Alizyme PLC

01 May 2009

Today's closing auction call period has been extended in this security by 5
minutes.

Auction call extensions give London Stock Exchange electronic order book users a
further opportunity to review the prices and sizes of orders entered in an
individual security during the initial auction call before the execution occurs.
 A price monitoring extension is activated when the matching process would have
otherwise resulted in an execution price that is a pre-determined percentage
above or below the price of the last automated execution today.

The applicable percentage is set by reference to a security's TradElect sector.
This is set out in the Sector Breakdown tab of the TradElect Parameters document
