Schwertfeger Chairman of the Board Sidebar text: WE THINK THAT MUNICIPAL BOND INVESTMENTS LIKE YOUR NUVEEN FUND CAN BE IMPORTANT BUILDING BLOCKS IN A WELL-BALANCED PORTFOLIO. Dear SHAREHOLDER I am very pleased to report that for the period ended April 30, 2004, your Nuveen Fund continued to provide you with attractive monthly tax-free income. While tax-free income is always welcome, we know that many shareholders are beginning to wonder whether interest rates will rise significantly, and whether that possibility should cause them to adjust that portion of their investment portfolios allocated to tax-free municipal bonds. We believe this is a question you should consider carefully with the help of a trusted financial advisor. In many cases, it may be more appropriate to focus on long-term goals and objectives rather than shorter-term market movements, and this is where a professional advisor may be able to help keep you focused on the larger objectives of your investment program. As you read through this report, please review the inside front cover and consider receiving future Fund reports and other Fund information by e-mail and the Internet. Not only will you be able to receive the information faster, but this also may help lower your Fund's expenses. Sign up is quick and easy. Since 1898, Nuveen Investments has offered financial products and solutions that incorporate careful research, diversification and the application of conservative risk-management principles. We are grateful that you have chosen us as a partner as you pursue your financial goals. We look forward to continuing to earn your trust in the months and years ahead. Sincerely, /s/ Timothy R. Schwertfeger Timothy R. Schwertfeger Chairman of the Board June 15, 2004 1 Nuveen National Insured Municipal Closed-End Exchange-Traded Funds (NQI, NIO, NIF, NPX, NVG, NEA) Portfolio Manager's COMMENTS Portfolio manager Tom O'Shaughnessy reviews the market environment, key investment strategies, and the six-month performance of the Funds. With 21 years of investment experience at Nuveen, Tom assumed portfolio management responsibility for NEA at its inception in 2002, adding NQI, NIO, NIF, NPX, and NVG in 2003. After the end of this six-month reporting period, management responsibility for these Funds switched to Dan Solender. Dan has eleven years of investment experience, including seven at Nuveen. The investment objectives of the Funds have not changed.) WHAT FACTORS AFFECTED THE U.S. ECONOMY AND MUNICIPAL MARKET DURING THE SIX-MONTH REPORTING PERIOD ENDED APRIL 30, 2004? During this reporting period, the greatest influences on the national economy and the municipal market continued to be historically low interest rates, growing evidence of economic improvement, and a generally modest rate of inflation. Since its last credit easing in June 2003, the Federal Reserve has maintained the fed funds rate at 1.0%, the lowest level since 1958. This accommodative monetary policy helped to spur GDP (gross domestic product) growth of 4.4% annualized in the first quarter of 2004, following a 3.1% rise in 2003. Over the six-month reporting period, the year-over-year rate of inflation, as measured by the core Consumer Price Index, averaged 1.3%. This generally favorable environment helped many municipal bonds perform well during most of the six-month period ended April 30, 2004. However, in early April, a sharply improved jobs report, along with subsequent indications of growing momentum in the U.S. economy, served as catalysts for increased expectations of a Fed rate hike. This all contributed to heightened volatility in the fixed-income markets. During April, the yield on the Bond Buyer 20 index, a widely followed measure of general obligation bonds, rose more than 50 basis points. This rise in the index yield, and the corresponding decline in bond prices, effectively offset the yield declines and price gains of the previous five months. As of April 30, 2004, the Bond Buyer 20 index was at approximately the same level as it was at the beginning of the six-month reporting period. In general, municipal supply remained strong over the past six months, although the pace of issuance slowed. The first four months of 2004 saw $110 billion in new municipal supply, down 9% from January-April 2003. Over the entire six-month reporting period ended April 2004, the supply of new bonds decreased 13% compared with the preceding six months. IN THIS ENVIRONMENT, WHAT KEY STRATEGIES WERE USED TO MANAGE THE FUNDS DURING THE SIX MONTHS ENDED APRIL 30, 2004? With the market continuing to anticipate an increase in interest rates, our major focus during this reporting period remained on careful management of the Funds' durations1 as a way to mitigate some of the interest rate