                               GRANT OF OPTIONS                                

Software Radio Technology plc ("SRT" or the "Company") announces that on 17
February 2010, Simon Tucker, Chief Executive of SRT, was granted options over
2,200,000 ordinary shares of 0.1p each in SRT at an exercise price of 9p per
share.

The options are divided into two tranches. The first tranche of 1,000,000
options will vest when the Company's closing mid-market share price has reached
at least 20p for either of (i) 10 consecutive trading days; or (ii) 15 trading
days in any 20 consecutive trading days. The second tranche of 1,200,000
options will vest when the Company's mid-market closing share price has reached
at least 35p with the same timing parameters as the first tranche.

The new options become exercisable six months from the date of vesting until 17
February 2020 and replace the 2,200,000 options previously granted to Mr.
Tucker which have been cancelled.
