WHAT KINDS OF CHANGES ARE BEING PROPOSED?



<PAGE>   5


You are asked to vote on:

     o    Electing trustees of your fund. Trustees are responsible for the
          general oversight of the fund's business and for assuring that the
          fund is managed in the best interests of the fund's shareholders.
          Details are presented in the section of the proxy statement titled
          "Election of Trustees."

     o    Approving a new advisory agreement with A I M Advisors, Inc. Details
          are presented in the section of the proxy statement titled "Approval
          of New Investment Advisory Agreement."

     o    Ratifying the board's selection of independent accountants. Details
          are presented in the section of the proxy statement titled
          "Ratification of Selection of KPMG LLP as Independent Accountants."

In addition, there are a number of changes proposed for individual funds. It
would be impossible to summarize all of them here. We encourage you to read your
proxy statement very carefully and other information on this website to see
which specific changes are proposed.

                                                               Back to Questions

WHY DID I RECEIVE MULTIPLE PROXIES?

Each proxy statement relates to a particular group of funds and each fund has a
set of proposals. You may receive multiple mailings, depending on which group of
funds you own, or you may receive one mailing even though you own more than one
fund. Each mailing contains proxy cards for the fund(s) you own and are entitled
to vote.

HOW DOES THE BOARD RECOMMEND THAT I VOTE?

The board recommends that you vote FOR all the proposals on the proxy card.

                                                               Back to Questions

WILL THESE CHANGES ALTER THE WAY MY FUND IS MANAGED?

AIM does not expect these changes to have a significant impact on your fund's
day-to-day management. Many of the proposed changes are designed to improve the
consistency of language and policy across funds in The AIM Family of Funds(R).
These changes also provide the funds with increased flexibility to make changes
in the future without incurring the expense of a shareholder meeting.

<PAGE>   6


WHY SHOULD I VOTE?

Every vote is important. If shareholders fail to vote their proxies, a fund may
not receive enough votes to go forward with the May 3rd shareholder meeting. If
this happens, the fund may have to make extra solicitations to obtain a quorum
or resend proxies to shareholders, incurring unnecessary additional costs.

                                                               Back to Questions

HAS AIM CONTRACTED FOR THE SERVICES OF A PROXY SOLICITOR?

Yes, AIM has hired Shareholder Communications Corporation as its proxy
solicitor. If we do not receive your vote after a reasonable amount of time, you
may receive a telephone call from them reminding you to vote your shares.

                                                              Back to Questions

WILL MY VOTE BE CONFIDENTIAL USING THE ONLINE PROXY VOTING SYSTEM?

The Web proxy voting system offered by Proxycard.com maintains a high level of
security to ensure the confidentiality of your vote. Security features include:

     o    Secure Sockets Layer (SSL) - A security measure that encrypts all
          information that travels between Proxycard.com's Web server and the
          shareholder's computer.

     o    Control Number - Each shareholder is required to enter his or her
          12-digit control number. Proxycard.com verifies the number and
          presents the holder with the appropriate proxy card for his or her
          fund(s).

     o    Firewall - To protect the confidentiality of your account records,
          Proxycard.com uses only control numbers and card codes to register
          votes. Voted positions are then periodically uploaded to our master
          database of shareholders listed as of the record date. All
          account-specific data remain behind our firewall.

HOW DO I SIGN THE PROXY CARD?

(DOES NOT APPLY IF VOTING BY PHONE OR INTERNET)

Individual Accounts: Shareholders should sign exactly as their names appear in
the account registration shown on the proxy card.

Joint Accounts: All joint owners should sign exactly as their names appear in
the registration.



<PAGE>   7


All Other Accounts: The person signing must indicate his or her capacity. For
example, if Jane A. Doe is a trustee for a trust or other entity, she should
sign, "Jane A. Doe, Trustee."

WHAT IS THE DEADLINE FOR VOTING?

All votes must be received before or at the Shareholder Meeting, which will be
held at 3:00 P.M. Central time May 3, 2000.

PROPOSAL FOR APPROVAL OF A NEW ADVISORY AGREEMENT

     o    What are you being asked to vote on?

     o    How does the proposed new advisory agreement differ from the current
          advisory agreement?

     o    What effect would it have on the fund's fee schedule?

     o    How does the board recommend that I vote on this proposal?

WHAT ARE YOU BEING ASKED TO VOTE ON?

You are asked to approve a new advisory agreement between AIM and the trust of
which your fund is a series. The advisory agreement authorizes AIM to act as
investment advisor for the fund and to supervise all aspects of the fund's
operations, including the investment and reinvestment of the cash, securities or
other properties that comprise the fund's assets, subject at all times to the
policies and control of the trustees. The advisory agreement can only be amended
with shareholder approval.

                                                               Back to Questions

HOW DOES THE PROPOSED NEW ADVISORY AGREEMENT DIFFER FROM THE CURRENT ADVISORY
AGREEMENT?

It deletes references to administrative services that are addressed in a
separate agreement and it deletes references to certain expense limitations that
are no longer applicable. It also clarifies the delegation of certain
responsibilities and the non-exclusive nature of AIM's services (i.e., that AIM
may provide services to others). The changes are more fully described in the
proxy statement.

                                                               Back to Questions

WHAT EFFECT WOULD IT HAVE ON THE FUND'S FEE SCHEDULE?

The revised advisory agreement would not change the fee schedule



<PAGE>   8


applicable to your fund, but it would allow AIM to request an additional fee for
administrative services performed in connection with securities lending. Any
such additional fee would require approval by the fund's board and would be
deducted from any additional income generated from securities lending
activities.

PROPOSAL FOR CHANGING FUNDAMENTAL INVESTMENT RESTRICTIONS

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental restriction and a
          non-fundamental restriction?

     o    Why are these changes being proposed?

     o    Where can I find further details about these changes?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's fundamental investment
restrictions. There are a number of investment restrictions that would be
changed, and it would be impossible to summarize all of them here. We encourage
you to read your proxy statement very carefully.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL RESTRICTION AND A NON-FUNDAMENTAL
RESTRICTION?

A fundamental restriction can be changed only with the approval of both the
fund's board and its shareholders, through a proxy such as this one. A
non-fundamental restriction can be changed with approval of only the fund's
board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

     o    Several of the current restrictions reflect regulatory, business or
          industry conditions or requirements that are no longer applicable.

     o    Some restrictions that previously were designated as fundamental are
          not required to be fundamental and are proposed to be designated as
          non-fundamental.



<PAGE>   9


     o    The proposed changes will make investment restrictions more consistent
          across all AIM funds.

Accordingly, the board believes changing these restrictions will enable the
funds to be managed more efficiently. In addition, this change will reduce the
number of restrictions that require a shareholder vote to be changed. Therefore,
each fund will be able to avoid the cost and delays associated with such a vote,
and thus be more flexible in the future.

WHERE CAN I FIND FURTHER DETAILS ABOUT THESE CHANGES?

Details are provided in the section of the proxy statement titled "Changes to
the Fundamental Investment Restrictions of each Fund."

PROPOSAL TO CHANGE THE INVESTMENT OBJECTIVE AND TO MAKE THE INVESTMENT OBJECTIVE
NON-FUNDAMENTAL

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental objective and a
          non-fundamental objective?

     o    Why are these changes being proposed?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's investment objective to make it
non-fundamental and to eliminate from the investment objective the types of
securities your fund proposes to purchase in pursuing that objective.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL OBJECTIVE AND A NON-FUNDAMENTAL
OBJECTIVE?

A fundamental objective can be changed only with approval of both the fund's
board and its shareholders, through a proxy statement such as this one. A
non-fundamental objective can be changed with approval of only the fund's board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

The board believes that your fund's investment objective should be separate from
a description of the types of securities it purchases. This will permit the
board to alter the types of securities your fund may purchase without also
changing the fund's investment objective. Your fund does not intend to change
the types of securities in which it invests; it is simplifying the language
describing its investment objective.

In addition, if the fund's investment objective is non-fundamental, the board
will be able to change your fund's investment objective in the future without
incurring the time and costs of a shareholder vote.

HOW DOES THE BOARD RECOMMEND THAT I VOTE ON THIS PROPOSAL?

The board recommends that you vote FOR all the proposals on the proxy card.

Voting may take place in the following ways:

     o    You may vote your shares at https://www.proxycard.com. Because
          Internet voting is the most economical way to vote your proxy, we
          encourage all our shareholders who can to use this method.

          postage-paid envelope provided in the shareholder mailings.

WHAT KINDS OF CHANGES ARE BEING PROPOSED?

You are asked to vote on:


<PAGE>   22


     o    Electing trustees of your fund. Trustees are responsible for the
          general oversight of the fund's business and for assuring that the
          fund is managed in the best interests of the fund's shareholders.
          Details are presented in the section of the proxy statement titled
          "Election of Trustees."

     o    Approving a new advisory agreement with A I M Advisors, Inc. Details
          are presented in the section of the proxy statement titled "Approval
          of New Investment Advisory Agreement."

     o    Ratifying the board's selection of independent accountants. Details
          are presented in the section of the proxy statement titled
          "Ratification of Selection of KPMG LLP as Independent Accountants."

In addition, there are a number of changes proposed for individual funds. It
would be impossible to summarize all of them here. We encourage you to read your
proxy statement very carefully and other information on this website to see
which specific changes are proposed.

                                                               Back to Questions

WHY DID I RECEIVE MULTIPLE PROXIES?

Each proxy statement relates to a particular group of funds and each fund has a
set of proposals. You may receive multiple mailings, depending on which group of
funds you own, or you may receive one mailing even though you own more than one
fund. Each mailing contains proxy cards for the fund(s) you own and are entitled
to vote.

HOW DOES THE BOARD RECOMMEND THAT I VOTE?

The board recommends that you vote FOR all the proposals on the proxy card.

                                                               Back to Questions

WILL THESE CHANGES ALTER THE WAY MY FUND IS MANAGED?

