and an annual 12b-1
service fee. Class "C" Shares are sold without a sales charge but incur annual
12b-1 distribution and service fees. Effective June 13, 1995, for both Funds, an
investor purchasing Class "C" Shares agrees to pay a contingent deferred sales
charge ("CDSC") of 1% if Class "C" Shares are redeemed within 12 months of
purchase.

Prior to the offering of Class "A" Shares and Class "C" Shares, the shares
outstanding for both Funds were renamed Class "R" and are not subject to any
12b-1 distribution or service fees. Effective with the offering of the new
classes, Class "R" Shares are generally available only for reinvestment of
dividends by current "R" shareholders and for already established Nuveen Unit
Investment Trust reinvestment accounts.

Derivative financial instruments

In October 1994, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 119 Disclosure about Derivative
Financial Instruments and Fair Value of Financial Instruments which prescribes
disclosure requirements for transactions in certain derivative financial
instruments including future, forward, swap, and option contracts, and other
financial instruments with similar characteristics. Although the Funds are
authorized to invest in such financial instruments, and may do so in the future,
they did not make any such investments during the year ended February 29, 1996,
other than occasional purchases of high quality synthetic money market
securities, if applicable.

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.

2. EXPENSE ALLOCATION

Expenses of the Funds that are not directly attributable to any 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 are recorded to the specific
class. Effective August 1, 1995, the Funds adopted a multiple class plan
pursuant to Rule 18f-3 under the Investment Company Act of 1940 and now
designate class specific expenses to include Rule 12b-1 distribution and service
fees, and other expenses incurred for services received by a class that differ
in either amount or kind. A breakdown of the class specific expenses during the
year ended February 29, 1996, were as follows:

 For net assets over $2,000,000,000                    .425 of 1
- ----------------------------------------------------------------------
</TABLE>

The management fee is reduced by, or the Adviser assumes certain expenses of
each Fund, in an amount necessary to prevent the total expense of each Fund
(including the management fee, but excluding interest, taxes, fees incurred in
acquiring and disposing of portfolio securities, 12b-1 Service and Distribution
fees, if applicable, and to the extent permitted, extraordinary expenses) in any
fiscal year from exceeding .75 of 1% of the average daily net asset value of
Municipal Bond and .975 of 1% of the average daily net asset value of Insured
Municipal Bond. The Adviser may also voluntarily agree to reimburse additional
expenses from time to time, which may be voluntarily terminated at any time at
its discretion.

NOTES TO FINANCIAL STATEMENTS


The management fee compensates the Adviser for overall investment advisory and
administrative services, and general office facilities. The Funds pay no
compensation directly to their directors/trustees who are affiliated with the
Adviser or to its officers, all of whom receive remuneration for their services
to the Funds from the Adviser.

8. COMPOSITION OF NET ASSETS

At February 29, 1996, the Funds had common stock authorized of $.10 par value
per share for Municipal Bond and $.01 par value per share for Insured Municipal
Bond. The composition of net assets as well as the number of authorized shares

</TABLE>

Certain long-term and intermediate-term investments owned by the Funds 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 (30% for Municipal Bond and 100% for Insured Municipal
Bond). Such insurance or escrow, however, does not guarantee the market value of
the municipal securities or the value of the Funds' shares.

All of the temporary investments in short-term municipal securities have credit
enhancements (letters of credit, guarantees or insurance) issued by third party
domestic or foreign banks or other institutions.

For additional information regarding each investment security, refer to the
Portfolio of Investments of each Fund.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors, Trustees and Shareholders of
Nuveen Municipal Bond Fund
Nuveen Insured Tax-Free Bond Fund, Inc.:

We have audited the accompanying statements of net assets of NUVEEN MUNICIPAL
BOND FUND (a Massachusetts Business Trust), and NUVEEN INSURED TAX-FREE BOND
FUND, INC. (comprising the Nuveen Insured Municipal Bond Fund) (a Minnesota
corporation), including the portfolios of investments, as of February 29, 1996,
and the related statements of operations for the year then ended, the statements
of changes in net assets for each of the two years in the period then ended and
the financial highlights for the periods indicated thereon. 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
February 29, 1996, by correspondence with the 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, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of each of the
respective funds constituting Nuveen Municipal Bond Fund and Nuveen Insured Tax-
Free Bond Fund, Inc. as of February 29, 1996, the results of their operations
for the year then ended, the changes in their net assets for each of the two
years in the period then ended and the financial highlights for the periods
indicated thereon in conformity with generally accepted accounting principles.

ITEM 27: INDEMNIFICATION
Section 4 of Article XII of Registrant's Declaration of Trust provides as fol-
lows:
 
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 per-
mitted 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 negli-
  gence 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 adju-
  dicated not to have acted in good faith in the reasonable belief that his
  action was in the best interest 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 pay-
  ment by a Covered Person, unless there has been
 
                                                                             C-3
<PAGE>
 
  either a determination that such Covered Person did not engage in willful
  misfeasance, bad faith, gross negligence or reckless disregard of the du-
  ties involved in the conduct of his office by the court or other body ap-
  proving 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 poli-
cies 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 con-
tinue 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 oth-
erwise 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 ul-
  timately 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 anyone, as such Disinterested Trust-
ee, who has been exempted from being an Interested Person by any rule, regula-
tion 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, admin-
istrative or other, including appeals), actual or threatened; and the word "li-
ability" and "expenses" shall include without limitation, attorneys' fees,
costs, judgments, amounts paid in settlement, fines, penalties and other lia-
bilities.
 
                               -----------------
   
The trustees and officers of the Registrant are covered by an Investment Trust
Errors and Omissions policy in the aggregate amount of $60,000,000 (with a max-
imum deductible of $500,000) against     
 
C-4
<PAGE>
 
liability and expenses of claims of wrongful acts arising out of their posi-
tion with the Registrant (and such other companies), except for matters which
involve 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 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 other-
wise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as ex-
pressed 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 director or control-
ling person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such officer, director or controlling persons in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling pre-
cedent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by it is against public policy as expressed in the Act
and will be governed by the final adjudication of such issue.

                          NUVEEN MUNICIPAL BOND FUND

                   ESTABLISHMENT AND DESIGNATION OF CLASSES

    
    The undersigned, being a majority of the Trustees of Nuveen Municipal Bond
Fund, a Massachusetts business trust (the "Trust"), acting pursuant to Sections
1 and 2 of Article IV of the Declaration of Trust dated March 13, 1995, (the
"Declaration"), do hereby divide the Shares of its series, whether currently
existing or created in the future, into three Classes of Shares effective as of
the commencement of business on June 13, 1995, as follows:      

    1.  The three Classes of Shares are designated "Class A Shares", "Class C 
Shares" and "Class R Shares".

    2.  Class A Shares, Class C Shares and Class R Shares shall be entitled to 
all the rights and preferences accorded to Shares under the Declaration.

