                                                                    July 1, 1999

Dear Shareholder:

     Enclosed is a combined proxy statement and prospectus seeking your approval
of a proposal pursuant to which AIM Eastern Europe Fund ("Eastern Europe Fund")
would convert from a closed-end investment company to an open-end investment
company by reorganizing into AIM Developing Markets Fund ("Developing Markets
Fund"), a series of AIM Investment Funds (the "Trust"), an open-end investment
company (the "Reorganization"). If the proposal is approved and implemented,
each shareholder of Eastern Europe Fund automatically would become a holder of
Class A shares of Developing Markets Fund, and Eastern Europe Fund would
thereafter be liquidated.

     After careful consideration, the Board of Trustees of Eastern Europe Fund
(the "Board") has unanimously approved the proposal and recommends that you read
the enclosed materials carefully and then vote FOR the proposal. As with many
closed-end investment companies, Eastern Europe Fund shares have historically
traded on the New York Stock Exchange at a discount to (i.e., below) the net
asset value of those shares. The Board believes that the Reorganization would
provide Eastern Europe Fund shareholders with the benefits of the open-end
investment company form of organization, while also providing shareholders with
the economies of scale and other benefits of a combination with a larger
existing fund having similar investment objectives but broader investment
policies.

     Eastern Europe Fund's investment objective is long-term capital
appreciation. Developing Markets Fund has a primary investment objective of
long-term growth of capital and a secondary objective of income, to the extent
consistent with seeking growth of capital. To achieve its investment objectives,
Developing Markets Fund invests substantially all of its assets in the
securities of issuers located in developing markets. In contrast, Eastern Europe
Fund invests primarily in securities of issuers located in Eastern Europe. As a
result, Developing Markets Fund possesses greater investment flexibility than
Eastern Europe Fund, because it can and does invest in other regions, including
Latin America, Asia and Africa. The accompanying document describes the proposed
transaction and compares the investment policies, operating expenses, and
performance histories of the Funds in more detail.

     Your vote is important. Please take a moment now to sign and return your
proxy card 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.

                                          Sincerely,
                                          /s/ ROBERT H. GRAHAM

                              Dated: July 1, 1999

     This document is being furnished in connection with the Annual Meeting of
Shareholders of AIM Eastern Europe Fund ("Eastern Europe Fund"), a Massachusetts
business trust, to be held at 11 Greenway Plaza, Suite 100, Houston, TX 77046 on
August 25, 1999 at 3:00 p.m., Central time (such meeting and any adjournments
thereof are referred to as the "Meeting"). At the Meeting, the shareholders of
Eastern Europe Fund are being asked to consider and approve an Agreement and
Plan of Reorganization and Termination ("Plan") that provides for the
reorganization ("Reorganization") of Eastern Europe Fund into AIM Developing
Markets Fund ("Developing Markets Fund"), a series of AIM Investment Funds, a
Delaware business trust ("Trust"). A form of the Plan is attached as Appendix A
to this Combined Proxy Statement and Prospectus ("Proxy Statement/Prospectus").
THE BOARD OF TRUSTEES OF EASTERN EUROPE FUND ("BOARD") HAS UNANIMOUSLY APPROVED
THE PLAN AS BEING IN THE BEST INTEREST OF EASTERN EUROPE FUND.

     Pursuant to the Plan, Eastern Europe Fund will transfer all of its assets
to Developing Markets Fund, which will assume all the liabilities of Eastern
Europe Fund, and the Trust will issue a number of full and fractional Class A
shares of beneficial interest in Developing Markets Fund having an aggregate
value that, on the effective date of the Reorganization, is equal to the
aggregate net asset value of the outstanding shares of beneficial interest in
Eastern Europe Fund. The value of each Eastern Europe Fund shareholder's account
with Developing Markets Fund immediately after the Reorganization will be same
as the net asset value of such shareholder's shares of Eastern Europe Fund
immediately prior to the Reorganization. The Reorganization has been structured
as a tax-free transaction. No initial sales charge will be imposed on Developing
Markets Fund Class A shares issued in connection with the Reorganization. Such
shares will be subject to a 2% fee payable to Developing Markets Fund if they
are presented for redemption within the first year following the Reorganization.

     Developing Markets Fund is a non-diversified series of the Trust, which is
an open-end management investment company comprised of several outstanding
series. Developing Markets Fund's primary investment objective is long-term
growth of capital; its secondary investment objective is income, to the extent
consistent with seeking growth of capital. Developing Markets Fund seeks to
achieve its investment objectives by investing primarily in equity securities of
developing market issuers. Developing Markets Fund may also invest up to 50% of
its total assets in various types of developing market debt securities.

     This Proxy Statement/Prospectus sets forth the information that a
shareholder of Eastern Europe Fund should know before voting on the Plan. It
should be read and retained for future reference.

     A copy of the current Prospectus of Developing Markets Fund, dated March 1,
1999, is attached as Appendix B to this Proxy Statement/Prospectus. In addition,
the management's discussion of the performance of Developing Markets Fund, which
is included in the Annual Report to Shareholders of Developing Markets Fund for
the fiscal year ended October 31, 1998, is attached as Appendix C to this Proxy
Statement/Prospectus. The current Annual Report to Shareholders of Eastern
Europe Fund for the fiscal year ended October 31, 1998 is on file with the
Securities and Exchange Commission (the "SEC") and is incorporated by reference
into this Proxy Statement/Prospectus. In addition, the current Statement of
Additional Information of Developing Markets Fund, dated March 1, 1999, and the
Annual Report to Shareholders of Developing Markets Fund for the fiscal year
ended October 31, 1998 (part of which is attached as Appendix C), are on file

                                  INTRODUCTION

     This Proxy Statement/Prospectus is being furnished to shareholders of
Eastern Europe Fund in connection with the solicitation of proxies by the Board
for use at the Meeting. All properly executed and unrevoked proxies received in
time for the Meeting will be voted in accordance with the instructions contained
therein. If no instructions are given, shares represented by proxies will be
voted FOR all the proposals described in this Proxy Statement/Prospectus and in
accordance with management's recommendation on other matters. The presence in
person or by proxy of Eastern Europe Fund shareholders entitled to cast 50% of
all the votes entitled to be cast at the Meeting will constitute a quorum. If a
quorum is not present at the Meeting or a quorum is present but sufficient votes
to approve any proposal described in this Proxy Statement/ Prospectus are not
received, the persons named as proxies may propose one or more adjournments of
the Meeting to permit further solicitation of proxies. Any such adjournment will
require the affirmative vote of a majority of the shares represented at the
Meeting in person or by proxy. The persons named as proxies will vote those
proxies that they are entitled to vote FOR any proposal in favor of such an
adjournment and will vote those proxies required to be voted AGAINST any
proposal against such adjournment. In addition, if you sign, date, and return
the proxy card, the duly appointed proxies may, in their discretion, vote upon
such other matters as may come before the Meeting.

     The proposal to approve the Plan requires the affirmative vote of a
"majority of the outstanding voting securities" of Eastern Europe Fund, which
for this purpose means the affirmative vote of the lesser of (1) more than 50%
of the outstanding shares of Eastern Europe Fund or (2) 67% or more of the
shares of Eastern Europe Fund present at the meeting if more than 50% of the
outstanding shares of Eastern Europe Fund are represented at the Meeting in
person or by proxy. A plurality of all the votes cast at the Meeting is required
for the election of the Trustee. Ratification of the selection of
PricewaterhouseCoopers LLP as independent accountants for Eastern Europe Fund
requires the affirmative vote of a majority of the votes cast thereon at the
Meeting.

     Abstentions and broker non-votes will be counted as shares present at the
Meeting for quorum purposes, but will not be considered votes cast at the
Meeting. Accordingly, abstentions and broker non-votes are effectively a vote
against a proposal where the required vote is a percentage of the shares present
at the 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 written notice of revocation to the Secretary of Eastern Europe
Fund (the "Secretary"). To be effective, such revocation must be received by the
Secretary prior to the Meeting and must indicate your name and account number.
In addition, although mere attendance at the Meeting will not revoke a proxy, a
registered shareholder present at the 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 Meeting in the discretion of the
proxies or their substitutes.

     Shareholders of record as of the close of business on June 21, 1999 (the
"Record Date"), are entitled to vote at the Meeting. On the Record Date, there
were approximately 5,864,783 shares of Eastern Europe Fund outstanding. Each
share is entitled to one vote for each full share held and a fractional vote for
a fractional share held. Except as set forth under the caption "Ownership of
Eastern Europe Fund and Developing Markets Fund Shares," AIM does not know of
any person who owned beneficially 5% or more of the shares of Eastern Europe
Fund or Developing Markets Fund on the Record Date.

     Eastern Europe Fund has engaged the services of Shareholder Communications
Corporation ("SCC") to assist it in the solicitation of proxies for the Meeting.
Eastern Europe Fund expects to solicit proxies principally by mail, but it or
SCC may also solicit proxies by telephone, facsimile, telegraph, or personal
interview. Eastern Europe Fund officers and employees of A I M Advisors, Inc.
("AIM") who assist in the proxy solicitation will not receive any additional or
special compensation for any such efforts. Each Fund will bear its own expenses
incurred in connection with the Reorganization (including any shareholder
solicitation costs), which are expected to be approximately $70,000 for Eastern
Europe Fund and $15,000 for Developing Markets Fund. However, because Eastern
Europe Fund and Developing Markets Fund currently operate at

                                        1
<PAGE>   8

their respective expense limits, their portion of the Reorganization expenses
will effectively be borne by AIM through reimbursement of expenses and waivers.
Eastern Europe Fund will request broker/dealer firms, custodians, nominees, and
fiduciaries to forward proxy material to the beneficial owners of the shares
held of record by such persons. Eastern Europe Fund may reimburse such
brokers/dealer firms, custodians, nominees, and fiduciaries for their reasonable
expenses incurred in connection with such proxy solicitation.

     Eastern Europe Fund intends to mail this Proxy Statement/Prospectus and the
accompanying proxy on or about July 6, 1999.

                                PROPOSAL NO. 1:
                        REORGANIZATION OF EASTERN EUROPE
                       FUND INTO DEVELOPING MARKETS FUND

                         REASONS FOR THE REORGANIZATION

BOARD CONSIDERATIONS

     The Board, including a majority of trustees who are not "interested
persons" of Eastern Europe Fund, as that term is defined in the Investment
Company Act of 1940 ("1940 Act"), has determined that the Reorganization is in
the best interests of Eastern Europe Fund and that the interests of Eastern
Europe Fund's shareholders will not be diluted as a result of the
Reorganization.

     At a Board meeting held on May 13, 1999, AIM proposed that the Board
approve the reorganization of Eastern Europe Fund into Developing Markets Fund
(each a "Fund"). The Board received from AIM written materials that described
the structure and expected tax consequences of the Reorganization and contained
information concerning both Funds, including comparative total return
information, a comparison of their investment objectives, policies, and risks,
comparative and pro forma expense information, and biographical information on
the portfolio managers of Developing Markets Fund. The Board then made extensive
inquiry into a number of factors with respect to the Reorganization, including:
(1) the compatibility of the Funds' investment objectives, policies, and
restrictions; (2) the Funds' respective investment performance; (3) the effect
of the Reorganization on the expense ratio of Developing Markets Fund Class A
shares and that expense ratio relative to Eastern Europe Fund's current expense
ratio; (4) the costs to be incurred by each Fund as a result of the
Reorganization; (5) the tax consequences of the Reorganization; (6) possible
alternatives to the Reorganization, including continuing to operate Eastern
Europe Fund as a closed-end fund, converting it to an open-end investment
company without reorganizing it into any pre-existing fund, or liquidating it;
and (7) the potential benefits of the Reorganization to other persons,
especially AIM and its affiliates.

