Schwertfeger Chairman of the Board June 15, 2002 1 Nuveen National Insured Municipal Closed-End Exchange-Traded Funds (NQI, NIO, NIF, NPX, NVG) Portfolio Manager's COMMENTS Portfolio manager Steve Krupa examines economic and market conditions, key strategies, and the performance of the Nuveen National Insured Municipal Closed-End Exchange-Traded Funds. Steve, who has 22 years of experience as an investment professional at Nuveen, has managed NQI and NIO since their inceptions in 1990 and 1991, respectively. He added NIF and NPX in 1998 and NVG upon its inception in March 2002. WHAT FACTORS HAD THE GREATEST INFLUENCE ON THE U.S. ECONOMY AND THE MUNICIPAL MARKET DURING THIS REPORTING PERIOD? The two major forces at work during the twelve months ended April 30, 2002, were the general slowdown in economic growth and the Federal Reserve's aggressive easing of short-term interest rates. In addition, the events of September 11, 2001, and the uncertain geopolitical climate that followed also have impacted the economy and the markets. In the municipal markets, the generally sluggish economic environment of the past twelve months helped many securities perform well. In addition, the trend toward increased issuance remained strong. Looking at the first four months of 2002, new issue supply reached $87 billion, up about 10% over January-April 2001. On the demand side, municipal bonds continued to be highly sought after by individual investors looking for diversification, tax-free income and an alternative to a volatile stock market. Institutional investors, especially traditional purchasers such as property/casualty insurance companies and pension plans, also have been active buyers in the new issue market. HOW DID THESE NUVEEN FUNDS PERFORM OVER THE PAST TWELVE MONTHS? For the year ended April 30, 2002, these Nuveen Funds produced total annual returns on net asset value (NAV) as shown in the accompanying table. The annual returns for the Lehman Brothers Insured Municipal Bond Index1 and relevant Lipper Peer Group2 also are presented. TOTAL RETURN LEHMAN LIPPER MARKET YIELD ON NAV TOTAL RETURN1 AVERAGE2 ------------------------------------------------------------------------- 1 YEAR 1 YEAR 1 YEAR TAXABLE- ENDED ENDED ENDED 4/30/02 EQUIVALENT3 4/30/02 4/30/02 4/30/02 ------------------------------------------------------------------------- NQI 6.06% 8.66% 9.39% 7.37% 8.21% ------------------------------------------------------------------------- NIO 6.14% 8.77% 8.27% 7.37% 8.21% ------------------------------------------------------------------------- NIF 6.23% 8.90% 7.93% 7.37% 8.21% ------------------------------------------------------------------------- NPX 6.11% 8.73% 8.46% 7.37% 8.21% ------------------------------------------------------------------------- NVG N/A N/A N/A --- --- ------------------------------------------------------------------------- Past performance is not predictive of future results. For additional information, see the individual Performance Overview for your Fund in this report. Over the past twelve months, the Fed's policy to reduce short-term interest rates, combined with generally favorable market conditions, created a positive total return environment for municipal bonds. The Funds' participation in the market's gains is reflected, in part, in the total returns on NAV listed in the above table. In a market characterized by rising bond values, funds or indexes with longer durations4 would typically be expected to outperform funds or indexes with shorter durations. As of April 30, 2002, the durations of the four older Funds ranged from 9.63 to 12.33, compared with 8.60 for the unleveraged Lehman Brothers Insured Municipal Bond Index. NVG was still in its initial investing period as of April 30, 2002, and did not have a meaningful duration to report as of that date. HOW DID THE MARKET ENVIRONMENT AFFECT THE FUNDS' DIVIDENDS AND SHARE PRICES? With the Fed's policy of interest rate easing over the past year, the dividend-payment capabilities of the four older Funds benefited from the use of leverage, a strategy that can potentially enhance the dividends paid to common shareholders. The amount of this benefit is tied in part to the short-term rates the Funds pay their MuniPreferred(R) shareholders. For example, declining short-term 1 The Funds' performances are compared with that of the Lehman Brothers Insured Municipal Bond Index, an unleveraged index comprising a broad range of insured municipal bonds. Results for the Lehman index do not reflect any expenses. 2 The Funds' total returns are compared with the average annualized return of the 22 funds in the Lipper Insured Leveraged Municipal Debt Funds category. Fund and Lipper returns assume reinvestment of dividends. 3 The taxable-equivalent yield represents the yield that must be earned on a taxable investment in order to equal the yield of the Nuveen Fund on an after-tax basis. The taxable-equivalent yield is based on the Fund's market yield on the indicated date and a federal income tax rate of 30%. 4 Duration is a measure of a Fund's 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. Unless otherwise noted, references to duration in this commentary are intended to indicate Fund duration. 2 rates can enable the Funds to reduce the amount of income they pay preferred shareholders, which can leave more earnings to support common share dividends. During the year ended April 30, 2002, steady or falling short-term interest rates enabled a series of dividend increases for all four of the older Funds. The level of short-term rates, the number and timing of bond calls, and the interest rates at which we can reinvest the proceeds of any calls will all influence the dividends of these Funds over the next twelve months. After the close of the April 30, 2002, reporting period, NVG announced it would pay its first monthly dividend on June 3, 2002. Over the year ended April 30, 2002, as the stock market remained volatile and the bond market continued to perform well, many investors turned to tax-free fixed-income investments as a way to add balance to their portfolios and reduce their overall portfolio risk. As a result, the share prices of the four older Funds improved (see the charts on the individual Performance Overview pages). NVG has traded well since its IPO in late March 2002. As investors recognized the opportunity offered by these Funds, increased demand caused their discounts (share price below NAV) to narrow over the twelve months ended April 30, 2002. WHAT KEY STRATEGIES WERE USED TO MANAGE THE NUVEEN NATIONAL INSURED FUNDS DURING THE REPORTING PERIOD APRIL 30, 2002? During this period, we focused on enhancing the dividend-paying capabilities and improving the call protection of all of these Funds. Each of the four older Funds has experienced some bond calls recently, and the timing and number of future calls will depend largely on the level of interest rates over time. Currently, low rate levels have caused us to hold higher-yielding bonds as long as practical to help support the Funds' dividends while we look for attractive replacement opportunities. We believe the potential call exposure in each of the four older Funds is very manageable. As we've had call proceeds to invest, we've been looking at insured airport and general obligation bonds, among other sectors. In our opinion, insured bonds in these areas had sold off through the fall and winter to some very attractive levels, and we've been able to find a number of attractive opportunities. In addition to providing increased call protection, we believe these undervalued bonds will help maintain the Funds' income and dividend-paying capabilities over time. All of the Funds remain 100% invested in bonds that are insured or backed by U.S. guaranteed securities. NVG has the ability to invest up to 20% of its assets in investment-grade quality securities. We believe this strong credit quality in today's uncertain economic environment is one of the reasons behind the Funds' strong performance over this reporting period. WHAT IS YOUR OUTLOOK FOR THE MUNICIPAL MARKET IN GENERAL AND THESE FUNDS IN PARTICULAR? In general, our outlook for the fixed-income markets over the next twelve months remains positive. We believe the U.S. economy is headed for recovery, but one that may take longer and see a slower pace of growth than some are now predicting. We believe inflation and interest rates should remain relatively low over the near term, and we think new municipal issuance should continue to be strong. We anticipate the demand for tax-exempt municipal bonds will remain firm as investors look for ways to rebalance their portfolios and reduce risk. Over the next six months, we plan to keep Fund durations at about their present levels as we continue to focus on adding value whenever possible. We will be looking very closely at insured California and New York bonds, since these states traditionally are large issuers and their insured bonds often can provide added value when compared with insured bonds from other states. Looking at NVG specifically, we expect to complete the investing process for the Fund's MuniPreferred(R) shares and, going forward, will look to manage this new Fund in a manner that is very consistent with the strategies we use for the other insured Funds. Overall, we believe all of these Funds will continue to play an important role in investors' long-range financial programs, providing balance and diversification, dependable tax-free income, quality investments, and a measure of security in uncertain times. 3 Nuveen Insured Quality Municipal Fund, Inc.

THE NUVEEN INVESTOR BOND SURVEILLANCE - A HIGH PRIORITY AT NUVEEN The Enron scandal has raised numerous questions about the real value of American securities. Investors want to know what safeguards are in place to inspire their trust and ensure their holdings are dependable. The Nuveen Investor recently spoke with David Blair, Assistant Vice President and Senior Analyst at Nuveen, about the research and surveillance processes used for Nuveen funds. HOW DO NUVEEN'S RESEARCH ANALYSTS EVALUATE BONDS PRIOR TO PURCHASE? We evaluate factors impacting market sectors, issuers and specific bonds and assign credit ratings to bonds we consider for purchase. We seek to purchase bonds with stable and improving credit characteristics, which have attractive prices and yields relative to other bonds in their sectors. HOW DO YOU CONDUCT YOUR RESEARCH? We conduct detailed analyses that often involve site visits and discussions with managers of the projects being financed. Since Nuveen is a major investor with large buying power, issuers and project managers are willing to listen to us and respond to our concerns. IS THE RESEARCH AND ANALYSIS PROCESS ANY DIFFERENT WHEN CONSIDERING HIGH-YIELD BONDS? Up to 20 percent of some funds can be invested in below investment grade bonds to help the fund attain a higher yield. This underscores the need for research. If one of our 16 analysts believes a high-yield bond should be purchased, a second analyst reviews the issue as well. HOW DO YOU MONITOR THE VARIOUS BONDS ONCE THEY'VE BEEN PURCHASED? We have a proprietary database with information and analysis on the bonds Nuveen holds in its funds. Among other things, we are able to evaluate risk exposure to sectors, issuers and specific bonds on an on-going basis. HOW DOES THE RESEARCH DEPARTMENT COMMUNICATE THE INFORMATION GATHERED? We conduct biweekly meetings within the research department and weekly meetings with portfolio managers. We also write-up our findings and distribute them with "buy," "hold" or "sell" recommendations to portfolio managers.

Significant stock market losses in recent history have sent many investors toward bonds as a way to potentially cut their losses and balance equity-dominated portfolios. While many consider bonds a set-and-forget investment, there are several circumstances that might prompt you to reassess -- and perhaps revamp -- your bond holdings. TAX BRACKET CHANGES The Economic Growth and Tax Relief Reconciliation Act of 2001 has dropped tax brackets a percentage point this year, but a higher salary, large bonus, sale of assets or retirement may push you into a higher tax bracket for 2002. If you are in a higher tax bracket and want to generate an income stream without raising your tax burden, tax-free municipal bonds may be a prudent option. Even if you are in a lower tax bracket, municipal bonds could make sense. The question is whether municipal or taxable bonds will deliver a better taxable yield. RETIREMENT PLANS CHANGE Whether you are near retirement or are currently enjoying it, you may want to consider rebalancing your retirement accounts with less stock and more bonds, to potentially reduce risk and try to preserve the assets that you have accumulated. If you are just entering retirement you may want to make tax-free municipal bonds a part of your portfolio to emphasize income generation and protection from taxation. RISK TOLERANCE CHANGES The recent market volatility and market downturn may have caused many investors to reevaluate their tolerance for risk. On the other hand, your portfolio might have performed well over the last few years and you may not need to take on extra risk to meet your long-term goals. In either situation you could take a look at your bond portfolio and determine whether you need to make changes to correspond with your tolerance for risk. PORTFOLIO CHANGES If you make significant changes to one or more of your investments, you'll want to look at your portfolio as a whole, particularly with regard to overall asset allocation. You may need to do some rebalancing to stay on track with your investment strategy. Your financial advisor can help. Regardless of how your circumstances change, he or she can provide up-to-date information on the bond market and various funds to help you decide how to maximize your returns consistent with your short- and long-term financial goals. No investment is risk free and some investments carry more risk than others. It is important to know what the risks are, to evaluate them against any potential rewards, and to determine your tolerance for risk when selecting an investment.

