NUVEEN INSURED MUNICIPAL BOND FUND
NUVEEN MASSACHUSETTS INSURED TAX-FREE VALUE FUND
NUVEEN NEW YORK INSURED TAX-FREE VALUE FUND
 
Nuveen Insured Tax-Free Bond Fund, Inc. is an open-end investment company
consisting of the three tax-free mutual funds named above (the "Funds"). Each
Fund represents a separate portfolio, which is designed to provide as high a
level of current interest income exempt from both regular federal income tax
and applicable state personal income tax as is consistent, in the view of the
Fund's management, with preservation of capital. Each Fund invests in long-term
Municipal Obligations which are either covered by insurance guaranteeing the
timely payment of principal and interest or backed by an escrow or trust
account containing sufficient U.S. Government or U.S. Government agency
securities to ensure timely payment of principal and interest. SEE PAGE 19 FOR
FURTHER INFORMATION ABOUT MUNICIPAL BOND INSURANCE. Each Fund invests in
Municipal Obligations judged by the Fund's investment adviser to offer the best
values among Municipal Obligations of similar credit quality. Nuveen Insured
Municipal Bond Fund (the "National Fund") purchases Municipal Obligations
issued within the 50 states and certain U.S. possessions or territories, while
Nuveen Massachusetts Insured Tax-Free Value Fund (the "Massachusetts Fund") and
Nuveen New York Insured Tax-Free Value Fund (the "New York Fund") purchase
Municipal Obligations issued within their respective states.
   
 Each Fund has adopted a Flexible Pricing Program designed to permit you and
your financial adviser to choose the method of purchasing shares that you
believe is most beneficial given the amount of your purchase and any current
holdings of Fund shares, the length of time you expect to hold your investment,
and other relevant circumstances. The Program features three alternative ways
to purchase Fund shares (Classes A, C and R), each with a different combination
of sales charges, ongoing fees, eligibility requirements, and other features.
See "Flexible Pricing Program," "How to Buy Fund Shares" and "Summary of Fund
Expenses."

(1) Authorized Dealers and other firms may independently charge additional fees
for shareholder transactions or for advisory services; please see their
materials for details.     
   
(2) Class R Shares are available for purchase only under certain limited
circumstances, or by specified investors, as described below under "How to Buy
Fund Shares--Class R Shares."     
   
(3) Reduced sales charges apply to purchases of $50,000 or more. See "How to
Buy Fund Shares--Class A Shares."     
   
(4) Class A purchases at net asset value of $1 million or more may be subject
to a 1% contingent deferred sales charge if redeemed within 18 months of
purchase. See "How to Buy Fund Shares--Class A Shares."     
   
(5) Class C Shares redeemed within one year of purchase are subject to a 1%
contingent deferred sales charge.     
   
(6) In order to prevent total operating expenses (excluding any distribution or
service fees) from exceeding .975 of 1% of the average daily net asset value of
any class of shares of a Fund, Nuveen Advisory has agreed to waive all or a
portion of its management fees or reimburse certain expenses of each Fund.
Nuveen Advisory may also voluntarily agree to reimburse additional expenses
from time to time, which voluntary reimbursements, may be terminated at any
time in its discretion.     
   
(7) Class C Shares are subject to an annual distribution fee of .75 of 1% of
average daily net assets to reimburse Nuveen for costs in connection with the
sale of Fund shares. Both Class A Shares and Class C Shares of each Fund are
subject to an annual service fee of .25 of 1% of average daily net assets to
compensate Authorized Dealers for ongoing account services. See "Distribution
and Service Plan." Long-term holders of Class C Shares may pay more in Rule
12b-1 distribution fees than the economic equivalent of the maximum front-end
sales charge permitted under the National Association of Securities Dealers
Rules of Fair Practice.     
                    
                 The purpose of the tables above is to help you understand all
                 expenses and fees that you would bear directly or indirectly
                 as a Fund shareholder. The expenses and fees shown are for
                 the fiscal year ended February 29, 1996.

                 *This example does not represent past or future expenses.
                 Actual expenses may be greater or less than those shown.
                 Moreover, a Fund's actual rate of return may be greater or
                 less than the hypothetical 5% return shown in this example.
                 This example assumes that the percentage amounts listed under
                 Annual Operating Expenses remain the same in each of the
                 periods. The ten-year figure for Class C Shares reflects the
                 automatic conversion of Class C Shares into Class A Shares
                 six years after purchase. Based on the foregoing assumptions,
                 the expenses incurred on an investment in Class C Shares will
                 exceed the expenses incurred on an investment in Class A
                 Shares sometime in the sixth year after purchase. You should
                 also note that Class R Shares are available for purchase only
                 under certain limited circumstances, or by specified
                 investors. For additional information about each Fund's fees
                 and expenses, see "Distribution and Service Plan" and
                 "Management of the Funds."     
                    
                 **Assumes that shareholder redeemed on the first day of the
                 second year and the contingent deferred sales charge was not
                 applicable for any of the periods shown. If the shareholder
                 had redeemed on the last day of the first year, the expenses
                 in the first year would have been $27 for the National and
                 New York Funds and $28 for the Massachusetts Fund.

                                    NUVEEN TAX-FREE MUTUAL FUNDS PROSPECTUS     
HOW TO DETERMINE IF ONE OF THE FUNDS IS RIGHT FOR YOU
                                                                  
                                                               JULY 1, 1996     
                 There are many reasons why you might invest in one of the
                 Funds. These can include:
                 . lowering the tax burden on your investment income
                 . earning regular monthly dividends
                 . seeking to preserve your investment capital
                 . systematically setting money aside for retirement, college
                   funding or estate planning purposes
 
                 While there can be no assurance that the Funds will enable
                 you to achieve your individual investment goals, they have
                 been designed for investors who have these kinds of
                 investment goals in mind.
 
                 In addition, each Fund incorporates the following features
                 and benefits. You should carefully review the more detailed
                 description of these features and benefits elsewhere in the
                 Prospectus to make sure they serve your individual investment
                 goals.
 
                 MONTHLY, TAX-FREE INCOME
                 Each Fund provides monthly dividends exempt from regular
                 federal income tax, and in the case of the Massachussetts and
                 New York Funds, from applicable state personal income taxes
                 for in-state residents.

                 DIVERSIFIED, INSURED PORTFOLIO
                 Each Fund purchases Municipal Obligations which are either
                 covered by insurance guaranteeing the timely payment of
                 principal and interest or backed by an escrow or trust
                 account containing sufficient U.S. Government or U.S.
                 Government agency securities to ensure timely payment of
                 principal and interest. The National Fund purchases Municipal
                 Obligations issued within the 50 states and certain U.S.
                 possessions or territories. The Massachusetts Fund and the
                 New York Fund purchase Municipal Obligations issued within
                 their respective states. Each Fund is diversified and
                 maintains diversity within its portfolio by selecting
                 Municipal Obligations of different issuers. Each Fund further
                 enhances its portfolio mix by purchasing Municipal
                 Obligations of different types and purposes, and the National
                 Fund also purchases Municipal Obligations from different
                 geographic regions across the country.
 
                 EXPERIENCED MANAGEMENT
                    
                 Each Fund is managed by Nuveen Advisory Corp. ("Nuveen
                 Advisory"), a wholly-owned subsidiary of John Nuveen & Co.
                 Incorporated ("Nuveen"). Founded in 1898, Nuveen is the
                 oldest and largest investment banking firm in the country
                 devoted exclusively to tax-exempt securities. Nuveen Advisory
                 currently manages 74 different tax-free portfolios
                 representing approximately $30 billion in assets.     
 
                 VALUE INVESTING
                 As a guiding policy, Nuveen Advisory's portfolio managers
                 seek undervalued, insured Municipal Obligations which offer
                 the best values among Municipal Obligations of similar credit
                 quality. By selecting these Municipal Obligations, Nuveen
                 Advisory seeks to position each Fund better to achieve its
                 investment objective of as high a level of current interest
                 income exempt from both regular federal income tax and
                 applicable state personal income tax as is consistent, in the
                 view of the Fund's management, with preservation of capital,
                 regardless of which direction the market may move. Each
                 Fund's policy of investing in insured Municipal Obligations
                 may limit the extent to which it will achieve its value
                 investing strategy.

                 NUVEEN RESEARCH
                    
                 Nuveen Advisory's portfolio managers call upon the resources
                 of Nuveen's Research Department, the largest in the
                 investment banking industry devoted exclusively to tax-exempt
                 securities. Nuveen research analysts reviewed in 1995 more
                 than $100 billion of tax-exempt securities sold in new issue
                 and secondary markets.     
 
                 LOW MINIMUMS
                 You can start earning tax-free income with a low initial
                 investment of $1,000 in a particular class. See "How to Buy
                 Fund Shares."
                    
                 FLEXIBILITY IN PURCHASING FUND SHARES     
                    
                 Each Fund has adopted a Flexible Pricing Program which is
                 designed to permit you and your financial adviser to choose
                 the method of purchasing shares that you believe is most
                 beneficial given the amount of your investment and any
                 current holdings of Fund shares, the length of time you
                 expect to hold your investment, and other relevant
                 circumstances. The Program features three alternative ways to
                 purchase Fund shares (Classes A, C and R), each with a
                 different combination of sales charges, ongoing fees,
                 eligibility requirements, and other features. Please refer to
                 "Flexible Pricing Program," "How to Buy Fund Shares" and "How
                 to Redeem Fund Shares" for a discussion of the Program's
                 features and additional information about these three classes
                 of shares.     
                        
                 AUTOMATIC DEPOSIT PLANS
                 The Funds offer a number of investment options, including
                 automatic deposit, direct deposit and payroll deduction, to
                 help you add to your account on a regular basis.
 
                 AUTOMATIC REINVESTMENT
                    
                 All monthly dividends or capital gains paid by your Fund on
                 each class of shares will be reinvested automatically into
                 additional shares of the same class without a sales charge
                 unless you elect to receive them in cash. Separately,
                 distributions from any Nuveen unit trust (a "Nuveen UIT") may
                 be used to buy Class A Shares and, under certain
                 circumstances, Class R Shares of a Fund, in either case
                 without a sales charge at net asset value.

<PAGE>
 
 
                 EXCHANGE PRIVILEGE
                    
                 Shares of a class may be quickly and easily exchanged by
                 telephone, without a sales charge, for shares of the same or
                 equivalent class of another Nuveen Mutual Fund or for shares
                 of certain Nuveen money market funds. Class R Shares of a
                 Fund may be exchanged for Class A Shares of the same Fund at
                 any time, provided that the current net asset value of those
                 Class R Shares is at least $1,000 or you already own Class A
                 Shares of that Fund.     
 
                 LIQUIDITY
                    
                 You may redeem all or a portion of your Fund shares on any
                 business day at the net asset value for the class of shares
                 you are redeeming. Class C Shares, as well as Class A
                 purchases of $1 million or more at net asset value, may be
                 subject to a contingent deferred sales charge ("CDSC") of 1%
                 upon redemption. Remember that share prices will fluctuate
                 with market conditions and upon redemption may be worth more
                 or less than their original cost. See "How to Redeem Fund
                 Shares."     
 
                 AUTOMATIC WITHDRAWAL
                 If you own shares totalling $10,000 or more, you can arrange
                 to have $50 or more sent to you from your account either
                 monthly or quarterly.
 
                 TELEPHONE REDEMPTIONS
                 You may establish free telephone redemption privileges for
                 your account.
       
                 RISKS AND SPECIAL CONSIDERATIONS
                    
                 You should consider certain other factors about the Funds
                 before investing. As with other bond mutual funds or any
                 long-term fixed-income investment, the value of a Fund's
                 portfolio will tend to vary inversely with changes in
                 prevailing interest rates. Accordingly, each Fund should be
                 considered a long-term investment, designed to provide the
                 best results when held for a multi-year period. A Fund may
                 not be suitable if you have a short-term investment horizon.
                 Additionally, the portfolio of the Massachusetts Fund and the
                 New York Fund may each be susceptible to political, economic
                 or regulatory developments affecting issuers of Municipal
                 Obligations in its state. The Funds also have the ability to
                 engage in certain

                 investment practices, including the purchase of Municipal
                 Obligations that pay interest subject to the federal
                 alternative minimum tax, the purchase or sale of securities
                 on a when-issued or delayed delivery basis, the purchase or
                 sale of municipal lease and installment purchase obligations,
                 and the purchase or sale of futures or options for hedging
                 purposes. The National Fund to date has not invested in
                 Municipal Obligations that pay interest subject to the
                 federal alternative minimum tax and has no present intention
                 of doing so. As described elsewhere in this Prospectus, the
                 Funds have no present intention of purchasing or selling
                 futures or options, and may engage in the other investment
                 practices listed above only under strict limits.

WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES AND POLICIES?

                 INVESTMENT OBJECTIVE     
Each Fund is        
designed to      The investment objective of each Fund is to provide you with
provide income   as high a level of current interest income exempt from both
free from        regular federal income tax and applicable state personal
federal and      income tax as is consistent, in the view of the Fund's
applicable       management, with preservation of capital. There can be no
state personal   assurance that the investment objective of any Fund will be
income taxes     achieved. The investment objective is a fundamental policy of
                 each Fund and may not be changed without the approval of the
                 holders of a majority of the shares of that Fund. Other
                 investment restrictions that may be changed only with
                 shareholder approval are contained in the Statement of
                 Additional Information. [/R]
                    
                 HOW THE FUNDS PURSUE THEIR OBJECTIVES     
                 
    
   
The Funds seek   Nuveen Advisory believes that in any market environment there
insured          are quality Municipal Obligations whose current price, yield,
Municipal        credit quality and future prospects make them seem
Obligations      underpriced or exceptionally attractive when compared with
considered to    other Municipal Obligations in the market. Value investing
be undervalued   for the Funds will ordinarily involve purchases of
                 undervalued or underrated uninsured Municipal Obligations
                 which would then be covered by insurance, or undervalued
                 insured Municipal Obligations. In selecting investments for
                 the Funds, Nuveen Advisory will attempt to identify and
                 purchase those undervalued, insured Municipal Obligations
                 that offer the best values among Municipal Obligations of
                 similar credit quality. By selecting these Municipal
                 Obligations, each Fund will seek to provide attractive
                 current tax-free income and to protect the Fund's net asset
                 value in both rising and declining markets. In this way,
                 regardless of the direction the market may move, value
                 investing, if successful, will better position each Fund to
                 achieve its investment objective of as high a level of
                 current interest income exempt from both regular federal
                 income tax and applicable state personal income tax as is
                 consistent, in the view of the Fund's management, with
                 preservation of capital. Each Fund's policy of investing in
                 insured Municipal Obligations may limit the extent to which
                 it will achieve its value investing strategy. Any net capital
                 appreciation realized by a Fund will generally result in the
                 distribution of taxable capital gains to Fund shareholders.

                 Successful value investing depends on identifying and
Thorough         purchasing undervalued securities before the rest of the
research can     marketplace finds them. Nuveen Advisory believes the
help identify    municipal market provides these opportunities, in part
values           because of the relatively large number of issuers of tax-
                 exempt securities and the relatively small number of full-
                 time, professional municipal market analysts. For example,
                 there are currently
 
                                        17
<PAGE>
 
                 about 7,500 common stocks that are followed by about 23,000
                 analysts. By contrast, there are about 60,000 entities that
                 issue tax-exempt securities and less than 1,000 professional
                 municipal market analysts.
 
                 Nuveen and Nuveen Advisory believe that together they employ
                 the largest number of research analysts in the investment
                 banking industry devoted exclusively to the review and
                 surveillance of tax-exempt securities. Their team of more
                 than 40 individuals has over 350 years of combined municipal
                 market experience. Nuveen and Nuveen Advisory have access to
                 information on approximately 60,000 municipal issuers, and
                 review annually more than $100 billion of tax-exempt
                 securities sold in new issue and secondary markets.
 
                 The National Fund will invest primarily in Municipal
                 Obligations issued within the 50 states and certain U.S.
Which            possessions or territories so that the interest income on the
Municipal        Municipal Obligations will be exempt from regular federal
Obligations      income tax, although this income may be subject to applicable
are selected     state personal income taxes. The Massachusetts Fund and the
as               New York Fund will invest primarily in Municipal Obligations
investments?     issued within their respective states so that the interest
                 income on the Municipal Obligations will be exempt from both
                 regular federal and applicable state personal income taxes.
                 Because of the different credit characteristics of
                 governmental authorities in a state and because of differing
                 supply and demand factors for a state's Municipal
                 Obligations, there may be differences in the yields on each
                 Fund's classes of shares and in the degree of market and
                 financial risk to which each Fund is subject.
 
                 Under ordinary circumstances, each Fund will invest (1)
Each Fund will   substantially all (at least 80%) of its net assets in
seek to          Municipal Obligations which are either covered by insurance
purchase         guaranteeing the timely payment of principal and interest or
insured          backed by an escrow or trust account containing sufficient
Municipal        U.S. Government or U.S. Government agency securities to
Obligations      ensure timely payment of principal and interest, and (2) not
                 more than 20% of its net assets in "temporary investments,"
                 within the limitations and for the purposes described below,
                 provided that temporary investments subject to regular
                 federal income tax and Municipal Obligations that pay
                 interest subject to the federal alternative minimum tax ("AMT
                 Bonds") may not comprise more than 20% of each Fund's net
                 assets.
 
                 Each Fund may only invest in Municipal Obligations rated
                 investment-grade at the time of purchase (Baa or BBB or
                 better) by Moody's Investors Service, Inc. ("Moody's") or
                 Standard and Poor's Corporation ("S&P"), or in unrated
                 Municipal Obligations of investment grade quality in the
                 opinion of Nuveen Advisory, with no

                                                               JULY 1, 1996     
                 fixed percentage limitations on these unrated securities.
                 Municipal Obligations rated Baa are considered by Moody's to
                 be medium grade obligations which lack outstanding investment
                 characteristics and in fact have speculative characteristics
                 as well, while Municipal Obligations rated BBB are regarded
                 by S&P as having an adequate capacity to pay principal and
                 interest. The Funds may invest up to 20% of their net assets
                 in AMT Bonds, although the National Fund to date has not done
                 so and has no present intention of doing so. All of the Funds
                 intend to emphasize investments in Municipal Obligations with
                 long-term maturities in order to maintain an average
                 portfolio maturity of 20-30 years, but the average maturity
                 may be shortened from time to time depending on market
                 conditions in order to help limit each Fund's exposure to
                 market risk. As a result, each Fund's portfolio at any given
                 time may include both long-term and intermediate-term
                 Municipal Obligations.
 
                 The foregoing investment policies are fundamental policies of
                 each Fund and may not be changed without the approval of the
                 holders of a majority of the shares of that Fund.
   
Municipal Obligations
can be insured
in one of
three ways
    
                 Each insured Municipal Obligation held by a Fund will either
                 be (1) covered by an insurance policy applicable to a
                 specific security and obtained by the issuer of the security
                 or a third party at the time of original issuance ("Original
                 Issue Insurance"), (2) covered by an insurance policy
                 applicable to a specific security and obtained by the Fund or
                 a third party subsequent to the time of original issuance
                 ("Secondary Market Insurance"), or (3) covered by a master
                 municipal insurance policy purchased by the Fund ("Portfolio
                 Insurance"). Each Fund currently maintains policies of
                 Portfolio Insurance with MBIA Insurance Corporation, AMBAC
                 Indemnity Corporation, Financial Security Assurance, Inc.,
                 and Financial Guaranty Insurance Company, and may in the
                 future obtain other policies of Portfolio Insurance depending
                 on the availability of these policies on terms favorable to
                 the Fund. However, a Fund may determine not to obtain these
                 policies and to emphasize investments in Municipal
                 Obligations insured under Original Issue Insurance or
                 Secondary Market Insurance. In any event, a Fund will only
                 obtain policies of Portfolio Insurance issued by mono-line
                 insurers specializing in insuring municipal debt, whose
                 claims-paying ability is rated Aaa by Moody's or AAA by S&P.
                 In determining whether to insure Municipal Obligations held
                 by a Fund, an insurer will apply its own standards, which
                 correspond generally to the standards it has established for
                 determining the insurability of new issues of Municipal
                 Obligations. See the Statement of Additional Information for
                 further information about each type of insurance described
                 above.
 
                                         19
<PAGE>
 
 
                 In addition to insured Municipal Obligations, a Fund may
                 invest in Municipal Obligations that are entitled to the
                 benefit of an escrow or trust account which contains
                 securities issued or guaranteed by the U.S. Government or
                 U.S. Government agencies, backed by the full faith and credit
                 of the United States, and sufficient in amount to ensure the
                 payment of interest and principal on the original interest
                 payment and maturity dates ("collateralized obligations").
                 Collateralized obligations generally will not be insured and
                 are regarded as having the credit characteristics of the
                 underlying U.S. Government or U.S. Government agency
                 securities. Uninsured collateralized obligations will not
                 constitute more than 20% of each Fund's net assets.
   
The Funds may
insure
permanently
Municipal Obligations
covered by
Portfolio
Insurance     
                 One or more policies of Portfolio Insurance may provide a
                 Fund, pursuant to an irrevocable commitment of the insurer,
                 with the option to exercise the right to obtain permanent
                 insurance ("Permanent Insurance") with respect to a Municipal
                 Obligation that is to be sold by the Fund. A Fund would
                 exercise the right to obtain Permanent Insurance upon payment
                 of a single, predetermined insurance premium payable from the
                 proceeds of the sale of that Municipal Obligation. It is
                 expected that a Fund will exercise the right to obtain
                 Permanent Insurance for a Municipal Obligation only if, in
                 the opinion of Nuveen Advisory, upon exercise the net
                 proceeds from the sale by the Fund of that obligation, as
                 insured, would exceed the proceeds from the sale of that
                 obligation without insurance.
                    
                 Premiums for a Portfolio Insurance policy are paid by the
                 Funds monthly, and are adjusted for purchases and sales of
                 Municipal Obligations covered by the policy during the month.
                 The yield on each of the Funds is reduced to the extent of
                 the insurance premiums allocated to it. Depending upon the
                 characteristics of the Municipal Obligations held by the
                 Funds, the annual premium rate for the policies of Portfolio
                 Insurance is estimated to range from .15% to .30% of the
                 value of the Municipal Obligations covered under the
                 policies. Because the majority of the Municipal Obligations
                 in each Fund were not covered by policies of Portfolio
                 Insurance during the fiscal year ended February 29, 1996,
                 total premiums as a percentage of the value of Municipal
                 Obligations held by each Fund (.00%, .01% and .00%) for the
                 National Fund, the Massachusetts Fund and the New York Fund,
                 respectively, were significantly less than the estimated
                 rate.

                                    NUVEEN TAX-FREE MUTUAL FUNDS PROSPECTUS     
                                                                  
                                                               JULY 1, 1996     
                 DESCRIPTION OF THE FUNDS' INVESTMENTS
                 Municipal Obligations, as the term is used in this
Municipal        Prospectus, are federally tax-exempt debt obligations issued
Obligations      by states, cities and local authorities and by certain U.S.
are issued by    possessions or territories to obtain funds for various public
states, cities   purposes, such as the construction of public facilities, the
and local        payment of general operating expenses and the refunding of
authorities to   outstanding debts. They may also be issued to obtain funding
support a        for various private activities, including loans to finance
variety of       the construction of housing, educational and medical
public           facilities or privately owned industrial development and
activities       pollution control projects.
    
                 The two principal classifications of Municipal Obligations
                 are general obligation and revenue bonds. GENERAL OBLIGATION
                 bonds are secured by the issuer's pledge of its full faith,
                 credit and taxing power for the payment of principal and
                 interest. REVENUE bonds are payable only from the revenues
                 derived from a particular facility or class of facilities or,
                 in some cases, from the proceeds of a special excise or other
                 specific revenue source. Industrial development and pollution
                 control bonds are in most cases revenue bonds and do not
                 generally constitute the pledge of the credit or taxing power
                 of the issuer of these bonds.
 
                 Municipal Obligations may also include participations in
                 lease obligations or installment purchase contract
                 obligations (collectively, "lease obligations") of municipal
                 authorities or entities. Certain "non-appropriation" lease
                 obligations may present special risks because the
                 municipality's obligation to make future lease or installment
                 payments depends on money being appropriated each year for
                 this purpose. Each Fund will seek to minimize these risks by
                 not investing more than 10% of its assets in non-
                 appropriation lease obligations, and by only investing in
                 those non-appropriation lease obligations that meet certain
                 criteria of the Fund. See the Statement of Additional
                 Information for further information about lease obligations.
 
                 The yields on Municipal Obligations depend on a variety of
                 factors, including the condition of financial markets in
                 general and the municipal market in particular, as well as
                 the size of a particular offering, the maturity of the
                 obligation and the rating of the issue. Certain Municipal
                 Obligations may pay variable or floating rates of interest
                 based upon certain market rates or indexes such as a bank
                 prime rate or a tax-exempt money market index. The ratings of
                 Moody's and S&P represent their opinions as to the quality of
                 the Municipal Obligations that they undertake to rate. It
                 should be emphasized, however, that ratings are general and
                 are not absolute standards of quality. Consequently,
                 Municipal Obligations with the same maturity,

                 coupon and rating may have different yields, while those
                 having the same maturity and coupon with different ratings
                 may have the same yield. The market value of Municipal
                 Obligations will vary with changes in prevailing interest
                 rate levels and as a result of changing evaluations of the
                 ability of their issuers to meet interest and principal
                 payments. Similarly, the market value and net asset value of
                 shares of the Funds will change in response to interest rate
                 changes; they will tend to decrease when interest rates rise
                 and increase when interest rates fall.
                 
    
   
Temporary        As described above, each Fund under ordinary circumstances
investments      may invest up to 20% of its net assets in "temporary
will be U.S.     investments," but may invest without limit in temporary
Government or    investments during temporary defensive periods in order to
high quality     limit the exposure of its portfolio to market risk from
securities       temporary imbalances of supply and demand or other temporary
                 circumstances affecting the municipal market. Each Fund will
                 seek to make temporary investments in short-term securities
                 the interest on which is exempt from regular federal income
                 tax, but may be subject to state income tax in a Fund's
                 respective state. If suitable federally tax-exempt temporary
                 investments are not available at reasonable prices and
                 yields, a Fund may make temporary investments in taxable
                 securities whose interest is subject to both state and
                 federal income taxes. A Fund will invest only in those
                 taxable temporary investments that are either U.S. Government
                 securities or are rated within the highest grade by Moody's
                 or S&P, and mature within one year from the date of purchase
                 or carry a variable or floating rate of interest. A Fund will
                 not be in a position to achieve its investment objective of
                 tax-exempt income to the extent it invests in taxable
                 temporary investments. See the Statement of Additional
                 Information for further information about the temporary
                 investments in which the Funds may invest. [/R]
 
                 SPECIAL FACTORS PERTAINING TO STATE FUNDS
                 Because the Massachusetts Fund and the New York Fund will
                 concentrate their investments in Municipal Obligations issued
                 within their respective states, they may be affected by
                 political, economic or regulatory factors that may impair the
                 ability of issuers in their states to pay interest on or to
                 repay the principal of their debt obligations. These special
                 factors for each state are briefly described in Appendix A to
                 this Prospectus. See the Statement of Additional Information
                 for further information about these factors.

                 A Fund may purchase and sell Municipal Obligations on a when-
When-issued or   issued or delayed delivery basis, which calls for the Fund to
delayed          make payment or take delivery at a future date, normally 15-
delivery         45 days after the trade date. The commitment to purchase
transactions     securities on a when-issued or delayed delivery basis may
                 involve an element of risk because the value of the
                 securities is subject to market fluctuation, no interest
                 accrues to the purchaser prior to settlement of the
                 transaction, and at the time of delivery the market value may
                 be less than cost. A Fund commonly engages in when-issued
                 transactions in order to purchase or sell newly-issued
                 Municipal Obligations, and may engage in delayed delivery
                 transactions in order to manage its operations more
                 effectively. See the Statement of Additional Information for
                 further information about when-issued and delayed delivery
                 transactions.

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

                 may qualify for a reduced sales charge or a sales charge
                 waiver on a purchase of Class A Shares, as described below
                 under "How the Sales Charge on Class A Shares May Be Reduced
                 or Waived." Class R Shares are available for purchase at a
                 price equal to their net asset value, but only under certain
                 circumstances or for certain categories of investors, as
                 described below under "How to Buy Fund Shares--Class R
                 Shares."     
                    
                 In deciding whether to purchase Class A Shares, Class C
                 Shares or Class R Shares of a Fund, you should consider all
                 relevant factors, including the dollar amount of your
                 purchase, the length of time you expect to hold the shares
                 and whether a CDSC would apply, the amount of any applicable
                 up-front sales charge, the amount of any applicable
                 distribution or service fee that may be incurred while you
                 own the shares, and whether or not you will be reinvesting
                 income or capital gain distributions in additional shares,
                 whether or not you meet applicable eligibility requirements
                 or qualify for a sales charge waiver or reduction, and the
                 relative level of services that your financial adviser may
                 provide to different classes. Authorized Dealers and other
                 persons distributing a Fund's shares may receive different
                 compensation for selling different classes of shares.     
                 
    
   
Differences      Each class of shares of a Fund represents an interest in the
between the      same portfolio of investments. Each class of shares of a Fund
classes of       is identical in all respects except that each class has its
shares           own sales charge structure, each class bears its own class
                 expenses, including service and distribution fees, and each
                 class has exclusive voting rights with respect to any
                 distribution or service plan applicable to its shares. In
                 addition, the Class C Shares are subject to a conversion
                 feature and a CDSC of 1% if purchased on or after June 13,
                 1995 and redeemed within 12 months of purchase, as described
                 below. As a result of the differences in the expenses borne
                 by each class of shares, and differences in the purchase and
                 redemption activity for each class, net income per share,
                 dividends per share and net asset value per share will vary
                 among each Fund's classes of shares. [/R]

                 Exchange Commission takes the position that dealers who
                 receive 90% or more of the applicable sales charge may be
                 deemed underwriters under the Securities Act of 1933, as
                 amended.
                    
                 Nuveen may also from time to time provide additional

                 Funds and Nuveen UITs during specified time periods. Such
                 promotional support may include providing sales literature to

                 benefit of such Authorized Dealers' representatives, seminars
                 for the public, and advertising and sales campaigns.
                 Specifically, Nuveen offers a program of advertising support
                 to Authorized Dealers under which Nuveen will pay or
                 reimburse the Authorized Dealer for up to one-half of
                 specified media costs incurred in the placement of
                 advertisements which jointly feature the Authorized Dealer
                 and Nuveen Funds and Nuveen UITs. Reimbursement to the
                 Authorized Dealer will be based on the number of its
                 financial advisers who have sold Nuveen Fund shares and UIT
                 units during the prior calendar year according to an
                 established schedule. Any such support would be provided by
                 Nuveen out of its own assets, and not out of the assets of
                 the Funds, and will not change the price an investor pays for
                 sales or the amount that a Fund will receive from such a
                 sale.

                 front sales charge or ongoing distribution fee is imposed,

Letter of        You may qualify for a reduced sales charge on a purchase of
Intent           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
                 above. 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 SSI a
                 written Letter of Intent in a form acceptable to Nuveen. A
                 Letter of Intent states that you intend, but are not
                 obligated, to purchase over the next 13 months a stated total
                 amount of Class A Shares that would qualify you for a reduced
                 sales charge shown above. You may count shares of a Nuveen
                 Mutual Fund that you already own on which you paid an up-
                 front sales charge or an ongoing distribution fee and any
                 Class C Shares of a Nuveen Mutual Fund that you purchase over

                 program, but you will receive a reduced sales charge only on

                 13 months. You cannot count towards completion of your
                 investment program Class A Shares that you purchase without a
                 sales charge through investment of distributions from a
                 Nuveen Mutual Fund or a Nuveen UIT, or otherwise.
 
