PROXY VOTING

                    PROXY VOTING INFORMATION

                    A proxy statement was mailed on or about December 28, 2007
                    to shareholders of record as of the close of business on
                    November 30, 2007, for the funds listed below. The purpose
                    of each proxy statement was to request approval of various
                    proposals, such as election of trustees, approval of a new
                    sub-advisory agreement, approval of an amendment to the
                    Trust's Agreement and Declaration of Trust, etc. Each proxy
                    statement contained disclosure information about the
                    proposals for which votes have been solicited.

                    A meeting of fund shareholders was held on February 29, 2008,
                    as scheduled, but was adjourned for the AIM Funds
                    listed below until March 28, 2008, at 3:00pm Central Time in
                    order to solicit additional votes. The reconvened meeting
                    will be held at the same location.

                    If your fund's shareholder meeting has been adjourned until
                    March 28, 2008, you still have time to vote your fund's
                    shares. You can access your fund's proxy statement,
                    common questions regarding your fund's proposals, prospectus,
                    and annual report by clicking on the fund name listed below.
