                         EFFECTIVE DATE: _________, 2005

I.       COVERED OFFICERS/PURPOSE OF THE CODE

     This Code of Ethics (the "Code") for the investment companies within the
     HATTERAS MASTER FUND, L.P., HATTERAS MULTI-STRATEGY FUND I, L.P. and
     HATTERAS MULTI-STRATEGY TEI FUND, L.P. (collectively the "Funds" and each,
     a "Fund") applies to the Funds' Principal Executive Officer, Principal
     Financial Officer, and Principal Accounting Officer, if any (the "Covered
     Officers") for the purpose of promoting:

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

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

       o  compliance   with   applicable   laws  and   governmental   rules  and
          regulations;

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

       o  accountability for adherence to the Code.

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

II.      ADMINISTRATION OF THE CODE

           ADMINISTRATION. The administration of the Code shall be supervised by
     the Funds' Chief Compliance Officer.

           Any waivers sought by a Covered Officer must be approved by each
     Audit Committee of the Funds (collectively, the "Audit Committee").

III.     MANAGING CONFLICTS OF INTEREST

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


           Certain conflicts of interest arise out of the relationships between
     Covered Officers and a Fund and already are subject to conflict of interest
     provisions in the Investment Company Act of 1940, as amended (the "Company
     Act"), and the Investment Advisers Act of 1940, as amended (the "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 a Fund because of their status as "affiliated persons" of the Fund. A
     Fund's and its investment adviser's compliance programs and procedures are
     designed to prevent, or identify and correct, violations of those
     provisions. This Code does not, and is not intended to, repeat or replace
     those 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 a Fund and its investment adviser,
     administrator, principal underwriter, pricing and bookkeeping agent and/or
     transfer agent (each, a "Service Provider") of which the Covered Officers
     are also officers or employees. As a result, this Code recognizes that the
     Covered Officers will, in the normal course of their duties (whether
     formally for a Fund or for a Service Provider, or for both), be involved in
     establishing policies and implementing decisions that will have different
     effects on the Service Provider and a Fund. The participation of the
     Covered Officers in such activities is inherent in the contractual
     relationship between the Fund and the Service Provider and is consistent
     with the performance by the Covered Officers of their duties as officers of
     a Fund. In addition, it is recognized by the Board that the Covered
     Officers may also be officers or employees of one or more other investment
     companies covered by this or other codes.

           Other conflicts of interest are covered by the Code, even if such
     conflicts of interest are not subject to provisions of the Company Act and
     the Advisers Act. The following list provides examples of conflicts of
     interest under the Code, but Covered Officers should keep in mind that
     these examples are not exhaustive. The overarching principle is that the
     personal interest of a Covered Officer should not be placed improperly
     before the interest of a Fund.

           Each Covered Officer must:

                o   not use personal influence or personal relationships
                    improperly to influence investment decisions or financial
                    reporting by a Fund whereby the Covered Officer or an
                    immediate family member would benefit personally to the
                    detriment of a Fund;

                o   not cause a Fund to take action, or fail to take action, for
                    the individual personal benefit of the Covered Officer or an
                    immediate family member rather than the benefit of the
                    Fund;(1)

- ---------------------------------
(1) For purposes of this Code, personal trading activity of the Covered Officers
shall be monitored in accordance with the Funds Code of Ethics. Each Covered
Officer shall be considered an "Access Person" under such Code. The term
"immediate family" shall have the same meaning as provided in such Code.



               o    not  use   material   non-public   knowledge   of  portfolio
                    transactions  made or contemplated  for the Company to trade
                    personally   or  cause   others  to  trade   personally   in
                    contemplation of the market effect of such transactions; and

               o    report at least annually his or her  affiliations  and other
                    relationships  on each Fund's annual  Directors and Officers
                    Questionnaire.

           There are some conflict of interest situations that must be approved
     by the Chief Compliance Officer, after consultation with the Chief Legal
     Officer. Those situations include, but are not limited to:

               o    serve as  director  on the board of any  public  or  private
                    company;

               o    the  receipt  during  any  12-month  period  of any gifts in
                    excess of $100 in the aggregate from a third party that does
                    or seeks to do business with the Funds; and

               o    the receipt of any entertainment from any company with which
                    a Fund has current or prospective business dealings,  unless
                    such entertainment is business-related,  reasonable in cost,
                    appropriate as to time and place,  and not so frequent as to
                    raise any question of impropriety.

