Schwertfeger Timothy R. Schwertfeger | Chairman of the Board It is with a variety of emotions that I write my last letter to Nuveen Fund shareholders. For a dozen years, it has been my privilege to communicate periodically with you through these annual and semi-annual reports about the performance and uses of your Fund. Over that time, I've tried to emphasize the central role that quality municipal bonds can play in creating attractive opportunities for current tax-free income, long-term return and portfolio diversification. I firmly believe that all our Fund shareholders, working in conjunction with a trusted financial advisor, have the potential to reach their financial objectives by using Nuveen Funds as a core component of a well-balanced portfolio. As I noted in your Fund's last shareholder report, Nuveen Investments was acquired in November 2007 by a group led by Madison Dearborn Partners, LLC. While this event had no impact on the investment objectives, portfolio management strategies or dividend policies of your Fund, it did provide a convenient point to begin implementing a long-planned transition in the senior management team at Nuveen. As a part of this process, I will be leaving the Board of the Nuveen Funds on June 30, 2008. In addition, Nuveen and your Fund's Board determined that Fund shareholders would be best served by having an independent director serve as the new chairman of the Fund Board. Therefore, I am very excited and pleased to report that I will be succeeded as chairman of your Nuveen Fund Board by Robert Bremner. A member of the Board since 1997, Bob is a management consultant and private investor not affiliated with Nuveen. Over the years, he has played a critical role on the Fund Board, most recently as the lead independent director, and I know Bob and the other Board members are determined to maintain the standards and commitment to quality that you have come to expect from your Nuveen investment. Please take the time to review the Portfolio Manager's Comments, the Common Share Dividend and Share Price Information, and the Performance Overview sections of this report. All of us are grateful that you have chosen Nuveen Investments as a partner as you pursue your financial goals, and, on behalf of Bob Bremner and the other members of your Fund's Board, let me say 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 16, 2008 Portfolio Manager's COMMENTS Nuveen Investments Municipal Closed-End Funds | NPI, NPM, NPT Portfolio manager Paul Brennan reviews key investment strategies and the six-month performance of these three national Funds. With 19 years of industry experience, including 17 years at Nuveen, Paul assumed portfolio management responsibility for the three national Funds in 2006. WHAT KEY STRATEGIES WERE USED TO MANAGE THESE FUNDS DURING THE SIX-MONTH REPORTING PERIOD ENDED APRIL 30, 2008? During this six-month period, the municipal market experienced a great deal of volatility, as issues related to the sub-prime mortgage industry had an indirect but important, influence on the municipal market's performance. Other major factors influencing the municipal market included tighter liquidity stemming from problems in the credit markets, a flight to quality driven by dislocations in the financial markets, and continued uncertainty about municipal bond insurers. We sought to capitalize on this turbulent environment by continuing to focus on relative value, using a fundamental approach to find undervalued sectors and individual credits with the potential to perform well over the long term. As the market discounted bonds that were out of favor, such as those with lower credit quality and higher yields, we took advantage of opportunities that we considered overlooked and undervalued to selectively add these types of bonds to our portfolios, including bonds rated BBB. In addition, we believed that the steepening municipal yield curve began to offer better reward opportunities for purchases made further out on the curve. As a result, many of the additions to our portfolios emphasized longer maturities. Among the credits we added to the Funds were uninsured health care bonds, marking the first time in a while that we found bonds in this sector at attractive levels relative to their credit quality. We also added exposure to the short end of the yield curve by purchasing variable rate demand obligations (VRDOs) at very attractive yields. VRDOs are floating-rate securities that offer interest rates set daily or weekly based on an index of short-term municipal rates. To generate cash for purchases, we selectively sold holdings with shorter durations,(1) including pre-refunded bonds,(2) at attractive prices resulting from high demand. Selling shorter duration bonds and reinvesting further out on the yield curve also helped to Discussions of specific investments are for illustrative purposes only and are not intended as recommendations of individual investments. The views expressed in this commentary represent those of the portfolio manager as of the date of this report and are subject to change at any time, based on market conditions and other factors. The Funds disclaim any obligation to advise shareholders of such changes. (1) Duration is a measure of a bond's price sensitivity as interest rates change, with longer duration bonds displaying more sensitivity to these changes than bonds with shorter durations. (2) Advance refundings, also known as pre-refundings or refinancings, occur when an issuer sells new bonds and uses the proceeds to fund principal and interest payments of older existing bonds. This process often results in lower borrowing costs for bond issuers. 