risk inherent in each Fund's portfolio. Interest rate risk is the risk that the value of a Fund's portfolio will decline if market interest rates rise (since bond prices move in the opposite direction of interest rates). The longer the duration of a Fund's portfolio, the greater the 1 Duration is a measure of a Fund's net asset value (NAV) volatility in reaction to interest rate movements. Fund duration, also known as leverage-adjusted duration, takes into account the leveraging process for a Fund and therefore is generally longer than the duration of the actual portfolio of individual bonds that make up the Fund. References to duration in this commentary are intended to indicate Fund duration unless otherwise noted. 2 Fund's interest rate risk. Our use of such a duration management strategy is designed to help position the Funds to potentially produce more consistent returns over time as interest rates inevitably rise and fall. The one exception to this strategy was NEA, the newest of these six Funds. With NEA, we made a deliberate decision to keep the duration longer than the other Funds in order to enhance this Fund's initial income stream. As mentioned earlier, the supply of new municipal bonds softened nationwide during the six-month reporting period. This tighter supply had a modest impact on our ability to enhance the diversification of the two newer Funds, NVG and NEA, since it occasionally took longer to find securities that we believed had the potential to add value and that carried the types of structures and features we preferred. In addition, with yields remaining low over most of this period, the market did not offer a great number of opportunities to improve the Funds' income streams. In general, turnover in these Funds was comparatively low for the six months ended April 30, 2004. In keeping with our duration management strategy and the steepness of the municipal bond yield curve over this reporting period, the bonds we did purchase tended to be in the long-intermediate part of the yield curve (i.e., bonds that mature in 16 to 20 years). In many cases, bonds in this part of the curve offered yields similar to those of longer-term bonds with less inherent interest rate risk and better total return potential. Overall, we looked for bonds that would help us keep the Funds' portfolios diversified in terms of industry sector, maturity and geographic region. Another ongoing strategy focused on the gradual reduction of the Funds' exposure to bonds subject to the alternative minimum tax (AMT). In accomplishing this, we looked to use tax loss carryforwards whenever possible to offset gains realized when we sold bonds that had appreciated in value. HOW DID THE FUNDS PERFORM? Individual results for the Funds, as well as for relevant benchmarks, are presented in the accompanying table. TOTAL RETURNS ON NET ASSET VALUE For periods ended 4/30/04 (6-month returns cumulative, all others annualized) 6-MONTH 1-YEAR 5-YEAR 10-YEAR --------------------------------------------------------------------- NQI 1.01% 1.77% 6.09% 6.88% --------------------------------------------------------------------- NIO 0.66% 2.16% 6.11% 7.06% --------------------------------------------------------------------- NIF 1.06% 1.84% 5.63% 6.74% --------------------------------------------------------------------- NPX 0.83% 1.79% 5.95% 7.41% --------------------------------------------------------------------- NVG 1.72% 2.42% NA NA --------------------------------------------------------------------- NEA 1.92% 2.88% NA NA --------------------------------------------------------------------- Lehman Brothers Insured Municipal Bond Index2 1.06% 2.41% 5.64% 6.67% --------------------------------------------------------------------- Lipper Insured (Leveraged) Municipal Debt Funds average3 1.01% 2.25% 5.49% 6.87% --------------------------------------------------------------------- Past performance is not predictive of future results. For additional information, see the individual Performance Overview for your Fund in this report. 3 For the six months ended April 30, 2004, the cumulative returns of NVG and NEA outperformed the returns of both the Lehman Brothers Insured Municipal Bond Index and the Funds' Lipper peer group average. The returns of NQI and NIF were in line with these measures, while the returns of NIO and NPX trailed both the Lehman and Lipper returns. In general, insured and higher-rated bonds did not perform as well as BBB rated bonds during this six-month period, and this is reflected in the returns of all these Funds, as well as the Lehman Index and Lipper peer group. Both NVG and NEA performed the best during this period, in large part because they are allowed to invest in uninsured, lower-rated investment-grade