CHAIRMAN'S LETTER
- -----------------

DEAR FELLOW SHAREHOLDER,

I am pleased to present to you this semi-annual report of the Neuberger Berman
Income Opportunity Fund Inc., for the period ending April 30, 2004. The report
includes portfolio commentary, a listing of the Fund's investments, and its
financial statements for the reporting period.

The Fund's investment objective is to provide high current income through a
diversified portfolio of both real estate securities and high-yield bonds.

Portfolio Co-Manager Steven Brown manages the real estate portion of the Fund.
His investment approach combines analysis of security fundamentals and real
estate with property sector diversification. His disciplined valuation
methodology seeks out real estate securities that are attractively priced
relative to their historical growth rates and the valuation of other property
sectors.

Portfolio Co-Manager Wayne Plewniak manages the high-yield bond portion of the
Fund. His investment approach focuses on preserving capital, generating income,
and managing risk. He seeks to avoid the default and volatility risk associated
with high-yield bonds by applying rigorous credit analysis to higher-quality
issues, and by emphasizing the intermediate range of the yield curve.

We believe our conservative investing philosophy and disciplined investment
process will benefit you with superior current income over the long term.

Thank you for your confidence in Neuberger Berman. We will continue to do our
best to keep earning it.

Sincerely,


/s/ Peter Sundman

INCOME OPPORTUNITY FUND INC. Portfolio Commentary
- -------------------------------------------------

          For the six-month period ending April 30, 2004, on a Net Asset Value
          (NAV) basis, the Neuberger Berman Income Opportunity Fund Inc.
          (AMEX:NOX) returned 6.10%.

          Although the Fund's history is short, having just begun operations on
          July 2, 2003, we are pleased with its performance thus far. The Fund
          pursues a primary objective of high current income by investing a
          portion of its assets in intermediate-term high-yield corporate bonds
          with maturities of ten years or less at the time of initial investment
          and real estate investment trust (REIT) securities, including REIT
          common stocks and REIT preferred shares.

          At the beginning of the period, the Fund was more heavily weighted
          toward REIT securities, a result of the strong REIT market in 2003.
          The Asset Allocation Committee, which consists of the firm's Chief
          Investment Officer and the Fund's portfolio managers, capitalized on
          this strength during the period, shifting the portfolio's allocation
          to a more even mix of REIT securities and high-yield bonds. As of
          April 30, 2004, the Fund held 32.7% of its investments in REIT common
          stocks, 12.0% in REIT preferred stocks, 42.2% in bonds, and 13.1% in
          cash.

          REAL ESTATE INVESTMENT TRUST HOLDINGS

          REITs posted modestly positive performance for the six months ended
          April 30, 2004. The route to that performance, however, was uneven.
          REITs performed strongly during the five-month period from October
          31st to March 31st, but during the month of April experienced a
          decline of nearly 15%. April's weak REIT performance was primarily due
          to a strong jobs report released early in the month, which sparked
          concern over potentially higher interest rates. The fear of higher
          interest rates led to a sell-off in the bond market and subsequently
          ignited a sell-off in the REIT market.

          In our experience, interest rate changes have not significantly
          affected the performance of REITs over long periods of time.
          Correlation studies over the last five, ten, and twenty-five years
          show a very low correlation between REIT performance and the direction
          of interest rates. In addition, during periods when interest rates
          rose for twelve consecutive months, REITs have historically generated
          positive total returns.

          We believe that REIT valuation levels are currently attractive.
          Although we expect interest rates and inflation to move higher over
          the next twelve months, we also expect GDP growth (Gross Domestic
          Product) to remain robust, employment to accelerate and business
          spending to pick up. In our view, these conditions have the potential
          to enhance the REIT industry's earnings power. New supply growth also
          remains in check and we are beginning to see acceleration in demand.
          In this environment, we continue to have a positive view of the
          potential for REIT stock price performance over the next twelve
          months.

          HIGH-YIELD SECURITIES HOLDINGS

          Given the ongoing improvement in economic activity, a stronger
          employment picture, and continued consumer confidence, we expected
          rates to rise at some point this year. Consequently, we maintained a
          relatively short duration and maturity stance, which we believe helped
          cushion performance. We are also continuing to upgrade the quality of
          the securities in which we invest.

          We would describe the six-month period from October 31, 2003 to April
          30, 2004, as relatively sedate. There were no specific shocks to the
          market or negative surprises among the portfolio's high-yield
          holdings. During the period, new issuance and refinancings remained at
          high levels. Many companies took advantage of the market's window of
          opportunity to restructure their debt. Although the aggregate level of
          debt for these companies (many of which we own) has not declined, the
          average cost of their debt has, providing them with greater financial
          flexibility going forward.

          We may not like the price fluctuations that we see caused by the
          recent adjustment in short-term interest rates, but we are optimistic
          about the expansionary economic period that we believe we are
          entering. In our view, improving economic

                                        2

          conditions are providing the wind at our backs. The Federal Reserve
          Board's actions are being taken to ensure that the economy is not
          overheating, which we believe is a positive for companies in the
          portfolio over the long term.

          Although the backup in interest rates was rather abrupt, we are
          confident that the portfolio is well positioned going forward. We took
          smaller positions in most of the portfolio's longer dated bonds (those
          with relatively lower coupons) and as companies continue to refinance
          or call in their debt, we will look for opportunities to roll those
          securities into higher coupon debt or buy lower-coupon bonds for
          better prices.

          Our investment orientation will remain toward keeping duration
          relatively short. This part of the curve still provides compelling
          income, yet in the past has minimized risks related to rising interest
          rates. We also intend to maintain our focus on credit selection and to
          remain well diversified across industries. Looking ahead, we are
          excited about the opportunities in the high yield market.

          Sincerely,

                    /s/ Steven R. Brown    /s/ Wayne Plewniak

NOTES TO SCHEDULE OF INVESTMENTS
- --------------------------------

          +    Investments in equity securities by the Fund are valued at the
               latest sales price where that price is readily available;
               securities for which no sales were reported, unless otherwise
               noted, are valued at the last available bid price on that day.
               Securities traded primarily on the NASDAQ Stock Market are
               normally valued by the Fund at the NASDAQ Official Closing Price
               ("NOCP") provided by NASDAQ each business day. The NOCP is the
               most recently reported price as of 4:00:02 p.m., Eastern time,
               unless that price is outside the range of the "inside" bid and
               asked prices (i.e., the bid and asked prices that dealers quote
               to each other when trading for their own accounts); in that case,
               NASDAQ will adjust the price to equal the inside bid or asked
               price, whichever is closer. Because of delays in reporting
               trades, the NOCP may not be based on the price of the last trade
               to occur before the market closes. Investments in debt securities
               by the Fund are valued daily by obtaining bid price quotations
               from independent pricing services on all securities available in
               each service's data base. For all other securities requiring
               daily quotations, bid prices are obtained from principal market
               makers in those securities. The Fund values all other securities
               by a method the Board of Directors of the Fund (the "Board")
               believes accurately reflects fair value. Numerous factors may be
               considered when determining the fair value of a security,
               including available analyst, media or other reports, trading in
               futures or ADRs and whether the issuer of the security being fair
               valued has other securities outstanding. Foreign security prices
               are furnished by independent quotation services expressed in
               local currency values. Foreign security prices are translated
               from the local currency into U.S. dollars using the exchange rate
               as of 12:00 p.m., Eastern time. The Board has approved the use of
               FT Interactive Data Corporation ("FT Interactive") to assist in
               determining the fair value of the Fund's foreign equity
               securities in the wake of certain significant events.
               Specifically, when changes in the value of a certain index
               suggest that the closing prices on the foreign exchanges no
               longer represent the amount that the Fund could expect to receive
               for those securities, FT Interactive will provide adjusted prices
               for certain foreign equity securities based on an analysis
               showing historical correlations between the prices of those
               securities and changes in the index. In the absence of precise
               information about the market values of these foreign securities
               as of the close of the New York Stock Exchange, the Board has
               determined on the basis of available data that prices adjusted in
               this way are likely to be closer to the prices the Fund could
               realize on a current sale than are the prices of those securities
               established at the close of the foreign markets in which the
               securities primarily trade. However, fair value prices are
               necessarily estimates, and there is no assurance that such a
               price will be at or close to the price at which the security next
               trades. Short-term debt securities with less than 60 days until
               maturity may be valued at cost which, when combined with interest
               earned, approximates market value.

          #    At cost, which approximates market value.

          ##   At April 30, 2004, the cost of investments for U.S. Federal
               income tax purposes was $425,545,000. Gross unrealized
               appreciation of investments was $11,847,000 and gross unrealized
               depreciation of investments was $4,926,000, resulting in net
               unrealized appreciation of $6,921,000, based on cost for U.S.
               Federal income tax purposes.

NOTES TO FINANCIAL STATEMENTS Income Opportunity Fund Inc.
- ----------------------------------------------------------

               NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

          1    GENERAL: Neuberger Berman Income Opportunity Fund Inc. (the
               "Fund") was organized as a Maryland corporation on April 17, 2003
               as a non-diversified, closed-end management investment company
               under the Investment Company Act of 1940, as amended. The Fund
               had no operations until July 2, 2003, other than matters relating
               to its organization and the sale on June 18, 2003 of 6,981 shares
               of common stock for $100,003 ($14.325 per share) to Neuberger
               Berman, LLC ("Neuberger"), the Fund's sub-adviser. The Board of
               Directors of the Fund may classify or re-classify any unissued
               shares of capital stock into one or more classes of preferred
               stock without the approval of shareholders.

               The preparation of financial statements in accordance with
               accounting principles generally accepted in the United States
               requires Neuberger Berman Management Inc. ("Management") to make
               estimates and assumptions at the date of the financial
               statements. Actual results could differ from those estimates.

          2    PORTFOLIO VALUATION: Investment securities are valued as
               indicated in the notes following the Schedule of Investments.

          3    SECURITIES TRANSACTIONS AND INVESTMENT INCOME: Securities
               transactions are recorded on a trade date basis. Dividend income
               is recorded on the ex-dividend date. Non-cash dividends included
               in dividend income, if any, are recorded at the fair market value
               of the securities received. Interest income, including accretion
               of discount (adjusted for original issue discount, where
               applicable), and amortization of premium, where applicable, is
               recorded on the accrual basis. Realized gains and losses from
               securities transactions and foreign currency transactions are
               recorded on the basis of identified cost and stated separately in
               the Statement of Operations.

          4    FEDERAL INCOME TAXES: It is the policy of the Fund to continue to
               qualify as a regulated investment company by complying with the
               provisions available to certain investment companies, as defined
               in applicable sections of the Internal Revenue Code, and to make
               distributions of investment company taxable income and net
               capital gains (after reduction for any amounts available for U.S.
               Federal income tax purposes as capital loss carryforwards)
               sufficient to relieve it from all, or substantially all, U.S.
               Federal income taxes. Accordingly, the Fund paid no U.S. Federal
               income taxes and no provision for U.S. Federal income taxes was
               required.

          5    DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS: The Fund earns
               income, net of expenses, daily on its investments. It is the
               policy of the Fund to declare quarterly and pay monthly
               distributions to common shareholders. The Fund has adopted a
               policy to pay common shareholders a stable distribution. In an
               effort to maintain a stable distribution amount, distributions
               may consist of net investment income, realized gains and paid-in
               capital. The Fund may pay distributions in excess of those
               required by its stable distribution policy to avoid excise tax or
               to satisfy the requirements of Subchapter M of the Internal
               Revenue Code. Income dividends and capital gain distributions to
               common shareholders are recorded on the ex-dividend date. Net
               realized capital gains, if any, will be offset by capital loss
               carryforwards. Any such offset will not reduce the level of the
               stable distribution paid by the Fund. Dividends and distributions
               to preferred shareholders are accrued and determined as described
               in Note A-7.

NOTES TO FINANCIAL STATEMENTS Income Opportunity Fund Inc. cont'd
- -----------------------------------------------------------------

               The Fund invests a significant portion of its assets in
               securities issued by real estate companies, including real estate
               investment trusts. After calendar year-end, real estate companies
               often recharacterize the nature of the distributions paid during
               that year, frequently with the result that distributions
               previously identified as income are recharacterized as return of
               capital and/or capital gain. As a result, the composition of the
               Fund's distributions as reported herein may differ from the final
               composition determined after calendar year-end and reported to
               Fund shareholders on Form 1099.

               The Fund distinguishes between dividends on a tax basis and a
               financial reporting basis and only distributions in excess of tax
               basis earnings and profits are reported in the financial
               statements as a tax return of capital. Differences in the
               recognition or classification of income between the financial
               statements and tax earnings and profits which result in temporary
               over-distributions for financial statement purposes are
               classified as distributions in excess of net investment income or
               accumulated net realized gains in the components of net assets on
               the Statement of Assets and Liabilities.

               On March 30, 2004, the Fund declared two monthly dividends to
               common shareholders from its net investment income in the amount
               of $0.10625 per share per month, payable after this reporting
               period, on May 28, 2004 and June 30, 2004, to shareholders of
               record on May 14, 2004 and June 14, 2004, respectively, with
               ex-dividend dates of May 12, 2004 and June 10, 2004,
               respectively.

