Exhibit (a)(1)


                                 CODE OF ETHICS
              FOR PRINCIPAL EXECUTIVE AND SENIOR FINANCIAL OFFICERS
                   OF THE FLEX-FUNDS AND MEEDER ADVISOR FUNDS

     This Code of Ethics for Principal Executive and Senior Financial Officers
(referred to in this document as the "Code") has been adopted by The Flex-funds
and Meeder Advisor Funds (each referred to herein as the "Company"), on behalf
of their respective series (individually, a "Fund" and collectively, the
"Funds") to effectuate compliance with Section 406 under the Sarbanes-Oxley Act
of 2002 and the rules adopted pursuant to Section 406.

     This Code applies to the Company's principal executive officer, principal
financial officer, principal accounting officer, or persons performing similar
functions ("Covered Officers"). A listing of positions currently within the
ambit of Covered Officers is attached as EXHIBIT A./1/

1.   Purpose of the Code

     This Code sets forth standards and procedures that are reasonably designed
to deter wrongdoing and promote:

     .    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 a Fund files with, or submits to, the U.S.
          Securities and Exchange Commission ("SEC") and in other public
          communications made by the Company;

     .    compliance with applicable governmental laws, rules and regulations;

- ----------------------
/1/  The obligations imposed by this Code on Covered Officers are separate from
and in addition to any obligations that may be imposed on such persons as
Covered Persons under the Code of Ethics adopted by the Company, under Rule
17j-1 of the Investment Company Act of 1940, as amended, and any other code of
conduct applicable to Covered Officers in whatever capacity they serve. This
Code does not incorporate by reference any provisions of the Rule 17j-1 Code of
Ethics and accordingly, any violations or waivers granted under the Rule 17j-1
Code of Ethics will not be considered a violation or waiver under this Code.



     .    the prompt internal reporting of violations of this Code to the Code
          Administrator identified below; and

     .    accountability for adherence to this Code.

     In general, the principles that govern honest and ethical conduct,
including the avoidance of conflicts of interest between personal and
professional relationships, reflect, at the minimum, the following: (1) the duty
at all times in performing any responsibilities as the Company financial
officer, accountant or principal executive officer to place the interests of the
Company ahead of personal interests; (2) the fundamental standard that Covered
Officers should not take inappropriate advantage of their positions; (3) the
duty to assure that the Company's financial statements and reports to its
shareholders are prepared honestly and accurately in accordance with applicable
rules, regulations and accounting standards; and (4) the duty to conduct the
Company's business and affairs in an honest and ethical manner. Each Covered
Officer should be sensitive to situations that may give rise to actual as well
as apparent conflicts of interest.

     Although typically not presenting an opportunity for improper personal
benefit, conflicts arise from, or as a result of, the contractual relationship
between the Company and Meeder Asset Management, Inc. ("MAM") 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 the Company or MAM, or for both), be involved in
establishing policies and implementing decisions that will have different
effects on MAM and the Company. The participation of the Covered Officers in
such activities is inherent in the contractual relationship between the Company
and MAM and is consistent with the performance by the Covered Officers of their
duties as officers of the Company. Thus, if performed in conformity with the
provisions of the Investment Company Act of 1940 and the Investment Advisers Act
of 1940, such activities will be deemed to have been handled ethically. 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 of 1940 and
the Investment Advisers Act of 1940. This Code 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 Company.

2.   Prohibitions

     The specific provisions and reporting requirements of this Code are
concerned primarily with promoting honest and ethical conduct and avoiding
conflicts of interest in personal and professional relationships. No Covered
Officer may use information concerning the business and affairs of a Fund,
including the investment intentions of a Fund, or use his or her ability to
influence such investment intentions, for personal gain to himself or herself,
his or her family or friends or any other person or in a manner detrimental to
the interests of a Fund or its shareholders.

                                       2



     No Covered Officer may use his or her personal influence or personal
relationships to influence the preparation and issuance of financial reports of
a Fund whereby the Covered Officer would benefit personally to the detriment of
the Fund and its shareholders.

     No Covered Officer shall intentionally for any reason take any action or
fail to take any action in connection with his or her official acts on behalf of
a Fund that causes the Fund to violate applicable laws, rules and regulations.

     No Covered Officer shall, in connection with carrying out his or her
official duties and responsibilities on behalf of a Fund:

     (i)    employ any device, scheme or artifice to defraud a Fund or its
            shareholders;

     (ii)   intentionally cause a Fund to make any untrue statement of a
            material fact or omit to state a material fact necessary in order
            to make the statements made, in light of the circumstances under
            which they are made, not misleading in its official documents,
            regulatory filings, financial statements or communications to the
            public;

     (iii)  engage in any act, practice, or course of business which operates or
            would operate as a fraud or deceit upon any Fund or its
            shareholders;

     (iv)   engage in any manipulative practice with respect to any Fund;

     (v)    use his or her personal influence or personal relationships to
            influence any business decision, investment decisions, or financial
            reporting by a Fund whereby the Covered Officer would benefit
            personally to the detriment of the Fund or its shareholders;

     (vi)   intentionally cause a Fund to fail to comply with applicable laws,
            rules and regulations, including failure to comply with the
            requirement of full, fair, accurate, understandable and timely
            disclosure in reports and documents that a Fund files with, or
            submits to, the SEC and in other public communications made by the
            Fund;

     (vii)  intentionally mislead or omit to provide material information to a
            Fund's independent auditors or to the Company's Board of Trustees or
            the officers of the Company or its investment adviser in connection
            with financial reporting matters;

     (viii) fail to notify the Code Administrator promptly if he or she becomes
            aware of any existing or potential violations of this Code or
            applicable laws;

     (ix)   retaliate against others for, or otherwise discourage the reporting
            of, actual or apparent violations of this Code; or

                                       3



     (x)  fails to acknowledge or certify compliance with this Code if requested
          to do so.