AIM does not expect these changes to have a significant impact on your fund's
day-to-day management. Many of the proposed changes are designed to improve the
consistency of language and policy across funds in The AIM Family of Funds(R).
These changes also provide the funds with increased flexibility to make changes
in the future without incurring the expense of a shareholder meeting.

                                                               Back to Questions

WHY SHOULD I VOTE?


<PAGE>   23


Every vote is important. If shareholders fail to vote their proxies, a fund may
not receive enough votes to go forward with the May 3rd shareholder meeting. If
this happens, the fund may have to make extra solicitations to obtain a quorum
or resend proxies to shareholders, incurring unnecessary additional costs.

                                                               Back to Questions

HAS AIM CONTRACTED FOR THE SERVICES OF A PROXY SOLICITOR?

Yes, AIM has hired Shareholder Communications Corporation as its proxy
solicitor. If we do not receive your vote after a reasonable amount of time, you
may receive a telephone call from them reminding you to vote your shares.

                                                               Back to Questions

WILL MY VOTE BE CONFIDENTIAL USING THE ONLINE PROXY VOTING SYSTEM?

The Web proxy voting system offered by Proxycard.com maintains a high level of
security to ensure the confidentiality of your vote. Security features include:

     o    Secure Sockets Layer (SSL) - A security measure that encrypts all
          information that travels between Proxycard.com's Web server and the
          shareholder's computer.

     o    Control Number - Each shareholder is required to enter his or her
          12-digit control number. Proxycard.com verifies the number and
          presents the holder with the appropriate proxy card for his or her
          fund(s).

     o    Firewall - To protect the confidentiality of your account records,
          Proxycard.com uses only control numbers and card codes to register
          votes. Voted positions are then periodically uploaded to our master
          database of shareholders listed as of the record date. All
          account-specific data remain behind our firewall.

HOW DO I SIGN THE PROXY CARD?

(DOES NOT APPLY IF VOTING BY PHONE OR INTERNET)

Individual Accounts: Shareholders should sign exactly as their names appear in
the account registration shown on the proxy card.

Joint Accounts: All joint owners should sign exactly as their names appear in
the registration.

All Other Accounts: The person signing must indicate his or her

PROPOSAL FOR APPROVAL OF A NEW ADVISORY AGREEMENT

     o    What are you being asked to vote on?

     o    How does the proposed new advisory agreement differ from the current
          advisory agreement?

     o    What effect would it have on the fund's fee schedule?

     o    How does the board recommend that I vote on this proposal?

WHAT ARE YOU BEING ASKED TO VOTE ON?

You are asked to approve a new advisory agreement between AIM and the trust of
which your fund is a series. The advisory agreement authorizes AIM to act as
investment advisor for the fund and to supervise all aspects of the fund's
operations, including the investment and reinvestment of the cash, securities or
other properties that comprise the fund's assets, subject at all times to the
policies and control of the trustees. The advisory agreement can only be amended
with shareholder approval.

                                                               Back to Questions

HOW DOES THE PROPOSED NEW ADVISORY AGREEMENT DIFFER FROM THE CURRENT ADVISORY
AGREEMENT?

It deletes references to administrative services that are addressed in a
separate agreement and it deletes references to certain expense limitations that
are no longer applicable. It also clarifies the delegation of certain
responsibilities and the non-exclusive nature of AIM's services (i.e., that AIM
may provide services to others). The changes are more fully described in the
proxy statement.

                                                               Back to Questions

WHAT EFFECT WOULD IT HAVE ON THE FUND'S FEE SCHEDULE?

The revised advisory agreement would not change the fee schedule applicable to
your fund, but it would allow AIM to request an additional fee for
administrative services performed in connection with securities


<PAGE>   25


lending. Any such additional fee would require approval by the fund's board and
would be deducted from any additional income generated from securities lending
activities.

PROPOSAL FOR CHANGING FUNDAMENTAL INVESTMENT RESTRICTIONS

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental restriction and a
          non-fundamental restriction?

     o    Why are these changes being proposed?

     o    Where can I find further details about these changes?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's fundamental investment
restrictions. There are a number of investment restrictions that would be
changed, and it would be impossible to summarize all of them here. We encourage
you to read your proxy statement very carefully.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL RESTRICTION AND A NON-FUNDAMENTAL
RESTRICTION?

A fundamental restriction can be changed only with the approval of both the
fund's board and its shareholders, through a proxy such as this one. A
non-fundamental restriction can be changed with approval of only the fund's
board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

     o    Several of the current restrictions reflect regulatory, business or
          industry conditions or requirements that are no longer applicable.

     o    Some restrictions that previously were designated as fundamental are
          not required to be fundamental and are proposed to be designated as
          non-fundamental.

     o    The proposed changes will make investment restrictions more consistent
          across all AIM funds.


<PAGE>   26


Accordingly, the board believes changing these restrictions will enable the
funds to be managed more efficiently. In addition, this change will reduce the
number of restrictions that require a shareholder vote to be changed. Therefore,
each fund will be able to avoid the cost and delays associated with such a vote,
and thus be more flexible in the future.

WHERE CAN I FIND FURTHER DETAILS ABOUT THESE CHANGES?

Details are provided in the section of the proxy statement titled "Changes to
the Fundamental Investment Restrictions of each Fund."

PROPOSAL TO CHANGE THE INVESTMENT OBJECTIVE AND TO MAKE THE INVESTMENT OBJECTIVE
NON-FUNDAMENTAL

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental objective and a
          non-fundamental objective?

     o    Why are these changes being proposed?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's investment objective to make it
non-fundamental and to eliminate from the investment objective the types of
securities your fund proposes to purchase in pursuing that objective.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL OBJECTIVE AND A NON-FUNDAMENTAL
OBJECTIVE?

A fundamental objective can be changed only with approval of both the fund's
board and its shareholders, through a proxy statement such as this one. A
non-fundamental objective can be changed with approval of only the fund's board.

                                                               Back to Questions


<PAGE>   27


WHY ARE THESE CHANGES BEING PROPOSED?

The board believes that your fund's investment objective should be separate from
a description of the types of securities it purchases. This will permit the
board to alter the types of securities your fund may purchase without also
changing the fund's investment objective.

In addition, if the fund's investment objective is non-fundamental, the board
will be able to change your fund's investment objective in the future without
incurring the time and costs of a shareholder vote.

HOW DOES THE BOARD RECOMMEND THAT I VOTE ON THIS PROPOSAL?

The board recommends that you vote FOR all the proposals on the proxy card.

HOW DO I VOTE?

Voting may take place in the following ways:

     o    You may vote your shares at https://www.proxycard.com. Because
          Internet voting is the most economical way to vote your proxy, we
          encourage all our shareholders who can to use this method.

     o    You may indicate your vote on the proxy card and return it in the
          postage-paid envelope provided in the shareholder mailings.

                                                               Back to Questions

WHAT KINDS OF CHANGES ARE BEING PROPOSED?

You are asked to vote on:

     o    Electing trustees of your fund. Trustees are responsible for the
          general oversight of the fund's business and for assuring that the
          fund is managed in the best interests of the fund's shareholders.
          Details are presented in the section of the proxy statement titled


<PAGE>   40


          "Election of Trustees."

     o    Approving a new advisory agreement with A I M Advisors, Inc. Details
          are presented in the section of the proxy statement titled "Approval
          of New Investment Advisory Agreement."

     o    Ratifying the board's selection of independent accountants. Details
          are presented in the section of the proxy statement titled
          "Ratification of Selection of KPMG LLP as Independent Accountants."

In addition, there are a number of changes proposed for individual funds. It
would be impossible to summarize all of them here. We encourage you to read your
proxy statement very carefully and other information on this website to see
which specific changes are proposed.

                                                               Back to Questions

WHY DID I RECEIVE MULTIPLE PROXIES?

Each proxy statement relates to a particular group of funds and each fund has a
set of proposals. You may receive multiple mailings, depending on which group of
funds you own, or you may receive one mailing even though you own more than one
fund. Each mailing contains proxy cards for the fund(s) you own and are entitled
to vote.

                                                               Back to Questions

HOW DOES THE BOARD RECOMMEND THAT I VOTE?

The board recommends that you vote FOR all the proposals on the proxy card.

                                                               Back to Questions

WILL THESE CHANGES ALTER THE WAY MY FUND IS MANAGED?

AIM does not expect these changes to have a significant impact on your fund's
day-to-day management. Many of the proposed changes are designed to improve the
consistency of language and policy across funds in The AIM Family of Funds(R).
These changes also provide the funds with increased flexibility to make changes
in the future without incurring the expense of a shareholder meeting.

                                                               Back to Questions

WHY SHOULD I VOTE?

Every vote is important. If shareholders fail to vote their proxies, a fund may
not receive enough votes to go forward with the May 3rd shareholder meeting. If
this happens, the fund may have to make extra solicitations to obtain a quorum
or resend proxies to shareholders, incurring unnecessary additional costs.

                                                               Back to Questions

HAS AIM CONTRACTED FOR THE SERVICES OF A PROXY SOLICITOR?



<PAGE>   41

Yes, AIM has hired Shareholder Communications Corporation as its proxy
solicitor. If we do not receive your vote after a reasonable amount of time, you
may receive a telephone call from them reminding you to vote your shares.

                                                               Back to Questions

WILL MY VOTE BE CONFIDENTIAL USING THE ONLINE PROXY VOTING SYSTEM?

The Web proxy voting system offered by Proxycard.com maintains a high level of
security to ensure the confidentiality of your vote. Security features include:

     o    Secure Sockets Layer (SSL) - A security measure that encrypts all
          information that travels between Proxycard.com's Web server and the
          shareholder's computer.

     o    Control Number - Each shareholder is required to enter his or her
          12-digit control number. Proxycard.com verifies the number and
          presents the holder with the appropriate proxy card for his or her
          fund(s).

     o    Firewall - To protect the confidentiality of your account records,
          Proxycard.com uses only control numbers and card codes to register
          votes. Voted positions are then periodically uploaded to our master

PROPOSAL TO REORGANIZE FUND INTO A NEW SERIES PORTFOLIO OF AIM INVESTMENT
SECURITIES FUNDS



<PAGE>   42

     o    What am I asked to vote on?

     o    What would be the main effects of this changeover?

     o    Will there be any tax consequences as a result of this reorganization?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I ASKED TO VOTE ON?

You are asked to approve the reorganization of your fund from one Delaware trust
to another. This reorganization has been proposed primarily to simplify the
organizational structure of the AIM funds and thus improve operating
efficiencies.

                                                               Back to Questions

WHAT WOULD BE THE MAIN EFFECTS OF THIS CHANGEOVER?

The fiscal year of your fund would change from December 31 to July 31. This move
would allow AIM to better serve its various fund groups and their shareholders
by distributing its workload more evenly throughout the year.

                                                               Back to Questions

WILL THERE BE ANY TAX CONSEQUENCES AS A RESULT OF THIS REORGANIZATION?

No. The reorganization will be a tax-free event under the appropriate section of
the Internal Revenue Code. Therefore, shareholders of the new funds will not
recognize gain or loss for federal income tax purposes as a result of the
reorganization.

PROPOSAL FOR APPROVAL OF A NEW ADVISORY AGREEMENT

     o    What are you being asked to vote on?

     o    How does the proposed new advisory agreement differ from the current
          advisory agreement?

     o    What effect would it have on the fund's fee schedule?

     o    How does the board recommend that I vote on this proposal?

WHAT ARE YOU BEING ASKED TO VOTE ON?

You are asked to approve a new advisory agreement between AIM and the trust of
which your fund is a series. The advisory agreement authorizes AIM to act as
investment advisor for the fund and to supervise all aspects of the fund's
operations, including the investment




<PAGE>   43


and reinvestment of the cash, securities or other properties that comprise the
fund's assets, subject at all times to the policies and control of the trustees.
The advisory agreement can only be amended with shareholder approval.

                                                               Back to Questions

HOW DOES THE PROPOSED NEW ADVISORY AGREEMENT DIFFER FROM THE CURRENT ADVISORY
AGREEMENT?

It deletes references to administrative services that are addressed
in a separate agreement and it deletes references to certain expense limitations
that are no longer applicable. It also clarifies the delegation of certain
responsibilities and the non-exclusive nature of AIM's services (i.e., that AIM
may provide services to others). The changes are more fully described in the
proxy statement.

                                                               Back to Questions

WHAT EFFECT WOULD IT HAVE ON THE FUND'S FEE SCHEDULE?

The revised advisory agreement would not change the fee schedule applicable to
your fund, but it would allow AIM to request an additional fee for
administrative services performed in connection with securities lending. Any
such additional fee would require approval by the fund's board and would be
deducted from any additional income generated from securities lending
activities.

PROPOSAL FOR CHANGING FUNDAMENTAL INVESTMENT RESTRICTIONS

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental restriction and a
          non-fundamental restriction?

     o    Why are these changes being proposed?

     o    Where can I find further details about these changes?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's fundamental investment
restrictions. There are a number of investment restrictions that would be
changed, and it would be impossible to summarize all of them here. We encourage
you to read your proxy statement very carefully.

                                                               Back to Questions


<PAGE>   44

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL RESTRICTION AND A NON-FUNDAMENTAL
RESTRICTION?

A fundamental restriction can be changed only with the approval of
both the fund's board and its shareholders, through a proxy such as this one. A
non-fundamental restriction can be changed with approval of only the fund's
board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

     o    Several of the current restrictions reflect regulatory, business or
          industry conditions or requirements that are no longer applicable.

     o    Some restrictions that previously were designated as fundamental are
          not required to be fundamental and are proposed to be designated as
          non-fundamental.

     o    The proposed changes will make investment restrictions more consistent
          across all AIM funds.

Accordingly, the board believes changing these restrictions will enable the
funds to be managed more efficiently. In addition, this change will reduce the
number of restrictions that require a shareholder vote to be changed. Therefore,
each fund will be able to avoid the cost and delays associated with such a vote,
and thus be more flexible in the future.

WHERE CAN I FIND FURTHER DETAILS ABOUT THESE CHANGES?

Details are provided in the section of the proxy statement titled "Changes to
the Fundamental Investment Restrictions of each Fund."

          encourage all our shareholders who can to use this method.

     o    You may indicate your vote on the proxy card and return it in the
          postage-paid envelope provided in the shareholder mailings.

WHAT KINDS OF CHANGES ARE BEING PROPOSED?

You are asked to vote on:

     o    Electing trustees of your fund. Trustees are responsible for the
          general oversight of the fund's business and for assuring that the

<PAGE>   57

          fund is managed in the best interests of the fund's shareholders.
          Details are presented in the section of the proxy statement titled
          "Election of Trustees."

     o    Approving a new advisory agreement with A I M Advisors, Inc. Details
          are presented in the section of the proxy statement titled "Approval
          of New Investment Advisory Agreement."

     o    Ratifying the board's selection of independent accountants. Details
          are presented in the section of the proxy statement titled
          "Ratification of Selection of KPMG LLP as Independent Accountants."

In addition, there are a number of changes proposed for individual funds. It
would be impossible to summarize all of them here. We encourage you to read your
proxy statement very carefully and other information on this website to see
which specific changes are proposed.

                                                               Back to Questions

WHY DID I RECEIVE MULTIPLE PROXIES?

Each proxy statement relates to a particular group of funds and each fund has a
set of proposals. You may receive multiple mailings, depending on which group of
funds you own, or you may receive one mailing even though you own more than one
fund. Each mailing contains proxy cards for the fund(s) you own and are entitled
to vote.

HOW DOES THE BOARD RECOMMEND THAT I VOTE?

The board recommends that you vote FOR all the proposals on the proxy card.

                                                               Back to Questions

WILL THESE CHANGES ALTER THE WAY MY FUND IS MANAGED?

AIM does not expect these changes to have a significant impact on your fund's
day-to-day management. Many of the proposed changes are designed to improve the
consistency of language and policy across funds in The AIM Family of Funds(R).
These changes also provide the funds with increased flexibility to make changes
in the future without incurring the expense of a shareholder meeting.

                                                               Back to Questions

WHY SHOULD I VOTE?

Every vote is important. If shareholders fail to vote their proxies, a fund may
not receive enough votes to go forward with the May 3rd shareholder meeting. If
this happens, the fund may have to make extra solicitations to obtain a quorum
or resend proxies to shareholders, incurring unnecessary additional costs.

<PAGE>   58

HAS AIM CONTRACTED FOR THE SERVICES OF A PROXY SOLICITOR?

Yes, AIM has hired Shareholder Communications Corporation as its proxy
solicitor. If we do not receive your vote after a reasonable amount of time, you
may receive a telephone call from them reminding you to vote your shares.

                                                               Back to Questions

WILL MY VOTE BE CONFIDENTIAL USING THE ONLINE PROXY VOTING SYSTEM?

The Web proxy voting system offered by Proxycard.com maintains a high level of
security to ensure the confidentiality of your vote. Security features include:

     o    Secure Sockets Layer (SSL) - A security measure that encrypts all
          information that travels between Proxycard.com's Web server and the
          shareholder's computer.

     o    Control Number - Each shareholder is required to enter his or her
          12-digit control number. Proxycard.com verifies the number and
          presents the holder with the appropriate proxy card for his or her
          fund(s).

     o    Firewall - To protect the confidentiality of your account records,
          Proxycard.com uses only control numbers and card codes to register
          votes. Voted positions are then periodically uploaded to our master
          database of shareholders listed as of the record date. All
          account-specific data remain behind our firewall.

HOW DO I SIGN THE PROXY CARD?

(DOES NOT APPLY IF VOTING BY PHONE OR INTERNET)

Individual Accounts: Shareholders should sign exactly as their names appear in
the account registration shown on the proxy card.

Joint Accounts: All joint owners should sign exactly as their names appear in
the registration.

All Other Accounts: The person signing must indicate his or her capacity. For
example, if Jane A. Doe is a trustee for a trust or other entity, she should
sign, "Jane A. Doe, Trustee."

WHAT IS THE DEADLINE FOR VOTING?

All votes must be received before or at the Shareholder Meeting, which will be
held at 3:00 P.M. Central time May 3, 2000.

PROPOSAL TO REORGANIZE FUND INTO A NEW SERIES PORTFOLIO OF AIM INVESTMENT
SECURITIES FUNDS

     o    What am I asked to vote on?

     o    What would be the main effects of this changeover?

     o    Will there be any tax consequences as a result of this reorganization?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I ASKED TO VOTE ON?

You are asked to approve the reorganization of your fund from one Delaware trust
to another. This reorganization has been proposed primarily to simplify the
organizational structure of the AIM funds and thus improve operating
efficiencies.

                                                               Back to Questions

WHAT WOULD BE THE MAIN EFFECTS OF THIS CHANGEOVER?

The fiscal year of your fund would change from December 31 to July 31. This move
would allow AIM to better serve its various fund groups and their shareholders
by distributing its workload more evenly throughout the year.

                                                               Back to Questions

WILL THERE BE ANY TAX CONSEQUENCES AS A RESULT OF THIS REORGANIZATION?

No. The reorganization will be a tax-free event under the appropriate section of
the Internal Revenue Code. Therefore, shareholders of the new funds will not
recognize gain or loss for federal income tax purposes as a result of the
reorganization.

PROPOSAL FOR APPROVAL OF A NEW ADVISORY AGREEMENT

     o    What are you being asked to vote on?

     o    How does the proposed new advisory agreement differ from the current
          advisory agreement?

     o    What effect would it have on the fund's fee schedule?

     o    How does the board recommend that I vote on this proposal?

WHAT ARE YOU BEING ASKED TO VOTE ON?

You are asked to approve a new advisory agreement between AIM and the trust of
which your fund is a series. The advisory agreement

<PAGE>   60

authorizes AIM to act as investment advisor for the fund and to supervise all
aspects of the fund's operations, including the investment and reinvestment of
the cash, securities or other properties that comprise the fund's assets,
subject at all times to the policies and control of the trustees. The advisory
agreement can only be amended with shareholder approval.

                                                               Back to Questions

HOW DOES THE PROPOSED NEW ADVISORY AGREEMENT DIFFER FROM THE CURRENT ADVISORY
AGREEMENT?

It deletes references to administrative services that are addressed in a
separate agreement and it deletes references to certain expense limitations that
are no longer applicable. It also clarifies the delegation of certain
responsibilities and the non-exclusive nature of AIM's services (i.e., that AIM
may provide services to others). The changes are more fully described in the
proxy statement.

                                                               Back to Questions

WHAT EFFECT WOULD IT HAVE ON THE FUND'S FEE SCHEDULE?

The revised advisory agreement would not change the fee schedule applicable to
your fund, but it would allow AIM to request an additional fee for
administrative services performed in connection with securities lending. Any
such additional fee would require approval by the fund's board and would be
deducted from any additional income generated from securities lending
activities.

PROPOSAL FOR CHANGING FUNDAMENTAL INVESTMENT RESTRICTIONS

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental restriction and a
          non-fundamental restriction?

     o    Why are these changes being proposed?

     o    Where can I find further details about these changes?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's fundamental investment
restrictions. There are a number of investment restrictions that would be
changed, and it would be impossible to summarize all of them here. We encourage
you to read your proxy statement very carefully.

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL RESTRICTION AND A NON-FUNDAMENTAL
RESTRICTION?

A fundamental restriction can be changed only with the approval of both the
fund's board and its shareholders, through a proxy such as this one. A
non-fundamental restriction can be changed with approval of only the fund's
board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

     o    Several of the current restrictions reflect regulatory, business or
          industry conditions or requirements that are no longer applicable.

     o    Some restrictions that previously were designated as fundamental are
          not required to be fundamental and are proposed to be designated as
          non-fundamental.

     o    The proposed changes will make investment restrictions more consistent
          across all AIM funds.

Accordingly, the board believes changing these restrictions will enable the
funds to be managed more efficiently. In addition, this change will reduce the
number of restrictions that require a shareholder vote to be changed. Therefore,
each fund will be able to avoid the cost and delays associated with such a vote,
and thus be more flexible in the future.

WHERE CAN I FIND FURTHER DETAILS ABOUT THESE CHANGES?

Details are provided in the section of the proxy statement titled "Changes to
the Fundamental Investment Restrictions of each Fund."

PROPOSAL TO CHANGE THE INVESTMENT OBJECTIVE AND TO MAKE THE INVESTMENT OBJECTIVE
NON-FUNDAMENTAL

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental objective and a
          non-fundamental objective?

     o    Why are these changes being proposed?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

<PAGE>   62

You are asked to approve changes to your fund's investment objective to make it
non-fundamental and to eliminate from the investment objective the types of
securities your fund proposes to purchase in pursuing that objective.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL OBJECTIVE AND A NON-FUNDAMENTAL
OBJECTIVE?

A fundamental objective can be changed only with approval of both the fund's
board and its shareholders, through a proxy statement such as this one. A
non-fundamental objective can be changed with approval of only the fund's board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

The board believes that your fund's investment objective should be separate from
a description of the types of securities it purchases. This will permit the
board to alter the types of securities your fund may purchase without also
changing the fund's investment objective. Your fund does not intend to change
the types of securities in which it invests; it is simplifying the language
describing its investment objective.

In addition, if the fund's investment objective is non-fundamental, the board
will be able to change your fund's investment objective in the future without
incurring the time and costs of a shareholder vote.

HOW DO I VOTE?

Voting may take place in the following ways:

    o    You may vote your shares at https://www.proxycard.com. Because
         Internet voting is the most economical way to vote your proxy, we
         encourage all our shareholders who can to use this method.

    o    You may indicate your vote on the proxy card and return it in the
         postage-paid envelope provided in the shareholder mailings.

                                                               Back to Questions

WHAT KINDS OF CHANGES ARE BEING PROPOSED?

You are asked to vote on:

    o    Electing trustees of your fund. Trustees are responsible for the
         general oversight of the fund's business and for assuring that the

<PAGE>   75

         fund is managed in the best interests of the fund's shareholders.
         Details are presented in the section of the proxy statement titled
         "Election of Trustees."

    o    Approving a new advisory agreement with A I M Advisors, Inc. Details
         are presented in the section of the proxy statement titled "Approval of
         New Investment Advisory Agreement."

    o    Ratifying the board's selection of independent accountants. Details are
         presented in the section of the proxy statement titled "Ratification of
         Selection of KPMG LLP as Independent Accountants."

In addition, there are a number of changes proposed for individual funds. It
would be impossible to summarize all of them here. We encourage you to read your
proxy statement very carefully and other information on this website to see
which specific changes are proposed.

                                                               Back to Questions

WHY DID I RECEIVE MULTIPLE PROXIES?

Each proxy statement relates to a particular group of funds and each fund has a
set of proposals. You may receive multiple mailings, depending on which group of
funds you own, or you may receive one mailing even though you own more than one
fund. Each mailing contains proxy cards for the fund(s) you own and are entitled
to vote.

HOW DOES THE BOARD RECOMMEND THAT I VOTE?

The board recommends that you vote FOR all the proposals on the proxy card.

                                                               Back to Questions

WILL THESE CHANGES ALTER THE WAY MY FUND IS MANAGED?

AIM does not expect these changes to have a significant impact on your fund's
day-to-day management. Many of the proposed changes are designed to improve the
consistency of language and policy across funds in The AIM Family of Funds(R).
These changes also provide the funds with increased flexibility to make changes
in the future without incurring the expense of a shareholder meeting.

                                                               Back to Questions

WHY SHOULD I VOTE?

Every vote is important. If shareholders fail to vote their proxies, a fund may
not receive enough votes to go forward with the May 3rd shareholder meeting. If
this happens, the fund may have to make extra solicitations to obtain a quorum
or resend proxies to shareholders, incurring unnecessary additional costs.

                                                               Back to Questions


<PAGE>   76

HAS AIM CONTRACTED FOR THE SERVICES OF A PROXY SOLICITOR?

Yes, AIM has hired Shareholder Communications Corporation as its proxy
solicitor. If we do not receive your vote after a reasonable amount of time, you
may receive a telephone call from them reminding you to vote your shares.

                                                               Back to Questions


WILL MY VOTE BE CONFIDENTIAL USING THE ONLINE PROXY VOTING SYSTEM?

The Web proxy voting system offered by Proxycard.com maintains a high level of
security to ensure the confidentiality of your vote. Security features include:

    o    Secure Sockets Layer (SSL) - A security measure that encrypts all
         information that travels between Proxycard.com's Web server and the
         shareholder's computer.

    o    Control Number - Each shareholder is required to enter his or her
         12-digit control number. Proxycard.com verifies the number and presents
         the holder with the appropriate proxy card for his or her fund(s).

    o    Firewall - To protect the confidentiality of your account records,
         Proxycard.com uses only control numbers and card codes to register
         votes. Voted positions are then periodically uploaded to our master
         database of shareholders listed as of the record date. All
         account-specific data remain behind our firewall.

HOW DO I SIGN THE PROXY CARD?

(DOES NOT APPLY IF VOTING BY PHONE OR INTERNET)

Individual Accounts: Shareholders should sign exactly as their names appear in
the account registration shown on the proxy card.

Joint Accounts: All joint owners should sign exactly as their names appear in
the registration.

All Other Accounts: The person signing must indicate his or her capacity. For
example, if Jane A. Doe is a trustee for a trust or other entity, she should
sign, "Jane A. Doe, Trustee."

PROPOSAL TO REORGANIZE FUND INTO A NEW SERIES PORTFOLIO OF AIM INVESTMENT
SECURITIES FUNDS

    o    What am I asked to vote on?

    o    What would be the main effects of this changeover?

    o    Will there be any tax consequences as a result of this reorganization?

    o    How does the board recommend that I vote on this proposal?

WHAT AM I ASKED TO VOTE ON?

You are asked to approve the reorganization of your fund from one Delaware trust
to another. This reorganization has been proposed primarily to simplify the
organizational structure of the AIM funds and thus improve operating
efficiencies.

                                                               Back to Questions

WHAT WOULD BE THE MAIN EFFECTS OF THIS CHANGEOVER?

The fiscal year of your fund would change from December 31 to July 31. This move
would allow AIM to better serve its various fund groups and their shareholders
by distributing its workload more evenly throughout the year.

                                                               Back to Questions

WILL THERE BE ANY TAX CONSEQUENCES AS A RESULT OF THIS REORGANIZATION?

No. The reorganization will be a tax-free event under the appropriate section of
the Internal Revenue Code. Therefore, shareholders of the new funds will not
recognize gain or loss for federal income tax purposes as a result of the
reorganization.

PROPOSAL FOR APPROVAL OF A NEW ADVISORY AGREEMENT

    o    What are you being asked to vote on?

    o    How does the proposed new advisory agreement differ from the current
         advisory agreement?

    o    What effect would it have on the fund's fee schedule?

    o    How does the board recommend that I vote on this proposal?

WHAT ARE YOU BEING ASKED TO VOTE ON?

You are asked to approve a new advisory agreement between AIM and the trust of
which your fund is a series. The advisory agreement

<PAGE>   78

authorizes AIM to act as investment advisor for the fund and to supervise all
aspects of the fund's operations, including the investment and reinvestment of
the cash, securities or other properties that comprise the fund's assets,
subject at all times to the policies and control of the trustees. The advisory
agreement can only be amended with shareholder approval.

                                                               Back to Questions

HOW DOES THE PROPOSED NEW ADVISORY AGREEMENT DIFFER FROM THE CURRENT ADVISORY
AGREEMENT?

It deletes references to administrative services that are addressed in a
separate agreement and it deletes references to certain expense limitations that
are no longer applicable. It also clarifies the delegation of certain
responsibilities and the non-exclusive nature of AIM's services (i.e., that AIM
may provide services to others). The changes are more fully described in the
proxy statement.