securities. NEA also benefited from its holdings of uninsured healthcare bonds. Healthcare, which ranked second in terms of returns among the Lehman municipal revenue sectors during this period, continued to perform well due to improvements in cost containment and reimbursement practices. Looking at the fully insured Funds, NIO and NPX underperformed NQI and NIF for several reasons. First, NIO and NPX had relatively more housing bond calls than the other two Funds, and thus had more funds to invest at current low rates. These Funds also had higher levels of pre-refunded bonds than NQI or NIF and pre-refunded bonds tended to underperform relative to other bonds over this period. Another factor that constrained the performances of NIO and NPX during this period included their relatively large exposure to AMT bonds. In recent months, these bonds did not perform as well as their non-AMT counterparts. HOW ABOUT THE FUNDS' DIVIDENDS AND SHARE PRICES? With short-term interest rates remaining at historically low levels during this reporting period, the leveraged structures of these Funds continued to support their dividend-paying capabilities. The extent of this benefit is tied in part to the short-term rates the Funds pay their MuniPreferred(R) shareholders. During periods of low short-term rates, the Funds generally pay relatively lower dividends to their MuniPreferred shareholders, which can leave more earnings to support common share dividends. During this reporting period, continued low short-term rates enabled us to maintain the dividend levels of all six insured Funds. All of these Funds seek to pay stable dividends at rates that reflect each Fund's past results and projected future performance. During certain periods, each Fund may pay dividends at a rate that may be more or less than the amount of net investment income actually earned by the Fund during the period. If a Fund has cumulatively earned more than it has paid in dividends, it holds the excess in reserve as undistributed net investment income (UNII) as part of the Fund's net asset value (NAV). Conversely, if a Fund has 2 The Lehman Brothers Insured Municipal Bond Index is an unleveraged, unmanaged national index comprising a broad range of insured municipal bonds. Results for the Lehman index do not reflect any expenses. 3 The Lipper Insured (Leveraged) Municipal Debt Funds category average is calculated using the returns of all closed-end exchange-traded funds in this category for each period as follows: 6 months - 27 funds; 1 year - 26 funds; 5 years - 20 funds and 10 years - 18 funds. Fund and Lipper returns assume reinvestment of dividends. 4 cumulatively paid dividends in excess of its earnings, the excess constitutes negative UNII that is likewise reflected in the Fund's NAV. Each Fund will, over time, pay all of its net investment income as dividends to shareholders. As of April 30, 2004, all of the Funds in this report had positive UNII balances except NEA, which had a negative UNII balance mainly because it is a newer Fund that has not been around long enough to accumulate its income. As of April 30, 2004, NIO was trading at a -4.04% discount to its NAV, compared with an average premium of 34.7% for the six-month period. NIO was trading at a -8.45% discount, compared with an average discount of -1.09%. NIF was at a discount of -7.36%, compared with an average premium for the period of 0.12%. NPX was at a -8.61% discount, compared to an average premium of 0.29%. NVG was at a discount at -9.44%, compared to an average discount of -4.17%. NEA was trading at a discount of -5.92%, compared with an average premium of 0.45% for the reporting period. HOW WERE THE FUNDS POSITIONED IN TERMS OF CREDIT QUALITY AND BOND CALLS AS OF APRIL 30, 2004? Given the current geopolitical and economic climate, we continued to believe that maintaining strong overall credit quality was an important requirement. NQI, NIO, NIF and NPX continued to be 100% invested in insured and/or U.S. guaranteed securities. As noted, NVG and NEA are allowed to invest up to 20% of their assets in uninsured investment-grade quality securities. As of April 30, 2004, NVG had 91% of its portfolio in insured bonds, while NEA had 88%. As of April 30, 2004, potential call exposure for these Funds during 2004-2005 ranged from zero in NVG and 1% in NEA to 7% in NIF, 11% in NPX, 14% in NIO, and 20% in NQI. The number of actual bond calls in all of these Funds will depend largely on market rates and the needs of the securities' issuers. We continue to manage these insured Funds as long-term investments focused on providing dependable tax-free income and preserving net asset value through the prudent management of credit and interest rate risk. 5 Nuveen Insured Quality Municipal Fund, Inc.

