(Disclosures made in accordance with DTR 3.1.2R)

The company has been notified  that, on 10 November 2009, the following directors of, and other persons discharging managerial responsibility (“PDMRs”) within, G4S plc acquired shares in the company by exercising executive share options.

The options exercised by the directors and PDMRs were granted during the period 1999 to 2001 and were therefore granted over Securicor plc shares that were subsequently rolled over into G4S plc shares at the time of the merger between Securicor and Group 4 Falck in 2004. These options were due to expire between 2009 and 2011 and the directors and PDMRs concerned considered it fiscally efficient to exercise them during the current tax year.

Details of the options exercised and the exercise prices are as follows:
