EX-99 CODE ETH

                          CHESTNUT STREET EXCHANGE FUND
                   CODE OF ETHICS FOR PRINCIPAL EXECUTIVE AND
                            SENIOR FINANCIAL OFFICERS

The Managing General Partners of The Chestnut Street Exchange Fund (the "Fund")
has adopted this Code of Ethics (the "Code") for certain senior officers of the
Fund to guide and remind such officers of their responsibilities to the Fund,
and shareholders of the Fund. Such officers are expected to act in accordance
with the guidance and standards set forth in this Code.

I.    COVERED OFFICERS AND PURPOSE OF THE CODE

The Code applies to the Fund's President, who is the Fund's principal executive
officer, and the Treasurer, who is the Fund's principal financial officer, and
any persons performing similar functions on behalf of the Fund, regardless of
whether such persons are employed by the Fund or a third party (the "Covered
Officers") 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 is obligated to use his or her best efforts to promote the
factors listed above, 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.   ETHICAL HANDLING OF ACTUAL AND APPARENT CONFLICTS OF INTEREST

      A.    CONFLICTS OF INTEREST - GENERAL

            1.    A "conflict of interest" occurs when a Covered Officer's
                  private interest interferes with the interests of, or his or
                  her service to, the Fund and its shareholders, including if a
                  Covered Officer, or a member of his or her family, receives
                  improper personal benefits as a result of his or her position
                  with the Fund.

- --------


*    If a Covered Person becomes aware that information filed with the SEC or
     made available to the public contains any false or misleading information
     or omits to disclose necessary information, he or she shall promptly report
     it to the Audit Committee.

            2.    A conflict of interest generally arises if a Covered Officer,
                  or a member of his or her family, directly or indirectly
                  participates in any investment, interest, association,
                  activity or relationship that may impair or appear to impair
                  the Covered Officer's objectivity.

      B.    SCOPE

            This Code does not, and is not intended to, repeat or replace the
            following programs and procedures, and such conflicts that fall
            outside of the parameters of this Code:

            1.    Certain conflicts of interest already are subject to conflicts
                  of interest provisions in the Investment Company Act of 1940,
                  as amended (the "1940 Act"), and the Investment Advisers Act
                  of 1940 (the "Advisers Act").

            2.    The Fund's and the investment adviser's compliance programs
                  and procedures that are designed to prevent, or identify and
                  correct, violations of these provisions.

      C.    TYPES OF CONFLICTS

            1.    CONTRACTUAL RELATIONSHIPS

            Although typically not presenting an opportunity for improper
            personal benefit, conflicts arise from, or as a result of, the
            contractual relationship between the Fund, investment adviser, or
            service providers of which the Covered Officers may also be officers
            or employees. As a result, this Code recognizes that the Covered
            Officers may, in the normal course of their duties (whether formally
            for the Fund, for the investment adviser or for the service
            providers), be involved in establishing policies and implementing
            decisions that will have different effects on the Fund, the adviser
            and the administrator. The participation of the Covered Officers in
            such activities is inherent in the contractual relationship between
            the Fund and the investment adviser or administrator and is
            consistent with the performance by the Covered Officers of their
            duties as officers of the Fund. Thus, if performed in conformity
            with the provisions of the 1940 Act and the Advisers Act, such
            activities will be deemed to have been handled ethically.





            2.    OTHER INVESTMENT COMPANIES

            In addition, it is recognized by the Fund's Managing General
            Partners that the Covered Officers may also be officers or employees
            of one or more other investment companies covered by this or other
            codes.


            3.    ADDITIONAL CONFLICTS

            Other conflicts of interest may be covered by the Code, even if such
            conflicts of interest are not subject to provisions in the 1940 Act
            and the Advisers Act.

      D.    PERSONAL INTERESTS

      The major principle of this Code is that the personal interest of a
      Covered Officer should not be placed improperly before the interest of the
      Fund. The following list provides examples of conflicts of interest under
      the Code, but Covered Officers should keep in mind that this list is not
      exhaustive.

      Each Covered Officer must:

      -  not use his or her 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 the Fund;

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

      -  report at least annually affiliations or other relationships with the
         Fund, the investment adviser or the distributor, including any related
         conflict of interest.