                 By establishing a Letter of Intent, you agree that your first
                 purchase of Class A Shares 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 SSI
                 whenever you make a purchase of Fund shares that you wish to
                 be covered under the Letter of Intent option.

                                                               JULY 1, 1996     
                    
                 An investor purchasing Class C Shares agrees to pay a CDSC of
                 1% if Class C Shares are redeemed within 12 months of
                 purchase. See "How to Redeem Fund Shares." The Class C shares
                 of the applicable Fund will effectively retain the CDSC; the
                 Fund will pay the amount of the CDSC to Nuveen, but will be
                 reimbursed by Nuveen in an equal amount by a reduction in the
                 distribution fees payable to Nuveen.     
                    
                 Class C Shares will automatically convert to Class A Shares
                 six years after purchase. All such conversions will be done
                 at net asset value without the imposition of any sales
                 charge, fee, or other charge, so that the value of each
                 shareholder's account immediately before conversion will be
                 the same as the value of the account immediately after
                 conversion. Class C Shares acquired through reinvestment of
                 distributions will convert into Class A Shares based on the
                 date of the initial purchase to which such shares relate. For
                 this purpose, Class C Shares acquired through reinvestment of
                 distributions will be attributed to particular purchases of
                 Class C Shares in accordance with such procedures as the
                 Board of Directors may determine from time to time. The
                 automatic conversion of Class C Shares to Class A Shares six
                 years after purchase was designed to ensure that holders of
                 Class C Shares would pay over the six-year period a
                 distribution fee that is approximately the economic
                 equivalent of the one-time, up-front sales charge paid by
                 holders of Class A Shares on purchases of up to $50,000.
                 Class C Shares that are converted to Class A Shares will no
                 longer be subject to an annual distribution fee, but they
                 will remain subject to an annual service fee which is
                 identical in amount for both Class C Shares and Class A
                 Shares. Since net asset value per share of the Class C Shares
                 and the Class A Shares may differ at the time of conversion,
                 a shareholder may receive more or fewer Class A Shares than
                 the number of Class C Shares converted. Any conversion of
                 Class C Shares into Class A Shares will be subject to the
                 continuing availability of an opinion of counsel or a private
                 letter ruling from the Internal Revenue Service to the effect
                 that the conversion of shares would not constitute a taxable
                 event under federal income tax law. Conversion of Class C
                 Shares into Class A Shares might be suspended if such an
                 opinion or ruling were no longer available.

                 CLASS R SHARES
                 
    
   
Class R Shares   If you own Fund shares as of September 6, 1994, those shares
are offered at   have been designated as Class R Shares. Purchases of
their net        additional Class R Shares of any Fund, which will not be
asset value      subject to any sales charge or any distribution or service
                 fee, will be limited to the following circumstances. You may
                 purchase Class R Shares with monies representing
                 distributions from Nuveen-sponsored UITs if, prior to
                 September 6, 1994, you had purchased such UITs and elected to
                 reinvest distributions from such UITs in shares of a Fund.
                 You may also purchase Class R Shares with monies representing
                 dividends and capital gain distributions on Class R Shares of
                 a Fund. You may purchase Class R Shares if you are making a
                 purchase of $1 million or more of Fund shares in a single
                 transaction. Finally, you may purchase Class R Shares if you
                 are within the following specified categories of investors
                 who are also eligible to purchase Class A Shares at net asset
                 value without an up-front sales charge: officers, directors
                 and retired directors of the 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; bank or
                 broker-affiliated trust departments; investors who purchase
                 through broker-dealer sponsored mutual fund purchase programs
                 offered on a periodic fee, asset-based fee or no transaction
                 fee basis; and clients of investment advisers, financial
                 planners or other financial intermediaries that charge
                 periodic or asset-based fees for their services. [/R]
                           
                 If you are eligible to purchase either Class R Shares or
                 Class A Shares of a Fund without a sales charge at net asset
                 value, you should be aware of the differences between these
                 two classes of shares. Class A Shares are subject to an
                 annual service fee to compensate Authorized Dealers for
                 providing you with ongoing account services. Class R Shares
                 are not subject to a service fee and consequently holders of
                 Class R Shares may not receive the same types or levels of
                 services from Authorized Dealers. In choosing between Class A
                 Shares and Class R Shares, you should weigh the benefits of
                 the services to be provided by Authorized Dealers against the
                 annual service fee imposed upon the Class A Shares.

                 INITIAL AND SUBSEQUENT PURCHASES OF SHARES
   
The Funds        You may buy Fund shares through Authorized Dealers or by
offer a number   directing your financial adviser to call Nuveen toll-free at
of convenient    800.843.6765. You may pay for your purchase by Federal
ways to          Reserve draft or by check made payable to "Nuveen [        ]
purchase         Fund, Class [A], [C], [R]," delivered to the financial
shares           adviser through whom the investment is to be made for
                 forwarding to the Funds' shareholder services agent, SSI.
                 When making your initial investment, you must also furnish
                 the information necessary to establish your Fund account by
                 completing and enclosing with your payment the attached
                 Application Form. After your initial investment, you may make
                 subsequent purchases at any time by forwarding to SSI a check
                 in the amount of your purchase made payable to "Nuveen
                 [     ] Fund, Class [A], [C], [R]," and indicating on the
                 check your account number. All payments must be in U.S.
                 dollars and should be sent directly to SSI at its address
                 listed on the back cover of this Prospectus. A check drawn on
                 a foreign bank or payable other than to the order of a Fund
                 generally will not be acceptable. You may also wire Federal
                 Funds directly to SSI, but you may be charged a fee for this.
                 For instructions on how to make Fund purchases by wire
                 transfer, call Nuveen toll-free at 800.621.7227, between the
                 hours of 8:30 a.m. and 8:00 p.m. Eastern Time.     
 
                 MINIMUM INVESTMENT REQUIREMENTS
                 Generally, your first purchase of any class of a Fund's
                 shares must be for $1,000 or more. Additional purchases may
                 be in amounts of $100 or more. These minimums may be changed
                 at any time by the Funds. There are exceptions to these
                 minimums for shareholders who qualify under one or more of
                 the Funds' automatic deposit, group purchase or reinvestment
                 programs.
                    
                 PURCHASE PRICE     
                    
                 The price at which the purchase of Fund shares is effected is
                 based on the next calculation of the Fund's net asset value
                 after the order is placed. The Fund's net asset value per
                 share is determined as of 4:00 p.m. Eastern Time on each day
                 the New York Stock Exchange is open for business. See "Net
                 Asset Value," below for a description of how net asset value
                 is calculated.     
 
                 SYSTEMATIC INVESTMENT PROGRAMS
                 The Funds offer you several opportunities to capture the
                 benefits of "dollar cost averaging" through systematic
                 investment programs. In a regularly followed dollar cost
                 averaging program, you would purchase more shares when Fund
                 share prices are lower and fewer shares when Fund share
                 prices are higher, so that the average price paid for Fund
                 shares is less than the average price of Fund shares over the
                 same time

                 period. Dollar cost averaging does not assure profits or
                 protect against losses in a steadily declining market. Since
                 dollar cost averaging involves continuous investment
                 regardless of fluctuating price levels, you should consider
                 your financial ability to continue investing in declining as
                 well as rising markets before deciding to invest in this way.
                 The chart below shows the cumulative effect that compound
                 interest can have on a systematic investment program.

                 In the above example, it is assumed that $100 is added to an
                 investment account every month for 20 years. From the same
                 $1,000 beginning, the chart shows the amount that would be in
                 the account after 20 years, assuming no interest and interest
                 compounded annually at the rates of 4%, 5% and 6%.     
                    
                 This chart is designed to illustrate the effects of compound
                 interest, and is not intended to predict the results of an
                 actual investment in a Fund. There are several important
                 differences between the Funds and the hypothetical investment
                 program shown. This example assumes no gain or loss in the
                 net asset value of the investment over the entire 20-year
                 period, whereas the net asset value of each of the Funds will
                 rise and fall due to market conditions or other factors,
                 which could have a significant impact on the total value of
                 your investment. Similarly, this example shows four steady
                 interest rates over the entire 20-year period, whereas the
                 dividend rates of the Funds can be expected to fluctuate over
                 time. The Funds may provide additional information to
                 investors and advisers illustrating the benefits of
                 systematic investment programs and dollar cost averaging.

                 you may make regular investments in an amount of $25 or more
                 each month by authorizing SSI to draw preauthorized checks on

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

                 OTHER SHAREHOLDER PROGRAMS
                 
    
   
Exchange         You may exchange shares of a class of any Fund for shares of
Privilege        the same or equivalent class of another Nuveen Mutual Fund
                 with reciprocal exchange privileges, at net asset value
                 without a sales charge, by sending a written request to the
                 applicable Fund, c/o Shareholder Services, Inc., P.O. Box
                 5330, Denver, CO 80217-5330. Similarly, Class A Shares, Class
                 C Shares and Class R Shares of another Nuveen Mutual Fund
                 purchased subject to a sales charge may be exchanged for the
                 same class of shares of any Fund at net asset value without a
                 sales charge. Exchanges of shares from any Nuveen money
                 market fund will be made into Class A Shares, Class C Shares
                 or Class R Shares of any Fund at the public offering price,
                 which includes an up-front sales charge in the case of Class
                 A Shares. If, however, a sales charge has previously been
                 paid on the investment represented by the exchanged shares
                 (i.e., the shares to be exchanged originally were issued in
                 exchange for shares on which a sales charge was paid), the
                 exchange of shares from a Nuveen money market fund will be
                 made into Class A Shares at net asset value without any up-
                 front sales charge. Shares of any class of a Fund may be
                 exchanged for shares of any Nuveen money market fund. [/R]
                           
                 No CDSC will be charged on the exchange of Class C Shares of
                 any Fund for Class C Shares of any other Nuveen Mutual fund
                 or shares of any Nuveen money market fund. The 12 month
                 holding period for purposes of the CDSC applicable to Class C
                 Shares will continue to run during any period in which Class
                 C Shares of the Fund, Class C Shares of any other Nuveen
                 Mutual Fund or shares of a Nuveen money market fund are held.
                        
                 The shares to be purchased must be offered in your state of
                 residence and you must have held the shares you are
                 exchanging for at least 15 days. The total value of exchanged
                 shares must at least equal the minimum investment requirement
                 of the Nuveen Mutual Fund being purchased. For federal income
                 tax purposes, any exchange constitutes a sale and purchase of
                 shares and may result in capital gain or loss. Before making
                 any exchange, you should obtain the Prospectus for the Nuveen
                 Mutual Fund you are purchasing and read it carefully. If the
                 registration of the account for the Fund you are purchasing
                 is not exactly the same as that of the fund account from
                 which the exchange is made, written instructions from all
                 holders of the account from which the exchange is being made
                 must be received, with signatures guaranteed by a member of
                 an approved Medallion Guarantee Program or in such other
                 manner as may be acceptable to the Fund. You may also
                 exchange shares by telephone if you authorize telephone
                 exchanges by checking the applicable box on the enclosed
                 Application Form or by calling Nuveen toll-free at

                 800.621.7227 to obtain an authorization form. The exchange
                 privilege may be modified or discontinued by any Fund at any
                 time upon prior written notice to shareholders of that Fund.
                    
                 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
                 $1,000 or you already own Class A Shares of that Fund.     
                    
                 The exchange privilege is not intended to permit the Funds to
                 be used as vehicles for short-term trading. Excessive
                 exchange activity may interfere with portfolio management,
                 raise expenses, and otherwise have an adverse effect on all
                 shareholders. In order to limit excessive exchange activity
                 and in other circumstances where Fund management believes
                 doing so would be in the best interest of a Fund, the Funds
                 reserve the right to revise or terminate the exchange
                 privilege, or limit the amount or number of exchanges or
                 reject any exchange. Shareholders would be notified of any
                 such action to the extent required by law.     
                 
    
   
Reinstatement    If you have redeemed Class A Shares of the Funds or Class A
Privilege        Shares of any other Nuveen Mutual Fund that were subject to a
                 sales charge or a CDSC, you have up to one year to reinvest
                 all or part of the full amount of the redemption in the same
                 class of shares of the Fund at net asset value. This
                 reinvestment privilege can be exercised only once for any
                 redemption, and reinvestment will be made at the net asset
                 value of the appropriate class of Fund shares next calculated
                 after reinstatement. If you reinstate shares that were
                 subject to a CDSC, your holding period as of the redemption
                 date will also be reinstated. The tax consequences of any
                 capital gain realized on a redemption will not be affected by
                 reinstatement, but a capital loss may be disallowed in whole
                 or in part depending on the timing and amount of the
                 reinvestment. [/R]

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

                 Exchange Commission, Nuveen Insured Tax-Free Bond Fund, Inc.
                 reserves the right to suspend the continuous offering of
                 shares of any of its Funds at any time, but no suspension
                 shall affect your right of redemption as described below.

DISTRIBUTION AND SERVICE PLAN       NUVEEN TAX-FREE MUTUAL FUNDS PROSPECTUS [/R]
                                                                  
                                                               JULY 1, 1996     
                 Each Fund has adopted a plan (the "Plan") pursuant to Rule
                 12b-1 under the Investment Company Act of 1940, which
                 provides that Class C Shares will be subject to an annual
                 distribution fee, and that both Class A Shares and Class C
                 Shares will be subject to an annual service fee. Class R
                 Shares will not be subject to either distribution or service
                 fees.
                    
                 The distribution fee applicable to Class C Shares under each
                 Fund's Plan will be payable to reimburse Nuveen for services
                 and expenses incurred in connection with the distribution of
                 Class C Shares. The distribution fee primarily reimburses
                 Nuveen for providing compensation to Authorized Dealers,
                 including Nuveen, either at the time of sale or on an ongoing
                 basis. The other expenses for which Nuveen may be reimbursed
                 include, without limitation, expenses of printing and
                 distributing prospectuses to persons other than shareholders
                 of the Fund, expenses of preparing, printing and distributing
                 advertising and sales literature and reports to shareholders
                 used in connection with the sale of Class C Shares, certain
                 other expenses associated with the distribution of Class C
                 Shares, and any other distribution-related expenses that may
                 be authorized from time to time by the Board of Directors.
                        
                 The service fee applicable to Class A Shares and Class C
                 Shares under each Fund's Plan will be payable to Nuveen, to
                 be used to compensate Authorized Dealers, including Nuveen,
                 in connection with the provision of ongoing account services
                 to shareholders. These services may include establishing and
                 maintaining shareholder accounts, answering shareholder
                 inquiries and providing other personal services to
                 shareholders.     
 
                 Each Fund may spend up to .25 of 1% per year of the average
                 daily net assets of Class A Shares as a service fee under the
                 Plan applicable to Class A Shares. Each Fund may spend up to
                 .75 of 1% per year of the average daily net assets of Class C
                 Shares less the amount of any CDSC received by Nuveen as to
                 which no reinstatement privilege has been exercised, as a
                 distribution fee and up to .25 of 1% per year of the average
                 daily net assets of Class C Shares as a service fee under the
                 Plan applicable to Class C Shares.

HOW TO REDEEM FUND SHARES
                    
                 You may require a Fund at any time to redeem for cash your
                 shares of that Fund. All shares will be redeemed at the net
                 asset value next computed after instructions and required
                 documents and certificates, if any, are received in proper
                 form, as described below. However, with respect to certain
                 Class A and Class C shares, as further described below, any
                 applicable contingent deferred sales charge will be deducted
                 from the proceeds of the redemption. There is no charge for
                 redemption of Class R Shares.     
                 
    
   
Contingent       Class A Shares are normally redeemed at net asset value,
Deferred Sales   without any CDSC. However, in the case of Class A Shares
Charge           purchased at net asset value because the purchase amount
                 exceeded $1 million, where the Authorized Dealer did not
                 waive the sales commission, a CDSC of 1% is imposed on any
                 redemption within 18 months of purchase. 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. See "How to Buy
                 Fund Shares." The CDSC will be the lower of (i) the net asset
                 value of shares at the time of purchase or (ii) the net asset
                 value of shares at the time of redemption. [/R]
                    
                 In determining whether a CDSC is payable, a Fund will first
                 redeem shares not subject to any charge, and then in the
                 reverse order in which the shares were purchased, except if
                 another order of redemption would result in a lower charge or
                 you specify another order. No CDSC is charged on shares
                 purchased as a result of automatic reinvestment of dividends
                 or capital gains paid. In addition, no CDSC will be charged
                 on exchanges of shares into another Nuveen Mutual Fund or
                 money market fund. Your holding period is calculated on a
                 monthly basis and begins the first day of the month in which
                 the order for investment is received. The CDSC is calculated
                 based on the lower of the redeemed shares' cost or net asset
                 value at the time of the redemption and is deducted from the
                 redemption proceeds. Nuveen receives the amount of any CDSC
                 you pay on Class A Shares. The CDSC may be waived under
                 certain special circumstances, as described in the Statement
                 of Additional Information.

                 proceeds will be mailed to you within seven days after
                 receipt of your redemption request. For accounts registered
                 in the name of a broker-dealer, payment will be forwarded
                 within three business days. However, if any shares to be
                 redeemed were purchased by check within 15 days prior to the
                 date the redemption request is received, a Fund will not mail
                 the redemption proceeds until the check received for the
                 purchase of shares has cleared, which may take up to 15 days.

                 prior to 4:00 p.m. Eastern Time, the redemption check will
                 normally be mailed the next business day. For requests

                 held in non-certificate form that are worth at least $1,000.
                 You may make TEL-A-WIRE redemption requests by calling Nuveen
                 at 800.621.7227. If a redemption request is received by 4:00
                 p.m. Eastern Time, the shares redeemed will earn income
                 through the day the request is made and the redemption will
                 be made as of 4:00 p.m. that day. If the redemption request
                 is received after 4:00 p.m. Eastern Time, the redemption will
                 be effected at 4:00 p.m. the following business day and the
                 shares redeemed earn income through that day. Redemption
                 proceeds will normally be wired on the second business day
                 following the redemption, but may be delayed one additional
                 business day if the Federal Reserve Bank of Boston or the
                 Federal Reserve Bank of New York is closed on the day
                 redemption proceeds would ordinarily be wired. The Funds
                 reserve the right to charge a fee for TEL-A-WIRE. Proceeds of
                 redemptions through Fund Direct will normally be wired to
                 your Fund Direct bank account on the second or third business
                 day after the redemption. [/R]

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

                                                               JULY 1, 1996     
                 If you own Fund shares currently worth at least $10,000, you
Automatic        may establish an Automatic Withdrawal Plan by completing an
Withdrawal       application form for the Plan. You may obtain an application
Plan             form by checking the applicable box on the enclosed
                 Application Form or by calling Nuveen toll-free at
                 800.621.7227.
 
                 The Plan permits you to request periodic withdrawals on a
                 monthly, quarterly, semi-annual or annual basis in an amount
                 of $50 or more. Depending upon the size of the withdrawals
                 requested under the Plan and fluctuations in the net asset
                 value of Fund shares, these withdrawals may reduce or even
                 exhaust your account.
                    
                 The purchase of Class A Shares, other than through
                 reinvestment, while you are participating in the Automatic
                 Withdrawal Plan with respect to Class A Shares will usually
                 be disadvantageous because you will be paying a sales charge
                 on any Class A Shares you purchase at the same time you are
                 redeeming shares. Similarly, use of the Automatic Withdrawal
                 Plan for Class C Shares held less than 12 months or certain
                 Class A Shares held less than 18 months may be
                 disadvantageous because the newly-purchased Shares may be
                 subject to the 1% CDSC.     
 
                 Each Fund may suspend the right of redemption of Fund shares
General          or delay payment more than seven days (a) during any period
                 when the New York Stock Exchange is closed (other than
                 customary weekend and holiday closings), (b) when trading in
                 the markets the Fund normally utilizes is restricted, or an
                 emergency exists as determined by the Securities and Exchange
                 Commission so that trading of the Fund's investments or
                 determination of its net asset value is not reasonably
                 practicable, or (c) for any other periods that the Securities
                 and Exchange Commission by order may permit for protection of
                 Fund shareholders.
 
                 Each Fund may, from time to time, establish a minimum total
                 investment for Fund shareholders, and each Fund reserves the
                 right to redeem your shares if your investment is less than
                 the minimum after giving you at least 30 days' notice. If any
                 minimum total investment is established, and if your account
                 is below the minimum, you will be allowed 30 days following
                 the notice in which to purchase sufficient shares to meet the
                 minimum. So long as a Fund continues to offer shares at net
                 asset value to holders of Nuveen UITs who are investing their
                 Nuveen UIT distributions, no minimum total investment will be
                 established for that Fund.

                 allocated in proportion to the net assets of each Fund. In

                 distribution or service fees) in any fiscal year from
                 exceeding .975 of 1% of the average daily net asset value of
                 any class of shares of each Fund, Nuveen Advisory has agreed
                 to waive all or a portion of its management fees or reimburse
                 certain expenses of each Fund. Nuveen Advisory may also
                 voluntarily agree to reimburse additional expenses from time
                 to time, which voluntary reimbursements may be terminated at
                 any time in its discretion. For information regarding the
                 management fees and total operating expenses of each class of
                 shares of each of the Funds for the year ended February 29,

                 Overall portfolio management strategy for the Funds is
Portfolio        determined by Nuveen Advisory under the general supervision
Management       and direction of Thomas C. Spalding, Jr., a Vice President of
                 the Nuveen Advisory and of the Funds. Mr. Spalding has been
                 employed by Nuveen since 1976 and by Nuveen Advisory since
                 1978 and has responsibility with respect to the portfolio
                 management of all Nuveen open-end and exchange-traded funds
                 managed by Nuveen Advisory. See the Statement of Additional
                 Information for further information about Mr. Spalding.
                    
                 The day-to-day management of the National Fund is the
                 responsibility of Steven J. Krupa, a Vice President of Nuveen
                 Advisory since October 1990. He currently manages eight
                 Nuveen-sponsored investment companies.

                 The day-to-day management of the Massachusetts Fund is the
                 responsibility of Stephen S. Peterson, an Assistant Portfolio
                 Manager of Nuveen Advisory since October 1991 and portfolio
                 manager of the Massachusetts Fund since May 1993. Prior to
                 joining Nuveen Advisory, he was an analyst in Nuveen's
                 Research Department. Mr. Peterson currently manages nine
                 Nuveen-sponsored investment companies.     
                    
                 The day-to-day management of the New York Fund is the
                 responsibility of Daniel S. Solender, an Assistant Portfolio
                 Manager of Nuveen Advisory since January 1992 and portfolio
                 manager for the New York Fund since September 1994. Prior to
                 joining Nuveen Advisory, Mr. Solender attended the University
                 of Chicago (from September 1990 to June 1992) where he
                 received his M.B.A. and worked part time in the Research
                 Department of Nuveen. He currently manages nine Nuveen-
                 sponsored investment companies.     
                    
                 Consistent with the Funds' investment objective, the day-to-
                 day management of each Fund is characterized by an emphasis
                 on value investing, a process which involves the search for
                 Municipal Obligations with favorable characteristics that, in
                 Nuveen Advisory's judgment, have not yet been recognized in
                 the marketplace. The process of searching for such
                 undervalued or underrated securities is an ongoing one that
                 draws upon the resources of the portfolio managers of the
                 various Nuveen funds and senior management of Nuveen
                 Advisory. All portfolio management decisions are subject to
                 weekly review by Nuveen Advisory's management and to
                 quarterly review by the Board of Directors of Nuveen Insured
                 Tax-Free Bond Fund, Inc.

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

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

                 Any given performance quotation or performance comparison for
General          a Fund is based on historical earnings and should not be
                 considered as representative of the performance of the Fund
                 for any future period. See the Statement of Additional
                 Information for further information concerning the Funds'
                 performance. For information as to current yield and other
                 performance information regarding the Funds, call Nuveen

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

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

                                                               JULY 1, 1996     
                 legislative or administrative action, and any changes may be
                 applied retroactively. Because the Funds' taxes are a complex
                 matter, you should consult your tax adviser for more detailed
                 information concerning the taxation of the Funds and the
                 federal, state and local tax consequences to Fund
                 shareholders.
 
                 Each Fund intends to qualify, as it has in prior years, under
Federal Income   Subchapter M of the Internal Revenue Code of 1986, as amended
Tax:             (the "Code") for tax treatment as a regulated investment
                 company. In order to qualify for treatment as a regulated
Income           investment company, a Fund must satisfy certain requirements
dividends are    relating to the sources of its income, diversification of its
free from        assets and distribution of its income to shareholders. As a
regular          regulated investment company, a Fund will not be subject to
federal income   federal income tax on the portion of its net investment
tax              income and net realized capital gains that is currently
                 distributed to shareholders. Each Fund also intends to
                 satisfy conditions that will enable it to pay "exempt-
                 interest dividends" to its shareholders. This means that you
                 will not be subject to regular federal income tax on Fund
                 dividends you receive from income on Municipal Obligations.
 
                 Your share of a Fund's taxable income, if any, from income on
                 taxable temporary investments and net short-term capital
                 gains, will be taxable to you as ordinary income. If 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 ordinary
                 income to the extent such gain does not exceed the market
                 discount, and any gain realized in excess of the market
                 discount will be treated as capital gains. Distributions, if
                 any, of net long-term capital gains are taxable as long-term
                 capital gains, regardless of the length of time you have
                 owned shares of a Fund. You are required to pay tax on all
                 taxable distributions even if these distributions are
                 automatically reinvested in additional Fund shares. Certain
                 distributions paid by a Fund in January of a given year may
                 be taxable to shareholders as if received the prior December
                 31. As long as a Fund qualifies as a regulated investment
                 company under the Code, distributions will not qualify for
                 the dividends received deduction for corporate shareholders.
                 Investors should consider the tax implications of buying
                 shares immediately prior to a distribution. Investors who
                 purchase shares shortly before the record date for a
                 distribution will pay a per share price that includes the
                 value of the anticipated distribution and will be taxed on
                 the distribution (unless it is exempt from tax) even though
                 the distribution represents a return of a portion of the
                 purchase price.
 
                 If in any year 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
 
                                         53
<PAGE>
 
                 income tax upon its taxable income for that year, and the
                 entire amount of your distributions would be taxable as
                 ordinary income.
 
                 The Code does not permit you to deduct the interest on
                 borrowed monies used to purchase or carry tax-free
                 investments, such as shares of a Fund. Under Internal Revenue
                 Service rules, the purchase of Fund shares may be considered
                 to have been made with borrowed monies even though those
                 monies are not directly traceable to the purchase of those
                 shares.
 
                 Because the net asset value of each Fund's shares includes
                 net tax-exempt interest earned by the Fund but not yet
                 declared as an exempt-interest dividend, each time an exempt-
                 interest dividend is declared, the net asset value of the
                 Fund's shares will decrease in an amount equal to the amount
                 of the dividend. Accordingly, if you redeem shares of a Fund
                 immediately prior to or on the record date of a monthly
                 exempt-interest dividend, you may realize a taxable gain even
                 though a portion of the redemption proceeds may represent
                 your pro rata share of undistributed tax-exempt interest
                 earned by the Fund.
 
                 The redemption or exchange of Fund shares normally will
                 result in capital gain or loss to shareholders. Any loss you
                 may realize on the redemption or exchange of shares of a Fund
                 held for six months or less will be disallowed to the extent
                 of any distribution of exempt-interest dividends received on
                 these shares and will be treated as a long-term capital loss
                 to the extent of any distribution of long-term capital gain
                 received on these shares.
 
                 If you receive social security or railroad retirement
                 benefits you should note that tax-exempt income is taken into
                 account in calculating the amount of these benefits that may
                 be subject to federal income tax.
 
                 The Funds may invest in private activity bonds, the interest
                 on which is not exempt from federal income tax to
                 "substantial users" of the facilities financed by these bonds
                 or "related persons" of such substantial users. Therefore,
                 the Funds may not be appropriate investments for you if you
                 are considered either a substantial user or a related person.
 
                 Each Fund may invest up to 20% of its net assets in AMT
                 Bonds, the interest on which is a specific tax preference
                 item for purposes of computing the alternative minimum tax on
                 corporations and individuals. However, the National Fund to
                 date has not invested in AMT Bonds and has no present
                 intention of doing so. If your tax

                 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 Fund that
                 would otherwise be tax exempt, is included in calculating a
                 corporation's adjusted current earnings.
 
                 Each Fund is required in certain circumstances to withhold
                 31% of taxable dividends and certain other payments paid to
                 non-corporate holders of shares who have not furnished to the
                 Fund their correct taxpayer identification number (in the
                 case of individuals, their social security number) and
                 certain certifications, or who are otherwise subject to back-
                 up withholding.
 
                 Each January, your Fund will notify you of the amount and tax
                 status of Fund distributions for the preceding year.

NET ASSET VALUE
                 
    
   
Net asset        Net asset value of the shares of a Fund will be determined
value is         separately for each class of shares. The net asset value per
calculated       share of a class of shares will be computed by dividing the
daily            value of a Fund's assets attributable to the class, less the
                 liabilities attributable to the class, by the total number of
                 shares of the class outstanding. The net asset value per
                 share is expected to vary among a Fund's Class A Shares,
                 Class C Shares and Class R Shares, principally due to the
                 differences in sales charges, distribution and service fees
                 and other class expenses borne by each class. [/R]
                    
                 Net asset value of the shares of each Fund will be determined
                 by The Chase Manhattan Bank, N.A., the Funds' custodian, as
                 of 4:00 p.m. Eastern Time on each day the New York Stock
                 Exchange is normally open for trading. In determining the net
                 asset value, the custodian uses the valuations of portfolio
                 securities furnished by a pricing service approved by the
                 Board of Directors. The pricing service values portfolio
                 securities at the mean between the quoted bid and asked
                 prices or the yield equivalent when quotations are readily
                 available. Securities for which quotations are not readily
                 available (which are expected to constitute a majority of the
                 securities held by the Funds) are valued at fair value as
                 determined by the pricing service using methods that include
                 consideration of the following: yields or prices of municipal
                 bonds of comparable quality, type of issue, coupon, maturity
                 and rating; indications as to value from securities dealers;
                 and general market conditions. The pricing service may employ
                 electronic data processing techniques and/or a matrix system
                 to determine valuations. The procedures of the pricing
                 service and its valuations are reviewed by the officers of
                 Nuveen Insured Tax-Free Bond Fund, Inc. under the general
                 supervision of its Board of Directors.

                 class expenses, including different distribution and service
                 fees, and each has exclusive voting rights with respect to
                 any distribution or service plan applicable to its shares.
                 There are no conversion, preemptive or other subscription

APPENDIX A--SPECIAL STATE FACTORS AND STATE TAX TREATMENT
       
                 SPECIAL FACTORS PERTAINING TO EACH FUND
                 The following information is a brief summary of special
                 factors that affect the risk of investing in Municipal
                 Obligations issued within the states of Massachusetts and New
                 York. This information was obtained from official statements
                 of issuers located in these states as well as from other
                 publicly available official documents and statements and is
                 not intended to be a complete description. The Funds have not
                 independently verified any of the information contained in
                 these statements and documents. See the Statement of
                 Additional Information for further information relating to
                 current political, economic or regulatory risk factors as
                 well as information relating to legal proceedings which may
                 adversely affect a state's financial position.
 
                 MASSACHUSETTS
                    
                 In recent years, the Commonwealth of Massachusetts and
                 certain of its public bodies and municipalities, particularly
                 the City of Boston, have faced serious financial difficulties
                 which have affected the credit standing and borrowing
                 abilities of Massachusetts and these respective entities and
                 may have contributed to higher interest rates on debt
                 obligations. As a result of these difficulties, the rating
                 agencies lowered the credit ratings on Massachusetts general
                 obligation bonds several times during 1989 and 1990. Since
                 then, both S&P and Moody's have upgraded Massachusetts
                 general obligation bonds several times. As of the date of
                 this Prospectus, the uninsured general obligation bonds carry
                 a rating of A+ by S&P and A1 by Moody's. Since 1988, there
                 has been a significant slowdown in the Commonwealth's
                 economy, as indicated by a rise in unemployment, a slowing of
                 its per capita income growth and a trend in declining state
                 revenues. In fiscal 1991, the Commonwealth's expenditures for
                 state government programs exceeded current revenues, and
                 although fiscal 1992, 1993, 1994 and 1995 results indicate
                 that revenues exceeded expenditures, no assurance can be
                 given that lower than expected tax revenues will not resume
                 and continue. The continuation of, or an increase in, the
                 financial difficulties of the Commonwealth and its public
                 bodies and municipalities, or the development of a financial
                 crisis relating to these entities, could result in declines
                 in the market value of, or default on, existing obligations
                 issued by governmental authorities in the state of
                 Massachusetts, including Municipal Obligations held by the
                 Massachusetts Fund. Many factors, in addition to those cited
                 above do or may have a bearing upon the financial condition
                 of the Commonwealth, including social and economic
                 conditions, many of which are not within the control of the
                 Commonwealth.

                                                               JULY 1, 1996     
                 NEW YORK
                 New York State has historically been one of the wealthiest
                 states in the nation. For decades, however, the State's
                 economy has grown more slowly than that of the nation as a
                 whole, gradually eroding the State's relative economic
                 affluence. Statewide, urban centers have experienced
                 significant changes involving migration of the more affluent
                 to the suburbs and an influx of generally less affluent
                 residents. Regionally, the older Northeast cities have
                 suffered because of the relative success that the South and
                 the West have had in attracting people and business. New York
                 City has faced greater competition as other major cities have
                 developed financial and business resources which make them
                 less dependent on the specialized services traditionally
                 available almost exclusively in New York City, which has had
                 an additional negative impact on New York City's recovery.
                 The State has for many years had a very high State and local
                 tax burden relative to other states. The burden of State and
                 local taxation, in combination with the many other causes of
                 regional economic dislocation, has contributed to the
                 decisions of some businesses and individuals to relocate
                 outside, or not locate within, the State.
                    
                 The State's economic growth continues to lag behind the
                 nation's, due in part to a significant retrenchment in the
                 banking and financial services industry, cutbacks in defense
                 spending, and an overbuilt real estate market. The State has
                 projected the rate of economic growth to slow within New York
                 during 1996 reflecting continued moderate expansion of the
                 national economy.     
                    
                 The Governor announced on April 3, 1996 that the State ended
                 its 1995-96 fiscal year with an operating surplus of
                 approximately $445 million. The State Legislature enacted the
                 State's 1995-96 fiscal year budget on June 7, 1995, more than
                 two months after the start of that fiscal year.     
                    
                 As of January 19, 1996, the updated 1995-96 State Financial
                 Plan (the "Plan") projected total general fund receipts and
                 disbursements each of $32.7 billion, representing reductions
                 in receipts and disbursements of $144 million and $103
                 million, respectively, from the amounts set forth in the
                 1995-96 State budget, as adopted by the legislature. The Plan
                 projected a General Fund balance of approximately $172
                 million at the close of the 1995-96 fiscal year.     
                    
                 The Governor issued a proposed State budget for the 1996-97
                 fiscal year on December 15, 1995, which projected a balanced
                 general fund and receipts and disbursements of $31.3 billion
                 and $31.2 billion, respectively. As of June 10, 1996, the
                 State legislature had not yet enacted, nor had the Governor
                 and the legislature reached an agreement on, the budget for
                 the 1996-97 fiscal year commencing on     
 
                                         A-2
<PAGE>
 
       
                    
                 April 1, 1996. Due to continuing uncertainties as to the
                 amount of federal aid and proposed changes to the Medicaid
                 program resulting from the federal budget impasse, the
                 Governor proposed an alternate budget for fiscal year 1996-97
                 to replace over $1 billion of Medicaid reimbursement which
                 might not be forthcoming. The Governor and the State's
                 legislature have agreed on or proposed a series of short-term
                 stopgap spending measures to fund State payrolls and advances
                 to certain municipalities and certain State programs. The
                 delay in the enactment of the budget may negatively affect
                 certain proposed actions and reduce projected savings.     
                    
                 Following enactment of the State's 1995-96 fiscal year
                 budget, New York City adopted a 1996 fiscal year budget in
                 June 1995, which provided for $31.4 billion in spending.
                 However, in January 1996, unexpected budget gaps totalling
                 approximately $760 million for the 1996 fiscal year were
                 identified and the Mayor called for additional spending cuts.
                 On March 1, 1996, Moody's indicated that its Baa1 rating of
                 New York City's general obligation bonds was under review
                 pending adoption of the City's budget for fiscal year 1997.
                 S&P placed the City on negative credit watch in January 1995.
                 On January 30, 1996, the Mayor outlined his proposed $31
                 billion budget for the 1997 fiscal year which included $2.0
                 billion of deficit reduction measures, more than half of
                 which were dependent upon State actions in the 1996 fiscal
                 year. On May 9, 1996, the Mayor issued a substantially
                 revised fiscal year 1997 budget of $32.7 billion that would
                 reduce spending from the prior year and would include $1.1
                 billion in budget cuts affecting City agencies. The revised
                 budget would restore approximately $300 million in tax cuts
                 and seek a four year extension of the surcharge on the City's
                 personal income tax. The Governor and the legislature have
                 not agreed upon the level of State aid to the City during the
                 1997 fiscal year and there can be no assurances that further
                 cuts will not be necessary to close additional budget gaps
                 once a State budget is adopted. In addition, due to the
                 continuing federal government impasse, the City is uncertain
                 as to the level of federal aid it will receive and the impact
                 of changes in federal law upon its operations and tax
                 receipts. If State or Federal aid in later years is less than
                 the levels projected in the Mayor's proposal, projected
                 savings may be negatively impacted and the Mayor may be
                 required to propose significant additional spending
                 reductions or tax increases to balance the City's budget for
                 the 1997 and later fiscal years. If the State, the State
                 Agencies, New York City, other municipalities or school
                 districts were to suffer serious financial difficulties
                 jeopardizing their respective access to the public credit
                 markets, or increasing the risk of a default, the market
                 price of Municipal Obligations issued by such entities could
                 be adversely affected.

                 Absent appropriate legislative relief, the City may also face
                 limitations on its borrowing capacity after 1998 under the
                 State's Constitution that will prevent it from borrowing
                 additional funds, as a result of the decrease in real estate
                 values within the City. The inability to finance capital
                 improvements would increase the City's budget gaps in later
                 years.     
 
                 DESCRIPTION OF STATE TAX TREATMENT
                 The following state tax information applicable to a Fund or
                 its shareholders is based upon the advice of the Fund's
                 special state tax counsel, and represents a summary of
                 certain provisions of each state's tax laws presently in
                 effect. These provisions are subject to change by legislative
                 or administrative action, which may be applied retroactively
                 to Fund transactions. The state tax information below assumes
                 that each Fund qualifies as a regulated investment company
                 for federal income tax purposes under Subchapter M of the
                 Internal Revenue Code of 1986, as amended (the "Code"), and
                 that amounts so designated by each Fund to its shareholders
                 qualify as "exempt-interest dividends" under Section
                 852(b)(5) of the Code. You should consult your own tax
                 adviser for more detailed information concerning state taxes
                 to which you may be subject.
 
                 MASSACHUSETTS
                 Individual shareholders of the Massachusetts Fund who are
                 subject to Massachusetts income taxation will not be required
                 to include that portion of their federally tax-exempt
                 dividends in Massachusetts gross income which the
                 Massachusetts Fund clearly identifies as directly
                 attributable to interest earned on Municipal Obligations
                 issued by governmental authorities in Massachusetts which are
                 specifically exempted from income taxation in Massachusetts,
                 provided such dividends are identified in a timely written
                 notice mailed to shareholders of the Massachusetts Fund, or
                 interest earned on obligations of certain U.S. territories or
                 possessions. Similarly, such shareholders will not be
                 required to include in Massachusetts gross income capital
                 gain dividends designated by the Massachusetts Fund to the
                 extent such dividends are attributable to gains derived from
                 Municipal Obligations issued by Massachusetts governmental
                 authorities and are specifically exempted from income
                 taxation in Massachusetts, provided such dividends are
                 identified in a timely written notice mailed to shareholders
                 of the Massachusetts Fund. Lastly, any dividends of the
                 Massachusetts Fund attributable to interest on U.S.
                 obligations exempt from state taxation and included in
                 Federal gross income will not be included in Massachusetts
                 gross income, provided such dividends are identified in a
                 timely written notice mailed to shareholders of the
                 Massachusetts Fund. Individual shareholders of the
                 Massachusetts Fund will be required to include all remaining
                 dividends in their Massachusetts income.

                 With respect to corporate shareholders of the Massachusetts
                 Fund that are subject to the Massachusetts excise tax,
                 dividends received from the Massachusetts Fund are includable
                 in gross income and generally may not be deducted by
                 corporate shareholders in computing their net income, and the
                 net worth base of an intangible property corporation includes
                 the corporate shareholders' shares in the Massachusetts Fund.
 
                 NEW YORK
                 Individual shareholders of the New York Fund who are subject
                 to New York State or New York City personal income taxation
                 will not be required to include in their New York adjusted
                 gross income that portion of their exempt-interest dividends
                 (as determined for federal income tax purposes) which the New
                 York Fund clearly identifies as directly attributable to
                 interest earned on Municipal Obligations issued by
                 governmental authorities in New York ("New York Municipal
                 Obligations") and which are specifically exempted from
                 personal income taxation in New York State or New York City,
                 or interest earned on obligations of U.S. territories or
                 possessions that is exempt from taxation by the states
                 pursuant to federal law. Distributions to individual
                 shareholders of dividends derived from interest that does not
                 qualify as exempt-interest dividends (as determined for
                 federal income tax purposes), distributions of exempt-
                 interest dividends (as determined for federal income tax
                 purposes) which are derived from interest on Municipal
                 Obligations issued by governmental authorities in states
                 other than New York State, and distributions derived from
                 interest earned on federal obligations will be included in
                 their New York adjusted gross income as ordinary income.
                 Distributions to individual shareholders of the New York Fund
                 of capital gain dividends (as determined for federal income
                 tax purposes) will be included in their New York adjusted
                 gross income as long-term capital gains. Distributions to
                 individual shareholders of the New York Fund of dividends
                 derived from any net income received from taxable temporary
                 investments and any net short-term capital gains realized by
                 the New York Fund will be included in their New York adjusted
                 gross income as ordinary income.
 
                 For purposes of New York State franchise taxation (or New
                 York City general corporation taxation), entire income will
                 include dividends received from the New York Fund (as
                 determined for federal income tax purposes), as well as any
                 gain or loss recognized from an exchange or redemption of
                 shares of the New York Fund that is recognized for federal
                 income tax purposes, and investment capital will include a
                 corporate shareholder's shares of the New York Fund. If a
                 shareholder of the New York Fund is subject to the New York
                 City unincorporated business tax,

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

                 *Dollar amounts in the table reflect a 36.0% combined federal
                 and state tax rate.     
                    
                 **The table also reflects the New York State supplemental
                 income tax based upon a taxpayer's New York State taxable
                 income and New York State adjusted gross income. This
                 supplemental tax results in an increased marginal state
                 income tax rate to the extent a taxpayer's New York State
                 adjusted gross income ranges between $100,000 and $150,000.
                 Although the table does reflect the effect of the state
                 limitation on itemized deductions that corresponds to the
                 federal limitation, it does not reflect additional
                 limitations under which a New York taxpayer could lose up to
                 an additional 50 percent of his otherwise allowable itemized
                 deductions, because the effect of this limitation varies
                 according to the particular amount of his itemized
                 deductions. The application of this limit may result in a
                 higher tax rate than indicated in the table for joint
                 taxpayers with a New York adjusted gross income of $150,000
                 to $200,000 or $475,000 to $525,000 or single taxpayers with
                 a New York adjusted gross income of $100,000 to $150,000 or
                 $475,000 to $525,000. The table assumes that a taxpayer's New
                 York adjusted gross income equals his federal adjusted gross
                 income. The table does not reflect the treatment of various
                 state and city tax credits that could affect the tax rate of
                 particular New York taxpayers.     
 
                 For example, $50,000 in a 6% taxable investment earns the
                 same after-tax return as $38,400 in a 5% tax-free Nuveen
                 investment.

                 *The dollar amounts in the table reflect a 39.5% combined
                 federal, state and New York City tax rate.
                    
                 **The table also reflects the New York State supplemental
                 income tax based upon a taxpayer's New York State taxable
                 income and New York State adjusted gross income. This
                 supplemental tax results in an increased marginal state
                 income tax rate to the extent a taxpayer's New York State
                 adjusted gross income ranges between $100,000 and $150,000.
                 Although the table does reflect the effect of the state
                 limitation on itemized deductions that corresponds to the
                 federal limitation, it does not reflect additional
                 limitations under which a New York taxpayer could lose up to
                 an additional 50 percent of his otherwise allowable itemized
                 decutions, because the effect of this limitation varies
                 according to the particular amount of his itemized
                 deductions. The application of this limit may result in a
                 higher tax rate than indicated in the table for joint
                 taxpayers with a New York adjusted gross income of $150,000
                 to $200,000 or $475,000 to $525,000 or single taxpayers with
                 a New York adjusted gross income of $100,000 to $150,000 or
                 $475,000 to $525,000. The table assumes that a taxpayer's New
                 York adjusted gross income equals his federal adjusted gross
                 income. The table does not reflect the treatment of various
                 state and city tax credits that could affect the tax rate of
                 particular New York taxpayers.     
 
                 For example, $50,000 in a 6% taxable investment earns the
                 same after-tax return as $36,300 in a 5% tax-free Nuveen
                 investment.

                 FUNDAMENTAL POLICIES AND INVESTMENT PORTFOLIO
 
FUNDAMENTAL POLICIES
The investment objective and certain fundamental investment policies of each
Fund are described in the Prospectus. Each of the Funds, as a fundamental poli-
cy, 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 temporary invest-
ments, as those terms are defined in the Prospectus;
   
(2) Invest more than 5% of its total assets in securities of any one issuer,
except that this limitation shall not apply to securities of the United States
Government, its agencies and instrumentalities or to the investment of 25% of
such Fund's assets;     
 
(3) Borrow money, except from banks for temporary or emergency purposes and not
for investment purposes and then only in an amount not exceeding (a) 10% of the
value of its total assets at the time of borrowing or (b) one-third of the
value of the Fund's total assets including the amount borrowed, in order to
meet redemption requests which might otherwise require the untimely disposition
of securities. While any such borrowings exceed 5% of such Fund's total assets,
no additional purchases of investment securities will be made by such Fund. If
due to market fluctuations or other reasons, the value of the Fund's assets
falls below 300% of its borrowings, the Fund will reduce its borrowings within
3 business days. To do this, the Fund may have to sell a portion of its invest-
ments 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 (3) 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
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 in-
vesting 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 State-
ment 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;
 
2
<PAGE>
 
(10) Make short sales of securities or purchase any securities on margin, ex-
cept for such short-term credits as are necessary for the clearance of transac-
tions;
 
(11) Write or purchase put or call options, except to the extent that the pur-
chase of a stand-by commitment may be considered the purchase of a put, and ex-
cept for transactions involving options within the limits described in the Pro-
spectus and this Statement of Additional Information;
 
(12) Invest more than 5% of its total assets in securities of unseasoned is-
suers which, together with their predecessors, have been in operation for less
than three years;
 
(13) Invest more than 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;
 
(14) Invest more than 10% of its total assets in repurchase agreements maturing
in more than seven days, "illiquid" securities (such as non-negotiable CDs) and
securities without readily available market quotations;
 
(15) Purchase or retain the securities of any issuer other than the securities
of the Fund if, to the Fund's knowledge, those directors of Nuveen Insured Tax-
Free Bond Fund, Inc., 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.
 
For the purpose of applying the limitations set forth in paragraphs (2) and
(12) above, an issuer shall be deemed the sole issuer of a security when its
assets and revenues are separate from other governmental entities and its secu-
rities are backed only by its assets and revenues. Similarly, in the case of a
non-governmental user, such as an industrial corporation or a privately owned
or operated hospital, if the security is backed only by the assets and revenues
of the non-governmental user, then such non-governmental user would be deemed
to be the sole issuer. Where a security is also backed by the enforceable obli-
gation of a superior or unrelated governmental entity or other entity (other
than a bond insurer), it shall also be included in the computation of securi-
ties owned that are issued by such governmental or other entity.
 
Where a security is guaranteed by a governmental entity or some other facility,
such as a bank guarantee or letter of credit, such a guarantee or letter of
credit would be considered a separate security and would be treated as an issue
of such government, other entity or bank. Where a security is insured by bond
insurance, it shall not be considered a security issued or guaranteed by the
insurer; instead the issuer of such security will be determined in accordance
with the principles set forth above. The foregoing restrictions do not limit
the percentage of a Fund's assets that may be invested in securities insured by
any single insurer. It is a fundamental policy of each Fund, which cannot be
changed without the approval of the holders of a majority of shares of such
Fund, that a Fund will not hold securities of a single bank, including securi-
ties backed by a letter of credit of such bank, if such holdings would exceed
10% of the total assets of such Fund.
 
                                                                               3
<PAGE>
 
The foregoing restrictions and limitations, as well as the Funds' 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 re-
sult 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 Invest-
ment 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.
 
Nuveen Insured Tax-Free Bond Fund, Inc. is a series company under SEC Rule
18f-2 and each Fund is a separate series issuing its own shares. Nuveen In-
sured Tax-Free Bond Fund, Inc. currently has three authorized series: the
Nuveen Insured Municipal Bond Fund (the "National Fund"), the Nuveen Massachu-
setts Insured Tax-Free Value Fund (the "Massachusetts Fund") and the Nuveen
New York Insured Tax-Free Value Fund (the "New York Fund"). 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 series affected by
such matter.
 
PORTFOLIO SECURITIES
As described in the Prospectus, each Fund invests primarily in a diversified
portfolio of Municipal Obligations. In the case of the Massachusetts Fund and
the New York Fund, the Municipal Obligations are issued within their respec-
tive states or certain U.S. possessions and territories and, in the case of
the National Fund, the Municipal Obligations are issued within the 50 states
and certain U.S. possessions and territories. In general, Municipal Obliga-
tions 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. In-
dustrial 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. Municipal Obligations in which the
Massachusetts Fund and the New York Fund will primarily invest are issued by
that Fund's respective state and cities and local authorities in that state,
and bear interest that, in the opinion of bond counsel to the issuer, is ex-
empt from federal income tax and from personal income tax imposed by the re-
spective state. The National Fund will primarily invest in Municipal Obliga-
tions that are issued by governmental authorities within the 50 states and
certain U.S. possessions or territories, and bear interest which in the opin-
ion of bond counsel to the issuer, is exempt from federal income tax.
 
Each Fund will, under normal circumstances, invest substantially all (at least
80%) of its net assets in Municipal Obligations which are either covered by
insurance guaranteeing the timely payment of principal and interest thereon or
backed by an escrow or trust account containing sufficient U.S. Government or
U.S. Government agency securities to ensure timely payment of principal and
interest.

<PAGE>
 
Each insured Municipal Obligation held by a Fund will either be (1) covered by
an insurance policy applicable to a specific security and obtained by the is-
suer of the security or a third party at the time of original issuance ("Origi-
nal Issue Insurance"), (2) covered by an insurance policy applicable to a spe-
cific security and obtained by the Fund or a third party subsequent to the time
of original issuance ("Secondary Market Insurance"), or (3) covered by a master
municipal insurance policy purchased by the Fund ("Portfolio Insurance"). Each
Fund currently maintains a policy of Portfolio Insurance with MBIA Insurance
Corporation, AMBAC Indemnity Corporation, Financial Security Assurance, Inc.,
and Financial Guaranty Insurance Company, and may in the future obtain other
policies of Portfolio Insurance, depending on the availability of such policies
on terms favorable to the Fund. However, a Fund may determine not to obtain
such policies and to emphasize investments in Municipal Obligations insured un-
der Original Issue Insurance or Secondary Market Insurance. In any event, a
Fund will only obtain policies of Portfolio Insurance issued by insurers whose
claims-paying ability is rated Aaa by Moody's Investors Service, Inc.
("Moody's") or AAA by Standard & Poor's Corporation ("S&P"). Each Fund cur-
rently intends to obtain insurance policies only from mono-line insurers spe-
cializing in insuring municipal debt. Municipal Obligations covered by Original
Issue Insurance or Secondary Market Insurance are themselves typically assigned
a rating of Aaa or AAA, as the case may be, by virtue of the Aaa or AAA claims-
paying ability of the insurer and would generally be assigned a lower rating if
the rating were based primarily upon the credit characteristics of the issuer
without regard to the insurance feature. By way of contrast, the ratings, if
any, assigned to Municipal Obligations insured under Portfolio Insurance will
be based primarily upon the credit characteristics of the issuers without re-
gard to the insurance feature, and will generally carry a rating that is below
Aaa or AAA. While in the portfolio of a Fund, however, a Municipal Obligation
backed by Portfolio Insurance will effectively be of the same quality as a Mu-
nicipal Obligation issued by an issuer of comparable credit characteristics
that is backed by Original Issue Insurance or Secondary Market Insurance.
 
Each Fund's policy of investing in Municipal Obligations insured by insurers
whose claims-paying ability is rated Aaa or AAA will apply only at the time of
the purchase of a security, and a Fund will not be required to dispose of secu-
rities in the event Moody's or S&P, as the case may be, downgrades its assess-
ment of the claims-paying ability of a particular insurer or the credit charac-
teristics of a particular issuer. In this connection, it should be noted that
in the event Moody's or S&P or both should downgrade its assessment of the
claims-paying ability of a particular insurer, it could also be expected to
downgrade the ratings assigned to Municipal Obligations insured under Original
Issue Insurance or Secondary Market Insurance issued by such insurer, and Mu-
nicipal Obligations insured under Portfolio Insurance issued by such insurer
would also be of reduced quality in the portfolio of a Fund. Moody's and S&P
continually assess the claims-paying ability of insurers and the credit charac-
teristics of issuers, and there can be no assurance that they will not down-
grade their assessments subsequent to the time a Fund purchases securities.
 
In addition to insured Municipal Obligations, a Fund may invest in Municipal
Obligations that are entitled to the benefit of an escrow or trust account
which contains securities issued or guaranteed by the U.S. Government or U.S.
Government agencies, backed by the full faith and credit of the United States,
and sufficient in amount to ensure the payment of interest and principal on the
original interest payment and maturity dates ("collateralized obligations").
These collateralized obligations generally
 
                                                                               5

will not be insured and will include, but are not limited to, Municipal Obli-
gations that have been (1) advance refunded where the proceeds of the re-
funding have been used to purchase U.S. Government or U.S. Government agency
securities that are placed in escrow and whose interest or maturing principal
payments, or both, are sufficient to cover the remaining scheduled debt serv-
ice on the Municipal Obligations, and (2) issued under state or local housing
finance programs which use the issuance proceeds to fund mortgages that are
then exchanged for U.S. Government or U.S. Government agency securities and
deposited with a trustee as security for the Municipal Obligations. These col-
lateralized obligations are normally regarded as having the credit charac-
teristics of the underlying U.S. Government or U.S. Government agency securi-
ties. Collateralized obligations will not constitute more than 20% of each
Fund's assets.
 
Each insured Municipal Obligation in which a Fund invests will be covered by
Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance.
There is no limitation on the percentage of the Fund's assets that may be in-
vested in Municipal Obligations insured by any given insurer.
 
Original Issue Insurance. Original Issue Insurance is purchased with respect
to a particular issue of Municipal Obligations by the issuer thereof or a
third party in conjunction with the original issuance of such Municipal Obli-
gations. Under such insurance, the insurer unconditionally guarantees to the
holder of the Municipal Obligation the timely payment of principal and inter-
est on such obligation when and as such payments shall become due but shall
not be paid by the issuer, except that in the event of any acceleration of the
due date of the principal by reason of mandatory or optional redemption (other
than acceleration by reason of a mandatory sinking fund payment), default or
otherwise, the payments guaranteed may be made in such amounts and at such
times as payments of principal would have been due had there not been such ac-
celeration. The insurer is responsible for such payments less any amounts re-
ceived by the holder from any trustee for the Municipal Obligation issuers or
from any other source. Original Issue Insurance does not guarantee payment on
an accelerated basis, the payment of any redemption premium (except with re-
spect to certain premium payments in the case of certain small issue indus-
trial development and pollution control Municipal Obligations), the value of
the shares of the Fund, the market value of Municipal Obligations, or payments
of any tender purchase price upon the tender of the Municipal Obligations.
Original Issue Insurance also does not insure against nonpayment of principal
of or interest on Municipal Obligations resulting from the insolvency, negli-
gence or any other act or omission of the trustee or other paying agent for
such obligations.
 
In the event that interest on or principal of a Municipal Obligation covered
by insurance is due for payment but is unpaid by the issuer thereof, the ap-
plicable insurer will make payments to its fiscal agent (the "Fiscal Agent")
equal to such unpaid amounts of principal and interest not later than one
business day after the insurer has been notified that such nonpayment has oc-
curred (but not earlier than the date such payment is due). The Fiscal Agent
will disburse to the Fund the amount of principal and interest which is then
due for payment but is unpaid upon receipt by the Fiscal Agent of (i) evidence
of the Fund's right to receive payment of such principal and interest and (ii)
evidence, including any appropriate instruments of assignment, that all of the
rights to payment of such principal or interest then due for payment shall
thereupon vest in the insurer. Upon payment by the insurer of any principal or
interest payments with respect to any Municipal Obligations, the insurer shall
succeed to the rights of the Fund with respect to such payment.

<PAGE>
 
Original Issue Insurance remains in effect as long as the Municipal Obliga-
tions covered thereby remain outstanding and the insurer remains in business,
regardless of whether a Fund ultimately disposes of such Municipal Obliga-
tions. Consequently, Original Issue Insurance may be considered to represent
an element of market value with respect to the Municipal Obligations so in-
sured, but the exact effect, if any, of this insurance on such market value
cannot be estimated.
 
Secondary Market Insurance. Subsequent to the time of original issuance of a
Municipal Obligation, the Fund or a third party may, upon the payment of a
single premium, purchase insurance on such Municipal Obligation. Secondary
Market Insurance generally provides the same type of coverage as is provided
by Original Issue Insurance and remains in effect as long as the Municipal Ob-
ligation covered thereby remain outstanding, the holder of such Municipal Ob-
ligation does not voluntarily relinquish the Secondary Market Insurance and
the insurer remains in business, regardless of whether the Fund ultimately
disposes of such Municipal Obligation.
 
One of the purposes of acquiring Secondary Market Insurance with respect to a
particular Municipal Obligation would be to enable a Fund to enhance the value
of such Municipal Obligation. A Fund, for example, might seek to purchase a
particular Municipal Obligation and obtain Secondary Market Insurance with re-
spect thereto if, in the opinion of Nuveen Advisory, the market value of such
Municipal Obligation, as insured, would exceed the current value of the Munic-
ipal Obligation without insurance plus the cost of the Secondary Market Insur-
ance. Similarly, if a Fund owns but wishes to sell a Municipal Obligation that
is then covered by Portfolio Insurance, the Fund might seek to obtain Second-
ary Market Insurance with respect thereto if, in the opinion of Nuveen Adviso-
ry, the net proceeds of a sale by the Fund of such obligation, as insured,
would exceed the current value of such obligation plus the cost of the Second-
ary Market Insurance.
   
Portfolio Insurance. Portfolio Insurance guarantees the payment of principal
and interest on specified eligible Municipal Obligations purchased by a Fund.
Except as described below, Portfolio Insurance generally provides the same
type of coverage as is provided by Original Issue Insurance or Secondary Mar-
ket Insurance. Municipal Obligations insured under one Portfolio Insurance
policy would generally not be insured under any other policy purchased by the
Fund. A Municipal Obligation is eligible for coverage under a policy if it
meets certain requirements of the insurer. Portfolio Insurance is intended to
reduce financial risk, but the cost thereof and compliance with investment re-
strictions imposed under the policy will reduce the yield to shareholders of a
Fund.     
 
If a Municipal Obligation is already covered by Original Issue Insurance or
Secondary Market Insurance, then such Municipal Obligation is not required to
be additionally insured under any policy of Portfolio Insurance that a Fund
may purchase. All premiums respecting Municipal Obligations covered by Origi-
nal Issue Insurance or Secondary Market Insurance are paid in advance by the
issuer or other party obtaining the insurance.
 
Portfolio Insurance policies are effective only as to Municipal Obligations
owned by and held by a Fund, and do not cover Municipal Obligations for which
the contract for purchase fails. A "when-issued" Municipal Obligation will be
covered under a Portfolio Insurance policy upon the settlement date of the is-
sue of such "when-issued" Municipal Obligation. In determining whether to in-
sure Municipal Obliga-
 
                                                                              7
<PAGE>
 
tions held by a Fund, an insurer will apply its own standards, which correspond
generally to the standards it has established for determining the insurability
of new issues of Municipal Obligations. See "Original Issue Insurance" above.
 
