                              AIM BASIC VALUE FUND
                              --------------------

INVESTMENT OBJECTIVE AND STRATEGIES
- --------------------------------------------------------------------------------

The fund's investment objective is long-term growth of capital.

  The fund seeks to meet this objective by investing all of its investable
assets in the Value Portfolio (the portfolio), which in turn normally invests at
least 65% of its total assets in equity securities of U.S. issuers that have
market capitalizations of greater than $500 million and that the portfolio
managers believe to be undervalued in relation to long-term earning power or
other factors.

  The portfolio may also invest up to 35% of its total assets in equity
securities of U.S. issuers that have market capitalizations of less than $500
million and in investment-grade non-convertible debt securities, U.S. government
securities and high-quality money market instruments, all of which are issued by
U.S. issuers. The portfolio may also invest up to 25% of its total assets in
foreign securities.

  In selecting investments, the portfolio managers seek to identify those
companies whose prospects and growth potential are undervalued by investors and
that provide the potential for attractive returns. The portfolio managers
allocate investments among fixed-income securities based on their views as to
the best values then available in the marketplace. The portfolio managers
consider whether to sell a particular security when any of those factors
materially changes.

  In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, the portfolio may temporarily
hold all or a portion of its assets in cash, money market instruments, shares of
affiliated money market funds, or high-quality debt securities. As a result, the
fund or the portfolio may not achieve its investment objective.

  The portfolio may engage in active and frequent trading of portfolio
securities to achieve its investment objective. If the portfolio does trade in
this way, it may incur increased transaction costs and brokerage commissions,
both of which can lower the actual return on your investment. Active trading may
also increase short-term capital gains and losses, which may affect the taxes
you have to pay.

  If the fund's Board of Trustees determines that it is in the best interests of
the fund and its shareholders, the fund may redeem its investment in the
portfolio.

PRINCIPAL RISKS OF INVESTING IN THE FUND
- --------------------------------------------------------------------------------

There is a risk that you could lose all or a portion of your investment in the
fund. The value of your investment in the fund will go up and down with the
prices of the securities in which the portfolio invests. The prices of equity
securities change in response to many factors, including the historical and
prospective earnings of the issuer, the value of its assets, general economic
conditions, interest rates, investor perceptions, and market liquidity.

  Foreign securities have additional risks, including exchange rate changes,
political and economic upheaval, the relative lack of information about these
companies, relatively low market liquidity and the potential lack of strict
financial and accounting controls and standards.

  The fund currently participates in the initial public offering (IPO) market,
and a significant portion of the fund's returns currently are attributable to
its investment in IPOs, which have a magnified impact due to the fund's small
asset base. As the fund's assets grow, it is probable that the effect of the
fund's investment in IPOs on its total returns will decline, which may reduce
the fund's total returns.

  The value of your shares could be adversely affected if the computer systems
used by the portfolio's investment advisor and other service providers are
unable to distinguish the year 2000 from the year 1900.

  The portfolio's investment advisor and independent technology consultants are
working to avoid year 2000-related problems in its systems and to obtain
assurances that other service providers are taking similar steps. Year 2000
problems may also affect issuers in whose securities the portfolio invests.

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

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
The bar chart and table shown below provide an indication of the risks of
investing in the fund. The fund's past performance is not necessarily an
indication of its future performance. Total return information in the bar chart
and table below may be affected by special market factors, including the fund's
investments in initial public offerings, which may have a magnified impact on
the fund due to its small asset base. There is no guarantee that, as the fund's
assets grow, it will continue to experience substantially similar performance.

ANNUAL TOTAL RETURNS

The following bar chart shows changes in the performance of the fund's Class A

(1) If you buy $1,000,000 or more of Class A shares and redeem these shares
    within 18 months from the date of purchase, you may pay a 1% contingent
    deferred sales charge (CDSC) at the time of redemption.
(2) This fee table, and the expense example below, reflect the expenses of both
    the fund and the portfolio.
(3) The investment advisor has contractually agreed to limit net expenses.

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 example assumes that you invest $10,000 in the fund for the time periods
indicated and then redeem all of your shares at the end of those periods. The
example also assumes that your investment has a 5% return each year and that the
fund's gross operating expenses remain the same. To the extent fees are waived
or expenses are reimbursed, the expenses will be lower. Although your actual
returns and costs may be higher or lower, based on these assumptions your costs
would be:

FINANCIAL HIGHLIGHTS
- --------------------------------------------------------------------------------

The financial highlights table is intended to help you understand the fund's
financial performance. Certain information reflects financial results for a
single fund share.

  The total returns in the table represent the rate that an investor would have
earned (or lost) on an investment in the fund (assuming reinvestment of all
dividends and distributions).

  This information has been audited by PricewaterhouseCoopers LLP, whose report,
along with the fund's financial statements, is included in the fund's annual
report, which is available upon request.

   Total return information in this table may be affected by special market
factors, including the fund's investments in initial public offerings, which may
have a magnified impact on the fund due to its small asset base. There is no
guarantee that, as the fund's assets grow, it will continue to experience
substantially similar performance.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

In addition to the fund, A I M Advisors, Inc. serves as investment advisor to
many other mutual funds (the AIM Funds). The following information is about all
the AIM Funds.

CHOOSING A SHARE CLASS

Many of the AIM Funds have multiple classes of shares, each class representing
an interest in the same portfolio of investments. When choosing a share class,
you should consider the factors below:

<TABLE>
<CAPTION>
CLASS A                              CLASS B                              CLASS C

                                       years                                one year

- - Lower distribution and service     - 12b-1 fee of 1.00%                 - 12b-1 fee of 1.00%
  (12b-1) fee than Class B or
  Class C shares (See "Fee Table
  and Expense Example")

                                       reinvested dividends and
                                       distributions(1)

  long-term investors                  amounts less than $250,000           for short-term investors
</TABLE>

      (1) AIM Money Market Fund: Class B shares convert to AIM Cash Reserve
          Shares.

          AIM Global Trends Fund: If you held Class B shares on May 29,
          1998 and continue to hold them, those shares will convert to
          Class A shares of that fund seven years after your date of
          purchase. If you exchange those shares for Class B shares of
          another AIM Fund, the shares into which you exchanged will
          not convert to Class A shares until eight years after your
          date of purchase of the original shares.

- --------------------------------------------------------------------------------

DISTRIBUTION AND SERVICE (12b-1) FEES

Each AIM Fund (except AIM Tax-Free Intermediate Fund) has adopted 12b-1 plans
that allow the AIM Fund to pay distribution fees to A I M Distributors, Inc.
(the distributor) for the sale and distribution of its shares and fees for
services provided to shareholders, all or a substantial portion of which are
paid to the dealer of record. Because the AIM Fund pays these fees out of its
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.

SALES CHARGES

Generally, you will not pay a sales charge on purchases or redemptions of Class
A shares of AIM Tax-Exempt Cash Fund and AIM Cash Reserve Shares of AIM Money
Market Fund. You may be charged a contingent deferred sales charge if you redeem
AIM Cash Reserve Shares of AIM Money Market Fund acquired through certain
exchanges. Sales charges on all other AIM Funds and classes of those Funds are
detailed below. As used below, the term "offering price" with respect to all
categories of Class A shares includes the initial sales charge.

INITIAL SALES CHARGES

The AIM Funds are grouped into three categories with respect to initial sales
charges. The "Other Information" section of your prospectus will tell you in
what category your particular AIM Fund is classified.

CONTINGENT DEFERRED SALES CHARGES FOR CLASS A SHARES

You can purchase $1,000,000 or more of Class A shares at net asset value.
However, if you purchase shares of that amount in Categories I or II, they will
be subject to a contingent deferred sales charge (CDSC) of 1% if you redeem them
prior to 18 months after the date of purchase. The distributor may pay a dealer
concession and/or a service fee for purchases of $1,000,000 or more.

CONTINGENT DEFERRED SALES CHARGES FOR
CLASS B AND CLASS C SHARES

You can purchase Class B and Class C shares at their net asset value per share.
However, when you redeem them, they are subject to a CDSC in the following
percentages:

- ----------------------------------------------------------
</TABLE>

COMPUTING A CDSC

The CDSC on redemptions of shares is computed based on the lower of their
original purchase price or current market value, net of reinvested dividends and
capital gains distributions. In determining whether to charge a CDSC, we will
assume that you have redeemed shares on which there is no CDSC first and, then,
shares in the order of purchase.

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 consultant must
provide sufficient information at the time of purchase to verify that your
purchase qualifies for such treatment.

REDUCED SALES CHARGES

You may be eligible to buy Class A shares at reduced initial sales charge rates
under Rights of Accumulation or Letters of Intent under certain circumstances.

Rights of Accumulation

You may combine your new purchases of Class A shares with Class A shares
currently owned 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 current
value of all Class A shares you own.

Letters of Intent

Under a Letter of Intent (LOI), you commit to purchase a specified dollar amount
of Class A shares of AIM Funds during a 13-month period. The amount you agree
to purchase determines the initial sales charge you pay. If the full face
amount of the LOI is not invested by the end of the 13-month period, your
account will be adjusted to the higher initial sales charge level for the
amount actually invested.

INITIAL SALES CHARGE EXCEPTIONS

You will not pay initial sales charges

- - on shares purchased by reinvesting dividends and distributions;

- - when exchanging shares among certain AIM Funds;

- - when using the reinstatement privilege; and

- - when a merger, consolidation, or acquisition of assets of an AIM Fund occurs.

CONTINGENT DEFERRED SALES CHARGE (CDSC) EXCEPTIONS

You will not pay a CDSC

- - if you redeem Class B shares you held for more than six years;

- - if you redeem Class C shares you held for more than one year;

- - if you redeem shares acquired through reinvestment of dividends and
  distributions; and

- - on increases in the net asset value of your shares.

There may be other situations when you may be able to purchase or redeem shares

                                 -------------

SPECIAL PLANS

AUTOMATIC INVESTMENT PLAN

You can arrange for periodic investments in any of the AIM Funds by authorizing
the AIM Fund 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. You may stop the
Automatic Investment Plan at any time by giving the transfer agent notice ten
days prior to your next scheduled withdrawal.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic monthly or quarterly
exchanges, if permitted, from one AIM Fund account to one or more other AIM Fund
accounts with the identical registration. 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 10th or 25th day of the month, whichever
you specify, in the amount you specify. The minimum amount you can exchange to
another AIM Fund is $50.

AUTOMATIC DIVIDEND INVESTMENT

All of your dividends and distributions may be paid in cash or invested in any
AIM Fund at net asset value. Unless you specify otherwise, your dividends and
distributions will automatically be reinvested in the same AIM Fund. You may
invest your dividends and distributions (1) into another AIM Fund in the same
class of shares; or (2) from Class A shares into AIM Cash Reserve Shares of AIM
Money Market Fund, or vice versa.

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

(1) Your account balance (a) in the AIM Fund paying the dividend must be at
    least $5,000; or (b) in the AIM Fund receiving the dividend must be at least
    $500;

(2) Both accounts must have identical registration information; and

(3) You must have completed an authorization form to reinvest dividends into
    another AIM Fund.

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 AIM Fund holdings should be rebalanced, on a percentage
basis, between two and ten of your AIM Funds on a quarterly, semiannual or
annual basis. Your portfolio will be rebalanced through the exchange of shares
in one or more of your AIM Funds for shares of the same class of one or more
other AIM Funds in your portfolio. 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. You may realize taxable gains from these
exchanges. We may modify, suspend or terminate the Program at any time on 60
days' prior written notice.