4 improve the Funds' overall call protection profiles. In addition, a number of our new purchases were funded with cash generated by bond redemptions. As noted earlier, over the course of the entire reporting period, we saw the municipal yield curve steepen, as municipal bond interest rates at the short end of the curve declined while longer-term rates rose. In this environment, we continued to emphasize a disciplined approach to duration management. As part of this strategy, we use inverse floating rate securities,(3) a type of derivative financial instrument, in all three of these Funds. Inverse floaters typically provide the dual benefit of lengthening the Funds' durations to be closer to our strategic target and enhancing their income- generation capabilities. Going into this period, NPI, NPM and NPT also used forward interest rate swaps. The goal of this strategy was to help us manage the common share net asset value (NAV) volatility of these Funds without having a negative impact on their income streams or common share dividends over the short term. During this period, we removed the forward interest rate swaps from NPM and NPT. HOW DID THE FUNDS PERFORM? Individual results for these Funds, as well as relevant index and peer group information, are presented in the accompanying table. Total Returns on Common Share Net Asset Value* For periods ended 4/30/08 Six-Month 1-Year 5-Year 10-Year NPI -1.99% -2.52% 4.32% 5.09% NPM -1.94% -2.78% 4.22% 5.20% NPT -1.47% -1.81% 4.43% 4.49% Lipper General Leveraged Municipal Debt Funds Average(4) -2.54% -3.47% 4.64% 5.24% Lehman Brothers Municipal Bond Index(5) 1.47% 2.79% 4.03% 5.16% *Six-month returns are cumulative; returns for one-year, five-year, and ten-year 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. (3) An inverse floating rate security is a financial instrument designed to pay long-term tax-exempt interest at a rate that varies inversely with a short-term tax-exempt interest rate index. For the Nuveen Funds, the index typically used is the Securities Industry and Financial Markets (SIFM) Municipal Swap Index (previously referred to as the Bond Market Association Index or BMA). Inverse floaters, including those inverse floating rate securities in which the Funds invested during this reporting period, are further defined within the Notes to Financial Statements and Glossary of Terms Used in This Report sections of this shareholder report. (4) The Lipper General Leveraged Municipal Debt Funds Average is calculated using the returns of all closed-end funds in this category for each period as follows: six months, 54; 1 year, 54; 5 years, 52; and 10 years, 38. Fund and Lipper returns assume reinvestment of dividends. (5) 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. 5 For the six months ended April 30, 2008, the cumulative returns on NAV for all three of the Funds in this report underperformed the return on the Lehman Brothers Municipal Bond Index. At the same time, the six-month returns for all three Funds outperformed the average return for their Lipper peer group. One of the major factors impacting the six-month performance of these Funds in relation to that of the unleveraged Lehman Brothers Municipal Bond Index was the use of financial leverage. While leverage provides opportunities for additional income and total returns for common shareholders, the benefits of leveraging are tied in part to the short-term rates that leveraged Funds pay their preferred shareholders. During this period, as the yields on longer-term bonds rose and their prices correspondingly fell, declining valuations had a negative effect on performance that was magnified by the use of leverage. In addition, the Funds' borrowing costs remained relatively high, negatively impacting their total returns. (See Recent Developments in the Auction Rate Preferred Markets at the end of this commentary.) Other key factors that influenced the Funds' returns included yield curve and duration positioning, the use of derivatives, credit exposure and sector allocations, and holdings of bonds backed by certain municipal bond insurers. During this six-month period, bonds in the Lehman Brothers Municipal Bond Index with maturities of eight years or less, especially those maturing in two to six years, benefited the most from changes in the interest rate environment. As a result, these shorter maturity bonds generally outperformed credits with longer maturities. Bonds having the longest maturities (22 years and longer) posted the worst returns. As previously noted, one of our strategies during this period focused on adding longer maturity bonds to our portfolios as the yield curve steepened, based on our belief that these bonds offer good long-term potential. This purchase activity helped to extend the Funds' durations, which generally had a negative impact on performance during these past six months. As mentioned earlier, all three Funds used forward interest rate swaps. In these Funds, which had durations that exceeded our strategic target, the interest rate swaps were used to synthetically shorten duration. During this period, in contrast to historical trends, the U.S. Treasury market and the municipal market moved in the opposite 6 directions. As municipal market performance lagged the significant gains made by Treasuries, these derivatives performed poorly, hurting the performance of the three Funds. In addition, the inverse floaters used by all three of these Funds had a negative on performance. This resulted from the fact that the inverse floaters effectively increased the Funds' exposure to longer maturity bonds during a period when shorter maturities were in favor in the market. However, the inverse floaters also benefited the Funds by helping to support their income streams. As credit spreads widened, bonds rated BBB or below posted poor returns. The underperformance of the lower credit quality sector was largely the result of risk- averse investors' flight to quality as disruptions in the financial and housing markets deepened. As of April 30, 2008, the Funds' holdings of bonds rated BBB ranged from approximately 7% in NPT to 12% in NPM. The Funds' allocations to this credit quality sector were generally higher than that of the Lehman Brothers Municipal Bond Index, and the negative impact of this greater exposure to credit risk accounted for some of the performance differential between these Funds and the index. In general, bonds that carried any credit risk, regardless of sector, tended to perform poorly. Revenue bonds as a whole and especially the industrial development and health care sectors that had ranked among the top performers in the Lehman Brothers Municipal Bond Index over the past