                  NUVEEN FLAGSHIP KANSAS MUNICIPAL BOND FUND

FUND OVERVIEW

     INVESTMENT OBJECTIVE

     The investment objective of the fund is to provide you with as high a level
     of current interest income exempt from regular federal, state and, in some
     cases, local income taxes as is consistent with preservation of capital.

     HOW THE FUND PURSUES ITS OBJECTIVE
    
     The fund purchases only quality municipal bonds that are rated investment
     grade (AAA/Aaa to BBB/Baa) at the time of purchase by independent ratings
     agencies. The fund may buy non-rated municipal bonds if the fund's
     investment adviser judges them to be investment grade.

     The fund's investment adviser uses a value-oriented strategy and looks for
     higher-yielding and undervalued municipal bonds that offer the potential
     for above-average total return.     

     WHAT ARE THE RISKS OF INVESTING IN THE FUND?
    
     The principal risks of investing in the fund are interest rate and credit
     risk. Interest rate risk is the risk that interest rates will rise, causing
     bond prices to fall. Credit risk is the risk that an issuer of a municipal
     bond will be unable to make interest and principal payments. In general,
     lower rated bonds carry greater credit risk. The fund may bear additional
     risk because it invests primarily in Kansas bonds. The fund is
     non-diversified, and may invest more of its assets in a single issuer than
     a diversified fund. Greater concentration may increase risk. As with any
     mutual fund investment, loss of money is a risk of investing.    
    
     The fund seeks to limit risk by buying investment grade quality bonds in a
     variety of industry sectors.    

     IS THIS FUND RIGHT FOR YOU?

     The fund may be a suitable investment for you if you seek to:
     
       .  Earn regular monthly tax-free dividends;
       .  Preserve investment capital over time;
       .  Reduce taxes on investment income;
       .  Set aside money systematically for retirement, estate planning or
          college funding.

     You should not invest in this fund if you seek to:
       .  Pursue an aggressive, high-growth investment strategy;
       .  Invest through an IRA or 401(k) plan;
       .  Avoid fluctuations in share price.

     HOW THE FUND HAS PERFORMED
    
     The fund's investment adviser is Nuveen Advisory Corp., Nuveen's Premier
     Adviser(SM) for municipal bond investing. The chart and table below
     illustrate annual fund returns for each of the past five years as well as
     annualized fund, peer group and market benchmark returns for the one-, 
     five-year and inception periods ending December 31, 1997. This information
     is intended to help you assess the variability of fund returns over the
     past five years (and consequently, the potential rewards and risks of a
     fund investment).

     and other firms may charge additional fees for shareholder transactions or
     for advisory services. Please see their materials for details.

     of 5% during the first year, 4% during the second and third years, 3%
     during the fourth, 2% during the fifth and 1% during the sixth year.

     charge permitted under the National Association of Securities Dealers
     Conduct Rules.

                 NUVEEN FLAGSHIP KENTUCKY MUNICIPAL BOND FUND

     Fund Overview

     Investment Objective

     The investment objective of the fund is to provide you with as high a level
     of current interest income exempt from regular federal, state and, in some
     cases, local income taxes as is consistent with preservation of capital.

     How the Fund Pursues Its Objective

    
     The fund purchases only quality municipal bonds that are rated investment
     grade (AAA/Aaa to BBB/Baa) at the time of purchase by independent ratings
     agencies. The fund may buy non-rated municipal bonds if the fund's
     investment adviser judges them to be investment grade.

     The fund's investment adviser uses a value-oriented strategy and looks for
     higher-yielding and undervalued municipal bonds that offer the potential
     for above-average total return.     

     What are the Risks of Investing in the Fund?

    
     The principal risks of investing in the fund are interest rate and credit
     risk. Interest rate risk is the risk that interest rates will rise, causing
     bond prices to fall. Credit risk is the risk that an issuer of a municipal
     bond will be unable to make interest and principal payments. In general,
     lower rated bonds carry greater credit risk. The fund may bear additional
     risk because it invests primarily in Kentucky bonds. As with any mutual
     fund investment, loss of money is a risk of investing.     

    
     The fund seeks to limit risk by buying investment grade quality bonds in a
     variety of industry sectors.     

     Is This Fund Right For You?

     The fund may be a suitable investment for you if you seek to:

      . Earn regular monthly tax-free dividends;

      . Preserve investment capital over time;

      . Reduce taxes on investment income;
          
      . Set aside money systematically for retirement, estate planning or
        college funding.

     You should not invest in this fund if you seek to:

      . Pursue an aggressive, high-growth investment strategy;

      . Invest through an IRA or 401(k) plan;

      . Avoid fluctuations in share price.

     How The Fund Has Performed
    
     The fund's investment adviser is Nuveen Advisory Corp., Nuveen's Premier
     Adviser(SM) for municipal bond investing. The chart and table below
     illustrate annual fund returns for each of the past ten years as well as
     annualized fund, peer group and market benchmark returns for the one-, 
     five- and ten-year periods ending December 31, 1997. This information is
     intended to help you assess the variability of fund returns over the past
     ten years (and consequently, the potential rewards and risks of a fund
     investment).

     Fund Overview

     INVESTMENT OBJECTIVE

     The investment objective of the fund is to provide you with as high a level
     of current interest income exempt from regular federal, state and, in some
     cases, local income taxes as is consistent with preservation of capital.

     HOW THE FUND PURSUES ITS OBJECTIVE
    
     The fund purchases only quality municipal bonds that are rated investment
     grade (AAA/Aaa to BBB/Baa) at the time of purchase by independent ratings
     agencies. The fund may buy non-rated municipal bonds if the fund's
     investment adviser judges them to be investment grade.

     The fund's investment adviser uses a value-oriented strategy and looks for
     higher-yielding and undervalued municipal bonds that offer the potential
     for above-average total return.    

     WHAT ARE THE RISKS OF INVESTING IN THE FUND?

    
     The principal risks of investing in the fund are interest rate and credit
     risk. Interest rate risk is the risk that interest rates will rise, causing
     bond prices to fall. Credit risk is the risk that an issuer of a municipal
     bond will be unable to make interest and principal payments. In general,
     lower rated bonds carry greater credit risk. The fund may bear additional
     risk because it invests primarily in Kentucky bonds. The fund is
     non-diversified, and may invest more of its assets in a single issuer than
     a diversified fund. Greater concentration may increase risk. As with any
     mutual fund investment, loss of money is a risk of investing.    
    
     The fund seeks to limit risk by buying investment grade quality bonds in a
     variety of industry sectors.     

     IS THIS FUND RIGHT FOR YOU?

     The fund may be a suitable investment for you if you seek to:

          . Earn regular monthly tax-free dividends;

          . Preserve investment capital over time;

          . Reduce taxes on investment income;
          
          . Set aside money systematically for retirement, estate planning or
            college funding.

     You should not invest in this fund if you seek to:

          . Pursue an aggressive, high-growth investment strategy;

          . Invest through an IRA or 401(k) plan;

          . Avoid fluctuations in share price.

     HOW THE FUND HAS PERFORMED

    
     The fund's investment adviser is Nuveen Advisory Corp., Nuveen's Premier
     Adviser(SM) for municipal bond investing. The chart and table below
     illustrate annual fund returns for each of the past two years as well as
     annualized fund, peer group and market benchmark returns for the one-year
     and inception periods ending December 31, 1997. This information is
     intended to help you assess the variability of fund returns over the past
     two years (and consequently, the potential rewards and risks of a fund
     investment).

     ending 12/31/95 and 3/31/96. The bar chart and highest/lowest quarterly
     returns do not reflect sales charges, which would reduce returns, while the
     average annual return table does.

1.   Class A total returns reflect actual performance for all periods; Class C
     and R total returns reflect actual performance for periods since class
     inception, and Class A performance for periods prior to class inception,
     adjusted for the differences in fees between the classes (see "What are the
     Costs of Investing?"). The year-to-date return as of 6/30/98 was 
     1.78%.     
    
2.   Market Benchmark returns reflect the performance of the Lehman Brothers 5
     Year Municipal Bond Index, an unmanaged index comprised of a broad range of
     investment-grade municipal bonds.     

    
3.   Peer Group returns represent the average annualized returns of the funds in
     the Lipper Other States Short-Intermediate Municipal Debt Category. Returns
     assume reinvestment of dividends and do not reflect any applicable sales
     charges.     

4.   As a percent of offering price unless otherwise noted. Authorized Dealers
     and other firms may charge additional fees for shareholder transactions or
     for advisory services. Please see their materials for details.

5.   Class R shares may be purchased only under limited circumstances, or by
     specified classes of investors. See "How You Can Buy and Sell Shares."

6.   Reduced sales charges apply to purchases of $50,000 or more.  See "How You
     Can Buy and Sell Shares."

7.   As a percentage of lesser of purchase price or redemption proceeds.

8.   Certain Class A purchases at net asset value of $1 million or more may be
     subject to a contingent deferred sales charge (CDSC) if redeemed within 18
     months of purchase. See "How You Can Buy and Sell Shares."

9.   Class C shares redeemed within one year of purchase are subject to a 1%
     CDSC.

10.  Long-term holders of Class C shares may pay more in Rule 12b-1 fees and
     CDSCs than the economic equivalent of the maximum front-end sales charge
     permitted under the National Association of Securities Dealers Conduct
     Rules.

                 NUVEEN FLAGSHIP MICHIGAN MUNICIPAL BOND FUND
                                                        
     Fund Overview                                      
    
     Investment Objective                               
                                                        
     The investment objective of the fund is to provide you with as high a level
     of current interest income exempt from regular federal, state and, in some
     cases, local income taxes as is consistent with preservation of capital.

     How the Fund Pursues Its Objective  
                                         
    
     The fund purchases only quality municipal bonds that are rated investment
     grade (AAA/Aaa to BBB/Baa) at the time of purchase by independent ratings
     agencies. The fund may buy non-rated municipal bonds if the fund's
     investment adviser judges them to be investment grade.

     The fund's investment adviser uses a value-oriented strategy and looks for
     higher-yielding and undervalued municipal bonds that offer the potential
     for above-average total return.     

     What are the Risks of Investing in the Fund? 
 
    
     The principal risks of investing in the fund are interest rate and credit
     risk. Interest rate risk is the risk that interest rates will rise, causing
     bond prices to fall. Credit risk is the risk that an issuer of a municipal
     bond will be unable to make interest and principal payments. In general,
     lower rated bonds carry greater credit risk. The fund may bear additional
     risk because it invests primarily in Michigan bonds. As with any mutual
     fund investment, loss of money is a risk of investing.     

    
     The fund seeks to limit risk by buying investment grade quality bonds in a
     variety of industry sectors.     

     Is This Fund Right For You?

     The fund may be a suitable investment for you if you seek to:

      .   Earn regular monthly tax-free dividends;       

      .   Preserve investment capital over time;

      .   Reduce taxes on investment income;   
          
      .   Set aside money systematically for retirement, estate planning or
          college funding.

     You should not invest in this fund if you seek to:

      .   Pursue an aggressive, high-growth investment strategy;

      .   Invest through an IRA or 401(k) plan;                 

      .   Avoid fluctuations in share price.                    

     How the Fund Has Performed 
                                                                      
     The fund's investment adviser is Nuveen Advisory Corp., Nuveen's Premier
     Adviser(SM) for municipal bond investing. The chart and table below
     illustrate annual fund returns for each of the past ten years as well as
     annualized fund, peer group and market benchmark returns for the one-, 
     five- and ten-year periods ending December 31, 1997. This information is
     intended to help you assess the variability of fund returns over the past
     ten years (and consequently, the potential rewards and risks of a fund
     investment).

     Fund Overview                                 

     Investment Objective                          
                                                   
     The investment objective of the fund is to provide you with as high a level
     of current interest income exempt from regular federal, state and, in some
     cases, local income taxes as is consistent with preservation of capital.

     How the Fund Pursues Its Objective
                                       
    
     The fund purchases only quality municipal bonds that are rated investment
     grade (AAA/Aaa to BBB/Baa) at the time of purchase by independent ratings
     agencies. The fund may buy non-rated municipal bonds if the fund's
     investment adviser judges them to be investment grade.

     The fund's investment adviser uses a value-oriented strategy and looks for
     higher-yielding and undervalued municipal bonds that offer the potential
     for above-average total return.     

     What are the Risks of Investing in the Fund?
                                                     
     The principal risks of investing in the fund are interest rate and credit
     risk. Interest rate risk is the risk that interest rates will rise, causing
     bond prices to fall. Credit risk is the risk that an issuer of a municipal
     bond will be unable to make interest and principal payments. In general,
     lower rated bonds carry greater credit risk. The fund may bear additional
     risk because it invests primarily in Missouri bonds. The fund is
     non-diversified, and may invest more of its assets in a single issuer than
     a diversified fund. Greater concentration may increase risk. As with any
     mutual fund investment, loss of money is a risk of investing.    
    
     The fund seeks to limit risk by buying investment grade quality bonds in a
     variety of industry sectors.     

     Is This Fund Right For You?

     The fund may be a suitable investment for you if you seek to:

       .    Earn regular monthly tax-free dividends;  

       .    Preserve investment capital over time;    

       .    Reduce taxes on investment income;        

       .    Set aside money systematically for retirement, estate planning or
            college funding.

     You should not invest in this fund if you seek to:  

       .    Pursue an aggressive, high-growth investment strategy;  

       .    Invest through an IRA or 401(k) plan;                   

       .    Avoid fluctuations in share price.                      
                                                                    
     How the Fund Has Performed

     What are the Risks of Investing in the Fund?

                                                 
     The principal risks of investing in the fund are interest rate and credit
     risk. Interest rate risk is the risk that interest rates will rise, causing
     bond prices to fall. Credit risk is the risk that an issuer of a municipal
     bond will be unable to make interest and principal payments. In general,
     lower rated bond carry greater credit risk. The fund may bear additional
     risk because it invests primarily in Ohio bonds. As with any mutual fund
     investment, loss of money is a risk of investing.

The following example is intended to help you compare the cost of investing in
the fund with the cost of investing in other mutual funds. It assumes you invest
$10,000 in the fund for the time period indicated and then either redeem or do
not redeem your shares at the end of a period. The example assumes that your
investment has a 5% return each year and that the fund's operating expenses
remain the same. Your actual returns and costs may be higher or lower.

   INVESTMENT OBJECTIVE                                                      

   The investment objective of the fund is to provide you with as high a level
   of current interest income exempt from regular federal income taxes as is
   consistent with preservation of capital.

   HOW THE FUND PURSUES ITS OBJECTIVE                                        
    
   The fund purchases only quality municipal bonds that are rated investment
   grade (AAA/Aaa to BBB/Baa) at the time of purchase by independent ratings
   agencies. The fund may buy non-rated municipal bonds if the fund's investment
   adviser judges them to be investment grade.

   The fund's investment adviser uses a value-oriented strategy and looks for
   higher-yielding and undervalued municipal bonds that offer the potential for
   above-average total return.     

   WHAT ARE THE RISKS OF INVESTING IN THE FUND?      
                                                     
   The principal risks of investing in the fund are interest rate and credit
   risk. Interest rate risk is the risk that interest rates will rise, causing
   bond prices to fall. Credit risk is the risk that an issuer of a municipal
   bond will be unable to make interest and principal payments. In general,
   lower rated bonds carry greater credit risk. The fund may bear additional
   risk because it invests primarily in Wisconsin bonds. The fund is
   non-diversified, and may invest more of its assets in a single issuer than a
   diversified fund. Greater concentration may increase risk. As with any mutual
   fund investment, loss of money is a risk of investing.       
           
   The fund seeks to limit risk by buying investment grade quality bonds in a
   variety of industry sectors.                                             

   IS THIS FUND RIGHT FOR YOU?

      .    Earn regular monthly tax-free dividends;               
      .    Preserve investment capital over time;

      .    Pursue an aggressive, high-growth investment strategy;

The following example is intended to help you compare the cost of investing in
the fund with the cost of investing in other mutual funds.  It assumes you
invest $10,000 in the fund for the time period indicated and then either redeem
or do not redeem your shares at the end of a period. The example assumes that
your investment has a 5% return each year and that the fund's operating expenses
remain the same.  Your actual returns and costs may be higher or lower.

               What Securities We Invest In

               Each fund's investment objective may not be changed without
               shareholder approval. The following investment policies may be
               changed by the Board of Trustees without shareholder approval
               unless otherwise noted in this prospectus or the Statement of
               Additional Information.

               Municipal Obligations

               The funds invest primarily in municipal bonds that pay interest
               that is exempt from regular federal, state and, in some cases,
               local income tax. Income from these bonds may be subject to the
               federal alternative minimum tax.

                                           Section 2 How We Manage Your Money 17
<PAGE>
 
               States, local governments and municipalities issue municipal
               bonds to raise money for various public purposes such as building
               public facilities, refinancing outstanding obligations and
               financing general operating expenses.     

               The funds may purchase municipal bonds that represent lease
               obligations. These carry special risks because the issuer of the
               bonds may not be obligated to appropriate money annually to make
               payments under the lease. In order to reduce this risk, the funds
               will only purchase these bonds where the issuer has a strong
               incentive to continue making appropriations until maturity.
    
               Quality Municipal Bonds 

               The funds purchase only quality municipal bonds that are either
               rated investment grade (AAA/Aaa to BBB/Baa) by independent rating
               agencies at the time of purchase or are non-rated but judged to
               be investment grade by the funds' investment adviser. Each fund
               will invest at least 80% of its net assets in investment-grade
               quality municipal bonds. If suitable municipal bonds from a
               specific state are not available at attractive prices and yields,
               a fund may invest in municipal bonds of U.S. territories (such as
               Puerto Rico and Guam) which are exempt from regular federal,
               state, and local income taxes. The Michigan and Ohio Funds may
               not invest more than 20% of their net assets in these territorial
               municipal bonds.     