RETIREMENT PLANS

Shares of most of the AIM Funds can be purchased through tax-sheltered
retirement plans made available to corporations, individuals and employees of
non-profit organizations and public schools. A plan document must be adopted
to establish a retirement plan. You may use AIM Funds-sponsored retirement
plans, which include IRAs, Education IRAs, Roth IRAs, 403(b) plans, 401(k)
plans, SIMPLE IRA plans, SEP/SARSEP plans and Money Purchase/Profit Sharing
plans, or another sponsor's retirement plan. The plan custodian of the AIM
Funds-sponsored retirement plan assesses an annual maintenance fee of $10.
Contact your financial consultant for details.

REDEEMING SHARES

REDEMPTION FEES

Generally, we will not charge you any fees to redeem your shares. However, if
you acquired Class A shares of AIM Developing Markets Fund in connection with
the reorganization of AIM Eastern Europe Fund, you will be charged a redemption
fee of 2% of the net asset value of those shares, which will be paid to AIM
Developing Markets Fund, if you redeem your shares within the first year after
the reorganization. Your broker or financial consultant may charge service fees
for handling redemption transactions. Your shares also may be subject to a
contingent deferred sales charge (CDSC).

REDEMPTION OF AIM CASH RESERVE SHARES OF
AIM MONEY MARKET FUND ACQUIRED BY EXCHANGE

If you redeem AIM Cash Reserve Shares acquired by exchange from Class A shares
subject to a CDSC within 18 months of the purchase of the Class A shares, you
will be charged a CDSC.

REDEMPTION OF CLASS B SHARES OR CLASS C
SHARES ACQUIRED BY EXCHANGE FROM AIM CASH
RESERVE SHARES OF AIM MONEY MARKET FUND

We will begin the holding period for purposes of calculating the CDSC on Class B
shares or Class C shares acquired by exchange from AIM Cash Reserve Shares of
AIM Money Market Fund at the time of the exchange into Class B shares or Class C
shares.

REDEMPTION OF CLASS B SHARES ACQUIRED BY
EXCHANGE FROM AIM FLOATING RATE FUND

If you redeem Class B shares you acquired by exchange via a tender offer by AIM
Floating Rate Fund, the early withdrawal charge applicable to shares of AIM
Floating Rate Fund will be applied instead of the CDSC normally applicable to
Class B shares.

                              necessary (see below). The transfer agent may require that
                              you provide additional information, such as corporate
                              resolutions or powers of attorney, if applicable. If you are
                              redeeming from an IRA account, you must include a statement
                              of whether or not you are at least 59 1/2 years old and

                              your proceeds. The transfer agent may require certain other
                              information before you can redeem from an employer-sponsored
                              retirement plan. Contact your employer for details.

By Telephone                  Call the transfer agent. You will be allowed to redeem by
                              telephone if (1) the proceeds are to be mailed to the
                              address on record (if there has been no change communicated
                              to us within the last 30 days) or transferred electronically
                              to a pre-authorized checking account; (2) you do not hold
                              physical share certificates; (3) you can provide proper
                              identification information; (4) the proceeds of the

                              previously declined the telephone redemption privilege.
                              Certain accounts, including retirement accounts and 403(b)
                              plans, may not be redeemed by telephone. The transfer agent
                              must receive your call during the hours the New York Stock
                              Exchange (NYSE) is open for business in order to effect the
                              redemption at that day's closing price.

                              be allowed to redeem by internet if (1) you do not hold

                              retirement accounts may not be redeemed on the internet. The
                              transfer agent must confirm your transaction during the
                              hours the NYSE is open for business in order to effect the
                              redemption at that day's closing price.

- --------------------------------------------------------------------------------

TIMING AND METHOD OF PAYMENT

We normally will send out checks within one business day, and in any event no
more than seven days, after we accept your request to redeem. If you redeem
shares recently purchased by check, you will be required to wait up to ten
business days before we will send your redemption proceeds. This delay is
necessary to ensure that the purchase check has cleared.

REDEMPTION BY MAIL

If you mail us a request in good order to redeem your shares, we will mail you a
check in the amount of the redemption proceeds to the address on record with us.
If your request is not in good order, you may have to provide us with additional
documentation in order to redeem your shares.

REDEMPTION BY TELEPHONE

If you redeem by telephone, we will mail you a check in the amount of the
redemption proceeds to your address of record (if there has been no change
communicated to the transfer agent within the previous 30 days) or transmit them
electronically to your pre-authorized bank account. We use reasonable procedures
to confirm that instructions communicated by telephone are genuine and are not
liable for telephone instructions that are reasonably believed to be genuine.

REDEMPTION BY INTERNET

If you redeem by internet, we will transmit your redemption proceeds
electronically to your pre-authorized bank account. We use reasonable procedures
to confirm that instructions communicated by internet are genuine and are not
liable for internet instructions that are reasonably believed to be genuine.

PAYMENT FOR SYSTEMATIC WITHDRAWALS

You may arrange for regular monthly or quarterly withdrawals from your account
of at least $50. You also may make annual withdrawals if you own Class A shares.
We will redeem enough shares from your account to cover the amount withdrawn.
You must have an account balance of at least $5,000 to establish a Systematic
Withdrawal Plan. You can stop this plan at any time by giving ten days prior
notice to the transfer agent.

EXPEDITED REDEMPTIONS

(AIM Cash Reserve Shares of AIM Money Market Fund only)

If we receive your redemption order before 11:30 a.m. Eastern Time, we will try
to transmit payment of redemption proceeds on that same day. If we receive your
redemption order after 11:30 a.m. Eastern Time and before the close of trading
on the NYSE, we generally will transmit payment on the next business day.

REDEMPTIONS BY CHECK

(Class A shares of AIM Tax-Exempt Cash Fund and AIM Cash Reserve Shares of AIM
Money Market Fund only)

You may redeem shares of these AIM 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.

SIGNATURE GUARANTEES

We require a signature guarantee when you redeem by mail and

(1) the amount is greater than $50,000;

(2) you request that payment be made to someone other than the name registered
    on the account;

(3) you request that payment be sent somewhere other than the bank of record on
    the account; or

(4) you request that payment 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
financial institutions. Call the transfer agent for additional information. Some
institutions have transaction amount maximums for these guarantees. Please check
with the guarantor institution.

REINSTATEMENT PRIVILEGE (Class A shares only)

You may, within 90 days after you sell Class A shares (except Class A shares of
AIM Tax-Exempt Cash Fund), reinvest all or part of your redemption proceeds in
Class A shares of any AIM Fund at net asset value in an identically registered
account. If you sold Class A shares of AIM Limited Maturity Treasury Fund or AIM
Tax-Free Intermediate Fund, you will incur an initial sales charge reflecting
the difference between the initial sales charges on those Funds and the ones in
which you will be investing. In addition, if you paid a contingent deferred
sales charge (CDSC) on any reinstated amount, you will not be subject to a CDSC
if you later redeem that amount. You must notify the transfer agent in writing
at the time you reinstate that you are exercising your reinstatement privilege.
You may exercise this privilege only once per year.

REDEMPTIONS BY THE AIM FUNDS

If your account 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 due to redemptions or
exchanges (excluding retirement accounts), the AIM 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 utilizing the Automatic Investment Plan.

  If an AIM Fund determines that you have provided incorrect information in
opening an account or in the course of conducting subsequent transactions, the
AIM 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 AIM Fund for those
of another AIM Fund. Before requesting an exchange, review the prospectus of the
AIM Fund you wish to acquire. Exchange privileges also apply to holders of the
Connecticut General Guaranteed Account, established for tax-qualified group
annuities, for contracts purchased on or before June 30, 1992.

PERMITTED EXCHANGES

Except as otherwise stated below, you may exchange your shares for shares of the
same class of another AIM Fund. You may exchange AIM Cash Reserve Shares of AIM
Money Market Fund for Class A shares of another AIM Fund, or vice versa. You
also may exchange AIM Cash Reserve Shares of AIM Money Market Fund for Class B
shares or Class C shares of another AIM Fund, but only if the AIM Cash Reserve
Shares were purchased directly and not acquired by exchange. 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 from
Class A shares not subject to a CDSC into Class A shares subject to those
charges, you will be charged a CDSC when you redeem the exchanged shares. The
CDSC charged on redemption of those shares will be calculated starting on the
date you acquired those shares through exchange.

  You also may exchange AIM Cash Reserve Shares of AIM Money Market Fund for
Advisor Class shares, but only if you acquired the AIM Cash Reserve Shares
through an exchange from Advisor Class shares.

YOU WILL NOT PAY A SALES CHARGE WHEN EXCHANGING:

(1) Class A shares with an initial sales charge (except for Class A shares of
    AIM Limited Maturity Treasury Fund and AIM Tax-Free Intermediate Fund) for
    Class A shares of another AIM Fund or AIM Cash Reserve Shares of AIM Money

        Maturity Treasury Fund and AIM Tax-Free Intermediate Fund), but only if
        you acquired the original shares

       (i)  prior to May 1, 1994 by exchange from Class A shares subject to an
            initial sales charge;

(4) Class B shares for other Class B shares, and Class C shares for other Class
    C shares.

(5) AIM Cash Reserve Shares of AIM Money Market Fund for Class B shares and
    Class C shares.

EXCHANGES NOT PERMITTED

You may not exchange Class A shares subject to contingent deferred sales charges
for Class A shares of AIM Limited Maturity Treasury Fund, AIM Tax-Free
Intermediate Fund or AIM Tax-Exempt Cash Fund.

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

- - You must meet the minimum purchase requirements for the AIM Fund into which
  you are exchanging;

- - Shares of the AIM Fund you wish to acquire must be available for sale in your
  state of residence;

- - Exchanges must be made between accounts with identical registration
  information;

- - The account you wish to exchange from must have a certified tax identification
  number (or the Fund has received an appropriate Form W-8 or W-9);

- - Shares must have been held for at least one day prior to the exchange;

- - If you have physical share certificates, you must return them to the transfer
  agent prior to the exchange; and

- - You are limited to a maximum of 10 exchanges per calendar year, because
  excessive short-term trading or market-timing activity can hurt fund
  performance. If you exceed that limit, or if an AIM Fund or the distributor
  determines, in its sole discretion, that your short-term trading is excessive
  or that you are engaging in market-timing activity, it may reject any
  additional exchange orders. An exchange is the movement out of (redemption)
  one AIM Fund and into (purchase) another AIM Fund.

TERMS OF EXCHANGE

Under unusual market conditions, an AIM Fund may delay the purchase of shares
being acquired in an exchange for up to five business days if it determines that
it would be materially disadvantaged by the immediate transfer of exchange
proceeds. There is no fee for exchanges. The exchange privilege is not an option
or right to purchase shares. Any of the participating AIM Funds or the
distributor may modify or discontinue this privilege at any time.

BY MAIL

If you wish to make an exchange by mail, you must include original signatures of
each registered owner exactly as the shares are registered, the account
registration and account number, the dollar amount or number of shares to be
exchanged and the names of the AIM Funds from which and into which the exchange
is to be made.

BY TELEPHONE

Conditions that apply to exchanges by telephone are the same as redemptions by
telephone, including that the transfer agent must receive exchange requests
during the hours the NYSE is open for business; however, you still will be
allowed to exchange by telephone even if you have changed your address of record
within the preceding 30 days.

BY INTERNET

You will be allowed to exchange by internet if (1) you do not hold physical
share certificates; (2) you can provide proper identification information; and
(3) you have established the internet trading option.

EXCHANGING CLASS B AND CLASS C SHARES

If you make an exchange involving Class B or Class C shares, the amount of time
you held the original shares will be added to the holding period of the Class B
or Class C shares, respectively, into which you exchanged for the purpose of
calculating contingent deferred sales charges (CDSC) if you later redeem the
exchanged shares. If you redeem Class B shares acquired by exchange via a tender
offer by AIM Floating Rate Fund, you will be credited with the time period you
held the shares of AIM Floating Rate Fund for the purpose of computing the early
withdrawal charge applicable to those shares.

 EACH AIM FUND AND ITS AGENTS RESERVE THE RIGHT AT ANY TIME TO:

 - REJECT OR CANCEL ANY PART OF ANY PURCHASE OR EXCHANGE ORDER;

 - MODIFY ANY TERMS OR CONDITIONS OF PURCHASE OF SHARES OF ANY AIM FUND;

 - REJECT OR CANCEL ANY REQUEST TO ESTABLISH THE AUTOMATIC INVESTMENT PLAN AND
   SYSTEMATIC WITHDRAWAL PLAN OPTIONS ON THE SAME ACCOUNT; 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 AIM Fund's shares is the fund's net asset value per share. The
AIM Funds value portfolio securities for which market quotations are readily
available at market value. The AIM Funds value short-term investments maturing
within 60 days at amortized cost, which approximates market value. AIM Money
Market Fund and AIM Tax-Exempt Cash Fund value all of their securities at
amortized cost. AIM High Income Municipal Fund, AIM Municipal Bond Fund, AIM
Tax-Exempt Bond Fund of Connecticut 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.

  The AIM Funds value all other securities and assets at their fair value.
Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day. In addition, if,
between the time trading ends on a particular security and the close of the
NYSE, events occur that materially affect the value of the security, the AIM
Funds may value the security at its fair value as determined in good faith by or
under the supervision of the Board of Directors or Trustees of the AIM Fund. The
effect of using fair value pricing is that an AIM Fund's net asset value will be
subject to the judgment of the Board of Directors or Trustees or its designee
instead of being determined by the market. Because some of the AIM Funds may
invest in securities that are primarily listed on foreign exchanges, the value
of those funds' shares may change on days when you will not be able to purchase
or redeem shares.

  Each AIM Fund determines the net asset value of its shares as of the close of
the NYSE on each day the NYSE is open for business. AIM Money Market Fund also
determines its net asset value as of 12:00 noon Eastern Time on each day the
NYSE is open for business.

TIMING OF ORDERS

You can purchase, exchange or redeem shares during the hours the NYSE is open
for business. The AIM Funds price purchase, exchange and redemption orders at
the net asset value calculated after the transfer agent receives an order in
good form. An AIM 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, dividends and distributions you receive are taxable as ordinary
income or long-term capital gains for federal income tax purposes, whether you
reinvest them in additional shares or take them in cash. Distributions are
taxable to you at different rates depending on the length of time the fund holds
its assets. Different tax rates apply to ordinary income and long-term capital
gain distributions, regardless of how long you have held your shares. Every
year, you will be sent information showing the amount of dividends and
distributions you received from each AIM Fund during the prior year.

  Any long-term or short-term capital gains realized from redemptions of AIM
Fund shares will be subject to federal income tax. Exchanges of shares for
shares of another AIM Fund are treated as a sale, and any gain realized on the
transaction will generally be subject to federal income tax.

  INVESTORS IN TAX-EXEMPT FUNDS SHOULD READ THE INFORMATION UNDER THE HEADING
"OTHER INFORMATION -- SPECIAL TAX INFORMATION REGARDING THE FUND" IN THIS
PROSPECTUS.

  The foreign, state and local tax consequences of investing in AIM Fund shares
may differ materially from the federal income tax consequences described above.
You should consult your tax advisor before investing.
