CHAIRMAN'S LETTER

DEAR SHAREHOLDER,

I am pleased to present to you this annual report for the Neuberger Berman
Income Opportunity Fund Inc., for the period ending October 31, 2004. The report
includes portfolio commentary, a listing of the Fund's investments, and its
audited 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 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 that our conservative investing philosophy and disciplined investment
process will benefit shareholders by providing attractive 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 one-year period ending October 31, 2004, on a Net Asset Value (NAV)
     basis, the Neuberger Berman Income Opportunity Fund Inc. (AMEX:NOX)
     provided a 23.67% return.

     Although the Fund has only been open since June 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 another portion in 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, due to a strong REIT market in 2003. The Asset Allocation
     Committee, which consists of Neuberger Berman Management Inc.'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 October 31, 2004,
     the Fund held 38.8% of its investments in REIT common stocks, 13.2% in REIT
     preferred stocks, 45.8% in bonds, and 2.2% in cash.

     REAL ESTATE INVESTMENT TRUST HOLDINGS

     Over the past 12 months, the REIT market overall was very strong, primarily
     due to improving economic conditions, a benign interest rate environment,
     and stronger real estate fundamentals. As the economy gained traction,
     demand and occupancy levels for commercial real estate also improved. In
     addition, investors continued to emphasize companies with visible earnings,
     which benefited the REIT market.

     Within the REIT industry, regional malls, shopping centers, and industrial
     properties did particularly well. Retailers also performed well, as they
     continued to expand, causing occupancy and rent levels to increase. Healthy
     consumer spending also contributed to retailers' strong performance.
     Industrial REITs generated good returns primarily due to core improvements
     in parts of the U.S. economy. Within the portfolio, retail and industrial
     REITs contributed nicely to overall performance.

     On the other hand, REITs that own office properties performed less well.
     Office properties underperformed due to concerns about oversupply and
     modest expansion plans. Apartment sector underperformance resulted from the
     low interest rate environment, encouraging first time home buyers to become
     more active.

     As we look out to 2005, we believe we will see continued improvement in the
     U.S. economy and improving fundamentals for most types of real estate,
     albeit with expectations for higher interest rates. Our general outlook for
     REITs remains favorable and we believe that demand for REITs has the
     potential to remain robust.

     HIGH-YIELD SECURITIES HOLDINGS

     The fixed-income market generated strong returns during the period,
     particularly within the high-yield sector. High-yield "spreads," which
     represent the coupon differential between high-yield bonds and comparable
     five- and ten-year Treasury securities, narrowed steadily throughout the
     reporting period. We believe that narrowing credit spreads reflect improved
     economic conditions, as well as stronger corporate balance sheets and
     financial conditions. Over the last several years, improving cost controls
     have helped to drive substantial margin improvements for many companies.
     Issuers of high-yield debt have also taken advantage of low interest rates
     to refinance existing debt and generally reduce their financing costs.

     Spreads are not yet at historically "tight" levels, but considering they
     have narrowed substantially, we believe that it is especially important for
     the Fund

                                        2

                                               NEUBERGER BERMAN OCTOBER 31, 2004

     to stick to its discipline of buying the higher quality securities among
     the high yield market. Our conservative positioning may hold back the
     Fund's performance when lower-quality high-yield bonds are performing well,
     but over time, our approach has produced a track record of steady,
     consistent returns.

     A variety of factors have contributed to spread tightening and credit
     improvement across several industries. During the period, a weakening U.S.
     dollar benefited the industrial sector of the high-yield market. A more
     cautious approach to deregulation has allowed utility companies to repair
     their balance sheets, which in turn has resulted in credit quality
     upgrades. Energy securities have benefited from a tight supply/demand
     dynamic based in large part on economic strength globally and political
     uncertainty in a variety of oil-producing regions.

     Against a backdrop of narrow credit spreads and a weak U.S. dollar, we
     believe that a conservative approach is the best strategy going forward.
     Therefore, we are maintaining a relatively short duration and maturity
     stance and are continuing to pare back the number of holdings in the
     portfolio. We also remain focused on upgrading the portfolio's credit
     quality.

     Our outlook for the high-yield market remains optimistic. Investors appear
     comforted by recent economic releases that suggest a rebound in economic
     activity. At the same time, inflation remains subdued, despite still-high
     energy prices. We believe that these factors foster expectations for a
     moderate and sustainable level of economic growth -- a notion underscored
     by the Federal Reserve Board's four interest rate increases since June, and
     its announced proclivity toward raising rates at a "measured" pace going
     forward.

     We believe that the return potential for the high-yield market should
     remain positive. However, returns are likely to result from income for the
     rest of 2004. Interest rates may have bottomed for this cycle, but the term
     structure of rates remains low by historic standards and investor appetite
     for higher-yielding products continues to be robust.