    3.  The number of Shares of each Class designated hereby shall be unlimited.

    4.  The purchase price of Class A Shares, Class C Shares and Class R Shares,
the method of determination of the net asset value of Class A Shares, Class C 
Shares and Class R Shares, the price, terms and manner of redemption of Class A 
Shares, Class C Shares and Class R Shares, any conversion or exchange feature or
privilege of the Class A Shares, Class C Shares and Class R Shares, and the 
relative dividend rights of the holders of Class A Shares, Class C Shares and 
Class R Shares shall be established by the Trustees of the Trust in accordance 
with the Declaration and shall be set forth in the current prospectus and 
statement of additional information of the Trust or any series thereof, as 
amended from time to time, contained in the Trust's registration statement under
the Securities Act of 1933, as amended (the "Prospectus").

    5.  Each of the Class A Shares, Class C Shares and Class R Shares shall bear
the expenses of payments under any distribution and service agreements entered 
into by or on behalf of the Trust with respect to that Class, and any other 
expenses that are properly allocated to such Class in accordance with the 
Investment Company Act of 1940, or any
<PAGE>
 
                                      -2-

rule or order issued thereunder and applicable to the Trust (the "1940 Act").

    6.  As to any matter on which shareholders are entitled to vote, Class A 
Shares, Class C Shares and Class R Shares of a series shall vote together as a 
single class; provided however, that notwithstanding the provisions of Section 4
of Article IX of the Declaration to the contrary, (a) as to any matter with 
respect to which a separate vote of any Class is required by the 1940 Act or is 
required by a separate agreement applicable to such Class, such requirements as 
to a separate vote by the Class shall apply, (b) except as required by (a) 
above, to the extent that a matter affects more than one Class and the interests
of two or more Classes in the matter are not materially different, then the 
Shares of such Classes whose interests in the matter are not materially 
different shall vote together as a single Class, but to the extent that a matter
affects more than one Class and the interests of a Class in the matter are 
materially different from that of each other Class, then the Shares of such 
Class shall vote as a separate class; and (c) except as required by (a) above or
as otherwise required by the 1940 Act, as to any matter which does not affect 
the interests of a particular Class, only the holders of Shares of the one or 
more affected Classes shall be entitled to vote.

    7.  The designation of Class A Shares, Class C Shares and Class R Shares 
hereby shall not impair the power of the Trustees from time to time to designate
additional classes of Shares of the Trust.

    8.  Subject to the applicable provisions of the 1940 Act, the Trustees may 
from time to time modify the preferences, voting powers, rights and privileges 
of any of the Classes designated hereby without any action or consent of the 
Shareholders.
    
        IN WITNESS WHEREOF, the undersigned has executed this certificate this
12th day of June, 1995.

                        INVESTMENT MANAGEMENT AGREEMENT
                        -------------------------------

    AGREEMENT made this 13th day of June, 1995, by and between NUVEEN MUNICIPAL 
BOND FUND, a Massachusetts business trust (the "Fund"), and NUVEEN ADVISORY 
CORP., a Delaware corporation (the "Adviser").

                              W I T N E S S E T H
                              -------------------

    In consideration of the mutual covenants hereinafter contained, it is hereby
agreed by and between the parties hereto as follows:

    1. The Fund hereby employs the Adviser to act as the investment adviser for,
and to manage the investment and reinvestment of the assets of the Fund in
accordance with the Fund's investment objective and policies and limitations,
and to administer its affairs to the extent requested by and subject to the
supervision of the Board of Trustees of the Fund for the period and upon the
terms herein set forth. The investment of such assets shall be subject to the
Fund's policies, restrictions and instructions with respect to securities
investments as set forth in the Fund's Registration Statement on Form N-1A under
the Securities Act of 1933 and the Investment Company Act of 1940 covering the
Fund's shares of beneficial interest, including the Prospectus forming a part
thereof, all as filed with the Securities and Exchange Commission and as from
time to time amended, and all applicable laws and the regulations of the
Securities and Exchange Commission relating to the management of registered 
open-end, diversified management investment companies.

<PAGE>
 
    The Adviser accepts such employment and agrees during such period to render 
such services, to furnish office facilities and equipment and clerical, 
bookkeeping and administrative services (other than such services, if any, 
provided by the Fund's transfer agent and shareholder service agent) for the 
Fund, to permit any of its officers or employees to serve without compensation 
as trustees or officers of the Fund if elected to such positions, and to assume 
the obligations herein set forth for the compensation herein provided. The 
Adviser shall, for all purposes herein provided, be deemed to be an independent 
contractor and, unless otherwise expressly provided or authorized, shall have no
authority to act for nor represent the Fund in any way, nor otherwise be deemed 
an agent of the Fund.

    2. For the services and facilities described in Section 1, the Fund will pay
to the Adviser, at the end of each calendar month, an investment management fee 
computed at an annual rate of:

           Rate          Net Assets
           ----          ----------
           .5000%        For the first $125 million
           .4875%        For the next $125 million
           .4750%        For the next $250 million
           .4625%        For the next $500 million
           .4500%        For the next $1 billion
           .4250%        On assets of $2 billion and over

For the month and year in which this Agreement becomes effective, or terminates,
there shall be an appropriate proration on the basis of the number of days that 
the Agreement shall have been in effect during the month and year, respectively.
The services of the Adviser to the Fund under

<PAGE>
 
this Agreement are not to be deemed exclusive, and the Adviser shall be free to 
render similar services or other services to others so long as its services 
hereunder are not impaired thereby.

    3. In addition to the services and facilities described in Section 1 the 
Adviser shall assume and pay to the extent hereafter provided: (x) any expenses 
for services rendered by a custodian for the safekeeping of the Fund's 
securities or other property, for keeping its books of account, for calculating 
the net asset value of the Fund as provided in the Declaration of Trust of the 
Fund, and any other charges of the custodian; and (y) the cost and expenses of 
the Fund's operations, including compensation of the trustees, transfer, 
dividend disbursing and shareholder service agent expenses, legal fees, expenses
of independent accountants, costs of share certificates, expenses of preparing, 
printing and distributing reports to shareholders and governmental agencies, and
all fees payable to Federal, State, or other governmental agencies on account of
the registration of securities issued by the Fund, filing of corporate documents
or otherwise. Notwithstanding the foregoing, the Adviser shall not be obligated 
to assume or pay interest, taxes, fees incurred in acquiring and disposing of 
portfolio securities or extraordinary expenses of the Fund. The Fund shall not 
incur any obligation for management or administrative expenses which the Fund 
intends the Adviser to assume and pay hereunder without first obtaining the 
written approval of the Adviser.

    The Adviser shall arrange for officers or employees of the Adviser to serve,
without compensation from the Fund, as trustees, officers or agents of the Fund,
if duly elected or appointed to such positions, and subject to their individual 
consent and to any limitations imposed by law.

<PAGE>
 
    The foregoing enumerated expenses are hereby assumed by the Adviser to the 
extent they, together with the Adviser's fee payable hereunder (but excluding 
interest, taxes, fees incurred in acquiring and disposing of portfolio 
securities and extraordinary expenses), exceed during any fiscal year .75 of 1% 
of the Fund's average net assets for such year; to the extent they do not exceed
such percentage, such expenses shall be properly chargeable to the Fund. If, at 
the end of any month, the expenses of the Fund properly chargeable to the income
account on a year-to-date basis shall exceed the appropriate percentage of 
average net assets, the payment to the Adviser for that month shall be reduced 
and, if necessary, the Adviser shall assume and pay expenses pursuant hereto so 
that the total year-to-date net expense will not exceed such percentage. As of 
the end of the Fund's fiscal year the foregoing computation and assumption of 
expenses shall be readjusted, if necessary, so that the expenses assumed and 
paid by the Adviser, if any, are such, and the aggregate compensation payable to
the Adviser for the year, (otherwise equal to the percentage set forth in
Section 2 hereof of the average net asset value as determined and described
herein throughout the fiscal year) is diminished as may be necessary, so that
the total amount of expenses borne by the Fund shall not exceed the applicable
expense limitation.

    The net asset value of the Fund shall be calculated as provided in the 
Declaration of Trust of the Fund. On each day when net asset value is not 
calculated, the net asset value of a share of beneficial interest of the Fund 
shall be deemed to be the net asset value of such share as of the close of 
business on the last day on which such calculation was made for the purpose of 
the foregoing computations.

<PAGE>
 
    4. Subject to applicable statutes and regulations, it is understood that 
officers, trustees, or agents of the Fund are, or may be, interested in the 
Adviser as officers, directors, agents, shareholders or otherwise, and that the 
officers, directors, shareholders and agents of the Adviser may be interested in
the Fund otherwise than as trustees, officers or agents.

    5. The Adviser shall not be liable for any loss sustained by reason of the 
purchase, sale or retention of any security, whether or not such purchase, sale 
or retention shall have been based upon the investigation and research made by 
any other individual, firm or corporation, if such recommendation shall have 
been selected with due care and in good faith, except loss resulting from 
willful misfeasance, bad faith, or gross negligence on the part of the Adviser 
in the performance of its obligations and duties, or by reason of its reckless 
disregard of its obligations and duties under this Agreement.

    6. The Adviser reserves the right to manage other investment accounts and 
funds, including those with investment objectives similar to the Fund. In the 
event that the Adviser manages other investment accounts or funds, securities 
considered as investments for the Fund may also be appropriate for such other 
investment accounts and funds that may be managed by the Adviser. Subject to 
applicable laws and regulations, the Adviser will attempt to allocate equitably 
portfolio transactions among the Fund and the portfolios of its other investment
accounts and funds purchasing securities whenever decisions are made to purchase
or sell securities by the Fund and one or more of such other accounts or funds
simultaneously. In making such allocations, the main factors to be considered by
the Adviser will be the respective


<PAGE>
 
investment objectives of the Fund and such other accounts and funds, the 
relative size of portfolio holdings of the same or comparable securities, the 
availability of cash for investment by the Fund and such other accounts and 
funds, the size of investment commitments generally held by the fund and such 
accounts and funds, and the opinions of the persons responsible for recommending
investments to the Fund and such other accounts and funds.

    7. This Agreement shall continue in effect until August 1, 1996, unless and 
until terminated by either party as hereinafter provided, and shall continue in 
force from year to year thereafter, but only as long as such continuance is 
specifically approved, at least annually, in the manner required by the 
Investment Company Act of 1940.

    This Agreement shall automatically terminate in the event of its assignment,
and may be terminated at any time without the payment of any penalty by the Fund
or by the Adviser upon sixty (60) days' written notice to the other party. The 
Fund may effect termination by action of the Board of Trustees, or by vote of a 
majority of the outstanding shares of beneficial interest of the Fund, 
accompanied by appropriate notice.

    This Agreement may be terminated, at any time, with the payment of any 
penalty, by the Board of Trustees of the Fund, or by vote of a majority of the 
outstanding shares of beneficial interest of the Fund, in the event that it 
shall have been established by a court of competent jurisdiction that the 
Adviser, or any officer or director of the Adviser, has taken any action which 
results in a breach of the covenants of the Adviser set forth herein.

<PAGE>
 
    Termination of this Agreement shall not affect the right of the Adviser to 
receive payments on any unpaid balance of the compensation, described in 
Section 2, earned prior to such termination.

    8. If any provision of this Agreement shall be held or made invalid by a 
court decision, statute, rule, or otherwise, the remainder shall not be thereby 
affected.

    9. The Adviser and its affiliates reserve the right to grant, at any time, 
the use of the name "Nuveen," or any approximation or abbreviation thereof, to 
any other investment company or business enterprise. Upon termination of this 
Agreement by either party, or by its terms, the Fund shall thereafter refrain 
from using any name of the Fund which includes "Nuveen," or any approximation or
abbreviation thereof, or is sufficiently similar to such name as to be likely to
cause confusion with such name, and shall not allude in any public statement or 
advertisement to the former association.

    10. Any notice under this Agreement shall be in writing, addressed and 
delivered or mailed, postage prepaid, to the other party at such address as such
other party may designate for receipt of such notice.

    11. The Declaration of Trust of the Fund on file with the Secretary of State
of the Commonwealth of Massachusetts was executed on behalf of the Fund by the 
initial trustee of the Fund and not individually, and any obligation of the Fund
shall be binding only upon the assets

<PAGE>
 
of the Fund (or applicable series thereof) and shall not be binding upon any 
trustee, officer or shareholder of the Fund. Neither the authorization of any 
action by the trustees or shareholders of the Fund nor the execution of this 
agreement on behalf of the Fund shall impose any liability upon any trustee, 
officer or shareholder of the Fund.

    IN WITNESS WHEREOF, the Fund and the Adviser have caused this Agreement to 
be executed on the day and year above written.

                            DISTRIBUTION AGREEMENT
                            ----------------------

    AGREEMENT made as of this 13th day of June 1995, between NUVEEN MUNICIPAL 
BOND FUND, a Massachusetts business trust (the "Fund"), and JOHN NUVEEN & CO. 
INCORPORATED, a Delaware corporation (the "Underwriter").

                              W I T N E S S E T H
                              -------------------

    In consideration of the mutual covenants hereinafter contained, it is hereby
agreed by and between the parties hereto as follows:

    1. The Fund hereby appoints the Underwriter its agent for the distribution
of shares of beneficial interest, par value $.10 per share, including such Class
or Classes of shares as may now or hereafter be authorized, (the "Shares") in
jurisdictions wherein Shares may legally be offered for sale; provided, however,
that the Fund, in its absolute discretion, may: (a) issue or sell Shares
directly to holders of Shares of the Fund upon such terms and conditions and for
such consideration, if any, as it may determine, whether in connection with the
distribution of subscription or purchase rights, the payment or reinvestment of
dividends or distributions, or otherwise; and (b) issue or sell Shares at net
asset value in connection with merger or consolidation with, or acquisition of
the assets of, other investment companies or similar companies.

    2. The Underwriter hereby accepts appointment as agent for the distribution 
of the Shares and agrees that it will use its best efforts to sell such part of 
the authorized Shares remaining unissued as from time to time shall be 
effectively registered under the Securities Act
<PAGE>
 
of 1933 ("Securities Act"), at prices determined as hereinafter provided and on 
terms hereinafter set forth, all subject to applicable Federal and State laws 
and regulations and to the Declaration of Trust of the Fund.

    3. The Fund agrees that it will use its best efforts to keep effectively 
registered under the Securities Act for sale, as herein contemplated, such
Shares as the Underwriter shall reasonably request and as the Securities and
Exchange Commission shall permit to be so registered.

    4. Notwithstanding any other provision hereof, the Fund may terminate, 
suspend, or withdraw the offering of the Shares, or Shares of any Class, 
whenever, in its sole discretion, it deems such action to be desirable.

    5. The Underwriter shall sell Shares to, or through, brokers, dealers or 
qualified financial intermediaries (hereinafter referred to as "dealers"), or 
others, in such manner not inconsistent with the provisions hereof and the then 
effective Registration Statement of the Fund under the Securities Act (and 
related Prospectus and Statement of Additional Information) as the Underwriter 
may determine from time to time, provided that no dealer, or other person, shall
be appointed nor authorized to act as agent of the Fund without the prior 
consent of the Fund.

The Underwriter shall have the right to enter into agreements with brokers, 
dealers and banks (referred to herein as "dealers") of its choice for the sale 
of Shares and fix therein the portion of the sales charge which may be allocated
to such dealers; provided that the Fund shall approve the form of such 
agreements and shall evidence such approval by filing said form and any

                                       2
<PAGE>
 
amendments thereto as exhibits to its currently effective registration statement
under the Securities Act. Shares sold to dealers shall be for resale by such 
dealers only at the public offering price(s) set forth in the Fund's then 
current prospectus. The current forms of such agreements are attached hereto as 
Exhibits 1, 2 and 3.

    6. Shares offered for sale, or sold by the Underwriter, shall be so offered 
or sold at a price per Share determined in accordance with the then current 
Prospectus relating to the sale of Shares except as departure from such prices 
shall be permitted by the rules and regulations of the Securities and Exchange 
Commission. Any public offering price shall be the net asset value per Share 
plus a sales charge of not more than 4.75% of such public offering price. Shares
may be sold at net asset value without a sales charge to such class or classes 
of investors or in such class or classes of transactions as may be permitted 
under applicable rules of the Securities and Exchange Commission and as
described in the then current Prospectus of the Fund. The net asset value per
Share of each Class shall be computed in accordance with the Declaration of 
Trust of the Fund and shall be determined in the manner, and at the time, set 
forth in the then current prospectus of the Fund relating to such Shares.

    7. The price the Fund shall receive for all Shares purchased from the Fund 
shall be the net asset value used in determining the public offering price 
applicable to the sale of such Shares. The excess, if any, of the sales price 
over the net asset value of Shares sold by the Underwriter as agent shall be 
retained by the Underwriter as a commission for its services hereunder. Out of 
such commission, the Underwriter may allow commissions or concessions to dealers
in such amounts as the Underwriter shall determine from time to time. Except as 
may be

                                       3
<PAGE>
 
otherwise determined by the Underwriter and the Fund from time to time, such 
commissions or concessions shall be uniform to all dealers.

    8. The Underwriter shall issue and deliver, or cause to be issued and 
delivered, on behalf of the Fund such confirmations of sales made by it as 
agent, pursuant to this Agreement, as may be required. At, or prior to, the time
of issuance of Shares, the Underwriter will pay, or cause to be paid, to the 
Fund the amount due the Fund for the sale of such Shares. Certificates shall be 
issued, or Shares registered on the transfer books of the Fund, in such names 
and denominations as the Underwriter may specify.

    9. The Fund will execute any and all documents, and furnish any and all 
information, which may be reasonably necessary in connection with the 
qualification of the Shares for sale (including the qualification of the Fund as
a dealer, where necessary or advisable) in such states as the Underwriter may
reasonably request (it being understood that the Fund shall not be required,
without it consent, to comply with any requirement which, in its opinion, is
unduly burdensome).

    10. The Fund will furnish to the Underwriter, from time to time, such 
information with respect to the Fund and the Shares as the Underwriter may 
reasonably request for use in connection with the sale of Shares. The 
Underwriter agrees that it will not use or distribute, nor will it authorize
dealers or others to use, distribute or disseminate, in connection with the sale
of such Shares, any statements other than those contained in the Fund's current
Prospectus and Statement of Additional Information, except such supplemental
literature or advertising as shall

                                       4
<PAGE>
 
be lawful under Federal and State securities laws and regulations, and that it 
will furnish the Fund with copies of all such material.

    11. The Underwriter shall order Shares from the Fund only to the extent that
it shall have received purchase orders therefor. The Underwriter will not make, 
nor authorize any dealers or others, to make: (a) any short sale of Shares; or 
(b) any sale of Shares to any officer or director of the Fund, nor to any 
officer or director of the Underwriter, or of any corporation or association 
furnishing investment advisory, managerial, or supervisory services to the Fund,
nor to any such corporation or association, unless such sales are made in 
accordance with the then current prospectus relating to the sale of such Shares.

    12. In selling Shares for the account of the Fund, the Underwriter will in 
all respects conform to the requirements of all State and Federal laws and the 
Rules of Fair Practice of the National Association of Securities Dealers, Inc. 
relating to such sales, and will indemnify and save harmless the Fund from any 
damage or expense on account of any wrongful act by the Underwriter or any 
employee, representative, or agent of the Underwriter. The Underwriter will 
observe and be bound by all the provisions of the Declaration of Trust of the 
Fund (and of any fundamental policies adopted by the Fund pursuant to the 
Investment Company Act of 1940, notice of which shall have been given by the 
Fund to the Underwriter) which at the time in any way require, limit, restrict, 
prohibit or otherwise regulate any action on the part of the Underwriter.

    13. The Underwriter will require each dealer to conform to the provisions 
hereof and of the Registration Statement (and related prospectus) at the time in
effect under the Securities

                                       5
<PAGE>
 
Act with respect to the public offering price of the Shares, and neither the 
Underwriter nor any such dealer shall withhold the placing of purchase orders so
as to make a profit thereby.

    14. The Fund will pay, or cause to be paid, expenses (including the fees and
disbursements of its own counsel) of any registration of Shares under the 
Securities Act, expenses of qualifying or continuing the qualification of the 
Shares for sale and, in connection therewith, of qualifying or continuing the 
qualification of the Fund as a dealer or broker under the laws of such states as
may be designated by the Underwriter under the conditions herein specified, and 
expenses incident to the issuance of the Shares such as the cost of Share 
certificates, issue taxes, and fees of the transfer and shareholder service 
agent. The Underwriter will pay, or cause to be paid, all expenses (other than 
expenses which any dealer may bear pursuant to any agreement with the 
Underwriter) incident to the sale and distribution of the Shares issued or sold 
hereunder, including, without limiting the generality of the foregoing, all: (a)
expenses of printing and distributing any Prospectus and Statement of Additional
Information and of preparing, printing and distributing or disseminating any
other literature, advertising and selling aids in connection with such offering
of the Shares for sale (except that such expenses need not include expenses
incurred by the Fund in connection with the preparation, printing and
distribution of any report or other communication to holders of Shares in their
capacity as such), and (b) expenses of advertising in connection with such
offering. No transfer taxes, if any, which may be payable in connection with the
issue or delivery of Shares sold as herein contemplated, or of the certificates
for such Shares, shall be borne by the Fund, and the Underwriter will indemnify
and hold harmless the Fund against liability for all such transfer taxes.

                                       6
<PAGE>
 
    15. This agreement shall continue in effect until May 1, 1990, unless and 
until terminated by either party as hereinafter provided, and will continue from
year to year thereafter, but only so long as such continuance is specifically 
approved, at least annually, in the manner required by the Investment Company 
Act of 1940. Either party hereto may terminate this agreement on any date by 
giving the other party at least six month's prior written notice of such 
termination, specifying the date fixed therefor.

Without prejudice to any other remedies of the Fund in any such event, the Fund 
may terminate this Agreement at any time immediately upon any failure of 
fulfillment of any of the obligations of the Underwriter hereunder.

    16. This agreement shall automatically terminate in the event of its 
assignment.

    17. Any notice under this agreement shall be in writing, addressed, and 
delivered or mailed, postage pre-paid, to other party at such address as such 
other party may designate for the receipt of such notice.

    18. The Declaration of Trust of the Fund on file with the Secretary of State
of the Commonwealth of Massachusetts was executed on behalf of the Fund by the 
initial trustee of the Fund and not individually, and any obligation of the Fund
shall be binding only upon the assets of the Fund (or applicable series thereof)
and shall not be binding upon any trustee, officer or shareholder of the Fund. 
Neither the authorization of any action by the trustees or shareholders of the 
Fund nor the execution of this agreement on behalf of the Fund shall impose any 
liability upon any trustee, officer or shareholder of the Fund.

                                       7

    IN WITNESS WHEREOF, the Fund and the Underwriters have caused this agreement
to be executed on its behalf as of the day and year first above written.

                    ---------------------------------------------
                    the Securities Act of 1933 (File No. 2-57408)
                    ---------------------------------------------

Ladies and Gentlemen:

     We have acted as counsel for Nuveen Municipal Bond Fund, a
Massachusetts business trust (the "Fund"), in connection with the Fund's
Post-Effective Amendment Number 33 to its Registration Statement on Form N-1A
as proposed to be filed with the Securities and Exchange Commission on June 28,
1996 (the "Amendment") pursuant to Rule 485(b) of the Securities Act of 1933
(the "1933 Act") (as proposed to be amended, the "Registration Statement") with
respect to certain of its Shares of Beneficial Interest, par value $.01 per
share, designated as (i) Class A Common Shares (the "Class A Shares"), (ii)
Class C Common Shares (the "Class C Shares") and (iii) Class R Common Shares
(the "Class R Shares") (such Class A Shares, Class C Shares and Class R Shares
referred to collectively herein as the "Shares"). This opinion is being
delivered to you in connection with the Fund's filing of such Amendment. With
your permission, all assumptions and statements of reliance herein have been
made without any independent investigation or verification on our part except to
the extent otherwise expressly stated, and we express no opinion with respect to
the subject matter or accuracy of such assumptions or items relied upon.

     In connection with this opinion, we have reviewed, among other things,
executed copies of the following documents:

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

     (b)   copies, certified by the Secretary of State of the Commonwealth of
           Massachusetts, of the Fund's Declaration of Trust and of all
           amendments thereto on file in the office of the Secretary of State;

     (c)   a certificate executed by Karen L. Healy, an Assistant Secretary of
           the Fund, certifying as to, and attaching copies of, the Fund's
           Declaration of Trust and By-Laws, as amended, and certain votes of
           the Trustees of the Fund; and

     (d)   a printer's proof, dated June 26, 1996, of the Amendment.

     In our capacity as counsel to the Fund, we have examined the originals, or
certified, conformed or reproduced copies, of all records, agreements, 
instruments and documents as we have deemed relevant or necessary as the basis
for the opinions hereinafter expressed.  In all such examinations, we have 
assumed the legal capacity of all natural persons executing documents, the 
genuineness of all signatures, the authenticity of all original or certified
copies, and the conformity to original or certified copies of all copies 
submitted to us as conformed or reproduced copies.  As to various questions of 
fact relevant to such opinions, we have relied upon, and assume the accuracy of,
certificates and oral or written statements of public officials and officers or
representatives of the Fund.  We have assumed that the Amendment, as filed with 
the Securities and Exchange Commission, will be in substantially the form of the
printer's proof referred to in paragraph (d) above.

     Based upon, and subject to, the limitations set forth herein, we are of the
opinion that the Shares, when issued and sold in accordance with the Fund's
Declaration of Trust and By-Laws, and for the consideration described in the 
Registration Statement, will be legally issued, fully paid and non-assessable,
except that, as set forth in the Registration Statement, shareholders of the 
Fund may, under certain circumstances, be held personally liable for its 
obligations.

     The opinion expressed herein is limited to the laws of the Commonwealth of
Massachusetts.

                          NUVEEN MUNICIPAL BOND FUND

                       PLAN OF DISTRIBUTION AND SERVICE
                            PURSUANT TO RULE 12b-1
    
                                                                   June 12, 1995
                                                                                
WHEREAS, Nuveen Municipal Bond Fund, a Massachusetts business trust (the "Fund")
engages in business as an open-end management investment company and is 
registered under the Investment Company Act of 1940, as amended (The "Act");
    
WHEREAS, the Fund employs John Nuveen & Co. Incorporated (the "Distributor") as 
distributor of the shares of common stock of the Fund (the "Shares") pursuant to
a Distribution Agreement dated as of June 12, 1995;     

WHEREAS, the Fund is authorized to issue Shares in three different classes 
("Classes"): Class A, Class C and Class R;

WHEREAS, the Fund desires to adopt a Plan of Distribution and Service pursuant 
to Rule 12b-1 under the Act ("Rule 12b-1"), and the Board of Trustees of the 
Fund has determined that there is a reasonable likelihood that adoption of this 
Plan of Distribution and Service will benefit the Fund and its shareholders;

WHEREAS, the Fund, along with several other investment companies for which the 
Distributor serves as distributor, has obtained an exemptive order (the "Order")
from the Securities and Exchange Commission (SEC) to enable the various Classes 
of Shares to be granted different rights and privileges and to bear different 
expenses, and has an effective registration statement on file with the SEC 
containing a Prospectus describing such Classes of Shares;

WHEREAS, as described in the Order, the purchase of Class A Shares is generally 
subject to an up-front sales charge, not to exceed 4.50% of the purchase price, 
and the purchase of Class C Shares will not be subject to an up-front sales 
charge, but in lieu thereof the Class C Shares will be subject to an asset-based
distribution fee, as described below; 

WHEREAS, Class C Shares redeemed within 12 months of purchase may be subject to 
a contingent deferred sales charge ("CDSC"); and

WHEREAS, Shares representing an investment in Class C will automatically 
convert to Class A Shares 72 months after investment, as described in the 
Prospectus for the Shares;

NOW, THEREFORE, the Fund hereby adopts, and the Distributor hereby agrees to the
terms of, this Plan of Distribution and Service (the "Plan") in accordance with 
Rule 12b-1, on the following terms and conditions:

1.  (a)  The Fund is authorized to compensate the Distributor for services 
performed and expenses incurred by the Distributor in connection with the 
distribution of shares of Class A and Class C of the Fund and the servicing of 
accounts holding such Shares.

