Pressure Technologies PLC

("Pressure Technologies" or the "Company")

Director's Interest

Pressure Technologies was informed on 8 October 2010 by Brewin Dolphin Limited ("BDL") that as of 7 October 2010 it held an indirect interest in 119,005 ordinary shares of the Company representing 1.05% of the issued ordinary share capital and voting rights of the Company. The indirect interests are in 49,984 ordinary shares held by Brewin Nominees Limited and 69,021 ordinary shares held by Giltspur Nominees Limited. Prior to the notification above, BDL had an interest in 1,130,471 ordinary shares of Pressure Technologies, representing 9.97% of the issued ordinary share capital and voting rights of the Company.

Of the previous interest of BDL referred to above, 1,000,040 ordinary shares, representing 8.82% of the issued ordinary share capital and voting rights of the Company, were held and continue to be held on behalf of John Hayward, the Chief Executive Officer of Pressure Technologies. The change of BDL's interest has arisen because certain shareholdings (including John Hayward's shareholding) are now held on an advisory basis rather than a discretionary basis by BDL. For the sake of clarity, John Hayward's beneficial interest in the share capital of the Company, being 1,000,040 ordinary shares representing 8.82% of the issued share capital of the Company, remains unchanged by this event.