     Our investment orientation will remain toward keeping duration relatively
     short. This part of the yield curve still provides compelling income, but
     historically has minimized risks related to rising interest rates. We also
     intend to maintain our focus on credit selection and keep the high-yield
     bond portion of the portfolio well diversified across industries.

     Sincerely,

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

Closed-end funds, unlike open-end funds, are not continually offered. There is
an initial public offering and once issued, common shares of closed-end funds
are sold in the open market through a stock exchange.

NOTES TO SCHEDULE OF INVESTMENTS

     +    Investments in equity securities by Neuberger Berman Income
          Opportunity Fund Inc. (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. 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 and 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 noon, 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.
          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 October 31, 2004, the cost of investments for U.S. Federal income
          tax purposes was $428,321,000. Gross unrealized appreciation of
          investments was $40,453,000 and gross unrealized depreciation of
          investments was $993,000, resulting in net unrealized appreciation of
          $39,460,000, based on cost for U.S. Federal income tax purposes.

          also managed by Neuberger Berman Management Inc. (see Notes A and E of
          Notes to Financial Statements) and may be considered an affiliate
          since it has the same officers, Board members, and investment manager
          as the Fund and because, at times, the Fund may own 5% or more of the
          outstanding voting securities of Institutional Cash.

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 "1940 Act"). 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
       (the "Board") 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 U.S. generally
       accepted accounting principles 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  INCOME TAX INFORMATION: It is the policy of the Fund to continue to
       qualify as a regulated investment company by complying with the
       requirements of Subchapter M of the Internal Revenue Code applicable to
       regulated investment companies and to distribute substantially all of its
       earnings to its shareholders. Therefore, no Federal income or excise tax
       provision is required.

       Income dividends and capital gain distributions are determined in
       accordance with income tax regulations, which may differ from generally
       accepted accounting principles. These differences are primarily due to
       differing treatments of income and gains on various investment securities
       held by the Fund, timing differences and differing characterization of
       distributions made by the Fund as a whole.

       As determined on October 31, 2004, permanent differences resulting
       primarily from different book and tax accounting for distributions in
       excess of earnings, amortization of bond premium, and income recognized
       on interest rate swaps were reclassified at year end. These
       reclassifications had no effect on net income, net assets or net assets
       per share of the Fund.

                                       17

       The tax character of distributions paid during the periods ended October
       31, 2004 and October 31, 2003 were as follows:

<Table>

</Table>

       As of October 31, 2004, 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
                                                                        
                $  4,797,620     $  1,095,747     $  38,658,796           $   --    $  44,552,163
</Table>

       The difference between book basis and tax basis distributable earnings
       are primarily due to timing differences of dividend payments, wash sales,
       amortization of bond premium, and income recognized on interest rate
       swaps.

    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 to the extent of any available 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.

       The Fund invests a significant portion of its assets in securities issued
       by real estate companies, including real estate investment trusts
       ("REITs"). The distributions received from REITs held by the Fund are
       generally comprised of investment income, long-term capital gains, and
       return of REIT capital but the REITs do not report this information to
       the Fund until the Following calendar year. At October 31, 2004, the Fund
       estimated these amounts within the Statement of Operations since the
       information is not available from the REITs until after the Fund's fiscal
       year end. The character of distributions paid to shareholders, as
       disclosed within the Statement of Changes, is based on these estimates.
       All estimates are based upon REIT information sources available to the
       Fund together with actual IRS Form 1099s received to date. After calendar
       year-end, REITs 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. After all applicable REITs have informed the Fund of
       the actual breakdown of distributions paid to the Fund during its fiscal
       year, the Fund adjusts to actual, estimates previously recorded. 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 IRS Form 1099.

                                       18

                                               NEUBERGER BERMAN OCTOBER 31, 2004

       On September 29, 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 the close of the reporting period, on
       November 30, 2004 and December 31, 2004, to shareholders of record on
       November 12, 2004 and December 15, 2004, respectively, with ex-dividend
       dates of November 10, 2004 and December 13, 2004, respectively.

    6  EXPENSE ALLOCATION: Certain expenses 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 year ended
       October 31, 2004, dividend rates ranged from 1.07% to 1.95% for Series A
       and 1.05% to 1.96% for Series B Auction Preferred Shares. The Fund
       declared dividends to preferred shareholders for the period November 1,
       2004 to November 30, 2004 of $103,043 and $103,416 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 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 or the Fund's charter. 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. Under the terms of the interest rate swap agreements,
       the Fund agrees to pay the swap counter party a fixed-rate payment

                                       19
<Page>

       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
       fixed-rate and variable-rate payment flows are netted against each other,
       with the difference being paid by one party to the other on a monthly
       basis. The Fund segregates 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.

