("Corero" or the "Company")

Director change

Corero Network Security plc (AIM: CNS), the network security and business software provider, has received notice that CrossHill Debt II L.P. and CrossHill Georgetown Capital L.P. ("CrossHill") no longer wish to exercise their right to be represented by a non-executive director on the Board of Corero. As a result Mr Stephen Graham, non-executive director, will resign with effect from 30 June 2012.

Mr Graham was appointed in March 2012 following CrossHill exercising its rights to appoint a non-executive director under the terms of the acquisition of Top Layer Networks Inc. CrossHill retains the right to appoint a non-executive director in the future.

The Company has commenced a process to recruit an additional independent non-executive director and will make an announcement on this in due course.

Jens Montanana, Chairman of Corero, commented "I would like to thank Stephen Graham for his contribution to the Board and thank CrossHill for their continued support as a shareholder and loan note holder."

Corero Network Security plc will be publishing a trading update for the 6 months to 30 June 2012 at the end of July and announcing its interim results in early September 2012.
