Dear Shareholder:
 
Enclosed is a combined proxy statement and prospectus seeking your approval of a
proposed combination of AIM International Growth Fund with AIM International
Equity Fund and a proposed combination of AIM Worldwide Growth Fund with AIM
Global Growth Fund. AIM International Growth Fund and AIM Worldwide Growth Fund
(the "Acquired Funds") are investment portfolios of AIM Growth Series, a
Delaware business trust. AIM International Equity Fund and AIM Global Growth
Fund (the "Acquiring Funds") are investment portfolios of AIM International
Funds, Inc., a Maryland corporation.
 
The investment objective and policies of each Acquired Fund are similar to the
investment objective and policies of the Acquiring Fund with which it will
combine. A I M Advisors, Inc. serves as the investment adviser to the Acquired
Funds and the Acquiring Funds. As discussed in the accompanying document, the
Acquiring Funds have better performance histories and generally lower operating
expense ratios than the Acquired Funds. The Acquiring Funds are substantially
larger than the Acquired Funds and have a more stable base of assets. The
accompanying document describes the proposed transactions and compares the
investment policies, operating expenses and performance histories of the
Acquired Funds and Acquiring Funds.
 
Shareholders of AIM International Growth Fund and AIM Worldwide Growth Fund are
being asked to approve an Agreement and Plan of Reorganization by and among AIM
Growth Series, AIM International Funds, Inc. and A I M Advisors, Inc., that will
govern the reorganization of the Acquired Funds into the Acquiring Funds. After
careful consideration, the Board of Trustees of AIM Growth Series has
unanimously approved the proposals and recommends that you read the enclosed
materials carefully and then vote FOR the proposals.
 
Your vote is important. Please take a moment now to sign and return your proxy
cards in the enclosed postage paid return envelope. If we do not hear from you
after a reasonable amount of time you may receive a telephone call from our
proxy solicitor, Shareholder Communications Corporation, reminding you to vote
your shares. You may also vote your shares on the web at http://www.aimfunds.com
by following the instructions that appear on the enclosed proxy insert.
 
                                          Sincerely,
 
                                          /s/ ROBERT H GRAHAM

                            DATED: DECEMBER 28, 1998
 
     This document is being furnished in connection with a special meeting of
Shareholders of AIM INTERNATIONAL GROWTH FUND and AIM WORLDWIDE GROWTH FUND (the
"Acquired Funds"), investment portfolios of AIM Growth Series ("AGS"), a
Delaware business trust, to be held on February 10, 1999 (the "Special

"Agreement") by and among AGS, acting on behalf of the Acquired Funds, AIM
International Funds, Inc. ("AIF"), a Maryland corporation, acting on behalf of
AIM International Equity Fund and AIM Global Growth Fund (the "Acquiring
Funds"), and A I M Advisors, Inc. ("AIM Advisors"). The Agreement provides for
the combination of AIM International Growth Fund with AIM International Equity
Fund, and the combination of AIM Worldwide Growth Fund with AIM Global Growth
Fund (the "Reorganizations"). THE BOARD OF TRUSTEES OF AGS HAS UNANIMOUSLY
APPROVED THE AGREEMENT AND REORGANIZATIONS AS BEING IN THE BEST INTEREST OF THE

     Pursuant to the Agreement, all of the assets of an Acquired Fund will be
transferred to the Acquiring Fund with which it will combine, the Acquiring Fund

Class A shares of the Acquiring Fund to the Acquired Fund's Class A and Advisor
Class shareholders, and Class B shares of the Acquiring Fund to the Acquired
Fund's Class B shareholders. The value of each Acquired Fund shareholder's
account with the Acquiring Fund immediately after the Reorganization will be the
same as the value of such shareholder's account with the Acquired Fund
immediately prior to the Reorganization. The Reorganizations have been
structured as tax-free transactions. No initial sales charge will be imposed in
connection with the Reorganizations.
 
     The Acquiring Funds are series portfolios of AIF, an open-end, series
management investment company. The investment objective and policies of each
Acquiring Fund are similar to those of the Acquired Fund with which it will
combine. AIM Advisors serves as the investment adviser to the Acquired Funds and
the Acquiring Funds.
 
     AIM International Equity Fund seeks to provide long-term growth of capital
by investing in a diversified portfolio of international equity securities, the
issuers of which are considered by AIM Advisors to have strong earnings
momentum. AIM International Growth Fund seeks long-term growth of capital by
investing in equity securities of issuers domiciled in certain countries other
than the United States.

     AIM Global Growth Fund seeks to provide long-term growth of capital by
investing in a portfolio of global (i.e., U.S. and foreign) equity securities of
selected companies that are considered by AIM Advisors to have strong earnings
momentum. AIM Worldwide Growth Fund seeks long-term growth of capital by
investing primarily in equity securities of issuers domiciled anywhere in the

                                  INTRODUCTION
 
     This Proxy Statement/Prospectus is furnished in connection with the
solicitation of proxies by the Board of Trustees of AGS from the shareholders of
the Acquired Funds for use at the Special Meeting of Shareholders to be held at
11 Greenway Plaza, Suite 100, Houston, TX 77046 on February 10, 1999, at 3:00
p.m., local time (such meetings and any adjournments thereof are referred to as
the "Special Meeting").
 
     All properly executed and unrevoked proxies received in time for the
Special Meeting will be voted in accordance with the instructions contained
therein. If no instructions are given, shares represented by proxies will be
voted FOR the proposal to approve the Agreement and in accordance with
management's recommendation on other matters. The presence in person or by proxy
of one-third of the outstanding shares of beneficial interest in a class of
shares of an Acquired Fund at the Special Meeting will constitute a quorum
("Quorum") with respect to that class of shares. Approval of the Agreement by an
Acquired Fund requires the affirmative vote of a majority of the shares cast by
shareholders of each class of shares of that Acquired Fund. The Agreement may be
approved by one of the Acquired Funds and the Reorganization of that Acquired
Fund may be completed even though the Agreement is not approved by shareholders
of the other Acquired Fund. Abstentions and broker non-votes will be counted as
shares present at the Special Meeting for quorum purposes, but will not be
considered votes cast at the Special Meeting. Broker non-votes arise from a
proxy returned by a broker holding shares for a customer which indicates that
the broker has not been authorized by the customer to vote on a proposal. Any
person giving a proxy has the power to revoke it at any time prior to its
exercise by executing a superseding proxy or by submitting a notice of
revocation to the Secretary of AGS. In addition, although mere attendance at the
Special Meeting will not revoke a proxy, a shareholder present at the Special
Meeting may withdraw his proxy and vote in person. Shareholders may also
transact any other business not currently contemplated that may properly come
before the Special Meeting in the discretion of the proxies or their
substitutes.
 
     Shareholders of record as of the close of business on December 8, 1998 (the
"Record Date"), are entitled to vote at the Special Meeting. On the Record Date,
there were 15,261,454 Class A shares, 5,313,662 Class B shares and 23,759
Advisor Class shares of AIM International Growth Fund outstanding, and 5,213,433
Class A shares, 2,374,018 Class B shares and 56,859 Advisor Class shares of AIM
Worldwide Growth Fund outstanding. Each share is entitled to one vote for each
full share held, and a fractional vote for a fractional share held.
 
     AGS has engaged the services of Shareholder Communications Corporation
("SCC") to assist it in the solicitation of proxies for the Special Meeting. AGS
expects to solicit proxies principally by mail, but AGS or SCC may also solicit
proxies by telephone, facsimile, telegraph or personal interview. AGS's officers
will not receive any additional or special compensation for any such
solicitation. The cost of shareholder solicitation is anticipated to be
approximately $57,000. Each of the Acquired Funds will bear its costs and
expenses incurred in connection with the Reorganizations.
 
     AGS intends to mail this Proxy Statement/Prospectus and the accompanying
proxy on or about December 28, 1998.

                        REASONS FOR THE REORGANIZATIONS
 
BACKGROUND AND REASONS FOR THE REORGANIZATIONS
 
     AGS was organized as a Massachusetts business trust in 1985, and was
reorganized into a Delaware business trust on May 29, 1998. Prior to May 29,
1998, AGS operated under the name GT Global Growth Series. Chancellor LGT Asset
Management, Inc., an indirect subsidiary of Liechtenstein Global Trust AG
("LGT"), initially provided investment advisory services to GT Global Growth
Series.
 
     On May 29, 1998, LGT consummated a purchase agreement with AMVESCAP PLC
pursuant to which AMVESCAP PLC acquired LGT's Asset Management Division,
including Chancellor LGT Asset Management, Inc., which then changed its name to
INVESCO (NY), Inc. In connection with that transaction, the Board of Trustees
determined that it would be advisable to engage AIM Advisors to provide
investment advisory and other services to GT Global Growth Series with INVESCO
(NY), Inc. continuing to provide sub-advisory services. AIM Advisors and its
affiliates are indirect subsidiaries of AMVESCAP PLC that provide investment
advisory, marketing, administration, fund accounting and distribution services
to The AIM Family of Funds--Registered Trademark--. The shareholders of GT
Global Growth Series approved the change in service providers, which took effect
on May 29, 1998. GT Global Growth Series changed its name to AIM Growth Series
at that same time. AIM Advisors now serves as investment adviser to the
investment portfolios of AIM Growth Series and INVESCO Asset Management Ltd.
(London) serves as sub-adviser to several of the investment portfolios of AIM
Growth Series.
 
     AIM Advisors evaluated AIM International Growth Fund and AIM Worldwide
Growth Fund and recommended that AIM International Growth Fund be reorganized
into AIM International Equity Fund and that AIM Worldwide Growth Fund be
reorganized into AIM Global Growth Fund. AIM International Growth Fund and AIM
International Equity Fund have similar investment objectives and policies, as do
AIM Worldwide Growth Fund and AIM Global Growth Fund. AIM Advisors serves as
investment adviser for the Acquired Funds and the Acquiring Funds.
Reorganization of the Acquiring Funds into the Acquired Funds was recommended by
AIM Advisors because the Acquiring Funds have similar investment objectives and
policies, and have better performance records and generally lower operating
expense ratios than the Acquired Funds. The Acquiring Funds are also
substantially larger than the Acquired Funds and have a more stable base of
assets.
 
BOARD CONSIDERATIONS
 
     The Board of Trustees of AGS has determined that the Reorganizations of the
Acquired Funds are in the best interests of the shareholders of each of the
Acquired Funds, and recommends approval of the Agreement by the shareholders of
the Acquired Funds at the Special Meeting. A summary of the information that was
presented to, and considered by, the Board of Trustees in making their
determination is provided below.
 
     At a meeting of the Board of Trustees held on August 11 and 12, 1998, AIM
Advisors proposed that the Board of Trustees approve the Reorganizations of the
Acquired Funds into the Acquiring Funds. The Trustees received from AIM Advisors
written materials that described the structure and tax consequences of the
Reorganizations and contained information concerning the Acquired Funds and the
Acquiring Funds, including comparative total return and fee and expense
information, a comparison of the investment objectives of the Acquired Funds and
the Acquiring Funds, pro forma expense ratios and biographical information on
the portfolio managers of the Acquiring Funds.
 
     In considering the Reorganizations, the Board of Trustees noted that AIM
International Growth Fund and AIM International Equity Fund have similar
investment objectives and policies, as do AIM Worldwide
 
                                        2
<PAGE>   8
 
Growth Fund and AIM Global Growth Fund. The Board of Trustees also noted that
the expense ratios of the Acquired Funds are generally higher than the expense
ratios of the Acquiring Funds, as shown below.

    receive 5 stars, the next 22.5% receive 4 stars, the middle 35% receive 3

(2) Under the Lipper ranking system, the lower the percentile rank the better
    the performance.
 
The Trustees noted that if the better performance of AIM Global Growth Fund
continues it should offset the slightly higher expenses that would be incurred
by AIM Worldwide Growth Fund Advisor Class shareholders who receive AIM Global
Growth Fund Class A shares in the Reorganization.
 
     In addition, the Board of Trustees noted that no initial sales or other
charges would be imposed on any of the shares of the Acquiring Funds issued to
the shareholders of the Acquired Funds in connection with the Reorganizations.
The Board of Trustees also reviewed the principal terms of the Agreement.
Finally, the
 
                                        3
<PAGE>   9
 
Board of Trustees noted that the Acquired Funds would be provided with an
opinion of counsel that the Reorganizations would be tax-free as to each
Acquired Fund and its shareholders.
 
     At a meeting held on August 31, 1998, the Board of Trustees again
considered the Reorganizations. At that meeting, AIM Advisors noted that AIM
International Growth Fund had about $170 million in assets, compared with $2.3
billion in assets for AIM International Equity Fund. AIM Advisors further
indicated that AIM International Equity Fund's superior historic performance and
lower expense ratios make AIM International Equity Fund a potentially better
investment for shareholders than AIM International Growth Fund. The
Reorganization of AIM International Growth Fund into AIM International Equity
Fund would benefit shareholders by lowering the expense ratios for shareholders
of AIM International Growth Fund without imposing any tax consequences. The
Reorganization would result in reduced revenues for AIM Advisors, since AIM
Advisors would receive lower management fees on the assets presently held by AIM
International Growth Fund. AIM Advisors noted that the expenses incurred by AIM
International Growth Fund in connection with Reorganization would be offset by
lower management fees and total expenses after the Reorganization. AIM Advisors
indicated that Advisor Class shareholders of AIM International Growth Fund would
receive Class A shares of AIM International Equity Fund, which is the most
appropriate class available for such shares.
 
     AIM Advisors reported that AIM Worldwide Growth Fund's assets totaled about
$114 million, compared with $500 million for AIM Global Growth Fund. AIM
Advisors indicated that AIM Global Growth Fund had performed significantly
better than AIM Worldwide Growth Fund and had generally lower expense ratios.
AIM Advisors explained that the Reorganization would result in lost revenues for
AIM Advisors, since it would move shareholders on a tax-free basis to a fund
with lower advisory fees. AIM Advisors indicated that Advisor Class shareholders
of AIM Worldwide Growth Fund would receive Class A shares of AIM Global Growth
Fund, which is the most appropriate class available for such shares. AIM
Advisors noted that Advisor Class shares are estimated to have an expense
increase of 0.11% as a result of the Reorganization. The Board discussed these
matters further and agreed that the impact of the Reorganizations on
shareholders was favorable in general.
 
     At a subsequent meeting of the Board of Trustees held on September 23,
1998, based upon their evaluation of the information presented to them, the
Board of Trustees determined that the proposed Reorganizations will not dilute
the interests of the shareholders of either of the Acquired Funds and are in the
best interest of the shareholders of each of the Acquired Funds in view of the
better performance and generally lower operating expenses of the Acquiring Funds
with which they will be combined. Therefore, the Board of Trustees recommended
the approval of the Agreement by the shareholders of each Acquired Fund at a
special meeting.
 
                                    SYNOPSIS
 
THE REORGANIZATIONS
 
     The Reorganizations will result in the combination of AIM International
Growth Fund with AIM International Equity Fund and the combination of AIM
Worldwide Growth Fund with AIM Global Growth Fund. The Acquired Funds are
portfolios of AGS, a Delaware business trust. The Acquiring Funds are portfolios
of AIF, a Maryland corporation.
 
     If shareholders of an Acquired Fund approve the Agreement and other closing
conditions are satisfied, all of the assets of that Acquired Fund will be
transferred to the Acquiring Fund with which it will combine, the Acquiring Fund
will assume all of the liabilities of the Acquired Fund, and AIF will issue
Class A shares of the Acquiring Fund to the Acquired Fund's Class A and Advisor
Class shareholders, and Class B shares of the Acquiring Fund to the Acquired
Fund's Class B shareholders. The shares of an Acquiring Fund issued in a
Reorganization will have an aggregate net asset value equal to the value of the
Acquired Fund's net assets
 
                                        4
<PAGE>   10
 
transferred to the Acquiring Fund. Shareholders will not pay any initial sales
charge for shares of the Acquiring Funds received in connection with the
Reorganizations. The value of each shareholder's account with an Acquiring Fund
immediately after a Reorganization will be the same as the value of such
shareholder's account with the Acquired Fund immediately prior to the
Reorganization. A copy of the Agreement is attached as Appendix I to this Proxy
Statement/Prospectus. See "Additional Information About the Agreement" below.
 
     The Acquired Funds will receive an opinion of Ballard Spahr Andrews &
Ingersoll, LLP, to the effect that the Reorganizations will constitute tax-free
reorganizations for Federal income tax purposes. Thus, shareholders will not
have to pay Federal income taxes as a result of the Reorganizations. See
"Additional Information About the Agreement -- Federal Tax Consequences" below.
 
COMPARISON OF THE ACQUIRING FUNDS AND THE ACQUIRED FUNDS
 
  INVESTMENT OBJECTIVE AND POLICIES
 
     The investment objective and policies of each Acquiring Fund are similar to
the investment objective and policies of the Acquired Fund with which it will
combine.
 
     AIM International Equity Fund seeks to provide long-term growth of capital
by investing in a diversified portfolio of international equity securities, the
issuers of which are considered by AIM Advisors to have strong earnings
momentum. AIM International Growth Fund seeks long-term growth of capital by
investing in equity securities of issuers domiciled in certain countries other
than the United States.
 
     AIM Global Growth Fund seeks to provide long-term growth of capital by
investing in a portfolio of global (i.e., U.S. and foreign) equity securities of
selected companies that are considered by AIM Advisors to have strong earnings
momentum. AIM Worldwide Growth Fund seeks long-term growth of capital by
investing primarily in equity securities of issuers domiciled anywhere in the
world. See "Comparison of Investment Objectives and Policies" below.
 
  INVESTMENT ADVISORY SERVICES
 
     AIM Advisors serves as investment adviser, and INVESCO Asset Management
Ltd. (London) serves as sub-adviser, to the Acquired Funds. AIM Advisors also
serves as investment adviser to the Acquiring Funds. INVESCO Asset Management
Ltd. (London) does not act as sub-adviser for the Acquiring Funds, however, and
the Reorganizations will end INVESCO Asset Management Ltd. (London)'s role in
management of the Acquired Funds' assets.
 
  PERFORMANCE
 
     Set forth below are average annual total returns for the periods indicated
for each of the Acquiring Funds and the Acquired Funds. Average annual total
return figures do not take into account sales charges applicable to purchases of
Class A shares or redemptions of Class B shares of the Acquiring Funds or the
Acquired Funds. Past performance cannot guarantee comparable future results.

  SALES CHARGES
 
     No sales charges are applicable to shares of the Acquiring Funds received
in connection with the Reorganizations.
 
     The Acquiring Funds Class A shares, which will be issued to the Acquired
Funds Class A and Advisor Class shareholders pursuant to the Agreement, are sold
at net asset value plus an initial sales charge of 5.50% for AIM International
Equity Fund and 4.75% for AIM Global Growth Fund. After the Reorganizations,
current holders of Advisor Class shares of an Acquired Fund will be able to

value without imposition of an initial sales charge. The Acquiring Funds Class B
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.
 
     The AIM International Equity Fund Class A shares pay a fee in the amount of
0.30% of average daily net assets and the AIM Global Growth Fund Class A shares
pay a fee in the amount of 0.50% of average daily net assets to A I M

Funds of the same class.
 
                                  RISK FACTORS
 
     The Acquiring Funds and the Acquired Funds are subject to substantially
similar investment risks. The Acquiring Funds and the Acquired Funds invest in
securities of foreign companies, which generally involves greater risks than
investing in securities of domestic companies. The principal risks to AIM
International Equity Fund and AIM Global Growth Fund from investing in foreign
securities are described below.
 
     CURRENCY RISK. The value of an Acquiring Fund's foreign investments may be
affected by changes in currency exchange rates. The U.S. dollar value of a
foreign security generally decreases when the value of the U.S. dollar rises
against the foreign currency in which the security is denominated, and tends to
increase when the value of the U.S. dollar falls against such currency.
 
     Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg, the
Netherlands, Portugal and Spain are members of the European Union designated for
participation in the European Economic and Monetary Union (the "EMU"). The EMU
intends to establish a common European currency for participating countries
which will be known as the "euro." On January 1, 1999, the euro will be
substituted for national
                                        7
<PAGE>   13
 
currencies of the participating countries. During a transition period from
January 1, 1999 through December 31, 2001, national currencies will be defined
as denominations of the euro. Any other European country which is a member of
the European Union and satisfies the criteria for participation in the EMU may
elect to participate in the EMU and may supplement its existing currency with
the euro after January 1, 1999.
 
     The expected introduction of the euro presents unique risks and
uncertainties, including whether the payment and operational systems of banks
and other financial institutions will be ready by January 1, 1999; how
outstanding financial contracts will be treated after January 1, 1999; the
establishment of exchange rates for existing currencies and the euro; and the
creation of suitable clearing and settlement systems for the euro. These and
other factors could cause market disruptions before or after the introduction of
the euro and could adversely affect the value of securities held by an Acquiring
Fund.
 
     POLITICAL AND ECONOMIC RISK. The economies of many of the countries in
which an Acquiring Fund may invest are not as developed as the United States
economy and may be subject to significantly different forces. Political and
social instability, expropriation or confiscatory taxation, and limitations on
the removal of funds or other assets could also adversely affect the value of a
Fund's investments.
 
     REGULATORY RISK. Foreign companies 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 an Acquiring Fund may be reduced by withholding tax
at the source which would reduce dividend income payable to the Fund's
shareholders.
 
     MARKET RISK. The securities markets in many of the countries in which an
Acquiring Fund invests 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. 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. Further, the settlement period of securities transactions in foreign
markets may be longer than in domestic markets. These considerations generally
are more of a concern in developing countries. For example, the possibility of
revolution and the dependence on foreign economic assistance may be greater in
these countries than in developed countries. The management of the Acquiring
Funds seeks to mitigate the risks associated with these considerations through
diversification and active professional management.
 
     EMERGING MARKETS AND DEVELOPING COUNTRIES. Investors should also be aware
that the Acquiring Funds may invest in companies located within emerging or
developing countries. Investments in emerging markets or developing countries
involve exposure to economic structures that are generally less diverse and
mature and to political systems which can be expected to have less stability
than those of more developed countries. Such countries may have relatively
unstable governments, economies based on only a few industries, and securities
markets which trade only a small number of securities. Historical experience
indicates that emerging markets have been more volatile than the markets of more
mature economies; such markets have also from time to time provided higher rates
of return and greater risks to investors. AIM Advisors believes that these
characteristics of emerging markets can be expected to continue in the future.
In addition, throughout the countries formerly referred to as the Eastern Bloc,
the lack of a capital market structure or market-oriented economy and the
possible reversal of recent favorable economic, political and social events in
some of these countries present greater risks than those associated with more
developed market-oriented Western European countries and markets.

                COMPARISON OF INVESTMENT OBJECTIVES AND POLICIES
 
INVESTMENT OBJECTIVES OF AIM INTERNATIONAL EQUITY FUND AND AIM INTERNATIONAL
GROWTH FUND
 
     The investment objective of AIM International Equity Fund is to provide
long-term growth of capital by investing in a diversified portfolio of
international equity securities, the issuers of which are considered by AIM
Advisors to have strong earnings momentum.
 
     AIM International Growth Fund seeks long-term growth of capital by
investing primarily in equity securities of issuers domiciled in certain foreign
countries.
 
INVESTMENT POLICIES OF AIM INTERNATIONAL EQUITY FUND AND AIM INTERNATIONAL
GROWTH FUND
 
     Under normal market conditions, AIM International Equity Fund will invest
at least 70% of its total assets in marketable equity securities, including
common stock, preferred stock, depositary receipts for stock and other
securities having the characteristics of stock (such as an equity or ownership
interest in a company) of foreign companies which are listed on a recognized
foreign securities exchange or traded in a foreign over-the-counter-market. The
Fund may satisfy the foregoing requirement in part by investing in the
securities of foreign issuers which are in the form of American Depositary
Receipts ("ADRs"), European Depositary Receipts ("EDRs"), or other securities
representing underlying securities of foreign issuers. The Fund may also invest
up to 20% of its total assets in securities exchangeable for or convertible into
equity securities of foreign companies which are listed on a recognized foreign
securities exchange or traded in a foreign over-the-counter market.
 
     In managing AIM International Equity Fund, AIM Advisors seeks to apply to a
diversified portfolio of international equity securities substantially the same
investment strategy which it applies to several of its other managed portfolios
which have similar investment objectives but which invest primarily in United
States equities markets. The Fund will utilize to the extent practicable a fully
managed investment policy providing for the selection of securities which meet
certain quantitative standards determined by AIM Advisors. AIM Advisors reviews
carefully the earnings history and prospects for growth of each company
considered for investment by the Fund. It is expected that the Fund's portfolio,
when fully invested, will generally be comprised of two basic categories of
foreign companies: (1) "core" companies, which AIM Advisors considers to have
experienced consistent long-term growth in earnings and to have strong prospects
for outstanding future growth, and (2) companies that AIM Advisors believes are
currently experiencing a greater than anticipated increase in earnings.
 
     If a particular foreign company meets the quantitative standards determined
by AIM Advisors, its securities may be acquired by AIM International Equity Fund
regardless of the location of the company or the percentage of the Fund's
investments in the company's country or region. However, AIM Advisors will also
consider other factors in making investment decisions for the Fund, including
such factors as the prospects for relative economic growth among countries or
regions, economic and political conditions, currency exchange fluctuations, tax
considerations and the liquidity of a particular security.
 
     AIM Advisors may invest a portion of AIM International Equity Fund's assets
in (i) cash or high-grade short-term securities, including repurchase
agreements, commercial paper, time deposits and master notes, denominated either
in U.S. dollars or foreign currencies, (ii) U.S. government obligations or
investment grade (high quality) corporate bonds or other debt securities, and
(iii) taxable municipal securities, when such positions are deemed advisable in
light of economic or market conditions or for daily cash management purposes. In
addition, AIM Advisors may invest, for temporary defensive purposes, all or
substantially all of the Fund's assets in the securities described above. To the
extent that the Fund is invested to a significant degree in cash, high-grade
short-term securities, U.S. government obligations, investment grade (high
quality) corporate bonds or other debt securities, or taxable municipal
securities, its ability to achieve its investment objective of growth of capital
may be adversely affected. Under normal circumstances, the Fund will invest no
more than 20% of the value of its total assets in high-grade short-term
securities.
 
                                        9
<PAGE>   15
 
     Under normal market conditions, AIM International Equity Fund invests in
the securities of foreign companies located in at least four countries outside
the United States. The Fund will emphasize investment in foreign companies in
the developed countries of Western Europe (such as Germany, France, Switzerland,
the Netherlands and the United Kingdom) and the Pacific Basin (such as Japan,
Hong Kong and Australia), and the Fund may also invest in the securities of
companies located in developing countries (such as Turkey, Malaysia and Mexico)
in various regions of the world. A "developing country" is a country in the
initial stages of its industrial cycle.
 
     Investment in the equity markets of developing countries involves exposure
to securities exchanges 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 than the equity markets of
developed countries. At the present time, AIM does not intend to invest more
than 20% of AIM International Equity Fund's total assets in foreign companies
located in developing countries.
 
     AIM International Growth Fund is intended for investors seeking to
complement their U.S. equity investments with a professionally managed non-U.S.
portfolio. AIM International Growth Fund seeks its objective by investing, under
normal circumstances, at least 65% of its total assets in equity securities of
issuers domiciled in its Primary Investment Area, as described below. Equity
securities in which the Fund may invest include common stocks, preferred stocks,
convertible debt securities and warrants to acquire such securities. The Fund's
Primary Investment Area includes the following countries: Argentina, Australia,
Austria, Belgium, Brazil, Canada, Chile, Colombia, Denmark, Finland, France,
Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy,
Japan, Luxembourg, Malaysia, Mexico, the Netherlands, New Zealand, Norway,
Pakistan, Peru, the Philippines, Portugal, Singapore, South Africa, South Korea,
Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey, the United Kingdom and
Venezuela but not the United States.
 
     AIM International Growth Fund may also invest up to 35% of its total assets
in the equity securities of issuers domiciled outside of its Primary Investment
Area. Such investments may include: (a) securities of issuers in countries that
are not located in the Primary Investment Area but are linked by tradition,
economic markets, cultural similarities or geography to the countries in such
Primary Investment Area; and (b) securities of issuers located elsewhere in the
world that have operations in the Primary Investment Area or that stand to
benefit from political and economic events in the Primary Investment Area.
 
     Under normal circumstances, the assets of AIM International Growth Fund are
invested in the equity securities of issuers domiciled in at least three
different countries.
 
     AIM International Growth Fund may invest up to 35% of its total assets in
debt securities, including U.S. and foreign government securities and corporate
debt securities, Samurai and Yankee bonds, Eurobonds and Depository Receipts.
The issuers of such debt securities may or may not be domiciled in the Primary
Investment Area of the Fund. The Fund will limit its purchases of debt
securities to investment grade obligations. "Investment grade" debt refers to
those securities rated within one of the four highest ratings categories by
Moody's Investors Service, Inc. ("Moody's") or by Standard & Poor's, a division
of The McGraw-Hill Companies, Inc. ("S&P"), or, if not similarly rated by any
other nationally recognized statistical rating organization ("NRSRO"), deemed by
the Fund's sub-adviser to be of equivalent quality. Debt rated Baa by Moody's,
which is the lowest category of investment grade debt, is considered by Moody's
to have speculative characteristics.
 
     In managing AIM International Growth Fund, the sub-adviser seeks to
identify those countries and industries where economic and political factors,
including currency movements, are likely to produce above average growth rates.
The sub-adviser further attempts to identify those companies in such countries
and industries that are best positioned and managed to take advantage of these
economic and political factors. Investments are made in such markets only after
balancing the potential for growth of selected companies in each market relative
to the risks of investing in each such country.

INVESTMENT OBJECTIVES OF AIM GLOBAL GROWTH FUND AND AIM WORLDWIDE GROWTH FUND
 
     The investment objective of AIM Global Growth Fund is to provide long-term
growth of capital.
 
     AIM Worldwide Growth Fund seeks long-term growth of capital.
 
INVESTMENT POLICIES OF AIM GLOBAL GROWTH FUND AND AIM WORLDWIDE GROWTH FUND
 
     AIM Global Growth Fund seeks to achieve its objective by investing in a
portfolio of global equity securities of selected companies that are considered
by AIM Advisors to have strong earnings momentum. Current income is not an
important criterion of investment selection, and any such income should be
considered incidental.
 
     In managing AIM Global Growth Fund, AIM Advisors seeks to apply to the
diversified portfolio of equity securities the same investment strategy which it
applies to several of its other managed portfolios which have similar investment
objectives but which invest primarily in United States equities markets. The
Fund will utilize to the extent practicable a fully managed investment policy
providing for the selection of securities which meet certain quantitative
standards determined by AIM Advisors. AIM Advisors reviews carefully the
earnings history and prospects for growth of each company considered for
investment by the Fund. It is anticipated that common stocks will be the
principal form of investment of the Fund. The portfolio of the Fund is primarily
comprised of securities of two basic categories of companies: (a) "core"
companies, which AIM Advisors 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 AIM
Advisors believes are currently enjoying a dramatic increase in earnings.
 
     Under normal market conditions, AIM Global Growth Fund will invest
primarily in marketable equity securities (including common and preferred stock
and other securities having the characteristics of stock (such as an equity or
ownership interest in a company)) of companies which are listed on a recognized
securities exchange or traded in an over-the-counter market. The Fund may
satisfy the foregoing requirement in part by investing in the securities of
issuers which are in the form of ADRs, EDRs, or other securities representing
underlying securities of foreign issuers. The Fund may invest up to 20% of its
total assets in securities convertible into or exchangeable for equity
securities of foreign and domestic issuers which (except in the case of ADRs,
EDRs and other securities representing underlying securities of foreign issuers)
are listed on a recognized securities exchange or traded in an over-the-counter
market.
 
     If a particular foreign company meets the quantitative standards determined
by AIM Advisors, its securities may be acquired by AIM Global Growth Fund
regardless of the location of the company or the percentage of the Fund's
investments in the company's country or region. However, AIM Advisors will also
consider other factors in making investment decisions for the Fund, including
such factors as the prospects for relative economic growth among countries or
regions, economic and political conditions, currency exchange fluctuations, tax
considerations and the liquidity of a particular security. Under normal market
conditions, the Fund will maintain at least 20% of its total assets in U.S.
dollar denominated securities.
 
     AIM Worldwide Growth Fund seeks to achieve its objective by investing,
under normal circumstances, at least 65% of its total assets in equity
securities of issuers domiciled in its Primary Investment Area, as described
below. Equity securities in which the Fund may invest include common stocks,
preferred stocks, convertible debt securities and warrants to acquire such
securities. The Fund's Primary Investment Area includes the following countries:
Argentina, Australia, Austria, Belgium, Brazil, Canada, Chile, Colombia,
Denmark, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia,
Ireland, Israel, Italy, Japan, Luxembourg, Malaysia, Mexico, the Netherlands,
New Zealand, Norway, Pakistan, Peru, the Philippines, Portugal, Singapore, South
Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey,
United Kingdom, United States and Venezuela.
 
     AIM Worldwide Growth Fund will emphasize investment in companies in
developed countries such as the United States, the countries of Western Europe
and certain countries in the Pacific Basin (such as Japan, Hong Kong and
Australia). The Fund may also invest in the securities of companies located in
developing
 
                                       11
<PAGE>   17
 
countries (such as Turkey, Poland and Mexico) in various regions of the world. A
"developing country" is a country in the initial stages of its industrial cycle.
Under normal market conditions, the assets of the Fund will be invested in the
securities of companies located in at least four different countries, including
the United States.
 
     Under normal circumstances, the assets of AIM Worldwide Growth Fund are
invested in the equity securities of issuers domiciled in at least three
different countries, and 20% to 60% of the Fund's assets normally are invested
in the equity securities of U.S. issuers.
 
     AIM Worldwide Growth Fund may invest up to 35% of its total assets in debt
securities, including U.S. and foreign government securities and corporate debt
securities, Samurai and Yankee bonds, Eurobonds and Depository Receipts. The
Fund will not limit its purchases of debt securities to investment grade
obligations. "Investment grade" debt refers to those securities rated within one
of the four highest ratings categories by Moody's or by S&P, or, if not
similarly rated by any other NRSRO, deemed by the Sub-adviser to be of
equivalent quality. Debt rated Baa by Moody's, which is the lowest category of
investment grade debt, is considered by Moody's to have speculative
characteristics.
 
     In managing AIM Worldwide Growth Fund, the sub-adviser seeks to identify
those countries and industries where economic and political factors, including
currency movements, are likely to produce above average growth rates. The
sub-adviser further attempts to identify those companies in such countries and
industries that are best positioned and managed to take advantage of these
economic and political factors. Investments are made in such markets only after
balancing the potential for growth of selected companies in each market relative
to the risks of investing in each such country.

                   ADDITIONAL INFORMATION ABOUT THE AGREEMENT
 
TERMS OF THE REORGANIZATIONS
 
     The terms and conditions under which the Reorganizations may be consummated
are set forth in the Agreement. Significant provisions of the Agreement are
summarized below; however, this summary is qualified in its entirety by
reference to the Agreement, a copy of which is attached as Appendix I to this
Proxy Statement/Prospectus.
 
THE REORGANIZATIONS
 
     Each Acquiring Fund will acquire all of the assets of the Acquired Fund
with which it will combine in exchange for shares of the Acquiring Fund and the
assumption by the Acquiring Fund of the liabilities of the Acquired Fund.
Consummation of each Reorganization (the "Closing") is expected to occur on
February 12, 1999, at 5:00 p.m. Central Time (the "Effective Time") on the basis
of values calculated as of the close of regular trading on the NYSE on that
business day.
 
     At the Effective Time, all of the assets of AIM International Growth Fund
shall be delivered to the Custodian for the account of AIM International Equity
Fund in exchange for the assumption by AIM International Equity Fund of all of
the liabilities of any kind of AIM International Growth Fund and delivery by AIF
directly to (i) the AIM International Growth Fund Advisor Class shareholders and
Class A shareholders of a number of AIM International Equity Fund Class A shares
(including, if applicable, fractional shares rounded to the nearest thousandth)
and to (ii) the AIM International Growth Fund Class B shareholders of a number
of AIM International Equity Fund Class B shares (including, if applicable,
fractional shares rounded to the nearest thousandth), having an aggregate net
asset value equal to the net value of the assets of AIM International Growth
Fund so transferred, assigned and delivered.
 
     At the Effective Time, all of the assets of AIM Worldwide Growth Fund shall
be delivered to the Custodian for the account of AIM Global Growth Fund in
exchange for the assumption by AIM Global Growth Fund of all of the liabilities
of any kind of AIM Worldwide Growth Fund and delivery by AIF directly to (i) the
AIM Worldwide Growth Fund Advisor Class shareholders and Class A shareholders of
a number of AIM Global Growth Fund Class A shares (including, if applicable,
fractional shares rounded to the nearest thousandth) and to (ii) the AIM
Worldwide Growth Funds Class B shareholders of a number of AIM Global Growth
Fund Class B shares (including, if applicable, fractional shares rounded to the
nearest thousandth), having an aggregate net asset value equal to the net value
of the assets of AIM Worldwide Growth Fund so transferred, assigned and
delivered.
 
     Consummation of the Reorganization of AIM International Growth Fund is not
conditioned upon consummation of the Reorganization of AIM Worldwide Growth
Fund, and consummation of the Reorganization of AIM Worldwide Growth Fund is not
conditioned upon consummation of the Reorganization of AIM International Growth
Fund.
 
OTHER TERMS
 
     The Agreement may be amended without shareholder approval by mutual
agreement of AGS and AIF. If any amendment is made to the Agreement which
effects a material change to the Agreement and the Reorganizations, such change
will be submitted to the affected shareholders for their approval.
 
     Each of AGS and AIF has made representations and warranties in the
Agreement that are customary in matters such as the Reorganizations. The
obligations of AGS and AIF pursuant to the Agreement with respect to a
particular Acquired Fund or Acquiring Fund are subject to various conditions,
including the following: (a) the assets of the Acquired Fund to be acquired by
the Acquiring Fund with which it will be combined shall constitute at least 90%
of the fair market value of the net assets and at least 70% of the fair market
value of the gross assets held by each of the Acquired Funds immediately prior
to the Reorganizations; (b) AIF's Registration Statement on Form N-14 under the
Securities Act of 1933 (the "1933 Act") shall have been filed with the SEC and
such Registration Statement shall have become effective, and no stop-order
 
                                       17
<PAGE>   23
 
suspending the effectiveness of the Registration Statement shall have been
issued, and no proceeding for that purpose shall have been initiated or
threatened by the SEC (and not withdrawn or terminated); (c) the shareholders of
the Acquired Fund shall have approved the Agreement; and (d) AGS and AIF shall
have received an opinion from Ballard Spahr Andrews & Ingersoll, LLP, that the
Reorganizations will not result in the recognition of gain or loss for Federal
income tax purposes for the Acquired Fund, the Acquiring Fund or their
shareholders.
 
     The Acquired Fund and the Acquiring Funds have each agreed to bear their
own expenses in connection with the Reorganizations.
 
     The Board of Trustees of AGS may waive without shareholder approval any
default by AIF or any failure by AIF to satisfy any of the conditions to AGS's
obligations as long as such a waiver will not have a material adverse effect on
the benefits intended under the Agreement for the shareholders of the Acquired
Funds. The Agreement may be terminated and the Reorganizations may be abandoned
by either AGS or AIF at any time by mutual agreement of AGS and AIF, or by
either party in the event that the Acquired Funds shareholders do not approve
the Agreement or if the Closing does not occur on or before April 30, 1999.
 
FEDERAL TAX CONSEQUENCES
 
     The following is a general summary of the material Federal income tax
consequences of the Reorganizations and is based upon the current provisions of
the Internal Revenue Code of 1986, as amended (the "Code"), the existing
Treasury regulations thereunder, current administrative rulings of the Internal
Revenue Service ("IRS") and judicial decisions, all of which are subject to
change. The principal Federal income tax consequences that are expected to
result from the Reorganizations, under currently applicable law, are as follows:
(i) the Reorganizations will each qualify as a "reorganization" within the
meaning of Section 368(a) of the Code; (ii) no gain or loss will be recognized
by each Acquired Fund upon the transfer of its assets to an Acquiring Fund;
(iii) no gain or loss will be recognized by any shareholder of an Acquired Fund
upon the exchange of shares of an Acquired Fund solely for shares of an
Acquiring Fund; (iv) the tax basis of the shares of an Acquiring Fund to be
received by a shareholder of an Acquired Fund will be the same as the tax basis
of the shares of the Acquired Fund surrendered in exchange therefor; (v) the
holding period of the shares of an Acquiring Fund to be received by a
shareholder of an Acquired Fund will include the holding period for which such
shareholder held the shares of the Acquired Fund exchanged therefor, provided
that such shares of the Acquired Fund are capital assets in the hands of such
shareholder as of the Closing; (vi) no gain or loss will be recognized by an
Acquiring Fund on the receipt of assets of an Acquired Fund in exchange for
shares of the Acquiring Fund and the Acquiring Fund's assumption of the Acquired
Fund's liabilities; (vii) the tax basis of the assets of each Acquired Fund in
the hands of an Acquiring Fund will be the same as the tax basis of such assets
in the hands of the Acquired Fund immediately prior to the Reorganization; and
(viii) the holding period of the assets of an Acquired Fund to be received by
each Acquiring Fund will include the holding period of such assets in the hands
of the Acquired Fund immediately prior to the Reorganization.
 
     As a condition to Closing, Ballard Spahr Andrews & Ingersoll, LLP will
render a favorable opinion to AGS and AIF as to the foregoing Federal income tax
consequences of the Reorganizations, which opinion will be conditioned upon the
accuracy, as of the date of Closing, of certain representations of AGS and AIF
upon which Ballard Spahr Andrews & Ingersoll, LLP will rely in rendering its
opinion, which representations include, but are not limited to, the following
(taking into account for purposes thereof any events that are part of the plan
of reorganization): (A) there is no plan or intention by the shareholders of the
Acquired Funds to redeem a number of shares of the Acquiring Funds received in
the Reorganizations that would reduce an Acquired Fund shareholders' ownership
of Acquiring Fund shares to a number of shares having a value, as of the Closing
Date, of less than 50% of the value of all of the formerly outstanding shares of
the respective Acquired Fund as of the Closing Date; (B) following the
Reorganizations, each Acquiring Fund will continue the historic business of the
respective Acquired Fund (for this purpose "historic business" shall mean the
business most recently conducted by each Acquired Fund which was not entered
into in connection with the Reorganizations) or use a significant portion of
such Acquired Fund's historic business assets in its business; (C) at the
direction of the Acquired Funds, the Acquiring Funds will issue directly to each
Acquired Fund's shareholders pro rata the shares of the Acquiring Fund that each
respective Acquired Fund constructively
                                       18
<PAGE>   24
 
receives in the Reorganization and each Acquired Fund will distribute its other
properties (if any) to its shareholders on, or as promptly as practicable after,
the Closing; (D) the Acquiring Funds have no plan or intention to reacquire any
of their shares issued in the Reorganizations, except to the extent that the
Acquiring Funds are required by the Investment Company Act of 1940 (the "1940
Act") to redeem any of their shares presented for redemption; (E) the Acquiring
Funds do not plan or intend to sell or otherwise dispose of any of the assets of
the Acquired Funds acquired in the Reorganizations, except for dispositions made
in the ordinary course of their business or dispositions necessary to maintain
their status as a "regulated investment company" ("RIC") under the Code; (F) the
Acquiring Funds, the Acquired Funds and the shareholders of the Acquired Funds
will pay their respective expenses, if any, incurred in connection with the
Reorganizations; (G) each Acquiring Fund will acquire at least 90 percent of the
fair market value of the net assets, and at least 70% of the fair market value
of the gross assets, held by each respective Acquired Fund immediately before
the Reorganizations, including for this purpose any amounts used by each
Acquired Fund to pay its reorganization expenses and all redemptions and
distributions made by the Acquired Fund immediately before the Reorganizations
(other than redemptions pursuant to a demand of a shareholder in the ordinary
course of the Acquired Fund's business as an open-end diversified management
investment company under the 1940 Act and regular, normal dividends not in
excess of the requirements of Section 852 of the Code); and (H) the Acquiring
Funds and the Acquired Funds have each elected to be taxed as a RIC under
Section 851 of the Code and will each have qualified for the special Federal tax
treatment afforded RICs under the Code for all taxable periods (including the
last short taxable period of the Acquired Funds ending on the Closing and the
taxable year of the Acquiring Funds that includes the Closing).
 
     THE FOREGOING DESCRIPTION OF THE FEDERAL INCOME TAX CONSEQUENCES OF THE
REORGANIZATIONS IS MADE WITHOUT REGARD TO THE PARTICULAR FACTS AND CIRCUMSTANCES
OF ANY SHAREHOLDER OF THE ACQUIRED FUNDS. THE ACQUIRED FUNDS' SHAREHOLDERS ARE
URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC CONSEQUENCES TO THEM
OF THE REORGANIZATIONS, INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL,
FOREIGN AND OTHER TAX LAWS.
 
ACCOUNTING TREATMENT
 
     The Reorganizations will be accounted for on a tax-free combined basis.
Accordingly, the book cost basis to the Acquiring Funds of the assets of the
Acquired Funds will be the same as the book cost basis of such assets to the
Acquired Funds.
 
                             RIGHTS OF SHAREHOLDERS
 
     AIF is a Maryland corporation and AGS is a Delaware business trust. There
is much that is similar between the two forms of organization. For example, the
responsibilities, powers and fiduciary duties of the trustees of the AGS are
substantially the same as those of the directors of AIF.
 
     There are, however, certain differences between the two forms of
organization. The operations of AIF, as a Maryland corporation, are governed by
its Articles of Incorporation, and amendments and supplements thereto, and
applicable Maryland law. The operations of AGS, as a Delaware business trust,
are governed by its Agreement and Declaration of Trust, as amended (the
"Declaration of Trust") and Delaware law.
 
LIABILITY OF SHAREHOLDERS
 
     The Delaware Business Trust Act provides that shareholders of a Delaware
business trust shall be entitled to the same limitations of liability extended
to shareholders of private for-profit corporations. There is, however, a remote
possibility that, under certain circumstances, shareholders of a Delaware
business trust might be held personally liable for the trust's obligations to
the extent the courts of another state that does not recognize such limited
liability were to apply the laws of such state to a controversy involving such
obligations. The AGS Declaration of Trust provides that shareholders of the
Acquired Funds shall not be subject to any personal liability for acts or
obligations of the Acquired Funds and that every written agreement, obligation
or other undertaking made or issued by the Acquired Funds shall contain a
provision to the effect that shareholders are not personally liable thereunder.
In addition, the Declaration of Trust provides for indemnification out of the
Acquired Funds' property for any shareholder held personally liable solely by
reason
                                       19
<PAGE>   25
 
of his or her being or having been a shareholder. Therefore, the risk of any
shareholder incurring financial loss beyond his investment due to shareholder
liability is limited to circumstances in which the Acquired Funds themselves are
unable to meet their obligations and the express disclaimer of shareholder
liabilities is determined not to be effective. Given the nature of the assets
and operations of the Acquired Funds, the possibility of the Acquired Funds
being unable to meet their obligations is considered remote, and even if a claim
were brought against the Funds and a court determined that shareholders were
personally liable, it would likely not impose a material obligation on a
shareholder.
 
     Shareholders of a Maryland corporation generally do not have personal
liability for the corporation's obligations, except that a shareholder may be
liable to the extent that he receives any distribution which exceeds the amount
which he could properly receive under Maryland law or where such liability is
necessary to prevent fraud.
 
ELECTION OF DIRECTORS/TRUSTEES; TERMS
 
     The shareholders of AGS have elected the trustees of AGS. Such trustees
serve for the life of AGS, subject to the earlier death, incapacitation,
resignation, retirement or removal (see below). Shareholders may elect
successors to such Trustees only at annual or special meetings of shareholders.
 
     The shareholders of AIF have elected the directors of AIF. Each director
serves until a successor is elected, subject to earlier death, incapacitation,
resignation, retirement or removal (see below). Shareholders may elect
successors to such directors only at annual or special meetings of shareholders.
 
REMOVAL OF DIRECTORS/TRUSTEES
 
     A trustee of AGS may be removed at any time by vote of at least two-thirds
of the trustees or by vote of two-thirds of the outstanding shares of AGS. The
Declaration of Trust provides that vacancies may be filled by appointment by the
remaining trustees.
 
