- --------------------------------------------------------------------------------
 
THE FUNDS
 
  AIM Equity Funds, Inc. (the "Company") is a Maryland corporation organized as
an open-end, diversified, series, management investment company. Currently, the
Company offers six series comprising six separate investment portfolios, each of
which pursues unique investment objectives. This Prospectus relates to Class A,
Class B and Class C shares of CHARTER, CONSTELLATION and WEINGARTEN (the "Retail
Class" or "Retail Classes"). The Company also offers other classes of shares in
three other investment portfolios, AIM AGGRESSIVE GROWTH FUND ("AGGRESSIVE
GROWTH"), AIM BLUE CHIP FUND ("BLUE CHIP") and AIM CAPITAL DEVELOPMENT FUND
("CAPITAL DEVELOPMENT") each of which pursues unique investment objectives. All
such other Funds (except AGGRESSIVE GROWTH) offer multiple classes of shares to
different types of investors. The shares of the other Funds of the Company have
different sales charges and expenses, which may affect performance. To obtain
information about AGGRESSIVE GROWTH, BLUE CHIP and CAPITAL DEVELOPMENT call
(800) 347-4246. See "General Information."
 
  The assets of each Fund are invested in a separate portfolio. The classes of
each Fund share a common investment objective and portfolio of investments. The
income from the investment portfolio of a Fund is allocated to each class of the
Fund based on the net assets of such class as of the close of business on the
previous business day, as adjusted for the current day's shareholder activity.
Each class bears proportionately those expenses, such as the advisory fee, that
are allocated to the Fund as a whole and bears separately certain expenses, such
as those associated with the distribution of the shares of such class.
Consequently, the amounts available for payment of dividends and the net asset
value per share of each class will vary. See "General Information."
 
  THE ADVISOR. A I M Advisors, Inc. ("AIM") serves as each Fund's investment
advisor pursuant to a Master Investment Advisory Agreement. AIM, together with
its subsidiaries, advises or manages over 50 investment company portfolios
encompassing a broad range of investment objectives. Under the Master Investment
Advisory Agreement dated February 28, 1997 (the "Master Advisory Agreement"),
AIM receives a fee for its services based on each Fund's average daily net
assets. Under the Master Administrative Services Agreement between the Company
and AIM dated February 28, 1997 (the "Master Administrative Services
Agreement"), AIM may receive reimbursement of its costs to perform certain
accounting and other administrative services to the Funds. Under a Transfer
Agency and Service Agreement, A I M Fund Services, Inc. ("AFS"), AIM's wholly
owned subsidiary and a registered transfer agent, receives a fee for its
provision of transfer agency, dividend distribution and disbursement, and
shareholder services to the Retail Classes of the Funds. Under the Master
Sub-Advisory Agreement dated as of February 28, 1997 (the "Master Sub-Advisory
Agreement") between AIM and A I M Capital Management, Inc. ("AIM Capital"), a
wholly owned subsidiary of AIM, AIM Capital serves as sub-advisor for the Funds
and receives compensation equal to 50% of the amount paid by the Funds to AIM.
The total advisory fees paid by each Fund are higher than those paid by many
other investment companies of all sizes and investment objectives. However, the
effective fee paid by each Fund at its respective current size is lower than the
fees paid by many other funds with similar investment objectives. See
"Management."
 
  PURCHASING SHARES. Investors may select Class A, Class B or Class C shares of
the Funds which are offered by this Prospectus at an offering price that
reflects differing sales charges and expense levels. See "Terms and Conditions
of Purchase of the AIM Funds -- Sales Charges and Dealer Concessions."
 
  CLASS A SHARES -- Shares are offered at net asset value plus any applicable
initial sales charge.
 
  CLASS B SHARES -- Shares are offered at net asset value without an initial
sales charge, and are subject to a maximum contingent deferred sales charge of
5% on certain redemptions made within six years from the date such shares were
purchased. Class B shares automatically convert to Class A shares of the same
Fund eight years following the end of the calendar month in which a purchase was
made. Class B shares are subject to higher expenses than Class A shares.
 
                                        2
<PAGE>   3
 
  CLASS C SHARES -- Shares are offered at net asset value without an initial
sales charge and are subject to a contingent deferred sales charge of 1% on
certain redemptions made within one year from the date such shares were
purchased. Class C shares are subject to higher expenses than Class A shares.
 
  Initial investments in any class of shares must be at least $500 and
additional investments must be at least $50. The minimum initial investment is
modified for investments through tax-qualified retirement plans and accounts
initially established with an Automatic Investment Plan. The distributor of the
Funds' shares is A I M Distributors, Inc. ("AIM Distributors"), P.O. Box 4739,
Houston, TX 77210-4739. See "How to Purchase Shares" and "Special Plans."
 
  SUITABILITY FOR INVESTORS. An investor in Class A, Class B or Class C shares
of CHARTER, CONSTELLATION or WEINGARTEN should consider the method of purchasing
shares that is most beneficial given the amount of the purchase, the length of
time the shares are expected to be held, whether dividends will be paid in cash
or reinvested in additional shares of the Fund and other circumstances.
Investors should consider whether, during the anticipated life of their
investment in the Fund, the accumulated distribution fees and any applicable
contingent deferred sales charges on Class B shares prior to conversion or Class
C shares would be less than the initial sales charge and accumulated
distribution fees on Class A shares purchased at the same time, and to what
extent such differential would be offset by the higher return on Class A shares.
To assist investors in making this determination, the table under the caption
"Table of Fees and Expenses" sets forth examples of the charges applicable to
each class of shares. Class A shares will normally be more beneficial than Class
B shares or Class C to the investor who qualifies for reduced initial sales
charges, as described above. Therefore, AIM Distributors will reject any order
for purchase of more than $250,000 for Class B shares.
 
  EXCHANGE PRIVILEGE. The Funds are among those mutual funds distributed by AIM
Distributors (collectively, "The AIM Family of Funds"). Class A, Class B and
Class C shares of the Funds may be exchanged for shares of other funds in The
AIM Family of Funds in the manner and subject to the policies and charges set
forth herein. See "Exchange Privilege."
 
  REDEEMING SHARES. Class A shareholders of the Funds may redeem all or a
portion of their shares at the respective Fund's net asset value on any business
day, generally without charge. A contingent deferred sales charge of 1% may
apply to certain redemptions where a purchase of more than $1 million is made at
net asset value. See "How to Redeem Shares -- Contingent Deferred Sales Charge
Program for Large Purchases."
 
  Class B shareholders of the Funds may redeem all or a portion of their shares
at net asset value on any business day, less a contingent deferred sales charge
for redemptions made within six years from the date such shares were purchased.
Class B shares redeemed after six years from the date such shares were purchased
will not be subject to any contingent deferred sales charge. See "How to Redeem
Shares -- Multiple Distribution System."
 
  Class C shareholders of the Funds may redeem all or a portion of their shares
at net asset value on any business day, less a 1% contingent deferred sales
charge for redemptions made within one year from the date such shares were
purchased. See "How to Redeem Shares -- Multiple Distribution System."
 
  DISTRIBUTIONS. The Funds currently declare and pay dividends from net
investment income, if any, on a quarterly basis with respect to CHARTER and on
an annual basis with respect to WEINGARTEN and CONSTELLATION. Each Fund makes
distributions of realized capital gains, if any, on an annual basis. Dividends
and distributions of a Fund may be reinvested at current net asset value,
(without payment of a sales charge) in additional shares of such class of the
Fund or may be invested in shares of such class of the other funds in The AIM
Family of Funds. See "Dividends, Distributions and Tax Matters" and "Special
Plans."

TABLE OF FEES AND EXPENSES
 
  The following table is designed to help an investor in any of the Funds
understand the various costs that an investor will bear, both directly and
indirectly. The fees and expenses for the Class A and Class B shares of CHARTER
and WEINGARTEN and the Class A shares of CONSTELLATION set forth in the table
are based on the actual average net assets of each Fund for its 1997 fiscal
year. The fees and expenses for the Class B shares of CONSTELLATION and the
Class C shares of CHARTER, WEINGARTEN and CONSTELLATION set forth in the table
are based on the estimated expenses for the current fiscal year. The rules of
the SEC require that the maximum sales charge be reflected in the table, even
though certain investors may qualify for reduced sales charges. See "How to
Purchase Shares."

 (1)  Purchases of $1 million or more are not subject to an initial sales
      charge. However, a contingent deferred sales charge of 1% applies to
      certain redemptions made within 18 months from the date such shares were
      purchased. See the Investor's Guide, under the caption "How to Redeem
      Shares -- Contingent Deferred Sales Charge Program for Large Purchases."
 
 (2)  As a result of 12b-1 fees, a long-term shareholder may pay more than the
      economic equivalent of the maximum front-end sales charges permitted by
      the rules of the National Association of Securities Dealers, Inc. Given
      the Rule 12b-1 fee of the Fund, however, it is estimated that it would
      take a substantial number of years for a shareholder to exceed such
      maximum front-end sales charges.
 
  *   CHARTER'S, WEINGARTEN'S and CONSTELLATION'S investment advisor is 
      currently waiving a portion of its fees. Had there been no fee waivers
      during the year, management fees would have been 0.63%, 0.63% and 0.63%,
      respectively, of average net assets. There can be no assurance that
      future waivers of fees (if any) will not vary from the figures reflected
      in the table.

PERFORMANCE
 
  Each Fund's performance may be quoted in advertising in terms of yield or
total return. All advertisements of the Funds will disclose the maximum sales
charge (including deferred sales charge) to which investments in shares of the
Funds may be subject. If any advertised performance data does not reflect the
maximum sales charge (if any), such advertisement will disclose that the sales
charge has not been deducted in computing the performance data, and that, if
reflected, the maximum sales charge would reduce the performance quoted. See the
Statement of Additional Information for further details concerning performance
comparisons used in advertisements by the Funds. Further information regarding
each Fund's performance is contained in that Fund's annual report to
shareholders which is available upon request and without charge.
 
  Standardized total return for Class A shares of a Fund reflects the deduction
of the maximum initial sales charge at the time of purchase. Standardized total
return for Class B shares of a Fund reflects the deduction of the maximum
applicable contingent deferred sales charge on a redemption of shares held for
the period. Standardized total return for Class C shares of a Fund reflects the
deduction of a 1% contingent deferred sales charge, if applicable, on a
redemption of shares held for the period.
 
  A Fund's total return shows its overall change in value, including changes in
share price and assuming all the Fund's dividends and capital gain distributions
are reinvested and that all charges and expenses are deducted. A cumulative
total return reflects a Fund's performance over a stated period of time. An
average annual total return reflects the hypothetical annually compounded return
that would have produced the same cumulative total return if the Fund's
performance had been constant over the entire period. BECAUSE AVERAGE ANNUAL
RETURNS TEND TO EVEN OUT VARIATIONS IN A FUND'S RETURN, INVESTORS SHOULD
RECOGNIZE THAT SUCH RETURNS ARE NOT THE SAME AS ACTUAL YEAR-BY-YEAR RESULTS. To
illustrate the components of overall performance, a Fund may separate its
cumulative and average annual returns into income results and capital gain or
loss.
 
  Yield is computed in accordance with a standardized formula described in the
Statement of Additional Information and can be expected to fluctuate from time
to time and is not necessarily indicative of future results. Accordingly, yield
information may not provide a basis for comparison with investments which pay a
fixed rate of interest for a stated period of time. Yield is a function of the
type and quality of a Fund's investments, the Fund's maturity and the Fund's
operating expense ratio.
 
  From time to time and in its discretion, AIM may waive all or a portion of its
advisory fees and/or assume certain expenses of any Fund. Such a practice will
have the effect of increasing that Fund's yield and total return. The
performance of each Fund will vary from time to time and past results are not
necessarily indicative of future results. A Fund's performance is a function of
its portfolio management in selecting the type and quality of portfolio
securities and is affected by operating expenses of the Fund and market
conditions. A shareholder's investment in a Fund is not insured or guaranteed.
These factors should be carefully considered by the investor before making an
investment in any Fund.
 
  Additional performance information is contained in the Statement of Additional
Information and in the Company's Annual Report to Shareholders, both of which
are available upon request without charge.

INVESTMENT PROGRAMS
 
  The Company has six series, each of which is a separate investment portfolio.
Three of the investment portfolios, CHARTER, WEINGARTEN and CONSTELLATION are
discussed herein. Each of the Funds has its own investment objectives and
investment program. There can, of course, be no assurance that any Fund will in
fact achieve its objectives since all investments are inherently subject to
market risks. The Board of Directors of the Company reserves the right to change
any of the investment policies, strategies or practices of any of the Funds, as
described in this Prospectus and in the Statement of Additional Information,
without shareholder approval, except in those instances where shareholder
approval is expressly required.
 
  AIM CHARTER FUND. The primary investment objective of CHARTER is to seek
growth of capital, with current income as a secondary objective. Although the
amount of CHARTER'S current income will vary from time to time, it is
anticipated that the current income realized by CHARTER will generally be
greater than that realized by mutual funds whose sole objective is growth of
capital. CHARTER seeks to achieve its objective by generally investing at least
65% of its net assets in stocks of companies believed by management to have the
potential for above average growth in revenues and earnings. CHARTER generally
will also invest at least 80% of its net assets in securities which pay income
to CHARTER.
 
  AIM WEINGARTEN FUND. The investment objective of WEINGARTEN is to seek growth
of capital principally through investment in common stocks of seasoned and
better capitalized companies. Current income will not be an important criterion
of investment selection, and any such income should be considered incidental. It
is anticipated that common stocks will be the principal form of investment by
the Fund. WEINGARTEN'S portfolio is primarily comprised of securities of two
basic categories of companies: (a) "core" companies, which Fund management
considers to have experienced above-average and consistent long-term growth in
earnings and to have excellent prospects for outstanding future growth, and (b)
"earnings acceleration" companies which Fund management believes are currently
enjoying a dramatic increase in profits. See "Investment Objectives and
Policies" in the Statement of Additional Information.
 
                                       13
<PAGE>   14
 
  AIM CONSTELLATION FUND. The investment objective of CONSTELLATION is to seek
capital appreciation. CONSTELLATION aggressively seeks to increase shareholders'
capital by investing principally in common stocks, with emphasis on medium-sized
and smaller emerging growth companies. Management of the Fund will be
particularly interested in companies that are likely to benefit from new or
innovative products, services or processes that should enhance such companies'
prospects for future growth in earnings. As a result of this policy, the market
prices of many of the securities purchased and held by the Fund may fluctuate
widely. Any income received from securities held by the Fund will be incidental,
and an investor should not consider a purchase of shares of the Fund as
equivalent to a complete investment program. CONSTELLATION'S portfolio is
primarily comprised of securities of two basic categories of companies: (a)
"core" companies, which Fund management considers to have experienced
above-average and consistent long-term growth in earnings and to have excellent
prospects for outstanding future growth, and (b) "earnings acceleration"
companies which Fund management believes are currently enjoying a dramatic
increase in profits. See "Certain Investment Strategies and Policies" below and
"Investment Objectives and Policies" in the Statement of Additional Information.
 
