AIM HIGH INCOME MUNICIPAL FUND

RISK/RETURN SUMMARY

INVESTMENT OBJECTIVE
The fund's investment objective is to achieve a high level of current income that is exempt from federal income taxes.

PRIMARY INVESTMENT STRATEGIES
The fund will invest, normally, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in municipal debt securities that (1) pay interest which is excluded from gross income for federal income tax purposes, and (2) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax.

The fund invests, normally, at least 80% of its assets in municipal debt securities that are rated BBB/Baa or lower by Standard & Poor's Ratings Services, Moody's Investors Service, Inc., or any other nationally recognized statistical rating organization (NRSRO), or are deemed by the portfolio managers to be of comparable quality to such rated securities. The fund may invest all of its assets in debt securities that are rated BB/Ba or lower by an NRSRO, or are determined by the portfolio managers to be of comparable quality to such rated securities. It may also invest up to 10% of its assets in defaulted securities. Securities rated BB/Ba or lower are below investment grade quality and are commonly known as "junk bonds". The portfolio managers seek to maintain an average credit quality of BB/Ba on the fund's portfolio.

In selecting securities for the fund's portfolio, the portfolio managers focus on municipal securities they believe have favorable prospects for high current income.

Please see "Investment Objective, Strategies and Risks" for additional information regarding the fund's investment strategies.

PRINCIPAL RISKS
Among the principal risks of investing in the fund, which could adversely affect its net asset value, yield and total return are:

Market Risk           High Yield Risk              Concentration Risk           Synthetic Municipal Securities Risk
Interest Rate Risk    Reinvestment Risk            Defaulted Securities Risk    Leverage Risk
Credit Risk           Municipal Securities Risk    Derivatives Risk             Management Risk

Please see "Investment Objective, Strategies and Risks" for a description of these risks.

There is a risk that you could lose all or a portion of your investment in the fund and that the income you may receive from your investment may vary. The value of your investment in the fund will rise and fall with the prices of the securities in which the fund invests. An investment in the fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.

PERFORMANCE TABLE

The following performance table compares the fund's performance to that of a broad-based securities market index, a style specific index and a peer group index. The fund's performance reflects payment of sales loads, if applicable. The indices may not reflect payment of fees, expenses or taxes. The fund is not managed to track the performance of any particular index, including the indices shown below, and consequently, the performance of the fund may deviate significantly from the performance of the indices shown below.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown for Class A only and after-tax returns for Class B and C will vary.

(1) The Lehman Brothers Municipal Bond Index covers municipal bonds with a minimum credit rating of Baa, an outstanding par value of at least $5 million and issued as a part of a transaction of at least $50 million USD. The bonds must have been issued after December 31, 1990, and have a remaining maturity of at least one year. The fund has also included the Lehman Brothers High Yield Municipal Bond Index, which the fund believes more closely reflects the performance of the types of securities in which the fund invests. In addition, the Lipper High Yield Municipal Debt Funds Index (which may or may not include the fund) is included for comparison to a peer group.

(2) The Lehman Brothers High Yield Municipal Bond Index includes bonds that are non-rated or rated Ba1 or below. They must have an outstanding par value of at least $3 million and be issued as part of a transaction of at least $20 million. The bonds must have a dated-date after December 31, 1990 and must be at least one year from their maturity date.

(3) The Lipper High Yield Municipal Debt Funds Index is an equally weighted representation of the largest funds in the Lipper High Yield Municipal Debt Funds category. These funds invest at least 50% of their assets in lower rated municipal debt issues.

(4) The average annual total return given is since the month-end closest to the inception date of the class with the longest performance history.

AIM HIGH INCOME MUNICIPAL FUND

(3) Effective May 1, 2008, the fund's investment advisor voluntarily agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses (excluding certain items discussed below) of Class A, Class B and Class C shares to 0.75%, 1.50% and 1.50% of average daily net assets, respectively. In determining the advisor's obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the Net Annual Fund Operating Expenses to exceed the numbers reflected above: (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary items; (v) expenses related to a merger or reorganization, as approved by the fund's Board of Trustees; and (vi) expenses that the fund has incurred but did not actually pay because of an expense offset arrangement. Currently, in addition to the expense reimbursement arrangement with Invesco Ltd., the expense offset arrangements from which the fund may benefit are in the form of credits that the fund receives from banks where the fund or its transfer agent has deposit accounts in which it holds uninvested cash. Those credits are used to pay certain expenses incurred by the fund. Voluntary fee waivers or reimbursements may be modified or discontinued at any time upon consultation with the Board of Trustees without further notice to investors.

If a financial institution is managing your account you may also be charged a transaction or other fee by such financial institution.

As a result of 12b-1 fees, long-term shareholders in the fund may pay more than the maximum permitted initial sales charge.

EXPENSE EXAMPLE
This example is intended to help you compare the costs of investing in different classes of the fund with the cost of investing in other mutual funds.

The expense example assumes you:
(i) invest $10,000 in the fund for the time periods indicated;
(ii) redeem all of your shares at the end of the periods indicated;
(iii) earn a 5% return on your investment before operating expenses each year;
(iv) incur the same amount in operating expenses each year (after giving effect to any applicable contractual fee waivers and/or expense reimbursements); and
(v) incur applicable initial sales charges (see "General Information--Choosing a Share Class" section of this prospectus for applicability of initial sales charge).

To the extent fees are waived and/or expenses are reimbursed voluntarily, your expenses will be lower. Although your actual returns and costs may be higher or lower, based on these assumptions your costs would be:

           1 YEAR    3 YEARS    5 YEARS    10 YEARS
------------------------------------------------------
Class A     $570       $772      $  991     $1,619
Class B      676        845       1,139      1,842(1)
Class C      276        545         939      2,041
------------------------------------------------------

You would pay the following expenses if you did not redeem your shares:

           1 YEAR    3 YEARS    5 YEARS    10 YEARS
------------------------------------------------------
Class A     $570       $772       $991      $1,619
Class B      176        545        939       1,842(1)
Class C      176        545        939       2,041
------------------------------------------------------

(1) Assumes conversion of Class B shares to Class A shares, which occurs on or about the end of the month which is at least 8 years after the date on which shares were purchased, lowering your annual fund operating expenses from that time on.

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The settlement agreement between Invesco Aim Advisors, Inc. and certain of its affiliates and the New York Attorney General requires Invesco Aim Advisors, Inc. and certain of its affiliates to provide certain hypothetical information regarding investment and expense information. The chart below is intended to reflect the annual and cumulative impact of the fund's expenses, including investment advisory fees and other fund costs, on the fund's return over a 10- year period. The example reflects the following:
- You invest $10,000 in the fund and hold it for the entire 10 year period;
- Your investment has a 5% return before expenses each year;
- Hypotheticals both with and without any applicable initial sales charge applied (see "General Information--Choosing a Share Class" section of this prospectus for applicability of initial sales charge); and
- There is no sales charge on reinvested dividends.

INVESTMENT OBJECTIVE, STRATEGIES AND RISKS

OBJECTIVE AND STRATEGIES

The fund's investment objective is to achieve a high level of current income that is exempt from federal income taxes. The fund's investment objective may be changed by the Board of Trustees without shareholder approval.

The fund seeks to meet its investment objective by investing, normally, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in municipal debt securities that (1) pay interest which is excluded from gross income for federal income tax purposes, and (2) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. The fund may invest up to 20% of its total assets in taxable securities.

The principal type of municipal debt securities purchased by the fund are municipal bonds, which include revenue bonds and general obligation bonds.

Municipal debt securities include debt obligations of states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies, and instrumentalities, authorities thereof, and multi-state agencies, issued to obtain funds for various public purposes. Synthetic municipal securities, which include variable rate instruments that are created when fixed rate bonds are coupled with a third party tender feature and variable tender fees are treated as municipal debt securities. Other securities held by the fund may be structured with demand features which have the effect of shortening the security's maturity.

The fund invests, normally, at least 80% of its assets, in municipal debt securities that are rated BBB/Baa or lower by Standard & Poor's Ratings Services, Moody's Investors Service, Inc., or any other nationally recognized statistical rating organization (NRSRO), or are deemed by the portfolio managers to be of comparable quality to such rated securities. The fund may invest all of its assets in debt securities that are rated BB/Ba or lower by an NRSRO, or are determined by the portfolio managers to be of comparable quality to such rated securities. It may also invest

AIM HIGH INCOME MUNICIPAL FUND

up to 10% of its assets in defaulted securities. Securities rated BB/Ba or lower are below investment grade quality and are commonly known as "junk bonds". The portfolio managers seek to maintain an average credit quality of BB/Ba on the fund's portfolio.

The fund may invest 25% or more of its assets in municipal securities issued by entities having similar characteristics, such as (a) securities the issuers of which are located in the same geographic area or securities where issuers' interest obligations are paid from revenues of similar projects, or (b) industrial development revenue bonds, including pollution control revenue bonds, housing finance agency bonds or hospital bonds. The fund may not, however, invest 25% or more of its total assets in industrial development revenue bonds, including pollution control revenue bonds, issued for companies in the same industry. The fund may, but does not currently intend to, invest 25% or more of its total assets in securities whose issuers are located in any of the following states: Arizona, California, Colorado, Connecticut, Florida, Illinois, Michigan, Massachusetts, New Hampshire, New Jersey, New York, Ohio, Pennsylvania and Texas.

The fund's investments in the types of securities described in this prospectus vary from time to time, and, at any time, the fund may not be invested in all types of securities described in this prospectus. Any percentage limitations with respect to assets of the fund are applied at the time of purchase.

The portfolio managers generally take a buy and hold approach while focusing on municipal securities they believe have favorable prospects for high current income. Many of the municipal securities in which the fund invests, such as revenue bonds, are typically issued by a public authority and the proceeds from such securities are used to build or renovate a specific project, such as an airport, a toll road, water and sewer works, hospitals or housing. The proceeds from the project--such as rents, tolls or user fees--are used to pay interest and principal on the municipal securities. Another type of municipal security in which the fund invests in are general obligation bonds. These bonds are repaid from a municipality's general revenues and are generally backed by the full faith and credit of the municipal issuer.

In selecting securities for the fund's portfolio, the portfolio managers initially focus on experienced project managers, as well as projects that the portfolio managers believe make good economic and business sense. Prior to investing in a municipal security, the portfolio managers and/or fund analysts generally: (i) review the industry and project financial statements, (ii) perform site visits to talk with management about the project and facility,
(iii) review independent appraisals of the project, (iv) review environmental and feasibility studies on the project, and (v) conduct cash flow analysis. Before purchasing a municipal security upon its initial issuance, the portfolio managers or analysts may negotiate key terms, such as calls and loan covenants, credit basis, and a fair price (coupon) for the municipal security. Following an investment in a municipal security, the portfolio managers or analysts normally maintain phone contact with project managers, make periodic site visits to determine it the project is likely to reach its goals, and review monthly and quarterly statements.

The portfolio managers consider selling a security: (i) if the issuer's credit quality declines, (ii) if the outlook for a project undergoes a negative change, (iii) to shorten or lengthen the fund's duration (a measure of the fund's price sensitivity to changes in interest rates), (iv) as a result of interest rate changes, or (v) to limit exposure to a sector or issuer.

The fund typically maintains a portion of its assets in cash, cash equivalents, high quality debt instruments, and/or money market funds advised by the fund's advisor. Depending upon the then-current investment environment, holding a relatively larger percentage of portfolio assets in such instruments may either assist or hinder the fund's relative performance and its ability to achieve its investment objective. The fund holds cash to handle its daily cash needs, which include payment of fund expenses, redemption requests and securities transactions. In order to respond to adverse market, economic or other conditions, the fund may assume a temporary defensive position and invest a relatively larger percentage of the fund's portfolio assets in cash, cash equivalents or high quality debt instruments.

RISKS

The principal risks of investing in the fund are:

Market Risk--The prices of and the income generated by securities held by the fund may decline in response to certain events, including those directly involving the issuers, or in the case of industrial development revenue bonds, the company for whose benefit the bonds are being issued; general economic and market conditions; regional or global economic instability; and interest rate fluctuations.

Interest Rate Risk--Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on specific characteristics of each bond.

Credit Risk--Credit risk is the risk of loss on an investment due to the deterioration of an issuer's financial health. Such a deterioration of financial health may result in a reduction of the credit rating of the issuer's securities and may lead to the issuer's inability to honor its contractual obligations including making timely payment of interest and principal. Credit ratings are a measure of credit quality. Although a downgrade or upgrade of a bond's credit ratings may or may not affect its price, a decline in credit quality may make bonds less attractive, thereby driving up the yield on the bond and driving down the price. Declines in credit quality may result in bankruptcy for the issuer and permanent loss of investment. Revenue bonds are generally not backed by the taxing power of the issuing municipality and therefore are subject to a higher degree of credit risk than general obligation bonds.

High Yield Risk--High yield risk is a form of credit risk. High yield bonds or "junk bonds" are bonds rated below investment grade or deemed to be of comparable quality. They are considered to be speculative investments with greater risk of failure to make timely payment of interest and principal (to default on their contractual obligations) than their investment grade counterparts. High yield bonds may exhibit increased price sensitivity and reduced liquidity generally and particularly during times economic downturn or volatility in the capital markets.

Reinvestment Risk--Reinvestment risk is the risk that a bond's cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. If interest rates decline, the underlying bond may rise in value, but the cash flows received from that bond may have to be invested at a lower interest rate.

Municipal Securities Risk--The value of, payment of interest and repayment of principal with respect to, and the ability of the fund to sell, a municipal security may be affected by constitutional amendments, legislative enactments, executive orders, administrative regulations and voter initiatives as well as the economics of the regions in which the issuers in which the fund invests are located. Municipal securities backed by current or anticipated revenues from a specific project or assets, such as revenue bonds, can be negatively affected by the discontinuance of the taxation supporting the project or assets or the inability to collect revenues for the project or from the assets. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result in a decline in the security's value. To the extent that a municipal security in which the fund invests is not heavily followed by the investment community or such security issue is relatively small, the security may be difficult to value or sell at a fair price.

Concentration Risk--Because many municipal securities are issued to finance similar projects, especially those relating to education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal securities market and the fund. Moreover, sizeable investments in securities issued to finance similar projects could involve an increased risk to the fund if economic or other factors adversely affect the viability of these projects.

Defaulted Securities Risk--The fund may invest in securities where the issuer has defaulted on the payment of interest and/or principal. Defaulted securities are speculative and involve substantial risks. Generally, the fund will invest in defaulted securities when the portfolio managers believe they offer significant potential for higher returns or can be exchanged for other securities that offer this potential. There can be no assurance that the fund will achieve these returns or that the issuer will make an exchange offer. The fund will generally not receive interest payments on defaulted securities and may incur costs to protect its investment. In addition, defaulted securities involve the substantial risk that principal will not be repaid. Defaulted securities and any securities received in an exchange for such securities may be subject to restrictions on resale.

Derivatives Risk--The value of "derivatives" or "synthetics"--so-called because their value "derives" from the value of an underlying asset (including an underlying security), reference rate or index--may rise or fall more rapidly than other investments. For some derivatives, it is possible to lose more than the amount invested in the derivative. Derivatives may be used to create synthetic exposure to an underlying asset or to hedge portfolio risk. If the fund uses derivatives to "hedge" a portfolio risk, it is possible that the hedge may not succeed. This may happen for various reasons, including unexpected changes in the value of the rest of the fund's portfolio. Over the counter derivatives are also subject to counterparty risk, which is the risk that the other party to the contract will not fulfill its contractual obligation to complete the transaction with the fund.

Synthetic Municipal Securities Risk--The tax-exempt character of the interest paid on synthetic municipal securities is based on the tax-exempt income stream from the collateral. The Internal Revenue Service has not ruled on this issue and could deem income derived from synthetic municipal securities to be taxable.

Leverage Risk--If the fund borrows money to finance investments, it is engaging in a practice known as "leveraging." If the prices of those investments decrease, or if the cost of borrowing exceeds any increases in the prices of those investments, the net asset value of the fund's shares will decrease faster than if the fund had not used leverage. To repay borrowings, the fund may have to sell investments at a time and at a price that is unfavorable to the fund. Interest on borrowings is an expense the fund would not otherwise incur. There can be no assurance that the fund will use leverage or should the fund use leverage, that the fund's leverage strategy will be successful.

Management Risk--There is no guarantee that the investment techniques and risk analyses used by the fund's portfolio manager(s) will produce the desired results.

investment portfolio, including but not limited to, purchases and sales of individual securities, portfolio construction techniques, portfolio risk assessment, and the management of daily cash flows in accordance with portfolio holdings.

OTHER INFORMATION

SALES CHARGES
Purchases of Class A shares of AIM High Income Municipal Fund are subject to the maximum 4.75% initial sales charge as listed under the heading "CATEGORY II Initial Sales Charges" in the "General Information--Initial Sales Charges (Class A Shares Only)" section of this prospectus. Certain purchases of Class A shares at net asset value may be subject to a contingent deferred sales charge. Purchases of Class B and Class C shares are subject to a contingent deferred sales charge. For more information on contingent deferred sales charges, see "General Information--Contingent Deferred Sales Charges (CDSCs)" section of this prospectus.

DIVIDENDS AND DISTRIBUTIONS

The fund expects that its distributions, if any, will consist primarily of income (most of which is expected to be exempt from federal income taxes).

DIVIDENDS

The fund generally declares dividends from net investment income on each business day and pays dividends, if any, monthly.

CAPITAL GAINS DISTRIBUTIONS

The fund generally distributes long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Capital gains distributions may vary considerably from year to year as a result of the fund's normal investment activities and cash flows.

SPECIAL TAX INFORMATION REGARDING THE FUND

In addition to the general tax information set forth under the heading "General Information--Taxes" in this prospectus, the following information describes the tax impact of certain dividends you may receive from the fund:

- You will not be required to include the "exempt-interest" portion of dividends paid by the fund in your gross income for federal income tax purposes. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax return.

- The fund may invest a portion of its assets in securities that pay income that is not tax-exempt. The fund also may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of non- corporate shareholders.

- The fund may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for you, and may invest up to 20% of its net assets in such securities and other taxable securities. The fund will try to avoid investments that result in taxable dividends.

- Exempt-interest dividends from the fund are taken into account when determining the taxable portion of your social security or railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.

- The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the fund for the particular days in which you hold shares.

- From time to time, proposals have been introduced before Congress that would have the effect of reducing or eliminating the federal tax exemption on municipal securities. If such a proposal were enacted, the ability of the fund to pay exempt-interest dividends might be adversely affected.

LIMITED FUND OFFERING

Due to the sometimes limited availability of certain municipal securities that meet the portfolio managers' investment process for the fund, the fund limited public sales of its shares to new investors, effective as of the close of business on September 21, 2007. The advisor has determined that there is currently an ample supply of the types of securities in which the fund invests to permit the fund to re-open to all investors commencing with the start of business on March 3, 2008 through the earlier of the close of business on or about August 29, 2008 or when the fund reaches $800 million in assets. Investors should note that the fund reserves the right to refuse any order that might disrupt the efficient management of the fund.

All investors who are invested in the fund as of the date on which the fund closed to new investors and remain invested in the fund may continue to make additional investments in their existing accounts and may open new accounts in their name. Additionally, the following types of investors may be allowed to open a new account in the fund, subject to the approval of Invesco Aim Distributors and the advisor.

- Retirement plans maintained pursuant to Section 401 of the Internal Revenue Code ("the Code");

- Retirement plans maintained pursuant to Section 403 of the Code, to the extent they are maintained by organizations established under Section 501(c)(3) of the Code;

- Non qualified deferred compensation plans maintained pursuant to Section 409A of the Code;

- Retirement plans maintained pursuant to Section 457 of the Code; and

- Qualified Tuition Programs maintained pursuant to Section 529 of the Code.

Future investments in the fund may also be made by or through brokerage firm wrap programs, subject to the approval of Invesco Aim Distributors and the advisor. Such plans and programs that are considering the fund as an investment option should contact Invesco Aim Distributors.

At the advisors' discretion, proprietary asset allocation funds may open new accounts in the fund. In addition, the fund's current portfolio managers and portfolio management team may also make investments in the fund.

The fund, upon consultation with the Board of Trustees, may resume sales of shares to other new investors on a future date if the advisor determines it is appropriate.

THE AIM FUNDS

General Information

In addition to the fund, Invesco Aim serves as investment advisor to many other mutual funds that are offered to retail investors. The following information is about all the AIM funds that offer retail share classes.

CHOOSING A SHARE CLASS

Each of the funds offer multiple classes of shares. Each class represents an interest in the same portfolio of investments. Certain classes have higher expenses than other classes which may lower the return on your investment when compared to a less expensive class. In deciding which class of shares to purchase, you should consider the following attributes of the various share classes, among other things: (i) the eligibility requirements that apply to purchases of a particular class, (ii) the initial sales charges and contingent deferred sales charges (CDSCs), if any, applicable to the class, (iii) the 12b-1 fee, if any, paid by the class, and (iv) any services you may receive from a financial intermediary. Please contact your financial advisor to assist you in making your decision. Please refer to the prospectus fee table for more information on the fees and expenses of a particular fund's share classes. In addition to the share classes shown in the chart below, AIM Money Market Fund offers AIM Cash Reserve Shares and AIM Summit Fund offers Class P shares.

(4) Class C shares of AIM Floating Rate Fund have a 12b-1 fee of 0.75%.

SHARE CLASS ELIGIBILITY

CLASS A, A3, B, C AND AIM CASH RESERVE SHARES

Class A, A3, B, C and AIM Cash Reserve Shares are available to all retail investors, including individuals, trusts, corporations and other business and charitable organizations and employee benefit plans. The share classes offer different fee structures which are intended to compensate financial intermediaries for services provided in connection with the sale of shares and continued maintenance of the customer relationship. You should consider the services provided by your financial advisor and any other intermediaries who will be involved in the servicing of your account when choosing a share class.

Class B shares are not available as an investment for retirement plans maintained pursuant to Section 401 of the Internal Revenue Code (the Code). These plans include 401(k) plans (including AIM Solo 401(k) plans), money purchase pension plans and profit sharing plans. However, plans that have existing accounts invested in Class B shares will continue to be allowed to make additional purchases.

CLASS P SHARES

In addition to the other share classes discussed herein, the AIM Summit Fund offers Class P shares, which were historically sold only through the AIM Summit Investors Plans I and II (each a Plan and, collectively, the Summit Plans). Class P shares are sold with no initial sales charge and have a 12b-1 fee of 0.10%. However, Class P shares are not sold to members of the general public. Only shareholders who had accounts in the Summit Plans at the close of business on December 8, 2006 may purchase Class P shares and only until the total of their combined investments in the Summit Plans and in Class P shares directly equals the face amount of their former Plan under the 30 year extended investment option. The face amount of a Plan is the combined total of all scheduled monthly investments under the Plan. For a Plan with a scheduled monthly investment of $100.00, the face amount would have been $36,000.00 under the 30 year extended investment option.

A-1

THE AIM FUNDS

CLASS R SHARES

Class R shares are generally available only to employee benefit plans. These may include, for example, retirement and deferred compensation plans maintained pursuant to Sections 401, 403, and 457 of the Code; nonqualified deferred compensation plans; health savings accounts maintained pursuant to Section 223 of the Code; and voluntary employees' beneficiary arrangements maintained pursuant to Section 501(c)(9) of the Code. Retirement plans maintained pursuant to Section 401 generally include 401(k) plans, profit sharing plans, money purchase pension plans, and defined benefit plans. Retirement plans maintained pursuant to Section 403 must be established and maintained by non-profit organizations operating pursuant to Section 501(c)(3) of the Code in order to purchase Class R shares. Class R shares are generally not available for individual retirement accounts (IRAs) such as traditional, Roth, SEP, SAR-SEP and SIMPLE IRAs.

INVESTOR CLASS SHARES

Some of the funds offer Investor Class shares. Investor Class shares are sold with no initial sales charge and have a maximum 12b-1 fee of 0.25%. Investor Class shares are not sold to members of the general public. Only the following persons may purchase Investor Class shares:

- Investors who established accounts prior to April 1, 2002, in Investor Class shares who have continuously maintained an account in Investor Class shares (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons). These investors are referred to as "grandfathered investors."

- Customers of certain financial intermediaries which have had relationships with the funds' distributor or any funds that offered Investor Class shares prior to April 1, 2002, who have continuously maintained such relationships. These intermediaries are referred to as "grandfathered intermediaries."

- Employee benefit plans; provided, however, that retirement plans maintained pursuant to Section 403 must be established and maintained by non-profit organizations operating pursuant to Section 501(c)(3) of the Code in order to purchase Investor Class shares, unless the plan is considered a grandfathered investor or the account is opened through a grandfathered intermediary. Investor Class shares are generally not available for IRAs, unless the IRA depositor is considered a grandfathered investor or the account is opened through a grandfathered intermediary.

- Any trustee, director, officer or employee of any fund or of Invesco Ltd. or any of its subsidiaries or affiliates, or any employee benefit plan maintained by any of them (this includes any immediate family members of such persons).

DISTRIBUTION AND SERVICE (12B-1) FEES

Except as noted below, each fund has adopted a distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a fund to pay distribution fees to Invesco Aim Distributors, Inc. (Invesco Aim Distributors) to compensate or reimburse, as applicable, Invesco Aim Distributors for its efforts in connection with the sale and distribution of the fund's shares and for services provided to shareholders, all or a substantial portion of which are paid to the dealer of record. Because the funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

The following funds and share classes do not have 12b-1 plans:

- AIM Tax-Free Intermediate Fund, Class A shares.

- AIM Money Market Fund, Investor Class shares.

- AIM Tax-Exempt Cash Fund, Investor Class shares.

- Premier Portfolio, Investor Class shares.

- Premier U.S. Government Money Portfolio, Investor Class shares.

- Premier Tax-Exempt Portfolio, Investor Class shares.

INITIAL SALES CHARGES (CLASS A SHARES ONLY)

The funds are grouped into four categories for determining initial sales charges. The "Other Information" section of each fund's prospectus will tell you the sales charge category in which the fund is classified. As used below, the term "offering price" with respect to all categories of Class A shares includes the initial sales charge.

CLASS A SHARES SOLD WITHOUT AN INITIAL SALES CHARGE

Certain categories of investors are permitted to purchase and certain intermediaries are permitted to sell Class A shares of the funds without an initial sales charge because their transactions involve little or no expense. The investors who are entitled to purchase Class A shares without paying an initial sales charge include the following:

- Any current or retired trustee, director, officer or employee of any fund or of Invesco Ltd. or any of its subsidiaries or affiliates, or any foundation, trust or employee benefit plan maintained by any of them (this includes any immediate family members of such persons).

- Any registered representative or employee of any intermediary who has an agreement with Invesco Aim Distributors to sell shares of the funds (this includes any immediate family members of such persons).

- Any investor who purchases their shares through an approved fee-based program (this may include any type of account for which there is some alternative arrangement made between the investor and the intermediary to provide for compensation of the intermediary for services rendered in connection with the sale of the shares and maintenance of the customer relationship).

- Any investor who purchases their shares with the proceeds of a rollover, transfer or distribution from a retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor to another retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor, to the extent that such proceeds are attributable to the redemption of shares of a fund held through the plan or account.

- Employee benefit plans; provided, however, that they meet at least one of the following requirements:

a. the plan has assets of at least $1 million;

b. there are at least 100 employees eligible to participate in the plan; or

c. all plan transactions are executed through a single omnibus account per fund; further provided that retirement plans maintained pursuant to Section 403(b) of the Code are not eligible to purchase shares without paying an initial sales charge based on the aggregate investment made by the plan or the number of eligible employees unless the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code.

- Any investor who maintains an account in Investor Class shares of a fund (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons).

- Qualified Tuition Programs created and maintained in accordance with
Section 529 of the Code.

- Insurance company separate accounts.

No investor will pay an initial sales charge in the following circumstances:

- When buying Class A shares of AIM Tax-Exempt Cash Fund and Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund.

- When reinvesting dividends and distributions.

- When exchanging shares of one fund, that were previously assessed a sales charge, for shares of another fund.

- As a result of a fund's merger, consolidation, or acquisition of the assets of another fund.

Additional information regarding eligibility to purchase shares at reduced or without sales charges is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

You may qualify for reduced sales charges or sales charge exceptions. To qualify for these reductions or exceptions, you or your financial advisor must notify the transfer agent at the time of purchase that your purchase qualifies for such treatment. Certain individuals and employer-sponsored retirement plans may link accounts for the purpose of qualifying for lower initial sales charges. You or your financial consultant must provide other account numbers to be considered for Rights of Accumulation, or mark the Letter of Intent section on the account application, or provide other relevant documentation, so that the transfer agent can verify your eligibility for the reduction or exception. Please consult the fund's Statement of Additional Information for details.

Purchases of Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund, AIM Cash Reserve Shares of AIM Money Market Fund and Investor Class shares of any fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to Rights of Accumulation or Letters of Intent.

A-3

THE AIM FUNDS

RIGHTS OF ACCUMULATION

You may combine your new purchases of Class A shares of a fund with other fund shares currently owned (Class A, B, C, P or R) and investments in the AIM College Savings Plan(R) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of your current purchase and the public offering price of all other shares you own. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates. There may be other accounts that are eligible to be linked, as described in the fund's Statement of Additional Information. However, if the accounts are not registered in the same name with the same taxpayer identification number, you will have to contact the transfer agent to request that those accounts be linked. The transfer agent will not be responsible for identifying all accounts that may be eligible to be linked.

LETTERS OF INTENT

Under a Letter of Intent (LOI), you commit to purchase a specified dollar amount of Class A shares of one or more funds during a 13-month period. The amount you agree to purchase determines the initial sales charge you pay. If the full amount committed to in the LOI is not invested by the end of the 13-month period, your account will be assessed the higher initial sales charge that would normally be applicable to the amount actually invested.

REINSTATEMENT FOLLOWING REDEMPTION

If you redeem shares of a fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B and P redemptions may be reinvested only into Class A shares with no initial sales charge. This reinstatement privilege does not apply to:

- A purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account, or

- A purchase paid for with proceeds from the redemption of shares that were held indirectly through an employee benefit plan.

In order to take advantage of this reinstatement privilege, you must inform your financial advisor or the transfer agent that you wish to do so at the time of your investment.

CONTINGENT DEFERRED SALES CHARGES (CDSCS)

CDSCS ON CLASS A SHARES AND AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND

You can purchase $1,000,000 or more (a Large Purchase) of Class A shares of Category I, II and IV funds without paying an initial sales charge. However, if you redeem these shares prior to 18 months after the date of purchase, they will be subject to a CDSC of 1%.

If you currently own Class A shares of a Category I, II or IV fund, and make additional purchases without paying an initial sales charge that result in account balances of $1,000,000 or more, the additional shares purchased will be subject to an 18-month, 1% CDSC.

If Invesco Aim Distributors pays a concession to the dealer of record in connection with a Large Purchase of Class A shares by an employee benefit plan, the Class A shares may be subject to a 1% CDSC if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

If you acquire AIM Cash Reserve Shares of AIM Money Market Fund, Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.

CDSCS ON CLASS B SHARES AND ON CLASS C SHARES OF FUNDS OTHER THAN AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class B and Class C shares are sold without an initial sales charge. However, they are subject to a CDSC. If you redeem your shares during the CDSC period, you will be assessed a CDSC as follows, unless you qualify for one of the CDSC exceptions outlined below:

YEAR SINCE PURCHASE MADE:   CLASS B   CLASS C
-------------------------   -------   -------
First                           5%         1%

Fifth                           2      None
Sixth                           1      None
Seventh and following        None      None

CDSCS ON CLASS C SHARES -- EMPLOYEE BENEFIT PLAN

Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class C shares by an employee benefit plan; the Class C shares are subject to a 1.00% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

CDSCS ON CLASS C SHARES OF AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class C shares of AIM LIBOR Alpha Fund and AIM Short Term Bond Fund are not normally subject to a CDSC. However, if you acquired shares of those funds through an exchange, and the shares originally purchased were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC. Conversely, if you acquire Class C shares of any other fund as a result of an exchange involving Class C shares of

A-4

THE AIM FUNDS

AIM LIBOR Alpha Fund or AIM Short Term Bond Fund that were not subject to a CDSC, then the shares acquired as a result of the exchange will not be subject to a CDSC.

CDSCS ON CLASS R SHARES

Class R shares are not normally subject to a CDSC. However, if Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class R shares by an employee benefit plan, the Class R shares are subject to a 0.75% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

COMPUTING A CDSC

The CDSC on redemptions of shares is computed based on the lower of their original purchase price or current net asset value, net of reinvested dividends and capital gains distributions. In determining whether to charge a CDSC, shares are accounted for on a first-in, first-out basis, which means that you will redeem shares on which there is no CDSC first and, then, shares in the order of their purchase.

CDSC EXCEPTIONS

Investors who own shares that are otherwise subject to a CDSC will not pay a CDSC in the following circumstances:

- If you participate in the Systematic Redemption Plan and withdraw up to 12% of the value of your shares that are subject to a CDSC in any twelve-month period.

- If you redeem shares to pay account fees.

- If you are the executor, administrator or beneficiary of an estate or are otherwise entitled to assets remaining in an account following the death or post-purchase disability of a shareholder or beneficial owner and you choose to redeem those shares.

There are other circumstances under which you may be able to redeem shares without paying CDSCs. Additional information regarding CDSC exceptions is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

Shares acquired through the reinvestment of dividends and distributions are not subject to CDSCs.

The following share classes are sold with no CDSC:

- Class A shares of any Category III Fund.

- Class A shares of AIM Tax-Exempt Cash Fund.

- Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund.

- AIM Cash Reserve Shares of AIM Money Market Fund.

- Investor Class shares of any fund.

- Class P shares of AIM Summit Fund.

REDEMPTION FEES

Certain funds impose a 2% redemption fee (on redemption proceeds) if you redeem or exchange shares within 31 days of purchase. Please refer to the applicable fund's prospectus to determine whether that fund imposes a redemption fee. As of the date of this prospectus, the following funds impose redemption fees:

AIM Asia Pacific Growth Fund
AIM China Fund
AIM Developing Markets Fund
AIM European Growth Fund
AIM European Small Company Fund
AIM Floating Rate Fund
AIM Global Core Equity Fund
AIM Global Equity Fund
AIM Global Growth Fund
AIM Global Health Care Fund
AIM Global Real Estate Fund
AIM Global Small & Mid Cap Growth Fund
AIM Gold & Precious Metals Fund
AIM High Yield Fund
AIM International Allocation Fund
AIM International Core Equity Fund
AIM International Growth Fund
AIM International Small Company Fund
AIM International Total Return Fund
AIM Japan Fund
AIM Trimark Fund

The redemption fee will be retained by the fund from which you are redeeming or exchanging shares, and is intended to offset the trading costs, market impact and other costs associated with short-term money movements in and out of the fund. The redemption fee is imposed on a first-in, first-out basis, which means that you will redeem shares in the order of their purchase.

A-5

THE AIM FUNDS

Redemption fees generally will not be charged in the following circumstances:

- Redemptions and exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to assess the redemption fees.

- Redemptions and exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, variable insurance contracts or separately managed qualified default investment alternative vehicles maintained pursuant to Section 404(c)(5) of the Employee Retirement Income Security Act of 1974, as amended (ERISA), which use the funds as underlying investments.

- Redemptions and exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs or systematic withdrawal plans.

- Redemptions requested within 31 days following the death or post-purchase disability of an account owner.

- Redemptions or exchanges initiated by a fund.

The following shares are not subject to redemption fees, irrespective of whether they are redeemed in accordance with any of the exceptions set forth above:

- Shares acquired through the reinvestment of dividends and distributions.

- Shares acquired through systematic purchase plans.

- Shares acquired in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan to the trustee or custodian of another employee benefit plan.

Shares held by employee benefit plans will only be subject to redemption fees if the shares were acquired by exchange and are redeemed by exchange within 31 days of purchase.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

The funds have the discretion to waive the 2% redemption fee if a fund is in jeopardy of losing its registered investment company qualification for tax purposes.

Your financial advisor or other intermediary may charge service fees for handling redemption transactions. Your shares also may be subject to a CDSC in addition to the redemption fee.

PURCHASING SHARES

If you hold your shares through a financial advisor or other intermediary, your eligibility to purchase shares and the terms by which you may purchase, redeem and exchange shares may differ depending on that institution's policies.

MINIMUM INVESTMENTS

There are no minimum investments for Class P or R shares for fund accounts. The minimum investments for Class A, A3, B, C, and Investor Class shares for fund accounts are as follows:

Purchase orders will not be processed unless the account application and purchase payment are received in good order. In accordance with the USA PATRIOT Act, if you fail to provide all the required information requested in the current account application, your purchase order will not be processed. Additionally, federal law requires that the fund verify and record your identifying information.

SYSTEMATIC PURCHASE PLAN

You can arrange for periodic investments in any of the funds by authorizing the transfer agent to withdraw the amount of your investment from your bank account on a day or dates you specify and in an amount of at least $50 per fund. You may stop the Systematic Purchase Plan at any time by giving the transfer agent notice ten days prior to your next scheduled withdrawal. Certain financial advisors and other intermediaries may also offer systematic purchase plans.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic periodic exchanges, if permitted, from one fund to another fund or multiple other funds. The account from which exchanges are to be made must have a minimum balance of $5,000 before you can use this option. Exchanges will occur on (or about) the day of the month you specify, in the amount you specify. Dollar Cost Averaging cannot be set up for the 29th through the 31st of the month. The minimum amount you can exchange to another fund is $50. Certain financial advisors and other intermediaries may also offer dollar cost averaging programs. If you participate in one of these programs and it is the same or similar to Invesco Aim's Dollar Cost Averaging program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

AUTOMATIC DIVIDEND AND DISTRIBUTION INVESTMENT

Your dividends and distributions may be paid in cash or reinvested in the same fund or another fund without paying an initial sales charge. Unless you specify otherwise, your dividends and distributions will automatically be reinvested in the same fund. If you elect to receive your distributions by check, and the distribution amount is $10 or less, then the amount will be automatically reinvested in the same fund and no check will be issued. If you have elected to receive distributions by check, and the postal service is unable to deliver checks to your address of record, then your distribution election may be converted to having all subsequent distributions reinvested in the same fund and no checks will be issued. You should contact the transfer agent to change your distribution option, and your request to do so must be received by the transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

You must comply with the following requirements to be eligible to invest your dividends and distributions in shares of another fund:

- Your account balance in the fund paying the dividend or distribution must be at least $5,000; and

- Your account balance in the fund receiving the dividend or distribution must be at least $500.

PORTFOLIO REBALANCING PROGRAM

If you have at least $5,000 in your account, you may participate in the Portfolio Rebalancing Program. Under this Program, you can designate how the total value of your fund holdings should be rebalanced, on a percentage basis, between two and ten of your funds on a quarterly, semiannual or annual basis. Your portfolio will be rebalanced through the exchange of shares in one or more of your funds for shares of the same class of one or more other funds in your portfolio. Rebalancing will not occur if your portfolio is within 2% of your stated allocation. If you wish to participate in the Program, make changes or cancel the Program, the transfer agent must receive your request to participate, changes, or cancellation in good order at least five business days prior to the next rebalancing date, which is normally the 28th day of the last month of the period you choose. We may modify, suspend or terminate the Program at any time on 60 days' prior written notice to participating investors. Certain financial advisors and other intermediaries may also offer portfolio rebalancing programs. If you participate in one of these programs and it is the same as or similar to Invesco Aim's program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

RETIREMENT PLANS SPONSORED BY INVESCO AIM DISTRIBUTORS

Invesco Aim Distributors acts as the prototype sponsor for certain types of retirement plan documents. These plan documents are generally available to anyone wishing to invest plan assets in the funds. These documents are provided subject to terms, conditions and fees that vary by plan type.

REDEEMING SHARES

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call during the hours of the customary trading session of the New York Stock Exchange (NYSE) in order to effect the redemption at that day's net asset value. For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call before the last net asset value determination in order to effect the redemption that day.

THE AIM FUNDS

TIMING AND METHOD OF PAYMENT

We normally will send out payments within one business day, and in any event no more than seven days, after your redemption request is received in good order (meaning that all necessary information and documentation related to the redemption request have been provided to the transfer agent). If you redeem shares recently purchased by check or ACH, you may be required to wait up to ten business days before we send your redemption proceeds. This delay is necessary to ensure that the purchase has cleared. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted on the NYSE.

Redemption checks are mailed to your address of record, via first class U.S. mail, unless you make other arrangements with the transfer agent.

We use reasonable procedures to confirm that instructions communicated via telephone and the Internet are genuine, and we are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

EXPEDITED REDEMPTIONS (AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND ONLY)

If you place your redemption order by telephone, before 11:30 a.m. Eastern Time and request an expedited redemption, we will transmit payment of redemption proceeds on that same day via federal wire to a bank of record on your account. If we receive your redemption order after 11:30 a.m. Eastern Time and before the close of the customary trading session of the NYSE, we will transmit payment on the next business day.

SYSTEMATIC WITHDRAWALS

You may arrange for regular periodic withdrawals from your account in amounts equal to or greater than $50 per fund. We will redeem the appropriate number of shares from your account to provide redemption proceeds in the amount requested. You must have a total account balance of at least $5,000 in order to establish a Systematic Redemption Plan, unless you are establishing a Required Minimum Distribution for a retirement plan. You can stop this plan at any time by giving ten days prior notice to the transfer agent.

CHECK WRITING

The transfer agent provides check writing privileges for accounts in the following funds and share classes:

- AIM Money Market Fund, AIM Cash Reserve Shares and Investor Class shares

- AIM Tax-Exempt Cash Fund, Class A shares and Investor Class shares

- Premier Portfolio, Investor Class shares

- Premier Tax-Exempt Portfolio, Investor Class shares

- Premier U.S. Government Money Portfolio, Investor Class shares

You may redeem shares of these funds by writing checks in amounts of $250 or more if you have completed an authorization form. Redemption by check is not available for retirement accounts. Checks are not eligible to be converted to ACH by the payee. You may not give authorization to a payee by phone to debit your account by ACH for a debt owed to the payee.

SIGNATURE GUARANTEES

We require a signature guarantee in the following circumstances:

- When your redemption proceeds will equal or exceed $250,000 per fund.

- When you request that redemption proceeds be paid to someone other than the registered owner of the account.

- When you request that redemption proceeds be sent somewhere other than the address of record or bank of record on the account.

- When you request that redemption proceeds be sent to a new address or an address that changed in the last 30 days.

The transfer agent will accept a guarantee of your signature by a number of different types of financial institutions. Call the transfer agent for additional information. Some institutions have transaction amount maximums for these guarantees. Please check with the guarantor institution to determine whether the signature guarantee offered will be sufficient to cover the value of your transaction request.

REDEMPTIONS IN KIND

Although the funds generally intend to pay redemption proceeds solely in cash, the funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind).

If your account (Class A, A3, B, C, P and Investor Class shares only) has been open at least one year, you have not made an additional purchase in the account during the past six calendar months, and the value of your account falls below $500 for three consecutive months, the funds have the right to redeem the account after giving you 60 days' prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to $500 or by initiating a Systematic Purchase Plan.

If the fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the fund is not able to verify your identity as required by law, the fund may, at its discretion, redeem the account and distribute the proceeds to you.

EXCHANGING SHARES

You may, under certain circumstances, exchange shares in one fund for those of another fund. An exchange is the purchase of shares in one fund which

A-9

THE AIM FUNDS

is paid for with the proceeds from a redemption of shares of another fund effectuated on the same day. Accordingly, the procedures and processes applicable to redemptions of fund shares, as discussed under the heading "Redeeming Shares" above, will apply. Before requesting an exchange, review the prospectus of the fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the funds. If you wish to exchange shares of one fund for those of another fund, you must consult the prospectus of the fund whose shares you wish to acquire to determine whether the fund is offering shares to new investors and whether you are eligible to acquire shares of that fund.

PERMITTED EXCHANGES

Except as otherwise provided below under "Exchanges Not Permitted", you generally may exchange your shares for shares of the same class of another fund. The following below shows permitted exchanges:

     EXCHANGE FROM                             EXCHANGE TO
-----------------------   ------------------------------------------------------
AIM Cash Reserve Shares   Class A, A3, B, C, R, Investor Class
Class A                   Class A, A3, Investor Class, AIM Cash Reserve Shares
Class A3                  Class A, A3, Investor Class, AIM Cash Reserve Shares

Class C                   Class C
Class R                   Class R

EXCHANGES NOT PERMITTED

The following exchanges are not permitted:

- Investor Class shares cannot be exchanged for Class A shares of any fund which offers Investor Class shares.

- Exchanges into Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund (also known as the Category III funds) are not permitted.

- Class A Shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund cannot be exchanged for Class A3 Shares of those funds.

- AIM Cash Reserve Shares cannot be exchanged for Class B, C or R shares if the shares being exchanged were acquired by exchange from Class A shares of any fund.

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

- Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested; and

- If you have physical share certificates, you must return them to the transfer agent in order to effect the exchange.

Under unusual market conditions, a fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares. Any of the participating funds or the distributor may modify or terminate this privilege at any time.

LIMIT ON THE NUMBER OF EXCHANGES

You will generally be limited to four exchanges out of a fund per calendar year (other than the money market funds); provided, however, that the following transactions will not count toward the exchange limitation:

- Exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to apply the exchange limitation.

- Exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, and insurance company separate accounts which use the funds as underlying investments.

- Generally, exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs.

- Exchanges initiated by a fund or by the trustee, administrator or other fiduciary of an employee benefit plan (not in response to distribution or exchange instructions received from a plan participant).

Each fund reserves the discretion to accept exchanges in excess of these guidelines on a case-by-case basis if the fund, or its designated agent, believes that granting such exceptions would be consistent with the best interests of shareholders.

There is no limit on the number of exchanges out of AIM Limited Maturity Treasury Fund, AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio.

If you exchange shares of one fund for shares of multiple other funds as part of a single transaction, that transaction is counted as one exchange out of a fund.

INITIAL SALES CHARGES AND CDSCS APPLICABLE TO EXCHANGES

You may be required to pay an initial sales charge when exchanging from a fund with a lower initial sales charge than the one into which you are exchanging. If you exchange into shares that are subject to a CDSC, we will begin the holding period for purposes of calculating the CDSC on the date

A-10

THE AIM FUNDS

you made your initial purchase.

RIGHTS RESERVED BY THE FUNDS

Each fund and its agents reserve the right at any time to:

- Reject or cancel all or any part of any purchase or exchange order.

- Modify any terms or conditions related to the purchase, redemption or exchange of shares of any fund.

- Reject or cancel any request to establish a Systematic Purchase Plan, Systematic Redemption Plan or Portfolio Rebalancing Program.

- Suspend, change or withdraw all or any part of the offering made by this prospectus.

PRICING OF SHARES

DETERMINATION OF NET ASSET VALUE

The price of each fund's shares is the fund's net asset value per share. The funds value portfolio securities for which market quotations are readily available at market value. The funds value all other securities and assets for which market quotations are unavailable or unreliable at their fair value in good faith using procedures approved by the Boards of Trustees of the funds (collectively, the Board). The Board has delegated the daily determination of good faith fair value methodologies to Invesco Aim's Valuation Committee, which acts in accordance with Board approved policies. On a quarterly basis, Invesco Aim provides the Board various reports indicating the quality and effectiveness of its fair value decisions on portfolio holdings. Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day.

Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the NYSE and when the fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events which affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where market quotations are not readily available, including where Invesco Aim determines that the closing price of the security is unreliable, Invesco Aim will value the security at fair value in good faith using procedures approved by the Board. Fair value pricing may reduce the ability of frequent traders to take advantage of arbitrage opportunities resulting from potentially "stale" prices of portfolio holdings. However, it cannot eliminate the possibility of frequent trading.

Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. Fair value requires consideration of all appropriate factors, including indications of fair value available from pricing services. A fair value price is an estimated price and may vary from the prices used by other mutual funds to calculate their net asset values.

Invesco Aim may use indications of fair value from pricing services approved by the Board. In other circumstances, the Invesco Aim Valuation Committee may fair value securities in good faith using procedures approved by the Board. As a means of evaluating its fair value process, Invesco Aim routinely compares closing market prices, the next day's opening prices for the security in its primary market if available, and indications of fair value from other sources. Fair value pricing methods and pricing services can change from time to time as approved by the Board.

Specific types of securities are valued as follows:

Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.

Domestic Exchange Traded Equity Securities. Market quotations are generally available and reliable for domestic exchange traded equity securities. If market quotations are not available or are unreliable, Invesco Aim will value the security at fair value in good faith using procedures approved by the Board.

Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the fund may fair value the security. If an issuer specific event has occurred that Invesco Aim determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. Invesco Aim also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where Invesco Aim believes, at the approved degree of certainty, that the price is not reflective of current market value, Invesco Aim will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time.

Fund securities primarily traded on foreign markets may trade on days that are not business days of the fund. Because the net asset value of fund shares is determined only on business days of the fund, the value of the portfolio securities of a fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the fund.

Fixed Income Securities. Government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined

A-11

THE AIM FUNDS

without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Invesco Aim valuation committee will fair value the security using procedures approved by the Board.

Short-term Securities. The funds' short-term investments are valued at amortized cost when the security has 60 days or less to maturity. AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio value all their securities at amortized cost. AIM High Income Municipal Fund, AIM Municipal Bond Fund and AIM Tax-Free Intermediate Fund value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.

Futures and Options. Futures contracts are valued at the final settlement price set by the exchange on which they are principally traded. Options are valued on the basis of market quotations, if available.

Swap Agreements. Swap Agreements are fair valued using an evaluated quote provided by an independent pricing service. Evaluated quotes provided by the pricing service are based on a model that may include end of day net present values, spreads, ratings, industry and company performance.

Open-end Funds. To the extent a fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing fund will calculate its net asset value using the net asset value of the underlying fund in which it invests.

Each fund determines the net asset value of its shares on each day the NYSE is open for business (a business day), as of the close of the customary trading session, or earlier NYSE closing time that day. AIM Money Market Fund also determines its net asset value as of 12:00 noon Eastern Time on each business day. Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio determine the net asset value of their shares every fifteen minutes on each business day, beginning at 8:00 a.m. Eastern Time. The last net asset value determination on any business day for Premier Portfolio and Premier U.S. Government Money Portfolio will generally occur at 5:30 p.m. Eastern Time, and the last net asset value determination on any business day for Premier Tax-Exempt Portfolio will generally occur at 4:30 p.m. Eastern Time. Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio are authorized not to open for trading on a day that is otherwise a business day if the Federal Reserve Bank of New York and the Bank of New York, the fund's custodian, are not open for business or the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading and any such day will not be considered a business day. Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio also may close early on a business day if SIFMA recommends that government securities dealers close early. If Premier Portfolio, Premier Tax-Exempt Portfolio or Premier U.S. Government Money Portfolio uses its discretion to close early on a business day, the last net asset value calculation will occur as of the time of such closing.

From time to time and in circumstances deemed appropriate by Invesco Aim in its sole discretion, each of Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio may remain open for business, during customary business day hours, on a day that the NYSE is closed for business. In such event, on such day you will be permitted to purchase or redeem shares of such funds and net asset values will be calculated for such funds.

TIMING OF ORDERS

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, you can purchase or redeem shares on each business day prior to the close of the customary trading session or any earlier NYSE closing time that day. For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, purchase orders that are received and accepted before the close of the customary trading session or any earlier NYSE closing time on a business day generally are processed that day and settled on the next business day.

For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, you can purchase or redeem shares on each business day, prior to the last net asset value determination on such business day; however, if your order is received and accepted after the close of the customary trading session or any earlier NYSE closing time that day, your order generally will be processed on the next business day and settled on the second business day following the receipt and acceptance of your order.

For all funds, you can exchange shares on each business day, prior to the close of the customary trading session or any earlier NYSE closing time that day. Shareholders of Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio therefore cannot exchange their shares after the close of the customary trading session or any earlier NYSE closing time on a particular day, even though these funds remain open after such closing time.

The funds price purchase, exchange and redemption orders at the net asset value calculated after the transfer agent receives an order in good order. Any applicable sales charges are applied at the time an order is processed. A fund may postpone the right of redemption only under unusual circumstances, as allowed by the Securities and Exchange Commission, such as when the NYSE restricts or suspends trading.

TAXES

In general, if you are a taxable investor, dividends and distributions you receive are taxable as ordinary income or long-term capital gains for federal income tax purposes. This is true whether you reinvest distributions in additional fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from each fund during the prior year. Investors in tax-exempt funds should read the information under the heading "Other Information--Special Tax Information Regarding the Fund" in the applicable fund's prospectus. In addition, investors in taxable accounts should be aware of the following basic tax points:

A-12

THE AIM FUNDS

- Distributions of net short-term capital gains are taxable to you as ordinary income. A fund that is expected to have higher turnover than that of other funds is more likely to generate short-term gain or loss.

- Distributions of net long-term capital gains are taxable to you as long-term capital gains no matter how long you have owned your fund shares.

- If you are an individual and meet certain holding period requirements, a portion of income dividends paid by a fund may be designated as qualified dividend income eligible for taxation at long-term capital gain rates. These reduced rates generally are available for dividends paid by a fund out of dividends earned on the fund's investment in stocks of domestic corporations and qualified foreign corporations.

- Distributions declared to shareholders with a record date in December--if paid to you by the end of January--are taxable for federal income tax purposes as if received in December.

- Any long-term or short-term capital gains realized from redemptions of fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another fund is the same as a sale.

- If you invest in a fund shortly before it makes a capital gains distribution, the distribution will lower the value of the fund's shares by the amount of the distribution and, in effect, you will receive some of your investment back in the form of a taxable distribution. This is sometimes referred to as "buying a dividend."

- By law, if you do not provide a fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A fund also must withhold if the IRS instructs it to do so. When withholding is required, the amount will be 28% of any distributions or proceeds paid.

- Fund distributions and gains from sale or exchange of your fund shares generally are subject to state and local income taxes.

- Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits and estate taxes may apply to an investment in a fund.

The preceding discussion concerning the taxability of fund dividends and distributions and of redemptions and exchanges of fund shares is inapplicable to investors that are generally exempt from federal income tax, such as retirement plans that are qualified under Section 401, 403, 408, 408A and 457 of the Code, individual retirement accounts (IRAs) and Roth IRAs. You should consult your tax advisor before investing in a fund.

PAYMENTS TO FINANCIAL ADVISORS

The financial advisor or intermediary through which you purchase your shares may receive all or a portion of the sales charges and distribution fees discussed above. In addition to those payments, Invesco Aim Distributors or one or more of its corporate affiliates (collectively, Invesco Aim Affiliates) may make additional cash payments to financial advisors in connection with the promotion and sale of shares of the funds. These additional cash payments may include cash payments and other payments for certain marketing and support services. Invesco Aim Affiliates make these payments from their own resources, from Invesco Aim Distributors' retention of initial sales charges and from payments to Invesco Aim Distributors made by the funds under their 12b-1 plans. In this context, "financial advisors" include any broker, dealer, bank (including bank trust departments), registered investment advisor, financial planner, retirement plan administrator and any other financial intermediary having a selling, administration or similar agreement with Invesco Aim Affiliates.

Invesco Aim Affiliates make payments as incentives to certain financial advisors to promote and sell shares of the funds. The benefits Invesco Aim Affiliates receive when they make these payments include, among other things, placing the funds on the financial advisor's funds sales system, and access (in some cases on a preferential basis over other competitors) to individual members of the financial advisor's sales force or to the financial advisor's management. These payments are sometimes referred to as "shelf space" payments because the payments compensate the financial advisor for including the funds in its fund sales system (on its "sales shelf"). Invesco Aim Affiliates compensate financial advisors differently depending typically on the level and/or type of considerations provided by the financial advisor. The payments Invesco Aim Affiliates make may be calculated based on sales of shares of the funds (Sales-Based Payments), in which case the total amount of such payments shall not exceed 0.25% of the public offering price of all shares sold by the financial advisor during the particular period. Payments may also be calculated based on the average daily net assets of the applicable funds attributable to that particular financial advisor (Asset-Based Payments), in which case the total amount of such cash payments shall not exceed 0.25% per annum of those assets during a defined period. Sales-Based Payments primarily create incentives to make new sales of shares of the funds and Asset-Based Payments primarily create incentives to retain previously sold shares of the funds in investor accounts. Invesco Aim Affiliates may pay a financial advisor either or both Sales-Based Payments and Asset-Based Payments.

Invesco Aim Affiliates are motivated to make these payments as they promote the sale of fund shares and the retention of those investments by clients of financial advisors. To the extent financial advisors sell more shares of the funds or retain shares of the funds in their clients' accounts, Invesco Aim Affiliates benefit from the incremental management and other fees paid to Invesco Aim Affiliates by the funds with respect to those assets.

Invesco Aim Affiliates also may make payments to certain financial advisors for certain administrative services, including record keeping and sub-accounting of shareholder accounts pursuant to a sub-transfer agency, omnibus account service or sub-accounting agreement. All fees payable by Invesco Aim Affiliates under this category of services are charged back to the funds, subject to certain limitations approved by the Board.

You can find further details in the fund's Statement of Additional Information about these payments and the services provided by financial advisors. In certain cases these payments could be significant to the financial advisor. Your financial advisor may charge you additional fees or commissions other than those disclosed in this prospectus. You can ask your financial advisor about any payments it receives from Invesco Aim Affiliates or the funds, as well as about fees and/or commissions it charges.

EXCESSIVE SHORT-TERM TRADING ACTIVITY (MARKET TIMING) DISCLOSURES

While the funds provide their shareholders with daily liquidity, their investment programs are designed to serve long-term investors and are not designed to accommodate excessive short-term trading activity in violation of our policies described below. Excessive short-term trading activity in the funds' shares (i.e., a purchase of fund shares followed shortly thereafter by a redemption of such shares, or vice versa) may hurt the long-term performance of certain funds by requiring them to maintain an excessive amount of cash or to liquidate portfolio holdings at a disadvantageous time, thus interfering with the efficient management of such funds by causing them to incur increased brokerage and administrative costs. Where excessive short-term trading activity seeks to take advantage of arbitrage opportunities from stale prices for portfolio securities, the value of fund shares held by long-term investors may be diluted. The Board has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares for all funds except the money market funds. However, there is the risk that these funds' policies and procedures will prove ineffective in whole or in part to detect or prevent excessive or short-term trading. These funds may alter their policies at any time without prior notice to shareholders if the advisor believes the change would be in the best interests of long-term shareholders.

The Invesco Aim Affiliates currently use the following tools designed to discourage excessive short-term trading in the retail funds:

- Trade activity monitoring.

- Trading guidelines.

- Redemption fees on trades in certain funds.

- The use of fair value pricing consistent with procedures approved by the Board.

Each of these tools is described in more detail below. Although these tools are designed to discourage excessive short-term trading, you should understand that none of these tools alone nor all of them taken together eliminate the possibility that excessive short-term trading activity in the funds will occur. Moreover, each of these tools involves judgments that are inherently subjective. Invesco Aim Affiliates seek to make these judgments to the best of their abilities in a manner that they believe is consistent with long-term shareholder interests.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

Money Market Funds. The Board of AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio (the money market funds) have not adopted any policies and procedures that would limit frequent purchases and redemptions of such funds' shares. The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions, and determined that those risks were minimal. Nonetheless, to the extent that a money market fund must maintain additional cash and/or securities with short-term durations in greater amounts than may otherwise be required or borrow to honor redemption requests, the money market fund's yield could be negatively impacted.

The Board does not believe that it is appropriate to adopt any such policies and procedures for the money market funds for the following reasons:

- The money market funds are offered to investors as cash management vehicles; investors must perceive an investment in such funds as an alternative to cash, and must be able to purchase and redeem shares regularly and frequently.

- One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of the money market funds will be detrimental to the continuing operations of such funds.

- The money market funds' portfolio securities are valued on the basis of amortized cost, and such funds seek to maintain a constant net asset value. As a result, there are no price arbitrage opportunities.

- Because the money market funds seek to maintain a constant net asset value, investors expect to receive upon redemption the amount they originally invested in such funds. Imposition of redemption fees would run contrary to investor expectations.

AIM Limited Maturity Treasury Fund. The Board of AIM Limited Maturity Treasury Fund has not adopted any policies and procedures that would limit frequent purchases and redemptions of such fund's shares. The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions and determined that those risks were minimal. Nonetheless, to the extent that AIM Limited Maturity Treasury Fund must maintain additional cash and/or securities with short-term durations in greater amounts than may otherwise be required or borrow to honor redemption requests, AIM Limited Maturity Treasury Fund's yield could be negatively impacted.

The Board does not believe that it is appropriate to adopt any such policies and procedures for the fund for the following reasons:

A-14

THE AIM FUNDS

- Many investors use AIM Limited Maturity Treasury Fund as a short-term investment alternative and should be able to purchase and redeem shares regularly and frequently.

- One of the advantages of AIM Limited Maturity Treasury Fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of AIM Limited Maturity Treasury Fund will be detrimental to the continuing operations of such fund.

TRADE ACTIVITY MONITORING
Invesco Aim Affiliates monitor selected trades on a daily basis in an effort to detect excessive short-term trading activities. If, as a result of this monitoring, Invesco Aim Affiliates believe that a shareholder has engaged in excessive short-term trading, they will seek to act in a manner that they believe is consistent with the best interests of long-term investors, which may include taking steps such as (i) asking the shareholder to take action to stop such activities or (ii) refusing to process future purchases or exchanges related to such activities in the shareholder's accounts other than exchanges into a money market fund. Invesco Aim Affiliates will use reasonable efforts to apply the fund's policies uniformly given the practical limitations described above.

The ability of Invesco Aim Affiliates to monitor trades that are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent.

TRADING GUIDELINES

If you exceed four exchanges out of a fund per calendar year (other than the money market funds and AIM Limited Maturity Treasury Fund), or a fund or an Invesco Aim Affiliate determines, in its sole discretion, that your short-term trading activity is excessive (regardless of whether or not you exceed such guidelines), it may, in its discretion, reject any additional purchase and exchange orders.

The ability of Invesco Aim Affiliates to monitor exchanges made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent. If shares of the funds are held in the name of a conduit investment vehicle and not in the names of the individual investors who have invested in the funds through the conduit investment vehicle, the conduit investment vehicle may be considered an individual shareholder of the funds. To the extent that a conduit investment vehicle is considered an individual shareholder of the funds, the funds are likely to be limited in their ability to impose exchange limitations on individual transactions initiated by investors who have invested in the funds through the conduit investment vehicle.

REDEMPTION FEES

You may be charged a 2% redemption fee if you redeem, including redeeming by exchange, shares of certain funds within 31 days of purchase. The ability of a fund to assess a redemption fee on redemptions effectuated through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent.

FAIR VALUE PRICING

Securities owned by a fund are to be valued at current market value if market quotations are readily available. All other securities and assets of a fund for which market quotations are not readily available are to be valued at fair value determined in good faith using procedures approved by the Board. Fair value pricing may reduce the ability of frequent traders to take advantage of arbitrage opportunities resulting from potentially "stale" prices of portfolio holdings. However, it cannot eliminate the possibility of frequent trading.

AIM TAX-EXEMPT CASH FUND

RISK/RETURN SUMMARY

INVESTMENT OBJECTIVE
The fund's investment objective is to provide as high a level of tax-exempt income as is consistent with the preservation of capital and maintenance of liquidity.

PRIMARY INVESTMENT STRATEGIES

The fund invests only in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) municipal securities; and (ii) cash equivalents.

The fund invests, normally, at least 80% of its assets in debt securities that (1) pay interest that is excluded from gross income for federal income tax purposes, and (2) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax.

The fund invests in accordance with industry-standard requirements for money market funds for the quality, maturity and diversification of investments.

In selecting securities for the fund, the portfolio managers focus on safety, liquidity and yield.

Please see "Investment Objective, Strategies and Risks" for additional information regarding the fund's investment strategies.

PRINCIPAL RISKS
Among the principal risks of investing in the fund, which could adversely affect its net asset value, yield and total return are:

Market Risk               Credit Risk                  Foreign Credit Exposure Risk    Synthetic Municipal Securities Risk
Money Market Fund Risk    Municipal Securities Risk    Derivatives Risk                Management Risk
Interest Rate Risk        Concentration Risk

Please see "Investment Objective, Strategies and Risks" for a description of these risks.

Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund. Additionally, the fund's yield will vary as the short-term securities in its portfolio mature or are sold, and the proceeds are reinvested in securities with different interest rates. An investment in the fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.

EXPENSE EXAMPLE

This example is intended to help you compare the cost of investing in different classes the fund with the cost of investing in other mutual funds.

The expense example assumes you:

(i) invest $10,000 in the fund for the time periods indicated;
(ii) redeem all of your shares at the end of the periods indicated;
(iii) earn a 5% return on your investment before operating expenses each year; and
(iv) incur the same amount in operating expenses each year (after giving effect to any applicable contractual fee waivers and/or expense reimbursements).

To the extent fees are waived and/or expenses are reimbursed voluntarily, your expenses will be lower. Although your actual returns and costs may be higher or lower, based on these assumptions your costs would be:

                  1 YEAR    3 YEARS    5 YEARS    10 YEARS
-------------------------------------------------------------
Class A             $94       $325       $576      $1,292

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The settlement agreement between Invesco Aim Advisors, Inc. and certain of its affiliates and the New York Attorney General requires Invesco Aim Advisors, Inc. and certain of its affiliates to provide certain hypothetical information regarding investment and expense information. The chart below is intended to reflect the annual and cumulative impact of the fund's expenses, including investment advisory fees and other fund costs, on the fund's return over a 10- year period. The example reflects the following:
- You invest $10,000 in the fund and hold it for the entire 10 year period;
- Your investment has a 5% return before expenses each year;
- The fund's current annual expense ratio includes any applicable contractual fee waiver or expense reimbursement for the period committed; and
- There is no sales charge on reinvested dividends.

There is no assurance that the annual expense ratio will be the expense ratio for the fund classes for any of the years shown. To the extent that Invesco Aim Advisors, Inc. and certain of its affiliates make any fee waivers and/or expense reimbursements pursuant to a voluntary arrangement, your actual expenses may be less. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

(1) pay interest that is excluded from gross income for federal income tax purposes, and (2) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax.

The fund invests in accordance with industry-standard requirements for money market funds for the quality, maturity and diversification of investments.

The fund invests only in high-quality U.S. dollar-denominated short-term debt obligations, including: (i) municipal securities, which may include tax- exempt commercial paper; and (ii) cash equivalents. These securities may have credit and liquidity enhancements provided by banks, insurance companies or other financial institutions.

Municipal securities include debt obligations of states, territories and possessions of the United States and the District of Columbia, their political subdivisions, agencies, and instrumentalities, authorities thereof, and multi- state agencies, issued to obtain funds for various public purposes. Synthetic municipal securities, which include variable rate instruments that are created when fixed rate bonds are coupled with a third party tender feature and variable tender fees are treated as municipal securities. Other securities held by the fund may be structured with demand features which have the effect of shortening the security's maturity.

The fund invests only in municipal securities that are: (1) rated in the highest rating category by two nationally recognized statistical rating organizations (NRSRO); (2) rated by only one NRSRO, if they are rated in the highest category by that NRSRO; and (3) unrated but deemed to be of comparable quality by the advisors.

Some of the fund's investments, although U.S. dollar-denominated, may be subject to foreign credit exposure.

The fund may invest up to 20% of its net assets in money market instruments that may be subject to federal taxes, including Treasury securities, repurchase agreements, bankers' acceptances, commercial paper, U.S. dollar-denominated foreign securities and master notes.

The fund's investments in the types of securities described in this prospectus vary from time to time, and, at any time, the fund may not be invested in all types of securities described in this prospectus. Any percentage limitations with respect to assets of the fund are applied at the time of purchase.

In selecting securities for the fund's portfolio, the portfolio managers focus on safety, liquidity, and yield that is exempt from federal income taxes. The portfolio structure is driven to some extent by the supply and availability of municipal obligations. The portfolio managers manage liquidity by trading in daily and weekly variable-rate demand notes.

The portfolio managers consider selling a security: (i) if the issuer's credit quality declines, (ii) if a geographic region in which the issuer's in which the fund invests are located undergoes a negative change, (iii) as a result of interest rate changes, or (iv) to enhance yield.

The fund may maintain a portion of its assets in cash pending investment or to handle its daily cash needs, including payment of fund expenses, redemption requests and securities transactions. Depending upon the then-current investment environment, holding a relatively larger percentage of portfolio assets in cash may either assist or hinder the fund's relative performance.

RISKS
The principal risks of investing in the fund are:

Market Risk--The prices of and the income generated by securities held by the fund may decline in response to certain events, including those directly involving the issuers, or in the case of industrial development revenue bonds, the company for whose benefit the bonds are being issued; general economic and market conditions; regional or global economic instability; and interest rate fluctuations.

Money Market Fund Risk--The fund is a money market fund and an investment in the fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the fund seeks to preserve the value of an investment at $1.00 per share, it is possible to lose money by investing in the fund. Additionally, the fund's yield will vary as the short-term securities in its portfolio mature and the proceeds are reinvested in other securities.

Interest Rate Risk--Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on specific characteristics of each bond.

Credit Risk--There is a possibility that the issuers of instruments in which the fund invests will be unable to meet interest payments or repay principal. Changes in the financial strength of an issuer may reduce the credit rating of its securities and may decrease their value. Changes in the credit quality of financial institutions providing liquidity and credit enhancements could cause the fund to experience a loss and may effect its share price.

Municipal Securities Risk--The value of, payment of interest and repayment of principal with respect to, and the ability of the fund to sell, a municipal security may be affected by constitutional amendments, legislative enactments, executive orders, administrative regulations and voter initiatives as well as the economics of the regions in which the issuers in which the fund invests are located. Revenue bonds are generally not backed by the taxing power of the issuing municipality. To the extent that a municipal security in which the fund invests is not heavily followed by the investment community or such security issue is relatively small, the security may be difficult to value or sell at a fair price.

Concentration Risk--Because many municipal securities are issued to finance similar projects, especially those relating to education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal securities market and the fund. Moreover, sizeable investments in securities issued to finance similar projects could involve an increased risk to the fund if economic or other factors adversely affect the viability of these projects.

AIM TAX-EXEMPT CASH FUND

Foreign Credit Exposure Risk--U.S. dollar denominated securities which carry foreign credit exposure may be affected by unfavorable political, economic or governmental developments that could affect the repayment of principal or the payment of interest.

Derivatives Risk--The value of "derivatives" or "synthetics"--so-called because their value "derives" from the value of an underlying asset (including an underlying security), reference rate or index--may rise or fall more rapidly than other investments. For some derivatives, it is possible to lose more than the amount invested in the derivative. Derivatives may be used to create synthetic exposure to an underlying asset or to hedge portfolio risk. If the fund uses derivatives to "hedge" a portfolio risk, it is possible that the hedge may not succeed. This may happen for various reasons, including unexpected changes in the value of the rest of the fund's portfolio. Over the counter derivatives are also subject to counterparty risk, which is the risk that the other party to the contract will not fulfill its contractual obligation to complete the transaction with the fund.

Synthetic Municipal Securities Risk--The tax-exempt character of the interest paid on synthetic municipal securities is based on the tax-exempt income stream from the collateral. The Internal Revenue Service has not ruled on this issue and could deem income derived from synthetic municipal securities to be taxable.

Management Risk--There is no guarantee that the investment techniques and risk analyses used by the fund's portfolio manager(s) will produce the desired results.

OTHER INFORMATION

DIVIDENDS AND DISTRIBUTIONS

The fund expects that its distributions, if any, will consist primarily of income (most of which is expected to be exempt from federal income taxes).

DIVIDENDS

The fund generally declares dividends from net investment income on each business day and pays dividends, if any, monthly.

CAPITAL GAINS DISTRIBUTIONS

The fund generally distributes long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Because the fund is a money market fund, it does not anticipate realizing any long-term capital gains.

SPECIAL TAX INFORMATION REGARDING THE FUND

In addition to the general tax information set forth under the heading "General Information--Taxes" in this prospectus, the following information describes the tax impact of certain dividends you may receive from the fund:

- You will not be required to include the "exempt-interest" portion of dividends paid by the fund in your gross income for federal income tax purposes. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax return.

- The fund may invest a portion of its assets in securities that pay income that is not tax-exempt. The fund also may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of non- corporate shareholders.

- The fund may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for you, and may invest up to 20% of its net assets in such securities and other taxable securities. The fund will try to minimize investments that result in taxable dividends.

- Exempt-interest dividends from the fund are taken into account when determining the taxable portion of your social security or railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.

- The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the fund for the particular days in which you hold shares.

- From time to time, proposals have been introduced before Congress that would have the effect of reducing or eliminating the federal tax exemption on municipal securities. If such a proposal were enacted, the ability of the fund to pay exempt-interest dividends might be adversely affected.

THE AIM FUNDS

General Information

In addition to the fund, Invesco Aim serves as investment advisor to many other mutual funds that are offered to retail investors. The following information is about all the AIM funds that offer retail share classes.

CHOOSING A SHARE CLASS

Each of the funds offer multiple classes of shares. Each class represents an interest in the same portfolio of investments. Certain classes have higher expenses than other classes which may lower the return on your investment when compared to a less expensive class. In deciding which class of shares to purchase, you should consider the following attributes of the various share classes, among other things: (i) the eligibility requirements that apply to purchases of a particular class, (ii) the initial sales charges and contingent deferred sales charges (CDSCs), if any, applicable to the class, (iii) the 12b-1 fee, if any, paid by the class, and (iv) any services you may receive from a financial intermediary. Please contact your financial advisor to assist you in making your decision. Please refer to the prospectus fee table for more information on the fees and expenses of a particular fund's share classes.

(4) Class C shares of AIM Floating Rate Fund have a 12b-1 fee of 0.75%.

SHARE CLASS ELIGIBILITY

CLASS A, A3, B, C AND AIM CASH RESERVE SHARES

Class A, A3, B, C and AIM Cash Reserve Shares are available to all retail investors, including individuals, trusts, corporations and other business and charitable organizations and employee benefit plans. The share classes offer different fee structures which are intended to compensate financial intermediaries for services provided in connection with the sale of shares and continued maintenance of the customer relationship. You should consider the services provided by your financial advisor and any other intermediaries who will be involved in the servicing of your account when choosing a share class.

Class B shares are not available as an investment for retirement plans maintained pursuant to Section 401 of the Internal Revenue Code (the Code). These plans include 401(k) plans (including AIM Solo 401(k) plans), money purchase pension plans and profit sharing plans. However, plans that have existing accounts invested in Class B shares will continue to be allowed to make additional purchases.

CLASS P SHARES

In addition to the other share classes discussed herein, the AIM Summit Fund offers Class P shares, which were historically sold only through the AIM Summit Investors Plans I and II (each a Plan and, collectively, the Summit Plans). Class P shares are sold with no initial sales charge and have a 12b-1 fee of 0.10%. However, Class P shares are not sold to members of the general public. Only shareholders who had accounts in the Summit Plans at the close of business on December 8, 2006 may purchase Class P shares and only until the total of their combined investments in the Summit Plans and in Class P shares directly equals the face amount of their former Plan under the 30 year extended investment option. The face amount of a Plan is the combined total of all scheduled monthly investments under the Plan. For a Plan with a scheduled monthly investment of $100.00, the face amount would have been $36,000.00 under the 30 year extended investment option.

A-1

THE AIM FUNDS

CLASS R SHARES

Class R shares are generally available only to employee benefit plans. These may include, for example, retirement and deferred compensation plans maintained pursuant to Sections 401, 403, and 457 of the Code; nonqualified deferred compensation plans; health savings accounts maintained pursuant to Section 223 of the Code; and voluntary employees' beneficiary arrangements maintained pursuant to Section 501(c)(9) of the Code. Retirement plans maintained pursuant to Section 401 generally include 401(k) plans, profit sharing plans, money purchase pension plans, and defined benefit plans. Retirement plans maintained pursuant to Section 403 must be established and maintained by non-profit organizations operating pursuant to Section 501(c)(3) of the Code in order to purchase Class R shares. Class R shares are generally not available for individual retirement accounts (IRAs) such as traditional, Roth, SEP, SAR-SEP and SIMPLE IRAs.

INVESTOR CLASS SHARES

Some of the funds offer Investor Class shares. Investor Class shares are sold with no initial sales charge and have a maximum 12b-1 fee of 0.25%. Investor Class shares are not sold to members of the general public. Only the following persons may purchase Investor Class shares:

- Investors who established accounts prior to April 1, 2002, in Investor Class shares who have continuously maintained an account in Investor Class shares (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons). These investors are referred to as "grandfathered investors."

- Customers of certain financial intermediaries which have had relationships with the funds' distributor or any funds that offered Investor Class shares prior to April 1, 2002, who have continuously maintained such relationships. These intermediaries are referred to as "grandfathered intermediaries."

- Employee benefit plans; provided, however, that retirement plans maintained pursuant to Section 403 must be established and maintained by non-profit organizations operating pursuant to Section 501(c)(3) of the Code in order to purchase Investor Class shares, unless the plan is considered a grandfathered investor or the account is opened through a grandfathered intermediary. Investor Class shares are generally not available for IRAs, unless the IRA depositor is considered a grandfathered investor or the account is opened through a grandfathered intermediary.

- Any trustee, director, officer or employee of any fund or of Invesco Ltd. or any of its subsidiaries or affiliates, or any employee benefit plan maintained by any of them (this includes any immediate family members of such persons).

DISTRIBUTION AND SERVICE (12B-1) FEES

Except as noted below, each fund has adopted a distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a fund to pay distribution fees to Invesco Aim Distributors, Inc. (Invesco Aim Distributors) to compensate or reimburse, as applicable, Invesco Aim Distributors for its efforts in connection with the sale and distribution of the fund's shares and for services provided to shareholders, all or a substantial portion of which are paid to the dealer of record. Because the funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

The following funds and share classes do not have 12b-1 plans:

- AIM Tax-Free Intermediate Fund, Class A shares.

- AIM Money Market Fund, Investor Class shares.

- AIM Tax-Exempt Cash Fund, Investor Class shares.

- Premier Portfolio, Investor Class shares.

- Premier U.S. Government Money Portfolio, Investor Class shares.

- Premier Tax-Exempt Portfolio, Investor Class shares.

INITIAL SALES CHARGES (CLASS A SHARES ONLY)

The funds are grouped into four categories for determining initial sales charges. The "Other Information" section of each fund's prospectus will tell you the sales charge category in which the fund is classified. As used below, the term "offering price" with respect to all categories of Class A shares includes the initial sales charge.

CLASS A SHARES SOLD WITHOUT AN INITIAL SALES CHARGE

Certain categories of investors are permitted to purchase and certain intermediaries are permitted to sell Class A shares of the funds without an initial sales charge because their transactions involve little or no expense. The investors who are entitled to purchase Class A shares without paying an initial sales charge include the following:

- Any current or retired trustee, director, officer or employee of any fund or of Invesco Ltd. or any of its subsidiaries or affiliates, or any foundation, trust or employee benefit plan maintained by any of them (this includes any immediate family members of such persons).

- Any registered representative or employee of any intermediary who has an agreement with Invesco Aim Distributors to sell shares of the funds (this includes any immediate family members of such persons).

- Any investor who purchases their shares through an approved fee-based program (this may include any type of account for which there is some alternative arrangement made between the investor and the intermediary to provide for compensation of the intermediary for services rendered in connection with the sale of the shares and maintenance of the customer relationship).

- Any investor who purchases their shares with the proceeds of a rollover, transfer or distribution from a retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor to another retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor, to the extent that such proceeds are attributable to the redemption of shares of a fund held through the plan or account.

- Employee benefit plans; provided, however, that they meet at least one of the following requirements:

a. the plan has assets of at least $1 million;

b. there are at least 100 employees eligible to participate in the plan; or

c. all plan transactions are executed through a single omnibus account per fund; further provided that retirement plans maintained pursuant to Section 403(b) of the Code are not eligible to purchase shares without paying an initial sales charge based on the aggregate investment made by the plan or the number of eligible employees unless the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code.

- Any investor who maintains an account in Investor Class shares of a fund (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons).

- Qualified Tuition Programs created and maintained in accordance with
Section 529 of the Code.

- Insurance company separate accounts.

No investor will pay an initial sales charge in the following circumstances:

- When buying Class A shares of AIM Tax-Exempt Cash Fund and Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund.

- When reinvesting dividends and distributions.

- When exchanging shares of one fund, that were previously assessed a sales charge, for shares of another fund.

- As a result of a fund's merger, consolidation, or acquisition of the assets of another fund.

Additional information regarding eligibility to purchase shares at reduced or without sales charges is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

You may qualify for reduced sales charges or sales charge exceptions. To qualify for these reductions or exceptions, you or your financial advisor must notify the transfer agent at the time of purchase that your purchase qualifies for such treatment. Certain individuals and employer-sponsored retirement plans may link accounts for the purpose of qualifying for lower initial sales charges. You or your financial consultant must provide other account numbers to be considered for Rights of Accumulation, or mark the Letter of Intent section on the account application, or provide other relevant documentation, so that the transfer agent can verify your eligibility for the reduction or exception. Please consult the fund's Statement of Additional Information for details.

Purchases of Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund, AIM Cash Reserve Shares of AIM Money Market Fund and Investor Class shares of any fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to Rights of Accumulation or Letters of Intent.

A-3

THE AIM FUNDS

RIGHTS OF ACCUMULATION

You may combine your new purchases of Class A shares of a fund with other fund shares currently owned (Class A, B, C, P or R) and investments in the AIM College Savings Plan(R) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of your current purchase and the public offering price of all other shares you own. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates. There may be other accounts that are eligible to be linked, as described in the fund's Statement of Additional Information. However, if the accounts are not registered in the same name with the same taxpayer identification number, you will have to contact the transfer agent to request that those accounts be linked. The transfer agent will not be responsible for identifying all accounts that may be eligible to be linked.

LETTERS OF INTENT

Under a Letter of Intent (LOI), you commit to purchase a specified dollar amount of Class A shares of one or more funds during a 13-month period. The amount you agree to purchase determines the initial sales charge you pay. If the full amount committed to in the LOI is not invested by the end of the 13-month period, your account will be assessed the higher initial sales charge that would normally be applicable to the amount actually invested.

REINSTATEMENT FOLLOWING REDEMPTION

If you redeem shares of a fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B and P redemptions may be reinvested only into Class A shares with no initial sales charge. This reinstatement privilege does not apply to:

- A purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account, or

- A purchase paid for with proceeds from the redemption of shares that were held indirectly through an employee benefit plan.

In order to take advantage of this reinstatement privilege, you must inform your financial advisor or the transfer agent that you wish to do so at the time of your investment.

CONTINGENT DEFERRED SALES CHARGES (CDSCS)

CDSCS ON CLASS A SHARES AND AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND

You can purchase $1,000,000 or more (a Large Purchase) of Class A shares of Category I, II and IV funds without paying an initial sales charge. However, if you redeem these shares prior to 18 months after the date of purchase, they will be subject to a CDSC of 1%.

If you currently own Class A shares of a Category I, II or IV fund, and make additional purchases without paying an initial sales charge that result in account balances of $1,000,000 or more, the additional shares purchased will be subject to an 18-month, 1% CDSC.

If Invesco Aim Distributors pays a concession to the dealer of record in connection with a Large Purchase of Class A shares by an employee benefit plan, the Class A shares may be subject to a 1% CDSC if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

If you acquire AIM Cash Reserve Shares of AIM Money Market Fund, Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.

CDSCS ON CLASS B SHARES AND ON CLASS C SHARES OF FUNDS OTHER THAN AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class B and Class C shares are sold without an initial sales charge. However, they are subject to a CDSC. If you redeem your shares during the CDSC period, you will be assessed a CDSC as follows, unless you qualify for one of the CDSC exceptions outlined below:

YEAR SINCE PURCHASE MADE:   CLASS B   CLASS C
-------------------------   -------   -------
First                           5%         1%
Second                          4       None
Third                           3       None

Fourth                          3      None
Fifth                           2      None
Sixth                           1      None
Seventh and following        None      None

CDSCS ON CLASS C SHARES -- EMPLOYEE BENEFIT PLAN

Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class C shares by an employee benefit plan; the Class C shares are subject to a 1.00% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

CDSCS ON CLASS C SHARES OF AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class C shares of AIM LIBOR Alpha Fund and AIM Short Term Bond Fund are not normally subject to a CDSC. However, if you acquired shares of those funds through an exchange, and the shares originally purchased were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC. Conversely, if you acquire Class C shares of any other fund as a result of an exchange involving Class C shares of

A-4

THE AIM FUNDS

AIM LIBOR Alpha Fund or AIM Short Term Bond Fund that were not subject to a CDSC, then the shares acquired as a result of the exchange will not be subject to a CDSC.

CDSCS ON CLASS R SHARES

Class R shares are not normally subject to a CDSC. However, if Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class R shares by an employee benefit plan, the Class R shares are subject to a 0.75% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

COMPUTING A CDSC

The CDSC on redemptions of shares is computed based on the lower of their original purchase price or current net asset value, net of reinvested dividends and capital gains distributions. In determining whether to charge a CDSC, shares are accounted for on a first-in, first-out basis, which means that you will redeem shares on which there is no CDSC first and, then, shares in the order of their purchase.

CDSC EXCEPTIONS

Investors who own shares that are otherwise subject to a CDSC will not pay a CDSC in the following circumstances:

- If you participate in the Systematic Redemption Plan and withdraw up to 12% of the value of your shares that are subject to a CDSC in any twelve-month period.

- If you redeem shares to pay account fees.

- If you are the executor, administrator or beneficiary of an estate or are otherwise entitled to assets remaining in an account following the death or post-purchase disability of a shareholder or beneficial owner and you choose to redeem those shares.

There are other circumstances under which you may be able to redeem shares without paying CDSCs. Additional information regarding CDSC exceptions is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

Shares acquired through the reinvestment of dividends and distributions are not subject to CDSCs.

The following share classes are sold with no CDSC:

- Class A shares of any Category III Fund.

- Class A shares of AIM Tax-Exempt Cash Fund.

- Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund.

- AIM Cash Reserve Shares of AIM Money Market Fund.

- Investor Class shares of any fund.

- Class P shares of AIM Summit Fund.

REDEMPTION FEES

Certain funds impose a 2% redemption fee (on redemption proceeds) if you redeem or exchange shares within 31 days of purchase. Please refer to the applicable fund's prospectus to determine whether that fund imposes a redemption fee. As of the date of this prospectus, the following funds impose redemption fees:

AIM Asia Pacific Growth Fund
AIM China Fund
AIM Developing Markets Fund

The redemption fee will be retained by the fund from which you are redeeming or exchanging shares, and is intended to offset the trading costs, market impact and other costs associated with short-term money movements in and out of the fund. The redemption fee is imposed on a first-in, first-out basis, which means that you will redeem shares in the order of their purchase.

A-5

THE AIM FUNDS

Redemption fees generally will not be charged in the following circumstances:

- Redemptions and exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to assess the redemption fees.

- Redemptions and exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, variable insurance contracts or separately managed qualified default investment alternative vehicles maintained pursuant to Section 404(c)(5) of the Employee Retirement Income Security Act of 1974, as amended (ERISA), which use the funds as underlying investments.

- Redemptions and exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs or systematic withdrawal plans.

- Redemptions requested within 31 days following the death or post-purchase disability of an account owner.

- Redemptions or exchanges initiated by a fund.

The following shares are not subject to redemption fees, irrespective of whether they are redeemed in accordance with any of the exceptions set forth above:

- Shares acquired through the reinvestment of dividends and distributions.

- Shares acquired through systematic purchase plans.

- Shares acquired in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan to the trustee or custodian of another employee benefit plan.

Shares held by employee benefit plans will only be subject to redemption fees if the shares were acquired by exchange and are redeemed by exchange within 31 days of purchase.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

The funds have the discretion to waive the 2% redemption fee if a fund is in jeopardy of losing its registered investment company qualification for tax purposes.

Your financial advisor or other intermediary may charge service fees for handling redemption transactions. Your shares also may be subject to a CDSC in addition to the redemption fee.

PURCHASING SHARES

If you hold your shares through a financial advisor or other intermediary, your eligibility to purchase shares and the terms by which you may purchase, redeem and exchange shares may differ depending on that institution's policies.

Purchase orders will not be processed unless the account application and purchase payment are received in good order. In accordance with the USA PATRIOT Act, if you fail to provide all the required information requested in the current account application, your purchase order will not be processed. Additionally, federal law requires that the fund verify and record your identifying information.

SYSTEMATIC PURCHASE PLAN

You can arrange for periodic investments in any of the funds by authorizing the transfer agent to withdraw the amount of your investment from your bank account on a day or dates you specify and in an amount of at least $50 per fund. You may stop the Systematic Purchase Plan at any time by giving the transfer agent notice ten days prior to your next scheduled withdrawal. Certain financial advisors and other intermediaries may also offer systematic purchase plans.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic periodic exchanges, if permitted, from one fund to another fund or multiple other funds. The account from which exchanges are to be made must have a minimum balance of $5,000 before you can use this option. Exchanges will occur on (or about) the day of the month you specify, in the amount you specify. Dollar Cost Averaging cannot be set up for the 29th through the 31st of the month. The minimum amount you can exchange to another fund is $50. Certain financial advisors and other intermediaries may also offer dollar cost averaging programs. If you participate in one of these programs and it is the same or similar to Invesco Aim's Dollar Cost Averaging program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

AUTOMATIC DIVIDEND AND DISTRIBUTION INVESTMENT

Your dividends and distributions may be paid in cash or reinvested in the same fund or another fund without paying an initial sales charge. Unless you specify otherwise, your dividends and distributions will automatically be reinvested in the same fund. If you elect to receive your distributions by check, and the distribution amount is $10 or less, then the amount will be automatically reinvested in the same fund and no check will be issued. If you have elected to receive distributions by check, and the postal service is unable to deliver checks to your address of record, then your distribution election may be converted to having all subsequent distributions reinvested in the same fund and no checks will be issued. You should contact the transfer agent to change your distribution option, and your request to do so must be received by the transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

You must comply with the following requirements to be eligible to invest your dividends and distributions in shares of another fund:

- Your account balance in the fund paying the dividend or distribution must be at least $5,000; and

- Your account balance in the fund receiving the dividend or distribution must be at least $500.

PORTFOLIO REBALANCING PROGRAM

If you have at least $5,000 in your account, you may participate in the Portfolio Rebalancing Program. Under this Program, you can designate how the total value of your fund holdings should be rebalanced, on a percentage basis, between two and ten of your funds on a quarterly, semiannual or annual basis. Your portfolio will be rebalanced through the exchange of shares in one or more of your funds for shares of the same class of one or more other funds in your portfolio. Rebalancing will not occur if your portfolio is within 2% of your stated allocation. If you wish to participate in the Program, make changes or cancel the Program, the transfer agent must receive your request to participate, changes, or cancellation in good order at least five business days prior to the next rebalancing date, which is normally the 28th day of the last month of the period you choose. We may modify, suspend or terminate the Program at any time on 60 days' prior written notice to participating investors. Certain financial advisors and other intermediaries may also offer portfolio rebalancing programs. If you participate in one of these programs and it is the same as or similar to Invesco Aim's program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

RETIREMENT PLANS SPONSORED BY INVESCO AIM DISTRIBUTORS

Invesco Aim Distributors acts as the prototype sponsor for certain types of retirement plan documents. These plan documents are generally available to anyone wishing to invest plan assets in the funds. These documents are provided subject to terms, conditions and fees that vary by plan type. Contact your financial advisor or other intermediary for details.

REDEEMING SHARES

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call during the hours of the customary trading session of the New York Stock Exchange (NYSE) in order to effect the redemption at that day's net asset value. For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call before the last net asset value determination in order to effect the redemption that day.

A-8

THE AIM FUNDS

TIMING AND METHOD OF PAYMENT

We normally will send out payments within one business day, and in any event no more than seven days, after your redemption request is received in good order (meaning that all necessary information and documentation related to the redemption request have been provided to the transfer agent). If you redeem shares recently purchased by check or ACH, you may be required to wait up to ten business days before we send your redemption proceeds. This delay is necessary to ensure that the purchase has cleared. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted on the NYSE.

Redemption checks are mailed to your address of record, via first class U.S. mail, unless you make other arrangements with the transfer agent.

We use reasonable procedures to confirm that instructions communicated via telephone and the Internet are genuine, and we are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

EXPEDITED REDEMPTIONS (AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND ONLY)

If you place your redemption order by telephone, before 11:30 a.m. Eastern Time and request an expedited redemption, we will transmit payment of redemption proceeds on that same day via federal wire to a bank of record on your account. If we receive your redemption order after 11:30 a.m. Eastern Time and before the close of the customary trading session of the NYSE, we will transmit payment on the next business day.

SYSTEMATIC WITHDRAWALS

You may arrange for regular periodic withdrawals from your account in amounts equal to or greater than $50 per fund. We will redeem the appropriate number of shares from your account to provide redemption proceeds in the amount requested. You must have a total account balance of at least $5,000 in order to establish a Systematic Redemption Plan, unless you are establishing a Required Minimum Distribution for a retirement plan. You can stop this plan at any time by giving ten days prior notice to the transfer agent.

CHECK WRITING

The transfer agent provides check writing privileges for accounts in the following funds and share classes:

- AIM Money Market Fund, AIM Cash Reserve Shares and Investor Class shares

- AIM Tax-Exempt Cash Fund, Class A shares and Investor Class shares

- Premier Portfolio, Investor Class shares

- Premier Tax-Exempt Portfolio, Investor Class shares

- Premier U.S. Government Money Portfolio, Investor Class shares

You may redeem shares of these funds by writing checks in amounts of $250 or more if you have completed an authorization form. Redemption by check is not available for retirement accounts. Checks are not eligible to be converted to ACH by the payee. You may not give authorization to a payee by phone to debit your account by ACH for a debt owed to the payee.

SIGNATURE GUARANTEES

We require a signature guarantee in the following circumstances:

- When your redemption proceeds will equal or exceed $250,000 per fund.

- When you request that redemption proceeds be paid to someone other than the registered owner of the account.

- When you request that redemption proceeds be sent somewhere other than the address of record or bank of record on the account.

- When you request that redemption proceeds be sent to a new address or an address that changed in the last 30 days.

The transfer agent will accept a guarantee of your signature by a number of different types of financial institutions. Call the transfer agent for additional information. Some institutions have transaction amount maximums for these guarantees. Please check with the guarantor institution to determine whether the signature guarantee offered will be sufficient to cover the value of your transaction request.

REDEMPTIONS IN KIND

Although the funds generally intend to pay redemption proceeds solely in cash, the funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind).

REDEMPTIONS INITIATED BY THE FUNDS

If your account (Class A, A3, B, C, P and Investor Class shares only) has been open at least one year, you have not made an additional purchase in the account during the past six calendar months, and the value of your account falls below $500 for three consecutive months, the funds have the right to redeem the account after giving you 60 days' prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to $500 or by initiating a Systematic Purchase Plan.

If the fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the fund is not able to verify your identity as required by law, the fund may, at its discretion, redeem the account and distribute the proceeds to you.

EXCHANGING SHARES

You may, under certain circumstances, exchange shares in one fund for those of another fund. An exchange is the purchase of shares in one fund which

A-9

THE AIM FUNDS

is paid for with the proceeds from a redemption of shares of another fund effectuated on the same day. Accordingly, the procedures and processes applicable to redemptions of fund shares, as discussed under the heading "Redeeming Shares" above, will apply. Before requesting an exchange, review the prospectus of the fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the funds. If you wish to exchange shares of one fund for those of another fund, you must consult the prospectus of the fund whose shares you wish to acquire to determine whether the fund is offering shares to new investors and whether you are eligible to acquire shares of that fund.

PERMITTED EXCHANGES

Except as otherwise provided below under "Exchanges Not Permitted", you generally may exchange your shares for shares of the same class of another fund. The following below shows permitted exchanges:

- Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested; and

- If you have physical share certificates, you must return them to the transfer agent in order to effect the exchange.

Under unusual market conditions, a fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares. Any of the participating funds or the distributor may modify or terminate this privilege at any time.

LIMIT ON THE NUMBER OF EXCHANGES

You will generally be limited to four exchanges out of a fund per calendar year (other than the money market funds); provided, however, that the following transactions will not count toward the exchange limitation:

- Exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to apply the exchange limitation.

- Exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, and insurance company separate accounts which use the funds as underlying investments.

- Generally, exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs.

- Exchanges initiated by a fund or by the trustee, administrator or other fiduciary of an employee benefit plan (not in response to distribution or exchange instructions received from a plan participant).

Each fund reserves the discretion to accept exchanges in excess of these guidelines on a case-by-case basis if the fund, or its designated agent, believes that granting such exceptions would be consistent with the best interests of shareholders.

There is no limit on the number of exchanges out of AIM Limited Maturity Treasury Fund, AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio.

If you exchange shares of one fund for shares of multiple other funds as part of a single transaction, that transaction is counted as one exchange out of a fund.

INITIAL SALES CHARGES AND CDSCS APPLICABLE TO EXCHANGES

You may be required to pay an initial sales charge when exchanging from a fund with a lower initial sales charge than the one into which you are exchanging. If you exchange into shares that are subject to a CDSC, we will begin the holding period for purposes of calculating the CDSC on the date

you made your initial purchase.

RIGHTS RESERVED BY THE FUNDS

Each fund and its agents reserve the right at any time to:

- Reject or cancel all or any part of any purchase or exchange order.

- Modify any terms or conditions related to the purchase, redemption or exchange of shares of any fund.

- Reject or cancel any request to establish a Systematic Purchase Plan, Systematic Redemption Plan or Portfolio Rebalancing Program.

- Suspend, change or withdraw all or any part of the offering made by this prospectus.

PRICING OF SHARES

DETERMINATION OF NET ASSET VALUE

The price of each fund's shares is the fund's net asset value per share. The funds value portfolio securities for which market quotations are readily available at market value. The funds value all other securities and assets for which market quotations are unavailable or unreliable at their fair value in good faith using procedures approved by the Boards of Trustees of the funds (collectively, the Board). The Board has delegated the daily determination of good faith fair value methodologies to Invesco Aim's Valuation Committee, which acts in accordance with Board approved policies. On a quarterly basis, Invesco Aim provides the Board various reports indicating the quality and effectiveness of its fair value decisions on portfolio holdings. Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day.

Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the NYSE and when the fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events which affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where market quotations are not readily available, including where Invesco Aim determines that the closing price of the security is unreliable, Invesco Aim will value the security at fair value in good faith using procedures approved by the Board. Fair value pricing may reduce the ability of frequent traders to take advantage of arbitrage opportunities resulting from potentially "stale" prices of portfolio holdings. However, it cannot eliminate the possibility of frequent trading.

Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. Fair value requires consideration of all appropriate factors, including indications of fair value available from pricing services. A fair value price is an estimated price and may vary from the prices used by other mutual funds to calculate their net asset values.

Invesco Aim may use indications of fair value from pricing services approved by the Board. In other circumstances, the Invesco Aim Valuation Committee may fair value securities in good faith using procedures approved by the Board. As a means of evaluating its fair value process, Invesco Aim routinely compares closing market prices, the next day's opening prices for the security in its primary market if available, and indications of fair value from other sources. Fair value pricing methods and pricing services can change from time to time as approved by the Board.

Specific types of securities are valued as follows:

Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.

Domestic Exchange Traded Equity Securities. Market quotations are generally available and reliable for domestic exchange traded equity securities. If market quotations are not available or are unreliable, Invesco Aim will value the security at fair value in good faith using procedures approved by the Board.

Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the fund may fair value the security. If an issuer specific event has occurred that Invesco Aim determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. Invesco Aim also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where Invesco Aim believes, at the approved degree of certainty, that the price is not reflective of current market value, Invesco Aim will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time.

Fund securities primarily traded on foreign markets may trade on days that are not business days of the fund. Because the net asset value of fund shares is determined only on business days of the fund, the value of the portfolio securities of a fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the fund.

Fixed Income Securities. Government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined

A-11

THE AIM FUNDS

without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Invesco Aim valuation committee will fair value the security using procedures approved by the Board.

Short-term Securities. The funds' short-term investments are valued at amortized cost when the security has 60 days or less to maturity. AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio value all their securities at amortized cost. AIM High Income Municipal Fund, AIM Municipal Bond Fund and AIM Tax-Free Intermediate Fund value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.

Futures and Options. Futures contracts are valued at the final settlement price set by the exchange on which they are principally traded. Options are valued on the basis of market quotations, if available.

Swap Agreements. Swap Agreements are fair valued using an evaluated quote provided by an independent pricing service. Evaluated quotes provided by the pricing service are based on a model that may include end of day net present values, spreads, ratings, industry and company performance.

Open-end Funds. To the extent a fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing fund will calculate its net asset value using the net asset value of the underlying fund in which it invests.

Each fund determines the net asset value of its shares on each day the NYSE is open for business (a business day), as of the close of the customary trading session, or earlier NYSE closing time that day. AIM Money Market Fund also determines its net asset value as of 12:00 noon Eastern Time on each business day. Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio determine the net asset value of their shares every fifteen minutes on each business day, beginning at 8:00 a.m. Eastern Time. The last net asset value determination on any business day for Premier Portfolio and Premier U.S. Government Money Portfolio will generally occur at 5:30 p.m. Eastern Time, and the last net asset value determination on any business day for Premier Tax-Exempt Portfolio will generally occur at 4:30 p.m. Eastern Time. Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio are authorized not to open for trading on a day that is otherwise a business day if the Federal Reserve Bank of New York and the Bank of New York, the fund's custodian, are not open for business or the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading and any such day will not be considered a business day. Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio also may close early on a business day if SIFMA recommends that government securities dealers close early. If Premier Portfolio, Premier Tax-Exempt Portfolio or Premier U.S. Government Money Portfolio uses its discretion to close early on a business day, the last net asset value calculation will occur as of the time of such closing.

From time to time and in circumstances deemed appropriate by Invesco Aim in its sole discretion, each of Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio may remain open for business, during customary business day hours, on a day that the NYSE is closed for business. In such event, on such day you will be permitted to purchase or redeem shares of such funds and net asset values will be calculated for such funds.

TIMING OF ORDERS

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, you can purchase or redeem shares on each business day prior to the close of the customary trading session or any earlier NYSE closing time that day. For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, purchase orders that are received and accepted before the close of the customary trading session or any earlier NYSE closing time on a business day generally are processed that day and settled on the next business day.

For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, you can purchase or redeem shares on each business day, prior to the last net asset value determination on such business day; however, if your order is received and accepted after the close of the customary trading session or any earlier NYSE closing time that day, your order generally will be processed on the next business day and settled on the second business day following the receipt and acceptance of your order.

For all funds, you can exchange shares on each business day, prior to the close of the customary trading session or any earlier NYSE closing time that day. Shareholders of Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio therefore cannot exchange their shares after the close of the customary trading session or any earlier NYSE closing time on a particular day, even though these funds remain open after such closing time.

The funds price purchase, exchange and redemption orders at the net asset value calculated after the transfer agent receives an order in good order. Any applicable sales charges are applied at the time an order is processed. A fund may postpone the right of redemption only under unusual circumstances, as allowed by the Securities and Exchange Commission, such as when the NYSE restricts or suspends trading.

TAXES

In general, if you are a taxable investor, dividends and distributions you receive are taxable as ordinary income or long-term capital gains for federal income tax purposes. This is true whether you reinvest distributions in additional fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from each fund during the prior year. Investors in tax-exempt funds should read the information under the heading "Other Information--Special Tax Information Regarding the Fund" in the applicable fund's prospectus. In addition, investors in taxable accounts should be aware of the following basic tax points:

A-12

THE AIM FUNDS

- Distributions of net short-term capital gains are taxable to you as ordinary income. A fund that is expected to have higher turnover than that of other funds is more likely to generate short-term gain or loss.

- Distributions of net long-term capital gains are taxable to you as long-term capital gains no matter how long you have owned your fund shares.

- If you are an individual and meet certain holding period requirements, a portion of income dividends paid by a fund may be designated as qualified dividend income eligible for taxation at long-term capital gain rates. These reduced rates generally are available for dividends paid by a fund out of dividends earned on the fund's investment in stocks of domestic corporations and qualified foreign corporations.

- Distributions declared to shareholders with a record date in December--if paid to you by the end of January--are taxable for federal income tax purposes as if received in December.

- Any long-term or short-term capital gains realized from redemptions of fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another fund is the same as a sale.

- If you invest in a fund shortly before it makes a capital gains distribution, the distribution will lower the value of the fund's shares by the amount of the distribution and, in effect, you will receive some of your investment back in the form of a taxable distribution. This is sometimes referred to as "buying a dividend."

- By law, if you do not provide a fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A fund also must withhold if the IRS instructs it to do so. When withholding is required, the amount will be 28% of any distributions or proceeds paid.

- Fund distributions and gains from sale or exchange of your fund shares generally are subject to state and local income taxes.

- Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits and estate taxes may apply to an investment in a fund.

The preceding discussion concerning the taxability of fund dividends and distributions and of redemptions and exchanges of fund shares is inapplicable to investors that are generally exempt from federal income tax, such as retirement plans that are qualified under Section 401, 403, 408, 408A and 457 of the Code, individual retirement accounts (IRAs) and Roth IRAs. You should consult your tax advisor before investing in a fund.

PAYMENTS TO FINANCIAL ADVISORS

The financial advisor or intermediary through which you purchase your shares may receive all or a portion of the sales charges and distribution fees discussed above. In addition to those payments, Invesco Aim Distributors or one or more of its corporate affiliates (collectively, Invesco Aim Affiliates) may make additional cash payments to financial advisors in connection with the promotion and sale of shares of the funds. These additional cash payments may include cash payments and other payments for certain marketing and support services. Invesco Aim Affiliates make these payments from their own resources, from Invesco Aim Distributors' retention of initial sales charges and from payments to Invesco Aim Distributors made by the funds under their 12b-1 plans. In this context, "financial advisors" include any broker, dealer, bank (including bank trust departments), registered investment advisor, financial planner, retirement plan administrator and any other financial intermediary having a selling, administration or similar agreement with Invesco Aim Affiliates.

Invesco Aim Affiliates make payments as incentives to certain financial advisors to promote and sell shares of the funds. The benefits Invesco Aim Affiliates receive when they make these payments include, among other things, placing the funds on the financial advisor's funds sales system, and access (in some cases on a preferential basis over other competitors) to individual members of the financial advisor's sales force or to the financial advisor's management. These payments are sometimes referred to as "shelf space" payments because the payments compensate the financial advisor for including the funds in its fund sales system (on its "sales shelf"). Invesco Aim Affiliates compensate financial advisors differently depending typically on the level and/or type of considerations provided by the financial advisor. The payments Invesco Aim Affiliates make may be calculated based on sales of shares of the funds (Sales-Based Payments), in which case the total amount of such payments shall not exceed 0.25% of the public offering price of all shares sold by the financial advisor during the particular period. Payments may also be calculated based on the average daily net assets of the applicable funds attributable to that particular financial advisor (Asset-Based Payments), in which case the total amount of such cash payments shall not exceed 0.25% per annum of those assets during a defined period. Sales-Based Payments primarily create incentives to make new sales of shares of the funds and Asset-Based Payments primarily create incentives to retain previously sold shares of the funds in investor accounts. Invesco Aim Affiliates may pay a financial advisor either or both Sales-Based Payments and Asset-Based Payments.

Invesco Aim Affiliates are motivated to make these payments as they promote the sale of fund shares and the retention of those investments by clients of financial advisors. To the extent financial advisors sell more shares of the funds or retain shares of the funds in their clients' accounts, Invesco Aim Affiliates benefit from the incremental management and other fees paid to Invesco Aim Affiliates by the funds with respect to those assets.

Invesco Aim Affiliates also may make payments to certain financial advisors for certain administrative services, including record keeping and sub-accounting of shareholder accounts pursuant to a sub-transfer agency, omnibus account service or sub-accounting agreement. All fees payable by Invesco Aim Affiliates under this category of services are charged back to the funds, subject to certain limitations approved by the Board.

You can find further details in the fund's Statement of Additional Information about these payments and the services provided by financial advisors. In certain cases these payments could be significant to the financial advisor. Your financial advisor may charge you additional fees or commissions other than those disclosed in this prospectus. You can ask your financial advisor about any payments it receives from Invesco Aim Affiliates or the funds, as well as about fees and/or commissions it charges.

EXCESSIVE SHORT-TERM TRADING ACTIVITY (MARKET TIMING) DISCLOSURES

While the funds provide their shareholders with daily liquidity, their investment programs are designed to serve long-term investors and are not designed to accommodate excessive short-term trading activity in violation of our policies described below. Excessive short-term trading activity in the funds' shares (i.e., a purchase of fund shares followed shortly thereafter by a redemption of such shares, or vice versa) may hurt the long-term performance of certain funds by requiring them to maintain an excessive amount of cash or to liquidate portfolio holdings at a disadvantageous time, thus interfering with the efficient management of such funds by causing them to incur increased brokerage and administrative costs. Where excessive short-term trading activity seeks to take advantage of arbitrage opportunities from stale prices for portfolio securities, the value of fund shares held by long-term investors may be diluted. The Board has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares for all funds except the money market funds. However, there is the risk that these funds' policies and procedures will prove ineffective in whole or in part to detect or prevent excessive or short-term trading. These funds may alter their policies at any time without prior notice to shareholders if the advisor believes the change would be in the best interests of long-term shareholders.

The Invesco Aim Affiliates currently use the following tools designed to discourage excessive short-term trading in the retail funds:

- Trade activity monitoring.

- Trading guidelines.

- Redemption fees on trades in certain funds.

- The use of fair value pricing consistent with procedures approved by the Board.

Each of these tools is described in more detail below. Although these tools are designed to discourage excessive short-term trading, you should understand that none of these tools alone nor all of them taken together eliminate the possibility that excessive short-term trading activity in the funds will occur. Moreover, each of these tools involves judgments that are inherently subjective. Invesco Aim Affiliates seek to make these judgments to the best of their abilities in a manner that they believe is consistent with long-term shareholder interests.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

Money Market Funds. The Board of AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio (the money market funds) have not adopted any policies and procedures that would limit frequent purchases and redemptions of such funds' shares. The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions, and determined that those risks were minimal. Nonetheless, to the extent that a money market fund must maintain additional cash and/or securities with short-term durations in greater amounts than may otherwise be required or borrow to honor redemption requests, the money market fund's yield could be negatively impacted.

The Board does not believe that it is appropriate to adopt any such policies and procedures for the money market funds for the following reasons:

- The money market funds are offered to investors as cash management vehicles; investors must perceive an investment in such funds as an alternative to cash, and must be able to purchase and redeem shares regularly and frequently.

- One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of the money market funds will be detrimental to the continuing operations of such funds.

- The money market funds' portfolio securities are valued on the basis of amortized cost, and such funds seek to maintain a constant net asset value. As a result, there are no price arbitrage opportunities.

- Because the money market funds seek to maintain a constant net asset value, investors expect to receive upon redemption the amount they originally invested in such funds. Imposition of redemption fees would run contrary to investor expectations.

AIM Limited Maturity Treasury Fund. The Board of AIM Limited Maturity Treasury Fund has not adopted any policies and procedures that would limit frequent purchases and redemptions of such fund's shares. The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions and determined that those risks were minimal. Nonetheless, to the extent that AIM Limited Maturity Treasury Fund must maintain additional cash and/or securities with short-term durations in greater amounts than may otherwise be required or borrow to honor redemption requests, AIM Limited Maturity Treasury Fund's yield could be negatively impacted.

The Board does not believe that it is appropriate to adopt any such policies and procedures for the fund for the following reasons:

A-14

THE AIM FUNDS

- Many investors use AIM Limited Maturity Treasury Fund as a short-term investment alternative and should be able to purchase and redeem shares regularly and frequently.

- One of the advantages of AIM Limited Maturity Treasury Fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of AIM Limited Maturity Treasury Fund will be detrimental to the continuing operations of such fund.

TRADE ACTIVITY MONITORING
Invesco Aim Affiliates monitor selected trades on a daily basis in an effort to detect excessive short-term trading activities. If, as a result of this monitoring, Invesco Aim Affiliates believe that a shareholder has engaged in excessive short-term trading, they will seek to act in a manner that they believe is consistent with the best interests of long-term investors, which may include taking steps such as (i) asking the shareholder to take action to stop such activities or (ii) refusing to process future purchases or exchanges related to such activities in the shareholder's accounts other than exchanges into a money market fund. Invesco Aim Affiliates will use reasonable efforts to apply the fund's policies uniformly given the practical limitations described above.

The ability of Invesco Aim Affiliates to monitor trades that are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent.

TRADING GUIDELINES

If you exceed four exchanges out of a fund per calendar year (other than the money market funds and AIM Limited Maturity Treasury Fund), or a fund or an Invesco Aim Affiliate determines, in its sole discretion, that your short-term trading activity is excessive (regardless of whether or not you exceed such guidelines), it may, in its discretion, reject any additional purchase and exchange orders.

The ability of Invesco Aim Affiliates to monitor exchanges made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent. If shares of the funds are held in the name of a conduit investment vehicle and not in the names of the individual investors who have invested in the funds through the conduit investment vehicle, the conduit investment vehicle may be considered an individual shareholder of the funds. To the extent that a conduit investment vehicle is considered an individual shareholder of the funds, the funds are likely to be limited in their ability to impose exchange limitations on individual transactions initiated by investors who have invested in the funds through the conduit investment vehicle.

REDEMPTION FEES

You may be charged a 2% redemption fee if you redeem, including redeeming by exchange, shares of certain funds within 31 days of purchase. The ability of a fund to assess a redemption fee on redemptions effectuated through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent.

FAIR VALUE PRICING

Securities owned by a fund are to be valued at current market value if market quotations are readily available. All other securities and assets of a fund for which market quotations are not readily available are to be valued at fair value determined in good faith using procedures approved by the Board. Fair value pricing may reduce the ability of frequent traders to take advantage of arbitrage opportunities resulting from potentially "stale" prices of portfolio holdings. However, it cannot eliminate the possibility of frequent trading.

AIM TAX-FREE INTERMEDIATE FUND

RISK/RETURN SUMMARY

INVESTMENT OBJECTIVE

The fund's investment objective is to generate as high a level of tax-exempt income as is consistent with preservation of capital.

PRIMARY INVESTMENT STRATEGIES

The fund will invest, normally, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in municipal debt securities that (1) pay interest that is excluded from gross income for federal income tax purposes, and (2) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. At the present time, the fund will not invest in municipal debt securities if the interest on such securities is subject to the federal alternative minimum tax.

The fund intends to invest at least 80% of its assets in municipal debt securities determined to be of investment grade quality. Up to 20% of the fund's assets may be invested in municipal debt securities that are determined to be below investment grade quality. These types of securities are commonly known as "junk bonds."

In selecting securities for the fund's portfolio, the portfolio managers focus on municipal securities they believe have favorable prospects for high current income.

The portfolio managers seek to maintain a dollar-weighted average portfolio maturity for the fund of between three and ten years.

Please see "Investment Objective, Strategies and Risks" for additional information regarding the fund's investment strategies.

PRINCIPAL RISKS

Among the principal risks of investing in the fund, which could adversely affect its net asset value, yield and total return are:

Market Risk           High Yield Risk              Concentration Risk                     Leverage Risk
Interest Rate Risk    Reinvestment Risk            Derivatives Risk                       Management Risk
Credit Risk           Municipal Securities Risk    Synthetic Municipal Securities Risk

Please see "Investment Objective, Strategies and Risks" for a description of these risks.

There is a risk that you could lose all or a portion of your investment in the fund and that the income you may receive from your investment may vary. The value of your investment in the fund will rise and fall with the prices of the securities in which the fund invests.

An investment in the fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.

PERFORMANCE TABLE
The following performance table compares the fund's performance to that of a broad-based securities market index, a style specific index and a peer group index. The fund's performance reflects payment of sales loads, if applicable. The indices may not reflect payment of fees, expenses or taxes. The fund is not managed to track the performance of any particular index, including the indices shown below, and consequently, the performance of the fund may deviate significantly from the performance of the indices shown below.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown for Class A only and after-tax returns for Class A3 will vary.

(1) The returns shown for the one year and five year periods are the historical performance of the fund's Class A3 shares. The return shown for the ten year period is the blended return of the historical performance of the fund's Class A3 shares since their inception and the restated historical performance of the fund's Class A shares (for the periods prior to the inception of the Class A3 shares) at net asset value, adjusted to reflect the Rule 12b-1 fees applicable to Class A3 shares. The inception date shown in the table is that of the fund's Class A shares. The inception date of the fund's Class A3 shares is October 31, 2002.
(2) The Lehman Brothers Municipal Bond Index covers municipal bonds with a minimum credit rating of Baa, an outstanding par value of at least $5 million and issued as a part of a transaction of at least $50 million USD. The bonds must have been issued after December 31, 1990, and have a remaining maturity of at least one year. The fund has also included the Merrill Lynch 3-7 Year Municipal Index, which the fund believes more closely reflects the performance of the types of securities in which the fund invests. In addition, the Lipper Intermediate Municipal Debt Funds Index (which may or may not include the fund) is included for comparison to a peer group.
(3) The Merrill Lynch 3-7 Year Municipal Index is a domestic bond index that holds municipal bonds with maturities that range between three and seven years.
(4) The Lipper Intermediate Municipal Debt Funds Index is an equally weighted representation of the largest funds in the Lipper Intermediate Municipal Debt Funds category. These funds invest in municipal debt issues with dollar-weighted average maturities of five to ten years.

(1) There is no guarantee that actual expenses will be the same as those shown in the table.

EXPENSE EXAMPLE
This example is intended to help you compare the cost of investing in different classes the fund with the cost of investing in other mutual funds.

The expense example assumes you:
(i) invest $10,000 in the fund for the time periods indicated;
(ii) redeem all of your shares at the end of the periods indicated;
(iii) earn a 5% return on your investment before operating expenses each year;

(iv) incur the same amount in operating expenses each year (after giving effect to any applicable contractual fee waivers and/or expense reimbursements); and

(v) incur applicable initial sales charges (see "General Information--Choosing a Share Class" section of this prospectus for applicability of initial sales charge).

To the extent fees are waived and/or expenses are reimbursed voluntarily, your expenses will be lower. Although your actual returns and costs may be higher or lower, based on these assumptions your costs would be:

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The settlement agreement between Invesco Aim Advisors, Inc. and certain of its affiliates and the New York Attorney General requires Invesco Aim Advisors, Inc. and certain of its affiliates to provide certain hypothetical information regarding investment and expense information. The chart below is intended to reflect the annual and cumulative impact of the fund's expenses, including investment advisory fees and other fund costs, on the fund's return over a 10- year period. The example reflects the following:
- You invest $10,000 in the fund and hold it for the entire 10 year period;
- Your investment has a 5% return before expenses each year;
- Hypotheticals both with and without any applicable initial sales charge applied (see "General Information -- Choosing a Share Class" section of this prospectus for applicability of initial sales charge); and
- There is no sales charge on reinvested dividends.

There is no assurance that the annual expense ratio will be the expense ratio for the fund classes for any of the years shown. To the extent that Invesco Aim Advisors, Inc. and certain of its affiliates make any fee waivers and/or expense reimbursements pursuant to a voluntary arrangement, your actual expenses may be less. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

AIM TAX-FREE INTERMEDIATE FUND

INVESTMENT OBJECTIVE, STRATEGIES AND RISKS

OBJECTIVE AND STRATEGIES
The fund's investment objective is to generate as high a level of tax-exempt income as is consistent with preservation of capital.

The fund's investment objective may be changed by the Board of Trustees without shareholder approval.

The fund will invest, normally, at least 80% of its net assets, plus the amount of borrowings for investment purposes, in municipal debt securities that
(1) pay interest that is excluded from gross income for federal income tax purposes, and (2) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. In complying with this 80% investment requirement, the fund's investments may include synthetic instruments that in judgment of the fund's advisor have economic characteristics similar to the fund's direct investments. At the present time, the fund will not invest in municipal debt securities if the interest on such securities is subject to the federal alternative minimum tax.

The principal type of municipal debt securities purchased by the fund are municipal bonds, which include revenue bonds and general obligation bonds.

Municipal debt securities include debt obligations of states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies, and instrumentalities, authorities thereof, and multi-state agencies, issued to obtain funds for various public purposes. Municipal lease obligations, synthetic municipal securities and industrial development bonds are treated as municipal debt securities.

At least 80% of the fund's assets will normally be invested in municipal debt securities that are determined to be of investment grade quality, because they meet one of the following quality criteria at the time of purchase: (1) securities rated within the four highest ratings for long-term municipal obligations by Moody's Investors Service, Inc. (Moody's), Standard & Poor's Ratings Services (S&P) or any other nationally recognized statistical rating organization (NRSRO); (2) (a) securities rated within the three highest ratings for short-term municipal obligations by Moody's, or (b) securities rated within the two highest ratings for short-term municipal obligations by S&P, or (c) securities deemed by the portfolio managers to be of comparable quality to the securities set forth in 2(a) or 2(b); (3) securities guaranteed as to payment of principal and interest by the U.S. Government; (4) securities fully collateralized by an escrow of U.S. Government or other high-quality securities; or (5) unrated securities, if (a) other municipal securities of the same issuer are rated BBB or better by an NRSRO, or (b) they are deemed by the portfolio managers to be of comparable quality.

Up to 20% of the fund's assets may be invested in municipal debt securities that are determined to be below investment grade quality because they are rated BB or lower by an NRSRO, or are determined by a portfolio manager to be of comparable quality to such rated securities. These types of securities are commonly known as "junk bonds." The amount of the fund's investments in these types of securities varies from time to time but will not exceed more than 20% of the fund's assets.

The fund's investments in the types of securities described in this prospectus vary from time to time, and, at any time, the fund may not be invested in all types of securities described in this prospectus. Any percentage limitations with respect to assets of the fund are applied at the time of purchase.

In constructing the fund's portfolio, the portfolio managers attempt to control price volatility by purchasing bonds trading at a premium to par, which bonds generally have less price volatility than bonds trading at a discount.

The fund will attempt to maintain a dollar-weighted average portfolio maturity of between three and ten years. The portfolio managers determine which municipal bond sectors have compelling value and what maturities are needed in order to maintain the fund's duration (a measure of the fund's price sensitivity to changes in interest rates). The portfolio managers may, from time to time, shorten or lengthen the duration of the fund's portfolio to protect principal in the event of rising or falling interest rates.

The portfolio managers normally hold municipal bonds to maturity. The portfolio managers consider selling a security: (i) if the issuer's credit quality declines, (ii) to shorten or lengthen the fund's duration, (iii) as a result of interest rate changes, or (iv) to limit exposure to a sector or issuer.

The fund typically maintains a portion of its assets in cash, cash equivalents, high quality debt instruments, and/or money market funds advised by the fund's advisor. Depending upon the then-current investment environment, holding a relatively larger percentage of portfolio assets in such instruments may either assist or hinder the fund's relative performance and its ability to achieve its investment objective. The fund holds cash to handle its daily cash needs, which include payment of fund expenses, redemption requests and securities transactions. In order to respond to adverse market, economic or other conditions, the fund may assume a temporary defensive position and invest a relatively larger percentage of the fund's portfolio assets in cash, cash equivalents or high quality debt instruments.

RISKS
The principal risks of investing in the fund are:

Market Risk--The prices of and the income generated by securities held by the fund may decline in response to certain events, including those directly involving the issuers, or in the case of industrial development revenue bonds, the company for whose benefit the bonds are being issued; general economic and market conditions; regional or global economic instability; and interest rate fluctuations.

Interest Rate Risk--Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on specific characteristics of each bond.

Credit Risk--Credit risk is the risk of loss on an investment due to the deterioration of an issuer's financial health. Such a deterioration of financial health may result in a reduction of the credit rating of the issuer's securities and may lead to the issuer's inability to honor its contractual obligations

AIM TAX-FREE INTERMEDIATE FUND

including making timely payment of interest and principal. Credit ratings are a measure of credit quality. Although a downgrade or upgrade of a bond's credit ratings may or may not affect its price, a decline in credit quality may make bonds less attractive, thereby driving up the yield on the bond and driving down the price. Declines in credit quality may result in bankruptcy for the issuer and permanent loss of investment. Revenue bonds are generally not backed by the taxing power of the issuing municipality and therefore are subject to a higher degree of credit risk than general obligation bonds.

High Yield Risk--High yield risk is a form of credit risk. High yield bonds or "junk bonds" are bonds rated below investment grade or deemed to be of comparable quality. They are considered to be speculative investments with greater risk of failure to make timely payment of interest and principal (to default on their contractual obligations) than their investment grade counterparts. High yield bonds may exhibit increased price sensitivity and reduced liquidity generally and particularly during times economic downturn or volatility in the capital markets.

Reinvestment Risk--Reinvestment risk is the risk that a bond's cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. If interest rates decline, the underlying bond may rise in value, but the cash flows received from that bond may have to be invested at a lower interest rate.

Municipal Securities Risk--The value of, payment of interest and repayment of principal with respect to, and the ability of the fund to sell, a municipal security may be affected by constitutional amendments, legislative enactments, executive orders, administrative regulations and voter initiatives as well as the economics of the regions in which the issuers in which the fund invests are located. Municipal securities backed by current or anticipated revenues from a specific project or assets, such as revenue bonds, can be negatively affected by the discontinuance of the taxation supporting the project or assets or the inability to collect revenues for the project or from the assets. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated as taxable, which could result in a decline in the security's value. To the extent that a municipal security in which the fund invests is not heavily followed by the investment community or such security issue is relatively small, the security may be difficult to value or sell at a fair price.

Concentration Risk--Because many municipal securities are issued to finance similar projects, especially those relating to education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal securities market and the fund. Moreover, sizeable investments in securities issued to finance similar projects could involve an increased risk to the fund if economic or other factors adversely affect the viability of these projects.

Derivatives Risk--The value of "derivatives" or "synthetics"--so-called because their value "derives" from the value of an underlying asset (including an underlying security), reference rate or index--may rise or fall more rapidly than other investments. For some derivatives, it is possible to lose more than the amount invested in the derivative. Derivatives may be used to create synthetic exposure to an underlying asset or to hedge portfolio risk. If the fund uses derivatives to "hedge" a portfolio risk, it is possible that the hedge may not succeed. This may happen for various reasons, including unexpected changes in the value of the rest of the fund's portfolio. Over the counter derivatives are also subject to counterparty risk, which is the risk that the other party to the contract will not fulfill its contractual obligation to complete the transaction with the fund.

Synthetic Municipal Securities Risk--The tax-exempt character of the interest paid on synthetic municipal securities is based on the tax-exempt income stream from the collateral. The Internal Revenue Service has not ruled on this issue and could deem income derived from synthetic municipal securities to be taxable.

Leverage Risk--If the fund borrows money to finance investments, it is engaging in a practice known as "leveraging." If the prices of those investments decrease, or if the cost of borrowing exceeds any increases in the prices of those investments, the net asset value of the fund's shares will decrease faster than if the fund had not used leverage. To repay borrowings, the fund may have to sell investments at a time and at a price that is unfavorable to the fund. Interest on borrowings is an expense the fund would not otherwise incur. There can be no assurance that the fund will use leverage or should the fund use leverage, that the fund's leverage strategy will be successful.

Management Risk--There is no guarantee that the investment techniques and risk analyses used by the fund's portfolio manager(s) will produce the desired results.

OTHER INFORMATION

SALES CHARGES
Purchases of Class A shares of AIM Tax-Free Intermediate Fund are subject to the maximum 1.00% initial sales charge as listed under the heading "CATEGORY III Initial Sales Charges" in the "General Information--Initial Sales Charges (Class A Shares Only)" section of this prospectus.

DIVIDENDS AND DISTRIBUTIONS

The fund expects that its distributions, if any, will consist primarily of income (most of which is expected to be exempt from federal income taxes).

DIVIDENDS

The fund generally declares dividends from net investment income on each business day and pays dividends, if any, monthly.

CAPITAL GAINS DISTRIBUTIONS

The fund generally distributes long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Capital gains distributions may vary considerably from year to year as a result of the fund's normal investment activities and cash flows.

SPECIAL TAX INFORMATION REGARDING THE FUND

In addition to the general tax information set forth under the heading "General Information--Taxes" in this prospectus, the following information describes the tax impact of certain dividends you may receive from the fund:

- You will not be required to include the "exempt-interest" portion of dividends paid by the fund in your gross income for federal income tax purposes. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax return.

- The fund may invest a portion of its assets in securities that pay income that is not tax-exempt. The fund also may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of non- corporate shareholders.

- The fund may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for you, and may invest up to 20% of its net assets in such securities and other taxable securities. The fund will try to avoid investments that result in taxable dividends.

- Exempt-interest dividends from the fund are taken into account when determining the taxable portion of your social security or railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.

- The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the fund for the particular days in which you hold shares.

- From time to time, proposals have been introduced before Congress that would have the effect of reducing or eliminating the federal tax exemption on municipal securities. If such a proposal were enacted, the ability of the fund to pay exempt-interest dividends might be adversely affected.

CLOSURE OF CLASS A SHARES
The fund discontinued public sales of its Class A shares to new investors at the close of business on October 30, 2002.

Existing shareholders of the fund may continue to invest in Class A shares of the fund if they were invested in the Class A shares of the fund at the close of business on October 30, 2002 and remain invested in Class A shares of the fund after that date.

THE AIM FUNDS

General Information

In addition to the fund, Invesco Aim serves as investment advisor to many other mutual funds that are offered to retail investors. The following information is about all the AIM funds that offer retail share classes.

CHOOSING A SHARE CLASS

Each of the funds offer multiple classes of shares. Each class represents an interest in the same portfolio of investments. Certain classes have higher expenses than other classes which may lower the return on your investment when compared to a less expensive class. In deciding which class of shares to purchase, you should consider the following attributes of the various share classes, among other things: (i) the eligibility requirements that apply to purchases of a particular class, (ii) the initial sales charges and contingent deferred sales charges (CDSCs), if any, applicable to the class, (iii) the 12b-1 fee, if any, paid by the class, and (iv) any services you may receive from a financial intermediary. Please contact your financial advisor to assist you in making your decision. Please refer to the prospectus fee table for more information on the fees and expenses of a particular fund's share classes. In addition to the share classes shown in the chart below, AIM Money Market Fund offers AIM Cash Reserve Shares and AIM Summit Fund offers Class P shares.

(1) Class A shares of AIM Tax-Free Intermediate Fund and Investor Class shares of AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio do not have a 12b-1 fee.

(3) CDSC does not apply to redemption of Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund unless you received Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund through an exchange from Class C shares from another AIM Fund that is still subject to a CDSC.

(4) Class C shares of AIM Floating Rate Fund have a 12b-1 fee of 0.75%.

SHARE CLASS ELIGIBILITY

CLASS A, A3, B, C AND AIM CASH RESERVE SHARES

Class A, A3, B, C and AIM Cash Reserve Shares are available to all retail investors, including individuals, trusts, corporations and other business and charitable organizations and employee benefit plans. The share classes offer different fee structures which are intended to compensate financial intermediaries for services provided in connection with the sale of shares and continued maintenance of the customer relationship. You should consider the services provided by your financial advisor and any other intermediaries who will be involved in the servicing of your account when choosing a share class.

Class B shares are not available as an investment for retirement plans maintained pursuant to Section 401 of the Internal Revenue Code (the Code). These plans include 401(k) plans (including AIM Solo 401(k) plans), money purchase pension plans and profit sharing plans. However, plans that have existing accounts invested in Class B shares will continue to be allowed to make additional purchases.

CLASS P SHARES

In addition to the other share classes discussed herein, the AIM Summit Fund offers Class P shares, which were historically sold only through the AIM Summit Investors Plans I and II (each a Plan and, collectively, the Summit Plans). Class P shares are sold with no initial sales charge and have a 12b-1 fee of 0.10%. However, Class P shares are not sold to members of the general public. Only shareholders who had accounts in the Summit Plans at the close of business on December 8, 2006 may purchase Class P shares and only until the total of their combined investments in the Summit Plans and in Class P shares directly equals the face amount of their former Plan under the 30 year extended investment option. The face amount of a Plan is the combined total of all scheduled monthly investments under the Plan. For a Plan with a scheduled monthly investment of $100.00, the face amount would have been $36,000.00 under the 30 year extended investment option.

THE AIM FUNDS

CLASS R SHARES

Class R shares are generally available only to employee benefit plans. These may include, for example, retirement and deferred compensation plans maintained pursuant to Sections 401, 403, and 457 of the Code; nonqualified deferred compensation plans; health savings accounts maintained pursuant to Section 223 of the Code; and voluntary employees' beneficiary arrangements maintained pursuant to Section 501(c)(9) of the Code. Retirement plans maintained pursuant to Section 401 generally include 401(k) plans, profit sharing plans, money purchase pension plans, and defined benefit plans. Retirement plans maintained pursuant to Section 403 must be established and maintained by non-profit organizations operating pursuant to Section 501(c)(3) of the Code in order to purchase Class R shares. Class R shares are generally not available for individual retirement accounts (IRAs) such as traditional, Roth, SEP, SAR-SEP and SIMPLE IRAs.

INVESTOR CLASS SHARES

Some of the funds offer Investor Class shares. Investor Class shares are sold with no initial sales charge and have a maximum 12b-1 fee of 0.25%. Investor Class shares are not sold to members of the general public. Only the following persons may purchase Investor Class shares:

- Investors who established accounts prior to April 1, 2002, in Investor Class shares who have continuously maintained an account in Investor Class shares (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons). These investors are referred to as "grandfathered investors."

- Customers of certain financial intermediaries which have had relationships with the funds' distributor or any funds that offered Investor Class shares prior to April 1, 2002, who have continuously maintained such relationships. These intermediaries are referred to as "grandfathered intermediaries."

- Employee benefit plans; provided, however, that retirement plans maintained pursuant to Section 403 must be established and maintained by non-profit organizations operating pursuant to Section 501(c)(3) of the Code in order to purchase Investor Class shares, unless the plan is considered a grandfathered investor or the account is opened through a grandfathered intermediary. Investor Class shares are generally not available for IRAs, unless the IRA depositor is considered a grandfathered investor or the account is opened through a grandfathered intermediary.

- Any trustee, director, officer or employee of any fund or of Invesco Ltd. or any of its subsidiaries or affiliates, or any employee benefit plan maintained by any of them (this includes any immediate family members of such persons).

DISTRIBUTION AND SERVICE (12B-1) FEES

Except as noted below, each fund has adopted a distribution plan pursuant to SEC Rule 12b-1. A 12b-1 plan allows a fund to pay distribution fees to Invesco Aim Distributors, Inc. (Invesco Aim Distributors) to compensate or reimburse, as applicable, Invesco Aim Distributors for its efforts in connection with the sale and distribution of the fund's shares and for services provided to shareholders, all or a substantial portion of which are paid to the dealer of record. Because the funds pay these fees out of their assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

The following funds and share classes do not have 12b-1 plans:

- AIM Tax-Free Intermediate Fund, Class A shares.

- AIM Money Market Fund, Investor Class shares.

- AIM Tax-Exempt Cash Fund, Investor Class shares.

- Premier Portfolio, Investor Class shares.

- Premier U.S. Government Money Portfolio, Investor Class shares.

- Premier Tax-Exempt Portfolio, Investor Class shares.

INITIAL SALES CHARGES (CLASS A SHARES ONLY)

The funds are grouped into four categories for determining initial sales charges. The "Other Information" section of each fund's prospectus will tell you the sales charge category in which the fund is classified. As used below, the term "offering price" with respect to all categories of Class A shares includes the initial sales charge.

CLASS A SHARES SOLD WITHOUT AN INITIAL SALES CHARGE

Certain categories of investors are permitted to purchase and certain intermediaries are permitted to sell Class A shares of the funds without an initial sales charge because their transactions involve little or no expense. The investors who are entitled to purchase Class A shares without paying an initial sales charge include the following:

- Any current or retired trustee, director, officer or employee of any fund or of Invesco Ltd. or any of its subsidiaries or affiliates, or any foundation, trust or employee benefit plan maintained by any of them (this includes any immediate family members of such persons).

- Any registered representative or employee of any intermediary who has an agreement with Invesco Aim Distributors to sell shares of the funds (this includes any immediate family members of such persons).

- Any investor who purchases their shares through an approved fee-based program (this may include any type of account for which there is some alternative arrangement made between the investor and the intermediary to provide for compensation of the intermediary for services rendered in connection with the sale of the shares and maintenance of the customer relationship).

- Any investor who purchases their shares with the proceeds of a rollover, transfer or distribution from a retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor to another retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor, to the extent that such proceeds are attributable to the redemption of shares of a fund held through the plan or account.

- Employee benefit plans; provided, however, that they meet at least one of the following requirements:

a. the plan has assets of at least $1 million;

b. there are at least 100 employees eligible to participate in the plan; or

c. all plan transactions are executed through a single omnibus account per fund; further provided that retirement plans maintained pursuant to Section 403(b) of the Code are not eligible to purchase shares without paying an initial sales charge based on the aggregate investment made by the plan or the number of eligible employees unless the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code.

- Any investor who maintains an account in Investor Class shares of a fund (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and immediate family members of such persons).

Additional information regarding eligibility to purchase shares at reduced or without sales charges is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

You may qualify for reduced sales charges or sales charge exceptions. To qualify for these reductions or exceptions, you or your financial advisor must notify the transfer agent at the time of purchase that your purchase qualifies for such treatment. Certain individuals and employer-sponsored retirement plans may link accounts for the purpose of qualifying for lower initial sales charges. You or your financial consultant must provide other account numbers to be considered for Rights of Accumulation, or mark the Letter of Intent section on the account application, or provide other relevant documentation, so that the transfer agent can verify your eligibility for the reduction or exception. Please consult the fund's Statement of Additional Information for details.

Purchases of Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund, AIM Cash Reserve Shares of AIM Money Market Fund and Investor Class shares of any fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges pursuant to Rights of Accumulation or Letters of Intent.

THE AIM FUNDS

RIGHTS OF ACCUMULATION

You may combine your new purchases of Class A shares of a fund with other fund shares currently owned (Class A, B, C, P or R) and investments in the AIM College Savings Plan(R) for the purpose of qualifying for the lower initial sales charge rates that apply to larger purchases. The applicable initial sales charge for the new purchase is based on the total of your current purchase and the public offering price of all other shares you own. The transfer agent may automatically link certain accounts registered in the same name with the same taxpayer identification number for the purpose of qualifying you for lower initial sales charge rates. There may be other accounts that are eligible to be linked, as described in the fund's Statement of Additional Information. However, if the accounts are not registered in the same name with the same taxpayer identification number, you will have to contact the transfer agent to request that those accounts be linked. The transfer agent will not be responsible for identifying all accounts that may be eligible to be linked.

LETTERS OF INTENT

Under a Letter of Intent (LOI), you commit to purchase a specified dollar amount of Class A shares of one or more funds during a 13-month period. The amount you agree to purchase determines the initial sales charge you pay. If the full amount committed to in the LOI is not invested by the end of the 13-month period, your account will be assessed the higher initial sales charge that would normally be applicable to the amount actually invested.

REINSTATEMENT FOLLOWING REDEMPTION

If you redeem shares of a fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B and P redemptions may be reinvested only into Class A shares with no initial sales charge. This reinstatement privilege does not apply to:

- A purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account, or

- A purchase paid for with proceeds from the redemption of shares that were held indirectly through an employee benefit plan.

In order to take advantage of this reinstatement privilege, you must inform your financial advisor or the transfer agent that you wish to do so at the time of your investment.

CONTINGENT DEFERRED SALES CHARGES (CDSCS)

CDSCS ON CLASS A SHARES AND AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND

You can purchase $1,000,000 or more (a Large Purchase) of Class A shares of Category I, II and IV funds without paying an initial sales charge. However, if you redeem these shares prior to 18 months after the date of purchase, they will be subject to a CDSC of 1%.

If you currently own Class A shares of a Category I, II or IV fund, and make additional purchases without paying an initial sales charge that result in account balances of $1,000,000 or more, the additional shares purchased will be subject to an 18-month, 1% CDSC.

If Invesco Aim Distributors pays a concession to the dealer of record in connection with a Large Purchase of Class A shares by an employee benefit plan, the Class A shares may be subject to a 1% CDSC if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

If you acquire AIM Cash Reserve Shares of AIM Money Market Fund, Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund or AIM Tax-Free Intermediate Fund through an exchange involving Class A shares that were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC.

CDSCS ON CLASS B SHARES AND ON CLASS C SHARES OF FUNDS OTHER THAN AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class B and Class C shares are sold without an initial sales charge. However, they are subject to a CDSC. If you redeem your shares during the CDSC period, you will be assessed a CDSC as follows, unless you qualify for one of the CDSC exceptions outlined below:

YEAR SINCE PURCHASE MADE:   CLASS B   CLASS C
-------------------------   -------   -------
First                           5%         1%
Second                          4       None
Third                           3       None

Fifth                           2      None
Sixth                           1      None
Seventh and following        None      None

CDSCS ON CLASS C SHARES -- EMPLOYEE BENEFIT PLAN

Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class C shares by an employee benefit plan; the Class C shares are subject to a 1.00% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

CDSCS ON CLASS C SHARES OF AIM LIBOR ALPHA FUND AND AIM SHORT TERM BOND FUND

Class C shares of AIM LIBOR Alpha Fund and AIM Short Term Bond Fund are not normally subject to a CDSC. However, if you acquired shares of those funds through an exchange, and the shares originally purchased were subject to a CDSC, the shares acquired as a result of the exchange will continue to be subject to that same CDSC. Conversely, if you acquire Class C shares of any other fund as a result of an exchange involving Class C shares of

A-4

THE AIM FUNDS

AIM LIBOR Alpha Fund or AIM Short Term Bond Fund that were not subject to a CDSC, then the shares acquired as a result of the exchange will not be subject to a CDSC.

CDSCS ON CLASS R SHARES

Class R shares are not normally subject to a CDSC. However, if Invesco Aim Distributors pays a concession to the dealer of record in connection with a purchase of Class R shares by an employee benefit plan, the Class R shares are subject to a 0.75% CDSC at the time of redemption if all of the plan's shares are redeemed within one year from the date of the plan's initial purchase.

COMPUTING A CDSC

The CDSC on redemptions of shares is computed based on the lower of their original purchase price or current net asset value, net of reinvested dividends and capital gains distributions. In determining whether to charge a CDSC, shares are accounted for on a first-in, first-out basis, which means that you will redeem shares on which there is no CDSC first and, then, shares in the order of their purchase.

CDSC EXCEPTIONS

Investors who own shares that are otherwise subject to a CDSC will not pay a CDSC in the following circumstances:

- If you participate in the Systematic Redemption Plan and withdraw up to 12% of the value of your shares that are subject to a CDSC in any twelve-month period.

- If you redeem shares to pay account fees.

- If you are the executor, administrator or beneficiary of an estate or are otherwise entitled to assets remaining in an account following the death or post-purchase disability of a shareholder or beneficial owner and you choose to redeem those shares.

There are other circumstances under which you may be able to redeem shares without paying CDSCs. Additional information regarding CDSC exceptions is available on the Internet at www.invescoaim.com, then click on the link for My Account, then Service Center, or consult the fund's Statement of Additional Information, which is available on that same website or upon request free of charge.

Shares acquired through the reinvestment of dividends and distributions are not subject to CDSCs.

The following share classes are sold with no CDSC:

- Class A shares of any Category III Fund.

- Class A shares of AIM Tax-Exempt Cash Fund.

- Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund.

- AIM Cash Reserve Shares of AIM Money Market Fund.

- Investor Class shares of any fund.

- Class P shares of AIM Summit Fund.

REDEMPTION FEES

Certain funds impose a 2% redemption fee (on redemption proceeds) if you redeem or exchange shares within 31 days of purchase. Please refer to the applicable fund's prospectus to determine whether that fund imposes a redemption fee. As of the date of this prospectus, the following funds impose redemption fees:

AIM Asia Pacific Growth Fund
AIM China Fund
AIM Developing Markets Fund
AIM European Growth Fund
AIM European Small Company Fund
AIM Floating Rate Fund
AIM Global Core Equity Fund
AIM Global Equity Fund
AIM Global Growth Fund
AIM Global Health Care Fund
AIM Global Real Estate Fund
AIM Global Small & Mid Cap Growth Fund
AIM Gold & Precious Metals Fund
AIM High Yield Fund
AIM International Allocation Fund
AIM International Core Equity Fund
AIM International Growth Fund
AIM International Small Company Fund
AIM International Total Return Fund
AIM Japan Fund
AIM Trimark Fund

The redemption fee will be retained by the fund from which you are redeeming or exchanging shares, and is intended to offset the trading costs, market impact and other costs associated with short-term money movements in and out of the fund. The redemption fee is imposed on a first-in, first-out basis, which means that you will redeem shares in the order of their purchase.

A-5

THE AIM FUNDS

Redemption fees generally will not be charged in the following circumstances:

- Redemptions and exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to assess the redemption fees.

- Redemptions and exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, variable insurance contracts or separately managed qualified default investment alternative vehicles maintained pursuant to Section 404(c)(5) of the Employee Retirement Income Security Act of 1974, as amended (ERISA), which use the funds as underlying investments.

- Redemptions and exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs or systematic withdrawal plans.

- Redemptions requested within 31 days following the death or post-purchase disability of an account owner.

- Redemptions or exchanges initiated by a fund.

The following shares are not subject to redemption fees, irrespective of whether they are redeemed in accordance with any of the exceptions set forth above:

- Shares acquired through the reinvestment of dividends and distributions.

- Shares acquired through systematic purchase plans.

- Shares acquired in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan to the trustee or custodian of another employee benefit plan.

Shares held by employee benefit plans will only be subject to redemption fees if the shares were acquired by exchange and are redeemed by exchange within 31 days of purchase.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

The funds have the discretion to waive the 2% redemption fee if a fund is in jeopardy of losing its registered investment company qualification for tax purposes.

Your financial advisor or other intermediary may charge service fees for handling redemption transactions. Your shares also may be subject to a CDSC in addition to the redemption fee.

PURCHASING SHARES

If you hold your shares through a financial advisor or other intermediary, your eligibility to purchase shares and the terms by which you may purchase, redeem and exchange shares may differ depending on that institution's policies.

MINIMUM INVESTMENTS

There are no minimum investments for Class P or R shares for fund accounts. The minimum investments for Class A, A3, B, C, and Investor Class shares for fund accounts are as follows:

Purchase orders will not be processed unless the account application and purchase payment are received in good order. In accordance with the USA PATRIOT Act, if you fail to provide all the required information requested in the current account application, your purchase order will not be processed. Additionally, federal law requires that the fund verify and record your identifying information.

SYSTEMATIC PURCHASE PLAN

You can arrange for periodic investments in any of the funds by authorizing the transfer agent to withdraw the amount of your investment from your bank account on a day or dates you specify and in an amount of at least $50 per fund. You may stop the Systematic Purchase Plan at any time by giving the transfer agent notice ten days prior to your next scheduled withdrawal. Certain financial advisors and other intermediaries may also offer systematic purchase plans.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic periodic exchanges, if permitted, from one fund to another fund or multiple other funds. The account from which exchanges are to be made must have a minimum balance of $5,000 before you can use this option. Exchanges will occur on (or about) the day of the month you specify, in the amount you specify. Dollar Cost Averaging cannot be set up for the 29th through the 31st of the month. The minimum amount you can exchange to another fund is $50. Certain financial advisors and other intermediaries may also offer dollar cost averaging programs. If you participate in one of these programs and it is the same or similar to Invesco Aim's Dollar Cost Averaging program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

AUTOMATIC DIVIDEND AND DISTRIBUTION INVESTMENT

Your dividends and distributions may be paid in cash or reinvested in the same fund or another fund without paying an initial sales charge. Unless you specify otherwise, your dividends and distributions will automatically be reinvested in the same fund. If you elect to receive your distributions by check, and the distribution amount is $10 or less, then the amount will be automatically reinvested in the same fund and no check will be issued. If you have elected to receive distributions by check, and the postal service is unable to deliver checks to your address of record, then your distribution election may be converted to having all subsequent distributions reinvested in the same fund and no checks will be issued. You should contact the transfer agent to change your distribution option, and your request to do so must be received by the transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

You must comply with the following requirements to be eligible to invest your dividends and distributions in shares of another fund:

- Your account balance in the fund paying the dividend or distribution must be at least $5,000; and

- Your account balance in the fund receiving the dividend or distribution must be at least $500.

PORTFOLIO REBALANCING PROGRAM

If you have at least $5,000 in your account, you may participate in the Portfolio Rebalancing Program. Under this Program, you can designate how the total value of your fund holdings should be rebalanced, on a percentage basis, between two and ten of your funds on a quarterly, semiannual or annual basis. Your portfolio will be rebalanced through the exchange of shares in one or more of your funds for shares of the same class of one or more other funds in your portfolio. Rebalancing will not occur if your portfolio is within 2% of your stated allocation. If you wish to participate in the Program, make changes or cancel the Program, the transfer agent must receive your request to participate, changes, or cancellation in good order at least five business days prior to the next rebalancing date, which is normally the 28th day of the last month of the period you choose. We may modify, suspend or terminate the Program at any time on 60 days' prior written notice to participating investors. Certain financial advisors and other intermediaries may also offer portfolio rebalancing programs. If you participate in one of these programs and it is the same as or similar to Invesco Aim's program, exchanges made under the program generally will not be counted toward the limitation of four exchanges out of a fund per calendar year, discussed below.

RETIREMENT PLANS SPONSORED BY INVESCO AIM DISTRIBUTORS

These plan documents are generally available to anyone wishing to invest plan assets in the funds. These documents are provided subject to terms, conditions and fees that vary by plan type.

REDEEMING SHARES

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call during the hours of the customary trading session of the New York Stock Exchange (NYSE) in order to effect the redemption at that day's net asset value. For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, the transfer agent must receive your call before the last net asset value determination in order to effect the redemption that day.

THE AIM FUNDS

TIMING AND METHOD OF PAYMENT

We normally will send out payments within one business day, and in any event no more than seven days, after your redemption request is received in good order (meaning that all necessary information and documentation related to the redemption request have been provided to the transfer agent). If you redeem shares recently purchased by check or ACH, you may be required to wait up to ten business days before we send your redemption proceeds. This delay is necessary to ensure that the purchase has cleared. Payment may be postponed in cases where the SEC declares an emergency or normal trading is halted on the NYSE.

Redemption checks are mailed to your address of record, via first class U.S. mail, unless you make other arrangements with the transfer agent.

We use reasonable procedures to confirm that instructions communicated via telephone and the Internet are genuine, and we are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

EXPEDITED REDEMPTIONS (AIM CASH RESERVE SHARES OF AIM MONEY MARKET FUND ONLY)

If you place your redemption order by telephone, before 11:30 a.m. Eastern Time and request an expedited redemption, we will transmit payment of redemption proceeds on that same day via federal wire to a bank of record on your account. If we receive your redemption order after 11:30 a.m. Eastern Time and before the close of the customary trading session of the NYSE, we will transmit payment on the next business day.

SYSTEMATIC WITHDRAWALS

You may arrange for regular periodic withdrawals from your account in amounts equal to or greater than $50 per fund. We will redeem the appropriate number of shares from your account to provide redemption proceeds in the amount requested. You must have a total account balance of at least $5,000 in order to establish a Systematic Redemption Plan, unless you are establishing a Required Minimum Distribution for a retirement plan. You can stop this plan at any time by giving ten days prior notice to the transfer agent.

CHECK WRITING

The transfer agent provides check writing privileges for accounts in the following funds and share classes:

- AIM Money Market Fund, AIM Cash Reserve Shares and Investor Class shares

- AIM Tax-Exempt Cash Fund, Class A shares and Investor Class shares

- Premier Portfolio, Investor Class shares

- Premier Tax-Exempt Portfolio, Investor Class shares

- Premier U.S. Government Money Portfolio, Investor Class shares

You may redeem shares of these funds by writing checks in amounts of $250 or more if you have completed an authorization form. Redemption by check is not available for retirement accounts. Checks are not eligible to be converted to ACH by the payee. You may not give authorization to a payee by phone to debit your account by ACH for a debt owed to the payee.

SIGNATURE GUARANTEES

We require a signature guarantee in the following circumstances:

- When your redemption proceeds will equal or exceed $250,000 per fund.

- When you request that redemption proceeds be paid to someone other than the registered owner of the account.

- When you request that redemption proceeds be sent somewhere other than the address of record or bank of record on the account.

- When you request that redemption proceeds be sent to a new address or an address that changed in the last 30 days.

The transfer agent will accept a guarantee of your signature by a number of different types of financial institutions. Call the transfer agent for additional information. Some institutions have transaction amount maximums for these guarantees. Please check with the guarantor institution to determine whether the signature guarantee offered will be sufficient to cover the value of your transaction request.

REDEMPTIONS IN KIND

Although the funds generally intend to pay redemption proceeds solely in cash, the funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind).

REDEMPTIONS INITIATED BY THE FUNDS

If your account (Class A, A3, B, C, P and Investor Class shares only) has been open at least one year, you have not made an additional purchase in the account during the past six calendar months, and the value of your account falls below $500 for three consecutive months, the funds have the right to redeem the account after giving you 60 days' prior written notice. You may avoid having your account redeemed during the notice period by bringing the account value up to $500 or by initiating a Systematic Purchase Plan.

If the fund determines that you have not provided a correct Social Security or other tax identification number on your account application, or the fund is not able to verify your identity as required by law, the fund may, at its discretion, redeem the account and distribute the proceeds to you.

EXCHANGING SHARES

You may, under certain circumstances, exchange shares in one fund for those of another fund. An exchange is the purchase of shares in one fund which

A-9

THE AIM FUNDS

is paid for with the proceeds from a redemption of shares of another fund effectuated on the same day. Accordingly, the procedures and processes applicable to redemptions of fund shares, as discussed under the heading "Redeeming Shares" above, will apply. Before requesting an exchange, review the prospectus of the fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the funds. If you wish to exchange shares of one fund for those of another fund, you must consult the prospectus of the fund whose shares you wish to acquire to determine whether the fund is offering shares to new investors and whether you are eligible to acquire shares of that fund.

PERMITTED EXCHANGES

Except as otherwise provided below under "Exchanges Not Permitted", you generally may exchange your shares for shares of the same class of another fund. The following below shows permitted exchanges:

     EXCHANGE FROM                             EXCHANGE TO
-----------------------   ------------------------------------------------------
AIM Cash Reserve Shares   Class A, A3, B, C, R, Investor Class
Class A                   Class A, A3, Investor Class, AIM Cash Reserve Shares
Class A3                  Class A, A3, Investor Class, AIM Cash Reserve Shares
Investor Class            Class A, A3, Investor Class
Class P                   Class A, A3, AIM Cash Reserve Shares
Class B                   Class B
Class C                   Class C
Class R                   Class R

EXCHANGES NOT PERMITTED

The following exchanges are not permitted:

- Investor Class shares cannot be exchanged for Class A shares of any fund which offers Investor Class shares.

- Exchanges into Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund (also known as the Category III funds) are not permitted.

- Class A Shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund cannot be exchanged for Class A3 Shares of those funds.

- AIM Cash Reserve Shares cannot be exchanged for Class B, C or R shares if the shares being exchanged were acquired by exchange from Class A shares of any fund.

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

- Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested; and

- If you have physical share certificates, you must return them to the transfer agent in order to effect the exchange.

Under unusual market conditions, a fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares. Any of the participating funds or the distributor may modify or terminate this privilege at any time.

LIMIT ON THE NUMBER OF EXCHANGES

You will generally be limited to four exchanges out of a fund per calendar year (other than the money market funds); provided, however, that the following transactions will not count toward the exchange limitation:

- Exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to apply the exchange limitation.

- Exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, and insurance company separate accounts which use the funds as underlying investments.

- Generally, exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs.

- Exchanges initiated by a fund or by the trustee, administrator or other fiduciary of an employee benefit plan (not in response to distribution or exchange instructions received from a plan participant).

Each fund reserves the discretion to accept exchanges in excess of these guidelines on a case-by-case basis if the fund, or its designated agent, believes that granting such exceptions would be consistent with the best interests of shareholders.

There is no limit on the number of exchanges out of AIM Limited Maturity Treasury Fund, AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio.

If you exchange shares of one fund for shares of multiple other funds as part of a single transaction, that transaction is counted as one exchange out of a fund.

INITIAL SALES CHARGES AND CDSCS APPLICABLE TO EXCHANGES

You may be required to pay an initial sales charge when exchanging from a fund with a lower initial sales charge than the one into which you are exchanging. If you exchange into shares that are subject to a CDSC, we will begin the holding period for purposes of calculating the CDSC on the date

A-10

THE AIM FUNDS

you made your initial purchase.

RIGHTS RESERVED BY THE FUNDS

Each fund and its agents reserve the right at any time to:

- Reject or cancel all or any part of any purchase or exchange order.

- Modify any terms or conditions related to the purchase, redemption or exchange of shares of any fund.

- Reject or cancel any request to establish a Systematic Purchase Plan, Systematic Redemption Plan or Portfolio Rebalancing Program.

- Suspend, change or withdraw all or any part of the offering made by this prospectus.

PRICING OF SHARES

DETERMINATION OF NET ASSET VALUE

The price of each fund's shares is the fund's net asset value per share. The funds value portfolio securities for which market quotations are readily available at market value. The funds value all other securities and assets for which market quotations are unavailable or unreliable at their fair value in good faith using procedures approved by the Boards of Trustees of the funds (collectively, the Board). The Board has delegated the daily determination of good faith fair value methodologies to Invesco Aim's Valuation Committee, which acts in accordance with Board approved policies. On a quarterly basis, Invesco Aim provides the Board various reports indicating the quality and effectiveness of its fair value decisions on portfolio holdings. Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day.

Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the NYSE and when the fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events which affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where market quotations are not readily available, including where Invesco Aim determines that the closing price of the security is unreliable, Invesco Aim will value the security at fair value in good faith using procedures approved by the Board. Fair value pricing may reduce the ability of frequent traders to take advantage of arbitrage opportunities resulting from potentially "stale" prices of portfolio holdings. However, it cannot eliminate the possibility of frequent trading.

Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. Fair value requires consideration of all appropriate factors, including indications of fair value available from pricing services. A fair value price is an estimated price and may vary from the prices used by other mutual funds to calculate their net asset values.

Invesco Aim may use indications of fair value from pricing services approved by the Board. In other circumstances, the Invesco Aim Valuation Committee may fair value securities in good faith using procedures approved by the Board. As a means of evaluating its fair value process, Invesco Aim routinely compares closing market prices, the next day's opening prices for the security in its primary market if available, and indications of fair value from other sources. Fair value pricing methods and pricing services can change from time to time as approved by the Board.

Specific types of securities are valued as follows:

Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.

Domestic Exchange Traded Equity Securities. Market quotations are generally available and reliable for domestic exchange traded equity securities. If market quotations are not available or are unreliable, Invesco Aim will value the security at fair value in good faith using procedures approved by the Board.

Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the fund may fair value the security. If an issuer specific event has occurred that Invesco Aim determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. Invesco Aim also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where Invesco Aim believes, at the approved degree of certainty, that the price is not reflective of current market value, Invesco Aim will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time.

Fund securities primarily traded on foreign markets may trade on days that are not business days of the fund. Because the net asset value of fund shares is determined only on business days of the fund, the value of the portfolio securities of a fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the fund.

Fixed Income Securities. Government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined

A-11

THE AIM FUNDS

without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Invesco Aim valuation committee will fair value the security using procedures approved by the Board.

Short-term Securities. The funds' short-term investments are valued at amortized cost when the security has 60 days or less to maturity. AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio value all their securities at amortized cost. AIM High Income Municipal Fund, AIM Municipal Bond Fund and AIM Tax-Free Intermediate Fund value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.

Futures and Options. Futures contracts are valued at the final settlement price set by the exchange on which they are principally traded. Options are valued on the basis of market quotations, if available.

Swap Agreements. Swap Agreements are fair valued using an evaluated quote provided by an independent pricing service. Evaluated quotes provided by the pricing service are based on a model that may include end of day net present values, spreads, ratings, industry and company performance.

Open-end Funds. To the extent a fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing fund will calculate its net asset value using the net asset value of the underlying fund in which it invests.

Each fund determines the net asset value of its shares on each day the NYSE is open for business (a business day), as of the close of the customary trading session, or earlier NYSE closing time that day. AIM Money Market Fund also determines its net asset value as of 12:00 noon Eastern Time on each business day. Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio determine the net asset value of their shares every fifteen minutes on each business day, beginning at 8:00 a.m. Eastern Time. The last net asset value determination on any business day for Premier Portfolio and Premier U.S. Government Money Portfolio will generally occur at 5:30 p.m. Eastern Time, and the last net asset value determination on any business day for Premier Tax-Exempt Portfolio will generally occur at 4:30 p.m. Eastern Time. Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio are authorized not to open for trading on a day that is otherwise a business day if the Federal Reserve Bank of New York and the Bank of New York, the fund's custodian, are not open for business or the Securities Industry and Financial Markets Association (SIFMA) recommends that government securities dealers not open for trading and any such day will not be considered a business day. Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio also may close early on a business day if SIFMA recommends that government securities dealers close early. If Premier Portfolio, Premier Tax-Exempt Portfolio or Premier U.S. Government Money Portfolio uses its discretion to close early on a business day, the last net asset value calculation will occur as of the time of such closing.

From time to time and in circumstances deemed appropriate by Invesco Aim in its sole discretion, each of Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio may remain open for business, during customary business day hours, on a day that the NYSE is closed for business. In such event, on such day you will be permitted to purchase or redeem shares of such funds and net asset values will be calculated for such funds.

TIMING OF ORDERS

For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, you can purchase or redeem shares on each business day prior to the close of the customary trading session or any earlier NYSE closing time that day. For funds other than Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, purchase orders that are received and accepted before the close of the customary trading session or any earlier NYSE closing time on a business day generally are processed that day and settled on the next business day.

For Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio, you can purchase or redeem shares on each business day, prior to the last net asset value determination on such business day; however, if your order is received and accepted after the close of the customary trading session or any earlier NYSE closing time that day, your order generally will be processed on the next business day and settled on the second business day following the receipt and acceptance of your order.

For all funds, you can exchange shares on each business day, prior to the close of the customary trading session or any earlier NYSE closing time that day. Shareholders of Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio therefore cannot exchange their shares after the close of the customary trading session or any earlier NYSE closing time on a particular day, even though these funds remain open after such closing time.

The funds price purchase, exchange and redemption orders at the net asset value calculated after the transfer agent receives an order in good order. Any applicable sales charges are applied at the time an order is processed. A fund may postpone the right of redemption only under unusual circumstances, as allowed by the Securities and Exchange Commission, such as when the NYSE restricts or suspends trading.

TAXES

In general, if you are a taxable investor, dividends and distributions you receive are taxable as ordinary income or long-term capital gains for federal income tax purposes. This is true whether you reinvest distributions in additional fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from each fund during the prior year. Investors in tax-exempt funds should read the information under the heading "Other Information--Special Tax Information Regarding the Fund" in the applicable fund's prospectus. In addition, investors in taxable accounts should be aware of the following basic tax points:

A-12

THE AIM FUNDS

- Distributions of net short-term capital gains are taxable to you as ordinary income. A fund that is expected to have higher turnover than that of other funds is more likely to generate short-term gain or loss.

- Distributions of net long-term capital gains are taxable to you as long-term capital gains no matter how long you have owned your fund shares.

- If you are an individual and meet certain holding period requirements, a portion of income dividends paid by a fund may be designated as qualified dividend income eligible for taxation at long-term capital gain rates. These reduced rates generally are available for dividends paid by a fund out of dividends earned on the fund's investment in stocks of domestic corporations and qualified foreign corporations.

- Distributions declared to shareholders with a record date in December--if paid to you by the end of January--are taxable for federal income tax purposes as if received in December.

- Any long-term or short-term capital gains realized from redemptions of fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another fund is the same as a sale.

- If you invest in a fund shortly before it makes a capital gains distribution, the distribution will lower the value of the fund's shares by the amount of the distribution and, in effect, you will receive some of your investment back in the form of a taxable distribution. This is sometimes referred to as "buying a dividend."

- By law, if you do not provide a fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A fund also must withhold if the IRS instructs it to do so. When withholding is required, the amount will be 28% of any distributions or proceeds paid.

- Fund distributions and gains from sale or exchange of your fund shares generally are subject to state and local income taxes.

- Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits and estate taxes may apply to an investment in a fund.

The preceding discussion concerning the taxability of fund dividends and distributions and of redemptions and exchanges of fund shares is inapplicable to investors that are generally exempt from federal income tax, such as retirement plans that are qualified under Section 401, 403, 408, 408A and 457 of the Code, individual retirement accounts (IRAs) and Roth IRAs. You should consult your tax advisor before investing in a fund.

PAYMENTS TO FINANCIAL ADVISORS

The financial advisor or intermediary through which you purchase your shares may receive all or a portion of the sales charges and distribution fees discussed above. In addition to those payments, Invesco Aim Distributors or one or more of its corporate affiliates (collectively, Invesco Aim Affiliates) may make additional cash payments to financial advisors in connection with the promotion and sale of shares of the funds. These additional cash payments may include cash payments and other payments for certain marketing and support services. Invesco Aim Affiliates make these payments from their own resources, from Invesco Aim Distributors' retention of initial sales charges and from payments to Invesco Aim Distributors made by the funds under their 12b-1 plans. In this context, "financial advisors" include any broker, dealer, bank (including bank trust departments), registered investment advisor, financial planner, retirement plan administrator and any other financial intermediary having a selling, administration or similar agreement with Invesco Aim Affiliates.

Invesco Aim Affiliates make payments as incentives to certain financial advisors to promote and sell shares of the funds. The benefits Invesco Aim Affiliates receive when they make these payments include, among other things, placing the funds on the financial advisor's funds sales system, and access (in some cases on a preferential basis over other competitors) to individual members of the financial advisor's sales force or to the financial advisor's management. These payments are sometimes referred to as "shelf space" payments because the payments compensate the financial advisor for including the funds in its fund sales system (on its "sales shelf"). Invesco Aim Affiliates compensate financial advisors differently depending typically on the level and/or type of considerations provided by the financial advisor. The payments Invesco Aim Affiliates make may be calculated based on sales of shares of the funds (Sales-Based Payments), in which case the total amount of such payments shall not exceed 0.25% of the public offering price of all shares sold by the financial advisor during the particular period. Payments may also be calculated based on the average daily net assets of the applicable funds attributable to that particular financial advisor (Asset-Based Payments), in which case the total amount of such cash payments shall not exceed 0.25% per annum of those assets during a defined period. Sales-Based Payments primarily create incentives to make new sales of shares of the funds and Asset-Based Payments primarily create incentives to retain previously sold shares of the funds in investor accounts. Invesco Aim Affiliates may pay a financial advisor either or both Sales-Based Payments and Asset-Based Payments.

Invesco Aim Affiliates are motivated to make these payments as they promote the sale of fund shares and the retention of those investments by clients of financial advisors. To the extent financial advisors sell more shares of the funds or retain shares of the funds in their clients' accounts, Invesco Aim Affiliates benefit from the incremental management and other fees paid to Invesco Aim Affiliates by the funds with respect to those assets.

Invesco Aim Affiliates also may make payments to certain financial advisors for certain administrative services, including record keeping and sub-accounting of shareholder accounts pursuant to a sub-transfer agency, omnibus account service or sub-accounting agreement. All fees payable by Invesco Aim Affiliates under this category of services are charged back to the funds, subject to certain limitations approved by the Board.

You can find further details in the fund's Statement of Additional Information about these payments and the services provided by financial advisors. In certain cases these payments could be significant to the financial advisor. Your financial advisor may charge you additional fees or commissions other than those disclosed in this prospectus. You can ask your financial advisor about any payments it receives from Invesco Aim Affiliates or the funds, as well as about fees and/or commissions it charges.

EXCESSIVE SHORT-TERM TRADING ACTIVITY (MARKET TIMING) DISCLOSURES

While the funds provide their shareholders with daily liquidity, their investment programs are designed to serve long-term investors and are not designed to accommodate excessive short-term trading activity in violation of our policies described below. Excessive short-term trading activity in the funds' shares (i.e., a purchase of fund shares followed shortly thereafter by a redemption of such shares, or vice versa) may hurt the long-term performance of certain funds by requiring them to maintain an excessive amount of cash or to liquidate portfolio holdings at a disadvantageous time, thus interfering with the efficient management of such funds by causing them to incur increased brokerage and administrative costs. Where excessive short-term trading activity seeks to take advantage of arbitrage opportunities from stale prices for portfolio securities, the value of fund shares held by long-term investors may be diluted. The Board has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares for all funds except the money market funds. However, there is the risk that these funds' policies and procedures will prove ineffective in whole or in part to detect or prevent excessive or short-term trading. These funds may alter their policies at any time without prior notice to shareholders if the advisor believes the change would be in the best interests of long-term shareholders.

The Invesco Aim Affiliates currently use the following tools designed to discourage excessive short-term trading in the retail funds:

- Trade activity monitoring.

- Trading guidelines.

- Redemption fees on trades in certain funds.

- The use of fair value pricing consistent with procedures approved by the Board.

Each of these tools is described in more detail below. Although these tools are designed to discourage excessive short-term trading, you should understand that none of these tools alone nor all of them taken together eliminate the possibility that excessive short-term trading activity in the funds will occur. Moreover, each of these tools involves judgments that are inherently subjective. Invesco Aim Affiliates seek to make these judgments to the best of their abilities in a manner that they believe is consistent with long-term shareholder interests.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the funds which differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

Money Market Funds. The Board of AIM Money Market Fund, AIM Tax-Exempt Cash Fund, Premier Portfolio, Premier Tax-Exempt Portfolio and Premier U.S. Government Money Portfolio (the money market funds) have not adopted any policies and procedures that would limit frequent purchases and redemptions of such funds' shares. The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions, and determined that those risks were minimal. Nonetheless, to the extent that a money market fund must maintain additional cash and/or securities with short-term durations in greater amounts than may otherwise be required or borrow to honor redemption requests, the money market fund's yield could be negatively impacted.

The Board does not believe that it is appropriate to adopt any such policies and procedures for the money market funds for the following reasons:

- The money market funds are offered to investors as cash management vehicles; investors must perceive an investment in such funds as an alternative to cash, and must be able to purchase and redeem shares regularly and frequently.

- One of the advantages of a money market fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of the money market funds will be detrimental to the continuing operations of such funds.

- The money market funds' portfolio securities are valued on the basis of amortized cost, and such funds seek to maintain a constant net asset value. As a result, there are no price arbitrage opportunities.

- Because the money market funds seek to maintain a constant net asset value, investors expect to receive upon redemption the amount they originally invested in such funds. Imposition of redemption fees would run contrary to investor expectations.

AIM Limited Maturity Treasury Fund. The Board of AIM Limited Maturity Treasury Fund has not adopted any policies and procedures that would limit frequent purchases and redemptions of such fund's shares. The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions and determined that those risks were minimal. Nonetheless, to the extent that AIM Limited Maturity Treasury Fund must maintain additional cash and/or securities with short-term durations in greater amounts than may otherwise be required or borrow to honor redemption requests, AIM Limited Maturity Treasury Fund's yield could be negatively impacted.

The Board does not believe that it is appropriate to adopt any such policies and procedures for the fund for the following reasons:

A-14

THE AIM FUNDS

- Many investors use AIM Limited Maturity Treasury Fund as a short-term investment alternative and should be able to purchase and redeem shares regularly and frequently.

- One of the advantages of AIM Limited Maturity Treasury Fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of AIM Limited Maturity Treasury Fund will be detrimental to the continuing operations of such fund.

TRADE ACTIVITY MONITORING
Invesco Aim Affiliates monitor selected trades on a daily basis in an effort to detect excessive short-term trading activities. If, as a result of this monitoring, Invesco Aim Affiliates believe that a shareholder has engaged in excessive short-term trading, they will seek to act in a manner that they believe is consistent with the best interests of long-term investors, which may include taking steps such as (i) asking the shareholder to take action to stop such activities or (ii) refusing to process future purchases or exchanges related to such activities in the shareholder's accounts other than exchanges into a money market fund. Invesco Aim Affiliates will use reasonable efforts to apply the fund's policies uniformly given the practical limitations described above.

The ability of Invesco Aim Affiliates to monitor trades that are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent.

TRADING GUIDELINES

If you exceed four exchanges out of a fund per calendar year (other than the money market funds and AIM Limited Maturity Treasury Fund), or a fund or an Invesco Aim Affiliate determines, in its sole discretion, that your short-term trading activity is excessive (regardless of whether or not you exceed such guidelines), it may, in its discretion, reject any additional purchase and exchange orders.

The ability of Invesco Aim Affiliates to monitor exchanges made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent. If shares of the funds are held in the name of a conduit investment vehicle and not in the names of the individual investors who have invested in the funds through the conduit investment vehicle, the conduit investment vehicle may be considered an individual shareholder of the funds. To the extent that a conduit investment vehicle is considered an individual shareholder of the funds, the funds are likely to be limited in their ability to impose exchange limitations on individual transactions initiated by investors who have invested in the funds through the conduit investment vehicle.

REDEMPTION FEES

You may be charged a 2% redemption fee if you redeem, including redeeming by exchange, shares of certain funds within 31 days of purchase. The ability of a fund to assess a redemption fee on redemptions effectuated through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent.

FAIR VALUE PRICING

Securities owned by a fund are to be valued at current market value if market quotations are readily available. All other securities and assets of a fund for which market quotations are not readily available are to be valued at fair value determined in good faith using procedures approved by the Board. Fair value pricing may reduce the ability of frequent traders to take advantage of arbitrage opportunities resulting from potentially "stale" prices of portfolio holdings. However, it cannot eliminate the possibility of frequent trading.

HIGH INCOME MUNICIPAL - TAX-FREE INTERMEDIATE

RISK/RETURN SUMMARY

AIM HIGH INCOME MUNICIPAL FUND (HIGH INCOME MUNICIPAL)

INVESTMENT OBJECTIVE

The fund's investment objective is to achieve a high level of current income that is exempt from federal income taxes.

PRIMARY INVESTMENT STRATEGIES

The fund will invest, normally, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in municipal debt securities that (1) pay interest which is excluded from gross income for federal income tax purposes, and (2) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax.

The fund invests, normally, at least 80% of its assets in municipal debt securities that are rated BBB/Baa or lower by Standard & Poor's Ratings Services, Moody's Investors Service, Inc., or any other nationally recognized statistical rating organization (NRSRO), or are deemed by the portfolio managers to be of comparable quality to such rated securities. The fund may invest all of its assets in debt securities that are rated BB/Ba or lower by an NRSRO, or are determined by the portfolio managers to be of comparable quality to such rated securities. It may also invest up to 10% of its assets in defaulted securities. Securities rated BB/Ba or lower are below investment grade quality and are commonly known as "junk bonds." The portfolio managers seek to maintain an average credit quality of BB/Ba on the fund's portfolio.

In selecting securities for the fund's portfolio, the portfolio managers focus on municipal securities they believe have favorable prospects for high current income.

Please see "Investment Objectives, Strategies and Risks" for additional information regarding the fund's investment strategies.

PRINCIPAL RISKS

Among the principal risks of investing in the fund, which could adversely affect its net asset value, yield and total return are:

Market Risk           High Yield Risk              Concentration Risk           Synthetic Municipal Securities Risk
Interest Rate Risk    Reinvestment Risk            Defaulted Securities Risk    Leverage Risk
Credit Risk           Municipal Securities Risk    Derivatives Risk             Management Risk

Please see "Investment Objectives, Strategies and Risks" for a description of these risks.

There is a risk that you could lose all or a portion of your investment in the fund and that the income you may receive from your investment may vary. The value of your investment in the fund will rise and fall with the prices of the securities in which the fund invests. An investment in the fund is not a deposit in a bank and is not insured guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.

AIM TAX-FREE INTERMEDIATE FUND (TAX-FREE INTERMEDIATE)

INVESTMENT OBJECTIVE

The fund's investment objective is to generate as high a level of tax-exempt income as is consistent with preservation of capital.

PRIMARY INVESTMENT STRATEGIES

The fund will invest, normally, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in municipal debt securities that (1) pay interest that is excluded from gross income for federal income tax purposes, and (2) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. At the present time, the fund will not invest in municipal debt securities if the interest on such securities is subject to the federal alternative minimum tax.

The fund intends to invest at least 80% of its assets in municipal debt securities determined to be of investment grade quality. Up to 20% of the fund's assets may be invested in municipal debt securities that are determined to be below investment grade quality. These types of securities are commonly known as "junk bonds."

In selecting securities for the fund's portfolio, the portfolio managers focus on municipal securities they believe have favorable prospects for high current income.

The portfolio managers seek to maintain a dollar-weighted average portfolio maturity for the fund of between three and ten years.

Please see "Investment Objectives, Strategies and Risks" for additional information regarding the fund's investment strategies.

PRINCIPAL RISKS

Among the principal risks of investing in the fund, which could adversely affect its net asset value, yield and total return are:

Market Risk           High Yield Risk              Concentration Risk                     Leverage Risk
Interest Rate Risk    Reinvestment Risk            Derivatives Risk                       Management Risk
Credit Risk           Municipal Securities Risk    Synthetic Municipal Securities Risk

Please see "Investment Objectives, Strategies and Risks" for a description of these risks.

There is a risk that you could lose all or a portion of your investment in the fund and that the income you may receive from your investment may vary. The value of your investment in the fund will rise and fall with the prices of the securities in which the fund invests.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown, and after-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

(1) Since Inception performance is only provided for a class with less than ten calendar years of performance.
(2) The return shown for the one year period is the historical performance of the fund's Institutional Class shares. The returns shown for other periods are the blended returns of the historical performance of the fund's Institutional Class shares since their inception and the restated historical performance of the fund's Class A shares (for the periods prior to inception of the Institutional Class shares) at net asset value. The inception date shown in the table is that of the fund's Class A shares. The inception date of the fund's Institutional Class shares is July 31, 2006.
(3) The Lehman Brothers Municipal Bond Index covers municipal bonds with a minimum credit rating of Baa, an outstanding par value of at least $5 million and issued as a part of a transaction of at least $50 million USD. The bonds must have been issued after December 31, 1990, and have a remaining maturity of at least one year.

(4) The fund has also included the Lehman Brothers High Yield Municipal Bond Index, which the fund believes more closely reflects the performance of the types of securities in which the fund invests. In addition, the Lipper High Yield Municipal Debt Funds Index (which may or may not include the fund) is included for comparison to a peer group.

(5) The Lehman Brothers High Yield Municipal Bond Index includes bonds that are non-rated or rated Ba1 or below. They must have an outstanding par value of at least $3 million and be issued as part of a transaction of at least $20 million. The bonds must have a dated-date after December 31, 1990 and must be at least one year from their maturity date.

(6) The Lipper High Yield Municipal Debt Funds Index is an equally weighted representation of the largest funds in the Lipper High Yield Municipal Debt Funds category. These funds invest at least 50% of their assets in lower rated municipal debt issues.

(7) The return shown for the one year period is the historical performance of the fund's Institutional Class shares. The returns shown for other periods are the blended returns of the historical performance of the fund's Institutional Class shares since their inception and the restated historical performance of the fund's Class A shares (for the periods prior to the inception of the Institutional Class shares) at the net asset value. The inception date shown in the table is that of the fund's Class A shares. The inception date of the fund's Institutional Class shares is July 30, 2004.

(8) The fund has also included the Merrill Lynch 3-7 Year Municipal Index, which the fund believes more closely reflects the performance of the types of securities in which the fund invests. In addition, the Lipper Intermediate Municipal Debt Funds Index (which may or may not include the fund) is included for comparison to a peer group.

(9) The Merrill Lynch 3-7 Year Municipal Index is a domestic bond index that holds municipal bonds with maturities that range between three and seven years.

(10) The Lipper Intermediate Municipal Debt Funds Index is an equally weighted representation of the largest funds in the Lipper Intermediate Municipal Debt Funds category. These funds invest in municipal debt issues with dollar-weighted average maturities of five to ten years.

(11) The average annual total return given is since the month-end closest to the inception date of the class with the longest performance history.

(1) There is no guarantee that actual expenses will be the same as those shown in the table.
(2) Effective May 1, 2008, High Income Municipal's investment advisor has voluntarily agreed to waive advisory fees and/or reimburse expenses to the extent necessary to limit Total Annual Fund Operating Expenses (excluding certain items discussed below) of Institutional Class shares of High Income Municipal to 0.50% of average daily net assets. In determining the advisor's obligation to waive advisory fees and/or reimburse expenses, the following expenses are not taken into account, and could cause the Net Annual Fund Operating Expenses to exceed the numbers reflected above: (i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary items; (v) expenses related to a merger or reorganization, as approved by the fund's Board of Trustees; and (vi) expenses that the fund has incurred but did not actually pay because of an expense offset arrangement. Currently, in addition to the expense reimbursement arrangement with Invesco Ltd., the expense offset arrangements from which the fund may benefit are in the form of credits that the fund receives from banks where the fund or its transfer agent has deposit accounts in which it holds uninvested cash. Those credits are used to pay certain expenses incurred by the fund. Voluntary fee waivers or reimbursements may be modified or discontinued at any time upon consultation with the Board of Trustees without further notice to investors.

