In clause 2.1 of the Service Agreement, the term will be effective from 1 January 2012 through 31 March 2016, subject to earlier termination by you or the Company.

Your salary will be £543,000 per annum during the term.

In Clause 12 of the Service Agreement, the definition of “Termination Date” shall be amended as follows:
