Schwertfeger Chairman of the Board Chairman's Letter to Shareholders Once again, I am pleased to report that over the six-month period covered by this semiannual report your Fund continued to provide you with monthly tax-free income and an attractive total return. For more details about the management strategy and performance of your Fund, please see the Portfolio Managers' Comments and Performance Overview sections of this report. As I noted in my last letter to you, our conversations with financial advisers and investors suggest that many of you may be wondering whether longer-term interest rates will soon begin to rise substantially, mirroring the rise that has taken place over the past year in shorter-term rates. If longer-term rates do begin to rise significantly, some of you also may be wondering if that makes this a good time to adjust your holdings of fixed-income investments. We can't answer these questions for you - no one knows what the future will bring. "In fact, a well-diversified portfolio may actually help to reduce your overall investment risk." From our experience, we do know that a well-balanced portfolio, structured and carefully monitored with the help of a trusted investment professional, can be an important component in helping you achieve your long-term financial goals. In fact, a well-diversified portfolio may actually help to reduce your overall investment risk. That is one reason why we believe that a municipal bond investment like your Nuveen Fund can be an important building block in a comprehensive investment program designed to perform well in a variety of market conditions. As in past reports, I urge you to 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 - see the inside front cover of this report for instructions. Some of you may have heard that in April, 2005, The St. Paul Travelers Companies, Inc., which owned 79% of Nuveen Investments, Inc. (the parent of your Fund's investment adviser) completed a public offering of a substantial portion of its equity stake in Nuveen. At the same time, St. Paul Travelers also entered into agreements to sell the balance of its shares in Nuveen to us or to others at a future date. These transactions will have no impact on the investment objectives or management of your Fund. However, taken as a whole they are considered to be an "assignment" of your Fund's investment management agreement. This means that you and your fellow Fund shareholders soon will be asked to formally approve the continuation of your Fund's management contract with Nuveen. We will be sending you more information about this process in the coming weeks. At Nuveen Investments, our mission continues to be to assist you and your financial advisor by offering investment services and products that can help you to secure your financial objectives. We are grateful that you have chosen us as a partner as you pursue your financial goals, and 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, 2005 Nuveen Investments Municipal Closed-End Exchange-Traded Funds NPI, NPM, NPT Portfolio Managers' Comments Portfolio managers Dan Solender and Tom Spalding review key investment strategies and the semiannual performance of these three Funds. With thirteen years of investment experience, including nine at Nuveen, Dan assumed portfolio management responsibility for NPI and NPM in 2003. A 30-year veteran of Nuveen, Tom has managed NPT since 2003. WHAT KEY STRATEGIES WERE USED TO MANAGE THESE FUNDS DURING THE SIX MONTHS ENDED APRIL 30, 2005? Between November 2004 and April 2005, the Federal Reserve introduced four quarter-point increases in the fed funds rate, raising this short-term rate benchmark from 1.75% to 2.75%. (On May 3, 2005, following the end of this reporting period, the Fed announced another 0.25% hike, bringing the fed funds rate to 3.00%.) Given these short-term rate increases, many market participants expected to see steadily higher interest rates across most of the municipal market yield curve as we moved through the reporting period. This did not occur, as longer-term yields (as measured by the widely-followed Bond Buyer 25 Revenue Municipal Bond Index) declined by 14 basis points during the six-month period. As a result, the municipal yield curve flattened. In this environment, our focus for each of these Funds remained on a strategy we have employed for the past few years - finding and holding bonds that, in our judgment, would add immediate value to the Funds' portfolios and that could also perform well under a variety of future market scenarios. In general, our purchase activity during this period concentrated on bonds in the long-intermediate part of the yield curve, that is, bonds that mature in about 20 years. In our opinion, this part of the municipal market yield curve often offered more attractive opportunities and better values than bonds with longer or shorter maturities. In addition, buying bonds in this segment of the curve helped improve the overall effective maturity positioning of NPI and NPM by replacing or counterbalancing these Funds' relatively large holdings of bonds with effective maturities of less than 10 years. Since many of these shorter effective maturity bonds were priced to early call dates, this purchase strategy also helped us to diversify the call exposure of the Funds. We also sought to keep the Funds fully invested. This was helped by the strong supply of municipal bonds during this reporting period. For the six months ended April 2005, municipal issuance nationwide totaled approximately $187.7 billion, up 8.6% from the six months ended April 2004. One of the major drivers of the increased supply during this current period was a significant growth in the number of refundings, as issuers sought to take advantage of relatively low current interest rates. Overall, the percentage of insured and higher credit quality securities that came to market during this period was greater than typically seen. As a result, many of our new purchases over this six-month period were bonds that were rated AAA or AA. Although the market provided fewer opportunities in the lower-rated investment-grade categories, we did seek to maintain or augment the Fund's holdings at this end of the quality 2 spectrum when attractive occasions arose. This generally benefited all the Funds, as lower-rated bonds often were among the best performers during this reporting period. Many of these portfolio additions were made with the proceeds from sales of pre-refunded bonds, which tended to underperform in the interest rate environment of the past six months. In looking for new additions to the portfolios of NPI and NPM, we sought bonds with premium prices - that is, bonds trading above their par value because they have coupons greater than current coupon levels. Historically, these bonds have tended to hold their value better than current coupon bonds when interest rates rise. When possible, we purchased bonds issued within states like New York, California, Michigan and Florida where investors typically show strong, consistent demand for municipal bonds. We believe this historically strong demand, regardless of the economic or interest rate environment, may provide more price support over time for the bonds in the Funds' portfolios, and also provide for enhanced liquidity if opportunities arise to sell the securities at attractive prices. HOW DID THE FUNDS PERFORM? Individual results for these Funds, as well as for a comparative index and average, are presented in the accompanying table. TOTAL RETURNS ON NET ASSET VALUE* For periods ended 4/30/05 6-Month 1-Year 5-Year 10-Year -------------------------------------------------------------------------------- NPI 3.37% 10.63% 8.74% 6.73% -------------------------------------------------------------------------------- NPM 3.19% 11.31% 8.33% 7.59% -------------------------------------------------------------------------------- NPT 4.14% 12.20% 6.87% 6.61% -------------------------------------------------------------------------------- Lehman Brothers Municipal Bond Index(1) 1.93% 6.82% 7.04% 6.48% -------------------------------------------------------------------------------- Lipper General Leveraged Municipal Debt Funds Average(2) 3.83% 10.67% 8.98% 7.17% -------------------------------------------------------------------------------- *Six-month returns are cumulative; returns for one year, five years, and ten years are annualized. Past performance is not predictive of future results. Current performance may be higher or lower than the data shown. Returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the sale of Fund shares. For additional information, see the individual Performance Overview for your Fund in this report. For the six months ended April 30, 2005, the cumulative returns on net asset value (NAV) for all three of the Funds covered in this report outperformed the return on the Lehman Brothers Municipal Bond Index. NPT also outperformed the average return for the Lipper peer group, while NPI and NPM trailed this measure. One of the primary factors benefiting the six-month performance of these Funds relative to that of the unmanaged, unleveraged Lehman Brothers index was the Funds' use of financial leverage. While leveraging can add volatility to the Funds' NAVs and share prices, especially during periods of rising interest rates, this strategy can also provide (1) The Lehman Brothers Municipal Bond Index is an unleveraged, unmanaged national index comprising a broad range of investment-grade municipal bonds. Results for the Lehman index do not reflect any expenses. (2) The Lipper General 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, 67 funds; 1 year, 67 funds; 5 years, 51 funds; and 10 years, 46 funds. Fund and Lipper returns assume reinvestment of dividends. 3 opportunities for additional income and total returns for common shareholders when short-term interest rates remain relatively low and long-term rates fall or remain fairly constant, as they did during this reporting period. As noted earlier, the municipal market yield curve flattened over the course of the reporting period. As a result, the prices of bonds with longer maturities generally tended to perform better than those of securities with shorter maturities. This benefited the performance of NPT, which had more exposure to the longer end of the yield curve than NPI or NPM. The relative exposures to longer and shorter effective maturity bonds among these Funds accounted for much of the performance differential between them over these six-months. The flattening of the yield curve during this period also reflected an environment in which many issuers found refundings more economically feasible. This led to an increase in escrowed and pre-refunded holdings, especially in NPI and NPM. The performance of the Funds was boosted by the price appreciation and enhanced credit quality accompanying these advance refundings. At the same time, however, the Funds' holdings of older pre-refunded bonds tended to underperform the general municipal market during this period due primarily to their shorter effective maturities. All of the Funds also benefited from their allocations of lower quality bonds during this period, with bonds rated BBB generally outperforming other credit quality sectors as the demand for these bonds increased. Among the lower-rated holdings making positive contributions to the Funds' cumulative six-month returns were hospital bonds, as the healthcare sector ranked second in terms of performance among the Lehman municipal revenue sectors for the period. In addition, bonds backed by the 1998 master tobacco settlement agreement also produced solid performance during this period, as the litigation environment improved and increased demand drove tobacco bond prices higher. As of April 30, 2005, NPT held approximately 5% of its portfolio in tobacco bonds, while NPI and NPM held just over 2% of their portfolios in these types of bonds. Zero coupon bonds as a group outperformed the general municipal market during this six-month period, and the performance of NPM was helped by its holdings in this category. HOW WERE THE FUNDS POSITIONED IN TERMS OF CREDIT QUALITY AND BOND CALLS AS OF APRIL 30, 2005? Even though lower quality bonds performed well over this period, we continued to believe that in the current geopolitical and economic climate it was important to maintain strong credit quality. As of April 30, 2005, all three of these Funds continued to offer excellent credit quality, with allocations of bonds rated AAA/U.S. guaranteed and AA ranging from 75% in NPM to 77% in NPI and 81% in NPT. At the end of April 2005, potential call exposure for the period May 2005 through the end of 2006 ranged from 9% in NPI to 11% in NPM and 12% in NPT. The number of actual bond calls in all of these Funds depends largely on future market interest rates. 4 Dividend and Share Price INFORMATION All three Funds in this report use leverage to enhance opportunities for additional income for common shareholders. 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, leveraged Funds generally pay lower dividends to MuniPreferred shareholders, which can leave more earnings to support common share dividends. However, when short-term interest rates rise, as they did during this reporting period, the Funds' borrowing costs also rise. While leveraging can still provide benefits for common shareholders as short-term rates rise, the extent of the benefit may be less. In addition, any reinvested proceeds from bonds called or retired during this period were reinvested in a low interest rate environment, which also tended to reduce the income generated by the Funds. The combination of these two factors led to a dividend reduction in NPI, NPM and NPT over the six-month period ended April 30, 2005. Due to capital gains generated by normal portfolio activity, common shareholders of NPM received a long-term capital gain distribution of $0.0971 per share and a net ordinary income distribution of $0.0029 per share at the end of December 2004. All of the Funds in this report 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 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, 2005, all of the Funds in this report had positive UNII balances for both financial statement and tax purposes. At the end of the reporting period, the Funds' share prices were trading at discounts to their NAVs as shown in the accompanying chart: 4/30/05 6-MONTH AVERAGE DISCOUNT DISCOUNT -------------------------------------------------------------------------------- NPI -6.50% -7.41% -------------------------------------------------------------------------------- NPM -8.94% -8.07% -------------------------------------------------------------------------------- NPT -10.10% -9.11% -------------------------------------------------------------------------------- 5 Nuveen Premium Income Municipal Fund, Inc.

The Adviser determined that it was likely United would not remain current on their interest payment obligations with respect to these bonds and thus has stopped accruing interest.

The Fund will continue to treat coupon payments as tax-exempt income until such time that it is formally determined that the interest on the bonds should be treated as taxable.

accompanying notes to financial statements. 44 Notes to Financial Statements (Unaudited) 1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES The funds (the "Funds") covered in this report and their corresponding Common share New York Stock Exchange symbols are Nuveen Premium Income Municipal Fund, Inc. (NPI), Nuveen Premium Income Municipal Fund 2, Inc. (NPM) and Nuveen Premium Income Municipal Fund 4, Inc. (NPT). The Funds are registered under the Investment Company Act of 1940, as amended, as closed-end, diversified management investment companies. 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. Effective January 1, 2005, Nuveen Advisory Corp. ("NAC"), the Funds' previous Adviser, and its affiliate, Nuveen Institutional Advisory Corp. ("NIAC"), were merged into Nuveen Asset Management ("NAM"), each wholly owned subsidiaries of Nuveen Investments, Inc. ("Nuveen"). As a result of the merger, NAM is now the Adviser to all funds previously advised by either NAC or NIAC. The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements in accordance with U.S. generally accepted accounting principles. Investment 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. When price quotes are not readily available (which is usually the case for municipal securities), the pricing service or, in the absence of a pricing service for a particular security, the Board of Directors of the Funds, or its designee, may establish fair market value using a wide variety of market data including yields or prices of municipal bonds of comparable quality, type of issue, coupon, maturity and rating, market quotes or indications of value from securities dealers, evaluations of anticipated cash flows or collateral, general market conditions and other information and analysis, including the obligor's credit characteristics considered relevant by the pricing service or the Board of Directors' designee. 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 transactions are determined on the specific identification method. Securities purchased on a when-issued or delayed delivery basis may have extended settlement periods. Any 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, 2005, Premium Income (NPI) and Premium Income 4 (NPT) had outstanding when-issued purchase commitments of $10,624,146 and $2,848,468, respectively. There were no such outstanding purchase commitments in Premium Income 2 (NPM). Investment Income Interest income, which includes the amortization of premiums and accretion of discounts for financial reporting purposes, is recorded on an accrual basis. Investment income also includes paydown gains and losses, if any. Professional Fees Professional fees presented in the Statement of Operations consist of legal fees incurred in the normal course of operations, audit fees, tax consulting fees and, in some cases, workout expenditures. Workout expenditures are incurred in an attempt to protect or enhance an investment, or to pursue other claims or legal actions on behalf of Fund shareholders. Legal fee refund presented on the Statement of Operations for Premium Income 4 (NPT) reflects a refund of workout expenditures paid in a prior reporting period. Federal Income Taxes Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all net investment income and net capital gains to shareholders and to otherwise comply with the requirements of Subchapter M of the Internal Revenue Code applicable to regulated investment companies. 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. Net realized capital gains and ordinary income distributions paid by the Funds are subject to federal taxation. 