               The tax character of distributions paid during the period ended
               October 31, 2003 was as follows:

</Table>
               As of October 31, 2003, the components of distributable earnings
               (accumulated losses) on a U.S. Federal income tax basis were as
               follows:

<Table>
<Caption>
                    UNDISTRIBUTED   UNDISTRIBUTED       UNREALIZED            LOSS
                         ORDINARY       LONG-TERM     APPRECIATION   CARRYFORWARDS
                           INCOME            GAIN   (DEPRECIATION)   AND DEFERRALS         TOTAL
                                                                          
                    $          --   $          --   $    9,461,070   $          --    $9,461,070
</Table>

               The difference between book basis and tax basis is attributable
               to the timing differences of dividend payments and the
               amortization of bond premium.

          6    EXPENSE ALLOCATION: Some bills are applicable to multiple funds.
               Expenses directly attributable to the Fund are charged to the
               Fund. Expenses borne by the complex of related investment
               companies, which includes open-end and closed-end investment
               companies for which Management serves as investment manager, that
               are not directly attributed to the Fund, are allocated among the
               Fund and the other investment companies in the complex or series
               thereof, on the basis of relative net assets, except where a more
               appropriate allocation of expenses to each investment company in
               the complex or series thereof can otherwise be made fairly.

          7    REDEEMABLE PREFERRED SHARES: On June 5, 2003, the Fund
               re-classified 6,000 unissued shares of capital stock as Series A
               Auction Preferred Shares and Series B Auction Preferred Shares
               ("Preferred Shares"). On September 26, 2003, the Fund issued
               2,510 Series A Auction Preferred Shares and 2,510 Series B
               Auction Preferred Shares. All Preferred Shares have a liquidation
               preference of $25,000 per share plus any accumulated unpaid
               dividends, whether or not earned or declared by the Fund, but
               excluding interest thereon ("Liquidation Value").

               Except when the Fund has declared a special rate period,
               dividends to preferred shareholders, which are cumulative, are
               accrued daily and paid every 7 days. Dividend rates are reset
               every 7 days based on the results of an auction, except during
               special rate periods. For the six months ended April 30, 2004,
               dividend rates ranged from 1.07% to 1.46% for Series A and 1.05%
               to 1.54% for Series B Auction Preferred Shares. The Fund declared
               dividends to preferred shareholders for the period May 1, 2004 to
               May 31, 2004 of $68,103 and $68,286 for Series A and Series B
               Auction Preferred Shares, respectively.

               The Fund may redeem Preferred Shares, in whole or in part, on the
               second business day preceding any dividend payment date at
               Liquidation Value. The Fund is also subject to certain
               restrictions relating to the Preferred Shares. Failure to comply
               with these restrictions could preclude the Fund from declaring
               any distributions to common shareholders or repurchasing common
               shares and/or could trigger the mandatory redemption of Preferred
               Shares at Liquidation Value. The holders of Preferred Shares are
               entitled to one vote per share and, unless otherwise required by
               law, will vote with holders of common stock as a single class,
               except that the Preferred Shares will vote separately as a class
               on certain matters, as required by law. The holders of the
               Preferred Shares, voting as a separate class, are entitled at all
               times to elect two Directors of the Fund, and to elect a majority
               of the Directors of the Fund if the Fund fails to pay dividends
               on Preferred Shares for two consecutive years.

          8    INTEREST RATE SWAPS: The Fund may enter into interest rate swap
               transactions, with institutions that the Fund's investment
               manager has determined are creditworthy, to reduce the risk that
               an increase in short-term interest rates could reduce common
               share net earnings as a result of leverage. The Fund agrees to
               pay the swap counter party a fixed-rate payment in exchange for
               the counter party's paying the Fund a variable-rate payment that
               is intended to approximate all or a portion of the Fund's
               variable-rate payment obligation on the Fund's Preferred Shares.
               The payment flows are netted against each other, with the
               difference being paid by one party to the other. The Fund will
               segregate cash or liquid securities having a value at least equal
               to the Fund's net payment obligations under any swap transaction,
               marked to market daily.

               Risks may arise if the counter party to a swap contract fails to
               comply with the terms of its contract. The loss incurred by the
               failure of a counter party is generally limited to the net
               interest payment to be received by the Fund, and/or the
               termination value at the end of the contract. Additionally, risks
               may arise from movements in interest rates unanticipated by
               Management.