   CERTAIN INVESTMENT STRATEGIES AND POLICIES. In pursuit of their respective
objectives and policies, the Funds may employ one or more of the following
strategies in order to enhance investment results:
 
  TEMPORARY DEFENSIVE MEASURES. A portion of each Fund's assets may be held,
from time to time, in cash, repurchase agreements, commercial paper, U.S.
government obligations, taxable municipal securities, investment grade (high
quality) corporate bonds or other debt securities, when such positions are
deemed advisable in light of economic or market conditions or for daily cash
management purposes. In addition, each of the Funds may invest, for temporary
defensive purposes, all or a substantial portion of their assets in the
securities described above. To the extent that a Fund invests to a significant
degree in these instruments, its ability to achieve its investment objective may
be adversely affected.
 
  REPURCHASE AGREEMENTS. Each of the Funds may enter into repurchase agreements.
A repurchase agreement is an instrument under which the Fund acquires ownership
of a debt security and the seller agrees, at the time of the sale, to repurchase
the obligation at a mutually agreed upon time and price, thereby determining the
yield during the Fund's holding period. With regard to repurchase transactions,
in the event of a bankruptcy or other default of a seller of a repurchase
agreement, a Fund could experience both delays in liquidating the underlying
securities and losses, including: (a) a possible decline in the value of the
underlying security during the period while the Fund seeks to enforce its rights
thereto; (b) possible subnormal levels of income and lack of access to income
during this period; and (c) expenses of enforcing its rights. Repurchase
agreements are considered to be loans by the Fund under the 1940 Act.
 
  REVERSE REPURCHASE AGREEMENTS. Consistent with Charter's policy on borrowings,
Charter may invest in reverse repurchase agreements with banks, which involve
the sale of securities held by the Fund, with an agreement that the Fund will
repurchase the securities at an agreed upon price and date. The 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 it enters into a reverse repurchase
agreement, the Fund will segregate liquid securities having a dollar value equal
to the repurchase price. Reverse repurchase agreements are considered borrowings
by the Fund under the 1940 Act.
 
  U.S. GOVERNMENT SECURITIES. CHARTER may invest in U.S. Government securities,
including, but not limited to, U.S. Treasury obligations, such as Treasury Bills
(maturities of one year or less) or Treasury Notes (maturities of less than
three years). The market value of U.S. Government securities will fluctuate with
changes in interest rate levels. Thus, if interest rates increase from the time
the security was purchased, the market value of the security will decrease.
Conversely, if interest rates decrease, the market value of the security will
increase.
 
  STOCK INDEX FUTURES CONTRACTS. Each of the Funds may purchase and sell stock
index futures contracts. A stock index futures contract is an agreement pursuant
to which two parties agree to take or make delivery of an amount of cash equal
to a specified dollar amount times the difference between the stock index value
at the close of the last trading day of the contract and the price at which the
futures contract is originally struck. Each of the Funds will only enter into
domestic stock index futures. No physical delivery of the underlying stocks in
the index is made. Each of the Funds may purchase and sell futures contracts in
order to hedge the value of its portfolio against changes in market conditions.
Generally, a Fund may elect to close a position in a futures contract by taking
an opposite position which will operate to terminate such Fund's position in the
futures contract. See the Statement of Additional Information for a description
of the Funds' investments in futures contracts, including certain related risks.
The Funds may each purchase or sell futures contracts if, immediately
thereafter, the sum of the amount of margin deposits and premiums on open
positions with respect to futures contracts would not exceed 5% of the market
value of a Fund's total assets.
 
  There are risks associated with investments in stock index futures contracts.
During certain market conditions, purchases and sales of futures contracts may
not completely offset a decline or rise in the value of a Fund's portfolio. In
the futures markets, it may not always be possible to execute a buy or sell
order at the desired price, or to close out an open position due to market
conditions, limits on open positions and/or daily price fluctuations. Changes in
the market value of a Fund's portfolio may differ substantially from the changes
anticipated by the Fund when hedged positions were established, and
unanticipated price movements in a futures contract may result in a loss
substantially greater than a Fund's initial investment in such contract.
Successful use of futures contracts is depen-
 
                                       14
<PAGE>   15
 
dent upon AIM's ability to predict correctly movements in the direction of the
applicable markets. No assurance can be given that AIM's judgment in this
respect will be correct.
 
  WRITING COVERED CALL OPTION AND PURCHASING PUT OPTION CONTRACTS. CHARTER,
WEINGARTEN and CONSTELLATION may write (sell) covered call options. The purpose
of put and covered call option transactions is to hedge against changes in the
market value of a Fund's portfolio securities caused by fluctuating interest
rates, fluctuating currency exchange rates and changing market conditions, and
to close out or offset existing positions in such options or futures contracts
as described below. None of the Funds will engage in such transactions for
speculative purposes.
 
  CHARTER, CONSTELLATION and WEINGARTEN may each write (sell) call options, but
only if such options are covered and remain covered as long as the Fund is
obligated as a writer of the option (seller). Writing a call option obligates a
Fund to sell or deliver the option's underlying security in return for the
strike price upon exercise of the option. A call option is "covered" if a Fund
owns or has the right to acquire the underlying security subject to the call. If
a "covered" call option expires unexercised, the writer realizes a gain in the
amount of the premium received. If the covered call option is exercised, the
writer realizes either a gain or loss from the sale or purchase of the
underlying security with the proceeds to the writer being increased by the
amount of the premium. Prior to its expiration, a call option may be closed out
by means of a purchase of an identical option. Any gain or loss from such
transaction will depend on whether the amount paid is more or less than the
premium received for the option plus related transaction costs.
 
  CHARTER and WEINGARTEN may also purchase puts. By purchasing a put option, a
Fund obtains the right (but not the obligation) to sell the option's underlying
security at a fixed strike price.
 
  Options are subject to certain risks, including the risk of imperfect
correlation between the option and a Fund's other investments and the risk that
there might not be a liquid secondary market for the option when the Fund seeks
to hedge against adverse market movements. In general, options whose strike
prices are close to their underlying securities' current values will have the
highest trading volume, while options whose strike prices are further away may
be less liquid. The liquidity of options may also be affected if options
exchanges impose trading halts, particularly when markets are volatile.
 
  The investment policies of CHARTER, WEINGARTEN and CONSTELLATION permit the
writing of covered call options on securities comprising no more than 25% of the
value of each Fund's net assets. Each Fund's policies with respect to the
writing of call options or the purchase of put options may be changed by the
Company's Board of Directors, without shareholder approval.
 
  ILLIQUID SECURITIES. None of the Funds will invest more than 15% of their net
assets in illiquid securities, including repurchase agreements with maturities
in excess of seven days.
 
  SECURITIES ISSUED ON A WHEN-ISSUED OR DELAYED DELIVERY BASIS. Each Fund may
purchase securities on a "when-issued" basis, that is, delivery of and payment
for the securities is not fixed at the date of purchase, but is set after the
securities are issued (normally within forty-five days after the date of the
transaction). Each Fund also may purchase or sell securities on a delayed
delivery basis. The payment obligation and the interest rate that will be
received on the delayed delivery securities are fixed at the time the buyer
enters into the commitment. A Fund will only make commitments to purchase
when-issued or delayed delivery 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. For further information regarding
securities issued on a when-issued or delayed delivery basis see the caption
"Investment Objectives and Policies" in the Statement of Additional Information.
 
  RULE 144A SECURITIES. Each of the Funds may invest in securities that are
subject to restrictions on resale because they have not been registered under
the Securities Act of 1933 (the "1933 Act"). These securities are sometimes
referred to as private placements. Although securities which may be resold only
to "qualified institutional buyers" in accordance with the provisions of Rule
144A under the 1933 Act are unregistered securities, the Funds may each purchase
Rule 144A securities without regard to the limitation on investments in illiquid
securities described above under "Illiquid Securities," provided that a
determination is made that such securities have a readily available trading
market. AIM will determine the liquidity of Rule 144A securities under the
supervision of the Company's Board of Directors. The liquidity of Rule 144A
securities will be monitored by AIM and, if as a result of changed conditions,
it is determined that a Rule 144A security is no longer liquid, a Fund's
holdings of illiquid securities will be reviewed to determine what, if any,
action is required to assure that the Fund does not exceed its applicable
percentage limitation for investments in illiquid securities.
 
  INVESTMENT IN UNSEASONED ISSUERS. CHARTER may purchase securities in
unseasoned issuers. Securities in such issuers may provide opportunities for
long term capital growth. Greater risks are associated with investments in
securities of unseasoned issuers than in the securities of more established
companies because unseasoned issuers have only a brief operating history and may
have more limited markets and financial resources.
 
  INVESTMENT IN OTHER INVESTMENT COMPANIES. Each of the Funds may invest in
other investment companies to the extent permitted by the Investment Company Act
of 1940, and rules and regulations thereunder, and, if applicable, exemptive
orders granted by the SEC.
 
  FOREIGN SECURITIES. To the extent consistent with their respective investment
objectives, each of the Funds may invest in foreign securities. It is not
anticipated that such foreign securities, which may be payable in foreign
currencies and traded abroad, will constitute more than 20% of the value of each
Fund's respective total assets. For purposes of computing such limitation,
American Deposi-

tary Receipts ("ADRs"), European Depositary Receipts ("EDRs") and other
securities representing underlying securities of foreign issuers are treated as
foreign securities. To the extent a Fund invests in securities denominated in
foreign currencies, each Fund bears the risk of changes in the exchange rates
between U.S. currency and the foreign currency, as well as the availability and
status of foreign securities markets. These securities will be marketable equity
securities (including common and preferred stock, depositary receipts for stock
and fixed income or equity securities exchangeable for or convertible into
stock) of foreign companies which generally are listed on a recognized foreign
securities exchange or traded in a foreign over-the-counter market. Each of the
Funds may also invest in foreign securities listed on recognized U.S. securities
exchanges or traded in the U.S. over-the-counter market. Such foreign securities
may be issued by foreign companies located in developing countries in various
regions of the world. A "developing country" is a country in the initial stages
of its industrial cycle. As compared to investment in the securities markets of
developed countries, investment in the securities markets of developing
countries involves exposure to markets that may have substantially less trading
volume and greater price volatility, economic structures that are less diverse
and mature, and political systems that may be less stable. For a discussion of
the risks pertaining to investments in foreign obligations, see "Risk Factors
Regarding Foreign Securities" below.
 
  RISK FACTORS REGARDING FOREIGN SECURITIES. Investments by a Fund in foreign
securities, whether denominated in U.S. currencies or foreign currencies, may
entail all of the risks set forth below. Investments by a Fund in ADRs, EDRs or
similar securities also may entail some or all of the risks as set forth below.
 
  Currency Risk. The value of each Fund's foreign investments will be affected
by changes in currency exchange rates. The U.S. dollar value of a foreign
security decreases when the value of the U.S. dollar rises against the foreign
currency in which the security is denominated, and increases when the value of
the U.S. dollar falls against such currency.
 
  Political and Economic Risk. The economies of many of the countries in which
the Funds may invest are not as developed as the United States economy and may
be subject to significantly different forces. Political or social instability,
expropriation or confiscatory taxation, and limitations on the removal of funds
or other assets could also adversely affect the value of each Fund's
investments.
 
  Regulatory Risk. Foreign companies are not registered with the SEC and are
generally not subject to the regulatory controls imposed on United States
issuers and, as a consequence, there is generally less publicly available
information about foreign securities than is available about domestic
securities. Foreign companies are not subject to uniform accounting, auditing
and financial reporting standards, practices and requirements comparable to
those applicable to domestic companies. Income from foreign securities owned by
the Funds may be reduced by a withholding tax at the source, which tax would
reduce dividend income payable to the Funds' shareholders.
 
  Market Risk. The securities markets in many of the countries in which the
Funds invest will have substantially less trading volume than the major United
States markets. As a result, the securities of some foreign companies may be
less liquid and experience more price volatility than comparable domestic
securities. Increased custodian costs as well as administrative costs (such as
the need to use foreign custodians) may be associated with the maintenance of
assets in foreign jurisdictions. There is generally less government regulation
and supervision of foreign stock exchanges, brokers and issuers which may make
it difficult to enforce contractual obligations. In addition, transaction costs
in foreign securities markets are likely to be higher, since brokerage
commission rates in foreign countries are likely to be higher than in the United
States.
 
  PORTFOLIO TURNOVER. Any particular security will be sold, and the proceeds
reinvested, whenever such action is deemed prudent from the viewpoint of a
Fund's investment objectives, regardless of the holding period of that security.
Each Fund's historical portfolio turnover rates are included in the Financial
Highlights tables herein. A higher rate of portfolio turnover may result in
higher transaction costs, including brokerage commissions. Also, to the extent
that higher portfolio turnover results in a higher rate of net realized capital
gains to a Fund, the portion of the Fund's distributions constituting taxable
capital gains may increase.
 
  For a discussion of AIM's brokerage allocation policies and practices, see
"Portfolio Transactions and Brokerage" in the Statement of Additional
Information. In accordance with policies established by the Board of Directors,
AIM may take into account sales of shares of the Funds and other funds advised
by AIM in selecting broker-dealers to effect portfolio transactions on behalf of
the Funds.
 
  The investment objectives and policies stated above are not fundamental
policies of the Funds and may be changed by the Board of Directors of the
Company without shareholder approval. Shareholders will be notified before any
material change in the investment policies stated above become effective.
 
  INVESTMENT RESTRICTIONS.  Each of the Funds has adopted a number of investment
restrictions, including the following:
 
  BORROWING. Each of the Funds may borrow money to a limited extent from banks
(including the Funds' custodian bank) for temporary or emergency purposes.
CHARTER and WEINGARTEN may each borrow amounts of up to 10% of their respective
total assets and may each pledge amounts of up to 20% of their respective total
assets to secure such borrowings. In addition, the Funds have adopted a
non-fundamental policy stating that no Fund will purchase additional securities
when any borrowings from banks exceed 5% of the Fund's total assets.
 
  In addition to the ability to borrow money for temporary or emergency
purposes, CONSTELLATION may, but has no current intention to, borrow money from
banks to purchase or carry securities. CONSTELLATION may borrow amounts to
purchase or carry securities only if, immediately after such borrowing, the
value of its assets, including the amount borrowed, less its liabilities, is
equal to at least 300% of the amount borrowed, plus all outstanding borrowings.
Any investment gains made by CONSTELLATION with the borrowed
 
                                       16
<PAGE>   17
 
monies in excess of interest paid by the Fund will cause the net asset value of
the Fund's shares to rise faster than would otherwise be the case. On the other
hand, if the investment performance of the additional securities purchased with
the proceeds of such borrowings fails to cover the interest paid on the money
borrowed by the Fund, the net asset value of the Fund will decrease faster than
would otherwise be the case. This speculative factor is known as "leveraging."
 