According to research conducted for the Forum for Investor Advice*, that's the number one reason many turn to a financial advisor. They want someone to suggest ideas and provide consultation, dialogue and professional advice. Investors say their advisors are helpful in other key ways, including... o Saving time. After consultation, investors note that the second most important reason for using an advisor is to have someone else monitor their portfolio, reducing the amount of time they spend on investing. o Help in sorting through information. Investors in the 21st century have more products from which to choose than in the past. For example, there are approximately 8,000 mutual funds today, up from 3,000 in 1990. o Assistance in setting financial goals. According to investors who use a financial advisor, they are more likely to have a plan for a specific financial goal than do-it-yourself investors. o Staying focused. Advisor-assisted investors are more likely than do-it-yourself investors to have developed a comprehensive investment program. o Peace of mind. Investors say their comfort level in all types of markets is higher when using an advisor for a "second opinion" on an investment decision. *The survey of 324 investors was conducted in December of 2000 by Market Facts and analyzed by New York based Neuwirth Research. Of the 324, 166 said they had an ongoing relationship with a financial advisor, while 157 described themselves as do-it-yourselfers. -------------------------------------------------------------------------------- (continued from page 9) HOW ARE PROBLEM BONDS IDENTIFIED AND HANDLED? We conduct surveillance on our bonds on a regular basis to ensure, among other things, that deteriorating bonds are identified early. We then discuss any emerging problems and potential courses of action with the portfolio manager. HOW MANY ISSUES DOES THE RESEARCH DEPARTMENT FOLLOW? We follow 12 sectors and 1,500 uninsured bonds, worth about $18 billion of Nuveen's $45 billion in total municipal assets. The remaining $27 billion in municipal assets are insured or escrowed (backed by Treasury bonds). For the insured bonds, we monitor closely on a regular basis the insurers guaranteeing the bonds. WILL RESEARCH AND SURVEILLANCE CHANGE IN LIGHT OF PROBLEMS WITH ENRON SECURITIES? Overall, our investment process and surveillance have worked well and been effective. However, we meet as a group on a regular basis and are constantly evaluating ways to improve the process to respond to issues and the market environment.

GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES The National Funds (the "Funds") covered in this report 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) and Nuveen Insured Dividend Advantage Municipal Fund (NVG). 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 Insured Dividend Advantage (NVG) is traded on the American Stock Exchange. Prior to the commencement of operations of Insured Dividend Advantage (NVG), 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 The John Nuveen Company, and the recording of the organization expenses ($11,500) and its reimbursement by Nuveen Investments, also a wholly owned subsidiary of The John Nuveen Company. Each Fund seeks to provide current income exempt from regular federal income tax by investing primarily in a diversified portfolio of municipal obligations issued by state and local government authorities. The Funds are registered under the Investment Company Act of 1940 as closed-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 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 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 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 in a separate account with a current value at least equal to the amount of the when-issued and delayed delivery purchase commitments. At April 30, 2002, Insured Quality (NQI), Insured Opportunity (NIO) and Insured Dividend Advantage (NVG) had outstanding when-issued purchase commitments of $35,899,561, $39,897,055 and $61,424,254, respectively. There were no such outstanding purchase commitments in either of the other Funds. Investment 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 for financial reporting purposes. 