THE AIM FAMILY OF FUNDS
                              CODE OF ETHICS FOR
                                SENIOR OFFICERS

I.      INTRODUCTION

The Boards of Directors/Trustees ("Board") of The AIM Family of Funds (the
"Companies") have adopted this code of ethics (this "Code") applicable to their
Principal Executive Officer and Principal Financial and Accounting Officer (the
"Covered Officers") to 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 documents
      filed with the Securities and Exchange Commission ("SEC") and in other
      public communications;

  .   compliance with applicable governmental laws, rules and regulations;

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

  .   accountability for adherence to the Code.

II.     COVERED OFFICERS SHOULD ACT HONESTLY AND CANDIDLY

Each Covered Officer named in Exhibit A to this Code owes a duty to the
Companies to act with integrity. Integrity requires, among other things, being
honest and candid. Deceit and subordination of principle are inconsistent with
integrity.

   Each Covered Officer must:

  .   act with integrity, including being honest and candid while still
      maintaining the confidentiality of information where required by law or
      the Companies' policies;

  .   observe both the form and spirit of laws and governmental rules and
      regulations, accounting standards and policies of the Companies;

  .   adhere to a high standard of business ethics; and

  .   place the interests of the Companies before the Covered Officer's own
      personal interests.

Business practices Covered Officers should be guided by and adhere to these
fiduciary standards.



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

   GUIDING PRINCIPLES. A "conflict of interest" occurs when an individual's
private interest interferes with the interests of the Companies. A conflict of
interest can arise when a Covered Officer takes actions or has interests that
may make it difficult to perform his or her work for the Companies objectively
and effectively. For example, a conflict of interest would arise if a Covered
Officer, or a member or his family, receives improper personal benefits as a
result of his or her position in any of the Companies. In addition, investment
companies should be sensitive to situations that create apparent, but not
actual, conflicts of interest. Service to the Companies should never be
subordinated to personal gain and advantage.

   Certain conflicts of interest covered by this Code arise out of the
relationships between Covered Officers and the Companies that already are
subject to conflict of interest provisions in the Investment Company Act of
1940, as amended and the Investment Advisers Act of 1940, as amended. For
example, Covered Officers may not individually engage in certain transactions
(such as the purchase or sale of securities or other property) with the
Companies because of their status as "affiliated persons" of the Companies.
Therefore, as to the existing statutory and regulatory prohibitions on
individual behavior, they will be deemed to be incorporated in this Code and
therefore any material violation will also be deemed a violation of this Code.
Covered Officers must in all cases comply with applicable statutes and
regulations.

   As to conflicts arising from, or as a result of the contractual relationship
between, the Companies and the investment adviser of which the Covered Officers
are also officers or employees, it is recognized by the Board that, subject to
the adviser's fiduciary duties to the Companies, the Covered Officers will in
the normal course of their duties (whether formally for the Companies 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 Companies.
The Board recognizes that the participation of the Covered Officers in such
activities is inherent in the contractual relationship between the Companies
and the adviser and is consistent with the expectation of the Board of the
performance by the Covered Officers of their duties as officers of the
Companies. In addition, it is recognized by the Board that the Covered Officers
may also be officers or employees of other investment companies advised by the
same adviser and the codes which apply to senior officers of those investment
companies will apply to the Covered Officers acting in those distinct
capacities.

   Each Covered Officer must:

  .   avoid conflicts of interest wherever possible;

  .   handle any actual or apparent conflict of interest ethically;

  .   not use his or her personal influence or personal relationships to
      influence investment decisions or financial reporting by an investment
      company whereby the Covered Officer would benefit personally to the
      detriment of any of the Companies;

                                      2



  .   not cause an investment company to take action, or fail to take action,
      for the personal benefit of the Covered Officer rather than the benefit
      of such company;

  .   not use knowledge of portfolio transactions made or contemplated for an
      investment company to profit or cause others to profit, by the market
      effect of such transactions; and

  .   as described in more detail below, discuss any material transaction or
      relationship that could reasonably be expected to give rise to a conflict
      of interest with the Chief Legal Officer of the AIM Funds (the "Chief
      Legal Officer").

Some conflict of interest situations that should always be discussed with the
Chief Legal Officer, if material, include the following:

  .   any outside business activity that detracts from an individual's ability
      to devote appropriate time and attention to his or her responsibilities
      with the Companies;

  .   being in the position of supervising, reviewing or having any influence
      on the job evaluation, pay or benefit of any immediate family member;

  .   any direct ownership interest in, or any consulting or employment
      relationship with, any of the Companies' service providers, other than
      its investment adviser, distributor or other AMVESCAP affiliated entities
      and other than a de minimis ownership interest (for purposes of this
      section of the Code an ownership interest of 1% or less shall constitute
      a de minimis ownership interest, and an ownership interest of more than
      1% creates a rebuttable presumption that there may be a material conflict
      of interest); and

  .   a direct or indirect financial interest in commissions, transaction
      charges or spreads paid by the Companies for effecting portfolio
      transactions or for selling or redeeming shares, other than an interest
      arising from the Covered Officer's employment with AIM, its subsidiaries,
      its parent organizations and any affiliates or subsidiaries thereof, such
      as compensation or equity ownership, and other than an interest arising
      from a de minimis ownership interest in a company with which the
      Companies execute portfolios transactions or a company that receives
      commissions or other fees related to its sales and redemptions of shares
      of the Companies (for purposes of this section of the Code an ownership
      interest of 1% or less shall constitute a de minimis ownership interest,
      and an ownership interest of more than 1% creates a rebuttable
      presumption that there may be a material conflict of interest).

IV.     DISCLOSURE

Each Covered Officer is required to be familiar, and comply, with the
Companies' disclosure controls and procedures so that the Companies' subject
reports and documents filed with the SEC comply in all material respects with
the applicable federal securities laws and SEC rules. In addition, each Covered
Officer having direct or supervisory authority regarding these SEC filings or
the Companies' other public communications should, to the extent appropriate
within his area of responsibility, consult with other officers and employees of
the Companies and take other appropriate steps regarding these

                                      3



disclosures with the goal of making full, fair, accurate, timely and
understandable disclosure.

   Each Covered Officer must:

  .   familiarize himself/herself with the disclosure requirements applicable
      to the Companies as well as the business and financial operations of the
      Companies; and

  .   not knowingly misrepresent, or cause others to misrepresent, facts about
      the Companies to others, whether within or outside the Companies,
      including representations to the Companies' internal auditors,
      independent Directors/Trustees, independent auditors, and to governmental
      regulators and self-regulatory organizations.

V.      COMPLIANCE

It is the Companies' policy to comply in all material respects with all
applicable governmental laws, rules and regulations. It is the personal
responsibility of each Covered Officer to adhere to the standards and
restrictions imposed by those laws, rules and regulations, including those
relating to affiliated transactions, accounting and auditing matters.

VI.     REPORTING AND ACCOUNTABILITY

   Each Covered Officer must:

  .   upon receipt of the Code, sign and submit to the Chief Compliance Officer
      of the Companies an acknowledgement stating that he or she has received,
      read, and understands the Code.

  .   annually thereafter submit a form to the Chief Compliance Officer of the
      Companies confirming that he or she has received, read and understands
      the Code and has complied with the requirements of the Code.

  .   not retaliate against any employee or other Covered Officer for reports
      of potential violations that are made in good faith.

  .   notify the Chief Legal Officer promptly if he becomes aware of any
      existing or potential violation of this Code. Failure to do so is itself
      a violation of this Code.

Except as described otherwise below, the Chief Legal Officer is responsible for
applying this Code to specific situations in which questions are presented to
him or her and has the authority to interpret this Code in any particular
situation. The Chief Legal Officer shall take all action he or she considers
appropriate to investigate any actual or potential violations reported to him
or her.

The Chief Legal Officer is authorized to consult, as appropriate, with the
Chairman of the Audit Committees of the Board, counsel to the Companies and
counsel to the independent Directors/Trustees, and is encouraged to do so.

                                      4



The Chief Legal Officer is responsible for granting waivers and determining
sanctions, as appropriate. In addition, approvals, interpretations, or waivers
sought by the Covered Officers may also be considered by the Chairman of the
AIM Funds Audit Committees.

The Companies will follow these procedures in investigating and enforcing this
Code, and in reporting on the Code:

  .   the Chief Legal Officer will take all appropriate action to investigate
      any violations reported to him or her;

  .   violations and potential violations will be reported to the Chairman of
      the Audit Committees of the Board after such investigation;

  .   if the Chairman of the Audit Committees determines that a violation has
      occurred, he or she will inform the Board, which will take all
      appropriate disciplinary or preventive action;

  .   appropriate disciplinary or preventive action may include a letter of
      censure, suspension, dismissal or, in the event of criminal or other
      serious violations of law, notification to the SEC or other appropriate
      law enforcement authorities;

  .   the Chief Legal Officer will be responsible for granting waivers, as
      appropriate; and

  .   any changes to or waivers of this Code will, to the extent required, be
      disclosed on Form N-CSR as provided by SEC rules.

VII.    OTHER POLICIES AND PROCEDURES

The Companies' and the Advisers' and Principal Underwriters' codes of ethics
under Rule 17j-1 under the Investment Company Act and the Advisers' more
detailed policies and procedures set forth in its Compliance and Supervisory
Procedures Manual are separate requirements applying to Covered Officers and
others, and are not part of this Code.

VIII.   AMENDMENTS

This Code may not be amended except in written form, which is specifically
approved by a majority vote of the Companies' Board, including a majority of
independent Directors/Trustees.

IX.     CONFIDENTIALITY

All reports and records prepared or maintained pursuant to this Code shall 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 members of the Companies' Board, counsel to
the Companies, and counsel to the independent Directors/Trustees.