     As compared to the available alternatives, the Board determined that
converting Eastern Europe Fund to open-end format by reorganizing it into
Developing Markets Fund was the most advantageous to Eastern Europe Fund. As
with most closed-end funds, shares of Eastern Europe Fund have historically
traded at a discount to net asset value ("NAV"). This discount has persisted
despite conversion of Eastern Europe Fund to "interval fund" status and the
occurrence of repurchase offers at NAV in each of the past four years. While the
Board noted that the closed-end structure offers benefits in terms of portfolio
management, such as the ability to invest without limitation in illiquid
securities and to manage the portfolio without concern to inflows and outflows
of fund assets, continuing to operate Eastern Europe Fund as a closed-end fund
would not address the persistent discount to NAV at which Fund shares have
historically traded. Converting Eastern Europe Fund to open-end format would
eliminate the discount by enabling shareholders to redeem shares at NAV, rather
than selling them in the secondary market. On balance, the Board concluded that
the benefits of the closed-end structure were outweighed by the advantages of
operating as an open-end fund, most notably elimination of the discount to NAV.
Combining the Funds, rather than operating Eastern Europe Fund as a stand-alone
open-end fund, would provide Eastern Europe Fund shareholders with the benefits
of the open-end form of organization, while also providing them with potential
economies of scale and other benefits of a combination with a larger existing
fund having a similar primary investment objective and broader investment
policies. Operating Eastern Europe Fund as a stand-alone open-end fund might not
be economically feasible given its comparatively small asset base, which would
be subject to further reduction by possible net redemptions following conversion
to open-end format.

     Terminating Eastern Europe Fund would result in additional expenses arising
out of liquidating the Fund's portfolio securities and would be a taxable event
to shareholders.

     The Board then considered the investment objectives and policies of the
Funds. Eastern Europe Fund's investment objective is long-term capital
appreciation. Developing Markets Fund has a primary investment objective of
long-term growth of capital and a secondary objective of income, to the extent
consistent with growth of capital. To achieve its investment objectives,
Developing Markets Fund may invest substantially all
                                        3
<PAGE>   10

of its assets in the securities of issuers located in developing markets. In
contrast, Eastern Europe Fund invests at least 65% of its total assets in
securities of issuers located in eastern Europe. As a result, Developing Markets
Fund possesses greater investment flexibility than Eastern Europe Fund. Such
flexibility could, over the long term, benefit shareholders. The Board also
considered the fact that, although Developing Markets Fund has a broader
investment mandate, the Funds' investment objectives and policies are
sufficiently compatible to enable Developing Markets Fund to maintain its
investment policies without any material changes due to the Reorganization. The
Board also noted that Eastern Europe Fund is subject to somewhat greater risk
than Developing Markets Fund because of its narrower geographical focus, but
recognized that Developing Markets Fund is potentially subject to more risk to
the extent that the other countries and regions in which it invests, primarily
in Latin American and Pacific Region countries, have experienced and may
continue to experience substantial economic difficulties. More information on
the risks of investing in developing markets generally, and in Latin America and
Pacific Region countries specifically, is provided below in "Comparison of
Principal Risk Factors -- Investing in Foreign Countries and Developing
Markets."

     The Board also considered the historic performance of Eastern Europe Fund
in relation to the performance of Developing Markets Fund. AIM advised the Board
that, while past performance provides no guarantee of future results, Developing
Markets Fund recently had experienced better investment performance than Eastern
Europe Fund. Information on the relative performance of the Funds is provided
below in "Comparison of the Funds -- Performance."

     The Board also considered the impact the Reorganization would have on
expenses. As a closed-end fund, Eastern Europe Fund currently pays no Rule 12b-1
distribution or service fees. The Developing Markets Fund Class A shares that
Eastern Europe Fund shareholders would receive in the Reorganization are subject
to an annual Rule 12b-1 distribution and service fee of up to 0.50% of average
net assets attributable to Class A. Open-end funds such as Developing Markets
Fund also normally pay higher transfer agency fees than closed-end funds due to
the continuous sale and redemption of their shares. In addition, open-end funds
such as Developing Markets Fund incur expenses associated with maintaining
continuous federal securities registration. Closed-end funds such as Eastern
Europe Fund typically do not incur these expenses.

     In analyzing expenses, the Board also considered the lower investment
advisory and administration fees paid by Developing Market Fund. Eastern Europe
Fund pays total investment advisory and administrative fees of 1.40% of its
average net assets, which includes a voluntary reimbursement by AIM of 0.05% of
average net assets. Developing Markets Fund pays investment advisory and
administration fees of 0.975% on the first $500 million of its average net
assets, 0.95% on the next $500 million of those assets, 0.925% on the next $500
million of those assets, and 0.90% on those assets over $1.5 billion.

     The Board also considered that, overall, the Reorganization may result in
slightly higher total operating expenses for Eastern Europe Fund shareholders.
For its fiscal year ended October 31, 1998, Eastern Europe Fund had total
operating expenses of 1.78% (1.83% before reimbursements) of average weekly net
assets. For its fiscal year ended October 31, 1998, Developing Markets Fund
Class A shares had total operating expenses of 1.93% (2.34% before a contractual
fee cap) of average daily net assets. The Board noted that Developing Markets
Fund's operating expenses included interest expenses of 0.20% of average daily
net assets. The Board was advised by AIM that, during the first six months of
the current fiscal year, those interest expenses had decreased by approximately
0.19%. Accordingly, the Reorganization may result in an increase in total annual
operating expenses for Eastern Europe Fund shareholders, but those expenses may
be slightly lower if interest expenses continue to be lower following the
Reorganization. For more information on the comparative fees and expenses of
Developing Markets Fund and Eastern Europe Fund, see "Comparison of the
Funds -- Fees and Expenses," below.

     The Board noted that no initial sales charges would be imposed on the
Developing Markets Fund Class A shares issued to Eastern Europe Fund
shareholders in connection with the Reorganization. However, those shares will
be subject to a redemption fee equal to 2% of the NAV of the shares being
redeemed, which would apply to redemptions made during the first year following
the Reorganization. The fee would be payable to Developing Markets Fund. The
Board approved the temporary imposition of this redemption fee as reasonable in
light of Developing Markets Fund's anticipated expenses in connection with
post-Reorganization redemp-

                                        4
<PAGE>   11

tions of those shares. These expenses include brokerage and other costs of
selling portfolio securities to raise cash for redemption requests and transfer
agency and other administrative expenses caused by redeeming shareholders. The
redemption fee will decrease the likelihood that these expenses would be borne
by present Developing Markets Fund shareholders. The Board also noted that
imposition of the redemption fee may deter some redemptions of Developing
Markets Fund Class A shares immediately following the Reorganization,
particularly with respect to investors who purchased Eastern Europe Fund shares
just prior to the Reorganization. In this regard, the Board considered the
detrimental effect that such short-term trading would have on Developing Markets
Fund.

     The Board also considered that, although AIM will effectively bear
Developing Markets Fund's portion of the Reorganization-related expenses, it may
also receive an indirect benefit from the Reorganization. To the extent that
Developing Markets Fund's operating expenses decrease as a result of the
Reorganization, there could be a reduction in payment by AIM to cover its
reimbursement obligation to limit the expenses of Developing Markets Fund Class
A shares to 2.00% of average net assets. Further, the obligation of AIM to
reimburse the expenses of Eastern Europe Fund will terminate with the close of
the Reorganization.

     Finally, the Board reviewed the principal terms of the Plan and noted that
Eastern Europe Fund would be provided with an opinion of counsel that the
Reorganization would be tax-free to it and its shareholders.

     On the basis of the information provided to the Board and on its evaluation
of that information, the Board determined that the proposed Reorganization will
not dilute the interests of shareholders of Eastern Europe Fund and is in the
best interest of Eastern Europe Fund. Therefore, the Board recommended the
approval of the Plan by the shareholders of Eastern Europe Fund at the Meeting.

                                    SYNOPSIS

THE REORGANIZATION

     The Plan provides for the acquisition by Developing Markets Fund of all of
Eastern Europe Fund's assets in exchange solely for Developing Markets Fund
Class A shares and the assumption by Developing Markets Fund of all of Eastern
Europe Fund's liabilities. Those transactions will occur at 4:00 p.m., Central
time, on August 27, 1999, or on such later date as the conditions to the closing
are satisfied ("Closing Date"). Eastern Europe Fund will then distribute the
Developing Markets Fund Class A shares to its shareholders so that each Eastern
Europe Fund shareholder will receive full and fractional Developing Markets Fund
Class A shares equal in aggregate value to the NAV of the shareholder's shares
of Eastern Europe Fund as of the Closing Date. Eastern Europe Fund will be
liquidated as soon as is practicable thereafter.

     Eastern Europe Fund and the Trust will receive an opinion of Kirkpatrick &
Lockhart LLP, their counsel, to the effect that the Reorganization will
constitute a tax-free reorganization within the meaning of section 368(a)(1)(C)
of the Internal Revenue Code of 1986, as amended ("Code"). Accordingly, neither
Fund nor any of their shareholders will recognize any gain or loss as a result
of the Reorganization. See "Additional Information About the
Reorganization -- Federal Income Tax Considerations," below.

COMPARISON OF THE FUNDS

Forms of Organization

     Developing Markets Fund is an open-end fund organized as a series of the
Trust, a Delaware business trust, whose shares are continuously sold and
redeemed at NAV. Eastern Europe Fund is a closed-end "interval" fund organized
as a Massachusetts business trust whose shares are traded on the New York Stock
Exchange ("NYSE") and are subject to annual repurchase offers pursuant to Rule
23c-3 under the 1940 Act. Open-end funds such as Developing Markets Fund
continuously offer and redeem their shares, causing their total assets to
fluctuate. In contrast, most closed-end funds make a single offering of
non-redeemable shares and thus retain a stable pool of assets, which changes
only upon appreciation or depreciation of their portfolio investments.
Closed-end interval funds, like Eastern Europe Fund, conduct periodic repurchase
offers, which

                                        5
<PAGE>   12

result in some fluctuation in their assets, although generally less than that
experienced by open-end funds like Developing Markets Fund.

Investment Objectives

     The investment objectives of Developing Markets Fund and Eastern Europe
Fund are similar. Developing Markets Fund's primary investment objective is
long-term growth of capital. Its secondary investment objective is income, to
the extent consistent with seeking growth of capital. Eastern Europe Fund's
investment objective is long-term capital appreciation.

Investment Policies

     As described below, the primary difference in the investment policies of
Developing Markets Fund and Eastern Europe Fund is the geographic focus of their
investments. Developing Markets Fund invests in issuers in developing markets in
Asia, Europe, Latin America, and elsewhere. Eastern Europe Fund, in contrast,
invests primarily in issuers located in Eastern Europe.

     Developing Markets Fund seeks its investment objectives by investing,
normally, substantially all of its assets in equity and debt securities of
issuers located in developing markets. A majority of the Developing Markets
Fund's assets ordinarily is invested in developing market equity securities.
Developing Markets Fund may invest up to 50% of its assets in developing market
debt securities, which are selected based on their potential to provide a
combination of capital appreciation and/or current income. There is no limit on
the percentage of assets that Developing Markets Fund may invest in
non-investment grade debt securities.