      E.    REPORTING OF CONFLICTS

            1.    Required Disclosures

                  If certain conflict of interest situations are engaged in by
                  Covered Officers or by members of their family, these
                  conflicts of interest must be promptly discussed with the
                  Audit Committee. These conflicts of interest include:

                  -  service as a director on the board of any public or private
                     company;

                  -  the receipt of any non-nominal gifts in excess of $250.00;

                  -  the receipt of any entertainment from any company with
                     which the 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;

                  -  any ownership interest in, or any consulting or employment
                     relationship with, any of the Fund's service providers,
                     other than its investment adviser, principal underwriter,
                     administrator or any affiliated person thereof;

                  -  a direct or indirect financial interest in commissions,
                     transaction charges or spreads paid by the Fund for
                     effecting portfolio transactions or for selling or
                     redeeming shares other than an interest arising from the
                     Covered Officer's employment, such as compensation or
                     equity ownership; and

                  -  any other interest, relationship or matter that a Covered
                     Person or the Managing General Partners determine, in his
                     or her reasonable judgement, warrants disclosure.

            2.    Recommended Disclosures

                  There are potential conflict of interest situations, which may
                  be engaged in by Covered Officers or by members of their
                  family, that should be discussed with the Audit Committee. A
                  Covered Person should use reasonable judgement to determine if
                  a conflict, other than conflicts listed under section E(1), is
                  material and warrants disclosure to the Audit Committee.

III.  COMPLIANCE AND DISCLOSURE

      A.    COMPLIANCE

      Each Covered Officer should:

      1. familiarize himself or herself with the disclosure requirements
         generally applicable to the Fund;

      2. 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 directors and auditors, governmental regulators and
         self-regulatory organizations and any other organization;

      3. to the extent appropriate within his or her area of responsibility,
         consult with other officers and employees of the Fund, investment
         adviser and other service providers

         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

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

      B.    DISCLOSURE

            Unless otherwise required by law, this Code shall be disclosed as
            required by the SEC.


IV.   ACCOUNTABILITY

      Each Covered Officer must:

      -  upon adoption of the Code (or thereafter as applicable, upon becoming a
         Covered Officer), affirm in writing to the Managing General Partners on
         the certification attached hereto as Appendix A that he or she has
         received, read, and understands the Code;

      -  annually thereafter affirm to the Managing General Partners that he or
         she has complied with the requirements of the Code and reported any
         violations of the Code;

      -  not retaliate against any other Covered Officer or any employee of the
         Fund or their affiliated persons or the Fund's service providers for
         reports of potential violations that are made in good faith; and

      -  notify the Chairman of the Audit Committee promptly if he or she knows
         of any violation of this Code. Failure to do so is itself a violation
         of this Code.


V.    REPORTING PROCEDURES

      1.    RESPONSIBILITY**

            -  The Fund's Audit Committee 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 Fund's Audit Committee may consult Fund counsel in order to
               effectively discharge its responsibilities.


- --------
**   The Audit Committee may delegate its reporting procedures, responsibilities
     and investigation procedures to the Chairman of the Audit Committee.

      2.    INVESTIGATION PROCEDURES**

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

            -  The Audit Committee will take all appropriate action to
               investigate any potential violations of the Code;

            -  If, after such investigation, the Audit Committee believes that
               no violation has occurred, the Audit Committee is not required to
               take any further action;

            -  Any matter that the Audit Committee believes is a violation of
               this Code will be reported to the Managing General Partners; and

            -  If the Managing General Partners concur that a violation has
               occurred, it will take action which it considers appropriate.
               Such action may include a review of, and appropriate
               modifications to, applicable policies and procedures;
               notification to appropriate personnel of each service provider or
               its governing body; or a recommendation to dismiss the Covered
               Officer.

      3.    WAIVERS

            Any approvals or waivers, implicit or otherwise, sought by a Covered
            Person will be considered by the Audit Committee. Such Committee
            will be responsible for granting waivers, as appropriate; and any
            changes to or waivers of this Code will, to the extent required, be
            disclosed as provided by SEC rules.

            A waiver is the approval of a material departure from a provision of
            this Code. An implicit waiver is 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
            Managing General Partners of the Fund.

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 and the rules and forms applicable to
registered investment companies thereunder. Insofar as other policies or
procedures of the Fund, the investment adviser, distributor, or other 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 its investment adviser's and distributor's codes of ethics under Rule
17j-1 under the 1940 Act (see Exhibit A for a list of the investment adviser and
distributor of the Fund) 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 Managing General Partners.

VII.  CONFIDENTIALITY AND RECORDKEEPING

All reports and records 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 Audit Committee.

Subject to the confidentiality provisions above, the Fund will maintain and
preserve for a period of not less than six (6) years from the date of submission
or action is taken, the first two (2) years in an easily accessible place, a
copy of the Covered Officer's annual certifications and any information or
materials supplied to the Audit Committee that provided the basis for any
amendment or waiver to this Code or relating to any violation of the Code and
sanctions imposed for such violation, together with a written record of the
approval or action taken by the Managing General Partners.

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 any Fund, as to any fact,
circumstance, or legal conclusion.