Each Portfolio Insurance policy will be noncancellable and will remain in ef-
fect so long as the Funds are in existence, the Municipal Obligations covered
by the policy continue to be held by the Funds, and the Funds pay the premiums
for the policy. Each insurer will generally reserve the right at any time upon
90 days' written notice to the Funds to refuse to insure any additional securi-
ties purchased by the Funds after the effective date of such notice. The Board
of Directors will generally reserve the right to terminate each policy upon
seven days' written notice to an insurer if it determines that the cost of such
policy is not reasonable in relation to the value of the insurance to a Fund.
 
Each Portfolio Insurance policy will terminate as to any Municipal Obligation
that has been redeemed from or sold by a Fund on the date of such redemption or
the settlement date of such sale, and an insurer shall not have any liability
thereafter under a policy as to any such Municipal Obligation, except that if
the date of such redemption or the settlement date of such sale occurs after a
record date and before the related payment date with respect to any such Munic-
ipal Obligation, the policy will terminate as to such Municipal Obligation on
the business day immediately following such payment date. Each policy will ter-
minate as to all Municipal Obligations covered thereby on the date on which the
last of the covered Municipal Obligations mature, are redeemed or are sold by a
Fund.
 
One or more policies of Portfolio Insurance may provide a Fund, pursuant to an
irrevocable commitment of the insurer, with the option to exercise the right to
obtain permanent insurance ("Permanent Insurance") with respect to a Municipal
Obligation that is to be sold by the Fund. A Fund would exercise the right to
obtain Permanent Insurance upon payment of a single, predetermined insurance
premium payable from the proceeds of the sale of such Municipal Obligation. It
is expected that a Fund will exercise the right to obtain Permanent Insurance
for a Municipal Obligation only if, in the opinion of Nuveen Advisory, upon
such exercise the net proceeds from the sale by the Fund of such obligation, as
insured, would exceed the proceeds from the sale of such obligation without in-
surance.
 
The Permanent Insurance premium with respect to each such obligation is deter-
mined based upon the insurability of each such obligation as of the date of
purchase by a Fund and will not be increased or decreased for any change in the
creditworthiness of such obligation unless such obligation is in default as to
payment of principal or interest, or both. In such event, the Permanent Insur-
ance premium shall be subject to an increase predetermined at the date of pur-
chase by a Fund.
 
The Funds generally intend to retain any insured securities covered by Portfo-
lio Insurance that are in default or in significant risk of default and to
place a value on the insurance, which ordinarily will be the difference between
the market value of the defaulted security and the market value of similar se-
curities of minimum investment grade (i.e., rated BBB) that are not in default.
In certain circumstances, however, Nuveen Advisory may determine that an alter-
native value for the insurance, such as the difference between the market value
of the defaulted security and either its par value or the market value of secu-
rities of a similar nature that are not in default or in significant risk of
default, is more appropriate. To the extent that a Fund holds such defaulted
securities, it may be limited in its ability to manage its
 
8
<PAGE>
 
investment portfolio and to purchase other Municipal Obligations. Except as de-
scribed above with respect to securities covered by Portfolio Insurance that
are in default or subject to significant risk of default, the Funds will not
place any value on the insurance in valuing the Municipal Obligations that it
holds.
 
Because each Portfolio Insurance policy will terminate as to Municipal Obliga-
tions sold by a Fund on the date of sale, in which event the insurer will be
liable only for those payments of principal and interest that are then due and
owing (unless Permanent Insurance is obtained by a Fund), the provision for
this insurance will not enhance the marketability of securities held by a Fund,
whether or not the securities are in default or in significant risk of default.
On the other hand, since Original Issue Insurance and Secondary Market Insur-
ance generally will remain in effect as long as Municipal Obligations covered
thereby are outstanding, such insurance may enhance the marketability of such
securities, even when such securities are in default or in significant risk of
default, but the exact effect, if any, on marketability cannot be estimated.
Accordingly, the Funds may determine to retain or, alternatively, to sell Mu-
nicipal Obligations covered by Original Issue Insurance or Secondary Market In-
surance that are in default or in significant risk of default.
   
Premiums for a Portfolio Insurance policy are paid monthly, and are adjusted
for purchases and sales of Municipal Obligations covered by the policy during
the month. The yield on each of the Funds is reduced to the extent of the in-
surance premiums allocated to it. Depending upon the characteristics of the Mu-
nicipal Obligations held by a Fund, the annual premium rate for policies of
Portfolio Insurance is estimated to range from .15% to .30% of the value of the
Municipal Obligations covered under the policy. Because the majority of the Mu-
nicipal Obligations in each Fund were not covered by policies of Portfolio In-
surance during the year ended February 29, 1996, premium expenses as a percent-
age of the value of Municipal Obligations held by each Fund for such period
were .00%, .01% and .00% for the National Fund, the Massachusetts Fund and the
New York Fund, respectively.     
 
Set forth below is information about the various municipal bond insurers with
whom the Insured Tax-Free Bond Fund, Inc. currently maintains policies of Port-
folio Insurance.

AMBAC Indemnity is a Wisconsin-domiciled stock insurance corporation regulated
by the Office of the Commissioner of Insurance of the State of Wisconsin and
licensed to do business in 50 states, the District of Columbia, the Territory
of Guam and the Commonwealth of Puerto Rico, with admitted assets of approxi-
mately $2,440,000,000 (unaudited) and statutory capital of approximately

a triple-A claims-paying ability rating to AMBAC Indemnity.     
 
AMBAC Indemnity has obtained a ruling from the Internal Revenue Service to the
effect that the insuring of an obligation by AMBAC Indemnity will not affect
the treatment for federal income tax purposes of interest on such obligation
and that insurance proceeds representing maturing interest paid
 
                                                                               9

by AMBAC Indemnity under policy provisions substantially identical to those
contained in its municipal bond insurance policy shall be treated for federal
income tax purposes in the same manner as if such payments were made by the is-
suer of the bonds.

MBIA INSURANCE CORPORATION ("MBIA")
MBIA, formerly known as Municipal Bond Investors Assurance Corporation, is the
principal operating subsidiary of MBIA Inc., A New York Stock Exchange listed
company. MBIA Inc. is not obligated to pay the debts of or claims against MBIA.
MBIA is a limited liability corporation rather than a several liability associ-

ties. Copies of MBIA's year end financial statements prepared in accordance
with statutory accounting practices are available from MBIA. The address of
MBIA is 113 King Street, Armonk, New York 10504.
 
MBIA's policy unconditionally and irrevocably guarantees to the Insured Tax-
Free Bond Fund the full and complete payment required to be made by or on be-
half of the issuer to the applicable paying agent or its successor of an amount
equal to (i) the principal of (either at the stated maturity or by advancement
of maturity pursuant to a mandatory sinking fund payment) and interest on, the
Municipal Obligations as such payments shall become due but shall not be so
paid (except that in the event of any acceleration of the due date of such
principal by reason of mandatory or optional redemption or acceleration result-
ing from default or otherwise, other than any advancement of maturity pursuant
to a mandatory sinking fund payment, the payments guaranteed by MBIA's policy
shall be made in such amounts and at such times as such payments of principal
would have been due had there not been any such acceleration) and (ii) the re-
imbursement of any such payment which is subsequently recovered from the Fund
pursuant to a final judgment by a court of competent jurisdiction that such
payment constitutes an avoidable preference to the Fund within the meaning of
any applicable bankruptcy law (a "Preference").
 
MBIA's policy does not insure against loss of any prepayment premium which may
at any time be payable with respect to any Municipal Obligation. MBIA's policy
does not, under any circumstance, insure against loss relating to: (i) optional
or mandatory redemptions (other than mandatory sinking fund redemptions); (ii)
any payments to be made on an accelerated basis; (iii) payments of the purchase
price of Municipal Obligations upon tender thereof; or (iv) any Preference re-
lating to (i) through (iii) above. MBIA's policy also does not insure against
nonpayment of principal of or interest on the Municipal Obligations resulting
from the insolvency, negligence or any other act or omission of any paying
agent for the Municipal Obligations.
 
With respect to small issue industrial development bonds and pollution control
revenue bonds covered by the policy, MBIA guarantees the full and complete pay-
ments required to be made by or on behalf of an issuer of such bonds if there
occurs pursuant to the terms of the bonds an event which results in the loss of
the tax-exempt status of interest on such bonds, including principal, interest
or premium payments payable thereon, if any, as and when required to be made by
or on behalf of the issuer pursuant to the terms of such bonds.
 
Upon receipt of telephonic or telegraphic notice, such notice subsequently con-
firmed in writing by registered or certified mail, or upon receipt of written
notice by registered or certified mail, by MBIA from the paying agent or the
Fund that a required payment of any insured amount which is then due, that such
required payment has not been made, MBIA on the due date of such payment or
within one business day after receipt of notice of such nonpayment, whichever
is later, will make a deposit of funds, in an account with State Street Bank
and Trust Company, N.A., in New York, New York, or its successor, sufficient
for the payment of any such insured amounts which are then due. Upon present-
ment and surrender of such Municipal Obligations or presentment of such other
proof of ownership of the Municipal Obligations, together with any appropriate
instruments of assignment to evidence the assignment of the insured amounts due
on the Municipal Obligations as are paid by MBIA, and appro-
 
                                                                              11

priate instruments to effect the appointment of MBIA as agent for the Fund in
any legal proceeding related to payment of insured amounts on Municipal Obliga-
tions, such instruments being in a form satisfactory to State Street Bank and
Trust Company, N.A., State Street Bank and Trust Company, N.A. shall disburse
to the Fund or the paying agent payment of the insured amounts due on such Mu-
nicipal Obligations, less any amount held by the paying agent for the payment
of such insured amounts and legally available therefor.
 
FINANCIAL GUARANTY INSURANCE COMPANY ("FINANCIAL GUARANTY")
The Portfolio Insurance Policy is non-cancellable except for failure to pay the
premium. The premium rate for each purchase of a security covered by the Port-
folio Insurance Policy is fixed for the life of the Insured Bond. The insurance
premiums are payable monthly by the Fund and are adjusted for purchases, sales
and payments prior to maturity of Insured Bonds during the month. In the event
of a sale of any Insured Bond by the Fund or payment thereof prior to maturity,
the Portfolio Insurance policy terminates as to such Insured Bond.
 
Under the provisions of the Portfolio Insurance Policy, Financial Guaranty un-
conditionally and irrevocably agrees to pay to State Street Bank and Trust Com-
pany, or its successor, as its agent (the "Fiscal Agent"), that portion of the
principal of and interest on the Insured Bonds which shall become due for pay-
ment but shall be unpaid by reason of nonpayment by the issuer of the Insured
Bonds. The term "due for payment" means, when referring to the principal of an
Insured Bond, its stated maturity date or the date on which it shall have been
called for mandatory sinking fund redemption and does not refer to any earlier
date on which payment is due by reason of call for redemption (other than by
mandatory sinking fund redemption), acceleration or other advancement of matu-
rity and means, when referring to interest on an Insured Bond, the stated date
for payment of interest. In addition, the Portfolio Insurance Policy covers
nonpayment by the issuer that results from any payment of principal or interest
made by such issuer on the Insured Bond to the Fund which has been recovered
from the Fund or its shareholders pursuant to the United States Bankruptcy Code
by a trustee in bankruptcy in accordance with a final, nonappealable order of a
court having competent jurisdiction.
 
Financial Guaranty will make such payments to the Fiscal Agent on the date such
principal or interest becomes due for payment or on the business day next fol-
lowing the day on which Financial Guaranty shall have received notice of non-
payment, whichever is later. The Fiscal Agent will disburse to the Trustee the
face amount of principal and interest which is then due for payment but is un-
paid by reason of nonpayment by the issuer, but only upon receipt by the Fiscal
Agent of (i) evidence of the Trustee's right to receive payment of the princi-
pal or interest due for payment and (ii) evidence, including any appropriate
instruments of assignment, that all of the rights to payment of such principal
or interest due for payment thereupon shall vest in Financial Guaranty. Upon
such disbursement, Financial Guaranty shall become the owner of the Insured
Bond, appurtenant coupon or right to payment of principal or interest on such
Insured Bond and shall be fully subrogated to all of the Trustee's rights
thereunder, including the right to payment, thereof.
 
In determining whether to insure municipal securities held in the Fund, Finan-
cial Guaranty will apply its own standards which are not necessarily the same
as the criteria used in regard to the selection of securities by the Funds.
 
12
<PAGE>
 
Certain of the municipal securities insured under the Portfolio Insurance Pol-
icy may also be insured under an insurance policy obtained by the issuer of
such municipal securities. The premium for any insurance policy or policies
obtained by an issuer or Insured Bonds has been paid in advance by such issuer
and any such policy or policies are non-cancellable and will continue in force
so long as the Insured Bonds so insured are outstanding. Financial Guaranty
has also agreed, if requested by the Funds on or before the fifth day preced-
ing the 1st day of any month, to insure to maturity Insured Bonds sold by the
Trustee during the month immediately following such request of the Funds. The
premium for any such insurance to maturity provided by Financial Guaranty is
paid by the Fund and any such insurance is non-cancellable and will continue
in force so long as the Bonds so insured are outstanding.
   
Financial Guaranty is a wholly-owned subsidiary of FGIC Corporation (the "Cor-
poration"), a Delaware holding company. The Corporation is a subsidiary of
General Electric Capital Corporation. Financial Guaranty is a monoline finan-
cial guaranty insurer domiciled in the State of New York and subject to regu-
lation by the State of New York Insurance Department. As of March 31, 1996,
the total capital and surplus of Financial Guaranty was approximately
$1,032,675,000. Financial Guaranty prepares financial statements on the basis
of both statutory accounting principles and generally accepted accounting
principles. Copies of such financial statements may be obtained by writing to
Financial Guaranty at 115 Broadway, New York, New York 10006, Attention: Com-
munications Department (telephone number: (212) 312-3000) or to the New York
State Insurance Department at 160 West Broadway, 18th Floor, New York, New
York 10013, Attention: Property Companies Bureau (telephone number: (212) 602-
0389).     
 
The policies of insurance obtained by the Funds from Financial Guaranty and
the negotiations in respect thereof represent the only relationship between
Financial Guaranty and the Funds. Otherwise neither Financial Guaranty nor its
parent, FGIC Corporation, or any affiliate thereof has any significant rela-
tionship, direct or indirect, with the Funds or the Board of Directors.
   
The above municipal bond insurers have insurance claims-paying ability ratings
of AAA from S&P and Aaa from Moody's. Financial Guaranty also has an insurance
claims-paying ability rating of AAA from Fitch.     
 
An S&P insurance claims-paying ability rating is an assessment of an operating
insurance company's financial capacity to meet obligations under an insurance
policy in accordance with its terms. An insurer with an insurance claims-pay-
ing ability rating of AAA has the highest rating assigned by S&P. Capacity to
honor insurance contracts is adjudged by S&P to be extremely strong and highly
likely to remain so over a long period of time. A Moody's insurance claims-
paying ability rating is an opinion of the ability of an insurance company to
repay punctually senior policyholder obligations and claims. An insurer with
an insurance claims-paying ability rating of Aaa is adjudged by Moody's to be
of the best quality. In the opinion of Moody's, the policy obligations of an
insurance company with an insurance claims-paying ability rating of Aaa carry
the smallest degree of credit risk and, while the financial strength of these
companies is likely to change, such changes as can be visualized are most un-
likely to impair the company's fundamentally strong position.
 
An insurance claims-paying ability rating by S&P or Moody's does not consti-
tute an opinion on any specific contract in that such an opinion can only be
rendered upon the review of the specific insurance
 
                                                                             13
<PAGE>
 
contract. Furthermore, an insurance claims-paying ability rating does not take
into account deductibles, surrender or cancellation penalties or the timeliness
of payment, nor does it address the ability of a company to meet nonpolicy ob-
ligations (i.e., debt contracts).
 
The assignment of ratings by S&P or Moody's to debt issues that are fully or
partially supported by insurance policies, contracts or guarantees is a sepa-
rate process from the determination of claims-paying ability ratings. The like-
lihood of a timely flow of funds from the insurer to the trustee for the bond-
holders is a key element in the rating determination for such debt issues.
 
S&P's and Moody's ratings are not recommendations to buy, sell or hold the Mu-
nicipal Obligations insured by policies issued by AMBAC Indemnity, Financial
Security, MBIA or Financial Guaranty and such ratings may be subject to revi-
sion or withdrawal at any time by the rating agencies. Any downward revision or
withdrawal of either or both ratings may have an adverse effect on the market
price of the Municipal Obligations insured by policies issued by AMBAC Indemni-
ty, Financial Security, MBIA or Financial Guaranty.
 
S&P's ratings of AMBAC Indemnity, Financial Security, MBIA and Financial Guar-
anty should be evaluated independently of Moody's ratings. Any further explana-
tion as to the significance of the ratings may be obtained only from the appli-
cable rating agency.
 
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 or S&P, (2) unrated Municipal Obligations of invest-
ment grade quality in the opinion of Nuveen Advisory, with no fixed percentage
limitations on these unrated Municipal Obligations, and (3) temporary invest-
ments as described below, the income from which may be subject to state income
tax or to both federal and state income taxes.
 
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 non-appropriation lease obligations
are secured by the leased property, disposition of the property in the event of
foreclosure might prove difficult. Each Fund will seek to minimize the special
risks associated with such securities by not investing more than 10% of its as-
sets in lease obligations that contain non-appropriation clauses, and by only
investing in those nonappropriation leases where (1) the nature of the leased
equipment or property is such that its ownership or use is essential to a gov-
ernmental function of the municipality, (2) the lease payments will commence
amortization of principal at an early date resulting in an average life of
seven years or less for the lease obligation, (3) appropriate covenants will be
obtained from the municipal obligor prohibiting the substitution or purchase of
similar equipment if lease payments are not appropriated, (4) the lease obligor
has maintained good market acceptability in the past, (5) the investment is of
a size that will be attractive to institutional investors, and (6) the under-
 
14
<PAGE>
 
lying leased equipment has elements of portability and/or use that enhance its
marketability in the event foreclosure on the underlying equipment were ever
required. Lease obligations 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, such as the Federal Bankruptcy Reform Act of 1978. In addition, the
obligations of such issuers may become subject to the laws enacted in the fu-
ture by Congress, state legislatures or referenda extending the time for pay-
ment of principal and/or interest, or imposing other constraints upon enforce-
ment of such obligations or upon municipalities to levy taxes. There is also
the possibility that, as a result of legislation or other conditions, the power
or ability of any issuer to pay, when due, the principal of and interest on its
Municipal Obligations may be materially affected.
 
PORTFOLIO TRADING AND TURNOVER
   
Each Fund will make changes in its investment portfolio from time to time in
order to take advantage of opportunities in the municipal market and to limit
exposure to market risk. A Fund may also engage to a limited extent in short-
term trading consistent with its investment objective, but a Fund will not
trade securities solely to realize a profit. Securities may be sold in antici-
pation of market decline or purchased in anticipation of market rise and later
sold, but a Fund will not engage in trading solely to recognize a gain. In ad-
dition, a security may be sold and another of comparable quality purchased at
approximately the same time to take advantage of what Nuveen Advisory believes
to be a temporary disparity in the normal yield relationship between the two
securities. A Fund may make changes in its investment portfolio in order to
limit its exposure to changing market conditions. Changes in a Fund's invest-
ments are known as "portfolio turnover." While it is impossible to predict fu-
ture portfolio turnover rates, each Fund's annual portfolio turnover rate is
generally not expected to exceed 50%. 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 50% in particular
years depending upon market conditions. The portfolio turnover rates for the
National, Massachusetts and New York Funds for the fiscal year ended February
29, 1996 were 27%, 1% and 17%, respectively, and for the fiscal year ended Feb-
ruary 28, 1995, were 25%, 10% and 11%, respectively.     
 
WHEN-ISSUED SECURITIES
As described in the Prospectus, each Fund may purchase and sell Municipal Obli-
gations on a when-issued or delayed delivery basis. When-issued and delayed de-
livery transactions arise when securities are purchased or sold with payment
and delivery beyond the regular settlement date. (When-issued transactions nor-
mally 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 commit-
ment. The commitment to purchase securities on a when-issued or delayed deliv-
ery 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
 
                                                                              15
<PAGE>
 
makes the commitment to purchase a Municipal Bond 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 com-
mitment 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 de-
livery securities, such assets to be segregated by the Custodian specifically
for the settlement of such commitments. A Fund 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 each Fund reserves the
right to sell these securities before the settlement date if it is deemed ad-
visable. If a when-issued security is sold before delivery any gain or loss
would not be tax-exempt. A Fund commonly engages in when-issued transactions in
order to purchase or sell newly-issued Municipal Obligations, and may engage in
delayed delivery transactions in order to manage its operations more effective-
ly.
 
SPECIAL CONSIDERATIONS RELATING TO MUNICIPAL OBLIGATIONS OF DESIGNATED STATES
As described in the Prospectus, except for investments in temporary invest-
ments, the Massachusetts and New York Funds will, at all times, invest all of
their net assets in their respective state's Municipal Obligations. These Funds
are therefore more susceptible to political, economic or regulatory factors ad-
versely affecting issuers of Municipal Obligations in their states. Brief sum-
maries of these factors are contained in the Prospectus. Set forth below is ad-
ditional information that bears upon the risk of investing in Municipal Obliga-
tions issued by public authorities in these states. This information was ob-
tained 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.
 
FACTORS PERTAINING TO MASSACHUSETTS
As described above, except to the extent the Massachusetts Fund invests in tem-
porary investments, the Massachusetts Fund will invest substantially all of its
net assets in Massachusetts Municipal Obligations. The Massachusetts Fund is
therefore susceptible to political, economic or regulatory factors affecting
issuers of Massachusetts Municipal Obligations. Without intending to be com-
plete, the following briefly summarizes the current financial situation, as
well as some of the complex factors affecting the financial situation, in the
Commonwealth of Massachusetts (the "Commonwealth"). It is derived from sources
that are generally available to investors and is based in part on information
obtained from various agencies in Massachusetts. No independent verification
has been made of the accuracy or completeness of the following information.
 
 
There can be no assurance that current or future statewide or regional economic
difficulties, and the resulting impact on Commonwealth or local governmental
finances generally, will not adversely affect the market value of Massachusetts
Obligations in the Fund or the ability of particular obligors to make timely
payments of debt service on (or relating to) those obligations.
 
 
16

Since 1988, there has been a significant slowdown in the Commonwealth's econo-
my, as indicated by a rise in unemployment, a slowing of its per capita income
growth and declining state revenues. Since fiscal 1991, the Commonwealth's
revenues for state government programs have exceeded expenditures however, no
assurance can be given that lower than expected tax revenues will not resume
and continue.     
   
1996 Fiscal Year Budget. On July 21, 1995, the Governor signed the Common-
wealth's budget for fiscal 1996. The fiscal 1996 budget is based on estimated
budgeted revenues and other sources of approximately $16.778 billion, which
includes fiscal 1996 tax revenues of $11.653 billion. Estimated fiscal 1996
tax revenues are approximately $490 million, or 4.3%, higher than estimated
fiscal 1995 tax revenues.     
   
Fiscal 1996 non-tax revenues are projected to total $5.58 billion, approxi-
mately $66 million, or 1.3%, less than fiscal 1995 non-tax revenues of approx-
imately $5.224 billion. Federal reimbursements are projected to decrease by
approximately $1 million from approximately $2.970 billion in fiscal 1995 to
approximately $2.969 billion in fiscal 1996, primarily as a result of in-
creased reimbursements for Medicare spending, offset by a reduction in reim-
bursements received in 1995 for one-time Medicare expenses incurred in fiscal
1994 and fiscal 1995. Fiscal 1996 departmental revenues are projected to de-
cline by approximately $94 million, or 7.4%, from approximately $1.273 billion
in fiscal 1995 to approximately $1.179 billion in fiscal 1996. Major changes
in projected non-tax received for fiscal 1996 include a decline in motor vehi-
cle license and registration fees, reduction of abandoned property revenues
and a decrease due to non-recurring revenues received in fiscal 1995 from hos-
pitals and nursing homes as part of Medicare fiscal rate settlements and other
reimbursements by municipal hospitals to the state.     
   
Fiscal 1996 appropriations in the Annual Appropriations Act total approxi-
mately $16.847 billion, including approximately $25 million in gubernatorial
vetoes overridden by the legislature. In the final supplemental budget for
fiscal 1995, approved on August 24, 1995, another $71.1 million of appropria-
tions were continued for use in for 1996.     
   
As of February 1, 1996, the Governor had signed into law fiscal 1996 supple-
mental appropriations totalling approximately $23.5 million, including approx-
imately $12.6 million to fund higher education collective bargaining contracts
and $5.6 million for the Department of Social Services. These appropriations
were offset by approximately $10.4 million in line item reductions, including
a reduction of $9.8 million for the state's debt service contract assistance
to the MBTA. Both the House and Senate have passed supplemental appropriation
bills totalling $64.8 million primarily relating to snow and ice removal costs
incurred by both the Commonwealth and cities and towns. The bills are cur-
rently awaiting resolution by a conference committee of the House and Senate.
On January 26, 1996 and February 9, 1996, the Governor filed additional sup-
plemental appropriation bills totalling approximately $7.3 million for costs
relating to prison overcrowding relief as well as reimbursement costs associ-
ated with a court settlement. No action has been taken on these bills by ei-
ther branch of the Legislature.     
   
As of May 28, 1996, fiscal 1996 projected spending is approximately $16.963
billion, including approximately $153.2 million reserved for contingencies.
Projected revenues are approximately $16.851 billion.     
 
                                                                             17

The fiscal 1996 tax revenue projection is $11.684 billion, which represents an
increase of approximately $80 million from the earlier estimate, based upon tax
revenue collections through April 1996.     
   
The fiscal 1996 budget is based on numerous spending and revenue estimates the
achievement of which cannot be assured.     
   
1995 Fiscal Year. Budgeted revenues and other sources, including non-tax reve-
nues, collected in fiscal 1995 were approximately $16.387 billion, approxi-
mately $837 million, or 5.4%, above fiscal 1994 revenues of $15.550 billion.
Fiscal 1995 tax revenues collections were approximately $11.163 billion, ap-
proximately $12 million above the Department of Revenue's revised fiscal year
1995 tax revenue estimate of $10.151 billion and $556 million, or 5.2%, above
fiscal year tax revenues of $10.607 billion.     
   
Budgeted expenditures and other uses of funds in fiscal 1995 were approximately
$16.251 billion, approximately $728 million, or 4.7%, above fiscal 1994 bud-
geted expenditures and uses of $15.523 billion. The Commonwealth ended fiscal
1995 with an operating gain of $137 million and an ending fund balance of $726
million.     
       
On February 10, 1995, the Governor signed into law certain reforms to the Com-
monwealth's program for Aid to Families with Dependent Children ("AFDC") which
take effect on July 1, 1995, subject to federal approval of certain waivers.
The revised program reduces AFDC benefits to able bodied recipients by 2.75%,
while allowing them to keep a larger portion of their earned wages, requires
approximately 22,000 able-bodied parents of school-aged children to work or
perform community service for 20 hours per week and requires approximately
16,000 recipients who have children between the ages of two and six to partici-
pate in an education or training program or perform community service. The plan
also establishes a pilot program for up to 2,000 participants that offers tax
credits and wage subsidies to employers who hire welfare recipients. Parents
who find employment will be provided with extended medical benefits and day
care benefits for up to one year. The plan mandates paternal identification,
expands funding for anti-fraud initiatives, and requires parents on AFDC to im-
munize their children. Parents who are disabled, caring for a disabled child,
have a child under the age of two, or are teen-agers living at home and attend-
ing high school, will continue to receive cash assistance. Since most provi-
sions of the new law do not take effect until July 1, 1995, the Executive Of-
fice for Administration projects that the reforms will not materially affect
fiscal 1995 public assistance spending. The fiscal 1995 expenditure estimate of
$16.449 billion includes $247.8 million appropriated to fund the Commonwealth's
public assistance programs for the last four months of fiscal 1995. The Common-
wealth is currently evaluating the new law's impact on fiscal 1996 projected
spending for public assistance programs.
       
On November 8, 1994, the voters in the statewide general election approved an
initiative petition that would slightly increase the portion of the gasoline
tax revenue credited to the Highway Fund, one of the Commonwealth's three major
budgetary funds, prohibit the transfer of money from the Highway Fund to other
funds for non-highway purposes and not permit including the Highway Fund bal-
ance in the computation "consolidated net surplus" for purposes of state fi-
nance laws. The initiative petition also provides that no more than 15% of gas-
oline tax revenues may be used for mass transportation purposes, such as expen-
ditures related to the Massachusetts Bay Transit Authority. The Executive Of-
fice of Admin-
 
18

istration and Finance is analyzing the effect, if any, this initiative peti-
tion, which became law on December 8, 1994, may have on the fiscal 1995 budget
and it currently does not expect it to have any materially adverse impact. This
is not a constitutional amendment and is subject to amendment or repeal by the
Legislature, which may also, notwithstanding the terms of the petition, appro-
priate moneys from the Highway Fund in such amounts and for such purposes as it
determines, subject only to a constitutional restriction that such moneys be
used for highways or mass transit purposes.
 
1994 Fiscal Year. Fiscal 1994 tax revenue collections were approximately
$10.607 billion, $87 million below the Department of Revenue's fiscal year 1994
tax revenue estimate of $10.694 billion and $677 million above fiscal 1993 tax
revenues of $9.930 billion. Budgeted revenues and other sources, including non-
tax revenues, collected in fiscal 1994 were approximately $15.550 billion. To-
tal revenues and other sources increased by approximately 5.7% from fiscal 1993
to fiscal 1994 while tax revenues increased by 6.8% for the same period. Bud-
geted expenditures and other uses of funds in fiscal 1994 were approximately
$15.523 billion, which is $826.5 million or approximately 5.6% higher than fis-
cal 1993 budgeted expenditures and other uses.
 
As of June 30, 1994, the Commonwealth showed a year-end cash position of ap-
proximately $757 million, as compared to a projected position of $599 million.
 
In June, 1993, the Legislature adopted and the Governor signed into law compre-
hensive education reform legislation. This legislation required an increase in
expenditures for education purposes above fiscal 1993 base spending of $1.288
billion of approximately $175 million in fiscal 1994. The Executive Office for
Administration and Finance expects the annual increases in expenditures above
the fiscal 1993 base spending of $1.288 billion to be approximately $396 mil-
lion in fiscal 1995, $625 million in fiscal 1996 and $868 million in fiscal
1997. Additional annual increases are also expected in later fiscal years. The
fiscal 1995 budget as signed by the Governor includes $896 million in appropri-
ations to satisfy this legislation.
 
