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


(+)  Investments in debt securities by Lehman Brothers First Trust
     Income Opportunity Fund (the "Fund") are valued daily by obtaining
     valuations from independent pricing services based on readily available
     bid quotations, or if quotations are not available, by methods which
     include considerations such as: yields or prices of securities of
     comparable quality, coupon, maturity and type; indications as to values
     from dealers; and general market conditions. If a valuation is not
     available from an independent pricing service, the Fund seeks to obtain
     quotations from principal market makers. If such quotations are not
     readily available, securities are valued using methods the Board of
     Trustees of the Fund (the "Board") has approved on the belief that they
     reflect 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. 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 is next
     quoted or next trades.


     The Fund adopted Financial Accounting Standards Board ("FASB") Statement
     of Financial Accounting Standards No. 157, Fair Value Measurements ("FAS
     157"), effective January 1, 2008. In accordance with FAS 157, "fair
     value" is defined as the price that a Fund would receive upon selling an
     investment in an orderly transaction to an independent buyer in the
     principal or most advantageous market for the investment. Various inputs
     are used in determining the value of the Fund's investments.  FAS 157
     established a three-tier hierarchy of inputs to establish a
     classification of fair value measurements for disclosure purposes. The
     three-tier hierarchy of inputs is summarized in the three broad Levels
     listed below.

     o  Level 1 - quoted prices in active markets for identical investments
     o  Level 2 - other significant observable inputs (including quoted prices
        for similar investments, interest rates, prepayment speeds, credit risk,
        etc.)
     o  Level 3 - significant unobservable inputs (including the Fund's own
        assumptions in determining the fair value of investments)

     The inputs or methodology used for valuing an investment are not
     necessarily an indication of the risk associated with investing in those
     securities.

     The following is a summary of the inputs used to value the Fund's
     investments as of September 30, 2008:

     Following is a reconciliation between the beginning and ending balances
     of investments in which significant unobservable inputs (Level 3) were
     used in determining value:

from investments still held as of 09/30/08                        $-


(##) At September 30, 2008, the cost of investments for U.S. federal income
     tax purposes was $252,285,640. Gross unrealized appreciation of
     investments was $114,766 and gross unrealized depreciation of
     investments was $27,562,216, resulting in net unrealized depreciation of
     $27,447,450, based on cost for U.S. federal income tax purposes.

(@)  Neuberger Berman Prime Money Fund ("Prime Money") is also managed by
     Neuberger Berman Management LLC. 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 Prime Money.

(n)  Restricted security subject to restrictions on resale
     under federal securities laws.  These securities may be resold in
     transactions exempt from registration, normally to qualified

        over  financial  reporting (as defined in rule  30a-3(d)  under the 1940