     Eastern Europe Fund seeks its objective by investing, normally, at least
65% of its total assets in equity and debt securities of issuers (including
government issuers) located in Eastern Europe. "Eastern European" countries
include Albania, Bulgaria, the Czech Republic, Germany, Hungary, Poland,
Romania, Slovakia, all countries west of the Ural Mountains that were formerly a
part of the USSR (including Russia, Belarus, Estonia, Latvia, Lithuania, and the
Ukraine), and all countries that formerly constituted Yugoslavia. Eastern Europe
Fund normally invests at least 50% of its total assets in the developing markets
of Eastern Europe, which includes all of the countries listed above except
Germany. In addition, Eastern Europe Fund may invest up to 35% of its total
assets in equity and debt securities of issuers (including government issuers)
located elsewhere in Europe, most of which are developed countries. There is no
limit on the percentage of assets that Eastern Europe Fund may invest in
non-investment grade debt securities.

Portfolio Management

     Closed-end interval funds such as Eastern Europe Fund generally have
greater freedom in managing their portfolios than open-end funds like Developing
Markets Fund. Because closed-end interval funds are not subject to forced sale
of portfolio securities at undesirable times or prices to meet redemption
requests (except to the extent that securities must be sold to meet the demands
of periodic repurchase offers), they have more freedom to invest in illiquid
securities and may keep a larger percentage of their assets fully invested in
equity or debt securities, rather than in cash. In addition, closed-end funds
have greater flexibility under the 1940 Act to leverage their portfolios by
borrowing. Despite having greater flexibility in portfolio management, Eastern
Europe Fund has generally not engaged in such leveraging. Moreover, as of April
30, 1999, only about 14% of Eastern Europe Fund's assets were invested in
illiquid securities.

Expense Example

     The example is intended to help you compare the costs of investing in Class
A shares of Developing Markets Fund, both before and after the Reorganization,
with the costs of investing in shares of Eastern Europe Fund.

     The example assumes that you invest $10,000 in each Fund for the time
periods indicated. The example also assumes that your investments each have 5%
return each year and that each Fund's operating expenses remain the same. To the
extent fees are waived, the expenses will be lower. Although your actual returns
and costs may be higher or lower, based on these assumptions your costs would
be:

</TABLE>

Sales Charges

     Developing Markets Fund Class A shares received in connection with the
Reorganization are not subject to the customary initial sales charge of 4.75%.
However, those shares will be subject to a 2% redemption fee for the first year
following the Reorganization. Shares received in connection with the
Reorganization and exchanged for shares in other AIM Funds will be subject to
the 2% redemption fee upon the exchange. Any new purchases of Developing Markets
Fund Class A shares will be subject to the initial sales charge but not the
redemption fee.

Distribution, Purchase, Exchange, and Redemption

     Shares of Developing Markets Fund are available through A I M Fund
Services, Inc. ("Transfer Agent") or through any dealer authorized by A I M
Distributors, Inc. ("AIM Distributors") to sell shares of the AIM Funds. The
minimum initial investment in Developing Markets Fund is $500; each additional
investment must be $50 or more. These minimums may be waived or reduced for
investments by employees of AIM or its affiliates, certain pension plans and
retirement accounts, and participants in an AIM Fund's automatic investment
plan.

     Developing Markets Fund Class A shares pay a fee in the amount of up to
0.50% of average daily net assets to AIM Distributors for distribution and
shareholder services pursuant to a Rule 12b-1 plan (the "12b-1 fee"). As noted
above, Developing Markets Fund Class A shares are generally subject to an
initial sales charge of 4.75%. Shares of Developing Markets Fund may be
exchanged for shares of other AIM Funds of the corresponding class and may be
acquired through exchange of the corresponding Class of shares of other AIM
Funds, as described in Developing Markets Fund's prospectus. No initial sales
charge is imposed on the shares acquired through an exchange. Exchanges are
subject to minimum investment and other requirements of the AIM Fund into which
exchanges are made. Developing Markets Fund Class A shares may be redeemed by
the Fund at NAV and are generally not subject to a CDSC.

     Shares of Eastern Europe Fund are listed and publicly traded on the NYSE
under the symbol "GTF" and are not subject to distribution fees. The Developing
Markets Fund Class A shares that would be issued to Eastern Europe Fund
shareholders in connection with the Reorganization are subject to the 12b-1 fee.
Eastern Europe Fund shares were issued in a public offering completed on March
29, 1990. Shareholders of Eastern Europe Fund currently do not have an exchange
privilege. Upon completion of the Reorganization, however, former Eastern Europe
Fund shareholders would hold Developing Markets Fund Class A shares and would
enjoy the same exchange privileges as other Developing Markets Fund Class A
shareholders, although such exchanges would be subject to the one-year
redemption fee described above. Although Eastern Europe Fund shares are
non-redeemable, shareholders of Eastern Europe Fund may sell their shares on the
NYSE or participate in one of the Fund's annual repurchase offers. As noted
above, the Developing Markets Fund

                                        9
<PAGE>   16

Class A shares received by Eastern Europe Fund shareholders in the
Reorganization will be subject to a redemption fee in certain circumstances.

Operations of Developing Markets Fund Following the Reorganization

     Although there are differences in the investment objectives and policies of
the Funds, it is not expected that Developing Markets Fund will revise its
investment objectives or any of its policies following the Reorganization to
reflect those of Eastern Europe Fund. Rather, because Eastern Europe Fund's
assets are predominantly equity securities of Eastern European issuers, all of
which are consistent with Developing Markets Fund's investment policies, AIM and
IAML, Eastern Europe Fund's investment advisor and sub-advisor, respectively,
believe that substantially all of Eastern Europe Fund's assets could be
transferred to and held by Developing Markets Fund if the Reorganization is
approved. Upon such approval of the Reorganization, Eastern Europe Fund will
sell any assets that are inconsistent with Developing Markets Fund's investment
policies prior to the effective time of the Reorganization, and the proceeds
thereof will be held in temporary investments or reinvested in assets that
qualify to be held by Developing Markets Fund. The need, if any, for Eastern
Europe Fund to dispose of assets prior to the effective time of the
Reorganization may result in selling securities at a disadvantageous time and
could result in Eastern Europe Fund's realizing gains or losses that would not
otherwise have been realized.

Investment Advisors and Portfolio Management

     AIM serves as investment advisor, and INVESCO Asset Management Limited
("IAML") serves as investment sub-advisor, to both Eastern Europe Fund and
Developing Markets Fund. AIM and IAML use a team approach to managing the Funds'
respective investment portfolios. The individual members of the team who are
responsible for the day-to-day management of Eastern Europe Fund's portfolio
are:

       of the INVESCO Central and Eastern Europe Asset Management Group
       specializing in Eastern Europe.

     - Jonathan Brock, Portfolio Manager for Eastern Europe Fund since 1998 and
       a Senior Investment Manager with IAML since 1994. Also since 1994, he has

                      COMPARISON OF PRINCIPAL RISK FACTORS

PRIMARY DIFFERENCES IN RISKS OF THE FUNDS

     Developing Markets Fund and Eastern Europe Fund are subject to
substantially the same investment risks arising out of investing in foreign
securities generally and developing markets specifically. However, Eastern
Europe Fund is subject to additional risk arising out of its narrower geographic
focus. Eastern Europe Fund focuses its investments in a small number of
countries, many of which are either involved in, or may be affected by, the
current instability in that region. By contrast, Developing Markets Fund may
invest in developing markets around the world, and thus has greater latitude to
limit its investments in countries that are undergoing political or economic
upheaval. On the other hand, some of the non-European countries and regions in
which Developing Markets Fund invests, such as Latin America and the Pacific
Region, have recently experienced substantial economic difficulties.

     Investments in Latin American countries involve special risks. Most Latin
American countries have experienced substantial, and in some periods extremely
high, rates of inflation for many years, which have had, and may continue to
have, very negative effects on the economies and securities markets of Latin
American countries. Certain Latin American countries are among the largest
debtors to commercial banks and foreign governments. At times, some of these
countries have suspended payments of principal and/or interest on external debt.
Some Latin American securities markets have experienced high volatility in
recent years. Latin American countries may close certain sectors of their
economies to equity investments by foreigners. Due to these and other
restrictions on direct investment by foreign entities, and to the absence of
securities markets and publicly owned corporations in certain Latin American
countries, investments may be made solely or primarily through governmentally
approved investment vehicles or companies. Certain Latin American countries may
have managed currencies that are maintained at artificially high levels to the
U.S. dollar rather than at market determined levels. This type of system can
lead to sudden and large adjustments in the currency which, in turn, can have a
disruptive and negative effect on foreign investors. For example, in late 1994,
the value of the Mexican peso lost more than one-third of its value relative to
the U.S. dollar.

     Certain of the risks associated with international investments are
heightened for investments in Pacific Region countries. For example, some of the
currencies of Pacific Region countries have experienced steady devaluations
relative to the U.S. dollar, and major adjustments have been made periodically
in certain of such currencies. Certain countries, such as India, face serious
currency exchange constraints. Territorial disputes exist between North Korea
and South Korea. Developing Markets Fund may invest in Hong Kong, which reverted
to Chinese administration on July 1, 1997. Investments in Hong Kong may be
subject to expropriation, nationalization, or confiscation, in which case
Developing Markets Fund could lose its entire investment in Hong Kong. In
addition, reversion of Hong Kong also presents a risk that the Hong Kong dollar
will be devalued and a risk of possible loss of investor confidence in Hong
Kong's currency, stock market, and assets.

RISKS COMMON TO BOTH FUNDS

Investing in Securities Generally

     Investing in either Developing Markets Fund or Eastern Europe Fund entails
a risk that you could lose all or a portion of your investment. The value of
your investment in either Fund goes up and down with the prices of the
securities in which the Fund invests. The prices of equity securities change in
response to many factors, including the historical and prospective earnings of
the issuer, the value of its assets, general economic conditions, interest
rates, investor perceptions, and market liquidity. Debt securities are
particularly vulnerable to credit risk and interest rate fluctuations. When
interest rates rise, bond prices fall; the longer the bond's duration, the more
sensitive it is to this risk.

Investing in Foreign Securities and Developing Markets

     Investments in foreign securities may be affected by, among others, the
following factors:

     - Currency exchange rates -- The dollar value of the Funds' foreign
       investments will be affected by changes in the exchange rates between the
       dollar and the currencies in which those investments are traded.

     - Political and economic conditions -- The value of the Funds' foreign
       investments may be adversely affected by political and social instability
       in their home countries and by changes in economic or taxation policies
       in those countries.

     - Regulations -- Foreign companies generally are subject to less stringent
       regulations, including financial and accounting controls, than are U.S.
       companies. As a result, there generally is less publicly available
       information about foreign companies than about U.S. companies.

     - Markets -- The securities markets of other countries are smaller than
       U.S. securities markets. As a result, many foreign securities may be less
       liquid and their prices may be more volatile than U.S. securities.

     These factors may affect the prices of securities issued by foreign
companies located in developing countries more than those in countries with
mature economies. For example, many developing countries have, in the past,
experienced high rates of inflation or sharply devalued their currencies against
the U.S. dollar, thereby causing the value of investments in companies located
in those countries to decline. Transaction costs are often higher in developing
countries and there may be delays in settlement procedures.

Lower Quality Debt

     Both Developing Markets Fund and Eastern Europe Fund may invest up to 100%
of their respective total assets in debt securities rated below investment grade
or, if unrated, deemed by AIM or IAML to be of comparable quality ("junk
bonds"). Compared to higher-quality debt securities, junk bonds involve greater
risk of default or price changes due to changes in the credit quality of the
issuer because they are generally unsecured and may be subordinated to other
creditors' claims. The value of junk bonds often fluctuates in response to
issuer, political, or economic developments and can decline significantly over
short periods of time or during periods of general or regional economic
difficulty. During those times, the bonds may be difficult to value or sell at a
fair price. Credit ratings on junk bonds do not necessarily reflect their actual
market risk.