1993 Fiscal Year. The Commonwealth's budgeted expenditures and other uses were
approximately $14.696 billion in fiscal 1993, which is approximately $1.280
billion or 9.6% higher than fiscal 1992 expenditures and other uses. Final fis-
cal 1993 budgeted expenditures were $23 million lower than the initial July
1992 estimates of fiscal 1993 budgeted expenditures. Budgeted revenues and
other sources for fiscal 1993 totalled approximately $14.710 billion, including
tax revenues of $9.930 billion. Total revenues and other sources increased by
approximately 6.9% from fiscal 1992 to fiscal 1993, while tax revenues in-
creased by 4.7% for the same period. Overall, fiscal 1993 ended with a surplus
of revenues and other sources over expenditures and other uses of $13.1 million
and aggregate ending fund balances in the budgeted operating funds of the Com-
monwealth of approximately $562.5 million. After payment in full of the distri-
bution of local aid to the Commonwealth's cities and towns ("Local Aid") and
the retirement of short term debt, the Commonwealth showed a year end cash po-
sition of approximately $622.2 million, as compared to a projected position of
$485.1 million.
 
1992 Fiscal Year. The Commonwealth's budgeted expenditures and other uses were
approximately $13.4 billion in fiscal 1992, which is $238.7 million or 1.7%
lower than fiscal 1991 budgeted expenditures. Final fiscal 1992 budgeted expen-
ditures were $300 million more than the initial July 1991
 
                                                                              19

estimates of budgetary expenditures, due in part to increases in certain human
services programs, including an increase of $268.7 million for the Medicaid
program and $50.0 million for mental retardation consent decree requirements.
Budgeted revenues and other sources for fiscal 1992 totalled approximately
$13.7 billion (including tax revenues of approximately $9.5 billion), reflect-
ing an increase of approximately 0.7% from fiscal 1991 to 1992 and an increase
of 5.4% in tax revenues for the same period. Overall, fiscal 1992 is estimated
to have ended with an excess of revenues and other sources over expenditures
and other uses of $312.3 million. After payment in full of Local Aid in the
amount of $514.0 million due on June 30, 1992, retirement of the Common-
wealth's outstanding commercial paper (except for approximately $50 million of
bond anticipation notes) and certain other short term borrowings, as of June
30, 1992, the end of fiscal 1992, the Commonwealth showed a year-end cash po-
sition of approximately $731 million, as compared with the Commonwealth's cash
balance of $182.3 million at the end of fiscal 1991.
 
1991 Fiscal Year. Budgeted expenditures for fiscal 1991 were approximately
$13.659 billion, as against budgeted revenues and other sources of approxi-
mately $13.634 billion. The Commonwealth suffered an operating loss of approx-
imately $21.2 million. Application of the adjusted fiscal 1990 fund balances
of $258.3 million resulted in a fiscal 1991 budgetary surplus of $237.1 mil-
lion. State law requires that approximately $59.2 million of the fiscal year
ending balances of $237.1 million be placed in the Stabilization Fund, a re-
serve from which funds can be appropriated (i) to make up any difference be-
tween actual state revenues in any fiscal year in which actual revenues fall
below the allowable amount, (ii) to replace state and local losses by federal
funds or (iii) for any event, as determined by the legislature, which threat-
ens the health, safety or welfare of the people or the fiscal stability of the
Commonwealth or any of its political subdivisions.
 
Upon taking office in January 1991, the new Governor proposed a series of leg-
islative and administrative actions, including withholding of allotments under
Section 9C of Chapter 29 of the General Laws, intended to eliminate the pro-
jected deficits. The new Governor's review of the Commonwealth's budget indi-
cated projected spending of approximately $14.1 billion with an estimated $850
million in budget balancing measures that would be needed prior to the close
of fiscal 1991. At that time, estimated tax revenues were revised to approxi-
mately $8.8 billion, $903 million less than was estimated at the time the fis-
cal 1991 budget was adopted. The Legislature adopted a number of the Gover-
nor's recommendations and the Governor took certain administrative actions not
requiring legislative approval, including the adoption of a state employee
furlough program. It is estimated by the Commonwealth that spending reductions
achieved through savings initiatives and withholding of allotments total ap-
proximately $484.3 million in aggregate for fiscal 1991. However, these sav-
ings and reductions may be impacted negatively by litigation pursued by third
parties concerning the Governor's actions under Section 9C of Chapter 29 of
the General Laws and with regard to the state employee furlough program.
 
In addition, the new administration in May 1991 filed an amendment to its Med-
icaid state plan that enables it to claim 50% federal reimbursement on
uncompensated care payments for certain hospitals in the Commonwealth. As a
result, in fiscal 1991, the Commonwealth obtained additional non-tax revenues
in the form of federal reimbursements equal to approximately $513 million on
account of uncompensated care payments. This reimbursement claim was based
upon recent amendments of federal law contained in the Omnibus Budget Recon-
ciliation Act of 1990 and, consequently, on relatively
 
20
<PAGE>
 
undeveloped federal laws, regulations and guidelines. At the request of the
federal Health Care Financing Administration, the Office of Inspector General
of the United States Department of Health and Human Services has commenced an
audit of the reimbursement. The administration, which had reviewed the matter
with the Health Care Financing Administration prior to claiming the reimburse-
ment, believes that the Commonwealth will prevail in the audit. If the Common-
wealth does not prevail, the Commonwealth would have the right to contest an
appeal, but could be required to pay all or part of Medicaid reimbursements
with interest and to have such amount deducted from future reimbursement pay-
ments.
       
          
Employment. Reversing a trend of relatively low unemployment during the early
and mid 1980's, the Massachusetts unemployment rate beginning in 1990 increased
significantly to where the Commonwealth's unemployment rate exceeded the na-
tional unemployment rate. During 1990, the Massachusetts unemployment rate in-
creased from 4.5% in January to 6.1% in July to 6.7% in August. During 1991,
the Massachusetts unemployment rate averaged 9.0% while the average United
States unemployment rate was 6.7%. The Massachusetts unemployment rate during
1992 averaged 8.5% while the average United States unemployment rate was 7.4%.
Since 1993, the average monthly unemployment rate has declined steadily. The
Massachusetts unemployment rate in February 1996 was 5.0%, as compared with the
United States unemployment rate of 5.5% for the same period. Other factors
which may significantly and adversely affect the employment rate in the Common-
wealth include reductions in federal government spending on defense-related in-
dustries. Due to this and other considerations, there can be no assurance that
unemployment in the Commonwealth will not increase in the future.     
 
Debt Ratings. S&P currently rates the Commonwealth's uninsured general obliga-
tion bonds at A+. At the same time, S&P currently rates state and agency notes
at SP1. From 1989 through 1992, the Commonwealth had experienced a steady de-
cline in its S&P rating, with its decline beginning in May 1989, when S&P low-
ered its rating on the Commonwealth's general obligation bonds and other Com-
monwealth obligations from AA+ to AA and continuing a series of further reduc-
tions until March 1992, when the rating was affirmed at BBB.
 
Moody's currently rates the Commonwealth's uninsured general obligation bonds
at A1. From 1989 through 1992, the Commonwealth had experienced a steady de-
cline in its rating by Moody's since May 1989. In May 1989, Moody's lowered its
rating on the Commonwealth's notes from MIG-1 to MIG-2, and its rating on the
Commonwealth's commercial paper from P-1 to P-2. On June 21, 1989, Moody's re-
duced the Commonwealth's general obligation rating from Aa to A. On November
15, 1989, Moody's reduced the rating on the Commonwealth's general obligations
from A to Baa1, and on March 9, 1990, Moody's reduced the rating of the Common-
wealth's general obligation bonds from Baa1 to Baa.
 
There can be no assurance that these ratings will continue.
 
In recent years, the Commonwealth and certain of its public bodies and munici-
palities have faced serious financial difficulties which have affected the
credit standing and borrowing abilities of Massachusetts and its respective en-
tities and may have contributed to higher interest rates on debt obligations.
The continuation of, or an increase in, such financial difficulties could re-
sult in declines in the market values of, or default on, existing obligations
including Massachusetts Obligations in the Fund. Should there be
 
                                                                              21
<PAGE>
 
during the term of the Fund a financial crisis relating to Massachusetts, its
public bodies or municipalities, the market value and marketability of all
outstanding bonds issued by the Commonwealth and its public authorities or mu-
nicipalities including the Massachusetts Obligations in the Fund and interest
income to the Fund could be adversely affected.
   
Total Bond and Note Liabilities. The total general obligation bond indebted-
ness of the Commonwealth (including Dedicated Income Tax Debt and Special Ob-
ligation Debt) as of April 1, 1996 was approximately $10.093 billion. There
were also outstanding approximately $240 million in general obligation notes
and other short term general obligation debt. The total bond and note liabili-
ties of the Commonwealth as of April 1, 1996, including guaranteed bond and
contingent liabilities was approximately $13.818 billion.     
   
Debt Service. During the 1980s, capital expenditures were increased substan-
tially, which has had a short term impact on the cash needs of the Common-
wealth and also accounts for a significant rise in debt service during that
period. In November, 1988, the Executive Office for Administration and Finance
established an administrative limit on state-financed capital spending in the
Capital Projects Fund of $925 million per fiscal year. Capital expenditures
were $847.0 million, $694.1 million, $575.9 million, $760.6 million and $902.2
million in fiscal 1991, fiscal 1992, fiscal 1993, fiscal 1994 and fiscal 1995,
respectively. Commonwealth-financed capital expenditures are projected to be
approximately $898.0 million in fiscal 1996. Debt service expenditures for
fiscal 1991, fiscal 1992, fiscal 1993, fiscal 1994 and fiscal 1995 were $942.3
million, $898.3 million, $1.140 billion, $1.149 billion, and $1.231 billion,
respectively, and are projected to be approximately $1.199 billion for fiscal
1996. The amounts represented do not include debt service on notes issued to
finance certain Medicare-related liabilities, certain debt service contract
assistance payment to Massachusetts Bay Transportation Authority ($205.5 mil-
lion projected in fiscal 1996), the Massachusetts Convention Center ($24.6
million projected in fiscal 1996), the Massachusetts Government Land Bank ($6
million projected in fiscal 1996), the Massachusetts Water Pollution Abatement
Trust ($16.6 million projected in fiscal 1996) and grants to municipalities
under the school building assistance program to defray a portion of the debt
service costs on local school bonds ($174.5 million projected in fiscal 1996).
    
       
In January 1990, legislation was passed to impose a limit on debt service be-
ginning in fiscal 1991, providing that no more than 10% of the total appropri-
ations in any fiscal year may be expended for payment of interest and princi-
pal on general obligation debt (excluding the Fiscal Recovery Bonds). The per-
centage of total appropriations expended from the budgeted operating funds for
debt service (excluding debt service on Fiscal Recovery Bonds) for fiscal 1994
is 5.6% which is projected to increase to 5.9% in fiscal 1995.
 
Certain Liabilities. Among the material future liabilities of the Commonwealth
are significant unfunded general liabilities of its retirement systems and a
program to fund such liabilities; a program whereby, starting in 1978, the
Commonwealth began assuming full financial responsibility for all costs of the
administration of justice within the Commonwealth; continuing demands to raise
aggregate aid to cities, towns, schools and other districts and transit au-
thorities above current levels; and Medicaid expenditures which have increased
each year since the program was initiated. The Commonwealth has signed consent
decrees to continue improving mental health care and programs for the mentally
retarded in
 
22
<PAGE>
 
order to meet federal standards, including those governing receipt of federal
reimbursements under various programs, and the parties in those cases have
worked cooperatively to resolve the disputed issues.
   
As a result of comprehensive legislation approved in January, 1988, the Common-
wealth is required, beginning in fiscal 1989 to fund future pension liabilities
currently and to amortize the Commonwealth's unfunded liabilities over 40
years. The funding schedule must provide for annual payments in each of the ten
years ending fiscal 1998 which are at least equal to the total estimated pay-
as-you-go pension costs in each year. As a result of this requirement, the
funding requirements for fiscal 1996, 1997 and 1998 are estimates to be in-
creased to approximately $1.007 billion, $1.061 billion and $1.128 billion, re-
spectively.     
   
Litigation. The Commonwealth is engaged in various lawsuits involving environ-
mental and related laws, including an action brought on behalf of the U.S. En-
vironmental Protection Agency alleging violations of the Clean Water Act and
seeking to enforce the clean-up of Boston Harbor. The MWRA, successor in lia-
bility to the Metropolitan District Commission, has assumed primary responsi-
bility for developing and implementing a court-approved plan for the construc-
tion of the treatment facilities necessary to achieve compliance with federal
requirements. Under the Clean Water Act, the Commonwealth may be liable for
costs of compliance in these or any other Clean Water cases if the MWRA or a
municipality is prevented from raising revenues necessary to comply with a
judgment. The MWRA currently projects that the total cost of construction of
the treatment facilities required under the court's order is approximately
$3.557 billion in current dollars, with approximately $1.046 billion to be
spent on or after June 30, 1995. On October 18, 1995, the court entered an or-
der which reduced the MWRA's obligation to build certain additional secondary
treatment facilities, which is estimated by the MWRA will save ratepayers ap-
proximately $165 million.     
 
The Department of Public Welfare has been sued for the alleged unlawful denial
of personal care attendant services to certain disabled Medicaid recipients.
The Superior Court has denied the plaintiff's motion for preliminary injunction
and has also denied the plaintiff's motion for class certification. If the
plaintiffs were to prevail on their claims and the Commonwealth were required
to provide all of the services sought by the plaintiffs to all similarly situa-
tion persons, it would substantially increase the annual cost to the Common-
wealth. The Department of Public Welfare currently estimates this increase to
be as much as $200 million per year.
 
There are also actions pending in which recipients of human services benefits,
such as welfare recipients, the mentally retarded, the elderly, the handi-
capped, children, residents of state hospitals and inmates of corrections in-
stitutions, seek expanded levels of services and benefits and in which provid-
ers of services to such recipients challenge the rates at which they are reim-
bursed by the Commonwealth. To the extent that such actions result in judgments
requiring the Commonwealth to provide expanded services or benefits or pay in-
creased rates, additional operating and capital expenditures might be needed to
implement such judgments.
          
In 1995, the Spaulding Rehabilitation Hospital ("Spaulding") filed an action to
enforce an agreement to acquire its property by eminent domain in connection
with the Central Artery/Third Harbor Tunnel Project. If successful, Spaulding
could recover the fair market value of its property in addition to its     
 
                                                                              23

relocation costs with respect to its personal property. The Commonwealth esti-
mates its potential liability at approximately $50 million.     
   
The Commonwealth faces an additional potential liability of approximately $40
million in connection with a taking by the Massachusetts Highway Department re-
lated to the relocation of Northern Avenue in Boston.     
 
In addition there are several tax matters in litigation which could result in
significant refunds to taxpayers if decisions unfavorable to the Commonwealth
are rendered. In BayBank, et al. v. Commissioner
   
of Revenue, the banks challenge the inclusion of income from tax exempt obliga-
tions in the measure of the bank excise tax. The Appellate Tax Board issued
findings of fact and a report in favor of the Commissioner of Revenue on Sep-
tember 30, 1993. The case is pending before the Supreme Judicial Court. The po-
tential liability is approximately $55 million, including similarly situated
banks and tax years after 1990.     
   
In National Association of Government Employees v. Commonwealth, the Superior
Court declared that a line item in the Commonwealth's general appropriations
act for fiscal 1994 that increased the state employees' percentage share of
their group health insurance premiums from 10% to 15% violated the terms of
several collective bargaining agreements, and therefore was invalid under the
United States Constitution as regards employees covered by the agreements. On
February 9, 1995, the Supreme Judicial Court vacated the Superior Court's deci-
sion and declared that the fiscal 1994 line item did not violate the contracts
clause. In June, 1995, the United States Supreme Court denied the plaintiff's
writ of certiorari. Several other unions have filed a companion suit asserting
that the premium increase similarly violated other collective bargaining agree-
ments. The latter suit is in its initial stages. Prior to the Supreme Judicial
Court's decision, the Commonwealth's aggregate liability is estimated to be ap-
proximately $32 million.     
 
A variety of other civil suits pending against the Commonwealth may also affect
its future liabilities. There include challenges to the Commonwealth's alloca-
tion of school aid under Section 9C of Chapter 29 of the General Laws and to
adopt a state employee furlough program. No prediction is possible as to the
ultimate outcome of these proceedings.
   
On March 22, 1995, the Supreme Judicial Court held in Perini Corporation v.
Commission of Revenues that certain deductions from the net worth measure of
the Massachusetts corporate excise tax violate the Commerce Clause of the
United States Constitution. On October 2, 1995, the United States Supreme Court
denied the Commonwealth's petition for writ of certiorari. The Department of
Revenue estimates that tax revenues in the amount of $40 to $55 million may be
abated as a result of the Supreme Judicial Court's decision.     
 
Many factors, in addition to those cited above, do or may have a bearing upon
the financial condition of the Commonwealth, including social and economic con-
ditions, many of which are not within the control of the Commonwealth.

Expenditure and Tax Limitation Measures. Limits have been established on state
tax revenues by legislation approved by the Governor on October 25, 1986 and by
an initiative petition approved by the voters on November 4, 1986. The Execu-
tive Office for Administration and Finance currently estimates that state tax
revenues will not reach the limit imposed by either the initiative petition or
the legislative enactment in fiscal 1992.
 
Proposition 2 1/2, passed by the voters in 1980, led to large reductions in
property taxes, the major source of income for cities and towns and large in-
creases in state aid to offset such revenue losses. According to the Executive
Office for Administration and Finance, all of the 351 cities and towns have now
achieved a property tax level of no more than 2.5% of full property values. Un-
der the terms of Proposition 2 1/2, the property tax levy can now be increased
annually for all cities and towns, almost all by 2.5% of the prior fiscal
year's tax levy plus 2.5% of the value of new properties and of significant im-
provements to property. Legislation has also been enacted providing for certain
local option taxes. A voter initiative petition approved at the statewide gen-
eral election in November, 1990 further regulates the distribution of Local Aid
of no less than 40% of collections from individual income taxes, sales and use
taxes, corporate excise taxes, and the balance of the state lottery fund. If
implemented in accordance with its terms (including appropriation of the neces-
sary funds), the petition as approved would shift several hundred million dol-
lars to direct Local Aid.
 
Other Tax Measures. To provide revenue to pay debt service on both the deficit
and Medicaid-related borrowings and to fund certain direct Medicaid expendi-
tures, legislation was enacted imposing an additional tax on certain types of
personal income for 1989 and 1990 taxable years at rates of 0.375% and 0.75%,
respectively, effectively raising the tax rate of 1989 from 5% to 5.375% and
for 1990 to 5.75%. Recent legislation has effectively further increased tax
rates to 5.95% for tax year 1990 to 6.25% for tax year 1991 and returning to
5.95% for tax year 1992 and subsequent tax years. The tax is applicable to all
personal income except income derived from dividends, capital gains, unemploy-
ment compensation, alimony, rent, interest, pensions, annuities and IRA/Keogh
distributions. The income tax rate on other interest (excluding interest on ob-
ligations of the United States and of the Commonwealth and its subdivisions),
dividends and net capital gains (after a 50% reduction) was increased from 10%
to 12% for tax year 1990 and subsequent years, by recently enacted legislation.
 
Estate Tax Revisions. The fiscal 1993 budget included legislation which gradu-
ally phases out the current Massachusetts estate tax and replaces it with a
"sponge tax" in 1997. The "sponge tax" is based on the maximum amount of the
credit for state taxes allowed for federal estate tax purposes. The estate tax
is phased out by means of annual increases in the basic exemption from the cur-
rent $200,000 level. The exemption is increased to $300,000 for 1993, $400,000
for 1994, $500,000 for 1995 and $600,000 for 1996. In addition, the legislation
includes a full marital deduction starting July 1, 1994. Currently the marital
deduction is limited to 50% of the Massachusetts adjusted gross estate. The
static fiscal impact of the phase out of the estate tax was estimated to be ap-
proximately $24.8 million in fiscal 1994 and is estimated to be approximately
$72.5 million in fiscal 1995.
 
Other Issuers of Massachusetts Obligations. There are a number of state agen-
cies, instrumentalities and political subdivisions of the Commonwealth that is-
sue Municipal Obligations, some of which may be conduit revenue obligations
payable from payments from private borrowers. These entities are subject to
 
                                                                              25

various economic risks and uncertainties, and the credit quality of the securi-
ties issued by them may vary considerably from the credit quality of obliga-
tions backed by the full faith and credit of the Commonwealth. The brief sum-
mary above does not address, nor does it attempt to address, any difficulties
and the financial situations of those other issuers of Massachusetts Obliga-
tions.
 
FACTORS PERTAINING TO NEW YORK
As described above, except to the extent the New York Fund invests in temporary
investments, the New York Fund will invest substantially all of its assets in
New York Municipal Obligations. The New York Fund is therefore susceptible to
political, economic or regulatory factors affecting New York State and govern-
mental bodies within New York State. Some of the more significant events and
conditions relating to the financial situation in New York are summarized be-
low. The following information provides only a brief summary of the complex
factors affecting the financial situation in New York, is derived from sources
that are generally available to investors and is believed to be accurate. It is
based
on information drawn from official statements and prospectuses issued by, and
other information reported by, the State of New York (the "State"), by its var-
ious public bodies (the "Agencies"), and by other entities located within the
State, including the City of New York (the "City"), in connection with the is-
suance of their respective securities.
 
There can be no assurance that current or future statewide or regional economic
difficulties, and the resulting impact on State or local government finances
generally, will not adversely affect the market value of New York Municipal Ob-
ligations held in the portfolio of the New York Fund or the ability of particu-
lar obligors to make timely payments of debt service on (or relating to) those
obligations.
 
(1) The State: The State has historically been one of the wealthiest states in
the nation. For decades, however, the State economy has grown more slowly than
that of the nation as a whole, gradually eroding the State's relative economic
affluence. Statewide, urban centers have experienced significant changes in-
volving migration of the more affluent to the suburbs and an influx of gener-
ally less affluent residents. Regionally, the older Northeast cities have suf-
fered because of the relative success that the South and the West have had in
attracting people and business. The City has also had to face greater competi-
tion as other major cities have developed financial and business capabilities
which make them less dependent on the specialized services traditionally avail-
able almost exclusively in the City. The State has for many years had a very
high state and local tax burden relative to other states. The burden of State
and local taxation, in combination with the many other causes of regional eco-
nomic dislocation, has contributed to the decisions of some businesses and in-
dividuals to relocate outside, or not locate within, the State.
   
Slowdown of Regional Economy. A national recession commenced in mid-1990. The
downturn continued throughout the State's 1990-91 fiscal year and was followed
by a period of weak economic growth during the 1991 and 1992 calendar years.
For calendar year 1993, the economy grew faster than in 1992, but still at a
very moderate rate as compared to other recoveries. Moderate economic growth
continued in calendar year 1994. Economic growth slowed within New York during
1995 as the expansion of the national economy moderated. The State has fore-
casted a slowdown in the expansion of the State's economy in 1996. The State's
economic growth continues to lag behind the nation's due in part to a signifi-
cant retrenchment in the banking and financial services industries, downsizing
by major

corporations, cutbacks in defense spending, and an oversupply of office build-
ings. Many uncertainties exist in forecasts of both the national and State
economies and there can be no assurance that the State's economy will perform
at a level sufficient to meet the State's projections of receipts and disburse-
ments.
   
1996-97 Fiscal Year. The Governor issued a proposed Executive Budget for the
1996-97 fiscal year (the "Proposed Budget") on December 15, 1995, which pro-
jected a balanced general fund and receipts and disbursements of $31.3 billion
and $31.2 billion, respectively. As of June 10, 1996, the State legislature had
not yet enacted, nor had the Governor and the legislature reached an agreement
on, the budget for the 1996-97 fiscal year which commenced on April 1, 1996.
The Governor and the State's legislature have agreed on or proposed a series of
short-term stopgap spending measures to fund state payrolls and advances to
certain municipalities and certain state programs. The delay in the enactment
of the budget may negatively affect certain proposed actions and reduce pro-
jected savings.     
   
The Proposed Budget and the 1996-97 Financial Plan provide for the closing of a
projected $3.9 billion budget gap in the 1996-97 fiscal year by cost-contain-
ment savings in social welfare programs, savings from State agency
restructurings, decreasing the level of some categories of local aid, new reve-
nue measures and a reduction in the number of state employees. Up to $1.3 bil-
lion of gap closing measures by the State are dependent upon federal actions
with respect to the Medicaid program that have not been enacted due to the fed-
eral budget impact. The Governor has proposed that, depending upon the ultimate
form of Medicaid relief provided to the states, any resulting gap would be
filled through a combination of increased revenues, additional cuts in spending
for social services, and so-called "one shot" sources of revenue or cost sav-
ings.     
   
The Proposed Budget and the 1996-97 Financial Plan may be impacted negatively
by uncertainties relating to the economy and tax collections. In particular,
should the national economy grow more slowly than forecasted by the State, rev-
enues received by the State would be adversely affected. In addition, proposed
retroactive changes to the federal tax treatment of capital gains would flow
through to the State and could significantly reduce tax receipts.     
   
1995-96 Fiscal Year. The Governor announced on April 3, 1996 that the State
ended its 1994-95 fiscal year with an operating surplus of approximately $445
million. The State Legislature enacted the State's 1995-96 fiscal year budget
on June 7, 1995, more than two months after the start of that fiscal year. As
of January 19, 1996, the updated 1995-96 State Financial Plan (the "Plan") pro-
jected total general fund receipts and disbursements each of $32.7 billion,
representing reductions in receipts and disbursements of $144 million and $103
million, respectively, from the amount set forth in the 1995-96 budget. The
Plan projected for a General Fund balance of approximately $172 million at the
close of the 1995-96 fiscal year.     
   
1994-95 Fiscal Year. The State ended the 1994-95 fiscal year with a General
Fund balance of approximately $158 million.      
 
Future Fiscal Years. There can be no assurance that the State will not face
substantial potential budget gaps in the future resulting from a significant
disparity between tax revenues projected from a lower recurring receipts base
and the spending required to maintain State programs at current levels. To
 
                                                                              27
<PAGE>
 
   
address any potential budgetary imbalance, the State may need to take signifi-
cant actions to align recurring receipts and disbursements. The Governor's bud-
get for fiscal year 1996-97 projects that budget gaps of $1.4 billion and $2.5
billion may need to be closed for fiscal years 1997-98 and 1998-99, respective-
ly.     
   
Indebtedness. As of March 31, 1995, the total amount of long-term State general
obligation debt authorized but unissued stood at $1.8 billion. As of the same
date, the State had approximately $5.2 billion in general obligation bonds, in-
cluding $149 million in bond anticipation notes outstanding.     
   
The State originally projected that its borrowings for capital purposes during
the State's 1995-96 fiscal year would consist of $248 million in general obli-
gation bonds and bond anticipation notes and $186 million in general obligation
commercial paper. The Legislature authorized the issuance of up to $33 million
in certificates of participation in pools of leases for equipment and real
property to be utilized by State agencies in fiscal year 1995-96. The Gover-
nor's budget for fiscal year 1996-97 projects approximately $400 million of
borrowings by the state for capital purposes. The projections of the State re-
garding its borrowings for any fiscal year are subject to change if actual re-
ceipts fall short of State projections or if other circumstances require.     
   
In June 1990, legislation was enacted creating the New York Local Government
Assistance Corporation ("LGAC"), a public benefit corporation empowered to is-
sue long-term obligations to fund certain payments to local governments tradi-
tionally funded through the State's annual seasonal borrowing. As of June 30,
1995, LGAC has issued its bonds to provide net proceeds of $4.7 billion com-
pleting the program.     
   
Financing of capital programs by other public authorities of the State is also
obtained from lease-purchase and contractual-obligation financing arrangements,
the debt service for which is paid from State appropriations. As of March 31,
1995, there were $18 billion of such other financing arrangements outstanding
and additional financings of this nature by public authorities. In addition,
certain agencies had issued and outstanding approximately $7.0 billion of
"moral obligation financings" as of March 31, 1995, which are to be repaid from
project revenues. While there has never been a default on moral obligation debt
of the State, the State would be required to make up any shortfall in debt
service.     
          
Ratings. Moody's rating of the State's general obligation bonds stood at A on
January 24, 1996, and S&P's rating stood at A- with a positive outlook, on Jan-
uary 24, 1996, an improvement from S&P's stable outlook from February 1994
through April 1993 and negative outlook prior to April 1993.     
 
Previously, Moody's lowered its rating to A on June 6, 1990, its rating having
been A1 since May 27, 1986. S&P lowered its rating from A to A- on January 13,
1992. S&P's previous ratings were A from March 1990 to January 1992, AA- from
August 1987 to March 1990 and A+ from November 1982 to August 1987.
   
Moody's maintained its A rating and S&P continued its A- rating in connection
with the State's issuance of $116 million of general obligation bonds in Janu-
ary 1996.

(2) The City and the Municipal Assistance Corporation ("MAC"): The City ac-
counts for approximately 40% of the State's population and personal income, and
the City's financial health affects the State in numerous ways.
 
In response to the City's fiscal crisis in 1975, the State took a number of
steps to assist the City in returning to fiscal stability. Among other actions,
the State Legislature (i) created MAC to assist with long-term financing for
the City's short-term debt and other cash requirements and (ii) created the
State Financial Control Board (the "Control Board") to review and approve the
City's budgets and four-year financial plans (the financial plans also apply to
certain City-related public agencies).
 
In recent years, the rate of economic growth in the City slowed substantially
as the City's economy entered a recession. While by some measures the City's
economy may have begun to recover, a number of factors, including poor perfor-
mance by the City's financial services companies, may prevent a significant im-
provement in the City's economy and may in fact negatively impact upon the
City's finances by reducing tax receipts. The City Comptroller has issued re-
ports concluding that the recession of the
City's economy may be ending, but there is little prospect of any significant
improvement in the near term.
   
Fiscal Year 1997 and the 1996-1999 Financial Plan. On January 31, 1996, the
Mayor released his preliminary $31 billion budget for fiscal year 1997, which
included $2.0 billion of deficit reduction measures and relied upon a $750 mil-
lion reduction in mandated welfare and Medicaid expenditures from the State and
a $643 million reduction in expenditures by City agencies and the Board of Edu-
cation ("BOE") budget. The Mayor has also received from MAC for $125 million in
fiscal year 1996 in return for a commitment by the City to cut projected City
spending by $125 million in fiscal year 1997 and each of the next three fiscal
years. On May 9, 1996, the Mayor released a revised fiscal year 1997 budget of
$32.7 billion that would reduce overall spending from fiscal year 1996 and im-
pose $1.1 billion in budget cuts on City agencies. The revised budget reduces
reliance on savings in welfare and Medicaid expenditures by $250 million and
restores $300 million of proposed tax cuts, including a recommended four year
extension of the City surcharge on personal income taxes.     
   
The City Council has not yet approved the Mayor's revised fiscal year 1997 bud-
get, although a tentative agreement on the budget was announced on June 10,
1996.     
   
The 1996-1999 Financial Plan (the "Plan"), as revised in May 1996 by the Mayor,
projected budget gaps of $1.4 and $2.3 billion for fiscal years 1998 and 1999,
respectively. The forecasted budget shortfall in fiscal year 2000 could be as
much as $2.9 million. The City Comptroller and State Comptroller have each
warned that the fiscal year 1997 budget includes significant revenue risks. The
State Comptroller has expressed concern that projected budget gaps for fiscal
years 1999 and 2000 are each in excess of $2 billion despite the City's signif-
icant cost-cutting efforts.     
   
The amount of gap closing measures requiring State action set forth in the Plan
is well in excess of proposed assistance to the City outlined in the Governor's
Proposed Budget. Due to the continuing federal budget impasse, the City cannot
be assured that its assumptions regarding the amount of federal aid or the im-
pact of changes in federal law upon its operations or tax receipts. An extended
delay by the     
 
                                                                              29
<PAGE>
 
   
State in adopting its 1996-97 fiscal year budget or in the adoption of the fed-
eral budget would negatively impact upon the City's financial condition and
ability to close budget gaps for fiscal years 1997 and thereafter.     
   
The Mayor was required to submit an executive budget for fiscal year 1997 to
the City Council in late April 1996. Due to continuing uncertainties related to
the amount of State and federal aid, the City Council extended the date by
which the Mayor was to submit such executive budget.     
   
Given the foregoing, there can be no assurance that the City will continue to
maintain a balanced budget during fiscal year 1997 or thereafter, or that it
can maintain a balanced budget without additional tax or other revenue in-
creases or reductions in City services, which could adversely affect the City's
economic base.     
 
Pursuant to State law, the City prepares a four-year annual financial plan,
which is reviewed and revised on a quarterly basis and which includes the
City's capital, revenue and expense projections. The City is required to submit
its financial plans to review bodies, including the Control Board. If the City
were to experience certain adverse financial circumstances, including the oc-
currence or the substantial likelihood and the imminence of the occurrence of
an annual operating deficit of more than $100 million or the loss of access to
the public credit markets to satisfy the City's capital and seasonal financial
requirements, the Control Board would be required by State law to exercise cer-
tain powers, including prior approval of City financial plans, proposed
borrowings and certain contracts.
   
The City depends on the State for State aid both to enable the City to balance
its budget and to meet its cash requirements. If the State experiences revenue
shortfalls or spending increases beyond its projections during its 1996-97 fis-
cal year or subsequent years, such developments could result in reductions in
projected State aid to the City. In addition, there can be no assurance that
State budgets for the 1997-98 or future fiscal years will be adopted by the
April 1 statutory deadline and that there will not be adverse effects on the
City's cashflow and additional City expenditures as a result of such delays.
       
The City projections set forth in the Plan are based on various assumptions and
contingencies which are uncertain and which may not materialize. Changes in ma-
jor assumptions could significantly affect the City's ability to balance its
budget as required by State law and to meet its annual cash flow and financing
requirements. Such assumptions and contingencies include the timing of any re-
gional and local economic recovery, the absence of wage increases in excess of
the increases assumed in its financial plan, employment growth, provision of
State and Federal aid and mandate relief, State legislative approval of future
State budgets, levels of education expenditures as may be required by State
law, adoption of future City budgets by the New York City Council, approval by
the Governor or the State Legislature and the cooperation of MAC with respect
to various other actions proposed in the Plan and changes in federal tax law.
       
The City's ability to maintain a balanced operating budget is dependent on
whether it can implement necessary service and personnel reduction programs
successfully. As discussed above, the City must identify additional expenditure
reductions and revenue sources to achieve balanced operating budgets for fiscal
year 1997 and thereafter. Any such proposed expenditure reductions will be dif-
ficult to implement     
 
30
<PAGE>
 
because of their size and the substantial expenditure reductions already im-
posed on City operations in recent years.
   
Attaining a balanced budget is also dependent upon the City's ability to mar-
ket its securities successfully in the public credit markets. On May 3, 1996,
the Mayor announced a $1 billion reduction in City capital spending over a
five year period through fiscal year 2000. The City's financing program for
fiscal years 1996 through 2000 contemplates capital spending of $14 billion,
which will be financed through issuance of general obligation bonds, Water Au-
thority Revenue Bonds and Covered Organization obligations, and will be used
primarily to reconstruct and rehabilitate the City's infrastructure and physi-
cal assets and to make capital investments. The City's financing program as-
sumes the receipt of approximately $1 billion from the sale of City's sewer
and water systems. However, the City Comptroller has obtained a court order
blocking such sale, which the City is appealing. In the event such appeal is
unsuccessful the City would be required to reduce capital spending during the
next four years or find additional sources of funds in such amount. A signifi-
cant portion of such bond financing is used to reimburse the City's general
fund for capital expenditures already incurred. In addition, the City issues
revenue and tax anticipation notes to finance its seasonal working capital re-
quirements. The terms and success of projected public sales of City general
obligation bonds and notes will be subject to prevailing market conditions at
the time of the sale, and no assurance can be given that the credit markets
will absorb the projected amounts of public bond and note sales. In addition,
future developments concerning the City and public discussion of such develop-
ments, the City's future financial needs and other issues may affect the mar-
ket for outstanding City general obligation bonds and notes. If the City were
unable to sell its general obligation bonds and notes, it would be prevented
from meeting its planned operating and capital expenditures.     
   
Absent appropriate legislative relief, the City may also face limitations on
its borrowing capacity after 1998 under the State's Constitution that will
prevent it from borrowing additional funds, as a result of the decrease in
real estate values within the City. The inability to finance capital improve-
ments would increase the City's budget gaps in later years or require it to
significantly curtail capital spending which would lead to a deterioration in
the City's infrastructure and ability to deliver services.     
   
The City is a defendant in a significant number of lawsuits and is subject to
numerous claims and investigations, including, but not limited to, actions
commenced and claims asserted against the City arising out of alleged consti-
tutional violations, torts, breaches of contracts, and other violations of law
and condemnation proceedings. While the ultimate outcome and fiscal impact, if
any, on the proceedings and claims are not currently predictable, adverse de-
terminations in certain of them might have a material adverse effect upon the
City's ability to carry out its financial plan. As of June 30, 1995, the City
estimated its potential future liability on outstanding claims to be $2.5
billion.     
 
On January 30, 1995, Robert L. Schulz and other defendants commenced a federal
district court action seeking among other matters to cancel the issuance on
January 31, 1995 of $659 million of City bonds. While the federal courts have
rejected requests for temporary restraining orders and expedited appeals, the
case is still pending. The City has indicated that it believes the action to
be without merit as it relates to the City, but there can be no assurance as
to the outcome of the litigation and an adverse ruling or the granting of a
permanent injunction would have a negative impact on the City's financial con-
dition and its ability to fund its operations.
 
                                                                             31

Fiscal Year 1996. New York City adopted its 1996 fiscal year budget in June
1995, and submitted its Financial Plan for the 1996 fiscal year to the Control
Board on July 11, 1995. The fiscal 1996 budget and Financial Plan originally
provided for spending of $31.4 billion and a closed budget gap of $3.1 billion.
However, in January 1996 additional unexpected budget gaps totaling approxi-
mately $760 million were identified in the fiscal 1996 budget. The widening of
the budget gap for fiscal year 1996 resulted from shortfalls in tax revenues
and State and federal aid and the failure to achieve Medicaid, welfare and
other savings at the levels projected. The City has undertaken a number of ac-
tions to close the recently discovered gap, including additional agency cuts,
refinancing of MAC debt, the proposed sale of the City's parking meters and the
proposed sale of approximately $250 million of uncollected tax liens. The City
Comptroller has questioned whether the City will be able to close the remaining
budget gap for fiscal year 1996 prior to fiscal year-end on June 30, 1996 and
has criticized certain gap-closing measures as being at the expense of future
revenues.     
          
Fiscal Years 1991 through 1995. The City achieved balanced operating results in
accordance with generally accepted accounting principles for fiscal years 1991
through 1995. The City was required to close substantial budget gaps in these
fiscal years in order to maintain balanced operating results.     
   
Ratings. As of the date of this prospectus, Moody's rating of the City's gen-
eral obligation bonds stood at Baa1 and S&P's rating stood at BBB+. On February
11, 1991, Moody's had lowered its rating from A.     
   
On March 1, 1996, Moody's confirmed its Baa1 rating in connection with a sched-
uled March 1996 sale of $1.3 billion of the City's general obligation bonds but
indicated that it would review such rating for a possible downgrade following
adoption of the City's 1997 fiscal year budget. S&P also confirmed its rating
of the City's general obligation bonds in connection with such general obliga-
tion bond issue in March 1996.     
   
In January 1995, in response to the City's plan to borrow $120 million to re-
fund debt due in February without imposing additional cuts in the fiscal 1995
budget, S&P placed the City on negative credit watch. In late May 1996, S&P
confirmed the City's rating citing improvements in the revised fiscal year 1997
budget. Any rating decrease would negatively affect the marketability of the
City's bonds and significantly increase the City's financing costs.     
 
On October 12, 1993, Moody's increased its rating of the City's issuance of
$650 million of Tax Anticipation Notes ("TANs") to MIG-1 from MIG-2. Prior to
that date, on May 9, 1990, Moody's revised downward its rating on outstanding
City revenue anticipation notes from MIG-1 to MIG-2
and rated the $900 million notes then being sold MIG-2. S&P's rating of the Oc-
tober 1993 TANs issue increased to SP-1 from SP-2. Prior to that date, on April
29, 1991, S&P revised downward its rating on City revenue anticipation notes
from SP-1 to SP-2.
   
As of December 31, 1995, the City and MAC had, respectively, $24.4 billion and
$4.0 billion of outstanding net long-term indebtedness.

(3) The State Agencies: Certain Agencies of the State have faced substantial
financial difficulties which could adversely affect the ability of such Agen-
cies to make payments of interest on, and principal amounts of, their respec-
tive bonds. The difficulties have in certain instances caused the State (under
so-called "moral obligation" provisions, which are non-binding statutory pro-
visions for State appropriations to maintain various debt service reserve
funds) to appropriate funds on behalf of the Agencies. Moreover, it is ex-
pected that the problems faced by these Agencies will continue and will re-
quire increasing amounts of State assistance in future years. Failure of the
State to appropriate necessary amounts or to take other action to permit those
Agencies having financial difficulties to meet their obligations could result
in a default by one or more of the Agencies. Such default, if it were to oc-
cur, would be likely to have a significant adverse affect on investor confi-
dence in, and therefore the market price of, obligations of the defaulting
Agencies. In addition, any default in payment on any general obligation of any
Agency whose bonds contain a moral obligation provision could constitute a
failure of certain conditions that must be satisfied in connection with Fed-
eral guarantees of City and MAC obligations and could thus jeopardize the
City's long-term financing plans.
   
As of September 30, 1994, the State reported that eighteen Agencies each had
outstanding debt of $100 million or more and an aggregate of $70.3 billion of
outstanding debt, some of which was state-supported, state-related debt.     
 
(4) State Litigation: The State is a defendant in numerous legal proceedings
pertaining to matters incidental to the performance of routine governmental
operations. Such litigation includes, but is not limited to, claims asserted
against the State arising from alleged torts, alleged breaches of contracts,
condemnation proceedings and other alleged violations of State and Federal
laws. Included in the State's outstanding litigation are a number of cases
challenging the constitutionality or the adequacy and effectiveness of a vari-
ety of significant social welfare programs primarily involving the State's
mental hygiene programs. Adverse judgments in these matters generally could
result in injunctive relief coupled with prospective changes in patient care
which could require substantial increased financing of the litigated programs
in the future.
 
The State is also engaged in a variety of claims wherein significant monetary
damages are sought. Actions commenced by several Indian nations claim that
significant amounts of land were unconstitutionally taken from the Indians in
violation of various treaties and agreements during the eighteenth and nine-
teenth centuries. The claimants seek recovery of approximately six million
acres of land, as well as compensatory and punitive damages.
       
(5) Other Municipalities: Certain localities in addition to New York City
could have financial problems leading to requests for additional State assis-
tance. The potential impact on the State of such actions by localities is not
included in projections of State receipts and expenditures in the State's
1994-95 fiscal year.
 
Fiscal difficulties experienced by the City of Yonkers ("Yonkers") resulted in
the creation of the Financial Control Board for the City of Yonkers (the "Yon-
kers Board") by the State in 1984. The Yonkers Board is charged with oversight
of the fiscal affairs of Yonkers. Future actions taken by the Governor or
 
                                                                             33
<PAGE>
 
the State Legislature to assist Yonkers could result in allocation of State re-
sources in amounts that cannot yet be determined.
   
Municipalities and school districts have engaged in substantial short-term and
long-term borrowings. In 1993, the total indebtedness of all localities in the
State (other than New York City) was approximately $17.7 billion. State law re-
quires the Comptroller to review and make recommendations concerning the bud-
gets of those local government units other than New York City authorized by
State law to issue debt to finance deficits during the period that such deficit
financing is outstanding. Fifteen localities had outstanding indebtedness for
State financing at the close of their fiscal year ending in 1993. In December
1995, in reaction to continuing financial problems, the Troy Municipal Assis-
tance Corp., which was created in 1995, imposed a 1996 budget plan upon Troy,
New York. Troy MAC had been expected to refinance $35 million of revenue bonds
issued by Troy, for which Troy lacks resources to fund debt service. Such reve-
nue bonds have not to date been refinanced. A similar municipal assistance cor-
poration has also been established for Newburgh. In addition, several other New
York cities, including Utica, Rome, Schenectady, Syracuse and Niagara Falls
have faced continuing budget deficits, as federal and state aid and local tax
revenues have declined while government expenses have increased. The financial
problems being experienced by the State's smaller urban centers place addi-
tional strains upon the State's financial condition at a time when the State is
struggling with its own budget gaps.     
   
Certain proposed Federal expenditure reductions could reduce, or in some cases
eliminate, Federal funding of some local programs and accordingly might impose
substantial increased expenditure requirements on affected localities to in-
crease local revenues to sustain those expenditures. In addition, proposed
changes in the treatment of capital gains for federal income tax purposes could
reduce the receipts of the State and City. If the State, New York City or any
of the Agencies were to suffer serious financial difficulties jeopardizing
their respective access to the public credit markets, the marketability of
notes and bonds issued by localities within the State, including notes or bonds
in the Fund, could be adversely affected. Localities also face anticipated and
potential problems resulting from certain pending litigation, judicial deci-
sions, and long-range economic trends. The longer-range potential problems of
declining urban population, increasing expenditures, and other economic trends
could adversely affect certain localities and require increasing State assis-
tance in the future.     
 
(6) Other Issuers of New York Municipal Obligations. There are a number of
other state agencies, instrumentalities and political subdivisions of the State
that issue Municipal Obligations, some of which may be conduit revenue obliga-
tions payable from payments from private borrowers. These entities are subject
to various economic risks and uncertainties, and the credit quality of the se-
curities issued by them may vary considerably from the credit quality of obli-
gations backed by the full faith and credit of the State.
 
CONSIDERATIONS RELATING TO FINANCIAL FUTURES AND OPTION CONTRACTS
As described in the Prospectus, each of the Funds may purchase and sell finan-
cial futures contracts, options on financial futures or related options for the
purpose of hedging its portfolio securities against declines in the value of
such securities, and to hedge against increases in the cost of securities the
Fund intends to purchase. To accomplish such hedging, a Fund may take an in-
vestment position in a futures
 
34
<PAGE>
 
contract or in an option which is expected to move in the opposite direction
from the position being hedged. Futures or options utilized for hedging pur-
poses would either be based on an index of long-term Municipal Obligations
(i.e., those with remaining maturities averaging 20-30 years) or relate to debt
securities whose prices are anticipated by Nuveen Advisory to correlate with
the prices of the Municipal Obligations owned by a Fund. The sale of financial
futures or the purchase of put options on financial futures or on debt securi-
ties or indexes is a means of hedging against the risk that the value of secu-
rities owned by a Fund may decline on account of an increase in interest rates,
and the purchase of financial futures or of call options on financial futures
or on debt securities or indexes is a means of hedging against increases in the
cost of the securities a Fund intends to purchase as a result of a decline in
interest rates. Writing a call option on a futures contract or on debt securi-
ties or indexes may serve as a hedge against a modest decline in prices of Mu-
nicipal Obligations held in a Fund's portfolio, and writing a put option on a
futures contract or on debt securities or indexes may serve as a partial hedge
against an increase in the value of Municipal Obligations a Fund intends to ac-
quire. The writing of such options provides a hedge to the extent of the pre-
mium received in the writing transaction. Regulations of the Commodity Futures
Trading Commission ("CFTC") applicable to the Funds require that transactions
in futures and options on futures be engaged in only for bona-fide hedging pur-
poses, and that no such transactions may be entered into by a Fund if the ag-
gregate initial margin deposits and premiums paid by that Fund exceeds 5% of
the market value of the Fund's assets. A Fund will not purchase futures unless
it has segregated cash, government securities or high grade liquid debt equal
to the contract price of the futures less any margin on deposit, or unless the
long futures position is covered by the sale of a put option. A Fund will not
sell futures unless the Fund owns the instruments underlying the futures or
owns options on such instruments or owns a portfolio whose market price may be
expected to move in tandem with the market price of the instruments or index
underlying the futures. In addition, each Fund is subject to the tax require-
ment that less than 30% of its gross income may be derived from the sale or
disposition of securities held for less than three months. With respect to its
engaging in transactions involving the purchase or writing of put and call op-
tions on debt securities or indexes, a Fund will not purchase such options if
more than 5% of its assets would be invested in the premiums for such options,
and it will only write "covered" or "secured" options, wherein the securities
or cash required to be delivered upon exercise are held by a Fund, with such
cash being maintained in a segregated account. These requirements and limita-
tions may limit a Fund's ability to engage in hedging transactions.
 
Description of Financial Futures and Options. A futures contract is a contract
between a seller and a buyer for the sale and purchase of specified property at
a specified future date for a specified price. An option is a contract that
gives the holder of the option the right, but not the obligation, to buy (in
the case of a call option) specified property from, or to sell (in the case of
a put option) specified property to, the writer of the option for a specified
price during a specified period prior to the option's expiration. Financial
futures contracts and options cover specified debt securities (such as U.S.
Treasury securities) or indexes designed to correlate with price movements in
certain categories of debt securities. At least one exchange trades futures
contracts on an index designed to correlate with the long-term municipal bond
market. Financial futures contracts and options on financial futures contracts
are traded on exchanges regulated by the CFTC. Options on certain financial in-
struments and financial indexes are traded in securities markets regulated by
the Securities and Exchange Commission. Although futures contracts and options
on specified financial instruments call for settlement by delivery of the fi-
nancial
 
                                                                              35
<PAGE>
 
instruments covered by the contracts, in most cases positions in these con-
tracts are closed out in cash by entering into offsetting, liquidating or clos-
ing transactions. Index futures and options are designed for cash settlement
only.
 
Risks of Futures and Options Transactions. There are risks associated with the
use of futures contracts and options for hedging purposes. Investment in
futures contracts and options involves the risk of imperfect correlation be-
tween movements in the price of the futures contract and options and the price
of the security being hedged. The hedge will not be fully effective where there
is imperfect correlation between the movements in the two financial instru-
ments. For example, if the price of the futures contract moves more than the
price of the hedged security, a Fund will experience either a loss or gain on
the future which is not completely offset by movements in the price of the
hedged securities. Further, even where perfect correlation between the price
movements does occur, a Fund will sustain a loss at least equal to the commis-
sions on the financial futures transaction. To compensate for imperfect correc-
tions, the Funds may purchase or sell futures contracts in a greater dollar
amount than the hedged securities if the volatility of the hedged securities is
historically greater than the volatility of the futures contracts. Conversely,
the Funds may purchase or sell fewer futures contracts if the volatility of the
price of the hedged securities is historically less than that of the futures
contracts.
 
Because of low initial margin deposits made upon the opening of a futures posi-
tion, futures transactions involve substantial leverage. As a result, rela-
tively small movements in the price of the futures contract can result in sub-
stantial unrealized gains or losses. Because the Funds will engage in the pur-
chase and sale of financial futures contracts solely for hedging purposes, how-
ever, any losses incurred in connection therewith should, if the hedging strat-
egy is successful, be offset in whole or in part by increases in the value of
securities held by the Funds or decreases in the price of securities the Funds
intend to acquire.
 
The Funds expect to liquidate a majority of the financial futures contracts
they enter into through offsetting transactions on the applicable contract mar-
ket. There can be no assurance, however, that a liquid secondary market will
exist for any particular futures contract at any specific time. Thus, it may
not be possible to close a futures position. In the event of adverse price
movements, the Funds would continue to be required to make daily cash payments
of variation margin. In such situations, if a Fund has sufficient cash, it may
be required to sell portfolio securities to meet daily variation margin re-
quirements at a time when it may be disadvantageous to do so. The inability to
close out futures positions also could have an adverse impact on a Fund's abil-
ity to hedge its portfolio effectively and may expose the Fund to risk of loss.
The Funds will enter into a futures position only if, in the judgment of Nuveen
Advisory, there appears to be an actively traded secondary market for such
futures contracts.
 
The liquidity of a secondary market in a futures contract may be adversely af-
fected by "daily price fluctuation limits" established by commodity exchanges
which limit the amount of fluctuation in a futures contract price during a sin-
gle trading day. Once the daily limit has been reached in the contract, no
trades may be entered into at a price beyond the limit, thus preventing the
liquidation of open futures positions. Prices have in the past moved the daily
limit on a number of consecutive trading days.
 
The successful use of transactions in futures also depends on the ability of
Nuveen Advisory to forecast the direction and extent of interest rate movements
within a given time frame. To the extent these
 
36
<PAGE>
 
prices remain stable during the period in which a futures contract is held by a
Fund or moves in a direction opposite to that anticipated, the Fund may realize
a loss on the hedging transaction which is not fully or partially offset by an
increase in the value of portfolio securities. As a result, the Fund's total
return for such period may be less than if it had not engaged in the hedging
transaction.
 
The ability of each of the Funds to engage in transactions in futures contracts
may be limited by the tax requirement that it have less than 30% of its gross
income derived from the sale or other disposition of stock or securities held
for less than three months. Gain from transactions in futures contracts will be
taxable to a Fund's shareholders partially as short-term and partially as long-
term capital gain.
 
TEMPORARY INVESTMENTS
The Prospectus discusses briefly the ability of each Fund to invest a portion
of its assets in federally tax-exempt or taxable "temporary investments." Tem-
porary investments will not exceed 20% of any Fund's assets except when made
for defensive purposes. The Funds will invest only in taxable temporary invest-
ments that are either U.S. Government securities or are rated within the high-
est grade by Moody's or S&P, and mature within one year from the date of pur-
chase or carry a variable or floating rate of interest.
 
The Funds may invest in the following federally tax-exempt temporary invest-
ments:
 
Bond Anticipation Notes (BANs) are usually general obligations of state and lo-
cal governmental issuers which are sold to obtain interim financing for pro-
jects that will eventually be funded through the sale of long-term debt obliga-
tions or bonds. The ability of an issuer to meet its obligations on its BANs is
primarily dependent on the issuer's access to the long-term municipal bond mar-
ket and the likelihood that the proceeds of such bond sales will be used to pay
the principal and interest on the BANs.
 
Tax Anticipation Notes (TANs) are issued by state and local governments to fi-
nance the current operations of such governments. Repayment is generally to be
derived from specific future tax revenues. Tax anticipation notes are usually
general obligations of the issuer. A weakness in an issuer's capacity to raise
taxes due to, among other things, a decline in its tax base or a rise in delin-
quencies, could adversely affect the issuer's ability to meet its obligations
on outstanding TANs.
 
Revenue Anticipation Notes (RANs) are issued by governments or governmental
bodies with the expectation that future revenues from a designated source will
be used to repay the notes. In general, they also constitute general obliga-
tions of the issuer. A decline in the receipt of projected revenues, such as
anticipated revenues from another level of government, could adversely affect
an issuer's ability to meet its obligations on outstanding RANs. In addition,
the possibility that the revenues would, when received, be used to meet other
obligations could affect the ability of the issuer to pay the principal and in-
terest on RANs.
 
Construction Loan Notes are issued to provide construction financing for spe-
cific projects. Frequently, these notes are redeemed with funds obtained from
the Federal Housing Administration.
 
                                                                              37
<PAGE>
 
Bank Notes are notes issued by local government bodies and agencies as those
described above to commercial banks as evidence of borrowings. The purposes for
which the notes are issued are varied but they are frequently issued to meet
short-term working capital or capital-project needs. These notes may have risks
similar to the risks associated with TANs and RANs.
 
Tax-Exempt Commercial Paper (Municipal Paper) represents very short-term
unsecured, negotiable promissory notes, issued by states, municipalities and
their agencies. Payment of principal and interest on issues of municipal paper
may be made from various sources, to the extent the funds are available there-
from. Maturities of municipal paper generally will be shorter than the maturi-
ties of TANs, BANs or RANs. There is a limited secondary market for issues of
municipal paper.
 
While these various types of notes as a group represent the major portion of
the tax-exempt note market, other types of notes are occasionally available in
the marketplace and each Fund may invest in such other types of notes to the
extent permitted under its investment objective, policies and limitations. Such
notes may be issued for different purposes and may be secured differently from
those mentioned above.
 
The Funds may also invest in the following taxable temporary investments:
 
U.S. Government Direct Obligations are issued by the United States Treasury and
include bills, notes and bonds.
 
- --Treasury bills are issued with maturities of up to one year. They are issued
 in bearer form, are sold on a discount basis and are payable at par value at
 maturity.
 
- --Treasury notes are longer-term interest bearing obligations with original ma-
 turities of one to seven years.
 
- --Treasury bonds are longer-term interest-bearing obligations with original ma-
 turities from five to thirty years.
 
U.S. Government Agencies Securities--Certain federal agencies have been estab-
lished as instrumentalities of the United States Government to supervise and
finance certain types of activities. These agencies include, but are not lim-
ited to, the Bank for Cooperatives, Federal Land Banks, Federal Intermediate
Credit Banks, Federal Home Loan Banks, Federal National Mortgage Association,
Government National Mortgage Association, Export-Import Bank of the United
States, and Tennessee Valley Authority. Issues of these agencies, while not di-
rect obligations of the United States Government, are either backed by the full
faith and credit of the United States or are guaranteed by the Treasury or sup-
ported by the issuing agencies' right to borrow from the Treasury. There can be
no assurance that the United States Government itself will pay interest and
principal on securities as to which it is not legally so obligated.
 
Certificates of Deposit (CDs)--A certificate of deposit is a negotiable inter-
est bearing instrument with a specific maturity. CDs are issued by banks in ex-
change for the deposit of funds and normally can be traded in the secondary
market, prior to maturity. The Funds will only invest in U.S. dollar denomi-
nated CDs issued by U.S. banks with assets of $1 billion or more.
 
38
<PAGE>
 
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 inter-
est.
 
Repurchase Agreements--A repurchase agreement is a contractual agreement
whereby the seller of securities (U.S. Government or Municipal Obligations)
agrees to repurchase the same security at a specified price on a future date
agreed upon by the parties. The agreed upon repurchase price determines the
yield during 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 opin-
ion 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 the Funds 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 addi-
tion, if bankruptcy proceedings are commenced with respect to the seller of the
security, realization upon the collateral by the Funds may be delayed or limit-
ed. Nuveen Advisory will monitor the value of collateral at the time the trans-
action is entered into and at all times subsequent during the term of the re-
purchase 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 de-
clined below the repurchase price, Nuveen Advisory will demand additional col-
lateral from the issuer to increase the value of the collateral to at least
that of the repurchase price. A Fund will not invest more than 10% of its as-
sets in repurchase agreements maturing in more than seven days.
 
RATINGS OF INVESTMENTS
   
The four highest ratings of Moody's for Municipal Obligations are Aaa, Aa, A
and Baa. Municipal Obligations rated Aaa are judged to be of the "best quali-
ty." The rating of Aa is assigned to Municipal Obligations which are of "high
quality by all standards," but as to which margins of protection or other ele-
ments make long-term risks appear somewhat larger than in Aaa rated Municipal
Obligations. The Aaa and Aa rated Municipal Obligations comprise what are gen-
erally known as "high grade bonds." Municipal Obligations that are rated A by
Moody's possess many favorable investment attributes and are considered upper
medium grade obligations. Factors giving security to principal and interest of
A rated Municipal Obligations are considered adequate, but elements may be
present which suggest a susceptibility to impairment sometime in the future.
Municipal Obligations rated Baa by Moody's are considered medium grade obliga-
tions (i.e., they are neither highly protected nor poorly secured). Such bonds
lack outstanding investment characteristics and in fact have speculative char-
acteristics as well. Moody's bond rating symbols may contain numerical modifi-
ers of a generic rating classification. The modifier 1 indicates that the bond
ranks at the high end of its category; the modifier 2 indicates a mid-range
ranking; and the modifier 3 indicates that the issue ranks in the lower end of
its general rating category.     
 
                                                                              39
<PAGE>
 
   
The four highest ratings of S&P for Municipal Obligations are AAA, AA, A and
BBB. Municipal Obligations rated AAA have an extremely strong capacity to pay
principal and interest. The rating of AA indicates that capacity to pay prin-
cipal 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 capac-
ity to pay principal and interest, although such bonds are somewhat more sus-
ceptible to the adverse effects of changes in circumstances and economic con-
ditions. The BBB rating is the lowest "investment grade" security rating by
S&P. Municipal Obligations rated BBB are regarded as having an adequate capac-
ity to pay principal and interest. Whereas such bonds normally exhibit ade-
quate 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 "Other Corporate Obligations" category of temporary investments are corpo-
rate (as opposed to municipal) debt obligations rated AAA by S&P or Aaa by
Moody's. Corporate debt obligations rated
AAA by S&P have an extremely strong capacity to pay principal and interest.
The Moody's corporate debt rating of Aaa is comparable to that set forth above
for Municipal Obligations.
 
Subsequent to its purchase by 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 the Fund's
portfolio, but Nuveen Advisory will consider such an event in its determina-
tion of whether the Fund should continue to hold such obligation.
 
                                  MANAGEMENT
   
The management of Nuveen Insured Tax-Free Bond Fund, Inc., including general
supervision of the duties performed for the Funds under the Investment Manage-
ment Agreement, is the responsibility of its Board of Directors. Nuveen In-
sured Tax-Free Bond Fund, Inc. currently has six directors, two of whom are
"interested persons" (as the term "interested persons" is defined in the In-
vestment Company Act of 1940) and four of whom are "disinterested persons."
The names and business addresses of the directors and officers of Nuveen In-
sured Tax-Free Bond Fund, Inc. and their principal occupations and other af-
filiations during the past five years are set forth below, with those direc-
tors who are "interested persons" indicated by an asterisk.

             INVESTMENT ADVISER AND INVESTMENT MANAGEMENT AGREEMENT
 
Nuveen Advisory Corp. acts as investment adviser for and manages the investment
and reinvestment of the assets of each of the Funds. Nuveen Advisory also ad-
ministers Nuveen Insured Tax-Free Bond Fund's business affairs, provides office
facilities and equipment and certain clerical, bookkeeping and administrative
services, and permits any of its officers or employees to serve without compen-
sation as directors or officers of the Nuveen Insured Tax-Free Bond Fund, Inc.
if elected to such positions. See "Management of the Funds" in the Prospectus.
 