46 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, to retain such tax-exempt status when distributed to shareholders of the Funds. Dividends and Distributions to Shareholders Tax-exempt net investment income is declared monthly as a dividend. Generally, payment is made or reinvestment is credited to shareholder accounts on the first business day after month-end. Net realized capital gains and/or market discount from investment transactions, if any, are distributed to shareholders not less frequently than annually. Furthermore, capital gains are distributed only to the extent they exceed available capital loss carryforwards. Distributions to shareholders of tax-exempt net investment income, net realized capital gains and/or market discount are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States. Accordingly, temporary over-distributions as a result of these differences may occur and will be classified as either distributions in excess of net investment income, distributions in excess of net realized gains and/or distributions in excess of net ordinary taxable income from investment transactions, where applicable. Preferred Shares The following 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 by the auction agent. The number of Preferred shares outstanding, by Series and in total, for each Fund is as follows: PREMIER INSURED INSURED INSURED INSURED PREMIUM QUALITY OPPORTUNITY INCOME INCOME 2 (NQI) (NIO) (NIF) (NPX) ---------------------------------------------------------------------------------------------------------- Number of shares: Series M 2,600 4,000 -- 2,080 Series T 2,600 4,000 -- 2,200 Series W 2,600 4,000 840 2,080 Series W2 -- 3,200 -- -- Series Th 2,320 4,000 2,800 2,200 Series Th2 -- 4,000 -- -- Series F 2,600 4,000 2,800 2,196 ---------------------------------------------------------------------------------------------------------- Total 12,720 27,200 6,440 10,756 ========================================================================================================== Effective May 17, 2002, Insured Dividend Advantage (NVG) issued 3,160 Series M, 3,080 Series T and 3,080 Series Th, $25,000 stated value Preferred shares. Insurance The Funds 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. 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 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' 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. 47 Notes to Financial Statements (Unaudited) (continued) 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 period ended April 30, 2002. 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 has agreed to pay all offering costs (other than the sales load) that exceed $.03 per Common share for Insured Dividend Advantage (NVG). Insured Dividend Advantage's (NVG) share of offering costs ($801,000) was recorded as a reduction of the proceeds from the sale of Common shares. 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. Change in Accounting Policy As required, effective November 1, 2001, the Funds have adopted the provisions of the new AICPA Audit and Accounting Guide for Investment Companies and began accreting taxable market discount on debt securities. Prior to November 1, 2001, the Funds did not accrete taxable market discount on debt securities until they were sold. The cumulative effect of this accounting change had no impact on the total net assets applicable to Common shares or the Common share net asset values of the Funds, but resulted in an increase in the cost of securities and a corresponding decrease in net unrealized appreciation based on securities held by the following Funds on November 1, 2001, as follows: PREMIER INSURED INSURED INSURED INSURED PREMIUM QUALITY OPPORTUNITY INCOME INCOME 2 (NQI) (NIO) (NIF) (NPX) --------------------------------------------------------- $587,906 $731,003 $23,039 $104,458 --------------------------------------------------------- The effect of this change for the six months ended April 30, 2002, was to increase investment income with a corresponding decrease in net unrealized appreciation as follows: PREMIER INSURED INSURED INSURED INSURED PREMIUM QUALITY OPPORTUNITY INCOME INCOME 2 (NQI) (NIO) (NIF) (NPX) ---------------------------------------------------------- $57,759 $123,309 $9,277 $17,879 ---------------------------------------------------------- The Statement of Changes in Net Assets and Financial Highlights for the prior periods have not been restated to reflect this change in presentation. 48 Classification and Measurement of Redeemable Securities Effective November 1, 2001, the Funds have adopted the classification requirement of EITF D-98, Classification and Measurement of Redeemable Securities. EITFD-98 requires that Preferred shares, at liquidation value, be presented separately in the Statement of Assets and Liabilities. Accordingly, certain reclassifications have been made to the financial statements and financial highlights for all prior periods presented. The adoption of EITF D-98 had no impact on the Funds' Common share net asset values. 2.

NUVEEN EXCHANGE-TRADED FUNDS DIVIDEND REINVESTMENT PLAN Your Nuveen 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. 56 Fund Information BOARD OF DIRECTORS Robert P.