<PAGE>
 
     (b) The amount of such compensation paid during any one year shall consist
with respect to Class A Shares of a Service Fee not to exceed .25% of average
daily net assets of the Class A Shares of the Fund; and consist with respect to
Class C Shares of a Service Fee not to exceed .25% of average daily net assets
of the Class C Shares of the Fund, plus a Distribution Fee (in lieu of an up-
front sales charge) not to exceed .75% of average daily net assets of the Class
C Shares of the Fund less the amount of any CDSC received by the Distributor and
for which any applicable reinstatement privilege has expired. Such compensation
shall be calculated and accrued daily and paid quarterly or at such other
intervals as the Board of Trustees may determine.

     (c)  The Distributor shall pay any Distribution Fees it receives under the 
Plan with respect to Class C Shares of the Fund for which a particular 
underwriter, dealer, broker, bank or other selling entity (including the 
Distributor) having a Dealer Distribution Agreement in effect ("Authorized 
Dealer") is the dealer of record to such Authorized Dealers to compensate such 
organizations in connection with sales of Shares of Class C of the Fund. The 
Distributor may retain any Distribution Fees not so paid. Payments of 
Distribution Fees to any Authorized Dealer as of any quarter-end will not exceed
 .75% per year based on average net assets of accounts for which such Authorized 
Dealer appeared on the records of the Fund and/or its transfer agent as the 
dealer of record during the preceding quarter.

     (d)  The Distributor shall pay any Service Fees it receives under the Plan 
with respect to a given Class A or C of the Fund for which a particular 
Authorized Dealer (including the Distributor) is the dealer of record to such 
Authorized Dealers to compensate such organizations for providing services to 
shareholders relating to their investment in such Class, including any or all of
the following activities: maintaining account records for shareholders who 
beneficially own Shares; answering inquiries relating to the shareholders' 
accounts, the policies of the Fund and the performance of their investment; 
providing assistance and handling transmission of funds in connection with 
purchase, redemption and exchange orders for Shares; providing assistance in 
connection with changing account setups and enrolling in various optional fund 
services; producing and disseminating shareholder communications or servicing 
materials; the ordinary or capital expenses, such as equipment, rent, fixtures, 
salaries, bonuses, reporting and recordkeeping and third party consultancy or 
similar expenses, relating to any activity for which payment is authorized by 
the Board; and the financing of any other activity for which payment is 
authorized by the Board. The Distributor may retain any Service Fees not so
paid. Payments of Service Fees to any organization as of any quarter-end will
not exceed .25% per year based on average net assets of accounts for which such
organization appeared on the records of the Fund and/or its transfer agent as
the organization of record during the preceding quarter.

2.  This Plan shall not take effect until the Plan, together with any related 
agreement(s), has been approved by votes of a majority of both (a) the Board of 
Trustees of the Fund, and (b) those Trustees of the Fund who are not "interested
persons" of the Fund (as defined in the Act) and who have no direct or indirect 
financial interest in the operation of the Plan or any agreements related to it 
(the "Rule 12b-1 Trustees") cast in person at a meeting (or meetings) called for
the purpose of voting on the Plan and such related Agreement(s).


                                       2
<PAGE>
 
3.  This Plan shall remain in effect until August 1, 1995, and shall continue in
effect thereafter so long as such continuance is specifically approved at least 
annually in the manner provided for approval of this Plan in paragraph 2.

4.  The Distributor shall provide to the Board of Trustees of the Fund and the 
Board shall review, at least quarterly, a written report of distribution- and 
service-related activities, Distribution Fees, Service Fees, and the purposes 
for which such activities were performed and expenses incurred.

5.  This Plan may be terminated at any time by vote of a majority of the Rule 
12b-1 Trustees or by vote of a majority (as defined in the Act) of the 
outstanding voting Shares of the Fund.

6.  This Plan may not be amended to increase materially the amount of 
compensation payable by the Fund with respect to Class A or Class C Shares under
paragraph 1 hereof unless such amendment is approved by a vote of at least a 
majority (as defined in the Act) of the outstanding voting Shares of that Class 
of Shares. No material amendment to the Plan shall be made unless approved in 
the manner provided in paragraph 2 hereof.

7.  While this Plan is in effect, the selection and nomination of the Trustees 
who are not interested persons (as defined in the Act) of the Fund shall be 
committed to the discretion of the Trustees who are not such interested persons.

8.  The Fund shall preserve copies of this Plan and any related agreements and 
all reports made pursuant to paragraph 4 hereof, for a period of not less than 
six years from the date of the Plan, any such agreement or any such report, as 
the case may be, the first two years in an easily accessible place.

    IN WITNESS WHEREOF, the Fund and Distributor have executed this Plan of 
Distribution and Servicing as of the day and year first above written.

                                                                      EXHIBIT 16
 
                 SCHEDULE OF COMPUTATION OF PERFORMANCE FIGURES
 
                                    I. YIELD
     
A. Yield Formula
 
  Yield is computed according to the following formula:
 
              A - B    /6/
  Yield = 2 [(----- +1)   - 1]    
                CD

  Where:
      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.
 
      D = the maximum offering price per share on the last day of the 
          period.
 
B. Yield Calculation
  
  The following is the 30-day yield as of February 29, 1996 for the Class A
  Shares: 
 
              [$166,099.53 - $24,546.29]     /6/
  Yield = 2 [(--------------------------  + 1) -1]
                [$3,939,268.81 X $9.72] 
                = 4.48% 
 
  The following is the 30-day yield as of February 29, 1996 for the Class C
  Shares: 
               [$8,572.00 - $2,425.94]        /6/
  Yield = 2 [(--------------------------  + 1) -1]
                [$202,456.31 X $9.26]   
                = 3.94%

  The following is the 30-day yield as of February 29, 1996 for the Class R
  Shares: 
 
             [$13,128,608.86 - $1,378,076.33]   /6/
  Yield = 2 [(------------------------------ + 1) -1]
                 [$311,265,443.52 X $9.28]      
                = 4.93%

- ----------
*The maximum sales charge in effect during the periods shown was 4.50%. 

Interest earned on tax-exempt obligations is determined as follows:     
 
  A. In the case of a tax-exempt obligation (1) with a current market premium
     or (2) issued at a discount where the current market discount is less
     than the then-remaining portions of the
 
                                                                               1
<PAGE>
 
    original issue discount, it is necessary to first compute the yield to
    maturity (YTM). The YTM is then divided by 360 and the quotient is multi-
    plied by the market value of the obligation (plus accrued interest).
 
  B. In the case of a tax-exempt obligation issued at a discount where the
     current market discount is in excess of the then-remaining portion of
     the original issue discount, the adjusted original issue discount basis
     of the obligation (plus accrued interest) is used in lieu of the market
     value of the obligation (plus accrued interest) in computing the yield
     to maturity (YTM). The YTM is then divided by 360 and the quotient is
     multiplied by the adjusted original issue basis of the obligation (plus
     accrued interest).
 
  C. In the case of a tax-exempt obligation issued without original issue
     discount and having a current market discount, the coupon rate of inter-
     est is used in lieu of the yield to maturity. The coupon rate is then
     divided by 360 and the quotient is multiplied by the par value of the
     obligation.
 
                          II. TAXABLE EQUIVALENT YIELD
 
A. Taxable Equivalent Yield Formula
 
  The Taxable Equivalent Yield Formula is as follows:
 
                                                  Tax Exempt Yield
                 Taxable Equivalent Yield = -----------------------------
                                            (1 - Federal income tax yield)
 
B. Taxable Equivalent Yield Calculation
   
  Based on a 1996 maximum federal income tax rate of 39.6%, the Taxable Equiva-
lent Yield for the Class A Shares, Class C Shares and Class R Shares for the
30-day period ended February 29, 1996 is as follows:

</TABLE>      

                             III. DISTRIBUTION RATE
 
A. Distribution Rate Formula
 
  The formula for calculation of distribution rate is as follows:
 
      Distribution Rate = 12 X most recent tax-exempt income dividend per
      share

A. Average Annual Total Return Formula
 
  Average Annual Total Return is computed according to the following formula:
 
                                T = ERV  /1//N    -1
                                   -----------
                                        P
  Where:      
      T = average annual total return.
                                       
      P = a hypothetical initial payment of $1,000.
 
      N = number of years.
 
      ERV = ending redeemable value of a hypothetical $1,000 payment made
           at the beginning of the 1, 5 or 10-year (or fractional portion
           thereof) periods at the end of such 1, 5 or 10-year (or frac-
           tional portion thereof) periods.

A. Cumulative Total Return Formula
 
  Cumulative Total Return is computed according to the following formula:
 
 
                                      ERV - P
                                  T = --------
                                         P
 
  Where:
      T =cumulative total return.
 
      P =a hypothetical initial payment of $1,000.
 
      ERV = ending redeemable value of a hypothetical $1,000 payment made
            at the inception of the Fund or at the first day of a speci-
            fied 1-year, 5-year or 10-year period.

                      VI. TAXABLE EQUIVALENT TOTAL RETURN
 
A. Taxable Equivalent Total Return Formula
 
  The Fund's taxable equivalent total return for a specific period is calcu-
lated by first taking a hypothetical initial investment in the Fund's shares on
the first day of the period, computing the Fund's total return for each calen-
dar year in the period according to the above formula, 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 of the Fund on an
after-tax basis, at a specified tax rate (usually the highest marginal federal
tax rate), calculated pursuant to the formula presented above under "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 re-
turn factor" for the calendar year. The taxable equivalent total return factors
for all the calendar years in the period 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 to-
tal return expressed as a percentage.

                     NUVEEN CALIFORNIA TAX-FREE FUND, INC.


                              Multiple Class Plan
                        Adopted Pursuant to Rule 18f-3


     WHEREAS, Nuveen Municipal Bond Fund, a Massachusetts business trust, Nuveen
Multistate Tax-Free Trust, a Massachusetts business trust, Nuveen Insured Tax-
Free Bond Fund, Inc., a Minnesota corporation, Nuveen Tax-Free Bond Fund, Inc.,
a Minnesota corporation, and Nuveen California Tax-Free Fund, Inc., a Maryland
corporation (each a "Fund" and collectively the "Funds"), each engage in
business as an open-end management investment company and are each registered as
such under the Investment Company Act of 1940, as amended (the "Act");

     WHEREAS, each Fund is authorized to and does issue shares of common stock
or shares of beneficial interest in separate series, with the shares
representing the interests in a separate portfolio of securities and other
assets (each Fund's series relating to long-term securities together with all
other such series subsequently established by a Fund being referred to herein
individually as a "Series" and collectively as the "Series");

     WHEREAS, each Fund is authorized to and has divided the shares of each
Series into three classes, designated as Class A Shares, Class C Shares and
Class R Shares; and

     WHEREAS, the Board of each Fund as a whole, and the Trustees or Directors,
as applicable, who are not interested persons of each such Fund (as defined in
the Act) (the "Non-Interested Members"), after having been furnished and having
evaluated information reasonably necessary to evaluate this Multiple Class Plan
(the "Plan"), have determined in the exercise of their reasonable business
judgment that the Plan is in the best interests of each class of each Series
individually, and each Series and the Fund as a whole.

     WHEREAS, each Fund adopted this Plan in accordance with Rule 18f-3 under
the Act, effective August 1, 1995.

     WHEREAS, each Fund's Board, as a whole, and the Non-Interested Members,
approved certain pricing enhancements that required amendments to this Plan.

     NOW, THEREFORE, each Fund hereby adopts this amended Plan, effective July
1, 1996, in accordance with Rule 18f-3 under the Act:

     1.  Class Differences.  Each class of shares of a Series shall represent 
interests in the same portfolio of investments of that Series and, except as 
otherwise set forth in this Plan, shall differ solely with respect to: (i) 
distribution, service and other charges and expenses as provided for in
<PAGE>
 
Sections 2 and 3 of this Plan; (ii) the exclusive right of each class of shares 
to vote on matters submitted to shareholders that relate solely to that class or
for which the interests of one class differ from the interests of another class 
or classes; (iii) such differences relating to eligible investors as may be set 
forth in the prospectus and statement of additional information of each Series, 
as the same may be amended or supplemented from time to time (each a 
"Prospectus" and "SAI" and collectively, the "Prospectus" and "SAI"); (iv) the 
designation of each class of shares; and (v) conversion features.

     2.  DISTRIBUTION AND SERVICE ARRANGEMENTS; CONVERSION FEATURES. Class A 
Shares, Class C Shares and Class R Shares of each Fund shall differ in the 
manner in which such shares are distributed and in the services provided to 
shareholders of each such class as follows:

          a) Class A Shares:

               (i)    Class A Shares shall be sold at net asset value subject to
                      a front-end sales charge set forth in the Prospectus and
                      SAI;

               (ii)   Class A Shares shall be subject to an annual service fee
                      ("Service Fee") pursuant to a Plan of Distribution and
                      Service Pursuant to Rule 12b-1 (the "12b-1 Plan") not to
                      exceed 0.25 of 1% of the average daily net assets of the
                      Series allocable to Class A Shares, which, as set forth in
                      the Prospectus, SAI and the 12b-1 Plan, may be used to
                      compensate certain authorized dealers for providing
                      ongoing account services to shareholders; and

               (iii)  Class A Shares shall not be subject to a Distribution Fee 
                      (as hereinafter defined); and

               (iv)   As described in the Prospectus and SAI, certain Class A 
                      shares redeemed within 18 months of purchase shall be
                      subject to a contingent deferred sales charge ("CDSC") of
                      1% of the lower of (a) the net asset value of Class A
                      Shares at the time of purchase or (b) the net asset value
                      of Class A Shares at the time of redemption, as set forth
                      in the Prospectus and SAI.

          b) Class C Shares:

               (i)    Class C Shares shall be sold at net asset value without a 
                      front-end sales charge;

               (ii)   Class C Shares shall be subject to a Service Fee pursuant 
                      to the 12b-1 Plan not to exceed 0.25 of 1% of average
                      daily net assets of the Series allocable to Class C
                      Shares, which, as set forth in the Prospectus, SAI and the
                      12b-1 Plan, may be used to compensate certain authorized
                      dealers for providing ongoing account services to
                      shareholders;

                                       2
<PAGE>
 
               (iii)  Class C Shares shall be subject to an annual distribution
                      fee ("Distribution Fee") pursuant to the 12b-1 Plan not to
                      exceed 0.75 of 1% of average daily net assets of the
                      Series allocable to Class C Shares less the amount of any
                      CDSC received by John Nuveen & Co. Incorporated, the
                      Funds' distributor, and for which any applicable
                      reinstatement period, as set forth in the Prospectus and
                      SAI, has expired, which, as set forth in the Prospectus,
                      SAI and the 12b-1 Plan, will be used to compensate certain
                      authorized dealers over time for the sale of Class C
                      Shares;

               (iv)   Class C Shares redeemed within 12 months of purchase shall
                      be subject to a CDSC of 1% of the lower of (a) the net
                      asset value of Class C Shares at the time of purchase or
                      (b) the net asset value of Class C Shares at the time of
                      redemption, as set forth in the Prospectus and SAI; and

               (v)    Class C Shares will automatically convert to Class A
                      Shares six years after purchase, as set forth in the
                      Prospectus and SAI.

          c) Class R Shares:

               (i)     Class R Shares shall be sold at net asset value without a
                       front-end sales charge;

               (ii)    Class R Shares shall not be subject to a Service Fee; and

               (iii)   Class R Shares shall not be subject to a Distribution
                       Fee.

          3.  ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES.  a) Investment
Income, and Realized and Unrealized Gains and Losses. The daily investment 
income, and realized and unrealized gains and losses, of a Series will be of 
allocated to each class of shares based on each class' relative percentage of 
the total value of shares outstanding of the Series at the beginning of the day,
after such net assets are adjusted for the prior day's capital share 
transactions.

              b) Series Level Expenses. Expenses that are attributable to a
Series, but not a particular class thereof ("Series level expenses"), will be
allocated to each class of shares based on each class' relative percentage of
the total value of shares outstanding of the Series at the beginning of the day,
after such net assets are adjusted for the prior day's capital share
transactions. Series level expenses include fees for services that are received
equally by the classes under the same fee arrangement. All expenses attributable
to a Series that are not "class level expenses" (as defined below) shall be
Series level expenses, including but not limited to transfer agency fees and
expenses, share registration expenses, and shareholder reporting expenses.

              c) Class Level Expenses. Expenses that are directly attributable
to a particular class of shares, including the expenses relating to the
distribution of a class' shares, or to services provided to the shareholders of
a class, as set forth in Section 2 of this Plan, will be incurred by that

                                       3

class of shares. Class level expenses include expenses for services that are
unique to a class of shares in either form or amount. "Class level expenses"
shall include, but not be limited to, 12b-1 Service Fees, 12b-1 Distribution
Fees, expenses associated with the addition of share classes to a fund (to the
extent that the expenses were not fully accrued prior to the issuance of the new
classes of shares), expenses of administrative personnel and services required
to support the shareholders of a specific class, litigation or other legal
expenses relating to a specific class of shares, directors' fees or expenses
incurred as a result of issues relating to a specific class of shares, and
accounting expenses relating to a specific class of shares.

          d) Fee Waivers and Expense Reimbursements. On a daily basis, if the 
Series level expenses and the class level expenses (not including 12b-1 plan 
payments) exceed the daily expense cap for the Series, an appropriate 
waiver/reimbursement will be made to the Series. The amount of such 
reimbursement to each class will be in an amount such that the expenses of the 
class with the highest expense ratio (excluding Service Fees and Distribution 
Fees) will be equal to the daily expense cap after reimbursement. The expense 
reimbursement will be allocated to each class of shares based on each class' 
relative percentage of the total value of shares outstanding of the Series at 
the beginning of the day, after such net assets are adjusted for the prior day's
capital share transactions.

     4.   Exchange Privilege. Shares of a class of a Series may be exchanged 
only for shares of the same class of another Series, except as otherwise set 
forth in the Prospectus and SAI.

     5.   Term and Termination. a) The Series. This Plan shall become effective 
with respect to each Series on August 1, 1995, and shall continue in effect with
respect to such Class A, Class C and Class R Shares of each such Series until 
terminated in accordance with the provisions of Section 5(c) hereof.

          b) Additional Series or Classes. This Plan shall become effective with
respect to any class of shares of a Series other than Class A, Class C or Class 
R and with respect to each additional Series or class thereof established by a 
Fund after the date hereof and made subject to this Plan upon commencement of 
the initial public offering thereof (provided that the Plan has previously been 
approved with respect to such additional Series or class by votes of a majority 
of both (i) the members of the Board of a Fund, as a whole, and (ii) the 
Non-Interested Members, cast at a meeting held before the initial public 
offering of such additional Series or classes thereof), and shall continue in 
effect with respect to each such additional Series or class until terminated in 
accordance with provisions of Section 5(c) hereof. An addendum setting forth
such specific and different terms of such additional series or classes shall be
attached to or made part of this Plan.

          c) Termination. This Plan may be terminated at any time with respect 
to any Fund or any Series or class thereof, as the case may be, by vote of a 
majority of both the members of the Board of a Fund, as a whole, and the 
Non-Interested Members. The Plan may remain in effect with respect to a 
particular Fund or any Series or class thereof even if it has been terminated in
accordance with this Section 5(c) with respect to any other Fund or Series or 
class thereof.

necessary to evaluate the Plan, have determined in the exercise of their
reasonable business judgment that the Plan is in the best interests of each

Future Fund and such Future Fund as a whole.

     7.   Amendments. a) General. Except as set forth below, any material
amendment to this Plan affecting a Fund or Series or class thereof shall require
the affirmative vote of a majority of both the members of the Board of that
Fund, as a whole, and the Non-Interested Members that the amendment is in the
best interests of each class of each Series individually and each Series as a
whole.

          b) Future Funds. Any amendment to the Plan solely for the purpose of 
adding a Future Fund as a party hereto in accordance with Section 6, will not 
require any action by the Boards of the Funds.