few years, underperformed the general municipal market. The housing sector also performed poorly, as did lower-rated bonds backed by the 1998 master tobacco settlement agreement. Sectors of the market that generally contributed to the Funds' performances included general obligation bonds, water and sewer, electric utilities, and special tax issues. Pre-refunded bonds performed exceptionally well, due primarily to their shorter effective maturities and higher credit quality. Another factor that had an impact on the performance of these Funds was their position in bonds backed by certain municipal insurers. As concern increased about the balance sheets of municipal bond insurers, prices on bonds insured by these companies declined, detracting from the performance of the Funds. On the whole, the 7 holdings of all of our Funds continued to be well diversified not only between insured and uninsured bonds, but also within the insured bond category. RECENT DEVELOPMENTS REGARDING BOND INSURANCE COMPANIES The portfolios of investments reflect the ratings on certain bonds insured by AMBAC, CIFG, FGIC, MBIA and XLCA as of April 30, 2008. During the period covered by this report, at least one rating agency reduced the rating for AMBAC-insured and MBIA-insured bonds to AA and at least one rating agency further reduced the ratings for FGIC-insured and XLCA-insured bonds to BB. Subsequent to April 30, 2008, and at the time this report was prepared, at least one rating agency further reduced the rating for CIFG-insured bonds to BB and MBIA-insured bonds to A. As of April 30, 2008, at least one rating agency has placed XLCA-insured bonds on "negative credit watch" and one or more rating agencies have placed each of these insurers on "negative outlook", which may presage one or more rating reductions for such insurer or insurers in the future. If one or more insurers' ratings are reduced by these rating agencies, it would likely reduce the effective rating of many of the bonds insured by that insurer or insurers. It is important to note that municipal bonds historically have had a very low rate of default. RECENT DEVELOPMENTS IN THE AUCTION RATE PREFERRED MARKETS Beginning in February 2008, more shares for sale were submitted in the regularly scheduled auctions for the preferred shares issued by these Funds than there were offers to buy. This meant that these auctions "failed to clear'' and that many or all auction preferred shareholders who wanted to sell their shares in these auctions were unable to do so. This decline in liquidity in auction preferred shares did not lower the credit quality of these shares, and auction preferred shareholders unable to sell their shares received distributions at the "maximum rate'' applicable to failed auctions as calculated in accordance with the pre-established terms of the auction preferred shares. At the time this report was prepared, the Funds' managers could not predict when future auctions might succeed in attracting sufficient buyers for the shares offered, if ever. The Funds' managers are working diligently to refund the auction preferred shares, and have made progress in these efforts, but at present there is no assurance that these efforts will succeed. These developments generally do not affect 8 the management or investment policies of these Funds. However, one implication of these auction failures for common shareholders is that the Funds' cost of leverage will likely be higher, at least temporarily, than it otherwise would have been had the auctions continued to be successful. As a result, the Funds' future common share earnings may be lower than they otherwise would have been.

This strategy continued to provide support for the Funds' income streams during this turbulent period. As a result, the dividends of all three of these Funds remained stable throughout the six-month reporting period ended April 30, 2008. Due to capital gains generated by normal portfolio activity, common shareholders of the Funds received capital gains and/or net ordinary income distributions at the end of December 2007 as follows: Short-Term Capital Gains Long-Term Capital Gains and/or Ordinary Income (per share) (per share) NPI -- $0.0009 NPM $0.0215 $0.0040 NPT -- $0.0036 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 common share 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 common share NAV. Each Fund will, over time, pay all of its net investment income as dividends to shareholders. As of April 30, 2008, all three of the Funds in this report had positive UNII balances, based upon our best estimate, for tax purposes and positive UNII balances for financial statement purposes. 10 As of April 30, 2008, the Funds' common share prices were trading at discounts to their common share NAVs as shown in the accompanying chart: 4/30/08 Six-Month Discount Average Discount NPI -7.02% -8.14% NPM -7.05% -8.20% NPT -9.98% -10.72% COMMON SHARE REPURCHASE AND SHARE PRICE INFORMATION On July 10, 2007, the Board of Directors of NPM approved an open market share repurchase program, as part of a broad, ongoing effort designed to support the market prices of the Fund's common shares. Repurchases not only help to support the market price, but because such purchases are made at a discount to NAV, they have the effect of augmenting NAV. Under the terms of the program, NPM may repurchase up to 10% of its outstanding common shares. As of April 30, 2008, NPM had repurchased 297,500 common shares, representing 0.7% of the Fund's total common shares outstanding. 