If a financial institution is managing your account, you may also be charged a transaction or other fee by such financial institution.

EXPENSE EXAMPLE
This example is intended to help you compare the cost of investing in different classes the funds with the cost of investing in other mutual funds.

The expense example assumes you:
(i) invest $10,000 in the fund for the time periods indicated;
(ii) redeem all of your shares at the end of the periods indicated;
(iii) earn a 5% return on your investment before operating expenses each year; and
(iv) incur the same amount in operating expenses each year (after giving effect to any applicable contractual fee waivers and/or expense reimbursements).

To the extent fees are waived and/or expenses are reimbursed voluntarily, your expenses will be lower. Although your actual returns and costs may be higher or lower, based on these assumptions your costs would be:

HYPOTHETICAL INVESTMENT AND EXPENSE INFORMATION

The settlement agreement between Invesco Aim Advisors, Inc. and certain of its affiliates and the New York Attorney General requires Invesco Aim Advisors, Inc. and certain of its affiliates to provide certain hypothetical information regarding investment and expense information. The chart below is intended to reflect the annual and cumulative impact of the funds' expenses, including investment advisory fees and other fund costs, on the funds' return over a 10- year period. The example reflects the following:
- You invest $10,000 in a fund and hold it for the entire 10 year period; and
- Your investment has a 5% return before expenses each year.

There is no assurance that the annual expense ratio will be the expense ratio for the funds' Institutional Classes for any of the years shown. To the extent that Invesco Aim Advisors, Inc. and certain of its affiliates make any fee waivers and/or expense reimbursements pursuant to a voluntary arrangement, your actual expenses may be less. This is only a hypothetical presentation made to illustrate what expenses and returns would be under the above scenarios; your actual returns and expenses are likely to differ (higher or lower) from those shown below.

INVESTMENT OBJECTIVES, STRATEGIES AND RISKS

OBJECTIVES AND STRATEGIES

HIGH INCOME MUNICIPAL

The fund's investment objective is to achieve a high level of current income that is exempt from federal income taxes. The fund's investment objective may be changed by the Board of Trustees without shareholder approval.

The fund seeks to meet its investment objective by investing, normally, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in municipal debt securities that (1) pay interest which is excluded from gross income for federal income tax purposes, and (2) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. The fund may invest up to 20% of its total assets in taxable securities.

The principal type of municipal debt securities purchased by the fund are municipal bonds, which include revenue bonds and general obligation bonds.

Municipal debt securities include debt obligations of states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies, and instrumentalities, authorities thereof, and multi-state agencies, issued to obtain funds for various public purposes. Synthetic municipal securities, which include variable rate instruments that are created when fixed rate bonds are coupled with a third party tender feature and variable tender fees are treated as municipal debt securities. Other securities held by the fund may be structured with demand features which have the effect of shortening the security's maturity.

The fund invests, normally, at least 80% of its assets in municipal debt securities that are rated BBB/Baa or lower by Standard & Poor's Ratings Services, Moody's Investors Service, Inc., or any other nationally recognized statistical rating organization (NRSRO), or are deemed by the portfolio managers to be of comparable quality to such rated securities. The fund may invest all of its assets in debt securities that are rated BB/Ba or lower by an NRSRO, or are determined by the portfolio managers to be of comparable quality to such rated securities. It may also invest up to 10% of its assets in defaulted securities. Securities rated BB/Ba or lower are below investment grade quality and are commonly known as "junk bonds." The portfolio managers seek to maintain an average credit quality of BB/Ba on the fund's portfolio.

The fund may invest 25% or more of its assets in municipal securities issued by entities having similar characteristics, such as (a) securities the issuers of which are located in the same geographic area or securities where issuers' interest obligations are paid from revenues of similar

HIGH INCOME MUNICIPAL - TAX-FREE INTERMEDIATE

INVESTMENT OBJECTIVES, STRATEGIES AND RISKS (continued)

projects, or (b) industrial development revenue bonds, including pollution control revenue bonds, housing finance agency bonds or hospital bonds. The fund may not, however, invest 25% or more of its total assets in industrial development revenue bonds, including pollution control revenue bonds, issued for companies in the same industry. The fund may, but does not currently intend to, invest 25% or more of its total assets in securities whose issuers are located in any of the following states: Arizona, California, Colorado, Connecticut, Florida, Illinois, Michigan, Massachusetts, New Hampshire, New Jersey, New York, Ohio, Pennsylvania and Texas.

The fund's investments in the types of securities described in this prospectus vary from time to time, and, at any time, the fund may not be invested in all types of securities described in this prospectus. Any percentage limitations with respect to assets of the fund are applied at the time of purchase.

The portfolio managers generally take a buy and hold approach while focusing on municipal securities they believe have favorable prospects for high current income. Many of the municipal securities in which the fund invests, such as revenue bonds, are typically issued by a public authority and the proceeds from such securities are used to build or renovate a specific project, such as an airport, a toll road, water and sewer works, hospitals or housing. The proceeds from the project--such as rents, tolls or user fees--are used to pay interest and principal on the municipal securities. Another type of municipal security in which the fund invests in are general obligation bonds. These bonds are repaid from a municipality's general revenues and are generally backed by the full faith and credit of the municipal issuer.

In selecting securities for the fund's portfolio, the portfolio managers initially focus on experienced project managers, as well as projects that the portfolio managers believe make good economic and business sense. Prior to investing in a municipal security, the portfolio managers and/or fund analysts generally: (i) review the industry and project financial statements, (ii) perform site visits to talk with management about the project and facility,
(iii) review independent appraisals of the project, (iv) review environmental and feasibility studies on the project, and (v) conduct cash flow analysis. Before purchasing a municipal security upon its initial issuance, the portfolio managers or analysts may negotiate key terms, such as calls and loan covenants, credit basis, and a fair price (coupon) for the municipal security. Following an investment in a municipal security, the portfolio managers or analysts normally maintain phone contact with project managers, make periodic site visits to determine it the project is likely to reach its goals, and review monthly and quarterly statements.

The portfolio managers consider selling a security: (i) if the issuer's credit quality declines, (ii) if the outlook for a project undergoes a negative change, (iii) to shorten or lengthen the fund's duration (a measure of the fund's price sensitivity to changes in interest rates), (iv) as a result of interest rate changes, or (v) to limit exposure to a sector or issuer.

The fund typically maintains a portion of its assets in cash, cash equivalents, high quality debt instruments, and/or money market funds advised by the fund's advisor. Depending upon the then-current investment environment, holding a relatively larger percentage of portfolio assets in such instruments may either assist or hinder the fund's relative performance and its ability to achieve its investment objective. The fund holds cash to handle its daily cash needs, which include payment of fund expenses, redemption requests and securities transactions. In order to respond to adverse market, economic or other conditions, the fund may assume a temporary defensive position and invest a relatively larger percentage of the fund's portfolio assets in cash, cash equivalents or high quality debt instruments.

TAX-FREE INTERMEDIATE

The fund's investment objective is to generate as high a level of tax-exempt income as is consistent with preservation of capital. The fund's investment objective may be changed by the Board of Trustees without shareholder approval.

The fund will invest, normally, at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in municipal debt securities that (1) pay interest that is excluded from gross income for federal income tax purposes, and (2) do not produce income that will be considered to be an item of preference for purposes of the alternative minimum tax. In complying with this 80% investment requirement, the fund's investments may include synthetic instruments that in the judgment of the fund's advisor have economic characteristics similar to the fund's direct investments. At the present time, the fund will not invest in municipal debt securities if the interest on such securities is subject to the federal alternative minimum tax.

The principal type of municipal debt securities purchased by the fund are municipal bonds, which include revenue bonds and general obligation bonds.

Municipal debt securities include debt obligations of states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies, and instrumentalities, authorities thereof, and multi-state agencies, issued to obtain funds for various public purposes. Municipal lease obligations, synthetic municipal securities and industrial development bonds are treated as municipal debt securities.

At least 80% of the fund's assets will normally be invested in municipal debt securities that are determined to be of investment grade quality, because they meet one of the following quality criteria at the time of purchase: (1) securities rated within the four highest ratings for long-term municipal obligations by Moody's Investors Service, Inc. (Moody's), Standard & Poor's Ratings Services (S&P) or any other nationally recognized statistical rating organization (NRSRO); (2) (a) securities rated within the three highest ratings for short-term municipal obligations by Moody's, or (b) securities rated within the two highest ratings for short-term municipal obligations by S&P, or (c) securities deemed by the portfolio managers to be of comparable quality to the securities set forth in 2(a) or 2(b); (3) securities guaranteed as to payment of principal and interest by the U.S. Government; (4) securities fully collateralized by an escrow of U.S. Government or other high-quality securities; or (5) unrated

INVESTMENT OBJECTIVES, STRATEGIES AND RISKS (continued)

securities, if (a) other municipal securities of the same issuer are rated BBB or better by an NRSRO, or (b) they are deemed by the portfolio managers to be of comparable quality.

Up to 20% of the fund's assets may be invested in municipal debt securities that are determined to be below investment grade quality because they are rated BB or lower by an NRSRO, or are determined by a portfolio manager to be of comparable quality to such rated securities. These types of securities are commonly known as "junk bonds." The amount of the fund's investments in these types of securities varies from time to time but will not exceed more than 20% of the fund's assets.

The fund's investments in the types of securities described in this prospectus vary from time to time, and, at any time, the fund may not be invested in all types of securities described in this prospectus. Any percentage limitations with respect to assets of the fund are applied at the time of purchase.

In constructing the fund's portfolio, the portfolio managers attempt to control price volatility by purchasing bonds trading at a premium to par, which bonds generally have less price volatility than bonds trading at a discount.

The fund will attempt to maintain a dollar-weighted average portfolio maturity of between three and ten years. The portfolio managers determine which municipal bond sectors have compelling value and what maturities are needed in order to maintain the fund's duration (a measure of the fund's price sensitivity to changes in interest rates). The portfolio managers may, from time to time, shorten or lengthen the duration of the fund's portfolio to protect principal in the event of rising or falling interest rates.

The portfolio managers normally hold municipal bonds to maturity. The portfolio managers consider selling a security: (i) if the issuer's credit quality declines, (ii) to shorten or lengthen the fund's duration, (iii) as a result of interest rate changes, or (iv) to limit exposure to a sector or issuer.

The fund typically maintains a portion of its assets in cash, cash equivalents, high quality debt instruments, and/or money market funds advised by the fund's advisor. Depending upon the then-current investment environment, holding a relatively larger percentage of portfolio assets in such instruments may either assist or hinder the fund's relative performance and its ability to achieve its investment objective. The fund holds cash to handle its daily cash needs, which include payment of fund expenses, redemption requests and securities transactions. In order to respond to adverse market, economic or other conditions, the fund may assume a temporary defensive position and invest a relatively larger percentage of the fund's portfolio assets in cash, cash equivalents or high quality debt instruments.

RISKS

HIGH INCOME MUNICIPAL

The principal risks of investing in the fund are:

Market Risk--The prices of and the income generated by securities held by the fund may decline in response to certain events, including those directly involving the issuers, or in the case of industrial development revenue bonds, the company for whose benefit the bonds are being issued; general economic and market conditions; regional or global economic instability; and interest rate fluctuations.

Interest Rate Risk--Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on specific characteristics of each bond.

Credit Risk--Credit risk is the risk of loss on an investment due to the deterioration of an issuer's financial health. Such a deterioration of financial health may result in a reduction of the credit rating of the issuer's securities and may lead to the issuer's inability to honor its contractual obligations including making timely payment of interest and principal. Credit ratings are a measure of credit quality. Although a downgrade or upgrade of a bond's credit ratings may or may not affect its price, a decline in credit quality may make bonds less attractive, thereby driving up the yield on the bond and driving down the price. Declines in credit quality may result in bankruptcy for the issuer and permanent loss of investment. Revenue bonds are generally not backed by the taxing power of the issuing municipality and therefore are subject to a higher degree of credit risk than general obligation bonds.

High Yield Risk--High yield risk is a form of credit risk. High yield bonds or "junk bonds" are bonds rated below investment grade or deemed to be of comparable quality. They are considered to be speculative investments with greater risk of failure to make timely payment of interest and principal (to default on their contractual obligations) than their investment grade counterparts. High yield bonds may exhibit increased price sensitivity and reduced liquidity generally and particularly during times economic downturn or volatility in the capital markets.

Reinvestment Risk--Reinvestment risk is the risk that a bond's cash flows (coupon income and principal repayment) will be reinvested at an interest rate below that on the original bond. If interest rates decline, the underlying bond may rise in value, but the cash flows received from that bond may have to be invested at a lower interest rate.

Municipal Securities Risk--The value of, payment of interest and repayment of principal with respect to, and the ability of the fund to sell, a municipal security may be affected by constitutional amendments, legislative enactments, executive orders, administrative regulations and voter initiatives as well as the economics of the regions in which the issuers in which the fund invests are located. Municipal securities backed by current or anticipated revenues from a specific project or assets, such as revenue bonds, can be negatively affected by the discontinuance of the taxation supporting the project or assets or the inability to collect revenues for the project or from the assets. If the Internal Revenue Service determines that an issuer of a municipal security has not complied with applicable tax requirements, interest from the security could be treated

INVESTMENT OBJECTIVES, STRATEGIES AND RISKS (continued)

as taxable, which could result in a decline in the security's value. To the extent that a municipal security in which the fund invests is not heavily followed by the investment community or such security issue is relatively small, the security may be difficult to value or sell at a fair price.

Concentration Risk--Because many municipal securities are issued to finance similar projects, especially those relating to education, health care, transportation and utilities, conditions in those sectors can affect the overall municipal securities market and the fund. Moreover, sizeable investments in securities issued to finance similar projects could involve an increased risk to the fund if economic or other factors adversely affect the viability of these projects.

Defaulted Securities Risk--The fund may invest in securities where the issuer has defaulted on the payment of interest and/or principal. Defaulted securities are speculative and involve substantial risks. Generally, the fund will invest in defaulted securities when the portfolio managers believe they offer significant potential for higher returns or can be exchanged for other securities that offer this potential. There can be no assurance that the fund will achieve these returns or that the issuer will make an exchange offer. The fund will generally not receive interest payments on defaulted securities and may incur costs to protect its investment. In addition, defaulted securities involve the substantial risk that principal will not be repaid. Defaulted securities and any securities received in an exchange for such securities may be subject to restrictions on resale.

Derivatives Risk--The value of "derivatives" or "synthetics"--so called because their value "derives" from the value of an underlying asset (including an underlying security), reference rate or index--may rise or fall more rapidly than other investments. For some derivatives, it is possible to lose more than the amount invested in the derivative. Derivatives may be used to create synthetic exposure to an underlying asset or to hedge portfolio risk. If the fund uses derivatives to "hedge" a portfolio risk, it is possible that the hedge may not succeed. This may happen for various reasons, including unexpected changes in the value of the rest of the fund's portfolio. Over the counter derivatives are also subject to counterparty risk, which is the risk that the other party to the contract will not fulfill its contractual obligations to complete the transaction with the fund.

Synthetic Municipal Securities Risk--The tax-exempt character of the interest paid on synthetic municipal securities is based on the tax-exempt income stream from the collateral. The Internal Revenue Service has not ruled on this issue and could deem income derived from synthetic municipal securities to be taxable.

Leverage Risk--If the fund borrows money to finance investments, it is engaging in a practice known as "leveraging." If the prices of those investments decrease, or if the cost of borrowing exceeds any increases in the prices of those investments, the net asset value of the fund's shares will decrease faster than if the fund had not used leverage. To repay borrowings, the fund may have to sell investments at a time and at a price that is unfavorable to the fund. Interest on borrowings is an expense the fund would not otherwise incur. There can be no assurance that the fund will use leverage or should the fund use leverage, that the fund's leverage strategy will be successful.

Management Risk--There is no guarantee that the investment techniques and risk analyses used by the fund's portfolio manager(s) will produce the desired results.

TAX-FREE INTERMEDIATE

The principal risks of investing in the fund are:

Market Risk--The prices of and the income generated by securities held by the fund may decline in response to certain events, including those directly involving the issuers, or in the case of industrial development revenue bonds, the company for whose benefit the bonds are being issued; general economic and market conditions; regional or global economic instability; and interest rate fluctuations.

Interest Rate Risk--Interest rate risk refers to the risk that bond prices generally fall as interest rates rise; conversely, bond prices generally rise as interest rates fall. Specific bonds differ in their sensitivity to changes in interest rates depending on specific characteristics of each bond.

Credit Risk--Credit risk is the risk of loss on an investment due to the deterioration of an issuer's financial health. Such a deterioration of financial health may result in a reduction of the credit rating of the issuer's securities and may lead to the issuer's inability to honor its contractual obligations including making timely payment of interest and principal. Credit ratings are a measure of credit quality. Although a downgrade or upgrade of a bond's credit ratings may or may not affect its price, a decline in credit quality may make bonds less attractive, thereby driving up the yield on the bond and driving down the price. Declines in credit quality may result in bankruptcy for the issuer and permanent loss of investment. Revenue bonds are generally not backed by the taxing power of the issuing municipality and therefore are subject to a higher degree of credit risk than general obligation bonds.

High Yield Risk--High yield risk is a form of credit risk. High yield bonds or "junk bonds" are bonds rated below investment grade or deemed to be of comparable quality.

OTHER INFORMATION

DIVIDENDS AND DISTRIBUTIONS

The funds expect that their distributions, if any, will consist primarily of income (most of which is expected to be exempt from federal income taxes).

DIVIDENDS

The funds generally declare dividends from net investment income on each business day and pay dividends, if any, monthly.

CAPITAL GAINS DISTRIBUTIONS

The funds generally distribute long-term and short-term capital gains, if any, annually, but may declare and pay capital gains distributions more than once per year as permitted by law. Capital gains distributions may vary considerably from year to year as a result of a fund's normal investment activities and cash flows.

LIMITED FUND OFFERING (HIGH INCOME MUNICIPAL)

Due to the sometimes limited availability of certain municipal securities that meet the portfolio managers' investment process for the fund, the fund limited public sales of its shares to new investors, effective as of the close of business on September 21, 2007. The advisor has determined that there is currently an ample supply of the types of securities in which the fund invests to permit the fund to re-open to all investors commencing with the start of business on March 3, 2008 through the earlier of the close of business on or about August 29, 2008 or when the fund reaches $800 million in assets. Investors should note that the fund reserves the right to refuse any order that might disrupt the efficient management of the fund.

All investors who are invested in the fund as of the date on which the fund closed to new investors and remain invested in the fund may continue to make additional investments in their existing accounts and may open new accounts in their name. Additionally, the following types of investors may be allowed to open a new account in the fund, subject to the approval of Invesco Aim Distributors and the advisor.

- Retirement plans maintained pursuant to Section 401 of the Internal Revenue Code (the Code);

- Retirement plans maintained pursuant to Section 403 of the Code, to the extent they are maintained by organizations established under Section 501(c)(3) of the Code;

- Non qualified deferred compensation plans maintained pursuant to Section 409A of the Code;

- Retirement plans maintained pursuant to Section 457 of the Code; and

- Qualified Tuition Programs maintained pursuant to Section 529 of the Code.

Future investments in the fund may also be made by or through brokerage firm wrap programs, subject to the approval of Invesco Aim Distributors and the advisor. Such plans and programs that are considering the fund as an investment option should contact Invesco Aim Distributors.

At the advisors' discretion, proprietary asset allocation funds may open new accounts in the fund. In addition, the fund's current portfolio managers and portfolio management team may also make investments in the fund.

11


HIGH INCOME MUNICIPAL - TAX-FREE INTERMEDIATE

OTHER INFORMATION (continued)

The fund, upon consultation with the Board of Trustees, may resume sales of shares to other new investors on a future date if the advisor determines it is appropriate.

SUITABILITY FOR INVESTORS

The Institutional Class of the funds are intended for use by institutional investors. Shares of the Institutional Class of the funds are available for banks and trust companies acting in a fiduciary or similar capacity, bank and trust company common and collective trust funds, banks and trust companies investing for their own account, entities acting for the account of a public entity (e.g. Taft-Hartley funds, states, cities or government agencies), defined benefit plans, endowments, foundations and defined contribution plans offered pursuant to Sections 401, 457, 403(a), or 403(b) or (c) (defined contribution plans offered pursuant to Section 403(b) must be sponsored by a Section 501(c)(3) organization). For defined contribution plans for which the sponsor has combined defined contribution and defined benefit assets of at least $100 million there is no minimum initial investment requirement, otherwise the minimum initial investment requirement for defined contribution plans is $10 million. There is no minimum initial investment requirement for defined benefit plans, and the minimum initial investment requirement for all other investors for which the Institutional Class of the fund is available is $1 million.

The Institutional Class of the funds are designed to be a convenient and economical vehicle in which institutions can invest in a portfolio of securities. An investment in the funds may relieve the institution of many of the investment and administrative burdens encountered when investing in securities directly. These include: selection and diversification of portfolio investments; surveying the market for the best price at which to buy and sell; valuation of portfolio securities; receipt, delivery and safekeeping of securities; and portfolio recordkeeping.

SPECIAL TAX INFORMATION REGARDING THE FUNDS

In addition to the general tax information set forth under the heading "General Information--Taxes" in this prospectus, the following information describes the tax impact of certain dividends you may receive from the funds:

- You will not be required to include the "exempt-interest" portion of dividends paid by the fund in your gross income for federal income tax purposes. You will be required to report the receipt of exempt-interest dividends and other tax-exempt interest on your federal income tax return.

- The fund may invest a portion of its assets in securities that pay income that is not tax-exempt. The fund also may distribute to you any market discount and net short-term capital gains from the sale of its portfolio securities. If you are a taxable investor, fund distributions from this income are taxable to you as ordinary income, and generally will neither qualify for the dividends received deduction in the case of corporate shareholders nor as qualified dividend income subject to reduced rates of taxation in the case of non- corporate shareholders.

- The funds may invest in municipal securities the interest on which constitutes an item of tax preference and could give rise to a federal alternative minimum tax liability for you, and may invest up to 20% of their net assets in such securities and other taxable securities. The funds will try to avoid investments that result in taxable dividends.

- Exempt-interest dividends from the fund are taken into account when determining the taxable portion of your social security of railroad retirement benefits, may be subject to state and local income taxes, may affect the deductibility of interest on certain indebtedness, and may have other collateral federal income tax consequences for you.

- The percentage of dividends that constitutes exempt-interest dividends will be determined annually. This percentage may differ from the actual percentage of exempt interest received by the funds for the particular days in which you hold shares.

- From time to time, proposals have been introduced before Congress that would have the effect of reducing or eliminating the federal tax exemption on municipal securities. If such a proposal were enacted, the ability of the funds to pay exempt-interest dividends might be adversely affected.

                        wire instructions specified in the account application
                        provided to the transfer agent. The transfer agent must
                        receive your financial advisor's or intermediary's call
                        before the close of the customary trading session of the

THE AIM FUNDS - INSTITUTIONAL CLASS

TIMING AND METHOD OF PAYMENT

We normally will send out redemption proceeds within one business day, and in any event no more than seven days, after your redemption request is received in good order (meaning that all necessary information and documentation related to the redemption request have been provided to the transfer agent). If your request is not in good order, we may require additional documentation in order to redeem your shares. Payment may be postponed in cases where the Securities and Exchange Commission (SEC) declares an emergency or normal trading is halted on the NYSE.

If you redeem by telephone, we will transmit the amount of redemption proceeds electronically to your pre-authorized bank account.

We use reasonable procedures to confirm that instructions communicated via telephone are genuine, and we are not liable for losses arising from actions taken in accordance with instructions that are reasonably believed to be genuine.

REDEMPTIONS IN KIND

Although the funds generally intend to pay redemption proceeds solely in cash, the funds reserve the right to determine in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind).

REDEMPTIONS INITIATED BY THE FUNDS

If the fund determines that you have not provided a correct Social Security or other tax ID number on your account application, or the fund is not able to verify your identity as required by law, the fund may, at its discretion, redeem the account and distribute the proceeds to you.

REDEMPTION FEES

Certain funds impose a 2% redemption fee (on redemption proceeds) if you redeem or exchange shares within 31 days of purchase. Please refer to the applicable fund's prospectus to determine whether that fund imposes a redemption fee. As of the date of this prospectus, the following funds impose redemption fees:

AIM China Fund
AIM Developing Markets Fund
AIM Floating Rate Fund
AIM Global Core Equity Fund
AIM Global Equity Fund
AIM Global Growth Fund
AIM Global Real Estate Fund
AIM Global Small & Mid Cap Growth Fund
AIM High Yield Fund
AIM International Allocation Fund
AIM International Core Equity Fund
AIM International Growth Fund
AIM International Small Company Fund
AIM International Total Return Fund
AIM Japan Fund
AIM Trimark Fund

The redemption fee will be retained by the fund from which you are redeeming or exchanging shares, and is intended to offset the trading costs, market impact and other costs associated with short-term money movements in and out of the fund. The redemption fee is imposed on a first-in, first-out basis which means that you will redeem shares in the order of their purchase.

Redemption fees generally will not be charged in the following circumstances:

- Redemptions and exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to assess the redemption fees.

- Redemptions and exchanges of shares held by funds of funds, qualified tuition plans maintained pursuant to Section 529 of the Code, variable insurance contracts or separately managed qualified default investment alternative vehicles maintained pursuant to Section 404(c)(5) of the Employee Retirement Income Security Act of 1974, as amended (ERISA), which use the funds as underlying investments.

- Redemptions and exchanges effectuated pursuant to an intermediary's automatic investment rebalancing or dollar cost averaging programs or systematic withdrawal plans.

- Redemptions requested within 31 days following the death or post-purchase disability of an account owner.

- Redemptions or exchanges initiated by a fund.

The following shares are not subject to redemption fees, irrespective of whether they are redeemed in accordance with any of the exceptions set forth above:

- Shares acquired through the reinvestment of dividends and distributions.

- Shares acquired in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan or individual retirement account (IRA) to the trustee or custodian of another employee benefit plan or IRA.

Shares held by employee benefit plans will only be subject to redemption fees if the shares were acquired by exchange and are redeemed by exchange within 31 days of purchase.

Some investments in the funds are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and some investments are made indirectly through products that use the funds as underlying investments, such as employee benefit plans, funds of funds, qualified tuition plans, and variable insurance contracts (these products are generally referred to as conduit investment vehicles). If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary account or conduit investment vehicle may be considered an individual shareholder of the funds for purposes of assessing redemption fees. In these cases, the funds are likely to be limited in their ability to assess redemption fees on transactions initiated by individual investors, and the applicability of redemption fees will be determined based on the aggregate holdings and redemptions of the intermediary account or the conduit investment vehicle.

If shares of the funds are held in an account maintained by an intermediary or in the name of a conduit investment vehicle (and not in the names of individual investors), the intermediary or conduit investment vehicle may impose rules intended to limit short-term money movements in and out of the

A-2

THE AIM FUNDS - INSTITUTIONAL CLASS

funds which
differ from those described in this prospectus. In such cases, there may be redemption fees imposed by the intermediary or conduit investment vehicle on different terms (and subject to different exceptions) than those set forth above. Please consult your financial advisor or other intermediary for details.

The funds have the discretion to waive the 2% redemption fee if a fund is in jeopardy of losing its registered investment company qualification for tax purposes.

Your financial advisor or other intermediary may charge service fees for handling redemption transactions.

EXCHANGING SHARES

You may, under most circumstances, exchange Institutional Class shares in one fund for Institutional Class shares of another fund. An exchange is the purchase of shares in one fund which is paid for with the proceeds from a redemption of shares of another fund effectuated on the same day. Before requesting an exchange, review the prospectus of the fund you wish to acquire.

All exchanges are subject to the limitations set forth in the prospectuses of the funds. If you wish to exchange shares of one fund for those of another fund, you must consult the prospectus of the fund whose shares you wish to acquire to determine whether the fund is offering shares to new investors and whether you are eligible to acquire shares of that fund.

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

- Shares must have been held for at least one day prior to the exchange with the exception of dividends and distributions that are reinvested; and

- If you have physical share certificates, you must return them to the transfer agent in order to effect the exchange.

Under unusual market conditions, a fund may delay the exchange of shares for up to five business days if it determines that it would be materially disadvantaged by the immediate transfer of exchange proceeds. The exchange privilege is not an option or right to purchase shares.

Any of the participating funds or the distributor may modify or terminate this privilege at any time. The fund or Invesco Aim Distributors, Inc.

("Invesco Aim Distributors") will provide you with notice of such modification or termination if it is required to do so by law.

LIMIT ON THE NUMBER OF EXCHANGES

You will generally be limited to four exchanges out of a fund per calendar year; provided, however, that the following transactions will not count toward the exchange limitation:

- Exchanges of shares held in accounts maintained by intermediaries that do not have the systematic capability to apply the exchange limitation.

- Exchanges of shares held by funds of funds and insurance company separate accounts which use the funds as underlying investments.

- Exchanges effectuated pursuant to automatic investment rebalancing or dollar cost averaging programs.

- Exchanges initiated by a fund or by the trustee, administrator or other fiduciary of an employee benefit plan (not in response to distribution or exchange instructions received from a plan participant).

- If you acquire shares in connection with a rollover or transfer of assets from the trustee or custodian of an employee benefit plan or IRA to the trustee or custodian of a new employee benefit plan or IRA, your first reallocation of those assets will not count toward the exchange limitation.

Each fund reserves the discretion to accept exchanges in excess of these guidelines on a case-by-case basis if the fund, or its designated agent, believes that granting such exceptions would be consistent with the best interests of shareholders.

If you exchange shares of one fund for shares of multiple other funds as part of a single transaction, that transaction is counted as one exchange out of a fund.

RIGHTS RESERVED BY THE FUNDS

Each fund and its agent reserves the right at any time to:

- Reject or cancel all or any part of any purchase or exchange order.

- Modify any terms or conditions related to the purchase, redemption or exchange of shares of any fund.

- Suspend, change or withdraw all or any part of the offering made by this Prospectus.

PAYMENTS TO FINANCIAL ADVISORS

Invesco Aim Distributors or one or more of its corporate affiliates (collectively, Invesco Aim Affiliates) may make cash payments to financial advisors in connection with the promotion and sale of shares of the funds. These cash payments may include cash payments and other payments for certain marketing and support services. Invesco Aim Affiliates make these payments from their own resources. In this context, "financial advisors" include any broker, dealer, bank (including bank trust departments), registered investment advisor, financial planner, retirement plan administrator and any other financial intermediary having a selling, administration or similar agreement with Invesco Aim Affiliates.

Invesco Aim Affiliates make payments as incentives to certain financial advisors to promote and sell shares of the funds. The benefits Invesco Aim Affiliates receive when they make these payments include, among other things, placing the fund on the financial advisor's funds sales system, and access (in some cases on a preferential basis over other competitors) to individual members of the financial advisor's sales force or to the financial advisor's management. These payments are sometimes referred to as "shelf space" payments because the payments compensate the financial advisor for including the funds in its fund sales system (on its "sales shelf"). Invesco Aim Affiliates compensate financial advisors differently depending typically on

A-3

THE AIM FUNDS - INSTITUTIONAL CLASS

the level and/or type of considerations provided by the financial advisor. The payments Invesco Aim Affiliates make may be calculated based on sales of shares of the funds (Sales-Based Payments), in which case the total amount of such payments shall not exceed 0.10% of the public offering price of all shares sold by the financial advisor during the particular period. Payments may also be calculated based on the average daily net assets of the applicable funds attributable to that particular financial advisor (Asset-Based Payments), in which case the total amount of such cash payments shall not exceed 0.25% per annum of those assets during a defined period. Sales-Based Payments primarily create incentives to make new sales of shares of the funds and Asset-Based Payments primarily create incentives to retain previously sold shares of the funds in investor accounts. Invesco Aim Affiliates may pay a financial advisor either or both Sales-Based Payments and Asset-Based Payments.

Invesco Aim Affiliates are motivated to make these payments as they promote the sale of fund shares and the retention of those investments by clients of financial advisors. To the extent financial advisors sell more shares of the funds or retain shares of the funds in their clients' accounts, Invesco Aim Affiliates benefit from the incremental management and other fees paid to Invesco Aim Affiliates by the funds with respect to those assets.

Invesco Aim Affiliates also may make payments to certain financial advisors for certain administrative services, including record keeping and sub-accounting of shareholder accounts pursuant to a sub-transfer agency or sub-accounting agreement. All fees payable by Invesco Aim Affiliates under this category of services are charged back to the funds, subject to certain limitations approved by the funds' Boards of Trustees (collectively, the Board).

You can find further details in the fund's Statement of Additional Information about these payments and the services provided by financial advisors. In certain cases these payments could be significant to the financial advisor. Your financial advisor may charge you additional fees or commissions other than those disclosed in this prospectus. You can ask your financial advisor about any payments it receives from Invesco Aim Affiliates or the funds, as well as about fees and/or commissions it charges.

EXCESSIVE SHORT-TERM TRADING ACTIVITY (MARKET TIMING) DISCLOSURES

While the funds provide their shareholders with daily liquidity, their investment programs are designed to serve long-term investors and are not designed to accommodate excessive short-term trading activity in violation of our policies described below. Excessive short-term trading activity in the funds' shares (i.e., a purchase of fund shares followed shortly thereafter by a

redemption of such shares, or vice versa) may hurt the long-term performance of certain funds by requiring them to maintain an excessive amount of cash or to liquidate portfolio holdings at a disadvantageous time, thus interfering with the efficient management of such funds by causing them to incur increased brokerage and administrative costs. Where excessive short-term trading activity seeks to take advantage of arbitrage opportunities from stale prices for portfolio securities, the value of fund shares held by long-term investors may be diluted. The Board has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares for all funds. However, there is the risk that these funds' policies and procedures will prove ineffective in whole or in part to detect or prevent excessive or short-term trading. These funds may alter their policies at any time without prior notice to shareholders if the advisor believes the change would be in the best interests of long-term shareholders.

Invesco Aim Affiliates currently use the following tools designed to discourage excessive short-term trading in the funds:

- Trade activity monitoring.

- Trading guidelines.

- Redemption fees on trades in certain funds.

- The use of fair value pricing consistent with procedures approved by the Board.

Each of these tools is described in more detail below. Although these tools are designed to discourage excessive short-term trading, you should understand that none of these tools alone nor all of them taken together eliminate the possibility that excessive short-term trading activity in the funds will occur. Moreover, each of these tools involves judgments that are inherently subjective. Invesco Aim Affiliates seek to make these judgments to the best of their abilities in a manner that they believe is consistent with long-term shareholder interests.

AIM Limited Maturity Treasury Fund. The Board of AIM Limited Maturity Treasury Fund has not adopted any policies and procedures that would limit frequent purchases and redemptions of such fund's shares. The Board considered the risks of not having a specific policy that limits frequent purchases and redemptions and determined that those risks were minimal. Nonetheless, to the extent that AIM Limited Maturity Treasury Fund must maintain additional cash and/or securities with short-term durations in greater amounts than may otherwise be required or borrow to honor redemption requests, AIM Limited Maturity Treasury Fund's yield could be negatively impacted.

The Board does not believe that it is appropriate to adopt any such policies and procedures for the fund for the following reasons:

- Many investors use AIM Limited Maturity Treasury Fund as a short-term investment alternative and should be able to purchase and redeem shares regularly and frequently.

- One of the advantages of AIM Limited Maturity Treasury Fund as compared to other investment options is liquidity. Any policy that diminishes the liquidity of AIM Limited Maturity Treasury Fund will be detrimental to the continuing operations of such fund.

TRADE ACTIVITY MONITORING

Invesco Aim Affiliates monitor selected trades on a daily basis in an effort to detect excessive short-term trading activities. If, as a result of this monitoring, Invesco Aim Affiliates believe that a shareholder has engaged in excessive short-term trading, they will seek to act in a manner that they believe is consistent with the best interests of long-term investors, which may include taking steps such as (i) asking the shareholder to take action to stop such activities or (ii) refusing to process future purchases or exchanges related to such activities in the shareholder's accounts. Invesco Aim

THE AIM FUNDS - INSTITUTIONAL CLASS

Affiliates will use reasonable efforts to apply the fund's policies uniformly given the practical limitations described above.

The ability of Invesco Aim Affiliates to monitor trades that are made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent.

TRADING GUIDELINES

If you exceed four exchanges out of a fund per calendar year, or a fund or an Invesco Aim Affiliate determines, in its sole discretion, that your short-term trading activity is excessive (regardless of whether or not you exceed such guidelines), it may, in its discretion, reject any additional purchase and exchange orders.

The ability of Invesco Aim Affiliates to monitor exchanges made through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent. If shares of the funds are held in the name of a conduit investment vehicle and not in the names of the individual investors who have invested in the funds through the conduit investment vehicle, the conduit investment vehicle may be considered an individual shareholder of the funds. To the extent that a conduit investment vehicle is considered an individual shareholder of the funds, the funds are likely to be limited in their ability to impose exchange limitations on individual transactions initiated by investors who have invested in the funds through the conduit investment vehicle.

You may be charged a 2% redemption fee if you redeem, including redeeming by exchange, shares of certain funds within 31 days of purchase. For more information on this redemption fee, see "Redeeming Shares--Redemption Fees" section of this prospectus.

The ability of a fund to assess a redemption fee on redemptions effectuated through accounts that are maintained by intermediaries (rather than the funds' transfer agent) and through conduit investment vehicles may be severely limited or non-existent.

FAIR VALUE PRICING

Securities owned by a fund are to be valued at current market value if market quotations are readily available. All other securities and assets of a fund for which market quotations are not readily available are to be valued at fair value determined in good faith using procedures approved by the Board. Fair value pricing may reduce the ability of frequent traders to take advantage of arbitrage opportunities resulting from potentially "stale" prices of portfolio holdings. However, it cannot eliminate the possibility of frequent trading.

PRICING OF SHARES

DETERMINATION OF NET ASSET VALUE

The price of each fund's shares is the fund's net asset value per share. The funds value portfolio securities for which market quotations are readily available at market value. The funds value all other securities and assets for which market quotations are unavailable or unreliable at their fair value in good faith using procedures approved by the Board.. The Board has delegated the daily determination of good faith fair value methodologies to Invesco Aim's Valuation Committee, which acts in accordance with Board approved policies. On a quarterly basis, Invesco Aim provides the Board various reports indicating the quality and effectiveness of its fair value decisions on portfolio holdings. Securities and other assets quoted in foreign currencies are valued in U.S. dollars based on the prevailing exchange rates on that day.

Even when market quotations are available, they may be stale or unreliable because the security is not traded frequently, trading on the security ceased before the close of the trading market or issuer specific events occurred after the security ceased trading or because of the passage of time between the close of the market on which the security trades and the close of the NYSE and when the fund calculates its net asset value. Issuer specific events may cause the last market quotation to be unreliable. Such events may include a merger or insolvency, events which affect a geographical area or an industry segment, such as political events or natural disasters, or market events, such as a significant movement in the U.S. market. Where market quotations are not readily available, including where Invesco Aim determines that the closing price of the security is unreliable, Invesco Aim will value the security at fair value in good faith using procedures approved by the Board. Fair value pricing may reduce the ability of frequent traders to take advantage of arbitrage opportunities resulting from potentially "stale" prices of portfolio holdings. However, it cannot eliminate the possibility of frequent trading.

Fair value is that amount that the owner might reasonably expect to receive for the security upon its current sale. Fair value requires consideration of all appropriate factors, including indications of fair value available from pricing services. A fair value price is an estimated price and may vary from the prices used by other mutual funds to calculate their net asset values.

Invesco Aim may use indications of fair value from pricing services approved by the Board. In other circumstances, the Invesco Aim Valuation Committee may fair value securities in good faith using procedures approved by the Board. As a means of evaluating its fair value process, Invesco Aim routinely compares closing market prices, the next day's opening prices for the security in its primary market if available, and indications of fair value from other sources. Fair value pricing methods and pricing services can change from time to time as approved by the Board.

Specific types of securities are valued as follows:

Senior Secured Floating Rate Loans and Senior Secured Floating Rate Debt Securities. Senior secured floating rate loans and senior secured floating rate debt securities are fair valued using evaluated quotes provided by an independent pricing service. Evaluated quotes provided by the pricing service may reflect appropriate factors such as market quotes, ratings, tranche type, industry, company performance, spread, individual trading characteristics, institution-size trading in similar groups of securities and other market data.

Domestic Exchange Traded Equity Securities. Market quotations are generally available and reliable for domestic exchange traded equity securities. If

A-5

THE AIM FUNDS - INSTITUTIONAL CLASS

market quotations are not available or are unreliable, Invesco Aim will value the security at fair value in good faith using procedures approved by the Board.

Foreign Securities. If market quotations are available and reliable for foreign exchange traded equity securities, the securities will be valued at the market quotations. Because trading hours for certain foreign securities end before the close of the NYSE, closing market quotations may become unreliable. If between the time trading ends on a particular security and the close of the customary trading session on the NYSE events occur that are significant and may make the closing price unreliable, the fund may fair value the security. If an issuer specific event has occurred that Invesco Aim determines, in its judgment, is likely to have affected the closing price of a foreign security, it will price the security at fair value. Invesco Aim also relies on a screening process from a pricing vendor to indicate the degree of certainty, based on historical data, that the closing price in the principal market where a foreign security trades is not the current market value as of the close of the NYSE. For foreign securities where Invesco Aim believes, at the approved degree of certainty, that the price is not reflective of current market value, Invesco Aim will use the indication of fair value from the pricing service to determine the fair value of the security. The pricing vendor, pricing methodology or degree of certainty may change from time to time.

Fund securities primarily traded on foreign markets may trade on days that are not business days of the fund. Because the net asset value of fund shares is determined only on business days of the fund, the value of the portfolio securities of a fund that invests in foreign securities may change on days when you will not be able to purchase or redeem shares of the fund.

Fixed Income Securities. Government, corporate, asset-backed and municipal bonds, convertible securities, including high yield or junk bonds, and loans, normally are valued on the basis of prices provided by independent pricing services. Prices provided by the pricing services may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend rate, maturity and other market data. Prices received from pricing services are fair value prices. In addition, if the price provided by the pricing service and independent quoted prices are unreliable, the Invesco Aim valuation committee will fair value the security using procedures approved by the Board.

Short-term Securities. The funds' short-term investments are valued at amortized cost when the security has 60 days or less to maturity. AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund value variable rate securities that have an unconditional demand or put feature exercisable within seven days or less at par, which reflects the market value of such securities.

Futures and Options. Futures contracts are valued at the final settlement price set by the exchange on which they are principally traded. Options are valued on the basis of market quotations, if available.

Swap Agreements. Swap Agreements are fair valued using an evaluated quote provided by an independent pricing service. Evaluated quotes provided by the pricing service are based on a model that may include end of day net present values, spreads, ratings, industry and company performance.

Open-end Funds. To the extent a fund invests in other open-end funds, other than open-end funds that are exchange traded, the investing fund will calculate its net asset value using the net asset value of the underlying fund in which it invests.

Each fund determines the net asset value of its shares on each day the NYSE is open for business (a business day), as of the close of the customary trading session, or earlier NYSE closing time that day.

For financial reporting purposes and shareholder transactions on the last day of the fiscal quarter, transactions are normally accounted for on a trade date basis. For purposes of executing shareholder transactions in the normal course of business (other than shareholder transactions at a fiscal period-end), each fund's portfolio securities transactions are recorded no later than the first business day following the trade date.

TIMING OF ORDERS

You can purchase, exchange or redeem shares on each business day prior to the close of the customary trading session or any earlier NYSE closing time that day. The funds price purchase, exchange and redemption orders at the net asset value calculated after the transfer agent receives an order in good order. Any applicable sales charges are applied at the time an order is processed. A fund may postpone the right of redemption only under unusual circumstances, as allowed by the SEC, such as when the NYSE restricts or suspends trading.

TAXES

In general, if you are a taxable investor, dividends and distributions you receive are taxable as ordinary income or long-term capital gains for federal income tax purposes. This is true whether you reinvest distributions in additional fund shares or take them in cash. Every year, you will be sent information showing the amount of dividends and distributions you received from each fund during the prior year. Investors in tax-exempt funds should read the information under the heading "Other Information--Special Tax Information Regarding the Fund" in the applicable fund's prospectus. In addition, investors in taxable accounts should be aware of the following basic tax points:

- Distributions of net short-term capital gains are taxable to you as ordinary income. A fund that is expected to have higher turnover than that of other funds is more likely to generate short-term gain or loss.

- Distributions of net long-term capital gains are taxable to you as long-term capital gains no matter how long you have owned your fund shares.

- If you are an individual and meet certain holding period requirements, a portion of income dividends paid by a fund may be designated as qualified dividend income eligible for taxation at long-term capital gain rates. These reduced rates generally are available for dividends paid by a fund out of dividends earned on the fund's investment in stocks of domestic corporations and qualified foreign corporations.

- Distributions declared to shareholders with a record date in December--if paid to you by the end of January--are taxable for federal income tax purposes as if received in December.

A-6

THE AIM FUNDS - INSTITUTIONAL CLASS

- Any long-term or short-term capital gains realized from redemptions of fund shares will be subject to federal income tax. For tax purposes, an exchange of your shares for shares of another fund is the same as a sale.

- If you invest in a fund shortly before it makes a capital gains distribution, the distribution will lower the value of the fund's shares by the amount of the distribution and, in effect, you will receive some of your investment back in the form of a taxable distribution. This is sometimes referred to as "buying a dividend."

- By law, if you do not provide a fund with your proper taxpayer identification number and certain required certifications, you may be subject to backup withholding on any distributions of income, capital gains, or proceeds from the sale of your shares. A fund also must withhold if the IRS instructs it to do so. When withholding is required, the amount will be 28% of any distributions or proceeds paid.

- Fund distributions and gains from sale or exchange of your fund shares generally are subject to state and local income taxes.

- Foreign investors should be aware that U.S. withholding, special certification requirements to avoid U.S. backup withholding and claim any treaty benefits and estate taxes may apply to an investment in a fund.

The preceding discussion concerning the taxability of fund dividends and distributions and of redemptions and exchanges of fund shares is inapplicable to investors that are generally exempt from federal income tax, such as retirement plans that are qualified under Section 401, 403, 408, 408A and 457 of the Code, individual retirement accounts (IRAs) and Roth IRAs. You should consult your tax advisor before investing in a fund.

GENERAL INFORMATION ABOUT THE TRUST

FUND HISTORY

AIM Tax-Exempt Funds (the "Trust") is a Delaware statutory trust which is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company. The Trust currently consists of three separate portfolios: AIM High Income Municipal Fund, AIM Tax-Exempt Cash Fund and AIM Tax-Free Intermediate Fund (each a "Fund" and collectively, the "Funds"). Under the Amended and Restated Agreement and Declaration of Trust, dated September 14, 2005, as amended (the "Trust Agreement"), the Board of Trustees of the Trust (the "Board") is authorized to create new series of shares without the necessity of a vote of shareholders of the Trust.

The Trust was originally incorporated on May 3, 1993 as AIM Tax-Exempt Funds, Inc. ("ATEF"), a Maryland corporation. The Trust reorganized as a Delaware business trust on June 1, 2000. Each Fund acquired all the assets and assumed all of the liabilities of the series portfolios with corresponding names of AIM Tax-Exempt Funds, Inc. All historical financial and other information contained in this Statement of Additional Information for periods prior to June 1, 2000 relating to these Funds (or a class thereof) is that of the predecessor funds (or the corresponding class thereof).

On October 15, 1993, pursuant to an Agreement and Plan of Reorganization between ATEF and AIM Funds Group ("AFG"), a Massachusetts business trust, AIM Tax-Exempt Cash Fund succeeded to the assets and assumed the liabilities of AFG's AIM Tax-Exempt Cash Fund (the "AFG Fund"). Similarly, on October 15, 1993, pursuant to an Agreement and Plan of Reorganization between ATEF and Tax-Free Investments Co., a Maryland corporation ("TFIC"), ATEF's AIM Tax-Free Intermediate Fund (named the Intermediate Portfolio prior to September 25, 1997) succeeded to the assets and assumed the liabilities of TFIC's Intermediate Portfolio (together with the AFG Fund, the "TFIC Predecessor Funds"). All historical financial and other information contained in this Statement of Additional Information for periods prior to October 15, 1993, relating to such Funds is that of the TFIC Predecessor Funds.

SHARES OF BENEFICIAL INTEREST

Shares of beneficial interest of the Trust are redeemable at their net asset value (subject, in certain circumstances, to a contingent deferred sales charge or redemption fee) at the option of the shareholder or at the option of the Trust in certain circumstances.

The Trust allocates moneys and other property it receives from the issue or sale of shares of each of its series of shares, and all income, earnings and profits from such issuance and sales, subject only to the rights of creditors, to the appropriate Fund. These assets constitute the underlying assets of each Fund, are segregated on the Trust's books of account, and are charged with the expenses of such Fund and its respective classes. The Trust allocates any general expenses of the Trust not readily identifiable as belonging to a particular Fund by or under the direction of the Board of Trustees, primarily on the basis of relative net assets, or other relevant factors.

Each share of each Fund represents an equal proportionate interest in that Fund with each other share and is entitled to such dividends and distributions out of the income belonging to such Fund as are declared by the Board.

1

Each Fund offers the following separate classes of shares:

        FUND           CLASS A   CLASS A3   CLASS B   CLASS C   INVESTOR CLASS   INSTITUTIONAL CLASS
--------------------   -------   --------   -------   -------   --------------   -------------------

   Municipal Fund         X                    X         X                                X
AIM Tax-Exempt
   Cash Fund              X                                            X

This Statement of Additional Information relates solely to the Class A, Class A3, Class B, Class C, Investor Class and Institutional Class shares, if applicable, of the Funds. The Institutional Class shares are intended for use by certain eligible institutional investors, including the following:

- banks and trust companies acting in a fiduciary or similar capacity;

- bank and trust company common and collective trust funds;

- banks and trust companies investing for their own account;

- entities acting for the account of a public entity (e.g. Taft-Hartley funds, cities or government agencies);

- defined benefit plans and defined contribution plans offered pursuant to Section 401, 457, 403(a) or 403(b) or (c) (defined contribution plans offered pursuant to Section 403(b) must be sponsored by a Section 501(c)(3) organization);

- platform sponsors with which Invesco Aim Distributors, Inc.("Invesco Aim Distributors") has entered into an agreement;

- proprietary asset allocation funds; and

- Invesco Aim Management Group, Inc. ("Invesco Aim Management") and its affiliates.

Each class of shares represents an interest in the same portfolio of investments. Differing sales charges and expenses will result in differing net asset values and dividends and distributions. Upon any liquidation of the Trust, shareholders of each class are entitled to share pro rata in the net assets belonging to the applicable Fund allocable to such class available for distribution after satisfaction of outstanding liabilities of the Fund allocable to such class.

Each share of a Fund generally has the same voting, dividend, liquidation and other rights; however, each class of shares of a Fund is subject to different sales loads, conversion features, exchange privileges and class specific expenses. Only shareholders of a specific class may vote on matters relating to that class' distribution plan.

Because Class B shares automatically convert to Class A shares on or about month-end which at least eight years after the date of purchase, the Funds' Agreement and Declaration of Trust requires that Class B shareholders must also approve any material increase in distribution fees submitted to Class A shareholders of that Fund. A pro rata portion of shares from reinvested dividends and distributions convert along with the Class B shares.

Except as specifically noted above, shareholders of each Fund are entitled to one vote per share (with proportionate voting for fractional shares), irrespective of the relative net asset value of the shares of a Fund. However, on matters affecting an individual Fund or class of shares, a separate vote of shareholders of that Fund or class is required. Shareholders of a Fund or class are not entitled to vote on any matter which does not affect that Fund or class but that requires a separate vote of another Fund or class. An example of a matter that would be voted on separately by shareholders of each Fund is the approval of the advisory agreement with Invesco Aim Advisors, Inc. ("Invesco Aim"), and an example of a matter that would be voted on separately by shareholders of each class of shares is approval of the distribution plans. When issued, shares of each Fund are fully paid and nonassessable, have no

2

preemptive or subscription rights, and are freely transferable. Other than the automatic conversion of Class B shares to Class A shares, there are no conversion rights. Shares do not have cumulative voting rights, which means that in situations in which shareholders elect trustees, holders of more than 50% of the shares voting for the election of trustees can elect all of the trustees of the Trust, and the holders of less than 50% of the shares voting for the election of trustees will not be able to elect any trustees.

Under Delaware law, shareholders of a Delaware statutory trust shall be entitled to the same limitations of liability extended to shareholders of private for-profit corporations. There is a remote possibility, however, that shareholders could, under certain circumstances, be held liable for the obligations of the Trust to the extent the courts of another state which does not recognize such limited liability were to apply the laws of such state to a controversy involving such obligations. The Trust Agreement disclaims shareholder liability for acts or obligations of the Trust and requires that notice of such disclaimer be given in each agreement, obligation or instrument entered into or executed by the Trust or the trustees to all parties, and each party thereto must expressly waive all rights of action directly against shareholders of the Trust. The Trust Agreement provides for indemnification out of the property of a Fund for all losses and expenses of any shareholder of such Fund held liable on account of being or having been a shareholder. Thus, the risk of a shareholder incurring financial loss due to shareholder liability is limited to circumstances in which a Fund is unable to meet its obligations and the complaining party is not held to be bound by the disclaimer.

The trustees and officers of the Trust will not be liable for any act, omission or obligation of the Trust or any Trustee or officer; however, a trustee or officer is not protected against any liability to the Trust or to the shareholders to which a trustee or officer would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his or her office with the Trust ("Disabling Conduct"). The Trust's By-laws generally provide for indemnification by the Trust of the trustees, the officers and employees or agents of the Trust, provided that such persons have not engaged in Disabling Conduct. Indemnification does not extend to judgments or amounts paid in settlement in any actions by or in the right of the Trust. The Trust's Bylaws provide for the advancement of payments of expenses to current and former trustees, officers and employees or agents of the Trust, or anyone serving at their request, in connection with the preparation and presentation of a defense to any claim, action, suit or proceeding for which such person would be entitled to indemnification; provided that any advancement of payments would be reimbursed unless it is ultimately determined that such person is entitled to indemnification for such expenses.

SHARE CERTIFICATES. Shareholders of the Funds do not have the right to demand or require the Trust to issue share certificates and share certificates are not issued.

DESCRIPTION OF THE FUNDS AND THEIR INVESTMENTS AND RISKS

CLASSIFICATION

The Trust is an open-end management investment company. Each of the Funds is "diversified" for purposes of the 1940 Act.

INVESTMENT STRATEGIES AND RISKS

Set forth below are detailed descriptions of the various types of securities and investment techniques that Invesco Aim and/or the Sub-Advisors (as defined herein) may use in managing the Funds, as well as the risks associated with those types of securities and investment techniques. The descriptions of the types of securities and investment techniques below supplement the discussion of principal investment strategies and risks contained in each Fund's Prospectus; where a particular type of security or investment technique is not discussed in a Fund's Prospectus, that security or investment technique is not a principal investment strategy.

3

Not all of the Funds invest in all of the types of securities or use all of the investment techniques described below, and a fund may not invest in all of these types of securities or use all of these techniques at any one time. A Fund's transactions in a particular type of security or use of a particular technique is subject to limitations imposed by a Fund's investment objective, policies and restrictions described in that Fund's Prospectus and/or this Statement of Additional Information, as well as the federal securities laws. Invesco Aim and/or the Sub-Advisors may invest in other types of securities and may use other investment techniques in managing the Funds, subject to limitations imposed by a Fund's investment objective, policies and restrictions described in that Fund's Prospectus and/or this Statement of Additional Information, as well as the federal securities laws.

The Funds' investment objectives, policies, strategies and practices described below are non-fundamental unless otherwise indicated.

Exchange Traded Funds

EXCHANGE TRADED FUNDS. Each Fund may purchase shares of exchange-traded funds ("ETFs"). Most ETFs are registered under the 1940 Act as investment companies. Therefore, a Fund's purchase of shares of an ETF may be subject to the restrictions on investments in other investment companies discussed under "Other Investment Companies."

ETFs hold portfolios of securities, commodities and/or currencies that are designed to replicate, as closely as possible before expenses, the price and/or yield of (i) a specified market or other index, (ii) a basket of securities, commodities or currencies, or (iii) a particular commodity or currency. The performance results of ETFs will not replicate exactly the performance of the pertinent index, basket, commodity or currency due to transaction and other expenses, including fees to service providers, borne by ETFs. ETF shares are sold and redeemed at net asset value only in large blocks called creation units and redemption units, respectively. ETF shares also may be purchased and sold in secondary market trading on national securities exchanges, which allows investors to purchase and sell ETF shares at their market price throughout the day.

Investments in ETFs generally present the same primary risks as an investment in a conventional mutual fund that has the same investment objective, strategy and policies. Investments in ETFs further involve the same risks associated with a direct investment in the commodity or currency, or in the types of securities, commodities and/or currencies included in the indices or baskets the ETFs are designed to replicate. In addition, shares of an ETF may trade at a market price that is higher or lower than their net asset value and an active trading market in such shares may not develop or continue. Moreover, trading of an ETF's shares may be halted if the listing exchange's officials deem such action to be appropriate, the shares are de-listed from the exchange, or the activation of market-wide "circuit breakers" (which are tied to large decreases in stock prices) halts stock trading generally. Finally, there can be no assurance that the portfolio of securities, commodities and/or currencies purchased by an ETF will replicate a particular index or basket or price of a commodity or currency.

Debt Investments

U.S. GOVERNMENT OBLIGATIONS. Each Fund may invest in U.S. Government obligations. Obligations issued or guaranteed by the U.S. Government, its agencies and instrumentalities including bills, notes and bonds issued by the U.S. Treasury, as well as "stripped" or "zero coupon" U.S. Treasury obligations representing future interest or principal payments on U.S. Treasury notes or bonds. Stripped securities are sold at a discount to their "face value," and may exhibit greater price volatility than interest-bearing securities since investors receive no payment until maturity. Obligations of certain agencies and instrumentalities of the U.S. Government, such as the Government National Mortgage Association ("GNMA"), are supported by the full faith and credit of the U.S. Treasury; others, such as those of the Federal National Mortgage Association ("FNMA"), are supported by the right of the issuer to borrow from the U.S. Treasury; others, such as those of the Student Loan Marketing Association ("SLMA"), are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others, though issued by an instrumentality chartered by the U.S. Government, like the Federal Farm

4

Credit Bureau ("FFCB"), are supported only by the credit of the instrumentality. The U.S. Government may choose not to provide financial support to U.S. Government-sponsored agencies or instrumentalities if it is not legally obligated to do so, in which such case if the issuer were to default, the Fund holding securities of such issuer might not be able to recover their investments.

RULE 2A-7 REQUIREMENTS. Money market instruments in which the AIM Tax-Exempt Cash Fund will invest will be "Eligible Securities" as defined in Rule 2a-7 under the 1940 Act, as such Rule may be amended from time to time. An Eligible Security is generally a rated security with a remaining maturity of 397 calendar days or less that has been rated by the Requisite NRSROs (as defined below) in one of the two highest short-term rating categories, or a security issued by an issuer that has received a rating by the Requisite NRSROs in one of the two highest short-term rating categories with respect to a class of debt obligations (or any debt obligation within that class). Eligible Securities may also include unrated securities determined by Invesco Aim (under the supervision of and pursuant to guidelines established by the Board) to be of comparable quality to such rated securities. Eligible securities also include securities issued by a registered investment company that is a money market fund and U.S. government securities. If an unrated security is subject to a guarantee, to be an Eligible Security, the guarantee generally must have received a rating from an NRSRO in one of the two highest short-term rating categories or be issued by a guarantor that has received a rating from an NRSRO in one of the two highest short-term rating categories with respect to a class of debt obligations (or any debt obligation within that class). The term "Requisite NRSRO" means (a) any two nationally recognized statistical rating organizations (NRSROs) that have issued a rating with respect to a security or class of debt obligations of an issuer, or (b) if only one NRSRO has issued a rating with respect to such security or issuer at the time the Fund acquires the security, that NRSRO.

Should AIM Tax-Exempt Cash Fund invest in "Second Tier Securities" as defined in Rule 2a-7 under the 1940 Act, as such Rule may be amended from time to time, it will limit its investments in Second Tier Securities such that, immediately after the acquisition of any Second Tier Security, (i) no more than 5% of the Fund's total assets will be invested in Second Tier Securities and
(ii) no more than the greater of 1% of the Fund's total assets or $1 million will be invested in securities issued by that issuer that are Second Tier Securities.

AIM Tax-Exempt Cash Fund will attempt to maintain a constant net asset value per share of $1.00 and, to this end, values its assets by the amortized cost method and rounds the per share net asset value of its shares in compliance with applicable rules and regulations. Accordingly, the Fund invests only in securities having remaining maturities of 397 days or less and maintains a dollar weighted average portfolio maturity of 90 days or less. The maturity of a security held by the Fund is determined in compliance with applicable rules and regulations. Certain securities bearing interest at rates that are adjusted prior to the stated maturity of the instrument or that are subject to redemption or repurchase agreements are deemed to have maturities shorter than their stated maturities.

MORTGAGE-BACKED AND ASSET-BACKED SECURITIES. AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund may invest in mortgage-backed and asset-backed securities. Mortgage-backed securities are mortgage-related securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities, or issued by nongovernment entities. Mortgage-related securities represent pools of mortgage loans assembled for sale to investors by various government agencies such as GNMA and government-related organizations such as FNMA and the Federal Home Loan Mortgage Corporation ("FHLMC"), as well as by nongovernment issuers such as commercial banks, savings and loan institutions, mortgage bankers and private mortgage insurance companies. Although certain mortgage-related securities are guaranteed by a third party or otherwise similarly secured, the market value of the security, which may fluctuate, is not so secured.

There are a number of important differences among the agencies and instrumentalities of the U.S. Government that issue mortgage-related securities and among the securities they issue. Mortgage-related securities issued by GNMA include GNMA Mortgage Pass-Through Certificates (also known as "Ginnie Maes") which are guaranteed as to the timely payment of principal and interest. That guarantee is backed by the full faith and credit of the U.S. Treasury. GNMA is a corporation wholly owned by the

5

U.S. Government within the Department of Housing and Urban Development. Mortgage-related securities issued by FNMA include FNMA Guaranteed Mortgage Pass-Through Certificates (also known as "Fannie Maes") and are guaranteed as to payment of principal and interest by FNMA itself and backed by a line of credit with the U.S. Treasury. FNMA is a government-sponsored entity wholly owned by public stockholders. Mortgage-related securities issued by FHLMC include FHLMC Mortgage Participation Certificates (also known as "Freddie Macs") guaranteed as to payment of principal and interest by FHLMC itself and backed by a line of credit with the U.S. Treasury. FHLMC is a government-sponsored entity wholly owned by public stockholders.

Other asset-backed securities are structured like mortgage-backed securities, but instead of mortgage loans or interests in mortgage loans, the underlying assets may include such items as motor vehicle installment sales or installment loan contracts, leases of various types of real and personal property, and receivables from credit card agreements. Regular payments received in respect of such securities include both interest and principal. Asset-backed securities typically have no U.S. Government backing. Additionally, the ability of an issuer of asset-backed securities to enforce its security interest in the underlying assets may be limited.

If a Fund purchases a mortgage-backed or other asset-backed security at a premium, that portion may be lost if there is a decline in the market value of the security whether resulting from changes in interest rates or prepayments in the underlying collateral. As with other interest-bearing securities, the prices of such securities are inversely affected by changes in interest rates. Although the value of a mortgage-backed or other asset-backed security may decline when interest rates rise, the converse is not necessarily true, since in periods of declining interest rates the mortgages and loans underlying the securities are prone to prepayment, thereby shortening the average life of the security and shortening the period of time over which income at the higher rate is received. When interest rates are rising, the rate of prepayment tends to decrease, thereby lengthening the period of time over which income at the lower rate is received. For these and other reasons, a mortgage-backed or other asset-backed security's average maturity may be shortened or lengthened as a result of interest rate fluctuations and, therefore, it is not possible to predict accurately the security's return.

BANK INSTRUMENTS. The Funds may invest in certificates of deposits, time deposits, and bankers' acceptances from U.S. banks. A certificate of deposit is a negotiable interest-bearing instrument with a specific maturity. Certificates of deposit are issued by banks and savings and loan institutions in exchange for the deposit of funds, and normally can be traded in the secondary market prior to maturity. A time deposit is a non-negotiable receipt issued by a bank in exchange for the deposit of funds. Like a certificate of deposit, it earns a specified rate of interest over a definite period of time; however, it cannot be traded in the secondary market. A banker's acceptance is a bill of exchange or time draft drawn on and accepted by a commercial bank.

COMMERCIAL INSTRUMENTS. Each Fund may invest in commercial instruments, including commercial paper, master notes and other short-term corporate instruments, that are denominated in U.S. dollars. Commercial paper consists of short-term promissory notes issued by corporations. Commercial paper may be traded in the secondary market after its issuance. Master notes are demand notes that permit the investment of fluctuating amounts of money at varying rates of interest pursuant to arrangements with issuers who meet the quality criteria of the Fund. The interest rate on a master note may fluctuate based upon changes in specified interest rates or be reset periodically according to a prescribed formula or may be a set rate. Although there is no secondary market in master demand notes, if such notes have a demand feature, the payee may demand payment of the principal amount of the note upon relatively short notice. Master notes are generally illiquid and therefore subject to the Funds' percentage limitation for investments in illiquid securities.

MUNICIPAL SECURITIES. Each Fund may invest in municipal securities. "Municipal Securities" include debt obligations of states, territories and possessions of the United States and the District of Columbia and their political subdivisions, agencies and instrumentalities, authorities thereof, and multi-state agencies, issued to obtain funds for various public purposes, including the construction of a wide

6

range of public facilities such as airports, bridges, highways, housing, hospitals, mass transportation, schools, streets and water and sewer works.

Other public purposes for which Municipal Securities may be issued include the refunding of outstanding obligations, obtaining funds for general operating expenses and lending such funds to other public institutions and facilities. In addition, certain types of industrial development bonds are issued by or on behalf of public authorities to obtain funds to provide for the construction, equipment, repair or improvement of privately operated housing facilities, airport, mass transit, industrial, port or parking facilities, air or water pollution control facilities and certain local facilities for water supply, gas, electricity or sewage or solid waste disposal. The principal and interest payments for industrial development bonds or pollution control bonds are often the sole responsibility of the industrial user and therefore may not be backed by the taxing power of the issuing municipality. The interest paid on such bonds may be exempt from federal income tax, although current federal tax laws place substantial limitations on the purposes and size of such issues. Such obligations are considered to be Municipal Securities provided that the interest paid thereon, in the opinion of bond counsel, qualifies as exempt from federal income tax. However, interest on Municipal Securities may give rise to a federal alternative minimum tax ("AMT") liability and may have other collateral federal income tax consequences. See "Dividends, Distributions and Tax Matters - Tax Matters."

The two major classifications of Municipal Securities are bonds and notes. Bonds may be further classified as "general obligation" or "revenue" issues. General obligation bonds are secured by the issuer's pledge of its full faith, credit and taxing power for the payment of principal and interest. Revenue bonds are payable from the revenues derived from a particular facility or class of facilities, and in some cases, from the proceeds of a special excise or other specific revenue source, but not from the general taxing power. Tax-exempt industrial development bonds are in most cases revenue bonds and do not generally carry the pledge of the credit of the issuing municipality. Notes are short-term instruments which usually mature in less than two years. Most notes are general obligations of the issuing municipalities or agencies and are sold in anticipation of a bond sale, collection of taxes or receipt of other revenues. There are, of course, variations in the risks associated with Municipal Securities, both within a particular classification and between classifications. The Funds' assets may consist of any combination of general obligation bonds, revenue bonds, industrial revenue bonds and notes.

Municipal Securities also include the following securities:

- Bond Anticipation Notes usually are general obligations of state and local governmental issuers which are sold to obtain interim financing for projects that will eventually be funded through the sale of long-term debt obligations or bonds.

- Tax Anticipation Notes are issued by state and local governments to finance the current operations of such governments. Repayment is generally to be derived from specific future tax revenues. Tax anticipation notes are usually general obligations of the issuer.

- Revenue Anticipation Notes are issued by governments or governmental bodies with the expectation that future revenues from a designated source will be used to repay the notes. In general, they also constitute general obligations of the issuer.

- Tax-Exempt Commercial Paper (Municipal Paper) is similar to taxable commercial paper, except that tax-exempt commercial paper is issued by states, municipalities and their agencies.

AIM Tax-Free Intermediate Fund and AIM Tax-Exempt Cash Fund limit their investment in certain types of Municipal Securities as follows: (i) less than 25% of its total assets will be invested in securities of issuers who are located in the same state; (ii) less than 25% of its total assets will be invested in industrial development bonds; and (iii) less than 25% of its total assets will be invested in securities the interest on which is paid from revenues of similar type projects (similar project securities). However, industrial development bonds and similar project securities will not be counted towards the applicable

7

25% limit if they are subject to a guarantee, including a letter of credit, financial guaranty insurance, or are refunded securities (meaning that payments of principal and interest on such securities are paid by U.S. government securities that have been irrevocably placed in an escrow account and are pledged only to such payments).

AIM High Income Municipal Fund also may purchase participation interests or custodial receipts from financial institutions. These participation interests give the purchaser an undivided interest in one or more underlying Municipal Securities.

Subsequent to its purchase by a Fund, an issue of Municipal Securities may cease to be rated by Moody's Investors Service, Inc. ("Moody's") or Standard and Poor's Ratings Services ("S&P"), or another NRSRO, or the rating of such a security may be reduced below the minimum rating required for purchase by a Fund. Neither event would require a Fund to dispose of the security, but Invesco Aim will consider such events to be relevant in determining whether the Fund should continue to hold the security.

There is a risk that some or all of the interest received by a Fund from Municipal Securities might become taxable as a result of tax law changes or determinations of the Internal Revenue Service ("IRS").

The yields on Municipal Securities are dependent on a variety of factors, including general economic and monetary conditions, money market factors, conditions of the Municipal Securities market, size of a particular offering, and maturity and rating of the obligation. The market values of the Municipal Securities held by a Fund will be affected by changes in the yields available on similar securities. If yields increase following the purchase of a Municipal Security, the market value of such Municipal Security will generally decrease. Conversely, if yields decrease, the market value of a Municipal Security will generally increase.

Maturities. AIM Tax-Free Intermediate Fund will maintain a dollar weighted average maturity of at least three years and not more than ten years. For purposes of this limitation, the maturity of an instrument will be considered to be the earlier of:

(a) the stated maturity of the instrument; or

(b) the date, if any, on which the issuer has agreed to redeem or purchase the instrument; or

(c) in the case of a variable rate instrument, the next date on which the coupon rate is to be adjusted.

AIM High Income Municipal Fund may invest its assets without regard to the maturity of the various securities it purchases, and will not seek to maintain any particular average portfolio maturity.

Quality Standards. The following quality standards apply at the time a security is purchased. Information concerning the ratings criteria of Moody's, S&P, and Fitch Investors Service, Inc. ("Fitch") appears herein under "Appendix A - Ratings of Debt Securities".

AIM Tax-Free Intermediate Fund. At least 80% of the Fund's assets will normally be invested in Municipal Securities to be of investment grade because they meet one of the following quality criteria:

(a) They are rated within the four highest ratings for municipal obligations by Moody's (Aaa, Aa, A or Baa) or S&P (AAA, AA, A or BBB), or have received a comparable rating from another NRSRO;

(b) (1) They are rated within the three highest ratings for short-term municipal obligations by Moody's (MIG /VMIG 1/P-1, MIG 2/VMIG 2/P-2 or MIG 3/VMIG 3/P-3), (2) they are rated within the two highest ratings for short-term municipal obligations by S&P (SP-1/A-1 or SP-2/A-2), or (3) have received a comparable rating from another NRSRO;

(c) They are guaranteed as to payment of principal and interest by the U. S. Government;

8

(d) They are fully collateralized by an escrow of U.S. Government or other high quality securities; or

(e) Unrated securities, if (1) other Municipal Securities of the same issuer are rated BBB or better by an NRSRO, or (2) they are deemed by the portfolio managers to be of comparable quality.

AIM Tax-Free Intermediate Fund invests in Municipal Securities backed by insurance companies and other financial institutions. Therefore, changes in the financial condition of these institutions could cause losses to the Fund and affect its share price.

Since a limited number of entities provide such insurance, the Fund may invest more than 25% of its assets in securities insured by the same insurance company.

AIM Tax-Exempt Cash Fund. Since AIM Tax-Exempt Cash Fund invests in Municipal Securities backed by banks and other financial institutions, changes in the credit quality of these institutions could cause losses to the Fund and affect its share price.

Insurance. AIM High Income Municipal Fund may purchase insurance for non-insured Municipal Securities in which it invests. The purchase of such insurance is expected to enhance the value of the security for which insurance is purchased. The cost of purchasing such insurance would be an expense of the Fund.

Other Considerations. The ability of each of AIM Tax-Exempt Cash Fund and AIM Tax-Free Intermediate Fund to achieve their respective investment objectives depends upon the continuing ability of the issuers or guarantors of Municipal Securities held by the Funds to meet their obligations for the payment of interest and principal when due. The securities in which such Funds invest may not yield as high a level of current income as longer term or lower grade securities, which generally have less liquidity and greater fluctuation in value.

AIM Tax-Free Intermediate Fund will invest its assets so that 80% of the Fund's assets will be invested in securities that generate interest that is exempt from Federal income taxes. The Fund will seek to avoid the purchase of "private activity bonds" the interest on which could give rise to an AMT liability for individuals and other noncorporate shareholders. At the present time, the Fund will not invest in municipal debt securities if the interest on such securities is subject to the federal alternative minimum tax.

SYNTHETIC MUNICIPAL INSTRUMENTS. The Funds may invest in synthetic municipal instruments the value of and return on which are derived from underlying securities. Invesco Aim believes that certain synthetic municipal instruments provide opportunities for mutual funds to invest in high credit quality securities providing attractive returns, even in market conditions where the supply of short-term tax-exempt instruments may be limited. Synthetic municipal instruments comprise a large percentage of tax-exempt securities eligible for purchase by tax-exempt money market funds. The types of synthetic municipal instruments in which the Fund may invest include tender option bonds and variable rate trust certificates. Both types of instruments involve the deposit into a trust or custodial account of one or more long-term tax-exempt bonds or notes ("Underlying Bonds"), and the sale of certificates evidencing interests in the trust or custodial account to investors such as the Fund. The trustee or custodian receives the long-term fixed rate interest payments on the Underlying Bonds, and pays certificate holders short-term floating or variable interest rates that are reset periodically. A "tender option bond" provides a certificate holder with the conditional right to sell its certificate to the Sponsor or some designated third party at specified intervals and receive the par value of the certificate plus accrued interest (a demand feature). A "variable rate trust certificate" evidences an interest in a trust entitling the certificate holder to receive variable rate interest based on prevailing short-term interest rates and also typically providing the certificate holder with the conditional demand feature the right to tender its certificate at par value plus accrued interest.

9

All synthetic municipal instruments must meet the minimum quality standards for AIM Tax-Exempt Cash Fund's investments and must present minimal credit risks. In selecting synthetic municipal instruments for the Fund, Invesco Aim considers the creditworthiness of the issuer of the Underlying Bond, the Sponsor and the party providing certificate holders with a conditional right to sell their certificates at stated times and prices (a demand feature). Typically, a certificate holder cannot exercise the demand feature upon the occurrence of certain conditions, such as where the issuer of the Underlying Bond defaults on interest payments. Moreover, because synthetic municipal instruments involve a trust or custodial account and a third party conditional demand feature, they involve complexities and potential risks that may not be present where a municipal security is owned directly.

The tax-exempt character of the interest paid to certificate holders is based on the assumption that the holders have an ownership interest in the Underlying Bonds; however, the IRS has not issued a ruling addressing this issue. In the event the IRS issues an adverse ruling or successfully litigates this issue, it is possible that the interest paid to AIM Tax-Exempt Cash Fund on certain synthetic municipal instruments would be deemed to be taxable. AIM Tax-Exempt Cash Fund relies on opinions of special tax counsel provided to the trustees and others on this ownership question and opinions of bond counsel regarding the tax-exempt character of interest paid on the Underlying Bonds.

MUNICIPAL LEASE OBLIGATIONS. AIM High Income Municipal Fund and AIM Tax-Exempt Cash Fund may invest in municipal lease obligations. Municipal lease obligations, a type of Municipal Security, may take the form of a lease, an installment purchase or a conditional sales contract. Municipal lease obligations are issued by state and local governments and authorities to acquire land, equipment and facilities such as state and municipal vehicles, telecommunications and computer equipment, and other capital assets. Interest payments on qualifying municipal leases are exempt from federal income taxes. Each Fund may purchase these obligations directly, or it may purchase participation interests in such obligations. Municipal leases are generally subject to greater risks than general obligation or revenue bonds. State laws set forth requirements that states or municipalities must meet in order to issue municipal obligations, and such obligations may contain a covenant by the issuer to budget for, appropriate, and make payments due under the obligation. However, certain municipal lease obligations may contain "non-appropriation" clauses which provide that the issuer is not obligated to make payments on the obligation in future years unless funds have been appropriated for this purpose each year. Accordingly, such obligations are subject to "non-appropriation" risk. While municipal leases are secured by the underlying capital asset, it may be difficult to dispose of such assets in the event of non-appropriation or other default. All direct investments by a Fund in municipal lease obligations shall be deemed illiquid and shall be valued according to the Fund's Procedures for Valuing Securities current at the time of such valuation.

INVESTMENT GRADE DEBT OBLIGATIONS. Each Fund may invest in U.S. dollar-denominated debt obligations issued or guaranteed by U.S. corporations or U.S. commercial banks. Such debt obligations include, among others, bonds, notes, debentures and variable rate demand notes. In choosing corporate debt securities on behalf of a Fund, its investment adviser may consider (i) general economic and financial conditions; (ii) the specific issuer's (a) business and management, (b) cash flow, (c) earnings coverage of interest and dividends, (d) ability to operate under adverse economic conditions, (e) fair market value of assets; and, (iii) other considerations deemed appropriate.

Each Fund may from time to time invest in taxable short-term investments ("Taxable Investments") consisting of obligations of the U.S. Government, its agencies or instrumentalities, banks and corporations, short-term fixed income securities, and repurchase agreements/reverse repurchase agreements (instruments under which the seller agrees to repurchase the security at a specified time and price) relating thereto; commercial paper rated within the highest rating category by a recognized rating agency; and certificates of deposit of domestic banks. A Fund may invest in Taxable Investments, for example, due to market conditions or pending the investment of proceeds from the sale of its shares or proceeds from the sale of portfolio securities or in anticipation of redemptions. Although interest earned from Taxable Investments will be taxable to shareholders as ordinary income, the Funds generally intend to minimize taxable income through investment, when possible, in short-term tax-exempt securities, which

10

may include shares of other investment companies whose dividends are tax-exempt. See also "Dividends, Distributions and Tax Matters."

Descriptions of debt securities ratings are found in Appendix A.

JUNK BONDS. AIM Tax-Free Intermediate Fund may invest up to 20% of its total assets in Municipal Securities which are junk bonds, and the interest of which is exempt from federal income taxes (including the AMT). AIM High Income Municipal Fund will usually maintain, under normal market conditions, at least 80% of its assets in a diversified portfolio of Municipal Securities which are junk bonds, and the interest of which is exempt from federal income taxes (including the AMT).

Junk bonds are considered speculative with respect to their capacity to pay interest and repay principal. While they may provide greater income and opportunity for gain, junk bonds are subject to greater risks than higher-rated debt securities. The prices of and yields on junk bonds may fluctuate to a greater extent than those of higher-rated debt securities.

Issuers of junk bonds are often highly leveraged, and may lack more traditional methods of financing. The risk of issuer default on junk bonds is generally higher because such issues are often unsecured or otherwise subordinated to claims of the issuer's other creditors. If a junk bond issuer defaults, a Fund may incur additional expenses to seek recovery.

Junk bonds have been found to be less sensitive to fluctuations in interest rates, and more sensitive to real or perceived adverse economic conditions and individual corporate developments (including industry competition and adverse publicity), than those of higher-rated debt securities, which can decrease the liquidity and values of junk bonds. During periods of recession and economic downturns, highly leveraged junk bond issuers may experience financial stress and may lack sufficient revenues to meet interest payment obligations, increasing the risk of default. In addition, new laws and proposed new laws may adversely impact the market for junk bonds.

A Fund may have difficulty selling certain junk bonds at the desired time and price. The secondary markets in which junk bonds are traded may be thin and less liquid than the market for higher-rated debt securities. Less liquidity in secondary trading markets could adversely affect the price at which a Fund could sell a particular junk bond, and could adversely affect and cause large fluctuations in the net asset value of that Fund's shares. The lack of a liquid secondary market may also make it more difficult for a Fund to obtain accurate market quotations in valuing junk bond assets.

Other Investments

OTHER INVESTMENT COMPANIES. Each Fund may purchase shares of other investment companies. For each Fund, the 1940 Act imposes the following restrictions on investments in other investment companies: (i) a Fund may not purchase more than 3% of the total outstanding voting stock of another investment company; (ii) a Fund may not invest more than 5% of its total assets in securities issued by another investment company; and (iii) a Fund may not invest more than 10% of its total assets in securities issued by other investment companies. These restrictions do not apply to investments by the Funds in investment companies that are money market funds, including money market funds that have Invesco Aim or an affiliate of Invesco Aim as an investment advisor (the "Affiliated Money Market Funds").

With respect to a Fund's purchase of shares of another investment company, including an Affiliated Money Market Fund, the Fund will indirectly bear its proportionate share of the advisory fees and other operating expenses of such investment company.

DEFAULTED SECURITIES. AIM High Income Municipal Fund may invest up to 10% of its total assets in defaulted securities. In order to enforce its rights in defaulted securities, AIM High Income Municipal Fund may be required to participate in various legal proceedings or take possession of and manage assets securing the issuer's obligations on the defaulted securities. This could increase AIM High Income Municipal Fund's operating expenses and adversely affect its net asset value. Any income derived from

11

the ownership or operation of such assets would not be tax-exempt. The ability of a holder of a defaulted tax-exempt security to enforce the terms of that security in a bankruptcy proceeding may be more limited than would be the case with respect to securities of private issuers. Any investments by AIM High Income Municipal Fund in defaulted securities will also be considered illiquid securities subject to the limitations described herein, unless Invesco Aim determines that such defaulted securities are liquid under guidelines adopted by the Board.

MUNICIPAL FORWARD CONTRACTS. AIM High Income Municipal Fund may invest up to 5% of the value of its total assets in municipal forward contracts. A municipal forward contract is a Municipal Security which is purchased on a when-issued basis with delivery taking place up to five years from the date of purchase. Invesco Aim will monitor the liquidity, value, credit quality and delivery of the security under the supervision of the Board of Trustees.

VARIABLE OR FLOATING RATE INSTRUMENTS. Each Fund may invest in Municipal Securities which have variable or floating interest rates which are readjusted on set dates (such as the last day of the month or calendar quarter) in the case of variable rates or whenever a specified interest rate change occurs in the case of a floating rate instrument. Variable or floating interest rates generally reduce changes in the market price of Municipal Securities from their original purchase price because, upon readjustment, such rates approximate market rates. Accordingly, as interest rates decrease or increase, the potential for capital appreciation or depreciation is less for variable or floating rate Municipal Securities than for fixed rate obligations. Many Municipal Securities with variable or floating interest rates purchased by a Fund are subject to payment of principal and accrued interest (usually within seven days) on the Fund's demand. The terms of such demand instruments require payment of principal and accrued interest by the issuer, a guarantor, and/or a liquidity provider. All variable or floating rate instruments will meet the applicable quality standards of a Fund. Invesco Aim will monitor the pricing, quality and liquidity of the variable or floating rate Municipal Securities held by the Funds.

AIM High Income Municipal Fund may invest in inverse floating rate obligations or residual interest bonds, or other obligations or certificates related to such securities which have similar features. These types of obligations generally have floating or variable interest rates that move in the opposite direction of short-term interest rates, and generally increase or decrease in value in response to changes in short-term interest rates at a rate which is a multiple (typically two) of the rate at which long-term fixed rate tax-exempt securities increase or decrease in response to such changes. As a result, such obligations have the effect of providing investment leverage and may be more volatile than long-term fixed rate tax-exempt securities.

INDEXED SECURITIES. AIM High Income Municipal Fund may invest in indexed securities the value of which is linked to interest rates, commodities, indices or other financial indicators. Most indexed securities are short to intermediate term fixed income securities whose values at maturity (principal value) or interest rates rise or fall according to changes in the value of one or more specified underlying instruments. Indexed securities may be positively or negatively indexed (i.e., their principal value or interest rates may increase or decrease if the underlying instrument appreciates), and may have return characteristics similar to direct investments in the underlying instrument or to one or more options on the underlying instrument. Indexed securities may be more volatile than the underlying instrument itself and could involve the loss of all or a portion of the principal amount of the indexed security.

ZERO-COUPON AND PAY-IN-KIND SECURITIES. AIM High Income Municipal Fund may, but does not currently intend to, invest in zero-coupon or pay-in-kind securities. These securities are debt securities that do not make regular cash interest payments. Zero-coupon securities are sold at a deep discount to their face value. Pay-in-kind securities pay interest through the issuance of additional securities. Because zero-coupon and pay-in-kind securities do not pay current cash income, the price of these securities can be volatile when interest rates fluctuate. While these securities do not pay current cash income, federal tax law requires the holders of zero-coupon and pay-in-kind securities to include in income each year the portion of the original issue discount (or deemed discount) and other non-cash income on such securities accrued during that year. In order to qualify as a "regulated investment company" under the Internal Revenue Code of 1986, as amended (the "Code") and to avoid certain

12

excise taxes, AIM High Income Municipal Fund may be required to distribute a portion of such discount and income, and may be required to dispose of other portfolio securities, which could occur during periods of adverse market prices, in order to generate sufficient cash to meet these distribution requirements.

PARTICIPATION INTERESTS. AIM High Income Municipal Fund may invest in participation interests. Participation interests generally will be acquired from a commercial bank or other financial institution (a "Lender") or from other holders of a participation interest (a "Participant"). The purchase of a participation interest either from a Lender or a Participant will not result in any direct contractual relationship with the borrowing company (the "Borrower"). The Fund generally will have no right directly to enforce compliance by the Borrower with the terms of the credit agreement. Instead, the Fund will be required to rely on the Lender or the Participant that sold the participation interest both for the enforcement of the Fund's rights against the Borrower and for the receipt and processing of payments due to the Fund under the loans. Under the terms of a participation interest, a Fund may be regarded as a creditor of the Participant and thus a Fund is subject to the credit risk of both the Borrower and Lender or a Participant. Participation interests are generally subject to restrictions on resale. The Funds consider participation interests to be illiquid and therefore subject to the Funds' percentage limitation for investments in illiquid securities.

PARTICIPATION NOTES. A Fund may invest in participation notes. Participation notes are generally traded over-the-counter and are subject to counterparty risk. Counterparty risk is the risk that the broker-dealer or bank that issues them will not fulfill its contractual obligation to complete the transaction with the Fund. Participation notes constitute general unsecured contractual obligations of the banks or broker-dealers that issue them, and a Fund is relying on the creditworthiness of such banks or broker-dealers and has no rights under a participation note against the issuer of the underlying assets.

INVESTMENTS IN ENTITIES WITH RELATIONSHIPS WITH THE FUNDS/ADVISOR. Each Fund may invest in securities issued, sponsored or guaranteed by the following types of entities or their affiliates: (i) entities that sell shares of the AIM Funds; (ii) entities that rate or rank the AIM Funds; (iii) exchanges on which the AIM Funds buy or sell securities; and (iv) entities that provide services to the AIM Funds (e.g., custodian banks). The Funds will decide whether to invest in or sell securities issued by these entities based on the merits of the specific investment opportunity.

Investment Techniques

DELAYED DELIVERY TRANSACTIONS. Delayed delivery transactions, also referred to as forward commitments, involve commitments by a Fund to dealers or issuers to acquire or sell municipal securities at a specified future date beyond the customary settlement for such securities. These commitments may fix the payment price and interest rate to be received or paid on the investment. Each Fund may purchase municipal securities on a delayed delivery basis to the extent it can anticipate having available cash on settlement date. Delayed delivery agreements will not be used as a speculative or leveraging technique.

Investment in municipal securities on a delayed delivery basis may increase a Fund's exposure to market fluctuation and may increase the possibility that the Fund will incur short-term gains subject to federal taxation or short-term losses if the Fund must engage in portfolio transactions in order to honor a delayed delivery commitment. Until the settlement date, a Fund will segregate liquid assets of a dollar value sufficient at all times to make payment for the delayed delivery transactions. Such segregated liquid assets will be marked-to-market daily, and the amount segregated will be increased if necessary to maintain adequate coverage of the delayed delivery commitments. No additional delayed delivery agreements or when-issued commitments (as described below) will be made by a Fund if, as a result, more than 25% of the Fund's total assets would become so committed.

The delayed delivery municipal securities, which will not begin to accrue interest or dividends until the settlement date, will be recorded as an asset of a Fund and will be subject to the risk of market fluctuation. The purchase price of the delayed delivery municipal securities is a liability of a Fund until

13

settlement. Absent extraordinary circumstances, a Fund will not sell or otherwise transfer the delayed delivery securities prior to settlement.

A Fund may enter into buy/sell back transactions (a form of delayed delivery agreement). In a buy-sell back transaction, a Fund enters a trade to sell securities at one price and simultaneously enters a trade to buy the same securities at another price for settlement at a future date.

WHEN-ISSUED SECURITIES. Each Fund may purchase when-issued securities. Purchasing municipal securities on a "when-issued" basis means that the date for delivery of and payment for the securities is not fixed at the date of purchase, but is set after the securities are issued. The payment obligation and, if applicable, the interest rate that will be received on the securities are fixed at the time the buyer enters into the commitment. A Fund will only make commitments to purchase such securities with the intention of actually acquiring such securities, but the Fund may sell these securities before the settlement date if it is deemed advisable.

Securities purchased on a when-issued basis and the securities held in a Fund's portfolio are subject to changes in market value based upon the public's perception of the creditworthiness of the issuer and, if applicable, changes in the level of interest rates. Therefore, if a Fund is to remain substantially fully invested at the same time that it has purchased securities on a when-issued basis, there will be a possibility that the market value of the Fund's assets will fluctuate to a greater degree. Furthermore, when the time comes for the Fund to meet its obligations under when-issued commitments, the Fund will do so by using then available cash flow, by sale of the segregated liquid assets, by sale of other securities or, although it would not normally expect to do so, by directing the sale of the when-issued securities themselves (which may have a market value greater or less than the Fund's payment obligation).

Investment in securities on a when-issued basis may increase a Fund's exposure to market fluctuation and may increase the possibility that the Fund will incur short-term gains subject to federal taxation or short-term losses if the Fund must sell another security in order to honor a when-issued commitment. If a Fund purchases a when-issued security, the Fund will segregate liquid assets in an amount equal to the when-issued commitment. Such segregated liquid assets will be marked-to-market daily, and the amount segregated will be increased if necessary to maintain adequate coverage of the Fund's when-issued commitments. No additional delayed delivery agreements (as described above) or when-issued commitments will be made by a Fund if, as a result, more than 25% of the Fund's total assets would become so committed.

SHORT SALES. AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund may engage in short sales. A short sale is effected when it is believed that the price of a particular security will decline, and involves the sale of a security which a Fund does not own in the hope of purchasing the same security at a later date at a lower price. To make delivery to the buyer, a Fund must borrow the security from a broker-dealer through which the short sale is executed, and the broker-dealer delivers the securities, on behalf of the Fund, to the buyer. The broker-dealer is entitled to retain the proceeds from the short sale until a Fund delivers the securities sold short to the broker-dealer. In addition, a Fund is required to pay to the broker-dealer the amount of any dividends paid on shares sold short and may have to pay a premium to borrow the securities.

To secure its obligation to deliver the securities sold short to the broker-dealer, a Fund may be required to deposit cash or liquid securities with the broker in addition to the proceeds from the short sale to meet necessary margin requirements. In addition, a Fund will place in a segregated account with the Fund's custodian an amount of cash or liquid securities equal to the difference, if any, between the current market value of the securities sold short and any cash or liquid securities deposited as collateral with the broker-dealer in connection with the short sale. The amounts deposited with the broker-dealer or segregated with the custodian do not have the effect of limiting the amount of money that the Fund may lose on a short sale.

14

A Fund is said to have a short position in the securities sold short until it delivers to the broker-dealer the securities sold short, at which time such Fund receives the proceeds of the sale. A Fund will normally close out a short position by purchasing on the open market and delivering to the broker-dealer an equal amount of the securities sold short.

A Fund will realize a gain if the price of a security declines between the date of the short sale and the date on which such Fund purchases a security to replace the borrowed security. On the other hand, a Fund will incur a loss if the price of the security increases between those dates. The amount of any gain will be decreased and the amount of any loss increased by any premium or interest that a Fund may be required to pay in connection with a short sale. It should be noted that possible losses from short sales differ from those that could arise from a cash investment in a security in that losses from a short sale may be limitless, while the losses from a cash investment in a security cannot exceed the total amount of a Fund's investment in the security. For example, if a Fund purchases a $10 security, potential loss is limited to $10; however, if a Fund sells a $10 security short, it may have to purchase the security for return to the broker-dealer when the market value of that security is $50, thereby incurring a loss of $40.

A Fund may also make short sales "against the box," meaning that at all times when a short position is open the Fund owns an equal amount of such securities or securities convertible into or exchangeable for, without payment of any further consideration, securities of the same issue as, and in an amount equal to, the securities sold short. To secure its obligation to deliver the securities sold short against the box, a Fund will segregate with its custodian an equal amount of the securities sold short or securities convertible into or exchangeable for an equal amount of such securities. A Fund will not sell a security short if, as a result of such short sale, the aggregate market value of all securities sold short exceeds 10% of the Fund's total assets.

In addition to enabling the Funds to hedge against market risk, short sales and short sales against the box may afford the Funds an opportunity to earn additional current income to the extent the Funds are able to enter into arrangements with broker-dealers though which the short sales are executed to receive income with respect to the proceeds of the short sales during the period the Fund's short positions remain open. There is no assurance that a Fund will be able to enter into such arrangements.

See "Dividends, Distributions and Tax Matters - Tax Matters - Determination of Taxable Income of a Regulated Investment Company."

MARGIN TRANSACTIONS. None of the Funds will purchase any security on margin, except that each Fund may obtain such short-term credits as may be necessary for the clearance of purchases and sales of portfolio securities. The payment by a Fund of initial or variation margin in connection with futures or related options transactions will not be considered the purchase of a security on margin.

INTERFUND LOANS. Each Fund may lend uninvested cash up to 15% of its net assets to other funds advised by Invesco Aim (the "AIM Funds") and each Fund may borrow from other AIM Funds to the extent permitted under such Fund's investment restrictions. During temporary or emergency periods, the percentage of a Fund's net assets that may be loaned to other AIM Funds may be increased as permitted by the SEC. If any interfund borrowings are outstanding, a Fund may not make any additional investments. If a Fund has borrowed from other AIM Funds and has aggregate borrowings from all sources that exceed 10% of such Fund's total assets, such Fund will secure all of its loans from other AIM Funds. The ability of a Fund to lend its securities to other AIM Funds is subject to certain other terms and conditions.

BORROWING. The Funds may borrow money, except as described below, to the extent permitted under the 1940 Act Laws, Interpretations and Exemptions. Such borrowings may be utilized (i) for temporary or emergency purposes; (ii) in anticipation of or in response to adverse market conditions; or, (iii) for cash management purposes. AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund may also borrow money to purchase additional securities when the Invesco Aim and/or the Sub-Advisor deems it advantageous to do so. A Fund may not purchase additional securities when any

15

borrowings from banks exceed 5% of the Fund's total assets or when any borrowings from an AIM Fund are outstanding.

If there are unusually heavy redemptions because of changes in interest rates or Fund performance, or for any other reason, a Fund may have to sell a portion of its investment portfolio at a time when it may be disadvantageous to do so. Selling fund securities under these circumstances may result in a lower net asset value per share or decreased dividend income, or both. The Trust believes that, in the event of abnormally heavy redemption requests, a Fund's borrowing ability would help to mitigate any such effects and could make the forced sale of their portfolio securities less likely. Additionally, the ability of AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund to borrow money for leverage may permit these Funds to access new issuances of securities or assume a defensive strategy in response to an increase in the spread between the bid and ask prices of portfolio securities during specific market events, or settle portfolio transactions.

The Funds may borrow from a bank, broker-dealer, or an AIM Funds. Additionally, the Funds are permitted to temporarily carry a negative or overdrawn balance in their account with their custodian bank. To compensate the custodian bank for such overdrafts, the Funds may either (i) leave funds as a compensating balance in their account so the custodian bank can be compensated by earning interest on such funds; or (ii) compensate the custodian bank by paying it an agreed upon rate.

LENDING PORTFOLIO SECURITIES. Each Fund may lend its portfolio securities (principally to broker-dealers) where such loans are callable at any time and are continuously secured by segregated collateral equal to no less than the market value, determined daily, of the loaned securities. Such collateral will be cash, letters of credit, or debt securities issued or guaranteed by the U.S. Government or any of its agencies. Each Fund may lend portfolio securities to the extent of one-third of its total assets.

A Fund will not have the right to vote securities while they are on loan, but it can call a loan in anticipation of an important vote. The Fund would receive income in lieu of dividends on loaned securities and may, at the same time, generate income on the loan collateral or on the investment of any cash collateral. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly, or in the event of a default by the borrower. The Fund could also experience delays and costs in gaining access to the collateral.

Any cash received as collateral for loaned securities will be invested, in accordance with a Fund's investment guidelines, in short-term money market instruments or Affiliated Money Market Funds. For purposes of determining whether a Fund is complying with its investment policies, strategies and restrictions, the Fund will consider the loaned securities as assets of the Fund, but will not consider any collateral received as a Fund asset.

REPURCHASE AGREEMENTS. Each Fund may engage in repurchase agreement transactions involving the types of securities in which it is permitted to invest. Repurchase agreements are agreements under which a Fund acquires ownership of a security from a broker-dealer or bank that agrees to repurchase the security at a mutually agreed upon time and price (which is higher than the purchase price), thereby determining the yield during the Fund's holding period. A Fund may, however, enter into a "continuing contract" or "open" repurchase agreement under which the seller is under a continuing obligation to repurchase the underlying securities from the Fund on demand and the effective interest rate is negotiated on a daily basis. Repurchase agreements are considered loans by a Fund under the 1940 Act.

If the seller of a repurchase agreement fails to repurchase the security in accordance with the terms of the agreement, the Fund might incur expenses in enforcing its rights, and could experience losses, including a decline in the value of the underlying security and loss of income. In addition, although the Bankruptcy Code and other insolvency laws may provide certain protections for some types of repurchase agreements, if the seller of a repurchase agreement should be involved in bankruptcy or insolvency proceedings, a Fund may incur delay and costs in selling the underlying security and may

16

suffer a loss of principal and interest if the value of the underlying security declines. The securities underlying a repurchase agreement will be marked-to-market every business day so that the value of such securities is at least equal to the investment value of the repurchase agreement, including any accrued interest thereon.

The Funds may invest their cash balances in joint accounts with other AIM Funds for the purpose of investing in repurchase agreements with maturities not to exceed 60 days, and in certain other money market instruments with remaining maturities not to exceed 90 days.

REVERSE REPURCHASE AGREEMENTS. Each Fund may enter into reverse repurchase agreements. Reverse repurchase agreements are agreements that involve the sale by a Fund of securities to financial institutions such as banks and broker-dealers, with an agreement that the Fund will repurchase the securities at an agreed upon price and date. During the reverse repurchase agreement period, a Fund continues to receive interest and principal payments on the securities sold. A Fund may employ reverse repurchase agreements (i) for temporary emergency purposes, such as to meet unanticipated net redemptions so as to avoid liquidating other portfolio securities during unfavorable market conditions; (ii) to cover short-term cash requirements resulting from the timing of trade settlements; or (iii) to take advantage of market situations where the interest income to be earned from the investment of the proceeds of the transaction is greater than the interest expense of the transaction. At the time a Fund enters into a reverse repurchase agreement, it will segregate liquid assets having a dollar value equal to the repurchase price, and will subsequently continually monitor the account to ensure that such equivalent value is maintained at all times. Reverse repurchase agreements involve the risk that the market value of securities to be purchased by the Fund may decline below the price at which it is obligated to repurchase the securities, or that the other party may default on its obligation, so that the Fund is delayed or prevented from completing the transaction. Reverse repurchase agreements are considered borrowings by a Fund under the 1940 Act.

ILLIQUID SECURITIES. Each of AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund may invest up to 15% of its net assets in securities that are illiquid. AIM Tax-Exempt Cash Fund may invest up to 10% of its net assets in securities that are illiquid. Illiquid securities are securities that may not be disposed of within seven days in the normal course of business at the price at which they are valued. Illiquid securities may include securities that are subject to restrictions on resale because they have not been registered under the Securities Act of 1933 (the "1933 Act").

Restricted securities may, in certain circumstances, be resold pursuant to Rule 144A under the 1933 Act, and thus may or may not constitute illiquid securities. Limitations on the resale of restricted securities may have an adverse effect on their marketability, which may prevent a Fund from disposing of them promptly at reasonable prices. A Fund may have to bear the expense of registering such securities for resale, and the risk of substantial delays in effecting such registrations.

RULE 144A SECURITIES. Each Fund may invest in Rule 144A securities. Rule 144A securities are securities which, while privately placed, are eligible for purchase and resale pursuant to Rule 144A under the 1933 Act. This Rule permits certain qualified institutional buyers, such as the Funds, to trade in privately placed securities even though such securities are not registered under the 1933 Act. Invesco Aim and/or Sub-Advisors , under the supervision of the Board, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Funds' restriction on investment in illiquid securities. Determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination Invesco Aim and/or Sub-Advisors will consider the trading markets for the specific security taking into account the unregistered nature of a Rule 144A security. In addition, Invesco Aim and/or Sub-Advisors could consider the (i) frequency of trades and quotes, (ii) number of dealers and potential purchasers, (iii) dealer undertakings to make a market, and (iv) nature of the security and of market place trades (for example, the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer). Invesco Aim and/or Sub-Advisors will also monitor the liquidity of Rule 144A securities and, if as a result of changed conditions, Invesco Aim and/or Sub-Advisors determines that a Rule 144A security is no longer liquid, Invesco Aim and/or Sub-Advisors will review a Fund's holdings of illiquid securities to determine what, if any, action is required to assure that such Fund complies with its

17

restriction on investment in illiquid securities. Investing in Rule 144A securities could increase the amount of each Fund's investments in illiquid securities if qualified institutional buyers are unwilling to purchase such securities.

SALE OF MONEY MARKET SECURITIES. The Funds do not seek profits through short-term trading and will generally hold portfolio securities to maturity. However, Invesco Aim may seek to enhance the yield of the Fund by taking advantage of yield disparities that occur in the money markets. For example, market conditions frequently result in similar securities trading at different prices. Invesco Aim may dispose of any portfolio security prior to its maturity if such disposition and reinvestment of proceeds are expected to enhance yield consistent with Invesco Aim's judgment as to desirable portfolio maturity structure. Invesco Aim may also dispose of any portfolio security prior to maturity to meet redemption requests, and as a result of a revised credit evaluation of the issuer or other circumstances or considerations. The Fund's policy of investing in securities with maturities of 397 days or less will result in high portfolio turnover. Since brokerage commissions are not normally paid on investments of the type made by the Fund, the high turnover should not adversely affect the Fund's net income.

STANDBY COMMITMENTS. AIM High Income Municipal Fund may acquire standby commitments from banks or other municipal securities dealers with respect to securities in its portfolio or that are being purchased by the Fund. Standby commitments generally increase the cost of the acquisition of the underlying security, thereby reducing the yield. Standby commitments depend upon the issuer's ability to fulfill its obligation upon demand. Although no definitive creditworthiness criteria are used for this purpose, Invesco Aim reviews the creditworthiness of the banks and other municipal securities dealers from which AIM High Income Municipal Fund obtains standby commitments in order to evaluate those risks.

Derivatives

PUT AND CALL OPTIONS. AIM High Income Municipal Fund may engage in certain strategies involving options to attempt to manage the risk of their investments or, in certain circumstances, for investment (e.g., as a substitute for investing in securities). Option transactions present the possibility of large amounts of exposure, which may result in a Fund's net asset value being more sensitive to changes in the value of the related investment.

Call Options: A call option gives the purchaser the right to buy the underlying security, contract or foreign currency at the stated exercise price at any time prior to the expiration of the option (or on a specified date if the option is a European style option), regardless of the market price or exchange rate of the security, contract or foreign currency, as the case may be, at the time of exercise. If the purchaser exercises the call option, the writer of a call option is obligated to sell to and deliver the underlying security, contract or foreign currency to the purchaser of the call option.

Put Options: A put option gives the purchaser the right to sell the underlying security, contract or foreign currency at the stated exercise price at any time prior to the expiration date of the option (or on a specified date if the option is a European style option), regardless of the market price or exchange rate of the security, contract or foreign currency, as the case may be, at the time of exercise. If the purchaser exercises the put option, the writer of a put option is obligated to buy the underlying security, contract or foreign currency. The premium paid to the writer is consideration for undertaking the obligations under the option contract. Until an option expires or is offset, the option is said to be "open." When an option expires or is offset, the option is said to be "closed."

Listed Options and Over-The-Counter Options. Options may be either listed on an exchange or traded in over-the-counter ("OTC") markets. Listed options are third-party contracts (i.e., performance of the obligations of the purchaser and seller are guaranteed by the exchange or clearing corporation) and have standardized strike prices and expiration dates. OTC options are two-party contracts with negotiated strike prices and expiration dates. A Fund will not purchase an OTC option unless it believes that daily valuations for such options are readily obtainable. OTC options differ from exchange-traded options in that OTC options are transacted with dealers directly and not through a clearing corporation

18

(which guarantees performance). Consequently, there is a risk of non-performance by the dealer. Since no exchange is involved, OTC options are valued on the basis of an average of the last bid prices obtained from dealers, unless a quotation from only one dealer is available, in which case only that dealer's price will be used. In the case of OTC options, there can be no assurance that a liquid secondary market will exist for any particular option at any specific time. Because purchased OTC options in certain cases may be difficult to dispose of in a timely manner, the Fund may be required to treat some or all of these options (i.e., the market value) as illiquid securities. Although a Fund will enter into OTC options only with dealers that are expected to be capable of entering into closing transactions with it, there is no assurance that the Fund will in fact be able to close out an OTC option position at a favorable price prior to expiration. In the event of insolvency of the dealer, a Fund might be unable to close out an OTC option position at any time prior to its expiration.

Index Options. Index options (or options on securities indices) are similar in many respects to options on securities, except that an index option gives the holder the right to receive, upon exercise, cash instead of securities, if the closing level of the securities index upon which the option is based is greater than, in the case of a call, or less than, in the case of a put, the exercise price of the option. The amount of cash is equal to the difference between the closing price of the index and the exercise price of the call or put times a specified multiple (the "multiplier"), which determines the total dollar value for each point of such difference.

The risks of investment in index options may be greater than options on securities. Because index options are settled in cash, when a Fund writes a call on an index it cannot provide in advance for its potential settlement obligations by acquiring and holding the underlying securities. A Fund can offset some of the risk of writing a call index option by holding a diversified portfolio of securities similar to those on which the underlying index is based. However, the Fund cannot, as a practical matter, acquire and hold a portfolio containing exactly the same securities as underlie the index and, as a result, bears a risk that the value of the securities held will not be perfectly correlated with the value of the index.

Writing Options. A Fund may write put and call options in an attempt to realize, through the receipt of premiums, a greater current return than would be realized on the underlying security, contract, or foreign currency alone. A Fund may only write a call option on a security if it owns an equal amount of such securities or securities convertible into, or exchangeable, without payment of any further consideration, for securities of the same issue as, and equal in amount to, the securities subject to the call option. In return for the premium received for writing a call option, the Fund foregoes the opportunity for profit from a price increase in the underlying security, contract, or foreign currency above the exercise price so long as the option remains open, but retains the risk of loss should the price of the security, contract, or foreign currency decline.

AIM High Income Municipal Fund may write a put option without owning the underlying security if it covers the option as described in the section "Cover." A Fund may only write a put option on a security as part of an investment strategy and not for speculative purposes. In return for the premium received for writing a put option, the Fund assumes the risk that the price of the underlying security, contract, or foreign currency will decline below the exercise price, in which case the put would be exercised and the Fund would suffer a loss.

If an option that a Fund has written expires, it will realize a gain in the amount of the premium; however, such gain may be offset by a decline in the market value of the underlying security, contract or currency during the option period. If a call option is exercised, a Fund will realize a gain or loss from the sale of the underlying security, contract or currency, which will be increased or offset by the premium received. A Fund would write a put option at an exercise price that, reduced by the premium received on the option, reflects the price it is willing to pay for the underlying security, contract or currency. The obligation imposed upon the writer of an option is terminated upon the expiration of the option, or such earlier time at which a Fund effects a closing purchase transaction by purchasing an option (put or call as the case may be) identical to that previously sold.

19

Writing call options can serve as a limited hedge because declines in the value of the hedged investment would be offset to the extent of the premium received for writing the option. Closing transactions may be effected in order to realize a profit on an outstanding call option, to prevent an underlying security, contract or currency from being called or to permit the sale of the underlying security, contract or currency. Furthermore, effecting a closing transaction will permit a Fund to write another call option on the underlying security, contract or currency with either a different exercise price or expiration date, or both.

Pursuant to federal securities rules and regulations, if a Fund writes options it may be required to set aside assets to reduce the risks associated with writing those options. This process is described in more detail below in the section "Cover."

A Fund will not write (sell) options if, immediately after such sale, the aggregate value of securities or obligations underlying the outstanding options exceeds 20% of the Fund's total assets. A Fund will not purchase options if, at the time of the investment, the aggregate premiums paid for the options will exceed 5% of the Fund's total assets.

Purchasing Options. A Fund may purchase a call option for the purpose of acquiring the underlying security, contract or currency for its portfolio. The Fund is not required to own the underlying security in order to purchase a call option, and may only cover the transaction with cash, liquid assets and/or short-term debt securities. Utilized in this fashion, the purchase of call options would enable a Fund to acquire the security, contract or currency at the exercise price of the call option plus the premium paid. So long as it holds such a call option, rather than the underlying security or currency itself, the Fund is partially protected from any unexpected increase in the market price of the underlying security, contract or currency. If the market price does not exceed the exercise price, the Fund could purchase the security on the open market and could allow the call option to expire, incurring a loss only to the extent of the premium paid for the option. Each of the Funds may also purchase call options on underlying securities, contracts or currencies against which it has written other call options. For example, where a Fund has written a call option on an underlying security, rather than entering a closing transaction of the written option, it may purchase a call option with a different exercise strike and/or expiration date that would eliminate some or all of the risk associated with the written call. Used in combinations, these strategies are commonly referred to as "call spreads."

AIM High Income Municipal Fund may only purchase a put option on an underlying security, contract or currency ("protective put") owned by the Fund in order to protect against an anticipated decline in the value of the security, contract or currency. Such hedge protection is provided only during the life of the put option. The premium paid for the put option and any transaction costs would reduce any profit realized when the security, contract or currency is delivered upon the exercise of the put option. Conversely, if the underlying security, contract or currency does not decline in value, the option may expire worthless and the premium paid for the protective put would be lost. A Fund may also purchase put options on underlying securities, contracts or currencies against which it has written other put options. For example, where a Fund has written a put option on an underlying security, rather than entering a closing transaction of the written option, it may purchase a put option with a different exercise price and/or expiration date that would eliminate some or all of the risk associated with the written put. Used in combinations, these strategies are commonly referred to as "put spreads." Likewise, a Fund may write call options on underlying securities, contracts or currencies against which it has purchased protective put options. This strategy is commonly referred to as a "collar."

Straddles. AIM High Income Municipal Fund, for hedging purposes, may write straddles (combinations of put and call options on the same underlying security) to adjust the risk and return characteristics of the Funds' overall position. A possible combined position would involve writing a covered call option at one strike price and buying a call option at a lower price, in order to reduce the risk of the written covered call option in the event of a substantial price increase. Because combined options positions involve multiple trades, they result in higher transaction costs and may be more difficult to open and close out.

20

General Information Regarding Options: The value of an option position will reflect, among other things, the current market value of the underlying investment, the time remaining until expiration, the relationship of the exercise price to the market price of the underlying investment, the price volatility of the underlying investment and general market and interest rate conditions. Options that expire unexercised have no value.

A Fund may effectively terminate its right or obligation under an option by entering into a closing transaction. For example, a Fund may terminate its obligation under a call or put option that it had written by purchasing an identical call or put option, which is known as a closing purchase transaction. Conversely, a Fund may terminate a position in a put or call option it had purchased by writing an identical put or call option, which is known as a closing sale transaction. Closing transactions permit a Fund to realize profits or limit losses on an option position prior to its exercise or expiration.

WARRANTS. AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund may purchase warrants. A warrant is a security that gives the holder the right to purchase securities from the issuer at a specific price within a certain time frame and are similar to call options. The main difference between warrants and call options is that warrants are issued by the company that will issue the underlying security, whereas options are not issued by the company. The purchaser of a warrant expects that the market price of the security will exceed the purchase price of the warrant plus the exercise price of the warrant, thus giving him a profit. Since the market price may never exceed the exercise price before the expiration date of the warrant, the purchaser of the warrant risks the loss of the purchase price of the warrant. Warrants generally trade in the open market and may be sold rather than exercised. Warrants are sometimes sold in unit form with other securities of an issuer. Units of warrants and common stock are often employed to finance young, unseasoned companies. The purchase price of a warrant varies with the exercise price of the warrant, the current market value of the underlying security, the life of the warrant and various other investment factors.

FUTURES CONTRACTS. AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund may purchase Futures Contracts. A Futures Contract is a two-party agreement to buy or sell a specified amount of a specified security or currency (or delivery of a cash settlement price, in the case of an index future) for a specified price at a designated date, time and place (collectively, "Futures Contracts").

Common examples of Futures Contracts that a Fund may engage in include, but are not limited to:

Index Futures: A stock index Futures Contract is an exchange-traded contract that provides for the delivery, at a designated date, time and place, of an amount of cash equal to a specified dollar amount times the difference between the stock index value at the close of trading on the contracts and the price agreed upon in the Futures Contract; no physical delivery of stocks comprising the index is made.

Interest Rate Futures: An interest-rate futures contract is an exchange-traded contact in which the specified underlying security is either an interest-bearing fixed income security or an inter-bank deposit. Two examples of common interest rate futures contracts are U.S. Treasury futures and Eurodollar futures contracts. The specified security for U.S. Treasury futures is a U.S. Treasury security. The specified security for Eurodollar futures is the London Interbank Offered Rate ("Libor") which is a daily reference rate based on the interest rates at which banks offer to lend unsecured funds to other banks in the London wholesale money market.

Security Futures: A security futures contract is an exchange-traded contract to purchase or sell in the future a specified quantity of a security, other than a Treasury security, or a narrow-based securities index at a certain price. Presently, the only available security futures contracts use shares of a single equity security as the specified security.

21

The Funds will only enter into Futures Contracts that are traded (either domestically or internationally) on futures exchanges and are standardized as to maturity date and underlying financial instrument. Futures exchanges and trading thereon in the United States are regulated under the Commodity Exchange Act and by the Commodity Futures Trading Commission ("CFTC"). It should be noted that the Trust, on behalf of each Fund, has claimed an exclusion from the definition of the term "commodity pool operator" under the Commodity Exchange Act and, therefore, is not subject to registration or regulation as a pool operator under the act with respect to the Funds.

Brokerage fees are incurred when a Futures Contract is bought or sold, and margin deposits must be maintained at all times when a Futures Contract is outstanding. "Margin" with respect to Futures Contracts is the amount of funds that must be deposited by a Fund in order to initiate Futures Contracts trading and maintain its open positions in Futures Contracts. A margin deposit made when the Futures Contract is entered ("initial margin") is intended to ensure the Fund's performance under the Futures Contract. The margin required for a particular Futures Contract is set by the exchange on which the Futures Contract is traded and may be significantly modified from time to time by the exchange during the term of the Futures Contract.

Subsequent payments, called "variation margin," received from or paid to the futures commission merchant through which a Fund entered into the Futures Contract will be made on a daily basis as the price of the underlying security, currency, index or futures price fluctuates making the Futures Contract more or less valuable, a process known as marking-to-market.

Closing out an open Futures Contract is effected by entering into an offsetting Futures Contract for the same aggregate amount of the identical financial instrument or currency and the same delivery date. There can be no assurance, however, that a Fund will be able to enter into an offsetting transaction with respect to a particular Futures Contract at a particular time. If a Fund is not able to enter into an offsetting transaction, it will continue to be required to maintain the margin deposits on the Futures Contract.

In addition, if a Fund were unable to liquidate a Futures Contract or an option on a Futures Contract position due to the absence of a liquid secondary market or the imposition of price limits, it could incur substantial losses. The Fund would continue to be subject to market risk with respect to the position. In addition, except in the case of purchased options, the Fund would continue to be required to make daily variation margin payments and might be required to maintain the position being hedged by the Futures Contract or option or to maintain cash or securities in a segregated account.

OPTIONS ON FUTURES CONTRACTS. AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund may purchase options on Futures Contracts. Options on Futures Contracts are similar to options on securities or currencies except that options on Futures Contracts give the purchaser the right, in return for the premium paid, to assume a position in a Futures Contract (a long position if the option is a call and a short position if the option is a put) at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the Futures Contract position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer's Futures Contract margin account. The Funds currently may not invest in any security (including futures contracts or options thereon) that is secured by physical commodities.

Pursuant to federal securities laws and regulations, the Fund's use of Futures Contracts and options on Futures Contracts may require the Fund to set aside assets to reduce the risks associated with using Futures Contracts and options on Futures Contracts. This process is described in more detail below in the section "Cover."

LIMITATIONS ON FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS AND ON

CERTAIN OPTIONS ON CURRENCIES.

A Fund will enter into Futures Contracts for hedging purposes only; that is, Futures Contracts will be sold to protect against a decline in the price of securities or currencies that the Fund owns, or Futures

22

Contracts will be purchased to protect the Fund against an increase in the price of securities or currencies it has committed to purchase or expects to purchase.

FORWARD CURRENCY CONTRACTS. Each Fund may engage in forward currency transactions in anticipation of, or to protect itself against, fluctuations in exchange rates. A forward currency contract is an obligation, usually arranged with a commercial bank or other currency dealer, to purchase or sell a currency for payment in another currency at a future date, which may be any fixed number of days (term) from the date of the forward currency contract and at a price as agreed upon by the parties at the time the contract is entered. A Fund will either accept or make delivery of the currency at the maturity of the forward currency contract. A Fund may also, if its counterparty agrees prior to maturity, enter into a closing transaction involving the purchase or sale of an offsetting contract. Forward currency contracts are traded over-the-counter, and not on organized commodities or securities exchanges. As a result, it may be more difficult to value such contracts, and it may be difficult to enter into closing transactions.

A Fund may enter into forward currency contracts with respect to a specific purchase or sale of a security, or with respect to its portfolio positions generally. When a Fund purchases a security denominated in a foreign currency for settlement in the near future, it may immediately purchase in the forward market the currency needed to pay for and settle the purchase. A Fund may enter into a forward currency contract with respect to the specific purchase or sale of a security denominated in a foreign currency thereby "locking in" an exchange rate between the trade and settlement dates for that purchase or sale transaction. This practice is sometimes referred to as "transaction hedging." Position hedging is the purchase or sale of foreign currency with respect to portfolio security positions denominated or quoted in a foreign currency.

The cost to a Fund of engaging in forward currency contracts varies with factors such as the currencies involved, the length of the contract period and the market conditions then prevailing. Because forward currency contracts are usually entered into on a principal basis, no fees or commissions are involved. The use of forward currency contracts does not eliminate fluctuations in the prices of the underlying securities a Fund owns or intends to acquire, but it does establish a rate of exchange in advance. In addition, while forward currency contract sales limit the risk of loss due to a decline in the value of the hedged currencies, they also limit any potential gain that might result should the value of the currencies increase.

Pursuant to federal securities rules and regulations, a Fund's use of forward currency contracts may require that Fund to set aside assets to reduce the risks associated with using forward currency contracts. This process is described in more detail below in the section "Cover."

COVER. Certain transactions including, but not limited to, credit default swaps, forward currency contracts, futures contracts and options (other than options purchased by a Fund) expose a Fund to an obligation to another party. A Fund will not enter into any such transactions unless, in addition to complying with all the restrictions noted in the disclosure above, it owns either (1) an offsetting position in securities, currencies, or other options, forward currency contracts, or futures contracts or (2) cash, liquid assets and/or short-term debt securities with a value sufficient at all times to cover its potential obligations not covered as provided in (1) above. Each Fund will comply with SEC guidelines regarding cover for these instruments and, if the guidelines so require, set aside cash or liquid assets. To the extent that a credit default swap, futures contract, forward currency contract or option is deemed to be illiquid, the assets used to cover a Fund's obligation will also be treated as illiquid for purposes of determining the Fund's maximum allowable investment in illiquid securities.

To the extent that a purchased option is deemed illiquid, a Fund will treat the market value of the purchased option (i.e., the amount at risk to the Fund) as illiquid, but will not treat the assets used as cover on such transactions as illiquid.

Assets used as cover cannot be sold while the position in the corresponding position is open unless they are replaced with other appropriate assets. If a large portion of a Fund's assets is used for

23

cover or otherwise set aside, it could affect portfolio management or the Fund's ability to meet redemption requests or other current obligations.

GENERAL RISKS OF HEDGING STRATEGIES. The use by AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund of hedging strategies involves special considerations and risks, as described below.

(1) Successful use of hedging transactions depends upon Invesco Aim's and the Sub-Advisors' ability to correctly predict the direction of changes in the value of the applicable markets and securities, contracts and/or currencies. While Invesco Aim and the Sub-Advisors are experienced in the use of these instruments, there can be no assurance that any particular hedging strategy will succeed.

(2) In a hedging transaction, there might be imperfect correlation, or even no correlation, between the price movements of an instrument (such as an option contract) and the price movements of the investments being hedged. For example, if a "protective put" is used to hedge a potential decline in a security and the security does decline in price, the put option's increased value may not completely offset the loss in the underlying security. Such a lack of correlation might occur due to factors unrelated to the value of the investments being hedged, such as changing interest rates, market liquidity, and speculative or other pressures on the markets in which the hedging instrument is traded.

(3) Hedging strategies, if successful, can reduce risk of loss by wholly or partially offsetting the negative effect of unfavorable price movements in the investments being hedged. However, hedging strategies can also reduce opportunity for gain by offsetting the positive effect of favorable price movements in the hedged investments.

(4) There is no assurance that a Fund will use hedging transactions. For example, if a Fund determines that the cost of hedging will exceed the potential benefit to the Fund, the Fund will not enter into such transaction.

Diversification Requirements - AIM Tax-Exempt Cash Fund

As a money market fund, AIM Tax-Exempt Cash Fund is subject to the issuer diversification requirements of Rule 2a-7 under the 1940 Act. For purposes of these issuer diversification requirements with respect to issuers of Municipal Securities, each state (including the District of Columbia and Puerto Rico), territory and possession of the United States, each political subdivision, agency, instrumentality and authority thereof, and each multi-state agency of which a state is a member is a separate "issuer." When the assets and revenues of an agency, authority, instrumentality, or other political subdivision are separate from the government creating the subdivision and the security is backed only by assets and revenues of the subdivision, such subdivision would be deemed to be the sole issuer. Similarly, in the case of an industrial development bond or private activity bond, if such bond is backed only by the assets and revenues of the non-governmental user, then such non-governmental user would be deemed to be the sole issuer.

Rule 2a-7 sets forth two different diversification requirements: one applicable to the issuer of Municipal Securities (provided that such securities are not subject to a demand feature or a guarantee), and one applicable to Municipal Securities with demand features or guarantees.

The issuer diversification requirement provides that the Fund may not invest in the securities of any issuer if, as a result, more than 5% of its total assets would be invested in securities issued by such issuer. If the securities are subject to a demand feature or guarantee, however, they are not subject to this requirement. Moreover, for purposes of this requirement, the issuer of a security is not always the nominal issuer. Instead, in certain circumstances, the underlying obligor of a security is deemed to be the issuer of the security. Such circumstances arise for example when another political subdivision agrees to be ultimately responsible for payments of principal of an interest on a security or when the assets and revenues of a non-governmental user of the facility financed with the Municipal Securities secures repayment of such securities.

24

The diversification requirement applicable to Municipal Securities subject to a demand feature or guarantee provides that, with respect to 75% of its total assets, the Fund may not invest more than 10% of its total assets in securities issued by or subject to demand features or guarantees from the same entity. A demand feature permits the Fund to sell a Municipal Security at approximately its amortized cost value plus accrued interest at specified intervals upon no more than 30 days' notice. A guarantee includes a letter of credit, bond insurance and an unconditional demand feature (provided the demand feature is not provided by the issuer of the security).

FUND POLICIES

FUNDAMENTAL RESTRICTIONS. Each Fund is subject to the following investment restrictions, which may be changed only by a vote of such Fund's outstanding shares, except that only AIM High Income Municipal Fund, AIM Tax-Exempt Cash Fund and AIM Tax-Free Intermediate Fund are subject to restriction (9), (10) and
(11), respectively. Fundamental restrictions may be changed only by a vote of the lesser of (i) 67% or more of the Fund's shares present at a meeting if the holders of more than 50% of the outstanding shares are present in person or represented by proxy, or (ii) more than 50% of the Fund's outstanding shares. Any investment restriction that involves a maximum or minimum percentage of securities or assets (other than with respect to borrowing) shall not be considered to be violated unless an excess over or a deficiency under the percentage occurs immediately after, and is caused by, an acquisition or disposition of securities or utilization of assets by the Fund.

(1) The Fund is a "diversified company" as defined in the 1940 Act. The Fund will not purchase the securities of any issuer if, as a result, the Fund would fail to be a diversified company within the meaning of the 1940 Act, and the rules and regulations promulgated thereunder, as such statute, rules and regulations are amended from time to time or are interpreted from time to time by the SEC staff (collectively, the "1940 Act Laws and Interpretations") or except to the extent that the Fund may be permitted to do so by exemptive order or similar relief (collectively, with the 1940 Act Laws and Interpretations, the "1940 Act Laws, Interpretations and Exemptions"). In complying with this restriction, however, the Fund may purchase securities of other investment companies to the extent permitted by the 1940 Act Laws, Interpretations and Exemptions.

(2) The Fund may not borrow money or issue senior securities, except as permitted by the 1940 Act Laws, Interpretations and Exemptions.

(3) The Fund may not underwrite the securities of other issuers. This restriction does not prevent the Fund from engaging in transactions involving the acquisition, disposition or resale of its portfolio securities, regardless of whether the Fund may be considered to be an underwriter under the 1933 Act.

(4) The Fund will not make investments that will result in the concentration (as that term may be defined or interpreted by the 1940 Act Laws, Interpretations and Exemptions) of its investments in the securities of issuers primarily engaged in the same industry. This restriction does not limit the Fund's investments in (i) obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities, or (ii) tax-exempt obligations issued by governments or political subdivisions of governments, or (iii) with respect to AIM Tax-Exempt Cash Fund, bank instruments. In complying with this restriction, the Fund will not consider a bank-issued guaranty or financial guaranty insurance as a separate security.

(5) The Fund may not purchase real estate or sell real estate unless acquired as a result of ownership of securities or other instruments. This restriction does not prevent the Fund from investing in issuers that invest, deal, or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein.

(6) The Fund may not purchase physical commodities or sell physical commodities unless acquired as a result of ownership of securities or other instruments. This restriction does not prevent the

25

Fund from engaging in transactions involving futures contracts and options thereon or investing in securities that are secured by physical commodities.

(7) The Fund may not make personal loans or loans of its assets to persons who control or are under common control with the Fund, except to the extent permitted by 1940 Act Laws, Interpretations and Exemptions. This restriction does not prevent the Fund from, among other things, purchasing debt obligations, entering into repurchase agreements, loaning its assets to broker-dealers or institutional investors, or investing in loans, including assignments and participation interests.

(8) The Fund may, notwithstanding any other fundamental investment policy or limitation, invest all of its assets in the securities of a single open-end management investment company with substantially the same fundamental investment objectives, policies and restrictions as the Fund.

(9) Under normal circumstances, AIM High Income Municipal Fund will invest at least 80% of the value of its assets (as that term may be defined or interpreted by the 1940 Act Laws, Interpretations and Exemptions) in investments the income from which is exempt from federal income tax under regular tax rules.

(10) Under normal circumstances, AIM Tax-Exempt Cash Fund will invest at least 80% of the value of its assets (as that term may be defined or interpreted by the 1940 Act Laws, Interpretations and Exemptions) in investments the income from which is exempt from federal income tax.

(11) Under normal circumstances, AIM Tax-Free Intermediate Fund will invest at least 80% of the value of its assets (as that term may be defined or interpreted by the 1940 Act Laws, Interpretations and Exemptions) in investments the income from which is exempt from federal income tax.

The investment restrictions set forth above provide each of the Funds with the ability to operate under new interpretations of the 1940 Act or pursuant to exemptive relief from the SEC without receiving prior shareholder approval of the change. Even though each of the Funds has this flexibility, the Board of Trustees has adopted non-fundamental restrictions for each of the Funds relating to certain of these restrictions which Invesco Aim and, when applicable, the Sub-Advisors must follow in managing the Funds. Any changes to these non-fundamental restrictions, which are set forth below, require the approval of the Board of Trustees.

NON-FUNDAMENTAL RESTRICTIONS. The following non-fundamental investment restrictions apply to each of the Funds. They may be changed for any Fund without approval of that Fund's voting securities.

(1) In complying with the fundamental restriction regarding issuer diversification, the Fund will not, with respect to 75% of its total assets (and for AIM Tax-Exempt Cash Fund, with respect to 100% of its total assets), purchase the securities of any issuer (other than securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities and securities issued by other investment companies), if, as a result, (i) more than 5% of the Fund's total assets would be invested in the securities of that issuer, except as permitted by Rule 2a-7 under the 1940 Act, or (ii) the Fund would hold more than 10% of the outstanding voting securities of that issuer. The Fund may purchase securities of other investment companies as permitted the 1940 Act Laws, Interpretations and Exemptions.

(2) In complying with the fundamental restriction regarding borrowing money and issuing senior securities, the Fund may borrow money in an amount not exceeding 33 1/3% of its total assets (including the amount borrowed) less liabilities (other than borrowings). The Fund may borrow from banks, broker-dealers or an AIM Fund. The Fund may not borrow for leveraging except that AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund may borrow from banks for leveraging in an amount not exceeding 5% of the Fund's total assets (not including the amount borrowed) at the time the borrowing is made. The Fund may borrow for temporary or emergency purposes, in anticipation of or in response to adverse market conditions, or for cash management purposes. The Fund may not purchase additional securities when any borrowings from banks exceed 5% of the Fund's total assets or when any borrowings from an AIM Fund are outstanding.

26

(3) In complying with the fundamental restriction regarding industry concentration, the Fund may invest up to 25% of its total assets in the securities of issuers whose principal business activities are in the same industry.

(4) In complying with the fundamental restriction with regard to making loans, the Fund may lend up to 33 1/3% of its total assets and may lend money to an AIM Fund, on such terms and conditions as the SEC may require in an exemptive order.

(5) Notwithstanding the fundamental restriction with regard to investing all assets in an open-end fund, the Fund may not invest all of its assets in the securities of a single open-end management investment company with the same fundamental investment objectives, policies and restrictions as the Fund.

(6) Notwithstanding the fundamental restriction with regard to engaging in transactions involving futures contracts and options thereon or investing in securities that are secured by physical commodities, the Fund currently may not invest in any security (including futures contracts or options thereon) that is secured by physical commodities.

(7) The Fund may not acquire any securities of registered open-end investment companies or registered unit investment trusts in reliance on Sections 12(d)(1)(F) or 12(d)(1)(G) of the 1940 Act.

The Funds do not consider currencies or other financial commodities or contracts and financial instruments to be physical commodities (which include, for example, oil, precious metals and grains). Accordingly, the Funds will interpret the restriction and the related non-fundamental restriction to permit the Funds, subject to each Fund's investment objectives and general investment policies (as stated in the Funds' prospectuses and herein), to invest directly in foreign currencies and other financial commodities and to purchase, sell or enter into commodity futures contracts and options thereon, foreign currency forward contracts, foreign currency options, currency-, commodity- and financial instrument-related swap agreements, hybrid instruments, interest rate or securities-related or foreign currency-related hedging instruments or other currency-, commodity- or financial instrument-related derivatives, subject to compliance with any applicable provisions of the federal securities or commodities laws. The Funds also will interpret their fundamental restriction regarding purchasing and selling physical commodities and their related non-fundamental restriction to permit the Funds to invest in exchange-traded funds that invest in physical and/or financial commodities, subject to the limits described in the Funds' prospectuses and herein.

ADDITIONAL NON-FUNDAMENTAL POLICIES. As non-fundamental policies:

(1) For purposes of the fundamental restriction regarding issuer diversification for AIM Tax-Free Intermediate Fund, AIM High Income Municipal Fund and AIM Tax-Exempt Cash Fund, each Fund will regard each state and political subdivision, agency or instrumentality, and each multi-state agency of which such state is a member, as a separate issuer.

(2) Under normal circumstances, AIM High Income Municipal Fund will invest at least 80% of the value of its assets (as that term may be defined or interpreted by the 1940 Act Laws, Interpretations and Exemptions) in investments the income from which will not constitute an item of tax preference under the AMT rules.

(3) For purposes of AIM Tax-Free Intermediate Fund's fundamental restriction with regard to investing at least 80% of its assets, in investments the income from which is exempt from federal income tax, the term "assets" shall mean net assets, plus the amount of any borrowings for investment purposes.

27

TEMPORARY DEFENSIVE POSITIONS

In anticipation of or in response to adverse market or other conditions, or atypical circumstances such as unusually large cash inflows or redemptions, the Funds may temporarily hold all or a portion of their assets in cash, cash equivalents or high-quality debt instruments (including shares of Affiliated Money Market Funds).

Cash equivalents include money market instruments (such as certificates of deposit, time deposits, banker's acceptances from U.S. or foreign banks, and repurchase agreements), shares of affiliated money market funds or high-quality debt obligations (such as U.S. Government obligations, commercial paper, master notes and other short-term corporate instruments and municipal obligations).

PORTFOLIO TURNOVER

For the fiscal year ended March 31, 2008 and 2007, the portfolio turnover rates for each Fund, except for AIM Tax-Exempt Cash Fund, are presented in the table below. Unless otherwise indicated, variations in turnover rate may be due to a fluctuating volume of shareholder purchase and redemption orders, market conditions and/or changes in Invesco Aim's investment outlook.

        TURNOVER RATES           2008   2007
        --------------           ----   ----
AIM High Income Municipal Fund    23%    10%
AIM Tax-Free Intermediate Fund    19     11

You may also obtain the publicly available portfolio holdings information described above by contacting us at 1-800-959-4246.

SELECTIVE DISCLOSURE OF PORTFOLIO HOLDINGS PURSUANT TO NON-DISCLOSURE AGREEMENT. Employees of Invesco Aim and its affiliates may disclose non-public full portfolio holdings on a selective basis only if the Internal Compliance Controls Committee (the "ICCC") of Invesco Aim Management Group Inc. ("Invesco Aim Management") approves the parties to whom disclosure of non-public full portfolio holdings will be made. The ICCC must determine that the proposed selective disclosure will be made for legitimate business purposes of the applicable Fund and address any perceived conflicts of interest between shareholders of such Fund and Invesco Aim or its affiliates as part of granting its approval.

The Board exercises continuing oversight of the disclosure of Fund portfolio holdings by (1) overseeing the implementation and enforcement of the Holdings Disclosure Policy and the AIM Funds Code of Ethics by the Chief Compliance Officer (or his designee) of Invesco Aim and the AIM Funds and (2) considering reports and recommendations by the Chief Compliance Officer concerning any material compliance matters (as defined in Rule 38a-1 under the 1940 Act and Rule 206(4)-7 under the Investment Advisers Act of 1940, as amended) that may arise in connection with the Holdings Disclosure Policy. Pursuant to the Holdings Disclosure Policy, the Board reviews the types of situations in which Invesco Aim provides such selective disclosure and approves situations involving perceived conflicts of interest between shareholders of the applicable Fund and Invesco Aim or its affiliates brought to the Board's attention by Invesco Aim.

Invesco Aim discloses non-public full portfolio holdings information to the following persons in connection with the day-to-day operations and management of the AIM Funds:

- Attorneys and accountants;

- Securities lending agents;

- Lenders to the AIM Funds;

- Rating and rankings agencies;

- Persons assisting in the voting of proxies;

- AIM Funds' custodians;

- The AIM Funds' transfer agent(s) (in the event of a redemption in kind);

- Pricing services, market makers, or other persons who provide systems or software support in connection with AIM Funds' operations (to determine the price of securities held by an AIM Fund);

- Financial printers;

- Brokers identified by the AIM Funds' portfolio management team who provide execution and research services to the team; and

29

- Analysts hired to perform research and analysis to the AIM Funds' portfolio management team.

In many cases, Invesco Aim will disclose current portfolio holdings on a daily basis to these persons. In these situations, Invesco Aim has entered into non-disclosure agreements which provide that the recipient of the portfolio holdings will maintain the confidentiality of such portfolio holdings and will not trade on such information ("Non-disclosure Agreements"). Please refer to Appendix B for a list of examples of persons to whom Invesco Aim provides non-public portfolio holdings on an ongoing basis.

Invesco Aim will also disclose non-public portfolio holdings information if such disclosure is required by applicable laws, rules or regulations, or by regulatory authorities having jurisdiction over Invesco Aim and its affiliates or the Funds.

The Holdings Disclosure Policy provides that Invesco Aim will not request, receive or accept any compensation (including compensation in the form of the maintenance of assets in any Fund or other mutual fund or account managed by Invesco Aim or one of its affiliates) for the selective disclosure of portfolio holdings information.

DISCLOSURE OF CERTAIN PORTFOLIO HOLDINGS AND RELATED INFORMATION WITHOUT NON-DISCLOSURE AGREEMENT. Invesco Aim and its affiliates that provide services to the Funds, Sub-Advisors and each of their employees may receive or have access to portfolio holdings as part of the day to day operations of the Funds.

From time to time, employees of Invesco Aim and its affiliates may express their views orally or in writing on one or more of the Funds' portfolio securities or may state that a Fund has recently purchased or sold, or continues to own, one or more securities. The securities subject to these views and statements may be ones that were purchased or sold since a Fund's most recent quarter-end and therefore may not be reflected on the list of the Fund's most recent quarter-end portfolio holdings disclosed on the website. Such views and statements may be made to various persons, including members of the press, brokers and other financial intermediaries that sell shares of the Funds, shareholders in the applicable Fund, persons considering investing in the applicable Fund or representatives of such shareholders or potential shareholders, such as fiduciaries of a 401(k) plan or a trust and their advisers, and other entities for which Invesco Aim or its affiliates provides or may provide investment advisory services. The nature and content of the views and statements provided to each of these persons may differ.

From time to time, employees of Invesco Aim and its affiliates also may provide oral or written information ("portfolio commentary") about a Fund, including, but not limited to, how the Fund's investments are divided among various sectors, industries, countries, investment styles and capitalization sizes, and among stocks, bonds, currencies and cash, security types, bond maturities, bond coupons and bond credit quality ratings. This portfolio commentary may also include information on how these various weightings and factors contributed to Fund performance. Invesco Aim may also provide oral or written information ("statistical information") about various financial characteristics of a Fund or its underlying portfolio securities including, but not limited to, alpha, beta, R-squared, coefficient of determination, duration, maturity, information ratio, sharpe ratio, earnings growth, payout ratio, price/book value, projected earnings growth, return on equity, standard deviation, tracking error, weighted average quality, market capitalization, percent debt to equity, price to cash flow, dividend yield or growth, default rate, portfolio turnover, and risk and style characteristics. This portfolio commentary and statistical information about a Fund may be based on the Fund's portfolio as of the most recent quarter-end or the end of some other interim period, such as month-end. The portfolio commentary and statistical information may be provided to various persons, including those described in the preceding paragraph. The nature and content of the information provided to each of these persons may differ.

DISCLOSURE OF PORTFOLIO HOLDINGS BY TRADERS. Additionally, employees of Invesco Aim and its affiliates may disclose one or more of the portfolio securities of a Fund when purchasing and selling securities through broker-dealers, requesting bids on securities, obtaining price quotations on securities,

30

or in connection with litigation involving the Funds' portfolio securities. Invesco Aim does not enter into formal Non-disclosure Agreements in connection with these situations; however, the Funds would not continue to conduct business with a person who Invesco Aim believed was misusing the disclosed information.

DISCLOSURE OF PORTFOLIO HOLDINGS OF OTHER INVESCO AIM-MANAGED PRODUCTS. Invesco Aim and its affiliates manage products sponsored by companies other than Invesco Aim, including investment companies, offshore funds, and separate accounts. In many cases, these other products are managed in a similar fashion to certain AIM Funds (as defined herein) and thus have similar portfolio holdings. The sponsors of these other products managed by Invesco Aim and its affiliates may disclose the portfolio holdings of their products at different times than Invesco Aim discloses portfolio holdings for the AIM Funds.

Invesco Aim provides portfolio holdings information for portfolios of AIM Variable Insurance Funds (the "Insurance Funds") to insurance companies whose variable annuity and variable life insurance accounts invest in the Insurance Funds ("Insurance Companies"). Invesco Aim may disclose portfolio holdings information for the Insurance Funds to Insurance Companies with which Invesco Aim has entered into Non-disclosure Agreements up to five days prior to the scheduled dates for Invesco Aim's disclosure of similar portfolio holdings information for other AIM Funds on http://www.invescoaim.com. Invesco Aim provides portfolio holdings information for the Insurance Funds to such Insurance Companies to allow them to disclose this information on their websites at approximately the same time that Invesco Aim discloses portfolio holdings information for the other AIM Funds on its website. Invesco Aim manages the Insurance Funds in a similar fashion to certain other AIM Funds and thus the Insurance Funds and such other AIM Funds have similar portfolio holdings. Invesco Aim does not disclose the portfolio holdings information for the Insurance Funds on its website, and not all Insurance Companies disclose this information on their websites.

Trustee Ownership of Fund Shares

The dollar range of equity securities beneficially owned by each trustee
(i) in the Fund and (ii) on an aggregate basis, in all registered investment companies overseen by the trustee within the AIM Funds complex, is set forth in Appendix C.

COMPENSATION

Each trustee who is not affiliated with Invesco Aim is compensated for his or her services according to a fee schedule which recognizes the fact that such trustee also serves as a trustee of other AIM Funds. Each such trustee receives a fee, allocated among the AIM Funds for which he or she serves as a director or trustee, which consists of an annual retainer component and a meeting fee component. The Chair of the Board and Chairs and Vice Chairs of certain committees receive additional compensation from their services.

Information regarding compensation paid or accrued for each trustee of the Trust who was not affiliated with Invesco Aim during the year ended December 31, 2007 is found in Appendix D.

Retirement Plan For Trustees

The trustees have adopted a retirement plan for the trustees of the Trust who are not affiliated with Invesco Aim.

The trustees have also adopted a retirement policy that permits each non-Invesco Aim-affiliated trustee to serve until December 31 of the year in which the trustee turns 75. A majority of the trustees may extend from time to time the retirement date of a trustee.

Annual retirement benefits are available to each non-Invesco Aim-affiliated trustee of the Trust and/or other AIM Funds (each, a "Covered Fund") who has at least five years of credited service as a trustee (including service to a predecessor fund) for a Covered Fund. Effective January 1, 2006, for retirements after December 31, 2005, the retirement benefits will equal 75% of the trustee's annual retainer paid to or accrued by any Covered Fund with respect to such trustee during the twelve-month period prior to retirement, including the amount of any retainer deferred under a separate deferred compensation agreement between the Covered Fund and the trustee. The amount of the annual retirement benefit does not include additional compensation paid for Board meeting fees or compensation paid to the Chair of the Board and the Chairs and Vice Chairs of certain Board committees, whether such amounts are paid directly to the trustee or deferred. The annual retirement benefit is payable in quarterly installments for a number of years equal to the lesser of (i) sixteen years or (ii) the number of such trustee's credited years of service. If a trustee dies prior to receiving the full amount of retirement benefits, the remaining payments will be made to the deceased trustee's designated beneficiary for the same length of time that the trustee would have received the payments, based on his or her service. A trustee must have attained the age of 65 (60 in the event of death or disability) to receive any retirement benefit. A trustee may make an irrevocable election to commence payment of retirement benefits upon retirement from the Board before age 72, subject to a reduction for early payment.

Deferred Compensation Agreements

Messrs. Crockett, Edward K. Dunn (a former trustee), Fields, Frischling and Drs. Mathai-Davis and Soll (for purposes of this paragraph only, the "Deferring Trustees") have each executed a Deferred Compensation Agreement (collectively, the "Compensation Agreements"). Pursuant to the Compensation Agreements, the Deferring Trustees have the option to elect to defer receipt of up to 100% of their compensation payable by the Trust, and such amounts are placed into a deferral account and deemed to be invested in one or more AIM Funds selected by the Deferring Trustees. Distributions from the

35

Deferring Trustees' deferral accounts will be paid in cash, generally in equal quarterly installments over a period of up to ten (10) years (depending on the Compensation Agreement) beginning on the date selected under the Compensation Agreement. If a Deferring Trustee dies prior to the distribution of amounts in his or her deferral account, the balance of the deferral account will be distributed to his or her designated beneficiary. The Compensation Agreements are not funded and, with respect to the payments of amounts held in the deferral accounts, the Deferring Trustees have the status of unsecured creditors of the Trust and of each other AIM Fund from which they are deferring compensation.

Purchase of Class A Shares of the Funds at Net Asset Value

The trustees and other affiliated persons of the Trust may purchase Class A shares of the AIM Funds without paying an initial sales charge. Invesco Aim Distributors, Inc. ("Invesco Aim Distributors") permits such purchases because there is a reduced sales effort involved in sales to such purchasers, thereby resulting in relatively low expenses of distribution. For a complete description of the persons who will not pay an initial sales charge on purchases of Class A shares of the Funds, see "Purchase, Redemption and Pricing of Shares - Purchase and Redemption of Shares - Purchases of Class A Shares Class A3 Shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund and AIM Cash Reserve Shares of AIM Money Market Fund - Purchases of Class A Shares at Net Asset Value."

CODES OF ETHICS

Invesco Aim, the Trust, Invesco Aim Distributors and the Sub-Advisors have adopted Codes of Ethics which apply to all AIM Fund trustees and officers, and employees of Invesco Aim, the Sub-Advisors and their affiliates, and govern, among other things, personal trading activities of all such persons. The Codes of Ethics are intended to address conflicts of interest with the Trust that may arise from personal trading, including personal trading in most of the funds within The AIM Family of Funds--Registered Trademark--. Personal trading, including personal trading involving securities that may be purchased or held by a fund within The AIM Family of Funds--Registered Trademark--, is permitted under the Code subject to certain restrictions; however, employees are required to pre-clear security transactions with the applicable Compliance Officer or a designee and to report transactions on a regular basis.

PROXY VOTING POLICIES

The Board has delegated responsibility for decisions regarding proxy voting for securities held by each Fund to Invesco Aim, the Fund's investment advisor. Invesco Aim will vote such proxies in accordance with its proxy policies and procedures, which have been reviewed and approved by the Board, and which are found in Appendix E.

Any material changes to the proxy policies and procedures will be submitted to the Board for approval. The Board will be supplied with a summary quarterly report of each Fund's proxy voting record.

Information regarding how the Funds voted proxies related to their portfolio securities during the 12 months ended June 30, 2007 is available at our web site, http://www.invescoaim.com. This information is also available at the SEC web site, http://www.sec.gov.

CONTROL PERSONS AND PRINCIPAL HOLDERS OF SECURITIES

Information about the ownership of each class of each Fund's shares by beneficial or record owners of such Fund and by trustees and officers as a group is found in Appendix F. A shareholder who owns beneficially 25% or more of the outstanding shares of a Fund is presumed to "control" that Fund.

Invesco Aim currently waives such fee, and has agreed to seek Board approval prior to its receipt of all or a portion of such fee.

SERVICE AGREEMENTS

ADMINISTRATIVE SERVICES AGREEMENT. Invesco Aim and the Trust have entered into a Master Administrative Services Agreement ("Administrative Services Agreement") pursuant to which Invesco Aim may perform or arrange for the provision of certain accounting and other administrative services to each Fund which are not required to be performed by Invesco Aim under the Advisory Agreement. The Administrative Services Agreement provides that it will remain in effect and continue from year to year only if such continuance is specifically approved at least annually by the Board, including the independent trustees, by votes cast in person at a meeting called for such purpose. Under the Administrative Services Agreement, Invesco Aim is entitled to receive from the Funds reimbursement of its costs or such reasonable compensation as may be approved by the Board. Currently, Invesco Aim is reimbursed for the services of the Trust's principal financial officer and her staff, and any expenses related to fund accounting services.

Administrative services fees paid to Invesco Aim by each Fund for the last three fiscal years ended March 31 are found in Appendix I.

OTHER SERVICE PROVIDERS

TRANSFER AGENT. Invesco Aim Investment Services, Inc. ("Invesco Aim Investment Services"), 11 Greenway Plaza, Suite 100, Houston, Texas 77046, a wholly-owned subsidiary of Invesco Aim, is the Trust's transfer agent.

The Transfer Agency and Service Agreement (the "TA Agreement") between the Trust and Invesco Aim Investment Services provides that Invesco Aim Investment Services will perform certain services related to the servicing of shareholders of the Funds. Other such services may be delegated or sub-contracted to third party intermediaries. For servicing accounts holding Class A, A3, B, C, P, R, AIM Cash Reserve and Investor Class Shares, the TA Agreement provides that the Trust, on behalf of the Funds, will pay Invesco Aim Investment Services an annual fee per open shareholder account plus certain out of pocket expenses. This fee is paid monthly at the rate of 1/12 of the annual rate and is based upon the number of open shareholder accounts during each month. For servicing accounts holding Institutional Class Shares, the TA Agreement provides that the Trust, on behalf of the Funds, will pay Invesco Aim Investment Services a fee per trade executed, to be billed monthly plus certain out of pocket expenses. In addition, all fees payable by Invesco Aim Investment Services or its affiliates to third party intermediaries who service accounts pursuant to sub-transfer agency, omnibus account services and sub-accounting agreements are charged back to the Funds, subject to certain limitations and approved by the Board of the Trust. These payments are made in consideration of services that would otherwise be provided by Invesco Aim Investment Services if the accounts serviced by such intermediaries were serviced by Invesco Aim Investment Services directly. For more information regarding such payments to intermediaries, see the discussion under "Administrative and Processing Support Payments" below.

SUB-TRANSFER AGENT. AFMI, 5140 Yonge Street, Suite 900, Toronto, Ontario M2N6X7, a wholly owned, indirect subsidiary of Invesco, provides services to the Trust as a sub-transfer agent, pursuant to an agreement between AFMI and Invesco Aim Investment Services. The Trust does not pay a fee to AFMI for these services. Rather AFMI is compensated by Invesco Aim Investment Services, as a sub-contractor.

CUSTODIANS. The Bank of New York (the "Custodian"), 2 Hanson Place, Brooklyn, New York 11217-1431, is custodian of all securities and cash of the Funds. JPMorgan Chase Bank, N.A., 712 Main, Houston, Texas 77002, serves as sub-custodian for purchases of shares of the Funds.

Under its contract with the Trust, the Custodian maintains the portfolio securities of the Funds, administers the purchases and sales of portfolio securities, collects interest and dividends and other distributions made on the securities held in the portfolios of the Funds and performs other ministerial

40

duties. These services do not include any supervisory function over management or provide any protection against any possible depreciation of assets.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM. The Fund's independent registered public accounting firm is responsible for auditing the financial statements of the Funds. The Audit Committee of the Board has appointed PricewaterhouseCoopers LLP, 1201 Louisiana, Suite 2900, Houston, TX 77002, as the independent registered public accounting firm to audit the Funds' financial statements. Such appointment was ratified and approved by the Board.

COUNSEL TO THE TRUST. Legal matters for the Trust have been passed upon by Stradley Ronon Stevens & Young LLP, 2600 One Commerce Square, Philadelphia, Pennsylvania 19103.

BROKERAGE ALLOCATION AND OTHER PRACTICES

The Sub-Advisors have adopted compliance procedures that cover, among other items, brokerage allocation and other trading practices. If all or a portion of a Fund's assets are managed by one or more Sub-Advisors, the decision to buy and sell securities and broker selection will be made by the Sub-Advisor for the assets it manages. Unless specifically noted, the Sub-Advisors' procedures do not materially differ from Invesco Aim's procedures discussed below.

BROKERAGE TRANSACTIONS

Invesco Aim or the Sub-Advisor makes decisions to buy and sell securities for each Fund, selects broker-dealers, (each, a "Broker"), effects the Funds' investment portfolio transactions, allocates brokerage fees in such transactions and, where applicable, negotiates commissions and spreads on transactions. Invesco Aim and the Sub-Advisor's primary consideration in effecting a security transaction is to obtain best execution, which is defined as prompt and efficient execution of the transaction at the best obtainable price with payment of commissions, mark-ups or mark-downs which are reasonable in relation to the value of the brokerage services provided by the Broker. While Invesco Aim and the Sub-Advisors seek reasonably competitive commission rates, the Funds may not pay the lowest commission or spread available. See "Broker Selection" below.

Some of the securities in which the Funds invest are traded in over-the-counter markets. Portfolio transactions placed in such markets may be effected on a principal basis at net prices without commissions, but which include compensation to the Broker in the form of a mark up or mark down, or on an agency basis, which involves the payment of negotiated brokerage commissions to the Broker, including electronic communication networks. Purchases of underwritten issues include a commission or concession paid by the issuer (not the Funds) to the underwriter. Purchases of money market instruments may be made directly from issuers without the payment of commissions.

Traditionally, commission rates have not been negotiated on stock markets outside the United States. Although in recent years many overseas stock markets have adopted a system of negotiated rates, a number of markets maintain an established schedule of minimum commission rates.

Brokerage commissions, if any, paid by the Funds for the last three fiscal years ended March 31 are found in Appendix J.

COMMISSIONS

During the last three fiscal years ended March 31, none of the Funds paid brokerage commissions to Brokers affiliated with the Funds, Invesco Aim, Invesco Aim Distributors, the Sub-Advisors or any affiliates of such entities.

The Funds may engage in certain principal and agency transactions with banks and their affiliates that own 5% or more of the outstanding voting securities of an AIM Fund, provided the conditions of an

41

exemptive order received by the AIM Funds from the SEC are met. In addition, a Fund may purchase or sell a security from or to certain other AIM Funds or accounts (and may invest in Affiliated Money Market Funds) provided the Funds follow procedures adopted by the Boards of the various AIM Funds, including the Trust. These inter-fund transactions do not generate brokerage commissions but may result in custodial fees or taxes or other related expenses.

BROKER SELECTION

Invesco Aim's primary consideration in selecting Brokers to execute portfolio transactions for a Fund is to obtain best execution. In selecting a Broker to execute a portfolio transaction in equity securities for a Fund, Invesco Aim considers the full range and quality of a Broker's services, including the value of research and/or brokerage services provided, execution capability, commission rate, willingness to commit capital, anonymity and responsiveness. Invesco Aim's primary consideration when selecting a Broker to execute a portfolio transaction in fixed income securities for a Fund is the Broker's ability to deliver or sell the relevant fixed income securities; however, Invesco Aim will also consider the various factors listed above. In each case, the determinative factor is not the lowest commission or spread available but whether the transaction represents the best qualitative execution for the Fund. Invesco Aim will not select Brokers based upon their promotion or sale of Fund shares.

In choosing Brokers to execute portfolio transactions for the Funds, Invesco Aim may select Brokers that provide brokerage and/or research services ("Soft Dollar Products") to the Funds and/or the other accounts over which Invesco Aim and its affiliates have investment discretion. Section 28(e) of the Securities Exchange Act of 1934, as amended provides that Invesco Aim, under certain circumstances, lawfully may cause an account to pay a higher commission than the lowest available. Under Section 28(e)(1), Invesco Aim must make a good faith determination that the commissions paid are "reasonable in relation to the value of the brokerage and research services provided ... viewed in terms of either that particular transaction or [Invesco Aim's] overall responsibilities with respect to the accounts as to which [it] exercises investment discretion." The services provided by the Broker also must lawfully and appropriately assist Invesco Aim in the performance of its investment decision-making responsibilities. Accordingly, a Fund may pay a Broker higher commissions than those available from another Broker in recognition of such Broker's provision of Soft Dollar Products to Invesco Aim.

Invesco Aim faces a potential conflict of interest when it uses client trades to obtain Soft Dollar Products. This conflict exists because Invesco Aim is able to use the Soft Dollar Products to manage client accounts without paying cash for the Soft Dollar Products, which reduces Invesco Aim's expenses to the extent that Invesco Aim would have purchased such products had they not been provided by Brokers. Section 28(e) permits Invesco Aim to use Soft Dollar Products for the benefit of any account it manages. Certain Invesco Aim-managed accounts may generate soft dollars used to purchase Soft Dollar Products that ultimately benefit other Invesco Aim-managed accounts, effectively cross subsidizing the other Invesco Aim-managed accounts that benefit directly from the product. Invesco Aim may not use all of the Soft Dollar Products provided by Brokers through which a Fund effects securities transactions in connection with managing such Fund.

Invesco Aim and certain of its affiliates presently engage in the following instances of cross-subsidization:

1. Fixed income funds normally do not generate soft dollar commissions to pay for Soft Dollar Products. Therefore, soft dollar commissions used to pay for Soft Dollar Products which are used to manage certain fixed income AIM Funds are generated entirely by equity AIM Funds and other equity client accounts managed by Invesco Aim or Invesco Aim Capital Management, Inc. ("Invesco Aim Capital"), a subsidiary of Invesco Aim. In other words, certain fixed income AIM Funds are cross-subsidized by the equity AIM Funds, in that the fixed income AIM Funds receive the benefit of Soft Dollar Products services for which they do not pay.

42

2. The investment models used to manage many of the AIM Funds are also used to manage other accounts of Invesco Aim and/or Invesco Aim Capital. The Soft Dollar Products obtained through the use of soft dollar commissions generated by the transactions of the AIM Funds and/or other accounts managed by Invesco Aim and/or Invesco Aim Capital are used to maintain the investment models relied upon by both of these advisory affiliates.

This type of cross-subsidization occurs in both directions. For example, soft dollar commissions generated by transactions of the AIM Funds and/or other accounts managed by Invesco Aim are used for Soft Dollar Products which may benefit those AIM Funds and/or accounts as well as accounts managed by Invesco Aim Capital. Additionally, soft dollar commissions generated by transactions of accounts managed by Invesco Aim Capital are used for Soft Dollar Products which may benefit those accounts as well as accounts managed by Invesco Aim. In certain circumstances, Invesco Aim Capital accounts may indicate that their transactions should not be used to generate soft dollar commissions but may still receive the benefits of Soft Dollar Products received by Invesco Aim or Invesco Aim Capital.

3. Some of the common investment models used to manage various AIM Funds and other accounts of Invesco Aim and/or Invesco Aim Capital are also used to manage accounts of Invesco Aim Private Asset Management, Inc. ("IAPAM"), another Invesco Aim subsidiary. The Soft Dollar Products obtained through the use of soft dollar commissions generated by the transactions of the Funds and/or other accounts managed by Invesco Aim and/or Invesco Aim Capital are used to maintain the investment models relied upon by Invesco Aim, Invesco Aim Capital and IAPAM. This cross-subsidization occurs in only one direction. Most of IAPAM's accounts do not generate soft dollar commissions which can be used to purchase Soft Dollar Products. The soft dollar commissions generated by transactions of the Funds and/or other accounts managed by Invesco Aim and/or Invesco Aim Capital are used for Soft Dollar Products which may benefit the accounts managed by Invesco Aim, Invesco Aim Capital and IAPAM; however, IAPAM does not provide any soft dollar research benefit to the Funds and/or other accounts managed by Invesco Aim or Invesco Aim Capital.

Invesco Aim and Invesco Aim Capital attempt to reduce or eliminate the potential conflicts of interest concerning the use of Soft Dollar Products by directing client trades for Soft Dollar Products only if Invesco Aim and Invesco Aim Capital conclude that the Broker supplying the product is capable of providing best execution.

Certain Soft Dollar Products may be available directly from a vendor on a hard dollar basis; other Soft Dollar Products are available only through Brokers in exchange for soft dollars. Invesco Aim uses soft dollars to purchase two types of Soft Dollar Products:

- proprietary research created by the Broker executing the trade, and

- other products created by third parties that are supplied to Invesco Aim through the Broker executing the trade.

Proprietary research consists primarily of traditional research reports, recommendations and similar materials produced by the in house research staffs of broker-dealer firms. This research includes evaluations and recommendations of specific companies or industry groups, as well as analyses of general economic and market conditions and trends, market data, contacts and other related information and assistance. Invesco Aim periodically rates the quality of proprietary research produced by various Brokers. Based on the evaluation of the quality of information that Invesco Aim receives from each Broker, Invesco Aim develops an estimate of each Broker's share of Invesco Aim clients' commission dollars. Invesco Aim attempts to direct trades to the firms to meet these estimates.

43

Invesco Aim also uses soft dollars to acquire products from third parties that are supplied to Invesco Aim through Brokers executing the trades or other Brokers who "step in" to a transaction and receive a portion of the brokerage commission for the trade. Invesco Aim may from time to time instruct the executing Broker to allocate or "step out" a portion of a transaction to another Broker. The Broker to which Invesco Aim has "stepped out" would then settle and complete the designated portion of the transaction, and the executing Broker would settle and complete the remaining portion of the transaction that has not been "stepped out." Each Broker may receive a commission or brokerage fee with respect to that portion of the transaction that it settles and completes.

Soft Dollar Products received from Brokers supplement Invesco Aim's own research (and the research of certain of its affiliates), and may include the following types of products and services:

- Database Services - comprehensive databases containing current and/or historical information on companies and industries and indices. Examples include historical securities prices, earnings estimates and financial data. These services may include software tools that allow the user to search the database or to prepare value-added analyses related to the investment process (such as forecasts and models used in the portfolio management process).

- Quotation/Trading/News Systems - products that provide real time market data information, such as pricing of individual securities and information on current trading, as well as a variety of news services.

- Economic Data/Forecasting Tools - various macro economic forecasting tools, such as economic data or currency and political forecasts for various countries or regions.

- Quantitative/Technical Analysis - software tools that assist in quantitative and technical analysis of investment data.

- Fundamental/Industry Analysis - industry specific fundamental investment research.

- Fixed Income Security Analysis - data and analytical tools that pertain specifically to fixed income securities. These tools assist in creating financial models, such as cash flow projections and interest rate sensitivity analyses, which are relevant to fixed income securities.

- Other Specialized Tools - other specialized products, such as consulting analyses, access to industry experts, and distinct investment expertise such as forensic accounting or custom built investment-analysis software.

If Invesco Aim determines that any service or product has a mixed use (i.e., it also serves functions that do not assist the investment decision-making or trading process), Invesco Aim will allocate the costs of such service or product accordingly in its reasonable discretion. Invesco Aim will allocate brokerage commissions to Brokers only for the portion of the service or product that Invesco Aim determines assists it in the investment decision-making or trading process and will pay for the remaining value of the product or service in cash.

Outside research assistance is useful to Invesco Aim since the Brokers used by Invesco Aim tend to provide more in-depth analysis of a broader universe of securities and other matters than Invesco Aim's staff follows. In addition, such services provide Invesco Aim with a diverse perspective on financial markets. Some brokers may indicate that the provision of research services is dependent upon the generation of certain specified levels of commissions and underwriting concessions by Invesco Aim's clients, including the Funds. However, the Funds are not under any obligation to deal with any Broker in the execution of transactions in portfolio securities. In some cases, Soft Dollar Products are available

44

only from the Broker providing them. In other cases, Soft Dollar Products may be obtainable from alternative sources in return for cash payments. Invesco Aim's believes that because Broker research supplements rather than replaces Invesco Aim's research, the receipt of such research tends to improve the quality of Invesco Aim's investment advice. The advisory fee paid by the Funds is not reduced because Invesco Aim receives such services. To the extent the Funds' portfolio transactions are used to obtain Soft Dollar Products, the brokerage commissions obtained by the Funds might exceed those that might otherwise have been paid.

Invesco Aim may determine target levels of brokerage business with various Brokers on behalf of its clients (including the Funds) over a certain time period. The target levels will be based upon the following factors, among others: (1) the execution services provided by the Broker; and (2) the research services provided by the Broker. Portfolio transactions may be effected through Brokers that recommend the Funds to their clients, or that act as agent in the purchase of a Fund's shares for their clients, provided that Invesco Aim believes such Brokers provide best execution and such transactions are executed in compliance with Invesco Aim's policy against using directed brokerage to compensate Brokers for promoting or selling AIM Fund shares. Invesco Aim will not enter into a binding commitment with Brokers to place trades with such Brokers involving brokerage commissions in precise amounts.

DIRECTED BROKERAGE (RESEARCH SERVICES)

Directed brokerage (research services) paid by each of the Funds during the last fiscal year ended March 31, 2008 are found in Appendix K.

REGULAR BROKERS

Information concerning the Funds' acquisition of securities of their regular Brokers or dealers during the last fiscal year ended March 31, 2008 is found in Appendix K.

ALLOCATION OF PORTFOLIO TRANSACTIONS

Invesco Aim and its affiliates manage numerous AIM Funds and other accounts. Some of these accounts may have investment objectives similar to the Funds. Occasionally, identical securities will be appropriate for investment by one of the Funds and by another Fund or one or more other accounts. However, the position of each account in the same security and the length of time that each account may hold its investment in the same security may vary. The timing and amount of purchase by each account will also be determined by its cash position. If the purchase or sale of securities is consistent with the investment policies of the Fund(s) and one or more other accounts, and is considered at or about the same time, Invesco Aim will allocate transactions in such securities among the Fund(s) and these accounts on a pro rata basis based on order size or in such other manner believed by Invesco Aim to be fair and equitable. Invesco Aim may combine such transactions, in accordance with applicable laws and regulations, to obtain the most favorable execution. Simultaneous transactions could, however, adversely affect a Fund's ability to obtain or dispose of the full amount of a security which it seeks to purchase or sell.

45

PURCHASE, REDEMPTION AND PRICING OF SHARES

TRANSACTIONS THROUGH FINANCIAL INTERMEDIARIES

If you are investing indirectly in a Fund through a financial intermediary such as a broker-dealer, a bank (including a bank trust department), an insurance company separate account, an investment advisor, an administrator or trustee of a retirement plan or a qualified tuition plan or a sponsor of a fee-based program that maintains a master account (an omnibus account) with the Fund for trading on behalf of its customers, different guidelines, conditions and restrictions may apply than if you held your shares of the Fund directly. These differences may include, but are not limited to: (i) different eligibility standards to purchase and sell shares, different eligibility standards to invest in funds with limited offering status and different eligibility standards to exchange shares by telephone; (ii) different minimum and maximum initial and subsequent purchase amounts; (iii) system inability to provide Letter of Intent privileges; and (iv) different annual amounts (less than 12%) subject to withdrawal under a Systematic Redemption Plan without being subject to a contingent deferred sales charge. The financial intermediary through whom you are investing may also choose to adopt different exchange and/or transfer limit guidelines and restrictions, including different trading restrictions designed to discourage excessive or short-term trading. The financial intermediary through whom you are investing may also choose to impose a redemption fee that has different characteristics, which may be more or less restrictive, than the redemption fee currently imposed on certain Funds.

If the financial intermediary is managing your account, you may also be charged a transaction or other fee by such financial intermediary, including service fees for handling redemption transactions. Consult with your financial intermediary (or, in the case of a retirement plan, your plan sponsor) to determine what fees, guidelines, conditions and restrictions, including any of the above, may be applicable to you.

PURCHASE AND REDEMPTION OF SHARES

Purchases of Class A Shares, Class A3 Shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund and AIM Cash Reserve Shares of AIM Money Market Fund

INITIAL SALES CHARGES. Each AIM Fund (other than AIM Tax-Exempt Cash Fund) is grouped into one of four categories to determine the applicable initial sales charge for its Class A shares. The sales charge is used to compensate Invesco Aim Distributors and participating dealers for their expenses incurred in connection with the distribution of the Funds' shares. You may also be charged a transaction or other fee by the financial institution managing your account.

Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund and AIM Cash Reserve Shares of AIM Money Market Fund are sold without an initial sales charge.

LARGE PURCHASES OF CLASS A SHARES. Investors who purchase $1,000,000 or more of Class A shares of Category I, II, III or IV Funds do not pay an initial sales charge. In addition, investors who currently own Class A shares of Category I, II, III or IV Funds and make additional purchases that result in account balances of $1,000,000 or more do not pay an initial sales charge on the additional purchases. The additional purchases, as well as initial purchases of $1,000,000 or more, are referred to as Large Purchases. If an investor makes a Large Purchase of Class A shares of a Category I, II or IV Funds, each share will generally be subject to a 1.00% contingent deferred sales charge ("CDSC") if the investor redeems those shares within 18 months after purchase.

Invesco Aim Distributors may pay a dealer concession and/or advance a service fee on Large Purchases, as set forth below. Exchanges between the AIM Funds may affect total compensation paid.

PURCHASES OF CLASS A SHARES BY NON-RETIREMENT PLANS. Invesco Aim Distributors may make the following payments to dealers of record for Large Purchases of Class A shares of Category I, II or IV Funds by investors other than: (i) retirement plans that are maintained pursuant to Sections 401 and 457 of the Internal Revenue Code of 1986, as amended (the "Code"), and (ii) retirement plans that are maintained pursuant to Section 403 of the Code if the employer or plan sponsor is a tax-exempt organization operated pursuant to
Section 501(c)(3) of the Code:

PERCENT OF PURCHASES

1% of the first $2 million
plus 0.80% of the next $1 million
plus 0.50% of the next $17 million
plus 0.25% of amounts in excess of $20 million

If (i) the amount of any single purchase order plus (ii) the public offering price of all other shares owned by the same customer submitting the purchase order on the day on which the purchase order is received equals or exceeds $1,000,000, the purchase will be considered a "jumbo accumulation purchase." With regard to any individual jumbo accumulation purchase, Invesco Aim Distributors may make payment to the dealer of record based on the cumulative total of jumbo accumulation purchases made by the same customer over the life of his or her account(s).

If an investor makes a Large Purchase of Class A3 shares of a Category III Fund on and after October 31, 2002 and exchanges those shares for Class A shares of a Category I, II or IV Fund, Invesco Aim Distributors will pay 1.00% of such purchase as dealer compensation upon the exchange. The Class A shares of the Category I, II or IV Fund received in exchange generally will be subject to a 1.00% CDSC if the investor redeems such shares within 18 months from the date of exchange.

PURCHASES OF CLASS A SHARES BY CERTAIN RETIREMENT PLANS AT NAV. For purchases of Class A shares of Category I, II and IV Funds, Invesco Aim Distributors may make the following payments to investment dealers or other financial service firms for sales of such shares at net asset value ("NAV") to certain retirement plans provided that the applicable dealer of record is able to establish that the retirement plan's purchase of such Class A shares is a new investment (as defined below):

49

PERCENT OF PURCHASES

0.50% of the first $20 million
plus 0.25% of amounts in excess of $20 million

This payment schedule will be applicable to purchases of Class A shares at NAV by the following types of retirement plans: (i) all plans maintained pursuant to Sections 401 and 457 of the Code, and (ii) plans maintained pursuant to Section 403 of the Code if the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code.

A "new investment" means a purchase paid for with money that does not represent (i) the proceeds of one or more redemptions of AIM Fund shares, (ii) an exchange of AIM Fund shares, (iii) the repayment of one or more retirement plan loans that were funded through the redemption of AIM Fund shares, or (iv) money returned from another fund family. If Invesco Aim Distributors pays a dealer concession in connection with a plan's purchase of Class A shares at NAV, such shares may be subject to a CDSC of 1.00% of net assets for 12 months, commencing on the date the plan first invests in Class A shares of an AIM Fund. If the applicable dealer of record is unable to establish that a plan's purchase of Class A shares at NAV is a new investment, Invesco Aim Distributors will not pay a dealer concession in connection with such purchase and such shares will not be subject to a CDSC.

With regard to any individual jumbo accumulation purchase, Invesco Aim Distributors may make payment to the dealer of record based on the cumulative total of jumbo accumulation purchases made by the same plan over the life of the plan's account(s).

HOW TO QUALIFY FOR REDUCTIONS IN INITIAL SALES CHARGES. The following sections discuss different ways that a Qualified Purchaser can qualify for a reduction in the initial sales charges for purchases of Class A shares of the AIM Funds.

LETTERS OF INTENT

A Qualified Purchaser may pay reduced initial sales charges by (i) indicating on the Account Application that he, she or it intends to provide a Letter of Intent ("LOI"); and (ii) subsequently fulfilling the conditions of that LOI. Employer-sponsored retirement plans, with the exception of Solo 401(k) plans and SEP plans, are not eligible for a LOI.

The LOI confirms the total investment in shares of the AIM Funds that the Qualified Purchaser intends to make within the next 13 months. By marking the LOI section on the account application and by signing the account application, the Qualified Purchaser indicates that he, she or it understands and agrees to the terms of the LOI and is bound by the provisions described below:

Calculating the Initial Sales Charge

- Each purchase of fund shares normally subject to an initial sales charge made during the 13-month period will be made at the public offering price applicable to a single transaction of

51

the total dollar amount indicated by the LOI (to determine what the applicable public offering price is, look at the sales charge table in the section on "Initial Sales Charges" above).

- It is the purchaser's responsibility at the time of purchase to specify the account numbers that should be considered in determining the appropriate sales charge.

- The offering price may be further reduced as described below under "Rights of Accumulation" if Invesco Aim Investment Services, the Funds' transfer agent ("Transfer Agent") is advised of all other accounts at the time of the investment.

- Reinvestment of dividends and capital gains distributions acquired during the 13-month LOI period will not be applied to the LOI.

Calculating the Number of Shares to be Purchased

- Purchases made and shares acquired through reinvestment of dividends and capital gains distributions prior to the LOI effective date will be applied toward the completion of the LOI based on the value of the shares calculated at the public offering price on the effective date of the LOI.

- If a purchaser wishes to revise the LOI investment amount upward, he, she or it may submit a written and signed request at anytime prior to the completion of the original LOI. This revision will not change the original expiration date.

- The Transfer Agent will process necessary adjustments upon the expiration or completion date of the LOI.

Fulfilling the Intended Investment

- By signing an LOI, a purchaser is not making a binding commitment to purchase additional shares, but if purchases made within the 13-month period do not total the amount specified, the purchaser will have to pay the increased amount of sales charge.

- To assure compliance with the provisions of the 1940 Act, the Transfer Agent will escrow in the form of shares an appropriate dollar amount (computed to the nearest full share) out of the initial purchase (or subsequent purchases if necessary). All dividends and any capital gain distributions on the escrowed shares will be credited to the purchaser. All shares purchased, including those escrowed, will be registered in the purchaser's name. If the total investment specified under this LOI is completed within the 13-month period, the escrowed shares will be promptly released.

- If the intended investment is not completed, the purchaser will pay the Transfer Agent the difference between the sales charge on the specified amount and the sales charge on the amount actually purchased. If the purchaser does not pay such difference within 20 days of the expiration date, he or she irrevocably constitutes and appoints the Transfer Agent as his attorney to surrender for redemption any or all shares, to make up such difference within 60 days of the expiration date.

Canceling the LOI

- If at any time before completing the LOI Program, the purchaser wishes to cancel the agreement, he or she must give written notice to Invesco Aim Distributors or its designee.

52

- If at any time before completing the LOI Program the purchaser requests the Transfer Agent to liquidate or transfer beneficial ownership of his total shares, the LOI will be automatically canceled. If the total amount purchased is less than the amount specified in the LOI, the Transfer Agent will redeem an appropriate number of escrowed shares equal to the difference between the sales charge actually paid and the sales charge that would have been paid if the total purchases had been made at a single time.

Other Persons Eligible for the LOI Privilege

The LOI privilege is also available to holders of the Connecticut General Guaranteed Account, established for tax qualified group annuities, for contracts purchased on or before June 30, 1992.

LOIs and Contingent Deferred Sales Charges

All LOIs to purchase $1,000,000 or more of Class A shares of Category I, II and IV Funds are subject to an 18-month, 1% CDSC.

RIGHTS OF ACCUMULATION

A Qualified Purchaser may also qualify for reduced initial sales charges based upon his, her or its existing investment in shares of any of the AIM Funds at the time of the proposed purchase. To determine whether or not a reduced initial sales charge applies to a proposed purchase, Invesco Aim Distributors takes into account not only the money which is invested upon such proposed purchase, but also the value of all shares of the AIM Funds owned by such purchaser, calculated at their then current public offering price.

If a purchaser qualifies for a reduced sales charge, the reduced sales charge applies to the total amount of money being invested, even if only a portion of that amount exceeds the breakpoint for the reduced sales charge. For example, if a purchaser already owns qualifying shares of any AIM Fund with a value of $20,000 and wishes to invest an additional $20,000 in a fund with a maximum initial sales charge of 5.50%, the reduced initial sales charge of 5.25% will apply to the full $20,000 purchase and not just to the $15,000 in excess of the $25,000 breakpoint.

To qualify for obtaining the discount applicable to a particular purchase, the purchaser or his dealer must furnish the Transfer Agent with a list of the account numbers and the names in which such accounts of the purchaser are registered at the time the purchase is made.

Rights of Accumulation are also available to holders of the Connecticut General Guaranteed Account, established for tax-qualified group annuities, for contracts purchased on or before June 30, 1992.

If an investor's new purchase of Class A shares of a Category I, II or IV Fund is at net asset value, the newly purchased shares will be subject to a CDSC if the investor redeems them prior to the end of the 18 month holding period.

REINSTATEMENT FOLLOWING REDEMPTION

If you redeem shares of a fund, you may reinvest all or a portion of the proceeds from the redemption in the same share class of any fund in the same Category within 180 days of the redemption without paying an initial sales charge. Class B and P redemptions may be reinvested in Class A shares with no initial sales charge. This reinstatement privilege does not apply to:

- A purchase made through a regularly scheduled automatic investment plan, such as a purchase by a regularly scheduled payroll deduction or transfer from a bank account, or

53

- A purchase paid for with proceeds from the redemption of shares that were held indirectly through an employee benefit plan.

In order to take advantage of this reinstatement privilege, you must inform your financial advisor or the transfer agent that you wish to do so at the time of your investment.

OTHER REQUIREMENTS FOR REDUCTIONS IN INITIAL SALES CHARGES. As discussed above, investors or dealers seeking to qualify orders for a reduced initial sales charge must identify such orders and, if necessary, support their qualification for the reduced charge. Invesco Aim Distributors reserves the right to determine whether any purchaser is entitled to the reduced sales charge based on the definition of a Qualified Purchaser listed above. No person or entity may distribute shares of the AIM Funds without payment of the applicable sales charge other than to Qualified Purchasers.

Purchases of Class A shares of AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund, AIM Cash Reserve Shares of AIM Money Market Fund and Investor Class shares of any Fund will not be taken into account in determining whether a purchase qualifies for a reduction in initial sales charges.

PURCHASES OF CLASS A SHARES AT NET ASSET VALUE. Invesco Aim Distributors permits certain categories of persons to purchase Class A shares of AIM Funds without paying an initial sales charge. These are typically categories of persons whose transactions involve little expense, such as persons who have a relationship with the funds or with Invesco Aim and certain programs for purchase. It is the purchaser's responsibility to notify Invesco Aim Distributors or its designee of any qualifying relationship at the time of purchase.

Invesco Aim Distributors believes that it is appropriate and in the Funds' best interests that such persons, and certain other persons whose purchases result in relatively low expenses of distribution, be permitted to purchase shares through Invesco Aim Distributors without payment of a sales charge.

Accordingly, the following purchasers will not pay initial sales charges on purchases of Class A shares because there is a reduced sales effort involved in sales to these purchasers:

- Any current or retired trustee, director, officer or employee of any AIM Fund or of Invesco Ltd. or any of its subsidiaries or affiliates, or any foundation, trust or employee benefit plan maintained by any of them (this includes any members of their Immediate Family);

- Any current or retired officer, director, or employee (and members of their Immediate Family) of DST Systems, Inc. or Personix, a division of Fiserv Solutions, Inc.;

- Any registered representative or employee of any intermediary who has an agreement with Invesco Aim Distributors to sell shares of the Funds (this includes any members of their Immediate Family);

- Any investor who purchases their shares through an approved fee-based program (this may include any type of account for which there is some alternative arrangement made between the investor and the intermediary to provide for compensation of the intermediary for services rendered in connection with the sale of the shares and maintenance of the customer relationship);

- Any investor who purchases their shares with the proceeds of a rollover, transfer or distribution from a retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor to another retirement plan or individual retirement account for which Invesco Aim Distributors acts as the prototype sponsor, to the extent that such proceeds are attributable to the redemption of shares of a fund held through the plan or account;

54

- Employer-sponsored retirement plans that are Qualified Purchasers, as defined above, provided that:

a. the plan has assets of at least $1 million;

b. there are at least 100 employees eligible to participate in the plan; or

c. all plan transactions are executed through a single omnibus account per Fund; further provided that retirement plans maintained pursuant to Section 403(b) of the Code are not eligible to purchase shares without paying an initial sales charge based on the aggregate investment made by the plan or the number of eligible employees unless the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code;

- "Grandfathered" shareholders as follows:

a. Shareholders of record of Advisor Class shares of AIM International Growth Fund or AIM Worldwide Growth Fund on February 12, 1999 who have continuously owned shares of the AIM Funds;

b. Shareholders of record or discretionary advised clients of any investment advisor holding shares of AIM Weingarten Fund or AIM Constellation Fund on September 8, 1986, or of AIM Charter Fund on November 17, 1986, who have continuously owned shares and who purchase additional shares of AIM Constellation Fund or AIM Charter Fund, respectively;

c. Unitholders of G/SET series unit investment trusts investing proceeds from such trusts in shares of AIM Constellation Fund; provided, however, prior to the termination date of the trusts, a unitholder may invest proceeds from the redemption or repurchase of his units only when the investment in shares of AIM Constellation Fund is effected within 30 days of the redemption or repurchase;

d. A shareholder of a fund that merges or consolidates with an AIM Fund or that sells its assets to an AIM Fund in exchange for shares of an AIM Fund;

e. Shareholders of the former GT Global funds as of April 30, 1987 who since that date continually have owned shares of one or more of these funds;

f. Certain former AMA Investment Advisers' shareholders who became shareholders of the AIM Global Health Care Fund in October 1989, and who have continuously held shares in the GT Global funds since that time;

g. Shareholders of record of Advisor Class shares of an AIM Fund on February 11, 2000 who have continuously owned shares of that AIM Fund, and who purchase additional shares of that AIM Fund; and

h. Additional purchases of Class A shares by shareholders of record of Class K shares on October 21, 2005 whose Class K shares were converted to Class A shares.

- Any investor who maintains an account in Investor Class shares of a Fund (this includes anyone listed in the registration of an account, such as a joint owner, trustee or custodian, and members of their Immediate Family);

- Qualified Tuition Programs created and maintained in accordance with
Section 529 of the Code;

55

- Insurance company separate accounts;

- Retirement plan established exclusively for the benefit of an individual (specifically including, but not limited to, a Traditional IRA, Roth IRA, SEP IRA, SIMPLE IRA, Solo 401(k), Keogh plan, or a tax-sheltered 403(b)(7) custodial account) if:

a. such plan is funded by a rollover of assets from an Employer-Sponsored Retirement Plan;

b. the account being funded by such rollover is to be maintained by the same trustee, custodian or administrator that maintained the plan from which the rollover distribution funding such rollover originated, or an affiliate thereof; and

c. the dealer of record with respect to the account being funded by such rollover is the same as the dealer of record with respect to the plan from which the rollover distribution funding such rollover originated, or an affiliate thereof.

- Transfers to IRAs that are attributable to AIM Fund investments held in 403(b)(7)s, SIMPLEs, SEPs, SARSEPs, Traditional or Roth IRAs; and

- Rollovers from Invesco Aim held 403(b)(7)s, 401(K)s, SEPs, SIMPLEs, SARSEPs, Money Purchase Plans, and Profit Sharing Plans if the assets are transferred to an Invesco Aim IRA.

In addition, an investor may acquire shares of any of the AIM Funds at net asset value in connection with:

- when reinvesting dividends and distributions;

- when exchanging shares of one Fund, that were previously assessed a sales charge, for shares of another Fund; as more fully described in the Prospectus;

- the purchase of shares in connection with the repayment of a retirement plan loan administered by Invesco Aim Investment Services;

- as a result of a Fund's merger, consolidation or acquisition of the assets of another Fund;

- the purchase of Class A shares with proceeds from the redemption of Class B or Class C shares where the redemption and purchase are effectuated on the same business day; or

- when buying Class A shares of AIM Tax-Exempt Cash Fund.

PAYMENTS TO DEALERS. Invesco Aim Distributors may elect to re-allow the entire initial sales charge to dealers for all sales with respect to which orders are placed with Invesco Aim Distributors during a particular period. Dealers to whom substantially the entire sales charge is re-allowed may be deemed to be "underwriters" as that term is defined under the 1933 Act.

The financial advisor through which you purchase your shares may receive all or a portion of the sales charges and Rule 12b-1 distribution fees discussed above. In this context, "financial advisors" include any broker, dealer, bank (including bank trust departments), insurance company separate account, transfer agent, registered investment advisor, financial planner, retirement plan administrator and any other financial intermediary having a selling, administration or similar agreement with Invesco Aim Distributors or one or more of its corporate affiliates (collectively, the "Invesco Aim Distributors Affiliates"). In addition to those payments, Invesco Aim Distributors Affiliates may make additional cash payments to financial advisors in connection with the promotion and sale of shares of AIM Funds. Invesco Aim Distributors Affiliates make these payments from their own resources, from Invesco Aim Distributors' retention of underwriting concessions and from payments to Invesco Aim Distributors under

56

Rule 12b-1 plans. In the case of sub-accounting payments, discussed below, Invesco Aim Distributors Affiliates will be reimbursed directly by the AIM Funds for such payments. These additional cash payments are described below. The categories described below are not mutually exclusive. The same financial advisor, or one or more of its affiliates, may receive payments under more than one or all categories. Most financial advisors that sell shares of AIM Funds receive one or more types of these cash payments. Financial advisors negotiate the cash payments to be paid on an individual basis. Where services are provided, the costs of providing the services and the overall package of services provided may vary from one financial advisor to another. Invesco Aim Distributors Affiliates do not make an independent assessment of the cost of providing such services.

A list of certain financial advisors that received one or more types of payments below during the prior calendar year is attached here as Appendix L. This list is not necessarily current and will change over time. Certain arrangements are still being negotiated, and there is a possibility that payments will be made retroactively to financial advisors not listed below. Accordingly, please contact your financial advisor to determine whether they currently may be receiving such payments and to obtain further information regarding any such payments.

FINANCIAL SUPPORT PAYMENTS. Invesco Aim Distributors Affiliates make financial support payments as incentives to certain financial advisors to promote and sell shares of AIM Funds. The benefits Invesco Aim Distributors Affiliates receive when they make these payments include, among other things, placing AIM Funds on the financial advisor's funds sales system, and access (in some cases on a preferential basis over other competitors) to individual members of the financial advisor's sales force or to the financial advisor's management. Financial support payments are sometimes referred to as "shelf space" payments because the payments compensate the financial advisor for including AIM Funds in its fund sales system (on its "sales shelf"). Invesco Aim Distributors Affiliates compensate financial advisors differently depending typically on the level and/or type of considerations provided by the financial advisor. In addition, payments typically apply only to retail sales, and may not apply to other types of sales or assets (such as sales to retirement plans, qualified tuition programs, or fee based advisor programs - some of which may generate certain other payments described below).

The financial support payments Invesco Aim Distributors Affiliates make may be calculated on sales of shares of AIM Funds ("Sales-Based Payments"), in which case the total amount of such payments shall not exceed 0.25% (for non-Institutional Class shares) or 0.10% (for Institutional Class shares) of the public offering price of all such shares sold by the financial advisor during the particular period. Such payments also may be calculated on the average daily net assets of the applicable AIM Funds attributable to that particular financial advisor ("Asset-Based Payments"), in which case the total amount of such cash payments shall not exceed 0.25% per annum of those assets during a defined period. Sales-Based Payments primarily create incentives to make new sales of shares of AIM Funds and Asset-Based Payments primarily create incentives to retain previously sold shares of AIM Funds in investor accounts. Invesco Aim Distributors Affiliates may pay a financial advisor either or both Sales-Based Payments and Asset-Based Payments.

SUB-ACCOUNTING AND NETWORKING SUPPORT PAYMENTS. Invesco Aim Investment Services, an Invesco Aim Distributors Affiliate, acts as the transfer agent for the AIM Funds, registering the transfer, issuance and redemption of AIM Fund shares, and disbursing dividends and other distributions to AIM Funds shareholders. However, many AIM Fund shares are owned or held by financial advisors, as that term is defined above, for the benefit of their customers. In those cases, the AIM Funds often do not maintain an account for the shareholder. Thus, some or all of the transfer agency functions for these accounts are performed by the financial advisor. In these situations, Invesco Aim Distributors Affiliates may make payments to financial advisors that sell AIM Fund shares for certain transfer agency services, including record keeping and sub-accounting shareholder accounts. Payments for these services typically do not exceed 0.25% (for non-Institutional Class shares) or 0.10% (for Institutional Class shares) of average annual assets of such share classes or $19 per annum per shareholder account (for non-Institutional Class shares only). Invesco Aim Distributors Affiliates also may make payments to certain financial advisors that sell AIM Fund shares in connection with client account maintenance support, statement preparation and transaction processing. The types of payments that Invesco Aim Distributors

57

Affiliates may make under this category include, among others, payment of networking fees of up to $12 per shareholder account maintained on certain mutual fund trading systems.

All fees payable by Invesco Aim Distributors Affiliates pursuant to a sub-transfer agency, omnibus account service or sub-accounting agreement are charged back to the AIM Funds, subject to certain limitations approved by the Board of the Trust.

OTHER CASH PAYMENTS. From time to time, Invesco Aim Distributors Affiliates, at their expense and out of their own resources, may provide additional compensation to financial advisors which sell or arrange for the sale of shares of the Fund. Such compensation provided by Invesco Aim Distributors Affiliates may include payment of ticket charges per purchase or exchange order placed by a financial advisor, one-time payments for ancillary services such as setting up funds on a financial advisor's mutual fund trading systems, financial assistance to financial advisors that enable Invesco Aim Distributors Affiliates to participate in and/or present at conferences or seminars, sales or training programs for invited registered representatives and other employees, client entertainment, client and investor events, and other financial advisor-sponsored events, and travel expenses, including lodging incurred by registered representatives and other employees in connection with client prospecting, retention and due diligence trips. Other compensation may be offered to the extent not prohibited by state laws or any self-regulatory agency, such as the Financial Industry Regulatory Authority ("FINRA") (formerly, NASD, Inc.). Invesco Aim Distributors Affiliates make payments for entertainment events it deems appropriate, subject to Invesco Aim Distributors Affiliates guidelines and applicable law. These payments may vary depending upon the nature of the event or the relationship.

Invesco Aim Distributors Affiliates are motivated to make the payments described above since they promote the sale of AIM Fund shares and the retention of those investments by clients of financial advisors. To the extent financial advisors sell more shares of AIM Funds or retain shares of AIM Funds in their clients' accounts, Invesco Aim Distributors Affiliates benefit from the incremental management and other fees paid to Invesco Aim Distributors Affiliates by the AIM Funds with respect to those assets.

In certain cases these payments could be significant to the financial advisor. Your financial advisor may charge you additional fees or commissions other than those disclosed in the prospectus. You can ask your financial advisor about any payments it receives from Invesco Aim Distributors Affiliates or the AIM Funds, as well as about fees and/or commissions it charges. You should consult disclosures made by your financial advisor at the time of purchase.

Purchases of Class B Shares

Class B shares are sold at net asset value, and are not subject to an initial sales charge. Instead, investors may pay a CDSC if they redeem their shares within six years after purchase. See the Prospectus for additional information regarding contingent deferred sales charges. Invesco Aim Distributors may pay sales commissions to dealers and institutions who sell Class B shares of the AIM Funds at the time of such sales. Payments will equal 4.00% of the purchase price and will consist of a sales commission equal to 3.75% plus an advance of the first year service fee of 0.25%.

Purchases of Class C Shares

Class C shares are sold at net asset value, and are not subject to an initial sales charge. Instead, investors may pay a CDSC if they redeem their shares within the first year after purchase (no CDSC applies to Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund unless you exchange shares of another AIM Fund that are subject to a CDSC into AIM LIBOR Alpha Fund or AIM Short Term Bond Fund). See the Prospectus for additional information regarding this CDSC. Invesco Aim Distributors may pay sales commissions to dealers and institutions who sell Class C shares of the AIM Funds (except for Class C shares of AIM LIBOR Alpha Fund and AIM Short Term Bond Fund) at the time of such sales. Payments with respect to Funds other than AIM Floating Rate Fund will equal 1.00% of the purchase price and will consist of a sales commission of 0.75% plus an advance of the first year service fee of 0.25%. Payments with respect to AIM Floating Rate Fund will equal 0.75% of the purchase

58

price and will consist of a sales commission of 0.50% plus an advance of the first year service fee of 0.25%. These commissions are not paid on sales to investors exempt from the CDSC, including shareholders of record of AIM Advisor Funds, Inc. on April 30, 1995, who purchase additional shares in any of the Funds on or after May 1, 1995, and in circumstances where Invesco Aim Distributors grants an exemption on particular transactions.

Payments with Regard to Converted Class K Shares

For Class A shares acquired by a former Class K shareholder (i) as a result of a fund merger; or (ii) as a result of the conversion of Class K shares into Class A shares on October 21, 2005, Invesco Aim Distributors will pay financial intermediaries 0.45% on such Class A shares as follows: (i) 0.25% from the Class A shares' Rule 12b-1 plan fees; and (ii) 0.20% from Invesco Aim Distributors' own resources provided that, on an annualized basis for 2005 as of October 21, 2005, the 0.20% exceeds $2,000 per year.

Purchase and Redemption of Class P Shares

Certain former investors in the AIM Summit Plans I and II may acquire Class P shares at net asset value. Please see AIM Summit Fund's Prospectus for details.

Purchases of Class R Shares

Class R shares are sold at net asset value, and are not subject to an initial sales charge. If Invesco Aim Distributors pays a concession to the dealer of record, however, the Class R shares are subject to a 0.75% CDSC at the time of redemption if all retirement plan assets are redeemed within one year from the date of the retirement plan's initial purchase. For purchases of Class R shares of Category I, II or IV Funds, Invesco Aim Distributors may make the following payments to dealers of record provided that the applicable dealer of record is able to establish that the purchase of Class R shares is a new investment or a rollover from a retirement plan in which an AIM Fund was offered as an investment option:

PERCENT OF CUMULATIVE PURCHASES

0.75% of the first $5 million

plus 0.50% of amounts in excess of $5 million

With regard to any individual purchase of Class R shares, Invesco Aim Distributors may make payment to the dealer of record based on the cumulative total of purchases made by the same plan over the life of the plan's account(s).

Purchases of Investor Class Shares

Investor Class shares are sold at net asset value, and are not subject to an initial sales charge or to a CDSC. Invesco Aim Distributors may pay dealers and institutions an annual service fee of 0.25% of average daily net assets and such payments will commence immediately. The Investor Class is closed to new investors.

Purchases of Institutional Class Shares

Institutional Class shares are sold at net asset value, and are not subject to an initial sales charge or to a CDSC. Please refer to the Institutional Class Prospectus for more information.

Exchanges

TERMS AND CONDITIONS OF EXCHANGES. Normally, shares of an AIM Fund to be acquired by exchange are purchased at their net asset value or applicable offering price, as the case may be, determined on the date that such request is received, but under unusual market conditions such purchases may be delayed for up to five business days if it is determined that a fund would be materially disadvantaged by an immediate transfer of the proceeds of the exchange. If a shareholder is exchanging into a fund paying daily dividends, and the release of the exchange proceeds is delayed for the foregoing five-day period, such shareholder will not begin to accrue dividends until the sixth business day after the exchange.

Redemptions

GENERAL. Shares of the AIM Funds may be redeemed directly through Invesco Aim Distributors or through any dealer who has entered into an agreement with Invesco Aim Distributors. In addition to the Funds' obligation to redeem shares, Invesco Aim Distributors may also repurchase shares as an accommodation to shareholders. To effect a repurchase, those dealers who have executed Selected Dealer Agreements with Invesco Aim Distributors must phone orders to the order desk of the Funds at (800) 959-4246 and guarantee delivery of all required documents in good order. A repurchase is effected at the net asset value per share of the applicable Fund next determined after the repurchase order is received in good order. Such an arrangement is subject to timely receipt by Invesco Aim Investment Services, the Funds' transfer agent, of all required documents in good order. If such documents are not received within a reasonable time after the order is placed, the order is subject to cancellation. While there is no charge imposed by a Fund or by Invesco Aim Distributors (other than any applicable contingent deferred sales charge and any applicable redemption fee) when shares are redeemed or repurchased, dealers may charge a fair service fee for handling the transaction.

SUSPENSION OF REDEMPTIONS. The right of redemption may be suspended or the date of payment postponed when (a) trading on the New York Stock Exchange ("NYSE") is restricted, as determined by applicable rules and regulations of the SEC, (b) the NYSE is closed for other than customary weekend and holiday closings, (c) the SEC has by order permitted such suspension, or (d) an emergency as determined by the SEC exists making disposition of portfolio securities or the valuation of the net assets of a Fund not reasonably practicable.

SYSTEMATIC REDEMPTION PLAN. A Systematic Redemption Plan permits a shareholder of an AIM Fund to withdraw on a regular basis at least $50 per withdrawal. At the time the withdrawal plan is established, the total account value must be $5,000 or more. Under a Systematic Redemption Plan, all shares are to be held by Invesco Aim Investment Services. To provide funds for payments made under the Systematic Redemption Plan, Invesco Aim Investment Services redeems sufficient full and fractional shares at their net asset value in effect at the time of each such redemption.

Payments under a Systematic Redemption Plan constitute taxable events. Since such payments are funded by the redemption of shares, they may result in a return of capital and in capital gains or losses, rather than in ordinary income. Because sales charges are imposed on additional purchases of Class A shares, it is disadvantageous to effect such purchases while a Systematic Redemption Plan is in effect.

Each AIM Fund bears its share of the cost of operating the Systematic Redemption Plan.

Contingent Deferred Sales Charges Imposed upon Redemption of Shares

A CDSC may be imposed upon the redemption of Large Purchases of Class A shares of Category I, II and IV Funds, upon the redemption of Class B shares or Class C shares (no CDSC applies to Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund unless you exchange shares of another AIM Fund that are subject to a CDSC into AIM LIBOR Alpha Fund or AIM Short Term Bond

60

Fund) and, in certain circumstances, upon the redemption of Class R shares. See the Prospectus for additional information regarding CDSCs.

CONTINGENT DEFERRED SALES CHARGE EXCEPTIONS FOR LARGE PURCHASES OF CLASS A SHARES. An investor who has made a Large Purchase of Class A shares of a Category I, II or IV Fund, will not be subject to a CDSC upon the redemption of those shares in the following situations:

- Redemptions of shares of Category I, II or IV Funds held more than 18 months;

- Redemptions of shares held by retirement plans, maintained pursuant to Sections 403 (only if the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code), 401 or 457 of the Code, in cases where (i) the plan has remained invested in Class A shares of a Fund for at least 12 months, or (ii) the redemption is not a complete redemption of shares held by the plan;

- Redemptions of shares by the investor where the investor's dealer waives the amounts otherwise payable to it by the distributor and notifies the distributor prior to the time of investment;

- Minimum required distributions made in connection with an IRA, Keogh Plan or custodial account under Section 403(b) of the Code or other retirement plan following attainment of age 70 1/2;

- Amounts from a monthly, quarterly or annual Systematic Redemption Plan of up to an annual amount of 12% of the account value on a per fund basis provided the investor reinvests his dividends. At the time the withdrawal plan is established, the total account value must be $5,000 or more.

CONTINGENT DEFERRED SALES CHARGE EXCEPTIONS FOR CLASS B AND C SHARES. CDSCs will not apply to the following redemptions of Class B or Class C shares, as applicable:

- Additional purchases of Class C shares of AIM International Core Equity Fund and AIM Real Estate Fund by shareholders of record on April 30, 1995, of AIM International Value Fund, predecessor to AIM International Core Equity Fund, and AIM Real Estate Fund, except that shareholders whose broker-dealers maintain a single omnibus account with Invesco Aim Investment Services on behalf of those shareholders, perform sub-accounting functions with respect to those shareholders, and are unable to segregate shareholders of record prior to April 30, 1995, from shareholders whose accounts were opened after that date will be subject to a CDSC on all purchases made after March 1, 1996;

- Redemptions following the death or post-purchase disability of (1) any registered shareholders on an account or (2) a settlor of a living trust, of shares held in the account at the time of death or initial determination of post-purchase disability, provided that shares have not been commingled with shares that are subject to CDSC;

- Certain distributions from individual retirement accounts, Section 403(b) retirement plans, Section 457 deferred compensation plans and
Section 401 qualified plans, where redemptions result from (i) required minimum distributions to plan participants or beneficiaries who are age 70 1/2 or older, and only with respect to that portion of such distributions that does not exceed 12% annually of the participant's or beneficiary's account value in a particular

61

Fund; (ii) in kind transfers of assets where the participant or beneficiary notifies the distributor of the transfer no later than the time the transfer occurs; (iii) tax-free rollovers or transfers of assets to another plan of the type described above invested in Class B or Class C shares of one or more of the Funds; (iv) tax-free returns of excess contributions or returns of excess deferral amounts; and (v) distributions on the death or disability (as defined in the Code) of the participant or beneficiary;

- Redemptions of Class C shares of a Fund other than AIM LIBOR Alpha Fund or AIM Short Term Bond Fund if you received such Class C shares by exchanging Class C shares of AIM LIBOR Alpha Fund or AIM Short Term Bond Fund.

CONTINGENT DEFERRED SALES CHARGE EXCEPTIONS FOR CLASS R SHARES. CDSCs will

not apply to the following redemptions of Class R shares:

- A total or partial redemption of Class R shares where the retirement plan's dealer of record notifies the distributor prior to the time of investment that the dealer waives the upfront payment otherwise payable to him; and

- Redemptions of shares held by retirement plans, maintained pursuant to Sections 403 (only if the employer or plan sponsor is a tax-exempt organization operated pursuant to Section 501(c)(3) of the Code), 401 or 457 of the Code, in cases where (i) the plan has remained invested in Class R shares of a Fund for at least 12 months, or (ii) the redemption is not a complete redemption of all Class R shares held by the plan.

General Information Regarding Purchases, Exchanges and Redemptions

GOOD ORDER. Purchase, exchange and redemption orders must be received in good order in accordance with Invesco Aim Investment Services policy and procedures and U.S. regulations. Invesco Aim Investment Services reserves the right to refuse transactions. Transactions not in good order will not be processed and once brought into good order, will receive current price. To be in good order, an investor or financial intermediary must supply Invesco Aim Investment Services with all required information and documentation, including signature guarantees when required. In addition, if a purchase of shares is made by check, the check must be received in good order. This means that the check must

62

be properly completed and signed, and legible to Invesco Aim Investment Services in its sole discretion. If a check used to purchase shares does not clear, or if any investment order must be canceled due to nonpayment, the investor will be responsible for any resulting loss.

AUTHORIZED AGENTS. Invesco Aim Investment Services and Invesco Aim Distributors may authorize agents to accept purchase and redemption orders that are in good form on behalf of the AIM Funds. In certain cases, these authorized agents are authorized to designate other intermediaries to accept purchase and redemption orders on a Fund's behalf. The Fund will be deemed to have received the purchase or redemption order when the Fund's authorized agent or its designee accepts the order. The order will be priced at the net asset value next determined after the order is accepted by the Fund's authorized agent or its designee.

SIGNATURE GUARANTEES. In addition to those circumstances listed in the "Shareholder Information" section of each Fund's prospectus, signature guarantees are required in the following situations: (1) requests to transfer the registration of shares to another owner; (2) telephone exchange and telephone redemption authorization forms; (3) changes in previously designated wiring or electronic funds transfer instructions; (4) written redemptions or exchanges of shares held in certificate form previously reported to Invesco Aim as lost, whether or not the redemption amount is under $250,000 or the proceeds are to be sent to the address of record; and (5) requests to redeem accounts where the proceeds are over $250,000 or the proceeds are to be sent to an address or a bank other than the address or bank of record. AIM Funds may waive or modify any signature guarantee requirements at any time.

Acceptable guarantors include banks, broker-dealers, credit unions, national securities exchanges, savings associations and any other organization, provided that such institution or organization qualifies as an "eligible guarantor institution" as that term is defined in rules adopted by the SEC, and further provided that such guarantor institution is listed in one of the reference guides contained in Invesco Aim Investment Services' current Signature Guarantee Standards and Procedures, such as certain domestic banks, credit unions, securities dealers, or securities exchanges. Notary public signatures are not an acceptable replacement for a signature guarantee. Invesco Aim Investment Services will also accept signatures with either: (1) a signature guaranteed with a medallion stamp of the STAMP Program, or (2) a signature guaranteed with a medallion stamp of the NYSE Medallion Signature Program, provided that in either event, the amount of the total transaction involved does not exceed the surety coverage amount indicated on the medallion. For information regarding whether a particular institution or organization qualifies as an "eligible guarantor institution" and to determine how to fulfill a signature guarantee requirement, an investor should contact the Client Services Department of Invesco Aim Investment Services.

TRANSACTIONS BY TELEPHONE. By signing an account application form, an investor appoints Invesco Aim Investment Services as his true and lawful attorney-in-fact to surrender for redemption any and all unissued shares held by Invesco Aim Investment Services in the designated account(s), or in any other account with any of the AIM Funds, present or future, which has the identical registration as the designated account(s), with full power of substitution in the premises. Invesco Aim Investment Services and Invesco Aim Distributors are thereby authorized and directed to accept and act upon any telephone redemptions of shares held in any of the account(s) listed, from any person who requests the redemption proceeds to be applied to purchase shares in any one or more of the AIM Funds, provided that such fund is available for sale and provided that the registration and mailing address of the shares to be purchased are identical to the registration of the shares being redeemed. An investor acknowledges by signing the form that he understands and agrees that Invesco Aim Investment Services and Invesco Aim Distributors may not be liable for any loss, expense or cost arising out of any telephone exchange requests effected in accordance with the authorization set forth in these instructions if they reasonably believe such request to be genuine, but may in certain cases be liable for losses due to unauthorized or fraudulent transactions. Procedures for verification of telephone transactions may include recordings of telephone transactions (maintained for six months), requests for confirmation of the shareholder's Social Security Number and current address, and mailings of confirmations promptly after the transactions. Invesco Aim Investment Services reserves the right to modify or terminate the telephone exchange privilege at any time without

63

notice. An investor may elect not to have this privilege by marking the appropriate box on the application. Then any exchanges must be effected in writing by the investor.

INTERNET TRANSACTIONS. An investor may effect transactions in his account through the internet by establishing a Personal Identification Number (PIN). By establishing a PIN the investor acknowledges and agrees that neither Invesco Aim Investment Services nor Invesco Aim Distributors will be liable for any loss, expense or cost arising out of any internet transaction effected by them in accordance with any instructions submitted by a user who transmits the PIN as authentication of his or her identity. Procedures for verification of internet transactions include requests for confirmation of the shareholder's personal identification number and mailing of confirmations promptly after the transactions. The investor also acknowledges that the ability to effect internet transactions may be terminated at any time by the AIM Funds. Policies for processing transactions via the Internet may differ from policies for transactions via telephone due to system settings.

ABANDONED PROPERTY. It is the responsibility of the investor to ensure that Invesco Aim Investment Services maintains a correct address for his account(s). An incorrect address may cause an investor's account statements and other mailings to be returned to Invesco Aim Investment Services. Upon receiving returned mail, Invesco Aim Investment Services will attempt to locate the investor or rightful owner of the account. If unsuccessful, Invesco Aim Investment Services will retain a shareholder locator service with a national information database to conduct periodic searches for the investor. If the search firm is unable to locate the investor, the search firm will determine whether the investor's account has legally been abandoned. Invesco Aim Investment Services is legally obligated to escheat (or transfer) abandoned property to the appropriate state's unclaimed property administrator in accordance with statutory requirements. The investor's last known address of record determines which state has jurisdiction.

MISCELLANEOUS FEES. In certain circumstances, the intermediary maintaining the shareholder account through which your Fund shares are held may assess various fees related to the maintenance of that account, such as:

- an annual custodial fee on accounts where Invesco Aim Distributors acts as the prototype sponsor;

- expedited mailing fees in response to overnight redemption requests; and

- copying and mailing charges in response to requests for duplicate statements.

Please consult with your intermediary for further details concerning any applicable fees.

INSTITUTIONAL CLASS SHARES

Before the initial purchase of shares, an investor must submit a completed account application to his financial intermediary, who should forward the application to Invesco Aim Investment Services, Inc. at P.O. Box 4497, Houston, Texas 77210-4497. An investor may change information in his account application by submitting written changes or a new account application to his intermediary or to Invesco Aim Investment Services.

Purchase and redemption orders must be received in good order. To be in good order, the financial intermediary must give Invesco Aim Investment Services all required information and documentation with respect to the investor. If the intermediary fails to deliver the investor's payment on the required settlement date, the intermediary must reimburse the Fund for any overdraft charges incurred.

64

A financial intermediary may submit a written request to Invesco Aim Investment Services for correction of transactions involving Fund shares. If Invesco Aim Investment Services agrees to correct a transaction, and the correction requires a dividend adjustment, the intermediary must agree in writing to reimburse the Fund for any resulting loss.

An investor may terminate his relationship with an intermediary and become the shareholder of record on his account. However, until the investor establishes a relationship with an intermediary, the investor will not be able to purchase additional shares of the Fund, except through the reinvestment of distributions.

Payment for redeemed shares is normally made by Federal Reserve wire to the bank account designated in the investor's account application, but may be sent by check at the investor's request. By providing written notice to his financial intermediary or to Invesco Aim Investment Services, an investor may change the bank account designated to receive redemption proceeds. Invesco Aim Investment Services may request additional documentation.

Invesco Aim Investment Services may request that an intermediary maintain separate master accounts in the Fund for shares held by the intermediary (a) for its own account, for the account of other institutions and for accounts for which the intermediary acts as a fiduciary; and (b) for accounts for which the intermediary acts in some other capacity. An intermediary may aggregate its master accounts and sub-accounts to satisfy the minimum investment requirement.

Platform sponsors that provide investment vehicles to fund Section 401 defined contribution plans and have entered into written agreements with Invesco Aim Distributors to waive applicable investment minimums may purchase Institutional Class shares for accounts within such plans.

OFFERING PRICE

The following formula may be used to determine the public offering price per Class A share of an investor's investment:

Net Asset Value / (1 - Sales Charge as % of Offering Price ) = Offering Price.

For example, at the close of business on March 31, 2008, AIM High Income Municipal Fund - Class A shares had a net asset value per share of $8.20. The offering price, assuming an initial sales charge of 4.75%, therefore was $8.61.

Institutional Class shares of the Funds are offered at net asset value.

Calculation of Net Asset Value

AIM Tax-Exempt Cash Fund uses the amortized cost method to determine its net asset value. Under the amortized cost method, each investment is valued at its cost and thereafter any discount or premium is amortized on a constant basis to maturity. While this method provides certainty of valuation, it may result in periods in which the amortized cost value of the Fund's investments is higher or lower than the price that would be received if the investments were sold. During periods of declining interest rates, use by the Fund of the amortized cost method of valuing its portfolio may result in a lower value than the market value of the portfolio, which could be an advantage to new investors relative to existing shareholders. The converse would apply in a period of rising interest rates.

The Fund may use the amortized cost method to determine its net asset value so long as the Fund does not (a) purchase any instrument with a remaining maturity greater than 397 days (for these purposes, repurchase agreements shall not be deemed to involve the purchase by the Fund of the securities pledged as collateral in connection with such agreements) or (b) maintain a dollar-weighted average portfolio maturity in excess of 90 days, and otherwise complies with the terms of rules adopted by the SEC.

65

The Board has established procedures designed to stabilize the AIM Tax-Exempt Cash Fund's net asset value per share at $1.00, to the extent reasonably possible. Such procedures include review of portfolio holdings by the trustees at such intervals as they may deem appropriate. The reviews are used to determine whether net asset value, calculated by using available market quotations, deviates from $1.00 per share and, if so, whether such deviation may result in material dilution or is otherwise unfair to investors or existing shareholders. In the event the trustees determine that a material deviation exists, they intend to take such corrective action as they deem necessary and appropriate. Such actions may include selling portfolio securities prior to maturity in order to realize capital gains or losses or to shorten average portfolio maturity, withholding dividends, redeeming shares in kind, or establishing a net asset value per share by using available market quotations, in which case the net asset value could possibly be more or less than $1.00 per share. AIM Tax-Exempt Cash Fund intends to comply with any amendments made to Rule 2a-7 which may require corresponding changes in the Fund's procedures which are designed to stabilize the Fund's price per share at $1.00.

Under the amortized cost method, each investment is valued at its cost and thereafter any discount or premium is amortized on a constant basis to maturity. While this method provides certainty of valuation, it may result in periods in which the amortized cost value of the Fund's investments is higher or lower than the price that would be received if the investments were sold.

AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund each determine their net asset value per share once daily as of the close of the customary trading session of the NYSE (generally 4:00 p.m. Eastern time) on each business day of the Funds. In the event the NYSE closes early (i.e., before 4:00
p.m. Eastern time) on a particular day, each Fund determines its net asset value per share as of the close of the NYSE on such day. For purposes of determining net asset value per share, futures and options contract may be valued 15 minutes after the close of the customary trading session of the NYSE. Futures contracts are valued at the final settlement price set by an exchange on which they are principally traded. Listed options are valued at the mean between the last bid and ask prices from the exchange on which they are principally traded. Options not listed on an exchange are valued by an independent source at the mean between the last bid and ask prices. The Funds determine net asset value per share by dividing the value of a Fund's securities, cash and other assets (including interest accrued but not collected) attributable to a particular class, less all its liabilities (including accrued expenses and dividends payable) attributable to that class, by the total number of shares outstanding of that class. Determination of a Fund's net asset value per share is made in accordance with generally accepted accounting principles. Generally, the portfolio securities for non-money market funds are recorded in the NAV no later than trade date plus one, except on fiscal quarter ends, such securities are recorded on trade date. For money market funds, portfolio securities are recorded in the NAV on trade date. The net asset value for shareholder transactions may be different than the net asset value reported in the Fund's financial statements due to adjustments required by generally accepted accounting principles made to the net asset value of the Fund at period end.

Investments in open-end and closed-end registered investment companies that do not trade on an exchange are valued at the end of day net asset value per share. Investments in open-end and closed-end registered investment companies that trade on an exchange are valued at the last sales price or official closing price as of the close of the customary trading session on the exchange where the security is principally traded.

A security listed or traded on an exchange (excluding convertible bonds) held by a Fund is valued at its last sales price or official closing price on the exchange where the security is principally traded or, lacking any sales or official closing price on a particular day, the security may be valued at the closing bid price on that day. Each equity security traded in the over-the-counter market is valued on the basis of prices furnished by independent pricing services vendors or market makers. Debt securities (including convertible bonds) and unlisted equities are fair valued using an evaluated quote on the basis of prices provided by an independent pricing vendor. Evaluated quotes provided by the pricing vendors may be determined without exclusive reliance on quoted prices, and may reflect appropriate factors such as institution-size trading in similar groups of securities, developments related to special securities, dividend

66

rate, yield, quality, coupon rate, maturity, type of issue, individual trading characteristics and other market data.

Securities for which market prices are not provided by any of the above methods may be valued based upon quotes furnished by independent sources and are valued at the last bid price in the case of equity securities and in the case of debt obligations, the mean between the last bid and ask prices.

Short-term investments (including commercial paper) are valued at amortized cost where the security has 60 days or less to maturity.

Generally, trading in corporate bonds, U.S. Government securities and money market instruments is substantially completed each day at various times prior to the close of the customary trading session of the NYSE. The values of such securities used in computing the net asset value of a Fund's shares are determined at such times. Occasionally, events affecting the values of such securities may occur between the times at which such values are determined and the close of the customary trading session of the NYSE. If Invesco Aim believes a development/event has actually caused a closing price to no longer reflect current market value, the closing prices may be adjusted to reflect the fair value of the affected security as of the close of the NYSE as determined in good faith using procedures approved by the Board.

Securities for which market quotations are not readily available or are unreliable are valued at fair value as determined in good faith by or under the supervision of the Trust's officers in accordance with procedures approved by the Board of Trustees. Issuer specific events, market trends, bid/ask quotes of brokers and information providers and other market data may be reviewed in the course of making a good faith determination of a security's fair value.

REDEMPTIONS IN KIND

Although the Funds generally intend to pay redemption proceeds solely in cash, the Funds reserve the right to determine, in their sole discretion, whether to satisfy redemption requests by making payment in securities or other property (known as a redemption in kind). For instance, a Fund may make a redemption in kind if a cash redemption would disrupt its operations or performance. Securities that will be delivered as payment in redemptions in kind will be valued using the same methodologies that the Fund typically utilizes in valuing such securities. Shareholders receiving such securities are likely to incur transaction and brokerage costs on their subsequent sales of such securities, and the securities may increase or decrease in value until the shareholder sells them. The Trust, on behalf of AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund, has made an election under Rule 18f-1 under the 1940 Act (a "Rule 18f-1 Election"), and therefore, the Trust, on behalf of such Funds, is obligated to redeem for cash all shares presented to such Fund for redemption by any one shareholder in an amount up to the lesser of $250,000 or 1% of that Fund's net assets in any 90-day period. The Rule 18f-1 Election is irrevocable while Rule 18f-1 under the 1940 Act is in effect unless the SEC by order permits withdrawal of such Rule 18f-1 Election.

BACKUP WITHHOLDING

Accounts submitted without a correct, certified taxpayer identification number or, alternatively, a completed and currently effective Internal Revenue Service ("IRS") Form W-8 (for non-resident aliens) or Form W-9 (for U.S. persons including resident aliens) accompanying the registration information will generally be subject to backup withholding.

Each AIM Fund and other payers, generally, must withhold 28% of reportable dividends (whether paid in cash or reinvested in additional Fund shares), including exempt-interest dividends, in the case of any shareholder who fails to provide the Fund with a taxpayer identification number ("TIN") and a certification that he is not subject to backup withholding.

67

An investor is subject to backup withholding if:

1. the investor fails to furnish a correct TIN to the Fund;

2. the IRS notifies the Fund that the investor furnished an incorrect TIN;

3. the investor or the Fund is notified by the IRS that the investor is subject to backup withholding because the investor failed to report all of the interest and dividends on such investor's tax return (for reportable interest and dividends only);

4. the investor fails to certify to the Fund that the investor is not subject to backup withholding under (3) above (for reportable interest and dividend accounts opened after 1983 only); or

5. the investor does not certify his TIN. This applies only to non-exempt mutual fund accounts opened after 1983.

Interest and dividend payments are subject to backup withholding in all five situations discussed above. Redemption proceeds are subject to backup withholding only if (1), (2) or (5) above applies.

Certain payees and payments are exempt from backup withholding and information reporting. Invesco Aim or Invesco Aim Investment Services will not provide Form 1099 to those payees.

Investors should contact the IRS if they have any questions concerning withholding.

IRS PENALTIES - Investors who do not supply the AIM Funds with a correct TIN will be subject to a $50 penalty imposed by the IRS unless such failure is due to reasonable cause and not willful neglect. If an investor falsifies information on this form or makes any other false statement resulting in no backup withholding on an account which should be subject to backup withholding, such investor may be subject to a $500 penalty imposed by the IRS and to certain criminal penalties including fines and/or imprisonment.

NON-RESIDENT ALIENS - Non-resident alien individuals and foreign entities with a valid Form W-8 are not subject to the backup withholding previously discussed. The Form W-8 generally remains in effect for a period starting on the date the Form is signed and ending on the last day of the third succeeding calendar year. Such shareholders may, however, be subject to federal income tax withholding at a 30% rate on ordinary income dividends and other distributions. Under applicable treaty law, residents of treaty countries may qualify for a reduced rate of withholding or a withholding exemption. Nonresident alien individuals and some foreign entities failing to provide a valid Form W-8 may be subject to backup withholding and Form 1099 reporting.

DIVIDENDS, DISTRIBUTIONS AND TAX MATTERS

DIVIDENDS AND DISTRIBUTIONS

Each Fund intends to declare daily and pay monthly net investment income dividends and declare and pay annually any capital gain distributions; however each Fund may declare and pay such capital gains distributions more than once per year, if necessary, in order to reduce or eliminate federal excise or income taxes on a Fund. It is AIM Tax-Exempt Cash Fund's intention to distribute substantially all of its investment company taxable income and capital gain net income (excess capital gains over capital losses). AIM High Income Municipal Fund and AIM Tax-Free Intermediate Fund intend to distribute a significant portion of their net investment income and capital gains net income. In determining the amount of capital gains, if any, available for distribution, capital gains will generally be offset against available net capital losses, if any, carried forward from previous fiscal periods. All dividends and distributions will be automatically reinvested in additional shares of the same class of each Fund unless the shareholder has requested in writing to receive such dividends and distributions in cash or that they be invested in shares of another AIM Fund, subject to the terms and conditions set forth in the Prospectus under the caption "Purchasing Shares - Automatic Dividend and Distribution Investment."

Such dividends and distributions will be reinvested at the net asset value per share determined on the ex-dividend date. If a shareholder's account does not have any shares in it on a dividend or capital gain distribution payment date, the dividend or distribution will be paid in cash whether or not the shareholder has elected to have such dividends or distributions reinvested.

For each Fund, dividends will begin accruing on the first business day after the purchase order for shares of the Fund is effective (settle date), and accrue up to and including the business day to which a redemption order is effective (settle date). Thus, if a purchase order is effective on Friday dividends will begin accruing on Monday (unless Monday is not a business day of the Fund).

Dividends on Class B and Class C shares are expected to be lower than those for Class A or Class A3 shares because of higher distribution fees paid by Class B and Class C shares. Other class-specific expenses may also affect dividends on shares of those classes. Expenses attributable to a particular class ("Class Expenses") include distribution plan expenses, which must be allocated to the class for which they are incurred. Other expenses may be allocated as Class Expenses, consistent with applicable legal principles under the 1940 Act and the Code.

TAX MATTERS

The following is only a summary of certain additional tax considerations generally affecting the Funds and their shareholders that are not described in the Prospectus. No attempt is made to present a detailed explanation of the tax treatment of each Fund or its shareholders, and the discussion here and in the Prospectus is not intended as a substitute for careful tax planning.

QUALIFICATION AS A REGULATED INVESTMENT COMPANY. Each Fund has elected to be taxed under Subchapter M of the Code as a regulated investment company and intends to maintain its qualification as such in each of its taxable years. As a regulated investment company, each Fund is not subject to federal income tax on the portion of its net investment income (i.e., taxable interest, dividends and other taxable ordinary income, net of expenses) and capital gain net income (excess of capital gains over capital losses) that it distributes to shareholders, provided that it distributes an amount equal to (i) at least 90% of its investment company taxable income (i.e., net investment income, net foreign currency ordinary gain or loss and the excess of net short-term capital gain over net long-term capital loss) and (ii) at least 90% of the excess of its tax-exempt interest income under Code Section 103(a) over its deductions disallowed under Code Sections 265 and 171(a)(2) for the taxable year (the "Distribution Requirement"), and satisfies certain other requirements of the Code that are described below. Distributions by a Fund made during the taxable year or, under specified circumstances, within twelve months after the close of the taxable year, will be considered distributions of income and gain of the taxable year and can therefore satisfy the Distribution Requirement. Notwithstanding the foregoing, the Board of Trustees reserves the right not to maintain the qualification of a Fund as a regulated investment company if it determines such a course of action to be beneficial to shareholders.

Each Fund presently intends to elect under applicable Treasury regulations to treat any net capital loss and any net long-term capital loss incurred after October 31 as if it had been incurred in the succeeding taxable year in determining its taxable income from the current taxable year. Certain Funds may also elect under the same regulations to treat all or part of any net foreign currency loss incurred after October 31 as if it had been incurred in the succeeding taxable year.

Each Fund may use "equalization accounting" in determining the portion of its net investment income and capital gain net income that has been distributed. A Fund that elects to use equalization accounting will allocate a portion of its realized investment income and capital gain to redemptions of Fund shares and will reduce the amount of such income and/or gain that it distributes in cash. However, each Fund intends to make cash distributions for each taxable year in an aggregate amount that is sufficient to satisfy the Distribution Requirement without taking into account its use of equalization accounting. The IRS has not published any guidance concerning the methods to be used in allocating investment income and capital gain to redemptions of shares. In the event that the IRS determines that a

69

Fund is using an improper method of allocation and has under-distributed its net investment income or capital gain net income for any taxable year, such Fund may be liable for additional federal income tax.

In addition to satisfying the Distribution Requirement, a regulated investment company must derive at least 90% of its gross income from dividends, interest, certain payments with respect to securities loans, and gains from the sale or other disposition of stock, securities, or foreign currencies (to the extent such foreign currency gain is directly related to the regulated investment company's principal business of investing in stock or securities), or other income (including, but not limited to, gains from options, futures or forward contracts) derived from its business of investing in such stock, securities or currencies and net income derived from certain publicly traded partnerships (the "Income Requirement"). Under certain circumstances, a Fund may be required to sell portfolio holdings to meet this requirement.

In addition to satisfying the requirements described above, each Fund must satisfy an asset diversification test in order to qualify as a regulated investment company (the "Asset Diversification Test"). Under this test, at the close of each quarter of each Fund's taxable year, at least 50% of the value of the Fund's assets must consist of cash and cash items, U.S. Government securities, securities of other regulated investment companies, and securities of other issuers, as to which the Fund has not invested more than 5% of the value of the Fund's total assets in securities of such issuer and as to which the Fund does not hold more than 10% of the outstanding voting securities of such issuer, and no more than 25% of the value of its total assets may be invested in the securities of any one issuer (other than U.S. Government securities and securities of other regulated investment companies) or of two or more issuers which the Fund controls and which are engaged in the same or similar trades or businesses, or, collectively, in securities of certain publicly traded partnerships.

For purposes of the Asset Diversification Test, the IRS has ruled that the issuer of a purchased listed call option on stock is the issuer of the stock underlying the option. The IRS has also informally ruled that, in general, the issuers of purchased or written call and put options on securities, of long and short positions on futures contracts on securities and of options on such futures contracts are the issuers of the securities underlying such financial instruments where the instruments are traded on an exchange.

Where the writer of a listed call option owns the underlying securities, the IRS has ruled that the Asset Diversification Test will be applied solely to such securities and not to the value of the option itself. With respect to options on securities indexes, futures contracts on securities indexes and options on such futures contracts, the IRS has informally ruled that the issuers of such options and futures contracts are the separate entities whose securities are listed on the index, in proportion to the weighting of securities in the computation of the index. It is clear under present law who should be treated as the issuer of forward foreign currency exchange contracts, of options on foreign currencies, or of foreign currency futures and related options. It has been suggested that the issuer in each case may be the foreign central bank or the foreign government backing the particular currency. Due to this uncertainty and because the Funds may not rely on informal rulings of the IRS, the Funds may find it necessary to seek a ruling from the IRS as to the application of the Asset Diversification Test to certain of the foregoing types of financial instruments or to limit its holdings of some or all such instruments in order to stay within the limits of such test.

Under an IRS revenue procedure, a Fund may treat its position as lender under a repurchase agreement as a U.S. Government security for purposes of the Asset Diversification Test where the repurchase agreement is fully collateralized (under applicable SEC standards) with securities that constitute U.S. Government securities.

If for any taxable year a Fund does not qualify as a regulated investment company, all of its taxable income (including its net capital gain (net long-term capital gain over any net short-term capital loss)) would be subject to tax at regular corporate rates without any deduction for distributions to shareholders, and such distributions would be taxable as ordinary dividends to the extent of such Fund's current and accumulated earnings and profits. Such distributions generally would be eligible for the dividends received deduction in the case of corporate shareholders and would be included in the qualified dividend income of non-corporate shareholders. See "Fund Distributions" below.

DETERMINATION OF TAXABLE INCOME OF A REGULATED INVESTMENT COMPANY. In general, gain or loss recognized by a Fund on the disposition of an asset will be a capital gain or loss. However, gain recognized on the disposition of a debt obligation purchased by a Fund at a market discount (generally, at a price less than its principal amount) will be treated as ordinary income to the extent of the portion of the market discount which accrued during the period of time the Fund held the debt obligation unless the Fund made an election to accrue market discount into income. If a Fund purchases a debt obligation that was originally issued at a discount, the Fund is generally required to include in gross income each year the portion of the original issue discount which accrues during such year. In addition, under the rules of Code Section 988, gain or loss recognized on the disposition of a debt obligation denominated in a foreign currency or an option with respect thereto (but only to the extent attributable to changes in foreign currency exchange rates), and gain or loss recognized on the disposition of a forward foreign currency contract or of foreign currency itself, will generally be treated as ordinary income or loss. In certain cases, a Fund may make an election to treat such gain or loss as capital.

Certain hedging transactions that may be engaged in by certain of the Funds (such as short sales "against the box") may be subject to special tax treatment as "constructive sales" under Section 1259 of the Code if a Fund holds certain "appreciated financial positions" (defined generally as any interest (including a futures or forward contract, short sale or option) with respect to stock, certain debt instruments, or partnership interests if there would be a gain were such interest sold, assigned, or otherwise terminated at its fair market value). Upon entering into a constructive sales transaction with respect to an appreciated financial position, a Fund will generally be deemed to have constructively sold such appreciated financial position and will recognize gain as if such position were sold, assigned, or otherwise terminated at its fair market value on the date of such constructive sale (and will take into account any gain for the taxable year which includes such date).

Some of the forward foreign currency exchange contracts, options and futures contracts that certain of the Funds may enter into will be subject to special tax treatment as "Section 1256 contracts." Section 1256 contracts that a Fund holds are treated as if they are sold for their fair market value on the last business day of the taxable year, regardless of whether a taxpayer's obligations (or rights) under such contracts have terminated (by delivery, exercise, entering into a closing transaction or otherwise) as of such date. Any gain or loss recognized as a consequence of the year-end deemed disposition of
Section 1256 contracts is combined with any other gain or loss that was previously recognized upon the termination of Section 1256 contracts during that taxable year. The net amount of such gain or loss for the entire taxable year (including gain or loss arising as a consequence of the year-end deemed sale of such contracts) is deemed to be 60% long-term and 40% short-term gain or loss. However, in the case of Section 1256 contracts that are forward foreign currency exchange contracts, the net gain or loss is separately determined and (as discussed above) generally treated as ordinary income or loss unless certain elections have been made. If such a future or option is held as an offsetting position and can be considered a straddle under Section 1092 of the Code, such a straddle will constitute a mixed straddle. A mixed straddle will be subject to both Section 1256 and Section 1092 unless certain elections are made by the Fund.

Other hedging transactions in which the Funds may engage may result in "straddles" or "conversion transactions" for U.S. federal income tax purposes. The straddle and conversion transaction rules may affect the character of gains (or in the case of the straddle rules, losses) realized by the Funds. In addition, losses realized by the Funds on positions that are part of a straddle may be deferred under the straddle rules, rather than being taken into account in calculating the taxable income for the taxable year in which the losses are realized. Because only a few regulations implementing the straddle rules and the conversion transaction rules have been promulgated, the tax consequences to the Funds of hedging transactions are not entirely clear. The hedging transactions may increase the amount of short-term capital gain realized by the Funds (and, if they are conversion transactions, the amount of ordinary income) which is taxed as ordinary income when distributed to shareholders.

Because application of any of the foregoing rules governing Section 1256 contracts, constructive sales, straddle and conversion transactions may affect the character of gains or losses, defer losses

71

and/or accelerate the recognition of gains or losses from the affected investment or straddle positions, the taxable income of a Fund may exceed or be less than its book income. Accordingly, the amount which must be distributed to shareholders and which will be taxed to shareholders as ordinary income or long-term capital gain may also differ from the book income of the Fund and may be increased or decreased as compared to a fund that did not engage in such transactions.

EXCISE TAX ON REGULATED INVESTMENT COMPANIES. A 4% non-deductible excise tax is imposed on a regulated investment company that fails to distribute in each calendar year an amount equal to 98% of ordinary taxable income for the calendar year and 98% of capital gain net income for the one-year period ended on October 31 of such calendar year (or, at the election of a regulated investment company having a taxable year ending November 30 or December 31, for its taxable year (a "taxable year election")). The balance of such income must be distributed during the next calendar year. For the foregoing purposes, a regulated investment company is treated as having distributed any amount on which it is subject to income tax for any taxable year ending in such calendar year.

For purposes of the excise tax, a regulated investment company shall (1) reduce its capital gain net income (but not below its net capital gain) by the amount of any net ordinary loss for the calendar year and (2) exclude Section 988 foreign currency gains and losses incurred after October 31 (or after the end of its taxable year if it has made a taxable year election) in determining the amount of ordinary taxable income for the current calendar year (and, instead, include such gains and losses in determining ordinary taxable income for the succeeding calendar year).

Each Fund generally intends to make sufficient distributions or deemed distributions of its ordinary taxable income and capital gain net income prior to the end of each calendar year to avoid liability for the excise tax. However, in the event that the IRS determines that a Fund is using an improper method of allocation for purposes of equalization accounting (as discussed above), such Fund may be liable for excise tax. Moreover, investors should note that a Fund may in certain circumstances be required to liquidate portfolio investments to make sufficient distributions to avoid excise tax liability. In addition, under certain circumstances, a Fund may elect to pay a minimal amount of excise tax.

FUND DISTRIBUTIONS. Each Fund intends to qualify to pay "exempt-interest dividends" by satisfying the requirement that at the close of each quarter of a Fund's taxable year at least 50% of a Fund's total assets consists of Municipal Securities, which are exempt from federal income tax. Distributions from a Fund will constitute exempt-interest dividends to the extent of a Fund's tax-exempt interest income (net of allocable expenses and amortized bond premium). Exempt-interest dividends distributed to a Fund's shareholders are excluded from gross income for federal income tax purposes. However, shareholders required to file a federal income tax return will be required to report the receipt of exempt-interest dividends on their returns. Moreover, while exempt-interest dividends are excluded from gross income for federal income tax purposes, they may be subject to AMT in certain circumstances and may have other collateral tax consequences as discussed below. Distributions by a Fund of any investment company taxable income or of any net capital gain will be taxable to shareholders as discussed below.

AMT is imposed in addition to, but only to the extent it exceeds, the regular tax and is computed at a maximum rate of 28% for non-corporate taxpayers and 20% for corporate taxpayers on the excess of the taxpayer's alternative minimum taxable income ("AMTI") over an exemption amount. However, the AMT on capital gain dividends paid by a Fund to a non-corporate shareholder may not exceed the maximum applicable capital gains rate for non-corporate taxpayers. Exempt-interest dividends derived from certain "private activity" Municipal Securities issued after August 7, 1986 will generally constitute an item of tax preference includable in AMTI for both corporate and non-corporate taxpayers. In addition, exempt-interest dividends derived from all Municipal Securities, regardless of the date of issue, must be included in adjusted current earnings, which are used in computing an additional corporate preference item (i.e., 75% of the excess of a corporate taxpayer's adjusted current earnings over its AMTI (determined without regard to this item and the AMT net operating loss deduction)) includable in AMTI. Pursuant to the Taxpayer Relief Act of 1997, certain small corporations are wholly exempt from the AMT.

72

Exempt-interest dividends must be taken into account in computing the portion, if any, of social security or railroad retirement benefits that must be included in an individual shareholder's gross income is subject to federal income tax. Further, a shareholder of a Fund is denied a deduction for interest on indebtedness incurred or continued to purchase or carry shares of such Fund. Moreover, a shareholder who is (or is related to) a "substantial user" of a facility financed by industrial development bonds held by a Fund will likely be subject to tax on dividends paid by that Fund which are derived from interest on such bonds. Receipt of exempt-interest dividends may result in other collateral federal income tax consequences to certain taxpayers, including financial institutions, property and casualty insurance companies and foreign corporations engaged in a trade or business in the United States. Prospective investors should consult their own tax advisers as to such consequences.

Failure of the issuer of a tax-exempt security to comply with certain legal or contractual requirements relating to a Municipal Security could cause interest on the Municipal Security, as well as Fund distributions derived from this interest, to become taxable, perhaps retroactively to the date the Municipal Security was issued. In such a case, a Fund may be required to report to the IRS and send to shareholders amended Forms 1099 for a prior taxable year in order to report additional taxable income. This, in turn, could require shareholders to file amended federal and state income tax returns for such prior year to report and pay tax and interest on their pro rata share of the additional amount of taxable income.

To the extent that exempt-interest dividends are derived from interest on obligations of a state or its political subdivisions, or from interest on qualifying U.S. territorial obligations (including qualifying obligations of Puerto Rico, the U.S. Virgin Islands, and Guam), they also may be exempt from that state's personal income taxes. Most states, however, do not grant tax-free treatment to interest on state and municipal securities of other states. The right of a state to exempt from taxation interest on its own state and local obligations while taxing the interest on out-of-state municipal securities was affirmed by the U.S. Supreme Court in Kentucky v. Davis, decided May 19, 2008. However, the Supreme Court declined to address whether the in-state exemption for private activity bonds violates the Commerce Clause of the U.S. Constitution, leaving for future courts to consider any claim that differential treatment of interest on out-of-state private-activity bonds should be evaluated differently from the treatment of municipal bond interest generally.

Each Fund anticipates distributing substantially all of its investment company taxable income for each taxable year. Such distributions will be taxable to shareholders as ordinary income and treated as dividends for federal income tax purposes, but they will not qualify for the 70% dividends received deduction for corporations or be treated as qualified dividend income for non-corporate shareholders.

A Fund may either retain or distribute to shareholders its net capital gain (net long-term capital gain over net short-term capital loss) for each taxable year. Each Fund currently intends to distribute any such amounts. If net capital gain is distributed and designated as a "capital gain dividend", it will be taxable to shareholders as long-term capital gain (currently taxable at a maximum rate of 15% for noncorporate shareholders) regardless of the length of time the shareholder has held his shares or whether such gain was recognized by the Fund prior to the date on which the shareholder acquired his shares. Conversely, if a Fund elects to retain its net capital gain, the Fund will be taxed thereon (except to the extent of any available capital loss carry forwards) at the 35% corporate tax rate. If a Fund elects to retain its net capital gain, it is expected that the Fund also will elect to have shareholders treated as if each received a distribution of its pro rata share of such gain, with the result that each shareholder will be required to report its pro rata share of such gain on its tax return as long-term capital gain, will receive a refundable tax credit for its pro rata share of tax paid by the Fund on the gain, and will increase the tax basis for its shares by an amount equal to the deemed distribution less the tax credit.

Subject to applicable Code limitations, each Fund will be allowed to take into account a net capital loss (excess of losses over gains from the sale of capital assets) from a prior taxable year as a short-term capital loss for the current taxable year in determining its investment company taxable income and net capital gain.

73

Distributions by a Fund that are not made from earnings and profits will be treated as a return of capital to the extent of (and in reduction of) the shareholder's tax basis in his shares; any excess will be treated as gain from the sale of his shares. Investors should be aware, however, that if an amount of a Fund's distributions designated as exempt-interest dividends exceeds its net exempt interest for the taxable year, the amounts qualifying as exempt-interest will be scaled back ratably to the amount of the Fund's net tax-exempt income. Any such over distribution is taxable as ordinary income to the extent of the deductions disallowed to the Fund under Code Sections 265 (deductions allocable to exempt interest) and 171(a)(2) (amortizable bond premium on Municipal Securities) for the taxable year.

Distributions by a Fund will be treated in the manner described above regardless of whether such distributions are paid in cash or reinvested in additional shares of the Fund (or of another Fund). Shareholders receiving a distribution in the form of additional shares will be treated as receiving a distribution in an amount equal to the fair market value of the shares received, determined as of the ex-dividend date.

Ordinarily, shareholders are required to take distributions by a Fund into account in the year in which the distributions are made. However, dividends declared in October, November or December of any year and payable to shareholders of record on a specified date in such a month will be deemed to have been received by the shareholders (and made by the Fund) on December 31 of such calendar year if such dividends are actually paid in January of the following year. Shareholders will be advised annually as to the U.S. federal income tax consequences of distributions made (or deemed made) during the year in accordance with the guidance that has been provided by the IRS.

Income earned on certain U.S. government obligations is exempt from state and local personal income taxes if earned directly by you. States also grant tax-free status to dividends paid to you from interest earned on direct obligations of the U.S. government, subject in some states to minimum investment or reporting requirements that must be met by the Fund. Income on investments by the Fund in certain other obligations, such as repurchase agreements collateralized by U.S. government obligations, commercial paper and federal agency-backed obligations (e.g., Government National Mortgage Association (GNMA) or Federal National Mortgage Association (FNMA) obligations), generally does not qualify for tax-free treatment. The rules on exclusion of this income are different for corporations.

SALE OR REDEMPTION OF SHARES. A shareholder will recognize gain or loss on the sale or redemption of shares of a Fund in an amount equal to the difference between the proceeds of the sale or redemption and the shareholder's adjusted tax basis in the shares. All or a portion of any loss so recognized may be deferred under the wash sale rules if the shareholder purchases other shares of the Fund within 30 days before or after the sale or redemption. In general, any gain or loss arising from (or treated as arising from) the sale or redemption of shares of a Fund will be considered capital gain or loss and will be long-term capital gain or loss if the shares were held for longer than one year. Currently, any long-term capital gain recognized by a non-corporate shareholder will be subject to tax at a maximum rate of 15%. However, any capital loss arising from the sale or redemption of shares held for six months or less will be treated as a long-term capital loss to the extent of the amount of capital gain dividends received on such shares, and any such loss will be disallowed to the extent of any exempt-interest dividends that were received within the six-month period. Capital losses in any year are deductible only to the extent of capital gains plus, in the case of a non-corporate taxpayer, $3,000 of ordinary income.

The Transfer Agent may provide Fund shareholders with information concerning the average cost basis of their shares in order to help them calculate their gain or loss from a sale or redemption. This information is supplied as a convenience to shareholders and will not be reported to the IRS. Although the IRS permits the use of several methods to determine the cost basis of mutual fund shares, the cost basis information provided by the Transfer Agent will be calculated using only the single-category average cost method. Neither the Transfer Agent nor the Fund recommends any particular method of determining cost basis, and the use of other methods may result in more favorable tax consequences for some shareholders. Even if you have reported gains or losses for a Fund in past years using another

74

method of basis determination, you may be able to use the average cost method for determining gains or losses in the current year. However, once you have elected to use the average cost method, you must continue to use it unless you apply to the IRS for permission to change methods.

If a shareholder (a) incurs a sales load in acquiring shares of a Fund, (b) disposes of such shares less than 91 days after they are acquired, and (c) subsequently acquires shares of the Fund or another fund at a reduced sales load pursuant to a right to reinvest at such reduced sales load acquired in connection with the acquisition of the shares disposed of, then the sales load on the shares disposed of (to the extent of the reduction in the sales load on the shares subsequently acquired) shall not be taken into account in determining gain or loss on the shares disposed of, but shall be treated as incurred on the acquisition of the shares subsequently acquired. The wash sale rules may also limit the amount of loss that may be taken into account on disposition after such adjustment.

The automatic conversion of Class B shares into Class A shares of the same Fund at the end of approximately eight years after purchase will be tax-free for federal income tax purposes. Shareholders should consult their tax advisers regarding the state and local tax consequences of such conversion.

BACKUP WITHHOLDING. The Funds may be required to withhold 28% of distributions and/or redemption payments. For more information refer to "Purchase, Redemption and Pricing of Shares - Backup Withholding".

FOREIGN SHAREHOLDERS. Shareholders who, as to the United States, are a non-resident alien individual, foreign trust or estate, foreign corporation, or foreign partnership ("foreign shareholder"), may be subject to U.S. withholding and estate tax and are subject to special U.S. tax certification requirements. Foreign shareholders should consult their tax advisors about the applicability of U.S. tax withholding and the use of the appropriate forms to certify their status.

Taxation of a foreign shareholder depends on whether the income from a Fund is "effectively connected" with a U.S. trade or business carried on by such shareholder. If the income from a Fund is not effectively connected with a U.S. trade or business carried on by a foreign shareholder, distributions to such shareholder (other than certain capital gain dividends and exempt-interest dividends) will be subject to U.S. withholding tax at the rate of 30% (or lower treaty rate) upon the gross amount of the distribution. Such a foreign shareholder would generally be exempt from U.S. federal income tax on gains realized on the redemption of shares of a Fund, capital gain dividends, exempt-interest dividends and amounts retained by a Fund that are designated as undistributed net capital gains. The exemption for capital gains does not apply if you are a non-resident alien individual present in the United States for a period or periods aggregating 183 days or more during the taxable year.

If the income from a Fund is effectively connected with a U.S. trade or business carried on by a foreign shareholder, then ordinary income dividends, capital gain dividends and any gains realized upon the sale or redemption of shares of the Fund will be subject to U.S. federal income tax at the rates applicable to U.S. citizens or domestic corporations and require the filing of a non-resident U.S. income tax return.

In the case of foreign non-corporate shareholders, a Fund may be required to withhold U.S. federal income tax at a rate of 28% on distributions that are otherwise exempt from withholding tax (or taxable at a reduced treaty rate) unless such shareholders furnish the Fund with proper notification of their foreign status.

Foreign persons who file a United States tax return to obtain a U.S. tax refund and who are not eligible to obtain a social security number must apply to the IRS for an individual taxpayer identification number, using IRS Form W-7. For a copy of the IRS Form W-7 and accompanying instructions, please contact your tax advisor or the IRS.

Transfers by gift of shares of a Fund by a foreign shareholder who is a nonresident alien individual will not be subject to U.S. federal gift tax. An individual who, at the time of death, is a foreign

75

shareholder will nevertheless be subject to U.S. federal estate tax with respect to shares at the graduated rates applicable to U.S. citizens and residents, unless a treaty exception applies. If a treaty exemption is available, a decedent's estate may nonetheless need to file a U.S. estate tax return to claim the exemption in order to obtain a U.S. federal transfer certificate. The transfer certificate will identify the property (i.e., Fund shares) as to which the U.S. federal estate tax lien has been released. In the absence of a treaty, there is a $13,000 statutory estate tax credit. Estates of non-resident alien shareholders dying after December 31, 2004 and before January 1, 2008 will be able to exempt from federal estate tax the proportion of the value of a Fund's shares attributable to "qualifying assets" held by the Fund at the end of the quarter immediately preceding the non-resident alien shareholders' death (or such other time as the IRS may designate in regulations). Qualifying assets include bank deposits and other debt obligations that pay interest or accrue original issue discount that is exempt from withholding tax, debt obligations of a domestic corporation that are treated as giving rise to foreign source income, and other investments that are not treated for tax purposes as being within the United States. Through December 31, 2007, shareholders will be advised annually of the portion of a Fund's assets that constituted qualifying assets at the end of each quarter of its taxable year.

The tax consequences to a foreign shareholder entitled to claim the benefits of an applicable tax treaty may be different from those described herein. Foreign shareholders are urged to consult their own tax advisers with respect to the particular tax consequences to them of an investment in a Fund, including the applicability of foreign tax.

EFFECT OF FUTURE LEGISLATION; LOCAL TAX CONSIDERATIONS. The foregoing general discussion of U.S. federal income tax consequences is based on the Code and the regulations issued thereunder as in effect on the date of this Registration Statement. Future legislative or administrative changes or court decisions may significantly change the conclusions expressed herein, and any such changes or decisions may have a retroactive effect with respect to the transactions contemplated herein.

Rules of state and local taxation of ordinary income, exempt-interest and capital gain dividends differ from the rules for U.S. federal income taxation described above. Distributions may also be subject to additional state, local and foreign taxes depending on each shareholder's particular situation. Non-U.S. shareholders may be subject to U.S. tax rules that differ significantly from those summarized above. Shareholders are urged to consult their tax advisers as to the consequences of these and other state and local tax rules affecting investment in the Funds.

DISTRIBUTION OF SECURITIES

DISTRIBUTION PLANS

The Trust has adopted distribution plans pursuant to Rule 12b-1 under the 1940 Act with respect to Class A shares of AIM High Income Municipal Fund and AIM Tax-Exempt Cash Fund, Class A3 shares of AIM Tax-Free Intermediate Fund and Class B shares and Class C shares of AIM High Income Municipal Fund (collectively the "Plans"). Each Fund, pursuant to the Plans except the Investor Class Plan, pays Invesco Aim Distributors compensation at the annual rate, shown immediately below, of the Fund's average daily net assets of the applicable class.

FUND                             CLASS A   CLASS A3   CLASS B   CLASS C   INVESTOR CLASS
----                             -------   --------   -------   -------   --------------
AIM High Income Municipal Fund    0.25%       N/A      1.00%     1.00%          N/A
AIM Tax-Exempt Cash Fund          0.25%       N/A       N/A       N/A           N/A
AIM Tax-Free Intermediate Fund     N/A       0.25%      N/A       N/A           N/A

76

All of the Plans compensate Invesco Aim Distributors for the purpose of financing any activity which is primarily intended to result in the sale of shares of the Funds. Such activities include, but are not limited to, the following: printing of prospectuses and statements of additional information and reports for other than existing shareholders; overhead; preparation and distribution of advertising material and sales literature; expenses of organizing and conducting sales seminars; supplemental payments to dealers and other institutions such as asset-based sales charges or as payments of service fees under shareholder service arrangements; and costs of administering each Plan.

Amounts payable by a Fund under the Class A, Class A3, Class B and Class C Plans need not be directly related to the expenses actually incurred by Invesco Aim Distributors on behalf of each Fund. These Plans do not obligate the Funds to reimburse Invesco Aim Distributors for the actual allocated share of expenses Invesco Aim Distributors may incur in fulfilling its obligations under these Plans. Thus, even if Invesco Aim Distributors' actual allocated share of expenses exceeds the fee payable to Invesco Aim Distributors at any given time under these Plans, the Funds will not be obligated to pay more than that fee. If Invesco Aim Distributors' actual allocated share of expenses is less than the fee it receives under these Plans, Invesco Aim Distributors will retain the full amount of the fee.

Invesco Aim Distributors may from time to time waive or reduce any portion of its 12b-1 fee for Class A shares, Class A3 shares or Class C shares. Voluntary fee waivers or reductions may be rescinded at any time without further notice to investors. During periods of voluntary fee waivers or reductions, Invesco Aim Distributors will retain its ability to be reimbursed for such fee prior to the end of each fiscal year. Contractual fee waivers or reductions set forth in the Fee Table in a Prospectus may not be terminated or amended to the Funds' detriment during the period stated in the agreement between Invesco Aim Distributors and the Fund.

Invesco Aim Distributors has contractually agreed through June 30, 2009, to waive 0.15% of average net assets of AIM Tax-Exempt Cash Fund Class A shares' Rule 12b-1 distribution plan payments. This contractual fee waiver is set forth in the Fee Table to the Fund's Prospectus and may not be terminated or amended to the Fund's detriment during the period stated in the agreement between Invesco Aim Distributors and the Fund.

The Funds may pay a service fee of 0.25% of the average daily net assets of the Class A, Class A3, Class B and Class C shares to selected dealers and financial institutions, including Invesco Aim Distributors, acting as principal, who furnish continuing personal shareholder services to their customers who purchase and own the applicable class of shares of the Fund. Under the terms of a shareholder service agreement, such personal shareholder services include responding to customer inquiries and providing customers with information about their investments. Any amounts not paid as a service fee under each Plan would constitute an asset-based sales charge.

Under a Shareholder Service Agreement, a Fund agrees to pay periodically fees to selected dealers and other institutions who render the foregoing services to their customers. The fees payable under a Shareholder Service Agreement will be calculated at the end of each payment period for each business day of the Funds during such period at the annual rate specified in each agreement based on the average daily net asset value of the Funds' shares purchased or acquired through exchange. Fees shall be paid only to those selected dealers or other institutions who are dealers or institutions of record at the close of business on the last business day of the applicable payment period for the account in which such Fund's shares are held.

Selected dealers and other institutions entitled to receive compensation for selling Fund shares may receive different compensation for selling shares of one particular class over another. Under the Plans, certain financial institutions which have entered into service agreements and which sell shares of the Funds on an agency basis, may receive payments from the Funds pursuant to the respective Plans. Invesco Aim Distributors does not act as principal, but rather as agent for the Funds, in making dealer incentive and shareholder servicing payments to dealers and other financial institutions under the Plans. These payments are an obligation of the Funds and not of Invesco Aim Distributors.

77

Payments pursuant to the Plans are subject to any applicable limitations imposed by rules of FINRA.

See Appendix M for a list of the amounts paid by each class of shares of each Fund to Invesco Aim Distributors pursuant to the Plans for the year, or period, ended March 31, 2008 and Appendix N for an estimate by category of the allocation of actual fees paid by each class of shares of each Fund pursuant to its respective distribution plan for the year or period ended March 31, 2008.

As required by Rule 12b-1, the Plans and related forms of Shareholder Service Agreements were approved by the Board of Trustees, including a majority of the trustees who are not "interested persons" (as defined in the 1940 Act) of the Trust and who have no direct or indirect financial interest in the operation of the Plans or in any agreements related to the Plans (the "Rule 12b-1 Trustees"). In approving the Plans in accordance with the requirements of Rule 12b-1, the trustees considered various factors and determined that there is a reasonable likelihood that the Plans would benefit each class of the Funds and its respective shareholders.

The anticipated benefits that may result from the Plans with respect to each Fund and/or the classes of each Fund and its shareholders include but are not limited to the following: (1) rapid account access; (2) relatively predictable flow of cash; and (3) a well-developed, dependable network of shareholder service agents to help to curb sharp fluctuations in rates of redemptions and sales, thereby reducing the chance that an unanticipated increase in net redemptions could adversely affect the performance of each Fund.

Unless terminated earlier in accordance with their terms, the Plans continue from year to year as long as such continuance is specifically approved, in person, at least annually by the Board, including a majority of the Rule 12b-1 Trustees. A Plan may be terminated as to any Fund or class by the vote of a majority of the Rule 12b-1 Trustees or, with respect to a particular class, by the vote of a majority of the outstanding voting securities of that class.

Any change in the Plans that would increase materially the distribution expenses paid by the applicable class requires shareholder approval; otherwise, the Plans may be amended by the trustees, including a majority of the Rule 12b-1 Trustees, by votes cast in person at a meeting called for the purpose of voting upon such amendment. As long as the Plans are in effect, the selection or nomination of the Independent Trustees is committed to the discretion of the Independent Trustees.

The Class B Plan obligates Class B shares to continue to make payments to Invesco Aim Distributors following termination of the Class B shares Distribution Agreement with respect to Class B shares sold by or attributable to the distribution efforts of Invesco Aim Distributors, unless there has been a complete termination of the Class B Plan (as defined in such Plan) and the Class B Plan expressly authorizes Invesco Aim Distributors to assign, transfer or pledge its rights to payments pursuant to the Class B Plan.

DISTRIBUTOR

The Trust has entered into master distribution agreements, as amended, relating to the Funds (the "Distribution Agreements") with Invesco Aim Distributors, a registered broker-dealer and a wholly owned subsidiary of Invesco Aim, pursuant to which Invesco Aim Distributors acts as the distributor of shares of the Funds. The address of Invesco Aim Distributors is P.O. Box 4739, Houston, Texas 77210-4739. Certain trustees and officers of the Trust are affiliated with Invesco Aim Distributors. See "Management of the Trust."

The Distribution Agreements provide Invesco Aim Distributors with the exclusive right to distribute shares of the Funds on a continuous basis directly and through other broker dealers and with whom Invesco Aim Distributors has entered into selected dealer agreements. Invesco Aim Distributors has not undertaken to sell any specified number of shares of any classes of the Funds.

78

Invesco Aim Distributors expects to pay sales commissions from its own resources to dealers and institutions who sell Class B and Class C shares of AIM High Income Municipal Fund at the time of such sales.

Payments with respect to Class B shares will equal 4.00% of the purchase price of the Class B shares sold by the dealer or institution, and will consist of a sales commission equal to 3.75% of the purchase price of the Class B shares sold plus an advance of the first year service fee of 0.25% with respect to such shares. The portion of the payments to Invesco Aim Distributors under the Class B Plan which constitutes an asset-based sales charge (0.75%) is intended in part to permit Invesco Aim Distributors to recoup a portion of such sales commissions plus financing costs. In the future, if multiple distributors serve AIM High Income Municipal Fund, each such distributor (or its assignee or transferee) would receive a share of the payments under the Class B Plan based on the portion of AIM High Income Municipal Fund's Class B shares sold by or attributable to the distribution efforts of that distributor.

Invesco Aim Distributors may pay sales commissions to dealers and institutions who sell Class C shares of AIM High Income Municipal Fund at the time of such sales. Payments with respect to Class C shares will equal 1.00% of the purchase price of the Class C shares sold by the dealer or institution, and will consist of a sales commission of 0.75% of the purchase price of the Class C shares sold plus an advance of the first year service fee of 0.25% with respect to such shares. Invesco Aim Distributors will retain all payments received by it relating to Class C shares for the first year after they are purchased. The portion of the payments to Invesco Aim Distributors under the Class C Plan which constitutes an asset-based sales charge (0.75%) is intended in part to permit Invesco Aim Distributors to recoup a portion of the sales commissions to dealers plus financing costs, if any. After the first full year, Invesco Aim Distributors will make quarterly payments to dealers and institutions based on the average net asset value of Class C shares which are attributable to shareholders for whom the dealers and institutions are designated as dealers of record. These payments will consist of an asset-based sales charge of 0.75% and a service fee of 0.25%.

The Trust (on behalf of any class of any Fund) or Invesco Aim Distributors may terminate the Distribution Agreements on 60 days' written notice without penalty. The Distribution Agreements will terminate automatically in the event of their assignment. In the event the Class B shares Distribution Agreement is terminated, Invesco Aim Distributors would continue to receive payments of asset-based distribution fees in respect of the outstanding Class B shares attributable to the distribution efforts of Invesco Aim Distributors or its predecessors; provided, however that a complete termination of the Class B Plan (as defined in such Plan) would terminate all payments to Invesco Aim Distributors. Termination of the Class B Plan or the Distribution Agreement for Class B shares would not affect the obligation of AIM High Income Municipal Fund and its Class B shareholders to pay contingent deferred sales charges.

Total sales charges (front end and contingent deferred sales charges) paid in connection with the sale of shares of each Fund, if applicable, for the last three fiscal years ended March 31 are found in Appendix O.

PENDING LITIGATION

Settled Enforcement Actions Related to Market Timing

On October 8, 2004, INVESCO Funds Group, Inc. ("IFG") (the former investment advisor to certain AIM Funds), Invesco Aim and Invesco Aim Distributors reached final settlements with certain regulators, including the SEC, the New York Attorney General and the Colorado Attorney General, to resolve civil enforcement actions and/or investigations related to market timing and related activity in the AIM Funds, including those formerly advised by IFG. As part of the settlements, a $325 million fair fund ($110 million of which is civil penalties) has been created to compensate shareholders harmed by market timing and related activity in funds formerly advised by IFG. Additionally, Invesco Aim and Invesco Aim Distributors created a $50 million fair fund ($30 million of which is civil penalties) to compensate shareholders harmed by market timing and related activity in funds advised by Invesco Aim, which was done pursuant to the terms of the settlements. These two fair funds will be distributed in accordance with a methodology to be determined by Invesco Aim's independent distribution consultant ("IDC Plan"), in consultation with Invesco Aim and the independent trustees of the AIM Funds and approved by the staff of the SEC. Further details regarding the IDC Plan and planned distributions thereunder are available under the "About Us-SEC Settlement" section of Invesco Aim's website, at http://www.invescoaim.com. Invesco Aim's website is not a part of this Statement of Additional Information or the prospectus of any AIM Fund.

Regulatory Action Alleging Market Timing

On August 30, 2005, the West Virginia Office of the State Auditor - Securities Commission ("WVASC") issued a Summary Order to Cease and Desist and Notice of Right to Hearing to Invesco Aim and ADI (Order No. 05-1318). The WVASC makes findings of fact that Invesco Aim and Invesco Aim Distributors entered into certain arrangements permitting market timing of the AIM Funds and failed to disclose these arrangements in the prospectuses for such Funds, and conclusions of law to the effect that Invesco Aim and Invesco Aim Distributors violated the West Virginia securities laws. The WVASC orders Invesco Aim and Invesco Aim Distributors to cease any further violations and seeks to impose monetary sanctions, including restitution to affected investors, disgorgement of fees, reimbursement of investigatory, administrative and legal costs and an "administrative assessment," to be determined by the Commissioner. Initial research indicates that these damages could be limited or capped by statute. By agreement with the Commissioner of Securities, Invesco Aim's time to respond to that Order has been indefinitely suspended.

Private Civil Actions Alleging Market Timing

Multiple civil lawsuits, including purported class action and shareholder derivative suits, have been filed against various parties (including, depending on the lawsuit, certain AIM Funds, IFG, Invesco Aim, Invesco Aim Management and certain related entities, certain of their current and former officers and/or certain unrelated third parties) based on allegations of improper market timing and related activity in the AIM Funds. These lawsuits allege a variety of theories of recovery, including but not limited to: (i) violation of various provisions of the Federal and state securities laws; (ii) violation of various provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"); (iii) breach of fiduciary duty; and/or (iv) breach of contract. These lawsuits were initiated in both Federal and state courts and seek such remedies as compensatory damages; restitution; injunctive relief; disgorgement of management fees; imposition of a constructive trust; removal of certain directors and/or employees; various corrective measures under ERISA; rescission of certain Funds' advisory agreements; interest; and attorneys' and experts' fees. A list identifying such lawsuits (excluding those lawsuits that have been recently transferred as mentioned herein) that have been served on IFG, Invesco Aim, the AIM Funds or related entities, or for which service of process has been waived is set forth in Appendix P-1.

All lawsuits based on allegations of market timing, late trading, and related issues have been transferred to the United States District Court for the District of Maryland (the "MDL Court") for consolidated or coordinated pre-trial proceedings. Pursuant to an Order of the MDL Court, plaintiffs in

80

these lawsuits consolidated their claims for pre-trial purposes into three amended complaints against various Invesco Aim- and IFG-related parties. A list identifying the amended complaints in the MDL Court is included in Appendix P-1. Plaintiffs in two of the underlying lawsuits transferred to the MDL Court continue to seek remand of their action to state court. These lawsuits are identified in Appendix P-1.

Private Civil Actions Alleging Improper Use of Fair Value Pricing

Multiple civil class action lawsuits have been filed against various parties (including, depending on the lawsuit, certain AIM Funds, IFG and/or Invesco Aim) alleging that certain AIM Funds inadequately employed fair value pricing. These lawsuits allege a variety of theories of recovery, including but not limited to: (i) violations of various provisions of the Federal securities laws; (ii) common law breach of duty; and (iii) common law negligence and gross negligence. These lawsuits have been filed in both Federal and state courts and seek such remedies as compensatory and punitive damages; interest; and attorneys' fees and costs. A list identifying such lawsuits that have been served on IFG, Invesco Aim, the AIM Funds or related entities, or for which service of process has been waived is set forth in Appendix P-2.

APPENDIX A

RATINGS OF DEBT SECURITIES

The following is a description of the factors underlying the debt ratings of Moody's, S&P and Fitch.

MOODY'S LONG-TERM DEBT RATINGS

AAA: Obligations rated Aaa are judged to be of the highest quality, with minimal credit risk.

AA: Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.

A: Obligations rated A are considered upper-medium grade and are subject to low credit risk.

BAA; Obligations rated Baa are subject to moderate credit risk. They are considered medium-grade and as such may possess certain speculative characteristics.

BA: Obligations rated Ba are judged to have speculative elements and are subject to substantial credit risk.

B: Obligations rated B are considered speculative and are subject to high credit risk.

CAA: Obligations rated Caa are judged to be of poor standing and are subject to very high credit risk.

CA: Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.

C: Obligations rated C are the lowest rated class of bonds and are typically in default, with little prospect for recovery of principal or interest.

Note: Moody's applies numerical modifiers 1, 2, and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category.

MOODY'S SHORT-TERM PRIME RATING SYSTEM

P-1

Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.

P-2

Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.

P-3

Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.

Not Prime

Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

A-1

Note: In addition, in certain countries the prime rating may be modified by the issuer's or guarantor's senior unsecured long-term debt rating.

Moody's municipal ratings are as follows:

MOODY'S U.S. LONG-TERM MUNICIPAL BOND RATING DEFINITIONS

Municipal Ratings are opinions of the investment quality of issuers and issues in the US municipal and tax-exempt markets. As such, these ratings incorporate Moody's assessment of the default probability and loss severity of these issuers and issues.

Municipal Ratings are based upon the analysis of four primary factors relating to municipal finance: economy, debt, finances, and administration/management strategies. Each of the factors is evaluated individually and for its effect on the other factors in the context of the municipality's ability to repay its debt.

AAA: Issuers or issues rated Aaa demonstrate the strongest creditworthiness relative to other US municipal or tax-exempt issuers or issues.

AA: Issuers or issues rated Aa demonstrate very strong creditworthiness relative to other US municipal or tax-exempt issuers or issues.

A: Issuers or issues rated A present above-average creditworthiness relative to other US municipal or tax-exempt issuers or issues.

BAA: Issuers or issues rated Baa represent average creditworthiness relative to other US municipal or tax-exempt issuers or issues.

BA: Issuers or issues rated Ba demonstrate below-average creditworthiness relative to other US municipal or tax-exempt issuers or issues.

B: Issuers or issues rated B demonstrate weak creditworthiness relative to other US municipal or tax-exempt issuers or issues.

CAA: Issuers or issues rated Caa demonstrate very weak creditworthiness relative to other US municipal or tax-exempt issuers or issues.

CA: Issuers or issues rated Ca demonstrate extremely weak creditworthiness relative to other US municipal or tax-exempt issuers or issues.

C: Issuers or issues rated C demonstrate the weakest creditworthiness relative to other US municipal or tax-exempt issuers or issues.

Note: Also, Moody's applied numerical modifiers 1, 2, and 3 in each generic rating classification from Aa to Caa. The modifier 1 indicates that the issue ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks in the lower end of its generic category.

MOODY'S MIG/VMIG US SHORT-TERM RATINGS

In municipal debt issuance, there are three rating categories for short-term obligations that are considered investment grade. These ratings are designated as Moody's Investment Grade (MIG) and are divided into three levels - MIG 1 through MIG 3.

In addition, those short-term obligations that are of speculative quality are designated SG, or speculative grade.

A-2

In the case of variable rate demand obligations (VRDOs), a two-component rating is assigned. The first element represents Moody's evaluation of the degree of risk associated with scheduled principal and interest payments. The second element represents Moody's evaluation of the degree of risk associated with the demand feature, using the MIG rating scale.

The short-term rating assigned to the demand feature of VRDOs is designated as VMIG. When either the long- or short-term aspect of a VRDO is not rated, that piece is designated NR, e.g., Aaa/NR or NR/VMIG 1.

MIG ratings expire at note maturity. By contrast, VMIG rating expirations will be a function of each issue's specific structural or credit features.

Gradations of investment quality are indicated by rating symbols, with each symbol representing a group in which the quality characteristics are broadly the same.

MIG 1/VMIG 1: This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support or demonstrated broad-based access to the market for refinancing.

MIG 2/VMIG 2: This designation denotes strong credit quality. Margins of protection are ample although not as large as in the preceding group.

MIG 3/VMIG 3: This designation denotes acceptable credit quality. Liquidity and cash flow protection may be narrow and market access for refinancing is likely to be less well established.

SG: This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

STANDARD & POOR'S LONG-TERM CORPORATE AND MUNICIPAL RATINGS

Issue credit ratings are based in varying degrees, on the following considerations: likelihood of payment - capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation; nature of and provisions of the obligation; and protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors' rights.

The issue ratings definitions are expressed in terms of default risk. As such, they pertain to senior obligations of an entity. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy, as noted above.

S&P describes its ratings for corporate and municipal bonds as follows:

AAA: Debt rated AAA has the highest rating assigned by S&P. Capacity to pay interest and repay principal is extremely strong.

AA: Debt rated AA has a very strong capacity to pay interest and repay principal and differs from the highest rated issues only in a small degree.

A: Debt rated A has a strong capacity to meet its financial commitments although it is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher rated categories.

BBB: Debt rated BBB exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to meet its financial commitment on the obligation.

A-3

BB-B-CCC-CC-C: Debt rated BB, B, CCC, CC and C is regarded as having significant speculative characteristics with respect to capacity to pay interest and repay principal. BB indicates the least degree of speculation and C the highest. While such debt will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

NR: Not Rated.

S&P DUAL RATINGS

S&P assigns "dual" ratings to all debt issues that have a put option or demand feature as part of their structure.

The first rating addresses the likelihood of repayment of principal and interest as due, and the second rating addresses only the demand feature. The long-term debt rating symbols are used for bonds to denote the long-term maturity and the commercial paper rating symbols for the put option (for example, AAA/A-1+). With short-term demand debt, the not rating symbols are used with the commercial paper rating symbols (for example, SP-1+/A-1+).

S&P COMMERCIAL PAPER RATINGS

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

These categories are as follows:

A-1: This highest category indicates that the degree of safety regarding timely payment is strong. Those issues determined to possess extremely strong safety characteristics are denoted with a plus sign (+) designation.

A-2: Capacity for timely payment on issues with this designation is satisfactory. However, the relative degree of safety is not as high as for issues designated A-1.

A-3: Issues carrying this designation have adequate capacity for timely payment. They are, however, more vulnerable to the adverse effects of changes in circumstances than obligations carrying the higher designations.

B: Issues rated "B" are regarded as having only speculative capacity for timely payment.

C: This rating is assigned to short-term debt obligations with a doubtful capacity for payment.

