                                                                 August 25, 2003

Dear Shareholder:

         As you may be aware, AMVESCAP PLC, the parent company of your Fund's
investment advisor, has undertaken an integration initiative for its North
American mutual fund operations. In the first phase of the integration
initiative, A I M Distributors, Inc. became the sole distributor for all INVESCO
Funds and is now distributor for all INVESCO Funds and the AIM Funds (including
your Fund).

         As a result of this integration initiative, the independent trustees of
your Board of Trustees believe that your interests would best be served if the
AIM Funds and the INVESCO Funds had a unified board of directors/trustees. The
attached proxy statement seeks your vote in favor of the persons nominated to
serve as trustees.

         The integration initiative also calls for changing the organizational
structure of the AIM Funds and the INVESCO Funds. To accomplish this goal,
AMVESCAP PLC has recommended that certain series portfolios of AIM Funds with
few portfolios be restructured as new series portfolios of existing Delaware
statutory trusts. Your Board has approved restructuring your Fund as a new
series of an existing Delaware statutory trust. The attached proxy statement
seeks your approval of this restructuring.

         Your vote is important. Please take a moment after reviewing the
enclosed materials to sign and return your proxy card in the enclosed postage
paid return envelope. 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 us by calling (800) 952-3502. You may also vote your shares by telephone
or through a website established for that purpose by following the instructions
that appear on the enclosed proxy card. If we do not hear from you after a
reasonable amount of time, you may receive a telephone call from our proxy
solicitor, Georgeson Shareholder Communications, Inc. reminding you to vote your
shares.

Sincerely,

/s/ Robert H. Graham

                        SPECIAL MEETINGS OF SHAREHOLDERS
                         TO BE HELD ON OCTOBER 21, 2003

                                  INTRODUCTION

         Proposals 1, 2 and 3 that you are being asked to vote on relate to or
result from an integration initiative announced on March 27, 2003, by AMVESCAP
PLC ("AMVESCAP"), the parent company of A I M Advisors, Inc. ("AIM") and INVESCO
Funds Group, Inc. ("INVESCO"), with respect to its North American mutual fund
operations. The primary components of AMVESCAP's integration initiative are:

         -        Using a single distributor for all AMVESCAP mutual funds in
                  the United States, with A I M Distributors, Inc. ("AIM
                  Distributors"), the distributor for the retail mutual funds
                  advised by AIM (the "AIM Funds"), replacing INVESCO
                  Distributors, Inc. as the distributor for the retail mutual
                  funds advised by INVESCO (the "INVESCO Funds") effective July
                  1, 2003.

         -        Integrating back office support and creating a single platform
                  for back office support of AMVESCAP's mutual fund operations
                  in the United States, including such support services as
                  transfer agency and information technology, with the result
                  that shares of the AIM Funds and shares of the INVESCO Funds
                  generally will be able to be exchanged for shares of the same
                  or a similar class of each other.

         -        Rationalizing and streamlining the various AIM Funds and
                  INVESCO Funds, thereby reducing the number of smaller and less
                  efficient funds that compete for limited shareholder assets
                  and consolidating certain funds having similar investment
                  objectives and strategies.

         -        Rationalizing the contractual arrangements for the provision
                  of investment advisory and administrative services to the AIM
                  Funds and the INVESCO Funds, with the objective of having AIM
                  become the investment advisor and administrator for each
                  INVESCO Fund.

         -        Simplifying the organizational structure of the AIM Funds and
                  the INVESCO Funds so that they are all organized as Delaware
                  statutory trusts, using as few entities as practicable.
                  Proposals 2 and 3 relate to this component of AMVESCAP's
                  integration initiative.



         In considering the integration initiative proposed by AMVESCAP, the
directors/trustees of the AIM Funds and the directors of the INVESCO Funds who
are not "interested persons" (as defined in the Investment Company Act of 1940
(the "1940 Act")) of the Funds or their advisors determined that the
shareholders of both the AIM Funds and the INVESCO Funds would benefit if one
set of directors/trustees was responsible for overseeing the operation of both
the AIM Funds and the INVESCO Funds and the services provided by AIM, INVESCO
and their affiliates. Accordingly, these directors/trustees agreed to combine
the separate boards and create a unified board of directors/trustees. Proposal 1
relates to the election of trustees of your Fund.

                INFORMATION ABOUT THE SPECIAL MEETINGS AND VOTING

PROXY STATEMENT

         We are sending you this Proxy Statement and the enclosed proxy card on
behalf of the series portfolios of AIM Advisor Funds and AIM Series Trust (each
a "Trust," and together, the "Trusts") listed above (each a "Fund," and
together, the "Funds") because the Boards of Trustees of the Trusts (the
"Boards") are soliciting your proxy to vote at the Special Meetings of
Shareholders and at any adjournments of the Special Meetings (collectively, the
"Special Meetings"). This Proxy Statement gives you information about the
business to be conducted at the Special Meetings. However, you do not need to
attend a Special Meeting to vote your shares. Instead, you may simply complete,
sign and return the enclosed proxy card or vote by telephone or through a
website established for that purpose.

         The Trusts intend to mail this Proxy Statement, the enclosed Notice of
Special Meetings of Shareholders and the enclosed proxy card on or about August
24, 2003 to all shareholders entitled to vote. Shareholders of record of any
class of a Fund as of the close of business on July 25, 2003 (the "Record Date")
are entitled to vote at the applicable Special Meeting. The number of shares
outstanding of each class of each Fund on the Record Date can be found in
Exhibit A. Each share of a Fund that you own entitles you to one vote on each
proposal set forth in the table below that applies to the Fund (a fractional
share has a fractional vote).

         We have previously sent to shareholders the most recent annual report
for their Fund, including financial statements, and the most recent semiannual
report succeeding the annual report, if any. If you have not received such
report(s) or would like to receive an additional copy, please contact A I M Fund
Services, Inc., P.O. Box 4739, Houston, TX 77210-4739, or call (800) 347-4246.
We will furnish such report(s) free of charge.

         We are holding the Special Meetings at 11 Greenway Plaza, Suite 100,
Houston, Texas 77046-1173 on October 21, 2003, at 3:00 p.m., Central Time.

VOTING IN PERSON

         If you do attend a Special Meeting and wish to vote in person, we will
provide you with a ballot prior to the vote. However, if your shares are held in
the name of your broker, bank or other nominee, you must bring a letter from the
nominee indicating that you are the beneficial owner of the shares on the Record
Date and authorizing you to vote. Please call the applicable Trust at (800)
952-3502 if you plan to attend a Special Meeting.

VOTING BY PROXY

         Whether you plan to attend a Special Meeting or not, we urge you to
complete, sign and date the enclosed proxy card and to return it promptly in the
envelope provided. Returning the proxy card will not affect your right to attend
a Special Meeting and vote.

         If you properly fill in and sign your proxy card and send it to us in
time to vote at the Special Meetings, your "proxy" (the individual named on your
proxy card) will vote your shares as you have directed. If you sign your proxy
card but do not make specific choices, your proxy will vote your shares as
recommended by the Board of your Trust as follows and in accordance with
management's recommendation on other matters:

         -        FOR the election of all 16 nominees for trustees of your
                  Trust.

         -        FOR the proposal to approve an Agreement and Plan of
                  Reorganization (the "AAF Plan") to restructure each series
                  portfolio of AIM Advisor Funds as a new series portfolio of an
                  existing Delaware statutory trust.

         -        FOR the proposal to approve an Agreement and Plan of
                  Reorganization (the "AST Plan") to restructure the sole series
                  portfolio of AIM Series Trust as a new series portfolio of an
                  existing Delaware statutory trust.

                                       3



         Your proxy will have the authority to vote and act on your behalf at
any adjournment of the Special Meetings.

         If you authorize a proxy, you may revoke it at any time before it is
exercised by sending in another proxy card with a later date or by notifying the
applicable Trust's Secretary in writing to the address of such Trust set forth
on the cover page of this Proxy Statement before a Special Meeting that you have
revoked your proxy. In addition, although merely attending a Special Meeting
will not revoke your proxy, if you are present at a Special Meeting you may
withdraw your proxy and vote in person. Shareholders may also transact any other
business not currently contemplated that may properly come before the Special
Meetings in the discretion of the proxies or their substitutes.

VOTING BY TELEPHONE OR THE INTERNET

         You may vote your shares by telephone or through a website established
for that purpose by following the instructions that appear on the proxy card
accompanying this Proxy Statement.

QUORUM REQUIREMENT AND ADJOURNMENT

         A quorum of shareholders is necessary to hold a valid meeting. A quorum
will exist for Proposal 1 for a particular Trust if shareholders entitled to
vote one-third of the issued and outstanding shares of such Trust on the Record
Date are present at the Special Meetings in person or by proxy. A quorum will
exist for Proposals 2 and 3 for a particular Fund if shareholders entitled to
vote one-third of the issued and outstanding shares of such Fund on the Record
Date are present at the Special Meetings in person or by proxy.

         Under the rules applicable to broker-dealers, if your broker holds your
shares in its name, the broker will be entitled to vote your shares even if it
has not received instructions from you. A "broker non-vote" occurs when a broker
has not received voting instructions from a shareholder and is barred from
voting the shares without shareholder instructions because the proposal is
non-routine.