               As a result of SEC staff guidance relating to the application of
               FASB Statement No 133, ACCOUNTING FOR DERIVATIVE INSTRUMENTS AND
               HEDGING ACTIVITIES to registered investment companies, the Fund
               has revised its methodology for accounting for interest rate swap
               agreements. Previously, the Fund

- -----------------------------------------------------------------

               recorded the accrual of the net interest income or expense
               expected to be received or paid at interim settlement dates as a
               net payable or receivable for swap contracts and actual amounts
               paid as net interest income or expense on swap contracts.
               Effective November 1, 2003, periodic expected interim net
               interest payments or receipts on the swaps are recorded as an
               adjustment to unrealized gains/losses, along with the fair value
               of the future periodic payment streams on the swaps. The
               unrealized gains/losses associated with the periodic interim net
               interest payments are reclassified to realized gains/losses in
               conjunction with the actual net receipt or payment of such
               amounts. Upon adoption of this methodology, the Fund recorded a
               cumulative effect adjustment to reflect the reclassification of
               such amounts. The cumulative effect resulted in an increase to
               distributions in excess of net investment income of $40,911, and
               a corresponding decrease to accumulated net realized gains/losses
               as of November 1, 2003. The current year impact increased net
               investment income by $895,262, increased net realized losses by
               $865,445 and decreased unrealized appreciation (depreciation) in
               value of investments by $29,817, and therefore did not impact the
               Fund's total net assets or its total net increase (decrease) in
               net assets applicable to common shareholders resulting from
               operations. At April 30, 2004, the Fund had outstanding interest
               rate swap contracts as follows:

               (1)  30 day LIBOR (London Interbank Offered Rate)

          9    SECURITY LENDING: Pursuant to an Exemptive Order issued by the
               Securities and Exchange Commission, the Fund entered into a
               Securities Lending Agreement ("Agreement") with Neuberger.
               Securities loans involve certain risks in the event a borrower
               should fail financially, including delays or inability to recover
               the lent securities or foreclose against the collateral. The
               investment manager, under the general supervision of the Fund's
               Board of Directors, monitors the creditworthiness of the parties
               to whom the Fund makes security loans. The Fund will not lend
               securities on which covered call options have been written, or
               lend securities on terms which would prevent the Fund from
               qualifying as a regulated investment company. The Fund receives
               cash collateral equal to at least 102% of the current market
               value of the loaned securities. The Fund invests the cash
               collateral in the N&B Securities Lending Quality Fund, LLC, which
               is managed by State Street Bank and Trust Company ("State
               Street") pursuant to guidelines approved by the Fund's investment
               manager. Neuberger guarantees a minimum revenue to the Fund under
               the Agreement, and receives a portion of any revenue earned in
               excess of the guaranteed amount as a lending agency fee. At April
               30, 2004, the Fund had not paid Neuberger any fees under the
               Agreement.

               Income earned on the securities loaned, if any, is reflected in
               the Statement of Operations under the caption Income from
               securities loaned-net.

          10   REPURCHASE AGREEMENTS: The Fund may enter into repurchase
               agreements with institutions that the Fund's investment manager
               has determined are creditworthy. Each repurchase agreement is
               recorded at cost. The Fund requires that the securities purchased
               in a repurchase agreement be transferred to the custodian in a
               manner sufficient to enable the Fund to assert a perfected
               security interest in those securities in the event of a default
               under the repurchase agreement. The Fund monitors, on a daily
               basis, the value of the securities transferred to ensure that
               their value, including accrued interest, is greater than amounts
               owed to the Fund under each such repurchase agreement.

          11   TRANSACTIONS WITH OTHER FUNDS MANAGED BY NEUBERGER BERMAN
               MANAGEMENT INC.: Pursuant to an Exemptive Order issued by the
               Securities and Exchange Commission, the Fund may invest in the
               Neuberger Berman Institutional Cash Fund (the "Cash Fund"), a
               fund managed by Management and having the same Board members as
               the Fund. The Cash Fund seeks to provide as high a level of
               current income as is consistent with the preservation of capital
               and the maintenance of liquidity. For any cash that the Fund
               invests in the Cash Fund, Management waives a portion of its
               management fee equal to the management fee it receives from the
               Cash Fund on those assets. For the six months ended April 30,
               2004, such waived fees amounted to $1,164. For the six months
               ended April 30, 2004, income earned on this investment amounted
               to $9,034 and is reflected in the Statement of Operations under
               the caption Income from investments in affiliated issuers.

          12   ORGANIZATION EXPENSES AND OFFERING COSTS: Management has agreed
               to pay all organizational expenses and the amount by which the
               Fund's offering costs for common stock (other than sales load)
               exceed $0.03 per share. The costs incurred by Management were
               $292,217. Offering costs for common stock paid by the Fund were
               charged as a reduction of common stock paid-in-capital at the
               completion of the Fund's offerings and amounted to $531,709.

               Additionally, offering costs of $397,706 and a sales load of
               $1,255,000 incurred through the issuance of Preferred Shares were
               charged as a reduction of common stock paid-in-capital at the
               completion of the Fund's Preferred Shares offering.

