UPDATE ON MERGER DISCUSSIONS

Further to its announcement on 23 March, OGS confirms today that it has
commenced discussions with three further interested parties regarding a
potential offer for the Company, in addition to the offers made for the
Company by Cambridge Antibody Technology Group plc ("CAT") and Celltech
Group plc ("Celltech"). Reflecting the level of their interest, each of
these three parties has entered into a non-disclosure agreement with OGS
to enable them to carry out due diligence on the Company. The interested
parties comprise an international pharmaceutical company, a US based
biotechnology company and a European private equity house.

OGS expects the discussions to reach conclusion in the second week of
April. In the light of these developments, the OGS Board* recommends that
shareholders take no action in relation to the Celltech offer. OGS also
notes Celltech's announcement on 24 March affirming that its holding in
OGS would not prevent a bidder acquiring the Company via a scheme of
arrangement.
Commenting, David Ebsworth PhD, CEO of OGS, said  "We have previously
promised our shareholders that we will seek the best value that we can
for them and in doing so are seeking to have discussions with all
interested parties. We have made progress, confirmed by today's
announcement that each of these three interested parties have entered
into a non-disclosure agreement with OGS."
