Major Contract Extension

16 October 2009 Corero PLC ("Corero" or "the Group") Corero Signs Major Contract Extension with Large Global Investment Bank Corero, the specialist provider of software solutions to the banking and securities and education markets, is pleased to announce that it has signed a major contract extension with a large global investment bank for its Radica CAPS software. The bank, a customer since 2003, has purchased a perpetual licence, for an unlimited number of users, to use the software across all its processing centres in Europe, Asia and the United States. The contract will provide Corero with significant revenue in the year ending 31 December 2009, the result of which will be that the operating profit of the Group for the current year will be greater than that for 2008 and in excess of current market expectations, although it will have the effect of reducing future support revenues from this customer. Mark Robertson, Managing Director, Corero Financial Markets division commented: "Radica CAPS enables securities firms to automate the entire lifecycle of a corporate actions process. I am delighted that this large investment bank has decided to continue to use it as the basis of its global corporate actions processing platform. This deal will ensure that the Financial Markets division of Corero makes a significant contribution to the Group's operating profit in 2009."