45 Notes to Financial Statements (Unaudited) (continued) 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 U.S. generally accepted accounting principles. Preferred Shares The Funds have issued and outstanding Preferred shares, $25,000 stated value per share, as a means of effecting financial leverage. Each Fund's Preferred shares are issued in more than one Series. The dividend rate on each Series is determined every seven days, pursuant to a dutch auction process overseen by the auction agent, and is payable weekly at the end of each rate period. The number of Preferred shares outstanding, by Series and in total, for each Fund is as follows: PREMIUM PREMIUM PREMIUM INCOME INCOME 2 INCOME 4 (NPI) (NPM) (NPT) ----------------------------------------------------------------------- Number of shares: Series M 3,800 2,000 2,200 Series M2 2,000 -- -- Series T 3,800 3,000 2,000 Series T2 -- -- 1,328 Series W 3,800 2,000 1,680 Series W2 -- -- 520 Series TH 3,800 3,000 2,680 Series F 3,800 2,000 1,800 Series F2 -- 1,880 1,328 ----------------------------------------------------------------------- Total 21,000 13,880 13,536 ======================================================================= 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, 2005. 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. Indemnifications Under the Funds' organizational documents, their Officers and Directors 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. However, the Funds have not had prior claims or losses pursuant to these contracts and expect the risk of loss to be remote. Use of Estimates The preparation of financial statements in conformity with U.S. 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 applicable to Common shares from operations during the reporting period. Actual results may differ from those estimates. 46 2. FUND SHARES None of the Funds engaged in transactions in their own shares during the six months ended April 30, 2005, nor during the fiscal year ended October 31, 2004. 3. SECURITIES TRANSACTIONS Purchases and sales (including maturities) of investments in long-term municipal securities during the six months ended April 30, 2005, were as follows: PREMIUM PREMIUM PREMIUM INCOME INCOME 2 INCOME 4 (NPI) (NPM) (NPT) -------------------------------------------------------------------------------------------------- Purchases $ 108,802,903 $ 46,284,902 $ 54,765,439 Sales and maturities 106,019,291 39,284,937 46,587,106 ================================================================================================== 4. INCOME TAX INFORMATION The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to the treatment of paydown gains and losses on investments, timing differences in recognizing income on taxable market discount securities and timing differences in recognizing certain gains and losses on security transactions. At April 30, 2005, the cost of investments was as follows: PREMIUM PREMIUM PREMIUM INCOME INCOME 2 INCOME 4 (NPI) (NPM) (NPT) -------------------------------------------------------------------------------------------------- Cost of investments $1,401,668,396 $911,832,331 $864,254,639 ================================================================================================== Gross unrealized appreciation and gross unrealized depreciation of investments at April 30, 2005, were as follows: PREMIUM PREMIUM PREMIUM INCOME INCOME 2 INCOME 4 (NPI) (NPM) (NPT) -------------------------------------------------------------------------------------------------- Gross unrealized: Appreciation $ 91,147,755 $ 57,960,559 $ 55,169,835 Depreciation (9,994,964) (334,901) (3,257,284) Net unrealized appreciation of investments $ 81,152,791 $ 57,625,658 $ 51,912,551 ================================================================================================== The tax components of undistributed net investment income and net realized gains at October 31, 2004, the Funds' last fiscal year end, were as follows: PREMIUM PREMIUM PREMIUM INCOME INCOME 2 INCOME 4 (NPI) (NPM) (NPT) -------------------------------------------------------------------------------------------------- Undistributed net tax-exempt income * $ 13,928,174 $ 9,752,477 $ 7,067,130 Undistributed net ordinary income ** 6,449 126,711 157,396 Undistributed net long-term capital gains -- 4,326,397 -- ================================================================================================== * Undistributed net tax-exempt income (on a tax basis) has not been reduced for the dividend declared on October 1, 2004, paid on November 1, 2004. ** Net ordinary income consists of taxable market discount income and net short-term capital gains, if any.

