an offer to sell or the solicitation of an offer to buy nor shall there be any
sale of the units in any state in which such offer, solicitation or sale would
be unlawful prior to registration or qualification under the securities laws of
any such state.

   (Incorporated herein by reference is the final prospectus from Invesco Unit
