offering of equity units, Assured intends to grant the underwriters a 13-day
option to purchase up to an additional 450,000 equity units, or $22.5 million.
The equity units will initially consist of a forward purchase contract and a 5%
undivided beneficial ownership interest in $1,000 principal amount senior note
due 2014 to be issued by Assured Guaranty U.S. Holdings, Inc., a subsidiary of
Assured. The senior notes will be fully and unconditionally guaranteed by