Sovereign Debt

     Both Developing Markets Fund and Eastern Europe Fund may invest in
sovereign debt securities of developing country governments, including Brady
Bonds. Brady Bonds are debt restructurings that provide for the exchange of cash
and loans for newly issued bonds. Investments in sovereign debt securities of
developing countries involve special risks. Sovereign debt securities of
developing countries are generally lower-quality debt securities, equivalent to
junk bonds. Accordingly, they are subject to many of the same risks as junk
bonds, detailed above. In addition, sovereign debt securities are subject to the
risk that, under certain political, diplomatic, social, or economic
circumstances, some developing countries that issue sovereign debt securities
may be unable or unwilling to make principal or interest payments as they come
due.

Illiquid Securities

     Developing Markets Fund may invest up to 15% of its net assets in illiquid
securities. Eastern Europe Fund may invest without restriction (consistent with
its obligation to maintain adequate liquidity to satisfy its annual repurchase
offers) in certain restricted or otherwise illiquid securities. Any limitations
on resale and marketability of such securities may have the effect of preventing
the Funds from disposing of such securities at the time desired or at a
reasonable price. In addition, in order to resell restricted securities, the
Funds might have to bear the expense and incur the delays associated with
registering such securities.

                                       12
<PAGE>   19

Non-Diversified Classification

     Both Developing Markets Fund and Eastern Europe Fund are classified under
the 1940 Act as "non-diversified" funds. Non-diversified funds may invest in
fewer issuers than diversified funds. As a result, each Fund may be subject to
greater investment and credit risk, than if it invested more broadly.

Year 2000

     The value of shares in both Developing Markets Fund and Eastern Europe Fund
could be adversely affected if the computer systems used by the Funds'
investment advisors or other service providers are unable to distinguish the
year 2000 from the year 1900.

     The Funds' investment advisors and independent technology consultants are
working to avoid Year 2000-related problems in their systems and to obtain
assurances that other service providers are taking similar steps.

     Year 2000 problems may also affect issuers in whose securities the Funds
invest. AIM considers the Year 2000 preparedness of the companies in which the
Funds invest as one factor among many in deciding whether to purchase or sell a
security.

                              FINANCIAL HIGHLIGHTS

     On October 31, 1997, Developing Markets Fund, which had no previous
operating history, acquired the assets and assumed the liabilities of G.T.
Global Developing Markets Fund, Inc. (the "Predecessor Fund"), a closed-end
investment company whose single class of shares traded on the NYSE. The fees and
expenses of Developing Markets Fund differ from those of the Predecessor Fund.
Developing Markets Fund's fiscal year ends October 31, rather than December 31,
which was the Predecessor Fund's fiscal year-end.

                ADDITIONAL INFORMATION ABOUT THE REORGANIZATION

TERMS OF THE REORGANIZATION

     The terms and conditions under which the Reorganization may be consummated
are set forth in the Plan. Significant provisions of the Plan are summarized
below; however, this summary is qualified in its entirety by reference to the
Plan, a form of which is attached as Appendix A to this Proxy
Statement/Prospectus.

     The Plan contemplates (a) Developing Markets Fund acquiring on the Closing
Date all the assets of Eastern Europe Fund in exchange solely for Developing
Markets Fund Class A shares and Developing Markets Fund's assumption of all of
Eastern Europe Fund's liabilities and (b) the distribution of those shares to
Eastern Europe Fund shareholders. Eastern Europe Fund's assets include all cash,
cash equivalents, securities, receivables (including interest and dividends
receivable), claims and rights of action, rights to register shares under
applicable securities laws, books and records, deferred and prepaid expenses
shown as assets on its books, and other property owned by it as of the close of
regular trading on the NYSE on the Closing Date ("Valuation Time")
(collectively, the "Assets"). Developing Markets Fund will assume from Eastern
Europe Fund all its liabilities, debts, obligations, and duties of whatever kind
or nature, whether absolute, accrued, contingent, or otherwise, whether or not
arising in the ordinary course of business, whether or not determinable at the
Valuation Time, and whether or not referred to in the Plan (collectively, the
"Liabilities"); provided, however, that Eastern Europe Fund will use its best
efforts to discharge all of its known Liabilities prior to the Valuation Time.
Developing Markets Fund will deliver its Class A shares to Eastern Europe Fund,
which then will be distributed to Eastern Europe Fund's shareholders.

     The value of the Assets to be acquired, and the amount of the Liabilities
to be assumed, by Developing Markets Fund and the NAV of a Class A share of
Developing Markets Fund will be determined as of the Valuation Time. Where
market quotations are readily available, portfolio securities will be valued
based upon the quotations, provided they adequately reflect, in AIM's judgment,
the fair value of the security. Where market quotations are not readily
available, securities will be valued based upon appraisals received from a
pricing service using a computerized matrix system or appraisals derived from
information concerning the security or similar securities received from
recognized dealers in those securities. The amortized cost method of valuation
generally will be used to value debt instruments with 60 days or less remaining
to maturity, unless a Fund's Board of Trustees determines that this method does
not represent fair value. All other securities and assets will be valued at fair
value as determined in good faith by or under the direction of each Fund's Board
of Trustees.

     On, or as soon as practicable after, the Closing Date, Eastern Europe Fund
will distribute to its shareholders of record the Developing Markets Fund Class
A shares it receives so that each Eastern Europe Fund shareholder will receive a
number of full and fractional Class A shares of Developing Markets Fund equal in
aggregate NAV to the shareholder's shares in Eastern Europe Fund. Such
distribution will be accomplished by opening accounts on the books of Developing
Markets Fund in the names of Eastern Europe Fund's shareholders and crediting
such accounts with Developing Markets Fund Class A shares equal in aggregate NAV
to the shareholders' shares in Eastern Europe Fund. Fractional shares of
Developing Markets Fund will be rounded to the third decimal place.

     Immediately after the Reorganization, each former shareholder of Eastern
Europe Fund will own Class A shares of Developing Markets Fund equal in NAV to
the aggregate NAV of that shareholder's shares in Eastern Europe Fund
immediately prior to the Reorganization. The NAV per share of Developing Markets
Fund will not be changed as a result of the Reorganization. Thus, the
Reorganization will not result in a dilution of any shareholder interest.

DESCRIPTION OF SECURITIES TO BE ISSUED

     The Trust is registered with the SEC as an open-end management investment
company. Pursuant to the Trust's Agreement and Declaration of Trust, the Trust
may issue an unlimited number of shares. The Trust's Board of Trustees (the
"Trust's Board") has established Developing Markets Fund as a series of the
Trust and has authorized the public offering of four classes of shares of that
Fund, designated Class A, Class B, Class C,
                                       16
<PAGE>   23

and Advisor Class shares. Only Class A shares will be issued in connection with
the Reorganization. Although Class A shares are generally subject to an initial
sales charge of 4.75%, this sales charge will be waived for the shares issued in
connection with the Reorganization. As noted above, those shares will be subject
to a 2% redemption fee for the first year following the Reorganization.

     Each share of Developing Markets Fund represents an equal proportionate
interest with other shares in that Fund, has a par value of $0.01 per share, has
equal earnings, assets, and voting privileges, except as noted in the Developing
Markets Fund Statement of Additional Information, and is entitled to such
dividends and other distributions out of the income earned and gain realized on
the assets belonging to the Fund as may be declared by the Trust's Board. Each
share in a class represents an equal proportionate interest in Developing
Markets Fund's assets with each other share in that class. Shares of Developing
Markets Fund entitle their holders to one vote per full share and fractional
votes for fractional shares held, except that each Class has exclusive voting
rights on matters pertaining to its plan of distribution. Shares of Developing
Markets Fund, when issued, are fully paid and nonassessable.

DIVIDENDS AND OTHER DISTRIBUTIONS

     Dividends from Developing Markets Fund's net investment income, if any, are
distributed at least annually. Any net capital gain (the excess of net long-term
capital gain over net short-term capital loss) and net short-term capital gain
realized from the sale of portfolio securities and net gains from foreign
currency transactions are also distributed at least annually. Shareholders of
Developing Markets Fund may reinvest dividends and other distributions in
additional Fund shares of the distributing class (or in shares of the
corresponding class of other AIM Funds) on the payment date at those shares' NAV
that day or receive the distribution amount in cash.

     Dividends from Eastern Europe Fund's net investment income, if any, are
distributed at least annually. Any net capital gain and net short-term capital
gain realized from the sale of portfolio securities and net gains from foreign
currency transactions are also distributed at least annually. Shareholders of
Eastern Europe Fund may participate in the Fund's Dividend Reinvestment Plan,
under which dividends and capital gains distributions are automatically invested
in additional shares of the Fund at NAV. Alternatively, shareholders may elect
to receive dividends and other distributions in cash.

     Each Fund may make additional distributions if necessary to avoid a 4%
excise tax on certain undistributed ordinary income and capital gains.

     On or before the Closing Date, Eastern Europe Fund will declare as a
distribution substantially all of its undistributed net investment income, net
capital gain, net short-term capital gain, and net gains from foreign currency
transactions to maintain its tax status as a regulated investment company.

     The consummation of the Reorganization is subject to a number of conditions
set forth in the Plan, some of which may be waived by Eastern Europe Fund. In
addition, the Plan may be amended in any mutually agreeable manner, except that
no amendment may be made subsequent to the Meeting that would have a material
adverse effect on Eastern Europe Fund shareholders' interests.

POTENTIAL NET REDEMPTION

     If a large percentage of Eastern Europe Fund shareholders redeem their
shares after the Reorganization, significant costs may be imposed on Developing
Markets Fund. The proposed redemption fee is intended to offset such costs, but,
to the extent those costs exceed the fees charged, those costs would be borne by
Developing Markets Fund shareholders. To meet redemption requests, Developing
Markets Fund may be required either to draw upon a line of credit, which would
impose some interest costs, or to sell portfolio securities, which would incur
brokerage costs and may result in capital gain or loss that would not otherwise
have been recognized. Any gain would, to the extent it is not otherwise offset
during the year, be distributed to shareholders. Recognition and distribution of
gain would have two negative consequences: first, non-redeeming shareholders
would be required to pay taxes on larger capital gain distributions than they
would

                                       17
<PAGE>   24

otherwise; and second, Developing Markets Fund may need to sell additional
portfolio securities to raise cash to make the distributions, potentially
resulting in recognition of additional capital gain.

ACCOUNTING TREATMENT

     The Reorganization will be accounted for on a tax-free combined basis.
Accordingly, the book cost basis to Developing Markets Fund of the Assets will
be the same as Eastern Europe Fund's book cost basis of the Assets.

FEDERAL INCOME TAX CONSIDERATIONS

     The exchange of all of Eastern Europe Fund's assets solely for Developing
Markets Fund Class A shares and Developing Markets Fund's assumption of all the
liabilities of Eastern Europe Fund is intended to qualify for federal income tax
purposes as a tax-free reorganization under section 368 of the Code. Eastern
Europe Fund and the Trust will receive an opinion of Kirkpatrick & Lockhart LLP,
their counsel, substantially to the effect that:

          (1) Developing Markets Fund's acquisition of the Assets in exchange
     solely for Developing Markets Fund Class A shares and Developing Markets
     Fund's assumption of the Liabilities, followed by Eastern Europe Fund's
     distribution of those shares pro rata to its shareholders constructively in
     exchange for their Eastern Europe Fund shares, will qualify as a
     reorganization within the meaning of section 368(a)(1)(C) of the Code, and
     each Fund will be "a party to a reorganization" within the meaning of
     section 368(b) of the Code;

          (2) Eastern Europe Fund will recognize no gain or loss on the transfer
     of the Assets to Developing Markets Fund in exchange solely for Developing
     Markets Fund Class A shares and Developing Markets Fund's assumption of the
     Liabilities or on the subsequent distribution of those shares to Eastern
     Europe Fund's shareholders in constructive exchange for their Eastern
     Europe Fund shares;

          (3) Developing Markets Fund will recognize no gain or loss on its
     receipt of the Assets in exchange solely for Developing Markets Fund Class
     A shares and its assumption of the Liabilities;

          (4) Developing Markets Fund's basis for the Assets will be the same as
     Eastern Europe Fund's basis therefor immediately before the Reorganization,
     and Developing Markets Fund's holding period for the Assets will include
     Eastern Europe Fund's holding period therefor;

          (5) An Eastern Europe Fund shareholder will recognize no gain or loss
     on the constructive exchange of all its Eastern Europe Fund shares solely
     for Developing Markets Fund Class A shares pursuant to the Reorganization;
     and

          (6) An Eastern Europe Fund shareholder's aggregate basis for the
     Developing Markets Fund Class A shares to be received by it in the
     Reorganization will be the same as the aggregate basis for its Eastern
     Europe Fund shares to be constructively surrendered in exchange for those
     Developing Market Fund shares, and its holding period for those Developing
     Market Fund Class A shares will include its holding period for those
     Eastern Europe Fund shares, provided they are held as capital assets by the
     shareholder on the Closing Date.

     Notwithstanding the foregoing, however, the opinion will not express any
conclusion about the tax consequences of the Reorganization regarding the
treatment of unrealized gain or loss on Assets (such as certain futures and
foreign currency contracts) that is required to be recognized for federal income
tax purposes under a market-to-market system of accounting. The Funds do not
expect that the amount of such gain will be significant.

     Utilization by Developing Markets Fund after the Reorganization of any
pre-Reorganization capital losses realized by Eastern Europe Fund would be
subject to limitation in future years under the Code.

     Shareholders of Eastern Europe Fund should consult their tax advisers
regarding the effect, if any, of the Reorganization in light of their individual
circumstances. Because the foregoing discussion only relates to the

                                       18

federal income tax consequences of the Reorganization, those shareholders also
should consult their tax advisers as to state and local tax consequences, if
any, of the Reorganization.

                           ORGANIZATION OF THE FUNDS

     Developing Markets Fund is a non-diversified series of the Trust, an
open-end management investment company. Developing Markets Fund commenced
operations, as a series of AIM Investment Funds, Inc. ("Investment Funds,
Inc."), an open-end management investment company on November 1, 1997, as the
successor (in a reorganization) to G.T. Global Developing Markets Fund, Inc., a
closed-end investment company that had commenced operations on January 11, 1994.
The Trust was organized as a Delaware business trust on May 7, 1998, and on
September 8, 1998, it acquired the assets and assumed the liabilities of
Investment Funds, Inc. As a result of this acquisition, Developing Markets Fund
became a series of the Trust. The operations of the Trust, as a Delaware
business trust, are governed by its Agreement and Declaration of Trust, as
amended, and Delaware law. The overall direction and supervision of Developing
Markets Fund is the responsibility of the Trust's Board, which has the primary
duty of ensuring that the Fund's general investment policies and programs are
adhered to and the Fund is properly administered.

     Eastern Europe Fund is a non-diversified closed-end management investment
company that was organized as a Massachusetts business trust under the name
"G.T. Greater Europe Fund" on December 6, 1989. On May 31, 1996, the Fund's
investment focus was narrowed and its name changed to "G.T. Global Eastern
Europe Fund." Concurrent with the name change, the Fund was converted to
"interval fund" status pursuant to Rule 23c-3 under the 1940 Act and has since
conducted annual repurchase offers for its shares. On May 29, 1998, the Fund was
renamed "AIM Eastern Europe Fund." Eastern Europe Fund shares have been listed
and publicly traded on the NYSE under the symbol "GTF" since March 29, 1990. The
operations of Eastern Europe Fund, as a Massachusetts business trust, are
governed by its Agreement and Declaration of Trust, as amended, and
Massachusetts law. The overall direction and supervision of Eastern Europe Fund
is the responsibility of its Board, which has the primary duty of ensuring that
the Fund's general investment policies and programs are adhered to and the Fund
is properly administered.

     To the knowledge of Eastern Europe Fund's management, as of the Record
Date, the Trustees and Officers of Eastern Europe Fund owned, as a group, less
than 1% of the outstanding shares of Eastern Europe Fund.

     There were thirteen meetings of Eastern Europe Fund's Board held during the
Fund's fiscal year ended October 31, 1998. The Board has a Nominating and Audit
Committee composed of Miss Quigley (Chairman) and Messrs. Anderson, Bayley and
Patterson. The purpose of the Nominating and Audit Committee is to nominate
persons to serve as Trustees, review annual audits of Eastern Europe Fund, and
recommend firms to serve as independent auditors for Eastern Europe Fund. The
Nominating and Audit Committee does not normally consider nominees recommended
by security holders. During Eastern Europe Fund's last completed fiscal year,
the Nominating and Audit Committee met five times. During the fiscal year ended
October 31, 1998, each Trustee attended at least 75% of the total number of
meetings of the Board held during their tenure, and each member of the
Nominating and Audit Committee attended at least 75% of the meetings of that
committee.

     All of Eastern Europe Fund's Trustees also serve as directors or trustees
of some or all of the other investment companies managed, administered or
advised by AIM. Eastern Europe Fund pays each Trustee, who is not a director,
officer or employee of AIM or any affiliated company, an annual retainer
component, plus a per-meeting fee component for each Board or committee meeting
attended by such Trustee and reimburses travel and other out-of-pocket expenses
incurred in connection with attending such meetings. The table below summarizes
the compensation of Eastern Europe Fund's Trustees for the fiscal year ended
October 31, 1998 and provides the total compensation of the Board members by the
Fund Complex for the fiscal year ended October 31, 1998.

                                PROPOSAL NO. 3:
                        RATIFICATION OF THE SELECTION OF
                         INDEPENDENT PUBLIC ACCOUNTANTS

     At a meeting called for the purpose of such selection, the firm of
PricewaterhouseCoopers LLP was selected by Eastern Europe Fund's Board,
including its trustees who are not "interested persons" of Eastern Europe Fund,
Developing Markets Fund, AIM or IAML, as the independent public accountants to
audit the books and accounts of Eastern Europe Fund for the fiscal year ending
October 31, 1999 and to include its opinion in financial statements filed with
the SEC. The Board has directed the submission of this selection to the Eastern
Europe Fund shareholders for ratification. PricewaterhouseCoopers LLP has
advised the Board that it has no financial interest in Eastern Europe Fund. For
the fiscal year ended October 31, 1998, the professional services rendered by
PricewaterhouseCoopers LLP included the issuance of an opinion on the financial
statements of Eastern Europe Fund and an opinion on other reports of Eastern
Europe Fund filed with the SEC. Representatives of PricewaterhouseCoopers LLP
are not expected to be present at the Meeting, but have been given the
opportunity to make a statement if they so desire and will be available should
any matter arise requiring their presence.

     REQUIRED VOTE. Ratification of the selection of PricewaterhouseCoopers LLP

                                   APPENDIX A

              AGREEMENT AND PLAN OF REORGANIZATION AND TERMINATION

     THIS AGREEMENT AND PLAN OF REORGANIZATION AND TERMINATION ("Agreement") is
made as of May 13, 1999, between AIM Investment Funds, a Delaware business trust
("Trust"), on behalf of AIM Developing Markets Fund, a segregated portfolio of
assets ("series") thereof ("Acquiring Fund"), and AIM Eastern Europe Fund, a
Massachusetts business trust ("Target"). (Acquiring Fund and Target are
sometimes referred to herein individually as a "Fund" and collectively as the
"Funds," and Trust and Target are sometimes referred to herein individually as
an "Investment Company" and collectively as the "Investment Companies.") All
agreements, representations, actions, and obligations described herein made or
to be taken or undertaken by Acquiring Fund are made and shall be taken or
undertaken by Trust.

     The Investment Companies wish to effect a reorganization described in
section 368(a)(1)(C) of the Internal Revenue Code of 1986, as amended ("Code").
The reorganization will involve the transfer of Target's assets to Acquiring
Fund in exchange solely for voting shares of beneficial interest ("shares") in
Acquiring Fund and the assumption by Acquiring Fund of Target's liabilities,
followed by the constructive distribution of those shares pro rata to the
holders of shares in Target ("Target Shares") in exchange therefor, all on the
terms and conditions set forth in this Agreement (which is intended to be, and
is adopted as, a "plan of reorganization" within the meaning of the regulations
under the Code). The foregoing transactions are referred to herein collectively
as the "Reorganization."

     Acquiring Fund is an open-end management investment company. Its shares are
divided into four classes, designated Class A, Class B, Class C, and Advisor
Class shares; only Acquiring Fund's Class A shares ("Acquiring Fund Shares") are
involved in the Reorganization.

     Target is a closed-end management investment company that has only a single
class of shares. Target Shares can be purchased and sold only on the New York
Stock Exchange ("NYSE"), except for purchases by Target through periodic
repurchase offers pursuant to Rule 23c-3 under the Investment Company Act of
1940, as amended ("1940 Act").

     In consideration of the mutual promises contained herein, the parties agree
as follows:

1. PLAN OF REORGANIZATION AND TERMINATION

     1.1. Target agrees to assign, sell, convey, transfer, and deliver all of
its assets described in paragraph 1.2 ("Assets") to Acquiring Fund. Acquiring
Fund agrees in exchange therefor --

          (a) to issue and deliver to Target the number of full and fractional
     (rounded to the third decimal place) Acquiring Fund Shares, determined by
     dividing the net value of Target (computed as set forth in paragraph 2.1)
     by the net asset value ("NAV") of an Acquiring Fund Share (computed as set
     forth in paragraph 2.2), and

          (b) to assume all of Target's liabilities described in paragraph 1.3
     ("Liabilities").

     Such transactions shall take place at the Closing (as defined in paragraph
3.1).

     1.2. The Assets shall include, without limitation, all cash, cash
equivalents, securities, receivables (including interest and dividends
receivable), claims and rights of action, rights to register shares under
applicable securities laws, books and records, deferred and prepaid expenses
shown as assets on Target's books, and other property owned by Target at the
Effective Time (as defined in paragraph 3.1).

     1.3. The Liabilities shall include (except as otherwise provided herein)
all of Target's liabilities, debts, obligations, and duties of whatever kind or
nature, whether absolute, accrued, contingent, or otherwise, whether or not
arising in the ordinary course of business, whether or not determinable at the
Effective Time, and whether or not specifically referred to in this Agreement.
Notwithstanding the foregoing, Target agrees to use its best efforts to
discharge all its known Liabilities before the Effective Time.
<PAGE>   34

     1.4. At or immediately before the Effective Time, Target shall declare and
pay to its shareholders a dividend and/or other distribution in an amount large
enough so that it will have distributed substantially all (and in any event not
less than 90%) of its investment company taxable income (computed without regard
to any deduction for dividends paid) and substantially all of its realized net
capital gain, if any, for the current taxable year through the Effective Time.

     1.5. At the Effective Time (or as soon thereafter as is reasonably
practicable), Target shall distribute the Acquiring Fund Shares received by it
pursuant to paragraph 1.1 to Target's shareholders of record, determined as of
the Effective Time (each a "Shareholder" and collectively "Shareholders"), in
constructive exchange for their Target Shares. Such distribution shall be
accomplished by Trust's transfer agent's opening accounts on Acquiring Fund's
share transfer books in the Shareholders' names and transferring such Acquiring
Fund Shares thereto. Each Shareholder's account shall be credited with the
respective pro rata number of full and fractional (rounded to the third decimal
place) Acquiring Fund Shares due that Shareholder. All outstanding Target
Shares, including any represented by certificates, shall simultaneously be
canceled on Target's share transfer books. Acquiring Fund shall not issue
certificates representing the Acquiring Fund Shares issued in connection with
the Reorganization.

     1.6. As soon as reasonably practicable after distribution of the Acquiring
Fund Shares pursuant to paragraph 1.5, but in all events within six months after
the Effective Time, Target shall be terminated and any further actions shall be
taken in connection therewith as required by applicable law.

     1.7. Any reporting responsibility of Target to a public authority is and
shall remain its responsibility up to and including the date on which it is
terminated.

     1.8. Any transfer taxes payable upon issuance of Acquiring Fund Shares in a
name other than that of the registered holder on Target's books of the Target
Shares constructively exchanged therefor shall be paid by the person to whom
such Acquiring Fund Shares are to be issued, as a condition of such transfer.

2. VALUATION

     2.1. For purposes of paragraph 1.1(a), Target's net value shall be (a) the
value of the Assets computed as of the close of regular trading on the NYSE on
the date of the Closing ("Valuation Time"), using the valuation procedures set
forth in Target's most recent annual report to its shareholders, less (b) the
amount of the Liabilities as of the Valuation Time.

     2.2. For purposes of paragraph 1.1(a), the NAV of an Acquiring Fund Share
shall be computed as of the Valuation Time, using the valuation procedures set
forth in Acquiring Fund's then-current prospectus relating to Acquiring Fund
Shares ("Prospectus") and statement of additional information ("SAI").

     2.3. All computations pursuant to paragraphs 2.1 and 2.2 shall be made by
or under the direction of A I M Advisors, Inc.

3. CLOSING AND EFFECTIVE TIME

     3.1. The Reorganization, together with related acts necessary to consummate
the same ("Closing"), shall occur at the Funds' principal office on August 27,
1999, or at such other place and/or on such other date as to which the parties
may agree. All acts taking place at the Closing shall be deemed to take place
simultaneously as of the close of business on the date thereof or at such other
time as to which the parties may agree ("Effective Time"). If, immediately
before the Valuation Time, (a) the NYSE is closed to trading or trading thereon
is restricted or (b) trading or the reporting of trading on the NYSE or
elsewhere is disrupted, so that accurate appraisal of the net value of Target
and the NAV of an Acquiring Fund Share is impracticable, the Effective Time
shall be postponed until the first business day after the day when such trading
shall have been fully resumed and such reporting shall have been restored.

     3.2. Target's fund accounting and pricing agent shall deliver at the
Closing a certificate of an authorized officer verifying that the information
(including adjusted basis and holding period, by lot) concerning the Assets,
including all portfolio securities, transferred by Target to Acquiring Fund, as
reflected on Acquiring Fund's books immediately following the Closing, does or
will conform to such information on Target's books
                                       A-2
<PAGE>   35

immediately before the Closing. Target's custodian shall deliver at the Closing
a certificate of an authorized officer stating that (a) the Assets held by the
custodian will be transferred to Acquiring Fund at the Effective Time and (b)
all necessary taxes in conjunction with the delivery of the Assets, including
all applicable federal and state stock transfer stamps, if any, have been paid
or provision for payment has been made.

     3.3. Target shall deliver to Trust at the Closing a list of the names and
addresses of the Shareholders and the number of outstanding Target Shares owned
by each Shareholder, all as of the Effective Time, certified by Target's
Secretary or Assistant Secretary. Trust's transfer agent shall deliver at the
Closing a certificate as to the opening on Acquiring Fund's share transfer books
of accounts in the Shareholder's names. Trust shall issue and deliver a
confirmation to Target evidencing the Acquiring Fund Shares to be credited to
Target at the Effective Time or provide evidence satisfactory to Target that
such Acquiring Fund Shares have been credited to Target's account on Acquiring
Fund's books. At the Closing, each party shall deliver to the other such bills
of sale, checks, assignments, stock certificates, receipts, or other documents
as the other party or its counsel may reasonably request.

     3.4. Each Investment Company shall deliver to the other at the Closing a
certificate executed in its name by its President or a Vice President in form
and substance satisfactory to the recipient and dated the Effective Time, to the
effect that the representations and warranties it made in this Agreement are
true and correct at the Effective Time except as they may be affected by the
transactions contemplated by this Agreement.

<PAGE>   42

     terms, except as the same may be limited by bankruptcy, insolvency,

     6.6. Each Investment Company shall have received an opinion of Counsel,
addressed to and in form and substance satisfactory to it, as to the federal
income tax consequences mentioned below ("Tax Opinion"). In rendering the Tax
Opinion, Counsel may rely as to factual matters, exclusively and without
independent verification, on the representations made in this Agreement (or in
separate letters addressed to Counsel) and the certificates delivered pursuant
to paragraph 3.4. The Tax Opinion shall be substantially to the effect that,
based on the facts and assumptions stated therein and conditioned on
consummation of the Reorganization in accordance with this Agreement, for
federal income tax purposes:

          6.6.1. Acquiring Fund's acquisition of the Assets in exchange solely
     for Acquiring Fund Shares and Acquiring Fund's assumption of the
     Liabilities, followed by Target's distribution of those shares pro rata to
     the Shareholders constructively in exchange for their Target Shares, will
     qualify as a reorganization within the meaning of section 368(a)(1)(C) of
     the Code, and each Fund will be "a party to a reorganization" within the
     meaning of section 368(b) of the Code;

          6.6.2. Target will recognize no gain or loss on the transfer of the
     Assets to Acquiring Fund in exchange solely for Acquiring Fund Shares and
     Acquiring Fund's assumption of the Liabilities or on the subsequent
     distribution of those shares to the Shareholders in constructive exchange
     for their Target Shares;

          6.6.3. Acquiring Fund will recognize no gain or loss on its receipt of
     the Assets in exchange solely for Acquiring Fund Shares and its assumption
     of the Liabilities;

                                      A-10
<PAGE>   43

          6.6.4. Acquiring Fund's basis for the Assets will be the same as
     Target's basis therefor immediately before the Reorganization, and
     Acquiring Fund's holding period for the Assets will include Target's
     holding period therefor;

          6.6.5. A Shareholder will recognize no gain or loss on the
     constructive exchange of all its Target Shares solely for Acquiring Fund
     Shares pursuant to the Reorganization; and

          6.6.6. A Shareholder's aggregate basis for the Acquiring Fund Shares
     to be received by it in the Reorganization will be the same as the
     aggregate basis for its Target Shares to be constructively surrendered in
     exchange for those Acquiring Fund Shares, and its holding period for those
     Acquiring Fund Shares will include its holding period for those Target
     Shares, provided they are held as capital assets by the Shareholder at the
     Effective Time.

Notwithstanding subparagraphs 6.6.2 and 6.6.4, the Tax Opinion may state that no
opinion is expressed as to the effect of the Reorganization on the Funds or any
Shareholder with respect to any asset as to which any unrealized gain or loss is
required to be recognized for federal income tax purposes at the end of a
taxable year (or on the termination or transfer thereof) under a mark-to-market
system of accounting.

     At any time before the Closing, either Investment Company may waive any of
the foregoing conditions (except that set forth in paragraph 6.1) if, in the
judgment of its Board, such waiver will not have a material adverse effect on
its Fund's shareholders' interests.

7. BROKERAGE FEES AND EXPENSES

     7.1. Each Investment Company represents and warrants to the other that
there are no brokers or finders entitled to receive any payments in connection
with the transactions provided for herein.

     7.2. Each Fund will bear its own Reorganization expenses.

8. ENTIRE AGREEMENT: NO SURVIVAL

     Neither party has made any representation, warranty, or covenant not set
forth herein, and this Agreement constitutes the entire agreement between the
parties. The representations, warranties, and covenants contained herein or in
any document delivered pursuant hereto or in connection herewith shall not
survive the Closing.

9. TERMINATION OF AGREEMENT

     This Agreement may be terminated at any time at or prior to the Effective
Time, whether before or after approval by Target's shareholders:

     9.1. By either Fund (a) in the event of the other Fund's material breach of
any representation, warranty, or covenant contained herein to be performed at or
prior to the Effective Time, (b) if a condition to its obligations has not been
met and it reasonably appears that such condition will not or cannot be met, or
(c) if the Closing has not occurred on or before December 31, 1999; or

     9.2. By the parties' mutual agreement.

In the event of termination under paragraphs 9.1(c) or 9.2, there shall be no
liability for damages on the part of either Fund, or the trustees or officers of
either Investment Company, to the other Fund.

10. AMENDMENT

     This Agreement may be amended, modified, or supplemented at any time,
notwithstanding approval thereof by Target's shareholders, in any manner
mutually agreed upon in writing by the parties; provided that following such
approval no such amendment shall have a material adverse effect on the
Shareholders' interests.

11. MISCELLANEOUS

     11.1. This Agreement shall be governed by and construed in accordance with

INVESTMENT OBJECTIVES AND STRATEGIES
- --------------------------------------------------------------------------------

The fund's primary investment objective is long-term growth of capital and its
secondary investment objective is income, to the extent consistent with seeking
growth of capital.

  The fund seeks to meet these objectives by investing substantially all of its
assets in issuers in developing countries, i.e., those that are in the initial
stages of their industrial cycles. The fund will invest a majority of its assets
in equity securities, and may also invest in debt securities, of developing
countries. The fund considers issuers in "developing countries" to be those (1)
organized under the laws of a developing country or have a principal office in a
developing country; (2) that derive 50% or more, alone or on a consolidated
basis, of their total revenues from business in developing countries; or (3)
whose securities are trading principally on a stock exchange, or in an over-the-
counter market, in a developing country. The fund will normally invest in
issuers in at least four countries, but it will invest no more than 25% of its
assets in issuers in any one country. The fund also may hold no more than 40% of
its assets in any one foreign currency and securities denominated in or indexed
to such currency. The fund may invest in debt securities when economic and other
factors appear to favor such investments. The fund may also invest up to 100% of
its assets in lower-quality debt securities, i.e., "junk bonds."

  The fund may invest up to 50% of its total assets in the following types of
developing market debt securities: (1) debt securities issued or guaranteed by
governments, their agencies, instrumentalities or political subdivisions, or by
government owned, controlled or sponsored entities, including central banks
(sovereign debt), and "Brady Bonds"; (2) interests in issuers organized and
operated for the purpose of restructuring the investment characteristics of
sovereign debt; (3) debt securities issued by banks and other business entities;
and (4) debt securities denominated in or indexed to the currencies of emerging
markets. Brady Bonds are debt restructurings that provide for the exchange of
cash and loans for newly issued bonds. There is no requirement with respect to
the maturity or duration of debt securities in which the fund may invest.

  The portfolio managers focus on companies that have experienced above-average,
long-term growth in earnings and have excellent prospects for future growth. In
selecting countries in which the fund will invest, the portfolio managers also
consider such factors as the prospect for relative economic growth among
countries or regions, economic or political conditions, currency exchange
fluctuations, tax considerations and the liquidity of a particular security. The
portfolio managers consider whether to sell a particular security when any of
those factors materially changes.

  The fund is non-diversified. 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.

  In anticipation of or in response to adverse market conditions or for cash
management purposes, the fund may hold all or a portion of its assets in cash
(U.S. dollars, foreign currencies or multinational currency units), money market
instruments or high-quality debt securities. As a result, the fund may not
achieve its investment objectives.

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

There is a risk that you could lose all or a portion of your investment in the
fund and that the income you may receive from your investment may vary. The
value of your investment in the fund will go up and down with the prices of the
securities in which the fund invests. The prices of equity securities change in
response to many factors including the historical and prospective earnings of
the issuer, the value of its assets, general economic conditions, interest
rates, investor perceptions, and market liquidity. Debt securities are
particularly vulnerable to credit risk and interest rate fluctuations. When
interest rates rise, bond prices fall; the longer a bond's duration, the more
sensitive it is to this risk.

  The prices of foreign securities may be further affected by other factors,
including:

- - Currency exchange rates--The dollar value of the fund's foreign investments
  will be affected by changes in the exchange rates between the dollar and the
  currencies in which those investments are traded.

- - Political and economic conditions--The value of the fund's foreign investments
  may be adversely affected by political and social instability in their home
  countries and by changes in economic or taxation policies in those countries.

- - Regulations--Foreign companies generally are subject to less stringent
  regulations, including financial and accounting controls, than are U.S.
  companies. As a result, there generally is less publicly available information
  about foreign companies than about U.S. companies.

- - Markets--The securities markets of other countries are smaller than U.S.
  securities markets. As a result, many foreign securities may be less liquid
  and more volatile than U.S. securities.

  These factors may affect the prices of securities issued by foreign companies
located in developing countries more than those in countries with mature
economies. For example, many developing countries have, in the past, experienced
high rates of inflation or sharply devalued their currencies against the U.S.
dollar, thereby causing the value of investments in companies located in those
countries to decline. Transaction costs are often higher in developing countries
and there may be delays in settlement procedures.

                          ---------------------------
                          AIM DEVELOPING MARKETS FUND
                          ---------------------------

  Sovereign debt securities of developing country governments are generally
lower-quality debt securities. Sovereign debt securities are subject to the
additional risk that, under some political, diplomatic, social or economic
circumstances, some developing countries that issue lower-quality debt
securities may be unable or unwilling to make principal or interest payments as
they come due.

  Compared to higher-quality debt securities, junk bonds involve greater risk of
default or price changes due to changes in the credit quality of the issuer
because they are generally unsecured and may be subordinated to other creditors'
claims. The value of junk bonds often fluctuates in response to company,
political or economic developments and can decline significantly over short
periods of time or during periods of general or regional economic difficulty.
During those times, the bonds could be difficult to value or to sell at a fair
price. Credit ratings on junk bonds do not necessarily reflect their actual
market risk.

  Because it is non-diversified, the fund may invest in fewer issuers than if it
were a diversified fund. The value of the fund's shares may vary more widely,
and the fund may be subject to greater investment and credit risk, than if the
fund invested more broadly.

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

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

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

(1) If you buy $1,000,000 or more of Class A shares and redeem these shares
    within 18 months from the date of purchase, you may pay a 1% contingent
    deferred sales charge (CDSC) at the time of redemption.
(2) The investment advisor has contractually agreed to limit net expenses for
    Class A, B and C shares of the fund to 2.00%, 2.50% and 2.50%, respectively,
    not including interest expenses.

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

EXPENSE EXAMPLE

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

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

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

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

CHOOSING A SHARE CLASS

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

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

                                       distributions(1)

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

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

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

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

DISTRIBUTION AND SERVICE (12b-1) FEES

Each AIM Fund (except AIM Tax-Free Intermediate Fund) has adopted 12b-1 plans
that allow the AIM Fund to pay distribution fees to A I M Distributors, Inc.
(the distributor) for the sale and distribution of its shares and fees for
services provided to shareholders, all or a substantial portion of which are
paid to the dealer of record. Because the AIM Fund pays these fees out of its
assets on an ongoing basis, over time these fees will increase the cost of your
investment and may cost you more than paying other types of sales charges.

                                     B-11                            MCF--03/99

SALES CHARGES

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

INITIAL SALES CHARGES

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

prior to 18 months after the date of purchase. The distributor may pay a dealer
concession and/or a service fee for purchases of $1,000,000 or more.

CONTINGENT DEFERRED SALES CHARGES FOR

CLASS B AND CLASS C SHARES

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

COMPUTING A CDSC

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

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

You may qualify for reduced sales charges or sales charge exceptions. To qualify
for these reductions or exceptions, you or your financial consultant must
provide sufficient information at the time of purchase to verify that your
purchase qualifies for such treatment.

REDUCED SALES CHARGES

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

Rights of Accumulation

You may combine your new purchases of Class A shares with Class A shares
currently owned for the purpose of qualifying for the lower initial sales charge
rates that apply to larger purchases. The applicable initial sales charge for
the new purchase is based on the total of your current purchase and the current
value of all Class A shares you own.

Letters of Intent

Under a Letter of Intent (LOI), you commit to purchase a specified dollar amount
of Class A shares of AIM Funds during a

13-month period. The amount you agree to purchase determines the initial sales
charge you pay. If the full face amount of the LOI is not invested by the end of
the 13-month period, your account will be adjusted to the higher initial sales
charge level for the amount actually invested.

INITIAL SALES CHARGE EXCEPTIONS

You will not pay initial sales charges

- - on shares purchased by reinvesting dividends and distributions;

- - when exchanging shares among certain AIM Funds;

- - when using the reinstatement privilege; and

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

CONTINGENT DEFERRED SALES CHARGE (CDSC) EXCEPTIONS

You will not pay a CDSC

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

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

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

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

There may be other situations when you may be able to purchase or redeem shares
at reduced or without sales charges. Consult the fund's Statement of Additional
Information for details.

SPECIAL PLANS

AUTOMATIC INVESTMENT PLAN

You can arrange for periodic investments in any of the AIM Funds by authorizing
the AIM Fund to withdraw the amount of your investment from your bank account on
a day or dates you specify and in an amount of at least $50. You may stop the
Automatic Investment Plan at any time by giving the transfer agent notice ten
days prior to your next scheduled withdrawal.

DOLLAR COST AVERAGING

Dollar Cost Averaging allows you to make automatic monthly or quarterly
exchanges, if permitted, from one AIM Fund account to one or more other AIM Fund
accounts with the identical registration. The account from which exchanges are
to be made must have a minimum balance of $5,000 before you can use this option.
Exchanges will occur on (or about) the 10th or 25th day of the month, whichever
you specify, in the amount you specify. The minimum amount you can exchange to
another AIM Fund is $50.

AUTOMATIC DIVIDEND INVESTMENT

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

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

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

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

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

PORTFOLIO REBALANCING PROGRAM

If you have at least $5,000 in your account, you may participate in the
Portfolio Rebalancing Program. Under this Program, you can designate how the
total value of your AIM Fund holdings should be rebalanced, on a percentage
basis, between two and ten of your AIM Funds on a quarterly, semiannual or
annual basis. Your portfolio will be rebalanced through the exchange of shares
in one or more of your AIM Funds for shares of the same class of one or more
other AIM Funds in your portfolio. If you wish to participate in the Program,
make changes or cancel the Program, the transfer agent must receive your request
to participate, changes or cancellation in good order at least five business
days prior to the next rebalancing date, which is normally the 28th day of the
last month of the period you choose. We may modify, suspend or terminate the
Program at any time on 60 days' prior written notice.

RETIREMENT PLANS

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

REDEEMING SHARES

REDEMPTION FEES

We will not charge you any fees to redeem your shares; however, your broker or
financial consultant may charge service fees for handling these transactions.
Your shares may be subject to a contingent deferred sales charge (CDSC).

REDEMPTION OF AIM CASH RESERVE SHARES OF

AIM MONEY MARKET FUND ACQUIRED BY EXCHANGE

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

REDEMPTION OF CLASS B SHARES ACQUIRED BY

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

                              include (1) original signatures of all registered owners;
                              (2) the name of the AIM Fund and your account number; (3) if

                              necessary (see below). The transfer agent may require that
                              you provide additional information, such as corporate
                              resolutions or powers of attorney, if applicable. If you are
                              redeeming from an IRA account, you must include a statement
                              of whether or not you are at least 59 1/2 years old and
                              whether you wish to have federal income tax withheld from
                              your proceeds. The transfer agent may require certain other
                              information before you can redeem from an employer-sponsored
                              retirement plan. Contact your employer for details.

By Telephone                  Call the transfer agent. You will be allowed to redeem by
                              telephone if (1) the proceeds are to be mailed to the
                              address on record with us or transferred electronically to a
                              pre-authorized checking account; (2) the address on record
                              with us has not been changed within the last 30 days; (3)
                              you do not hold physical share certificates; (4) you can
                              provide proper identification information; (5) the proceeds
                              of the redemption do not exceed $50,000; and (6) you have
                              not previously declined the telephone redemption privilege.
                              Certain accounts, including retirement accounts and 403(b)
                              plans, may not redeem by telephone. The transfer agent must
                              receive your call during the hours the NYSE is open for
                              business in order to effect the redemption at that day's
                              closing price.

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

TIMING AND METHOD OF PAYMENT

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

REDEMPTION BY MAIL

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

REDEMPTION BY TELEPHONE

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

PAYMENT FOR SYSTEMATIC WITHDRAWALS

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

EXPEDITED REDEMPTIONS

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

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

REDEMPTIONS BY CHECK

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

You may redeem shares of these AIM Funds by writing checks in amounts of $250 or
more if you have completed an authorization form. Redemption by check is not
available for retirement accounts.
SIGNATURE GUARANTEES

We require a signature guarantee when you redeem by mail and

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

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

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

(4) you request that payment be sent to a new address or an address that changed
    in the last 30 days.

The transfer agent will accept a guarantee of your signature by a number of
financial institutions. Call the transfer agent for additional information. Some
institutions have transaction amount maximums for these guarantees. Please check
with the guarantor institution.

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

REDEMPTIONS BY THE AIM FUNDS

If your account has been open at least one year, you have not made an additional
purchase in the account during the past six calendar months, and the value of
your account falls below $500 for three consecutive months due to redemptions or
exchanges (excluding retirement accounts), the AIM Funds have the right to
redeem the account after giving you 60 days' prior written notice. You may avoid
having your account redeemed during the notice period by bringing the account
value up to $500 or by utilizing the Automatic Investment Plan.
  If an AIM Fund determines that you have provided incorrect information in
opening an account or in the course of conducting subsequent transactions, the
AIM Fund may, at its discretion, redeem the account and distribute the proceeds
to you.

EXCHANGING SHARES

You may, under certain circumstances, exchange shares in one AIM Fund for those
of another AIM Fund. Before requesting an exchange, review the prospectus of the
AIM Fund you wish to acquire. Exchange privileges also apply to holders of the
Connecticut General Guaranteed Account, established for tax-qualified group
annuities, for contracts purchased on or before June 30, 1992.

PERMITTED EXCHANGES

Except as otherwise stated below, you may exchange your shares for shares of the
same class of another AIM Fund. You also may exchange AIM Cash Reserve Shares of
AIM Money Market Fund for Class A shares of another AIM Fund, or vice versa. You
may be required to pay an initial sales charge when exchanging from a Fund with
a lower initial sales charge than the one into which you are exchanging. If you
exchange from Class A shares not subject to a CDSC into Class A shares subject
to those charges, you will be charged a CDSC when you redeem the exchanged
shares. The CDSC charged on redemption of those shares will be calculated
starting on the date you acquired those shares through exchange.

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

YOU WILL NOT PAY A SALES CHARGE WHEN EXCHANGING:

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

(2) Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free
    Intermediate Fund for

    (a) one another;

    (b) AIM Cash Reserve Shares of AIM Money Market Fund or Class A shares of
        AIM Tax-Exempt Cash Fund; or

    (c) Class A shares of another AIM Fund, but only if
       (i)  you acquired the original shares before May 1, 1994; or

       (ii) you acquired the original shares on or after May 1, 1994 by way of
            an exchange from shares with higher sales charges;

(3) AIM Cash Reserve Shares of AIM Money Market Fund or Class A shares of AIM
    Tax-Exempt Cash Fund for

    (a) one another;

    (b) Class A shares of an AIM Fund subject to an initial sales charge (except
        for Class A shares of AIM Limited Maturity Treasury Fund and AIM
        Tax-Free Intermediate Fund), but only if you acquired the original
        shares

       (i)  prior to May 1, 1994 by exchange from Class A shares subject to an
            initial sales charge;
       (ii) on or after May 1, 1994 by exchange from Class A shares subject to
            an initial sales charge (except for Class A shares of AIM Limited
            Maturity Treasury Fund and AIM Tax-Free Intermediate Fund); or

    (c) Class A shares of AIM Limited Maturity Treasury Fund and AIM Tax-Free
        Intermediate Fund, but only if you acquired the original shares by
        exchange from Class A shares subject to an initial sales charge; or

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

EXCHANGES NOT PERMITTED

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

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

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

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

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

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

TERMS OF EXCHANGE

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

BY MAIL

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

BY TELEPHONE

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

EXCHANGING CLASS B AND CLASS C SHARES

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

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

PRICING OF SHARES

DETERMINATION OF NET ASSET VALUE
The price of each AIM Fund's shares is the fund's net asset value per share. The
AIM Funds value portfolio securities for which market quotations are readily
available at market value. The AIM Funds value short-term investments maturing
within 60 days at amortized cost, which approximates market value. AIM Money
Market Fund and AIM Tax-Exempt Cash Fund value all of their securities at
amortized cost. AIM High Income Municipal Fund, AIM Municipal Bond Fund, AIM
Tax-Exempt Bond Fund of Connecticut and AIM Tax-Free Intermediate Fund value
variable rate securities that have an unconditional demand or put feature
exercisable within seven days or less at par, which reflects the market value of
such securities.
  The AIM Funds value all other securities and assets at their fair value.
Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day. In addition, if,
between the time trading ends on a particular security and the close of the New
York Stock Exchange (NYSE), events occur that materially affect the value of the
security, the AIM Funds may value the security at its fair value as determined
in good faith by or under the supervision of the Board of Directors or Trustees
of the AIM Fund. The effect of using fair value pricing is that an AIM Fund's
net asset value will be subject to the judgment of the Board of Directors or
Trustees or its designee instead of being determined by the market. Because some
of the AIM Funds may invest in securities that are primarily listed on foreign
exchanges, the value of those funds' shares may change on days when you will not
be able to purchase or redeem shares.

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

TIMING OF ORDERS
You can purchase, exchange or redeem shares during the hours the NYSE is open
for business. The AIM Funds price purchase, exchange and redemption orders at
the net asset value calculated after the transfer agent receives an order in
good form. An AIM Fund may postpone the right of redemption only under unusual
circumstances, as allowed by the Securities and Exchange Commission, such as
when the NYSE restricts or suspends trading.

TAXES

In general, dividends and distributions you receive are taxable as ordinary
income or long-term capital gains for federal income tax purposes, whether you
reinvest them in additional shares or take them in cash. Distributions are
taxable to you at different rates depending on the length of time the fund holds
its assets. Different tax rates apply to ordinary income and long-term capital
gain distributions, regardless of how long you have held your shares. Every
year, you will be sent information showing the amount of dividends and
distributions you received from each AIM Fund during the prior year.

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

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

                       ANNUAL REPORT / MANAGERS' OVERVIEW

FUND ENDURES TUMULTUOUS YEAR IN EMERGING MARKETS

  Global market volatility dominated financial news in 1998. How did the Fund
  perform in this environment?

     We have been in a very challenging environment over the last year. The Fund
has suffered from the particular crises hitting individual countries, but it has
also been hurt by the increasingly negative perception of the riskiness of
emerging market investing.

     Results for the fiscal year ended October 31, 1998 were quite
disappointing. Total return was -37.09% for Class A shares. In comparison, the
MSCI Emerging Markets Free Index had a return of -30.98%.

     Since their inception on November 3, 1997, Class B shares had a cumulative
total return of -39.76%.

  Why was market turmoil so pervasive?

     The chain reaction started in Asia. Devalued currencies plus billions in
bad loans curtailed the region's ability to purchase goods and raw materials
from the world's sellers. When Asian companies flooded global commodities
markets with their inventories to produce desperately needed revenues, the
combination of oversupply and weakened demand caused prices to plummet,
contributing to worldwide deflation.

     Meanwhile, investors worried over news of Russia's overwhelming government
debt and the speculative borrowing practiced by its private banks. The situation
was especially troubling because it was set against a backdrop of weakening oil
and commodity prices. In August, Russia attempted to stabilize the banking
system by floating the ruble and suspending repayment of much of its foreign
debt. These events spurred a worldwide flight to quality, resulting in a
broad-based selloff. Even though Russia has a relatively small economy and
engages in just a tiny portion of world trade, many investors sustained millions
of dollars in losses from their exposure to both its debt and its equity
markets.

     In the wake of the Asian and Russian crises, investors began to reduce
their exposure to emerging markets. Latin America as well as the more open
markets in the Emerging EMEA (Europe, Middle East, and Africa) region suffered
both from investor flight and from the associated rising interest rates.

  What is your overall strategy in managing the Fund?

     First we determine the portfolio's target country allocations through a
top-down process that evaluates and scores countries based on their economic
growth, monetary cycle, government policy, and overall earnings growth. Our
stock research and selection process identifies stocks demonstrating growth, but
at a reasonable price. We then adjust our top-down allocation depending on the
availability of stocks suitable for investment in a particular country or
sector.

  What are the most significant changes you've made in the portfolio recently?

     The most important strategy we've taken in the last few months has been to
concentrate the portfolio in the markets and stocks where we are most confident
about the growth and valuation outlook. We've deliberately reduced the breadth
of holdings, and we've eliminated exposure to such highly unstable markets as
Pakistan, Sri Lanka, the Philippines, Thailand, and Malaysia. We've also
virtually eliminated the Fund's exposure to Russia. We don't expect to invest in
the Russian market until the political and economic environment has stabilized.

  Your largest country allocations are in latin america. Why did you favor this
  region?

     Despite recent market turbulence, we still believe in Latin America's
long-term potential. Relative to Asia, Latin America stands to perform much
better because of its more favorable trade ties to the United

                                       C-1
<PAGE>   65

States. The governments of the major economies in Latin America continue to
emphasize responsible fiscal and monetary policies. We feel that many are truly
committed to reform and deregulation. In fact, we've already witnessed important
restructuring efforts in the banking industries of several Latin American
countries and the first stages of fiscal reform in Brazil.

  Which stocks did you like?

     In Brazil, we own a number of privatization candidates. Many of the larger
utilities in Brazil appear undervalued given the strong medium-term growth
prospects for the economy. We emphasized oil and natural resource stocks because
they benefit from U.S. dollar revenues and from privatization efforts, which
should encourage greater operating efficiency. We also liked Brazil's utilities
such as Companhia Energetica de Minas Gerais (CEMIG), provider of electric power
to the Brazilian state of Minas Gerais. With political uncertainties now
reduced, such stocks have attracted investor interest once again.

     Our largest country allocation was in Mexico, which we believe will show
relatively stable economic growth into 1999. We've focused on blue chips as well
as stocks that stand to benefit from the large devaluation of the peso. Although
earnings will certainly be affected this year by the monetary correction, it
should help the competitive position of companies like Fomento Economico
Mexicano, S.A. de C.V., a soft-drink producer that exports to 63 countries
around the world.

  Where else did you find opportunities?

     One of the advantages of a global emerging markets portfolio is its
diversity. We have found a number of investments that were relatively sheltered
from global economic difficulties. For example, Hindustan Lever, one of the
largest low-end consumer good manufacturers in India, has announced
better-than-anticipated earnings expectations. The company makes soap,
toothpaste, and other personal care products.

     Global volatility has created good buying opportunities in such smaller
markets as Egypt and Morocco, which have demonstrated relatively strong growth,
falling interest rates, a decline in inflation, and attractive valuations.

     Similarly, problems in Russia have affected the prices of some of Eastern
Europe's more attractive stocks. For instance, Magyar Olaj-es Gazipari
(MOL) -- the gas distributor in Hungary, and KREDYT BANK of Poland are both
strong stocks that we believe are trading at a discount.

     We've raised our weighting in Greece, which is committed to joining
Europe's Economic and Monetary Union (EMU). In anticipation of that goal, the
country has made major strides in economic and fiscal reform. An example of a
Greek company we liked is Stet Hellas, a cellular company that has shown very
strong earnings growth in recent quarters.

  What about emerging-markets debt?

     Political and currency instabilities have kept us in a cautious mode with
this asset class. At the end of the reporting period, just over 11% of the
portfolio was in foreign government and government agency obligations. The
largest allocation went to Mexican government debt; the remainder was spread
across several Eastern European and Latin American countries. We have very
limited exposure to corporate bonds, with a scattering of holdings in Argentina,
Brazil, and a few other countries.

  What is your outlook for emerging markets and for the Fund?

     Although we expect growth to be disappointing over the next year, we
believe that emerging markets continue to offer a long-term investment option
for the most aggressive investors. The fundamentals driving growth in emerging
markets are still there: consumption, industrialization, a maturing financial
services industry, and continuing investment in infrastructure.

                                       C-2
<PAGE>   66

     Emerging markets potentially can offer earnings growth rates that exceed
those in developed countries; however, there are also many more risks associated
with this type of investment. We urge you to read your prospectus for more
information about the Fund's objectives, strategies, and risks.

Your Fund's total return includes sales charges, expenses, and management
fees. The performance of the Fund's Class B and Advisor Class shares will
differ from Class A shares due to differing fees and expenses. For Fund data
performance calculations and descriptions of indexes cited on this page,
please refer to the inside front cover.

On October 31, 1997, shareholders of record as of a certain date of GT Global
Developing Markets Fund, Inc., a closed-end fund, became Class A shareholders
of the Fund, an open-end fund. Performance of Class A shares prior to
November 1, 1997 reflects the different fees and expenses of the closed-end
fund.

MARKET VOLATILITY CAN SIGNIFICANTLY IMPACT SHORT-TERM PERFORMANCE. RESULTS OF
AN INVESTMENT MADE TODAY MAY DIFFER SUBSTANTIALLY FROM THE HISTORICAL
PERFORMANCE SHOWN.

ABOUT THIS CHART

The chart above compares your Fund's Class A shares to benchmark indexes. Use
of these indexes is intended to give you a general idea of your Fund's
comparative performance. It is important to understand the differences
between your Fund and these indexes. An index measures performance of a
hypothetical portfolio.

A market index such as the MSCI Emerging Markets Free Index is not managed
and incurs no sales charges, expenses, or fees. If you could buy all the
securities that make up a market index, you would incur expenses that would
affect your investment's return.

Since the last reporting period, AIM Developing Markets Fund has elected to
use the MSCI Emerging Markets Free Index as one of its benchmarks. This index
more closely reflects the performance of the securities in which the Fund
invests. The Fund will no longer be measured against the IFC Investable
Composite Index, the index published in previous reports to shareholders.

Because this is the first reporting period since we have adopted the new
index, SEC guidelines require that we compare the Fund's performance to both
the old and the new index.
