Important Information About AIM Fund Proxies Your Clients will Receive in
January Regarding:


         o   AIM Aggressive Growth Fund       o   AIM Mid Cap Growth Fund

AIM Investments announced in November 2005 that the Board of Trustees of each of
the applicable funds listed above had approved the reorganization of six AIM
funds. The reorganizations are expected to be completed in March 2006, pending
shareholder approval. Information about the proxies can be found on
AIMinvestments.com.

         Proxies will be mailed on or about Jan. 12, 2006, to registered
shareholders (of record as of Dec. 2, 2005) of the six AIM funds listed above.
This Proxy Update describes the rationale for the proposed reorganizations and
is intended to help you answer questions from your clients.

         Shareholders who own multiple funds may receive multiple proxies.
Though they look very similar, these are not duplicates. It is important that
shareholders vote every proxy they receive. If AIM does not receive sufficient
votes to obtain a quorum, it may be necessary to send a second mailing and
postpone the shareholder meeting.

         Prior to the completion of shareholder approved reorganizations, a fund
may pay a final distribution.
