PURE WAFER PLC

(AIM: PUR)

Cancellation of remaining warrants

Pure Wafer plc ("Pure Wafer" or "the Company"), a provider of high quality silicon wafer reclaim services for many of the world's leading semiconductor manufacturers as an integral part of their cost control programmes, announces that it has agreed the cancellation of the remaining warrants issued in September 2009 with Royal Bank of Scotland plc ("RBS").

Having received notice of RBS's intention to exercise its remaining warrants, the Company has exercised its pre-existing right to cancel such warrants (details of which right were provided in the Circular to shareholders dated 22 October 2012) and accordingly the Company has elected to cancel the remaining 2,191,935 warrants. The warrants have an exercise price of 20p each. Pursuant to the terms of the warrant instrument (as set out in the said Circular), the Company is obliged to pay RBS a net amount per warrant share, being the volume-weighted average price of a Pure Wafer share on the date of exercise, namely 26 May 2015, (118.06p) less the exercise price (20p), which results in a total sum payable of £2,149,368.71.

On completion of the transaction, the RBS warrants will be surrendered and cancelled, thus avoiding any dilution to existing shareholders.