  LENDING OF FUND SECURITIES. Each of the Funds may also lend its portfolio
securities in amounts up to 33 1/3% of the total assets of the respective Funds.
Such loans could involve risks of delay in receiving additional collateral in
the event the value of the collateral decreased below the value of the
securities loaned or of delay in recovering the securities loaned or even loss
of rights in the collateral should the borrower of the securities fail
financially. However, loans will be made only to borrowers deemed by AIM to be
of good standing and only when, in AIM's judgment, the income to be earned from
the loans justifies the attendant risks.
 
  Except where otherwise noted, the foregoing investment restrictions are
matters of fundamental policy and may not be changed without shareholder
approval. For additional investment restrictions applicable to the Funds, see
the Statement of Additional Information.

MANAGEMENT
 
  The overall management of the business and affairs of the Funds is vested with
the Company's Board of Directors. The Board of Directors approves all
significant agreements between the Company and persons or companies furnishing
services to a Fund, including the Master Advisory Agreement with AIM, the Master
Sub-Advisory Agreement between AIM and AIM Capital with respect to the Funds,
the Master Administrative Services Agreement with AIM, the Master Distribution
Agreement with AIM Distributors as the distributor of the shares of the Retail
Classes of the Funds, the Custodian Agreement with State Street Bank and Trust
Company as custodian and the Transfer Agency and Service Agreement with AFS as
transfer agent. The day-to-day operations of each Fund are delegated to its
officers and to AIM, subject always to the objectives and policies of the Fund
and to the general supervision of the Company's Board of Directors. Information
concerning the Board of Directors may be found in the Statement of Additional
Information. Certain directors and officers of the Company are affiliated with
AIM and A I M Management Group Inc. ("AIM Management"), the parent corporation
of AIM. AIM Management is a holding company engaged in the financial services
business and is an indirect wholly owned subsidiary of AMVESCAP PLC. AMVESCAP
PLC and its subsidiaries are an independent investment management group engaged
in institutional investment management and retail mutual fund businesses in the
United States, Europe and the Pacific Region.
 
  For a discussion of AIM Management and its subsidiaries' Year 2000 Compliance
Project, see "General Information -- Year 2000 Compliance Project."
 
  INVESTMENT ADVISOR. AIM, 11 Greenway Plaza, Suite 100, Houston, Texas
77046-1173, serves as the investment advisor to each Fund pursuant to the Master
Advisory Agreement. AIM was organized in 1976, and, together with its
subsidiaries, advises or manages over 50 investment company portfolios
(including the Funds) encompassing a broad range of investment objectives. AIM
is a wholly owned subsidiary of AIM Management.
 
  Under the terms of the Master Advisory Agreement, AIM supervises all aspects
of the Funds' operations and provides investment advisory services to the Funds.
AIM obtains and evaluates economic, statistical and financial information to
formulate and implement investment programs for the Funds. AIM will not be
liable to the Funds or their shareholders except in the case of AIM's willful
misfeasance, bad faith, gross negligence or reckless disregard of duty;
provided, however that AIM may be liable for certain breaches of duty under the
1940 Act.
 
  For a discussion of AIM's brokerage allocation policies and practices, see
"Portfolio Transactions and Brokerage" in the Statement of Additional
Information. In accordance with policies established by the directors, AIM may
take into account sales of shares of the Funds and other funds advised by AIM in
selecting broker-dealers to effect portfolio transactions on behalf of the
Funds.
 
  ADMINISTRATOR. The Company has entered into a Master Administrative Services
Agreement effective as of February 28, 1997 with AIM, pursuant to which AIM has
agreed to provide or arrange for the provision of certain accounting and other
administrative services to the Funds, including the services of a principal
financial officer of the Funds and related staff. As compensation to AIM for its
services under the Master Administrative Services Agreements, the Funds
reimburse AIM for expenses incurred by AIM or its subsidiaries in connection
with such services.
 
  SUB-ADVISOR. AIM Capital, 11 Greenway Plaza, Suite 100, Houston, TX
77046-1173, serves as sub-advisor to the Funds pursuant to the Master
Sub-Advisory Agreement between AIM and AIM Capital. Under the terms of the
Master Sub-Advisory Agreement, AIM has appointed AIM Capital to provide certain
investment advisory services for each of the Funds, subject to overall
supervision by AIM and the Company's Board of Directors. AIM Capital is a wholly
owned subsidiary of AIM. Certain of the directors and officers of AIM Capital
are also executive officers of the Company.
 
  FEE WAIVERS. AIM may in its discretion from time to time agree to waive
voluntarily all or any portion of its advisory fee and/or assume certain
expenses of any Fund but will retain its ability to be reimbursed prior to the
end of the fiscal year.
 
                                       17
<PAGE>   18
 
  ADVISORY FEES. As compensation for its services AIM is paid an investment
advisory fee, which is calculated separately for each Fund. AIM received total
advisory fees from CHARTER, WEINGARTEN and CONSTELLATION for the fiscal year
ended October 31, 1997 which represented 0.62%, 0.60% and 0.61%, respectively,
of each of such Fund's average daily net assets. For the fiscal year ended
October 31, 1997, with respect to CHARTER, CONSTELLATION and WEINGARTEN, AIM
voluntarily waived 0.01%, 0.03% and 0.02%, respectively, of each such Fund's
advisory fee. Had there been no fee waivers during the year, advisory fees would
have been 0.63%, 0.63% and 0.63%, respectively, of average daily net assets. As
compensation for its services, AIM Capital receives a fee from AIM equal to 50%
of the fees received by AIM under the Master Advisory Agreement on behalf of the
Funds.
 
  AIM received reimbursement of administrative services costs with respect to
CHARTER, WEINGARTEN and CONSTELLATION for the fiscal year ended October 31, 1997
which represented 0.003%, 0.003% and 0.002%, respectively, of each such Fund's
average daily net assets. Total expenses for a Class A share of the Retail Class
for the fiscal year ended October 31, 1997, stated as a percentage of average
net assets of each of Retail Class of CHARTER, WEINGARTEN and CONSTELLATION were
1.09%, 1.07% and 1.11%, respectively.
 
  In addition, the Company and AFS, P.O. Box 4739, Houston, TX 77210-4739, a
wholly owned subsidiary of AIM and registered transfer agent, have entered into
the Transfer Agency and Service Agreement, pursuant to which AFS provides
transfer agency, dividend distribution and disbursement, and shareholder
services to the Retail Classes of the Funds.
 
  DISTRIBUTOR. The Company has entered into a Master Distribution Agreement,
dated August 2, 1997 on behalf of Class A and Class C shares of the Funds, and
has entered into a Master Distribution Agreement, dated February 28, 1997, on
behalf of Class B shares of the Funds (individually referred to as the
"Distribution Agreement" or collectively as the "Distribution Agreements.") with
AIM Distributors, a registered broker-dealer and a wholly owned subsidiary of
AIM, to act as the distributor of Class A, Class B and Class C shares of the
Funds. Certain directors and officers of the Company are affiliated with AIM
Distributors.
 
  The Distribution Agreements provide AIM Distributors with the exclusive right
to distribute shares of the Retail Classes of the Funds directly and through
institutions with whom AIM Distributors has entered into selected dealer
agreements. Under the Distribution Agreement for the Class B shares, AIM
Distributors sells Class B shares of the Funds at net asset value subject to a
contingent deferred sales charge established by AIM Distributors. AIM
Distributors is authorized to advance to institutions through whom Class B
shares are sold a sales commission under schedules established by AIM
Distributors. The Distribution Agreement for the Class B shares provides that
AIM Distributors (or its assignee or transferee) will receive 0.75% (of the
total 1.00% payable under the distribution plan applicable to Class B shares) of
each Fund's average daily net assets attributable to Class B shares attributable
to the sales efforts of AIM Distributors. In the event the Class B shares
Distribution Agreement is terminated, AIM Distributors would continue to receive
payments of asset based sales charges in respect of the outstanding Class B
shares attributable to the distribution efforts of AIM Distributors; provided,
however, that a complete termination of the Class B shares master distribution
plan (as defined in the plan) would terminate all payments to AIM Distributors.
Termination of the Class B shares distribution plan or Distribution Agreement
does not affect the obligation of Class B shareholders to pay contingent
deferred sales charges.
 
  DISTRIBUTION PLANS. Class A and C Plan. The Company has adopted a Master
Distribution Plan applicable to Class A and Class C shares of each Fund (the
"Class A and C Plan") pursuant to Rule 12b-1 under the 1940 Act, to compensate
AIM Distributors for the purpose of financing any activity that is intended to
result in the sale of Class A and Class C shares of each Fund.
 
  Under the Class A and C Plan, the Company may compensate AIM Distributors an
aggregate amount of 0.30% of the average daily net assets of Class A shares of
each Fund on an annualized basis and an aggregate amount of 1.00% of the average
daily net assets of Class C shares of each Fund on an annualized basis.
 
  The Class A and C Plan is designed to compensate AIM Distributors, on a
quarterly basis, for certain promotional and other sales-related costs, and to
implement a dealer incentive program which provides for periodic payments to
selected dealers who furnish continuing personal shareholder services to their
customers who purchase and own Class A or Class C shares of a Fund. Payments can
also be directed by AIM Distributors to selected institutions who have entered
into service agreements with respect to Class A and Class C shares of each Fund
and who provide continuing personal services to their customers who own Class A
and Class C shares of the Fund. The service fees payable to selected
institutions are calculated at the annual rate of 0.25% of the average daily net
asset value of those Fund shares that are held in such institution's customers'
accounts which were purchased on or after a prescribed date set forth in the
Plan.
 
  Of the aggregate amount payable under the Class A and C Plan, payments to
dealers and other financial institutions that provide continuing personal
shareholder services to their customers who purchase and own shares of the Fund,
in amounts of up to 0.25% of the average net assets of the Fund attributable to
the customers of such dealers or financial institutions are characterized as a
service fee, and payments to dealers and other financial institutions in excess
of such amount and payments to AIM Distributors would be characterized as an
asset-based sales charge pursuant to the Class A and C Plan. The Class A and C
Plan also imposes a cap on the total amount of sales charges, including
asset-based sales charges, that may be paid by the Company with respect to the
Fund. The Class A and C Plan does not obligate the Fund to reimburse AIM
Distributors for the actual expenses AIM Distributors may incur in fulfilling
its obligations under the Class A and C Plan on behalf of the Fund. Thus, under
the Class A and C Plan, even if AIM Distributors' actual expenses exceed the fee
payable to AIM Distributors thereunder at any given time, the Fund will not be
obligated to pay more than that fee. If AIM Distributors' expenses are less than
the fee it receives, AIM Distributors will retain the full amount of the fee.
Payments pursuant to the Plans are subject to any applicable limitations imposed
by rules of the National Association of Securities Dealers, Inc.
 
                                       18
<PAGE>   19
 
  Class B Plan. The Company has also adopted a master distribution plan
applicable to Class B shares of the Fund (the "Class B Plan"). Under the Class B
Plan, each Fund pays distribution expenses at an annual rate of 1.00% of the
average daily net assets attributable to such Fund's Class B shares. Of such
amount each Fund pays a service fee of 0.25% of the average daily net assets
attributable to such Fund's Class B shares to selected dealers and financial
institutions who furnish continuing personal shareholder services to their
customers who purchase and own Class B shares of the Fund. Any amounts not paid
as a service fee would constitute an asset-based sales charge. Amounts paid in
accordance with the Class B Plan with respect to any Fund may be used to finance
any activity primarily intended to result in the sale of Class B shares of such
Fund.
 
  Activities that may be financed under the Class A and C Plan and the Class B
Plan (collectively, the "Plans") include, but are not limited to: 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, expense 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 the cost of administering the Plans. These amounts
payable by a Fund under the Plans need not be directly related to the expenses
actually incurred by AIM Distributors on behalf of each Fund. Thus, even if AIM
Distributors' actual expenses exceed the fee payable to AIM Distributors
thereunder at any given time, the Company will not be obligated to pay more than
that fee, and if AIM Distributors' expenses are less than the fee it receives,
AIM Distributors will retain the full amount of the fee. Payments pursuant to
the Plans are subject to any applicable limitations imposed by rules of the
National Association of Securities Dealers, Inc.
 
  Each of the Plans may be terminated at any time by a vote of the majority of
those directors who are not "interested persons" of the Company or by a vote of
the holders of the majority of the outstanding shares of the applicable class.
 
  Under the Plans, AIM Distributors may in its discretion from time to time
agree to waive voluntarily all or any portion of its 12b-1 fee, while retaining
its ability to be reimbursed for such fee prior to the end of each fiscal year.
 
  Under the Plans, certain financial institutions which have entered into
service agreements and which sell shares of the Fund on an agency basis, may
receive payments from the Funds pursuant to the respective Plans. AIM
Distributors does not act as principal, but rather as agent, for the Fund in
making such payments. The Funds will obtain a representation from such financial
institutions that they will either be licensed as dealers as required under
applicable state law, or that they will not engage in activities which would
constitute acting as a "dealer" as defined under applicable state law. Financial
intermediaries and any other person entitled to receive compensation for selling
Fund shares may receive different compensation for selling shares of one class
over another.
 
  For additional information concerning the operation of the Plans see the
Statement of Additional Information.
 
PORTFOLIO MANAGERS
 
  AIM uses a team approach and a disciplined investment process in providing
investment advisory services to all of its accounts, including the Funds. AIM's
investment staff consists of approximately 135 individuals. While individual
members of AIM's investment staff are assigned primary responsibility for the
day-to-day management of each of AIM's accounts, all accounts are reviewed on a

- --------------------------------------------------------------------------------
 
ORGANIZATION OF THE COMPANY
 
  The Company was organized in 1988 as a Maryland corporation, and is registered
with the SEC as a diversified, open-end, series, management investment company.
The Company consists of six separate portfolios: CHARTER, CONSTELLATION and
WEINGARTEN, each of which has retail classes of shares consisting of Class A,
Class B and Class C shares and an Institutional Class; AGGRESSIVE GROWTH, which
has a retail class of shares consisting of Class A shares; and BLUE CHIP and
CAPITAL DEVELOPMENT, each of which has retail classes of shares consisting of
Class A, Class B and Class C shares. The Company's common stock is classified
into nineteen different classes. Each class represents an interest in one of six
portfolios.
 
  Each class of shares of the same Fund represents interests in that Fund's
assets and have identical voting, dividend, liquidation and other rights on the
same terms and conditions, except that each class of shares bears differing
class-specific expenses, such as those associated with the shareholder servicing
of their shares, is subject to differing sales loads, conversion features and
exchange privileges, and has exclusive voting rights on matters pertaining to
that class' distribution plan.
 
  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 different classes of shares,
where applicable, of a Fund. However, on matters affecting one portfolio of the
Company or one class of shares, a separate vote of shareholders of that
portfolio or class is required. Shareholders of a portfolio or class are not
entitled to vote on any matter which does not affect that portfolio or class but
which requires a separate vote of another portfolio or class. An example of a
matter which would be voted on separately by shareholders of a portfolio is the
approval of an advisory agreement, and an example of a matter which would be
voted on separately by shareholders of a class of shares is approval of a
distribution plan. When issued, shares of each Fund are fully paid and
nonassessable, have no preemptive or subscription rights, and are fully
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 directors,
holders of more than 50% of the shares voting for the election of directors can
elect all of the directors of the Company, and the holders of less than 50% of
the shares voting for the election of directors will not be able to elect any
directors.
 
  The holder of shares of each Fund is entitled to such dividends payable out of
the net assets allocable to such Fund as may be declared by the Board of
Directors of the Company. In the event of liquidation or dissolution of the
Company, the holders of shares of each Fund will be entitled to receive pro
rata, subject to the rights of creditors, the net assets of the Company
allocable to the Fund. Fractional shares of each Fund have the same rights as
full shares to the extent of their proportionate interest.
 
  Under Maryland law and the Company's By-Laws, the Company need not hold an
annual meeting of shareholders unless a meeting is required under the 1940 Act
to elect directors. Shareholders may remove directors from office, and a meeting
of shareholders may be called at the request of the holders of 10% or more of
the Company's outstanding shares. As of February 2, 1998, Merrill Lynch Pierce
Fenner & Smith owned beneficially (for its clients) and of record 31.18% of the
outstanding Class C shares of Constellation. As long as Merrill Lynch Pierce
Fenner & Smith owns over 25% of such shares, it may be presumed to be in
"control" as defined in the 1940 Act.

  There is no sales charge on purchases of $1,000,000 or more; however, AIM
Distributors may pay a dealer concession and/or advance a service fee on such
transactions.
 
  ALL GROUPS OF AIM FUNDS. 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 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 Securities Act of 1933.
 
  In addition to amounts paid to dealers as a dealer concession out of the
initial sales charge paid by investors, AIM Distributors may, from time to time,
at its expense or as an expense for which it may be compensated under a
distribution plan, if applicable, pay a bonus or other consideration or
incentive to dealers who sell a minimum dollar amount of the shares of the AIM
Funds during a specified period of time. In some instances, these incentives may
be offered only to certain dealers who have sold or may sell significant amounts
of shares. At the option of the dealer, such incentives may take the form of
payment for travel expenses, including lodging, incurred in connection with
trips taken by qualifying registered representatives and their families to
places within or outside the United States. The total amount of such additional
bonus payments or other consideration shall not exceed 0.25% of the public
offering price of the shares sold. Any such bonus or incentive programs will not
change the price paid by investors for the purchase of the applicable AIM Fund's
shares or the amount that any particular AIM Fund will receive as proceeds from
such sales. Dealers may not use sales of the AIM Funds' shares to qualify for
any incentives to the extent that such incentives may be prohibited by the laws
of any state.
 
  AIM Distributors may make payments to dealers and institutions who are dealers
of record for purchases of $1 million or more of Class A shares (or shares which
normally involve payment of initial sales charges), which are sold at net asset
value and are subject to a contingent deferred sales charge, for all AIM Funds
other than Class A shares of each of AIM LIMITED MATURITY TREASURY FUND and AIM
TAX-FREE INTERMEDIATE FUND as follows: 1% of the first $2 million of such
purchases, plus 0.80% of the next $1 million of such purchases, plus 0.50% of
the next $17 million of such purchases, plus 0.25% of amounts in excess of $20
million of such purchases. See "Contingent Deferred Sales Charge Program for
Large Purchases." AIM Distributors may make payments to dealers and institutions
who are dealers of record for purchases of $1 million or more of Class A shares
(or shares which normally involve payment of initial sales charges), and which
are sold at net asset value and are not subject to a contingent deferred sales
charge, in an amount up to 0.10% of such purchases of Class A shares of AIM
LIMITED MATURITY TREASURY FUND, and in an amount up to 0.25% of such purchases
of Class A shares of AIM TAX-FREE INTERMEDIATE FUND.
 
  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 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 AIM Distributors under the Class B Plan which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of such sales commissions plus financing costs.
 
  AIM Distributors may pay sales commissions to dealers and institutions who
sell Class C shares of the AIM Funds 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. 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 AIM Distributors
under the Class A and C Plan attributable to Class C shares which constitutes an
asset-based sales charge (0.75%) is intended in part to permit AIM Distributors
to recoup a portion of on-going sales commissions to dealers plus financing
costs, if any. After the first full year, AIM Distributors will make such
payments quarterly 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 commissions
are not paid on sales to investors exempt from the CDSC, including shareholders
of record on April 30, 1995 who purchase additional shares in any of the Funds
on or after May 1, 1995, and in circumstances where AIM Distributors grants an
exemption on particular transactions.

                                                                       MCF-02/98

  TIMING OF PURCHASE ORDERS. Orders for the purchase of shares of an AIM Fund
(other than AIM MONEY MARKET FUND, as described below) received prior to the
close of the New York Stock Exchange ("NYSE"), which is generally 4:00 p.m.
Eastern Time (and which is hereinafter referred to as "NYSE Close") on any
business day of an AIM Fund will be confirmed at the price next determined.
Orders received after NYSE Close will be confirmed at the price determined on
the next business day of the AIM Fund. It is the responsibility of the dealer to
ensure that all orders are transmitted on a timely basis to the Transfer Agent.
Any loss resulting from the dealer's failure to submit an order within the
prescribed time frame will be borne by that dealer. Please see "How to Purchase
Shares -- Purchases by Wire" for information on obtaining a reference number for
wire orders, which will facilitate the handling of such orders and ensure prompt
credit to an investor's account. A "business day" of an AIM Fund is any day on
which the NYSE is open for business. It is expected that the NYSE will be closed
during the next twelve months on Saturdays and Sundays and on the days on which
New Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day
are observed by the NYSE.
 
  An investor who uses a check to purchase shares will be credited with the full
number of shares purchased at the time of receipt of the purchase order, as
previously described. However, in the event of a redemption or exchange of such
shares, the investor may be required to wait up to ten business days before the
redemption proceeds are sent. This delay is necessary in order to ensure that
the check has cleared. If the check does not clear, or if any investment order
must be cancelled due to nonpayment, the investor will be responsible for any
resulting loss to an AIM Fund or to AIM Distributors.
 
  SPECIAL INFORMATION RELATING TO MULTIPLE CLASS FUNDS. The Multiple Class Funds
currently offer two or more classes of shares through separate distribution
systems (the "Multiple Distribution System"). Although each class of shares of a
particular Multiple Class Fund represents an interest in the same portfolio of
investments, each class is subject to a different distribution structure and, as
a result, differing expenses. This Multiple Distribution System allows investors
to select the class that is best suited to the investor's needs and objectives.
In considering the options afforded by the Multiple Distribution System,
investors should consider both the applicable initial sales charge or contingent
deferred sales charge, as well as the ongoing expenses borne by each class of
shares and other relevant factors, such as whether his or her investment goals
are long-term or short-term.
 
     CLASS A SHARES are sold subject to the initial sales charges described
     above and are subject to the other fees and expenses described herein.
     Class A shares of AIM MONEY MARKET FUND are designed to meet the needs of
     an investor who wishes to establish a dollar cost averaging program,
     pursuant to which Class A shares an investor owns may be exchanged at net
     asset value for Class A shares of another Multiple Class Fund or shares of
     another AIM Fund which is not a Multiple Class Fund, subject to the terms
     and conditions described under the caption "Exchange Privilege -- Terms and
     Conditions of Exchanges."
 
     CLASS B SHARES are sold without an initial sales charge. Thus, the entire
     purchase price of Class B shares is immediately invested in Class B shares.
     Class B shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
     per annum on the average daily net assets of a Multiple Class Fund
     attributable to Class B shares. See the discussion under the caption
     "Management -- Distribution Plans." In addition, Class B shares redeemed
     within six years from the date such shares were purchased are subject to a
     contingent deferred sales charge ranging from 5% for redemptions made
     within the first year to 1% for redemptions made within the sixth year. No
     contingent deferred sales charge will be imposed if Class B shares are
     redeemed after six years from the date such shares were purchased.
     Redemptions of Class B shares and associated charges are further described
     under the caption "How to Redeem Shares -- Multiple Distribution System."
 
     Class B shares will automatically convert into Class A shares of the same
     Multiple Class Fund (together with a pro rata portion of all Class B shares
     acquired through the reinvestment of dividends and distributions) eight
     years from the end of the calendar month in which the purchase of Class B
     shares was made. Following such conversion of their Class B shares,
     investors will be relieved of the higher Rule 12b-1 Plan payments
     associated with Class B shares. See "Management -- Distribution Plans."
 
     CLASS C SHARES are sold without an initial sales charge. Thus the entire
     purchase price of Class C shares is immediately invested in Class C shares.
     Class C shares are subject, however, to Rule 12b-1 Plan payments of 1.00%
     per annum on the average daily net assets of a Multiple Class Fund
     attributable to Class C shares. See the discussion under the caption
     "Management -- Distribution Plans." In addition, Class C shares redeemed
     within one year from the date such shares were purchased are subject to a
     1.00% contingent deferred sales charge. No contingent deferred sales charge
     will be imposed if Class C shares are redeemed after one year from the date
     such shares were purchased. Redemptions of Class C shares and associated
     charges are further described under the caption "How to Redeem
     Shares -- Multiple Distribution System."
 
     AIM Cash Reserve Shares of AIM MONEY MARKET FUND are sold without an
     initial sales charge and are not subject to a contingent deferred sales
     charge; however, they are subject to the other fees and expenses described
     in the prospectus for AIM MONEY MARKET FUND.
 
  TIMING OF PURCHASE, EXCHANGE AND REDEMPTION ORDERS (AIM MONEY MARKET FUND
ONLY). Orders for purchases, exchanges and redemptions of shares of AIM MONEY
MARKET FUND received prior to 12:00 noon Eastern Time or NYSE Close on any
business day of the Fund will be confirmed at the price next determined. Net
asset value is normally determined at 12:00 noon Eastern Time and NYSE Close on
each business day of AIM MONEY MARKET FUND.

                                                                       MCF-02/98

  SPECIAL INFORMATION RELATING TO AIM MONEY MARKET FUND AND AIM TAX-EXEMPT CASH
FUND (THE "MONEY MARKET FUNDS"). Because each Money Market Fund uses the
amortized cost method of valuing the securities it holds and rounds its per
share net asset value to the nearest whole cent, it is anticipated that the net
asset value of the shares of such funds will remain constant at $1.00 per share.
However, there is no assurance that each Money Market Fund can maintain a $1.00
net asset value per share. In order to earn dividends with respect to AIM MONEY
MARKET FUND on the same day that a purchase is made, purchase payments in the
form of federal funds must be received by the Transfer Agent before 12:00 noon
Eastern Time on that day. Purchases made by payments in any other form, or
payments in the form of federal funds received after such time but prior to NYSE
Close, will begin to earn dividends on the next business day following the date
of purchase. The Money Market Funds generally will not issue share certificates
but will record investor holdings in noncertificate form and regularly advise
the shareholder of his ownership position.
 
  SHARE CERTIFICATES. Share certificates for all AIM Funds will be issued upon
written request by a shareholder to AIM Distributors or the Transfer Agent.
Otherwise, such shares will be held on the shareholder's behalf by the
applicable AIM Fund(s) and be recorded on the books of such fund(s). See
"Exchange Privilege -- Exchanges by Telephone" and "How to Redeem
Shares -- Redemptions by Telephone" for restrictions applicable to shares issued
in certificate form. Please note that certificates will not be issued for shares
held in prototype retirement plans.
 
  MINIMUM ACCOUNT BALANCE. If (1) an account opened in a fund has been in effect
for at least one year and the shareholder has not made an additional purchase in
that account within the preceding six calendar months and (2) the value of such
account drops below $500 for three consecutive months as a result of redemptions
or exchanges, the fund has the right to redeem the account, after giving the
shareholder 60 days' prior written notice, unless the shareholder makes
additional investments within the notice period to bring the account value up to
$500. If a fund determines that a shareholder has provided incorrect information
in opening an account with a fund or in the course of conducting subsequent
transactions with the fund related to such account, the fund may, in its
discretion, redeem the account and distribute the proceeds of such redemption to
the shareholder.
 
REDUCTIONS IN INITIAL SALES CHARGES
 
  Reductions in the initial sales charges shown in the sales charge tables
(quantity discounts) apply to purchases of shares of the AIM Funds that are
otherwise subject to an initial sales charge, provided that such purchases are
made by a "purchaser" as hereinafter defined. Purchases of Class A shares of AIM
TAX-EXEMPT CASH FUND, AIM Cash Reserve Shares of AIM MONEY MARKET FUND and Class
B and Class C shares of the Multiple Class Funds will not be taken into account
in determining whether a purchase qualifies for a reduction in initial sales
charges.
 
  The term "purchaser" means:

  - an individual and his or her spouse and children, including any trust
    established exclusively for the benefit of any such person; or a pension,
    profit-sharing, or other benefit plan established exclusively for the
    benefit of any such person, such as an IRA, Roth IRA, a single-participant
    money-purchase/profit-sharing plan or an individual participant in a 403(b)
    Plan (unless such 403(b) plan qualifies as the purchaser as defined below);

  - a 403(b) plan, the employer/sponsor of which is an organization described
    under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended
    (the "Code"), provided that:
 
        a. the employer/sponsor must submit contributions for all participating
           employees in a single contribution transmittal (i.e., the funds will
           not accept contributions submitted with respect to individual
           participants);
 
        b. each transmittal must be accompanied by a single check or wire
           transfer; and
 
        c. all new participants must be added to the 403(b) plan by submitting
           an application on behalf of each new participant with the
           contribution transmittal;
 
  - a trustee or fiduciary purchasing for a single trust, estate or single
    fiduciary account (including a pension, profit-sharing or other employee
    benefit trust created pursuant to a plan qualified under Section 401 of the
    Code) and 457 plans, although more than one beneficiary or participant is
    involved;

  - a Simplified Employee Pension ("SEP"), Salary Reduction and other Elective
    Simplified Employee Pension account ("SARSEP"), a Savings Incentive Match
    Plans for Employees IRA ("SIMPLE IRA") where the employer has notified AIM
    Distributors in writing that all of its related employee SEP, SARSEP or
    SIMPLE IRA accounts should be linked;

  - any other organized group of persons, whether incorporated or not, provided
    the organization has been in existence for at least six months and has some
    purpose other than the purchase at a discount of redeemable securities of a
    registered investment company; or
 
  - the discretionary advised accounts of A I M Advisors, Inc. ("AIM") or A I M
    Capital Management, Inc. ("AIM Capital").
 