                                                               Back to Questions

WHAT EFFECT WOULD IT HAVE ON THE FUND'S FEE SCHEDULE?

The revised advisory agreement would not change the fee schedule applicable to
your fund, but it would allow AIM to request an additional fee for
administrative services performed in connection with securities lending. Any
such additional fee would require approval by the fund's board and would be
deducted from any additional income generated from securities lending
activities.

PROPOSAL FOR CHANGING FUNDAMENTAL INVESTMENT RESTRICTIONS

    o    What am I being asked to vote on?

    o    What is the difference between a fundamental restriction and a
         non-fundamental restriction?

    o    Why are these changes being proposed?

    o    Where can I find further details about these changes?

    o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's fundamental investment
restrictions. There are a number of investment restrictions that would be
changed, and it would be impossible to summarize all of them here. We encourage
you to read your proxy statement very carefully.

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL RESTRICTION AND A NON-FUNDAMENTAL
RESTRICTION?

A fundamental restriction can be changed only with the approval of both the
fund's board and its shareholders, through a proxy such as this one. A
non-fundamental restriction can be changed with approval of only the fund's
board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

    o    Several of the current restrictions reflect regulatory, business or
         industry conditions or requirements that are no longer applicable.

    o    Some restrictions that previously were designated as fundamental are
         not required to be fundamental and are proposed to be designated as
         non-fundamental.

    o    The proposed changes will make investment restrictions more consistent
         across all AIM funds.

Accordingly, the board believes changing these restrictions will enable the
funds to be managed more efficiently. In addition, this change will reduce the
number of restrictions that require a shareholder vote to be changed. Therefore,
each fund will be able to avoid the cost and delays associated with such a vote,
and thus be more flexible in the future.

WHERE CAN I FIND FURTHER DETAILS ABOUT THESE CHANGES?

Details are provided in the section of the proxy statement titled "Changes to
the Fundamental Investment Restrictions of each Fund."

PROPOSAL TO CHANGE THE INVESTMENT OBJECTIVE AND TO MAKE THE INVESTMENT OBJECTIVE
NON-FUNDAMENTAL

    o    What am I being asked to vote on?

    o    What is the difference between a fundamental objective and a
         non-fundamental objective?

    o    Why are these changes being proposed?

    o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?


<PAGE>   80

You are asked to approve changes to your fund's investment objective to make it
non-fundamental and to eliminate from the investment objective the types of
securities your fund proposes to purchase in pursuing that objective.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL OBJECTIVE AND A NON-FUNDAMENTAL
OBJECTIVE?

A fundamental objective can be changed only with approval of both the
fund's board and its shareholders, through a proxy statement such as this one. A
non-fundamental objective can be changed with approval of only the fund's board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

The board believes that your fund's investment objective should be separate from
a description of the types of securities it purchases. This will permit the
board to alter the types of securities your fund may purchase without also
changing the fund's investment objective. Your fund does not intend to change
the types of securities in which it invests; it is simplifying the language
describing its investment objective.

In addition, if the fund's investment objective is non-fundamental, the board
will be able to change your fund's investment objective in the future without
incurring the time and costs of a shareholder vote.

We encourage you to read the proxy statement in full; however, the following
represent some typical questions that shareholders may have regarding the proxy
statement.

GENERAL QUESTIONS & ANSWERS

     o    How do I vote?

     o    What kinds of changes are being proposed?

     o    Why did I receive multiple proxies?

     o    How does the board recommend that I vote?

     o    Will these changes alter the way my fund is managed?

     o    Why should I vote?

     o    What is the deadline for voting?

HOW DO I VOTE?

Voting may take place in the following ways:

     o    You may vote your shares at https://www.proxycard.com. Because
          Internet voting is the most economical way to vote your proxy, we
          encourage all our shareholders who can to use this method.

     o    You may indicate your vote on the proxy card and return it in the
          postage-paid envelope provided in the shareholder mailings.

     o    You may call in your vote to Shareholder Communications Corporation at
          1-800-605-9205.

     o    You may attend the meeting in person and vote your shares there.

                                                               Back to Questions

WHAT KINDS OF CHANGES ARE BEING PROPOSED?

You are asked to vote on:

     o    Electing trustees of your fund. Trustees are responsible for the
          general oversight of the fund's business and for assuring that the



<PAGE>   94

          fund is managed in the best interests of the fund's shareholders.
          Details are presented in the section of the proxy statement titled
          "Election of Trustees."

     o    Approving a new advisory agreement with A I M Advisors, Inc. Details
          are presented in the section of the proxy statement titled "Approval
          of New Investment Advisory Agreement."

     o    Ratifying the board's selection of independent accountants. Details
          are presented in the section of the proxy statement titled
          "Ratification of Selection of KPMG LLP as Independent Accountants."

In addition, there are a number of changes proposed for individual funds. It
would be impossible to summarize all of them here. We encourage you to read your
proxy statement very carefully and other information on this website to see
which specific changes are proposed.

                                                               Back to Questions

WHY DID I RECEIVE MULTIPLE PROXIES?

Each proxy statement relates to a particular group of funds and each fund has a
set of proposals. You may receive multiple mailings, depending on which group of
funds you own, or you may receive one mailing even though you own more than one
fund. Each mailing contains proxy cards for the fund(s) you own and are entitled
to vote.

                                                               Back to Questions

HOW DOES THE BOARD RECOMMEND THAT I VOTE?

The board recommends that you vote FOR all the proposals on the proxy card.

                                                               Back to Questions

WILL THESE CHANGES ALTER THE WAY MY FUND IS MANAGED?

AIM does not expect these changes to have a significant impact on your fund's
day-to-day management. Many of the proposed changes are designed to improve the
consistency of language and policy across funds in The AIM Family of Funds(R).
These changes also provide the funds with increased flexibility to make changes
in the future without incurring the expense of a shareholder meeting.

                                                               Back to Questions

WHY SHOULD I VOTE?

Every vote is important. If shareholders fail to vote their proxies, a fund may
not receive enough votes to go forward with the May 3rd shareholder meeting. If
this happens, the fund may have to make extra solicitations to obtain a quorum
or resend proxies to shareholders, incurring unnecessary additional costs.

<PAGE>   95

HAS AIM CONTRACTED FOR THE SERVICES OF A PROXY SOLICITOR?

Yes, AIM has hired Shareholder Communications Corporation as its proxy
solicitor. If we do not receive your vote after a reasonable amount of time, you
may receive a telephone call from them reminding you to vote your shares.

                                                               Back to Questions

WILL MY VOTE BE CONFIDENTIAL USING THE ONLINE PROXY VOTING SYSTEM?

The Web proxy voting system offered by Proxycard.com maintains a high level of
security to ensure the confidentiality of your vote. Security features include:

     o    Secure Sockets Layer (SSL) - A security measure that encrypts all
          information that travels between Proxycard.com's Web server and the
          shareholder's computer.

     o    Control Number - Each shareholder is required to enter his or her
          12-digit control number. Proxycard.com verifies the number and
          presents the holder with the appropriate proxy card for his or her
          fund(s).

     o    Firewall - To protect the confidentiality of your account records,
          Proxycard.com uses only control numbers and card codes to register
          votes. Voted positions are then periodically uploaded to our master
          database of shareholders listed as of the record date. All
          account-specific data remain behind our firewall.

HOW DO I SIGN THE PROXY CARD?

(DOES NOT APPLY IF VOTING BY PHONE OR INTERNET)

Individual Accounts: Shareholders should sign exactly as their names appear in
the account registration shown on the proxy card.

Joint Accounts: All joint owners should sign exactly as their names appear in
the registration.

All Other Accounts: The person signing must indicate his or her capacity. For
example, if Jane A. Doe is a trustee for a trust or other entity, she should
sign, "Jane A. Doe, Trustee."

held at 3:00 P.M. Central time May 3, 2000.

PROPOSAL TO REORGANIZE FUND INTO A NEW SERIES PORTFOLIO OF AIM INVESTMENT
SECURITIES FUNDS

     o    What am I asked to vote on?

     o    What would be the main effects of this changeover?

     o    Will there be any tax consequences as a result of this reorganization?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I ASKED TO VOTE ON?

You are asked to approve the reorganization of your fund from one Delaware trust
to another. This reorganization has been proposed primarily to simplify the
organizational structure of the AIM funds and thus improve operating
efficiencies.

                                                               Back to Questions

WHAT WOULD BE THE MAIN EFFECTS OF THIS CHANGEOVER?

The fiscal year of your fund would change from December 31 to July 31. This move
would allow AIM to better serve its various fund groups and their shareholders
by distributing its workload more evenly throughout the year.

                                                               Back to Questions

WILL THERE BE ANY TAX CONSEQUENCES AS A RESULT OF THIS REORGANIZATION?

No. The reorganization will be a tax-free event under the appropriate section of
the Internal Revenue Code. Therefore, shareholders of the new funds will not
recognize gain or loss for federal income tax purposes as a result of the
reorganization.

HOW DOES THE BOARD RECOMMEND THAT I VOTE ON THIS PROPOSAL?

The board recommends that you vote FOR this proposal.

PROPOSAL FOR APPROVAL OF A NEW ADVISORY AGREEMENT

     o    What are you being asked to vote on?

     o    How does the proposed new advisory agreement differ from the current
          advisory agreement?

     o    What effect would it have on the fund's fee schedule?

     o    How does the board recommend that I vote on this proposal?

WHAT ARE YOU BEING ASKED TO VOTE ON?

You are asked to approve a new advisory agreement between AIM and the trust of
which your fund is a series. The advisory agreement





<PAGE>   97


authorizes AIM to act as investment advisor for the fund and to supervise all
aspects of the fund's operations, including the investment and reinvestment of
the cash, securities or other properties that comprise the fund's assets,
subject at all times to the policies and control of the trustees. The advisory
agreement can only be amended with shareholder approval.

HOW DOES THE PROPOSED NEW ADVISORY AGREEMENT DIFFER FROM THE CURRENT ADVISORY
AGREEMENT?

It deletes references to administrative services that are addressed
in a separate agreement and it deletes references to certain expense limitations
that are no longer applicable. It also clarifies the delegation of certain
responsibilities and the non-exclusive nature of AIM's services (i.e., that AIM
may provide services to others). The changes are more fully described in the
proxy statement.

                                                               Back to Questions

WHAT EFFECT WOULD IT HAVE ON THE FUND'S FEE SCHEDULE?

The revised advisory agreement would not change the fee schedule applicable to
your fund, but it would allow AIM to request an additional fee for
administrative services performed in connection with securities lending. Any
such additional fee would require approval by the fund's board and would be
deducted from any additional income generated from securities lending
activities.

PROPOSAL FOR CHANGING FUNDAMENTAL INVESTMENT RESTRICTIONS

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental restriction and a
          non-fundamental restriction?

     o    Why are these changes being proposed?

     o    Where can I find further details about these changes?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's fundamental investment
restrictions. There are a number of investment restrictions that would be
changed, and it would be impossible to summarize all of them here. We encourage
you to read your proxy statement very carefully.

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL RESTRICTION AND A NON-FUNDAMENTAL
RESTRICTION?

A fundamental restriction can be changed only with the approval of
both the fund's board and its shareholders, through a proxy such as this one. A
non-fundamental restriction can be changed with approval of only the fund's
board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

     o    Several of the current restrictions reflect regulatory, business or
          industry conditions or requirements that are no longer applicable.

     o    Some restrictions that previously were designated as fundamental are
          not required to be fundamental and are proposed to be designated as
          non-fundamental.

     o    The proposed changes will make investment restrictions more consistent
          across all AIM funds.

Accordingly, the board believes changing these restrictions will enable the
funds to be managed more efficiently. In addition, this change will reduce the
number of restrictions that require a shareholder vote to be changed. Therefore,
each fund will be able to avoid the cost and delays associated with such a vote,
and thus be more flexible in the future.

WHERE CAN I FIND FURTHER DETAILS ABOUT THESE CHANGES?

Details are provided in the section of the proxy statement titled "Changes to
the Fundamental Investment Restrictions of each Fund."

PROPOSAL FOR CHANGING THE INVESTMENT OBJECTIVE SO THAT IT IS NON-FUNDAMENTAL

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental objective and a
          non-fundamental objective?

     o    Why is this change being proposed?

     o    Will this change the types of investments the fund makes?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?



<PAGE>   99

You are asked to approve changes to your fund's investment objective to make it
non-fundamental.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL OBJECTIVE AND A NON-FUNDAMENTAL
OBJECTIVE?

A fundamental objective can be changed only with approval of both the
fund's board and its shareholders, through a proxy statement such as this one. A
non-fundamental objective can be changed with approval of only the fund's board.

                                                               Back to Questions

WHY IS THIS CHANGE BEING PROPOSED?

If the fund's investment objective is non-fundamental, the board will be able to
change your fund's investment objective in the future without incurring the time
and costs of a shareholder vote.

                                                               Back to Questions

WILL THIS CHANGE THE TYPES OF INVESTMENTS THE FUND MAKES?

No. There are no current plans to change the investment objective of the fund,
at this present time, if this proposal is approved.

WHAT KINDS OF CHANGES ARE BEING PROPOSED?

You are asked to vote on:

    o    Electing trustees of your fund. Trustees are responsible for the
         general oversight of the fund's business and for assuring that the


<PAGE>   113

         fund is managed in the best interests of the fund's shareholders.
         Details are presented in the section of the proxy statement titled
         "Election of Trustees."

    o    Approving a new advisory agreement with A I M Advisors, Inc. Details
         are presented in the section of the proxy statement titled "Approval of
         New Investment Advisory Agreement."

    o    Ratifying the board's selection of independent accountants. Details are
         presented in the section of the proxy statement titled "Ratification of
         Selection of KPMG LLP as Independent Accountants."

In addition, there are a number of changes proposed for individual funds. It
would be impossible to summarize all of them here. We encourage you to read your
proxy statement very carefully and other information on this website to see
which specific changes are proposed.

WHY DID I RECEIVE MULTIPLE PROXIES?

Each proxy statement relates to a particular group of funds and each fund has a
set of proposals. You may receive multiple mailings, depending on which group of
funds you own, or you may receive one mailing even though you own more than one
fund. Each mailing contains proxy cards for the fund(s) you own and are entitled
to vote.

HOW DOES THE BOARD RECOMMEND THAT I VOTE?

The board recommends that you vote FOR all the proposals on the proxy card.

WILL THESE CHANGES ALTER THE WAY MY FUND IS MANAGED?

AIM does not expect these changes to have a significant impact on your fund's
day-to-day management. Many of the proposed changes are designed to improve the
consistency of language and policy across funds in The AIM Family of Funds(R).
These changes also provide the funds with increased flexibility to make changes
in the future without incurring the expense of a shareholder meeting.

                                                               Back to Questions

WHY SHOULD I VOTE?

Every vote is important. If shareholders fail to vote their proxies, a fund may
not receive enough votes to go forward with the May 3rd shareholder meeting. If
this happens, the fund may have to make extra solicitations to obtain a quorum
or resend proxies to shareholders, incurring unnecessary additional costs.

HAS AIM CONTRACTED FOR THE SERVICES OF A PROXY SOLICITOR?

Yes, AIM has hired Shareholder Communications Corporation as its proxy
solicitor. If we do not receive your vote after a reasonable amount of time, you
may receive a telephone call from them reminding you to vote your shares.

WILL MY VOTE BE CONFIDENTIAL USING THE ONLINE PROXY VOTING SYSTEM?

The Web proxy voting system offered by Proxycard.com maintains a high level of
security to ensure the confidentiality of your vote. Security features include:

    o    Secure Sockets Layer (SSL) - A security measure that encrypts all
         information that travels between Proxycard.com's Web server and the
         shareholder's computer.

    o    Control Number - Each shareholder is required to enter his or her
         12-digit control number. Proxycard.com verifies the number and presents
         the holder with the appropriate proxy card for his or her fund(s).

    o    Firewall - To protect the confidentiality of your account records,
         Proxycard.com uses only control numbers and card codes to register
         votes. Voted positions are then periodically uploaded to our master
         database of shareholders listed as of the record date. All
         account-specific data remain behind our firewall.

HOW DO I SIGN THE PROXY CARD?

(DOES NOT APPLY IF VOTING BY PHONE OR INTERNET)

Individual Accounts: Shareholders should sign exactly as their names appear in
the account registration shown on the proxy card.

Joint Accounts: All joint owners should sign exactly as their names appear in
the registration.

All Other Accounts: The person signing must indicate his or her capacity. For
example, if Jane A. Doe is a trustee for a trust or other entity, she should
sign, "Jane A. Doe, Trustee."

PROPOSAL TO REORGANIZE FUND INTO A NEW SERIES PORTFOLIO OF AIM INVESTMENT
SECURITIES FUNDS

    o    What am I asked to vote on?

    o    What would be the main effects of this changeover?

    o    Will there be any tax consequences as a result of this reorganization?

    o    How does the board recommend that I vote on this proposal?

WHAT AM I ASKED TO VOTE ON?

You are asked to approve the reorganization of your fund from one Delaware trust
to another. This reorganization has been proposed primarily to simplify the
organizational structure of the AIM funds and thus improve operating
efficiencies.

                                                               Back to Questions

WHAT WOULD BE THE MAIN EFFECTS OF THIS CHANGEOVER?

The fiscal year of your fund would change from December 31 to July 31. This move
would allow AIM to better serve its various fund groups and their shareholders
by distributing its workload more evenly throughout the year.

                                                               Back to Questions

WILL THERE BE ANY TAX CONSEQUENCES AS A RESULT OF THIS REORGANIZATION?

No. The reorganization will be a tax-free event under the appropriate section of
the Internal Revenue Code. Therefore, shareholders of the new funds will not
recognize gain or loss for federal income tax purposes as a result of the
reorganization.

PROPOSAL FOR APPROVAL OF A NEW ADVISORY AGREEMENT

    o    What are you being asked to vote on?

    o    How does the proposed new advisory agreement differ from the current
         advisory agreement?

    o    What effect would it have on the fund's fee schedule?

    o    How does the board recommend that I vote on this proposal?

WHAT ARE YOU BEING ASKED TO VOTE ON?

You are asked to approve a new advisory agreement between AIM and the trust of
which your fund is a series. The advisory agreement


<PAGE>   116

authorizes AIM to act as investment advisor for the fund and to supervise all
aspects of the fund's operations, including the investment and reinvestment of
the cash, securities or other properties that comprise the fund's assets,
subject at all times to the policies and control of the trustees. The advisory
agreement can only be amended with shareholder approval.

                                                               Back to Questions

HOW DOES THE PROPOSED NEW ADVISORY AGREEMENT DIFFER FROM THE CURRENT ADVISORY
AGREEMENT?

It deletes references to administrative services that are addressed
in a separate agreement and it deletes references to certain expense limitations
that are no longer applicable. It also clarifies the delegation of certain
responsibilities and the non-exclusive nature of AIM's services (i.e., that AIM
may provide services to others). The changes are more fully described in the
proxy statement.

                                                               Back to Questions

WHAT EFFECT WOULD IT HAVE ON THE FUND'S FEE SCHEDULE?

The revised advisory agreement would not change the fee schedule applicable to
your fund, but it would allow AIM to request an additional fee for
administrative services performed in connection with securities lending. Any
such additional fee would require approval by the fund's board and would be
deducted from any additional income generated from securities lending
activities.

PROPOSAL FOR CHANGING FUNDAMENTAL INVESTMENT RESTRICTIONS

    o    What am I being asked to vote on?

    o    What is the difference between a fundamental restriction and a
         non-fundamental restriction?

    o    Why are these changes being proposed?

    o    Where can I find further details about these changes?

    o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's fundamental investment
restrictions. There are a number of investment restrictions that would be
changed, and it would be impossible to summarize all of them here. We encourage
you to read your proxy statement very carefully.

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL RESTRICTION AND A NON-FUNDAMENTAL
RESTRICTION?

A fundamental restriction can be changed only with the approval of
both the fund's board and its shareholders, through a proxy such as this one. A
non-fundamental restriction can be changed with approval of only the fund's
board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

    o    Several of the current restrictions reflect regulatory, business or
         industry conditions or requirements that are no longer applicable.

    o    Some restrictions that previously were designated as fundamental are
         not required to be fundamental and are proposed to be designated as
         non-fundamental.

    o    The proposed changes will make investment restrictions more consistent
         across all AIM funds.

Accordingly, the board believes changing these restrictions will enable the
funds to be managed more efficiently. In addition, this change will reduce the
number of restrictions that require a shareholder vote to be changed. Therefore,
each fund will be able to avoid the cost and delays associated with such a vote,
and thus be more flexible in the future.

WHERE CAN I FIND FURTHER DETAILS ABOUT THESE CHANGES?

Details are provided in the section of the proxy statement titled "Changes to
the Fundamental Investment Restrictions of each Fund."

PROPOSAL TO CHANGE THE INVESTMENT OBJECTIVE AND TO MAKE THE INVESTMENT OBJECTIVE
NON-FUNDAMENTAL

    o    What am I being asked to vote on?

    o    What is the difference between a fundamental objective and a
         non-fundamental objective?

    o    Why are these changes being proposed?

    o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?


<PAGE>   118

You are asked to approve changes to your fund's investment objective to make it
non-fundamental and to eliminate from the investment objective the types of
securities your fund proposes to purchase in pursuing that objective.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL OBJECTIVE AND A NON-FUNDAMENTAL
OBJECTIVE?

A fundamental objective can be changed only with approval of both the
fund's board and its shareholders, through a proxy statement such as this one. A
non-fundamental objective can be changed with approval of only the fund's board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

The board believes that your fund's investment objective should be separate from
a description of the types of securities it purchases. This will permit the
board to alter the types of securities your fund may purchase without also
changing the fund's investment objective.  Your fund does not intend to change
the types of securities in which it invests; it is simplifying the language
describing its investment objective.

In addition, if the fund's investment objective is non-fundamental, the board
will be able to change your fund's investment objective in the future without
incurring the time and costs of a shareholder vote.

statement.

HOW DO I VOTE?

Voting may take place in the following ways:

     o    You may vote your shares at https://www.proxycard.com. Because
          Internet voting is the most economical way to vote your proxy, we
          encourage all our shareholders who can to use this method.

     o    You may indicate your vote on the proxy card and return it in the
          postage-paid envelope provided in the shareholder mailings.

     o    You may call in your vote to Shareholder Communications Corporation at
          1-800-605-9205.

                                                               Back to Questions

WHAT KINDS OF CHANGES ARE BEING PROPOSED?

You are asked to vote on:

     o    Electing trustees of your fund. Trustees are responsible for the
          general oversight of the fund's business and for assuring that the
          fund is managed in the best interests of the fund's shareholders.
          Details are presented in the section of the proxy statement titled



<PAGE>   132

          "Election of Trustees."

     o    Approving a new advisory agreement with A I M Advisors, Inc. Details
          are presented in the section of the proxy statement titled "Approval
          of New Investment Advisory Agreement."

     o    Ratifying the board's selection of independent accountants. Details
          are presented in the section of the proxy statement titled
          "Ratification of Selection of KPMG LLP as Independent Accountants."

In addition, there are a number of changes proposed for individual funds. It
would be impossible to summarize all of them here. We encourage you to read your
proxy statement very carefully and other information on this website to see
which specific changes are proposed.

                                                               Back to Questions

WHY DID I RECEIVE MULTIPLE PROXIES?

Each proxy statement relates to a particular group of funds and each fund has a
set of proposals. You may receive multiple mailings, depending on which group of
funds you own, or you may receive one mailing even though you own more than one
fund. Each mailing contains proxy cards for the fund(s) you own and are entitled
to vote.

                                                               Back to Questions

HOW DOES THE BOARD RECOMMEND THAT I VOTE?

The board recommends that you vote FOR all the proposals on the proxy card.

                                                               Back to Questions

WILL THESE CHANGES ALTER THE WAY MY FUND IS MANAGED?

AIM does not expect these changes to have a significant impact on your fund's
day-to-day management. Many of the proposed changes are designed to improve the
consistency of language and policy across funds in The AIM Family of Funds(R).
These changes also provide the funds with increased flexibility to make changes
in the future without incurring the expense of a shareholder meeting.

                                                               Back to Questions

WHY SHOULD I VOTE?

Every vote is important. If shareholders fail to vote their proxies, a fund may
not receive enough votes to go forward with the May 3rd shareholder meeting. If
this happens, the fund may have to make extra solicitations to obtain a quorum
or resend proxies to shareholders, incurring unnecessary additional costs.

                                                               Back to Questions

HAS AIM CONTRACTED FOR THE SERVICES OF A PROXY SOLICITOR?


<PAGE>   133

Yes, AIM has hired Shareholder Communications Corporation as its proxy
solicitor. If we do not receive your vote after a reasonable amount of time, you
may receive a telephone call from them reminding you to vote your shares.

                                                               Back to Questions

WILL MY VOTE BE CONFIDENTIAL USING THE ONLINE PROXY VOTING SYSTEM?

The Web proxy voting system offered by Proxycard.com maintains a high level of
security to ensure the confidentiality of your vote. Security features include:

     o    Secure Sockets Layer (SSL) - A security measure that encrypts all
          information that travels between Proxycard.com's Web server and the
          shareholder's computer.

     o    Control Number - Each shareholder is required to enter his or her
          12-digit control number. Proxycard.com verifies the number and
          presents the holder with the appropriate proxy card for his or her
          fund(s).

     o    Firewall - To protect the confidentiality of your account records,
          Proxycard.com uses only control numbers and card codes to register
          votes. Voted positions are then periodically uploaded to our master
          database of shareholders listed as of the record date. All
          account-specific data remain behind our firewall.

HOW DO I SIGN THE PROXY CARD?

(DOES NOT APPLY IF VOTING BY PHONE OR INTERNET)

Individual Accounts: Shareholders should sign exactly as their names appear in
the account registration shown on the proxy card.

Joint Accounts: All joint owners should sign exactly as their names appear in
the registration.

All Other Accounts: The person signing must indicate his or her capacity. For
example, if Jane A. Doe is a trustee for a trust or other entity, she should
sign, "Jane A. Doe, Trustee."

WHAT IS THE DEADLINE FOR VOTING?

All votes must be received before or at the Shareholder Meeting, which will be
held at 3:00 P.M. Central time May 3, 2000.

PROPOSAL FOR APPROVAL OF A NEW ADVISORY AGREEMENT



<PAGE>   134

     o    What are you being asked to vote on?

     o    How does the proposed new advisory agreement differ from the current
          advisory agreement?

     o    What effect would it have on the fund's fee schedule?

     o    How does the board recommend that I vote on this proposal?

WHAT ARE YOU BEING ASKED TO VOTE ON?

You are asked to approve a new advisory agreement between AIM and the trust of
which your fund is a series. The advisory agreement authorizes AIM to act as
investment advisor for the fund and to supervise all aspects of the fund's
operations, including the investment and reinvestment of the cash, securities or
other properties that comprise the fund's assets, subject at all times to the
policies and control of the trustees. The advisory agreement can only be amended
with shareholder approval.

                                                               Back to Questions

HOW DOES THE PROPOSED NEW ADVISORY AGREEMENT DIFFER FROM THE CURRENT ADVISORY
AGREEMENT?

It deletes references to administrative services that are addressed
in a separate agreement and it deletes references to certain expense limitations
that are no longer applicable. It also clarifies the delegation of certain
responsibilities and the non-exclusive nature of AIM's services (i.e., that AIM
may provide services to others). The changes are more fully described in the
proxy statement.

                                                               Back to Questions

WHAT EFFECT WOULD IT HAVE ON THE FUND'S FEE SCHEDULE?

The revised advisory agreement would not change the fee schedule applicable to
your fund, but it would allow AIM to request an additional fee for
administrative services performed in connection with securities lending. Any
such additional fee would require approval by the fund's board and would be
deducted from any additional income generated from securities lending
activities.

HOW DOES THE BOARD RECOMMEND THAT I VOTE ON THIS PROPOSAL?

PROPOSAL FOR CHANGING FUNDAMENTAL INVESTMENT RESTRICTIONS

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental restriction and a
          non-fundamental restriction?

     o    Why are these changes being proposed?


<PAGE>   135

     o    Where can I find further details about these changes?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's fundamental investment
restrictions. There are a number of investment restrictions that would be
changed, and it would be impossible to summarize all of them here. We encourage
you to read your proxy statement very carefully.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL RESTRICTION AND A NON-FUNDAMENTAL
RESTRICTION?

A fundamental restriction can be changed only with the approval of both the
fund's board and its shareholders, through a proxy such as this one. A
non-fundamental restriction can be changed with approval of only the fund's
board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

     o    Several of the current restrictions reflect regulatory, business or
          industry conditions or requirements that are no longer applicable.

     o    Some restrictions that previously were designated as fundamental are
          not required to be fundamental and are proposed to be designated as
          non-fundamental.

     o    The proposed changes will make investment restrictions more consistent
          across all AIM funds.

Accordingly, the board believes changing these restrictions will enable the
funds to be managed more efficiently. In addition, this change will reduce the
number of restrictions that require a shareholder vote to be changed. Therefore,
each fund will be able to avoid the cost and delays associated with such a vote,
and thus be more flexible in the future.

WHERE CAN I FIND FURTHER DETAILS ABOUT THESE CHANGES?

Details are provided in the section of the proxy statement titled "Changes to
the Fundamental Investment Restrictions of each Fund."

PROPOSAL TO CHANGE THE INVESTMENT OBJECTIVE AND TO MAKE


<PAGE>   136

THE INVESTMENT OBJECTIVE NON-FUNDAMENTAL

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental objective and a
          non-fundamental objective?

     o    Why are these changes being proposed?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's investment objective to make it
non-fundamental and to eliminate from the investment objective the types of
securities your fund proposes to purchase in pursuing that objective.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL OBJECTIVE AND A NON-FUNDAMENTAL
OBJECTIVE?

A fundamental objective can be changed only with approval of both the
fund's board and its shareholders, through a proxy statement such as this one. A
non-fundamental objective can be changed with approval of only the fund's board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

The board believes that your fund's investment objective should be separate from
a description of the types of securities it purchases. This will permit the
board to alter the types of securities your fund may purchase without also
changing the fund's investment objective.

In addition, if the fund's investment objective is non-fundamental, the board
will be able to change your fund's investment objective in the future without
incurring the time and costs of a shareholder vote.

HOW DOES THE BOARD RECOMMEND THAT I VOTE ON THIS PROPOSAL?

The board recommends that you vote FOR all the proposals on the proxy card.

represent some typical questions that shareholders may have regarding the proxy
statement.

GENERAL QUESTIONS & ANSWERS

     o    What kinds of changes are being proposed?

     o    Why did I receive multiple proxies?

HOW DO I VOTE?

Voting may take place in the following ways:

     o    You may vote your shares at https://www.proxycard.com. Because
          Internet voting is the most economical way to vote your proxy, we
          encourage all our shareholders who can to use this method.

     o    You may indicate your vote on the proxy card and return it in the
          postage-paid envelope provided in the shareholder mailings.

                                                               Back to Questions

WHAT KINDS OF CHANGES ARE BEING PROPOSED?

You are asked to vote on:

     o    Electing trustees of your fund. Trustees are responsible for the
          general oversight of the fund's business and for assuring that the
          fund is managed in the best interests of the fund's shareholders.
          Details are presented in the section of the proxy statement titled


<PAGE>   150


          "Election of Trustees."

     o    Approving a new advisory agreement with A I M Advisors, Inc. Details
          are presented in the section of the proxy statement titled "Approval
          of New Investment Advisory Agreement."

     o    Ratifying the board's selection of independent accountants. Details
          are presented in the section of the proxy statement titled
          "Ratification of Selection of KPMG LLP as Independent Accountants."

In addition, there are a number of changes proposed for individual funds. It
would be impossible to summarize all of them here. We encourage you to read your
proxy statement very carefully and other information on this website to see
which specific changes are proposed.

                                                               Back to Questions

WHY DID I RECEIVE MULTIPLE PROXIES?

Each proxy statement relates to a particular group of funds and each fund has a
set of proposals. You may receive multiple mailings, depending on which group of
funds you own, or you may receive one mailing even though you own more than one
fund. Each mailing contains proxy cards for the fund(s) you own and are entitled
to vote.

                                                               Back to Questions

HOW DOES THE BOARD RECOMMEND THAT I VOTE?

The board recommends that you vote FOR all the proposals on the proxy card.

                                                               Back to Questions
WILL THESE CHANGES ALTER THE WAY MY FUND IS MANAGED?

AIM does not expect these changes to have a significant impact on your fund's
day-to-day management. Many of the proposed changes are designed to improve the
consistency of language and policy across funds in The AIM Family of Funds(R).
These changes also provide the funds with increased flexibility to make changes
in the future without incurring the expense of a shareholder meeting.

                                                               Back to Questions
WHY SHOULD I VOTE?

Every vote is important. If shareholders fail to vote their proxies, a fund may
not receive enough votes to go forward with the May 3rd shareholder meeting. If
this happens, the fund may have to make extra solicitations to obtain a quorum
or resend proxies to shareholders, incurring unnecessary additional costs.

                                                               Back to Questions

HAS AIM CONTRACTED FOR THE SERVICES OF A PROXY SOLICITOR?


<PAGE>   151


Yes, AIM has hired Shareholder Communications Corporation as its proxy
solicitor. If we do not receive your vote after a reasonable amount of time, you
may receive a telephone call from them reminding you to vote your shares.

                                                               Back to Questions

WILL MY VOTE BE CONFIDENTIAL USING THE ONLINE PROXY VOTING SYSTEM?

The Web proxy voting system offered by Proxycard.com maintains a high level of
security to ensure the confidentiality of your vote. Security features include:

     o    Secure Sockets Layer (SSL) - A security measure that encrypts all
          information that travels between Proxycard.com's Web server and the
          shareholder's computer.

     o    Control Number - Each shareholder is required to enter his or her
          12-digit control number. Proxycard.com verifies the number and
          presents the holder with the appropriate proxy card for his or her
          fund(s).

     o    Firewall - To protect the confidentiality of your account records,
          Proxycard.com uses only control numbers and card codes to register
          votes. Voted positions are then periodically uploaded to our master
          database of shareholders listed as of the record date. All
          account-specific data remain behind our firewall.

HOW DO I SIGN THE PROXY CARD?

(DOES NOT APPLY IF VOTING BY PHONE OR INTERNET)

Individual Accounts: Shareholders should sign exactly as their names appear in
the account registration shown on the proxy card.

Joint Accounts: All joint owners should sign exactly as their names appear in
the registration.

All Other Accounts: The person signing must indicate his or her capacity. For
example, if Jane A. Doe is a trustee for a trust or other entity, she should
sign, "Jane A. Doe, Trustee."

PROPOSAL FOR APPROVAL OF A NEW ADVISORY AGREEMENT


<PAGE>   152


     o    What are you being asked to vote on?

     o    How does the proposed new advisory agreement differ from the current
          advisory agreement?

     o    What effect would it have on the fund's fee schedule?

     o    How does the board recommend that I vote on this proposal?

WHAT ARE YOU BEING ASKED TO VOTE ON?

You are asked to approve a new advisory agreement between AIM and the trust of
which your fund is a series. The advisory agreement authorizes AIM to act as
investment advisor for the fund and to supervise all aspects of the fund's
operations, including the investment and reinvestment of the cash, securities or
other properties that comprise the fund's assets, subject at all times to the
policies and control of the trustees. The advisory agreement can only be amended
with shareholder approval.

                                                               Back to Questions

HOW DOES THE PROPOSED NEW ADVISORY AGREEMENT DIFFER FROM THE CURRENT ADVISORY
AGREEMENT?

It deletes references to administrative services that are addressed in a
separate agreement and it deletes references to certain expense limitations that
are no longer applicable. It also clarifies the delegation of certain
responsibilities and the non-exclusive nature of AIM's services (i.e., that AIM
may provide services to others). The changes are more fully described in the
proxy statement.

                                                               Back to Questions

WHAT EFFECT WOULD IT HAVE ON THE FUND'S FEE SCHEDULE?

The revised advisory agreement would not change the fee schedule applicable to
your fund, but it would allow AIM to request an additional fee for
administrative services performed in connection with securities lending. Any
such additional fee would require approval by the fund's board and would be
deducted from any additional income generated from securities lending
activities.

PROPOSAL FOR CHANGING FUNDAMENTAL INVESTMENT RESTRICTIONS

     o    What am I being asked to vote on?

     o    What is the difference between a fundamental restriction and a
          non-fundamental restriction?

     o    Why are these changes being proposed?


<PAGE>   153


     o    Where can I find further details about these changes?

     o    How does the board recommend that I vote on this proposal?

WHAT AM I BEING ASKED TO VOTE ON?

You are asked to approve changes to your fund's fundamental investment
restrictions. There are a number of investment restrictions that would be
changed, and it would be impossible to summarize all of them here. We encourage
you to read your proxy statement very carefully.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL RESTRICTION AND A NON-FUNDAMENTAL
RESTRICTION?

A fundamental restriction can be changed only with the approval of both the
fund's board and its shareholders, through a proxy such as this one. A
non-fundamental restriction can be changed with approval of only the fund's
board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

     o    Several of the current restrictions reflect regulatory, business or
          industry conditions or requirements that are no longer applicable.

     o    Some restrictions that previously were designated as fundamental are
          not required to be fundamental and are proposed to be designated as
          non-fundamental.

     o    The proposed changes will make investment restrictions more consistent
          across all AIM funds.

Accordingly, the board believes changing these restrictions will enable the
funds to be managed more efficiently. In addition, this change will reduce the
number of restrictions that require a shareholder vote to be changed. Therefore,
each fund will be able to avoid the cost and delays associated with such a vote,
and thus be more flexible in the future.

WHERE CAN I FIND FURTHER DETAILS ABOUT THESE CHANGES?

Details are provided in the section of the proxy statement titled "Changes to
the Fundamental Investment Restrictions of each Fund."

HOW DOES THE BOARD RECOMMEND THAT I VOTE ON THIS PROPOSAL?

You are asked to approve changes to your fund's investment objective to make it
non-fundamental and to eliminate from the investment objective the types of
securities your fund proposes to purchase in pursuing that objective.

                                                               Back to Questions

WHAT IS THE DIFFERENCE BETWEEN A FUNDAMENTAL OBJECTIVE AND A NON-FUNDAMENTAL
OBJECTIVE?

A fundamental objective can be changed only with approval of both the fund's
board and its shareholders, through a proxy statement such as this one. A
non-fundamental objective can be changed with approval of only the fund's board.

                                                               Back to Questions

WHY ARE THESE CHANGES BEING PROPOSED?

The board believes that your fund's investment objective should be separate from
a description of the types of securities it purchases. This will permit the
board to alter the types of securities your fund may purchase without also
changing the fund's investment objective. Your fund does not intend to change
the types of securities in which it invests; it is simplifying the language
describing its investment objective.

In addition, if the fund's investment objective is non-fundamental, the board
will be able to change your fund's investment objective in the future without
incurring the time and costs of a shareholder vote.

                                                               Back to Questions

HOW DOES THE BOARD RECOMMEND THAT I VOTE ON THIS PROPOSAL?

The board recommends that you vote FOR all the proposals on the proxy card.
