                YOUR VOTE MATTERS...WE'D LOVE TO HEAR FROM YOU!


Through shareholder meetings and the proxy process, all shareholders have a
voice in managing their mutual fund. AIM recently mailed you proxy information
for the September 1, 2000, shareholder meeting. Your vote is important to us.
If enough votes are not rendered for a quorum, we would need to resend the
proxies, which could mean unnecessary additional costs.

If you have recently submitted your proxy, we appreciate your vote and ask you
to disregard this notice.

We know most people lead busy lives, which sometimes makes it difficult to
respond before the meeting deadline. To make it easy for you to reach us, we
have set up a special phone line so you can vote your shares quickly and
easily. Please call us between 9 a.m. - 11 p.m. (EST) Monday-Friday and
12 noon - 6 p.m. (EST) on Saturday at 1-800-695-4382 and refer to the pin number
located just below your name on the left-hand side of this letter.


If we don't hear from you, a proxy specialist from the Shareholder
Communications Corporation may contact you by telephone to encourage you to
vote. We know most people would rather not be called so we are providing the
special toll-free number printed above to vote your shares now, quickly and
easily. There will be no need for a phone call from Shareholder Communications
Corporation if you call the 800 number listed above and vote your proxy
promptly.

Thank you in advance for your participation in voting on these important issues
related to your personal investment. We appreciate your time and hope that you
have a wonderful summer.
