                        AIM ADVISOR LARGE CAP VALUE FUND
                     A PORTFOLIO OF AIM ADVISOR FUNDS, INC.
                          11 GREENWAY PLAZA, SUITE 100
                           HOUSTON, TEXAS 77046-1173

                                                                  April 25, 2000

Dear Shareholder:

     Enclosed is a combined proxy statement and prospectus seeking your approval
of a proposed combination of AIM Advisor Large Cap Value Fund ("Large Cap Value
Fund") with AIM Basic Value Fund ("Basic Value Fund") (each a "Fund"). Large Cap
Value Fund is a series of AIM Advisor Funds, Inc. (the "Company"), an open-end
management investment company organized as a Maryland corporation. Basic Value
Fund is a series of AIM Growth Series (the "Trust"), an open-end management
investment company organized as a Delaware business trust. If the proposal is
approved and implemented, each shareholder of Large Cap Value Fund automatically
would become a shareholder of Basic Value Fund.

     The Board of Directors of the Company believes that combining the two Funds
will benefit Large Cap Value Fund's shareholders by providing them with a
portfolio that has a broader investment mandate than Large Cap Value Fund. A I M
Advisors, Inc. ("AIM") serves as investment adviser to both Funds. INVESCO, Inc.
serves as sub-adviser to Large Cap Value Fund. The portfolio management team for
Basic Value Fund is experienced and has a performance record that is generally
superior to that of the portfolio management team for Large Cap Value Fund. To
achieve its investment objective of long-term growth of capital, Basic Value
Fund may invest in a wider variety of U.S. equity securities and foreign
securities. As a result, Basic Value Fund possesses greater flexibility than
Large Cap Value Fund to respond to opportunities in the marketplace. Basic Value
Fund's expenses are expected to decline following consummation of the proposed
combination, but are expected to be slightly higher than Large Cap Value Fund's
expenses. The accompanying document describes the proposed transaction and
compares the investment policies, operating expenses, and performance histories
of the Funds.

     Shareholders of Large Cap Value Fund are being asked to approve an
Agreement and Plan of Reorganization by and among the Company, the Trust, and
AIM that will govern the reorganization of Large Cap Value Fund into Basic Value
Fund. After careful consideration, the Board of Directors of the Company has
unanimously approved the proposal and recommends that you read the enclosed
materials carefully and then vote FOR the proposal.

     If you attend the meeting, you may vote your shares in person. If you
expect to attend the meeting in person, or have questions, please notify the
Company by calling 1-800-952-3502. If you do not expect to attend the meeting,
please fill in, date, sign and return the proxy card in the enclosed envelope
which requires no postage if mailed in the United States.

     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. You may also vote your shares on the Internet at the Fund's website
at http://www.aimfunds.com by following the instructions that appear on the
enclosed proxy insert.

     Thank you for your cooperation and continued support.

                                          Sincerely,

                                          /s/ CHARLES T. BAUER

                    COMBINED PROXY STATEMENT AND PROSPECTUS
                             DATED: APRIL 25, 2000

     This document is being furnished in connection with a special meeting of
shareholders of AIM Advisor Large Cap Value Fund ("Large Cap Value Fund"), an
investment portfolio of AIM Advisor Funds, Inc. (the "Company"), a Maryland
corporation, to be held at 11 Greenway Plaza, Suite 100, Houston, TX 77046 on
May 31, 2000, at 3:00 p.m., Central time (such meetings and any adjournments
thereof are referred to as the "Meeting"). At the Meeting, the shareholders of
Large Cap Value Fund are being asked to consider and approve an Agreement and
Plan of Reorganization (the "Agreement") by and among the Company, acting on
behalf of Large Cap Value Fund, AIM Growth Series (the "Trust"), a Delaware
business trust, acting on behalf of AIM Basic Value Fund ("Basic Value Fund"),
and A I M Advisors, Inc. ("AIM"). The Agreement provides for the combination of
Large Cap Value Fund with Basic Value Fund (each a "Fund") (the
"Reorganization"). The Agreement is attached as Appendix I to this Combined
Proxy Statement and Prospectus ("Proxy Statement/Prospectus"). THE BOARD OF
DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE AGREEMENT AS BEING IN THE
BEST INTEREST OF LARGE CAP VALUE FUND'S SHAREHOLDERS.

     Pursuant to the Agreement, all of the assets of Large Cap Value Fund will
be transferred to Basic Value Fund, Basic Value Fund will assume all of the
liabilities of Large Cap Value Fund, and the Trust will issue a number of full
and fractional shares of the applicable class of Basic Value Fund having an
aggregate value that, on the effective date of the Reorganization, is equal to
the aggregate net asset value of the shareholder's shares of common stock of the
corresponding class of Large Cap Value Fund. The value of each Large Cap Value
Fund shareholder's account with Basic Value Fund immediately after the
Reorganization will be the same as the value of such shareholder's account with
Large Cap Value Fund immediately prior to the Reorganization. The Reorganization
has been structured as a tax-free transaction. No initial sales charge will be
imposed in connection with the Reorganization.

     Basic Value Fund is a diversified series of the Trust, which is an open-end
management investment company. Basic Value Fund's investment objective is
long-term growth of capital. Basic Value Fund seeks to achieve its investment
objective by investing all of its investable assets in the Value Portfolio (the
"Portfolio") which, in turn, normally invests at least 65% of its total assets
in equity securities of U.S. issuers that have market capitalizations of greater
than $500 million and that the portfolio managers believe to be undervalued in
relation to long-term earning power or other factors.

     Prior to the closing date of the Reorganization, it is anticipated that the
master-feeder structure in which Basic Value Fund invests in the Portfolio will
be eliminated, and Basic Value Fund will invest directly in its portfolio
securities ("Restructuring"). Such Restructuring is conditioned on Basic Value
Fund's shareholders approving an investment advisory agreement with AIM. Unless
otherwise specified, the information in this Proxy Statement/Prospectus
regarding Basic Value Fund assumes that the Restructuring is consummated.

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

                                  INTRODUCTION

     This Proxy Statement/Prospectus is furnished in connection with the
solicitation of proxies by the Board of Directors of the Company from the
shareholders of Large Cap Value Fund 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 the
proposal to approve the Agreement and in accordance with management's
recommendation on other matters. The presence in person or by proxy of one-third
of the outstanding shares of common stock of Large Cap Value Fund at the Meeting
will constitute a quorum ("Quorum"). If a Quorum is not present at the Meeting
or a Quorum is present but sufficient votes to approve the proposal described
herein ("Proposal") 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 the
Proposal in favor of such an adjournment and will vote those proxies required to
be voted AGAINST the Proposal against such adjournment. In addition, if you
sign, date and return the proxy card, but give no voting instructions, the duly
appointed proxies may, in their discretion, vote upon such other matters as may
come before the Meeting.

     Approval of the Agreement requires the affirmative vote of a majority of
the shares cast by shareholders of Large Cap Value Fund 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. 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 the Company. To
be effective, such revocation must be received by the Secretary of the Company
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 April 3, 2000 (the
"Record Date"), are entitled to vote at the Meeting. On the Record Date, there
were 6,735,738.841 shares of Large Cap Value Fund outstanding. Each share is
entitled to one vote for each full share held, and a fractional vote for a
fractional share held. To the knowledge of the Trust's management, as of the
Record Date, there were no beneficial owners of 5% or more of the outstanding
shares of any class of Large Cap Value Fund, except as indicated below in
"Ownership of Large Cap Value Fund and Basic Value Fund Shares."

     The Company has engaged the services of Shareholder Communications
Corporation ("SCC") to assist it in the solicitation of proxies for the Meeting.
The Company expects to solicit proxies principally by mail, but the Company or
SCC may also solicit proxies by telephone, facsimile, telegraph, or personal
interview. The Company officers and employees of AIM who assist in proxy
solicitation will not receive any additional or special compensation for any
such efforts. The cost of shareholder solicitation incurred in connection with
the Reorganization is anticipated to be approximately $5,300 and will be borne
by Large Cap Value Fund and Basic Value Fund. The Company 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.
The Company may reimburse such brokers/dealer firms, custodians, nominees, and
fiduciaries for their reasonable expenses incurred in connection with such proxy
solicitation.

     The Company intends to mail this Proxy Statement/Prospectus and the
accompanying proxy on or about April 25, 2000.

                         REASONS FOR THE REORGANIZATION

BACKGROUND AND REASONS FOR THE REORGANIZATION

     The Company was organized in 1989 as a Maryland corporation, and is
registered with the SEC as an open-end, series, management investment company.
The Company was known as INVESCO Advisor Funds, Inc. prior to August 4, 1997,
and EBI Funds, Inc. prior to January 16, 1996. Large Cap Value Fund is a
diversified series of the Company. AIM became the investment adviser to each of
the Company's funds, including Large Cap Value Fund, on August 4, 1997. INVESCO,
Inc. ("INVESCO"), an affiliated company of AIM, currently serves as sub-adviser
to Large Cap Value Fund.

     The Trust was organized in 1985 as a Massachusetts business trust. The
Trust was reorganized on May 29, 1998, as a Delaware business trust, and is
registered with the SEC as an open-end, series, management investment company.
Prior to May 29, 1998, the Trust was known as G.T. Global Growth Series. Basic
Value Fund, formerly AIM America Value Fund and prior thereto, GT Global America
Value Fund, is a diversified series of the Trust. AIM became the investment
adviser to Basic Value Fund on September 8, 1998, after it acquired the parent
of the prior adviser, Chancellor LGT Asset Management, Inc.

     AIM proposes the Reorganization because Basic Value Fund has greater
investment flexibility and superior performance as compared to Large Cap Value
Fund. Basic Value Fund's expenses are currently higher than those of Large Cap
Value Fund. Basic Value Fund's expenses are expected to decline following
consummation of the proposed combination, but are expected to be slightly higher
than Large Cap Value Fund's expenses. AIM expects that the Reorganization would
provide benefits to both Large Cap Value Fund and Basic Value Fund by increasing
investment choices and possibly helping to achieve cost savings. As of February
16, 2000, Basic Value Fund had approximately $155.7 million in assets, and Large
Cap Value Fund had approximately $140.8 million.

BOARD CONSIDERATIONS

     AIM, the investment adviser to Basic Value Fund and Large Cap Value Fund
has proposed the Reorganization and recommended that the Board of Directors of
the Company approve the Reorganization. Based upon AIM's recommendation and
extensive inquiry into a number of factors with respect to the Reorganization,
the Board of Directors of the Company, including a majority of directors who are
not "interested persons" ("Independent Directors") 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 the shareholders of Large Cap Value
Fund, that the terms of the Reorganization are fair and reasonable, and that the
interests of Large Cap Value Fund's shareholders will not be diluted as a result
of the Reorganization.

     At a meeting of the Board of Directors held on March 8, 2000, AIM proposed
that the Board of Directors approve the Reorganization of Large Cap Value Fund
into Basic Value Fund. The Board received from AIM written materials that
described the structure and tax consequences of the Reorganization and contained
information concerning Large Cap Value Fund and Basic Value Fund, including
comparative total return and fee and expense information, a comparison of the
investment objectives and primary investment policies of Large Cap Value Fund
and Basic Value Fund, pro forma expense ratios, and biographical information on
the portfolio managers of the Portfolio.