11 NPI Performance OVERVIEW Nuveen Premium Income Municipal Fund, Inc. as of April 30, 2008 Pie Chart: Credit Quality (as a % of total investments(1) AAA/U.S. Guaranteed 58% AA 17% A 14% BBB 9% N/R 2% Bar Chart: 2007-2008 Monthly Tax-Free Dividends Per Share May 0.059 Jun 0.059 Jul 0.059 Aug 0.059 Sep 0.059 Oct 0.059 Nov 0.059 Dec 0.059 Jan 0.059 Feb 0.059 Mar 0.059 Apr 0.059 Line Chart: Share Price Performance -- Weekly Closing Price 5/01/07 14.35 14.41 14.31 14.33 14.21 14.2 13.82 13.63 13.66 13.8 13.83 13.61 13.6 13.55 13.5 13.3 13.23 13.41 13.48 13.95 13.68 13.59 13.61 13.61 13.42 13.36 13.12 13.3 12.8 12.55 12.82 13.12 13.21 12.9 12.71 13.17 13.66 13.87 13.63 13.94 13.79 13.99 13.17 12.68 12.41 13.04 12.96 13.08 13.18 13.22 13.32 13.36 13.26 4/30/08 13.12 FUND SNAPSHOT ------------------------------------ Common Share Price $13.12 ------------------------------------ Common Share Net Asset Value $14.11 ------------------------------------ Premium/(Discount) to NAV -7.02% ------------------------------------ Market Yield 5.40% ------------------------------------ Taxable-Equivalent Yield(2) 7.50% ------------------------------------ Net Assets Applicable to Common Shares ($000) $899,956 ------------------------------------ Average Effective Maturity on Securities (Years) 15.58 ------------------------------------ Leverage-Adjusted Duration 12.13 ------------------------------------ AVERAGE ANNUAL TOTAL RETURN (Inception 7/18/88) ------------------------------------ ON SHARE PRICE ON NAV ------------------------------------ 6-Month (Cumulative) 1.33% -1.99% ------------------------------------ 1-Year -3.37% -2.52% ------------------------------------ 5-Year 3.89% 4.32% ------------------------------------ 10-Year 5.18% 5.09% ------------------------------------ STATES (as a % of total investments) ------------------------------------ California 12.3% ------------------------------------ Texas 9.5% ------------------------------------ New York 9.3% ------------------------------------ Illinois 7.3% ------------------------------------ New Jersey 5.2% ------------------------------------ South Carolina 4.2% ------------------------------------ Florida 3.6% ------------------------------------ Massachusetts 3.1% ------------------------------------ Washington 3.1% ------------------------------------ Minnesota 3.0% ------------------------------------ Colorado 3.0% ------------------------------------ Alabama 2.8% ------------------------------------ Pennsylvania 2.8% ------------------------------------ Louisiana 2.6% ------------------------------------ Nevada 2.6% ------------------------------------ Michigan 2.5% ------------------------------------ District of Columbia 2.3% ------------------------------------ Wisconsin 2.3% ------------------------------------ Other 18.5% ------------------------------------ INDUSTRIES (as a % of total investments) ------------------------------------ U.S. Guaranteed 22.8% ------------------------------------ Tax Obligation/Limited 15.0% ------------------------------------ Health Care 14.7% ------------------------------------ Transportation 11.1% ------------------------------------ Tax Obligation/General 11.1% ------------------------------------ Utilities 6.7% ------------------------------------ Consumer Staples 4.2% ------------------------------------ Other 14.4% ------------------------------------ (1) The percentages shown in the foregoing chart may reflect the ratings on certain bonds insured by AMBAC, CIFG, FGIC, MBIA and XLCA as of April 30, 2008.

GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES 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) (collectively, the "Funds"). 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 or certain U.S. territories. 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 market price quotes are not readily available (which is usually the case for municipal securities), the pricing service may establish fair 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. Prices of forward swap contracts are also provided by an independent pricing service approved by each Fund's Board of Directors. Futures contracts are valued using the closing settlement price, or in the absence of such a price, at the mean of the bid and asked prices. If the pricing service is unable to supply a price for a municipal bond, forward swap or futures contract, each Fund may use market quotes provided by major broker/dealers in such investments. If it is determined that the market price for an investment or derivative instrument is unavailable or inappropriate, the Board of Directors of the Funds, or its designee, may establish fair value in accordance with procedures established in good faith by the Board of Directors. Temporary investments in securities that have variable rate and demand features qualifying them as short-term investments are valued at amortized cost, which approximates market value. Investment Transactions Investment transactions are recorded on a trade date basis. Realized gains and losses from transactions are determined on the specific identification method. Investments purchased on a when-issued/delayed delivery basis may have extended settlement periods. Any investments 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/delayed delivery purchase commitments. At April 30, 2008, there were no such outstanding purchase commitments in any of the 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. Investment income also includes paydown gains and losses, if any. Federal Income Taxes Each Fund is a separate taxpayer for federal income tax purposes. Each Fund intends to distribute substantially all of its 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. 64 Effective April 30, 2008, the Funds adopted Financial Accounting Standards Board (FASB) Interpretation No. 48 "Accounting for Uncertainty in Income Taxes" (FIN 48). FIN 48 provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the financial statements. FIN 48 requires the affirmative evaluation of tax positions taken or expected to be taken in the course of preparing the Funds' tax returns to determine whether it is "more-likely-than-not" (i.e., a greater than 50-percent likelihood) of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold may result in a tax benefit or expense in the current year. Implementation of FIN 48 required management of the Funds to analyze all open tax years, as defined by the statute of limitations, for all major jurisdictions, which includes federal and certain states. Open tax years are those that are open for examination by taxing authorities (i.e., generally the last four tax year ends and the interim tax period since then). The Funds have no examinations in progress. For all open tax years and all major taxing jurisdictions through the end of the reporting period, management of the Funds has reviewed all tax positions taken or expected to be taken in the preparation of the Funds' tax returns and concluded the adoption of FIN 48 resulted in no impact to the Funds' net assets or results of operations as of and during the six months ended April 30, 2008. The Funds are also not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. 