                         Grant of Options to Directors                         

The Company announces that on 12 November 2010 a total of 2,631,579 options
over the Company's Ordinary Shares were granted to Directors pursuant to the
Avacta Group plc Enterprise Management Incentive Scheme ("the EMI Scheme") and
47,648,486 options over the Company's Ordinary Shares were granted to Directors
pursuant to the Avacta Group plc Executive Share Option Scheme ("the ESO
Scheme").

The options were granted for Nil consideration with an exercise price of 0.76p
per share and are exercisable from the date of grant with 50% of the options
exercisable subject to the share price of the Company reaching an average of
1.6p and with the remaining 50% of the options exercisable subject to the share
price of the Company reaching an average of 2.0p. Both average share price
targets are to be calculated over any three month period within a three year
period from the date of grant.

As a result of these options being granted, the interests of the Directors in
options are as follows:
