                     --------------------------------------
                       OF THE SARBANES-OXLEY ACT OF 2002
                       ---------------------------------
                      FOR PRINCIPAL EXECUTIVE AND SENIOR
                              FINANCIAL OFFICERS
                              ------------------

I. COVERED OFFICERS/PURPOSE OF THE CODE

   This Code of Ethics (this "Code") pursuant to Section 406 of the
Sarbanes-Oxley Act of 2002 has been adopted by Trust/1/ and applies to the
Trust's Principal Executive Officer, Principal Financial Officer and Principal
Accounting Officer or persons performing similar functions (the "Covered
Officers," as 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 Trust files with, or submits to, the Securities
      and Exchange Commission (the "SEC") and in other public communications
      made by the Trust;

  .   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 conflicts of interest.

II. COVERED OFFICERS SHOULD HANDLE ETHICALLY CONFLICTS OF INTEREST

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

   Certain conflicts of interest arise out of the relationships between Covered
Officers and the Trust and already are subject to conflict of interest
provisions in the Investment Company

- --------
/1/  References herein to the "Trust" shall refer to the Travelers Series
     Trust, the Capital Appreciation Fund, the High Yield Bond Trust, the
     Managed Assets Trust and/or the Money Market Portfolio, as relevant given
     the context.



Act of 1940 (including the regulations thereunder, the "1940 Act") and the
Investment Advisers Act of 1940 (including the regulations thereunder, the
"Investment Advisers Act"). For example, Covered Officers may not engage in
certain transactions (such as the purchase or sale of portfolio securities or
other property) with the Trust because of their status as "affiliated persons"
of the Trust. The compliance programs and procedures of the Trust and its
investment advisers and subadvisers (the "Service Providers"; each of the
investment advisers and subadvisers shall be referred to herein as the
"Affiliated Service Providers") 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. See also Section V 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 Trust and companies in the MetLife enterprise. As a
result, this Code recognizes that the Covered Officers will, in the normal
course of their duties (whether for the Trust or for an Affiliated Service
Provider, or for both), be involved in establishing policies and implementing
decisions that will have different effects on the Affiliated Service Providers
and the Trust. The participation of the Covered Officers in such activities is
inherent in the contractual relationships between the Trust and its Affiliated
Service Providers and is consistent with the performance by the Covered
Officers of their duties as officers of the Trust. Thus, if performed in
conformity with the provisions of the 1940 Act and the Investment Advisers Act,
other applicable laws and the Trust's organizational documents, such activities
will be deemed to have been handled ethically and not to have involved any
violation of this Code. In addition, it is recognized by the Trust's Boards of
Trustees (the "Board") that the Covered Officers may also be directors,
officers or employees of one or more other investment companies covered by this
or other codes and that such service, by itself, does not give rise to a
conflict of interest or to a violation of this Code.

   Other conflicts of interest are covered by the Code, even if such conflicts
of interest are not the subject of provisions of the 1940 Act and the
Investment 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 the Trust.

         Each Covered Officer must not:

        .   use his or her personal influence or personal relationships to
            influence investment decisions or financial reporting by the Trust
            whereby the Covered Officer would benefit personally to the
            detriment of the Trust and its shareholders;

        .   use his or her position with the Trust for private economic gain to
            himself or herself, his or her family or any other person, or in a
            manner detrimental to the interests of the Trust and its
            shareholders;

        .   exercise inappropriate influence in connection with his or her
            official duties that causes the Trust to violate applicable laws,
            rules and regulations;

                                      2



        .   cause the Trust to take action, or fail to take action, for the
            individual personal benefit of the Covered Officer rather than the
            benefit of the Trust; or

        .   retaliate against any other Covered Officer or any employee of the
            Trust or its Service Providers or other entities doing business
            with the Trust for reports of potential violations of this Code or
            applicable laws that are made in good faith.

   There are some relationships that should always be disclosed to the
Secretary of the Trust (the "Code Officer"). These relationships are listed
below:

        .   any ownership interest in, or any consulting or employment
            relationship with, any entities doing business with the Trust,
            other than an Affiliated Service Provider or an affiliate of an
            Affiliated Service Provider. This disclosure requirement shall not
            apply to or otherwise limit the ownership of publicly traded
            securities so long as the Covered Officer's ownership does not
            exceed more than 1% of the outstanding securities of the relevant
            class.

        .   a direct or indirect financial interest in commissions, transaction
            charges or spreads paid by the Trust for effecting portfolio
            transactions or for selling or redeeming shares other than an
            interest arising from the Covered Officer's employment with an
            Affiliated Service Provider or its affiliates. This disclosure
            requirement shall not apply to or otherwise limit (i) the ownership
            of publicly traded securities so long as the Covered Officer's
            ownership does not exceed more than 1% of the particular class of
            security outstanding or (ii) the receipt by an Affiliated Service
            Provider or its affiliate of research or other benefits in exchange
            for "soft dollars."

III.  DISCLOSURE AND COMPLIANCE

        .   Each Covered Officer should familiarize himself or herself with the
            disclosure requirements generally applicable to the Trust;

        .   each Covered Officer should not knowingly misrepresent, or cause
            others to misrepresent, facts about the Trust to others, whether
            within or outside the Trust, including to the Board and auditors,
            and to governmental regulators and self-regulatory organizations;

        .   each Covered Officer should, to the extent appropriate within his
            or her area of responsibility, consult with other officers and
            employees of the Trust, the Service Providers or their affiliates,
            auditors, other entities doing business with the Trust or with
            counsel to the Trust with the goal of promoting full, fair,
            accurate, timely and understandable disclosure in the reports and
            documents the Trust files with, or submits to, the SEC (which for
            the sake of clarity, does not include any sales literature,
            omitting prospectuses or "tombstone" advertising prepared by the
            Trust's principal underwriter) and in other public communications
            made by the Trust; and

                                      3



        .   it is the responsibility of each Covered Officer to promote
            compliance with the standards and restrictions imposed by
            applicable laws, rules and regulations by (i) adhering personally
            to such standards and restrictions and (ii) encouraging and
            counseling other persons involved with the Trust to adhere to such
            standards and restrictions.

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 the Trust that he
            or she has received, read, and understands the Code;

        .   annually thereafter affirm to the Trust that he or she has complied
            with the requirements of the Code;

        .   provide full and fair responses to all questions asked in any
            Director and Officer Questionnaire as well as with respect to any
            supplemental request for information; and

        .   notify the Code Officer promptly if he or she knows of any material
            violation of this Code. Failure to do so is itself a violation of
            this Code.

   The Code 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 Code Officer may consult
with internal or external counsel or accountants or members of the MetLife
Compliance Department to assist with the application and interpretation of this
Code.

   Requests for waivers from the Code shall be submitted in writing to the Code
Officer. The Audit Committee of the Board of Trustees shall be authorized to
grant waivers, as it deems appropriate. Any changes to or waivers of this Code
will, to the extent required, be disclosed as provided by SEC rules.

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

        .   the Code Officer will take all appropriate action to investigate
            any potential material violations reported to him or her, which may
            include the use of internal or external counsel, accountants or
            other personnel, including members of the MetLife Compliance
            Department;

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

        .   any matter that the Code Officer believes is a material violation
            will be reported to the President (if the violation is by someone
            other than the President), the

                                      4



            MetLife Compliance Department and Audit Committee of the Board of
            Trustees (the "Committee");

        .   if the Committee concurs that a material violation has occurred, it
            will consider appropriate action, which may include review of, and
            appropriate modifications to, applicable policies and procedures;
            notification to appropriate personnel of an Affiliated Service
            Provider or its board; and/or disciplinary action (which may
            include the dismissal of the Covered Officer as an officer or
            employee of the Trust);

V.     OTHER POLICIES AND PROCEDURES

   This Code shall be the sole code of ethics adopted by the Trust for purposes
of Section 406 of the Sarbanes-Oxley Act and the rules and forms applicable to
registered investment companies thereunder. The Trust and its Service
Providers' codes of ethics under Rule 17j-1 under the 1940 Act and the Service
Providers' more detailed compliance policies and procedures are separate
requirements applying to the Covered Officers and others, and are not part of
this Code.

VI.    AMENDMENTS

   Any amendments to this Code, other than amendments to Exhibit A, must be
                                                         ---------
approved or ratified by a majority vote of the Board.

VII.   INTERNAL USE

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