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 at least 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 paid by the Funds on each Series is determined every seven days, pursuant to a dutch auction process overseen by the auction agent, and is payable 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 ================================================================================ Beginning in February 2008, more shares for sale were submitted in the regularly scheduled auctions for the Preferred shares issued by the Funds than there were offers to buy. This meant that these auctions "failed to clear,'' and that many Preferred shareholders who wanted to sell their shares in these auctions were unable to do so. Preferred shareholders unable to sell their shares received distributions at the "maximum rate'' applicable to failed auctions as calculated in accordance with the pre-established terms of the Preferred shares. These developments generally do not affect the management or investment policies of the Funds. However, one implication of these auction failures for Common shareholders is that the Funds' cost of leverage will likely be higher, at least temporarily, than it otherwise would have been had the auctions continued to be successful. As a result, the Funds' future Common share earnings may be lower than they otherwise would have been. 65 Notes to FINANCIAL STATEMENTS (continued) (Unaudited) Inverse Floating Rate Securities Each Fund is authorized to invest in inverse floating rate securities. An inverse floating rate security is created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust created by a broker-dealer. In turn, this trust (a) issues floating rate certificates, in face amounts equal to some fraction of the deposited bond's par amount or market value, that typically pay short-term tax-exempt interest rates to third parties, and (b) issues to a long-term investor (such as one of the Funds) an inverse floating rate certificate (sometimes referred to as an "inverse floater") that represents all remaining or residual interest in the trust. The income received by the inverse floater holder varies inversely with the short-term rate paid to the floating rate certificates' holders, and in most circumstances the inverse floater holder bears substantially all of the underlying bond's downside investment risk and also benefits disproportionately from any potential appreciation of the underlying bond's value. The price of an inverse floating rate security will be more volatile than that of the underlying bond because the interest rate is dependent on not only the fixed coupon rate of the underlying bond but also on the short-term interest paid on the floating rate certificates, and because the inverse floating rate security essentially bears the risk of loss of the greater face value of the underlying bond. A Fund may purchase an inverse floating rate security in a secondary market transaction without first owning the underlying bond (referred to as an "externally-deposited inverse floater"), or instead by first selling a fixed-rate bond to a broker-dealer for deposit into the special purpose trust and receiving in turn the residual interest in the trust (referred to as a "self-deposited inverse floater"). A Fund may also enter into shortfall and forbearance agreements (sometimes referred to as a "recourse trust" or "credit recovery swap") with a broker-dealer by which a Fund agrees to reimburse the broker-dealer, in certain circumstances, for the difference between the liquidation value of the fixed-rate bond held by the trust and the liquidation value of the floating rate certificates, as well as any shortfalls in interest cash flows. The inverse floater held by a Fund gives the Fund the right (a) to cause the holders of the floating rate certificates to tender their notes at par, and (b) to have the broker transfer the fixed-rate bond held by the trust to the Fund, thereby collapsing the trust. An investment in an externally-deposited inverse floater is identified in the Portfolio of Investments as an "Inverse floating rate investment". An investment in a self-deposited inverse floater, recourse trust or credit recovery swap is accounted for as a financing transaction in accordance with Statement of Financial Accounting Standards (SFAS) No. 140 "Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities". In such instances, a fixed-rate bond deposited into a special purpose trust is identified in the Portfolio of Investments as an "Underlying bond of an inverse floating rate trust", with the Fund accounting for the short-term floating rate certificates issued by the trust as "Floating rate obligations" on the Statement of Assets and Liabilities. In addition, the Fund reflects in Investment Income the entire earnings of the underlying bond and accounts for the related interest paid to the holders of the short-term floating rate certificates as "Interest expense on floating rate obligations" in the Statement of Operations. During the six months ended April 30, 2008, each Fund invested in externally deposited inverse floaters and/or self-deposited inverse floaters. The average floating rate obligations outstanding and average annual interest rate and fees related to self-deposited inverse floaters during the six months ended April 30, 2008, were as follows: PREMIUM PREMIUM PREMIUM INCOME INCOME 2 INCOME 4 (NPI) (NPM) (NPT) -------------------------------------------------------------------------------- Average floating rate obligations $84,538,393 $58,707,325 $67,893,850 Average annual interest rate and fees 2.96% 2.94% 2.94% ================================================================================ 66 Forward Swap Transactions Each Fund is authorized to invest in forward interest rate swap transactions. Each Fund's use of forward interest rate swap transactions is intended to help the Fund manage its overall interest rate sensitivity, either shorter or longer, generally to more closely align the Fund's interest rate sensitivity with that of the broader municipal market. Forward interest rate swap transactions involve each Fund's agreement with a counterparty to pay, in the future, a fixed or variable rate payment in exchange for the counterparty paying the Fund a variable or fixed rate payment, the accruals for which would begin at a specified date in the future (the "effective date"). The amount of the payment obligation is based on the notional amount of the forward swap contract and the termination date of the swap (which is akin to a bond's maturity). The value of the Fund's swap commitment would increase or decrease based primarily on the extent to which long-term interest rates for bonds having a maturity of the swap's termination date increases or decreases. The Funds may terminate a swap contract prior to the effective date, at which point a realized gain or loss is recognized. When a forward swap is terminated, it ordinarily does not involve the delivery of securities or other underlying assets or principal, but rather is settled in cash on a net basis. Each Fund intends, but is not obligated, to terminate its forward swaps before the effective date. Accordingly, the risk of loss with respect to the swap counterparty on such transactions is limited to the credit risk associated with a counterparty failing to honor its commitment to pay any realized gain to the Fund upon termination. To reduce such credit risk, all counterparties are required to pledge collateral daily (based on the daily valuation of each swap) on behalf of each Fund with a value approximately equal to the amount of any unrealized gain above a pre-determined threshold. Reciprocally, when any of the Funds have an unrealized loss on a swap contract, the Funds have instructed the custodian to pledge assets of the Funds as collateral with a value approximately equal to the amount of the unrealized loss above a pre-determined threshold. Collateral pledges are monitored and subsequently adjusted if and when the swap valuations fluctuate, either up or down, by at least the predetermined threshold amount. Each Fund invested in forward interest rate swap transactions during the six months ended April 30, 2008. Futures Contracts Each Fund is authorized to invest in futures contracts. Upon entering into a futures contract, a Fund is required to deposit with the broker an amount of cash or liquid securities equal to a specified percentage of the contract amount. This is known as the "initial margin." Subsequent payments ("variation margin") are made or received by a Fund each day, depending on the daily fluctuation of the value of the contract. During the period the futures contract is open, changes in the value of the contract are recognized as an unrealized gain or loss by "marking-to-market" on a daily basis to reflect the changes in market value of the contract. When the contract is closed or expired, a Fund records a realized gain or loss equal to the difference between the value of the contract on the closing date and value of the contract when originally entered into. Cash held by the broker to cover initial margin requirements on open futures contracts, if any, is recognized in the Statement of Assets and Liabilities. Additionally, the Statement of Assets and Liabilities reflects a receivable or payable for the variation margin, when applicable. None of the Funds invested in futures contracts during the six months ended April 30, 2008. Risks of investments in futures contracts include the possible adverse movement of the securities or indices underlying the contracts, the possibility that there may not be a liquid secondary market for the contracts and/or that a change in the value of the contract may not correlate with a change in the value of the underlying securities or indices. Zero Coupon Securities Each Fund is authorized to invest in zero coupon securities. A zero coupon security does not pay a regular interest coupon to its holders during the life of the security. Tax-exempt income to the holder of the security comes from accretion of the difference between the original purchase price of the security at issuance and the par value of the security at maturity and is effectively paid at maturity. Such securities are included in the Portfolios of Investments with a 0.000% coupon rate in their description. The market prices of zero coupon securities generally are more volatile than the market prices of securities that pay interest periodically. Custodian Fee Credit Each Fund has an arrangement with the custodian bank whereby certain custodian fees and expenses are reduced by net credits earned on each Fund's cash on deposit with the bank. Such deposit arrangements are an alternative to overnight investments. Credits for cash balances may be offset by charges for any days on which a Fund overdraws its account at the custodian bank. 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. 67 Notes to FINANCIAL STATEMENTS (continued) (Unaudited) 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. 2. FUND SHARES On July 10, 2007, the Board of Directors of Premium Income 2 (NPM) approved an open-market share repurchase program, as part of a broad, ongoing effort designed to support the market prices of the Fund's Common shares. Under the terms of the program, the Fund may repurchase up to 10% of its outstanding Common shares. Transactions in Common shares were as follows: PREMIUM PREMIUM PREMIUM INCOME (NPI) INCOME 2 (NPM) INCOME 4 (NPT) ------------------------ ----------------------- ------------------------ SIX MONTHS SIX MONTHS SIX MONTHS ENDED YEAR ENDED ENDED YEAR ENDED ENDED YEAR ENDED 4/30/08 10/31/07 4/30/08 10/31/07 4/30/08 10/31/07 --------------------------------------------------------------------------------------------------------------------- Common shares repurchased -- -- (4,800) (292,700) -- -- --------------------------------------------------------------------------------------------------------------------- Weighted