  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. AIM Distributors reserves the right to determine whether
any purchaser is entitled, by vir-

                                                                       MCF-02/98
                                      A-6
<PAGE>   27
 
tue of the foregoing definition, to the reduced sales charge. No person or
entity may distribute shares of the AIM Funds without payment of the applicable
sales charge other than to persons or entities who qualify for a reduction in
the sales charge as provided herein.
 
  (1) LETTERS OF INTENT. A purchaser, as previously defined, may pay reduced
initial sales charges by completing the appropriate section of the account
application and by fulfilling a Letter of Intent ("LOI"). 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. The LOI confirms such purchaser's intention as to the
total investment to be made in shares of the AIM Funds (except for
(i) Class A shares of AIM TAX-EXEMPT CASH FUND, and AIM Cash Reserve Shares of
AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the Multiple Class
Funds) within the following 13 consecutive months. By marking the LOI section on
the account application and by signing the account application, the purchaser
indicates that he understands and agrees to the terms of the LOI and is bound by
the provisions described below.
 
  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 the total dollar amount indicated by the LOI, as
described under "Sales Charges and Dealer Concessions." 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 under "Rights of Accumulation" if the
Transfer Agent is advised of all other accounts at the time of the investment.
Shares acquired through reinvestment of dividends and capital gains
distributions will not be applied to the LOI. At any time during the 13-month
period after meeting the original obligation, a purchaser may revise his
intended investment amount upward by submitting a written and signed request.
Such a revision will not change the original expiration date. 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 investor will pay the increased amount of sales charge as
described below. Purchases made within 90 days before signing an LOI will be
applied toward completion of the LOI. The LOI effective date will be the date of
the first purchase within the 90-day period. The Transfer Agent will process
necessary adjustments upon the expiration or completion date of the LOI.
Purchases made more than 90 days before signing an LOI will be applied toward
completion of the LOI based on the value of the shares purchased calculated at
the public offering price on the effective date of the LOI.
 
  To assure compliance with the provisions of the 1940 Act, out of the initial
purchase (or subsequent purchases if necessary) the Transfer Agent will escrow
in the form of shares an appropriate dollar amount (computed to the nearest full
share). 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 amount actually purchased. If the
purchaser does not pay such difference within 20 days of the expiration date, he
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.
 
  If at any time before completing the LOI Program, the purchaser wishes to
cancel the agreement, he must give written notice to AIM Distributors. 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, a
cancellation of the LOI will automatically be effected. 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.
 
  (2) RIGHTS OF ACCUMULATION. A "purchaser," as previously defined, may also
qualify for reduced initial sales charges based upon such purchaser's existing
investment in shares of any of the AIM Funds (except for (i) Class A shares of
AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of AIM MONEY MARKET FUND
and (ii) Class B and Class C shares of the Multiple Class Funds) at the time of
the proposed purchase. 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. To determine
whether or not a reduced initial sales charge applies to a proposed purchase,
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
(except for (i) Class A shares of AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve
Shares of AIM MONEY MARKET FUND and (ii) Class B and Class C shares of the
Multiple Class Funds) owned by such purchaser, calculated at their then current
public offering price. If a purchaser so qualifies for a reduced sales charge,
the reduced sales charge applies to the total amount of money then being
invested by such purchaser and not just to the portion that exceeds the
breakpoint above which a reduced sales charge applies. 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 AFS 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.
 
  PURCHASES AT NET ASSET VALUE. Purchases of shares of any of the AIM Funds at
net asset value (without payment of an initial sales charge) may be made in
connection with: (a) the reinvestment of dividends and distributions from a fund
(see "Dividends,

                                                                       MCF-02/98
                                      A-7
<PAGE>   28
 
Distributions and Tax Matters"); (b) exchanges of shares of certain other funds
(see "Exchange Privilege"); (c) use of the reinstatement privilege (see "How to
Redeem Shares"); or (d) a merger, consolidation or acquisition of assets of a
fund.
 
  Shareholders of record of Class A shares of AIM WEINGARTEN FUND and AIM
CONSTELLATION FUND on September 8, 1986, and shareholders of record of Class A
shares of AIM CHARTER FUND on November 17, 1986, may purchase additional Class A
shares of the particular AIM Fund(s) whose shares they owned on such date, at
net asset value (without payment of a sales charge) for as long as they
continuously own Class A shares of such AIM Fund(s) having a market value of at
least $500. In addition, discretionary advised clients of any investment
advisors whose clients held Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND on September 8, 1986, or who held Class A shares of AIM
CHARTER FUND on November 17, 1986, and have held such Class A shares at all
times subsequent to such date, may purchase Class A shares of the applicable AIM
Fund(s) at the net asset value of such shares.

  The following persons may purchase shares of the AIM Funds through AIM
Distributors without payment of an initial sales charge: (a) A I M Management
Group Inc. ("AIM Management") and its affiliated companies; (b) any current or
retired officer, director, trustee or employee, or any member of the immediate
family (including spouse, children, parents and parents of spouse) of any such
person, of AIM Management or its affiliates or of certain mutual funds which are
advised or managed by AIM, or any trust established exclusively for the benefit
of such persons; (c) any employee benefit plan established for employees of AIM
Management or its affiliates; (d) any current or retired officer, director,
trustee or employee, or any member of the immediate family (including spouse,
children, parents and parents of spouse) of any such person, or of CIGNA
Corporation or of any of its affiliated companies, or of First Data Investor
Services Group (formerly The Shareholders Services Group, Inc.); (e) any
investment company sponsored by CIGNA Investments, Inc. or any of its affiliated
companies for the benefit of its directors' deferred compensation plans; (f)
discretionary advised clients of AIM or AIM Capital; (g) registered
representatives and employees of dealers who have entered into agreements with
AIM Distributors (or financial institutions that have arrangements with such
dealers with respect to the sale of shares of the AIM Funds) and any member of
the immediate family (including spouse, children, parents and parents of spouse)
of any such person, provided that purchases at net asset value are permitted by
the policies of such person's employer; (h) certain broker-dealers, investment
advisers or bank trust departments that provide asset allocation, similar
specialized investment services or investment company transaction services for
their customers, that charge a minimum annual fee for such services, and that
have entered into an agreement with AIM Distributors with respect to their use
of the AIM Funds in connection with such services; and (i) employees of
Triformis Inc.

  In addition, shares of any AIM Fund may be purchased at net asset value,
without payment of a sales charge, by pension, profit-sharing or other employee
benefit plans created pursuant to a plan qualified under Section 401 of the Code
or plans under Section 457 of the Code, or employee benefit plans created
pursuant to Section 403(b) of the Code and sponsored by nonprofit organizations
defined under Section 501(c)(3) of the Code. Such plans will qualify for
purchases at net asset value provided that (1) the total amount invested in the
plan is at least $1,000,000, (2) the sponsor signs a $1,000,000 LOI, (3) such
shares are purchased by an employer-sponsored plan with at least 100 eligible
employees, or (4) all of the plan's transactions are executed through a single
financial institution or service organization who has entered into an agreement
with AIM Distributors with respect to their use of the AIM Funds in connection
with such accounts. Section 403(b) plans sponsored by public educational
institutions will not be eligible for net asset value purchases based on the
aggregate investment made by the plan or the number of eligible employees.
Participants in such plans will be eligible for reduced sales charges based
solely on the aggregate value of their individual investments in the applicable
AIM Fund. PLEASE NOTE THAT TAX-EXEMPT FUNDS ARE NOT APPROPRIATE INVESTMENTS FOR
SUCH PLANS. AIM Distributors may pay investment dealers or other financial
service firms for share purchases of the Load Funds (as defined on page A-10
herein) sold at net asset value to an employee benefit plan in accordance with
this paragraph as follows: 1% of the first $2 million of such purchases, plus
0.80% of the next $1 million of such purchases, plus 0.50% of the next $17
million of such purchases, plus 0.25% of amounts in excess of $20 million of
such purchases and up to 0.10% of the net asset value of any Class A shares of
AIM LIMITED MATURITY TREASURY FUND sold at net asset value to an employee
benefit plan in accordance with this paragraph.
 
  Class A shares of AIM WEINGARTEN FUND and AIM CONSTELLATION FUND may be
deposited at net asset value, without payment of a sales charge, in G/SET series
unit investment trusts, whose portfolios consist exclusively of Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND and stripped United States
Treasury issued notes or bonds bearing no current interest ("Treasury
Obligations"). Class A shares of such funds may also be purchased at net asset
value by other unit investment trusts approved by the Board of Directors of AIM
Equity Funds, Inc. Unit holders of such trusts may elect to invest cash
distributions from such trusts in Class A shares of AIM WEINGARTEN FUND or AIM
CONSTELLATION FUND at net asset value, including: (a) distributions of any
dividend income or other income received by such trusts; (b) distributions of
any net capital gains received in respect of Class A shares of AIM WEINGARTEN
FUND or AIM CONSTELLATION FUND and proceeds of the sale of Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND used to redeem units of such trusts;
and (c) proceeds from the maturity of the Treasury Obligations at the
termination dates of such trusts. Prior to the termination dates of such trusts,
a unit holder may invest the proceeds from the redemption or repurchase of his
units in Class A shares of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND at net
asset value, provided: (a) that the investment in Class A shares of AIM
WEINGARTEN FUND or AIM CONSTELLATION FUND is effected within 30 days of such
redemption or repurchase; and (b) that the unit holder or his dealer provides
AIM Distributors with a letter which: (i) identifies the name, address and
telephone number of the dealer who sold to the unit holder the units to be
redeemed or repurchased; and (ii) states that the investment in Class A shares
of AIM WEINGARTEN FUND or AIM CONSTELLATION FUND is being funded exclusively by
the proceeds from the redemption or repurchase of units of such trusts.

                                                                       MCF-02/98

  FOR ANY FUND NAMED ON THE COVER PAGE OF THIS PROSPECTUS, AIM DISTRIBUTORS AND
ITS AGENTS RESERVE THE RIGHT AT ANY TIME (1) TO WITHDRAW ALL OR ANY PART OF THE
OFFERING MADE BY THIS PROSPECTUS; (2) TO REJECT ANY PURCHASE OR EXCHANGE ORDER
OR TO CANCEL ANY PURCHASE DUE TO NONPAYMENT OF THE PURCHASE PRICE; (3) TO
INCREASE, WAIVE OR LOWER THE MINIMUM INVESTMENT REQUIREMENTS; OR (4) TO MODIFY
ANY OF THE TERMS OR CONDITIONS OF PURCHASE OF SHARES OF SUCH FUND. For any fund
named on the cover page, AIM Distributors and its agents will use their best
efforts to provide notice of any such actions through correspondence with
broker-dealers and existing shareholders, supplements to the AIM Funds'
prospectuses, or other appropriate means, and will provide sixty (60) days'
notice in the case of termination or material modification to the exchange
privilege discussed under the caption "Exchange Privilege."
 
- --------------------------------------------------------------------------------
 
SPECIAL PLANS
 
  Except as noted below, each AIM Fund provides the special plans described
below for the convenience of its shareholders. Once established, there is no
obligation to continue to invest through a plan, and a shareholder may terminate
a plan at any time.
 
  Special plan applications and further information, including details of any
fees which are charged to a shareholder investing through a plan, may be
obtained by written request, directed to AFS at the address provided under "How
to Purchase Shares," or by calling the Client Services Department of AFS at
(800) 959-4246. IT IS RECOMMENDED THAT A SHAREHOLDER CONSIDERING ANY OF THE
PLANS DESCRIBED HEREIN CONSULT A TAX ADVISOR BEFORE COMMENCING PARTICIPATION IN
SUCH A PLAN.

  SYSTEMATIC WITHDRAWAL PLAN. Under a Systematic Withdrawal Plan, a shareholder
who owns shares which are not subject to a contingent deferred sales charge, can
arrange for monthly, quarterly or annual amounts (but not less than $50) to be
drawn against the balance of his account in the designated AIM Fund.
Shareholders who own shares subject to a contingent deferred sales charge, can
only arrange for monthly or quarterly withdrawals under a Systematic Withdrawal
Plan. Payment of this amount can be made on any day of the month the shareholder
specifies, except the thirtieth or thirty-first day of each month in which a
payment is to be made. A minimum account balance of $5,000 is required to
establish a Systematic Withdrawal Plan, but there is no requirement thereafter
to maintain any minimum investment. With respect to shares subject to a
contingent deferred sales charge (all classes) no contingent deferred sales
charge will be imposed on withdrawals made under a Systematic Withdrawal Plan,
provided that the amounts withdrawn under such a plan do not exceed on an annual
basis 12% of the account value at the time the shareholder elects to participate
in the Systematic Withdrawal Plan. Systematic Withdrawal Plans with respect to
shares subject to a contingent deferred sales charge that exceed on an annual
basis 12% of such account will be subject to a contingent deferred sales charge
on the amounts exceeding 12% of the account value at the time the shareholder
elects to participate in the Systematic Withdrawal Plan.

  Under a Systematic Withdrawal Plan, all shares are to be held by the Transfer
Agent and all dividends and distributions are reinvested in shares of the
applicable AIM Fund by the Transfer Agent. To provide funds for payments made
under the Systematic Withdrawal Plan, the Transfer Agent redeems sufficient full
and fractional shares at their net asset value in effect at the time of each
such redemption.
 
  Payments under a Systematic Withdrawal 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 shares
(other than Class B or Class C Shares of the Multiple Class Funds and AIM Cash
Reserve Shares of AIM MONEY MARKET FUND), it is disadvantageous to effect such
purchases while a Systematic Withdrawal Plan is in effect.
 
  The Systematic Withdrawal Plan may be terminated at any time upon 10 days'
prior notice to AFS. Each AIM Fund bears its share of the cost of operating the
Systematic Withdrawal Plan. Each AIM Fund reserves the right to initiate a fee
for each withdrawal (not to exceed its cost), but there is no present intent to
do so.

  AUTOMATIC INVESTMENT PLAN. Shareholders who wish to make regular systematic
investments may establish an Automatic Investment Plan. Under this plan each
withdrawal is made from the shareholder's bank account in the amount specified 
by the shareholder (minimum $50 per investment, per account) and on a day or
date(s) specified by the shareholder. The proceeds are invested in shares of the
designated AIM Fund at the applicable offering price determined on the date of
the withdrawal. An Automatic Investment Plan may be discontinued upon 10 days'
prior notice to the Transfer Agent or AIM Distributors.

  AUTOMATIC DIVIDEND INVESTMENT PLAN. Shareholders may elect to have all
dividends and distributions declared by an AIM Fund paid in cash or invested at
net asset value, without payment of an initial sales charge, either in shares of
the same AIM Fund or invested in shares of another AIM Fund. For each of the
Multiple Class Funds, dividends and distributions attributable to Class A shares
may be reinvested in Class A shares of the same fund, in Class A shares of
another Multiple Class Fund or in shares of another AIM Fund which is not a
Multiple Class Fund; dividends and distributions attributable to Class B shares
may be reinvested in Class B shares of the same fund or in Class B shares of
another Multiple Class Fund; dividends and distributions attributable to Class C
shares may be reinvested in Class C shares of the same fund or in Class C shares
of another Multiple Class Fund; and dividends and distributions attributable to
AIM Cash Reserve Shares of AIM MONEY MARKET FUND may be reinvested in additional
shares of such fund, in Class A shares of another Multiple Class Fund or in
shares of another AIM Fund which is not a Multiple Class Fund. See "Dividends,
Distributions and

Tax Matters -- Dividends and Distributions" for a description of payment dates
for these options. In order to qualify to have dividends and distributions of
one AIM Fund invested in shares of another AIM Fund, the following conditions
must be satisfied: (a) the shareholder must have an account balance in the
dividend paying fund of at least $5,000; (b) the account must be held in the
name of the shareholder (i.e., the account may not be held in nominee name); and
(c) the shareholder must have requested and completed an authorization relating
to the reinvestment of dividends into another AIM Fund. An authorization may be
given on the account application or on an authorization form available from AIM
Distributors. An AIM Fund will waive the $5,000 minimum account value
requirement if the shareholder has an account in the fund selected to receive
the dividends and distributions with a value of at least $500.
 
  DOLLAR COST AVERAGING. Shareholders may elect to have a specified amount
automatically exchanged, either monthly or quarterly (on or about the 10th or
25th day of the applicable month), from one of their accounts into one or more
AIM Funds, subject to the terms and conditions described under the caption
"Exchange Privilege -- Terms and Conditions of Exchanges." The account from
which exchanges are to be made must have a value of at least $5,000 when a
shareholder elects to begin this program, and the exchange minimum is $50 per
transaction. All of the accounts that are part of this program must have
identical registrations. The net asset value of shares purchased under this
program may vary, and may be more or less advantageous than if shares were not
exchanged automatically. There is no charge for entering the Dollar Cost
Averaging program. Sales charges may apply, as described under the caption
"Exchange Privilege."

  PROTOTYPE RETIREMENT PLANS. The AIM Funds (except for AIM HIGH INCOME
MUNICIPAL FUND, AIM MUNICIPAL BOND FUND, AIM TAX-FREE INTERMEDIATE FUND, AIM
TAX-EXEMPT CASH FUND and AIM TAX-EXEMPT BOND FUND OF CONNECTICUT) have made the
following prototype retirement plans available to corporations, individuals and
employees of non-profit organizations and public schools: combination
money-purchase/profit-sharing plans; 403(b) plans; IRA plans; Roth IRA plans;
SARSEP plans; SEP plans; and SIMPLE IRA plans (collectively, "retirement
accounts"). Information concerning these plans, including the custodian's fees
and the forms necessary to adopt such plans, can be obtained by calling or
writing the AIM Funds or AIM Distributors. Shares of the AIM Funds are also
available for investment through existing 401(k) plans (for both individuals and
employers) adopted under the Code. The plan custodian currently imposes an
annual $10 maintenance fee with respect to each retirement account for which it
serves as the custodian. This fee is generally charged in December. Each AIM
Fund and/or the custodian reserve the right to change this maintenance fee and
to initiate an establishment fee (not to exceed its cost).
 
                                                                       MCF-02/98

Funds -- Sales Charges and Dealer Concessions," shares of certain of the AIM
Funds, including the Class A shares of the Multiple Class Funds, listed below
and referred to herein as the "Load Funds," are sold at a public offering price
that includes a maximum sales charge of 5.50% or 4.75% of the public offering
price of such shares; Class A shares (or shares which normally involve the
payment of initial sales charges) of certain of the AIM Funds, listed below and
referred to herein as the "Lower Load Funds," are sold at a public offering
price that includes a maximum sales charge of 1.00% of the public offering price
of such shares; and Class A shares or shares of certain other funds, listed
below and referred to herein as the "No Load Funds," are sold at net asset
value, without payment of a sales charge.

  An exchange is permitted only in the following circumstances: (a) if the funds
offer more than one class of shares, the exchange must be between the same class
of shares (e.g., Class A, Class B and Class C shares of a Multiple Class Fund
cannot be exchanged for each other), except that AIM Cash Reserve Shares of AIM
MONEY MARKET FUND may be exchanged for Class A, Class B, or Class C shares of
another Multiple Class Fund; (b) the dollar amount of the exchange must be at
least equal to the minimum investment applicable to the shares of the fund
acquired through such exchange; (c) the shares of the fund acquired through
exchange must be qualified for sale in the state in which the shareholder
resides; (d) the exchange must be made between accounts having identical
registrations and addresses; (e) the full amount of the purchase price for the
shares being exchanged must have already been received by the fund; (f) the
account from which shares have been exchanged must be coded as having a
certified taxpayer identification number on file or, in the alternative, an
appropriate Internal Revenue Service ("IRS") Form W-8 (certificate of foreign
status) or Form W-9 (certifying exempt status) must have been received by the
fund; (g) newly acquired shares (through either an initial or subsequent
investment) are held in an account for at least ten business days, and all other
shares are held in an account for at least one day, prior to the exchange; and
(h) certificates representing shares must be returned before shares can be
exchanged. There is no fee for exchanges among the AIM Funds.
 
  THE CURRENT PROSPECTUS OF EACH OF THE AIM FUNDS AND CURRENT INFORMATION
CONCERNING THE OPERATION OF THE EXCHANGE PRIVILEGE ARE AVAILABLE THROUGH AIM
DISTRIBUTORS OR THROUGH ANY DEALER WHO HAS EXECUTED AN APPLICABLE AGREEMENT WITH
AIM DISTRIBUTORS. BEFORE EXCHANGING SHARES, INVESTORS SHOULD REVIEW THE
PROSPECTUSES OF THE FUNDS WHOSE SHARES WILL BE ACQUIRED THROUGH EXCHANGE.
EXCHANGES OF SHARES ARE CONSIDERED TO BE SALES FOR FEDERAL AND STATE INCOME TAX
PURPOSES AND MAY RESULT IN A TAXABLE GAIN OR LOSS TO A SHAREHOLDER.
 
  THE EXCHANGE PRIVILEGE IS NOT AN OPTION OR RIGHT TO PURCHASE SHARES BUT IS
PERMITTED UNDER THE RESPECTIVE POLICIES OF THE PARTICIPATING FUNDS, AND MAY BE
MODIFIED OR DISCONTINUED BY ANY OF SUCH FUNDS OR BY AIM DISTRIBUTORS AT ANY
TIME, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT NOTICE.
 
  Shares of any AIM Fund (other than AIM MONEY MARKET FUND) to be exchanged are
redeemed at their net asset value as determined at NYSE Close on the day that an
exchange request in proper form (described below) is received. Exchange requests
received

                                                                       MCF-02/98
                                      A-12
<PAGE>   33
 
after NYSE Close will result in the redemption of shares at their net asset
value at NYSE Close on the next business day. See "Terms and Conditions of
Purchase of the AIM Funds -- Timing of Purchase, Exchange and Redemption Orders
(AIM MONEY MARKET FUND only)" for information regarding the timing of exchange
orders for AIM MONEY MARKET FUND. 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 (See "Dividends, Distributions and
Tax Matters -- Dividends and Distributions," below), 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. Shares purchased by check may not be exchanged until it is determined
that the check has cleared, which may take up to ten business days from the date
that the check is received. See "Terms and Conditions of Purchase of the AIM
Funds -- Timing of Purchase Orders."
 
  In the event of unusual market conditions, AIM Distributors reserves the right
to reject any exchange request, if, in the judgment of AIM Distributors, the
number of requests or the total value of the shares that are the subject of the
exchange places a material burden on a fund. For example, the number of
exchanges by investment managers making market timing exchanges may be limited.
 
  EXCHANGES BY MAIL. Investors exchanging their shares by mail should send a
written request to AFS. The request should contain the account registration and
account number, the dollar amount or number of shares to be exchanged, and the
names of the funds from which and into which the exchange is to be made. The
request should comply with all of the requirements for redemption by mail,
except those required for redemption of IRAs. See "How to Redeem Shares."
 
  EXCHANGES BY TELEPHONE. Shareholders or their agents may request an exchange
by telephone. If a shareholder does not wish to allow telephone exchanges by any
person in his account, he should decline that option on the account application.
AIM Distributors has made arrangements with certain dealers and investment
advisory firms to accept telephone instructions to exchange shares between any
of the AIM Funds. AIM Distributors reserves the right to impose conditions on
dealers or investment advisors who make telephone exchanges of shares of the
funds, including the condition that any such dealer or investment advisor enter
into an agreement (which contains additional conditions with respect to
exchanges of shares) with AIM Distributors. To exchange shares by telephone, a
shareholder, dealer or investment advisor who has satisfied the foregoing
conditions must call AFS at (800) 959-4246. If a shareholder is unable to reach
AFS by telephone, he may also request exchanges by telegraph or use overnight
courier services to expedite exchanges by mail, which will be effective on the
business day received by the Transfer Agent as long as such request is received
prior to NYSE Close. The Transfer Agent and AIM Distributors will not be liable
for any loss, expense or cost arising out of any telephone exchange request that
they reasonably believe to be genuine, but may in certain cases be liable for
losses due to unauthorized or fraudulent transactions if they do not follow
reasonable procedures for verification of telephone transactions. Such
reasonable procedures 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 transaction.
 
  EXCHANGES OF CLASS B AND CLASS C SHARES. A contingent deferred sales charge
will not be imposed in connection with exchanges among Class B shares or among
Class C shares. For purposes of determining a shareholder's holding period of
Class B or Class C shares in the calculation of the applicable contingent
deferred sales charge, the period of time during which Class B or Class C shares
were held prior to an exchange will be added to the holding period of the
applicable Class B or Class C shares acquired in an exchange.
 
- --------------------------------------------------------------------------------
 
HOW TO REDEEM SHARES
 
  Shares of the AIM Funds may be redeemed directly through AIM Distributors or
through any dealer who has entered into an agreement with AIM Distributors. In
addition to the obligation of the fund(s) named on the cover page to redeem
shares, AIM Distributors also repurchases shares. Although a contingent deferred
sales charge may be applicable to certain redemptions, as described below, there
is no redemption fee imposed when shares are redeemed or repurchased; however,
dealers may charge service fees for handling repurchase transactions.
 
  MULTIPLE DISTRIBUTION SYSTEM. Class B shares. Class B shares purchased under
the Multiple Distribution System may be redeemed on any business day of a
Multiple Class Fund at the net asset value per share next determined following
receipt of the redemption order, as described under the caption "Timing and
Pricing of Redemption Orders," less the applicable contingent deferred sales
charge shown in the table below. No deferred sales charge will be imposed (i) on
redemptions of Class B shares following six years from the date such shares were
purchased, (ii) on Class B shares acquired through reinvestments of dividends
and distributions attrib-
                                                                       MCF-02/98
                                      A-13

utable to Class B shares or (iii) on amounts that represent capital appreciation
in the shareholder's account above the purchase price of the Class B shares.

  In determining whether a contingent deferred sales charge is applicable, it
will be assumed that a redemption is made first, of any shares held in the
shareholder's account that are not subject to such charge; second, of shares
derived from reinvestment of dividends and distributions; third, of shares held
for more than six years from the date such shares were purchased; and fourth, of
shares held less than six years from the date such shares were purchased. The
applicable sales charge will be applied against the lesser of the current market
value of shares redeemed or their original cost.
 
  Class C Shares. Class C shares purchased under the Multiple Distribution
System may be redeemed on any business day of a Multiple Class Fund at the net
asset value per share next determined following receipt of the redemption order,
as described under the caption "Timing and Pricing of Redemption Orders," less a
1% contingent deferred sales charge. No deferred sales charge will be imposed
(i) on redemptions of Class C shares following one year from the date such
shares were purchased; (ii) on Class C shares acquired through reinvestment of
dividends and distributions attributable to Class C shares; (iii) on amounts
that represent capital appreciation in the shareholder's account above the
purchase price of the Class C shares; (iv) on redemptions of additional
purchases of shares of AIM ADVISOR FLEX FUND, AIM ADVISOR INTERNATIONAL VALUE
FUND, AIM ADVISOR LARGE CAP VALUE FUND, AIM ADVISOR MULTIFLEX FUND, and AIM

  Waivers. Contingent deferred sales charges on Class B and Class C shares will
be waived on redemptions (1) following the death or post-purchase disability, as
defined in Section 72(m)(7) of the Code, of a shareholder or a settlor of a
living trust (provided AIM Distributors is notified of such death or
post-purchase disability at the time of the redemption request and is provided
with satisfactory evidence of such death or post-purchase disability), (2) in
connection with certain distributions from individual retirement accounts,
custodial accounts maintained pursuant to Code Section 403(b), deferred
compensation plans qualified under Code Section 457 and plans qualified under

in Class B or Class C shares at the time the shareholder elects to participate
in the Systematic Withdrawal Plan, (4) effected pursuant to the right of a
Multiple Class Fund to liquidate a shareholder's account if the aggregate net
asset value of shares held in the account is less than the designated minimum
account size described in the prospectus of such Multiple Class Fund, (5)
effected by AIM of its investment in Class B or Class C shares and (6) of Class
C shares where such investor's dealer of record, due to the nature of the
investor's account, notifies AIM Distributors prior to the time of investment
that the dealer waives the payment otherwise payable to the dealer described in
the fifth paragraph under the caption "Terms and Conditions of Purchase of the
AIM Funds -- All Groups of AIM Funds."
 
  Waiver category (1) above applies only to redemptions of Class B or Class C
shares held at the time of death or initial determination of post-purchase
disability.
 
  Waiver category (2) above applies only to redemptions resulting 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 which does not exceed 12% annually of the
     participant's or beneficiary's account value in a particular AIM Fund;
 
          (ii) in kind transfers of assets where the participant or beneficiary
     notifies AIM Distributors of such transfer no later than the time such
     transfer occurs;

     Plan invested in Class B or Class C shares of one or more Multiple Class

  CONTINGENT DEFERRED SALES CHARGE PROGRAM FOR LARGE PURCHASES. Except for
purchases of Class B and Class C shares of a Multiple Class Fund and purchases
of shares of the No Load Funds and Lower Load Funds, A CONTINGENT DEFERRED SALES
CHARGE OF 1% APPLIES TO PURCHASES OF $1,000,000 OR MORE THAT ARE REDEEMED WITHIN
18 MONTHS OF THE DATE OF PURCHASE. For a description of the AIM Funds
participating in this program, see "Terms and Conditions of Purchase of the AIM
Funds -- Sales Charges and Dealer Concessions." This charge will be 1% of the
lesser of the value of the shares redeemed (excluding reinvested dividends and
capital gain distributions) or the total original cost of such shares. In
determining whether a contingent deferred sales charge is payable, and the
amount of any such charge, shares not subject to the contingent deferred sales
charge are redeemed first (including shares purchased by reinvested dividends
and capital gains distributions and amounts representing increases from capital
appreciation), and then other shares are redeemed in the order of purchase. No
such charge will be imposed upon exchanges unless the shares acquired by
exchange are redeemed within 18 months of the date the shares were originally
purchased. For purposes of computing this 18-MONTH PERIOD (i) shares of any Load
Fund or AIM Cash Reserve Shares of AIM MONEY MARKET FUND which were acquired
through an exchange of shares which previously were subject to the 1% contingent
deferred sales charge will be credited with the period of time such exchanged
shares were held, and (ii) shares of any Load Fund which are subject to the 1%
contingent deferred sales charge and which were acquired through an exchange of
shares of a Lower Load Fund or a No Load Fund which previously were not subject
to the 1% contingent deferred sales charge will not be credited with the period
of time such exchanged shares were held. The charge will be waived in the
following circumstances: (1) redemptions of shares by employee benefit plans
("Plans") qualified under Sections 401 or 457 of the Code, or Plans created
under Section 403(b) of the Code and sponsored by nonprofit organizations as
defined under Section 501(c)(3) of the Code, where shares are being redeemed in
connection with employee terminations or withdrawals, and (a) the total amount
invested in a Plan is at least $1,000,000, (b) the sponsor of a Plan signs a
letter of intent to invest at least $1,000,000 in one or more of the AIM Funds,
or (c) the shares being redeemed were purchased by an employer-sponsored Plan
with at least 100 eligible employees; provided, however, that Plans created
under Section 403(b) of the Code which are sponsored by public educational
institutions shall qualify under (a), (b) or (c) above on the basis of the value
of each Plan participant's aggregate investment in the AIM Funds, and not on the
aggregate investment made by the Plan or on the number of eligible employees;
(2) redemptions of shares following the death or post-purchase disability, as
defined in Section 72(m)(7) of the Code, of a shareholder or a settlor of a
living trust; (3) redemptions of shares purchased at net asset value by private
foundations or endowment funds where the initial amount invested was at least
$1,000,000; (4) redemptions of shares purchased by an investor in amounts of
$1,000,000 or more where such investor's dealer of record, due to the nature of
the investor's account, notifies AIM Distributors prior to the time of
investment that the dealer waives the payments otherwise payable to the dealer
as described in the third paragraph under the caption "Terms and Conditions of
Purchase of the AIM Funds -- All Groups of AIM Funds"; and (5) pursuant to a
Systematic Withdrawal Plan, provided that amounts withdrawn under such plan do
not exceed on an annual basis 12% of the value of the shareholder's investment
in Class A shares at the time the shareholder elects to participate in the
Systematic Withdrawal Plan.
 
  REDEMPTIONS BY MAIL. Redemption requests must be in writing and sent to the
Transfer Agent. Upon receipt of a redemption request in proper form, payment
will be made as soon as practicable, but in any event will normally be made
within seven days after receipt. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders."
 
  Requests for redemption must include: (a) original signatures of each
registered owner exactly as the shares are registered; (b) the Fund and the
account number of shares to be redeemed; (c) share certificates, either properly
endorsed or accompanied by a duly executed stock power, for the shares to be
redeemed if such certificates have been issued and the shares are not in the
custody of the Transfer Agent; (d) signature guarantees, as described below; and
(e) any additional documents that may be required for redemption by
corporations, partnerships, trusts or other entities. The burden is on the
shareholder to inquire as to whether any additional documentation is required.
Any request not in proper form may be rejected and in such case must be renewed
in writing.
 
  In addition to these requirements, shareholders who have invested in a fund to
establish an IRA, should include the following information along with a written
request for either partial or full liquidation of fund shares: (a) a statement
as to whether or not the shareholder has attained age 59-1/2; and (b) a
statement as to whether or not the shareholder elects to have federal income tax
withheld from the proceeds of the liquidation.

  REDEMPTIONS BY TELEPHONE. Shareholders may request a redemption by telephone.
If a shareholder does not wish to allow telephone redemptions by any person in
his account, he should decline that option on the account application. The
telephone redemption feature can be used only if: (a) the redemption proceeds
are to be mailed to the address of record or transferred electronically or wired
to the pre-authorized bank account; (b) there has been no change of address of
record on the account within the preceding 30 days; (c) the shares to be
redeemed are not in certificate form; (d) the person requesting the redemption
can provide proper identification information; and (e) the proceeds of the
redemption do not exceed $50,000. Accounts in AIM Distributors' prototype
retirement plans (such as IRA and IRA/SEP) or 403(b) plans are not eligible for
the telephone redemption option. AIM Distributors has made arrangements with
certain dealers and investment advisors to accept telephone instructions for the
redemption of shares. AIM Distributors reserves the right to impose conditions
on these dealers and investment advisors, including the condition that they
enter into agreements (which contain additional conditions with respect to the
redemption of shares) with AIM Distributors. The Transfer Agent and AIM
Distributors will not be liable for any loss, expense or cost arising out of any
telephone redemption request effected in accordance with the authorization set
forth in the appropriate form if they reasonably believe such request to be gen-
                                                                       MCF-02/98
                                      A-15

uine, but may in certain cases be liable for losses due to unauthorized or
fraudulent transactions if they do not follow reasonable procedures for
verification of telephone transactions. Such reasonable procedures 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 transaction.
 
  EXPEDITED REDEMPTIONS (AIM MONEY MARKET FUND ONLY). If a redemption order is
received prior to 11:30 a.m. Eastern Time, the redemption will be effective on
that day and AIM MONEY MARKET FUND will endeavor to transmit payment on that
same business day. If the redemption order is received after 11:30 a.m. and
prior to NYSE Close, the redemption will be made at the next determined net
asset value and payment will generally be transmitted on the next business day.
 
  REDEMPTIONS BY CHECK (AIM TAX-EXEMPT CASH FUND and AIM Cash Reserve Shares of
AIM MONEY MARKET FUND). After completing the appropriate authorization form,
shareholders may use checks to effect redemptions from AIM TAX-EXEMPT CASH FUND
and the AIM Cash Reserve Shares of AIM MONEY MARKET FUND. This privilege does
not apply to retirement accounts or qualified plans. Checks may be drawn in any
amount of $250 or more. Checks drawn against insufficient shares in the account,
against shares held less than ten business days, or in amounts of less than the
applicable minimum will be returned to the payee. The payee of the check may
cash or deposit it in the same way as an ordinary bank check. When a check is
presented to the Transfer Agent for payment, the Transfer Agent will cause a
sufficient number of shares of such fund to be redeemed to cover the amount of
the check. Shareholders are entitled to dividends on the shares redeemed through
the day on which the check is presented to the Transfer Agent for payment.
 
  TIMING AND PRICING OF REDEMPTION ORDERS. Shares of the various AIM Funds
(other than AIM MONEY MARKET FUND) are redeemed at their net asset value next
computed after a request for redemption in proper form (including signature
guarantees and other required documentation for written redemptions) is received
by the Transfer Agent, except that shares that are subject to a contingent
deferred sales charge, may be subject to the imposition of deferred sales
charges that will be deducted from the redemption proceeds. See "Multiple
Distribution System" and "Contingent Deferred Sales Charge Program for Large
Purchases." Orders for the redemption of shares received in proper form prior to
NYSE Close on any business day of an AIM Fund will be confirmed at the price
determined as of the close of that day. Orders received after NYSE Close will be
confirmed at the price determined on the next business day of an AIM Fund.
Redemptions of shares of AIM MONEY MARKET FUND received prior to 12:00 noon or
NYSE Close on any business day of the Fund will be confirmed at the price next
determined. It is the responsibility of the dealer to ensure that all orders are
transmitted on a timely basis. Any resulting loss from the dealer's failure to
submit a request for redemption within the prescribed time frame will be borne
by that dealer. Telephone redemption requests must be made by NYSE Close on any
business day of an AIM Fund and will be confirmed at the price determined as of
the close of that day. No AIM Fund will accept requests which specify a
particular date for redemption or which specify any special conditions.

  Payment of the proceeds of redeemed shares is normally made within seven days
following the redemption date. However, in the event of a redemption of shares
purchased by check, the investor may be required to wait up to ten business days
before the redemption proceeds are sent. See "Terms and Conditions of Purchase
of the AIM Funds -- Timing of Purchase Orders." A charge for special handling
(such as wiring of funds or expedited delivery services) may be made by the
Transfer Agent. The right of redemption may not be suspended or the date of
payment upon redemption postponed except under unusual circumstances such as
when trading on the NYSE is restricted or suspended. Payment of the proceeds of
redemptions relating to shares for which checks sent in payment have not yet
cleared will be delayed until it is determined that the check has cleared, which
may take up to ten business days from the date that the check is received.

  SIGNATURE GUARANTEES. A signature guarantee is designed to protect the
investor, the AIM Funds, AIM Distributors, and their agents by verifying the
signature of each investor seeking to redeem, transfer, or exchange shares of an
AIM Fund. Examples of when signature guarantees are required are: (1)
redemptions by mail in excess of $50,000; (2) redemptions by mail if the
proceeds are to be paid to someone other than the name(s) in which the account
is registered; (3) written redemptions requesting proceeds to be sent to other
than the bank of record for the account; (4) redemptions requesting proceeds to
be sent to a new address or an address that has been changed within the past 30
days; (5) requests to transfer the registration of shares to another owner; (6)
telephone exchange and telephone redemption authorization forms; (7) changes in
previously designated wiring or electronic funds transfer instructions; and (8)
written redemptions or exchanges of shares previously reported as lost, whether
or not the redemption amount is under $50,000 or the proceeds are to be sent to
the address of record. These requirements may be waived or modified upon notice
to shareholders.

  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 Securities and
Exchange Commission ("SEC"), and further provided that such guarantor
institution is listed in one of the reference guides contained in the Transfer
Agent's current Signature Guarantee Standards and Procedures, such as certain
domestic banks, credit unions, securities dealers, or securities exchanges. The
Transfer Agent 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 transaction involved does not
exceed

                                                                       MCF-02/98
                                      A-16

the surety coverage amount indicated on the medallion. For information regarding
whether a particular institution or organization qualifies as an "eligible
guarantor institution," an investor should contact the Client Services
Department of AFS.
 
  REINSTATEMENT PRIVILEGE (CLASS A SHARES ONLY). Within 90 days of a redemption,
a shareholder may invest all or part of the redemption proceeds in Class A
shares of any AIM Fund at the net asset value next computed after receipt by the
Transfer Agent of the funds to be reinvested; provided, however, if the
redemption was made from Class A shares of either AIM LIMITED MATURITY TREASURY
FUND or AIM TAX-FREE INTERMEDIATE FUND, the reinvested proceeds will be subject
to the difference in sales charge between the shares redeemed and the shares the
proceeds are reinvested in. The shareholder must ask the Transfer Agent for such
privilege at the time of reinvestment. A realized gain on the redemption is
taxable, and reinvestment may alter any capital gains payable. If there has been
a loss on the redemption and shares of the same fund are repurchased, all of the
loss may not be tax deductible, depending on the timing and amount reinvested.
Under the Code, if the redemption proceeds of fund shares on which a sales
charge was paid are reinvested in (or exchanged for) shares of another AIM Fund
at a reduced sales charge within 90 days of the payment of the sales charge, the
shareholder's basis in the fund shares redeemed may not include the amount of
the sales charge paid, thereby reducing the loss or increasing the gain
recognized from the redemption; however, the shareholder's basis in the fund
shares purchased will include the sales charge. Each AIM Fund may amend, suspend
or cease offering this privilege at any time as to shares redeemed after the
date of such amendment, suspension or cessation. This privilege may only be
exercised once each year by a shareholder with respect to each AIM Fund.
 
  Shareholders who are assessed a contingent deferred sales charge in connection
with the redemption of Class A shares and who subsequently reinvest a portion or
all of the value of the redeemed shares in Class A shares of any AIM Fund within
90 days after such redemption may do so at net asset value if such privilege is
claimed at the time of reinvestment. Such reinvested proceeds will not be
subject to either a front-end sales charge at the time of reinvestment or an
additional contingent deferred sales charge upon subsequent redemption. In order
to exercise this reinvestment privilege, the shareholder must notify the
Transfer Agent of his or her intent to do so at the time of reinvestment. This
reinvestment privilege does not apply to Class B or Class C shares.
 
- --------------------------------------------------------------------------------
 
DETERMINATION OF NET ASSET VALUE
 
  The net asset value per share (or share price) of each AIM Fund is determined
as of 4:00 p.m. Eastern Time (12:00 noon Eastern Time and NYSE Close with
respect to AIM MONEY MARKET FUND), on each "business day" of a fund as
previously defined. In the event the NYSE closes early (i.e. before 4:00 p.m.
Eastern Time) on a particular day, the net asset value of an AIM Fund's share
will be determined as of the close of the NYSE on such day. For purposes of
determining net asset value per share, futures and options contracts generally
will be valued 15 minutes after the close of trading of the NYSE. The net asset
value per share is calculated by subtracting a class' liabilities from its
assets and dividing the result by the total number of class shares outstanding.
The determination of net asset value per share is made in accordance with
generally accepted accounting principles. Among other items, liabilities include
accrued expenses and dividends payable, and total assets include portfolio
securities valued at their market value, as well as income accrued but not yet
received. Securities for which market quotations are not readily available are
valued at fair value as determined in good faith by or under the supervision of
the fund's officers and in accordance with methods which are specifically
authorized by its governing Board of Directors or Trustees. Short-term
obligations with maturities of 60 days or less, and the securities held by the
Money Market Funds, are valued at amortized cost as reflecting fair value. 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.
 
  Generally, trading in foreign securities, corporate bonds, U.S. Government
securities and money market instruments is substantially completed each day at
various times prior to the close of the NYSE. The values of such securities used
in computing the net asset value of an AIM Fund's shares are determined as of
such times. Foreign currency exchange rates are also generally determined prior
to the close of the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which the
values of the securities are determined and the close of the NYSE which will not
be reflected in the computation of an AIM Fund's net asset value. If events
materially affecting the value of such securities occur during such period, then
these securities will be valued at their fair value as determined in good faith
by or under the supervision of the Board of Directors or Trustees of the
applicable AIM Fund.

                                                                       MCF-02/98

  In determining the amount of capital gains, if any, available for
distribution, net capital gains are offset against available net capital losses,
if any, carried forward from previous fiscal periods.
 
  All dividends and distributions of an AIM Fund are automatically reinvested on
the payment date in full and fractional shares of such fund, unless the
shareholder has made an alternate election as to the method of payment.
Dividends and distributions attributable to a class are reinvested in additional
shares of such class, absent an election by a shareholder to receive cash or to
have such dividends and distributions reinvested in like shares of another
Multiple Class Fund, to the extent permitted. For funds that do not declare a
dividend daily, such dividends and distributions will be reinvested at the net
asset value per share determined on the ex-dividend date. For funds that declare
a dividend daily, such dividends and distributions will be reinvested at the net
asset value per share determined on the payable date. Shareholders may elect, by
written notice to the Transfer Agent, to receive such distributions, or the
dividend portion thereof, in cash, or to invest such dividends and distributions
in shares of another fund in the AIM Funds; provided that (i) dividends and
distributions attributable to Class B shares may only be reinvested in Class B
shares, (ii) dividends and distributions attributable to Class C shares may only
be reinvested in Class C shares (iii) dividends and distributions attributable
to Class A shares may not be reinvested in Class B or Class C shares, and (iv)
dividends and distributions attributable to the AIM Cash Reserve Shares of AIM
MONEY MARKET FUND may not be reinvested in the Class A shares of that Fund or in
any Class B or Class C shares. Investors who have not previously selected such a
reinvestment option on the account application form may contact the Transfer
Agent at any time to obtain a form to authorize such reinvestments in another
AIM Fund. Such reinvestments into the AIM Funds are not subject to sales
charges, and shares so purchased are automatically credited to the account of
the shareholder.

  Dividends on Class B and Class C shares are expected to be lower than those
for Class A shares or AIM Cash Reserve Shares because of higher distribution
fees paid by Class B and Class C shares. Dividends on all shares may also be
affected by other class-specific expenses.

  Changes in the form of dividend and distribution payments may be made by the
shareholder at any time by notice to the Transfer Agent and are effective as to

the record date of such

                                                                       MCF-02/98

payment. Any dividend and distribution election remains in effect until the
Transfer Agent receives a revised written election by the shareholder.
 
  Any dividend or distribution paid by a fund which does not declare dividends
daily has the effect of reducing the net asset value per share on the
ex-dividend date by the amount of the dividend or distribution. Therefore, a
dividend or distribution declared shortly after a purchase of shares by an
investor would represent, in substance, a return of capital to the shareholder
with respect to such shares even though it would be subject to income taxes, as
discussed below.
 
TAX MATTERS
 
  Each AIM Fund has qualified and intends to qualify for treatment as a
regulated investment company under Subchapter M of the Code. As long as a fund
qualifies for this tax treatment, it is not subject to federal income taxes on
net investment income and capital gains that are distributed to shareholders.
Each fund, for purposes of determining taxable income, distribution requirements
and other requirements of Subchapter M, is treated as a separate corporation.
Therefore, no fund may offset its gains against another fund's losses and each
fund must individually comply with all of the provisions of the Code which are
applicable to its operations.
 
  TAX TREATMENT OF DISTRIBUTIONS -- GENERAL. Because each AIM Fund intends to
distribute substantially all of its net investment income and net realized
capital gains to its shareholders, it is not expected that any such fund will be
required to pay any federal income tax. Each AIM Fund also intends to meet the
distribution requirements of the Code to avoid the imposition of a
non-deductible 4% excise tax calculated as a percentage of certain undistributed
amounts of taxable ordinary income and capital gain net income. Nevertheless,
shareholders normally are subject to federal income taxes, and any applicable
state and local income taxes, on the dividends and distributions received by
them from a fund whether in the form of cash or additional shares of a fund,
except for tax-exempt dividends paid by AIM HIGH INCOME MUNICIPAL FUND, AIM
MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND OF CONNECTICUT, AIM TAX-EXEMPT
CASH FUND, and AIM TAX-FREE INTERMEDIATE FUND (the "Tax-Exempt Funds") which are
exempt from federal tax. Dividends paid by a fund (other than capital gain
distributions) may qualify for the federal 70% dividends received deduction for
corporate shareholders to the extent of the qualifying dividends received by the
fund on domestic common or preferred stock. It is not likely that dividends
received from AIM ADVISOR INTERNATIONAL VALUE FUND, AIM ADVISOR REAL ESTATE
FUND, AIM ASIAN GROWTH FUND, AIM EUROPEAN DEVELOPMENT FUND, AIM GLOBAL
AGGRESSIVE GROWTH FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL INCOME FUND, AIM HIGH
INCOME MUNICIPAL FUND, AIM HIGH YIELD FUND, AIM INCOME FUND, AIM INTERMEDIATE
GOVERNMENT FUND, AIM INTERNATIONAL EQUITY FUND, AIM LIMITED MATURITY TREASURY
FUND, AIM MONEY MARKET FUND, AIM MUNICIPAL BOND FUND, AIM TAX-EXEMPT BOND FUND
OF CONNECTICUT, AIM TAX-EXEMPT CASH FUND or AIM TAX-FREE INTERMEDIATE FUND will
qualify for this dividends received deduction. Shortly after the end of each
year, shareholders will receive information regarding the amount and federal
income tax treatment of all distributions paid during the year. Certain
dividends declared in October, November or December of a calendar year are
taxable to shareholders as though received on December 31 of that year if paid
to shareholders during January of the following calendar year. No gain or loss
will be recognized by shareholders upon the automatic conversion of Class B
shares of a Multiple Class Fund into Class A shares of such Fund. With respect
to tax-exempt shareholders, distributions from the Funds will not be subject to
federal income taxation to the extent permitted under the applicable tax-
exemption.
 
  For each redemption of a fund's shares by a non-exempt shareholder, the fund
or the securities dealer effecting the transaction is required to file an
information return with the IRS.
 
  TO AVOID BEING SUBJECT TO FEDERAL INCOME TAX WITHHOLDING AT THE RATE OF 31% ON
DIVIDENDS, DISTRIBUTIONS AND REDEMPTION PAYMENTS, SHAREHOLDERS OF A FUND MUST
FURNISH THE FUND WITH THEIR TAXPAYER IDENTIFICATION NUMBER AND CERTIFY UNDER
PENALTIES OF PERJURY THAT THE NUMBER PROVIDED IS CORRECT AND THAT THEY ARE NOT
SUBJECT TO BACKUP WITHHOLDING FOR ANY REASON.
 
  Under existing provisions of the Code, nonresident alien individuals, foreign
partnerships and foreign corporations may be subject to federal income tax
withholding at a 30% rate on ordinary income dividends and distributions (other
than exempt-interest dividends and capital gain dividends) and return of capital
distributions. Under applicable treaty law, residents of treaty countries may
qualify for a reduced rate of withholding or a withholding exemption.
 
  DISTRIBUTIONS MAY BE SUBJECT TO TREATMENT UNDER FOREIGN, STATE OR LOCAL TAX
LAWS THAT DIFFERS FROM THE FEDERAL INCOME TAX CONSEQUENCES DISCUSSED HEREIN.
ADDITIONAL INFORMATION ABOUT TAXES IS SET FORTH IN THE STATEMENT OF ADDITIONAL
INFORMATION.
 
  TAX-EXEMPT FUNDS -- SPECIAL TAX INFORMATION. Shareholders will not be required
to include the "exempt-interest" portion of dividends paid by the Tax-Exempt
Funds in their gross income for federal income tax purposes. However,
shareholders will be required to report the receipt of exempt-interest dividends
and other tax-exempt interest on their federal income tax returns. Moreover,
exempt-interest dividends from the Tax-Exempt Funds may be subject to state
income taxes, may give rise to a federal alternative minimum tax liability, may
affect the amount of social security benefits subject to federal income tax, may
affect the deductibility of interest on certain indebtedness of the shareholder,
and may have other collateral federal income tax consequences. The Tax-Exempt
Funds may invest in Municipal Securities the interest on which will constitute
an item of tax preference and which therefore could give rise to a federal
alternative minimum tax liability for shareholders, and may invest up to 20% of
their net assets in such securities and

                                                                       MCF-02/98
                                      A-19
<PAGE>   40
 
other taxable securities. For additional information concerning the alternative
minimum tax and certain collateral tax consequences of the receipt of
exempt-interest dividends, see the Statements of Additional Information
applicable to the Tax-Exempt Funds.
 
  The Tax-Exempt Funds may pay dividends to shareholders which are taxable, but
will endeavor to avoid investments which would result in taxable dividends. The
percentage of dividends which constitute exempt-interest dividends, and the
percentage thereof (if any) which constitute an item of tax preference, will be
determined annually. This percentage may differ from the actual percentages for
any particular day.
 
  To the extent that dividends are derived from taxable investments or net
realized short-term capital gains, they will constitute ordinary income for
federal income tax purposes, whether received in cash or additional shares.
Distributions of net long-term capital gains will be taxable as long-term
capital gains, whether received in cash or additional shares, and regardless of
the length of time a particular shareholder may have held his 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
Tax-Exempt Funds to pay exempt-interest dividends might be adversely affected.
 
  AIM INTERMEDIATE GOVERNMENT FUND and AIM LIMITED MATURITY TREASURY
FUND -- SPECIAL TAX INFORMATION. Certain states exempt from state income taxes
dividends paid by mutual funds out of interest on U.S. Treasury and certain
other U.S. government obligations, and investors should consult with their own
tax advisors concerning the availability of such exemption.
 
  AIM ADVISOR INTERNATIONAL VALUE FUND, AIM ASIAN GROWTH FUND, AIM EUROPEAN
DEVELOPMENT FUND, AIM INTERNATIONAL EQUITY FUND, AIM GLOBAL AGGRESSIVE GROWTH
FUND, AIM GLOBAL GROWTH FUND, AIM GLOBAL INCOME FUND AND AIM GLOBAL UTILITIES
FUND -- SPECIAL TAX INFORMATION. For taxable years in which it is eligible to do
so, each of these funds may elect to pass through to shareholders credits for
foreign taxes paid. If the fund makes such an election, a shareholder who
receives a distribution (1) will be required to include in gross income his
proportionate share of foreign taxes allocable to the distribution and (2) may
claim a credit or deduction for such share for his taxable year in which the
distribution is received, subject to the general limitations imposed on the
allowance of foreign tax credits and deductions. Shareholders should also note
that certain gains or losses attributable to fluctuations in exchange rates or
foreign currency forward contracts may increase or decrease the amount of income
of the fund available for distribution to shareholders, and should note that if
such losses exceed other income during a taxable year, the fund would not be
able to pay ordinary income dividends.

  YEAR 2000 COMPLIANCE PROJECT. In providing services to the AIM Funds, AIM
Management and its subsidiaries rely on both internal software systems as well
as external software systems provided by third parties. Many software systems in
use today are unable to distinguish between the year 2000 from the year 1900.
This defect if not cured will likely adversely affect the services that AIM
Management, its subsidiaries and other service providers provide the AIM Funds
and their shareholders.
 
  To address this issue, AIM Management and its subsidiaries, together with
independent technology consultants, are undertaking a comprehensive Year 2000
Compliance Project (the "Project"). The Project consists of three phases, namely
(i) inventorying every software application in use at AIM Management and its
subsidiaries, as well as remote, third party software systems on which AIM
Management and its subsidiaries rely, (ii) identifying those applications that
may not function properly after December 31, 1999, and (iii) correcting and
subsequently testing those applications that may not function properly after
December 31, 1999. Phases (i) and (ii) are complete and phase (iii) has
commenced. The Project is scheduled to be completed during the fourth quarter of
1998. Software applications acquired by AIM Management and its subsidiaries
after completion of the Project will be reviewed to confirm Year 2000 compliance
upon installation.
                                                                       MCF-02/98

  Applications without a certified TIN will not be accepted unless the applicant
is a nonresident alien, foreign corporation or foreign partnership and has
attached a completed IRS Form W-8.
 
  BACKUP WITHHOLDING. Each AIM Fund, and other payers, must, according to IRS
regulations, withhold 31% of redemption payments and reportable dividends
(whether paid or accrued) in the case of any shareholder who fails to provide
the Fund with a TIN and a certification that he is not subject to backup
withholding.
 
  An investor is subject to backup withholding if:
 
  (1) the investor fails to furnish a correct TIN to the Fund, or
 
  (2) the IRS notifies the Fund that the investor furnished an incorrect TIN, or
 
  (3) the investor 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), or
 
  (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 reportable
      interest, dividend, broker or barter exchange accounts opened after 1983,
      or broker accounts considered inactive during 1983.
 
  Except as explained in (5) above, other reportable payments are subject to
backup withholding only if (1) or (2) above applies.
 
  Certain payees and payments are exempt from backup withholding and information
reporting and such entities should check the box "Exempt from Backup
Withholding" on the Application. A complete listing of such exempt entities
appears in the Instructions for the Requester of Form W-9 (which can be obtained
from the IRS) and includes, among others, the following:
 
- - a corporation
- - an organization exempt from tax under Section 501(a), an individual retirement
  plan (IRA), or a custodial account under Section 403(b)(7)
- - the United States or any of its agencies or instrumentalities
- - a state, the District of Columbia, a possession of the United States, or any
  of their political subdivisions or instrumentalities
- - a foreign government or any of its political subdivisions, agencies or
  instrumentalities
- - an international organization or any of its agencies or instrumentalities
- - a foreign central bank of issue
- - a dealer in securities or commodities required to register in the U.S. or a
  possession of the U.S.
- - a futures commission merchant registered with the Commodity Futures Trading
  Commission
- - a real estate investment trust
- - an entity registered at all times during the tax year under the Investment
  Company Act of 1940
- - a common trust fund operated by a bank under Section 584(a)
- - a financial institution
- - a middleman known in the investment community as a nominee or listed in the
  most recent publication of the American Society of Corporate Secretaries,
  Inc., Nominee List
- - a trust exempt from tax under Section 664 or described in Section 4947
 
  Investors should contact the IRS if they have any questions concerning
entitlement to an exemption from backup withholding.
NOTE: Section references are to sections of the Code.
 
  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.

                                                                   MCF-02/98

<PAGE>   43
  NONRESIDENT ALIENS -- Nonresident alien individuals and foreign entities are
not subject to the backup withholding previously discussed, but must certify
their foreign status by attaching IRS Form W-8 to their application. Form W-8
remains in effect for three calendar years beginning with the calendar year in
which it is received by the Fund. Such shareholders may, however, be subject to
appropriate withholding as described in the Prospectus under "Dividends,
Distributions and Tax Matters."

  SPECIAL INFORMATION REGARDING TELEPHONE EXCHANGE PRIVILEGE. By signing the new
Account Application form, an investor appoints the Transfer Agent as his true
and lawful attorney-in-fact to surrender for redemption any and all unissued

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. The Transfer Agent and 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

he understands and agrees that the Transfer Agent and 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

and mailings of confirmations promptly after the transaction. The Transfer Agent
reserves the right to cease to act as attorney-in-fact subject to this
appointment, and AIM Distributors reserves the right to modify or terminate the
telephone exchange privilege at any time without notice. An investor may elect
not to have this privilege by marking the appropriate box on the application.
