We understand that the price per share for the Class S Shares of the Funds will
be equal to the next determined net asset value per share of the Class A Shares
of the Funds.

We hereby represent that we are purchasing these shares solely for our own
account and solely for investment purposes without any intent of distributing or
reselling said shares. We further represent that disposition of said shares will
only be by direct redemption to or repurchase by the Trusts.

We further agree to provide the Trusts with at least three business day's
advance written notice of any intended redemption and agree that we will work
with the Trusts with respect to the amount of such redemption so as not to place
a burden on the Trusts and to facilitate normal portfolio management of the
Funds.

Sincerely yours,

INVESCO AIM ADVISORS, INC.