average price per Common share repurchased -- -- $12.66 $13.65 -- -- Weighted average discount per Common share repurchased -- -- 12.81% 7.30% -- -- ===================================================================================================================== 3. INVESTMENT TRANSACTIONS Purchases and sales (including maturities but excluding short-term investments and derivative transactions) during the six months ended April 30, 2008, were as follows: PREMIUM PREMIUM PREMIUM INCOME INCOME 2 INCOME 4 (NPI) (NPM) (NPT) -------------------------------------------------------------------------------- Purchases $ 60,774,801 $35,741,648 $38,798,913 Sales and maturities 122,873,189 50,229,911 52,629,832 ================================================================================ 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 timing differences in recognizing taxable market discount, timing differences in recognizing certain gains and losses on investment transactions and the treatment of investments in inverse floating rate transactions subject to SFAS No. 140. To the extent that differences arise that are permanent in nature, such amounts are reclassified within the capital accounts on the Statement of Assets and Liabilities presented in the annual report, based on their federal tax basis treatment; temporary differences do not require reclassification. Temporary and permanent differences do not impact the net asset values of the Funds. 68 At April 30, 2008, the cost of investments was as follows: PREMIUM PREMIUM PREMIUM INCOME INCOME 2 INCOME 4 (NPI) (NPM) (NPT) -------------------------------------------------------------------------------- Cost of investments $1,383,613,534 $893,899,398 $857,387,887 ================================================================================ Gross unrealized appreciation and gross unrealized depreciation of investments at April 30, 2008, were as follows: PREMIUM PREMIUM PREMIUM INCOME INCOME 2 INCOME 4 (NPI) (NPM) (NPT) ---------------------------------------------------------------------------------------------------------------------- Gross unrealized: Appreciation $ 49,383,545 $ 33,270,376 $ 32,133,395 Depreciation (32,850,048) (13,553,411) (14,782,658) ---------------------------------------------------------------------------------------------------------------------- Net unrealized appreciation (depreciation) of investments $ 16,533,497 $ 19,716,965 $ 17,350,737 ====================================================================================================================== The tax components of undistributed net tax-exempt income, net ordinary income and net long-term capital gains at October 31, 2007, the Funds' last tax year end, were as follows: PREMIUM PREMIUM PREMIUM INCOME INCOME 2 INCOME 4 (NPI) (NPM) (NPT) -------------------------------------------------------------------------------- Undistributed net tax-exempt income * $4,476,869 $2,091,171 $945,176 Undistributed net ordinary income ** 79,841 231,532 224,239 Undistributed net long-term capital gains -- 1,257,894 -- ================================================================================ * Undistributed net tax-exempt income (on a tax basis) has not been reduced for the dividend declared on October 1, 2007, paid on November 1, 2007. ** 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: October 31, 2008 $ -- $ 355,272 October 31, 2009 -- -- October 31, 2010 -- 18,079,555 October 31, 2011 5,278,911 24,792,603 October 31, 2012 -- -- October 31, 2013 -- 6,161,830 October 31, 2014 4,614,516 806,337 -------------------------------------------------------------------------------- Total $9,893,427 $50,195,597 ================================================================================ 69 Notes to FINANCIAL STATEMENTS (continued) (Unaudited) 5. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES Each Fund's management fee is separated into two components - a complex-level component, based on the aggregate amount of all fund assets managed by Nuveen Asset Management (the "Adviser"), a wholly owned subsidiary of Nuveen Investments, Inc. ("Nuveen"), 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. The annual fund-level fee, payable monthly, for each Fund 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 ================================================================================ 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 stated in the table below. As of April 30, 2008, the complex-level fee rate was .1855%. The complex-level fee schedule is as follows: COMPLEX-LEVEL ASSET BREAKPOINT LEVEL (1) EFFECTIVE RATE AT BREAKPOINT LEVEL -------------------------------------------------------------------------------- $55 billion .2000% $56 billion .1996 $57 billion .1989 $60 billion .1961 $63 billion .1931 $66 billion .1900 $71 billion .1851 $76 billion .1806 $80 billion .1773 $91 billion .1691 $125 billion .1599 $200 billion .1505 $250 billion .1469 $300 billion .1445 ================================================================================ (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 preferred stock issued by or borrowings by the Nuveen funds) of Nuveen-sponsored funds in the U.S. 70 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 its 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. NEW ACCOUNTING PRONOUNCEMENTS Financial Accounting Standards Board Statement on Financial Accounting Standards No. 157 In September 2006, the FASB issued SFAS No. 157, "Fair Value Measurements." This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and requires additional disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The changes to current generally accepted accounting principles from the application of this standard relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurements. As of April 30, 2008, management does not believe the adoption of SFAS No. 157 will impact the financial statement amounts; however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain of the measurements included within the Statement of Operations for the period. Financial Accounting Standards Board Statement of Financial Accounting Standards No. 161 In March 2008, the FASB issued SFAS No. 161, "Disclosures about Derivative Instruments and Hedging Activities." This standard is intended to enhance financial statement disclosures for derivative instruments and hedging activities and enable investors to understand: a) how and why a fund uses derivative instruments, b) how derivative instruments and related hedge items are accounted for, and c) how derivative instruments and related hedge items affect a fund's financial position, results of operations and cash flows. SFAS No. 161 is effective for financial statements issued for fiscal years and interim periods beginning after November 15, 2008. As of April 30, 2008, management does not believe the adoption of SFAS No. 161 will impact the financial statement amounts; however, additional footnote disclosures may be required about the use of derivative instruments and hedging items. 