IV.      DISCLOSURE AND COMPLIANCE

           Each Covered Officer shall:

               o    be  familiar  with  the  disclosure  requirements  generally
                    applicable to the Funds;

               o    not knowingly misrepresent, or cause others to misrepresent,
                    facts  about any Fund to others,  whether  within or outside
                    the Fund,  including to the Fund's trustees or directors and
                    auditors, and to governmental regulators and self-regulatory
                    organizations;

               o    to  the   extent   appropriate   within   his/her   area  of
                    responsibility, consult with other officers and employees of
                    the Funds and the adviser with the goal of  promoting  full,
                    fair, accurate,  timely and understandable disclosure in the
                    reports and documents the Funds file with, or submit to, the
                    SEC and in other  public  communications  made by the Funds;
                    and

               o    promote  compliance  with  the  standards  and  restrictions
                    imposed by applicable laws, rules and regulations.


V.       REPORTING AND ACCOUNTABILITY

           Each Covered Officer must:

               o    upon  adoption  of the Code (or  after  becoming  a  Covered
                    Officer),  affirm in writing  to the Board  that  he/she has
                    received, read and understands the Code;

               o    annually   affirm   to  the   Board   compliance   with  the
                    requirements of the Code;

               o    not  retaliate  against  any other  Covered  Officer  or any
                    employee  of the  Funds  or  their  affiliated  persons  for
                    reports of potential violations that are made in good faith;

               o    notify the Chief Compliance Officer promptly if he/she knows
                    of any violation of this Code; and

               o    respond  to   questionnaires   circulated   periodically  in
                    connection with the preparation of disclosure  documents for
                    the Funds.


     The Chief Compliance Officer shall maintain records of all activities
related to this Code.

           The Funds will follow the procedures set forth below in investigating
and enforcing this Code:

               o    The  Chief  Compliance  Officer  will  take all  appropriate
                    action to investigate  any potential  violation  reported to
                    him/her;

               o    If, after such  investigation,  the Chief Compliance Officer
                    determines  that  no  violation  has  occurred,   the  Chief
                    Compliance  Officer will notify the person(s)  reporting the
                    potential  violation,  and the Chief Compliance Officer will
                    report his/her conclusions to the Audit Committee;

               o    Any matter that the Chief Compliance  Officer determines may
                    be a violation will be reported to the Audit Committee;

               o    If the  Audit  Committee  determines  that a  violation  has
                    occurred,  it will inform and make a  recommendation  to the
                    Board,  which will consider  appropriate  action,  which may
                    include  review  of,  and  appropriate   modifications   to,
                    applicable  policies  and  procedures;  notification  to the
                    Chief Executive Officer of the Funds; or a recommendation to
                    sanction or dismiss the Covered Officer;

               o    The Audit Committee will be responsible for granting waivers
                    in its sole discretion;

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


           The Chief Compliance Officer shall:

               o    report  to  the  Audit  Committee  quarterly  any  approvals
                    provided in accordance with Section III of this Code; and

               o    report to the Audit  Committee  quarterly any violations of,
                    or material issues arising under, this Code.


VI.      OTHER POLICIES AND PROCEDURES

           This Code shall be the sole code of ethics adopted by the Funds for
   the purposes of Section 406 of the Sarbanes-Oxley Act and the rules and forms
   applicable to registered investment companies thereunder. Insofar as other
   polices or procedures of the Funds or the Funds' Service Providers govern or
   purport to govern the behavior or activities (including, but not limited to,
   personal trading 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 Funds' and their investment
   advisers' and principal underwriter's codes of ethics under Rule 17j-1 under
   the Company Act and any policies and procedures of the Service Providers are
   separate requirements applicable to the Covered Officers and are not part of
   this Code.

VII.     AMENDMENTS

           All material amendments to this Code must be approved or ratified by
   the Board, including a majority of independent directors or trustees.

VIII.    CONFIDENTIALITY

           All reports and records prepared or maintained pursuant to this Code
   will be considered confidential and shall be maintained and protected
   accordingly.

IX.      INTERNAL USE

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