                                     FORM OF
                   CODE OF ETHICS FOR PRINCIPAL EXECUTIVE AND
                            SENIOR FINANCIAL OFFICERS
                                 AUGUST 31, 2005

I.       COVERED OFFICERS/PURPOSE OF THE CODE


This code of ethics (this "Code") for each of MEMBERS Mutual Funds and the Ultra
Series Fund (each, a "Trust," and collectively, the "Trusts") has been adopted
by the board of trustees ("Board") for each Trust and applies to each Trust's
Principal Executive (i.e., each Trust's president) and Senior Financial (i.e.,
each Trust's treasurer and assistant treasurers) Officers (such persons are
hereinafter referred to collectively as the "Covered Officers," and each such
person is set forth in Exhibit A hereto) 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 registrant files with, or submits to,
            the SEC and in other public communications made by the Trusts;

         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.



The Board has adopted this Code for the purpose of furthering compliance with
Item 2 of Form N-CSR,(1) which implements Section 406 of the Sarbanes-Oxley Act
of 2002 (the "2002 Act").(2) Section 406 of the 2002 Act requires disclosure by
management investment companies that are registered with the Securities and
Exchange Commission

- --------
(1) Item 2 of Form N-CSR requires a registered management investment company to
    disclose annually whether, as of the end of the period covered by the
    report, that company has adopted a code of ethics that applies to the
    registrant's principal executive officer, principal financial officer,
    principal accounting officer, or controller, or persons performing similar
    functions. If the registrant has not adopted such a code of ethics, the
    registrant must explain why it has not done so. Under Item 2, the registrant
    also must: (1) file with the SEC a copy of such code as an exhibit to its
    annual report; (2) post the text of the code on it's internet website and
    disclose, in its annual report, its internet address, and the fact that it
    as posted the code on its website; or (3) undertake in its most recently
    filed semi-annual report on Form N-CSR to provide to any person without
    charge, upon request, a copy of the code and explain the manner in which
    this request may be made. Disclosure also is required of amendments to, or
    waivers (including implicit waivers) from, a provision of the code in the
    registrant's annual report on Form N-CSR or on the registrant's website. If
    the registrant intends to satisfy the disclosure requirement by posting this
    information on its website, the registrant will be required to disclose its
    internet address and such intention. Investment companies must make the
    disclosure discussed in this footnote irrespective of whether these officers
    are employed by the registrant or a third party.

(2) The SEC rules require disclosure only about whether the registrant has
    adopted a code of ethics in accordance with the 2002 Act, but, in view of
    the seniority of the officers covered by the Code, it has been deemed
    appropriate that the Trusts' respective Boards of Trustees also adopt this
    Code for the Trusts.





(the "SEC") under the Investment Company Act of 1940 (the "1940 Act"),
concerning a code of ethics for senior financial officers of these investment
companies.

ROLE OF THE DESIGNATED PERSONS. As set forth in greater detail below, the
Covered Officers shall report to the Vice President of Corporate Compliance for
CUNA Mutual Group, another designated senior legal or compliance officer of the
Trusts or of a company ("Control Company") in a control relationship to the
Trusts (as such term is defined under Section 2(a)(19) of the 1940 Act, a
designated senior legal or compliance officer of a Control Company of the
Trusts, or another appropriate designated person (each hereinafter referred to
as a "Designated Person").(3)

As discussed in footnote 3, given the seniority of the Covered Officers,
investigations, interpretations and waivers(4) regarding any existing, actual or
potential violation of this Code shall be the responsibility of the Designated
Person(s); except that interpretations or waivers sought by the President of the
affected Trusts shall be considered by the Audit Committee or the Board of
Trustees of such Trust.

NOT A 1940 ACT RULE 17J-1 CODE OF ETHICS. This Code is not adopted under, nor
intended to serve as a basis for complying with the requirements of, Rule 17j-1
under the 1940 Act.


II.      COVERED OFFICERS SHOULD ACT HONESTLY AND CANDIDLY

This Code is applicable to all Covered Officers of the Trusts. 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.

Each Covered Officer must:

         o  act with integrity, including being honest and candid while still
            maintaining the confidentiality of information where required by law
            of the Trust's policies;

         o  observe applicable laws and governmental rules and regulations,
            accounting standards and Trust policies;

         o  adhere to a high standard of business ethics; and

         o  place the interests of the Trust and its shareholders before the
            Covered Officer's own personal interests.

All activities of Covered Officers should be guided by and adhere to these
standards.

- ---------------
(3) The SEC has indicated that any Designated Person "should have sufficient
    status within the company to engender respect for the [C]ode and the
    authority to adequately deal with the persons subject to the [C]ode
    regardless of their stature in the company." In addition a Designated Person
    also may be a Trustee of a Trust who is not deemed to be an "interested
    person" of the Trust, as that term is defined under Section 2(a)(19) of the
    1940 Act (hereinafter, an "Independent Trustee"), the chairperson of the
    Audit Committee of the Board of Trustees ("Audit Committee") of a Trust, or
    even the counsel to the Independent Trustees, as appropriate.

(4) Item 2 of Form N-CSR defines "waiver" as "the approval by the registrant of
    a material departure from a provision of the code of ethics" and "implicit
    waiver," which also must be disclosed in the Form N-CSR, as "the
    registrant's failure to take action within a reasonable period of time
    regarding a material departure from a provision of the code of ethics that
    has been made known to an executive officer of the registrant."








III. COVERED OFFICERS SHOULD HANDLE ETHICALLY ACTUAL AND APPARENT CONFLICTS OF
     INTEREST


OVERVIEW. The 1940 Act is designed, in part, to address inherent conflicts of
interest that exist in the management of an investment company's assets by a
third party (i.e., the investment company's investment adviser). Similarly, the
Investment Advisers Act of 1940, as amended, (the "Advisers Act"), addresses
conflicts of interest faced by an investment adviser in the management of client
assets. The principles set forth in this section relating to conflicts of
interest reflect the fact that investment companies and investment advisers
thereof already are subject to prohibitions on certain activities, including
self-dealing, and substantial limitations regarding conflicts of interest by the
1940 Act and the Advisers Act and the SEC rules promulgated thereunder. In light
of the existing structural, statutory and regulatory environment for registered
investment companies, a code of ethics broader than necessary to meet the new
2002 Act code of ethics requirement may be unnecessary. This Code, however, is
intended to reflect the general principal recognizing the need to hold persons
responsible for managing other people's money to the highest standards of
integrity.


GUIDING PRINCIPLES. A "conflict of interest" occurs when a Covered Officer's
private interest interferes with the interests of, or his or her service to, a
Trust. A conflict of interest can arise when a Covered Officer has interests
that may make it difficult to perform that Covered Person's work related to the
Trust objectively. For example, a conflict of interest would arise if a Covered
Officer, or a member of his or her family, receives improper personal benefits
as a result of such Covered Officer's position in the Trust. Service to the
Trust should not be subordinated to personal gain and advantage.


Certain conflicts of interest arise out of the relationships between Covered
Officers and the Trust that already are subject to conflict of interest
provisions in the 1940 Act and 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 the Trust because of their status as
"affiliated persons" of the Trust, as that term is defined under Section 2(a)(3)
of the 1940 Act. The Trust's and the investment adviser's compliance programs
and procedures 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 Trust and the investment adviser 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
Trust or for the adviser, or for both), be involved in establishing policies and
implementing decisions which will have different effects on the adviser and the
Trust. The participation of the Covered Officers in such activities is inherent
in the contractual relationship between the Trust and the adviser and is
consistent with the performance by the Covered Officers of their duties as
officers of the Trust and, if addressed in conformity with the provisions of the
1940 Act and the






Advisers Act will be deemed to have been handled ethically. In addition, it is
recognized by the Board of Trust 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 in the Acts. In reading the following
examples of conflicts of interest under the Code, Covered Officers should keep
in mind that such a list cannot ever be exhaustive by covering every possible
scenario. It follows that 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:

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

         o  not cause a Trust to take action, or fail to take action, for the
            individual personal benefit of the Covered Officer rather than the
            benefit the Trust;

         o  not use material non-public knowledge of portfolio transactions made
            or contemplated for a Trust to profit or cause others to profit in
            contemplation of the market effect of such transactions;

         o  report at least annually on the Trust's "Trustees and Officers
            Questionnaire" any and all material transactions, affiliations or
            relationships that could reasonably expected to give rise to, or be
            related to, a conflict of interest; and

         o  handle any actual or apparent conflict of interest ethically.


Certain conflict of interest situations should always, if material, be discussed
with the Designated Persons. Examples of these include:

         o  service as a director or trustee on the board of any non-charitable
            or commercial company;

         o  the receipt of any gifts of more than de minimis value (i.e., gifts
            in excess of $100) from any person or entity that does business with
            or on behalf of a Trust;

         o  the receipt of any entertainment from any company with which a Trust
            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;

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

         o  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, such as compensation or equity ownership.

In addition, any activity or relationship that would present a conflict of
interest for a Covered Officer also would likely present a conflict for the
Covered Officer if a member of the Covered Officer's family engages in such an
activity or has such a relationship.