D: Debt rated "D" is in payment default. The "D" rating category is used when interest payments or principal payments are not made on the date due, even if the applicable grace period has not expired, unless Standard & Poor's believes such payments will be made during such grace period.

S&P SHORT-TERM MUNICIPAL RATINGS

An S&P note rating reflect the liquidity factors and market-access risks unique to notes. Notes due in three years or less will likely receive a note rating. Notes maturing beyond three years will most likely receive a long-term debt rating. The following criteria will be used in making that assessment:
amortization schedule (the larger the final maturity relative to other maturities, the more likely it will be treated as a note); and source of payment (the more dependent the issue is on the market for its refinancing, the more likely it will be treated as a note).

A-4

Note rating symbols are as follows:

SP-1: Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.

SP-2: Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

SP-3: Speculative capacity to pay principal and interest.

FITCH LONG-TERM CREDIT RATINGS

Fitch Ratings provides an opinion on the ability of an entity or of a securities issue to meet financial commitments, such as interest, preferred dividends, or repayment of principal, on a timely basis. These credit ratings apply to a variety of entities and issues, including but not limited to sovereigns, governments, structured financings, and corporations; debt, preferred/preference stock, bank loans, and counterparties; as well as the financial strength of insurance companies and financial guarantors.

Credit ratings are used by investors as indications of the likelihood of getting their money back in accordance with the terms on which they invested. Thus, the use of credit ratings defines their function: "investment grade" ratings (international Long-term "AAA" - "BBB" categories; Short-term "F1" - "F3") indicate a relatively low probability of default, while those in the "speculative" or "non-investment grade" categories (international Long-term "BB"
- "D"; Short-term "B" - "D") either signal a higher probability of default or that a default has already occurred. Ratings imply no specific prediction of default probability. However, for example, it is relevant to note that over the long term, defaults on "AAA" rated U.S. corporate bonds have averaged less than 0.10% per annum, while the equivalent rate for "BBB" rated bonds was 0.35%, and for "B" rated bonds, 3.0%.

Fitch ratings do not reflect any credit enhancement that may be provided by insurance policies or financial guaranties unless otherwise indicated.

Entities or issues carrying the same rating are of similar but not necessarily identical credit quality since the rating categories do not fully reflect small differences in the degrees of credit risk.

Fitch credit and research are not recommendations to buy, sell or hold any security. Ratings do not comment on the adequacy of market price, the suitability of any security for a particular investor, or the tax-exempt nature of taxability of payments of any security.

The ratings are based on information obtained from issuers, other obligors, underwriters, their experts, and other sources Fitch Ratings believes to be reliable. Fitch Ratings does not audit or verify the truth or accuracy of such information. Ratings may be changed or withdrawn as a result of changes in, or the unavailability of, information or for other reasons.

Our program ratings relate only to standard issues made under the program concerned; it should not be assumed that these ratings apply to every issue made under the program. In particular, in the case of non-standard issues, i.e., those that are linked to the credit of a third party or linked to the performance of an index, ratings of these issues may deviate from the applicable program rating.

Credit ratings do not directly address any risk other than credit risk. In particular, these ratings do not deal with the risk of loss due to changes in market interest rates and other market considerations.

AAA: Bonds considered to be investment grade and of the highest credit quality. The obligor has an exceptionally strong capacity for timely payment of financial commitments, which is unlikely to be affected by foreseeable events.

A-5

AA: Bonds considered to be investment grade and of very high credit quality. The obligor has a very strong capacity for timely payment of financial commitments which is not significantly vulnerable to foreseeable events.

A: Bonds considered to be investment grade and of high credit quality. The obligor's ability to pay interest and repay principal is considered to be strong, but may be more vulnerable to adverse changes in economic conditions and circumstances than bonds with higher ratings.

BBB: Bonds considered to be investment grade and of good credit quality. The obligor's ability to pay interest and repay principal is considered to be adequate. Adverse changes in economic conditions and circumstances are more likely to impair this capacity.

PLUS (+) MINUS (-): Plus and minus signs are used with a rating symbol to indicate the relative position of a credit within the rating category. Plus and minus signs, however, are not used in the "AAA" category.

NR: Indicates that Fitch does not rate the specific issue.

WITHDRAWN: A rating will be withdrawn when an issue matures or is called or refinanced and at Fitch's discretion, when Fitch Ratings deems the amount of information available to be inadequate for ratings purposes.

RATINGWATCH: Ratings are placed on RatingWatch to notify investors that there is a reasonable possibility of a rating change and the likely direction of such change. These are designated as "Positive," indicating a potential upgrade, "Negative," for potential downgrade, or "Evolving," if ratings may be raised, lowered or maintained. RatingWatch is typically resolved over a relatively short period.

FITCH SPECULATIVE GRADE BOND RATINGS

BB: Bonds are considered speculative. There is a possibility of credit risk developing, particularly as the result of adverse economic changes over time. However, business and financial alternatives may be available to allow financial commitments to be met.

B: Bonds are considered highly speculative. Significant credit risk is present but a limited margin of safety remains. While bonds in this class are currently meeting financial commitments, the capacity for continued payment is contingent upon a sustained, favorable business and economic environment.

CCC: Default is a real possibility. Capacity for meeting financial commitments is solely reliant upon sustained, favorable business or economic developments.

CC: Default of some kind appears probable.

C: Bonds are in imminent default in payment of interest or principal.

DDD, DD, AND D: Bonds are in default on interest and/or principal payments. Such bonds are extremely speculative and are valued on the basis of their prospects for achieving partial or full recovery value in liquidation or reorganization of the obligor. "DDD" represents the highest potential for recovery on these bonds, and "D" represents the lowest potential for recovery.

PLUS (+) MINUS (-): Plus and minus signs are used with a rating symbol to indicate the relative position of a credit within the rating category. Plus and minus signs, however, are not used in categories below CCC.

A-6

FITCH SHORT-TERM CREDIT RATINGS

The following ratings scale applies to foreign currency and local currency ratings. A Short-term rating has a time horizon of less than 12 months for most obligations, or up to three years for U.S. public finance securities, and thus places greater emphasis on the liquidity necessary to meet financial commitments in a timely manner.

F-1+: Exceptionally Strong Credit Quality. Issues assigned this rating are regarded as having the strongest degree of assurance for timely payment.

F-1-: Very Strong Credit Quality. Issues assigned this rating reflect an assurance of timely payment only slightly less in degree than issues rated "F-1+;"

F-2: Good Credit Quality. Issues assigned this rating have a satisfactory degree of assurance for timely payment, but the margin of safety is not as great as in the case of the higher ratings.

F-3: Fair Credit Quality. Issues assigned this rating have characteristics suggesting that the degree of assurance for timely payment is adequate, however, near-term adverse changes could result in a reduction to non-investment grade.

B: Speculative. Minimal capacity for timely payment of financial commitments, plus vulnerability to near-term adverse changes in financial and economic conditions.

C: High default risk. Default is a real possibility. Capacity for meeting financial commitments is solely reliant upon a sustained, favorable business and economic environment.

D: Default. Issues assigned this rating are in actual or imminent payment default.

The following Invesco Aim Proxy Voting Guidelines are applicable to all funds and other accounts managed by Invesco Aim Advisors, Inc., Invesco Aim Capital Management, Inc and Invesco Aim Private Asset Management, Inc. (collectively, "Invesco Aim").(1)

INTRODUCTION

OUR BELIEF

The AIM Funds Boards of Trustees and Invesco Aim's investment professionals expect a high standard of corporate governance from the companies in our portfolios so that Invesco Aim may fulfill its fiduciary obligation to our fund shareholders and other account holders. Well governed companies are characterized by a primary focus on the interests of shareholders, accountable boards of directors, ample transparency in financial disclosure, performance-driven cultures and appropriate consideration of all stakeholders. Invesco Aim believes well governed companies create greater shareholder wealth over the long term than poorly governed companies, so we endeavor to vote in a manner that increases the value of our investments and fosters good governance within our portfolio companies.

In determining how to vote proxy issues, Invesco Aim considers the probable business consequences of each issue and votes in a manner designed to protect and enhance fund shareholders' and other account holders' interests. Our voting decisions are intended to enhance each company's total shareholder value over Invesco Aim's typical investment horizon.

Proxy voting is an integral part of Invesco Aim's investment process. We believe that the right to vote proxies should be managed with the same care as all other elements of the investment process. The objective of Invesco Aim's proxy-voting activity is to promote good governance and advance the economic interests of our clients. At no time will Invesco Aim exercise its voting power to advance its own commercial interests, to pursue a social or political cause that is unrelated to our clients' economic interests, or to favor a particular client or business relationship to the detriment of others.

PROXY ADMINISTRATION

The Invesco Aim Proxy Committee (the "Proxy Committee") consists of members representing Invesco Aim's Investments, Legal and Compliance departments. Invesco Aim's Proxy Voting Guidelines (the "Guidelines") are revised annually by the Proxy Committee, and are approved by the AIM Funds Boards of Trustees. The Proxy Committee implements the Guidelines and oversees proxy voting.

The Proxy Committee has retained outside experts to assist with the analysis and voting of proxy issues. In addition to the advice offered by these experts, Invesco Aim uses information gathered from our own research, company managements, Invesco Aim's portfolio managers and outside shareholder groups to reach our voting decisions.

E-1

Generally speaking, Invesco Aim's investment-research process leads us to invest in companies led by management teams we believe have the ability to conceive and execute strategies to outperform their competitors. We select companies for investment based in large part on our assessment of their management teams' ability to create shareholder wealth. Therefore, in formulating our proxy-voting decisions, Invesco Aim gives proper consideration to the recommendations of a company's Board of Directors.

IMPORTANT PRINCIPLES UNDERLYING THE INVESCO AIM PROXY VOTING GUIDELINES

I. ACCOUNTABILITY

Management teams of companies are accountable to their boards of directors, and directors of publicly held companies are accountable to their shareholders. Invesco Aim endeavors to vote the proxies of its portfolio companies in a manner that will reinforce the notion of a board's accountability to its shareholders. Consequently, Invesco Aim votes against any actions that would impair the rights of shareholders or would reduce shareholders' influence over the board or over management.

The following are specific voting issues that illustrate how Invesco Aim applies this principle of accountability.

- Elections of directors. In uncontested director elections for companies that do not have a controlling shareholder, Invesco Aim votes in favor of slates if they are comprised of at least a majority of independent directors and if the boards' key committees are fully independent. Key committees include the Audit, Compensation and Governance or Nominating Committees. Invesco Aim's standard of independence excludes directors who, in addition to the directorship, have any material business or family relationships with the companies they serve.

Contested director elections are evaluated on a case-by-case basis and are decided within the context of Invesco Aim's investment thesis on a company.

- Director performance. Invesco Aim withholds votes from directors who exhibit a lack of accountability to shareholders, either through their level of attendance at meetings or by enacting egregious corporate-governance or other policies. In cases of material financial restatements, accounting fraud, habitually late filings, adopting shareholder rights plan ("poison pills") without shareholder approval, or other areas of poor performance, Invesco Aim may withhold votes from some or all of a company's directors. In situations where directors' performance is a concern, Invesco Aim may also support shareholder proposals to take corrective actions such as so-called "clawback" provisions.

- Auditors and Audit Committee members. Invesco Aim believes a company's Audit Committee has a high degree of responsibility to shareholders in matters of financial disclosure, integrity of the financial statements and effectiveness of a company's internal controls. Independence, experience and financial expertise are critical elements of a well-functioning Audit Committee. When electing directors who are members of a company's Audit Committee, or when ratifying a company's auditors, Invesco Aim considers the past performance of the Committee and holds its members accountable for the quality of the company's financial statements and reports.

- Majority standard in director elections. The right to elect directors is the single most important mechanism shareholders have to promote accountability. Invesco Aim supports the nascent effort to reform the U.S. convention of electing directors, and votes in favor of proposals to elect directors by a majority vote.

- Classified boards. Invesco Aim supports proposals to elect directors annually instead of electing them to staggered multi-year terms because annual elections increase a board's level of accountability to its shareholders.

E-2

- Supermajority voting requirements. Unless proscribed by law in the state of incorporation, Invesco Aim votes against actions that would impose any supermajority voting requirement, and supports actions to dismantle existing supermajority requirements.

- Responsiveness. Invesco Aim withholds votes from directors who do not adequately respond to shareholder proposals that were approved by a majority of votes cast the prior year.

- Cumulative voting. The practice of cumulative voting can enable minority shareholders to have representation on a company's board. Invesco Aim supports proposals to institute the practice of cumulative voting at companies whose overall corporate-governance standards indicate a particular need to protect the interests of minority shareholders.

- Shareholder access. On business matters with potential financial consequences, Invesco Aim votes in favor of proposals that would increase shareholders' opportunities to express their views to boards of directors, proposals that would lower barriers to shareholder action and proposals to promote the adoption of generally accepted best practices in corporate governance.

II. INCENTIVES

Invesco Aim believes properly constructed compensation plans that include equity ownership are effective in creating incentives that induce managements and employees of our portfolio companies to create greater shareholder wealth. Invesco Aim supports equity compensation plans that promote the proper alignment of incentives, and votes against plans that are overly dilutive to existing shareholders, plans that contain objectionable structural features, and plans that appear likely to reduce the value of an account's investment.

Following are specific voting issues that illustrate how Invesco Aim evaluates incentive plans.

- Executive compensation. Invesco Aim evaluates compensation plans for executives within the context of the company's performance under the executives' tenure. Invesco Aim believes independent compensation committees are best positioned to craft executive-compensation plans that are suitable for their company-specific circumstances. We view the election of those independent compensation committee members as the appropriate mechanism for shareholders to express their approval or disapproval of a company's compensation practices. Therefore, Invesco Aim generally does not support shareholder proposals to limit or eliminate certain forms of executive compensation. In the interest of reinforcing the notion of a compensation committee's accountability to shareholders, Invesco Aim supports proposals requesting that companies subject each year's compensation record to an advisory shareholder vote, or so-called "say on pay" proposals.

- Equity-based compensation plans. When voting to approve or reject equity-based compensation plans, Invesco Aim compares the total estimated cost of the plans, including stock options and restricted stock, against a carefully selected peer group and uses multiple performance metrics that help us determine whether the incentive structures in place are creating genuine shareholder wealth. Regardless of a plan's estimated cost relative to its peer group, Invesco Aim votes against plans that contain structural features that would impair the alignment of incentives between shareholders and management. Such features include the ability to reprice or reload options without shareholder approval, the ability to issue options below the stock's current market price, or the ability to automatically replenish shares without shareholder approval.

- Employee stock-purchase plans. Invesco Aim supports employee stock-purchase plans that are reasonably designed to provide proper incentives to a broad base of employees, provided that the price at which employees may acquire stock is at most a 15 percent discount from the market price.

E-3

- Severance agreements. Invesco Aim generally votes in favor of proposals requiring advisory shareholder ratification of executives' severance agreements. However, we oppose proposals requiring such agreements to be ratified by shareholders in advance of their adoption.

III. CAPITALIZATION

Examples of management proposals related to a company's capital structure include authorizing or issuing additional equity capital, repurchasing outstanding stock, or enacting a stock split or reverse stock split. On requests for additional capital stock, Invesco Aim analyzes the company's stated reasons for the request. Except where the request could adversely affect the fund's ownership stake or voting rights, AIM generally supports a board's decisions on its needs for additional capital stock. Some capitalization proposals require a case-by-case analysis within the context of Invesco Aim's investment thesis on a company. Examples of such proposals include authorizing common or preferred stock with special voting rights, or issuing additional stock in connection with an acquisition.

IV. MERGERS, ACQUISITIONS AND OTHER CORPORATE ACTIONS

Issuers occasionally require shareholder approval to engage in certain corporate actions such as mergers, acquisitions, name changes, dissolutions, reorganizations, divestitures and reincorporations. Invesco Aim analyzes these proposals within the context of our investment thesis on the company, and determines its vote on a case-by-case basis.

V. ANTI-TAKEOVER MEASURES

Practices designed to protect a company from unsolicited bids can adversely affect shareholder value and voting rights, and they create conflicts of interests among directors, management and shareholders. Except under special issuer-specific circumstances, Invesco Aim votes to reduce or eliminate such measures. These measures include adopting or renewing "poison pills", requiring supermajority voting on certain corporate actions, classifying the election of directors instead of electing each director to an annual term, or creating separate classes of common or preferred stock with special voting rights. Invesco Aim generally votes against management proposals to impose these types of measures, and generally votes for shareholder proposals designed to reduce such measures. Invesco Aim supports shareholder proposals directing companies to subject their anti-takeover provisions to a shareholder vote.

VI. SHAREHOLDER PROPOSALS ON CORPORATE GOVERNANCE

Invesco Aim generally votes for shareholder proposals that are designed to protect shareholder rights if a company's corporate-governance standards indicate that such additional protections are warranted.

VII. SHAREHOLDER PROPOSALS ON SOCIAL RESPONSIBILITY

The potential costs and economic benefits of shareholder proposals seeking to amend a company's practices for social reasons are difficult to assess. Analyzing the costs and economic benefits of these proposals is highly subjective and does not fit readily within our framework of voting to create greater shareholder wealth over Invesco Aim's typical investment horizon. Therefore, Invesco Aim abstains from voting on shareholder proposals deemed to be of a purely social, political or moral nature.

E-4

VIII. ROUTINE BUSINESS MATTERS

Routine business matters rarely have a potentially material effect on the economic prospects of fund holdings, so we generally support the board's discretion on these items. However, Invesco Aim votes against proposals where there is insufficient information to make a decision about the nature of the proposal. Similarly, Invesco Aim votes against proposals to conduct other unidentified business at shareholder meetings.

SUMMARY

These Guidelines provide an important framework for making proxy-voting decisions, and should give fund shareholders and other account holders insight into the factors driving Invesco Aim's decisions. The Guidelines cannot address all potential proxy issues, however. Decisions on specific issues must be made within the context of these Guidelines and within the context of the investment thesis of the funds and other accounts that own the company's stock. Where a different investment thesis is held by portfolio managers who may hold stocks in common, Invesco Aim may vote the shares held on a fund-by-fund or account-by-account basis.

EXCEPTIONS

In certain circumstances, Invesco Aim may refrain from voting where the economic cost of voting a company's proxy exceeds any anticipated benefits of that proxy proposal.

SHARE-LENDING PROGRAMS

One reason that some portion of Invesco Aim's position in a particular security might not be voted is the securities lending program. When securities are out on loan and earning fees for the lending fund, they are transferred into the borrower's name. Any proxies during the period of the loan are voted by the borrower. The lending fund would have to terminate the loan to vote the company's proxy, an action that is not generally in the best economic interest of fund shareholders. However, whenever Invesco Aim determines that the benefit to shareholders or other account holders of voting a particular proxy outweighs the revenue lost by terminating the loan, we recall the securities for the purpose of voting the fund's full position.

"SHARE-BLOCKING"

Another example of a situation where Invesco Aim may be unable to vote is in countries where the exercise of voting rights requires the fund to submit to short-term trading restrictions, a practice known as "share-blocking." Invesco Aim generally refrains from voting proxies in share-blocking countries unless the portfolio manager determines that the benefit to fund shareholders and other account holders of voting a specific proxy outweighs the fund's or other account's temporary inability to sell the security.

INTERNATIONAL CONSTRAINTS

An additional concern that sometimes precludes our voting non-U.S. proxies is our inability to receive proxy materials with enough time and enough information to make a voting decision. In the great majority of instances, however, we are able to vote non-U.S. proxies successfully. It is important to note that Invesco Aim makes voting decisions for non-U.S. issuers using these Guidelines as our framework, but also takes into account the corporate-governance standards, regulatory environment and generally accepted best practices of the local market.

EXCEPTIONS TO THESE GUIDELINES

Invesco Aim retains the flexibility to accommodate company-specific situations where strictly adhering to the Guidelines would lead to a vote that the Proxy Committee deems not to be in the best interest of the funds'

E-5

shareholders and other account holders. In these situations, the Proxy Committee will vote the proxy in the manner deemed to be in the best interest of the funds' shareholders and other account holders, and will promptly inform the funds' Boards of Trustees of such vote and the circumstances surrounding it.

RESOLVING POTENTIAL CONFLICTS OF INTEREST

A potential conflict of interest arises when Invesco Aim votes a proxy for an issuer with which it also maintains a material business relationship. Examples could include issuers that are distributors of Invesco Aim's products, or issuers that employ Invesco Aim to manage portions of their retirement plans or treasury accounts. Invesco Aim reviews each proxy proposal to assess the extent, if any, to which there may be a material conflict between the interests of the fund shareholders or other account holders and Invesco Aim.

Invesco Aim takes reasonable measures to determine whether a potential conflict may exist. A potential conflict is deemed to exist only if one or more of the Proxy Committee members actually knew or should have known of the potential conflict.

If a material potential conflict is deemed to exist, Invesco Aim may resolve the potential conflict in one of the following ways: (1) if the proposal that gives rise to the potential conflict is specifically addressed by the Guidelines, Invesco Aim may vote the proxy in accordance with the predetermined Guidelines;
(2) Invesco Aim may engage an independent third party to determine how the proxy should be voted; or (3) Invesco Aim may establish an ethical wall or other informational barrier between the persons involved in the potential conflict and the persons making the proxy-voting decision in order to insulate the potential conflict from the decision makers.

Because the Guidelines are pre-determined and crafted to be in the best economic interest of shareholders and other account holders, applying the Guidelines to vote client proxies should, in most instances, adequately resolve any potential conflict of interest. As an additional safeguard against potential conflicts, persons from Invesco Aim's marketing, distribution and other customer-facing functions are precluded from becoming members of the Proxy Committee.

On a quarterly basis, the AIM Funds Boards of Trustees review a report from Invesco Aim's Internal Compliance Controls Committee. The report contains a list of all known material business relationships that Invesco Aim maintains with publicly traded issuers. That list is cross-referenced with the list of proxies voted over the period. If there are any instances where Invesco Aim's voting pattern on the proxies of its material business partners is inconsistent with its voting pattern on all other issuers, they are brought before the Trustees and explained by the Chairman of the Proxy Committee.

Personal conflicts of interest. If any member of the Proxy Committee has a personal conflict of interest with respect to a company or an issue presented for voting, that Proxy Committee member will inform the Proxy Committee of such conflict and will abstain from voting on that company or issue.

Funds of funds. Some AIM Funds offering diversified asset allocation within one investment vehicle own shares in other AIM Funds. A potential conflict of interest could arise if an underlying AIM Fund has a shareholder meeting with any proxy issues to be voted on, because Invesco Aim's asset-allocation funds or target-maturity funds may be large shareholders of the underlying fund. In order to avoid any potential for a conflict, the asset-allocation funds and target maturity funds vote their shares in the same proportion as the votes of the external shareholders of the underlying fund.

POLICIES AND VOTE DISCLOSURE

A copy of these Guidelines and the voting record of each AIM Fund are available on our web site, www.invescoaim.com. In accordance with Securities and Exchange Commission regulations, all funds file a

E-6

record of all proxy-voting activity for the prior 12 months ending June 30th. That filing is made on or before August 31st of each year.

PROXY VOTING POLICY

INVESCO ASSET MANAGEMENT DEUTSCHLAND GMBH

December 2007

E-8

GENERAL POLICY

INVESCO has responsibility for making investment decisions that are in the best interests of its clients. As part of the investment management services it provides to clients, INVESCO may be authorized by clients to vote proxies appurtenant to the shares for which the clients are beneficial owners.

INVESCO believes that it has a duty to manage clients' assets in the best economic interests of the clients and that the ability to vote proxies is a client asset.

INVESCO reserves the right to amend its proxy policies and procedures from time to time without prior notice to its clients.

PROXY VOTING POLICIES

VOTING OF PROXIES

INVESCO will on a fund by fund basis, decide whether it will vote proxies and if so, for which parts of the portfolio it will voted for. If INVESCO decides to vote proxies, it will do so in accordance with the procedures set forth below. If the client retains in writing the right to vote or if INVESCO determines that any benefit the client might gain from voting a proxy would be outweighed by the costs associated therewith, it will refrain from voting.

BEST ECONOMIC INTERESTS OF CLIENTS

In voting proxies, INVESCO will take into consideration those factors that may affect the value of the security and will vote proxies in a manner in which, in its opinion, is in the best economic interests of clients. INVESCO endeavors to resolve any conflicts of interest exclusively in the best economic interests of clients.

CERTAIN PROXY VOTES MAY NOT BE CAST

In some cases, INVESCO may determine that it is not in the best economic interests of clients to vote proxies. For example, proxy voting in certain countries outside the United States requires share blocking. Shareholders who wish to vote their proxies must deposit their shares 7 to 21 days before the date of the meeting with a designated depositary. During the blocked period, shares to be voted at the meeting cannot be sold until the meeting has taken place and the shares have been returned to the Custodian/Sub-Custodian bank. In addition, voting certain international securities may involve unusual costs to clients. In other cases, it may not be possible to vote certain proxies despite good faith efforts to do so, for instance when inadequate notice of the matter is provided. In the instance of loan securities, voting of proxies typically requires termination of the loan, so it is not usually in the best economic interests of clients to vote proxies on loaned securities. INVESCO typically will not, but reserves the right to, vote where share blocking restrictions, unusual costs or other barriers to efficient voting apply. If INVESCO does not vote, it would have made the determination that the cost of voting exceeds the expected benefit to the client.

ISS SERVICES

INVESCO has contracted with Institutional Shareholder Services ("ISS"), an independent third party service provider, to vote INVESCO's clients' proxies according to ISS's proxy voting recommendations. In addition, ISS will provide proxy analyses, vote recommendations, vote execution and record-keeping services for clients for which INVESCO has proxy voting responsibility. On an annual basis, INVESCO will review information obtained from ISS to ascertain whether ISS (i) has the capacity and competency to adequately analyze proxy issues, and
(ii) can make such recommendations in an impartial manner and in

E-9

the best economic interest of INVESCO's clients. This may include a review of ISS' Policies, Procedures and Practices Regarding Potential Conflicts of Interests and obtaining information about the work ISS does for corporate issuers and the payments ISS receives from such issuers.

Custodians forward proxy materials for clients who rely on INVESCO to vote proxies to ISS. ISS is responsible for exercising the voting rights in accordance with the ISS proxy voting guidelines. If INVESCO receives proxy materials in connection with a client's account where the client has, in writing, communicated to INVESCO that the client, plan fiduciary or other third party has reserved the right to vote proxies, INVESCO will forward to the party appointed by client any proxy materials it receives with respect to the account. In order to avoid voting proxies in circumstances where INVESCO, or any of its affiliates have or may have any conflict of interest, real or perceived, INVESCO has engaged ISS to provide the proxy analyses, vote recommendations and voting of proxies.

In the event that (i) ISS recuses itself on a proxy voting matter and makes no recommendation or (ii) INVESCO decides to override the ISS vote recommendation, the Proxy Voting Committee (PVC) of the International Structured Products Group and the Compliance Officer will review the issue and direct ISS how to vote the proxies as described below.

ISS RECUSAL

When ISS makes no recommendation on a proxy voting issue or is recused due to a conflict of interest, the Proxy Voting Committee (PVC) of the International Structured Products Group and the Compliance Officer will review the issue and, if INVESCO does not have a conflict of interest, direct ISS how to vote the proxies. In such cases where INVESCO has a conflict of interest, INVESCO, in its sole discretion, shall either (a) vote the proxies pursuant to ISS's general proxy voting guidelines, (b) engage an independent third party to provide a vote recommendation, or (c) contact its client(s) for direction as to how to vote the proxies.

OVERRIDE OF ISS RECOMMENDATION

There may be occasions where the INVESCO investment personnel or senior officers seek to override ISS's recommendations if they believe that ISS's recommendations are not in accordance with the best economic interests of clients. In the event that an individual listed above in this section disagrees with an ISS recommendation on a particular voting issue, the individual shall document in writing the reasons that he/she believes that the ISS recommendation is not in accordance with clients' best economic interests and submit such written documentation to the Proxy Voting Committee (PVC) of the International Structured Products Group. Upon review of the documentation and consultation with the individual and others as the PVC deems appropriate, the PVC together with the Compliance Officer may make a determination to override the ISS voting recommendation if they determine that it is in the best economic interests of clients.

PROXY VOTING RECORDS

Clients may obtain information about how INVESCO voted proxies on their behalf by contacting their client services representative. Alternatively, clients may make a written request for proxy voting information.

CONFLICTS OF INTEREST

PROCEDURES TO ADDRESS CONFLICTS OF INTEREST AND IMPROPER INFLUENCE

In order to avoid voting proxies in circumstances where INVESCO or any of its affiliates have or may have any conflict of interest, real or perceived, INVESCO has contracted with ISS to provide proxy analyses, vote recommendations and voting of proxies. Unless noted otherwise by ISS, each vote recommendation provided by ISS to INVESCO includes a representation from ISS that ISS faces no conflict of interest with

E-10

respect to the vote. In instances where ISS has recused itself and makes no recommendation on a particular matter or if an override submission is requested, the Proxy Voting Committee (PVC) of the International Structured Products Group together with the Compliance Officer shall determine how the proxy is to be voted and instruct accordingly in which case the conflict of interest provisions discussed below shall apply.

In effecting the policy of voting proxies in the best economic interests of clients, there may be occasions where the voting of such proxies may present a real or perceived conflict of interest between INVESCO, as the investment manager, and clients.

For each director, officer and employee of INVESCO ("INVESCO person"), the interests of INVESCO's clients must come first, ahead of the interest of INVESCO and any person within the INVESCO organization, which includes INVESCO's affiliates.

Accordingly, each INVESCO person must not put "personal benefit," whether tangible or intangible, before the interests of clients of INVESCO or otherwise take advantage of the relationship to INVESCO's clients. "Personal benefit" includes any intended benefit for oneself or any other individual, company, group or organization of any kind whatsoever, except a benefit for a client of INVESCO, as appropriate. It is imperative that each of INVESCO's directors, officers and employees avoid any situation that might compromise, or call into question, the exercise of fully independent judgment in the interests of INVESCO's clients.

Occasions may arise where a person or organization involved in the proxy voting process may have a conflict of interest. A conflict of interest may also exist if INVESCO has a business relationship with (or is actively soliciting business from) either the company soliciting the proxy or a third party that has a material interest in the outcome of a proxy vote or that is actively lobbying for a particular outcome of a proxy vote. An INVESCO person shall not be considered to have a conflict of interest if the INVESCO person did not know of the conflict of interest and did not attempt to influence the outcome of a proxy vote. Any individual with actual knowledge of a conflict of interest relating to a particular referral item shall disclose that conflict to the Compliance Officer.

The following are examples of situations where a conflict may exist:

- Business Relationships - where INVESCO manages money for a company or an employee group, manages pension assets or is actively soliciting any such business, or leases office space from a company;

- Personal Relationships - where a INVESCO person has a personal relationship with other proponents of proxy proposals, participants in proxy contests, corporate directors, or candidates for directorships; and

- Familial Relationships - where an INVESCO person has a known familial relationship relating to a company (e.g. a spouse or other relative who serves as a director of a public company or is employed by the company).

In the event that INVESCO (or an affiliate) manages assets for a company, its pension plan, or related entity and where clients' funds are invested in that company's shares, it will not take into consideration this relationship and will vote proxies in that company solely in the best economic interest of its clients.

It is the responsibility of the INVESCO person to report any real or potential conflict of interest of which such individual has actual knowledge to the Compliance Officer, who shall present any such information to the Head of Continental Europe Compliance. However, once a particular conflict has been reported to the Compliance Officer, this requirement shall be deemed satisfied with respect to all individuals with knowledge of such conflict.

E-11

In addition, any INVESCO person who submits an ISS override recommendation to the Proxy Voting Committee (PVC) of the International Structured Products Group shall certify as to their compliance with this policy concurrently with the submission of their override recommendation. A form of such certification is attached as Appendix A hereto.

In addition, the Proxy Voting Committee (PVC) of the International Structured Products Group must notify INVESCO's Compliance Officer with impunity and without fear of retribution or retaliation, of any direct, indirect or perceived improper influence made by anyone within INVESCO or by an affiliated company's representatives with regard to how INVESCO should vote proxies. The Compliance Officer will investigate the allegations and will report his or her findings to the INVESCO Risk Management Committee and to the Head of Continental Europe Compliance. In the event that it is determined that improper influence was made, the Risk Management Committee will determine the appropriate action to take which may include, but is not limited to, (1) notifying the affiliated company's Chief Executive Officer, its Management Committee or Board of Directors, (2) taking remedial action, if necessary, to correct the result of any improper influence where clients have been harmed, or (3) notifying the appropriate regulatory agencies of the improper influence and to fully cooperate with these regulatory agencies as required. In all cases, the Proxy Voting Committee (PVC) of the International Structured Products Group together with the Compliance Officer shall not take into consideration the improper influence in determining how to vote proxies and will vote proxies solely in the best economic interest of clients.

PROXY POLICY APPLIES TO THE FOLLOWING:

INVESCO ASSET MANAGEMENT LIMITED

INVESCO PERPETUAL
POLICY ON CORPORATE GOVERNANCE
(Updated February 2008)

1. INTRODUCTION

Invesco Perpetual (IP), the trading name of Invesco Asset Management Limited, has adopted a clear and considered policy towards its responsibility as a shareholder. As part of this policy, IP will take steps to satisfy itself about the extent to which the companies in which it invests comply with local recommendations and practices, such as the UK Combined Code issued by the Committee on Corporate Governance and/or the U.S. Department of Labor Interpretive Bulletins.

2. RESPONSIBLE VOTING

IP has a responsibility to optimise returns to its clients. As a core part of the investment process, Fund Managers will endeavour to establish a dialogue with management to promote company decision making that is in the best interests of shareholders, and is in accordance with good Corporate Governance principles.

IP considers that shareholder activism is fundamental to good Corporate Governance. Whilst this does not entail intervening in daily management decisions, it does involve supporting general standards for corporate activity and, where necessary, taking the initiative to ensure those standards are met.

One important means of putting shareholder responsibility into practice is via the exercising of voting rights. In deciding whether to vote shares, IP will take into account such factors as the likely impact of voting on management activity, and where expressed, the preference of clients. As a result of these two factors, IP will tend to vote on all UK and European shares, but to vote on a more selective basis on other shares. (See Appendix I - Voting on non-UK/European shares)

IP considers that the voting rights attached to its clients' investments should be actively managed with the same duty of care as that applied to all other aspects of asset administration. As such, voting rights will be exercised on an informed and independent basis, and will not simply be passed back to the company concerned for discretionary voting by the Chairman. In doing this, IP will have in mind three objectives:

i) To protect the rights of its clients

ii) To minimise the risk of financial or business impropriety within the companies in which its clients are invested, and

iii) To protect the long-term value of its clients' investments.

It is important to note that, when exercising voting rights, a third option of abstention can also be used as a means of expressing dissatisfaction, or lack of support, to a Board on a particular issue. Additionally, in the event of a conflict of interest arising between IP and its clients over a specific issue, IP will either abstain or seek instruction from each client.

IP will exercise actively the voting rights represented by the shares it manages on behalf of its investors.

Note: Share Blocking

Generally, IP will not vote where this results in shares being blocked from trading for a period of more than a few hours. IP considers that it is not in the interest of clients that their shares are blocked at a potentially sensitive time, such as that around a shareholder meeting.

E-14

3. VOTING PROCEDURES

IP will endeavour to keep under regular review with trustees, depositaries and custodians the practical arrangements for circulating company resolutions and notices of meetings and for exercising votes in accordance with standing or special instructions.

IP will endeavour to review regularly any standing or special instructions on voting and where possible, discuss with company representatives any significant issues.

IP will take into account the implications of stock lending arrangements where this is relevant (that is, when stock is lent to the extent permitted by local regulations, the voting rights attaching to that stock pass to the borrower). If a stock is on loan and therefore cannot be voted, it will not necessarily be recalled in instances where we would vote with management. Individual IP Fund Managers enter securities lending arrangements at their own discretion and where they believe it is for the potential benefit of their investors.

4. DIALOGUE WITH COMPANIES

IP will endeavour, where practicable in accordance with its investment processes, to enter into a dialogue with companies based on the mutual understanding of objectives. This dialogue is likely to include regular meetings with company representatives to explore any concerns about corporate governance where these may impact on the best interests of clients. In discussion with Company Boards and senior non-Executive Directors, IP will endeavour to cover any matters with particular relevance to shareholder value.

Specifically when considering resolutions put to shareholders, IP will pay attention to the companies' compliance with the relevant local requirements. In addition, when analysing the company's prospects for future profitability and hence returns to shareholders, IP will take many variables into account, including but not limited to, the following:

[ ] Nomination and audit committees

[ ] Remuneration committee and directors' remuneration

[ ] Board balance and structure

[ ] Financial reporting principles

[ ] Internal control system and annual review of its effectiveness

[ ] Dividend and Capital Management policies

5. NON-ROUTINE RESOLUTIONS AND OTHER TOPICS

These will be considered on a case-by-case basis and where proposals are put to the vote will require proper explanation and justification by (in most instances) the Board. Examples of such would be all SRI issues (i.e. those with social, environmental or ethical connotations), political donations, and any proposal raised by a shareholder or body of shareholders (typically a pressure group).

Apart from the three fundamental voting objectives set out under 'Responsible Voting' above, considerations that IP might apply to non-routine proposals will include:

i) The degree to which the company's stated position on the issue could affect its reputation and/or sales, or leave it vulnerable to boycott or selective purchasing

ii) What other companies have done in response to the issue

iii) Whether implementation would achieve the objectives sought in the proposal

iv) Whether the matter is best left to the Board's discretion.

6. EVALUATION OF COMPANIES' CORPORATE GOVERNANCE ARRANGEMENTS

IP will, when evaluating companies' governance arrangements, particularly those relating to board structure and composition, give due weight to all relevant factors drawn to their attention.

On request from clients, IP will in good faith provide records of voting instructions given to third parties such as trustees, depositaries and custodians provided that

(i) in IP's discretion, to do so does not conflict with the best interests of other clients and

(ii) it is understood that IP will not be held accountable for the expression of views within such voting instructions and

(iii) IP are not giving any assurance nor undertaking any obligation to ensure that such instructions resulted in any votes actually being cast. Records of voting instructions within the immediate preceding 3 months will not normally be provided.

Note: The record of votes will reflect the voting instruction of the relevant Fund Manager. This may not be the same as votes actually cast as IP is entirely reliant on third parties complying promptly with such instructions to ensure that such votes are cast correctly. Accordingly, the provision of information relating to an instruction does not mean that a vote was actually cast, just that an instruction was given in accordance with a particular view taken.

E-16

APPENDIX I

VOTING ON NON-UK/EUROPEAN SHARES

When deciding whether to exercise the voting rights attached to its clients' non-UK/European shares, IP will take into consideration a number of factors. These will include:

- the likely impact of voting on management activity, versus the cost to the client

- the portfolio management restrictions (e.g. share blocking) that may result from voting

- the preferences, where expressed, of clients

Generally, IP will vote on non-UK/European shares by exception only, except where the client or local regulator expressly requires voting on all shares.

SHARE BLOCKING

Generally, IP will not vote where this results in shares being blocked from trading for a period of more than a few hours. IP considers that it is not in the interest of clients that their shares are blocked at a potentially sensitive time, such as that around a shareholder meeting."

One way INVESCO represents its clients in matters of corporate governance is through the proxy voting process.

This document sets out INVESCO's policy in relation to proxy voting. It has been approved by the INVESCO Australia Limited Board.

2. Scope

This policy applies to all INVESCO portfolios with the following exceptions:

3. Policy

In accordance with industry practices and the IFSA standard on proxy voting, our policy is as follows:

- INVESCO's overriding principle is that votes will be cast in the best economic interests of investors.

- INVESCO's intention is to vote on all Australian Company shareholder resolutions however it recognizes that in some circumstances it would be inappropriate to vote, or its vote may be immaterial. INVESCO will generally abstain from voting on "routine" company resolutions (eg approval of financial accounts or housekeeping amendments to Articles of Association or Constitution) unless its clients' portfolios in aggregate represent a significant proportion of the shareholdings of the company in question (a significant proportion in this context means 5% or more of the market capitalisation of the company).

- INVESCO will always vote on the following issues arising in company Annual General Meetings where it has the authority to do so on behalf of clients.

- contentious issues (eg. issues of perceived national interest, or where there has been extensive press coverage or public comment);

- employee and executive share and option schemes;

- approval of changes of substantial shareholdings;

- mergers or schemes of arrangement; and

- approval of major asset sales or purchases.

- Management agreements or mandates for individually-managed clients will provide direction as to who has responsibility for voting.

- In the case of existing management agreements which do not contain a provision concerning voting authority or are ambiguous on the subject, INVESCO will not vote until clear instructions have been received from the client.

- In the case of clients who wish to place special conditions on the delegation of proxy voting powers, INVESCO will endeavour to accommodate those clients'

E-26

requirements as far as practicable, subject to any administrative obstacles or additional costs that might arise in implementing the conditions.

- In considering proxy voting issues arising in respect of unit-holders in managed investment schemes, INVESCO will act solely in accordance with its fiduciary responsibility to take account of the collective interests of unit-holders in the scheme as a whole. INVESCO cannot accept instructions from individual unit-holders as to the exercise of proxy voting authority in a particular instance.

- In order to facilitate its proxy voting process, INVESCO may retain a professional proxy voting service to assist with in-depth proxy research, vote execution, and the necessary record keeping.

4. Reporting and Disclosure

A written record will be kept of the voting decision in each case, and of the reasons for each decision (including abstentions).

INVESCO will disclose on an annual basis, a summary of its proxy voting statistics on its website as required by IFSA standard No. 13 - Proxy Voting.

5. Conflicts of Interest

All INVESCO employees are under an obligation to be aware of the potential for conflicts of interest with respect to voting proxies on behalf of clients.

INTRODUCTION

This policy sets out Invesco's approach to proxy voting in the context of our broader portfolio management and client service responsibilities. It applies to Asia related equity portfolios managed by Invesco on behalf of individually-managed clients and pooled fund clients

Invesco's proxy voting policy is expected to evolve over time to cater for changing circumstances or unforeseen events.

E-30

1. GUIDING PRINCIPLES

1.1 Invesco recognizes its fiduciary obligation to act in the best interests of all clients, be they retirement scheme trustees, institutional clients, unitholders in pooled investment vehicles or personal investors. The application of due care and skill in exercising shareholder responsibilities is a key aspect of this fiduciary obligation.

1.2 The sole objective of Invesco's proxy voting policy is to promote the economic interests of its clients. At no time will Invesco use the shareholding powers exercised in respect of its clients' investments to advance its own commercial interests, to pursue a social or political cause that is unrelated to clients' economic interests, or to favour a particular client or other relationship to the detriment of others.

1.3 Invesco also recognizes the broader chain of accountability that exists in the proper governance of corporations, and the extent and limitations of the shareholder's role in that process. In particular, it is recognized that company management should ordinarily be presumed to be best placed to conduct the commercial affairs of the enterprise concerned, with prime accountability to the enterprise's Board of Directors which is in turn accountable to shareholders and to external regulators and exchanges. The involvement of Invesco as an institutional shareholder will not extend to interference in the proper exercise of Board or management responsibilities, or impede the ability of companies to take the calculated commercial risks which are essential means of adding value for shareholders.

1.4 The primary aim of the policy is to encourage a culture of performance among investee companies, rather than one of mere conformance with a prescriptive set of rules and constraints. Rigid adherence to a checklist approach to corporate governance issues is of itself unlikely to promote the maximum economic performance of companies, or to cater for circumstances in which non-compliance with a checklist is appropriate or unavoidable.

1.5 Invesco considers that proxy voting rights are an asset which should be managed with the same care as any other asset managed on behalf of its clients.

E-31

2. PROXY VOTING AUTHORITY

2.1 An important dimension of Invesco's approach to corporate governance is the exercise of proxy voting authority at the Annual General Meetings or other decision-making forums of companies in which we manage investments on behalf of clients.

2.2 An initial issue to consider in framing a proxy voting policy is the question of where discretion to exercise voting power should rest - with Invesco as the investment manager, or with each individual client? Under the first alternative, Invesco's role would be both to make voting decisions on clients' behalf and to implement those decisions. Under the second alternative, Invesco would either have no role to play, or its role would be limited solely to implementing voting decisions under instructions from our clients.

2.3 In addressing this issue, it is necessary to distinguish the different legal structures and fiduciary relationships which exist as between individually-managed clients, who hold investments directly on their own accounts, and pooled fund clients, whose investments are held indirectly under a trust structure.

2.4 Individually-Managed Clients

2.4.1 As a matter of general policy, Invesco believes that unless a client's mandate gives specific instructions to the contrary, discretion to exercise votes should normally rest with the investment manager, provided that the discretion is always exercised in the client's interests alone.

2.4.2 The reason for this position is that Invesco believes that, with its dedicated research resources and ongoing monitoring of companies, an investment manager is usually better placed to identify issues upon which a vote is necessary or desirable. We believe it is also more practical that voting discretion rests with the party that has the authority to buy and sell shares, which is essentially what investment managers have been engaged to do on behalf of their clients.

2.4.3 In cases where voting authority is delegated by an individually-managed client, Invesco recognizes its responsibility to be accountable for the decisions it makes. If a client requires, an appropriate reporting mechanism will be put in place.

2.4.4 While it is envisaged that the above arrangements will be acceptable in the majority of cases, it is recognized that some individually-managed clients will wish to retain voting authority for themselves, or to place conditions on the circumstances in which it can be exercised by investment managers. In practice, it is believed that this option is generally only likely to arise with relatively large clients such as trustees of major superannuation funds or statutory corporations which have the resources to develop their own policies and to supervise their implementation by investment managers and custodians. In particular, clients who have multiple equity managers and utilize a master custody arrangement may be more likely to consider retaining voting authority in order to ensure consistency of approach across their total portfolio.

2.4.5 In any event, whatever decision is taken as to where voting authority should lie, Invesco believes that the matter should be explicitly covered by the terms of the investment management agreement and clearly understood by the respective parties.

2.4.6 Accordingly, Invesco will pursue the following policies with respect to the exercise of proxy voting authority for individually-managed clients:

E-32

PROXY VOTING AUTHORITY

Individually-Managed Clients

Unless an individually-managed client wishes to retain proxy voting authority, Invesco will assume proxy voting authority by way of delegation from the client, provided that the allocation of proxy voting responsibility is clearly set out in the investment management agreement.

In the case of clients who wish to place special conditions on the delegation of proxy voting powers, Invesco will endeavour to accommodate those clients' requirements as far as practicable, subject to any administrative obstacles or additional costs that might arise in implementing the conditions.

2.5 POOLED FUND CLIENTS

2.5.1 The legal relationship between an investment manager and its pooled fund clients is different in a number of important respects from that applying to individually-managed clients. These differences have a bearing on how proxy voting authority is exercised on behalf of pooled fund clients.

2.5.2 These legal relationships essentially mean that the manager is required to act solely in the collective interests of unitholders at large rather than as a direct agent or delegate of each unitholder. On the issue of proxy voting, as with all other aspects of our client relationships, Invesco will naturally continue to be receptive to any views and concerns raised by its pooled fund clients. However, the legal relationship that exists means it is not possible for the manager to accept instructions from a particular pooled fund client as to how to exercise proxy voting authority in a particular instance.

2.5.3 As in the case of individually-managed clients who delegate their proxy voting authority, Invesco's accountability to pooled fund clients in exercising its fiduciary responsibilities is best addressed as part of the manager's broader client relationship and reporting responsibilities.

2.5.4 Accordingly, Invesco will pursue the following policies with respect to the exercise of proxy voting authority for pooled fund clients:

PROXY VOTING AUTHORITY

Pooled Fund Clients

In considering proxy voting issues arising in respect of pooled fund shareholdings, Invesco will act solely in accordance with its fiduciary responsibility to take account of the collective interests of unitholders in the pooled fund as a whole.

Invesco cannot accept instructions from individual unitholders as to the exercise of proxy voting authority in a particular instance.

E-33

3. KEY PROXY VOTING ISSUES

3.1 This section outlines Invesco's intended approach in cases where proxy voting authority is being exercised on clients' behalf.

3.2 Invesco will vote on all material issues at all company meetings where it has the voting authority and responsibility to do so. We will not announce our voting intentions and the reasons behind them.

3.3 Invesco applies two underlying principles. First, our interpretation of 'material voting issues' is confined to those issues which affect the value of shares we hold on behalf of clients and the rights of shareholders to an equal voice in influencing the affairs of companies in proportion to their shareholdings. We do not consider it appropriate to use shareholder powers for reasons other than the pursuit of these economic interests. Second, we believe that a critical factor in the development of an optimal corporate governance policy is the need to avoid unduly diverting resources from our primary responsibilities to add value to our clients' portfolios through investment performance and client service.

3.4 In order to expand upon these principles, Invesco believes it is necessary to consider the role of proxy voting policy in the context of broader portfolio management and administrative issues which apply to our investment management business as a whole. These are discussed as follows.

3.5 PORTFOLIO MANAGEMENT ISSUES - ACTIVE EQUITY PORTFOLIOS

3.5.1 While recognizing in general terms that issues concerning corporate governance practices can have a significant bearing on the financial performance of companies, the primary criterion for the selection and retention of a particular stock in active equity portfolios remains our judgment that the stock will deliver superior investment performance for our clients, based on our investment themes and market analysis.

3.5.2 In view of these dynamics, Invesco does not consider it feasible or desirable to prescribe in advance comprehensive guidelines as to how it will exercise proxy voting authority in all circumstances. The primary aim of Invesco's approach to corporate governance is to encourage a culture of performance among the companies in which we manage investments in order to add value to our clients' portfolios, rather than one of mere conformance with a prescriptive set of rules and constraints.

3.5.3 Nevertheless, Invesco has identified a limited range of issues upon which it will always exercise proxy voting authority - either to register disapproval of management proposals or to demonstrate support for company initiatives through positive use of voting powers. These issues are outlined as follows:

KEY VOTING ISSUES

Major Corporate Proposals

Invesco will always vote on the following issues arising in company General Meetings where it has the authority to do so on behalf of clients.

- contentious issues (eg. issues of perceived national interest, or where there has been extensive press coverage or public comment);

- approval of changes of substantial shareholdings;

- mergers or schemes of arrangement; and

- approval of major asset sales or purchases.

E-34

As a general rule, Invesco will vote against any actions that will reduce the rights or options of shareholders, reduce shareholder influence over the board of directors and management, reduce the alignment of interests between management and shareholders, or reduce the value of shareholders' investments, unless balanced by reasonable increase in net worth of the shareholding.

Where appropriate, Invesco will also use voting powers to influence companies to adopt generally accepted best corporate governance practices in areas such as board composition, disclosure policies and the other areas of recommended corporate governance practice.

Invesco's approach to significant proxy voting issues which fall outside these areas will be addressed on their merits.

3.6 ADMINISTRATIVE ISSUES

3.6.1 In addition to the portfolio management issues outlined above, Invesco's proxy voting policy also takes account of administrative and cost implications, together with the size of our holdings as compared to the issue size, involved in the exercise of proxy voting authority on our clients' behalf.

3.6.2 There are practical constraints to the implementation of proxy voting decisions. Proxy voting is a highly seasonal activity, with most company Annual General Meetings being collapsed into a few months, with short deadlines for the distribution and return of notice papers, multiple resolutions from multiple companies being considered simultaneously, and under a legal system which is essentially dependent upon paper-based communication and record-keeping.

3.6.3 In addition, for investment managers such as Invesco who do not invest as principals and who consequently do not appear directly on the share registers of companies, all of these communications are channelled through external custodians, among whom there is in turn a considerable variation in the nature and quality of systems to deal with the flow of information.

3.6.4 While Invesco has the systems in place to efficiently implement proxy voting decisions when required, it can be seen that administrative and cost considerations by necessity play an important role in the application of a responsible proxy voting policy. This is particularly so bearing in mind the extremely limited time period within which voting decisions must often be made and implemented (which can in practice be as little as a few days). This factor also explains why Invesco resists any suggestion that there should be compulsory proxy voting on all issues, as in our view this would only increase the costs to be borne by our clients with very little practical improvement in corporate performance in most cases.

3.6.5 These administrative constraints are further highlighted by the fact that many issues on which shareholders are in practice asked to vote are routine matters relating to the ongoing administration of the company - eg. approval of financial accounts or housekeeping amendments to Articles of Association. Generally in such cases, we will be in favour of the motion as most companies take seriously their duties and are acting in the best interests of shareholders. However, the actual casting of a "yes" vote on all such resolutions in our view would entail an unreasonable administrative workload and cost.

3.6.6 Accordingly, Invesco believes that an important consideration in the framing of a proxy voting policy is the need to avoid unduly diverting resources from our primary responsibilities to add value to our clients' investments through portfolio management and client service. The policies outlined below have been prepared on this basis.

E-35

KEY PROXY VOTING ISSUES

Administrative Constraints

In view of the administrative constraints and costs involved in the exercise of proxy voting powers, Invesco may (depending on circumstances) not exercise its voting right unless its clients' portfolios in aggregate represent a significant proportion of the shareholdings of the company in question.

A significant proportion in this context means 5% or more of the market capitalisation of the company.

E-36

4. INTERNAL ADMINISTRATION & DECISION-MAKING PROCESS

4.1 The following diagram illustrates the procedures adopted by Invesco for the administration of proxy voting:

            |                        |
            --------------------------

4.2 As shown by the diagram, a central administrative role is performed by our Settlement Team, located within the Client Administration section. The initial role of the Settlement Team is to receive company notice papers via the range of custodians who hold shares on behalf of our clients, to ascertain which client portfolios hold the stock, and to initiate the decision-making process by distributing the company notice papers to the Primary Investment Manager responsible for the company in question.

4.3 A voting decision on each company resolution (whether a yes or no vote, or a recommended abstention) is made by the Primary Investment Manager responsible for the company in question. Invesco believes that this approach is preferable to the appointment of a committee with responsibility for handling voting issues across all companies, as it takes advantage of the expertise of individuals whose professional lives are occupied by analysing particular companies and sectors, and who are familiar with the issues facing particular companies through their regular company visits.

4.4 Moreover, the Primary Equity Manager has overall responsibility for the relevant market and this ensures that similar issues which arise in different companies are handled in a consistent way across the relevant market.

4.5 The voting decision is then documented and passed back to the Settlement Team, who issue the voting instructions to each custodian in advance of the closing date for receipt of proxies by the company. At the same time, the Settlement Team logs all proxy voting activities for record keeping or client reporting purposes.

4.6 A key task in administering the overall process is the capture and dissemination of data from companies and custodians within a time frame that makes exercising votes feasible in practice. This applies particularly during the company Annual General Meeting "season", when there are typically a large number of proxy voting issues under consideration simultaneously. Invesco has no

E-37

control over the former dependency and Invesco's ability to influence a custodian's service levels are limited in the case of individually-managed clients, where the custodian is answerable to the client.

4.7 The following policy commitments are implicit in these administrative and decision-making processes:

INTERNAL ADMINISTRATION AND DECISION-MAKING PROCESS

Invesco will consider all resolutions put forward in the Annual General Meetings or other decision-making forums of all companies in which investments are held on behalf of clients, where it has the authority to exercise voting powers. This consideration will occur in the context of our policy on Key Voting Issues outlined in Section 3.

The voting decision will be made by the Primary Investment Manager responsible for the market in question.

A written record will be kept of the voting decision in each case, and in case of an opposing vote, the reason/comment for the decision.

Voting instructions will be issued to custodians as far as practicable in advance of the deadline for receipt of proxies by the company. Invesco will monitor the efficiency with which custodians implement voting instructions on clients' behalf.

Invesco's ability to exercise proxy voting authority is dependent on timely receipt of notification from the relevant custodians.

E-38

5. CLIENT REPORTING

5.1 Invesco will keep records of its proxy voting activities.

5.2 Upon client request, Invesco will regularly report back to the client on proxy voting activities for investments owned by the client.

5.2 The following points summarise Invesco's policy commitments on the reporting of proxy voting activities to clients (other than in cases where specific forms of client reporting are specified in the client's mandate):

CLIENT REPORTING

Where proxy voting authority is being exercised on a client's behalf, a statistical summary of voting activity will be provided on request as part of the client's regular quarterly report.

Invesco will provide more detailed information on particular proxy voting issues in response to requests from clients wherever possible.

PROXY VOTING POLICIES

AND

PROCEDURES

April 1, 2006

E-40

GENERAL POLICY

INVESCO Institutional (N.A.), Inc. and its wholly-owned subsidiaries, and INVESCO Global Asset Management (N.A.), Inc. (collectively, "INVESCO"), each has responsibility for making investment decisions that are in the best interests of its clients. As part of the investment management services it provides to clients, INVESCO may be authorized by clients to vote proxies appurtenant to the shares for which the clients are beneficial owners.

INVESCO believes that it has a duty to manage clients' assets in the best economic interests of the clients and that the ability to vote proxies is a client asset.

INVESCO reserves the right to amend its proxy policies and procedures from time to time without prior notice to its clients.

PROXY VOTING POLICIES

VOTING OF PROXIES

INVESCO will vote client proxies in accordance with the procedures set forth below unless the client for non-ERISA clients retains in writing the right to vote, the named fiduciary (e.g., the plan sponsor) for ERISA clients retains in writing the right to direct the plan trustee or a third party to vote proxies or INVESCO determines that any benefit the client might gain from voting a proxy would be outweighed by the costs associated therewith.

BEST ECONOMIC INTERESTS OF CLIENTS

In voting proxies, INVESCO will take into consideration those factors that may affect the value of the security and will vote proxies in a manner in which, in its opinion, is in the best economic interests of clients. INVESCO endeavors to resolve any conflicts of interest exclusively in the best economic interests of clients.

ISS SERVICES

INVESCO has contracted with Institutional Shareholder Services ("ISS"), an independent third party service provider, to vote INVESCO's clients' proxies according to ISS's proxy voting recommendations. In addition, ISS will provide proxy analyses, vote recommendations, vote execution and record-keeping services for clients for which INVESCO has proxy voting responsibility. On an annual basis, INVESCO will review information obtained from ISS to ascertain whether ISS (i) has the capacity and competency to adequately analyze proxy issues, and
(ii) can make such recommendations in an impartial manner and in the best economic interest of INVESCO's clients. This may include a review of ISS' Policies, Procedures and Practices Regarding Potential Conflicts of Interests and obtaining information about the work ISS does for corporate issuers and the payments ISS receives from such issuers.

Custodians forward proxy materials for clients who rely on INVESCO to vote proxies to ISS. ISS is responsible for exercising the voting rights in accordance with the ISS proxy voting guidelines. If INVESCO receives proxy materials in connection with a client's account where the client has, in writing, communicated to INVESCO that the client, plan fiduciary or other third party has reserved the right to vote proxies, INVESCO will forward to the party appointed by client any proxy materials it receives with respect to the account. In order to avoid voting proxies in circumstances where INVESCO, or any of its affiliates have or may have any conflict of interest, real or perceived, INVESCO has engaged ISS to provide the proxy analyses, vote recommendations and voting of proxies.

E-41

In the event that (i) ISS recuses itself on a proxy voting matter and makes no recommendation or (ii) INVESCO decides to override the ISS vote recommendation, the Proxy Committee will review the issue and direct ISS how to vote the proxies as described below.

PROXY COMMITTEE

The Proxy Committee shall have seven (7) members, which shall include representatives from portfolio management, operations, and legal/compliance or other functional departments as deemed appropriate who are knowledgeable regarding the proxy process. A majority of the members of the Proxy Committee shall constitute a quorum and the Proxy Committee shall act by a majority vote. The chair of the Proxy Committee shall be chosen by the Chief Compliance Officer of INVESCO. The Proxy Committee shall keep minutes of its meetings that shall be kept with the proxy voting records of INVESCO. The Proxy Committee will appoint a Proxy Manager to manage the proxy voting process, which includes the voting of proxies and the maintenance of appropriate records.

Proxy Committee meetings shall be called by the Proxy Manager when override submissions are made and in instances when ISS has recused itself from a vote recommendation. In these situations, the Proxy Committee shall meet and determine how proxies are to be voted in the best interests of clients.

The Proxy Committee periodically reviews new types of corporate governance issues, evaluates proposals not addressed by the ISS proxy voting guidelines in instances when ISS has recused itself, and determines how INVESCO should vote. The Committee monitors adherence to these Procedures, industry trends and reviews the ISS proxy voting guidelines.

ISS RECUSAL

When ISS makes no recommendation on a proxy voting issue or is recused due to a conflict of interest, the Proxy Committee will review the issue and, if INVESCO does not have a conflict of interest, direct ISS how to vote the proxies. In such cases where INVESCO has a conflict of interest, INVESCO, in its sole discretion, shall either (a) vote the proxies pursuant to ISS's general proxy voting guidelines, (b) engage an independent third party to provide a vote recommendation, or (c) contact its client(s) for direction as to how to vote the proxies.

OVERRIDE OF ISS RECOMMENDATION

There may be occasions where the INVESCO investment personnel, senior officers or a member of the Proxy Committee seek to override ISS's recommendations if they believe that ISS's recommendations are not in accordance with the best economic interests of clients. In the event that an individual listed above in this section disagrees with an ISS recommendation on a particular voting issue, the individual shall document in writing the reasons that he/she believes that the ISS recommendation is not in accordance with clients' best economic interests and submit such written documentation to the Proxy Manager for consideration by the Proxy Committee. Upon review of the documentation and consultation with the individual and others as the Proxy Committee deems appropriate, the Proxy Committee may make a determination to override the ISS voting recommendation if the Committee determines that it is in the best economic interests of clients and the Committee has addressed conflict of interest issues as discussed below.

PROXY COMMITTEE MEETINGS

When a Proxy Committee Meeting is called, whether because of an ISS recusal or request for override of an ISS recommendation, the Proxy Committee shall review the report of the Chief Compliance Officer as to whether any INVESCO person has reported a conflict of interest.

The Proxy Committee shall review the information provided to it to determine if a real or perceived conflict of interest exists and the minutes of the Proxy Committee shall:

(1) describe any real or perceived conflict of interest,

E-42

(2) discuss any procedure used to address such conflict of interest,

(3) report any contacts from outside parties (other than routine communications from proxy solicitors), and

(4) include confirmation that the recommendation as to how the proxies are to be voted is in the best economic interests of clients and was made without regard to any conflict of interest.

Based on the above review and determinations, the Proxy Committee will direct ISS how to vote the proxies.

CERTAIN PROXY VOTES MAY NOT BE CAST

In some cases, INVESCO may determine that it is not in the best economic interests of clients to vote proxies. For example, proxy voting in certain countries outside the United States requires share blocking. Shareholders who wish to vote their proxies must deposit their shares 7 to 21 days before the date of the meeting with a designated depositary. During the blocked period, shares to be voted at the meeting cannot be sold until the meeting has taken place and the shares have been returned to the Custodian/Sub-Custodian bank. In addition, voting certain international securities may involve unusual costs to clients. In other cases, it may not be possible to vote certain proxies despite good faith efforts to do so, for instance when inadequate notice of the matter is provided. In the instance of loan securities, voting of proxies typically requires termination of the loan, so it is not usually in the best economic interests of clients to vote proxies on loaned securities. INVESCO typically will not, but reserves the right to, vote where share blocking restrictions, unusual costs or other barriers to efficient voting apply. If INVESCO does not vote, it would have made the determination that the cost of voting exceeds the expected benefit to the client. The Proxy Manager shall record the reason for any proxy not being voted, which record shall be kept with the proxy voting records of INVESCO.

PROXY VOTING RECORDS

Clients may obtain information about how INVESCO voted proxies on their behalf by contacting their client services representative. Alternatively, clients may make a written request for proxy voting information to: Proxy Manager, 1360 Peachtree Street, N.E., Atlanta, Georgia 30309.

CONFLICTS OF INTEREST

PROCEDURES TO ADDRESS CONFLICTS OF INTEREST AND IMPROPER INFLUENCE

In order to avoid voting proxies in circumstances where INVESCO or any of its affiliates have or may have any conflict of interest, real or perceived, INVESCO has contracted with ISS to provide proxy analyses, vote recommendations and voting of proxies. Unless noted otherwise by ISS, each vote recommendation provided by ISS to INVESCO includes a representation from ISS that ISS faces no conflict of interest with respect to the vote. In instances where ISS has recused itself and makes no recommendation on a particular matter or if an override submission is requested, the Proxy Committee shall determine how the proxy is to be voted and instruct the Proxy Manager accordingly in which case the conflict of interest provisions discussed below shall apply.

In effecting the policy of voting proxies in the best economic interests of clients, there may be occasions where the voting of such proxies may present a real or perceived conflict of interest between INVESCO, as the investment manager, and clients.

For each director, officer and employee of INVESCO ("INVESCO person"), the interests of INVESCO's clients must come first, ahead of the interest of INVESCO and any person within the INVESCO organization, which includes INVESCO's affiliates.

E-43

Accordingly, each INVESCO person must not put "personal benefit," whether tangible or intangible, before the interests of clients of INVESCO or otherwise take advantage of the relationship to INVESCO's clients. "Personal benefit" includes any intended benefit for oneself or any other individual, company, group or organization of any kind whatsoever, except a benefit for a client of INVESCO, as appropriate. It is imperative that each of INVESCO's directors, officers and employees avoid any situation that might compromise, or call into question, the exercise of fully independent judgment in the interests of INVESCO's clients.

Occasions may arise where a person or organization involved in the proxy voting process may have a conflict of interest. A conflict of interest may also exist if INVESCO has a business relationship with (or is actively soliciting business from) either the company soliciting the proxy or a third party that has a material interest in the outcome of a proxy vote or that is actively lobbying for a particular outcome of a proxy vote. An INVESCO person (excluding members of the Proxy Committee) shall not be considered to have a conflict of interest if the INVESCO person did not know of the conflict of interest and did not attempt to influence the outcome of a proxy vote. Any individual with actual knowledge of a conflict of interest relating to a particular referral item shall disclose that conflict to the Chief Compliance Officer.

The following are examples of situations where a conflict may exist:

- Business Relationships - where INVESCO manages money for a company or an employee group, manages pension assets or is actively soliciting any such business, or leases office space from a company;

- Personal Relationships - where a INVESCO person has a personal relationship with other proponents of proxy proposals, participants in proxy contests, corporate directors, or candidates for directorships; and

- Familial Relationships - where an INVESCO person has a known familial relationship relating to a company (e.g. a spouse or other relative who serves as a director of a public company or is employed by the company).

In the event that INVESCO (or an affiliate) manages assets for a company, its pension plan, or related entity or where any member of the Proxy Committee has a personal conflict of interest, and where clients' funds are invested in that company's shares, the Proxy Committee will not take into consideration this relationship and will vote proxies in that company solely in the best economic interest of its clients.

It is the responsibility of the Proxy Manager and each member of the Proxy Committee to report any real or potential conflict of interest of which such individual has actual knowledge to the Chief Compliance Officer, who shall present any such information to the Proxy Committee. However, once a particular conflict has been reported to the Chief Compliance Officer, this requirement shall be deemed satisfied with respect to all individuals with knowledge of such conflict.

In addition, the Proxy Manager and each member of the Proxy Committee shall certify annually as to their compliance with this policy. In addition, any INVESCO person who submits an ISS override recommendation to the Proxy Committee shall certify as to their compliance with this policy concurrently with the submission of their override recommendation. A form of such certification is attached as Appendix A hereto.

In addition, members of the Proxy Committee must notify INVESCO's Chief Compliance Officer, with impunity and without fear of retribution or retaliation, of any direct, indirect or perceived improper influence made by anyone within INVESCO or by an affiliated company's representatives with regard to how INVESCO should vote proxies. The Chief Compliance Officer will investigate the allegations and will report his or her findings to the INVESCO Risk Management Committee. In the event that it is determined that improper influence was made, the Risk Management Committee will determine the appropriate action to take which may include, but is not limited to, (1) notifying the affiliated company's Chief Executive Officer, its Management Committee or Board of Directors, (2) taking remedial action, if necessary, to correct the result of any improper influence where clients have been harmed, or (3) notifying the appropriate regulatory agencies of the improper influence and to fully

E-44

cooperate with these regulatory agencies as required. In all cases, the Proxy Committee shall not take into consideration the improper influence in determining how to vote proxies and will vote proxies solely in the best economic interest of clients.

Furthermore, members of the Proxy Committee must advise INVESCO's Chief Compliance Officer and fellow Committee members of any real or perceived conflicts of interest he or she may have with regard to how proxies are to be voted regarding certain companies (e.g., personal security ownership in a company, or personal or business relationships with participants in proxy contests, corporate directors or candidates for corporate directorships). After reviewing such conflict, upon advice from the Chief Compliance Officer, the Committee may require such Committee member to recuse himself or herself from participating in the discussions regarding the proxy vote item and from casting a vote regarding how INVESCO should vote such proxy.

PROXY POLICY APPLIES TO THE FOLLOWING:

INVESCO TRIMARK INVESTMENT MANAGEMENT INC.

PROXY VOTING

Policy Number: B-6 Effective Date: May 1, 2001 Revision Date: November 6, 2006

PURPOSE AND BACKGROUND

In its trusteeship and management of mutual funds, AIM Trimark acts as fiduciary to the unitholders and must act in their best interests.

APPLICATION

AIM Trimark will make every effort to exercise all voting rights with respect to securities held in the mutual funds that it manages in Canada or to which it provides sub-advisory services, including a Fund registered under and governed by the US Investment Company Act of 1940, as amended (the "US Funds") (collectively, the "Funds"). Proxies for the funds distributed by AIM Trimark Investments and managed by an affiliate or a third party (a "Sub-Advisor") will be voted in accordance with the Sub-Advisor's policy, unless the sub-advisory agreement provides otherwise.

The portfolio managers have responsibility for exercising all proxy votes and in doing so, for acting in the best interest of the Fund. Portfolio managers must vote proxies in accordance with the Guidelines, as amended from time to time, a copy of which is attached to this policy.

When a proxy is voted against management's recommendation, the portfolio manager will provide to the CIO the reasons in writing for any vote in opposition to management's recommendation. AIM Trimark may delegate to a third party the responsibility to vote proxies on behalf of all or certain Funds, in accordance with the Guidelines.

RECORDS MANAGEMENT

The Investment Department will endeavour to ensure that all proxies and notices are received from all issuers on a timely basis, and will maintain for all Funds

- A record of all proxies received;

- a record of votes cast;

- a copy of the reasons for voting against management; and for the US Funds

- the documents mentioned above; and

- a copy of any document created by AIM Trimark that was material to making a decision how to vote proxies on behalf of a US Fund and that memorializes the basis of that decision.

AIM Trimark has a dedicated Central Proxy Administrator who manages all proxy voting materials. Proxy voting circulars for all companies are received electronically through an external service provider. Circulars for North American companies and ADRs are generally also received in paper format.

Once a circular is received, the Administrator verifies that all shares and Funds affected are correctly listed. The Administrator then gives a copy of the proxy summary to each affected portfolio manager and maintains a tracking list to ensure that all proxies are voted within the prescribed deadlines.

E-47

Once voting information has been received from the portfolio managers, voting instructions are sent electronically to the service provider who then forwards the instructions to the appropriate proxy voting agent or transfer agent. The external service provider retains on behalf of AIM Trimark a record of the votes cast and agrees to provide AIM Trimark with a copy of proxy records promptly upon request. The service provider must make all documents available to AIM Trimark for a period of 6 years.

In the event that AIM Trimark ceases to use an external service provider, all documents would be maintained and preserved in an easily accessible place i) for a period of 2 years where AIM Trimark carries on business in Canada and ii) for a period of 3 years thereafter at the same location or at any other location.

REPORTING

The CIO will report on proxy voting to the Fund Boards on an annual basis with respect to all funds managed in Canada or distributed by AIM Trimark Investments and managed by a Sub-Advisor. The CIO will report on proxy voting to the Board of Directors of the US Funds as required from time to time.

In accordance with NI 81-106, proxy voting records for all Canadian mutual funds for years ending June 30th are posted on AIM Trimark's websites. The AIM Trimark Compliance department will review the proxy voting records held by AIM Trimark on an annual basis.

E-48

AIM TRIMARK INVESTMENTS

PROXY VOTING GUIDELINES (APRIL 17, 2006)

PURPOSE

The purpose of this document is to describe AIM Trimark's general guidelines for voting proxies received from companies held in AIM Trimark's Toronto-based funds. Proxy voting for the funds managed on behalf of AIM Trimark on a sub-advised basis (i.e. by other AMVESCAP business units or on a third party basis) are subject to the proxy voting policies & procedures of those other entities. As part of its regular due diligence, AIM Trimark will review the proxy voting policies & procedures of any new sub-advisors to ensure that they are appropriate in the circumstances.

INTRODUCTION

AIM Trimark has the fiduciary obligation to ensure that the long-term economic best interest of unitholders is the key consideration when voting proxies of portfolio companies.

As a general rule, AIM Trimark shall vote against any actions that would:

- reduce the rights or options of shareholders,

- reduce shareholder influence over the board of directors and management,

- reduce the alignment of interests between management and shareholders, or

- reduce the value of shareholders' investments.

At the same time, since AIM Trimark's Toronto-based portfolio managers follow an investment discipline that includes investing in companies that are believed to have strong management teams, the portfolio managers will generally support the management of companies in which they invest, and will accord proper weight to the positions of a company's board of directors. Therefore, in most circumstances, votes will be cast in accordance with the recommendations of the company's board of directors.

While AIM Trimark's proxy voting guidelines are stated below, the portfolio managers will take into consideration all relevant facts and circumstances (including country specific considerations), and retain the right to vote proxies as deemed appropriate.

These guidelines may be amended from time to time.

CONFLICTS OF INTEREST

When voting proxies, AIM Trimark's portfolio managers assess whether there are material conflicts of interest between AIM Trimark's interests and those of unitholders. A potential conflict of interest situation may include where AIM Trimark or an affiliate manages assets for, provides other financial services to, or otherwise has a material business relationship with, a company whose management is soliciting proxies, and failure to vote in favour of management of the company may harm AIM Trimark's relationship with the company. In all situations, the portfolio managers will not take AIM Trimark's relationship with the company into account, and will vote the proxies in the best interest of the unitholders. To the extent that a portfolio manager has any conflict of interest with respect to a company or an issue presented, that portfolio manager should abstain from voting on that company or issue. Portfolio managers are required to report to the Chief Investment Officer any such conflicts of interest and/or attempts by outside parties to improperly influence the voting process.

E-49

BOARDS OF DIRECTORS

We believe that a board that has at least a majority of independent directors is integral to good corporate governance. Unless there are restrictions specific to a company's home jurisdiction, key board committees, including audit and compensation committees, should be completely independent.

VOTING ON DIRECTOR NOMINEES IN UNCONTESTED ELECTIONS

Votes in an uncontested election of directors are evaluated on a CASE-BY-CASE basis, considering factors that may include:

- Long-term company performance relative to a market index,

- Composition of the board and key board committees,

- Nominee's attendance at board meetings,

- Nominee's time commitments as a result of serving on other company boards,

- Nominee's investments in the company,

- Whether the chairman is also serving as CEO, and

- Whether a retired CEO sits on the board.

VOTING ON DIRECTOR NOMINEES IN CONTESTED ELECTIONS

Votes in a contested election of directors are evaluated on a CASE-BY-CASE basis, considering factors that may include:

- Long-term financial performance of the target company relative to its industry,

- Management's track record,

- Background to the proxy contest,

- Qualifications of director nominees (both slates),

- Evaluation of what each side is offering shareholders as well as the likelihood that the proposed objectives and goals can be met, and

- Stock ownership positions.

MAJORITY THRESHOLD VOTING FOR DIRECTOR ELECTIONS

We will generally vote for proposals that require directors to be elected with an affirmative majority of votes cast unless the relevant portfolio manager believes that the company has adopted formal corporate governance principles that present a meaningful alternative to the majority voting standard and provide an adequate and timely response to both new nominees as well as incumbent nominees who fail to receive a majority of votes cast.

REIMBURSEMENT OF PROXY SOLICITATION EXPENSES

Decisions to provide reimbursement for dissidents waging a proxy contest are made on a CASE-BY-CASE basis.

SEPARATING CHAIRMAN AND CEO

Shareholder proposals to separate the chairman and CEO positions should be evaluated on a CASE-BY-CASE basis.

E-50

While we generally support these proposals, some companies have governance structures in place that can satisfactorily counterbalance a combined position. Voting decisions will take into account factors such as:

- Designated lead director, appointed from the ranks of the independent board members with clearly delineated duties;

- Majority of independent directors;

- All-independent key committees;

- Committee chairpersons nominated by the independent directors;

- CEO performance is reviewed annually by a committee of outside directors; and

- Established governance guidelines.

MAJORITY OF INDEPENDENT DIRECTORS

While we generally support shareholder proposals asking that a majority of directors be independent, each proposal should be evaluated on a case-by-case basis.

We generally vote for shareholder proposals that request that the board's audit, compensation, and/or nominating committees be composed exclusively of independent directors.

STOCK OWNERSHIP REQUIREMENTS

We believe that individual directors should be appropriately compensated and motivated to act in the best interests of shareholders. Share ownership by directors better aligns their interests with those of other shareholders. Therefore, we believe that meaningful share ownership by directors is in the best interest of the company.

We generally vote FOR proposals that require a certain percentage of a director's compensation to be in the form of common stock.

SIZE OF BOARDS OF DIRECTORS

We believe that the number of directors is important to ensuring the board's effectiveness in maximizing long-term shareholder value. The board must be large enough to allow it to adequately discharge its responsibilities, without being so large that it becomes cumbersome.

While we will prefer a board of no fewer than 5 and no more than16 members, each situation will be considered on a CASE-BY-CASE basis taking into consideration the specific company circumstances.

CLASSIFIED OR STAGGERED BOARDS

In a classified or staggered board, directors are typically elected in two or more "classes", serving terms greater than one year.

We prefer the annual election of all directors and will generally NOT SUPPORT proposals that provide for staggered terms for board members. We recognize that there may be jurisdictions where staggered terms for board members is common practice and, in such situations, we will review the proposals on a case-by-case basis.

DIRECTOR INDEMNIFICATION AND LIABILITY PROTECTION

We recognize that many individuals may be reluctant to serve as corporate directors if they were to be personally liable for all lawsuits and legal costs. As a result, limitations on directors' liability can benefit the corporation and its shareholders by helping to attract and retain qualified directors while providing recourse to shareholders on areas of misconduct by directors.

E-51

We generally vote for proposals that limit directors' liability and provide indemnification as long as the arrangements are limited to the director acting honestly and in good faith with a view to the best interests of the corporation and, in criminal matters, are limited to the director having reasonable grounds for believing the conduct was lawful.

AUDITORS

A strong audit process is a requirement for good corporate governance. A significant aspect of the audit process is a strong relationship with a knowledgeable and independent set of auditors.

RATIFICATION OF AUDITORS

We believe a company should limit its relationship with its auditors to the audit engagement, and certain closely related activities that do not, in the aggregate, raise an appearance of impaired independence.

We generally vote FOR the reappointment of the company's auditors unless:

- It is not clear that the auditors will be able to fulfill their function;

- There is reason to believe the auditors have rendered an opinion that is neither accurate nor indicative of the company's financial position; or

- The auditors have a significant professional or personal relationship with the issuer that compromises their independence.

DISCLOSURE OF AUDIT VS. NON-AUDIT FEES

Understanding the fees earned by the auditors is important for assessing auditor independence. Our support for the re-appointment of the auditors will take into consideration whether the management information circular contains adequate disclosure about the amount and nature of audit vs. non-audit fees.

There may be certain jurisdictions that do not currently require disclosure of audit vs. non-audit fees. In these circumstances, we will generally SUPPORT proposals that call for this disclosure.

COMPENSATION PROGRAMS

Appropriately designed equity-based compensation plans, approved by shareholders, can be an effective way to align the interests of long-term shareholders and the interests of management, employees and directors. Plans should not substantially dilute shareholders' ownership interests in the company, provide participants with excessive awards or have objectionable structural features. We will consider each compensation plan in its entirety (including all incentives, awards and other compensation) to determine if the plan provides the right incentives to managers and directors and is reasonable on the whole.

While we generally encourage companies to provide more transparent disclosure related to their compensation programs, the following are specific guidelines dealing with some of the more common features of these programs (features not specifically itemized below will be considered on a CASE-BY-CASE basis taking into consideration the general principles described above):

CASH COMPENSATION AND SEVERANCE PACKAGES

We will generally SUPPORT the board's discretion to determine and grant appropriate cash compensation and severance packages.

EQUITY BASED PLANS - DILUTION

We will generally vote AGAINST equity-based plans where the total dilution (including all equity-based plans) is excessive.

E-52

EMPLOYEE STOCK PURCHASE PLANS

We will generally vote FOR the use of employee stock purchase plans to increase company stock ownership by employees, provided that shares purchased under the plan are acquired for no less than 85% of their market value. It is recognized that country specific circumstances may exist (e.g. tax issues) that require proposals to be reviewed on a CASE-BY-CASE basis.

LOANS TO EMPLOYEES

We will vote AGAINST the corporation making loans to employees to allow employees to pay for stock or stock options. It is recognized that country specific circumstances may exist that require proposals to be reviewed on a CASE-BY-CASE basis.

STOCK OPTION PLANS - BOARD DISCRETION

We will vote AGAINST stock option plans that give the board broad discretion in setting the terms and conditions of the programs. Such programs should be submitted with detail and be reasonable in the circumstances regarding their cost, scope, frequency and schedule for exercising the options.

STOCK OPTION PLANS - INAPPROPRIATE FEATURES

We will generally vote AGAINST plans that have any of the following structural features:

- ability to re-price "underwater" options without shareholder approval,

- ability to issue options with an exercise price below the stock's current market price,

- ability to issue "reload" options, or

- automatic share replenishment ("evergreen") features.

STOCK OPTION PLANS - DIRECTOR ELIGIBILITY

While we prefer stock ownership by directors, we will SUPPORT stock option plans for directors as long as the terms and conditions of director options are clearly defined and are reasonable.

STOCK OPTION PLANS - REPRICING

We will vote FOR proposals to re-price options if there is a value-for-value (rather than a share-for-share) exchange.

STOCK OPTION PLANS - VESTING

We will vote AGAINST stock option plans that are 100% vested when granted.

STOCK OPTION PLANS - AUTHORIZED ALLOCATIONS

We will generally vote AGAINST stock option plans that authorize allocation of 25% or more of the available options to any one individual.

STOCK OPTION PLANS - CHANGE IN CONTROL PROVISIONS

We will vote AGAINST stock option plans with change in control provisions that allow option holders to receive more for their options than shareholders would receive for their shares.

CORPORATE MATTERS

We will review management proposals relating to changes to capital structure, reincorporation, restructuring and mergers & acquisitions on a case-by-case basis, taking into consideration the impact of the changes on corporate governance and shareholder rights, anticipated financial and operating benefits, portfolio manager views, level of dilution, and a company's industry and performance in terms of shareholder returns.

E-53

COMMON STOCK AUTHORIZATION

We will review proposals to increase the number of shares of common stock authorized for issue on a CASE-BY-CASE basis.

DUAL CLASS SHARE STRUCTURES

Dual class share structures involve a second class of common stock with either superior or inferior voting rights to those of another class of stock.

We will generally vote AGAINST proposals to create or extend dual class share structures where certain stockholders have superior or inferior voting rights to another class of stock.

STOCK SPLITS

We will vote FOR proposals to increase common share authorization for a stock split, provided that the increase in authorized shares would not result in excessive dilution given a company's industry and performance in terms of shareholder returns.

REVERSE STOCK SPLITS

We will vote FOR management proposals to implement a reverse stock split, provided that the reverse split does not result in an increase of authorized but unissued shares of more than 100% after giving effect to the shares needed for the reverse split.

SHARE REPURCHASE PROGRAMS

We will vote AGAINST proposals to institute open-market share repurchase plans if all shareholders do not participate on an equal basis.

REINCORPORATION

Reincorporation involves re-establishing the company in a different legal jurisdiction.

We will generally vote FOR proposals to reincorporate the company provided that the board and management have demonstrated sound financial or business reasons for the move. Proposals to reincorporate will NOT BE SUPPORTED if solely as part of an anti-takeover defense or as a way to limit directors' liability.

MERGERS & ACQUISITIONS

We will vote FOR merger & acquisition proposals that the relevant portfolio managers believe, based on their review of the materials:

- will result in financial and operating benefits,

- have a fair offer price,

- have favourable prospects for the combined companies, and

- will not have a negative impact on corporate governance or shareholder rights.

SOCIAL RESPONSIBILITY

We recognize that to effectively manage a corporation, directors and management must consider not only the interests of shareholders, but the interests of employees, customers, suppliers, and creditors, among others.

We believe that companies and their boards must give careful consideration to social responsibility issues in order to enhance long-term shareholder value.

We SUPPORT efforts by companies to develop policies and practices that consider social responsibility issues related to their businesses.

E-54

SHAREHOLDER PROPOSALS

Shareholder proposals can be extremely complex, and the impact on the interests of all stakeholders can rarely be anticipated with a high degree of confidence. As a result, shareholder proposals will be reviewed on a CASE-BY-CASE basis with consideration of factors such as:

- the proposal's impact on the company's short-term and long-term share value,

- its effect on the company's reputation,

- the economic effect of the proposal,

- industry and regional norms applicable to the company,

- the company's overall corporate governance provisions, and

- the reasonableness of the request.

We will generally SUPPORT shareholder proposals that require additional disclosure regarding corporate responsibility issues where the relevant portfolio manager believes:

- the company has failed to adequately address these issues with shareholders,

- there is information to suggest that a company follows procedures that are not in compliance with applicable regulations, or

- the company fails to provide a level of disclosure that is comparable to industry peers or generally accepted standards.

We will generally NOT SUPPORT shareholder proposals that place arbitrary or artificial constraints on the board, management or the company.

ORDINARY BUSINESS PRACTICES

We will generally SUPPORT the board's discretion regarding shareholder proposals that involve ordinary business practices.

PROTECTION OF SHAREHOLDER RIGHTS

We will generally vote FOR shareholder proposals that are designed to protect shareholder rights if the company's corporate governance standards indicate that such additional protections are warranted.

BARRIERS TO SHAREHOLDER ACTION

We will generally vote FOR proposals to lower barriers to shareholder action.

SHAREHOLDER RIGHTS PLANS

We will generally vote FOR proposals to subject shareholder rights plans to a shareholder vote.

OTHER

We will vote AGAINST any proposal where the proxy materials lack sufficient information upon which to base an informed decision.

We will vote AGAINST any proposals to authorize the company to conduct any other business that is not described in the proxy statement (including the authority to approve any further amendments to an otherwise approved resolution).

E-55

PORTFOLIO MANAGERS

PORTFOLIO MANAGER FUND HOLDINGS AND INFORMATION ON OTHER MANAGED ACCOUNTS

Invesco Aim's portfolio managers develop investment models which are used in connection with the management of certain AIM Funds as well as other mutual funds for which Invesco Aim or an affiliate acts as sub-advisor, other pooled investment vehicles that are not registered mutual funds, and other accounts managed for organizations and individuals. The following chart reflects the portfolio managers' investments in the Funds that they manage. The chart also reflects information regarding accounts other than the Funds for which each portfolio manager has day-to-day management responsibilities. Accounts are grouped into three categories: (i) mutual funds, (ii) other pooled investment vehicles, and (iii) other accounts. To the extent that any of these accounts pay advisory fees that are based on account performance ("performance-based fees"), information on those accounts is specifically broken out. In addition, any assets denominated in foreign currencies have been converted into U.S. Dollars using the exchange rates as of the applicable date.

The following information is as of March 31, 2008:

POTENTIAL CONFLICTS OF INTEREST

Actual or apparent conflicts of interest may arise when a portfolio manager has day-to-day management responsibilities with respect to more than one Fund or other account. More specifically, portfolio managers who manage multiple Funds and/or other accounts may be presented with one or more of the following potential conflicts:


(1) This column reflects investments in a Fund's shares owned directly by a portfolio manager or beneficially owned by a portfolio manager (as determined in accordance with Rule 16a-1(a)(2) under the Securities Exchange Act of 1934, as amended). A portfolio manager is presumed to be a beneficial owner of securities that are held by his or her immediate family members sharing the same household.

(2) These are accounts of individual investors for which Invesco Aim's affiliate, Invesco Aim Private Asset Management, Inc. ("IAPAM") provides investment advice. IAPAM offers separately managed accounts that are managed according to the investment models developed by Invesco Aim's portfolio managers and used in connection with the management of certain AIM Funds. IAPAM accounts may be invested in accordance with one or more of those investment models and investments held in those accounts are traded in accordance with the applicable models.

H-1

- The management of multiple Funds and/or other accounts may result in a portfolio manager devoting unequal time and attention to the management of each Fund and/or other account. The Advisor and each Sub-Advisor seek to manage such competing interests for the time and attention of portfolio managers by having portfolio managers focus on a particular investment discipline. Most other accounts managed by a portfolio manager are managed using the same investment models that are used in connection with the management of the Funds.

- If a portfolio manager identifies a limited investment opportunity which may be suitable for more than one Fund or other account, a Fund may not be able to take full advantage of that opportunity due to an allocation of filled purchase or sale orders across all eligible Funds and other accounts. To deal with these situations, the Advisor, each Sub-Advisor and the Funds have adopted procedures for allocating portfolio transactions across multiple accounts.

- The Advisor and each Sub-Advisor determine which broker to use to execute each order for securities transactions for the Funds, consistent with its duty to seek best execution of the transaction. However, for certain other accounts (such as mutual funds for which Invesco Aim or an affiliate acts as sub-advisor, other pooled investment vehicles that are not registered mutual funds, and other accounts managed for organizations and individuals), the Advisor and each Sub-Advisor may be limited by the client with respect to the selection of brokers or may be instructed to direct trades through a particular broker. In these cases, trades for a Fund in a particular security may be placed separately from, rather than aggregated with, such other accounts. Having separate transactions with respect to a security may temporarily affect the market price of the security or the execution of the transaction, or both, to the possible detriment of the Fund or other account(s) involved.

- Finally, the appearance of a conflict of interest may arise where the Advisor or Sub-Advisor has an incentive, such as a performance-based management fee, which relates to the management of one Fund or account but not all Funds and accounts for which a portfolio manager has day-to-day management responsibilities.

The Advisor, each Sub-Advisor, and the Funds have adopted certain compliance procedures which are designed to address these types of conflicts. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.

