APPENDIX

About the Star Energy SIP

In 2013, the Company adopted an Inland Revenue approved Share Investment Plan for all employees of the Group. The scheme is a tax efficient incentive plan pursuant to which all Company employees are eligible to subscribe for up to GBP150 (or 10% of salary, if less) worth of Star Energy ordinary shares per month. On a three-monthly basis, the Company matches employees' monthly subscriptions on a 1-to-1 basis and, subject to the Company having met pre-defined quarterly production targets, will increase the matching element for that quarter to 2-to-1. To receive their allocation of matching shares, employees must ordinarily remain employed by the Company for a period of 3 years. Shares issued under the SIP are held by the SIP Trustees.

Under the SIP, during the vesting period the recipient retains the voting rights and dividend rights associated with the matching allocation shares however, is unable to sell the shares until the vesting criteria have been fulfilled. The matching allocation shares will be issued to the Company's Employee Benefit Trust and held until vesting conditions have been met. The participant retains the full rights over any subscription shares.