IV.      DISCLOSURE AND COMPLIANCE

         o  Each Covered Officer should be familiar with the disclosure
            requirements generally applicable to the Trusts;

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

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

         o  it is the responsibility of each Covered Officer to promote
            compliance with the standards and restrictions imposed by applicable
            laws, rules and regulations.

In addition, each Covered Officer is required to be familiar, and to comply,
with the relevant Trust's Disclosure Controls and Procedures in connection with
the 2002 Act so that the Trust's subject reports and documents filed with the
SEC comply in all material respects with the applicable federal securities laws
and SEC rules. Moreover, each Covered Officer having direct or supervisory
authority regarding these SEC filings or the relevant Trust's other public
communications, also should consult, to the extent appropriate within the
Covered Person's area of responsibility, with Control Company officers and
employees and take appropriate steps regarding such disclosures with the goal of
rendering such disclosures full, fair, accurate, timely and understandable.


V.       REPORTING AND ACCOUNTABILITY


Each Covered Officer must:

         o  upon adoption of the Code, sign and submit to the MCA Chief
            Compliance Officer a written acknowledgement that he or she has
            received, read, and understands the Code;

         o  annually thereafter affirm to the MCA Chief Compliance Officer in
            writing that he or she has complied with the requirements of the
            Code;

         o  not retaliate against any employee or Covered Officer for reports of
            potential violations that are made in good faith; and

         o  notify the Designated Person(s) promptly if he or she knows of any
            violation of this Code. Failure to do so is itself a violation of
            this Code.




Except as otherwise described below, the Designated Person(s) will be
responsible for applying this Code to specific situations in which questions are
presented under it and shall have the authority to interpret this Code in any
particular situation. The Designated Person(s) shall take all actions that such
Designated Person(s) may deem necessary and appropriate to investigate any
reported existing, actual or potential violations. Such actions will include
reporting any existing or actual violations of this Code to the MCA Chief
Compliance Officer, as well as reporting, when such Designated Person deems
necessary or appropriate, potential violations of this Code to the MCA Chief
Compliance Officer. In addition, any conflicts of interest that pertain to a
Trust's president shall be submitted for consideration to the Chief Compliance
Officer for CUNA Mutual Group (the "CCO"). The CCO shall be responsible for
making a recommendation as to any approvals or waivers sought by the President
of a Trust and shall refer such recommendation to the MCA Chief Compliance
Officer, which shall then follow such recommendation. The MCA Chief Compliance
Officer shall report, or cause to be reported, to each Trust's Board, on an
annual basis, any issues arising under this Code.


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

         o  Designated Person(s) will take all appropriate action to investigate
            any potential violations reported thereto;

         o  if, after such investigation, a Designated Person determines that no
            violation has occurred, he or she is not required to take any
            further action;

         o  any matter that a Designated Person determines is a violation will
            be reported to the MCA Chief Compliance Officer;

         o  if the MCA Chief Compliance Officer concurs that a violation has
            occurred, he or she will consider appropriate action, which may
            include review of, and appropriate modifications to, applicable
            policies and procedures, as well as notification to appropriate
            personnel of the investment adviser or its board, or of the affected
            Trust's Control Company. In addition, the MCA Chief Compliance
            Officer shall determine whether to refer the matter to the affected
            Trust's Board for a determination of whether to dismiss the Covered
            Officer is appropriate, if, in its judgment, such corrective action
            may be warranted;

         o  the Designated Person(s) will be responsible for granting waivers,
            as appropriate, and will make a report concerning such waivers to
            the MCA Chief Compliance Officer; and

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


VI.  OTHER POLICIES AND PROCEDURES


This Code shall be the sole code of ethics adopted by the Trusts for purposes of
Section 406 of the 2002 Act and the rules and forms applicable to registered
investment companies thereunder. Insofar as other policies or procedures of the
Trusts, the Trusts' adviser, principal underwriter, 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 superceded by this Code to the extent
that they overlap or conflict with the provisions of






this Code. The Trusts' and their investment adviser's and principal
underwriter's codes of ethics under Rule 17j-1 under the 1940 Act and the
Advisers Act are separate requirements applying to the Covered Officers and
others, and are not part of this Code.


VII.  AMENDMENTS


         Except as to Exhibit A, this Code may not be amended except in written
form, which is specifically approved or ratified by a majority vote of each
Trust's respective Board, including a majority of its independent 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. Except as otherwise required by law or this Code, such matters
shall not be disclosed to anyone other than the appropriate Board and their
counsel, the appropriate Trust and its adviser, the MCA Chief Compliance
Officer, Designated Person(s), appropriate personnel within the Office of the
General Counsel and other appropriate compliance personnel.


IX.  INTERNAL USE


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