     The Board made an 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 effect of the Reorganization on
the expense ratio of Basic Value Fund and that expense ratio relative to each
Fund's current expense ratio; (3) the capabilities, experience, and performance
of the portfolio management team for Basic Value Fund; (4) the Funds' respective
investment performances; (5) the relationship of risk versus return for the
Funds; (6) the net effect to the assets of Large Cap Value Fund of redemptions
exceeding new investments; (7) the costs to be incurred by each Fund as a result
of the Reorganization; (8) the tax consequences of the Reorganization; (9)
possible alternatives to the Reorganization, including continuing to operate
Large Cap Value Fund on a stand-alone basis or liquidating Large Cap Value Fund;
and (10) the potential benefits of the Reorganization to other persons,
especially AIM and its affiliates.

     In considering the Reorganization, the Board considered the fact that Basic
Value Fund has a broader investment mandate than Large Cap Value Fund and can
invest in a wider variety of U.S. equity and foreign securities than can Large
Cap Value Fund. AIM noted its belief that Basic Value Fund's ability to invest
more extensively in U.S. equity and foreign securities gives it greater
flexibility than Large Cap Value Fund to effectively respond to opportunities in
the markets. Such flexibility could, over the long term, benefit shareholders.
The Board noted that although investment in Basic Value Fund involves greater
risk than in investment in Large Cap Value Fund, Basic Value Fund has exhibited
superior performance than Large Cap Value Fund. The Board also noted that
redemptions from Large Cap Value Fund currently exceed new investments in the
Fund.

     The Board noted that although the expense ratios of Basic Value Fund are
higher than Large Cap Value Fund, and the pro forma expense ratio of the
combined Basic Value Fund is slightly higher than that of Large Cap Value Fund
for Class A, Class B and Class C shares, as shown below, AIM has contractually
agreed to waive fees and reimburse expenses to limit Basic Value Fund's total
annual operating expenses (excluding interest, taxes, dividend expense on short
sales and extraordinary items) of Class A, Class B and Class C to 1.32%, 1.97%
and 1.97%, (Large Cap Value Fund's current expense accrual rates) respectively,
until June 30, 2001. The Board was further advised that the expense ratio of
Basic Value Fund also could decrease if, as a result of the Reorganization, the
combined Fund experienced increased sales of its shares.

     The Board also considered the capabilities, experience, and performance of
the portfolio management team of Basic Value Fund and the performance of Large
Cap Value Fund in relation to the performance of Basic Value Fund. AIM advised
the Board that, while past performance is no guarantee of future results, the
portfolio management team of Basic Value Fund produced superior investment
performance than the portfolio management team of Large Cap Value Fund. As of
December 31, 1999, the Morningstar ratings and Lipper Inc. rankings for Large

     AIM also advised the Board that it expected to receive some immediate
benefits from the Reorganization. AIM expects to realize some administrative
benefit from the combination of Large Cap Value Fund and Basic Value Fund as a
result of economies of scale. In addition, AIM currently pays an affiliated
sub-adviser a portion of the advisory fees that it receives from Large Cap Value
Fund, and AIM Distributors,

                                        3
<PAGE>   11

an affiliate of AIM, voluntarily waives fees for Large Cap Value Fund. As a
result of the Reorganization, AIM (or an affiliate) would no longer waive any
portion of its fees, and AIM would retain its entire advisory fee. However, AIM
will receive a lower advisory and administration fee when the assets of Large
Cap Value Fund become assets of Basic Value Fund. The effective rate of current
advisory and administration fees for Basic Value Fund for the fiscal year ended
December 31, 1999, was 0.73%. The effective rate of current advisory and
administration fees for Large Cap Value Fund for the same period was 0.75%.
However, AIM noted that it could benefit in the future if the combined assets of
Basic Value Fund grow faster after the proposed Reorganization than the assets
of Large Cap Value Fund and Basic Value Fund separately would have grown in the
absence of the Reorganization.

     The Board noted that no initial sales or other charges would be imposed on
any Basic Value Fund shares issued to Large Cap Value Fund shareholders in
connection with the Reorganization. Finally, the Board reviewed the principal
terms of the Agreement. The Board also noted that Large Cap Value Fund would be
provided with an opinion of counsel that the Reorganization would be tax-free to
Large Cap Value Fund and its shareholders.

     On the basis of the information provided to the Board and on their
evaluation of the Reorganization, the Board determined that the proposed
Reorganization will not dilute the interests of shareholders of Large Cap Value
Fund or Basic Value Fund and is in the best interest of the shareholders of
Large Cap Value Fund in view of Basic Value Fund's broader investment mandate
and greater flexibility to invest. Therefore, the Board recommended the approval
of the Agreement by the shareholders of Large Cap Value Fund at a special
meeting.

                                    SYNOPSIS

THE REORGANIZATION

     The Reorganization will result in the combination of Large Cap Value Fund
with Basic Value Fund. Large Cap Value Fund is a portfolio of the Company, a
Maryland corporation. Basic Value Fund is a portfolio of the Trust, a Delaware
business trust.

     If shareholders of Large Cap Value Fund approve the Agreement and other
closing conditions are satisfied, all of the assets of Large Cap Value Fund will
be transferred to Basic Value Fund, Basic Value Fund will assume all of the
liabilities of Large Cap Value Fund, and the Trust will issue Class A shares of
Basic Value Fund to Large Cap Value Fund's Class A shareholders, Class B shares
of Basic Value Fund to Large Cap Value Fund's Class B shareholders, and Class C
shares of Basic Value Fund to Large Cap Value Fund's Class C shareholders. The
shares of Basic Value Fund issued in the Reorganization will have an aggregate
net asset value equal to the value of Large Cap Value Fund's net assets
transferred to Basic Value Fund. Shareholders will not pay any initial sales
charge for shares of Basic Value Fund received in connection with the
Reorganization. The value of each shareholder's account with Basic Value Fund
immediately after the Reorganization will be the same as the value of such
shareholder's account with Large Cap Value Fund immediately prior to the
Reorganization. A copy of the Agreement is attached as Appendix I to this Proxy
Statement/Prospectus. See "Additional Information About the Agreement" herein.

     The Company will receive an opinion of Kirkpatrick & Lockhart LLP, the
Trust's counsel, to the effect that the Reorganization will constitute a
tax-free reorganization within the meaning of section 368(a)(1) of the Internal
Revenue Code of 1986, as amended ("Code"). Accordingly, no gain or loss will be
recognized to either Fund or their shareholders as a result of the
Reorganization. See "Additional Information About the Agreement -- Federal Tax
Considerations" herein.

COMPARISON OF LARGE CAP VALUE FUND AND BASIC VALUE FUND

  INVESTMENT OBJECTIVES AND POLICIES

     The investment objective and policies of Large Cap Value Fund are similar
to the investment objective and policies of Basic Value Fund with which it will
combine.

                                        4
<PAGE>   12

     Basic Value Fund seeks to provide long-term growth of capital by investing
at least 65% of its total assets in equity securities of U.S. issuers that have
market capitalizations of greater than $500 million and that the portfolio
managers believe to be undervalued in relation to long-term earning power or
other factors. Large Cap Value Fund seeks to achieve a high total return on
investment through growth of capital and current income, without regard to
federal income tax considerations, by investing primarily in equity securities
of issuers with market capitalizations among the largest 800 publicly traded
U.S. corporations.

  INVESTMENT ADVISORY SERVICES

     AIM serves as investment adviser, and INVESCO serves as sub-adviser, to
Large Cap Value Fund. AIM also serves as investment adviser to the Portfolio,
and it is anticipated that AIM will serve as Basic Value Fund's investment
adviser. INVESCO does not act as sub-adviser for Basic Value Fund; the
Reorganization will end INVESCO's role in the management of Large Cap Value
Fund's assets.

  PERFORMANCE

     Set forth below are average annual total returns for the periods indicated
for Basic Value Fund and Large Cap Value Fund. The average annual total return
figures take into account sales charges applicable to purchases of Class A
shares or redemptions of Class B or Class C shares of the Funds. Past
performance cannot guarantee future results.

  HYPOTHETICAL EXAMPLE OF EFFECT OF EXPENSES

     An investor would have directly or indirectly paid the following expenses
on a $10,000 investment under the existing and estimated fees and expenses
stated above, assuming a 5% annual return. To the extent fees are waived, the
expenses will be lower.

(2) Assumes payment of the applicable CDSC.

(3) For Class B shares, this number reflects the conversion to Class A shares
    eight years following the end of the calendar month in which the purchase
    was made.

  SALES CHARGES

     No sales charges are applicable to shares of Basic Value Fund received in
connection with the Reorganization.

     The Class A shares of both Basic Value Fund and Large Cap Value Fund are
sold subject to a maximum initial sales charge of 5.50%. Class B shares of both
Funds are sold subject to a maximum contingent deferred sales charge ("CDSC") of
5.00% of the lesser of the net asset value ("NAV") at time of purchase or sale,
which declines to zero after six years. The Class C shares of both Funds are
sold without initial sales charges but are subject to a maximum CDSC of 1.00% of
the lesser of the NAV at time of purchase or sale, only during the first year.
For purposes of calculating the CDSC, the holding period for the Class B and
Class C shares distributed to Class B and Class C shareholders of Large Cap
Value Fund, respectively, will be treated as having the same period that the
shares of Large Cap Value Fund previously held. New purchases of Class A, Class
B, and Class C shares of Basic Value Fund by any shareholders will be subject to
their terms, including, for example, for Class A shares, the 5.50% initial sales
charge. As is currently the case for both Funds, no CDSC will be applied to
redemptions of Class B shares that represent reinvested dividends or other
distributions, nor will Class A shares so acquired be subject to any initial
sales charge.

  DISTRIBUTION; PURCHASE, EXCHANGE AND REDEMPTION

     Shares of Basic Value Fund and Large Cap Value Fund are distributed by
A I M Distributors, Inc. ("AIM Distributors"). The Class A shares of Basic Value
Fund and Large Cap Value Fund pay a fee in the amount of 0.35% of average daily
net assets to AIM Distributors for distribution services. AIM Distributors has
contractually agreed to waive 0.10% of the fee relating to Class A shares of
Large Cap Value Fund. The Class B and Class C shares of Basic Value Fund and
Large Cap Value Fund pay AIM Distributors fees at an annual rate of 1.00% of the
average daily net assets attributable to the Class B and Class C shares,
respectively, for distribution services. For more information, see the
discussion under the heading "Shareholder Information -- Distribution and
Service (12b-1) Fees" in the Basic Value Fund Prospectus attached as Appendix II
to this Proxy Statement/Prospectus.

     Purchase and redemption procedures are the same for Basic Value Fund and
Large Cap Value Fund. Shares of Basic Value Fund and Large Cap Value Fund may be
exchanged for shares of other funds within The AIM Family of Funds--Registered
Trademark-- of the same class, as provided in each Fund's prospectus. No initial
sales charge will be imposed on the shares being acquired, and no CDSC will be
imposed on the shares being disposed of, through an exchange. However, a CDSC
may apply to redemptions of an AIM Fund's Class B or Class C shares acquired
through an exchange. Exchanges will be subject to minimum investment and other
requirements of the Fund into which exchanges are made.

                                  RISK FACTORS

     Basic Value Fund and Large Cap Value Fund are subject to substantially
similar investment risks as a result of their investment in equity securities of
U.S. issuers and foreign securities. Basic Value Fund is subject to additional
risk as a result of its investment in a greater percentage of equity securities
of small- and mid-cap U.S. issuers. The principal risks to Basic Value Fund from
investing in equity securities, foreign securities, and small- and mid-cap
companies are discussed herein.

EQUITY SECURITIES RISK

     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.

     Equity securities, particularly common stock, generally represent the most
junior position in an issuer's capital structure and entitle holders to an
interest in the assets of an issuer, if any, remaining after all more senior
claims have been satisfied.

FOREIGN SECURITIES RISK

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

SMALL-AND MID-CAP COMPANIES RISK

     Small-cap companies and, to a lesser degree, mid-cap companies may be more
vulnerable than larger companies to adverse business, economic, or market
developments. Smaller companies may have more limited product lines, markets, or
financial resources than companies with larger capitalizations, and may be more
dependent on a relatively small management group. In addition, smaller companies
may not be well known to the investing public, may not have institutional
ownership, and may have only cyclical, static, or moderate growth prospects.

     Most small-cap company stocks pay low or no dividends. Securities of
small-cap companies are generally less liquid and their prices more volatile
than those of securities of larger companies. The securities of some small-cap
companies may not be widely traded, and Basic Value Fund's position in
securities of such companies may be substantial in relation to the market for
such securities. Accordingly, it may be difficult for Basic Value Fund to
dispose of securities of these small-cap companies at prevailing market prices
in order to meet redemptions.

                COMPARISON OF INVESTMENT OBJECTIVES AND POLICIES

INVESTMENT OBJECTIVES OF BASIC VALUE FUND AND LARGE CAP VALUE FUND

     Basic Value Fund seeks long-term growth of capital.

     Large Cap Value Fund seeks high total return on investment through growth
of capital and current income, without regard to federal income tax
considerations.

<PAGE>   16

INVESTMENT POLICIES OF BASIC VALUE FUND AND LARGE CAP VALUE FUND

     Under normal market conditions, Basic Value Fund invests at least 65% of
its total assets in equity securities, including common stocks, preferred
stocks, convertible debt securities, and warrants to acquire such securities, of
U.S. issuers that have market capitalizations of greater than $500 million and
that the portfolio managers believe to be undervalued in relation to long-term
earning power or other factors. Basic Value Fund may also invest up to 35% of
its total assets in equity securities of U.S. issuers that have market
capitalizations of less than $500 million and in investment-grade
non-convertible debt securities, U.S. government securities, and high-quality
money market instruments, all of which are issued by U.S. issuers. It may also
invest up to 25% of its total assets in foreign securities.

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

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

     Under normal market conditions, Large Cap Value Fund invests at least 65%
of its investments in equity securities including common stocks and, to a lesser
extent, convertible securities, of selected companies with market
capitalizations among the largest 800 publicly traded U.S. corporations. The
portfolio managers may also invest up to 10% of its total assets in non-Canadian
foreign securities and unsponsored American Depositary Receipts (ADRs). The
portfolio managers may also invest up to 25% of Large Cap Value Fund's total
assets in Canadian securities and sponsored ADRs.

     In order to identify the securities having the best relative values, the
portfolio managers start with a list of securities of the 800 largest publicly
traded U.S. corporations, which they reduce to a proprietary database system and
fundamental analysis. The portfolio managers consider whether to sell a
particular security when it no longer qualifies for the list of eligible
securities.

     In anticipation of or in response to adverse market conditions, for cash
management purposes, or for defensive purposes, Large Cap Value Fund may
temporarily hold all or a portion of its assets in cash, money market
instruments, shares of affiliated money market funds, bonds, or other debt
securities. As a result, Large Cap Value Fund may not achieve its investment
objective.

MANAGEMENT DISCUSSION AND ANALYSIS OF PERFORMANCE

     A discussion of the performance of Basic Value Fund for the twelve month
period ended December 31, 1999, is set forth in Appendix III to this Proxy
Statement/Prospectus.

                              FINANCIAL HIGHLIGHTS

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

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

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

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

                   ADDITIONAL INFORMATION ABOUT THE AGREEMENT

TERMS OF THE REORGANIZATION

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

THE REORGANIZATION

     Basic Value Fund will acquire all of the assets of Large Cap Value Fund in
exchange for shares of Basic Value Fund and the assumption by Basic Value Fund
of the liabilities of Large Cap Value Fund. Consummation of the Reorganization
(the "Closing") is expected to occur on June 19, 2000, at 8:00 a.m. Eastern Time
(the "Effective Time") on the basis of values calculated as of the close of the
customary trading session of the NYSE on June 16, 2000.

     At the Effective Time, all of the assets of Large Cap Value Fund shall be
delivered to the Custodian for the account of Basic Value Fund in exchange for
the assumption by Basic Value Fund of all of the liabilities of any kind of
Large Cap Value Fund and delivery by AIM Growth Series directly to (i) the Large
Cap Value Fund Class A shareholders of a number of Basic Value Fund Class A
shares (including, if applicable, fractional shares rounded to the nearest
thousandth) and to (ii) the Large Cap Value Fund Class B shareholders of a
number of Basic Value Fund Class B shares (including, if applicable, fractional
shares rounded to the nearest thousandth) and to (iii) the Large Cap Value Fund
Class C shareholders of a number of Basic Value Fund Class C shares (including,
if applicable, fractional shares rounded to the nearest thousandth), having an
aggregate net asset value equal to the net value of the assets of Large Cap
Value Fund so transferred, assigned, and delivered.

OTHER TERMS

     The Agreement may be amended by mutual agreement of the Company and the
Trust notwithstanding shareholder approval thereof by Large Cap Value Fund's
shareholders, provided that following such approval no amendment shall be made
that has a material adverse effect on the interests of Large Cap Value Fund's
shareholders.

     Both the Company and the Trust have made representations and warranties in
the Agreement that are customary in matters such as the Reorganization. The
obligations of the Company and the Trust pursuant to the Agreement with respect
to Large Cap Value Fund or Basic Value Fund are subject to various conditions,
including the following: (a) the assets of Large Cap Value Fund to be acquired
by Basic Value Fund with which it will be combined shall constitute at least 90%
of the fair market value of the net assets and at least 70% of the fair market
value of the gross assets held by Large Cap Value Fund immediately prior to the
Reorganization; (b) the Trust's Registration Statement on Form N-14 under the
Securities Act of 1933 (the "1933 Act") shall have been filed with the SEC and
such Registration Statement shall have become effective, and no stop-order
suspending the effectiveness of the Registration Statement shall have been
issued, and no proceeding for that purpose shall have been initiated or
threatened by the SEC (and not withdrawn or terminated); (c) the shareholders of
Large Cap Value Fund shall have approved the Agreement; and (d) the Company and
the Trust shall have received an opinion from Kirkpatrick & Lockhart LLP that
the Reorganization will not result in the recognition of gain or loss for
Federal income tax purposes for Large Cap Value Fund, Basic Value Fund, or their
shareholders.

     Large Cap Value Fund and Basic Value Fund have each agreed to bear their
own expenses in connection with the Reorganization.

     The Board of Directors of the Company may waive without shareholder
approval any default by the Trust or any failure by the Trust to satisfy any of
the conditions to the Company's obligations as long as such a waiver will not
have a material adverse effect on the benefits intended under the Agreement for
the shareholders of Large Cap Value Fund. The Agreement may be terminated and
the Reorganization may be abandoned by either the Company or the Trust at any
time by mutual agreement of the Company and the Trust, or by either party in the
event that Large Cap Value Fund shareholders do not approve the Agreement or if
the Closing does not occur on or before December 31, 2000.

FEDERAL TAX CONSIDERATIONS

     The exchange of Large Cap Value Fund's Assets for Basic Value Fund shares
and Basic Value Fund's assumption of the liabilities of Large Cap Value Fund is
intended to qualify for federal income tax purposes as a tax-free reorganization
under section 368 of the Internal Revenue Code of 1986, as amended ("Code"). The
Trust will receive an opinion of Kirkpatrick & Lockhart LLP, its counsel,
substantially to the effect that:

     (i)   The acquisition of the assets of the Large Cap Value Fund by the
           Basic Value Fund in exchange solely for the Basic Value Fund Shares
           and the Basic Value Fund's assumption of the Large Cap Value Fund's
           liabilities, followed by the distribution of those Shares pro rata to
           the Large Cap Value Fund Shareholders constructively in exchange for
           their Large Cap Value Fund Shares, as provided in the Agreement, will
           qualify as a "reorganization" within the meaning of section 368(a) of
           the Code, and each of the Large Cap Value Fund and the Basic Value
           Fund will be a "party to a reorganization" within the meaning of
           368(b) of the Code.

     (ii)  The Large Cap Value Fund will recognize no gain or loss on the
           transfer of its assets to the Basic Value Fund in exchange solely for
           Basic Value Fund Shares and the Basic Value Fund's assumption of the
           Large Cap Value Fund's liabilities or on the distribution of those
           Shares to the Large Cap Value Fund Shareholders.

     (iii) The Basic Value Fund will recognize no gain or loss on its receipt of
           the assets of the Large Cap Value Fund in exchange solely for Basic
           Value Fund Shares and its assumption of the Large Cap Value Fund's
           liabilities.

                                       13
<PAGE>   21

     (iv)  The Basic Value Fund's basis for the assets of the Large Cap Value
           Fund transferred to it will be the same as the Large Cap Value Fund's
           basis therefor immediately before the Reorganization, and the Basic
           Value Fund's holding period for those assets will include the Large
           Cap Value Fund's holding period therefor.

     (v)   A Large Cap Value Fund Shareholder will recognize no gain or loss on
           the receipt of Basic Value Fund Shares in constructive exchange for
           all its Large Cap Value Fund Shares pursuant to the Reorganization.

     (vi)  A Large Cap Value Fund Shareholder's aggregate basis for the Basic
           Value Fund Shares received thereby in the Reorganization will be the
           same as the aggregate basis for its Large Cap Value Fund Shares to be
           constructively surrendered in exchange therefor, and its holding
           period for those Basic Value Fund Shares will include its holding
           period for those Large Cap Value Fund Shares, provided the Large Cap
           Value Fund Shareholder held the Large Cap Value Fund Shares as
           capital assets at the Effective Time.

     The 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.

     Utilization by Basic Value Fund after the Reorganization of
pre-Reorganization capital losses realized by Large Cap Value Fund could be
subject to limitation in future years under the Code.

     Shareholders of Large Cap Value 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 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.