     A director of AIF may be removed by the affirmative vote of a majority of
the Board of Directors, a committee of the Board of Directors appointed for such
purpose, or the holders of a majority of the outstanding shares of AIF.
 
MEETINGS OF SHAREHOLDERS
 
     AGS is not required to hold annual meetings of shareholders unless required
by the 1940 Act and does not intend to do so. The By-Laws of AGS provide that a
majority of the Trustees may call special meetings of shareholders and the
Trustees shall call a special meeting of the shareholders upon written request
of the holders of not less than 10% of the Acquired Funds' shares. Special
meetings may be called for the purpose of electing trustees or for any other
action requiring shareholder approval, or for any matter deemed by the trustees
to be necessary or desirable.
 
     AIF is not required to hold annual meetings of shareholders and does not
intend to do so unless required by the 1940 Act. AIF's Bylaws provide that a
special meeting of shareholders may be called by the President, Secretary, a
majority of the Board of Directors or holders of shares entitled to cast at
least 10% of the votes entitled to be cast at the special meeting. Requests for
special meetings must, among other things, state the purpose of such meeting and
the matters to be voted upon. No special meeting may be called to consider any
matter previously voted upon at a special meeting called by the shareholders
during the preceding twelve months, unless requested by a majority of all shares
entitled to vote at such meeting.
 
LIABILITY OF DIRECTORS/TRUSTEES AND OFFICERS; INDEMNIFICATION
 
     Delaware law provides that trustees of a business trust shall not be liable
to the business trust or its shareholders for acting in good faith reliance on
the provisions of its governing instrument and that the trustee's liabilities
may be expanded or restricted by such instrument. Under the AGS Declaration of
Trust, the trustees and officers of AGS are not liable for any act or omission
or any conduct whatsoever in their capacity as trustees, except for liability to
the trust or shareholders due to willful misfeasance, bad faith, gross
                                       20
<PAGE>   26
 
negligence or reckless disregard of the duties involved in the conduct of the
office of trustee. Delaware law allows a business trust to indemnify and hold
harmless any trustee or other person against any and all claims and demands. The
AGS Declaration of Trust require the indemnification of its trustees and
officers to the fullest extent permitted by Delaware law, except with respect to
any matter in which it has been determined that such director or officer acted
with willful misfeasance, bad faith, gross negligence or reckless disregard of
his or her duties.
 
     Maryland law permits a corporation to eliminate liability of its directors
and officers to the corporation or its stockholders, except for liability
arising from receipt of an improper benefit or profit and from active and
deliberate dishonesty. AIF's Articles of Incorporation eliminate director and
officer liability to the fullest extent permitted under Maryland law. Under
Maryland law, indemnification of a corporation's directors and officers is
mandatory if a director or officer has been successful on the merits or
otherwise in the defense of certain proceedings. Maryland law permits
indemnification for other matters unless it is established that the act or
omission giving rise to the proceeding was committed in bad faith, a result of
active and deliberate dishonesty, or one in which a director or officer actually
received an improper benefit.
 
TERMINATION
 
     AGS or any series or class of shares of beneficial interest in AGS may be
terminated by a majority shareholder vote of AGS or the affected series or
class, respectively, or if there are fewer than 100 shareholders of record of
AGS or of such terminating series or class, the trustees pursuant to written
notice to the shares of AGS or the affected series or class.
 
     Maryland law provides that AIF may be dissolved by the vote of a majority
of the Board of Directors and two-thirds of the shares entitled to vote on the
dissolution.
 
VOTING RIGHTS OF SHAREHOLDERS
 
     The AGS Declaration of Trust grants shareholders power to vote only with
respect to the following: (i) election of trustees; (ii) removal of trustees,
(iii) approval of investment advisory contracts, as required by the 1940 Act;
(iv) termination of AGS or a series of class of its shares of beneficial
interest, (v) amendment of the Declaration of Trust, (vi) sale of all or
substantially all of the assets of AGS or one of its investment portfolios,
(vii) merger or consolidation of AGS or any of its investment portfolios, with
certain exceptions, and (viii) approval of such additional matters as may be
required by law or as the trustees, in their sole discretion, shall determine.
 
     Shareholders of a Maryland corporation such as AIF are entitled to vote on,
among other things, those matters which effect fundamental changes in the
corporate structure (such as a merger, consolidation or sale of substantially
all of the assets of the corporation) as provided by Maryland corporation law.
 
DISSENTERS' RIGHTS
 
     Neither Delaware law nor the Declaration of Trust confers upon AGS
shareholders appraisal or dissenters' rights.
 
     Under Maryland law, AIF's shareholders may not demand the fair value of
their shares from the successor company in a transaction involving the transfer
of the Acquiring Funds' assets, and are bound by the terms of the transaction.
 
AMENDMENTS TO ORGANIZATION DOCUMENTS
 
     Consistent with Delaware law, the Board of Trustees of AGS may, without
shareholder approval, amend the Declaration of Trust at any time, except that no
amendment may be made which reduces the indemnification provided to shareholders
or former shareholders or which changes the preferences, voting powers, rights,
and privileges of outstanding shares in a manner materially adverse to the
shareholders of such shares, without approval of the affected shareholders. The
trustees shall have the power to alter, amend or repeal the Bylaws of AGS or
adopt new Bylaws at any time.
                                       21
<PAGE>   27
 
     Consistent with Maryland law, AIF reserves the right to amend, alter,
change or repeal any provision contained in their Articles of Incorporation in
the manner now or hereafter prescribed by statute, including any amendment that
alters the contract rights, as expressly set forth in the Articles of
Incorporation, of any outstanding stock, and all rights conferred on
shareholders are granted subject to this reservation. The Board of Directors of
AIF may approve amendments to the Articles of Incorporation to classify or
reclassify unissued shares of a class of stock without shareholder approval.
Other amendments to the AIF Articles of Incorporation may be adopted if approved
by a vote of a majority of the shares at any meeting at which a quorum is
present. The AIF Bylaws provide that the Bylaws may be amended at any regular
meeting or special meeting of the stockholders provided that notice of such
amendment is contained in the notice of the special meeting. Except as to any
particular Bylaw which is specified as not subject to amendment by the Board of
Directors, the Bylaws may be also amended by the affirmative vote of a majority
of the Board of Directors at any regular or special meetings of the Board.

<PAGE>   39
 
     (b) If, on the Closing Date, an Acquired Fund is unable to make delivery in
the manner contemplated by Section 2.4(a) of securities held by the Acquired
Fund for the reason that any of such securities purchased prior to the Closing
Date have not yet been delivered to the Acquired Fund or its broker, then AIM
International shall waive the delivery requirements of Section 2.4(a) with
respect to said undelivered securities if the Acquired Fund has delivered to the
Custodian by or on the Closing Date, and with respect to said undelivered
securities, executed copies of an agreement of assignment and escrow agreement
and due bills executed on behalf of said broker or brokers, together with such
other documents as may be required by AIM International or the Custodian,
including brokers' confirmation slips.
 
     SECTION 2.5  Termination of Series. As soon as reasonably practicable after
the Closing Date, the status of each Acquired Fund as designated series of
shares of AIM Growth shall be terminated; provided, however, that the

not have been consummated.
 
     SECTION 2.6  Issuance of Acquiring Fund Shares. At the Effective Time, each
Acquired Fund Shareholder of record as of the close of regular trading on the
NYSE on the Closing Date holding such Acquired Fund Class A shares or Advisor
Class shares shall be issued that number of full and fractional Class A shares
of the Acquiring Fund with which it will combine having a net asset value equal
to the net asset value of such Acquired Fund Class A shares or Advisor Class
shares held by such Acquired Fund Shareholder on the Closing Date, and each
Acquired Fund Shareholder of record as of the Closing Date holding such Acquired
Fund Class B shares shall be issued that number of full and fractional Class B
shares of the Acquiring Fund with which it will combine having a net asset value
equal to the net asset value of such Acquired Fund Class B Shares held by such
Acquired Fund Shareholder on the Closing Date. All issued and outstanding shares
of beneficial interest in each Acquired Fund shall thereupon be canceled on the
books of AIM Growth. AIM Growth shall provide instructions to the transfer agent
of AIM International with respect to the Acquiring Fund Class A Shares and
Acquiring Fund Class B Shares to be issued to Acquired Fund Shareholders. AIM
International shall have no obligation to inquire as to the validity, propriety
or correctness of any such instruction, but shall, in each case, assume that
such instruction is valid, proper and correct. AIM International shall record on
its books the ownership of Acquiring Fund Class A and Acquiring Fund Class B
Shares by Acquired Fund Shareholders and shall forward a confirmation of such
ownership to the Acquired Fund Shareholders. No redemption or repurchase of such
shares credited to former Acquired Fund Shareholders in respect of the Acquired
Fund shares represented by unsurrendered shares certificates shall be permitted
until such certificates have been surrendered to AIM International for
cancellation, or if such certificates are lost or misplaced, until lost
certificate affidavits have been executed and delivered to AIM International.
 
     SECTION 2.7  Investment Securities. On or prior to the Closing Date, AIM
Growth shall deliver a list setting forth the securities each Acquired Fund then
owns together with the respective Federal income tax bases thereof. AIM Growth
shall provide to AIM International on or before the Closing Date, detailed tax
basis accounting records for each security to be transferred to it pursuant to
this Agreement. Such records shall be prepared in accordance with the
requirements for specific identification tax lot accounting and clearly reflect
the bases used for determination of gain and loss realized on the sale of any
security transferred to an Acquiring Fund hereunder. Such records shall be made
available by AIM Growth prior to the Closing Date for inspection by the
Treasurer (or his designee) or the auditors of AIM International upon reasonable
request.
 
     SECTION 2.8  Liabilities. Each Acquired Fund shall use reasonable best
efforts to discharge all of their known liabilities, so far as may be possible,
prior to the Closing Date.

                                   ARTICLE 3
 
                  REPRESENTATIONS AND WARRANTIES OF AIM GROWTH
 
     AIM Growth, on behalf of the Acquired Funds, represents and warrants to AIM
International that:
 
     SECTION 3.1  Organization; Authority. AIM Growth is duly organized, validly
existing and in good standing under the Delaware Business Trust Act, with all
requisite trust power and authority to enter into this Agreement and perform its
obligations hereunder.
 
     SECTION 3.2  Registration and Regulation of AIM Growth. AIM Growth is duly
registered with the SEC as an investment company under the Investment Company
Act and all Acquired Fund Shares which have been or are being offered for sale
have been duly registered under the Securities Act and have been duly
registered, qualified or are exempt from registration or qualification under the
securities laws of each state or other jurisdiction in which such shares have
been or are being offered for sale, and no action has been taken by AIM Growth
to revoke or rescind any such registration or qualification. Each Acquired Fund
is in compliance in all material respects with all applicable laws, rules and
regulations, including, without limitation, the Investment Company Act, the
Securities Act, the Exchange Act and all applicable state securities laws. Each
Acquired Fund is in compliance in all material respects with the investment
policies and restrictions applicable to it set forth in the AIM Growth
Registration Statement currently in effect. The value of the net assets of each
Acquired Fund is determined using portfolio valuation methods that comply in all
material respects with the requirements of the Investment Company Act and the
policies of such Acquired Fund and all purchases and redemptions of Acquired
Fund Shares have been effected at the net asset value per share calculated in
such manner.
 
     SECTION 3.3  Financial Statements. The books of account and related records
of each Acquired Fund fairly reflect in reasonable detail its assets,
liabilities and transactions in accordance with generally accepted accounting
principles applied on a consistent basis. The audited financial statements for
the fiscal year ended December 31, 1997, and the unaudited financial statements
for the six month period ended June 30, 1998, of each Acquired Fund previously
delivered to AIM International (the "Acquired Fund Financial Statements")
present fairly in all material respects the financial position of such Acquired
Fund as at the dates indicated and the results of operations and changes in net
assets for the periods then ended in accordance with generally accepted
accounting principles applied on a consistent basis for the periods then ended.
 
     SECTION 3.4  No Material Adverse Changes; Contingent Liabilities. Since
June 30, 1998, no material adverse change has occurred in the financial
condition, results of operations, business, assets or liabilities of an Acquired
Fund or the status of an Acquired Fund as a regulated investment company under
the Code, other than changes resulting from any change in general conditions in
the financial or securities markets or the performance of any investments made
by an Acquired Fund or occurring in the ordinary course of business of the
Acquired Fund or AIM Growth. There are no contingent liabilities of an Acquired
Fund not disclosed in the Acquired Fund Financial Statements which are required
to be disclosed in accordance with generally accepted accounting principles.
 
     SECTION 3.5  Acquired Fund Shares; Liabilities; Business Operations.
 
     (a) The Acquired Fund Shares have been duly authorized and validly issued
and are fully paid and non-assessable.
 
     (b) There is no plan or intention by the shareholders of an Acquired Fund
who own five percent (5%) or more of such Acquired Fund Shares, and to the
knowledge of AIM Growth's management the remaining shareholders of such Acquired
Fund have no present plan or intention, of selling, exchanging, redeeming or
otherwise disposing of a number of the Acquiring Fund Shares received by them in
connection with a Reorganization that would reduce such Acquired Fund
Shareholder's ownership of Acquiring Fund Shares to a number of shares having a
value, as of the Closing Date, of less than fifty percent (50%) of the value of
all of the formerly outstanding shares of such Acquired Fund as of the same
date. For purposes of this representation, Acquired Fund Shares exchanged for
cash or other property or exchanged for cash in lieu of fractional shares of the
Acquiring Fund will be treated as outstanding Acquired Fund Shares on the date
of the
                                        6
<PAGE>   41
 
Reorganization. Moreover, Acquired Fund Shares and Acquiring Fund Shares held by
Acquired Fund Shareholders and otherwise sold, redeemed or disposed of prior or
subsequent to the Reorganization will be considered in making this
representation, except for Acquired Fund Shares or Acquiring Fund Shares which
have been, or will be, redeemed by an Acquired Fund or an Acquiring Fund in the
ordinary course of its business as a series of an open-end, management
investment company under the Investment Company Act.
 
     (c) At the time of its Reorganization, an Acquired Fund shall not have
outstanding any warrants, options, convertible securities or any other type of
right pursuant to which any Person could acquire Acquired Fund Shares, except
for the right of investors to acquire such Acquired Fund Shares at net asset
value in the normal course of its business as a series of an open-end management
investment company operating under the Investment Company Act.
 
     (d) From the date it commenced operations and ending on the Closing Date,
each Acquired Fund will have conducted its historic business within the meaning
of Section 1.368-1(d)(2) of the Income Tax Regulations under the Code in a
substantially unchanged manner. In anticipation of its Reorganization, an
Acquired Fund will not dispose of assets that, in the aggregate, will result in
less than fifty percent (50%) of its historic business assets (within the
meaning of Section 1.368-1(d) of those regulations) being transferred to the
Acquiring Fund.
 
     (e) AIM Growth does not have, and has not had during the six (6) months
prior to the date of this Agreement, any employees, and shall not hire any
employees from and after the date of this Agreement through the Closing Date.

     SECTION 3.10  Permits. AIM Growth has in full force and effect all
approvals, consents, authorizations, certificates, filings, franchises,
licenses, notices, permits and rights of Governmental Authorities (collectively,
"Permits") necessary for it to conduct its business as presently conducted as it

AIM Growth there are no proceedings relating to the suspension, revocation or

expected, individually or in the aggregate, to have a Material Adverse Effect.
 
     SECTION 3.11  No Actions, Suits or Proceedings.
 
     (a) There is no pending action, litigation or proceeding, nor, to the
knowledge of AIM Growth, has any litigation been overtly threatened in writing
or, if probable of assertion, orally, against AIM Growth before any Governmental
Authority which questions the validity or legality of this Agreement or of the
actions contemplated hereby or which seeks to prevent the consummation of the
transactions contemplated hereby, including the Reorganization.
 
     (b) There are no judicial, administrative or arbitration actions, suits, or
proceedings instituted or pending or, to the knowledge of AIM Growth, threatened
in writing or, if probable of assertion, orally, against AIM Growth affecting
any property, asset, interest or right of an Acquired Fund, that could

exceptions or orders that were entered by, filed with or issued by Governmental

affecting in any significant respect the conduct of such business. AIM Growth is
not, and has not been to the knowledge of AIM Growth, the target of any
investigation by the SEC or any state securities administrator with respect to
its conduct of the business of an Acquired Fund.
 
     SECTION 3.12  Contracts. AIM Growth is not in default under any contract,
agreement, commitment, arrangement, lease, insurance policy or other instrument
to which it is a party and which involves or affects the assets of an Acquired
Fund, by which the assets, business, or operations of an Acquired Fund may be

Acquired Fund receives benefits, and which default could reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect, and, to the
knowledge of AIM Growth there has not occurred any event that, with the lapse of
time or the giving of notice or both, would constitute such a default.
 
     SECTION 3.13  Properties and Assets. Each Acquired Fund has good and
marketable title to all properties and assets reflected in the Acquired Fund
Financial Statements as owned by it, free and clear of all Liens, except as
described in the Acquired Fund Financial Statements.
 
     SECTION 3.14  Taxes.
 
     (a) Each Acquired Fund has elected to be a regulated investment company
under Subchapter M of the Code. Each Acquired Fund has qualified as such for
each taxable year since inception and that has ended prior to the Closing Date
and will have satisfied the requirements of Part I of Subchapter M of the Code
to maintain such qualification for the period beginning on the first day of its
current taxable year and ending on the Closing Date. Each Acquired Fund has no
earnings and profits accumulated in any taxable year in which the provisions of
Subchapter M of the Code did not apply to it. In order to (i) insure continued
qualification of each Acquired Fund as a "regulated investment company" for tax
purposes and (ii) eliminate any tax liability of an Acquired Fund arising by
reason of undistributed investment company taxable income or net capital gain,
AIM Growth will declare on or prior to the Closing Date to the shareholders of
each Acquired Fund a dividend or dividends that, together with all previous such
dividends, shall have the effect of distributing
                                        8
<PAGE>   43
 
(A) all of such Acquired Fund's investment company taxable income (determined
without regard to any deductions for dividends paid) for the taxable year ended
December 31, 1998 and for the short taxable year beginning on January 1, 1999
and ending on the Closing Date and (B) all of such Acquired Fund's net capital
gain reorganized in its taxable year ended December 31, 1998 and in such short
taxable year (after reduction for any capital loss carryover).
 
     (b) Each Acquired Fund has timely filed all Returns required to be filed by
it and all Taxes with respect thereto have been paid, except where the failure
so to file or so to pay, would not reasonably be expected, individually or in
the aggregate, to have a Material Adverse Effect. Adequate provision has been
made in the Acquired Fund Financial Statements for all Taxes in respect of all
periods ended on or before the date of such financial statements, except where
the failure to make such provisions would not reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect. No
deficiencies for any Taxes have been proposed, assessed or asserted in writing
by any taxing authority against either Acquired Fund, and no deficiency has been
proposed, assessed or asserted, in writing, where such deficiency would
reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect. No waivers of the time to assess any such Taxes are outstanding
nor are any written requests for such waivers pending and no Returns of either
Acquired Fund are currently being or have been audited with respect to income
taxes or other Taxes by any Federal, state, local or foreign Tax authority.
 
     (c) To the best knowledge of AIM Growth, the fiscal year of each Acquired
Fund has not been changed for tax purposes since the date on which it commenced
operations.
 
     SECTION 3.15  Benefit and Employment Obligations. On or prior to the
Closing Date, an Acquired Fund will have no obligation to provide any
post-retirement or post-employment benefit to any Person, including but not
limited to under any Benefit Plan, and have no obligation to provide unfunded
deferred compensation or other unfunded or self-funded benefits to any Person.
 
     SECTION 3.16  Brokers. No broker, finder or similar intermediary has acted
for or on behalf of AIM Growth in connection with this Agreement or the
transactions contemplated hereby, and no broker, finder, agent or similar
intermediary is entitled to any broker's, finder's or similar fee or other
commission in connection therewith based on any agreement, arrangement or
understanding with AIM Growth or any action taken by it.
 
     SECTION 3.17  Voting Requirements. The vote of a majority of each class of
shares of an Acquired Fund cast at a meeting at which a quorum is present (the
"Required Shareholder Vote") is the only vote of the holders of any class or
series of shares of beneficial interest in an Acquired Fund necessary to approve
this Agreement and the Reorganization of such Acquired Fund contemplated by this
Agreement.
 
     SECTION 3.18  State Takeover Statutes. No state takeover statute or similar
statute or regulation applies or purports to apply to the Reorganizations, this
Agreement or any of the transactions contemplated by this Agreement.
 
     SECTION 3.19  Books and Records. The books and records of AIM Growth
relating to each Acquired Fund, reflecting, among other things, the purchase and
sale of Acquired Fund Shares, the number of issued and outstanding shares owned
by each Acquired Fund Shareholder and the state or other jurisdiction in which
such shares were offered and sold, are complete and accurate in all material
respects.
 
     SECTION 3.20  Prospectus and Statement of Additional Information. The
current prospectus and statement of additional information for each Acquired
Fund as of the date on which they were issued did not contain, and as
supplemented by any supplement thereto dated prior to or on the Closing Date do
not contain, any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading.

acquired for the purpose of any distribution thereof, other than in accordance
with the terms of this Agreement.

Reorganization, or which the assets of the Acquired Fund
                                        9
<PAGE>   44
 
to be transferred in the Reorganizations are subject, were incurred by such
Acquired Fund in the ordinary course of its business. The fair market value of
the assets of each Acquired Fund to be transferred to an Acquiring Fund in a
Reorganization will equal or exceed the sum of the liabilities to be assumed by
such Acquiring Fund plus the amount of liabilities, if any, to which such
transferred assets will be subject.
 
     SECTION 3.23  Value of Shares. The fair market value of the Acquiring Fund
Class A Shares received by Acquired Fund Shareholders in each Reorganization
will be approximately equal to the fair market value of the Acquired Fund Class
A shares and the Acquired Fund Advisor Class shares constructively surrendered
in exchange therefor, and the fair market value of the Acquiring Fund Class B
Shares received by Acquired Fund Shareholders in each Reorganization will be
approximately equal to the fair market value of the Acquired Fund Class B shares
constructively surrendered in exchange therefor.
 
     SECTION 3.24  Shareholder Expenses. The Acquired Fund Shareholders will pay
their own expenses, if any, incurred in connection with the Reorganizations.
 
     SECTION 3.25  Intercompany Indebtedness. There is no intercompany
indebtedness between AIM Growth and AIM International that was issued or
acquired, or will be settled, at a discount.

for the six month period ended June 30, 1998, of each Acquiring Fund previously
delivered to AIM Growth (the "Acquiring Fund Financial Statements") present
fairly in all material respects the financial position of such Acquiring Fund as
at the dates indicated and the results of operations and changes in net assets
for the periods then ended in accordance with generally accepted accounting
principles applied on a consistent basis for the periods then ended.
 
     SECTION 4.4  No Material Adverse Changes; Contingent Liabilities. Since
June 30, 1998, no material adverse change has occurred in the financial
condition, results of operations, business, assets or liabilities of an
Acquiring Fund or the status of an Acquiring Fund as a regulated investment
company under the Code, other than changes resulting from any change in general
conditions in the financial or securities markets or the performance of any
investments made by an Acquiring Fund or occurring in the ordinary course of
business of the Acquiring Fund or AIM International. There are no contingent
liabilities of an Acquiring Fund not disclosed in the Acquiring Fund Financial
Statements which are required to be disclosed in accordance with generally
accepted accounting principles.

under the Code.
 
     (d) Following the Reorganization, each Acquiring Fund will continue the

the assets of each respective Acquired Fund are subject) will be issued in
exchange for the assets of an Acquired Fund acquired by an Acquiring Fund in

                         Supplement dated July 1, 1998
                   to the Prospectus dated February 20, 1998
 
The third sentence in the second paragraph under the caption "HEDGING STRATEGIES
AND OTHER INVESTMENT TECHNIQUES -- Options" on page 10 is deleted and replaced
in its entirety by the following:
 
     "A put option is 'covered' if the Fund segregates liquid assets with a
     value equal to the exercise price of the put option."
 
The following paragraphs are inserted as a new item under "HEDGING STRATEGIES
AND OTHER INVESTMENT TECHNIQUES," after "Investment in Other Investment
Companies" on page 12 of the prospectus:
 
     "REAL ESTATE INVESTMENT TRUSTS ("REITS"). The Fund may invest in equity
     and/or debt securities issued by REITs. Such investments will not exceed 5%
     of the total assets of the Fund.
 