Pursuant to an investment management agreement between Nuveen Advisory and
Nuveen Insured Tax-Free Bond Fund, Inc., the Funds have agreed to pay annual

erage daily net asset value of any class of shares of each Fund for any fiscal
year, Nuveen Advisory has agreed to waive all or a portion of its management
fees or reimburse certain expenses of each Fund. Nuveen Advisory may also vol-
untarily agree to reimburse additional expenses from time to time, which volun-
tary reimbursements may be terminated at any time in its discretion. For the
last three fiscal years, the Funds paid net management fees to Nuveen Advisory

As discussed in the Prospectus, in addition to the management fees of Nuveen
Advisory, each Fund pays all other costs and expenses of its operations and a
portion of Nuveen Insured Tax-Free Bond Fund'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. Founded in 1898, Nuveen is the
oldest and largest investment banking firm specializing in the underwriting and
distribution of tax-exempt securities and maintains the largest research de-
partment in the investment banking community devoted exclusively to the analy-
sis of municipal securities. In 1961, Nuveen began sponsoring the Nuveen Tax-
Exempt Unit Trust and since that time has issued more than $36 billion in tax-
exempt unit trusts, including over $12 billion in tax-exempt insured unit
trusts. In addition, Nuveen open-end and closed-end funds held approximately
$31 billion in tax-exempt securities under management as of the date of this
Statement. Over 1,000,000 individuals have invested to date in Nuveen's tax-ex-
empt funds and trusts. Nuveen is a subsidiary of The John Nuveen Company which,
in turn, is approximately 80% owned by The St. Paul     
Companies, Inc. ("St. Paul"). St. Paul is located in St. Paul, Minnesota, and
is principally engaged in providing property-liability insurance through sub-
sidiaries.
   
Nuveen Advisory's portfolio managers call upon the resources of Nuveen's Re-
search Department, the largest in the investment banking industry devoted ex-
clusively to tax-exempt securities. Nuveen's Research Department was selected
in 1994 by Research & Ratings Review, a municipal industry publication, as one
of the leading research teams in the municipal industry, based on an extensive
industry-wide poll of portfolio managers, department heads and bond buyers. The
Nuveen Research Department reviews more than $100 billion in tax-exempt bonds
every year.     
 
The Funds, the other Nuveen funds, Nuveen Advisory, and other related entities
have adopted a code of ethics which essentially prohibits all Nuveen fund man-
agement personnel, including Nuveen fund portfolio managers, from engaging in
personal investments which compete or interfere with, or attempt to take advan-
tage of, a Fund's anticipated or actual portfolio transactions, and is designed
to assure that the interest of Fund shareholders are placed before the interest
of Nuveen personnel in connection with personal investment transactions.
 
                                                                              47
<PAGE>
 
                             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 ob-
tained elsewhere. Portfolio securities will not be purchased from Nuveen or its
affiliates except in compliance with the Investment Company Act of 1940.
 
The Funds expect that all portfolio transactions will be effected on a princi-
pal (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 deal-
ers which, in addition, furnish research information (primarily credit analyses
of issuers and general economic reports) and statistical and other services to
Nuveen Advisory. It is not possible to place a dollar value on information and
statistical and other services received from dealers. Since it is only supple-
mentary to Nuveen Advisory's own research efforts, the receipt of research in-
formation is not expected to reduce significantly Nuveen Advisory's expenses.
While Nuveen Advisory will be primarily responsible for the placement of the
business of the 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 Directors.
 
Nuveen Advisory reserves the right to, and does, manage other investment ac-
counts and investment companies for other clients, which may have investment
objectives similar to the 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 securi-
ties 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 com-
parable 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 recom-
mending investments to the Fund and such other clients. While this procedure
could have a detrimental effect on the price or amount of the securities avail-
able to a Fund from time to time, it is the opinion of the Board of Directors
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 Munici-
pal 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 in-
vested in a particular issue. In addition, purchases of securities made pursu-
ant to the terms of the Rule must be approved at least quarterly by the Board
of Directors, including a majority of the directors who are not interested per-
sons of the Funds.

                                NET ASSET VALUE
   
As stated in the Prospectus, the net asset value of the shares of each Fund
will be determined separately for each class of a Fund's shares by The Chase
Manhattan Bank, N.A., the Funds' Custodian, as of 4:00 p.m. Eastern Time on
each day on which the New York Stock Exchange (the "Exchange") is normally open
for trading. The Exchange is not open for trading on New Year's Day, Washing-
ton's Birthday, Good Friday, Memorial Day, Independence Day, Labor Day, Thanks-
giving 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 liabilities attributable to the class, by the
number of shares of the class outstanding.     
 
In determining net asset value for each of the Funds, the Funds' custodian
utilizes the valuations of portfolio securities furnished by a pricing service
approved by the directors. The pricing service values portfolio securities at
the mean between the quoted bid and asked price or the yield equivalent when
quotations are readily available. Securities for which quotations are not read-
ily available (which constitute a majority of the securities held by these
Funds) are valued at fair value as determined by the pricing service using
methods which include consideration of the following: yields or prices of mu-
nicipal bonds of comparable quality, type of issue, coupon, maturity and rat-
ing; indications as to value from dealers; and general market conditions. The
pricing service may employ electronic data processing techniques and/or a ma-
trix system to determine valuations. The procedures of the pricing service and
its valuations are reviewed by the officers of the Funds under the general su-
pervision of the Board of Directors.
 
                                  TAX MATTERS
 
FEDERAL INCOME TAX MATTERS
 
The following discussion of federal income tax matters is based upon the advice
of Fried, Frank, Harris, Shriver & Jacobson, Washington, D.C., counsel to the
Funds.
 
As described in the Prospectus, each Fund intends to qualify, as it has in
prior years, 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 as-
sets, and distributions of its income to shareholders. First, a Fund must de-
rive 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) de-
rived with respect to its business of investing in such stock or securities
(the "90% gross income test"). Second, a Fund must derive less than 30% of its
annual gross income from the sale or other disposition of any of the following
which was held for less than three months: (i) stock or securities and (ii)
certain options, futures, or forward contracts (the "short-short test"). Third,
a Fund must diversify its holdings so that, at the close of each quarter of its
taxable year, (i) at least 50% of the value of its total assets is comprised of
cash, cash items, United States Government securities, securities of other reg-
ulated 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
 
                                                                              49
<PAGE>
 
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 secu-
rities 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 in-
terest, 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 in-
terest (the excess of its gross tax-exempt interest income over certain disal-
lowed 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 invest-
ment 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 pur-
poses, the tax basis of shares owned by a shareholder of the Fund will be in-
creased by an amount equal under current law to 65% of the amount of undistrib-
uted capital gains included in the shareholder's gross income. Each Fund in-
tends to distribute at least annually to its shareholders all or substantially
all of its net tax-exempt interest and any investment company taxable income
and net capital gain.     
 
Treasury regulations permit a regulated investment company, in determining its
investment company taxable income and net capital gain, i.e., the excess of net
long-term capital gain over net short-term capital loss for any taxable year,
to elect (unless it has made a taxable year election for excise tax purposes as
discussed below) to treat all or part of any net capital loss, any net long-
term capital loss or any net foreign currency loss incurred after October 31 as
if they had been incurred in the succeeding year.
 
Each Fund also intends to satisfy conditions (including requirements as to the
proportion of its assets invested in Municipal Obligations) that will enable it
to designate distributions from the interest income generated by investments in
Municipal Obligations, which are exempt from regular federal income tax when
received by such Fund, as exempt-interest dividends. Shareholders receiving ex-
empt-interest dividends will not be subject to regular federal income tax on
the amount of such dividends. Insurance proceeds received by a Fund under any
insurance policies in respect of scheduled interest payments on defaulted Mu-
nicipal Obligations will be excludable from federal gross income under Section
103(a) of the Code. In the case of non-appropriation by a political subdivi-
sion, however, there can be no assurance that payments made by the insurer rep-
resenting interest on "non-appropriation" lease obligations will be excludable
from gross income for federal income tax purposes. See "Fundamental Policies
and Investment Portfolio--Portfolio Securities."

<PAGE>
 
Distributions by each Fund of net interest received from certain taxable tempo-
rary investments (such as certificates of deposit, commercial paper and obliga-
tions of the United States 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./1/ 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 ex-
ceed the market discount, and any gain realized in excess of the market dis-
count will be treated as capital gains. Any net long-term capital gains real-
ized by a Fund and distributed to shareholders in cash or in 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 ex-
cess will be treated as gain from the sale of his or her shares, as discussed
below.
 
If any of the Funds engages in hedging transactions involving financial futures
and options, these transactions will be subject to special tax rules, the ef-
fect 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 each Fund's investment income consists primarily
of interest, none of its dividends, whether or not treated as exempt-interest
dividends, is expected to qualify under the Internal Revenue Code for the divi-
dends received deductions for corporations.
 
Prior to purchasing shares in one of the Funds, the impact of dividends or dis-
tributions which are expected to be or have been declared, but not paid, should
be carefully considered. Any dividend or distribution declared shortly after a
purchase of such shares prior to the record date will have the effect of reduc-
ing the per share net asset value by the per share amount of the dividend or
distribution.
 
Although dividends generally will be treated as distributed when paid, divi-
dends declared in October, November or December, payable to shareholders of
record on a specified date in one of those months and paid during the following
January, will be treated as having been distributed by each Fund (and received
by the shareholders) on December 31.
 
The redemption or exchange of the shares of a Fund normally will result in cap-
ital gain or loss to the shareholders. Generally, a shareholder's gain or loss
will be long-term gain or loss if the shares have
been held for more than one year. Present law taxes both long- and short-term
capital gains of corpora-

/1/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 in-
   come and designate the use of such method within 60 days after the end of
   the Fund's taxable year. Under this method, one designated percentage is ap-
   plied uniformly to all distributions made during the Fund's taxable year.
   The percentage of income designated as tax-exempt for any particular distri-
   bution may be substantially different from the percentage of the Fund's in-
   come that was tax-exempt during the period covered by the distribution.
 
                                                                              51

tions at the rates applicable to ordinary income. For non-corporate taxpayers,
however, net capital gains (i.e., the excess of net long-term capital gain over
net short-term capital loss) will be taxed at a maximum marginal rate of 28%,
while short-term capital gains and other ordinary income will be taxed at a
maximum marginal rate of 39.6%. Because of the limitations on itemized deduc-
tions and the deduction for personal exemptions applicable to higher income
taxpayers, the effective rate of tax may be higher in certain circumstances.
 
All or a portion of a sales load 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 load pursuant to the reinvestment or exchange privilege. Any disregarded
portion of such load will result in an increase in the shareholder's tax basis
in the shares subsequently acquired. Moreover, losses recognized by a share-
holder 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 divi-
dends 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 gain 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 share-
holder purchases other shares of such Fund (whether through reinvestment of
distributions or otherwise) or the shareholder acquires or enters into a con-
tract 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 re-
flected 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, each Fund must distribute or be
deemed to have distributed by December 31 of each calendar year at least 98% of
its taxable ordinary income for such year, at least 98% of the excess of its
realized capital gains over its realized capital losses (generally computed on
the basis of the one-year period ending on October 31 of such year) and 100% of
any taxable ordinary income and the excess of realized capital gains over real-
ized capital losses for the prior year that was not distributed during such
year and on which such Fund paid no federal income tax. For purposes of the ex-
cise tax, a regulated investment company may reduce its capital gain net income
(but not below its net capital gain) by the amount of any net ordinary loss for
the calendar year in determining the amount of ordinary taxable income for the
current calendar year (and, instead, include such gains and losses in determin-
ing ordinary taxable income for the succeeding calendar year). The Funds intend
to make timely distributions in compliance with these requirements and conse-
quently it is anticipated that they generally will not be required to pay the
excise tax.     
 
52
<PAGE>
 
If in any year a Fund should fail to qualify under Subchapter M for tax treat-
ment as a regulated investment company, the Fund would incur a regular corpo-
rate federal income tax upon its income for that year (other than interest in-
come from Municipal Obligations), and distributions to its shareholders would
be taxable to shareholders as ordinary dividend income for federal income tax
purposes to the extent of the Fund's available earnings and profits.
 
Among the requirements that a Fund must meet in order to qualify under
Subchapter M in any year is that less than 30% of its gross income must be de-
rived from the sale or other disposition of securities and certain other assets
held for less than three months.
 
Because the Funds may invest in private activity bonds, the interest on which
is not federally tax-exempt to persons who are "substantial users" of the fa-
cilities financed by such bonds or "related persons" of such "substantial us-
ers," 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 ad-
visers before investing in one of the Funds.
 
Federal tax law imposes an alternative minimum tax with respect to both corpo-
rations and individuals. Interest on certain Municipal Obligations, such as
bonds issued to make loans for housing purposes or to private entities (but not
for certain tax-exempt organizations such as universities and non-profit hospi-
tals), 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 re-
ceives income from Municipal Obligations subject to the alternative minimum
tax, a portion of the dividends paid by it, although otherwise exempt from fed-
eral income tax, is taxable to shareholders to the extent that their tax lia-
bility 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 in-
creased by 75% of the difference between an alternative measure of income ("ad-
justed current earnings") and the amount otherwise determined to be the alter-
native 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 the Fund, will
be added to the taxable income of individuals receiving social security or
railroad retirement benefits in determining whether a portion of that benefit
will be subject to federal income tax.
 
The Code provides that interest on indebtedness incurred or continued to pur-
chase or carry shares of 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.
 
                                                                              53

The Funds are required in certain circumstances to withhold 31% of taxable div-
idends 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 certifi-
cations, or who are otherwise subject to back-up withholding.
 
The foregoing is a general and abbreviated summary of the provisions of the
Code and Treasury Regulations presently in effect as they directly govern the
taxation of the Funds and their shareholders. For complete provisions, refer-
ence should be made to the pertinent Code sections and Treasury Regulations.
The Code and Treasury Regulations are subject to change by legislative or ad-
ministrative 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 following state tax information applicable to each Fund or its respective
shareholders is based upon the advice of Edwards & Angell, special state tax
counsel to each Fund, and represents a summary of certain provisions of each
state's tax laws presently in effect. The state tax information below assumes
that each Fund qualifies as a regulated investment company for federal income
tax purposes under Subchapter M of the Code, and that amounts so designated by
each Fund to its shareholders qualify as "exempt-interest dividends" under Sec-
tion 852(b)(5) of the Code. These state tax provisions are subject to change by
legislative or administrative action, which may be applied retroactively to
Fund transactions. You should consult your own tax adviser for more detailed
information concerning state taxes to which you may be subject.
 
NUVEEN MASSACHUSETTS INSURED TAX-FREE VALUE FUND
Individual shareholders of the Massachusetts Fund who are subject to Massachu-
setts income taxation will not be required to include that portion of their
federally tax-exempt dividends in Massachusetts gross income which the Massa-
chusetts Fund clearly identifies as directly attributable to interest earned on
Municipal Obligations issued by governmental authorities in Massachusetts and
which are specifically exempted from income taxation in Massachusetts; provided
that such portion is identified in a written notice mailed to the shareholders
of the Massachusetts Fund not later than sixty days after the close of the Mas-
sachusetts Fund's tax year. Also, the individual shareholders of the Massachu-
setts Fund will not be required to include in gross income interest earned on
obligations of United States possessions and territories to the extent interest
earned on such obligations is exempt from taxation by the states pursuant to
federal law.
Similarly, such shareholders will not be required to include in Massachusetts
gross income capital gain dividends designated by the Massachusetts Fund to the
extent such dividends are attributable to gains derived from Municipal Obliga-
tions issued by Massachusetts governmental authorities and are specifically ex-
empted from income taxation in Massachusetts, provided that such dividends are
identified in a written notice mailed to the shareholders of the Massachusetts
Fund not later than sixty days after the close of the Massachusetts Fund's tax
year. Lastly, any dividends of the Massachusetts Fund attributable
 
54
<PAGE>
 
to interest on U.S. obligations exempt from state taxation and included in
Federal gross income will not be included in Massachusetts gross income if
identified by the Massachusetts Fund in a written notice mailed to sharehold-
ers within sixty days after the close of the Massachusetts Fund's tax year.
Massachusetts shareholders will be required to include all remaining dividends
in their Massachusetts income.
 
To the extent not otherwise exempted from Massachusetts income taxation as
provided above, the Massachusetts Fund's long-term capital gains for federal
income tax purposes will be taxed as long-term capital gains to the individual
shareholders of the Massachusetts Fund for purposes of Massachusetts income
taxation. Massachusetts shareholders will be required to recognize any taxable
gain or loss that is recognized for federal income tax purposes upon an ex-
change or redemption of their shares.
 
If a shareholder of the Massachusetts Fund is a Massachusetts business corpo-
ration or any foreign business corporation which exercises its charter, quali-
fies to do business, actually does business or owns or uses any part of its
capital, plant or other property in Massachusetts, then it will be subject to
Massachusetts excise taxation either as a tangible property corporation or as
an intangible property corporation. If the corporate shareholder is a tangible
property corporation, it will be taxed upon its net income allocated to Massa-
chusetts and the value of certain tangible property. If it is an intangible
property corporation, it will be taxed upon its net income and net worth allo-
cated to Massachusetts. Net income is gross income less allowable deductions
for federal income tax purposes, subject to specified modifications. Dividends
received from the Massachusetts Fund are includable in gross income and gener-
ally may not be deducted by a corporate shareholder in computing its net in-
come. The corporation's shares in the Massachusetts Fund are not includable in
the computation of the tangible property base of a tangible property corpora-
tion, but are includable in the computation of the net worth base of an intan-
gible property corporation.
 
Shares of the Massachusetts Fund will be includable in the Massachusetts gross
estate of a deceased individual shareholder who is a resident of Massachusetts
for purposes of the Massachusetts Estate Tax.
 
Shares of the Massachusetts Fund will be exempt from local property taxes in
Massachusetts.
 
NUVEEN NEW YORK TAX-FREE VALUE FUND
Individual shareholders of the New York Fund who are subject to New York State
(or New York City) personal income taxation will not be required to include in
their New York adjusted gross income that portion of their exempt-interest
dividends (as determined for federal income tax purposes) which the New York
Fund clearly identifies as directly attributable to interest earned on Munici-
pal Obligations issued by governmental authorities in New York ("New York Mu-
nicipal Obligations") and which are specifically exempted from personal income
taxation in New York State (or New York City), or interest earned on obliga-
tions of United States possessions or territories to the extent interest
earned on such obligations is exempt from taxation by the states pursuant to
federal law. Distributions to individual shareholders of dividends derived
from interest that does not qualify as an exempt-interest dividend (as deter-
mined for federal income tax purposes), distributions of exempt-interest divi-
dends (as determined for federal income tax purposes) which are derived from
interest earned on Municipal Obligations issued by governmental authorities in
states other than New York State, and distributions derived from inter-
 
                                                                             55

est earned on federal obligations will be included in their New York adjusted
gross income as ordinary income.
 
Distributions to individual shareholders of the New York Fund of capital gain
dividends (as determined for federal income tax purposes) will be included in
their New York adjusted gross income as long-term capital gains. Distributions
to individual shareholders of the New York Fund of dividends derived from any
net income received from taxable temporary investments and any net short-term
capital gains realized by the New York Fund will be included in their New York
adjusted gross income as ordinary income. Present New York law taxes long-term
capital gains at the rates applicable to ordinary income.
 
Gain or loss, if any, resulting from an exchange or redemption of shares of the
New York Fund that is recognized by individual shareholders of the New York
Fund for federal income tax purposes will be recognized for purposes of New
York State (or New York City) personal income taxation.
 
Generally, corporate shareholders of the New York Fund which are subject to New
York State franchise taxation (or New York City general corporation taxation)
will be taxed upon their entire net income, business and investment capital, or
at a flat rate minimum tax. Entire income will include dividends received from
the New York Fund (as determined for federal income tax purposes), as well as
any gain or loss recognized from an exchange or redemption of shares of the New
York Fund that is recognized for federal income tax purposes. Investment capi-
tal will include the corporate shareholder's shares of the New York Fund. Cor-
porate shareholders of the New York Fund, which are subject to the temporary
metropolitan transportation surcharge, will be required to pay a tax surcharge
on the franchise taxes imposed by New York State.
 
Shareholders of the New York Fund will not be subject to New York City unincor-
porated business taxation solely by reason of their ownership of shares of the
New York Fund. If a shareholder of the New York Fund is subject to the New York
City unincorporated business tax, income and gains derived from the New York
Fund will be subject to such tax, except for exempt-interest dividends (as de-
termined for federal income tax purposes) which the New York Fund clearly iden-
tifies as directly attributable to interest earned on New York Municipal Obli-
gations.
 
Shares of the New York Fund will be exempt from local property taxes in New
York State and New York City, but will be includible in the New York gross es-
tate of a deceased individual shareholder who is a resident of New York for
purposes of the New York Estate Tax.
 
                            PERFORMANCE INFORMATION
 
As explained in the Prospectus, 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 invest-
ment income per share earned during the
 
56
<PAGE>
 
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:
 
<TABLE>
 <C>   <C> <C>             <C> <S>
 Yield =   2[(a-b+1)/6/-1]
</TABLE>
     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 sales charge of 4.50%.
   
In computing yield, the Funds follow certain standardized accounting practices
specified by SEC rules. These practices are not necessarily consistent with
those that the Funds use to prepare their annual and interim financial state-
ments 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. Yield for each class of shares of each Fund as of
February 29, 1996 are set forth below.     
   
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 in-
come 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 ended February 29,
1996, quoted in the left-hand column.

Each Fund may from time to time in its sales materials report a quotation of
the current distribution rate. The distribution rate represents a measure of
dividends distributed for a specified period. Distribution rate is computed by
taking the most recent monthly tax-free income dividend per share, multiplying
it by 12 to annualize it, and dividing by the appropriate price per share
(e.g., net asset value for purchases to be made without a load such as rein-
vestments from Nuveen UITs, or the maximum public offering price). The distri-
bution rate differs from yield and total return and therefore is not intended
to be a complete measure of performance. Distribution rate may sometimes be
higher than yield because it may not include the effect of amortization of bond
premiums to the extent such premiums arise after the bonds were purchased. The
distribution rates as of February 29, 1996, based on the maximum public offer-
ing price then in effect for the Funds were as follows:

 *Assumes imposition of the maximum sales charge for Class A shares of 4.50%.
   
Average annual total return quotation is computed in accordance with a stan-
dardized method prescribed by SEC rules. The average annual total return for a
specific period is found by taking a hypothetical, $1,000 investment ("initial
investment") in Fund shares on the first day of the period, reducing the amount
to reflect the maximum sales charge, and computing the "redeemable value" of
that investment at the end of the period. The redeemable value is then divided
by the initial investment, and this quotient is taken to the Nth root (N repre-
senting the number of years in the period) and 1 is subtracted from the result,
which is then expressed as a percentage. The calculation assumes that all in-
come and capital gains distributions have been reinvested in Fund shares at net
asset value on the reinvestment dates during the period. The average annual to-
tal return figures, including the effect of the current maximum sales charge
for the Class A Shares, for the one- and five-year periods ended February 29,
1996, and for the period from inception (on December 10, 1986 with respect to

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

Calculation of taxable equivalent total return is also not subject to a pre-
scribed formula. Taxable equivalent total return for a specific period is cal-
culated by first taking a hypothetical initial investment in Fund shares on the
first day of the period, computing the total return for each calendar year in
the period in the manner described above, and increasing the total return for
each such calendar year by the amount of additional income that a taxable fund
would need to have generated to equal the income on an after-tax basis, at a
specified income tax rate (usually the highest marginal federal tax rate), cal-
culated as described above under the discussion of "taxable equivalent yield."
The resulting amount for the calendar year is then divided by the initial in-
vestment amount to arrive at a "taxable equivalent total return factor" for the
calendar year. The taxable equivalent total return factors for all the calendar
years are then multiplied together and the result is then annualized by taking
its Nth root (N representing the number of years in the period) and subtracting
1, which provides a taxable equivalent total return expressed as a percentage.
Using the 39.6% maximum marginal federal tax rate for 1996, the annual taxable
equivalent total returns for each Fund's Shares for the one- and five-year pe-
riods ended February

From time to time, a Fund may compare its risk-adjusted performance with other
investments that may provide different levels of risk and return. For example,
a Fund may compare its risk level, as measured by the variability of its peri-
odic returns, or its RISK-ADJUSTED TOTAL RETURN, with those of other funds or
groups of funds. Risk-adjusted total return would be calculated by adjusting
each investment's total return to account for the risk level of the investment.
 
A Fund may also compare its TAX-ADJUSTED TOTAL RETURN with that of other funds
or groups of funds. This measure would take into account the tax-exempt nature
of exempt-interest dividends and the payment of income taxes on a fund's dis-
tributions of net realized capital gains and ordinary income.
   
The risk level for a class of shares of a Fund, and any of the other invest-
ments used for comparison, would be evaluated by measuring the variability of
the investment's return, as indicated by the annualized standard deviation of
the investment's monthly returns over a specified measurement period (e.g.,
three years). An investment with a higher annualized STANDARD DEVIATION OF
MONTHLY RETURNS would indicate that a fund had greater price variability, and
therefore greater risk, than an investment with a lower annualized standard de-
viation.     
 
                                                                              61

The annualized standard deviation of monthly returns for the three years ended

THE RISK-ADJUSTED TOTAL RETURN for a class of shares of a Fund and for other
investments over a specified period would be evaluated by dividing (a) the re-
mainder of the investment's annualized three-year total return minus the
annualized total return of an investment in short-term tax-exempt securities
(essentially a risk-free return) over that period, by (b) the annualized stan-
dard deviation of the investment's monthly returns for the period. This ratio
is sometimes referred to as the "Sharpe measure" of return. An investment with
a higher Sharpe measure would be regarded as producing a higher return for the
amount of risk assumed during the measurement period than an investment with a
lower Sharpe measure. The Sharpe measure for the three-year period ended Febru-
ary 29, 1996, for the Class R Shares of each of the Funds, was as follows:

Class A Shares of the Funds are sold at net asset value plus a current maximum
sales charge of 4.50% of the offering price. This current maximum sales charge
will typically be used for purposes of calculating performance figures. Yield,
returns and net asset value of each class of shares of the Funds will fluctu-
ate. Factors affecting the performance of the Funds include general market con-
ditions, operating expenses and investment management fees. 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 Compa-
nies 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 perfor-
mance figures. Any given performance quotation or performance comparison should
not be considered as representative of the performance of the Funds for any fu-
ture period.

There are differences and similarities between the investments which the Funds
may purchase and the investments measured by the indexes and reporting serv-
ices 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 vari-
ous market conditions. The Lehman Brothers Municipal Bond Index is an unman-
aged index that generally represents the performance of high grade intermedi-
ate and long-term municipal bonds during various market conditions. 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 Obli-
gations in pursuing their objective of as high a level of current interest in-
come 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 secu-
rities funds, corporate bond funds (either investment grade or high yield), or
Ginnie Mae funds. These types of funds, because of the character of their un-
derlying securities, differ from municipal bond funds in several respects. The
susceptibility of the price of treasury bonds to credit risk is far less than
that of municipal bonds, but the price of treasury bonds tends to be slightly
more susceptible to change resulting from changes in market interest rates.
The susceptibility of the price of investment grade corporate bonds and munic-
ipal bonds to market interest rate changes and general credit changes is simi-
lar. High yield bonds are subject to a greater degree of price volatility than
municipal bonds resulting from changes in market interest rates and are par-
ticularly 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 in-
stallments 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 in-
terest 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 of the sensitivity of Ginnie Mae prepayment expe-
rience to change in interest rates.
 
      ADDITIONAL INFORMATION ON THE PURCHASEAND REDEMPTION OF FUND SHARES
   
As described in the Prospectus, each Fund has adopted a Flexible Pricing Pro-
gram which provides you with alternative ways of purchasing Fund shares based
upon your individual investment needs and preferences. You may purchase Class
A Shares at a price equal to their net asset value plus an up-front sales
charge.     
 
For information regarding the up-front sales charge on Class A shares, see the
table under "How to Buy Fund Shares" of the Prospectus. Set forth is an exam-
ple of the method of computing the offering price
 
                                                                             63

of the Class A shares of each of the Funds. The example assumes a purchase on
February 29, 1996 of Class A shares from the National Fund aggregating less
than $50,000 subject to the schedule of sales charges set forth in the Prospec-
tus at a price based upon the net asset value of the Class A shares.

You may purchase Class C Shares without any up-front sales charge at a price
equal to their net asset value, but subject to an annual distribution fee de-
signed to compensate Authorized Dealers over time for the sale of Fund shares.
Class C Shares are subject to a contingent deferred sales charge for redemption
within 12 months of purchase. Class C Shares automatically convert to Class A
Shares six years after purchase. Both Class A Shares and Class C Shares are
subject to annual service fees, which are used to compensate Authorized Dealers
for providing you with ongoing account services.     
   
Under the Flexible Pricing Program, all Fund shares outstanding as of September
6, 1994, have been designated as Class R Shares. Class R Shares are available
for purchase at a price equal to their net asset value only under certain lim-
ited circumstances, or by specified investors, as described herein.     
   
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 dis-
tribution or service plan applicable to its shares. In addition, the Class C
Shares are subject to a conversion feature, as described below. As a result of
the differences in the expenses borne by each class of shares, net income per
share, dividends per share and net asset value per share will vary among 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 distri-
bution and service fees.     
 
Each Fund has special purchase programs under which certain persons may pur-
chase Class A Shares at reduced sales charges. One such program is available to
members of a "qualified group."
 
An individual who is a member of a "qualified group" may purchase Class A
Shares of a Fund (or any other Nuveen Fund with respect to which a sales charge
is imposed), at the reduced sales charge applicable to the group taken as a
whole. A "qualified group" is one which (i) has been in existence for more than
six months; (ii) has a purpose other than investment; (iii) has five or more
participating members; (iv) has agreed to include sales literature and other
materials related to the Fund in publications and mailings to members; (v) has
agreed to have its group administrator submit a single bulk order and make pay-
ment with a single remittance for all investments in the Fund during each in-
vestment period by all participants who choose to invest in the Fund; and (vi)
has agreed to provide the Fund's transfer
 
64
<PAGE>
 
agent with appropriate backup data for each participant of the group in a for-
mat fully compatible with the transfer agent's processing system.
 
The "amount" of a share purchase by a participant in a group purchase program
for purposes of determining the applicable sales charge is (i) the aggregate
value of all shares of the Fund (and all other Nuveen Funds with respect to
which a sales charge is imposed) currently held by participants of the group,
plus (ii) the amount of shares currently being purchased.
   