       Prior to November 1, 2003, 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.
       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, 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. As a
       result of the SEC staff guidance, the Fund recorded an adjustment to
       reflect the reclassification of such amounts. The adjustment 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 $1,960,648, increased net realized losses by
       $1,929,295 and decreased unrealized appreciation (depreciation) in value

       (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
       Board, monitors the creditworthiness of the parties to whom the Fund
       makes security loans. The

                                       20
<Page>

       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 guaranteed a certain amount
       of revenue to the Fund under the Agreement, and received a portion of any
       revenue earned in excess of the guaranteed amount as a lending agency
       fee. For the year ended October 31, 2004, the Fund paid Neuberger $11,468
       under the Agreement.

       The Agreement has been renewed and approved by the Board as of July 1,
       2004 with substantially the same terms. Under this current Agreement,
       Neuberger guarantees a certain amount of revenue to the Fund and receives
       any revenue earned in excess of the guaranteed amount as a lending agency
       fee.

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

   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 year ended October 31, 2004, management
       fees waived on the Cash Fund amounted to $1,606. For the year ended
       October 31, 2004, income earned on this investment amounted to $13,612
       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 $312,741. 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.

                                       21
<Page>

       Additionally, offering costs of $292,294 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 may 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 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.

   14  INDEMNIFICATIONS: Like many other companies, the Fund's organizational
       documents provide that its officers and directors are indemnified against
       certain liabilities arising out of the performance of their duties to the
       Fund. In addition, both in some of its principal service contracts and in
       the normal course of its business, the Fund enters into contracts that
       provide indemnifications to other parties for certain types of losses or
       liabilities. The Fund's maximum exposure under these arrangements is
       unknown as this could involve future claims against the Fund.

       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:

                                               NEUBERGER BERMAN OCTOBER 31, 2004

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

       For the year ended October 31, 2004, such waived fees amounted to
       $1,008,005.

       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. 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.
       Expenses paid through this program may include costs of custodial,
       transfer agency or accounting services. For the year ended October 31,
       2004, the impact of this arrangement was a reduction of $14,661.

       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 $1,644.

       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 rating agencies' 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.

       NOTE C--SECURITIES TRANSACTIONS:

       During the year ended October 31, 2004, there were purchase and sale
       transactions (excluding short-term securities and interest rate swap
       contracts) of $306,605,000 and $290,239,000, respectively.

                                       23

       During the year ended October 31, 2004, brokerage commissions on
       securities transactions amounted to $58,688, of which Neuberger received
       $0, Lehman received $13,101, and other brokers received $45,587.

+     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.

Neuberger Berman Income Opportunity Fund Inc.

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Neuberger Berman Income Opportunity Fund Inc.,
(the "Fund") as of October 31, 2004, and the related statement of operations for
the year ended October 31, 2004, statements of changes in net assets for the
year in the ended October 31, 2004 and for the period from July 2, 2003
(commencement of operations) to October 31, 2004 and financial highlights for
the periods indicated therein. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial

includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements and financial highlights. Our procedures
included confirmation of securities owned as of October 31, 2004, by
correspondence with the custodian and brokers or other appropriate auditing
procedures where replies from brokers were not received. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Neuberger Berman Income Opportunity Fund Inc., at October 31, 2004, the results
of its operations for the year ended October 31, 2004, changes in its net assets
for the year ended October 31, 2004 and the period from July 2, 2003

for the periods indicated herein, in conformity with U.S. generally accepted
accounting principles.

DIVIDEND REINVESTMENT PLAN (UNAUDITED)

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.

                                               NEUBERGER BERMAN OCTOBER 31, 2004

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.

assurance  and  related  services  by E&Y that  are  reasonably  related  to the

reporting of the Registrant were $0 and $0 for 2004 and 2003, respectively.

(c) Tax Fees
    --------

The aggregate fees billed to the Registrant in each of the last two fiscal years

(e) Audit Committee's Pre-Approval Policies and Procedures
    ------------------------------------------------------

ITEM 6. SCHEDULE OF INVESTMENTS

The  complete  schedule  of  investments  for each  series is  disclosed  in the
Registrant's Annual Report, which is included as Item 1 of this Form N-CSR.

ITEM 7.  DISCLOSURE  OF PROXY VOTING  POLICIES  AND  PROCEDURES  FOR  CLOSED-END
MANAGEMENT INVESTMENT COMPANIES

The Board has  delegated  to  Neuberger  Berman,  LLC  ("Neuberger  Berman") the
responsibility  to vote  proxies  related to the  securities  held in the Fund's
portfolios.  Under this authority,  Neuberger Berman is required by the Board to
vote proxies  related to portfolio  securities in the best interests of the Fund
and its  stockholders.  The Board  permits  Neuberger  Berman to contract with a
third party to obtain proxy voting and related services,  including  research of
current issues.

Neuberger  Berman has  implemented  written Proxy Voting Policies and Procedures
("Proxy  Voting  Policy") that are designed to reasonably  ensure that Neuberger
Berman votes proxies  prudently and in the best interest of its advisory clients
for whom Neuberger  Berman has voting  authority,  including the Fund. The Proxy
Voting Policy also describes how Neuberger  Berman  addresses any conflicts that
may arise  between its  interests and those of its clients with respect to proxy
voting.

Neuberger  Berman's Proxy Committee is responsible for developing,  authorizing,
implementing  and updating the Proxy Voting Policy,  overseeing the proxy voting
process and engaging  and  overseeing  any  independent  third-party  vendors as



voting  delegate to review,  monitor and/or vote proxies.  In order to apply the
Proxy Voting  Policy noted above in a timely and  consistent  manner,  Neuberger
Berman utilizes Institutional  Shareholder Services Inc. ("ISS") to vote proxies
in accordance with Neuberger Berman's voting guidelines.

Neuberger Berman's guidelines adopt the voting recommendations of ISS. Neuberger
Berman retains final  authority and fiduciary  responsibility  for proxy voting.
Neuberger  Berman  believes that this process is reasonably  designed to address
material  conflicts of interest  that may arise between  Neuberger  Berman and a
client as to how proxies are voted.

In the event that an investment  professional at Neuberger  Berman believes that
it is in the best  interests  of a client or clients to vote proxies in a manner
inconsistent  with  Neuberger  Berman's  proxy voting  guidelines or in a manner
inconsistent  with  ISS   recommendations,   the  Proxy  Committee  will  review
information submitted by the investment  professional to determine that there is
no material  conflict of interest  between  Neuberger Berman and the client with
respect to the voting of the proxy in that manner.

If the Proxy  Committee  determines that the voting of a proxy as recommended by
the investment  professional  presents a material  conflict of interest  between
Neuberger  Berman and the client or  clients  with  respect to the voting of the
proxy, the Proxy Committee shall: (i) take no further action,  in which case ISS
shall vote such proxy in accordance  with the proxy voting  guidelines or as ISS
recommends;  (ii)  disclose  such  conflict  to the client or clients and obtain
written  direction  from the client as to how to vote the proxy;  (iii)  suggest
that the client or clients  engage  another  party to determine  how to vote the
proxy; or (iv) engage another  independent  third party to determine how to vote
the proxy.

ITEM 8.  PURCHASES OF EQUITY  SECURITIES  BY  CLOSED-END  MANAGEMENT  INVESTMENT
COMPANY AND AFFILIATED PURCHASERS

No reportable purchases for the period covered by this report.

ITEM 9.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

There were no changes to the  procedures  by which  shareholders  may  recommend
nominees to the Board.

ITEM 10. CONTROLS AND PROCEDURES

(a)      Based on an evaluation of the  disclosure  controls and  procedures (as
         defined in rule 30a-3(c) under the  Investment  Company Act of 1940, as
         amended  (the "Act")) as of a date within 90 days of the filing date of
         this document,  the Chief Executive Officer and Treasurer and Principal
         Financial and Accounting  Officer of the Registrant have concluded that
         such  disclosure  controls and procedures are  effectively  designed to
         ensure that  information  required to be disclosed by the Registrant is
         accumulated and  communicated to the  Registrant's  management to allow
         timely decisions regarding required disclosure.



(b)      There were no significant changes in the Registrant's internal controls
         over  financial  reporting (as defined in rule 30a-3(d)  under the Act)
         that occurred during the  Registrant's  last fiscal half-year that have
         materially affected, or are reasonably likely to materially affect, the
         Registrant's internal control over financial reporting.

ITEM 11. EXHIBITS

         Registrant's Form N-CSR,  Investment  Company Act file number 811-21334

(a)(2)   The certifications required by Rule 30a-2(a) of the Act and Section 302
         of the Sarbanes-Oxley Act of 2002  ("Sarbanes-Oxley  Act") are attached

(b)      The certification  required by Rule 30a-2(b) of the Act and Section 906

are not deemed "filed" for purposes of Section 18 of the Securities Exchange Act
of 1934 ("Exchange Act"), or otherwise subject to the liability of that section.
Such  certifications will not be deemed to be incorporated by reference into any
filing  under the  Securities  Act of 1933 or the  Exchange  Act,  except to the
extent that the Registrant specifically incorporates them by reference.