ACCOUNTING TREATMENT

     The Reorganization will be accounted for on a tax-free combined basis.
Accordingly, the book cost basis to Basic Value Fund of the assets of Large Cap
Value Fund will be the same as the book cost basis of such assets to Large Cap
Value Fund.

                             RIGHTS OF SHAREHOLDERS

     The Trust is a Delaware business trust and the Company is a Maryland
corporation. There are many similarities between the two forms of organization.
For example, the responsibilities, powers, and fiduciary duties of the directors
of the Company are substantially the same as those of the trustees of the Trust.

     There are, however, certain differences between the two forms of
organization. The operations of the Trust, as a Delaware business trust, are
governed by its Agreement and Declaration of Trust, as amended (the "Declaration
of Trust") and Delaware law. The operations of the Company, a Maryland
corporation, are governed by its Articles of Incorporation, and amendments and
supplements thereto, and applicable Maryland law.

LIABILITY OF SHAREHOLDERS

     Shareholders of a Maryland corporation generally do not have personal
liability for the corporation's obligations, except that a shareholder may be
liable to the extent that he receives any distributions which exceeds the amount
which he could properly receive under Maryland law or where such liability is
necessary to prevent fraud.

     The Delaware Business Trust Act provides that shareholders of a Delaware
business trust shall be entitled to the same limitations of liability extended
to shareholders of private for-profit corporations. There is, however, a remote
possibility that, under certain circumstances, shareholders of a Delaware
business trust
                                       14
<PAGE>   22

might be held personally liable for the trust's obligations to the extent the
courts of another state that does not recognize such limited liability were to
apply the laws of such state to a controversy involving such obligations. The
Trust's Declaration of Trust provides that shareholders of Basic Value Fund
shall not be subject to any personal liability for acts or obligations of Basic
Value Fund and that every written agreement, obligation, or other undertaking
made or issued by Basic Value Fund shall contain a provision to the effect that
shareholders are not personally liable thereunder. In addition, the Declaration
of Trust provides for indemnification out of Basic Value Fund's property for any
shareholder held personally liable solely by reason of his or her being or
having been a shareholder. Therefore, the risk of any shareholder incurring
financial loss beyond his investment due to shareholder liability is limited to
circumstances in which Basic Value Fund itself is unable to meet its obligations
and the express disclaimer of shareholder liabilities is determined not to be
effective. Given the nature of the assets and operations of Basic Value Fund,
the possibility of Basic Value Fund being unable to meet its obligations is
considered remote, and even if a claim were brought against Basic Value Fund and
a court determined that shareholders were personally liable, it would likely not
impose a material obligation on a shareholder.

ELECTION OF TRUSTEES/DIRECTORS; TERMS

     The shareholders of the Company have elected the directors of the Company.
Each director serves until a successor is elected, subject to earlier death,
incapacitation, resignation, retirement or removal (see below). Shareholders may
elect successors to such directors only at annual or special meetings of
shareholders.

     The shareholders of the Trust have elected the trustees of the Trust. Such
trustees serve for the life of AIM Growth Series, subject to the earlier death,
incapacitation, resignation, retirement or removal (see below). Shareholders may
elect successors to such trustees only at annual or special meetings of
shareholders.

REMOVAL OF TRUSTEES/DIRECTORS

     A director of the Company may be removed by the affirmative vote of the
holders of a majority of the outstanding shares of the Company.

     A trustee of the Trust may be removed at any time by vote of at least
two-thirds of the trustees or by vote of two-thirds of the outstanding shares of
the Trust. The Declaration of Trust provides that vacancies may be filled by
appointment by the remaining trustees.

MEETING OF SHAREHOLDERS

     The Company is not required to hold annual meetings of shareholders and
does not intend to do so unless required by the 1940 Act. The Company's Bylaws
provide that a special meeting of shareholders may be called by the Chairman of
the Board of Directors, the President, a majority of the Board of Directors. In
addition, the Company's Bylaws provide that a special meeting of shareholders
may be called by the Secretary upon receipt of a request in writing, signed by
holders of shares entitled to cast at least 10% of the votes entitled to be cast
at the special meeting. Requests for special meetings must, among other things,
state the purpose of such meeting and the matters to be voted upon. No special
meeting need be called to consider any matter previously voted upon at a special
meeting called by the shareholders during the preceding twelve months, unless
requested by a majority of all shares entitled to vote at such meeting.

     The Trust is not required to hold annual meetings of shareholders unless
required by the 1940 Act and does not intend to do so. The Bylaws of the Trust
provide that a majority of the trustees may call special meetings of
shareholders and the trustees shall call a special meeting of the shareholders
upon written request of the holders of not less than 10% of Basic Value Fund's
shares. Special meetings may be called for the purpose of electing trustees or
for any other action requiring shareholder approval, or for any matter deemed by
the trustees to be necessary or desirable.

                                       15

LIABILITY OF TRUSTEES/DIRECTORS AND OFFICERS; INDEMNIFICATION

     Maryland law requires indemnification of a corporation's directors and
officers if a director or officer has been successful on the merits or otherwise
in the defense of certain proceedings unless limited by its charter. Maryland
law also permits indemnification for other matters unless it is established that
the act or omission giving rise to the proceeding was committed in bad faith, a
result of active and deliberate dishonesty, or one in which a director or
officer actually received an improper benefit. The Company's Articles of
Incorporation provides that the Company shall indemnify and advance expenses to
its currently acting and its former directors to the fullest extent that
indemnification of directors is permitted by Maryland law.

     Delaware law provides that trustees of a business trust shall not be liable
to the business trust or its shareholders for acting in good faith reliance on
the provisions of its governing instrument and that the trustees' liabilities
may be expanded or restricted by such instrument. Under the Trust's Declaration
of Trust, the trustees and officers of the Trust are not liable for any act or
omission or any conduct whatsoever in their capacity as trustees, except for
liability to the trust or shareholders due to willful misfeasance, bad faith,
gross negligence or reckless disregard of the duties involved in the conduct of
the office of trustee. Delaware law allows a business trust to indemnify and
hold harmless any trustee or other person against any and all claims and
demands. The Trust's Declaration of Trust provides for the indemnification of
its trustees and officers to the fullest extent permitted by Delaware law or
other applicable law.

TERMINATION

     Maryland law provides that the Company may be dissolved by the vote of a
majority of the Board of Directors and two-thirds of the shares entitled to vote
on the dissolution.

     The Trust or any series or class of shares of beneficial interest in the
Trust may be terminated by a majority shareholder vote of the Trust or the
affected series or class, respectively, or if there are fewer than 100
shareholders of record of the Trust or of such terminating series or class, the
trustees pursuant to written notice to the shares of the Trust or the affected
series or class.

VOTING RIGHTS OF SHAREHOLDERS

     Shareholders of a Maryland corporation such as the Company are entitled to
vote on, among other things, those matters which effect fundamental changes in
the corporate structure (such as a merger, consolidation or sale of
substantially all of the assets of the corporation) as provided by Maryland
corporation law.

     The Trust's Declaration of Trust grants shareholders power to vote only
with respect to the following: (i) election of trustees; (ii) removal of
trustees; (iii) approval of investment advisory contracts, as required by the
1940 Act; (iv) termination of the Trust or a series of class of its shares of
beneficial interest; (v) amendment of the Declaration of Trust; (vi) sale of all
or substantially all of the assets of the Trust or one of its investment
portfolios; (vii) merger or consolidation of the Trust or any of its investment
portfolios, with certain exceptions; and (viii) approval of such additional
matters as may be required by law or as the trustees, in their sole discretion,
shall determine.

DISSENTERS' RIGHTS

     Under Maryland law, the Company shareholders may not demand the fair value
of their shares from the successor company in a transaction involving the
transfer of Large Cap Value Fund's assets, and are bound by the terms of the
transaction.

     Neither Delaware law nor the Declaration of Trust confers upon the Trust's
shareholders appraisal or dissenters' rights.

                                       16
<PAGE>   24

AMENDMENTS TO ORGANIZATION DOCUMENTS

     Consistent with Maryland law, the Company reserves the right to amend,
alter, change, or repeal any provision contained in their Articles of
Incorporation in the manner now or hereafter prescribed by statute, including
any amendment that alters the contract rights, as expressly set forth in the
Articles of Incorporation, of any outstanding stock, and all rights conferred on
shareholders are granted subject to this reservation. The Board of Directors of
the Company may approve amendments to the Articles of Incorporation to classify
or reclassify unissued shares of a class of stock without shareholder approval.
Other amendments to the Company's Articles of Incorporation may be adopted if
approved by a vote of a majority of the shares at any meeting at which a quorum
is present. The Company's Bylaws provide that the Bylaws may be amended at any
regular meeting or special meeting of the stockholders provided that notice of
such amendment is contained in the notice of the special meeting. Except as to
any particular Bylaw which is specified as not subject to amendment by the Board
of Directors, the Bylaws may be also amended by the affirmative vote of a
majority of the Board of Directors at any regular or special meetings of the
Board.

     Consistent with Delaware law, the Board of Trustees of the Trust may,
without shareholder approval, amend the Declaration of Trust at any time, except
that no amendment may be made which reduces the indemnification provided to
shareholders or former shareholders or which change the preferences, voting
powers, rights, and privileges of outstanding shares in a manner materially
adverse to the shareholders of such shares, without approval of the affected
shareholders. The trustees shall have the power to alter, amend, or repeal the
Bylaws of the Trust or adopt new Bylaws at any time.

be delivered to the Custodian for the account of the Acquiring Fund in exchange
for the assumption by the Acquiring Fund of all of the Liabilities and delivery
by AGS directly to (a) the Acquired Fund Class A Shareholders of a number of the

Value attributable to the Acquired Fund Class A Shares by the net asset value of
an Acquiring Fund Class A Share as of the Valuation Time, (b) the Acquired Fund
Class B Shareholders of a number of the Acquiring Fund Class B Shares
(including, if applicable, fractional shares rounded to the nearest thousandth)
determined by dividing the Acquired Fund Net Value attributable to the Acquired

     (e) If, immediately before the Valuation Time, (i) the NYSE is closed to
trading or trading thereon is restricted or (ii) trading or the reporting of
trading on the NYSE or elsewhere is disrupted, so that accurate appraisal of the

Fund's Shares 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.

transfer books of the Acquired Fund will be permanently closed as of the
Valuation Time, and only requests for the redemption of Acquired Fund Shares
received in proper form prior to the Valuation Time shall be accepted by the

<PAGE>   35

requests for Acquiring Fund Shares to be distributed to the Acquired Fund
Shareholders under this Agreement (assuming that the transactions contemplated

Custodian on the Closing Date. No later than three (3) business days preceding
the Closing Date, AAF shall instruct the Custodian to transfer the Assets to the
account of the Acquiring Fund at the Effective Time. The Assets so delivered
shall be duly endorsed in proper form for transfer in such condition as to
constitute a good delivery thereof, in accordance with the custom of brokers,
and shall be accompanied by all necessary state stock transfer stamps, if any,
or a check for the appropriate purchase price thereof. Cash held by the Acquired
Fund shall be delivered at the Effective Time and shall be in the form of
currency or wire transfer in Federal funds, payable to the order of the account
of the Acquiring Fund at the Custodian.