         Abstentions and broker non-votes will count as shares present at the
Special Meetings for purposes of establishing a quorum.

         If a quorum is not present at a Special Meeting or a quorum is present
but sufficient votes to approve a Proposal are not received, the persons named
as proxies may propose one or more adjournments of the Special Meeting to permit
further solicitation of proxies. Any such adjournment will require the
affirmative vote of a majority of those shares represented at the Special
Meeting in person or by proxy. The persons named as proxies will vote those
proxies that they are entitled to vote FOR a Proposal in favor of such an
adjournment and will vote those proxies required to be voted AGAINST such
Proposal against such an adjournment. A shareholder vote may be taken on a
Proposal in this Proxy Statement prior to any such adjournment if sufficient
votes have been received and it is otherwise appropriate.

VOTE NECESSARY TO APPROVE EACH PROPOSAL

         PROPOSAL 1. The affirmative vote of a plurality of votes cast by the
shareholders of a Trust is necessary to elect trustees of that Trust at a
Special Meeting, meaning that the trustee nominee with the most affirmative
votes for a particular slot is elected for that slot. In an uncontested election
for trustees, the plurality requirement is not a factor. Abstentions will not
count as votes cast and will have no effect on the outcome of this proposal. We
expect that

                                       4



brokers will be entitled to vote on this proposal, but any broker non-vote will
have no effect on the outcome of this proposal.

         PROPOSAL 2. Approval of Proposal 2 with respect to AIM Real Estate Fund
requires the affirmative vote of a majority of the votes cast by shareholders of
AIM Real Estate Fund at its Special Meeting. Abstentions and broker non-votes
will not count as votes cast and will have no effect on the outcome of this
proposal.

         PROPOSAL 3. Approval of Proposal 3 with respect to AIM Global Trends
Fund requires the affirmative vote of a majority of the votes cast by
shareholders of AIM Global Trends Fund at its Special Meeting. Abstentions and
broker non-votes will not count as votes cast and will have no effect on the
outcome of this proposal.

PROXY SOLICITATION

         The Trusts have engaged the services of Georgeson Shareholder
Communications, Inc. ("Solicitor") to assist in the solicitation of proxies for
the Special Meetings. Solicitor's costs are estimated to be approximately
$93,600. The Trusts expect to solicit proxies principally by mail, but the
Trusts or Solicitor may also solicit proxies by telephone, facsimile or personal
interview. The Trusts' officers will not receive any additional or special
compensation for any such solicitation. Each Fund will pay for its proportionate
share of the cost of soliciting proxies, the printing and mailing of this Proxy
Statement, the attached Notice of Special Meetings of Shareholders, the enclosed
proxy card, and any further solicitation.

OTHER MATTERS

         Management does not know of any matters to be presented at the Special
Meetings other than those discussed in this Proxy Statement. If any other
matters properly come before the Special Meetings, the shares represented by
proxies will be voted with respect thereto in accordance with management's
recommendation.

SHAREHOLDER PROPOSALS

         As a general matter, the Funds do not hold regular meetings of
shareholders. If you wish to submit a proposal for consideration at a meeting of
shareholders of your Fund, you should send such proposal to the applicable Trust
at the address set forth on the first page of this Proxy Statement. To be
considered for presentation at a meeting of shareholders, the applicable Trust
must receive proposals a reasonable time before proxy materials are prepared for
the meeting. Your proposal also must comply with applicable law.

         For a discussion of procedures that you must follow if you want to
propose an individual for nomination as a trustee, please refer to the section
of this Proxy Statement entitled "Proposal 1 - Committees of the Board -
Committee on Directors/Trustees."

                                  PROPOSAL 1 -
                              ELECTION OF TRUSTEES

WHICH FUNDS' SHAREHOLDERS WILL VOTE ON PROPOSAL 1?

         Proposal 1 applies to the shareholders of all Funds.

BACKGROUND

         In considering the integration initiative proposed by AMVESCAP, the
independent directors/trustees of the AIM Funds and the independent directors of
the INVESCO Funds determined that the shareholders of all the AIM Funds and the
INVESCO Funds would benefit if a unified board of directors/trustees was
responsible for overseeing the operation of both the AIM Funds and the INVESCO
Funds and the services provided by AIM, INVESCO and their affiliates.
Accordingly, the Board of Directors/Trustees of the AIM Funds and the Boards of
Directors of the INVESCO Funds agreed to combine the separate boards and create
a unified board of directors/trustees.

STRUCTURE OF THE BOARD OF TRUSTEES

         Each Board currently consists of 12 persons. Ten of the current
trustees are "independent," meaning they are not "interested persons" of the
Trusts within the meaning of the 1940 Act. Two of the current trustees are
"interested persons" because of their business and financial relationships with
the Trusts and AIM, each Trust's investment advisor, and/or AIM's parent,
AMVESCAP.

NOMINEES FOR TRUSTEES

         Each Trust's Committee on Directors/Trustees (which consists solely of
independent trustees) has approved the nomination of each of the 12 current
trustees, as set forth below, to serve as trustee until his or her successor is
elected and qualified. In addition, each Trust's Committee on Directors/Trustees
has approved the nomination of four new nominees, as set forth below, to serve
as trustee until his or her successor is elected and qualified. These four new
nominees were nominated to effect as a result of the proposed combination of the
Boards of Directors/Trustees of the AIM Funds and the Boards of Directors of the
INVESCO Funds.

         Each nominee who is a current trustee serves as a director or trustee
of the 17 registered investment companies comprising the AIM Funds. Each nominee
who is a current trustee oversees 86 portfolios that comprise the AIM Funds. The
business address of each nominee who is a current trustee is 11 Greenway Plaza,
Suite 100, Houston, Texas 77046-1173.

         Each new nominee serves as a director of ten registered investment
companies comprising the INVESCO Funds. Each new nominee currently oversees 46
portfolios which comprise the INVESCO Funds. The business address of each new
nominee is 4350 South Monaco Street, Denver, Colorado 80237.

         If elected, each nominee would oversee a total of 27 registered
investment companies currently comprising 132 portfolios.

TRUSTEE'S COMPENSATION

         Each trustee who is not affiliated with AIM is compensated for his or
her services according to a fee schedule which recognizes the fact that such
trustee also serves as a director or trustee of other AIM Funds. Each such
trustee receives a fee, allocated among the AIM Funds for which he or she serves
as a director or trustee, which consists of an annual retainer component and a
meeting fee component.

         Information regarding compensation paid or accrued for each trustee of
the Trusts who was not affiliated with AIM during the year ended December 31,
2002 is found in Exhibit B.

RETIREMENT PLAN FOR TRUSTEES

         The trustees have adopted a retirement plan for the trustees of the
Trusts who are not affiliated with AIM. The retirement plan includes a
retirement policy as well as retirement benefits for the non-AIM-affiliated
trustees.

         The retirement policy permits each non-AIM-affiliated trustee to serve
until December 31 of the year in which the trustee turns 72. A majority of the
trustees may extend from time to time the retirement date of a trustee.

         Annual retirement benefits are available to each non-AIM-affiliated
trustee of the Trusts and/or the other AIM Funds (each, a "Covered Fund") who
has at least five years of credited service as a trustee (including service to a
predecessor fund) for a Covered Fund. The retirement benefits will equal 75% of
the trustee's annual retainer paid or accrued by any Covered Fund to such
trustee during the twelve-month period prior to retirement, including the amount
of any retainer deferred under a separate deferred compensation agreement
between the Covered Fund and the trustee. The annual retirement benefits are
payable in quarterly installments for a number of years equal to the lesser of
(i) ten or (ii) the number of such trustee's credited years of service. A death
benefit is also available under the plan that provides a surviving spouse with a
quarterly installment of 50% of a deceased trustee's retirement benefits for the
same length of

                                       13



time that the trustee would have received the benefits based on his or her
service. A trustee must have attained the age of 65 (55 in the event of death or
disability) to receive any retirement benefit. Payment of benefits under the
plan is not secured or funded by the Trusts.

DEFERRED COMPENSATION AGREEMENTS

         Messrs. Dunn, Fields, Frischling and Sklar and Dr. Mathai-Davis (the
"Deferring Trustees") have each executed a Deferred Compensation Agreement
(collectively, the "Compensation Agreements"). Pursuant to the Compensation
Agreements, the Deferring Trustees have the option to elect to defer receipt of
up to 100% of their compensation payable by the Trusts, and such amounts are
placed into a deferral account. Currently, the Deferring Trustees have the
option to select various AIM Funds in which all or part of their deferral
accounts shall be deemed to be invested. Distributions from the Deferring
Trustees' deferral accounts will be paid in cash, generally in equal quarterly
installments over a period of up to ten (10) years (depending on the
Compensation Agreement) beginning on the date selected under the Compensation
Agreement. Each Board, in its sole discretion, may accelerate or extend the
distribution of such deferral accounts after the Deferring Trustee's retirement
benefits commence under the plan. Each Board, in its sole discretion, also may
accelerate or extend the distribution of such deferral accounts after the
Deferring Trustee's termination of service as a trustee of a Trust. If a
Deferring Trustee dies prior to the distribution of amounts in his or her
deferral account, the balance of the deferral account will be distributed to his
or her designated beneficiary. The Compensation Agreements are not funded and,
with respect to the payments of amounts held in the deferral accounts, the
Deferring Trustees have the status of unsecured creditors of the Trusts and of
each other AIM Fund from which they are deferring compensation.