If not applied, the carryforwards will expire as follows: PREMIUM PREMIUM INCOME INCOME 4 (NPI) (NPT) ------------------------------------------------------------------------------ Expiration year: 2008 $ 9,710,067 $ 2,151,015 2009 -- -- 2010 6,203,091 18,079,555 2011 6,263,502 24,792,603 ------------------------------------------------------------------------------ Total $22,176,660 $45,023,173 ============================================================================== 5. MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES As approved by the Board of Directors, effective August 1, 2004, a complex-wide management fee structure was adopted for all funds sponsored by the Adviser, or its predecessor and its affiliates. This fee structure separates each fund's management fee into two components - a complex-level component, based on the aggregate amount of all fund assets managed by the Adviser, and a specific fund-level component, based only on the amount of assets within each individual fund. This pricing structure enables Nuveen fund shareholders to benefit from growth in the assets within each individual fund as well as from growth in the amount of complex-wide assets managed by the Adviser. Under no circumstances will this pricing structure result in a fund paying management fees at a rate higher than would otherwise have been applicable had the complex-wide management fee structure not been implemented. As of May 31, 2005, the complex-level fee rate was .1905%; that is, the funds' effective management fees were reduced by approximately .0095%. Effective August 1, 2004, the annual fund-level fee, payable monthly, for each of the Funds is 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) FUND-LEVEL FEE RATE -------------------------------------------------------------------------------------------------------- For the first $125 million .4500% For the next $125 million .4375 For the next $250 million .4250 For the next $500 million .4125 For the next $1 billion .4000 For the next $3 billion .3875 For net assets over $5 billion .3750 ======================================================================================================== 48 Effective August 1, 2004, the annual complex-level fee, payable monthly, which is additive to the fund-level fee, for all Nuveen sponsored funds in the U.S., is based on the aggregate amount of total fund assets managed as follows: COMPLEX-LEVEL ASSETS(1) COMPLEX-LEVEL FEE RATE ------------------------------------------------------------------------------------------------------- For the first $55 billion .2000% For the next $1 billion .1800 For the next $1 billion .1600 For the next $3 billion .1425 For the next $3 billion .1325 For the next $3 billion .1250 For the next $5 billion .1200 For the next $5 billion .1175 For the next $15 billion .1150 For Managed Assets over $91 billion(2) .1400 ======================================================================================================= (1) The complex-level fee component of the management fee for the funds is calculated based upon the aggregate Managed Assets ("Managed Assets" means the average daily net assets of each fund including assets attributable to all types of leverage used by the Nuveen funds) of Nuveen-sponsored funds in the U.S. (2) With respect to the complex-wide Managed Assets over $91 billion, the fee rate or rates that will apply to such assets will be determined at a later date. In the unlikely event that complex-wide Managed Assets reach $91 billion prior to a determination of the complex-level fee rate or rates to be applied to Managed Assets in excess of $91 billion, the complex-level fee rate for such complex-wide Managed Assets shall be .1400% until such time as a different rate or rates is determined. Each Fund paid through July 31, 2004, an annual management fee, payable monthly, at the rates set forth below, which were 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 RATE --------------------------------------------------------------------------------------------------------- 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 ========================================================================================================= 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 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. The Board of Directors has adopted a deferred compensation plan for independent Directors that enables Directors to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from certain Nuveen advised Funds. Under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of select Nuveen advised Funds. 6. ANNOUNCEMENT REGARDING PARENT COMPANY OF ADVISER In early April, 2005, The St. Paul Travelers Companies, Inc. ("St. Paul Travelers"), which owned 79% of Nuveen, (A) completed a public offering of a substantial portion of its equity stake in Nuveen, (B) sold Nuveen $200 million of its Nuveen shares, (C) entered into an agreement with Nuveen to sell an additional $400 million of its Nuveen shares on a "forward" basis with payment for and settlement of these shares delayed for several months, and (D) entered into agreements with two unaffiliated investment banking firms to sell an amount equal to most or all of its remaining Nuveen shares for current payment but for future settlement. The settlement of transactions (C) and (D) above would likely be deemed an "assignment" (as defined in the 1940 Act) of the investment management agreements between the Funds and the Adviser, which would result in the automatic termination of each agreement under the 1940 Act. The Board of Directors will consider approval of new ongoing investment management agreements for each Fund and the submission of those agreements for approval by each respective Fund's shareholders. Those agreements, if approved by a Fund's shareholders, would take effect upon such approval. There can be no assurance that these approvals will be obtained. 7.

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 the 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. FLEXIBLE 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.

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 that would have been necessary each year to equal the investment's actual cumulative performance (including change in NAV or market price and reinvested dividends and capital gains distributions, if any) 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 the expected period over which a bond's principal and interest will be paid, and consequently is a measure of the sensitivity of a bond's or bond Fund's value to changes when market interest rates change. Generally, the longer a bond's 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 longer than the duration of the Fund's portfolio of bonds. 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 common share NAV per share is calculated by subtracting the liabilities of the Fund (including any MuniPreferred shares issued in order to leverage 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. BOARD OF DIRECTORS Robert P.