     (b) If, on the Closing Date, the Acquired Fund is unable to make delivery
in the manner contemplated by Section 2.4(a) of securities purchased by it prior
to the Closing Date that have not yet been delivered to the Acquired Fund or its
broker, then AGS shall waive the delivery requirements of Section 2.4(a) with
respect to such undelivered securities if the Acquired Fund has delivered to the
Custodian by or on the Closing Date, and with respect to such undelivered
securities, executed copies of an agreement of assignment and escrow agreement
and due bills executed on behalf of said broker or brokers, together with such
other documents as may be required by AGS or the Custodian, including brokers'
confirmation slips.

     SECTION 2.5  Termination of Series. As soon as reasonably practicable, but
in all events within six months, after the Closing Date, the status of the
Acquired Fund as a designated series of shares of AAF shall be terminated;
provided, however, that such termination shall not be required if the
Reorganization is not consummated.

     SECTION 2.6  Issuance of Acquiring Fund Shares. At the Effective Time, (a)

held by such Acquired Fund Shareholder; (b) each Acquired Fund Class B
Shareholder shall be issued that number of full and fractional Acquiring Fund
Class B Shares having a net asset value equal to the Acquired Fund Net Value
attributable to the Acquired Fund Class B Shares then held by such Acquired Fund
Shareholder; and (c) each Acquired Fund Class C Shareholder shall be issued that
number of full and fractional Acquiring Fund Class C Shares having a net asset
value equal to the Acquired Fund Net Value attributable to the Acquired Fund
Class C Shares then held by such Acquired Fund Shareholder. All issued and
outstanding capital stock of the Acquired Fund shall thereupon be canceled on
the books of AAF. AAF shall provide instructions to the transfer agent of AGS
with respect to the Acquiring Fund Shares to be issued to each Acquired Fund
Shareholder. AGS shall have no obligation to inquire as to the validity,
propriety or correctness of any such instruction, but shall, in each case,
assume that such instruction is valid, proper and correct. AGS shall record on
its books the ownership of each class of Acquiring Fund Shares by Acquired Fund
Shareholders and shall forward a confirmation of such ownership to each of them.
No redemption or repurchase of such Acquiring Fund Shares credited to former
Acquired Fund Shareholders in respect of Acquired Fund shares represented by
unsurrendered shares certificates shall be permitted until such certificates
have been surrendered to AGS for cancellation, or if such certificates are lost
or misplaced, until lost certificate affidavits have been executed and delivered
to AGS.

     SECTION 2.7  Investment Securities. AIF's fund accounting and pricing agent
shall deliver at the Closing a certificate of an authorized officer thereof
verifying that the information (including adjusted basis and holding period, by
lot) concerning the Assets, including all portfolio securities, as reflected on
the Acquiring Fund's books immediately following the Closing does or will
conform to such information on the Acquired Fund's books immediately before the
Closing.

     SECTION 2.8  Liabilities. The Acquired Fund shall use reasonable best
efforts to discharge all of its known Liabilities, so far as may be possible,
prior to the Closing Date.

                                   ARTICLE 3

                     REPRESENTATIONS AND WARRANTIES OF AAF

     AAF, on behalf of the Acquired Fund, represents and warrants to AGS that:

     SECTION 3.1  Organization; Authority. AAF is duly organized, validly
existing and in good standing under the Maryland General Corporation Law, with
all requisite corporate power and authority to enter into this Agreement and
perform its obligations hereunder.

     SECTION 3.2  Registration and Regulation of AAF. AAF is duly registered
with the SEC as an investment company under the Investment Company Act, the
Acquired Fund is a duly established and designated series thereof, and all
Acquired Fund Shares that have been or are being offered for sale have been duly
registered under the Securities Act and have been duly registered, qualified or
are exempt from registration or qualification under the securities laws of each
state or other jurisdiction in which such shares have been or are being offered
for sale, and no action has been taken by AAF to revoke or rescind any such
registration or qualification. The Acquired Fund is in compliance in all
material respects with all applicable laws, rules and regulations, including,
without limitation, the Investment Company Act, the Securities Act, the Exchange
Act and all applicable state securities laws. The Acquired Fund is in compliance
in all material respects with the investment policies and restrictions
applicable to it set forth in the AAF Registration Statement currently in
effect. The value of the net Assets is determined using portfolio valuation
methods that comply in all material respects with the requirements of the
Investment Company Act and the policies of the Acquired Fund, and all purchases
and redemptions of Acquired Fund Shares have been effected at the net asset
value per share calculated in such manner.

     SECTION 3.3  Financial Statements. The books of account and related records
of the Acquired Fund fairly reflect in reasonable detail its assets, liabilities
and transactions in accordance with generally accepted accounting principles
applied on a consistent basis. The audited financial statements for the fiscal
year ended December 31, 1999, of the Acquired Fund previously delivered to AGS
(the "Acquired Fund Financial Statements") present fairly in all material
respects the financial position of the Acquired Fund as at the dates indicated
and the results of operations and changes in net assets for the periods then
ended in accordance with generally accepted accounting principles applied on a
consistent basis for the periods then ended.

     SECTION 3.4  No Material Adverse Changes; Contingent Liabilities. Since
December 31, 1999, no material adverse change has occurred in the financial
condition, results of operations, business, assets or liabilities, other than
changes resulting from any change in general conditions in the financial or
securities markets or the performance of any investments made by the Acquired
Fund or occurring in the ordinary course of business, of the Acquired Fund or
the status of the Acquired Fund as a regulated investment company under the
Code. There are no contingent Liabilities not disclosed in the Acquired Fund
Financial Statements that are required to be disclosed in accordance with
generally accepted accounting principles.

     SECTION 3.5  Acquired Fund Shares; Liabilities; Business
Operations. (a) The Acquired Fund Shares have been duly authorized and validly
issued and are fully paid and non-assessable.

     (b) AAF's management is unaware of any plan or intention of Acquired Fund
Shareholders to redeem, sell, or otherwise dispose of (i) any portion of their
Acquired Fund Shares before the Reorganization to any person "related" (within
the meaning of Section 1.368-1(e)(3) of the Income Tax Regulations under the
Code) to either Fund or (b) any portion of the Acquiring Fund Shares to be
received by them in the Reorganization to any person related (within such
meaning) to Acquiring Fund.

     (c) At the time of its Reorganization, the Acquired Fund shall not have
outstanding any warrants, options, convertible securities or any other type of
right pursuant to which any Person could acquire Acquired Fund Shares, except
for the right of investors to acquire Acquired Fund Shares at net asset value in
the normal course of its business as a series of an open-end management
investment company operating under the Investment Company Act.

     (d) From the date it commenced operations and ending on the Closing Date,
the Acquired Fund will have conducted its "historic business" (within the
meaning of Section 1.368-1(d)(2) of the Income Tax
                                       I-6
<PAGE>   37

Regulations under the Code) in a substantially unchanged manner. In anticipation
of the Reorganization, the Acquired Fund will not dispose of assets that, in the
aggregate, will result in less than 50% of its "historic business assets"
(within the meaning of Section 1.368-1(d)(3) of those regulations) being
transferred to the Acquiring Fund.

     (e) AAF does not have, and has not had during the six months prior to the
date of this Agreement, any employees, and shall not hire any employees from and
after the date of this Agreement through the Closing Date.

     SECTION 3.6  Accountants. KPMG LLP, which has reported upon the Acquired
Fund Financial Statements for the fiscal year ended December 31, 1999, are
independent public accountants as required by the Securities Act and the
Exchange Act.

     SECTION 3.7  Binding Obligation. This Agreement has been duly authorized,
executed and delivered by AAF on behalf of the Acquired Fund and, when this
Agreement has been duly authorized, executed and delivered by AGS on behalf of
the Acquiring Fund and approved by the Acquired Fund's shareholders, will
constitute the legal, valid and binding obligation of AAF enforceable against
AAF in accordance with its terms from and with respect to the revenues of the
Acquired Fund and the Assets, except as the enforceability hereof may be limited
by bankruptcy, insolvency, reorganization or similar laws relating to or
affecting creditors' rights generally, or by general equity principles (whether
applied in a court of law or a court of equity and including limitations on the
availability of specific performance or other equitable remedies).

     SECTION 3.8  No Breaches or Defaults. The execution and delivery of this
Agreement by AAF on behalf of the Acquired Fund and the performance by AAF of
its obligations hereunder have been duly authorized by all necessary corporate
action on the part of AAF, other than the Acquired Fund's shareholders'
approval, and do not, and on the Closing Date will not, (i) result in any
violation of the Articles of Incorporation or by-laws of AAF and (ii) result in
a breach of any of the terms or provisions of, or constitute (with or without
the giving of notice or the lapse of time or both) a default under, or give rise
to a right of termination, cancellation or acceleration of any obligation or to
the loss of a material benefit under, or result in the creation or imposition of
any Lien upon any property of the Acquired Fund or the Assets (except for such
breaches or defaults or Liens that would not reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect) under (A)
any indenture, mortgage or loan agreement or any other material agreement or
instrument to which AAF is a party or by which it may be bound and which relates
to the Assets or to which any property of the Acquired Fund may be subject; (B)
any Permit; or (C) any existing applicable law, rule, regulation, judgment,
order or decree of any Governmental Authority having jurisdiction over AAF or
any property of the Acquired Fund. The Acquired Fund is not under the
jurisdiction of a court in a proceeding under Title 11 of the United States Code
or similar case within the meaning of Section 368(a)(3)(A) of the Code.

     SECTION 3.9  Authorizations or Consents. Other than those that shall have
been obtained or made on or prior to the Closing Date and those that must be
made after the Closing Date to comply with Section 2.5 of this Agreement, no
authorization or approval or other action by, and no notice to or filing with,
any Governmental Authority will be required to be obtained or made by AAF in
connection with its due execution and delivery of this Agreement and its
consummation of the transactions contemplated hereby.

     SECTION 3.10  Permits. AAF has in full force and effect all approvals,
consents, authorizations, certificates, filings, franchises, licenses, notices,
permits and rights of Governmental Authorities (collectively, "Permits")
necessary for it to conduct its business as presently conducted as it relates to
the Acquired Fund, and there has occurred no default under any Permit, except
for the absence of Permits and for defaults under Permits the absence or default
of which would not reasonably be expected to have, individually or in the
aggregate, a Material Adverse Effect. To the knowledge of AAF there are no
proceedings relating to the suspension, revocation or modification of any
Permit, except for such that would not reasonably be expected, individually or
in the aggregate, to have a Material Adverse Effect.

     SECTION 3.11  No Actions, Suits or Proceedings. (a) There is no pending
action, litigation or proceeding, nor, to the knowledge of AAF, has any
litigation been overtly threatened in writing or, if

                                       I-7
<PAGE>   38

probable of assertion, orally, against AAF before any Governmental Authority
that questions the validity or legality of this Agreement or of the actions
contemplated hereby or that seeks to prevent the consummation of the
transactions contemplated hereby, including the Reorganization.

