Announcement of entering into an amendment of a Trading Plan by a Director

As previously announced on 31 July 2014, Mr. Will Gardiner, Chief Financial Officer and a director of the Company, entered into a Trading Plan with Equiniti Financial Services Limited (the "Agent"). Under the terms of the Trading Plan, Mr. Gardiner agreed that upon the vesting of shares in accordance with the terms of grants made to him under share plans operated by the Company, which give rise to an immediate tax liability, the Agent will sell sufficient shares in order to settle exercise costs and any tax owed in connection with that vesting.

With effect from today, 24 March 2015, Mr. Gardiner and the Agent have entered into an amendment to the Trading Plan referred to above, providing for the specific sale of an additional 25,000 shares arising from the vesting on 26 March 2015 of 104,419 ordinary shares under the CSR plc 2011 Executive Incentive Plan. The prevailing terms of the Trading Plan continue with full force and effect.