DESCRIPTION OF COMPENSATION STRUCTURE

For the Advisor and each affiliated Sub-Advisor

The Advisor and each Sub-Advisor seek to maintain a compensation program that is competitively positioned to attract and retain high-caliber investment professionals. Portfolio managers receive a base salary, an incentive bonus opportunity, and an equity compensation opportunity. Portfolio manager compensation is reviewed and may be modified each year as appropriate to reflect changes in the market, as well as to adjust the factors used to determine bonuses to promote competitive fund performance. The Advisor and each Sub-Advisor evaluate competitive market compensation by reviewing compensation survey results conducted by an independent third party of investment industry compensation. Each portfolio manager's compensation consists of the following three elements:

Base Salary. Each portfolio manager is paid a base salary. In setting the base salary, the Advisor and each Sub-Advisor's intention is to be competitive in light of the particular portfolio manager's experience and responsibilities.

Annual Bonus. The portfolio managers are eligible, along with other employees of the Advisor and each Sub-Advisor, to participate in a discretionary year-end bonus pool. The Compensation Committee of Invesco reviews and approves the amount of the bonus pool available for the Advisor and each of the Sub-Advisor's investment centers. The Compensation Committee considers investment

H-2

performance and financial results in its review. In addition, while having no direct impact on individual bonuses, assets under management are considered when determining the starting bonus funding levels. Each portfolio manager is eligible to receive an annual cash bonus which is based on quantitative (i.e. investment performance) and non-quantitative factors (which may include, but are not limited to, individual performance, risk management and teamwork).

Each portfolio manager's compensation is linked to the pre-tax investment performance of the funds/accounts managed by the portfolio manager as described in Table 1 below.

Invesco Institutional - Invesco Real Estate U.S.'s bonus is based on net operating profits of Invesco Institutional - Invesco Real Estate U.S.

Invesco Senior Secured's bonus is based on annual measures of equity return and standard tests of collateralization performance.

High investment performance (against applicable peer group) would deliver compensation generally associated with top pay in the industry (determined by reference to the third-party provided compensation survey information) and poor investment performance (versus applicable peer group) would result in low bonus compared to the applicable peer group or no bonus at all. These decisions are reviewed and approved collectively by senior leadership which has responsibility for executing the compensation approach across the organization.


(3) Rolling time periods based on calendar year end.

H-3

Equity-Based Compensation. Portfolio managers may be awarded options to purchase common shares and/or granted restricted shares of Invesco stock from pools determined from time to time by the Compensation Committee of Invesco's Board of Directors. Awards of equity-based compensation typically vest over time, so as to create incentives to retain key talent.

Portfolio managers also participate in benefit plans and programs available generally to all employees.

MIRIAM CALDERON, INDIVIDUALLY AND ON BEHALF OF ALL OTHERS SIMILARLY SITUATED, V. AVZ, INC., AMVESCAP RETIREMENT, INC., AMVESCAP NATIONAL TRUST COMPANY, INVESCO FUNDS GROUP, INC., AMVESCAP, ROBERT F. MCCULLOUGH, GORDON NEBEKER, JEFFREY G. CALLAHAN, AND RAYMOND R. CUNNINGHAM, in the MDL Court (Case No. 1:04-MD-15864-FPS), filed on September 29, 2004.

The plaintiffs in this lawsuit are seeking: declaratory judgment; restoration of losses suffered by the plan; disgorgement of profits; imposition of a constructive trust; injunctive relief; compensatory damages; costs and attorneys' fees; and equitable restitution.

On March 1, 2006, the MDL Court entered orders on Defendants' Motions to dismiss in the derivative (Essenmacher) and class action (Lepera) lawsuits. The MDL Court dismissed all derivative causes of action in the Essenmacher lawsuit but two: (i) the excessive fee claim under Section 36(b) of the Investment Company Act of 1940 (the "1940 Act"); and (ii) the "control person liability" claim under Section 48 of the 1940 Act. The MDL Court dismissed all claims asserted in the Lepera class action lawsuit but three: (i) the securities fraud claims under Section 10(b) of the Securities Exchange Act of 1934; (ii) the excessive fee claim under Section 36(b) of the 1940 Act (which survived only insofar as plaintiffs seek recovery of fees associated with the assets involved in market timing); and (iii) the "control person liability" claim under Section 48 of the 1940 Act. On June 14, 2006, the MDL Court entered an order dismissing the Section 48 claim in the derivative (Essenmacher) lawsuit. Based on the MDL Court's March 1, 2006 and June 14, 2006 orders, all claims asserted against the Funds that have been transferred to the MDL Court have been dismissed, although certain Funds remain nominal defendants in the derivative (Essenmacher) lawsuit. Defendants filed their Original Answer in the class action (Lepera) lawsuit on March 31, 2006. The MDL Court has indefinitely deferred Defendants' obligation to answer the derivative (Essenmacher) lawsuit. The Plaintiffs in the class action (Lepera) lawsuit stipulated that their claims against Invesco Aim, Invesco Aim Distributors and Invesco Aim Investment Services, Inc. ("Invesco Aim Investment Services") are based solely on successor liability for alleged timing in the AIM Funds formerly advised by IFG and that they are not making any claims based on alleged timing in the other AIM Funds. Based upon this stipulation, Invesco Aim withdrew its pending Motion to Dismiss the claims against Invesco Aim, Invesco Aim Distributors and Invesco Aim Investment Services. On July 3, 2007, the Defendants filed an Omnibus Motion to Dismiss in both the class action (Lepera) and derivative (Essenmacher) lawsuits based on Plaintiffs' lack of standing to sue for injuries to funds the Plaintiffs do not own. On October 19, 2007, Judge Motz for the MDL Court denied the Defendants' Motion to Dismiss.

On September 15, 2006, Judge Motz for the MDL Court granted the Defendants' motion to dismiss the ERISA (Calderon) lawsuit and dismissed such lawsuit. The Plaintiff appealed this decision. On June 16, 2008, the Fourth Court of Appeals reversed the dismissal and remanded this lawsuit back to the MDL Court for further proceedings.

APPENDIX P-2

PENDING LITIGATION ALLEGING INADEQUATELY EMPLOYED FAIR VALUE PRICING

The following civil class action lawsuits involve, depending on the lawsuit, one or more AIM Funds, IFG and/or Invesco Aim and allege that the defendants inadequately employed fair value pricing. These lawsuits either have been served or have had service of process waived.

T.K. PARTHASARATHY, EDMUND WOODBURY, STUART ALLEN SMITH AND SHARON SMITH, INDIVIDUALLY AND ON BEHALF OF ALL OTHERS SIMILARLY SITUATED, V. T. ROWE PRICE INTERNATIONAL FUNDS, INC., T. ROWE PRICE INTERNATIONAL, INC., ARTISAN FUNDS, INC., ARTISAN PARTNERS LIMITED PARTNERSHIP, AIM INTERNATIONAL FUNDS,
INC. AND AIM ADVISORS, INC., in the Third Judicial Circuit Court for Madison County, Illinois (Case No. 2003-L-001253), filed on September 23, 2003. This claim alleges: common law breach of duty and common law negligence and gross negligence. The plaintiffs in these cases are seeking:
compensatory and punitive damages; interest; and attorneys' fees and costs. The Third Judicial Circuit Court for Madison County, Illinois has issued an order severing the claims of plaintiff Parthasarathy from the claims of the other plaintiffs against Invesco Aim and other defendants. As a result, Invesco Aim is a defendant in the following severed action: EDMUND WOODBURY, STUART ALLEN SMITH and SHARON SMITH, Individually and On Behalf of All Others Similarly Situated, v. AIM INTERNATIONAL FUNDS, INC., ET AL., in the Third Judicial Circuit Court for Madison County, Illinois (Case No. 03-L-1253A). The claims made by Plaintiffs and the relief sought in the Woodbury lawsuit are identical to those in the Parthasarathy lawsuit. This case has been through various procedural steps, including complete dismissal and appeals. The parties were contesting whether the proper venue for this action is the Federal District Court or the Illinois State Court. On July 17, 2007, the Federal District Court ordered this case remanded back to Illinois State Court. On January 1, 2008, the Illinois State Court denied defendants' Motion to Dismiss. Pursuant to a settlement agreement, Plaintiffs filed a Motion to Dismiss with prejudice, which was granted on May 6, 2008.

JOHN BILSKI, INDIVIDUALLY AND ON BEHALF OF ALL OTHERS SIMILARLY SITUATED, V. AIM INTERNATIONAL FUNDS, INC., AIM ADVISORS, INC., INVESCO INTERNATIONAL FUNDS, INC., INVESCO FUNDS GROUP, INC., T. ROWE PRICE INTERNATIONAL FUNDS,
INC. AND T. ROWE PRICE INTERNATIONAL, INC., in the United States District Court, Southern District of Illinois (East St. Louis) (Case No. 03-772), filed on November 19, 2003. This claim alleges: violations of Sections 36(a) and 36(b) of the Investment Company Act of 1940; common law breach of duty; and common law negligence and gross negligence. The plaintiff in this case is seeking: compensatory and punitive damages; interest; and attorneys' fees and costs. This lawsuit has been transferred to the MDL Court by order of the United States District Court, Southern District of Illinois (East St. Louis).

Item 25. Indemnification

Indemnification provisions for officers, trustees, and employees of the Registrant are set forth in Article VIII of the Registrant's Amended and Restated Agreement and Declaration of Trust and Article VIII of its Amended and Restated Bylaws, and are hereby incorporated by reference. See Item 23(a) and (b) above. Under the Amended and Restated Agreement and Declaration of Trust, effective as of September 14, 2005, as amended, (i) Trustees or officers, when acting in such capacity, shall not be personally liable for any act, omission or obligation of the Registrant or any Trustee or officer except by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office with the Trust; (ii) every Trustee, officer, employee or agent of the Registrant shall be indemnified to the fullest extent permitted under the Delaware Statutory Trust act, the Registrant's Bylaws and other applicable law; (iii) in case any shareholder or former shareholder of the Registrant shall be held to be personally liable solely by reason of his being or having been a shareholder of the Registrant or any portfolio or class and not because of his acts or omissions or for some other reason, the shareholder or former shareholder (or his heirs, executors, administrators or other legal representatives, or, in the case of a corporation or other entity, its corporate or general successor) shall be entitled, out of the assets belonging to the applicable portfolio (or allocable to the applicable class), to be held harmless from and indemnified against all loss and expense arising from such liability in accordance with the Bylaws and applicable law. The Registrant, on behalf of the affected portfolio (or class), shall upon request by the shareholder, assume the defense of any such claim made against the shareholder for any act or obligation of that portfolio (or class).

The Registrant and other investment companies and their respective officers and trustees are insured under a joint Mutual Fund Directors and Officers Liability Policy, issued by ICI Mutual Insurance Company and certain other domestic insurers, with limits up to $60,000,000 (plus an additional $20,000,000 limit that applies to independent directors/trustees only).

Section 16 of the Master Investment Advisory Agreement between the Registrant and Invesco Aim provides that in the absence of willful misfeasance, bad faith, gross negligence or reckless disregard of obligations or duties hereunder on the part of Invesco Aim or any of its officers, directors or employees, that Invesco Aim shall not be subject to liability to the Registrant or to any series of the Registrant, or to any shareholder of any series of the Registrant for any act or omission in the course of, or connected with, rendering services hereunder or for any losses that may be sustained in the purchase, holding or sale of any security. Any liability of Invesco Aim to any series of the Registrant shall not automatically impart liability on the part of Invesco Aim to any other series of the Registrant. No series of the Registrant shall be liable for the obligations of any other series of the Registrant.

Section 9 of the Master Intergroup Sub-Advisory Contract for Mutual Funds (the "Sub-Advisory Contract") between Invesco Aim Advisors, Inc., on behalf of Registrant, and each of Invesco Asset Management Deutschland GmbH, Invesco Asset Management Ltd., Invesco Asset Management (Japan) Limited, Invesco Australia Limited, Invesco Global Asset Management (N.A.), Inc., Invesco Hong Kong Limited, Invesco Institutional (N.A.), Inc., Invesco Senior Secured Management, Inc. and AIM Funds Management Inc. (each a "Sub-Advisor", collectively the "Sub-Advisors") provides that the Sub-Advisor shall not be liable for any costs or liabilities arising from any error of judgment or mistake of law or any loss suffered by any series of the Registrant or the Registrant in connection with the matters to which the Sub-Advisory Contract relates except a loss resulting from willful misfeasance, bad faith or gross negligence on the part of the Sub-Advisor in the performance by the Sub-Advisor of its duties or from reckless disregard by the Sub-Advisor of its obligations and duties under the Sub-Advisory Contract.

C-8

Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the "Act") may be permitted to trustees, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a trustee, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such trustee, officer or controlling person in connection with the shares being registered hereby, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

If and to the extent requested by the Advisor, each Sub-Advisor shall provide investment advice to one or more of the Funds and the Advisor with respect to all or a portion of the investments of such Fund(s) or with respect to various investment techniques, and in connection with such advice shall furnish such Fund(s) and the Advisor with such factual information, research reports and investment recommendations as the Advisor may reasonably require.

1

(b) Order Execution. If and to the extent requested by the Advisor, each Sub-Advisor shall place orders for the purchase and sale of portfolio securities or other investments for one or more of the Funds. In so doing, each Sub-Advisor agrees that it shall comply with paragraph 3 below.

(c) Discretionary Investment Management. If and to the extent requested by the Advisor, each Sub-Advisor shall, subject to the supervision of the Trust's Board of Trustees (the "Board") and the Advisor, manage all or a portion of the investments of one or more of the Funds in accordance with the investment objectives, policies and limitations provided in the Trust's Registration Statement and such other limitations as the Trust or the Advisor may impose with respect to such Fund(s) by notice to the applicable Sub-Advisor(s) and otherwise in accordance with paragraph 5 below. With respect to the portion of the investments of a Fund under its management, each Sub-Advisor is authorized to:
(i) make investment decisions on behalf of the Fund with regard to any stock, bond, other security or investment instrument, including but not limited to foreign currencies, futures, options and other derivatives, and with regard to borrowing money; (ii) place orders for the purchase and sale of securities or other investment instruments with such brokers and dealers as the Sub-Advisor may select; and (iii) upon the request of the Advisor, provide additional investment management services to the Fund, including but not limited to managing the Fund's cash and cash equivalents and lending securities on behalf of the Fund. In selecting brokers or dealers to execute trades for the Funds, each Sub-Advisor will comply with its written policies and procedures regarding brokerage and trading, which policies and procedures shall have been approved by the Board. All discretionary investment management and any other activities of each Sub-Advisor shall at all times be subject to the control and direction of the Advisor and the Board.

3. Broker-Dealer Relationships. Each Sub-Advisor agrees that, in placing orders with brokers and dealers, it will attempt to obtain the best net result in terms of price and execution. Consistent with this obligation, each Sub-Advisor may, in its discretion, purchase and sell portfolio securities from and to brokers and dealers who sell shares of the Funds or provide the Funds, the Advisor's other clients, or a Sub-Advisor's other clients with research, analysis, advice and similar services. Each Sub-Advisor may pay to brokers and dealers, in return for such research and analysis, a higher commission or spread than may be charged by other brokers and dealers, subject to such Sub-Advisor determining in good faith that such commission or spread is reasonable in terms either of the particular transaction or of the overall responsibility of the Advisor and such Sub-Advisor to the Funds and their other clients and that the total commissions or spreads paid by each Fund will be reasonable in relation to the benefits to the Fund over the long term. In no instance will portfolio securities be purchased from or sold to a Sub-Advisor, or any affiliated person thereof, except in accordance with the applicable securities laws and the rules and regulations thereunder and any exemptive orders currently in effect. Whenever a Sub-Advisor simultaneously places orders to purchase or sell the same security on behalf of a Fund and one or more other accounts advised by such Sub-Advisor, such orders will be allocated as to price and amount among all such accounts in a manner believed to be equitable to each account.

4. Books and Records. Each Sub-Advisor will maintain all required books and records with respect to the securities transactions of the Funds, and will furnish the Board and the Advisor with such periodic and special reports as the Board or the Advisor reasonably may request. Each Sub-Advisor hereby agrees that all records which it maintains for the Advisor are the property of the Advisor, and agrees to preserve for the periods prescribed by applicable law any records which it maintains for the Advisor and which are required to be maintained, and further agrees to surrender promptly to the Advisor any records which it maintains for the Advisor upon request by the Advisor.

5. Further Duties.

(a) In all matters relating to the performance of this Contract, each Sub-Advisor will act in conformity with the Agreement and Declaration of Trust, By-Laws and Registration Statement of the Trust and with the instructions and directions of the Advisor and the Board and will comply with the requirements of the 1940 Act, the rules, regulations, exemptive orders and no-action positions thereunder, and all other applicable laws and regulations.

(b) Each Sub-Advisor shall maintain compliance procedures for the Funds that it and the Advisor reasonably believe are adequate to ensure compliance with the federal securities laws (as

2

defined in Rule 38a-1 of the 1940 Act) and the investment objective(s) and policies as stated in the Funds' prospectuses and statements of additional information. Each Sub-Advisor at its expense will provide the Advisor or the Trust's Chief Compliance Officer with such compliance reports relating to its duties under this Contract as may be requested from time to time. Notwithstanding the foregoing, each Sub-Advisor will promptly report to the Advisor any material violations of the federal securities laws (as defined in Rule 38a-1 of the 1940 Act) that it is or should be aware of or of any material violation of the Sub-Advisor's compliance policies and procedures that pertain to the Funds.

(c) Each Sub-Advisor at its expense will make available to the Board and the Advisor at reasonable times its portfolio managers and other appropriate personnel, either in person or, at the mutual convenience of the Advisor and the Sub-Advisor, by telephone, in order to review the investment policies, performance and other investment related information regarding the Funds and to consult with the Board and the Advisor regarding the Funds' investment affairs, including economic, statistical and investment matters related to the Sub-Advisor's duties hereunder, and will provide periodic reports to the Advisor relating to the investment strategies it employs. Each Sub-Advisor and its personnel shall also cooperate fully with counsel and auditors for, and the Chief Compliance Officer of, the Advisor and the Trust.

(d) Each Sub-Advisor will assist in the fair valuation of portfolio securities held by the Funds. The Sub-Advisor will use its reasonable efforts to provide, based upon its own expertise, and to arrange with parties independent of the Sub-Advisor such as broker-dealers for the provision of, valuation information or prices for securities for which prices are deemed by the Advisor or the Trust's administrator not to be readily available in the ordinary course of business from an automated pricing service. In addition, each Sub-Advisor will assist the Funds and their agents in determining whether prices obtained for valuation purposes accurately reflect market price information relating to the assets of the Funds at such times as the Advisor shall reasonably request, including but not limited to, the hours after the close of a securities market and prior to the daily determination of a Fund's net asset value per share.

(e) Each Sub-Advisor represents and warrants that it has adopted a code of ethics meeting the requirements of Rule 17j-1 under the 1940 Act and the requirements of Rule 204A-1 under the Advisors Act and has provided the Advisor and the Board a copy of such code of ethics, together with evidence of its adoption, and will promptly provide copies of any changes thereto, together with evidence of their adoption. Upon request of the Advisor, but in any event no less frequently than annually, each Sub-Advisor will supply the Advisor a written report that (A) describes any issues arising under the code of ethics or procedures since the Sub-Advisor's last report, including but not limited to material violations of the code of ethics or procedures and sanctions imposed in response to the material violations; and (B) certifies that the procedures contained in the Sub-Advisor's code of ethics are reasonably designed to prevent "access persons" from violating the code of ethics.

(f) Upon request of the Advisor, each Sub-Advisor will review draft reports to shareholders and other documents provided or available to it and provide comments on a timely basis. In addition, each Sub-Advisor and each officer and portfolio manager thereof designated by the Advisor will provide on a timely basis such certifications or sub-certifications as the Advisor may reasonably request in order to support and facilitate certifications required to be provided by the Trust's Principal Executive Officer and Principal Financial Officer and will adopt such disclosure controls and procedures in support of the disclosure controls and procedures adopted by the Trust as the Advisor, on behalf of the Trust, deems are reasonably necessary.

(g) Unless otherwise directed by the Advisor or the Board, each Sub-Advisor will vote all proxies received in accordance with the Advisor's proxy voting policy or, if the Sub-Advisor has a proxy voting policy approved by the Board, the Sub-Advisor's proxy voting policy. Each Sub-Advisor shall maintain and shall forward to the Funds or their designated agent such proxy voting information as is necessary for the Funds to timely file proxy voting results in accordance with Rule 30b1-4 of the 1940 Act.

(h) Each Sub-Advisor shall provide the Funds' custodian on each business day with information relating to all transactions concerning the assets of the Funds and shall provide the Advisor with such information upon request of the Advisor.

6. Services Not Exclusive. The services furnished by each Sub-Advisor hereunder are not to be deemed exclusive and such Sub-Advisor shall be free to furnish similar services to others so long as its services under this Contract are not impaired thereby. Nothing in this Contract shall limit or restrict the right of any director, officer or employee of a Sub-Advisor, who may also be a Trustee, officer or employee of the Trust, to engage in any other business or to devote his or her time and attention in part to the management or other aspects of any other business, whether of a similar nature or a dissimilar nature.

7. Use of Subsidiaries and Affiliates. Each Sub-Advisor may perform any or all of the services contemplated hereunder, including but not limited to providing investment advice to the Funds pursuant to paragraph 2(a) above and placing orders for the purchase and sale of portfolio securities or other investments for the Funds pursuant to paragraph 2(b) above, directly or through such of its subsidiaries or other affiliates, including each of the other Sub-Advisors, as such Sub-Advisor shall determine; provided, however, that performance of such services through such subsidiaries or other affiliates shall have been approved, when required by the 1940 Act, by (i) a vote of a majority of the independent Trustees who are not parties to this Contract or "interested persons" (as defined in the 1940 Act) of a party to this Contract, other than as Board members ("Independent Trustees"), cast in person at a meeting called for the purpose of voting on such approval, and/or (ii) a vote of a majority of that Fund's outstanding voting securities.

8. Compensation.

(a) The only fees payable to the Sub-Advisors under this Contract are for providing discretionary investment management services pursuant to paragraph 2(c) above. For such services, the Advisor will pay each Sub-Advisor a fee, computed daily and paid monthly, equal to (i) 40% of the monthly compensation that the Advisor receives from the Trust pursuant to its advisory agreement with the Trust, multiplied by (ii) the fraction equal to the net assets of such Fund as to which the Sub-Advisor shall have provided discretionary investment management services pursuant to paragraph 2(c) above for that month divided by the net assets of such Fund for that month. This fee shall be payable on or before the last business day of the next succeeding calendar month. This fee shall be reduced to reflect contractual or voluntary fee waivers or expense limitations by the Advisor, if any, in effect from time to time as set forth in paragraph 9 below. In no event shall the aggregate monthly fees paid to the Sub-Advisors under this Contract exceed 40% of the monthly compensation that the Advisor receives from the Trust pursuant to its advisory agreement with the Trust, as reduced to reflect contractual or voluntary fee waivers or expense limitations by the Advisor, if any.

(b) If this Contract becomes effective or terminates before the end of any month, the fees for the period from the effective date to the end of the month or from the beginning of such month to the date of termination, as the case may be, shall be prorated according to the proportion which such period bears to the full month in which such effectiveness or termination occurs.

(c) If a Sub-Advisor provides the services under paragraph 2(c) above to a Fund for a period that is less than a full month, the fees for such period shall be prorated according to the proportion which such period bears to the applicable full month.

9. Fee Waivers and Expense Limitations. If, for any fiscal year of a Fund, the amount of the advisory fee which such Fund would otherwise be obligated to pay to the Advisor is reduced because of contractual or voluntary fee waivers or expense limitations by the Advisor, the fee payable to each Sub-Advisor pursuant to paragraph 8 above shall be reduced proportionately; and to the extent that the Advisor reimburses the Fund as a result of such expense limitations, such Sub-Advisor shall reimburse the Advisor that proportion of such reimbursement payments which the fee payable to each Sub-Advisor pursuant to paragraph 8 above bears to the advisory fee under this Contract.

10. Limitation of Liability of Sub-Advisor and Indemnification. No Sub-Advisor shall be liable for any costs or liabilities arising from any error of judgment or mistake of law or any loss suffered by a Fund or the Trust in connection with the matters to which this Contract relates except a loss resulting from willful misfeasance, bad faith or gross negligence on the part of such Sub-Advisor in the performance by such

4

Sub-Advisor of its duties or from reckless disregard by such Sub-Advisor of its obligations and duties under this Contract. Any person, even though also an officer, partner, employee, or agent of a Sub-Advisor, who may be or become a Trustee, officer, employee or agent of the Trust, shall be deemed, when rendering services to a Fund or the Trust or acting with respect to any business of a Fund or the Trust, to be rendering such service to or acting solely for the Fund or the Trust and not as an officer, partner, employee, or agent or one under the control or direction of such Sub-Advisor even though paid by it.

11. Duration and Termination.

(a) This Contract shall become effective with respect to each Sub-Advisor upon the later of the date hereabove written and the date that such Sub-Advisor is registered with the SEC as an investment advisor under the Advisors Act, if a Sub-Advisor is not so registered as of the date hereabove written; provided, however, that this Contract shall not take effect with respect to any Fund unless it has first been approved (i) by a vote of a majority of the Independent Trustees, cast in person at a meeting called for the purpose of voting on such approval, and (ii) by vote of a majority of that Fund's outstanding voting securities, when required by the 1940 Act.

(b) Unless sooner terminated as provided herein, this Contract shall continue in force and effect until June 30, 2009. Thereafter, if not terminated, with respect to each Fund, this Contract shall continue automatically for successive periods not to exceed twelve months each, provided that such continuance is specifically approved at least annually (i) by a vote of a majority of the Independent Trustees, cast in person at a meeting called for the purpose of voting on such approval, and (ii) by the Board or by vote of a majority of the outstanding voting securities of that Fund.

(c) Notwithstanding the foregoing, with respect to any Fund(s) or any Sub-Advisor(s), this Contract may be terminated at any time, without the payment of any penalty, (i) by vote of the Board or by a vote of a majority of the outstanding voting securities of such Fund(s) on sixty days' written notice to such Sub-Advisor(s); or (ii) by the Advisor on sixty days' written notice to such Sub-Advisor(s); or (iii) by a Sub-Advisor on sixty days' written notice to the Trust. Should this Contract be terminated with respect to a Sub-Advisor, the Advisor shall assume the duties and responsibilities of such Sub-Advisor unless and until the Advisor appoints another Sub-Advisor to perform such duties and responsibilities. Termination of this Contract with respect to one or more Fund(s) or Sub-Advisor(s) shall not affect the continued effectiveness of this Contract with respect to any remaining Fund(s) or Sub-Advisor(s). This Contract will automatically terminate in the event of its assignment.

12. Amendment. No provision of this Contract may be changed, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against which enforcement of the change, waiver, discharge or termination is sought, and, when required by the 1940 Act, no amendment of this Contract shall be effective until approved by vote of a majority of the Fund's outstanding voting securities.

13. Notices. Any notices under this Contract shall be in writing, addressed and delivered, telecopied or mailed postage paid, to the other party entitled to receipt thereof at such address as such party may designate for the receipt of such notice. Until further notice to the other party, it is agreed that the address of the Trust and the Advisor shall be 11 Greenway Plaza, Suite 100, Houston, Texas 77046-1173. Until further notice to the other party, it is agreed that the address of each Sub-Advisor shall be set forth in Exhibit B attached hereto.

14. Governing Law. This Contract shall be construed in accordance with the laws of the State of Texas and the 1940 Act. To the extent that the applicable laws of the State of Texas conflict with the applicable provisions of the 1940 Act, the latter shall control.

15. Multiple Sub-Advisory Agreements. This Contract has been signed by multiple parties; namely the Advisor, on one hand, and each Sub-Advisor, on the other. The parties have signed one document for administrative convenience to avoid a multiplicity of documents. It is understood and agreed that this document shall constitute a separate sub-advisory agreement between the Advisor and each Sub-Advisor

5

with respect to each Fund, as if the Advisor and such Sub-Advisor had executed a separate sub-advisory agreement naming such Sub-Advisor as a sub-Advisor to each Fund. With respect to any one Sub-Advisor, (i) references in this Contract to "a Sub-Advisor" or to "each Sub-Advisor" shall be deemed to refer only to such Sub-Advisor, and (ii) the term "this Contract" shall be construed according to the foregoing provisions.

16. Miscellaneous. The captions in this Contract are included for convenience of reference only and in no way define or delimit any of the provisions hereof or otherwise affect their construction or effect. If any provision of this Contract shall be held or made invalid by a court decision, statute, rule or otherwise, the remainder of this Contract shall not be affected thereby. This Contract shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors. Any question of interpretation of any term or provision of this Contract having a counterpart in or otherwise derived from a term or provision of the 1940 Act or the Advisors Act shall be resolved by reference to such term or provision of the 1940 Act or the Advisors Act and to interpretations thereof, if any, by the United States Courts or in the absence of any controlling decision of any such court, by rules, regulations or orders of the SEC issued pursuant to said Acts. In addition, where the effect of a requirement of the 1940 Act or the Advisors Act reflected in any provision of the Contract is revised by rule, regulation or order of the SEC, such provision shall be deemed to incorporate the effect of such rule, regulation or order.

IN WITNESS WHEREOF, the parties hereto have caused this Contract to be executed by their officers designated as of the day and year first above written.

(SECURITIES LENDING ADMINISTRATIVE FEE WAIVER)

This Third Amended and Restated Memorandum of Agreement is entered into as of the dates indicated on Exhibit "A" between AIM Counselor Series Trust, AIM Equity Funds, AIM Funds Group, AIM Growth Series, AIM International Mutual Funds, AIM Investment Funds, AIM Investment Securities Funds, AIM Sector Funds, AIM Tax-Exempt Funds, AIM Treasurer's Series Trust, AIM Variable Insurance Funds and Short-Term Investments Trust (each a "Fund" and collectively, the "Funds"), on behalf of the portfolios listed on Exhibit "A" to this Memorandum of Agreement (the "Portfolios"), and Invesco Aim Advisors, Inc. ("Invesco Aim"). This Memorandum of Agreement restates the Memorandum of Agreement previously in effect prior to July 1, 2007 and entered into as of the effective dates indicated on Exhibit "A" between AIM Counselor Series Trust, AIM Equity Funds, AIM Funds Group, AIM Growth Series, AIM International Mutual Funds, AIM Investment Funds, AIM Investment Securities Funds, AIM Sector Funds, AIM Stock Funds, AIM Summit Fund, AIM Tax-Exempt Funds, AIM Variable Insurance Funds, AIM Treasurer's Series Trust, Short-Term Investments Trust and Tax-Free Investments Trust, on behalf of the portfolios and Invesco Aim.

For and in consideration of the mutual terms and agreements set forth herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Funds and Invesco Aim agree as follows:

1. Each Fund, for itself and its Portfolios, and Invesco Aim agree that until the expiration date, if any, of the commitment set forth on the attached Exhibit "A" occurs, as such Exhibit "A" is amended from time to time, Invesco Aim has agreed that it will not charge any administrative fee under each Portfolio's advisory agreement in connection with securities lending activities without prior approval from the Portfolio's Board (such agreement is referred to as the "Waiver").

2. Neither a Fund nor Invesco Aim may remove or amend the Waiver to a Fund's detriment prior to requesting and receiving the approval of the Portfolio's Board to remove or amend the Waiver. Invesco Aim will not have any right to reimbursement of any amount so waived.

Unless a Fund, by vote of its Board of Trustees terminates the Waiver, or a Fund and Invesco Aim are unable to reach an agreement on the amount of the Waiver to which the Fund and Invesco Aim desire to be bound, the Waiver will continue indefinitely with respect to such Fund. Exhibit "A" will be amended to reflect the new date through which a Fund and Invesco Aim agree to be bound.

Nothing in this Memorandum of Agreement is intended to affect any other memorandum of agreement executed by any Fund or Invesco Aim with respect to any other fee waivers, expense reimbursements and/or expense limitations.


IN WITNESS WHEREOF, each Fund, on behalf of itself and its Portfolios listed in Exhibit "A" to this Memorandum of Agreement, and Invesco Aim have entered into this Memorandum of Agreement as of the dates indicated on Exhibit "A".

MEMORANDUM OF AGREEMENT
(EXPENSE LIMITATIONS)

This Memorandum of Agreement is entered into as of the Effective Date on the attached exhibits (the "Exhibits"), between AIM Counselor Series Trust, AIM Equity Funds, AIM Growth Series, AIM Investment Funds, AIM Investment Securities Funds, AIM Sector Funds, AIM Tax-Exempt Funds, AIM Variable Insurance Funds and Short-Term Investments Trust (each a "Trust" or, collectively, the "Trusts"), on behalf of the funds listed on the Exhibits to this Memorandum of Agreement (the "Funds"), and Invesco Aim Advisors, Inc. ("Invesco Aim"). Invesco Aim shall and hereby agrees to waive fees or reimburse expenses of each Fund, on behalf of its respective classes as applicable, severally and not jointly, as indicated in the attached Exhibits.

For and in consideration of the mutual terms and agreements set forth herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Trusts and Invesco Aim agree as follows:

For the Contractual Limits (listed in Exhibits A - D), the Trusts and Invesco Aim agree until at least the expiration date set forth on the attached Exhibits A - D (the "Expiration Date") that Invesco Aim will waive its fees or reimburse expenses to the extent that expenses of a class of a Fund (excluding
(i) interest; (ii) taxes; (iii) dividend expense on short sales; (iv) extraordinary items; (v) expenses related to a merger or reorganization, as approved by the Funds' Boards of Trustees; (vi) expenses of the underlying funds that are paid indirectly as a result of share ownership of the underlying funds; and (vii) expenses that each Fund has incurred but did not actually pay because of an expense offset arrangement, if applicable) exceed the rate, on an annualized basis, set forth on the Exhibits of the average daily net assets allocable to such class. Acquired fund fees and expenses are not fees or expenses incurred by a fund directly but are expenses of the investment companies in which a fund invests. These fees and expenses are incurred indirectly through the valuation of a fund's investment in these investment companies. Acquired fund fees and expenses are required to be disclosed and included in the total annual fund operating expenses in the prospectus fee table. As a result, the net total annual fund operating expenses shown in the prospectus fee table may exceed the expense limits reflected in Exhibits A-D. With regard to the Contractual Limits, the Board of Trustees of the Trust and Invesco Aim may terminate or modify this Memorandum of Agreement prior to the Expiration Date only by mutual written consent. Invesco Aim will not have any right to reimbursement of any amount so waived or reimbursed.

For the Contractual Limits, each of the Trusts and Invesco Aim agree to review the then-current expense limitations for each class of each Fund listed on the Exhibits on a date prior to the Expiration Date to determine whether such limitations should be amended, continued or terminated. The expense limitations will expire upon the Expiration Date unless the Trusts and Invesco Aim have agreed to continue them. The Exhibits will be amended to reflect any such agreement.

For the Voluntary Limits (listed in Exhibits A - D), the Trusts and Invesco Aim agree that these are not contractual in nature and that Invesco Aim may establish, amend and/or terminate such expense limitations at any time in its sole discretion after consultation with the Funds' Boards of Trustees. Any delay or failure by Invesco Aim to update this Memorandum of Agreement with regards to the terminations, extensions, or expirations of the Voluntary Limits shall have no effect on the term of such Voluntary Limitations; the Voluntary Limitations are listed herein for informational purposes only.

It is expressly agreed that the obligations of each Trust hereunder shall not be binding upon any of the Trustees, shareholders, nominees, officers, agents or employees of the Trusts personally, but shall only bind the assets and property of each Fund, as provided in each Trust's Agreement and Declaration of Trust. The execution and delivery of this Memorandum of Agreement have been authorized by the Trustees of the Trusts, and this Memorandum of Agreement has been executed and delivered by an authorized officer of the Trusts acting as such; neither such authorization by such Trustees nor such execution and delivery by such officer shall be deemed to have been made by any of them individually or to impose any liability on any of them personally, but shall bind only the assets and property of the Funds, as provided in each Trust's Agreement and Declaration of Trust.


IN WITNESS WHEREOF, each of the Trusts and Invesco Aim have entered into this Memorandum of Agreement as of the Effective Dates on the attached Exhibits.

MEMORANDUM OF AGREEMENT
(AFFILIATED MONEY MARKET FUND ADVISORY FEE WAIVER)

This Memorandum of Agreement is entered into as of the dates indicated on Exhibit "A" between AIM Counselor Series Trust, AIM Equity Funds, AIM Funds Group, AIM Growth Series, AIM International Mutual Funds, AIM Investment Funds, AIM Investment Securities Funds, AIM Sector Funds, AIM Tax-Exempt Funds, AIM Variable Insurance Funds and Short-Term Investments Trust (each a "Fund" and collectively, the "Funds"), on behalf of the portfolios listed on Exhibit "A" to this Memorandum of Agreement (the "Portfolios"), and Invesco Aim Advisors, Inc. ("Invesco Aim").

For and in consideration of the mutual terms and agreements set forth herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Funds and Invesco Aim agree as follows:

1. Each Fund, for itself and its Portfolios, and Invesco Aim agree that until the expiration date, if any, of the commitment set forth on the attached Exhibit "A" occurs, as such Exhibit "A" is amended from time to time, Invesco Aim will waive advisory fees payable by an Investing Fund in an amount equal to 100% of the net advisory fee Invesco Aim receives on the Uninvested Cash (defined below) from the Affiliated Money Market Fund (defined below) in which the Investing Fund invests (the "Waiver").

i. Invesco Aim's Fund Accounting Group will calculate, and apply, the Waiver monthly, based upon the average investment of Uninvested Cash made by the Investing Fund during the previous month in an Affiliated Money Market Fund.

ii. The Waiver will not apply to those investing Funds that do not charge an advisory fee, either due to the terms of their advisory agreement, or as a result of contractual or voluntary fee waivers.

iii. The Waiver will not apply to cash collateral for securities lending.

For purposes of the paragraph above, the following terms shall have the following meanings:

(a) "Affiliated Money Market Fund" - any existing or future Fund that holds itself out as a money market fund and complies with Rule 2a-7 under the Investment Company Act of 1940, as amended; and

(b) "Uninvested Cash" - cash available and uninvested by a Fund that may result from a variety of sources, including dividends or interest received on portfolio securities, unsettled securities transactions, strategic reserves, matured investments, proceeds from liquidation of investment securities, dividend payments, or new investor capital.

2. Neither a Fund nor Invesco Aim may remove or amend the Waiver to a Fund's detriment prior to requesting and receiving the approval of the Portfolio's Board of Trustee to remove or amend such Waiver. Invesco Aim will not have any right to reimbursement of any amount so waived.


Subject to the foregoing paragraphs, each of the Funds and Invesco Aim agree to review the then-current waivers for each class of the Funds listed on the Exhibit on a date prior to the Expiration Date to determine whether such waivers should be amended, continued or terminated. The waivers will expire upon the Expiration Date unless the Funds and Invesco Aim have agreed to continue them. The Exhibit will be amended to reflect any such agreement.

Nothing in this Memorandum of Agreement is intended to affect any other memorandum of agreement executed by any Fund or Invesco Aim with respect to any other fee waivers, expense reimbursements and/or expense limitations.

IN WITNESS WHEREOF, each Fund, on behalf of itself and its Portfolios listed in Exhibit "A" to this Memorandum of Agreement, and Invesco Aim have entered into this Memorandum of Agreement as of the dates indicated on Exhibit "A".

MEMORANDUM OF AGREEMENT
(12B-1 FEE WAIVERS)

This Memorandum of Agreement is entered into as of the effective date listed on Exhibit "A" of this agreement, between AIM Investment Funds, AIM Investment Securities Funds, AIM Tax-Exempt Funds and Short-Term Investments Trust (each a "Trust" and, collectively, the "Trusts"), on behalf of the funds or portfolios, as applicable, listed on Exhibit "A" to this Memorandum of Agreement (the "Funds"), and Invesco Aim Distributors, Inc. ("Distributors"). Distributors shall and hereby agrees to waive fees of each Fund, on behalf of its respective classes as applicable, severally and not jointly, as indicated in the attached Exhibit "A".

For and in consideration of the mutual terms and agreements set forth herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Trusts and Distributors agree as follows:

For the Contractual Waivers (listed in the attached Exhibit), the Trusts and Distributors agree until at least the date set forth on the attached Exhibit "A" (the "Expiration Date") that Distributors will waive Rule 12b-1 distribution plan fees in an amount equal to the rates as set forth on Exhibit "A" multiplied by the average annual daily net assets allocable to such class. Each Trust's Board of Trustees and Distributors may terminate or modify this Memorandum of Agreement prior to the Expiration Date only by mutual written consent. Distributors will not have any right to reimbursement of any amount so waived.

For the Contractual Waivers, the Trusts and Distributors agree to review the then-current waivers for each class of each Fund listed on Exhibit "A" on a date prior to the Expiration Date to determine whether such waivers should be amended, continued or terminated. The waivers will expire upon the Expiration Date unless the Trusts and AIM have agreed to continue them. Exhibit "A" will be amended to reflect any such agreement.

For any Voluntary Waivers, the Trust and Distributors agree that these are not contractual in nature and that Distributors may establish, amend and/or terminate such expense limitations at any time in its sole discretion after consultation with each Trust's Board of Trustees. Any delay or failure by Distributors to update this Memorandum of Agreement with regards to the terminations, extensions, or expirations of any Voluntary Waivers shall have no effect on the term of such Voluntary Waivers.

It is expressly agreed that the obligations of the Trusts hereunder shall not be binding upon any of the Trustees, shareholders, nominees, officers, agents or employees of the Trusts personally, but shall only bind the assets and property of the Funds, as provided in each Trust's Agreement and Declaration of Trust. The execution and delivery of this Memorandum of Agreement have been authorized by the Trustees of each Trust, and this Memorandum of Agreement has been executed and delivered by an authorized officer of each Trust acting as such; neither such authorization by such Trustees nor such execution and delivery by such officer shall be deemed to have been made by any of them individually or to impose any liability on any of them personally, but shall bind only the assets and property of the Funds, as provided in each Trust's Agreement and Declaration of Trust.


IN WITNESS WHEREOF, the Trusts and Distributors have entered into this Memorandum of Agreement as of the date first above written.

This Master Related Agreement (the "Agreement") is entered into in accordance with Rule 12b-1 under the Investment Company Act of 1940, as amended (the "1940 Act") by each registered investment company, listed in Schedule A to this Agreement (each individually referred to as a "Fund", or collectively, "Funds"), severally, on behalf of each of the series of common stock or beneficial interest, as the case may be, set forth in Schedule A to this Agreement (each, a "Portfolio"), with respect to the Class A Shares of each such Portfolio listed on Schedule A. This Agreement, being made between Invesco Aim Distributors, Inc., formerly A I M Distributors, Inc. ("Distributors") and each Fund, on behalf of each applicable Portfolio, defines the services to be provided by Distributors, or its designees, for which it is to receive payments pursuant to the First Restated Master Distribution Plan (Class A Shares) (the "Plan") adopted by each of the Funds. The Plan has been approved by a majority of the directors/trustees ("Trustees") of each of the Funds, including a majority of the Trustees who have no direct or indirect financial interest in the operation of the Plan or this Agreement (the "Dis-Interested Trustees"), by votes cast in person at a meeting called for the purpose of voting on the Plan.

1. a. Distributors may use payments received pursuant to Paragraph 2 of this Agreement to provide continuing personal shareholder services to customers who may, from time to time, directly or beneficially own shares of the Funds. Continuing personal shareholder services may include but are not limited to, distributing sales literature to customers, answering routine customer inquiries regarding the Funds, assisting customers in changing dividend options, account designations and addresses, and in enrolling in any of several special investment plans offered in connection with the purchase of the Funds' shares, assisting customers in the establishment and maintenance of customer accounts and records and in the placement of purchase and redemption transactions, assisting customers in investing dividends and capital gains distributions automatically in shares, and providing such other services as the Funds or the customer may reasonably request and Distributors agrees to provide. Distributors will not be obligated to provide services which are provided by a transfer agent for a Fund with respect to a Portfolio.

b. Distributors may also use the payments received pursuant to Paragraph 2 of this Agreement for distribution-related services. As used in this Agreement, "distribution-related services" shall mean any activity which is primarily intended to result in the sale of the Shares, including, but not limited to, organizing and conducting sales seminars, implementing advertising programs, engaging finders and paying finders fees, printing prospectuses and statements of additional information (and supplements thereto) and annual and semi-annual reports for other than existing shareholders, preparing and distributing advertising material and sales literature, making supplemental payments to dealers and other institutions as asset-based sales charges, and administering the Plan.

6. Distributors may enter into other similar Master Related Agreements with any other investment company without a Fund's consent.

7. This Agreement shall become effective immediately upon its approval by a majority of the Trustees of each of the Funds, including a majority of the Dis-Interested Trustees, by votes cast in person at a meeting called for the purpose of voting on the Plan and this Agreement.

8. This Agreement shall continue in full force and effect as long as the continuance of the Plan and this Agreement are approved at least annually by a vote of the Trustees, including a majority of the Dis-Interested Trustees, cast in person at a meeting called for the purpose of voting thereon.

This Agreement may be terminated with respect to any Fund at any time without payment of any penalty by the vote of a majority of the Trustees of such Fund who are Dis-interested Trustees or by a vote of a majority of the Fund's outstanding shares, on sixty (60) days' written notice. It will be terminated by any act which terminates the Fund's Plan, and in any event, it shall terminate automatically in the event of its assignment as that term is defined in the 1940 Act.

10. This Agreement may be amended by mutual written agreement of the parties.

Code of Ethics 1


INVESCO
CODE OF ETHICS

(EFFECTIVE FEBRUARY 29, 2008)

I. INTRODUCTION

Invesco(1) has a fiduciary relationship with respect to each portfolio under management. The interests of Clients and of the shareholders of Invesco's investment company Clients take precedence over the personal interests of Invesco and Covered Persons (defined below). Capitalized terms used herein are defined at the end of this document.

This Code of Ethics ("the Code") applies to all:

- Employees of Invesco; and

- Employees of any Invesco affiliate that, in connection with their duties, obtain or are determined by the Compliance Department to have access to, any information concerning recommendations being made by any Invesco entity to any of its Clients.

All individuals covered by the Code are referred to as "Covered Persons."

II.(A) STATEMENT OF FIDUCIARY PRINCIPLES

The following fiduciary principles govern Covered Persons.

- the interests of Clients and shareholders of investment company Clients must be placed first at all times and Covered Persons must not take inappropriate advantage of their positions; and

- all personal securities transactions must be conducted consistent with this Code and in a manner to avoid any abuse of an individual's position of trust and responsibility. This Code is our effort to address conflicts of interest that may arise in the ordinary course of our business.

This Code does not attempt to identify all possible conflicts of interest or to ensure literal compliance with each of its specific provisions. It does not necessarily shield Covered Persons from liability for personal trading or other conduct that violates a fiduciary duty to Clients and shareholders of investment company Clients.

II.(B) COMPLIANCE WITH LAWS, RULES AND REGULATIONS; REPORTING OF VIOLATIONS

All Invesco Employees are required to comply with applicable state and federal securities laws, rules and regulations and this Code. Employees shall promptly report any violations of laws or regulations or any provision of this Code of which they become aware to Invesco's Chief Compliance Officer or


(1) Unless the context indicates otherwise, the term, "Invesco" shall include the following registered investment advisers, each an indirect wholly-owned subsidiary of Invesco Ltd.: Invesco Institutional (N.A.), Inc., Invesco Global Asset Management (N.A.), Inc., Invesco Private Capital, Inc., Invesco Senior Secured Management, Inc. and WL Ross & Company LLC.

Code of Ethics 2


his/her designee. Additional methods of reporting potential violations or compliance issues are described in Section IV of this Code under "Reporting of Potential Compliance Issues."

III. LIMITS ON PERSONAL INVESTING

A. PERSONAL INVESTING

1. Preclearance of Personal Security Transactions. All Covered Persons must pre-clear all personal security transactions involving Covered Securities with the Compliance Department using the automated review system. Covered Securities include all investments that can be made by an Invesco entity for its Clients, including stocks, bonds, municipal bonds, exchange traded funds (ETFs) and any of their derivatives such as options. Covered Securities do not include shares of money market funds, government securities, certificates of deposit or shares of mutual funds not advised by Invesco or AIM. If you are unclear about whether a proposed transaction involves a Covered Security, contact the Compliance Department via email at CodeofEthics(North America)@invesco.com or by phone at 1-877-331-CODE [1-877-331-2633] prior to executing the transaction.

- ANY APPROVAL GRANTED TO A COVERED PERSON TO EXECUTE A PERSONAL SECURITY TRANSACTION IS VALID FOR THAT BUSINESS DAY ONLY, EXCEPT THAT IF APPROVAL IS GRANTED AFTER THE CLOSE OF TRADING DAY SUCH APPROVAL IS GOOD THROUGH THE NEXT TRADING DAY.

The automated review system will review personal trade requests from Covered Persons based on the following considerations:

- BLACK-OUT PERIOD. Invesco does not permit Covered Persons to trade in a Covered Security if a Client has executed a transaction in the same security within the last two trading days or if there is an order on that security currently with the trading desk. For example, if a Client trades on a Monday, Covered Persons may not be cleared until Thursday.

- INVESTMENT PERSONNEL. Investment, Portfolio Administration and IT Personnel may not buy or sell a Covered Security three trading days before or after a Client trades in that security.

- DE MINIMIS EXCEPTIONS. The Compliance Department will apply the following de minimis exceptions in granting preclearance when a Client has recently traded or is trading in a security involved in a Covered Person's proposed personal transaction:

- Equity de minimis exception. If you do not have knowledge of trading activity in a particular equity security, you may execute up to 500 shares of such security in a rolling 30 day period provided the issuer of such security is included in the Russell 1000 Index. The de minimis exception is available to all Covered Persons.

- Fixed income de minimis exception. If you do not have knowledge of trading activity in a particular fixed income security you may execute up to $100,000 of par value of such security. The de minimis exception is available to all Covered Persons.

Code of Ethics 3


The automated review system will confirm that there is no activity currently on the trading desk on the security involved in the proposed personal transaction and check the portfolio accounting system to verify that there have been no Client transactions for the requested security within the last two trading days. For Investments, Portfolio Administration and IT personnel, the Compliance Department will also check the trading activity of affiliates with respect to which such personnel have access to transactional information to verify that there have been no Client transactions in the requested security within the last three trading days. The Compliance Department will notify the Covered Person of the approval or denial of the proposed personal transaction. The approval of a personal securities transaction is only valid for that business day. If a Covered Person does not execute the proposed securities transaction on the date requested, the Covered Person must resubmit the request on another day for approval.

Any failure to preclear transactions is a violation of the Code and will be subject to the following potential sanctions:

- A Letter of Education will be provided to any Covered Person whose failure to preclear is considered immaterial or inadvertent.

- Repeat violations may result in in-person training, probation, withdrawal of personal trading privileges or employment termination, depending on the nature and severity of the violations.

2. Prohibition on Short-Term Trading Profits. Covered Persons are prohibited from engaging in the purchase and sale, or short sale and cover of the same Covered Security within 60 days at a profit. If a Covered Person trades a Covered Security within the 60 day time frame, any profit from the trade will be disgorged to a charity of Invesco's choice.

3. Initial Public Offerings. Covered Persons are prohibited from acquiring any security in an equity Initial Public Offering. Exceptions will only be granted in unusual circumstances and must be approved by the Chief Compliance Officer or General Counsel (or designee) and the Chief Investment Officer of the Covered Person's business unit.

4. Prohibition of Short Sales by Investment Personnel. Investment Personnel are prohibited from effecting short sales of Covered Securities in their personal accounts if an Invesco Client for whose account they have investment management responsibility has a long position in those Securities.

5. Restricted List Securities. Employees requesting pre-clearance to buy or sell a security on the Restricted List may be restricted from executing the trade because of potential conflicts of interest.

6. Brokerage Accounts. Covered Persons may only maintain brokerage accounts with

- discount broker-dealers that provide electronic feeds of confirmations and monthly statements directly to the Compliance Department,

- Invesco-affiliated Broker-dealers, or

- full service broker-dealers.

Code of Ethics 4


As a result, Covered Persons must move any existing brokerage accounts that do not comply with this provision as of the date of this Code to appropriate broker-dealers within six months of the effective date of this Code and every person who becomes a Covered Person under this Code subsequent to the effective date must move all of their brokerage accounts that do not comply with this provision of the Code within thirty (30) days from the date the Covered Person becomes subject to this Code. All Covered Persons must arrange for their broker-dealers to forward to the Compliance Department on a timely basis, duplicate confirmations of all personal securities transactions and copies of periodic statements for all brokerage accounts, preferably in an electronic format.

7. Reporting Requirements.

a. INITIAL HOLDINGS REPORTS. All Covered Persons must provide to the Compliance Department an initial holdings report no later than 10 days after the person becomes a Covered Person (the information must be current within 45 days of the date the person becomes a Covered Person). The initial holdings report shall include the following information:

- The title, number of shares (for equities) and the principal amount (for debt securities) in which the person has direct or indirect Beneficial Ownership;

- The name of any broker-dealer or bank with which the person maintains an account in which any securities are held for the direct or indirect benefit of the person; and

- The date that the report is submitted by the person.

b. QUARTERLY TRANSACTIONS REPORTS. All Covered Persons must report, no later than 30 days after the end of each calendar quarter, the following information for all transactions in a Covered Security in which a Covered Person has a direct or indirect beneficial interest: This includes any Covered Securities held in a 401(k) or other retirement vehicle, including plans sponsored by Invesco or its affiliates.

- The date of all transactions in that quarter, the security name, the number of shares (for equity securities); or the interest rate and maturity date (if applicable) and the principal amount (for debt securities) for each Covered Security;

- The nature of the transaction (buy, sell, etc.);

- The price of the Covered Security at which the transaction was executed;

- The name of the broker-dealer or bank executing the transaction; and

- The date that the report is submitted to the Compliance Department.

ALL COVERED PERSONS MUST SUBMIT A QUARTERLY REPORT REGARDLESS OF WHETHER THEY HAVE EXECUTED TRANSACTIONS DURING THE QUARTER OR NOT. If a Covered Person did not execute transactions subject to reporting requirements during a quarter, the report must include a representation to that effect. Covered Persons need not include transactions made through

Code of Ethics 5


an Automatic Investment Plan, Dividend Reinvestment Plan or
similar plans in the quarterly transaction report.

Additionally, Covered Persons must report information on any new
brokerage account established by the Covered Person during the

retirement vehicle, including plans sponsored by Invesco or its

affiliates) including:

- The date the account was established;

- The name of the broker-dealer or bank; and

- The date that the report is submitted to the Compliance Department.

The Compliance Department may identify transactions by Covered Persons that technically comply with the Code for review based on any pattern of activity that has an appearance of a conflict of interest.

- The security and the number of shares (for equities) or the interest rate and maturity date (if applicable) and principal amount (for debt securities) for each Covered Security in which the Covered Person has any direct or indirect Beneficial Ownership;

- The name of the broker-dealer or bank with or through which the transaction was effected; and

- The date that the report is submitted by the Covered Person to the Compliance Department.

d. Managed Accounts. Covered Persons must make an annual report with respect to transactions held in an account over which the Covered Person has granted exclusive discretion to a professional money manager or other third party. Covered Persons must receive approval from the Compliance Department to establish and maintain such an account and must provide written evidence that exclusive discretion over the account has been turned over to a professional money manager or other third party. Covered Persons are not required to pre-clear or list transactions for such managed accounts in the automated review system; however, Covered Persons with these types of accounts must provide an annual certification that they do not exercise direct or indirect Control over the managed accounts.

e. Annual Certification. All Covered Persons must certify annually that they have read and understand the Code and recognize that they are subject to the Code. In addition, all Covered Persons must certify annually that they have complied with the requirements of the Code and that they have disclosed or reported all personal securities transactions

Code of Ethics 6


required to be disclosed or reported under the Code. The Invesco
Risk Management Committee will review and approve the Code
annually.

8. Private Securities Transactions. Covered Persons may not
engage in a Private Securities Transaction without first giving
the Compliance Department a detailed written notification
describing the transaction and indicating whether or not they
will receive compensation and obtaining prior written permission
from the Compliance Department. Investment Personnel who have
been approved to acquire securities of an issuer in a Private
Securities Transaction must disclose that investment to the
Compliance Department and the Chief Investment Officer of the
Investment Personnel's Invesco business unit when they are
involved in a Client's subsequent consideration of an investment
in the same issuer. The business unit's decision to purchase such
securities on behalf of Client account must be independently
reviewed by Investment Personnel with no personal interest in
that issuer.

9. Excessive Short Term Trading in Funds. Employees are
prohibited from excessive short term trading of any mutual fund
advised or sub-advised by Invesco or AIM and are subject to
various limitations on the number of transactions as indicated in
the respective prospectus and other fund disclosure documents.

B. INVESCO LTD. SECURITIES

1. No Employee may effect short sales of Invesco Ltd. securities.

2. For all Covered Persons, transactions, including transfers by gift, in Invesco Ltd. securities are subject to pre- clearance regardless of the size of the transaction, and are subject to "black-out" periods established by Invesco Ltd. and holding periods prescribed under the terms of the agreement or program under which the securities were received.

3. Holdings of Invesco Ltd. securities in Covered Persons accounts are subject to the reporting requirements specified in Section
II.5 of this Code.

C. LIMITATIONS ON OTHER PERSONAL ACTIVITIES

1. Outside Business Activities. Absent prior written approval of the Compliance Department, Employees may not serve as directors, officers or employees of unaffiliated public or private companies, whether for profit or non-profit. If the outside business activity is approved, the Employee must recuse himself or herself from making Client investment decisions concerning the particular company or issuer as appropriate, provided that this recusal requirement shall not apply with respect to certain Invesco Employees who may serve on corporate boards as a result of, or in connection with, Client investments made in those companies. All employees must always comply with all applicable Invesco policies and procedures, including those prohibiting the use of material non-public information in Client or employee personal trades.

2. Gift and Entertainment Policy. Invesco Employees may not give or accept Gifts or Entertainment that may be considered excessive either in dollar value or frequency to avoid the appearance of any potential conflict of interest. Under no circumstances may an Employee give or accept cash or any possible cash equivalent from a broker or vendor. Employees must report

Code of Ethics 7


receipt or giving of ALL Gifts and Entertainment within thirty (30) calendar days by submitting a Gift Report within the automated review system.

An Employee may not provide or receive any Gift or Entertainment that is conditioned upon Invesco, its parents or affiliates doing business with the entity or person involved.

- ENTERTAINMENT. Invesco Employees must report Entertainment with the Compliance Department within thirty (30) calendar days after the receipt or giving by submitting a Gift Report within the automated review system. The requirement to report Entertainment includes dinners or any other event with an Invesco Business Partner in attendance.

Examples of Entertainment that may be excessive in value include Super Bowl tickets, tickets to All-Star games, hunting trips, or ski trips. An occasional ticket to a sporting event, golf outing or concert when accompanied by the Business Partner may not be excessive.

Additionally, Invesco Employees may not reimburse Business Partners for the cost of tickets that would be considered excessive or for travel related expenses without approval of the Compliance Department.

- GIFTS. All Gifts given or received must be reported to the Compliance Department within thirty (30) calendar days after the receipt or giving by submitting a Gift Report within the automated review system. Invesco Employees are prohibited from accepting or giving the following:

- single Gifts valued in excess of $100 in any calendar year; or

- Gifts from one person or firm valued in excess of $100 during a calendar year period.

3. US Department of Labor Reporting: Under current US Department of Labor (DOL) regulations, Invesco is required to disclose to the Department certain specified financial dealings with a union or officer, agent, shop steward, employee, or other representative of a union (collectively referred to as "union officials"). Under the Regulations, practically any gift or entertainment furnished by Invesco employees to a union or union official is considered a payment reportable to the DOL.

Although the Regulations provide for a de minimis exemption from the reporting requirements payments made to a union or union official which do not exceed $250 a year, that threshold applies to all of Invesco's employees in the aggregate with respect to each union or union official. Therefore, it is Invesco policy to require that ALL gifts or entertainment furnished by every employee be reported to Invesco using the Invesco Finance Department's expense tracking application, Oracle E-Business Suite or any other application deployed for that purpose which has the capability to capture all the required details of the payment. Such details include the name of the recipient, union affiliation, address, amount of payment, date of payment, purpose and circumstance of payment, including the terms of any oral agreement or understanding pursuant to which the payment was made.

Code of Ethics 8


Invesco is obligated to reports all payments, subject to the de minimis exemption, to the DOL on Form LM-10 Employer Report.

If you have any question whether a payment to a union or union official is reportable, please contact the Compliance Department. A failure to report a payment required to be disclosed will be considered a material violation of this Code. The DOL also requires all unions and union officials to report payments they receive from entities such as Invesco and their employees.

D. PARALLEL INVESTING PERMITTED

Subject to the provisions of this Code, Employees may invest in or own the same securities as those acquired by Invesco for its Clients.

IV. REPORTING OF POTENTIAL COMPLIANCE ISSUES

Invesco has created several channels for Employees to raise compliance issues and concerns on a confidential basis. An Employee should first discuss a compliance issue with their supervisor, department head or with Invesco's General Counsel or Chief Compliance Officer. Human Resources matters should be directed to the Human Resources Department, an additional anonymous vehicle for reporting such concerns.

In the event that an Employee does not feel comfortable discussing compliance issues through normal channels, the Employee may anonymously report suspected violations of law or Invesco policy, including this Code, by calling the toll-free Invesco Compliance Reporting Line, 1-866-297-3627 which is available to employees of multiple operating units of Invesco Ltd. When you dial this number and you are asked for your name, use "Invesco." To ensure your confidentiality, this phone line is provided by an independent company. It is available 24 hours a day, 7 days a week. All calls to the Compliance Reporting Line will be reviewed and handled in a prompt, fair and discreet manner. Employees are encouraged to report these questionable practices so that Invesco has an opportunity to address and resolve these issues before they become more significant regulatory or legal issues.

V. ADMINISTRATION OF THE CODE OF ETHICS

Invesco has used reasonable diligence to institute procedures reasonably necessary to prevent violations of this Code.

No less frequently than annually, Invesco will furnish to the Invesco Risk Management Committee (RMC), or such committee as it may designate, a written report that:

- describes significant issues arising under the Code since the last report to the RMC, including information about material violations of the Code and sanctions imposed in response to material violations; and

- certifies that the Invesco has adopted procedures reasonably designed to prevent Covered Persons from violating the Code.

Code of Ethics 9


VI. SANCTIONS

Upon discovering a material violation of the Code, the Compliance Department will notify Invesco's Chief Compliance Officer (CCO). The CCO will notify the RMC of any material violations at the next regularly scheduled meeting.

The Compliance Department will issue a letter of education to the Covered Persons involved in violations of the Code that are determined to be inadvertent or immaterial.

Invesco may impose additional sanctions in the event of repeated violations or violations that are determined to be material or not inadvertent, including disgorgement of profits, a letter of censure or suspension, or termination of employment.

INVESCO LTD.

CODE OF CONDUCT

INTRODUCTION

Our company's Core Purpose and Mission are a logical beginning point for our Code of Conduct:

Invesco is committed to "Helping People Worldwide Build Their Financial Security". That Core Purpose underlies our Mission, which is to deliver superior investment performance worldwide. Over the years, Invesco has developed a set of values that will continue to help us achieve our Core Purpose and Mission. Our values include:

- Working with integrity

- Respecting our employees and clients

- Empowering people

This Code of Conduct ("Code of Conduct" or "Code") has been created to assist us in accomplishing our Core Purpose and Mission. It contains a number of policies and standards which, when taken together, are designed to help define the essence of the conduct of an Invesco representative. These policies and standards are also intended to provide guidance to Invesco personnel in fulfilling their obligations to comply with applicable laws, rules and regulations. This Code of Conduct applies to all officers and other employees of Invesco and its subsidiaries (collectively, "Covered Persons"). These standards are neither exclusive nor complete. Additional company policies and rules can be found in the company's Intranet site, and others may be published to company personnel from time to time. Covered Persons are required to comply with all applicable laws, rules and regulations, whether or not specifically addressed in these policies. For additional guidance, or if you have questions regarding the existence, interpretation or application of any law, rule or regulation, please contact your supervisor, the General Counsel of your business unit or division, or the Invesco General Counsel.

Page 1 of 23

Our culture is based upon a set of shared values and principles. These include working with integrity and commitment to our clients, colleagues and communities. In practice, this means that our clients' interests must always come first, that Covered Persons should treat each other with respect and consideration, and that Invesco should participate as a responsible corporate citizen in every community in which it operates. This commitment is a vital part of our achieving our principal responsibility as a publicly-held company:
producing a fair return on our shareholders' capital.

This Code of Conduct contains broad and general principles that supplement the specific policies, procedures and training within each business unit of Invesco.

YOUR RESPONSIBLITIES

One person's misconduct can damage our entire company's hard-earned reputation and compromise the public's trust in the company. Every Covered Person should therefore become familiar with this Code and abide strictly by its provisions. In brief:

- It is your responsibility at all times to comply with the law and behave in an ethical manner.

- This Code cannot anticipate every possible situation or cover every topic in detail. The company has established special policies to address specific subjects and will update this Code and those specific policies from time-to-time. If you are unclear about a situation, stop and ask for guidance before taking action.

- Failure to obey laws and regulations violates this Code and may expose both you and the company to criminal or civil sanctions. Any violation of this Code or other company policies may result in disciplinary action, up to and including termination of employment. The company may also seek civil remedies from you and even refer criminal misconduct to law enforcement agencies.

- You are responsible for reporting possible violations of this Code to the company (see below).

- If you have a question about a topic covered in this Code or a concern regarding any conduct, please speak with your supervisor or with an appropriate member of the Legal & Compliance Department.

- If you are aware of a violation and are uncomfortable speaking with any of these people or wish to remain anonymous, you may call the toll-free Invesco Compliance Reporting Line (the "Compliance Reporting Line"). If you are calling from a U.S. or Canadian location dial 1-866-297-3627. For calls from all other locations, dial an international operator and request a collect call to 1-704-943-1136. When asked for your name use "Invesco." (See further details below.)

Page 2 of 23

- If you are an attorney or an executive officer of the company, you may have additional reporting or other obligations under specific rules applicable to you, such as the POLICY FOR REPORTING BY ATTORNEYS EMPLOYED BY INVESCO LTD. AND ITS SUBSIDIARIES, and you should also comply with such rules.

STATEMENT OF GENERAL PRINCIPLES

Invesco with its subsidiaries and various divisions operates in a highly-regulated and complex environment. There are numerous layers of overlapping, and occasionally conflicting, laws, customs and local practices. This Code of Conduct was designed to provide all of us who are part of the Invesco group with a clear statement of our firm's ethical and cultural standards.

We operate in major countries and securities markets throughout the world. Generally, we serve our clients as fiduciaries.

Fiduciary businesses are generally held to a higher standard of conduct than other businesses, and as such there are special obligations that apply. The following key duties and principles govern our conduct as fiduciaries:

- Best interests of clients - As fiduciaries, we have a duty to act with reasonable care, skill and caution in the best interests of our clients, and to avoid conflicts of interest.

- Global fiduciary standards - Invesco seeks to maintain the same high fiduciary standards throughout the world, even though those standards may not be legally required, or even recognized, in some countries.

- Compliance with applicable laws, rules and regulations - We have a duty to comply with the laws, rules and regulations of the jurisdictions in which we operate, and to comply with the terms of our agreements with our clients.

- Client confidentiality - We must maintain the confidentiality of information relating to the client, and comply with the data protection requirements imposed by many jurisdictions.

- Information - Clients must be provided with timely and accurate information regarding their accounts.

- Segregation and protection of assets - Processes must be established for the proper maintenance, control and protection of client assets. Fiduciary assets must be segregated from Invesco assets and property.

Page 3 of 23

- Delegation of duties - Fiduciary duties should be delegated only when the client consents and where permitted by applicable law. Reasonable care, skill and caution must be exercised in the selection of agents and review of their performance.

- Client guidelines - Invesco is responsible for making investment decisions on behalf of clients that are consistent with the prospectus, contract, or other controlling document relating to the client's account.

- Relations with regulators - We seek relationships with regulators that are open and responsive in nature.

1. Compliance with Laws, Rules and Regulations

Invesco strives to ensure that all activity by or on behalf of Invesco is in compliance with applicable laws, rules and regulations ("applicable laws"). Many of these applicable laws are specifically described in this Code of Conduct and in other Invesco and business unit policies and procedures. In the conduct of our business, all Covered Persons are required to comply with all applicable laws.

2. Fair and Honest Dealing

Covered Persons shall deal fairly and honestly with Invesco's shareholders, customers, suppliers, competitors and employees. Covered Persons shall behave in an ethical manner and shall not take unfair advantage of anyone through manipulation, concealment, abuse of privileged information, misrepresentation of material facts, or any other unfair dealing practice.

3. Conflicts of Interest

Invesco and its Covered Persons must adhere to the highest standards of honest and ethical conduct. These include, but are not limited to, sensitivity to the existence of a conflict of interest or the appearance of a conflict of interest. Conflicts of interest can arise in many ways, and we must all be sensitive to those situations in which they are most likely to be present. A conflict of interest exists when a Covered Person's personal interest interferes, or appears to interfere, in any way with the interests of Invesco or its clients, or when a Covered Person otherwise takes actions or has interests that may make it difficult to perform his or her company work objectively and effectively. For example, a conflict of interest would arise if a Covered Person, or a member of his or her family, receives improper personal benefits as a result of his or her position with Invesco.

All Covered Persons owe a duty of undivided and unqualified loyalty to Invesco and may not use their positions improperly to profit personally or to assist others in profiting at the expense of the company. All Covered Persons are therefore expected and

Page 4 of 23

required to regulate their activities so as to avoid conflicts of interest. In addition, Covered Persons shall promptly communicate to the applicable member of the Legal & Compliance Department any material transaction or relationship that reasonably could be expected to give rise to a conflict of interest so that the company and the Covered Person may take steps to minimize the conflict.

Covered Persons shall not take for personal use (or for use by a family member) any business opportunity learned of during the course of serving Invesco, using Invesco property or as a result of such individual's position with Invesco. To the extent that an employee or officer learns of a business opportunity that is within Invesco's existing or proposed lines of business, the employee or officer should inform his or her supervisor, the divisional or business unit General Counsel, or the Board of Directors, as appropriate, of the business opportunity and refrain from personally pursuing the matter until such time as Invesco decides to forego the business opportunity. At no time may any employee or officer utilize any Invesco property, information or position to generate personal gain or engage or participate in any business that directly competes with Invesco.

While not all-inclusive, the following examples of outside financial interests will serve to illustrate some of the types of activities that might cause conflicts of interest:

- Ownership or other interest in or employment by any outside concern which does business with Invesco. This does not apply to stock or other investments in a publicly-held company, provided that the stock and other investments do not, in the aggregate, exceed 5% of the outstanding ownership interests of such company. Invesco may, following a review of the relevant facts, permit ownership interests which exceed these amounts if management or the Board of Directors, as appropriate, concludes that such ownership interests will not adversely affect Invesco's business interests or the judgment of the affected Covered Person.

- Conducting business, not on behalf of Invesco, with any Invesco vendor, supplier, contractor, agency, or any of their directors, officers or employees.

- Representation of Invesco by a Covered Person in any transaction in which he or she, or a family member, has a substantial personal interest.

- Disclosure or use of confidential, special or inside information of or about Invesco, particularly for personal profit or advantage of the Covered Person or a family member of such person.

- Competition with Invesco by a Covered Person, directly or indirectly, in the purchase, sale or ownership of property or services or business investment opportunities.

Page 5 of 23

As described in more detail in Sections 4, 5 and 6 below, acting as an officer or director of an outside organization, personal share dealing, and the use of material non-public information represent additional areas where conflicts can arise and are of particular sensitivity.

In addition to conflicts of interest between the company and its Covered Persons, conflicts of interest may arise between the company and its clients, including investment funds. Where a Covered Person is trading in securities owned by client accounts, or where a portfolio management team for a hedge fund also manages mutual funds that invest in the same securities, are each examples of situations that may give rise to real or apparent conflicts of interest. All Covered Persons must follow the procedures in place within their respective divisions and business units and must also be sensitive to the types of situations that can give rise to such conflicts or apparent conflicts.

4. Outside Activities and Compensation

No Covered Person shall perform work or render services for any competitor of Invesco or for any organization with which Invesco does business or which seeks to do business with Invesco, outside of the normal course of his or her employment with Invesco, without the prior written approval of the company. Nor shall any such person be a director, officer, or consultant of such an organization, or permit his or her name to be used in any fashion that would tend to indicate a business connection with such organization, without such approval. Outside organizations can include public or private corporations, partnerships, charitable foundations and other not-for-profit institutions. With the above approval, Covered Persons may receive compensation for such activities.

Service with organizations outside of Invesco can, however, raise serious regulatory issues, including conflicts of interest and access to material non-public information.

As an outside board member or officer, a Covered Person may come into possession of material non-public information about the outside company or other public companies. It is critical that a proper information barrier be in place between Invesco and the outside organization, and that the Covered Person does not communicate such information to other Covered Persons in violation of the information barrier.

Similarly, Invesco may have a business relationship with the outside organization or may seek a relationship in the future. In those circumstances, the Covered Person must not be involved in any way in the business relationship between Invesco and the outside organization.

Invesco retains the right to prohibit membership by Covered Persons on any board of directors/trustees or as an officer of an outside organization where such membership might conflict with the best interests of the company. Approval will be granted on a

Page 6 of 23

case-by-case basis, subject to proper resolution of potential conflicts of interest. Outside activities will be approved only if these issues can be satisfactorily resolved.

5. Personal Share Dealing

Purchasing and selling securities in a Covered Person's own account, or accounts over which the Covered Person has access or control, can give rise to potential conflicts of interest. As fiduciaries, we are held to the highest standards of conduct. Improperly gaining advance knowledge of portfolio transactions, or conducting securities transactions based upon information obtained at Invesco, can be a violation of those standards.

All personal securities transactions must be pre-cleared unless an exemption is obtained. Generally, an exemption will be granted only for Covered Persons whose duties do not give them access to information regarding the sale or purchase of, or the recommendation to sell or purchase, securities in any portfolio. Transactions in certain retirement benefit plans, such as 401(k)s and Money Purchase Plans, and in specified categories of securities, are exempt from pre-clearance. Every Covered Person must also comply with the specific rules in effect in this area for the Covered Person's division or business unit.

Invesco also has policies that specifically cover personal transactions in the shares and American Depositary Shares of the company. All Covered Persons are obligated to follow those procedures whenever they conduct such transactions.

6. Information Barriers and Material Non-Public Information

In the conduct of our business, Covered Persons may come into possession of material non-public information. This information could concern an issuer, a client, a portfolio, the market for a particular security, or Invesco itself. The purchase or sale of Invesco's securities or the securities of other publicly-traded companies while aware of material nonpublic information about such company, or the disclosure of material nonpublic information to others who then trade in such company's securities, is prohibited by this Code of Conduct and by United States and other jurisdictions' securities laws. Invesco and its subsidiaries have adopted insider trading policies that apply to all Covered Persons. All Covered Persons should review the insider trading policies carefully and follow the policies and procedures described therein. The failure of a Covered Person to comply with the company's insider trading policy may subject him or her to company-imposed sanctions, up to and including termination for cause, whether or not the failure to comply results in a violation of law. You should seek the advice of the applicable divisional or business unit General Counsel on any questions regarding this subject and the company's insider trading policy. All Covered Persons are prohibited from using such information in ways that violate the law, including for personal gain. Non-public information must be kept confidential, which may include keeping it confidential from other Covered Persons.

7. Anti-Bribery and Dealings with Governmental Officials

Special care must be taken when dealing with government customers. Activities that might be appropriate when working with private sector customers may be improper and even illegal when dealing with government employees, or when providing goods and services to another customer who, in turn, will deliver the company's product to a government end user. Many of the countries in which Invesco conducts its business prohibit the improper influencing of governmental officials or other persons by the payment of bribes, gifts, political contributions, lavish hospitality or by other means. Our policy requires adherence to those restrictions.

Do not directly or indirectly promise, offer or make payment in money or anything of value to anyone, including a government official, agent or employee of a government, political party, labor organization or business entity or a candidate of a political party, or their families, with the intent to induce favorable business treatment or to improperly affect business or government decisions. This policy prohibits actions intended either to influence a specific decision or merely to enhance future relationships. In general, all travel and entertainment that Covered Persons provide to governmental officials must be pre-approved within the appropriate business unit. If approved, a written confirmation that such expenses do not violate local law must be obtained from an appropriate third party (e.g., the business unit's legal counsel or the government official's supervisor).

Covered Persons shall comply with all laws, rules and regulations governing political campaign finance and lobbying activities and shall not engage in any conduct that is intended to avoid the application of such laws to activities undertaken on Invesco's behalf. In addition, appropriate executive officers shall monitor compliance with lobbyist registration and disclosure requirements by all individuals who act on behalf of Invesco.

These prohibitions extend to any consultants or agents we may retain on behalf of Invesco.

8. Anti-Discrimination and Harassment

Invesco is committed to providing a work environment that is free of discrimination and harassment. Such conduct, whether overt or subtle, is demeaning, may be illegal, and undermines the integrity of the employment relationship.

Sexual harassment can include unwelcome sexual advances, requests for sexual favors, pressure to engage in a sexual relationship as a condition of employment or promotion, or conduct which creates a hostile or offensive work environment.

Discrimination can take many forms including actions, words, jokes, or comments based upon an individual's race, citizenship, ethnicity, color, religion, sex, veteran status,

Page 8 of 23

national origin, age, disability, sexual orientation, marital status or other legally protected characteristic. Any Covered Person who engages in harassment or discrimination will be subject to disciplinary action, up to and including termination of employment.

9. Anti-Money Laundering

In the global marketplace, the attempted use of financial institutions and instruments to launder money is a significant problem that has resulted in the passage of strict laws in many countries. Money laundering is the attempt to disguise money derived from or intended to finance illegal activity including drug trafficking, terrorism, organized crime, fraud, and many other crimes. Money launderers go to great lengths to hide the sources of their funds. Among the most common stratagems are placing cash in legitimate financial institutions, layering between numerous financial institutions, and integrating the laundered proceeds back into the economy as apparently legitimate funds.

All Covered Persons must be vigilant in the fight against money laundering, and must not allow Invesco to be used for money laundering. Each business unit has developed an anti-money laundering program that is consistent with Invesco's group-wide policy. Each Covered Person must comply with the applicable program.

10. Antitrust

The laws of many countries are designed to protect consumers from illegal competitive actions such as price fixing and dividing markets. It is Invesco's policy and practice to compete based on the merits of our products and services. In order to further that policy, Covered Persons must not fix or control prices with competitors, divide up territories or markets, limit the production or sale of products, boycott certain suppliers or customers, unfairly control or restrict trade in any way, restrict a competitor's marketing practices, or disparage a competitor. Covered Persons must never discuss products, pricing or markets with competitors with the intent to fix prices or divide markets.

11. Data Privacy

Data privacy, as it relates both to our clients and our employees, has become a major political and legal issue in many jurisdictions in which we do business. A variety of laws in each of those jurisdictions governs the collection, storage, dissemination, transfer, use, access to and confidentiality of personal information and patient health information. These laws can work to limit transfers of such data across borders and even among affiliated entities in the Invesco group of companies. Invesco and its Covered Persons will comply with all provisions of these laws that relate to its business, including the privacy, security and electronic transmission of financial, health and other personal information. The company expects its Covered Persons to keep all such data

Page 9 of 23

confidential and to protect, use and disclose information in the conduct of our business only in compliance with these laws. The company will consider and may release personal information to third parties to comply with law or to protect the rights, property or safety of Invesco and its customers. . In accordance with Invesco policies, each business unit has developed required disclosures and data security procedures applicable to that business unit. All Covered Persons must comply with the applicable procedures.

With respect to Invesco Covered Persons, all salary, benefit, medical and other personal information relating to Covered Persons shall generally be treated as confidential. Personnel files, payroll information, disciplinary matters, and similar information are to be maintained in a manner designed to protect confidentiality in accordance with applicable laws. All Covered Persons shall exercise due care to prevent the release or sharing of such information beyond those persons who may need such information to fulfill their job functions. Notwithstanding the foregoing, all personnel information belongs solely to Invesco and may be reviewed or used by the company as needed to conduct its business.

12. Communications with the Media and Analysts

Invesco has a long-standing policy of co-operating with the news media and the financial community. This policy is intended to enhance respect for the company, provide accurate information, and achieve our business goals.

Invesco employs media relations professionals who are responsible for handling all contacts with the news media. Invesco's Communications and Corporate Affairs Department is responsible for formulating and directing our media relations policy worldwide. Other Invesco employees may not speak to or disseminate information to the news media unless such contact has been requested and arranged by or coordinated with an Invesco media relations professional in accordance with the company's media relations policy. Any contact from the news media should be referred promptly and without comment to an Invesco media relations professional. If you do not know the appropriate media relations professional for your unit, you can refer the contact to the Invesco Communications and Corporate Affairs Department.

Many countries have detailed rules with regard to the dissemination of information about public companies. In particular, a public company must have procedures for controlling the release of information that may have a material impact on its share price. The Chief Executive Officer and the Chief Financial Officer are responsible for Invesco's relationships with the financial community, including the release of price sensitive information. Other Invesco employees may not speak to or disseminate information regarding the company to the financial community (including analysts, investors, shareholders, Company lenders, and rating agencies) unless such contact has been requested and arranged by the Chief Executive Officer, the Chief Financial Officer or the Investor Relations Group within the Finance Department.

13. Electronic Communications

The use of electronic mail, the Internet and other technology assets is an important part of our work at Invesco. Used improperly, this technology presents legal and business risks for the company and for individual employees. There are also important privacy issues associated with the use of technology, and related regulations are evolving.

In accordance with Invesco's Electronic Communications policies, all Covered Persons are required to use information technology for proper business purposes and in a manner that does not compromise the confidentiality of sensitive or proprietary information. All communications with the public, clients, prospects and fellow employees must be conducted with dignity, integrity, and competence and in an ethical and professional manner.

We must not use information technology to: transmit or store materials which are obscene, pornographic, or otherwise offensive; engage in criminal activity; obtain unauthorized access to data or files; commit copyright violations; install personal software without permission; or make Internet statements, without permission, that suggest that the user is speaking on behalf of Invesco or its affiliates.

14. Gifts and Relationships with Customers and Suppliers

Invesco seeks to do business with clients and suppliers on a fair and equitable basis. We may not accept gifts of other than nominal value, or lavish entertainment, or other valuable benefits or special favors from customers or suppliers. We must observe any limits imposed by our business unit's policies, local laws, or regulations with respect to the acceptance of gifts or gratuities.

15. International Issues

If you conduct business for Invesco outside of the U.S., in addition to being familiar with the local laws of the other countries involved, be sure you are familiar with the following U.S. laws and regulations. Violations of these laws can result in substantial fines, imprisonment and severe restrictions on the company's ability to do business.

FOREIGN CORRUPT PRACTICES ACT

The United States Foreign Corrupt Practices Act (FCPA) and similar laws in many other countries have a variety of provisions that regulate business in other countries and with foreign citizens. In essence, these laws make it a crime to promise or give anything of value to a foreign official or political party in order to obtain or keep business or obtain any improper advantage. It is also illegal to make payments to agents, sales representatives or other third parties if you have reason to believe your gift will be used illegally. Seek advice from the appropriate member of the Legal & Compliance

Page 11 of 23

Department for interpretation of the FCPA or similar laws if you are involved in any business dealings that involve foreign countries.

ANTI-BOYCOTT LAWS

From time to time, various countries may impose restrictions upon the ability of businesses in their jurisdiction to engage in commerce with designated individuals, countries or companies. These laws are commonly referred to as boycotts or trade embargoes. It may be against the law to cooperate in any boycotts between foreign countries not sanctioned by the laws of the place where your office is located. All requests for boycott support or boycott-related information must be reported to your supervisor and the member of the Legal & Compliance Department with responsibility for your office.

Similarly, many countries contribute the names of criminal or terrorist organizations or individuals to a common database and require financial institutions to screen customer lists against the database as part of their "Know Your Customer" obligations. We must be aware of, and where appropriate, adhere to any such restrictions.

EMBARGO SANCTIONS

The United States Treasury Department's Office of Foreign Assets Control prohibits U.S. companies and their foreign subsidiaries from doing business with certain countries and agencies and certain individuals. The laws of other countries may have similar types of prohibitions. The regulations vary depending on the country and the type of transaction and often change as countries' foreign policies change. If you are aware of any sensitive political issues with a country in which Invesco is doing or considering doing business, seek advice from the appropriate member of the Legal & Compliance Department.

16. Political Activities and Lobbying

Covered Persons are encouraged to vote in elections for which they are eligible, and to make contributions supporting candidates or parties of their choice. Covered Persons are also encouraged to express their views on government, legislation and other matters of local or national interest.

Many jurisdictions have imposed severe and complex restrictions on the ability of individuals and companies to make political contributions. You should assume that Invesco and its Covered Persons are generally prohibited from certain types of political activities, and you must be familiar with the rules in effect for your business unit. No Covered Person may, under any circumstances, use company funds to make political contributions without the prior written approval of a member of the Legal & Compliance Department, nor may you represent your personal political views as being those of the company.

Page 12 of 23

17. Retention of Books and Records

Invesco corporate records are important assets. Corporate records include essentially everything you produce as a Covered Person, regardless of its format. A corporate record may be in the form of paper, computer tapes, microfilm, e-mail, or voice mail. It may be something as obvious as a memorandum or a contract or something not as obvious, such as a desk calendar, an appointment book, or an expense record.

Invesco is required by law to maintain certain types of corporate records, usually for a specified period of time. Failure to retain such documents for such minimum periods could subject Invesco to penalties and fines, cause the loss of rights, obstruct justice, place Invesco in contempt of court, or place Invesco at a serious disadvantage in litigation. However, storage of voluminous records over time is costly. Therefore, Invesco has established controls to assure retention for required periods and timely destruction of retrievable records, such as paper copies and records on computers, electronic systems, microfiche, and microfilm. Even if a document is retained for the legally required period, liability could still result if a document is destroyed before its scheduled destruction date.

Invesco and its affiliates are subject to the regulatory requirements of numerous countries and regulatory agencies. Virtually all of them have specific requirements concerning the creation, maintenance and storage of business records. Invesco expects all Covered Persons to become familiar with and fully comply with the records retention/destruction schedule for the departments and office locations for which they work. If you believe documents should be retained beyond the applicable retention period, consult with the Legal & Compliance Department.

18. Sales and Marketing Materials

Invesco is committed to building sustained, open, and honest relationships with our customers, and to complying with all relevant regulatory requirements. This requires that all marketing and sales-related materials be prepared under standards approved by the Legal & Compliance Department and, prior to use, reviewed and approved by the appropriate supervisor within a business unit. Covered materials include requests for proposals, client presentations, performance summaries, advertisements, and published market commentaries.

19. Substance Abuse

Invesco is committed to providing a safe and healthy work place for all employees. The use, possession, sale, transfer, purchase, or being "under the influence" of drugs at any time while on company premises or on company business is prohibited. The term "drug" includes alcoholic beverages (other than in connection with entertainment

Page 13 of 23

events, or in other appropriate settings), prescriptions not authorized by your doctor, inhalants, marijuana, cocaine, heroin and other illegal substances.

20. Confidential Information

Confidential information includes all non-public information that might be of use to competitors, or harmful to the company or its customers, if disclosed. All information (in any form, including electronic information) that is created or used in support of company business activities is the property of Invesco. This company information is a valuable asset and Covered Persons are expected to protect it from unauthorized disclosure. This includes Invesco customer, supplier, business partner and employee data. United Kingdom, United States (federal and state) and other jurisdictions' laws may restrict the use of such information and impose penalties for impermissible use or disclosure.

Covered Persons must maintain the confidentiality of information entrusted to them by the company or its customers, vendors or consultants except when disclosure is properly authorized by the company or legally mandated. Covered Persons shall take all reasonable efforts to safeguard such confidential information that is in their possession against inadvertent disclosure and shall comply with any non-disclosure obligations imposed on Invesco in its agreements with third parties.

Information pertaining to Invesco's competitive position or business strategies, and information relating to negotiations with Covered Persons or third parties, should be protected and shared only with Covered Persons having a need to know such information in order to perform their job responsibilities.

21. Protection and Proper Use of Company Assets

All Covered Persons shall strive to preserve and protect the company's assets and resources and to promote their efficient use. The standards set forth below are intended to guide Covered Persons by articulating Invesco's expectations as they relate to activities or behaviors that may affect the company's assets.

Personal Use of Corporate Assets

Theft, carelessness and waste have a direct impact on Invesco's profitability. Covered Persons are not to convert assets of the company to personal use. Company property should be used for the company's legitimate business purposes and the business of the company shall be conducted in a manner designed to further Invesco's interest rather than the personal interest of an individual Covered Person. Covered Persons are prohibited from the unauthorized use or taking of Invesco's equipment, supplies, materials or services. Prior to engaging in any activity on company time which will result in remuneration to the Covered Person or the use of Invesco's equipment, supplies, materials or services for personal or non-work related purposes, officers and

Page 14 of 23

other Covered Persons shall obtain the approval of the supervisor of the appropriate business unit.

Use of Company Software

Covered Persons use software programs for word processing, spreadsheets, data management, and many other applications. Software products purchased by the company are covered by some form of licensing agreement that describes the terms, conditions and allowed uses. It is the company's policy to respect copyright laws and observe the terms and conditions of any license agreements. Copyright laws in the United States and other countries impose civil and criminal penalties for illegal reproductions and use of licensed software. You must be aware of the restrictions on the use of software and abide by those restrictions. Invesco business equipment may not be used to reproduce commercial software. In addition, you may not use personal software on company equipment without prior written approval.

Computer Resources/E-mail

The company's computer resources, which include the electronic mail system, belong to Invesco and not to the Covered Person. They are not intended to be used for amusement, solicitation, or other non-business purposes. While it is recognized that Covered Persons will occasionally use the system for personal communications, it is expected that such uses will be kept to a minimum and that Covered Persons will be responsible and professional in their use of e-mail. The use of the computer systems to make or forward derogatory or offensive remarks about other people or groups is prohibited. E-mail messages should be treated as any other written business communication.

22. Invesco Intellectual Property

Employees and officers must carefully maintain and manage the intellectual property rights of Invesco, including patents, trademarks, copyrights and trade secrets, to preserve and protect their value. Information, ideas and intellectual property assets of Invesco are important to the company's success.

Invesco's name, logo, trademarks, inventions, processes and innovations are intellectual property assets and their protection is vital to the success of the company's business. The company's and any of its subsidiaries' names, logos and other trademarks and service marks are to be used only for authorized company business and never in connection with personal or other activities unless appropriately approved and in accordance with company policy. In addition, our Covered Persons must respect the intellectual property rights of third parties. Violation of these rights can subject both you and the company to substantial liability, including criminal penalties.

Page 15 of 23

Any work product produced in the course of performing your job shall be deemed to be a "work made for hire" and shall belong to Invesco and is to be used only for the benefit of Invesco. This includes such items as marketing plans, product development plans, computer programs, software, hardware and similar materials. You must share any innovations or inventions you create with your supervisor so that the company can take steps to protect these valuable assets.

23. Integrity and Accuracy of Financial Records

The preparation and maintenance of accurate books, records and accounts is required by law and essential to the proper discharge of financial, legal and reporting obligations. All Covered Persons are prohibited from directly or indirectly falsifying or causing to be false or misleading any financial or accounting book, record or account. In addition, all financial data must be completely and accurately recorded in compliance with applicable law and Invesco's accounting policies and procedures. A Covered Person may violate this section by acting or by failing to act when he or she becomes aware of a violation or potential violation of this section.

24. Disclosure in Reports and Documents.

Filings and Public Materials. As a public company, it is important that the company's filings with UK authorities, the United States Securities and Exchange Commission (the "SEC") and other U.S. federal, state, domestic and international regulatory agencies are full, fair, accurate, timely and understandable. The company also makes many other filings with the SEC and other UK, U.S. and international regulatory agencies on behalf of the funds that its subsidiaries and affiliates manage. Further, the company prepares mutual fund account statements, client investment performance information, prospectuses and advertising materials that are sent out to its mutual fund shareholders and clients.

Disclosure and Reporting Policy. The company's policy is to comply with all applicable disclosure, financial reporting and accounting regulations applicable to the company. The company maintains the highest commitment to its disclosure and reporting requirements, and expects and requires all Covered Persons to record information accurately and truthfully in the books and records of the company.

Information for Filings. Depending on his or her position with the company, a Covered Person may be called upon to provide necessary information to assure that the company's public reports and regulatory filings are full, fair, accurate, timely and understandable. The company expects all Covered Persons to be diligent in providing accurate information to the inquiries that are made related to the company's public disclosure requirements.

Disclosure Controls and Procedures and Internal Control Over Financial Reporting. Covered Persons are required to cooperate and comply with the company's disclosure

Page 16 of 23

controls and procedures and internal controls over financial reporting so that the company's reports and documents filed with the UK authorities, the SEC and other U.S. federal, state, domestic and international regulatory agencies comply in all material respects with applicable laws, and rules and regulations, and provide full, fair, accurate, timely and understandable disclosure.

25. Improper Influence on the Conduct of Audits

Every Covered Person must deal fairly and honestly with outside accountants performing audits, reviews or examinations of Invesco's and its subsidiaries' financial statements. To that end, no Covered Person of Invesco may make or cause to be made a materially false or misleading statement (or omit facts necessary to make the statements made not misleading) in connection with an audit, review or examination of financial statements by independent accountants or the preparation of any document or report required to be filed with a governmental or regulatory authority. Covered Persons of Invesco also are prohibited from coercing, manipulating, misleading or fraudulently inducing any independent public or certified public accountant engaged in the performance or review of financial statements that are required to be filed with a governmental or regulatory authority if he or she knows or should have known that his or her actions could result in making those financial statements materially misleading.

26. Standards for Invesco's Financial Officers

Invesco's Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer (the "Financial Officers") are required to take all reasonable steps to provide full, fair, accurate, timely and understandable disclosures in the reports and documents that Invesco files with or submits to the SEC and other regulatory bodies and in other public communications made by Invesco. In the event that a Financial Officer learns that any such report, document or communication does not meet this standard and such deviation is material, then the Financial Officers are required to review and investigate such deviation, advise the Board of Directors or the Audit Committee of the Board of Directors regarding the deviation and, where necessary, revise the relevant report, document or communication.

Although a particular accounting treatment for one or more of Invesco's operations may be permitted under applicable accounting standards, the Financial Officers may not authorize or permit the use of such an accounting treatment if the effect is to distort or conceal Invesco's true financial condition. The accounting standards and treatments utilized by Invesco must, in all instances, be determined on an objective and uniform basis and without reference to a single transaction or series of transactions and their impact on Invesco's financial results for a particular time period. Any new or novel accounting treatment or standard that is to be utilized in the preparation of Invesco's financial statements must be discussed with Invesco's Audit Committee and its independent auditors.

Page 17 of 23

27. Policy and Procedures on Reporting Potential Material Violations

Invesco's Audit Committee has adopted the following statement of policy with respect to the reporting by employees of potential material violations of this Code of Conduct, laws or regulations and our related non-retaliation policy:

"Invesco strives to ensure that all activity by or on behalf of Invesco is in compliance with applicable laws, rules and regulations. Invesco and its employees must adhere to the highest standards of honest and ethical conduct. Employees of Invesco and its subsidiaries are affirmatively required to report possible violations of the Invesco Code of Conduct, laws or regulations promptly to their manager, a Human Resources Director at the employee's site, the employee's Legal and Compliance Department representative, or via the 24-hour toll-free, anonymous Invesco Compliance Reporting Line.

Invesco will not permit retribution, harassment, or intimidation of any employee who in good faith reports a possible violation. Specifically, Invesco policy prevents any employee from being subject to disciplinary or retaliatory action by Invesco or any of its employees or agents as a result of the employee's good faith:

- Disclosing information to a government or law enforcement agency, where the employee has reasonable cause to believe that the information discloses a violation or possible violation of federal or state law or regulation; or

- Providing information, causing information to be provided, filing, causing to be filed, testifying, participating in a proceeding filed or about to be filed, or otherwise assisting in an investigation or proceeding regarding any conduct that the employee reasonably believes involves a violation of: (1) any criminal law relating to securities fraud, mail fraud, bank fraud, or wire, radio, television or internet fraud; (2) any rule or regulation of the United States Securities and Exchange Commission or any other national, state or provincial securities regulatory authority; or any provision of applicable law relating to fraud against shareholders, where, with respect to investigations, such information or assistance is provided to or the investigation is being conducted by a national, state or provincial regulatory agency, a member of any parliamentary body, or a person at Invesco with supervisory or similar authority over the employee.

However, employees who file reports or provide evidence which they know to be false or without a reasonable belief in the truth and accuracy of such information will not be protected by the above policy statement and may be subject to disciplinary action, including termination of their employment."

If you are a Covered Person with complaints or concerns regarding:

(i) violations of this Code of Conduct or the rules mentioned herein;

Page 18 of 23

(ii) violations of laws or regulations generally involving Invesco; or

(iii) questionable accounting matters, internal accounting controls, auditing matters, breaches of fiduciary duty or violations of United States or foreign securities laws or rules (collectively "Accounting Matters"), including:

- fraud or deliberate error in the preparation, evaluation, review or audit of any financial statement of Invesco;

- fraud or deliberate error in the recording and maintaining of financial records of Invesco;

- deficiencies in or non-compliance with Invesco's internal accounting controls;

- misrepresentation or false statements to or by a senior officer or accountant regarding a matter contained in the financial records, financial reports or audit reports of Invesco;

- deviation from full and fair reporting of Invesco's financial condition; or

- fraudulent or criminal activities engaged in by officers, directors or employees of Invesco;

you may report your concerns in any of three ways:

YOU CAN SPEAK WITH YOUR SUPERVISOR. We encourage you to first contact your immediate supervisor, who is in turn responsible for informing Invesco's Compliance Reporting Line (described below) of any concerns raised.

YOU CAN SPEAK DIRECTLY WITH THE BUSINESS UNIT OR DIVISIONAL GENERAL COUNSEL. If you prefer not to discuss a concern with your own supervisor, you may instead contact the General Counsel of your business unit or division directly. You are also free to e-mail the business unit or divisional General Counsel at the appropriate e-mail address. Such person will then likewise be responsible for informing Invesco's Compliance Reporting Line (described below) of any concerns raised.

YOU CAN CALL OUR COMPLIANCE REPORTING LINE. You may also call the Invesco Compliance Reporting Line. If you are calling from a U.S. or Canadian location dial 1-866-297-3627. For calls from all other locations, dial an international operator and request a collect call to 1-704-943-1136. When asked for your name use "Invesco." You can use the Compliance Reporting Line to report possible violations or to check on the status of a previously filed report. You can also report to the Compliance Reporting Line if you believe that a report previously made to company management, your

Page 19 of 23

supervisor, other management personnel or the applicable business unit or divisional General Counsel has not been addressed.

The Compliance Reporting Line is administered by an outside vendor. The telephone operators for the Compliance Reporting Line have been trained to receive your call. The Compliance Reporting Line is available 24 hours a day, seven days a week. All calls will be answered by a live person. Calls are not recorded and are not able to be traced. You have the option to remain anonymous. If you remain anonymous, you will be given a numeric code so that you may call back and ask for follow up. You will be guided through the call and prompted by appropriate questions from the operator. You will be given a date on which you can call back and receive a follow up report. Once the call is completed, a report will be generated and sent to the appropriate departments within Invesco based on the subject matter of your call. You are urged to call back for follow up, because in the event more information is required, this will be an opportunity for you to provide those details.

If you report a possible violation, regardless of the method that you use to make the report, it is important that you provide as much detail as possible, including names, dates, times, locations and the specific conduct in question. Only with sufficient specific information can Invesco adequately investigate the reported action.

Your submission of information will be treated in a confidential manner to the extent reasonably possible. Please note, however, that if an investigation by Invesco of the activities you have reported takes place, it may be impossible for Invesco to maintain the confidentiality of the fact of the report or the information reported.

Complaints relating to Accounting Matters will be reviewed under Audit Committee direction and oversight by such persons as the Audit Committee determines to be appropriate. All other matters will be reviewed under the direction and oversight of the appropriate departments within Invesco, usually also including the Legal & Compliance Department. Prompt and appropriate corrective action will be taken when and as warranted in the judgment of the Audit Committee or other reviewing department.

28. Disclosure; Amendments

To the extent required by law, the company shall publicly (e.g., in its Annual Report on Form 20-F and/or on its website) disclose this Code of Conduct and its application to all of the company's Covered Persons.

Page 20 of 23

This Code may only be amended by Invesco's Board of Directors or a duly authorized committee thereof. To the extent required by law, amendments to the Code of Conduct shall be disclosed publicly. As set forth in Item 16B of the company's Annual Report on Form 20-F for 2005 filed with the SEC, the company has elected to disclose certain amendments to the Code that affect, and any waivers of the Code granted to, Financial Officers on the company's Web site in accordance with the requirements of Instruction 4 to Item 16B.

29. Waivers of the Code.

a. Waivers for Executive Officers. Any change in or waiver of this Code for executive officers (as defined in Rule 3b-7 under the Securities Exchange Act of 1934, "Executive Officers") of the company may be made only by the Board of Directors or a committee thereof in the manner described in Section 29(d) below, and any such waiver (including any implicit waiver) shall be promptly disclosed to shareholders as required by the corporate governance listing standards of the New York Stock Exchange and other applicable laws, rules and regulations.

b. Waivers for Other Covered Persons. Any requests for waivers of this Code for Covered Persons other than Executive Officers of the company may be made to the Legal and Compliance Department in the manner described in Section 29(e) below.

c. Definition of Waiver. For the purposes of the Code, the term "waiver" shall mean a material departure from a provision of the Code. An "implicit waiver" shall mean the failure of the company to take action within a reasonable period of time regarding a material departure from a provision of the Code that has been made known to an Executive Officer.

d. Manner for Requesting Executive Officer Waivers.

i. Request and Criteria. If an Executive Officer wishes to request a waiver of this Code, the Executive Officer may submit to the Global Compliance Director or the Legal and Compliance Department a written request for a waiver of the Code only if he/she can demonstrate that such a waiver:

A. is necessary to alleviate undue hardship or in view of unforeseen circumstances or is otherwise appropriate under all the relevant facts and circumstances;

B. will not be inconsistent with the purposes and objectives of the Code;

C. will not adversely affect the interests of clients of the company or the interests of the company; and

Page 21 of 23

D. will not result in a transaction or conduct that would violate provisions of applicable laws or regulations.

ii. Discretionary Waiver and Response. The Legal and Compliance Department will forward the waiver request to the Board of Directors or a committee thereof for consideration. Any decision to grant a waiver from the Code shall be at the sole and absolute discretion of the Board of Directors or committee thereof, as appropriate. The Company Secretary will advise the Legal and Compliance Department in writing of the Board of Director's decision regarding the waiver, including the grounds for granting or denying the waiver request. The Legal and Compliance Department shall promptly advise the Executive Officer in writing of the Board of Director's decision.

e. Manner for Requesting Other Covered Person Waivers.

i. Request and Criteria. If a Covered Person who is a non-Executive Officer wishes to request a waiver of this Code, such Covered Person may submit to the Legal and Compliance Department a written request for a waiver of the Code only if he/she can demonstrate that such a waiver would satisfy the same criteria set forth in Section 29(d).

ii. Discretionary Waiver and Response. The Legal and Compliance Department shall forward the waiver request to the General Counsel of the company for consideration. The decision to grant a waiver shall be at the sole and absolute discretion of the General Counsel of the company. The General Counsel will advise the Legal and Compliance Department in writing of his/her decision regarding the waiver, including the grounds for granting or denying the waiver request. The Legal and Compliance Department shall promptly advise the Covered Person in writing of the General Counsel's decision.

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

CONCLUSION

As Covered Persons, each of us is obligated to read and understand this Code of Conduct and our relevant business unit's policies and procedures. No code of conduct, however, can address every situation for which guidance may be necessary. If you are unclear about a situation, stop and ask for guidance before taking action. All Covered

Page 22 of 23

Persons are expected to abide by both the letter and spirit of this Code. Covered Persons are also expected to perform their work with honesty and integrity in any areas not specifically addressed by the Code. Invesco will investigate reported violations of the Code and, if violations are found, may take disciplinary action, if appropriate, against the individuals involved, and may make reports, if appropriate, to civil, criminal or regulatory authorities. Nothing in this Code restricts the company from taking any disciplinary action on any matters pertaining to the conduct of a Covered Person, whether or not expressly set forth in the Code. Any questions regarding the scope or interpretation of this Code should be referred to the appropriate Compliance or Legal officer.

AIM TRIMARK INVESTMENTS
ADDENDUM TO THE
AMVESCAP CODE OF CONDUCT

EFFECTIVE DATE: OCTOBER 1, 2006 REVISED DATE: APRIL 2, 2007

1. INTRODUCTION

Every employee of AIM Trimark Investments ("AIM Trimark") is considered an employee of AMVESCAP PLC and is subject to the AMVESCAP Code of Conduct ("AMVESCAP Code"). All officers, directors and employees of AIM Trimark, including temporary, part-time, contract, and seasonal personnel, are expected to be familiar with the AMVESCAP Code and this Addendum and are required to provide an annual certificate accepting the AMVESCAP Code and this Addendum and acknowledging the obligation to abide by their terms.

The AMVESCAP Code has general application globally. It cannot address specific circumstances which may be required by local regulation or custom. This Addendum, together with the other Policies referred to below, is intended to provide supplementary guidance and more detailed procedures where needed to give effect to the AMVESCAP Code for AIM Trimark employees. The other AIM Trimark policies which deal directly and in a general manner with employee conduct include:

- AIM Trimark Personal Trading Policy -- Policy D-7

- Personal Conflicts and Self-Dealing- Policy B-10

- Gifts and Entertainment - Policy D-6

- Corporate Systems Policies

2. FIDUCIARY OBLIGATIONS

In AIM Trimark's capacity as a money manager, AIM Trimark stands in a fiduciary relationship to its clients. Those clients to whom the fiduciary obligations are owed are the mutual funds and investment accounts that we manage, and the holders of fund securities or the clients in the investment accounts, as applicable. (For purposes of this Addendum, the terms "clients" and "client accounts" always refers to the investment funds that we manage or sub-advise or other accounts in respect of which AIM Trimark has been engaged to provide money management services, and do not refer to business partners who distribute our products.)

In carrying out our investment management responsibilities, AIM Trimark must at all times act honestly, in good faith and in the best interests of our clients. This means that the interests of our clients must always and in every instance come ahead of the interests of AIM Trimark or AMVESCAP or of any personal interest of an employee.

The fiduciary nature of our business means that our actions and our policies are governed by the principles of:

- TRANSPARENCY: it is not enough that AIM Trimark put client interests ahead of our own interests; but rather, we must be seen to do so, and the appearance of conflicts is to be avoided where possible


- ACCOUNTABILITY: AIM Trimark must account to our clients as to how we manage their money, through appropriate and clear reporting and disclosure

- COMPETENCE: AIM Trimark must act competently and with the appropriate level of care, skill and diligence in the management of client funds.

Regard shall be had to these principles in the interpretation and application of the AMVESCAP Code, this Addendum and related policies and procedures.

3. AIM TRIMARK PERSONAL TRADING POLICY

Policy D-7, AIM Trimark Personal Trading Policy, covers the following topics in detail and should be referred to for the definitive rules in this regard.

3.1 RESTRICTION ON THE PERSONAL TRADING ACTIVITY OF AIM TRIMARK EMPLOYEES

Employees of AIM Trimark may not engage in a personal securities transaction unless it has been pre-cleared by the AIM Trimark Compliance department following a determination that the transaction does not give rise to an actual or potential conflict of interest with activity by a client account in the same security. Employees are required to report transactions and holdings to the AIM Trimark Compliance department on a regular basis. The pre-clearance and reporting requirements also apply to Covered Accounts. Covered Accounts are accounts which an Employee is financially interested in or controls, and may include (but are not limited to) accounts of a spouse, minor child, relative, friend or personal business associate.

4. PERSONAL CONFLICTS OF INTEREST

4.1 UNDERLYING PRINCIPLE

Employees must avoid taking any actions or placing themselves in circumstances that result in an actual or potential conflict between their own personal interests and the interests of AIM Trimark, AMVESCAP or client accounts. Employees must never profit personally at the expense of AIM Trimark, AMVESCAP or client accounts, and they must refrain from deliberately or knowingly doing things which may be otherwise detrimental to the interests of AIM Trimark, AMVESCAP or client accounts.

Policy D-7, AIM Trimark Personal Trading Policy, and Policy B-10, Personal Conflicts and Self-Dealing, cover certain of the following topics in detail and should be referred to for the definitive rules in that regard.

4.2 POSSESSION OF INSIDE INFORMATION

Any director, officer or employee who possesses or believes that he or she may possess material undisclosed or non-public information about any issuer of securities which could put such person in a conflict of interest with AIM Trimark or any of our client accounts must report the matter immediately to the AIM Trimark Chief Compliance Officer (or designee), who will review the matter and provide further instructions as to the appropriate handling of the information.

4.3 INSIDER TRADING & TIPPING

Trading on or communicating, other than to persons with a need to know, material non-public information, or inside information, of any sort, whether obtained in the course of research activities, through a client relationship or otherwise, is strictly prohibited. AIM Trimark forbids its directors and employees from trading, either personally or on behalf of others (including client accounts managed by AIM Trimark), on material non-public information or communicating material non-public information to others in violation of the law. The communicating or passing on of this type of information is sometimes known as "tipping" and trading on such information is "insider trading".

4.4 PERSONAL TRADING

Personal securities transactions of all Employees of AIM Trimark are subject to restrictions and pre-clearance, as discussed above. Personal securities transactions of independent directors of AIM Trimark's corporate funds and members of the AIM Trimark Fund Advisory Boards are not subject to the pre-clearance or reporting requirements, except with respect to trading in the securities of AMVESCAP or shares of any closed-end investment company or investment trust on which such independent director may serve in a director or trustee capacity.

4.5 SHORT TERM TRADING IN MUTUAL FUNDS AND SEG FUNDS

Employees are prohibited from engaging in excessive short-term trading in any investment fund or similar investment vehicle (including segregated funds and variable annuity products) for which AIM Trimark is the manager or investment advisor or in which an AIM Trimark fund is an ingredient, in the case of fund-of-fund products. Determination of behaviour constituting "excessive short-term trading" will be as set out in Policy D-4, Market Timing.

4.6 PERSONAL BORROWING AND LENDING

Except with the prior written approval of the AIM Trimark Compliance department, employees may not borrow from or lend personal funds or other personal property to any customer of AIM Trimark or third party vendor who has a business relationship or potential business relationship with AIM Trimark. This prohibition does not operate to prohibit employees borrowing from recognized financial institutions such as banks, trust companies and credit card companies with whom AIM Trimark does or may do business.

4.7 OUTSIDE ACTIVITIES

Employees may not undertake or engage in a business activity that is in competition or in conflict with AIM Trimark's business unless they have received the written consent of the employee's manager and the approval of the AIM Trimark Compliance department. For this purpose, "undertaking or engaging in a business activity" includes any direct or indirect involvement with an enterprise for which the employee

3

may receive financial compensation or return. A business will be deemed to be in competition or conflict with AIM Trimark if the business offers or provides products or services of a type similar to products or services offered by AIM Trimark or AMVESCAP. This prohibition does not operate to prohibit employees from making personal investments in public issuers that are in a similar business to AIM Trimark or AMVESCAP.

In addition, all Employees of AIM Trimark are prohibited from serving as directors/trustees of organizations (including charitable organizations) except with the prior written approval of AIM Trimark's President and Chief Executive Officer. All such requests must be submitted to the AIM Trimark Compliance department for consideration prior to submission to AIM Trimark's President and Chief Executive Officer.

4.8 DUAL REGISTRATION

Employees who are registered with a securities regulatory authority as a representative or officer of both AIM Funds Management Inc. and AIM Mutual Fund Dealer Inc. have duties and responsibilities equally to both registered entities. Dually registered employees must allocate sufficient time to support each entity and take into consideration the impact on both entities when making policy decisions. Dually registered employees must disclose in writing to their clients, at account opening and on an annual basis, the fact that the employee is registered with both AIM Funds Management Inc. and AIM Mutual Fund Dealer Inc. and that there are policies and procedures in place to minimize the potential for conflicts of interest resulting from the dual registration.

Employees licensed by any regulatory or professional body, are expected to adhere to any requirements imposed by those entities. Except with the prior written consent of the Chief Compliance Officer, no employee may be licensed or registered with, or as a representative of, any entity other than AIM Funds Management Inc. and AIM Mutual Fund Dealer Inc. This includes but is not limited to securities dealers, scholarship plan dealers, insurance agents, real estate agents, mortgage brokers and other similar entities.

5. POLITICAL CONTRIBUTIONS AND ACTIVITY

Employees, as private citizens, should feel free to exercise their rights and duties in any political or civic process.

AIM Trimark however, does not make political contributions nor does AIM Trimark participate in political activities, at any level of government. AIM Trimark does not make corporate donations to any political party or cause. For example:

- no purchases of seats or tables at fundraising events

- no contributions to political parties or candidate campaigns (includes local or municipal politics)

- no use of AIM Trimark resources (e.g. photocopying, printing, use of office space) in aid of political activity

No employee may make any such political contributions on behalf of AIM Trimark. Employees should be careful not to give the impression that personal political views and beliefs are those of AIM Trimark.

Any departure from the foregoing must receive the prior approval of the AIM Trimark Compliance department.

Gifts and Entertainment

Policy Number: D-6 Effective Date: March 2006 Revision Date: April 2007


OVERVIEW

AMVESCAP has in place the AMVESCAP Gifts and Entertainment Policy which is applicable to AMVESCAP and its individual business units worldwide. This AIM Trimark Gifts and Entertainment Policy ("Policy") is intended to work with the AMVESCAP Policy and supplement it with local rules.

All AIM Trimark employees, including temporary, part-time, contract, and seasonal personnel, must refrain from conduct that could give rise to the appearance of a conflict of interest. The provision or receipt of gifts or entertainment can create, or can have the appearance of creating, conflicts of interest.

Employees also need to take into consideration the firm's policy on corporate expenses, which can be found on Total Access Point ("TAP") under travel and entertainment guidelines, and the firm's policy on Sales Practices, which can be found in the AIM Trimark compliance manual under section D-2.

DEFINITIONS

For purposes of this Policy, a GIFT is anything of value given or received involving AIM Trimark personnel, and a person or entity that has a direct or indirect, existing or potential business relationship with AIM Trimark (a "Business Partner"). This Policy also applies to gifts given by AIM Trimark to family members of a Business Partner and gifts received from a Business Partner by a family member of an employee of AIM Trimark. Business Partners specifically include broker dealers and financial advisors. Gifts may include, but are not limited to, personal items, air miles, services, office accessories, electronic equipment (e.g., iPods, MP3s, etc.), tickets (e.g., theatre, concerts, sporting events, etc.) and sporting equipment (e.g., golf clubs, tennis rackets, etc.). For purposes of this Policy, gifts also include charitable contributions and sponsorship requests (e.g., sponsoring a minor hockey team) made to or at the request of a Business Partner. For purposes of this Policy, gifts do not include promotional items of nominal value (approximately $20 - e.g., golf balls, pens, etc.) that display the logo of AIM Trimark or its AMVESCAP business units, or of its Business Partners.

ENTERTAINMENT involves attendance at activities, including but not limited to meals, sporting events, the theatre, parties or receptions, and similar functions. Entertainment requires the presence of both AIM Trimark personnel and Business Partner personnel;


unless personnel from both entities attend, the activity constitutes a gift. The value of entertainment includes the cost of the activity itself (for example, the cost of tickets or a meal), as well as the cost of any related activities or services provided (such as prizes). The value of entertainment does not include the cost of overhead (such as rent or equipment rentals).

THRESHOLDS

Employees are prohibited from giving or receiving gifts with a value of more than $250.

Entertainment should not exceed $450 per business partner.

FREQUENCY

Gifts and entertainment cannot be so extensive or so frequent as to cause a reasonable person to question whether the provision of the items or activity improperly influences the employee or Business Partner.

The maximum total value of gifts received by, or given to, a business partner is $250 annually.

Entertainment is limited to three times per year per business partner.

PROHIBITED ACTIVITIES

Employees are prohibited from providing or receiving any gift or entertainment that is conditioned upon AIM Trimark doing business with the entity or person involved.

Employees are prohibited from soliciting gifts and entertainment. Employees are to immediately advise the AIM Trimark Compliance department if a Business Partner solicits the employee for gifts and entertainment other than a charitable donation or request for sponsorship.

Except with the prior approval of the AIM Trimark Compliance department, employees cannot pay for, or accept, any travel and/or accommodation to or from a Business Partner.

With respect to approved co-operative marketing practices, such as sales communications and investor seminars, where AIM Trimark pays a portion of the cost, AIM Trimark cannot provide gifts, other than nominal valued promotional items, to the dealer's clients. Nominal speaker gifts would be co-op eligible at approved dealer-sponsored events for financial advisors.

REPORTING/RECORD KEEPING


Each department or employee is responsible for keeping a record of all gifts and entertainment given or received. Minimum required information includes: date, employee name(s), business partner firm name, business partner representative name(s), description of gift or entertainment, approximate dollar value, and required approval where applicable. Promotional items of nominal value (approximately $20) and department breakfasts or lunches do not need to be recorded. Where the value of the activity or item is not readily known, the employee should record the estimated cost.

REVIEW AND MONITORING

This Policy shall be overseen and administered by AIM Trimark's Code of Ethics Committee, which has responsibility for the overall scope, application, and enforcement of this Policy. AIM Trimark's Code of Ethics Committee shall receive the reports and recommendations of the AIM Trimark Compliance department and of management from time to time and periodically update or revise this Policy as may be desirable.

Each department head is expected to review the gifts and entertainment log on a regular basis in order to identify any concerns or trends. Any concerns or issues are to be brought to the attention of the AIM Trimark Compliance department.

The AIM Trimark Compliance department will conduct a quarterly review of the gifts and entertainment log. A summary of such review, together with other relevant observations and recommendations, shall be reported to the AIM Trimark Code of Ethics Committee.

Evidence of reviews must be maintained for a minimum of seven years.



D7. AIM TRIMARK PERSONAL TRADING POLICY

Policy Number: D-7 Effective Date: October 2006 Revision Date: March 2007


1. PURPOSE AND APPLICATION

The AIM Trimark Personal Trading Policy applies to all officers, directors and employees of AIM Trimark Investments, including temporary, part-time, contract, and seasonal personnel (collectively referred to as "Employee"). For purposes of this Policy, the terms "clients" and "client accounts" always refers to the investment funds that AIM Trimark manages or sub-advises or other accounts in respect of which AIM Trimark has been engaged to provide money management services.

The purpose of this Policy is to ensure the fair treatment of client accounts through the highest standard of integrity and ethical business conduct by Employees. The Policy is designed to ensure, among other things, that the personal securities transactions of all Employees are conducted in accordance with the following general principles:

- A duty at all times to place the interests of client accounts first.

- The requirement that all personal securities transactions be conducted in a manner that avoids any actual or potential conflict of interest or the appearance of a conflict of interest.

- That Employees should not take otherwise inappropriate advantage of their positions.

Employees must not use any non-public information about client accounts for their direct or indirect personal benefit or in a manner that would not be in the best interests of client accounts. Employees also must not use their position to obtain special treatment or investment opportunities not generally available to client accounts or the public.

The personal trading requirements pertaining to pre-clearance, reporting and investment restrictions contained in this Policy apply to both Employees and their Covered Accounts.

AIM Trimark recognizes that certain relationships with non-employees may, from time to time, present particular risks that inappropriate trading could occur. Those risks may be present, for example, through certain arrangements with consultants or independent contractors who have entered into long-term services arrangements with AIM Trimark pursuant to which they are expected to have access to non-public information in connection with those arrangements (such information may relate to AIM Trimark or some outside source, and may be obtained from AIM Trimark or some outside source). Accordingly, as part of the process for engaging the services of consultants or other independent contractors, the AIM Trimark Chief Compliance Officer shall take such


steps as may be reasonably determined to be necessary or appropriate. Those steps may or may not include requiring a non-employee to agree to be bound by these procedures as if he or she were an Employee.

2. DEFINITIONS

2.1 EMPLOYEE

For the purposes of this Policy the term Employee includes all officers, directors and employees of AIM Trimark Investments including temporary, part-time, contract, and seasonal personnel

2.2 COVERED ACCOUNTS

A Covered Account is defined for purposes of this Policy as any account:

- In which an Employee has a direct or indirect financial interest;

- Over which such Employee has direct or indirect control over the purchase or sale of securities; or

- In which securities are held for an Employee's direct or indirect benefit.

Such Covered Accounts may include, but are not limited to, accounts of a spouse, minor child, relative, friend or personal business associate.

3. PRE-CLEARANCE REQUIREMENTS

3.1 SUBMITTING THE REQUEST TO TRADE

Except where noted below, an Employee must receive the prior approval using the automated review system (Star Compliance) or from the AIM Trimark Compliance department in order to engage in a personal securities transaction. The Star Compliance system will review the trade request to determine whether or not the proposed transaction gives rise to an actual or potential conflict of interest with activity in a client account in the same security. Upon completion of the review process, the Employee will receive a time stamped response indicating whether the trade is authorized or denied.

Pre-clearance will not be given if there has been a transaction by a subject client account in the same, or equivalent, security within seven (7) calendar days of the proposed personal securities transaction (the "7-Day Rule"). An equivalent security means a security that (1) is convertible into another security or (2) gives its holder the right to purchase another security of the same issuer. For example, a bond or preferred stock may be convertible into another security of the same issuer, or an option or warrant may give the holder the right to purchase stock of the same issuer. ADR and EDR shares are considered equivalent to their corresponding foreign shares.

The trade approval process involves the following steps:


- A trade must be entered into the Star Compliance system.

- The Star Compliance system will confirm that there is no activity currently on the trading desk for the security involved in the proposed personal transaction and check the portfolio accounting system to verify that there have been no transactions for the requested security within seven calendar days.

- The Star Compliance system will provide an automated response on a timely basis for all pre-approval requests indicating whether the transaction has been approved or denied.

3.2 EXECUTING APPROVED TRANSACTIONS

Except as may be authorized by the Chief Compliance Officer or designate in the case of certain securities or classes of securities, all authorized personal securities transactions must be executed by the next business day. If the trade is not executed within this time period, a new pre-clearance request must be submitted.

Employees will be requested to reverse any trades processed without the required pre-approval. Any costs or losses associated with the reversal are the responsibility of the Employee.

3.3 EXCEPTIONS TO PRE-CLEARANCE REQUIREMENTS

Employees may trade in the following types of securities without regard to the pre-clearance procedures:

- Open-end mutual funds, open-end unit investment trusts and pooled trust funds (whether or not managed or distributed by an AMVESCAP Company).

- Variable annuities, variable life products, segregated funds, and other similar unit-based insurance products issued by insurance companies and insurance company separate accounts.

- Securities issued or guaranteed by the Government of Canada, or the government of any province in Canada.

- Securities issued or guaranteed by the Governments of the United States, United Kingdom, Germany, Japan, France and Italy.

- Guaranteed Investment certificates, bank certificates of deposit other deposits with financial institutions, bankers acceptances, commercial paper and high quality short-term instruments, including repurchase agreements.


- Short-term debt securities maturing in less than 91 days from their date of issue.

- Physical commodities or securities relating to those commodities.

- Other securities or classes of securities as the Committee may from time to time designate.

Employee accounts excluded from the pre-clearance requirement are the following:

- Employee share purchase plans except for the sale of the securities.

- Employee stock option purchase plans except for the sale of the securities.

- Accounts capable of holding only deposits or GIC's issued by a financial institution and/or mutual funds.

- Fully-managed discretionary accounts subject to the conditions in 3.4 below.

3.4 MANAGED ACCOUNTS

To qualify as a fully-managed discretionary account, the account must be fully "discretionary", without any influence by the Employee over individual transactions. This means that full investment discretion has been granted to an investment manager or trustee and that neither the Employee nor Covered Account person participates in the investment decisions or is informed in advance of transactions in the account. Pre-clearance is not required for transactions in a Covered Account in which an Employee is not exercising power over investment discretion including a managed account, provided that:

- The account is the subject of a written contract providing for the delegation by the Employee of substantially all investment discretion to another party.

- The Employee has provided the AIM Trimark Compliance department with a copy of such written agreement.

- The Employee certifies in writing that he or she has not discussed, and will not discuss, potential investment decisions with the party to whom investment discretion has been delegated.

- The Employee otherwise complies with the annual reporting requirement contained herein, and also provides or makes provision for the delivery to the AIM Trimark Compliance department of periodic statements of discretionary account holdings.


- The foregoing exception from the pre-clearance requirement does not apply to transactions by a delegated discretionary account in shares of AMVESCAP. All employees are required to notify parties to whom they have delegated investment discretion that such discretion may not be exercised to purchase shares of AMVESCAP and that any sales of AMVESCAP shares by a Covered Account that is the subject of delegated investment discretion are subject to the pre-clearance and reporting requirements.

- Discretionary managed accounts for which this exemption is available would not include ones where the accountholder has given a power of attorney (POA) to another person such as a broker for occasional discretionary trading. Discretionary accounts would include blind trusts.

4. OPTIONS TRADING

In the case of personal securities transactions involving the purchase or sale of an option on an equity security, the Star Compliance system will determine whether to authorize the transaction by matching the pre-clearance request against activity in client accounts in both the option and the underlying security. This determination will not be made, and pre-clearance will not be given, if there has been a client account transaction in either the option or the underlying security within 7 calendar days of the proposed personal securities transaction. Pre-clearance is required for both the opening and closing transaction.

It is the responsibility of the employee to be aware of the additional risks that can result from engaging in certain transactions. For example, if an opening options transaction is approved, the closing options transaction may not be approved or may be delayed in certain cases due to actual or apparent conflicts of interest or competing obligations that arise after the time the employee's opening transaction was approved. An employee is prohibited from purchasing or selling options on shares of AMVESCAP.

5. SHORT SALES

Short sales of securities are permissible subject to the following conditions:

- No short sales on AMVESCAP

- No short sales on securities where there has been a trade in the same security within the last 7 days in one of the client accounts

- Employees are prohibited from short-term trading; therefore, the Employee is restricted from buying back the position within 60 days.

- Portfolio managers are prohibited from short selling a security if the client account the Portfolio Manager manages are long the security.


- If a Portfolio Manager is selling a stock there should generally be no "short selling" allowed until that position is completely sold. This provision includes the situation where the Portfolio Manager stops selling the security for a short period, for example to let the market absorb what has been sold, and then resumes selling the position. If other client accounts hold the same security, the AIM Trimark Compliance department will review the other client accounts to determine if the other client accounts are active in the security or are going to be active.

6. RESTRICTIONS ON CERTAIN ACTIVITIES

In order to avoid even the appearance of conduct that might be deemed contrary to a client's best interests, Employees are subject to the following additional restrictions and prohibitions relating to certain investment activities and related conduct as set out herein.

6.1 PROHIBITION AGAINST TRADING IN SECURITIES ON "RESTRICTED LISTS"

It is recognized that there may be occasions when AMVESCAP, an AMVESCAP Company, or an Employee who is a key executive of AMVESCAP or an AMVESCAP Company, may have a special relationship with an issuer of securities. In such occasions the Board of Directors of AMVESCAP or the Code of Ethics Committee may decide to place the securities of such issuer on a "restricted list", to be maintained by the Chief Compliance Officer. Employees are prohibited from engaging in any personal securities transactions in a security on a "restricted list".

6.2 PROHIBITION AGAINST SHORT-TERM TRADING ACTIVITIES

Employees are prohibited from profiting from a trade in an "opposite transaction" in the same, or equivalent, security within 60 days of its purchase or sale. This short-term trading prohibition may be waived by the AIM Trimark Compliance department in certain instances including where an employee wishes to limit his or her losses on a security with rapidly depreciating market value. Such circumstances must be disclosed at the time pre-clearance is requested.

6.3 PROHIBITION AGAINST PURCHASES IN INITIAL PUBLIC OFFERINGS

Employees generally are prohibited from purchasing securities in IPOs. Employees who are not investment personnel and whose proposed IPO trade is through discretionary accounts may acquire shares in an IPO. Investment personnel are prohibited from purchases in Initial Public Offerings, even if the proposed IPO trade would be through a discretionary account, unless the person has obtained pre-clearance by the Chief Compliance Officer and Chief Investment Officer.

6.4 RESTRICTED SECURITIES ISSUED BY PUBLIC COMPANIES

Generally, Employees are discouraged from investing in restricted securities of public companies including special warrant deals. Restricted securities are securities acquired in an unregistered, private sale from an issuer. An Employee may purchase such securities, however, if such purchase has been pre-cleared by the AIM Trimark Compliance


department following a determination that the proposed transaction does not present any actual or potential conflict of interest.

6.5 RESTRICTIONS ON PRIVATE PLACEMENTS (INCLUDING HEDGE FUNDS)

An Employee may not purchase or sell any security (e.g., stock, bond or limited partnership interest) obtained through a private placement (including the purchase or sale of an interest in a so-called "hedge fund") unless such transaction has been pre-cleared by the AIM Trimark Compliance department following a determination that the proposed transaction does not (i) present any actual or potential conflict of interest, (ii) that the issuer is a "private issuer" under securities legislation and (iii) the Employee has no reason to believe that the issuer or a related subsidiary company (whether or not such securities are of the same class as the securities held by such Employee) will make a public offering of its securities within the next twelve months. The AIM Trimark Compliance department will also review the request with the Chief Investment Officer before granting pre-clearance. The AIM Trimark Compliance department will maintain a record of the approval and the rationale supporting the purchase of the Private Placement. If pre-clearance is provided, the security will then be added to the restricted list. Further, Employees who have been authorized to acquire securities in a private placement must disclose such investment when he/she plays a part in any client account's subsequent consideration of an investment in the issuer. In such circumstances, the client account's decision to purchase securities of the issuer is subject to an independent review by investment personnel with no personal interest in the issuer.

6.6 INVESTMENT CLUBS

An Employee is prohibited from participating in an investment club unless such participation has been approved by the AIM Trimark Compliance department following a determination that the following conditions have been satisfied:

- The Employee's participation does not create any actual or potential conflict of interest.

- The Employee does not control investment decision-making for the investment club.

- The Employee has made satisfactory arrangements to ensure that duplicate trade confirmations of investment club activity and quarterly statements of investment club holdings are provided to the AIM Trimark Compliance department by brokers acting on behalf of the investment club.

If participation in an investment club has been approved, all future trades will be subject to pre-clearance.

6.7 TRADING IN AMVESCAP

Employees are prohibited from trading in AMVESCAP during the "Close Periods". Details of the "Close Periods" are circulated to all employees by way of the internal e-


mail system and can also be found via the attached link:
http://atlas.amvescap.com/ags/amv_groupservices/sec_closed.html

A "Close Period" is defined by the rules as the period of 60 days prior to the announcement of the year end results and the period of 30 days prior to the announcement of the interim and quarterly results. The close period may be shorter depending on when the results are announced but cannot start until the end of the relevant reporting period.

Short term trading (i.e. buying and selling within a 60 day period) in AMVESCAP, where the intention is to make a quick profit, is prohibited.

7. REPORTING REQUIREMENTS

7.1 INITIAL REPORTS

Within 10 days of becoming an Employee, each Employee, using the Star Compliance system, must submit a statement containing the following information: (i) a complete list of all of his or her Covered Accounts (including the name of the broker, dealer or bank with which the Employee maintained the Account); (ii) a list of each Reportable Security (whether held through a Covered Account, in certificate form, or otherwise) in which he or she has direct or indirect beneficial ownership (e.g., that he or she owns); and (iii) the date the Employee submits the report. The statement must be current as of a date no more than 45 days prior to the date of becoming an Employee.

7.2 REPORTS OF TRADE CONFIRMATIONS AND QUARTERLY REPORTS

Within 10 calendar days of settlement of each personal securities transaction involving a Reportable Security, whether the transactions had to be pre-cleared or not, the Employee engaging in the transaction must file or cause to be filed with the AIM Trimark Compliance department a duplicate copy of the broker/dealer confirmation, or such other confirmations as are available, for such transaction. In addition, except to the extent that such report would duplicate information contained in such confirmations, within 30 calendar days after the end of each calendar quarter, the Employee must submit a statement: (i) with respect to each personal securities transaction during the quarter in a Reportable Security in which the Employee had any direct or indirect beneficial ownership; (ii) with respect to any Covered Account established during the quarter, the name of the broker, dealer or bank with which the account was established, the date the account was established, and (iii) the date that the statement is submitted by the Employee.

Notwithstanding the reporting requirements set forth in the previous paragraph, transactions effected pursuant to an automatic investment plan need not be reported in the quarterly statement (nor in trade confirmations in lieu of the quarterly statement). An "automatic investment plan" means any program in which regular periodic purchases (or withdrawals) are made automatically in (or from) investment accounts in accordance with a predetermined schedule and allocation. An automatic investment plan includes a dividend reinvestment plan.


7.3 ANNUAL REPORTS

By January 30 of each year, each Employee must file with the AIM Trimark Compliance department an annual account statement as of December 31 of each year, (i) all Covered Accounts of such Employee (including the name of the broker, dealer or bank with which the Employee maintained the account) (ii) each Reportable Security (whether held through a Covered Account, in certificate form, or otherwise) in which he or she has direct or indirect beneficial ownership; and (iii) the date the Employee submits the account statements.

Employees are encouraged to request their broker or dealer to automatically send the AIM Trimark Compliance department copies of trade confirmations and monthly account statements. By doing so, the Employee does not have to make arrangements every time to meet the ongoing quarterly and annual reporting requirements.

The AIM Trimark Compliance department will review all reports submitted and report any irregularity to the Code of Ethics Committee.

7.4 REPORTABLE SECURITY

For purposes of this Policy, the term "Reportable Security" means any security except the following:

- Unit investment trusts (i.e., variable insurance contracts funded by insurance company separate accounts organized as unit investment trusts) invested exclusively in open-end U.S. mutual funds that are not managed or distributed by AIM Trimark or any AMVESCAP Company.

- Open-end U.S. mutual funds that are not managed or distributed by AIM Trimark or any AMVESCAP Company.

- Open-end Canadian mutual funds that are not managed or distributed by AIM Trimark.

- Securities issued or guaranteed by (i.e., securities that are the direct obligations of) the government of the United States.

- Money market funds.

- Money market instruments. a money market instrument is a debt instrument that has a maturity at issuance of less than 366 days and
(i) is rated in one of the two highest ratings categories by a statistical rating organization that is nationally recognized in the United States or a rating organization not affiliated with AIM Trimark and of comparable status in Canada or (ii) if not rated, is determined by AIM Trimark in good faith to be of equivalent quality such that it presents a comparable (or better) degree of safety of principal. For example, a short-term debt instrument with a rating of AA or AAA by Moody's Investors Service or AA or AAA


by Standard & Poor's Corporation meets this definition of money market instrument. Typical examples of money market instruments include bankers' acceptances, bank certificates of deposit, commercial paper and repurchase agreements.

8. INDEPENDENT DIRECTORS

Except as otherwise provided in the special procedures for independent directors of US Funds, personal securities transactions of independent directors of AIM Trimark or of AIM Trimark's corporate funds and members of the Fund's Advisory Boards are not subject to either the pre-clearance or reporting requirements set forth in this Policy, except with respect to personal securities transactions in the shares of AMVESCAP or shares of any closed-end investment company or investment trust served by such independent director in a director or trustee capacity.

8.1 FOR PURPOSES OF THIS EXCEPTION THE TERM "INDEPENDENT DIRECTOR" MEANS

a) any director of AIM Trimark's corporate funds or members of the AIM Trimark Fund Advisory Board

i) who is neither an officer nor employee of AMVESCAP or of any AMVESCAP Company, or

ii) who is not otherwise "connected with" AMVESCAP or any AMVESCAP Company within the meaning of the London Stock Exchange Yellow Book; and

b) any director of AIM Trimark who

i) is neither an officer nor employee of AMVESCAP or of any AMVESCAP Company,

ii) is not otherwise "connected with" AMVESCAP or any AMVESCAP Company within the meaning of the London Stock Exchange Yellow Book,

iii) is not an interested person of a US Fund under Section 2(a)(19) of the Investment Company Act (1940) and would otherwise be required to submit a pre-clearance request or make a report solely by reason of being an AIM director and

iv) does not regularly obtain information concerning the investment recommendations or decisions made by AIM Trimark on behalf of the US Funds.

8.2 SPECIAL PROCEDURES FOR INDEPENDENT DIRECTORS OF US FUNDS

While an "independent director" of AIM Trimark is not deemed to be an "Employee" and consequently is not subject to most of the procedures specified in this Policy with respect


to securities transactions, independent directors of AIM Trimark are subject to all of the following provisions. For purposes of this Policy, a "US Fund" is an investment fund whose activities are governed by the laws of the United States.

- An independent director is expected to adhere to the insider trading requirements.

- An independent director is expected to avoid engaging in any of the following actions:

- Employ any device, scheme or artifice to defraud a US Fund.

- Make any untrue statement of a material fact to directors, officers or agents of a US Fund or with respect to the securities or investment operations of a US Fund, or omit to state a material fact necessary in order to make such statements in light of the circumstances under which they were made, not misleading.

- Engage in any act, practice or course of business that operates or would operate as a fraud or deceit on a US Fund.

- Engage in any manipulative practice with respect to a US Fund.

- Prior to engaging in a personal securities transaction in a security (other than in a security excluded from pre-clearance), if an independent director knows, or in the ordinary course of fulfilling his or her official duties as an independent director to AIM Trimark, should have known, that during the 15-day period immediately before the date of his or her prospective transaction in the security, (i) a US Fund purchased or sold the security or (ii) a US Fund or its adviser or sub-adviser considered purchasing or selling the security, he or she is required to do the following: not purchase or sell such security until the day next following the completion by the Fund of its transaction, unless the director has submitted a pre-clearance request and the AIM Trimark Compliance department reasonably determines that, in view of the nature of the security and the market for the security, the director's transaction is not likely to affect the price paid for or received by the Fund. Absent such a finding, if such a transaction nonetheless is placed, the transaction is considered prohibited and any profits related thereto must be disgorged (to the Fund or an appropriate charity).

- If an independent director knows, or in the ordinary course of fulfilling his or her official duties as an independent director to AIM Trimark should have known, that during the 15-day period immediately before or after the date of the director's transaction in a security (other than those excluded from reporting), (i) a US Fund purchased or sold the security or (ii) a US Fund or its adviser or sub-adviser considered purchasing or selling the


security, he or she is required, whether or not he or she has pre-cleared the transaction, to follow the reporting requirements as if he or she were an Employee.

9. CERTIFICATION OF COMPLIANCE

By signing off on the AMVESCAP Code of Conduct and the AIM Trimark Addendum to the Code on an annual basis, Employees are also confirming adherence to this Policy.

INVESCO LTD.

CODE OF CONDUCT

INTRODUCTION

Our company's Core Purpose and Mission are a logical beginning point for our Code of Conduct:

Invesco is committed to "Helping People Worldwide Build Their Financial Security". That Core Purpose underlies our Mission, which is to deliver superior investment performance worldwide. Over the years, Invesco has developed a set of values that will continue to help us achieve our Core Purpose and Mission. Our values include:

- Working with integrity

- Respecting our employees and clients

- Empowering people

This Code of Conduct ("Code of Conduct" or "Code") has been created to assist us in accomplishing our Core Purpose and Mission. It contains a number of policies and standards which, when taken together, are designed to help define the essence of the conduct of an Invesco representative. These policies and standards are also intended to provide guidance to Invesco personnel in fulfilling their obligations to comply with applicable laws, rules and regulations. This Code of Conduct applies to all officers and other employees of Invesco and its subsidiaries (collectively, "Covered Persons"). These standards are neither exclusive nor complete. Additional company policies and rules can be found in the company's Intranet site, and others may be published to company personnel from time to time. Covered Persons are required to comply with all applicable laws, rules and regulations, whether or not specifically addressed in these policies. For additional guidance, or if you have questions regarding the existence, interpretation or application of any law, rule or regulation, please contact your supervisor, the General Counsel of your business unit or division, or the Invesco General Counsel.

Page 1 of 23

Our culture is based upon a set of shared values and principles. These include working with integrity and commitment to our clients, colleagues and communities. In practice, this means that our clients' interests must always come first, that Covered Persons should treat each other with respect and consideration, and that Invesco should participate as a responsible corporate citizen in every community in which it operates. This commitment is a vital part of our achieving our principal responsibility as a publicly-held company:
producing a fair return on our shareholders' capital.

This Code of Conduct contains broad and general principles that supplement the specific policies, procedures and training within each business unit of Invesco.

YOUR RESPONSIBLITIES

One person's misconduct can damage our entire company's hard-earned reputation and compromise the public's trust in the company. Every Covered Person should therefore become familiar with this Code and abide strictly by its provisions. In brief:

- It is your responsibility at all times to comply with the law and behave in an ethical manner.

- This Code cannot anticipate every possible situation or cover every topic in detail. The company has established special policies to address specific subjects and will update this Code and those specific policies from time-to-time. If you are unclear about a situation, stop and ask for guidance before taking action.

- Failure to obey laws and regulations violates this Code and may expose both you and the company to criminal or civil sanctions. Any violation of this Code or other company policies may result in disciplinary action, up to and including termination of employment. The company may also seek civil remedies from you and even refer criminal misconduct to law enforcement agencies.

- You are responsible for reporting possible violations of this Code to the company (see below).

- If you have a question about a topic covered in this Code or a concern regarding any conduct, please speak with your supervisor or with an appropriate member of the Legal & Compliance Department.

- If you are aware of a violation and are uncomfortable speaking with any of these people or wish to remain anonymous, you may call the toll-free Invesco Compliance Reporting Line (the "Compliance Reporting Line"). If you are calling from a U.S. or Canadian location dial 1-866-297-3627. For calls from all other locations, dial an international operator and request a collect call to 1-704-943-1136. When asked for your name use "Invesco." (See further details below.)

Page 2 of 23

- If you are an attorney or an executive officer of the company, you may have additional reporting or other obligations under specific rules applicable to you, such as the POLICY FOR REPORTING BY ATTORNEYS EMPLOYED BY INVESCO LTD. AND ITS SUBSIDIARIES, and you should also comply with such rules.

STATEMENT OF GENERAL PRINCIPLES

Invesco with its subsidiaries and various divisions operates in a highly-regulated and complex environment. There are numerous layers of overlapping, and occasionally conflicting, laws, customs and local practices. This Code of Conduct was designed to provide all of us who are part of the Invesco group with a clear statement of our firm's ethical and cultural standards.

We operate in major countries and securities markets throughout the world. Generally, we serve our clients as fiduciaries.

Fiduciary businesses are generally held to a higher standard of conduct than other businesses, and as such there are special obligations that apply. The following key duties and principles govern our conduct as fiduciaries:

- Best interests of clients - As fiduciaries, we have a duty to act with reasonable care, skill and caution in the best interests of our clients, and to avoid conflicts of interest.

- Global fiduciary standards - Invesco seeks to maintain the same high fiduciary standards throughout the world, even though those standards may not be legally required, or even recognized, in some countries.

- Compliance with applicable laws, rules and regulations - We have a duty to comply with the laws, rules and regulations of the jurisdictions in which we operate, and to comply with the terms of our agreements with our clients.

- Client confidentiality - We must maintain the confidentiality of information relating to the client, and comply with the data protection requirements imposed by many jurisdictions.

- Information - Clients must be provided with timely and accurate information regarding their accounts.

- Segregation and protection of assets - Processes must be established for the proper maintenance, control and protection of client assets. Fiduciary assets must be segregated from Invesco assets and property.

Page 3 of 23

- Delegation of duties - Fiduciary duties should be delegated only when the client consents and where permitted by applicable law. Reasonable care, skill and caution must be exercised in the selection of agents and review of their performance.

- Client guidelines - Invesco is responsible for making investment decisions on behalf of clients that are consistent with the prospectus, contract, or other controlling document relating to the client's account.

- Relations with regulators - We seek relationships with regulators that are open and responsive in nature.

1. Compliance with Laws, Rules and Regulations

Invesco strives to ensure that all activity by or on behalf of Invesco is in compliance with applicable laws, rules and regulations ("applicable laws"). Many of these applicable laws are specifically described in this Code of Conduct and in other Invesco and business unit policies and procedures. In the conduct of our business, all Covered Persons are required to comply with all applicable laws.

2. Fair and Honest Dealing

Covered Persons shall deal fairly and honestly with Invesco's shareholders, customers, suppliers, competitors and employees. Covered Persons shall behave in an ethical manner and shall not take unfair advantage of anyone through manipulation, concealment, abuse of privileged information, misrepresentation of material facts, or any other unfair dealing practice.

3. Conflicts of Interest

Invesco and its Covered Persons must adhere to the highest standards of honest and ethical conduct. These include, but are not limited to, sensitivity to the existence of a conflict of interest or the appearance of a conflict of interest. Conflicts of interest can arise in many ways, and we must all be sensitive to those situations in which they are most likely to be present. A conflict of interest exists when a Covered Person's personal interest interferes, or appears to interfere, in any way with the interests of Invesco or its clients, or when a Covered Person otherwise takes actions or has interests that may make it difficult to perform his or her company work objectively and effectively. For example, a conflict of interest would arise if a Covered Person, or a member of his or her family, receives improper personal benefits as a result of his or her position with Invesco.

All Covered Persons owe a duty of undivided and unqualified loyalty to Invesco and may not use their positions improperly to profit personally or to assist others in profiting at the expense of the company. All Covered Persons are therefore expected and

Page 4 of 23

required to regulate their activities so as to avoid conflicts of interest. In addition, Covered Persons shall promptly communicate to the applicable member of the Legal & Compliance Department any material transaction or relationship that reasonably could be expected to give rise to a conflict of interest so that the company and the Covered Person may take steps to minimize the conflict.

Covered Persons shall not take for personal use (or for use by a family member) any business opportunity learned of during the course of serving Invesco, using Invesco property or as a result of such individual's position with Invesco. To the extent that an employee or officer learns of a business opportunity that is within Invesco's existing or proposed lines of business, the employee or officer should inform his or her supervisor, the divisional or business unit General Counsel, or the Board of Directors, as appropriate, of the business opportunity and refrain from personally pursuing the matter until such time as Invesco decides to forego the business opportunity. At no time may any employee or officer utilize any Invesco property, information or position to generate personal gain or engage or participate in any business that directly competes with Invesco.

While not all-inclusive, the following examples of outside financial interests will serve to illustrate some of the types of activities that might cause conflicts of interest:

- Ownership or other interest in or employment by any outside concern which does business with Invesco. This does not apply to stock or other investments in a publicly-held company, provided that the stock and other investments do not, in the aggregate, exceed 5% of the outstanding ownership interests of such company. Invesco may, following a review of the relevant facts, permit ownership interests which exceed these amounts if management or the Board of Directors, as appropriate, concludes that such ownership interests will not adversely affect Invesco's business interests or the judgment of the affected Covered Person.

- Conducting business, not on behalf of Invesco, with any Invesco vendor, supplier, contractor, agency, or any of their directors, officers or employees.

- Representation of Invesco by a Covered Person in any transaction in which he or she, or a family member, has a substantial personal interest.

- Disclosure or use of confidential, special or inside information of or about Invesco, particularly for personal profit or advantage of the Covered Person or a family member of such person.

- Competition with Invesco by a Covered Person, directly or indirectly, in the purchase, sale or ownership of property or services or business investment opportunities.

Page 5 of 23

As described in more detail in Sections 4, 5 and 6 below, acting as an officer or director of an outside organization, personal share dealing, and the use of material non-public information represent additional areas where conflicts can arise and are of particular sensitivity.

In addition to conflicts of interest between the company and its Covered Persons, conflicts of interest may arise between the company and its clients, including investment funds. Where a Covered Person is trading in securities owned by client accounts, or where a portfolio management team for a hedge fund also manages mutual funds that invest in the same securities, are each examples of situations that may give rise to real or apparent conflicts of interest. All Covered Persons must follow the procedures in place within their respective divisions and business units and must also be sensitive to the types of situations that can give rise to such conflicts or apparent conflicts.

4. Outside Activities and Compensation

No Covered Person shall perform work or render services for any competitor of Invesco or for any organization with which Invesco does business or which seeks to do business with Invesco, outside of the normal course of his or her employment with Invesco, without the prior written approval of the company. Nor shall any such person be a director, officer, or consultant of such an organization, or permit his or her name to be used in any fashion that would tend to indicate a business connection with such organization, without such approval. Outside organizations can include public or private corporations, partnerships, charitable foundations and other not-for-profit institutions. With the above approval, Covered Persons may receive compensation for such activities.

Service with organizations outside of Invesco can, however, raise serious regulatory issues, including conflicts of interest and access to material non-public information.

As an outside board member or officer, a Covered Person may come into possession of material non-public information about the outside company or other public companies. It is critical that a proper information barrier be in place between Invesco and the outside organization, and that the Covered Person does not communicate such information to other Covered Persons in violation of the information barrier.

Similarly, Invesco may have a business relationship with the outside organization or may seek a relationship in the future. In those circumstances, the Covered Person must not be involved in any way in the business relationship between Invesco and the outside organization.

Invesco retains the right to prohibit membership by Covered Persons on any board of directors/trustees or as an officer of an outside organization where such membership might conflict with the best interests of the company. Approval will be granted on a

Page 6 of 23

case-by-case basis, subject to proper resolution of potential conflicts of interest. Outside activities will be approved only if these issues can be satisfactorily resolved.

5. Personal Share Dealing

Purchasing and selling securities in a Covered Person's own account, or accounts over which the Covered Person has access or control, can give rise to potential conflicts of interest. As fiduciaries, we are held to the highest standards of conduct. Improperly gaining advance knowledge of portfolio transactions, or conducting securities transactions based upon information obtained at Invesco, can be a violation of those standards.

All personal securities transactions must be pre-cleared unless an exemption is obtained. Generally, an exemption will be granted only for Covered Persons whose duties do not give them access to information regarding the sale or purchase of, or the recommendation to sell or purchase, securities in any portfolio. Transactions in certain retirement benefit plans, such as 401(k)s and Money Purchase Plans, and in specified categories of securities, are exempt from pre-clearance. Every Covered Person must also comply with the specific rules in effect in this area for the Covered Person's division or business unit.

Invesco also has policies that specifically cover personal transactions in the shares and American Depositary Shares of the company. All Covered Persons are obligated to follow those procedures whenever they conduct such transactions.

6. Information Barriers and Material Non-Public Information

In the conduct of our business, Covered Persons may come into possession of material non-public information. This information could concern an issuer, a client, a portfolio, the market for a particular security, or Invesco itself. The purchase or sale of Invesco's securities or the securities of other publicly-traded companies while aware of material nonpublic information about such company, or the disclosure of material nonpublic information to others who then trade in such company's securities, is prohibited by this Code of Conduct and by United States and other jurisdictions' securities laws. Invesco and its subsidiaries have adopted insider trading policies that apply to all Covered Persons. All Covered Persons should review the insider trading policies carefully and follow the policies and procedures described therein. The failure of a Covered Person to comply with the company's insider trading policy may subject him or her to company-imposed sanctions, up to and including termination for cause, whether or not the failure to comply results in a violation of law. You should seek the advice of the applicable divisional or business unit General Counsel on any questions regarding this subject and the company's insider trading policy. All Covered Persons are prohibited from using such information in ways that violate the law, including for personal gain. Non-public information must be kept confidential, which may include keeping it confidential from other Covered Persons.

Page 7 of 23

7. Anti-Bribery and Dealings with Governmental Officials

Special care must be taken when dealing with government customers. Activities that might be appropriate when working with private sector customers may be improper and even illegal when dealing with government employees, or when providing goods and services to another customer who, in turn, will deliver the company's product to a government end user. Many of the countries in which Invesco conducts its business prohibit the improper influencing of governmental officials or other persons by the payment of bribes, gifts, political contributions, lavish hospitality or by other means. Our policy requires adherence to those restrictions.

Do not directly or indirectly promise, offer or make payment in money or anything of value to anyone, including a government official, agent or employee of a government, political party, labor organization or business entity or a candidate of a political party, or their families, with the intent to induce favorable business treatment or to improperly affect business or government decisions. This policy prohibits actions intended either to influence a specific decision or merely to enhance future relationships. In general, all travel and entertainment that Covered Persons provide to governmental officials must be pre-approved within the appropriate business unit. If approved, a written confirmation that such expenses do not violate local law must be obtained from an appropriate third party (e.g., the business unit's legal counsel or the government official's supervisor).

Covered Persons shall comply with all laws, rules and regulations governing political campaign finance and lobbying activities and shall not engage in any conduct that is intended to avoid the application of such laws to activities undertaken on Invesco's behalf. In addition, appropriate executive officers shall monitor compliance with lobbyist registration and disclosure requirements by all individuals who act on behalf of Invesco.

These prohibitions extend to any consultants or agents we may retain on behalf of Invesco.

8. Anti-Discrimination and Harassment

Invesco is committed to providing a work environment that is free of discrimination and harassment. Such conduct, whether overt or subtle, is demeaning, may be illegal, and undermines the integrity of the employment relationship.

Sexual harassment can include unwelcome sexual advances, requests for sexual favors, pressure to engage in a sexual relationship as a condition of employment or promotion, or conduct which creates a hostile or offensive work environment.

Discrimination can take many forms including actions, words, jokes, or comments based upon an individual's race, citizenship, ethnicity, color, religion, sex, veteran status,

Page 8 of 23

national origin, age, disability, sexual orientation, marital status or other legally protected characteristic. Any Covered Person who engages in harassment or discrimination will be subject to disciplinary action, up to and including termination of employment.

9. Anti-Money Laundering

In the global marketplace, the attempted use of financial institutions and instruments to launder money is a significant problem that has resulted in the passage of strict laws in many countries. Money laundering is the attempt to disguise money derived from or intended to finance illegal activity including drug trafficking, terrorism, organized crime, fraud, and many other crimes. Money launderers go to great lengths to hide the sources of their funds. Among the most common stratagems are placing cash in legitimate financial institutions, layering between numerous financial institutions, and integrating the laundered proceeds back into the economy as apparently legitimate funds.

All Covered Persons must be vigilant in the fight against money laundering, and must not allow Invesco to be used for money laundering. Each business unit has developed an anti-money laundering program that is consistent with Invesco's group-wide policy. Each Covered Person must comply with the applicable program.

10. Antitrust

The laws of many countries are designed to protect consumers from illegal competitive actions such as price fixing and dividing markets. It is Invesco's policy and practice to compete based on the merits of our products and services. In order to further that policy, Covered Persons must not fix or control prices with competitors, divide up territories or markets, limit the production or sale of products, boycott certain suppliers or customers, unfairly control or restrict trade in any way, restrict a competitor's marketing practices, or disparage a competitor. Covered Persons must never discuss products, pricing or markets with competitors with the intent to fix prices or divide markets.

11. Data Privacy

Data privacy, as it relates both to our clients and our employees, has become a major political and legal issue in many jurisdictions in which we do business. A variety of laws in each of those jurisdictions governs the collection, storage, dissemination, transfer, use, access to and confidentiality of personal information and patient health information. These laws can work to limit transfers of such data across borders and even among affiliated entities in the Invesco group of companies. Invesco and its Covered Persons will comply with all provisions of these laws that relate to its business, including the privacy, security and electronic transmission of financial, health and other personal information. The company expects its Covered Persons to keep all such data

Page 9 of 23

confidential and to protect, use and disclose information in the conduct of our business only in compliance with these laws. The company will consider and may release personal information to third parties to comply with law or to protect the rights, property or safety of Invesco and its customers. . In accordance with Invesco policies, each business unit has developed required disclosures and data security procedures applicable to that business unit. All Covered Persons must comply with the applicable procedures.

With respect to Invesco Covered Persons, all salary, benefit, medical and other personal information relating to Covered Persons shall generally be treated as confidential. Personnel files, payroll information, disciplinary matters, and similar information are to be maintained in a manner designed to protect confidentiality in accordance with applicable laws. All Covered Persons shall exercise due care to prevent the release or sharing of such information beyond those persons who may need such information to fulfill their job functions. Notwithstanding the foregoing, all personnel information belongs solely to Invesco and may be reviewed or used by the company as needed to conduct its business.

12. Communications with the Media and Analysts

Invesco has a long-standing policy of co-operating with the news media and the financial community. This policy is intended to enhance respect for the company, provide accurate information, and achieve our business goals.

Invesco employs media relations professionals who are responsible for handling all contacts with the news media. Invesco's Communications and Corporate Affairs Department is responsible for formulating and directing our media relations policy worldwide. Other Invesco employees may not speak to or disseminate information to the news media unless such contact has been requested and arranged by or coordinated with an Invesco media relations professional in accordance with the company's media relations policy. Any contact from the news media should be referred promptly and without comment to an Invesco media relations professional. If you do not know the appropriate media relations professional for your unit, you can refer the contact to the Invesco Communications and Corporate Affairs Department.

Many countries have detailed rules with regard to the dissemination of information about public companies. In particular, a public company must have procedures for controlling the release of information that may have a material impact on its share price. The Chief Executive Officer and the Chief Financial Officer are responsible for Invesco's relationships with the financial community, including the release of price sensitive information. Other Invesco employees may not speak to or disseminate information regarding the company to the financial community (including analysts, investors, shareholders, Company lenders, and rating agencies) unless such contact has been requested and arranged by the Chief Executive Officer, the Chief Financial Officer or the Investor Relations Group within the Finance Department.

Page 10 of 23

13. Electronic Communications

The use of electronic mail, the Internet and other technology assets is an important part of our work at Invesco. Used improperly, this technology presents legal and business risks for the company and for individual employees. There are also important privacy issues associated with the use of technology, and related regulations are evolving.

In accordance with Invesco's Electronic Communications policies, all Covered Persons are required to use information technology for proper business purposes and in a manner that does not compromise the confidentiality of sensitive or proprietary information. All communications with the public, clients, prospects and fellow employees must be conducted with dignity, integrity, and competence and in an ethical and professional manner.

We must not use information technology to: transmit or store materials which are obscene, pornographic, or otherwise offensive; engage in criminal activity; obtain unauthorized access to data or files; commit copyright violations; install personal software without permission; or make Internet statements, without permission, that suggest that the user is speaking on behalf of Invesco or its affiliates.

14. Gifts and Relationships with Customers and Suppliers

Invesco seeks to do business with clients and suppliers on a fair and equitable basis. We may not accept gifts of other than nominal value, or lavish entertainment, or other valuable benefits or special favors from customers or suppliers. We must observe any limits imposed by our business unit's policies, local laws, or regulations with respect to the acceptance of gifts or gratuities.

15. International Issues

If you conduct business for Invesco outside of the U.S., in addition to being familiar with the local laws of the other countries involved, be sure you are familiar with the following U.S. laws and regulations. Violations of these laws can result in substantial fines, imprisonment and severe restrictions on the company's ability to do business.

FOREIGN CORRUPT PRACTICES ACT

The United States Foreign Corrupt Practices Act (FCPA) and similar laws in many other countries have a variety of provisions that regulate business in other countries and with foreign citizens. In essence, these laws make it a crime to promise or give anything of value to a foreign official or political party in order to obtain or keep business or obtain any improper advantage. It is also illegal to make payments to agents, sales representatives or other third parties if you have reason to believe your gift will be used illegally. Seek advice from the appropriate member of the Legal & Compliance

Page 11 of 23

Department for interpretation of the FCPA or similar laws if you are involved in any business dealings that involve foreign countries.

ANTI-BOYCOTT LAWS

From time to time, various countries may impose restrictions upon the ability of businesses in their jurisdiction to engage in commerce with designated individuals, countries or companies. These laws are commonly referred to as boycotts or trade embargoes. It may be against the law to cooperate in any boycotts between foreign countries not sanctioned by the laws of the place where your office is located. All requests for boycott support or boycott-related information must be reported to your supervisor and the member of the Legal & Compliance Department with responsibility for your office.

Similarly, many countries contribute the names of criminal or terrorist organizations or individuals to a common database and require financial institutions to screen customer lists against the database as part of their "Know Your Customer" obligations. We must be aware of, and where appropriate, adhere to any such restrictions.

EMBARGO SANCTIONS

The United States Treasury Department's Office of Foreign Assets Control prohibits U.S. companies and their foreign subsidiaries from doing business with certain countries and agencies and certain individuals. The laws of other countries may have similar types of prohibitions. The regulations vary depending on the country and the type of transaction and often change as countries' foreign policies change. If you are aware of any sensitive political issues with a country in which Invesco is doing or considering doing business, seek advice from the appropriate member of the Legal & Compliance Department.

16. Political Activities and Lobbying

Covered Persons are encouraged to vote in elections for which they are eligible, and to make contributions supporting candidates or parties of their choice. Covered Persons are also encouraged to express their views on government, legislation and other matters of local or national interest.

Many jurisdictions have imposed severe and complex restrictions on the ability of individuals and companies to make political contributions. You should assume that Invesco and its Covered Persons are generally prohibited from certain types of political activities, and you must be familiar with the rules in effect for your business unit. No Covered Person may, under any circumstances, use company funds to make political contributions without the prior written approval of a member of the Legal & Compliance Department, nor may you represent your personal political views as being those of the company.

Page 12 of 23

17. Retention of Books and Records

Invesco corporate records are important assets. Corporate records include essentially everything you produce as a Covered Person, regardless of its format. A corporate record may be in the form of paper, computer tapes, microfilm, e-mail, or voice mail. It may be something as obvious as a memorandum or a contract or something not as obvious, such as a desk calendar, an appointment book, or an expense record.

Invesco is required by law to maintain certain types of corporate records, usually for a specified period of time. Failure to retain such documents for such minimum periods could subject Invesco to penalties and fines, cause the loss of rights, obstruct justice, place Invesco in contempt of court, or place Invesco at a serious disadvantage in litigation. However, storage of voluminous records over time is costly. Therefore, Invesco has established controls to assure retention for required periods and timely destruction of retrievable records, such as paper copies and records on computers, electronic systems, microfiche, and microfilm. Even if a document is retained for the legally required period, liability could still result if a document is destroyed before its scheduled destruction date.

Invesco and its affiliates are subject to the regulatory requirements of numerous countries and regulatory agencies. Virtually all of them have specific requirements concerning the creation, maintenance and storage of business records. Invesco expects all Covered Persons to become familiar with and fully comply with the records retention/destruction schedule for the departments and office locations for which they work. If you believe documents should be retained beyond the applicable retention period, consult with the Legal & Compliance Department.

18. Sales and Marketing Materials

Invesco is committed to building sustained, open, and honest relationships with our customers, and to complying with all relevant regulatory requirements. This requires that all marketing and sales-related materials be prepared under standards approved by the Legal & Compliance Department and, prior to use, reviewed and approved by the appropriate supervisor within a business unit. Covered materials include requests for proposals, client presentations, performance summaries, advertisements, and published market commentaries.

19. Substance Abuse

Invesco is committed to providing a safe and healthy work place for all employees. The use, possession, sale, transfer, purchase, or being "under the influence" of drugs at any time while on company premises or on company business is prohibited. The term "drug" includes alcoholic beverages (other than in connection with entertainment

Page 13 of 23

events, or in other appropriate settings), prescriptions not authorized by your doctor, inhalants, marijuana, cocaine, heroin and other illegal substances.

20. Confidential Information

Confidential information includes all non-public information that might be of use to competitors, or harmful to the company or its customers, if disclosed. All information (in any form, including electronic information) that is created or used in support of company business activities is the property of Invesco. This company information is a valuable asset and Covered Persons are expected to protect it from unauthorized disclosure. This includes Invesco customer, supplier, business partner and employee data. United Kingdom, United States (federal and state) and other jurisdictions' laws may restrict the use of such information and impose penalties for impermissible use or disclosure.

Covered Persons must maintain the confidentiality of information entrusted to them by the company or its customers, vendors or consultants except when disclosure is properly authorized by the company or legally mandated. Covered Persons shall take all reasonable efforts to safeguard such confidential information that is in their possession against inadvertent disclosure and shall comply with any non-disclosure obligations imposed on Invesco in its agreements with third parties.

Information pertaining to Invesco's competitive position or business strategies, and information relating to negotiations with Covered Persons or third parties, should be protected and shared only with Covered Persons having a need to know such information in order to perform their job responsibilities.

21. Protection and Proper Use of Company Assets

All Covered Persons shall strive to preserve and protect the company's assets and resources and to promote their efficient use. The standards set forth below are intended to guide Covered Persons by articulating Invesco's expectations as they relate to activities or behaviors that may affect the company's assets.

Personal Use of Corporate Assets

Theft, carelessness and waste have a direct impact on Invesco's profitability. Covered Persons are not to convert assets of the company to personal use. Company property should be used for the company's legitimate business purposes and the business of the company shall be conducted in a manner designed to further Invesco's interest rather than the personal interest of an individual Covered Person. Covered Persons are prohibited from the unauthorized use or taking of Invesco's equipment, supplies, materials or services. Prior to engaging in any activity on company time which will result in remuneration to the Covered Person or the use of Invesco's equipment, supplies, materials or services for personal or non-work related purposes, officers and

Page 14 of 23

other Covered Persons shall obtain the approval of the supervisor of the appropriate business unit.

Use of Company Software

Covered Persons use software programs for word processing, spreadsheets, data management, and many other applications. Software products purchased by the company are covered by some form of licensing agreement that describes the terms, conditions and allowed uses. It is the company's policy to respect copyright laws and observe the terms and conditions of any license agreements. Copyright laws in the United States and other countries impose civil and criminal penalties for illegal reproductions and use of licensed software. You must be aware of the restrictions on the use of software and abide by those restrictions. Invesco business equipment may not be used to reproduce commercial software. In addition, you may not use personal software on company equipment without prior written approval.

Computer Resources/E-mail

The company's computer resources, which include the electronic mail system, belong to Invesco and not to the Covered Person. They are not intended to be used for amusement, solicitation, or other non-business purposes. While it is recognized that Covered Persons will occasionally use the system for personal communications, it is expected that such uses will be kept to a minimum and that Covered Persons will be responsible and professional in their use of e-mail. The use of the computer systems to make or forward derogatory or offensive remarks about other people or groups is prohibited. E-mail messages should be treated as any other written business communication.

22. Invesco Intellectual Property

Employees and officers must carefully maintain and manage the intellectual property rights of Invesco, including patents, trademarks, copyrights and trade secrets, to preserve and protect their value. Information, ideas and intellectual property assets of Invesco are important to the company's success.

Invesco's name, logo, trademarks, inventions, processes and innovations are intellectual property assets and their protection is vital to the success of the company's business. The company's and any of its subsidiaries' names, logos and other trademarks and service marks are to be used only for authorized company business and never in connection with personal or other activities unless appropriately approved and in accordance with company policy. In addition, our Covered Persons must respect the intellectual property rights of third parties. Violation of these rights can subject both you and the company to substantial liability, including criminal penalties.

Page 15 of 23

Any work product produced in the course of performing your job shall be deemed to be a "work made for hire" and shall belong to Invesco and is to be used only for the benefit of Invesco. This includes such items as marketing plans, product development plans, computer programs, software, hardware and similar materials. You must share any innovations or inventions you create with your supervisor so that the company can take steps to protect these valuable assets.

23. Integrity and Accuracy of Financial Records

The preparation and maintenance of accurate books, records and accounts is required by law and essential to the proper discharge of financial, legal and reporting obligations. All Covered Persons are prohibited from directly or indirectly falsifying or causing to be false or misleading any financial or accounting book, record or account. In addition, all financial data must be completely and accurately recorded in compliance with applicable law and Invesco's accounting policies and procedures. A Covered Person may violate this section by acting or by failing to act when he or she becomes aware of a violation or potential violation of this section.

24. Disclosure in Reports and Documents.

Filings and Public Materials. As a public company, it is important that the company's filings with UK authorities, the United States Securities and Exchange Commission (the "SEC") and other U.S. federal, state, domestic and international regulatory agencies are full, fair, accurate, timely and understandable. The company also makes many other filings with the SEC and other UK, U.S. and international regulatory agencies on behalf of the funds that its subsidiaries and affiliates manage. Further, the company prepares mutual fund account statements, client investment performance information, prospectuses and advertising materials that are sent out to its mutual fund shareholders and clients.

Disclosure and Reporting Policy. The company's policy is to comply with all applicable disclosure, financial reporting and accounting regulations applicable to the company. The company maintains the highest commitment to its disclosure and reporting requirements, and expects and requires all Covered Persons to record information accurately and truthfully in the books and records of the company.

Information for Filings. Depending on his or her position with the company, a Covered Person may be called upon to provide necessary information to assure that the company's public reports and regulatory filings are full, fair, accurate, timely and understandable. The company expects all Covered Persons to be diligent in providing accurate information to the inquiries that are made related to the company's public disclosure requirements.

Disclosure Controls and Procedures and Internal Control Over Financial Reporting. Covered Persons are required to cooperate and comply with the company's disclosure

Page 16 of 23

controls and procedures and internal controls over financial reporting so that the company's reports and documents filed with the UK authorities, the SEC and other U.S. federal, state, domestic and international regulatory agencies comply in all material respects with applicable laws, and rules and regulations, and provide full, fair, accurate, timely and understandable disclosure.

25. Improper Influence on the Conduct of Audits

Every Covered Person must deal fairly and honestly with outside accountants performing audits, reviews or examinations of Invesco's and its subsidiaries' financial statements. To that end, no Covered Person of Invesco may make or cause to be made a materially false or misleading statement (or omit facts necessary to make the statements made not misleading) in connection with an audit, review or examination of financial statements by independent accountants or the preparation of any document or report required to be filed with a governmental or regulatory authority. Covered Persons of Invesco also are prohibited from coercing, manipulating, misleading or fraudulently inducing any independent public or certified public accountant engaged in the performance or review of financial statements that are required to be filed with a governmental or regulatory authority if he or she knows or should have known that his or her actions could result in making those financial statements materially misleading.

26. Standards for Invesco's Financial Officers

Invesco's Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer (the "Financial Officers") are required to take all reasonable steps to provide full, fair, accurate, timely and understandable disclosures in the reports and documents that Invesco files with or submits to the SEC and other regulatory bodies and in other public communications made by Invesco. In the event that a Financial Officer learns that any such report, document or communication does not meet this standard and such deviation is material, then the Financial Officers are required to review and investigate such deviation, advise the Board of Directors or the Audit Committee of the Board of Directors regarding the deviation and, where necessary, revise the relevant report, document or communication.

Although a particular accounting treatment for one or more of Invesco's operations may be permitted under applicable accounting standards, the Financial Officers may not authorize or permit the use of such an accounting treatment if the effect is to distort or conceal Invesco's true financial condition. The accounting standards and treatments utilized by Invesco must, in all instances, be determined on an objective and uniform basis and without reference to a single transaction or series of transactions and their impact on Invesco's financial results for a particular time period. Any new or novel accounting treatment or standard that is to be utilized in the preparation of Invesco's financial statements must be discussed with Invesco's Audit Committee and its independent auditors.

27. Policy and Procedures on Reporting Potential Material Violations

Invesco's Audit Committee has adopted the following statement of policy with respect to the reporting by employees of potential material violations of this Code of Conduct, laws or regulations and our related non-retaliation policy:

"Invesco strives to ensure that all activity by or on behalf of Invesco is in compliance with applicable laws, rules and regulations. Invesco and its employees must adhere to the highest standards of honest and ethical conduct. Employees of Invesco and its subsidiaries are affirmatively required to report possible violations of the Invesco Code of Conduct, laws or regulations promptly to their manager, a Human Resources Director at the employee's site, the employee's Legal and Compliance Department representative, or via the 24-hour toll-free, anonymous Invesco Compliance Reporting Line.

Invesco will not permit retribution, harassment, or intimidation of any employee who in good faith reports a possible violation. Specifically, Invesco policy prevents any employee from being subject to disciplinary or retaliatory action by Invesco or any of its employees or agents as a result of the employee's good faith:

- Disclosing information to a government or law enforcement agency, where the employee has reasonable cause to believe that the information discloses a violation or possible violation of federal or state law or regulation; or

- Providing information, causing information to be provided, filing, causing to be filed, testifying, participating in a proceeding filed or about to be filed, or otherwise assisting in an investigation or proceeding regarding any conduct that the employee reasonably believes involves a violation of: (1) any criminal law relating to securities fraud, mail fraud, bank fraud, or wire, radio, television or internet fraud; (2) any rule or regulation of the United States Securities and Exchange Commission or any other national, state or provincial securities regulatory authority; or any provision of applicable law relating to fraud against shareholders, where, with respect to investigations, such information or assistance is provided to or the investigation is being conducted by a national, state or provincial regulatory agency, a member of any parliamentary body, or a person at Invesco with supervisory or similar authority over the employee.

However, employees who file reports or provide evidence which they know to be false or without a reasonable belief in the truth and accuracy of such information will not be protected by the above policy statement and may be subject to disciplinary action, including termination of their employment."

If you are a Covered Person with complaints or concerns regarding:

(i) violations of this Code of Conduct or the rules mentioned herein;

Page 18 of 23

(ii) violations of laws or regulations generally involving Invesco; or

(iii) questionable accounting matters, internal accounting controls, auditing matters, breaches of fiduciary duty or violations of United States or foreign securities laws or rules (collectively "Accounting Matters"), including:

- fraud or deliberate error in the preparation, evaluation, review or audit of any financial statement of Invesco;

- fraud or deliberate error in the recording and maintaining of financial records of Invesco;

- deficiencies in or non-compliance with Invesco's internal accounting controls;

- misrepresentation or false statements to or by a senior officer or accountant regarding a matter contained in the financial records, financial reports or audit reports of Invesco;

- deviation from full and fair reporting of Invesco's financial condition; or

- fraudulent or criminal activities engaged in by officers, directors or employees of Invesco;

you may report your concerns in any of three ways:

YOU CAN SPEAK WITH YOUR SUPERVISOR. We encourage you to first contact your immediate supervisor, who is in turn responsible for informing Invesco's Compliance Reporting Line (described below) of any concerns raised.

YOU CAN SPEAK DIRECTLY WITH THE BUSINESS UNIT OR DIVISIONAL GENERAL COUNSEL. If you prefer not to discuss a concern with your own supervisor, you may instead contact the General Counsel of your business unit or division directly. You are also free to e-mail the business unit or divisional General Counsel at the appropriate e-mail address. Such person will then likewise be responsible for informing Invesco's Compliance Reporting Line (described below) of any concerns raised.

YOU CAN CALL OUR COMPLIANCE REPORTING LINE. You may also call the Invesco Compliance Reporting Line. If you are calling from a U.S. or Canadian location dial 1-866-297-3627. For calls from all other locations, dial an international operator and request a collect call to 1-704-943-1136. When asked for your name use "Invesco." You can use the Compliance Reporting Line to report possible violations or to check on the status of a previously filed report. You can also report to the Compliance Reporting Line if you believe that a report previously made to company management, your

Page 19 of 23

supervisor, other management personnel or the applicable business unit or divisional General Counsel has not been addressed.

The Compliance Reporting Line is administered by an outside vendor. The telephone operators for the Compliance Reporting Line have been trained to receive your call. The Compliance Reporting Line is available 24 hours a day, seven days a week. All calls will be answered by a live person. Calls are not recorded and are not able to be traced. You have the option to remain anonymous. If you remain anonymous, you will be given a numeric code so that you may call back and ask for follow up. You will be guided through the call and prompted by appropriate questions from the operator. You will be given a date on which you can call back and receive a follow up report. Once the call is completed, a report will be generated and sent to the appropriate departments within Invesco based on the subject matter of your call. You are urged to call back for follow up, because in the event more information is required, this will be an opportunity for you to provide those details.

If you report a possible violation, regardless of the method that you use to make the report, it is important that you provide as much detail as possible, including names, dates, times, locations and the specific conduct in question. Only with sufficient specific information can Invesco adequately investigate the reported action.

Your submission of information will be treated in a confidential manner to the extent reasonably possible. Please note, however, that if an investigation by Invesco of the activities you have reported takes place, it may be impossible for Invesco to maintain the confidentiality of the fact of the report or the information reported.

Complaints relating to Accounting Matters will be reviewed under Audit Committee direction and oversight by such persons as the Audit Committee determines to be appropriate. All other matters will be reviewed under the direction and oversight of the appropriate departments within Invesco, usually also including the Legal & Compliance Department. Prompt and appropriate corrective action will be taken when and as warranted in the judgment of the Audit Committee or other reviewing department.

28. Disclosure; Amendments

To the extent required by law, the company shall publicly (e.g., in its Annual Report on Form 20-F and/or on its website) disclose this Code of Conduct and its application to all of the company's Covered Persons.

Page 20 of 23

This Code may only be amended by Invesco's Board of Directors or a duly authorized committee thereof. To the extent required by law, amendments to the Code of Conduct shall be disclosed publicly. As set forth in Item 16B of the company's Annual Report on Form 20-F for 2005 filed with the SEC, the company has elected to disclose certain amendments to the Code that affect, and any waivers of the Code granted to, Financial Officers on the company's Web site in accordance with the requirements of Instruction 4 to Item 16B.

29. Waivers of the Code.

a. Waivers for Executive Officers. Any change in or waiver of this Code for executive officers (as defined in Rule 3b-7 under the Securities Exchange Act of 1934, "Executive Officers") of the company may be made only by the Board of Directors or a committee thereof in the manner described in Section 29(d) below, and any such waiver (including any implicit waiver) shall be promptly disclosed to shareholders as required by the corporate governance listing standards of the New York Stock Exchange and other applicable laws, rules and regulations.

b. Waivers for Other Covered Persons. Any requests for waivers of this Code for Covered Persons other than Executive Officers of the company may be made to the Legal and Compliance Department in the manner described in Section 29(e) below.

c. Definition of Waiver. For the purposes of the Code, the term "waiver" shall mean a material departure from a provision of the Code. An "implicit waiver" shall mean the failure of the company to take action within a reasonable period of time regarding a material departure from a provision of the Code that has been made known to an Executive Officer.

d. Manner for Requesting Executive Officer Waivers.

i. Request and Criteria. If an Executive Officer wishes to request a waiver of this Code, the Executive Officer may submit to the Global Compliance Director or the Legal and Compliance Department a written request for a waiver of the Code only if he/she can demonstrate that such a waiver:

A. is necessary to alleviate undue hardship or in view of unforeseen circumstances or is otherwise appropriate under all the relevant facts and circumstances;

B. will not be inconsistent with the purposes and objectives of the Code;

C. will not adversely affect the interests of clients of the company or the interests of the company; and

Page 21 of 23

D. will not result in a transaction or conduct that would violate provisions of applicable laws or regulations.

ii. Discretionary Waiver and Response. The Legal and Compliance Department will forward the waiver request to the Board of Directors or a committee thereof for consideration. Any decision to grant a waiver from the Code shall be at the sole and absolute discretion of the Board of Directors or committee thereof, as appropriate. The Company Secretary will advise the Legal and Compliance Department in writing of the Board of Director's decision regarding the waiver, including the grounds for granting or denying the waiver request. The Legal and Compliance Department shall promptly advise the Executive Officer in writing of the Board of Director's decision.

e. Manner for Requesting Other Covered Person Waivers.

i. Request and Criteria. If a Covered Person who is a non-Executive Officer wishes to request a waiver of this Code, such Covered Person may submit to the Legal and Compliance Department a written request for a waiver of the Code only if he/she can demonstrate that such a waiver would satisfy the same criteria set forth in Section 29(d).

ii. Discretionary Waiver and Response. The Legal and Compliance Department shall forward the waiver request to the General Counsel of the company for consideration. The decision to grant a waiver shall be at the sole and absolute discretion of the General Counsel of the company. The General Counsel will advise the Legal and Compliance Department in writing of his/her decision regarding the waiver, including the grounds for granting or denying the waiver request. The Legal and Compliance Department shall promptly advise the Covered Person in writing of the General Counsel's decision.

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

CONCLUSION

As Covered Persons, each of us is obligated to read and understand this Code of Conduct and our relevant business unit's policies and procedures. No code of conduct, however, can address every situation for which guidance may be necessary. If you are unclear about a situation, stop and ask for guidance before taking action. All Covered

Page 22 of 23

Persons are expected to abide by both the letter and spirit of this Code. Covered Persons are also expected to perform their work with honesty and integrity in any areas not specifically addressed by the Code. Invesco will investigate reported violations of the Code and, if violations are found, may take disciplinary action, if appropriate, against the individuals involved, and may make reports, if appropriate, to civil, criminal or regulatory authorities. Nothing in this Code restricts the company from taking any disciplinary action on any matters pertaining to the conduct of a Covered Person, whether or not expressly set forth in the Code. Any questions regarding the scope or interpretation of this Code should be referred to the appropriate Compliance or Legal officer.
