N-CSR EXHIBIT FOR ITEM 10(a): CODE OF ETHICS


               LEHMAN BROTHERS/FIRST TRUST INCOME OPPORTUNITY FUND

                   CODE OF ETHICS FOR PRINCIPAL EXECUTIVE AND
                            SENIOR FINANCIAL OFFICERS

I.      COVERED OFFICERS/PURPOSE OF THE CODE

        The code of ethics (this "Code") for Lehman Brothers/First Trust Income
Opportunity Fund (the "Fund") applies to the Fund's principal executive officer
and principal financial and accounting officer (the "Covered Officers," each of
whom is set forth in Exhibit A) for the purpose of promoting:

  -  honest and ethical conduct, including the ethical handling of actual or
     apparent conflicts of interest between personal and professional
     relationships;

  -  full, fair, accurate, timely and understandable disclosure in reports and
     documents that the Fund files with, or submits to, the Securities and
     Exchange Commission ("SEC") and in other public communications made by the
     Fund;

  -  compliance with applicable laws and governmental rules and regulations;

  -  the prompt internal reporting of violations of the Code to an appropriate
     person or persons identified in the Code; and

  -  accountability for adherence to the Code.

     Each Covered Officer should adhere to a high standard of business ethics
and should be sensitive to situations that may give rise to actual as well as
apparent conflicts of interest.

II.     Covered Officers Should Handle Ethically Actual and Apparent Conflicts
        of Interest

        OVERVIEW. A "conflict of interest" occurs when a Covered Officer's
private interests interfere with the interests of, or his service to, the Fund.
For example, a conflict of interest would arise if a Covered Officer, or a
member of his family, receives improper personal benefits as a result of his
position with the Fund.

        Certain conflicts of interest arise out of the relationships between
Covered Officers and the Fund and already are subject to conflict of interest
provisions in the Investment Company Act of 1940, as amended ("Investment
Company Act") and the Investment Advisers Act of 1940, as amended ("Investment
Advisers Act"). For example, Covered Officers may not individually engage in
certain transactions (such as the purchase or sale of securities or other
property) with the Fund because of their status as "affiliated persons" of the
Fund. The compliance programs and procedures of the Fund or the Fund's
investment adviser or sub-adviser (the "investment adviser") are designed to
prevent, or identify and correct, violations of these provisions. This Code does
not, and is not intended to, repeat or replace these programs and procedures,
and such conflicts fall outside of the parameters of this Code. Although
typically not presenting an opportunity for improper personal benefit, conflicts
may arise from, or as a result of, the contractual relationship between the Fund
and the investment adviser or a third party service provider of which a Covered
Officer is also an officer or employee. As a result, this Code recognizes that
the Covered Officers will, in the normal course of their duties (whether
formally for the Fund and/or for the investment adviser or a third party service
provider) be involved in establishing policies and implementing decisions that
will have different effects on the investment adviser or a third party service
provider and the Fund. The participation of the Covered Officers in such
activities is inherent in the contractual relationship between the Fund and the
investment adviser or a third party service provider and is consistent with the
performance by the Covered Officers of their duties as officers of the Fund. The
foregoing activities, if performed in conformity with the provisions of the
Investment Company Act and the Investment Advisers Act, will be deemed to have
been handled ethically.

                                        5
<Page>

        Other conflicts of interest are covered by the Code, even if such
conflicts of interest are not subject to provisions in the Investment Company
Act and the Investment Advisers Act. The overarching principle with respect to
all conflicts of interest covered by this Code is that the personal interest of
a Covered Officer should not be placed improperly before the interest of the
Fund.

     Each Covered Officer must:

     -  not use personal influence or personal relationships improperly to
        influence investment decisions or financial reporting by the Fund
        whereby the Covered Officer would benefit personally to the detriment of
        the Fund;

     -  not cause the Fund to take action, or fail to take action, for the
        individual personal benefit of the Covered Officer rather than the
        benefit of the Fund;

     -  report at least annually any affiliations or other relationships that
        could potentially present a conflict of interest with the Fund.

