Transaction in Own Shares

PHSC plc ("the Company")

Purchase of own shares

The Company announces that it used its discretionary authority on the 25 June
2008 to purchase 25,000 ordinary shares through the market at a price of 39
pence per ordinary share and today purchased a further 35,000 ordinary shares
at a price of 38.75 pence per ordinary share and 10,000 ordinary shares at a
price of 39 pence per ordinary share. This total of 70,000 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 11,451,019 Ordinary
Shares in issue. The Company does not hold any shares in treasury.
