Transaction in Own Shares

PHSC plc ("the Company")

Purchase of own shares

The Company announces that it used its discretionary authority on the 12
September 2008 to purchase 100,000 ordinary shares through the market at a
price of 36.5 pence per ordinary share. These 100,000 shares will be cancelled.

The Directors believe that it is appropriate to continue to purchase shares for
cancellation at suitable prices when cash flow permits, and this will improve
earnings per share.

Following their cancellation, PHSC plc will have a total of 11,351,019 Ordinary
Shares in issue. The Company does not hold any shares in treasury.