III.    DISCLOSURE AND COMPLIANCE

   -    Each Covered Officer shall become familiar with the disclosure
        requirements generally applicable to the Fund;

   -    each Covered Officer shall not knowingly misrepresent, or cause others
        to misrepresent, facts about the Fund to others, whether within or
        outside the Fund, including to the Fund's management, and auditors, and
        to governmental regulators and self-regulatory organizations;

   -    each Covered Officer may, to the extent appropriate within the Covered
        Officer's area of responsibility and to the extent deemed necessary in
        the sole discretion of the Covered Officer, consult with other officers
        and employees of the Fund and the investment adviser with the goal of
        promoting full, fair, accurate, timely and understandable disclosure in
        the reports and documents the Fund files with, or submits to, the SEC
        and in other public communications made by the Fund; and

   -    each Covered Officer should seek to promote the Fund's compliance with
        the standards and restrictions imposed by applicable laws, rules and
        regulations.

IV. REPORTING AND ACCOUNTABILITY

   Each Covered Officer must:

- -       upon adoption of the Code (or thereafter as applicable, upon becoming a
     Covered Officer), affirm in writing to Chamaine Williams or such other
     person designated by the Secretary of the Fund (the "Compliance Officer")
     that the Covered Officer has received, read and understands this Code;

- -       annually thereafter affirm to the Compliance Officer that the Covered
     Officer has complied with the requirements of this Code;

- -       not retaliate against any other Covered Officer or any employee of the
     Fund or its affiliated persons for reports of potential violations of this
     Code that are made in good faith; and

- -       notify the Compliance Officer promptly if the Covered Officer knows of
     any violation of this Code. Failure to do so is itself a violation of this
     Code.

        The Compliance Officer is responsible for applying this Code to specific
situations in which questions are presented under it and has the authority to
interpret this Code in any particular situation. The Compliance Officer is
authorized to consult, as appropriate, with counsel to the Fund, and is
encouraged to do so. However, any approvals or

                                        6
<Page>

waivers(1) must be considered by the trustees of the Fund who are not
"interested persons," as defined by Section 2(a)(19) of the Investment Company
Act, of the Fund (the "Independent Trustees").

        The Fund will follow these procedures in investigating and enforcing
this Code:

     -  The Compliance Officer will endeavor to take all appropriate action to
        investigate any reported potential violations reported to him;

     -  if, after such investigation, the Compliance Officer believes that no
        violation has occurred, the Compliance Officer is not required to take
        any further action;

     -  any matter that the  Compliance  Officer  believes is a  violation  will
        be reported to the  Independent Trustees;

     -  if the Independent Trustees concur that a violation has occurred, the
        Compliance Officer will inform and make a recommendation to the Fund's
        board of trustees (the "Board"), which will consider appropriate action,
        which may include a review of, and appropriate modifications to,
        applicable Fund policies and procedures; notification to appropriate
        personnel of the investment adviser or other relevant service provider;
        or a recommendation to dismiss the Covered Officer; and

     -  any changes to or waivers of this Code will, to the extent required, be
        disclosed as provided by SEC rules.

V.      OTHER POLICIES AND PROCEDURES

   This Code shall be the sole code of ethics adopted by the Fund for purposes
of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms
applicable to registered investment companies thereunder. Insofar as other
policies or procedures of the Fund, investment adviser, principal underwriter or
service providers govern or purport to govern the behavior or activities of the
Covered Officers who are subject to this Code, they are superseded by this Code
to the extent that they overlap or conflict with the provisions of this Code.
The Fund's and the investment adviser's and the principal underwriter's codes of
ethics under Rule 17j-1 under the Investment Company Act are separate
requirements applying to the Covered Officers and others, and are not part of
this Code.

VI.     AMENDMENTS

   Amendments to this Code may be made from time to time, as deemed appropriate
by the Compliance Officer. The Board shall be informed of any such amendment to
the extent deemed material by the Compliance Officer.

VII.    CONFIDENTIALITY

   All reports and records relating to the Fund prepared or maintained pursuant
to this Code will be considered confidential and shall be maintained and
protected accordingly. Except as otherwise required by law or this Code, such
matters shall not be disclosed to anyone other than the investment adviser,
Board, and counsel to the Fund.

VIII.   INTERNAL USE

   The Code is intended solely for the internal use by the Fund and does
not constitute an admission, by or on behalf of the Fund, as to any fact,
circumstance, or legal conclusion.


- ----------
(1) For this purpose, the term "waiver" includes the approval by the Fund of a
material departure from a provision of this Code or the Fund's failure to take
action within a reasonable period of time regarding a material departure from a
provision of this Code that has been made known to the Fund's management.

N-CSR EXHIBIT FOR ITEM 10(b): REGISTRANT'S PROXY VOTING PROCEDURES AND
GUIDELINES

LINCOLN CAPITAL FIXED INCOME MANAGEMENT COMPANY, LLC

                              PROXY VOTING POLICIES

Lincoln Capital Fixed Income Management Company, LLC (Lincoln Capital) is aware
and compliant with SEC Rule 206(4)-6 regarding proxy voting and disclosure and
Rule 204-2 pertaining to books and records. Therefore, Lincoln Capital shall
vote corporate governance proposals in a manner that promotes clear
responsibility of management and boards to the long run interests of
shareholders. Lincoln Capital shall be diligent, independent and consider the
best interest of our clients in arriving at proxy voting decisions.

Upon a client's request, Lincoln Capital will disclose how the client's proxies
were voted. Clients can send their requests via e-mail to Csedlak@Lincap.com.

                             PROXY VOTING PROCEDURES

Ann Benjamin, a Managing Director, or a designee, is responsible for Lincoln
Capital's proxy votes and guidelines for high yield products. The Security
Control unit within the Portfolio Management Information Department has
administrative responsibility.

Guidelines have been established to apply to the most frequently appearing proxy
proposals. Proxy proposals for shares in closed-end funds are excepted from the
guidelines, and voting decisions relating to such proposals will be determined
on a case-by-case basis. Where specific guidelines don't apply, the general
principles of the Proxy Voting Policies are used. Specific fact situations might
warrant departure from the guidelines. Proxies are voted after review of
relevant materials (annual report, SEC filings -10K, and votes registered from
the prior year) in accordance with these guidelines. The voting rights of
securities that are on loan are determined at the time of signing the loan
agreement between our clients and their custodian banks; usually the securities
on loan do not allow Lincoln Capital the voting rights.

Administratively, Lincoln Capital utilizes paper ballots. Paper ballots are
received via the United States Postal System and holdings for all clients as of
record date are obtained from the accounting system (Portia). The ballots'
shares and Lincoln Capital's holdings are verified. If there are discrepancies
between the ballot shares and Lincoln Capital's holdings, the custodian is
contacted for resolution. Proxies are voted by choosing the appropriate vote
selection and the signing of the paper ballots. The signed proxies are mailed in
the provided pre-addressed envelope.

In rare instances where ballot shares have not been received from all custodians
within two weeks of the meeting date, Lincoln Capital contacts the custodian.
The custodian will follow up with a faxed copy of the paper ballot. If a copy of
the ballot is faxed, Lincoln Capital returns (via fax or by mail) the proxy with
voting instructions to the custodian.

After all proxies are voted, the Portfolio Management Information Department of
Lincoln Capital keeps a copy of the signed ballot as record of the security,
meeting date, proposals, and how we voted for each client. Records are
maintained in the Portfolio Management Information Department of Lincoln Capital
office for five years; after that time the records can be moved to an off-site
facility.

The guidelines are designed to eliminate the influence of any conflicts of
interest on Lincoln Capital's proxy voting decisions. Although Lincoln Capital
does not foresee any material conflicts of interest arising, in the event a
material conflict of interest does arise, the facts and circumstances of the
conflict would be discussed with Lori Loftus, the Compliance Manager, prior to
voting. Lori Loftus and Ann Benjamin will decide if the conflict can be resolved
or avoided by applying the guidelines. If the conflict cannot be resolved or
avoided by applying the guidelines, Lincoln Capital may rely on the advice of an
independent third party to determine how to vote the proxy.

                                                           shareholders. However, if directors seriously breech their fiduciary

Blank check preferred               Against                These proposals are for the authorization of shares for which voting
                                                           rights are not established in advance. Instead, voting rights are
                                                           established at the discretion of the board of directors when the shares
                                                           are issued. This gives the board the ability to place a block of stock
                                                           with an investor sympathetic to management, thereby foiling a takeover
                                                           bid without a shareholder vote. This proposal is a transfer of authority
                                                           from shareholders to the board, and a possible entrenchment device.

Stockholder provision               Against                These proposals introduce the concept that the board may consider the

                                                           takeover offers. This concept is inconsistent with public ownership of

SOCIAL ISSUES

Most social issues are handled on a case-by-case basis. Unique social,
environmental, and political issues are decided on the merits of the specific