     (b) There are no judicial, administrative or arbitration actions, suits, or
proceedings instituted or pending or, to the knowledge of AAF, threatened in
writing or, if probable of assertion, orally, against AAF affecting any
property, asset, interest or right of the Acquired Fund, that could reasonably
be expected to have, individually or in the aggregate, a Material Adverse Effect
with respect to the Acquired Fund. There are not in existence on the date hereof
any plea agreements, judgments, injunctions, consents, decrees, exceptions or
orders that were entered by, filed with or issued by Governmental Authority
relating to AAF's conduct of the business of the Acquired Fund affecting in any
significant respect the conduct of such business. AAF is not, and has not been
to its knowledge, the target of any investigation by the SEC or any state
securities administrator with respect to its conduct of the business of the
Acquired Fund.

     SECTION 3.12  Contracts. AAF is not in default under any contract,
agreement, commitment, arrangement, lease, insurance policy or other instrument
to which it is a party and that involves or affects the Assets, by which the
assets, business, or operations of the Acquired Fund may be bound or affected,
or under which it or the assets, business or operations of the Acquired Fund
receives benefits, and which default could reasonably be expected, individually
or in the aggregate, to have a Material Adverse Effect, and, to the knowledge of
AAF there has not occurred any event that, with the lapse of time or the giving
of notice or both, would constitute such a default.

     SECTION 3.13  Properties and Assets. AAF, on behalf of the Acquired Fund,
has good and marketable title to all properties and assets reflected in the
Acquired Fund Financial Statements as owned by it, free and clear of all Liens,
except as described in the Acquired Fund Financial Statements.

     SECTION 3.14  Taxes. (a) The Acquired Fund is a "fund" as defined in
Section 851(g)(2) of the Code and has elected to be a regulated investment
company under Subchapter M of the Code. The Acquired Fund has qualified for
treatment as such for each taxable year since inception that has ended prior to
the Closing Date and will continue to satisfy the requirements of Subchapter M
of the Code to maintain such qualification for the period beginning on the first
day of its current taxable year and ending on the Closing Date. The Acquired
Fund has no earnings and profits accumulated in any taxable year in which the
provisions of Subchapter M of the Code did not apply to it. In order to (i)
insure continued qualification of the Acquired Fund for treatment as a regulated
investment company for tax purposes and (ii) eliminate any tax liability of the
Acquired Fund arising by reason of undistributed investment company taxable
income or net capital gain, AAF will declare on or prior to the Closing Date to
the shareholders of the Acquired Fund a dividend or dividends that, together
with all previous dividends, shall have the effect of distributing (A) all of
the Acquired Fund's investment company taxable income (determined without regard
to any deductions for dividends paid) for the taxable year ended December 31,
1999, and for the short taxable year beginning on January 1, 2000, and ending on
the Closing Date and (B) all of the Acquired Fund's net capital gain recognized
in its taxable year ended December 31, 1999, and in such short taxable year
(after reduction for any capital loss carryover).

     (b) The Acquired Fund has timely filed all Returns required to be filed by
it, and all Taxes with respect thereto have been paid, except where the failure
so to file or so to pay would not reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect. Adequate provision has been made
in the Acquired Fund Financial Statements for all Taxes in respect of all
periods ended on or before the date of such financial statements, except where
the failure to make such provisions would not reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect. No
deficiency for any Taxes has been proposed, assessed or asserted in writing by
any taxing authority against the Acquired Fund, where such deficiency would
reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect. No waivers of the time to assess any such Taxes are outstanding
nor are any written requests for such waivers pending, and no Returns of the
Acquired Fund are currently being or have been audited with respect to income
taxes or other Taxes by any Federal, state, local or foreign Tax authority.

                                       I-8

     (c) To the best knowledge of AAF, the fiscal year of the Acquired Fund has
not been changed for tax purposes since the date on which it commenced
operations.

     SECTION 3.15  Benefit and Employment Obligations. On or prior to the
Closing Date, the Acquired Fund will have no obligation to provide any
post-retirement or post-employment benefit to any Person, including under any
Benefit Plan, and will have no obligation to provide unfunded deferred
compensation or other unfunded or self-funded benefits to any Person.

     SECTION 3.16  Brokers. No broker, finder or similar intermediary has acted
for or on behalf of AAF in connection with this Agreement or the transactions
contemplated hereby, and no broker, finder, agent or similar intermediary is
entitled to any broker's, finder's or similar fee or other commission in
connection therewith based on any agreement, arrangement or understanding with
AAF or any action taken by it.

     SECTION 3.17  Voting Requirements. The vote of a majority of the
outstanding Acquired Fund Shares entitled to vote cast at a meeting at which a
quorum is present (the "Required Shareholder Vote") is the only vote of Acquired
Fund Shareholders necessary to approve this Agreement and the Reorganization
contemplated by this Agreement.

     SECTION 3.18  State Takeover Statutes. No state takeover statute or similar
statute or regulation applies to the Reorganization, this Agreement or any of
the transactions contemplated by this Agreement.

     SECTION 3.19  Books and Records. The books and records of AAF relating to
the Acquired Fund, reflecting, among other things, the purchase and sale of
Acquired Fund Shares, the number of issued and outstanding shares owned by the
Acquired Fund's shareholders and the states or other jurisdictions in which such

                     REPRESENTATIONS AND WARRANTIES OF AGS

     AGS, on behalf of the Acquiring Fund, represents and warrants to AAF as
follows:

     SECTION 4.1  Organization; Authority. AGS is duly organized, validly
existing and in good standing under the Delaware Business Trust Act, with all
requisite trust power and authority to enter into this Agreement and perform its
obligations hereunder.

     SECTION 4.2  Registration and Regulation of AGS. AGS is duly registered
with the SEC as an investment company under the Investment Company Act, and the
Acquiring Fund is a duly established and designated series thereof. The
Acquiring Fund is in compliance in all material respects with all applicable
laws, rules and regulations, including, without limitation, the Investment
Company Act, the Securities Act, the Exchange Act and all applicable state
securities laws. The Acquiring Fund is in compliance in all material respects
with the applicable investment policies and restrictions set forth in the AGS
Registration Statement. The value of the net assets of the Acquiring Fund is
determined using portfolio valuation methods that comply in all material
respects with the requirements of the Investment Company Act and the policies of
the Acquired Fund and all purchases and redemptions of Acquired Fund Shares have
been effected at the net asset value per share calculated in such manner.

     SECTION 4.3  Financial Statements. The books of account and related records
of the Acquiring Fund fairly reflect in reasonable detail its assets,
liabilities and transactions in accordance with generally accepted accounting
principles applied on a consistent basis. The audited financial statements for
the fiscal year ended December 31, 1999, of the Acquiring Fund previously
delivered to AAF (the "Acquiring Fund Financial Statements") present fairly in
all material respects the financial position of the Acquiring Fund as at the
dates indicated and the results of operations and changes in net assets for the
periods then ended in accordance with generally accepted accounting principles
applied on a consistent basis for the periods then ended.

     SECTION 4.4  No Material Adverse Changes; Contingent Liabilities. Since
December 31, 1999, no material adverse change has occurred in the financial
condition, results of operations, business, assets or liabilities of the
Acquiring Fund or the status of the Acquiring Fund as a regulated investment
company under the Code, other than changes resulting from any change in general
conditions in the financial or securities markets or the performance of any
investments made by the Acquiring Fund or occurring in the ordinary course of
business of the Acquiring Fund or AGS. There are no contingent liabilities of an
Acquiring Fund not disclosed in the Acquiring Fund Financial Statements which
are required to be disclosed in accordance with generally accepted accounting
principles.

     SECTION 4.5  Registration of Acquiring Fund Shares. (a) The shares of
beneficial interest in AGS are divided into six portfolios, including the
Acquiring Fund. The Acquiring Fund currently has three classes of shares, Class
A shares, Class B shares and Class C shares. Under its Agreement and Declaration
of Trust, AGS is authorized to issue an unlimited number of shares of the
Acquiring Fund.

     (b) The Acquiring Fund Shares to be issued pursuant to Section 2.6 shall on
the Closing Date be duly registered under the Securities Act by a Registration
Statement on Form N-14 of AGS then in effect.

     (c) The Acquiring Fund Shares to be issued pursuant to Section 2.6 are duly
authorized and on the Closing Date will be validly issued and fully paid and
non-assessable and will conform to the description thereof contained in the
Registration Statement on Form N-14 then in effect. At the time of its
Reorganization, the Acquiring Fund shall not have outstanding any warrants,
options, convertible securities or any other type of right pursuant to which any
Person could acquire Acquiring Fund Class A Shares, Acquiring Fund Class B
Shares, or Acquiring Fund Class C Shares, except for the right of investors to
acquire Acquiring Fund Class A Shares, Acquiring Fund Class B Shares, or
Acquiring Fund Class C Shares at net asset value in the normal course of its
business as a series of an open-end management investment company operating
under the Investment Company Act.

     (d) The combined proxy statement/prospectus (the "Combined Proxy
Statement/Prospectus") which forms a part of AGS's Registration Statement on
Form N-14 shall be furnished to AAF and the Acquired
                                      I-10

Fund Shareholders entitled to vote at the Acquired Fund Shareholders Meeting.
The Combined Proxy Statement/Prospectus and related Statement of Additional
Information of the Acquiring Fund, when they become effective, shall conform to
the applicable requirements of the Securities Act and the Investment Company Act
and shall not include any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not materially misleading, provided, however, that no representation or warranty
is made with respect to written information provided by AAF for inclusion in the
Combined Proxy Statement/ Prospectus.

     (e) The shares of the Acquiring Fund which have been or are being offered
for sale (other than the Acquiring Fund Shares to be issued in connection with
the Reorganization) have been duly registered under the Securities Act by the
AGS Registration Statement and have been duly registered, qualified or are
exempt from registration or qualification under the securities laws of each
state or other jurisdiction in which such shares have been or are being offered
for sale, and no action has been taken by AGS to revoke or rescind any such
registration or qualification.

     SECTION 4.6  Accountants. PricewaterhouseCoopers LLP, which has reported

1999, are independent public accountants as required by the Securities Act and
the Exchange Act.

     SECTION 4.7  Binding Obligation. This Agreement has been duly authorized,
executed and delivered by AGS on behalf of the Acquiring Fund and, assuming this
Agreement has been duly executed and delivered by AAF, constitutes the legal,
valid and binding obligation of AGS, enforceable against AGS in accordance with

law or a court of equity and including limitations on the availability of
specific performance or other equitable remedies).

     SECTION 4.8  No Breaches or Defaults. The execution and delivery of this
Agreement by AGS on behalf of the Acquiring Fund and performance by AGS of its
obligations hereunder have been duly authorized by all necessary corporate
action on the part of AGS and (i) do not, and on the Closing Date will not,
result in any violation of the Agreement and Declaration of Trust or by-laws of
AGS and (ii) do not, and on the Closing Date will not, result in a breach of any
of the terms or provisions of, or constitute (with or without the giving of
notice or the lapse of time or both) a default under, or give rise to a right of
termination, cancellation or acceleration of any obligation or to the loss of a
material benefit under, or result in the creation or imposition of any Lien upon
any property or assets of the Acquiring Fund (except for such breaches or
defaults or Liens that would not reasonably be expected, individually or in the
aggregate, to have a Material Adverse Effect) under (A) any indenture, mortgage
or loan agreement or any other material agreement or instrument to which AGS is
a party or by which it may be bound and which relates to the assets of the
Acquiring Fund or to which any properties of the Acquiring Fund may be subject;
(B) any Permit; or (C) any existing applicable law, rule, regulation, judgment,

in a proceeding under Title 11 of the United States Code or similar case within
the meaning of Section 368(a)(3)(A) of the Code.

     SECTION 4.9  Authorizations or Consents. Other than those which shall have
been obtained or made on or prior to the Closing Date, no authorization or
approval or other action by, and no notice to or filing with, any Governmental

due execution and delivery by AGS of this Agreement and the consummation by AGS
of the transactions contemplated hereby.

necessary for it to conduct its business as presently conducted as it relates to
the Acquiring Fund, and there has occurred no default under any Permit, except
for the absence of Permits and for defaults under Permits the absence or default
of which would not reasonably be expected to have, individually or in the
aggregate, a Material Adverse Effect. To the knowledge of AGS there are no
proceedings relating to the suspension, revocation or modification of any
                                      I-11
<PAGE>   42

Permit, except for such that would not reasonably be expected, individually or
in the aggregate, to have a Material Adverse Effect.

     SECTION 4.11  No Actions, Suits or Proceedings. (a) There is no pending
action, suit or proceeding, nor, to the knowledge of AGS, has any litigation
been overtly threatened in writing or, if probable of assertion, orally, against
AGS before any Governmental Authority which questions the validity or legality
of this Agreement or of the transactions contemplated hereby, or which seeks to
prevent the consummation of the transactions contemplated hereby, including the
Reorganization.

     (b) There are no judicial, administrative or arbitration actions, suits, or
proceedings instituted or pending or, to the knowledge of AGS, threatened in
writing or, if probable of assertion, orally, against AGS, affecting any
property, asset, interest or right of the Acquiring Fund, that could reasonably
be expected to have, individually or in the aggregate, a Material Adverse Effect
with respect to the Acquiring Fund. There are not in existence on the date
hereof any plea agreements, judgments, injunctions, consents, decrees,
exceptions or orders that were entered by, filed with or issued by Governmental
Authority relating to AGS's conduct of the business of the Acquiring Fund
affecting in any significant respect the conduct of such business. AGS is not,
and has not been, to the knowledge of AGS, the target of any investigation by
the SEC or any state securities administrator with respect to its conduct of the
business of the Acquiring Fund.

     SECTION 4.12  Taxes. (a) The Acquiring Fund is a "fund" as defined in
Section 851(g)(2) of the Code and has elected to be treated as a regulated
investment company under Subchapter M of the Code. The Acquiring Fund has
qualified for treatment as such for each taxable year since inception that has
ended prior to the Closing Date and will continue to satisfy the requirements of
Part I of Subchapter M of the Code to maintain such qualification for its
current taxable year. The Acquired Fund has no earnings or profits accumulated
in any taxable year in which the provisions of Subchapter M of the Code did not
apply to it.

     (b) The Acquiring Fund has timely filed all Returns required to be filed by
it and all Taxes with respect thereto have been paid, except where the failure
so to file or so to pay, would not reasonably be expected, individually or in
the aggregate, to have a Material Adverse Effect. Adequate provision has been
made in the Acquiring Fund Financial Statements for all Taxes in respect of all
periods ending on or before the date of such financial statements, except where
the failure to make such provisions would not reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect. No
deficiencies for any Taxes have been proposed, assessed or asserted in writing
by any taxing authority against the Acquiring Fund, and no deficiency has been
proposed, assessed or asserted, in writing, where such deficiency would
reasonably be expected, individually or in the aggregate, to have a Material
Adverse Effect. No waivers of the time to assess any such Taxes are outstanding
nor are any written requests for such waivers pending and no Return of the
Acquiring Fund is currently being or has been audited with respect to income
taxes or other Taxes by any Federal, state, local or foreign Tax authority.

purposes since the date on which it commenced operations.

for or on behalf of AGS in connection with this Agreement or the transactions
contemplated hereby, and no broker, finder, agent or similar intermediary is
entitled to any broker's, finder's or similar fee or other commission in
connection therewith based on any agreement, arrangement or understanding with

will it directly or indirectly own, nor has it at any time during the five-year
period ending on the Closing Date directly or indirectly owned, any shares of
the Acquired Fund.

     (b) AGS has no plan or intention to issue additional Acquiring Fund Shares
following the Reorganization except for shares issued in the ordinary course of
Acquiring Fund's business as a series of an open-end investment company; nor
does AGS have any plan or intention to redeem or otherwise reacquire any of the
Acquiring Fund Shares issued in the Reorganization, except to the extent that
the Acquiring Fund

                                      I-12
<PAGE>   43

is required by the Investment Company Act to redeem any of its shares presented
for redemption at net asset value in the ordinary course of its business as a
series of an open-end, management investment company.

     (c) The Acquiring Fund has no plan or intention to sell or otherwise
dispose of any of the Assets other than in the ordinary course of its business
and to the extent necessary to maintain its status as a "regulated investment
company" under the Code.

"historic business" (within the meaning of Section 1.368-1(d)(2) of the Income
Tax Regulations under the Code) of the Acquired Fund and will use a significant
portion of the Acquired Fund's "historic business assets" (within the meaning of
Section 1.368-1(d)(3) of those regulations) in a business.

     (e) There is no plan or intention for the Acquiring Fund to be dissolved or
merged into another business trust or a corporation or any "fund" thereof
(within the meaning of Section 851(g)(2) of the Code) following the
Reorganization.

     SECTION 4.15  Prospectus and Statement of Additional Information. The
current prospectus and statement of additional information for the Acquiring
Fund as of the date on which they were issued did not contain, and as
supplemented by any supplement thereto dated prior to or on the Closing Date do
not contain, any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading.

Shares received by each Acquired Fund Shareholder in the Reorganization will be

constructively surrendered in exchange therefor.

intercompany indebtedness between the Funds that was issued or acquired, or will
be settled, at a discount. No consideration other than the Acquiring Fund Shares
(and the Acquiring Fund's assumption of the Liabilities, including for this
purpose all Liabilities to which the Assets are subject) will be issued in
exchange for the Assets in connection with the Reorganization. The fair market
value of the Assets on a going concern basis will equal or exceed the sum of the
Liabilities to be assumed by the Acquiring Fund plus the amount of Liabilities,
if any, to which the Assets will be subject.

                                  TAX OPINION

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

     (ii) The Acquired Fund will recognize no gain or loss on the transfer of
the Assets to the Acquiring Fund in exchange solely for Acquiring Fund Shares
and the Acquiring Fund's assumption of the Liabilities or on the distribution of
those shares to the Acquired Fund Shareholders.

     (iii) The 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.

     (iv) The Acquiring Fund's basis for the Assets will be the same as the
Acquired Fund's basis therefor immediately before the Reorganization, and the
Acquiring Fund's holding period for the Assets will include the Acquired Fund's
holding period therefor.

     (v) An Acquired Fund Shareholder will recognize no gain or loss on the
receipt of Acquiring Fund Shares in constructive exchange for all its Acquired
Fund Shares pursuant to the Reorganization.

     (vi) An Acquired Fund Shareholder's aggregate basis for the Acquiring Fund
Shares received thereby in the Reorganization will be the same as the aggregate
basis for its Acquired Fund Shares to be constructively surrendered in exchange
therefor, and its holding period for those Acquiring Fund Shares will included
its holding period for those Acquired Fund Shares, provided the Acquired Fund
Shareholder held the Acquired Fund Shares as capital assets at the Effective
Time.

                   CLASS A, CLASS B AND CLASS C SHARES OF

                            AIM BASIC VALUE FUND


                      Supplement dated March 22, 2000
                    to the Prospectus dated May 3, 1999
       as revised October 25, 1999 and supplemented February 11, 2000
                           and February 25, 2000

At a meeting held on March 14, 2000, the Board of Trustees of AIM Growth
Series (the "Trust"), on behalf of AIM Basic Value Fund (the "Fund"), voted
to request shareholders to approve certain proposals relating to the
restructuring of the Fund.

The Fund currently invests all of its investable assets in the Value
Portfolio (the "Portfolio"). The Board approved a restructuring of the Fund
which will eliminate the Fund's current master-feeder structure and cause
the Fund to redeem its interest in the Portfolio. The Portfolio will then
be terminated. The Fund's investment strategies will be the same as the
Portfolio's current investment strategies. The Fund's portfolio managers
will be the current portfolio mangers of the Portfolio. The Board is
requesting shareholder approval of the following items related to the
restructuring:


            -        A new advisory agreement between the Trust and A I M
                     Advisors, Inc. ("AIM"). The Board has concluded that
                     the terms of the new advisory agreement are
                     substantially the same as the advisory portion of the
                     current advisory agreement with the Portfolio, except:
                     (1) AIM would directly manage the Fund's investments
                     and would receive an annual fee for the investment
                     advisory services that it provides to the Fund at a
                     rate equal to the combined rate of the fee charged to
                     the Portfolio and the fee charged to the Fund for
                     administrative services; (2) the proposed advisory
                     agreement adds provisions relating to certain
                     functions that would be performed by AIM in connection
                     with the Fund's securities lending program and for
                     which AIM would receive compensation; and (3) the
                     proposed advisory agreement clarifies non-exclusivity
                     provisions that are set forth in the current advisory
                     agreement;

           -         Changing the Fund's fundamental investment
                     restrictions. The proposed revisions to the Fund's
                     fundamental investment restrictions are described in a
                     supplement to the Fund's statement of additional
                     information;

           -         Making the Fund's investment objective
                     non-fundamental. The investment objective would not be
                     changed. If the investment objective of the Fund
                     becomes non-fundamental, it can be changed in the
                     future by the Board of Trustees of the Trust without
                     further approval by shareholders.

The Board of Trustees of the Trust has called a meeting of the Fund's
shareholders to be held in May 2000 to vote on these and other proposals.
Only shareholders of record as of April 3, 2000 will be entitled to vote at
the meeting. Proposals that are approved are expected to become effective
on or about June 5, 2000.

