further extended.

ACI and Official Payments also announced today that they have entered into a

Official Payment Holdings, et al., Case No. 8970, and in the Superior Court of
Gwinnett County of the State of Georgia captioned Giacherio v. Official
Payment Holdings, et al., Case No. 13-A-08794-8. The terms of the proposed
settlement are subject to approval of the Delaware Court of Chancery and
dismissal of the action pending in the Superior Court of Gwinnett County of
