Vesting of 2011 LTIP Awards

In accordance with the rules of the Cookson Group Long-Term Incentive Plan, the allocation of Performance and Matching Shares awarded to Francois Wanecq on 1 April 2011 vested on 1 April 2014, following the application of the performance conditions specified at the time of grant. Following the demerger in December 2012, the Awards over Cookson Group plc Shares were rolled-over to become an award over ordinary shares in Vesuvius plc (the "Company").

The Remuneration Committee awarded dividends in respect of the shares that vested. As a result, Mr Wanecq received additional shares equivalent in value to the dividends that would have accrued on the shares that vested during the three year vesting period. The shares to satisfy the vesting of these awards were sourced from Vesuvius's Employee Share Ownership Trust and Mr Wanecq has sold sufficient shares to meet his associated tax and social security liabilities and the dealing costs for selling these shares. The remaining shares for Mr Wanecq will be transferred into his own name.