The Board has also approved a new administrative services agreement between
AIM and the Fund. The administrative and accounting services to be provided
to the Fund are substantially the same services that AIM provides to the
Portfolio and the Fund under the current agreements.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

ANNUAL TOTAL RETURNS

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

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

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

EXPENSE EXAMPLE

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

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

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

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

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

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

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

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

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

CHOOSING A SHARE CLASS

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

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

                                       reinvested dividends and
                                       distributions(1)

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

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

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

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

DISTRIBUTION AND SERVICE (12b-1) FEES

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

SALES CHARGES

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

INITIAL SALES CHARGES

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

CONTINGENT DEFERRED SALES CHARGES FOR CLASS A SHARES

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

CONTINGENT DEFERRED SALES CHARGES FOR
CLASS B AND CLASS C SHARES

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

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

COMPUTING A CDSC

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

REDUCED SALES CHARGES AND SALES CHARGE EXCEPTIONS

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

REDUCED SALES CHARGES

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

Rights of Accumulation

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

Letters of Intent

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

INITIAL SALES CHARGE EXCEPTIONS

You will not pay initial sales charges

- - on shares purchased by reinvesting dividends and distributions;

- - when exchanging shares among certain AIM Funds;

- - when using the reinstatement privilege; and

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

CONTINGENT DEFERRED SALES CHARGE (CDSC) EXCEPTIONS

You will not pay a CDSC

                                 THE AIM FUNDS
                                 -------------

SPECIAL PLANS

AUTOMATIC INVESTMENT PLAN

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

DOLLAR COST AVERAGING

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

AUTOMATIC DIVIDEND INVESTMENT

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

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

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

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

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

PORTFOLIO REBALANCING PROGRAM

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

RETIREMENT PLANS

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

REDEEMING SHARES

REDEMPTION FEES

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

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

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

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

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

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

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

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

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

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

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

                              hours the NYSE is open for business in order to effect the
                              redemption at that day's closing price.

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

TIMING AND METHOD OF PAYMENT

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

REDEMPTION BY MAIL

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

REDEMPTION BY TELEPHONE

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

REDEMPTION BY INTERNET

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

PAYMENT FOR SYSTEMATIC WITHDRAWALS

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

EXPEDITED REDEMPTIONS

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

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

REDEMPTIONS BY CHECK

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

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

SIGNATURE GUARANTEES

We require a signature guarantee when you redeem by mail and

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

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

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

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

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

REINSTATEMENT PRIVILEGE (Class A shares only)

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

REDEMPTIONS BY THE AIM FUNDS

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

  If an AIM Fund determines that you have provided incorrect information in
opening an account or in the course of conducting subsequent transactions, the
AIM Fund may, at its discretion, redeem the account and distribute the proceeds
to you.

EXCHANGING SHARES

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

PERMITTED EXCHANGES

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

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

YOU WILL NOT PAY A SALES CHARGE WHEN EXCHANGING:

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

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

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

EXCHANGES NOT PERMITTED

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

EXCHANGE CONDITIONS

The following conditions apply to all exchanges:

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

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

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

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

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

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

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

TERMS OF EXCHANGE

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

BY MAIL

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

BY TELEPHONE

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

BY INTERNET

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

EXCHANGING CLASS B AND CLASS C SHARES

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

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

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

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

 - REJECT OR CANCEL ANY REQUEST TO ESTABLISH THE AUTOMATIC INVESTMENT PLAN AND
   SYSTEMATIC WITHDRAWAL PLAN OPTIONS ON THE SAME ACCOUNT; OR

 - WITHDRAW ALL OR ANY PART OF THE OFFERING MADE BY THIS PROSPECTUS.

PRICING OF SHARES

DETERMINATION OF NET ASSET VALUE

The price of each AIM Fund's shares is the fund's net asset value per share. The
AIM Funds value portfolio securities for which market quotations are readily
available at market value. The AIM Funds value short-term investments maturing
within 60 days at amortized cost, which approximates market value. AIM Money
Market Fund and AIM Tax-Exempt Cash Fund value all of their securities at
amortized cost. AIM High Income Municipal Fund, AIM Municipal Bond Fund, AIM
Tax-Exempt Bond Fund of Connecticut and AIM Tax-Free Intermediate Fund value
variable rate securities that have an unconditional demand or put feature
exercisable within seven days or less at par, which reflects the market value of
such securities.

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

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

TIMING OF ORDERS

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

TAXES

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

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

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

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

                       ANNUAL REPORT / MANAGERS' OVERVIEW


FUND ENJOYS STELLAR YEAR
DESPITE SHIFTING MARKETS

HOW DID AIM BASIC VALUE FUND PERFORM DURING THE FISCAL YEAR?
For the fiscal year ended December 31, 1999, the fund had total returns of
32.04% for Class A shares, 31.13% for Class B shares and 32.45% for Advisor
Class shares. (These returns are at net asset value, which does not include
sales charges.) The fund finished the reporting period well ahead of both the
Russell 1000 Index and the Lipper Multi-Cap Value Fund Index, which had total
returns of 20.91% and 5.94%, respectively. The fund's performance is
particularly noteworthy given that growth outperformed value on the whole for
1999.
    The fund's Class C shares, which commenced sales on May 3, 1999, had a
cumulative total return of 10.72% through December 31, excluding sales charges.
Total net assets in the fund shot up from $27.5 million a year ago to $136.2
million at the end of the reporting period.

GIVEN THAT GROWTH OUTPERFORMED VALUE DURING 1999, TO WHAT DO YOU ATTRIBUTE THE
FUND'S EXCELLENT PERFORMANCE?
The primary drivers of the fund's performance were technology and energy. Many
investment opportunities during 1999 were created by 1998's financial crisis,
when recession fears drove investors to dump such economically sensitive stocks
as semiconductors and oil services. We took advantage of this situation and
overweighted the fund in both sectors because the stocks were selling at a
significant discount to their intrinsic value and had an attractive long-term
outlook. Value investors who missed these opportunities were left with another
year of underperformance.
    For the second year in a row, value funds as a group underperformed growth
funds by a wide margin. According to Morningstar Inc., a company that tracks
mutual fund performance, the average large growth fund was up 39% for the year,
compared to the average large value fund's return of 7% for the year. This
situation was also reflected in the performance of the Russell 1000 Value Index
vs. the S&P 500 Index, with returns of 7.35% and 21.03%, respectively, for the
year. However, AIM Basic Value Fund bucked this trend, as evidenced by its
performance.

WHAT ELSE HAPPENED IN THE MARKETS DURING THE YEAR?
With the worst of the global financial crisis past, the question throughout much
of 1999 was whether or not the Federal Reserve Board (the Fed) would need to
raise interest rates to forestall inflation. Inflation fears spawned volatility
in the markets, curbing high-flying technology, communications and financial
stocks in the spring and bringing on a resurgence of more cyclical stocks, like
energy and commodities. This environment was quite favorable for the fund.
    By midsummer, major stock indexes reached new record highs, lifted by solid
corporate earnings, continued tame inflation and renewed vitality among tech
stocks. But investors' fears again dampened stocks in general as key economic
indicators showed the economy blazing ahead relentlessly. Consequently, a modest
correction in the third quarter caused the average domestic mutual fund to
decline by about 5.3%. The fund also felt the effects of the correction.
Ultimately, in three separate moves, the Fed raised the key federal funds rate
from 4.75% to 5.50%.
    Despite persistent inflation fears, the U.S. economy continued to experience
a near-record level of consumer confidence. Markets reached a fever pitch by the
end of 1999, with indexes again reaching new highs by the close of the year.
However, these record-breaking performances masked a rather narrow
market--although the S&P 500 returned 14.9% for the fourth quarter, the average
stock in the index was up only 8.2% for the same period.

HOW WAS THE FUND POSITIONED AT THE END OF THE REPORTING PERIOD?
Top sector weightings for the fund at the end of the fiscal year were as
follows: financials, 16.77%; health care, 13.50%; technology, 12.96%; and
energy, 9.21%.

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

                     THE PRIMARY DRIVERS OF THE FUND'S PER-

                      FORMANCE WERE TECHNOLOGY AND ENERGY.

<PAGE>   74
                       ANNUAL REPORT / MANAGERS' OVERVIEW


Our 49 holdings were nearly equally weighted between mid- and large/mega-cap
companies.
    We have been reducing the fund's technology exposure because of excessive
valuations. We think the fundamental outlook for technology is exciting, but
this is against a backdrop of unrealistic expectations, decelerating earnings
growth and accelerating global economic growth. We still believe technology is a
good investment for the long term, but today the best valuation opportunities
are outside technology.
    We continue to find exciting values in the health-care services industry
following the aftermath of the Medicare cuts to balance the federal budget.
Another area of opportunity for the fund is in failed mergers and acquisitions.
In many cases, investors have overreacted to short-term integration problems,
which creates an opportunity for patient investors.

WHAT WERE SOME STANDOUT HOLDINGS FOR THE FUND?
Holdings from several different sectors enhanced the fund's performance.
Citigroup, one of the world's largest financial-services companies, has bounced
back substantially since 1998's global financial crisis eroded its stock along
with those of many other financial companies. Even though health-care stocks
have been in a slump in recent months, top fund holding Health Management
Associates has continued to grow by acquiring and operating hospitals in rural
areas of the southern United States.
    In technology, the fund benefited from owning Computer Associates
International, an independent software company that likens its products to the
plumbing under a sink rather than the fancy faucet on top, and Philips
Electronics, maker of such well-known brands as Magnavox and Norelco and of
everything from televisions to light bulbs to semiconductors.
    One new addition to our list of top holdings since our last report is
Transocean Sedco Forex, an offshore drilling contractor. The company, which
specializes in deepwater drilling, was formed in 1999 when Transocean Offshore
merged with Sedco Forex, a former division of oil giant Schlumberger (also a
fund holding).

WHAT IS YOUR NEAR-TERM OUTLOOK?
Many analysts expect the fast pace of U.S. economic growth to continue through
at least the first half of 2000. This has led to the belief that the Fed will
need to raise interest rates at least once--if not more--to slow economic growth
to a more sustainable pace. It seems that the same story that dogged markets in
1999 is so far continuing, with persistent upward pressure on interest rates.
    We expect accelerating global economic growth to bring with it broader
earnings growth. With earnings growth spread more evenly across the U.S.
economy, a broader stock market should follow. If this happens, we believe value
investing will once again prove to be a market-beating investment strategy. We
continue to find attractive valuation opportunities, and we feel the portfolio
is well positioned going forward.

ABOUT THIS CHART
The chart compares your fund's Class A, Class B and Advisor Class shares to
benchmark indexes. It is intended to give you an idea of how your fund performed
compared to these indexes over the period 10/18/95-12/31/99. (Data for these
indexes are for the period 10/31/95-12/31/99.) It is important to understand the
differences between your fund and an index. An index measures the performance of
a hypothetical portfolio. Your fund's total return is shown with the applicable
sales charge, and it includes fund expenses and management fees. A market index
such as the Russell 1000 Index is not managed, incurring 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. An
index of funds such as the Lipper Multi-Cap Value Fund Index includes a number
of mutual funds grouped by investment objective. Each of those funds interprets
that objective differently, and each employs a different management style and
investment strategy.
    Since our last report, AIM Basic Value Fund has elected to use the Russell
1000 Index as its primary benchmark. The fund will no longer measure its
performance against the Russell 1000 Value Index because this index does not
meet SEC guidelines as a broad market index. Because this is the first reporting
period since we have adopted the new index, SEC guidelines require that we
include the old index in the performance comparison above.

The performance of the fund's Class A, Class B, Class C and Advisor Class shares

calculations and descriptions of the indexes cited on this page, please see the