               Portfolio Maturity 
    
               Each fund buys municipal bonds with different maturities in
               pursuit of its investment objective, but maintains under normal
               market conditions an investment portfolio with an overall
               weighted average maturity within a defined range. The Kentucky
               Limited Term Fund maintains a weighted average portfolio maturity
               of 1 to 7 years. All of the other funds described in this
               prospectus are long-term funds and normally maintain a weighted
               average portfolio maturity of 15 to 30 years.     
    
               Short-term Investments

               Under normal market conditions, each fund may invest up to 20% of
               net assets in short-term, high quality municipal bonds. See "How
               We Manage Risk -- Hedging and Other Defensive Investment
               Strategies." The funds may invest in short-term, high quality
               taxable securities if suitable short-term municipal bonds are not
               available at reasonable prices and yields. For more information
               on eligible short-term investments, see the Statement of
               Additional Information.     

               Delayed Delivery Transactions 

               The funds may buy or sell securities on a when-issued or delayed-
               delivery basis, paying for or taking delivery of the securities
               at a later date, normally within 15 to 45 days of the trade. Such
               transactions involve an element of risk because the value of the
               security to be purchased may decline before the settlement date.

               How We Select Investments

               Nuveen Advisory selects municipal obligations for the funds based
               upon its assessment of a bond's relative value in terms of
               current yield, price, credit quality and future prospects. Nuveen
               Advisory is supported by

18 Section 2 How We Manage Your Money
<PAGE>
 
               Nuveen's award-winning team of specialized research analysts who
               review municipal securities available for purchase, monitor the
               continued creditworthiness of each fund's municipal investments,
               and analyze economic, political and demographic trends affecting
               the municipal markets. We utilize these resources to identify
               municipal obligations with favorable characteristics we believe
               are not yet recognized by the market. We then select those 
               higher-yielding and undervalued municipal obligations that we
               believe represent the most attractive values. 

               Portfolio Turnover

               A fund buys and sells portfolio securities in the normal course
               of its investment activities. The proportion of the fund's
               investment portfolio that is sold and replaced with new
               securities during a year is known as the fund's portfolio
               turnover rate. The funds intend to keep portfolio turnover
               relatively low in order to reduce trading costs and the
               realization of taxable capital gains. Each fund, however, may
               make limited short-term trades to take advantage of market
               opportunities or reduce market risk. 

               What the Risks Are

               Risk is inherent in all investing. Investing in a mutual fund --
               even the most conservative -- involves risk, including the risk
               that you may receive little or no return on your investment or
               even that you may lose part or all of your investment. Therefore,
               before investing you should consider carefully the following
               risks that you assume when you invest in these funds. Because of
               these and other risks, you should consider an investment in any
               of these funds to be a long-term investment.
    
               Interest rate risk: the risk that the value of the fund's
               portfolio will decline because of rising market interest rates
               (bond prices move in the opposite direction of interest rates).
               The longer the average maturity (duration) of a fund's portfolio,
               the greater its interest rate risk. See "What Securities We
               Invest In--Portfolio Maturity."


               Income risk: the risk that the income from the fund's portfolio
               will decline because of falling market interest rates. This can
               result when the fund invests the proceeds from new share sales,
               or from matured or called bonds, at market interest rates that
               are below the portfolio's current earnings rate.     

               Credit risk: the risk that an issuer of a bond is unable to meet
               its obligation to make interest and principal payments due to
               changing market conditions. Generally, lower rated bonds provide
               higher current income but are considered to carry greater credit
               risk than higher rated bonds. Year 2000 issues may affect the
               ability of municipal issuers to meet their payment obligations to
               their bond holders, and may adversely affect their credit
               ratings.

               State Concentration risk: because the funds primarily purchase
               municipal bonds from a specific state, each fund also bears
               investment risk from the economic, political or regulatory
               changes that could adversely affect municipal bond issuers in
               that state and therefore the value of the funds' investment
               portfolio. See "Appendix--Additional State Information." These
               risks may be greater for the Kansas, Kentucky Limited, Missouri
               and

               Wisconsin Funds, which as "non-diversified" funds may concentrate
               their investment in municipal bonds of certain issuers to a
               greater extent than the Kentucky, Michigan and Ohio Funds
               described in this prospectus, which are diversified funds.

               Inflation risk: the risk that the value of assets or income from
               investments will be less in the future as inflation decreases the
               value of money. As inflation increases, the value of the funds'
               assets can decline as can the value of the funds' distributions.
     
               How We Manage Risk

               In pursuit of its investment objective, each fund assumes
               investment risk, chiefly in the form of interest rate and credit
               risk. The funds limit this investment risk generally by
               restricting the type and maturities of municipal bonds they
               purchase, and by diversifying their investment portfolios
               geographically as well as across different industry sectors.

               Investment Limitations 

               The funds have adopted certain investment limitations (based on
               total assets) that cannot be changed without shareholder approval
               and are designed to limit your investment risk and maintain
               portfolio diversification. Each fund may not have more than: 

                . 25% in any one industry such as electric utilities or health
               care.

                .  10% in borrowings (33% if used to meet redemptions).
    
               As diversified funds, the Kentucky, Michigan and Ohio Funds may
               not have more than:

                .  5% in securities in any one issuer (except for U.S.
               Government securities or for 25% of the fund's total 
               assets).

               Hedging and Other Defensive Investment Strategies     

               Each fund may invest up to 100% in cash equivalents and short-
               term investments as a temporary defensive measure in response to
               adverse market conditions, or to keep cash on hand fully
               invested. During these periods, the weighted average maturity of
               a fund's investment portfolio may fall below the defined range
               described under "Portfolio Maturity."

               Each fund may also use various investment strategies designed to
               limit the risk of bond price fluctuations and to preserve
               capital. These hedging strategies include using financial futures
               contracts, options on financial futures, or options based on
               either an index of long-term tax-free securities or on debt
               securities whose prices, in the opinion of the funds' investment
               adviser, correlate with the prices of the funds' investments. The
               funds, however, have no present intent to use these strategies.

Section 3  How You Can Buy and Sell Shares

               You can choose from four classes of fund shares, each with a
               different combination of sales charges, fees, eligibility
               requirements and other features. Your financial adviser can help
               you determine which class is best for you. We offer a number of
               features for your convenience. Please see the Statement of
               Additional Information for further details.

               How to Choose a Share Class

               In deciding whether to purchase Class A, Class B, Class C or
               Class R shares, you should consider: 

               . the amount of your purchase; 

               . any current holdings of fund shares; 

               . how long you expect to hold the shares; 

               . the amount of any up-front sales charge; 

               . whether a contingent deferred sales charge (CDSC) would
                 apply upon redemption; 

               . the amount of any distribution or service fees that you may
                 incur while you own the shares;

               . whether you will be reinvesting income or capital gain
                 distributions in additional shares;

               . whether you qualify for a sales charge waiver or reduction.

    
               For a summary of the charges and expenses for each class, please
               see "What are the Costs of Investing?"     

               Class A Shares

               You can buy Class A shares at the offering price, which is the
               net asset value per share plus an up-front sales charge. You may
               qualify for a reduced sales charge, or the sales charge may be
               waived, as described in "How to Reduce Your Sales Charge." Class
               A shares are also subject to an annual service fee of .20% which
               compensates your financial adviser for providing ongoing service
               to you. The up-front Class A sales charge for all funds described
               in the prospectus except the Kentucky Limited Term Fund is as
               follows:

               (1) You can buy $1 million or more of Class A shares at net asset
               value without an up-front sales charge. Nuveen pays authorized
               dealers of record on these share purchases a sales commission of
               1.00% (0.50% for the Kentucky Limited Term fund) of the first
               $2.5 million, plus .50% of the next $2.5 million, plus .25% of
               the amount over $5.0 million. If you redeem your shares within 18
               months of purchase, you may have to pay a CDSC of 1% (0.50% for
               the Kentucky Limited Term fund) of either your purchase price or
               your redemption proceeds, whichever is lower. You do not have to
               pay this CDSC if your financial adviser has made arrangements
               with Nuveen and agrees to waive the commission.     

               Class B Shares

               You can buy Class B shares at the offering price, which is the
               net asset value per share without any up-front sales charge so
               that the full amount of your purchase is invested in the fund.
               However, you will pay annual distribution and service fees of
               .95% of average daily assets. The annual .20% service fee
               compensates your financial adviser for providing ongoing service
               to you. The annual .75% distribution fee compensates Nuveen for
               paying your financial adviser a 4% up-front sales commission,
               which includes an advance of the first year's service fee. If you
               sell your shares within six years of purchase, you will have to
               pay a CDSC based on either your purchase price or what you sell
               your shares for, whichever amount is lower, according to the
               following schedule. You do not pay a CDSC on any Class B shares
               you purchase by reinvesting dividends. The Kentucky Limited Term
               Fund does not currently offer B shares.

               Class B shares automatically convert to Class A shares eight
               years after you buy them so that the distribution fees you pay
               over the life of your investment are limited. You will continue
               to pay an annual service fee on any converted Class B shares.

               Class C Shares

               You can buy Class C shares at the offering price, which is the
               net asset value per share without any up-front sales charge so
               that the full amount of your purchase is invested in the fund.
               However, you will pay annual distribution and service fees of 1%.
               The annual .20% service fee compensates your financial adviser
               for providing ongoing service to you. The annual .55% (0.35% for
               the Kentucky Limited Term Fund) distribution fee reimburses
               Nuveen for paying your financial adviser an ongoing sales
               commission. Nuveen advances the first year's service and
               distribution fees. If you sell your shares within 12 months of
               purchase, you may have to     

22  Section 3   How You Can Buy and Sell Shares
<PAGE>
 
               pay a 1% CDSC based on either your purchase price or what you
               sell your shares for, whichever amount is lower. 

               Class R Shares

    
               Under limited circumstances, you may purchase Class R Shares at
               the offering price, which is the net asset value on the day of
               purchase. In order to qualify, you must be eligible under one of
               the programs described in "How to Reduce Your Sales Charge"
               (below) or meet certain other purchase size criteria. Class R
               Shares are not subject to sales charges or ongoing service or
               distribution fees. Class R shares have lower ongoing expenses
               than the other classes.     

               How to Reduce Your Sales Charge

               We offer a number of ways to reduce or eliminate the up-front
               sales charge on Class A shares or to qualify to purchase Class R
               shares.

               for detailed program descriptions and eligibility requirements.
               Additional information is available from your financial adviser
               or by calling (800) 257-8787. Your financial adviser can also
               help you prepare any necessary application forms. You or your
               financial adviser must notify Nuveen at the time of each purchase
               if you are eligible for any of these programs. The funds may
               modify or discontinue these programs at any time.

               How to Buy Shares
    
               You may open an account with $3,000 per fund share class and make
               additional investments at any time with as little as $50. There
               is no minimum if you are reinvesting Nuveen Defined Portfolio
               distributions. The share price you pay will depend on when Nuveen
               receives your order. Orders received before the close of trading
               on a business day will receive that day's closing share price,
               otherwise you will receive the next business day's price. A
               business day is any day the New York Stock Exchange is open for
               business and usually ends at 4 p.m. New York time when the
               Exchange closes.

               Through a Financial Adviser

               You may buy shares through your financial adviser, who can handle
               all the details for you, including opening a new account.
               Financial advisers can also help you review your financial needs
               and formulate long-term investment goals and objectives. In
               addition, financial advisers generally can help you develop a
               customized financial plan, select investments and monitor and
               review your portfolio on an ongoing basis to help assure your
               investments continue to meet your needs as circumstances change.
               Financial advisers are paid either from fund sales charges and
               fees or by charging you a separate fee in lieu of a sales charge
               for ongoing investment advice and services. If you do not have a
               financial adviser, call (800) 257-8787 and Nuveen can refer you
               to one in your area.    
    
               By Mail

               You may open an account and buy shares by mail by completing the
               enclosed application and mailing it along with your check to:
               Nuveen Investor Services, P.O. Box 5186, Bowling Green Station,
               New York, NY 10274-5186.     

               Systematic Investing

               Once you have established a fund account, systematic investing
               allows you to make regular investments through automatic
               deductions from your bank account (simply complete the
               appropriate section of the account application form) or directly
               from your paycheck. To invest directly from your paycheck,
               contact your financial adviser or call Nuveen at (800) 257-8787.
               Systematic investing may also make you eligible for reduced sales
               charges.

               The chart below illustrates the benefits of systematic investing
               based on a $3,000 initial investment and subsequent monthly
               investments of $100 over 20 years. The example assumes you earn a
               return of 4%, 5% or 6% annually on your investment and that you
               reinvest all dividends. These annual returns do not reflect past
               or projected fund performance.

24   Section 3   How You Can Buy and Sell Shares
<PAGE>
 
               One of the benefits of systematic investing is dollar cost
               averaging. Because you regularly invest a fixed amount of money
               over a period of years regardless of the share price, you buy
               more shares when the price is low and fewer shares when the price
               is high. As a result, the average share price you pay should be
               less than the average share price of fund shares over the same
               period. To be effective, dollar cost averaging requires that you
               invest over a long period of time, and does not assure that you
               will profit.

               Systematic Investment Plan

               You can make regular investments of $50 or more per month by
               authorizing us to draw preauthorized checks on your bank account.
               You can stop the withdrawals at any time. There is no charge for
               this plan.

               Payroll Direct Deposit Plan

               You can, with your employer's consent, make regular investments
               of $25 or more per pay period (meeting the monthly minimum of
               $50) by authorizing your employer to deduct this amount
               automatically from your paycheck. You can stop the deductions at
               any time. There is no charge for this plan.

               Systematic Withdrawal

               If the value of your fund account is at least $10,000, you may
               request to have $50 or more withdrawn automatically from your
               account. You may elect to receive payments monthly, quarterly,
               semi-annually or annually, and may choose to receive a check,
               have the monies transferred directly into your bank account (see
               "Fund Direct--Electronic Funds Transfer" below), paid to a third
               party or sent payable to you at an address other than your
               address of record. You must complete the appropriate section of
               the account application or Account Update Form to participate in
               the fund's systematic withdrawal plan.

               You should not establish systematic withdrawals if you intend to
               make concurrent purchases of Class A, B or C shares because you
               may unnecessarily pay a sales charge or CDSC on these purchases.

               Special Services

               To help make your investing with us easy and efficient, we offer
               you the following services at no extra cost.

    
               Exchanging Shares

               You may exchange fund shares into an identically registered
               account at any time for the same class of another Nuveen mutual
               fund available in your state. Your exchange must meet the minimum
               purchase requirements of the fund into which you are exchanging.
               Because an exchange is treated for tax purposes as a concurrent
               sale and purchase, and any gain may be subject to tax, you should
               consult your tax adviser about the tax consequences of any
               contemplated exchange.     

               The exchange privilege is not intended to allow you to use a fund
               for short-term trading. Because excessive exchanges may interfere
               with portfolio management, raise fund operating expenses or
               otherwise have

                                  Section 3  How You Can Buy and Sell Shares  25
<PAGE>
 
     
               an adverse effect on other shareholders, each fund reserves the
               right to revise or suspend the exchange privilege, limit the
               amount or number of exchanges, or reject any exchange.     

               Reinstatement Privilege

               If you redeem fund shares, you may reinvest all or part of your
               redemption proceeds up to one year later without incurring any
               additional charges. You may only reinvest into the same share
               class you redeemed. If you paid a CDSC, we will refund your CDSC
               and reinstate your holding period. You may use this reinstatement
               privilege only once for any redemption.

               Fund Direct
    
               You may link your fund account to your bank account and transfer
               money electronically between these accounts and perform a variety
               of account transactions, including buying shares by telephone and
               systematic investment. You may also have dividends,
               distributions, redemption payments or Systematic Withdrawals sent
               directly to your bank account.     

               Your financial adviser can help you complete the forms for these
               services, or you can call Nuveen at (800) 257-8787 for copies of
               the necessary forms.

               How to Sell Shares
    
               You may use one of the following ways to sell (redeem) your
               shares on any day the New York Stock Exchange is open. You will
               receive the share price next determined after Nuveen has received
               your properly completed redemption request. Your redemption
               request must be received before the close of trading for you to
               receive that day's price. While the funds do not charge a
               redemption fee, you may be assessed a CDSC, if applicable. When
               you redeem Class A, Class B, or Class C shares subject to a CDSC,
               the fund will first redeem any shares that are not subject to a
               CDSC or that represent an increase in the value of your fund
               account due to capital appreciation, and then redeem the shares
               you have owned for the longest period of time, unless you ask the
               fund to redeem your shares in a different order. No CDSC is
               imposed on shares you buy through the reinvestment of dividends
               and capital gains. The holding period is calculated on a monthly
               basis and begins on the first day of the month in which you buy
               shares. When you redeem shares subject to a CDSC, the CDSC is
               calculated on the lower of your purchase price or redemption
               proceeds, deducted from your redemption proceeds, and paid to
               Nuveen. The CDSC may be waived under certain special
               circumstances as described in the Statement of Additional
               Information.     

               Through Your Financial Adviser

               You may sell your shares through your financial adviser who can
               prepare the necessary documentation. Your financial adviser may
               charge for this.

    
               By Telephone

               If you have authorized telephone redemption privileges, you can
               redeem your shares by telephone up to $50,000. You may not redeem
               by telephone shares held in certificate form. Checks will be
               issued only to the shareholder of record and mailed to the
               address of record. If you have established electronic funds
               transfer privileges, you may have redemption proceeds transferred
               electronically to your bank account. We will normally mail your
               check the next business day. Nuveen and Chase Global Funds
               Services will be liable for losses resulting from unauthorized
               telephone redemptions only if they do not follow reasonable
               procedures designed to

               verify the identity of the caller. You should immediately verify
               your trade confirmations when you receive them.

               By Mail
    
               You can sell your shares at any time by sending a written request
               to the appropriate fund, Nuveen Investor Services, P.O. Box 5186,
               Bowling Green Station, New York, NY 10274-5186. Your request must
               include the following information:     

               . The fund's name;

               . Your name and account number;

               . The dollar or share amount you wish to redeem;

               . The signature of each owner exactly as it appears on the
                 account;

               . The name of the person to whom you want your redemption
                 proceeds paid (if other than to the shareholder of record);

               . The address where you want your redemption proceeds sent (if
                 other than the address of record);

               . Any certificates you have for the shares; and

               . Any required signature guarantees.
    
               We will normally mail your check the next business day, but in no
               event more than seven days after we receive your request. If you
               purchased your shares by check, your redemption proceeds will not
               be mailed until your check has cleared. Guaranteed signatures are
               required if you are redeeming more than $50,000, you want the
               check payable to someone other than the shareholder of record or
               you want the check sent to another address (or the address of
               record has been changed within the last 60 days). Signature
               guarantees must be obtained from a bank, brokerage firm or other
               financial intermediary that is a member of an approved Medallion
               Guarantee Program or that is otherwise approved by a fund. A
               notary public cannot provide a signature guarantee.     


AN IMPORTANT NOTE ABOUT INVOLUNTARY REDEMPTION.

    
FROM TIME TO TIME, THE FUNDS MAY ESTABLISH MINIMUM ACCOUNT SIZE REQUIREMENTS. 
THE FUNDS RESERVE THE RIGHT TO LIQUIDATE YOUR ACCOUNT UPON 30 DAYS' WRITTEN 
NOTICE IF THE VALUE OF YOUR ACCOUNT FALLS BELOW AN ESTABLISHED MINIMUM. THE 
FUNDS PRESENTLY HAVE SET A MINIMUM BALANCE OF $100 UNLESS YOU HAVE AN ACTIVE 
NUVEEN DEFINED PORTFOLIO REINVESTMENT ACCOUNT. YOU WILL NOT BE ASSESSED A CDSC 
ON AN INVOLUNTARY REDEMPTION.

Section 4 General Information

          To help you understand the tax implications of investing in the funds,
          this section includes important details about how the funds make
          distributions to shareholders. We discuss some other fund policies, as
          well.

    
          Distributions and Taxes

          The funds pay tax-free dividends monthly and any taxable capital gains
          or other taxable distributions once a year in December. The funds
          declare dividends monthly to shareholders of record as of the ninth of
          each month, payable the first business day of the following 
          month.     

          Payment and Reinvestment Options

          The funds automatically reinvest your dividends in additional fund
          shares unless you request otherwise. You may request to have your
          dividends paid to you by check, deposited directly into your bank
          account, paid to a third party, sent to an address other than your
          address of record or reinvested in shares of another Nuveen mutual
          fund. For further information, contact your financial adviser or call
          Nuveen at (800) 257-8787. 


          Taxes and Tax Reporting 

          Because the funds invest in municipal bonds, the regular monthly
          dividends you receive will be exempt from regular federal income tax.
          All or a portion of these dividends, however, may be subject to state
          and local taxes or to the federal alternative minimum tax (AMT).

          Although the funds do not seek to realize taxable income or capital
          gains, the funds may realize and distribute taxable income or capital
          gains from time to time as a result of each fund's normal investment
          activities. Each fund will distribute in December any taxable income
          or capital gains realized over the preceding year. Net short-term
          gains are taxable as ordinary income. Net long-term capital gains are
          taxable as long-term capital gains regardless of how long you have
          owned your investment. Taxable dividends do not qualify for a
          dividends received deduction if you are a corporate shareholder.

          Early in each year, you will receive a statement detailing the amount
          and nature of all dividends and capital gains, including any
          percentage of your fund dividends attributable to municipal
          obligations, that you were paid during the prior year. You will
          receive this statement from the firm where you purchased your fund
          shares if you hold your investment in street name. Nuveen will send
          you this statement if you hold your shares in registered form. The tax
          status of your dividends is not affected by whether you reinvest your
          dividends or receive them in cash. If you receive social security
          benefits, you should be aware that any tax-free income is taken into
          account in calculating the amount of these benefits that may be
          subject to federal income tax.

28   Section 4   General Information
<PAGE>
 
          Tax laws are subject to change, so we urge you to consult your tax
          adviser about your particular tax situation and how it might be
          affected by current tax law.

          Please note that if you do not furnish us with your correct Social
          Security number or employer identification number, federal law
          requires us to withhold federal income tax from your distributions and
          redemption proceeds at a rate of 31%.

          BUYING OR SELLING SHARES CLOSE TO A RECORD DATE
          Buying fund shares shortly before the record date for a taxable
          dividend is commonly known as "buying the dividend." The entire
          dividend may be taxable to you even though a portion of the dividend
          effectively represents a return of your purchase price. Similarly, if
          you sell or exchange fund shares shortly before the record date for a
          tax-exempt dividend, a portion of the price you receive may be treated
          as a taxable capital gain even though it reflects tax-free income
          earned but not yet distributed by the fund.

          TAXABLE EQUIVALENT YIELDS
          The taxable equivalent yield is the current yield you would need to
          earn on a taxable investment in order to equal a stated tax-free yield
          on a municipal investment. To assist you to more easily compare
          municipal investments like the funds with taxable alternative
          investments, the table below presents the taxable equivalent yields
          for a range of hypothetical tax-free yields and tax rates:

          TAXABLE EQUIVALENT OF TAX-FREE YIELDS                        
          
                                        TAX-FREE YIELD     
          
          Tax Rate                  4.00%     4.50%  5.00%  5.50%  6.00%
          28.0%                     5.56%     6.25%  6.94%  7.64%  8.33%
          31.0%                     5.80%     6.52%  7.25%  7.97%  8.70%
          36.0%                     6.25%     7.03%  7.81%  8.59%  9.37%
          39.6%                     6.62%     7.45%  8.28%  9.11%  9.93%

          The yields and tax rates shown above are hypothetical and do not
          predict your actual returns or effective tax rate. For more detailed
          information, see the statement of additional information or consult
          your tax adviser.

          Distribution and Service Plans

    
          John Nuveen & Co. Incorporated serves as the selling agent and
          distributor of the funds' shares. In this capacity, Nuveen manages the
          offering of the funds' shares and is responsible for all sales and
          promotional activities. In order to reimburse Nuveen for its costs in
          connection with these activities, including compensation paid to
          authorized dealers, each fund has adopted a distribution and service
          plan under Rule 12b-1 under the Investment Company Act of 1940. (See
          "How to Choose a Share Class" for a description of the distribution
          and service fees paid under this plan.)     

    
          Nuveen receives the distribution fee for Class B and Class C shares
          primarily for providing compensation to authorized dealers, including
          Nuveen, in connection with the distribution of shares. Nuveen uses the
          service fee for Class A, Class B, and Class C shares to compensate
          authorized dealers, including Nuveen, for providing account services
          to

          shareholders. These services may include establishing and maintaining
          shareholder accounts, answering shareholder inquiries, and providing
          other personal services to shareholders. These fees also compensate
          Nuveen for other expenses, including printing and distributing
          prospectuses to persons other than shareholders, and preparing,
          printing, and distributing advertising and sales literature and
          reports to shareholders used in connection with the sale of shares.
          Because these fees are paid out of the funds' assets on an on-going
          basis, over time these fees will increase the cost of your investment
          and may cost you more than paying other types of sales charges.     

          Net Asset Value

    
          The price you pay for your shares is based on the fund's net asset
          value per share which is determined as of the close of trading
          (normally 4:00 p.m. eastern time) on each day the New York Stock
          Exchange is open for business. Net asset value is calculated for each
          class by taking the fair value of the class' total assets, including
          interest or dividends accrued but not yet collected, less all
          liabilities, and dividing by the total number of shares outstanding.
          The result, rounded to the nearest cent, is the net asset value per
          share. All valuations are subject to review by the funds' Board of
          Trustees or its delegate.

          In determining net asset value, expenses are accrued and applied daily
          and securities and other assets for which market quotations are
          available are valued at market value. The prices of municipal bonds
          are provided by a pricing service and based on the mean between the
          bid and asked price. When price quotes are not readily available
          (which is usually the case for municipal securities), the pricing
          service establishes fair market value based on prices of comparable
          municipal bonds.     

          Fund Service Providers

          The custodian of the assets of the funds is The Chase Manhattan Bank,
          4 New York Plaza, New York, NY 10004-2413. Chase also provides certain
          accounting services to the funds. The funds' transfer, shareholder
          services and dividend paying agent, Chase Global Funds Services
          Company, P.O. Box 5186, New York, NY 10274-5186, performs bookkeeping,
          data processing and administrative services for the maintenance of
          shareholder accounts.

    
          Nuveen Advisory and Chase Global Funds Services each rely on computer
          systems to manage the funds' investments, process shareholder
          transactions and provide shareholder account maintenance. Because of
          the way computers historically have stored dates, some of these
          systems currently may not be able to correctly process activity
          occurring in the year 2000. Nuveen Advisory is working with the funds'
          service providers to adapt their systems to address this "Year 2000"
          issue. Nuveen advisory and the funds expect, but there can be no
          absolute assurance, that the necessary work will be completed on a
          timely basis.

Appendix  Additional State Information 


          Because the funds primarily purchase municipal bonds from a specific
          state, each fund also bears investment risk from economic, political
          or regulatory changes that could adversely affect municipal bond
          issuers in that state and therefore the value of the fund's investment
          portfolio. The following discussion of special state considerations
          was obtained from official offering statements of these issuers and
          has not been independently verified by the funds. The discussion
          includes general state tax information related to an investment in
          fund shares. Because tax laws are complex and often change, you should
          consult your tax adviser about the state tax consequences of a
          specific fund investment. See the Statement of Additional Information
          for further information.


          KANSAS

          Growth in the State's trade, services and manufacturing sectors has
          decreased the historical dominance of agriculture in the State
          economy. Economic performance has been improving, due largely to gains
          in aircraft manufacturing and recovery in agriculture. Personal income
          grew at 5.4% in 1997 to $24,379, about 95% of the national median.


          The State's unemployment rate dropped to 3.5% in June 1998 from its
          peak of 5.5% in 1993.


          The Kansas State Treasury does not issue general obligation debt. The
          State instead relies on revenue and lease financing through the
          Department of Transportation (KDOT) and the Development Finance
          Authority (KDFA). KDFA provides financing for various public purpose
          projects including prison construction, state offices, energy
          conservation and university facilities. The KDOT bonds are rated
          Aa2/AA+/AA by Moody's, Standard & Poor's, and Fitch respectively. KDFA
          ratings vary and when not insured are generally rated A or better by
          the major rating agencies.

          Tax Treatment

          The Kansas Fund's regular monthly dividends will not be subject to
          Kansas personal income taxes to the extent they are paid out of income
          earned on all Kansas municipal bonds issued after December 31, 1987,
          on specified Kansas municipal bonds issued before that date, or on
          U.S. government securities. You will be subject to Kansas personal
          income taxes, however, to the extent the Kansas Fund distributes any
          taxable income or realized capital gains, or if you sell or exchange
          Kansas Fund shares and realize a capital gain on the transaction.

          The treatment of corporate shareholders of the Kansas Fund is similar
          to that described above.

          KENTUCKY
              
          Growth in Kentucky's economy surpassed national growth rates in many
          areas during the 1990's in part due to its lower cost of living and
          aggressive business recruitment. The Commonwealth's economic base is
          concentrated in manufacturing and service industries such as
          industrial machinery, electronics and apparel production and insurance
          and real estate. Kentucky's "Golden Triangle" bounded by Cincinnati,
          Lexington and Louisville has experienced the most intense economic
          growth.     
              
          Kentucky's average unemployment rate in June 1998 was 4.4%, compared
          to the national average of 4.5% in June 1998 and the Commonwealth's
          5.5% average in June 1997. Per capita income in 1997 was $20,657,
          approximately 81% of national average.     
              
          In the past, the Commonwealth has experienced difficulty balancing its
          budget, but recent economic growth and moderate debt levels improve
          the Commonwealth's financial outlook. Although Kentucky has not issued
          general obligation debt since 1965, the Commonwealth actively issues
          appropriation-secured debt from several agencies, including the
          Kentucky Turnpike Authority, the Kentucky Infrastructure Authority,
          and the Kentucky Schools Facilities Construction Commission. Bonds
          secured by Commonwealth appropriations generally receive ratings of
          "A" or higher from the major rating services. All of Kentucky's
          general obligation debt matured in 1995. Like the Commonwealth,
          Kentucky Municipalities have not issued general obligation debt,
          relying instead on appropriation-secured bonds.     
              
          TAX TREATMENT     
              
          The Kentucky Funds' regular monthly dividends will not be subject to
          the Kentucky individual income tax to the extent they are paid out of
          income earned on Kentucky municipal bonds or U.S. government
          securities. You will be subject to Kentucky personal income tax,
          however, to the extent the Kentucky Funds distribute any taxable
          income or realized capital gains, or if you sell or exchange Kentucky
          Funds' shares and realize a capital gain on the transaction. You will
          not be subject to the Kentucky intangible property tax on the portion
          of your Kentucky Funds' shares that is attributable to Kentucky
          municipal bonds or U.S. government securities.     
              
          If you are employed in Louisville or Jefferson County, you will not be
          subject to local occupational license fees on income earned from the
          Kentucky Funds. If you are employed elsewhere in Kentucky, you
          generally will not be subject to local occupational license fees. The
          treatment of corporate shareholders is similar to that described
          above, except that they may be subject to local occupational license
          fees.     

          MICHIGAN
              
          Michigan's economy has improved significantly since the 1980's. The
          State's unemployment rate was 3.6% in June 1998, compared to national
          average of 4.5%. Per capita income has increased each year over the
          past decade, and was $25,560 in 1997. Population has remained stable
          in the State, increasing by a negligible amount annually. The
          manufacturing industry and the presence of the "Big 3" automobile
          manufacturers are the primary influence in the economy. Despite recent
          strikes and lower automobile sales and profits, the positive economic
          impact of the manufacturing industry has contributed to the tax base
          and job growth.     
              
                                                                     Appendix 39
                                                                                
<PAGE>
 
              
          Michigan's economic and financial improvements are reflected in the
          state's rating of Aa1/AA+/AA+ by Moody's, Standard & Poor's and Fitch,
          respectively. All three rating agencies upgraded the State's credit
          rating in 1998.     
              
          TAX TREATMENT     
              
          The Michigan Fund's regular monthly dividends will not be subject to
          the Michigan individual income tax to the extent they are paid out of
          income earned on Michigan municipal bonds or paid out of income earned
          on or capital gains realized from, the sale of U.S. government
          securities. You will be subject to Michigan personal income tax,
          however, to the extent the Michigan Fund distributes any taxable
          income or realized capital gains (other than capital gains realized
          from the sale of U.S. government securities), or if you sell or
          exchange Michigan Fund shares and realize a capital gain on the
          transaction. If you reside in a Michigan city that imposes local
          income taxes, you will not be subject to these taxes on the Michigan
          Fund's distributions of income attributable to interest earned on U.S.
          government securities or municipal bonds, or to gains on the sale of
          U.S. government securities.     
              
          The treatment of corporate shareholders of the Michigan Fund differs
          from that described above. Corporate shareholders should refer to the
          Statement of Additional Information for more detailed 
          information.     

          MISSOURI
              
          Missouri maintains a diversified economy, mirroring that of the
          nation. Although recent industry growth has shifted to services and
          tourism, defense and manufacturing are important elements of the State
          economy. Population in Missouri has increased approximately 5.6% from
          1990. The State's unemployment rate has steadily declined from the
          high of 6.7% in 1991 and was 4.2% in June 1998, compared to the
          national average of 4.5%. Per capita income increased 4.4% during 1997
          to $24,001, about 94% of the national average.     
              
          Missouri retains substantial governmental balances through strategic
          budget management. The State's unreserved fund balance in 1997 was
          $1.2 billion, or 12.4% of General Fund revenues. Missouri's overall
          creditworthiness is reflected in its longstanding Aaa/AAA/AAA rating
          by Moody's Standard & Poors, and Fitch, respectively.     
              
          TAX TREATMENT     

          The Missouri Fund's regular monthly dividends will not be subject to
          the Missouri individual income tax to the extent they are paid out of
          income earned on Missouri municipal bonds or U.S. government
          securities. You will be subject to Missouri personal income tax,
          however, to the extent the Missouri Fund distributes any taxable
          income or realized capital gains, or if you sell or exchange Missouri
          Fund shares and realize a capital gain on the transaction.

          The treatment of corporate shareholders of the Missouri Fund is
          similar to that described above.

          OHIO

          The Ohio economy has historically relied on durable goods
          manufacturing, but recent growth has brought healthy diversification.
          Employment growth in recent years has been concentrated among non-
          manufacturing industries, with manufacturing employment tapering off
          since its 1969 peak. Still, manufacturing remains an important
          component of the State's economy, providing approximately 21% of total
          employment in Ohio compared with 15% of national employment. General
          economic activity in Ohio tends to be more cyclical than in non-
          industrialized states, but during the current national expansion it
          has had positive implications in Ohio. 

          From 1990-1998, the State's unemployment rate ranked at or below the
          national average. Ohio's unemployment rate registered 4.5% in June
          1998, comparable to the national average of 4.5% in June 1998, and
          slightly higher than the State's 4.4% rate in June 1997. Per capita
          income in 1997 was $24,661, approximately 96% of the national average.

          The State cannot by law operate with a deficit and has well-
          established procedures to ensure that appropriations and expenditures
          are matched by revenues from the General Revenue Fund. The State is
          currently working on revamping its school funding formula, which was
          deemed unconstitutional in March 1997 by the Ohio Supreme Court.
          Changes to the formula likely will require the State to increase its
          aid to local public schools, which could affect the State's financial
          position. Moody's gives Ohio general obligation bonds an Aa1 rating,
          while Standard & Poor's and Fitch each rate the State AA+.

          TAX TREATMENT

          The Ohio Fund's regular monthly dividends will not be subject to Ohio
          personal income tax, Ohio school district income taxes and Ohio
          municipal income taxes to the extent they are derived from interest on
          Ohio municipal bonds or U.S. government securities or attributable to
          gain made on the sale, exchange or other disposition by the Fund of
          Ohio municipal bonds. You will, however, be subject to Ohio personal
          income taxes, Ohio school district income taxes and Ohio municipal
          income taxes to the extent the Ohio Fund distributes any taxable
          income or realized capital gains (other than capital gains on Ohio
          municipal bonds), or if you sell or exchange Ohio Fund shares and
          realize a net gain on the transaction.

          The treatment of corporate shareholders of the Ohio Fund differs from
          that described above. Corporate shareholders should refer to the
          Statement of Additional Information for more detailed information and
          are urged to consult their tax adviser.

          WISCONSIN

          Wisconsin's economy is diverse and strong with non-agricultural
          employment evenly spread between the manufacturing, service and trade
          sectors. The State continues its efforts to attract new businesses
          with grants and loans for major development projects, labor training
          and technology development. Manufacturing remains a dominant sector at
          24% and is currently a source of strength.

                                                                     Appendix 41
<PAGE>
 
          The State's unemployment rate was 3.0% in June 1998. Per capita
          income was $24,475 in 1997, about 96% of the national average.

          The State's general obligations receive Aa2/AA ratings from Moody's
          and Standard and Poor's, respectively.

          TAX TREATMENT

          The Wisconsin Fund's regular monthly dividends will not be subject to
          Wisconsin personal income tax to the extent they are paid out of
          income earned on certain Wisconsin municipal obligations or on U.S.
          government securities. You will be subject to Wisconsin personal
          income tax, to the extent the Wisconsin Fund distributes any taxable
          income or realized capital gains, or if you sell or exchange Wisconsin
          Fund shares and realize capital gains on the transaction. A certain
          portion of such capital gains, however, will be exempt from Wisconsin
          personal income tax.

          The treatment of corporate shareholders of the Wisconsin Fund differs
          from that described above. Corporate shareholders should refer to the
          Statement of Additional Information for more detailed information and
          are urged to consult their tax adviser.

INVESTMENT POLICIES AND INVESTMENT PORTFOLIO
 
INVESTMENT POLICIES
 
  The investment objective and certain fundamental investment policies of each
Fund are described in the Prospectus. Each of the Funds, as a fundamental
policy, may not, without the approval of the holders of a majority of the
shares of that Fund:
 
    (1) Invest in securities other than Municipal Obligations and short-term
  securities, as described in the Prospectus. Municipal Obligations are
  municipal bonds that pay interest that is exempt from regular federal,
  state and, in some cases, local income taxes.
 
    (2) Invest more than 5% of its total assets in securities of any one
  issuer, except this limitation shall not apply to securities of the United
  States Government, and to the investment of 25% of such Fund's assets. This
  limitation shall apply only to the Kentucky Municipal Bond Fund, the
  Michigan Municipal Bond Fund, and the Ohio Municipal Bond Fund.
 
    (3) Borrow money, except from banks for temporary or emergency purposes
  and not for investment purposes and then only in an amount not exceeding
  (a) 10% of the value of its total assets at the time of borrowing or (b)
  one-third of the value of the Fund's total assets including the amount
  borrowed, in order to meet redemption requests which might otherwise
  require the untimely disposition of securities. While any such borrowings
  exceed 5% of such Fund's total assets, no additional purchases of
  investment securities will be made by such Fund. If due to market
  fluctuations or other reasons, the value of the Fund's assets falls below
  300% of its borrowings, the Fund will reduce its borrowings within 3
  business days. To do this, the Fund may have to sell a portion of its
  investments at a time when it may be disadvantageous to do so.
 
    (4) Pledge, mortgage or hypothecate its assets, except that, to secure
  borrowings permitted by subparagraph (2) above, it may pledge securities
  having a market value at the time of pledge not exceeding 10% of the value
  of the Fund's total assets.
 
    (5) Issue senior securities as defined in the Investment Company Act of
  1940, except to the extent such issuance might be involved with respect to
  borrowings described under item (3) above or with respect to transactions
  involving futures contracts or the writing of options within the limits
  described in the Prospectus and this Statement of Additional Information.
 
    (6) Underwrite any issue of securities, except to the extent that the
  purchase or sale of Municipal Obligations in accordance with its investment
  objective, policies and limitations, may be deemed to be an underwriting.
 
    (7) Purchase or sell real estate, but this shall not prevent any Fund
  from investing in Municipal Obligations secured by real estate or interests
  therein or foreclosing upon and selling such security.
 
    (8) Purchase or sell commodities or commodities contracts or oil, gas or
  other mineral exploration or development programs, except for transactions
  involving futures contracts within the limits described in the Prospectus
  and this Statement of Additional Information.
 
    (9) Make loans, other than by entering into repurchase agreements and
  through the purchase of Municipal Obligations or temporary investments in
  accordance with its investment objective, policies and limitations.
 
 
                                      S-2
<PAGE>
 
    (10) Make short sales of securities or purchase any securities on margin,
  except for such short-term credits as are necessary for the clearance of
  transactions.
 
    (11) Write or purchase put or call options, except to the extent that the
  purchase of a stand-by commitment may be considered the purchase of a put,
  and except for transactions involving options within the limits described
  in the Prospectus and this Statement of Additional Information.
 
    (12) Invest more than 25% of its total assets in securities of issuers in
  any one industry; provided, however, that such limitations shall not be
  applicable to Municipal Obligations issued by governments or political
  subdivisions of governments, and obligations issued or guaranteed by the
  U.S. Government, its agencies or instrumentalities.
 
    (13) Purchase or retain the securities of any issuer other than the
  securities of the Fund if, to the Fund's knowledge, those trustees of the
  Trust, or those officers and directors of Nuveen Advisory Corp. ("Nuveen
  Advisory"), who individually own beneficially more than 1/2 of 1% of the
  outstanding securities of such issuer, together own beneficially more than
  5% of such outstanding securities.
 
  In addition, each Fund, as a non-fundamental policy, may not invest more than
15% of its net assets in "illiquid" securities, including repurchase agreements
maturing in more than seven days.
 
  For the purpose of applying the limitations set forth in paragraph (2) above,
an issuer shall be deemed the sole issuer of a security when its assets and
revenues are separate from other governmental entities and its securities are
backed only by its assets and revenues. Similarly, in the case of a non-
governmental user, such as an industrial corporation or a privately owned or
operated hospital, if the security is backed only by the assets and revenues of
the non-governmental user, then such non-governmental user would be deemed to
be the sole issuer. Where a security is also backed by the enforceable
obligation of a superior or unrelated governmental entity or other entity
(other than a bond insurer), it shall also be included in the computation of
securities owned that are issued by such governmental or other entity.
 
  Where a security is guaranteed by a governmental entity or some other
facility, such as a bank guarantee or letter of credit, such a guarantee or
letter of credit would be considered a separate security and would be treated
as an issue of such government, other entity or bank. Where a security is
insured by bond insurance, it shall not be considered a security issued or
guaranteed by the insurer; instead the issuer of such security will be
determined in accordance with the principles set forth above. The foregoing
restrictions do not limit the percentage of the Fund's assets that may be
invested in securities insured by any single insurer.
 
  The foregoing restrictions and limitations, as well as a Fund's policies as
to ratings of portfolio investments, will apply only at the time of purchase of
securities, and the percentage limitations will not be considered violated
unless an excess or deficiency occurs or exists immediately after and as a
result of an acquisition of securities, unless otherwise indicated.
 
  The foregoing fundamental investment policies, together with the investment
objective of each Fund, cannot be changed without approval by holders of a
"majority of the Fund's outstanding voting shares." As defined in the
Investment Company Act of 1940, this means the vote of (i) 67% or more of the
Fund's shares present at a meeting, if the holders of more than 50% of the
Fund's shares are present or represented by proxy, or (ii) more than 50% of the
Fund's shares, whichever is less.
 
  The Nuveen Flagship Multistate Trust IV (the "Trust") is an open-end
management series investment company organized as a Massachusetts business
trust on July 1, 1996. Each of the Funds is an open-end management investment
company organized as a series of the Nuveen Flagship Multistate Trust IV. The
Trust is
 
                                      S-3
<PAGE>
 
an open-end management series company under SEC Rule 18f-2. Each Fund is a
separate series issuing its own shares. The Trust currently has seven series:
the Nuveen Flagship Kansas Municipal Bond Fund (formerly the Flagship Kansas
Triple Tax Exempt Fund, a series of the Flagship Tax Exempt Funds Trust); the
Nuveen Flagship Kentucky Municipal Bond Fund (formerly the Flagship Kentucky
Triple Tax Exempt Fund, a series of the Flagship Tax Exempt Funds Trust); the
Nuveen Flagship Kentucky Limited Term Municipal Bond Fund (formerly the
Flagship Kentucky Limited Term Municipal Bond Fund, a series of the Flagship
Tax Exempt Funds Trust); the Nuveen Flagship Michigan Municipal Bond Fund
(formerly the Flagship Michigan Triple Tax Exempt Fund, a series of the
Flagship Tax Exempt Funds Trust); the Nuveen Flagship Missouri Municipal Bond
Fund (formerly the Flagship Missouri Double Tax Exempt Fund, a series of the
Flagship Tax Exempt Funds Trust); the Nuveen Flagship Ohio Municipal Bond Fund
(formerly the Flagship Ohio Double Tax Exempt Fund, a series of the Flagship
Tax Exempt Funds Trust); and the Nuveen Flagship Wisconsin Municipal Bond Fund
(formerly the Flagship Wisconsin Double Tax Exempt Fund, a series of the
Flagship Tax Exempt Funds Trust). Certain matters under the Investment Company
Act of 1940 which must be submitted to a vote of the holders of the outstanding
voting securities of a series company shall not be deemed to have been
effectively acted upon unless approved by the holders of a majority of the
outstanding voting securities of each Fund affected by such matter.
 
  The Trust is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders of a trust may, under
certain circumstances, be held personally liable as partners for its
obligations. However, the Declaration of Trust contains an express disclaimer
of shareholder liability for acts or obligations of the Trust and requires that
notice of this disclaimer be given in each agreement, obligation or instrument
entered into or executed by the Trust or the Trustees. The Declaration of Trust
further provides for indemnification out of the assets and property of the
Trust for all loss and expense of any shareholder personally liable for the
obligations of the Trust. Thus, the risk of a shareholder incurring financial
loss on account of shareholder liability is limited to circumstances in which
both inadequate insurance existed and the Trust itself were unable to meet its
obligations. The Trust believes the likelihood of these circumstances is
remote.
 
PORTFOLIO SECURITIES
 
  As described in the Prospectus, each of the Funds invests substantially all
of its assets (at least 80%) in a portfolio of Municipal Obligations free from
regular federal, state and, in some cases, local income tax in each Fund's
respective state, which generally will be Municipal Obligations issued within
the Fund's respective state. In general, Municipal Obligations include debt
obligations issued by states, cities and local authorities to obtain funds for
various public purposes, including construction of a wide range of public
facilities such as airports, bridges, highways, hospitals, housing, mass
transportation, schools, streets and water and sewer works. Industrial
development bonds and pollution control bonds that are issued by or on behalf
of public authorities to finance various privately-rated facilities are
included within the term Municipal Obligations if the interest paid thereon is
exempt from federal income tax.
 
  The investment assets of each Fund will consist of (1) Municipal Obligations
which are rated at the time of purchase within the four highest grades (Baa or
BBB or better) by Moody's Investors Service, Inc. ("Moody's"), by Standard and
Poor's Corporation ("S&P") or by Fitch Investors Service, Inc. ("Fitch"), (2)
unrated Municipal Obligations which, in the opinion of Nuveen Advisory, have
credit characteristics equivalent to bonds rated within the four highest grades
by Moody's, S&P or Fitch, and (3) temporary investments as described below, the
income from which may be subject to state income tax or to both federal and
state income taxes. See Appendix A for more information about ratings by
Moody's, S&P, and Fitch.
 
 
                                      S-4
<PAGE>
 
  As described in the Prospectus, each Fund may invest in Municipal Obligations
that constitute participations in a lease obligation or installment purchase
contract obligation (hereafter collectively called "lease obligations") of a
municipal authority or entity. Although lease obligations do not constitute
general obligations of the municipality for which the municipality's taxing
power is pledged, a lease obligation is ordinarily backed by the municipality's
covenant to budget for, appropriate and make the payments due under the lease
obligation. However, certain lease obligations contain "non-appropriation"
clauses which provide that the municipality has no obligation to make lease or
installment purchase payments in future years unless money is appropriated for
such purpose on a yearly basis. Although nonappropriation lease obligations are
secured by the leased property, disposition of the property in the event of
foreclosure might prove difficult. A Fund will seek to minimize the special
risks associated with such securities by only investing in those
nonappropriation leases where Nuveen Advisory has determined that the issuer
has a strong incentive to continue making appropriations and timely payment
until the security's maturity. Some lease obligations may be illiquid under
certain circumstances. Lease obligations normally provide a premium interest
rate which along with regular amortization of the principal may make them
attractive for a portion of the assets of the Funds.
 
  Obligations of issuers of Municipal Obligations are subject to the provisions
of bankruptcy, insolvency and other laws affecting the rights and remedies of
creditors. In addition, the obligations of such issuers may become subject to
the laws enacted in the future by Congress, state legislatures or referenda
extending the time for payment of principal and/or interest, or imposing other
constraints upon enforcement of such obligations or upon municipalities to levy
taxes. There is also the possibility that, as a result of legislation or other
conditions, the power or ability of any issuer to pay, when due, the principal
of and interest on its Municipal Obligations may be materially affected.
 
YEAR 2000 ISSUES
 
  The "Year 2000" problem refers to the fact that many computer programs use
only the last two digits of a year, and do not recognize a year that begins
with "20" instead of "19." If this problem is not corrected, computers could
function improperly or not at all, which could affect the global economy. The
SEC has urged securities issuers to disclose the steps they are taking to
correct any Year 2000 problems.
 
  The Funds invest primarily in municipal securities. If municipal issuers do
not correct any Year 2000 problems in a timely manner, they could experience
problems in conducting their operations or in making payments on their
securities, which could cause the value of these securities to decline.
Municipal issuers could experience three types of Year 2000 problems. First, if
an issuer's internal computer systems experience Year 2000 problems, this could
disrupt an issuer's operations (such as its ability to collect local taxes or
fees). Second, an issuer may rely on other parties for the payments that
support its debt service, such as servicers that collect mortgage or student
loan payments, and those third parties may have Year 2000 problems that
interfere with their ability to forward payments to the issuer. Third, an
issuer may have mechanical problems in sending payments to its securities
holders.
 
  Nuveen Advisory is obtaining information about the Year 2000 readiness of the
issuers of its portfolio securities as part of its ongoing surveillance of the
creditworthiness of those issuers.
 
PORTFOLIO TRADING AND TURNOVER
 
  The Funds will make changes in their investment portfolio from time to time
in order to take advantage of opportunities in the municipal market and to
limit exposure to market risk. The Funds may also engage to a limited extent in
short-term trading consistent with their investment objective. Securities may
be sold in anticipation of market decline or purchased in anticipation of
market rise and later sold. In addition, a security may be sold and another of
comparable quality purchased at approximately the same time to take advantage
of what Nuveen Advisory believes to be a temporary disparity in the normal
yield relationship between the two
 
                                      S-5
<PAGE>
 
securities. Each Fund may make changes in its investment portfolio in order to
limit its exposure to changing market conditions. Changes in a Fund's
investments are known as "portfolio turnover." While it is impossible to
predict future portfolio turnover rates, the annual portfolio turnover rate for
each of the Funds is generally not expected to exceed 75%. However, each Fund
reserves the right to make changes in its investments whenever it deems such
action advisable and, therefore, a Fund's annual portfolio turnover rate may
exceed 75% in particular years depending upon market conditions.
 
The portfolio turnover rates for the 1997 and 1998 fiscal years for the Funds
were:

WHEN-ISSUED SECURITIES
 
  Each Fund may purchase and sell Municipal Obligations on a when-issued or
delayed delivery basis. When-issued and delayed delivery transactions arise
when securities are purchased or sold with payment and delivery beyond the
regular settlement date. (When-issued transactions normally settle within 15-45
days.) On such transactions the payment obligation and the interest rate are
fixed at the time the buyer enters into the commitment. The commitment to
purchase securities on a when-issued or delayed delivery basis may involve an
element of risk because the value of the securities is subject to market
fluctuation, no interest accrues to the purchaser prior to settlement of the
transaction, and at the time of delivery the market value may be less than
cost. At the time a Fund makes the commitment to purchase a Municipal
Obligation on a when-issued or delayed delivery basis, it will record the
transaction and reflect the amount due and the value of the security in
determining its net asset value. Likewise, at the time a Fund makes the
commitment to sell a Municipal Obligation on a delayed delivery basis, it will
record the transaction and include the proceeds to be received in determining
its net asset value; accordingly, any fluctuations in the value of the
Municipal Obligation sold pursuant to a delayed delivery commitment are ignored
in calculating net asset value so long as the commitment remains in effect. The
Funds will maintain designated readily marketable assets at least equal in
value to commitments to purchase when-issued or delayed delivery securities,
such assets to be segregated by the Custodian specifically for the settlement
of such commitments. The Funds will only make commitments to purchase Municipal
Obligations on a when-issued or delayed delivery basis with the intention of
actually acquiring the securities, but the Funds reserve the right to sell
these securities before the settlement date if it is deemed advisable. If a
when-issued security is sold before delivery any gain or loss would not be tax-
exempt. The Funds commonly engage in when-issued transactions in order to
purchase or sell newly-issued Municipal Obligations, and may engage in delayed
delivery transactions in order to manage operations more effectively.
 
SPECIAL CONSIDERATIONS RELATING TO MUNICIPAL OBLIGATIONS OF DESIGNATED STATES
 
  As described in the Prospectus, except for investments in temporary
investments, each of the Funds will invest substantially all of its assets (at
least 80%) in municipal bonds that are exempt from federal and state tax in
that state ("Municipal Obligations"), generally Municipal Obligations issued in
its respective state. Each Fund is therefore more susceptible to political,
economic or regulatory factors adversely affecting issuers of Municipal
Obligations in its state. Brief summaries of these factors are contained in the
Prospectus. Set forth below is
 
                                      S-6
<PAGE>
 
additional information that bears upon the risk of investing in Municipal
Obligations issued by public authorities in the states of currently offered
Funds. This information was obtained from official statements of issuers
located in the respective states as well as from other publicly available
official documents and statements. The Funds have not independently verified
any of the information contained in such statements and documents. The
information below is intended only as a general summary, and is not intended as
a discussion of any specific factor that may affect any particular obligation
or issuer.
 
FACTORS PERTAINING TO KANSAS
 
  Growth in the State's trade, services and manufacturing sectors has decreased
the historical dominance of agriculture in the State economy. Economic
performance has been improving due largely to gains in aircraft manufacturing
and recovery in agriculture. Personal income grew at 5.4% in 1997 to $24,379,
after posting a 5.7% gain in 1996. Per capita income stands at about 95% of the
national median.
 
  The State's unemployment rate dropped to 3.5% in June 1998 from its peak of
5.5% in 1993.
 
  The Kansas State Treasury does not issue general obligation debt. The state
instead relies on revenue and lease financing through the Department of
Transportation (KDOT) and the Development Finance Authority (KDFA). KDFA is the
conduit for most state debt and provides financing for various public purpose
projects including prison construction, state offices, energy conservation and
university facilities. The KDOT bonds are rated Aa2/AA+/AA from Moody's,
Standard & Poor's, and Fitch, respectively. KDFA ratings vary according to the
underlying purpose and when not insured are generally rated A or better by the
major rating agencies.
 
FACTORS PERTAINING TO KENTUCKY
 
  Growth in Kentucky's economy surpassed national growth rates in many areas
during the 1990's in part due to its lower cost of living and aggressive
business recruitment. The Kentucky economy has continued to prosper under the
same favorable circumstances that have propelled the national economy. The
State's economic base is concentrated in manufacturing and service industries
such as industrial machinery, electronics and apparel production and insurance
and real estate. Kentucky's "Golden Triangle" bounded by Cincinnati, Lexington
and Louisville has experienced the most intense economic growth. The strong
growth in Kentucky's economy is expected to continue, although at a slightly
more moderate rate.
 
  Kentucky's average unemployment rate in June 1998 was 4.4%, compared to the
national average of 4.5% in June 1998 and the State's 5.5% average in June
1997. Per capita income in 1997 was $20,657, approximately 81% of the national
average.
 
  In the past, the State has experienced difficulty balancing its budget, but
recent economic growth and moderate debt levels improve the Commonwealth's
financial outlook. General Fund revenues that exceeded projections and
expenditures that remained within the budget enabled the State to maintain its
Reserve Trust Fund balance of $200 million in fiscal 1997. Although Kentucky
has not issued general obligation debt since 1965, the State actively issues
appropriation-secured debt from several agencies, including the Kentucky
Turnpike Authority, the Kentucky Infrastructure Authority, and the Kentucky
Schools Facilities Construction Commission. Bonds secured by Commonwealth
appropriations generally receive ratings of "A" or higher from the major rating
services. All of Kentucky's general obligation debt matured in 1995. Like the
State, Kentucky municipalities have not issued general obligation debt, relying
instead on appropriation-secured bonds.
 
FACTORS PERTAINING TO MICHIGAN
 
  Michigan's economy has improved significantly since the 1980's. The State's
unemployment rate was 3.6% in June 1998, compared to the national average of
4.5%. Michigan's per capita income has increased each year over the past
decade, surpassing that of the nation's in 1994 after years of lagging the
national average. 1997 per
 
                                      S-7
<PAGE>
 
capita income was $25,560. Population has remained stable in the State,
increasing by a negligible amount annually.
 
  The manufacturing industry and the presence of the "Big 3" automobile
manufacturers are the primary influence in the economy. Despite recent strikes
and lower automobile sales and profits, the positive economic impact of the
manufacturing industry has contributed to the tax base and job growth.
 
  Education in Michigan is a top priority. One of the state's most significant
achievements was the enactment of Proposal A in 1994. To promote equality among
school districts of varying wealth levels, funding for Michigan school
districts shifted from local property taxes to state sales taxes. According to
the fiscal year 1999 budget, no district will enjoy per pupil spending below
$5,170, compared to an average spending of $5,090 per pupil prior to reform.
 
  Michigan's economic and financial improvements are reflected in the state's
rating of Aa1/AA+/AA+ by Moody's, Standard & Poor's and Fitch, respectively.
All three rating agencies upgraded the State's credit rating in 1998.
 
FACTORS PERTAINING TO MISSOURI
 
  Missouri maintains a diversified economy, mirroring that of the nation.
Although recent industry growth has shifted to services and tourism, defense
and manufacturing are important elements of the state economy. McDonnell
Douglas Corporation, one of the largest private employers in the state, employs
approximately 25,000 people, with Chrysler and Ford each employing
approximately 10,000 people.
 
  Population in Missouri has increased approximately 5.6% from 1990. The
State's unemployment rate has steadily declined since the high of 6.7% in 1991
and was 4.2% in June 1998, compared to the national average of 4.5%. Per capita
income increased 4.4% during 1997 to $24,001, which is about 94% of the
national average.
 
  Missouri retains substantial governmental balances through strategic budget
management. The State's unreserved fund balance in 1997 was $1.2 billion, or
12.4% of General Fund revenues. Missouri's overall creditworthiness is
reflected in its long-standing Aaa/AAA/AAA rating by Moody's, S&P, and Fitch,
respectively.
 
FACTORS PERTAINING TO OHIO
 
  The Ohio economy has historically relied on durable goods manufacturing, but
recent growth has brought healthy diversification. Employment growth in recent
years has been concentrated among non-manufacturing industries, with
manufacturing employment tapering off since its 1969 peak. Still manufacturing
remains an important component of the State's economy, providing approximately
21% of total employment in Ohio compared with 15% of national employment.
General economic activity in Ohio tends to be more cyclical than in non-
industrialized states, but during the current national expansion it has had
positive implications in Ohio.
 
  From 1990 to 1998, the State's unemployment rate ranked at or below the
national average. Ohio's unemployment rate registered 4.5% in June 1998,
comparable to the national average of 4.5% in June 1998 and slightly higher
than the State's 4.4% rate in June 1997. Per capita income in 1997 was $24,661,
approximately 96% of the national average.
 
  The State cannot by law operate with a deficit and has well-established
procedures to ensure that appropriations and expenditures are matched by
revenues from the General Revenue Fund. Recently, as a result of the State's
strong economic performance and its financial management practices, the State
has been able to accumulate sizable financial reserves that should help it
address potential cyclical fluctuations. The State is
 
                                      S-8
<PAGE>
 
currently working on revamping its school funding formula, which was deemed
unconstitutional in March 1997
by the Ohio Supreme Court. Changes to the formula will likely require the State
to increase its aid to local public schools, which could affect the State's
financial position. Moody's gives Ohio general obligation bonds an Aa1 rating,
while Standard & Poor's and Fitch each rate the State AA+.
 
FACTORS PERTAINING TO WISCONSIN
 
  Wisconsin's economy is diverse and strong with non-agricultural employment
evenly spread between the manufacturing, service and trade sectors. The State
continues its efforts to attract new businesses with grants and loans for major
development projects, labor training and technology development. Manufacturing
remains a dominant sector at 24% and is currently a source of strength.
 
  The State's unemployment rate was 3.0% in June 1998. Per capita income was
$24,475 in 1997, which is about 96% of the national average.
 
  The State's general obligations receive Aa2/AA ratings from Moody's and
Standard and Poors, respectively.
 
HEDGING AND OTHER DEFENSIVE ACTIONS
 
  Each Fund may periodically engage in hedging transactions. Hedging is a term
used for various methods of seeking to preserve portfolio capital value of
offsetting price changes in one investment through making another investment
whose price should tend to move in the opposite direction. It may be desirable
and possible in various market environments to partially hedge the portfolio
against fluctuations in market value due to interest rate fluctuations by
investment in financial futures and index futures as well as related put and
call options on such instruments. Both parties entering into an index or
financial futures contract are required to post an initial deposit of 1% to 5%
of the total contract price. Typically, option holders enter into offsetting
closing transactions to enable settlement in cash rather than take delivery of
the position in the future of the underlying security. Each Fund will only sell
covered futures contracts, which means that the Fund segregates assets equal to
the amount of the obligations.
 
  These transactions present certain risks. In particular, the imperfect
correlation between price movements in the futures contract and price movements
in the securities being hedged creates the possibility that losses on the hedge
by a Fund may be greater than gains in the value of the securities in such
series, portfolio. In addition, futures and options markets may not be liquid
in all circumstances. As a result, in volatile markets, a Fund may not be able
to close out the transaction without incurring losses substantially greater
than the initial deposit. Finally, the potential daily deposit requirements in
futures contracts create an ongoing greater potential financial risk than do
options transactions, where the exposure is limited to the cost of the initial
premium. Losses due to hedging transactions will reduce yield. Net gains, if
any, from hedging and other portfolio transactions will be distributed as
taxable distributions to shareholders.
 
  No Fund will make any investment (whether an initial premium or deposit or a
subsequent deposit) other than as necessary to close a prior investment if,
immediately after such investment, the sum of the amount of its premiums and
deposits would exceed 5% of such series' net assets. Each series will invest in
these instruments only in markets believed by the investment adviser to be
active and sufficiently liquid. For further information regarding these
investment strategies and risks presented thereby, see Appendix B to this
Statement of Additional Information.
 
  Each Fund reserves the right for liquidity or defensive purposes (such as
thinness in the market for municipal securities or an expected substantial
decline in value of long-term obligations), to temporarily invest up to 20% of
its assets in obligations issued or guaranteed by the U.S. Government and its
agencies or
 
                                      S-9
<PAGE>
 
instrumentalities, including up to 5% in adequately collateralized repurchase
agreements relating thereto. Interest on each instrument is taxable for Federal
income tax purposes and would reduce the amount of tax-free interest payable to
shareholders.
 
TEMPORARY INVESTMENTS
 
  The Prospectus discusses briefly the ability of the Funds to invest a portion
of their assets in federally tax-exempt or taxable "temporary investments."
Temporary investments will not exceed 20% of a Fund's assets except when made
for defensive purposes. The Funds will invest only in taxable temporary
investments that are either U.S. Government securities or are rated within the
highest grade by Moody's, S&P, or Fitch and mature within one year from the
date of purchase or carry a variable or floating rate of interest. See Appendix
A for more information about ratings by Moody's, S&P, and Fitch.
 
  The Funds may invest in the following federally tax-exempt temporary
investments:
 
    Bond Anticipation Notes (BANs) are usually general obligations of state
  and local governmental issuers which are sold to obtain interim financing
  for projects that will eventually be funded through the sale of long-term
  debt obligations or bonds. The ability of an issuer to meet its obligations
  on its BANs is primarily dependent on the issuer's access to the long-term
  municipal bond market and the likelihood that the proceeds of such bond
  sales will be used to pay the principal and interest on the BANs.
 
    Tax Anticipation Notes (TANs) are issued by state and local governments
  to finance the current operations of such governments. Repayment is
  generally to be derived from specific future tax revenues. Tax anticipation
  notes are usually general obligations of the issuer. A weakness in an
  issuer's capacity to raise taxes due to, among other things, a decline in
  its tax base or a rise in delinquencies, could adversely affect the
  issuer's ability to meet its obligations on outstanding TANs.
 
    Revenue Anticipation Notes (RANs) are issued by governments or
  governmental bodies with the expectation that future revenues from a
  designated source will be used to repay the notes. In general, they also
  constitute general obligations of the issuer. A decline in the receipt of
  projected revenues, such as anticipated revenues from another level of
  government, could adversely affect an issuer's ability to meet its
  obligations on outstanding RANs. In addition, the possibility that the
  revenues would, when received, be used to meet other obligations could
  affect the ability of the issuer to pay the principal and interest on RANs.
 
    Construction Loan Notes are issued to provide construction financing for
  specific projects. Frequently, these notes are redeemed with funds obtained
  from the Federal Housing Administration.
 
    Bank Notes are notes issued by local government bodies and agencies as
  those described above to commercial banks as evidence of borrowings. The
  purposes for which the notes are issued are varied but they are frequently
  issued to meet short-term working capital or capital-project needs. These
  notes may have risks similar to the risks associated with TANs and RANs.
 
    Tax-Exempt Commercial Paper (Municipal Paper) represents very short-term
  unsecured, negotiable promissory notes, issued by states, municipalities
  and their agencies. Payment of principal and interest on issues of
  municipal paper may be made from various sources, to the extent the funds
  are available therefrom. Maturities of municipal paper generally will be
  shorter than the maturities of TANs, BANs or RANs. There is a limited
  secondary market for issues of municipal paper.
 
  Certain Municipal Obligations may carry variable or floating rates of
interest whereby the rate of interest is not fixed, but varies with changes in
specified market rates or indices, such as a bank prime rate or a tax-exempt
money market index.
 
                                      S-10
<PAGE>
 
  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 Funds may invest in such other types of notes to the
extent permitted under their investment objective, policies and limitations.
Such notes may be issued for different purposes and may be secured differently
from those mentioned above.
 
  The Funds may also invest in the following taxable temporary investments:
 
    U.S. Government Direct Obligations are issued by the United States
  Treasury and include bills, notes and bonds.
 
    --Treasury bills are issued with maturities of up to one year. They are
     issued in bearer form, are sold on a discount basis and are payable at
     par value at maturity.
 
    --Treasury notes are longer-term interest bearing obligations with
     original maturities of one to seven years.
 
    --Treasury bonds are longer-term interest-bearing obligations with
     original maturities from five to thirty years.
 
  U.S. Government Agencies Securities--Certain federal agencies have been
established as instrumentalities of the United States Government to supervise
and finance certain types of activities. These agencies include, but are not
limited to, the Bank for Cooperatives, Federal Land Banks, Federal Intermediate
Credit Banks, Federal Home Loan Banks, Federal National Mortgage Association,
Government National Mortgage Association, Export-Import Bank of the United
States, and Tennessee Valley Authority. Issues of these agencies, while not
direct obligations of the United States Government, are either backed by the
full faith and credit of the United States or are guaranteed by the Treasury or
supported by the issuing agencies' right to borrow from the Treasury. There can
be no assurance that the United States Government itself will pay interest and
principal on securities as to which it is not legally so obligated.
 
  Certificates of Deposit (CDs)--A certificate of deposit is a negotiable
interest bearing instrument with a specific maturity. CDs are issued by banks
in exchange for the deposit of funds and normally can be traded in the
secondary market, prior to maturity. The Funds will only invest in U.S. dollar
denominated CDs issued by U.S. banks with assets of $1 billion or more.
 
  Commercial Paper--Commercial paper is the term used to designate unsecured
short-term promissory notes issued by corporations. Maturities on these issues
vary from a few days to nine months. Commercial paper may be purchased from
U.S. corporations.
 
  Other Corporate Obligations--The Funds may purchase notes, bonds and
debentures issued by corporations if at the time of purchase there is less than
one year remaining until maturity or if they carry a variable or floating rate
of interest.
 
  Repurchase Agreements--A repurchase agreement is a contractual agreement
whereby the seller of securities (U.S. Government or Municipal Obligations)
agrees to repurchase the same security at a specified price on a future date
agreed upon by the parties. The agreed upon repurchase price determines the
yield during a Fund's holding period. Repurchase agreements are considered to
be loans collateralized by the underlying security that is the subject of the
repurchase contract. The Funds will only enter into repurchase agreements with
dealers, domestic banks or recognized financial institutions that in the
opinion of Nuveen Advisory present minimal credit risk. The risk to the Funds
is limited to the ability of the issuer to pay the agreed-upon repurchase price
on the delivery date; however, although the value of the underlying collateral
at the time the transaction is entered into always equals or exceeds the
agreed-upon repurchase price, if the value of the collateral declines there is
a risk of loss of both principal and interest. In the event of default, the
collateral may be sold but a Fund
 
                                      S-11
<PAGE>
 
might incur a loss if the value of the collateral declines, and might incur
disposition costs or experience delays in connection with liquidating the
collateral. In addition, if bankruptcy proceedings are commenced with respect
to the seller of the security, realization upon the collateral by a Fund may be
delayed or limited. Nuveen Advisory will monitor the value of collateral at the
time the transaction is entered into and at all times subsequent during the
term of the repurchase agreement in an effort to determine that the value
always equals or exceeds the agreed upon price. In the event the value of the
collateral declined below the repurchase price, Nuveen Advisory will demand
additional collateral from the issuer to increase the value of the collateral
to at least that of the repurchase price. Each of the Funds will not invest
more than 10% of its assets in repurchase agreements maturing in more than
seven days.

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

  Nuveen Advisory has agreed to waive all or a portion of its management fee or
reimburse certain expenses of the Ohio Fund in order to prevent total operating
expenses (including 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 average daily net
asset value of any class of shares of the Fund.
 
  For all of the Funds, Nuveen Advisory has committed through at least 1998 to
continue Flagship's general dividend-setting practices.

  In addition to the management fee of Nuveen Advisory, each Fund pays all
other costs and expenses of its operations and a portion of the Trust's general
administrative expenses allocated in proportion to the net assets of each Fund.
 
  Nuveen Advisory is a wholly owned subsidiary of John Nuveen & Co.
Incorporated ("Nuveen"), the Funds' principal underwriter. Nuveen is the
sponsor of the Nuveen Defined Portfolios, and is the principal underwriter for
the Nuveen Mutual Funds, and has served as co-managing underwriter for the
shares of the Nuveen Exchange-Traded Funds. Over 1,300,000 individuals have
invested to date in Nuveen's funds and Defined Portfolios. Founded in 1898,
Nuveen is a subsidiary of The John Nuveen Company which, in turn, is
approximately 78% owned by The St. Paul Companies, Inc. ("St. Paul"). St. Paul
is located in St. Paul, Minnesota and is principally engaged in providing
property-liability insurance through subsidiaries. Effective January 1, 1997,
The John Nuveen Company acquired Flagship Resources Inc., and as part of that
acquisition, Flagship Financial, the adviser to the Flagship Funds, was merged
with Nuveen Advisory.
 
  The Funds, the other Nuveen funds, Nuveen Advisory, and other related
entities have adopted a code of ethics which essentially prohibits all Nuveen
fund management personnel, including Nuveen fund portfolio managers, from
engaging in personal investments which compete or interfere with, or attempt to
take advantage of, a Fund's anticipated or actual portfolio transactions, and
is designed to assure that the interests of Fund shareholders are placed before
the interests of Nuveen personnel in connection with personal investment
transactions.
 
PORTFOLIO TRANSACTIONS
 
  Nuveen Advisory, in effecting purchases and sales of portfolio securities for
the account of each Fund, will place orders in such manner as, in the opinion
of management, will offer the best price and market for the execution of each
transaction. Portfolio securities will normally be purchased directly from an
underwriter or in the over-the-counter market from the principal dealers in
such securities, unless it appears that a better price or execution may be
obtained elsewhere. Portfolio securities will not be purchased from Nuveen or
its affiliates except in compliance with the Investment Company Act of 1940.
 
 
                                      S-25
<PAGE>
 
  The Funds expect that all portfolio transactions will be effected on a
principal (as opposed to an agency) basis and, accordingly, do not expect to
pay any brokerage commissions. Purchases from underwriters will include a
commission or concession paid by the issuer to the underwriter, and purchases
from dealers will include the spread between the bid and asked price. Given the
best price and execution obtainable, it will be the practice of the Funds to
select dealers which, in addition, furnish research information (primarily
credit analyses of issuers and general economic reports) and statistical and
other services to Nuveen Advisory. It is not possible to place a dollar value
on information and statistical and other services received from dealers. Since
it is only supplementary to Nuveen Advisory's own research efforts, the receipt
of research information is not expected to reduce significantly Nuveen
Advisory's expenses. While Nuveen Advisory will be primarily responsible for
the placement of the business of the Funds, the policies and practices of
Nuveen Advisory in this regard must be consistent with the foregoing and will,
at all times, be subject to review by the Board of Trustees.
 
  Nuveen Advisory reserves the right to, and does, manage other investment
accounts and investment companies for other clients, which may have investment
objectives similar to the Funds. Subject to applicable laws and regulations,
Nuveen Advisory will attempt to allocate equitably portfolio transactions among
the Funds and the portfolios of its other clients purchasing or selling
securities whenever decisions are made to purchase or sell securities by a Fund
and one or more of such other clients simultaneously. In making such
allocations the main factors to be considered will be the respective investment
objectives of the Fund and such other clients, the relative size of portfolio
holdings of the same or comparable securities, the availability of cash for
investment by the Fund and such other clients, the size of investment
commitments generally held by the Fund and such other clients and opinions of
the persons responsible for recommending investments to the Fund and such other
clients. While this procedure could have a detrimental effect on the price or
amount of the securities available to a Fund from time to time, it is the
opinion of the Board of Trustees that the benefits available from Nuveen
Advisory's organization will outweigh any disadvantage that may arise from
exposure to simultaneous transactions.
 
  Under the Investment Company Act of 1940, the Funds may not purchase
portfolio securities from any underwriting syndicate of which Nuveen is a
member except under certain limited conditions set forth in Rule 10f-3. The
Rule sets forth requirements relating to, among other things, the terms of an
issue of Municipal Obligations purchased by a Fund, the amount of Municipal
Obligations which may be purchased in any one issue and the assets of a Fund
which may be invested in a particular issue. In addition, purchases of
securities made pursuant to the terms of the Rule must be approved at least
quarterly by the Board of Trustees, including a majority of the trustees who
are not interested persons of the Trust.
 
NET ASSET VALUE
 
  As stated in the Prospectus, the net asset value of the shares of the Funds
will be determined separately for each class of the Funds' shares by The Chase
Manhattan Bank, the Funds' custodian, as of the close of trading (normally 4:00
p.m. Eastern Time) on each day on which the Exchange is normally open for
trading. The Exchange is not open for trading on New Year's Day, Washington's
Birthday, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving
Day and Christmas Day. The net asset value per share of a class of shares of a
Fund will be computed by dividing the value of the Fund's assets attributable
to the class, less the liabilities attributable to the class, by the number of
shares of the class outstanding.
 
  In determining net asset value for the Funds, the Funds' custodian utilizes
the valuations of portfolio securities furnished by a pricing service approved
by the trustees. Securities for which quotations are not readily available
(which constitute a majority of the securities held by the Funds) are valued at
fair value as determined by the pricing service using methods which include
consideration of the following: yields or prices of municipal
 
                                      S-26
<PAGE>
 
bonds of comparable quality, type of issue, coupon, maturity and rating;
indications as to value from dealers; and general market conditions. The
pricing service may employ electronic data processing techniques and/or a
matrix system to determine valuations. The procedures of the pricing service
and its valuations are reviewed by the officers of the Trust under the general
supervision of the Board of Trustees.
 
TAX MATTERS
 
FEDERAL INCOME TAX MATTERS
 
  The following discussion of federal income tax matters is based upon the
advice of Morgan, Lewis & Bockius LLP, counsel to the Trust.
 
  Each Fund intends to qualify under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code") for tax treatment as a regulated investment
company. In order to qualify as a regulated investment company, a Fund must
satisfy certain requirements relating to the source of its income,
diversification of its assets, and distributions of its income to shareholders.
First, a Fund must derive at least 90% of its annual gross income (including
tax-exempt interest) from dividends, interest, payments with respect to
securities loans, gains from the sale or other disposition of stock or
securities, foreign currencies or other income (including but not limited to
gains from options and futures) derived with respect to its business of
investing in such stock or securities (the "90% gross income test"). Second,
for taxable years beginning on or before August 5, 1997, a Fund must derive
less than 30% of its annual gross income from the sale or other disposition of
any of the following which was held for less than three months: (i) stock or
securities and (ii) certain options, futures, or forward contracts (the "short-
short test"). The short-short test will not be a requirement for qualification
as a regulated investment company for taxable years beginning after August 5,
1997. Third, a Fund must diversify its holdings so that, at the close of each
quarter of its taxable year, (i) at least 50% of the value of its total assets
is comprised of cash, cash items, United States Government securities,
securities of other regulated investment companies and other securities limited
in respect of any one issuer to an amount not greater in value than 5% of the
value of a Fund's total assets and to not more than 10% of the outstanding
voting securities of such issuer, and (ii) not more than 25% of the value of
the total assets is invested in the securities of any one issuer (other than
United States Government securities and securities of other regulated
investment companies) or two or more issuers controlled by a Fund and engaged
in the same, similar or related trades or businesses.
 
  As a regulated investment company, a Fund will not be subject to federal
income tax in any taxable year for which it distributes at least 90% of the sum
of (i) its "investment company taxable income" (which includes dividends,
taxable interest, taxable original issue discount and market discount income,
income from securities lending, net short-term capital gain in excess of long-
term capital loss, and any other taxable income other than "net capital gain"
(as defined below) and is reduced by deductible expenses) and (ii) its net tax-
exempt interest (the excess of its gross tax-exempt interest income over
certain disallowed deductions). A Fund may retain for investment its net
capital gain (which consists of the excess of its net long-term capital gain
over its short-term capital loss). However, if a Fund retains any net capital
gain or any investment company taxable income, it will be subject to tax at
regular corporate rates on the amount retained. If a Fund retains any capital
gain, such Fund may designate the retained amount as undistributed capital
gains in a notice to its shareholders who, if subject to federal income tax on
long-term capital gains, (i) will be required to include in income for federal
income tax purposes, as long-term capital gain, their shares of such
undistributed amount, and (ii) will be entitled to credit their proportionate
shares of the tax paid by such Fund against their federal income tax
liabilities if any, and to claim refunds to the extent the credit exceeds such
liabilities. For federal income tax purposes, the tax basis of shares owned by
a shareholder of the Fund will be increased by an amount equal under current
law to 65% of the amount of undistributed capital gains included in the
shareholder's gross income. Each Fund intends to distribute at least annually
to its shareholders all or substantially all of its net tax-exempt interest and
any investment company taxable income and net capital gain.
 
                                      S-27
<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.
 
  Each Fund also intends to satisfy conditions (including requirements as to
the proportion of its assets invested in Municipal Obligations) that will
enable it to designate distributions from the interest income generated by
investments in Municipal Obligations, which is exempt from regular federal
income tax when received by such Fund, as exempt-interest dividends.
Shareholders receiving exempt-interest dividends will not be subject to regular
federal income tax on the amount of such dividends. Insurance proceeds received
by a Fund under any insurance policies in respect of scheduled interest
payments on defaulted Municipal Obligations will be excludable from federal
gross income under Section 103(a) of the Code. In the case of non-appropriation
by a political subdivision, however, there can be no assurance that payments
made by the insurer representing interest on "non-appropriation" lease
obligations will be excludable from gross income for federal income tax
purposes. See "Investment Policies and Investment Portfolio; Portfolio
Securities."
 
  Distributions by a Fund of net interest received from certain taxable
temporary investments (such as certificates of deposit, commercial paper and
obligations of the U.S. Government, its agencies and instrumentalities) and net
short-term capital gains realized by a Fund, if any, will be taxable to
shareholders as ordinary income whether received in cash or additional shares.
If a Fund purchases a Municipal Obligation at a market discount, any gain
realized by the Fund upon sale or redemption of the Municipal Obligation will
be treated as taxable interest income to the extent such gain does not exceed
the market discount, and any gain realized in excess of the market discount
will be treated as capital gains. Any net long-term capital gains realized by a
Fund and distributed to shareholders in cash or additional shares, will be
taxable to shareholders as long-term capital gains regardless of the length of
time investors have owned shares of a Fund. Distributions by a Fund that do not
constitute ordinary income dividends, exempt-interest dividends, or capital
gain dividends will be treated as a return of capital to the extent of (and in
reduction of) the shareholder's tax basis in his or her shares. Any excess will
be treated as gain from the sale of his or her shares, as discussed below.
 
  If a Fund has both tax-exempt and taxable income, it will use the "average
annual" method for determining the designated percentage that is taxable income
and designate the use of such method within 60 days after the end of the Fund's
taxable year. Under this method, one designated percentage is applied uniformly
to all distributions made during the Fund's taxable year. The percentage of
income designated as tax-exempt for any particular distribution may be
substantially different from the percentage of the Fund's income that was tax-
exempt during the period covered by the distribution.
 
  If a Fund engages in hedging transactions involving financial futures and
options, these transactions will be subject to special tax rules, the effect of
which may be to accelerate income to a Fund, defer a Fund's losses, cause
adjustments in the holding periods of a Fund's securities, convert long-term
capital gains into short-term capital gains and convert short-term capital
losses into long-term capital losses. These rules could therefore affect the
amount, timing and character of distributions to shareholders.
 
  Because the taxable portion of a Fund's investment income consists primarily
of interest, none of its dividends, whether or not treated as exempt-interest
dividends, is expected to qualify under the Internal Revenue Code for the
dividends received deductions for corporations.
 
  Prior to purchasing shares in a Fund, the impact of dividends or
distributions which are expected to be or have been declared, but not paid,
should be carefully considered. Any dividend or distribution declared shortly
 
                                      S-28
<PAGE>
 
after a purchase of such shares prior to the record date will have the effect
of reducing the per share net asset value by the per share amount of the
dividend or distribution.
 
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to shareholders of
record on a specified date in one of those months and paid during the following
January, will be treated as having been distributed by a Fund (and received by
the shareholders) on December 31.
 
  The redemption or exchange of the shares of a Fund normally will result in
capital gain or loss to the shareholders. Present law taxes both long- and
short-term capital gains of corporations at the rates applicable to ordinary
income. For non-corporate taxpayers, however, (i) gain on the sale of shares
held for more than 18 months will generally be taxed at a maximum marginal rate
of 20%, (ii) gain on the sale of shares held for more than one year but not
more than 18 months will generally be taxed at a maximum marginal rate of 28%,
and (iii) gain on the sale of shares held for not more than one year and other
ordinary income will generally be taxed at a maximum marginal rate of 39.6%.
Because of the limitations on itemized deductions and the deduction for
personal exemptions applicable to higher income taxpayers, the effective tax
rate on net income may be higher in certain circumstances.
 
  All or a portion of a sales charge paid in purchasing shares of a Fund cannot
be taken into account for purposes of determining gain or loss on the
redemption or exchange of such shares within 90 days after their purchase to
the extent shares of a Fund or another fund are subsequently acquired without
payment of a sales charge pursuant to the reinvestment or exchange privilege.
Any disregarded portion of such charge will result in an increase in the
shareholder's tax basis in the shares subsequently acquired. Moreover, losses
recognized by a shareholder on the redemption or exchange of shares of a Fund
held for six months or less are disallowed to the extent of any distribution of
exempt-interest dividends received with respect to such shares and, if not
disallowed, such losses are treated as long-term capital losses to the extent
of any distributions of long-term capital gains made with respect to such
shares. In addition, no loss will be allowed on the redemption or exchange of
shares of a Fund if the shareholder purchases other shares of such Fund
(whether through reinvestment of distributions or otherwise) or the shareholder
acquires or enters into a contract or option to acquire securities that are
substantially identical to shares of a Fund within a period of 61 days
beginning 30 days before and ending 30 days after such redemption or exchange.
If disallowed, the loss will be reflected in an adjustment to the basis of the
shares acquired.
 
  It may not be advantageous from a tax perspective for shareholders to redeem
or exchange shares after tax-exempt income has accrued but before the record
date for the exempt-interest dividend representing the distribution of such
income. Because such accrued tax-exempt income is included in the net asset
value per share (which equals the redemption or exchange value), such a
redemption could result in treatment of the portion of the sales or redemption
proceeds equal to the accrued tax-exempt interest as taxable gain (to the
extent the redemption or exchange price exceeds the shareholder's tax basis in
the shares disposed of) rather than tax-exempt interest.
 
  In order to avoid a 4% federal excise tax, a Fund must distribute or be
deemed to have distributed by December 31 of each calendar year at least 98% of
its taxable ordinary income for such year, at least 98% of the excess of its
realized capital gains over its realized capital losses (generally computed on
the basis of the one-year period ending on October 31 of such year) and 100% of
any taxable ordinary income and the excess of realized capital gains over
realized capital losses for the prior year that was not distributed during such
year and on which such Fund paid no federal income tax. For purposes of the
excise tax, a regulated investment company may reduce its capital gain net
income (but not below its net capital gain) by the amount of any net ordinary
loss for the calendar year. The Funds intend to make timely distributions in
compliance with these requirements and consequently it is anticipated that they
generally will not be required to pay the excise tax.

  If in any year a Fund should fail to qualify under Subchapter M for tax
treatment as a regulated investment company, the Fund would incur a regular
corporate federal income tax upon its income for that year (other than interest
income from Municipal Obligations), and distributions to its shareholders would
be taxable to shareholders as ordinary dividend income for federal income tax
purposes to the extent of the Fund's available earnings and profits.
 
  Because the Funds may invest in private activity bonds, the interest on which
is not federally tax-exempt to persons who are "substantial users" of the
facilities financed by such bonds or "related persons" of such "substantial
users," the Funds may not be an appropriate investment for shareholders who are
considered either a "substantial user" or a "related person" within the meaning
of the Code. For additional information, investors should consult their tax
advisers before investing in a Fund.
 
  Federal tax law imposes an alternative minimum tax with respect to both
corporations and individuals. Interest on certain Municipal Obligations, such
as bonds issued to make loans for housing purposes or to private entities (but
not for certain tax-exempt organizations such as universities and non-profit
hospitals), is included as an item of tax preference in determining the amount
of a taxpayer's alternative minimum taxable income. To the extent that a Fund
receives income from Municipal Obligations subject to the alternative minimum
tax, a portion of the dividends paid by it, although otherwise exempt from
federal income tax, will be taxable to shareholders to the extent that their
tax liability is determined under the alternative minimum tax regime. The Funds
will annually supply shareholders with a report indicating the percentage of
Fund income attributable to Municipal Obligations subject to the federal
alternative minimum tax.
 
  In addition, the alternative minimum taxable income for corporations is
increased by 75% of the difference between an alternative measure of income
("adjusted current earnings") and the amount otherwise determined to be the
alternative minimum taxable income. Interest on all Municipal Obligations, and
therefore all distributions by the Funds that would otherwise be tax-exempt, is
included in calculating a corporation's adjusted current earnings.
 
  Tax-exempt income, including exempt-interest dividends paid by a Fund, will
be added to the taxable income of individuals receiving social security or
railroad retirement benefits in determining whether a portion of that benefit
will be subject to federal income tax.
 
  The Code provides that interest on indebtedness incurred or continued to
purchase or carry shares of any Fund is not deductible. Under rules used by the
IRS for determining when borrowed funds are considered used for the purpose of
purchasing or carrying particular assets, the purchase of shares of a Fund may
be considered to have been made with borrowed funds even though such funds are
not directly traceable to the purchase of shares.
 
  The Funds are required in certain circumstances to withhold 31% of taxable
dividends and certain other payments paid to non-corporate holders of shares
who have not furnished to the Funds their correct taxpayer identification
number (in the case of individuals, their social security number) and certain
certifications, or who are otherwise subject to backup withholding.
 
  The foregoing is a general and abbreviated summary of the provisions of the
Code and Treasury Regulations presently in effect as they directly govern the
taxation of the Fund and its shareholders. For complete provisions, reference
should be made to the pertinent Code sections and Treasury Regulations. The
Code and Treasury Regulations are subject to change by legislative or
administrative action, and any such change may be retroactive with respect to
Fund transactions. Shareholders are advised to consult their own tax advisers
for more detailed information concerning the federal taxation of the Funds and
the income tax consequences to their shareholders.

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

Kansas corporate income tax only if it has a sufficient nexus with Kansas. If
it is subject to such taxes, it does not expect to pay a material amount of
either tax.
 
  Distributions by the Kansas Fund that are attributable to interest on any
obligation of Kansas and its political subdivisions issued after December 31,
1987, and interest on certain such obligations issued before January 1, 1988,
or to interest on obligations of the United States, its territories,
possessions or instrumentalities that are exempt from state taxation under
federal law will not be subject to the Kansas personal income tax or the Kansas
corporate income tax. All other distributions, including distributions
attributable to capital gains, will be subject to the Kansas personal and
corporate income taxes.

PERFORMANCE INFORMATION
 
  The historical investment performance of the Funds may be shown in the form
of "yield," "taxable equivalent yield," "average annual total return,"
"cumulative total return" and "taxable equivalent total return" figures, each
of which will be calculated separately for each class of shares.
 
  In accordance with a standardized method prescribed by rules of the
Securities and Exchange Commission ("SEC"), yield is computed by dividing the
net investment income per share earned during the specified one month or 30-day
period by the maximum offering price per share on the last day of the period,
according to the following formula:
 
 
                            Yield=2[(a-b +1)/6/ -1]
                                     cd
 
  In the above formula, a = dividends and interest earned during the period; b
= expenses accrued for the period (net of reimbursements); c = the average
daily number of shares outstanding during the period that were entitled to
receive dividends; and d = the maximum offering price per share on the last day
of the period. In the case of Class A shares, the maximum offering price
includes the current maximum front-end sales charge of 4.20% (2.5% for the
Kentucky Limited Term Fund).
 
  In computing yield, the Funds follow certain standardized accounting
practices specified by SEC rules. These practices are not necessarily
consistent with those that the Funds use to prepare their annual and interim
 
                                      S-35
<PAGE>
 
financial statements in conformity with generally accepted accounting
principles. Thus, yield may not equal the income paid to shareholders or the
income reported in a Fund's financial statements.
 
  Taxable equivalent yield is computed by dividing that portion of the yield
which is tax-exempt by the remainder of (1 minus the stated combined federal
and state income tax rate, taking into account the deductibility of state taxes
for federal income tax purposes) and adding the product to that portion, if
any, of the yield that is not tax exempt.
 
  The taxable equivalent yields quoted below are based upon (1) the stated
combined federal and state income tax rates and (2) the yields for the 30-day
period quoted in the left-hand column.

   * The combined tax rates used in these tables represent the highest or one
     of the highest combined tax rates applicable to state taxpayers, rounded
     to the nearest .5%; these rates do not reflect the current federal tax
     limitations on itemized deductions and personal exemptions, which may
     raise the effective tax rate and taxable equivalent yield for taxpayers
     above certain income levels.
 
  For additional information concerning taxable equivalent yields, see the
Taxable Equivalent Yields table in the Prospectus.
 
  The Funds may from time to time in their advertising and sales materials
report a quotation of their current distribution rate. The distribution rate
represents a measure of dividends distributed for a specified period.
Distribution rate is computed by taking the most recent monthly tax-free income
dividend per share, multiplying it by 12 to annualize it, and dividing by the
appropriate price per share (e.g., net asset value for purchases to be made
without a load such as reinvestments from Nuveen Defined Portfolios, or the
maximum public offering price). The distribution rate differs from yield and
total return and therefore is not intended to be a complete measure of
performance. Distribution rate may sometimes differ from yield because a Fund
may be paying out more than it is earning and because it may not include the
effect of amortization of bond premiums to the extent such premiums arise after
the bonds were purchased.
 
  The distribution rates as of the period quoted, based on the maximum public
offering price then in effect for the Funds, and assuming the imposition of the
maximum sales charge for Class A Shares of 4.20% (2.5% for the Kentucky Limited
Term Municipal Bond Fund), were as follows:

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

  Calculation of cumulative total return is not subject to a prescribed
formula. Cumulative total return for a specific period is calculated by first
taking a hypothetical initial investment in Fund shares on the first day of the
period, deducting (in some cases) the maximum sales charge, and computing the
"redeemable value" of that investment at the end of the period. The cumulative
total return percentage is then determined by subtracting the initial
investment from the redeemable value and dividing the remainder by the initial
investment and expressing the result as a percentage. The calculation assumes
that all income and capital gains distributions by the Fund have been
reinvested at net asset value on the reinvestment dates during the period.
Cumulative total return may also be shown as the increased dollar value of the
hypothetical investment over the period. Cumulative total return calculations
that do not include the effect of the sales charge would be reduced if such
charge were included.
 
  The cumulative total return figures for the Funds, including the effect of
the maximum sales charge for the Class A Shares, and applicable CDSC for Class
B Shares, for the one-year, five-year, and ten-year periods (as applicable)
ended May 31, 1998, and for the period since inception through May 31, 1998,

  Calculation of taxable equivalent total return is also not subject to a
prescribed formula. Taxable equivalent total return for a specific period is
calculated by first taking a hypothetical initial investment in Fund shares on
the first day of the period, computing the total return for each calendar year
in the period in the manner described above, and increasing the total return
for each such calendar year by the amount of additional income that a taxable
fund would need to have generated to equal the income on an after-tax basis, at
a specified income tax rate (usually the highest marginal federal tax rate),
calculated as described above under the discussion of "taxable equivalent
yield." The resulting amount for the calendar year is then divided by the
initial investment amount to arrive at a "taxable equivalent total return
factor" for the calendar year. The taxable equivalent total return factors for
all the calendar years are then multiplied together and the result is then
annualized by taking its Nth root (N representing the number of years in the
period) and subtracting 1, which provides a taxable equivalent total return
expressed as a percentage.
 
  Using the 44.3% maximum marginal federal tax rate for 1998, the annual
taxable equivalent total return for the Kansas Municipal Bond Fund, Class A
Shares, for the one-year period ended May 31, 1998 was 13.49%.
 
  Class A Shares of the Funds are sold at net asset value plus a current
maximum sales charge of 4.20% of the offering price. This current maximum sales
charge will typically be used for purposes of calculating performance figures.
Yield, returns and net asset value of each class of shares of the Funds will
fluctuate. Factors affecting the performance of the Funds include general
market conditions, operating expenses and investment management. Any additional
fees charged by a securities representative or other financial services firm
would reduce returns described in this section. Shares of the Funds are
redeemable at net asset value, which may be more or less than original cost.
 
  In reports or other communications to shareholders or in advertising and
sales literature, the Funds may also compare their performance with that of:
(1) the Consumer Price Index or various unmanaged bond indexes such as the
Lehman Brothers Municipal Bond Index and the Salomon Brothers High Grade
Corporate Bond Index and (2) other fixed income or municipal bond mutual funds
or mutual fund indexes as reported by Lipper Analytical Services, Inc.
("Lipper"), Morningstar, Inc. ("Morningstar"), Wiesenberger Investment
Companies Service ("Wiesenberger") and CDA Investment Technologies, Inc.
("CDA") or similar independent services which monitor the performance of mutual
funds, or other industry or financial publications such as Barron's, Changing
Times, Forbes and Money Magazine. Performance comparisons by these indexes,
services or publications may rank mutual funds over different periods of time
by means of aggregate, average, year-by-year, or other types of total return
and performance figures. Any given performance quotation or performance
comparison should not be considered as representative of the performance of the
Funds for any future period.

  Each Fund may from time to time in its advertising and sales materials
compare its current yield or total return with the yield or total return on
taxable investments such as corporate or U.S. Government bonds, bank
certificates of deposit (CDs) or money market funds. These taxable investments
have investment characteristics that differ from those of the Funds. U.S.
Government bonds, for example, are long-term investments backed by the full
faith and credit of the U.S. Government, and bank CDs are generally short-term,
FDIC-insured investments, which pay fixed principal and interest but are
subject to fluctuating rollover rates. Money market funds are short-term
investments with stable net asset values, fluctuating yields and special
features enhancing liquidity.
 
  There are differences and similarities between the investments which the
Funds may purchase and the investments measured by the indexes and reporting
services which are described herein. The Consumer Price Index is generally
considered to be a measure of inflation. The CDA Mutual Fund-Municipal Bond
Index is a weighted performance average of other mutual funds with a federally
tax-exempt income objective. The Salomon Brothers High Grade Corporate Bond
Index is an unmanaged index that generally represents the performance of high
grade long-term taxable bonds during various market conditions. The Lehman
Brothers Municipal Bond Index is an unmanaged index that generally represents
the performance of high grade intermediate and long-term municipal bonds during
various market conditions. Lipper calculates municipal bond fund averages based
on average maturity and credit quality. Morningstar rates mutual funds by
overall risk-adjusted performance, investment objectives, and assets. Lipper,
Morningstar, Wiesenberger and CDA are widely recognized mutual fund reporting
services whose performance calculations are based upon changes in net asset
value with all dividends reinvested and which do not include the effect of any
sales charges. The market prices and yields of taxable and tax-exempt bonds
will fluctuate. The Funds primarily invest in investment grade Municipal
Obligations in pursuing their objective of as high a level of current interest
income which is exempt from federal and state income tax as is consistent, in
the view of the Funds' management, with preservation of capital.
 
  The Funds may also compare their taxable equivalent total return performance
to the total return performance of taxable income funds such as treasury
securities funds, corporate bond funds (either investment grade or high yield),
or Ginnie Mae funds. These types of funds, because of the character of their
underlying securities, differ from municipal bond funds in several respects.
The susceptibility of the price of treasury bonds to credit risk is far less
than that of municipal bonds, but the price of treasury bonds tends to be
slightly more susceptible to change resulting from changes in market interest
rates. The susceptibility of the price of investment grade corporate bonds and
municipal bonds to market interest rate changes and general credit changes is
similar. High yield bonds are subject to a greater degree of price volatility
than municipal bonds resulting from changes in market interest rates and are
particularly susceptible to volatility from credit changes. Ginnie Mae bonds
are generally subject to less price volatility than municipal bonds from credit
concerns, due primarily to the fact that the timely payment of monthly
installments of principal and interest are backed by the full faith and credit
of the U.S. Government, but Ginnie Mae bonds of equivalent coupon and maturity
are generally more susceptible to price volatility resulting from market
interest rate changes. In addition, the volatility of Ginnie Mae bonds due to
changes in market interest rates may differ from municipal bonds of comparable
coupon and maturity because bonds of the sensitivity of Ginnie Mae prepayment
experience to change in interest rates.

ADDITIONAL INFORMATION ON THE PURCHASE AND REDEMPTION OF FUND SHARES
 
  As described in the Prospectus, the Funds provide you with alternative ways
of purchasing Fund shares based upon your individual investment needs and
preferences.
 
  Each class of shares of a Fund represents an interest in the same portfolio
of investments. Each class of shares is identical in all respects except that
each class bears its own class expenses, including distribution and
administration expenses, and each class has exclusive voting rights with
respect to any distribution or service plan applicable to its shares. As a
result of the differences in the expenses borne by each class of shares, net
income per share, dividends per share and net asset value per share will vary
among a Fund's classes of shares.
 
  Shareholders of each class will share expenses proportionately for services
that are received equally by all shareholders. A particular class of shares
will bear only those expenses that are directly attributable to that class,
where the type or amount of services received by a class varies from one class
to another. For example, class-specific expenses generally will include
distribution and service fees.
 
  The minimum initial investment is $3,000 per fund share class, and may be
lower for accounts opened through fee-based programs for which the program
sponsor has established a single master account with the fund's transfer agent
and performs all sub-accounting services related to that account.
 
  Class A Shares may be purchased at a public offering price equal to the
applicable net asset value per share plus an up-front sales charge imposed at
the time of purchase as set forth in the Prospectus. Shareholders may qualify
for a reduced sales charge, or the sales charge may be waived in its entirety,
as described below. Class A Shares are also subject to an annual service fee of
 .20%. See "Distribution and Service Plans." Set forth below is an example of
the method of computing the offering price of the Class A shares of a Fund. The
example assumes a purchase on May 31, 1998 of Class A shares from the Nuveen
Flagship Kansas Municipal Bond 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.

(1) You can buy $1 million or more of Class A shares at net asset value
    without an up-front sales charge. Nuveen pays authorized dealers of record
    on these share purchases a sales commission of 1.00% (0.50% for the
    Kentucky Limited Term fund) of the first $2.5 million, plus .50% of the
    next $2.5 million, plus .25% of the amount over $5.0 million. If you
    redeem your shares within 18 months of purchase, you may have to pay a
    CDSC of 1% (0.50% for the Kentucky Limited Term fund) of either your
    purchase price or your redemption proceeds, whichever is lower. You do not
    have to pay this CDSC if your financial adviser has made arrangements with
    Nuveen and agrees to waive the commission.
 
REDUCTION OR ELIMINATION OF UP-FRONT SALES CHARGE ON CLASS A SHARES AND CLASS
R SHARE PURCHASE AVAILABILITY
 
  Rights of Accumulation. You may qualify for a reduced sales charge on a
purchase of Class A Shares of any Fund if the amount of your purchase, when
added to the value that day of all of your prior purchases of shares of any
Fund or of another Nuveen Mutual Fund, or Nuveen exchange-traded fund, or
units of a Nuveen Defined Portfolio, on which an up-front sales charge or
ongoing distribution fee is imposed or is normally imposed, falls within the
amounts stated in the Class A Sales Charges and Commissions table in "How You
Can Buy and Sell Shares" in the Prospectus. You or your financial adviser must
notify Nuveen or the Fund's transfer agent of any cumulative discount whenever
you plan to purchase Class A Shares of a Fund that you wish to qualify for a
reduced sales charge.
 
  Letter of Intent. You may qualify for a reduced sales charge on a purchase
of Class A Shares of any Fund if you plan to purchase Class A Shares of Nuveen
Mutual Funds over the next 13 months and the total amount of your purchases
would, if purchased at one time, qualify you for one of the reduced sales
charges shown in the Class A Sales Charges and Commissions table in "How You
Can Buy and Sell Shares" in the Prospectus. In order to take advantage of this
option, you must complete the applicable section of the Application Form or
sign and deliver either to an Authorized Dealer or to the Fund's transfer
agent a written Letter of Intent in a form acceptable to Nuveen. A Letter of
Intent states that you intend, but are not obligated, to purchase over the
next 13 months a stated total amount of Class A Shares that would qualify you
for a reduced sales charge shown above. You may count shares of a Nuveen
Mutual Fund that you already own on which you paid an up-front sales charge or
an ongoing distribution fee and any Class B or C Shares of a Nuveen Mutual
Fund that you purchase over the next 13 months towards completion of your
investment program, but you will receive a reduced sales charge only on new
Class A Shares you purchase with a sales charge over the 13 months. You cannot
count towards completion of your investment program Class A Shares that you
purchase without a sales charge through investment of distributions from a
Nuveen Mutual Fund or a Nuveen Defined Portfolio, or otherwise.
 
 
                                     S-44
<PAGE>
 
  By establishing a Letter of Intent, you agree that your first purchase of
Class A Shares of a Fund following execution of the Letter of Intent will be at
least 5% of the total amount of your intended purchases. You further agree that
shares representing 5% of the total amount of your intended purchases will be
held in escrow pending completion of these purchases. All dividends and capital
gains distributions on Class A Shares held in escrow will be credited to your
account. If total purchases, less redemptions, prior to the expiration of the
13 month period equal or exceed the amount specified in your Letter of Intent,
the Class A Shares held in escrow will be transferred to your account. If the
total purchases, less redemptions, exceed the amount specified in your Letter
of Intent and thereby qualify for a lower sales charge than the sales charge
specified in your Letter of Intent, you will receive this lower sales charge
retroactively, and the difference between it and the higher sales charge paid
will be used to purchase additional Class A Shares on your behalf. If the total
purchases, less redemptions, are less than the amount specified, you must pay
Nuveen an amount equal to the difference between the amounts paid for these
purchases and the amounts which would have been paid if the higher sales charge
had been applied. If you do not pay the additional amount within 20 days after
written request by Nuveen or your financial adviser, Nuveen will redeem an
appropriate number of your escrowed Class A Shares to meet the required
payment. By establishing a Letter of Intent, you irrevocably appoint Nuveen as
attorney to give instructions to redeem any or all of your escrowed shares,
with full power of substitution in the premises.
 
  You or your financial adviser must notify Nuveen or the Fund's transfer agent
whenever you make a purchase of Fund shares that you wish to be covered under
the Letter of Intent option.
 
  Reinvestment of Nuveen Defined Portfolio Distributions. You may purchase
Class A Shares without an up-front sales charge by reinvestment of
distributions from any of the various Defined Portfolios sponsored by Nuveen.
There is no initial or subsequent minimum investment requirement for such
reinvestment purchases.
 
  Group Purchase Programs. If you are a member of a qualified group, you may
purchase Class A Shares of any Fund or of another Nuveen Mutual Fund at the
reduced sales charge applicable to the group's purchases taken as a whole. A
"qualified group" is one which has previously been in existence, has a purpose
other than investment, has ten or more participating members, has agreed to
include Fund sales publications in mailings to members and has agreed to comply
with certain administrative requirements relating to its group purchases.
 
  Under any group purchase program, the minimum initial investment in Class A
shares of any particular Fund or portfolio for each participant in the program
is $3,000 and the minimum monthly investment in Class A shares of any
particular Fund or portfolio by each participant is $50. No certificates will
be issued for any participant's account. All dividends and other distributions
by a Fund will be reinvested in additional Class A Shares of the same Fund. No
participant may utilize a systematic withdrawal program.
 
  To establish a group purchase program, both the group itself and each
participant must fill out special application materials, which the group
administrator may obtain from the group's financial adviser, by calling Nuveen
toll-free (800) 257-8787.
 
  Reinvestment of Redemption Proceeds from Unaffiliated Funds. You may also
purchase Class A Shares at net asset value without a sales charge if the
purchase takes place through a broker-dealer and represents the reinvestment of
the proceeds of the redemption of shares of one or more registered investment
companies not affiliated with Nuveen. You must provide appropriate
documentation that the redemption occurred not more than one year prior to the
reinvestment of the proceeds in Class A Shares, and that you either paid an up-
front sales charge or were subject to a contingent deferred sales charge in
respect of the redemption of such shares of such other investment company.

  Special Sales Charge Waivers. Class A Shares of a Fund may be purchased at
net asset value without a sales charge, and may be purchased by the following
categories of investors:
 
  . investors purchasing $1,000,000 or more;
 
  . officers, trustees and former trustees of the Nuveen and Flagship Funds;
 
  . bona fide, full-time and retired employees of Nuveen, any parent company
    of Nuveen, and subsidiaries thereof, or their immediate family members;
 
  . any person who, for at least 90 days, has been an officer, director or
    bona fide employee of any Authorized Dealer, or their immediate family
    members;
 
  . officers and directors of bank holding companies that make Fund shares
    available directly or through subsidiaries or bank affiliates, or their
    immediate family members;
 
  . bank or broker-affiliated trust departments investing funds over which
    they exercise exclusive discretionary investment authority and that are
    held in a fiduciary, agency, advisory, custodial or similar capacity;
 
  . investors purchasing on a periodic fee, asset-based fee or no transaction
    fee basis through a broker-dealer sponsored mutual fund purchase program;
 
  . clients of investment advisers, financial planners or other financial
    intermediaries that charge periodic or asset-based fees for their
    services.
 
  . any eligible employer-sponsored qualified defined contribution retirement
    plan. Eligible plans are those with at least 25 employees and which
    either (a) make an initial purchase of one or more Nuveen Mutual Funds
    aggregating $500,000 or more or (b) execute a Letter of Intent to
    purchase in the aggregate $500,000 or more of fund shares. Nuveen will
    pay Authorized Dealers a sales commission on such purchases equal to 1%
    of the first $2.5 million, plus 2.5% of any amount purchased over $5.0
    million. For this category of investors a contingent deferred sales
    charge of 1% will be assessed on redemptions within 18 months of
    purchase, unless waived. Municipal bond funds are not a suitable
    investment for individuals investing in retirement plans.
 
  Holders of Class C Shares acquired on or before January 31, 1997 can convert
those shares to Class A Shares of the same fund at the shareholder's
affirmative request six years after the date of purchase. Holders of Class C
Shares must submit their request to the transfer agent no later than the last
business day of the 71st month following the month in which they purchased
their shares. Holders of Class C Shares purchased after that date will not have
the option to convert those shares to Class A Shares.
 
  Class B Shares will automatically convert to Class A Shares eight years after
purchase. The purpose of the conversion is to limit the distribution fees you
pay over the life of your investment. All conversions will be done at net asset
value without the imposition of any sales load, fee, or other charge, so that
the value of each shareholder's account immediately before conversion will be
the same as the value of the account immediately after conversion. Class B
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 B Shares acquired through reinvestment of distributions
will be attributed to particular purchases of Class B Shares in accordance with
such procedures as the Board of Trustees may determine from time to time. Class
B Shares that are converted to Class A Shares will remain subject to an annual
service fee that is identical in amount for both Class B Shares and Class A
Shares. Since net asset value per share of the Class B 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 B Shares converted. Any
conversion of Class B Shares into Class A Shares will be subject to the
 
                                      S-46
<PAGE>
 
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 B Shares into Class A Shares might be suspended if such an opinion or
ruling were no longer available.
 
  Any Class A Shares purchased pursuant to a special sales charge waiver must
be acquired for investment purposes and on the condition that they will not be
transferred or resold except through redemption by the Funds. You or your
financial adviser must notify Nuveen or the Fund's transfer agent whenever you
make a purchase of Class A Shares of any Fund that you wish to be covered under
these special sales charge waivers.
 
  Class A Shares of any Fund may be issued at net asset value without a sales
charge in connection with the acquisition by a Fund of another investment
company. All purchases under the special sales charge waivers will be subject
to minimum purchase requirements as established by the Funds.
 
  In determining the amount of your purchases of Class A Shares of any Fund
that may qualify for a reduced sales charge, the following purchases may be
combined: (1) all purchases by a trustee or other fiduciary for a single trust,
estate or fiduciary account; (2) all purchases by individuals and their
immediate family members (i.e., their spouses, parents, children, grandparents,
grandchildren, parents-in-law, sons- and daughters-in-law, siblings, a
sibling's spouse, and a spouse's siblings); or (3) all purchases made through a
group purchase program as described above.
 
  Class R Share Purchase Eligibility. Class R Shares are available for
purchases of $2.5 million or more and for purchases using dividends and capital
gains distributions on Class R Shares. Class R Shares also are available for
the following categories of investors:
 
  . officers, trustees and former trustees of the Nuveen and Flagship Funds
    and their immediate family members or trustees/directors of any fund,
    sponsored by Nuveen, any parent company of Nuveen and subsidiaries
    thereof and their immediate family members;
 
  . bona fide, full-time and retired employees of Nuveen, any parent company
    of Nuveen, and subsidiaries thereof, or their immediate family members;
 
  . any person who, for at least 90 days, has been an officer, director or
    bona fide employee of any Authorized Dealer, or their immediate family
    members;
 
  . officers and directors of bank holding companies that make Fund shares
    available directly or through subsidiaries or bank affiliates, or their
    immediate family members;
 
  . bank or broker-affiliated trust departments investing funds over which
    they exercise exclusive discretionary investment authority and that are
    held in a fiduciary, agency, advisory, custodial or similar capacity;
 
  . investors purchasing on a periodic fee, asset-based fee or no transaction
    fee basis through a broker-dealer sponsored mutual fund purchase program;
 
  . clients of investment advisers, financial planners or other financial
    intermediaries that charge periodic or asset-based fees for their
    services.
  . Any shares purchased by investors falling within any of the first four
    categories listed above must be acquired for investment purposes and on
    the condition that they will not be transferred or resold except through
    redemption by the fund.
 
In addition, purchasers of Nuveen Defined Portfolios may reinvest their
distributions from such Defined Portfolios in Class R Shares, if, before
September 6, 1994, such purchasers had elected to reinvest distributions
 
                                      S-47
<PAGE>
 
in Nuveen Fund shares (before June 13, 1995 for Nuveen Municipal Bond Fund
shares). Shareholders may exchange their Class R Shares of any Nuveen Fund into
Class R Shares of any other Nuveen Fund.
 
  The reduced sales charge programs may be modified or discontinued by the
Funds at any time upon prior written notice to shareholders of the Funds.
 
  For more information about the purchase of Class A Shares or reduced sales
charge programs, or to obtain the required application forms, call Nuveen toll-

REDUCTION OR ELIMINATION OF CONTINGENT DEFERRED SALES CHARGE
 
  Class A Shares are normally redeemed at net asset value, without any
Contingent Deferred Sales Charge ("CDSC"). However, in the case of Class A
Shares purchased at net asset value on or after July 1, 1996 because the
purchase amount exceeded $1 million, where the Authorized Dealer did not waive
the sales commission, a CDSC of 1% is imposed on any redemption within 18
months of purchase. In the case of Class B Shares redeemed within six years of
purchase, a CDSC is imposed, beginning at 5% for redemptions within the first
year, declining to 4% for redemptions within years two and three, and declining
by 1% each year thereafter until disappearing after the sixth year. Class C
Shares are redeemed at net asset value, without any CDSC, except that a CDSC of
1% is imposed upon redemption of Class C Shares that are redeemed within 12
months of purchase.
 
  In determining whether a CDSC is payable, a Fund will first redeem shares not
subject to any charge, or that represent an increase in the value of a Fund
account due to capital appreciation, and then will redeem shares held for the
longest period, unless the shareholder specifies another order. No CDSC is
charged on shares purchased as a result of automatic reinvestment of dividends
or capital gains paid. In addition, no CDSC will be charged on exchanges of
shares into another Nuveen Mutual Fund or Nuveen Money Market fund. The holding
period is calculated on a monthly basis and begins the first day of the month
in which the order for investment is received. The CDSC is calculated based on
the lower of the redeemed shares' cost or net asset value at the time of the
redemption and is deducted from the redemption proceeds. Nuveen receives the
amount of any CDSC shareholders pay. If shares subject to a CDSC are exchanged
for shares of a Nuveen money market fund, the CDSC would be imposed on the
subsequent redemption of those money market shares, and the period during which
the shareholder holds the money market fund shares would be counted in
determining the remaining duration of the CDSC. The Fund may elect not to so
count the period during which the shareholder held the money market fund
shares, in which event the amount of any applicable CDSC would be reduced in
accordance with applicable SEC rules by the amount of any 12b-1 plan payments
to which those money market funds shares may be subject.
 
  The CDSC may be waived or reduced under the following six special
circumstances: 1) redemptions within one year following the death or
disability, as defined in Section 72(m)(7) of the Internal Revenue Code of
1986, as amended, of a shareholder; 2) in whole or in part for redemptions of
shares by shareholders with accounts in excess of specified breakpoints that
correspond to the breakpoints under which the up-front sales charge on Class A
Shares is reduced pursuant to Rule 22d-1 under the Act; 3) redemptions of
shares purchased under circumstances or by a category of investors for which
Class A Shares could be purchased at net asset value without a sales charge; 4)
in connection with the exercise of a reinstatement privilege whereby the
proceeds of a redemption of a Fund's shares subject to a sales charge are
reinvested in shares of certain Funds within a specified number of days; 5) in
connection with the exercise of a Fund's right to redeem all shares in an
account that does not maintain a certain minimum balance or that the applicable
board has determined may have material adverse consequences to the shareholders
of such Fund; and 6) redemptions made pursuant to a Fund's systematic
withdrawal plan, up to 12% of the current market value. If a Fund waives or
reduces the CDSC,
 
                                      S-48
<PAGE>
 
such waiver or reduction would be uniformly applied to all Fund shares in the
particular category. In waiving or reducing a CDSC, the Funds will comply with
the requirements of Rule 22d-1 of the Investment Company Act of 1940, as
amended.
 
GENERAL MATTERS
 
  The Funds may encourage registered representatives and their firms to help
apportion their assets among bonds, stocks and cash, and may seek to
participate in programs that recommend a portion of their assets be invested in
tax-free, fixed income securities.
 
  In addition to the types of compensation to dealers to promote sales of fund
shares that are described in the prospectus, Nuveen may from time to time make
additional reallowances only to certain authorized dealers who sell or are
expected to sell certain minimum amounts of shares of the Nuveen mutual funds
during specified time periods.
 
  To help advisers and investors better understand and most efficiently use the
Funds to reach their investment goals, the Funds may advertise and create
specific investment programs and systems. For example, this may include
information on how to use the Funds to accumulate assets for future education
needs or periodic payments such as insurance premiums. The Funds may produce
software, electronic information sites, or additional sales literature to
promote the advantages of using the Funds to meet these and other specific
investor needs.
 
  Exchanges of shares of a Fund for shares of a Nuveen Money Market fund may be
made on days when both funds calculate a net asset value and make shares
available for public purchase. Shares of the Nuveen money market funds may be
purchased on days on which the Federal Reserve Bank of Boston is normally open
for business. In addition to the holidays observed by the Fund, the Nuveen
money market funds observe and will not make fund shares available for purchase
on the following holidays: Martin Luther King's Birthday, Columbus Day and
Veterans Day.
 
  In addition, you may exchange Class R Shares of any Fund for Class A Shares
of the same Fund without a sales charge if the current net asset value of those
Class R Shares is at least $3,000 or you already own Class A Shares of that
Fund.
 
  Each Fund may suspend the right of redemption, or delay payment to redeeming
shareholders for more than seven days, when the New York Stock Exchange is
closed (not including customary weekend and holiday closings); when trading in
the markets a Fund normally uses is restricted, or the SEC determines that an
emergency exists so that trading of a Fund's portfolio securities or
determination of a Fund's net asset value is not reasonably practical; or the
SEC by order permits the suspension of the right of redemption or the delay in
payment to redeeming shareholders for more than seven days.
 
  The Funds have reserved the right to redeem in kind (that is, to pay
redemption requests in cash and portfolio securities, or wholly in portfolio
securities), although the Funds have no present intention to redeem in kind.
The Funds voluntarily have committed to pay in cash all requests for redemption
by any shareholder, limited as to each shareholder during any ninety-day period
to the lesser of $250,000 or 1% of the net asset value of a Fund at the
beginning of the ninety-day period.
 
  Shares will be registered in the name of the investor or the investor's
financial adviser. A change in registration or transfer of shares held in the
name of a financial adviser may only be made by an order in good form from the
financial adviser acting on the investor's behalf. Share certificates will only
be issued upon written request to the Funds' transfer agent. No share
certificates will be issued for fractional shares.
 
  For more information on the procedure for purchasing shares of a Fund and on
the special purchase programs available thereunder, see "How to Buy Shares" in
the Prospectus.

  Nuveen serves as the principal underwriter of the shares of the Funds
pursuant to a "best efforts" arrangement as provided by a distribution
agreement with the Nuveen Flagship Multistate Trust IV, dated February 1, 1997
and last renewed on July 31, 1998 ("Distribution Agreement"). Pursuant to the
Distribution Agreement, the Trust appointed Nuveen to be its agent for the
distribution of the Funds' shares on a continuous offering basis. Nuveen sells
shares to or through brokers, dealers, banks or other qualified financial
intermediaries (collectively referred to as "Dealers"), or others, in a manner
consistent with the then effective registration statement of the Trust.
Pursuant to the Distribution Agreement, Nuveen, at its own expense, finances
certain activities incident to the sale and distribution of the Funds' shares,
including printing and distributing of prospectuses and statements of
additional information to other than existing shareholders, the printing and
distributing of sales literature, advertising and payment of compensation and
giving of concessions to Dealers. Nuveen receives for its services the excess,
if any, of the sales price of the Funds' shares less the net asset value of
those shares, and reallows a majority or all of such amounts to the Dealers who
sold the shares; Nuveen may act as such a Dealer. Nuveen also receives
compensation pursuant to a distribution plan adopted by the Trust pursuant to
Rule 12b-1 and described herein under "Distribution and Service Plan." Nuveen
receives any CDSCs imposed on redemptions of Shares.
 
  The following table sets forth the aggregate amount of underwriting
commissions with respect to the sale of Fund shares and the amount thereof
retained by Nuveen (or Flagship Financial Inc., which Nuveen acquired on
January 1, 1997) for each of the Funds for the last three fiscal years. All
figures are to the nearest thousand.

DISTRIBUTION AND SERVICE PLAN
 
  The Funds have adopted a plan (the "Plan") pursuant to Rule 12b-1 under the
Investment Company Act of 1940, which provides that Class B Shares and Class C
Shares will be subject to an annual distribution fee, and that Class A Shares,
Class B Shares and Class C Shares will be subject to an annual service fee.
Class R Shares will not be subject to either distribution or service fees.
 
  The distribution fee applicable to Class B and Class C Shares under each
Fund's Plan will be payable to reimburse Nuveen for services and expenses
incurred in connection with the distribution of Class B and Class C Shares,
respectively. These expenses include payments to Authorized Dealers, including
Nuveen, who are brokers of record with respect to the Class B and Class C
Shares, as well as, without limitation, expenses of printing and distributing
prospectuses to persons other than shareholders of the Fund, expenses of
preparing, printing and distributing advertising and sales literature and
reports to shareholders used in connection with the sale of Class B and Class C
Shares, certain other expenses associated with the distribution of Class B and
Class C Shares, and any distribution-related expenses that may be authorized
from time to time by the Board of Trustees.
 
  The service fee applicable to Class A Shares, Class B Shares and Class C
Shares under each Fund's Plan will be payable to Authorized Dealers in
connection with the provision of ongoing account services to shareholders.
 
                                      S-50
<PAGE>
 
These services may include establishing and maintaining shareholder accounts,
answering shareholder inquiries and providing other personal services to
shareholders.
 
  Each Fund may spend up to .20 of 1% per year of the average daily net assets
of Class A Shares as a service fee under the Plan applicable to Class A Shares.
Each Fund may spend up to .75 of 1% per year of the average daily net assets of
Class B Shares as a distribution fee and up to .20 of 1% per year of the
average daily net assets of Class B Shares as a service fee under the Plan
applicable to Class B Shares. Each Fund may spend up to .55 of 1% per year of
the average daily net assets of Class C Shares as a distribution fee and up to
 .20 of 1% per year of the average daily net assets of Class C Shares as a
service fee under the Plan applicable to Class C Shares.
 
  For the fiscal year ended May 31, 1998, 100% of service fees and distribution
fees were paid out as compensation to Authorized Dealers. The service fee for
Class A and Class C Shares was .20% and the distribution fee for Class B Shares
was .75% and for Class C Shares was .55% (.35% for the Kentucky Limited Term
Fund Class C Shares).

  Under each Fund's Plan, the Fund will report quarterly to the Board of
Trustees for its review all amounts expended per class of shares under the
Plan. The Plan may be terminated at any time with respect to any class of
shares, without the payment of any penalty, by a vote of a majority of the
trustees who are not "interested persons" and who have no direct or indirect
financial interest in the Plan or by vote of a majority of the

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

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

  Subsequent to its purchase by a Fund, an issue may cease to be rated or its
rating may be reduced below the minimum required for purchase by such Fund.
Neither event requires the elimination of such obligation from a Fund's
portfolio, but Nuveen Advisory will consider such an event in its determination
of whether the Fund should continue to hold such obligation.

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