Special Sales Charge Waivers. Class A Shares of the Funds may be purchased at
net asset value without a sales charge, and Class R Shares may be purchased,
by the following categories of investors:     
   
 .  officers, directors and retired directors of the Fund;     
   
 .  bona fide, full-time and retired employees of Nuveen or its affiliates, any
   parent company of Nuveen, and subsidiaries thereof, or their immediate fam-
   ily members (as defined below);     
   
 .  any person who, for at least 90 days, has been an officer, director or bona
   fide employee of any Authorized Dealer, or their immediate family members;
          
 .  officers and directors of bank holding companies that make Fund shares
   available directly or through subsidiaries or bank affiliates;     
   
 .  bank or broker-affiliated trust departments investing funds over which they
   exercise exclusive discretionary investment authority and that are held in
   a fiduciary, agency, advisory, custodial or similar capacity;     
   
 .  investors purchasing through a mutual fund purchase program sponsored by a
   broker-dealer that offers a selected group of mutual funds either without a
   transaction fee or with an asset-based fee or a fixed fee that does not
   vary with the amount of the purchase. In order to qualify, such purchase
   program must offer a full range of mutual fund related services and share-
   holder account servicing capabilities, including establishment and mainte-
   nance of shareholder accounts, addressing investor inquiries regarding ac-
   count activity and investment performances, processing of trading and divi-
   dend activity and generation of monthly account statements and year-end tax
   reporting; and     
   
 .  registered investment advisers, certified financial planners and registered
   broker-dealers who in each case either charge periodic fees to their cus-
   tomers for financial planning, investment advisory or asset management
   services, or provide such services in connection with the establishment of
   an investment account for which a comprehensive "wrap fee" charge is im-
   posed.     
 
The Funds may encourage registered representatives and their firms to help ap-
portion their assets among bonds, stocks and cash, and may seek to participate
in programs that recommend a portion of their assets be invested in tax-free,
fixed income securities.
 
To help advisers and investors better understand and most efficiently use the
Funds to reach their investment goals, the Funds may advertise and create spe-
cific investment programs and systems. For example, this may include informa-
tion on how to use the Funds to accumulate assets for future education needs
or periodic payments such as insurance premiums. The Funds may produce soft-
ware or additional sales literature to promote the advantages of using the
Funds to meet these and other specific investor needs.
 
                                                                             65

Exchange 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 avail-
able for public purchase. Shares of the Nuveen money market funds may be pur-
chased 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 Veter-
ans Day.
 
For more information on the procedure for purchasing shares of the Funds and on
the special purchase programs available thereunder, see "How to Buy Fund
Shares" in the Prospectus.
   
Nuveen serves as the principal underwriter of the shares of each of the Funds
pursuant to a "best efforts" arrangement as provided by a distribution agree-
ment with the Nuveen Insured Tax-Free Bond Fund, Inc., dated April 27, 1992 and
last renewed on July 27, 1995 ("Distribution Agreement"). Pursuant to the Dis-
tribution Agreement, the Nuveen Insured Tax-Free Bond Fund, Inc. appointed
Nuveen to be its agent for the distribution of the Funds' shares on a continu-
ous offering basis. Nuveen sells shares to or through brokers, dealers, banks
or other qualified financial intermediaries (collectively referred to as "Deal-
ers"), or others, in a manner consistent with the then effective registration
statement of the Nuveen Insured Tax-Free Bond Fund, Inc. Pursuant to the Dis-
tribution 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 liter-
ature, 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 Nuveen Insured Tax-Free Bond Fund, Inc. pur-
suant to Rule 12b-1 and described herein under "Distribution and Service Plan."
Nuveen receives any CDSCs imposed on redemptions of Class C Shares redeemed
within 12 months of purchase, but any such amounts as to which a reinstatement
privilege is not exercised are set off against and reduce amounts otherwise
payable to Nuveen pursuant to the distribution plan. Nuveen also receives any
CDSCs imposed on redemptions of certain Class A Shares redeemed within 18
months of purchase.     
 
The 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 for each of the Funds for the last three fiscal years. All figures are
to the nearest thousand.

                       DISTRIBUTION AND SERVICE PLAN     
 
Each Fund has adopted a plan (the "Plan") pursuant to Rule 12b-1 under the In-
vestment Company Act of 1940, which provides that Class C Shares will be sub-
ject to an annual distribution fee, and that both Class A Shares and Class C
Shares will be subject to an annual service fee. Class R Shares will not be
subject to either distribution or service fees.
 
The distribution fee applicable to Class C Shares under each Fund's Plan will
be payable to reimburse Nuveen for services and expenses incurred in connection
with the distribution of Class C Shares. These expenses include payments to Au-
thorized Dealers, including Nuveen, who are brokers of record with respect to
the Class C Shares, as well as, without limitation, expenses of printing and
distributing prospectuses to persons other than shareholders of the Fund, ex-
penses of preparing, printing and distributing advertising and sales literature
and reports to shareholders used in connection with the sale of
Class C Shares, certain other expenses associated with the distribution of
Class C Shares, and any distribution-related expenses that may be authorized
from time to time by the Board of Directors.
 
The service fee applicable to Class A Shares and Class C Shares under each
Fund's Plan will be payable to Authorized Dealers in connection with the provi-
sion of ongoing account services to shareholders. These services may include
establishing and maintaining shareholder accounts, answering shareholder inqui-
ries and providing other personal services to shareholders.
   
Each Fund may spend up to .25 of 1% per year of the average daily net assets of
Class A Shares as a service fee under the Plan applicable to Class A Shares.
Each Fund may spend up to .75 of 1% per year of the average daily net assets of
Class C Shares as a distribution fee and up to .25 of 1% per year of the aver-
age daily net assets of Class C Shares as a service fee under the Plan applica-
ble to Class C Shares. The .75 of 1% distribution fee will be reduced by the
amount of any CDSC imposed on the redemption of Class C Shares within 12 months
of purchase as to which a reinstatement privilege has not been exercised. For
the fiscal year ended February 29, 1996, 100% of service fees and distribution
fees were paid out as compensation to Authorized Dealers. The amount of compen-
sation paid to Authorized Dealers for the fiscal year ended February 29, 1996
for each Fund per class of shares was as follows:

Under each Fund's Plan, the Fund will report quarterly to the Board of Direc-
tors for its review of all amounts expended per class of shares under the Plan.
The Plan may be terminated at any time with respect to any class of shares,
without the payment of any penalty, by a vote of a majority of the directors
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 securi-
ties of such class. The Plan may be renewed from year to year if approved by a
vote of the Board of Directors and a vote of the non-interested directors who
have no direct or indirect financial interest in the Plan cast in person at a
meeting called for the purpose of voting on the Plan. The Plan may be continued
only if the directors who vote to approve such continuance conclude, in the ex-
ercise 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 directors
by a vote cast in person at a meeting called for the purpose of considering
such amendments. During the continuance of the Plan, the selection and nomina-
tion of the non-interested directors of the Fund will be committed to the dis-
cretion of the non-interested directors then in office.

Dear
shareholder

[PHOTO OF RICHARD J. FRANKE APPEARS HERE]

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

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

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

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


                                       3

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

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

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

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

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

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

Sincerely,


/s/ Richard J. Franke

Answering your
questions



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

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

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

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

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

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


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

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

                                       6

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

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

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



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


What is Nuveen's market outlook for 1996?

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

</TABLE>

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

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

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


* One-year, 5-year and 10-year total return figures for Class R Shares are not
representative for Class A Shares or Class C Shares because they do not take
into account (1) the difference between the maximum front-end sales charge
applicable to Class R Shares (none), Class A Shares (4.50%) and Class C Shares
(none); (2) the .25% annual 12b-1 service fee applicable to Class A and Class C
Shares; (3) the .75% annual 12b-1 distribution fee to be deducted from income
with respect to Class C Shares; and (4) other class-level expenses applicable to
Class A Shares and Class C Shares.

** Maximum public offering price, which includes sales charges, which are
reduced for purchases over $50,000 and waived for reinvestment of dividends.

+ Life of class; Class A Shares and Class C Shares were first issued on June 13,
1995.

The Lehman Municipal Bond Index is comprised of a broad range of investment-
grade municipal bonds, and does not reflect any initial or ongoing expenses. The
Nuveen fund return depicted in the chart reflects the initial maximum sales
charge applicable to R Shares at the time (4.75%) and all ongoing fund expenses.

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

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

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


* One-year, 5-year and life of fund total return figures for Class R Shares are
not representative for Class A Shares or Class C Shares because they do not take
into account (1) the difference between the maximum front-end sales charge
applicable to Class R Shares (none), Class A Shares (4.50%) and Class C Shares
(none); (2) the .25% annual 12b-1 service fee applicable to Class A and Class C
Shares; (3) the .75% annual 12b-1 distribution fee to be deducted from income
with respect to Class C Shares; and (4) other class-level expenses applicable to
Class A Shares and Class C Shares.
** Maximum public offering price, which includes sales charges, which are
reduced for purchases over $50,000 and waived for reinvestment of dividends.
+ Life of class; Class A Shares and Class C Shares were first issued at
different times after September 6, 1994.

The Lehman Municipal Bond Index is comprised of a broad range of investment-
grade municipal bonds, and does not reflect any initial or ongoing expenses. The
Nuveen fund return depicted in the chart reflects the initial maximum sales
charge applicable to R Shares at the time (4.75%) and all ongoing fund expenses.

                                                               FEBRUARY 29, 1996


1. GENERAL INFORMATION AND SIGNIFICANT
ACCOUNTING POLICIES

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

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

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

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

Securities valuation

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

Securities transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may be settled a month or more after the transaction date. Any securities so
purchased are subject to market fluctuation during this period. The Funds have
instructed the custodian to segregate assets in a separate account with a
current value at least equal to the amount of their purchase commitments. At
February 29, 1996, Insured Municipal Bond had purchase commitments of
$6,032,048. Municipal Bond had no such purchase commitments.

NOTES TO FINANCIAL STATEMENTS
 
Interest income

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt securities
when required for federal income tax purposes.

Dividends and distributions to shareholders

Net investment income is declared as a dividend monthly and payment is made or
reinvestment is credited to shareholder accounts after month-end. Net realized
gains from securities transactions are distributed to shareholders not less
frequently than annually only to the extent they exceed available capital loss
carryovers. Distributions to shareholders of net investment income and net
realized gains from investment transactions are recorded on the ex-dividend
date. The amount and timing of such distributions are determined in accordance
with federal income tax regulations, which may differ from generally accepted
accounting principles. Accordingly, temporary over-distributions as a result of
these differences may result and will be classified as either distributions in
excess of net investment income or distributions in excess of net realized gains
from investment transactions, if applicable.

Federal income taxes

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

Insurance

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

                                      40

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


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

Flexible sales charge program

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

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

Derivative financial instruments

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

Use of estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of increases and decreases in net
assets from operations during the reporting period.

2. EXPENSE ALLOCATION

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

- ----------------------------------------------------------------------
</TABLE>

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

NOTES TO FINANCIAL STATEMENTS


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

8. COMPOSITION OF NET ASSETS

per share for Municipal Bond and $.01 par value per share for Insured Municipal
Bond. The composition of net assets as well as the number of authorized shares

</TABLE>

Certain long-term and intermediate-term investments owned by the Funds are
either covered by insurance issued by several private insurers or are backed by
an escrow or trust containing U.S. Government or U.S. Government agency
securities, both of which ensure the timely payment of principal and interest in
the event of default (30% for Municipal Bond and 100% for Insured Municipal
Bond). Such insurance or escrow, however, does not guarantee the market value of
the municipal securities or the value of the Funds' shares.

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

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

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

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

We have audited the accompanying statements of net assets of NUVEEN MUNICIPAL
BOND FUND (a Massachusetts Business Trust), and NUVEEN INSURED TAX-FREE BOND
FUND, INC. (comprising the Nuveen Insured Municipal Bond Fund) (a Minnesota
corporation), including the portfolios of investments, as of February 29, 1996,
and the related statements of operations for the year then ended, the statements
of changes in net assets for each of the two years in the period then ended and
the financial highlights for the periods indicated thereon. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
February 29, 1996, by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of each of the
respective funds constituting Nuveen Municipal Bond Fund and Nuveen Insured Tax-
Free Bond Fund, Inc. as of February 29, 1996, the results of their operations
for the year then ended, the changes in their net assets for each of the two
years in the period then ended and the financial highlights for the periods
indicated thereon in conformity with generally accepted accounting principles.

Dear
shareholder


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

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

  Over the past year, we have kept our sights focused on successfully meeting
your fund's objectives. As of February 29, 1996, the current annual SEC yield on
offering price for R shares for the mutual funds covered in this report ranged
from 4.21% to 4.99%. To match these yields, an investor in the 36% federal
income tax bracket would have had to earn between 6.58% to 7.80% on taxable
alternatives. The effect of state taxes further enhances the after-tax yield
advantage provided by municipal bonds.

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

  Reflecting the rebound in the bond markets, each of these funds reported gains
in portfolio value since February 28, 1995. The 12-month total returns on net
asset value for R Shares, reflecting portfolio gains plus reinvested dividend
income and capital gains distributions, if any, ranged from 9.70% to 10.80%,
which translate to 13.66% to 14.81% on a taxable-equivalent basis. This strong
performance rewarded investors who weathered the volatility of 1994, and reminds
us again of the importance of municipal bonds to a well-rounded, long-term
investment plan.

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

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

  The management transition has been well planned, and it will have no effect on
portfolio management or the way dividends are set. Our management team is

Answering your
questions


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

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

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

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

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

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

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

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

                                       6

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

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

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

                                       7

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

What is Nuveen's market outlook for 1996?

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

Nuveen Tax-Free Bond Fund, Inc.
Nuveen Insured Tax-Free Bond Fund, Inc.

statements and financial highlights are the responsibility of the Funds'
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
February 29, 1996, by correspondence with the custodian and brokers. As to
securities purchased but not received, we requested confirmation from brokers
and, when replies were not received, we carried out other alternative auditing
procedures. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

  In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the net assets of each of the
respective funds constituting the Nuveen California Tax-Free Fund, Inc., Nuveen

All of the bonds in the portfolio, exluding temporary investments in short-term
municipal securities, are either covered by Original Issue Insurance,
Secondary Market Insurance or Portfolio Insurance, or are backed by an escrow or
trust containing sufficient U.S. Government or U.S. Government
agency securities, any of which ensure the timely payment of principal and
interest.
* Optional Call Provisions (not covered by the report of independent public
accountants): Dates (month and year) and prices of the earliest optional
call or redemption. There may be other call provisions at varying prices at
later dates.
** Ratings (not covered by the report of independent public accountants): Using
the higher of Standard & Poor's or Moody's rating.
+ The security has a maturity of more than one year, but has variable rate and
demand features which qualify it as a short-term security. The rate disclosed
is that currently in effect. This rate changes periodically based on market
conditions or a specified market index.

All of the bonds in the portfolio, excluding temporary investments in short-term
municipal securities, are either covered by Original Issue Insurance, Secondary
Market Insurance or Portfolio Insurance, or are backed by an escrow or trust
containing sufficient U.S. Government or U.S. Government agency securities, any
of which ensure the timely payment of principal and interest.

* Optional call provisions (not covered by the report of independent public
accountants): Dates (month and year) and prices of the earliest optional call or
redemption. There may be other call provisions at varying prices at later dates

** Ratings (not covered by the report of independent public accountants): Using
the higher of Standard & Poor's or Moody's rating.

+ The security has a maturity of more than one year, but has variable rate and
demand features which qualify it as a short-term security. The rate disclosed is
that currently in effect. This rate changes periodically based on market
conditions or a specified market index.

NOTES TO FINANCIAL STATEMENTS


1. GENERAL INFORMATION AND SIGNIFICANT
ACCOUNTING POLICIES

At February 29, 1996, the state Funds (the "Funds") covered in this report are
Nuveen California Tax-Free Fund, Inc. (comprising the Nuveen California and
California Insured Tax-Free Value Funds), Nuveen Tax-Free Bond Fund, Inc.
(comprising the Nuveen Massachusetts, New York and Ohio Tax-Free Value Funds)
and Nuveen Insured Tax-Free Bond Fund, Inc. (comprising the Nuveen Massachusetts
and New York Insured Tax-Free Value Funds).

Additional state Funds covering other states may be established in the future.
Each Fund invests primarily in a diversified portfolio of municipal obligations
issued by state and local government authorities in a single state.

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

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

Securities valuation

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

Securities transactions

Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined using the specific identification
method. Securities purchased on a when-issued or delayed delivery basis may be
settled a month or more after the transaction date. Any securities so purchased
are subject to market fluctuations during this period. The Funds have instructed
the custodian to segregate assets in a separate account with a current value at
least equal to the amount of their purchase commitments. At February 29, 1996,
such purchase commitments in California Insured amount to $5,215,642. There were
no such purchase commitments in any of the other Funds.

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


Interest income

Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt securities
when required for federal income tax purposes.

Dividends and distribution to shareholders

Net investment income is declared as a dividend monthly and payment is made or
reinvestment is credited to shareholder accounts after month-end. Net realized
gains from investment transactions are distributed to shareholders not less
frequently than annually only to extent they exceed available capital loss
carryovers.

Distributions to shareholders of net investment income and net realized gains
from investment transactions are recorded on the ex-dividend date. The amount
and timing of such distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may result and will be classified as either distributions in excess
of net investment income or distributions in excess of net realized gains from
investment transactions, if applicable.

Income tax

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

Insurance

The California Insured, Massachusetts Insured and New York Insured Tax-Free
Value Funds invest in municipal securities which are either covered by insurance
or backed by an escrow or trust account containing sufficient U.S. Government or
U.S. Government agency securities, both of which ensure the timely payment of
principal and interest. Each insured municipal security is covered by Original
Issue Insurance, Secondary Market Insurance or Portfolio Insurance. Such
insurance does not guarantee the market value of the municipal securities or the
value of the Funds' shares. Original Issue Insurance and secondary Market
Insurance remain in effect as long as the municipal securities covered thereby
remain outstanding and the insurer remains in business, regardless of whether
the Funds ultimately dispose of such municipal securities. Consequently, the
market value of the municipal securities covered by Original Issue

                                      67

NOTES TO FINANCIAL STATEMENTS


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

Flexible sales charge program

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

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

Derivative financial instruments

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

Use of estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of increases and decreases in net
assets from operations during the reporting period.

2. EXPENSE ALLOCATION
Expenses of the Funds that are not directly attributable to any class of shares
are prorated among the classes based on the relative net assets of each class.
Expenses directly attributable to a class of shares are recorded to the specific
class. Effective August 1, 1995, the Funds adopted a multiple class plan
pursuant to Rule 18f-3 under the investment Company Act of 1940 and now
designate class specific expenses to include Rule 12b-1 distribution and service
fees, and other expenses incurred for services received by a class that differ
in either amount or kind. A breakdown of the class specific expenses is as
follows:

7. MANAGEMENT FEE AND OTHER TRANSACTIONS
WITH AFFILIATES

Under the Funds' investment management agreements with Nuveen Advisory Corp.
(the "Adviser"), a wholly owned subsidiary of The John Nuveen Company, each Fund
pays to the Adviser an annual management fee, payable monthly, at the rates set
forth below which are based upon the average daily net asset value of each Fund:

<TABLE> 
<CAPTION> 
- ------------------------------------------------------------
 Average daily net asset value        Management fee
- ------------------------------------------------------------
<S>                                  <C>    
For the first $125,000,000              .55 of 1%
For the next $125,000,000             .5375 of 1
For the next $250,000,000              .525 of 1
For the next $500,000,000             .5125 of 1
For the next $1,000,000,000              .5 of 1
For net assets over $2,000,000,000     .475 of 1
- ------------------------------------------------------------

</TABLE>

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

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

Certain long-term and intermediate-term investments owned by the Funds are
either covered by insurance issued by several private insurers or are backed by
an escrow or trust containing U.S. Government or U.S. Government agency
securities, both of which ensure the timely payment of principal and interest in
the event of default (39% for California, 100% for California Insured, 43% for
Massachusetts, 100% for Massachusetts Insured, 22% for New York, 100% for New
York Insured and 59% for Ohio). Such insurance, however, does not guarantee the
market value of the municipal securities or the value of the Fund's shares.

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

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

those persons who, at the request of the Corporation serve or have served an-
other corporation, partnership, joint venture, trust or other enterprise in one
or more such capacities. The indemnification provided for herein shall not be
deemed exclusive of any other rights to which those seeking indemnification may
otherwise be entitled.
 
Expenses (including attorneys' fees) incurred in defending a civil or criminal
action, suit or proceeding (including costs connected with the preparation of a
settlement) may be paid by the Corporation in advance of the final disposition
of such action, suit or proceeding, if authorized by the Board of Directors in
the specific case, upon receipt of an undertaking by or on behalf of the direc-
tor, officer, employee or agent to repay that amount of the advance which ex-
ceeds the amount which it is ultimately determined that he is entitled to re-
ceive from the Corporation by reason of indemnification as authorized herein;
provided, however, that prior to making any such advance at least one of the
following conditions shall have been met: (1) the indemnitee shall provide a
security for his undertaking; (2) the Corporation shall be insured against
losses arising by reason of any lawful advances, or (3) a majority of a quorum
of the disinterested, non-party directors of the Corporation, or an independent
legal counsel in a written opinion, shall determine, based on a review of read-
ily available facts, that there is reason to believe that the indemnitee ulti-
mately will be found entitled to indemnification.
 
Nothing in these Articles of Incorporation or in the By-Laws shall be deemed to
protect or provide indemnification to any director or officer of the Corpora-
tion against any liability to the Corporation or to its security holders to
which he would otherwise be subject by reason of willful misfeasance, bad
faith, gross negligence or reckless disregard of the duties involved in the
conduct of his office ("disabling conduct"), and the Corporation shall not in-
demnify any of its officers or directors against any liability to the Corpora-
tion or to its security holders unless a determination shall have been made in
the manner provided hereafter that such liability has not arisen from such of-
ficer's or director's disabling conduct. A determination that an officer or di-
rector is entitled to indemnification shall have been properly made if it is
based upon (1) a final decision on the merits by a court or other body before
whom the proceeding was brought that the indemnitee was not liable by reason of
disabling conduct or, (2) in the absence of such a decision, a reasonable de-
termination, based upon a review of the facts,
 
C-4
<PAGE>
 
that the indemnitee was not liable by reason of disabling conduct, by (a) the
vote of a majority of a quorum of directors who are neither "interested per-
sons" of the Corporation as defined in the Investment Company Act of 1940 nor
parties to the proceeding, or (b) an independent legal counsel in a written
opinion.
 
                               -----------------
   
The directors and officers of the Registrant are covered by an Investment Trust
Errors and Omission policy in the aggregate amount of $60,000,000 (with a maxi-
mum deductible of $500,000) against liability and expenses of claims of wrong-
ful acts arising out of their position with the Registrant, except for matters
which involve willful acts, bad faith, gross negligence and willful disregard
of duty (i.e., where the insured did not act in good faith for a purpose he or
she reasonably believed to be in the best interest of Registrant or where he or
she had reasonable cause to believe this conduct was unlawful).     
 
Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to the officers, directors or controlling persons of the
Registrant pursuant to the Articles of Incorporation of the Registrant or oth-
erwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as ex-
pressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by an officer or director or control-
ling person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such officer, director or controlling persons in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling prece-
dent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

tion, Chase succeeded by operation of law, all rights and responsibilities of
UST under all Transfer Agency, Custodian and Fund Accounting agreements be-
tween US Trust and John Nuveen & Co.'s managed investment companies.

     RE:  Registration Statement on Form N-1A
          Under the Securities Act of 1933
          (File No. 33-8372)
          --------------------------------------  

Dear Ladies and Gentlemen:

     We have acted as counsel to Nuveen Insured Tax-Free Bond Fund, Inc., a
Minnesota corporation (the "Fund"), in connection with the above-referenced
Registration Statement on Form N-1A (as amended the "Registration Statement")
which relates to the Fund's Nuveen Insured Municipal Bond Fund, Series A Shares;
Nuveen Insured Municipal Bond Fund, Series C Shares; Nuveen Insured Municipal
Bond Fund, Series R Shares; Nuveen Massachusetts Insured Tax-Free Value Fund,
Series A Shares; Nuveen Massachusetts Insured Tax-Free Value Fund, Series C
Shares; Nuveen Massachusetts Insured Tax-Free Value Fund, Series R Shares;
Nuveen New York Insured Tax-Free Value Fund, Series A Shares; Nuveen New York
Insured Tax-Free Value Fund, Series C Shares; and Nuveen New York Insured Tax-
Free Value Fund, Series R Shares, par value $.01 (collectively, the "Shares").
This opinion is being delivered to you in connection with the Fund's filing of
Post-Effective Amendment No. 19 to the Registration Statement (the "Amendment")
with the Securities and Exchange Commission pursuant to Rule 485(a)(1) of the
Securities Act of 1933 (the "1933 Act"). With your permission, all assumptions
and statements of reliance herein have been made without any independent
investigation or verification on our part except to the extent otherwise
expressly stated, and we express no opinion with respect to the subject matter
or accuracy of such assumptions or items relied upon.

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

     (a)  a certificate of the Secretary of State of the State of Minnesota as
          to the existence and good standing of the Fund;

     (b)  copies, certified by the Secretary of State of the State of Minnesota,
          of the Fund's Articles of Incorporation and of all amendments and all
          supplements thereto (the "Articles of Incorporation");

     (c)  a certificate executed by Karen L. Healy, an Assistant Secretary of
          the Fund, certifying as to the Fund's Articles of Incorporation and
          By-Laws, as amended (the "By-Laws"), and certain resolutions adopted
          by the Board of Directors of the Fund authorizing the issuance of the
          Shares; and

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

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

     Based upon, and subject to, the limitations set forth herein, we are of the
opinion that the Shares, when issued and sold in accordance with the Fund's 
Articles of Incorporation and for the consideration described in the 
Registration Statement, will be legally issued, fully paid and nonassessable.

     The opinion expressed herein is limited to the laws of the State of 
Minnesota.

     We hereby consent to the filing of this opinion as an exhibit to the 
Registration Statement. In giving this consent, we do not admit that we are in 
the category of persons whose consent is required under Section 7 of the 1933 
Act.


                                           Very truly yours,

                SCHEDULE OF COMPUTATION OF PERFORMANCE FIGURES*
 
                                    I. YIELD
 
A. Yield Formula
 
   Yield is computed according to the following formula:
 
                            6
             [ ( A - B     )      ]
   YIELD = 2 [ ( ----- + 1 ) - 1  ]
             [ (  CD       )      ]
 
Where: A = dividends and interest(degree symbol) earned during the period.
 
       B = expenses accrued for the period (net of reimbursements).
 
       C = the average daily number of shares outstanding during the period
           that were entitled to receive dividends.
 
       D = the maximum offering price per share on the last day of the period.
- --------
  *The maximum sales charge in effect during the periods shown was 4.50%.
 
  (degree symbol)Interest earned on tax-exempt obligations is determined as 
                 follows:
 
A. In the case of a tax-exempt obligation (1) with a current market premium or
   (2) issued at a discount where the current market discount is less than the
   then-remaining portion of the original issue discount, it is necessary to
   first compute the yield to maturity (YTM). The YTM is then divided by 360
   and the quotient is multiplied by the market value of the obligation (plus
   accrued interest).
 
B. In the case of a tax-exempt obligation issued at a discount where the cur-
   rent market discount is in excess of the then-remaining portion of the orig-
   inal issue discount, the adjusted original issue discount basis of the obli-
   gation (plus accrued interest) is used in lieu of the market value of the
   obligation (plus accrued interest) in computing the yield to maturity (YTM).
   The YTM is then divided by 360 and the quotient is multiplied by the ad-
   justed original issue basis of the obligation (plus accrued interest).
 
C. In the case of a tax-exempt obligation issued without original issue dis-
   count and having a current market discount, the coupon rate of interest is
   used in lieu of the yield to maturity. The coupon rate is then divided by
   360 and the quotient is multiplied by the par value of the obligation.
 
                                                                               1

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

                           V. CUMULATIVE TOTAL RETURN
 
A. Cumulative Total Return Formula
 
 Cumulative Total Return is computed according to the following formula:
 
 
                         ERV - P
                  T  =   -------
                            P

Where:  T = cumulative total return.
 
        P = a hypothetical initial payment of $1,000.
 
      ERV = ending redeemable value of a hypothetical $1,000 payment made at the
            inception of the Fund or at the first day of a specified 1-year, 5-
            year or 10-year period.

                      VI. TAXABLE EQUIVALENT TOTAL RETURN
 
A. Taxable Equivalent Total Return Formula
 
  Each Fund's taxable equivalent total return for a specific period is calcu-
lated by first taking a hypothetical initial investment in the Fund's shares on
the first day of the period, computing the Fund's total return for each calen-
dar year in the period according to the above formula, and increasing the total
return for each such calendar year by the amount of additional income that a
taxable fund would need to have generated to equal the income of the Fund on an
after-tax basis, at a specified tax rate (usually the highest marginal federal
or combined federal and state tax rate), calculated pursuant to the formula
presented above under "taxable equivalent yield." The resulting amount for the
calendar year is then divided by the initial investment amount to arrive at a
"taxable equivalent total return factor" for the calendar year. The taxable
equivalent total return factors for all the calendar years in the period are
then multiplied together and the result is then annualized by taking its Nth
root (N representing the number of years in the period) and subtracting 1,
which provides a taxable equivalent total return expressed as a percentage.
 
B. Taxable Equivalent Total Return Calculations
   
  The taxable equivalent total return calculations for the Class A Shares of
the National Fund for the one-year period ended February 29, 1996, and the pe-
riod from inception through February 29, 1996, are set forth on the following
pages. One set of calculations presents the Fund's taxable equivalent total re-
turn with the maximum 4.50% sales charge and the other set of calculations pre-
sents the taxable equivalent total return at the Fund's net asset value. Each
set of calculations assumes a 39.6% federal income tax rate based on 1996
rates.

                              Multiple Class Plan
                        Adopted Pursuant to Rule 18f-3


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

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

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

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

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

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

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

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

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

          a) Class A Shares:

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

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

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

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

          b) Class C Shares:

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

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

                      shareholders;

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

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

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

          c) Class R Shares:

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

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

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

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

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

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

                                       3
<PAGE>
 
class of shares. Class level expenses include expenses for services that are
unique to a class of shares in either form or amount. "Class level expenses"
shall include, but not be limited to, 12b-1 Service Fees, 12b-1 Distribution
Fees, expenses associated with the addition of share classes to a fund (to the
extent that the expenses were not fully accrued prior to the issuance of the new
classes of shares), expenses of administrative personnel and services required
to support the shareholders of a specific class, litigation or other legal
expenses relating to a specific class of shares, directors' fees or expenses
incurred as a result of issues relating to a specific class of shares, and
accounting expenses relating to a specific class of shares.

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

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

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

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

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

                                       4

     6.   Subsequent Funds. The parties hereto intend that any open-end
investment company established subsequent to the date set forth below for which
Nuveen Advisory Corp. acts as investment adviser (each a "Future Fund"), will be
covered by the terms and conditions of this Plan, provided that the Board of
such Future Fund as a whole, and the Non-Interested Members of such Future Fund,
after having been furnished and having evaluated information reasonably
necessary to evaluate the Plan, have determined in the exercise of their
reasonable business judgment that the Plan is in the best interests of each
class of each Series of such Future Fund individually, and each Series of such
Future Fund and such Future Fund as a whole.

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

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