Second dynamic tick regime for FTSE 100 Index securities

Service Announcement 001/170709 issued on 17 July 2009 notified customers of
a number of FTSE 100 securities being placed on static price format codes
equivalent to the tick sizes in FESE Table 1. The Exchange will now be
introducing SET0 to enable a dynamic FESE Table 1 price format schedule to
apply to this subset of FTSE 100 securities.

Segment SET0 will include 5 new sectors equivalent to those in the current SET1
segment and will follow the same trading schedule. The existing 12 FTSE 100
index securities that are currently on the FESE Table 1 tick regime will be
migrated to SET0 on CDS with effect from Tuesday 25 August 2009.

schedule and the initial securities available on CDS are set out in Appendix A.