          13   CONCENTRATION OF RISK: Under normal market conditions, the Fund's
               equity investments will be primarily concentrated in
               income-producing common equity securities, preferred securities,
               convertible securities and non-convertible debt securities issued
               by companies deriving the majority of their revenue from the
               ownership, construction, financing, management and/or sale of
               commercial, industrial, and/or residential real estate. The value
               of the Fund's shares may fluctuate more due to economic, legal,
               cultural or technological developments affecting the United
               States real estate industry or a segment of the real estate
               industry in which the Fund owns a substantial position, than
               would the shares of a fund not concentrated in the real estate
               industry. The Fund's debt investments will be primarily
               concentrated in high-yield corporate debt securities rated, at
               the time of investment, Ba or lower by Moody's Investors Service,
               Inc. or BB or lower by Standard & Poor's Corp, or if unrated by
               either of those entities, determined by Management to be of
               comparable quality. Due to the inherent volatility and
               illiquidity of the high yield securities in which the Fund
               invests and the real or perceived difficulty of issuers of those
               high yield securities to meet their payment obligations during
               economic downturns or because of negative business developments

NOTES TO FINANCIAL STATEMENTS Income Opportunity Fund Inc. cont'd
- -----------------------------------------------------------------

               relating to the issuer or its industry in general, the value of
               the Fund's shares may fluctuate more than would be the case if
               the Fund did not concentrate in high yield securities.

               NOTE B--MANAGEMENT FEES, ADMINISTRATION FEES, AND OTHER
               TRANSACTIONS WITH AFFILIATES:

               The Fund retains Management as its investment manager under a
               Management Agreement. For such investment management services,
               the Fund pays Management a fee at the annual rate of 0.60% of its
               average daily Managed Assets. Managed Assets equal the total
               assets of the Fund, less liabilities other than the aggregate
               indebtedness entered into for purposes of leverage. For purposes
               of calculating Managed Assets, the Liquidation Value of any
               Preferred Shares outstanding is not considered a liability.

               Management has contractually agreed to waive a portion of the
               management fees it is entitled to receive from the Fund at the
               following annual rates:

</Table>

               Management has not agreed to waive any portion of its fees beyond
               October 31, 2011.

               For the six months ended April 30, 2004, such waived fees
               amounted to $500,852.

               The Fund retains Management as its administrator under an
               Administration Agreement. The Fund pays Management an
               administration fee at the annual rate of 0.25% of its average
               daily Managed Assets under this agreement. Additionally,
               Management retains State Street as its sub-administrator under a
               Sub-Administration Agreement. Management pays State Street a fee
               for all services received under the agreement.

               On October 31, 2003, Management and Neuberger, a member firm of
               the New York Stock Exchange and sub-adviser to the Fund, became
               indirect wholly owned subsidiaries of Lehman Brothers Holdings
               Inc. ("Lehman"), a publicly-owned holding company ("the
               Transaction"). Upon completion of the Transaction, the Fund's
               management and sub-advisory agreements automatically terminated.
               To provide for continuity of management, the shareholders of the
               Fund voted on September 23, 2003, to approve new management and
               sub-advisory agreements, which took effect upon closing of the
               Transaction. Neuberger is retained by Management to furnish it
               with investment recommendations and research information without
               added cost to the Fund. Several individuals who are officers
               and/or Directors of the Fund are also employees of Neuberger
               and/or Management.

               The Fund entered into a commission recapture program, which
               enables it to pay some of its operational expenses by recouping a
               portion of the commissions it pays to a broker that is not a
               related party of the Fund.

                                     NEUBERGER BERMAN APRIL 30, 2004 (UNAUDITED)

               Expenses paid through this program may include costs of
               custodial, transfer agency or accounting services. For the six
               months ended April 30, 2004, the impact of this arrangement was a
               reduction of $13,571.

               The Fund has an expense offset arrangement in connection with its
               custodian contract. The impact of this arrangement, reflected in
               the Statement of Operations under the caption Custodian fees, was
               a reduction of $1,524.

               In connection with the settlement of each Preferred Share
               auction, the Fund pays, through the auction agent, a service fee
               to each participating broker-dealer based upon the aggregate
               liquidation preference of the Preferred Shares held by the
               broker-dealer's customers. For any auction preceding a rate
               period of less than one year, the service fee is paid at the
               annual rate of 1/4 of 1%; for any auction preceding a rate period
               of one year or more, the service fee is paid at a rate agreed to
               by the Fund and the broker-dealer.