                                  PROPOSAL 2 -
                            APPROVAL OF THE AAF PLAN
            TO RESTRUCTURE EACH SERIES PORTFOLIO OF AIM ADVISOR FUNDS
          AS A NEW SERIES PORTFOLIO OF AIM INVESTMENT SECURITIES FUNDS

WHICH FUNDS' SHAREHOLDERS WILL VOTE ON PROPOSAL 2?

         Proposal 2 applies only to the shareholders of AIM Real Estate Fund.

BACKGROUND

         AIM Advisor Funds ("AAF"), a Delaware statutory trust, currently is
comprised of two series portfolios: AIM International Core Equity Fund and AIM
Real Estate Fund. AMVESCAP has identified these two series portfolios as
appropriate to be restructured as new series portfolios of AIM Investment
Securities Funds, an existing open-end management investment company organized
as a statutory trust under the Delaware Statutory Trust Act ("AIS").

         AAF's Board of Trustees (the "AAF Board") has approved the AAF Plan,
which provides for a series of transactions to restructure each of AIM
International Core Equity Fund and AIM Real Estate Fund (each, a "Current Fund")
as a corresponding series (a "New Fund") of AIS. Under the AAF Plan, each
Current Fund will transfer all of its assets to a corresponding New Fund in
exchange solely for voting shares of beneficial interest in the New Fund and the
New Fund's assumption of all of the Current Fund's liabilities (collectively,
the "AAF

                                       14



Restructuring"). A form of the AAF Plan relating to the proposed AAF
Restructuring is set forth in Appendix I.

         Approval of the AAF Plan with respect to each Current Fund requires the
affirmative vote of a majority of the votes cast by the shareholders of that
Current Fund on Proposal 2. The Board is soliciting the proxies of the
shareholders of AIM Real Estate Fund to vote on the AAF Plan with this Proxy
Statement. The Board is soliciting the proxies of the shareholders of AIM
International Core Equity Fund to vote on the AAF Plan with a separate proxy
statement.

REASONS FOR THE PROPOSED AAF RESTRUCTURING

         The AAF Restructuring is being proposed to simplify the organizational
structure and reduce the costs of the AIM Funds. The operations of each New Fund
following the AAF Restructuring will be substantially similar to those of its
predecessor Current Fund. Restructuring each Current Fund as a New Fund of AIS
will have the effect of consolidating the record-keeping, accounting, financial
reporting and securities law compliance in a single investment company, which
will in turn create greater operating efficiencies for the AIM Funds. AIS, like
AAF, operates as an open-end management investment company registered with the
SEC under the 1940 Act.

WHAT THE PROPOSED AAF RESTRUCTURING WILL INVOLVE

         To accomplish the AAF Restructuring, each New Fund has been established
as a series portfolio of AIS. On the closing date, each Current Fund will
transfer all of its assets to the corresponding classes of the corresponding New
Fund in exchange solely for a number of full and fractional classes of shares of
the New Fund equal to the number of full and fractional shares of beneficial
interest of the corresponding classes of the Current Fund then outstanding and
the New Fund's assumption of the Current Fund's liabilities. Immediately
thereafter, each Current Fund will distribute those New Fund shares to its
shareholders in complete liquidation of such Current Fund. Upon completion of
the AAF Restructuring, each shareholder of each Current Fund will be the owner
of full and fractional shares of the corresponding New Fund equal in number and
aggregate net asset value to the shares he or she held in the Current Fund. As
soon as practicable after the consummation of the AAF Restructuring, each
Current Fund will be terminated as a designated series of AAF and AAF will be
terminated as a Delaware statutory trust.

         The obligations of AAF and AIS under the AAF Plan are subject to
various conditions stated therein. To provide against unforeseen events, the AAF
Plan may be terminated or amended at any time prior to the closing of the AAF
Restructuring by action of the AAF Board, notwithstanding the approval of the
AAF Plan by the shareholders of either Current Fund. However, no amendments may
be made that would materially adversely affect the interests of shareholders of
either Current Fund. AAF and AIS may at any time waive compliance with any
condition contained in the AAF Plan, provided that the waiver does not
materially adversely affect the interests of shareholders of either Current
Fund.

         The AAF Plan authorizes AAF to acquire one share of each class of each
New Fund and, as the sole shareholder of each New Fund prior to the AAF
Restructuring, to do each of the following:

                                       15



         -        Approve with respect to each New Fund a new investment
                  advisory agreement with AIM that will be substantially
                  identical to AAF's existing investment advisory agreement with
                  AIM.

         -        Approve with respect to AIM International Core Equity Fund a
                  new sub-advisory agreement between AIM and INVESCO Global
                  Asset Management (N.A.), Inc. that will be substantially
                  identical to the existing sub-advisory agreement between AIM
                  and INVESCO Global Asset Management (N.A.), Inc.

         -        Approve with respect to each New Fund a new administrative
                  services agreement with AIM that will be substantially
                  identical to AAF's existing administrative services agreement
                  with AIM.

         -        Approve with respect to each New Fund a distribution agreement
                  with AIM Distributors. The proposed distribution agreement
                  will provide for substantially identical distribution services
                  as currently provided to each corresponding Current Fund by
                  AIM Distributors.

         -        Approve a distribution plan pursuant to Rule 12b-1 under the
                  1940 Act with respect to each class of each New Fund that will
                  be substantially identical to the corresponding Current Fund's
                  existing distribution plan for that class.

         -        Approve with respect to each New Fund a custodian agreement
                  with State Street Bank and Trust Company and a transfer agency
                  and servicing agreement with A I M Fund Services, Inc., each
                  of which currently provides such services to the corresponding
                  Current Fund, and a multiple class plan pursuant to Rule 18f-3
                  of the 1940 Act which will be substantially identical to the
                  multiple class plan that exists for the corresponding Current
                  Fund.

         -        Ratify the selection of Ernst & Young LLP, the accountants for
                  each Current Fund, as the independent public accountants for
                  each New Fund.

         -        Approve such other agreements and plans as are necessary for
                  each New Fund's operation as a series of an open-end
                  management investment company.

         AIS's transfer agent will establish for each shareholder an account
containing the appropriate number of shares of each class of each New Fund. Such
accounts will be identical in all respects to the accounts currently maintained
by AAF's transfer agent for each shareholder of the Current Funds. Shares held
in Current Fund accounts will automatically be designated as shares of the New
Funds. Certificates for Current Fund shares issued before the AAF Restructuring
will represent shares of the corresponding New Fund after the AAF Restructuring.
Shareholders of the New Funds will not have the right to demand or require AIS
to issue share certificates. Any account options or privileges on accounts of
shareholders under the Current Funds will be replicated on the New Fund account.
No sales charges will be imposed in connection with the AAF Restructuring.

         Assuming your approval of Proposal 2, AAF currently contemplates that
the AAF Restructuring will be consummated on October 29, 2003.

                                       16



THE FEDERAL INCOME TAX CONSEQUENCES OF THE AAF RESTRUCTURING

         AAF and AIS will receive an opinion of Ballard Spahr Andrews &
Ingersoll, LLP to the effect that the AAF Restructuring will qualify as a
"reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended. Accordingly, the Current Funds, the New Funds and the
shareholders of the New Funds will recognize no gain or loss for Federal income
tax purposes as a result of the AAF Restructuring. Shareholders of the Current
Funds should consult their tax advisers regarding the effect, if any, of the AAF
Restructuring in light of their individual circumstances and as to state and
local consequences, if any, of the AAF Restructuring.

APPRAISAL RIGHTS

         Appraisal rights are not available to shareholders. However,
shareholders retain the right to redeem their shares of the Current Funds or the
New Funds, as the case may be, at any time before or after the AAF
Restructuring.

AIS COMPARED TO AAF

         General

         AIS and AAF are both Delaware statutory trusts. The operations of AIS
and AAF, as Delaware statutory trusts, are governed by the terms of their
respective Declarations of Trust, Amended and Restated Bylaws and applicable
Delaware law.

         Structure of AIS

         AIS is an existing statutory trust established under the laws of the
State of Delaware by the filing of a certificate of trust in the office of the
Secretary of State of Delaware. AIS has established new series portfolios
corresponding to and having identical designations as the series portfolios of
AAF. AIS has also established classes with respect to each New Fund
corresponding to and having identical designations as the classes of each
Current Fund. Each New Fund will have the same investment objectives, policies,
and restrictions as its predecessor Current Fund. AIS's fiscal year is the same
as that of AAF. No New Fund will have any operations prior to the AAF
Restructuring. Initially, AAF will be the sole shareholder of each New Fund.

         As a Delaware statutory trust, AIS's operations are governed by its
Amended and Restated Agreement and Declaration of Trust, as amended (the "AIS
Declaration"), Amended and Restated Bylaws and applicable Delaware law. Certain
issues relating to the form of organization of both AIS and AAF are summarized
below. The operations of AIS will continue to be subject to the provisions of
the 1940 Act and the rules and regulations thereunder.

                                       17



         Trustees and Officers of AIS

         Subject to the provisions of the AIS Declaration, the business of AIS
will be managed by its trustees, who have all powers necessary or convenient to
carry out their responsibilities. The responsibilities, powers, and fiduciary
duties of the trustees of AIS and AAF are identical to one another.