7. SUBSEQUENT EVENTS Distributions to Common Shareholders The Funds declared Common share dividend distributions from their tax-exempt net investment income which were paid on June 2, 2008, to shareholders of record on May 15, 2008, as follows: PREMIUM PREMIUM PREMIUM INCOME INCOME 2 INCOME 4 (NPI) (NPM) (NPT) -------------------------------------------------------------------------------- Dividend per share $.0590 $.0575 $.0485 ================================================================================ Auction Rate Preferred Shares (ARPS) On June 11, 2008, Nuveen announced the Fund Board's approval of plans to use tender option bonds (TOBs), also known as inverse floating rate securities or inverse floaters, to refinance a portion of the funds' outstanding ARPS, whose auctions have been failing for several months, including an initial phase of approximately $1 billion in forty-one funds. Of this amount, Nuveen expects that approximately $560 million in ARPS redemption notices will be issued shortly for thirteen funds, including Premium Income Municipal Fund (NPI), Premium Income Municipal Fund 2 (NPM) and Premium Income Municipal Fund 4 (NPT). 71 Financial HIGHLIGHTS (Unaudited) Selected data for a Common share outstanding throughout each period: Investment Operations Less

A PHONE CALL IS ALL IT TAKES TO SET UP YOUR REINVESTMENT ACCOUNT. NUVEEN CLOSED-END FUNDS DIVIDEND REINVESTMENT PLAN Your Nuveen Closed-End 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 greater of the net asset value or 95% of 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. If the Plan Agent begins purchasing Fund shares on the open market while shares are trading below net asset value, but the Fund's shares subsequently trade at or above their net asset value before the Plan Agent is able to complete its purchases, the Plan Agent may cease open-market purchases and may invest the uninvested portion of the distribution in newly-issued Fund shares at a price equal to the greater of the shares' net asset value or 95% of the shares' market value on the last business day immediately prior to the purchase date. 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. 76 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.

Auctions that fail to attract enough buyers for all the shares offered for sale are deemed to have "failed", with current holders receiving a formula-based interest rate until the next scheduled auction. [] 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 the number of years to maturity of the bonds in a Fund's portfolio, computed by weighting each bond's time to maturity (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 unless an escrow account has been established to redeem the bond before maturity. The market value weighting for an investment in an inverse floating rate security is the value of the portfolio's residual interest in the inverse floating rate trust, and does not include the value of the floating rate securities issued by the trust. [] Inverse Floaters: Inverse floating rate securities are created by depositing a municipal bond, typically with a fixed interest rate, into a special purpose trust created by a broker-dealer. This trust, in turn, (a) issues floating rate certificates typically paying short-term tax-exempt interest rates to third parties in amounts equal to some fraction of the deposited bond's par amount or market value, and (b) issues an inverse floating rate certificate (sometimes referred to as an "inverse floater") to an investor (such as a Fund) interested in gaining investment exposure to a long-term municipal bond. The income received by the holder of the inverse floater varies inversely with the short-term rate paid to the floating rate certificates' holders, and in most circumstances the holder of the inverse floater bears substantially all of the underlying bond's downside investment risk. The holder of the inverse floater typically also benefits disproportionately from any potential appreciation of the underlying bond's value. Hence, an inverse floater essentially represents an investment in the underlying bond on a leveraged basis. [] 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 Preferred 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. [] Zero Coupon Bond: A zero coupon bond does not pay a regular interest coupon to its holders during the life of the bond. Tax-exempt income to the holder of the bond comes from accretion of the difference between the original purchase price of the bond at issuance and the par value of the bond at maturity and is effectively paid at maturity. The market prices of zero coupon bonds generally are more volatile than the market prices of bonds that pay interest periodically. 78 Other Useful INFORMATION QUARTERLY PORTFOLIO OF INVESTMENTS AND PROXY VOTING INFORMATION You may obtain (i) each Fund's quarterly portfolio of investments, (ii) information regarding how the Funds voted proxies relating to portfolio securities held during the twelve-month period ended June 30, 2007, and (iii) a description of the policies and procedures that the Funds used to determine how to vote proxies relating to portfolio securities without charge, upon request, by calling Nuveen Investments toll-free at (800) 257-8787 or on Nuveen's website at www.nuveen.com.