               In order to satisfy ratings agency requirements, the Fund is
               required to provide each rating agency a report on a monthly
               basis verifying that the Fund is maintaining eligible assets
               having a discounted value equal to or greater than the Preferred
               Shares Basic Maintenance Amount, which is a minimum level set by
               each rating agency as one of the conditions to maintain the AAA
               rating on the Preferred Shares. 'Discounted Value' refers to the
               fact that the rating agencies require the Fund, in performing
               this calculation, to discount portfolio securities below their
               face value, at a rate depending on their rating. The Fund pays a
               fee to State Street, as Fund sub-administrator, for the
               preparation of this report.

+    Total return based on per share net asset value reflects the effects of
     changes in net asset value on the performance of the Fund during each
     fiscal period. Total return based on per share market value assumes the
     purchase of common shares at the market price on the first day and sales of
     common shares at the market price on the last day of the period indicated.
     Dividends and distributions, if any, are assumed to be reinvested at prices
     obtained under the Fund's dividend reinvestment plan. Results represent
     past performance and do not guarantee future results. Current returns may
     be lower or higher than the performance data quoted. Total return would
     have been lower if Management had not waived a portion of the investment
     management fee. Performance data current to the most recent month-end are
     available at www.nb.com.

#    The Fund is required to calculate an expense ratio without taking into
     consideration any expense reductions related to expense offset
     arrangements.

***  After waiver of a portion of the investment management fee. Had Management
     not undertaken such action, the annualized ratios of net expenses to

     November 1, 2003, the Fund reclassified periodic interim payments on swaps
     from net investment income to net gains or losses on securities.

DIVIDEND REINVESTMENT PLAN
- --------------------------

The Bank of New York ("Plan Agent") will act as Plan Agent for shareholders who
have not elected in writing to receive dividends and distributions in cash (each
a "Participant"), will open an account for each Participant under the Dividend
Reinvestment Plan ("Plan") in the same name as their then current Shares are
registered, and will put the Plan into effect for each Participant as of the
first record date for a dividend or capital gains distribution.

Whenever the Fund declares a dividend or distribution with respect to the common
stock of the Fund ("Shares"), each Participant will receive such dividends and
distributions in additional Shares, including fractional Shares acquired by the
Plan Agent and credited to each Participant's account. If on the payment date
for a cash dividend or distribution, the net asset value is equal to or less
than the market price per Share plus estimated brokerage commissions, the Plan
Agent shall automatically receive such Shares, including fractions, for each
Participant's account. Except in the circumstances described in the next
paragraph, the number of additional Shares to be credited to each Participant's
account shall be determined by dividing the dollar amount of the dividend or
distribution payable on their Shares by the greater of the net asset value per
Share determined as of the date of purchase or 95% of the then current market
price per Share on the payment date.

Should the net asset value per Share exceed the market price per Share plus
estimated brokerage commissions on the payment date for a cash dividend or
distribution, the Plan Agent or a broker-dealer selected by the Plan Agent shall
endeavor, for a purchase period lasting until the last business day before the
next date on which the Shares trade on an "ex-dividend" basis, but in no event,
except as provided below, more than 30 days after the dividend payment date, to
apply the amount of such dividend or distribution on each Participant's Shares
(less their PRO RATA share of brokerage commissions incurred with respect to the
Plan Agent's open-market purchases in connection with the reinvestment of such
dividend or distribution) to purchase Shares on the open market for each
Participant's account. No such purchases may be made more than 30 days after the
payment date for such dividend except where temporary curtailment or suspension
of purchase is necessary to comply with applicable provisions of federal
securities laws. If, at the close of business on any day during the purchase
period the net asset value per Share equals or is less than the market price per
Share plus estimated brokerage commissions, the Plan Agent will not make any
further open-market purchases in connection with the reinvestment of such
dividend or distribution. If the Plan Agent is unable to invest the full
dividend or distribution amount through open-market purchases during the
purchase period, the Plan Agent shall request that, with respect to the
uninvested portion of such dividend or distribution amount, the Fund issue new
Shares at the close of business on the earlier of the last day of the purchase
period or the first day during the purchase period on which the net asset value
per Share equals or is less than the market price per Share, plus estimated
brokerage commissions, such Shares to be issued in accordance with the terms
specified in the third paragraph hereof. These newly issued Shares will be
valued at the then-current market price per Share at the time such Shares are to
be issued.

For purposes of making the dividend reinvestment purchase comparison under the
Plan, (a) the market price of the Shares on a particular date shall be the last
sales price on the New York Stock Exchange (or if the Shares are not listed on
the New York Stock Exchange, such other exchange on which the Shares are
principally traded) on that date, or, if there is no sale on such Exchange (or
if not so listed, in the over-the-counter market) on that date, then the mean
between the closing bid and asked quotations for such Shares on such Exchange on
such date and (b) the net asset value per Share on a particular date shall be
the net asset value per Share most recently calculated by or on behalf of the
Fund. All dividends, distributions and other payments (whether made in cash or
Shares) shall be made net of any applicable withholding tax.