         Certain of the current officers of AAF currently serve as officers of
AIS and those current officers of AAF will perform the same functions on behalf
of the New Funds and AIS following the AAF Restructuring that they now perform
on behalf of AIM Real Estate Fund and AAF.

         Shares of AIS

         The beneficial interests in the New Funds will be represented by
transferable shares, par value $0.01 per share. Shareholders do not have the
right to demand or require AIS to issue share certificates. The trustees have
the power under the AIS Declaration to establish new series and classes of
shares. The AIS Declaration permits the trustees to issue an unlimited number of
shares of each class and series.

         AIM Real Estate Fund currently has the classes of shares set forth in
Exhibit A. AIS has established for each New Fund the classes that currently
exist for its predecessor Current Fund. Except as discussed in this Proxy
Statement, shares of each class of each New Fund will have rights, privileges,
and terms substantially similar to those of the corresponding class of the
Current Fund.

         Liability of Shareholders

         The Delaware Statutory Trust Act provides that shareholders of a
Delaware statutory 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 statutory trust might be held personally liable for the trust's
obligations to the extent the courts of another state that does not recognize
such limited liability were to apply the laws of such state to a controversy
involving such obligations. The AIS Declaration and the AAF Amended and Restated
Agreement and Declaration of Trust, as amended, (the "AAF Declaration" and
together with the AIS Declaration, the "Declarations of Trust") provide that
shareholders of AAF and AIS, as applicable, shall not be subject to any personal
liability for acts or obligations of AAF and AIS and that every written
agreement, obligation or other undertaking made or issued by AAF and AIS, shall
contain a provision to the effect that shareholders are not personally liable
thereunder. In addition, the Declarations of Trust provide for indemnification
out of the property of AAF and AIS, as applicable, 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 or her investment due to shareholder liability is limited to
circumstances in which AAF and AIS, 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 AAF and AIS, the
possibility of AAF and AIS, as applicable, being unable to meet their
obligations is considered remote, and even if a claim were brought against AAF
or AIS, and a court determined that shareholders were personally liable, it
would likely not impose a material obligation on a shareholder.

                                       18



         Election of Trustees; Terms

         The shareholders of each of AAF and AIS have elected a majority of the
trustees of AAF and AIS respectively. Such trustees serve for the life of AAF
and AIS, subject to their earlier death, incapacitation, resignation, retirement
or removal (see below). In the case of any vacancy on the AAF Board or the AIS's
Board of Trustees (the "AIS Board" and together with the AAF Board, the "Boards
of Trustees"), a majority of the trustees may appoint a successor to fill such
vacancy. The right of the Boards of Trustees to appoint trustees to fill
vacancies without shareholder approval is subject to the provisions of the 1940
Act.

         Removal of Trustees

         A trustee of AAF and AIS may be removed at any time by a written
instrument signed by at least two-thirds of the trustees or by vote of
two-thirds of the outstanding shares of AAF and AIS, respectively.

         Meetings of Shareholders

         AAF and AIS are not required to hold annual meetings of shareholders
unless required by the 1940 Act and do not intend to do so. The bylaws of each
of AAF and AIS provide that any trustee may call a special meeting of
shareholders and the trustees shall call a special meeting of the shareholders
solely for the purpose of removing one or more trustees upon written request of
the holders of not less than 10% of the outstanding shares of AAF and AIS, as
applicable. 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.

         Liability of Trustees and Officers; Indemnification

         Delaware law provides that trustees of a statutory trust shall not be
liable to the statutory trust or its shareholders for acting in good faith
reliance on the provisions of its governing instrument and that the trustee's
liabilities may be expanded or restricted by such instrument. Under the
Declarations of Trust, the trustees and officers of AAF and AIS 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 statutory trust to
indemnify and hold harmless any trustee or other person against any and all
claims and demands. The Declarations of Trust provide for the indemnification of
their respective trustees and officers to the extent that such trustees and
officers act in good faith and reasonably believe that their conduct is in the
best interests of such trust, except with respect to any matter in which it has
been determined that such trustee acted with willful misfeasance, bad faith,
gross negligence or reckless disregard of his or her duties.

         Termination

         Pursuant to the Declarations of Trust, each of AAF and AIS or any
series or class of shares of beneficial interest in such trust may be terminated
by: (1) a majority shareholder vote of such trust or the affected series or
class, or (2) if there are fewer than 100 shareholders of record of such trust
or of such terminating series or class, the trustees pursuant to written notice
to the shareholders of such trust or the affected series or class.

                                       19



         Voting Rights of Shareholders

         The Declarations of Trust grant shareholders power to vote only with
respect to the following: (i) election of trustees, provided that a meeting of
shareholders has been called for that purpose; (ii) removal of trustees,
provided that a meeting of shareholders has been called for that purpose; (iii)
termination of such trust or a series or class of its shares of beneficial
interest, provided that a meeting of shareholders has been called for that
purpose; (iv) sale of all or substantially all of the assets of such trust or
one of its investment portfolios; (v) merger or consolidation of such trust or
any of its investment portfolios, with certain exceptions; (vi) approval of any
amendments to shareholders' voting rights under such Declarations of Trust; and
(vii) approval of such additional matters as may be required by law or as the
trustees, in their sole discretion, shall determine.

         Dissenters' Rights

         Neither Delaware law nor the Declarations of Trust confer upon
shareholders rights of appraisal or dissenters' rights.

         Amendments to Organization Documents

         Consistent with Delaware law, the Boards of Trustees may, without
shareholder approval, amend their respective Declarations of Trust at any time,
except to eliminate any voting rights pertaining to the shares of such trust,
without approval of the majority of the shares of such trust. The trustees shall
have the power to alter, amend or repeal the bylaws of such trust or adopt new
bylaws at any time.

         The foregoing discussion is only a summary of certain of the issues
relating to the form of organization of both AIS and AAF. Shareholders should
refer to the provisions of the governing documents of AIS and AAF documents and
state law directly for more details. Copies of the Declarations of Trust and the
Amended and Restated Bylaws of AAF and AIS are available to shareholders without
charge upon written request to AAF.

THE BOARD'S RECOMMENDATION ON PROPOSAL 2

         Your Board, including the independent trustees, unanimously recommends
that you vote "FOR" this Proposal.

                                  PROPOSAL 3 -
                            APPROVAL OF THE AST PLAN
          TO RESTRUCTURE THE SOLE SERIES PORTFOLIO OF AIM SERIES TRUST
                 AS A NEW SERIES PORTFOLIO OF AIM GROWTH SERIES

WHICH FUNDS' SHAREHOLDERS WILL VOTE ON PROPOSAL 3?

         Proposal 3 applies only to the shareholders of AIM Global Trends Fund.

BACKGROUND

         AIM Series Trust ("AST"), a Delaware statutory trust, currently is
comprised of one series portfolio: AIM Global Trends Fund. AMVESCAP has
identified this series portfolio as appropriate to be restructured as a new
series portfolio of AIM Growth Series, an existing open-end

                                       20




management investment company organized as a statutory trust under the Delaware
Statutory Trust Act ("AGS").

         AST's Board of Trustees (the "AST Board") has approved the AST Plan,
which provides for a series of transactions to restructure AIM Global Trends
Fund (the "Current Fund") as a corresponding series (the "New Fund") of AGS.
Under the AST Plan, the Current Fund will transfer all of its assets to the New
Fund in exchange solely for voting shares of beneficial interest in the New Fund
and the New Fund's assumption of all the Current Fund's liabilities
(collectively, the "AST Restructuring"). A form of the AST Plan relating to the
proposed AST Restructuring is set forth in Appendix I.

         Approval of the AST Plan requires the affirmative vote of a majority of
the votes cast by the shareholders of the Current Fund on Proposal 3.

REASONS FOR THE PROPOSED AST RESTRUCTURING

         The AST Restructuring is being proposed to simplify the organizational
structure and reduce the costs of the AIM Funds. The operations of the New Fund
following the AST Restructuring will be substantially similar to those of the
predecessor Current Fund. Restructuring the Current Fund as a New Fund of AGS
will have the effect of consolidating the record-keeping, accounting, financial
reporting and securities law compliance in a single investment company, which
will in turn create greater operating efficiencies for the AIM Funds. AGS, like
AST, operates as an open-end management investment company registered with the
SEC under the 1940 Act.

WHAT THE PROPOSED AST RESTRUCTURING WILL INVOLVE

         To accomplish the AST Restructuring, the New Fund has been established
as a series portfolio of AGS. On the closing date, the Current Fund will
transfer all of its assets to the corresponding classes of the New Fund in
exchange solely for a number of full and fractional classes of shares of the New
Fund equal to the number of full and fractional shares of beneficial interest of
the corresponding classes of the Current Fund then outstanding and the New
Fund's assumption of the Current Fund's liabilities. Immediately thereafter, the
Current Fund will distribute those New Fund shares to its shareholders in
complete liquidation of the Current Fund. Upon completion of the AST
Restructuring, each shareholder of the Current Fund will be the owner of full
and fractional shares of the New Fund equal in number and aggregate net asset
value to the shares he or she held in the Current Fund. As soon as practicable
after the consummation of the AST Restructuring, the Current Fund will be
terminated as a designated series of AST and AST will be terminated as a
Delaware statutory trust.