FINANCIAL STATEMENTS (Unaudited) 1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES The National Funds (the "Funds") covered in this report and their corresponding Common share stock exchange symbols are Nuveen Insured Quality Municipal Fund, Inc. (NQI), Nuveen Insured Municipal Opportunity Fund, Inc. (NIO), Nuveen Premier Insured Municipal Income Fund, Inc. (NIF), Nuveen Insured Premium Income Municipal Fund 2 (NPX), Nuveen Insured Dividend Advantage Municipal Fund (NVG) and Nuveen Insured Tax-Free Advantage Municipal Fund (NEA). Common shares of Insured Quality (NQI), Insured Opportunity (NIO), Premier Insured Income (NIF) and Insured Premium Income 2 (NPX) are traded on the New York Stock Exchange while Common shares of Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA) are traded on the American Stock Exchange. The Funds are registered under the Investment Company Act of 1940, as amended, as closed-end, diversified management investment companies. Prior to the commencement of operations of Insured Tax-Free Advantage (NEA), the Fund had no operations other than those related to organizational matters, the initial capital contribution of $100,275 by Nuveen Advisory Corp. (the "Adviser"), a wholly owned subsidiary of Nuveen Investments, Inc. and the recording of the organization expenses ($11,500) and their reimbursement by Nuveen Investments, LLC, also a wholly owned subsidiary of Nuveen Investments, Inc. Each Fund seeks to provide current income exempt from regular federal income tax, and in the case of Insured Tax-Free Advantage (NEA) the alternative minimum tax applicable to individuals, by investing primarily in a diversified portfolio of municipal obligations issued by state and local government authorities. The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements in accordance with accounting principles generally accepted in the United States. Securities Valuation The prices of municipal bonds in each Fund's investment portfolio are provided by a pricing service approved by the Fund's Board of Directors/Trustees. When price quotes are not readily available (which is usually the case for municipal securities), the pricing service establishes fair market value based on yields or prices of municipal bonds of comparable quality, type of issue, coupon, maturity and rating, indications of value from securities dealers, evaluations of anticipated cash flows or collateral and general market conditions. If it is determined that market prices for a security are unavailable or inappropriate, the Board of Directors/Trustees of the Funds, or its designee, may establish a fair value for the security. Temporary investments in securities that have variable rate and demand features qualifying them as short-term securities are valued at amortized cost, which approximates market value. Securities Transactions Securities transactions are recorded on a trade date basis. Realized gains and losses from such transactions are determined on the specific identification method. Securities purchased or sold on a when-issued or delayed delivery basis may have extended settlement periods. The securities so purchased are subject to market fluctuation during this period. The Funds have instructed the custodian to segregate assets with a current value at least equal to the amount of the when-issued and delayed delivery purchase commitments. At April 30, 2004, Insured Opportunity (NIO), Premier Insured Income (NIF) and Insured Tax-Free Advantage (NEA) had outstanding when-issued purchase commitments of $1,108,380, $1,419,337, and $8,423,947, respectively. There were no such outstanding purchase commitments in any of the other Funds. Investment Income Interest income, which includes the amortization of premiums and accretion of discounts for financial reporting purposes, is recorded on an accrual basis. Federal Income Taxes Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its net investment income to its shareholders. Therefore, no federal income tax provision is required. Furthermore, each Fund intends to satisfy conditions which will enable interest from municipal securities, which is exempt from regular federal income tax, and in the case of Insured Tax-Free Advantage (NEA) the alternative minimum tax applicable to individuals, to retain such tax-exempt status when distributed to shareholders of the Funds. 54 Dividends and Distributions to Common Shareholders Dividends from tax-exempt net investment income are declared monthly. Net realized capital gains and/or market discount from investment transactions, if any, are distributed to shareholders not less frequently than annually. Furthermore, capital gains are distributed only to the extent they exceed available capital loss carryforwards. Distributions to Common shareholders of tax-exempt net investment income, net realized capital gains and/or market discount, if any, are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States. Preferred Shares The Funds have issued and outstanding $25,000 stated value Preferred shares. Each Fund's Preferred shares are issued in more than one Series. The dividend rate on each Series may change every seven days, as set pursuant to a dutch auction process by the auction agent, and is payable at or near the end of each rate period. The number of Preferred shares outstanding, by Series and in total, for each Fund is as follows: PREMIER INSURED INSURED INSURED INSURED INSURED INSURED PREMIUM DIVIDEND TAX-FREE QUALITY OPPORTUNITY INCOME INCOME 2 ADVANTAGE ADVANTAGE (NQI) (NIO) (NIF) (NPX) (NVG) (NEA) --------------------------------------------------------------------------------------------------------- Number of shares: Series M 2,600 4,000 -- 2,080 3,160 -- Series T 2,600 4,000 -- 2,200 3,080 2,880 Series W 2,600 4,000 840 2,080 -- 2,880 Series W2 -- 3,200 -- -- -- -- Series TH 2,320 4,000 2,800 2,200 3,080 -- Series TH2 -- 4,000 -- -- -- -- Series F 2,600 4,000 2,800 2,196 -- -- --------------------------------------------------------------------------------------------------------- Total 12,720 27,200 6,440 10,756 9,320 5,760 ========================================================================================================= Effective January 17, 2003, Insured Tax-Free Advantage (NEA) issued 2,880 Series T and 2,880 Series W, $25,000 stated value Preferred shares. Insurance Insured Quality (NQI), Insured Opportunity (NIO), Premier Insured Income (NIF) and Insured Premium Income 2 (NPX) invest in municipal securities which are either covered by insurance or are 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. Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA) invest at least 80% of their net assets (including net assets applicable to Preferred shares) in municipal securities that are covered by insurance. Each Fund may also invest up to 20% of its net assets (including net assets applicable to Preferred shares) in municipal securities which are either (i) backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities, or (ii) municipal bonds that are rated, at the time of investment, within the four highest grades (Baa or BBB or better by Moody's, S&P or Fitch) or unrated but judged to be of comparable quality by the Adviser. 55 Notes to FINANCIAL STATEMENTS (Unaudited) (continued) 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' Common 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 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 Common share net asset value of the Funds 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. Derivative Financial Instruments The Funds may invest in certain derivative financial instruments including futures, 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 six months ended April 30, 2004. Custodian Fee Credit Each Fund has an arrangement with the custodian bank whereby certain custodian fees and expenses are reduced by credits earned on each Fund's cash on deposit with the bank. Such deposit arrangements are an alternative to overnight investments. Offering Costs Nuveen Investments, LLC has agreed to pay all Common share offering costs (other than the sales load) that exceed $.03 per Common share for Insured Tax-Free Advantage (NEA). Insured Tax-Free Advantage's (NEA) share of Common share offering costs ($440,201) was recorded as a reduction of the proceeds from the sale of Common shares. Costs incurred by Insured Tax-Free Advantage (NEA) in connection with the offering of Preferred shares ($3,084,842) were recorded as a reduction to paid-in surplus. Indemnifications Under the Funds' organizational documents, its Officers and Directors/Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that provide general indemnifications to other parties. The Funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 applicable to Common shares from operations during the reporting period. Actual results may differ from those estimates. 2.

INCOME TAX INFORMATION The following information is presented on an income tax basis.

MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES Under the Funds' (excluding Insured Dividend Advantage (NVG) and Insured Tax-Free Advantage (NEA)) investment management agreements with the Adviser, each Fund pays an annual management fee, payable monthly, at the rates set forth below, which are based upon the average daily net assets (including net assets attributable to Preferred shares) of each Fund as follows: AVERAGE DAILY NET ASSETS (INCLUDING NET ASSETS ATTRIBUTABLE TO PREFERRED SHARES) MANAGEMENT FEE -------------------------------------------------------------------------------- For the first $125 million .6500% For the next $125 million .6375 For the next $250 million .6250 For the next $500 million .6125 For the next $1 billion .6000 For the next $3 billion .5875 For net assets over $5 billion .5750 ================================================================================ Under Insured Dividend Advantage's (NVG) and Insured Tax-Free Advantage's (NEA) investment management agreements with the Adviser, each Fund pays an annual management fee, payable monthly, at the rates set forth below, which are based upon the average daily net assets (including net assets attributable to Preferred shares) of each Fund as follows: AVERAGE DAILY NET ASSETS (INCLUDING NET ASSETS ATTRIBUTABLE TO PREFERRED SHARES) MANAGEMENT FEE -------------------------------------------------------------------------------- For the first $125 million .6500% For the next $125 million .6375 For the next $250 million .6250 For the next $500 million .6125 For the next $1 billion .6000 For net assets over $2 billion .5750 ================================================================================ The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Funds pay no compensation directly to those of its Directors/Trustees who are affiliated with the Adviser or to their officers, all of whom receive remuneration for their services to the Funds from the Adviser or its affiliates. As approved by the Board of Directors/Trustees, a complex-wide fee schedule for all Funds managed by the Advisor and its affiliates will go into effect on August 1, 2004. This complex-wide fee schedule is expected to marginally decrease the rate at which management fees are to be paid by the Funds. Under no circumstances will the complex-wide fee schedule result in an increase in the rate at which management fees would be paid by the Funds if the complex-wide fee schedule were not implemented. For the first ten years of Insured Dividend Advantage's (NVG) operations, the Adviser has agreed to reimburse the Fund, as a percentage of average daily net assets (including net assets attributable to Preferred shares), for fees and expenses in the amounts and for the time periods set forth below: YEAR ENDING YEAR ENDING MARCH 31, MARCH 31, -------------------------------------------------------------------------------- 2002* .30% 2008 .25% 2003 .30 2009 .20 2004 .30 2010 .15 2005 .30 2011 .10 2006 .30 2012 .05 2007 .30 ================================================================================ * From the commencement of operations.

A PHONE CALL IS ALL IT TAKES TO SET UP YOUR REINVESTMENT ACCOUNT. NUVEEN CLOSED-END EXCHANGE-TRADED FUNDS DIVIDEND REINVESTMENT PLAN Your Nuveen Closed-End Exchange-Traded Fund allows you to conveniently reinvest dividends and/or capital gains distributions in additional fund shares. By choosing to reinvest, you'll be able to invest money regularly and automatically, and watch your investment grow through the power of tax-free compounding. Just like dividends or distributions in cash, there may be times when income or capital gains taxes may be payable on dividends or distributions that are reinvested. It is important to note that an automatic reinvestment plan does not ensure a profit, nor does it protect you against loss in a declining market. EASY AND CONVENIENT To make recordkeeping easy and convenient, each month you'll receive a statement showing your total dividends and distributions, the date of investment, the shares acquired and the price per share, and the total number of shares you own. HOW SHARES ARE PURCHASED The shares you acquire by reinvesting will either be purchased on the open market or newly issued by the Fund. If the shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the then-current market price. If the shares are trading at less than net asset value, shares for your account will be purchased on the open market. Dividends and distributions received to purchase shares in the open market will normally be invested shortly after the dividend payment date. No interest will be paid on dividends and distributions awaiting reinvestment. Because the market price of shares may increase before purchases are completed, the average purchase price per share may exceed the market price at the time of valuation, resulting in the acquisition of fewer shares than if the dividend or distribution had been paid in shares issued by the Fund. A pro rata portion of any applicable brokerage commissions on open market purchases will be paid by Plan participants. These commissions usually will be lower than those charged on individual transactions. FLEXIBILITY You may change your distribution option or withdraw from the Plan at any time, should your needs or situation change. Should you withdraw, you can receive a certificate for all whole shares credited to your reinvestment account and cash payment for fractional shares, or cash payment for all reinvestment account shares, less brokerage commissions and a $2.50 service fee. You can reinvest whether your shares are registered in your name, or in the name of a brokerage firm, bank, or other nominee. Ask your investment advisor if his or her firm will participate on your behalf. Participants whose shares are registered in the name of one firm may not be able to transfer the shares to another firm and continue to participate in the Plan. The Fund reserves the right to amend or terminate the Plan at any time. Although the Fund reserves the right to amend the Plan to include a service charge payable by the participants, there is no direct service charge to participants in the Plan at this time. For more information on the Nuveen Automatic Reinvestment Plan or to enroll in or withdraw from the Plan, speak with your financial advisor or call us at (800) 257-8787. 64 Fund INFORMATION BOARD OF DIRECTORS/TRUSTEES Robert P.

Box 43071 Providence, RI 02940-3071 (800) 257-8787 LEGAL COUNSEL Chapman and Cutler LLP Chicago, IL INDEPENDENT AUDITORS Ernst & Young LLP Chicago, IL PROXY VOTING POLICIES AND PROCEDURES A description of the policies and procedures that the Funds use to determine how to vote proxies relating to portfolio securities is available (i) without charge, upon request, by calling Nuveen Investments at (800) 257-8787; and (ii) on the Commission's website at http://www.sec.gov. POLICY CHANGE On February 25, 2004, the Board approved policies that would allow NVG and NEA at the discretion of the Adviser, to engage in certain types of derivative transactions for the purpose of hedging interest rate risk. There is no guarantee that the Adviser will cause a Fund to enter into such transactions. If a Fund were to engage in hedging, there is no guarantee that such hedging will be successful. GLOSSARY OF TERMS USED IN THIS REPORT AVERAGE ANNUAL TOTAL RETURN: This is a commonly used method to express an investment's performance over a particular, usually multi-year time period. It expresses the return (including change in NAV and reinvested dividends) that would have been necessary on an annual basis to equal the investment's actual performance over the time period being considered. AVERAGE EFFECTIVE MATURITY: The average of all the maturities of the bonds in a fund's portfolio, computed by weighting each maturity date (the date the security comes due) by the market value of the security. This figure does not account for the likelihood of prepayments or the exercise of call provisions. LEVERAGE-ADJUSTED DURATION: Duration is a measure of a bond or bond fund's sensitivity to changes in interest rates. Generally, the longer a bond or fund's duration, the more the price of the bond or fund will change as interest rates change. Leverage-adjusted duration takes into account the leveraging process for a Fund and therefore is generally longer than the duration of the actual portfolio of individual bonds that make up the Fund. MARKET YIELD (ALSO KNOWN AS DIVIDEND YIELD OR CURRENT YIELD): An investment's current annualized dividend divided by its current market price. NET ASSET VALUE (NAV): A fund's NAV is calculated by subtracting the liabilities of the fund from its total assets and then dividing the remainder by the number of shares outstanding. Fund NAVs are calculated at the end of each business day. TAXABLE-EQUIVALENT YIELD: The yield necessary from a fully taxable investment to equal, on an after-tax basis, the yield of a municipal bond investment. ---------- *Director/Trustee will be retiring on June 30, 2004. Each Fund intends to repurchase shares of its own common or preferred stock in the future at such times and in such amounts as is deemed advisable. No shares were purchased during the six-months ended April 30, 2004. Any future repurchases will be reported to shareholders in the next annual or semiannual report. 65 Serving Investors FOR GENERATIONS Since 1898, financial advisors and their clients have relied on Nuveen Investments to provide dependable investment solutions.
