                               EXERCISE OF OPTION



Quadnetics Group plc, a leader in the design, integration and control of
advanced CCTV and networked video systems, announces that it yesterday exercised
a call option to acquire the outstanding 21 per cent minority interest in its
two operating subsidiary companies. This will result in the issue of a total of
987,800 new ordinary shares in Quadnetics Group plc.



As noted in the Company's interim results for the six months ended 30 November
2002, a 21% interest in both Quadrant Video Systems plc ('QVS') and Synectic
Systems Limited ('Synectics') is held by SJC 120 Limited, a company owned by
four members of the executive management team (the 'Managers'). Under the terms
of a put and call option agreement (the 'Option Agreement') with the Managers,
the Company could reacquire this minority interest in exchange for  shares in
the Company. This arrangement was explained in a circular to shareholders dated
28 February 2002 and approved at an EGM on 26 March 2002.



As part of the terms of the Option Agreement, the Managers have undertaken to
retain in aggregate at least 80 per cent. of the shares issued to them for a
period of three years from 27 February 2002, except in certain specified
circumstances.



The total number of shares in issue will become 7,427,756.



The Company also announces that as a result of the exercise of the call option,
Mr. R Singleton, a director of the Company, will have an interest in 537,750 new
ordinary shares, representing 7.24 per cent. of the issued share capital.



Application will be made for the new ordinary shares to be admitted to AIM, with
admission expected to take place on 10 February 2003.