         The obligations of AST and AGS under the AST Plan are subject to
various conditions stated therein. To provide against unforeseen events, the AST
Plan may be terminated or amended at any time prior to the closing of the AST
Restructuring by action of the AST Board, notwithstanding the approval of the
AST Plan by the shareholders of the Current Fund. However, no amendments may be
made that would materially adversely affect the interests of shareholders of the
Current Fund. AST and AGS may at any time waive compliance with any condition
contained in the AST Plan, provided that the waiver does not materially
adversely affect the interests of shareholders of the Current Fund.

                                       21



         The AST Plan authorizes AST to acquire one share of each class of the
New Fund and, as the sole shareholder of the New Fund prior to the AST
Restructuring, to do each of the following:

         -        Approve with respect to the New Fund a new investment advisory
                  agreement with AIM that will be substantially identical to
                  AST's existing investment advisory agreement with AIM.

         -        Approve with respect to the New Fund a new administrative
                  services agreement with AIM that will be substantially
                  identical to AST's existing administrative services agreement
                  with AIM.

         -        Approve with respect to the New Fund a distribution agreement
                  with AIM Distributors. The proposed distribution agreement
                  will provide for substantially identical distribution services
                  as currently provided to the Current Fund by AIM Distributors.

         -        Approve a distribution plan pursuant to Rule 12b-1 under the
                  1940 Act with respect to each class of the New Fund that will
                  be substantially identical to the Current Fund's existing
                  distribution plan for that class.

         -        Approve with respect to the New Fund a custodian agreement
                  with State Street Bank and Trust Company and a transfer agency
                  and servicing agreement with A I M Fund Services, Inc., each
                  of which currently provides such services to the Current Fund,
                  and a multiple class plan pursuant to Rule 18f-3 of the 1940
                  Act which will be substantially identical to the multiple
                  class plan that exists for the Current Fund.

         -        Ratify the selection of PricewaterhouseCoopers LLP, the
                  accountants for the Current Fund, as the independent public
                  accountants for the New Fund.

         -        Approve such other agreements and plans as are necessary for
                  the New Fund's operation as a series of an open-end management
                  investment company.

         AGS's transfer agent will establish for each shareholder an account
containing the appropriate number of shares of each class of the New Fund. Such
accounts will be identical in all respects to the accounts currently maintained
by AST's transfer agent for each shareholder of the Current Fund. Shares held in
Current Fund accounts will automatically be designated as shares of the New
Fund. Certificates for Current Fund shares issued before the AST Restructuring
will represent shares of the New Fund after the AST Restructuring. Shareholders
of the New Fund will not have the right to demand or require AGS to issue share
certificates. Any account options or privileges on accounts of shareholders
under the Current Fund will be replicated on the New Fund account. No sales
charges will be imposed in connection with the AST Restructuring.

         Assuming your approval of Proposal 3, AST currently contemplates that
the AST Restructuring will be consummated on November 4, 2003.

                                       22



THE FEDERAL INCOME TAX CONSEQUENCES OF THE AST RESTRUCTURING

         AST and AGS will receive an opinion of Ballard Spahr Andrews &
Ingersoll, LLP to the effect that the AST Restructuring will qualify as a
"reorganization" within the meaning of Section 368(a) of the Internal Revenue
Code of 1986, as amended. Accordingly, the Current Fund, the New Fund and the
shareholders of the New Fund will recognize no gain or loss for Federal income
tax purposes as a result of the AST Restructuring. Shareholders of the Current
Fund should consult their tax advisers regarding the effect, if any, of the AST
Restructuring in light of their individual circumstances and as to state and
local consequences, if any, of the AST Restructuring.

APPRAISAL RIGHTS

         Appraisal rights are not available to shareholders. However,
shareholders retain the right to redeem their shares of the Current Fund or the
New Fund, as the case may be, at any time before or after the AST Restructuring.

AGS COMPARED TO AST

         General

         AGS and AST are both Delaware statutory trusts. The operations of AGS
and AST, as Delaware statutory trusts, are governed by the terms of their
respective Declarations of Trust, Amended and Restated Bylaws and applicable
Delaware law.

         Structure of AGS

         AGS is an existing statutory trust established under the laws of the
State of Delaware by the filing of a certificate of trust in the office of the
Secretary of State of Delaware. AGS has established a new series portfolio
corresponding to and having identical designations as the series portfolio of
AST. AGS has also established classes with respect to the New Fund corresponding
to and having identical designations as the classes of the Current Fund. The New
Fund will have the same investment objectives, policies, and restrictions as the
predecessor Current Fund. AGS's fiscal year is the same as that of AST. The New
Fund will not have any operations prior to the AST Restructuring. Initially, AST
will be the sole shareholder of the New Fund.

         As a Delaware statutory trust, AGS's operations are governed by its
Amended and Restated Agreement and Declaration of Trust, as amended (the "AGS
Declaration"), Amended and Restated Bylaws and applicable Delaware law. Certain
issues relating to the form of organization of both AGS and AST are summarized
below. The operations of AGS will continue to be subject to the provisions of
the 1940 Act and the rules and regulations thereunder.

                                       23



         Trustees and Officers of AGS

         Subject to the provisions of the AGS Declaration, the business of AGS
will be managed by its trustees, who have all powers necessary or convenient to
carry out their responsibilities. The responsibilities, powers, and fiduciary
duties of the trustees of AGS and AST are identical to one another.

         All of the current officers of AST currently serve as officers of AGS
and those current officers of AST will perform the same functions on behalf of
the New Fund and AGS following the AST Restructuring that they now perform on
behalf of AIM Global Trends Fund and AST.

         Shares of AGS

         The beneficial interests in the New Fund will be represented by
transferable shares, par value $0.01 per share. Shareholders do not have the
right to demand or require AGS to issue share certificates. The trustees have
the power under the AGS Declaration to establish new series and classes of
shares. The AGS Declaration permits the trustees to issue an unlimited number of
shares of each class and series.

         AIM Global Trends Fund currently has the classes of shares set forth in
Exhibit A. AGS has established for the New Fund the classes that currently exist
for the predecessor Current Fund. Except as discussed in this Proxy Statement,
shares of each class of the New Fund will have rights, privileges, and terms
substantially similar to those of the corresponding class of the Current Fund.

         Liability of Shareholders

         The Delaware Statutory Trust Act provides that shareholders of a
Delaware statutory 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 statutory trust might be held personally liable for the trust's
obligations to the extent the courts of another state that does not recognize
such limited liability were to apply the laws of such state to a controversy
involving such obligations. The AGS Declaration and AST's Amended and Restated
Agreement and Declaration of Trust, as amended (the "AST Declaration" and
together with the AGS Declaration, the "Declarations of Trust") provide that
shareholders of AST and AGS, as applicable, shall not be subject to any personal
liability for acts or obligations of AST and AGS and that every written
agreement, obligation or other undertaking made or issued by AST and AGS, shall
contain a provision to the effect that shareholders are not personally liable
thereunder. In addition, the Declarations of Trust provide for indemnification
out of the property of AST and AGS, as applicable, 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 or her investment due to shareholder liability is limited to
circumstances in which AST and AGS, 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 AST and AGS, the
possibility of AST and AGS, as applicable, being unable to meet their
obligations is considered remote, and even if a claim were brought against AST
or AGS, and a court determined that shareholders were personally liable, it
would likely not impose a material obligation on a shareholder.

                                       24



         Election of Trustees; Terms

         The shareholders of each of AST and AGS have elected a majority of the
trustees of AST and AGS respectively. Such trustees serve for the life of AST
and AGS, subject to their earlier death, incapacitation, resignation, retirement
or removal (see below). In the case of any vacancy on the AST Board or AGS's
Board of Trustees (the "AGS Board" and together with the AST Board, the "Boards
of Trustees"), a majority of the trustees may appoint a successor to fill such
vacancy. The right of the Boards of Trustees to appoint trustees to fill
vacancies without shareholder approval is subject to the provisions of the 1940
Act.

         Removal of Trustees

         A trustee of AST and AGS may be removed at any time by a written
instrument signed by at least two-thirds of the trustees or by vote of
two-thirds of the outstanding shares of AST and AGS, respectively.

         Meetings of Shareholders

         AST and AGS are not required to hold annual meetings of shareholders
unless required by the 1940 Act and do not intend to do so. The bylaws of each
of AST and AGS provide that any trustee may call a special meeting of
shareholders and the trustees shall call a special meeting of the shareholders
solely for the purpose of removing one or more trustees upon written request of
the holders of not less than 10% of the outstanding shares of AST and AGS, as
applicable. 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.

         Liability of Trustees and Officers; Indemnification

         Delaware law provides that trustees of a statutory trust shall not be
liable to the statutory trust or its shareholders for acting in good faith
reliance on the provisions of its governing instrument and that the trustee's
liabilities may be expanded or restricted by such instrument. Under the
Declarations of Trust, the trustees and officers of AST and AGS are not liable
for any act or omission or any conduct whatsoever in their capacity as trustees,
except for liability to the trust or shareholders due to willful misfeasance,
bad faith, gross negligence or reckless disregard of the duties involved in the
conduct of the office of trustee. Delaware law allows a statutory trust to
indemnify and hold harmless any trustee or other person against any and all
claims and demands. The Declarations of Trust provide for the indemnification of
their respective trustees and officers to the extent that such trustees and
officers act in good faith and reasonably believe that their conduct is in the
best interests of such trust, except with respect to any matter in which it has
been determined that such trustee acted with willful misfeasance, bad faith,
gross negligence or reckless disregard of his or her duties.

         Termination

         Pursuant to the Declarations of Trust, each of AST and AGS or any
series or class of shares of beneficial interest in such trust may be terminated
by: (1) a majority shareholder vote of such trust or the affected series or
class, or (2) if there are fewer than 100 shareholders of record of such trust
or of such terminating series or class, the trustees pursuant to written notice
to the shareholders of such trust or the affected series or class.

                                       25


         Voting Rights of Shareholders

         The Declarations of Trust grant shareholders power to vote only with
respect to the following: (i) election of trustees, provided that a meeting of
shareholders has been called for that purpose;(ii) removal of trustees, provided
that a meeting of shareholders has been called for that purpose; (iii)
termination of such trust or a series or class of its shares of beneficial
interest, provided that a meeting of shareholders has been called for that
purpose; (iv) sale of all or substantially all of the assets of such trust or
one of its investment portfolios; (v) merger or consolidation of such trust or
any of its investment portfolios, with certain exceptions; (vi) approval of any
amendments to shareholders' voting rights under such Declarations of Trust and
(vii) approval of such additional matters as may be required by law or as the
trustees, in their sole discretion, shall determine.

         Dissenters' Rights

         Neither Delaware law nor the Declarations of Trust confer upon
shareholders rights of appraisal or dissenters' rights.

         Amendments to Organization Documents

         Consistent with Delaware law, the Boards of Trustees may, without
shareholder approval, amend their respective Declarations of Trust at any time,
except to eliminate any voting rights pertaining to the shares of such trust,
without approval of the majority of the shares of such trust. The trustees shall
have the power to alter, amend or repeal the bylaws of such trust or adopt new
bylaws at any time.

         The foregoing discussion above is only a summary of certain of the
issues relating to the form of organization of both AST and AGS. Shareholders
should refer to the provisions of the governing documents of AST and AGS and
state law directly for more details. Copies of the Declarations of Trust and the
Amended and Restated Bylaws of AST and AGS are available to shareholders without
charge upon written request to AST.

THE BOARD'S RECOMMENDATION ON PROPOSAL 3

         Your Board, including the independent trustees, unanimously recommends
that you vote "FOR" this Proposal.

                         INDEPENDENT PUBLIC ACCOUNTANTS

         The Audit Committee of the AAF Board has appointed Ernst & Young LLP
("E&Y") as such Trust's independent public accountants for the fiscal year
ending July 31, 2004. The Audit Committee of the AST Board has appointed
PricewaterhouseCoopers LLP ("PwC") as such Trust's independent public
accountants for the 2003 fiscal year ending December 31, 2003.

         The Audit Committees of the AAF Board and the AST Board have considered
whether the provision of the services below is compatible with maintaining the
independence of E&Y and PwC, respectively.

                                   APPENDIX I

                                AIM ADVISOR FUNDS

                      AGREEMENT AND PLAN OF REORGANIZATION

         AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement"), dated as of
July 30, 2003, by and between AIM Advisor Funds, a Delaware statutory trust
("AAF"), acting on its own behalf and on behalf of each of its series
portfolios, all of which are identified on Schedule A to this Agreement, and AIM
Investment Securities Funds, a Delaware statutory trust (the "Trust"), acting on
its own behalf and on behalf of each of its series portfolios, all of which are
identified on Schedule A.

                                   BACKGROUND

         AAF is organized as a series management investment company and is
registered with the Securities and Exchange Commission under the Investment
Company Act of 1940, as amended. AAF currently publicly offers shares of
beneficial interest representing interests in two separate series portfolios.
Each of these two series portfolios is listed on Schedule A and is referred to
in this Agreement as a "Current Fund."

         The Board of Trustees of AAF has designated multiple classes of shares
of beneficial interest that represent interests in each Current Fund. Each of
these classes is listed on Schedule B to this Agreement and is referred to in
this Agreement as a "Current Fund Class."

         The Board of Trustees of AAF has determined that it would be in the
best interests of the shareholders of the Current Funds for the Current Funds to
reorganize as investment portfolios of the Trust. In anticipation of such
reorganization, the Board of Trustees of the Trust has established two
additional series portfolios corresponding to the Current Funds (each a "New
Fund"), and has designated multiple classes of shares of beneficial interest in
each New Fund corresponding to the Current Fund Classes (each a "New Fund
Class"). Schedule A lists the New Funds and Schedule B lists the New Fund
Classes.

         Each Current Fund desires to provide for its reorganization (each, a
"Reorganization" and collectively, the "Reorganizations") through the transfer
of all of its assets to the corresponding New Fund in exchange for the
assumption by such New Fund of the liabilities of the corresponding Current Fund
and the issuance by the Trust to such Current Fund of shares of beneficial
interest in the New Fund ("New Fund Shares"). New Fund Shares received by a
Current Fund will have an aggregate net asset value equal to the aggregate net
asset value of the shares of the Current Fund immediately prior to the
Reorganization (the "Current Fund Shares"). Each Current Fund will then
distribute the New Fund Shares it has received to its shareholders.

         The Reorganization of either Current Fund is not dependent upon the
consummation of the Reorganization of the other Current Fund, so that the
Reorganization of a Current Fund may be consummated even if the Reorganization
of the other Current Fund is not consummated. For convenience, the balance of
this Agreement refers only to a single Reorganization, but the terms and
conditions hereof shall apply separately to each Reorganization and to the
Current Fund and the corresponding New Fund participating therein, as
applicable.

                                      AP-1



         The Reorganization is subject to, and shall be effected in accordance
with, the terms of this Agreement. This Agreement is intended to be and is
adopted by AAF, on its own behalf and on behalf of the Current Funds, and by the
Trust, on its own behalf and on behalf of the New Funds, as a Plan of
Reorganization within the meaning of the regulations under Section 368(a) of the
Internal Revenue Code of 1986, as amended.

2.       PLAN OF REORGANIZATION.

         2.1      AAF agrees, on behalf of each Current Fund, to assign, sell,
convey, transfer and deliver all of the Assets of each Current Fund to its
corresponding New Fund. The Trust, on behalf of each New Fund, agrees in
exchange therefor:

                  (a)      to issue and deliver to the corresponding Current
         Fund the number of full and fractional (rounded to the third decimal
         place) New Fund Shares of each New Fund Class designated on Schedule B
         equal to the number of full and fractional Current Fund Shares of each
         corresponding Current Fund Class designated on Schedule B; and

                  (b)      to assume all of the Current Fund's Liabilities.

Such transactions shall take place at the Closing.

         2.2      At the Effective Time (or as soon thereafter as is reasonably
practicable), (a) the New Fund Shares issued pursuant to Section 5.2 shall be
redeemed by each New Fund for $1.00 and (b) each Current Fund shall distribute
the New Fund Shares received by it pursuant to Section 2.1 to the Current Fund's
Shareholders in exchange for such Shareholders' Current Fund Shares. Such
distribution shall be accomplished through opening accounts, by the transfer
agent for the Trust (the "Transfer Agent"), on each New Fund's share transfer
books in the Shareholders' names and transferring New Fund Shares to such
accounts. Each Shareholder's account shall be credited with the respective pro
rata number of full and fractional (rounded to the third decimal place) New Fund
Shares of each New Fund Class due that Shareholder. All outstanding Current Fund
Shares, including those represented by certificates, shall

                                      AP-3



simultaneously be canceled on each Current Fund's share transfer books. The
Trust shall not issue certificates representing the New Fund Shares in
connection with the Reorganization. However, certificates representing Current
Fund Shares shall represent New Fund Shares after the Reorganization.

         2.3      Following receipt of the required shareholder vote and as soon
as reasonably practicable after the Closing, the status of each Current Fund as
a designated series of AAF shall be terminated.

         2.4      Any transfer taxes payable on issuance of New Fund Shares in a
name other than that of the registered holder of the Current Fund Shares
exchanged therefor shall be paid by the person to whom such New Fund Shares are
to be issued, as a condition of such transfer.

         2.5      Any reporting responsibility of AAF or each Current Fund to a
public authority is and shall remain its responsibility up to and including the
date on which it is terminated.

3.       CLOSING.

         3.1      The Closing shall occur at the principal office of AAF on
October 29, 2003, or on such other date and at such other place upon which the
parties may agree. All acts taking place at the Closing shall be deemed to take
place simultaneously as of AAF's and the Trust's close of business on the date
of the Closing or at such other time as the parties may agree (the "Effective
Time").

         3.2      AAF or its fund accounting agent shall deliver to the Trust at
the Closing, a certificate of an authorized officer verifying that the
information (including adjusted basis and holding period, by lot) concerning the
Assets, including all portfolio securities, transferred by the Current Funds to
the New Funds, as reflected on the New Funds' books immediately following the
Closing, does or will conform to such information on the Current Funds' books
immediately before the Closing. AAF shall cause the custodian for each Current
Fund to deliver at the Closing a certificate of an authorized officer of the
custodian stating that (a) the Assets held by the custodian will be transferred
to each corresponding New Fund at the Effective Time and (b) all necessary taxes
in conjunction with the delivery of the Assets, including all applicable federal
and state stock transfer stamps, if any, have been paid or provision for payment
has been made.

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

                                      AP-4



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

4.       REPRESENTATIONS AND WARRANTIES.

         4.1      AAF represents and warrants on its own behalf and on behalf of
each Current Fund as follows:

                  (a)      AAF is a statutory trust duly organized, validly
         existing, and in good standing under the laws of the State of Delaware,
         and its Certificate of Trust has been duly filed in the Office of the
         Secretary of State of Delaware;

                  (b)      AAF is duly registered as an open-end series
         management investment company under the 1940 Act, and such registration
         is in full force and effect;

                  (c)      Each Current Fund is a duly established and
         designated series of AAF;

                  (d)      At the Closing, each Current Fund will have good and
         marketable title to its Assets and full right, power, and authority to
         sell, assign, transfer, and deliver its Assets free of any liens or
         other encumbrances; and upon delivery and payment for the Assets, the
         corresponding New Fund will acquire good and marketable title to the
         Assets;

                  (e)      The New Fund Shares are not being acquired for the
         purpose of making any distribution thereof, other than in accordance
         with the terms hereof;

                  (f)      Each Current Fund is a "fund" as defined in Section
         851(g)(2) of the Code; each Current Fund qualified for treatment as a
         RIC for each taxable year since it commenced operations that has ended
         (or will end) before the Closing and will continue to meet all the
         requirements for such qualification for its current taxable year (and
         the Assets will be invested at all times through the Effective Time in
         a manner that ensures compliance with the foregoing); each Current Fund
         has no earnings and profits accumulated in any taxable year in which
         the provisions of Subchapter M did not apply to it; and each Current
         Fund has made all distributions for each calendar year that has ended
         (or will end) before the Closing that are necessary to avoid the
         imposition of federal excise tax or has paid or provided for the
         payment of any excise tax imposed for any such calendar year;

                  (g)      During the five-year period ending on the date of the
         Reorganization, neither AAF nor any person related to AAF (as defined
         in Section 1.368-1(e)(3) of the Federal income tax regulations adopted
         pursuant to the Code without regard to Section 1.368-1(e)(3)(i)(A))
         will have directly or through any transaction, agreement, or
         arrangement with any other person, (i) acquired shares of a Current
         Fund for consideration other than shares of such Current Fund, except
         for shares redeemed in the ordinary course of such Current Fund's
         business as an open-end investment company as required by the 1940 Act,
         or (ii) made distributions with respect to a Current Fund's

                                      AP-5



         shares, except for (a) distributions necessary to satisfy the
         requirements of Sections 852 and 4982 of the Code for qualification as
         a regulated investment company and avoidance of excise tax liability
         and (b) additional distributions, to the extent such additional
         distributions do not exceed 50 percent of the value (without giving
         effect to such distributions) of the proprietary interest in such
         Current Fund at the Effective Time. There is no plan or intention of
         the Shareholders who individually own 5% or more of any Current Fund
         Shares and, to the best of AAF's knowledge, there is no plan or
         intention of the remaining Shareholders to redeem or otherwise dispose
         of any New Fund Shares to be received by them in the Reorganization.
         AAF does not anticipate dispositions of those shares at the time of or
         soon after the Reorganization to exceed the usual rate and frequency of
         redemptions of shares of the Current Fund as a series of an open-end
         investment company. Consequently, AAF is not aware of any plan that
         would cause the percentage of Shareholder interests, if any, that will
         be disposed of as a result of or at the time of the Reorganization to
         be one percent (1%) or more of the shares of the Current Fund
         outstanding as of the Effective Time;

                  (h)      The Liabilities were incurred by the Current Funds in
         the ordinary course of their business and are associated with the
         Assets;

                  (i)      AAF 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;

                  (j)      As of the Effective Time, no Current Fund will have
         outstanding any warrants, options, convertible securities, or any other
         type of rights pursuant to which any person could acquire Current Fund
         Shares except for the right of investors to acquire its shares at net
         asset value in the normal course of its business as a series of an
         open-end diversified management investment company operating under the
         1940 Act;

                  (k)      At the Effective Time, the performance of this
         Agreement with respect to a particular Current Fund shall have been
         duly authorized by all necessary action by that Current Fund's
         shareholders;

                  (l)      Throughout the five-year period ending on the date of
         the Closing, each Current Fund will have conducted its historic
         business within the meaning of Section 1.368-1(d) of the Income Tax
         Regulations under the Code in a substantially unchanged manner;

                  (m)      The fair market value of the Assets of each Current
         Fund transferred to the corresponding New Fund will equal or exceed the
         sum of the Liabilities assumed by the New Fund plus the amount of
         Liabilities, if any, to which the transferred Assets are subject; and

                  (n)      The total adjusted basis of the Assets of each
         Current Fund transferred to the corresponding New Fund will equal or
         exceed the sum of the Liabilities assumed by the New Fund plus the
         amount of Liabilities, if any, to which the transferred assets are
         subject.

                                      AP-6



         4.2      The Trust represents and warrants on its own behalf and on
behalf of each New Fund as follows:

                  (a)      The Trust is a statutory trust duly organized,
         validly existing, and in good standing under the laws of the State of
         Delaware, and its Certificate of Trust has been duly filed in the
         office of the Secretary of State of Delaware;

                  (b)      The Trust is duly registered as an open-end
         management investment company under the 1940 Act. At the Effective
         Time, the New Fund Shares to be issued pursuant to Section 2.1 of this
         Agreement shall be duly registered under the Securities Act of 1933 by
         a Registration Statement filed with the SEC;

                  (c)      At the Effective Time, each New Fund will be a duly
         established and designated series of the Trust;

                  (d)      No New Fund has commenced operations nor will it
         commence operations until after the Closing;

                  (e)      Prior to the Effective Time, there will be no issued
         and outstanding shares in any New Fund or any other securities issued
         by the Trust on behalf of any New Fund, except as provided in Section
         5.2;

                  (f)      No consideration other than New Fund Shares (and each
         New Fund's assumption of the Liabilities) will be issued in exchange
         for the Assets in the Reorganization;

                  (g)      The New Fund Shares to be issued and delivered to
         each corresponding Current Fund hereunder will, at the Effective Time,
         have been duly authorized and, when issued and delivered as provided
         herein, will be duly and validly issued and outstanding shares of the
         New Fund, fully paid and nonassessable;

                  (h)      Each New Fund will be a "fund" as defined in Section
         851(g)(2) of the Code and will meet all the requirements to qualify for
         treatment as a RIC for its taxable year in which the Reorganization
         occurs;

                  (i)      The Trust, on behalf of the New Funds, has no plan or
         intention to issue additional New Fund Shares following the
         Reorganization except for shares issued in the ordinary course of its
         business as an open-end investment company; nor does the Trust, on
         behalf of the New Funds, have any plan or intention to redeem or
         otherwise reacquire any New Fund Shares issued pursuant to the
         Reorganization, other than in the ordinary course of such business or
         to the extent necessary to comply with its legal obligation under
         Section 22(e) of the 1940 Act;

                  (j)      Each New Fund will actively continue the
         corresponding Current Fund's business in substantially the same manner
         that the Current Fund conducted that business immediately before the
         Reorganization; and no New Fund has any plan or intention to sell or
         otherwise dispose of any of the Assets, except for dispositions made in
         the ordinary course of its business or dispositions necessary to
         maintain its qualification as a

                                      AP-7



         RIC, although in the ordinary course of its business the New Fund will
         continuously review its investment portfolio (as each Current Fund did
         before the Reorganization) to determine whether to retain or dispose of
         particular stocks or securities, including those included in the
         Assets, provided, however that this Section 4.2(j) shall not preclude
         any of the combinations of funds set forth on Schedule C to this
         Agreement; and

                  (k)      There is no plan or intention for any of the New
         Funds to be dissolved or merged into another corporation or statutory
         trust or "fund" thereof (within the meaning of Section 851(g)(2) of the
         Code) following the Reorganization, provided, however that this Section
         4.2(k) shall not preclude any of the combinations of Funds set forth on
         Schedule C.

         4.3      Each of AAF and the Trust, on its own behalf and on behalf of
each Current Fund or each New Fund, as appropriate, represents and warrants as
follows:

                  (a)      The fair market value of the New Fund Shares of each
         New Fund received by each Shareholder will be equal to the fair market
         value of the Current Fund Shares of the corresponding Current Fund
         surrendered in exchange therefor;

                  (b)      Immediately following consummation of the
         Reorganization, the Shareholders will own all the New Fund Shares of
         each New Fund and will own such shares solely by reason of their
         ownership of the Current Fund Shares of the corresponding Current Fund
         immediately before the Reorganization;

                  (c)      The Shareholders will pay their own expenses, if any,
         incurred in connection with the Reorganization;

                  (d)      There is no intercompany indebtedness between a
         Current Fund and a New Fund that was issued or acquired, or will be
         settled, at a discount; and

                  (e)      Immediately following consummation of the
         Reorganization, each New Fund will hold the same assets, except for
         assets distributed to shareholders in the course of its business as a
         RIC and assets used to pay expenses incurred in connection with the
         Reorganization, and be subject to the same liabilities that the
         corresponding Current Fund held or was subject to immediately prior to
         the Reorganization. Assets used to pay (i) expenses, (ii) all
         redemptions (other than redemptions at the usual rate and frequency of
         the Current Fund as a series of an open-end investment company), and
         (iii) distributions (other than regular, normal distributions), made by
         a Current Fund after the date of this Agreement will, in the aggregate,
         constitute less than one percent (1%) of its net assets.

5.       COVENANTS.

         5.1      As soon as practicable after the date of this Agreement, AAF
shall call a meeting of the shareholders of the Current Funds (the "Shareholders
Meeting") to consider and act on this Agreement and, in connection therewith,
the sale of each Current Fund's assets and the termination of each Current Fund
as a designated series of AAF. The Board of Trustees of AAF shall recommend that
shareholders approve this Agreement and, in connection therewith, the sale

                                      AP-8



of each Current Fund's assets and the termination of each Current Fund as a
designated series of AAF. Approval of this Agreement by the shareholders of a
Current Fund will authorize AAF, and AAF hereby agrees, to vote on the matters
referred to in Sections 5.2 and 5.3 for the corresponding New Fund.

         5.2      Prior to the Closing, AAF shall acquire one New Fund Share in
each New Fund Class of each New Fund for the purpose of enabling AAF to elect
AAF's trustees as the Trust's trustees (to serve without limit in time, except
as they may resign or be removed by action of the Trust's trustees or
shareholders), to ratify the selection of the Trust's independent accountants,
and to vote on the matters referred to in Section 5.3.

         5.3      Immediately prior to the Closing, the Trust (on its own behalf
and with respect to each New Fund or each New Fund Class, as appropriate) shall
enter into a Master Investment Advisory Agreement, a Master Sub-Advisory
Agreement, if applicable, a Master Administrative Services Agreement, Master
Distribution Agreements, a Custodian Agreement, and a Transfer Agency and
Servicing Agreement; shall adopt plans of distribution pursuant to Rule 12b-l of
the 1940 Act, a multiple class plan pursuant to Rule 18f-3 of the 1940 Act; and
shall enter into or adopt, as appropriate, such other agreements and plans as
are necessary for each New Fund's operation as a series of an open-end
investment company. Each such agreement and plan shall have been approved by the
Trust's trustees and, to the extent required by law, by such of those trustees
who are not "interested persons" of the Trust (as defined in the 1940 Act) and
by AAF as the sole shareholder of each New Fund.

         5.4      AAF or the Trust, as appropriate, shall file with the SEC one
or more post-effective amendments to the Trust's Registration Statement on Form
N-lA under the Securities Act of 1933, as amended, and the 1940 Act, as amended
(the "Registration Statement"), which (i) will contain such amendments to such
Registration Statement as are determined by the Trust to be necessary and
appropriate to effect the Reorganization and (ii) will register the New Fund
Shares to be issued pursuant to Section 2.1 of this Agreement, and shall use its
best efforts to have such post-effective amendment or amendments to the
Registration Statement become effective prior to the Closing.

6.       CONDITIONS PRECEDENT.

         The obligations of AAF, on its own behalf and on behalf of each Current
Fund, and the Trust, on its own behalf and on behalf of each New Fund, will be
subject to (a) performance by the other party of all its obligations to be
performed hereunder at or before the Effective Time, (b) all representations and
warranties of the other party contained herein being true and correct in all
material respects as of the date hereof and, except as they may be affected by
the transactions contemplated hereby, as of the Effective Time, with the same
force and effect as if made on and as of the Effective Time, and (c) the further
conditions that, at or before the Effective Time:

         6.1      The shareholders of that Current Fund shall have approved this
Agreement and the transactions contemplated by this Agreement in accordance with
applicable law.

         6.2      All necessary filings shall have been made with the SEC and
state securities authorities, and no order or directive shall have been received
that any other or further action is required to permit the parties to carry out
the transactions contemplated hereby. All consents,

                                      AP-9



orders, and permits of federal, state, and local regulatory authorities
(including the SEC and state securities authorities) deemed necessary by either
AAF or the Trust to permit consummation, in all material respects, of the
transactions contemplated hereby shall have been obtained, except where failure
to obtain such consults, orders, and permits would not involve a risk of a
material adverse effect on the assets or properties of either a Current Fund or
a New Fund, provided that either AAF or the Trust may for itself waive any of
such conditions.

         6.3      Each of AAF and the Trust shall have received an opinion from
Ballard Spahr Andrews & Ingersoll, LLP as to the federal income tax consequences
mentioned below. In rendering such opinion, such counsel may rely as to factual
matters, exclusively and without independent verification, on the
representations made in this Agreement (or in separate letters of representation
that AAF and the Trust shall use their best efforts to deliver to such counsel)
and the certificates delivered pursuant to Section 3.4. Such opinion shall be
substantially to the effect that, based on the facts and assumptions stated
therein and conditioned on consummation of the Reorganization in accordance with
this Agreement, for federal income tax purposes:

                  (a)      The Reorganization will constitute a "reorganization"
         within the meaning of section 368(a) of the Code, and each Current Fund
         and each New Fund will be "a party to a reorganization" within the
         meaning of section 368(b) of the Code;

                  (b)      No gain or loss will be recognized to a Current Fund
         on the transfer of its Assets to the corresponding New Fund in exchange
         solely for the New Fund's New Fund Shares and the New Fund's assumption
         of the Current Fund's Liabilities or on the subsequent distribution of
         those New Fund Shares to its Shareholders, in constructive exchange for
         their Current Fund Shares, in liquidation of the Current Fund;

                  (c)      No gain or loss will be recognized to a New Fund on
         its receipt of the corresponding Current Fund's Assets in exchange for
         New Fund Shares and its assumption of the Current Fund's Liabilities;

                  (d)      Each New Fund's basis for the corresponding Current
         Fund's Assets will be the same as the basis thereof in the Current
         Fund's hands immediately before the Reorganization, and the New Fund's
         holding period for those Assets will include the Current Fund's holding
         period therefor;

                  (e)      A Shareholder will recognize no gain or loss on the
         constructive exchange of Current Fund Shares solely for New Fund Shares
         pursuant to the Reorganization; and

                  (f)      A Shareholder's basis for the New Fund Shares of each
         New Fund to be received in the Reorganization will be the same as the
         basis for the Current Fund Shares of the corresponding Current Fund to
         be constructively surrendered in exchange for such New Fund Shares, and
         a Shareholder's holding period for such New Fund Shares will include
         its holding period for such Current Fund Shares, provided that such
         Current Fund Shares are held as capital assets by the Shareholder at
         the Effective Time.

         6.4      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).

                                     AP-10



         At any time prior to the Closing, any of the foregoing conditions
(except those set forth in Sections 6.1 and 6.3) may be waived by the trustees
of either AAF or the Trust if, in their judgment, such waiver will not have a
material adverse effect on the interests of the Current Fund's Shareholders.

7.       EXPENSES.

         Except as otherwise provided in Section 4.3(c), all expenses incurred
in connection with the transactions contemplated by this Agreement (regardless
of whether they are consummated) will be borne by the parties as they mutually
agree.

8.       ENTIRE AGREEMENT.

         Neither party has made any representation, warranty, or covenant not
set forth herein, and this Agreement constitutes the entire agreement between
the parties.

9.       AMENDMENT.

         This Agreement may be amended, modified, or supplemented at any time,
notwithstanding its approval with respect to a Current Fund by the shareholders
of that Current Fund, in such manner as may be mutually agreed upon in writing
by the parties; provided that following such approval no such amendment shall
have a material adverse effect on the shareholders' interests.

10.      TERMINATION.

         This Agreement may be terminated with respect to a Current Fund at any
time at or prior to the Effective Time, whether before or after approval by the
shareholders of that Current Fund:

         10.1     By either AAF or the Trust (a) in the event of the other
party's material breach of any representation, warranty, or covenant contained
herein to be performed at or prior to the Effective Time, (b) if a condition to
its obligations has not been met and it reasonably appears that such condition
will not or cannot be met, or (c) if the Closing has not occurred on or before
December 31, 2003; or

         10.2     By the parties' mutual agreement.

         Except as otherwise provided in Section 7, in the event of termination
under Sections 10.1(c) or 10.2, there shall be no liability for damages on the
part of either AAF or the Trust or any Current Fund or corresponding New Fund,
to the other.

11.      MISCELLANEOUS.

         11.1     This Agreement shall be governed by and construed in
accordance with the internal laws of the State of Delaware; provided that, in
the case of any conflict between such laws and the federal securities laws, the
latter shall govern.

         11.2     Nothing expressed or implied herein is intended or shall be
construed to confer upon or give any person, firm, trust, or corporation other
than the parties and their respective successors and assigns any rights or
remedies under or by reason of this Agreement.

                                     AP-11



         11.3     The execution and delivery of this Agreement have been
authorized by the Trust's trustees, and this Agreement has been executed and
delivered by a duly authorized officer of the Trust in his or her capacity as an
officer of the Trust intending to bind the Trust as provided herein, and no
officer, trustee or shareholder of the Trust shall be personally liable for the
liabilities or obligations of the Trust incurred hereunder. The liabilities and
obligations of the Trust pursuant to this Agreement shall be enforceable against
the assets of the New Funds only and not against the assets of the Trust
generally.

                                     AP-12



         IN WITNESS WHEREOF, each party has caused this Agreement to be executed
and delivered by its duly authorized officers as of the day and year first
written above.