     REITs are trusts which sell equity or debt securities to investors and use
     the proceeds to invest in real estate or interests therein. A REIT may
     focus on particular projects, such as apartment complexes, or geographic
     regions, such as the Southeastern United States, or both.
 
     To the extent that the Fund has the ability to invest in REITs, the Fund
     could conceivably own real estate directly as a result of a default on the
     securities it owns. The Fund, therefore, may be subject to certain risks
     associated with the direct ownership of real estate including difficulties
     in valuing and trading real estate, declines in the value of real estate,
     risks related to general and local economic condition, adverse change in
     the climate for real estate, increases in property taxes and operating
     expense, changes in zoning laws, casualty or condemnation losses,
     limitations on rents, changes in neighborhood values, the appeal of
     properties to tenants, and increases in interest rates.
 
     In addition to the risks described above, equity REITs may be affected by
     any changes in the value of the underlying property owned by the trusts,
     while mortgage REITs may be affected by the quality of any credit extended.
     Equity and mortgage REITs are dependent upon management skill, are not
     diversified, and are therefore subject to the risk of financing single or a
     limited number of projects. Such trusts are also subject to heavy cash flow
     dependency, defaults by borrowers, self-liquidation, and the possibility of
     failing to maintain exemption from the 1940 Act. Changes in interest rates
     may also affect the value of debt securities held by a Fund. By investing
     in REITs indirectly through the Fund, a shareholder will bear not only
     his/her proportionate share of the expenses of the Fund, but also,
     indirectly, similar expenses of the REITs."
 
The following paragraphs should be inserted under the heading of "RISK
FACTORS -- Currency Risk" on page 12:
 
     "Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg,
     the Netherlands, Portugal, and Spain are members of the European Economic
     and Monetary Union (the "EEMU"). The EEMU intends to establish a common
     European currency for participating countries which will be known as the
     "euro." It is anticipated that each participating country will supplement
     its existing currency with the euro on January 1, 1999, and will replace
     its existing currency with the euro on July 1, 2002. Any other European
     country which is a member of the EEMU may elect to participate in the EEMU
     and may supplement its existing currency with the euro after January 1,
     1999.
 
     The expected introduction of the euro presents unique risks and
     uncertainties, including whether the payment and operational systems of
     banks and other financial institutions will be ready by January 1, 1999;
     how outstanding financial contracts will be treated after January 1, 1999;
     the establishment of exchange rates for existing currencies and the euro;
     and the creation of suitable clearing and settlement systems for the euro.
     These and other factors could cause market disruptions before or after the
     introduction of the euro and could adversely affect the value of securities
     held by the Fund."

                                    SUMMARY
- --------------------------------------------------------------------------------
 
  THE FUND. AIM International Funds, Inc. (the "Company") is a Maryland
corporation organized as an open-end, series, management investment company.
Currently the Company offers six separate series portfolios. This Prospectus
relates to AIM INTERNATIONAL EQUITY FUND (the "Fund"). The Company also offers
other classes of shares in five other investment portfolios, AIM ASIAN GROWTH
FUND ("ASIAN FUND"), AIM EUROPEAN DEVELOPMENT FUND ("EUROPEAN FUND"), AIM GLOBAL
AGGRESSIVE GROWTH FUND ("AGGRESSIVE GROWTH FUND"), AIM GLOBAL GROWTH FUND
("GROWTH FUND") and AIM GLOBAL INCOME FUND ("INCOME FUND"), (collectively, with
AIM INTERNATIONAL EQUITY FUND, the "Funds") each of which pursues unique
investment objectives. All such other Funds 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 ASIAN FUND, EUROPEAN FUND, AGGRESSIVE GROWTH FUND, GROWTH
FUND, or INCOME FUND, call (800) 347-4246. See "General Information."
 
  The investment objective of the Fund is to provide long-term growth of capital
by investing in a diversified portfolio of international equity securities the
issuers of which are considered by the Fund's investment advisor to have strong
earnings momentum. Any income realized by the Fund will be incidental and will
not be an important criterion in the selection of portfolio securities. Under
normal market conditions, the Fund will invest at least 70% of its total assets
in marketable equity securities (including common and preferred stock,
depositary receipts for stock and other securities having the characteristics of
stock) of companies located outside the United States ("foreign companies")
which are listed on a recognized foreign securities exchange or traded in a
foreign over-the-counter market. The Fund may also invest up to 20% of its total
assets in securities exchangeable for or convertible into equity securities of
foreign companies which are listed on a recognized foreign securities exchange
or traded on a foreign over-the-counter market. Under normal market conditions,
the Fund's assets will be invested in the securities of foreign companies
located in at least four countries outside the United States. The Fund will
emphasize investment in foreign companies in the developed countries of Western
Europe and the Pacific Basin and may also invest to a limited extent in the
securities of companies located in developing countries in various regions of
the world.
 
  Over the past 30 years, securities of foreign companies ("foreign securities")
have offered generally higher levels of capital growth than similar investments
in the United States. The Fund's investment advisor believes that investment in
foreign securities offers significant potential for long-term capital
appreciation. Also, foreign equity markets often do not move in step with each
other or with domestic equity markets. The Fund's investment advisor believes
that a portfolio invested in a number of markets worldwide should thus achieve
better long-term results for investors than one which is subject to the
movements of a single market.
 
  The Fund intends to achieve its investment objective by using a fully managed
investment policy providing for the selection of securities. The Fund will also
seek to spread its investments among countries or regions in accordance with the
investment advisor's assessment of prospects for relative economic growth,
political conditions, currency exchange fluctuations and other relevant factors.
For more complete information on the Fund's investment objective, policies and
strategies, see "Investment Objective and Policies" and "Hedging Strategies and
Other Investment Techniques."
 
  RISK FACTORS. THE FUND IS DESIGNED FOR LONG-TERM INVESTORS SEEKING
INTERNATIONAL DIVERSIFICATION AND WILLING TO BEAR THE RISKS ASSOCIATED WITH
INVESTMENT IN FOREIGN SECURITIES, INCLUDING CURRENCY RISK, POLITICAL AND
ECONOMIC RISK, REGULATORY RISK AND MARKET RISK. IT IS NOT DESIGNED AS A COMPLETE
INVESTMENT PROGRAM. FOR A DISCUSSION OF THESE RISKS, SEE "RISK FACTORS."
 
  MANAGEMENT. A I M Advisors, Inc. ("AIM") serves as the Fund's investment
advisor pursuant to an investment advisory agreement (the "Advisory Agreement").
AIM, together with its subsidiaries, manages or advises over 50 investment
company portfolios encompassing a broad range of investment objectives. Under
the terms of the Advisory Agreement, AIM supervises all aspects of the
 
                                        2
<PAGE>   62
 
Fund's operations and provides investment advisory services to the Fund. As
compensation for these services, AIM receives a fee based on the Fund's average
daily net assets. Under an administrative services agreement (the
"Administrative Services Agreement"), AIM is reimbursed by the Fund for its
costs of performing, or arranging for the performance of, certain accounting and
other administrative services for the Fund. Under a transfer agency and service
agreement ("the 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 for the Fund.
 
  MULTIPLE DISTRIBUTION SYSTEM. Investors may select Class A, Class B or Class C
shares of the Fund 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 of the date
     on which a purchase was made. Class B shares automatically convert to Class
     A shares of the 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.
 
          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 of the date such shares
     were purchased. Class C shares are subject to higher expenses than Class A
     shares.
 
  SUITABILITY FOR INVESTORS. The Multiple Distribution System permits an
investor to choose 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 shares to the
investor who qualifies for reduced initial sales charges, as described below.
Therefore, A I M Distributors, Inc. ("AIM Distributors") intends to reject any
order for purchase of more than $250,000 for Class B shares.
 
  PURCHASING 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 Fund's shares is A I M Distributors, Inc., P.O. Box 4739,
Houston, Texas 77210-4739. See "How to Purchase Shares" and "Special Plans."
 
  EXCHANGE PRIVILEGE. The Fund is one of several mutual funds distributed by AIM
Distributors (collectively, "The AIM Family of Funds"). Class A, Class B and
Class C shares of the Fund 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. Holders of Class A shares may redeem all or a portion of
their shares at net asset value on any business day, generally without charge. A
contingent deferred sales charge of 1% may apply to certain redemptions of Class
A shares, where purchases of $1 million or more are made at net asset value. See
"How to Redeem Shares -- Contingent Deferred Sales Charge Program for Large
Purchases."
 
  Holders of Class B shares 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 following the date on which a purchase was
made. Class B shares redeemed after six years following the date of purchase
will not be subject to any contingent deferred sales charge. See "How to Redeem
Shares -- Multiple Distribution System."
 
  Holders of Class C shares of the Fund 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. Class C shares redeemed after one year 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."
 
  DISTRIBUTIONS. The Fund declares and pays dividends from net investment
income, if any, and makes distributions of realized capital gains, if any, on an
annual basis. Dividends and distributions of the Fund may be reinvested at net
asset value without payment of a sales charge in the Fund's shares or may be
invested in shares 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 the Fund understand the
various costs that an investor will bear, both directly and indirectly. The fees
and expenses for Class A and Class B shares set forth in the table are based on
the average net assets of the respective classes of the Fund for the year ended
October 31, 1997. The fees and expenses for Class C shares set forth in the
table are based on the estimated average net assets of Class C shares of the
Fund for the period August 4 (date sales commenced) to October 31, 1997. 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."

*  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."
 
** If management fees had not been waived, the management fees would have been
   0.93% and total fund operating expenses would have been 1.51%, 2.28% and
   2.28% for the Class A shares, Class B shares and Class C shares,
   respectively.
 
  EXAMPLES. An investor in the Fund would pay the following expenses on a $1,000
investment in Class A shares of the Fund, assuming (1) a 5% annual return and
(2) redemption at the end of each time period:

  An investor would pay the following expenses on the same $1,000 investment in
Class C shares of the Fund, assuming no redemption at the end of each time
period.

</TABLE>
 
  As a result of 12b-1 fees, a long-term shareholder in the Fund may pay more
than the economic equivalent of the maximum front-end sales charges permitted by
rules of the National Association of Securities Dealers, Inc. Given the maximum
front-end sales charge applicable to Class A shares and the Rule 12b-1 fees
applicable to Class A shares, Class B shares and Class C shares, it is estimated
that it would require a substantial number of years to exceed the maximum
permissible front-end sales charges.
 
  THE ABOVE EXAMPLES SHOULD NOT BE CONSIDERED REPRESENTATIVE OF THE FUND'S
ACTUAL OR FUTURE EXPENSES, WHICH MAY BE GREATER OR LESS THAN THOSE SHOWN. In
addition, while the examples assume a 5% annual return, the Fund's actual
performance will vary and may result in an actual return that is greater or less
than 5%. The examples assume reinvestment of all dividends and distributions and
that the percentage amounts for total fund operating expenses remain the same
for each year.

PERFORMANCE
 
  The Fund's performance may be quoted in advertising in terms of total return.
All advertisements of the Fund will disclose the maximum sales charge (including
deferred sales charge) to which investments in the Fund's shares 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 Fund. Further information regarding the Fund's
performance is contained in the Fund's annual report to shareholders, which is
available upon request and without charge.
 
  Standardized total return for Class A shares reflects the deduction of the
maximum initial sales charge at the time of purchase. Standardized total return
for Class B shares 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 reflects the deduction of a 1%
contingent deferred sales charge, if applicable, on a redemption of shares held
for the period.
 
  The Fund's total return shows its overall change in value, including changes
in share price assuming that all the Fund's dividends and capital gain
distributions are reinvested and that all charges and expenses are deducted. A
cumulative total return reflects the Fund's performance over a stated period of
time. An average annual total return reflects the hypothetical compounded annual
rate of 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 THE 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, the Fund may
separate its cumulative and average annual returns into income results and
capital gains or losses. The stated period for quotations of
 
                                        8
<PAGE>   68
 
average annual total return will be for periods of one year and the life of the
Fund (commencing as of the effective date of its registration statement).
 
  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 the Fund. Such a practice will
have the effect of increasing the Fund's total return.
 
  The performance of the Fund will vary from time to time, and past results are
not necessarily representative of future results. The 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 as well
as by general market conditions. A shareholder's investment in the Fund is not
insured or guaranteed. These factors should be carefully considered by the
investor before making an investment in the Fund.
 
- --------------------------------------------------------------------------------
 
INVESTMENT OBJECTIVE AND POLICIES
 
  The investment objective of the Fund, which is a fundamental policy that may
be changed only with the approval of the Fund's shareholders, is to provide
long-term growth of capital by investing in a diversified portfolio of
international equity securities, the issuers of which are considered by AIM to
have strong earnings momentum. Any income realized by the Fund will be
incidental and will not be an important criterion in the selection of portfolio
securities. There can be no assurance that the Fund will achieve its objective.
 
  The Board of Directors of the Company reserves the right to change any of the
investment policies, strategies or practices of the Fund, as described below and
elsewhere in this Prospectus and in the Statement of Additional Information,
without approval of the Fund's shareholders, except in those instances in which
shareholder approval is expressly required.
 
  Under normal market conditions the Fund will invest at least 70% of its total
assets in marketable equity securities, including common stock, preferred stock,
depositary receipts for stock and other securities having the characteristics of
stock (such as an equity or ownership interest in a company) of foreign
companies which are listed on a recognized foreign securities exchange or traded
in a foreign over-the-counter-market. The Fund may satisfy the foregoing
requirement in part by investing in the securities of foreign issuers which are
in the form of American Depositary Receipts ("ADRs"), European Depositary
Receipts ("EDRs"), or other securities representing underlying securities of
foreign issuers. The Fund may also invest up to 20% of its total assets in
securities exchangeable for or convertible into equity securities of foreign
companies which are listed on a recognized foreign securities exchange or traded
in a foreign over-the-counter market.
 
  In managing the Fund, AIM seeks to apply to a diversified portfolio of
international equity securities substantially the same investment strategy which
it applies to several of its other managed portfolios which have similar
investment objectives but which invest primarily in United States equities
markets. The Fund will utilize to the extent practicable a fully managed
investment policy providing for the selection of securities which meet certain
quantitative standards determined by AIM. AIM reviews carefully the earnings
history and prospects for growth of each company considered for investment by
the Fund. It is expected that the Fund's portfolio, when fully invested, will
generally be comprised of two basic categories of foreign companies: (1) "core"
companies, which AIM considers to have experienced consistent long-term growth
in earnings and to have strong prospects for outstanding future growth, and (2)
companies that AIM believes are currently experiencing a greater than
anticipated increase in earnings.
 
  If a particular foreign company meets the quantitative standards determined by
AIM, its securities may be acquired by the Fund regardless of the location of
the company or the percentage of the Fund's investments in the company's country
or region. However, AIM will also consider other factors in making investment
decisions for the Fund, including such factors as the prospects for relative
economic growth among countries or regions, economic and political conditions,
currency exchange fluctuations, tax considerations and the liquidity of a
particular security.
 
  AIM recognizes that often there is less public information about foreign
companies than is available in reports supplied by domestic companies, that
foreign companies are not subject to uniform accounting and financial reporting
standards, and that there may be greater delays experienced by the Fund in
receiving financial information supplied by foreign companies than comparable
information supplied by domestic companies. For these and other reasons, AIM
from time to time may encounter greater difficulty applying its disciplined
stock selection strategy to an international equity investment portfolio than to
a portfolio of domestic equity securities.
 
  AIM may invest a portion of the Fund's assets in (i) cash or high-grade
short-term securities, including repurchase agreements, commercial paper, time
deposits and master notes, denominated either in U.S. dollars or foreign
currencies, (ii) U.S. government obligations or investment grade (high quality)
corporate bonds or other debt securities, and (iii) taxable municipal
securities, when such positions are deemed advisable in light of economic or
market conditions or for daily cash management purposes. In addition, AIM may
invest, for temporary defensive purposes, all or substantially all of the Fund's
assets in the securities described above. To the extent that the Fund is
invested to a significant degree in cash, high-grade short-term securities, U.S.
government obligations, investment grade (high quality) corporate bonds or other
debt securities, or taxable municipal securities, its ability to achieve its
investment objective of growth of capital may be adversely affected. Under
normal circumstances, the Fund will invest no more than 20% of the value of its
total assets in high-grade short-term securities. A repurchase agreement is an
instrument under which the Fund ac-quires 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. In the event of a bankruptcy or other default of a seller
 
                                        9
<PAGE>   69
 
of a repurchase agreement, the 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 reduced levels of income and lack of
access to income during this period and (c) expenses of enforcing its rights.
The Fund intends to enter into repurchase agreements with sellers believed by
AIM to present minimal credit risk. See "Investment Restrictions."
 
  Under normal market conditions, the Fund intends to invest in the securities
of foreign companies located in at least four countries outside the United
States. The Fund will emphasize investment in foreign companies in the developed
countries of Western Europe (such as Germany, France, Switzerland, the
Netherlands and the United Kingdom) and the Pacific Basin (such as Japan, Hong
Kong and Australia), and the Fund may also invest in the securities of companies
located in developing countries (such as Turkey, Malaysia and Mexico) in various
regions of the world. A "developing country" is a country in the initial stages
of its industrial cycle.
 
  Investment in the equity markets of developing countries involves exposure to
securities exchanges 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 than the equity markets of developed
countries. At the present time, AIM does not intend to invest more than 20% of
the Fund's total assets in foreign companies located in developing countries.
 
- --------------------------------------------------------------------------------
 
HEDGING STRATEGIES AND OTHER INVESTMENT TECHNIQUES
 
  The Fund may, at such times as AIM deems appropriate and consistent with the
investment objective of the Fund, write (sell) covered put or call options and
may purchase put or call options on its portfolio securities. The Fund may also
purchase and sell (i) options on domestic and foreign securities and currencies,
(ii) stock index options, (iii) stock, currency and interest rate futures, (iv)
options on stock, currency, stock index and interest rate futures and (v)
foreign forward currency exchange contracts. The purpose of such transactions is
to hedge against changes in the market value of the 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. The Fund will not engage
in such transactions for speculative purposes. The Fund does not intend to hedge
against currency, investment and interest rate risks during the coming year. Any
change to such policy must be submitted by AIM to the Company's Board of
Directors prior to the effectiveness of such change.
 
  To a limited extent the Fund may employ certain investment techniques intended
to provide liquidity for temporary or emergency purposes, provide flexibility in
the purchase of new issues of securities, protect the Fund from a decline in the
market value of its securities and permit the Fund to invest all of its assets.
Those techniques include entering into reverse repurchase agreements, lending
portfolio securities, purchasing securities on a "when-issued" basis, short
sales "against the box" and investing in closed-end investment companies.
 
  OPTIONS. The Fund may purchase put or call options. Such options give the Fund
the right for a fixed period of time to sell (in the case of purchase of a put
option) or to buy (in the case of purchase of a call option) the number of units
of the underlying security or obligation covered by the option at a fixed or
determinable exercise price. Buying a put option hedges against the risk of a
market decline. Buying a call option hedges against a market advance. Prior to
its expiration, a put or call option may be sold in a closing sale transaction.
Gain or loss from such a sale will depend on whether the amount received is more
or less than the premium paid for the option plus the related transaction costs.
 
  The Fund also may write (sell) put or 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). A call option is "covered" if the Fund owns the underlying
security covered by the call. A put option is "covered" if the Fund's custodian
segregates liquid assets with a value equal to the exercise price of the put
option. If a "covered" call or put 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. If the covered put option is exercised,
the writer's cost of purchasing the underlying security is reduced by the amount
of the premium received from the initial sale of the put option. Prior to its
expiration, a put or 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.
 
  The Fund may also purchase and write options in combination with each other to
adjust the risk and return characteristics of certain portfolio security
positions. This technique is commonly referred to as a "collar."
 
  Options are subject to certain risks, including the risk of imperfect
correlation between the option and the Fund's portfolio securities 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 value, 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 Fund will not write options if, immediately after such sale, the aggregate
value of the securities or obligations underlying the outstanding options
exceeds 25% of the Fund's total assets. The Fund will not purchase put options
(including options on securities
 
                                       10
<PAGE>   70
 
indices and futures contracts) if, at the time of investment, the aggregate
premiums paid for such options will exceed 5% of its total assets.
 
  FUTURES AND FORWARD CONTRACTS. Since substantially all of the securities held
by the Fund may be denominated in foreign currencies, the value of the Fund's
portfolio will be affected by changes in exchange rates between currencies
(including the U.S. dollar), as well as by changes in the market value of the
securities themselves. The Fund may enter into interest rate, exchange rate and
currency futures contracts and related options, or it may purchase or sell stock
index futures contracts and related options in order to hedge the value of its
portfolio against changes in market conditions or in exchange rates between
currencies (including the U.S. dollar). Futures contracts obligate the seller to
deliver a specific type of security called for in the contract, at a specified
future time and for a specified price. Futures contracts are traded on U.S. and
foreign exchanges and generally contain standardized strike prices and
expiration dates. Certain futures contracts may be satisfied by actual delivery
of the securities or, more typically, by entering into an offsetting
transaction. An option on a futures contract gives the purchaser the right, in
return for the premium paid, to assume a position in a futures contract. In
addition to purchasing or selling futures contracts on currencies and specific
securities, interest rates and exchange rates, the Fund may purchase or sell
stock index futures contracts. A stock index futures contract is an agreement to
take or make delivery of an amount of cash based on the difference between the
value of a stock index at the beginning and at the end of the contract period.
No more than 5% of the Fund's total assets will be committed to initial margin
deposits required pursuant to futures contracts. Percentage investment
limitations on the Fund's investment in options on futures contracts and asset
coverage requirements are set forth above under "Options." Although the Fund is
authorized to invest in futures contracts and related options with respect to
foreign securities, stock indices, interest rates and currencies, it will limit
such investments to those which have been approved by the Commodity Futures
Trading Commission for investment by United States investors.
 
  In attempting to manage its currency exposure, the Fund may buy and sell
currencies, either in the spot (cash) market or in the forward market (through
forward contracts generally expiring within one year). The Fund may also enter
into forward contracts with respect to a specific purchase or sale of a
security, or with respect to its portfolio positions generally. When the Fund
purchases a security for settlement in the near future, it may immediately
purchase in the forward market the currency needed to pay for and settle the
purchase. By entering into a forward contract with respect to the specific
purchase or sale of a security denominated in a foreign currency, the Fund can
secure an exchange rate between the trade and settlement dates for that purchase
or sale transaction. This practice is sometimes referred to as "transaction
hedging." Unlike futures contracts, forward contracts are generally individually
negotiated and privately traded. A forward contract obligates the seller to sell
a specific security or currency at a specified price on a future date, which may
be any fixed number of days from the date of the contract. The Fund may enter
into transaction hedging forward contracts with respect to all or a substantial
portion of its trades. The Fund will not enter into a position hedging
commitment if, as a result thereof, the Fund would have more than 10% of the
value of its total assets committed to such contracts. The Fund will not enter
into a forward contract with a term of more than one year.
 
  There are risks associated with the use of futures and forward contracts and
options thereon for hedging purposes. During certain market conditions, sales of
futures contracts may not completely offset a decline or rise in the value of
the Fund's portfolio securities or currency against which the futures or forward
contract or options thereon are being sold. In the futures and options on
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. Risks in the use of
futures contracts and options thereon also result from the possibility that
changes in the market value of securities or currency may differ substantially
from the changes anticipated by the Fund when hedged positions were established.
Successful use of futures and forward contracts and options thereon is dependent
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. Accordingly, the Fund may lose the expected benefit of
futures and forward transactions and options thereon if markets move in an
unanticipated manner.
 
  OTHER HEDGING TECHNIQUES. For hedging purposes, the Fund may also purchase
foreign currencies in the form of bank deposits as well as other foreign money
market instruments, including, but not limited to, bankers' acceptances,
certificates of deposit, commercial paper, short-term government and corporate
obligations and repurchase agreements.
 
  REPURCHASE AGREEMENTS. The Fund may enter into repurchase agreements with
institutions believed by the Company's Board of Directors to present minimal
credit risk. 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. In the event of
a bankruptcy or other default of a seller of a repurchase agreement (such as the
sellers' failure to repurchase the obligation in accordance with the terms of
the 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 reduced levels of income and lack of access to
income during this period; and (d) expenses of enforcing its rights. Repurchase
agreements are considered to be loans by the Fund under the Investment Company
Act of 1940, as amended (the "1940 Act"). Repurchase agreements will be secured
by U.S. Treasury securities, U.S. Government agency securities (including, but
not limited to, those which have been stripped of their interest payments and
mortgage-backed securities) and commercial paper. For additional information on
the use of repurchase agreements, see the Statement of Additional Information.
 
  REVERSE REPURCHASE AGREEMENTS. The Fund may invest in reverse repurchase
agreements, 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
                                       11
<PAGE>   71
 
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 assets having a dollar
value equal to the repurchase price. Reverse repurchase agreements are
considered borrowings by the Fund under the 1940 Act. The Fund may enter into
reverse repurchase agreements in amounts not exceeding 33 1/3% of the value of
its total assets. Reverse repurchase agreements involve the risk that the market
value of securities retained by the Fund in lieu of liquidation may decline
below the repurchase price of the securities sold by the Fund which it is
obligated to repurchase. This risk, if encountered, could cause a reduction in
the net asset value of the Fund's shares.
 
  LENDING OF PORTFOLIO SECURITIES. The Fund may from time to time lend
securities from its portfolio, with a value not exceeding 33 1/3% of its total
assets, to banks, brokers and other financial institutions, and receive in
return collateral in the form of cash or securities issued or guaranteed by the
U.S. Government which will be maintained at all times in an amount equal to at
least 100% of the current market value of the loaned securities. During the
period of the loan, the Fund receives the income on both the loaned securities
and the collateral and thereby increases its yield. In the event that the
borrower defaults on its obligation to return loaned securities because of
insolvency or otherwise, the Fund could experience delays and costs in gaining
access to the collateral and could suffer a loss to the extent that the value of
the collateral falls below the market value of the loaned securities.
 
  SECURITIES ISSUED ON A WHEN-ISSUED OR DELAYED DELIVERY BASIS. The Fund may
purchase securities on a "when-issued" basis, that is, delivery of and payment
of 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). The 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. The 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. If the Fund purchases a when-issued
security or enters into a delayed delivery agreement, the Fund's custodian bank
will segregate liquid assets in an amount at least equal to the when-issued
commitment or delayed delivery agreement commitment.
 
  SHORT SALES. The Fund may make short sales "against the box." A short sale is
a transaction in which a party sells a security it does not own in anticipation
of a decline in the market value of that security. A short sale is "against the
box" to the extent that the Fund contemporaneously owns or has the right to
obtain securities identical to those sold short without payment of any further
consideration. The Fund will enter into such transactions only to the extent the
aggregate value of all securities sold short does not represent more than 10% of
the Fund's assets at any given time.
 
  ILLIQUID SECURITIES AND RULE 144A SECURITIES. The Fund may invest up to 15% of
its net assets in securities that are illiquid. Illiquid securities include
securities that have no readily available market quotations and cannot be
disposed of promptly (within seven days) in the normal course of business at a
price at which they are valued. Illiquid securities may include securities that
are subject to restrictions on resale because they have not been registered
under the Securities Act of 1933. Unregistered securities may, in certain
circumstances, be resold pursuant to Rule 144A, and thus may or may not
constitute illiquid securities. Limitations on the resale of unregistered
securities may have an adverse effect on their marketability, which may prevent
the Fund from disposing of them promptly at reasonable prices. The Fund may have
to bear the expense of registering such securities for resale, and the risk of
substantial delays in effecting such registrations. The Company's Board of
Directors is responsible for developing and establishing guidelines and
procedures for determining the liquidity of Rule 144A securities on behalf of
the Fund and monitoring AIM's implementation of the guidelines and procedures.
 
  INVESTMENT IN OTHER INVESTMENT COMPANIES. The Fund may invest in other
investment companies to the extent permitted by the 1940 Act, and rules and
regulations thereunder, and, if applicable, exemptive orders granted by the SEC.
 
- --------------------------------------------------------------------------------
 
RISK FACTORS
 
  There can be no assurance that the Fund's investment objective will be
attained. The Fund is designed for investors seeking international
diversification, and is not intended as a complete investment program. In
addition, investing in securities of foreign companies generally involves
greater risks than investing in securities of domestic companies. Investors
should consider carefully the following special factors before investing in the
Fund.
 
  CURRENCY RISK. The value of the Fund's foreign investments may be affected by
changes in currency exchange rates. The U.S. dollar value of a foreign security
generally decreases when the value of the U.S. dollar rises against the foreign
currency in which the security is denominated, and tends to increase 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 Fund 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 the Fund's investments.
 
                                       12
<PAGE>   72
 
  REGULATORY RISK. Foreign companies 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 Fund may be reduced by withholding tax at the
source which would reduce dividend income payable to the Fund's shareholders.
 
  MARKET RISK. The securities markets in many of the countries in which the Fund
invests 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.
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. Further, the
settlement period of securities transactions in foreign markets may be longer
than in domestic markets. These considerations generally are more of a concern
in developing countries. For example, the possibility of revolution and the
dependence on foreign economic assistance may be greater in these countries than
in developed countries. The management of the Funds seeks to mitigate the risks
associated with these considerations through diversification and active
professional management.

INVESTMENT RESTRICTIONS
 
  The following restrictions may not be changed without approval of the Fund's
shareholders. The Fund may not:
 
          1. Purchase a security if, as a result, with respect to 75% of the
     value of the Fund's total assets, taken at market value, more than 5% of
     the value of the Fund's total assets, taken at market value, would be
     invested in securities of any one issuer (including repurchase agreements
     with any one entity), except securities issued or guaranteed by the U.S.
     Government or any of its agencies or instrumentalities and except that the
     Fund may purchase securities of other investment companies to the extent
     permitted by applicable law or exemptive order.
 
          2. Purchase a security if, as a result, more than 10% of the
     outstanding voting securities of any issuer would be held by the Fund,
     except that the Fund may purchase securities of other investment companies
     to the extent permitted by applicable law or exemptive order.
 
          3. Purchase a security if, as a result, 25% or more of the value of
     the Fund's total assets, taken at market value, would be invested in the
     securities of issuers having their principal business activities in the
     same industry. This restriction does not apply to obligations issued or
     guaranteed by the U.S. Government or by any of its agencies or
     instrumentalities but will apply to foreign government obligations unless
     the SEC permits their exclusion.
 
          4. Borrow money, except that the Fund may borrow from banks (including
     the Fund's custodian bank) and enter into reverse repurchase agreements as
     a temporary defensive measure for extraordinary or emergency purposes, and
     then only in amounts not exceeding 10% of its total assets, taken at market
     value, and may pledge amounts of up to 20% of its total assets, taken at
     market value, to secure such borrowings. For purposes of this restriction,
     collateral arrangements with respect to the writing of options, futures
     contracts, options on futures contracts, and collateral arrangements with
     respect to initial and variation margin are not deemed to be a pledge of
     assets and neither such arrangements nor the purchase and sale of options,
     futures or related options shall be deemed to be the issuance of a senior
     security. Whenever bank borrowings and the value of the Fund's reverse
     repurchase agreements exceed 5% of the value of the Fund's total assets,
     the Fund will not make any additional purchases of securities for
     investment purposes.
 
  A complete listing of investment restrictions applicable to the Fund, some of
which may be changed by the Board of Directors without shareholder approval, is
contained in the Statement of Additional Information.

  INVESTMENT ADVISOR. A I M Advisors, Inc., 11 Greenway Plaza, Suite 100,
Houston, Texas 77046, serves as the investment advisor to the Fund pursuant to a
Master Investment Advisory Agreement dated as of February 28, 1997. AIM was
organized in 1976 and, together with its subsidiaries, manages or advises over
50 investment company portfolios encompassing a broad range of investment
objectives.
 
  Under the terms of the Advisory Agreement, AIM supervises all aspects of the
Fund's operations and provides investment advisory services to the Fund. AIM
obtains and evaluates economic, statistical and financial information to
formulate and implement investment programs for the Fund.
 
  ADMINISTRATOR. AIM and the Company have entered into a Master Administrative
Services Agreement, dated as of February 28, 1997, pursuant to which AIM has
agreed to provide or arrange for the provision of certain accounting and other
administrative services to the Fund. AIM is entitled to receive from the Fund
reimbursement of its costs or such reasonable compensation as may be approved by
the Board of Directors. Currently, AIM is reimbursed for the services of the
Fund's principal financial officer and his staff, and any expenses related to
such services.
 
  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 Fund and other funds advised by
AIM in selecting broker-dealers to effect portfolio transactions on behalf of
the Fund.
 
  PORTFOLIO MANAGEMENT. AIM uses a team approach and disciplined investment
strategy in providing investment advisory services to all its accounts,
including the Fund. 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 regular basis by AIM's Investment Policy
Committee to ensure that they are being invested in accordance with the
accounts' and AIM's investment policies. A. Dale Griffin, III, Clas G. Olsson,
Paul A. Rogge and Barrett K. Sides are primarily responsible for the day-to-day
management of the Fund. Mr. Griffin is Vice President of A I M Capital
Management, Inc. ("AIM Capital"), a wholly owned subsidiary of AIM, and has been
responsible for the Fund since its inception in 1992. He has been associated
with AIM and/or its subsidiaries since 1989 and began working as an investment
professional in 1987. Mr. Olsson is an Investment Officer of AIM Capital and has
been responsible for the Fund since 1997. He has been associated with AIM and/or
its subsidiaries since 1994 and began working as an investment professional in
1994. Prior to 1994, Mr. Olsson was a broker assistant trainee with Merrill
Lynch, Pierce, Fenner & Smith Incorporated. Mr. Rogge is Vice President of AIM
Capital and also has been responsible for the Fund since its inception in 1992.
He has been associated with AIM and/or its subsidiaries since he began working
as an investment professional in 1991. Mr. Sides is Assistant Vice President of
AIM Capital and has been responsible for the Fund since 1995. He has been
associated with AIM and/or its subsidiaries since he began working as an
investment professional in 1990.
 
  FEES AND EXPENSES. For the year ended October 31, 1997, the Fund paid AIM an
amount for its advisory services which represented 0.89% of the Fund's average
daily net assets. Although the fee payable to AIM under the Advisory Agreement
is higher than that paid by most mutual funds which invest in domestic
securities, it is competitive with such fees paid by mutual funds which invest
primarily in foreign securities. The Company believes such fee is justified due
to the higher costs and additional expenses associated with managing and
operating a fund holding primarily foreign equity securities. For the year ended
October 31, 1997, the Fund reimbursed AIM for administrative services costs
pursuant to the Administrative Services Agreement an amount which represented
0.01% of the Fund's average daily net assets. The Class A shares' total expenses
for such year were 1.47% of the Class A shares' average daily net assets. The
Class B shares' total expenses for such year were 2.25% of the Class B shares'
average daily net assets. The Class C shares' total expenses for the period
August 4, 1997 (date sales commenced) through October 31, 1997 were 2.25% of the
Class C shares' average daily net assets.
 
  In addition, the Company and A I M Fund Services, Inc. P.O. Box 4739, Houston,
TX 77210-4739, a wholly owned subsidiary of AIM and registered transfer agent,
have entered into a Transfer Agency and Service Agreement, pursuant to which AFS
provides transfer agency, dividend distribution and disbursement, and
shareholder services to the Fund.
 
  FEE WAIVERS. AIM may from time to time voluntarily waive or reduce its fees,
while retaining its ability to be reimbursed for such fees prior to the end of
each fiscal year. Fee waivers or reductions, other than those contained in the
Advisory Agreement, may be modified or terminated at any time and without notice
to investors. AIM has voluntarily agreed to waive its advisory fees under the
Advisory Agreement in order to achieve the following annual fee structure for
the Fund: 0.95% of the first $500 million of the Fund's average daily net
assets; 0.90% of the next $500 million of the Fund's average daily net assets;
and 0.85% of the Fund's average daily net assets exceeding $1 billion. For the
fiscal year ended October 31, 1997, AIM waived advisory fees for the Fund which
represented 0.04% of the Fund's average daily net assets.
 
  DISTRIBUTOR. The Company has entered into Master Distribution Agreements on
behalf of the Fund (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 Fund. The address of
A I M Distributors, Inc. is P.O. Box 4739, Houston, Texas 77021-4739. 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 Fund 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 at net
asset value subject to a contingent deferred sales charge established by AIM
 
                                       14
<PAGE>   74
 
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
the 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 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 the 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 the 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
the Fund on an annualized basis and an aggregate amount of 1.00% of the average
daily net assets of Class C shares of the 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 the 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
the 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.
 
  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, the Fund pays distribution expenses at an annual rate of 1.00% of the
average daily net assets attributable to the Class B shares. Of such amount, the
Fund pays a service fee of 0.25% of the average daily net assets attributable to
the 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 may be used to finance any activity primarily intended to result in
the sale of Class B shares.
 
  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, 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 the Fund under the Plans need not be directly related
to the expenses actually incurred by AIM Distributors on behalf of the 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 the
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 fee that has not been
assigned or transferred, 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 Fund pursuant to the respective Plans. AIM
Distributors does not act as principal, but
 
                                       15
<PAGE>   75
 
rather as agent, for the Fund in making such payments. Financial intermediaries
and any other person entitled to receive compensation for selling Fund shares
may receive different compensation for selling shares of one particular class
over another.
 
  For additional information concerning the operation of the Plans, see the
Statement of Additional Information.

ORGANIZATION OF THE COMPANY
 
  The Company was organized in 1991 as a Maryland corporation, and is registered
with the SEC as an open-end series management investment company. The Company
currently consists of six investment portfolios: the Fund, AIM ASIAN GROWTH
FUND, AIM EUROPEAN DEVELOPMENT FUND, AIM GLOBAL AGGRESSIVE GROWTH FUND, AIM
GLOBAL GROWTH FUND and AIM GLOBAL INCOME FUND. The Board of Directors may
authorize additional portfolios in the future. Shares of the Fund are offered to
investors pursuant to this Prospectus, while shares of the Company's other
portfolios are offered to investors pursuant to separate prospectuses. The
authorized capital stock of the Company consists of 4,000,000,000 shares of
common stock with a par value of $0.001 per share, of which 200,000,000 shares
are designated Class A shares, 200,000,000 shares are designated Class B shares
and 200,000,000 shares are designated Class C shares of each investment
portfolio of the Company, and the balance of which are unclassified.
 
  Class A shares, Class B shares and Class C shares of the Fund represent
interests in the 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 ex-penses (such as those associated with
the shareholder servicing of their shares) and is subject to differing sales
loads (which may affect performance), 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 the Fund are entitled to
one vote per share (with proportionate voting for fractional shares),
irrespective of the relative net asset value of the Class A shares, Class B
shares and Class C shares of the 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 the 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.
 
  Under Maryland law and the Company's By-Laws, the Company need not hold an
annual meeting of shareholders unless a meeting is otherwise required under the
1940 Act to elect directors. As of February 2, 1998, Merrill Lynch, Pierce,
Fenner & Smith Incorporated was the owner of record of 33.13%, 36.84% and 47.42%
of the outstanding Class A, Class B and Class C shares, respectively, of the
Fund. As long as Merrill Lynch, Pierce, Fenner & Smith Incorporated owns over
25% of such shares, it may be presumed to be in "control" of the Class A, Class
B and Class C shares of the Fund, 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.

  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.

  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

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

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) 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
 
   
                                                                       MCF-02/98

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).

  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>   88
 
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

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
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).
 
  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
Code Section 401 (collectively, "Retirement Plans"), (3) 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 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;
 
          (iii) tax-free rollovers or transfers of assets to another Retirement
     Plan invested in Class B or Class C shares of one or more Multiple Class
     Funds;
 
          (iv) tax-free returns of excess contributions or returns of excess
     deferral amounts; and
 
          (v) distributions upon the death or disability (as defined in the
     Code) of the participant or beneficiary.

  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
    
   
                                                                       MCF-02/98

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.
 
  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.

  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
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such
 
   
                                                                       MCF-02/98
    
   
    
                                      A-18
<PAGE>   94
 
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

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.

  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.

  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.

  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
shares held by the Transfer Agent in the designated account(s), or in any other
account with any of the AIM Funds, present or future, which has the identical
registration as the designated account(s), with full power of substitution in
the premises. 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
of the shares being redeemed. An investor acknowledges by signing the form that
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
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. 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.
Then any exchanges must be effected in writing by the investor (see the
applicable Fund's prospectus under the caption "Exchange Privilege -- Exchanges
by Mail").

                        Supplement dated October 1, 1998
    to the Prospectus dated February 20, 1998, as supplemented June 30, 1998
 
The following paragraph should be inserted under the heading of "Foreign
Securities -- Currency Risk" on page 21:
 
     "Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg,
     the Netherlands, Portugal, and Spain are members of the European Economic
     and Monetary Union (the "EMU"). The EMU intends to establish a common
     European currency for participating countries which will be known as the
     "euro." It is anticipated that each participating country will supplement
     its existing currency with the euro on January 1, 1999, and will replace
     its existing currency with the euro on July 1, 2002. Any other European
     country that is a member of the European Union and satisfies the criteria
     for participation in the EMU may elect to participate in the EMU and may
     supplement its existing currency with the euro after January 1, 1999.
 
     The expected introduction of the euro presents unique risks and
     uncertainties, including whether the payment and operational systems of
     banks and other financial institutions will be ready by January 1, 1999;
     how outstanding financial contracts will be treated after January 1, 1999;
     the establishment of exchange rates for existing currencies and the euro;
     and the creation of suitable clearing and settlement systems for the euro.
     These and other factors could cause market disruptions before or after the
     introduction of the euro and could adversely affect the value of securities
     held by the Portfolio."
 
The following paragraph replaces in its entirety the third paragraph under the
heading "MANAGEMENT -- Portfolio Management" on page 24 of the prospectus:
 
     "A. Dale Griffin, III, Paul A. Rogge and Jonathan C. Schoolar are primarily
     responsible for the day-to-day management of Growth Fund. Background
     information for Mr. Griffin and Mr. Rogge is discussed above with respect
     to the management of Aggressive Growth Fund. Mr. Griffin and Mr. Rogge have
     been responsible for the Fund since its inception in 1994. Mr. Schoolar is
     a Senior Vice President of AIM Capital, Vice President of AIM, Vice
     President of the Company and has been responsible for the Fund since its
     inception in 1994. He has been associated with AIM and/or its subsidiaries
     since 1986 and began working as an investment professional in 1984."

                   to the Prospectus dated February 20, 1998
 
The third sentence in the second paragraph under the caption "HEDGING
STRATEGIES -- Options" on page 18 is deleted and replaced in its entirety by the
following:
 
     "A put option is 'covered' if a Fund segregates liquid assets with a value
     equal to the exercise price of the put option."
 
The following paragraphs are inserted as a new item under "OTHER INVESTMENT
TECHNIQUES," after "Investment in Other Investment Companies" on page 21 of the
prospectus:
 
     "REAL ESTATE INVESTMENT TRUSTS ("REITS"). To the extent consistent with the
     Funds' investment objectives and policies, the Funds may invest in equity
     and/or debt securities issued by REITs. Such investments will not exceed 5%
     of the total assets of any of the Funds.
 
     REITs are trusts which sell equity or debt securities to investors and use
     the proceeds to invest in real estate or interests therein. A REIT may
     focus on particular projects, such as apartment complexes, or geographic
     regions, such as the Southeastern United States, or both.
 
     To the extent that a Fund has the ability to invest in REITs, such Fund
     could conceivably own real estate directly as a result of a default on the
     securities it owns. A Fund, therefore, may be subject to certain risks
     associated with the direct ownership of real estate including difficulties
     in valuing and trading real estate, declines in the value of real estate,
     risks related to general and local economic condition, adverse change in
     the climate for real estate, increases in property taxes and operating
     expense, changes in zoning laws, casualty or condemnation losses,
     limitations on rents, changes in neighborhood values, the appeal of
     properties to tenants, and increases in interest rates.
 
     In addition to the risks described above, equity REITs may be affected by
     any changes in the value of the underlying property owned by the trusts,
     while mortgage REITs may be affected by the quality of any credit extended.
     Equity and mortgage REITs are dependent upon management skill, are not
     diversified, and are therefore subject to the risk of financing single or a
     limited number of projects. Such trusts are also subject to heavy cash flow
     dependency, defaults by borrowers, self-liquidation, and the possibility of
     failing to maintain exemption from the 1940 Act. Changes in interest rates
     may also affect the value of debt securities held by a Fund. By investing
     in REITs indirectly through a Fund, a shareholder will bear not only
     his/her proportionate share of the expenses of the Fund, but also,
     indirectly, similar expenses of the REITs."
 
The following paragraphs should be inserted under the heading of "Foreign
Securities -- Currency Risk" on page 21:
 
     "Austria, Belgium, Finland, France, Germany, Ireland, Italy, Luxembourg,
     the Netherlands, Portugal, and Spain are members of the European Economic
     and Monetary Union (the "EEMU"). The EEMU intends to establish a common
     European currency for participating countries which will be known as the
     "euro." It is anticipated that each participating country will supplement
     its existing currency with the euro on January 1, 1999, and will replace
     its existing currency with the euro on July 1, 2002. Any other European
     country which is a member of the EEMU may elect to participate in the EEMU
     and may supplement its existing currency with the euro after January 1,
     1999.
 
     The expected introduction of the euro presents unique risks and
     uncertainties, including whether the payment and operational systems of
     banks and other financial institutions will be ready by January 1, 1999;
     how outstanding financial contracts will be treated after January 1, 1999;
     the establishment of exchange rates for existing currencies and the euro;
     and the creation of suitable clearing and settlement systems for the euro.
     These and other factors could cause market disruptions before or after the
     introduction of the euro and could adversely affect the value of securities
     held by the Portfolio."

- --------------------------------------------------------------------------------
 
  THE FUNDS. AIM International Funds, Inc. (the "Company") is a Maryland
corporation organized as an open-end, series, management investment company.
Currently, the Company offers six separate series portfolios. Three of these
series are offered pursuant to this Prospectus: AIM GLOBAL AGGRESSIVE GROWTH
FUND ("AGGRESSIVE GROWTH FUND"), AIM GLOBAL GROWTH FUND ("GROWTH FUND") and AIM
GLOBAL INCOME FUND ("INCOME FUND")(individually, a "Fund" and collectively, the
"Funds"), each of which pursues unique investment objectives. The AGGRESSIVE
GROWTH FUND and the GROWTH FUND are diversified investment portfolios; the
INCOME FUND is a non-diversified investment portfolio. For more complete
information on the Funds' investment objectives and policies, see "Investment
Objectives and Policies."
 
  The Company also offers other classes of shares in three other investment
portfolios, AIM ASIAN GROWTH FUND ("ASIAN FUND"), AIM EUROPEAN DEVELOPMENT FUND
("EUROPEAN FUND") and AIM INTERNATIONAL EQUITY FUND ("EQUITY FUND")
(collectively, with AGGRESSIVE GROWTH FUND, GROWTH FUND and INCOME FUND, the
"Funds") each of which pursues unique investment objectives. All such other
Funds 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 ASIAN FUND,
EUROPEAN FUND or EQUITY FUND, call (800) 347-4246. See "General Information."
 
  RISK FACTORS. EACH FUND IS DESIGNED FOR LONG-TERM INVESTORS SEEKING GLOBAL
DIVERSIFICATION AND WILLING TO BEAR THE RISKS ASSOCIATED WITH INVESTMENTS IN
FOREIGN SECURITIES, INCLUDING CURRENCY RISK, POLITICAL AND ECONOMIC RISK,
REGULATORY RISK AND MARKET RISK. THE INCOME FUND IS A NON-DIVERSIFIED PORTFOLIO,
AND MAY ALSO INVEST IN HIGH YIELD SECURITIES (I.E., "JUNK BONDS") THAT ENTAIL
CERTAIN RISKS. NONE OF THE FUNDS IS DESIGNED AS A COMPLETE INVESTMENT PROGRAM.
FOR A DISCUSSION OF THESE RISKS, SEE "RISK FACTORS." THE INCOME FUND MAY ENGAGE
IN LEVERAGING WHICH MAY INVOLVE AN INCREASE IN RISK. SEE "OTHER INVESTMENT
TECHNIQUES -- BORROWING."
 
  MANAGEMENT. A I M Advisors, Inc. ("AIM") serves as the Funds' investment
advisor pursuant to an investment advisory agreement (the "Advisory Agreement").
AIM, together with its subsidiaries, manages or advises over 50 investment
company portfolios encompassing a broad range of investment objectives. Under
the terms of the Advisory Agreement, AIM supervises all aspects of the Funds'
operations and provides investment advisory services to the Funds. As
compensation for these services, AIM receives a fee based on each Fund's average
daily net assets. Under an administrative services agreement (the
"Administrative Services Agreement"), AIM is reimbursed by each Fund for its
costs of performing, or arranging for the performance of, certain accounting and
other administrative services for each Fund. Under a transfer agency and service
agreement (the "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 for each Fund.
 
  MULTIPLE DISTRIBUTION SYSTEM. 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 of the date
     on which a purchase was made.
 
                                        2
<PAGE>   104
 
     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.
 
          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 of the date such shares
     were purchased.
 
  SUITABILITY FOR INVESTORS. The Multiple Distribution System permits an
investor to choose 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 a Fund and other circumstances. Investors should consider whether, during the
anticipated life of their investment in a 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 to the investor who qualifies for reduced initial
sales charges, as described below. Therefore, A I M Distributors, Inc. ("AIM
Distributors") will reject any order for purchase of more than $250,000 for
Class B shares.
 
  PURCHASING 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., P.O. Box 4739,
Houston, Texas 77210-4739. See "How to Purchase Shares" and "Special Plans."
 
  EXCHANGE PRIVILEGE. The Funds are several of the mutual funds distributed by
AIM Distributors (collectively, "The AIM Family of Funds"). Class A, Class B and
Class C shares of each Fund 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. Holders of Class A shares may redeem all or a portion of
their shares at net asset value on any business day, generally without charge. A
contingent deferred sales charge of 1% may apply to certain redemptions of Class
A shares, where purchases of shares in an amount of $1 million or more are made
at net asset value. See "How to Redeem Shares -- Contingent Deferred Sales
Charge Program for Large Purchases."
 
  Holders of Class B shares 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 following the date on which a purchase was
made. Class B shares redeemed after six years following the date of purchase
will not be subject to any contingent deferred sales charge. See "How to Redeem
Shares -- Multiple Distribution System."
 
  Holders of Class C shares 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. AGGRESSIVE GROWTH FUND and GROWTH FUND declare and pay
dividends from net investment income, if any, and make distributions of realized
capital gains, if any, on an annual basis. INCOME FUND declares dividends from
net investment income on a daily basis and pays such dividends monthly. INCOME
FUND declares and makes distributions of realized short-term capital gains, if
any, annually, and of realized long-term capital gains, if any, annually.
Dividends and distributions of the Funds may be reinvested at net asset value
without payment of a sales charge in the Funds' shares or may be invested in
shares 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 the Funds understand
the various costs that an investor will bear, both directly and indirectly. The
fees and expenses for Class A and Class B shares set forth in the table are
based on the average net assets of the respective classes of the Funds for the
year ended October 31, 1997. The fees and expenses for Class C shares set forth
in the table are based on the estimated average net assets of Class C shares of
the Funds for the period August 4, 1997 (date sales commenced) to October 31,
1997. 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."

  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 rules of
the National Association of Securities Dealers, Inc. Given the maximum front-end
sales charge applicable to Class A shares and the Rule 12b-1 fees applicable to
Class A shares, Class B shares and Class C shares, it is estimated that it would
require a substantial number of years to exceed the maximum permissible
front-end sales charges.
 
  THE ABOVE EXAMPLES SHOULD NOT BE CONSIDERED REPRESENTATIVE OF A PARTICULAR
FUND'S ACTUAL OR FUTURE EXPENSES, WHICH MAY BE GREATER OR LESS THAN THOSE SHOWN.
In addition, while the examples assume a 5% annual return, a Fund's actual
performance will vary and may result in an actual return that is greater or less
than 5%. The examples assume reinvestment of all dividends and distributions and
that the percentage amounts for total fund operating expenses remain the same
for each year.

PERFORMANCE
 
  The performance of each Fund may be quoted in advertising in terms of total
return, and the performance of INCOME FUND may also be quoted in terms of yield.
All advertisements of a Fund 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 the Funds'
performance is contained in the Funds' annual reports to shareholders, which are
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.
 
  Each Fund's total return shows its overall change in value, including changes
in share price assuming that 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 compounded annual
rate of 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 gains or
losses.
 
  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, the
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 reflects
investment income net of expenses over the relevant period attributable to a
share of the Fund, expressed as an annualized percentage of the maximum offering
price per share of the Fund. It is a function of the type and quality of a
Fund's investments, its maturity and its 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 the Fund's yield and total return.
 
  The performance of each Fund will vary from time to time, and past results are
not necessarily representative of future results. Each 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 as well
as by general market conditions. A shareholder's investment in any of the Funds
is not insured or guaranteed. These factors should be carefully considered by
the investor before making an investment in a Fund.
 
- --------------------------------------------------------------------------------
 
INVESTMENT OBJECTIVES AND POLICIES
 
  Each of the Funds has its own investment objective and investment program as
discussed herein. The Funds' investment objective(s) are fundamental policies
that cannot be changed without shareholder approval. There can, of course, be no
assurance that any Fund will in fact achieve its objective(s). 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 GLOBAL AGGRESSIVE GROWTH FUND. The investment objective of AGGRESSIVE
GROWTH FUND is to provide above-average long-term growth of capital
appreciation. The Fund seeks to achieve its objective by investing in a
portfolio of global equity securities including securities of selected companies
with relatively small market capitalization.
 
  The AGGRESSIVE GROWTH FUND will invest in companies throughout the world which
AIM believes possess exceptional growth potential 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 AGGRESSIVE
GROWTH 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 AGGRESSIVE GROWTH FUND as equivalent to a complete investment program.
AGGRESSIVE GROWTH FUND will emphasize investment in small to medium-sized
companies, but its strategy does not preclude investment in large, seasoned
companies which in AIM's judgment possess superior potential returns similar to
companies with formative growth profiles. The Fund will also invest in
established smaller companies (under $1 billion in market capitalization) which
in AIM's judgment offer exceptional value based upon substantially above average
earnings growth potential relative to market value. Investors should realize
that equity securities of small to medium-sized companies may involve greater
risk than is associated with investing in more established companies. Small to
medium-sized companies often have limited product and market diversification,
fewer financial and managerial resources or may be dependent on a few key
managers. Also, because smaller companies normally have fewer shares outstanding
than larger companies and trade less frequently, it may be more difficult for
the Fund to buy and sell shares without an unfavorable impact on prevailing
market prices. Some of the companies in
 
                                       15
<PAGE>   117
 
which the Fund may invest may distribute, sell or produce products which have
recently been brought to market. Any of the foregoing may change suddenly and
have an immediate impact on the value of the Fund's investments. Furthermore,
whenever the securities markets have experienced rapid price changes due to
national economic trends, secondary growth securities have historically been
subject to exaggerated price changes.
 
  AIM GLOBAL GROWTH FUND. The investment objective of GROWTH FUND is to provide
long-term growth of capital. The Fund seeks to achieve its objective by
investing in a portfolio of global equity securities of selected companies that
are considered by AIM to have strong earnings momentum. Current income will not
be an important criterion of investment selection, and any such income should be
considered incidental.
 
  In managing both AGGRESSIVE GROWTH FUND and GROWTH FUND, AIM seeks to apply to
each of the diversified portfolios of equity securities the same investment
strategy which it applies to several of its other managed portfolios which have
similar investment objectives but which invest primarily in United States
equities markets. Each of AGGRESSIVE GROWTH FUND and GROWTH FUND will utilize to
the extent practicable a fully managed investment policy providing for the
selection of securities which meet certain quantitative standards determined by
AIM. AIM reviews carefully the earnings history and prospects for growth of each
company considered for investment by each of the two Funds. It is anticipated
that common stocks will be the principal form of investment of AGGRESSIVE GROWTH
FUND and GROWTH FUND. The portfolio of each of the two Funds is primarily
comprised of securities of two basic categories of companies: (a) "core"
companies, which AIM 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 AIM believes are
currently enjoying a dramatic increase in earnings.
 
  Under normal market conditions, AGGRESSIVE GROWTH FUND and GROWTH FUND will
invest primarily in marketable equity securities (including common and preferred
stock and other securities having the characteristics of stock (such as an
equity or ownership interest in a company)) of companies which are listed on a
recognized securities exchange or traded in an over-the-counter market. Each of
these Funds may satisfy the foregoing requirement in part by investing in the
securities of issuers which are in the form of American Depositary Receipts
("ADRs"), European Depositary Receipts ("EDRs"), or other securities
representing underlying securities of foreign issuers. Each of AGGRESSIVE GROWTH
FUND and GROWTH FUND may invest up to 20% of its total assets in securities
convertible into or exchangeable for equity securities of foreign and domestic
issuers which (except in the case of ADRs, EDRs and other securities
representing underlying securities of foreign issuers) are listed on a
recognized securities exchange or traded in an over-the-counter market.
 
  If a particular foreign company meets the quantitative standards determined by
AIM, its securities may be acquired by a Fund regardless of the location of the
company or the percentage of the Fund's investments in the company's country or
region. However, AIM will also consider other factors in making investment
decisions for these Funds, including such factors as the prospects for relative
economic growth among countries or regions, economic and political conditions,
currency exchange fluctuations, tax considerations and the liquidity of a
particular security. Under normal market conditions, AGGRESSIVE GROWTH FUND and
GROWTH FUND will maintain at least 20% of their respective total assets in U.S.
dollar denominated securities.
 
  AIM recognizes that often there is less public information about foreign
companies than is available in reports supplied by domestic companies, that
foreign companies are not subject to uniform accounting and financial reporting
standards, and that there may be greater delays experienced by a Fund in
receiving financial information supplied by foreign companies than comparable
information supplied by domestic companies. In addition, the value of a Fund's
investments that are denominated in a foreign currency may be affected by
changes in currency exchange rates. For these and other reasons, AIM from time
to time may encounter greater difficulty applying its disciplined stock
selection strategy to an international equity investment portfolio than to a
portfolio of domestic equity securities. See "Risk Factors -- Foreign
Securities."
 
  AGGRESSIVE GROWTH FUND and GROWTH FUND each will normally invest at least 65%
of their respective total assets in marketable equity securities of foreign and
domestic issuers, including common and preferred stock.
 
  AGGRESSIVE GROWTH FUND and GROWTH FUND will each emphasize investment in
companies in developed countries such as the United States, the countries of
Western Europe and certain countries in the Pacific Basin (such as Japan, Hong
Kong and Australia). The Funds may also invest in the securities of companies
located in developing countries (such as Turkey, Poland and Mexico) in various
regions of the world. A "developing country" is a country in the initial stages
of its industrial cycle. Under normal market conditions, the assets of each Fund
will be invested in the securities of companies located in at least four
different countries, including the United States.
 
  Investment in the equity markets of developing countries involves exposure to
securities exchanges 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 than the equity markets of developed
countries. See "Risk Factors -- Emerging Markets and Developing Countries."
 
  AIM GLOBAL INCOME FUND. INCOME FUND'S primary investment objective is to
provide a high level of current income. As a secondary objective the Fund seeks
preservation of principal and capital appreciation. The Fund seeks to achieve
its objectives by investing in a portfolio of U.S. and foreign government and
corporate debt securities. INCOME FUND intends to invest in (i) foreign
government securities, (ii) securities issued by supranational organizations
(such as the World Bank), (iii) foreign and domestic
 
                                       16
<PAGE>   118
 
corporate debt securities, including lower-rated or unrated U.S.
dollar-denominated high yield corporate debt securities, commonly known as "junk
bonds" and (iv) U.S. Government securities, including U.S. Government Agency
mortgage-backed securities.
 
  INCOME FUND is a non-diversified portfolio, which means that with respect to
50% of its assets, it is permitted to invest more than 5% of its assets in the
securities of any one issuer. INCOME FUND will, however, invest no more than 5%
of its total assets in the securities of any one corporate issuer, and will
invest no more than 25% of its total assets in securities of any one foreign
government or supranational issuer. INCOME FUND will generally invest in the
securities of issuers located in at least four countries, including the United
States.
 
  INCOME FUND may invest in securities issued by governments and companies
throughout the world, but expects that it will invest primarily in securities of
issuers in industrialized countries with established securities markets, such as
Western European countries, Canada, Japan, Australia, New Zealand and the United
States. INCOME FUND may, however, invest up to 20% of its total assets in
securities of issuers in developing countries such as Turkey, Poland and Mexico.
 
  Although INCOME FUND will invest at least 65% of its total assets in
non-convertible debt securities of foreign and domestic issuers, it may invest
up to 10% of its total assets in common stocks, preferred stocks and similar
equity securities of foreign and domestic issuers. INCOME FUND may also invest
up to 10% of its total assets in convertible debt securities of foreign and
domestic issuers.
 
  INCOME FUND may invest less than 35% of its total assets in high yield debt
securities (i.e., "junk bonds"). Such securities, at the time of purchase, are
rated below investment grade or are determined by AIM to be of non-investment
grade quality. (For a description of the various rating categories of corporate
debt securities in which INCOME FUND may invest, see Appendix A to this
Prospectus.)
 
  During the fiscal year ended October 31, 1997, the percentage of INCOME FUND'S
average annual assets, calculated on a dollar weighted basis, which was invested
in securities within each rating category of Moody's (as described in Appendix
A), and in unrated securities determined by AIM to be of comparable quality, was
as follows:

  Securities issued by the U.S. Treasury (notes, bonds and bills) are supported
by the full faith and credit of the United States government, while certain
securities issued or guaranteed by agencies or instrumentalities of the U.S.
Government may not be supported by the full faith and credit of the United
States. These agency securities include both obligations supported by the right
of the issuer to borrow from the U.S. Treasury (such as obligations of the
Federal Home Loan Bank) and obligations supported by the credit of the agency or
instrumentality (such as Federal National Mortgage Association bonds.)
Similarly, obligations of foreign governments include obligations issued by
national, provincial, state or other governments that have taxing authority over
their local populations, or by agencies of such governments that may be
supported by the full faith and credit of the governmental entity, or solely by
the credit of such agency.
 
  Supranational organizations include organizations formed and supported by
governmental entities to promote economic growth and development, or
international banking institutions, such as the International Bank for
Reconstruction and Development (the World Bank), the European Coal and Steel
Community, the Asian Development Bank and the Inter-American Development Bank.
Supranational organizations are generally formed and supported by the capital
contributions of governmental entities and, in their lending and other
activities, carry out the particular purposes designated by their member
governmental entities.

  The value of the debt securities in which INCOME FUND invests will change in
response to interest rate changes and other factors. During periods of rising
interest rates, the values of outstanding long-term debt securities will
generally decline, and during periods of falling interest rates, the values of
such securities will generally rise. Such changes will affect the net asset
value per share of INCOME FUND. Longer-term fixed income securities tend to be
subject to greater fluctuations in price than shorter-term securities.
 
  For a discussion of certain risks associated with investments in high yield
securities (i.e., "junk bonds"), foreign securities and non-diversified funds,
see "Risk Factors" in this Prospectus. For a further discussion of the intended
investment strategies of AGGRESSIVE GROWTH FUND, GROWTH FUND and INCOME FUND,
see "Hedging Strategies" and "Other Investment Techniques" in this Prospectus.
 
- --------------------------------------------------------------------------------
 
HEDGING STRATEGIES
 
  Each of the Funds may, at such times as AIM deems appropriate and consistent
with the investment objective of the Fund, write (sell) covered put or call
options on its portfolio securities. Each of the Funds may also purchase and
sell (i) options on domestic and foreign securities and currencies, (ii) stock
index options, (iii) stock, currency and interest rate futures, (iv) options on
stock, currency, stock index and interest rate futures and (v) foreign forward
currency exchange contracts. The purpose of such 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.
 
  OPTIONS. Each Fund may purchase options issued by the Options Clearing
Corporation. Such options give a Fund the right for a fixed period of time to
sell (in the case of purchase of a put option) or to buy (in the case of
purchase of a call option) the number of units of the underlying security or
obligation covered by the option at a fixed or determinable exercise price.
Buying a put option hedges against the risk of a market decline. Buying a call
option hedges against a market advance. Prior to its expiration, a put or call
option may be sold in a closing sale transaction. Gain or loss from such a sale
will depend on whether the amount received is more or less than the premium paid
for the option plus the related transaction costs.
 
  Each Fund also may write (sell) put or 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). A call option is "covered" if a Fund owns the underlying
security covered by the call. A put option is "covered" if a Fund segregates
with its custodian liquid assets with a value equal to the exercise price of the
put option. If a "covered" call or put 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. If the covered put option is exercised,
the writer's cost of purchasing the underlying security is reduced by the amount
of the premium received from the initial sale of the put option. Prior to its
expiration, a put or 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.
 
  Each Fund may also purchase and write options in combination with each other
to adjust the risk and return characteristics of certain portfolio security
positions. This technique is commonly referred to as a "collar."
 
  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 value, 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.
 
  None of the Funds will write options if, immediately after such sale, the
aggregate value of the securities or obligations underlying the outstanding
options exceeds 25% of the Fund's total assets. None of the Funds will purchase
put options (including options on securities indices and futures contracts) if,
at the time of investment, the aggregate premiums paid for such options will
exceed 5% of the Fund's total assets.
 
  FUTURES AND FORWARD CONTRACTS. Since substantially all of the securities held
by each Fund may be denominated in foreign currencies, the value of their
respective portfolios will be affected by changes in exchange rates between
currencies (including the U.S. dollar), as well as by changes in the market
value of the securities themselves. Each Fund may enter into interest rate,
exchange rate and currency futures contracts and related options, or it may
purchase or sell stock index futures contracts and related options in order to
hedge the value of its portfolio against changes in market conditions or in
exchange rates between currencies (including the U.S. dollar). Futures contracts
obligate the seller to deliver a specific type of security called for in the
contract, at a specified future time and for a specified price. Futures
contracts are traded on U.S. and foreign exchanges and generally contain
standardized strike prices and expiration dates. Certain futures contracts may
be satisfied by actual delivery of the securities or, more typically, by
entering into an offsetting transaction. An option on a futures contract gives
the purchaser the right, in return for the premium paid, to assume a position in
a futures contract. In addition to purchasing or selling futures contracts on
currencies and specific securities, interest rates and exchange rates, each Fund
may purchase or sell stock index futures contracts. A stock index futures
contract is an agreement to take or make delivery of an amount of cash based on
the difference between the value of a stock index at the beginning
 
                                       18
<PAGE>   120
 
and at the end of the contract period. No more than 5% of each Fund's total
assets will be committed to initial margin deposits required pursuant to futures
contracts. Percentage investment limitations on each Fund's investment in
options on futures contracts are set forth above under "Options." Although each
Fund is authorized to invest in futures contracts and related options with
respect to foreign securities, stock indices, interest rates and currencies, it
will limit such investments to those which have been approved by the Commodity
Futures Trading Commission for investment by United States investors.
 
  In attempting to manage its currency exposure, each Fund may buy and sell
currencies, either in the spot (cash) market or in the forward market (through
forward contracts generally expiring within one year). Each Fund may also enter
into forward contracts with respect to a specific purchase or sale of a
security, or with respect to its portfolio positions generally. When a Fund
purchases a security for settlement in the near future, it may immediately
purchase in the forward market the currency needed to pay for and settle the
purchase. By entering into a forward contract with respect to the specific
purchase or sale of a security denominated in a foreign currency, a Fund can
secure an exchange rate between the trade and settlement dates for that purchase
or sale transaction. This practice is sometimes referred to as "transaction
hedging." In addition to hedging specific securities transactions, the Funds may
also generally hedge their respective holdings denominated in a particular
currency. This practice is sometimes referred to as "position hedging." The
Funds may not position hedge with respect to the currency of a particular
country to an extent greater than the aggregate market value (at the time of
making such sale) of the securities held in any such Fund's portfolio
denominated or quoted in that particular foreign currency. None of the Funds
will enter into a position hedging commitment if, as a result thereof, (1)
AGGRESSIVE GROWTH FUND or GROWTH FUND would have more than 10% of the value of
their respective total assets committed to such contracts, or (2) INCOME FUND
would have more than 40% of the value of its total assets committed to such
contracts. None of the Funds will enter into a forward contract with a term of
more than one year.
 
  Unlike futures contracts, forward contracts are generally individually
negotiated and privately traded. A forward contract obligates the seller to sell
a specific security or currency at a specified price on a future date, which may
be any fixed number of days from the date of the contract. Each Fund may enter
into transaction hedging forward contracts with respect to all or a substantial
portion of its trades.
 
  There are risks associated with the use of futures and forward contracts and
options thereon for hedging purposes. During certain market conditions, sales of
futures contracts may not completely offset a decline or rise in the value of a
Fund's portfolio securities or currency against which the futures or forward
contract or options thereon are being sold. In the futures and options on
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. Risks in the use of
futures contracts and options thereon also result from the possibility that
changes in the market value of securities or currency may differ substantially
from the changes anticipated by a Fund when hedged positions were established.
Successful use of futures and forward contracts and options thereon is dependent
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. Accordingly, the Funds may lose the expected benefit of
futures and forward transactions and options thereon if markets move in a manner
unanticipated by AIM.
 
- --------------------------------------------------------------------------------
 
OTHER INVESTMENT TECHNIQUES
 
  Each of the Funds has the flexibility to invest, to the extent described
below, in a variety of instruments designed to enhance its investment
capabilities. Each of the Funds may invest in money market obligations, foreign
securities, repurchase agreements, reverse repurchase agreements, illiquid
securities, Rule 144A securities, ADRs and EDRs; INCOME FUND may invest in U.S.
Government Agency Mortgage-Backed Securities; and each of the Funds may purchase
or sell securities on a delayed delivery or when-issued basis, may borrow money,
may lend portfolio securities and make short sales "against the box." A short
sale is "against the box" to the extent that the Fund contemporaneously owns or
has the right to obtain securities identical to those sold short without payment
of any further consideration.
 
  CASH MANAGEMENT AND TEMPORARY DEFENSIVE MEASURES. AIM may invest a portion of
the assets of the Funds in (i) cash or short-term Money Market Obligations, (ii)
U.S. government obligations or investment grade (high quality) corporate bonds
or other debt securities, and (iii) taxable municipal securities, when such
positions are deemed advisable in light of economic or market conditions or for
daily cash management purposes. In addition, AIM may invest, for temporary
defensive purposes, all or substantially all of the assets of the Funds in the
securities described above. The term "Money Market Obligations" includes a broad
range of U.S. Government and foreign government obligations, and bank and
commercial instruments that may be available in the money markets. Examples of
such obligations include U.S. Treasury obligations and repurchase agreements
secured by such obligations, bankers' acceptances, certificates of deposit,
repurchase agreements, time deposits and commercial paper, and U.S. Government
agencies' securities. Money Market Obligations such as bankers' acceptances,
certificates of deposit and time deposits may be purchased from U.S. or foreign
banks. See the Statement of Additional Information for more information on Money
Market Obligations.
 
  To the extent that any of the Funds is invested to a significant degree in
cash or cash equivalent Money Market Obligations, U.S. government obligations or
investment grade (high quality) corporate bonds or other debt securities, or
taxable municipal securities, its ability to achieve its investment objective or
objectives may be adversely affected. Under normal circumstances, neither
AGGRESSIVE GROWTH FUND nor GROWTH FUND will invest more than 35% of the value of
its total assets in high-grade short-term securities,
 
                                       19
<PAGE>   121
 
including repurchase agreements. Under normal circumstances, INCOME FUND will
maintain at least 20% of its total assets in securities of U.S. issuers.
 
  U.S. GOVERNMENT AGENCY MORTGAGE-BACKED SECURITIES. INCOME FUND may invest in
U.S. Government Agency Mortgage-Backed Securities. These securities are
obligations issued or guaranteed by the United States Government or by one of
its agencies or instrumentalities, including but not limited to the Government
National Mortgage Association ("GNMA"), the Federal National Mortgage
Association ("FNMA"), or the Federal Home Loan Mortgage Corporation ("FHLMC").
U.S. Government Agency Mortgage-Backed Certificates provide for the pass-through
to investors of their pro-rata share of monthly payments (including any
principal prepayments) made by the individual borrowers on the pooled mortgage
loans, net of any fees paid to the guarantor of such securities and the
servicers of the underlying mortgage loans. GNMA, FNMA, and FHLMC each guarantee
timely distributions of interest to certificate holders. GNMA and FNMA guarantee
timely distributions of scheduled principal. FHLMC has in the past guaranteed
only the ultimate collection of principal of the underlying mortgage loan;
however, FHLMC Gold Participation Certificates now guarantee timely payment of
monthly principal reductions. Although their close relationship with the U.S.
Government is believed to make them high-quality securities with minimal credit
risks, the U.S. Government is not obligated by law to support either FNMA or
FHLMC. However, historically there have not been any defaults of FNMA or FHLMC
issues. See Appendix B for a more complete description of these securities.
 
  Mortgage-backed securities consist of interests in underlying mortgages
generally with maturities of up to thirty years. However, due to early
unscheduled payments of principal on the underlying mortgages, the securities
have a shorter average life and, therefore, less volatility than a comparable
thirty-year bond. The value of U. S. Government Agency Mortgage-Backed
Securities, like other traditional debt instruments, will tend to decline as
interest rates rise and increase as interest rates decline.
 
  REPURCHASE AGREEMENTS. Each of the Funds may enter into repurchase agreements
with institutions believed by the Company's Board of Directors to present
minimal credit risk. 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. In the event of
a bankruptcy or other default of a seller of a repurchase agreement (such as the
sellers' failure to repurchase the obligation in accordance with the terms of
the 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 reduced levels of income and lack of access to
income during this period; and (d) expenses of enforcing its rights. Repurchase
agreements are considered to be loans by the Fund under the Investment Company
Act of 1940, as amended (the "1940 Act"). Repurchase agreements will be secured
by U.S. Treasury securities, U.S. Government agency securities (including, but
not limited to, those which have been stripped of their interest payments and
mortgage-backed securities) and commercial paper. For additional information on
the use of repurchase agreements, see the Statement of Additional Information.
 
  REVERSE REPURCHASE AGREEMENTS. Each Fund may invest in reverse repurchase
agreements, 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. Each 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 assets having a
dollar value equal to the repurchase price. Reverse repurchase agreements are
considered borrowings by the Fund under the 1940 Act. Reverse repurchase
agreements involve the risk that the market value of securities retained by a
Fund in lieu of liquidation may decline below the repurchase price of the
securities sold by a Fund which it is obligated to repurchase. This risk, if
encountered, could cause a reduction on the net asset value of a Fund's shares.
AGGRESSIVE GROWTH FUND and GROWTH FUND currently intend to enter into reverse
repurchase agreements only for temporary or emergency purposes and not as a
means of increasing income. INCOME FUND may enter into reverse repurchase
agreements to enhance portfolio returns. See "Borrowing."
 
  LENDING OF PORTFOLIO SECURITIES. Each Fund may from time to time lend
securities from their respective portfolios, with a value not exceeding 33 1/3%
of its total assets, to banks, brokers and other financial institutions, and
receive in return collateral in the form of cash or securities issued or
guaranteed by the U.S. Government which will be maintained at all times in an
amount equal to at least 100% of the current market value of the loaned
securities. During the period of the loan, a Fund receives the income on both
the loaned securities and the collateral and thereby increases its yield. In the
event that the borrower defaults on its obligation to return loaned securities
because of insolvency or otherwise, a Fund could experience delays and costs in
gaining access to the collateral and could suffer a loss to the extent that the
value of the collateral falls below the market value of the loaned securities.
 
  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
of 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. Each Fund will only make commitments to purchase
when-issued or delayed delivery securities with the intention of actually
acquiring such securities, but each Fund may sell these securities before the
settlement date if it is
 
                                       20
<PAGE>   122
 
deemed advisable. If a Fund purchases a when-issued security or enters into a
delayed delivery agreement, the Fund's custodian bank will segregate liquid
assets in an amount at least equal to the when-issued commitment or delayed
delivery agreement commitment.
 
  DOLLAR ROLL TRANSACTIONS. In order to enhance portfolio returns and manage
prepayment risks, INCOME FUND may engage in dollar roll transactions with
respect to mortgage securities issued by GNMA, FNMA and FHLMC. In a dollar roll
transaction, a Fund sells a mortgage security held in the portfolio to a
financial institution such as a bank or broker-dealer, and simultaneously agrees
to repurchase a substantially similar security (same type, coupon and maturity)
from the institution at a later date at an agreed upon price. The mortgage
securities that are repurchased will bear the same interest rate as those sold,
but generally will be collateralized by different pools of mortgages with
different prepayment histories. During the period between the sale and
repurchase, the Fund will not be entitled to receive interest and principal
payments on the securities sold. Proceeds of the sale will be invested in
short-term instruments, and the income from these investments, together with any
additional fee income received on the sale, could generate income for the Fund
exceeding the yield on the sold security.
 
  Dollar roll transactions involve the risk that the market value of the
securities retained by a Fund may decline below the price of the securities that
the Fund has sold but is obligated to repurchase under the agreement. In the
event the buyer of securities under a dollar roll transaction files for
bankruptcy or becomes insolvent, the Fund's use of the proceeds from the sale of
the securities may be restricted pending a determination by the other party, or
its trustee or receiver, whether to enforce the Fund's obligation to repurchase
the securities. See "Borrowing," below for the applicable limitation on dollar
roll transactions.
 
  BORROWING. Each of the Funds may borrow money to a limited extent from banks
(including the Funds' custodian bank) for temporary or emergency purposes
subject to the limitations under the 1940 Act. The Funds will restrict
borrowings, reverse repurchase agreements and dollar roll transactions to an
aggregate of 33- 1/3% of each Fund's respective total assets at the time of the
transaction. Neither AGGRESSIVE GROWTH FUND nor GROWTH FUND will purchase
additional securities when any borrowings from banks exceed 5% of each Fund's
respective total assets.
 
  Reverse repurchase agreement transactions and dollar roll transactions are
considered borrowings under the 1940 Act. Any investment gains made by INCOME
FUND with the borrowed 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 by 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."
 
  SHORT SALES. Each Fund may make short sales "against the box." A short sale is
a transaction in which a party sells a security it does not own in anticipation
of a decline in the market value of that security. A short sale is "against the
box" to the extent that a Fund contemporaneously owns or has the right to obtain
securities identical to those sold short without payment of any further
consideration. The Funds will enter into such transactions only to the extent
the aggregate value of all securities sold short does not represent more than
10% of each Fund's respective assets at any given time.
 
  ILLIQUID SECURITIES AND RULE 144A SECURITIES. Each Fund may invest up to 15%
of its net assets in securities that are illiquid. Illiquid securities include
securities that have no readily available market quotations and cannot be
disposed of promptly (within seven days) in the normal course of business at a
price at which they are valued. Illiquid securities may include securities that
are subject to restrictions on resale because they have not been registered
under the Securities Act of 1933. Unregistered securities may, in certain
circumstances, be resold pursuant to Rule 144A, and thus may or may not
constitute illiquid securities. Limitations on the resale of unregistered
securities may have an adverse effect on their marketability, which may prevent
the Fund from disposing of them promptly at reasonable prices. The Fund may have
to bear the expense of registering such securities for resale, and the risk of
substantial delays in effecting such registrations. The Company's Board of
Directors is responsible for developing and establishing guidelines and
procedures for determining the liquidity of Rule 144A securities on behalf of
the Funds and monitoring AIM's implementation of the guidelines and procedures.
 
  INVESTMENT IN OTHER INVESTMENT COMPANIES. Each of the Funds may invest in
other investment companies to the extent permitted by the 1940 Act, and rules
and regulations thereunder, and, if applicable, exemptive orders granted by the
SEC.
 
- --------------------------------------------------------------------------------
 
RISK FACTORS
 
  There can be no assurance that each Fund's investment objective will be
attained. Each Fund is designed for investors seeking international
diversification, and is not intended as a complete investment program. In
addition, investing in securities of foreign companies generally involves
greater risks than investing in securities of domestic companies. INCOME FUND
may also invest in high yield securities (i.e., "junk bonds"), which entail
certain risks. Investors should consider carefully the following special factors
before investing in a Fund.
 
  FOREIGN SECURITIES. The following considerations are risk factors associated
with the Funds' investments in foreign securities:
 
          CURRENCY RISK. The value of a Fund's foreign investments may be
     affected by changes in currency exchange rates. The U.S. dollar value of a
     foreign security generally decreases when the value of the U.S. dollar
     rises against the foreign currency in which the security is denominated,
     and tends to increase when the value of the U.S. dollar falls against such
     currency.
 
                                       21
<PAGE>   123
 
          POLITICAL AND ECONOMIC RISK. The economies of many of the countries in
     which a Fund 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 a
     Fund's investments.
 
          REGULATORY RISK. Foreign companies are generally not subject to the
     regulatory controls imposed on United States issuers and, as a consequence,
     there is generally less public information available about foreign
     securities than is available about domestic securities. Foreign companies
     are not subject to accounting, auditing and financial reporting standards,
     practices and requirements comparable to those applicable to domestic
     companies. Income from foreign securities owned by a Fund may be reduced by
     withholding tax at the source which would reduce dividend income payable to
     the Fund's shareholders.
 
          MARKET RISK. The securities markets in many of the countries in which
     a Fund invests 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. There is generally less government
     regulation and supervision of foreign stock exchanges, brokers and issuers
     which may make it difficult to enforce contractual obligations. 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. Further, the settlement period of securities
     transactions in foreign markets may be longer than in domestic markets.
     These considerations generally are more of a concern in developing
     countries. For example, the possibility of revolution and the dependence on
     foreign economic assistance may be greater in these countries than in
     developed countries. The management of the Funds seeks to mitigate the
     risks associated with these considerations through diversification and
     active professional management.
 
  NON-INVESTMENT GRADE DEBT SECURITIES (INCOME FUND ONLY). INCOME FUND may
invest in non-investment grade debt securities, commonly known as "junk bonds."
While generally providing greater income and opportunity for gain,
non-investment grade debt securities may be subject to greater risks than
higher-rated securities. Economic downturns tend to disrupt the market for junk
bonds and adversely affect their values. Such economic downturns may be expected
to result in increased price volatility for junk bonds and of the value of
shares of the Fund, and increased issuer defaults on junk bonds.
 
  In addition, many issuers of junk bonds are substantially leveraged, which may
impair their ability to meet their obligations. In some cases, junk bonds are
subordinated to the prior payment of senior indebtedness, which potentially
limits a Fund's ability to fully recover principal or to receive payments when
senior securities are subject to a default.
 
  The credit rating of a debt security does not necessarily address its market
value risk, and ratings may from time to time change to reflect developments
regarding the issuer's financial condition. Junk bonds have speculative
characteristics which are likely to increase in number and significance with
each successive lower rating category. Credit ratings evaluate the safety of
principal and interest payments, not market value risk of high yield bonds.
Also, since credit rating agencies may fail to timely change the credit ratings
to reflect subsequent events, AIM continuously monitors the issuers of high
yield bonds in INCOME FUND'S portfolio to determine if the issuers will have
sufficient cash flow and profits to meet required principal and interest
payments, and to attempt to assure the bonds' liquidity so that INCOME FUND can
meet redemption requests. The achievement of INCOME FUND'S investment objective
may be more dependent on AIM's own credit analysis than might be the case for a
fund which invests in higher quality bonds. INCOME FUND may retain a portfolio
security whose rating has been changed. See Appendix A to this
Prospectus -- "Description of Corporate Bond Ratings."
 
  When the secondary market for junk bonds becomes more illiquid, or in the
absence of readily available market quotations for such securities, the relative
lack of reliable objective data makes it more difficult for the directors to
value a Fund's securities, and judgment plays a more important role in
determining such valuations. Increased illiquidity in the junk bond market also
may affect a Fund's ability to dispose of such securities at desirable prices.
 
  In the event a Fund experiences an unexpected level of net redemptions, the
Fund could be forced to sell its junk bonds without regard to their investment
merits, thereby decreasing the asset base upon which the Fund's expenses can be
spread and possibly reducing the Fund's rate of return. Prices of junk bonds
have been found to be less sensitive to fluctuations in interest rates, and more
sensitive to adverse economic changes and individual corporate developments,
than those of higher-rated debt securities.
 
  NON-DIVERSIFIED PORTFOLIO (INCOME FUND ONLY). INCOME FUND is a non-diversified
portfolio, which means that, with respect to 50% of its total assets, it may
invest more than 5% of its assets in obligations of one issuer. (A diversified
portfolio may not invest more than 5% of its assets in obligations of one
issuer, with respect to 75% of its total assets.) Since INCOME FUND may invest a
greater percentage of its assets in securities of fewer issuers than a
diversified portfolio, it may be subject to greater investment and credit risks
than a diversified portfolio.
 
  EMERGING MARKETS AND DEVELOPING COUNTRIES. Investors should also be aware that
the Funds may invest in companies located within emerging or developing
countries. Investments in emerging markets or developing countries involve
exposure to economic structures that are generally less diverse and mature and
to political systems which can be expected to have less stability than those of
more developed countries. Such countries may have relatively unstable
governments, economies based on only a few industries, and securities markets
which trade only a small number of securities. Historical experience indicates
that emerging markets have been more volatile than the markets of more mature
economies; such markets have also from time to time provided higher rates
 
                                       22
<PAGE>   124
 
of return and greater risks to investors. AIM believes that these
characteristics of emerging markets can be expected to continue in the future.
In addition, throughout the countries commonly referred to as the Eastern Bloc,
the lack of a capital market structure or market-oriented economy and the
possible reversal of recent favorable economic, political and social events in
some of those countries present greater risks than those associated with more
developed, market-oriented Western European countries and markets.

INVESTMENT RESTRICTIONS
 
  The following restrictions are matters of fundamental policy and may not be
changed without approval of a Fund's shareholders.
 
  No Fund may:
 
          1. Purchase a security if, as a result, more than 10% of the
     outstanding voting securities of any issuer would be held by the Fund,
     except that the Fund may purchase securities of other investment companies
     to the extent permitted by applicable law or exemptive order.
 
          2. Purchase a security if, as a result, 25% or more of the value of
     the Fund's total assets, taken at market value, would be invested in the
     securities of issuers having their principal business activities in the
     same industry. This restriction does not apply to obligations issued or
     guaranteed by the U.S. Government or by any of its agencies or
     instrumentalities but will apply to foreign government obligations unless
     the SEC permits their exclusion.
 
          3. Borrow money, except that the Fund may borrow from banks (including
     the Fund's custodian bank) and enter into reverse repurchase agreements and
     dollar roll transactions (INCOME FUND only). With respect to AGGRESSIVE
     GROWTH FUND and GROWTH FUND, such permitted borrowings shall be used as a
     temporary defensive measure for extraordinary or emergency purposes.
     Permitted borrowings shall be in amounts not exceeding 33- 1/3% of a Fund's
     total assets, taken at market value, and each Fund may pledge amounts of up
     to 20% of its total assets, taken at market value, to secure such
     borrowings. Whenever bank borrowings exceed 5% of the value of the total
     assets of AGGRESSIVE GROWTH FUND or GROWTH FUND, such Fund will not make
     any additional purchases of securities for investment purposes.
 
  Neither AGGRESSIVE GROWTH FUND nor GROWTH FUND will purchase a security if, as
a result, with respect to 75% of the value of the Fund's respective total
assets, taken at market value, more than 5% of the value of the Fund's total
assets, taken at market value, would be invested in securities of any one
issuer, except securities issued or guaranteed by the U.S. Government or any of
its agencies or instrumentalities and except that the Fund may purchase
securities of other investment companies to the extent permitted by applicable
law or exemptive order.
 
  INCOME FUND will not purchase a security if, as a result, with respect to 50%
of the value of the Fund's total assets taken at market value, more than 5% of
the value of the Fund's total assets, taken at market value, would be invested
in securities of any one issuer, except securities issued or guaranteed by the
U.S. Government or any of its agencies or instrumentalities.
 
  A complete listing of investment restrictions applicable to the Funds, some of
which may be changed by the Board of Directors without shareholder approval, is
contained in the Statement of Additional Information.
 
- --------------------------------------------------------------------------------
 
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. 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 additional
information regarding income taxes and brokerage practices, see the Fund's
Statement of Additional Information.
 
- --------------------------------------------------------------------------------

  Although these fees are higher than those paid by most mutual funds which
invest in domestic securities, they are competitive with such fees paid by
mutual funds which invest primarily in foreign securities. The Company believes
such fees are justified due to the higher costs and additional expenses
associated with managing and operating funds holding primarily foreign
securities.

  In addition, the Company and A I M Fund Services, Inc., P.O. Box 4739,
Houston, TX 77210-4739, a wholly owned subsidiary of AIM and registered transfer
agent, have entered into a Transfer Agency and Service Agreement, pursuant to
which AFS provides transfer agency, dividend distribution and disbursement, and
shareholder services to the Funds.
 
  FEE WAIVERS. AIM may from time to time voluntarily waive or reduce its fees,
while retaining its ability to be reimbursed prior to the end of each fiscal
year. Fee waivers or reductions, other than those contained in the Advisory
Agreement, may be modified or terminated at any time and without notice to
investors. AIM has agreed to waive advisory fees under the Advisory Agreement
for INCOME FUND until such time as in AIM's judgment, the Fund has achieved a
size in assets under management to bear such costs.
 
  DISTRIBUTOR. The Company has entered into Master Distribution Agreements on
behalf of the Funds (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. The address of
A I M Distributors, Inc. is P.O. Box 4739, Houston, Texas 77210-4739. 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 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 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
 
                                       25
<PAGE>   127
 
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 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 0.50% 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 a 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 a 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 a
Fund. The Class A and C Plan does not obligate a 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 a 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, a 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.
 
  Class B Plan. The Company has also adopted a master distribution plan
applicable to Class B shares of each 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 the Class B shares. Of such amount,
each Fund pays a service fee of 0.25% of the average daily net assets
attributable to its 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 such 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 may be used to finance any activity primarily
intended to result in the sale of Class B shares.
 
  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, 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 the 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 the
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 fee that has not been
assigned or transferred, 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 a Fund on an agency basis, may
receive payments from the Fund pursuant to the Fund's Plans. AIM Distributors
does not act as principal, but rather as agent, for the Funds in making such
payments. Financial intermediaries and any other person entitled to receive
compensation for selling Fund shares may receive different compensation for
selling shares of one particular class over another.
 
  For additional information concerning the operation of the Plans, see the
Statement of Additional Information.

ORGANIZATION OF THE COMPANY
 
  The Company was organized in 1991 as a Maryland corporation, and is registered
with the SEC as a diversified open-end series management investment company. The
Company currently consists of six investment portfolios: the Funds, AIM ASIAN
GROWTH FUND, AIM EUROPEAN DEVELOPMENT FUND, and AIM INTERNATIONAL EQUITY FUND.
The Board of Directors may authorize additional portfolios in the future. Shares
of the Funds are offered to investors pursuant to this Prospectus, while shares
of the Company's other portfolios are offered to investors pursuant to separate
prospectuses. The authorized capital stock of the Company consists of
4,000,000,000 shares of common stock with a par value of $0.001 per share, of
which 200,000,000 shares are designated Class A shares, 200,000,000 shares are
designated Class B shares and 200,000,000 shares are designated Class C shares
of each investment portfolio of the Company, and the balance of which are
unclassified.
 
  Class A shares, Class B shares and Class C shares of the same Fund represent
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) and is subject to differing sales
loads (which may affect performance), 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 Class A shares, Class B
shares and Class C shares 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 share-
holders 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.
 
  Under Maryland law and the Company's By-Laws, the Company need not hold an
annual meeting of shareholders unless a meeting is otherwise required under the
1940 Act to elect directors. As of February 2, 1998, Merrill Lynch, Pierce,
Fenner & Smith Incorporated was the owner of record of 26.14% and 46.94% of the
outstanding Class B shares and Class C shares, respectively, of AGGRESSIVE
GROWTH FUND. As of February 2, 1998, Merrill Lynch, Pierce, Fenner & Smith
Incorporated was the owner of record of 36.29% of the outstanding Class C shares
of GROWTH FUND. As long as Merrill Lynch, Pierce, Fenner & Smith Incorporated
owns over 25% of such shares, it may be presumed to be in "control" of the Class
B shares and Class C shares of AGGRESSIVE GROWTH FUND and the Class C shares of
GROWTH FUND, 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.

  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

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

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.

  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) 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
 
   
                                                                       MCF-02/98

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).

EXCHANGE PRIVILEGE
 
  TERMS AND CONDITIONS OF EXCHANGES. Shareholders of the AIM Funds may
participate in an exchange privilege as described below. The exchange privilege
is also available to holders of the Connecticut General Guaranteed Account,
established for tax-qualified group annuities, for contracts purchased on or

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

  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

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

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
ADVISOR REAL ESTATE FUND, by shareholders of record on April 30, 1995 of these
funds (shareholders whose broker/dealers maintain a single omnibus account with
the Transfer Agent on behalf of those shareholders, perform sub-accounting
functions with respect to those shareholders, and are unable to segregate
shareholders of record prior to April 30, 1995 from shareholders whose accounts
were opened after that date will be subject to a CDSC on all purchases made
after March 1, 1996).
 
  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
Code Section 401 (collectively, "Retirement Plans"), (3) 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 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;
 
          (iii) tax-free rollovers or transfers of assets to another Retirement
     Plan invested in Class B or Class C shares of one or more Multiple Class
     Funds;
 
          (iv) tax-free returns of excess contributions or returns of excess
     deferral amounts; and
 
          (v) distributions upon the death or disability (as defined in the
     Code) of the participant or beneficiary.

  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
    
   
                                                                       MCF-02/98

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.
 
  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

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.

  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
any subsequent payment if such notice is received by the Transfer Agent prior to
the record date of such
 
   
                                                                       MCF-02/98
    
   
    
                                      A-18
<PAGE>   147
 
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>   148
 
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.

  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.

  *Aaa -- Bonds which are rated 'Aaa' are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edge." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
 
  *Aa -- Bonds which are rated 'Aa' are judged to be of high quality by all
standards. Together with the 'Aaa' group they comprise what are generally known
as high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in 'Aaa' securities or fluctuation of
protective elements may be of greater amplitude or there may be other elements
present which make the long term risks appear somewhat larger than in 'Aaa'
securities.
 
  *A -- Bonds which are rated 'A' possess many favorable investment attributes
and are to be considered as upper medium grade obligations. Factors giving
security to principal and interest are considered adequate but elements may be
present which suggest a susceptibility to impairment sometime in the future.
 
  *Baa -- Bonds which are rated 'Baa' are considered as medium grade
obligations, i.e., they are neither highly protected nor poorly secured.
Interest payments and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.
 
  Ba -- Bonds which are rated 'Ba' are judged to have speculative elements;
their future cannot be considered as well assured. Often the protection of
interest and principal payments may be very moderate and thereby not well
safeguarded during other good and bad times over the future. Uncertainty of
position characterizes bonds in this class.
 
  B -- Bonds which are rated 'B' generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
  Caa -- Bonds which are rated 'Caa' are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.
 
  Ca -- Bonds which are rated 'Ca' represent obligations which are speculative
in a high degree. Such issues are often in default or have other marked
shortcomings.
 
  C -- Bonds which are rated 'C' are the lowest rated class of bonds and issues
so rated can be regarded as having extremely poor prospects of ever attaining
any real investment standing.
 
NOTE: Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from 'Aa' through 'B' in its corporate bond rating system. The
modifier 1 indicates that the security ranks in the higher end of its generic
rating category; the modifier 2 indicates a mid-range ranking; and the modifier
3 indicates that the issue ranks in the lower end of its generic rating
category.
 
STANDARD AND POOR'S RATINGS SERVICES CLASSIFICATIONS ARE AS FOLLOWS:
 
  *AAA -- Debt rated 'AAA' has the highest rating assigned by Standard & Poor's
("S&P"). Capacity to pay interest and repay principal is extremely strong.
 
  *AA -- Debt rated 'AA' has a very strong capacity to pay interest and repay
principal and differs from the higher rated issues only in small degree.
 
  *A -- Debt rated 'A' has a strong capacity to pay interest and repay principal
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher rated categories.
 
  *BBB -- Debt rated 'BBB' is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher categories.
 
  BB, B, CCC, CC, C -- Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded, on
balance, as predominantly speculative with respect to capacity to pay interest
and repay principal in accordance with the terms of the obligation. 'BB'
indicates the lowest degree of speculation and 'C' the highest degree of
speculation. While such debt will likely have some quality and protective
characteristics, these are outweighed by large uncertainties or major risk
exposures to adverse conditions.
 
                                      A-22
<PAGE>   150
 
  BB -- Debt rated 'BB' has less near-term vulnerability to default than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial, or economic conditions which could lead to
inadequate capacity to meet timely interest and principal payments. The 'BB'
rating category is also used for debt subordinated to senior debt that is
assigned an actual or implied 'BBB-' rating.
 
  B -- Debt rated 'B' has a greater vulnerability to default but currently has
the capacity to meet interest payments and principal repayments. Adverse
business, financial or economic conditions will likely impair capacity or
willingness to pay interest and repay principal. The 'B' rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
'BB' or 'BB-' rating.
 
  CCC -- Debt rated 'CCC' has a currently identifiable vulnerability to default,
and is dependent upon favorable business, financial, and economic conditions to
meet timely payment of interest and repayment of principal. In the event of
adverse business, financial or economic conditions, it is not likely to have the
capacity to pay interest and repay principal. The 'CCC' rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
'B' or 'B-' rating.
 
  CC -- The rating 'CC' is typically applied to debt subordinated to senior debt
that is assigned an actual or implied 'CCC' rating.
 
  C -- The rating 'C' is typically applied to debt subordinated to senior debt
which is assigned an actual or implied 'CCC-' debt rating. The 'C' rating may be
used to cover a situation where a bankruptcy petition has been filed, but debt
service payments are continued.
 
  C1 -- The rating 'C1' is reserved for income bonds on which no interest is
being paid.
 
  D -- Debt rated 'D' is in payment default. The 'D' rating category is used
when interest payments or principal or principal payments are not made on the
date due even if the applicable grace period has not expired, unless S&P
believes that such payments will be made during such grace period. The 'D'
rating also will be used upon the filing of a bankruptcy petition if debt
service payments are jeopardized.
 
  PLUS (+) OR MINUS (-): The rating from 'AA' to 'CCC' may be modified by the
addition of a plus or minus sign to show relative standing within the major
categories.

- --------------------------------------------------------------------------------
 
               DESCRIPTION OF OBLIGATIONS ISSUED OR GUARANTEED BY
                 U.S. GOVERNMENT AGENCIES OR INSTRUMENTALITIES
 
  The following list includes certain common securities, issued or guaranteed by
U.S. Government Agencies or Instrumentalities and does not purport to be
exhaustive.
 
  EXPORT-IMPORT BANK CERTIFICATES -- are certificates of beneficial interest and
participation certificates issued and guaranteed by the Export-Import Bank of
the United States.
 
  FEDERAL FARM CREDIT SYSTEM NOTES AND BONDS -- are bonds issued by a
cooperatively owned, nationwide system of banks and associations supervised by
the Farm Credit Administration, an independent agency of the U.S. Government.
 
  FEDERAL HOME LOAN BANK NOTES AND BONDS -- are notes and bonds issued by the
Federal Home Loan Bank System.
 
  FHA DEBENTURES -- are debentures issued by the Federal Housing Authority of
the U.S. Government.
 
  FHA INSURED NOTES -- are bonds issued by the Farmers Home Administration of
the U.S. Government.
 
  FEDERAL HOME LOAN MORTGAGE CORPORATION ("FHLMC") BONDS -- are bonds issued and
guaranteed by FHLMC, a corporate instrumentality of the U.S. Government. The
Federal Home Loan Banks own all the capital stock of FHLMC, which obtains its
funds by selling mortgages (as well as participation interests in the mortgages)
and by borrowing funds through the issuance of debentures and otherwise.
 
  FHLMC PARTICIPATION CERTIFICATES OR "FREDDIE MACS" -- represent undivided
interests in specified groups of conventional mortgage loans (and/or
participation interests in those loans) underwritten and owned by FHLMC. At
least 95% of the aggregate principal balance of the whole mortgage loans and/or
participations in a group formed by FHLMC typically consists of single-family
mortgage loans, and not more than 5% consists of multi-family loans. FHLMC
Participation Certificates are not guaranteed by, and do not constitute a debt
or obligation of, the U.S. Government or any Federal Home Loan Bank. FHLMC
Participation Certificates are issued in fully registered form only, in original
unpaid principal balances of $25,000, $100,000, $200,000, $500,000, $1 million
and $5 million. FHLMC guarantees to each registered holder of a Participation
Certificate, to the extent of such holder's pro rata share (i) the timely
payment of interest accruing at the applicable certificate rate on the unpaid
principal balance outstanding on the mortgage loans, and (ii) collection of all
principal on the mortgage loans without any offset or deductions. Pursuant to
these guaranties, FHLMC indemnifies holders of Participation Certificates
against any reduction in principal by reason of charges for property repairs,
maintenance, and foreclosure.
 
  FEDERAL NATIONAL MORTGAGE ASSOCIATION ("FNMA") BONDS -- are bonds issued and
guaranteed by FNMA, a federally chartered and privately-owned corporation.
 
  FNMA PASS-THROUGH CERTIFICATES OR "FANNIE MAES" -- are mortgage pass-through
certificates issued and guaranteed by FNMA. FNMA Certificates represent a
fractional undivided ownership interest in a pool of mortgage loans either
provided from FNMA's own portfolio or purchased from primary lenders. The
mortgage loans included in the pool are conventional, insured by the Federal
Housing Administration or guaranteed by the Veterans Administration. FNMA
Certificates are not backed by, nor entitled to, the full faith and credit of
the U.S. Government.
 
  Loans not provided from FNMA's own portfolio are purchased only from primary
lenders that satisfy certain criteria developed by FNMA, including depth of
mortgage origination experience, servicing experience and financial capacity.
FNMA may purchase an entire loan pool from a single lender, and issue
Certificates backed by that loan pool alone, or may package a pool made up of
loans purchased from various lenders.
 
  Various types of mortgage loans, and loans with varying interest rates, may be
included in a single pool, although each pool will consist of mortgage loans
related to one-family or two-to-four family residential properties.
Substantially all FNMA mortgage pools currently consist of fixed interest rate
and growing equity mortgage loans, although FNMA mortgage pools may also consist
of adjustable interest rate mortgage loans or other types of mortgage loans.
Each mortgage loan must conform to FNMA's published requirements or guidelines
with respect to maximum principal amount, loan-to-value ratio, loan term,
underwriting standards and insurance coverage.
 
  All mortgage loans are held by FNMA as trustee pursuant to a trust indenture
for the benefit of Certificate holders. The trust indenture gives FNMA
responsibility for servicing and administering the loans in a pool. FNMA
contracts with the lenders or other servicing institutions to perform all
services and duties customary to the servicing of mortgages, as well as duties
specifically prescribed by FNMA, all under FNMA supervision. FNMA may remove
service providers for cause.
 
  The pass-through rate on FNMA Certificates is the lowest annual interest rate
borne by an underlying mortgage loan in the pool, less a fee to FNMA as
compensation for servicing and for FNMA's guarantee. Lenders servicing the
underlying mortgage loans receive as compensation a portion of the fee paid to
FNMA, the excess yields on pooled loans with coupon rates above the lowest rate
borne by any mortgage loan in the pool and certain other amounts collected, such
as late charges.
 
                                      A-24
<PAGE>   152
 
  The minimum size of a FNMA pool is $1 million of mortgage loans. Registered
holders purchase Certificates in amounts not less than $25,000.
 
  FNMA Certificates are marketed by the servicing lender banks, usually through
securities dealers. The lender of a single lender pool typically markets all
Certificates based on that pool, and lenders of multiple lender pools market
Certificates based on a pro rata interest in the aggregate pool. The amount of
FNMA Certificates currently outstanding is limited.
 
  GOVERNMENT NATIONAL MORTGAGE ASSOCIATION ("GNMA") CERTIFICATES OR "GINNIE
MAES" -- are mortgage-backed securities which represent a partial ownership
interest in a pool of mortgage loans issued by lenders such as mortgage bankers,
commercial banks and savings and loan associations. Each mortgage loan included
in the pool is either insured by the Federal Housing Administration or
guaranteed by the Veterans Administration. A "pool" or group of such mortgages
is assembled, and, after being approved by GNMA, is offered to investors through
securities dealers. GNMA is a U.S. Government corporation within the Department
of Housing and Urban Development.
 
  GNMA Certificates differ from bonds in that the principal is paid back monthly
by the borrower over the term of the loan rather than returned in a lump sum at
maturity. GNMA Certificates are called "modified pass-through" securities
because they entitle the holder to receive its proportionate share of all
interest and principal payments owed on the mortgage pool, net of fees paid to
the issuer and GNMA, regardless of whether or not the mortgagor actually makes
the payment. Payment of principal of and interest on GNMA Certificates of the
"modified pass-through" type is guaranteed by GNMA and backed by the full faith
and credit of the U.S. Government.
 
  The average life of a GNMA Certificate is likely to be substantially less than
the original maturity of the mortgage pools underlying the securities.
Prepayments of principal by mortgagors and mortgage foreclosures will usually
result in the return on the greater part of principal invested far in advance of
the maturity of the mortgages in the pool. Foreclosures impose little risk to
principal investment because of the GNMA guarantee.
 
  As the prepayment rates of individual mortgage pools will vary widely, it is
not possible to accurately predict the average life of a particular issue of
GNMA Certificates. However, statistics published by the Federal Housing
Authority indicate that the average life of a single-family dwelling mortgage
with 25- to 30-year maturity, the type of mortgage which backs the vast majority
of GNMA Certificates, is approximately 12 years. It is therefore customary
practice to treat GNMA Certificates as 30-year mortgage-backed securities which
prepay fully in the twelfth year.
 
  As a consequence of the fees paid to GNMA and the issuer of GNMA Certificates,
the coupon rate of interest of GNMA Certificates is lower than the interest paid
on the VA-guaranteed or FHA-insured mortgages underlying the Certificates.
 
  The yield which will be earned on GNMA Certificates may vary from their coupon
rates for the following reasons: (i) Certificates may be issued at a premium or
discount, rather than at par; (ii) Certificates may trade in the secondary
market at a premium or discount after issuance; (iii) interest is earned and
compounded monthly which has the effect of raising the effective yield earned on
the Certificates; and (iv) the actual yield of each Certificate is affected by
the prepayment of mortgages included in the mortgage pool underlying the
Certificates and the rate at which principal so prepaid is reinvested. In
addition, prepayment of mortgages included in the mortgage pool underlying a
GNMA Certificate purchased at a premium may result in a loss to the Fund.
 
  Due to the large amount of GNMA Certificates outstanding and active
participation in the secondary market by securities dealers and investors, GNMA
Certificates are highly liquid instruments. Prices of GNMA Certificates are
readily available from securities dealers and depend on, among other things, the
level of market rates, the Certificate's coupon rate and the prepayment
experience of the pool of mortgages backing each Certificate.
 
  GENERAL SERVICES ADMINISTRATION ("GSA") PARTICIPATION CERTIFICATES -- are
participation certificates issued by the General Services Administration of the
U.S. Government.
 
  MARITIME ADMINISTRATION BONDS -- are bonds issued and provided by the
Department of Transportation of the U.S. Government.

  PUBLIC HOUSING NOTES AND BONDS -- are short-term project notes and long-term
bonds issued by public housing and urban renewal agencies in connection with
programs administered by the Department of Housing and Urban Development of the
U.S. Government, the payment of which is secured by the U.S. Government.

  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.

  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
shares held by the Transfer Agent in the designated account(s), or in any other
account with any of the AIM Funds, present or future, which has the identical
registration as the designated account(s), with full power of substitution in
the premises. 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
of the shares being redeemed. An investor acknowledges by signing the form that
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
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. 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.
Then any exchanges must be effected in writing by the investor (see the
applicable Fund's prospectus under the caption "Exchange Privilege -- Exchanges
by Mail").

                     AIM INTERNATIONAL EQUITY FUND DISCUSSION AND ANALYSIS
 
    Reproduced below is a discussion of the performance of AIM International
    Equity Fund for the six-month period ended April 30, 1998, that was prepared
    by its officers and A I M Advisors, Inc. and included in its Semiannual
    Report dated April 30, 1998.
 
EUROPEAN MARKETS CONTINUE TO DOMINATE INTERNATIONAL EQUITIES
 
A roundtable discussion with the Fund management team for AIM International
Equity Fund about the six-month reporting period ended April 30, 1998.
 
Q:   HOW DID THE FUND PERFORM DURING THE SIX-MONTH REPORTING PERIOD?
 
A:   The Fund posted another impressive period of performance. Total return was
     17.27% for Class A shares, 16.78% for Class B shares, and 16.84% for Class
     C shares for the six-month period ended April 30, 1998. The Fund's
     performance surpassed both the Morgan Stanley Capital International (MSCI)
     Europe, Australia and Far East Index (EAFE) of foreign stocks gain of
     15.44% during the reporting period and the Lipper International Fund Index
     advance of 16.53%.
 
Q:   WHAT ACCOUNTED FOR THE FUND'S STRONG PERFORMANCE DURING THE PAST SIX
     MONTHS?
 
A:   The impressive performance by European stocks was the story among
     international equities during the past six months. European markets
     continued to rise dramatically as markets there comprised all of the 10
     top-performing international markets during the six-month period ended
     April 30, 1998. Spain led the way with an astounding 54.57% return,
     followed by Portugal with a 52.89% advance. Furthermore, all of the Fund's
     top 10 holdings were European companies. Almost 75% of the Fund's portfolio
     was invested in European equities at the end of the reporting period, a
     figure that is unlikely to increase.
 
Q:   WHY DID EUROPEAN MARKETS PERFORM SO WELL DURING THE REPORTING PERIOD?
 
A:   The European Economic and Monetary Union, or EMU, is scheduled to begin on
     January 1, 1999. In order to qualify for the EMU, European nations must
     adopt strict budgetary guidelines and improve their finances. This process
     has lowered interest rates and kept inflation -- the thief of wealth -- at
     bay. With 11 countries expected to join the EMU next year, this economic
     restructuring has triggered a bull market never before seen in Europe.
 
Q:   WERE THERE ANY OTHER FACTORS DRIVING THE EUROPEAN MARKETS?
 
A:   We believe there were four fundamental, long-term themes that fueled this
     incredible rally in Europe: privatization of state-run companies, increased
     economic freedoms in Eastern Europe, corporate restructuring, and the
     growth of investing in European markets.
 
     Many state-run companies and industries have moved into private hands, such
     as Telecom Italia S.p.A. and Portugal Telecom, two large holdings in the
     Fund's portfolio. Additionally, the economic freedoms in Eastern Europe
     have created a new market of consumers and sparked a wave of
     entrepreneurial efforts in the former Communist Bloc countries. Once
     capitalism is planted it can grow very quickly, and we have seen this since
     the fall of the Berlin Wall. The restructuring by "Corporate Europe" has
     made companies leaner and more globally competitive. We have seen immediate
     results of this restructuring as European earnings growth continued to be
     strong during the reporting period. Finally, thousands of Europeans have
     discovered the wonders of investing in equities. As money has flowed into
     European markets, the markets themselves have become larger and more liquid
     than ever before.
 
Q:   HOW WAS THE FUND'S ASSETS DISTRIBUTED THROUGHOUT THE REST OF THE WORLD?
 
A:   With approximately three-quarters of the Fund now positioned in Europe,
     there's not much else to spread around the globe. The Fund finished the
     reporting period with 7.4% of its net assets in Japan, 4.0% in Asia and
     Australia, and 7.7% in Latin America. These three regions were decimated by
     the "Asian Flu" last fall and have been slow to recover. In the first
     quarter, many of the Asian markets did bounce off their bottoms, some as
     much as 40%, but keep in mind they were coming off very low levels. What
     occurred in the last quarter of 1997 was devastating to those fragile
     emerging markets, and we believe it's going to take quite some time for
     Asia to recover fully from the economic crisis of last autumn.
 
Q:   WHY IS JAPAN IN SUCH AN ECONOMIC MALAISE?
 
A:   Although it seems apparent to the rest of the world that real economic
     reform is needed in Japan, the Japanese government has been extremely
     reluctant to institute any fiscal stimulus or tax cuts to get their economy
     moving. Until the government takes some real action to jump-start the
     economy, there is no
 
                                      IV-1
<PAGE>   157
 
     real reason to be significantly weighted in Japan. We continue to own
     recognizable Japanese companies such as Honda Motor Company and Sony Corp.,
     but the Japanese market has significantly underperformed the rest of the
     world for some time now. The Japanese market was off more than 10% during
     the reporting period.
 
Q:   IN WHICH INDUSTRIES WAS THE FUND POSITIONED?
 
A:   The Fund's largest industry position was major regional banks with almost
     12.5% of net assets. Although one may not think of banking as a growth
     industry, we have seen excellent earnings growth in this industry,
     especially in Europe. Banking positions owned by the Fund included the
     Royal Bank of Canada, Switzerland's Credit Suisse Group, and France's
     Societe Generale.
 
     To no one's surprise during this age of communication breakthroughs, the
     telecommunications sector demonstrated strong earnings during the reporting
     period and commanded over 10% of the Fund's portfolio. The Fund was
     attracted to such wireless telecommunications companies as Finland's Nokia
     Oyj A.B. and Telecom Italia Mobile S.p.A. Finally, automobile companies
     comprised almost 4% of the portfolio with the French automaker Renault S.A.
     having the honor of being the Fund's largest single holding at 1.50% of the
     portfolio's assets.
 
Q:   WHAT IS YOUR OUTLOOK FOR THE FUND IN THE NEAR TERM?
 
A:   We are still very positive on Europe, and very cautious on the Pacific Rim.
     Conditions worldwide remain very good for equities, although it is
     unrealistic to expect continued equity returns of 20% or more. Things may
     continue to worsen in Asia before those markets experience a recovery, so
     we do not anticipate our Asian weightings to increase any time soon. In
     Europe, though, we believe there will continue to be faster earnings growth
     with better valuations than in the United States, because Europe's cash-to-
     price earnings, price-to-book, price-to-dividend, and P/E ratios all are
     lower than in the U.S. The economic outlook in Latin America seems positive
     as well, although the markets there struggled during the six-month
     reporting period.
 
     The economic indicators in the U.S. remain positive, and that is good for
     markets around the world because they often take their lead from the U.S.
     As long as we continue to see the combination of low inflation and low
     interest rates around the globe, the short-term outlook for global equities
     will remain promising.

                 AIM GLOBAL GROWTH FUND DISCUSSION AND ANALYSIS
 
    Reproduced below is a discussion of the performance of AIM Global Growth
    Fund for the six-month period ended April 30, 1998, that was prepared by its
    officers and A I M Advisors, Inc. and included in its Semiannual Report
    dated April 30, 1998.
 
EUROPEAN MARKETS AND U.S. BLUE CHIPS CONTINUE TO DOMINATE WORLD EQUITIES
 
A roundtable discussion with the Fund management team for AIM Global Growth Fund
about the six-month reporting period ended April 30, 1998.
 
Q:   HOW DID THE FUND PERFORM DURING THE SIX-MONTH REPORTING PERIOD?
 
A:   The Fund posted another impressive period of performance. Total return was
     18.81% for Class A shares, 18.49% for Class B shares, and 18.43% for Class
     C shares for the six-month period ended April 30, 1998. The Fund's
     performance was right in line with the Morgan Stanley Capital International
     (MSCI) World Index gain of 18.86% during the reporting period.
 
Q:   WHAT ACCOUNTED FOR THE FUND'S STRONG PERFORMANCE DURING THE PAST SIX
     MONTHS?
 
A:   The impressive performance by European stocks was the story among
     international equities during the past six months. European markets
     continued to rise dramatically as markets there comprised all of the 10
     top-performing international markets during the six-month period ended
     April 30, 1998. Spain led the way with an astounding 54.57% return,
     followed by Portugal with a 52.89% advance. Furthermore, eight of the
     Fund's top 10 holdings were European companies. Almost 43% of the Fund's
     portfolio was invested in European equities at the end of the reporting
     period.
 
     In the United States, the stock market was still feeling the effects of the
     Asian currency crisis during the first three months of the reporting
     period. Markets were slow to recover from a significant drop in October,
     just before the reporting period began, as investors were concerned about
     the impact of the Asian currency devaluations on corporate profits around
     the globe.
 
     However, in the U.S. and most other developed countries, the economic
     fundamentals remained sound. While the economy grew at a brisk pace,
     inflation and interest rates -- two forces that could potentially undermine
     corporate profits continued to be low. In this environment, the Dow Jones
     Industrial Average (DJIA) resumed its upward climb in late January and
     broke the 9000 point mark in April to set a record.
 
Q:   IN THIS ENVIRONMENT, HOW DID LARGE-CAP STOCKS FARE?
 
A:   When markets skyrocketed in the second half of the reporting period,
     large-cap stocks -- particularly the stocks of the very largest companies,
     the so-called "mega caps" -- led the charge. In the uncertain market
     environment created by the Asian currency crises, investors gravitated to
     the stocks of large, well-known companies such as General Electric Co.,
     IBM, and Procter & Gamble Co., which were represented in the Fund's
     portfolio. Additionally, foreign investors were attracted to the equities
     of these large American companies with global reputations. Just over 34% of
     the Fund was positioned in the United States at the end of the reporting
     period.
 
Q:   WHY DID EUROPEAN MARKETS PERFORM SO WELL DURING THE REPORTING PERIOD?
 
A:   The European Economic and Monetary Union, or EMU, is scheduled to begin on
     January 1, 1999. In order to qualify for the EMU, European nations must
     adopt strict budgetary guidelines and improve their finances. This process
     has lowered interest rates and kept inflation -- the thief of wealth -- at
     bay. With 11 countries expected to join the EMU next year, this economic
     restructuring has triggered a bull market unlike any before seen in Europe.

     economic freedoms in Eastern Europe, corporate restructuring, and the
     growth of investing in European markets.

     the fall of the Berlin Wall.

     The restructuring by "Corporate Europe" has made companies leaner and more
     globally competitive. We have seen immediate results of this rest
     restructuring as European earnings growth continued to be strong during the
     reporting period. Finally, thousands of Europeans have discovered the
     wonders of investing in equities. As money has flowed into European
     markets, the markets themselves have become larger and more liquid than
     ever before.
 
Q:   HOW AS THE PORTFOLIO POSITIONED THROUGHOUT THE REST OF THE WORLD?
 
A:   The Fund finished the reporting period with 5.1% of its net assets in
     Japan, 3.2% in Asia and Australia, and 7% in Latin America. These three
     regions were decimated by the "Asian Flu" last fall and have been slow to
     recover. In the first quarter, many of the Asian markets did bounce off
     their bottoms, some as much as 40%, but keep in mind they were coming off
     very low levels. What occurred in the last quarter of 1997 was devastating
     to those fragile emerging markets, and we believe it's going to take quite
     some time for Asia to fully recover from the economic crisis of last
     autumn.
 
Q:   WHY IS THE JAPANESE ECONOMY IN SUCH AN ECONOMIC MALAISE?
 
A:   Although it seems apparent to the rest of the world that real economic
     reform is needed in Japan, the Japanese government has been extremely
     reluctant to institute any fiscal stimulus or tax cuts to get their economy
     out of the economic gutter. Until the government takes some real action to
     jump-start the economy, there is no real reason to be significantly
     weighted in Japan. We continue to own recognizable Japanese companies such
     as Honda Motor Company and Sony Corp., but the Japanese market has
     significantly underperformed the rest of the world for some time now. The
     Japanese market was off more than 10% during the reporting period.

     of net assets. Although one may not think of banking as a growth industry,
     we have seen excellent earnings growth in this industry, we have seen
     excellent earnings growth in this industry, especially in Europe. Banking
     positions owned by the Fund included the Royal Bank of Canada,
     Switzerland's Credit Suisse Group, and France's Societe Generale.
 
     To no one's surprise during this age of technology, the computer software
     and services sector commanded over 5% of the Fund's portfolio. The Fund was
     attracted to such recognizable technology companies as Dell Computer Corp.,
     Compaq Computer Corp., America Online, and Cisco Systems, Inc. Finally,
     automobile companies comprised over 2% of the portfolio with the German
     automaker Volkswagen A.G. having the honor of being the Fund's largest
     single holding at 0.95%.
 
Q:   WHAT IS YOUR OUTLOOK FOR THE FUND IN THE NEAR TERM?
 
A:   We are still very positive on the United States and Europe, and very
     cautious on the Pacific Rim. Conditions worldwide remain very good for
     equities, although it is unrealistic to expect continued equity returns of
     20% or more. Things may continue to worsen in Asia before those markets