Open-market purchases provided for above may be made on any securities exchange
where the Fund's Shares are traded, in the over-the-counter market or in
negotiated transactions and may be on such terms as to price, delivery and
otherwise as the Plan Agent shall determine. Each Participant's uninvested funds
held by the Plan Agent will not bear interest, and it is understood that, in any
event, the Plan Agent shall have no liability in connection with any inability
to purchase Shares within 30 days after the initial date of such purchase as
herein provided, or with the timing of any purchases effected. The Plan Agent
shall have no responsibility as to the value of the Shares acquired for each
Participant's account. For the purpose of cash investments, the Plan Agent may
commingle each Participant's funds with those of other shareholders of the Fund
for whom the Plan Agent similarly acts as agent, and the average price
(including brokerage commissions) of all Shares purchased by the Plan Agent as
Plan Agent shall be the price per Share allocable to each Participant in
connection therewith.

                                       25

The Plan Agent may hold each Participant's Shares acquired pursuant to the Plan
together with the Shares of other shareholders of the Fund acquired pursuant to
the Plan in noncertificated form in the Plan Agent's name or that of the Plan
Agent's nominee. The Plan Agent will forward to each Participant any proxy
solicitation material and will vote any Shares so held for each Participant only
in accordance with the instructions set forth on proxies returned by the
participant to the Fund.

The Plan Agent will confirm to each Participant each acquisition made for their
account as soon as practicable but not later than 60 days after the date
thereof. Although each Participant may from time to time have an undivided
fractional interest (computed to three decimal places) in a Share, no
certificates for a fractional Share will be issued. However, dividends and
distributions on fractional Shares will be credited to each Participant's
account. In the event of termination of a Participant's account under the Plan,
the Plan Agent will adjust for any such undivided fractional interest in cash at
the market value of the Shares at the time of termination, less the PRO RATA
expense of any sale required to make such an adjustment.

Any Share dividends or split Shares distributed by the Fund on Shares held by
the Plan Agent for Participants will be credited to their accounts. In the event
that the Fund makes available to its shareholders rights to purchase additional
Shares or other securities, the Shares held for each Participant under the Plan
will be added to other Shares held by the Participant in calculating the number
of rights to be issued to each Participant.

The Plan Agent's service fee for handling capital gains distributions or income
dividends will be paid by the Fund. Participants will be charged their PRO RATA
share of brokerage commissions on all open-market purchases.

Each Participant may terminate their account under the Plan by notifying the
Plan Agent in writing. Such termination will be effective immediately if the
Participant's notice is received by the Plan Agent not less than ten days prior
to any dividend or distribution record date, otherwise such termination will be
effective the first trading day after the payment date for such dividend or
distribution with respect to any subsequent dividend or distribution. The Plan
may be terminated by the Plan Agent or the Fund upon notice in writing mailed to
each Participant at least 30 days prior to any record date for the payment of
any dividend or distribution by the Fund.

These terms and conditions may be amended or supplemented by the Plan Agent or
the Fund at any time or times but, except when necessary or appropriate to
comply with applicable law or the rules or policies of the Securities and
Exchange Commission or any other regulatory authority, only by mailing to each
Participant appropriate written notice at least 30 days prior to the effective
date thereof. The amendment or supplement shall be deemed to be accepted by each
Participant unless, prior to the effective date thereof, the Plan Agent receives
written notice of the termination of their account under the Plan. Any such
amendment may include an appointment by the Plan Agent in its place and stead of
a successor Plan Agent under these terms and conditions, with full power and
authority to perform all or any of the acts to be performed by the Plan Agent
under these terms and conditions. Upon any such appointment of any Plan Agent
for the purpose of receiving dividends and distributions, the Fund will be
authorized to pay to such successor Plan Agent, for each Participant's account,
all dividends and distributions payable on Shares held in their name or under
the Plan for retention or application by such successor Plan Agent as provided
in these terms and conditions.

The Plan Agent shall at all times act in good faith and agrees to use its best
efforts within reasonable limits to ensure the accuracy of all services
performed under this Agreement and to comply with applicable law, but assumes no
responsibility and shall not be liable for loss or damage due to errors unless
such error is caused by the Plan Agent's negligence, bad faith, or willful
misconduct or that of its employees.

These terms and conditions shall be governed by the laws of the State of
Maryland.
